There may be supine hypertension and reversal of the normal circadian blood pressure rhythm (normally lower at night) mood disorder ppt best 25 mg amitriptyline, with an increased frequency of micturition at night depression paranoia buy discount amitriptyline 25mg on line. Other features of autonomic dysfunction may be present depression symptoms shaking effective amitriptyline 50mg, including dry eyes and dry mouth (xerophthalmia anxiety back pain order amitriptyline 25mg line, xerostomia) anxiety quiz online discount 50mg amitriptyline fast delivery, a tendency to constipation depression dsm buy amitriptyline without prescription, and lack of penile erections. Guillain–Barré syndrome, amyloidosis) However, the most common cause of orthostatic hypotension in hospital practice is probably dehydration or overzealous treatment with antihypertensive or diuretic agents. Management of orthostatic hypotension consists of education on fac tors that inﬂuence blood pressure. Non-pharmacological approaches include increased salt and water intake, head-up bed tilt, and wearing elastic stockings or a G-suit. Pharmacological therapies include ﬂudrocortisone (ﬁrst line), and midodrine, ephedrine, or dihydroxyphenylserine (second line). Cross References Neuropathy; Parkinsonism; Xerophthalmia, Xerostomia -257 O Oscillopsia Oscillopsia Oscillopsia is an illusory movement of the environment due to excessive slip of images on the retina (‘retinal slip’) during active or passive head movement, producing a complaint of blurring, jumping, or oscillation of the visual repre sentation of the environment. Oscillopsia is most often due to acquired bilateral loss of vestibular function (loss of the vestibulo-ocular reﬂexes). Oscillopsia does not occur in congenital nystagmus, nor in opsoclonus, presumably due to the operation of the visual suppression mechanism which normally operates during saccadic eye movements. Oscillopsia: impaired vision during motion in the absence of the vestibulo-ocular reﬂex. Cross References Myokymia; Nystagmus; Opsoclonus; Vestibulo-ocular reﬂexes Oscillucusis Oscillucusis is an abnormal perception of an oscillation in the intensity of ambient sounds, which may occur during a migraine attack. Osmophobia Osmophobia, an aversion to smells, may form part of a migraine attack, along with photophobia and phonophobia. A distinction may be made between essential and symptomatic palatal tremor, also known as primary and secondary isolated palatal tremor. Palatal tremor may be asymptomatic or there may be a clicking sound in the inner ear, especially in essential palatal tremor. There may be associated contractions of external ocular muscles (oculopalatal myoclonus), larynx, neck, diaphragm (respiratory myoclonus, diaphragmatic ﬂutter, or Leeuwenhoek’s dis ease), trunk, and limbs, which may bring the palatal tremor to attention. Palatal myoclonus is associated with lesions interrupting pathways between the red nucleus, inferior olivary nucleus, and dentate nucleus (Guillain–Mollaret triangle). Hypertrophy of the inferior olivary nucleus may be evident neuro radiologically (structural or functional imaging) and pathologically. This is a consequence of a lesion in the dentato-olivary pathway which leads to transsy naptic degeneration and hypermetabolism of the olivary nucleus. Although many cases are essential/idiopathic, recognized symptomatic causes of palatal tremor include vascular lesions, trauma, neoplasia, demyelination, epilepsy, and, rarely, adult-onset Alexander’s disease. Drug treatment of palatal tremor is often unsuccessful, although reports of beneﬁt with 5-hydroxytryptophan, carbamazepine, sodium valproate, clon azepam, baclofen, and even sumatriptan have appeared. Cross References Eight-and-a-half syndrome; Myoclonus; Nystagmus; Oscillopsia; Tinnitus; Tremor Palilalia Palilalia is a disorder of articulation characterized by the involuntary repetition of syllables within a word, whole words, or phrases, hence a reiterative speech A. The term stutter may be used for repetition of single syllables, and the term palilogia has sometimes been used for the repetition of phrases, to distinguish from palilalia. Although sometimes classiﬁed as an illusory experience, musical hallucinations may occur concurrently. Cross References Hallucination; Illusion Palinopsia Palinopsia is an illusory visual phenomenon characterized by the persistence or recurrence of visual images immediately after the stimulus has been removed, hence visual perseveration. The description of the symptom may lead to it being mistaken for diplopia (‘pseudodiplopia’). Palinopsia occurs most frequently in the context of a left homonymous hemi anopia, secondary to right occipitotemporal or occipitoparietal lesions: these may be vascular, neoplastic, metabolic, ictal, or drug or toxin-induced. It has also been described with retinal and optic nerve disease and occasionally in normal individuals. Object-speciﬁc and “side inversed” palinopsia limited to the hemianopic ﬁeld in occipital infarction. Cross References Hemianopia; Illusion; Perseveration; Polyopia; Visual perseveration Pallaesthesia Pallaesthesia is the appreciation of vibration sensation; its loss may be described as pallanaethesia. Cross Reference Vibration Palmaris Brevis Sign Palmaris brevis sign may be useful in localizing the site of an ulnar nerve lesion. Innervated by the superﬁcial ‘sensory’ division of the ulnar nerve in the wrist (distal canal of Guyon), contraction of the palmaris brevis muscle may be evi dent with compressive lesions of the deep motor branch of the ulnar nerve which cause intrinsic hand muscle weakness but no sensory loss (‘Ramsay Hunt syn drome’): ask the patient to ‘contract’ the hypothenar eminence with the ﬁfth digit forcibly abducted and look for skin corrugation. Palmomental Reﬂex the palmomental reﬂex consists of contraction of the mentalis muscle induced by stroking the ipsilateral palm with a blunt object. It may indicate damage to the contralateral paracentral cortex or its connections, but since it is observed in about one quarter of normal adults and is very common in the normal elderly, and may occur in other conditions, both its sensitivity and speciﬁcity are low. It may be considered a frontal release sign or primitive reﬂex, but is less speciﬁc than the grasp reﬂex. Induction of the reﬂex by stimulation of areas other than the palm is more likely to be associated with cerebral damage. Cross References Age-related signs; Frontal release signs Pandysautonomia Pandysautonomia is characterized by pre and postganglionic lesions of both the sympathetic and parasympathetic pathways. Papilloedema Papilloedema is swelling (oedema) of the optic nerve head due to raised intracra nial pressure (cf. A number of stages of papilloedema are described: in the acute stage, the only ﬁndings may be oedema at the superior and inferior poles of the disc, absence of spontaneous venous pulsation, and enlargement of the blind spot. As papilloedema progresses the whole disc is involved and splinter haemorrhages may be evident at the disc margin. These early stages may be asymptomatic or may be associated with transient losses of vision (obscurations), often pro voked by activities or movements which further raise intracranial pressure, thus compromising retinal perfusion pressure. Enlargement of the blind spot and con striction of the visual ﬁeld may be evident, but visual acuity is often unimpaired (cf. Chronic papilloedema produces gliosis of the optic nerve head and eventually optic atrophy (‘sequential optic atrophy’) with nerve ﬁbre damage and permanent visual ﬁeld defects. Guillain–Barré syndrome, acid maltase deﬁciency, phrenic nerve injury, hence paradoxical abdominal movement, abdominal paradox, paradox ical breathing, or paradoxical diaphragm movement. Paradoxical diaphragm movement is a potentially alarming sign since it may indicate incipient respiratory failure. The term paradoxical breathing may also be used to describe thorax and abdomen moving in different directions when breathing, as with increased upper airway resistance. Some patients may describe this sensation as ‘numb ness’ or ‘deadness’, in which case care needs to be taken to differentiate it from anaesthesia. Some authorities reserve the term for spontaneous rather than evoked positive sensory phenomena, as a distinction from dysaesthesia. Paraesthesia is a feature of neuropathy and may occur in the distribution of a compressed or entrapped nerve, perhaps reﬂecting the mechanosensitivity of nerves in this situation. Paraesthesia is a more reliable indicator of the diagnosis of neuropathy than pain. Paraesthesia may also be provoked by hyperventilation (especially perioral, hands, and feet [acroparaes thesia]). Missed diagnosis of vitamin B12 deﬁciency presenting with paraes thetic symptoms.

Wernicke’s aphasia), as differentiated from agrammatism, the omission of function words and bound morphemes in non-ﬂuent speech. It should be remem bered that many movements previously thought to conform to this deﬁnition have subsequently been recognized to have an organic basis. The use of the word has not been entirely consistent, for example, paral ysis agitans originally used by James Parkinson to describe the disease which now bears his name. The periodic paralyses are a group of conditions characterized by episodic muscular weakness and stiffness (myotonia) associated with muta tions in the skeletal muscle voltage-gated sodium and calcium ion channel genes (channelopathies). Cross References Myotonia; Plegia Paramnesia Paramnesia is recalling as memories things which have not in fact taken place, hence a distortion of episodic or autobiographical memory. Cross References Amnesia; Confabulation; Reduplicative paramnesia 264 Paraparesis P Paramyotonia Paramyotonia is similar to myotonia in that muscle does not relax normally fol lowing contraction (voluntary, percussion), which may prompt a complaint of muscle aching or stiffness, but differs in that repetitive muscle use. For example, repeated forced voluntary eyelid closure in a patient with paramyotonia may, after several attempts, lead to a failure of volun tary eyelid opening, the eyes remaining closed for a minute or so. This type of muscle stiffness may also be sensitive to temperature, being made worse by cooling which may also provoke muscle weakness. During the delayed muscle relaxation, electrical activity is not prominent, and after muscle cooling the resting muscle membrane potential may be reduced from around the normal −80 to −40 mV, at which point muscle ﬁbres are inexcitable (contracture). Mutations in the same gene have been documented in hyperkalaemic periodic paralysis and K+-aggravated myotonia. Symptomatic treatment with membrane-stabilizing agents like mexiletine and tocainide or with the carbonic anhydrase inhibitor acetazolamide might be tried. Precautions are necessary during general anaesthesia because of the risk of diaphragm myotonia. Paramyotonia congenita and hyper kalaemic periodic paralysis are linked to the adult muscle sodium channel gene. Cross References Contracture; Myotonia; Paralysis; Warm-up phenomenon Paraparesis Paraparesis is a weakness of the lower limbs, short of complete weakness (para plegia). This may result from lesions anywhere from cerebral cortex (frontal, parasagittal lesions) to peripheral nerves, producing either an upper motor neu rone (spastic) or lower motor neurone (ﬂaccid) picture. Upper motor neurone lesions: Traumatic section of the cord; Cord compression from intrinsic or extrinsic mass lesion. Cross References Flaccidity; Myelopathy; Paraplegia; Spasticity Paraphasia Paraphasias are a feature of aphasias (disorders of language), particularly (but not exclusively) ﬂuent aphasias resulting from posterior dominant temporal lobe lesions (cf. Paraphasias refer to a range of speech output errors, both phono logical and lexical, including substitution, addition, duplication, omission, and transposition of linguistic units, affecting letters within words, letters within syllables, or words within sentences. Phonemic paraphasias may be encountered in Broca’s aphasia and conduction aphasia, when the patient may recognize them to be errors, and Wernicke’s aphasia. These may be further classiﬁed as: Semantic or categoric: substitution of a different exemplar from the same category. Verbal paraphasias showing both semantic and phonemic resemblance to the target word are called mixed errors. These types may be observed in patients with Wernicke’s aphasia, who often seem unaware of their paraphasias due to a failure of self-monitoring of output. This may result from lower motor neurone lesions involving multiple nerve roots and/or peripheral nerves. The latter may acutely produce a ﬂaccid areﬂexic picture (‘spinal shock’), but later this develops into an upper motor neurone syndrome (hypertonia, clonus, hyperreﬂexia, loss of superﬁcial reﬂexes [e. In paraplegia of upper motor neurone origin, enhanced ﬂexion defence reﬂexes (‘ﬂexor spasms’) may occur, producing hip and knee ﬂexion, ankle and toe dorsiﬂexion. Eventually such ﬂexor responses may become a ﬁxed ﬂexion deformity with secondary contractures (‘paraplegia in ﬂexion’). Prevention of this situation may be possible by avoiding spasms, which are often provoked by skin irritation or ulceration, bowel constipation, bladder infection, and poor nutrition. Physiotherapy and pharmacotherapy with agents such as baclofen, dantrolene, and tizanidine may be used; botulinum toxin injections may be help ful for focal spasticity. Since localized pain may inhibit voluntary muscular exertion, apparent weakness in such circumstances may be labelled ‘algesic pseudoparesis’. The key anatomical substrates, damage to which causes the syndrome, are probably the intersti tial nucleus of Cajal and the nucleus of the posterior commissure and their projections. Cross References Collier’s sign; Light-near pupillary dissociation; Nystagmus; Supranuclear gaze palsy Parkinsonism Parkinsonism is a clinical syndrome characterized by the presence of some or all of the following features; there is overlap with so-called akinetic-rigid syndromes in which these features predominate: Insight into the non-reality of these experiences may be retained, hence ‘pseudohallucinations’. Autonomic dysfunction, especially orthostatic hypotension Conventionally parkinsonism is viewed as a disorder of the extrapyrami dal system producing ‘extrapyramidal signs’, although this term has limitations: despite the fact that some of the cardinal features of parkinsonism (bradykinesia, rigidity, postural instability, tremor) result from pathology in the basal ganglia, particularly affecting dopaminergic pathways, other features may reﬂect cortical involvement, at least in part. The incidence of parkinsonism increases dramatically with age; it is also associated with an increased risk of death, particularly in the presence of a gait disturbance. It is crucial not to miss the diagnosis of Wilson’s disease, although rare, since in the early stages this disorder is reversible with copper chelation therapy; hence copper and caeruloplasmin should be checked in all patients with young-onset (under age 50) parkinsonism (and dystonia). Response to levodopa therapy is only reliably seen in idiopathic Parkinson’s disease, although some patients with multiple system atrophy or progres sive supranuclear palsy may beneﬁt. The features particularly responsive in Parkinson’s disease are bradykinesia and rigidity; tremor is less reliably helped.

Such smells are usually unpleasant (cacosmia), may be associated with a disagreeable taste (cacogeusia), and may be difﬁcult for the patient to deﬁne. Causes include purulent nasal infections or sinusitis and partial recovery following transection of olfactory nerve ﬁbres after head injury. Transient parosmia may presage epileptic seizures of temporal lobe corti cal origin (olfactory aura), particularly involving the medial (uncal) region. Cross References Aura; Seizures Parry–Romberg Syndrome Hemifacial atrophy is thinning of subcutaneous tissues on one side of the face; it may also involve muscle and bone (causing enophthalmos), and sometimes brain, in which case neurological features (hemiparesis, hemianopia, focal epileptic seizures, cognitive impairment) may also be present. The clinical heterogeneity of hemifacial atrophy probably reﬂects patho genetic heterogeneity. The syndrome may result from maldevelopment of auto nomic innervation or vascular supply, or as an acquired feature following trauma, or a consequence of linear scleroderma (morphoea), in which case a coup de sabre may be seen. Some observations on the aetiology of hemifacial atrophy (“Parry–Romberg syndrome”).

Initially, the rapidly fatal underlying illness, and sustained positivity of blood cultures. After 24h, there is an improvement -Non-albicans Candida species reach almost half of the Candida isolates in the hemodynamic status, clinical signs and lab results. This response to the -An early fatal outcome promoted by candidemia may be prevented with empirical treatment was a statement for the diagnosis of neurogenic shock.

Preventive anidulafungin therapy was given until resolution of the which affect the whole body. The most common baseline Candida species were Candida albicans (aggravated chronic hepatitis, decompensated liver cirrhosis, hepatic encefalopaty, (56%), C. In 15% of the Materials and Methods: this retrospective study included 113 hepatic patients isolates, the causative Candida was less susceptible or resistant to fuconazole. However, Clinical Emergency Hospital of Craiova, Romania for hidric re-equilibration and it was 44 % in patients with candidemia and 80% in patients with Candida Krusei. We extracted from patients’ electronic records the demographic, Conclusions: Non-albicans Candida species reach almost half of the Candida clinical and laboratory data. The risk remains high and adequate antifungal therapy is necessary to lead a goof outcome. This is not surprising as cirrhotic patients have an increased risk for bacterial infections. We isolated from ascitic fuid: Escherichia coli, Klebsiella, Proteus, Enterococcus, Acinetobacter, Methicillin Resistant Staphylococcus aureus and Streptococcus. Although Clinical Pulmonary Infection Score has been used Background: Pneumocystis jirovecii(known as Pneumocystis carinii) is an successfully in medical and surgical patients, the systemic infammation in this important opportunistic fungal pathogen in humans who have depressed immune population limits its utility. The most common isolated bacteria were Pseudomonas aeruginosa (n=6, patient received trimethoprim (20 mg/kg per days)sulfamethoxazole for 7 days 31,6%) and Klebsiella pneumoniae (n=6, 31,6%). Acute circulatory failure the patient demanded included Methicillin-susceptible Staphylococcus aureus, Enterococcus faecium, continuous infusion of vasopressive agents. Prone position was applied four Enterobacter cloacae, Acinetobacter baumannii and Serratia marcescens. The diagnosis was based on tuberculosis, and fungi, should be considered in all rheumatological patients on invasive cultures but the true incidence of burn respiratory infections remains to treatment who present to intensive care. Microcirculation damage and endothelial dysfunction have already been described in sepsis, but their involvement in coronary circulation still needs to be investigated. The present study aimed to assess microcirculatory and endothelial vasomotor function in an experimental model of faecal peritonitis sepsis in pigs. After anaesthesia induction, a pressure/fow wire (Volcano ComboWire) was placed in the mid-portion of the left anterior descending coronary artery under. Stimulation of angiotensin type 2 receptor attenuates Hyperaemia was obtained by intracoronary bolus of 3 mL adenosine (90 µg) and 3 mL bradykinin (10-6M) to test respectively the microcirculatory endothelium organ injury in rats with polymicrobial sepsis. However, data on regulative properties of this receptor on the sepsis response are poor. Then we measure the arterial blood pressure, heart rate, and organ function index of lung, (Ukraine), 2Kyiv Hepatobiliary and Pancreatic Surgery Center Kyiv liver and kidney. During the entire period of treatment, 178 crops were performed for all patients (drainages n=98, urine n=42, tracheal aspirates n=38); which were repeated every 3-4 days for the purpose of control agent and antibiotics sensitivity. Conclusions: Resistance to antimicrobial drugs jeopardizes effective prevention and treatment of a growing range of bacterial infections. As practice shows, to achieve Background and Goal of Study: the enormous morbidity associated with sepsis adequate blood pressure and tissue perfusion in patients with refractory septic and consequent organ failure necessitates resuscitation and treatment at the shock, it is not enough just to infuse crystalloids and vasoactive drugs. Equally important, is the prediction of outcome at admission in order to in recent years, the use of terlipressin has become a very promising treatment for differentiate patients with more severe disease and direct therapies accordingly.

Thrombocytopenia in sepsis, which occurs since catecholamines have a detrimental effect on the immune function, they due to multiple immune and non-immune mechanism, underlines deterioration of stimulate bacterial growth, and cause myocardial damage. But at the same time, the use of biomarkers to help identify patients with a high risk of mortality is appealing. A sequential organization failure all-cause mortality in adult patients with sepsis.

We identifed a total of 15 brain injured patients with intracranial Evaluation of cerebral hemodynamic was performed using doppler ultrasound of hypertension treated with barbiturates (thiopental). It can also associate with Takotsubo cardiomyopathy, sometimes leading to serious diffculties in diagnostic and treatment management. The patient was perfectly healthy before and she had no signs of trauma or intoxication. The patient had akinesia on all basal segments with hyperkinesia of the apex and an ejection fraction of 25%. After 6 hours of intensive care treatment, brain herniation occurred and the patient was determined to be brain dead. With the family’s approval, the patient’s organs were harvested for transplantation. The usual Takotsubo pattern is apical akinesia and ballooning with basal hiperkinesia. The wall motion pattern in our case report is a rarely described condition named inverted Takotsubo. In our case, the clinical suspicion of acute coronary syndrome was low because of the patient’s presentation and lack of comorbidities. However,9 the preservat ion of a coma and the coming of death in cerebral ischemic stroke patient had frequent seizures, resistant to treatment with levetiracetam, and then is the use of antiplatelet agents. Hyperuricemia most researchers viewed as an thiopental and lacosamide therapy was initiated.

This study included eight Wistar rats of the same age, gender and weight the presence of the 1st day elevated level of xanthine in the blood, dihydropyridines that were subjected to chlorpyrifos exposure. They were frst tested for baseline advisable to use in hemorrhagic stroke, regardless of the 1st day elevated levels levels of cholinesterase, cortisol, free triiodothyronine (fT3), thyroxine (fT4), of xanthine in the blood, in ischemic without this. Next samples were taken to determine the level of cholinesterase and with hyperuricemia also not using magnesium sulfate, in hemorrhagic stroke with the above mentioned parameters. Protocol procedures were Conclusion: Among all oxypurines, the level of xanthine in the blood, and not the performed under general anesthesia, according to international guidelines. Levels of cholinesterase were signifcantly decreased after exposure to chlorpyrifos, having a baseline mean value of 1471.

A slow phase with exponentially increasing veloc ity (high-gain instability mood disorder group activities buy 50mg amitriptyline with mastercard, runaway movements) may be seen in congenital or acquired pendular nystagmus depression symptoms worse at night amitriptyline 50 mg with mastercard.

Nystagmus of peripheral vestibular origin is typically reduced by ﬁxation (hence these patients hold their heads still) and enhanced by removal of visual ﬁxation (in the dark depression test in hindi generic amitriptyline 50mg without prescription, with Frenzel’s lenses). Central vestibular: unidirectional or multidirectional, 1st, 2nd or 3rd degree; typically sustained and persistent. Cerebellar/brainstem: commonly gaze-evoked due to a failure of gaze-holding mechanisms. Congenital: usually horizontal, pendular-type nystagmus; worse with ﬁxation, attention, and anxiety. It may appear with blindness of childhood onset or be acquired with neurological disease (multiple sclerosis, mitochon drial disease, Whipple’s disease, Pelizaeus–Merzbacher disease). Ataxic/dissociated: in abducting >> adducting eye, as in internuclear ophthalmoplegia and pseudointernuclear ophthalmoplegia.

Wernicke–Korsakoff’s syndrome), paraneopla sia, drugs (alcohol, phenytoin, barbiturates, sedative-hypnotic drugs), toxins, and epilepsy. Pendular nystagmus may respond to anticholinesterases, consistent with its being a result of cholinergic dysfunction. Periodic alternating nystagmus responds to baclofen, hence the importance of making this diagnosis. These symp toms are thought to reﬂect critical compromise of optic nerve head perfusion and are invariably associated with the ﬁnding of papilloedema. Obscurations mandate urgent investigation and treatment to prevent permanent visual loss. Cross Reference Papilloedema Obtundation Obtundation is a state of altered consciousness characterized by reduced alert ness and a lessened interest in the environment, sometimes described as psy chomotor retardation or torpor. An increased proportion of time is spent asleep and the patient is drowsy when awake. Cross References Coma; Psychomotor retardation; Stupor Ocular Apraxia Ocular apraxia (ocular motor apraxia) is a disorder of voluntary saccade initia tion; reﬂexive saccades and spontaneous eye movements are preserved. Ocular apraxia may be overcome by using dynamic head thrusting, with or without blinking (to suppress vestibulo-ocular reﬂexes): the desired ﬁxation point is achieved through reﬂex contraversive tonic eye movements to the midposition following the overshoot of the eyes caused by the head thrust. Ocular apraxia may occur as a congenital syndrome (in the horizontal plane only: Cogan’s syndrome), or may be acquired in ataxia telangiectasia (Louis–Bar syndrome), Niemann–Pick disease (mainly vertical plane affected), and Gaucher’s disease (horizontal plane only). Cross References Apraxia; Saccades Ocular Bobbing Ocular bobbing refers to intermittent abnormal vertical eye movements, usu ally conjugate, consisting of a fast downward movement followed by a slow return to the initial horizontal eye position. The sign has no precise localizing value, but is most commonly associated with intrinsic pontine lesions. It has also been described in encephalitis, Creutzfeldt–Jakob disease, and toxic encephalopathies. Its patho physiology is uncertain but may involve mesencephalic and medullary burst neurone centres. Inverse ocular bobbing: slow downward movement, fast return (also known as fast upward ocular bobbing or ocular dipping);. Converse ocular bobbing: slow upward movement, fast down (also known as slow upward ocular bobbing or reverse ocular dipping). Cross Reference Ocular dipping Ocular Dipping Ocular dipping, or inverse ocular bobbing, consists of a slow spontaneous down ward eye movement with a fast return to the midposition. This may be observed in anoxic coma or following prolonged status epilepticus and is thought to be a marker of diffuse, rather than focal, brain damage. Reverse ocular dipping (slow upward ocular bobbing) consists of a slow upward movement followed by a fast return to the midposition. Cross Reference Ocular bobbing Ocular Flutter Ocular ﬂutter is an eye movement disorder characterized by involuntary bursts of back-to-back horizontal saccades without an intersaccadic interval (cf. Ocular ﬂutter associated with a localized lesion in the paramedian pontine reticular formation. It has occasionally been reported with cerebellar lesions and may be under inhibitory cerebellar control. Cross References Hypotropia; Lateral medullary syndrome; Skew deviation; Synkinesia, Synkinesis; Tullio phenomenon; Vestibulo-ocular reﬂexes Oculocephalic Response Oculocephalic responses are most commonly elicited in unconscious patients; the head is passively rotated in the horizontal or vertical plane (doll’s head maneou vre) and the eye movements are observed. Conjugate eye movement in a direction opposite to that in which the head is turned is indicative of an intact brain stem (intact vestibulo-ocular reﬂexes). With pontine lesions, the oculocephalic responses may be lost, after roving eye movements but before caloric responses disappear. Cross References Caloric testing; Coma; Doll’s head manoeuvre, Doll’s eye manoeuvre; Head impulse test; Roving eye movements; Supranuclear gaze palsy; Vestibulo-ocular reﬂexes Oculogyric Crisis Oculogyric crisis is an acute dystonia of the ocular muscles, usually causing upward and lateral displacement of the eye. It is often accompanied by a dis order of attention (obsessive, persistent thoughts), with or without dystonic or dyskinetic movements. It occurs particularly with symptomatic (secondary), as opposed to idiopathic (primary), dystonias, for example, postencephalitic and neuroleptic-induced dystonia, the latter now being the most common cause. This is usually an acute effect but may on occasion be seen as a consequence of chronic therapy (tardive oculogyric crisis). It has also been described with Wilson’s dis ease, neuroleptic malignant syndrome, and organophosphate poisoning. Lesions within the lentiform nuclei have been recorded in cases with oculogyric crisis. Treatment of acute neuroleptic-induced dystonia is either parenteral benzo diazepine or an anticholinergic agent such as procyclidine, benztropine, or trihexyphenidyl. Oculogyric crisis and abnormal magnetic resonance imaging signals in bilateral lentiform nuclei. Fascicular (within substance of midbrain): all muscles or speciﬁc mus cles involved, + other clinical signs expected, such as contralateral ataxia (Claude’s syndrome), hemiparesis (Weber’s syndrome). Orbit: paresis of isolated muscle almost always from orbital lesion or muscle disease. Oculomotor nerve palsies may be distinguished as ‘pupil involving’ or ‘pupil sparing’, the former implying a ‘surgical’, the latter a ‘medical’ cause, but this distinction only holds for complete palsies. Transtentorial (uncal) 250 Onion Peel, Onion Skin O herniation due to raised intracranial pressure may, particularly in its early stages, cause an oculomotor nerve palsy due to stretching of the nerve, a ‘false-localizing sign’. In young patients this is most often due to demyelination, in the elderly to brainstem ischaemia; brainstem arteriovenous malformation or tumour may also be responsible. A vertical one-and-a-half syndrome has also been described, characterized by vertical upgaze palsy and monocular paresis of downgaze, either ipsilateral or contralateral to the lesion.

External ophthalmoplegia: weakness of the extraocular muscles of central, neuromuscular, or myopathic origin: Supranuclear: The term ‘ophthalmoplegia plus’ has been used to denote the combination of progressive external ophthalmoplegia with additional symptoms and signs, indicative of brainstem, pyramidal, endocrine, cardiac, muscular, hypothalamic, or auditory system involvement, as in mitochondrial disease. Cross References Coma; Decerebrate rigidity; Emposthotonos Oppenheim’s Sign Oppenheim’s sign is a variant method for eliciting the plantar response, by appli cation of heavy pressure to the anterior surface of the tibia, for example, with the thumb, and moving it down from the patella to the ankle. Extension of the hal lux (upgoing plantar response, Babinski’s sign) is pathological. Like Chaddock’s sign, Oppenheim’s sign always postdates the development of Babinski’s sign as a reliable indicator of corticospinal pathway (upper motor neurone) pathology. Although some normal individuals can voluntarily induce opsoclonus, gen erally it reﬂects mesencephalic or cerebellar disease affecting the omnipause cells which exert tonic inhibition of the burst neurones which generate saccades.

Cross References Ocular ﬂutter; Saccadic intrusion, Saccadic pursuit; Square wave jerks Optic Aphasia Optic aphasia is a visual modality-speciﬁc naming disorder. It has sometimes been grouped with associative visual agnosia, but these patients are not agnosic since they can demonstrate recognition of visually presented stimuli by means other than naming. Moreover, these patients are not handicapped by their deﬁcit in everyday life, whereas agnosic patients are often functionally blind. Objects that are semantically related can be appropriately sorted, indicat ing intact semantics. This is not simply anomia, since the deﬁcit is speciﬁc to visual stimuli; objects presented in tactile modality, or by sound, or by spoken deﬁnition, can be named. Naming errors are often semantic, and perseverations (‘conduit d’approche’) are common. Perception is intact, evidenced by the ability to draw accurately objects which cannot be named. Optic aphasia is associated with unilateral lesions of the left occipital cortex and subjacent white matter. Visual agnosia: disorders of object recognition and what they tell us about normal vision.

Tactile search with the palm and ﬁngers may be undertaken in searching for an object, using somatosen sory cues to compensate for impaired access to visual information. Hence this may be characterized as a modality-speciﬁc apraxia, wherein visual informa tion cannot be used to guide goal-directed movements. Optic ataxia occurs with lesions of the intraparietal sulcus and regions medial and superior to it; the primary visual cortex is intact. It is one fea ture, along with psychic paralysis of gaze (‘sticky ﬁxation’) and simultanagnosia (visual disorientation), of Balint’s syndrome in which there is some evidence for parieto-occiptial (and possibly frontal) lobe dysfunction (disconnection). Cross References Apraxia; Ataxia; Balint’s syndrome; Dysmetria; Simultanagnosia; Visual disori entation; Visual form agnosia Optic Atrophy Optic atrophy is pallor of the optic nerve head as visualized by ophthalmoscopy. The temporal disc may appear pale in a normal fundus, so that optic atrophy can only be conﬁdently diagnosed when there is also nasal pallor, although temporal pallor may follow damage to the macular ﬁbre bundle with central visual defects. Optic atrophy may be the consequence of any optic neuropathy which causes optic nerve damage leading to gliotic change of the optic nerve head. Although most often seen with optic nerve pathology, it may be a consequence of pathology in the retina, optic chiasm, or optic tract. In clinical practice a striped drum serves to test both visual pursuit and saccades. Rotation of the stripe to the left produces leftward pursuit, followed by a compensatory saccade to the right, followed by pursuit to the left of the next stripe, with another compensatory saccade, and so on. Clinical and imaging studies show a strong correlation between oro-facial dyspraxia and lesions in the frontal operculum; it may also occur with subcortical lesions involving periventricular and/or peristriatal white matter as well as the basal ganglia. Progressive loss of speech output and orofacial dyspraxia associated with frontal lobe hypometabolism. Normally there is a drop in blood pressure of lesser magnitude on standing but this is usually quickly compensated for by the barore ceptor reﬂex. Measuring blood pressure automatically by passive head-up tilt testing (tilt table) is also helpful in diagnosing orthostatic hypotension if the active standing test is negative, and the history is suggestive, or in patients with motor impairment. Symptoms which may be associated with orthostatic hypotension include exercise-induced or postprandial light-headedness, transient visual loss (usually bilateral), blackouts (syncope), and pain in a ‘coathanger’ distribution across the shoulders.

In some complex programs these requirements partially depend on the duration of missions depression definition oxford dictionary discount amitriptyline online amex, with the range of screening and monitoring modalities increasing with flight duration depression zodiac signs buy 25 mg amitriptyline free shipping. Within a particular program bipolar depression 35 purchase 25mg amitriptyline visa, medical monitoring modalities can still largely vary depending on the features of the particular mission depression cherry review purchase 50 mg amitriptyline visa. For example depression symptoms signs trusted amitriptyline 25mg, mission-specific pre and postflight monitoring modalities can depend on mission 3 V 4 Ch 3 Medical Monitoring Before and After Flight Billica et al mood disorder medication cheap amitriptyline 25 mg online. The individual pre and postflight monitoring plan is composed by the crew surgeon on the basis of program specific requirements, mission-specific factors, individual mission assignments as well as data on the individual’s responses to the previous missions, particularities, and the speed of recovery and rehabilitation processes. Real-time corrections to the individual pre and postflight monitoring program are also possible at any time to relieve any concerns of the crew surgeon. Individual Baseline Databases Health monitoring data collection is planned at fixed intervals in conjunction with the physical health evaluations at astronaut selection and before the first mission; they collectively establish a baseline normative database against which in-flight management and postflight recovery will be implemented. Prior experience has demonstrated significant diversity of individual physiological responses to space flight factors; in particular, it is believed important to establish a baseline profile for each crewmember in terms of metabolic and endocrine functions, and 19 electrolyte and acid-base balance ; prior experience has demonstrated significant diversity of individual 3,19,20 physiological responses to space flight factors. During subsequent missions, depending on available information and the clinical judgment of the crew surgeons, only select protocols may be implemented if adequate baseline data already exist. The established baseline may be re-established periodically, as clinically indicated. In the postflight phase, guided by clinical manifestations and physical evaluation, only those protocols can be implemented that are required for diagnostic purposes or to guide the rehabilitation process and the return to flight duties. Preflight Medical Evaluation and Monitoring Activities Medical fitness for flight is determined by the crew surgeon, who conducts preflight medical evaluations of all crewmembers. In Russia, data obtained from cosmonauts’ physical examinations are reviewed by the Main Medical Board of the Ministry of Public Health and the Ministry of Defense of the Russian Federation 45 days before space flight. Depending on the nature and duration of the flight, there are minimum sets of tests/examinations required at certain intervals referenced to the launch or landing date. In Russia, this is conducted in accordance with regulations put into effect by an Order from the Minister of Public Health and the Minister of Defense (see Chapter 1). The International Space Station Program has adopted most of the principles of preflight medical evaluation and monitoring that have been verified during various programs conducted by space, military, and civilian agencies in several countries, primarily the United States and Russia. Skylab and Space Shuttle programs and the Russian long-duration space flight experience aboard the Salyut and Mir stations are the main sources of current knowledge in this area. Significant contribution to the knowledge base of space medicine monitoring has been made by ground-based experiments and simulations. As described in Chapter 1, astronaut candidate finalists undergo thorough 5-day physical and laboratory exams, including a treadmill stress test; pulmonary function tests; sigmoidoscopic and imaging examinations; and exams conducted by specialists in ophthalmology, neurology, psychiatry, dentistry and otolaryngology. After selection, astronauts undergo yearly medical examinations to recertify their fitness for flight. This training includes familiarization with the medical and physiological problems encountered in microgravity, including space motion sickness, cardiovascular deconditioning, reduced-pressure effects and decompression sickness, radiation, habitability and countermeasures, and use of in-flight medical equipment. Two crewmembers are designated crew medical officers and receive additional training in diagnosing and treating common medical problems, administering intramuscular and intravenous medications, and using onboard clean-up kits for decontamination and protection from potentially hazardous contaminants. Crew medical officers are equipped with a “medical checklist,” a quick reference to common ambulatory and emergency medical problems and a complete description of all onboard medications and their side effects. All crewmembers undergo extensive preflight medical examinations in addition to those associated with biomedical research and longitudinal data collection. Preflight exams, typically scheduled 10 days and again 2 days before launch, are conducted to detect any medical problems that might require attention and to provide baselines for postflight comparison. Results from these examinations are compared to those from two postflight sessions held the day of landing and three days thereafter. In addition to the certification process, astronauts also undergo real-time medical monitoring during potentially hazardous activities, such as underwater and hypobaric-chamber training sessions and some forms of biomedical testing. Medical staff oversee all potentially hazardous activities as a means of ensuring safety and quality assurance. Russian Program Cosmonaut selection and training are considered to be an integrated, continuous process. The goal of the outpatient phase is to identify overt pathology and functional disorders that would represent absolute contraindications for space flight (Table 1). Examinations in the hospital are designed to identify latent (occult) pathology, incipient preclinical forms of disease, and slight deviations in the functional status of organs and systems, as well as to evaluate physiological functional reserves. Candidate cosmonauts undergo comprehensive assessments by internists, surgeons, otolaryngologists, dentists, neuropathologists, and psychologists. Special provocative tests also are used to evaluate the “reserve potential” of the physiological system being tested. The results of these tests and evaluations, and those from tests conducted after cosmonauts are assigned to a crew (see below), are assessed by the Medical Certification Board, which declares individuals either qualified for special training, qualified with reservations, or not qualified (see Chapter 1). Qualification with reservations usually reflects the discovery, during the evaluation process, of a medical condition that requires treatment; such individuals are deemed temporarily unfit for special training for up to 6 months. Individuals who pass the inpatient testing stage subsequently undergo special training (see Chapter 2), the goals of which are to improve tolerance and induce adaptive physiological reactions to specific space flight factors, and to impart the skills needed to control spacecraft systems and equipment. If a cosmonaut has a health problem that requires clarification or reassessment of the Board’s recommendation, then a special examination and Board session are held. Other medical assessments conducted between regular Board meetings (during the training process) are observations during tests, physical training and daily life; interim medical examinations; and quarterly in-depth medical examinations. Interim examinations (Table 2) are held before and after any training procedure that makes unusual demands on cosmonaut health. Interim exams including analysis of blood and urine, and evaluations by internists, neuropathologists, and 5 V 4 Ch 3 Medical Monitoring Before and After Flight Billica et al. If the results of preliminary interim examination are positive, the cosmonaut is allowed to participate in further tests and training. Results of the last interim examinations are used to assess the effect of training on the cosmonaut’s health and tolerance of the factors to which he or she has been exposed. Measures are taken as needed to improve physiological tolerance of particular factors. In-depth examinations (also conducted as part of the outpatient selection process) take place quarterly (Table 3). These examinations include general clinical analyses of blood, urine, and feces; cosmonauts older than 40 years also undergo tests of blood sugar and cholesterol every 6 months. Cosmonauts also are examined by specialists in internal medicine, neuropathology, surgery, otolaryngology, ophthalmology, and dentistry. Results from medical and psychological observations and from interim medical examinations during training also are considered during the in-depth examination. Tests for recertification closely resemble those of the inpatient selection phase (Tables 4 and 5). Cosmonauts undergo additional clinical and physiological tests once before they are assigned to a prime or a back-up crew, again 30 to 60 days before launch, and again 5 to 7 days before launch. When an individual is assigned to a crew, results from the last regular inpatient certification can be used if the Board finds no reason to repeat any of the component tests. The tests constituting preflight examinations are similar to those of the annual recertification but include 24-hour Holter monitoring and assessments of tolerance of low atmospheric pressure and +4 to +8 Gx accelerations. The different acceleration profiles used for annual versus preflight certifications reflect the different goals of the two processes. The annual test (tolerance of +3 Gz and 5 Gz for 30 seconds each) seeks to evaluate general tolerance and allows cosmonauts to begin flight training. Preflight certification tests (tolerance of +4 to +8 Gz) seek to predict individual tolerance of acceleration profiles expected during actual space flights. Good tolerance of transverse (+Gx) acceleration (magnitude up to 8 G, duration up to 40 seconds) has been shown to predict good tolerance of acceleration during the active phases of flight on Soyuz-type spacecraft, including emergency ejection and descent from orbit. Conditions such as contusions (with limited tissue edema), minor cuts or bruises, limited 1 or nd 2 -degree burns or frostbite, single boils that are not associated with fever or do not affect the individual’s general state, or acute infectious laryngitis and pharyngitis (without severe symptoms of toxicity) are generally treated on an outpatient basis. After either inpatient or outpatient treatment, a short period of rest (not longer than 15 days) may be prescribed, during which the cosmonaut cannot participate in training. When the recovery and rest periods are over, the cosmonaut resumes classroom work first and then special training. The final preflight medical examination takes place 5 to 7 days before launch and again on the day of launch. Launch-day evaluations are conducted by internists, neuropathologists, and otolaryngologists. Scientific studies and experiments are conducted independent of the preflight medical evaluations. These studies are conducted in accordance with special programs developed before each flight, and theoretically can include experiments in any area of physiology, medicine, pharmacology, hygiene, or psychology. The results from such studies, like those from baseline medical monitoring, can be significant in the flight certification process, although they are not a mandatory part of the decision making. At this time, a crew surgeon, deputy crew surgeon, and biomedical mission manager are assigned to the mission. Further medical data reviews and monitoring activities become the responsibility of the crew surgeon. This individual schedules and arranges for every evaluation, assessment, data sampling, and other activities. The crew surgeon ensures that all existing monitoring and preparatory requirements are satisfied and that each individual crewmember’s medical records precisely reflect all acquired information. Six months before the scheduled launch date, the crew aeromedical summaries and drug sensitivity testing records are updated. Nutritional assessment and counseling, and radiation history reviews are required at this time, and individual exercise programs are initiated. One month before launch, the crew surgeon and deputy crew surgeon meet with the crew for medical examinations and preflight medical testing to include a full flight physical examination. For short missions (less than 30 days), this session replaces the medical evaluation held 10 days before launch. Further medical examinations fall into the category of “near-flight” exams (L–10 days or closer). These evaluations are conducted at the launch site or at the training site before crew transfer to the prelaunch crew quarters. Near flight examinations are conducted to detect any medical problems that might require attention and to provide “fresh” baselines for postflight comparison. A comprehensive preflight examination is performed 10 days (for short flights) or 7 days (for intermediate or long flights) before launch. Additional studies commensurate with the annual evaluation’s requirements may be added so that this exam, if performed within 30 days of the crewmember’s birthday, will substitute for the annual exam. For short flights, this preflight medical evaluation consists of a full physical, otolaryngology and ophthalmology evaluation, cardiovascular/cardiopulmonary studies, a battery of laboratory tests, and microbiological assessments (Table 6). For long flights, nutritional assessment and repeated microbiological sampling are required. Findings are released on the crew’s health status, and this is equivalent to confirming that the crew is flight-ready. On launch day, a brief medical evaluation (several minutes long) takes place on the launch site, which terminates the preflight medical evaluation and monitoring sequence. Results from these preflight examinations are later compared to those from the postflight sessions on the day of landing and three days thereafter. After “main engine cutoff,” the crew surgeon and deputy crew surgeon return to the Johnson Space Center to begin the in-flight portion of crew medical monitoring. For a launch from Russia, the procedures for examining the crews are in keeping with the “final preflight examinations” program described above in the “Russian Program” section. Russian Program As noted earlier, the difference between medical assessment/certification and preflight countermeasures is somewhat blurred in the Russian space program, since training is considered an extension of the selection and assessment process. The primary goal of the general training is to improve cosmonauts’ physiological tolerance of space flight factors as they acquire new occupational and professional skills. Traits revealed during training, such as speed and stability of an individual’s adaptive responses, are important in evaluating a candidate’s performance. For this reason, the provocative tests used during this phase simulate space flight factors as closely as possible. Special attention is given to cosmonaut-researchers (payload specialists) during this training so that their performance and abilities can be expanded as much as possible. Some means by which general conditioning is improved have 7 V 4 Ch 3 Medical Monitoring Before and After Flight Billica et al. As the durations of space flight continue to increase, it becomes apparent that maintaining the adaptive capacities of crewmembers during those flights will necessitate the development of additional prophylactic countermeasures that can be used both during preflight training as well as during actual missions. Program Many preflight activities have been implemented to protect crew health before launch and to prevent medical problems that could delay or impair missions. The Health Stabilization Program was designed to minimize crew exposure to infectious disease before missions. The brevity of early Mercury and Gemini flights was such that the possibility of infectious diseases manifesting themselves during flight was not considered a concern. As the duration of the Gemini flights increased, the corresponding increase in risk of disease prompted reducing the number of people to whom the crews were exposed before launch. Although no serious episodes took place during flight, Gemini crews did experience minor illnesses such as colds and influenza during the period before launch. During the Apollo program, concern increased over the possibility and consequences of infectious diseases, particularly with regard to the difficulty of completing a lunar landing should a crewmember become seriously ill during the mission. During preparations for Apollo-8, every crewmember suffered viral gastroenteritis during the preflight period. However, the recurrence 28 of the infection in one crewmember during flight greatly increased awareness of the need for more stringent preflight measures to protect astronaut health during missions. The Apollo-14 mission was the first to be conducted under a formal Health Stabilization Program for flight crews. The goal of this program was to eliminate in-flight health problems by minimizing or eliminating adverse alterations in the health of flight crews during the period immediately before launch.
