London: Arnold, 2001: 74-94 Gaping Gaping, or involuntary opening of the mouth, may occur as a focal dystonia of the motor trigeminal nerve, also known as Brueghel syn- drome after that artist’s painting De Gaper (“Yawning man,” ca. Afflicted individuals may also - 134 - Gegenhalten G demonstrate paroxysmal hyperpnea and upbeating nystagmus, sug- gesting a brainstem (possibly pontine) localization of pathology. The condition should be distinguished from other cranial dystonias with blepharospasm (Meige syndrome). Neurology 1996; 46: 1767-1769 Cross References Blepharospasm; Dystonia; Nystagmus Gaze-Evoked Phenomena A variety of symptoms have been reported to be evoked, on occasion, by alteration of the direction of gaze: ● Amaurosis: lesion, usually intraorbital, compressing central retinal artery ● Laughter ● Nystagmus: usually indicative of cerebellar lesion; may occur as a side-effect of medications; also convergence-retraction nystagmus on upgaze in dorsal midbrain (Parinaud’s) syndrome ● Phosphenes: increased mechanosensitivity in demyelinated optic nerve ● Segmental constriction of the pupil (Czarnecki’s sign) following aberrant regeneration of the oculomotor (III) nerve to the iris sphincter ● Tinnitus: may develop after resection of cerebellopontine angle tumors, may be due to abnormal interaction between vestibular and cochlear nuclei ● Vertigo Cross References Leopold NA. Journal of Neurology, Neurosurgery and Psychiatry 1977; 40: 815-817 Gaze Palsy Gaze palsy is a general term for any impairment or limitation in conjugate (yoked) eye movements. Preservation of the vestibulo-ocular reflexes may help dif- ferentiate supranuclear gaze palsies from nuclear/ infranuclear causes. Cross References Locked-in syndrome; Supranuclear gaze palsy; Vestibulo-ocular reflexes Gegenhalten Gegenhalten, or paratonia, or paratonic rigidity, is a resistance to pas- sive movement of a limb when changing its posture or position, which is evident in both flexor and extensor muscles (as in rigidity, but not spasticity), which seems to increase further with attempts to get the patient to relax, such that there is a resistance to any applied movement - 135 - G Gerstmann Syndrome (German: to counter, stand ones ground). However, this is not a form of impaired muscle relaxation akin to myotonia and paramyotonia. For instance, when lifting the legs by placing the hands under the knees, the legs may be held extended at the knees despite encouragement on the part of the examiner for the patient to flex the knees. Gegenhalten is a sign of bilateral frontal lobe dysfunction, espe- cially mesial cortex and superior convexity (premotor cortex, area 6). It is not uncommon in elderly individuals with diffuse frontal lobe cerebrovascular disease. Cross References Frontal release signs; Myotonia; Paramyotonia; Rigidity; Spasticity Gerstmann Syndrome The Gerstmann syndrome, or angular gyrus syndrome, consists of acalculia, agraphia (of central type), finger agnosia, and right-left dis- orientation; there may in addition be alexia and difficulty spelling words but these are not necessary parts of the syndrome. Gerstmann syndrome occurs with lesions of the angular gyrus and supramarginal gyrus in the posterior parietotemporal region of the dominant (usually left) hemisphere, for example infarction in the territory of the middle cerebral artery. All the signs comprising Gerstmann syndrome do fractionate or dissociate, i. Nonetheless the Gerstmann syndrome remains useful for the purposes of clinical localization.

London: Imperial College Press, 2003: 92-94 Cross References Acalculia; Agraphia; Alexia; Finger agnosia; Right-left disorientation Geste Antagoniste Geste antagoniste is a sensory “trick” which alleviates, and is character- istic of, dystonia. Geste antagoniste consists of a tactile or propriocep- tive stimulus, which is learned by the patient, which reduces or eliminates the dystonic posture. For example, touching the chin, face or neck may overcome torticollis (cervical dystonia), and singing may inhibit blepharospasm. They are almost ubiquitous in sufferers of cervical dystonia and have remarkable efficacy. The mechanism is unknown: although afferent feedback from the periphery may be relevant, it is also possible that concurrent motor output to generate the trick movement may be the key element, in which case the term “sensory trick” is a misnomer.

Infarction due to vertebral artery occlusion (occasionally poste- rior inferior cerebellar artery) or dissection is the most common cause of lateral medullary syndrome, although tumor, demyelination, and trauma are also recognized causes.

The term may be used to describe ipsilateral axial lateropulsion after cerebellar infarcts preventing patients from standing upright causing them to lean to toward the opposite side. Lateral medullary syndrome may be associated with lateropulsion of the eye toward the involved medulla, and there may also be lateropulsion of saccadic eye movements.

In the case of smoking antibiotic premedication for dental procedures buy 1000 mg ciprofloxacin visa, this occurred with the shift of focus to passive smoking in the late 1980s; in relation to CHD antibiotic that starts with l cheap ciprofloxacin 500 mg with mastercard, government promotion of ‘healthy eating’ began earlier but also became a major campaign in the late 1980s and in the Health of the Nation initiatives of the early 1990s; both the cervical and breast screening programmes were nationalised in 1987–88 bacteria mod 179 purchase ciprofloxacin visa. The state’s assumption of a leading role in health promotion inevitably changed the character of these initiatives. Once they had acquired a wider political and ideological role, their contribution to health became of secondary importance. At a time when politicians were preoccupied with the declining prestige of government, projecting an image of concern with health helped to shore up public 65 SCREENING approval. Successive governments recognised the potential of health as a means of establishing points of contact between the state and an increasingly atomised society, a trend which reached its apotheosis in NHS Direct, the 24-hour telephone advice line set up in 1999, claimed by Tony Blair as one of the greatest achievements of his first 1,000 days in office. Employers too recognised the potential of health promotion in managing relations with workers. In a perceptive study, Margaret May and Edward Brunsdon noted the shift in the 1980s away from traditional ‘occupational health’ concerns towards ‘new “wellness” interventions’, including medical ‘check-ups’, ‘health risk appraisal’, screening tests and preventive lifestyle advice (May, Brunsdon 1994). They characterised this as ‘a new form of employee control’, far beyond the familiar organisation of work, as the jurisdiction of the employers extended into workers’ private lives. They commented on the convergence of management theory and government health policy around the themes of personal responsibility. The proliferation of workplace smoking bans in the 1990s was another indication of the extension of managerial authority justified by concern for employee’s welfare. As health promotion assumed an ever greater profile, there was some divergence between the ways in which prevention strategies were presented to the public and how they were perceived within the private world of medicine. The politicians and the media wanted simple messages, soundbites, and doctors who took the lead in health promotion campaigns were happy to provide them—on the evils of passive smoking, the dangers of dairy products or the need for screening tests. Meanwhile, as we have seen, a high—and often increasing—level of scepticism came to prevail among medical experts about the value of all these interventions. In fact, in private, many doctors in all specialities are doubtful of the value of much of the work of health promotion. However, recognising the strength of the health promotion consensus, solidly backed by government funding, medical vested interests and compliant journalists, they think it best to keep their reservations to themselves. Indeed, as any of the sceptics who have spoken out could testify, the price of making private reservations about fashionable health promotion interventions public is high. The intellectual insecurity underlying the health promotion consensus is expressed in a dogmatic intolerance of criticism and intense hostility towards any dissident opinion. Anybody who ventures criticism of these policies—or has the temerity to publish research revealing their ineffectiveness—can 66 SCREENING expect a tirade of abuse and little prospect of academic advance- ment. A spirit of ‘not in front of the children’ governs debate as medical science is subordinated to political expediency. The second theme that emerges from our discussion of health promotion interventions is the resulting restriction on individual liberty. This is not so much a matter of direct compulsion, but of the oppressive effect—well expressed by Bridget Jones in her eponymous diary—of living in constant awareness of the need to count cigarettes, calories and units of alcohol (Fielding 1997). When I first received a ‘health risk assessment’ report resulting from the sort of encounter that so incensed Ruth Lea of the Institute of Directors in the account quoted above, I expected that it would provoke a similar response from many patients annoyed by the intrusive and impertinent character of the questions and the patronising style of the advice. The attitude of most people to such procedures appears to have shifted from an earlier bemusement or indifference (combined with some irritation at the amount of time wasted) to a more recent positive enthusiasm for intervention. This outlook extends to patients (invariably, in my experience, fit young men) whose friends have had the full medical, but whose own employers do not stretch to the (considerable) expense. They turn up at the surgery, declaring that they ‘need a complete check-up’. The popularity of the notion that healthy young people require regular medical maintenance marks the triumph of the ideology of health promotion.
Most repairs are done in association with ACL reconstruction and do not require the use of a fibrin clot bacteria bacillus purchase ciprofloxacin with visa. If the physician needs to repair an isolated tear antimicrobial silver gel buy ciprofloxacin with amex, the addition of a fibrin clot will improve the results infection you can get when pregnant order ciprofloxacin 250mg visa. To prepare the clot, the physi- cian will need a glass syringe and a glass rod to stir the blood to form a firm clot. The clot is then inserted under the meniscus at the meniscus synovial border. The fibrin clot may also be produced by curetting a portion of the notch to produce bleeding. If the ACL reconstruction is done, then bleeding will be produced by the notchplasty. Clinical Results Peter Kurzweil reported the following results at the Arthroscopy Asso- ciation of North America (AANA) fall course in San Diego: The Technique of the BioStinger Insertion 87 Figure 6. Hamstring Graft Reconstruction Techniques Albrecht-Olsen: 34 patients with a 21% failure rate. Kurzweil discussed his failures with repairs that used the bioabsorbable arrow. He found that two failures were the result of flexion injuries in the first 3 to 5 weeks. Three were the result of large peripheral bucket tears that were displaced at the time of diagnosis. Based on his experience, he recommends that there should be no accelerated rehabilitation; therefore, no flexion or squatting for four months. He also suggests that the physician combine the repair techniques of suture and arrows for large displaced bucket tears. Kurzweil also cycles the knee after the repair to make sure that the bucket tear does not dislocate again into the notch. He avoids the bioabsorbable devices in the red-on-red tears, in the popliteal tendon region, in small tight knees, and in large displaced bucket-handle tears. Summary Meniscus repair in a suitable patient with the appropriate tear is effica- cious. The use of the bioabsorbable devices should be used judiciously and in large tears in combination with sutures. Complications with the Use of the Bioabsorbable Fixators The use of bioabsorbable fixators may result in fixators that break and become loose in the joint. The head of the device may be prominent and damage the articular surface. To avoid this, the device must be coun- tersunk under the meniscal surface. The device may penetrate posteri- orly and injure the neurovascular structures. The physician should avoid this problem by using only the 10- and 13-mm devices. Otherwise, the device may not approximate the repair site adequately, and this can result in failure of the repair. Summary In young patients it is always preferable to try to repair the meniscus. The author uses a combination of inside out nonabsorbable sutures and absorbable meniscal arrows. The combination of vertical sutures in the middle of the meniscus, and bioabsorbable arrows in the posterior region is shown in Figure 6. The video on the CD includes a demonstration of the inside out, zone-specific technique of meniscus repair.

Burns School of Medicine, University of The first 2 years of his medical education were Hawaii, Honolulu. He completed his head of the Department of Neurological Surgery medical education at Rush Medical College (Uni- at the University of Chicago Medical School, versity of Chicago), graduating in the class of Albert M. Billing Hospital, and the University of 64 Who’s Who in Orthopedics Chicago Clinics in 1954–1955. Over the years, he has been a visiting professor at the University of Oregon Medical School, the University of South- ern California at Los Angeles, and Rush Medical College, The Rush Presbyterian–St. Cloward was a fellow of the American College of Surgeons and is certified by the American Board of Neurological Surgeons (1941). He was an honorary member of the Asian–Australasian Society of Neurologi- cal Surgeons and served as guest lecturer at the recent Sixth Congress in Hong Kong. Cloward had published 83 original articles in national and international medical journals on neurosurgical subjects and was the author of numerous monographs. He had also made three documentary surgical movies, filmed by the John Robert COBB famous Hollywood surgical motion-picture pho- tographer Billy Burke, on the subjects of lumbar 1903–1967 vertebral body fusion, anterior cervical fusion, and anterior cervical cordotomy. He had a long American heritage, member of the Mormon Church, was a playing one of his ancestors having come over on the member of the Honolulu Symphony Orchestra Mayflower. His father believed in discipline along (1926–1928), and for 1 year (1927) was a member with study and consequently sent him to the of the Royal Hawaiian Hotel Band in Honolulu. He began He is also a member of the Sons of the American his adult life without any clear conviction of his Revolution and the Sons of Utah Pioneers.

He went to sea many beautiful receptions in their beachfront at the age of 16 on a merchant steamer and spent estate at the tip of Diamond Head. He entered Brown University, where he majored in English literature and graduated with the degree of BA in 1925. He was on the swimming team and also on the wrestling team and he won his letter in cross- country running. His skill in swimming stood him in good stead, for he spent nine summers working as a lifeguard in the Rockaway Beach area and in this way earned enough each year to pay his college expenses. In his senior year he became converted to the idea of a medical career and had to rearrange his educational program because he had not enough science for acceptance in medical school. He made good this deficit by enrolling for a year at Harvard as a postgraduate student in bio- logical sciences, and he always maintained that this was the best method of preparation for the 65 Who’s Who in Orthopedics study of medicine.
