Two hundred and fifty patients with hemifacial spasm from the Movement Disorder Clinic, at Siriraj Hospital have been treated with botulinum toxin injection since January 1989 as a collaborating research project with Smith-Kettlewell Eye Research Institute in San Francisco. Each patient received 30 units in four injection sites over the hyperkinetic facial muscles. There were 169 female and 81 male patients, the sex ratio of female to male was 2.1:1. The mean age of all patients was 50.2 +/- 12.6 years with the range of 22 to 78 years. The majority of patients had been suffering for 3-10 years. The results of botulinum toxin injection were classified as excellent in 81.2 per cent, moderate improvement 10.0 per cent, mild improvement 6.8 per cent and no improvement or worse in 2.0 per cent. There were complications of mild transient facial weakness in 44 patients (17.6%) mild ptosis in 7 patients (2.8%) and excessive lacrimation in 1 patient (0.4%). The effect of botulinum toxin treatment lasted for 3-6 months duration. Botulinum toxin injection is a simple and effective out-patient treatment for patients with hemifacial spasm with no systemic side effects and minor transient local complications.

Patients with erythema multiforme (EM) often have chronic or recurring oral lesions that cause intense pain and interfere with a variety of functions including eating and speech. Previous studies suggest that levamisole restores to normal the function of phagocytes and T lymphocytes, and activates the inflammatory response. In our previous double-blind study 8 of 13 patients with EM had a decrease in severity and frequency of attacks. The purpose of this open prospective study was to evaluate short-term and long-term clinical efficacy of levamisole in patients with mucocutaneous EM. Thirty-nine patients with mucocutaneous EM seen in the Oral Medicine Clinic, School of Dentistry, University of California-San Francisco, comprised our study group. Levamisole was used alone in 17 patients or in combination with prednisone in 22 patients and was given as a single dose of 150 mg/day for 3 consecutive days. Thirty-one patients showed a complete response from levamisole (alone in 13 and in combination with prednisone in 18). Four showed a partial response of signs and symptoms, and four others had no benefits from levamisole whether alone or in combination. The most common side effects from levamisole were skin rash, tiredness, weakness, myalgia, taste change, and insomnia.

Since 1973, fourteen free muscle transfers for functional upper limb reconstruction have been performed in twelve patients at the Ralph K. Davies Medical Center in San Francisco. All of the patients in this series had lost finger flexion, extension, and/or thumb opposition and were not candidates for simpler methods of reconstruction because of weakness or traumatic loss of balancing musculature. The 12 patients have been followed for one to 9 years. All muscles were successfully transferred without flap loss. Evaluation of the EMG data has shown evidence of reinnervation beginning at approximately two months with fibrillation potentials decreasing and recruitment of increasing numbers of motor units over two to three years. Eleven of the 14 muscles attained movement against resistance; two had movement against gravity and one regained only a flicker of motion. In our experience, the use of free muscle transplantation to restore function is not only technically feasible, but moreover, has resulted in a relatively high degree of patient satisfaction.

Investigations of schistosomiasis mansoni in 218 Yemeni agricultural workers in the San Joaquin Valley of California revealed a prevalence of 56%. In those infected, quantitative egg counts performed by the Kato thick smear method revealed that 57% had light infections (1-100 eggs/g), 27% moderate infections (101-400 eggs/g), and 16% heavy infections (greater than 400 eggs/g; mean--918 eggs/g). The Yemeni had been migrating to the USA for the past 20 years, a period in which the prevalence of schistosomiasis had remained constant in the Yemen. The prevalence of schistosomiasis in those who had been away from Yemen for less than 5 years was 59% with a mean egg output of 236 eggs/g, but in those away for more than 5 years (up to 20 years) it was 32% with a mean egg output of 75% eggs/g. This is in spite of the fact that 75% of the latter had returned to Yemen for short visits. Statistical analysis by the Fisher's exact probability test revealed a significantly lower egg output in those away from Yemen more than 5 years. On the basis of these findings the mean life span of the Yemen strain of Schistosoma mansoni in man was estimated to be between 5 and 10 years. The presence of disease was assessed in this population by traditional medical means without prior knowledge of the status of the infection in the individuals examined. Under these circumstances, there were no differences in symptoms such as weakness, diarrhea and abdominal pain among the uninfected proportion of the population, total infected group and a small subgroup of those most heavily infected. None of the patients had hepatomegaly and only two had splenomegaly--one lightly and the other heavily infected. Because of the toxicity of antischistosomal drugs and the lack of treatment facilities only the 22 most heavily infected (greater than 200 eggs/g) of the 122 individuals with schistosomiasis mansoni were treated with niridazole. In addition the two individuals with splenomegaly were treated with antimony dimercaptosuccinate. Side effects, though common, were not severe. Although follow-up in this migrant population was poor the nine patients examined 3 to 7 months after treatment showed a mean decrease in egg output of 97%.

A female bonobo (Pan paniscus) born at the San Diego Zoo exhibited inability to nurse and progressive weakness plus multiple congenital abnormalities including aural canal atresia and stenosis, malformed auricles, clenched hands, lordosis, agenesis of the caudal vertebra and cardiac abnormalities. Chromosome analysis identified the bonobo as being trisomic for chromosome 17, the homolog of human chromosome 18. Genotyping with human microsatellites suggested the extra chromosome was maternal in origin. In addition, a male lowland gorilla (Gorilla gorilla gorilla), also born at the zoo, exhibited postnatal growth retardation, facial dysmorphisms and small hands with short fingers. Karyotype analysis revealed the gorilla carried a deletion of the distal q arm of chromosome 3, the homolog of human chromosome 4. The phenotypic and karyotypic abnormalities found in the bonobo and gorilla were consistent with the characteristics of human trisomy 18 and human deletion 4q syndrome, respectively.

Dr. Cesar T. San Pedro, the director of the company clinic at Dole Philippines plantation in South Cotabato in Region 11, has been pressing the management to initiate a comprehensive family planning programs for their 10,000 workers. Pedro wants the Ministry of Labor and Employment (MOLE) to enforce its population program. The situation at Dole is one that requires an arbiter. Since 1977, there has not been a Population/Family Planning Officer (PFPO) for the area, and it is not possible to monitor closely if the qualified firms are following the labor code and providing family planning services to their employees. Susan B. Dedel, executive director of the PFPO, has reported that the office has sought to endear its program to the private sector by showing that family planning is also profitable for the firm. This "soft-sell" approach has been the hallmark of the MOLE-PFPO since it began in 1975 as a joint project of the Commission on Population (POPCOM), United Nations Fund for Population Activities (UNFPA), and International Labor Organization (ILO). Some critics have argued that this liberal style of implementation is short-selling the program. They point out that the Labor Code of 1973 enforces all establishments with at least 200 employees to have a free in-plant family planning program which includes clinic care, paid motivators, and volunteer population workers. The critics seem, at 1st glance, to have the statistics on their side. In its 5 years of operation, the PFPO has convinced only 137,000 workers to accept family planning. This is quite low, since of the 1.2 million employed by the covered firms, 800,000 are eligible for the MOLE program. Much of the weakness of the implementation is said to be due to the slow activation of the Labor-Management Coordinating Committees (LMCC). The critics maintain that because of the liberal enforcement of Department Order No. 9, the recalcitrant firms see no reason to comply. Dedel claims that the program is on the right track. Hamlish Richards, chief of ILO's population and labor policies branch, has high praise for the program. Over the years the ILO has awarded fellowships to 19 labor ministry officials from Asia and Africa to learn from Dedel and her staff. What is most impressive is PFPO's training component. The country's bigger establishments have already implemented the PFPO concepts, and the programs of these companies are reviewed. Last year PFPO entered into an agreement with the Population Center Foundation and POPCOM Region 11 to test the viability of the use of incentives. 6 companies agreed to try out this approach.

In this paper an analysis is provided on: what we know, what we need to know, and what we need to do, to further our understanding of the relationships between tropospheric ozone (O(3)), global climate change and forest responses. The relationships between global geographic distributions of forest ecosystems and potential geographic regions of high photochemical smog by the year 2025 AD are described. While the emphasis is on the effects of tropospheric O(3) on forest ecosystems, discussion is presented to understand such effects in the context of global climate change. One particular strong point of this paper is the audit of published surface O(3) data by photochemical smog region that reveals important forest/woodland geographic regions where little or no O(3) data exist even though the potential threat to forests in those regions appears to be large. The concepts and considerations relevant to the examination of ecosystem responses as a whole, rather than simply tree stands alone are reviewed. A brief argument is provided to stimulate the modification of the concept of simple cause and effect relationships in viewing total ecosystems. Our knowledge of O(3) exposure and its effects on the energy, nutrient and hydrological flow within the ecosystem are described. Modeling strategies for such systems are reviewed. A discussion of responses of forests to potential multiple climatic changes is provided. An important concept in this paper is that changes in water exchange processes throughout the hydrological cycle can be used as early warning indicators of forest responses to O(3). Another strength of this paper is the integration of information on structural and functional processes of ecosystems and their responses to O(3). An admitted weakness of this analysis is that the information on integrated ecosystem responses is based overwhelmingly on the San Bernardino Forest ecosystem research program of the 1970s because of a lack of similar studies. In the final analysis, it is recommended that systems ecology be applied in examining the joint effects of O(3), carbon dioxide and ultraviolet-B radiation on forest ecosystems.

A retrospective study was performed on 200 randomly selected cases of inflammatory myopathy in dogs from diagnostic muscle biopsies received at the Comparative Neuromuscular Laboratory, University of California, San Diego. The most common clinical signs in dogs diagnosed with an inflammatory myopathy were generalized weakness, stilted gait, dysphagia, masticatory or generalized muscle atrophy, inability to open the jaw, megaesophagus, and dysphonia. Myalgia was rarely described. Age of onset ranged from 0.25 to 14 years. Genders were equally represented. Breed distribution approximated the 2002 American Kennel Club registration statistics (r = .85) with the notable exception of Boxers and Newfoundlands. From the results of muscle biopsies, clinical signs, and presence or absence of antibodies against type 2M fibers, dogs were classified as a generalized inflammatory myopathy (gIM)--including immune-mediated polymyositis; infectious and preneoplastic myositis; and, rarely, dermatomyositislike or overlap syndromes or unclassified myositis-or a focal inflammatory myopathy (flM)--including masticatory muscle and extraocular myositis. Average creatine kinase (CK) and aspartate aminotransferase (AST) concentrations in gIMs were significantly higher than those with fIMs (P < .05). Neoplasia developed in 12 of 200 dogs within 12 months of diagnosis of polymyositis, with lymphoma diagnosed in 6 of 32 Boxers. Inflammatory myopathy was associated with antibody titers against infectious diseases in 38 dogs. Neospora caninum and Hepatozoon americanum cysts were found in tissues of 2 dogs not serologically tested. Antibodies against an unidentified sarcolemmal antigen were found in 9 of 19 Newfoundlands with polymyositis. The spectrum of canine inflammatory myopathies can be broad, with infectious etiologies relatively common, and can include preneoplastic and uncharacterized syndromes.

How do neighborhoods affect the health of residents? We propose that the impact of neighborhood disorder on self-reported health is mediated by psychological and physiological distress. We hypothesize a stress process in which chronic stressors in the environment give rise to a psychological and physiological stress response that ultimately affects health. The exogenous variable of interest is the neighborhood where disadvantaged persons live, which may expose them to chronic stressors in the form of crime, trouble, harassment, and other potentially distressing signs of disorder and decay. The mediator is the stress response that occurs in the body and brain. Of interest here is a psychological stress response in the form of fearful anxiety and depression, and a physiological stress response in the form of signs and symptoms of autonomic arousal, such as dizziness, chest pains, trouble breathing, nausea, upset stomach, and weakness. The outcome is poor health. This model is supported using data from the Welfare, Children, and Families project, a sample of 2,402 disadvantaged women in disadvantaged neighborhoods in Chicago, Boston, and San Antonio.

The authors report a case of a human-habituated mountain gorilla, Alvila, resident at the San Diego Zoo, who was found to have a herniated intervertebral lumbar disc after being attacked by the gorilla troop's silverback male gorilla. Ultimately, the gorilla required surgical intervention for her disease and made a full recovery. To our knowledge, this is the only known case of spine surgery. A 36-year-old female human-habituated mountain gorilla (Gorilla beringei beringei), resident at the San Diego Zoo, was noticed by caregivers to walk with a substantial limp after being attacked by the gorilla troop's silverback male gorilla. Magnetic resonance (MR) imaging of her lumbar spine revealed a large herniated disk at the L1-2 level on the right. This finding appeared to correlate well with the gorilla's symptoms. The gorilla underwent a lumbar diskectomy under loupe. Post-operatively the gorilla did very well. The right leg weakness was immediately improved post-operatively. The gorilla continued to "crutch walk" initially, swinging on the upper extremities and not bearing weight on the lowers. However, by 2 weeks the limp was no longer noticeable to the zoo caregivers. The wound healed well and there was no evidence of wound infection or CSF leak. The gorilla was reunited with her troop and has reintegrated well socially. With 10 months of follow-up, the gorilla continues to do well. This is the only known case of spine surgery in a gorilla. For best surgical results, one needs to consider the similarities and differences between the gorilla and human vertebral anatomy. We believe that careful pre-operative planning contributed to the good early post-operative result. Ultimate assessment of the long-term outcome will require additional follow-up.
