Management of liver injuries in Zaria, Nigeria

The records of 37 patients with liver injuries operated upon at the Ahmadu Bello University Teaching Hospital, Zaria, Nigeria from 1976 to 1987 were reviewed. There were 31 males and 6 females with a mean age of 22 years. Sixty-two per cent were due to blunt injury from road traffic accidents, 14 per cent were due to gunshot wounds and 5 per cent due to stab wounds as a result of assaults. Treatment with simple suture and drainage sufficed in 49 per cent; only 16 per cent required resection, packing and drainage. Associated injuries included long bone fractures and chest trauma. The most common complication was sepsis and the overall mortality was 19 per cent.     

Detecting pediatric autoimmune neuropsychiatric disorders associated with streptococcus in children with obsessive-compulsive disorder and tics.

BACKGROUND: A subgroup of children with obsessive-compulsive and tic disorders are proposed to have an infectious trigger. The purpose of this study was to investigate the relationship between group A streptococcal titers and symptom fluctuations in children with a clinical course resembling that described for pediatric autoimmune neuropsychiatric disorders associated with streptococcus. METHODS: Twenty-five children with obsessive-compulsive disorder and/or tic disorder were evaluated for neuropsychiatric severity and group A streptococcal antibody titers (streptolysin O, deoxyribonuclease B, and carbohydrate A) at 6-week intervals for > or = six consecutive evaluations (total visits=277). RESULTS: Children with large symptom fluctuations (n=15) were compared with children without dramatic fluctuations (n=10). Co-movements of obsessive-compulsive/tic severity and group A streptococcal antibodies were assessed. In subjects with large symptom changes, positive correlations were found between streptococcal titers and obsessive-compulsive severity rating changes (p=.0130). These subjects were also more likely to have elevated group A streptococcal titers during the majority of observations (p=.001). Tic symptom exacerbations occurred more often in the fall/winter months than spring/summer months (p=.03). CONCLUSIONS: Patients with marked obsessive-compulsive/tic symptom changes may be characterized by streptococcal titer elevations and exhibit evidence of seasonal tic exacerbations.     

Three Cases of Comprehensive Dietary Therapy and Pharmacotherapy of Patients with Complex Obesity-related Diseases

The effect of weight loss with anorectic medications on sleep apnea, non-insulin-dependent diabetes, and steatohepatitis is illustrated in three cases from practice in a clinical nutrition setting. Prevention of obesity, a chronic disorder, is preferable, but when obesity becomes a major obstacle in the care of patients with respiratory, cardiovascular, and metabolic disorders and osteoarthritis, an intense course of weight reduction using anorectic medications under medical and dietetic guidance is essential for patients' survival and reduction of medical cost.     

A practical profile of integrated safety assessment of near-surface disposal of radwaste at PINSTECH.

Near-surface or shallow land disposal of radioactive waste has been the primary practice at the Pakistan Institute of Nuclear Science and Technology (PINSTECH). The adopted choice of this mode of disposal has been based on a study of the site and the quality and quantity of waste generated at the 5 MW reactor with HEU fuel. Specific measures regarding the radiation safety of the workers and environmental protection have been adopted. The waste disposal operations are conducted to meet local regulatory requirements, IAEA recommendations and internationally endorsed principles such as ALARA (as low as reasonably achievable - economic, social and other relevant factors being considered). The data obtained through the years of operational and management experience have manifested the robustness of the disposal system and reliability of the disposal criterion, and have also served to further refine the latter. Consequently, confidence in the current shallow-land-burial practices has increased. Radiological safety of these practices has been assessed by addressing different aspects of the safety and disposal system. These parameters, as indices of a non-exclusive and operational safety model, are presented.     

Hearing acuity in post spinal analgesia period

100 cases of either sex 96 males and 4 females in their mean age group of 45 year ± 14.51 standard deviation were selected for this study to analyse the Hearing Acuity in the post spinal analgesia period during a period of eight months in the E.N.T department of the J.N. Medical College A.M.U. Aligarh. The size of the needle used for spinal analgesia was 22G and the equipment for Audiometry was the pure tone Audiometer. Pure tone Audiometry was done pre-operatively and then on the 1st, 3rd, 5th and 12th subsequent post-operative days and then after six months. It was found that 12% of the patients showed incidence of mild hearing loss. However, the loss was transient, reversible, within low frequency range (250, 500, 1000 Hz), and no patient suffered from any permanent hearing loss.
