OBJECTIVE: To evaluate physicians' recognition of possible ethanol-related complications in trauma patients, and to compare benzodiazepine requirements in patients with positive and negative blood-ethanol concentrations. DESIGN: Retrospective investigation. SETTING: University medical center (level I trauma center). PATIENTS: One hundred thirty-one trauma patients more than 18 years of age who were admitted for at least 24 hours. OUTCOME MEASURES: (1) Physicians' recognition of ethanol (EtOH) as a potential factor complicating patient recovery in trauma patients admitted with positive blood-EtOH concentrations. (2) The amount of benzodiazepines administered to trauma patients with positive EtOH-blood concentrations compared to trauma patients with no detectable EtOH in their blood. RESULTS: The presence of EtOH in the blood or the potential for EtOH withdrawal was mentioned in the progress notes of approximately one fourth of the patients with positive blood-EtOH concentrations. Thiamine was administered in 8.2% of patients with EtOH-related injuries. Benzodiazepine requirements were significantly higher in patients with positive versus negative blood-EtOH concentrations. CONCLUSIONS: Prompt recognition and charting of suspected ethanol abuse is recommended, in conjunction with prompt administration of thiamine. It should be anticipated that patients with positive blood-ethanol concentrations will require higher doses of benzodiazepines compared to trauma patients without ethanol-related injuries.

Angiotensin converting enzyme in the testis and epididymis of mammals.

Angiotensin converting enzyme (ACE) activity has been reported in testis and epididymis of seven different animal species. Among all the species, the mouse testis and epididymis showed the highest converting enzyme activity followed by rat testis and epididymis. The lowest activity was detected in buffalo testis and rabbit epididymis. Most of the testicular enzyme was found concentrated in the 107,00 X g sediment while the epididymal enzyme was equally distributed between sediment and supernatant. ACE levels of different regions of the rat testis and epididymis was analyzed. The gradient of ACE was found increasing from caput to cauda. A major fraction of testicular and epididymal ACE activity was found in their respective fluid. ACE appeared only in mature rats, rabbits and mice testis and epididymis. Sexually stimulated rabbits showed significant ACE increase in the testis. In vitro characterization studies were conducted.

Androgen dependence of testicular and epididymal angiotensin converting enzyme.

Treatment with cadmium chloride (CdCl2) and cyproterone acetate (CA) depressed angiotensin converting enzyme (ACE) activity significantly in testes and epididymal regions of the adult rats compared to the corresponding untreated controls. Exogenous testosterone to CA-treated rats significantly increased the enzyme activity both in the testes and epididymis, the effect in the latter being very significant comparable to CA-treated and untreated controls. Testosterone failed to induce ACE activity in the testes and caput epididymis of 30 day-old immature rats, but the enzyme activity was detected in corpus and cauda epididymis. Our findings indicate that ACE activity in the testicular complex is possibly linked with androgen and is concerned with spermatogenesis and sperm maturation.

Dermatoglyphics in nasobronchial allergic disorders.

Fifty persons having nasobronchial allergy diagnosed by a positive skin test were compared with age and sex matched normal individuals for dermatoglyphic palmer patterns. The palmer prints were obtained on white art paper using Kores duplicating ink. In female patients, total number of whorls was less, more so on digit IV of left hand. Digit V of right hand had low frequency of ulnar loops, the d-t ridge count was low. In male patients, ulnar loops were less frequent on digit III of right hand. Total finger ridge count was less in both sexes. High frequency of arches was observed in female patients and in total. Digit V of left hand in females and in total patients revealed high frequency of arches. a-b ridge count was high in males and in total patients.

Efficacy and tolerability of Ketotifen in Nepalese asthmatic children: a clinical study.

OBJECTIVE: To assess the efficacy of Ketotifen in asthmatic children and to record its adverse effects, if any. DESIGN: Prospective clinical trial. SETTING: Pediatric asthma follow up clinic of a teaching hospital. PARTICIPANTS: 23 asthmatic children between 3 and 15 years; 100% completed the trial on full protocol. INTERVENTIONS: Ketotifen 1mg (adjusted according to body weight, 50 mcg/kg/dose) orally twice daily for 9 months. MAIN OUTCOME MEASURES PRIMARY OUTCOME: Decrease in frequency of asthmatic attacks and severity of exacerbations with improvements in peak expiratory flow rates (PEFR). Other measures included decrease in bronchodilator requirement, steroid doses and parental perception regarding patient quality of life. RESULTS: 34.78% children were symptom free by the end of 2nd 3 months and 65.21% had no further attack by the end of 3rd 3 months of Ketotifen prophylaxis. Those children with activity and sleep 'affected' (8.69%) and 'may be affected' (30.43%) together improved to 'may be affected' group (21.73%) by the end of 2nd 3 months and further reduced to 8.69% by the conclusion of 3rd 3 months. The duration of exacerbations was reduced in the remaining cases. Variability of PEFR decreased from 26.08% to 8.69% of children after the 3rd 3 months of Ketotifen prophylaxis. No significant adverse effect of therapy was observed during the study. CONCLUSION: Oral Ketotifen is effective and well tolerated for use in prophylactic treatment of bronchial asthma in children.
