Laboratory experiments on the control of cyclops transmitting guinea worm.

Infection with the guinea worm (Dracunculus medinensis) affects millions of people living in rural areas in certain parts of the world. Usually, the standard of living is low and elaborate control measures would not be feasible. In this study, various insecticidal and molluscicidal compounds were tested in the laboratory for their toxicity to the intermediate hosts, namely, various species of cyclops, which often live in sources of potable water, such as step-wells, cisterns and ponds. Cheapness, low toxicity to mammals and ease of application, in conjunction with effectiveness against cyclops, are primary requisites for any compound accepted for widespread use. Abate, an insecticide, has been shown to be particularly promising in these respects. The timing and mode of application of compounds toxic to cyclops in various endemic regions are discussed.

Virtual elimination of necrotising enterocolitis for 5 years - reasons?

UNLABELLED: A standardised feeding regimen was adopted in 1997 for guiding enteral feeding of neonates <32 weeks' gestation during clinical trials (18 months each) involving erythromycin (n=73) as a prokinetic and carboxymethylcellulose (n=70) as a laxative as well as for during 2 years (n=155) without any trials. Most aspects of the feeding regimen (e.g., milk increments-total volume/day, use of breast milk by choice, etc) were not significantly different from current practices. RESULTS: 298 neonates <32 weeks' gestation (<28 weeks; n=78) were enterally fed during the 5 years. Their demographic characteristics and median (interquartile) age in days at starting (AST) and days to reach full enteral feeds (FFT) of 150 ml/kg/day were not significantly different during these 5 years: [AST: 5 (3-7.5)], [FFT: 4 (3-7)] Only one case of definite NEC (> or =Stage II) occurred during the 5 years. The time to reach full feeds was also reduced by over 54% (including for neonates <28 weeks gestation) compared with a historical cohort. CONCLUSION: Sustained reduction in the time to reach full feeds with virtual elimination of > or =Stage II NEC for 5 years indicates continued benefits of a standardised feeding regimen as a simple preventive strategy to prevent NEC. Whether our specific policy of no enteral feeds in presence of hemodynamic instability associated with PDA requiring indomethacin, and/or sepsis played a role in achieving the significant results needs controlled trials.

[Acute renal failure in children. Study of 35 patients].

The medical care of children with acute renal failure and the necessity of the substituting the renal functions has dramatically modified over the past 15 years. The study has been conducted retrospectively on 35 children diagnosed with acute renal failure (ARF), for analyzing the etiological spectrum, the evolutionary patterns and the influence factors of the ARF evolution. The following parameters have been taken into consideration: ARF etiology, hTA/HTA, oliguria, level of serum creatinine, the type of treatment (renal substitution by hemodialysis, peritoneal dialysis, or conservative treatment). The ARF etiology is dominated by the sepsis (31.4%) and by the hemolytic and uremic syndrome (17.1%). The treatment applied was conservative in 48.5% of the cases; 51.50% of the patients were in critical state and required extrarenal substitution by hemodialysis--42.8%--and peritoneal dialysis--8.5%. Global mortality is reduced (22.8%), but in the dialysed patients it is of 44.44%. The main death causes were: severe hepatic failure, oncological diseases, severe neurological damage and hemodynamic damages. In conclusion, the ARF prognosis in children is influenced by the comorbidity states. Dialysis has improved the therapeutic results in the currently presented lot, the death causes being extrarenal.

[Treatment of varicose external saphenous vein by ambulatory phlebectomy].

In 1972, the French Society of Phlebology undertook a study of the treatment of the varicose S.S. vein which revealed an avalanche of problems concerning both surgery and sclerosing injections. Since 1960, there have been such advances in out-patient phlebectomy that it enables combination of the efficacy of surgery with the benign nature of sclerosing injections. It has proved possible to avoid the only true risk of out-patient phlebectomy (damage to the lateral saphenous nerve) by proscribing the use of a hook on the main S.S. and accessing it via a collateral.

[Ataxic hemiparesis due to a cerebellar lacuna].

The authors report a case of ataxic hemiparesis (dysarthria-clumsy hand syndrome plus crural hemiparesis with homolateral ataxia), secondary to a single cerebellar lacuna (CT scan), in a left rostral para-vermian position in the vicinity of the peduncle and secondary to arterial hypertension. They discuss the nosological aspects of this recently established entity and the origin of particularly severe and persistent dysphagia in their case (cerebellar dysphagia?)
