A pilot study has been conducted in 227 students in a primary school stiuated in the Dacca city. The study indicates that the height, weight of urban children has become a little improved since the Nutrition Survey of East Pakistan was done in 1962-64. A high percentage of enlarged tonsil and caries teeth were observed in the study group.

STUDY OBJECTIVE: Performance evaluation of a draw-over vaporizer with a nonrebreathing circuit during simulated adverse conditions. DESIGN: Open laboratory study. SETTING: University hospital laboratory. MATERIALS AND INTERVENTIONS: The output (%) of a temperature-compensated Ohmeda Cyprane PAC (portable anesthesia complete) draw-over vaporizer (Ohmeda, Madison, WI) using isoflurane attached to a nonrebreathing circuit was tested in the laboratory during manual ventilation under normal and simulated adverse conditions. The adverse conditions tested were high ambient temperature and static and dynamic positional variation. MEASUREMENTS AND MAIN RESULTS: The results show that the output bias of the PAC vaporizer has a generally consistent profile as tested, except when placed in the 180 degrees full-inversion or 90 degrees anterior-tilt position. We also conducted trials with the Penlon ventilator (Ohmeda, Abingdon, Oxford, U.K.) attached to the circuit at each of its input ports. Ventilation at one input port produced dangerously high airway pressures (within the circuit), thus supporting the manufacturer's recommendation against the use of this port for positive-pressure ventilation. Using the recommended port, the test lung was seen to inflate and deflate appropriately, but, surprisingly, no vapor output was detected by the agent monitor at any vaporizer setting when using the ventilator at the recommended port. CONCLUSION: Anesthetists should be aware of the pitfalls and possible problems that may be associated with this type of anesthetic delivery system.
Circulating proinsulin was assessed during a 75g OGTT in 55 pregnant women who fulfilled WHO criteria for impaired glucose tolerance before the 32nd gestational week. Proinsulin was assayed retrospectively using a two-site immunoradiometric assay and immunoreactive insulin by radioimmunoassay. Of the 55 women, 19 required insulin treatment in addition to diet later in pregnancy. Fasting proinsulin concentrations were significantly higher in the 19 women who later required insulin treatment compared with the 36 women treated with diet alone (3.4 +/- 0.7 vs 1.8 +/- 0.2 pmol l-1, p < 0.005). There was no difference between the treatment groups of 60 and 120 min proinsulin values during the OGTT. Fasting plasma glucose and immunoreactive insulin were similar in the insulin-treated and diet-treated women and remained similar during the OGTT. No women within the insulin-treated group had a fasting plasma proinsulin value < 1.1 pmol l-1 in contrast with 12 women in the diet-treated group (p = 0.0123). Ten of the 19 insulin-treated women had a fasting plasma proinsulin > 2.5 pmol l-1 compared with 8 of the 36 diet-treated women (p = 0.0346). Fasting proinsulin values early in pregnancy have prognostic implications in women with gestational diabetes.
