Abstract
This study was designed to evaluate the sensitivity and specificity of abdominal ultrasonography as a diagnostic modality in a large series of children who presented with possible appendicitis. From August 1990 to July 1994, 452 children (203 boys, 249 girls) with an average age of 11 years (range, 1 to 20 years) underwent graded compression ultrasonography of the right lower quadrant of the abdomen for the evaluation of possible appendicitis. In the first 18 months of the study all patients with the possible diagnosis of appendicitis (group I; 180 patients) had abdominal ultrasonography after members of the surgical team evaluated and documented their findings in the medical record. In the second study period (30 months), abdominal ultrasonography was recommended only when the clinical diagnosis of acute appendicitis was equivocal (group II; 272 patients). Abdominal ultrasonography was performed using the graded compression technique with a 5.0-MHz linear array transducer. A positive ultrasound study for appendicitis was defined as the presence of an enlarged noncompressible appendix with an outer wall to outer wall diameter of greater than 6 mm, the presence of a complex mass, or the presence of an appendicolith. The sonographic data were correlated with surgical and pathological findings. Appendicitis was confirmed in 112 of the 452 cases. In 17 of these, the appendix was perforated. In the overall group of 452 children, abdominal ultrasonography had a sensitivity of 90%, specificity of 96%, and accuracy of 95%. There was no significant morbidity in the 11 patients with a false-negative study result. All 11 patients had an uncomplicated appendectomy. There were 11 false-positive results; 10 of these patients had a negative laparotomy result (negative laparatomy rate, 8.9%). For the two groups, the sensitivity and specificity of ultrasonography in the diagnosis of appendicitis were equivalent (group 1: 88% sensitivity, 96% specificity; group 2: 92% sensitivity, 97% specificity). On the basis of the high sensitivity and specificity rates, ultrasonography of the appendix can be a useful adjunct to standard examination in the diagnosis of acute appendicitis.

Abstract
We reviewed retrospectively the incidence of complications encountered with two different umbilical artery catheters (UACs): a silicone-rubber end-hole catheter and an electrode-tipped, side-hole catheter for continuous, invasive monitoring of arterial oxygen tension (PaO2). During calendar year 1989, there were 457 admissions to the neonatal intensive care unit: 168 patients had placement of a UAC. Two of these were admitted only briefly for cardiac catheterization and were eliminated from analysis. One patient had both types of catheters placed sequentially. Thus the data on 166 patients with 51 PaO2 monitors and 116 silicone-rubber UACs were evaluated. The patients who had a PaO2 monitor UAC had a lower mean birth weight than those in the other group (1621 +/- 1043 gm vs 1972 +/- 1048 gm; p = 0.0473). The catheter life span was not different between the groups, with a range of 1 to 16 days for PaO2 monitors and 1 to 27 days for silicone-rubber UACs. Inability to withdraw blood, poor blood pressure tracing, or both conditions resulted in catheter removal for 5 of 51 PaO2 monitor UACs and 4 of 116 end-hole UACs. The incidence of these problems did not differ significantly between the two groups. There were no cases of thromboembolic complications in the patients who had a PaO2 monitor UAC, whereas two of the silicone-rubber UACs were removed because of perfusion problems in the lower limbs, which resolved with decannulation. We conclude that the use of the PaO2 monitor UAC allows for continuous, invasive monitoring of PaO2 without any significant increase in risk compared with that for the silicone-rubber end-hole UAC.

Abstract
Reliable vascular access can be problematic in sick low-birth-weight neonates. Umbilical venous catheters are one form of vascular access that can be used in this population. A retrospective review of experience with umbilical venous catheters in our neonatal intensive care unit from January 1989 through December 1991 was conducted. This included 128 patients: 70 with single-lumen (Gesco Umbilicath II) and 58 with double-lumen (Becton-Dickinson Careflow) catheters. Birth weight, gestational age, catheter life span, complications, and number of punctures for peripheral intravenous lines were analyzed. The mean birth weight, gestational age, and catheter life span did not differ significantly between catheter types. The incidence of catheter-related sepsis did not differ significantly (two single-lumen, three double-lumen) and occurred only in neonates with a catheter life span greater than 10 days. The number of intravenous punctures was significantly decreased in those neonates with double-lumen umbilical venous catheters (p < 0.0001). We conclude that in sick low-birth-weight infants the use of double-lumen umbilical venous catheters entails no greater risk than the use of a single-lumen umbilical venous catheter and may reduce iatrogenic stress associated with the starting of peripheral intravenous lines.

Abstract
Vasectomy acceptance has been declining in India during the past 20 years. Even if the risk of prostate cancer is marginally higher in vasectomized men, this risk in India has to be assessed against the immediate safety and other possible long-term benefits of this procedure. The Indian Council of Medical Research has launched a case-control study, which is unlikely to be time-consuming or beyond the available means and resources, in order to obtain definitive data on this problem. Meanwhile, vasectomy remains an excellent procedure for the couple seeking permanent methods of contraception, and specific efforts to promote its acceptance must continue in India.

Abstract
Breastfeeding has been considered the best mode of feeding the infant. In traditional countries like India, it has been the tradition among poor income groups of women and the universal adage breast feed as long as possible goes uncontested. However, the appropriate age at which supplementation should start is replete with controversy and varies between as early as 3-6 months. While the debate on when should supplementation be started continues, it is also important to know if the nutritional benefit is expressed in terms of growth of the infant, under the existing unhygienic conditions. This study was therefore undertaken.

Abstract
OBJECTIVE To describe the epidemiology of patients with AIDS in Vellore region, Southern India. DESIGN AND METHODS Sixty-one patients with AIDS were diagnosed and treated between July 1987 and June 1992. Information on their demographic characteristics and probable modes of acquiring HIV infection was collected at interviews with them and their spouses. RESULTS There was a progressive increase in the number of patients seen over the 5 years. The mean ages of the 51 men and the 10 women were 33 and 29 years, respectively. Of the 44 patients from our district (population, 5 million), 28 were from Vellore town and 10 from rural areas. Forty-seven (92%) men had frequently used prostitutes. Of the women, four were prostitutes, one had had multiple sex partners and five had not had extramarital sexual contact. One man and one woman had no other risk factor except blood transfusion. Thirty-one (51%) patients had died by August 1992. CONCLUSION The AIDS epidemic in this region is in its early ascending phase, with a doubling time of approximately 1 year. Most men with AIDS were infected by heterosexual contact with prostitutes, while some women were prostitutes themselves. Together with the male-to-female ratio of 5:1, these results suggest that the male population at risk has sex with a much smaller population of female prostitutes, constituting the major chain of transmission. HIV infection is occurring in both urban and rural populations.

Abstract
We report on a liveborn premature male with trisomy 22 who had multiple congenital anomalies, including congenital diaphragmatic hernia and absence of corpus callosum. He died of pulmonary hypoplasia associated with diaphragmatic hernia within 12 hours of age. Chromosome analysis by multiple banding techniques based on lymphocyte culture confirmed that he had trisomy 22. This may be the first report of congenital diaphragmatic hernia and isolated absence of corpus callosum associated with trisomy 22.

Abstract
Chemotherapy studies were undertaken on 180 children, aged between 1 and 12 years, with tuberculous meningitis. They received therapy for 12 months. As approximately one-half of the patients came from outside Madras city, retrieval action was not possible in all cases of default. Despite this, a high rate of compliance and punctuality was achieved as a result of initial and periodic motivation. This report highlights the role and importance of motivation in the prevention of default and the retrieval of defaulters during the treatment of children with tuberculous meningitis.

Abstract
Continuous monitoring methods have shown changes of oxygenation in neonates during various procedures. However, actual changes in blood gases during vascular punctures have not been reported. We studied the effect of vascular puncture on arterial blood gases during routine venipuncture in 17 neonates who had indwelling arterial catheters. Arterial blood gases were analyzed before, during, and following recovery from venipuncture. Ventilator settings were not changed during the study, though oxygen concentration (FiO2) was adjusted as indicated by continuous PO2 or saturation monitors. During venipuncture, there was a significant fall in PaCO2 from 38 +/- 5 to 32 +/- 7 mmHg (P less than 0.0001) and in PaO2 from 75 +/- 21 to 58 +/- 23 mmHg (P less than 0.0001). Following venipuncture, both values returned to baseline. The results of this study imply that blood gases obtained by intermittent arterial sticks may provide data that do not accurately reflect the neonates' respiratory status.

Abstract
This report gives the findings of long-term follow-up (4 1/2-8 years) of 119 children who recovered from tuberculous meningitis. Of these, 17 patients died (10 due to severe tuberculous meningitis sequelae and 7 due to non-tuberculous causes) and 2 could not be traced. Of the remaining 100 patients for whom information was available, 47 (47%) made a complete recovery, while 53 (53%) had neurological sequelae--2 (2%) had severe, 39 (39%) moderate and 12 (12%) mild sequelae. There were no relapses during the 4 1/2-8 year period, indicating that regular treatment for 12 months may be adequate.

Abstract
In 152 cases of chronic myeloid leukemia (CML) (actuarial median survival [MS], 59.2 months), the statistical relation of individual parameters with survival was studied to ascertain their prognostic value. The following parameters were found to be unrelated to the survival: age, sex, duration of symptoms, sternal bone tenderness, degree of hepatomegaly, level of hemoglobin, and leukocyte and platelet counts at the time of diagnosis. Splenomegaly of less than 10 cm and duration of first remission of 6 months or more were associated with significantly longer survival (MS, 70.5 and 68.5 months, respectively) as compared to bigger spleen size and duration of remission of less than 6 months (MS, 50.5 and 26 months; P less than 0.01 and P less than 0.05, respectively). The most significant prognostic parameter was the time required to achieve first remission. MS was 70 months in patients who achieved first remission in 2 months or less; it was 23.5 months in the remaining patients. This difference was statistically highly significant (P less than 0.001).

Abstract
Results are presented of the incidence of hepatitis, nearly always with jaundice, among 1686 patients in clinical trials of the treatment of spinal tuberculosis, of tuberculosis meningitis and of pulmonary tuberculosis with short-course regimens containing rifampicin, isoniazid, streptomycin and pyrazinamide. The incidence was high in patients treated with daily regimens of isoniazid and rifampicin: 16-39% in children with tuberculous meningitis, 10% in patients with spinal tuberculosis (non-surgical cases), and 2-8% in those with pulmonary tuberculosis. Hepatitis, in those receiving rifampicin occurred more often in slow than in rapid acetylators of isoniazid, the proportions amongst those whose acetylator phenotype had been determined being 11% of 317 slow acetylators and 1% of 244 rapid acetylators. In children with tuberculous meningitis, the risk of hepatitis with isoniazid 20 mg/kg (39%) was higher than that with 12 mg/kg (16%), and appreciably lower in patients given rifampicin twice-weekly (5%) rather than daily (21%). There was no indication that pyrazinamide contributed to the hepatic toxicity.

Abstract
Chemotherapy studies were undertaken in 180 patients with tuberculous meningitis. They were treated for 12 months with 1 of 3 regimens: the first consisted of streptomycin, isoniazid and rifampicin daily for the first 2 months, followed by ethambutol plus isoniazid for 10 months; in the second, pyrazinamide was added for the first 2 months, and in the third, rifampicin was reduced to twice weekly in the first 2 months. Steroids were prescribed for all the patients in the initial weeks of treatment. Approximately 50% of the patients were aged less than 3 years. On admission, 13% of the patients were classified as stage I, 77% as stage II and 9% as stage III. Cerebrospinal fluid (CSF) culture results were available for all the 180 patients and M. tuberculosis was isolated in 59 (33%). CSF smear results for acid fast bacilli were available only for the 103 patients admitted to the second and the third studies, and of these in 60 (58%) the CSF was positive either by smear or culture. The response to therapy was similar in the 3 studies. Despite administration of rifampicin for 2 months, the mortality was high. In all, 27% of the patients died of tuberculous meningitis, 39% had neurological sequelae and 34% recovered completely. There was a strong association between the stage on admission and the mortality rate, the deaths being highest in stage III. In the first study, when isoniazid was prescribed daily in a dosage of 20 mg/kg, 39% of the patients developed jaundice; however, when the dosage was reduced to 12 mg/kg, the incidence fell to 16%. In the third study, where rifampicin was administered twice a week, the incidence of jaundice was much lower (5%).

Abstract
"The migration data of the census relate to surviving migrants only. Therefore those who had moved out from region i to j, but died before the census date cannot be taken into account while calculating migration rates. By correcting the Indian migration data for mortality risk, the extent of under estimation of migrants has been found to be about 4.8 percent for a duration of 5 year period and 9.7 percent for a duration of 10 years prior to the Census of 1971."

Abstract
A survey of the freshwater snails, Pila scutata and Bellamyia ingallsiana, as food consumed by the local population was carried out in Peninsular Malaysia. Of these two species the first is preferred; the sizes favoured are between 25--40 mm. Pila snails were found to be consumed by the three communities, viz. Malay, Chinese and Indian, in different ways. The various methods of preparing the snails for consumption are described. P. scutata is an intermediate host of the rat-lung worm, Angiostrongylus malaysiensis. As this worm presumably is the causative agent of human eosinophilic meningoencephalitis, the eating habits of the three races in consuming the snail in relation to the epidemiology of the disease was also discussed.
