Predictors of intestinal parasitosis in school children of Kashmir : A prospective study.

Objectives: To identify the factors associated with intestinal parasitosis in rural and urban school children of Kashmir. Methods: Single fresh stool samples from rural and urban school children in three age groups: a)5 to < 8 years ,b) 8 to <11 years and c)11-14 years were taken .Various demographic characteristics considered were source of drinking water, type of toilet used and social classes as per the Kuppuswamy social scale. Personal hygiene was assessed by the visiting physician based on length of nails, hair and frequency of bathing. Stool samples were analyzed for detection of motile forms of E. histolytica and microscopic examination under low power detected eggs of intestinal helminths. Concentration methods were used if egg count was low. Results: 274 stool samples from rural school children and 240 samples were taken from urban school children respectively. 214 (46.7%) students had stool tests positive for parasitosis. Ascariasis was the most prevalent parasitosis ( 28%) followed by Giardiasis ( 7%) , Trichuriasis( 5%) and Taeniasis( 4%). There was higher prevalence of parasitosis among rural orphanage children compared to urban orphanage students (76% vs. 48% p <0.05). Highest prevalence of 70% was seen in the age group 8-11years. Students using river/stream water had higher rates of parasitosis compared to those who were using tap water. 202 students were found to have poor personal hygiene and parasitosis was higher in them compared to students with good personal hygiene (p<0.05). Conclusion: Poor environmental sanitation, personal hygiene, type of toilet and water used were associated with recurrent intestinal infestation besides socio economic status. Regular deworming programmes need to be adopted at school level especially in 8-11 years old children to check the surge of intestinal parasites and their subsequent morbidities.

Correlation of hepatic venous pressure gradient with variceal bleeding, size of esophageal varices, etiology, ascites and degree of liver dysfunction in cirrhosis of liver.

An elevated hepatic venous pressure gradient (HVPG) has been associated with risk of variceal bleeding, and outcome and survival after variceal bleeding. In this pilot study, we measured HVPG in 40 patients with liver cirrhosis and studied its relationship with etiology of liver disease, esophageal variceal size, history of variceal bleeding or ascites, biochemical liver tests and Child-Pugh class. There was no procedurerelated complication. The mean (SD) HVPG was similar in patients who had history of variceal bleeding as compared to those who did not (15.4 [2.8] mmHg vs. 13.9 [2.7] mmHg, p=0.1); HVPG had no significant association with etiology of cirrhosis (p=0.4). HVPG levels were significantly higher in patients with larger esophageal varices (grade III/IV vs. I/II: 15.2 [2.7] mmHg vs.13.1 [2.8] mmHg, p=0.04), poorer Child- Pugh class (B or C versus A), and presence of ascites (p=0.04). Thus, HVPG correlated with variceal size, Child-Pugh class, and presence of ascites, but not with variceal bleeding status.

Effect of bending exercise on gastroesophageal reflux in symptomatic patients.

BACKGROUND: Recumbency and bending are thought to provoke symptoms of reflux in patients with gastroesophageal reflux disease (GERD). The effect of exercise which involved bending and abdominal contractions was evaluated in symptomatic patients of GERD using continuous 24-hour ambulatory esophageal pH test. METHODS: Twenty-five patients with GERD, confirmed by abnormal 24-hour esophageal pH study, performed exercise for 30 minutes consisting of 5 sessions of 6 minutes each. The exercise involved toe touching from supine, sitting and standing position of 2 minutes' duration each. Each 2 minutes' period included 8 repetitions of the same exercise of 15 seconds' duration. 24-hour esophageal pHmetry was done on day 1 without exercise and on day 2 with 30-minute exercise. Reflux time percent (RT%) pH <4 was compared between days 1 and 2 and 30 minutes before and during exercise. RESULTS: Fourteen patients were upright refluxers and 11 patients were combined refluxers, which included 4 patients with supine reflux and 7 patients who refluxed both in supine and upright positions. The median (range) 24-hour RT% on day 1 and day 2 was 7 (5-40) and 7 (4-46), respectively (p=0.15). RT% during 30 minutes exercise compared with 30 minutes before exercise was 6.6 (0-60) and 0.0 (0.0-80) (p=0.02), respectively. In combined and upright refluxers, RT% during and before exercise was 13 (0-53) and 0.0 (0.0-42) (p=0.008), respectively and 0.0 (0-60) and 0.0 (0-80), (p=0.71), respectively. RT% between upright and combined refluxers during exercise was 0.0 (0-60) and 13 (0-53), respectively (p=0.004). The mean (SD) LES pressure in mmHg in combined and upright refluxers was 7 (2.9) and 19.6 (6.8), respectively (p=0.008). Esophagitis in combined and upright refluxers was seen in 8 patients (72.7%) and 2 patients (14.3%), respectively. Two patients (8%) developed symptoms during exercise. CONCLUSION: Exercise which involves bending precipitates reflux in patients with moderate-to-severe GERD.
