Objective: To evaluate the role of gastrointestinal (GI) endoscopy in human immunodeficiency virus (HIV)‐infected children with GI problems. Methods: From 1998 to 2002, we retrospectively reviewed all cases of HIV‐infected children presenting with GI problems in which an upper or lower GI endoscopy was indicated. The initial diagnostic endoscopic examination and any repeat endoscopic session leading to a new diagnosis were used in the data analysis. Tissue biopsies were obtained from all abnormal lesions and representative sites of normal‐appearancing GI mucosa. Results: Fourteen patients (median age: 22.5 months) underwent 23 sessions of GI endoscopy, including 10 esophagogastroduodenoscopy, nine colonoscopy and four flexible sigmoidoscopy. Chronic diarrhea was the most common indication, followed by lower GI bleeding, abdominal/retrosternal pain, dysphagia/odynophagia, and upper GI bleeding. Gross endoscopic abnormalities were observed in 78.3%; whereas histological inflammation and opportunistic pathogens were identified in 87% and 43.5%, respectively. Cytomegalovirus was the most common identified pathogen. Abnormal gross findings were significantly associated with histological inflammation and identification of pathogens (P = 0.006 and 0.046, respectively). Specific changes in medical management were made in 50% of cases as a result of endoscopic investigation. Conclusion: If non‐invasive investigations for HIV‐infected children with GI symptoms fail to establish a diagnosis, gastrointestinal endoscopy should be performed and often yields a positive result leading to changes in medical management. 相似文献

Background The aim of this prospective study was to describe the clinical characteristics of colorectal polyp in Thai children.
Methods From December 2002 to February 2005, children under 15 years of age presenting with rectal bleeding were prospectively enrolled.
Demographic, clinical, and laboratory information was recorded. Location, number, characteristics, and histopathology of the
polyps were noted.
Results There were 32 patients with a mean age of 6.5 years. The most common presenting symptom was hematochezia, followed by prolapsing
rectal mass and diarrhea. In 20 patients there was a single polyp, 6 had 2–4 polyps, and 6 were diagnosed with polyposis coli.
Most of the polyps were located exclusively at the rectum and sigmoid colon. In only 7 cases were the polyps proximal to the
rectosigmoid region. This included 6 patients who had polyps beyond the splenic flexure. All were juvenile polyps without
evidence of adenomatous changes. Compared to those with isolated polyps, the patients with polyposis coli had a statistically
significant incidence of right-sided polyps (P <0.001) and a history of prolapse of the rectal mass (P = 0.006).
Conclusions Because of the high prevalence of right-sided polyps and the concern about malignant transformation, colonoscopy should be
considered as the initial evaluation in children with rectal bleeding. 相似文献

This analysis was undertaken to see whether or not previous successful breastfeeding has any influence on subsequent breastfeeding behavior. Lactational outcomes were compared between those with and without breastfeeding experience. METHODS: Amount of breast milk transferred, frequency of breastfeeding, and time spent on the breast, as well as infant's weight, were recorded on days 15, 45, 90, 180, 270, and 360 postpartum in 30 primiparae and 30 multiparae. Outcomes of the primiparae were found to be similar to those of the more experienced breastfeeding multiparous mothers with respect to infant growth, amount of breast milk transferred, and the frequency of breastfeeding or number of attachments to the breast. Though primiparae took somewhat longer to transfer similar amounts of breast milk to their infants during the initial 45 to 90 days postpartum, feed duration after 90 days was similar to that of the multiparae. Lactation performance of the rural northern Thai mothers in our sample was highly successful with or without previous breastfeeding experience. It may be that a cultural pattern of breastfeeding on demand, strong family support, and traditional practices that encourage close contact between mother and her newborn compensate for the absence of lactational experience. Unlike reports from Western countries, previous breastfeeding does not appear to be an important predictor of successful and prolonged breastfeeding in our population. 相似文献

This study was undertaken to see whether tubal ligation performed within days postpartum, and associated with a delay in the initiation of breastfeeding, exerts a disruptive influence on successfully establishing lactation among the rural population of northern Thailand. Lactational performance of 12 rural northern Thai mothers was not affected by the delay in reunion of mothers with their babies as a result of postpartum tubal sterilization procedure when compared with a group of 8 other healthy mothers and babies. The volume of breast milk transferred, frequency of breastfeeding and the total feeding time spent on the breast were similar on days 15, 45, 90, 180 and 360 postpartum. This finding suggests that the pattern of intense breastfeeding activity as practiced by this group of mothers has a stronger influence on prolonged and successful lactation than early contact in the immediate postpartum period. 相似文献

Cytomegalovirus-associated manifestations involving the digestive tract in children with human immunodeficiency virus infection 总被引:2,自引:0,他引:2

OBJECTIVE: To study the clinical manifestations of gastrointestinal cytomegalovirus disease in children with human immunodeficiency virus infection. METHODS: Review of clinical records of eight human immunodeficiency virus-infected children and histopathologically confirmed gastrointestinal cytomegalovirus disease from 1995 to 2001. RESULTS: Six of the eight children were younger than 1 year. The most common clinical presentations were fever and chronic diarrhea. Lower gastrointestinal hemorrhage and bowel perforation were noted in four and three patients, respectively. The colon was the most commonly affected site, followed by the small bowel and esophagus. The diagnosis was established by histopathology, obtained during endoscopy and surgery. Mucosal edema, erythema, and ulcer comprised the most common endoscopic findings. Two patients with fever, chronic diarrhea, and lower gastrointestinal bleeding developed remission after being treated with a 14-day course of ganciclovir. CONCLUSION: Gastrointestinal cytomegalovirus disease can result in serious life-threatening complications, such as bowel perforation and massive gastrointestinal bleeding. Patients with chronic diarrhea and fever of unidentified cause might benefit from gastrointestinal endoscopy for early diagnosis and treatment. Although ganciclovir does not eradicate the infection and relapses are frequent, this treatment can prevent complications and reduce morbidity. 相似文献

Samples of weaning food and supplementary water were collected for analysis of bacterial content from among a random sample of 65 infants under the age of 1 year living in a rural area of northern Thailand. Using geometric means, mean total bacterial count of infant's drinking water was 351 organisms/ml (95 per cent CIs 170-770), and the most probable number (MPN) of faecal coliforms/ml was 47 (95 per cent CIs 19-78). Mean total bacterial count of weaning foods was 38,000 (95 per cent CIs 25,000-59,000) organisms/g with 10 per cent recording counts greater than 1,000,000 organisms/g. Bacterial counts were similar to those reported in weaning food and water in other developing countries, and were above internationally recommended 'safe' levels. The bacterial count of water was not affected by boiling, due to poor cleaning and frequent re-use of utensils. Weaning foods were contaminated during preparation, in part through premastication and also via mode of cleaning of utensils. 相似文献

We report a 10‐year‐old boy presenting with generalized pitting edema, ascites, abdominal pain, and chronic mucous diarrhea for 4 weeks. He had underlying diseases of hemoglobin E and juvenile rheumatoid arthritis and had been treated with immunosuppressive agents for a long period of time, including prednisolone and methotrexate. After extensive investigations, Strongyloides stercoralis infection, leading to protein‐losing enteropathy and eosinophilic granulomatous enterocolitis, was diagnosed. In the present report, we demonstrate early colonoscopic findings, revealing patchy erythema and small raised mucosal nodules with erosions at the cecum. Histopathological study showed open ulceration with cryptitis, intense infiltration of eosinophils and histiocytes with granuloma formation, in which Strongyloides stercoralis larvae were noted. 相似文献

The aim of this study was to reassess the accuracy of the triangular cord sign, the triangular cord sign coupled with abnormal gall‐bladder length, and an irregular gall‐bladder wall in the diagnosis of biliary atresia. The ultrasonograms of 46 infants with cholestatic jaundice were reviewed for the triangular cord sign, gall‐bladder length and gall‐bladder wall without knowledge of the clinical data. Of the 23 infants with biliary atresia, 22 had the triangular cord sign whereas 17 infants with other causes of cholestatic jaundice did not have the triangular cord sign. The sensitivity, specificity, accuracy and positive predictive value of the triangular cord sign in the diagnosis of biliary atresia were 95.7, 73.9, 84.8 and 78.6%, respectively. The sensitivity, specificity, accuracy and positive predictive value of the triangular cord sign coupled with abnormal gall‐bladder length in the diagnosis of biliary atresia were all 95.7%. Gall‐bladder wall irregularity was seen in seven of 14 infants (50%) with biliary atresia whose gall bladders contained bile on ultrasound and in two of 22 infants (9.1%) without biliary atresia whose gall bladders contained bile on ultrasound. At the medical centre where this study was performed and where infants present with cholestatic jaundice at an advanced stage, the ultrasonographic triangular cord sign coupled with abnormal gall‐bladder length is more reliable than the ultrasonographic triangular cord sign alone or gall‐bladder wall irregularity in the diagnosis of biliary atresia. 相似文献
