In order to study the value of the tetrazolium nitroblue test (TNB) in the localisation of urinary tract infections, the authors performed this test in 33 patients with a urinary tract infection and in 20 control children suffering from no bacterial infection. The 33 infected children were divided into three groups on the basis of clinical and bacteriological criteria (dysuria, frequency, fever, abdominal pain, inflammatory syndrome, immunofluorescence of bacteriuria, serum antibody levels): -- group A (8 children): upper urinary infection -- group B (14 children): lower urinary infection -- group C (11 children): urinary infection of undetermined site. The number and percentage of TNB positive polynuclears was significantly higher in the children of group A than in the children of group B (p 0.001). By contrast there was no significant difference between the results obtained: in the non-infected control group and in group B -- in group A and group C. These results, confirming a previous study by Bjorksten and de Chateau, show the value of the TNB test in the localisation of urinary tract infection in the child.

The treatment of patients with sickle cell disease and cholelithiasis is controversial. This retrospective study assesses the outcome of preoperative transfusion and timely cholecystectomy in symptomatic sickle cell disease patients. Fourteen patients who had undergone cholecystectomy were determined to have sickle cell disease. The patients' mean age was 17.9 years. Eleven patients were female. Thirteen patients had complained of abdominal pain. Ultrasound confirmed the diagnosis of cholelithiasis in 12 of 13 patients tested. Hemoglobin before treatment averaged 7.7 g/dL. Transfusion or exchange transfusion was given to 12 patients, raising the average hemoglobin to 10.3 g/dL. Postoperative morbidity was 14%: one patient had a urinary tract infection and another a left-lower-lobe pneumonia. No sickle cell crises or deaths occurred. Postoperative hospital stay averaged 4.4 days. With judicious use of preoperative transfusion, early cholecystectomy for symptomatic gallstones was well tolerated by sickle cell disease patients and is advisable to avoid the morbid sequelae of acute cholecystitis and peroperative sickle cell crisis.

In order to determine metabolic disorders in children with urolithiasis, 50 patients with urinary calculi were studied. Abdominal pain and/or haematuria were the most predominant symptoms. Surgical procedures were required in 22% of these children and urinary tract infection was observed in 34% of this group. Only 2 children had anatomical malformations of the urinary tract. Absorptive hypercalciuria (32%), renal hypercalciuria (34%) and uric acid hyperexcretion (24%) were the most common metabolic abnormalities in these children. We were unable to find an underlying metabolic abnormality in only 14% of the patients. These data suggest that appropriate metabolic study will allow rational management of children with urinary stones.

In this series, nine pregnant patients had appendectomy. Seven patients had acute appendicitis; pyuria and symptoms suggesting urinary tract infection delayed diagnosis in one whose appendix perforated. Abdominal pain and nausea with or without vomiting were presenting symptoms in all of the patients. Tenderness in the right lower quadrant was present in six. Eight patients, including two with a normal appendix, had leukocytosis with a left shift. There was no fetal or maternal loss. In addition, I reviewed more than 900 other cases of appendectomy during pregnancy, as reported in the literature since 1960. Among 713 previously reported cases of confirmed appendicitis, rupture had occurred in 25%. There were five maternal deaths, all in the group of patients with perforation. Perinatal mortality was 4.8% among patients with acute inflammation only and 19.4% in those with perforative appendicitis. The diagnosis rests on clinical acumen, and prompt surgical intervention is the key to good outcome.

Blind ending bifid ureter is a rare anomaly in the urinary tract. This anomaly may result from failure of a premature branch of the ureteral bud to join with the metanephric blastema. A 21-year-old man was admitted with macroscopic hematuria and colic pain in the left flank region. Urinalysis demonstrated hematopyuria and excretory urography suggested bifid ending accessory ureter with a stone on the left side. Surgical exploration showed that the accessory ureter was bifurcated from the left ureter at about 5 mm from the bladder wall and ran parallel with the left ureter. Although dense adhesions to the surrounding tissue existed, the accessory ureter was resected at the site of the junction. It measured 3 cm in length and 1 cm in greatest diameter. The stone found at the tip of the accessory ureter was composed of calcium oxalate (24%) and calcium phosphate (76%). Histological examination revealed that the ureter had all layers of normal ureteral structure and no renal tissue was identified in the specimen resected. During a follow-up period of 22 months after the operation, he was free of urinary tract infection and abdominal pain. Of 77 cases with blind ending bifid ureter reported in the Japanese literature, a ureteral stone was found in the blind branch in only 5 cases.

Between June 1979 and June 1989, 54 children with urolithiasis were evaluated and treated at the Johns Hopkins Children's Center. The most common symptoms were flank or abdominal pain (58%) and gross hematuria (28%). In 46 children (86%), stones were secondary to a preexisting condition and in only 8 (14%) no apparent cause of stone formation could be found. Thirty-six patients (66%) had a solitary stone, most commonly found in the kidney. Urinary tract infections were present in 25 (47%) of the patients who had stones. Stones composed either of calcium oxalate or struvite were the most frequently recovered in these patients with infections. Twenty-one patients (39%) spontaneously passed their stones whereas 23 (43%) required either surgery or extracorporeal shock-wave lithotripsy to resolve stones. Ten (20%) showed recurrence of their urolithiasis, with follow-up examination periods ranging from 1 month to 10 years. Recent advances in the management of urolithiasis and their applicability to the pediatric population are discussed.

The purpose of this study was to define manifestations of autosomal dominant polycystic kidney disease (ADPKD) in older patients with the disease. Fifty-seven subjects age 50 years or more, who were at risk for having inherited the gene for ADPKD, were evaluated for renal size, hypertension, back and abdominal pain, symptoms consistent with urinary tract infection (UTI), hematuria, end-stage renal failure, and liver cysts. The diagnosis of ADPKD was made in 32 of the 57 at-risk subjects (56%). At the time of study, only one patient with the disease was asymptomatic and normotensive and denied any previous symptoms suggestive of the disease. Clinical manifestations of ADPKD in the 31 symptomatic patients were hypertension (69%), a history of back and abdominal pain (47%), symptoms consistent with UTI (41%), hematuria (31%), and end-stage renal failure (47%). Liver cysts were found in 44% of patients. No statistically significant differences in the frequency of any manifestations of ADPKD between men and women were found, although the frequency of symptoms consistent with UTI tended to be higher in women (53%) than in men (27%). Most patients developed symptoms after the age of 40 years. Notably, 31% of the older patients with ADPKD had normal serum creatinine levels. Thus, older subjects with kidney cysts who are at risk to have inherited the gene for ADPKD, should be considered to have the disease even in the presence of well-preserved kidney function. This observation may play an important role in assessing the prognosis of older subjects at risk who have bilateral renal cysts and in genetic counseling of their relatives.

The clinical manifestations of septicemic melioidosis and other bacterial septicemia were studied at Srinagarind Hospital, Khon Kaen University. Forty-three cases of septicemic melioidosis and 68 non-melioidosis septicemia cases were analysed. By univariate analysis, the following clinical features are associated with septicemic melioidosis: male patients; age below 45 years; underlying diabetes mellitus or renal failure; pulmonary infection, impending respiratory failure and multiorgan involvement, while abdominal pain and urinary tract infection were more common in non-melioidosis septicemia. By using discriminant analysis and logistic regression, 3 features (diabetes mellitus, multiorgan involvement, and no abdominal pain or pulmonary infection) could discriminate the two groups with the accuracy of more than 85 per cent.

Much difficulties are often encountered in finding the underlying cause of recurrent abdominal pain. Clinical features may vary from one patient to the other and occasionally from one episode to the next even in the same child. The recent development of fibre optic endoscopy may well prove to have a useful diagnostic technique, particularly in those children in whom other investigations are inconclusive. The result of endoscopic examinations in children with recurrent abdominal pain comprising of 62 children aged between 3-13 years were as follows: erosion in 7 children, oesophagitis in 4 children, duodenitis in 3 children, spasm of the pylorus in 2 children, and normal findings were found in 30 children. Of the 30 patients with "normal" endoscopic findings, 7 had psychosomatic problems, 4 had allergy, 4 had urinary tract infection, 2 showed giardiasis, one had epilepsy, 1 was treated as pulmonary tuberculosis, where as in 11 patients organic as well as nonorganic abnormalities could not be found. There seem to be of no significant correlation between the endoscopic and upper gastrointestinal series findings. Endoscopy seem to be of a safe and reliable tool in the diagnosis of a number of organic intestinal lesions otherwise not detected by ordinary investigations.

To evaluate factors which might contribute to treatment failure in children with chronic constipation and soiling, we evaluated the history, physical findings, defecation dynamics, and anorectal function in 97 patients. We treated them with milk of magnesia, high fibre diet, and bowel training techniques and evaluated outcome at one year when 43% had recovered. Recovery rates were similar for boys and girls. Fifty seven per cent of the patients had not recovered. This group at the outset had more frequent soiling episodes, more severe constipation, were less likely to defecate water filled rectal balloons and to relax the external sphincter during defecation. In general girls had more severe constipation, abdominal pain, and a previous urinary tract infection than boys. Girls were more compliant during treatment and had less frequent soiling episodes at one year. Stepwise logistic regression showed that severe constipation, abnormal contraction of the external sphincter and pelvic floor during attempted defecation, and inability to defecate the 100 ml balloon in less than or equal to 1 min was significantly related to treatment failure. Defecation of smaller balloons, volumes for threshold of rectal sensation, critical volume and rectal contraction, and compliance with treatment could not predict treatment failure.
