Fifteen burned children were noted to have developed renal calculi at our institution over the past 20 years. Primary risk factors appear to be immobilization and a high intake of dairy products and antacids. Presenting symptoms and physical signs include abdominal pain, haematuria, with transient leukocytosis and elevations of the blood urea nitrogen. Conservative therapy with increased fluid administration and urine acidification were successful in 13 of the patients. The remaining two patients required surgical extraction. There were no long-term renal sequelae in any of the patients.

Twenty patients underwent placement of a jejunal catheter for early postoperative feeding at the time of upper abdominal operations, and a control group of 11 patients underwent operative procedures of similar magnitude without jejunostomy. Advancement of the rate of feeding to target intake over 6 to 7 days was attempted. Complications from the feeding led to cessation or curtailment of intake in 65 percent of the patients. Specific complications included abdominal pain and distention, diarrhea, and retrograde reflux of the feeding into the stomach. No statistically significant difference in nitrogen balance was demonstrated between the fed and unfed groups, presumably due to the limitations of nutrient delivery or absorption in the fed groups or elevated breath hydrogen excretion in patients with abdominal pain and distention suggests that the nature of the nutrients, particularly complex carbohydrates, is a factor in the development of feeding complications. Caution must be exercised in advancing the rate of postoperative jejunal feeding.

DT, a 63-year-old white male with insulin-dependent diabetes mellitus and severe peripheral vascular disease, was admitted with a five-day history of vague abdominal pain and diarrhea. On the day of admission he vomited three times, was noted to have a bloody stool, and came to the emergency room. DT denied hematemesis, fever, or chills. He had bilateral leg amputations and had sustained three myocardial infarctions, the last one 15 months before this admission. He had never experienced symptoms of abdominal angina. Of significance was his history of congestive heart failure, mitral regurgitation, and atrial fibrillation. His medications on admission included digoxin 0.25mg per day, furosemide 40mg per day, and NPH insulin 15 units per day. On admission to the hospital his oral temperature was 38 degrees C, pulse was 90/min, respiratory rate was 24/min, and blood pressure was 134/80mmHg. Abdominal examination revealed a distended abdomen with hypoactive bowel sounds and mild tenderness. Chest x ray revealed cardiomegaly. The electrocardiogram demonstrated atrial fibrillation. A plain film of the abdomen was positive for gallstones and edema of the bowel wall (thumb-printing). Laboratory results included blood urea nitrogen 48mg%, creatinine 1.2mg%, hemoglobin 18g/dl, and hematocrit 52.9%. White blood cell count was 11,900 cells/cc with 33% polymorphonuclear leukocytes, 47% bands, 8% lymphocytes, 11% monocytes, and 1% atypical lymphocytes. The prime considerations for differential diagnosis were mesenteric ischemia and infectious gastroenteritis. While it was appreciated that mesenteric ischemia, if present, might warrant surgical intervention, the risk of anesthesia itself in this patient was felt by his attending physicians to exceed 30%. Furthermore, the clinical findings were only "suggestive" of mesenteric eschemia. They were certainly not "diagnostic." In view of this dilemma, a consultation with the Division of Clinical Decision Making was requested.

A 34-year-old male with hypereosinophilic syndrome (HES) and cardiac complications was treated with recombinant human alpha-interferon (rhIFN) and recombinant human granulocyte colony-stimulating factor (rhG-CSF) in the attempt to suppress the eosinophilic cell clones and stimulate the neutrophil myelopoiesis in the bone marrow, respectively. After 1 month of pretreatment with rhIFN, rhG-CSF was administered daily for 22 days. Within a few days the combined treatment with rhIFN and rhG-CSF was followed by a marked increase in absolute neutrophil count but complicated by abdominal pain and an increase in plasma creatinine and blood urea nitrogen. The renal failure persisted when rhIFN therapy was stopped but resolved after discontinuing rhG-CSF. The pathogenesis of this reversible renal involvement needs further investigation. In that hematological improvement in vivo as well as in vitro followed the administration of rhIFN and rhG-CSF, a role for combined therapy with these cytokines may be advocated. However, caution with regard to kidney function should be taken with this combination therapy.

Our aim was to evaluate the response to intraluminal gas in irritable bowel syndrome and to determine whether this response was consequent upon disordered motility or altered perception. We evaluated 10 patients who satisfied the clinical criteria for the diagnosis of irritable bowel syndrome and 10 healthy controls. An eight-lumen perfused catheter assembly was positioned to monitor motor activity in the duodenum and proximal jejunum; a separate side port in the distal duodenum permitted gas infusion. Subjects recorded symptoms of abdominal pain, bloating, and nausea throughout the study, using a visual analog scale. Following an overnight fast and a 60-min basal recording period in the fasted state, subjects ate a standard meal; 60 min later, "sham" gas was administered for 20 min, followed by the actual infusion of nitrogen gas at 40 ml/min. Subjects were randomized to receive atropine (7 micrograms/kg) or placebo intravenously during the period of actual gas infusion. Patients with irritable bowel syndrome described more pain (score, mean +/- SE, control versus irritable bowel: 0.22 +/- 0.16 vs 1.65 +/- 0.5, P < 0.01) and nausea (0.25 +/- 0.21 vs 1.45 +/- 0.64, P < 0.04) during sham gas; motility indices were similar in both groups. During active gas, irritable bowel syndrome patients reported more pain (0.40 +/- 0.39 vs 2.94 +/- 1.16, P < 0.03); motility indices at all sites were similar in both groups. Symptom severity in irritable bowel syndrome subjects randomized to receive atropine was similar to control subjects during active gas infusion; motility indices were similar.(ABSTRACT TRUNCATED AT 250 WORDS)

Haemorrhagic fever with renal syndrome (HFRS) is an acute disease caused by Hantavirus and clinically characterised by abrupt onset of fever, various haemorrhagic manifestations and transient renal and hepatic dysfunction. We retrospectively reviewed 63 cases of HFRS in children from 13 different hospitals in Korea who presented over a 15-year period. The age of the patients ranged from 7 to 15 years, with a male to female ratio of 8 to 1. Fifty-four (86%) patients were 10 years or older. On admission, 24 (38%) were in the febrile phase and 35 (56%) were in the oliguric phase. Fever (100%) abdominal pain (91%), headache (76%) and vomiting (73%) were the most common symptoms. Backache, subconjunctival haemorrhage and hypertension were also noted in about one-third of patients. Hypotension was documented in only 7 (11%) patients. Leucocytosis (> 10,000/mm3) and thrombocytopenia (< 150,000/mm3) were noted in more than two-thirds of patients. Elevated blood urea nitrogen and serum creatinine was observed in 94% by the 7th (median) day of illness. Elevated aspartate aminotransferase and/or alanine aminotransferase were found in more than two-thirds of patients. Renal biopsy was performed in 12 patients and revealed various stages of acute tubular necrosis with occasional interstitial cell infiltration and oedema. Only 2 showed evidence of interstitial haemorrhage. Eleven patients required 1-3 days of dialysis and the remaining patients required only conservative management. Three (5%) patients died of shock, respiratory failure and pulmonary haemorrhage. All other patients recovered without sequelae. Although childhood cases were much less common than adults, clinical and laboratory findings were in general similar between children and adults.

Although surgical procedures that improve pancreatic drainage alleviate abdominal pain in the vast majority of patients with chronic pancreatitis, postoperative absorption and nutritional status are less predictable. The present study was designed to determine the efficacy of pancreatic enzyme supplementation in maintaining postoperative digestion and nutrition in patients who had received the local resection-longitudinal pancreaticojejunostomy (LR-LPJ) procedure for chronic pancreatitis. We evaluated nutritional status and intestinal absorption in 11 patients who had undergone LR-LPJ. The efficacy of postoperative pancreatic enzyme supplementation was studied by measurements of intestinal absorption and nutritional status at baseline, after 4 weeks of individualized daily dosage of pancreatin (Creon), and after an additional 4 weeks of randomization to receive another 4 weeks of pancreatin or placebo. All patients demonstrated abnormal digestion of fat, protein, and total energy at baseline 3 weeks after surgery. Pancreatin supplementation significantly improved the coefficients of absorption of dietary fat and total energy over the next 4 weeks. Between 4 and 8 weeks, pancreatin significantly improved protein absorption and nitrogen balance, whereas placebo substitution worsened the absorption of dietary fat and total energy. Nutritional status was not significantly altered over the 8-week study period, although four patients receiving pancreatin gained more than 3.6 kg body weight. The data suggest that long-term postoperative pancreatic enzyme supplementation is both efficacious and necessary in chronic pancreatitis patients after LR-LPJ.

We describe a case of peripheral T cell lymphoma that is remarkable for its fulminate course and selective targeting of both kidneys. The patient was a 6-year-old girl who was in her usual state of good health until the onset of abdominal pain and fever. She was treated for acute oliguric renal failure and visual disturbances. A renal biopsy was performed. Biopsy findings were interpreted as suggestive of a vasculitic process, and treatment was initiated for a presumptive diagnosis of Wegener's granulomatosis. The patient died 3 days following admission, and autopsy revealed extensive bilateral kidney infiltration by a peripheral T cell lymphoma. The remainder of the body was spared with the exception of mild infiltration of the pulmonary parenchyma and choroid plexus by neoplastic lymphocytes. The neoplastic nature of the disease was confirmed utilizing immunoperoxidase stains and T cell receptor gene rearrangement. Primary renal lymphoma and renal failure attributable to involvement by lymphoma are rare findings that should be considered when other more common causes of renal insufficiency have been excluded. The presenting clinical complaints are generally of short duration, nonspecific, and atypical. Most patients exhibit oliguria. Physical examination may reveal hepatosplenomegaly, lymphadenopathy, and flank and/or abdominal mass(es). Laboratory findings frequently include an elevated serum creatinine, blood urea nitrogen, lactate dehydrogenase, and a mild proteinuria. Electrolyte abnormalities are variably present. Possible radiographic findings include hypodense or hypoechoic renal lesions and diffuse bilateral renal enlargement. Although the prognosis is dismal, survival may be prolonged utilizing current treatment modalities, and rare patients may be "cured" of disease. The clinical presentation, radiological findings, and prognosis of patients with clinically evident renal involvement by non-Hodgkin's lymphoma are discussed.

The role of early CT scanning in acute gallstone pancreatitis remains ill defined. The purpose of our study was to: 1) determine whether our previously identified admission prognostic factors for gallstone pancreatitis [white blood cell (WBC) count > or = 14.5 x 10(9)/L, blood urea nitrogen (BUN) > or = 12 mmol/L, Acute and Chronic Health Evaluation II score > or = 5, glucose > or = 150 mg/dL, and heart rate > or = 100 beats/min)] correlate with the severity of pancreatic inflammation on CT scan, and 2) to determine the utility of early CT scanning in the management of gallstone pancreatitis. Admission clinical and laboratory variables were collected prospectively. Early CT scan findings were graded using the Balthazar scoring system and subgrouped into mild-moderate (Balthazar grades A-C) or severe (grades D and E) by a radiologist blinded to the patients' clinical status. Ninety-seven patients underwent surgery during their initial hospitalization without preoperative CT scanning. Four had operative complications (4%). Forty-two patients underwent early CT scan (grade A, 19%; B, 5%; C, 21%; D, 10%; and E, 45%), but only four (all grade E) had surgery delayed because of necrotizing pancreatitis, abscess, or pseudocyst. All four had persistent abdominal pain. There was one (2.5%) operative complication in the CT group and no deaths. Admission WBC count > or = 14.5 x 10(9)/L and BUN > or = 12 mmol/L correlated with severe pancreatitis (grades D and E) on CT (P < .05). We conclude that in patients with gallstone pancreatitis, 1) admission WBC count > or = 14.5 x 10(9)/L and BUN > or = 12 mmol/L correlate with the severity of pancreatic inflammation on CT scan, and 2) CT scan findings rarely influence management decisions and CT is therefore unnecessary, except in the minority of patients with objective indications of severe or unresolving pancreatitis.

Diabetic ketoacidosis (DKA) is frequently associated with pancreatic enzyme abnormalities. In order to determine the main factors that lead to this increase, serum total amylase (TA), pancreatic amylase (PA), lipase (L) and leukocyte elastase (LE), an early predictor of acute pancreatitis, were measured in four groups of patients on admission. Group 1 consisted of 52 patients with DKA (age: 41.9 +/- 19.2 years; blood glucose (Glc): 27.4 +/- 11.5 mmol/L; pH: 7.20 +/- 0.16; plasma bicarbonate: 10.5 +/- 6.2 mmol/L; blood urea nitrogen (BUN): 0.60 +/- 0.44 g/L; HbA(1C): 12.5% +/- 2.8%). Group 2 consisted of 90 patients with poorly controlled non-ketotic diabetes (age: 53.4 +/- 16.0; Glc: 14.3 +/- 0.6; HCO(3)(-): 26.6 +/- 3.2; BUN: 0.38 +/- 0.20; HbA(1C): 11.3 +/- 2.1). Group 3 consisted of 22 patients with well-controlled diabetes (age: 53.7 +/- 12.8; Glc: 10. 1 +/- 5.2; HCO(3)(-): 27.4 +/- 3.8; BUN: 0.36 +/- 0.19; HbA(1C): 6.8 +/- 0.8). Group 4 (controls) comprised 27 non-diabetic patients (age: 46.0 +/- 15.0; Glc: 4.9 +/- 0.5; HCO(3)(-): 28.4 +/- 2.5; BUN: 0.30 +/- 0.16; HbA(1C): 5.2 +/- 0.7) (means +/- SD). Increased enzyme activities were more frequent in group 1 (TA: 30.7; PA: 27.0; L: 36.5; LE: 73%) than in groups 2 (TA: 8.9; PA: 7.1; L: 8.9; LE: 45. 5%), 3 (TA: 13.6; PA: 9.0; L: 18.1; LE: 31.8%) and 4 (TA: 7.0; PA: 3. 0; L: 0.0; LE: 29.6%). Mean serum enzyme activities were significantly different in the 4 groups (ANOVA, P < 0.01) and were higher in group 1 than in groups 2, 3 and 4 (Student's t-test; group 1 vs 2 or 3 or 4: P < 0.001). In groups 1 + 2 + 3 + 4 (all patients), the four enzymes correlated with one another and also with Glc, BUN and HCO(3)(-) (P < 0.001). In group 1, TA correlated negatively with HCO(3)(-) (P < 0.001) and pH (P < 0.05); PA and L correlated positively with Glc and BUN (P < 0.01) and negatively with HCO(3)(-) (respectively, p < 0.01 and 0.05). PA correlated positively with pH (P < 0.01); LE correlated with Glc (P < 0.05) and BUN (P < 0.01). In conclusion, this study suggests that the serum levels of pancreatic enzymes increase with the degree of diabetic disequilibrium, and mainly correlate with metabolic factors such as hyperglycaemia, dehydration and acidosis. Increased pancreatic enzyme activities in patients with DKA, even in combination with abdominal pain, should not be diagnosed as acute pancreatitis; this could be important, particularly for younger clinicians.
