Malrotation in the neonate is an anomaly for which there are clear indications for surgery. However, the management of the older patient with this entity is not well defined. At Arkansas Children's Hospital, we reviewed our patients who were older than two years of age with malrotation. Between 1978 and 1993, 22 cases ages 2-23 years were identified. The most common presenting symptoms were vomiting 15 (68%), colicky abdominal pain 12 (55%), and diarrhea 2 (9%). Other symptoms were hematemesis 1 (5%), and constipation 1 (5%). The duration of symptoms averaged 28 months, range 2-96 months. All diagnoses were made by upper gastrointestinal (UGI) series, except for one that was recognized during an exploratory laparotomy for an intestinal duplication. A Ladd's procedure with appendectomy was performed in all cases. A significant number of patients in our series (41%) were found to have either a volvulus or internal hernia at exploration that was not clearly demonstrated by the diagnostic studies. Intestinal resection was performed in two patients for ischemic bowel. There were no perioperative deaths. Postoperative complications consisted of a wound infection in one patient. Total relief of symptoms occurred in 64% of patients. All patients with volvulus or internal hernia had resolution of symptoms, and all patients reported partial relief of their chronic symptoms. Surgical therapy eliminates the possibility of loss of bowel from volvulus or internal hernia, which is not always evident on diagnostic radiographic examination. Surgery is also highly effective in alleviating the chronic symptoms in these children. We believe, therefore, that surgical treatment is clearly indicated in the older child with proven malrotation.

In order to examine the presentation and course of Crohn's disease (CD) versus those of ulcerative colitis (UC) in children < or = 10 years of age, a retrospective review of children < or = 10 years old with inflammatory bowel disease singled out 40 patients and compared their findings with those of 38 children with UC. The mean age at onset was 7.5 years for CD, as compared with 5.9 years for UC. A family history of inflammatory bowel disease was present in 13 patients (32%). Abdominal pain (97%), diarrhea (78%), and weight loss (88%) were the major initial complaints, with growth retardation present in 12 (30%) children. At onset, four children had diffuse small-bowel disease, nine had terminal ileal disease, 15 had ileocolitis, and 12 had colitis; at the end of the study two had diffuse small-bowel disease, four had terminal ileal disease, 25 had ileocolitis, and seven had colitis. Extra-intestinal manifestations increased with duration of disease. Although the number of recurrences did not differ greatly between groups, those with ileocolitis and colitis needed longer steroid therapy and more days in hospital than did those with only small-bowel disease. Operation was required in 42.5% of children with CD, as compared with 5% of those with UC, with six CD children (35%) requiring later reoperation for recurrent disease or fistula and abscess. Two children died from causes unrelated to their disease (gastric volvulus, carcinoma of the breast).(ABSTRACT TRUNCATED AT 250 WORDS)

Intestinal malrotation presenting beyond the neonatal period is associated with a multiplicity of symptoms, which are often non-specific and, consequently, are associated with delays in diagnosis. Pseudo-Bartter's syndrome, which mimics the manifestations of Bartter's syndrome, can be caused by a severe chloride deficiency secondary to vomiting, diarrhea, perspiration, diuretic abuse and so on. We describe a 6 year old boy who had been admitted to hospital three times during the preceding year. The patient lapsed into a critical condition with profound hypochloremia and hypokalemic metabolic alkalosis induced by extremely massive vomiting. The attacks of vomiting were spasmodic and self-limited. During the episodes of vomiting he fulfilled the criteria of pseudo-Bartter's syndrome, including hyperreninemia, hyperaldosteronism and normal blood pressure, but in the intervals between attacks he was completely asymptomatic. At the third admission, examination supported an overall clinical picture of bowel obstruction, which was confirmed by radiographic examination. Laparotomy revealed a midgut volvulus with intestinal malrotation. After surgery he made a good recovery and was symptom-free. In this patient, the high degree of hypochloremia and hypovolemia activated the renin-angiotensin-aldosterone system, then aldosterone promoted intensive reabsorption of sodium and excretion of potassium into the urine. Consequently the diagnosis of pseudo-Bartter's syndrome was establish on the basis of an extreme decrease in urinary chloride and an increase in urinary potassium concentration. It is relatively rare for vomiting due to intestinal malrotation to induce pseudo-Bartter's syndrome. The importance of considering this rare diagnosis in such cases is discussed.

The syndrome of degenerative leiomyopathy causing intestinal obstruction clinically manifests in young indigenous African children as massive megacolon without aganglionosis. Eighteen children have been seen over a 16 year period from a localized geographic area. There were 10 males and 8 females having a mean age of 9.5 years at presentation and a mean duration of symptoms of 4.3 years. The youngest was 6 months old. All had progressive abdominal distension and infrequent stooling but 11 had intermittent diarrhoea and 9 had colicky abdominal pain. Gross gaseous distension of the large bowel with extension into small intestine occurred in 9 and this extended into stomach and oesophagus in 4. Biopsy of the dilated, thin walled bowel showed smooth muscle degeneration and necrosis with replacement by fibrous tissue. Neuronal cells of Auerbach's plexus tend to be displaced into the circular layer of smooth muscle with mild inflammatory changes. Some small arteries show medial fibrosis with subintimal fibroblastic proliferation. Acetylcholinesterase and immunohistochemical staining with neural and muscle markers are within normal limits. One child died while 14 have been maintained on prokinetic agents, low residue diets, laxatives and enemas. Nine children have required surgical intervention of whom 4 had volvulus and 3 adhesive bowel obstruction. Degenerative leiomyopathy is a distinctive entity with classical clinical and histological features. The aetiology is still obscure.

The objectives of this study were to investigate the determinants of the anion gap (AG) in cattle and to evaluate the utility of AG in detecting hyperlactatemia in sick neonatal calves and adult cattle. The AG was calculated as AG = ([Na+] + [K+])-([Cl-] + [HCO-3]), with all values in mEq/L. The AG of healthy neonatal calves (n = 16) was 29.6 +/- 6.2 mEq/L (mean +/- SD), and the blood L-lactate concentration ranged from 0.5 to 1.2 mM/L. The AG was significantly (P < .05) correlated with serum phosphate (r = .66) and creatinine (r = .51) concentrations. The AG of neonatal calves with experimentally induced diarrhea (n = 16) was 28.6 +/- 5.6 mEq/L, and the blood L-lactate concentration ranged from 1.1 to 2.9 mM/L. The AG was significantly correlated with blood L-lactate concentration (r = .67), serum phosphate concentration (r = .63), creatinine concentration (r = .76), and blood pH (r = -.61). The AG of adult cattle with abomasal volvulus (n = 41) was 20.5 +/- 7.8 mEq/L, and the blood L-lactate concentration ranged from 0.6 to 15.6 mM/L. The AG was significantly correlated with blood L-lactate concentration (r = .60), serum phosphate concentration (r = .71), creatinine concentration (r = .65), albumin concentration (r = .47), total protein concentration (r = .54), blood pyruvate concentration (r = .67), and blood pH (r = -.41) but not plasma beta-OH butyrate concentration. The results indicate that the AG in cattle is only moderately correlated with blood L-lactate concentration and is similarly correlated with serum phosphate and creatinine concentrations in neonatal calves and adult cattle, as well as with serum albumin and total protein concentrations in adult cattle. Anion gap determination is of limited usefulness in predicting blood L-lactate concentration in sick cattle, whereas the correlation between AG and serum creatinine concentration in sick cattle suggests that an increased AG should alert the clinician to the potential presence of uremic anions.

Colonic volvulus is a rare complication of celiac disease. A case is reported of a 46-year-old man with a long-standing history of diarrhea and abdominal distention with a diagnosis of irritable bowel syndrome. After an elective inguinal hernia repair, a cecal volvulus and an ulcerative jejunoileitis developed in the patient that required an extensive intestinal resection. Short bowel syndrome developed and was treated with total parenteral and enteral nutrition. The patient had a poor course after reinitiation of oral diet. Subsequently, celiac sprue was diagnosed and the patient improved with a gluten-free diet.

Pneumatosis intestinalis is defined as the presence of gas within the bowel wall. Small bowel pneumatosis is less commonly reported and more severe than colonic disease in adults. Pneumatosis coli is characterised by multiple collections of encysted gas occurring within the sub-mucosa and subserosa of the colon and rectum. It is an uncommon condition which typically presents in late middle age and has been associated with a number of gastrointestinal (e.g. pyloric stenosis, sigmoid volvulus and ischaemic bowel) and non-gastrointestinal (e.g. chronic obstructive pulmonary disease, depression and multiple sclerosis) diseases. Some cases, however, are idiopathic or primary. Symptoms can include diarrhoea, constipation, mucus per rectum, bleeding, flatus, abdominal pain and, rarely, faecal incontinence. We report on two patients, one of whom presented with faecal incontinence, the other who had troublesome lower gastrointestinal symptoms including faecal incontinence. Both responded well to continuous oxygen therapy.

Vomiting or its lesser stages-anorexia, nausea-is a prime symptom of the most serious surgically curable diseases of childhood. In the newborn, when vomitus is green, abdomen scaphoid, and erect roentgen view shows air-fluid levels in stomach and duodenum with gas beyond, partial duodenal obstruction is present and midgut volvulus with malrotation is likely enough to justify immediate exploration. In infancy, vomiting is a clear sign of intussusception when associated with intermittent colicky pain, palpable mass and "currant-jelly" feces. These symptoms are not always present, and if there is blood in the feces, barium enema study must follow. In further doubt, exploration may be justified. In childhood, a common early symptom of appendicitis is vomiting accompanied by pain without any complete remission. Constipation is frequent but diarrhea may occur and contribute to an impression of gastroenteritis. Complete and repeated physical examination, with a history of the above symptoms, should lead to correct diagnosis.

Volvulus of the intestine has recently been observed in three patients with idiopathic steatorrhea in relapse. Two patients gave a history of intermittent abdominal pain, distension and obstipation. Radiographic studies during these attacks revealed obstruction at the level of the sigmoid colon. Reduction under proctoscopic control was achieved in one instance, spontaneous resolution occurring in the other. The third patient presented as a surgical emergency and underwent operative reduction of a small intestinal volvulus. Persistence of diarrhea and weight loss postoperatively led to further investigation and a diagnosis of idiopathic steatorrhea. In all cases, treatment resulted in clinical remission with a coincident disappearance of obstructive intestinal symptoms. The pathogenesis of volvulus in sprue is poorly understood. Atonicity and dilatation of the bowel and stretching of the mesentery likely represent important factors. The symptoms of recurrent abdominal pain and distension in idiopathic steatorrhea necessitate an increased awareness of intestinal volvulus as a complication of this disease.

The subject of malrotation and midgut volvulus in infancy and childhood is reviewed from the perspective of experience with 138 patients evaluated in a published series and a further 82 cases seen since. Embryology, historical aspects, clinical presentation, investigation, surgery, and outcome are discussed. The diagnosis of malrotation and volvulus should always be kept in mind when assessing any infant or child with symptoms of vomiting and pain, particularly when the vomiting is bile-stained. The diagnosis cannot be excluded if diarrhea is present, when clinical findings are bland, or even with normal abdominal radiographs. A contrast meal and follow-through should be done and, if correctly interpreted, should be diagnostic. Ultrasound examination may be helpful but is not secure enough to exclude the diagnosis. Laparotomy or laparoscopy is the only way to be sure. Malrotation with its propensity for volvulus is truly a time bomb lying within.
