Thirty-eight children (21 male, 17 female, age 3-18 years), treated for Crohn disease in two Dutch university centres, were retrospectively studied in order to evaluate the results of conservative treatment and to find out in what way surgical treatment in this age group may have differed from treating adults with this disease. Both groups had an equal distribution of age and sex. Diarrhoea with discharge of blood and mucus, abdominal pain, nausea/vomiting, weight loss, fever and general discomfort were the most frequent presenting symptoms. Twenty-three children (60%) showed signs of malabsorption; 4 children (10%) had growth retardation. In 27 children (70%), 63 surgical procedures were performed (2.4 operations per child). There was no surgical mortality. Most operations were performed for ileocolitis and colon-only localizations needed most re-operations. Of the surgical procedures performed, 55% were excisional procedures. Already 3 years after the onset of symptoms, 50% of all children had had their first resection, whereas in adults, 50% of the patients undergo surgery 8 years after disease onset. Eight children were treated with split ileostomy. In only one of these children, operated for non-toxic colitis and severe steroid-dependent growth retardation, could the colon eventually be saved. The time between the onset of symptoms and the first operation seems to be shorter in children compared to adults. Severe malabsorption and growth retardation are additional specific indications for surgery for Crohn disease in childhood. The latter combined with non-toxic colitis, may perhaps be the only indication left for performing split ileostomy in Crohn disease.

Duodenal diverticulosis is not a rare condition. Usually of little clinical significance, it can produce a variety of disorders such as malabsorption, hemorrhage, diverticulitis, and obstruction. The rarest complication appears to be enterolith formation and obstruction. The case presented is a 70-year-old woman with the chief complaints of intermittent abdominal pain and vomiting. At laparotomy, duodenal diverticulitis and one enterolith obstructing the distal ileum were found. The literature review presents the other 26 cases with small bowel obstruction due to an enterolith formed within a small bowel diverticulum. The diagnosis can be established only by documenting the normalcy of the gallbladder and the presence of duodenal or jejunal diverticula.

Based on experimental evidence in animals showing that the oral administration of Saccharomyces boulardii is effective in reducing morbidity and mortality due to Clostridium difficile-induced pseudomembranous colitis, we conducted an open trial to examine the effects of the living yeast, given as primary therapy, in a selected group of infants and children with persistent intestinal symptoms related to toxinogenic C. difficile overgrowth. Over a period of 10 consecutive months, we studied 19 eligible patients (median age 8 months) who presented with enteral symptoms lasting for > 15 days and who had solely C. difficile in stools with positive cytotoxin B assay. Serotyping of the strains and determination in vitro of production of toxins A and B were performed subsequently. The patients presented with persistent or protracted diarrhea, malabsorption, and failure to grow (n = 8), or with repeated attacks of colics, emesis, and hypermeteorism without diarrhea (n = 4), or with both entities (n = 7). Patients with chronic protracted diarrhea (n = 3) had depressed jejunal disaccharidase activities and ultrastructural changes of enterocytes, including sparce and shortened microvilli. None had evidence of colitis. All the strains of C. difficile tested (n = 17) belonged to pathogenic serotypes (A1, A8, C, F, G, H, and K) and produced in vitro high levels of toxins A (n = 16) and B (n = 17). S. boulardii was given orally in a lyophilized form over 15 days (250 mg two to four times per day according to age).(ABSTRACT TRUNCATED AT 250 WORDS)

After the development of monophasic combined oral contraceptives (COCs), containing a fixed dose of estrogen and progestogen, biphasic and triphasic COCs were introduced in the 1980s; in these the dose of ethinyl estradiol and progestogen changes during the pill cycle. In the so-called every day pills, the 21 pills of active steroid combination are followed by 7 inactive pills containing starch, iron, or bran. Method failures of OCs are among the lowest ranging from 0.2-1/100 woman-years. User failures can be as high as 6.2/100 women-years. The individual difference in peak plasma levels of estrogens in women taking identical OCs can be 10-fold. Conditions that affect the bioavailability of contraceptive steroids are: 1) drug interaction (vitamin C, drugs that induce liver enzymes, and antibiotics); 2) vomiting; 3) vegetarianism; 4) missing pills; and 5) malabsorption. Metabolic effects of COCs pertain to carbohydrate metabolism, lipid metabolism, hemostasis, and vitamins. Prescribing of COCs involves counseling clients about contraindications to COCs, starting routines, and the pill-free interval, as well as follow-up and monitoring, the problem of missing pills, and selection criteria for OC use. Medical conditions in which COC use requires special consideration are sickle cell disease, trophoblastic disease, HIV disease, gallstones, epilepsy, valvular heart disease, oligomenorrhea/amenorrhea, inflammatory bowel disease, and surgery. Side effects of COCs may include depression, nausea, vomiting, headaches, urinary tract infection, and lower genital tract infections. 6 months after stopping the OC 1% of users become amenorrheic. Many of the common causes of amenorrhea, such as weight loss amenorrhea and polycystic ovarian disease, may be treated with the COC until the couple desires to have a baby. The new progestogens desogestrel, norgestimate, and gestodene are highly selective compared to first and second generation progestogens.

We describe the clinicopathologic characteristics of three patients with chronic intestinal pseudo-obstruction and malabsorption. The patients were young women (average age, 25 years) who presented with abdominal pain, nausea, vomiting, diarrhea, and weight loss that led to extreme inanition and death in two patients despite multiple treatment schemes. The evolution of the process averaged 8 years. No case manifested evidence of malignant lymphoproliferative progression. Histologically, a diffuse lymphoplasmacytic infiltrate that affected all the layers of the intestinal wall was observed in full-thickness biopsy specimens. The proliferating lymphocytes were small and mixed with mature plasma cells that proved to be polyclonal on immunohistochemical analysis. An outstanding finding in all three cases was extensive damage to submucosal and myenteric nerve plexus associated with a lymphoid infiltrate. Quantification of the myenteric plexus by using immunohistochemical and morphometric techniques also revealed a marked reduction in their number. We concluded that diffuse lymphoplasmacytic infiltration of the small intestine associated with damage to the intestinal nerve plexus constitutes a specific disorder that is different from other diseases that produce intestinal pseudo-obstruction.

Digestion is a process which takes place in resting conditions. Exercise is characterised by a shift in blood flow away from the gastrointestinal (GI) tract towards the active muscle and the lungs. Changes in nervous activity, in circulating hormones, peptides and metabolic end products lead to changes in GI motility, blood flow, absorption and secretion. In exhausting endurance events, 30 to 50% of participants may suffer from 1 or more GI symptoms, which have often been interpreted as being a result of maldigestion, malabsorption, changes in small intestinal transit, and improper food and fluid intake. Results of field and laboratory studies show that pre-exercise ingestion of foods rich in dietary fibre, fat and protein, as well as strongly hypertonic drinks, may cause upper GI symptoms such as stomach ache, vomiting and reflux or heartburn. There is no evidence that the ingestion of nonhypertonic drinks during exercise induces GI distress and diarrhoea. In contrast, dehydration because of insufficient fluid replacement has been shown to increase the frequency of GI symptoms. Lower GI symptoms, such as intestinal cramps, diarrhoea--sometimes bloody--and urge to defecate seem to be more related to changes in gut motility and tone, as well as a secretion. These symptoms are to a large extent induced by the degree of decrease in GI blood flow and the secretion of secretory substances such as vasoactive intestinal peptide, secretin and peptide-histidine-methionine. Intensive exercise causes considerable reflux, delays small intestinal transit, reduces absorption and tends to increase colonic transit. The latter may reduce whole gut transit time. The gut is not an athletic organ in the sense that it adapts to increased exercise-induced physiological stress. However, adequate training leads to a less dramatic decrease of GI blood flow at submaximal exercise intensities and is important in the prevention of GI symptoms.

At least 21 genetic disorders have now been found that are linked to peroxisomal dysfunction. Whatever the genetic defect might be, peroxisomal disorders should be considered in various clinical conditions, dependent on the age of onset. The prototype of peroxisomal disorders is represented by 'classical' Zellweger syndrome (ZS) which is the most severe disorder combining all the characteristic symptoms. ZS is characterized by the association of errors of morphogenesis, severe neurological dysfunction, neurosensory defects, regressive changes, hepatodigestive involvement with failure to thrive, usually early death, and absence of recognizable liver peroxisomes. Other peroxisomal disorders (pseudo-Zellweger syndrome, neonatal adrenoleukodystrophy (NALD), pseudo-neonatal adrenoleukodystrophy, rhizomelic chondrodysplasia punctata (RCDP), and hyperpipecolic acidaemia) share some of these symptoms, but with varying organ involvement, severity of dysfunction, and duration of survival. The diagnosis should not cause difficulty when all the characteristic manifestations are present. Depending on the main presenting sign, peroxisomal disorders in neonates should be suspected in two categories of circumstances: polymalformative syndrome with craniofacial dysmorphism, and severe neurological dysfunction. During the first 6 months of life, the predominant symptoms may be hepatomegaly, prolonged jaundice, liver failure, anorexia, vomiting and diarrhoea leading to failure to thrive resembling a malabsorption syndrome; severe psychomotor retardation, hearing loss and ocular abnormalities become evident. Beyond 4 years of age, behavioural changes, intellectual deterioration, visual impairment and gait abnormalities may be the presenting symptoms. Independently of the clinical symptoms and age of onset, most peroxisomal disorders described so far can be clinically screened by recordings of electroretinogram, visual-evoked responses, and brain auditory-evoked responses, which are almost always abnormal. Nine of the 17 peroxisomal disorders with neurological involvement are associated with an accumulation of very long-chain fatty acids (VLCFA), which suggests that assay of plasma VLCFA should be used as a primary test. However, assays of plasma phytanic acid and plasma/urine bile acid intermediates should also be performed in view of the recent reports of atypical chondrodysplasia variants (without rhizomelic shortening) and isolated trihydroxycholestanoic aciduria. The differential diagnoses in various clinical conditions and age periods are discussed.

Bezoar formation is a rare but well-recognised complication of previous gastric surgery and persimmon ingestion. We present a case of bezoar formation in the duodenum of a child with a grossly dilated, dysmotile duodenum following surgery for jejunal atresia. The presenting symptoms were vomiting, diarrhoea, and growth failure, with evidence of malabsorption secondary to bacterial overgrowth in the bezoar. Plication of the duodenum to reduce its size and improve its motility may reduce the likelihood of future bezoar formation.
