Acute febrile neutrophilic dermatosis. Sweet's syndrome.

Acute febrile neutrophilic dermatosis (AFND) (Sweet's syndrome) is characterized by warm, erythematous plaques, accompanied by arthralgias, fever, and leukocytosis. A 53-year-old man was seen with chronic, recurrent, and unusually persistent AFND. The patient had a history of a gastrojejunostomy for peptic ulcer disease and had symptoms of the blind loop syndrome. Medical therapy for the blind loop syndrome failed to control his skin lesions, fever, or leukocytosis. His symptoms did respond to prednisone therapy, however. The relationship of AFND to the bowel bypass syndrome is discussed.

Intestinal blind pouch- and blind loop-syndrome in children operated previously for congenital duodenal obstruction.

A follow-up study of 27 children operated for congenital duodenal obstruction (CDO) in years 1953-71 is presented. Nine children belonged to the intrinsic and 18 children to the extrinsic group of CDO. A total of 7 retrocolic, isoperistaltic, side-to-side duodeno-jejunostomy, 7 Ladd's operation, 8 duodenolysis, 2 reduction of midgut volvulus, 2 duodenostomy a.m. Morton and one gastro-jejunostomy were performed at the age of 1 day-15 years. The clinical and radiological examinations were performed 3-21 years (mean 10 years 2 months) after these operations. In 3 cases there was a moderate duodenal dilation, but reoperation was not necessary. During the follow-up period, one boy, now aged 8 years, developed a blind pouch-syndrome in the I portion of the duodenum containing a 5 X 5 cm phytobezoar 4 1/2 years after duodeno-jejunostomy. The frequency of blind pouch-syndrome after duodeno-jejunostomy was thus 1:7 or 14%. One girl, now aged 9 years, developed a blind loop-syndrome in the ileocaecal segment 3 months after side-to-side ileotransversostomy, which was performed from adhesion-obstruction after duodenolysis for malrotation I and CDO. Both the blind pouch- and the blind loop-deformation were resected and the children recovered well. To avoid blind pouch- and blind loop-deformations in the intestines, the anastomosis must be made wide enough, and especially in the surgery of the jejuno-ileo-colic region an end-to-end anastomosis is preferable.

Tight junction regulation during impaired ion transport in blind loops of rat jejunum.

Epithelial cell tight junction structure in self-filling blind loops of rat jejunum, a model for blind loop syndrome in humans, was analyzed morphometrically along the crypt-villus axis. In control jejunum, the number of strands and junctional depth, including meshwork depth, decreased from crypt to villus tip. In the blind loop, aberrant strands appeared below the meshwork, particularly in crypt cells. Consequently, total junctional depth was greater than in controls. Furthermore, strand number and junctional meshwork depth were increased in blind loops at the villus tip. It is that site along the crypt-villus axis which showed the most shallow junction in control jejunum. This structural change is paralleled by a three-fold increase in epithelial resistance as previously measured by alternating current impedance analysis. Relative Na over Cl permeability (PNa:Cl) was obtained from dilution potential measurements. PNa:Cl was 1.50:1 in control jejunum and 1.35:1 in the blind loop (n.s.). Considering the cation selectivity of the tight junction, the increase in epithelial resistance in blind loops cannot be attributed to a collapse of the lateral intercellular space but is due to changes in tight junctional permeability resulting from structural alteration. The blind loop syndrome represents a further example of diminished epithelial ion transport and concomitant decrease in tight junction permeability, thus supporting the general concept of regulation of the tight junction in response to active transport activity.

[Microbial overgrowth syndrome after gastrectomy. Recent diagnostic aspects].

Blind loop syndrome is the most common syndrome of bacterial overgrowth following gastrectomy. We report two cases with diarrhea, steatorrhea, exudative enteropathy and major nutritional deficiency. Diagnosis was based on the breath test and aspirate analysis. Surgery with restoration of the duodenal continuity was the treatment. Patients with contraindications for surgery should be given prolonged antibiotic therapy which should be repeated if symptoms reoccur.

Ileostomy of the distal end of the bypassed intestine in a patient with jejunoileal bypass for obesity.

Ileostomy of the distal end of the bypassed segment of small intestine was done twenty-three months after a 28 to 20 cm (12 to 8 inch) end-to-end jejunoileal bypass for obesity (Scott operation) in a forty-eight year old white female, thus creating a Thiry fistula. Weight prior to jejunoileal bypass was 130 kg (287 pounds). Before ileostomy it had stabilized at 80.3 kg (177 pounds). Indications for ileostomy were three episodes of blind loop syndrome and three episodes of severe bleeding from the ileotransverse colostomy anastomotic site. Culture of the bypassed segment at laparotomy revealed bacteroides, clostridia, and other anaerobes as well as the usual aerobic large bowel flora. After ileostomy the bypassed segment contained no anaerobic bacteria. Daily fluid output from the ileostomy has decreased with time, averaging 436 ml per day for the first postileostomy month and 50 ml per day for the ninth month. Beneficial effects of the ileostomy include: (1) better sense of well being; (2) no further episodes of blind loop syndrome or intestinal bleeding; and (3) cessation of anal itching. Nine months after ileostomy, hyperoxaluria and acquired megacolon were present. Weight was 5.9 kg (13 pounds) greater than before ileostomy.

[Problems after surgery of the colon (author's transl)].

After surgery of the colon 3 types of sequelae may be observed: 1. Acute intra- and postoperative complications, as insufficiency of the anastomosis, ileus, and rebleeding; sequelae of these acute complications may be stenosis of the stenosis and intraabdominal adhesions. 2. Chronic postoperative syndromes like blind-loop syndrome, diarrhoea and/or continence problems, problems arising from an anus praeter, disturbances of sexual and bladder function. These symptoms occur rather rarely after partial resection of the rectum or amputation of the rectum. 3. Recurrence of the main disease, especially cancer disease, be it a local recurrence or metastasis. A well organized follow-up of cancer patients may increase survival time only in a few cases, but it definitely may improve quality of life by different means.

Bile salt regulation of fatty acid absorption and esterification in rat everted jejunal sacs in vitro and into thoracic duct lymph in vivo.

This study was performed to investigate whether the malabsorption of fat in the blind loop syndrome is due to the presence of free bile acids or to a deficiency of conjugated bile salts produced by bacterial degradation of normal bile salts, as well as to learn something of the mechanisms by which bile salts might regulate fat absorption. In the everted gut sac of the rat in vitro, conjugated bile salts were necessary for maximal rates of fatty acid esterification to triglycerides, whereas free bile acids inhibited this process even in the presence of physiologically normal or higher concentrations of conjugated bile salts. In contrast, in the living animal the addition of similar or higher concentrations of free bile acids to infusions of fatty acids in taurocholate micellar solutions produced no reduction in the amount of fatty acid absorbed into lymph or the amount of fatty acid esterified into lymph triglyceride. Both in vitro and in the living animal, reduction in the conjugated bile salt concentration reduced both the rate of fatty acid uptake by the intestine and the esterification into triglycerides. It is concluded that the steatorrhea of the blind loop syndrome or other conditions in which upper intestinal stasis allows bacterial proliferation is not due to presence of increased gut luminal concentrations of free bile acids, but rather is a consequence of lowered concentrations of conjugated bile salts.

Stagnant loop syndrome resulting from small-bowel irradiation injury and intestinal by-pass.

Stagnant or blind-loop syndrome includes vitamin B12 malabsorption, steatorrhea, and bacterial overgrowth of the small intestine. A case is presented to demonstrate this syndrome occurring after small-bowel irradiation injury with exaggeration postenterocolic by-pass. Alteration of normal small-bowel flora is basic to development of the stagnant-loop syndrome. Certain strains of bacteria as Bacteriodes and E. coli are capable of producing a malabsorption state. Definitive therapy for this syndrome developing after severe irradiation injury and intestinal by-pass includes antibiotics. Rapid symptomatic relief from diarrhea and improved malabsorption studies usually follow appropriate antibiotic therapy. Recolonization of the loop(s) with the offending bacterial species may produce exacerbation of symptoms. Since antibiotics are effective, recognition of this syndrome is important. Foul diarrheal stools should not be considered a necessary consequence of irradiation injury and intestinal by-pass.

Bacterial overgrowth syndrome without "blind loop": A cause for malnutrition in the elderly.

Probable bacterial contamination of the small bowel without an anatomical sump occurred in 5 elderly patients (age 68--94). They presented with severe general deterioration in health rather than with obvious features of malabsorption. This syndrome has not been clearly described before. Bacterial deconjugation of bile salts was indentified by the 14C-glycocholic-acid breath test. Investigations for other causes of malabsorption, including small-bowel biopsy and pancreatic scan, revealed no abnormality. After prolonged ill-health despite an adequate diet in hospital, all 5 subjects made a striking recovery after treatment with antibiotics. This condition may be quite common, particularly in malnourished elderly people.
