The ileoanal J pouch: radiographic evaluation

Endorectal ileoanal pull-through offers an attractive alternative to proctocolectomy and ileostomy for patients with ulcerative colitis, Gardner syndrome, and familial polyposis. To our knowledge, a careful radiographic analysis of the ileum, ileal pouch, and ileoanal anastomosis after ileoanal pull-through has not been reported. Thirty-two patients with ulcerative colitis, Gardner syndrome, and familial polyposis underwent colectomy, mucosal proctectomy, and endorectal ileoanal pull-through of a 15-cm ileal "J" pouch and loop ileostomy. Twenty-five (78%) of 32 of all the pouches radiographically demonstrated spiral folds extending from the middle of the pouch to the pectinate line. Other radiographic features included a mesenteric mass effect, pseudopolyps, and a central lucency that indicated intrapouch sutures. Radiographs provide useful information in the postoperative management of the ileal pull-through.     

Pulmonary artery banding: analysis of a 25-year experience

A 25-year experience (May 1962 through April 1987) with pulmonary artery banding in 183 patients was reviewed and analyzed. Pulmonary artery banding was performed in a heterogeneous group of patients aged two days to 60 months (median, 10 weeks; mean, 21.8 weeks) and weighing 1.4 to 13.8 kg (mean, 4.2 kg). Diagnosis was ventricular septal defect in 76 (41.5%) and atrioventricular communis in 41 (22.4%). Pulmonary artery banding was also used in patients with d-transposition of the great vessels with ventricular septal defect, double-outlet right ventricle, univentricular heart, tricuspid atresia, and truncus arteriosus. Early death occurred in 39 of 175 patients who underwent pulmonary artery banding at Ochsner Foundation Hospital (22.3%). Definitive operation has been performed in 37 of the patients who underwent pulmonary artery banding since 1979 with excellent outcome in 32 (86.5%). Pulmonary artery banding is a useful palliative procedure for a diverse group of patients with congenital cardiac anomalies and unrestricted pulmonary blood flow. With improved results of primary repair of intracardiac anomalies in small infants, however, pulmonary artery banding should be reserved for severely ill patients with complex lesions not amenable to early definitive correction. Currently, pulmonary artery banding is indicated in patients with excessive pulmonary blood flow and single ventricle or tricuspid atresia. Pulmonary artery banding is also appropriate in certain patients with atrioventricular communis and in patients with muscular or multiple ventricular septal defects. Pulmonary artery banding is an option in patients with ventricular septal defect and coarctation of the aorta.     

The association between Helicobacter pylori infection and functional dyspepsia in patients with irritable bowel syndrome

OBJECTIVE: Irritable bowel syndrome (IBS) is associated with an exaggerated response to a variety of physiological and nonphysiological gastrointestinal stimuli. Many patients with IBS also have functional dyspepsia. Our aim was to examine the hypothesis that Helicobacter pylori (H. pylori) infection may predispose IBS patients to functional dyspepsia. METHODS: In 69 IBS patients, dyspeptic symptoms, H. pylori status, and sociodemographic and psychological variables (perceived stress, trait anxiety, and depression) were assessed. Sociodemographic and psychological variables were also evaluated in 52 control subjects. RESULTS: Mean scores for perceived stress (17.1 +/- 6.0 vs 14.9 +/- 6.0, p = 0.05), trait anxiety (45.6 +/- 9.1 vs 41.1 +/- 7.8, p = 0.004) and depression (9.9 +/- 8.4 vs 5.0 +/- 5.5, p = 0.0002) were higher in IBS patients than in controls. In all, 33 of the 69 patients (47.8%) had H. pylori infection, and this was associated with relevant symptoms of epigastric pain (odds ratio [OR] = 6.77, 95% confidence interval [CI] 1.89-24.3) and postprandial upper abdominal fullness (OR = 4.23, 95% CI 1.38-13.2). H. pylori infection and female gender were independent predictors of the presence of relevant dyspepsia (OR = 8.31, 95% CI 2.35-29.5 and 6.06, 95% CI 1.71-21.5, respectively). Symptom intensity was associated with the level of perceived stress (total relevant symptom number > or =3 vs <3, OR = 1.16 per point on a 40-point perceived stress scale, 95% CI 1.01-1.34). CONCLUSIONS: In IBS patients, the presence of dyspepsia is associated with H. pylori infection, female gender, and perceived stress.     

Suicidal bupropion ingestions in adolescents: increased morbidity compared with other antidepressants

Objective: Bupropion is often categorized as a newer generation antidepressant and assessed with serotonin reuptake inhibitors as a lower risk than older tricyclic antidepressants (TCAs). The objective of this study was to compare outcomes in adolescent suicide from ingestions between bupropion and TCA medications.

Study design: An analysis of the National Poison Data System for exposures coded “suspected suicide” in adolescents (age: 13–19) was undertaken for the years 2013–2016 and included TCAs or bupropion. We compared clinical effects, therapies and medical outcomes.

Results: Over the four-year period there were 2253 bupropion and 1496 TCA adolescent suspected suicide calls. There was a significant linear increase in bupropion ingestions over the four years. Across all years, there were on average 189.2 (95% CI: 58.1–320.4; p?=?.01) more ingestions of bupropion than TCA. When comparing bupropion to a TCA, ingestions of bupropion were significantly more likely to be accompanied by seizure (30.7% vs 3.9%; p?p?p?p?p?Conclusions: Adolescents who overdose on a single medication in a suicide attempt with bupropion have a statistically significant higher incidence of major outcomes and seizures. The risks of bupropion as a potential means of suicidal gesture by overdose must be considered, and weighed against its benefits and side effect profile when choosing an appropriate agent for the treatment of depression in adolescents.     

Relationship between esophageal motility and transit in patients with type I diabetes mellitus

OBJECTIVES: Delayed esophageal transit and abnormal esophageal motility occur frequently in patients with long-standing diabetes mellitus. However, the relationship between transit and motility has not been assessed directly. The aim of this study was to investigate the patterns of esophageal motor function documented previously to have delayed esophageal emptying and esophageal transit in patients with insulin-dependent diabetes mellitus. METHODS: Concurrent esophageal manometry and radionuclide measurement of transit of liquids and solids were performed in 11 patients with insulin-dependent diabetes, 10 age-matched controls, and 11 young normal subjects. RESULTS: Patients with diabetes had a greater frequency of transit hold-up for solids (96%) than did older controls (65%) or young normals (42%) (p < 0.001), whereas the frequency of transit hold-up for liquid boluses was similar among the three groups (diabetics, 36%; older normals, 17%; young normals, 17%). The major mechanism responsible for bolus hold-up in diabetics was peristaltic failure (liquid, 52%; solid, 67%) and the level of hold-up coincided with the level of bolus hold-up for 10/11 liquid and 27/28 solid boluses. CONCLUSIONS: In insulin-dependent diabetes, retarded esophageal transit usually reflects either peristaltic failure or focal low-amplitude pressure waves.     

Detached ciliary tufts mistaken for peritoneal parasites: a warning

Detached ciliary tufts of columnar epithelial cells from the female genital tract may be mistakenly identified as protozoa when examined in wet mounts of fluid specimens in the laboratory because of their appearance and motility, although they are generally identified correctly in fixed specimens prepared for cytologic examination. A case of such mistaken identity in specimens from a gynecologic patient was documented, and the literature on ciliary tufts was reviewed. Infectious disease and gynecology consultants should be alert to the potential confusion arising from the presence of ciliary tufts in body fluids.
