A new pedicled seromuscular flap technique for high-risk intestinal anastomoses

A new method for protecting intestinal anastomoses in patients at high risk of anastomotic dehiscence or fistula formation is described herein. This method involves raising a seromuscular flap on a pedicle from the stump of the intestine to be anastomosed. The anastomosis is performed, then covered with the seromuscular flap.     

Crohn's ileocolitis with initially superimposed cytomegalovirus infection, resembling intestinal tuberculosis]

We describe a case of 41-year-old Japanese man with Crohn's ileocolitis and cytomegalovirus infection, confirmed by histology of ileal ulcers. Although his colonoscopic and radiological features resembled those of intestinal tuberculosis, granulomas of typical Crohn's disease were evident on histology of biopsy specimens taken from the duodenum and colon. The lesions remain unchanged even after 1.5 years by oral administration of salazosulphapyridine 3g daily.     

Comparative study of the bacterial flora in both uterocervical and uterine regions

The relationship between indigenous bacterial floras in the lower genitals and the uterocervical region is of importance due to a barrier-like role against ascending infections through the mechanism of the localized protection at a boundary of the uterocervical region. Therefore, bacterial flora in the uterocervical and uterine regions was studied in cases for which gynecological operations were performed (n = 77). 1. Ratios of incidences of the detection of bacteria on the uterocervical and in the uterine regions were 50/77 (64.9%) and 6/77 (7.8%), respectively. When different age groups are compared, the detection ratio from the uterocervical region was high among patients in the 40 s, and all the cases in which bacteria were detected from the uterine region were in the 40 s. 2. Gram-positive bacteria were detected at a high ratio, and anaerobic bacteria were noted in the uterocervical region, and ratios of detection of Staphylococcus epidermidis, Lactobacillus sp. and Propionibacterium acnes were high. Six strains of Gram-positive bacteria and 1 strain of Candida sp. were noted in the uterine region. 3. When cefmetazole (CMZ) was administered for the prevention of the infections after these panhysterectomy cases examined here, no postoperative infectious diseases nor adverse reactions were noted.     

The effect of methamphetamine on serotonin and its metabolite in the suprachiasmatic nucleus: A microdialysis study

Summary The suprachiasmatic nucleus (SCN) has been identified as a major circadian pacemaker. Methamphetamine has been shown to modify the behavior of circadian rhythms. We detected extracellular serotonin (5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA) in the SCN in freely moving rats, using a microdialysis method, to investigate biochemical effects of methamphetamine in the SCN. Methamphetamine infusion into the SCN dose-dependently increased extracellular 5-HT and decreased extracellular 5-HIAA.     

Clinical and manometric evaluation of anorectal function following low anterior resection with low anastomotic line using an EEA™ stapler for rectal cancer

Anorectal function was evaluated in eight patients who had low anterior resection of the rectum with a low anastomotic line, using an EEA^™ stapler, with determination of function based on periodic manometric studies and clinical symptoms. Immediately following surgery all patients suffered from frequent bowel actions and soiling. These symptoms improved with time and most patients could enjoy almost normal daily life by the sixth postoperative month. One month after surgery, anal canal resting pressure and maximum squeeze pressure were significantly reduced and rectoanal inhibitory reflex was absent; neither showed a distinct tendency to improve thereafter. Rectal sensation and reservoir capacity, which also were seriously impaired, recovered satisfactorily by the time of the six-month examination. This suggests that an improvement of clinical symptoms following this operation is dependent upon the recovery of reservoir capacity and sensation of the neorectum, and that this operative procedure is a functionally acceptable option for low rectal cancer.     

Lacunar skull deformity and hydrocephalus in infants with myelomeningocele: is lacunar skull deformity a predictor of hydrocephalus development?

Objects We evaluated whether the presence of lacunar skull deformity (LSD) with myelomeningocele is a predictive factor for subsequent hydrocephalus development. Materials and methods We reviewed the clinical and radiological records of 18 infants with myelomeningocele, divided the patients into groups with (group A, n=9) and without (group B, n=9) ventriculomegaly at birth and assessed whether the presence of LSD was predictive of the necessity for ventriculoperitoneal shunt (VPS) placement. Results LSD was present in five group A patients. All nine group A patients underwent VPS placement. Among the group B patients, five had LSD; they underwent VPS placement. A significantly higher proportion of those with ventricle enlargement or LSD at birth required VPS placement (p=0.0001). Conclusion Adding to the ventriculomegaly at birth, the presence of LSD alerts to the necessity to monitor these infants closely to determine the necessity for VPS placement.
