Accelerated ventricular rhythm in the newborn

Accelerated ventricular rhythm was observed in two newborn infants. Neither of them had any causative clinical symptoms for the ventricular arrhythmia. The arrhythmia disappeared when the infants were 18 days and 45 days old, respectively. Arrhythmia was noted in the fetal period, especially in case 1.     

Fetal valproate syndrome with reduction deformity of limb

A case is reported of a female infant having multiple anomalies, including epicanthic folds, hypertelorism, bifid nasal bridge, shallow philtrum, low-set ears, brain atrophy, cleft palate, hemangioma on the chest, and reduction deformity of the left upper limb. This is the first case where an infant who was exposed to sodium valproate intra-uterine has a reduction deformity of the upper limb.     

Urodynamic evaluation of a suspension technique for rapid recovery of continence after radical retropubic prostatectomy

BACKGROUND: We investigated urodynamic findings involved in the rapid recovery of urinary continence after radical retropubic prostatectomy with a suspension technique. METHODS: A total of 45 consecutive patients (mean age 67.6 years) who had undergone radical retropubic prostatectomy for localized prostate cancer were evaluated with multichannel urodynamics including the maximal urethral pressure (MUP), functional urethral length (FUL), maximal cystometric capacity (MCC) and abdominal leak point pressure (ALPP) at base line, 1 week, 1 month, and 3 months postoperatively. The suspension of vesicourethral anastomosis preserving anterior attachments of puboprostatic ligaments to pubic bone was performed in 33 patients. Twelve patients did not undergo the suspension technique. RESULTS: The continence rates at 1 week, 1 month, and 3 months after radical prostatectomy in the suspension group were significantly higher than those in the non-suspension group: 67% versus 0% at 1 week (P < 0.001), 82% versus 25% at 1 month (P < 0.001), and 91% versus 50% at 3 months (P < 0.01), respectively. Postoperative ALPP at all points of measurement was significantly higher in the suspension group than in the non-suspension group (P < 0.0002). There was no difference in MUP, FUL or MCC at each point following radical prostatectomy between the two groups. CONCLUSIONS: These observations suggest that preserving anterior attachments of puboprostatic ligaments to pubic bone and fixation of urethral hyper-mobility by the suspension of vesicourethral anastomosis promotes rapid recovery of urinary continence after radical retropubic prostatectomy.     

Laparoscopy Assisted Colectomy with Extracorporeal Anastomosis

Abstract: Laparoscopy assisted colectomy with extracorporeal anastomosis was carried out in five patients. In three patients, the lesions were carcinoma with submucosal invasion and the histological results of the polypectomy specimen indicated the necessity of the subsequent colectomy. In the other two patients the lesions were either adenoma or carcinoma in adenoma. Under pneumoperitoneum, mobilization of the colon was performed using the laparoscopic technique. In three patients the mesenteric vessels of a segment of the colon were ligated and divided extracorporeally. In two patients the mesenteric vessels were clipped and divided intracorporeally. In all cases, extracorporeal resection of the colon and hand suture anastomosis were performed. Surgery time ranged from 3 hours and 20 minutes to 4 hours and 50 minutes. No postoperative complications were experinced. Four patients began to walk on the first postoperative day. Postoperative administration of analgesics was needed in four patients for two days or less after the operation. In all but one case, bowel sounds were audible from the first post-operative day onwards. In only one patient was the postoperative recovery delayed. Although sufficient future studies should be accumulated to confirm the advantages of this procedure, we can expect that laparoscopy assisted colectomy will become a useful procedure for benign and early malignant lesions in which colonoscopic removal was not possible or was suspected to be insufficient.

Hepatocellular carcinoma in 13 patients with hepatitis C virus-associated chronic hepatitis

Abstract Thirteen of 81 patients with chronic hepatitis and positive hepatitis C virus (HCV) antibody developed hepatocellular carcinoma (HCC) during a follow-up period of 54 ± 38 months. The histopathological findings in HCC-bearing liver in these patients included six cases of chronic persistent hepatitis [CPH; mean hepatitis activity index (HAI) score: 5.8] and seven cases of chronic aggressive hepatitis (CAH) 2A, or 2B (HAI) score: 13.6). Multiple biopsies of the liver in six cases revealed that five cases, including four with CPH at the time of HCC diagnosis, previously had histopathological findings identical to CAH 2A, and another case constantly had CPH during the 8-year follow-up. These findings suggest that HCV-associated HCC can occur even in patients with HCV antibody positivity and inactive or mild chronic hepatitis. This is of interest in the pathogenetic mechanisms of HCV-associated HCC.     

Human Chorionic Gonadotropin-Like Substance (hCG-LS)-Producing Urothelial Carcinoma: Immunohistological Location of hCG-LS

We experienced three cases of human chorionic gonadotropin-likesubstance (hCG-LS)-producing tumors of urothelial carcinoma(two cases of renal pelvic tumor and one case of bladder tumor),which revealed high levels of luteinizing hormone in the urine,serum and tissue. The pathological diagnosis was transitionalcell carcinoma, grade III (two cases) and undifferentiated carcinoma(one case). The present study is aimed to determine the locationof hCG-LS in tumor cells by an immunohistochemical approach.By the immuno peroxidase technique using anti-hCG-ßserum, hCG-LS was located in the cytoplasm of anaplastic giantcells and trophoblastic-like cells. In two cases the diseaseprogressed rapidly, to terminate fatally in a short time. hCG-LSproducing urothelial carcinomas generally seem to contain anaplasticgiant cells and/or trophoblastic-like cells, and are suggestiveof poor prognosis.
