Tissue adhesives for repairing inguinal hernia: a preliminary study

AIM: To investigate the efficacy of tissue adhesives for closing the orifice of the inguinal hernia sac (IHS) as an alternative method for treating inguinal hernia. METHODS: Five-week-old male Lewis rats (n=4) were used, because Lewis rats have a large patent IHS. The rats were divided into 9 groups (n=6 in each) according to the type of tissue adhesive used: G1, fibrin glue (Beriplast); G1b, Beriplast plus blood; G2, microfibrillar collagen hemostat (Avitene); G2b, Avitene plus blood; G3, fibrinogen-based sealant (TachoComb); G3b, TachoComb plus blood; G4, synthetic absorbable sealant (Advaseal); G5, bilateral single port laparoscopic injection of octylcyanoacrylate (Dermabond); and G6, sham operation (control group). In G1-G4, surgery was performed through a midline lower abdominal incision. In G5, a 5-mm laparoscope was inserted in the epigastrium, a fine catheter was passed through the side port of the laparoscope into the right HIS, and 0.2 mL Dermabond was injected. The left IHS was treated in the same way. All rats were sacrificed 3 months after treatment, and IHS patency was examined macroscopically. All rats in G5 and G6 were mated 50 days after treatment to check fertility. RESULTS: All rats survived until sacrifice. At sacrifice, all IHS were patent in G6. All IHS were also patent in G1-G4, but all IHS were closed at the internal ring in G5. In G5 there were no adhesions between the orifice of the closed sac and the small bowel in 5/6, and only minor adhesions in 1/6. G5 fertility (5/6: 83%) was the same as for the control group (G6). CONCLUSION: Our results suggest that laparoscopic injection of Db into the IHS is simple, safe, reliable, virtually scarless, and may be a reasonable alternative to standard open surgical inguinal hernia repair.     

Pharmacological properties of procaterol, a newly synthetized, specific beta 2-adrenoceptor stimulant. Part I. Effects on the CNS (author's transl)]

Effects of procaterol (PRO) on the CNS were investigated in comparison with those of salbutamol (SAL) and isoproterenol (ISO). PRO, 15 to 50 mg/kg given subcutaneously suppressed spontaneous movement in mice, rats and rabbits and with a large dose, 1000 mg/kg, the animals became quiet and immobile. In dogs, PRO produced similar symptoms and in addition, there was nausea and vomiting. The animals recovered within 3--8 hours. ID50's in depressing spontaneous movement were 20.2 and 245 mg/kg for PRO, 51.1 and 133 mg/kg for SAL and 2.37 and 143 mg/kg for ISO, respectively, both by the subcutaneous and oral routes of administration. Methamphetamine induced increase in motility and fighting behavior was also suppressed by PRO when similar doses were given. PRO had no effect on coordinating movement, halothane anesthesia, drug and electric stimulation induced convulsions and body temperature, and there was no muscle relaxant action. However, PRO in large doses prolonged sleeping time with hexobarbital. The analgesic effect of PRO was not observed with Haffner's and Landall Selitto's methods but acetic acid induced writhing was suppressed by PRO. PRO had little effect on spontaneous EEGs either cortical or from deep structures, and EEG arousal responses. The effects of PRO on the CNS were slight and nonspecific, and similar to those of SAL and ISO.     

Long-term therapy with Robaveron tablet (KN-7) for urinary disturbance

Sixteen patients with benign prostatic hypertrophy (BPH, 5 cases) and neurogenic bladder (NB, 11 cases) were treated with Robaveron tablets (KN-7) containing an extract of swine prostate gland 20 mg/T. at the dose of 2 tablets t.i.d. for a long term of 6-33 months. Evaluation of drug efficacy and safety were based on decrease of residual urine, improvement of subjective symptoms, complaints of side effects and clinical laboratory tests recorded every three months. Significant decrease of residual urine rate and good improvement of various subjective symptoms such as difficulty in urination, pollakisuria, urinary incontinence, etc. were obtained and maintained. The overall effectiveness, rated as slightly improved or better on the final evaluation of these cases was 68.8%. No cases of side effects or abnormal changes in the laboratory tests directly due to the test drug were observed. Robaveron tablet is both safe and effective for the long-term therapy of urinary disturbance.     

The effects of repeated thermal therapy for two patients with chronic fatigue syndrome

OBJECTIVE: This paper describes the successful treatment of two patients with chronic fatigue syndrome (CFS) using repeated thermal therapy. METHODS: Two patients with CFS underwent treatment with prednisolone (PSL), with no satisfactory effect. They were subjected to thermal therapy that consisted of a far-infrared ray dry sauna at 60 degrees C and postsauna warming. The therapy was performed once a day, for a total of 35 sessions. After discharge, these subjects continued the therapy once or twice a week on an outpatient basis for 1 year. RESULTS: Symptoms such as fatigue, pain, sleep disturbance, and low-grade fever were dramatically improved after 15 to 25 sessions of thermal therapy. Although PSL administration was discontinued, the subjects showed no relapse or exacerbation of symptoms during the first year after discharge. The patients became socially rehabilitated 6 months after discharge. CONCLUSIONS: These results suggest that repeated thermal therapy might be a promising method for the treatment of CFS.     

Strongest correlation of HbA(1c) with 1-month-earlier glucose levels in type 2 diabetes

We examined the correlations of hemoglobin A(1c) (HbA(1c)) with each plasma glucose (PG) level obtained at 0 (the same day), 1 and 2 month(s) prior to HbA(1c) determination. Data were from glycemic profiles of four patients of type 2 diabetes mellitus treated with tablets whose HbA(1c) and pre- and post-breakfast PG levels were monitored each month. There was no significant difference in the correlation coefficients in cases 1 and 2, who presented with linear glycemic time courses. In contrast, HbA(1c) correlated with 1-month-earlier pre-breakfast PG level more strongly than 2-month-earlier post-breakfast PG level in cases 3 and 4, and than same-day post-breakfast PG level in case 3 (P<0.05, ANOVA). The cases 3 and 4 presented with fluctuating glycemic time courses. Samples were separated into upslope's and downslope's sections according to HbA(1c) fluctuation in the latter two cases. Reflecting around the 1-month lag between HbA(1c) and PG, the two sections' regression lines for PG versus HbA(1c) corresponded in the only samples related to 1-month-earlier pre- and post-breakfast PG (t-test). In conclusion, it appears that pre- and post-breakfast PG levels are the most reliable predictors of 1-month-later HbA(1c) in type 2 diabetic outpatients who undergo medical examinations every month.     

Primary cardiac malignant lymphoma diagnosed intraoperatively during aortic valve repair; report of a case

A 58-year-old male who complained of chest oppression on effort was diagnosed as aortic regurgitation by echocardiography. The cardiac catheterization was showed moderate aortic regurgitation. He was referred to our hospital for aortic valve replacement. We considered preoperatively that the aortic regurgitation is due to infective endocarditis or aortitis syndrome. We have not noticed cardiac tumor at all until aortic valve replacement. Postoperative pathological diagnosis of the tumor was malignant lymphoma. The tumor had a characteristic architecture of a cardiac MICE (mesothelial/monocytic incidental cardiac excrescence). After the operation, additional chemotherapy using doxorubicin and cysplatin was performed. The patient has been doing well for 5 years after operation.     

Experience with laparoscopic splenectomy for ABO-incompatible living related renal transplantation

PURPOSE: To determine whether laparoscopic splenectomy for ABO-incompatible living related renal transplantation is safe and effective. PATIENTS AND METHODS: From July 2000 to May 2002, laparoscopic splenectomy was performed on the day of transplantation in 10 patients undergoing ABO-incompatible living related renal transplantation. Perioperative and postoperative data, including operative time, blood loss, and complications, were evaluated. RESULTS: The mean operative time was 79 minutes. Intraoperative blood loss ranged from 25 mL to 600 mL (mean 130 mL). Transfusion was not required in any case. One patient required open conversion because of bleeding from the splenic hilum. The serum amylase value was slightly elevated postoperatively in four patients but normalized with conservative treatment. One patient had bleeding from a trocar port wound, which was likewise treated conservatively. No complications, including postoperative renal dysfunction or fatal infections, that were considered attributable to the laparoscopic procedure were noted. CONCLUSIONS: Laparoscopic splenectomy performed simultaneously with renal transplantation is a safe and efficacious procedure for ABO-incompatible living related renal transplantation.     

Use of transpelvic rectus abdominis musculocutaneous flap for anal cancer salvage surgery

BACKGROUND: Perineal wounds following abdominoperineal resection (APR), for persistent or locally recurrent anal cancer, are associated with poor healing secondary to irradiation therapy. The results of APR combined with a vertical rectus abdominis musculocutaneous (VRAM) flap transposed transpelvically to cover the perineal defect are presented. METHODS: Between 1994 and 2000, 105 patients were diagnosed and treated for anal cancer. Twenty-two (21 per cent) underwent a salvage operation owing to persistent or locally recurrent disease. In eight patients, before 1996, the perineum was closed primarily with serious wound complications in five. In the final 14 patients, primary perineal reconstruction with a VRAM flap was performed. RESULTS: Median age was 65.5 (range 45-78) years. Median follow-up was 14.5 (range 3-41) months. There were no flap-related complications and primary healing was achieved in all patients. Median hospital stay was 17 (range 14-72) days. There were two major complications related to the laparotomy and abdominal closure. CONCLUSION: Combining the salvage operation with a VRAM flap facilitates primary healing after surgical treatment for persistent or locally recurrent anal cancer. A single-stage primary reconstructive procedure is feasible, with an acceptable complication rate and high level of patient satisfaction.
