Congenital quadricuspid aortic valve with tetralogy of Fallot and pulmonary atresia

We report the case of a 4-year-old girl who had quadricuspid aortic valve regurgitation with tetralogy of Fallot and pulmonary atresia. This combination is very uncommon. Aortic valve replacement was performed successfully due to aortic regurgitation which had progressed one year after the total repair. The dilated aortic annulus plus quadricuspid aortic valve may result in progressive aortic regurgitation for a short period.     

Spontaneous Uterine Venous Rupture During Labour: A Case Report With Postoperative Ultrasonographic Findings

EDITORIAL COMMENT: We accepted this case for publication to remind readers that although uterine rupture during labour in a primigravida is extremely uncommon it does occur, or at any rate nulliparas can develop abdominal pain and shock in labour with a haemoperitoneum resulting from a tear in a vein in the lower posterior uterine wall. When one sees the hugely dilated uterine and ovarian venous plexuses at Caesarean section it is easy to believe that bleeding from such a vessel during labour could be prodigious. This case suggests that a dilated vein with blood flow derangements may be the cause. Nonetheless, as the authors warn us, the necessary response is not a precise diagnosis, but rapid laparotomy.

Antibodies to HTLV-1 in saliva of seropositive individuals from Japan

Secretory antibodies protect mucosal surfaces against transmission of many viruses. Human T-lymphotropic Virus, Type I (HTLV-I) is transmitted via blood products and via sexual contact across mucosal surfaces. We investigated the presence of HTLV-I-specific antibodies in whole saliva samples from 10 seronegative and 28 seropositive volunteers from a hospital in southern Japan. Antibodies directed to HTLV-I antigens were found in the salivas from 22 of 28 (79%) of the seropositive subjects. None of the seronegative individuals showed evidence of salivary antibodies. Antibodies directed to the envelope antigens of the virus were found in 21 of 22 positive saliva samples. Secretory antibodies may be important in preventing mucosal transmission.     

Resected cases of middle lobe primary cancer

Of 200 lung cancer lesions resected in our hospital, there were 15 cases (7.5%) with middle lobe origin. The histological types were adenocarcinoma in 13 patients (4 patients with alveolar cell carcinoma), squamous cell carcinoma in one and large cell carcinoma in one. These patients were classified into two groups according to the type of operation they received and each group was evaluated. Group I (resection of the middle lobe) included 8 patients. Each one of Stage IIIB and Stage IV received the operation to improve their symptoms. The six patients of Stage I received only middle lobectomy as absolute curable cases. Group II (resection of the middle and lower lobes) included 7 patients, who had preoperative diagnosis of stage III. Two of them were postoperatively found to be cases of Stage I and Stage II. Although it was still short-term, the follow-up evaluation proved that these patients survived without local recurrence and distant metastasis, except for two with pleural dissemination and one with cerebral metastasis, who had received lobectomy as palliative operation. No difference was observed between the two groups receiving different types of operation.     

Percutaneous removal of renal and upper ureteral stones: clinical results and complications of 103 cases

We report the results and complications of 103 consecutive patients who underwent percutaneous removal of renal and ureteral stones. The overall clinical success rate was 80.6%. For the recent 33 cases in which UL-arm fluoroscopy was used, however, the success rate was as high as 87.9%, which was considered to be due to easier establishment of percutaneous direct access. The most common complications were bleeding (18.5%), extravasation (15.5%) and fever (9.7%). Four cases with significant bleeding required arteriography, but there were no sign of arteriovenous fistula nor pseudoaneurysms in any cases. To study renal parenchymal damage in the percutaneous procedures, plasma renin activities (PRA) were compared in 54 cases after six months. However, significant elevation of PRA did not occur in any case.     

Endourologic management of filling defect in renal pelvis: limited value of cold cup biopsy

A fifty-six-year-old woman underwent transurethral ureterorenoscopy and cold cup biopsy for evaluation of a filling defect of the left renal pelvis. The pathology indicated a benign lesion, and percutaneous resection was done with the nephroresectoscope. However, the pathologic diagnosis of the resected tissue showed it to be transitional cell carcinoma, grade I. Consequently we performed a nephroureterectomy with excision of a cuff of bladder and the nephrostomy tract. Residual tumor was found in deep layer of the renal pelvis. The implication from this case in defining the indications for endourologic management of tumors is considered.
