Erosion of a penile prosthesis due to an indwelling urethral catheter as a late complication.

A case of erosion of a penile prosthesis caused by indwelling of a catheter in the urethra is reported. A 73-year-old man had maintained sexual intercourse with penile prostheses (Jonas prosthesis, 19 cm) for 11 years without any complications until he developed cerebral infarction. One month after starting an indwelling urethral catheter in a neurosurgery clinic, the left-side penile prosthesis eroded from the area of the fossa navicularis, and was immediately removed. This type of complication is not unusual in patients with a neurogenic bladder. However, it is not well recognized in patients who suddenly develop a neurogenic bladder following a long-term uneventful period after the implantation of penile prostheses. Therefore, urologists should inform patients who receive this type of treatment that erosion of the prosthesis may develop when they need an indwelling urethral catheter as a late complication.

Complications of Stamey needle suspension for female stress urinary incontinence.

INTRODUCTION: The Stamey bladder neck suspension for stress urinary incontinence in females is thought to be an excellent procedure. However, recent studies revealed that complications of this procedure have not been negligible. In this retrospective study, complications of the Stamey needle bladder neck suspension were examined. MATERIALS AND METHODS: The Stamey procedure was performed either alone or in combination with anterior colporrhaphy for 86 female patients with stress urinary incontinence between 1989 and 1999. The mean follow-up period was 37.6 months and the mean age was 59.1 years. We studied the complications postoperatively pointed out by patients' complaint and image examination. RESULTS: The overall incidence of complications was 37.2%. Voiding difficulties and lower abdominal pain were present in 15 cases, respectively. We experienced 2 unusual cases in whom suspensory stitches had to be removed due to abdominal pain. CONCLUSIONS: Although the Stamey bladder neck suspension is thought to be an excellent procedure for stress urinary incontinence, surgeons should beware of possible complications and be alert of the symptoms, such as abdominal pain and bladder irritation.

Intralobar pulmonary sequestration presenting increased serum CA19-9 and CA125.

A 39-year-old man was admitted to our hospital for further evaluation of a consolidated shadow and clarification of the cause of serum tumor marker elevation (CA19-9 496.2 U/ml, CA125 160.6 U/ml). Chest computed tomography revealed a well-defined homogeneous nodule in the left S(10). Angiography showed one aberrant artery, branching from the ascending aorta. Intralobar pulmonary sequestration was diagnosed and the sequestrated lung was resected. Microscopic findings of the sequestrated lung showed a mucus-containing cystically dilated bronchus, which was covered with ciliated cylindrical epithelium. Immunohistochemical staining showed positive staining for CA19-9 and CA125 in both the ciliated cylindrical epithelium and mucus. Serum values of tumor markers returned to their normal range after surgery.

[Comparative study of bone resorption markers for the diagnosis of bone metastasis in lung cancer].

NTx and I CTP, a metabolite of type I collagen, were compared as to their usefulness as indicators of bone metastasis in lung cancer. The NTx level was significantly higher in lung cancer patients with bone metastasis (107.9 +/- 56.1 nM BCE/mM) than in those without it (p < 0.0001), as was the I CTP level (10.0 +/- 6.5 ng/ml; p < 0.0001). The Z scores of NTx and I CTP were 2.37 and 2.04, respectively, indicating that NTx is superior to I CTP in sensitivity to bone metastasis because of its higher Z score and its higher area under the ROC curve. The cutoff values of these markers were set to produce the highest accuracy/sensitivity rates and to make possible the highest diagnostic efficiency, and then the odds ratios at these cutoff values were calculated. The odds ratios of NTx and I CTP at cutoff values for the highest accuracy were 66.3 and 12.6, respectively; those offering the highest diagnostic efficiency were 46.5 and 10.0, respectively. These results indicated that NTx offers better prediction of bone metastasis in lung cancer than does I CTP.

[A case of immotile-dyskinetic cilia syndrome responding to clenbuterol hydrochloride and azithromycin].

In this case, a 30-year-old man had been treated for chronic sinusitis and bronchiectasis since 2000, and presented at our outpatient clinic in May 2001 with chief complaints of massive yellow sputum expectoration and dyspnea. After he was admitted by our hospital, Pseudomonas aeruginosa bacteria were isolated at the rate of 10(8)/ml from his sputum culture. In electron-microscopic observation, the cilia of the bronchial epithelium were found to lack dynein arms. Semen examination revealed decreased sperm motility. Thus, the following diagnosis was made: diffuse bronchiectasis associated with the immotile-dyskinetic cilia syndrome, complicated with a P. aeruginosa infection. After the airway infection was ameliorated, 40 mg/day of clenbuterol hydrochloride was administered in combination with 250 mg of azithromycin, which was given twice a week, and which led to a markedly decreased frequency of exacerbation of airway infection. Moreover, chest CT scanning and respiratory function testing also indicated improvements. It was hypothesized that the decreased cilia motility due to P. aeruginosa-produced pyocyanin would be ameliorated with a b2 stimulant, and the inhibitory effect of a macrolide on the P. aeruginosa biofilm and production of pyocyanin would also be involved in the improvement of this case.

[A case of diffuse malignant mesothelioma of the pleura with bilateral chylothorax].

We describe a case of bilateral chylothorax with malignant pleural mesothelioma. A 41-year-old woman was admitted to our hospital because of dyspnea. She had no history of exposure to asbestos. A chest radiograph and chest computed tomogram (CT) on admission revealed massive bilateral pleural effusion and a large tumor with pleural thickening in the left lateral and anterior parts of the pleura and mediastinum. Biochemical tests of pleural fluid revealed chyle. Two years before, she had been diagnosed through histological and histochemical examinations as having diffuse malignant pleural mesothelioma of the epithelial type. Chest-tube drainage was performed, and pleurodesis was induced by the intrathoracic injection of OK-432 at 10 KE per dose. The chylothorax disappeared after pleurodesis. To date, reports of malignant mesothelioma with nontraumatic chylothorax have been rare.
