The differences in quality of life (QOL) impairment due to urinary incontinence between elderly and younger women were evaluated using King's Health Questionnaire (KHQ) and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). The subjects were 313 women who consulted the Women's Urinary Incontinence Clinic of Saiseikai Central Hospital between March, 2005 and January, 2008. They were divided into those below or above the cut-off age of 55, 60 or 65 years. The difference in QOL impairment was greatest when the cut-off age was 60 years. Similar comparisons were made by dividing the subjects into those aged 65-74 years and those aged 75 years and above, but no significant difference was noted in the score of any KHQ domain or ICIQ-SF between the two groups. The stress urinary incontinence occurred in younger women and caused the severest impairment. The response rate to KHQ in this study was low especially in the elderly, but that to ICIQ-SF was as high in the elderly as in younger age group. Social activities and lifestyle change around age 60 were considered to be associated with the change of QOL impairment in women with urinary incontinence. The stress urinary incontinence caused the severest impairment. KHQ was often difficult for the elderly to complete, but, ICIQ-SF seemed to be easy.

A 49-year-old male was referred to our hospital with the chief complaint of gross hematuria. We performed cystoscopy, and found a solid tumor at the dome of the bladder. Sagittal magnetic resonance imaging revealed an extravesical tumor at the position of the urachus. Transurethral resection of bladder tumor was performed. A solid tumor at the dome and two papillary tumors at the right lateral region of the bladder were observed. A pathological examination revealed adenocarcinoma from the solid tumor and urothelial carcinoma from the papillary tumors. Under a diagnosis of double cancer, adenocarcinoma of the urachus and urothelial carcinoma of bladder, we performed a total cystectomy, neobladder and total resection of the urachus.

An 84-year-old female was referred to our hospital to be examined for left hydronephrosis. Abdominal pelvic computed tomography and ureteroscopy showed an obstructing mass in the left ureter. A biopsy of the mass revealed the presence of small cell carcinoma. A left nephroureterectomy were thus performed.

A 63-year-old male presented with an intravesical foreign body. We could not remove it by a transurethral operation. We performed open surgery, and found the urinary bladder to be perforated by a foreign body which invaded the peritoneal cavity. To our knowledge, there were 10 similar cases in Japan.

Congenital myasthenic syndromes (CMS) are rare heterogeneous disorders of neurotransmission caused by genetic defects of neuromuscular junction molecules. While CMS patients have been reported worldwide, in Japan there have been only a few descriptions of adult CMS patients with acetylcholinesterase (AChE) deficiency and slow channel syndrome. Herein, we report a Japanese CMS patient with acetylcholine receptor (AChR) deficiency, diagnosed during childhood, and our treatment approach to the patient. This 13-year-old Japanese boy had had severe myasthenic symptoms since infancy. Ptosis, his first symptom, appeared at 5 months and nasal voice was recognized at 2 years of age. AchR and anti-muscle-specific tyrosine kinase (Musk) antibody remained negative. A positive tensilon test and decremental response on electromyogram supported the diagnosis of sero-negative myasthenia gravis. Despite thymectomy and strong immunosuppressive therapy including steroid pulse and FK 506, he gradually deteriorated and became wheelchair bound. Genetic analyses for AchR, Rapsyn, Musk and AChE were negative. At age 11 years, a muscle biopsy was performed in the deltoid muscle for neuromuscular junction sampling. Electron microscopic and confocal microscopic analysis of endplates showed almost complete loss of AChR and the diagnosis of CMS with AChR deficiency was confirmed. All immunosuppressive therapies were discontinued. Instead, we started Ubretide and 3,4-diaminopyridine (DAP) after obtaining informed consent. Although not approved in Japan for this use, 3,4-DAP is reportedly effective in refractory cases of CMS. The patient experienced no side effects. Despite all of the objective data were improving, his subjective symptoms and ADL remained poor. There are still many challenges in the treatment of the patient.
