Endoscope-assisted minilaparotomic radical retropubic prostatectomy

OBJECTIVE: To assess the clinical efficacy of endoscope-assisted minilaparotomic radical retropubic prostatectomy (EAM-RRP) compared with conventional radical retropubic prostatectomy (cRRP). METHODS: From September 2001 to December 2003, 30 patients with localized prostate cancer were treated by EAM-RRP. The surgical manipulation was performed through the wound with thoracoscopic assistance, using standard surgical instruments. In all cases, 800 mL of blood was collected from the patient for autotransfusion. For both EAM-RRP and cRRP, the internal iliac and obturator lymph nodes were dissected before the prostate removal. Clinical indicators such as operation time, blood loss, and duration of postoperative urine incontinence were analysed in the two groups. RESULTS: The postoperative period before ambulation and the duration of postoperative urine incontinence were significantly shorter after EAM-RRP than after cRRP, while no significant difference was found in operation time, blood loss, and duration of urethral catheterization. None of the cases required allotransfusion. CONCLUSION: EAM-RRP, which had a shorter postoperative period before ambulation and continence, is considered a safe and useful technique for radical prostatectomy.     

Effectiveness of prosthetic mandibular advancement for obstructive sleep apnea:Analysis by sleep position

Abstract Fifteen patients with obstructive sleep apnea were treated using prosthetic mandibular advancement (PMA). Each patient was evaluated in the supine and lateral decubitus positions with and without PMA. After PMA treatment, the mean intraesophageal pressure (Peso) in the supine position improved from -42.6 to -27.3 cmH₂O and the mean apnea + hypopnea index (AHI) decreased from 48.8/h to 23.7/h. The mean Peso in the lateral decubitus position improved from -27.9 to -18.6 cmH₂O and the mean AHI decreased from 9.6/h to 6.6/h. With PMA, respiratory disturbance during sleep further improved by changing the body position from the supine to lateral decubitus position.     

Megacystis and megacolon in an infant with Ehlers-Danlos syndrome

We report a 14 month old male infant with Ehlers-Danlos syndrome who became ‘anuric’ due to an acutely dilated urinary bladder. Although the patient was also found to have megacolon, no diverticulum was seen in his gastrointestinal tract or urinary bladder. In order to decompress the urinary bladder and colonic wall, we put an indwelling urinary catheter in place for 2 months, and carried out daily glycerin enema for 3 months. All urological and gastrointestinal symptoms subsided with this intensive medical treatment. The diagnosis of megacystis and megacolon was made very early in life for this patient. This may indicate that the striking extension of gastrointestinal and bladder wall may lead to the development of diverticula of gastrointestinal and urinary tracts in later life.     

A case of sub wakefulness syndrome

Abstract We report a patient, a 30-year-old male Japanese-Brazilian migrant construction worker, suffering from excessive daytime sleepiness for at least 6 months. Electroencephalogram recordings during his waking states showed that 10-Hz and 60-µV alpha activity was present prominently in the occipital regions. From the multiple sleep latency test, it was found that stages 1–2 NREM sleep episodes appeared repetitively without any REM episodes, and that the mean sleep latency was 10.2 min. These findings support the diagnosis that this patient suffers from subwakefulness syndrome.     

Varicella infection complicated with meningitis after immunization

A healthy 45 month old boy who had received varicella vaccine 21 months previously developed aseptic meningitis along with an episode of varicella. The presence of viral DNA in cerebrospinal fluid (CSF) detected by polymerase chain reaction (PCR) with Southern blot hybridization confirmed the relationship between the symptoms and the CSF pleocytosis. This is the first reported case of this complication of varicella meningitis occurring in a child with documented immunization and seroconversion.     

Inhaled nitric oxide and extracorporeal membrane oxygenation in persistent pulmonary hypertension of the newborn

Persistent pulmonary hypertension of the newborn (PPHN) may occasionally require an invasive treatment with extracorporeal membrane oxygenation (ECMO). Inhaled nitric oxide (NO) has recently been introduced as a selective pulmonary vasodilator for treatment of PPHN. We describe a case of PPHN in which neither inhaled NO nor ECMO was effective in reversing pulmonary hypertension. The clinical course of the patient suggested a potential role of NO inhalation in predicting the outcome of ECMO treatment for PPHN.
