Granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin instillation therapy

We report a rare case of granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin (BCG) instillation therapy in a 58-year-old man, which followed transurethral resection (TUR) for recurrent bladder cancer, when his anterior urethra was slightly narrow and his foreskin was with phimosis. Intravesical BCG instillation therapy was started for prophylaxis of recurrent bladder cancer after TUR. Multiple painless firm papules on glans penis, edema in the foreskin and low-grade fever appeared after the seventh instillation, for which the single antituberculous agent isoniazid (300 mg/day) was administered. Biopsy of the papules on glans penis and foreskin revealed granulomatous balanoposthitis. Low-grade fever normalized and the papules disappeared within 1 week. The patient continued chemotherapy with isoniazid for the next 12 months. There was no recurrence of bladder cancer or balanoposthitis for 15 months and to date.     

Humidification during high-frequency oscillation ventilation is affected by ventilator circuit and ventilatory setting

Background:  High-frequency oscillation ventilation (HFOV) is an accepted ventilatory mode for acute respiratory failure in neonates. As conventional mechanical ventilation, inspiratory gas humidification is essential. However, humidification during HFOV has not been clarified. In this bench study, we evaluated humidification during HFOV in the open circumstance of ICU. Our hypothesis is that humidification during HFOV is affected by circuit design and ventilatory settings.
Methods/Materials:  We connected a ventilator with HFOV mode to a neonatal lung model that was placed in an infant incubator set at 37°C. We set a heated humidifier (Fisher & Paykel) to obtain 37°C at the chamber outlet and 40°C at the distal temperature probe. We measured absolute humidity and temperature at the Y-piece using a rapid-response hygrometer. We evaluated two types of ventilator circuit: a circuit with inner heating wire and another with embedded heating element. In addition, we evaluated three lengths of the inspiratory limb, three stroke volumes, three frequencies, and three mean airway pressures.
Results:  The circuit with embedded heating element provided significantly higher absolute humidity and temperature than one with inner heating wire. As an extended tube lacking a heating wire was shorter, absolute humidity and temperature became higher. In the circuit with inner heating wire, absolute humidity and temperature increased as stroke volume increased.
Conclusion:  Humidification during HFOV is affected by circuit design and ventilatory settings.     

FIRES AND EXPLOSIONS WITH COMPRESSED GASES: Report of an Accident

A case of near-fire with resultant burns to an anaesthetistis reported. This happened upon opening the regulator valveof an oxygen cylinder which probably had been contaminated withliquid paraffin. Possible mechanisms of the accident is discussed.     

A challenge to chronic kidney disease in Asia: The report of the second Asian Forum of Chronic Kidney Disease Initiative

Background: The Asian Forum of Chronic Kidney Disease Initiative started in 2007 in Hamamatsu, Japan when delegates from 16 countries joined together to facilitate collaboration in studying chronic kidney disease (CKD) in the Asia–Pacific region. Based on the outcome of the first meeting, the second meeting was organized as a consensus conference to frame the most relevant issues, and develop research recommendations and action plan. Proceedings: The meeting was held on 4 May 2008 as a pre‐conference meeting to the 11th Asian Pacific Congress of Nephrology in Kuala Lumpur. This meeting consisted of three sessions: Session I was dedicated to the estimation of glomerular filtration rate and the standardization of serum creatinine measurements. Session II discussed specific considerations in the aetiology of and risk factors for end‐stage renal disease in Asia. We concluded that there were regional specific problems that might lead to a very high prevalence of end‐stage renal disease. Session III discussed the issue of facilitation of coordination and integration of the CKD initiative between developed and developing countries in the Asia–Pacific region. Conclusion: The following action plans were formulated: (i) validating the existing global estimated glomerular filtration rate equation or creating a new one using serum creatinine standardized by a central laboratory; (ii) establishing a pan‐Asian CKD registry to facilitate risk analysis of CKD and its comorbidities; (iii) adapting existing clinical practice guidelines for CKD detection and management to address specific problems in this region; and (iv) working closely with other international professional organizations to promote manpower development and education in different aspects of CKD in developing countries.     

Proliferative fasciitis of the forearm: Case report with immunohistochemical, ultrastructural and DNA ploidy studies and a review of the literature

A case of prollferative fasclitis arising In the left forearm of a 56-year-old man was examined. The lesion was preceded by blunt trauma, measured 1.5 times 1.3 times 1.0 cm, was poorly circumscribed and appeared white to light gray on the cut surface. Light microscopic examinations revealed that spindle cells and giant cells with one or two nuclei and abundant basophllic cytoplasm ware arranged without any organized patterns In collagenous stroma. Ultrastructurally, well-developed rough endoplasmic reticulum separated by varying amounts of fine to course fibrillar materials was detected in the giant cells. Only vimentin lmmunoreactivity was detected In both spindle and gtant cells. The Ki-67 labeling Index of spindle cells was 35% but that of giant cells was less than 5%, and this reflects the quiescent or slow-growing features of these giant cells in proliferative fasclitis. DNA content of the calls, which was examined by Image cytometry, demonstrated diploidy In both spindle (DNA Index = 1.01) and glant (DNA Index = 1.09) calls.
