    Notes: Abstract Laryngeal atresia (LA) is an uncommon congenital anomaly, and only a few cases with long-term survival are reported in the literature. The authors describe a 2-year-old boy with LA and esophageal (EA), intestinal, and urethral atresia (UA). Immediately after birth, severe respiratory distress and mild abdominal distension became evident. Endotracheal intubation was unsuccessful and emergency tracheal puncture was performed, after which a tracheostomy was constructed. Direct laryngoscopy revealed LA at the vocal cord level. A cystostomy and gastrostomy were constructed immediately because of UA and EA. A cystocutaneostomy, ileocolic anastomosis, and resection of a tracheoesophageal fistula (TEF) were simultaneously performed 1 day after birth. The EA was proximal with a distal TEF. The gap between the ends of the upper and lower esophagus was 4 cm in length. It was thought impossible to perform a primary anastomosis, and therefore, a gastrostomy and resection of the TEF using multiple-stage surgery was undertaken. Intestinal resection and anastomosis were performed due to intestinal stenosis from necrotizing enterocolitis at the age of 3 months. Hypoxic encephalopathy developed due to accidental obstruction of the tracheostomy tube at the age of 10 months, and physical therapy was begun. He required a cutaneous nephrostomy due to a right hydromegaureter with vesicoureteric reflux and a left non-functioning kidney at the age of 23 months. He has been hospitalized for partial ventilatory assistance for 2 years at our institution. The course of this patient seems noteworthy in relation to the genesis of the multiple malformations.

    Notes: Abstract The expression of human placental-type glutathione S-transferase (GST-π) was investigated in human cutaneous squamous cell carcinoma (SCC) and normal skin using Northern blot and immunohistochemical analysis. In Northern blot examination, the expression of GST-π transcript was recognized in all instances, and SCC showed a significantly higher expression of GST-π than normal skin. In immunohistochemical examination, GST-π was stained well in the cytoplasm of all cells of the stratum granulosum, many cells of the stratum spinosum and a few cells of the stratum basale in normal skin. Some cells of the stratum spinosum and almost all cells of the stratum basale showed only a weakly positive or almost negative reaction for GST-π. No nuclear staining of GST-π was obvious in normal epidermal cells. In SCC, many cells showed strong positivity for GST-π in the cytoplasm, and some were obviously accompanied by nuclear staining of GST-π. These findings suggest that GST-π exists mainly in many cells in the upper layers of the normal epidermis and that GST-π is involved in the process of carcinogenesis.
