Congenital cytomegalovirus (CMV) infection can cause severe permanent disabilities. A mother who is seronegative before conception but acquires infection during pregnancy is a risk factor for congenital infection. We describe a neonate in whom congenital CMV infection was diagnosed at birth and confirmed with DNA quantitation by means of the polymerase chain reaction, was accompanied by cerebral ventriculomegaly and severe hearing loss, and was treated with ganciclovir/valganciclovir for 6 weeks. ⋯ Single-photon emission computed tomography showed marked improvement 6 months after treatment. This case provides compelling evidence that a reliable diagnosis of congenital CMV infections coupled with a prompt and appropriate treatment program can prevent permanent disability. It is, therefore, important to establish a more effective strategy for the management of congenital CMV infection.

Like other forms of laparoscopic surgery, laparoscopic pancreaticoduodenectomy (Lap-PD) is a minimally invasive procedure that can greatly reduce bleeding during surgery. We performed Lap-PD for a case of intraductal papillary mucinous neoplasm. To remove the resected tissue from the body, we made a small incision directly above the line of transection of the distal pancreas (the cut stump). ⋯ All reconstructive procedures, except for hepaticojejunostomy, were performed under direct visualization; hepaticojejunostomy was performed laparoscopically. The reconstructive surgery was effective and was as safe as open abdominal surgery. We also discuss the value of using an endoscopic linear stapler for Lap-PD pancreatic transection, to reduce extravasation of pancreatic fluid into the abdominal cavity during the resection of tumors involving the pancreatic ducts, such as intraductal papillary mucinous neoplasm.

Cervical anterior fusion with the Williams-Isu method: clinical review.
Anterior decompression and fusion of the cervical spine is a widely accepted treatment for cervical canal disease. The Williams-Isu method involves cervical anterior fusion with autologous bone grafts from cervical vertebral bodies. Its advantages are a wide operative field, excellent graft fusion, the absence of problems related to the iliac donor site, and direct visualization of the nerve root. ⋯ To reduce the levels to be fused in patients with multilevel lesions due to cervical disease, the Williams-Isu method can be combined with the transvertebral approach. The transvertebral approach facilitated by the wide Williams-Isu window allows the root bifurcation area to be confirmed during the early stage of surgery and possible decompression along the root. Radiological examination has shown that the combination of the Williams-Isu method and transvertebral approach does not affect the fusion level compared with the Williams-Isu method alone and produces better results than does the transvertebral approach alone.

The fundamental principles of survival analysis are reviewed. In particular, the Kaplan-Meier method and a proportional hazard model are discussed. This work is the last part of a series in which medical statistics are surveyed.

Randomized Controlled Trial
Objective assessment of postoperative gastrointestinal motility in elective colonic resection using a radiopaque marker provides an evidence for the abandonment of preoperative mechanical bowel preparation.
It has been suggested that mechanical bowel preparation (MBP) has no benefit in terms of anastomotic healing, infection rate, or improvement in the postoperative course in patients undergoing elective colorectal surgery, and that it should be abandoned. However, the effect of MBP on postoperative gastrointestinal motility has been assessed subjectively. In this randomized trial, we objectively assessed the effect of MBP on postoperative gastrointestinal motility and mobility in elective colonic resection. ⋯ Our data provide additional evidence to support the abandonment of MBP in elective open colonic surgery.
