Effects of blast injury on kidneys in abdominal gunshot wounds.

Objectives: To determine the rate of renal fragmentation resulting from blast effects and perform microscopic examination of renal arteries after gunshot wounds resulting from a high-velocity bullet.

Methods: A total of 194 patients with gunshot wounds due to blast effects underwent surgical exploration. Of the 194 patients, 35 (18%) had 37 renal unit injuries (2 patients had bilateral renal injury).

The role of lipoid proteinosis in gingival hypertrophy.

Hyalinosis cutis et mucosae (lipoid proteinosis, Urbach-Wiethe disease) is a rare syndrome with autosomal recessive inheritance. The disease is characterized by diffuse deposition of a hyalinelike substance in the dermis, submucosal connective tissue, and various internal organs. In this study, the patient demonstrated classic signs and symptoms of lipoid proteinosis except for gingival infiltration.

Acute pyelonephritis causing acute renal allograft dysfunction.

In renal transplant recipients, acute pyelonephritis may cause acute deterioration of renal function. We report a case with acute allograft failure due to acute pyelonephritis, which was confirmed by graft biopsy. After appropriate antimicrobial therapy, allograft function recovered.

Membranous glomerulonephritis, antiphospholipid syndrome, and persistent low C3 levels associated with meningococcal disease.

A young male patient with a recent history of meningococcemia was referred to our hospital in his recovery period. He had signs suggesting deep venous thrombosis in the legs but no other abnormalities on physical examination at admission. Laboratory results showed proteinuria (3.
