Pigmented neurofibroma, a variant of neurofibroma, has rarely been observed in patients with or without neurofibromatosis. Pigmented neurofibroma is characterized histologically by the coexistence of scattered melanin-laden cells and benign spindle cells with neural differentiation. We report a case of pigmented neurofibroma in a 22-year-old female patient.

Eight bacterial strains were examined whether they have phoP/phoQ genes which were known to be involved in the intracellular survival of Salmonella typhimurium. The phoP/phoQ operon were known to sense the stimuli of the genes involved in the adaptation of the environment. Using 514-basepairs EcoRV DNA fragment of phoP region of Salmonella typhimurium as a probe, dot blot hybridization were performed. Chromosomal DNAs of Klebsiella pneumonia, Pseudomonas aeruginosa, Serratia marscescens, Enterobacter cloacae, Salmonella typhimurium, Escherichia coli, Shigella dysenteriae, and Listeria monocytogenes were examined by DNA hybridization assay. Against our expectation, intracellular pathogen, L. monocytogenes, did not have similar DNA sequences to phoP/phoQ of S. typhimurium, while E, coli, S. dysenteriae, and E. cloacae showed the positive signal even though they were not intracellular pathogens. This result suggested that the phoP/phoQ operon was absent in intracellular pathogenic bacterias other than S. typhimurium. Rather it was found in phylogenetically closer bacterias to S. typhimurium, which were not able to survive in intracellular environment. Some different mechanism, which is not dependent on phoP/phoQ operon, could be involved in the intracellular survival of L. monocytogenes.

Allopurinol is a xanthine oxidase inhibitor widely used to control plasma uric acid levels. Serious and life threatening adverse effects such as the allopurinol hypersensitivity syndrome(AHS) are rare. We describe a 32-year-old female patient who was treated with allopurinol and developed fever, rash, and renal and liver dysfunction.

ACL plays an important role in stability of knee joint and its injury causes instability of joint which is known as the initiation of problem knee. Reconstruction of the anterior cruciate ligament would be preferred to the primary repair in treatment. And recently with the advance of arthroscopic technique and development of bone-patellar tendon-bone (BPB) graft material, the result of reconstruction is somewhat superior to that of primary repair. Authors compared the results of 20 primary repairs (Group I ) and 20 reconstructions (Group II) among 64 acute ACL injury treated Sung-Ae General Hospital from January 1989 to December 1994. The results were as follows: 1. Most common associated injuries were medial collateral ligament rupture and medial meniscal tear. 2. Group I showed postoperatively 13 negative anterior drawer test, 12 negative Lachmann test and 12 negative pivot shift test and group II showed postoperatively 17 negative anterior drawer test, 15 negative Lachmann test and 17 negative pivot shift test. (p<0.05) 3. In postoperative Lysholm knee scoring scale, group I showed 86 points and group II showed 93 points (p<0.05). 4. In postoperative KT-1000 arthrometer, 12 cases in Group I and 16 cases in Group II showed less than 2mm difference with sound side (p<0.05).

The fat embolism syndrome is a complication which encounters rarely after fractures of pelvis and long bones of lower extremity of severe injury of soft tissue, and may results in microinfarctions in lungs, brain, heart, kidneys and other important organs when fat globules flow from bone marrow into small vessels. And that is the one of the main cause of death within 72 hours after major trauma of long bones. Diagnosis of fat embolism syndrome was made by clinical criteria by Gurd, but, majority of cases didn't show characteristic clinical symptoms or signs. Recently CT and MRI of the brain are adopted to the diagnosis of FFS as a new method. Authors experiences six cases of fat embolism syndrome from Mar. 1991 to Mar. 1994 and analyzed the brain MRI findings. We concluded that the brain MRI findings such as diffuse brain swelling, petechial hemorrhage and microinfarctions were helpful to diagnose clinically apparent or subclinical fat embolism syndrome.

Acroangiodermatitis is a reactive vasoproliferative disorder of cutaneous blood vessels. It usually has underlying conditions of increased venous pressure or circulatory abnormality. We report a case of acroangiodermatitis associated with arteriovenous fistula. A 52-year-old man was referred to our department because of purplish brown colored crusted plaques on his left third, fourth, and fifth fingers. He was chronic renal failure patient who had received hemodialysis by arteriovenous fistula on his left forearm for 2 years. Histopathologically, a biopsy revealed proliferation of capillaries and extravasated erythrocytes in the dermis.
