PURPOSE: To determine the types of meniscal tears and type of popliteal muscle attachment in lateral disccid menisci. MATERIALS AND METHODS: MR images from 40 patients with arthroscopically proven disccid meniscal tears were reviewed. The type of capsular attachment of the popliteal muscle in these patients was compared with 100 normal controls. Fourteen men and 26 women were included in this study ranging in age from 8 to 52 yea rs. RESULTS: Disccid mensical tears were divided into five types. Arthroscopic cor- relation revealed that thirty-six cases(90%) of disccid meniscal tears were cor- rectly diagnosed using MR imaging. Peripheral tear wasthe commonest tear type occurring in 13 patients. In 9 of these the meniscal fragment was displaced. Hori- zontal tears occurred in 5, longitudinal tears in 4 and transverse tears in 2 patients. Multiple tears were present in 16 patients with the commonest combi- nation of peripheral and horizontal. Popliteal capsular attachments of disccid mensical tears were more prominent than in the normal control group. CONCLUSION: The types of tears in disccid menisci were different from normal meniscal tears. Peripheral detachment with displacement of torn segments was a very frequent finding in disccid mensical tears. Prominent capsular attachment of popliteal muscles is probably an associated finding in disccid menisci.

PURPOSE: To characterize MR findings of meniscal cysts of the knee. MATERIALS AND METHODS: We retrospectively reviewed knee MR images of surgically confirmed eighteen meniscal cysts. The location and shape of meniscal cysts were evaluated. RESULTS: Six of 18 cases were medial meniscal cysts and 12 of 18 cases were lateral meniscal cysts. Horizontal tears were present in all cases(100%). Four of 18 cases had rounded cysts and 14 of 18 cases had elongated cysts. In 3 of 6 medial meniscal cysts, cysts had dissected into the soft tissues distant from the meniscus, and connecting stalks were visualized. Three of 6 medial meniscal cysts were located adjacent to a meniscal tear. All of the lateral meniscal cysts occurred immediately adjacent to the meniscal tear. CONCLUSION: Meniscal cysts are associated with horizontal meniscal tear. The shapes of meniscal cysts tend to be elongated rather than rounded. Medial meniscal cysts occurred distant from or adjacent to the meniscal tear according to location of the tear. Lateral meniscal cysts occurred adjacent to the meniscal tear.

Herpes simplex esophagitis has been recognized with increased frequency as an opportunistic infection in immunosuppressed or debilitated patients. However, it is also documented as self-limited esophagitis in apparently healthy patients. We report two cases of herpetic esophagitis diagnosed by biopsies. One case was noted in an immunocompetent patient having gastric peptic ulcer who had clinical improvement with symptomatic treatment. And the other was noted in an immunosuppressed patient having chemotherapy for gastric carcinoma who had resolution of symptoms with acyclovir therapy. Histologically, esophageal mucosa exhibited erosion and inflammatory cellular exudate with intranuclear eosinophilic inclusions in the epithelial cells. These were confirmed by the PCR and immunohistochemical stain for herpes simplex virus using a biopsy material.

A 23-year-old man had multiple small, skin-colored firm papules on the both sides of the nasolabial folds since the age of approximately 17. His mother had a similar skin lesions on her face. The histopathological findings of skin biopsy specimens from patient(son) showed horn cysts consist of a fully keratinized center surrounded by basophilic cells and tumor islands composed of basophilic cells arranged in a lacelike or adenoid network and occasional solid aggregates and there are also a foreign body giant cell reaction in the vicinity of the ruptured horn cysts.

Pulmonary comp1ications following surgery continue to be a major cruse of postoperative mobidity. The purpose of this study was to measure the effects of various surgical procedures upon arterial blood gas tension and ventilatory function in the early postoperative period. 30 patients with no history of cardiopulmonary disease before surgery were selectively chosen and divided into 4 categories depending on the location of the operative incision and the type of anesthesia. Group l was composed of upper abdominal incision cases, Group ll lower abdominal incision cases, and Groups lll and lV had nonabdominal surgery. Groups, l, ll and lll received general anesthesia, while lV was liven spinal anesthesia. Lung volumes were measured and blood samples were taken preoperatively and 70 minutes after surgery. Patients were maintained in semisitting position before and after surgery. Vital capacities were significantly reduced in the postoperative period in the general ane- sthesia groups, and tidal volumes were significantly reduced in the upper and lower abdominal incision groups. The mean PaO2 value after anesthesia decreased significantly in the upper and lower abdominal incision groups, but there were no significant differencea in the PaCO2 value. It seems that supplemental oxygen and encouragement of deep inspirations are essential and beneficial in the early postoperative period, especially for the patients with abdominal surgery.

We present a case of mycosis fungoides of an 52-year-old woman who showed multiple pruritic erythematous papules, plaques with ulcers on the trunk, extremities and face. Her skin biopsy specimens were studied irnmunohistochemically with, monoclonal antibodies against T cells(80%, Leu-4, OKT11), T-cell subsets (60% Leu-3a, OKT4a, 40% OKT8) and Langerhans cell(OKT6). We think that this case should be considered in the differential diagnosis of adult T-cell leukemia/lymphoma. The proliferating cells were negative for anti-Tac.
