We retrospectively reviewed clinical and radiologic findings of 19 patients who had been diagnosed as epithelial tumors of the lacrimal gland histopathologically after biopsy and surgery at Shinchon Severance Hospital from April, 1991 to July, 1998 and evaluated their correlation to the pathologic diagnosis, treatment and prognosis. There were 7 men and 12 women with the mean age of 41.0+/-13.3 years. Histopathologically, there were 7 cases of adenoid cystic carcinoma, 1 case of adenocarcinoma, 1 case of malignant mixed tumor, 9 cases of pleomorphic adenoma, and 1 case of benign oncocytoma. In comparison with benign epithelial tumor of the lacrimal gland, the characteristic clinical findings of malignant epithelial tumor of the lacrimal gland were pain, limitation of motion, and diplopia[44.4%]. The mean duration of the symptoms of malignant epithelial tumor was shorter[10.3+/-6.6 months] than that of benign epithelial tumor[19.5+/-14.4 months]. In radiologic CT and MRI findings, there were characteristic bony destructions in malignant epithelial tumors of the lacrimal gland[55.6%] compared with benign tumors and poorly marginated outline of the tumor was noted in malignant tumors[44.4%] but not in benign tumors. Therefore, clinical and radiologic findings of epithelial tumors of the lacrimal gland were well correlated with the pathologic diagnosis and would attribute to early diagnosis of malignant tumors.

Transfusion requirement or hemoglobin level has been a major indicator of the erythropoiesis of CRF patients. However, the more objective and earlier detectable parameters to monitor the erythropoiesis has been required. We investigated the significance of immature reticulocyte count(IRC) with flowcytometry in CRF patients as a convenient index of erythropoietin(EPO) therapy. We evaluated CRF patients undergoing hemodialysis(n=35) and normal control group(n=14). The 26 patients of CRF have been under EPO therapy, the others(n=9) have not been under therapy. 1) The response of IRC to EPO therapy : IRC increased daily 4.95% in average upto 3rd day and decreased daily 3.7% in average since then. 2) The similar IRC was maintained in similar hemoglobin state : IRC, total reticulocyte count(TRC) and hemoglobin were compared between CRF patients with low dose EPO therapy and those who weren't needed EPO administration from the beginning. 3) The increase of IRC depends on the dose of EPO : 4) Correlation between IRC and other hematologic parameters : IRC was significantly correlated with TRC and serum iron level(R value : 0.736, 0.522 respectively). Taken together, these results suggest that maintenance of IRC level, 8-10%, was necessary at a minimum to obtain 8g/dL of hemoglobin level. However, IRC level could be readjusted more than 20% with higher EPO therapy to maintain 8g/dL of hemoglobin in severe case. In conclusion, the measurement of IRC in CRF is clinically more objective, useful, earlier indicator for estimating erythropoiesis than hemoglobin and TRC.

The incidence of acute leukemia in pregnancy is rare. The treatment of acute leukemia during pregnancy is complicated and therapeutic options must be made with each individual patient. Complete remission can now be achieved in 60 to 70% of previously untreated adults with acute myelogenous leukemia (AML). Antileukemic chemotherapy can be administered safely during the second and third trimesters. Cytarabine (ara-C) and anthracycline has not been associated with birth defect. When a pregnant woman presents with acute leukemia, chemotherapy should be recommended as vigorously as in the non- pregnant woman. We reported a case of AML during pregnancy. The patient recieved induction chemotherapy with ara-C and idarubicin. The baby was delivered at 33 weeks of gestation and had transient neutropenia. The mother received consolidation chemotherapy after achievement of complete remission.

There is a greater incidence of discoid meniscus in Asian countries than in Western countries, and bilateral discoid menisci are also common. The discoid meniscus may be a congenital anomaly, and genetics or family history may play a role in the development of discoid menisci. Because the histology of discoid meniscus is different from that of normal meniscus, it is prone to tearing. Individuals with a discoid meniscus can be asymptomatic or symptomatic. Asymptomatic discoid menisci do not require treatment. However, operative treatment is necessary if there are symptoms. Total meniscectomy leads to an increased risk of osteoarthritis. Therefore, total meniscectomy is generally reserved for rare unsalvageable cases. Partial meniscectomy (saucerization) with preservation of a stable peripheral rim combined with or without peripheral repair is effective, and good short-, mid-, and long-term clinical results have been reported.

Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. When it is applied to tissues, catalase causes its rapid molecular degeneration with the release of oxygen bubbles. We present case report illustrating two hazards ; chemical colitis and oxygen embolus. A 29-year-old previously healthy woman presented to the bloody diarrhea and anal pain after hydrogen peroxide enema. In the colonoscopic examination, severe mucosal edema and ulceration with bleeding was noted from anus to sigmoid colon. With use of anal endosonography, multiple high level echo were noted in the internal and external anal sphincter of the upper anal canal. Microscopically, mononuclear cells were infiltrated in lamina propria and congestion. She had treatment with IV fluid, IV antibiotics and NPO. At 3rd hospital day, anal pain was disappeared. Bloody stool was disappeared next day. At 8th hospital day, mucosal edema and ulceration were disappeared on colonoscopic examination. Recovery was full and the patient was discharged at nine days after the episode.

BACKGROUND: The aims of our study were to evaluate the success rate of irrigation and debridement with component retention (IDCR) for acutely infected total knee arthroplasty (TKA) (< 4 weeks of symptom duration) and to analyze the factors affecting prognosis of IDCR. METHODS: We retrospectively reviewed 28 knees treated by IDCR for acutely infected TKA from 2003 to 2012. We evaluated the success rate of IDCR. All variables were compared between the success and failure groups. Multivariable logistic regression analysis was also used to examine the relative contribution of these parameters to the success of IDCR. RESULTS: Seventeen knees (60.7%) were successfully treated. Between the success and failure groups, there were significant differences in the time from primary TKA to IDCR (p = 0.021), the preoperative erythrocyte sedimentation rate (ESR; p = 0.021), microorganism (p = 0.006), and polyethylene liner exchange (p = 0.017). Multivariable logistic regression analysis of parameters affecting the success of IDCR demonstrated that preoperative ESR (odds ratio [OR], 1.02; p = 0.041), microorganism (OR, 12.4; p = 0.006), and polyethylene liner exchange (OR, 0.07; p = 0.021) were significant parameters. CONCLUSIONS: The results show that 60.7% of the cases were successfully treated by IDCR for acutely infected TKA. The preoperative ESR, microorganism, and polyethylene liner exchange were factors that affected the success of IDCR in acutely infected TKA.

The most common site for the metastasis of osteosarcoma is the lung, and other sites of metastases include the bone, lymph node, pleura and liver. Although unusual extrapulmonary metastases have been reported with the improvement of the therapeutic results for the primary lesions, they are exceptionally rare. We report here on a case of prostatic metastasis of an osteosarcoma of the proximal tibia, and this developed seven years after successful resection, and four years after resection of a pulmonary metastasis. Radical prostatectomy was performed, and histological examination demonstrated metastatic osteosarcoma. To the best of our knowledge, this is the first case of prostatic metastasis of osteosarcoma in the medical literature.
