PURPOSE: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. MATERIALS AND METHODS: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's(R) Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS(R) proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. RESULTS: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. CONCLUSION: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.

This study was undertaken to observe the effects of centrally administred antihistamines on the blood pressure. Diphenhydramine(DPH), a H1-receptor antagonist, and ranitidine(RAN), a H2-receptor antagonist were administered intracerebroventricularly(icv) on urethane-anesthetized rabbits. 1) Both DPH and RAN administered intraccebroventricularly increased blood pressure, however the intravenous(iv) adminstration of them did not affect blood pressure. The pressor response to icv DPH was dose-dependent, but that to icv RAN was not. 2) The pressor response to icv DPH(1mg) was either markedly attenuated or reversed to depressor response by the pretreatment with icv phentolamine(250,500ug), and iv chlorisondamine(0.1, 1mg/Kg) and iv phenoxybenzamine(1mg/Kg). In cord-sectioned rabbtis, icv RAN) 1mg) did not produce pressor response. 3) The pressor responsr to icv RAN(1mg) was not affected by the pretreatment with icv phentolamine(500ug), iv chlorisondamin(1mg/Kg) and iv phenoxybenzamine(1mg/Kg), and iv phenoxybenzamine(1mg/Kg). RAN also producted pressor response in cordsectioned rabbits. These results suggest that the pressor response to icv DPH is elecited by increasing peripheral sympathetic tone via the stimulation of central alpha-adrenoreceptors and the pressor response to icv RAN is produced by releasing some humoral facotr which can increase blood pressure.

Fibrohistiocytic tumors are a diverse group of benign and malignant soft tissue lesions, including dermatofibroma, dermatofibrosarcomaprotuberans, and malignant fibrous histiocytoma. On the clinical point of view, the distinction between benign and malignant lesions and malignancy grading is far more important. Therefore, we investigated 23 fibrohistiocytic tumors, using PCNA (PC10) which was a useful marker of proliferating activity, to differentiate the benign lesions from the malignant and correlate with other prognostic factors including tumor necrosis. cellularity, histologic grade, and mitotic counts. The results obtained were as follows 1) Positive tumor cells were clearly identified by the characteristic diffuse or granular nuclear staining. 2) The number of PCNA-positive tumor cells were 2.16+/-2.39% in dermatofibroma, 16.12+/-7.38% in dermatofibrosacoma protuberans, and 28.02+/-17.47% in the malignant fibrous histiocytoma. The numbers of PCNA-positive tumor cells in the malignant lesions higher than in the benign (p<0.001). 3) Deep seated, large size (>5 cm) and recurred or metastatic cases of MFH were more the high PCNA index (more than 20%) than the low index (less than 20%) groups. 4) PCNA index in MFHs had positive correlation with the number of mitotic counts (r=0.7582, p<0.001), cellularity (r=0.5908, p<0.05) and histologic grade (r=0.4164, p<0.05). These results suggested that reactivity on PCNA might assist in the distinction between benign and malignant lesions in fibrohistiocytic tumors, and could be a useful prognostic factor in the patients with malignant fibrous histiocytoma.

The incidence of cervical pregnancy and the number of combined intrauterine pregnancy and ectopic pregnancy seems to be increasing. So the possibility of heterotopic pregnancy should always be considered by every gynecologist, especially those who treat infertility problem. We experience a case of a heterotopic pregnancy coexisting of an intrauterine pregnancy and a cervical pregnancy after in-vitro fertilization and embryo transfer, and was successfully managed by transcervical evacuation and resulted in a normal intrauterine pregnancy. Here we present the case with review of literatures.

A complete hydatidiform mole coexisting with a fetus is a rare condition, particularly when diagnosed after IVF-ET. In spite of the wide spread use of assisted reproductive technology, there have been, to our knowledge, only few reported cases of molar pregnancy after IVF-ET. At present, there are limited data to guide the antenatal management of a complete hydatidiform mole coexisting with fetuses. A complete mole can coexist with a normal, healthy fetus who can be carried to term, with good outcome. But, patients who desire to continue the pregnancy after such a diagnosis must be cautioned about the potential for severe medical complications and developing persistent gestational trophoblastic tumor. We report here a case of complete hydatidiform mole in a triplet pregnancy coexistent with two live fetuses following in IVF-ET.

Laparotomy performed for resection of hepatoma in 34 cases at Seoul National University Hospital for 3 .5years since Oct. 1978. Resection of hepatoma was done in 21 cases, ligation with or without canulation of hepaticartery was performed in 12 cases, and open and closure was made in 1 case. Angiographic findins were analyzed forresectability of hepatoma. The results of hte analysis were as follows; 1. Most reliable signs for resectablehepatoma were peripheral location and confinement in one hepatic lobe. Most reliable signs for non-resectablehepatoma were presence of tumor thrombus in portal vein, bilateral hepatic arterial feeding. 2. Less reliablesigns for resectable hepatoma were absence of portal vein invasion, less than 10cm in size and absence of findingsof liver cirrhosis. Less reliable signs for non-resectable hepatoma were right or left massive type. 3. Presenceof arteriovenous fistula, more than 10cm in size, and presence of findings of liver cirrhosis were no reliablecriteria for resectability of hepatoma. 4. Predictability for resectability with those reliable signs ofangiography was around 80%. 5. In addition to routine celiac angiography, oblique celiac angiography or superiormesenteric arteriography for portal vein opacification will be helpful in order to obtaine highly reliable signsfor resectability of hepatoma.

PURPOSE: This study was designed to validate the functional evaluation system after surgery of malignant musculoskeletal tumors by ISOLS (International Symposium On Limb Salvage). MATERIALS AND METHODS: The reliability, content and criterion validities of the ISOLS system were investigated using the Nottingham Health Profile, the Medical Outcome Study 36-item Short-Form Health survey and the EuroQol instrument to measure the quality of life of patients with malignant musculoskeletal tumors. Forty nine patients were evaluated Osteosarcoma around knee joint was most commonly. Prosthetic reconstruction was performed in 55.1%. RESULTS: In content validity analysis, no social and psychological domains was found in ISOLS and the domains for functions of the lower extremities had a strong Cronbach's coefficient (0.88). ISOLS exhibited strong correlation in criterion validity. Convergent validity was good but the discriminative validity was poor. ISOLS has reliability with a strong correlation with other golden standard outcome measures. CONCLUSION: Overall reliability and validity of the ISOLS system appeared to be acceptable. However, this system may need further development of its appropriate domains to evaluate the quality of life in patients with malignant musculoskeletal tumors.

PURPOSE: To evaluate the efficacy of in vitroretrieval of epididymal sperm for the induction of pregnancy in patients with post-testicular causes of infertility, and assess the sperm distribution within the epididymis of these patients. MATERIALS AND METHODS: Analyses of the sperm count and motility of sperm retrieved from the detached epididymis, and of the resulting fertilization and pregnancy outcomes were conducted. A total 62 infertile couples, due to post-testicular male causes, had sperm retrieved from the epididymis. The sperm count and motility, as well as the fertilization and pregnancy rates, were measured. RESULTS: Epididymal sperm was retrieved from 60 males with post-testicular infertility. The average sperm concentration and motility of the sperm after sperm preparation were 43.0x10(6)/ml and 25%, respectively. The clinical pregnancy rate per cycle was 57.9%(11/19) with in vitro fertilization(IVF), 39.0%(16/41) with intracytoplasmic sperm injection(ICSI) using fresh epididymal sperm, and 42.9%(27/63) with ICSI using frozen epididymal sperm. CONCLUSIONS: The in vitro retrieval of epididymal sperm is recommended as a simple and effective method to obtain viable sperm from infertile patients with obstructive azoospermia or sperm excretion disorders.
