Cyclophosphamide Therapy In A Serious Case Of Lupus Nephritis During Pregnancy., H Kart Köseoglu, A. Yücel, G. Künefeci, F. Ozdemir, E. Duran

Eyup Hakan Duran

Systemic lupus erythematosus (SLE) flare is common, and renal involvement is one of the most serious problems during pregnancy. Aggressive immunosuppressive therapy should be considered for patients with diffuse proliferative lupus nephritis. These individuals are at high risk for progression to end-stage renal disease. Immunosuppressive drugs can cause significant toxic and teratogenetic effects. In this report, we describe the case of a pregnant patient with lupus nephritis who was treated with cyclophosphamide. The patient was in the second trimester of her first pregnancy and did not respond to corticosteroid therapy. She underwent intensive in-hospital care while she was on cyclophosphamide …

Achievement Of Pregnancy In Globozoospermia With Y Chromosome Microdeletion After Icsi., Hulusi Zeyneloglu, Volkan Baltaci, E. Duran, Esra Erdemli, Sertac Batioglu

Eyup Hakan Duran

Pregnancy achieved with sperm from a patient with globozoospermia is rare, even after ICSI, since the activation of the oocyte may not occur in this disorder. Therefore, activation of the oocytes by piezoelectricity or calcium ionophores has been suggested, although spontaneous activation of the oocyte after ICSI has been reported in some cases. We report a successful pregnancy in a couple in which the male partner had globozoospermia with microdeletions in the Y chromosome with no further assisted activation after ICSI. During the diagnostic study of the husband, increased numerical chromosome abnormalities after fluorescent in-situ hybridization (FISH) and microdeletions in …

Endometrial Response To Unopposed Estrogens Remains Unaltered In Patients With Chronic Renal Failure Receiving Hemodialysis, M. Ergeneli, Eyup Duran, H. Zeyneloglu, B. Demirhan, M. Erdogan

Malignant Mixed Mesodermal Tumor Arising In A Benign Cystic Teratoma, M. Ergeneli, B. Demirhan, Eyup Duran, M. Coskun

Eyup Hakan Duran

The occurrence of sarcoma in a benign cystic teratoma is very rare. We report the first poorly differentiated, malignant mixed mesodermal tumor with a component of rhabdomyosarcoma to arise in a benign cystic teratoma of the ovary. The tumor was staged as FIGO IC due to capsule invasion. Although combination chemotherapy of cisplatin, ifosfamide and mesna, was instituted, the disease took a rapidly progressive course. After an unusual metastasis to the scapula was detected, the patient deteriorated and died in the forth postoperative month.

Extragenital Malignant Mixed Mesodermal Tumor: Case Report And Review Of The Literature, M. Ergeneli, B. Demirhan, Eyup Duran, M. Erdogan

Eyup Hakan Duran

Malignant mixed mesodermal tumors rarely occur in extragenital sites. An 80-year-old patient presented with a malignant mixed mesodermal tumor, consisting of papillary serous adenocarcinoma and chondrosarcomatous components. The patient refused further treatment following surgery and died of disease 2.5 months later. Based on the present case and a review of the literature, primary extragenital malignant mixed mesodermal tumors prove to be rare but highly malignant neoplasms. Further data is yet to be gathered in order to determine the exact origin and behavior of these tumors.
