Treatment of Immature Teratoma Associated with Ovarian Endometrioma: A Case Report.

Background: Mature teratoma is a benign neoplasm, mostly composed of well-differentiated derivations of almost two or three germ cell layers, while immature teratoma is a malignant neoplasm composed of immature neural and embryonic tissue. Immature teratoma in the context of ovarian endometrioma has not been reported yet.

Case Presentation: A 34-year-old woman with primary infertility is reported in this study who suffered from immature teratoma associated with ovarian endometrioma.

The Importance of Evaluating Serum Levels of Tumor Markers M2-PK and Inhibin A in Patients Undergoing Colonoscopy.

Despite the use of colonoscopy to detect colon cancer due to its aggressiveness, high cost, and lack of patient compliance, the use of laboratory tests with high accuracy and sensitivity, such as tumor marker M2-PK and Inhibin A is recommended and can be effective for early diagnosis and screening of patients in the early stages. We studied 46 patients admitted it the gastrointestinal ward of Amir al Momenin Hospital and 45 normal (age and sex-matched) subjects as a control group (case-control and retrospective studies). Before the colonoscopy, the level of tumor marker M2-PK in the stool sample and the serum level of Inhibin A were evaluated in patients and the control group.

PEComa-A Rare Uterine Neoplasm: A Case Report.

Background: Perivascular Epithelioid Cell Tumors (PEComas) are rare mesenchymal tumors originating from perivascular epithelioid cells. The second common affected organ is uterine. Most of PEComas are benign and patients have good prognosis.

Rhabdomyosarcoma of the uterus in an adult patient with osteopetrosis: a case report.

Background: Uterine sarcoma accounts for 3-7% of uterine malignant neoplasms. It is more aggressive than epithelial neoplasms, and patients have a poor prognosis. Rhabdomyosarcoma is classified as a heterologous uterine sarcoma.

Relationship between Femoral Intercondylar Notch Narrowing in Radiography and Anatomical and Histopathologic Integrity of Anterior Cruciate Ligament in Patients Undergoing Total Knee Replacement Surgery.

Background: The presence of cruciate ligaments is very important for normal knee kinematics. Knee arthroplasty prostheses, in which these ligaments are maintained, have better kinematics. The aim of the present study was to investigate the association between femoral intercondylar notch (FIN) narrowing in radiography and clinical and histopathologic integrity of anterior cruciate ligament (ACL) in patients undergoing knee replacement surgery.

Effects of Nitroglycerine on Renal Ischemia-Reperfusion Injury in Adult Male Rats.

Background: Ischemia-reperfusion (I-R) leads to acute kidney injury (AKI). The present study investigated the effects of nitroglycerine (NG) on improving renal dysfunctions caused by I-R in rats.

Methodology: Twenty-four rats were equally divided into four groups: (1) the control group, (2) the sham group, (3) the I-R group, and (4) NG-treated groups.

Ameliorative Effects of Zataria Multiflora Hydro-Alcoholic extract on Gentamicin Induced Nephrotoxicity in Rats.

Background: Nephrotoxicity is the major side effects of aminoglycoside antibiotics such as gentamicin. The aim of this study was to investigate the therapeutic effects of Z.multiflora (ZM) hydroalcoholic extract on gentamicin-induced nephrotoxicity.

Effects of Cobalamin (Vitamin B12) on Gentamicin Induced Nephrotoxicity in Rat.

The main side effect of gentamicin is nephrotoxicity. The effect of cobalamin (Cob) was investigated on gentamicin nephrotoxicity in rats. Renal injury induced by i.

Intradural Intramedullary Teratoma Presenting in the Lumbar Spine: Report of a Rare Case.

Background: Intradural teratomas are an exceedingly unusual phenomenon. They are tumors with the cellular constituent source of all the 3 germ cell layers.

Case Description: We here report a case of an 18-year-old man with special pathologic features.

Does Histologic Subtype Influence the Post-Operative Outcome in Spinal Meningioma?

Background: Postoperative outcome of spinal meningiomas is an important issue in surgery decision-making. There are limited and conflicting data in the literature about the prognostic factors influencing recovery, especially about the histopathologic subtypes.

Objectives: This study was carried out to evaluate the effect of some of these factors on postoperative outcome.

Oxaliplatin-induced renal tubular vacuolization.

Objective: Chemotherapy with oxaliplatin is used for a wide range of malignancies. Unlike other platinum derivatives, oxaliplatin has less nephrotoxicity. However, in recent years, there have been multiple reports of different forms of renal toxicity related to this agent.

Methylation of O6-methyl guanine methyltransferase gene promoter in meningiomas--comparison between tumor grades I, II, and III.

Background: Meningiomas are the second most common primary intracranial tumors after gliomas. Epigenetic biomarkers such as DNA methylation, which is found in many tumors and is thus important in tumorigenesis can help diagnose meningiomas and predict response to adjuvant chemotherapy. We investigated aberrant O6- methyl guanine methyltransferase (MGMT) methylation in meningiomas.

Ruptured aneurysm of the splenic artery: a rare cause of abdominal pain after blunt trauma.

Introduction: Splenic artery aneurysms (SAAs) are rare (0.2-10.4%); however, they are the most common form of visceral artery aneurysms.

Simultaneous gastric adenocarcinoma and gastrointestinal stromal tumor of the stomach: a case report.

Simultaneous a collision tumor of stomach consisting of adenocarcinoma and Gastrointestinal Stromal Tumor (GIST) is very rare based on our knowledge. This coexistence has rarely been reported in literatures. We report a case of 64-year-old woman who has diagnosed with prepyloric poorly-differentiated diffuse signet-ring cell type adenocarcinoma and has undergone an elective D2 total gastrectomy.
