  • Metastatic Disease The primary goal of treatment for metastatic disease is to achieve complete remission with chemotherapy alone or with a combined-modality approach of chemotherapy followed by surgical resection of residual disease, as is done routinely for the treatment of germ cell tumors. One can define a goal in terms of cure or palliation on the basis of the probability of achieving a complete response to chemotherapy using prognostic factors, such as Karnofsky Performance Status (KPS) (...

  • Bone morphogenetic protein (BMP) signals play key roles throughout embryology, from the earliest patterning events, via tissue specification, through organ development and again in germ cell differentiation. While both input and the transducer molecules are rather well studied, the final outcome of a BMP signal is basically unpredictable and differs enormously between previously studied cell types.

  • It is clear from the studies cited below, that good bedside manner and professionalism are extremely important to patients. Plunkett and Midland (2000) found that “well-educated” Caucasians (from Chicago, Michigan, US) placed an emphasis on communication skills when selecting an obstetrician. In contrast, patients who were to undergo surgery decided the surgical reputation of the OB/GYN was more important than bedside manner.

  • Harrison's Internal Medicine Chapter 92. Testicular Cancer Testicular Cancer: Introduction Primary germ cell tumors (GCTs) of the testis, arising by the malignant transformation of primordial germ cells, constitute 95% of all testicular neoplasms. Infrequently, GCTs arise from an extragonadal site, including the mediastinum, retroperitoneum, and, very rarely, the pineal gland. This disease is notable for the young age of the afflicted patients, the totipotent capacity for differentiation of the tumor cells, and its curability; about 95% of newly diagnosed patients are cured.

  • Malignant germ cell tumors are usually large (median—16 cm). Bilateral disease is rare except in dysgerminoma (10–15% bilaterality). Abdominal or pelvic pain in young women is the usual presenting symptom. Serum human chorionic gonadotropin (β-hCG) and α fetoprotein levels are useful in the diagnosis and management of these patients. Before the advent of chemotherapy, extensive surgery was routine, but it has now been replaced by careful evaluation of extent of spread, followed by resection of bulky disease and preservation of one ovary, the uterus, and the cervix, if feasible.

  • MicroRNAs are a class of small noncoding RNAs that function as key reg-ulators of gene expression at the post-transcriptional level. Recently, micr-oRNA-373 (miR-373) has been found to function as an oncogene in testicular germ cell tumors.

  • The chitosanase fromStreptomycessp. N174 (CsnN174) is an inverting glycoside hydrolase belonging to family 46. Previous studies identified Asp40 as the general base residue. Mutation of Asp40 into glycine revealed an unexpectedly high residual activity. D40G mutation did not affect the stereochemical mechanism of catalysis or the mode of interaction with sub-strate.

  • Encephalitis and Encephalomyelitis: Treatment Most types of paraneoplastic encephalitis and encephalomyelitis respond poorly to treatment. Stabilization of symptoms or partial neurologic improvement may occasionally occur, particularly if there is a satisfactory response of the tumor to treatment. The roles of plasma exchange, IVIg, and immunosuppression have not been established. Approximately 30% of patients with anti-Ma2-associated encephalitis respond to treatment of the tumor (usually a germ-cell neoplasm of the testis) and immunotherapy.
