Rhumatic fever has almost been eraicated in the developed world, however it remains prevelent in many under developed countries and causes devastating damage to heart valves. Up till recently valve replacement was the treatment of choice. The long term results and sequelae of valve replacement are...

common knowledge. Mitral and tricuspid valve replacement results are on the whole far worse than for example Aortic valve. Mitral valve replacement should be the last resort and patients with very severe valvular and sub valvular mitral disease can nowadays be helped by mitral valve repair. NO MITRAL OR TRICUSPID VALVE SHOULD BE REPLACED IF IT CAN BE REPAIRED

Urogenital neoplasms spreading to the inguinal lymph nodes are penile carcinoma (the most frequent), urethral and scrotum cancers, tumors of the testis with scrotal violation. Penile carcinoma is an uncommon malignant disease and accounts for as many 0.4-0.6% of male cancers. Most patients are elder...ly. It rarely occurs in men under age 60 and its incidence increases progressively until it reaches a peak in the eighth decade 1. The risk of a lymph node invasion is greater with high grade and high stage tumors 2. Some investigators have reported the inaccuracy of the sentinel node biopsy 3, 4, described by Cabanas 5. Patients with metastatic lymph node penis cancer have a very poor prognosis if penectomy only is performed. Ilioinguinal lymphadenectomy is basically carried out as a treatment modality and not only as a staging act. Patients with lymph node invasion have a 30-40% cure rate. Ilioinguinal lymphadenectomy should be also performed in patients with disseminated neoplasms for the local control of the disease. The 5 years survival rate of patients with clinically negative lymph nodes treated with a modified inguinal lymphadenectomy is 88% versus 38% in patients not initially treated with lymphadenectomy 6. This video-tape clearly shows a therapeutic algorithm, the anatomy of the inguinal lymph nodes, according to Rouviere 7 and Daseler 8, the radical ilioinguinal node dissection with transposition of the sartorius muscle and the modified inguinal lymphadenectomy proposed by Catalona 9.

Meniscus allograft survival in patients with moderate to severe unicompartmental arthritis: a 2- to 7-year follow-up.PURPOSE: We present meniscus allograft survival data at least 2 years from surgery for 45 patients (47 allografts) with significant arthrosis to determine if the meniscus can survive ...in an arthritic joint. Type of Study: Prospective, longitudinal survival study. METHODS: Data were collected for 31 men and 14 women, mean age 48 years (range, 14 to 69 years), with preoperative evidence of significant arthrosis and an Outerbridge classification greater than II. Failure is established by previous studies as allograft removal. No patient was lost to follow-up. RESULTS: The success rate was 42 of 47 allografts (89.4%) with a mean failure time of 4.4 years as assessed by Kaplan-Meier survival analysis. Statistical power is greater than 0.9, with alpha = 0.05 and N = 47. There was significant mean improvement in preoperative versus postoperative self-reported measures of pain, activity, and functioning, with P = .001, P = .004, and P = .001, respectively, as assessed by a Wilcoxon rank-sum test with P = .05. CONCLUSIONS: Meniscus allografts can survive in a joint with arthrosis, challenging the contraindications of age and arthrosis severity. These results compare favorably with those in previous reports of meniscus allograft survival in patients without arthrosis. LEVEL OF EVIDENCE: Level IV.
