Pelvic lymph node dissection for penile carcinoma: extent of inguinal lymph node involvement as an indicator for pelvic lymph node involvement and survival

PURPOSE: We identified pathological parameters of inguinal lymph node involvement with the aim of predicting pelvic lymph node involvement and survival. MATERIALS AND METHODS: A total of 308 patients with penile carcinoma and adequate followup were included in this study. The outcome of 102 patients who underwent lymphadenectomy for lymph node metastases was analyzed further. Histopathological characteristics of the regional lymph nodes were reviewed including unilateral or bilateral involvement, the number of involved nodes, pathological tumor grade of the involved nodes, and the presence of extracapsular growth. RESULTS: Tumor grade of the involved inguinal lymph nodes (OR 6.0, 95% CI 1.2-30.3) and the number of involved nodes (2 or less vs more than 2) (OR 12.1, 95% CI 3.0-48.1) were independent prognostic factors for pelvic lymph node involvement. Extracapsular growth (OR 2.3, 95% CI 1.1-4.8), bilateral inguinal involvement OR 3.4, 95% CI 1.2-9.4) and pelvic lymph node involvement (OR 3.1, 95% CI 1.4-6.6) were independent prognostic factors for disease specific survival. CONCLUSIONS: Patients with only 1 or 2 inguinal lymph nodes involved without extracapsular growth and no poorly differentiated tumor within these nodes are at low risk of pelvic lymph node involvement and have a good prognosis with a 5-year survival rate of approximately 90%. Pelvic lymph node dissection seems to be unnecessary in these cases.     

Unstable recent intracapsular femoral neck fractures in young adults: Osteosynthesis and primary valgus osteotomy using broad dynamic compression plate

Background:

Displaced intracapsular femoral neck fractures continue to be a difficult problem to treat. Various treatment modalities and their modifications have been proposed to improve the outcome. Osteosynthesis and primary valgus angulation osteotomy is one of them. Technique and outcome in a consecutive series of recent intracapsular femoral neck fractures in young adults, from a single center, is presented.

Materials and Methods:

Fifty-five patients of recent (<3 weeks old) displaced intracapsular fracture neck femur (Garden III and IV, Pauwels III, with or without comminution) in the age group 20-50 years (mean 35.4±10.4 years) were subjected to osteosynthesis and primary valgus intertrochanteric osteotomy using contoured broad dynamic compression plate (DCP). The patients were followed up from two to six years (mean 4.6 years).

Results:

Fifty-one fractures united by six months of the index procedure (92.7% union range). Avascular necrosis (AVN) developed in six patients (11%). The other complications were shortening (six), coxa vara (two), infection (two) and delayed union at osteotomy site (one). Excellent results were achieved in 48, good/fair in four and poor in three patients.

Conclusion:

Osteosynthesis with cancellous screw and primary valgus intertrochanteric osteotomy stabilized by a contoured broad DCP is a simple, easy to perform, biological treatment. Failure in a particular case can be treated with any appropriate second procedure.

Critical appraisal of the revised Ghent criteria for diagnosis of Marfan syndrome

Radonic T, de Witte P, Groenink M, de Bruin‐Bon RACM, Timmermans J, Scholte AJH, van den Berg MP, Baars MJH, van Tintelen JP, Kempers M, Zwinderman AH, Mulder BJM. Critical appraisal of the revised Ghent criteria for diagnosis of Marfan syndrome. Marfan syndrome (MFS) is a connective tissue disorder with major features in cardiovascular, ocular and skeletal systems. Recently, diagnostic criteria were revised where more weight was given to the aortic root dilatation. We applied the revised Marfan nosology in an established adult Marfan population to define practical repercussions of novel criteria for clinical practice and individual patients. Out of 180 MFS patients, in 91% (n = 164) the diagnosis of MFS remained. Out of 16 patients with rejected diagnosis, four patients were diagnosed as MASS (myopia, mitral valve prolapse, borderline non‐progressive aortic root dilatation, skeletal findings and striae) phenotype, three as ectopia lentis syndrome and in nine patients no alternative diagnosis was established. In 13 patients, the diagnosis was rejected because the Z‐score of the aortic root was <2, although the aortic diameter was larger than 40 mm in six of them. In three other patients, the diagnosis of MFS was rejected because dural ectasia was given less weight in the revised nosology. Following the revised Marfan nosology, the diagnosis of MFS was rejected in 9% of patients, mostly because of the absence of aortic root dilatation defined as Z‐score ≥2. Currently used Z‐scores seem to underestimate aortic root dilatation, especially in patients with large body surface area (BSA). We recommend re‐evaluation of criteria for aortic root involvement in adult patients with a suspected diagnosis of MFS.
