Validation of the German version of the ‘Hypogonadism Related Symptom Scale’ (HRS) in andrological patients with infertility,HIV infection and metabolic syndrome

As commonly used self‐reported screening instruments for male hypogonadism demonstrated lack of specificity, a Hypogonadism Related Symptom Scale (HRS) was developed in 2009 as a novel self‐rating screening tool. As the questionnaire has not been validated, the purpose of our study was to perform a validation in patients presenting with different disorders (e.g. infertility, HIV infection or metabolic syndrome) and disease‐related risk to develop hypogonadism. Two hundred and eighteen patients aged 19–71 years (40.1 ± 9.5) who completed the HRS and other common questionnaires [International Index Of Erectile Function (IIEF), National Institutes of Health Chronic Prostatitis Symptom Index (NIH‐CPSI), Hospital Anxiety and Depression Scale (HADS), short form (SF)‐12] were included. In all patients, blood levels of total testosterone, luteinizing hormone, follicle‐stimulating hormone, oestradiol and sex hormone‐binding globulin were determined and free testosterone was calculated. Cronbach's α for the scale was 0.896, split‐half 0.871 for the 1st half and 0.807 for the 2nd half. Spearman–Brown coefficient was 0.767, and Guttman split‐half coefficient was 0.759. Consistent correlations were found between HRS and IIEF5 (ρ = 0.57, P < 0.001), and HADS (ρ = ?0.6, P < 0.001). In addition, HRS was significantly correlated with total testosterone (ρ = 0.135, P < 0.05), free testosterone (ρ = 0.148, P < 0.05) and oestradiol (ρ = ?0.134, P < 0.05). Our validation study confirms the data from the initial development of the HRS questionnaire. Clinicians might have an additional advantage from the HRS when investigating males with suspected hypogonadism.     

Paratesticular liposarcoma: Two case reports

BACKGROUNDParatesticular liposarcoma accounts for approximately 7% of scrotal tumors. They are rare lesions of the reproductive system with approximately 90% of the lesions originating from the spermatic cord. Surgery, with the goal of complete resection, is the mainstay for treatment of this disease. However, treatment consisting of extended resection to decrease local recurrence remains controversial.CASE SUMMARYWe report the cases of two patients with paratesticular liposarcomas who were treated with radical testicular tumor resection without adjuvant therapy. Follow-up investigations at 9 mo showed no sign of recurrence.CONCLUSIONSurgery is the first-line treatment, regardless of whether it is a recurrent or primary tumor. Extended resection carries a higher risk of complications and should not be performed routinely. Preoperative radiotherapy can reduce the local recurrence rate without affecting the overall survival.     

Factors Related to Osteosarcopenia in Kidney Transplant Recipients

Introduction

Sarcopenia and osteopenia are highly prevalent in older patients, and are associated with a high risk for falls, fractures, and further functional decline. However, related factors in kidney transplant recipients suffering from osteosarcopenia, the combination of sarcopenia and osteopenia, remain unknown.

Quality Control,Quality Assurance,and Proficiency Testing in the Andrology Laboratory

The primary goal of any andrology laboratory should be the performance of accurate, reproducible, high-quality, and clinically relevant laboratory testing. An underlining objective of such a goal is to better serve the ordering physician, and the patient, by continually improving laboratory performance. Quality control (QC) is the procedure that determines accurate and reproducible testing. Proficiency testing (PT) is the process allowing physicians to compare results from one laboratory to another. Quality assurance (QA) is the mechanism ensuring high-quality, clinically relevant testing. Together, QC, QA, and PT serve as the foundation responsible for a program that continually improves the overall quality of the testing, allowing the physician ordering the test to be more effective in treating the patient. Several examples are presented to assist the implementation of effective QC and QA programs aimed at continually improving performance in the andrology laboratory.
