The Aging Males' Symptoms (AMS) scale: Update and compilation of international versions

Background

The interest of clinical research in aging males increased in recent years and thereby the interest to measure health-related quality of life (HRQoL) and symptoms of aging men. The Aging Males' Symptoms scale (AMS) became the most commonly used scale to measure HRQoL and symptoms in aging males in many countries worldwide. The aim of this paper is to review the current state of the instrument particularly concerning versions of the scale in different languages in the light of the quality of the translation process.

AMS versions available

Most of the translations were performed following international methodological recommendations for linguistic & cultural adaptation of HRQoL instruments. Mainly the English version was used as source language for the translation into Dutch, Spanish, Portuguese, Italian, Swedish, and Japanese (attached as additional PDF-files). Preliminary versions that were derived only from forward translations are of secondary quality and available in Finnish, Flemish, and Russian. It is recommended to complete the translation process for the latter languages before using them in international studies.

Translations in process

The AMS scale is in the process of consensus finding of two existing French versions, and the versions in the Korean, Thai, and Indonesian languages have not yet been completed in the translation process.

Conclusion

The AMS scale is obviously a valuable tool for assessing health related quality of life in aging men, because it is used worldwide. It is a standardized scale according to psychometric norms. Most of the currently available language versions were translated following international standards for linguistic and cultural translation of quality of life scales. Assistance is offered to help interested parties in the translation process.     

Pericardial tamponade caused by Pasteurella multocida infection after a cat bite

An unusual case of meningitis and pericardial tamponade caused by Pasteurella multocida after a cat bite is reported. The patient was successfully treated by antibiotics and pericardiocentesis and made an uneventful recovery from a life threatening condition. This case illustrates the potential dangers that can arise from a seemingly trivial and commonplace injury.     

<Emphasis Type="Italic">BRCA1</Emphasis> and <Emphasis Type="Italic">BRCA2</Emphasis> mutations in a population-based study of male breast cancer

Background

The contribution of BRCA1 and BRCA2 to the incidence of male breast cancer (MBC) in the United Kingdom is not known, and the importance of these genes in the increased risk of female breast cancer associated with a family history of breast cancer in a male first-degree relative is unclear.

Methods

We have carried out a population-based study of 94 MBC cases collected in the UK. We screened genomic DNA for mutations in BRCA1 and BRCA2 and used family history data from these cases to calculate the risk of breast cancer to female relatives of MBC cases. We also estimated the contribution of BRCA1 and BRCA2 to this risk.

Results

Nineteen cases (20%) reported a first-degree relative with breast cancer, of whom seven also had an affected second-degree relative. The breast cancer risk in female first-degree relatives was 2.4 times (95% confidence interval [CI] = 1.4–4.0) the risk in the general population. No BRCA1 mutation carriers were identified and five cases were found to carry a mutation in BRCA2. Allowing for a mutation detection sensitivity frequency of 70%, the carrier frequency for BRCA2 mutations was 8% (95% CI = 3–19). All the mutation carriers had a family history of breast, ovarian, prostate or pancreatic cancer. However, BRCA2 accounted for only 15% of the excess familial risk of breast cancer in female first-degree relatives.

Conclusion

These data suggest that other genes that confer an increased risk for both female and male breast cancer have yet to be found.

     

Antibody-mediated marrow failure after allogeneic bone marrow transplantation

Marrow graft failure observed in association with histocompatibility differences between donor and recipient is often attributed to rejection mediated by host-derived cytolytic T lymphocytes. The data presented in this report indicate that persistent host antibodies specific for donor antigen may also mediate graft failure, either by antibody-dependent cell-mediated cytotoxicity (ADCC), or complement- mediated cytotoxicity. In the case of HLA Class I disparity, where all donor cells express the target antigen, the presence of alpha-donor antibody was associated with complete graft failure and death. In the case of ABO blood group antigen disparity, the presence of alpha-donor antibody resulted in erythroid hypoplasia. The latter cases proved informative insofar as they established that host antibodies could persist for more than 18 months after chemoradiotherapy and impair marrow function.     

Methotrexate/narrowband UVB phototherapy combination vs. narrowband UVB phototherapy in the treatment of chronic plaque‐type psoriasis – a randomized single‐blinded placebo‐controlled study

Background Psoriasis is a chronic, recurring inflammatory disease affecting the skin, joints and nails that has a significant negative impact on the quality of life. Efficacy of combination of methotrexate/narrowband ultraviolet B (NBUVB) phototherapy in the treatment of psoriasis has been rarely assessed. Objectives To compare the efficacy of methotrexate/NBUVB phototherapy combination vs. NBUVB phototherapy in the treatment of chronic plaque psoriasis. Methods Forty patients with chronic plaque‐type psoriasis (body surface area involvement >10%) were randomized to receive either methotrexate/NBUVB phototherapy (group A) or placebo/NBUVB phototherapy (group B). End point of treatment was 75% reduction in Psoriasis Area and Severity Index (PASI) Score or upto 6 months, whichever was earlier. Patients were then followed up for a period of 12 weeks for assessment of relapse. Results Of 40 patients, 37 completed the treatment period and 29 both the treatment period and follow‐up. PASI 75 was achieved in 19/20 patients in group A and 14/20 patients in group B (P < 0.04). The mean number of weeks(P = 0.001), the mean cumulative dose of NBUVB (P = 0.001) and the mean number of phototherapy sessions (P = 0.0001) required to achieve PASI 75 were significantly less in group A compared with group B. There was no significant difference in the number of patients who relapsed during the follow‐up period (P = 0.68). Conclusion Combination of methotrexate and NBUVB phototherapy provides more rapid clinical improvement compared with NBUVB monotherapy in the treatment for chronic plaque‐type psoriasis.
