Linguistic Validation of the US Spanish Work Productivity and Activity Impairment Questionnaire, General Health Version

INTRODUCTION: There are no measures of health-related absenteeism and presenteeism validated for use in the large and increasing US Spanish-speaking population. Before using a Spanish translation of an available English-language questionnaire, the linguistic validity of the Spanish version must be established to ensure its conceptual equivalence to the original and its cultural appropriateness. OBJECTIVE: The objective of this study was to evaluate the linguistic validity of the US Spanish version of the Work Productivity and Activity Impairment questionnaire, General Health Version (WPAI:GH). METHODS: A US Spanish translation of the US English WPAI:GH was created through a reiterative process of creating harmonized forward and back translations by independent translators. Spanish-speaking and English-speaking subjects residing in the US self-administered the WPAI:GH in their primary language and were subsequently debriefed by a bilingual (Spanish-English) interviewer. RESULTS: US Spanish subjects (N = 31) and English subjects (N = 35), stratified equally by educational level, with and without a high school degree participated in the study. The WPAI-GH item comprehension rate was 98.6% for Spanish and 99.6% for English. Response revision rates during debriefing were 1.6% for Spanish and 0.5% for English. Responses to hypothetical scenarios indicated that both language versions adequately differentiate sick time taken for health and non-health reasons and between absenteeism and presenteeism. CONCLUSION: Linguistic validity of the US Spanish translation of the WPAI:GH was established among a diverse US Spanish-speaking population, including those with minimal education.     

Prospective comparative study of cefotetan with piperacillin for prophylaxis against infection in elective colorectal surgery

This study compared one dose of cefotetan with three doses of piperacillin as prophylaxis against wound infection in 153 patients undergoing elective colorectal surgery. The patients were randomized into two groups: the first received 2 g cefotetan intravenously with induction of anaesthesia (n = 75), and the second received three doses of 2 g piperacillin (n = 78). Wound infection was defined as the presence of an abscess or discharging pus from the wound. In the cefotetan group there were 14 (19%) wound infections and 13 (17%) in the piperacillin group. There were three septic deaths, one in the cefotetan group and two in the piperacillin group. Both groups were comparable with regard to age, sex, nature of pathology and pre- and perioperative risk factors. No significant haematological or biochemical abnormalities were detected. The only adverse reaction was one patient who had an allergic reaction (rash) to piperacillin. These data suggest that single-dose cefotetan is as effective as triple-dose piperacillin in prophylaxis against infection in elective colorectal surgery.     

Anatomic and clinical significance of the first and most medial deep transverse metatarsal ligament

A review of the related literature revealed ambiguity and inconsistency as to the location of the first and most medial deep transverse metatarsal ligament in relation to the adjacent soft tissue and osseous structures. Seventy right sided, mid-thigh cadaveric dissections were completed by the investigators. The results consistently identified the ligament as bifurcate, bearing a common stem with the medial aspect of the second metatarsophalangeal joint capsule and a split attachment to the lateral aspect of the first metatarsophalangeal joint capsule and sesamoidal apparatus. The conjoined tendon of the adductor hallucis muscle was consistently identified as passing between this bifurcation. Knowledge of the location of this anatomic structure bears importance in the podiatric surgeon's attempt to restore the alignment of the first metatarsophalangeal joint by means of soft tissue or osseous procedures.
