The Beginning of the End.

OBJECTIVES: The purpose of this study was to determine the relationship between gender, research productivity, academic rank, and departmental leadership positions of pathology faculty in North America. METHODS: The online information presented for the faculty members in all American- and Canadian-accredited pathology residency programs' official websites and Elsevier's SCOPUS were queried to assess research productivity, academic ranks, and leadership positions. RESULTS: Among 5,228 academic pathologists included in our study, there were 3,122 (59.7%) males and 2,106 (40.3%) females. Male faculty held higher academic ranks (being professor) and leadership positions (chair/program director) (P < .0001). Males were more likely to hold combined MD-PhD degrees (P < .0001) than females. The median h-index for the male faculty was 17 vs 9 for the female faculty (P = .023). CONCLUSIONS: Gender has a significant influence on leadership positions, academic ranks, and research productivity among pathology faculty members in North America.

The prevalence of anxiety and depression in patients with or without hyperhidrosis (HH).

BACKGROUND: There are conflicting data about the correlation between hyperhidrosis (HH) and anxiety and depression. OBJECTIVE: We sought to determine the prevalence of anxiety and depression in patients with or without HH. METHODS: We examined 2017 consecutive dermatology outpatients from Vancouver, British Columbia, Canada, and Shanghai, China, using Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 scales for anxiety and depression assessments. Multivariable logistic regression analysis was performed to evaluate if the impact of HH on anxiety and depression is dependent on demographic factors and diagnoses of the patients' presenting skin conditions. RESULTS: The prevalence of anxiety and depression was 21.3% and 27.2% in patients with HH, respectively, and 7.5% and 9.7% in patients without HH, respectively (P value <.001 for both). There were positive correlations between HH severity and the prevalence of anxiety and depression. Multivariable analysis showed that HH-associated increase in anxiety and depression prevalence is independent of demographic factors and presenting skin conditions. LIMITATION: The data from the questionnaires relied on the accuracy of patients' self-reports. CONCLUSION: Both single variant and multivariable analyses showed a significant association between HH and the prevalence of anxiety and depression in a HH severity-dependent manner.

Hyperhidrosis Prevalence and Demographical Characteristics in Dermatology Outpatients in Shanghai and Vancouver.

BACKGROUND: There is a wide variation in the reported prevalence of primary hyperhidrosis in the literature. Further, it is unknown if primary hyperhidrosis is a lifelong condition, or if demographical factors influence hyperhidrosis prevalence. OBJECTIVES: This study aims to examine the prevalence of hyperhidrosis in multiple ethnic groups from two ethnically diverse cities and to determine if the prevalence of primary hyperhidrosis changes according to age, gender, ethnicity, body mass index, and geographical locations. METHODS: In total, 1010 consecutive subjects attending dermatology outpatient clinics in Shanghai Skin Disease Hospital and 1018 subjects in Skin Care Center of Vancouver General Hospital were invited to fill out a questionnaire on their presenting concerns, demographical information, and sweating symptoms. The subjects were then classified to have primary hyperhidrosis using the criteria of International Hyperhidrosis Society, late-onset hyperhidrosis, or no-hyperhidrosis. The prevalence of primary HH and late-onset HH was calculated for the entire study population and in subgroups stratified according to age of examination, sex, ethnicity, presenting diagnosis, body mass index, and specific study cities. Multivariate logistic regression analyses were performed to assess the impact of these factors on HH prevalence. RESULTS: The prevalence of primary hyperhidrosis is very similar in Shanghai and in Vancouver, at 14.5% and 12.3% respectively. In addition, 4.0% of subjects in Shanghai and 4.4% subjects in Vancouver suffer from late-onset HH. Primary HH has highest prevalence in those younger than 30 years of age, decreasing dramatically in later years. Caucasian subjects are at least 2.5 times more likely to develop axillary hyperhidrosis compared to Chinese subjects. Obesity does not have much influence on primary HH presentation, although it does increase significantly the development of late-onset HH. Finally, there is no major difference of hyperhidrosis between Chinese subjects in Shanghai and Vancouver. LIMITATIONS: The data were gathered according to patients' self-reports only and the sample size was relatively small in some groups after stratification for gender, ethnicity and age. CONCLUSION: Prevalence of primary HH and late-onset HH is similar in dermatology outpatients independent of geographical locations. However, certain specific HH subtypes can show great variations according to ethnicity, age, body mass index and sex.
