Characterizing Possible Acute Brain Injury in Women Experiencing Intimate Partner Violence: A Retrospective Chart Review.

Survivors of intimate partner violence (IPV) often experience violent blows to the head, face, and neck and/or strangulation that result in brain injury (BI). Researchers reviewed the de-identified forensic nursing examination records of 205 women. More than 88% of women were subjected to multiple mechanisms of injury with in excess of 60% experiencing strangulation. About 31% disclosed various symptoms consistent with BI. Women experiencing strangulation were 2.24 times more likely to report BI-related symptoms compared to those who reported no strangulation. In conclusion, women experiencing IPV are prone to BI suggesting early screening and appropriate management are warranted.

Discrepancies in Skin Cancer Screening Reporting Among Patients, Primary Care Physicians, and Patient Medical Records.

Skin cancer incidence in the United States has risen rapidly in recent decades, underscoring the need for accessible and effective prevention practices. The full-body skin examination (FBSE) is the quintessential tool for secondary skin cancer prevention, but the US Preventive Services Task Force (USPSTF) states there is insufficient evidence to recommend the examination for the general or at-risk population. Variable performance of FBSEs among primary care providers (PCPs) is a barrier to accurate studies, and variability in measurement of that performance can be a major impediment to assessment of FBSEs in practice. To better understand the degree of variability, we performed a multicenter, cross-sectional study of FBSEs reported among 53 PCPs and 3343 patients. The results highlight the need for standardization of FBSEs and more rigorous criteria for skin cancer screening.

A striking presentation of pustular Sweet syndrome induced by trimethoprim-sulfamethoxazole.

We describe a strikingly robust presentation of trimethoprim-sulfamethoxazole (TMP-SMX)-induced pustular Sweet syndrome and discuss how to distinguish it from iododerma and other neutrophil-rich conditions. A review of the literature indicates that TMP-SMX-induced Sweet syndrome (SS) may have higher rates of neutrophilia and greater ocular, mucosal, and musculoskeletal involvement compared to SS from other drugs. Recognizing these features and identifying the offending agent are critical for correctly diagnosing TMP-SMX-induced SS in a timely manner.

Incongruence between Physician, Patient, and Medical Chart Report of Skin Cancer Prevention Counseling.

Skin cancer incidence in the United States has risen rapidly in recent decades, underscoring the need for accessible and effective prevention practices. Skin cancer prevention counseling can lead to increased sun protective behavior and early detection; however, little is understood regarding the frequency and content of counseling among primary care providers (PCPs). We performed multi-center cross-sectional surveys among 53 providers and 3343 of their patients and chart review asking whether skin cancer prevention counseling occurred and details of that counseling. Only 10−25% of patients reported that counseling occurred. Among the providers who reported counseling, there were higher odds that their patients recollected they were advised to use sunscreen or protective clothing, on how to use sunscreen, on signs of skin cancer, to perform a self-skin exam (all p < 0.001), and were provided with written materials (p < 0.01). Eight percent of prevention counseling was chart documented despite being highly associated with patient and physician recollection of counseling (p < 0.001). These results highlight the need for consistent and clear delivery of skin cancer primary prevention.

A Prospective Study of Toenail Trace Element Levels and Risk of Skin Cancer.

BACKGROUND: Few epidemiologic studies have investigated trace element exposure and skin cancer risk. METHODS: Toenail levels of mercury, selenium, chromium, iron, and zinc were measured from 6,708 women in the Nurses' Health Study (1984-2012) and 3,730 men in the Health Professionals Follow-up Study (1986-2012) with data from prior nested case-control studies. Participants were free of skin cancer at toenail collection and followed for incident basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. Cox proportional hazards models were used to compute hazard ratios (HR) and 95% confidence intervals (CI) of skin cancer associated with the elements in each study. We calculated pooled multivariable HRs using a fixed-effects model. During 26 to 28 years of follow-up, 2,433 BCC, 334 SCC, and 130 melanoma cases were documented. RESULTS: Higher toenail mercury levels were associated with risk of BCC [pooled HR for top vs. bottom quintiles = 1.34 (95% CI, 1.18-1.52), P trend < 0.0001]. Similar direct associations were found with risks of SCC [pooled HR for top vs. bottom quartiles = 1.41 (95% CI, 1.03-1.94), P trend = 0.04] and melanoma [pooled HR for top vs. bottom quartiles = 1.88 (95% CI, 1.12-3.16), P trend = 0.02]. Chromium was positively associated with BCC in women only. No associations were found between other metals and skin cancer risk. CONCLUSIONS: Our prospective data found that increased toenail mercury concentrations were associated with increased skin cancer risk. IMPACT: If our novel findings are confirmed, mercury may play a role in skin carcinogenesis.

Host Characteristics and Risk of Incident Melanoma by Breslow Thickness.

BACKGROUND: Several host characteristics, including pigmentary traits (hair color, sunburn susceptibility and tanning ability), number of common nevi (moles), and family history of melanoma, have been associated with risk of melanoma. METHODS: We prospectively examined the associations between host characteristics and risk of incident melanoma by Breslow thickness (≤1 mm, thin melanoma; or >1 mm, "thicker melanoma") based on the Nurses' Health Study (NHS, n = 86,380 women), NHS II (n = 104,100 women), and Health Professionals Follow-up Study (HPFS, n = 46,934 men). RESULTS: During 22-30 years' follow-up, a total of 1,813 incident melanoma cases were identified with information on Breslow thickness, 1,392 (76.8%) of which had thin melanoma. No significant differences were observed for thin and thicker melanoma in associations with hair color, sunburn susceptibility, and tanning ability. However, we found significant differences for the association with family history of melanoma, with a higher risk estimate for thicker melanoma [HR = 2.55; 95% confidence interval (CI): 1.91-3.42] than thin melanoma (HR = 1.59; 95% CI: 1.21-2.08; P heterogeneity = 0.02). Interestingly, women and men displayed differential associations between nevi count and risk of melanoma by Breslow thickness, with the association appearing stronger for thicker melanoma than thin melanoma in men (P heterogeneity = 0.01), but not in women. CONCLUSIONS: Individuals with family history of melanoma may be more likely to develop thicker melanoma. Men with high number of common nevi may tend to develop thicker melanoma, which was not found for women. IMPACT: The findings further stress the risk of thicker melanoma for individuals with a family history of melanoma and men with a high nevi count.

Exposure to Trace Elements and Risk of Skin Cancer: A Systematic Review of Epidemiologic Studies.

Exposure to environmental trace elements has been studied in relation to many cancers. However, an association between exposure to trace elements and skin cancer remains less understood. Therefore, we conducted a systematic review of published epidemiologic literature examining the association between exposure to trace elements, and risk of melanoma and keratinocyte carcinoma in humans. We identified epidemiologic studies investigating exposure to arsenic, cadmium, chromium, copper, iron, selenium, and zinc and risk of skin cancer in humans. Among the minerals, arsenic, selenium, and zinc had more than five studies available. Exposure to arsenic was associated with increased risk of keratinocyte carcinoma, while too few studies existed on melanoma to draw conclusions. Exposure to selenium was associated with possible increased risk of keratinocyte carcinoma. Studies of zinc and skin cancer were case-control in design and were found to have inconsistent associations. The data on the association between cadmium, chromium, copper, and iron and risk of skin cancer remain too sparse to draw any conclusions. In summary, epidemiologic studies on exposure to trace elements and cutaneous malignancies are limited. Studies with larger sample sizes and prospective designs are warranted to improve our knowledge of trace elements and skin cancer.

Psychosocial consequences of skin cancer screening.

Screening for melanoma may save lives, but may also cause patient distress. One key reason that preventative visual skin examinations for skin cancer are not currently recommended is the inadequate available evidence to assess potential harm to psychosocial wellbeing. We investigated potential psychological harms and benefits of skin examinations by conducting telephone surveys in 2015 of 187 screened participants; all were ≥35 years old. Participants had their skin examined by practitioners who had completed INFORMED, a validated web-based training for detection of skin cancers, particularly melanoma. Participants underwent the Spielberger State-Trait Anxiety Inventory (STAI), Psychological Consequences of Screening (PCQ), Hospital Anxiety and Depression (HAD) scale, and the 12-Item Short Form Health Survey (SF-12). Analyses were conducted in 2017. Of the entire study sample, 40% were thoroughly screened as determined by patient-reported level of undress and skin areas examined. Participants who were thoroughly screened: did not differ on negative psychosocial measures; scored higher on measures of positive psychosocial wellbeing (PCQ); and were more motivated to conduct monthly self-examinations and seek annual clinician skin examinations, compared to other participants (p < 0.05). Importantly, thoroughly screened patients were more likely to report skin prevention practices (skin self-examinations to identify a concerning lesion, practitioner provided skin exam), recommend skin examinations to peers, and feel satisfied with their skin cancer education than less thoroughly screened individuals (p < 0.01). Our results suggest that visual screening for skin cancer does not worsen patient psychosocial wellbeing and may be associated with improved skin cancer-related practices and attitudes.

Body dysmorphic disorder in the cosmetic practice.

Body dysmorphic disorder (BDD) is a preoccupation with a slight or imagined flaw in appearance that causes significant distress and impairment in daily functioning. The disease is more prevalent among patients who seek aesthetic procedures as compared with population standards or individuals that are not interested in aesthetic surgery. Several studies have indicated that BDD symptoms typically worsen after an aesthetic procedure because the preoccupation shifts to a different body area. This review discusses the demographic and clinical features, psychiatric comorbidity, assessment, differential diagnosis, and management of BDD. Components of the assessment include the interview, patient observation in the office, and questionnaires. The article includes a detailed discussion on questionnaires, especially those that are most useful in the dermatology or cosmetic practice. Ethical considerations in the management of BDD are discussed. BDD should not be missed by health providers because of the associated high morbidity that includes an increased suicidality. The cosmetic provider's approach should motivate BDD patients to participate in treatment, a combination of psychotherapy and pharmacotherapy.

Genital diseases in the mature woman.

Vulvovaginal conditions are common in mature women. This reflects age-related changes in immunity and skin barrier function of vulvovaginal tissues. Vaginal atrophy is commonly complicated by dryness and inflammation, which makes postmenopausal atrophic vaginitis a virtually ubiquitous condition. The differential of vaginitis includes inflammatory, infectious, and malignant diseases, plus drug hypersensitivity. Atrophic vaginitis is treated with estrogen replacement therapy. Vulvovaginal malignant melanoma occurs predominantly in postmenopausal women and carries a poor prognosis. Similarly, the incidence of vulvovaginal malignancies, such as squamous cell carcinoma and extramammary Paget disease, rises exponentially after 65 years of age. Early diagnosis of these malignancies is of utmost importance. Lichen sclerosus et atrophicus and vulvovaginal candidosis are among the most common postmenopausal vulvovaginal conditions. Lichen sclerosus et atrophicus is associated with significant morbidity, and its management can be challenging. The incidence of vulvovaginal candidosis increases in patients on estrogen replacement therapy.

The endocrine disrupting potential of monosodium glutamate (MSG) on secretion of the glucagon-like peptide-1 (GLP-1) gut hormone and GLP-1 receptor interaction.

Monosodium glutamate (MSG) is a suspected obesogen with epidemiological evidence positively correlating consumption to increased body mass index and higher prevalence of metabolic syndrome. ELISA and high content analysis (HCA) were employed to examine the disruptive effects of MSG on the secretion of enteroendocrine hormone glucagon-like peptide-1 (GLP-1) and GLP-1 receptor (GLP-1R), respectively. Following 3h MSG exposure of the enteroendocrine pGIP/neo: STC-1 cell line model (500µg/ml) significantly increased GLP-1 secretion (1.8 fold; P≤0.001), however, 72h exposure (500µg/ml) caused a 1.8 fold decline (P≤0.05). Also, 3h MSG exposure (0.5-500µg/ml) did not induce any cytotoxicity (including multiple pre-lethal markers) but 72h exposure at 250-500µg/ml, decreased cell number (11.8-26.7%; P≤0.05), increased nuclear area (23.9-29.8%; P≤0.001) and decreased mitochondrial membrane potential (13-21.6%; P≤0.05). At 500µg/ml, MSG increased mitochondrial mass by 16.3% (P≤0.01). MSG did not agonise or antagonise internalisation of the GLP-1R expressed recombinantly in U2OS cells, following GLP-1 stimulation. In conclusion, 72h exposure of an enteroendocrine cell line at dietary levels of MSG, results in pre-lethal cytotoxicity and decline in GLP-1 secretion. These adverse events may play a role in the pathogenesis of obesity as outlined in the obesogen hypothesis by impairing GLP-1 secretion, related satiety responses and glucose-stimulated insulin release.

Human pharmacokinetics and interconversion of enantiomers of MK-0767, a dual PPARalpha/gamma agonist.

MK-0767, a dual peroxisome proliferator-activated receptor (PPAR) alpha/gamma agonist, has been studied as a potential treatment of type 2 diabetes and dyslipidemia. The pharmacokinetics and interconversion of (+)-(R)-MK-0767 and (-)-(S)-MK-0767 were evaluated following oral administration of each single enantiomer and the racemate to healthy subjects. The results demonstrate that, consistent with in vitro experiments, chiral inversion occurs rapidly in vivo, and interconversion equilibrium favors (+)-(R). After all treatments, a stable ratio (R/S) of 2 to 2.5 was achieved within 8 hours in most individuals, congruent with model-based estimates of interconversion half-life. In addition, the pharmacokinetics of each enantiomer were generally similar regardless of treatment. Modeling and simulation of enantiomer disposition suggest that the observed predominance of (+)-(R)-MK-0767 in plasma may result from differential volumes of distribution between (-)-(S) and (+)-(R), preferential conversion from (-)-(S) to (+)-(R), or a combination of these, but not faster clearance of (-)-(S) compared to (+)-(R).
