Gender matter in isotretinoin therapy for acne vulgaris? A retrospective study

Introduction: Gender differences have been recently highlighted for several aspects of acne vulgaris such as epidemiology, pathogenesis, clinical course, quality of life and treatment outcome. In particular a shorter but more severe clinical course has been reported in males than in females; nevertheless, usually men have their quality of life less affected. Aim: To determine if the response and the adverse events to 1 cycle of oral isotretinoin therapy can be influenced by gender. Methods: A retrospective study was conducted on consecutive patients affected by acne vulgaris and treated with oral isotretinoin. Global acne grading system (GAGS), acne-related quality of life (AQoL) and isotretinoin-related adverse events were considered as outcome measures and were evaluated before (T0), every month during administration and 4 weeks after the withdrawal (T1) of oral isotretinoin therapy. Mann-Whitney U test and Wilcoxon signed-rank test were used for quantitative parameters and Fisher exact test for qualitative ones. Results: Forty-nine acneic patients were retrospectively selected (33 males 67.3% and 16 females -32.7%; median age: 19 years). Patients had received a median dosage of isotretinoin of 0.4 mg/kg/die for a median period of 5 months; no differences in outcome measures among genders were reported. Limitations: The study is retrospective and the sample is small and not homogenously distributed among genders, as males are double in number than females. Conclusions: In our study population gender didn't influence neither the clinical and the quality of life outcome measures nor the occurrence of adverse events to oral isotretinoin therapy for acne

Trends in cutaneous melanoma mortality in Italy from 1982 to 2016

Background In Italy, comprehensive national studies, about mortality rates for cutaneous melanoma, are missing. The aim of this study was to analyze the trend of cutaneous melanoma mortality in Italy from 1982 to 2016. Methods Data on death certificates were obtained from Italian National Institute of Statistics (ISTAT: Istituto nazionale di STATistica, Indagine sulle cause di morte). Mortality rates were age-standardized on the European population 2013 and presented per 100,000 individuals. Age-adjusted mortality rates (AMRs) were calculated by sex, age group, and geographic areas. To identify changes in mortality rate trends, a joinpoint regression model was used, and the annual percent change (APC) was estimated. Results In Italy, a total number of 49,312 patients (44.0% women) died for cutaneous melanoma from 1982 to 2016. Melanoma mortality rates significantly increased in the study period in both sexes, with higher AMR values and a steeper increase in men (from 2.71 to 4.02; APC: 1.43; 95% CI 1.26-1.61) than women (from 1.94-2.10; APC: 0.23; 95% CI 0.00-0.46). The largest difference between men and women was observed in patients aged >= 65 years with APC of 2.17 in men (95% CI 1.97-2.37) and 0.37 in women (95% CI 0.08-0.66). Conclusion In conclusion, the melanoma mortality rate in Italy progressively increased especially in elderly men. Several hypotheses might explain the observed age and geographic differences such as sun exposure habits or different strategies of prevention campaigns

Xerostomia, gustatory and olfactory dysfunctions in patients with COVID-19

Background The novel Coronavirus Disease-19 (COVID-19) continues to have profound effect on global health. Our aim was to evaluate the prevalence and characterize specific symptoms associated with COVID-19. Methods This retrospective study included 326 patients with confirmed SARS-CoV-2 infection evaluated at the Emergency Department of the Umberto I Polyclinic Hospital, Rome, Italy between March 6th and April 30th, 2020. In order to assess xerostomia, olfactory and gustatory dysfunctions secondary to COVID-19, a telephone-based a modified survey obtained from the National Health and Nutrition Examination Survey (NHANES) 2013–2014 for taste and smell disorders and the Fox Questionnaire for dry mouth were administered to 111 patients (34%) after discharge between June 4th and June 12th. Results Taste dysfunction was the most common reported symptom (59.5%; n = 66), followed by xerostomia (45.9%; n = 51) and olfactory dysfunctions (41.4%; n = 46). The most severe symptom was olfactory dysfunction with a median severity score of 8.5 (range: 5–10). Overall 74.5% (n = 38) of patients with xerostomia, 78.8% (n = 52) of patients with gustatory dysfunctions and 71.1% (n = 33) of patients with olfactory dysfunctions reported that all symptoms appeared before COVID-19 diagnosis. Overall, the majority of patients reported one symptom only (45.9%, n = 51), 37 (33.3%) reported the association of two symptoms, and 23 (20.7%) patients reported the association of three symptoms at the same time. Conclusion Xerostomia, gustatory and olfactory dysfunctions may present as a prodromal or as the sole manifestation of COVID-19. Awareness is fundamental to identify COVID-19 patients at an early stage of the disease and limit the spread of the virus

Efficacy of antiseptic mouthrinses against SARS-CoV-2: A prospective randomized placebo-controlled pilot study

Coronavirus-disease-19 (COVID-19) continues to affect millions of individuals worldwide. Antiviral activity of mouthrinses remains an important research area as the oral cavity is a site of SARS-CoV-2 initial replication. The aim of this study was to assess the effectiveness of three different mouthrinses in reducing the oral/oropharyngeal SARS-CoV-2 viral load.Objectives: Coronavirus-disease-19 (COVID-19) continues to affect millions of individuals worldwide. Antiviral activity of mouthrinses remains an important research area as the oral cavity is a site of SARS-CoV-2 initial replication. The aim of this study was to assess the effectiveness of three different mouthrinses in reducing the oral/oropharyngeal SARS-CoV-2 viral load. Methods: Adult patients, hospitalized with confirmed COVID-19 were recruited for the study. Oral/oropharyngeal baseline SARS-CoV-2 samples were collected and analyzed by Real-Time-PCR. Subsequently, patients were instructed to rinse with 1 % hydrogen peroxide (H2O2), 0.12 % chlorhexidine (CHX), 1 % povidone‑iodine (PVPI) or Sodium Chloride 0.9 % (placebo). Viral loads were measured right after (T1), and at 45 min (T2) from the rinse. Results: In the PVP-I 1 % group, 5/8 (62.5 %) patients at T1, and 3/8 (37.5 %) patients at T2, SARS-CoV-2 was not detectable in the swab specimens. In the H2O2 1 % group, 2/11 (18.2 %) patients at T1, and 2/11 (18.2 %) other patients at T2 showed no SARS-CoV-2 loads. One (12.5 %) patient in the CHX 0.12 % group showed SARS-CoV-2 negativity at T2. One (9.1 %) patient at T1, and another (9.1 %) patient at T2 showed no SARS-CoV-2 loads in the placebo group. Conclusions: Oral SARS-CoV-2 loads were reduced at T1 in the PVP-I 1 % and H2O2 1 % groups. Clinical relevance: PVP-I 1 % was the most effective rinse especially in patients with low viral copy numbers at baseline

Dermoscopy of melanoma according to different body sites: Head and neck, trunk, limbs, nail, mucosal and acral

Effective cancer screening detects early-stage tumours, leading to a lower incidence of late-stage disease over time. Dermoscopy is the gold standard for skin cancer diagnosis as diagnostic accuracy is improved compared to naked eye examinations. As melanoma dermoscopic features are often body site specific, awareness of common features according to their location is imperative for improved melanoma diagnostic accuracy. Several criteria have been identified according to the anatomical location of the melanoma. This review provides a comprehensive and contemporary review of dermoscopic melanoma criteria according to specific body sites, including frequently observed melanoma of the head/neck, trunk and limbs and special site melanomas, located on the nail, mucosal and acral region

Cardiovascular Risk Evaluation through Heart Rate Variability (HRV) Analysis in Patients with Psoriasis before and after 12 Weeks of Etanercept Therapy: A Preliminary Prospective Study

Background The association between psoriasis and cardiovascular diseases is suggested by epidemiological studies. The sub-inflammatory systemic state that characterizes both psoriasis and atherosclerosis has been proposed as the link between these conditions; it cannot, however, explain the increased incidence of sudden cardiac death reported in young patients with severe psoriasis without common cardiovascular risk factors. In a previous study we reported higher levels of autonomic dysregulation in psoriatic patients, concluding that the prevalence of the sympathetic arm over the para-sympathetic one could increase cardiovascular risk. Objectives To assess the influence of etanercept, an anti-TNFα agent, on the autonomic cardiovascular regulation in young patients with moderate-to-severe psoriasis without cardiovascular risk factors. Methods Five-minute ECG recordings were collected at rest conditions before and after 12 weeks of therapy with etanercept in 19 young psoriatic patients without cardiovascular risk factors. The Cardiolab CE pocket PC ECG system was used for linear methods of heart rate variability (HRV) analysis. Results No significant change in HRV analysis parameters was apparent after 12 weeks of etanercept therapy. Conclusion Our data suggest that treatment with etanercept in patients with moderate-to-severe psoriasis doesn\u27t affect cardiovascular autonomic regulation, and subsequently the cardiovascular risk.</p
