Chloracne, also known as metabolizing acquired dioxin-induced skin hamartomas (MADISH), is a rare disfiguring disease related to dioxin exposure. There is a paucity of literature on the clinical manifestations and pathogenesis of chloracne/MADISH. The aim of this study was to assess the clinical features of this very unusual acneiform eruption and to explore the pathogenesis of the disease. This was a retrospective, observational report study was conducted on five patients belonging to the same nuclear family (father, mother and three children) and a relative (father's brother) living in the same house. Histopathological, immunohistochemical, laboratory and toxicological analyses were performed for all patients. The results suggest that CYP1A1 in human skin is a diagnostic biomarker in chloracne, and was positive for all the patients in our sample. Tetrachlorodibenzo-p-dioxin is the most investigated dioxin responsible for chloracne; however, several other agonists, whether dioxin-like or not, can activate the aryl hydrocarbon receptor. To our knowledge, this Italian case series is the first study to suggest polychlorinated biphenyls as a possible cause of an overstimulation of aryl hydrocarbons causing the consequent acneiform eruption.
To compare the influence of extracorporeal and intracorporeal ligations on the duration of and complications associated with laparoscopic ovariectomy in dogs.
Prospective randomized experimental study.
Healthy intact female dogs (n = 18).
The left and right ovarian pedicles of dogs undergoing laparoscopic ovariectomy were randomly assigned to intracorporeal (n = 18) or extracorporeal (n = 18) ligation groups. Surgeries were performed by two American College of Veterinary Surgeons (ACVS) diplomates and two ACVS residents. The time required to place extracorporeal and intracorporeal ligations, duration of surgery, and intraoperative complications were compared between ligation techniques. Postoperative complications were recorded.
The time required for intracorporeal ligation (17.3 ± 8.7 minutes) did not differ from that required for extracorporeal ligation (15.1 ± 6.1 minutes; P = .38). The total duration of surgery was 102.7 ± 28.7 minutes including portal placement and veterinary student closure of incisions. Ligation of the ovarian pedicle was successful in 16 of 17 dogs. Intraoperative hemorrhage occurred in three dogs, and postoperative complications were noted in three dogs, without apparent difference between ligation techniques.
No difference was identified between extracorporeal and intracorporeal ligations of ovarian pedicles.
This study does not provide evidence to support one ligation technique rather than the other.

To explore the experiences of the first nurses assigned to work in COVID-19 units with the onset of the outbreak in Turkey.
Even though the risks faced by nurses while performing a dangerous task during the epidemic are similar, their experiences may differ.
This qualitative study was carried out with 17 nurses. The interviews were carried out individually and online. The data were analysed using Colaizzi's phenomenological method.
From the analyses of the data, four key themes have emerged as follows 'needs', 'anger', 'questioning' and 'decision'. Needs include visibility, support, adaptation and sleep/rest. Nurses were angry because of their unmet expectations, feelings of injustice, and selfish and insensitive behaviours they faced. They questioned their profession and decided to either alienate from the profession or continue with the gains they had made.
This study found that nurses perceived an imbalance between their efforts and their achievements.
This study provides evidence for nursing managers to anticipate problems that may arise both during and after the outbreak. Nurses should be made to feel that they are valued members of the health care institution, and effective strategies should be implemented to improve their perceptions of organisational justice.

This study aimed to evaluate the prevalence of monosymotomatic nocturnal enuresis (MSNE) with reduced bladder capacity in children with primary nocturnal enuresis (NE) and to suggest treatment outcomes.
This study retrospectively evaluated 54 children (30 males, 24 females; median age 8; range 5-14) who were newly diagnosed with primary NE from November 2017 to October 2019. Reduced bladder capacity in MSNE was defined when a patient's maximal voided volume (MVV) from his or her voiding diary was 75% or less than estimated functional bladder capacity ([age + 1] x 30 mL) for his or her age and there were no daytime lower urinary tract symptoms (LUTS) as assessed using history taking and questionnaires.
Nineteen (35.2%) of 54 children with newly diagnosed primary NE did not report daytime LUTS. Fifteen children (27.8%) had a reduced bladder capacity and were prescribed anticholinergic or beta-3 agonist. After three months of medication, MVV significantly increased from 117.5 mL to 183.3 mL (P = 0.010), bureasing the bladder capacity of these patients.Airway exposure to eg particulate matter is associated with cardiovascular disease including atherosclerosis. Acute phase genes, especially Serum Amyloid A3 (Saa3), are highly expressed in the lung following pulmonary exposure to particles. We aimed to investigate whether the human acute phase protein SAA (a homolog to mouse SAA3) accelerated atherosclerotic plaque progression in Apolipoprotein E knockout (ApoE-/- ) mice. Mice were intratracheally (i.t.) instilled with vehicle (phosphate buffered saline) or 2 µg human SAA once a week for 10 weeks. Plaque progression was assessed in the aorta using noninvasive ultrasound imaging of the aorta arch as well as by en face analysis. Additionally, lipid peroxidation, SAA3, and cholesterol were measured in plasma, inflammation was determined in lung, and mRNA levels of the acute phase genes Saa1 and Saa3 were measured in the liver and lung, respectively. Repeated i.t. instillation with SAA caused a significant progression in the atherosclerotic plaques in the aorta (1.5-fold). Concomitantly, SAA caused a statistically significant increase in neutrophils in bronchoalveolar lavage fluid (625-fold), in pulmonary Saa3 (196-fold), in systemic SAA3 (1.8-fold) and malondialdehyde levels (1.14-fold), indicating acute phase response (APR), inflammation and oxidative stress. Finally, pulmonary exposure to SAA significantly decreased the plasma levels of very low-density lipoproteins - low-density lipoproteins and total cholesterol, possibly due to lipids being sequestered in macrophages or foam cells in the arterial wall. Combined these results indicate the importance of the pulmonary APR and SAA3 for plaque progression.
Acetaminophen has been increasingly used in treating patent ductus arteriosus (PDA) in preterm neonates. Variations were observed in the dosing regimen of acetaminophen across the studies. There is hardly any data available for a relatively higher dose of intravenous acetaminophen (15mg/kg/dose every 6 hours) in the preterm population. We present here the results of a prospective study with this dose of intravenous acetaminophen for treating PDA in critically ill preterm neonates.
Preterm neonates (≤37weeks of gestational age) with haemodynamically significant PDA were enrolled. Intravenous acetaminophen at 15mg/kg/dose every 6 hours was administered. Echocardiographic monitoring, liver and renal function tests were carried out. Standard definitions were adhered for defining acute kidney injury (AKI) and hepatotoxicity.
Fifty-five neonates were recruited. Following the first dose, less than half had their serum acetaminophen concentrations in the therapeutic range. Extreme preterm neonates were less liks in 78.2% of the preterm neonates with PDA. We observed a lower incidence of hepatotoxicity, and AKI in the study population. No association was observed between the serum acetaminophen concentrations and PDA closure.
The aim of this study was to assess the impact of the COVID-19 pandemic on the activity of private medical practices in Morocco.
An online survey was carried out in June 2020. The study population consisted of physicians (General practitioners and specialists) who run private practices in different regions of Morocco. MK-0752 manufacturer The questionnaire comprised three sections demographic and professional data, the impact noticed by the physicians and the strategies they adopted to tackle this impact.
We analysed 225 responses. Specialists represented 71.6% of the respondents. The majority (94.2%) of the private practices were located in urban areas. Almost all respondents have noticed a change in the demand for medical services, mainly a decrease (96.4%). There was an increase in urgent consultations (30.7%) and consultations for acute motives (39.1%). Respondents also reported less (69.3%) or no (23.1%) regular follow-up visits for patients with chronic diseases. Decreased incomes concerned 97.3% of the practices. Practitioners reacted by working less hours (87.6%), delaying some procedures (78.2%) and applying recommended safety measures (100%). Telemedicine was used in an informal way to facilitate the communication with patients.
During this pandemic, private practices were challenged to contribute to the continuity of healthcare services while ensuring the safety of the staff and the patients. Several strategies were adopted to cope with the new situation and to survive its many challenges.

Among them, compound 4d displayed the highest antiproliferative activity against four cancer cell lines with an IC50 value of 4.9 μM in B16-F10 cells. Compound 4d effectively inhibited tubulin polymerization in vitro (IC50 of 13.1 μM). Further, 4d induced cell cycle arrest in G2/M phase. Finally, 4d inhibited the migration of cancer cells in a dose-dependent manner. In summary, these results suggest that compound 4d represents a new class of tubulin inhibitors deserving further investigation.
Human transmembrane 6 superfamily 2 (TM6SF2) variant rs58542926 is associated with NAFLD and HCC. However, conflicting reports in germline Tm6sf2 knockout mice suggest no change or decreased very low density lipoprotein (VLDL) secretion and either unchanged or increased hepatic steatosis, with no increased fibrosis. We generated liver-specific Tm6Sf2 knockout mice (Tm6 LKO) to study VLDL secretion and the impact on development and progression of NAFLD.
Two independent lines of Tm6 LKO mice exhibited spontaneous hepatic steatosis. Targeted lipidomic analyses showed increased triglyceride species whose distribution and abundance phenocopied findings in mice with liver-specific deletion of microsomal triglyceride transfer protein. The VLDL triglyceride secretion was reduced with small, underlipidated particles and unchanged or increased apolipoprotein B. Liver-specific adeno-associated viral, serotype 8 (AAV8) rescue using either wild-type or mutant E167K-Tm6 reduced hepatic steatosis and improved VLDL secretion.
