[PMID: 37408932 PMCID: PMC10319209 DOI: 10.1016/j.heliyon.2023.e17219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 06/08/2023] [Accepted: 06/10/2023] [Indexed: 07/07/2023] Open
Abstract
Introduction Pediculosis is one of the most common annoying infections caused by parasitic lice in humans. Pyrethroids are one of the main insecticides used to treat this infection. But recently, due to the Resistance of lice to this group of insecticides, its insecticidal effects have been affected. The present study was conducted through a meta-analysis to investigate the prevalence of pyrethroid resistance against these insecticides worldwide. Methods This study was conducted as a meta-analysis of the prevalence of treatment resistance in human head lice against pyrethroid insecticides worldwide. Based on this, all articles published without a time limit until the end of June 2022 in PubMed/MEDLINE, Web of Science (ISI), Scopus, and Google Scholar databases were extracted and using random-effects meta-analysis model statistical methods in the meta-analysis, Cochrane, Index I2, and funnel plot were analyzed by STATA software. Results Twenty studies were included in the meta-analysis process. According to this, the prevalence of pyrethroid resistance insecticides in human head lice was estimated at 59% (CI95%: 50%-68%). Among pyrethroid insecticides, the highest prevalence of pyrethroid resistance against permethrin insecticide was 65%. Regarding the prevalence of Resistance by year, the prevalence before 2004 was estimated at 33%, but after 2015, this rate reached 82%. Also, the majority of pyrethroid resistance was estimated at 68% using genetic diagnosis methods and 43% using clinical diagnosis methods. Conclusion More than half of human head lice pyrethroid resistance insecticides. Based on this, it is recommended that before using this treatment method to treat human head lice Infestation, it should investigate the prevalence of pyrethroid resistance in that area, and if the majority of Resistance is high, alternative or combined treatment methods should be used.

Abstract
BACKGROUND Calciphylaxis is a potentially life-threatening condition involving painful necrotic skin ulcerations, especially of the lower extremities. It is generally associated with chronic kidney failure but may be seen in nonuremic cases. CASE REPORT We report a case of calciphylaxis in a 60-year-old man with diabetes on dialysis for end-stage renal disease and known to have other typical combination of risk factors associated with calciphylaxis syndrome. On examination, he presented with multiple intensely painful calciphylaxis wounds on his legs and ankles. Despite regular wound management of his condition in our ambulatory care setting, his ulcers deteriorated. The patient's pain also increased and he was referred for hospital admission. CONCLUSION This case presentation emphasizes the importance of an interdisciplinary team in the treatment of the complex, life-threatening cutaneous manifestations of calciphylaxis. When indicated, prompt referral to a hospital setting is necessary for appropriate care.

Abstract
OBJECTIVE To define concomitant risk factors, treatment, and outcomes for patients with nonnephrogenic calciphylaxis (NNC). PATIENTS AND METHODS A retrospective review of Massachusetts General Hospital (MGH) medical records (January 1, 2014, through February 29, 2016) and a systematic literature review of PubMed, Google Scholar, EMBASE, MEDLINE, and CENTRAL (August 1, 1970, through July 31, 2016) were performed. Demographic characteristics and concomitant features were summarized and compared between patients with different lesion characteristics. Outcomes (lesion improvement and mortality) and their predictors were analyzed. RESULTS Nine patients (median age, 72 years [interquartile range (IQR), 44-82 years]; 78% women; 89% white race) were identified through MGH records. The literature review identified 107 patients (median age, 60 years [IQR, 49-72 years]; 77% women; 86% white race). Vitamin K antagonism and obesity were the most common concomitant factors. In the literature review, lower age (P<.001) and higher body mass index (P=.03) were associated with the central location of lesions, whereas vitamin K antagonism was associated with the peripheral location (P=.009). In the MGH series, median survival was 24.0 months (95% CI, 7.8-36.0 months), and 33% (95% CI, 14%-60%) had lesion improvement by 6 months. In the literature review, median survival was 4.2 months (95% CI, 1.9-5.9 months), median time to lesion improvement was 5.9 months (95% CI, 3.9-8.9 months), and none of the treatments were associated with lesion improvement or survival. CONCLUSION This description of concomitant traits may augment an earlier recognition of NNC. Future research is needed to investigate NNC pathogenesis and treatments.

Abstract
Skin self-examination (SSE) is a crucial preventive health behaviour in melanoma survivors, as it facilitates early detection. Physician endorsement of SSE is important for the initiation and maintenance of this behaviour. This study focussed on the preliminary validation of a new nine-item measure assessing physician support of SSE in melanoma patients. English and French versions of this measure were administered to 188 patients diagnosed with melanoma in the context of a longitudinal study investigating predictors and facilitators of SSE. Structural validity was investigated using exploratory factor analysis conducted in Mplus and convergent and divergent validity was assessed using bivariate correlations conducted in spss. Results suggest that the scale is a unidimensional and reliable measure of physician support for SSE. Given the uncertainty regarding the optimal frequency of SSE for at-risk individuals, we recommend that future psychometric evaluations of this scale consider tailoring items according to the most up-to-date research on SSE effectiveness.

Abstract
OBJECTIVES We illustrate the important and troubling issue of persistent misinformation and false claims in the medical literature using a frequently cited case inaccurately believed by many to be the first case of calciphylaxis. METHODS We identified a recurring error in the medical literature in the form of numerous citations of a study from the 1890s of a 6-month-old child with idiopathic infantile arterial calcification that is purported to be the first description of a case of calciphylaxis. We performed searches to determine the frequency of this error. Google Scholar and PubMed were searched for references citing the Bryant and White article. Accuracy of the citations was determined. RESULTS A Google Scholar search identified 33 references that incorrectly cite the Bryant and White article as the first description of a case of calciphylaxis. Of the 100 most recent PubMed publications on calciphylaxis, we identified five studies that incorrectly attribute the Bryant and White article as the first description of calciphylaxis, which accounts for approximately 5% of the contemporary literature on this topic. CONCLUSIONS Medical misinformation such as this is frequently perpetuated. We propose that computational resources could be better used to flag erroneous and contradicted claims to update and correct the literature.

Abstract
Calciphylaxis, or calcific uremic arteriolopathy, is a vascular ossification-calcification disease involving cutaneous or visceral arterioles, with ischemic damage of the surrounding tissues, usually in the setting of chronic kidney disease. Pathogenesis is still unclear and probably comprises the participation of vascular smooth muscle cells, endothelial cells and macrophages surrounded by a uremic and/or pro-calcifying environment. According to the original concept of calcific uremic arteriolopathy coined by Hans Selye, risk factors may be divided into sensitizers and challengers and their knowledge is useful in clinical practice to pre-emptively identify both uremic and non-uremic 'at risk' patients and guide treatment. Systemic calcific uremic arteriolopathy is a rarity. Cutaneous calcific uremic arteriolopathy is more frequent and clinically presents as a first phase of cutaneous hardening and erythema, followed by a second phase of ulcerations and scars; these two phases are probably associated with the initial development of arteriolar lesion and tissue ischemic damage, respectively. Clinical history, physical examination, laboratory analysis, histology and imaging are the main tools to exclude important differential diagnoses and obtain a definitive diagnosis. Treatment is generally unrewarding and consists of rigorous control of comorbid conditions, anti-oxidant, anti-inflammatory and antithrombotic strategies, avoidance of iatrogeny and wound and pain management. Prognosis remains poor in terms of morbidity and mortality. Efforts should be made towards a greater awareness of calcific uremic arteriolopathy, development of better therapies and improvement of clinical outcomes.

Abstract
Calciphylaxis or calcific arteriolopathy is a rare, life-threatening obstructive pathology of the small cutaneous and subcutaneous vessels. It mainly affects patients with chronic renal failure but it also has been described in patients with normal renal function. The principal risks factors apart from renal failure and phosphocalcic metabolism imbalance are: the female sex, obesity, peripheral vascular disease, diabetes and oral anti-coagulation. We present a very rare case of abdominal, mammarian and upper thighs calciphylaxis in a patient with normal renal function. She presented a severe obesity with a recent important loss of weight and had been treated by oral anticoagulants for a long time. She benefited of a multidisciplinary approach with dermatologists, plastic surgeons and anesthesists permitting a recovery in fourteen weeks. Multidisciplinary approach is necessary but the place of the surgery is not well defined. We report a case in which early and wide surgical approach permitted to obtain a favourable evolution of the pathology. Then, we propose a therapeutic strategy after review of the literature.
