Telogen Effluvium

Telogen effluvium (TE) is a noninflammatory disease characterized by diffuse loss of telogen hair. It is the most frequent cause of diffuse hair loss and the actual incidence of the disease is not known. According to the underlying etiology, TE could be physiologically and pathologically classified. The evaluation of a patient with TE includes a detailed history, physical examination, and laboratory tests. The patients should be questioned in terms of TE subtype, duration, and clinical course of hair loss. The most important point in the treatment of TE is to consult about the natural course of the disease

The Dermatological Spectrum of Coronavirus Disease-19 Disease: Cutaneous Signs for Diagnostics and Prognosis and an Expanded Classification: COVID-19 and skin

During severe acute respiratory syndrome coronavirus (CoV)-2- induced CoV disease (COVID)-19 pandemic cutaneous signs of the disease gained increasing interest for early diagnosis, to establish a prognosis and for differential diagnoses. The present review aims to summarize current knowledge on cutaneous findings in COVID-19. The findings are classified and described clinically. The spectrum of cutaneous signs include acro-ischemic lesions, rash, chilblain-like eruptions, and androgenetic alopecia. Their significance is given, and treatment options are presented. This may allow the clinicians to support triage and optimal treatment for COVID-19 patients. Key Bullets • _The COVID-19 pandemic has affected patients world-wide. Despite the leading symptoms are in the respiratory, cardiovascular, hematologic, and neurologic systems, cutaneous manifestations are increasingly be observed. • _Cutaneous findings in COVID-19 patients may have prognostic and therapeutic consequences. This review attempts to classify cutaneous symptoms, document the observed frequency of their occurrence, the significance for triage of COVID-19-patients, and the treatment of cutaneous manifestations

Increased P-wave dispersion in patients with newly diagnosed lichen planus

OBJECTIVE: Lichen planus is a chronic inflammatory autoimmune mucocutaneous disease. Recent research has emphasized the strong association between inflammation and both P-wave dispersion and dyslipidemia. The difference between the maximum and minimum P-wave durations on an electrocardiogram is defined as P-wave dispersion. The prolongation of P-wave dispersion has been demonstrated to be an independent risk factor for developing atrial fibrillation. The aim of this study was to investigate P-wave dispersion in patients with lichen planus. METHODS: Fifty-eight patients with lichen planus and 37 age- and gender-matched healthy controls were included in this study. We obtained electrocardiographic recordings from all participants and used them to calculate the P-wave variables. We also assessed the levels of highly sensitive C-reactive protein, which is an inflammatory marker, and the lipid levels for each group. The results were reported as the means ± standard deviations and percentages. RESULTS: The P-wave dispersion was significantly higher in lichen planus patients than in the control group. Additionally, highly sensitive C-reactive protein, LDL cholesterol, and triglyceride levels were significantly higher in lichen planus patients compared to the controls. There was a significant positive correlation between highly sensitive C-reactive protein and P-wave dispersion (r = 0.549,

Chemerin as a marker of subclinical cardiac involvement in psoriatic patients

Background: Chemerin has been associated with psoriasis and inflammation, but there are no studies demonstrating an association between chemerin and subclinical cardiac involvement in psoriatic patients. Therefore, the present study aimed to evaluate whether psoriatic patients with increased epicardial fat tissue, impaired flow-mediated dilatation, and diastolic dysfunction have higher serum chemerin levels than a healthy control group. Methods: The study included 60 psoriatic patients and 32 healthy controls. Echocardiographic parameters, epicardial fat tissue, flow-mediated dilatation, and chemerin levels were recorded for both groups. Results: The serum levels of chemerin in the psoriatic patients were significantly higher than in the control group. The diastolic function parameters, including isovolumic contraction and relaxation time, E’/A’ (early diastolic mitral annular velocity/late diastolic mitral annular velocity), and E/E’ (early diastolic peak velocity of mitral inflow/early diastolic mitral annular velocity) values, differed significantly between the groups. Epicardial fat tissue was significantly higher and flow-mediated dilatation was significantly lower in psoriatic patients than in the controls. Chemerin was significantly positively correlated with age, body mass index, systolic and diastolic blood pressures, waist circumference, E/E’, and epicardial fat tissue. Serum chemerin was significantly negatively correlated with E’, E’/A’, and flow-mediated dilatation. A multiple linear regression analysis showed that chemerin was independently correlated with E/E’. Conclusions: Psoriatic patients exhibit early subclinical atherosclerosis and diastolic dysfunction. Chemerin can be used as a marker to screen for patients with subclinical cardiac involvement

An unusual presentation: trichomycosis (trichobacteriosis) capitis in an infant

Trichomycosis (trichobacteriosis) is an asymptomatic superficial bacterial colonization of the hair shaft that is clinically characterized by pale yellowish, reddish or blackish sticky, cylindrical concretions surrounding the hair shaft in the axillary or pubic region. As far as we know, the first and only case of trichomycosis capitis was reported in a 8-year-old boy in 2011. We encountered no cases of trichomycosis in infancy in the literature. The current case displays an atypical presentation of trichobacteriosis involving head hair in a 10-month-old male infant

Dramatic response to colchicine treatment in acne fulminans patients with cytological hemophagocytosis: A case series of 12 patients

Acne fulminans is a severe form of acne with a sudden onset, rapid ulceration of the lesions, and some systemic symptoms, with or without systemic symptoms. These papulopustular lesions, whose pathogenesis is not fully understood, may exacerbate with systemic isotretinoin or may be a component of some autoinflammatory syndromes. It is recommended to control these sudden pustular attacks with systemic steroids or anti-inflammatory drugs. Here, in 12 patients with acne fulminans who developed exacerbation during systemic isotretinoin treatment and whose cytological examination revealed hemophagocytosis, colchicine treatment was started in addition to low-dose isotretinoin treatment, and a very good response was obtained to this treatment approach that did not contain systemic corticosteroids. © 2022 Wiley Periodicals LLC
