RESUMO

Demodex species are associated with many dermatological diseases, so an acaricidal agent that is effective against them and safe for skin applications may benefit many diseases. This study aims to investigate the anti-demodex potential of spilanthol, a product obtained from the Spilanthes Acmella plant, by determining the minimal effective dose for the first time in the literature. Demodex mites were obtained from 70 patients with standard superficial skin biopsy. Spilanthol extract was used at 1%, 2%, 3%, 4%, and 5%. Standard immersion oil was used for the negative control, and permethrin 5% was used for the positive control group. The dependent variable is the survival time of the mite. Comparisons with the negative control group, the anti-demodex effect demonstrated itself in all groups, creating a statistically significant difference (p < 0.001). The positive control group, had 3%, 4%, and 5% spilanthol rates which were very similar to the results with 5% permethrin (p > 0.05). Higher concentrations than 3% did not make any additional contribution to survival times. This is the first attempt to show the dose-dependent acaricidal effect of spilanthol on demodex mites. Even the 3% dose shows similar results to 5% permethrin, and no additional effect increase was observed at higher doses. Therefore, in vivo, studies may be planned with a 3% spilanthol dose for further studies.

RESUMO

The underlying mechanisms mycosis fungoides (MF)-related pruritus remain unclear, and the link between pruritus and systemic inflammation in MF is unexplored. We aimed to investigate systemic inflammation in MF patients and its potential connection to pruritus. In this retrospective study, demographic characteristics, MF stage, clinical and laboratory findings, and neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI) and pan-immune inflammation value (PIV) were assessed for all participants. Additionally, mSWAT scores, Dermatology Life Quality Index (DLQI), and pruritus presence and intensity via Visual Analogue Scale (VAS) scoring were recorded for MF patients. A total of 81 patients with early-stage MF and 50 controls were enrolled. Itching was present in 41 patients (50.6%). NLR, PLR, SII, SIRI and CRP values in the MF group were significantly higher. CRP, NLR, mSWAT and DLQI score were significantly higher in MF patients with pruritus than those without. Pruritus was positively correlated with DLQI, mSWAT, CRP, NLR, MLR and SIRI. VAS score was positively correlated with eosinophil count and DLQI. In the multivariate logistic regression model, only NLR was an independent and significant associate of pruritus in patients with MF. This study provides evidence of enhanced systemic inflammation in early-stage MF patients. Additionally, the correlation between pruritus with mSWAT scores and systemic inflammation parameters suggests a potential link between pruritus and the inflammatory milieu in MF.

RESUMO

INTRODUCTION: Middle ear cholesteatoma is a benign disease with invasive and destructive clinical behaviors. It increases the rate of both chronic otitis media complications and revision surgeries. The most effective treatment of middle ear cholesteatoma is surgical excision, and there is no medical treatment for this disease. Exploring new medical treatment options may help to create treatment alternatives instead of surgery. MATERIALS AND METHODS: Required cholesteatoma tissues for cell culture were excised from 4 different participants who underwent surgery in our clinic and agreed to give tissue for the study. Cholesteatoma-derived keratinocytes and fibroblasts were cocultured in temperature-sensitive culture dishes to make a three-dimensional (3D) cholesteatoma model. Then, the effects of 1% and 2% diclofenac sodium on viability and cell proliferation rates were examined using WST-1 and annexin-V tests. RESULTS: Cell viability and proliferation rates were found to be lower and apoptosis rates were higher in the diclofenac sodium group versus the negative and positive control groups. CONCLUSION: In this present study, we described a new 3D cholesteatoma cell culture model developed using cell sheet technology and demonstrated the efficacy of diclofenac sodium on cholesteatoma for the first time in the literature. It may be used in patients with chronic otitis media with cholesteatoma, but further studies investigating ototoxic and neurotoxic effects of this molecule are needed.

RESUMO

Milia-like idiopathic calcinosis cutis (MICC) is a very rare dermatological disorder characterized by multiple whitish to skin colored, milia-like papules, mostly found on the hands. MICC can disappear spontaneously by adulthood; therefore, its early recognition is crucial to avoiding unnecessary interventions. Herein, we present a case of MICC in a 6-year-old girl with Down syndrome.

RESUMO

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome, also known as drug-induced hypersensitivity syndrome (DHIS), is an acute, potentially life-threatening disease that includes skin rash, fever, haematological abnormalities and multiorgan involvement. Although its aetiopathogenesis is not exactly known, it is thought that inefficient drug detoxification leading to the accumulation of drug reactive metabolites causes autoimmune responses in skin and some internal organs, alters immune responses and induces reactivation of viral infections in people who have genetic predisposition. To the best of our knowledge, only one case of DRESS syndrome has been reported after delivery of the influenza vaccine, but the drug that induced the reaction in that case was sulfasalazine. We report a case of a 64-year-old woman, receiving allopurinol, who developed DRESS syndrome after taking the influenza vaccine.

RESUMO

Eruptive xanthoma (EX) is a very rare dermatosis mostly occurring due to high levels of serum triglycerides or uncontrolled diabetes mellitus. When EX is encountered, it is important to keep in mind that it could be a sign of severe underlying metabolic derangements. Early recognition can help avoid serious complications such as pancreatitis. After treatment of the underlying metabolic disorders, lesions mostly disappear without leaving scars. We present a case of a 55-year-old woman who presented with solely EX lesions and who was eventually diagnosed with diabetes mellitus and severe hypertriglyceridaemia.

RESUMO

Palmoplantar lichen planus (PPL) is an uncommon type of lichen planus (LP) that exclusively affects the palms and soles. We report a case of a 50-year-old man who had palmoplantar hyperkeratotic papules and plaques. The patient was diagnosed as a case of PPL by skin biopsy, and treated with acitretin. He showed a good response to acitretin within 2 months. Clinical appearance and some features of PPL may differ from classic LP. Acitretin may be a favourable treatment option for PPL.

RESUMO

Diabetic fibrous mastopathy is an uncommon self-limiting fibroinflammatory diseae of the breast that is seen predominantly in premenopausal women with long standing type I (insulin dependent) diabetes mellitus. In this report, we present a 29 years old female with uncontrolled diabetes mellitus presenting with bilateral breast masses which were irregular and hypoechoic on ultrasound, gradual enhancement on MRI and diagnosed as diabetic fibrous mastopathy on histopathology. It is quite difficult to distinguish it from malignancy on mammographic and ultrasonographic features or clinical findings. Correlation of the pathological features may help to make the correct diagnosis for this disease.
