Dermoscopy as a diagnostic tool to differentiate between tinea pedis and plantar psoriasis

Background: Clinical differentiation between tinea pedis and plantar psoriasis may sometimes be challenging, with consequent diagnostic delays and unnecessary therapies; in such cases histopathological analysis helps to differentiate the 2 conditions. In this study we used a dermoscope as a non-invasive tool to investigate the significance of specific dermoscopic features and to improve their non-invasive differentiation.Methods: A clinical diagnosis of plantar psoriasis/tinea pedis was made on basis of accepted literature and proved by histopathology. Image capturing was performed using a dermoscope. Based on combination of history, clinical, and dermoscopic examination conclusive diagnosis with specific dermoscopic features for each disease was achieved.Results: The 15 patients of biopsy proven tinea pedis and 17 patients of biopsy proven plantar psoriasis were selected. We found that the presence of whitish powdery scales located in the furrows with apparently uninvolved skin in between was significant in tinea pedis whereas the presence of silvery white scales on a pinkish red erythematous background with regularly distributed red dots was significant in plantar psoriasis.Conclusions: Dermoscopy showed significant patterns in tinea pedis and plantar psoriasis due to their well-known different histological and physio pathological background, with white diffuse scales reflecting the dry and hyperkeratotic nature of plantar psoriasis and the red dots signifying the pin point blood vessels seen clinically as Auspitz sign. The peculiar scaling in tinea pedis might result from the predilection of dermatophytes to proliferate in moist environment, such as the furrows.

Guidelines And Recommendations

Abstract Background and Aims Contrast-enhanced ultrasonography (CEUS) is a minimally invasive diagnostic tool available for diagnosing microvascular disturbances in tumors and many vascular pathologies. Unlike other radiological contrast agents, it is completely harmless for CKD patients and therefore it is used for the safe diagnosis of many diffuse or focal pathologies. Method We used CEUS examination in 50 CKD patients for the following pathologies: 10 atypical cysts, 15 liver focal lesions, 2 splenic focal lesions, 3 renal infarcts, 12 kidney focal lesions and 8 other organ involvements. Examination was made using a VOLUSON E8 machine (GE Medical System Kreztechnik GmbH Tiefenbach 15, Austria) with a 3.5 MHz convex array abdominal transducer. 2.4 ml of microbubble contrast-agent was administered intravenously and recording of the results were made for 3-5 minutes after injection. Results Depending on the organ vascular characteristics, contrast enhancement and/or wash-out were suggestive for the final diagnosis. In liver lesions there are three phases and in kidneys, spleen, gallbladder, adenopathies there are two vascular phases. We obtained a very good positive predictive value and sensitivity in detecting malignant lesions. Conclusion According to The EFSUMB Guidelines and Recommendations for the Clinical Practice of Contrast-Enhanced Ultrasound they are used both for hepatic and Non-Hepatic Applications. Being non-invasive and non-irradiating it could be the main diagnostic examination in CKD population in the future.

Practical Demonstration

Pulmonary hypertension is a hemodynamic disorder defined by abnormally high pulmonary artery pressure that affects the arteries in your lungs and the right side of your heart. In this study, hepatic venous duplex will be done to diagnose and quantify the PH. So that Patients can avoid unnecessary invasive right heart catheterization. This practical demonstration is the key to enrich our experience and knowledge in the field of PH. Objectives of this study was to assess PH status by Hepatic venous Duplex (HVD) as well by right heart catheterization and to compare them. This study was conducted in the Department of Cardiology, BSMMU, Shahbagh, Dhaka extending from July 2018 to December 2019. Total 100 (One hundred) subjects were enrolled in this study. It was an Observational study and includes the subjects between 18 years to 45 years of age. Results of this study shows very close proximity to that of Right heart catheterization. Hemodynamic changes in Hepatic venous duplex study could be used as an alternative diagnostic tool for evaluating moderate to severe pulmonary hypertension. This method could counteract the weakness of the currently used diagnostic methods and improve the accuracy of assessing pulmonary hypertension when combined with other methods.

Cystoid macular oedema (CMO) is a primary cause of reduced vision after cataract surgery even after uneventful surgery. The incidence of clinical CMO following modern cataract surgery is 1.0-2.0 % but the high number of surgeries performed worldwide makes this entity an important problem. Pre-existing conditions such as diabetes and intra-operative complications increase the risk of developing CMO post-operatively. CMO is caused by an accumulation of intra-retinal fluid in the outer plexiform and inner nuclear layers of the retina, as a result of the breakdown of the blood-retinal barrier. The mechanisms that lead to this condition are not completely understood. However, the principal hypothesis is that the surgical procedure is responsible for the release of inflammatory mediators, such as prostaglandins. Optical coherence tomography is at present an extremely useful non-invasive diagnostic tool. Guidelines for the management CMO should be focused essentially on prevention and are based on the principal pathogenetic mechanisms, including the use of anti-inflammatory drugs.
