Dermoscopic Features and Their Diagnostic Values Among Common Inflammatory and Infectious Dermatoses: A Cross-Sectional Study.

Background: Dermoscopy is a non-invasive tool widely used to improve the diagnostic accuracy of general dermatological conditions.

Objective: To determine the dermoscopic features and their diagnostic value in distinguishing common inflammatory and infectious dermatoses.

Materials And Methods: A cross-sectional study was conducted on patients clinically diagnosed with common inflammatory or infectious skin diseases.

A comparative study of pain perception during the microfocused ultrasound procedure between topical anesthesia and combined topical anesthesia with forced air cooling.

Background: The experience of pain during microfocused ultrasound with visualization (MFU-V) treatment is common and crucial for dictating patient satisfaction and retention.

Objective: To compare the pain perception during the MFU-V procedure between two pain reduction methods (topical anesthesia alone versus combined topical anesthesia with forced air cooling).

Materials And Methods: This was a prospective, single-blinded, randomized controlled trial.

Variation of Hair Follicle Counts among Different Scalp Areas: A Quantitative Histopathological Study.

Introduction: Scalp biopsy is a standard method for the definitive diagnosis of alopecia. The hair count parameters of each scalp area remain unclear. This study aimed to determine hair count values at different scalp locations from histopathology and to establish reference values for each part of the scalp.

The study of hair follicle counts from scalp histopathology in the Thai population.

Background: The horizontal section of a scalp specimen offers an advantage over a vertical section by providing quantitative information. The reference data for hair counts in Asians, including Thais, are inconclusive. We aimed to determine the normal values of hair counts in scalp biopsy specimens in the Thai population.

Nonscarring alopecia in systemic lupus erythematosus: A cross-sectional study with trichoscopic, histopathologic, and immunopathologic analyses.

Background: Nonscarring alopecia in systemic lupus erythematosus (SLE) is widely recognized, but reports on its clinical, trichoscopic, histopathologic, and direct immunofluorescence (DIF) features are still limited.

Objective: To summarize the different clinical patterns, trichoscopic, histopathologic, and DIF features of nonscarring alopecia in SLE and to prove its association with disease activity.

Methods: Patients with SLE with and without nonscarring alopecia had full physical/trichoscopic examination and scalp biopsy.

Disseminated extrapulmonary Legionella pneumophila infection presenting with panniculitis: case report and literature review.

Background: Legionellosis is a well-known cause of pneumonia. Primary cutaneous and subcutaneous infection caused by Legionella pneumophila is rare and the diagnosis is challenging.

Case Presentation: A 38-year-old Thai woman with systemic lupus erythematosus and myasthenia gravis treated with prednisolone and azathioprine presented to our hospital with low-grade fever, diarrhea, and indurated skin lesions on both thighs.

The study of histological changes of the arterial vascular structure after hyaluronidase exposure.

Background: Hyaluronic acid (HA) filler injection is commonly used for soft tissue augmentation. Uncommon but serious complication from filler injection is vascular occlusion. Hyaluronidase enzyme can be used to dissolve HA filler.

Clinicopathological Features and Prognostic Factors of Malignant Melanoma: A Retrospective Analysis of Thai Patients in Ramathibodi Hospital.

Objective: To present the clinicopathological characteristics of cutaneous melanoma in Thai patients and to define the possible clinicopathological prognostic factors.

Material And Method: A retrospective study of primary cutaneous melanoma in Thai patients in Ramathibodi Hospital between January 2007 and December 2012 was conducted. All medical records and skin biopsies were reviewed for demographic data and histopathologicalfeatures.

Double check up of malignancy biopsy specimens for patient safety.

Background: The diagnostic of malignancy in biopsy specimens is very important because it guides to selected treatment option and prognostic prediction. However biopsy specimens usually have small pieces leading to variations of the interpretation by anatomical pathologists.

Objective: To detect and correct the errors or the significant discrepancies in the diagnosis of biopsy specimens before sign-out and to determine the frequency of anatomic pathology significant discrepancies.
