Ambulatory and Primary Care Articles

OBJECTIVE: Although agitation is a common neuropsychiatric symptom in Alzheimer's dementia, it can be challenging to recognize and diagnose. Caregivers of individuals with Alzheimer's dementia are often the first to encounter agitation behaviors but may struggle to recognize and communicate symptoms to healthcare professionals (HCPs). Here, we describe the development and evaluation of the Agitation in Alzheimer's Screener for Caregivers (AASC), a practical screening tool to identify agitation symptoms and facilitate caregiver-HCP communication.

METHODS: The AASC was developed based on the International Psychogeriatric Association (IPA) criteria for agitation in cognitive disorders, input from multidisciplinary experts, and qualitative interviews with caregivers …

Linden 305 Llc V. Miller

All Decisions

In this licensee holdover, the tenant moved to disqualify the landlord's counsel, arguing a conflict of interest because one of the firm's attorneys previously represented the tenant in a substantially related prior proceeding. The court found that a presumption of disqualification arose, but the landlord rebutted it by demonstrating that the attorney lived out of state, was not involved in the current proceeding, did not possess material information, and the firm had established an ethical wall. The court denied the tenant's motion but prohibited the firm from discussing the case with the attorney in question.

Association Between Vitamin D And Cholesterol In Post-Acne Hypertrophic Scars And Keloids: A Cross-Sectional Study, Yuli Kurniawati, Yulia Farida Yahya, Sarah Diba, Rina Novriani, Hasbiallah Yusuf, Ekta Martgaredta

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Post-acne hypertrophic scars and keloids result from abnormal wound healing within the pilosebaceous unit. Ruptured microcomedones create wounds that can lead to prolonged inflammation, increased collagen synthesis, and fibrinolysis inhibition, resulting in elevated scar tissue in acne lesions. Vitamin D deficiency can lead to prolonged inflammation and damage to dermal collagen. High total cholesterol levels can lead to excessive sebum production, exacerbating inflammation and fibrosis. This study aimed to determine the association between serum vitamin D and total cholesterol levels with scar severity in patients with post-acne hypertrophic scars and keloids.

Methods: This analytical cross-sectional study was conducted at …

Extensive Superficial Dermatomycosis Caused By Cladophialophora Sp., A Deep Mycosis Pathogen: A Case Report, Nikko Vanda Limantara, Agnes Sri Siswati, Flandiana Yogianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Superficial dermatomycosis, predominantly caused by dermatophytes, affects approximately 20–25% of the global population. However, non-dermatophytic fungi, such as Cladophialophora species (sp.), can also cause similar cutaneous infections. Although less common, these organisms are particularly concerning in immunocompromised individuals.

Case Illustration: A 66-year-old immunocompromised male presented with widespread pruritic and erythematous patches, initially misdiagnosed as tinea corporis. Despite receiving standard antifungal therapy, his condition persisted. Further investigation through fungal culture identified Cladophialophora sp., which was resistant to common antifungal agents such as fluconazole, itraconazole, and ketoconazole. However, the fungus was sensitive to terbinafine, which has …

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Melasma is a common acquired pigmentary condition presenting as dark macules or patches on sun-exposed areas of the face. Conventional treatments rely on topical bleaching agents and sun protection, while additional adjuvant options such as chemical peels, dermabrasion, and laser procedures are often applied. However, recurrence is frequent, and overall therapeutic success remains modest, significantly affecting patient quality of life. Recently, tranexamic acid (TXA) has gained attention as a novel therapeutic approach.
