Shedding Light on Acne Scars: A Comprehensive Review of CO2 vs. Erbium-Doped Yttrium Aluminium Garnet (Er:YAG) Laser Therapy.

Acne scars pose a significant cosmetic concern and can have a profound impact on individuals' self-esteem and quality of life. Laser therapy has emerged as a promising treatment modality for improving the appearance of acne scars by promoting collagen remodeling and tissue regeneration. This comprehensive review compares two commonly used laser modalities, CO2 and erbium-doped yttrium aluminum garnet (Er:YAG), focusing on their mechanisms of action, efficacy, safety profiles, and patient outcomes. While CO2 lasers offer deeper tissue penetration and the potential for more significant improvement in severe acne scars, Er:YAG lasers provide a gentler approach with a lower risk of post-inflammatory hyperpigmentation. Recommendations for clinical practice include tailoring treatment approaches to individual patient characteristics, educating patients about treatment expectations and post-treatment care, considering combination therapies for enhanced outcomes, and implementing regular follow-up care. Areas for further research include long-term outcome studies, investigation of laser therapy in ethnically diverse populations, exploration of combination therapies, and evaluation of emerging laser technologies. This review aims to provide clinicians and patients with valuable insights to inform treatment decisions and optimize outcomes in managing acne scars.

Drug-Induced Pseudoporphyria: A Case Report.

Pseudoporphyria is an uncommon dermatosis resembling porphyria cutanea tarda (PCT). The exclusion of true porphyria, especially PCT, is critically essential for diagnosing pseudoporphyria. It has an unknown underlying pathophysiology with a normal or near-normal porphyrin profile. Pseudoporphyria has been associated with chronic renal failure and hemodialysis, medications, and tanning beds. In drug-induced pseudoporphyria cases, eliminating the suspected photosensitizing drug improves the disease typically within weeks to months (on average eight weeks). In genetically predisposed individuals, phototoxic metabolites may trigger the development of skin fragility, bullae, milia, and scarring on the dorsum of the hands and other sun-exposed areas. Wearing a broad-spectrum sunscreen and maintaining strict ultraviolet protection is essential in cases of pseudoporphyria. We report the case of a 20-year-old male who presented to us with complaints of photosensitivity and multiple erosions with irregular scars over photo-exposed areas involving the dorsum of the hands and face predominantly. The patient was evaluated further to determine the underlying cause. A wood's lamp examination of the urine was done, which did not show fluorescence. Based on clinical and laboratory findings, the diagnosis of pseudoporphyria was made, and the patient was started on the oral antimalarial agent hydroxychloroquine sulfate with strict sun protection.

A Comprehensive Review on the Efficacy of Anti-CD20 Therapies in Pemphigus Treatment.

Pemphigus, an autoimmune blistering disorder, poses significant therapeutic challenges due to dysregulated B cells and the involvement of CD20. This review assesses the efficacy of anti-CD20 therapies, including rituximab, ofatumumab, ocrelizumab, and obinutuzumab, in pemphigus treatment. Mechanisms of action, clinical studies, and safety profiles were analyzed, revealing diverse impacts on disease severity. B cell depletion emerged as a pivotal factor, disrupting the autoimmune process and reducing pathogenic antibodies. Varied efficacy and safety profiles among agents underscore the need for personalized treatment strategies guided by biomarkers. Challenges such as resistance and long-term safety concerns necessitate continued research and vigilance. In clinical practice, insights from this review inform nuanced, tailored approaches for improved pemphigus management. The dynamic landscape of emerging therapies and personalized medicine emphasizes the need for ongoing research and strategic clinical decision-making. This review is a foundation for future investigations, providing insights for clinicians and researchers in optimizing pemphigus treatment.

Elephantiasis Nostras Verrucosa in a Patient With Lymphedema Tarda.

This case report presents a rare and complex clinical scenario of a 42-year-old male diagnosed with elephantiasis nostras verrucosa in the context of lymphedema tarda. The patient's seven-year history of insidious and progressively worsening swelling over the left lower limb, inguino-scrotal region, and left upper limb posed diagnostic challenges, leading to a multidisciplinary evaluation. Clinical examination, imaging studies, and laboratory investigations were integral in confirming the diagnosis. The manifestation of elephantiasis nostras verrucosa, characterized by extensive hyperkeratosis, added a unique dimension to the clinical presentation. A comprehensive treatment approach involving nutritional supplementation and pharmacological interventions was initiated to address the multifaceted aspects of lymphatic dysfunction. This case underscores the importance of a collaborative and holistic approach to managing complex lymphatic disorders, contributing valuable insights to the medical literature.

Painful Limb Ulcers: A Case Report on Ulcerative Discoid Lupus Erythematosus.

Lupus erythematosus is an autoimmune disorder with varied clinical features. Discoid Lupus Erythematosus (DLE) presents as erythematous, raised plaques. The patients might present with photosensitivity, arthralgia, and nail changes. However, dermoscopy, clinical features, and laboratory markers like high titers of Antinuclear antibodies (ANA) help in clenching the diagnosis. We report a patient in her mid-60s presented with non-healing ulcers oozing pus discharge associated with pain and joint stiffness. Thus, a series of investigations, treatment modifications, and the healing progression of the lesions highlight the importance of retrospective diagnosis.

Systemic Sclerosis Presenting With Frank Exhibition of Mizutani's Sign.

Systemic sclerosis is an autoimmune connective tissue disease (AICTD) known for its hallmark feature of fibrosis affecting the skin, blood vessels, and viscera. The maintenance of the extracellular matrix (ECM) involves fibroblasts and other cells, which play a vital role in the degradation and replacement of damaged proteins such as collagens with new ones. The continuous stimulation of fibroblasts results in the overproduction of extracellular matrix proteins, leading to the progression of fibrosis. Although the exact etiology of scleroderma is not clear, the onset of the condition has been attributed to genetic and environmental factors. Excessive collagen buildup in the dermis is the telltale sign of the disease. Clinicians face significant challenges in managing systemic sclerosis. Management is based on reducing or eliminating complaints to improve organ function, and frequently, multidisciplinary involvement is required. The aim of this case report is to emphasize the importance of the recognition of Mizutani's sign, which makes it prudent to rule out the presence of systemic sclerosis.

Adalimumab in the Treatment of Recalcitrant Livedoid Vasculopathy.

Livedoid vasculopathy is a rare condition affecting the cutaneous vasculature. Patients typically develop bilateral lower limb ulcers that tend to recur and do not heal. Edema, discomfort, and itching are linked to ulcers. The patient's quality of life is negatively impacted by this. Atrophie blanche, a stellate, porcelain-white scar, is typically left behind once these ulcers heal. Livedoid vasculitis, livedo reticularis with ulcerations, atrophie blanche, segmental hyalinizing vasculitis, and painful purpuric ulcers with a reticular pattern on the lower limbs are some of the terminologies used to describe livedoid vasculopathy. This condition has been treated using various techniques, including intravenous immunoglobulins, steroids, anticoagulants, antibiotics, immunosuppressive drugs, and antiplatelets. Here, we report the case of a 24-year-old male who presented with a red-colored, painful, and itchy lesion over his right calf for one year. He had recurring lesions over his right foot for the past 18 years. He had received multiple treatment courses over 18 years but had no relief. He was treated with eight doses of adalimumab injection (40 mg/0.8 mL) administered subcutaneously at an interval of 15 days. He had near-complete healing of the ulcer and complete remission of symptoms.

A Case Report on Senear-Usher Syndrome.

Pemphigus erythematosus is an uncommon autoimmune bullous skin disorder with clinical, histological, and serological characteristics that overlap with lupus erythematosus and pemphigus foliaceus. The autoantigens are desmoglein 3, desmoglein 1, and desmosomal adhesion proteins in keratinocytes. When these bonds are disrupted, it causes acantholysis of keratinocytes, leading to the fluid collection between layers. Hence, the patient will present clinically with small flaccid bullae with crusting and scaling, mainly on the seborrheic areas. We report the case of a 21-year-old female presenting to us with multiple hyperkeratotic plaques, mainly on the seborrheic areas, including the face, chest, and elbows. The patient was evaluated further, and based on clinical and laboratory investigations, the diagnosis of pemphigus erythematosus associated with anti-double-stranded deoxyribonucleic acid (anti-dSDNA) and anti-nuclear antibody (ANA) positivity was made. The patient was then managed using immunosuppressant therapy, and the entire course has been detailed in this case report.
