RESUMEN
Atopic dermatitis (AD) is a prevalent, chronic inflammatory skin condition characterized by pruritus, erythema, and impaired skin barrier function. AD management presents significant challenges due to its complex pathophysiology involving immune dysregulation and genetic predispositions. While traditional therapies, such as topical corticosteroids and emollients, remain foundational, their limitations have spurred the development of novel pharmacological approaches. This comprehensive review explores current pharmacological trends in the management of AD, focusing on emerging therapies that target specific immunological pathways. Biologic agents, including monoclonal antibodies against interleukin (IL)-4, IL-13, and IL-31 receptors, offer targeted mechanisms to modulate immune responses implicated in AD pathogenesis. Janus kinase (JAK) and phosphodiesterase-4 (PDE-4) inhibitors represent another class of promising therapies, providing alternatives for patients resistant to conventional treatments. The review synthesizes evidence from clinical trials and studies to evaluate these pharmacological agents' efficacy and safety profiles. Considerations for personalized medicine approaches, including biomarkers for treatment response prediction and genotype-based therapies, are discussed to highlight the potential for tailored treatment strategies in AD management. In conclusion, this review underscores the evolving landscape of pharmacological interventions for AD, emphasizing the need for continued research to address unmet clinical needs and optimize patient outcomes. By delineating current advancements and future directions, this review aims to inform clinical practice and guide future research endeavours in dermatology.
RESUMEN
Scrofuloderma, a manifestation of cutaneous tuberculosis, is a less common but clinically significant form of mycobacterial infection. It typically arises from the contiguous spread of Mycobacterium tuberculosis from an underlying infected lymph node or osseous structure to the adjacent skin. The condition manifests predominantly as chronic, granulomatous inflammation that leads to skin ulcers and abscesses. Despite its rarity, scrofuloderma presents substantial diagnostic challenges, primarily due to its nonspecific clinical presentation, which may mimic other dermatological conditions. This case report delineates the clinical journey of a patient with scrofuloderma who was attended to in a tertiary care setting. It emphasizes the diagnostic complexities encountered, underscored by a comprehensive discussion of the investigative modalities used to establish the diagnosis. This report elaborates on the therapeutic regimen taken, showcasing the effectiveness of a customized antituberculosis treatment plan.
RESUMEN
Oculocardiac reflex (OCR), presenting as bradycardia and asystole, is a potential intraoperative complication that may occur during maxillofacial trauma surgery. Bradycardia is the most common symptom of this phenomenon. Surgeons should be aware of its long-term effects, such as arrhythmias and even cardiac arrest. We report the case of a 40-year-old male patient with a fracture of the floor of the orbit. During a surgical exploration of the orbital floor, the patient exhibited sudden symptoms of OCR. It was managed by withholding the surgery and administering atropine. The article also highlights the mechanism, types, incidence, and management of OCR in patients with maxillofacial trauma.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
It is of interest to compare 0.2% chlorhexidine gel, 0.2% chlorhexidine chip, minocycline microspheres and slow-release doxycycline gel and tetracycline fibers as drug delivery systems in the management of peri-implantitis. The study comprised of 105 Indian participants who had a minimum of one dental implant with a probing depth of 4 mm, along with exudate and/or bleeding upon probing along with the presence of potentially harmful germs. The use of minocycline microspheres and 0.2% chlorhexidine gel resulted in significant improvements in probing depths at 1 month, 3 months and 6 months and all treatments showed decline in the indicator bacteria. Thus, minocycline microspheres and 0.2% chlorhexidine gel is useful as an adjuvant for mechanical debridement in management of peri-implantitis.
