Use of fractionated laser therapy for the treatment of androgenetic alopecia: a systematic review and meta-analysis.

Procedural management, including fractionated laser therapy, has been increasingly investigated for the management of androgenetic alopecia (AGA). However, no comprehensive resources exist detailing the efficacy of fractionated laser therapies used for the treatment of AGA. A systematic review investigating fractionated laser use for AGA was performed, separated into each distinct fractionated laser modality. A meta-analysis was performed to examine improvement in hair counts and hair shaft diameter. Fourteen studies were included for systematic review, which identified the use of erbium-glass, thulium, erbium-ytrrium:aluminum garnet (YAG), and carbon dioxide (CO2) fractionated laser for the treatment of AGA. In the meta-analysis, fractionated laser combination therapy showed significant improvement in hair shaft diameter (2.51, 95% CI 2.37-2.65, I2 = 90.54). Fractionated laser monotherapy alone significantly improved hair shaft diameter (2.28 95% CI 2.03-2.52, I2 = 91.20%). This effect was durable on subgroup analysis for both erbium-glass (2.36 95% CI 2.01-2.71, I2 = 92.05%) and thulium (1.61 95% CI 1.08-2.15, I2 = < 0.00%). There was no improvement in hair shaft count for any laser modality. Erbium-glass laser is an effective modality as either monotherapy or combination with topical/injectable therapies to improve hair shaft diameter in AGA.

Novel Vehicles For Drug Delivery in Atopic Dermatitis: A Narrative Review.

INTRODUCTION: Atopic dermatitis (AD) causes dry and itchy skin and inflammation that severely impairs the quality of life of affected children and adults. While topical glucocorticosteroid application is typically the first-line treatment of choice, steroid treatment is associated with side effects and, increasingly, patient concerns about prolonged use. Novel drugs and drug delivery vehicles are required for patients with AD. OBJECTIVES: To summarize the current literature on novel topical agents for atopic dermatitis and novel delivery vehicles. METHODS: A literature search was conducted, and a narrative review was compiled to summarize recent evidence. RESULTS: Novel topical drugs approved or in late-phase clinical trials for the treatment of AD include the Janus kinase inhibitor ruxolitinib, the phosphodiesterase-4 inhibitors crisaborole, and roflumilast, and the aryl hydrocarbon receptor activator tapinarof. While current topical drugs for AD are delivered via creams, ointments, gels, and related vehicles, novel delivery approaches such as electrospun patches, sprays, liposomes, nanoparticles, and lasers are being developed to enhance transdermal delivery, reduce side effects, and increase treatment adherence. CONCLUSIONS: Topical application of creams or ointments is currently the predominant vehicle for the delivery of atopic dermatitis drugs. In vitro studies on novel vehicles show promising results to overcome the issues associated with topical delivery. Still, these findings have to be corroborated by controlled studies with human patients in the future.

Efficacy and safety of combinational therapy using topical minoxidil and microneedling for the treatment of androgenetic alopecia: a systematic review and meta-analysis.

Androgenetic alopecia is a widespread condition that is the most common type of hair loss affecting approximately 58% and 40% of men and women by the age of 50, respectively. Patients have been known to experience severe distress due to androgenetic alopecia, including anxiety, low self-esteem, and depression. The objective of this study was to conduct a systematic review and meta-analysis to determine the efficacy of combination therapy using topical minoxidil and microneedling compared to topical minoxidil alone. This systematic review of randomized controlled trials was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The literature search was performed using Scopus, Cochrane, Embase, and the National Institutes of Health's United States National Library of Medicine from inception through January 20, 2023. Randomized controlled trials examining the efficacy of combinational therapy and monotherapy using microneedling and minoxidil on patients with clinically diagnosed androgenetic alopecia were included after screening titles, abstracts, and full texts. Two independent reviewers selected studies, extracted data, and appraised the risk of bias using the Cochrane risk of bias assessment tool. Ten randomized controlled trials, including 466 patients, were selected for this review and eight studies were ultimately included in the meta-analysis. All eight studies displayed a statistically significant increase in total hair count [standard mean difference (SMD) 1.76; 95% CI 1.26-2.26; P < 0.00001]; however, the evidence did not support a statistically significant increase in hair diameter (SMD 0.82; 95% CI - 0.01 to 1.65; P = 0.05). No scarring nor serious adverse events were reported in any of the studies. The findings of this meta-analysis strongly support the utilization of a multimodal therapeutic approach of minoxidil and microneedling for hair growth in patients with androgenetic alopecia. However, variations in factors such as rating scale measurements, microneedling methods, and areas of treatment may have resulted in confounding. Further randomized controlled, large-sample trials employing rigorous methodologies are needed to gain a more comprehensive understanding regarding treatment efficacy, namely the impact of combinational therapy on hair diameter.Clinical trial registrations This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and is registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42023391164) and the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY) database (INPLASY202310031).

Unmasking Racial Disparity in the Diagnosis and Treatment of Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic, profoundly incapacitating disease predominantly affecting the apocrine gland-rich areas of the human body. Although it affects 0.05% to 4% of the general population, there exists a significant racial disparity, with people of color, particularly Black individuals, experiencing a notably higher prevalence. Despite this disparity, the current literature lacks comprehensive analyses of HS concerning race and ethnicity, revealing a systemic blind spot in understanding and addressing the disease's racially disproportionate impacts. In this commentary, we aim to shed light on these racial disparities, focusing specifically on the stark inequities related to the timely diagnosis and subsequent dermatological care of HS in the United States. This commentary explores the racial bias in HS prevalence, severity, diagnostic delay, access to specialized care, and underrepresentation in clinical trials. By emphasizing the urgent need to address these disparities, we seek to foster an inclusive dialogue and drive proactive efforts toward achieving equitable care and research representation for all populations affected by this debilitating condition. Through this discussion, we aim to pave the way for a healthcare landscape that acknowledges and addresses the racial disparities inherent in HS, ensuring that advancements in the management of the disease cater to the needs of all populations, irrespective of their racial or ethnic background.

Cutaneous Manifestations of Malaria and Their Prognostic Windows: A Narrative Review.

Malaria is a vector-borne tropical infection caused by protozoa of the genus Plasmodium and is transmitted by the bite of an infected Anopheles mosquito. The disease is commonly characterized by fever, edema, thrombocytopenia, hypoglycemia, anemia, and myalgias; however, the infection's cutaneous presentations are not commonly emphasized and tend to be overlooked. A literature search was conducted that focused on the various skin pathologies that malaria patients have been noted to present with using case reports and currently available literature. We describe the various skin manifestations associated with malaria, such as purpura fulminans, febrile urticaria, cutaneous leishmaniasis co-infections, urticaria infectiosum, vivax-induced severe thrombocytopenia petechiae, acral skin necrosis, and reticulated erythema, and how each of these skin manifestations may provide insight into the patient's prognosis. Documentation and vigilance regarding these cutaneous manifestations must be emphasized as they may lead to better patient outcomes and a stronger understanding of the patient's underlying malaria.

Non-invasive skin measurement methods and diagnostics for vitiligo: a systematic review.

Vitiligo is a multifaceted autoimmune depigmenting disorder affecting around 0.5 to 2.0% of individuals globally. Standardizing diagnosis and therapy tracking can be arduous, as numerous clinical evaluation methods are subject to interobserver variability and may not be validated. Therefore, there is a need for diagnostic tools that are objective, dependable, and preferably non-invasive. Aims: This systematic review provides a comprehensive overview of the non-invasive objective skin measurement methods that are currently used to evaluate the diagnosis, severity, and progression of vitiligo, as well as the advantages and limitations of each technique. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was used for the systematic review. Scopus, Embase, Cochrane Library, and Web of Science databases were comprehensively searched for non-invasive imaging and biophysical skin measuring methods to diagnose, evaluate the severity of, or monitor the effects of vitiligo treatment. The risk of bias in included articles was assessed using the QUADAS-2 quality assessment scale. Results: An extensive literature search resulted in 64 studies for analysis, describing eight imaging techniques (reflectance confocal microscopy, computer-aided imaging analysis, optical coherence tomography, infrared photography, third-harmonic generation microscopy, multiphoton microscopy, ultraviolet light photography, and visible light/digital photograph), and three biophysical approaches (dermoscopy, colorimetry, spectrometry) used in diagnosing and assessing vitiligo. Pertinent information about functionality, mechanisms of action, sensitivity, and specificity was obtained for all studies, and insights into the strengths and limitations of each diagnostic technique were addressed. Methodological study quality was adequate; however, statistical analysis was not achievable because of the variety of methods evaluated and the non-standardized reporting of diagnostic accuracy results. Conclusions: The results of this systematic review can enhance clinical practice and research by providing a comprehensive overview of the spectrum of non-invasive imaging and biophysical techniques in vitiligo assessment. Studies with larger sample sizes and sound methodology are required to develop verified methods for use in future practice and research. Systematic review registration: (PROSPERO) database, (CRD42023395996).

Muscular Weakness with Calcinosis Cutis_A Case of Juvenile Dermatomyositis in a South Asian Male.

Background: Juvenile dermatomyositis (JDM) is an autoimmune connective tissue disorder characterized by an inflammation of proximal muscles of both upper and lower limbs in children below the age of 18 years. The condition mainly involves the proximal muscles and skin but extra-muscular involvement such as the gastrointestinal tract, lungs, and heart are also common. Case presentation: We present a case of a 12-year-old south Asian male who developed weakness and muscular pain in all 4 extremities at 3 years of age. The condition gradually worsened recently, and the patient developed tender ulcerated skin nodules. Power in all 4 limbs was decreased and the patient was not able to perform his routine work such as combing of hair, closing a shirt button, and walking. Laboratory investigations revealed raised total leukocyte count (TLC) and erythrocyte sedimentation rate (ESR) and biopsy of the proximal muscles and skin lesions showed focal mild necrotic infiltrate involving nonnecrotic muscle fibers and calcinosis cutis respectively. A diagnosis of JDM was made and the patient was started on immunosuppressive therapy (steroids) and diltiazem. Conclusion: JDM shares clinical features with other autoimmune, genetic, and inflammatory conditions. Proper history, thorough clinical examination, and laboratory workup is needed to rule out other masquerading conditions. This case report also highlighted the importance of diltiazem in the treatment of calcinosis cutis which is more commonly seen in patients with dermatomyositis.

Effectiveness of laser and topical tranexamic acid combination therapy in melasma: An updated systematic review and meta-analysis of randomized controlled trials.

Melasma is a chronic relapsing skin condition. Laser therapy is a new advancement in treatment. Whether the topical application of tranexamic acid (TXA) increases the efficacy of laser therapy in melasma is still under debate. With recent studies yielding different results, it was imperative to compile all the available literature systematically. This meta-analysis investigates the effectiveness of a combination therapy of laser plus TXA acid for treating melasma. PubMed/MEDLINE, Cochrane Central, Google Scholar, Scopus, and the International Clinical Trials registry were systematically searched for article retrieval. Screening per PRISMA guidelines was undertaken by two independent reviewers using the Covidance database. Melasma area of severity index (MASI)/modified MASI was used as the clinical improvement outcomes. A total of nine studies that described the combined use of topical tranexamic acid with laser therapy were included for meta-analysis. These studies employed various types of lasers along with topical TXA. The results showed that the combination of both laser therapy and topical TXA significantly decreased the MASI score (P < 0.0001). Subgroup analyses revealed that fractional CO2 laser among the laser types and monthly laser plus twice daily topical TXA were most effective in decreasing the MASI/mMASI score. The meta-analysis found that combining topical tranexamic acid and laser therapy is an effective and safer treatment option for treatment-resistant melasma. Furthermore, monthly fractional CO2 laser and daily application of topical tranexamic acid showed high effectiveness and safety.

Hidradenitis Suppurativa: Molecular Etiology, Pathophysiology, and Management-A Systematic Review.

Hidradenitis suppurativa is a chronic inflammatory skin condition that affects the hair follicles in areas of the body with apocrine glands. The condition is characterized by recurrent, painful nodules, abscesses, and draining sinuses that can lead to scarring and disfigurement. In this present study, we provide a focused evaluation of recent developments in hidradenitis suppurativa research, including novel therapeutics and promising biomarkers that may facilitate clinical diagnosis and treatment. We conducted a systematic review of controlled trials, randomized controlled trials, meta-analyses, case reports, and Cochrane Review articles in accordance with the PRISMA guidelines. The Cochrane Library, PubMed, EMBASE, and Epistemonikos databases were queried via Title/Abstract screen. Eligibility criteria included the following: (1) has a primary focus on hidradenitis suppurativa, (2) includes measurable outcomes data with robust comparators, (3) details the sample population, (4) English language, and (5) archived as full-text journal articles. A total of 42 eligible articles were selected for review. Qualitative evaluation identified numerous developments in our understanding of the disease's multiple potential etiologies, pathophysiology, and treatment options. It is important for individuals with hidradenitis suppurativa to work closely with a healthcare provider to develop a comprehensive treatment plan that addresses their individual needs and goals. To meet this objective, providers must keep current with developments in the genetic, immunological, microbiological, and environmental factors contributing to the disease's development and progression.

Diagnostic Dilemma of ANA-negative Pediatric Systemic Lupus Erythematosus in a South Asian Female.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disorder affecting multiple organs with different degrees of severity. SLE is typically diagnosed based on the presence of antinuclear antibodies (ANA) in the serum. However, seronegative SLE is rare and is diagnosed by clinicians when the patient's ANA is negative but fulfills other diagnostic criteria. Case report: We report a case of a 15-year-old South Asian female with SLE who had negative antinuclear antibodies yet displayed the typical clinical presentations of photosensitive maculopapular rash, joint pain, alopecia, anemia, and thrombocytopenia. Clinical evaluations in conjunction with lab results were used to establish a diagnosis of ANA-negative SLE. Conclusion: ANA positivity is an entry criterion for SLE; rarely, cases of ANA-negative SLE may present. A typical clinical presentation may help determine the diagnosis in such a scenario. However, still, the physician should rule out immunodeficiency and other systemic illnesses before reaching a diagnosis of ANA-negative pediatric SLE.

Blue Rubber Bleb Nevus Syndrome Presenting as Anemia, Hemorrhage, and Hemangiomas: A Rare Case Report.

Background: Blue Rubber Bleb Nevus syndrome (BRBNS) is a rare disorder, that results in congenital cutaneous hemangiomas of the skin and gastrointestinal tract. Although asymptomatic, the nevi present as soft, non-mobile, dark blue, compressible papules. Clinically it presents as iron deficiency anemia due to occult gastrointestinal bleeding. Case presentation: A 22-year-old female patient presented with complaints of shortness of breath, fatigue, and palpitation for 2 months. On examination, she had a pale effect and widespread hemangiomas on her lips, hands, and feet. Laboratory results revealed iron deficiency anemia with hemoglobin (Hb) of 2.1 gm/dl and histopathology results of the hemangioma specimen showed angiokeratomas. Based on clinical manifestations and laboratory results, the patient was diagnosed with a case of BRBNS. The patient was transfused with red cell concentrate her symptoms improved but on the first follow-up visit her Hb again dropped to 8.6 mg/dl. Conclusion: A high suspicion of BRBNS diagnosis should be considered if a patient presents with iron deficiency anemia and multiple cutaneous hemangiomas. Further screening should be done to explore internal bleeding and hemangiomas.

Splenic hematoma following acute pancreatitis, and the role of conservative management: A case report.

Key clinical message: We reported a unique case in which the patient developed splenic hematoma following acute pancreatitis, the condition responded well to conservative management without any surgical intervention. Abstract: Splenic hematoma following acute pancreatitis is a rare complication that is thought to be due to the distribution of pancreatic exudates to the spleen. We presented a case of a 44-year-old patient with acute pancreatitis who developed a splenic hematoma. He responded well to conservative management and the hematoma was resolved.

The Intersection Between Malaria Treatment and Chemoprophylaxis and Their Potential Adverse Dermatologic Manifestations: A Narrative Review.

Malaria is a life-threatening parasitic disease caused by various forms of the protozoa Plasmodium and is transmitted by the female Anopheles mosquito. The parasitic infection is endemic in 90 countries, with approximately 500 million cases reported annually and an estimated annual mortality of 1.5-2.7 million individuals. Historically, the use of antimalarial drugs has been promising for the chemoprophylaxis and treatment of malaria, mitigating the annual mortality rate. Notably, these antimalarial drugs have been associated with various adverse effects, including gastrointestinal upset and headaches. However, the adverse cutaneous manifestations these antimalarial drugs may lead to are poorly documented and understood. We aim to describe the lesser-studied adverse cutaneous pathologies of malaria treatment to better educate physicians on the proper treatment of their patients. Our narrative review describes the skin manifestations associated with specific antimalarial treatments and their associated prognoses and treatments. The cutaneous pathologies discussed include aquagenic pruritus (AP), palmoplantar exfoliation, Steven-Johnson syndrome, toxic epidermal necrolysis, cutaneous vasculitis, psoriasis, ecchymosis, and tropical lichenoid dermatitis. Further studies and vigilant documentation of the cutaneous adverse events of antimalarial drugs need to be performed and emphasized to prevent potential life-threatening adverse outcomes.

An Erythrodermic Psoriasis Flare-Up With Staphylococcus Bacteremia Secondary to COVID-19 Infection: A Case Report.

Erythrodermic psoriasis (EP) is an autoimmune condition commonly manifested as cutaneous lesions, such as well-demarcated, erythematous, scaly plaques, notably on the extensor surfaces but sometimes present on the scalp, palms, and soles. Various triggering events are known to initiate flare-ups of previously well-controlled/dormant EP. In recent literature, the association of acutely exacerbated EP after symptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been well-described. Here, we present a case of EP with increased flaking and desquamation of the skin of the whole body (most notably on the palms and soles) after three weeks of symptomatic SARS-CoV-2 infection without any other evident trigger. We aim to describe the symptoms as well as the proper management of a patient afflicted with erythrodermic psoriasis in hopes of aiding future clinicians in the prompt diagnosis and treatment of such a patient.

Snakebite Induced Cerebral Venous Sinus Thrombosis: A Case Report.

Introduction: Cerebral venous sinus thrombosis (CVST) is a rare but highly fatal neurological condition mostly caused by prothrombotic conditions like antiphospholipid syndrome, factor V Leiden, and G20210A prothrombin polymorphism. Snake bites are a rare cause of cerebral venous sinus thrombosis that must be recognized and treated promptly to improve survival. Case presentation: We present a case of a 25-year-old male who developed headaches and seizures following a Viper snake bite. The diagnosis was made based on a magnetic resonance venogram (MRV) showing transverse sinus thrombosis with sigmoid sinus stenosis. Initially, the patient was treated with antivenom and supportive treatment for disseminated intravascular coagulation (DIC). After the diagnosis of CVST, the patient was treated with rivaroxaban and levetiracetam. The patient improved within 1 week of treatment and was advised to follow up in 3 months. Conclusion: A high index of suspicion for cerebral venous sinus thrombosis is required if the patient presents with headaches, seizures, or abnormal vision following a snake bite. Early diagnosis and management can prevent further neurological damage.

Non-syndromic Intellectual Disability: An Experimental In-Depth Exploration of Inheritance Pattern, Phenotypic Presentation, and Genomic Composition.

Background Intellectual disability (ID), also termed mental retardation (MR), is a neurodevelopmental disorder characterized by an intelligence quotient (IQ) of 70 or below and a deficit in at least two behaviors associated with adaptive functioning. The condition is further classified into syndromic intellectual disability (S-ID) and non-syndromic intellectual disability (NS-ID). This study highlights the genes associated with NS-ID. Objectives A genetic study was performed on two Pakistani families to know the inheritance patterns, clinical phenotypes, and molecular genetics of affected individuals with NS-ID. Methodology Samples were collected from two families: families A and B. All affected individuals in both families were diagnosed by a neurologist. Written informed consent was taken from the affected individuals and guardians before collecting the data and sample. Family A belongs to the Swabi District of Pakistan having four affected individuals, out of whom three were male and one was female. Family B also belongs to the Swabi District of Pakistan having two affected individuals, out of whom one was male and one was female. A total of 10 candidate genes were selected and were further screened by microarray analysis. Results In family A, this analysis identified a region of 9.6 Mb on chromosome 17q11.2-q12 between the single nucleotide polymorphisms (SNPs) rs953527 and rs2680398. The region was genotyped using microsatellite markers to confirm the haplotypes in all family members. Based on the phenotype-genotype relationship, 10 possible candidate genes were selected out of more than 140 genes in this critical region of 9.6 Mb. In family B, homozygosity mapping through microarray identified four homozygous areas of affected individuals: two (27,324,822-59,122,062 and 96,423,252123,656,241) on chromosome 8, one (14,785,224-19,722,760) on chromosome 9, and one (126173647-126215644) on chromosome 11. Conclusion An autosomal recessive pattern was found in the pedigrees of both families A and B. Phenotypically affected individuals showed IQ levels below 70. Three genes, CDK5R1, OMG, and EV12A, were found on chromosome 17q11.2-q12 region of affected individuals in family A with high expression in the frontal cortex of the brain, hippocampus, and spinal cord, respectively. Other regions on chromosomes 8, 9, and 11 as evident from the affected individuals in family B can also contribute to the non-syndromic autosomal recessive intellectual disability (NS-ARID). Further research is needed to find the association of these genes with intelligence and other neuropsychiatric conditions.

Role of magnetic resonance imaging in Bouveret's syndrome: A case report with review of the literature.

Bouveret's syndrome is a rare form of gallstone ileus occurring due to obstructing gallstone into the proximal duodenum through a cholecystoduodenal fistula. We report the case of a 72-year-old female presenting with abdominal pain secondary to a large gallstone in the region of the duodenal bulb, causing the upstream gastric obstruction. Here we discuss the clinical features, imaging technologies, and surgical management of Bouveret's syndrome.

Definitive Chemoradiation With Dose Escalation for Locally Advanced Gastric Cancer: Case Studies.

Gastric cancer is a prevalent cancer with a predilection for Asian ethnicity and male patients. In early and locally advanced gastric cancer, without significant comorbidities, surgery is a part of the treatment management of this cancer. However, with concurrent comorbidities, surgery may not be recommended and alternative treatment options such as palliative chemotherapy and/or radiation and definitive chemoradiation can be considered to reduce morbidity. We present three cases of gastric cancer where definitive chemoradiation with dose escalation was utilized due to underlying comorbidities and poor performance status. The treatment was generally well tolerated by patients and resulted in substantial reduction in gastric mass size in two patients with median overall survival of 10 months.
