Natural Treatment Options for Nail Disorders.

The growing demand for natural treatments has raised concerns among clinicians due to limited scientific evidence supporting their use. This review article addresses the issue by assisting dermatologists and general practitioners in recommending natural treatments for the following common nail disorders: nail brittleness, onychomycosis, periungual verrucae, paronychia, chloronychia, nail psoriasis, nail lichen planus, onychocryptosis, onycholysis, and congenital malalignment of the great toenail. One limitation is the scarcity of existing reviews on natural treatment options for nail disorders in the literature. Through a comprehensive review of existing literature, this article consolidates the available evidence on natural treatment options for these conditions. Although some natural treatments for nail disorders are supported by scientific evidence, the indiscriminate use of such remedies may lead to severe poisoning and health problems. Given the widespread and increasing use of natural treatments, clinicians play a pivotal role in educating patients about evidence-based remedies and debunking misleading claims. By doing so, clinicians can enhance patient safety and improve treatment outcomes. It is essential for healthcare professionals to be well-informed and equipped with the knowledge to differentiate between effective natural treatments and unverified claims, ensuring that patients receive appropriate care.

Acne and Pregnancy: A Clinical Review and Practice Pearls.

Acne vulgaris is a common condition that routinely affects females of childbearing age. Taking into consideration the reproductive journey of women when treating acne is of paramount importance given the safety concerns to both the mother and the fetus associated with certain medications. Therefore, careful consideration of therapeutic choices during pregnancy is crucial. Herein, we summarize the safety of acne treatments during pregnancy and offer practical clinical pearls for routine dermatology practice.

Safety of dermatologic medications in pregnancy and lactation: An Update - Part I: Pregnancy.

The breadth of therapeutic options for the management of dermatologic skin conditions continues to expand rapidly as exemplified by biologics and small molecule drug development. While dermatologists and healthcare providers are aware of the underlying mechanisms and indications for these therapeutics, there is a recognized practice gap due to an incomplete understanding of the safety of these medications in women of childbearing age during the prepartum, antepartum and postpartum phases. Although a two-part continuing medical education review was published regarding the prescribing practices and safety profiles of these new therapeutics in women of childbearing age while pregnant or lactating in 20141,2, many new medications have been approved since then. Herein, we will update the safety of dermatologic therapies during pregnancy and Part II will review the safety of medications during lactation.

Safety of dermatologic medications in pregnancy and lactation: An Update - Part II: Lactation.

Multiple recently approved medications have been added to our treatment armamentarium for various dermatologic conditions. Herein, we have reviewed the literature, consolidated available safety data, and offered recommendations based upon available evidence as a reference guide for clinicians treating patients for dermatologic conditions during lactation.

Biospecimen Repositories in Low- and Middle-Income Countries: Insights From an American University of Beirut and Memorial Sloan Kettering Collaboration.

PURPOSE: Biobanking helps source tissue and blood for studying cancer genomics. Access to biorepository resources in low- and middle-income countries is lacking. Memorial Sloan Kettering Cancer Center (MSK) and the American University of Beirut (AUB) established a joint tissue biorepository at AUB in Beirut, Lebanon. The undertaking encountered key challenges that were unanticipated. MATERIALS AND METHODS: Patients age 18 years or older were eligible for enrollment at AUB. After consent, biospecimens were obtained at the time of routine diagnostic and/or therapeutic interventions. Both normal and abnormal tissue and solid and/or liquid specimens were collected from varied body sites. Early on, declining consent was frequently observed, and this was highlighted for investigation to understand potential participants reasoning. RESULTS: Of 850 patients approached, 704 (70.8%) elected to consent and 293 (29.5%) declined participation. The number of declined consents led to an amendment permitting the documentation of reasons for same. Of 100 potential participants who declined to consent and to whom outreach was undertaken, 63% indicated lack of research awareness and 27% deferral to their primary physician or family member. A financial gain for AUB was cited as concern by 5%, cultural boundaries in 4%, and 1% expressed concern about confidentiality. Of the patients who elected to consent, 682 biospecimens were procured. CONCLUSION: The AUB-MSK biospecimen repository has provided a unique resource for interrogation. Patient participation rate was high, and analyses of those who elected not to consent (29%) provide important insights into educational need and the local and cultural awareness and norms.

Review of Superficial Cryotherapy for the Treatment of Alopecia Areata.

Cryotherapy has recently been examined as a potential treatment for alopecia areata (AA). AA is classically managed with intralesional or systemic steroids but relapse rates among those with longstanding disease are high. This narrative review serves to describe the existing studies evaluating cryotherapy for the treatment of AA and examine studies comparing cryotherapy with intralesional steroid injection for the treatment of AA. A review of the literature from 1990 to 2022 was conducted looking for keywords such as “alopecia areata” and “cryotherapy". A total of 8 studies were identified. Three studies assessed the efficacy of liquid nitrogen cryotherapy for the treatment of AA and found approximately 60% of patients responded to treatment and achieved hair regrowth. Three studies compared cryotherapy with intralesional corticosteroid injection, and 2 studies compared cryotherapy with topical corticosteroid therapy. There was no statistically significant difference in efficacy, but there is some evidence to suggest that relapse rates were lower in the cryotherapy group. Treatment protocols differed between studies regarding the number of cycles used for cryotherapy, dosage of intralesional steroids, and patient populations used. Some studies examined cases of recalcitrant AA while other studies examined all cases of AA. More research with larger sample sizes and with similar experimental procedures is necessary to assess the clinical efficacy of cryotherapy.Kaiser M, Issa N, Yaghi M, et al.

Beard Alopecia: An Updated and Comprehensive Review of Etiologies, Presentation and Treatment.

Facial hair is an important social and psychologic aspect of clinical appearance for men. The purpose of this review is to provide a comprehensive overview of the causes of alopecia of the beard including the prevalence, pathophysiology, clinical presentation, and treatment. In this review, we highlight more common causes of beard alopecia including alopecia areata and pseudofolliculitis barbae, infectious causes such as tinea barbae and herpes simplex folliculitis, and rare causes including dermatopathia pigmentosa reticularis and frontal fibrosing alopecia. This review serves as an important resource for clinicians when faced with patients suffering from beard alopecia.

Geographic Origin may Affect Outcomes for Hispanic Patients with Non-Small Cell Lung Cancer in the United States.

BACKGROUND: Social determinants of health thoroughly explored in the literature include insurance status, race, and ethnicity. There are over 50 million self-identifying Hispanics in the United States. This, however, represents a heterogeneous population. We used a national registry to investigate for significant differences in outcomes of Hispanic patients with non-small cell lung cancer (NSCLC) in the Unites states, by geographic region of origin. MATERIALS AND METHODS: We identified a cohort of Hispanic patients in the Unites states with NSCLC for which region of origin was documented within the 2004 to 2016 National Cancer Database (NCDB) registry. This included patients from Cuba, Puerto Rico, Mexico, South and Central America, and the Dominican Republic. We performed multivariate logistic regression modeling to determine whether origin was a significant predictor of cancer staging at diagnosis, adjusting for age, sex, histology, grade, insurance status, and facility type. Race was not included due to a nonsignificant association with stage at diagnosis at the bivariate level in this cohort. Subsequently, we used Kaplan-Meier modeling to identify whether overall survival (OS) of Hispanic patients differed by origin. RESULTS: A total of 12,557 Hispanic patients with NSCLC were included in this analysis. The breakdown by origin was as follows: n = 2071 (16.5%) Cuban, n = 2360 (18.8%) Puerto Rican, n = 4950 (39.4%) Mexican, n = 2329 (18.5%) from South or Central America, and n = 847 (6.7%) from the Dominican Republic. After controlling for age, sex, histology, grade, insurance status and treating facility type, we found that geographic origin was a significant predictor of advanced stage at diagnosis (P = .015). Compared to Cubans, patients of Puerto Rican origin were less likely to present with advanced disease (68.4% vs. 71.9%; OR: 0.82; 95%CI: 0.69-0.98; P = .026). We also identified a significant (log-rank P-value<.001) difference in OS by geographic origin, even at early-stages of diagnosis. Dominican patients with NSCLC exhibited the highest 5-year OS rate (63.3%), followed by patients from South/Central America (59.7%), Puerto Rico (52.3%), Mexico (45.9%), and Cuba (43.8%). CONCLUSION: This study showed that for Hispanic individuals living in the Unites states, region/country of origin is significantly associated with outcomes, even after accounting for other known determinants of health. We suggest that region of origin should be studied further as a potential determinant of outcomes in patients with cancer.

Social disparities in pain management provision in stage IV lung cancer: A national registry analysis.

A strong association exists between pain and lung cancer (LC). Focusing on the disparities in pain referral in LC patients, we are aiming to characterize the prevalence and patterns of referrals to pain management (PM) in Stage IV non-small-cell LC (NSLC) and small-cell LC (SCLC). We sampled the National Cancer Database for de novo stage IV LC (2004-2016). We analyzed trends of pain referral using the Cochran-Armitage test. Chi-squared statistics were used to identify the sociodemographic and clinico-pathologic determinants of referral to PM, and significant variables (P < .05) were included in one multivariable regression model predicting the likelihood of pain referral. A total N = 17,620 (3.1%) of NSLC and N = 4305 (2.9%) SCLC patients were referred to PM. A significant increase in referrals was observed between 2004 and 2016 (NSLC: 1.7%-4.1%, P < .001; SCLC: 1.6%-4.2%, P < .001). Patient and disease factors played a significant role in likelihood of referral in both groups. Demographic factors such as gender, age, and facility type played a role in the likelihood of pain referrals, highlighting the gap and need for multidisciplinary PM in patients with LC. Despite an increase in the proportion of referrals to PM issued for terminal stage LC, the overall proportion remains low. To ensure better of quality of life for patients, oncologists need to be made aware of existent disparities and implicit biases.

Hidradenitis Suppurativa: Surgery, Lasers, and Emerging Techniques.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that is characterized by painful nodules, abscesses and tunnels in skin folds. Current management of HS often requires a multidisciplinary approach, including medical, procedural, surgical, and psychosocial intervention. Here we review surgical techniques for the treatment of HS. While many surgical options are available for patients with HS, it is imperative that surgical planning focuses on medical optimization, patient risk factors, disease severity, and patient preferences to achieve the best outcomes.

Efficacy of chemotherapy in patients with HR+/HER2-Invasive lobular breast cancer.

INTRODUCTION: Invasive Lobular Breast Cancer (ILC) harbors unique clinicopathologic features. Data on optimal treatment modalities focusing on ILC remain scarce. We aim to investigate the benefit of chemotherapy in early-stage hormone receptor-positive (HR+) and human epidermal growth factor receptor-2 negative (HER2-) ILC. METHODS: Female patients with early HR+/HER2- ILC (stages I-III) who underwent surgery were selected from the National Cancer Database (2010-2016) and grouped into four treatment cohorts: surgery only(S), chemotherapy alone (CT), endocrine therapy alone (ET), and combined chemotherapy followed by endocrine therapy (CET). Descriptive and bi-variate statistics summarized baseline characteristics and compared them across cohorts. A secondary analysis accounting for OncotypeDX (ODX) information was performed, stratifying for low (<26) and high (≥26) ODX. Kaplan-Meier (KM) and Cox proportional hazard models evaluated the relationship between treatment modality and overall survival (OS), stratifying for ODX scoring. RESULTS: N = 15,271 patients were included. The CET cohort (29.8%) was more likely to be younger and have no co-morbidities, advanced tumor stage or high ODX score (≥26). No significant difference in OS comparing ET to CET (HR:1.08, 95%CI:0.93-1.26, p = 0.31) was observed, adjusting for confounders. N = 5,561 patients had ODX results available. No significant difference in 5-year OS was observed comparing the ET to CET cohorts, both in patients an ODX score <26 (HR:1.10; 95%CI:0.69-1.76, p = 0.69) and ODX score ≥26 (HR:1.18; 95%CI:0.51-2.75, p = 0.69). CONCLUSION: Chemotherapy demonstrated no added survival benefit in HR+/HER2- ILC, even in tumors with ODX ≥26. Prospective trials identifying potential subgroups of patients with ILC who could benefit from chemotherapy are needed.

The Gut Microbiome and Alzheimer's Disease: A Growing Relationship.

Evidence that the gut microbiota plays a key role in the pathogenesis of Alzheimer's disease is already un-ravelling. The microbiota-gut-brain axis is a bidirectional communication system that is not fully understood but includes neural, immune, endocrine, and metabolic pathways. The progression of Alzheimer's disease is supported by mechanisms related to the imbalance in the gut microbiota and the development of amyloid plaques in the brain, which are at the origin of Alzheimer's disease. Alterations in the composition of the gut microbiome led to dysregulation in the pathways governing this system. This leads to neurodegeneration through neuroinflammation and neurotransmitter dysregulation. Neurodegeneration and disruption of the blood-brain barrier are frontiers at the origin of Alzheimer's disease. Furthermore, bacteria populating the gut microbiota can secrete large amounts of amyloid proteins and lipopolysaccharides, which modulate signaling pathways and alter the production of proinflammatory cytokines associated with the pathogenesis of Alz-heimer's disease. Importantly, through molecular mimicry, bacterial amyloids may elicit cross-seeding of misfolding and induce microglial priming at different levels of the brain-gut-microbiota axis. The potential mechanisms of amyloid spreading include neuron-to-neuron or distal neuron spreading, direct blood-brain barrier crossing, or via other cells such as astrocytes, fibroblasts, microglia, and immune system cells. Gut microbiota metabolites, including short-chain fatty acids, pro-inflammatory factors, and neurotransmitters may also affect AD pathogenesis and associated cognitive decline. The purpose of this review is to summarize and discuss the current findings that may elucidate the role of gut microbiota in the development of Alzheimer's disease. Understanding the underlying mechanisms may provide new insights into novel therapeutic strategies for Alzheimer's disease, such as probiotics and targeted oligosaccharides.

Medullary carcinoma of the colon: A comprehensive analysis of the National Cancer Database.

PURPOSE: Medullary carcinomas (MC) of the colon are uncommon tumors. In this study, we analyzed demographic and disease characteristics as well as survival outcomes of MC versus undifferentiated (UDA) and poorly differentiated (PDA) adenocarcinomas (AC) of the colon. MATERIALS AND METHODS: The National Cancer Database (2004-2018) was utilized to identify patients with colon cancer. Patient demographics (including age, gender, race), disease characteristics (including grade, TNM stage, carcinoembryonic levels, perineural and lymphovascular invasion, lymph node status, microsatellite stability, KRAS mutation, and primary tumor site), and facility type and location were evaluated. Chi-square tests were used to compare descriptive data. Cox Regression and Kaplan Meier analyses were used to analyze survival characteristics. RESULTS: 1,041,753 patients with colon cancer were identified of whom 2709 patients had MC and 897,902 had AC (136,597 PDA and 18,042 UDA). MC was seen in older patients (mean age 74 ± 13 years) and women (72.5% vs. 27.5% males). Most MCs were poorly differentiated (63.3%), and 82.4% of patients with MC had microsatellite instability. Fewer patients with MC had perineural invasion (15.6% vs. 22.0% in PDA and 22.4% in UDA, p < 0.001) and positive lymph nodes (38.4% versus 59.9% with PDA and 59.7% with UDA, p < 0.0001). MC diagnosis increased by year (Cochran-Armitage trend test, p < 0.0001). Kaplan Meir analysis revealed a better prognosis for patients with MC when compared to PDA or UDA (p < 0.001). CONCLUSION: Given the rarity, pathologists should maintain a high suspicion for MC when encountering poorly differentiated or undifferentiated right-sided colon cancer with associated MSI-H.

Choledochal anomalies in adults: A 20-year single-center retrospective cohort experience in the Middle East.

BACKGROUND AND STUDY AIMS: Choledochal cysts are rare congenital cystic dilatations of the bile ducts that occur in fewer than 1% of individuals. The disease is common in East Asia, and most of the literature concerns those populations, but some data about Western populations have been published recently. Long-term reports about the disease in Middle Eastern populations, however, are currently lacking. We report a single-center 20-year experience in diagnosing and managing choledochal anomalies. PATIENTS AND METHODS: Participants were adult patients in whom choledochal cysts were diagnosed over a 20-year (2000-2019) period at a single tertiary academic care center. Clinical data, including radiologic imaging findings, were retrieved from the patients' medical records. To describe the baseline characteristics of the population, we calculated descriptive statistics. RESULTS: Choledochal anomalies were diagnosed in 19 adult patients, whose median age was 30 years (interquartile range [IQR], 23-67 years). Of the choledochal cysts 13 (68.4%) were classified as Todani type I, 4 (21.1%) as Todani type IV, and 3 (15.8%) as Todani type V (Caroli's disease). No patient had underlying chronic liver disease, and liver synthetic function was preserved in all. Eighteen patients (94.7%) underwent surgery: cyst excision with Roux-en-Y hepaticojejunostomy in 17 and liver transplantation in 1. All 18 survived surgery, and the median postoperative hospital stay was 11 days (IQR, 5-34 days). All 18 were alive 90 days after surgery, and the median follow-up period was 40 months (IQR, 12-140 months). Seven patients (36.8%) developed postoperative surgical complications; 2 patients required rehospitalization, and 1 required reoperation. CONCLUSION: This description of adults with choledochal cysts is the latest long-term report about this disease in the Middle East. In our 20-year experience, the disease characteristics in our patients were moderately consistent with those described previously.

Merkel cell carcinoma: Epidemiology, disease presentation, and current clinical practice outcomes.

Using the National Cancer Database, we introduce the findings of a retrospective investigation of the largest cohort of cases with Merkel cell carcinoma (N = 20,829). A decreasing proportion of stage I (P = .0004) and stage II (P = .0065) Merkel cell carcinoma among skin cancers was complemented by an increasing proportion of stage III disease (P < .0001). A predominance of non-Hispanic White (96.4%), male (62.6%) patients with a mean age of 74.5 ± 10.8 years and Medicare coverage (73.5%) was observed. Stage I was the most common presenting stage at diagnosis (29.2%), followed by stages II (12.7%), III (11.0%), and IV (3.8%). Most Merkel cell carcinoma tumors grew outside the head and neck (53.4%) and showed a nodular growth pattern (66.0%) but no extracapsular lymph node (90.5%) or lymphovascular involvement (63.8%). Narrow-margin excision and radiation therapy (RT) were used in 75.2% and 56.3% of tumors, respectively. Wide-margin excision lead to improved overall survival (P < .001) versus narrow-margin excision, particularly in stage III (difference in the median overall survival rate [ΔmOS], 23.7 months; P < .001). RT showed a significant OS benefit (P =.006), most pronounced in stage II (ΔmOS, 37.8 months) followed by stage I (ΔmOS, 16.1 months; P < .001). The survival benefit with primary-site RT (ΔmOS, 24.0 months) was higher than that with primary-site/lymph node RT (ΔmOS, 5.2 months; P < .001). Wide-margin excision independently predicted improved OS (hazard ratio, 0.577; 95% CI, 0.403-0.826; P = .003) versus narrow-margin excision and RT predicted better OS (hazard ratio, 0.608; 95% CI, 0.424-0.873; P = .007) versus no RT on multivariable analysis.
