Xerosis, pruritus, and rash make the clinical diagnosis. Adequate skin care and regular emollient use are key in management. Topical corticosteroids are the first-line treatment for AD flare-ups. Wet wrap therapy can improve AD severity and extent. Topical calcineurin inhibitors are second-line treatments. Emollient use, topical corticosteroids and calcineurin inhibitors, and bleach baths can help prevent flare-ups. Patients with refractory AD that might require immunomodulatory treatments, such as dupilumab (Dupixent), Janus kinase inhibitors, or phototherapy, should be referred to a dermatologist. Seborrheic dermatitis (SD) is a common, chronic, relapsing, inflammatory condition that involves sebaceous skin areas. Infection with Malassezia species and the inflammatory response to it are the probable etiologies. The clinical diagnosis is made by the presence of hallmark greasy, yellow scales on the scalp or face. Infantile SD most commonly involves the scalp and forehead and typically is self-limited. In infants, application of emollients followed by hair brushing and shampooing may be effective. In infants and children, if the condition does not improve with this treatment, topical ketoconazole shampoo, gel, or lotion is safe and effective. Refractory cases of SD can be managed with topical corticosteroids and calcineurin inhibitors.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"541 ","pages":"27-38"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141427826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If available, potassium hydroxide preparation should be performed to confirm diagnosis of tinea capitis or onychomycosis. In some cases, fungal culture, UV light examination, or periodic acid-Schiff stain can be helpful. Topical drugs are effective for tinea corporis, tinea cruris, and tinea pedis. Tinea incognito is an atypical presentation that usually requires systemic treatment. Management of tinea capitis always requires oral drugs. Oral drugs are preferred for onychomycosis treatment but should not be prescribed without confirmation of fungal infection. Localized cases of tinea versicolor can be managed with topical drugs, but oral drugs might be needed for severe, widespread, or recurrent cases. Warts are superficial human papillomavirus infections. Common treatments include irritant, destructive (eg, cryotherapy), immune stimulant (eg, intralesional Candida antigen), and debridement and excision methods. Scabies infestation results in intensely itchy papules, nodules, or vesicles. Mites and burrows on the skin are pathognomonic but difficult to identify. Dermoscopy, particularly with UV light, can make identification easier. Topical permethrin and oral ivermectin are two of the most commonly used treatments. All household and close contacts should be treated regardless of the presence or absence of symptoms.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"541 ","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141427829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Common Skin Conditions in Children and Adolescents: Acne.","authors":"Mengyi Zha, Richard Usatine","doi":"","DOIUrl":"","url":null,"abstract":"Acne is a chronic, recurrent inflammatory condition of the pilosebaceous unit. It affects approximately 85% of adolescents and creates significant psychosocial and financial burdens. The pathogenesis involves altered follicular growth and differentiation, microbial colonization with Cutibacterium acnes, increased sebum production influenced by androgen levels, and inflammation. Evidence-based risk factors include family history and body mass index. Diagnosis of acne is clinical, according to patient age and acne morphology and severity. Setting treatment expectations is an important aspect of management. For mild acne, benzoyl peroxide is an effective first-line drug as monotherapy or in combination with a topical retinoid and/or topical antibiotic. Oral tetracyclines are first-line drugs as part of a multipart treatment regimen for moderate to severe acne for patients older than 8 years. Oral isotretinoin is the first-line drug for moderate to severe inflammatory acne. Because of its teratogenic effects, its prescribing is monitored through the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) program. Prescribing oral or topical antibiotics as monotherapy for acne is not recommended, as this may increase microbial resistance. Combined oral contraceptives and spironolactone are used as adjunctive therapies in female adolescents. Patients with skin of color, pregnant patients, and transgender or gender diverse patients warrant special considerations in acne management.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"541 ","pages":"7-13"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141427825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Common Skin Conditions in Children and Adolescents: Bacterial Infections.","authors":"Mengyi Zha, Richard Usatine","doi":"","DOIUrl":"","url":null,"abstract":"Bacterial skin infections represent a significant health care burden. Cellulitis and erysipelas are rapidly spreading, painful, superficial skin infections, usually caused by streptococci or Staphylococcus aureus. Folliculitis is an infection of hair follicles mostly caused by S aureus. Simple folliculitis typically is self-limited. Topical benzoyl peroxide is a first-line nonantibiotic treatment. Mupirocin and clindamycin are topical antibiotic options. For treatment-resistant cases, oral cephalexin or dicloxacillin is an appropriate option. Impetigo is a common, self-limited infection in children. Bullous impetigo is caused by S aureus, and nonbullous impetigo is caused by beta-hemolytic streptococci, S aureus, or both. In most cases, topical mupirocin or retapamulin (Altabax) is effective. Oral antibiotics should be considered for household outbreaks or patients with multiple lesions. Abscesses are red, painful collections of purulence in the dermis and deeper tissues caused by S aureus or polymicrobial infections. Furuncles are abscesses of a hair follicle, whereas carbuncles involve several hair follicles. In recurrent cases of these lesions, culture of the exudate is recommended. Abscess, furuncle, and carbuncle management consists of incision and drainage. Oral antibiotics are not necessary in most cases but should be prescribed for patients with severe immunocompromise or systemic signs of infection. In bacterial skin infections, methicillin-resistant S aureus coverage should be considered for patients with infections that have not improved with treatment.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"541 ","pages":"14-19"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141427827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gastrointestinal Conditions: Peptic Ulcer Disease.","authors":"Justin M Bailey","doi":"","DOIUrl":"","url":null,"abstract":"Peptic ulcer disease (PUD) involves ulceration of the mucosa in the stomach and/or proximal duodenum. The main causes are Helicobacter pylori infection and nonsteroidal anti-inflammatory drug (NSAID) use. PUD occurs in 5% to 10% of people worldwide, but rates have decreased by more than half during the past 20 years. This reduction is thought to be because of H pylori management, more conservative use of NSAIDs, and/or widespread use of proton pump inhibitors (PPIs). Common symptoms include postprandial abdominal pain, nausea, vomiting, and weight loss. These symptoms have broad overlap with those of other conditions, making clinical diagnosis difficult. Endoscopy is the gold standard for diagnosis, especially in older patients and those with alarm symptoms, but a test-and-treat strategy (noninvasive test for H pylori and treat if positive) can be used for younger patients with no alarm symptoms. Numerous treatment regimens are available, all of which include PPIs plus antibiotics. As an alternative to PPIs, a new triple therapy with vonoprazan (which blocks acid production) plus antibiotics has been approved and appears to be superior to conventional therapy with PPIs plus antibiotics. At least 4 weeks after treatment, repeat testing for H pylori should be obtained to confirm cure. When possible, NSAIDs should be discontinued; when not possible, antisecretory cotherapy should be considered.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"540 ","pages":"16-23"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141066695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gastrointestinal Conditions: Pancreatitis.","authors":"Justin M Bailey","doi":"","DOIUrl":"","url":null,"abstract":"Acute pancreatitis is among the most common gastrointestinal disorders requiring hospitalization. The main causes are gallstones and alcohol use. Patients typically present with upper abdominal pain radiating to the back, worse with eating, plus nausea and vomiting. Diagnosis requires meeting two of three criteria: upper abdominal pain, an elevated serum lipase or amylase level greater than 3 times the normal limit, and imaging findings consistent with pancreatitis. After pancreatitis is diagnosed, the Atlanta classification and identification of the systemic inflammatory response syndrome can identify patients at high risk of complications. Management includes fluid resuscitation and hydration maintenance, pain control that may require opioids, and early feeding. Feeding recommendations have changed and \"nothing by mouth\" is no longer recommended. Rather, oral feeding should be initiated, as tolerated, within the first 24 hours. If it is not tolerated, enteral feeding via nasogastric or nasojejunal tubes should be initiated. Antibiotics are indicated only with radiologically confirmed infection or systemic infection symptoms. Surgical or endoscopic interventions are needed for biliary pancreatitis or obstructive pancreatitis with cholangitis. One in five patients will have recurrent episodes of pancreatitis; alcohol and smoking are major risk factors. Some develop chronic pancreatitis, associated with chronic pain plus pancreatic dysfunction, including endocrine failure (insulin insufficiency) and/or exocrine failure that requires long-term vitamin supplementation.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"540 ","pages":"30-41"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141066186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gastrointestinal Conditions: Acute Infectious Gastroenteritis and Colitis.","authors":"Justin M Bailey","doi":"","DOIUrl":"","url":null,"abstract":"Gastroenteritis is inflammation of the stomach and intestines; colitis is inflammation of the colon. Viruses are the most common cause, followed by bacteria and parasites. Incidence of the various infections varies by age, sex, location, and vaccine availability; vaccination has reduced rotavirus infections by as much as 90% in children. Postinfectious complications include irritable bowel syndrome (IBS) and lactose intolerance. Approximately 9% of patients with acute gastroenteritis or colitis develop postinfectious IBS, which accounts for more than 50% of all IBS cases. The diagnostic approach to gastroenteritis and colitis varies with symptom severity. Microbial studies are not needed with mild symptoms that resolve within a week, but longer-lasting or more severe symptoms (including bloody stool) warrant microbial studies. In addition, recent antibiotic exposure should prompt testing for Clostridioides difficile. Multiplex antimicrobial testing is preferred; stool cultures and microscopic stool examinations are no longer first-line tests. Management depends on severity. Patients with mild or moderate symptoms are treated with oral hydration if tolerated; nasogastric or intravenous hydration are used for those with more severe illness. In addition, antiemetic, antimotility, and/or antisecretory drugs can be used for symptom control. Antimicrobial therapy is indicated for C difficile infections, travel-related diarrhea, other bacterial infections with severe symptoms, and parasitic infections.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"540 ","pages":"24-29"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141066178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gastrointestinal Conditions: Gastroesophageal Reflux Disease.","authors":"Justin M Bailey","doi":"","DOIUrl":"","url":null,"abstract":"Gastroesophageal reflux disease (GERD) affects more than 20% of adults. Risk factors include older age, obesity, smoking, and sedentary lifestyle. Lower esophageal sphincter (LES) dysfunction is a primary cause. Classic symptoms include heartburn and regurgitation. With classic symptoms, proton pump inhibitors (PPIs) can be prescribed without further testing; PPIs should be taken on an empty stomach. Patients with atypical symptoms and those not benefiting from management should undergo esophagogastroduodenoscopy (EGD), and potentially pH and impedance testing to confirm GERD or identify other conditions. This is important because GERD increases risk of esophageal erosions/stricture, Barrett esophagus, and esophageal adenocarcinoma. However, a large percentage of adults taking PPIs have no clear indication for treatment, and PPIs and other antisecretory therapy should be tapered off if possible. Of note, vonoprazan, a new drug approved by the Food and Drug Administration (FDA), has shown superiority to PPIs. In addition to pharmacotherapy, lifestyle changes are indicated, including losing weight if overweight, not lying down after meals, and ceasing tobacco use. Procedural interventions, including fundoplication and magnetic sphincter augmentation, can be considered for patients wishing to discontinue drugs or with symptoms unresponsive to PPIs. Procedural interventions are effective for the first 1 to 3 years, but effectiveness decreases over time.","PeriodicalId":38325,"journal":{"name":"FP essentials","volume":"540 ","pages":"7-15"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141066184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
