RESUMO
BACKGROUND: Striae are fine lines on the body that occur following rapid skin stretching (i.e., following pregnancy, puberty, weight change). The aim of this systematic review was to assess the current literature on treatment outcomes associated with striae. OBJECTIVE: (1) To assess the efficacy and safety of different treatment options reported for striae and (2) to determine the most efficient treatment options for each subtype of striae. METHODS: A systematic search was performed on MEDLINE, Embase, and PubMed with no publication date or language restrictions. All articles with original data and treatment outcomes were included. RESULTS: One hundred fifty-one studies on the treatment of striae met inclusion criteria (83% female, mean age at diagnosis = 30.2), and 4,806 treatment outcomes of striae were described. Energy-based devices were the most reported modality (56%; n = 2,699/4,806), followed by topicals (19%; n = 919/4,806) and combinations (12%; n = 567/4,806). The highest rates of complete response were injection-based devices for striae distensae (7%; n = 12/172), CO 2 lasers for striae alba (4%; n = 12/341), and platelet-rich plasma injections for striae rubra (31%; n = 4/13). CONCLUSION: Treatment options for striae are varied, likely indicating a lack of effective treatments due to the diversity in striae subtypes. Improved outcomes in striae management may be achieved with additional research on factors that predict treatment response.

Hypertrophic scars (HTS) are elevated scars which occur due to abnormalities in wound healing after injury and may be associated with pain, pruritus and functional impairment. Despite multiple available treatment options, there is no universal approach to treating HTS. We searched the Web of Science (Core Collection), MEDLINE and EMBASE databases. Title, abstract and full-text screening, along with data extraction, were performed in duplicate. Risk of bias was assessed using the Cochrane risk-of-bias tool. The Vancouver Scar Scale (VSS) scores and mean differences were used for meta-analysis. We screened 3800 abstracts and included 34 randomised controlled trials evaluating treatments for HTS in adults. Silicone and laser modalities improved VSS scores by 5.06 (95% CI: 6.78, 3.34) and 3.56 (95% CI: 5.58, 1.54), respectively. Intralesional triamcinolone combined with silicone or 5-fluorouracil was superior to intralesional triamcinolone monotherapy. Limitations of this study include exclusion of studies which did not utilise VSS, and pooling of studies based on common modalities. Further studies are needed to examine the efficacy of existing and emerging treatment modalities for HTS. Our study supports the treatment of HTS in adults with silicone gel or sheets, injected triamcinolone (preferably combined with 5-fluorouracil or silicone products), pulsed dye laser and fractionated CO2 laser.

Introduction: The skin of subjects with dry, flaking, and/or scaling conditions is characterized by decreased water and skin lipids content among other findings. It is well understood that daily use of gentle cleansers and moisturizers may help to restore and maintain an optimal skin barrier function. A cohort study of patients with dry skin was developed to evaluate efficacy of daily use of a ceramide containing cleanser and cream that also has salicylic acid. Methods: Thirty-five adults with mild-to-moderate dry skin conditions were recruited from four dermatology centers in Canada. With consent, the subjects received twice daily treatment with the ceramides containing cleanser and cream that also has salicylic acid. Physician and subject assessed skin condition comparing baseline versus (day 0) versus day 28 (end) was scored using the Dry skin classification scale and the Global Aesthetic Improvement Scale (GAIS). Subjects also rated satisfaction, product features, quality of life aspects, safety, and tolerability. Results: Thirty-four subjects completed the treatment and study period; one was lost to follow up. Daily use of the evaluated cleanser and moisturizer significantly improved skin condition when comparing day 0 versus day 28 (+/- 5 days (end)) results. Both the physicians and subjects using the dry skin classification scale and GAIS scored a significant improvement of the dry skin condition. After treatment subjects reported a significant improvement in the quality of their professional life, self-image, and social life. The products were shown to be safe, comfortable, and well tolerated. Conclusion: The results indicated the cleanser and moisturizer to offer an effective, easy and comfortable option for dry skin conditions. J Drugs Dermatol. 2019;18(1):80-85.

BACKGROUND:: There is ongoing development of new therapies for psoriasis, including biologic and systemic agents such as interleukin-17, interleukin-23, and phosphodiesterase-4 inhibitors. The development of these agents has changed the landscape of psoriasis treatment options. OBJECTIVE:: The objective of this study was to characterize the impact of newer biologic and systemic agents approved by June 2016 on patient outcomes. We sought to evaluate and compare biologic users and nonbiologic systemic users with respect to their treatment awareness and satisfaction. METHODS:: We conducted a national Canadian survey from July to September 2016 on adult patients with moderate-to-severe psoriasis using biologic agents or nonbiologic systemic agents as their current primary treatment modality. Patients were asked to evaluate their overall satisfaction with their treatment agent and their awareness of other treatment options. Responses from biologic and nonbiologic systemic users were compared. RESULTS:: Overall, 343 participants were included (biologic users: n = 218; nonbiologic users: n = 125). Treatment satisfaction: Biologic users had a higher overall satisfaction score than nonbiologic users ( P < .001). Among nonbiologic agents, apremilast (62%) was associated with the highest satisfaction proportion. Among biologic agents, ustekinumab (77%) and adalimumab (72%) were associated with the highest proportions of satisfaction. With respect to treatment awareness, 30% of nonbiologic patients did not have enough information to form an opinion about biologics. CONCLUSIONS:: This study demonstrates the greater treatment satisfaction of biologic users compared with nonbiologic users for moderate-to-severe psoriasis. Given that nearly one-third of nonbiologic users did not have enough information to form an opinion about biologic agents, physicians may consider counselling these patients on the use of biologic agents for psoriasis management.

Rosacea is a chronic facial inflammatory dermatosis characterized by background facial erythema and flushing and may be accompanied by inflammatory papules and pustules, cutaneous fibrosis and hyperplasia known as phyma, and ocular involvement. These features can have adverse impact on quality of life, and ocular involvement can lead to visual dysfunction. The past decade has witnessed increased research into pathogenic pathways involved in rosacea and the introduction of novel treatment innovations. The objective of these guidelines is to offer evidence-based recommendations to assist Canadian health care providers in the diagnosis and management of rosacea. These guidelines were developed by an expert panel of Canadian dermatologists taking into consideration the balance of desirable and undesirable outcomes, the quality of supporting evidence, the values and preferences of patients, and the costs of treatment. The 2015 Cochrane review "Interventions in Rosacea" was used as a source of clinical trial evidence on which to base the recommendations.

BACKGROUND: Infectious mononucleosis is common among adolescents and young adults. Although the majority of cases resolve spontaneously, life-threatening manifestations, and complications have been recognised. OBJECTIVE: The purpose of this article is to familiarize clinicians with the clinical manifestations, evaluation, diagnosis, and management of infectious mononucleosis. METHODS: A search was conducted in October 2022 in PubMed Clinical Queries using the key terms "infectious mononucleosis" OR "Epstein-Barr virus" OR "EBV". The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the aforementioned search was used in the compilation of the present article. RESULTS: Infectious mononucleosis, caused by Epstein-Barr virus, most commonly affects adolescents and adults aged 15 to 24 years. Epstein-Barr virus is transmitted primarily in saliva. Infectious mononucleosis is characterized by a triad of fever, tonsillar pharyngitis, and lymphadenopathy. Fatigue may be profound but tends to resolve within three months. Periorbital and/or palpebral edema, typically bilateral, occurs in one-third of patients. Splenomegaly and hepatomegaly occur in approximately 50% and 10% of cases, respectively. A skin rash, which is usually widely scattered, erythematous, and maculopapular, occurs in approximately 10 to 45% of cases. Peripheral blood leukocytosis is observed in most patients; lymphocytes make up at least 50% of the white blood cell differential count. Atypical lymphocytes constitute more than 10% of the total lymphocyte count. The classic test for infectious mononucleosis is the demonstration of heterophile antibodies. The monospot test is the most widely used method to detect the serum heterophile antibodies of infectious mononucleosis. When confirmation of the diagnosis of infectious mononucleosis is required in patients with mononucleosis-like illness and a negative mono-spot test, serologic testing for antibodies to viral capsid antigens is recommended. Infectious mononucleosis is a risk factor for chronic fatigue syndrome. Spontaneous splenic rupture occurs in 0.1 to 0.5% of patients with infectious mononucleosis and is potentially life-threatening. Treatment is mainly supportive. Reduction of activity and bed rest as tolerated are recommended. Patients should be advised to avoid contact sports or strenuous exercise for 8 weeks or while splenomegaly is still present. Most patients have an uneventful recovery. CONCLUSION: Infectious mononucleosis is generally a benign and self-limited disease. Prompt diagnosis is essential to avoid unnecessary investigations and treatments and to minimize complications. Splenic rupture is the most feared complication. As avoiding exposure to EBV is almost impossible, the most effective way to prevent EBV infection and infectious mononucleosis is the development of an effective, safe, and affordable EBV vaccine that can confer life-long immunity.

BACKGROUND: Lichen striatus is a benign dermatosis that affects mainly children. This condition mimics many other dermatoses. OBJECTIVE: The purpose of this article is to familiarize pediatricians with the clinical manifestations of lichen striatus to avoid misdiagnosis, unnecessary investigations, unnecessary referrals, and mismanagement of lichen striatus. METHODS: A search was conducted in June 2023 in PubMed Clinical Queries using the key term "Lichen striatus". The search strategy included all observational studies, clinical trials, and reviews published within the past ten years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of this article. RESULTS: Lichen striatus is a benign self-limited T-cell mediated dermatosis characterized by a linear inflammatory papular eruption seen primarily in children. The onset is usually sudden with minimal or absent symptomatology. The eruption in typical lichen striatus consists of discrete, skin- colored, pink, erythematous, or violaceous, flat-topped, slightly elevated, smooth or scaly papules that coalesce to form a dull red, potentially scaly, interrupted or continuous band over days to weeks. Although any part of the body may be involved, the extremities are the sites of predilection. Typically, the rash is solitary, unilateral, and follows Blaschko lines. In dark-skinned individuals, the skin lesions may be hypopigmented at onset. Nails may be affected alone or, more commonly, along with the skin lesions of lichen striatus. The differential diagnoses of lichen striatus are many and the salient features of other conditions are highlighted in the text. CONCLUSION: Lichen striatus is a self-limited condition that often resolves within one year without residual scarring but may have transient post-inflammatory hypopigmentation or hyperpigmentation. As such, treatment may not be necessary. For patients who desire treatment for cosmesis or for the symptomatic treatment of pruritus, a low- to mid-potency topical corticosteroid or a topical immunomodulator can be used. A fading cream can be used for post-inflammatory hyperpigmentation.
RESUMO
BACKGROUND: Pinworm infestation is an important public health problem worldwide, especially among children 5 to 10 years of age in developing countries with temperate climates. The problem is often overlooked because of its mild or asymptomatic clinical manifestations. OBJECTIVE: The purpose of this article was to familiarize pediatricians with the diagnosis and management of pinworm infestation. METHODS: A search was conducted in August 2023 in PubMed Clinical Queries using the key terms "Enterobius vermicularis," OR "enterobiasis," OR "pinworm." The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS: Enterobiasis is a cosmopolitan parasitosis caused by Enterobius vermicularis. It affects approximately 30% of children worldwide and up to 60% of children in some developing countries. Predisposing factors include poor socioeconomic conditions, inadequate sanitation, poor personal hygiene, and overcrowding. Children aged 5 to 14 years have shown the highest prevalence of enterobiasis.. Egg transmission is mainly by the fecal-oral route. Approximately 30 to 40% of infested patients do not show any clinical symptoms of the disease. For symptomatic patients, the most common presenting symptom is nocturnal pruritus ani. The diagnosis of E. vermicularis infection is best established by the cellophane tape test. The sensitivity of one single test is around 50%; however, the sensitivity increases to approximately 90% with tests performed on three different mornings. If a worm is visualized in the perianal area or the stool, a pathological examination of the worm will yield a definitive diagnosis. As pinworms and eggs are not usually passed in the stool, examination of the stool is not recommended. The drugs of choice for the treatment of pinworm infestation are mebendazole (100 mg), pyrantel pamoate (11 mg/kg, maximum 1 g), and albendazole (400 mg), all of the above-mentioned drugs are given in a single dose and repeated in two weeks. Mebendazole and albendazole are both adulticidal and ovicidal, whereas pyrantel pamoate is only adulticidal. Given their safety and effectiveness, mebendazole and albendazole are currently the best available drugs for the treatment of pinworm infestation. For pregnant women, pyrantel is preferred to mebendazole and albendazole. Treatment of all household members should be considered, especially if there are multiple or repeated symptomatic infections because reinfection is common even when effective medication is given. CONCLUSION: In spite of effective treatment of pinworm infestation, recurrences are common. Recurrences are likely due to repeated cycles of reinfection (particularly, autoinfection) because of the short life span of adult pinworms. Good personal hygiene, such as frequent handwashing, especially after bowel movements and before meals, clipping of fingernails, avoidance of finger-sucking, nail-biting, and scratching in the anogenital area, are important preventive measures. Treatment of all household members should be considered, especially if there are multiple or repeated symptomatic infections.

Background: Guttate psoriasis is common and affects 0.5-2% of individuals in the paediatric age group. This review aims to familiarize physicians with the clinical manifestations, evaluation, diagnosis and proper management of guttate psoriasis. Methods: A search was conducted in July 2023 in PubMed Clinical Queries using the key term "guttate psoriasis". The search strategy included all observational studies, clinical trials and reviews published within the past 10 years. The information retrieved from the search was used in the compilation of the present article. Results: Guttate psoriasis typically presents with an abrupt onset of numerous, small, scattered, tear-drop-shaped, scaly, erythematous, pruritic papules and plaques. Sites of predilection include the trunk and proximal extremities. There may be a history of preceding streptococcal infection. Koebner phenomenon is characteristic. Guttate psoriasis may spontaneously remit within 3-4 months with no residual scarring, may intermittently recur and, in 40-50% of cases, may persist and progress to chronic plaque psoriasis. Given the possibility for spontaneous remission within several months, active treatment may not be necessary except for cosmetic purposes or because of pruritus. On the other hand, given the high rates of persistence of guttate psoriasis and progression to chronic plaque psoriasis, some authors suggest active treatment of this condition. Conclusion: Various treatment options are available for guttate psoriasis. Triggering and exacerbating factors should be avoided if possible. Topical corticosteroids alone or in combination with other topical agents (e.g. tazarotene and vitamin D analogues) are the most rapid and efficient treatment for guttate psoriasis and are therefore the first-line treatment for mild cases. Other topical therapies include vitamin D analogues, calcineurin inhibitors, anthralin, coal tar and tazarotene. Ultraviolet phototherapy is the first-line therapy for moderate-to-severe guttate psoriasis, as it is more practical than topical therapy when treating widespread or numerous small lesions. Systemic immunosuppressive and immunomodulatory therapies (e.g. methotrexate, cyclosporine, retinoids, fumaric acid esters and biologics) may be considered for patients with moderate-to-severe guttate psoriasis who fail to respond to phototherapy and topical therapies.
RESUMO
BACKGROUND: Group A ß-hemolytic streptococcus (GABHS) is the leading bacterial cause of acute pharyngitis in children and adolescents worldwide. OBJECTIVE: This article aims to familiarize clinicians with the clinical manifestations, evaluation, diagnosis, and management of GABHS pharyngitis. METHODS: A search was conducted in December 2022 in PubMed Clinical Queries using the key term "group A ß-hemolytic streptococcal pharyngitis". This review covers mainly literature published in the previous ten years. RESULTS: Children with GABHS pharyngitis typically present with an abrupt onset of fever, intense pain in the throat, pain on swallowing, an inflamed pharynx, enlarged and erythematous tonsils, a red and swollen uvula, enlarged tender anterior cervical lymph nodes. As clinical manifestations may not be specific, even experienced clinicians may have difficulties diagnosing GABHS pharyngitis solely based on epidemiologic or clinical grounds alone. Patients suspected of having GABHS pharyngitis should be confirmed by microbiologic testing (e.g., culture, rapid antigen detection test, molecular point-of-care test) of a throat swab specimen prior to the initiation of antimicrobial therapy. Microbiologic testing is generally unnecessary in patients with pharyngitis whose clinical and epidemiologic findings do not suggest GABHS. Clinical score systems such as the Centor score and McIssac score have been developed to help clinicians decide which patients should undergo diagnostic testing and reduce the unnecessary use of antimicrobials. Antimicrobial therapy should be initiated without delay once the diagnosis is confirmed. Oral penicillin V and amoxicillin remain the drugs of choice. For patients who have a non-anaphylactic allergy to penicillin, oral cephalosporin is an acceptable alternative. For patients with a history of immediate, anaphylactic-type hypersensitivity to penicillin, oral clindamycin, clarithromycin, and azithromycin are acceptable alternatives. CONCLUSION: Early diagnosis and antimicrobial treatment are recommended to prevent suppurative complications (e.g., cervical lymphadenitis, peritonsillar abscess) and non-suppurative complications (particularly rheumatic fever) as well as to reduce the severity of symptoms, to shorten the duration of the illness and to reduce disease transmission.
