RESUMO
Scabies is a human ectoparasitosis caused by Sarcoptes scabei var. hominis. World-wide around 300 million patients are affected. Infants and children have the highest incidence rates. Poverty and overcrowding are social factors contributing to a higher risk of transmission and treatment failure. The leading symptom of the infestation is itch. Complications are bacterial infections that are responsible for mortality. Diagnosis is clinical. Non-invasive imaging technologies like dermoscopy can be used. Polymerase chain reaction (PCR) is less sensitive and specific than microscopy of skin scrapings. Treatment of choice is topical permethrin 5%. Ivermectin is the only oral drug FDA-approved for scabies. It should be used in cases non-responsive to topical therapy and in case of high number of infested patients in addition to topical therapy. Pseudo-resistance to treatment is not uncommon. New drugs are on the horizon. What is Known: ⢠Pruritus is the leading symptom causing sleep disturbances and scratching with the risk of secondary bacterial infections. ⢠Treatment failure is related to inappropriate application of topical drugs and asymptomatic family members. What is New: ⢠COVID-19 pandemic and migration are contributing to an increased incidence of scabies. ⢠New compounds to treat scabies are on the horizon.

Kerion Celsi is an inflammatory, deep fungal infection of the scalp. It is rare in neonates but gets more common in children about 3 years and older. It represents with swelling, boggy lesions, pain, alopecia and purulent secretions. Secondary bacterial infection is not unusual after maceration. Extracutaneous manifestations include regional lymphadenopathy, fever and very rare fungemia. Id-reactions can occur. Diagnosis is based on clinical suspicion, clinical examination and medical history. Diagnosis should be confirmed by microscopy, fungal culture and molecular procedures. The most common isolated fungal species are anthropophilic Trichophyton (T.) tonsurans and zoophilic Microsporum (M.) canis, while geophilic species and moulds rarely cause Kerion Celsi. Treatment is medical with systemic and topical antifungals supplemented by systemic antibiotics when necessary, while surgery needs to be avoided. Early and sufficient treatment prevents scarring alopecia. The most important differential diagnosis is bacterial skin and soft tissue infections.

Cheilitis is a common inflammatory disorder of the vermillion and adjacent skin of the lips. A special type is angular cheilitis. The disease has a mixed etiology, mostly with bacterial and fungal components. Angular cheilitis may be a clinical sign of an underlying disease. It has two age peaks: one during childhood and another in adults. It becomes more frequent with aging. Clinical presentation, differential diagnoses, and treatment are discussed. Angular cheilitis is of importance in primary care of patients, in geriatrics, dentistry, pediatrics, internal medicine, and in dermatology.
RESUMO
Rosacea is a facial inflammatory disorder that shows an increasing incidence with age. While rosacea is common > 60 years of age, pediatric rosacea is uncommon. Diagnostic criteria are based on clinical symptoms. Laboratory investigations and histopathology are only needed to exclude other differential diagnoses. There are several subtypes such as erythemato-telangiectatic, papulo-pustular, periorificial, and granulomatous variants. In contrast to adult rosacea, phymatous subtypes do not belong to pediatric rosacea. A special subtype seen in infants and children is an idiopathic facial aseptic granuloma. Genetic and environmental factors contribute to its pathogenesis. Treatment options are in analogy to adult rosacea classified into topical and systemic drugs. In the case of oral tetracyclines, discoloration of teeth and impairment of enamel are possible adverse events. CONCLUSION: Pediatric rosacea belongs to the rosacea spectrum but has peculiarities compared to the adult subtype. WHAT IS KNOWN: ⢠Rosacea is a chronic inflammatory disorder different from acne. ⢠Rosacea gets more common with advanced age. WHAT IS NEW: ⢠Pediatric rosacea is an uncommon subtype with peculiar clinical presentation. ⢠Demodicosis is very rare in immunocompetent children.

This is a retrospective analysis of all lipedema patients treated by tumescent liposuction at our department in the years 2007-2021: We performed 519 liposuctions in 178 patients with a mean age of 45⯱ 15.5 years. By the stage of lipedema the mean age increased significantly, what underlines the concept of lipedema as a chronic progressive disorder. Three-thirds of patients reported at least one comorbidity. The most common were arterial hypertension (32.58%), obesity (24.16%), and hypothyroidism (20.79%). We removed a mean lipoaspirate volume of 4905⯱ 2800â¯mL. A major target for treatment is pain reduction. All patients reported at least a 50% pain reduction after liposuction, while 96 achieved a pain reduction ≥â¯90%. The pre-operative pain intensity (pâ¯= 0.000) and the lipedema stage (pâ¯= 0.032) exerted a significant impact on absolute pain reduction. There was no association of pain reduction to volume loss. The post-operative rate of adverse events was 2.89%. Liposuction in tumescent anesthesia is an effective and safe method to reduce both pain and volume in patients with lipedema.

Diaper dermatitis (DD) is an umbrella term with different clinical presentations, pathophysiology, treatments, and outcomes. The major subtypes include irritant contact dermatitis and candida-associated DD. In case of atypical presentation or unresponsiveness to treatment, other differential diagnoses should be considered. Although DD can occur at any age, it peaks in newborns and infants <â¯2 years of age. We will focus on this age group in our narrative review.
RESUMO
Infantile cavernous hemangioma is a benign vascular tumor in childhood. Cavernous hemangiomas have a tendency of slow enlargement with subsequent complications such as ulceration and bleeding. We report a case of a large cavernous hemangioma affecting the median upper lip in an 11-year-old girl. The lesion was growing and painful on pressure. The patient felt stigmatized. Treatment was wished for by patient and parents. After careful examination including Doppler ultrasound, we suggested a combined approach. In the first step the lesion was coagulated with an intralesional neodymium-YAG laser using a blunt tip. In the second step, immediately after the action of the laser, the lesion was removed completely by surgery. Defect closure was realized with bilateral tissue-expanding vermillion myocutaneous flaps. The patient was followed-up to 5 months. Disfigurement and functional impairment were eliminated. The result was satisfying for both patient and parents. Vascular lesions of the upper lip-particularly when close to Cupid's bow-can become disfiguring and cause functional impairment. We propose a combined approach with intralesional neodymium-YAG laser photocoagulation to avoid bleeding and to shrink the lesion before complete surgical removal. For defect closure, bilateral tissue-expanding vermillion myocutaneous flaps (Goldstein technique modified by Sawada) were used.
RESUMO
Cutaneous melanoma is the major cause of mortality from all skin cancers. The treatment has been revolutionized in recent years by introduction of immunotherapy and targeted therapy for melanoma patients Stages III and IV. Therefore, the role of surgery in melanoma treatment needs to be redefined. In this narrative review, we will focus on surgery for diagnosis, treatment of primary tumor, and metastases in the era of new and effective medical treatment options. Neoadjuvant therapy is currently investigated in several trials. Surgery for treatment-resistant metastases is another field of interest. In conclusion, surgery remains a cornerstone for diagnosis and treatment of primary melanoma. Therapeutic lymphadenectomy has lost importance while surgery in sentinel lymph node diagnostics and metastasectomy are useful in a tailored individual approach of combined treatments. There is a trend to less invasive surgical procedures.

Currently the most powerful tool in combating the COVID-19 pandemic is vaccination against SARS-CoV-2. A growing percentage of the world's population is being vaccinated. Various vaccines are worldwide on the market. Several adverse reactions have been reported as a part of post-marketing surveillance of COVID-19 vaccines. Among the possible adverse events, cutaneous vasculitis has occasionally been reported. We present a narrative review on cutaneous vasculitis related to COVID-19-vaccination to summarize clinical findings, histopathology, treatment and outcome. We searched for "COVID vaccine", "COVID vaccination" AND "cutaneous vasculitis" in PUBMED. Articles in English have been selected, from inception to December 2021, and analyzed for patient's characteristics, type of vaccine, time of appearance of cutaneous vasculitis and clinico-histopathologic type. Treatment and outcome have also been considered in this narrative review. Two new unpublished cases of ours were added. Cutaneous vasculitis is a rare adverse event to COVID-19 vaccination. It has been observed with mRNA and adenovirus-vector vaccines. IgA vasculitis, lymphocytic and ANCA-associated vasculitis, leukocytoclastic and urticarial vasculitis have been reported. This adverse event can occur after first or second shot. Most cases run a mild to moderate course. Cornerstone of medical treatment are systemic corticosteroids. Complete remission could be achieved in most patients. Vasculitis may not be considered as a contraindication of vaccination, being uncommonly reported and shows a favorable prognosis. The benefit of the vaccination remains high especially for immunocompromised patients. COVID-vaccine induced vasculitis is important in the differential diagnosis of purpuric and vasculitis disorders.

Nail psoriasis has a considerable negative impact on the quality of life by limiting the patient’s household chores, professional activities and social interactions. Treatment for nail psoriasis is often overlooked with treatment for skin and joint involvement being more emphasized. It is also challenging since the clinical improvement takes a long time to be observed and is often met with poor compliance with treatment. This review focuses on the various treatment options for nail psoriasis after review of literature. The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. Only articles available in English were considered for this review.

Vaccination against severe acute respiratory syndrome coronavirus type 2 (SARS-CoV2) has become a major tool in the battle against the coronavirus disease 2019 (COVID-19) pandemic. Numerous products have been developed and more are to come. Vaccination success varies greatly between different countries. There are a number of different vaccine types, such as mRNA, DNA vaccines, adenovirus vector vaccines, and full-length spike protein nanoparticles with a special matrix. The different types may also cause a different spectrum of adverse events. With mass vaccination, post-marketing surveillance for product safety becomes increasingly important. In this review, we discuss possible hypersensitivity and cutaneous adverse events related to SARS-CoV2 vaccination-from local reactions like COVID arm to systemic and severe reactions like anaphylaxis. Vaccination may also induce or exacerbate preexisting disorders such as herpes zoster infection. This review should provide information to tailor, whenever possible, vaccination to patients' needs. It is a contribution to patient safety as well. There is general consensus that the benefits of SARS-CoV2 vaccination currently outweigh the risks of possible adverse events.

BACKGROUND: It is generally acknowledged that the first morphological change of hidradenitis suppurativa/acne inversa (HS/AI) consists of infundibular plugging of the folliculosebaceous apocrine apparatus, which is followed by acute and chronic inflammation, cysts with sinus formation, and fibrosis. Alternatively, it has been hypothesized that HS/AI is primarily a neutrophilic autoinflammatory disease and that the follicular plugging typical of this disease is secondary to inflammation. OBJECTIVE: To review the sequence of the changes that mark the disease development, we have performed a histopathologic study on the surgical material from a series of axillary and inguinal/perineal cases. METHODS: The histologic material from surgery on Hurley's second and third stage HS/AI was retrieved and collected with the patients' clinical images. The virtually uninvolved skin peripheral to the lesions was studied together with the main inflammatory foci on vertical sections stained with hematoxylin-eosin and immunohistochemistry for the follicle sheaths. RESULTS: The fully developed lesions showed acute and chronic, suppurative and granulomatous inflammation overlapping fibrosis, cysts, and sinuses. Instead, the skin adjacent to florid inflammation showed plugging and dysmorphic alterations of the hair follicles associated with immunopathological changes of the inner root sheath keratin expression. CONCLUSION: Our observations coincide with the classical pathological studies on the progressive changes of HS/AI; however, in our specimens, the virtually normal skin peripheral to the fully developed lesions show seemingly initial follicular changes that suggest development error. This finding would support the hypothesis of combined mutation-induced epithelial differentiative defects and immunological derangement in HS/AI pathogenesis.

Introduction: Acne vulgaris is a chronic inflammatory skin disease of the pilosebaceous follicles that affects patients of all ages. Aim: Use of isotretinoin in the early stages of the disease to prevent subsequent lesions of acne, including prolonged treatment and acne scars at a later age. Material and methods: A retrospective, comparative study was carried between January 2010 and November 2018. The study population consisted of 90 children aged 9-18 years with acne. During treatment by isotretinoin the clinical evaluation was done every month. Patients were divided into three groups according to age. One of the qualification criteria was follow-up visits. Results: A total of 90 children (67.8% females; mean age: 13.5 years) were enrolled. In group A (30 individuals - aged 9-11) and B (30 individuals - aged 12-13), treatment was terminated 2 months after clinical improvement (mean: 3 months). In control group C (30 individuals - aged 14-18), treatment was carried out using average cumulative dose 135 mg/kg bw/day. All groups showed up for follow-up. after 1 to 8 years. In groups A and B, 13 people underwent a second acne treatment; in 3.33% oral isotretinoin was used, in 18.33% topical treatment. In group C, 30 (100%) individuals underwent a second acne treatment; in 20% oral isotretinoin was used, and 80% required a topical treatment. Acne scars and post acne hyperpigmentation have been documented in 73.33% in group C. Conclusions: Early, reasonable and short-term use of isotretinoin can reduce the incidence of acne in the future and reduce the occurrence of secondary acne symptoms.
RESUMO
Cutaneous squamous cell carcinoma (SCC) is the second most common non-melanoma skin cancer among Caucasians. We analyzed our data on tumors been treated between 2006 and 2016 at the Skin Cancer Center of an academic teaching hospital. Thousand hundred and ninety-four patients with 1296 SCC have been identified including 804 males (67.3%) and 390 females (32.7%). The mean age among females was significantly higher with (83.9 ± 7.9) years compared with males ([79.3 ± 8.1] years; P < .001). The most common tumor localizations were outer ears (n = 227, 17.5%), scalp (216, 16.7%), and forehead (215, 16.6%). The majority of tumors was stage I. 31.9% of patients had previous SCC or Bowen's cancer, 29.1% had actinic keratoses. Major non-dermatological comorbidities were cardiovascular diseases and diabetes. SCC were treated by delayed Mohs surgery. First Mohs procedure resulted in R0 status in 83.9%. Most cases with R1 resection were located on nose and eyelids. For a subpopulation of patients (n = 105), a structured questionnaire study evaluated changes in sun protection behavior after skin cancer. After the confirmed diagnosis of a cutaneous SCC concerns about harm to the skin by intense sunlight was reported by 78.4% (76) of participants, with 92.0% among females versus 73.6% among males. Eighty percent of females and 76.8% of males wanted to care more about sun-protection in the future, spend less time 84.0% (females) and 72.5% (males) in the sun, and adapt their leisure activities for a better sun protection in 92.0% (females) and 81.9% (males). Secondary prevention in males needs improvement.

Tear trough deformities can be a sign of facial aging and exert a negative impact in facial attractiveness. Surgical techniques and adipose tissue transfer have been used to improve tear trough deformity. In recent years, minimal invasive procedures such as soft tissue filler injections became more popular. We report a retrospective evaluation of 45 Caucasian female patients ≥40 years (mean age of [58.8 ± 8.9] years). Severity of tear trough was classified according to Hirmand: 3 as grade I, 28 as grade II, and 14 grade III tear trough deformities. We used a monophasic hyaluronic acid, low G prime filler placed inferior to the lateral orbital thickening. On average, 0.4 ml of hyaluronic acid (HA) filler were injected per side. The improvement was I grade 29 patients and II grades in 16 patients. The improvement lasted (10.8 ± 2.3) months. No severe adverse events were noted. Vascular danger zones can be avoided.

Lipedema is a painful, underdiagnosed adipose tissue disorder, characterized by symmetrical swelling of the extremities due to subcutaneous fat deposition in the buttocks, thighs, legs, and arms, sparing the most distal part of the extremities. Although etiology and pathogenesis of lipedema is unclear, possible role of hormonal and genetic factors have been proposed previously. Patients with lipedema suffer from pain, easy bruising, tenderness, and disfigurement. Pain is the leading symptom in lipedema. Since the pain is associated with depression and impaired quality of life, reduction of pain is the major therapeutic approach. Pain in lipedema is attributed to allodynia, exaggerated sympathetic signaling, and estrogens. Although the mechanism of pain in lipedema is uncertain, effective treatment of lipedema should provide a satisfactory pain reduction. Efficacy of the conservative treatment is a matter of debate. Microcannular tumescent liposuction is the most effective therapeutic option for lipedema. There is a large body of evidence that this procedure significantly reduces pain in patients with lipedema.

BACKGROUND: The search for aesthetic non-surgical procedures is growing. The use of polymethylmethacrylate (PMMA) as a filling material in the nose represents one of the many options among these aesthetic procedures. Its use, however, can lead to complications. The treatment of these complications is often challenging. METHODS: We performed a retrospective clinical analysis of the medical records of patients undergoing treatment of PMMA granulomas of the nose at a private clinic from January, 2015, to January, 2021. A short-pulsed neodymium-YAG (Nd:YAG) laser was applied intranasally or directly by cutaneous incision in the granulomas. Laser-tissue interaction heats the alloplastic material, fragments the product and creates cleavage paths, thereby facilitating the removal of PMMA, either by intercartilaginous removal or aspiration. RESULTS: Twenty-seven patients were included in the study. All had a history of PMMA injection in the nose. All patients were treated with an intralesional pulsed 1064nm Nd:YAG laser. The material removed after laser-tissue interaction was sent for histopathological examination; this showed the presence of microparticles of exogenous material compatible with PMMA. The partial removal of the alloplastic material was shown to be effective in all cases. One patient developed a small blister in the nasal dorsum. Follow-up ranged from six to 47 months. CONCLUSIONS: The use of intralesional Nd:YAG laser for the treatment of PMMA granulomas on the nose proved to be an effective and safe procedure with improvement of nasal shape, without compromising respiratory function. This technical option represents yet another alternative in the treatment of PMMA granuloma complications. J Drugs Dermatol. 2021;20(11): 1161-1166. doi:10.36849/JDD.6550.

Excess, unwanted fat in submental and other body areas has been a focus of new modalities in aesthetics. Invasive and, more recently, non-invasive modalities for removal of unwanted fat have been on an increase. ATX-101 (deoxycholic acid injection) is the only injectable drug approved in the United States and Canada for reduction of moderate or severe submental fat in adults, with ongoing trials testing its efficacy in body contouring and lipomas. It has proven efficacy in submental fat reduction with a good safety profile. This article reviews the pharmacology, mechanism of action, clinical effects and adverse effects of ATX-101. It emphasizes on careful patient selection and advises on appropriate volume administration, number of treatments, and injection technique. The literature research includes peer-reviewed articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) till December 2019 and reference lists of respective articles. Only articles published in English language were included. J Drugs Dermatol. 2021;20(11):1169-1173. doi:10.36849/JDD.3936.

BACKGROUND: Port-wine stain (PWS) is a congenital vascular malformation affecting 0.3–0.5% of normal population. These characteristic lesions arise due to the interplay of vascular, neural, and genetic factors. Treatment options include lasers, cosmetic tattooing, electrotherapy, cryosurgery, derma-abrasion, and skin grafting; however, none of these treatment alternatives appears to be satisfactory and is unable to provide consistent, satisfactory responses or even complete cures. Currently, laser is the treatment of choice, as it is comparatively safe and more effective than other procedures. The most commonly used modality is pulsed dye laser (PDL). The literature research includes peer-reviewed articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) to January 2020 and reference lists of respective articles. Only articles published in English language were included.
