RESUMO
Trace elements (microminerals) play a role in many physiological functions, including hormone production and cellular growth. However, their importance in diagnosing and treating dermatologic disease has not been well examined. In this review, we discuss the functions, sources, and recommended requirements of each micromineral. In addition, we analyze the systemic and dermatological manifestations associated with micromineral imbalances. The pathogenesis of genodermatoses, such as Wilson disease, Menkes disease, acrodermatitis enteropathica, and allergic dermatitis, are also discussed. Included are studies examining the potential therapeutic role of zinc, selenium, and copper in inflammatory diseases, skin cancer, and photoaging.

BACKGROUND: Zinc is mainly absorbed in the duodenum and proximal jejunum, which are removed during pancreaticoduodenectomy (PD). Little is known about the adverse oral events and skin disorders caused by zinc deficiency after PD. Herein, we reviewed studies on the development of zinc deficiency after PD and reported about a patient with zinc deficiency after PD who required home intravenous zinc replacement. CASE PRESENTATION: A 73-year-old woman with glossitis, taste disorder, and acrodermatitis enteropathica-like eruption on her fingers presented to the Division of Dentistry and Oral Surgery 69 days after PD. Her serum zinc level markedly decreased to 30 µg/dL. Oral zinc administration was inadequate to treat hypozincemia after PD; therefore, multi-trace elements were injected intravenously during readmission. Her serum zinc levels recovered, and her lesions gradually improved. Furthermore, a central venous port was implanted to maintain normal serum zinc levels, and she continued self-injecting zinc at home. CONCLUSIONS: Zinc deficiency after PD rarely occurs. The clinical oncologist community, including dentists responsible for the oral care of cancer patients, should be aware of the oral adverse events, such as dysgeusia, glossitis, and oral pain, associated with zinc deficiency after cancer surgery and that induced by chemotherapy or head and neck radiation therapy.

Acrodermatitis enteropathica (AE) is an acquired or inborn (congenital) disorder of zinc metabolism that leads to zinc deficiency. The congenital form typically presents in infants during the first few months of life when they are weaned from breast milk, presenting even earlier in those who are formula fed. Acquired deficiency may be seen at any age. The characteristic clinical features of AE include erythematous, dry, scaly papules and plaques that may evolve into crusted, erosive, pustular lesions. These lesions typically are distributed in an acral and periorificial pattern and are associated with alopecia and diarrhea. Evidence-based recommendations are sparse but generally indicate 3 mg/kg/d of oral zinc supplementation for both congenital and acquired AE. Appropriate dosing helps to avoid acute zinc toxicity involving nausea and vomiting. We report a case of a 3-month-old female infant with acquired AE who was successfully treated with zinc supplementation over the course of 3 weeks.

A 3-month-old, full term female infant, adequate for gestational age, and exclusively breastfed, was admitted with a 10 day history of generalised scaling erythematous dermatitis, affecting the face (perinasal, nasolabial folds and periauricular), acral and intertriginous areas, with irritability and failure to thrive. Her mother had been treated with isoniazid since the third trimester because of family contact with tuberculosis. Based on a diagnosis of suspected impetiginised eczema, the infant was treated with flucloxacillin and prednisolone, and maternal isoniazid was suspended, with no improvement. Investigations found low serum zinc levels in the infant (33 µg/dL; normal range (NR) >60 µg/dL), normal plasma zinc levels in the mother (111.3 µg/dL; NR 68-120 µg/dL) and lower than the normal range of zinc levels in breast milk (270µg/L; NR 1000-2500 µg/L), suggesting acrodermatitis caused by zinc deficiency. Oral zinc supplementation (3 mg/kg/day) was started with a marked improvement in skin lesions, as well as good weight gain. At the age of 6 months, after food diversification, supplementation was suspended, without any recurrence of symptoms.

La acrodermatitis enteropática (AE) es una genodermatosis autosómica recesiva causada por la mutación del gen responsable de codificar a la proteína transportadora de Zinc (Zn) SLC39A4. A pesar de ser una rara enfermedad es de fácil manejo y gran relevancia clínica. Se caracteriza por la siguiente tríada: dermatitis acral y periorificial, diarrea y alopecia. Comunicamos un caso de presentación atípica en una lactante de 6 meses de edad con lesiones periorificiales y ampollas acrales que resolvió rápidamente con la terapia suplementaria con Zinc (AU)
Enteropathic acrodermatitis is an autosomal recessive genodermatosis caused by the mutation of the gene responsible for encoding the Zinc transporter protein SLC39A4. Despite being a rare disease, it is easy to manage and of great clinical relevance. It is characterized by the following triad: acral and periorificial dermatitis, diarrhea and alopecia. We report a case of atypical presentation in an almost 6-month-old infant with periorificial lesions and acral blisters that quickly resolved with supplemental Zinc therapy (AU)

Well-known causes of zinc deficiency, also referred to as acrodermatitis enteropathica (AE), include defects in intestinal zinc transporters and inadequate intake, but a rare cause of acquired zinc deficiency discussed here is an iatrogenic nutritional deficiency caused by parenteral nutrition administered without trace elements. While zinc-depleted parenteral nutrition causing dermatosis of acquired zinc deficiency was first reported in the 1990s, it is now again relevant due to a national vitamin and trace element shortage. A high index of suspicion may be necessary to diagnose zinc deficiency, particularly because early clinical findings are nonspecific. We present this case of acquired zinc deficiency in a patient admitted to a pediatric intensive care unit for respiratory distress and atypical pneumonia, who subsequently developed a severe bullous eruption due to iatrogenic zinc deficiency but was treated effectively with enteral and parenteral zinc supplementation, allowing for rapid re-epithelialization of previously denuded skin.

Acrodermatitis enteropathica (AE) is a rare disease characterised by a failure in intestinal zinc absorption, which results in a host of symptoms that can ultimately lead to death if left untreated. Current clinical treatment involves life-long high-dose zinc supplements, which can introduce complications for overall nutrient balance in the body. Previous studies have therefore explored the pharmacological treatment of AE utilising metal ionophore/transport compounds in an animal model of the disease (conditional knockout (KO) of the zinc transporter, Zip4), with the perspective of finding an alternative to zinc supplementation. In this study we have assessed the utility of a different class of zinc ionophore compound (zinc diethyl bis(N4-methylthiosemicarbazone), Zn-DTSM; Collaborative Medicinal Development, Sausalito, CA, USA) to the one we have previously described (clioquinol), to determine whether it is effective at preventing the stereotypical weight loss present in the animal model of disease. We first utilised an in vitro assay to assess the ionophore capacity of the compound, and then assessed the effect of the compound in three in vivo animal studies (in 1.5-month-old mice at 30 mg/kg/day, and in 5-month old mice at 3 mg/kg/day and 30 mg/kg/day). Our data demonstrate that Zn-DTSM has a pronounced effect on preventing weight loss when administered daily at 30 mg/kg/day; this was apparent in the absence of any added exogenous zinc. This compound had little overall effect on zinc content in various tissues that were assessed, although further characterisation is required to more fully explore the cellular changes underlying the physiological benefit of this compound. These data suggest that Zn-DTSM, or similar compounds, should be further explored as potential therapeutic options for the long-term treatment of AE.

Zinc deficiency is an uncommon condition, known to occur in two forms: inherited type, known as Acrodermatitis enteropathies and the acquired type. Cutaneous clinical manifestations observed include characteristic dermatitis on acral, periorificial, and anogenital areas through an unknown mechanism. The patient had a combination of causes which lead to a state of zinc deficiency. We are presenting it due to the rarity of acquired acrodermatitis in patients of gastrointestinal tuberculosis and renal transplant recipients. We emphasize the awareness about this condition, especially in resource-poor settings, where serum zinc levels may not be available, and a trial of oral zinc may be given.

Zn is essential for growth and development. The bioavailability of Zn is affected by several factors such as other food components. It is therefore of interest, to understand uptake mechanisms of Zn delivering compounds to identify ways to bypass the inhibitory effects of these factors. Here, we studied the effect of Zn amino acid conjugates (ZnAAs) on the bioavailabilty of Zn. We used Caco-2 cells and enterocytes differentiated from human induced pluripotent stem cells from a control and Acrodermatitis enteropathica (AE) patient, and performed fluorescence based assays, protein biochemistry and atomic absorption spectrometry to characterize cellular uptake and absorption of ZnAAs. The results show that ZnAAs are taken up by AA transporters, leading to an intracellular enrichment of Zn mostly uninhibited by Zn uptake antagonists. Enterocytes from AE patients were unable to gain significant Zn through exposure to ZnCl2 but did not show differences with respect to ZnAAs. We conclude that ZnAAs may possess an advantage over classical Zn supplements such as Zn salts, as they may be able to increase bioavailability of Zn, and may be more efficient in patients with AE.

Acrodermatitis enteropathica syndrome (AE) is a clinical entity that results in severe zinc deficiency. It can be genetic or acquired. Acquired AE has been reported in patients with chronic liver disease, malabsorption syndrome, sickle cell anemia, and chronic renal failure. We present a kidney transplant recipient with skin rash and watery diarrhea. The patient had low serum zinc levels, which quickly resolved after zinc supplementation. Skin biopsy showed cytoplasmic pallor and vacuolization and ballooning degeneration of keratinocytes within the superficial epidermis, which may have led to confluent necrosis of keratinocytes. Large amounts of keratinosome-derived lamellae were found in the intercellular spaces in the keratinized area, probably related to disturbance of keratinosome metabolism due to zinc deficiency.

Zinc deficiency in patients with coeliac disease (CD) may result either from cumulative loss of insoluble zinc complexes or impaired zinc absorption because of damaged intestinal epithelial cell membrane. Zinc deficiency in CD is mild to moderate, though severe deficiency can occur in refractory or chronic CD cases with poor response to gluten-free diet (GFD). A boy aged 19 months presented with persistent diarrhoea, was diagnosed with CD, and developed severe zinc deficiency with acrodermatitis enteropathica-like disease while on GFD and zinc supplementation.

INTRODUCTION: Paraviral exanthems are skin diseases suspected to be caused by viruses, with a single virus-exanthem relationship not universally accepted. Although most paraviral exanthems are self-remitting, accurate diagnoses are important as some patients might develop complications. Some of the differential diagnoses might cause serious complications, and some paraviral exanthems might lead to complications for at-risk groups such as pregnant women. Moreover, some paraviral exanthems might be symptomatic such as the development of severe pruritus, with relief of such being crucial in the plan of management. Patients and carers of patients should also be counselled regarding the aetiologies, clinical features, and prognoses of the exanthems concerned. AREAS COVERED: We covered the clinical manifestations and managements of pityriasis rosea, pityriasis lichenoides, and Gianotti-Crosti syndrome. Expert Commentary: Most patients with pityriasis rosea do not need any active intervention. Symptomatic relief of the pruritus would be adequate. For patients with pityriasis rosea that are serious, extensive, or causing severe impacts of their quality of life, oral acyclovir could be considered. For pityriasis lichenoides, managements would be depending on the type of the exanthem such as the acute form (pityriasis lichenoides et varioliformis acuta, also known as Mucha Habermann disease) the chronic form (pityriasis lichenoides chronic Juliusberg's disease), and the febrile ulceronecrotic Mucha-Habermann disease, which is a complication of the acute form. The management of Gianotti-Crosti syndrome is mainly symptomatic. The need for long-term follow-up for chronic complications of the underlying viral infections is still controversial.

Nutritional deficiency is rare in developed countries, but can be acquired from decreased nutrient intake, reduced absorption, and increased gastrointestinal excretion. We report a patient with acquired acrodermatitis enteropathica (AE) who exhibited low plasma zinc levels and concurrent nutritional deficiencies (pyridoxine, selenium and fatty acids). Our patient had undergone Roux-en-Y gastric bypass 13 years prior to presentation. The rash, consistent with AE clinically and histologically, nearly resolved one week after starting IV zinc supplementation, total parenteral nutrition, and micronutrient supplements. This case highlights the importance of long-term post-operative follow-up for gastric bypass patients who are at high risk for micronutrient and macronutrient deficiencies and illustrates the potential for rapid improvement with IV supplementation.

Acrodermatitis enteropathica is a rare autosomal recessive disease characterized by pink scaly plaques and erosions in the periorificial and acral regions. A mutation in a gene responsible for zinc transport results in significant zinc deficiency in individuals lacking oral supplementation. We present a female infant with acrodermatitis enteropathica with crusting of the periorificial regions along with perineal plaques. A delay in diagnosis and treatment led to the development of pronounced painful acral bullae. Although plaques and erosions in the periorificial and acral regions are most commonly observed, bullae should also be considered in the spectrum of clinical manifestations of acrodermatitis enteropathica. The rare bullous variant of acrodermatitis enteropathica can be distinguished histologically.
