Lesiones cutáneas asociadas al uso de bombas de insulina y sistemas de monitoreo: un problema desafiante / Insulin pumps and glucose monitors related cutaneous lesions: a challenging problem

Los cuidados actuales de la diabetes incluyen altos niveles de tecnología y los pacientes utilizan diferentes dispositivos que pueden ayudar en su control metabólico, pero pueden impactar negativamente en su piel. Sensores de glucosa como el Freestyle, Dexcom, el Enlite de Medtronic y los sistemas de infusión continua de insulina contienen diferentes productos químicos que están en contacto directo con la piel del paciente y pueden causar una dermatitis irritativa o de contacto alérgica. Las lesiones incluyen eczema, prurito, heridas, cicatrices y cambios en la pigmentación de la piel. Los productos químicos involucrados que pueden ocasionarlas son el isobornil acrilato, N, N- dimetilacrilamida, etil cianoacrilato y colophonium, forzando a los pacientes a cambiar los sitios de infusión, el set de infusión o el sensor mismo más pronto de lo esperado, para reducir el nivel de daño en la piel. Existe gran número de productos que permiten proteger la piel y reducir el contacto de la piel con la cánula de la bomba o el sensor. Para reducir o prevenir el daño existen productos como cremas o spray y parches de hidrocoloide que actúan como barrera y existen técnicas para aplicar y retirar cuidadosamente los parches y adhesivos de los dispositivos. Una vez que las lesiones se han producido, el tratamiento incluye pomadas y a veces corticoides tópicos y/o antibióticos. Para prevenir o reducir el daño de la piel asociado al sensor y uso de la bomba de insulina, la industria que los produce debería incluir la información en relación a los productos químicos incluidos en cada dispositivo.

Diabetes care nowadays includes a high level of technology and patients use different devices which can help them in their glycemic control, but can have a negative impact on their skin. Glucose sensors such as Freestyle, Dexcom, Medtronic Enlite and also continuous subcutaneous insulin infusion systems contain different chemical products which are in direct contact with the patient's skin and can cause irritative or allergic contact dermatitis. Lesions include eczema, pruritus, wounds, scars and changes in skin pigmentation. The chemical products which can induce them are isobornyl acrylate, N, N- dimethylacrylamide, ethyl cyanoacrylate and colophonium, forcing patients to change the infusion site, set or the sensor itself, earlier than expected, in order to reduce the level of skin damage. There are a number of products which can protect the skin and reduce it's contact with the pump cannula or the sensor. To reduce or prevent damage, we have products such as barrier cream or spray films and hydrocolloid blister plasters and actions such as careful application and removal of device's patches and adhesives. Once lesions are established, treatment includes ointments and sometimes topical steroids and/ or antibiotics. In order to prevent or reduce skin damage related to sensor and insulin pump use, the manufacturers should include the information related to the chemicals included in each device.

Coinfección leishmania infantum, VIH e histoplasma capsulatum: manifestaciones dermatológicas / Leishmania infantum, HIV and hystoplasma capsulatum coinfection: dermatologic manifestations

La coinfección Leishmania/VIH es frecuente y por lo general son casos de leishmaniosis visceral (LV), sin embargo, Leishmania infantum, el agente etiológico, también puede causar formas cutáneas en pacientes VIH-positivos. Los parásitos llegan a la piel por difusión, en una nueva infección o reactivación de una infección latente. Existen técnicas moleculares que confirman el diagnóstico y caracterizan a la especie. En estos pacientes también se presenta como infección oportunista la histoplasmosis, reconocida como marcador de SIDA y causada por Histoplasma capsulatum. En este trabajo describimos un caso de coinfección SIDA, histoplasmosis y LV asociado a lesiones cutáneas. Paciente de sexo masculino, adulto, residente en J.A. Saldívar, VIH positivo (2010), sin tratamiento antirretroviral. En el 2012 es internado en el Instituto de Medicina Tropical (IMT) con fiebre, anemia, hepato-esplenomegalia, frotis de médula ósea y rk39 negativos para Leishmania, recibe tratamiento con Anfotericina B. En el 2013 presenta síndrome febril prolongado y en médula ósea se encuentran amastigotes de Leishmania sp. En el 2014 presenta úlceras en el rostro en las que se observan es porosmicóticos de H. capsulatum y amastigotes de Leishmania sp. Se confirma L. infantum por técnicas de biología molecular. En el caso estudiado concluimos que la presentación dérmica es causada por L. infantum, caracterizada por técnicas moleculares, eH. capsulatum que se presenta en concomitancia debido al estado inmunológico. Cabe resaltar la importancia del diagnóstico diferencial para aplicar el tratamiento correcto y además la manifestación clínica que normalmente no es asociada a esta especie de Leishmania.

Leishmania/HIV coinfection is frequent and generally they are visceral leishmaniasis cases(VL). However, Leishmania infantum, the etiological agent, could also cause cutaneousforms in HIV-positive patients. The parasites reach the skin through diffusion, a newinfection or a reactivation of a latent infection. There are molecular techniques that confirmthe diagnosis and characterize Leishmania species. These patients also present otheropportunistic infections like histoplasmosis, well known as an AIDS marker and caused byHistoplasma capsulatum. In this work, we describe one HIV/histoplasmosis/VL coinfectioncase associated to cutaneous lesions. The patient was a male, adult, coming from the city ofJ.A. Saldívar, HIV positive (since 2010), without antiretroviral treatment. He was hospitalized in 2012 at the Instituto de Medicina Tropical (IMT) with fever, anemia,hepatosplenomegaly, bone marrow smear and rK39 both negative for Leishmania. He wastreated with Amphotericin B. In 2013, he presented a prolonged febrile syndrome andLeishmania amastigotes were observed in the bone marrow. In 2014, the patient presentedulcerations on the face where H. capsulatum fungal spores and Leishmania amastigoteswere observed. L. infantum was confirmed by molecular methods. In the case under studywe can conclude that the dermal manifestation was caused by L. infantuma ccording to thecharacterization by molecular techniques, and simultaneously H. capsulatum was presentdue to his immunological status. It should be emphasized the importance of the differentialdiagnosis in order to apply the right treatment and also the uncommon clinicalmanifestation that is not associated to this Leishmania species.

Single dose amoxicillin induced toxic epidermal necrolysis A rare life threatening dermatological condition.

Toxic epidermal necrolysis is a severe cutaneous drug reaction, mainly involving skin and mucous membranes. We have presented here a case report of 16 year old female patient who was diagnosed with toxic epidermal necrolysis clinically as well as histopathologically. The patient presented with history of fever, oral cavity ulcer, skin lesions which were ill defined, erythematous macular with darker hemorrhagic centre. Skin biopsy showed full thickness necrosis of dermis, dermal-epidermal separation and paucity of upper dermal cellular infiltration. The patient was treated with intravenous immunoglobulins, low dose steroids and systemic antibiotics and the patient improved significantly. The main purpose of the case report was to emphasize that even one single dose of amoxycillin can induce a toxic epidermal necrolysis.

Intraspinal and Urogenital Abnormalities in Infants with Sacral Cutaneous Lesions

PURPOSE: Sacral cutaneous lesions, such as dimples and hairy patches, may be associated with occult spinal dysraphism and urogenital abnormalities. This study aim to delineate high risk infants who need early screening for intraspinal and urogenital abnormalities by identifying the association between cutaneous lesions and combined abnormalities. METHODS: Sacral ultrasonography was performed in 777 infants with sacral cutaneous lesions from January 2010 to July 2014. Of these, 317 infants underwent abdominal ultrasonography for urogenital abnormalities. We reviewed the patient's medical records and radiographic findings retrospectively. RESULTS: Of the 777 infants, abnormal intraspinal findings such as tethered cord or meningocele were reported in 26 (3.4%). Sixteen of these 26 patients with abnormal findings underwent follow-up ultrasonography or MRI; 4 infants were diagnosed with lipomeningomyelocele through MRI, and 1 infant underwent a neurosurgical procedure. Among the 317 infants who underwent abdominal ultrasonography, 78 infants (24.6%) had congenital hydronephrosis and 8 infants (2.5%) had other urogenital abnormalities including duplication of kidney, vesicoureteral reflux, horseshoe kidney, renal cyst, or multicystic dysplastic kidney. Urogenital abnormalities were more common in patients with sacral dimples associated with hair or deviated gluteal folds than in those with simple dimples (OR 3.24 and 8.88; P=0.007 and P=0.001, respectively). CONCLUSION: Midline sacral cutaneous lesions may be associated with occult spinal dysraphism and urogenital abnormalities. To detect intraspinal lesions, ultrasonography is recommended for infants with sacral cutaneous lesions. Likewise, infants with sacral dimples associated with either hair or deviated gluteal folds, should be evaluated via abdominal ultrasonography to assess for combined urogenital abnormalities.

Mel e açúcar mascavo na cicatrização de feridas / Honey and brown sugar in wounds healing

O estudo teve como objetivo comparar a eficácia do mel e do açúcar mascavo na cicatrização de feridas induzidas cirurgicamente na pele de cobaias, para avaliar o tempo de cicatrização, as variações macroscópicas e microscópicas do tecido cicatricial, a contração das feridas e o grau de contaminação. Quinze cobaias da raça Abissínia, machos inteiros, de seis meses de idade e pesando entre 500 a 850 gramas, foram divididas em três grupos com cinco animais cada, nos quais foram induzidas, cirurgicamente, três feridas em cada animal com dimensão de 1,5cm² e distância entre elas de 1,5cm, na região dorsal. A ferida F1 foi tratada diariamente com mel, a ferida F2 com solução salina 0,9% (controle) e a ferida F3 com o açúcar mascavo. A eutanásia foi realizada no Grupo 1 ao sétimo dia após a cirurgia, no Grupo 2 ao décimo quarto dia e no Grupo 3 no vigésimo primeiro dia após a cirurgia, sendo as biópsias encaminhadas para avaliação histopatológica. Foram também realizados swabs das feridas em todos os grupos no terceiro e sétimo dias após a cirurgia e as amostras enviadas para a cultura e isolamento bacteriano. Concluiu-se que as feridas tratadas com o mel cicatrizaram mais rápido em relação às tratadas com o açúcar mascavo, demonstrando a maior propriedade cicatrizante do mel em relação ao açúcar mascavo.

The study aimed to compare the effectiveness of honey and brown sugar in wounds healing induced in the skin of guinea pigs, to evaluate the healing time, microscopic and macroscopic healing variations, wound contraction and contamination degree. Fifteen guinea pigs, Abyssinia breed, males, six months of age and weighing between 500 to 850 grams, were divided in three groups with five animals each. Three wounds were promoted in each animal, surgical, with 1.5cm² and 1.5cm between them, in the dorsal region. The F1 was treated, daily, with honey, F2 with saline solution 0,9% (control) and F3 with brown sugar. Euthanasia was performed in Group 1 on the seventh day after the surgery, Group 2 on the fourteenth day and the Group 3 on the twenty-first day after the surgery and the biopsies sent to histopathological evaluation. Wounds swabs were made in all groups on the third and seventh days after the surgery and the samples sent for culture and bacterial isolation. The wounds treated with honey healed faster than treated with brown sugar.

Arteriolopatía calcificante urémica / Uremic calcifying arteriopathy

La arteriolopatía calcificante urémica es una complicación poco frecuente de la enfermedad renal crónica y se asocia con elevada tasa de mortalidad. A propósito se describió el caso clínico de un hombre de 59 años de edad, con insuficiencia renal crónica terminal que se hallaba en programa de hemodiálisis convencional, en régimen de 3 veces/semana, desde el año 2007. Se le diagnosticó arteriolopatía calcificante urémica grave tras sospecha clínica y biopsia de lesiones cutáneas, con un desenlace fatal. Reconocemos que se requiere un alto índice de sospecha clínica para su diagnóstico precoz y no siempre se asocia a hiperparatiroidismo secundario grave, en su patogenia se imbrican múltiples factores

The calcifying arteriolopathy is an uncommon complication of chronic renal disease and it is associated with a high rate of mortality. Authors present the clinical case of a man aged 59 presenting with terminal chronic renal failure under a three times/week conventional hemodialysis program from 2007. He was diagnosed with a severe uremic calcifying arteriolopathy after a clinical suspicion and biopsy of cutaneous lesions with a fatal outcome. It is recognized that it is necessary a high rate of clinical suspicion for its early diagnosis and not always it is associated with a severe secondary hyperparathyroidism where multiple factors are involved in its pathogenesis

Dermatite por lambedura em bovinos no estado do Pará / Licking dermatitis in cattle in the state of Pará, Brazil

Foi estudada uma doença em 13 bovinos de 10 propriedades localizadas em seis municípios do estado do Pará, caracterizada por feridas ulcerativas da pele. A doença foi observada somente em regiões do corpo, aos quais os animais tinham acesso com a própria língua; também foi observado que os animais lambiam as feridas com freqüência. Os estudos epidemiológicos e patológicos desses casos, bem como o descarte dos diagnósticos diferenciais, permitiram concluir que se trata de dermatite por lambedura. Essas feridas sararam após a realização da contenção da cabeça dos animais, que desta maneira ficaram impossibilitados de lamber as mesmas.

A condition of 13 cattle from 10 farms in six districts in the state of Pará, Brazil, characterized by ulcerative skin wounds was studied. The lesions were observed in regions of the body to which the cattle had access with their own tongue; the animals licked the wounds frequently. Epidemiological studies, pathological findings and the differential diagnosis indicate that the dermatitis is caused by licking. The wounds healed after restraining the head of the animals that then were unable to lick themselves.

Clinical Study on Adult Onset Still's Disease / 대한피부과학회지

BACKGROUND: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease of an unknown etiology, and this is characterized by spiking fever, evanescent rash, arthritis and multiorgan involvement. OBJECTIVE: This study was conducted to better understand the clinical characteristics of patients with AOSD, and especially the cutaneous features. METHODS: We reviewed the medical records and cutaneous findings of 21 patients who were diagnosed with AOSD at our hospital from 2003 to 2009. The diagnosis of AOSD was based on the criteria proposed by Yamaguchi et al. RESULTS: Eighteen (86%) out of the 21 patients were women, and the age of onset ranged from 18 to 55 years. Fever occurred in 21 (100%) patients, skin rash in 20 (95%), arthralgia in 18 (86%), sore throat in 10 (48%) and lymphadenopathy in 7 (33%). The cutaneous features were as follows: typical maculopapular eruption (70%), urticaria (10%), petechia and purpura (10%), persistent plaques and linear pigmentation (5%) and acne-like lesions (5%). The most common sites of skin lesion were the trunk (80%) and thighs (80%). The histopathologic findings of 9 patients showed non-specific chronic inflammation with a perivascular mononuclear preponderance in 6 patients, and the others were consistent with urticaria or leukocytoclastic vasculitis. CONCLUSION: The various cutaneous features of this study suggest that dermatologists should consider AOSD in any patient with cutaneous eruption associated with fever and arthralgia.

Lesões de pele causadas pelos espinhos de Mimosa pudica (Leg. Mimosoideae) nos membros de bovinos e ovinos no estado do Pará / Cutaneous lesions of the legs caused by the thorns of Mimosa pudica (Leg. Mimosoideae) in cattle and sheep in the State of Pará

Foi estudada uma doença em bovinos e ovinos caracterizada por lesões ulcerativas e granulomatosas da pele dos membros. Os estudos epidemiológicos e patológicos permitiram concluir que essas lesões são causadas pelos espinhos de Mimosa pudica (Leg. Mimosoideae). A doença foi observada somente em pastagens acentuadamente infestadas e os animais se recuperaram rapidamente após retirados destes pastos. Nos ovinos as lesões atingiam partes mais altas dos membros do que nos bovinos, devido ao seu menor porte.

A condition of cattle and sheep characterized by ulcerous and granulomatous skin lesions of the legs was studied. Epidemiological data and the nature of the lesions indicate that they are caused by the thorns of Mimosa pudica (Leg. Mimosoideae). The disease was observed only in pastures largely infested by the plant, and animals recover quickly when moved from them.

Clinical Patterns of Cutaneous Lesions on the Legs in Patients with Cutaneous Polyarteritis Nodosa / 대한피부과학회지

BACKGROUND: Cutaneous manifestations of vasculitis can be seen as pleomorphic lesions; purpura, erythema, nodule, bulla, ulcer and so on. In cases of polyarteritis nodosa (PAN), cutaneous presentations of small artery pathology may be seen in about one fourth among those patients with systemic form of PAN, and in all cases of cutaneous form subset. OBJECTIVE: To examine the pattern or morphology of cutaneous lesions found in the skin (especially on the lower legs) among Korean patients with cutaneous form of PAN. Patients AND METHODS: Eight patients with diagnosis-confirmed cases of cutaneous PAN were examined regarding the patterns of cutaneous lesions, as well as possible local symptoms, distributions, duration, and any positive findings in laboratory examinations and systemic review. RESULTS: Clinical patterns of cutaneous lesions observed in the lesional areas among those 8 patients were mottled or atypical reticular erythema (5 cases), subcutaneous nodules (3 cases), scattered erythematous patch (3 cases), ecchymotic erythematous patch (3 cases) and superficial ulcer (1 case). Tenderness was detected at the nodular lesions; predilection site were shin and calf areas; a few laboratory abnormalities and systemic symptoms were found regardless of the duration of skin lesions. CONCLUSION: Common clinical patterns of cutaneous lesion recognized with 8 patients of cutaneous PAN were mottled/atypical reticular erythemas, subcutaneous nodules, erythematous/ecchymotic patches, and these in all cases were seen at the lower legs. In patients with each different clinical presentation, there were no relevancies between the duration and severity of the disease.
