Onicomadesis asociada a la enfermedad de boca, mano, pie / Onychomadesis associated to mouth, hand, and foot disease

Introducción: la onicomadesis es el desprendimiento completo y espontáneo de la uña desde su extremo proximal, sin dolor o inflamación, consecutivo a la detención mitótica de la matriz ungular que conlleva a un cambio de su función. Objetivo: describir una serie de casos de onicomadesis atendidos en la consulta de Dermatología del Hospital Pediátrico Docente del Cerro, entre noviembre y diciembre del año 2017, después de presentar un cuadro clínico compatible con enfermedad boca, mano, pie, con la finalidad de contribuir al conocimiento de esta patema. Presentación de los casos: las edades estuvieron comprendidas en un rango entre 1 y 12 años, con solo 3 pacientes correspondientes al sexo masculino y solo uno con el color de la piel negra. Los días previos al padecimiento de la enfermedad boca, mano, pie se enmarcan entre 15 y 47 días de haber tenido los síntomas que indujeron al diagnóstico del citado morbo. El estudio virológico se efectuó en dos pacientes con presencia del Coxsackie A6. La evolución resultó satisfactoria en todos los casos. Conclusiones: los hallazgos, en general, coinciden con los mencionados en la literatura. Todos los pacientes presentaron semanas anteriores signos y síntomas compatibles con enfermedad boca, mano, pie. Es necesario orientar a los padres de los enfermos con este morbo, la posibilidad de la ocurrencia de onicomadesis como complicación, cuyo tratamiento es sintomático, seguido de buen pronóstico, para evitar la ansiedad familiar y los gastos de recursos innecesarios(AU)

Introduction: onychomadesis is the total and spontaneous detachment of the nail from its proximal end, without pain or inflammation, and following the mitotic halting of the nail matrix that leads to a change in its function. Objective: to describe a series of cases of onychomadesis attended in the Dermatology clinic of the Pediatric Teaching Hospital of Cerro, in the period of November to December of 2017, after presenting clinical manifestations compatible with mouth, hand, and foot disease, and in order to contribute to the knowledge of this pathology. Presentation of cases: ages were among 1 and 12 years old, with only 3 patients corresponding to the male sex and only one with black skin. The days before presenting symptoms of mouth, hand, and foot disease were between 15 and 47 days after having the symptoms that led to the diagnosis of the aforementioned disease. The virological study was carried out in two patients with the presence of Coxsackie A6. The evolution was satisfactory in all cases. Conclusions: in general the findings coincide with those mentioned in the literature. All patients presented previous signs and symptoms compatible with mouth, hand, and foot disease in the previous weeks. It is necessary to guide the parents of patients with this disease on the possibility of the onychomadesis occurrence as a complication, whose treatment is symptomatic, followed by a good prognosis to avoid family anxiety and the expense of unnecessary resources(AU)

Correlation between nailfold capillaroscopic findings and presence of interstitial lung disease in systemic sclerosis patients / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the correlation between nailfold capillaroscopic (NC) findings and the presence of interstitial lung disease (ILD) in systemic sclerosis (SSc) patients.@*METHODS@#We retrospectively involved 71 SSc patients, 45 patients with ILD. NC was performed in all the patients according to the standard method. The NC findings were semi-quantitatively scored, including enlarged and giant capillaries, hemorrhages, loss of capillaries, avascular areas, ramified/bushy capillaries and disorganization of the vascular array. The demographic and clinical data collected were gender, age, presence/absence of Raynaud phenomenon (RP), duration of RP, serological acute phase reactants and antibodies, presence of ILD (also evaluated the CT score for ILD) and pulmonary function parameters.@*RESULTS@#Among the 71 patients, the frequency of the women was 91.5%, the mean age was (52.59±12.77) years, and disease duration was (3.00±6.00) years. NC changes of the scleroderma pattern were observed in 90.1% patients. There were 45 patients with ILD and 26 patients without ILD. The patients with ILD had significantly higher loss of capillaries score [0.50 (1.03) vs. 0.00 (0.43), P=0.003], avascular area score [0.75 (1.24) vs. 0.25 (0.83), P=0.006] and ramified/bushy capillaries score [0.33 (0.88) vs. 0.13 (0.25), P=0.006] compared with those without ILD. Moreover, ramified/bushy capillaries score together with diffused SSc were independent risk factors for the presence of ILD. And the score of giant capillaries were significantly lower in the patients with more severe ILD group [0.25 (0.94) vs. 0.00 (0.28), for the mild and severe ILD groups respectively, P=0.019]. There was no statistically significant difference between the two groups with respect to the scores of enlarged capillaries, hemorrhages, or disorganization of the vascular array.@*CONCLUSION@#Capillary deletion and severe deformity in NC were associated with the presence of ILD in SSc patients. And patients with less giant capillaries had more severe ILD involvement. These indicated that NC maybe a useful tool to evaluate ILD in SSc.

Syndrome in question: antisynthetase syndrome (anti-PL-7)

Abstract: Antisynthetase syndrome is a rare autoimmune disease characterized by interstitial lung disease and/or inflammatory myositis, with positive antisynthetase antibodies (anti-Jo-1, anti-PL-7, anti-PL-12, ZO, OJ, anti-KE or KS). Other symptoms described include: non-erosive arthritis, fever, Raynaud's phenomenon, and "mechanic's hands." The first therapeutic option is corticotherapy, followed by other immunosuppressants. The prognosis of the disease is quite limited when compared to other inflammatory myopathies with negative antisynthetase antibodies.

Posible asociación autoinmune entre síndrome de Laugier-Hunziker y síndrome de Sjögren: reporte de un caso y revisión de la literatura / Laugier-Hunziker syndrome in a patient with Sjögren’s syndrome: report of one case

Laugier-Hunziker syndrome is a rare benign idiopathic condition characterized by acquired macular pigmentation of lips and buccal mucosa, often accompanied with melanonychia. The main concern with this condition is to rule out other differential diagnosis with systemic repercussions and similar hyperpigmentation patterns, such as Peutz-Jeghers syndrome, adrenal insufficiency and melanoma. We report a 58-year-old female with a 20-year history of Sjögren’s syndrome, presenting with melanonychia and hyperpigmentation in the buccal mucosa. She had no relevant medication history and is a non-smoker. The patient denied any other symptoms. The histopathology confirmed the diagnosis of Laugier-Hunziker syndrome.

Psoriasis y alopecia areata con traquioniquia concurrente en una paciente pediátrica con síndrome de Turner / Coexistence of psoriasis, and alopecia areata with trachyonychia in a pediatric patient with Turner Syndrome

El síndrome de Turner es un trastorno genético caracterizado por anomalías del cromosoma X. Se ha descrito en asociación con muchas enfermedades autoinmunitarias y con dermatosis como psoriasis, vitiligo y alopecia areata. La traquioniquia se caracteriza por el aspecto opaco irregular de la lámina ungueal de las 20 uñas. Puede manifestarse en forma idiopática o puede estar asociada con otras dermatosis. En este documento, presentamos el caso de una niña de seis años de edad con síndrome de Turner y diagnóstico de psoriasis, alopecia areata y traquioniquia, y quisiéramos remarcar una posible relación entre estas enfermedades.

Turner syndrome is a genetic disorder characterized by abnormalities of the X chromosome. An association with many autoimmune diseases is described as well as skin diseases such as psoriasis, vitiligo and alopecia areata. Trachyonychia is characterized by irregular opaque appearance on the nail plate of all 20 nails. It may be idiopathic or it can be associated with other dermatological diseases. Herein, we present a 6 years old girl with Turner syndrome who had diagnoses of psoriasis, alopecia areata and trachyonychia and we would like to draw attention to the possible relationship between these diseases.
