Abstract Lymphangioma is a rare and understudied pathology that is usually detected in the first decade of life, and its appearance in adults is rare. This report details a 51-year-old man with morbid obesity who presented, for the last eight months, multiple asymmetric tumor lesions with extension to the scrotal region. The diagnosis of circumscribed lymphangioma with associated infection was confirmed. This case report demonstrates an unusual presentation of the characteristics of the lymphangioma that are seldom described in the literature.

Resumo O diagnóstico e tratamento da depressão em pacientes com doença de Parkinson (DP) é inadequado, frequentemente contribuindo para a redução da qualidade de vida, progressão rápida da doença, maior comprometimento cognitivo e aumento da carga de cuidado aos familiares de pacientes com DP. Objetivo: Determinar os fatores associados à depressão na DP e examinar a frequência de sintomas depressivos entre pacientes com DP. Métodos: Este estudo foi um estudo observacional, analítico, multicêntrico, de uma coorte transversal conduzida entre julho de 2016 e maio de 2017. Os pacientes com DP foram recrutados em clínicas de neurologia em Lima, Peru. Todas as análises estatísticas foram realizadas por meio de estatística descritiva. Análises de regressão logística bivariada e multivariada foram calculadas usando STATA. Resultados: Dos 124 pacientes (idade média: 68,7 anos; 58% homens) incluídos no estudo, 60,5% (75/124) apresentaram sintomas de depressão; apenas 20% (25/124) receberam antidepressivos. Os fatores associados à depressão na DP incluíram: desemprego, quedas, congelamento da marcha, movimentos involuntários micrografia, postura inclinada, hiposmia, distúrbios do movimento no sono, progressão rápida da doença e uso de inibidores da MAO. Além disso, houve diferenças estatisticamente significativas encontradas em: duração da doença, escores nas escalas UPDRS e MMSE, estágio Hoehn e Yahr (HY) e tempo de duração da L-dopa entre os pacientes com DP, entre aqueles com e sem sintomas depressivos. Conclusão: Fatores associados a sintomas depressivos em pacientes com DP foram hiposmia, rápida progressão da doença, uso de L-dopa e uso de IMAOs. A frequência de sintomas depressivos em pacientes com DP é alta; o diagnóstico precoce e o tratamento imediato são necessários para melhorar a qualidade de vida e o ambiente familiar.

Abstract The diagnosis and treatment of depression in patients with Parkinson’s disease (PD) is inadequate, often contributing to a reduced quality of life, rapid disease progression, higher cognitive impairment, and an increased burden of care for family members of patients with PD. Objective: To determine the factors associated with depression in PD and to examine the frequency of depressive symptoms among patients with PD. Methods: This study was an observational, analytical, multicenter study of a cross-sectional cohort, conducted between July 2016 and May 2017. PD patients were recruited from neurology clinics in Lima, Peru. All statistical analyses were performed using descriptive statistics. Bivariate and multivariate logistic regression analyses were calculated using STATA. Results: Out of 124 patients (average age: 68.7 years; 58% males) included in the study 60.5% (75/124) presented with symptoms of depression; only 20% (25/124) received antidepressants. Factors associated with depression in PD included: unemployment, falls, freezing of gait, involuntary movements micrographia, stooped posture, hyposmia, movement disorders in sleep, rapid disease progression, and the use of MAOIs. Furthermore, statistically significant differences were found in disease duration, UPDRS and MMSE scores, Hoehn and Yahr (HY) stage, and length of time taking L-dopa between PD patients with and without depressive symptoms. Conclusion: Factors associated with depressive symptoms in patients with PD were hyposmia, rapid progression of the disease, the use of L-dopa, and use of MAOIs. The frequency of depressive symptoms in patients with PD is high; early diagnosis and prompt treatment are needed to improve their quality of life and the family environment.

Gaucher disease is an autosomal recessive lysosomal storage disorder characterized by deficiency of beta-glucosidase that would lead to the accumulation of glucosylceramide mainly in cells of the mononuclear phagocytic system causing systemic effectations. We present a patient of twenty years who is suffering from chronic pain in the left hypochondrium with episodes of bleeding for 3 years and sensation of thermal rise, physical examination revealed jaundice and massive splenomegaly, without neurological involvement. Severe osteoporosis, pancytopenia, and the presence of portal vein thrombosis with cavernomatous transformation complicated by portal biliopathy simulating a klatskin tumor, marrow and enzymatic studies were compatible with Gaucher disease, were shown as unexpected findings. he received treatment with imiglucerase, following up. It is a rare case, of great interest, heterogeneity in its clinical manifestations and unpublished by its complication, constituting a challenge to reach its diagnosis of this orphan disease.

La enfermedad de Gaucher, es un trastorno autosómico recesivo de depósito lisosomal que se caracteriza por deficiencia de la beta-glucocerebrosidasa que lleva a la acumulación de glucosilceramida principalmente en células del sistema fagocítico mononuclear causando afectaciones sistémicas. Se presenta paciente varón de 20 años que cursa con dolor crónico en hipocondrio izquierdo con episodios de sangrados desde hace 3 años y sensación de alza térmica, al examen físico se identificó ictericia y esplenomegalia masiva, sin afectación neurológica. Como apoyo al diagnóstico se mostró osteoporosis severa, pancitopenia y como hallazgo inesperado la presencia de trombosis de vena porta con transformación cavernomatosa complicada con biliopatía portal simulando un tumor de klatskin, los estudios de médula y enzimáticos eran compatibles con enfermedad de Gaucher, por lo cual recibió tratamiento con imiglucerasa realizando seguimiento. Es un caso poco frecuente, de gran interés, heterogeneidad en sus manifestaciones clínicas e inéditas por su complicación, constituyendo un desafío llegar a su diagnóstico de esta enfermedad huérfana.

Objective: To determine the frequency, characteristics and associated factors with the Burnout Syndrome (BS) in medical students. Material and methods: This is a cross-sectional study. Five-hundred and eighty three (583) medical students doing clinical sciences courses having hospital training periods in Lima, Ica, Junín, Lambayeque and Ucayali were surveyed. The presence of BS was determined using the Maslach Burnout Inventory (MBI) in its validated Spanish version, and also the socio-demographic characteristics included in the instrument. Results: Gender distribution was similar (50.6% were male), also 16.5%, 47.7% and 35.3% of the students reported having emotional exhaustion, severe depersonalization and low personal accomplishments, respectively, as defined by the MBI. Also, a significant association was found between BS and being overweight (Prevalence ratio (PR)= 1.57; 95% confidence interval (95% CI)= 1.14 to 2.14); obese (PR= 2.68; 95% CI= 1.75 to 4.11), having chronic disease (PR= 1.84; 95% CI= 1.38 to 2.45), smoking (PR= 1.41; 95% CI= 1.76 to 2.28) drinking alcohol (PR= 1.46; 95% CI= 1.10 to 1.95) and studying in a province university (PR= 1.20; 95% CI= 1.05 to 1.36). Conclusion: BS occurs in those who suffer from a chronic illness, smoke, drink alcohol, and study in a province university
