ABSTRACT

Resumen Histológicamente, los tumores testiculares de células germinales pueden clasificarse como tumores de tipo no seminoma y seminoma. De este último se reconocen tres variantes: "anaplásica", "espermatocítica" y "clásica", la cual puede ser gonadal o extragonadal. En este subtipo el tumor tiene origen en las células germinales, aunque no inicia en las gónadas sino en otras regiones anatómicas como el mediastino o el retroperitoneo. Presentamos el caso de un paciente de 19 años quien inicialmente presentó un cuadro clínico compatible con síndrome de vena cava superior y trombosis yugular. El diagnóstico de la neoplasia se obtuvo mediante biopsia por toracotomía.


Abstract Histologically, germ cell testicular tumors can be classified as nonseminoma and seminoma tumors. Of the latter, three variants are recognized: "ana plastic", "spermatocytic" and "classical", which may be gonadal or extrago nadal. In this subtype, the tumor originates in the germ cells, although it does not start in the gonads but in other anatomical regions such as the mediastinum or the retroperitoneum. We present a case of a 19-year-old patient who initially presented clinical sintomatology compatible with su perior vena cava syndrome and jugular thrombosis. The diagnosis of the neoplasm was obtained by thoracotomy biopsy.

ABSTRACT

PURPOSE: Diagnosis of tuberculous uveitis (TBU) is often challenging and is usually made after excluding other causes of uveitis. We analysed the characteristics of TBU and variables associated with visual outcome. METHODS: A retrospective, observational analysis was performed in patients with presumptive TBU who were started on specific TB treatment between January 2006 and June 2016. Demographic, clinical, radiological, analytical and ophthalmic examination variables were studied. After completing TB treatment, a follow-up of at least 9 months was performed. A univariate and logistic regression analysis was applied to identify the variables associated with visual acuity and recurrences of uveitis. RESULTS: Forty affected eyes of 24 individuals were identified; 79% of patients were diagnosed during the last 3 years of the study period. Median delay from onset of symptoms to diagnosis was 12 weeks. Loss of visual acuity was the most frequent symptom (87.5%). Posterior uveitis was the most frequent localization (72.9%); 19 patients (79.2%) presented at least one of the Gupta signs predictive of TBU, but there were no confirmed diagnoses. OUTCOME: There was improvement in visual acuity in 74.4% of the eyes, but a complete response was achieved only in 56.4%. There was recurrence in two patients. The initiation of treatment ≥ 24 weeks after onset of symptoms was significantly associated with no improvement (p = 0.026). CONCLUSION: TBU can cause permanent damage to visual acuity, particularly in patients with delayed diagnosis. A prompt initiation of systemic TB treatment is essential to improve visual prognosis.

ABSTRACT

Introducción. Un bezoar se define como un elemento no digerible atrapado en algún punto del tubo digestivo, el cual puede ser ingerido de forma intencional o accidental. El primer reporte de un bezoar en la literatura médica lo hizo Baudamant en 1779. Caso clínico. Se presenta un caso de un bezoar de plástico, un cepillo dental, como causa de pancreatitis aguda y su manejo por laparoscopia, con una revisión de la literatura. Discusión y conclusiones. Aunque los bezoares gástricos son poco frecuentes, y más aún el de plástico, es importante tenerlos en cuenta como causa de pancreatitis aguda. Definitivamente, el abordaje laparoscópico es el ideal en pacientes sin obstrucción intestinal o inestabilidad hemodinámica


Introduction: A bezoar is defined as an indigestible element trapped somewhere in the gastrointestinal tract, which can be ingested intentionally or accidentally. The first report of a Bezoar in the medical literature was by W. Baudamant in 1779. Case report: We present the case of a plastic bezoar, a toothbrush, as the cause of acute pancreatitis and its management by laparoscopy, and a literature review. Discussion and conclusions: Although gastric bezoars are rare conditions, and furthermore so plastic bezoars, it is important to take them into account as a rare cause of acute pancreatitis. Definitely the laparoscopic approach is ideal for patients without intestinal obstruction or hemodynamic instability

ABSTRACT

Objetivo. Estimar el riesgo de padecer cáncer colorrectal y describir las características epidemiológicas-clínicas. Metodología. Estudio descriptivo, retrospectivo, muestra no probabilística por conveniencia. Mediante revisión de registros de patología e historias clínicas se analizaron variables como: edad, sexo, procedencia, estrato socioeconómico, motivo de consulta, antecedentes personales, familiares, demora diagnóstica, primer método diagnóstico, localización, histopatología, estadio y tratamiento. Adicionalmente se calcularon las tasas de incidencia. Resultados. Tasa incidencia estimada anual: Tasa cruda (TC) hombres 5,09/100.000 habitantes; Tasa ajustada para la edad (TAE): 6,75/100.000 habitantes IC 95%: (2,64-10,85); TC mujeres 4,80/100.000 habitantes, TAE: 6,07/100.000 habitantes IC95%: (2,43-9,71). Pacientes < a 40 años (7,4%). Localización más frecuente: recto (41,4%), histopatología más frecuente: bien diferenciado (53,7%), el tipo mal diferenciado tuvo (14,8%). Los exámenes diagnósticos más frecuentemente solicitados inicialmente fueron los estudios endoscópicos seguidos de la laparotomía de urgencia. Los principales motivos de consulta fueron el dolor abdominal y el sangrado digestivo bajo. El estadio tumoral más frecuente fue Duke C. Conclusión. La mayoría de pacientes presentó estadios avanzados.


Objective. Estimating the risk to suffer colorectal cancer (CRC) and describing the epidemiological and clinical features. Materials and methods: descriptive and retrospective study, with no random sample selected by convenience. Through revision of pathology’s registers and clinical histories, it analyze variables like diagnosis’s age, sex, city of permanence, stratum, principal complaints, diagnostic delay , first diagnosis exam, kind of treatment, anatomic localization, histology type, stage, personals and family antecedents. The incidence rate was calculated too. Results. The annual estimated incidence rate for the period 2000-2006, Crude rate (CR): men: 5,09/100.000 habitants, AAR: 6,75/100.000 habitants CI 95%: (2,64-10,85); CR women: 4,80/100.000 habitants, Age Adjusted Rate (AAR): 6,07/100.000 habitants CI95%: (2,43-9,71). Patients under 40 years old (7.4%). The most frequent anatomic localization was rectum, histologic type well differentiated and the first diagnosis exam the endoscopics one followed by urgency laparatomy. The main complaints were abdominal pain and low gastrointestinal bleeding, and Duke C was the stage most frequent. Conclusions. The most patients showed advanced stages of the disease.
