Ulcerative and pyogranulomatous pododermatitis due to Pseudomonas luteola infection in a domestic ferret (Mustela putorius furo): a case report with literature review of this emerging zoonotic disease in ferrets.

Pseudomonas luteola (P.luteola), formerly called Chryseomonas luteola, is a strict aerobic gram-negative bacillus, 0.8 to 1.0 µm wide and 1.5 to 2.5 µm long, considered an opportunistic pathogen found ubiquitously in humid environments, both in soil and water. It sporadically causes disease in animals and immunosuppressed humans or those subjected to invasive procedures such us peritoneal dialysis or catheterization. In ferrets, this infection was first described in Spain in 2012 and since then, cases have appeared occasionally in Finland, Austria, Australia, France, the United States and also in Spain. This pathogen is considered an emerging zoonotic disease in ferrets, causing respiratory disease, panniculitis, and abscesses due to pyogranulomatous or suppurative inflammation predominantly of the pleura, lung, mediastinum, panniculus or salivary glands, frequently with lethal consequences. The clinical case of a ferret, infected by Pseudomona luteola, presenting with ulcerative suppurative pododermatitis and ipsilateral popliteal purulent lymphadenitis, is described. Together with a complete resolution of the clinical case by means of a non-invasive medical management likely due to the rapid detection, identification, and treatment of the infection.

Use of a local anaesthetic and antiseptic wound formulation for the treatment of lambs naturally infected with Orf virus.

Contagious ecthyma (CE) is a worldwide highly contagious zoonotic viral skin disease of sheep and goats. Treatment for Orf virus (ORFV) infection usually involves topical and oral antibiotics. An anaesthetic and antiseptic topical gel (Multisolfen® or Tri-Solfen®; MS®, Medical Ethics, Australia) has been documented as an efficacious therapy for lesions from mucosal and epithelial viral infections in ruminants. The present study tested a new treatment protocol of MS® for CE therapy on-farm in 150 lambs naturally infected with ORFV. Lambs were divided into three cohorts of 50 lambs each (C, D and E). Cohort C was treated with MS® 3 times with an interval of 3 days between treatments, cohort D was treated daily with hypochlorous acid, whilst cohort E served as untreated controls. The lambs were examined clinically every two days, weight measured weekly, with whole blood and sterile swabs from ORFV lesions collected for haematological analysis and specific ORFV PCR. Cohort C presented fewer lambs displaying ORFV-associated lesions than other cohorts at different times of the experiment. Further, lesions treated with MS® were milder compared with other cohorts. However, following cessation of therapy, most of the lambs again developed ORFV-associated lesions. No differences between cohorts were observed in weight, haematological and PCR results. These findings suggest that topical treatment with MS® is effective for CE in field conditions, especially in the first stages of the clinical course, although treatment with MS® may need to be extended a minimum of 4 weeks.

First Evidence of Leishmania infantum Antibodies in Sheep (Ovis aries) from Southern Germany.

In Europe, Leishmania infantum is the most prevalent Leishmania species, and this protozoan is transmitted by phlebotomine sandflies. A recent publication has shown that sheep harbor L. infantum antibodies. This raises questions about the epidemiological role of small ruminants. Therefore, sera from small ruminants located in two southern German federal states, Baden-Wuerttemberg (BW) and Bavaria (BAV), were analyzed with an ELISA to determine the presence of L. infantum antibodies. The species, sex and age (gimmer vs. ewe) were recorded, and a univariate analysis was conducted to determine possible associations. In total, seven sheep flocks (274 sheep/10 goats) from BW and seven sheep flocks (277 sheep/78 goats) from BAV were examined. In BW, four sheep from three flocks tested positive for L. infantum antibodies. In BAV, the same number of positive sheep were detected but in four flocks. The total seropositivity rate in sheep was 1.45%. All goats tested negative. No significant association (p > 0.05) was detected between Leishmania seropositivity and the variables evaluated. Our study reveals the exposure of sheep to L. infantum in a non-endemic area. Further investigation is needed to determine whether sheep can be used as sentinels to identify new phlebotomine habitats and Leishmania risk areas.

Analysing disease trajectories in a cohort of 71,849 Patients: A visual analytics and statistical approach.

BACKGROUND: Disease trajectories have become increasingly relevant within the context of an aging population and the rising prevalence of chronic illnesses. Understanding the temporal progression of diseases is crucial for enhancing patient care, preventive measures, and effective management. OBJECTIVE: The objective of this study is to propose and validate a novel methodology for trajectory impact analysis and interactive visualization of disease trajectories over a cohort of 71,849 patients. METHODS: This article introduces an innovative comprehensive approach for analysis and interactive visualization of disease trajectories. First, Risk Increase (RI) index is defined that assesses the impact of the initial disease diagnosis on the development of subsequent illnesses. Secondly, visual graphics methods are used to represent cohort trajectories, ensuring a clear and semantically rich presentation that facilitates easy data interpretation. RESULTS: The proposed approach is demonstrated over the disease trajectories of a cohort comprising 71,849 patients from Tolosaldea, Spain. The study finds several clinically relevant trajectories in this cohort, such as that after suffering a cerebral ischemic stroke, the probability of suffering dementia increases 10.77 times. The clinical relevance of the study outcomes have been assessed by an in-depth analysis conducted by expert clinicians. The identified disease trajectories are in agreement with the latest advancements in the field. CONCLUSION: The proposed approach for trajectory impact analysis and interactive visualization offers valuable graphs for the comprehensive study of disease trajectories for improved clinical decision-making. The simplicity and interpretability of our methods make them valuable approach for healthcare professionals.

Estudio retrospectivo sobre la efectividad y seguridad de la pauta antibiótica reducida a 5-7 días en la faringoamigdalitis aguda estreptocócica comparada con la pauta clásica de 10 días / Retrospective study on the effectiveness and safety of the shortened 5- to 7-day antibiotic regimen for acute streptococcal pharyngotonsillitis compared to the classic 10-day regimen

Introducción: El tratamiento antibiótico clásico de la faringoamigdalitis aguda estreptocócica es una pauta de 10 días; sin embargo, la aparición de resistencias antibióticas induce a explorar pautas más cortas. Material y métodos: Seleccionamos a aquellos pacientes diagnosticados de faringoamigdalitis aguda estreptocócica en 2 cupos de pediatría de un centro de salud entre junio de 2016 y abril de 2020. Se compararon los resultados de aquellos que recibieron tratamiento 8-10 días con el de aquellos que lo recibieron 5-7 días. Resultados: Se analizaron 350 episodios (252 pacientes). El 64% recibieron tratamiento durante 8-10 días (grupo 1) y el 36% durante 5-7 días (grupo 2). No se observaron diferencias significativas en la aparición de faringoamigdalitis aguda estreptocócica o escarlatina los 3 meses posteriores (OR 0,97; IC 95%: 0,46-2,03), con una proporción similar en ambos grupos (9,8 vs. 9,5%). Sin diferenciar el tipo de infección (faringoamigdalitis aguda estreptocócica, escarlatina u otro tipo de infección streptocócica), se observaron resultados similares (OR 0,81; IC 95%: 0,41-1,59) con el 13,4% en el grupo 1 y el 11,1% en el 2. Respecto a la aparición de reacciones adversas medicamentosas recogidas en la historia clínica, fue de 2,7% en el grupo 1 y 0,8% en el 2 (OR 0,29; IC 95%: 0,04-2,44). Conclusiones: Según nuestra experiencia, la pauta antibiótica corta (5-7 días) en faringoamigdalitis aguda estreptocócica no es menos efectiva ni más insegura que la clásica pauta de 10 días. (AU)

Introduction: Antibiotherapy regimens for management of acute streptococcal pharyngitis traditionally last 10 days, but the development of resistance to different antimicrobials has motivated the exploration of shorter courses. Material and methods: We selected patients given a diagnosis of streptococcal pharyngitis in 2 paediatric caseloads of one primary care centre between June 2016 and April 2020. We compared outcomes in patients treated with 8- to 10-day courses versus 5- to 7-day courses. Results: The analysis included 350 care episodes (252 patients). Sixty-four percent were managed with 8- to 10-day courses of antibiotherapy (group 1) and 36% with 5- to 7-day courses (group 2). There were no significant differences in the incidence of streptococcal pharyngitis or scarlet fever in the 3 months that followed (OR, 0.98; 95% CI: 0.46-2.03), with similar percentages in both groups (9.8 vs. 9.5%). Overall, without differentiating based on the type of infection (streptococcal pharyngitis, scarlet fever or other streptococcal infections), we found similar outcomes (OR, 0.81; 95% CI: 0.41-1.59): 13.4% in group 1 and 11.1% in group 2. We also found no differences in the frequency of adverse events documented in the health records (OR, 0.29; 95% CI: 0.04-2.44): 2.7% in group 1 and 0.8% in group 2. Conclusions: In our experience, a shorter antibiotic course (5-7 days) is not less effective or more unsafe for management of acute streptococcal pharyngitis than the traditional 10-day course. (AU)

Scarlet fever: A not so typical exanthematous pharyngotonsillitis (based on 171 cases) / Escarlatina: una faringoamigdalitis exantemática no tan típica (a propósito de 171 casos)

AIM: To describe the age, signs and clinical symptoms of children with scarlet fever at the present time, and to check whether they are equivalent to those with traditional streptococcal pharyngotonsillitis. Study DESIGN: An observational, retrospective study was conducted on the clinical records of 5500 children aged from 0 to 15 years attending a primary health care center. A record was made of the percentage of the cases in which signs and symptoms appear and the Centor score was calculated. Microbiological diagnosis of the disease was made using the rapid antigen-detection test or traditional culture. RESULTS: A total of 171 out of 252 scarlet fever diagnoses were microbiologically verified in 158 PATIENTS: The median age was 3.8 years (interquartile range: 2.91-4.78), with the majority (57%) under the age of 4 years. There was fever in 89% of the processes (95% CI: 84-94%), with a temperature of >38°C in 73% (95% CI: 65-80%), enlarged lymph nodes in 70% (95% CI: 58-82%), absence of cough in 73% (95% CI: 65-80%), and tonsillar exudate in only 24% (95% CI: 17-31%). The Centor score (n=105) was ≤2 points in 86% (95% CI: 79-92%). The only difference regarding age is that episodes in patients under the age of 4 years old have significantly higher fever (>38°C) than the older ones (80% versus 63%. OR 3.13; 95% CI: 1.46-6.71). CONCLUSIONS: Scarlet fever pharyngotonsillitis differs from the traditional streptococcal pharyngotonsillitis, and its evaluation using clinical prediction rules such as Centor or McIsaac is questionable. The main diagnostic key must certainly be rash, regardless of patient age

OBJETIVO: Describir la edad, signos y síntomas clínicos de niños con escarlatina en la actualidad y comprobar si corresponden a los de la clásica faringoamigdalitis estreptocócica. Diseño del estudio: Estudio observacional, retrospectivo, sobre registros clínicos (5.500 niños de 0 a 15 años pertenecientes a un centro de atención primaria). Porcentaje de casos en los que aparecen los signos y síntomas y cálculo del escore de Centor. Diagnóstico microbiológico realizado mediante test rápido de detección de antígeno o cultivo tradicional. RESULTADOS: De 252 diagnósticos de escarlatina se confirmaron microbiológicamente 171, en 158 pacientes. La mediana de la edad fue de 3,8 años (rango intercuartílico: 2,9-4,8), la mayoría (57%) menores de 4 años. Hubo fiebre en un 89% de episodios (IC 95: 84 a 94%), mayor de 38°C en el 73% (IC 95: 65 a 80%), adenopatías en un 70% (IC 95%: 58 a 82%), ausencia de tos en un 73% (IC 95: 65 a 80%), y exudado amigdalar sólo en un 24% (IC 95: 17 a 31%). El escore de Centor (n=105) fue ≤ 2 puntos en un 86% (IC 95: 79 a 92%). Los niños <4 años tienen significativamente más fiebre (> de 38°C) que los mayores (80% frente a 63%. OR 3,13; IC 95: 1,46 a 6,71). CONCLUSIÓN: La faringoamigdalitis de la escarlatina difiere de la clásica estreptocócica y ha de ser cuestionada su valoración a través de reglas de predicción como las de Centor o McIsaac. La clave diagnóstica principal continúa siendo la erupción cutánea independientemente de la edad del paciente

Prevalencia del síndrome metabólico en los ancianos hospitalizados / Prevalence of metabolic syndrome in elderly patients

Objetivos. Conocer la prevalencia del síndrome metabólico (SM) según las definiciones del National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III ) y la International Diabetes Federation (IDF) y su relación con la enfermedad cardiovascular (ECV) en los ancianos hospitalizados. Material y método. Estudio descriptivo, prospectivo realizado entre febrero y marzo del 2011. Se estudiaron 200 pacientes consecutivos hospitalizados. Se registraron las variables sociodemográficas, clínicas, bioquímicas y antecedentes personales. Resultados. La prevalencia del SM fue del 65% (NCEP-ATP III ) y 67,5% (IDF), siendo mayor en las mujeres (NCEP-ATP III = 72,8%; IDF = 73,6%), que en los varones (NCEP-ATP III = 50,7%; IDF = 56,3%). La edad media de los pacientes diagnosticados de SM según ambos criterios diagnósticos fue parecido: 84,7 años. El SM no se asoció a una mayor prevalencia de ECV. Conclusiones. El SM tiene una elevada prevalencia en los ancianos hospitalizados, siendo mayor en mujeres, tanto con los criterios NCEP-ATP III como con los de la IDF. En nuestra población el SM no se asoció a una mayor prevalencia de ECV (AU)

Objectives. To determine the prevalence of metabolic syndrome (MS) according to the definitions of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) and the International Diabetes Federation (IDF) and its relation to cardiovascular disease (CVD) in hospitalized elderly patients. Material and methods. This descriptive and prospective study (February-March 2011) included 200 consecutive patients hospitalized in a Geriatric Department. Sociodemographic, clinical and biochemical data was collected. Results. The prevalence of MS was 65% (NCEP-ATP III) and 67.5% (IDF) and was greater in women (NCEP-ATP III=72.8%, IDF=73.6%) than in men (NCEP-ATP III=50.7%; IDF=56.3%). The mean age of patients diagnosed with MS by both diagnostic criteria were similar: 84.7 years. MS was not associated with an increased prevalence of CVD. Conclusions. MS is highly prevalent in elderly hospitalized patients, being higher in women, with both diagnostic criteria (NCEP- ATP III and IDF). In our population the MS was not associated with an increased prevalence of CVD (AU)

Infiltración asintomática de la próstata por leucemia linfática crónica / Assymptomatic prostatic infiltration by chronic lymphocytic leukemia

Objetivo: Presentar un caso de infiltración leucémica de la próstata como hallazgo incidental en una prueba de imagen. Métodos: Describimos el caso de un varón de 60 años en seguimiento por una leucemia linfática crónica, al que se realiza un TAC de rutina apreciando adenopatías múltiples y un nódulo hipodenso en el lóbulo prostático izquierdo. El paciente es remitido a nuestro servicio para la realización de ecografía transrectal y biopsias prostáticas. No refiere clínica urinaria. Resultados: Al tacto rectal la próstata está mal delimitada y con aumento difuso de consistencia. La ecografía transrectal muestra una glándula mal delimitada, con parénquima heterogéneo y varias áreas hiperecoicas. El informe anatomopatológico describe la infiltración difusa de la glándula por una leucemia linfática crónica. Conclusiones: Aunque la extensión de tumores hematológicos a la próstata ha sido descrita previamente, no existe en nuestro conocimiento ningún caso publicado de hallazgo incidental en una prueba de imagen de infiltración prostática por leucemia en un paciente asintomático (AU)

Objective: Report of a case of leukemic infiltration of the prostate as an incidental CT finding. Methods: We describe a case of a 60-year-old male suffering from chronic lymphocytic leukemia. A routine-performed CT showed multiple lymphadenopathies and an hypodense area in the left prostatic lobe. The patient was sent to our department to carry out a transrectal ultrasound and prostatic biopsy. He didn’t relate any urinary symptoms. Results: By the prostate rectal examination the gland felt hard and with no well defined limits. The transrectal ultrasound showed heterogene parenchyma and several hyperechoic areas by a bad circumscribed prostate. The pathological analysis reported a diffuse infiltration of the gland by chronic lymphocytic leukemia cells. Conclusions: Although the relapse of hematological tumors to the prostate has been described previously, there is no published case to our knowledge of a leukemic prostate infiltration in an assymptomatic patient as an incidental finding by an imaging procedure (AU)

Carcinoma neuroendocrino de célula grande prostático. A propósito de un caso / Large-cell neuroendocrine carcinoma of prostate. Case report

OBJETIVO: Presentar un caso de cáncer de próstata con diferenciación neuroendocrina de célula grande, un subtipo muy infrecuente. MÉTODOS: Se describe el caso clínico de un paciente previamente diagnosticado de adenocarcinoma de próstata que debuta con hematuria como progresión de la enfermedad hacia diferenciación neuroendocrina a pesar del tratamiento hormonal. DISCUSIÓN: el cáncer de próstata es el tumor más frecuente diagnosticado en el varón. Histológicamente son diagnosticados de adenocarcinoma de próstata, que tras tratamiento hormonal durante largo tiempo desarrollan una diferenciación neuroendocrina (DNE). CONCLUSIONES: el significado pronóstico de la DNE sigue siendo controvertido. Debemos pensar en la diferenciación neuroendocrina ante un paciente en tratamiento con bloqueo hormonal, con progresión de la enfermedad, y PSA bajo (AU)

OBJECTIVE: To report a case of a neuroendocrine differentiation in a prostate cancer patient, a rare subtype. METHODS: We describe the case of a patient diagnosed with adenocarcinoma of the prostate initially, who presented hematuria due to disease progression with neuroendocrine differentiation despite androgen-deprivation therapy (ADT).DISCUSSION: Prostate cancer is the most common tumor in men. Histologically they are diagnosed as adenocarcinomas, which followed by ADT for a long time, develop neuroendocrine differentiation (NED). CONCLUSIONS: The prognostic significance of NED remains controversial. We must think in neuroendocrine differentiation in ADT-treated patient with disease progression and low PSA (AU)

Radomiosarcoma paratesticular: a propósito de un caso / Paratesticular phabdomyosarcoma: a case report

OBJETIVO: Presentar un caso de radomiosarcoma paratesticular y revisión de la literatura. MÉTODOS: Describimos el caso de un varón de 16 años remitido a nuestro servicio por masa paratesticular izquierda de crecimiento progresivo, con imagen ecográfica de tumoración paratesticular heterogénea con flujo Doppler en su interior. RESULTADOS: Se realizó orquiectomía izquierda, con diagnóstico de rabdomiosarcoma. El paciente rechazó el tratamiento quimioterápico adyuvante. Tras 13 meses libre de enfermedad, reingresó por dolor cólico izquierdo detectándose en ecografía y TC una masa retroperitoneal paraaórtica izquierda que condicionaba uréterohidronefrosis grado III, y metástasis pulmonares. A pesar de instaurarse quimioterapia de rescate, no respondió presentando rápida progresión de la masa abdominal con importante deterioro general que no permitió el abordaje quirúrgico, siendo éxitus a las pocas semanas. CONCLUSIÓN: Los sarcomas paratesticulares son tumores infrecuentes y de mal pronóstico(AU)

OBJECTIVE: To report a case of paratesticular rhadomyosarcoma and to perform a bibliographic review. METHODS: We report the case of a 16-year-old male referred to our Department because of a left paratesticular hard tumor with progressive growth. Ultrasound examination showed a paratesticular heterogeneous mass with Internal flow on Doppler. RESULTS: The patient underwent left inguinal orchiectomy, with pathological diagnosis of rhabdomyosarcoma. He refused adjuvant chemotherapy. After being disease-free for 13 months, he presented with left colic pain. Ultrasound and CT examinations showed a left paraaortic retroperitoneal mass causing grade III ureterohydronephrosis, and lung metastases. Despite rescue chemotherapy treatment, there was no response and the abdominal mass progressed. A surgical approach was not possible since patient showed a rapid clinical worsening leading to his death a few weeks later. CONCLUSIONS: Paratesticular sarcomas are very uncommon tumors with poor prognosis(AU)

Bazo supernumerario simulando un tumor renal: a propósito de un caso / Supernumerary spleen simulating a renal tumor. Case report

Objetivo: Presentar un caso de bazo ectópico simulando un tumor renal. Hacemos una revisión de la etiopatogenia, diagnóstico y del tratamiento. Método: Presentamos a una paciente de 54 años esplenectomizada que se le detecta incidentalmente mediante una ecografía una masa en polo superior del riñón izquierdo simulando un tumor renal. Resultados: Tras la realización de un TAC, y bajo la sospecha de neoplasia renal, se le practicó tumorectomía de la lesión observándose en el diagnóstico histológico posterior pieza compatible con bazo supernumerario. Conclusiones: Resaltamos la importancia de incluir las pseudomasas de origen esplénico dentro del diagnóstico diferencial de los tumores renales, suprarrenales y retroperitoneales izquierdos. Destacamos la importancia del TAC como técnica de elección y de la gammagrafía como estudio complementario. Apuntamos la actitud conservadora como la más idónea en los casos de pseudomasa de origen esplénico asintomática tumor (AU)

Objective: Report one case of ectopic spleen simulating a renal tumor. We performed a review of etiopathogenesis, diagnosis and treatment. Methods: We present the case of a 54-year-old splenectomized female patient with the incidental diagnosis on ultrasound of a left kidney upper pole mass simulating a renal tumor. Results: After the performance of CT scan, and with the suspicion of renal neoplasia, the patient underwent tumorectomy with the pathologic diagnosis of the specimen compatible with supernumerary spleen. Conclusions: We emphasize the importance of including pseudo masses of splenic origin in the differential diagnosis of left renal, adrenal and retroperitoneal tumors. We emphasize the importance of CT scan as the imaging test of choice, and gammagraphy as a complementary test. We point out conservative attitude as the most suitable in cases of asymptomatic pseudomass of splenic origin (AU)

Dolor y masa gigante en hipocondrio derecho / Right hypochondrium pain and giant mass

OBJETIVO: Describir un caso de una masa gigante en hipocondrio derecho en un paciente de 40 años. MÉTODOS: Describimos un caso de un paciente de 40 años que consultó por dolor en hipocondrio derecho y aumento del perímetro abdominal. En el estudio radiológico se apreció una masa retroperitoneal de 30 x 24 x 20 cm, dependiente del polo superior del riñón derecho. RESULTADOS: Se realizó nefrectomía radical por laparotomía media. El análisis microscópico demostró que se trataba de un carcinoma renal de células claras pT2bM0N0. CONCLUSIÓN: Existen pocos casos publicados de carcinomas renales con hemorragia intraparenquimatosa mayores de 20 cm, el mayor de ellos, de más de 10 kg, y presentan generalmente una evolución favorable(AU)

OBJECTIVE: To report a case of a right hypochondrium giant mass in a 40-year-old patient. METHODS: We report the case of a 40 year-old male referred to our Department because of right hypochondrium pain and increased abdominal perimeter. Radiological examination showed a 30 x 24 x 20 cm retroperitoneal mass, dependent on the upper pole of the right kidney. RESULTS: We performed radical nephrectomy through a mid line laparotomy. The pathological analysis described it as a clear cell renal carcinoma pT2bN0M0. CONCLUSION: There are few reported cases of renal carcinomas with intraparenchymal bleeding exceeding 20 cm, the largest one exceeding 10 kg, and they usually show a good prognosis(AU)

Tumor testicular bilateral sincrónico con focos de neoplasia intratubular de células germinales: presentación de un caso / Bilateral synchronic testicular tumor with germ cell intratubular neoplasia foci: case report

OBJETIVOS: Presentar un caso de tumor testicular bilateral sincrónico con focos de Neoplasia Intratubular de Células Germinales (NICG) en ambos testículos. METODOS: Describimos el caso de un varón de 29 años que presenta tumoración indolora de un mes de evolución en teste izquierdo. Bajo la sospecha de tumor testicular se le realiza una ecografía escrotal, una determinación de marcadores tumorales y un estudio de extensión tumoral. RESULTADOS: En la ecografía se puede ver un teste izquierdo hipotrófico con lesión sospechosa de neoplasia e, incidentalmente, un testículo derecho con una lesión hipoecoica y aumento de flujo doppler. Se le practicó una orquiectomía bilateral con el diagnóstico de anatomía patológica de seminoma clásico con focos de Neoplasia Intratubular de Células Germinales (NICG) en ambos testículos y se completó el tratamiento con 2 ciclos de quimioterapia. CONCLUSIONES: Los tumores testiculares bilaterales sincrónicos son muy infrecuentes. El tipo histológico más frecuente es el seminoma clásico. El diagnóstico y tratamiento es similar al de los tumores testiculares unilaterales excepto en determinados casos en los que se puede plantear la resección parcial del testículo (AU)

OBJECTIVE: To report one case of bilateral synchronic testicular tumor with germ cell intratubular neoplasia foci affecting both testicles. METHODS: We describe the case of a 29-year-old male presenting with a painless tumor in the left testicle for a month. With the suspect of testicular tumor scrotal ultrasound, tumor markers and extension study to rule out metastasis were performed. RESULTS: Ultrasound showed a hypertrophic left testicle with a lesion suspect for neoplasia, and incidental diagnosis of a hypoechoic lesion with augmented Doppler flow within the right testicle. Bilateral orchyectomy was performed with the pathologic diagnosis of classic seminoma with germ cell intratubular neoplasia foci in both testicles. Treatment was completed with two cycles of chemotherapy. CONCLUSIONS: Bilateral synchronic testicular tumors are very rare. The most frequent histological type is classic seminoma. The diagnosis and treatment are similar to unilateral testicular tumors except certain cases in which partial excision of the testicle may be considered

Edema del escroto agudo idiopático: presentación de dos casos / Idiopathic scrotal edema: report of two cases

OBJETIVO: Presentar dos casos de edema de escroto agudo idiopático. MÉTODOS: Describimos los casos de dos varones de 12 años que acudieron al Servicio de Urgencias de nuestro hospital presentando dolor, edema y eritema en un hemiescroto sin recordar antecedente traumático previo. RESULTADOS: A la exploración de ambos pacientes se puede observar los hemiescrotos enrojecidos y aumentados de tamaño pero con testes y epidídimos normales. Con el diagnóstico de escroto agudo se les efectuaron unas ecografías en las que se pudo ver un edema heterogéneo en piel escrotal con flujo Doppler aumentado y testes ecográficamente normales. CONCLUSIONES: El edema de escroto agudo idiopático es una patología autolimitada que afecta básicamente a niños prepúberes que debe ser incluida en el diagnostico diferencial del escroto agudo para evitar intervenciones más agresivas innecesarias

OBJECTIVE: To report two cases of acute idiopathic scrotal edema. METHODS: We describe the cases of two 12-year-old male patients presenting at the emergency department of our hospital with pain, edema and erythema in one hemiscrotum without history of trauma. RESULTS: On physical examination both patients showed red hemiscrotum skin and increase of the size with normal testicles and epididymis. With the diagnosis of acute scrotum testicular ultrasound were performed and showed heterogeneous edema of the scrotal skin with increased in Doppler flows and normal testicles. CONCLUSIONS: Acute idiopathic scrotal edema is a self-limited pathology which basically affects children before puberty and should be included in the differential diagnosis of acute scrotum to avoid aggressive interventions

Serotipos de neumococo en nasofaringe de niños preescolares sanos tras la vacunación antineumocócica conjugada heptavalente / Nasopharyngeal carriage of pneumococcal serotypes in healthy pre-school aged children after 7-valent pneumococcal vaccine

Fundamento y objetivo: Tras la introducción de la vacuna neumocócica conjugada heptavalente (VNC-7v) se plantea investigar en nuestro medio las características que influyen en la colonización por serotipos de neumococo en niños preescolares sanos, la distribución de serotipos y su sensibilidad a antimicrobianos.Sujetos y método: Entre febrero de 2008 y enero de 2009 se recogieron muestras nasofaríngeas a niños de entre 2 meses y 5 años de edad que acudían a revisiones del niño sano en 4 centros de atención primaria de la provincia de Zaragoza (España) para cultivo y serotipado. Mediante regresión logística se estudiaron diferentes variables relacionadas con el estado de portador y las resistencias.Resultados: De los 371 niños estudiados, un 30,7% portaban neumococo en la nasofaringe. Con una cobertura de VNC-7v del 66%, factores relacionados con el hecho de ser portador fueron el número de hermanos (odds ratio [OR] 1,44; intervalo de confianza del 95% [IC 95%] 1,05 a 1,97 por cada hermano), estar escolarizado o asistir a guardería (OR 3,99; IC 95% 2,00 a 7,96), y padecer afección leve de vías respiratorias altas en el momento de la toma (OR 1,72; IC 95% 1,02 a 2,90). Solamente correspondían a serotipos incluidos en la vacuna (STV) un 8,7%. Los serotipos no vacunales más frecuentemente aislados fueron 19A, 6A, 15B, 11 y 15A. Se detectaron significativamente más resistencias a antibióticos entre los STV. Conclusiones: Los niños menores de 6 años de nuestro medio portan neumococos más frecuentemente cuando tienen hermanos, están escolarizados o padecen afecciones leves de vías respiratorias altas. Tras la introducción de la vacuna VNC-7v, los STV son casi anecdóticos (8,7%) y los serotipos emergentes presentan mejor sensibilidad a antibióticos (AU)

Background and objective: To determine the characteristics influencing pneumococcal serotype colonization in healthy pre-school aged children, the distribution of serotypes and their antimicrobial susceptibility, after the introduction of pneumococcal 7-valent conjugate vaccine (VNC-7v). Sujetos and methods: Nasopharyngeal samples were collected from children under 6years of age attending well-child examinations in the province of Zaragoza (Spain). Logistic regression was used to study different variables related to the status of the carriers. Results:Of the 371 children studied 30.7% were found to be carriers. With a vaccine coverage rate of 66%, factors related with presence of pneumococcal carriage were found to be the number of siblings (OR 1.44; CI 95% 1.05-1.97 for each sibling), attending a school or child day care centre (OR 3.99; CI 95% 2.00-7.96) and suffering from a minor upper respiratory tract infection (URTI) (OR 1.72; CI 95% 1.02-2.90). Only 8.7% corresponded to VNC-7v serotypes. The most common non VNC-7v serotypes isolated were 19A, 6A, 15B, 11, and 15A. Significantly greater resistance was detected among VNC-7v serotypes. Conclusion: Children in the setting of this study carried pneumococci more commonly when they have siblings, attend school or day care, or suffer from minor URTI. In the VNC-7v vaccine era, VNC-7v serotypes have become rare occurrences (8.7%) and emerging serotypes present better susceptibility to antibiotics (AU)
