Non-Fibrosing Exogenous Lipoid Pneumonia: presentation of a case / Neumonía lipoidea exógena no fibrosante: a propósito de un caso

ABSTRACT Exogenous lipoid pneumonia (ELP) is an unusual disease, with an incidence of 1 to 2.5%, caused by aspiration and accumulation of exogenous lipids in the pulmonary alveoli. When the aspirated agent has an oily composition, a pulmonary inflammatory reaction called lipoid pneumonia is triggered, which over time can lead to irreversible parenchymal fibrosis. Sometimes it can appear as nodular lesions that require a broad differential diagnosis, in which case imaging studies have a fundamental role. Histopathological confirmation is required for definitive diagnosis1. We present a clinical case of lipoid pneumonia which appeared as a lung mass accompanied by bilateral pulmonary infiltrates.

RESUMEN La neumonía lipoidea exógena (NLE) es una patología inusual, que tiene una incidencia del 1% al 2,5%, y tiene su causa en la aspiración y la acumulación de lípidos de origen exógeno dentro de los alvéolos pulmonares. Cuando el agente aspirado es de composición oleosa, se desencadena una reacción inflamatoria pulmonar denominada neumonía lipoidea, que con el tiempo puede conducir a una fibrosis parenquimatosa irreversible. En ocasiones, se puede presentar en forma de lesiones nodulares, que obligan a un amplio diagnóstico diferencial, en el que desempeñan un papel fundamental los estudios por imágenes. Para el diagnóstico definitivo, se requiere confirmación histopatológica1. Presentamos un caso clínico de neumonía lipoidea que se presentó como masa pulmonar acompañada de infiltrados pulmonares bilaterales.

Neumonía adquirida en la comunidad en pacientes que requirieron hospitalización / Community acquired pneumonia in patients requiring hospitalization

Resumen La neumonía adquirida en la comunidad (NAC) representa un importante problema sanitario y ~20% de los pacientes requiere hospitalización. El objetivo principal del trabajo fue determinar las características clínico-imagenológicas de los episodios de NAC que requirieron internación. Los objetivos secundarios fueron determinar el rédito diagnóstico de los estudios microbiológicos e identificar las complicaciones. Realizamos un estudio analítico retrospectivo en un hospital de tercer nivel durante el período 2017-2019, en adultos admitidos por NAC, excluyendo embarazadas. Identificamos 340 episodios en 321 pacientes, la mediana de edad fue 75 años (rango intercuartil 57-85). Los factores de riesgo más frecuentes fueron inmunocompromiso (30%), enfermedad neurológica (22%) y enfermedad renal crónica (17%). Según tres scores pronósticos de gravedad, CURB65, qSOFA y PSI/PORT, 216 (63.5%), 290 (85.3%) y 130 (38%) episodios fueron identificados como de bajo riesgo, respectivamente. Del total de los episodios, 49 (14.4%) requirieron internación en unidad de cuidados intensivos, 39 (11.5%) ventilación mecánica y se registraron 30 (8.8%) muertes durante la hospitalización. Los patrones de imagen más frecuentes fueron consolidativo en 134 (39.4%), intersticio-alveolar en 98 (28.8%) y mixto entre ambos patrones en 67 (19.7%) episodios. Identificamos el agente causal en 79 (23.2%) episodios. Los microorganismos aislados más frecuentemente fueron influenza en 37 (10.9%) y Streptococcus pneumoniae en 11 (3.2%). La mayoría de los episodios afectaron pacientes ancianos y el principal patrón radiológico fue el consolidativo. El agente causal se pudo identificar en uno de cada cuatro episodios y el método con mayor rédito diagnóstico fue el test para influenza.

Abstract Community-acquired pneumonia (CAP) represents a major health issue and ~20% of the patients require in-hospital attention. The main objective of the study was to determine clinical-imaging features of CAP episodes requiring hospitalization. The secondary objectives were to determine the diagnostic yield of microbiological analyses and the medical complications. A retrospective analytical study was conducted on adults admitted due to CAP in a third-level hospital in the period 2017-2019. Pregnant women were excluded. A total of 340 CAP episodes were identified in 321 patients; the median age was 75 years old (interquartile range 57-85). The most frequent risk factors were immunocompromise 102 (30%), neurological disease 75 (22%), and chronic kidney disease 58 (17%). According to three prognostic scores, CURB65, qSOFA and PSI/PORT, 216 (63.5%), 290 (83.5%) and 130 (38%) patients were identified as low risk, respectively. A total of 49 (14.4%) episodes required admission at the critical care unit and 39 (11.5%) required mechanical ventilation; 30 patients (8.8%) died during hospitalization. The radiologic patterns most frequently found were consolidation in 134 (39.4%), interstitial-alveolar pattern in 98 (28.8%), and the combination of both patterns in 67 (19.7%) episodes. Identification of the causal agent was achieved in 79 (23.2%) episodes. The most frequently isolated microorganisms were influenza virus in 37 (10.9%) episodes and Streptococcus pneumoniae in 11 (3.2%). Most of the hospitalized CAP patients were elderly with consolidative radiological patterns. The causal agent could be identified in less than a quarter of the patients, with the influenza test being the method with the highest diagnostic yield.

Objective. To describe the characteristics of treated patients and assess the results obtained. Subjects and methods. All patients (n=162) who underwent this technique between June 2005 and December 2010 at the Hospital de Fuenlabrada were included. Results. The mean age was 51.64 years, mean body max index was 28.92kg/m2 and the mean number of vaginal deliveries was 2.31. Urodynamic diagnosis was performed in 96.3%, with findings of pure stress incontinence in 68.5%, mixed incontinence and stress incontinence in 25.9%. Intraoperative complications occurred in 3.1%. Mesh erosions were found in 1.2%. The overall objective cure rate was 92% and the subjective cure rate was 80.3%. Conclusions. The complications rate was low and all complications were resolved. Cure rates were highly satisfactory both in pure stress urinary incontinence and in mixed urinary incontinence with a predominance of stress incontinence. Urodynamic studies before surgery allow good surgical indications and guide postsurgical prognosis (AU)

Syringomatous adenoma of the nipple--treatment by central mound resection and oncoplastic reconstruction.

Syringomatous adenoma (SA) of the nipple is a rare tumor first described by Rosen in 1983. It is histologically similar to skin adnexal tumors in other parts of the body. It has been reported under several names including low-grade adenosquamous carcinoma, SA of the nipple, and infiltrating SA of the nipple. Clinical examination and mammographic evidence yield high suspicion for carcinoma and often these lesions are misdiagnosed. Because the lesion involves the nipple, surgical treatment has ranged from local excision to mastectomy. There are 31 cases reported in the English literature, and although they all recommend complete excision, none describe reconstructive efforts. This case report describes a case of SA of the nipple presenting as a chronic abscess. We discuss the surgical treatment including reconstruction after central mound resection as well as pathological findings.

Video-assisted thoracoscopic surgical excision of cystic lung disease in children.

PURPOSE: Video-assisted thoracoscopic surgical (VATS) technique for resection of cystic lung disease (CLD) may offer some advantages when compared with thoracotomy in children. METHODS: From September 1999 to August 2004, 6 pediatric patients underwent VATS for CLD. Patients were chosen for VATS based upon surgeon's choice. Data are expressed as mean +/- SD. The Children's Healthcare of Atlanta institutional review board approved this study. RESULTS: The types of lesions included congenital cystic adenomatoid malformations (n = 1), extrapulmonary sequestrations (n = 3), congenital lobar emphysema (n = 1), and bronchogenic cyst (n = 1). The extent of resection included lobectomy (n = 2) and excision (n = 4). Age and weight were 11.8 +/- 18 months (range 6 days to 4 years) and 7.5 +/- 3.6 (range 4.0-14.0) kg, respectively. Operating time was 103 +/- 70 (range 38-223) minutes. Chest tube duration was 1.2 +/- 0.8 (range 0-2) days. Morphine use on the first postoperative day was 0.2 +/- 0.3(range 0.05-0.20) mg/kg. Length of stay was 2.5 +/- 1.9 (range 1-6) days. There were no conversions to thoracotomy and no complications. CONCLUSION: VATS technique appears to be a safe and effective technique in managing CLD in children of all ages. More patients, however, need to be studied.
