Título: Histopathological analysis of the non - tumour parenchyma following radical nephrectomy: can it predict renal functional outcome?
Fonte: Int. braz. j. urol;43(4):655-660, July-Aug. 2017. tab, graf.
Idioma: en.
Resumo: ABSTRACT Introduction Radical nephrectomy (RN), a recommended treatment option for patients with Renal cell carcinoma (RCC) leads to an inevitable decline in global renal function. Pathological changes in the non-tumour parenchyma of the kidney may help predict the function of the remaining kidney. Materials and Methods Aim of this prospective, observational study was to find histopathological factors in the non-tumor renal parenchyma that could predict the decline in global renal function postoperatively and its association with co-morbidities like diabetes (DM). Data of consecutive patients undergoing RN from December-2013 to January-2015 was collected. Non-tumor parenchyma of the specimen was reported by a dedicated histopathologist. eGFR was calculated using Cockcroft-Gault formula before the surgery and at last follow up of at least 12 months. Results 73 RN specimens were analyzed. Mean follow up was 12.3 months. The mean decrease in eGFR was 22% (p=.0001). Percent decrease in eGFR did not show association with any of the histopathological parameters studied. DM was significantly associated with decrease in percent eGFR (p<0.05) and increase in arteriolar hyalinosis (p=0.004), Glomerulosclerosis (p=0.03) and Interstitial fibrosis/ Tubular atrophy (p=.0001). Maximum size of the tumor showed a negative correlation with percentage change in eGFR (p=.028). Conclusion Histological parameters in the non-tumour portion of the RN specimen may not be able to predict renal function outcome over a short follow up. However, presence of DM was associated with adverse pathological changes and significant decrease in renal function postoperatively.

Título: Open partial nephrectomy for entirely intraparenchymal tumors: a matched case-control study of oncologic outcome and complication rate
Fonte: Int. braz. j. urol;43(2):209-215, Mar.-Apr. 2017. tab.
Idioma: en.
Resumo: ABSTRACT Purpose To compare the oncologic and clinical outcomes for open partial nephrectomy (OPN) performed in patients with entirely intraparenchymal tumors versus case-matched controls, with exophytic lesions. Material and methods Patients having undergone OPN between 2007 and 2012 were investigated. Exclusion criteria included patients with a benign tumor, advanced malignancy, malignancies other than renal cell carcinoma, end-stage renal failure, or 3 or more co-existing chronic diseases. Individuals with tumors that were invisible at the renal surface were identified, and then matched with 2 controls chosen for tumor size, pathology, age, follow-up period, and presence of a solitary kidney. Oncological status, perioperative, and postoperative data were collected and compared between groups. Results 17 individuals with entirely endophytic RCC tumors and available oncologic status were identified. For five patients, only one suitable control could be identified, bringing the control group number to 29. All tumors were clear cell carcinomas staged at pT1a. Median tumor size was 25mm for endophytic lesions, and 27mm for exophytic masses (P=0.32). The operative period was extended by 20 minutes for intrarenal tumors (P=0.03), with one case of a positive surgical margin in each group (P=0.7). There were no significant differences in perioperative or postoperative complications. Median follow-up was 47 and 43 months for patients with endophytic and exophytic tumors respectively. Disease recurrence was recorded in one patient after endophytic tumor resection, and in four controls (P=0.4). Conclusions OPN shows equivalent safety and efficacy for both intrarenal RCC tumors and exophytic tumors of the same size and type.

Título: Intraparenchymal hematoma as a late complication of retrograde intrarenal surgery
Fonte: Int. braz. j. urol;43(2):367-370, Mar.-Apr. 2017. graf.
Idioma: en.
Resumo: ABSTRACT A 34 year-old woman was admitted to our hospital with left flank pain. A non-contrast enhanced computerized tomography (NCCT) revealed a 1.5x2cm left proximal ureter stone. Patient was scheduled for ureterorenoscopy (URS) and stone removal. She was submitted to retrograde intrarenal surgery (RIRS). At the postoperative 1st day, the patient began to suffer from left flank pain. A NCCT was taken, which revealed a subcapsular hematoma and perirenal fluid. The patient was managed conservatively with intravenous fluid, antibiotic and non-steroidal anti-inflammatory drug therapy and was discharged at the postoperative 6th day. Two weeks after the discharge the patient was admitted to emergency department with severe left flank pain, palpitation and malaise. KUB (kidney-ureter-bladder) radiography showed double-J stent (DJS) to be repositioned to the proximal ureter. Patient was evaluated with contrast enhanced CT which revealed an 8cm intraparenchymal hematoma/abscess in the middle part of the kidney. A percutaneous drainage catheter was inserted into the collection. The percutaneous drainage catheter and the DJS were removed at the 10th day of second hospitalization. RIRS surgery is an effective and feasible choice for renal stones with high success and acceptable complication rates. However, clinician should be alert to possible complications.

Título: Liver biopsy may facilitate pancreatic graft evaluation: positive association between liver steatosis and pancreatic graft adipose infiltration
Fonte: Clinics;73:e49, 2018. tab, graf.
Idioma: en.
Resumo: OBJECTIVES: The number of pancreatic transplants has decreased in recent years. Pancreatic grafts have been underutilized compared to other solid grafts. One cause of discard is the macroscopic appearance of the pancreas, especially the presence of fatty infiltration. The current research is aimed at understanding any graft-related association between fatty tissue infiltration of the pancreas and liver steatosis. METHODS: From August 2013 to August 2014, a prospective cross-sectional clinical study using data from 54 multiple deceased donor organs was performed. RESULTS: Micro- and macroscopic liver steatosis were significantly correlated with the donor body mass index ([BMI]; p=0.029 and p=0.006, respectively). Positive gamma associations between pancreatic and liver macroscopic and microscopic findings (0.98; confidence interval [CI]: 0.95-1 and 0.52; CI 0.04-1, respectively) were observed. Furthermore, comparisons of liver microscopy findings showed significant differences between severe versus absent (p<0.001), severe versus mild (p<0.001), and severe versus moderate classifications (p<0.001). The area under the receiver operating curve was 0.94 for the diagnosis of steatosis by BMI evaluation using a cut-off BMI of 27.5 kg/m2, which yielded 100% sensitivity, 87% specificity, and 100% negative predictive value. CONCLUSIONS: We observed a positive association of macroscopic and microscopic histopathological findings in steatotic livers with adipose infiltration of pancreatic grafts.

Resumo: Resumen Antecedentes: los síndromes renales son manifestaciones clínicas y de laboratorio que indican alteraciones funcionales y morfológicas. La biopsia renal es fundamental en el diagnóstico de enfermedades renales parenquimales y aporta información valiosa sobre la incidencia, distribución y posible control de la enfermedad. Objetivo: describir las características clínicas e histológicas de las enfermedades del parénquima renal en una muestra de biopsias renales. Métodos: se incluyeron 269 pacientes mayores de 14 años, a quienes se les realizó biopsia renal por cualquier método. Se clasificaron por indicación de biopsia y por tipo de lesión renal primaria o secundaria. Resultados: el promedio de edad fue de 57,04 (DE ± 17,17 años). La mediana de creatinina fue 1,51 mg/dl (RIC=1,22 - 2,01); y la de TFG por CKD-EPI, de 42,7 mil/minuto (RIC= 30,6 - 56,5). Las indicaciones de biopsia renal más frecuentes fueron enfermedad renal crónica sin causa clara (46,8 %), proteinuria no nefrótica (20,1 %), síndrome nefrítico (8,2 %), lesión renal aguda (7,1 %), hematuria glomerular con cambio en el patrón (7,1 %), síndrome nefrótico (6,7 %) y tasa de filtración glomerular estimada baja para la edad sin causa clara (4,1 %). Los hallazgos encontrados fueron: nefropatía por IgA (20,9 %), nefropatía hipertensiva (19 %), glomeruloesclerosis focal y segmentaria (11,6 %), nefritis tubulointersticial (9,7 %), glomerulopatía diabética (8,6 %), glomerulonefritis membranoproliferativa (3,7 %) y glomerulonefritis proliferativa extracapilar (3,4 %). Conclusiones: la nefropatía por IgA y la glomeruloesclerosis focal y segmentaria son las principales glomerulopatías primarias. La nefropatía hipertensiva y la nefritis tubulointersticial son las principales etiologías secundarias.

Abstract Background: Renal syndromes are clinical and laboratory manifestations that indicate functional and morphological alterations. Renal biopsy is essential in the diagnosis of kidney parenchymal diseases and provides valuable information in incidence, distribution and possible control of the disease. Objective: To describe the clinical and histological characteristics of renal parenchymal diseases in a sample of renal biopsies. Methods: We included 269 patients older than 14 years who underwent renal biopsy by any method. They were classified by indication of biopsy and by type of primary or secondary kidney injury. Results: The average age was 57, 04 (SD ± 17, 17 years). The median creatinine was 1, 51 mg / dL (RIC=1, 22 - 2,01) and the GFR for CKD-EPI was 42,7 mil/minute (RIC=30,6 - 56,5). The most frequent renal biopsy indications were unexplained chronic kidney disease (46,8 %), non-nephrotic proteinuria (20,1 %), nephritic syndrome (8,2 %), acute kidney injury (7,1 %), glomerular hematuria with change in the pattern (7,1 %), nephrotic syndrome (6,7 %) and unexplained low glomerular filtration for age (4,1 %). The most frequent finding were IgA nephropathy (20,9 %), hypertensive nephropathy (19 %), focal and segmental glomerulosclerosis (11,6 %), tubulointerstitial nephritis (9,7 %), diabetic glomerulopathy (8,6 %), membranoproliferative glomerulonephritis (3,7 %), extracapillary proliferative glomerulonephritis (3,4 %). Conclusions: IgA nephropathy and focal segmental glomerulosclerosis are the main primary glomerulopathies. Hypertensive nephropathy and tubulointerstitial nephritis are the main secondary etiologies.

Título: Quilotorax bilateral en edad pediátrica / Bilateral chylothorax in pediatric age
Fonte: VozAndes;17(1):93-96, 2006.
Idioma: es.
Resumo: La pleura es un revestimiento para el parénquima pulmonar, mediastino, diafragma y el interior de la cavidad torácica. Existe dos tipos: la visceral y la parietal, formando una cavidad virtual con una mínima cantidad de líquido, que se torna en cavidad real si aumenta la producción de éste o si es ocupada por aire, quilo y / o sangre. Quilotórax es un derrame pleural linfático, tipo exudado que se diagnostica por análisis citoquimico del líquido pleural y causa dificultas respiratoria grave en el RN. La lesión del conducto torácico durante la cirugía cardiotorácica y la trombosis en el sistema de la vena cava superior son las causa más frecuentes de quilotórax secundario. El quilotórax idiopático es aquel en donde la causa no quede determinada luego de diferentes estudios. El tratamiento del quilotórax puede ser conservador, drenaje con evolución favorable y la cirugía se reserva para los casos de quilotórax resistente al tratamiento convencional.

The pleura is a lining for the lung parenchyma, mediastinum, diaphragm, and the interior of the thoracic cavity. There are two types: the visceral and the parietal, forming a virtual cavity with a minimum amount of liquid, which becomes a real cavity if its production increases or if it is occupied by air, chyle and / or blood. Chylothorax is an exudate-like lymphatic pleural effusion that is diagnosed by cytochemical analysis of the pleural fluid and causes severe respiratory distress in the newborn. Thoracic duct injury during cardiothoracic surgery and thrombosis in the superior vena cava system are the most common causes of secondary chylothorax. Idiopathic chylothorax is one where the cause is not determined after different studies. Chylothorax treatment can be conservative, drainage with a favorable evolution, and surgery is reserved for cases of chylothorax resistant to conventional treatment.

Resumo: Glicocorticoides são amplamente utilizados na clínica de pequenos animais, entretanto seu uso contínuo pode causar efeitos colaterais. Os gatos são considerados menos susceptíveis a esses efeitos do que outras espécies, mas existem poucos trabalhos abordando os efeitos adversos em felinos. O objetivo deste estudo foi avaliar possíveis alterações laboratoriais, histopatológicas e do grau de atenuação radiográfica do parênquima hepático de gatas submetidas à terapia com prednisolona. Um ensaio clínico foi realizado em quatro gatas hígidas, as quais receberam prednisolona, por via oral, na dose de 3mg/kg, durante 60 dias consecutivos. Nos achados histopatológicos após 60 dias de tratamento, observou-se desorganização dos cordões de hepatócitos e degeneração vacuolar, além de necrose de hepatócitos, porém não foram observados sinais de fibrose no parênquima hepático. Os dados da tomografia computadorizada demonstram aumento do grau de atenuação do parênquima hepático a partir do 30º dia da administração de prednisolona, que persistiu até o final do experimento. No presente estudo, foi possível caracterizar a existência de hepatopatia esteroidal em gatos em estágios precoces da terapia com prednisolona.(AU)

Glucocorticoids are widely used medications in small animal practice; however, its continuous use can have side effects. Cats are considered less susceptible than other species, however, the literature does not usually address adverse effects in felines. The objective of this study was to evaluate possible laboratory and histopathologic changes, as well as changes to the degree of radiographic attenuation of the hepatic parenchyma in cats treated with prednisolone. A clinical trial was done in four healthy cats, who received prednisolone orally at 3mg/kg during 60 consecutive days. In the histopathologic findings at 60 days of treatment, there were disorganized hepatocyte chords and vacuolar degeneration, as well as hepatocyte necrosis, however, there were no signs of fibrosis in the hepatic parenchyma. Data obtained via computed tomography showed increase of the degree of attenuation in the hepatic parenchyma from day 30 of prednisolone therapy, which persisted until the end of the experiment. In the present study, it was possible to characterize the existence of steroidal hepathopathy in cats in the early stages of prednisolone therapy.(AU)

Resumo: Con el objetivo de identificar hallazgos ecográficos en el parénquima tiroideo en el personal ocupacionalmente expuesto y no expuesto a radiación ionizante (RI) del Hospital Central Universitario Dr. Antonio María Pineda, se realizó un estudio descriptivo transversal con una muestra de 45 individuos expuestos a RI del Servicio de Radiología y Diagnóstico por Imágenes Dr. Theoscar Sanoja Hernández y 38 individuos de los Servicios de Traumatología y Ortopedia y Medicina Física y Rehabilitación que no están expuestos a RI obteniendo que el 63% del personal expuesto presentaron algún tipo de alteración en el ultrasonido tiroideo en comparación con el 43% del personal no ocupacionalmente expuesto; los hallazgos más frecuentes en el personal expuesto fueron bocio difuso (44%), nódulos (32%) y quistes (24%) mientras que en el personal no expuesto fueron quistes (38%), bocio difuso (19%) y nódulos (19%). Estos hallazgos permiten concluir que el porcentaje del personal con afectación de la glándula tiroides fue mayor en personal expuesto y que los hallazgos ecográficos difieren entre los grupos estudiados(AU)

In order to identify ultrasound findings in thyroid parenchyma of hospital staff exposed and not exposed to ionizing radiation (IR) of the Hospital Central Universitario Dr. Antonio Maria Pineda, we performed a cross-sectional descriptive study with a sample of 45 individuals exposed to IR who worked in the Servicio de Radiología y Diagnóstico por Imágenes Dr. Theoscar Sanoja Hernández and 38 individuals who worked at the Servicios de Traumatología y Ortopedia y Medicina Física y Rehabilitación and were not exposed. The results showed that 63% of the exposed group had ultrasound thyroid findings in contrast to 43% of the non-exposed group. The most common findings in the exposed group were diffuse goiter (44%), nodules (32%) and cysts (24%) and in the non-exposed group were cysts (38%), diffuse goiter (19%) y nodules (19%). These findings show that ultrasound thyroid findings was higher in exposed hospital staff and that the type of thyroid disease differ among both groups(AU)

Resumo: ABSTRACT Objective: Nonalcoholic fatty liver disease is the commonest diffuse liver disease, of which women with polycystic ovary syndrome are at an increased risk. The aim of the present study was to assess the diagnostic value of the semiquantitative strain parameters of real-time ultrasound elastography for nonalcoholic fatty liver disease in patients with polycystic ovary syndrome. Subjects and methods: Thirty-five polycystic ovary syndrome patients with nonalcoholic fatty liver disease, 70 polycystic ovary syndrome patients without nonalcoholic fatty liver disease, and 70 healthy female controls of reproductive age were included. All participants underwent ultrasonic examination and semiquantitative analysis of real-time ultrasound elastography of the liver. Results: Main semi quantitative strain parameters, such as average strain value, differed significantly among groups polycystic ovary syndrome with nonalcoholic fatty liver disease, polycystic ovary syndrome without nonalcoholic fatty liver disease, and control (87.02 ± 10.16 vs. 96.31 ± 11.44 vs. 104.49 ± 7.28, p < 0.001). Clinical and laboratory parameters differed significantly between the two subgroups with low or high average strain value. For diagnostic value of average strain value for elevated aminotransferase, the area under the curve was 0.808 (range 0.721-0.895). In multiple linear regression analysis, polycystic ovary syndrome, waist circumference, and metabolic syndrome were stand-alone independent factors associated with average strain value among subjects without nonalcoholic fatty liver disease. Conclusion: Semiquantitative real-time ultrasound elastography analysis could distinguish liver parenchyma alterations in patients with polycystic ovary syndrome more sensitively. The diagnostic value of the proposed method for nonalcoholic fatty liver disease need further research.
