An interesting presentation of invasive bladder carcinoma as pseudo renal failure / Uma apresentação interessante do carcinoma invasivo de bexiga como pseudo insuficiência renal

Abstract Ascites and oliguria with an increasing serum creatinine level are often observed in patients with acute renal failure. However, these symptoms are also noted in individuals with intraperitoneal urinary leakage and can be mistaken for acute renal failure. This rise in creatinine in such patients is called pseudo renal failure and it happens by a process of reverse peritoneal dialysis. In literature, the most commonly described condition that leads to this clinical picture is following a spontaneous or missed bladder perforation. We, herein, report a case of carcinoma of the bladder that presented with features resembling acute renal failure, which later turned out to be pseudo renal failure due to intraperitoneal urinary extravasation from a forniceal rupture. The patient was managed with emergency with a percutaneous drain followed by a percutaneous nephrostomy, which led to normalization of creatinine. Cystoscopy revealed the bladder growth in an intact small capacity bladder and biopsy confirmed it as a muscle invasive squamous cell carcinoma. Due to advanced nature of his malignancy, he underwent a palliative ileal conduit diversion but he later developed chest metastasis and ultimately succumbed to the disease. Intraperitoneal urinary leakage due to forniceal rupture presenting as pseudo renal failure is a rare presentation of carcinoma bladder. Sudden onset abdominal discomfort, increasing ascites, hematuria, and oliguria with elevated renal parameters needs consideration and exclusion of this entity. The diagnostic dilemma associated with this rare presentation along with the management and prognosis in such patients of carcinoma bladder are discussed.

Resumo Ascite e oligúria com um nível crescente de creatinina sérica são frequentemente observadas em pacientes com insuficiência renal aguda. Entretanto, esses sintomas também são notados em indivíduos com extravasamento urinário intraperitoneal e podem ser diagnosticados como lesão renal aguda erroneamente. Este aumento de creatinina em tais pacientes é chamado de pseudo insuficiência renal e ocorre por um processo de diálise peritoneal reversa. Na literatura, a condição mais comumente descrita que leva a este quadro clínico se dá após uma perfuração vesical espontânea ou perdida. Relatamos aqui um caso de carcinoma de bexiga que apresentou características semelhantes à insuficiência renal aguda, e mais tarde se revelou uma pseudo insuficiência renal devido a extravasamento urinário intraperitoneal de uma ruptura de fórnice renal. O paciente foi tratado com emergência com um dreno percutâneo seguido por uma nefrostomia percutânea, que levou à normalização da creatinina. A cistoscopia revelou o crescimento da bexiga em uma bexiga intacta, de pequena capacidade e que a biópsia confirmou como um carcinoma escamoso invasivo muscular. Devido à natureza avançada de sua malignidade, ele foi submetido a um desvio de conduto ileal paliativo, mas posteriormente desenvolveu metástase torácica e acabou sucumbindo à doença. O vazamento urinário intraperitoneal devido à ruptura do fórnice renal que se apresenta como pseudo insuficiência renal é uma apresentação rara do carcinoma vesical. Desconforto abdominal de início súbito, ascite crescente, hematúria e oligúria com elevados parâmetros renais precisam de consideração e exclusão desta entidade. O dilema diagnóstico associado a esta rara apresentação, juntamente com o controle e prognóstico em tais pacientes de carcinoma vesicular, são discutidos.

Transposition of Great Arteries with Intramural Coronary Artery: Experience with a Modified Surgical Technique.

OBJECTIVE: Transposition of the great arteries is a common congenital heart disease. Arterial switch is the gold standard operation for this complex heart disease. Arterial switch operation in the presence of intramural coronary artery is surgically the most demanding even for the most experienced hands. We are presenting our experience with a modified technique for intramural coronary arteries in arterial switch operation. METHODS: This prospective study involves 450 patients undergoing arterial switch operation at our institute from April 2006 to December 2013 (7.6 years). Eighteen patients underwent arterial switch operation with intramural coronary artery. The coronary patterns and technique used are detailed in the text. RESULTS: The overall mortality found in the subgroup of 18 patients having intramural coronary artery was 16% (n=3). Our first patient had an accidental injury to the left coronary artery and died in the operating room. A seven-day old newborn died from intractable ventricular arrhythmia fifteen hours after surgery. Another patient who had multiple ventricular septal defects with type B arch interruption died from residual apical ventricular septal defect and sepsis on the eleventh postoperative day. The remainder of the patients are doing well, showing a median follow-up duration of 1235.34±815.26 days (range 369 - 2730). CONCLUSION: Transposition of the great arteries with intramural coronary artery is demanding in a subset of patients undergoing arterial switch operation. We believe our technique of coronary button dissection in the presence of intramural coronary arteries using coronary shunt is simple and can be a good addition to the surgeons' armamentarium.

Is it smart to believe in God? The relationship of religiosity with education and intelligence / É inteligente acreditar em Deus? A relação da religiosidade com educação e inteligência

The relationship of religiosity with education and intelligence was investigated with data from the World Values Survey covering a total of 345,743 respondents in 96 countries. The individual-level relationship of education with religious belief was slightly but significantly negative in the majority of countries, although its relationship with religious attendance was substantially less negative. At the country level, religious belief has independent negative relationships with intelligence and a history of communist rule, but not with educational exposure and log-transformed GDP. The results suggest that a weak negative relationship of religiosity with education is culturally amplified into far larger differences at the country level, and that the effect of education is mediated by cognitive skills. The results suggest that secularization during the 20th century has been driven by cognitive rather than economic development.(AU)

A relação da religiosidade com educação e inteligência foi investigada de acordo com dados do World Values Survey abrangendo um total de 345.743 entrevistados em 96 países. No nível individual, a relação da educação com a crença religiosa foi discretamente, porém significativamente negativa na maioria dos países, apesar de que a relação com a presença religiosa foi substancialmente menos negativa. No nível nacional, a crença religiosa tem relações negativas independentes com inteligência e com um histórico de regime comunista, mas não com a exposição educacional ou com o produto interno bruto (PIB) obtido por transformação logarítmica. Os resultados sugerem que uma fraca relação negativa de religiosidade com educação é culturalmente amplificada para diferenças muito maiores no nível nacional, e que o efeito da educação é mediado por habilidades cognitivas. Os resultados sugerem que a secularização durante o século XX tem sido impulsionada pelo desenvolvimento cognitivo e não pelo desenvolvimento econômico.(AU)
