Renal function impairment caused by intravenous urography. A prospective study.

Renal function was evaluated before and after intravenous urography (IVU) in 124 randomly selected patients. In cases with renal insufficiency (RI) (serum creatinine level, greater than or equal to 2 mg/dL), the incidence of renal impairment was higher (11 of 20 patients, 55%) than in the group without RI (16 of 104 patients, 15%). In the latter group, high blood pressure (BP) was associated with a higher frequency of renal impairment (28.6% vs 10.5%). Advanced age, mild proteinuria, and a single functioning kidney were not risk factors. The IVU preparation contributed to renal function impairment in ten cases, while in the other 17 cases, the iodinated contrast material was the only factor apparently involved. Renal function returned to its previous level in a mean period of 12 days. One patient suffered progressive and irreversible renal failure, and two others had a slight, persistent impairment of renal function. It was concluded that the incidence of renal function impairment is high, but cases are usually mild and reversible. The most important predisposing factors are RI and high BP.

Mallory-Weiss syndrome. Evolution of diagnostic and therapeutic patterns over two decades.

During a 19-year period ending December 1978, we treated 40 patients with upper gastrointestinal bleeding secondary to the Mallory-Weiss syndrome. Thirty patients had the triad of vomiting, hematemesis and alcoholism. The presence of lacerations within the gastric cardia was associated with the presence of hiatal hernia (p = 0.03). Endoscopic examinations demonstrated 32 of 38 additional upper gastrointestinal lesions associated with the syndrome that could have been mistaken as the actual source of hemorrhage. During the second decade, as compared with the first decade, widespread use of fiberoptic esophagogastroscopy led to the identification of the bleeding lacerations in 71% of the patients (versus 47% in the first decade) and in 80% (versus 0% in the first decade) of the patients who required an operation to control the bleeding. Although there was a 7.5% mortality rate in the two decades, the incidence of operative treatment tended to decrease (42-24%; p = 0.13). More impressive were the decreases in transfusions (14 units to 5 units per patient) and in delays before surgery (38 hours to 17 hours) (p equal to 0.05). Improved endoscopic diagnosis facilitates prompt and economic treatment.

Perforated appendicitis in an incarcerated inguinal hernia.

Although perforated appendicitis in an incarcerated hernia is an uncommon condition, the clinical manifestations vary from relatively benign to much more serious, depending on whether the septic process is limited to the hernial canal and sac or if there is intraperitoneal contamination. The patient described in this report had minimal symptoms other than a slightly tender, irreducible inguinal hernia. He easily tolerated resection of the appendix and contiguous inguinal tissues, with a primary repair of the inguinal hernia.

Infrarenal mycotic pseudoaneurysm. A late complication of coronary bypass surgery with proximal aortic dissection.

A 62-year-old man developed a mycotic infrarenal pseudoaneurysm at the re-entry site of a previous aortic dissection. The aortic dissection had occurred one year earlier while he was undergoing coronary bypass surgery. The patient was successfully treated with a Dacron bifurcation graft after the mycotic aneurysm had been sterilized. Causes and relationships of the mycotic pseudoaneurysm to aortic dissection and aortic balloon support are discussed.

[Cephalic mycetoma, caused by Streptomyces somaliensis, involving the cranial cavity].

A case of cephalic mycetoma caused by Streptomyces somaliensis which has involved the orbit and craneal cavity with exoftalmus and symptoms of irritation and brain compression is reported. The patient has improved with a medical treatment (sulfomethoxazol-trimetoprim) associated with a descompressive craniectomy. The authors comment the geographic distribution of the agents of mycetoma especially of S. somaliensis very rare specie in America. Only 10 proved cases of Mycetoma caused by this Actinomycete have been found in Mexico. Our patient came from the state of Chihuahua, in the north of Mexico and is the second case from this state and the most septentrional (parallel 32 degrees) in the American continent.

[Intralobar pulmonary sequestration as the cause of neonatal respiratory distress].

A male infant 15 hours old with congenital intralobar pulmonary sequestration is described. The boy was born with tachypnea and cyanosis. A chest film revealed mediastinal displacement secondary to a cystic lesions in the lower left lobe. During surgery the lesion was found to be irrigated by an artery coming from the thoracic aorta and venous drainage was into the inferior vena cava. The lesion was spongiform and microscopic examination revealed alveolar parenchyma with irregular, dilated bronchiolar structures. Intralobar sequestrations have seldom been described in infants. Our case suggests that this malformation is congenital. We discuss the diagnostic possibilities of pulmonary cystic lesions that cause respiratory distress in neonates.
