Ventriculoperitoneal shunt failure resulting from complications of the thoracic segment of the shunt catheter. Case report.

A case of intrathoracic ventriculoperitoneal (V-P) catheter placement and migration resulting in hydrothorax is presented to direct attention to complications involving the thoracic segment of V-P shunt tubing. Inadequate catheter length and upper and lower thoracic segment disconnections are also discussed in addition to the role of radiography, nuclear medicine, and computed tomography (CT) in their evaluation. The lateral thoracic roentgenogram is useful in screening post shunt patients to exclude catheter deviation. Sonography over the extrathoracic tube course offers a rapid check for adjacent fluid collections as the tubing is frequently palpable and easily located by the anterioposterior roentgenogram.

Targeting the respiratory muscles of fetal sheep for prenatal gene therapy for Duchenne muscular dystrophy.

OBJECTIVE: Duchenne muscular dystrophy (DMD) is a lethal degenerative muscular disease. Fetal gene therapy may correct the primary genetic defect. Our aim was to achieve expression of a reporter gene in the respiratory muscles of early gestation fetal sheep. STUDY DESIGN: An adenovirus vector containing the beta-galactosidase reporter gene (AdRSVbetagal) was injected into the thoracic musculature (n = 3) and pleural cavity (n = 6) of fetal sheep (61-67 days' gestation) under ultrasound guidance. Tissues were harvested after 48 hours and site and intensity of beta-galactosidase expression were assessed. RESULTS: Limited transgene expression observed after a single injection was improved by multiple injections, but remained localized. Ultrasound-guided creation of a hydrothorax led to an increase in the intensity of beta-galactosidase expression (ELISA). X-gal staining and immunohistochemistry showed that vector spread was confined to the innermost intercostal musculature. CONCLUSION: Ultrasound-guided injection can deliver gene therapy vectors to the fetal pleural cavity and achieve transduction of the respiratory muscles.

A new periparturient disease in Eastern Europe, Clostridium difficile causes postparturient sow losses.

Postparturient sow losses caused by Clostridium difficile have not been reported in the veterinary literature. Recently in Croatia, in a large outdoor production unit with suboptimal environmental conditions, a sudden increase in postparturient sow mortality was diagnosed. After postpartal application of enrofloxacine to postparturient mastitis metritis agalactia (MMA) suffering sows, diarrhea, respiratory distress, and mortality of these sows were recorded. While 13% of MMA suffering and treated sows died, only 0.4% of the non-treated (no MMA suffering) sows died postpartum. Gross pathology revealed mesocolonic edema, hydrothorax, and ascites. Microscopic examination showed scattered foci of suppuration in the colonic lamina propria and accumulation of neutrophils and fibrin on colonic mucosa. Anaerobic cultures of the colon yielded heavy growth of C. difficile. Enzyme immunoassay revealed C. difficile toxins A and B. C. difficile infections of postparturient MMA suffering sows may be associated with environmental stress, the application of antibiotics, or both. C. difficile infections are an impending danger in Eastern Europe and does not only raise animal welfare issues, but seriously inflict the economical well being of outdoor production units.

Complications of nasoenteric feeding tubes.

Small-bore, silicone nasoenteric feeding tubes are increasingly utilized in the critically ill patient to provide nutritional support. The metallic-weighted tips and stiffening introducing stylets create the potential for misplacement with potentially serious consequences. We have reported our experience with 14 patients who had inadvertent tube misplacement, resulting in complications that included pneumothorax, hydrothorax, empyema, mediastinitis, pneumonia, and esophageal perforation. The incidence of radiographically detected abnormal tube position was 1.3 percent. The presence of cuffed tracheostomy or endotracheal tubes did not prevent this occurrence. The institution of enteral feedings should, therefore, be performed according to strict guidelines which include radiographic confirmation of desired position before feedings are initiated, limited and supervised use of stylets, and a need for special precautions in patients who are obtunded or receiving intubated respiratory assistance.

Determinants of mortality in patients with advanced cirrhosis after transjugular intrahepatic portosystemic shunting.

BACKGROUND & AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) placement is effective in the treatment of complications of portal hypertension. This study evaluated the predictors of mortality in a group of cirrhotic patients with advanced liver disease after placement of TIPS. METHODS: A retrospective analysis of all patients undergoing TIPS placement over a 21/2-year period was undertaken. RESULTS: Fifty-six patients had TIPS placement for variceal hemorrhage, 49 for refractory ascites, and 24 for hepatic hydrothorax (total, 129). Of 21 variables available before TIPS placement, variceal hemorrhage requiring emergent TIPS placement (relative risk [RR], 37.5; 95% confidence interval [CI], 5.4-259) and bilirubin concentration > 3.0 mg/dL (RR, 5.4; 95% CI, 1.4-10.2) were independent predictors of 30-day mortality. Variceal hemorrhage requiring emergent TIPS placement (hazard ratio [HR], 5.1, 95% CI, 2. 2-9.1), alanine aminotransferase level > 100 IU/L (HR, 2.5; 95% CI, 1.2-5.5), bilirubin level > 3.0 mg/dL (HR, 2.6; 95% CI, 1.1-4.6), and pre-TIPS encephalopathy unrelated to bleeding (HR, 2.2; 95% CI, 1.2-4.8) independently predicted death during the follow-up period. A model was developed that separated the patients into 3 groups with significantly different survival rates. CONCLUSIONS: A clinical index consisting of 4 pre-TIPS variables can reliably predict outcome after TIPS.

Transjugular intrahepatic portosystemic shunt: current status.

The transjugular intrahepatic portosystemic shunt (TIPS) was developed in the 1980s for treatment of complications of portal hypertension. Once it was shown that the shunt could be placed with relative ease, TIPS was rapidly applied to the treatment of many of the complications of portal hypertension. These complications include actively bleeding gastroesophageal varices, prevention of rebleeding from varices, control of refractory cirrhotic ascites and hepatic hydrothorax, and treatment of hepatorenal failure and hepatopulmonary syndrome. TIPS has also been used as therapy for Budd-Chiari syndrome and veno-occlusive disease. Despite these broad applications, TIPS has been compared with other forms of therapy in only 2 situations: prevention of rebleeding from varices and control of refractory cirrhotic ascites. In the trials, TIPS was shown to provide better control of these 2 complications of portal hypertension than standard forms of therapy. However, there was no improvement in survival and the incidence of encephalopathy was greater for patients receiving a TIPS. Thus, the use of TIPS for the control of ascites and prevention of rebleeding from varices should be limited to a select group of patients. There have been no controlled trials for the other indications listed. Despite the apparent efficacy of TIPS in many of these situations, its use should be limited to salvage therapy pending the publication of controlled trials showing it is a better treatment than other forms of therapy.

Mechanical coupling and liquid exchanges in the pleural space.

The pleural space provides the mechanical coupling between lung and chest wall: two views about this coupling are reported and discussed. Information on volume, composition, thickness, and pressure of the pleural liquid under physiologic conditions in a few species is provided. The Starling pressures of the parietal pleura filtering liquid into pleural space, and those of the visceral pleura absorbing liquid from the space are considered along with the permeability of the mesothelium. Information on the lymphatic drainage through the parietal pleura and on the solute-coupled liquid absorption from the pleural space under physiologic conditions and with various kinds of hydrothorax are provided.

Meigs' syndrome: the history of the eponym.

Meigs' syndrome is defined as presence of ascites with hydrothorax in association with benign ovarian tumor. The syndrome is named after Joe Vincent Meigs (1892-1963), a Harvard Medical School Professor of Gynecology. However, it was described by several authors in the 19th and the beginning of 20th centuries. Meigs and Cass deserve the credit for awakening the medical profession to the importance of the syndrome in 1937. At the end, the syndrome was coined Meigs' syndrome by Rhodes and Terrell in 1937.

Supracostal approach in percutaneous nephrolithotomy: experience with 102 cases.

PURPOSE: To assess retrospectively the safety and efficacy of the supracostal approach in percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: Among 862 patients who underwent PCNL between April 1986 and December 1999, supracostal puncture was performed in 102. Their stones were either solitary (66.5%), multiple (15.7%), or staghorn (19.6%). Upper ureteral calculi were the commonest indication (32.4%). The interspace between the 11th and 12th ribs was used in all cases. After tract dilatation with telescopic metal dilators, pneumatic or ultrasound lithotripsy was used for fragmentation. RESULTS: Complete clearance was achieved in 79.5%. Ten patients (9.8%) had pleural violation in the form of hydrothorax, pneumothorax, or hydropneumothorax. All of these patients were managed successfully by intercostal chest tube drainage. CONCLUSION: Supracostal puncture in a safe and effective approach with acceptable morbidity in selected cases of staghorn, upper ureteral, and upper caliceal calculi.

The transjugular intrahepatic portosystemic shunt in the treatment of portal hypertension.

The transjugular intrahepatic portosystemic shunt (TIPS) represents a major advance in the treatment of complications of portal hypertension. It is most commonly used in the management of refractory variceal bleeding, where it can be life-saving. Two other indications have been studied in randomized controlled trials: prevention of variceal rebleeding and refractory cirrhotic ascites. These trials have demonstrated that TIPS is superior to standard therapy but is associated with a higher rate of hepatic encephalopathy and with no improvement in survival. Consequently, TIPS is considered a second-line therapy in these situations. TIPS has also been used successfully in the treatment of hepatic hydrothorax, hepatorenal syndrome, severe portal hypertensive gastropathy, Budd-Chiari syndrome and veno-occlusive disease. Its use in these indications has only been reported in small uncontrolled series. TIPS usefulness is limited by two major problems: shunt dysfunction and hepatic encephalopathy. Shunt dysfunction is frequently responsible for the recurrence of complications of portal hypertension, and requires a surveillance program to monitor shunt patency. The use of polytetrafluoroethylene-covered stents may help prevent this complication.

Radionuclide evaluation of pleural-peritoneal shunt before pleurodesis.

OBJECTIVES: Talc pleurodesis can be offered to patients with hepatic hydrothorax. The authors wanted to determine their patient's eligibility for talc pleurodesis by excluding a pleural-peritoneal shunt. MATERIALS AND METHODS: The authors measured the size of the talc particles and matched them with the radionuclide particle size. After injecting radiopharmaceutical into the pleura, the authors imaged the abdomen for possible migration. RESULTS: In their patient, there was no migration of radionuclide from the thorax into the abdomen. CONCLUSION: Injecting radionuclide into the thoracic cavity and then imaging for an extended period of time is one way to determine whether the patient has a pleural-peritoneal shunt.

Toxic effects of violamycin Bi, carminomycin and daunorubicin on the myocardium of rabbits.

Cardiac toxicity of the new anthracycline antitumour antibiotics violamycin BI (V) and carminomycin (C) was studied in comparison with daunorubicin (D). Rabbits were intravenously given total doses of 0.1-1.5 mg/kg V or C, and 0.64-18 mg/kg D, respectively, twice weekly for one month. When examined two to six days, two and four weeks, respectively, after the last drug administration the gross findings consisted of hydropericard, hydrothorax and ascites in some animals. Histologically, loss of striation and focal necrosis of cardiac muscle cells and subsequently chronic inflammatory reactions and/or proliferation of mesenchyma cells were mostly found. These alterations were somewhat more pronounced in rabbits treated with V than in animals received D or C. At equitoxic doses of the antibiotics tested the ultrastructural lesion in the myocardial cells were altogether less marked after treatment with D than with C or V.

Value of pleural lactate in the differential diagnosis between empyema and non-bacterial pleural effusions.

Lactate concentrations in the pleural fluid of 50 patients were determined by the Monotest Lactate Kit. Lactate values were found higher in bacterial pleural infections than in cases of hydrothorax. Elevated levels were also found in most cases of histologically confirmed cases of pleural neoplasms and in some cases of non-bacterial pleuritis exsudativa . The highest levels were found in cases of empyema, but there was considerable overlapping between the groups. Pleural lactate thus appears to have little diagnostic value in the differential diagnosis between empyema and non-bacterial pleural effusions.

The LeVeen shunt.

Ascites is the end result when the rate of conversion of plasma to peritoneal fluid exceeds the rate of reabsorption from the peritoneal cavity. Physiologic therapy demands the return of this fluid to the plasma volume from whence it arose. The peritoneovenous shunt was devised to accomplish this. If precautionary measures are followed, complications are avoided. The shunt can be accomplished with a mortality under 1% in uncomplicated cirrhosis without jaundice or hydrothorax. Postoperative coagulopathy and infection are avoidable complications. Shunt failure is partly preventable and can almost always be remedied. Patients must be carefully followed to prevent late sepsis: care must be even more rigorous than that given to implanted artificial heart valves, because of the lower resistance of cirrhotics to infection. The cause of death in ascites untreated by shunts is early renal failure that is averted by the shunt. The shunt does not prevent rupture of esophageal varices, a frequent mode of late mortality. Varices require separate therapy. Because the shunt is effective with minimal morbidity and mortality, the indications for a peritoneovenous shunt should be liberalized.

Nasopulmonary intubation with feeding tubes: case reports and review of the literature.

Pulmonary aspiration of regurgitated feeding material is a recognized complication of enteral nutrition by feeding tube. Nasopulmonary intubation with feeding tubes has been reported infrequently. We present two patients with such complications. In one, nasopulmonary intubation resulted in a pneumothorax. In the other unrecognized misplacement resulted in pneumonia and hydrothorax. Similar cases in the literature are discussed. Common features of this complication are: (1) patients who are obtunded, debilitated, or without gag reflex; (2) previous successful insertion of a tube; (3) successful passage past endotracheal tubes and tracheostomies; and (4) positive auscultation of insufflated air over the left upper quadrant. Complete prevention of this complication probably is not possible, but health care personnel should be aware of this potential problem in the patient at risk.
