Conservative management of chylous ascites complicating aortic surgery: a case report.

Chylous ascites is an uncommon complication of aortic surgery. In the past, operative management was the standard therapy. A 62-year-old man with chylous ascites was treated successfully with paracentesis and total parenteral nutrition alone. A review of the recent literature suggests that a preliminary course of conservative therapy can limit the need for operative intervention to those who fail the primary conservative treatment.

[Current ascites therapy].

Ultrasonography detects ascites easily even in trace amounts. 80% of the cases are caused by hepatic disease, in the remaining 20% cancer, inflammation, pancreatic, renal, or cardiac disease can be found. The underlying disease should be investigated by few inexpensive laboratory test from serum, urine and ascites and by abdominal sonography. Hepatic ascites is caused by portal hypertension and disturbances of humoral factors. Sodium retention, peripheral, vasodilation, hyperdynamic circulation and progressive renal vasoconstriction lead to a stepwise deterioration of patients condition. Treatment with diuretics (furosemide, torsemide, or xipamide and spironolactone) and sodium-restriction (< 60 mval per day) control 85-90% of the cases with hepatic ascites. If this regimen fails, non-compliance, spontaneous bacterial peritonitis, hyponatremia or additional complications such as renal failure, Budd-Chiari syndrome or tumor should be considered. Ten to 15% of the patients develop refractory ascites and finally hepatorenal syndrome and have a poor prognosis. Early liver transplantation should be considered. Large volume paracentesis with albumin substitution is a therapeutic option in these patients. The transjugular intrahepatic portosystemic stent-shunt (TIPS) may be superior for patients with concurrent esophageal varices or hepatorenal syndrome. If TIPS is considered the patient should be referred to an experienced center. The peritoneo-venous shunt is restricted to rare indications. In the future, new drugs such as antagonists of endothelins or of the antidiuretic hormone may offer new therapeutic options.

Cardiac tamponade--a rare complication in acute pancreatitis.

A patient with recurrent acute pancreatitis developed pericardial effusion and cardiac tamponade. His systolic blood pressure fell to 70 mmHg and sinus tachycardia (150/min) developed. The central venous pressure rose from 3 cm H2O to 27 cm H2O. A chest radiograph showed an enlargement of the cardiac shadow. Pericardial paracentesis was performed and 300 ml fluid was aspirated. This produced rapid clinical improvement. The literature related to this uncommon complication is reviewed and possible pathogenetic mechanisms are discussed.

Management of ascites in the patient with portal hypertension with emphasis on spontaneous bacterial peritonitis.

The reintroduction of paracentesis has modified the way in which patients with ascites are treated. Transjugular intrahepatic portosystemic shunt can be an alternative treatment for patients with refractory ascites and for those patients with hepatorenal syndrome, although more studies are needed to clarify its usefulness and safety. The use of more potent and less nephrotoxic antibiotics together with an earlier diagnosis have improved the outcome of patients with spontaneous bacterial peritonitis (SBP). Oral antibiotics can be used in patients with SBP and good clinical conditions with an efficacy similar to that obtained with intravenous antibiotics. Prophylactic antibiotics in SBP should be restricted to cirrhotic patients at high risk, including bleeding cirrhotic patients, those with a past history of SBP, and those with low protein content in ascitic fluid. This chapter describes the management of ascites in patients with portal hypertension.

[Multiple organ failure syndrome after ovarian hyperstimulation].

Ovarian stimulation is used to treat female infertility, especially in Black Africa where infertility is considered as shameful. Ovarian stimulation can lead not only to multiple pregnancies but also to severe systemic complications such as the one described in this report. Ovarian stimulation using human menopausal gonadotropin led to ovarian hyperstimulation and multiple organ failure in a 28-year-old Senegalese woman. Symptomatic treatment using corticosteroids, abdominal paracentesis to relieve ascites, and fluid expansion failed. Bilateral ovariectomy was performed resulting in permanent sterility. Ovarian stimulation requires close monitoring by ultrasound visualization and measurement of 17 beta-estradiol to allow early detection of complications.

Chylous ascites following heart transplantation.

We report a case of chylous ascites in a 52-year-old woman after an orthotopic heart transplantation. The patient was successfully managed with conservative treatment including dietetic measures and repeated paracentesis. The potential aetiopathological factors involved and other implications for cardiac transplant patients are discussed.

[Integral treatment of severe ovarian hyperstimulation syndrome by means of autotransfusion of ascitic fluid and intravenous infusion of albumin].

Severe ovarian hyperstimulation syndrome (OHSS) is a potential life-threatening condition relationated with ovulation induction. It affects multiple systems. Little is known about it's pathophysiology. The treatment available consists in the correction of fluid, electrolyte and hematologic imbalances. In other hand, is mandatory the prevention of embolic phenomena. Ascitic fluid aspiration result in dramatic improvement of symptoms. The purpose of this study was to assess the effect of autotransfusion of ascitic fluid obtained by paracentesis and the intravenous infusion of albumin for the treatment of severe from of the OHSS.

The iris cerclage suture for permanent mydriasis: a running suture technique.

Permanent mydriasis can be a disabling condition. The author describes an iris cerclage running suture technique for the treatment of permanent mydriasis caused by diffuse iris sphincter damage. A long, curved transchamber needle on 10-0 polypropylene is passed in and out of the anterior chamber through limbal paracentesis openings while weaving the needle through the iris near the pupillary margin to form the cerclage. The technique minimizes stretching and distortion of the iris and creates a pupil that is precisely sized and rather round.

The therapeutic use of albumin.

In this review, we condense and summarize the results of studies on the therapeutic use of human albumin to promote the more efficient use of this costly resource. Reports of major controlled and uncontrolled therapeutic trials, reviews, and summary articles published in English between 1972 and 1991 were identified through library and MEDLINE searches. Case series, prospective studies, and blinded therapeutic trials were identified from the bibliographies of these sources. All sources were critically evaluated for information about the comparative physiologic results and patient outcomes of the therapeutic use of albumin solutions, crystalloid solutions, and volume expanders other than albumin. The therapeutic use of albumin is of marginal benefit for many conditions for which it has been administered, apparently because of the body's capacity to quickly compensate for rapid colloid osmotic shifts. Human studies show little or no demonstrable value for albumin when it is administered for nutritional supplementation, wound healing, perioperative fluid replacement, treatment of early thermal injury, or therapy during extensive retroperitoneal surgery (including aortic aneurysm resection). Therapeutic albumin has well-defined value in several special circumstances: large-volume paracentesis in cirrhotic patients, acute nephrotic syndromes with diuretic resistance, organ transplantation, and plasmapheresis. Additional studies are needed to compare the efficacy of albumin with other volume expanders. For most purposes, balanced crystalloid solutions are satisfactory substitutes for colloid volume expanders and can be obtained at a fraction of the cost of colloid volume expanders.

A paradigm for consensus. The University Hospital Consortium guidelines for the use of albumin, nonprotein colloid, and crystalloid solutions.

OBJECTIVE: To develop contemporary, comprehensive guidelines for the appropriate and efficient use of albumin, nonprotein colloid, and crystalloid solutions. DESIGN: A systematic, literature-based, consensus exercise employing a modified Delphi method. PARTICIPANTS: Thirty-one medical and allied health professionals from 26 University Hospital Consortium (Oak Brook, Ill) member institutions were initially chosen to participate. Participants were selected on the basis of their recognized research in the use of albumin, nonprotein colloid, and crystalloid solutions, and/or experience in the review of appropriateness of such use. A total of 24 participants completed the exercise. MAIN OUTCOME MEASURES: Group responses were statistically analyzed in an iterative consensus development process. Five separate questionnaire rounds were designed to establish criteria for the appropriate use of albumin, nonprotein colloid, and crystalloid solutions. RESULTS: Consensus guidelines were developed outlining the appropriate use of these products for 12 clinical indications, including hemorrhagic shock, nonhemorrhagic (maldistributive) shock, hepatic resection, thermal injury, cerebral ischemia, nutritional intervention, cardiac surgery, hyperbilirubinemia of the newborn, cirrhosis and paracentesis, nephrotic syndrome, organ transplantation, and plasmapheresis. CONCLUSIONS: The Delphi method, a systematic, literature-based consensus process, was shown to be useful in the development of complex clinical practice guidelines for the use of albumin, nonprotein colloid, and crystalloid solutions. It is anticipated that the guidelines will assist health care providers to develop local institutional policies and procedures for the appropriate and efficient use of albumin and albumin alternatives. Institutions reviewing and updating existing local guidelines may use the University Hospital Consortium guidelines as a model for comparison.

A new technique for repairing descemet membrane detachments using intracameral gas injection.

Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even corneal transplantation for persistent cases. During the past few years, intracameral injection with either sulfur hexafluoride (SF6) or perfluoropropane (C3F8) gas has gained increasing acceptance as an efficient and effective treatment option for Descemet membrane detachments. Previously described techniques of gas injection have required corneal and paracentesis incisions; sterile blades, cannulas, and other instruments; and occasionally, an operating room setting. We describe a simple, safe, and effective technique for intracameral gas injection that can be performed by one person at the slitlamp microscope or in a minor operating room with minimal equipment.

Lysophosphatidyl choline and cataracts in uveitis.

In aqueous humor from rabbits with uveitis or after anterior chamber paracentesis, the levels of lysophosphatidyl choline (LPC) were 10.2mug/ml and 14.7mug/ml, respectively. These LPC levels induce early cataractous changes in the rabbit lens in culture. Analysis of the fatty acid composition of LPC showed that saturated fatty acids were more predominant in secondary aqueous humor than in primary aqueous humor. In vitro, natural LPC induced more pronounced gains in sodium ions and water by the lens than similar concentrations of synthetic L-alpha-lysopalmitoyl phosphatidyl choline. In contrast to prostaglandin E, the levels of LPC in aqueous humor of rabbits with uveitis are cataractogenic. Thus, LPC or its precursors, rather than prostaglandins, are involved in the production of cataracts in uveitis.

Listeria endophthalmitis.

Listeria endophthalmitis developed in a patient who was being treated for extensive metastases of carcinoma of the breast. At the time of admission she was receiving cobalt therapy, chemotherapy, and high doses of oral steroids. The early identification of organisms with an immediate paracentesis and the early institution of broad-spectrum antibiotics is recommended.

Air and the corneal endothelium: an in vivo specular microscopy study in cats.

In 25 cat eyes 0.7 mL of air and in 11 cat eyes 0.7 mL of balanced salt solution were injected into the anterior chamber after paracentesis. This air persisted for three to four days, and specular microscopy was performed before and two months after air injection. There was an overall significant decrease in the endothelial cell density as a percentage of the preinjection density for the eyes with air when compared with those with balanced salt solution (102% +/- 7% for balanced salt solution and 93% +/- 11% for air). Thus, while air is generally well tolerated by the corneal endothelium, it is a toxic material in the anterior chamber and probably can cause endothelial damage. If not otherwise indicated and if safe to do so, it seems best to avoid its use or to replace it with physiologic solutions after its use.

Presumed juvenile xanthogranuloma of the iris and ciliary body in an adult.

Juvenile xanthogranuloma (JXG) of the iris is extremely rare in adults. A case of presumed JXG occurred in a 26-year-old woman who was seen initially with bilateral iris lesions and spontaneous hyphema in one eye. Diagnosis was based on the clinical picture and the finding of typical histiocytes obtained by paracentesis and examined by a polymer filtration (Millipore) cytopathologic techniques. Treatment with steroids (given orally and topically to the eye) resulted in a substantial decrease in the size of the iris lesion of the left eye. She has received no medications for 18 months and has shown no signs of progression or other complications 24 months after the initial diagnosis.

Centrifugal cytology of ocular fluids.

Centrifugal cytology is a new technique for the preparation of ocular fluids for cytologic examination. It differs from conventional cytocentrifuge techniques, since fixation is carried out simultaneously with centrifugation. It avoids air-drying artifacts and can be applied to small (50 microL) or large (200 mL or more) sample volumes and dilute cell suspensions, such as might be obtained by anterior chamber paracentesis, vitreous aspiration, or vitrectomy. The resultant preparation is a permanent, stained, well-preserved, flattened, homogeneous cell dispersion suitable for detailed cytologic evaluation.

Lipopolysaccharide tolerance inhibits eye inflammation. II. Preliminary studies on the mechanism.

The effect of endotoxin tolerance on ocular inflammation was studied in rabbits. Compared with a control group, a passive Arthus reaction in tolerant rabbits was characterized by a sharp decline in the expected increase in vascular permeability and slightly reduced leukocyte extravasation. Aqueous humor withdrawal (paracentesis) and intravitreal injection of prostaglandin E2 were also examined in lipopolysaccharide (LPS)-tolerant rabbits; in both circumstances, ocular protein exudation was decreased. These studies suggest that the prostaglandin system is particularly affected in the ocular responses of LPS-tolerant rabbits, and raise the possibility that other phenomena described in LPS tolerance may have a similar basis.

Intraocular fibrinolysis with recombinant human tissue plasminogen activator. Experimental treatment in a rabbit model.

Intraocular fibrin formation following ocular surgery is a potentially binding problem. Current therapy for this postoperative fibrin response is often ineffective. In the rabbit, we developed a quantitative reproducible model for intraocular fibrin deposition. Using this model, we have tested the efficacy of human tissue plasminogen activator (tPA) in promoting intraocular fibrinolysis. Citrated rabbit plasma (0.2 mL) was injected intracamerally following paracentesis, resulting in fibrin clot formation within three hours. The fibrin clots were stable for four days, and then slowly lysed over the next four days. Approximately 24 hours after clot formation, various concentrations of human tPA were injected intracamerally. The time taken for clot lysis was dose dependent, with 1800 IU of tPA producing clot lysis in three hours. Toxicity, as measured by intraocular pressure, corneal thickness, inflammation, or cataract formation, was minimal.
