Experience with the P.A.S.-PORT Venous Access Device in Patients with Gynecologic Malignancies

Experience with the P.A.S.-PORT, a peripherally implanted central venous access device, is evaluated in a retrospective review of 154 patients from July 1991 to June 1994. Blood could not be aspirated from six patients. Complications included temporary minor thrombophlebitis in seven patients (4.5%), symptomatic axillary or subclavian vein thrombosis in five patients (3.2%), clotted port in two patients (1.2%), port pocket cellulitis in two patients (1.2%), and fungal sepsis in two patients (1.2%). In six patients (3.8%) the P.A.S.-PORT had to be removed because of complications. The P.A.S.-PORT facilitated delivery of chemotherapy, parenteral nutrition, blood products, antibiotics, hydration, and blood sampling. It was demonstrated that the P.A.S.-PORT may be inserted and used with a low incidence of complications in gynecologic cancer patients.     

Psychological morbidity after myocardial infarction in an area of deprivation in the UK: evaluation of a self-help package.

BACKGROUND: Psychological morbidity after an acute myocardial infarction (AMI) is known to be common, but can be addressed by appropriate rehabilitation. The area in which this research was conducted experiences high rates of deprivation and of coronary heart disease and limited access to hospital-based rehabilitation. Responding to concern about psychological needs of AMI patients, a self-help package was introduced and evaluated alongside standard hospital-based cardiac rehabilitation. AIMS: To evaluate the impact of a home-based self-help package (the Heart Manual), alongside existing cardiac rehabilitation provision, on psychological morbidity and health status after AMI. A secondary aim was to assess the suitability of the Heart Manual for older patients aged over 80 years. METHODS: A controlled observational study, comparing two cohorts of patients discharged from hospital after AMI. The intervention group was given the self-help package in addition to standard care. The control group received standard care alone. Outcome measures used were the Hospital Anxiety and Depression Scale and the EuroQol. RESULTS: The intervention group showed significant improvement in anxiety and depression scores after 3 months and nonsignificant improvement in general health status. Patients who attended hospital-based rehabilitation classes, and those aged over 80 years, also benefited from the intervention. CONCLUSION: A home-based self-help rehabilitation package is an effective tool alongside hospital-based rehabilitation classes and can be given to all age groups.     

Combination of intermittent haemodialysis and high-volume continuous haemofiltration for the treatment of severe metformin-induced lactic acidosis.

Sir, Metformin has been used for many decades as an effective glucose-loweringmedication in the treatment of type 2 diabetes mellitus. Recentstudies clearly demonstrated that metformin reduced secondarycomplications of diabetes mellitus type 2 without promotingweight gain, which is in contrast to treatment with insulinand/or sulphonylurea [1]. Lactic acidosis is a serious sideeffect observed with metformin treatment and     

Modified extravesical ureteral reimplantation in pediatric renal transplantation: 5 years of experience.

Numerous surgical procedures have been described to reimplant the ureter into the bladder during renal transplantation. Since November 1985 we have used a modified extravesical technique in 19 children. At the time of transplantation patient age ranged from 2 to 17 years (average age 10 years). Of these patients only 2 received a cadaveric kidney. Postoperative followup ranged from 4 to 54 months (average 32 months). No immediate or delayed urological complications were noted, and all but 1 graft has continued to function. This procedure is not only expeditious and safe but it also eliminates a long cystostomy suture line and requires a short ureteral length. Urinary leakage and ureteral obstruction, 2 of the most common urological complications, have not been observed in our patients. Although further experience and longer followup are required, this technique has become our procedure of choice for ureteral reimplantation in children undergoing renal transplantation.     

Factors predicting a successful outcome after pharmacologic bowel compensation.

OBJECTIVES: The authors determined those factors that predict a successful outcome in patients who receive pharmacologic agents to promote bowel absorption after massive intestinal resection. SUMMARY BACKGROUND DATA: Patients with the short bowel syndrome are maintained on long-term total parenteral nutrition (TPN) or more frequently considered for intestinal transplantation as part of their treatment program. The authors have administered a combination of trophic agents and a specialized diet to further enhance intestinal compensation and optimize nutrient absorption in patients with intestinal failure. METHODS: Forty-five TPN-dependent adults with a jejunal-ileal remnant < or = 50 cm and a portion of colon in continuity were treated with growth hormone, glutamine, and a modified diet for 4 weeks and observed for an average of 1.8 years. RESULTS: The average age of the patients was 43 years, the average jejunal-ileal length was 23 cm, and the average length of time the patient received TPN was 4.3 years. After 4 weeks of therapy, 26 (58%) were free of TPN support. Predictors of a favorable response included greater bowel length, lower body weight, and greater bowel length-body weight ratio. At follow-up, the percentage of patients who were not receiving TPN had fallen to 40%. CONCLUSIONS: Approximately half of a group of patients, thought to have absorptive surface area inadequate to be independent of TPN support, can maintain themselves on enteral feedings after this intestinal rehabilitation program. Because of the risk, costs, and alterations in lifestyle associated with long-term TPN or intestinal transplantation or both, it seems prudent to consider a program of bowel rehabilitation with an individual patient before embarking on another therapeutic plan.     

Adult outcomes of attention deficit hyperactivity disorder and conduct disorder: are the risks independent or additive?

METHODS: Data were obtained from a longitudinal study sample of 754 adoptees and categorized based on review of the available adoption agency, medical, and psychiatric records of the biological parents. Categorical data were analyzed using chi2 or Fisher's exact tests, as appropriate. Logistic regression analyses were used to assess the relative contribution of variables. RESULTS: There was not a statistically significant difference in the frequency or type of self-reported adult disruptive behavior, arrests, jail stays, felony arrests, or frequency of conduct disorder (CD) when inattentiveness, impulsivity, and hyperactivity were analyzed individually. The contributions of attention deficit hyperactivity disorder (ADHD) were independent and no additional increased risk for future illegal behavior was conferred by the combination of the disorders. While the effect of CD on illegal behavior was correlated with substance abuse and dependence, ADHD continued to be a significant contributor after controlling for substance abuse and dependence. CONCLUSIONS: Data indicated that ADHD and CD are related but different disorders conferring risk for adult illegal behavior or arrest. In this sample, inattention was the most common domain impaired among those with ADHD, followed closely by hyperactivity, with impulsivity reported least often among those endorsing symptoms of ADHD.

Asymmetric and Axisymmetric Constant Curvature Liquid-Gas Interfaces in Pulmonary Airways

Airway closure and gas trapping can occur during lung deflation and inflation when fluid menisci form across the lumina of respiratory passageways. Previous analyses of the behavior of liquid in airways have assumed that the airway is completely wetted or that the contact angle of the liquid-gas interface with the airway wall is 0, and thus that the airway fluid forms an axisymmetric surface. However, some investigators have suggested that liquid in the airways is discontinuous and that contact angles can be as high as 67. In this study we consider the characteristics of constant curvature surfaces that could form a stable liquid-gas interface in a cylindrical airway. Our analysis suggests that, for small liquid volumes, asymmetric droplets are more likely to form than axisymmetric toroids. In addition, if the fluid contact angle is greater than 13, asymmetric droplets can sustain larger liquid volumes than axisymmetric toroids before collapsing to form menisci. These results suggest that (1) fluid formations other than axisymmetric toroids could occur in the airways; and (2) the analysis of the behavior of fluids and the development of liquid menisci within the lungs should include the potential role of asymmetric droplets.
