Abstract
Electroconvulsive therapy (ECT) is considered to be one of the most effective treatments for patients with major depression and persistent psychosis. Seizure characteristics probably determine the therapeutic effect of ECT; as a consequence, short seizures are accepted as one of the factors of poor outcome. During most ECT courses seizure threshold increases and seizure duration decreases. Methylxanthine preparations, caffeine, and theophylline have been used to prolong seizure duration. The use of aminophylline, more readily available than caffeine, has not been well documented. The objective of this study was to test the effects of aminophylline on seizure length. Fourteen drug-free patients with diagnoses of affective disorder or psychotic episode receiving ECT participated in this study. Seizure length was assessed clinically and per EEG. Statistical comparisons were done using paired t tests. A significant increase (p < 0.04) in seizure length was achieved and maintained on three subsequent treatments with aminophylline. No adverse events were noted from the addition of aminophylline.

Abstract
An automated early warning system has been developed and used for detecting clusters of human infection with enteric pathogens. The method used requires no specific disease modelling, and has the potential for extension to other epidemiological applications. A compound smoothing technique is used to determine baseline 'normal' incidence of disease from past data, and a warning threshold for current data is produced by combining a statistically determined increment from the baseline with a fixed minimum threshold. A retrospective study of salmonella infections over 3 years has been conducted. Over this period, the automated system achieved > 90% sensitivity, with a positive predictive value consistently > 50%, demonstrating the effectiveness of the combination of statistical and heuristic methods for cluster detection. We suggest that quantitative measurements are of considerable utility in evaluating the performance of such systems.

Abstract
The serotonergic system has been implicated in both the aetiology and pharmacological treatment of obsessive compulsive disorder. In pharmacological challenge tests, mCPP, a 5-HT agonist, with an affinity for 5HT2C as well as 5HT1A and 5HT1D receptors, was associated with a transient exacerbation of obsessive compulsive symptoms. Chronic administration of mCPP was found to bring about some relief of these symptoms. Sumatriptan is an antimigraine agent, which interacts most potently with 5HT1D receptors. In the cases to be presented, we report the effects of chronic administration of Sumatriptan to three severe, treatment resistant, OCD patients. Following chronic administration of sumatriptan, these patients, who have been resistant to any former pharmacological treatment, responded with an improvement in their depression and a modest reduction in their obsessive compulsive symptoms.

Abstract
OBJECTIVE Subarachnoid hemorrhage (SAH) predisposes patients to excessive natriuresis and volume contraction. We studied the effects of postoperative administration of 5% albumin solution on sodium balance and blood volume after SAH. We also sought to identify physiological variables that influence renal sodium excretion after SAH. METHODS Forty-three patients with acute SAH were randomly assigned to receive hypervolemia or normovolemia treatment for a period of 7 days after aneurysm clipping. In addition to a base line infusion of normal saline solution (80 ml/hr), 250 ml of 5% albumin solution was administered every 2 hours for central venous pressure (CVP) values of < or =8 mm Hg (hypervolemia group, n = 19) or < or =5 mm Hg (normovolemia group, n = 24). RESULTS Both groups demonstrated relative volume expansion in base line measurements. The hypervolemia group received significantly more total fluid, sodium, and 5% albumin solution than did the normovolemia group and had higher CVP values and serum albumin levels (all P < 0.02). Cumulative sodium balance was even in the hypervolemia group and persistently negative in the normovolemia group, because of sodium losses that occurred on Postoperative Days 2 and 3 (P = 0.03). In a multiple-regression analysis of all patients, 24-hour sodium balance correlated negatively with glomerular filtration rate (GFR) and positively with serum albumin levels, after correction for sodium intake (P < 0.0001). Hypervolemia therapy seemed to paradoxically lower GFR (P = 0.10) and had no effect on blood volume, which declined by 10% in both groups. Pulmonary edema requiring diuresis occurred in only one patient in the hypervolemia group. CONCLUSION Supplemental 5% albumin solution given to maintain CVP values of >8 mm Hg prevented sodium and fluid losses but did not have an impact on blood volume in our patients, who were hypervolemic in base line measurements. The natriuresis that occurs after SAH may be mediated in part by elevations of GFR. In addition to acting as a colloid volume expander, 5% albumin solution lowers the GFR and promotes renal sodium retention after SAH. These properties may limit the amount of total fluid required to maintain a given CVP value and hence may minimize the frequency of pulmonary edema.

Abstract
Electroconvulsive therapy (ECT) in patients with impaired cardiac output may be associated with significant cardiovascular morbidity and mortality because of its hemodynamic effects. Many clinicians are reluctant to treat these patients with ECT because of the high risk associated with the treatment. In this report, we present a clinically appropriate protocol for ECT treatment of patients with impaired cardiac output and major depressive disorder. Three patients, ages 59-78 years, with resistant major depression and impaired cardiac output (ejection fraction 20-25%), were successfully treated with ECT according to this protocol.

Abstract
BACKGROUND An increased risk of anogenital tract malignancies has been noted among renal transplant recipients. A high prevalence of human papillomavirus (HPV) infection of the cervix in the female renal-transplant population has been assumed based on increasing evidence suggesting that HPV infection is the major risk factor for cervical intraepithelial neoplasia (CIN) and cervical cancer. It has been assumed that immunosuppression leads to either a reactivation of latent HPV or a reduction in the host's ability to contain a primary HPV infection, thereby increasing the risk of CIN and cervical cancer. The objective of this study was to evaluate the prevalence of human papillomavirus (HPV) infection in a population of iatrogenically immunosuppressed renal transplant recipients. METHODS Twenty-one women were recruited from the renal transplant clinic at Presbyterian Hospital and underwent a gynaecological examination which included colposcopy, a Papanicolaou smear, and a cervicovaginal lavage. Lavage samples were analysed for HPV DNA using L1 consensus primers and the polymerase chain reaction (PCR). RESULTS No cases of cervical intraepithelial neoplasia (CIN) were detected in this cohort of 21 immuno-suppressed renal transplant recipients. HPV DNA was detected in only a single patient. CONCLUSIONS Our data suggests that HPV infection is not highly prevalent among older, cytologically normal renal transplant recipients, particularly those who are currently monogamous or not presently sexually active. This study suggests that recent sexual behaviours are more important than past behaviours as a determinant of HPV status in transplant recipients, and also suggests that education concerning the avoidance of high-risk sexual behaviour is an important part of the care of the female renal transplant recipient. Our data is consistent with previous work suggesting that the incidence of CIN is declining in transplant recipients, and it also suggests that the prevalence of HPV infection may be declining as well.

Abstract
The production of interleukin-2 (IL-2) and interleukin-6 (IL-6) by peripheral blood mononuclear cells (MNC) was assessed in patients with Alzheimer's disease (AD) who were subdivided into two groups--mild and moderately-severe--according to the severity of the disease, probable vascular dementia (VaD) patients and elderly control subjects. No differences in IL-2 secretion were found between mild AD patients and controls. However, there was a significant increase in IL-2 production both in the moderately-severe AD group and in the VaD group. IL-6 levels in AD patients of both groups were similar and significantly higher than those of VaD and controls. Our results suggest that increased levels of IL-2-production correlate with severity of the dementia, whereas increased levels of IL-6 production seem to be related to AD and thus may play a role in AD pathogenesis.

Abstract
It has been suggested in recent research that interleukin-1 (IL-1) and interleukin-6 (IL-6) play a role in the pathogenesis of Alzheimer's disease (AD). Production of IL-1, by lipopolysaccharide (LPS)-stimulated monocytes, and IL-6, by phytohaemagglutinin (PHA)-stimulated mononuclear cells, was assessed in patients with AD divided into two groups--mild and moderately severe--according to severity of disease, and elderly controls. No differences in IL-1 production were found among AD patients and controls. However, significant elevation in IL-6 secretion levels was observed in both the mild and moderately severe AD patients. Our results suggest that peripheral IL-6 secretion levels may be responsible for acute-phase proteins observed in the serum of AD patients.

Abstract
We performed a prospective study to examine the epidemiology and microbiology of peritonitis complicating acute intermittent peritoneal dialysis (IPD) performed in an in-hospital setting for the management of acute and chronic renal failure and to see the effect of a closed-drainage system on altering the frequency and cause of peritonitis. Over a 15-month period, 79 patients were treated with acute IPD for a total of 136 treatments each ranging in length from 2 to 40 days (median, 4 days). The majority of cases had acute renal failure (ARF; 65%) and were treated in intensive care units (ICUs; 74%) with serious comorbid conditions (60%). About half were treated with a two-bag, ventable (open)-drainage system with unprotected spikes, and the other half were treated with a single-bag, spike-protected, closed-drainage system. There were 27 cases of peritonitis for a rate of 4.5 cases/100 patient-days at risk. About half were gram-positive infections; the remainder were gram-negative or mixed (25%) or Candida sp (25%). The use of a closed-drainage system reduced the incidence of system-related peritonitis from 3.6 to 1.5 cases/100 patient-days. There was a high rate of peritonitis in the first 48 hours of treatment, which fell to a low stable rate thereafter and remained so for up to 15 days of continuous IPD. The use of a closed-drainage system eliminated the early (< 48 hours) high rate of peritonitis and maintained a low constant rate of peritonitis throughout treatment. There was an association of ARF and severe comorbid disease with more virulent organisms (gram-negative, mixed, and Candida sp), which, in turn, were both associated with antecedent broad-spectrum antibiotic therapy. Random positive surveillance cultures showed a frequency distribution similar to that of peritonitis cases over the duration of treatment, but with less virulent organisms. Peritonitis in acute IPD occurs when large or repeated inocula of organisms from the prevailing flora overwhelm the peritoneal immune clearance mechanisms. Prolonged courses of broad-spectrum antibiotic therapy provide no protection, but shift the resulting infecting flora toward more virulent pathogens. A closed-drainage system provides one method to reduce the frequency of peritoneal contamination.

Abstract
Epithelial sialomucins constitute a family of high-molecular-weight glycoproteins associated with epithelial cell surfaces. Aberrant expression of these molecules has been observed in certain types of human epithelial tumors. Members of the MUC1 family of mucins isolated from different tissue types have been shown to differ in biochemical properties and in immunological reactivity. The polymerase chain reaction (PCR) has been used in a study of the MUC1 mRNA expressed in ovarian tumor cells. The intron/exon structure of the ovarian mucin gene has been examined, the nucleotide sequence of regions of the cDNA 5' and 3' to a central highly repetitive region of the molecule determined and genomic clones for this mucin from the ovarian tumor cell line COLO316 have been isolated and analyzed. The results are compared with the nucleotide sequence data obtained by others for MUC1 cDNA in breast and pancreatic cell lines. With a single nucleotide exception, the splicing pattern and nucleotide sequence obtained from MUC1 mRNA in the ovarian cell line is the same as that of the mRNA found in breast and pancreatic cell lines. However, it appears that the use of alternate splice acceptors for intron I in the ovarian cell line studied here is independent of the specific sequence variation thought to determine splicing of MUC1 in breast tumor cells.

Abstract
Based on encouraging preliminary findings, cannabidiol (CBD), a major nonpsychotropic constituent of Cannabis, was evaluated for symptomatic efficacy and safety in 15 neuroleptic-free patients with Huntington's Disease (HD). The effects of oral CBD (10 mg/kg/day for 6 weeks) and placebo (sesame oil for 6 weeks) were ascertained weekly under a double-blind, randomized cross-over design. A comparison of the effects of CBD and placebo on chorea severity and other therapeutic outcome variables, and on a Cannabis side effect inventory, clinical lab tests and other safety outcome variables, indicated no significant (p greater than 0.05) or clinically important differences. Correspondingly, plasma levels of CBD were assayed by GC/MS, and the weekly levels (mean range of 5.9 to 11.2 ng/ml) did not differ significantly over the 6 weeks of CBD administration. In summary, CBD, at an average daily dose of about 700 mg/day for 6 weeks, was neither symptomatically effective nor toxic, relative to placebo, in neuroleptic-free patients with HD.

Abstract
Coronary artery disease, overt or silent, is frequently present in patients who have suffered a cerebrovascular accident (CVA). Rehabilitation therapy of CVA patients is based mostly on physical activity, which may be limited by fear of overloading the cardiovascular system. Therefore, assessment of the severity of coronary heart disease in CVA patients is of utmost importance. In this study we assessed the usefulness of 24-hour electrocardiographic Holter monitoring in the evaluation of post-CVA patients during daily activities and rehabilitation. Of the 43 post-CVA patients, 24 (55.8%) revealed pathological changes on Holter monitoring and 17 (71%) had a history of coronary artery disease prior to CVA. Holter monitoring revealed mainly ventricular and atrial arrhythmias and in three patients detected transient ischaemic episodes. Only six patients (14%) showed aggravation of arrhythmia during rehabilitation therapy, without aggravation of ST-T changes. The mean maximum heart rate during regular daily activities was 104 +/- 20 beats/min, which was significantly higher than the mean maximum heart rate during physical therapy (100 +/- 18 beats/min; p less than 0.01) and during occupational therapy (87 +/- 18 beats/min; p less than 0.001). These findings indicate that more vigorous physical and occupational therapy can be prescribed to these patients. The performance of Holter monitoring in post-CVA patients is a valuable substitute to exercise testing, and is useful for cardiovascular evaluation during daily activities and rehabilitation therapy.
