Detection of Chlamydia trachomatis in first catch urine samples from symptomatic and asymptomatic males.

BACKGROUND AND OBJECTIVES: Non-invasive tests are needed to detect Chlamydia trachomatis in the genital tract. For men, urine appears to be a useful specimen for chlamydial antigen or nucleic acid detection. GOAL OF THIS STUDY: To evaluate enzyme immunoassays (EIA) for chlamydial antigens in first catch urine (FCU) from symptomatic and asymptomatic men. STUDY DESIGN: We conducted five different studies; FCUs and urethral swabs were collected from 1,341 symptomatic and 816 asymptomatic males. Four EIAs (SureCell, Chlamydiazyme, MicroTrak and IDEIA) were tested on the FCU sediments. RESULTS: Prevalence of chlamydia by tissue culture isolation was 6% for asymptomatic and 14% for symptomatic men. With symptomatic males, the EIA sensitivities and specificities were: SureCell 85% and 97%, IDEIA 82% and 98%, MicroTrak 86% and 99%, and Chlamydiazyme 91% and 95%. For asymptomatic men, Chlamydiazyme sensitivity was 35% with frozen urine vs 77% with fresh urine. Overall, tissue culture sensitivity was about 90%. CONCLUSION: EIA results on FCU sediments are comparable to that of tissue culture isolation on urethral swabs. In many settings, FCU may be the specimen of choice for diagnosing chlamydial infections in men.

The efficacy of anterior cervical plating in the management of symptomatic pseudoarthrosis of the cervical spine.

STUDY DESIGN: A retrospective review of 16 consecutive patients treated with anterior resection of the pseudoarthrosis, autogenous iliac crest bone grafting, and stabilization with an anterior cervical plate. OBJECTIVES: To determine the efficacy of anterior cervical plating used to manage symptomatic pseudoarthrosis of the cervical spine and obtain safe radiographic fusion and improved clinical results. SUMMARY OF BACKGROUND DATA: It is generally recognized that the clinical outcome of anterior cervical discectomy and fusion correlates with rates of fusion. There is debate in the literature as to how the patient with symptomatic cervical pseudoarthrosis should be addressed. Recent reports would support a posterior approach rather than a revision anterior approach. METHODS: Sixteen consecutive patients with symptomatic pseudoarthrosis of the cervical spine were treated with anterior resection of the pseudoarthrosis, autogenous iliac crest bone grafting, and stabilization with an anterior cervical plate. The average follow-up period was 51 months, and patients were assessed using physical examinations, questionnaires, and flexion-extension lateral radiographs. RESULTS: In all, 75% of the patients reported improvement of their symptoms, and 69% of patients returned to work. Fusions were graded I or II in 81% of the patients. No patient demonstrated radiographic instability, and none required revision surgery. Involvement with workers' compensation litigation negatively affected the clinical outcome. CONCLUSIONS: Patients in whom symptomatic cervical pseudoarthrosis develops after cervical anterior discectomy and fusion may be managed successfully with anterior resection of the pseudoarthrosis, autogenous bone grafting, and an anterior cervical plate. Successful clinical results regarding return to work status and general satisfaction with the surgical procedure depend not only on obtaining a successful radiographic fusion, but also on patient selection.

Surgical management of symptomatic spinal metastases. Postoperative outcome and quality of life.

STUDY DESIGN: Eighty-six surgical interventions in 76 consecutive patients with symptomatic spinal metastases were reviewed retrospectively. OBJECTIVES: To evaluate the postoperative outcome and quality of life of patients surgically treated for symptomatic spinal metastases. SUMMARY OF BACKGROUND DATA: The standard surgical treatment for patients with symptomatic spinal metastases is anterior spinal cord decompression with stabilization. However, because therapy is only palliative, satisfactory quality of life and high patient acceptance are essential. METHODS: The medical records of all patients were reviewed retrospectively. Furthermore, all surviving patients or the next of kin of deceased patients were interviewed by telephone, and the family doctors or the care-providing physicians of external institutions were contacted. RESULTS: First-choice surgical treatment was anterior spinal cord decompression with stabilization. Postoperative mean survival was 13.1 months, and mean time at home after spinal surgery was 11.1 months. Neurologic improvement with regard to Frankel classification was observed in 58% of the patients, and 93% were able to walk postoperatively. Pain relief was noted in 89%. Overall, 67% of the patients achieved moderate or good general health as shown by the Karnofsky Index, and 80% were satisfied or very satisfied with the surgical intervention. Moreover, 19% of the surgical interventions were associated with complications, local tumor recurrence developed in 22% of the patients, and paraplegia ultimately developed in 18% of patients. CONCLUSIONS: Surgical management of symptomatic spinal metastases, in particular anterior decompression, is of benefit in most metastatic lesions in terms of satisfactory postoperative outcome and quality of life. However, in patients with melanoma or lung carcinoma, the authors advocate spinal surgery only in very exceptional cases.

Diagnosis of symptomatic disc by magnetic resonance imaging: T2-weighted and gadolinium-DTPA-enhanced T1-weighted magnetic resonance imaging.

Although radial tear of the annulus fibrosus can be detected on T2-weighted and Gd-DTPA-enhanced magnetic resonance (MR) images, the association between the annular tear on MR images and the symptomatic discs is unclear. The purpose of this study was to investigate the relationship between T2-weighted, gadolinium-DTPA-enhanced MR images and pain response through discography in patients with chronic low back pain. A total of 56 lumbar discs from 23 patients with chronic low back pain (13 to 47 years old) underwent MR imaging (T2-weighted, gadolinium-DTPA-enhanced MR images) followed by provocative discography. The sensitivity, specificity, positive predictive value, and negative predictive value of T2-weighted and gadolinium-DTPA-enhanced MR images in detecting the symptomatic discs were calculated. The sensitivity, specificity, positive predictive value, and negative predictive value of T2-weighted images in detecting the symptomatic disc were 94%, 71%, 59%, and 97%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of gadolinium-DTPA-enhanced images were 71%, 75%, 56%, and 86%, respectively. The high sensitivity and the high negative predictive value of T2-weighted MR imaging in detecting the symptomatic disc indicated that MR imaging can be a useful screening tool in avoiding unnecessary discography in patients with chronic low back pain.

Core body temperature variation in symptomatic and asymptomatic postmenopausal women: brief report.

OBJECTIVE: To determine if core body temperature (T) fluctuations occur in asymptomatic as well as symptomatic postmenopausal women. DESIGN: Tc was recorded with an ingested radiotelemetry pill in symptomatic postmenopausal women who had a hot flash in the laboratory, in symptomatic women who did not have a hot flash in the laboratory, and in asymptomatic postmenopausal women. RESULTS: There were no significant differences in mean Tc or Tc variation, as measured by the standard deviation, among the three groups. CONCLUSION: Tc fluctuations are not unique to symptomatic postmenopausal women.

Evaluation of predive parameters related to eustachian tube dysfunction for symptomatic middle ear barotrauma in divers.

OBJECTIVE: Eustachian tube dysfunction plays an important role in the pathogenesis of middle ear barotrauma. This investigation evaluates the predictive value of several parameters related to tubal dysfunction, in relation to symptomatic middle ear barotrauma in divers. STUDY DESIGN: Prospective and blinded. PATIENTS: Thirty-one sport scuba divers with normal predive audiometry, tympanometry, and general and otorhinolaryngologic examination. METHODS: After an occurrence of middle ear barotrauma, the individual diver predive data on smoking, mild septal deviation, otitis media history, rhinosinusitis history, Valsalva, Toynbee, and nine-step inflation/deflation tympanometric test, as well as degree of mastoid pneumatization were registered for calculation of predictive value in relation to the barotrauma. All symptomatic ears were examined within 24 hours of diving by the investigator, who was blinded to the predive findings. Barotraumas that occurred during an upper respiratory tract infection were excluded. RESULTS: Divers completed a total of 774 dives (median, 25; range, 3-100). Symptomatic middle ear barotrauma occurred in 19 ears (31%) of 14 divers (45%) at one time or another. The rate of tubal dysfunction measured by the nine-step test and a mastoid pneumatization below average were significantly higher in divers (p <0.05) as well as in ears (p <0.005) with barotrauma. Positive and negative predictive values of both parameters for subsequent barotrauma were between 69% and 76%. Combining the results into a two-test battery in a strict approach (positive on both) increased the positive predictive value to 86%. CONCLUSION: Eustachian tube dysfunction measured by the nine-step test and a small size of the mastoid cell system seem to be risk factors for symptomatic middle ear barotrauma in otherwise healthy sport scuba divers. Evaluation of these factors in the predive examination of diving candidates may be useful in the determination of fitness to dive.

Balloon kyphoplasty for symptomatic vertebral body compression fractures results in rapid, significant, and sustained improvements in back pain, function, and quality of life for elderly patients.

STUDY DESIGN: Prospective, single-arm interventional cohort. OBJECTIVE: To evaluate the safety and effectiveness of balloon kyphoplasty to treat symptomatic vertebral body compression fractures (VCFs). SUMMARY OF BACKGROUND DATA: VCFs treated nonoperatively can diminish function and quality of life, and lead to chronic health effects. The short-term safety and effectiveness of balloon kyphoplasty for symptomatic VCFs are well-documented, but long-term follow-up is needed. METHODS: A total of 155 elderly patients with symptomatic VCFs were enrolled in a prospective, multicenter treatment study of balloon kyphoplasty at 19 geographically diverse US centers. Outcomes included back pain severity, bedrest, and limited activities because of back pain, back disability score, and SF-36 Medical Outcomes Survey, at 7 days (visual analog scale only), and 1, 3, 12, and 24 months after treatment. RESULTS: Patients reported severe back pain (15/20 on visual analog scale) interfering with daily activities 90% of days per month before kyphoplasty. Physical functioning and quality of life were also markedly impaired. Statistically significant (P < 0.001) improvements occurred in all pain, functional, and mental health outcomes at the first follow-up after treatment and were maintained for 24 months. CONCLUSIONS: Elderly patients with symptomatic VCFs had rapid, significant, and sustained improvements in back pain, back function, and quality of life following balloon kyphoplasty.

Radiotherapy for symptomatic metastases to bone in children.

Thirty-seven children less than age 19 years were treated from 1985 through 1998 with radiotherapy for symptomatic metastases to bone. The most common primary tumors were neuroblastoma (18), Ewing's sarcoma (5), and osteosarcoma (5). The interval from diagnosis of the primary tumor to treatment of the first symptomatic metastases involving bone ranged from 0 to 163 months (median 19). Thirty-seven children were treated with 150 courses of radiotherapy. Forty-three courses consisted of a single dose of 300 to 1,000 cGy. One hundred thirteen courses of radiotherapy consisted of five or fewer treatment fractions. Sixteen osseous sites were treated with two courses of radiotherapy and two sites were treated with three. The most commonly irradiated symptomatic bone sites were skull, spine, and hip/femurs. Survival from the first course of radiotherapy administered for metastases to bone varied from 1 to 52 months, with 11 patients (29.7%) surviving 12 or more months and only 3 patients (8.1%) surviving more than 2 years. The majority of children seemed to derive palliation from the radiotherapy based on assessment by family and medical personnel as well as by self-report in older patients. Children with symptomatic metastases to bone have an extremely poor prognosis, and short courses of radiotherapy are suggested as palliation. Repeat courses of radiotherapy can be given for persistent or recurrent symptoms.

Association of prostatic inflammation with down-regulation of macrophage inhibitory cytokine-1 gene in symptomatic benign prostatic hyperplasia.

PURPOSE: Our previous DNA microarray analyses revealed that the macrophage inhibitory cytokine-1 (MIC-1) gene was significantly down-regulated in symptomatic benign prostatic hyperplasia (BPH) samples. We compared the histopathological features of inflammatory changes in prostate adenoma tissues from individuals with symptomatic and asymptomatic (histological only) BPH using MIC-1 mRNA levels. MATERIALS AND METHODS: Prostate adenoma tissues were obtained from 25 patients who underwent transurethral prostatectomy to relieve lower urinary tract symptoms due to BPH and 6 patients with bladder cancer who underwent cystoprostatectomy due to bladder cancer. Inflammatory changes in the prostate were examined histopathologically and immunohistochemically, and classified according to the consensus classification system of the Chronic Prostatitis Collaborative Research Network and International Prostatitis Collaborative Network advocated in 2001 with some modification. MIC-1 mRNA was assessed quantitatively by real-time reverse transcriptase-polymerase chain reaction. RESULTS: MIC-1 gene down-regulation was observed in 16 of 25 symptomatic BPH samples (64.0%), whereas MIC-1 mRNA was high in 6 of 6 prostate adenoma samples from patients with bladder cancer (p = 0.0006). MIC-1 gene down-regulation correlated with the grade of glandular/ periglandular inflammatory changes with statistical significance (p = 0.0387). MIC-1 gene down-regulation was found in only 1 of 7 BPH samples with a glandular predominant pattern, whereas it was found in 15 of 24 BPH samples with a mixed type or stromal predominant pattern (p = 0.0373). CONCLUSIONS: Gland destruction by inflammatory infiltrates, followed by replacement of the stromal component in symptomatic BPH may be induced by the down-regulation of the MIC-1 gene.

Laparoscopic management of symptomatic and large adrenal cysts.

PURPOSE: We present the feasibility and results of the laparoscopic management of symptomatic and large adrenal cysts. MATERIALS AND METHODS: From June 1993 to April 2004 we performed 149 laparoscopic adrenalectomies. In this series 8 patients with symptomatic adrenal cysts or pseudocysts were treated laparoscopically. Surgical indications for laparoscopic management of adrenal cysts were abdominal pain in 5 cases and cyst size 5 cm or greater in 3. RESULTS: The incidence of adrenal cyst was 5.4% (8 of 149 cases). Six patients underwent laparoscopic adrenal cyst decortication and marsupialization, 1 underwent laparoscopic partial adrenalectomy and 1 underwent laparoscopic adrenalectomy. Mean operative time was 77.5 minutes. There were no intraoperative or postoperative complications. Mean hospital stay was 1.7 days. At a mean followup of 18.5 months all patients were asymptomatic and without radiographic evidence of cyst recurrence. CONCLUSIONS: Laparoscopic conservative management of adrenal cysts is safe and feasible. Laparoscopic decortication and marsupialization should be the preferred treatment option for symptomatic adrenal cysts. Laparoscopic partial adrenalectomy or a total adrenalectomy can be performed in cases of larger cysts which compromise most of the adrenal gland. To our knowledge, this represents the largest series of symptomatic adrenal cysts managed laparoscopically.

Phylogenetic analysis of bacterial and archaeal species in symptomatic and asymptomatic endodontic infections.

Phylogenetic analysis of bacterial and archaeal 16S rRNA was used to examine polymicrobial communities within infected root canals of 20 symptomatic and 14 asymptomatic patients. Nucleotide sequences from approximately 750 clones amplified from each patient group with universal bacterial primers were matched to the Ribosomal Database Project II database. Phylotypes from 37 genera representing Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria and Proteobacteria were identified. Results were compared to those obtained with species-specific primers designed to detect Prevotella intermedia, Porphyromonas gingivalis, Porphyromonas endodontalis, Peptostreptococcus micros, Enterococcus sp., Streptococcus sp., Fusobacterium nucleatum, Tannerella forsythensis and Treponema denticola. Since members of the domain Archaea have been implicated in the severity of periodontal disease, and a recent report confirms that archaea are present in endodontic infections, 16S archaeal primers were also used to detect which patients carried these prokaryotes, to determine if their presence correlated with severity of the clinical symptoms. A Methanobrevibacter oralis-like species was detected in one asymptomatic and one symptomatic patient. DNA from root canals of these two patients was further analysed using species-specific primers to determine bacterial cohabitants. Trep. denticola was detected in the asymptomatic but not the symptomatic patient. Conversely, Porph. endodontalis was found in the symptomatic but not the asymptomatic patient. All other species except enterococci were detected with the species-specific primers in both patients. These results confirm the presence of archaea in root canals and provide additional insights into the polymicrobial communities in endodontic infections associated with clinical symptoms.

Thallium scintigraphy in prediction of occlusion of bypass grafts in asymptomatic and symptomatic patients.

To evaluate thallium scintigraphy in predicting coronary artery bypass graft patency, exercise thallium scintigraphy and selective graft and native vessel angiograms were performed in 22 asymptomatic and 29 symptomatic consecutive patients three months after coronary artery bypass grafting (CABG). Twelve out of 22 asymptomatic patients (55%) had reversible thallium defects on postoperative images; in 10 patients the postoperative scans were normal. The graft patency was significantly lower in asymptomatic patients with abnormal thallium perfusion compared to those with normal perfusion after CABG (68% vs. 91%, p less than 0.05). The rate of graft patency in symptomatic patients was 66/87 (76%). Thallium scintigraphy was 77% sensitive and 78% specific in detecting one or more stenosed or occluded bypass grafts in patients without angina (accuracy 77%). When data from exercise electrocardiography were combined with scintigraphy, all but one patient with incomplete revascularization could be detected (positive predictive accuracy 92%). In symptomatic patients, thallium scintigraphy accurately predicted the presence or absence of graft occlusion in 24/29 (83%) cases. Thus, abnormal myocardial perfusion due to stenosis or occlusion of bypass grafts is common in both asymptomatic and symptomatic patients after CABG. Thallium scintigraphy together with exercise electrocardiography appear to be useful non-invasive methods in detecting painless myocardial ischemia and in predicting bypass graft occlusion after CABG.

Efficacy of rifaximin in the treatment of symptomatic diverticular disease of the colon. A multicentre double-blind placebo-controlled trial.

BACKGROUND AND AIMS: In a recent open trial we have shown the efficacy of long term intermittent administration of a poorly absorbable antibiotic (rifaximin) in obtaining symptomatic relief in uncomplicated diverticular disease of the colon. The aim of this double-blind placebo-controlled trial was to test our previous observations. METHODS: One hundred and sixty-eight outpatients with symptomatic uncomplicated diverticular disease were treated with fibre supplementation (glucomannan 2 g/day) plus rifaximin 400 mg b.d. for 7 days every month (84 patients), or with glucomannan 2 g/day plus placebo two tablets b.d. for 7 days every month (84 patients). Clinical evaluation was performed at admission and at three-month intervals for 12 months. RESULTS: After 12 months, 68.9% of the patients treated with rifaximin were symptom-free or mildly symptomatic, compared to 39.5% in the placebo group (P = 0.001). Symptoms such as bloating and abdominal pain or discomfort were primarily affected by antibiotic treatment when compared with placebo (P < 0.001). CONCLUSION: Rifaximin appears to be of some advantage in obtaining symptomatic relief in diverticular disease of the colon when compared with fibre supplementation alone.

Long-term treatment of gastro-oesophageal reflux disease patients with frequent symptomatic relapses using rabeprazole: on-demand treatment compared with continuous treatment.

BACKGROUND: On-demand treatment may be an alternative in the long-term treatment of non-severe gastro-oesophageal reflux disease in patients with frequent symptomatic relapses. AIM: To compare the efficacy of on-demand treatment with rabeprazole 10 mg versus continuous treatment in the long-term treatment of patients with frequent symptomatic relapses of mild to moderate gastro-oesophageal reflux disease. METHODS: This randomized, open-label study enrolled patients diagnosed with non-erosive reflux disease or oesophagitis grade 1 or 2 (Savary-Miller classification) reporting frequent symptomatic relapses (requiring > or =2 courses of antisecretory therapy during the previous year), whose intensity is rated at least moderate (>2 on a 5-point Likert scale). After a 4-week selection phase with rabeprazole 10 mg once daily, patients reporting symptom relief (Likert score < or =2) were randomized to receive either rabeprazole 10 mg continuous treatment or on-demand treatment for 6 months. The main evaluation criterion was the rate of symptom relief (scored on the Likert scale) after 6 months. RESULTS: One hundred and seventy-six patients were enrolled in the 4-week selection phase (men, 53%; mean age, 49 years; non-erosive reflux disease, 36.4%; gastro-oesophageal reflux disease 1, 53.4%; gastro-oesophageal reflux disease 2, 10.2%). Rabeprazole relieved symptoms in 88.6% of patients. Of this group, 152 were randomized to the comparative phase to receive rabeprazole 10 mg continuous treatment (once daily) or on-demand treatment (continuous treatment, n = 81; on-demand treatment, n = 71). At month 6 (end point), the symptom relief rate was slightly higher for patients in the continuous treatment group compared with those in the on-demand treatment group: 86.4% versus 74.6%, respectively. This difference was not statistically significant (P = 0.065). For the overall quality of life score, there was no difference between the continuous treatment and on-demand treatment groups (86.25 and 84.94). Mean daily consumption of rabeprazole was significantly lower in the on-demand treatment group versus the continuous treatment group (0.31 tablets versus 0.96 tablets; P < 0.0001). CONCLUSION: On-demand therapy with rabeprazole 10 mg provides an alternative to continuous therapy in patients with mild to moderate gastro-oesophageal reflux disease suffering from frequent symptomatic relapses.

A prospective observational study of a cohort of outpatients with an acute medical event and reduced mobility: incidence of symptomatic thromboembolism and description of thromboprophylaxis practices.

OBJECTIVES: The study was performed to determine the incidence of symptomatic venous thromboembolism in outpatients with an acute medical event causing temporary reduced mobility. Risk factors for venous thromboembolism and thromboprophylaxis practices were also studied. DESIGN: This was a prospective, observational, multicentre, cohort study. SETTING: General practitioners randomly selected from a registry of 25,000 active representative doctors in France including eligible outpatients. SUBJECTS: Outpatients aged at least 40 years anticipated to have reduced mobility for at least 48 h due to an acute medical event were eligible. INTERVENTIONS: None required. MAIN OUTCOME MEASURES: Symptomatic deep-vein thrombosis and pulmonary embolism at 3 weeks were the main study end-points. RESULTS: Overall, 16,532 evaluable patients of mean age 71 years were recruited between October 2002 and June 2003 by 2895 doctors. The main acute medical events leading to reduced mobility were infection, acute rheumatism and falls without fracture. The incidence rates (95% confidence interval) of symptomatic deep-vein thrombosis and pulmonary embolism were 1% (0.84-1.14) and 0.20% (0.13-0.27) respectively. Venous insufficiency in legs, cancer, and a personal or family history of venous thromboembolism were independent risk factors for venous thromboembolism. Pharmacological thromboprophylaxis was initiated in 35.0% (n=5782) of the patients. The principal driver of prescription was a personal history of venous thromboembolism. CONCLUSIONS: The risk of symptomatic venous thromboembolism in outpatients with reduced mobility for medical reasons is close to that reported in medical and surgical inpatients. This risk and the potential need for thromboprophylaxis should be taken into account by primary care doctors.

Symptomatic and functional outcome 12 months after a first episode of psychotic mania: barriers to recovery in a catchment area sample.

OBJECTIVE: Recent studies have shown that outcome in mania is worse than previously thought. Such studies have been conducted in selected samples with restrictive measures of outcome. We aimed to explore outcome and its predictors in a catchment area sample of first-episode psychotic mania of DSM-III-R bipolar I disorder. METHODS: Prospective 6 and 12 months follow-up was conducted with 87 DSM-III-R first-episode psychotic mania patients admitted to Early Psychosis Prevention and Intervention Centre between 1989 and 1997. Syndromic and symptomatic outcome were determined with the Brief Psychiatric Rating Scale; functional outcome with the Quality of Life Scale and Premorbid Adjustment Scale subitems. RESULTS: Symptomatic outcome was assessed in 67 patients at 6 months and 61 patients at 12 months, and functional outcome in 56 patients at 6 months and 49 patients at 12 months. Logistic regressions were conducted on 46 and 43 patients, respectively, to explore predictors of outcome. While 90% of patients achieved syndromic recovery at 6 and 12 months, 40% had not recovered symptomatically at 6 and 12 months, still presenting with anxiety or depression. A total of 66% of patients at 6 months and 61% of patients at 12 months failed to return to previous level of functioning. Age at intake, family history of affective disorder, illicit drug use and functional recovery at 6 months predicted functional outcome at 12 months. CONCLUSIONS: This study confirms poor symptomatic and functional outcome after first-episode psychotic mania. It suggests possible usefulness of early intervention strategies in bipolar disorders and need for developing specific interventions addressing anxiety, depression and substance abuse comorbidity.

Prevalence of symptomatic large pleural effusions first diagnosed more than 30 days after coronary artery bypass graft surgery.

BACKGROUND AND OBJECTIVE: Symptomatic large pleural effusions (>25% of hemithorax) are sometimes diagnosed after coronary artery bypass graft surgery (CABG). Their incidence and outcome have not been fully described. This study aims to discuss the prevalence and the clinical course in patients diagnosed with symptomatic newly developed large pleural effusions at least 30 days after CABG. METHODS: A retrospective study of 410 patients who underwent CABG over a three and a half year period was undertaken. The type of surgery, timing of occurrence of effusion after CABG, amount and characteristics of the pleural effusion, left ventricular dimension and ejection fraction were obtained from medical records and cardiac surgery databases. RESULTS: The records of 356 patients 1 month post CABG were available for evaluation. The initial diagnosis of a newly developed symptomatic large pleural effusions was made in 11 patients (3.1%) at least 30 days after CABG. Eight had a pleural effusion predominantly on the left side and three on the right. Patients were further divided into two groups: those who had effusions diagnosed between 30 and 90 days post CABG (group 1) and those diagnosed more than 90 days post-CABG (group 2). The pleural fluid LDH levels were higher in patients in group 1 (1262.0 +/- 921.3 U/L vs. 117.5 +/- 35.1 U/L, P = 0.02). Patients in group 2 had evidence of cardiac impairment compared with those in group 1, as evidenced by a lower ejection fraction (68.8 +/- 6.0% vs. 52.0 +/- 10.6% in groups 1 and 2, respectively, P = 0.01) and higher left ventricular end-diastolic dimension (45.2 +/- 6.0 mm vs. 55.3 +/- 8.4 mm in groups 1 and 2, respectively, P = 0.05). CONCLUSIONS: The incidence of symptomatic newly developed large pleural effusions first diagnosed at more than 30 days post CABG was 3.1%. Those who were diagnosed between 30 and 90 days post CABG tended to have exudative effusions, whereas those diagnosed more than 90 days post CABG often had left ventricular impairment and transudative effusions. Most of these effusions settled with conservative management and did not recur.

Perhexiline improves symptomatic status in elderly patients with severe aortic stenosis.

BACKGROUND: The prognosis of severe symptomatic aortic stenosis is poor without aortic valve replacement, with no previous reports of beneficial effects of any medical treatment on either symptoms or outcome. However, this condition is increasingly a disease of the elderly and cardiothoracic surgery is associated with significant mortality and morbidity in this group. AIMS: We postulated that perhexiline, a novel anti-ischaemic agent with an oxygen-sparing metabolic effect in the myocardium (via inhibition of carnitine palmitoyltransferase-1) and no adverse haemodynamic effects, may improve symptomatic status in elderly patients with severe aortic stenosis. We report here our initial experience with perhexiline treatment in such patients. METHODS: Elderly patients with symptomatic severe aortic stenosis, who were deemed unsuitable for aortic valve replacement, were treated with perhexiline, the drug dosage titrated according to steady state plasma perhexiline concentrations. NYHA functional class was determined prior to and three months following commencement of perhexiline, and changes were analysed using McNemar's test. RESULTS: Fifteen patients, age range 73-87, were followed for up to 30 months (median 18 months). Symptomatic status improved in 13 of the 15 patients over the first three months of perhexiline therapy (p < 0.01), five patients becoming asymptomatic. Twelve month actuarial survival was 80% (95% CI = 57, 100). Perhexiline was well tolerated, with no withdrawals due to toxicity or deteriorating clinical status. CONCLUSION: Therapy with perhexiline was associated with a marked improvement in clinical status in this group of elderly patients with severe aortic stenosis.
