Second-generation antipsychotic exposure and metabolic-related disorders in patients with schizophrenia: an observational pharmacoepidemiology study from 1988 to 2002

Patients with schizophrenia are at increased risk for cardiovascular disease as a consequence of lifestyle habits, impaired access to health care, and, increasingly, due to metabolic side effects ostensibly attributed to second-generation antipsychotics (SGAs). There is little evidence, however, on the extent and temporal patterns of SGA-associated metabolic side effects. We longitudinally examined the differential prevalence rates of obesity, diabetes mellitus, and diabetic ketoacidosis among inpatients with schizophrenia compared with control inpatients without schizophrenia. The data were derived from the National Inpatient Sample, the largest all-payer inpatient care database in the United States consisting of 5 to 8 million inpatient hospital stays per year sampled to approximate a 20% sample of community hospitals from 1988 to 2002. Overlaid on these observations was the market penetration data for SGAs. In 1988, the net difference from controls in obesity prevalence among inpatients with schizophrenia was +4.7%; by 2002, this difference had widened to +14.7%. Similarly, a significant increase in net prevalence of diabetes mellitus and diabetic ketoacidosis was observed from 1988 to 2002 among schizophrenic inpatients. In conclusion, after the introduction of SGAs, patients with schizophrenia in the United States have experienced a striking net increase in the prevalence of obesity and diabetes mellitus. This is likely to significantly add to an already elevated risk for cardiovascular disease in this population. Further investigations are urgently required so that health policy can be appropriately amended for preventive measures.     

Consumption of herbal remedies and dietary supplements amongst patients hospitalized in medical wards

AIMS: Herbal remedies may have adverse effects and potentially serious interactions with some commonly prescribed conventional medications. Little is known about consumption of herbal remedies and dietary supplements by hospitalized patients. The aim was to evaluate the rate of consumption and characterize the patients hospitalized in internal medicine departments who consume herbal remedies and dietary supplements. Also, to assess the medical teams' awareness and assess the percentage of patients with possible drug-herb interactions. METHODS: Patients hospitalized in the medical wards of two hospitals in Israel were interviewed about their use of herbal remedies or dietary supplements. The medical records were searched for evidence that the medical team had knowledge of the use of herbal remedies or dietary supplements. RESULTS: Two hundred and ninety-nine hospitalized medical patients were interviewed. Of the participants, 26.8% were herbal or dietary supplement consumers (HC). On multivariate analysis the only variates associated with herbal or dietary supplement consumption were the hospital [odds ratio (OR) 2.97, 95% confidence interval (CI) 1.29, 6.52], income (OR 0.39, 95% CI 0.15, 1.05), smoking habits (OR 0.17, 95% CI 0.05, 0.55) and benign prostatic hypertrophy (OR 4.64, 95% CI 1.3, 16.5). Ninety-four percent of the patients had not been asked specifically of herbal consumption by the medical team. Only 23% of the hospital's medical files of the HC patients had any record of the use of herbal or dietary supplements. Seven possible drug-herbal interactions were encountered (7.1%). The most serious was an interaction between camomile tea and ciclosporin. CONCLUSIONS: Herbal remedy consumption is common amongst patients hospitalized in internal medicine wards and is often overlooked by the medical team. Patients and doctors should be more aware of the possible adverse effects and of the potential of herb-drug interactions.     

Appendicular desmoid tumour, an uncommon cause for abdominal pain

This case report refers to a 17-year-old woman who was admitted to a gynaecological ward with severe lower abdominal pain. She underwent an explorative laparotomy, which revealed a large mass arising from the appendix. Her uterus, ovaries and tubes were found to be normal. Appendicectomy and omental biopsy was performed. Histology revealed a mesenteric fibromatosis–desmoid tumour.     

Contemporary results of open repair of ruptured descending thoracic and thoracoabdominal aortic aneurysms

OBJECTIVE: The purpose of this study was to evaluate the results of open repair for ruptured descending thoracic and thoracoabdominal aortic aneurysm (RDTAA). METHODS: A retrospective review identified 41 consecutive cases of open surgical repair in 40 patients presenting with nontraumatic, atherosclerotic RDTAA from 1996 to 2006. Patients with traumatic injuries or complicated dissections were excluded. Patient characteristics and preoperative, intraoperative, and postoperative variables were collected from the medical record. Univariate and logistic regression were used to identify factors contributing to mortality and morbidity in these patients. RESULTS: The operative mortality rate was 26.8% (11/41). All but two deaths occurred within 24 hours of operation; seven were intraoperative. Overall actuarial survival rates at 1 and 2 years were 53.7% and 47.1%, respectively. For those who survived to hospital discharge, the respective numbers were 73.3% and 64.4%. Intraoperative hypotension and blood transfusion requirements were independent predictors of perioperative death. Octogenarians had a mortality rate equivalent to that of the younger population (25% vs 27.6%; not significant). There was a strong trend toward an improved outcome in the latter part (2003-2006) compared with the first part (1995-2002; 13.6% vs 42.1%, respectively; P = .075). CONCLUSIONS: Direct open repair for RDTAA can be achieved with acceptable mortality and morbidity rates even in elderly patients. Improved outcome can be expected with increased volume and experience. This series should help establish a reference against which the results of endovascular endeavors and hybrid procedures could be compared.     

Severity and causality of maxillofacial trauma in the Southern region of Saudi Arabia

ObjectiveThe purpose of this study was to examine the causality and severity of maxillofacial trauma (MFT) among patients referred to a tertiary heath care center in the Southern Aseer region of Saudi Arabia.Materials and methodsThe charts of all MFT patients referred to the tertiary care center from September 2010 to November 2011 were retrospectively reviewed. Pertinent data, including patient age, gender, and cause of injury, were obtained from 101 selected charts.ResultsMale patients comprised 91% of the 101 selected cases. The highest percentage of MFT cases (88.7%) were caused by road traffic accidents (RTAs) while physical altercations and sports injuries accounted for approximately 6% and 2.8% of MFT cases, respectively. A high fracture: patient ratio of 2.4:1 was observed, which was likely due to vehicular speeding (high energy trauma) involved in RTAs in the mountain regions.ConclusionRTAs are a major cause of MFT in the southern region of Saudi. These accidents cause a heavy burden on the health care sector.     

Ten years experience with therapeutic apheresis in a community hospital

A retrospective study was carried out on 2,500 therapeutic hemapheresis procedures performed at a community teaching hospital from 1980 to 1990. Seventy-six percent of the procedures consisted of plasmapheresis (PE). The most frequently treated conditions were myasthenia gravis (MG), Guillain-Barré syndrome (GB), hyperviscosity (HV), and thrombotic thrombocytopenia purpura (TTP). Therapeutic results and clinical implications for these four conditions are discussed. © 1992 Wiley-Liss, Inc.     

Comparison of Remifentanil and Fentanyl in Patients Undergoing Craniotomy for Supratentorial Space-occupying Lesions

Background: Remifentanil hydrochloride is an ultra-short-acting, esterase-metabolized micro-opioid receptor agonist. This study compared the use of remifentanil or fentanyl during elective supratentorial craniotomy for space-occupying lesions.

Methods: Sixty-three adults gave written informed consent for this prospective, randomized, double-blind, multiple-center trial. Anesthesia was induced with thiopental, pancuronium, nitrous oxide/oxygen, and fentanyl (n = 32; 2 micro gram [center dot] kg [center dot] sup -1 min sup -1) or remifentanil (n = 31; 1 micro [center dot] kg sup -1 [center dot] min sup -1). After tracheal intubation, infusion rates were reduced to 0.03 micro gram [center dot] kg sup -1 [center dot] min sup -1 (fentanyl) or 0.2 micro gram [center dot] kg sup -1 [center dot] min sup -1 (remifentanil) and then adjusted to maintain anesthesia and stable hemodynamics. Isoflurane was given only after specified infusion rate increases had occurred. At the time of the first burr hole, intracranial pressure was measured in a subset of patients. At bone flap replacement either saline (fentanyl group) or remifentanil ([nearly equal] 0.2 micro gram [center dot] kg sup -1 [center dot] min sup -1) were infused until dressing completion. Hemodynamics and time to recovery were monitored for 60 min. Analgesic requirements and nausea and vomiting were observed for 24 h. Neurological examinations were performed before operation and on postoperative days 1 and 7.

Results: Induction hemodynamics were similar. Systolic blood pressure was greater in the patients receiving fentanyl after tracheal intubation (fentanyl = 127 +/- 18 mmHg; remifentanil = 113 +/- 18 mmHg; P = 0.004). Intracranial pressure (fentanyl = 14 +/- 13 mmHg; remifentanil = 13 +/- 10 mmHg) and cerebral perfusion pressure (fentanyl = 76 +/- 19 mmHg; remifentanil = 78 +/- 14 mmHg) were similar. Isoflurane use was greater in the patients who received fentanyl. Median time to tracheal extubation was similar (fentanyl = 4 min: range = -1 to 40 min; remifentanil = 5 min: range = 1 to 15 min). Seven patients receiving fentanyl and none receiving remifentanil required naloxone. Postoperative systolic blood pressure was greater (fentanyl = 134 +/- 16 mmHg; remifentanil = 147 +/- 15 mmHg; P = 0.001) and analgesics were required earlier in patients receiving remifentanil. Incidences of nausea and vomiting were similar.
