The aim of the present study is to determine the effect of blood lead on the health of industrial workers in United Arab Emirates (UAE). This is a cross-sectional pilot survey of blood lead levels (BLL) of 100 industrial workers (exposed) and 100 non-industrial workers (nonexposed), matched for age, sex and nationality selected from Al-Ain, Abu-Dhabi Emirate. Industrial workers had significantly higher mean of BLL (77.5+/-42.8 microg/dl and median 80.9 microg/dl) than non-industrial workers (19.8+/-12.3 microg/dl and median 11.0 microg/dl). In the present study, reported symptoms among industrial workers were strongly associated with BLL nausea/vomiting, muscular symptoms, dizziness, fatigue, irritability, memory disturbances, insomnia and allergic conjuctivitis, rhinitis and dermatitis. Furthermore, the present study revealed that industrial workers had higher prevalence of respiratory symptoms for phlegm, shortness of breath and diagnosed asthma. In conclusion, this study determined that occurrence of certain symptoms might be associated with lead exposure among industrial workers.

Clinical symptoms and self-reported health status in persons reporting multiple chemical sensitivities (MCS) are presented from a 9-year follow-up study. Eighteen (69%) subjects from a sample of 26 persons originally interviewed in 1988 were followed up in 1997 and given structured interviews and self-report questionnaires. In terms of psychiatric diagnosis, 15 (83%) met DSM-IV criteria for a lifetime mood disorder, 10 (56%) for a lifetime anxiety disorder, and 10 (56%) for a lifetime somatoform disorder. Seven (39%) of subjects met criteria for a personality disorder using the Personality Diagnostic Questionnaire-IV. Self-report data from the Illness Behavior Questionnaire and Symptom Checklist-90-Revised show little change from 1988. The 10 most frequent complaints attributed to MCS were headache, memory loss, forgetfulness, sore throat, joint aches, trouble thinking, shortness of breath, back pain, muscle aches, and nausea. Global assessment showed that 2 (11%) had "remitted", 8 (45%) were "much" or "very much" improved, 6 (33%) were "improved", and 2 (11%) were "unchanged/worse". Mean scores on the SF-36 health survey showed that, compared to U.S. population means, subjects reported worse physical functioning, more bodily pain, worse general health, worse social functioning, and more emotional-role impairment; self-reported mental health was better than the U.S. population mean. All subjects maintained a belief that they had MCS; 16 (89%) acknowledged that the diagnosis was controversial. It is concluded that the subjects remain strongly committed to their diagnosis of MCS. Most have improved since their original interview, but many remain symptomatic and continue to report ongoing lifestyle changes.

A 36 year old Turkish female patient complaining of widespread redness of the skin, shortness of breath, palpitations, nausea, hum and reverberation in the head was examined. The patient was diagnosed with catecholamine induced hypertension, which was caused by paraganglionoma. In addition, left ventricular concentric hypertrophy accompanied by systolic gradient in mid-ventricle, which is rarely observed, was determined by echocardiography. Hypertensive attacks and mid-ventricular systolic gradient disappeared after surgery. This case shows that one of the causes of the heart failure due to catecholamine releasing tumors can be left ventricular obstruction.

A request for euthanasia (RFE) in the terminally ill raises concerns that physical and/or mental suffering remain unaddressed and thus mandates a critical appraisal of the physical and psychosocial aspects of the individual concerned. An alert datasheet (AD) is completed at the weekly Palliative Care Service (PCS) meeting as a measure of self-audit and deals with issues considered to be of importance in ensuring high-quality patient care, one of which is a RFE. The ADs for the year 2000 were examined, and where a RFE was made, the contributing factors as documented on the forms together with demographic data, the case synopsis and patient-rated main three problems/issues were appraised. Among 490 patients referred to the service, there were 6 RFE (1.6%) recorded. These were made by 1 female (age 44) and 5 male (age range 58-78 years) patients. Four of these patients had a cancer diagnosis (all had metastatic disease). Median survival from first contact with the PCS was 13 days (range 4-29). The contributing factors identified were: uncontrolled symptoms (2/6 - severe constipation in both), depression (1/6), issues of burden/dependency (6/6), lack of autonomy/control (4/6), sense of hopelessness (3/6) and social isolation (4/6). The patient-rated main three problems were: (i) physical symptoms (5/6), specifically pain (2/6), shortness of breath (2/6), fatigue (1/6) and nausea (1/6), and (ii) psychosocial issues (4/6). A RFE was seen to be a multifactorial entity (issues of burden/dependency being universal) and merits a focused appraisal in order to adequately address potentially unrecognised issues that contribute to suffering. The short median survival from the time of referral to the service suggests that (i) RFEs are made late in the trajectory of the illness and (ii) these patients are being referred late in the course of their illness - thus limiting the window in which these issues can be addressed.

Chest pain is a typical feature of obstructive coronary disease, but unless carefully evaluated, may not be a reliable predictor in women. The use of standardized questionnaires and evaluation tools has been developed and validated in men, but only partially in women. If women over the age of 65 are evaluated, typical features of angina are much more reliable in representing coronary disease than in younger women, who may have risk factors, but are less likely to have significant coronary disease. Many studies have shown that chest pain is the most common presenting symptom for both men and women with unstable coronary syndromes or myocardial infarction. Other associated features, such as nausea, shortness of breath, and back pain, may be more common in women, while diaphoresis is more common in men. Since men and women at risk for coronary disease should be evaluated when any potential symptoms emerge, it is useful to employ a standardized assessment of the characteristics of the symptoms as well as a uniform approach to further evaluation.

Will to live has been shown to vary considerably during the final course of a terminal illness. The goal of this study was to identify illness-related and demographic variables predicting will to live among dying patients. Subjects were 168 patients with cancer who were admitted for palliative care. Will to live was measured twice daily for the duration of hospitalization by using a self-report 100-mm visual analogue scale. Will-to-live data for each patient were summarized into two statistics, intercept and slope, by using simple linear regression analyses. Intercept-slope pairs for all patients were classified into the following five clusters by using spatial and conceptual criteria: patients with sustained high will to live (58%), patients with sustained moderate will to live (11%), patients with sustained low will to live (3%), will-to-live relinquishers (18%), and will-to-live acquirers (10%). Discriminant analyses revealed seven variables that accounted for 69% of the variance in cluster membership: anxiety, shortness of breath, nausea, length of survival from time of admission, having a diagnosis of colon cancer, having no religion, and living with a spouse.

Dihydroetorphine (DHE) is one of the strongest analgesic opioid alkaloids known; it is 1000 to 12000 times more potent than morphine. Several in vitro and in vivo studies have shown that DHE is a selective mu-opioid receptor (OP(3)) agonist that also binds and activates all human recombinant mu-, delta-, and kappa-opioid receptors (OP(3), OP(1), and OP(2)). The onset of the analgesic effect of DHE in rodents is rapid, 5 to 15 min after parenteral administration; the duration of action is short, the analgesic effect disappears within 120 min after administration. By oral administration much higher doses of DHE are required to produce analgesic effects. These characteristics are accounted for by the pharmacokinetic properties of DHE in the rat, namely, by rapid distribution of DHE from the injection site to the brain and rapid metabolism by glucuronidation in the gut and liver followed by elimination into the bile. Continuous infusion and repeated administration of DHE lead to the development of tolerance to analgesia, physical dependence, and a rewarding effect in normal rats but not in animals with formalin-induced inflammation. Although formalin-induced inflammation is only one type of pain stimulus, these findings suggest that DHE addiction would be observed only in the case of pain-free conditions. Clinical reports in China show that sublingual doses of DHE, 20 to 180 microg, produce a potent analgesic effect with only mild side effects, including dizziness, somnolence, nausea, vomiting, constipation, and shortness of breath. To improve the short-lasting effect following sublingual administration, transdermal delivery of DHE via a patch has been investigated. The patch formulation of DHE produces continuous analgesic effect with minimal physical dependence and rewarding effect in rats suffering from chronic pain. This patch formulation, which is very suitable for DHE, may be viable for the treatment of severe pain and is likely to improve patients' quality of life.

Congenital diaphragmatic hernia (CDH) is rare in adults. We report a 24 year old woman presenting with shortness of breath, chest pain and nausea after the birth of her first baby. Clinical examination, plain radiography and a CT scan revealed herniation of abdominal contents into her left chest. Via a midline laparotomy, the contents were reduced and the defect repaired, using a mesh. She remains symptom-free three years since her surgery and even after a second childbirth. A brief review of the literature reporting adult diaphragmatic hernia of congenital origin accompanies this case report. We conclude that symptomatic CDH in adults usually presents as an emergency with gastrointestinal and occasionally respiratory complications. Early diagnosis and repair is essential to avoid subsequent morbidity and mortality.

Although efforts have been made to define optimal terminal care in palliative care units (PCUs), comprehensive longitudinal evaluations of care outcomes in PCUs at the end of life are scarce. In this study, changes in functional status (assistance needed for walking, and toilet use) and symptoms (pain, nausea, shortness of breath, depression, and anxiety) were assessed in all patients (n=355) admitted to 10 PCUs in Dutch nursing homes. Outcomes were measured at 24 hours, 48 hours, one week, and two weeks before death, and at PCU admission. Results show that functional status deteriorated from admission to one week before death, but most symptoms did not worsen in the last three weeks before death. Decreases in pain, anxiety, and nausea were observed. The results suggest that the care provided in the PCUs stabilized the symptom levels. Patients who die between two and four weeks appeared to have more favorable symptom change patterns than patients who die within two weeks, which supports the recommendation to admit eligible patients in earlier phases of their disease. Limitations include the use of proxy measures and some forms of selection bias, which may lead to underestimation of symptom levels.

Lactic acidosis is an uncommon but potentially life-threatening adverse effect of didanosine. When given concomitantly with tenofovir disoproxil fumarate (DF), the area under the concentration-time curve of didanosine is increased by 48-60%. A 63-year-old man with human immunodeficiency virus (HIV) infection tolerated several didanosine-containing antiretroviral regimens. He developed generalized weakness, loss of appetite, weight loss, nausea, and vomiting 1.5 years after tenofovir DF was added to his didanosine-containing regimen. He was diagnosed with lactic acidosis and died after a 13-day hospital stay, when his lactate level increased to 189.7 mg/dl and his arterial blood gas pH value fell to 6.75. Health care providers should maintain a high index of suspicion for lactic acidosis in patients with HIV infection who receive didanosine and tenofovir DF concurrently. For patients receiving antiretroviral regimens containing this drug combination, it would be prudent to monitor lactate levels periodically. This is especially important when patients experience symptoms suggestive of lactic acidosis, such as weakness, abdominal pain, weight loss, nausea and vomiting, and shortness of breath.
