This study determines the prevalence of types of sicknesses and diseases affecting patients visiting health service facilities and the available health services within the Selebi Phikwe Ni-Cu mine area, Botswana. Through the administration of questionnaires and structured questions, attempts were made to establish and verify the existing human health problems at the study area by focusing on respiratory tract related symptoms of sicknesses and diseases. With the aid of statistical package for social sciences (SPSS), interpreted results from respondents indicated that all the health service providers served patients suffering from headaches, persistent coughing, chest pains, lower abdominal pains, pain when passing out urine, genital discharge and diarrhea. Seventy one percent of the health service providers indicated that their patients suffered from body weakness, 86 % indicated that they had patients who suffered from recent loss of body weight, and another 86 % pointed out that their patients had influenza/common cold. Other health complaints reported included unusual spitting, shortness of breath, palpitations, nausea/vomiting, diarrhoea, and constipation. Moreover the health service providers indicated that they had patients who suffered from significant illnesses of which some passed away. However if there are lacking facilities, patients are referred to bigger health service providers in the country. The findings of the study do not in general depict demarcating differences of health status of residents of the study area to those of the control site. A need therefore for further investigations to be conducted to establish relations of mining activities to human health at Selebi Phikwe is called for.

Women in labour receiving epidural analgesia with 15 ml bupivacaine 0.1% and 2 microg.ml(-1) fentanyl followed by 10-15-ml top-ups as required, who needed Caesarean section, were randomly allocated to receive 20 ml levobupivacaine 0.5% over 3 min with either 75 microg fentanyl (1.5 ml) or 1.5 ml saline. Further top-ups or inhaled or intravenous supplementation were given for breakthrough pain. Time to onset (loss of cold sensation to T4 and touch sensation to T5 bilaterally), quality of analgesia and side-effects were recorded. The study was stopped after 112 patients had been randomly assigned, due to a unit protocol change, from midwife-administered top-ups to patient-controlled epidural analgesia. Data from 51 patients given fentanyl and 54 given saline were available for analysis. There were no significant differences in onset times or supplementation between the groups, but there was more intra-operative nausea/vomiting with fentanyl (53%) than with saline (18%; p = 0.004). We found no advantage of adding fentanyl to epidural levobupivacaine when extending epidural analgesia in women already receiving epidural fentanyl during labour and there was an increased incidence of intra-operative nausea and vomiting. Power analysis suggested the same conclusion even had the study proceeded to completion.

We describe the occurrence of vasovagal reaction in two patients who underwent CT colonography (CTC). The patients, asymptomatic, were submitted to CTC in one case after right colectomy and in one case for screening purposes. The vasovagal symptoms occurred after pneumocolon and acquisition in the prone decubitus, and included headache, hypotension, bradycardia, cold sweat and pallor, nausea, and diaphoresis. Abdominal pain was also referred. All symptoms resolved within 30 min to 3 h from their onset. In all cases the vasovagal reaction occurred after prone decubitus. CTC images showed a significant distension of the small bowel. Vasovagal reactions are potential complications of CTC.

Nausea and vomiting are important as biological systems for drug side effects, disease co-morbidities, and defenses against food poisoning. Vomiting can serve the function of emptying a noxious chemical from the gut, and nausea appears to play a role in a conditioned response to avoid ingestion of offending substances. The sensory pathways for nausea and vomiting, such as gut and vestibular inputs, are generally defined but the problem of determining the brain's final common pathway and central pattern generator for nausea and vomiting is largely unsolved. A neurophysiological analysis of brain pathways provides an opportunity to more closely determine the neurobiology of nausea and vomiting and its prodromal signs (e.g., cold sweating, salivation).

The analgesic drug tramadol is bioactivated by CYP2D6 to the opioid receptor agonist O-desmethyltramadol. Case reports indicated that carriers of the CYP2D6 gene duplication may be at high risk for opioid adverse events. However, the effects of the CYP2D6 duplication on kinetics and dynamics of tramadol have not been systematically studied. Pharmacokinetics and effects were monitored after a single dose of 100 mg racemic tramadol in 11 carriers of a CYP2D6 gene duplication allele (ultrarapid metabolizer [UM]) and compared with 11 carriers of 2 active CYP2D6 genes (extensive metabolizer [EM]). Pharmacodynamics was measured by cold pressure test, pupillometry, and standardized adverse event recording. The maximum plasma concentrations of the active metabolite (+)R,R-O-desmethyltramadol were significantly higher in the UM group compared with the EM group (P = 0.005; t test) with a mean difference of 14 ng/mL (95% confidence limit of difference, 2-26 ng/mL). Median (+)R,R-tramadol area under the curve was 786 and 587 mug.h.L in EMs and UMs, and the corresponding median (+)R,R-O-desmethyltramadol area under the curve was 416 and 448 mug.h.L (P = 0.005, t test). There was an increased pain threshold and pain tolerance and a stronger miosis after tramadol in UMs compared with EMs. Almost 50% of the UM group experienced nausea compared with only 9% of the EM group. In conclusion, pharmacokinetic differences between EMs and UMs were smaller than expected; nevertheless, UMs were more sensitive to tramadol than EMs. Therefore, tramadol may frequently cause adverse effects in southern European and Northern African populations with a high proportion of UMs.

Aim of this study was to compare post-operative recovery over 14 days in children submitted to tonsillectomy using a bipolar radiofrequency-based plasma device (Coblation, Evac 70, ArthroCare Corp, Sunnyvale, CA, USA) to cold dissection. Paediatric patients (n = 42) aged 5-16 years old with chronic tonsillitis underwent tonsillectomy using cold dissection with suture ligatures or a plasma device (Evac 70, ArthroCare Corp, Sunnyvale, CA, USA). Pain intensity on the first day, use of analgesics, type of diet, and days of pain, fever, nausea, and absence from school were determined. Groups were compared using time-to-event (Kaplan-Meier) curves and statistically evaluated using the Breslow (generalized Wilcoxon) test. Children undergoing plasma tonsillectomy reported significantly less pain on the first post-operative day (1.2 +/- 0.9 vs. 3.5 +/- 1.5, p < 0.001), fewer days of pain (4.8 +/- 1.5 vs. 9.4 +/- 1.2, p <0.001), pain medication withdrawal (2.6 +/- 1.3 vs. 4.5 +/- 1.3, p <0.001) and earlier use of liquid diet (5.1 +/- 1.4 vs. 8.5 +/- 2.1, p <0.001), and fewer school days lost (5.3 +/- 1.7 vs. 8.9 +/- 1.5, p <0.001). After completing this study, plasma tonsillectomy was adopted for the majority of cases. Benefits of the plasma device include the possibility both to excise tissue and coagulate bleeding vessels using the same device whilst improving quality of post-operative recovery over cold dissection with suture ligatures.

Clinical lateralizing signs are the phenomena which can unequivocally refer to the hemispheric onset of epileptic seizures. They can improve the localization of epileptogenic zone during presurgical evaluation, moreover, their presence can predict a success of surgical treatment. Primary sensory phenomena such as visual aura in one half of the field of vision or unilateral ictal somatosensory sensation always appear on the contralateral to the focus. Periictal unilateral headache, although it is an infrequent symptom, is usually an ipsilateral sign. Primary motor phenomena like epileptic clonic, tonic movements, the version of head ubiquitously appear contralateral to the epileptogenic zone. Very useful lateralization sign is the ictal hand-dystonia which lateralizes to the contralateral hemisphere in nearly 100%. The last clonus of the secondarily generalized tonic-clonic seizure lateralizes to the ipsilateral hemisphere in 85%. The fast component of ictal nystagmus appears in nearly 100% on the contralateral side of the epileptic focus. Vegetative symptoms during seizures arising from temporal lobe such as spitting, nausea, vomiting, urinary urge are typical for seizures originating from non-dominant (right) hemisphere. Ictal pallor and cold shivers are dominant hemispheric lateralization signs. Postictal unilateral nose wiping refers to the ipsilateral hemispheric focus compared to the wiping hand. Ictal or postictal aphasia refers to seizure arising from dominant hemisphere. Intelligable speech during complex partial seizures appears in non-dominant seizures. Automatism with preserved consciousness refers to the seizures of non-dominant temporal lobe.

This study was conducted to examine the feelings, symptom management, and needs of patients with gynecological cancer receiving chemotherapy at Chiang Mai University Hospital, Chiang Mai, Thailand. During the period July 2006 and June 2007, 286 patients were recruited. The most common chemotherapeutic regimen was paclitaxel and carboplatin followed by single carboplatin and weekly cisplatin. Five severe and frequent complications were as follows: alopecia, anorexia, fatigue, nausea, and vomiting. Some 41.9% could well tolerate with such complications but 50.3% had various feelings including irritability, boredom, dejection, fear, stress, and anxiety. Anorexia was the symptom that the majority of them could best manage, 17.4% by eating as much as they can and 32.6% by selecting different foods from normal, such as fruit, sweetmeats, noodles, milk. For nausea and vomiting, 31.3% managed by eating fruit, drinking sour juice, and holding sour fruit in mouth, and 16.0% used the breathing method, eating something cold, such as ice-cream, or hot food like noodles. For health needs, 41.0% needed encouragement, care, health education, and information from doctors and nurses, and 5.0% needed care and encouragement from their family, and sympathy from neighbors and colleagues. In conclusion, gynecological cancer patients receiving chemotherapy experience a variety of feelings, symptom management. and health needs. Nurses need to explain the pathology of the occurring symptoms so that the patients can understand and accept the symptoms to lessen their negative impact.

A patient was presented with four days of vomiting, abdominal pain and sweating. At presentation the Capillary Blood Glucose (CBG) was 1.7 mmol/L, the Blood Pressure (BP) was 182/102 mmHg, and the pulse 100 bpm. On examination, he was sweaty, pale and cold. The initial differential diagnosis was hypoglycaemia secondary to insulin abuse, hypoadrenalism or insulinoma, the transient hypertension being considered a consequence of sympathetic stimulation. He remained clinically well overnight with a CBG of 10-14 mmol/L following intravenous glucose. The next morning he complained of nausea and abdominal pain. The BP had risen to 203/127 mmHg when he was later reviewed, having been given 10mg intramuscular metoclopramide. Shortly afterwards, he developed acute pulmonary oedema and had become hypoglycaemic again; a phaeochromocytoma crisis was suspected. Treatment with alpha-adrenoceptor blockade with intravenous phenoxybenzamine was advised. However, the patient deteriorated and died in the Intensive Care Unit within two hours. Autopsy examination confirmed a phaeochromocytoma in the left adrenal, with haemorrhage within the head of pancreas, but no evidence of a pancreatic tumour.

Ciguatera fish poisoning (CFP) is a distinctive type of foodborne disease that results from eating predatory ocean fish contaminated with ciguatoxins. As many as 50,000 cases are reported worldwide annually, and the condition is endemic in tropical and subtropical regions of the Pacific basin, Indian Ocean, and Caribbean. In the United States, 5--70 cases per 10,000 persons are estimated to occur yearly in ciguatera-endemic states and territories. CFP can cause gastrointestinal symptoms (nausea, vomiting, abdominal cramps, or diarrhea) within a few hours of eating contaminated fish. Neurologic symptoms, with or without gastrointestinal disturbance, can include fatigue, muscle pain, itching, tingling, and (most characteristically) reversal of hot and cold sensation. This report describes a cluster of nine cases of CFP that occurred in North Carolina in June 2007. Among the nine patients, six experienced reversal of hot and cold sensations, five had neurologic symptoms only, and overall symptoms persisted for more than 6 months in three patients. Among seven patients who were sexually active, six patients also complained of painful intercourse. This report highlights the potential risks of eating contaminated ocean fish. Local and state health departments can train emergency and urgent care physicians in the recognition of CFP and make them aware that symptoms can persist for months to years.
