RESUMEN
INTRODUCTION: Disaster epidemiological studies indicate that Asia has the highest frequency of natural disasters. Rural communities are heavily impacted by natural disasters and have different healthcare needs to urban ones. Referencing Asian countries, this paper's objective is to provide an overview of health impacts and the current evidence for designing programmes and policies related to rural health emergency and disaster risk management (health-EDRM). SOURCES OF DATA: This paper uses published English-only reports and papers retrieved from PubMed, Google Scholar, Embase, Medline and PsycINFO on rural disaster and emergency responses and relief, health impact and disease patterns in Asia (January 2000-January 2018). AREAS OF AGREEMENT: Earthquakes are the most studied natural disasters in rural communities. The medical burden and health needs of rural communities were most commonly reported among populations of extreme age. Most of the existing research evidence for rural interventions was reported in China. There lacks published peer-reviewed reports of programme impacts on personal and community preparedness. AREAS OF CONTROVERSY: There is a lack of evidence-based health-EDRM interventions to evaluate implementation effectiveness in rural areas despite vast volumes of health-related disaster literature. GROWING POINTS: Climate change-related disasters are increasing in frequency and severity. Evidence is needed for disaster risk reduction interventions to address the health risks specific to rural populations. AREAS TIMELY FOR DEVELOPING RESEARCH: To support global policy development, urgent evidence is needed on the intervention effectiveness, long-term health outcomes, local and cultural relevance as well as sustainability of health relief produced by Health-EDRM programmes in rural areas.

INTRODUCTION: Mushroom poisoning is a cause of major mortality and morbidity all over the world. Although Hong Kong people consume a lot of mushrooms, there are only a few clinical studies and reviews of local mushroom poisoning. This study aimed to review the clinical characteristics, source, and outcome of mushroom poisoning incidences in Hong Kong. METHODS: This descriptive case series review was conducted by the Hong Kong Poison Information Centre and involved all cases of mushroom poisoning reported to the Centre from 1 July 2005 to 30 June 2015. RESULTS: Overall, 67 cases of mushroom poisoning were reported. Of these, 60 (90%) cases presented with gastrointestinal symptoms of vomiting, diarrhoea, and abdominal pain. Gastrointestinal symptoms were early onset (<6 hours post-ingestion) and not severe in 53 patients and all recovered after symptomatic treatment and a short duration of hospital care. Gastrointestinal symptoms, however, were of late onset (≥6 hours post-ingestion) in seven patients; these were life-threatening cases of amatoxin poisoning. In all cases, the poisonous mushroom had been picked from the wild. Three cases were imported from other countries, and four collected and consumed the amatoxin-containing mushrooms in Hong Kong. Of the seven cases of amatoxin poisoning, six were critically ill, of whom one died and two required liver transplantation. There was one confirmed case of hallucinogenic mushroom poisoning caused by Tylopilus nigerrimus after consumption of a commercial mushroom product. A number of poisoning incidences involved the consumption of wild-harvested dried porcini purchased in the market. CONCLUSION: Most cases of mushroom poisoning in Hong Kong presented with gastrointestinal symptoms and followed a benign course. Life-threatening cases of amatoxin poisoning are occasionally seen. Doctors should consider this diagnosis in patients who present with gastrointestinal symptoms that begin 6 hours or more after mushroom consumption.

BACKGROUNDS: Diabetes mellitus (DM) is a common endocrine disorder and an increasing epidemic worldwide. Proportional diabetic patients eventually develop cutaneous diseases. OBJECTIVES: This study determined the statistical association of cutaneous manifestations and DM as well as the DM-associated cutaneous manifestations in elderly male residents. METHODS: A cross-sectional study was conducted in a Veterans Home in Taiwan. The cutaneous manifestations and major systemic diseases of the residents were recorded separately. Univariate logistic regression and multivariate analysis after adjustment for age, body mass index and significant major systemic diseases provided odds ratios and P values for the statistical association. RESULTS: A total of 313 male residents (age ≥65 years) were recruited, including 70 (22.4%) with DM. Their most common cutaneous manifestations included fungal infection (77%) and brown spots on the legs (38.3%). Chronic ulcers adjusted odds ratios (AOR 4.90, 95%CI: 1.82-13.19; P = 0.002), brown spots on the legs (AOR 6.82, 95%CI: 3.60-12.89; P < 0.001) and pruritus (AOR 12.86, 95%CI: 4.40-37.59; P < 0.001) were significantly associated with DM. The diabetic residents were inclined to have chronic ulcers, brown spots on the legs and pruritus at a 7.46-fold higher risk (AOR 7.46, 95%CI: 3.86-14.43; P < 0.001). The diabetic residents exhibited marginally higher risks of bacterial infection, scabies, or skin tags. CONCLUSION: The DM-associated cutaneous manifestations were chronic ulcers, brown spots on the legs, and pruritus. By observing clues of diabetic cutaneous features, a more complete condition of diabetic patients can be appreciated. The information is essential for providing appropriate treatment and key nursing points regarding the diabetes-associated skin diseases.

PURPOSE: To investigate the role of the Prostate Health Index (phi) in prostate cancer (PCa) detection in patients with a prostate-specific antigen (PSA) level of 4-10 ng/mL receiving their first prostatic biopsy in an Asian population. METHODS: This was a retrospective study of archived serum samples from patients enlisted in our tissue bank. Patients over 50 years old, with PSA level of 4-10 ng/mL, a negative digital rectal examination, and received their first prostatic biopsy between April 2008 and April 2013, were recruited. The serum sample collected before biopsy was retrieved for the measurement of various PSA derivatives and the phi value was calculated for each patient. The performance of these parameters in predicting the prostatic biopsy results was assessed. RESULTS: Two hundred and thirty consecutive patients, with 21 (9.13 %) diagnosed with PCa, were recruited for this study. Statistically significant differences between PCa patients and non-PCa patients were found for total PSA, PSA density, [-2]proPSA (p2PSA), free-to-total PSA ratio (%fPSA), p2PSA-to-free PSA ratio (%p2PSA), and phi. The areas under the curve of the receiver operating characteristic curve for total PSA, PSA density, %fPSA, %p2PSA, and phi were 0.547, 0.634, 0.654, 0.768, and 0.781, respectively. The phi was the best predictor of the prostatic biopsies results. At a sensitivity of 90 %, the use of the phi could have avoided unnecessary biopsies in 104 (45.2 %) patients. CONCLUSIONS: Use of the phi could improve the accuracy of PCa detection in patients with an elevated PSA level and thus avoid unnecessary prostatic biopsies.

BACKGROUND: Recent researches show that psoriasis is frequently associated with systemic co-morbidities. OBJECTIVES: This study aimed to identify possible associated co-morbidities in psoriatic patients stratified by age and sex. METHODS: In this retrospective hospital-based case-control study, patients diagnosed as psoriasis at the Kaohsiung Veterans General Hospital in Taiwan between January 2008 and December 2009 were enrolled as cases and classified into severe and mild based on their use of systemic therapy. The controls were the patients without psoriasis matched the cases in 1 : 1 ratio with same birth year, sex and calendar date. Odds ratios (ORs) and 95% confidence intervals (CIs) from the conditional logistic regression method were used to assess the risk of co-morbidities between psoriatic and non-psoriatic patients. RESULTS: A total of 447 cases and 447 matched controls, with mean age of 51.3 ± 18.3 years and male-to-female ratio of 2.17 : 1 were enrolled. The ratio of mild-to-severe was 3.5 : 1. Compared with non-psoriatic patients, psoriatic patients had significantly higher OR of hypertension (1.85), diabetes mellitus (2.88) and obesity (1.66). Among those aged ≥51 years old, there was significant risk in male psoriatic patients with ischaemic and hypertensive heart disease (IHHD) (OR = 2.167) after eliminating female IHHD psoriatic patients (OR = 0.125). Psoriasis was significantly negatively associated with cancers (OR = 0.267). Psoriasis patients often had the usual drinking habit (OR = 2.23) and seldom had an occasional drinking habit (OR = 0.25). CONCLUSIONS: Psoriasis is strongly associated with hypertension, diabetes mellitus and obesity. The association between psoriasis and IHHD, stroke, cancers, smoking and alcohol habits warrant more investigation.

BACKGROUND: To examine the association of microalbuminuria (MAU) with the carotid intima-media thickness (CIMT) in Chinese Type 2 diabetic subjects. MATERIALS AND METHODS: Two hundred and thirty-nine patients (64±13 yr, 154 males) were divided into 2 groups: one with MAU (no.=119) or one without (no.=120). We recorded clinical and biochemical data as well as CIMT and ankle-brachial index (ABI). RESULTS: The patients with MAU had had diabetes mellitus (DM) longer, had higher blood pressure (BP). They also had lower estimated glomerular filtration rate (eGFR) and higher levels of circulating glucose, glycated hemoglobin, high sensitivity C-reactive protein than those without. Lower mean ABI was found in those with MAU, however, they did not have higher mean CIMT (0.72±0.15 vs 0.71±0.16 mm, p=0.525). In patients without MAU, CIMT correlated with age, DM duration, systolic BP, eGFR, albumin- to-creatinine ratio, and ABI. However, in those with MAU, CIMT correlated only with age and eGFR. Multivariate regression analysis revealed that mean CIMT correlated only with age for patients without MAU, but correlated with age and body mass index for those with MAU. Dividing the patients into 5 age groups, we found that the older the patient, the higher the mean CIMT with no group differences between those with and without MAU in both genders. However, patients with eGFR below 60 ml/min/1.73 m(2) had higher mean CIMT than those above (0.75±0.16 vs 0.69±0.14 mm, p=0.005). CONCLUSIONS: Type 2 diabetic patients with MAU were not associated with higher CIMT. Conversely, those with deterioration of renal function were more likely associated.

Possible masking of tuberculosis (TB) in treatment of community-acquired respiratory infection by newer fluoroquinolones has not been examined in randomised controlled trials. We undertook a randomised, open-label controlled trial involving adults with community-acquired pneumonia or infective exacerbation of bronchiectasis encountered in government chest clinics in Hong Kong. 427 participants were assigned by random permutated blocks of 20 to receive either amoxicillin clavulanate (n = 212) or moxifloxacin (n = 215). Participants were followed for 1 yr for active pulmonary TB. Excluding three participants with positive baseline culture, 13 developed active pulmonary TB: 10 (4.8%) out of 210 were given amoxicillin clavulanate, and three (1.4%) out of 214 were given moxifloxacin. The difference was significant by both proportion and time-to-event analysis. Post hoc analysis showed a significant decrease in the proportion with active pulmonary TB from 4.8% to 2.4% and 0% among participants given amoxicillin clavulanate (n = 210), moxifloxacin for predominantly 5 days (n = 127) and 10 days (n = 87), respectively. The log rank test for trend also showed a significant difference between the three subgroups. Regression models reaffirmed the linear effect; the adjusted odds ratio (95% confidence interval) of active pulmonary TB after moxifloxacin exposure up to predominantly 10 days was 0.3 (0.1-0.9). Newer fluoroquinolones appear to mask active pulmonary TB.

BACKGROUND: In addition to lipid lowering, further pleotropic effects of statins have been postulated. We aimed to study if the various pleotropic effects are due indirectly to the modulation of adipocytokines. MATERIALS AND METHODS: We studied the effect of atorvastatin on insulin sensitivity and the plasma adiponectin and leptin concentrations. Our randomized open labeled study had 29 hyperlipidemic Type 2 diabetic patients (14 females, 15 males, mean age 60.0+/-2.2 yr). They were randomized into three 12-week atorvastatin intervention types. Each day patients were given either 10 mg (no.=10), 20 mg (no.=10) or 40 mg (no.=9). Evaluations were performed before and after intervention. RESULTS: All baseline characteristics were statistically identical in the 3 groups. Drop in total cholesterol, LDL-cholesterol, and triglyceride levels were measured at the end. With 10 mg the drop was 30%, 37%, and 30%. The 20 mg group was 43%, 54%, and 34%. The 40 mg group was 42%, 51%, and 27%. Groups had no significant change of body mass index, HDLcholesterol, and glycated hemoglobin levels. Also, levels of insulin, adiponectin, leptin, homeostasis model assessment index (HOMA) and Quantitative Insulin Sensitivity Check Index (QUICKI) stayed the same. Pooled parameters of all 29 patients showed no difference in levels of insulin, adiponectin, leptin, HOMA, and QUICKI before and after treatment. CONCLUSIONS: Atorvstatin does not affect insulin sensitivity and the adiponectin or leptin levels in hyperlipidemic Type 2 diabetes.

OBJECTIVE: To evaluate the outcome and the change in quality of life of patients with chronic rhinitis after treatment with desloratadine. STUDY DESIGN: A prospective, open-label, non-blinded, non-randomised study of patients in a secondary and tertiary ENT referral centre. METHODS: Chinese patients with chronic rhinitis were recruited. The patients were assessed by a questionnaire that included rhinitis symptoms score and SF-36 health survey components. Endoscopic assessment was performed with a rigid nasoendoscope and scored according to the modified endoscopic appearance score of Lund and Kennedy. A 12-week course of desloratadine 5 mg daily was prescribed. Patients were re-evaluated after treatment. A total of 47 subjects completed the study. RESULTS: There were significant reductions in median rhinitis symptoms score, from six to five (p < 0.001), and in median endoscopic appearance score, from five to three (p < 0.001). Patients' general health perception was also improved after treatment (p == 0.022). CONCLUSION: Desloratadine may be an effective treatment which provides symptomatic relief and improves the quality of life in patients with chronic rhinitis.

OBJECTIVE: To evaluate the clinical presentation and management of internal carotid artery rupture after irradiation and osteoradionecrosis of the skull base. STUDY DESIGN AND SETTING: A retrospective review of the patients in an otorhinolaryngology-head and neck secondary and tertiary referral center. METHODOLOGY: From January 1993 to December 1996, patients with hemorrhage from internal carotid artery as a complication of irradiation and osteoradionecrosis of skull base were reviewed and analyzed. RESULTS: Four patients with internal carotid arterial rupture were included in this study. Angiography was performed in all cases. Embolization of the aneurysm was performed on 2 patients and the remaining 2 patients underwent occlusion of their internal carotid arteries. Three of the 4 patients did not survive. The fourth is currently alive and well 18 months after embolization of 1 internal carotid artery. CONCLUSION: Skull base osteoradionecrosis with bleeding from internal carotid artery is a potentially fatal complication of irradiation. Angiography was the mainstay of diagnosis with embolization of the aneurysm and embolization or ligation of the internal carotid artery being the management options. Internal carotid artery occlusion is the definitive treatment provided cross circulation is adequate. SIGNIFICANCE: The advantages and disadvantages of the treatment options are discussed and a management protocol is proposed.

BACKGROUND: To delineate the prognostic factors of patients suffering from hyperglycemic hyperosmolar nonketotic state (HHNK) in Taiwan. METHODS: We reviewed the charts of patients who had been admitted to the Division of Endocrinology and Metabolism of Kaohsiung Veterans General Hospital from 1992 to 1998 due to HHNK. General and clinical data were collected. The influential factors for prognosis were determined. RESULTS: One hundred and nineteen patients fulfilling the criteria of HHNK were included in our study. The mean age was 67.8 +/- 11.7 years with male predominance. Twenty-nine patients died which produced a fatality rate of 24.4%. Eighty-six (72.3%) cases occurred in patients with known diabetic history, while another thirty-three (27.7%) occurred in patients with no diabetic history. Most patients received oral antidiabetic drugs before HHNK episodes. The patients who died had shorter length of inpatient stay than did survivors. The leading precipitating factor was infection (57.1%), followed by poor compliance of medication (21.0%) and undiagnosed diabetes (10.9%). Fifty patients (42%) had a history of stroke. The risk factors for death included precipitation of HHNK by infection and low Glasgow coma scale (GCS) on admission. Old age itself did not contribute to death. Severity of hyperglycemia or hyperosmolarity was also not an important prognostic factor. Multiple logistic regression revealed that low GCS on admission was the most influential factor of leading to death. Most of the patients who died did so due to underlying precipitating factors. CONCLUSIONS: Neither age nor osmolarity, but underlying precipitating factors and state of consciousness were the most influential factors affecting the prognosis of HHNK.

Endothelin-1 (ET-1), a 21 amino acid peptide originally purified from conditioned medium of cultures of porcine aortic endothelial cells, is recognized as a product of many other cells as well. It is now known that there are three endothelin genes in the human genome (ET-1, ET-2, and ET-3). ET-1 and ET-2 are both strong vasoconstrictors, whereas ET-3 is a potentially weaker vasoconstrictor than the other two isoforms. Besides being the most potent vasoconstrictor yet known, ET-1 also acts as a mitogen on the vascular smooth muscle, and, thus, it may play a role in the development of vascular diseases. It is well known that accelerated angiopathy is a major complication in diabetes mellitus. As generalized endothelial cell damage is thought to occur in diabetic patients, ET-1, being released from the damaged endothelial cells, is able to make contact with the underlying vascular smooth muscle cells and thus could be one important cause of diabetic angiopathy. This article summarizes the reported literature of the role of ET-1 in the development of diabetic complications, with particular focus on the possible role of ET-1 in mediating the effects of angiotensin-converting enzyme inhibitors.

OBJECTIVES: To compare the long-term recurrence rate of the standard technique (simple sinectomy) and the supra-auricular approach (wide local excision) for the surgical management of preauricular sinuses. STUDY DESIGN: Retrospective cohort. METHODS: Fifty-four patients with a preauricular sinus excised between May 1986 and December 1996 were included in this study. All patients were categorized into one of two groups based on the type of surgery performed: the standard technique or the supra-auricular approach. The medical records were then reviewed and the latest information concerning the recurrence of a preauricular sinus were updated by phone interview. The recurrence rate of these two groups was statistically analyzed by the Fisher exact test. RESULTS: Forty-nine of 54 patients were successfully contacted with data updated and analyzed. The 32% recurrence rate of the standard excision (n = 25) was significantly higher than the 3.7% recurrence rate of the supraauricular approach (n = 27; two-tailed test, P = .01). CONCLUSION: The supra-auricular approach for excision of a preauricular sinus has a statistically lower recurrence rate in comparison to the standard technique.

This review was carried out to assess the effectiveness of our protocol designed for the management of ingested foreign bodies. It was a retrospective review of 5240 patients with ingested foreign bodies admitted over a five-year period to the Ear Nose and Throat Unit. These patients were managed according to a standardized protocol which was adopted and modified from our previous study. Under his management protocol, the mean hospital stay was 1.6 days. Flexible oesophagoscopy under local anaesthesia, and rigid oesophagoscopy under general anaesthesia, were performed in 1.5 per cent and 7.7 per cent of cases respectively. Major complications including oesophageal perforation and deep neck abscesses occurred in 0.19 per cent of patients. There was no mortality. This management protocol for ingested foreign bodies was both safe and cost-effective when compared to similar studies reported in the literature.

Endothelin is a novel potent vasoconstrictor peptide produced by a wide variety of cell types and which has diverse biological activities. Previously we have reported that thyroid hormone status alters tissue levels of immunoreactive endothelin (irET) in rats. In order to study whether plasma irET levels in humans are affected by thyroid hormone status, we measured irET concentrations by means of radioimmunoassay in plasma samples from euthyroid controls as well as from patients with either hypothyroidism or hyperthyroidism. Plasma samples from the above-mentioned three groups of subjects were collected. After extraction with Sep-Pak C18 cartridges, plasma irET levels were measured by radioimmunoassay. The plasma irET levels in the three groups of subjects did not show any significant difference. Also, no correlations were found between plasma irET levels, thyroid hormones and the thyroid-stimulating hormone thyrotropin (TSH) in euthyroid, hypothyroid and hyperthyroid subjects. These results suggest that thyroid function per se is not a major determinant of plasma irET levels in humans.

Endothelin-1 (ET-1), a 21 amino acid peptide originally purified from conditioned medium of cultures of porcine aortic endothelial cells, is recognized also as a product of many other cells such as epithelial cells, glial cells, and neurons. It is now recognized that at least ET-1 plays an important role in bone metabolism. It has been shown that ET-1 inhibits osteoclast bone resorption by a direct effect on cell motility and it can also activate phospholipase C in the osteoblast. Furthermore, several studies have shown that ET-1 stimulates the formation of inositol phosphates, the synthesis of DNA, the mobilization of calcium from extra- and intracellular pools, the activation of phospholipase D, and the stimulation of tyrosine phosphorylation in osteoblast-like (MC3T3-E1 and UMR-106) cells. The aim of the present study was to detect and characterize the presence of endothelin in transformed human osteoblast cell culture medium (HTb96) by radioimmunoassay and chromatography methods. Immunoreactive endothelin (IR-ET) was undetectable in the medium incubated at 0.5 and 1 h and was 3.2 +/- 0.2 fmol/10(5) cells (mean +/- SEM, n = 6) at 2 h, 9.5 +/- 0.5 fmol/10(5) cells at 6 h, 19.8 +/- 2.1 fmol/10(5) cells at 24 h, and 23.7 +/- 2.0 fmol/10(5) cells at 48 h, respectively. Sephadex G-25 superfine chromatography and fast protein liquid chromatography studies showed that >90% of IR-ET in the culture medium coeluted with synthetic ET-1. These results show that ET-1 could be formed by transformed human osteoblasts. Further studies should be conducted to elucidate the physiological role of endothelins as possible autocrine, paracrine, or endocrine factors in calcium and bone metabolism.

BACKGROUND: The pathogenesis of cirrhotic ascites and hepatorenal syndrome remains unresolved. The involvement of both endothelin-1 and atrial natriuretic peptide have recently been suggested. This study investigated the concentrations of serum endothelin and atrial natriuretic peptide in cirrhotic patients. METHODS: Seven healthy subjects and 31 cirrhotic patients were studied. Cirrhotic patients were divided into three groups: Group I, 16 cirrhotic patients without ascites; Group II, 10 cirrhotic patients with ascites, but without hepatorenal syndrome; and Group III, five cirrhotic patients with hepatorenal syndrome and ascites. Their sera were analyzed for endothelin-1 and atrial natriuretic peptide concentrations. RESULTS: Cirrhotic patients with ascites, Group II and Group III, had higher plasma endothelin-1 concentrations (15.9 +/- 2.3 pg/ml and 24 +/- 2.1 pg/ml, respectively) than normal subjects and compensated cirrhotics (3.8 +/- 0.7 pg/ml and 6.4 +/- 1.1 pg/ml, respectively); p < 0.001). Atrial natriuretic peptide concentrations were also significantly higher in cirrhotic patients than in normal subjects (p < 0.025). Plasma endothelin-1 concentration had a negative correlation with creatinine clearance (r = -0.65, p < 0.001), as did atrial natriuretic peptide concentrations (r = -0.44, p = 0.012). Plasma endothelin-1 correlated significantly with atrial natriuretic peptide concentrations (r = 0.38, p = 0.035). CONCLUSIONS: Both endothelin-1 and atrial natriuretic peptide concentrations were elevated in cirrhotic patients with ascites and hepatorenal syndrome. Endothelin-1 may have a negative impact on renal function. Our data also suggested that impaired responsiveness rather than impaired secretion of atrial natriuretic peptide is responsible for sodium retention in cirrhotic patients with ascites.
