Psychosocial Factors Behind Deliberate Self-Poisoning in a Tertiary Care Hospital of Bangladesh: A Cross-Sectional Study.

INTRODUCTION: Deliberate self-poisoning (DSP) is an important cause of hospital admissions and subsequent mortality. We conducted a cross-sectional observational study in a tertiary-level teaching hospital situated in the northeastern part of Bangladesh to analyze the psychosocial factors responsible for DSP. METHODS: This cross-sectional observational study was carried out among patients with DSP admitted to the medicine ward from January to December 2017, irrespective of gender, except for cases involving poisoning due to spoiled food, food contaminated by infectious organisms, poisoning by venomous animals, and street poisoning (commuter or travel-related poisoning). Consultant psychiatrist in accordance with the Diagnostic & Statistical Manual of Mental Disorder - IV (DSM-IV) confirmed psychiatric disorders. Data were analyzed by SPSS (Statistical Package for social sciences) version 16.0 (IBM Corp., Armonk, NY). RESULTS: Total 100 patients were enrolled. Among them, 43% were male and 57% were female. The majority (85%) of the patients were young, aged below 30 years. The mean age of male patients was 26.2 years and that of females was 21.69 years. Most of the DSP patients were from the lower economic class (59%). The population sample was remarkable for students (Prevalence 37%). The highest percentage of patients (33%) had their educational status at the secondary level. The common reasons for DSP were a family problem in 31% patients, quarrel with boy/girlfriend in 20%, quarrel with a spouse in 13%, quarrel with parents or other family member in 7%, failure in examination in 6%, poverty in 3%, and unemployment in 3%. Prescription medication was the most common poison material (38%), followed by insecticides (36%), household cleaners (17%), and rodenticides (8%). Seven (7%) patients reported previous deliberate self-harm events and co-morbid psychiatric disorder was present in 30% patients among them major depressive disorder was found in 60%, and schizophrenia in 23.3% cases. CONCLUSION: DSP remains a problem mainly for the young with gender ratio-favoring females. The majority of DSPs were educated up to secondary level, unmarried, residents of rural areas, student, and belonged to the lower class. Familial disharmony and quarrel with spouse or friends were the common reason behind DSP. Prescription medication and insecticides were commonly used for DSP. Psychiatric disorders, primarily depressive disorder, and schizophrenia were common in cases of DSP.

The association between temperature, rainfall and humidity with common climate-sensitive infectious diseases in Bangladesh.

Bangladesh is one of the world's most vulnerable countries for climate change. This observational study examined the association of temperature, humidity and rainfall with six common climate-sensitive infectious diseases in adults (malaria, diarrheal disease, enteric fever, encephalitis, pneumonia and bacterial meningitis) in northeastern Bangladesh. Subjects admitted to the adult medicine ward of a tertiary referral hospital in Sylhet, Bangladesh from 2008 to 2012 with a diagnosis of one of the six chosen climate-sensitive infectious diseases were enrolled in the study. Climate-related data were collected from the Bangladesh Meteorological Institute. Disease incidence was then analyzed against mean temperature, humidity and average rainfall for the Sylhet region. Statistical significance was determined using Mann-Whitney test, Chi-square test and ANOVA testing. 5033 patients were enrolled (58% male, 42% female, ratio 1.3:1). All six diseases showed highly significant (p = 0.01) rises in incidence between the study years 2008 (540 cases) and 2012 (1330 cases), compared with no significant rise in overall all-cause hospital admissions in the same period (p = 0.19). The highest number of malaria (135), diarrhea (266) and pneumonia (371) cases occurred during the rainy season. On the other hand, the maximum number of enteric fever (408), encephalitis (183) and meningitis (151) cases occurred during autumn, which follows the rainy season. A positive (P = 0.01) correlation was observed between increased temperature and the incidence of malaria, enteric fever and diarrhea, and a negative correlation with encephalitis, meningitis and pneumonia. Higher humidity correlated (P = 0.01) with a higher number of cases of malaria and diarrhea, but inversely correlated with meningitis and encephalitis. Higher incidences of encephalitis and meningitis occurred while there was low rainfall. Incidences of diarrhea, malaria and enteric fever, increased with rainfall, and then gradually decreased. The findings support a relationship between weather patterns and disease incidence, and provide essential baseline data for future large prospective studies.

Paraquat induced acute kidney injury and lung fibrosis: a case report from Bangladesh.

BACKGROUND: Since Bangladesh government issued a ban on the use of highly toxic WHO Class I pesticides, annual consumption of herbicides like Paraquat have been sharply increasing in the markets. Paraquat poisoning is an emerging public health threat and its high mortality rate is responsible for a significant number of deaths. Diagnostic limitations and unavailable sample at presentation have resulted in under-reporting and lack of awareness among the treating physicians, making Paraquat poisoning one of the most neglected toxicological emergencies. Herein, we present a case of Paraquat induced multi-organ failure and emphasis on pitfalls in the management. CASE PRESENTATION: An 18-years-old healthy male was admitted in Sylhet M.A.G Osmani Medical College Hospital with history of attempted suicide by Paraquat ingestion. On admission, he had high serum creatinine but otherwise asymptomatic. He was discharged on day 10 when his renal functions returned to normal. But On day 15, he started having respiratory symptoms-unresponsive to any of the local treatments he received, and by day 30, he developed overt lung fibrosis. We present sequential blood picture, radiographs and CT scans demonstrating Paraquat induced kidney and lung injury over the course of 30 days. CONCLUSION: Paraquat poisoning can lead to death and fatal long-term consequences. All cases of Paraquat poisoning, regardless of symptoms, must be hospitalized and observed for early detection of complications. Distribution of Paraquat should be restricted and/or banned as 38 other countries have done so, which we believe will greatly reduce poisoning related mortality.

Salbutamol in acute organophosphorus insecticide poisoning - a pilotdose-response phase II study.

BACKGROUND: Treatment of acute organophosphorus (OP) insecticide poisoning is difficult, with many patients dying despite best care. Pre-clinical studies have shown benefit from salbutamol, possibly due speeding alveolar fluid clearance or reducing bronchoconstriction. In this small pilot dose-response study, we aimed to explore whether addition of nebulized salbutamol to standard care might improve resuscitation. METHODS: We performed a single-blind phase II study comparing the effect of two different doses of nebulized salbutamol versus saline placebo, in addition to standard treatment. Primary outcome was oxygen saturations over the first 60 min of resuscitation; secondary outcomes included heart rate, incidence of dysrhythmias, time to 'atropinization', atropine dose required, and mortality. RESULT: Seventy-five patients were randomized to receive 5 mg (Salb5, n = 25) or 2.5mg (Salb2.5, n = 25) of salbutamol, or saline placebo (NoSalb, n = 25), by nebulizer. Oxygen saturations did not differ between groups over the first 60 min of resuscitation (median AUC NoSalb: 1376 [95% CI 1282 to 1470], Salb2.5: 1395 [1305 to 1486], Salb5: 1233 [1100 to 1367]; p = .9898). Heart rate was also similar across the three arms. Median time to full atropinization, and atropine dose required, were the same for all three arms (NoSalb 15.0 [10-16] min and 12.6 [8.0-13.4] mg, Salb2.5 15.0 [10-16] min and 12.6 [9.3-16.8] mg, and Salb5 15.0 [10-20] min and 12.6 [10.7-20.6] mg; p = .4805 and p = .1871, respectively). Three (12%) patients died in the Salb2.5 and Salb5 groups and two (8%) in the NoSalb group. CONCLUSION: This pilot study, within the limitations of its small size and variation between patients, found no apparent evidence that administration of nebulized salbutamol improved resuscitation of patients with acute OP insecticide self-poisoning. The data obtained provides a basis to design further studies to ultimately test the role of salbutamol in OP insecticide poisoning.

Prevalence of Irritable Bowel Syndrome (IBS), Migraine and Co-Existing IBS-Migraine in Medical Students.

INTRODUCTION: Irritable Bowel Syndrome (IBS) and migraine frequently co-exist. Stress is a major contributing factor for both. Our medical students are subjected to stress related to the implicit responsibility of courses. But the prevalence of IBS, migraine and co-existing migraine in medical students is not known. AIM: To estimate the prevalence of migraine, IBS and co-existing IBS and migraine among medical students. A Cross-Sectional Survey. MATERIALS AND METHODS: Self-reported questionnaire based study, was conducted in which migraine was defined according to International Headache Society (IHS) criteria while IBS by both Asian criteria and Rome III criteria. Both preclinical (n=142) and clinical students (n=151) of four medical colleges (government and private) of Dhaka and Sylhet district participated in the study. Statistical Analysis: Student's t-test and chi-square test were used to compare the distributions of continuous data and categorical data respectively with significance level set at 0.05 or less. RESULTS: Among the 293 students (mean age 21.09 ± 2.24 years) volunteered in the study (Males= 177), 14 (4.8%, 11 males, 3 females, p = 0.175) met the criteria for IBS with comparable prevalence among preclinical and clinical (4.2% vs. 5.3%, p = 0.787) students from both private and government institutions (2.1% vs. 7.2%, p = 0.055). IBS-D was the most prevalent subtype (n = 8, M = 6) and abdominal pain relieved by defecation (n = 11), was the most prevalent symptom. Fifty percent (n = 7) of IBS patients considered their bowel habit as normal. Among the 221 (75.4%) students with headache, only 51 (17.4%, 20 males and 31 females, p = 0.001) were diagnosed of migraine, with comparable prevalence among preclinical and clinical students (16.2% vs. 18.5%, p = 0.645). Only 17 (33%) subjects with migraine had accompanying aura. Common triggers were stress (n = 43), lack of sleep (n = 42), and daily life events. Twelve (23.5%) subjects with migraine had migraine-associated frequent disability. Only two female students with IBS-D (14.3%) had concomitant IBS and migraine. CONCLUSION: IBS and concomitant migraine - IBS prevalence was found to be low in our medical students, but migraine prevalence corresponds to other countries as well as in medical students.

Organophosphate poisoning presenting with muscular weakness and abdominal pain--a case report.

BACKGROUND: Organophosphate (OP) poisoning is the most common cause (27.64%) and has the highest death rate (13.88%) of poisoning in Bangladesh. It leads to three main syndromes notably acute cholinergic syndrome, intermediate syndrome, and delayed polyneuropathy. It rarely causes cardiac arrhythmia, pancreatitis and hepatic dysfunction. We present the case of a middle-aged Asian woman suffering from organophosphate poisoning with dual complications. CASE PRESENTATION: A middle aged Asian woman with depression was brought to emergency attention after drinking of 60 milliliter of organophosphate insecticide in a suicidal attempt. She had vomiting, excessive retching, diarrhoea, miosis, hypersalivation and bilateral crepitation on chest during admission. After immediate resuscitation, atropinization was done and it required total of 36 milligram. The patient also received pralidoxime. While on maintenance, features of toxicity re-appeared and she again required atropine in bolus dose. On the fifth day of management she complained of generalized weakness, inability to control her neck and to sit or stand without support. But there was no respiratory muscle involvement and all deep tendon reflexes were normal. On the same day the patient also developed severe upper abdominal pain along with nausea and vomiting. Investigations revealed neutrophilic leucocytosis (30,000/cubic millimeter; 86%) with high serum lipase (770 Unit/Liter) and alanine transaminase (379 Unit/Liter) and low serum potassium (3.0 millimol/Liter). On the basis of above mentioned features organophosphate induced intermediate syndrome and pancreatitis was diagnosed. The patient recovered completely with appropriate management. CONCLUSION: Organophosphate poisonings causes up to 25% mortality worldwide. A major contributing factor for that are different complications. Awareness of these complications can reduce both mortality and morbidity. Early diagnosis of complications and timely therapeutic measures can improve prognosis.

Hereditary multiple exostoses causing cord compression.

Hereditary multiple exostoses (HME) is an autosomal dominant skeletal disorder characterized by the presence of multiple osseous prominences. It can occur sporadically or within families (22 - 56%). Two genes, EXT1 and EXT2 located respectively at 8q24 and 11p11-p12, have been isolated to cause HME. It can cause gross deformity of limbs and growth disturbance which is quite a common complication. Malignant transformation to chondrosarcoma can also occur. Neurological presentations are rare and usually happened due to direct compression of a peripheral nerve or nerve root or less often the spinal cord. This case is possibly the first case of HME described from Bangladesh, presented with dorsal cord compression. Decompression was done and the complaints of myelopathy were improved.

Seroepidemiological surveillance of Burkholderia pseudomallei in Bangladesh.

Melioidosis (Burkholderia pseudomallei infection) has yet to be demonstrated systematically in Bangladesh. A prospective, cross-sectional serological survey was conducted in 2010 at six Bangladeshi hospitals. Age, gender, occupation and residential address were recorded. Of 1244 patients, 359 (28.9%) were positive for B. pseudomallei by indirect haemagglutination assay. Farmers had an increased risk of seropositivity (risk ratio=1.4, 95% CI 1.0-1.8; p=0.03). There was no clear geographic clustering of seropositives. Melioidosis should be considered as a possible cause of febrile illness in Bangladesh. Further studies are needed to establish the incidence of clinical disease and distribution of environmental risk.
