Lifestyle management of hypertension: International Society of Hypertension position paper endorsed by the World Hypertension League and European Society of Hypertension.

Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools.

Hemophagocytic lymphohistiocytosis as a rare complication of dengue haemorrhagic fever: a case report.

BACKGROUND: Haemophagocytic lymphohistiocytosis (HLH) is an uncommon systemic inflammatory syndrome that can happen secondary to numerous conditions. It rarely occurs due to dengue infection causing significant mortality and morbidity even with appropriate treatment. The outcome is further poor if the diagnosis of HLH is delayed or left untreated. Therefore, a high degree of clinical suspicion is paramount in diagnosing HLH. CASE PRESENTATION: A 17-year-old Sinhalese boy was admitted to a tertiary care hospital in Sri Lanka with a 4-day history of fever, headache, nausea, vomiting, and diarrhea. He was hemodynamically stable, and the serological investigation confirmed a dengue infection. On the fifth day of fever, he entered the critical phase of dengue infection, confirmed by ultrasound evidence of plasma leaking. However, he had ongoing high fever spikes during the critical phase, and even after the critical phase was over, the fever spikes continued. Simultaneously, hepatosplenomegaly was noticed, and he showed persistent thrombocytopenia, neutropenia, and anemia despite the resolution of the critical phase. Further, the workup revealed a serum ferritin level of > 3000 ng/mL triglyceride level of 314 mg/dL, and the bone marrow biopsy revealed an increased haemophagocytic activity. Secondary HLH was diagnosed on the basis of criteria used in the HLH-2004 trial and successfully managed with intravenous dexamethasone 10 mg/body surface area/day for the first 2 weeks, followed by a tapering regimen over 8 weeks. CONCLUSION: This case emphasizes the need to consider HLH as a potential complication when persistent fever and cytopenias are present after recovering from dengue fever, particularly in patients with unusual clinical features like hepatosplenomegaly. Early recognition and prompt treatment with appropriate immunosuppressive therapy, such as intravenous dexamethasone, can lead to a successful response and good prognosis.

Blood transfusion in severe dengue infection: a case series.

BACKGROUND: Dengue is still a recurrent challenge to the global population, without specific antiviral therapy. Clinical management strategies are aimed to mitigate the deaths. The use of blood products in dengue is recommended mainly in cases of bleeding. CASE PRESENTATION: We prospectively collected data on Sri Lankan dengue cases in the Teaching Hospital, Peradeniya, Sri Lanka from 2017, and selected ten severe cases where blood transfusions were involved in the management. The series comprises seven females and three males, with a median age of 36 years (range 12-53 years). All patients were critically ill at the time of blood transfusion, with dramatic stabilization of vital parameters after the transfusions. Only one patient had detectable bleeding, while five patients had occult blood loss as indicated by dropping hematocrit. Even though four patients had stable hematocrit, they had metabolic acidosis. Two patients had a very high increase of hepatic transaminases along with acidosis. Two patients had myocarditis with dropping hematocrit, suggestive of occult bleeding. CONCLUSIONS: Clinical deterioration despite fluid management commonly occurs due to occult bleeding in dengue infection. Blood transfusion is lifesaving in such cases of blood loss, acidosis, and severe hepatic damage. The mechanism of this effect needs an explanation, such as enhanced oxygen delivery to the tissues and hemostasis to hypothesize a few possibilities.

Addressing global disparities in blood pressure control: perspectives of the International Society of Hypertension.

ABSTRACT: Raised blood pressure (BP) is the leading cause of preventable death in the world. Yet, its global prevalence is increasing, and it remains poorly detected, treated, and controlled in both high- and low-resource settings. From the perspective of members of the International Society of Hypertension based in all regions, we reflect on the past, present, and future of hypertension care, highlighting key challenges and opportunities, which are often region-specific. We report that most countries failed to show sufficient improvements in BP control rates over the past three decades, with greater improvements mainly seen in some high-income countries, also reflected in substantial reductions in the burden of cardiovascular disease and deaths. Globally, there are significant inequities and disparities based on resources, sociodemographic environment, and race with subsequent disproportionate hypertension-related outcomes. Additional unique challenges in specific regions include conflict, wars, migration, unemployment, rapid urbanization, extremely limited funding, pollution, COVID-19-related restrictions and inequalities, obesity, and excessive salt and alcohol intake. Immediate action is needed to address suboptimal hypertension care and related disparities on a global scale. We propose a Global Hypertension Care Taskforce including multiple stakeholders and societies to identify and implement actions in reducing inequities, addressing social, commercial, and environmental determinants, and strengthening health systems implement a well-designed customized quality-of-care improvement framework.

The Role of Serum NT-proBNP for Predicting Left Ventricular Systolic Dysfunction in Hospitalized Patients in Sri Lanka.

Background/aims: Only a few studies have addressed the role of NT-proBNP in identifying Left Ventricular Systolic Dysfunction (LVSD) in South Asian populations. Therefore, the current study was aimed at assessing the use of serum NT-proBNP in predicting LVSD in a hospitalized population in Sri Lanka. Methods: A random sample of 278 individuals referred for echocardiography at a major Teaching Hospital consented for venous blood samples to be collected for serum NT-proBNP assay by sandwich ELISA. Based on the ejection fraction (LVEF) and fractional shortening (FS), participants were differentiated as LVSD (LVEF<50%, FS≤ 29%) and non-LVSD individuals (LVEF>60%). According to inclusion/exclusion criteria, the final study sample consisted of 100 LVSD patients and 41 non-LVSD individuals. Results: The mean ages of the LVSD and non-LVSD groups were 69.1 (±6.2 years) and 71.4 (±2.4 years) (p=0.066) respectively. The median NT-proBNP value (with IQR) among LVSD patients (528.2 pg/mL,355.2-924.2) was comparatively higher than that of non-LVSD individuals (207.3 pg/mL,177.5-343.0). Strong correlations of NT-proBNP level with LVEF (Spearman rho= -0.84, p<0.001) and FS (rho= -0.81, p<0.001) suggested that serum NT-proBNP concentration increases in parallel to deteriorating left ventricular functions. The AUROC of serum NT-proBNP for differentiating LVSD was 0.859 (95% CI:0.79 - 0.92) and the optimal cut-off level for predicting LVSD was 265pg/mL, with 90% sensitivity and 70% specificity. Conclusion: Current Sri Lankan study revealed a considerable correlation of serum NT-proBNP level with LVSD and utilizing such an assay for screening will facilitate adequate evidence to rule-out LVSD among high-risk residents.

Pure red cell aplasia secondary to rheumatoid arthritis: a case report.

BACKGROUND: Rheumatoid arthritis is a common autoimmune disease with many extra-articular manifestations. Pure red cell aplasia is a rare manifestation of rheumatoid arthritis and is sparsely documented in the literature, with a variable clinical outcome following immunosuppressive therapy. CASE PRESENTATION: A 63-year-old Sinhalese female presented with transfusion-dependent anemia associated with deforming inflammatory arthritis. She also had leukopenia, right subclavian venous thrombosis, and generalized lymphadenopathy. The diagnosis of rheumatoid arthritis following initial clinical workup and additional blood and bone marrow investigations revealed pure red cell aplasia as a secondary manifestation of rheumatoid arthritis after excluding other secondary causes, such as infections, thymoma, thrombophilic conditions, and hematological malignancy. She responded well to oral prednisolone, cyclosporine A, and hydroxychloroquine, and she attained complete recovery in 2 months. CONCLUSION: Pure red cell aplasia is a disabling illness that may lead to transfusion-dependent anemia, which may occur due to rare extrapulmonary manifestation of rheumatoid arthritis. The diagnosis of pure red cell aplasia secondary to rheumatoid arthritis may be challenging where hematological investigations, including bone marrow biopsy, will aid in the diagnosis, and early diagnosis and treatment will bring about a better outcome.

Kounis Syndrome Secondary to Medicine-Induced Hypersensitivity.

INTRODUCTION: Kounis syndrome is the concurrence of an acute coronary syndrome (ACS) caused by coronary vasospasms, acute myocardial infarctions, or stent thromboses in case of allergic or hypersensitivity reactions. Kounis syndrome is mediated by mast cells that interact with macrophages and T-lymphocytes, causing degranulation and inflammation with cytokine release. It is a life-threatening condition that has many trigger factors and is most commonly caused by medicines. Case Presentation. A 71-year-old male was admitted with a fever of five days' duration associated with cellulitis, for which he had been treated with clindamycin and flucloxacillin before admission. He was a diagnosed patient with hypertension and dyslipidemia five years ago. After taking the antibiotics, he had developed generalized itching followed by urticaria suggesting an allergic reaction. Therefore, he was admitted to the hospital. After admission, he developed an ischaemic-type chest pain associated with autonomic symptoms and shortness of breath. An immediate ECG was taken that showed ST-segment depressions in the chest leads V4-V6, confirmed by a repeat ECG. Troponin I was 8 ng/mL. Acute management of ACS was started, and prednisolone 10 mg daily dose was given. After complete recovery, the patient was discharged with aspirin, clopidogrel, atorvastatin, metoprolol, losartan, isosorbide mononitrate, and nicorandil. Prednisolone 10 mg daily dose was given for five days after discharge. CONCLUSION: In immediate hypersensitivity, with persistent cardiovascular instability, Kounis syndrome should be considered, and an electrocardiogram and other appropriate assessments and treatments should be initiated. Prompt management of the allergic reaction and the ACS is vital for a better outcome of Kounis syndrome.

Hypertension Knowledge, Attitude, and Practice in Adult Hypertensive Patients at a Tertiary Care Hospital in Sri Lanka.

OBJECTIVE: Hypertension (HTN) remains a major risk factor for cardiovascular diseases globally. Despite considerable improvement in increasing awareness, treatment, and control of HTN, undiagnosed and uncontrolled HTN remains a major public health challenge. Our focus was on studying the knowledge, attitude, and practice regarding HTN in adult hypertensive patients at a tertiary care hospital in Sri Lanka. Methodology. A descriptive study on knowledge, attitude, and practice of hypertensive patients on antihypertensive medications attending the hypertensive clinic was carried out from January 2016 to June 2016 at THP. RESULTS: The study was on a total of 371 hypertensive patients comprising 253 (68.2%) females and 118 (31.8%) males. Among the total participants, 12 (3.2%), all females, had never been to school. About half of them (47.7%) had not even reached GCE (ordinary level). More than two-thirds (77%) of the study population were aware of the complications of HTN as they were informed by a health care team member. About 74% of them were taking all their prescribed medications. Almost all (95%) patients had checked their blood pressure (BP) during the previous 12 months, and almost the same percentage had visited their doctor for BP checkups every 1-3 months. CONCLUSION: Our patients were well aware of the importance of regular follow-ups and also knowledgeable about the complications related to HTN. Almost 75% of the patients had optimum drug compliance. It was revealed that forgetfulness was the frequent cause for poor drug compliance.

Too Aggressive Drop in Blood Pressure in a Hypertensive Male Leading to "Man-in-the-Barrel Syndrome".

INTRODUCTION: "Man-in-the-barrel syndrome" is a neurological phenotype with brachial diplegia, normal sensation, and preserved motor function of the lower limb. It has been described in various neuropathological conditions affecting the cerebral hemispheres, pons, upper spinal cord, and peripheral neurons. Severe hypotension leading to watershed infarctions leading to this phenotype has been reported. We describe the first case of "man-in-the-barrel syndrome" in a patient with a precipitous drop in blood pressure following oral antihypertensive medications. Case Presentation. A 75-year-old Sri Lankan male presented following a generalized tonic-clonic seizure to a tertiary care hospital. Upon recovery, he was noted to have severe brachia diplegia affecting shoulder movements with preserved hand muscle power and motor functions of the lower limb. The previous day, he was newly diagnosed with markedly elevated blood pressure without acute end organ involvement. Treatment with three antihypertensives had been initiated. Noncontrast CT of the brain revealed watershed infarctions affecting both cerebral hemispheres. CONCLUSION: It is generally unwise to lower blood pressure very rapidly, as ischemic damage can occur in vascular beds that are habituated to high levels of blood pressure in the brain. Ischemic damage caused by rapid lowering of blood pressure may rarely result in "man-in-the-barrel syndrome" leading to severe functional disability.

Young Male Presenting with an Acute Diarrheal Illness with Unexplained Transudative Ascites: An Atypical Presentation of Appendicular Tuberculosis.

INTRODUCTION: Appendicular tuberculosis is a rare form of extrapulmonary tuberculosis involving the gastrointestinal tract. Diagnosis of appendicular tuberculosis is difficult due to its atypical presentation. Histological confirmation remains the gold standard in diagnosis. Case Presentation. We report a 37-year-old Sri Lankan male presenting with a diarrheal illness with high fever for 8 days in the background of constitutional symptoms for 1-month duration. He was pale and had moderate amount of free fluid in the abdomen. Inflammatory markers were elevated, and CT abdomen revealed a thickened elongated appendix. Diagnostic paracentesis revealed a lymphocytic transudative ascites. A macroscopically minimally inflammed appendix removed at laparotomy and histology confirmed presence of tuberculous granulomata with caseation. He made an uneventful recovery by the anti-tuberculous therapy. CONCLUSION: High degree of suspicion is needed in diagnosis of appendicular tuberculosis due to its nonspecific presentation, and we emphasize the need of histological assessment of the appendix resected for the case of clinical appendicitis, as it may prompt the diagnosis of a rare but treatable case of tuberculosis.

Epidemiology and risk factors of patients with types of acute coronary syndrome presenting to a tertiary care hospital in Sri Lanka.

BACKGROUND: Acute Coronary Syndrome (ACS) is one of the leading causes of death worldwide and studies have shown higher mortality rates and premature death in South Asian countries. The occurrence and effect of risk factors differ by type ofACS.Epidemiological studies in the Sri Lankan population are limited. METHODS: This is a cross sectional descriptive study conducted at the Teaching Hospital Peradeniya, Sri Lanka among patients presenting with ACS. Data was collected by an interviewer administered structured questionnaire and epidemiological patterns and risk factors were analyzed. RESULTS: The sample of 300 patients had a mean age of 61.3+/- 12.6 and male sex showed higher association with all three type of ACS compared to female with a P value of 0.001. This study showed higher mean age of 62.2 ± 11.4 years amongst unstable angina (UA) patients and 61.9 ± 14.5 years amongst non ST elevation myocardial infarction (NSTEMI) patients compared to 59.2 ± 11.2 years for ST elevation myocardial infarction (STEMI) patients with no significant statistical difference (P = 0.246). Approximately 55.8% STEMI patients, 39.8% UA and 35.5% NSTEMI patients were smokers indicating a significant association between smoking and STEMI (P = 0.017). Nearly 54.5% STEMI, 35.4% UA and 32.7% NSTEMI patients consumed alcohol and there was a very strong association between alcohol consumption and STEMI (P = 0.006). Almost 51.8% NSTEMI patients, 47.8% UA patients and 29.9% STEMI patients had hypertension(HT) (P = 0.008) indicating significant association of HT with UA and NSTEMI. About 33.6% UA patients and 30.0% NSTEMI patients had DM whilst only 22.1% of STEMI patients had DM of no significance (p = 0.225). Around 15.0% patients with UA, 25.5% with NSTEMI and 11.7% with STEMI had dyslipidemia (P = 0.032). There was a very strong association between a past history of ACS or stable angina with NSTEMI and UA (P = 0.001). CONCLUSION: Smoking and alcohol abuse are significantly associated with STEMI.Patients with NSTEMI or Unstable Angina had higher rates of hypertension and were more likely to have a history of ACS or stable angina than STEMI patients. Patients with NSTEMI were more likely than patients with STEMI or UA to have dyslipidemia.

Guillain-Barré syndrome with associated unilateral ptosis without ophthalmoplegia - a rare presentation: a case report and review of the literature.

BACKGROUND: Guillain-Barré syndrome is an acute inflammatory polyradiculoneuropathy. Nearly half of patients with Guillain-Barré syndrome have cranial nerve involvement. However, isolated bilateral ptosis without ophthalmoplegia is a rare manifestation, and isolated unilateral ptosis without ophthalmoplegia in Guillain-Barré syndrome has not previously been reported in the literature. Furthermore, only few cases of Guillain-Barré syndrome with cranial nerve enhancement visualized by gadolinium-enhanced magnetic resonance imaging have previously been reported. We describe the first reported case of unilateral ptosis without ophthalmoplegia in Guillain-Barré syndrome and associated multiple cranial nerve enhancement seen by gadolinium-enhanced magnetic resonance imaging. CASE PRESENTATION: Our patient was a 55-year-old Sinhalese man who was admitted to a tertiary care hospital in Sri Lanka with acute-onset progressive weakness in the lower limbs followed by the upper limbs. He had bilateral symmetrical flaccid quadriparesis with absent reflexes and flexor plantar response. Left-sided isolated partial ptosis without associated ophthalmoplegia was noted with normal pupils. The patient's neurological examination was otherwise normal. A nerve conduction study showed a severe demyelinating type of polyneuropathy. No decremental response to repetitive nerve stimulation was observed, and the result of a single-muscle-fiber electromyogram was negative. A diagnosis of Guillain-Barré syndrome was made, and the patient was treated with intravenous immunoglobulin. His condition gradually deteriorated over the next few days, and he became quadriplegic despite the completion of immunoglobulin therapy. Later he developed multiple cranial nerve palsies, including bi-lateral lower motor neuron type facial nerve palsy, and he required mechanical ventilation. By this time, he had complete left-sided ptosis with a normal right eye. He never developed ophthalmoplegia or ataxia. Magnetic resonance imaging of the brain showed contrast enhancement in the intracranial part of multiple cranial nerve roots and basal leptomeninges. He gradually improved with plasmaparesis, and ptosis was the first to improve. CONCLUSIONS: Even though Guillain-Barré syndrome was recognized a century ago, there are still many unanswered questions about it and its florid presentation. Large-scale studies are needed for better understanding of its pathophysiology and prototypes and to find answers for still-unanswered questions. The clinician must have a high index of suspicion and be familiar with mimics and prototypes to diagnose Guillain-Barré syndrome accurately without delay.

Infective myositis, an uncommon presentation of melioidosis: a case report and review of the literature.

BACKGROUND: Melioidosis is considered endemic in certain areas of the world. Musculoskeletal and soft tissue involvement are relatively uncommon presentations in melioidosis. We present a case of infective myositis in a patient with melioidosis in Sri Lanka, which is not considered an endemic country. Even though multiple cases of melioidosis have been reported with an increasing number in Sri Lanka, infective myositis secondary to melioidosis was not reported previously. CASE PRESENTATION: A 60-year-old Sinhalese man with diabetes presented with fever of 4 months' duration and a limp with a painful lump on the right side of the upper thigh of 2 months' duration. He had been treated in a local hospital for community-acquired pneumonia 3 weeks prior to this admission, for which he had received intravenous meropenem and teicoplanin with intensive care unit admission. He had a 0.5-cm × 0.5-cm tender lump over the right vastus lateralis muscle, and contrast-enhanced computed tomography of the area showed an ill-defined, heterogeneously enhancing, hypodense area involving the vastus lateralis, vastus intermedius, and quadratus femoris, suggestive of infective myositis but without abscess formation. Histopathology of the muscle biopsied from the vastus lateralis showed suppurative inflammation of subcutaneous fat with connective tissue necrosis and muscle infiltrated by lymphocytes. These features are suggestive of infective myositis possibly due to melioidosis. Although the result of a culture taken from the muscle biopsy was negative, the patient's antibody titer was strongly positive for melioidosis. He did not show any other areas with infected foci. He was treated with intravenous meropenem for 2 weeks and responded well. He was discharged with trimethoprim-sulfamethoxazole for 6 months as a maintenance therapy. CONCLUSION: Melioidosis is commonly an undiagnosed disease that has a wide variety of clinical presentations. Myositis in melioidosis is uncommon, and careful evaluation is mandatory to avoid misdiagnosis of this treatable but fatal disease. The clinician should have a high index of clinical suspicion, and further clinical and epidemiological studies are needed to determine the true burden of the disease.

Analysis and identification of symptoms and risk factors in a cohort of chronic hypertensive patients in a tertiary care hospital in Sri Lanka.

BACKGROUND: Hypertension (HT) is identified as a highly prevalent cardiovascular risk factor and also as a separate disease entity, leading to significant mortality and morbidity. The rate of HT is increasing worldwide with a faster rate identified in developing countries. Thus, it is important to evaluate epidemiological patterns of chronic HT in a developing country like Sri Lanka. METHODOLOGY: This is a cross-sectional descriptive study conducted at the Teaching Hospital Peradeniya, Sri Lanka, to assess symptoms and risk factors among patients with chronic HT. RESULTS: In a cohort of 266 chronic hypertensives, the mean values for age of population, age of onset, and duration of HT, respectively, are 63, 45, and 8 years. At presentation, 24.8% were asymptomatic. The commonest presentation at diagnosis was dizziness accounting for 33.8% cases, followed by chest pain, headache, loss of consciousness, and shortness of breath accounting for 7.5%, 13.5%, 2.6%, and 4.5%, respectively. Approximately 36.5% of patients had a positive family history. Fathers of 7.1% patients, mothers of 19.2%, and both parents of 10.2% patients had HT. 38.7% of patients had one or more siblings with HT. 34.6% had diabetes mellitus. CONCLUSION: Symptoms of those with HT are mostly nonspecific and should be considered as possible warning signs prior to the development of sinister complications of the disease. Family history of HT with affected siblings, or one of the parents, was, observed in more than one-third of patients. Early screening and prevention of modifiable risk factors are important in these patients to prevent debilitating complications.

Heart and liver are infected in fatal cases of dengue: three PCR based case studies.

BACKGROUND: Dengue is a global problem mainly in the tropics. Meticulous clinical management of cases has reduced the death rate significantly, but large numbers of people still succumb to severe complications of the infection. Presence of myocarditis is often overlooked leading to a poor outcome. Clinical management guidelines of dengue do not stress the importance of myocarditis as a manifestation in dengue infection. Severe hepatic dysfunction also needs emphasis. CASE PRESENTATION: We present three patients who had come to hospital on the 3rd day of fever. Two of them (case 1 and 3) were in shock on admission and case 2, who was stable on the3rd day, went into the critical phase and developed shock while in the hospital on the 4thday. All three had tachycardia on admission that got worse with time. The clinical course was unstable with fluctuations in urine output and deterioration of organ function. Despite frequent monitoring and life support they survived only 2-3 days in hospital. All three patients had myocarditis during the critical phase. In the first case, myocarditis was confirmed by troponin estimation and echocardiogram. In the second and third cases, histopathology confirmed myocarditis. Haemorrhagic necrosis of the liver was found in case 2 and 3 with exponential rise of transaminases. In all three cases, viral RNA was detected in both heart and liver tissues by PCR amplification. CONCLUSIONS: We stress that detection of myocarditis and liver involvement in any dengue patient is important from the onset of the illness where treatment should be tailored to prevent development of hypotension. Our findings are novel as PCR and histology are rarely done on tissues of deceased dengue patients in the world. Studies are needed to find therapeutic interventions to reverse cardiac and hepatic dysfunction in dengue infection.

Series of 10 dengue fever cases with unusual presentations and complications in Sri Lanka: a single centre experience in 2016.

BACKGROUND: Dengue has global importance as a dreaded arboviral infection. It has 4 serotypes of epidemiological imporatnce. The classification denotes two clinical spectrums- dengue fever (DF) and dengue haemorragic fever (DHF). Most cases are stereotype and amenable to fluid resuscitation. However, unusual manifestations cause fatalities and often overlooked. This study describes 10 such dengue cases to fill the knowledge gaps. CASE PRESENTATION: All 10 patients presented to the Teaching Hospital, Peradeniya, Sri Lanka during mid-year epidemic of dengue in 2016. The mean age is 27 years (range 12-51 years) comprising 6 females and 4 males. The group had 7 DHF, 3 DF and 2 primary dengue infections who predominantly had severe bleeding into gut. Other potentially life threatening problems were acute severe hepatitis, severe septic shock, myocarditis, erratic rapid plasma leak, intracranial bleeding, diarrhoea and decompenstaed dengue shock due to 3rd space fluid leak. Blood transfusions and other empirical therapeutic methods were used apart from meticulous fluid management to suit issues of each patient. Bedside ultrasound scanning helped early detection of critical phase. All recovered fully. CONCLUSIONS: Dengue is an extremely challenging infection to treat in the globe today. Above unusual presentation and complications could be fatal, if not detected early where therapeutic window period is very short. Clinicians need awareness of these problems which are not uncommon, but underreported and often overlooked. The clinical management of each patient was described for the purpose sharing the experiences.

Unilateral pulmonary edema: a case report and review of the literature.

BACKGROUND: Unilateral pulmonary edema is an uncommon condition and is a rare clinical entity that is often misdiagnosed at the initial stages. In a majority of patients it occurs in the upper lobe of the right lung. There are many causes of unilateral pulmonary edema, but the commonest is the presence of a grade 3 mitral regurgitation. Due to its rare presentation, a high index of suspicion is required, and correct management is necessary to reduce the morbidity and mortality. CASE PRESENTATION: We present a case of right-sided unilateral pulmonary edema in an 86-year-old Sinhalese Sri Lankan woman who presented with acute onset dyspnea with cardiogenic shock due to acute non-ST elevation myocardial infarction, complicated with grade 3 mitral regurgitation. She had clinical features of heart failure and pulmonary edema, but a chest X-ray showed unilateral infiltrates only on the right side. Distinguishing pneumonia from pulmonary edema according to chest X-ray findings was a challenge initially, and she was therefore initially treated for both conditions. She had remarkable clinical and radiological improvement after 12 hours of intravenously administered furosemide and glyceryl trinitrate therapy. Her brain natriuretic peptide level was elevated and further supported and confirmed the diagnosis retrospectively. CONCLUSIONS: Unilateral pulmonary edema is a completely reversible condition with good patient outcome if it is suspected early and treated early. Even in the absence of readily available echocardiogram skills, a clinical examination is of paramount importance in making a clinical decision in low-resource settings to reduce mortality.

Value of peripheral blood count for dengue severity prediction.

OBJECTIVE: This retrospective study was conducted in 2017 with the objective of evaluating the value of acute phase peripheral blood parameters in predicting dengue haemorrhagic fever (DHF). Patients, who were admitted to Teaching Hospital Peradeniya between January and August 2017 due to dengue illness, were recruited into this study. RESULTS: A total of 515 patients participated in the study. Among them, 333 were DHF patients while 182 patients were managed as DF. There was a significant difference in mean values of platelets and haemoglobin observed during acute phase in non-leakers compared to the patients who progressed to DHF, while no significant difference was observed for white blood cells, neutrophils, lymphocytes and haematocrit values. A significantly higher mean value was observed in white blood cells and hemoglobin in leakers compared to non-leakers during day 5. Mean day 5 platelet value was significantly lower among leakers compared to non-leakers but no significant difference between haematocrit, neutrophil and lymphocyte values were observed. ROC curve performed for acute phase platelet values and haemoglobin values to gain a predictive value for female and male DHF patients and cut off values with high sensitivity and specificity to predict DHF could be obtained for the platelet count.

A case of acute necrotizing pancreatitis complicated with non ST elevation myocardial infarction.

BACKGROUND: Acute pancreatitis is an inflammatory condition with varying severity and a range of local and systemic complications. Here we report a patient with acute necrotizing pancreatitis complicated with a true non ST elevation myocardial infarction. CASE PRESENTATION: A 58 year old lady was admitted to our unit with acute onset epigastric pain and vomiting for 4 h duration. Following admission she complained of retrosternal tightening type of a chest pain. She had elevated serum amylase and cardiac troponin. Electrocardiogram (ECG) revealed lateral ischaemia. Contrast computerized tomography abdomen revealed acute severe necrotizing pancreatitis. CONCLUSIONS: Nonspecific ECG changes can occur in patients with acute pancreatitis. But the diagnosis of true myocardial infarction in a context of acute pancreatitis using ECGs, 2D echocardiography, cardiac biomarkers and coronary angiograms can be challenging with the choice of revascularization therapy and safety of antiplatelet agents and anticoagulant therapy. Decision making regarding the management of such a patient is also critical.

Epidemiology of newly diagnosed hypertensives in a tertiary care hospital in a developing country.

BACKGROUND: Cardiovascular diseases are the main cause of death in most countries and the past two decades have shown a global increase. Hypertension (HTN) was found to be the leading risk factor in 2010 as qualified by Disability Adjusted Life Years. Epidemiological studies in this regard in Sri Lanka are scarce. Thus, describing epidemiological patterns of HTN in the Sri Lankan population will help policy makers in planning preventive healthcare programs and aid in preparing strategies to cope with the increasing demand for healthcare facilities. METHODS: This is a cross-sectional descriptive study conducted at the Teaching Hospital Peradeniya, Sri Lanka, among newly diagnosed hypertensives according to the JNC 7 report, attending the hypertensive clinic through referral. Data were collected by an interviewer administered structured questionnaire, and epidemiological patterns were analyzed. RESULTS: Among 244 newly diagnosed hypertensives, the mean age was 58.3 years (SD = 12.3) and the majority were females. 66.8% had stage 2 HTN (>160 mmHg) at the time of first presentation to a tertiary care center. There was no statistically significant difference of the stage of HTN based on sex, education level, occupation, marital status, consumption of alcohol, and smoking. CONCLUSION: Majority of the population had very high blood pressure at first diagnosis, indicating delay in the detection of HTN at an early stage. Therefore, measures to increase the probability of early detection of HTN will be useful in reducing morbidity and mortality associated with HTN.
