Efficacy of high dose Allopurinol in reducing left ventricular mass in patients with left ventricular hypertrophy by comparing its efficacy with Febuxostat - a randomized controlled trial.

OBJECTIVE: : To determine the efficacy of high-dose allopurinol in reducing left ventricular mass in patients with left ventricular hypertrophy by comparing its efficacy with febuxostat.. METHODS: The randomised controlled interventional study was conducted at Mayo Hospital, Lahore, Pakistan, from April to December 2015, comprising patients with left ventricular hypertrophy on echocardiography. They were randomly divided into two equal groups, with Group A receiving allopurinol and Group B receiving febuxostat. Primary endpoint was reduction in left ventricular mass and left ventricular mass index as calculated by echocardiography. Patients were followed at third and sixth month of enrolment to detect regression. Patients were investigated for eosinophil's count, urine for micro albuminuria and renal function tests to monitor side effects of allopurinol. SPSS 20 was used for data analysis. RESULTS: There were 76 patients divided into two groups of 38(50%) each. Mean reduction in left ventricular mass between baseline and at six months in Group A and Group B was 35.474±13.54 and 21.921±3.33 respectively (p=0.0001) while mean reduction in left ventricular mass index between baseline and at six months was 17.26±4.36 and 17.63±21.07 respectively (p=0.0001). Greater improvement was observed in Group A.. CONCLUSIONS: Allopurinol was found to be more effective than febuxostatin reducing the left ventricular mass and left ventricular hypertrophy independent of blood pressure.

Presence of pre-diabetes in Helicobacter pylori positive versus Helicobacter pylori negative patients having dyspepsia.

Pre-diabetes is a state of intermediate hyperglycaemia. Helicobacter (H) pylori infection is an established risk factor for pre-diabetes. This comparative cross-sectional study was done in Mayo Hospital Lahore from November 2015 to August 2016 in which 270 patients underwent upper gastrointestinal endoscopy with antral biopsy. An oral glucose tolerance test was done half to one hour after endoscopy. Patients were diagnosed having pre-diabetes according to American Diabetic Association criteria. Cases were divided into Group A and B based on the presence or absence of histopathological evidence of H. pylori respectively. Comparison was done to see the occurrence of pre-diabetes in H. pylori positive versus helicobacter negative dyspeptic patients. Results showed that 79 (58.52%) in Group-A and 62 (45.93%) in Group-B had pre-diabetes while remaining 56 (41.48%) in Group-A and 73 (54.07%) in Group-B had no findings of this morbidity, p value was calculated as 0.03 showing a significant difference. It was concluded that H. pylori infection is significantly associated with pre-diabetes.

Dengue fever in Pakistan: a paradigm shift; changing epidemiology and clinical patterns.

Dengue fever has huge public health implications and affects over 100 million people worldwide. This review pictures the current situation of Dengue in Pakistan and presents a review of published literature. Pakistan has seen recurrent epidemics of Dengue Fever recently. Unfortunately, these epidemics are becoming more severe in their clinical manifestation. Pakistan experienced large epidemics of dengue fever during 2008, 2010 and 2011 affecting thousands of people and claiming hundreds of deaths. A comparison of data during these epidemics indicates a shift from mild to a more severe disease, which could be interpreted as an epidemiologic transition pattern in the country. Expansion of Dengue in Pakistan seems to be multifactorial, including the climate change, frequent natural disasters, vector resistance to insecticides and lack of resources. This highlights the need for rigorous vector control. Continuing education of primary care physicians is crucial for early appropriate management to reduce mortality.

Paradoxical respiratory sinus arrhythmia due to a large thoracic empyema in an ambulatory patient.

We report a case of paradoxical respiratory sinus arrhythmia (PRSA) caused by a retro-cardiac empyema in an ambulatory patient. The case describes the dynamics and deleterious impact of PRSA on cardio-respiratory cycle, its electrocardiographic, radiologic and echocardiographic findings. Furthermore, it discusses a probable mechanism of paradoxical respiratory sinus arrhythmia in the setting of a retrocardiac mass and suggests a need for physicians to check for the changes in ventilation perfusion mismatch and rise in physiological dead space in such patients. In conclusion, to the best of our knowledge, this is the first documented report of paradoxical respiratory sinus arrhythmia in an ambulatory, non-anesthetized spontaneously breathing patient.

An unusual cause of acute abdominal pain in dengue fever.

Dengue fever is an acute febrile viral disease caused by the bite of Aedes aegypti mosquito. It is a major health problem especially in tropical and subtropical areas including South East Asia and Pakistan. In the past few years, dengue fever has been endemic in Northern Punjab. Physicians managing dengue fever come across varied and uncommon complications of dengue fever. We report a case of dengue fever that developed severe right upper quadrant abdominal pain and induration after extreme retching and vomiting for 2 days. A rectus sheath hematoma was confirmed on noncontrast computed tomography (CT). Rectus sheath hematoma as a complication of dengue fever has rarely been reported before and never from this part of the world. Rectus sheath hematoma is an uncommon and often clinically misdiagnosed cause of abdominal pain. It is the result of bleeding into the rectus sheath from damage to the superior or inferior epigastric artery or their branches or from a direct tear of the rectus muscle. It can mimic almost any abdominal condition (See Fig.) (See Table).

An unusual cause of stroke in a young female.

Takayasu arteritis is a granulomatous vasculitis of medium- to large-sized arteries. Initial presentation is usually with nonspecific constitutional symptoms, but unusually, it can present with acute ischemic features in the advanced disease. We present a case of a young Asian female who presented with acute stroke due to Takayasu arteritis. Involvement of proximal arteries was a source of embolism, which was the most likely cause of stroke in this patient. Patient made a good clinical recovery with a combination of medical treatment and rehabilitation. Takayasu arteritis should be considered as a possibility in all young patients presenting with stroke, as this is fairly responsive to medical management and associated with good clinical outcomes.

Effect of intravenous mannitol in mobilization of resistant cirrhotic ascites.

INTRODUCTION: Cirrhotic ascites is conventionally treated with bed rest, salt restriction, and diuretics. In 20-30% of patients it eventually became resistant to diuretic therapy partly because of reduced sodium excretion owing to the development of resistance against atrial natriuretic peptide. Diuretics resistance can be overcome partially by increasing distal tubular sodium delivery by atrial natriuretic peptide and mannitol administration. OBJECTIVES: To determine the short-term response of intravenous mannitol administration on mobilization of resistant cirrhotic ascites in addition to conventional diuretic treatment. STUDY DESIGN: It was an interventional, experimental (double-blind randomized controlled) study conducted in the medical department of Jinnah Hospital, Lahore. A total of 60 patients meeting inclusion and exclusion criteria were included in the study, 30 each in mannitol and placebo groups. Patients were followed for 5 days after the administration with mannitol or placebo. Main outcome measures were increase in 24 h urinary sodium, increase in urinary volume, decrease in weight and abdominal girth. RESULTS: Data showed that all the parameters of response, that is increase in 24 h urinary sodium (cases 34.09±16.71 vs. control 19.16±13.22, P=0.000), increase in urinary volume (cases 260.00±73.58 vs. control 91.67±43.71) decrease in weight (cases 3.07±1.14 vs. control 2.3±1.08, P=0.010) and decrease in abdominal girth (cases 4.70±2.86 vs. control 2.07±1.41, P=0.000) on day 5 of treatment were in favor of mannitol administration. CONCLUSION: This study shows that resistant ascites can be initially mobilized by infusion of mannitol. The long-term benefits of such therapy are unknown.

Risk factors in young patients of acute myocardial infarction.

BACKGROUND: Ischemic heart disease is a leading cause of death throughout the world. CAD has been recognized among younger age group more frequently in recent years. Very limited data is available regarding the prevalence of various risk factors in our younger patients that is why this study was planed. Objectives of the study were to look for the risk factors most prevalent in our young patient of 1st Acute Myocardial Infarction. And to also look for the number of Risk Factors present in each patient. METHODS: We studied 100 consecutive patients from 16-45 years of age presenting with first acute MI. Twelve risk factors were studied namely, gender, family history of premature CAD, smoking hypertension, diabetes, dyslipidemia, obesity, mental stress (type A personality), alcohol, oral contraceptive pills (OCPs), physical activity, and diet. We divided the patients into two groups. Group A with patients 35 years of age or less and group B with patients 36-45 years of age. All risk factors were compared in both the groups. RESULTS: Smoking, diabetes mellitus, dyslipidemia and hypertension were statistically different between the two groups. Frequency wise risk factors were lined up as male sex (91%) Diet (66%), Dyslipidemia (62%), smoking (46%), Type A personality(46%), family history (32%), diabetes mellitus (28%), sedentary lifestyle (26%), hypertension (22%), obesity (17%), alcohol (3%), and OCPs (0%) Most of the patients that is 94% had 3 or more risk factors. CONCLUSION: Smoking, hypertension, diabetes and dyslipidemia are the major modifiable risk factors in our young adults. If a young male who is smoker or a young female who is diabetic, presents in emergency room with chest pain, always suspect coronary artery disease. Other conventional risk factors are also prevalent but alcohol and OCPs are not a major health problem for us.

Multiple dengue serotypes and high frequency of dengue hemorrhagic fever at two tertiary care hospitals in Lahore during the 2008 dengue virus outbreak in Punjab, Pakistan.

OBJECTIVE: The objective of this study was to investigate the clinical characteristics of patients with dengue viral infection during the 2008 outbreak in Lahore in order to better understand the clinical pattern and severity of disease in Lahore. METHODS: We analyzed the clinical characteristics of 110 patients infected with dengue virus; data were collected on standardized data collection sheets at two tertiary care hospitals from September to December 2008. Dengue infection was confirmed serologically or by real-time polymerase chain reaction (RT-PCR). RESULTS: Out of the total of 110 dengue infected patients, 70 were male and 40 were female. The most common symptoms included fever (100%), myalgia (68.2%), headache (55.5%), nausea (39.1%), skin rash (53.6%), mucocutaneous hemorrhagic manifestations (58.2%), and ocular pain (20%). Classic dengue fever (DF) was seen in 41.8% of the patients, 56.4% had dengue hemorrhagic fever (DHF), and only 1.8% developed dengue shock syndrome (DSS). The mean duration of fever was 6 days. Thrombocytopenia, leukopenia, and abnormal aspartate aminotransferase (AST)/alanine aminotransferase (ALT) were more frequently encountered in DHF and DSS as compared to DF. Viral RNA detection was done by RT-PCR in 17 patients. Ten patients had DEN4, five had DEN2, and two had DEN3 serotypes. The majority of the patients recovered completely without complications. CONCLUSION: The high frequency of DHF during the 2008 outbreak and the presence of three different dengue serotypes, emphasize the need to prevent and control dengue infection. Health authorities should consider strengthening surveillance for dengue infection, given the potential for future outbreaks with increased severity. It is also suggested that primary care physicians should be educated regarding recognition of DHF and to identify patients at high risk of developing DHF and DSS.
