Abstract
BACKGROUND Diabetes mellitus and central obesity are more common among South Asian populations than among White British people. This study explores the differences in diabetes and obesity in South Asians with stroke living in the United Kingdom, India, and Qatar compared with White British stroke patients. METHODS The study included the UK, Indian, and Qatari arms of the ongoing large Bio-Repository of DNA in Stroke (BRAINS) international prospective hospital-based study for South Asian stroke. BRAINS includes 4580 South Asian and White British recruits from UK, Indian, and Qatar sites with first-ever ischemic stroke. RESULTS The study population comprises 1751 White British (WB) UK residents, 1165 British South Asians (BSA), 1096 South Asians in India (ISA), and 568 South Asians in Qatar (QSA). ISA, BSA, and QSA South Asians suffered from higher prevalence of diabetes compared with WB by 14.5% (ISA: 95% confidence interval (CI) = 18.6-33.0, p < 0.001), 31.7% (BSA: 95% CI = 35.1-50.2, p < 0.001), and 32.7% (QSA: 95% CI = 28.1-37.3, p < 0.001), respectively. Although WB had the highest prevalence of body mass index (BMI) above 27 kg/m2 compared with South Asian patients (37% vs 21%, p < 0.001), South Asian patients had a higher waist circumference than WB (94.8 cm vs 90.8 cm, p < 0.001). Adjusting for traditional stroke risk factors, ISA, BSA, and QSA continued to display an increased risk of diabetes compared with WB by 3.28 (95% CI: 2.53-4.25, p < 0.001), 3.61 (95% CI: 2.90-4.51, p < 0.001), and 5.24 (95% CI: 3.93-7.00, p < 0.001), respectively. CONCLUSION South Asian ischemic stroke patients living in Britain and Qatar have a near 3.5-fold risk of diabetes compared with White British stroke patients. Their body composition may partly help explain that increased risk. These findings have important implications for public health policymakers in nations with large South Asian populations.

Cigarette smoking as a risk factor for ischaemic stroke in young South Asian male migrants to Qatar: The BRAINS study. Qatar Med J 2023; 2023:23. [PMID: 38089674 PMCID: PMC10714014 DOI: 10.5339/qmj.2023.23] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 07/30/2023] [Indexed: 05/08/2024] Open
Abstract
BACKGROUND The incidence of stroke in the Middle East is high, given its relatively young population. Smoking is a well-recognized risk factor for ischaemic stroke, and its high regional prevalence may partly account for this increased stroke risk. This research aims to determine whether young male South Asian migrants in Qatar were adversely affected by stroke depending on their smoking status. METHODS Data from the ongoing international prospective BRAINS study was analysed. Male South Asian migrants to Qatar with a history of ischaemic stroke were recruited. Multivariate regression analysis was used to estimate the effects of comorbidities, such as BMI, hypertension, diabetes, hypercholesterolemia, alcohol consumption, and ischemic heart disease, on the association of age of stroke onset and smoking status. RESULTS We identified 778 (mean age 49.5±10.2) migrant male workers of South Asian descent with ischaemic stroke in Qatar, of which 41.3% of the sample were current smokers. Compared to non-smokers, current smokers suffered a stroke 2.03 years earlier (95%CI: 0.60-3.46, P=0.005). Multivariate regression analysis demonstrated that only current smoking status was associated with an earlier age of stroke onset (β=2.03, SE=0.74, P=0.006). CONCLUSION Smoking is associated with at least a two-year earlier onset of ischaemic stroke in male South Asian migrants to the Middle East. Our study has important implications for the public health management of migrants in host countries.

Risk Factors, Clinical Presentation, Diagnosis, and Treatment Outcomes of Portal Vein Thrombosis: A Five-Year Hospital-Based Study From Qatar. J Clin Med Res 2022; 14:209-217. [PMID: 35720227 PMCID: PMC9187352 DOI: 10.14740/jocmr4718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 05/07/2022] [Indexed: 11/13/2022] Open
Abstract
Background There is a lack of robust epidemiological information on portal vein thrombosis (PVT) in Qatar. This study aimed to describe the risk factors, clinical presentation, diagnosis, and treatment outcomes of PVT in patients with and without liver cirrhosis admitted to Hamad General Hospital. Methods This retrospective observational study was conducted at Hamad General Hospital, Doha, Qatar. Consecutive patients with PVT between January 1, 2015 and December 31, 2019 were included in this study. Results We included 363 cases representing 0.05% of all inpatients admitted to our hospital during the study period. Their mean age was 47.79 ± 14.48 years. There were 258 (71.1%) males and 105 (28.9%) females. Abdominal pain was the most common presenting symptom (160 (44.1%)), while splenomegaly was the most common presenting sign (158 (43.5%)). Liver cirrhosis was the most frequent risk factor for PVT (147 (40.5%)), while no risk factors were identified in 49 (13.5%) patients. Anticoagulant therapy was given to 171/207 (82.6%) patients with acute PVT and 19/156 (12.2%) patients with chronic PVT. The options used for anticoagulation treatment were: low molecular weight heparin (LMWH) or unfractionated heparin alone, LMWH/unfractionated heparin followed by warfarin, and direct-acting oral anticoagulants (rivaroxaban). Out of the 262 patients in whom PVT recanalization was assessed, 43.8% of the cases had recanalization after anticoagulation treatment, while 12.6% of them had spontaneous recanalization without such therapy. A comparison between different anticoagulants used in this study showed no significant difference in the effectiveness of the three regimens used. The 30-day mortality was recorded for 71 patients (19.5%). The major risk factors for 30-day mortality were: age over 45 years, male sex, hepatic failure, malignancies, and bilirubin > 34 µmol/L. Conclusion PVT is a rare clinical entity in Qatar with liver cirrhosis being the most common risk factor. Early administration of anticoagulation therapy is associated with a significant recanalization, while age > 45 years, male sex, hepatic failure, malignancies, and bilirubin > 34 µmol/L are independent risk factors for 30-day mortality.

Abstract
BACKGROUND & OBJECTIVES Splenic abscess (SA) is a rare clinical entity. There is a lack of information on SA in most Arab and Gulf countries, including Qatar. This study describes the demographics, clinical features, microbiologic etiologies, treatments, and outcomes of patients with SA at the largest tertiary medical center in Qatar over the previous six years. METHODS This retrospective observational study was conducted at Hamad general hospital. It involved all patients of 18 years old or above who were admitted with the diagnosis of SA for the period between January 1, 2015, and December 31, 2020. RESULTS We recruited 25 patients, of which 14 (56%) were males, and 11 (44%) were females. The mean age ( ± SD) of them was 48.64 ± 19.08 years. The mean illness duration was 22.88 ± 11.88 days. Fever was the most common presenting symptom and was found in 21 (84%) cases, whereas bacteremia was the most predisposing factor found in 15 (60%) patients. The etiology of SA was bacterial in 16 cases (64%), mixed (fungal and bacterial) in one (4%), and tuberculous in one (4%), whereas the etiological agent was unidentified in seven (28%) cases. Intravenous antimicrobial therapy was administered empirically in all patients. However, seven patients (28%) received intravenous antibiotics as the only treatment modality for SA, 15 patients (60%) underwent percutaneous drainage with a pigtail catheter, and two patients underwent splenectomy. The inhospital mortality was three (12%). CONCLUSIONS This study showed that SA could be caused by various organisms that should be isolated to guide the choice of antimicrobial agents. An abdominal computed tomography is a good diagnostic modality, whereas computed tomography- and ultrasonography-guided percutaneous drainage were efficient therapeutic options that reduce the need for surgery.

Abstract
AbstractChronic kidney disease (CKD) is one of the most common disabling diseases globally. The main etiopathology of CKD is attributed to progressive renal fibrosis secondary to recurrent renal insults. Anemia is a known complication in CKD patients, associated with higher hospitalization rates and increased mortality risk. CKD-associated anemia (CKD-AA) is either due to true iron deficiency and/or functional iron deficiency anemia. There is new emerging evidence about the effects of erythropoiesis stimulating agents in the treatment of CKD-AA and their role in reversing and preventing kidney fibrosis in the early stages of CKD. This effect potentially provides new scopes in the prevention and treatment of CKD-AA and in decreasing the progression of CKD and the associated long-term complications. Epidemiology, pathophysiology, and treatments of CKD-AA will be discussed.

Association of vitamin B12 deficiency with metformin use in patients with type 2 diabetes treated in the largest tertiary care hospital in Qatar. Qatar Med J 2021; 2021:39. [PMID: 34540601 PMCID: PMC8428509 DOI: 10.5339/qmj.2021.39] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 05/24/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Data on the effect of metformin on serum vitamin B12 (VitB12) level in patients with type 2 diabetes mellitus (T2DM) in Qatar are limited; therefore, we aimed to assess the prevalence of VitB12 deficiency and its related factors among patients with tbl2DM treated with metformin at Hamad General Hospital in Doha, Qatar, from January 1, 2017, to December 31, 2017. METHODS This cross-sectional analytical study involved patients with tbl2DM aged ≥ 18 years who used metformin for at least 3 months. The serum VitB12 was quantified on a chemiluminescent enzyme immunoassay analyzer using Cobas e 801 module, Roche, and VitB12 deficiency was defined as serum VitB12 level of ≤ 145 pmol/L. All data were obtained from the patients' electronic medical records. RESULTS The study recruited 3124 eligible patients with tbl2DM. The overall prevalence of metformin-associated VitB12 deficiency was 30.7% [95% confidence of interval, 0.290-0.323]. A significant difference exists in the median VitB12 levels between the VitB12-normal and VitB12-deficient groups [129 vs. 286; p < 0.001]. Compared with the VitB12-normal group, the VitB12-deficient group had higher mean body mass index (BMI) (p < 0.001) and consumed higher doses of metformin (p = 0.001). They also more often used sulfonylurea (p = 0.004), dipeptidyl peptidase-4 inhibitor (p < 0.001), thiazolidinediones (p < 0.001), glucagon-like peptide 1 [GLP-1] receptor agonists (p < 0.001), alpha-glucosidase inhibitor (p < 0.001), and H2 blocker/proton pump inhibitors [PPI] (p < 0.001) than the VitB12-normal group. Moreover, the VitB12-normal group consumed more calcium supplements (p < 0.001) than the VitB12-deficient group. In the multivariate analysis, independent risk factors for metformin-associated VitB12 deficiency in patients with tbl2DM include high daily dose of metformin >2000 mg, male gender, high BMI, smoking, sulfonylurea, dipeptidyl peptidase-4 inhibitor, H2 blockers/PPI, low fasting blood glucose, and low hemoglobin. CONCLUSION This study showed a high prevalence of VitB12 deficiency in patients with tbl2DM taking metformin and a significant negative correlation between the daily dose of metformin and serum VitB12 level. Therefore, regular screening for serum VitB12 is necessary in patients with tbl2DM on metformin treatment, especially those who have the abovementioned risk factors.

Abstract
BACKGROUND: Reports on coronavirus disease 2019 (COVID-19) associated with acute pancreatitis continue to emerge. In this series, we present three cases of acute pancreatitis associated with COVID-19 with no obvious etiology.
CASE REPORTS: The first case was a 47-year-old man who presented with severe abdominal periumbilical pain, preceded by fever and dry cough. Based on a positive COVID-19 polymerase chain reaction (PCR) test and elevated serum amylase and lipase >3 times the upper normal limit, the diagnosis of COVID-19 and acute pancreatitis were established. The next case was a 57-year-old man with confirmed COVID-19 who developed severe epigastric pain radiating to the back and was associated with nausea and vomiting. His serum amylase and lipase were elevated >3 times the upper normal limit confirming the diagnosis of acute pancreatitis. The third case was a 31-year-old man who presented to the emergency department with a few hours of severe epigastric pain radiating to the back associated with nausea and vomiting. Two days before his presentation, he had a runny nose and fever. A combination of serum amylase and lipase elevation, >3 times the upper normal limits, and a positive COVID-19 PCR test were obtained concurrently, confirming the diagnosis of COVID-19 associated acute pancreatitis. All patients were admitted to the Mesaieed Hospital COVID-19 facility and received treatment for COVID-19 according to our local guidelines, while acute pancreatitis was treated conservatively. All three patients were discharged in good condition.
CONCLUSION: This case series suggests a possible correlation between COVID-19 and acute pancreatitis.

Abstract
We reported an anaphylactic reaction following ingestion of rivaroxaban in a 48-years-old male, who was recently discharged from the hospital as a case of deep vein thrombosis. At home, the patient developed a diffuse itchy skin rash, shortness of breath, and vomiting 30 minutes after rivaroxaban ingestion. Emergency Medical Service found that the patient had severe dyspnea, low blood pressure, and decreased blood oxygen saturation. The patient was given oxygen, intramuscular epinephrine, intravenous hydrocortisone, diphenhydramine, salbutamol nebulizer, and was immediately transferred to the emergency department of Hamad General Hospital. Subcutaneous enoxaparin was initiated, while hydrocortisone and salbutamol nebulizer continued. On the next day, his vital signs had stabilized, and intravenous hydrocortisone was switched to prednisolone tablets, and salbutamol nebulizer was switched to budesonide/salmeterol inhaler, whereas enoxaparin was overlapped with warfarin. After achieving the target international normalized ratio (INR), enoxaparin was discontinued and the patient was discharged with significant clinical and laboratory improvement.

Abstract
BACKGROUND several studies have been reported piperacillin-tazobactam (TAZ / PIPC)-associated AKI with various frequencies. The aim of this study was to determine the frequency of TAZ/PIPC- associated AKI among our patients and to identify the risk factors for this clinical entity. METHODS this retrospective cross-sectional study was conducted at Hamad General Hospital; it involved adult patients who were admitted from January 2017 to December 2017. RESULTS we involved 917 patients, of whom 635 (69.25%) were males and 282 (30.75%) were females. The mean age of the patients was 52 (SD 19) years, and 98 (10.7%) patients were diagnosed with AKI. The patients with AKI were significantly older than without AKI [59.71 (SD 19.79) versus 51.06 (SD 18.67); P <0.001]. After TAZ/PIPC initiation, the mean creatinine level in the AKI group was higher than the mean creatinine level in the non-AKI group, [158.91 (SD 81.93) versus 66.78 (SD 21.42); P<001]. The mean time of onset of AKI after PIPC/TAZ initiation was 4.46 (SD 3.20) (1-12 days). AKI was significantly associated with low mean serum albumin (P<0.001), high mean fasting blood glucose (P<0.001), coronary artery diseases (P<0.001), heart failure (P<0.001), liver diseases (P=0.047), diabetes mellitus (P=0.021) and hypertension (P<0.001). The in-hospital mortality was significantly higher in the AKI group [38.78% versus 5.13% in the non-AKI group; P<0.001], and only advanced age and heart failure were found as independent risk factors for TAZ/PIPC-associated AKI. CONCLUSION TAZ/PIPC was significantly associated with AKI. Advanced age and heart failure were identified as independent risk factors for TAZ/PIPC-associated AKI.

Abstract
Background & objectives: Enterococcal meningitis/ventriculitis (EMV) is a relatively rare condition that usually affects patients with underlying diseases. This study was designed to describe the clinical profile, laboratory parameters, treatment, and outcomes of EMV in patients admitted to Hamad General Hospital, Qatar. Methods and material: This retrospective hospital-based study described the patients with EMV from 2009 to 2013. Results: Eight patients were recruited for the study. Their median age was 42 years (21.50–53.75 years). Six patients (75%) were males, and two (25%) were females. Fever was the most common presenting symptom being present in seven (87.5%) cases. Six patients (75%) had nosocomial EMV, and all acquired the infection after placement of an external ventricular drain (EVD). The isolated species include seven (87.5%) E. faecalis and one (12.5%) E. gallinarum, and all of them were sensitive to ampicillin and vancomycin. In all patients with nosocomial EMV, the infected EVDs were removed, and the eight patients received empirical antibiotics that were modified upon receipt of culture results. All patients were cured, and no mortality was reported. Conclusions: EMV is a recognized complication related to the introduction of EVD, whereas community-acquired enterococcal meningitis was reported among children who had no established risk factors or immunosuppression. Because of its nonspecific clinical presentation, treating physicians should have a high suspicion index.

Abstract
The concomitant occurrence of tuberculous adenitis and Hodgkin lymphoma is rare, posing a diagnostic dilemma since both have similar symptoms, such as lymphadenopathy, weight loss, fever, and night sweats. We reported such a case in a 15-year-old girl who presented with fever and neck swelling and was found to have lymphadenopathy. A biopsy of the right supraclavicular lymph node showed Reed-Sternberg cells and stained positive for acid-fast bacilli and tuberculosis culture. The patient was diagnosed with tuberculous adenitis with concurrent Hodgkin lymphoma in the same lymph node. She was started on anti-tubercular medications and chemotherapy and showed clinical improvement. This case highlights the need for suspicion in order to identify these two disorders in the same patient, since missing one of them is possible and may lead to fatal complications.

Abstract
Objectives We sought to evaluate the role of bronchoscopy-related procedures such as bronchoalveolar lavage (BAL), bronchial wash (BW), bronchial brush (B brush), transbronchial biopsy (TBB), and post-bronchoscopy sputum (PBS), alone or in combination, in the rapid diagnosis of negative sputum smear disseminated tuberculosis (TB). Methods We performed a secondary post hoc analysis of data collected from our previous study entitled "Disseminated tuberculosis among adult patients admitted to Hamad General Hospital, Qatar: A five-year hospital-based study" with a modified objective. Results We identified 27 patients. BAL fluid was positive for acid-fast bacilli (AFB) smear in 7/27 (25.9%) patients and were culture-positive for Myobacterium tuberculosis in 17/27 (63.0%) cases, while BW collections were smear-positive in 9/27 (33.3%) cases and culture-positive for M. tuberculosis in 18/27 (66.7%) cases. TBB showed caseating granulomas in 10/16 (62.5%) cases and one case of non-caseating granuloma (6.3%). PBS was positive for AFB in 4/8 (50.0%) patients. The combination of these procedures enabled us to diagnose disseminated TB rapidly in 22 (81.5%) cases. Conclusions Bronchoscopy proved to be an effective method for the rapid diagnosis of disseminated TB in patients in whom sputum smear microscopy was negative.

Abstract
BACKGROUND The main purpose of this study was to describe the demographic and clinical features of cryptic disseminated TB; it was also aimed to shed light on diagnostic test, procedure results, organ involvement, and outcomes of cryptic disseminated TB in patients with confirmed disseminated TB. MATERIALS AND METHODS We performed a secondary post hoc analysis of collected data from our previous study entitled "Disseminated Tuberculosis among Adult Patients Admitted to Hamad General Hospital, Qatar: A Five-Year Hospital-Based Study" with modified objectives. This study included patients admitted from January 1, 2006 to December 31, 2010. RESULTS Twenty-three patients were recruited with non-miliary patterns on chest x-ray. Their mean age was 34.4±12.6 years and 15 (65.6%) were males. The mean duration of illness was 46.13±48.4 days and the most common presenting symptom was fever in 20 patients (87%), while 3 (13%) patients had underlying medical conditions with diabetes mellitus 2 (8.7%), being the most common. Bronchoalveolar lavage (BAL) and bronchial wash (BW) fluids were Acid-fast bacilli (AFB) positive in 1/4 (25%) of the cases and culture-positive for Mycobacterium tuberculosis (M. tuberculosis) in 4/4 (100%) of all the cases. Two patients (8.7%) had positive sputum smear, while 18 (78.3%) patients had positive culture for M. tuberculosis. All except one patient completed their treatment in Qatar. One patient died one month after the start of antituberculous treatment. CONCLUSION Cryptic disseminated TB should be suspected when a patient from TB-endemic countries develops unexplained fever and cough despite normal or non-miliary pattern chest radiograph. Moreover, respiratory specimen cultures should be obtained from these patients, regardless of the symptoms presented and the initial site of the involved organ.

Abstract
Objectives We sought to describe the epidemiological and clinical features of typhoid fever in Qatar. Methods We conducted a retrospective study of adult patients treated for typhoid fever at Hamad General Hospital and Alkhor Hospital between 2005 and 2012. Results The mean age of the 354 patients enrolled in the study was 28.4±9.3 years; 296 (83.6%) were males. There were 42, 48, 39, 44, 46, 47, 52, and 36 cases of adults with typhoid fever in 2005, 2006, 2007, 2008, 2009, 2010, 2011, and 2012, respectively. Overall, 343 (96.9%) patients had a history of travel to endemic areas. Among them, 93.0% acquired typhoid fever in the Indian subcontinent. Fever was observed in all cases, and the other predominant symptoms were abdominal pain (38.1%), diarrhea (35.6%), and headache (33.1%). Salmonella typhi, showed high resistance to ciprofloxacin (n = 163; 46.0%), and low resistance to ceftriaxone (n = 2; 0.6%). Four patients developed intestinal perforation, which was surgically repaired in two cases. Two patients (0.6%) died. Conclusions Typhoid fever was frequent among immigrants to endemic areas. Travelers returning from endemic areas with suspected typhoid fever should be treated empirically with third-generation cephalosporin after obtaining appropriate cultures. Moreover, preventive measurements such as education on food and water hygiene, and effective vaccination of travelers should be practiced widely among travelers to endemic areas to reduce morbidity and mortality.

Abstract
BACKGROUND/AIMS Acute pancreatitis (AP) is one of the most common gastrointestinal causes of hospital admission in Qatar. The aim of the present study was to investigate the epidemiological features and demographic characteristics of patients with AP and to estimate the annual incidence rates of this disease among adult inhabitants in Qatar. MATERIALS AND METHODS This retrospective study was conducted using the data collected by reviewing records of patients with AP admitted to the medical and surgical wards of Hamad GeneralHospital and Alkhor Hospital, Qatar from January 2007 to December 2012. Diagnosis of AP was based on abdominal pain suggestive of AP, serum lipase and/or amylase at least three times the upper limit of normal, and/or characteristic findings of AP on abdominal ultrasound or computed tomography. RESULTS A total of 382 AP events were reported in 334 patients. There were 250 (75%) males and 84 (25%) females. The mean age (±SD) of the patients was 56.8±18.7 years. Gallstone disease (40.6%) was the highest cause of AP, followed by alcohol consumption (28.5%) and idiopathic AP (20.7%). The mean annual incidence rate of AP was 5 per 100,000 adult inhabitants in Qatar from January 2007 to December 2012. The incidence rate among men was higher than that among women. Mortality rate was low (0.3%), and there were complications in 112 (29.3%) patients. CONCLUSION The annual incidence rate of AP is relatively low in Qatar and tends to behave similar to many European countries in etiology, which can be explained by population structure. Gallstone and alcohol consumption are the main causes, and idiopathic AP is responsible for more cases than expected.

Abstract
We report a case of Pseudomonas putida meningitis in a 26-year-old Nepalese man who was admitted to Hamad General Hospital with epidermoid cyst for drainage. Ommaya reservoir was placed into the cyst for drainage and externalventricular drainage (EVD) was performed. After four days, the patient was transferred to the ward in stable condition. His weakness resolved partially and headache severity decreased. After three days, the patient developed fever and headache severity increased with deterioration of consciousness level. Cerebrospinal fluid (CSF) through EVD showed 2 200 leucocytes/µL, protein level of 295 mg/dL, and glucose level of < 1.8 mg/dL. Meropenem was started on the patient. Aspirate from Ommaya reservoir and CSF showed gram-negative rods and cultures yielded P. putida sensitive to cefepime, gentamycin, ciprofloxacin, and amikacin, but resistant to meropenem and piperacillin-tazobactam. EVD was replaced and the patient received cefepime and ciprofloxacin for 21 days after which he improved and was discharged with right sided residual weakness.

Abstract
This retrospective study was conducted at Hamad General Hospital, Qatar, to describe the demographic data, clinical features underlying diseases, antimicrobial susceptibility, and outcome of A. baumannii infection. It involved all adult patients 15 years of age or older who were managed at Hamad General Hospital for A. baumannii infection from January 1, 2012, to December 31, 2013. We identified a total of 239 patients with A. baumannii infection, of which 182 (76.2%) were males. The mean age was 49.10 ± 19.57 years. The majority of the episodes (25.1%) occurred in elderly patients (≥65 years) and the most commonly identified site of A. baumannii infection was the respiratory tract, 117 (48.9%). Most episodes of infection, 231 (96.7%), were hospital-acquired and high rate of nosocomial infections occurred in the medical intensive care unit, 66 (28.6%). All patients had underlying medical conditions. Maximum resistance was seen to cefotaxime, 147 (58.3%), and minimum resistance was seen to colistin, 2 (1.4%). Of the 239 isolates, 102 (42.7%) were susceptible and 137 (57.3%) were multidrug-resistant. The in-hospital mortality in our study was 31%. Male gender, multidrug resistance, and septic shock were found to be independent mortality predictors.

Abstract
OBJECTIVE To describe the clinical presentation, underlying diseases, antimicrobial susceptibility, treatment and outcome of Klebsiella pneumoniae meningitis patients. METHODS This retrospective study involved all patients with 15 years of age or older who admitted to Hamad General Hospital with culture proven Klebsiella pneumoniae meningitis from January 1, 2007 to December 31, 2012. RESULTS A total of ten cases were identified (nine males and one female). Their mean age was (43.3±12.8) years. Eight patients (80%) had nosocomial meningitis with neurosurgery being the most frequent associated condition. Fever and altered consciousness were the most frequent symptom. Cerebrospinal fluid showed elevated protein and glucose levels. Gram stain showed Gram-negative rods in 50% of cases, while positive cerebrospinal fluid culture results were found in all patients. Multidrug resistance was observed in two cases, and all patients had received appropriate empirical and definitive antibiotic treatments. The mean duration of intravenous antimicrobial treatment was (19.3±7.0) d and all patients with external ventricular drains underwent removal of the device, while in-hospital mortality was 50%. CONCLUSIONS The number of cases was too small to come up with therapeutic and prognostic conclusions. Further large-scale prospective study is needed.

Abstract
OBJECTIVE To describe the etiology, clinical presentation, management and outcome of liver abscess in adult patients admitted at Hamad general hospital, Qatar. METHODS A cross sectional study was conducted to involve all adult patients who sequentially encountered episodes of liver abscess during the period from January 1, 2009, to December 31, 2010. Blood cultures were drawn from all patients in the first 24 hours after admission. In addition, all patients had stool examinations and indirect Hemagglutination test for Entameba histolytica. Aspiration of abscess was done under CT guidance and aspirated pus was sent for gram stain and culture. RESULTS In total, 67 patients were admitted with liver abscess; 56 patients with pyogenic liver abscess and 11 with amebic liver abscess. There were 61 (91%) males and six (9%) females and their mean age was 47.4 ± 18.5 years. Fever, abdominal pain and vomiting were the commonest presenting features. Of the 56 pyogenic liver abscess patients, four discharged against medical advice and seven refused all invasive procedures and were treated with antibiotics for six weeks. The remaining 44 (79%) patients were treated with antibiotics and one or more invasive procedures, while one patient was treated surgically. The commonest organism isolated was Klebseilla pneumonia found in 21 patients (38%). The mean duration of hospitalization was 13.6 ± 8.1 days; the mean duration of antibiotic therapy was 34.7 ± 40.6 days, and one patient died. In contrast, all amebic liver abscess patients underwent ultrasound guided aspiration and showed good response to metronidazole treatment. Their mean duration of hospitalization was 7.7 ± 4.1 days, mean duration of therapy was 11.8 ± 2.1 days, and all patients were cured. CONCLUSION Pyogenic liver abscess was more common than amebic liver abscess with Klebseilla pneumonia being the commonest organism. With good medical measures and early drainage of liver abscess, surgical intervention was unnecessary in almost all the cases.

Abstract
We report a case of ischaemic hepatitis associated with recurrent fast atrial fibrillation (AF) episodes in a 59-year-old male who presented with shortness of breath, nausea and vomiting. The patient had a history of ischaemic cardiomyopathy. An emergency electrocardiogram showed fast AF with a ventricular rate of 190 min(-1). The aspartate aminotransferase (AST) level was 2222Ul(-1), alanine aminotransferase (ALT) was 1255Ul(-1), lactate dehydrogenase (LDH) was 1842Ul(-1) and serum creatinine was 150 μmoll(-1). An ultrasound of the abdomen showed an enlarged liver with hypoechoic lesions. The patient received digoxin. In the next few days, while liver enzymes and serum creatinine started to return to normal levels, the patient had two attacks of fast AF, each associated with elevated liver enzymes and a concomitant rise in serum creatinine. The patient was transferred to the intensive care unit to improve control of his AF, after which his liver enzymes and renal function gradually returned to normal.

Abstract
We report four cases of nosocomial E. coli meningitis, in male patients with accidental and neurosurgical trauma. The interval between accidents/neurosurgical procedures and the onset of meningitis was 2-15 days (mean 6.25 days). The most consistent clinical features were fever and deterioration of consciousness level. Emergence of extended spectrum beta lactamase E. coli strains had been observed in two (50%) of our cases and the mean duration of antimicrobial treatment was 16.5 days (range: 6-24 days). Two of the four patients (50%) died in the hospital.

Abstract
Rhabdomyolysis, literally meaning the breakdown of muscle tissue, is a common syndrome with many causes, acquired ones such as exertion, trauma, infections, temperature extremes, drugs, toxins, electrolyte and endocrine abnormalities, and congenital ones such as myopathies and connective tissue disorders. All results in a common pathophysiologic pathway which ends with the dispersing of muscle tissue content into the circulation. Rhabdomyolysis has characteristic clinical, laboratory and radiologic features, but does require a high index of suspicion so that the diagnosis would not be missed. The sensitivity and specificity of the various characteristics, as well as clinical guidelines, are discussed in this paper. The syndrome may present with several complications, e.g. arrhythmias, electrolyte abnormalities, acute renal injury, acidosis, volume depletion, compartment syndrome and disseminated intravascular coagulation. The prognosis is highly variable and depends on the underlying etiologies and complications, but is in general considered as good. The milestone of treatment is vigorous fluid resuscitation. Treatment options, in practice and in research, are discussed in the following pages.

Abstract
We report isoniazid (INH)-induced encephalopathy in two male patients on hemodialysis. One of them had tuberculous adenitis, and the other had pulmonary tuberculosis. Both were given rifampicin, INH, pyrazinamide, and ethambutol with pyridoxine 40 mg/day. Two patients developed disturbances in consciousness. After excluding other causes, INH-induced encephalopathy was suspected so the drug was stopped and dose of pyridoxine increased. Both patients retained their consciousness within 1 week and were discharged.
