Demographic characteristics, laboratory features and complications in 346 cases of brucellosis: A retrospective study from Qatar.

Objectives: To study the epidemiology and laboratory findings and outcomes of human brucellosis in the state of Qatar. Methods: A retrospective study involving adult patients with a definitive diagnosis of brucellosis was conducted. Results: Of the 346 patients 299 were males. The mean age was 39.62 years. 120 patients had history of drinking raw milk and 116 had a history of contact with animals. Fever (89.9%) and myalgia (56.6%) were the most common presenting symptoms observed. Raised C-reactive protein level was the most frequent laboratory finding noted. Alanine aminotransferase and aspartate aminotransferase levels were raised to three times the normal in 39.6% and 37% of patients, respectively. Blood culture was positive in 72.8% whereas Brucella immunoglobulin G antibody and immunoglobulin M antibody titer was positive in 72.5% and 73.1% patients, respectively. Approximately 21.4% had focal involvement and osteoarticular (11.6%) involvement was the most frequently observed focal form. Doxycycline with rifampicin or gentamicin was the common regimen received. Relapse was seen in 7.2% patients. Conclusion: Human brucellosis continues to be a serious health issue in Qatar predominantly affecting healthy young adult men resulting in significant morbidity. Preventive measures and community awareness particularly among high-risk groups will help in decreasing the prevalence of the disease and its aftereffects.

Medical Admission Prediction Score (MAPS); a simple tool to predict medical admissions in the emergency department.

INTRODUCTION: Overcrowding in the emergency departments (ED) is linked to adverse clinical outcomes, a negative impact on patient safety, patient satisfaction, and physician efficiency. We aimed to design a medical admission prediction scoring system based on readily available clinical data during ED presentation. METHODS: In this retrospective cross-sectional study, data on ED presentations and medical admissions were extracted from the Emergency and Internal Medicine departments of a tertiary care facility in Qatar. Primary outcome was medical admission. RESULTS: Of 320299 ED presentations, 218772 were males (68.3%). A total of 11847 (3.7%) medical admissions occurred. Most patients were Asians (53.7%), followed by Arabs (38.7%). Patients who got admitted were older than those who did not (p <0.001). Admitted patients were predominantly males (56.8%), had a higher number of comorbid conditions and a higher frequency of recent discharge (within the last 30 days) (p <0.001). Age > 60 years, female gender, discharge within the last 30 days, and worse vital signs at presentations were independently associated with higher odds of admission (p<0.001). These factors generated the scoring system with a cut-off of >17, area under the curve (AUC) 0.831 (95% CI 0.827-0.836), and a predictive accuracy of 83.3% (95% CI 83.2-83.4). The model had a sensitivity of 69.1% (95% CI 68.2-69.9), specificity was 83.9% (95% CI 83.7-84.0), positive predictive value (PPV) 14.2% (95% CI 13.8-14.4), negative predictive value (NPV) 98.6% (95% CI 98.5-98.7) and positive likelihood ratio (LR+) 4.28% (95% CI 4.27-4.28). CONCLUSION: Medical admission prediction scoring system can be reliably applied to the regional population to predict medical admissions and may have better generalizability to other parts of the world owing to the diverse patient population in Qatar.

Differential evolution of diabetic ketoacidosis in adults with pre-existent versus newly diagnosed type 1 and type 2 diabetes mellitus.

BACKGROUND: Diabetic ketoacidosis (DKA) was once known to be specific to type-1 diabetes-mellitus (T1D); however, many cases are now seen in patients with type-2 diabetes-mellitus (T2D). Little is known about how this etiology shift affects DKA's outcomes. METHODS: We studied consecutive index DKA admissions from January 2015 to March 2021. Descriptive analyses were performed based on pre-existing T1D and T2D (PT1D and PT2D, respectively) and newly diagnosed T1D and T2D (NT1D and NT2D, respectively). RESULTS: Of the 922 patients, 480 (52%) had T1D, of which 69% had PT1D and 31% NT1D, whereas 442 (48%) had T2D, of which 60% had PT2D and 40% NT2D. The mean age was highest in PT2D (47.6 ± 13.1 years) and lowest in PT1D (27.3 ± 0.5 years) (P < 0.001). Patients in all groups were predominantly male except in the PT1D group (55% females) (P < 0.001). Most patients were Arabic (76% in PT1D, 51.4% in NT1D, 46.6% in PT2D) except for NT2D, which mainly comprised Asians (53%) (P < 0.001). Patients with NT2D had the longest hospital length of stay (LOS) (6.8 ± 11.3 days) (P < 0.001), longest DKA duration (26.6 ± 21.1 h) (P < 0.001), and more intensive-care unit (ICU) admissions (31.2%) (P < 0.001). Patients with PT1D had the shortest LOS (2.5 ± 3.5 days) (P < 0.001), DKA duration (18.9 ± 4.2 h) (P < 0.001), and lowest ICU admissions (16.6%) (P < 0.001). CONCLUSIONS/INTERPRETATION: We presented the largest regional data on differences in DKA based on the type and duration of diabetes- mellitus (DM), showing that T2D is becoming an increasing cause of DKA, with worse clinical outcomes (especially newly diagnosed T2D) compared to T1D.

Clinical and biochemical predictors of intensive care unit admission among patients with diabetic ketoacidosis.

BACKGROUND: Diabetic ketoacidosis (DKA) contributes to 94% of diabetes-related hospital admissions, and its incidence is rising. Due to the complexity of its management and the need for rigorous monitoring, many DKA patients are managed in the intensive care unit (ICU). However, studies comparing DKA patients managed in ICU to non-ICU settings show an increase in healthcare costs without significantly affecting patient outcomes. It is, therefore, essential to identify suitable candidates for ICU care in DKA patients. AIM: To evaluate factors that predict the requirement for ICU care in DKA patients. METHODS: This retrospective study included consecutive patients with index DKA episodes who presented to the emergency department of four general hospitals of Hamad Medical Corporation, Doha, Qatar, between January 2015 and March 2021. All adult patients (> 14 years) fulfilling the American Diabetes Association criteria for DKA diagnosis were included. RESULTS: We included 922 patients with DKA in the final analysis, of which 229 (25%) were managed in the ICU. Compared to non-ICU patients, patients admitted to ICU were older [mean (SD) age of 40.4 ± 13.7 years vs 34.5 ± 14.6 years; P < 0.001], had a higher body mass index [median (IQR) of 24.6 (21.5-28.4) kg/m2 vs 23.7 (20.3-27.9) kg/m2; P < 0.030], had T2DM (61.6%) and were predominantly males (69% vs 31%; P < 0.020). ICU patients had a higher white blood cell count [median (IQR) of 15.1 (10.2-21.2) × 103/uL vs 11.2 (7.9-15.7) × 103/uL, P < 0.001], urea [median (IQR) of 6.5 (4.6-10.3) mmol/L vs 5.6 (4.0-8.0) mmol/L; P < 0.001], creatinine [median (IQR) of 99 (75-144) mmol/L vs 82 (63-144) mmol/L; P < 0.001], C-reactive protein [median (IQR) of 27 (9-83) mg/L vs 14 (5-33) mg/L; P < 0.001] and anion gap [median (IQR) of 24.0 (19.2-29.0) mEq/L vs 22 (17-27) mEq/L; P < 0.001]; while a lower venous pH [mean (SD) of 7.10 ± 0.15 vs 7.20 ± 0.13; P < 0.001] and bicarbonate level [mean (SD) of 9.2 ± 4.1 mmol/L vs 11.6 ± 4.3 mmol/L; P < 0.001] at admission than those not requiring ICU management of DKA (P < 0.001). Patients in the ICU group had a longer LOS [median (IQR) of 4.2 (2.7-7.1) d vs 2.0 (1.0-3.9) d; P < 0.001] and DKA duration [median (IQR) of 24 (13-37) h vs 15 (19-24) h, P < 0.001] than those not requiring ICU admission. In the multivariate logistic regression analysis model, age, Asian ethnicity, concurrent coronavirus disease 2019 (COVID-19) infection, DKA severity, DKA trigger, and NSTEMI were the main predicting factors for ICU admission. CONCLUSION: In the largest tertiary center in Qatar, 25% of all DKA patients required ICU admission. Older age, T2DM, newly onset DM, an infectious trigger of DKA, moderate-severe DKA, concurrent NSTEMI, and COVID-19 infection are some factors that predict ICU requirement in a DKA patient.

A retrospective study on comparison of clinical characteristics and outcomes of diabetic ketoacidosis patients with and without acute pancreatitis.

The co-existence of diabetic ketoacidosis (DKA) with acute pancreatitis (AP) is associated with unfavorable clinical outcomes. However, diagnosing AP in DKA patients is challenging and often missed due to overlapping symptoms. The aim of this retrospective observational study was to compare the clinical characteristics and outcomes of patients with concomitant DKA and AP or DKA alone. Data of patients with DKA admitted between January 2015 to August 2021 to four hospitals in Qatar was extracted from the electronic health record (Cerner). American Diabetes Association criteria and Atlanta criteria were used for DKA and AP diagnosis, respectively. Independent T-test or Mann-Whitney U test was used to analyze continuous variables, whereas categorical variables were analyzed via Chi-square or Fischer exact tests as appropriate. Univariate and multivariate logistic regression models were generated to assess the correlations. A p-value of < 0.05 was considered statistically significant. Of 936 patients with DKA, 84 (9.0%) had coexisting AP. AP was most common in the Asian race (66%, p < 0.001). Patients with DKA and AP were older, had higher admission anion-gap, white cell count, hemoglobin (hb), neutrophil/lymphocyte ratio, urea, creatinine, maximum blood glucose during the episode, total cholesterol and triglyceride level (TGL) (p < 0.05). They had a lower admission venous pH and bicarbonate at 6 h. Patients in the DKA with AP group also had a longer length of stay (LOS), DKA duration and a higher rate of ICU admission (p-values ≤ 0.001). In-hospital mortality, 3-month all-cause readmission, 6-month and 12-month DKA recurrence did not differ between the two groups. Univariate logistic regression analysis showed age, Asian ethnicity, male gender, T2D, admission WBC count, hb, urea, creatinine, potassium, venous pH, bicarbonate, anion gap, total cholesterol, TGL and LDL level were significantly associated with the development of DKA with AP (p < 0.05). In multivariate logistic regression analysis, age and total cholesterol level were associated with concomitant DKA and AP (p < 0.05). Patients with concomitant DKA and AP have more severe derangement in markers of DKA severity, inflammation, kidney injury and metabolic profile, along with a longer DKA duration, LOS and requirement for ICU support compared to DKA patients without AP. This highlights the clinical significance of diagnosing the co-existence of DKA with AP, as the combination results in significantly worse clinical outcomes and greater healthcare utilization than in patients with only DKA.

Clinical and biochemical determinants of length of stay, readmission and recurrence in patients admitted with diabetic ketoacidosis.

BACKGROUND: The increasing prevalence of diabetic ketoacidosis (DKA) related admissions poses a significant burden on the healthcare systems globally. However, data regarding the predictors of healthcare resource utilization in DKA is limited and inconsistent. This study aimed to identify key predictors of hospital length of stay (LOS), readmission and recurrent DKA episodes. METHODS: We undertook a retrospective cross-sectional analysis of all DKA admissions from 2015 to 2021 across four hospitals in Qatar. The primary outcomes were the length of stay (LOS), 90-day readmission and 6-month and 1-year DKA recurrence. RESULTS: We included 922 patients with a median age of 35 years (25-45). 62% were males with type-1 diabetes-mellitus (T1DM) and type-2 DM (T2DM), present in 52% and 48% of patients. The median LOS was 2.6 days (IQR 1.1-4.8), and the median DKA resolution time was 18 h (10.5-29). Male-gender, new-onset DM, higher Charlson Comorbidity Index (CCI), lower haemoglobin, sodium and potassium, higher urea, longer DKA duration and MICU admission predicted a longer LOS in a multivariate regression analysis. None of the factors were significantly associated with 90-day readmission. Patients with pre-existing T1DM were more likely to have a six-month DKA recurrence than pre-existing T2DM. Patients with a 6-month DKA recurrence, female gender and T1DM had higher odds of 12-month recurrence, whereas a consult with a diabetes educator at the index admission was associated with decreased odds of recurrence. CONCLUSIONS/INTERPRETATION: This is the most extensive study from the Middle-East region reporting on LOS, readmissions and the recurrence of DKA. Results from this study with a diverse population may be valuable for physicians and healthcare systems to decrease the diabetes-related healthcare burden in DKA patients.

Comparison of demographic, clinical and laboratory characteristics between first and second COVID-19 waves in a secondary care hospital in Qatar: a retrospective study.

OBJECTIVE: To compare the patient profile and outcomes in Qatar during the first and second waves of the COVID-19 pandemic. SETTING: A retrospective observational study was conducted comparing the demographic, clinical and laboratory characteristics of patients with COVID-19 infection admitted to a secondary care hospital, during the first and second waves of the pandemic. PARTICIPANTS: 1039 patients from the first wave and 991 from the second wave who had pneumonia on chest X-ray and had a confirmed SARS-CoV-2 infection by a real-time PCR test of a nasopharyngeal swab were included. Patients with a normal chest X-ray and those who had a negative PCR test despite a positive COVID-19 antigen test were excluded. OUTCOME: Length of stay, need for mechanical ventilation, final disposition and mortality were the key outcomes studied RESULTS: Influenza like symptoms (18.5% in the first wave vs 36.1% in the second wave, p 0.001), cough (79.2% vs 87%, p<0.001) and dyspnoea (27.5% vs 38% p<0.001) were more common in the second wave. Second wave patients had significantly higher respiratory rate, lower peripheral oxygen saturation, needed more supplemental oxygen and had higher incidence of pulmonary embolism. More patients received hydroxychloroquine and antibiotics during the first wave and more received steroids, antivirals and interleukin-1 antagonist during the second wave. The second wave had a shorter length of stay (14.58±7.75 vs 12.61±6.16, p<0.001) and more patients were discharged home (22% vs 10%, p<0.001). CONCLUSIONS: Patients who presented during the second wave of COVID-19 pandemic appeared to be more ill clinically and based on their laboratory parameters. They required shorter hospitalisation and were more likely to be discharged home. This could represent greater expertise in handling such patients that was acquired during the first wave as well as use of more appropriate and combination therapies during the second wave.

Artesunate-induced hemolysis in severe complicated malaria - A diagnostic challenge: A case report and literature review of anemia in malaria.

Malaria infection, which results due to the parasitic protozoan Plasmodium, has several known etiologies of hemolytic anemia as a possible complication in cases such as concurrent G6PD deficiency, severe parasitemia, or use of parenteral antimalarials. Although artemisinin-based antimalarial therapies are generally well-tolerated, several cases of severe post-artemisinin delayed hemolysis (PADH) have been recently reported, which present a diagnostic challenge, and affect morbidity and mortality in patients with malarial infection. We highlight the case of a young lady with Plasmodium falciparum severe parasitemia who developed hemolytic anemia after parenteral artesunate therapy.

Autoimmune hemolytic anemia associated with vitamin B12 deficiency and viral illness in DiGeorge syndrome. Case report and literature review.

Vitamin B12 plays a crucial role in cell maturation and differentiation. Its deficiency can lead to cytopenias and even hemolysis. We suggest regular monitoring and maintenance of Vit B12 levels in DiGeorge syndrome patients to prevent such triggers.

Breast Cancer Screening Practices in a Tertiary Care Center in the State of Qatar: A Cross-Sectional Survey.

INTRODUCTION: Breast cancer is the most common cancer in females. In Qatar, mortality related to breast cancer came in third after lung cancer and leukemia. In this study, we aim to comprehensively evaluate the rate of internal medicine residents and faculty compliance with breast cancer screening in Hamad Medical Corporation (Doha, Qatar), as well as to identify barriers and facilitators that could potentially augment changes to enhance physician-led cancer screening. METHODS: A cross-sectional web-based survey was distributed among internal medicine physicians between December 2018 and March 2019 at a tertiary medical centre. It focused on the knowledge, attitude, and practice of physicians regarding breast cancer screening guidelines and explored potential barriers and proposed solutions. Chi-square and t-test statistics were used to draw conclusions where appropriate. RESULTS: A total of 158 physicians responded to the survey, with a response rate of 61%. 75.9% were postgraduate trainees. Around three-quarters of the physicians mentioned that they would recommend breast cancer screening for their age-appropriate average-risk patients. There was a statistically significant difference between the trainees, consultants, and specialists regarding the modality of choice, where the majority of the trainees opted mammogram every 2 or 3 years while 44.4% of the consultants indicated yearly self-breast exam (p<0.001). The percentage of survey participants who rarely to never offer breast cancer screening in the outpatient settings was 37.8%. Unclear pathway (40%) and lack of time in clinic/ward rounds (26.5%) were the major reported barriers for cancer screening. CONCLUSION: In the current era of personalized medicine, physicians should be more oriented to local guidelines to provide optimal care to their patients. While the attitude towards breast cancer screening is positive, the overall compliance with the national recommendations is sub-optimal. Further initiatives and intervention programs are required to promote the breast cancer screening in Qatar.

Impact of COVID-19 upon changes in emergency room visits with chest pain of possible cardiac origin.

OBJECTIVES: A decrease in Emergency Department (ED) visits for cardiac conditions has recently been reported from the US and Western Europe due to the COVID-19 pandemic. The data are still scant, and the correlation between cardiac symptoms and confirmed diagnoses are not available. There are no reports on changes in ED volumes at a national level, or from countries in the Asia-Middle Eastern region. We report data from national referral centers for tertiary care and cardiac care centers in Qatar, which see > 80% of cardiac emergencies in the country. RESULTS: We analyzed 102,033 ED visits in the COVID-19-era (March-April 2020 and 2019) and determined the proportion presenting for cardiac symptoms and their confirmed diagnoses. We observed a 16-37% decline in ED volumes overall, with a 25-50% decline in patients presenting with cardiac symptoms in March and April 2020 compared with March and April 2019. Among those presenting with cardiac symptoms, we observed a 24-43% decline in cardiac diagnoses in March and April 2020 compared with March and April 2019.

Optic neuropathy as a presenting feature of vitamin B-12 deficiency: A systematic review of literature and a case report.

INTRODUCTION: Vitamin B12 (VitB12) deficiency rarely manifests with visual symptoms. Optic nerve damage in VitB12 deficiency is thought to be via degeneration. However, optic neuritis, though infrequent, has been reported secondary to VitB12 deficiency. MATERIAL AND METHODS: We conducted a systematic review of all the reported cases of VitB12 deficiency with optic nerve involvement in Pubmed, Cochrane, and Google Scholar any date up to September 6, 2020. We have discussed the findings and compiled the available information on ophthalmological manifestations of VitB12 deficiency. We aim to provide a unified knowledge about the evidence related to types of optic neuropathies reported to date secondary to VitB12 deficiency. We also present a case of bilateral optic neuritis secondary to VitB12 deficiency. PRESENTATION OF CASE: We present a 29-year-old previously healthy male with progressive, painful, bilateral, but asymmetric visual deterioration for forty-five days. A detailed history, examination, and laboratory workup were carried out. He was diagnosed as having optic neuritis secondary to VitB12 deficiency. He showed partial improvement with the replacement of VitB12. CONCLUSION: We suggest promptly identifying and replacing VitB12 in patients with optic neuritis with proven VitB12 deficiency to prevent permanent damage to the optic nerve. Patients with VitB12 deficiency should have a baseline fundoscopic exam to rule out subclinical optic nerve damage. Moreover, patients who present with visual disturbances should be screened for VitB12 deficiency, especially the vegan population.

Knowledge, Attitude and Practice of Physicians Regarding Screening of Colorectal Cancer in Qatar: A Cross-Sectional Survey.

PURPOSE: The aim of this study was to evaluate the rate of internal medicine residents' and faculties' (specialists and consultants) compliance to colorectal cancer screening in Hamad Medical Corporation (Doha, Qatar) and to identify barriers as well as facilitators that will assist in drawing up changes that would enhance physician-related cancer screening. METHODS: A cross-sectional web-based survey was distributed among internal medicine physicians at three component hospitals of Hamad Medical Corporation (HMC); focusing on knowledge and practice of colorectal cancer screening, its barriers and facilitators. Chi-square and t-test statistics were used to draw conclusions where appropriate. RESULTS: The response rate for the survey was 91% and over 75% of the survey respondents were post-graduate trainees. The majority (90.6%) of the physicians (n=144) mentioned that they would recommend colorectal cancer screening for their asymptomatic patients, though trainees tend to choose the correct modality of screening compared to the consultants, 86.21% vs 40.74%. Only 43.4% of the survey participants always to usually recommend screening to their patients in their clinics while only 29.4% do so for their inpatients. Even though there was no statistically significant difference among the frequency of outpatient colorectal cancer screening among trainees, specialists or consultants (p=0.628), there was a clear increase in the reported referrals as the training years or the years of experience increases (p=0.049 for trainees and p=0.009 for faculty). Unclear pathway was reported as the main obstacle to outpatient cancer screening by 30.2% (n= 48) and 54% (n=87) pointed out that an easy and clear pathway for cancer screening would facilitate the same. CONCLUSION: While the attitude towards colorectal cancer screening is positive, the actual practice of recommendation is sub-optimal. Further initiatives are required to facilitate awareness and compliance to colorectal cancer screening.

Volume and Acuity of Emergency Department Visits Prior To and After COVID-19.

BACKGROUND: There are scant data regarding the change in volume and acuity of patients presenting to emergency departments (EDs) after Coronavirus Disease 2019 (COVID-19), compared with the pre-COVID-19 era. OBJECTIVE: To determine ED volumes and triage acuity prior to and after COVID-19. METHODS: We determined the volume of patients presenting to four large EDs affiliated with general, cardiac, cancer, and obstetrics hospitals, and the acuity of presenting illness (using the Canadian Triage Acuity Scale [CTAS]) for March and April 2020 and compared them with the same months in 2019 and January 2020. Together, these facilities see over 80% of the ED visits in Qatar. The first COVID-19 patient in Qatar was diagnosed on February 29, 2020. RESULTS: A total of 192,157 ED visits were recorded during the study period. There was a 20-43% overall drop in number of ED visits, with significant variability across hospitals. The Heart Hospital experienced the sharpest decline (33-89%), and the National Center for Cancer Care and Research experienced the least decline in volumes. The decline was observed across all CTAS levels, with the largest decline observed in individuals presenting with CTAS 1 and 2 (26-69% decline month by month). No increase in overall number of deaths or crude mortality rate was observed in the COVID-19 era, according to national statistics. CONCLUSIONS: Sharp declines in ED visits and the triage acuity seen in both general and specialty hospitals raise the concern that severely ill patients may not be seeking timely care, and a surge may be expected once current restrictions on movement are lifted.

Comparative effectiveness and safety of direct-acting oral anticoagulants (DOACS) for the reduction of recurrent venous thromboembolism in cancer patients: A protocol for systematic review and network meta-analysis using a generalized pairwise modeling methodology.

BACKGROUND: There has been a significant improvement in both our understanding and therapeutic choices available to clinicians for the management of cancer associated thrombosis (CAT). Even with the recent publication of a systematic review and landmark trials demonstrating the non-inferiority of DOACS-based anticoagulation strategy compared to the standard of care in patients with CAT, there is unresolved uncertainty regarding the exact hierarchy of risks and effectiveness of various DOAC analogues in these cohorts of patients. METHOD: We will carry out a network meta-analyses, utilizing a novel generalized pairwise methodology to generate direct and indirect comparisons between the various DOAC analogues. We will search the following databases for studies that satisfies pre-specified inclusions criteria; these include PubMed, EMBASE, Cochrane library, Clinicaltrials.gov, conference abstracts among other sources. The primary efficacy and safety outcomes are recurrent VTE and major hemorrhagic events, respectively. Two reviewers will Search the databases independently with the view to identify studies that meet eligibility criteria. The methodological quality of the included studies will be determined using a recently validated risk of bias assessment tool. RESULTS: We expect that the result of this review will ascertain the hierarchy of risks and effectiveness of various DOAC analogues in patients with CAT. CONCLUSION: Results of this review will assist in informed decisions making regarding therapeutic guidelines of DOAC in CAT.

Fungal Malignant Otitis Externa Involves a Cascade of Complications Culminating in Pseudoaneurysm of Internal Maxillary Artery: A Case Report.

BACKGROUND Pseudomonal infection is the most common cause of malignant otitis externa (MOE), which typically affects elderly diabetic patients. Fungi are a rare cause of MOE. MOE can be life-threatening if not recognized and treated promptly. It can result in a wide spectrum of complications, including skull-base osteomyelitis, cranial nerve palsy, cerebral venous thrombosis, and brain abscess. Pseudoaneurysm formation of the intracranial vessels is a life-threatening complication of MOE that is seldom reported in the literature. CASE REPORT We report the case of a 66-year-old diabetic man with MOE who was initially treated with antipseudomonal antibiotics after negative initial culture results. His MOE resulted in a cascade of complications, including facial nerve palsy, skull base osteomyelitis, and sigmoid sinus thrombosis, and culminated in left maxillary artery pseudoaneurysm formation resulting in massive epistaxis and hemodynamic instability. Endovascular embolization resulted in a successful obliteration of the pseudoaneurysm. A subsequent functional endoscopic sinus surgical (FESS) tissue biopsy confirmed Candida glabrata as the etiological agent. The patient was successfully treated with antibiotics and antifungal and anticoagulation therapy, and was discharged home in good condition. CONCLUSIONS A high index of suspicion for the diagnosis of fungal MOE, particularly in intractable cases of MOE with negative initial cultures, should be maintained. Pseudoaneurysm formation is a life-threatening complication of MOE that is seldom reported in the literature and should be suspected in any patient with MOE who presents with epistaxis or intracranial bleeding.

Portomesenteric Thrombosis Secondary to Acute Cholecystitis: A Case Report.

Portomesenteric venous thrombosis (PMVT) is an uncommon clinical problem. Common risk factors include intra-abdominal infections, abdominal surgeries, malignancy, cirrhosis, and inherited thrombophilia. Early recognition and treatment of PMVT are important to avoid serious complications like mesenteric ischemia and infarction. Acute cholecystitis is a clinical condition encountered daily but rarely may be complicated by development of portomesenteric venous thrombosis. Only few cases have been reported of superior mesenteric vein thrombosis secondary to cholecystitis. We report a case of a forty-one-year-old male patient who developed partial portal and superior mesenteric vein thrombosis after mild acute cholecystitis for which surgery had been deferred. Patient had no other identifiable risk factors for thrombosis. Patient was successfully treated with 6 months of anticoagulation with warfarin and complete recanalization of portomesenteric veins was achieved at the end of treatment.

Effects of procalcitonin-guided treatment on antibiotic use and need for mechanical ventilation in patients with acute asthma exacerbation: Meta-analysis of randomized controlled trials.

OBJECTIVE: The primary outcome was to determine whether serum procalcitonin-guided antibiotic therapy can reduce antibiotic exposure in patients with an acute exacerbation of asthma presenting to the primary care facility or emergency department, or during hospital admission. The secondary outcome was the need for mechanical ventilation. METHODS: An extensive literature search was performed to identify randomized controlled clinical trials (published in English) that compared serum procalcitonin-guided antibiotic therapy versus antibiotic use according to physician's discretion for adult participants with mild, moderate, or severe acute asthma exacerbations. RESULTS: Four randomized controlled trials evaluating 457 patients were included in this meta-analysis, with significant homogeneity observed among these studies. Procalcitonin-based protocols decreased antibiotic prescriptions (relative risk 0.58, 95% confidence interval 0.50-0.67). The conclusion regarding the difference between the two groups in the need for mechanical ventilation (relative risk 1.10, 95% confidence interval 0.62-1.94) was guarded due to inadequate power and the potential for type II error. The overall quality of evidence was also limited by the lack of double-blinding. CONCLUSIONS: These data suggest a potential benefit for the use of serum procalcitonin in guiding antibiotic therapy in patients with an acute asthma exacerbation and advocates the need for more randomized controlled trials.

Nurse practitioner and physician assistant scope of practice in 118 acute care hospitals.

BACKGROUND: Advanced practice providers (APPs), including nurse practitioners (NPs) and physician assistants (PAs) are cost-effective substitutes for physicians, with similar outcomes in primary care and surgery. However, little is understood about APP roles in inpatient medicine. OBJECTIVE: Describe APPs role in inpatient medicine. DESIGN: Observational cross-sectional cohort study. SETTING: One hundred twenty-four Veterans Health Administration (VHA) hospitals. PARTICIPANTS: Chiefs of medicine (COMs) and nurse managers. MEASUREMENTS: Surveys included inpatient medicine scope of practice for APPs and perceived healthcare quality. We conducted bivariate unadjusted and multivariable adjusted analyses. RESULTS: One hundred eighteen COMs (95.2%) and 198 nurse managers (75.0%) completed surveys. Of 118 medicine services, 56 (47.5%) employed APPs; 27 (48.2%) used NPs only, 15 (26.8%) PAs only, and 14 (25.0%) used both. Full-time equivalents for NPs was 0.5 to 7 (mean = 2.22) and PAs was 1 to 9 (mean = 2.23). Daily caseload was similar at 4 to 10 patients (mean = 6.5 patients). There were few significant differences between tasks. The presence of APPs was not associated with patient or nurse manager satisfaction. Presence of NPs was associated with greater overall inpatient and discharge coordination ratings by COMs and nurse managers, respectively; the presence of PAs was associated with lower overall inpatient coordination ratings by nurse managers. CONCLUSIONS: NPs and PAs work on half of VHA inpatient medicine services with broad, yet similar, scopes of practice. There were few differences between their roles and perceptions of care. Given their very different background, regulation, and reimbursement, this has implications for inpatient medicine services that plan to hire NPs or PAs.
