Infective endocarditis due to Bacillus cereus in a pregnant female: A case report and literature review.

Incidence of infective endocarditis during pregnancy is around 0.006% with high maternal and fetal mortality. Bacillus cereus is an extremely rare cause for endocarditis in intravenous drug abusers (IVDA) or those with valvular disease or devices such as pacemakers. We report a case of B. cereus endocarditis, which, to the best of our knowledge, has never been reported in pregnancy. A 30-year-old, 25-week pregnant female presented with right shoulder pain, swelling and erythema on the lateral aspect of deltoid muscle from large abscess over her deltoid muscle. She was found to have a vegetation on the native tricuspid valve. Cultures from abscess fluid and blood cultures grew B. cereus, she was appropriately treated with antimicrobials and had favorable outcomes. There are <20 cases of B. cereus endocarditis reported but none during pregnancy. When cultures grow unusual organisms the case must be thoroughly investigated. This case illustrates a rare situation (endocarditis in pregnancy) with an unusual outcome (B. cereus) on an uncommon valve (tricuspid valve).

Clinical utility of the HEART score in patients admitted with chest pain to an inner-city hospital in the USA

Background Chest pain is one of the most common presentations to a hospital, and appropriate triaging of these patients can be challenging. The HEART score has been used for such purposes in some countries and only a few validation studies from the USA are available. We aim to determine the utility of the HEART score in patients presenting with chest pain to an inner-city hospital in the USA. Patients and methods We retrospectively screened 417 consecutive patients admitted with chest pain to the observation/telemetry units at Einstein Medical Center Philadelphia. After applying inclusion and exclusion criteria, 299 patients were included in the analysis. Patients were divided into low-risk (0–3) and intermediate-high (≥4)-risk HEART score groups. Baseline characteristics, thrombolysis in myocardial infarction score, need for revascularization during index hospitalization, and major adverse cardiovascular events (MACE) at 6 weeks and 12 months were recorded. Results There were 98 and 201 patients in the low-score group and intermediate-high-score group, respectively. Compared with the low-score group, patients in the intermediate-high-risk group had a higher incidence of revascularization during the index hospital stay (16.4 vs. 0%; P=0.001), longer hospital stay, higher MACE at 6 weeks (9.5 vs. 0%) and 12 months (20.4 vs. 3.1%), and higher cardiac readmissions. HEART score of at least 4 independently predicted MACE at 12 months (odds ratio 7.456, 95% confidence interval: 2.175–25.56; P=0.001) after adjusting for other risk factors in regression analysis. Conclusion HEART score of at least 4 was predictive of worse outcomes in patients with chest pain in an inner-city USA hospital. If validated in multicenter prospective studies, the HEART score could potentially be useful in risk-stratifying patients presenting with chest pain in the USA and could impact clinical decision-making.

CLINICAL UTILITY OF HEART SCORE IN PATIENTS ADMITTED WITH CHEST PAIN TO AN INNER CITY HOSPITAL

Appropriate triage of patients with chest pain can be challenging. HEART score was proposed by Six et al in Netherlands to facilitate quick triage in emergency room. It is not validated in US. This pilot study was initiated to determine utility of HEART score in patients presenting with chest pain

Sinus venosus atrial septal defect presenting with brain abscesses in a 77-year-old immunocompetent patient.

We present a case of 77-year-old immunocompetent patient who initially presented with vertigo, nausea and vomiting, with symptoms later progressing to headaches and increased lethargy. Brain MRI revealed ring-enhancing lesions typical of abscesses in the right cerebellum. Transoesophageal echocardiogram (TEE) was performed to look for the source of his abscesses, and uncovered a sinus venosus type atrial septal defect. Cardiac CT was carried out; the patient was found to have a sinus venosus atrial septal defect with partial anomalous pulmonary venous return. Moreover, dental examination showed multiple dental caries with poor oral hygiene. The patient was started on intravenous empiric antibiotics and steroids. Subsequent brain imaging showed almost complete resolution of the abscesses. The patients symptoms started to improve, and he was eventually sent to an intensive rehabilitation centre with future plans to surgically correct his congenital heart disease to prevent further complications.
