Secondary left ventricular injury with haemopericardium caused by a rib fracture after blunt chest trauma

Trauma is the third most common cause of death in the West. In the US, approximately 90,000 deaths annually are traumatic in nature and over 75% of casualties from blunt trauma are due to chest injuries. Cardiac injuries from rib fractures following blunt trauma are extremely rare. We report the unusual case of a patient who fell from a height and presented with haemopericardium and haemothorax as a result of left ventricular and lingular lacerations and was sucessfully operated upon

Obstructive sleep apnea is underrecognized and underdiagnosed in patients undergoing bariatric surgery

The aim of this study was to evaluate prevalence of obstructive sleep apnea among patients undergoing bariatric surgery and the predictive value of various clinical parameters: body mass index (BMI), neck circumference (NC) and the Epworth Sleepiness Scale (ESS). We performed a prospective, multidisciplinary, single-center observational study including all patients on the waiting list for bariatric surgery between June 2009 and June 2010, irrespective of history or clinical findings. Patients visited our ENT outpatient clinic for patient history, ENT and general examination and underwent a full night polysomnography, unless performed previously. As much as 69.9% of the patients fulfilled the criteria for OSA (mean BMI 44.2 ± SD 6.4 kg/m2); 40.4% of the patients met the criteria for severe OSA. The regression models found BMI to be the best clinical predictor, while the ROC curve found the NC to be the most accurate predictor of the presence of OSA. The discrepancy of the results and the poor statistical power suggest that all three clinical parameters are inadequate predictors of OSA. In conclusion, in this large patient series, 69.9% of patients undergoing BS meet the criteria for OSA. More than 40% of these patients have severe OSA. A mere 13.3% of the patients were diagnosed with OSA before being placed on the waiting list for BS. On statistical analysis, increased neck circumference, BMI and the ESS were found to be insufficient predictors of the presence of OSA. Polysomnography is an essential component of the preoperative workup of patients undergoing BS. When OSA is found, specific perioperative measures are indicated

Intermittent intravalvar regurgitation of a mechanical aortic valve prosthesis Diagnosis and clinical implications A case report

Mechanical prosthetic valve regurgitation may be either periprosthetic or intraprosthetic. The later is usually mild, occurring in the majority of normally functioning valves and is due to the 'regurgitant flow' closing the valve. An unusual case is reported of intermitent intraprosthetic regurgitation through a normally functioning aortic Medtronic-Hall prosthesis caused by tissue ingrowth below the valve 4 years after implantation

Mechanisms and management of heart failure in active rheumatic carditis

Fulminating active rheumatic carditis has been observed for over three decades in this environment with no recent alteration in either the incidence or the pattern of presentation. Heart failure (in this context defined as 'an inadequate circulation at rest together with a raised pulmonary venous pressure, with or without an associated high systemic venous pressure in the absence of haemodynamically significant tricuspid valve disease or pericardial effusion') is prevalent but occurs only when a haemodynamically important leftsided valve lesion supervenes. Regurgitation is the predominant valve lesion and involves principally the mitral valve. Mitral annular dilatation is marked and predisposes to lengthening - or rupture - of chordae tendineae and prolapse of the anterior leaflet. The resultant cardiac workoverload apparently perpetuates or aggravates the rheumatic activity. Heart failure, as defined, whether caused by or associated with active rheumatic carditis, makes surgical management of the valve lesion mandatory as a life-saving measure. Aggressive medical therapy for heart failure, which should include vasodilator drugs and especially angiotensinconverting enzyme inhibitors, provides temporary improvement only. Contrary to ongoing doctrine, treatment with steroid drugs in this context is neither life-saving nor beneficial

Distinct Clinical Presentations and Outcomes of Hospitalized Adults with the SARS-CoV-2 Infection Occurring during the Omicron Variant Surge

The COVID-19 Omicron variant has imposed a tremendous burden on healthcare services. We characterized the types of the Omicron variant-associated hospitalizations and their associations with clinical outcomes. Consecutive adults hospitalized with COVID-19 during the Omicron variant surge period of 1–14 January 2022, were classified into one of three groups based on their clinical presentations on admission: Group 1—primary COVID-19; Group 2—extrapulmonary manifestations of COVID-19; and Group 3—incidental COVID-19. Of the 500 patients who were hospitalized, 51.4% fell into Group 1, 16.4% into Group 2, and 32.2% into Group 3. The patients in Groups 1 and 2 were older, with higher proportions of comorbidities than patients in Group 3. The Group 1 patients had the highest mortality rate (15.6%), followed by Group 2 (8.5%), and Group 3 (0.6%), with adjusted odds ratios (OR) of 22.65 (95% confidence interval [CI], 2.75–239.46; p = 0.004) and 10.95 (95% CI, 1.02–117.28; p = 0.048), respectively, compared to Group 3. Those in Group 1 showed a greater utilization of intensive care services (15.9%), followed by Group 2 (10.9%), and Group 3 (2.5%), with adjusted ORs of 7.95 (95% CI, 2.52–25.08; p p = 0.017), respectively, compared to Group 3. The patients in Groups 1 and 2 had longer hospitalization stays than the patients in Group 3 (p p = 0.002, respectively). Older age (≥65 years) was an independent factor associated with longer hospital stays (OR = 1.72, 95% CI, 1.07–2.77). These findings can help hospitals prioritize patient care and service planning for future SARS-CoV-2 variants
