Unusually high creatine kinase in a case of rhabdomyolysis without acute kidney injury: a case report.

Background: While rhabdomyolysis frequently leads to hospital admissions, typically following trauma, recurrent occurrences are relatively rare, accounting for just 10% of cases. For young patients experiencing repetitive episodes without an apparent cause, a comprehensive investigation into the possible etiologies is crucial. Recognizing the atypical nature of recurrent rhabdomyolysis is crucial and a thorough workup encompassing evaluations for potential endocrine, inflammatory, and metabolic etiologies is recommended.

A case of culture-negative endocarditis causing flail perforated mitral valve.

We describe a case of culture negative endocarditis causing mitral valve perforations and recurrent heart failure admissions.

A Case of Sinus of Valsalva Aneurysm Rupture Causing Cardiogenic Shock.

A sinus of Valsalva aneurysm (SVA) is an abnormal dilation between the aortic valve annulus and sinotubular junction resulting from weakness in the elastic lamina. In the vast majority of cases, SVAs are asymptomatic and are incidentally detected on echocardiogram imaging. In some cases, they can rupture and lead to an intracardiac shunt.

A Rare Case of Mycotic Aneurysm Due to Methicillin-Sensitive Staphylococcus aureus (MSSA) Bacteremia.

Mycotic aneurysm is defined as an infection of the arterial wall either by fungi or bacteria. Although, a rare complication of infection, it is associated with high morbidity and mortality. We describe a 69-year-old female with a rare thoracic aortic mycotic aneurysm, with no clear source of infection and a predominantly atypical presentation, manifesting primarily as heart failure, at a rural community hospital.

Severe Refractory Hypocalcemia Caused by Denosumab.

Denosumab is a fully human monoclonal antibody that binds to the receptor activator of nuclear factor kappa-Β ligand, an essential cytokine factor in bone resorption, which reduces bone resorption and has been shown to decrease the incidence of skeletal-related events in patients with malignancy and bone metastasis. Severe hypocalcemia is a rare and life-threatening adverse effect of denosumab therapy. Here, we discuss the case of a patient with stage 4 estrogen receptor-positive, progesterone receptor-negative, human epidermal growth factor receptor 2-negative breast cancer who was on treatment with denosumab for bony metastases and presented with severe refractory hypocalcemia.

COVID-19 Bullous Lung Disease Superinfection by Raoultella planticola.

Bullous lung lesions from coronavirus disease 2019 (COVID-19) pneumonia, causing pneumothorax, are a rare complication, affecting up to 1% of infected patients. is an aerobic, gram-negative bacteria known to cause opportunistic infection. We present a rare case of spontaneous pneumothorax from rupture of lung bulla as a late sequela from COVID-19 pneumonia and superinfection of the bulla by .
