Coccidioides-Induced Pyopneumothorax in an Immunocompetent Patient.

Coccidioidomycosis is a rare infection caused by the dimorphic fungi Coccidiodes immitus or Coccidioides posadasii. This fungal infection is very common in the American Southwest as well as northern Mexico. Though the fungus is ubiquitous, symptomatic coccidioidomycosis usually occurs in the elderly or immunocompromised. This case report discusses a unique instance of an immunocompetent 29-year-old male without any notable past medical history who was found to have a coccidioidal cavitary lung lesion with concomitant pyopneumothorax.

Homeless Patient With Community-Acquired Methicillin-Resistant Staphylococcus aureus Brain Abscesses.

Brain abscess secondary to community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection is a rare, yet highly fatal disease. This article presents the case of a 45-year-old homeless female with a medical history of bipolar disorder, seizure disorder, and substance use disorder who was admitted with altered mental status. Laboratory tests on admission revealed neutrophil-predominant leukocytosis, elevated inflammatory markers (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP]), and lactic acid. MRI brain demonstrated multiple cerebral abscesses with surrounding edema and sagittal vein thrombosis. The patient was initiated on broad-spectrum antibiotics and underwent a right-sided minimally invasive needle biopsy of the abscess and left frontal craniotomy for abscess evacuation, the culture of which confirmed the diagnosis of MRSA infection. As the patient did not have any hospitalization or procedure in the recent past, a diagnosis of CA-MRSA was made. The patient's clinical status improved following the procedure and antibiotic administration, but she left against medical advice before completing treatment. This case highlights the importance of early recognition and aggressive management of CA-MRSA infections, especially in vulnerable populations such as the homeless.

Inflammatory Myositis Following Statin Use in a Patient With Untreated Hypothyroidism.

Inflammatory myositis (IM) presents a diagnostic challenge due to its multifaceted etiology and varying clinical presentations. This case involves a 55-year-old male with asymptomatic hypothyroidism, recent statin use, and rapidly progressing proximal muscle weakness. He presented with profound weakness in the upper and lower extremities, severely impairing his daily activities. The patient's medical history included recent hospitalizations for idiopathic interstitial lung disease, myopericarditis, and pneumonia, adding complexity to his condition. Laboratory findings revealed elevated serum muscle enzymes, notably creatine kinase, indicating muscle damage and rhabdomyolysis. Serological testing confirmed the absence of myositis-specific antibodies and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies. The patient was eventually diagnosed with IM and rhabdomyolysis, likely secondary to statin use or hypothyroidism. Treatment with methylprednisolone, levothyroxine, and discontinuation of atorvastatin led to rapid improvements in AST levels and overall muscle strength. This case highlights the challenges of managing IM and emphasizes the importance of assessing thyroid function before initiating lipid-lowering therapy.

Superior Mesenteric Artery Syndrome in Systemic Lupus Erythematosus.

Although the gastrointestinal (GI) manifestations of systemic lupus erythematosus (SLE) are relatively less reported, they are common and occur in approximately half of individuals with SLE. These symptoms vary and include, but are not limited to, oral ulceration, dysphagia, nausea, vomiting, diarrhea, abdominal pain, and intestinal perforation. Gastrointestinal manifestations are often triggered by an inciting event, such as an infection or the side effects of medication. This case report presents a rare GI-related SLE complication, namely superior mesenteric artery syndrome.

Terbinafine-Induced Liver Injury: A Case Report.

Hepatic injuries attributable to terbinafine usage are a well-documented yet infrequent phenomenon. This case study details the clinical presentation and management of a 70-year-old Hispanic female, with no previous medical history, subsequently hospitalized for progressive jaundice, right upper quadrant abdominal discomfort, and worsening pruritus. A comprehensive review of her prior records revealed a recent terbinafine prescription for onychomycosis, which she took consistently for five weeks and then self-discontinued four weeks before her current admission. Laboratory tests on admission revealed a cholestatic pattern of liver injury, evident by transaminitis and conjugated hyperbilirubinemia. The R factor used to determine whether a liver injury is hepatocellular or cholestatic was 0.9. Further diagnostic imaging, including abdominal ultrasound, CT of the abdomen, and magnetic resonance cholangiopancreatography, failed to disclose an obstructive pathology, revealing only cholelithiasis and chronic cholecystitis. Therapeutically, the patient was initiated on hydroxyzine to address symptoms of pruritus, and then subsequently underwent a liver biopsy. Histopathologic findings from the biopsy revealed benign hepatic parenchyma demonstrating focal canalicular cholestasis, mild chronic inflammation involving select portal tracts, and chronic lobular inflammation, suggesting terbinafine-induced hepatotoxicity. This case highlights the challenges of diagnosing terbinafine-induced liver injury, emphasizing the need for a high index of clinical suspicion and recognizing the potential for prolonged symptomatic manifestation after drug discontinuation. This article provides valuable insights into the complexities inherent in such diagnoses and significantly enriches a medical provider's approach to diagnosing and treating unexplained liver injuries.
