ABSTRACT
We present the case of a 19-year-old male with a history of sickle cell anemia who presented to the hospital with worsening lower extremity pain. Given his acute presentation and history of recurrent pain crises, he was admitted to the hospital for management of a suspected acute pain crisis. However, due to continued pain, imaging was obtained which revealed a different diagnosis for the cause of his symptoms. MRI of the left lower leg revealed heterogenous T1 and T2 hyperintense signals within the proximal tibial diaphysis measuring 6.6 × 1.6 × 2.2 cm with a thick rim of peripheral irregular enhancement with surrounding periosteal reaction and soft tissue edema, concerning for osteomyelitis and developing Brodie's abscess. The patient underwent tibia irrigation and debridement with the placement of vancomycin and tobramycin beads. Perioperatively, no purulence was noted within the soft tissues, and no organisms were grown on tissue cultures. The patient's pain improved and he was discharged home with a plan to complete six weeks of intravenous antibiotics. This case represents the need to differentiate Brodie's abscess from a sickle cell crisis. Clinicians should also be aware that patients with sick cell disease are prone to Brodie's abscess and it should be a differential for symptoms of relenting bone pain.
ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide, with an estimated prevalence of 25% globally. NAFLD is closely associated with metabolic syndrome, which are both becoming increasingly more common with increasing rates of insulin resistance, dyslipidemia, and hypertension. Although NAFLD is strongly associated with obesity, lean or nonobese NAFLD is a relatively new phenotype and occurs in patients without increased waist circumference and with or without visceral fat. Currently, there is limited literature comparing and illustrating the differences between lean/nonobese and obese NAFLD patients with regard to risk factors, pathophysiology, and clinical outcomes. In this review, we aim to define and further delineate different phenotypes of NAFLD and present a comprehensive review on the prevalence, incidence, risk factors, genetic predisposition, and pathophysiology. Furthermore, we discuss and compare the clinical outcomes, such as insulin resistance, dyslipidemia, hypertension, coronary artery disease, mortality, and progression to nonalcoholic steatohepatitis, among lean/nonobese and obese NAFLD patients. Finally, we summarize the most up to date current management of NAFLD, including lifestyle interventions, pharmacologic therapies, and surgical options.
ABSTRACT
OBJECTIVES: To review the characteristics and progression of hearing loss in MYH9-related disease (MYH9-RD) patients and present a unique case of bilateral non-simultaneous sudden sensorineural hearing loss (SNHL) in an MYH9-RD patient. MYH9-RD is a rare autosomal dominant platelet disorder. Patients with this disorder have a variable risk of developing SNHL. METHODS: A comprehensive literature search for scientific articles in PubMed, Scopus, and Web of Science that reported hearing loss outcomes in MYH9-RD patients. RESULTS: Initial search yielded 270 studies. Eight studies with a total of 23 patients met inclusion criteria and were used for data analysis. MYH9-RD patients typically present with progressive bilateral SNHL affecting predominantly the high frequencies. Mean age of hearing loss onset was 17.1âyears, progressing to severe-profound SNHL over a mean period of 14.4âyears. Seventeen of the 23 patients received cochlear implant (CI) at a mean age of 37.9âyears. In comparison, the study patient presented initially with bilateral progressive SNHL as a teenager and developed bilateral non-simultaneous sudden SNHL, first in her right ear at the age of 31 and 7âmonths later in her left ear at the age of 32. She is now a successful bilateral CI user. CONCLUSIONS: This is the first systematic investigation of the relationship between MYH9-RD patients and SNHL. Hearing loss in MYH9-RD patients is generally characterized as progressive SNHL. However, the study patient presented with the unique feature of bilateral non-simultaneous sudden SNHL, potentially expanding the hearing loss sequela associated with this disorder.
