Drug-induced Liver Injury Due to a Horse Chestnut Dietary Supplement.

Drug-induced liver injury (DILI) is the most common cause of acute liver failure in the Western world. In recent years, natural herbal and dietary supplements have become widely available to the general public and have increased in popularity. Reports of idiosyncratic liver injury caused by such supplements have also increased over the last decade. Horse chestnut is a herb used in dietary supplements primarily for complications of venous insufficiency. Clinically significant acute liver injury has been very rarely associated with its use. We present the case of a 70-year-old man with idiosyncratic horse chestnut-induced liver injury. LEARNING POINTS: Idiosyncratic drug-induced liver injury is one of the most challenging liver disorders.Herbs and natural dietary supplements are widely popular and should be considered when evaluating liver injury of unknown origin.Patients may not consider herbs and supplements to be drugs with the potential to cause adverse effects, requiring a more careful medication history.

Iron pill aspiration: Cytologic and histologic findings of a potential life-threatening airway injury. A Case report and literature review.

Iron pill-induced injury of bronchial mucosa is a complication following accidental aspiration of an iron tablet. Oral iron supplementation is a common therapy, particularly among advanced-age patients, who are more prone to aspiration. However, iron pill aspiration has been rarely reported in the literature, usually under the format of short case reports, with only 32 cases published in the literature. The cytologic features suspicious for this rare but potentially lethal entity have been seldom described. We report a case of a patient diagnosed with iron pill-induced bronchial injury, after oral ferrous sulfate has been prescribed during a hospital admission for pneumonia. In the bronchial washing specimen, a background of necrotic cell debris and acute inflammation involving extracellular golden-brown fibrils positive for iron stains was seen, along with the yeast forms, which, in this clinical context could confirm the iron pill aspiration. Our aim is to highlight the cytology features associated with iron pill aspiration bronchitis, and to review the literature for the histologic, clinical, bronchoscopy, and treatment aspects.

Sternoclavicular septic arthritis due to methicillin-resistant Staphylococcus aureus in a patient with a suprapubic catheter.

We report a case of a 74-year-old man who presented to the emergency department with a 1-week history of fever. He had a meatal stenosis and had a suprapubic catheter for 10 months, and had a recent hospitalisation for urosepsis with bacteraemia due to methicillin-resistant Staphylococcus aureus after manipulation of the catheter. Clinical examinations were performed in the emergency department and the patient was hospitalised with the diagnosis of recurrent urinary tract infection. The following day, we noticed the development of a mass in the left sternoclavicular joint with inflammatory signs and excruciating pain. Ultrasonographic findings led to the diagnosis of left sternoclavicular synovitis, and methicillin-resistant S. aureus grew in blood cultures leading to the diagnosis of sternoclavicular septic arthritis. Treatment with vancomycin and gentamicin was started and maintained for 4 weeks with complete resolution of symptoms and no complications or sequelae.
