Concurrent Delusions of Ocular Parasitosis and Complex Visual Hallucinations from Charles Bonnet Syndrome Treated Successfully with Aripiprazole in an Elderly Male: A Case Report.

Introduction: Delusional parasitosis (DP) has been described as among the most challenging diagnosis to manage in dermatology and psychiatry literature. Patients with this perplexing and enigmatic condition present potentially to a wide range of specialties including primary or emergency care, dermatology, infectious diseases, neurology, and psychiatry. DP is probably underdiagnosed from patients' underreporting of symptoms of being infested with parasites, resulting from the associated social stigma.

Altered mental status in an elderly woman with concurrent takotsubo syndrome and polymyalgia rheumatica: a case of treatable geriatric delirium.

We present a unique case of a patient, aged 80 years, who presented with delirium and takotsubo syndrome. Also known as "broken heart syndrome" because it often originates following an emotional stress, takotsubo syndrome may be difficult to distinguish from myocardial infarction because of similar symptoms and demographics. However, the distinction of these opposing diagnoses is significant because takotsubo syndrome is associated with more favorable prognosis for complete recovery, especially with early diagnosis and expedient supportive therapy.

Gastric antral vascular ectasia (watermelon stomach)-an enigmatic and often-overlooked cause of gastrointestinal bleeding in the elderly.

Gastric antral vascular ectasia (GAVE) syndrome, also known as watermelon stomach is a significant cause of acute or chronic gastrointestinal blood loss in the elderly. is characterized endoscopically by "watermelon stripes." Without cirrhosis, patients are 71% female, average age 73, presenting with occult blood loss leading to transfusion-dependent chronic iron-deficiency anemia, severe acute upper gastrointestinal bleeding, and nondescript abdominal pain.

Cervical myelopathy from spinal sarcoidosis as the unexpected initial presentation for systemic sarcoidosis.

This is a case which highlights unique diagnostic challenges in the evaluation of a previously healthy patient presenting with a myelopathy initially most concerning for malignancy. However, timely recognition and nonoperative therapy of unexpected spinal sarcoidosis with corticosteroidal therapy was crucial in averting the sequelae of undiagnosed or misdiagnosed neurosarcoidosis, which can be devastating and life-threatening. Diagnosis is challenging due to significant similarities in clinical and roentgenographic findings of spinal sarcoidosis with infection, inflammation, and malignancy.
