Unexplained Hypoxemia in a Patient With Transient Ischemic Attack.

CASE PRESENTATION: An 84-year-old woman with a medical history of hypertension, hypothyroidism, and transient ischemic attacks presented with right-sided upper and lower extremity weakness for 1 day. She was a lifetime nonsmoker with no known heart disease or chronic lung disease. She had no occupational exposure or pertinent family history. She denied any fevers, chills, rashes, or shortness of breath. There was no history of recent travel.

Marijuana induced spontaneous pneumomediastinum.

Spontaneous pneumomediastinum (SPM), a rare occurrence, is defined by the presence of extraluminal gas in the mediastinum in the absence of trauma or underlying parenchymal disease. It is usually benign and has been associated with the inhalation of marijuana, cocaine, and amphetamines. The breathing maneuvers along with cyclical vomiting have been postulated as the underlying etiology. We present a case of a 27-year-old previously healthy male who presented with sudden onset chest pain and was found to have marijuana-induced pneumomediastinum.

Dyspnoea with progressive "idiopathic" pulmonary fibrosis.

Telomeres are repetitive nucleotide sequences that prevent chromosomal shortening in cell replication. Short telomeres have been implicated in the pathogenesis of interstitial lung disease. Patients with short telomere related pulmonary fibrosis can have computed tomography (CT) findings inconsistent with pro-typical usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF) pattern. They can have rapid progression and overall worse prognosis. Antifibrotic drugs, like pirfenidone, can be used to slow the progression of disease, but there is conflicting data in patients with Telomerase reverse transcriptase/Telomerase RNA component (TERT/TERC) mutations, hence genetic testing plays an important role in determining the therapeutic options. These patients should be referred for lung transplantation early. We present a case of rapidly progressive pulmonary fibrosis associated with short telomere.

Atypical Pyoderma gangrenosum: a case of delayed recognition.

Pyoderma gangrenosum (PG) is an inflammatory skin condition that is often misdiagnosed as a necrotizing infection. This diagnosis must be considered in any patient with underlying systemic disease who presents with large ulcerating lesions that are unresponsive to antibiotics. Early diagnosis and a multidisciplinary approach to treatment are crucial to achieving improvement in quality of life and minimizing cosmetic morbidity. .

Clomiphene- induced pulmonary embolism.

Pulmonary embolism and deep vein thrombosis are a major cause of hospitalization and cause high mortality. Several risk factors, such as smoking, immobilization, cancer, trauma, OCPs, pregnancy, and surgery, have already been identified. The diagnosis of PE can sometimes rely on high clinical suspicion. We report a case of a young 31-year-old male with no known risk factors, who developed a PE after 5 months of clomiphene therapy.

The many manifestations of a single disease: neuroborreliosis.

Lyme disease is a tick-borne illness that occurs in stages, multiple organs and tissue with highly variable clinical presentation. Most commonly, it presents with seventh cranial nerve palsy, often mimicking stroke and atypical rash (erythema migrans). Atypical presentations include abdominal pain, ileus/pseudo-obstruction and constipation thought to be due to autonomic dysfunction. Other less common presentations include Syndrome of Inappropriate Antidiuretic Hormones (SIADH). Lyme disease should be a differential when a patient presents from Lyme endemic areas with abdominal pain, constipation and SIADH in the setting of other causes of gastrointestinal and renal symptoms ruled out. Here we present a case of multisystem involvement in a single patient with Lyme Disease along with neuroborreliosis (neurological manifestation of Lyme disease).

Remdesivir in a pregnant patient with COVID-19 pneumonia.

Remdesivir is an antiviral drug currently being studied as a potential treatment of pneumonia caused by infection with SARS-CoV-2. The Adaptive Covid-19 Treatment Trial (ACTT-1) by NIH and the SIMPLE study by Gilead Sciences are two major trials that showed promising results of Remdesivir in the non-pregnant population. We are presenting the case of a pregnant patient who was diagnosed with COVID-19 pneumonia and successfully treated with Remdesivir.
