A Double Whammy Pneumonia: The First Reported Case of Concurrent and SARS-CoV-2 Pneumonia.

Meningococcal pneumonia (MP) is a rare manifestation of meningococcal disease. The MP was first described in 1907 when (NM) isolates were identified in sputum samples obtained from soldiers with pneumonia. Preceding and concurrent viral infections constitute a major risk for MP.

Immune Thrombocytopenia following COVID-19 Vaccine.

Several vaccines have been developed and are being administered against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Common side effects include fever, chills, headache, myalgia, and soreness at the injection site. However, some rare adverse effects have also been reported.

A Case of Concurrent Disseminated Coccidioidomycosis and Embryonal Carcinoma When Lice and Fleas Coexist.

Coccidioidomycosis (CM) is a fungal infection endemic to the southwestern United States with a wide range of clinical presentations depending on the infected organ systems. Most infections are asymptomatic. Coccidioidomycosis causes a primary pulmonary infection and when symptoms occur, they most often resemble community-acquired pneumonia.

The First Case Report of Endocarditis Caused by .

The cases of human infections caused by are relatively rare. The few cases that have been reported primarily describe skin and soft tissue, urinary, and biliary tract infections. We describe a case of a 59-year-old man with infected bilateral lower extremity wounds who developed endocarditis due to confirmed with transesophageal echocardiogram.

A Case of S-Variant Hepatitis B Virus: An Immune System Escape Artist.

Genomic variants of the hepatitis B virus (HBV) preS/S protein are well-known to occur. Typically, immunity is gained through recovered HBV infection or by immunization. Very rarely, there are certain mutations that may enable HBV escape from the immune detection.

Wound Botulism in Black Tar Heroin Injecting Users: A Case Series.

The incidence of wound botulism in injection drug users has increased since the introduction of black tar heroin. Many species of the genus, most commonly , and , have been associated with wound botulism. Patients often present with progressive bulbar weakness, including dysphagia, cranial nerve palsies, and loss of speech, in addition to symmetrical descending weakness of the upper extremities that may progress to the chest and lower extremities.

An Unusual Case of Hemophagocytic Lymphohistiocytosis Presentation in Acute Human Immunodeficiency Virus.

Hemophagocytic lymphohistiocytosis (HLH) in acute human immunodeficiency virus (HIV) patients has been scarcely reported in the English literature. To the best of our knowledge, only 12 cases have been described. We present a case of a 27-year-old male with no past medical history who was admitted with a new-onset headache, fever, night sweats, and chills.

Non-Hodgkin's Plasmablastic Lymphoma as Initial Presentation of Human Immunodeficiency Virus.

Plasmablastic lymphoma (PBL) is a subtype of non-Hodgkin's lymphoma that manifests in patients with the diagnosis of human immunodeficiency virus (HIV), more prominently in the head, neck, and oral mucosal region. The diagnosis of this rare lymphoma serves as a concomitant diagnosis of acquired immunodeficiency syndrome. The case is of a 33-year-old previously healthy male, with an unknown diagnosis of HIV with a painful right mandibular mass.
