Rare Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) Finding in a 9/11 World Trade Center Survivor: A Case Report.

Bronchial carcinoid tumors represent a relatively uncommon category within lung neoplasms, originating from neuroendocrine cells. The exact cause of these pulmonary tumors remains not fully understood. Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is characterized by widespread hyperplasia of these neuroendocrine cells, essential for regulating air and blood flow in response to stimuli such as hypoxia, dyspnea, and chronic obstructive pulmonary disease (COPD). The prognosis for bronchial carcinoid tumors hinges on factors such as grade and stage, with lung resection being the preferred treatment. A chest computed tomography (CT) scan unveiled diffuse bilateral pulmonary nodules with ground-glass opacities, leading to a right video-assisted thoracoscopic surgery (VATS) wedge resection. Immunohistochemical examination confirmed neuroendocrine differentiation, describing a lung wedge measuring 9 × 4 × 1.5 cm with spongy parenchyma and scattered white nodules.

Parvovirus Infection Leading to Severe Anemia in an Adult Patient With HIV Disease.

Individuals with human immunodeficiency virus (HIV) disease frequently suffer from anemia. The causes include anemia of chronic disease, vitamin B12 and iron deficiency, opportunistic infections (Mycobacterium tuberculosis, Pneumocystis jiroveci), HIV-related bone marrow suppression, AIDS-associated malignancies, and antiretroviral therapy (ART), specifically zidovudine. In HIV patients with advanced immunodeficiency, failure to produce neutralizing antibodies can lead to chronic parvovirus B19 (B19) infection. Normally, in persons with intact immunity, the progression of B19 is self-limited. However, in chronic B19 infection, it can lead to pure red cell aplasia (PRCA) and chronic anemia. In human immunodeficiency virus (HIV)-infected patients, B19-related anemia is rare and underdiagnosed. It has a great response to intravenous immunoglobulin (IVIG) therapy. Hence, early diagnosis and prompt treatment can significantly reduce mortality. In this article, we described the case of a 25-year-old male with HIV infection who presented with a headache. He had severe normocytic anemia with a low reticulocyte count. The workup for blood loss, hemolysis, hemoglobinopathy, and iron deficiency was negative. Because of extremely low reticulocytopenia with severe anemia, the investigations favored multiple myeloma, parvovirus infection, and bone marrow aspiration biopsy. He was tested for parvovirus B19 deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) test due to insufficient seroconversion. It turned out to be positive and he was treated with IVIG therapy.

A Rare Case of Empyema Complicated With Bronchopleural Fistula Secondary to Mucormycosis in a Young Immunocompromised Diabetic Patient With COVID-19.

Mucormycosis is an opportunistic fungal infection caused by the zygomycetes Mucor and Rhizopus. Most documented conditions and risk factors that predispose to mucormycosis are uncontrolled diabetes mellitus (DM), with or without ketoacidosis, hematological malignancies (HM), transplantation, immunosuppression, and chronic sinusitis. Pulmonary empyema secondary to Mucor in coronavirus disease 2019 (COVID-19)-infected patients is rarely documented. Here we present an extremely rare case of pulmonary empyema secondary to Mucor infection complicated by bronchocutaneous fistula in a human immunodeficiency virus (HIV)-infected patient in the setting of acute COVID-19 infection.

An Overview on Causes of Nonadherence in the Treatment of Rheumatoid Arthritis: Its Effect on Mortality and Ways to Improve Adherence.

Rheumatoid arthritis is one of the most prevalent musculoskeletal disorders that, when insufficiently treated, results in detrimental sequelae including joint damage and reduced quality of life. Poor patient adherence to medication is a significant blockade to effective management. The purpose of this review is to highlight and discuss the factors responsible for defiance of antirheumatic medication and ways to overcome these barriers. Education level, health literacy, cohabitation status, multi-morbidities, complicated drug regimen, intermittent co-payments, prescribed regimen adverse effects, and cognitive impairment are a few among many common barrier factors leading to poorer outcomes in rheumatoid arthritis. While there is an abundance of inhibitory factors leading to worsening disease progression, they each can be easily dealt with an effective approach at the beginning or during the treatment course to ensure a better outcome.

A Rare Case of Cocaine-Induced Muscle Hematoma Followed by Rhabdomyolysis in Association With Acute Kidney Injury and Severe Transaminitis.

Cocaine use can result in a few infrequent complications, among which is localized hematoma. As far as we know, there are very few cases reporting cocaine-induced non-traumatic muscle hematoma complicated by severe transaminitis and rhabdomyolysis. Here we present a patient who developed a significant lower extremity muscle hematoma secondary to inhalational cocaine use. We are reporting this case to bring to light this rare and unusual complication of cocaine use. With recreational use of this drug being so prominent in the patient population, early recognition of this complication can help expedite treatment and reduce the severity of end-organ damage.

Intraluminal Small Bowel Metastasis From Primary Lung Cancer.

Lung cancer is the leading cause of cancer-related death worldwide, with frequent metastases to the brain, liver, adrenal glands, and bone. The incidence of intraluminal small bowel metastases of the lung is extremely rare and poorly documented within the literature. Few case studies have been published since the late 1980s and early 1990s. However, little is known about this rare form of metastasis. Small bowel metastatic disease has atypical symptoms that mimic a variety of other diseases; as a result, signs and symptoms may be overlooked until the disease has progressed to a late stage. Signs of small bowel obstruction, symptomatic anemia, abdominal pain, and peritonitis are commonly reported signs and symptoms. Various modalities can be utilized for the workup of suspected small bowel metastasis, including positron emission tomography, computed tomography, and various forms of endoscopy. The prognosis for lung cancer patients with intestinal metastases is poor, with many only surviving months to a few years after diagnosis. Therefore, it is critical to consider small bowel masses as a differential diagnosis in a patient with primary lung cancer who demonstrates clinical signs consistent with symptomatic anemia secondary to gastrointestinal (GI) bleeding, peritonitis, or small bowel obstruction. We report an unusual case of intraluminal and fungating small bowel masses in a patient who had previously undergone lung resections and chemo-immunotherapy. She was diagnosed with non-small undifferentiated carcinoma with tumor necrosis over 12 years before disease recurrence in the bilateral lungs, right adrenal gland, bone, and small bowel. The discovery of the small bowel metastases occurred while undergoing treatment for advanced-stage disease. At this time, she completed chemo-immunotherapy and remained on maintenance immunotherapy. The patient also underwent a partial right adrenalectomy and radiotherapy to the right adrenal gland. Given that she was experiencing symptomatic anemia and further workup indicated that the GI masses were causing her anemia, she underwent palliative small bowel resection of the masses. The pathology results demonstrated that the masses originated from her primary lung cancer, confirming metastatic disease to the small bowel.
