An increase in serum lactate dehydrogenase (LDH) activity is commonly taken to support the presumptive diagnosis of Pneumocystis carinii pneumonia (PCP), although the LDH level may also be increased in other lung infections and in a variety of extrapulmonary disorders. To assess its diagnostic value in patients with fever, lung infiltrates, and a high(More)
Pretracheal abscess due to endotracheal intubation has not been reported in literature. We present a case of a female patient who was admitted with acute hypercapnic respiratory failure. Patient was initially managed with noninvasive ventilation but eventually was intubated after sustaining a cardiac arrest. She could not be extubated because of poor(More)
Clozapine is the preferred antipsychotic used for the treatment of resistant schizophrenia with suicidal ideation. The drug is started at a low dose and gradually increased to a target dose of 300-450 mg/day. It is well known to cause agranulocytosis and neutropenia. Several cases of fatal sepsis have been reported in neutropenic patients and emphasis is(More)
Obstructive fibrinous tracheal pseudomembrane (OFTP) is a relatively rare cause of failed extubation. OFTP may be more common than described in the literature. OFTP results from ischemic injury to tracheal mucosa and may be the initial stage of the development of tracheal stenosis. Early diagnosis and treatment can prevent re intubation and mortality. We(More)
BACKGROUND Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) present with a variety of sleep-related symptoms. In polysomnography, sleep architecture is almost always abnormal, but it is not known which of the sleep-stage abnormalities are related to symptoms. Finding key sleep-stage abnormality that cause symptoms may be of therapeutic(More)
Lung cancer is one of the most common cancers in America. Frequent sites of metastasis include the Hilar lymph nodes, adrenal glands, liver, brain, and bone. The following case report is of a primary lung cancer with metastases to the breast and skin. Case. A 48-year-old African American male with a past medical history of poorly differentiated left breast(More)
We are reporting the case of a 37-year-old immunocompetent patient who presented with anterior chest wall swelling, jaw swelling and pain, back pain, night sweats, and unintentional weight loss. He underwent mediastinoscopy with lymph node biopsy, which revealed caseating and noncaseating granuloma and special stains positive for acid-fast bacteria.(More)
Foreign body aspiration (FBA) is more common in children than adults with about 80% occurring in children aged less than 15 years. FBA in adults is often overlooked as a potential cause of airway obstruction especially if there is no asphyxiation. We present a case of a 45-year-old male with alcohol abuse who presented with post-obstructive pneumonia(More)
Primary Pulmonary Diffuse Large B Cell Lymphoma (PPDLBCL) is an extremely rare entity, which exhibits an aggressive behavior by compressing local blood vessels. It represents only 0.04% of all lymphoma cases and is extremely rare in young age. We present a case of a primary pulmonary lymphoma with superior vena cava syndrome (SVCS) in a young female.(More)
Obstruction of the thoracic duct may lead to accumulation of a lymphatic fluid rich in triglycerides named chyle. When chyle accumulates in the pleural cavity, it becomes a chylothorax. Malignancy, particularly lymphoma, is the most common cause of chylothorax; however, any pathology leading to obstruction or destruction of the thoracic duct can lead to a(More)
