Pulmonary tumor thrombotic microangiopathy (PTTM) is a clinicopathologic disease entity in which the cells embolize to pulmonary vasculature leading series of maladaptive reactions including activation coagulation and fibrocellular intimal thickening. The resultant stenosis blood vessels leads hypertension eventual death from cor pulmonale. In this report, we present case PTTM presenting as initial manifestation metastatic gastric carcinoma young man. Although unusual its occurrence...

Pulmonary tumor thrombotic microangiopathy (PTTM) is a disease process wherein cells are thought to embolize the pulmonary circulation causing hypertension (PH) and death from right heart failure. Presented herein clinical, laboratory, radiographic, histologic features across seven cases of PTTM. Highlighted in this publication also involvement venules clinical distinguishing PTTM mimics. We conducted retrospective chart review hospitals greater Los Angeles metropolitan area. Patients series...

Boerhaave syndrome, a rare yet frequently fatal diagnosis, is characterized by the spontaneous transmural rupture of esophagus. The classic presentation syndrome Mackler's triad, consisting chest pain, vomiting, and subcutaneous emphysema. However, rarely presents with all features triad; instead, common includes or epigastric severe retching dyspnea, shock. These symptoms are typically misdiagnosed as cardiogenic in origin. Due to its atypical presentation, rarity, mimicry emergent...

Burst-suppression pattern on electroencephalography (EEG) occurs upon dissociation of the cortex from underlying brain structures. Unless is a physiologic consequence administered sedatives, this electroencephalographic indicative poor neurologic outcome and high mortality. We report case 29-year-old female thought to be dead based initial physical examination EEG findings burst-suppression, who was later found have supratherapeutic serum levels bupropion.

Right heart thrombus in transit (RHTT) is a rare, severe form of venous thromboembolism that carries high mortality rate. The optimal treatment for RHTT has not been well established. Thrombolysis therapeutic modality but the risk bleeding complications including intracranial hemorrhage. Low-dose thrombolysis shown to be effective treating submassive pulmonary emboli without an increased complications, it studied patients with RHTT. Here, we discuss case 74-year-old male lung cancer and...

Background: The confirmation of malignant pleural effusions (MPE) requires an invasive procedure. Diagnosis can be difficult and may require repeated thoracentesis or biopsies. F18Fluorodeoxyglucose-Positron Emission Tomography (FDG-PET) characterize the extent involvement in areas increased uptake. Patterns uptake pleura sufficient to obviate need for further procedures. Methods: This is a retrospective review patients with confirmed malignancy suspected MPE. Patients who underwent...

Aspirin's antithrombotic effect is mediated predominately by inhibition of platelet cyclooxyoenase-1, leading to a decline in serum thromboxane A 2 concentrations. We performed placebo-controlled, randomized, double-blind trial determine whether aspirin could be given at 3-day intervals and still achieve potent inhibition. One hundred nine healthy men women with no recent exposure contraindications its use participated. Subjects received 325 mg, 81 or 40 mg plain every third day, placebo on...

Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found tracheobronchial tree. We report first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic intra-abdominal lymphadenopathy. diagnostic bronchoscopy was performed where an incidental tracheal nodule discovered biopsied. Pathology...

Abstract Active (acylated) ghrelin is a peptide hormone secreted primarily by the stomach, positively associated with fasting, orexigenic, and promotes growth secretion. It therefore important to energy intake management. The objective of this pilot research was (1) compare active previous measurements leptin anthropometrics; (2) assess consistency across time in population; (3) extend our understanding potential population variation ghrelin. Two serum samples separated 10 days at same...

Abstract Objectives Voxelotor can increase hemoglobin levels in patients living with sickle cell disease (SCD). A clinician who is monitoring voxelotor response may want to know whole-blood concentration, but this cannot be measured most clinical settings. However, has been demonstrated cause “peak splitting” common methods of measurement such as capillary zone electrophoresis (CZE) and high-performance liquid chromatography (HPLC). We hypothesized that we could use the size peak split...
