ABSTRACT
Phlegmonous gastritis is a rare disease of acute suppurative inflammation in the stomach wall. It is rapidly progressive and potentially fatal. Its mortality rate remains very high because the clinical diagnosis is often delayed. Many patients with phlegmonous gastritis undergo surgery. We present the case of 63-year-old woman with epigastric pain, fever, nausea and vomiting. The presumed diagnosis of acute phlegmonous gastritis was made by esophagogastroduodenoscopy, abdominal computed tomography, endoscopic ultrasonography and deep submucosal biopsy assisted with hook knife. Acinetobacter baumannii was cultured in the aspiration from the stomach. We treated the patient with antibiotics alone. Early recognition of phlegmonous gastritis by endoscopic biopsies and bacteriological study may improve the prognosis of these patient.

Hypoxic pulmonary vasoconstriction is a unique response of the pulmonary circulation to hypoxia. It constitutes part of the self-regulatory mechanism by which pulmonary capillary blood flow is adjusted to alveolar ventilation for maintaining the optimal balance of ventilation and perfusion. In pathological conditions, hypoxic pulmonary vasoconstriction may occur as an acute episode or as a sustained response with pulmonary hypertension and vascular remodeling. We report a case of reversible pulmonary hypertension induced by acute hypoxic pulmonary vasoconstriction in an 18-year-old man with relapsed acute myeloid leukemia, complicated with severe anemia and pneumonia.

We report a case of pneumonia caused by Aspergillus terreus and cytomegalovirus (CMV) in a patient with acute myleogenous leukemia (AML) after remission induction chemotherapy. A 19-year-old woman underwent chemotherapy for AML. Twenty-three days after completing chemotherapy, she experienced a neutropenic fever with a rapidly-progressive pulmonary infiltration. In those days, her serum galactomannan immunoassay was 4.7 and she was treated with intravenous voriconazole (6 mg/kg q12h for 2 doses, followed by 4 mg/kg q12h) because of persistent fever and radiological worsening, despite the administration of amphotericin B deoxycholate (1 mg/kg q24h) for 7 days. A chest CT showed wedge-shaped consolidation with a central hypodense lesion and an air-crescent sign in the right middle lobe. With maintenance therapy of oral voriconazole for 10 weeks, a partial response was shown and neutrophil count was still less than 100/mm3. A lobectomy of the right middle lobe was performed. A. terreus was discovered from the lung tissue. At the same time, giant cells with intranuclear inclusions were found and immunohistochemical staining for CMV was positive. Ganciclovir (5 mg/kg q12h) was added to voriconazole therapy for 3 weeks after surgery, and then cord blood hematopoietic stem cell transplantation (HSCT) was performed. During HSCT, foscarnet (60 mg/kg q12h) was substituted for ganciclovir, and both antiviral agents were used alternatively due to CMV DNAemia. After 83 days from HSCT, the patient achieved successful engraftment and discharged without worsening the pneumonia.

A 55-year-old woman was referred to our hospital with a 6-month history of dyspnea (NYHA II-III). The physical examination revealed a grade 2/6 "tumor plop," i.e., a low-pitched sound heard during early or mid-diastole. The chest X-ray showed mild cardiomegaly with lung congestion in both lower lung fields. Two-dimensional echocardiogram showed a large myocardial mass, prolapsing into the left ventricle during diastole. Chest computed tomography showed a multi-lobulated mass (6.8x4.1 cm) attached to the interatrial septum during systole and prolapsing into the left ventricle during diastole. Coronary angiography demonstrated large tumor vessels arising from and surrounding the posterior lateral branch of the right coronary artery. The mass was excised and the patient recovered uneventfully.
