[Spontaneous bacterial peritonitis]

Spontaneous bacterial peritonitis (SBP) is the most frequent infection in patients with cirrhosis during hospitalization and is associated with high acute and long-term mortality. Diagnosis is made by paracentesis with determination of neutrophil count in ascitic fluid. Empirical antibiotic therapy must be initiated immediately. The choice of drug is dependent on prior therapies. Liver transplantation has to be considered in the absence of contra-indications. Prophylaxis of SBP is indicated in patients with ascites and gastrointestinal hemorrhage, and in patients after SBP. Primary prophylaxis should be considered in high-risk patients with cirrhosis and ascites. The development of resistance to antibiotic drugs is a relevant side-effect.

[A rare cause of cardiogenic shock with psychotic symptoms]

A 40-year-old man was admitted to the emergency department with psychotic symptoms and marked hypothermia. He was known to have had a macroadenoma of the pituitary gland which had been excised 10 years before. No information about his current medication was available. Several hours after admission the patient developed signs of acute cardiac failure and cardiogenic shock. He was admitted to the intensive care unit, intubated and treated with vasoactive drugs. Later investigations revealed that the patient had stopped his hormonal therapy (hydrocortisone and thyroxine) at least 3 months previously.

[Pulmonary microscopic tumor embolism syndrome]

HISTORY: A 76-year-old woman and a 62-year-old man were both referred to our clinic because of an unexplained weight loss, increasing dry cough and shortness of breath. INVESTIGATIONS: Investigations revealed an adenocarcinoma of the colon with retroperitoneal, mediastinal and supraclavicular lymph node metastasis and poorly differentiated carcinoma of the prostate with extensive bone metastases. During their hospital stay both patients developed increasing shortness of breath and clinical signs of right heart failure. Echocardiography confirmed severe pulmonary hypertension and dilatation of the right ventricle in both patients. Despite the high degree of clinical suspicion CT scans of the thorax could not demonstrate pulmonary embolism. DIAGNOSIS, TREATMENT AND COURSE: During the following days the patients condition deteriorated further and both patients' died from irreversible right heart failure. Both autopsies showed extensive metastatic adenocarcinoma with marked angiosis carcinomatosa of the lungs with numerous occlusions of small arteries and arterioles and resulting cor pulmonale. Thrombotic pulmonary embolism could not be detected. CONCLUSION: In patients with malignant neoplasms, especially adenocarcinomas, dyspnea and signs of increasing pulmonary artery pressure, the possibility of a microscopic pulmonary tumor embolism should be considered after exclusion of more usual causes especially thrombotic pulmonary embolism. In selected cases a cytologic examination of blood aspirated from a wedged pulmonary artery catheter can be performed to prove angiosis is carcinomatosa.

Aussergewöhnliche Manifestation eines Magenkarzinoms mit Meningeosis carcinomatosa und spinaler Metastase

BACKGROUND: Leptomeningeal carcinomatosis is a rare complication of solid tumors, e. g., breast, lung and gastrointestinal carcinomas. Clinical manifestations are variable with radicular pains with or without neurologic deficiencies as well as headache and hallucinations. CASE REPORT: The rare case of a 57-year-old patient with neurologic symptoms caused by a leptomeningeal carcinomatosis and a spinal metastasis of an asymptomatic signet-ring cell gastric carcinoma is reported. In spite of combined radiochemotherapy the patient died already 4 weeks after discharge from hospital due to an intracerebral hemorrhage. CONCLUSION: Until today, prognosis of leptomeningeal carcinomatosis is poor with a median survival between 3-4 months independently of the primary tumor.
