[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.

[Pancytopenia and hemolysis--diagnosis, differential diagnosis and therapy of pernicious anemia]

Pernicious anemia and Vitamin B12 deficiency have a wide range of symptoms and are a common finding in the elderly. A 73 year old female is admitted to the hospital because of dyspnea, fatigue and loss of appetite and weight. While previous medical history and physical examination are inconspicuous, laboratory findings show severe pancytopenia with macrocytosis, low reticulocyte count and marked signs of hemolysis. A very low serum level of vitamin B12 and chronic atrophic type A gastritis upon endoscopy with presence of parietal cell antibodies in the serum lead to the diagnosis of pernicious anemia. Complete restitution is achieved by parenteral vitamin B12 substitution. Nowadays, severe pernicious anemia is only rarely seen. The differential diagnosis of pancytopenia (with macrocytic anemia) combined with hemolysis and the essential hints to the diagnosis of pernicious anemia are discussed, and thereby practical aspects including therapy actualized.

Pathophysiology and diagnosis of nephrocalcinosis

Nephrocalcinosis is the result of a myriad of hereditary or acquired diseases in the calcium, phosphate or oxalate metabolism that lead to deposition of calcium containing precipitates within the kidney. Nephrocalcinosis and nephrolithiasis are pathophysiologically tightly related and often co-exist. In the case of recurrent nephrolithiasis, nephrocalcinosis has to be excluded. Stone analysis can yield important clues to the underlying disease process. The best way to diagnose nephrocalcinosis and an accompanying nephrolithiasis is by native computer tomography scans. Untreated, nephrocalcinosis will lead to a progressive decline in renal function and eventually to end stage renal disease. Thus, for each case, the underlying disease process has to be determined and a causative therapy initiated.

Injuries to permanent teeth. Part 3: Therapy of root fractures

Diagnostic and therapeutic interventions following dental injuries are not part of the routine practice in the dental office. Quite often, these patients are emergency cases who seek treatment after normal office hours. The objective of this and the future papers is to present the current treatment concepts in dental traumatology at the School of Dental Medicine, University of Berne. The fruitful cooperation in the field of dental traumatology between the Department of Oral Surgery and Stomatology, and the Department of Conservative Dentistry (including pediatric dentistry and endodontology), is based on the interdisciplinary approach that has been established four years ago. Following discussion and evaluation of such treated cases, and considering current clinical and experimental studies, the said concepts have been worked out. The present paper describes the therapeutic approach for root fractures.

[Evaluation of the "Schema-focused Emotive Behavioural Therapy" (SET) for Patients with Personality Disorders: Results of a Randomised Controlled Trial.]

The "Schema-focussed Emotive Behavioral Therapy" (SET) was developed by our research group as a new group therapy approach for patients with personality disorders from all clusters (A to C; DSM-IV). It was evaluated in a randomised controlled study (n = 93). Data were collected before and after treatment as well as one year after study entry. A completer analysis was conducted with matched subgroups (n = 60). After therapy, SET patients improved in the outcome domains interactional behavior, strain, and symptomatic complaints (IIP-D, GAF, VEV-VW, BSI-P). Furthermore, they showed a significant lower dropout rate. At the follow-up assessment, Cluster C patients of the experimental group deteriorated with regard to symptomatic complaints (BSI-P). In contrast, cluster B patients improved more over time compared to control subjects. SET seems to be an adequate and effective group therapy with effects that seem to be stable over time, especially for patients with Cluster B diagnosis.
