Schock

Shock is defined as a disproportion between oxygen supply and consumption based on a deficient perfusion of vital organs. Reduction of circulating blood volume (hypovolemic shock), cardiac failure with low output (cardiac shock) or the failure of peripheral vascular resistance (distributive shock) can result in shock. Preclinically the diagnosis of shock is determined by exploration, physical examination and – some – monitoring only. Therapy is directed towards the underlying cause whilst recovery and maintenance of adequate perfusion of vitals and tissue are of primary importance. This strategy includes the application of oxygen, fluids and catecholamines. Moreover, the choice of the hospital for further therapy is crucial in case of emergency.     

Cervical metastases of microcystic adnexal carcinoma in an otherwise healthy woman

Microcystic adnexal carcinoma is a rare cutaneous neoplasm characterized by slow but locally aggressive growth, which normally does not lead to systemic metastasis. Frequent local recurrences are reported, which are most likely due to insufficient operative technique. We present the fourth case of cervical ipsilateral metastatic microcystic adnexal carcinoma in an otherwise healthy woman. The patient presented with a previously diagnosed but not completely resected microcystic adnexal carcinoma in the area of the right posterior scalp and two palpable ipsilateral lymph nodes. The tumor was resected using intraoperative snap frozen histological evaluation of the resection borders. In the same procedure two lymph nodes were resected from the right neck. The lymph nodes were histologically assessed and showed infiltration by small strains of tumor cells. After exclusion of a second primary tumor, e.g., mammary carcinoma, as the cause for cervical lymph node metastases, we performed a modified radical neck dissection with resection of the sternocleidomastoid muscle and the accessory nerve, which was histologically proven to be perineurally infiltrated by tumor cells. In this second procedure the histological evaluation of the specimen showed no sign of remaining tumor infiltration. After exclusion of distant metastasis the patient was irradiated with 60 Gy. The patient is well 1 year after the initial treatment without signs of recurrence.     

Über den Angeblichen Thrombocytensteigernden Faktor T des Sesamoels

Zusammenfassung Bei normal ernährten und Vitamin A-frei ernährten Ratten wird bei Sesamölzugabe keine Erhöhung der Thrombocyten beobachtet. Auch bei Gesunden und Kranken mit einer relativen Thrombopenie gelang es nicht, durch Verabreichung von Sesamöl die Thrombocyten zur Norm zu steigern. Die Anwesenheit des Faktors T im Sesamöl wird abgelehnt.     

Assessment of tardive dyskinesia by means of digital image processing

A wireless device for the assessment of tardive dyskinesia by means of digital image processing is presented. Four skin-cream dots placed around the subjects' mouth are recorded by a video camera. The image is passed to a framegrabber with a signal processor, where it is converted from analogue to digital. A fast spot-detecting algorithm implemented on the signal processor tracks the dots and passes the information to a personal computer, where a Fourier transformation is performed to calculate the frequency spectrum of the movements. The device provided detailed information on the magnitude and on the frequencies of the movements. Data from a longitudinal investigation suggest a higher sensitivity and reliability than conventional rating scales to detect and evaluate abnormal perioral movements. The device might be useful for the early detection, for the longitudinal assessment (p.e. clinical trials) and in some cases for the differential diagnosis of tardive dyskinesia, thus providing a tool for both research and clinical purposes.     

Cor pulmonale caused by recurrent pulmonary emboli

A 53-year-old black man developed femoral thrombophlebitis in 1983 following a Harrington nail implantation in his first lumbar vertebral region. There was evidence of pulmonary embolization at that time and recurrently until he developed ventricular fibrillation and died in 1987. The terminal event followed a hypotensive episode during the course of a right ventricular catheterization. Autopsy confirmed the clinical impression that he had multiple recurrent thromboemboli to his lungs. After several years of embolization, the pulmonary arterial circulation was sufficiently occluded to result in pulmonary hypertension. Cor pulmonale was produced, with congestive heart failure leading to a progressively downhill course in the 4 months before his death.     

Tibial fractures following Maquet's tuberosity advancement. Apropos of 2 clinical case reports

Although accustomed to using the Maquet tibial tuberosity advancement, the authors had two similar and rare complications in which a fracture of the tibial shaft occurred at the end of the vertical osteotomy. Both incidents arose from a mechanical incision effect. This can be prevented by making a larger circular hole in the distal portion of the osteotomy.
