Image-directed color Doppler ultrasonography in the evaluation of superficial solid tumors

Image-directed color Doppler ultrasonography (ICDUS) studies of 86 patients with superficial solid masses yielded significantly lower resistive index (RI) values in acute inflammatory lesions, but no significant difference between the maximum systolic flow velocities (S) of the patient groups with malignant, benign, and acute inflammatory lesions. When analyzed separately, the malignant soft-tissue tumor subgroup was shown to have significantly higher mean RI compared to that of the malignant node subgroup. We conclude that RI may be useful in the differentiation of acute inflammatory masses from other pathological entities. Malignant soft-tissue tumors, especially sarcomas, may have different Doppler features from those of carcinomatous tumors. © 1995 John Wiley & Sons, Inc.     

Stereological evaluation of liver volume in living donor liver transplantation using MDCT via the Cavalieri method.

In living donor liver transplantation (LDLT), obtaining the precise volume of the graft is very important to decrease volume-related postoperative complications, especially in cases with suspected small-for size grafts. We used stereology based on the Cavalieri method (CM), a new method to measure liver graft volume, and compared the results with those obtained through intraoperative measurement (IOM) and through multidetector computed tomography (MDCT) measurement. Liver volumes estimated using the 3 methods were well-correlated with each other (r(2) = 0.94 and P < 0.001 for IOM and CM; r(2) = 0.91 and P < 0.001 for IOM and MDCT, and r(2) = 0.95 and P < 0.001 for CM and MDCT); however, they were different from each other (in descending order, 908 +/- 124 cm(2), 861 +/- 121 cm(2), and 777 +/- 168 cm(2) for MDCT, CM, and IOM, respectively). Although MDCT and CM overestimated the volumes, the results of CM were almost similar to those obtained via IOM. In conclusion, our results suggest that CM measured the liver graft volume more reliably. Thus, its use, particularly in cases with suspected small-for-size graft, may prove useful.     

Clinical symptoms and signs in sore throat patients with large colony variant β-haemolytic streptococci groups C or G versus group A

BACKGROUND: The role of large colony streptococci groups C or G as pathogen agents in sore throat has been questioned. AIM: To analyse clinical features of patients with large colony streptococci groups C or G compared with patients with group A streptococci (GAS) and with negative cultures. DESIGN OF STUDY: Prospective study of patients with sore throat. SETTING: Two Norwegian general practices in Stokke and Kongsberg communities with 6500 patients.METHOD: Frequency of clinical features in the three patient categories including the four Centor criteria (fever, anterior cervical lymphadenopathy, tonsillar exudates, and lack of cough), degree of pain on swallowing, pharyngeal rubor, C-reactive protein (CRP) values, patient age between 3 and 14 years, and duration of symptoms before seeing the doctor. A logistic regression analysis to find independent predictors was performed. RESULTS: Out of 306 patients with a sore throat, 244 were adults and 62 were children under 10 years old; 40% were men. One hundred and twenty-seven had GAS, 33 had streptococci groups C or G, and 146 had negative throat cultures. Forty-eight per cent of the GAS patients and 45% of the C or G patients met three or four of the Centor criteria. The logistic regression revealed that in patients with GAS considerable pain on swallowing, an age of 3-14 years and a duration of symptoms of < or =3 days or less were significantly associated with GAS infection in addition to the Centor criteria. The same results were found when all streptococci were analysed together, in addition elevated CRP was significant. In patients with streptococci group C or G an elevated CRP-value was significantly associated. CONCLUSION: Patients with tonsillitis caused by streptococcus groups C or G have, to a large extent, the same clinical picture as patients with GAS. Large colony streptococci groups C and G should be considered as throat pathogens in line with GAS.     

Intragastric blood flow in the etiology of duodenal ulcer--new aspects of surgical treatment

In the experiment on dogs and in patients with duodenal ulcer disease, it was established that the regulation of acid production besides the vagal nerves was mediated by the intragastric gastrin transport with the blood flow. A method of preoperative diagnosis of the intensity of intragastric blood flow permitting to define more accurately the indications for the choice of a method for surgical treatment has been developed. Supplementation of the selective proximal vagotomy with circular mucosectomy at the boundary between the antrum and body of a stomach enhances the effectiveness of operation due to reduction of the antral gastrin influence on the acid-producing zones of the stomach.     

Effect of vagotomy on intramural gastric plexus--the problem of reinnervation of the stomach after vagotomy

In dogs, only fundus and body, or antrum were denervated. At the period of up to 5 years after vagotomy, no complete parasympathetic reinnervation of the stomach occurs.     

Die verwendung der autologen vena femoralis bei vena-cava-superior-thrombose

We report on a 52-year old male patient who underwent implantation of an insulin pump because he had diabetes and in whom superior vena cava syndrome developed as a long-term complication. After unsuccessful lysis therapy superficial femoral vein was implanted to form a bypass from the internal jugular vein to the right atrium. The postoperative course was uneventful from the aspects of both the bypass and the leg after explantation of the superficial femoral vein. The bypass is still patent 7 months after the operation, and the patient has no symptoms. Autogenous superficial femoral vein can be used successfully in the reconstruction of large venous vessels. It should be the graft of choice for young patients with benign diseases. We compare our result and those obtained with different substitutes described in the literature that have been used for reconstruction in superior vena cava syndrome.

Die verwendung der autologen vena femoralis bei vena-cava-superior-thromboseFallbericht mit literaturübersicht

Zusammenfassung Bei einem 52jährigen, männlichen Patienten trat nach Implantation einer Insulinpumpe als Spätkomplikation eine Thrombose der Vena cava superior auf. Nach erfolgloser Lysetherapie wurde ein Venajugularis-rechtsatrialer-Venenbypass mit autologer Vena femoralis durchgeführt. Der postoperative Heilungsverlauf war sowohl von Seiten des gefäßrekonstruktiven Eingriffs, als auch von Seiten der Venenentnahmestelle komplikationslos. Der Bypass ist 7 Monate postoperativ offen und der Patient beschwerdefrei. Die autologe Vena femoralis eignet sich zur Rekonstruktion großer venöser Gefäße ausgezeichnet. Sie sollte v. a. bei benignen Prozessen und jüngeren Patienten als autologes Bypassmaterial dem Kunststoff vorgezogen werden. Das Ergebnis wird mit verschiedenen Gefäßsubstituten, die bei Verschluß der oberen Hohlvene verwendet werden, verglichen.

     

Orofaziale Regulationstherapie nach Castillo Morales

The goal of Castillo-Morales’ orofacial therapy is to improve the coordination of oral motor functions in cooperation with other body systems. The processes involved in sucking, biting, chewing and swallowing are stimulated by specific techniques of sensory stimulation such as touching, stroking, stretching, exerting pressure or the vibration of mimic and tongue-bone musculature, as well as massage of the gums and palate or the application of technical apparatus. Sufficient head and posture control is fundamental and must be the first goal. Successful therapy, especially for ICP-children, has been documented in progress reports and case studies. As yet, however, there is no evidence of specific effects on eating and speech functions. Therefore, the therapy can be recommended only in order to achieve specific goals and for a limited time, being aware of the risk of overstimulation.     

Ruptur der langen Bizepssehne und operative Therapiestrategien

Zusammenfassung Die Ruptur der langen Bizepssehne beruht auf ihrer anatomischen Disposition und, bedingt durch die biomechanische Belastung, zu 90% auf degenerativen Veränderungen. In der Regel finden sich begleitende Verschleißschäden anderer Strukturen des Schultergelenks wie der Rotatorenmanschette. Es wird ein Überblick über die Häufigkeit und den Entstehungsmechanismus von Rupturen der langen Bizepssehne sowie gängige operative Behandlungskonzepte gegeben. Die Rolle und das anatomisch-funktionelle Prinzip der Sehne des Caput longum im komplexen dynamischen System des Schultergelenks werden erläutert. Eingang finden die klinische Symptomatik, Beschreibungen sowie Wertungen apparativer diagnostischer Verfahren. Der Stand derzeit etablierter Operationstechniken wird unter Darstellung von Vor- und Nachteilen beleuchtet und diskutiert. Des Weiteren werden die selbst favorisierte Methode und die gesammelten Erfahrungen dargestellt.
