Overlapping resonances in the control of intramolecular vibrational redistribution.

Coherent control of bound state processes via the interfering overlapping resonance scenario [Christopher et al., J. Chem. Phys. 123, 064313 (2006)] is developed to control intramolecular vibrational redistribution (IVR). The approach is applied to the flow of population between bonds in a model of chaotic OCS vibrational dynamics, showing the ability to significantly alter the extent and rate of IVR by varying quantum interference contributions.

[Rare primary localization of echinococcus cysts. Presentation of 2 cases and review of the literature]. / Le cisti da echinococco primitive a localizzazione rara. Presentazione di due casi e revisione della letteratura.

Hydatidosis is a parasitic disease. It's generally localized in the liver and in the lung even if any other organ can be potentially affected. From 92 to 98 our group observed two cases of rare primitive localisation of echinococcosis (one mediastinal and one retroperitoneal cyst). The patients performed serologic and instrumental exams to establish the right therapeutic strategy. Both of them were operated (it was carried out a pericystectomy with open cyst in one of them and an exeresis of the right adrenal gland including hydatid cyst in the other one). A patient underwent to Albendazole prophylaxis. During the follow-up the patients performed echography, CT and MRI. Considering the literature's data and their experience the authors emphasize: 1. The diagnosis of rare primitive localization of hydatidosis is very difficult. 2. The diagnostic iter requires a correct relationship between the laboratory and imaging data. 3. Only the exclusion of other localizations of the cyst (liver, lung or other organs) give us the possibility to diagnose a rare primitive localization of hydatidosis. 4. The treatment of hydatidosis is specifically surgical. 5. The surgeon can use several different approaches in relationship to the place and the anatomopathologic characters of the cyst.

[Role of ultrasonography in the control of patients receiving perioperative total parenteral nutrition]. / Ruolo dell'ecografia nel controllo di pazienti sottoposti a nutrizione parenterale totale perioperatoria.

BACKGROUND: On the basis of personal experience and literature, this study has been carried out in order to clarify the impact of ultrasonography on the diagnosis and prevention of hepatobiliary complications Total Parenteral Nutrition (TPN)-related. METHODS: Between April 1995-April 1997 in the Department of General Surgery-University of Catanzaro, 18 adult patients submitted to major thoracic or abdominal surgery, underwent to TPN for perioperative time (range: 9-55 days). In these patients ultrasonography was performed at pre-established days in pre- and postoperative time in order to diagnose precociously the possibility of hepatobiliary complications. RESULTS: Ultrasonography showed: 3 cases of hepatic steatosis, 5 cases of steatosis and gallbladder biliary sludge, 2 cases of gallbladder biliary sludge alone, 1 case of gallbladder biliary sludge with microlithiasis, 1 case of acute acalculous cholecystitis. The other 6 patients presented only little laboratory tests alterations, but normal ultrasonographic findings. CONCLUSIONS: Therefore it is underlined the importance of systematic ultrasonographic follow-up of patients on TPN as a non invasive method in the early diagnosis of hepatobiliary complications TPN-related. The good compliance of the patients to this instrumental investigation and the not excessive increase of their management's costs are also underlined.
