Time-zero limits of Kaden's spirals and 2D Euler

The present note is devoted to the studies of the relation of the time-zero limits of Kaden's spirals and the 2D Euler equation. It is shown that the time-zero limits of Kaden's spirals satisfy inhomogeneous 2D Euler in a weak sense. As a corollary, the necessity of both, the decay of spherical averages around the origin of the spiral as well as the velocity matching condition, for the 2D Euler equation to hold in a weak sense, is shown. Finally, some preliminary results concerning the Kaden spirals are obtained

The role of MR cholangiography in the detection of biliary complications after orthotopic liver transplantation

Background: To assess the usefulness of magnetic resonance cholangiography (MRC) in the diagnostics of biliary complications after liver transplantation. Material/Methods: In 40 patients (17 men, 23 women) 51 MRC examinations were performed, from 1 to 58 months (mean-12) after liver transplantation. Studies were performed with 1.5 T unit. The imaging protocol consisted of tree hydrographic TSE sequences: 2D, 3D and single-slice technique. The results were compared with ERCP (n=10), percutaneous cholangiography (n=4), T-tube cholangiography (n=1), T-tube cholangiography and percutaneous cholangiography (n=1), T-tube cholangiography and ERCP (n=1), fistulography (n=2) and histopathology (n=3). In remaining patients other imaging studies (US, CT), laboratory liver functions tests and clinical status were evaluated. Results: In 46 cases (90%) abnormalities of biliary tract were depicted. Following biliary complications were diagnosed: dilatation of biliary tree (n=29), biliary strictures located beside anastomosis site (n=19), anastomotic biliary strictures (n=17), intrahepatic strictures (n=7), biliary obstruction (n=2), biliary stones/sludge (n=14), bile leak (n=12). In 5 cases (10%) MRC was normal. In 50 cases (98%) there was concordance between MRC results and the standard of reference, 1 remaining case (2%) of bile duct ischemia was not confirmed by other studies. Conclusions: MRC is a noninvasive modality, providing accurate assessment of biliary complications in patients after liver transplantation

Wielomiesięczny czas wolny od progresji u chorej z uogólnionym nowotworem neuroendokrynnym jelita cienkiego po leczeniu skojarzonym oktreotydem LAR i terapią izotopową

Long-acting somatostatin analogs are considered as a first line of treatment in well-differentiated metastatic gastroenteropancreatic neuroendocrine neoplasms with symptoms of carcinoid syndrome, because of relief symptoms and antiproliferative effect. According to the results of PROMID study (Placebo-Controlled, Double-Blind, Prospective, Randomized Study on the Effect of Octreotide LAR in the control of Tumor Growth in Patients With Metastatic Neuroendocrine Midgut Tumors), median time to progression is 14.3 months during treatment with octreotide. In this case report we presented 46-year-old woman with primary diagnosis of hepatocellular carci­noma, treated with palliative chemiotherapy (doxorubicin, dexamethasone, cyclophosphamide) with hematologic side effects and after that in follow-up. Because of uncommon course of HCC, histopathology examination was reviewed. The new diagnosis was metastases of well-differentiated neuroendocrine tumor (G1 in WHO 2010 clas­sification). During diagnostic imaging (computed tomography of chest and abdomen, Gallium-68-DOTA-TATE PET/CT) primary tumor in small intestine was found. The final diagnosis was well-differentiated neuroendocrine neoplasm of small intestine with distant metastasis and carcinoid syndrome. Improvement of general condition and 26 months stabilization of the disease was observed after concomitant treatment with long-acting octreotide and peptide receptor radionuclide therapy.Leczeniem farmakologicznym z wyboru w nowotworach neuroendokrynnych przewodu pokarmowego przebiega­jących z objawami zespołu rakowiaka są długodziałające analogi somatostatyny, redukujące objawy aktywności hormonalnej guzów oraz mające działanie antyproliferacyjne. Według danych badania PROMID średni czas wolny od progresji podczas leczenia długodziałającym oktreotydem wynosi 14,3 miesiąca. Prezentowany przy­padek dotyczy 46-letniej kobiety z rozpoznanym początkowo rakiem wątrobowokomórkowym (HCC), leczonym chemioterapią paliatywną (doksorubicyna, deksametazon, cyklofosfamid), a następnie z powodu powikłań hematologicznych pozostawionym w obserwacji. Ze względu na nietypowy przebieg HCC poddano weryfikacji badanie histopatologiczne, rozpoznając przerzut wysokozróżnicowanego nowotworu neuroendokrynnego (G1 wg WHO 2010). W wykonanych badaniach obrazowych (tomografia komputerowa klatki piersiowej i jamy brzusznej, 68Ga-DOTA-TATE-PET/CT) uwidoczniono zmianę w jelicie cienkim, mogącą odpowiadać ognisku pierwotnemu. Rozpoznano wysokozróżnicowany nowotwór neuroendokrynny jelita cienkiego w fazie uogólnienia przebiegający z objawami zespołu rakowiaka. Po zastosowanym leczeniu skojarzonym długodziałającym analogiem somato­styny — oktreotydem LAR oraz terapią znakowanymi izotopowo analogami somatostatyny 90Y/177Lu-DOTA-TATE uzyskano poprawę sprawności chorej o 2 stopnie w skali ECOG/WHO oraz 26-miesięczną stabilizację choroby

Magnetostatic levitation and two related linear PDEs in unbounded domains

We consider a problem occurring in a magnetostatic levitation. The problem leads to a linear PDE in a strip. In engineering literature a particular solution is obtained. Such a solution enables one to compute lift and drag forces of the levitating object. It is in agreement with the experiment. We show that such a solution is unique in a class of bounded regular functions. Moreover, as a byproduct, we obtain nonstandard uniqueness results in two linear PDEs in unbounded domains. One of them is an Eigenvalue problem for the Laplacian in the strip in the nonstandard class of functions

Roux-en-Y gastric bypass in a patient with situs inversus totalis – a case report

We report a case of a Roux-en-Y gastric bypass (RYGB) in a morbidly obese patient with situs inversus totalis. Currentexperience with bariatric surgery in patients with situs inversus totalis shows that they can be operated on safely. Theopen approach in this case of a difficult anatomy may be beneficial and safer for the patient. The technique itselfrequires only minor modifications. The results of bariatric surgery in terms of weight loss are comparable to thegeneral population of morbidly obese patients after RYGB
