Abstract
We report on a case of a 19-year-old female patient with acute promyelocytic leukemia suffering from febrile monarthitis of the right knee during neutropenia after consolidation chemotherapy caused by Geotrichum capitatum. Apparently this infection occurred due to a hematological reactivation since the patient had already developed Geotrichum capitatum fungemia during induction therapy. Under antimycotic therapy with voriconazole, flucytosine, and caspofungin as well as after two arthroscopic synovectomies with cleansing of the right knee, the infection could be controlled and the full clinical function of the knee joint could be preserved.

Abstract
Leptin is mainly synthesized and secreted by fat cells in proportion to adipose tissue mass. Under physiological conditions, this hormone reduces food intake and increases thermogenesis through interactions with neurons in the central nervous system. However, transport of leptin into the central nervous system via the blood-brain barrier is saturable, and in obesity the feedback signal to the brain is markedly insufficient. In recent experiments we have shown, that intranasal (i.n.) delivery of leptin reduces food intake in rats. The aim of the present study was to explore the distribution of i.n. delivered leptin within brain, blood, and peripheral tissues. Application of [(125)I]leptin (0.03, 0.1, and 0.2 mg/kg) into male Wistar rats' nares (n = 8 per group) leads to supraphysiological brain leptin concentrations 30 min after application, with contents in the hypothalamus (7.3 +/- 2.6, 5.9 +/- 1.6, and 13.8 +/- 5.7 ng/g; P = 0.023; F = 6.157) being significantly higher than the brain average (1.2 +/- 0.2, 3.9 +/- 1.0, and 6.0 +/- 1.9 ng/g). In contrast, contents in the occipital/entorhinal cortex were lower than the brain average, indicating a minor participation of the transport via cerebrospinal fluid, which would have favored cerebrospinal fluid-exposed surfaces. In experiments employing the application of unlabeled leptin administered iv, we were able to show that excess blood leptin does not diminish brain uptake of i.n. leptin (as indicated by [(125)I]leptin), supporting a direct transport from nose to brain by circumvention of the blood-brain barrier. This study thus clearly demonstrates a rapid and highly effective transport of leptin from nose to brain.

Abstract
Intrahepatic transplantation of ovarian fragments in ovariectomized rats results in morphological abnormalities. The liver acini draining blood from ovarian grafts show alterations resembling chemically induced amphophilic hepatocellular preneoplasias. We investigated the long-term development of these estrogen-induced foci of altered hepatocytes (FAH). We divided 451 Lewis rats into one main group (MG) and 11 (7 female, 4 male) control groups and observed them for up to 30 months. MG animals were ovariectomized and received ovarian transplants into the right liver part. Different combinations of castration, transplantation of ovarian or testicular fragments, and administration of antiestrogenic toremifene were used in controls. In the MG, transplants showed signs of gonadotropic stimulation, and estrogen levels were strongly increased in the downstream liver acini. After 6 and 12 months, FAH developed in hepatocytes downstream of the transplants. After 18 months, 27% of the MG animals showed transformation of FAH into hepatocellular adenomas; this figure increased to 42% after 24 months (8/19), significantly outnumbering four spontaneous adenomas that developed between 18 and 30 months in 258 control animals. Hepatocellular carcinoma (HCC) appeared only in the MG. At 24 and 30 months, 18 HCCs developed; thus, 78% of MG animals showed at least one carcinoma. Administration of toremifene in ovariectomized and transplanted animals completely prevented hepatocarcinogenesis. Testicular grafts showed no influence on liver tissue. In conclusion, initially adaptive but preneoplastic alterations in hepatocytes downstream of intrahepatically transplanted ovarian fragments may transform into HCC, indicating a strong hepatocarcinogenic potential of high local levels of endogenous estrogens in the rat liver.

Abstract
AIM Despite the evolution in surgical technique, the biliary anastomosis remains the technical Achilles' heel of liver transplantation, especially in living donor liver transplantation. Interventional radiology or endoscopic procedures constitute the most common options to treat complications from the biliary anastomosis. We report a novel technique to prevent biliary complications following the transplant. METHODS During the donor procedure a wire guide was introduced in the severed duct, left or right, in retrograde fashion. The liver surface was then perforated and the wire guide exposed. A 4F catheter was then attached to the wire guide and pulled into the bile duct passing through the end-to-end duct-to-duct anastomosis or hepaticojejunostomy. RESULTS This technique was performed in six living donor grafts: one right lobe, two left lobes, and three left lateral segments. All patients had no complications from the stent placement, biliary strictures, or leaks. One developed a hepatic artery thrombosis on the posttransplant day 14 with no major biliary complications.

Abstract
Commercial Coenzyme Q10 (CoQ10, ubiquinone) formulations are often of poor intestinal absorption. We investigated the bioavailability of DSM Nutritional Products Ltd. (Kaiseraugst, Switzerland) CoQ10 10% TG/P (all-Q), a new tablet-grade formulation, with CoQ10 Q-Gel Softsules based on the Bio-Solv technology (Tishcon Corp., Salisbury, MD; marketed by Epic4Health, Smithtown, NY) and Q-SorB (Nature's Bounty, Bohemia, NY). Twelve healthy male subjects participated in a randomized, three-period crossover bioequivalence study. Plasma CoQ10 was determined from pre-dose until +36 hours. To compare bioavailability, corrected maximum concentration (Cmax) and area under the curve from 0 to +14 hours [AUC(0-14 h)] were assessed and tested for bioequivalence. The bioequivalence ranges of 0.8-1.25 hour x microg/mL for AUC(0-14 h) and 0.75-1.33 microg/mL for Cmax were applied. In summary, the kinetic profiles of all CoQ10 preparations revealed a one-peak plasma concentration-time course. Highest Cmax values were seen after Q-Gel application, whereas time to Cmax was nearly identical across all treatments. The AUC(0-14 h) values were highest for Q-Gel, narrowly followed by all-Q. The tests for bioequivalence showed a bioequivalence between Q-Gel and all-Q, and both preparations were found to have better bioavailability properties than Q-SorB. Although all-Q and Q-Gel have equivalent bioavailability properties, all-Q can be directly used in tablets, while this is not the case for Q-Gel or other similar forms.

Abstract
A 72-year old patient was initially misdiagnosed with allergic vasculitis. He rapidly developed petechiae and mucosal bleeding. There were no other abnormal physical findings and the patient was otherwise in good physical condition. There was no history of trauma or infectious disease. The patient's complete blood count showed a marked thrombocytopenia of 2000/nl. A bone marrow biopsy confirmed the initial diagnosis of idiopathic thrombocytopenic purpura (ITP). The number of thrombocytes increased and the skin lesions resolved shortly after the patient was put on oral prednisone. This case emphasizes the importance of dermatologic symptoms in diagnosing severe systemic disease.
