Serum iron levels in schizophrenic patients with or without akathisia.

The pathophysiology of akathisia still remains controversial. Iron deficiency was proposed to be an important factor in the development of akathisia. In the present study, it was aimed to compare levels of serum iron and linked variables in chronic akathisic (n=30), and non-akathisic patients (n=30) with schizophrenia and healthy controls (n=30) because of the controversy in the association of iron and akathisia. The Barnes Akathisia Scale for akathisia and Simpson-Angus Rating Scale for extrapyramidal side effects were used. Serum iron and linked variables and hematological profile of the patients and control subjects were determined. Serum iron levels were significantly lower both in akathisic and non-akathisic groups compared to the control group (P<0.001). Moreover, akathisic patients had significantly lower iron levels than non-akathisic patients (P<0.05). Total iron binding capacity was significantly higher in patients with akathisia compared to the control group (P<0.01). Although non-akathisic patients had a mild increase in total iron binding capacity, it was not statistically significant compared to the control group (P>0.05). Ferritin levels were determined to be significantly lower in both groups compared to the control group (P<0.01). In addition, there was a significant difference in ferritin levels between the patients with and without akathisia (P<0.05). In conclusion, our results support the hypothesis that an association between akathisia and iron metabolism exists.     

Pyridazines,LVII: Synthesis and Cyclocondensation Reactions of (2-Aminophenyl)-(4-pyridazinyl)-ketone,a New Diaza Isoster of 2-Aminobenzophenone

A convenient approach to the new 2-aminobenzophenone analogue 4 is reported. Condensation reactions of 4 with ortho esters or amide acetals, respectively, followed by intramolecular cyclisations were found to provide smooth access to (4-pyridazinyl)-substituted quinolines 10, 13a,b , and the quinazoline derivative 15 .     

Systemic angioendotheliomatosis of the lung

Systemic angioendotheliomatosis is a very rare malignant disease characterized by intravascular neoplastic proliferation of reticuloendothelial cells. According to the clinical features three different types of prognostic value can be distinguished: Exclusive skin involvement; Progressive skin lesions disseminating to internal organs; Aggressive and lethal type affecting primarily internal organs. Until now about 60 cases of systemic angioendotheliomatosis have been reported in the literature. Here we describe the first well-documented case with almost isolated lung involvement. The presentation of morphologic and clinical signs and differential-diagnostic considerations are followed by a critical review of the literature.     

Transjugular intrahepatic cavoportal shunt for Budd–Chiari syndrome

Budd–Chiari syndrome (BCS) is characterized by obstruction of the hepatic venous outflow tract. Therapeutic options for BCS are limited. We report a case of a 21-year-old woman with protein S and C deficiency with gross ascites. Treatment with transjugular intrahepatic portosystemic shunt (TIPS) was attempted, which revealed occluded hepatic veins, so transcaval TIPS was performed. No serious procedure-related complication occurred. After successful shunt creation, the patient's symptoms subsided and she was discharged and followed up for 6 months.     

Undiagnosed pheochromocytoma in a patient with lindau disease

Lindau disease is characterized by angioblastic lesions of the cerebellum and spinal cord. It may, rarely, be associated with pheochromocytoma. We describe the management of a patient with Lindau disease who was scheduled to undergo craniotomy for removal of a cerebellar hemangioblastoma and who developed severe hypertension following induction of anesthesia. Subsequent work up revealed a previously undiagnosed pheochromocytoma. The importance of recognizing a possible association between these two conditions is discussed.     

Characterization of Aeromonas caviae antigens which cross-react with Shigella boydii 5.

Live and boiled cells of 16 strains of Aeromonas caviae, isolated from patients with diarrhea, agglutinated with Shigella boydii 5 antiserum in a slide test. Further studies with seven selected strains showed agglutination with boiled cells in a tube test. Lipopolysaccharide antigen extracted from one of these strains cross-reacted with S. boydii 5 in enzyme-linked immunosorbent assay and immunoblot studies. Either all or the majority of the seven strains possessed properties deemed to be diarrheagenic.     

Blutlipid- und BlutglukoseverÄnderungen bei Einfach-, Mehrfach- und Wiederholungsstre\

Zusammenfassung Auf den Organismus einwirkende Stressoren, die einen gewissen Schwellenwert überschritten haben, bewirken deutliche StoffwechselverÄnderungen; diese Tatsache ist seit langem experimentell bewiesen.Wir konnten zeigen, da\ diese VerÄnderungen bei Einfach- und Mehrfachstre\ verschieden sind und da\ die StoffwechselverÄnderungen bei wiederholter Belastung offensichtlich Habituationsbzw. AdaptationsvorgÄngen unterworfen sind. Derartige stre\induzierte Stoffwechselmechanismen laufen aber für die einzelnen Blutfette und die Glukose unterschiedlich ab, was durch die verschiedenen Funktionen der einzelnen Parameter in Belastungssituationen erklÄrbar ist. Die Analyse dieser VerÄnderungen ist für die PrÄvention von stre\induzierten Stoffwechelentgleisungen von gro\er Bedeutung.Mit finanzieller Unterstützung des österreichischen Fonds zur Förderung der wissenschaftlichen Forschung     

Plasmid analysis of Shigella dysenteriae type 1 isolates obtained from widely scattered geographical locations.

Plasmid profiles and antimicrobial susceptibility patterns of 343 strains of Shigella dysenteriae type 1, obtained from 18 different geographical locations, were analyzed. Three plasmids, with molecular sizes of 140, 6, and 2 megadaltons (MDa), were present in 94, 98, and 96%, respectively, of the 343 strains isolated during either epidemic or nonepidemic periods from 1965 to 1987. In addition to these plasmids, 83% of the strains harbored a 4-MDa plasmid and 25% harbored a 20-MDa plasmid. Various plasmid profiles were observed in which the 140-, 6-, and 2-MDa plasmids occurred commonly, irrespective of the place of isolation and drug resistance pattern of the strains. Certain profiles showed significant association with drug resistance patterns. These findings suggest that three plasmids, of molecular sizes 140, 6, and 2 MDa, are unique to S. dysenteriae type 1 strains and may indicate the global spread of a pathogenic bacterial clone. Additionally, these core plasmids, plus plasmids of various other sizes, could be used to identify emerging subclones which are causing both epidemic and sporadic disease. Thus, plasmid profiles of S. dysenteriae type 1 strains can be used to monitor possible pandemic strains as well as individual epidemic strains.
