Intrasphenoidal migration of a premaxillary Kirschner wire.

OBJECTIVE: The use of Kirschner wire for the fixation of premaxilla is a well-known method in bilateral cleft lip surgery. We report a case in which the Kirschner wire of the premaxillary fixation had migrated intrasphenoidally. RESULTS AND CONCLUSIONS: The foreign body was accidentally discovered during a cephalometric analysis and was taken out surgically through an upper lip sulcus incision. Although the wire remained asymptomatic for 10 years, it constituted a potential danger for intracranial migration.     

Rhabdomyolysis as a side effect of simvastatin treatment

Myopathy and rhabdomyolysis are rare adverse effects of treatment with hydroxymethylglutaryl-coA reductase inhibitors. The risk of adverse effects is increased with the concomitant use of statin and specific drugs that can induce myopathy, in patients with liver and renal function impairment, hypothyroidism and diabetes mellitus. The clinical picture of rhabdymyolysis with acute renal failure caused by the use of simvastatin in a 54-year-old patient with diabetes mellitus and hypertension is described.     

Genetic characterization of L-Zagreb mumps vaccine strain

Eleven mumps vaccine strains, all containing live attenuated virus, have been used throughout the world. Although L-Zagreb mumps vaccine has been licensed since 1972, only its partial nucleotide sequence was previously determined (accession numbers , and ). Therefore, we sequenced the entire genome of L-Zagreb vaccine strain (Institute of Immunology Inc., Zagreb, Croatia). In order to investigate the genetic stability of the vaccine, sequences of both L-Zagreb master seed and currently produced vaccine batch were determined and no difference between them was observed. A phylogenetic analysis based on SH gene sequence has shown that L-Zagreb strain does not belong to any of established mumps genotypes and that it is most similar to old, laboratory preserved European strains (1950s-1970s). L-Zagreb nucleotide and deduced protein sequences were compared with other mumps virus sequences obtained from the GenBank. Emphasis was put on functionally important protein regions and known antigenic epitopes. The extensive comparisons of nucleotide and deduced protein sequences between L-Zagreb vaccine strain and other previously determined mumps virus sequences have shown that while the functional regions of HN, V, and L proteins are well conserved among various mumps strains, there can be a substantial amino acid difference in antigenic epitopes of all proteins and in functional regions of F protein. No molecular pattern was identified that can be used as a distinction marker between virulent and attenuated strains.     

Expression of the axon growth-related neural adhesion molecule TAG-1/axonin-1 in the adult mouse brain

 TAG-1/axonin-1 is a neuronal cell adhesion molecule of the immunoglobulin superfamily. It is predominantly expressed during neural development and has been reported to be involved in axonal growth and pathfinding. Here, the expression of TAG-1/axonin-1 was investigated anatomically in the adult mouse brain by in situ hybridization using digoxigenin-labeled cRNA probes. Low levels of TAG-1/axonin-1 could be detected in cerebellar granule cells, in tufted and mitral cells of the olfactory bulb, and in pyramidal cells of area CA1 and CA3 of the hippocampus. We suspect that the expression of TAG-1/axonin-1 in these structures of the adult brain may serve neural plasticity. Accepted: 8 September 1997     

Morphological and functional reconstruction of the mitral valve: a new annuloplastic procedure

A new method of semi-frame mitral annuloplasty is presented. The advantages of this technique are discussed in the following case reports. Although only a few selective cases were available for application of this procedure, it appears suitable for correction of mitral insufficiency.     

Cyclodextrin encapsulation of daidzein and genistein by grinding: implication on the glycosaminoglycan accumulation in mucopolysaccharidosis type II and III fibroblasts

This work aimed to investigate the potential effect of cyclodextrin encapsulation on intrinsic ability of daidzein (DAD) and genistein (GEN) to inhibit the glycosaminoglycan (GAG) synthesis in fibroblasts originating from patients with mucopolysaccharidosis (MPS), type II and III. DAD or GEN encapsulation with either 2-hydroxypropyl-β-cyclodextrin or sulphobuthylether-β-cyclodextrin were achieved by neat grinding and were characterised by thermal analysis, X-ray powder diffraction, scanning electron microscopy and solubility testing which confirmed the complexes formation with increased solubility with respect to starting compounds. Both isoflavones, as well as their co-ground cyclodextrin complexes reduced GAG levels in the fibroblasts of MPS II and MPS III patients from 54.8–77.5%, in a dose dependent manner, without any significant cytotoxic effect. Cyclodextrin encapsulation did not change the intrinsically high effect of both DAD and GEN on the GAG level reduction in the treated cells, thus could be considered as a part of combination therapies of MPS.     

Diagnostic value of screening tests in subgroups of women with recurrent pregnancy loss

Objective: To evaluate the diagnostic value of screening laboratory tests in women who had recurrent pregnancy loss (RPL).

Methods: A total of 252 women with RPL managed in our tertiary referral research and education hospital were included in the study. Risk factors recorded involved age, gravidity, parity, number of prior live births, number of pregnancy losses, and thrombophlia tests. The cases were divided into three different groups and each group was analyzed separately.

Results: There was no statistically significant difference between the first and second groups in terms of clinical and laboratory parameters (p?>?0.05). In the third group, there was a statistically significant difference among cases in terms of parity, gravidity, number of pregnancy losses, serum AT III levels, APCR, and age of the women. According to the logistic regression model, odds ratios (95% CI) were 6.116 (3.797–9.852), 5.665 (2.657–12.079), 4.763 (3.099–7.321), 4.729 (3.080–7.260), 2.820 (1.836–4.333), and 1.911 (1.232–2.965), respectively.

Conclusions: We do not recommend the screening of all women with RPL, but in women with high parity and those who had prior live birth pregnancies, increased AT III, and APCR may be diagnostic markers for subsequent pregnancy loss.
