A classical pp-wave is a four-dimensional Lorentzian spacetime which admits a nonvanishing parallel spinor field; here the connection is assumed to be Levi-Civita. We generalize this definition to metric compatible spacetimes with torsion and describe basic properties of such spacetimes. We use our generalized pp-waves for constructing new explicit vacuum solutions of quadratic metric-affine gravity.

A compared, 12 week, placebo controlled study, with fixed dose, outpatient study of patients diagnosed with panic disorder with and without agoraphobia according to ICD-10, was conducted to evaluate the efficacy and safety of sertraline and alprazolam. The study included 40 patients, divided in two groups. We evaluated number of ICD-10-defined panic attacks, agoraphobia and anticipatory anxiety. All patients were aged 18 year and older and were randomized to either sertraline or alprazolam. Sertraline applied in fixed doses of 20 mg/day and alprazolam in doses 1-1,5 mg/day significantly reduced the frequency of panic attacks in panic disorder patients, reduced symptoms of agoraphobia and anticipatory anxiety.

Sore shoulder or shoulder region is frequently encountered in general population. According to reference data prevalence ranges between 15 and 20% in 40-45 age group. A weak bone support enables extensive excursions of this joint and simultaneously reduces its stability. We analyzed successfulness of sore shoulder treatment in a sample of 1115 patients treated in the Center for physical medicine and rehabilitation between 1996 and 2004. All the patients reported to the Center either in acute phase or in the phase of chronic state exacerbation, with limited function that was graded on the scale 0 to 5. Type and kind of sore shoulder cause was determined by clinical examination and, where needed, by X-ray. Of the total number of cases, 33 patients did not report for follow up examination, 166 patients were forwarded to other physical therapy centers for treatment so the final analysis included 916 patients (82%) whose treatment success was evaluated on the scale 0 to 5. In 659 (58%) patients the inflammation of musculus biceps long tendon was identified as a cause of sore shoulder. The least frequent cause was the blow syndrome (impingement)--20 (2%). In 666 patients (73%) the problem was resolved by local instillation of depo corticosteroids (Betamethason 7 mg) so the physical treatment was not required.

Gentamicin is still widely used in clinical practice in spite of its renal toxicity. The role of nitric oxide (NO) in that process is not completely elucidated. The aim of this study was to investigate the relationship between plasma level of NO and the histopathological changes of kidney in acute tubular necrosis (ATN) induced by gentamicin in rats. Study was carried out in Albino-Wistar rats, both sexes (n=16), average body weight 200-250 g. divided in two equal groups: control and gentamicin group. The control group was injected with 0.9% NaCl i.p. and gentamicin group was injected with gentamicin in the dose of 80 mg/kg/day i.p. in a period of 5 consecutive days. NO plasma level was determined by the production of nitrates and nitrites using classical colorimetrical Griess reaction. Kidney specimens were stained with hematoxylin-eosin (H-E) and Periodic acid-Schiff (PAS) stain. Semiquantitative histological analysis was used for the evaluation of the level of kidney damage. Both, the plasma NO level and the level of kidney damage were statistically higher in rats with gentamicin-induced ATN in comparison to the control group. In spite of that the correlation between plasma NO level and the level of kidney damage was not found. The rise of plasma level NO in gentamicin induced ATN in rats could possibly indicate on the role of NO in renal damage caused by gentamicin.

In this paper we have reviewed the position of desmopressin in the treatment of diabetes insipidus. Desmopressin is a synthetic analog of vasopressin, with more pronounced antidiuretic effect. It is treatment of choice in substitution therapy of diabetes insipidus. Its application before sleeping time can reduce nocturnal enuresis, so it has a place in the treatment of enuresis nocturna. Antidiuretic effect of desmopressin is the result of agonistic effect on V2 receptors in the renal tubules. The efficacy and safety of desmopressin in mentioned indications was confirmed in clinical studies.

This study investigated mortality rate of lungs carcinoma in professional vineyard sprayers. Clinical investigation was performed in 187 professional vineyard sprayers who had been exposed to the inhalation of the particles of Bordeaux mixture for 24 years on average. Bordeaux Mixture is used for prevention against mildew attacking vineyards. The control group was composed of 187 inhabitants of the same area who did not have any contact with the mentioned substance. A cytological investigation of the sputum specimens obtained from 104 tested inhabitants was performed. The sputum specimens were stained with standard haematoxylin-eosin method and also with special method (rubeanic acid) to prove the incidence of copper granules in macrophages. The findings show a considerable statistical difference in the frequency of occurrence of lungs carcinoma between the group of vineyard sprayers smokers and the control group (X2=4.77,p<0.01). The risk of lungs carcinoma in the vineyard sprayers was three times higher compared to the risk of smokers in the control group, with a statistical probability of 95% in the scope from 1.16<RR<7.78. Mortality risk of lungs carcinoma in the professional vineyard sprayers is significantly higher (p<0.01) compared to the risk in the control group.

Comparative researches of borderline between telencephalon neuroepithelium and its surrounding mesenchyme in successive early developing stages lack in literature. The aim of this investigation was to carry out systematic morphologic and stereologic analyses of rat telencephalon in early developmental stages. We analysed semithin (1 microm) serial sections of rat embryonic brain from the 12th (E12) to the 15th (E15) day of gestation. The surface densities (SV) of an external mesenchymal surface, an internal mesenchymal surface and a neuroepithelial (ventricular) surface were examined stereologically and compared. The surface density of the external mesenchymal surface was the biggest at E12 (4,05 mm-1) and the least at E15 (1,87 mm-1)-p<0,0005. The surface density of the internal mesenchymal surface was the biggest at E12 (4,02 mm-1) and the least at E15 (2,69 mm-1)-p<0,0005. The surface density of the internal neuroepithelial surface was the biggest at E12 (3,31 mm-1) and the least at E15 (2,01 mm-1)-p<<0,0005. Our stereological examines give objective numerical proof of significant morphogenetic changes in telencephalon shape described by morphologic analyses. The major advantage of stereological methods is the possibility to carry out the estimation procedures in specified, well-defined brain regions or layers.

Analysis of a cerebro-vascular insult hospitalised cases from West Herzegovina Canton as a retrospective epidemiological study was done in Clinical hospital Mostar for the period from 1998 to 2002. The major source of data was medical documentation of this hospital, the only hospital for the treatment of 88,257 inhabitants from this Canton. The study included a total of 393 cerebro-vascular insult cases from this Canton treated in the Clinical hospital Mostar. Among them 189 (48.1%) were male patients, while 204 (51.9%) cases were female. The majority of the cases were above 50 years of life. Majority of treated female patients were older then 65, while among male patients the majority were between 50 and 65 years old. The least number of cases was under 50 years in both groups. During the same period risk factors research for entire FBiH was performed on the sample of 2,750 national insurance holders. Out of them 1.7% was found to suffer of cerebro vascular insult.
