Is induction of labour by Propess(®) safe? A comparison of midwife-led versus obstetrician-led labour management.

This retrospective study compared maternal and fetal outcomes after labour induction, using a dinoprostone vaginal pessary (Propess(®)) in midwife-led and obstetrician-led labour management. Labour induction outcomes, delivery mode and rates of admission to the neonatal intensive care unit were compared. A total of 405 women, 40.5% (n = 164) from midwife-led units and 59.5% (n = 241) from an obstetrician-led unit, participated. There was no statistically significant difference between the two groups in caesarean section rate or neonatal intensive care unit admission rates (p = 0.789 and 0.769, respectively). Non-reassuring fetal non-stress test and uterine hyperstimulation risks were higher in the obstetrician-led unit (p = 0.003 and 0.001, respectively, and odds ratio (OR) 0.165, 95% CI: 0.117-0.232 and OR 0.218, 95% CI: 0.078-0.611, respectively). Postpartum blood transfusion rate was higher in the midwife-led units (p = 0.002, OR 8.082, 95% CI: 1.879-39.292). Labour induction with Propess(®) is safe during both midwife-led and obstetrician-led labour management.

Effects of hot air and freeze drying methods on antioxidant activity, colour and some nutritional characteristics of strawberry tree (Arbutus unedo L) fruit.

Antioxidant activity, colour and some nutritional properties of hot air and freeze-dried strawberry tree (Arbutus unedo L.) fruits were investigated. Additionally, the effects of two pre-treatments, namely ethyl oleate and water blanching, were compared in terms of drying characteristics. For determination of antioxidant activities in ethanol extracts, two different analytical methods were used: 1,1-diphenyl-2-picrylhydrazyl scavenging activity and ß-carotene bleaching activity. As a result, the ethyl oleate pre-treatment shortened the drying time by hot air method and gave a higher 1,1-diphenyl-2-picrylhydrazyl scavenging activity (82.16 ± 0.34%), total phenolic content (7.62 ± 1.09 µg GAE/g extract), ascorbic acid content (236.93 ± 20.14 mg/100 g), besides hydromethylfurfural was not observed. Freeze-dried fruits exhibited higher ascorbic acid content (368.63 ± 17.16 mg/100 g) than those fresh fruits (231.33 ± 19.51 mg/100 g) and nearly 1,1-diphenyl-2-picrylhydrazyl activity (93.52 ± 0.41 %) to fresh fruits (94.03 ± 1.18%). Colour characteristics, sugar content and mineral contents of fruits were significantly affected by pre-treatments and drying methods (p < 0.05). It is concluded that the drying of strawberry tree fruits should bring a valuable and attractive foodstuff to food industry due to the rich nutritional components, antioxidant activity and colour. Another conclusion from this study is that the freeze-drying is the best drying method to keep the nutritional value, antioxidant activity and sensory properties of fruits.

Phenolic compounds of Sideritis ozturkii and their in vivo anti-inflammatory and antinociceptive activities.

Acetone extract from aerial parts of Sideritis ozturkii Aytaç & Aksoy and its fractions were investigated for its in vivo anti-inflammatory and antinociceptive activities. For the anti-inflammatory activity assessment, carrageenan-induced hind paw edema and for the antinociceptive activity, p-benzoquinone-induced abdominal constriction tests were used. Acetone extract of the plant and its phenolic fraction were found to possess significant inhibitory activity on these in vivo models in mice. Ozturkoside A (chrysoeriol 7-O-[2'''-O-caffeoyl-6'''-O-acetyl-beta-d-glucopyranosyl-(1-->2)-beta-d-glucopyranoside]); ozturkoside B (chrysoeriol 7-O-[2'''-O-caffeoyl-beta-d-glucopyranosyl-(1-->2)-beta-d-glucopyranoside]); and ozturkoside C (chrysoeriol 7-O-[2'''-O-p-coumaroyl-6'''-O-acetyl-beta-d-glucopyranosyl-(1-->2)-beta-d-glucopyranoside]) were isolated from the active phenolic fraction. The structures of isolated compounds were elucidated by spectroscopic techniques (UV, IR, 1D- and 2D-NMR, MS). Ozturkoside C showed notable antinociceptive and anti-inflammatory activities without inducing any apparent acute toxicity or gastric damage. Although the activity of ozturkosides A and B were found insignificant in statistical analysis, some inhibitory effect was observed. Accordingly, it is suggested that these components in phenolic fraction might possibly share the antinociceptive and anti-inflammatory activities together.

Bilateral shoulder fracture dislocations and radiculopathies secondary to electrical injury (a case report).

INTRODUCTION: In this report a case of bilateral shoulder fracture dislocations and C5 radiculopathy developed after an electrical injury is presented. CASE: A 29 year-old male patient referred to our hospital with complaints of inability to raise his hands overhead starting 3 months ago after an electrical injury. The first physical examination revealed loss of strength (3/5) in deltoid muscles bilaterally, bilateral shoulder fracture dislocations and C5 radiculopathies. An open reduction and internal fixation (using K wire, cortical screw) procedure was applied for the right side in the Department of Orthopedics. Postoperatively active (A) and passive (P) ranges of motion (ROMs) were restricted extremely in the right and left shoulder respectively. Since applications of 15 sessions of electrical stimulation for deltoid muscle and physical treatment for both shoulders failed to achieve satisfactory ROMs, K wire extraction was instituted with resultant increase in the right shoulder A/P ROMs after 10 sessions of physical therapy postoperatively. At the last examination which was 18 months after the injury, ROMs of the right shoulder were increased, but not normal. CONCLUSION: It must be remembered that in electrical injury, fractures and dislocations might occur in affected sites without any evidence of trauma with associated neurologic complications, and that these cases must be promptly detected and managed without any delay.

Screening the antioxidant and antimicrobial properties of the lichens Parmelia saxatilis, Platismatia glauca, Ramalina pollinaria, Ramalina polymorpha and Umbilicaria nylanderiana.

The aim of this study is to investigate in vitro antimicrobial and antioxidant activities of the methanol extracts of Parmelia saxatilis (L) Ach., Platismatia glauca (L.) W.L. Club. & C.F. Culb., Ramalina pollinaria (Wesstr.) Ach., Ramalina polymorpha (Liljeblad) Ach. and Umbilicaria nylanderiana (Zahlbr.) H. Magn. Antioxidant activity was evaluated by two separate methods: scavenging of free radical DPPH and the inhibition of linoleic acid oxidation. Extracts of Parmelia saxatilis, Platismatia glauca., Ramalina pollinaria and Ramalina polymorpha did not exert any activity in both assays, whereas those of Umbilicaria nylanderiana provided 50% inhibition at 400.2 microg/ml concentration in the former and gave 53% inhibition at 2g/l concentration. Total phenolic constituents of extracts from lichen species tested (P. saxatilis, P. glauca, R. pollinaria, R. polymorpha and U. nylanderiana) were 1.0% (w/w), 1.1% (w/w), 1.0% (w/w), 0.8% (w/w) and (3.0% w/w), respectively (as gallic acid equivalent); implying that the observed activity could be related to the amount of polar phenolics. Extracts were also found to possess antimicrobial activity against some test bacteria and fungi and yeast.

Molecular characterisation of Xanthomonas strains isolated from aroids in Mauritius.

Mauritius is one of the largest world producers of Anthurium cut flowers but outbreaks of bacterial blight have never been reported on the island. This work was about the characterisation and identification of bacterial strains isolated from Anthurium andreanum, Dieffenbachia maculata and Aglaonema simplex in Mauritius. Fifteen strains, that showed the morphological properties of Xanthomonas on conventional media, were tested on two semi-selective media (Esculin-trehalose and cellobiose-starch). ELISA tests using a panel of monoclonal antibodies were carried out and three out of 15 strains reacted with a Xanthomonas-specific monoclonal antibody (MAb XII). Analysis using four sets of ribosomal primers revealed that the same three Mauritius strains shared conserved PCR products with reference xanthomonads including virulent strains of Xanthomonas axonopodis pv. dieffenbachiae (Xad). BIOLOG tests and the Sherlock Microbial Identification system (MIDI) identified these three new strains at the species level as X. axonopodis. The complementary tests that were carried out clearly confirmed that the three strains are xanthomonads and, moreover, a DNA probe which showed specificity to Xad strains suggested that the three Mauritius strains are non-virulent forms of the pathogen causing Anthurium blight.

Protracted febrile myalgia of familial Mediterranean fever.

Protracted febrile myalgia (PFM) includes severe myalgia of the upper and lower extermities accompanied by fever lasting up to 6 weeks, an elevated erythrocyte sedimentation rate and leucucytosis. We report a 13-year-old girl with PFM, and discuss the magnetic resonance imaging findings of the involved calf muscles. To our knowledge these are the only images of the pathology in the literature.

Antimicrobial effects of Quercus ilex L. extract.

The antimicrobial activities of the methanol extract of Quercus ilex L. (Pirnal oak) leaves were tested in vitro against a wide range of human and plant-associated microorganisms. A total of 132 microbial organisms belonging to 55 bacteria and five fungi and yeast species were studied using a disc-diffusion method and microdilution assays. The results were evaluated as inhibition zones around the disc impregnated with Q. ilex extract at a concentration of 300 micro L/mL. The results showed that Q. ilex did not have any antifungal activities against Alterneria alternata, Aspergillus flavus, Fusarium oxysporum, Penicillum spp., whereas there were inhibition effects on the growth of all Candida albicans isolates. In total 97 bacterial strains (74%) were found to be resistant to Q. ilex extract. The remaining 35 (27%) strains of seven different bacteria genera including Brucella, Bacillus, Enterobacter, Neisseria, Pseudomonas and Escherichia were susceptible to the extract tested. The minimum inhibitory concentrations (MIC) of the extract ranged from 125 to 500 micro L/mL. These results suggest that Q. ilex possesses compounds with antibacterial and anticandidal properties.

Evaluation of antimicrobial activities of Satureja hortensis L.

The present study was designated to evaluate the antimicrobial activities of methonol and hexane extracts of Satureja hortensis L. which is an annual herb used as traditional folk medicine in Eastern Anatolia region of Turkey for the treatment of different infectious diseases and disorders. The antimicrobial activities of the extracts against 147 laboratory strains belong to 55 bacterial species, and 31 isolates of 1 yeast and 4 fungi species were tested by using disc diffusion assay. The results showed that hexane extract of Satureja hortensis had no antifungal, but antibacterial activity against four strains of three Bacillus species whereas methanol extract of Satureja hortensis had both anticandidal and antibacterial effects. It inhibited the growth of 23 strains of 11 bacterial species and 6 isolates of Candida albicans, at the concentration of 300microg/ml. Satureja hortensis did not show antimicrobial activity against the remaining microorganisms (83%) tested including most and all of the clinic and plant pathogenic microorganisms, respectively. Methanol extract showed stronger and broader spectrum of antimicrobial activity as compared to hexane extract.

In vitro antibacterial, antifungal, and antioxidant activities of the essential oil and methanol extracts of herbal parts and callus cultures of Satureja hortensis L.

The present study was designated to evaluate the antimicrobial and antioxidant activities of the essential oil, obtained by using a Clevenger distillation apparatus, water soluble (polar) and water insoluble (nonpolar) subfractions of the methanol extracts from aerial parts of Satureja hortensis L. plants, and methanol extract from calli established from the seeds using Gamborg's B5 basal media supplemented with indole-3-butyric acid (1.0 ppm), 6-benzylaminopurine (N(6)-benzyladenine) (1.0 ppm), and sucrose (2.5%). The antimicrobial test results showed that the essential oil of S. hortensis had great potential antimicrobial activities against all 23 bacteria and 15 fungi and yeast species tested. In contrast, the methanol extract from callus cultures and water soluble subfraction of the methanol extract did not show antimicrobial activities, but the nonpolar subfraction had antibacterial activity against only five out of 23 bacterial species, which were Bacillus subtilis, Enterococcus fecalis, Pseudomonas aeruginosa, Salmonella enteritidis, and Streptococcus pyogenes. Antioxidant studies suggested that the polar subfractions of the methanol extract of intact plant and methanol extract of callus cultures were able to reduce the stable free radical 2,2-diphenyl-1-picrylhydrazyl to the yellow-colored diphenylpicrylhydrazine. In this assay, the strongest effect was observed for the tissue culture extract, with an IC(50) value of 23.76 +/- 0.80 microgram/mL, which could be compared with the synthetic antioxidant agent butylated hydroxytoluene. On the other hand, linoleic acid oxidation was 95% inhibited in the presence of the essential oil while the inhibition was 90% with the chloroform subfraction of the intact plant. The chemical composition of a hydrodistilled essential oil of S. hortensis was analyzed by gas chromatography (GC)/flame ionization detection (FID) and a GC-mass spectrometry system. A total 22 constituents representing 99.9% of the essential oil were identified by GC-FID analaysis. Thymol (29.0%), carvacrol (26.5%), gamma-terpinene (22.6%), and p-cymene (9.3%) were the main components.

The effect of PUVA treatment on sister chromatid exchange (SCE) values in psoriasis vulgaris patients.

BACKGROUND: Psoralen+ultraviolet A (UVA) (PUVA) is used successfully in the treatment of several skin diseases including psoriasis. PUVA has been reported to cause skin cancers, especially when used in high doses. In vivo and in vitro effects of different mutagens and carcinogens on DNA may be detected by sister chromatid exchange (SCE). OBJECTIVE: To investigate the mutagenic effects of different PUVA doses on DNA with SCE analysis. MATERIALS AND METHODS: Forty-two psoriasis patients under PUVA treatment were included in the study as the study group. The control group consisted of 22 psoriasis patients who did not receive PUVA treatment. The study group was divided into three groups according to PUVA doses. SCE/cell values were compared in the study and control groups and in the three dose-dependent groups of the study group. RESULTS: Mean SCE/cell values of the three dose-dependent patient groups were significantly higher than the control group (p<0.001), whereas there was not a statistically significant difference in themselves. CONCLUSION: PUVA treatment seemed to increase SCE values; however, there was not a correlation between PUVA doses and SCE frequencies.

Antimicrobial activity of aqueous and methanol extracts of Juniperus oxycedrus L.

Aqueous and methanol extracts of the leaves of Juniperus oxycedrus were investigated for their in vitro antimicrobial properties. The plant was collected from Pelitli Village of Gebze, Kocaeli, in the Marmara region of Turkey. Juniperus oxycedrus is widely used as traditional folk medicine in Turkey for treatment of different infectious diseases. The antimicrobial activity of the extracts against 143 laboratory strains belonging to 56 bacterial species, and 31 isolates of 5 fungi species were evaluated based on the inhibition zone using the disc-diffusion assay, minimal inhibition concentration (MIC) and minimal bactericidal concentration (MBC) values. The aqueous extract of J. oxycedrus had no antimicrobial effect against the test microorganisms whereas the methanol extract had inhibitory effects on the growth of 57 strains of 24 bacterial species in the genera of Acinetobacter, Bacillus, Brevundimonas, Brucella, Enterobacter, Escherichia, Micrococcus, Pseudomonas, Staphylococcus, and Xanthomonas. In addition 11 Candida albicans isolates at a concentration of 31.25-250 micro g/ml were also inhibited.
