Ethnopharmacological survey of medicinal plants in Maden (Elazig-Turkey)

Aim of the study

This study aimed to identify wild plants collected for medical purposes by the local people of Maden County, located in the Eastern Anatolia Region of Turkey, and to establish the uses and local names of these plants.

Materials and methods

Field study was carried out over a period of approximately 2 years (2008-2010). During this period, 131 vascular plant specimens were collected. Demographic characteristics of participants, local plant names, utilized parts and preparation methods of the plants were investigated and recorded. In the scope of the study, the plant species were collected; herbarium materials were prepared; and the specimens were entitled. The Zazas are of the major ethnic group in the region. In addition, the relative importance value of the species was determined and informant consensus factor (FIC) was calculated for the medicinal plants included in the study.

Results

A total of 88 medical plants belonging to 41 families were identified in the region. 4 plants out of 88 were recorded to be used for curative purposes for the first time. It was determined that the local names of four different kinds of plants used in Maden were same as the different kinds of plants used in different regions. The most encountered medicinal plant families were Urticaceae (>21%), Rosaceae and Lamiaceae (>17% of use-reports), Asteraceae (>13%), Fabaceae (>8%), Brassicaceae (>7%), Poaceae (>4%); the most common preparations were decoction and infusion. Mentha spicata L. subsp. spicata, Rosa canina L. and Urtica dioica L. was the plants most used by the local people. Anthemis wiedemanniana Fisch. and Mey., Bunium paucifolium DC. var. brevipes (Freyn & Sint.) Hedge & Lam., Tchihatchewia isatidea Boiss., Thymus haussknechtii Velen. were found to be the endemic plants used for medical purposes in Maden, Turkey. The medicinal uses of Bunium paucifolium DC. var. brevipes (Freyn & Sint.) Hedge & Lam., Hippophae rhamnoides L. subsp. caucasica Roussi, Gladiolus atroviolaceus Boiss., Ixiolirion tataricum (Pallas) Herbert subsp. montanum (Labill.) Takht. were recorded for the first time.

Conclusion

Herbal treatment has become a tradition for the residents of the study region. These plants, which are used in the treatment of many diseases. Comparison of the data obtained in this study from the plants growing in Maden with the experimental data obtained in the previous laboratory studies proved most of the ethnobotanical usages. Literature review showed that curative plants of Maden are used in different parts of the world in the treatment of the same or similar diseases. If a plant is used to treat the same disease in different places across the world then its pharmacologic effect could be accepted. It would be beneficial to conduct pharmacologic studies on such plants. These plants, used in the treatment of many different diseases, are in this region at abundant amounts. Drying enabled local people to use medicinal plants during all seasons of the year. This study identified not only the wild plants collected for medical purposes by local people of Maden County in the Eastern Anatolia Region, but also the uses and local names of these plants. It is tried to generate a source for persons studying in ethnobotany, pharmacology and chemistry sciences by comparing knowledge gained from traditionally used herbs with previous laboratory studies.     

Induction chemotherapy with triweekly docetaxel and cisplatin followed by concomitant chemoradiotherapy with or without surgery in stage III non-small-cell lung cancer: a phase II study

Background

The main goal of this study was to evaluate the feasibility and effectivity of triweekly docetaxel/cisplatin followed by weekly docetaxel/cisplatin concomitantly with radiotherapy with or without surgery in locally advanced non–small-cell lung cancer (NSCLC) patients.

Materials and Methods

Thirty five patients with locally advanced NSCLC were enrolled. Combination chemotherapy with triweekly docetaxel/cisplatin (75 mg/m²) was administered as induction regimen. After induction chemotherapy, patients were evaluated for surgery if their disease subsequently downstaged. Six cycles of weekly docetaxel/cisplatin (20 mg/m²) concurrently with radiotherapy up to a 60 Gy were administered after induction chemotherapy with or without surgery. Response, toxicity, time-to-progression and overall survival were evaluated.

Results

Twelve patients with stage IIIA-N2 and 23 patients with stage IIIB-T4N0-2 were evaluated (median age, 54 years). After 94 cycles of induction chemotherapy, partial response was achieved in 20 patients, 9 patients had stable disease and six had progressive disease. After overall treatment, 6 patients achieved complete response, 19 patients had partial response, 8 patients had progressive disease, and 2 patients had stable disease. Two patients experienced grade 3-4 pulmonary toxicity and 1 patient experienced grade 3 esophageal toxicity. Six patients underwent surgery. Median overall survival for all patients was 15 months and time-to-progression was 13 months with a median follow-up of 22 months.

Conclusion

Triweekly docetaxel plus cisplatin followed by weekly docetaxel plus cisplatin concomitantly with radiotherapy is effective and feasible and seems to be an alternative option for patients who have locally advanced NSCLC. Surgery may provide additional benefit for patients whose disease adequately downstaged after induction chemotherapy.     

Factors Contributing to Regular Smoking in Adolescents in Turkey

PURPOSE: The objectives of this study were to determine the levels of lifetime cigarette use, daily use, and current use among young people (aged 15-19 years) and to examine the risk factors contributing to regular smoking. METHODS: The number of students was determined proportionately to the numbers of students in all the high schools in the province of Trabzon in Turkey. The data were gathered using the questionnaire method. A total of 4666 students participated in the study. The chi-square test and logistic regression analysis were used in data analysis. RESULTS: Of the 4666 students who took part in the study, the level of lifetime cigarette use was 38.2% (n = 1796), that of lifetime daily cigarette use was 10.5% (n = 491), and that of current cigarette use was 9.5% (n = 447). Male students (P < .0005), those whose mothers were smokers (P < .0005), those whose fathers smoked (P = .005), those whose siblings smoked (P<.0005), those whose friends smoked (P < .0005), those whose teachers smoked (P = .001), and low achievers in school (P < .0005) stated that they significantly smoked on a more regular basis. According to the results of the logistic regression analysis, the following risk factors were statistically significant: male students smoked 3.02 times (95% CI 2.20-4.16) more than females, those whose mothers were smokers smoked 1.57 times (95% CI 1.09-2.28) more than those whose mothers were not, those whose friends were smokers smoked 2.42 times (95% CI 1.73-3.39) more than those whose friends were non-smokers, poor achievers in school smoked 2.62 times (95% CI 1.97-3.49) more than high achievers, and those without poor grades smoked 1.75 times more (95% CI 1.23-2.40), the risk rising 1.06 times (95% CI 1.01-1.11) with earlier age at first experimentation. The risk of daily cigarette use was observed to decline by 0.91 times (95% CI 0.84-0.98) with increasing numbers of siblings. CONCLUSION: Effective smoking prevention programs should take into account the dominant influence of peer groups in the onset and continuation of smoking.     

Duodenal duplication cyst: a rare cause of acute pancreatitis in children

Duodenal duplication is a rare cause of acute pancreatitis in children. We report a case of acute pancreatitis in which abdominal sonography revealed an enlarged hypoechoic edematous pancreas with mildly dilated main pancreatic duct and a cystic structure with layered wall in the second part of duodenum. Abdominal CT yielded similar findings. The diagnosis of duodenal duplication was confirmed at surgery and subsequent histopathologic examination.     

Mania profile in a community sample of prepubertal children in Turkey

Background:  Mania in youth is increasingly recognized and accompanied by substantial psychiatric and psychosocial morbidity. There are no data on prepubertals in the general population and we aimed to search for mania symptoms and its clinical correlations in a community sample of prepubertal Turkish children.
Methods:  Among all children (n = 56,335) aged 7–11 in Adana, Turkey, 2,468 children (48% girls) were randomly included. Parents completed Child Behavior Checklist (CBCL) 4–18 and Parent-Young Mania Rating Scale (P-YMRS). Cut-off scores of 17 and 27 on total P-YMRS were defined as efficient (probable-mania group) and specific (mania group), respectively, for bipolar profile. We searched for clinical correlations and used logistic regression to show how well each CBCL subscale predicted the presence of mania and probable-mania, after adjusting for any demographic differences.
Results:  Parent-Young Mania Rating Scale scores were ≥17 but <27 (probable-mania) in 155 (6.3%) children and ≥27 (mania) in 32 (1.3%) children. Elevated mood, increased activity levels, and poor insight were the most frequent manic symptoms in our sample. Children with probable-mania and mania had higher scores on all CBCL subscales and the CBCL-Pediatric Bipolar Disorder (CBCL-PBD) profile (sum of attention, aggression, and anxiety/depression subscales). Logistic regression analysis revealed only thought problems on CBCL that predicted probable-mania and mania.
Conclusion:  Our study shows that mania profile is common in the community sample of Turkish prepubertal children and does not support the thought that mania is rare outside the US. We need further population-based studies that will use diagnostic interviews and multiple informants.     

Hand carriage of Candida species and risk factors in hospital personnel

The hands of healthcare workers (HCWs) are considered to be important for colonisation and infection of Candida spp. The objective of this study was to evaluate the rate of Candida carriage on the hands of the hospital personnel the potential risk factors. Samples were collected from the hands of 214 (139 female and 75 male) hospital personnel working at Duzce Medical Faculty Hospital, Duzce, Turkey. Of these, 88 were nurses, 62 resident doctors, 21 laboratory workers, 30 officers and 13 dining room personnel. The hands of all participants were tested by culture with the broth wash technique. Overall, 34.1% of the people analysed were found to harbour Candida spp. on their hands: 30.7% were nurses, 25.8% resident doctors, 28.6% laboratory workers, 84.6% dining room personnel and 43.3% officers. Candida carriage rates of the dining room personnel were higher than found in the other groups (P = 0.001). Isolated Candida species were C. parapsilosis (38.4%), C. tropicalis (26.0%), C. albicans (23.3%), C. kefyr (11.0%) and C. globosa (1.4%). Candida carriage rate was higher in the glove-using group (35.1%) than the non-glove using group (7.1%, P = 0.031). We concluded that carriage of Candida species on the hands of personnel was common especially in non-medical staff. Wearing gloves was found to be related to increased rates of Candida carriage in the nurse group. Candida parapsilosis was the most frequently colonising species that may be a predisposing condition for nosocomial infections transmitted with the hands of HCWs. Hospital personnel should be educated for regular hand washing practice for preventing Candida colonisation.     

The genotoxic effects in lymphocyte cultures of children treated with radiosynovectomy by using yttrium-90 citrate colloid

The aim of this study was to investigate the genotoxic effect on the peripheral blood lymphocytes potentially induced by yttrium-90 citrate colloid (Y-90) in children who were undergoing radiosynovectomy for hemophilic synovitis, using chromosomal aberration analysis (CA) and the micronuclei (MN) assay for detecting chromosomal aberrations, as well as the sister chromatid exchanges (SCE) technique for assessed DNA damage. MATERIALS AND METHODS: Cytogenetic analyses were undertaken in 18 boys (mean age, 14.5 +/- 2.1 years) with hemophilic synovitis who underwent radiosynovectomy with Y-90. CA, MN, and SCE were evaluated just prior to, then at 2 and 90 days following radiosynovectomy from the peripheral lymphocytes of the children. An activity of 185 MBq of Y-90 was injected into the 18 knee joints under aseptic conditions. To check the possibility of leakage from the joint and its migration within the body, the patients underwent scanning under a dual-headed gamma camera at the hours 2 and 48 following the procedure. RESULTS: The procedure was well tolerated in all the children, and there was no extra-articular activity owing to extra-articular leakage of radioactive material in whole-body imaging. The mean frequency of CA in lymphocytes determined prior to the onset of therapy (0.31 +/- 0.48/900 cells) was not significantly increased, in comparison to the control values obtained 2 (0.30 +/- 0.48/900 cells) and 90 days (0.15 +/- 0.37/900 cells) after radiosynovectomy (p = 1.0 and 0.625, respectively). We observed that MN frequency was mildly increased in lymphocytes 2 days after therapy (8.30 +/- 1.89 MN/1000 binucleated cells vs. 9.23 +/- 1.79 MN/1000 binucleated cells; p = 0.013). But there was no significant difference between the baseline and the day 90 control levels of MN (p = 0.196). In the analysis of SCE frequency, there were no significant differences between the baseline (8.11 +/- 0.77) and the control analysis performed 2 and 90 days following radiosynovectomy (8.18 +/- 0.77 and 8.07 +/- 0.74; p = 0.710 and 0.662, respectively). CONCLUSIONS: The results of this study indicated that high radiation doses are not obtained by peripheral lymphocytes of children who undergo Y-90 radiosynovectomy and, therefore, they contradict a high cancer risk.

Augmentation of venous drainage by a venous anastomosis for pedicled flaps

Recently several studies have addressed the venous problem and confirmed that venous ischemia is more injurious to tissue viability than arterial ischemia of equivalent duration. There are different methods of managing venous-compromised pedicled flaps. Between June 1996 and November 2003, our center treated two submental, five Becker, nine posterior interosseous, three distally based sural, and three colon pedicled flaps (22 flaps in total), which had venous congestion either at the time of flap elevation or immediately after inset of the flap. These cases of venous congestion were managed with an immediate additional venous anastamosis. After vein anastomosis, venous congestion reduced gradually, then improved, and finally disappeared completely in the postoperative follow-up days with all flaps surviving in their entirety. Reexploration was not required for the microsurgical venous anastomosis. In conclusion, flap necrosis resulting from venous congestion causes prolonged hospitalization, multiple debridements, and additional procedures to cover the exposed structures. Additional vein anastomosis, which is a simple, rapid, and reliable auxiliary procedure, may increase complete flap survival and lead to successful end results, both functional and cosmetic.     

Gemcitabine and cisplatin as neo-adjuvant chemotherapy for non-small cell lung cancer: a phase II study

The combination of gemcitabine and cisplatin is one of the most active chemotherapy regimens against non-small cell lung cancer (NSCLC). This study was designed to evaluate the efficacy and safety of gemcitabine combined with cisplatin in a 3-week cycle regimen for patients with operable, early stage NSCLC. Gemcitabine at a dose of 1000 mg/m(2) on days 1 and 8 of each 21-day cycle for 3 cycles, followed by cisplatin at a dose of 75 mg/m(2) on day 1 was administered to patients with previously untreated, operable, early stage (IB-IIIA) NSCLC. A total of 47 patients (46 male, mean age 56.0+/-8.0 years) who met the eligibility criteria were enrolled. The pathological complete response rate was 5.3% of operated patients and 4.3% of total patients. At visit 4, 57.1% of the patients had partial response, 38.1%, stable disease and 4.8%, progressive disease. The main toxicities - leukopenia, neutropenia and thrombocytopenia - were usually clinically asymptomatic and did not require hospitalization. Non-hematological toxicities were minimal and manageable. Disease free and 12-month overall survival rates were over 70% and 80%, respectively. This study demonstrates that the administration of gemcitabine and cisplatin combination for 3 cycles is effective and tolerable for patients with operable, early stage NSCLC. Low toxicity profile and promising survival outcome suggest that this regimen has an encouraging activity in this subset of patients.
