WOS: 000381331000006, Thermal springs are important for community health since they are public places and being widespreadly used. Free-living amoeba are common in nature. Naegleria and Acanthamoeba species in particular are found in thermal springs and may cause serious health problems. At the first stage of the study, it is aimed to research the presence of Naegleria and Acanthamoeba species in thermal springs in Turkey while the second stage looks into the frequency of subtypes of these species by genotyping through molecular techniques. The results of the first stage are presented in this article. The second stage is currently in progress. This is the first research where all the thermal springs licensed in Turkey are included. The parasitological examination of 434 samples revealed that 34.1% of the samples were amoeba positive. Upon the completion of this study, the frequency of pathogen species and health risks linked to the amoeba will have been laid bare. Chlorination, FLA determination and typology should be incorporated into monitoring criteria for thermal spring water. To prevent health risks regarding amoeba, it would be beneficial to raise the awareness of users about hygienic practices and thwart health risks induced by amoeba in thermal springs.

WOS: 000231033600010, PubMed ID: 16117371, The study was carried out to determine the prevalence of parasites in three socioeconomically-different regions (Alibaba, Esentepe, and Cayboyu) of Sivas, Turkey, to determine the most accurate method for the diagnosis of taeniasis and enterobiasis, to determine the importance of household visits in primary healthcare to control parasitic diseases, and to treat intestinal parasitic diseases in those regions. Both stool specimens and cellophane tape (CT) samples were taken from 1,864 participants during 641 household visits in the three regions. The age groups included were pre-school [(0-6 year(s)], primary school (715 years), and the upper age group (16 years and above). The total prevalence of intestinal parasites in the three regions was 37.2%. Eleven intestinal parasite species were detected in both stool specimens and CT samples. Giardia intestinalis and Enterobius vermicularis were the most frequent species identified in all the three regions. Region I (Alibaba) had a higher prevalence of parasites compared to the other two regions. There was no significant difference between Region II (Esentepe) and Region III (Cayboyu) in isolation of intestinal parasites. There were statistically significant differences between the age groups when the rates of parasitic infection were compared. The highest prevalence of parasitosis was observed among the age group of 7-15 years and in the socioeconomically lowest one of the three regions. While the most accurate way of diagnosis for taeniasis was the combined usage of the CT and direct preparation methods, the CT method was the best method for the diagnosis of enterobiasis. Thus, the local administrators in cities need to pay more attention to the prevention of parasitic infections along with improvements in educational, environmental and sanitary conditions.

WOS: 000305532700005, PubMed ID: 22215196, Amebiasis is a severe illness caused by Entamoebachistolytica. The aim of this study is to evaluate the in vitro amebicidal activity of the rhizomes and aerial parts of Allium sivasicum, an endemic plant species from the flora of Turkey. Both extracts showed a time- and dose-dependent amebicidal action on the trophozoites. Among the extracts tested, rhizomes of A. sivasicum showed the strongest amebicidal effect on the trophozoites. In the presence of the rhizome extract at 2.0 mg/ml concentration, all of the trophozoites available in media have completely been killed within the 72nd hour. At 4.0 mg/ml extract concentration, all of the trophozoites available in media have completely been killed by the rhizome extract from the time of 24th hour. At 32.0 mg/ml extract concentration, 73.7% of the trophozoites were successfully killed by the extract within the first experimental hour. Aerial part extract at 4.0 mg/ml concentration completely killed the trophozoited within the 48th hour of the experimental procedure. At 8.0 mg/ml extract concentration, all of the trophozoites available in media have completely been killed by the aerial part extract from the time of 24th hour. At 32.0 mg/ml extract concentration, 67.7% of the trophozoites were successfully killed by the extract within the first experimental hour. These results suggest that the plant species evaluated here is a potential therapeutic drug for the treatment of Entamoeba infections, but it still needs to be evaluated quantitatively for determining the active phytochemicals., Research Council of Cumhuriyet University (CUBAP), Sivas-TURKEY [F-346], This study is financially supported by the Research Council of Cumhuriyet University (CUBAP), Sivas-TURKEY by the project numbered with F-346.

WOS: 000304627300011, PubMed ID: 22160280, Amoebic keratitis is difficult to treat without total efficacy in some patients because of cysts, which are less susceptible than trophozoites to the usual treatments. The aim of this study is to evaluate the in vitro amoebicidal activity of the methanolic extracts of Satureja cuneifolia and Melissa officinalis. In the presence of methanolic extracts (ranging from 1.0 to 32.0 mg/ml), numbers of the viable Acanthamoe castellanii trophozoites and cysts were decreased during the experimental process. Both extracts showed a time- and dose-dependent amoebicidal action on the trophozoites and cysts. Among the extracts tested, S. cuneifolia showed the strongest amoebicidal effect on the trophozoites and cysts. In the presence of 32 mg/ml extract, no viable trophozoites were observed within 24 h. At the same concentration value, the extract was found effective against the cysts at a rate of 46.3% within 72 h of the experimental process. At 16 mg/ml extract concentration, no viable trophozoites were also observed in the 24th hour of the experiment. At the end of the experimental process, 34.7% of the cysts were killed by the extract. M. officinalis showed moderate amoebicidal effect. At the concentration of 32 mg/ml, 44.3% and 30.0% of the trophozoites and cysts were killed by the extract, respectively. Results obtained from these concentration values were found statistically different in terms of their actions both on trophozoites and cysts (p < 0.05)., Research Council of Cumhuriyet University (CUBAP), Sivas, Turkey [F-346], This study is financially supported by the Research Council of Cumhuriyet University (CUBAP), Sivas, Turkey with the project number F-346.

The aim of the present study was to find out the number of students with enterobiasis and/or taeniasis in primary schools of Sivas. Among the 2,029 students in 6 primary schools, 316 (15.6%) were positive to Enterobius vermicularis eggs and 32 (1.6%) were positive to Taenia spp. eggs by the cellophane tape method. The egg positive rates of E. vermicularis and Taenia spp. ranged from 9.4% to 27.2% and from 0.8% to 2.6% respectively among six schools. The egg positive rate of E. vermicularis was found to be significantly different among these schools (chi2 = 31.96, P < 0.05), whereas there was no significant difference between the schools for Taenia spp. (chi2 = 4.37; P > 0.05). The rate (18.7%) of E. vermicularis in the urban slum regions was higher than the rate (11.5%) in the urban central regions (chi2 = 19.20; P < 0.05). Above results demonstrate that the egg positive rate of E. vermicularis and Taenia spp. was still prevalent among primary school children.

- Abstract
The incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing worldwide. This disease encompasses several stages, from steatosis to steatohepatitis and, eventually, to fibrosis and cirrhosis. Exposure to environmental contaminants is one of the risk factors and an increasing amount of evidence points to a role for endocrine disrupting compounds (EDCs). This study assesses the impact of selected EDCs on the formation of lipid droplets, the marker for steatosis in a hepatic model. The mechanisms underlying this effect are then explored. Ten compounds were selected according to their obesogenic properties: bisphenol A, F and S, butyl-paraben, cadmium chloride, p,p'-DDE, DBP, DEHP, PFOA and PFOS. Using a 2D or 3D model, HepaRG cells were exposed to the compounds with or without fatty acid supplementation. Then, the formation of lipid droplets was quantified by an automated fluorescence-based method. The expression of genes and proteins involved in lipid metabolism and the impact on cellular respiration was analyzed. The formation of lipid droplets, which is revealed or enhanced by oleic acid supplementation, was most effectively induced by p,p'-DDE and DEHP. Experiments employing either 2D or 3D culture conditions gave similar results. Both compounds induced the expression of PLIN2. p,p'-DDE also appears to act by decreasing in fatty acid oxidation. Some EDCs were able to induce the formation of lipid droplets, in HepaRG cells, an effect which was increased after supplementation of the cells with oleic acid. A full understanding of the mechanisms of these effects will require further investigation. The novel automated detection method described here may also be useful in the future as a regulatory test for EDC risk assessment., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

- Abstract
Melkersson-Rosenthal Syndrome (MRS) is a rare disorder consisting of a triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. It is rarely possible to observe all aspects of the classical triad at the same time, since these symptoms may appear in different times of life cycle. The most common symptom is orofacial edema. Although etiology of MRS is unclear, various factors such as infections, genetic predisposition, immune deficiency, food intolerance and stress have been held responsible. MRS is diagnosed based on clinical features. This case report describes a 39 years old male patient with recurrent swelling of the upper lip. Clinical examinations showed classical triad of MRS. The diagnosis and treatment procedures were presented with special emphasis to the clinical features of this rare condition., Competing Interests: Conflict of interest: None declared.

- Abstract
Purpose: The purpose of this retrospective study was to compare the performance of cone-beam computed tomography (CBCT) and panoramic radiography in detecting the presence and location of maxillary sinus septa., Materials and Methods: This study included radiographic examination of 104 maxillary sinuses of 52 individuals (26 females, 50% and 26 males, 50%) whose panoramic radiographs and CBCT images were obtained for several dental causes which were examined by the consensus of four dentomaxillofacial radiologists. The posterior maxillary segments in proximity of maxillary sinus were classified as edentulous and dentate maxillary segments. The location of maxillary sinus septa was classified as primary septa and secondary septa according to the presence of maxillary tooth at the affected site. The maxillary sinus septa were divided into three categories (anterior, middle and posterior) according to its relation with posterior maxillary teeth. Data were statistically analyzed with chi-square and Fisher's exact tests., Results: The septa were found in 23.1% and 29.8% of the maxillary sinuses on panoramic radiography and CBCT images, respectively. The majority of maxillary sinus septa were observed in dentate posterior maxillary segments on both panoramic (45.8%) radiography and CBCT (64.5%) images. Statistically significant differences (p<0.001) were found between panoramic radiography and CBCT images for presence, location and neighborhood with the posterior maxillary teeth of maxillary sinus septa., Conclusion: The results of this study demonstrated the low reliability of panoramic radiography images in the detection of maxillary sinus septa. CBCT images can provide valuable information to the clinicians about the presence and location of maxillary sinus septa., Competing Interests: Conflict of interest: None declared.

- Abstract
Objective: The main aim of the study was to investigate the effects of age in pulmonary consultation and to evaluate differences between geriatric and adult patients., Material and Methods: Consultation referrals to the clinic of chest diseases for patients from emergency, inpatient and outpatient clinics of a tertiary care general hospital between December 2010 and April 2011 were examined retrospectively. The patients were divided into two groups, namely those aged 65 years and over (geriatric patients) and those under the age of 65 years (adults)., Results: Out of 272 patients 135 (49.6%) were geriatric patients and 137 (50.4%) were adult patients. The mean age of the geriatric patients and adults was 75.6±7.1 years and 49.7±11.8 years, respectively. While the geriatric patients showed a significantly higher presence of pathologies in chest radiography, respiratory complaints and concomitant diseases compared to the adult group, the respiratory function test results were lower. The complaint of shortness of breath was higher in the geriatric group compared to the adult group (71% in geriatric patients and 59.1% in adults). The most common diagnosis was chronic obstructive pulmonary disease (COPD, 37%) in the geriatric patients and asthma (27.7%) in the adult patients. As to the results of consultations, treatment-oriented recommendations were given for 63 (46.6%) geriatric patients and approval for operation was given for 75 (54.7%) adult patients., Conclusion: Consultants should take the age of patients into consideration during evaluation in order to achieve the most appropriate treatment plan for these patients and reduce the potential postoperative complications to a minimum.

- Abstract
Background and Objective: to compare the therapeutic effects of ketamine alone or ketamine plus propofol on analgesia, sedation, recovery time, side effects in premedicated children with midazolam-ketamine-atropin who are prepared circumcision operation., Methods: 60 American Society of Anaesthesiologists physical status I-II children, aged between 3 and 9 years, undergoing circumcision operations under sedation were recruited according to a randomize and double-blind institutional review board-approved protocol. Patients were randomized into two groups via sealed envelope assignment. Both groups were administered a mixture of midazolam 0.05mg/kg+ketamine 3mg/kg+atropine 0.02mg/kg intramuscularly in the presence of parents in the pre-operative holding area. Patients were induced with propofol-ketamine in Group I or ketamine alone in Group II., Results: in the between-group comparisons, age, weight, initial systolic blood pressure, a difference in terms of the initial pulse rate was observed (p>0.050). Initial diastolic blood pressure and subsequent serial measurements of 5, 10, 15, 20thmin, systolic blood pressure, diastolic blood pressure and pulse rate in ketamine group were significantly higher (p<0.050)., Conclusion: propofol-ketamine (Ketofol) provided better sedation quality and hemodynamy than ketamine alone in pediatric circumcision operations. We did not observe significant complications during sedation in these two groups. Therefore, ketofol appears to be an effective and safe sedation method for circumcision operation., (Copyright © 2014 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

- Abstract
Background: The aim of this study was to determine phenolic acid composition and anti-parasitic effects of Peucedanum caucasicum, P. palimbioides, P. longibracteolatum and P. chryseum on Entamoeba histolytica., Methods: Methanol extracts of the plant species were prepared by soxhlet extraction. Phenolic acid compositions were determined by HPLC. Anti-proliferative effect of extracts on trophozoites was determined by using trypan blue dye exclusion test. For counting the cells, approximately a hundred of E. histolytica trophozoites were examined in each time. The data were presented as mean values with standard deviations and analyzed by repeated measures of ANOVA followed by Tukey test for post-hoc pairwise comparisons. The P-value was set at 0.05 for significance level., Results: All of the extracts showed a time and dose dependent amoebicidal action on trophozoites. Among the extracts tested, P. longibracteolatum showed the strongest amoebicidal effect on the trophozoites. As expected, this plant species also exhibited time and dose dependent activity on the trophozoites. At 4.0 mg/ml extract concentration, all of the trophozoites were killed by the extract in 72(nd) hour. Gallic (11.144 mg/g), P-hydroxybenzoic (17.646 mg/g), and o-coumaric acids (14.442 mg/g) were determined as the major phenolic acids of P. longibracteolatum. Gallic and P-hydroxybenzoic acids found in P. longibracteolatum could not be determined in other extracts. Therefore, high activity potential of this plant could probably be attributed to the presence of these phytochemicals., Conclusion: P. longibracteolatum can be further evaluated as potential therapeutic drugs for the treatment of Entamoeba infections.

- Abstract
Osteomas are benign tumors which are composed of mature compact or cancellous bone. They can be either peripheral, central or extraskeletal. The peripheral osteoma arises from surface of the bone (periosteal) whereas the central osteoma arises from the bone medullary (endosteal) and the extra-skeletal soft tissue osteoma usually develops within the muscle. Osteomas are most commonly found in the skull and facial bones. Multiple osteomas may be associated with Gardner's Syndrome. These lesions are usually painless and recurrence is uncommon after local excision. In this case report clinical, radiographic findings and treatment of a 24-year-old male patient with peripheral osteoma in the anterior mandible are presented., Competing Interests: Conflict of interest: None declared.

- Abstract
Purpose: The effects of different body positions on the middle ear were reported in several studies, but there are no data about the effects on patients under general anesthesia. The aim of this study is to determine the effect of prone position on middle ear pressure (MEP) during general anesthesia without using nitrous oxide., Methods: Twenty patients under general anesthesia during prone position were included in the study. The performed anesthesia method was the same for all patients. Remifentanil was used for analgesia instead of nitrous oxide. MEPs were measured 5 times with a middle ear analyzer: before induction (BI), after intubation (AI), after turned to the prone position (PP1), at the end of the prone position (PP2), and after returned to the supine position (SP). Duration of prone position was also recorded., Results: Of the 20 patients were 11 women and 9 men with a 49 ± 13 mean age. BI-AI, AI-PP1, PP1-PP2, and PP2-SP comparisons of both MEPs were statistically significant (P < 0.0001). Right mean MEPs were BI, -1 ± 23 daPa; AI, 41 ± 51 daPa; PP1, 124 ± 76 daPa; PP2, 152 ± 59 daPa; and SP, 63 ± 29 daPa; whereas left mean MEPs were BI, -24 ± 55 daPa; AI, 28 ± 34 daPa; PP1, 132 ± 67 daPa; PP2, 162 ± 48 daPa; and SP, 70 ± 89 daPa. Significant increases were detected at the start and continuation of the prone position. The mean duration of prone position was 98 ± 51 per minute., Conclusions: The significant MEP increases during the prone position under general anesthesia depend on a number of reasons. Among them are inhaler agents, pressure changes in mucosal blood vessels due to venous congestion, and the mastoid bone volume. Further researches are required to determine and explain the mechanisms of increase in MEP during prone position.

- Abstract
Aims: The procedure of laryngoscopic orotracheal intubation (LOTI) has many impacts on several parts of the body. But its effect on middle ear pressure (MEP) is not known well. The purpose of this study is to evaluate the MEP changes subsequent to insertion of endotracheal tube with laryngoscope., Subjects and Methods: 44 patients were included in this study with a normal physical examination of ear, nose and throat. A standard general anaesthesia induction without any inhaler agent was performed to the all patients. The MEP measurements for both ears were applied under 1 minute; before induction (BI) and after intubation (AI) with a middle ear analyzer. Also hemodynamic parameters were recorded before induction and after intubation., Results: Of the 44 patients were 25 women and 19 men with a 43.5±15.1 mean age. A statistically significant rise in MEP was seen in all patients subsequent to insertion of endotracheal tube (P<0.05). Mean right MEPs were BI: -9.5 and AI: 18.5 daPa. Also mean left MEPs were BI: -21.7 and AI: 29.1 daPa. The amount of increases in left and right MEPs were 50 daPa and 27 daPa, respectively. 20% increase in systolic blood pressure and 19% increase in diastolic blood pressure were determined after intubation. The mean heart rate was 76/min before intubation, whereas it was 102/min after intubation with a 34% increase., Conclusion: In this study bilateral significant increases in MEP were determined subsequent to LOTI. Possible factors affecting MEP may be auditory tube, size and type of the blades, drugs and face masking time. But on the other hand in our opinion cardiovascular and haemodynamic response to LOTI has the most impact over the middle ear mucosa with mucosal venous congestion.

Background and Objectives: Evaluating the incidence of nosocomial and invasive device-related infections enables the comparison of the health care associated infection (HAI) between the intensive care units of different hospitals and different units in the same hospital., Material and Methods: A retrospective surveillance study was performed to identify nosocomial infections, device-related infections rates, and causal agents from January 2007 through December 2010 in the Anesthesiology Intensive care unit (ICU). HAI were defined according to the CDC (Centers for Disease Control and Prevention) criteria, and invasive device-related infections were defined according to National Nosocomial Infection Surveillance System (NNIS) criteria., Results: During a two-year period, 939 patients were analyzed throughout a total of 7,892 patient-days. The rates of HAI were 53% in 2007, 29.15% in 2008, 28.85% in 2009 while 16.62% in 2010. Most common HAI was blood stream infection. The rate of soft tissue and skin infection was the second most common. Overall, the most common agents were Gram(-) 56.68%, Gram(+) 31.02% and Candida spp 12.3% among patients with nosocomial infections., Conclusions: The incidence of HAI in the ICU of our hospital was high, compared to the Turkish overall rates obtained at the Refik Saydam Center in 2007. When the rates of device-related infections between 2007 and 2008 were compared, they were higher in 2007. The rates of device-related infections were diminished in 2008 to below-national mean rates by infection control measures. Since the rate of urinary catheter-related infections are still high, we should exert continuous efforts for infection control., (Copyright © 2013 Elsevier Editora Ltda. All rights reserved.)

- Abstract
Tricyclic antidepressant overdose is one of the most common cause of serious drug poisonings. Sometimes amitriptyline intoxication can be difficult to treat with standard treatments. At that case hemodiafiltration (HD) can be an eligible choice. We report a successful treatment of severe case using hemodiafiltration in addition to the supportive measures. Management with gastric lavage, activated charcoal, alkalinization and supportive care is the common approach and not enough for patients in deep coma. We satisfied that HD may have a beneficial role in lethal doses of amitriptyline as an additional therapy.

- Abstract
Amoebic keratitis is difficult to treat without total efficacy in some patients because of cysts, which are less susceptible than trophozoites to the usual treatments. The aim of this study is to evaluate the in vitro amoebicidal activity of the methanolic extracts of Teucrium polium and Teucrium chamaedrys. In the presence of methanolic extracts (ranging from 1.0 to 32.0 mg/ml), numbers of the viable Acanthamoeba castellani trophozoites and cysts were decreased during the experimental process. Both extracts showed time- and dose-dependent amoebicidal action on the trophozoites and cysts. Among the extracts tested, T. chamaedrys showed the strongest amoebicidal effect on the trophozoites. In the presence of 16 mg/ml or above extract concentrations, no viable trophozoites were observed within 48 h. In the case of T. polium, no viable trophozoites were observed within 48 h at 32 mg/ml concentration. As expected, cysts were found more resistant to the extracts than the trophozoites.

- Abstract
In some patients, complete treatment of amoebic keratitis is difficult because of the resistance of cysts to therapeutic agents. The aim of this study was to evaluate the in vitro amoebicidal activity of methanolic extracts of Origanum syriacum and Origanum laevigatum. In the presence of methanolic extracts (ranging from 1.0 to 32.0mg/ml), numbers of the viable Acanthamoeba castellanii trophozoites and cysts were decreased. Both extracts showed a time and dose dependent amoebicidal action on the trophozoites and cysts. Of the extracts tested, O. syriacum showed the stronger amoebicidal effect on the trophozoites and cysts. In the presence of 32 mg/ml extract, no viable trophozoites were observed within third hour. The extract was also found effective against the cysts within 24th hour. In the case of O. laevigatum, no viable trophozoites were observed within 72nd hour at the concentrations of 16 and 32 mg/ml. As expected, cysts were found more resistant to the extracts than the trophozoites., (Copyright © 2012 Elsevier Inc. All rights reserved.)

- Abstract
Congenital laryngeal cysts (CLCs) are rare and may be fatal. Although CLCs have the potential to cause severe airway obstruction and death, these are not common presentations at birth. The most common CLCs are the aryepiglottic cysts, with the epiglottic cysts being the least common. In this report, a newborn with severe airway obstruction at birth, caused by a giant congenital epiglottic cyst, is presented.

- Abstract
The aim of this study is to evaluate the in vitro amoebicidal activity of the aqueous extracts of Pastinaca armenea and Inula oculus-christi from Turkey. In the presence of aqueous extracts (ranging from 1.0 to 32.0 mg/ml), numbers of the viable Acanthamoeba castellanii trophozoites and cysts were decreased during the experimental process. Both extracts showed a time- and dose-dependent amoebicidal action on the trophozoites and cysts. Among the extracts tested, I. oculus showed the strongest amoebicidal effect on the trophozoites and cysts. In the presence of 32.00 mg/ml extract solution in the media, no viable trophozoites were determined from the time of 24 h. Moreover, in the presence of 16.00 mg/ml I. oculus-christi extract, no viable trophozoites were detected in 72 h of the experiment. Effectiveness of I. oculus-christi extract was found moderate against the cysts. In the presence of 32.00 mg/ml extract, only 25.3% of the total cysts were killed effectively. In the case of P. armenea, 40.3% and 23.0% of the trophozoites and cysts were killed in the presence of 32.00 mg/ml extract at the end of the experimental process (72 h), respectively.

- Abstract
Background/purpose: Two Demodex species are known to live on people. Demodex folliculorum lives in the openings of hair follicles alone or in groups. D brevis lives in the depths of the sebaceous glands alone. There are different related on the epidemiology of Demodex species have been published., Method: In this study, taking into account that the parasite is transmitted through close contact from person to person, we aimed to evaluate the relation between the presence of Demodex spp with gender and age among the Health hazard bearing and sanitary establishment operators and workers who came for porter examination., Results: For this purpose, 862 male and 215 female patients with a total of 1077 volunteers from the face area of the standard superficial skin biopsy (SSSB) method and studied samples were taken. More than five mites in 1 cm(2) density was defined as positive. In investigated samples 37.3% Demodex spp. positivity was detected. Only two were found to be D brevis and the others were D folliculorum. The study revealed statistically significant relationships between the positivity of parasites with the occupational group, age and sex., Conclusion: Since the prevalence of Demodex among healthy individuals without any complaint was found to be 37%, we believe Demodex spp should be investigated in porter examinations of people who have dermatological complaints., (Copyright © 2012.

- Abstract
Amoebic keratitis is difficult to treat without total efficacy in some patients because of cysts, which is less susceptible than trophozoites to the usual treatments. The aim of this study is to evaluate the in vitro amoebicidal activity of the methanolic extracts of Peucedanum caucasicum, Peucedanum palimbioides, Peucedanum chryseum, and Peucedanum longibracteolatum, which are endemic in Turkish flora except P. caucasicum. Extracts were evaluated for their amoebicidal activities using an inverted light microscope. In the presence of methanolic extracts (ranging from 1.0 to 32.0 mg/ml), numbers of the viable Acanthamoeba castellani trophozoites and cysts were determined during the experimental process (72nd hour). All of the extracts showed a time and dose-dependent amoebicidal action on the trophozoites and cysts. Among the extracts tested, P. longibracteolatum showed the strongest amoebicidal effect on the trophozoites and cysts. In the case of 32 mg/ml concentration of extract, no viable trophozoites or cysts were determined between 24th and 72nd hour. Similar results were obtained from the extract at 16.0 mg/ml concentration against trophozoites. At this concentration value, number of viable cysts was determined as 10.6 ± 2.1 in the 24th hour. In the presence of 8.0 mg/ml extract solution, no viable trophozoites were determined in the 48th hour. At the same concentration, 51% of the cysts were killed by the extract in the 72nd hour. As expected, cysts were found more resistant to the extracts than the trophozoites.

- Abstract
The aim of this study was to determine middle ear pressure changes during the operation performed under anaesthesia induced by isoflurane or desflurane. This was a prospective, case-control study. A total of 38 children with no middle ear pathology scheduled for inguinal hernia surgery were included in the study. Group I (n = 22) received isoflurane and Group II (n = 16) received desflurane. Baseline tympanometry was performed before the anaesthesia on both ears, and tympanometry was repeated 5, 10 and 15 minutes after the administration and 10 and 30 minutes after the withdrawal of anaesthetic agents. Data were analyzed using the Mann-Whitney U (inter-group) and the Wilcoxon test (intra-group) procedures. The mean middle ear pressure values in the 44 ears of the 22 children in Group I and the 32 ears of the 16 children in Group II did not show any significant difference before the anaesthesia by either anaesthetic agent (p > 0.05). Increase in the mean middle ear pressure values at the 5(th) and 10(th) minute of the operation was significant different between both groups (2.84 and 5.80 daPa for isoflurane; 59.06 and 72.81 daPa for desflurane; p ≤ 0.05). Desflurane is more increased than isoflurane on intra-tympanic pressure and isoflurane may be used more safely than desflurane in middle ear operations. The low effect of isoflurane on intra-tympanic pressure can be explained by the high blood/gas partition coefficient compared to desflurane.

- Abstract
The study was carried out to determine the prevalence of parasites in three socioeconomically-different regions (Alibaba, Esentepe, and Cayboyu) of Sivas, Turkey, to determine the most accurate method for the diagnosis of taeniasis and enterobiasis, to determine the importance of household visits in primary healthcare to control parasitic diseases, and to treat intestinal parasitic diseases in those regions. Both stool specimens and cellophane tape (CT) samples were taken from 1,864 participants during 641 household visits in the three regions. The age groups included were pre-school [(0-6 year(s)], primary school (7-15 years), and the upper age group (16 years and above). The total prevalence of intestinal parasites in the three regions was 37.2%. Eleven intestinal parasite species were detected in both stool specimens and CT samples. Giardia intestinalis and Enterobius vermicularis were the most frequent species identified in all the three regions. Region I (Alibaba) had a higher prevalence of parasites compared to the other two regions. There was no significant difference between Region II (Esentepe) and Region III (Cayboyu) in isolation of intestinal parasites. There were statistically significant differences between the age groups when the rates of parasitic infection were compared. The highest prevalence of parasitosis was observed among the age group of 7-15 years and in the socioeconomically lowest one of the three regions. While the most accurate way of diagnosis for taeniasis was the combined usage of the CT and direct preparation methods, the CT method was the best method for the diagnosis of enterobiasis. Thus, the local administrators in cities need to pay more attention to the prevention of parasitic infections along with improvements in educational, environmental and sanitary conditions.
