Evaluation of cornea and anterior chamber results of patients with obstructive sleep apnea syndrome

Objective: To evaluate the anterior segment findings measured via corneal topography of patients with obstructive sleep apnea syndrome (OSAS) and to compare the findings with normal subjects.Methods: A total of 43 eyes from 43 patients with OSAS and 43 eyes from 43 healthy persons who were referred to eye clinics from 2012 to 2016 were randomly selected and included in this retrospective study. Routine eye examination and anterior segment findings measured via corneal topography were recorded for both groups. Central corneal thickness (CCT), keratometry values (K1, K2, and Kmax), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA) of the two groups were compared.Results: The mean CCT values of the control and OSAS groups were 567.23 +/- 31.17 and 544.4 +/- 36.44 (p=0.002), respectively. The mean CV (HR) was found to be 60.51 +/- 8.44 in the control group and 59.78 +/- 3.47 in the OSAS group (p=0.04). There was no statistically significant difference between the OSAS and control groups in terms of mean age, K1, K2, Kmax, ACV, ACD, and ACA (p>0.05). The mean apnea/hypopnea index (AHI) score of the OSAS group was found to be 21.82 +/- 12.79. There was no negative or positive correlation between the AHI score and age, CCT, K1, K2, Km, SCL, SCL, SCA, and CV.Conclusion: Central corneal thickness and CV are lower in OSAS patients than in normal people

Mapping the establishment and invasiveness potential of rainbow trout (Oncorhynchus mykiss) in Turkey: With special emphasis on the conservation of native salmonids

Rainbow trout (Oncorhynchus mykiss) has become by far the most frequently farmed freshwater fish species in Turkey, whereas very little is known about its establishment and invasiveness potential. We explored this potential through a combination of Maxent habitat suitability model and the Aquatic Species Invasiveness Screening Kit (AS-ISK) on the river basin scale by generating an overall risk score (ORS). The outcome of this approach was also incorporated with the spatial analysis of native salmonid species by generating a relative vulnerability score (RVS) to prioritize susceptibility of native species (or populations) and to propose risk hotspots by identifying their potential geographic overlap and interaction with O. mykiss. Results suggest that the northern basins (Eastern Black Sea, Western Black Sea and Marmara basins) are the most suitable basins for O. mykiss. According to the Basic Risk Assessment (BRA) threshold scores, O. mykiss is classified as "high risk" for 3 (12.0%) of the 25 river basins screened (Western Black Sea, Eastern Black Sea and Maritza-Ergene), and as "medium risk" for the remaining basins. The climate change assessment (CCA) scores negatively contributed the overall invasiveness potential of O. mykiss in 22 (88.0%) of the river basins and resulted in zero contribution for the remaining three, namely Aras-Kura, coruh river and Eastern Black Sea. The ORS score of river basins was lowest for Orontes and highest for Western Black Sea, whereas it was lowest for Konya-closed basin and highest for Eastern Black Sea, when CCA was associated. The micro-basins occupied by Salmo rizeensis had the highest mean habitat suitability with O. mykiss. Among the all species, S. abanticus had the highest RVS, followed by S. munzuricus and S. euphrataeus. The overall outcome of the present study also suggests that the establishment and invasiveness potential of O. mykiss may decrease under future (climate warmer) in Turkey, except for the northeast region. This study can provide environmental managers and policy makers an insight into using multiple tools for decision-making. The proposed RVS can also be considered as a complementary tool to improve IUCN red list assessment protocols of species

Ligula intestinalis infection in a native Leuciscid hybrid (Alburnus derjugini x Squalius orientalis) in the Kurtun Dam Lake, Northeast Anatolia

Taxonomic evaluations are needed to accurately determine the host selection of fish parasites. The present study is a multidisciplinary research in the field of basic and fish diseases sciences. The description of the hybrid species of Squalius orientalis and Alburnus derjugini and infection of Ligula intestinalis in these hybrid fish were reported for the first time from the Kurtun Dam Lake in northeast Turkey. A total of 450 fish were sampled in March, August, and October in 2020 using gillnets. Detailed morphological characteristics (n = 24) were compared to determine the difference among ancestors and hybrid species. The prevalence of L. intestinalis between the sampling periods and the size groups of fish (0 - 10, 11 - 15, and >= 16 cm in length) were examined. Moreover, the highest prevalence of the parasite was observed in October (78.94 %), with a size range of 0 - 10 cm in length (77.8 %). In addition, the total prevalence of the parasite was 48.44 %. The results revealed that most of the diagnostic metric and meristic features of hybrid fish were ranging between the data of S. orientalis and A. derjugini. According to previous reports, when hybrid individuals were compared with their ancestors in terms of prevalence, hybrid individuals were more susceptible to L. intestinalis infections. This study was unique as it provided the first record of L. intestinalis in a hybrid fish population.Scientific Research Project Coordination Unit of Recep Tayyip Erdogan University FDK-2020-108

One-stage operation for hydatid disease of lung and liver: Principles of treatment

AbstractObjective: Hydatid disease is endemic in many countries throughout the world. Although we do not have exact figures, the disease is prevalent in Turkey. A considerable number of patients have additional liver cysts as well. In this study we reviewed our experience with hydatid disease of the lung and liver and discussed the principles of treatment. Methods: From 1971 to 1999, 2509 patients with pulmonary hydatidosis were referred to us, and 485 of them had concomitant liver cysts. Of these, 405 patients had cysts located on the dome of the liver, and they were operated on with phrenotomy through a right thoracotomy. Eighty patients who were found to have concomitant liver cysts in the lower part of the liver were referred to general surgery for a laparotomy. Results: Hydatid cysts located in the lungs were managed by means of cystotomy and capitonnage. For liver cysts, cystotomy and inversion of the cavity with sutures was the surgical method of choice, and a drain was left in place. In case of multiple cysts in the liver, needle aspiration was preferred. Twelve major complications, including excessive biliary drainage and bronchobiliary fistula, occurred in these patients. Conclusions: We believe that management of pulmonary and hepatic cysts simultaneously through the thoracic route is convenient and should be encouraged in patients because this prevents a second operation. Needle aspiration can be applied only for liver cysts. It is absolutely contraindicated in lung hydatid cysts.J Thorac Cardiovasc Surg 2002;124:1212-

Dodin fungusitinin Vicia faba L. bitkisinde total protein miktarı ve peroksidaz aktivitesi üzerine etkisi

Bu araştırmada dodin fungusitinin Vicia faba L. fizyolojisi üzerindeki etkisi, total protein miktarı ve peroksidaz (POX) aktivitesi aracılığıyla değerlendirilmiştir. Bu doğrultuda, dört haftalık V. faba fideleri 0.04 mL/L, 0.08 mL/L ve 0.16 mL/L'lik dodin konsantrasyonları ile muamele edilmiştir. Bu işlemlerden sonra bitki örneklerinin yaprakları 24, 48 ve 72 saat ara ile hasat edilmiştir. Yapılan analizler sonucunda, artan dodin konsantrasyonu ve muamele süresiyle total protein miktarı kontrole göre önemli ölçüde azalırken, peroksidaz aktivitesi yükselmiştir. Elde edilen sonuçlar dodinin bitki savunma sistemini uyardığını göstermiştir.This research was to evaluate the effects of dodine on the physiology of Vicia faba L. through total protein content and peroxidase (POX) activity. According to this, four weeks old seedlings were treated with 0.04 mL/L, 0.08 mL/L and 0.16 mL/L concentrations of dodine. Then, the leaves of plant samples were harvested with 24, 48 and 72 hours intervals. Our results have showed that while the total protein content were decreased significantly, POX activity was increased with the increased concentration of dodine and exposure time when compared with control seedlings. This research have shown that dodine can stimulate the plant defense system

Wyniki leczenia uszkodzenia nerwu strzałkowego na wysokości kolana: doświadczenie oddziału szpitala wo¡skowego

Background and purpose We investigated the management outcome of common peroneal nerve decompression at the knee level between the years 2005 and 2009. Material and methods Thirty consecutive patients with knee-level peroneal nerve injury who underwent decompression surgery and external neurolysis at our institution were evaluated preoperatively and postoperatively by electrophysiological studies and motor examination (Medical Research Council grading). Results Twenty-eight of the cases were male and 2 were female. Mean age was 31.1 for males and 57.5 for females. Physical activity during military training (overstretch/contusion) was the cause of nerve lesion in the majority of the patients (n = 28, 93%). Mean time interval between the diagnosis and the surgery was 5 months. Follow-up time ranged from 3 to 48 months (mean: 14 months). Twenty-nine of 30 (97%) patients recovered totally or near totally in foot/toe dorsiflexion. Conclusions Early decompression and neurolysis of the common peroneal nerve (CPN) at knee level after strenuous physical activity offers excellent functional recovery. Additionally, for knee-level CPN injuries, in order to minimize the postoperative scar, pain and delay in wound healing, we strictly advocate short ‘lazy S-shaped incision’ around the fibular head in supine position unlike the classical extensive opening up to the superior border of the popliteal fossa in prone position.Wstęp i cel pracy Autorzy ocenili wyniki chirurgicznego odbarczenia nerwu strzałkowego wspólnego na wysokości kolana, wykonywanego w latach 2005–2009. Materiał i metody Przedoperacyjnej i pooperacyjnej ocenie klinicznej (w skali Medical Research Council) oraz elektrofizjologicznej poddano 30 kolejnych pacjentów z uszkodzeniem nerwu strzałkowego na wysokości kolana, u których wykonano odbarczenie chirurgiczne z zewnętrzną neurolizą. Wyniki Wśród leczonych było 28 mężczyzn (średnia wieku: 31,1 roku) i dwie kobiety (średnia wieku: 57,5 roku). U zdecydowanej większości pacjentów (n = 28, 93%) przyczyną uszkodzenia nerwu była aktywność fizyczna w czasie szkolenia wojskowego (nadmierne rozciągnięcie/stłuczenie). Średnia czasu od rozpoznania do operacji wyniosła 5 miesięcy. Obserwacja po zabiegu trwała od 3 do 48 miesięcy (średnia: 14 miesięcy). U 29 na 30 chorych (97%) uzyskano pełny lub prawie pełny powrót zgięcia grzbietowego stopy/palców. Wnioski Wczesne chirurgiczne odbarczenie i neuroliza nerwu strzałkowego wspólnego na wysokości kolana w leczeniu urazu powstałego wskutek nadmiernej aktywności fizycznej daje możliwość znakomitej poprawy czynnościowej. Ponadto w przypadku uszkodzeń nerwu strzałkowego wspólnego na wysokości kolana w celu zminimalizowania blizny pooperacyjnej, nasilenia bólu i opóźnienia w gojeniu się rany pooperacyjnej autorzy usilnie zalecają krótkie cięcie w kształcie wydłużonej litery „S” wokół głowy strzałki u chorego w pozycji leżącej na plecach zamiast klasycznego otwarcia aż do górnej granicy dołu podkolanowego w pozycji leżącej na brzuchu

Diversity, phylogeny and intraspecific variability of Paradiplozoon species (Monogenea: Diplozoidae) parasitizing endemic cyprinoids in the Middle East

Diplozoidae are common monogenean ectoparasites of cyprinoid fish, with the genus Paradiplozoon being the most diversified. Despite recent studies on Diplozoidae from Europe, Africa and Asia, the diversity, distribution and phylogeny of this parasite group appears to be still underestimated in the Middle East. The objective of this study was to investigate the diversity, endemism and host specificity of diplozoids parasitizing cyprinoid fish from the Middle East, considering this region as an important historical interchange of fish fauna, and to elucidate the phylogenetic position of Middle Eastern Paradiplozoon species within Diplozoidae. Four Paradiplozoon species were collected from 48 out of 94 investigated cyprinoid species. Three known species, Paradiplozoon homoion, Paradiplozoon bliccae and Paradiplozoon bingolensis, were recorded on new cyprinoid host species, and a new species, Paradiplozoon koubkovae n. sp., was recorded on Luciobarbus capito and Capoeta capoeta from the Caspian Sea basin in Iran and Turkey. Paradiplozoon bliccae, exhibiting a wide host range in the Middle East, expressed both morphological and genetic intraspecific variabilities. The four Paradiplozoon species collected in the Middle East were placed in divergent clades, showing the rich evolutionary history of diplozoid parasites in the Middle East. Our study also revealed that two lineages of African diplozoids have a Middle Eastern origin. We stress the importance of applying an integrative approach combining morphological, ecological and molecular methods to reveal the real diversity of diplozoids
