Appendectomy in the surgical treatment of benign ovarian mucinous cystadenomas — is it necessary?

Objectives: To determine if appendectomy as an adjunctive procedure is necessary in the surgical treatment of benign ovarian mucinous cystadenomas. Material and methods: Retrospective analysis of clinical data: in a research hospital, obstetrics and gynecology depart­ment setting, 63 cases of benign ovarian mucinous cystadenomas confirmed in the pathological evaluation were revised. 59 had the complete clinical, final pathological and follow-up data available and were included. Results: 20.6% (13/59) went through an appendectomy. Basic characteristics of patients with different appendiceal pathologies did not show any significant differences. In the study group the mean age, parity, adnexial mass size were (40.1 ± 12.4); (1.3 ± 1.1) and (9.1 ± 5.3 cm), respectively. Patients were either operated laparoscopically (20), laparotomically (39) to perform a unilateral salpingoopherectomy/cystectomy. In 7 patients, oopherectomy was an additional procedure with: 2 abdominal hysterectomies, 4 cesarean sections and 1 total laparoscopic hysterectomy. 2 synchronous appendiceal pathologies (mucinous cystadenomas of the appendix) were defined in appendectomies performed. In these cases, the ovarian tumour sizes were: 7 cm and 4 cm. Conclusions: In the presence of a benign or borderline unilateral ovarian mucinous tumour as defined during the operation and especially if it is larger than 10–12 cm and with normal peritoneal and appendiceal gross morphology, appendectomy is not a necessary adjunctive procedure

Nocebo Hyperalgesia in Patients With Fibromyalgia and Healthy Controls:An Experimental Investigation of Conditioning and Extinction Processes at Baseline and 1-Month Follow-up

Nocebo effects are adverse treatment outcomes that are not ascribed to active treatment components. Potentially, their magnitude might be higher in patients with chronic pain compared to healthy controls since patients likely experience treatment failure more frequently. The current study investigated group differences in the induction and extinction of nocebo effects on pressure pain at baseline (N = 69) and 1-month follow-up (N = 56) in female patients with fibromyalgia and matched healthy controls. Nocebo effects were first experimentally induced via classical conditioning combined with instructions on the pain-increasing function of a sham transcutaneous electrical nerve stimulation device, then decreased via extinction. One month later, the same procedures were repeated to explore their stability. Results suggest that nocebo effects were induced in the healthy control group during baseline and follow-up. In the patient group, nocebo effects were only induced during follow-up, without clear group differences. Extinction was only observed during baseline in the healthy control group. Further comparisons of nocebo effects and extinction indicated no significant changes across sessions, possibly suggesting their overall magnitudes were stable over time and across groups. In conclusion, contrary to our expectations, patients with fibromyalgia did not have stronger nocebo hyperalgesia; instead, they might be less responsive to nocebo manipulations than healthy controls. Perspective: The current study is the first to investigate group differences in experimentally manipulated nocebo hyperalgesia between chronic pain and healthy populations at baseline and 1-month follow-up. Since nocebo effects are common in clinical settings, their investigation in different populations is essential to explain and minimize their adverse effects during treatment.</p

Bioecological characteristics of Planococcus citri Risso, 1813 (Hemiptera: Pseudococcidae) under constant and alternating temperatures1

Planococcus citri Risso, 1813 (Hemiptera: Pseudococcidae), is one of the major pest of citrus and many other orchards crops, and ornamental plants in subtropical and tropical regions of the world. The influence of temperature on P. citri development and fecundity has a critical role in integrated pest management strategies to reduce the population to below the economic threshold by biological or chemical control methods. The study investigated some bioecological characteristics, such as, development time, duration of biological stages, sex ratio, daily and total fecundity per female, and longevity of P. citri, under different temperature regimes during 2015-2016 in Citrus Pest Laboratory at Çukurova University. The shortest egg stage development for females and males were determined as 2.7 and 2.7 d with alternating temperatures of 25/30°C (12:12 h), respectively. The first nymph stage lasted 7.86 d for females, and 8.1 d for males at 25°C. The longest duration for the second nymph stage was obtained at 15°C with 25.7 and 22.5 d for females and males, respectively. The third nymph stage for P. citri females completed in 7.0 d at 25°C, and the pupal stage for P. citri males lasted 7.8 d at 25°C. The development thresholds of females and males were calculated as 8.5 and 9.5°C, respectively. Also, thermal constants of females and males were 666.67 and 500.00 degree-days. The optimum development temperature was determined as 25/30°C

Side effect of some insecticide used in citrus orchard on aphid parasitoid, Lysiphlebus confusus Tremlay and Eady, Lysiphlebus fabarum (Marshall), and lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae) [Turunçgil bahçelerinde kullanilan bazi ilaçlarin yaprakbiti parazitoitlerinden Lysiphlebus confusus Tremlay & Eady, Lysiphlebus fabarum (Marshall) ve Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae)'e karş'i etkileri]

The side effects of the most common used insecticides in citrus orchards such as spirotetramat, pyriproxyfen, spinosad, chlorpyrifos-ethyl 480, paraffinic mineral oil and mineral oil on pupa and adult stages of Lysiphlebus confusus Tremlay and Eady, L. fabarum (Marshall) and L. testaceipes (Cresson) were evaluated under guidelines of IOBC/WPRS. Contact toxicity on adult parasitoids and dipping method for pupal stage of parasitoids were used to evaluate potential adverse effects of insecticides on the survival and the reproductive capacity of the parasitoid. According to result of these study, chlorpyrifos-ethyl 480, paraffinic mineral oil and mineral oil are harmful and moderately harmful on pupa and adult stages of all three species according to IOBS classification. Spinosad is harmless on pupa stages, harmful and moderately harmful on adult stages of three species. Effect of spirotetramat and pyriproxyfen are lesser than other insecticides and harmless on pupa, harmless and slightly harmless on adult of three species. While the parasitoids exposed to Chlorpyrifos-ethyl 480, paraffinic mineral oil and mineral oil at pupa stages didn't laid eggs, the parasitoids exposed to spirotetramat, pyriproxyfen, spinosad laid eggs as control groups.. Adult parasitoids subjected to spirotetramat and pyriproxyfen laid eggs as control groups

Impacts of festivals and events on residents’ well-being

This study investigated how residents’ participation in local festivals may influence their subjective-well-being and their quality of life. Using data collected from local attendees of a film festival, this study examined the relationship between socio-cultural impacts of a festival and subjective well-being of local residents. Findings revealed that while community benefits and cultural/educational benefits are positive predictors of subjective well-being of residents, quality life concerns were found to have negative impact on the well-being of residents. Findings also revealed no significant relationship between community resource concerns and subjective well-being of residents

The determination of total protein, total soluble carbohydrate and pigment contents of some macroalgae collected from Gemlik-Karacaali (Bursa) and Erdek-Ormanli (Balikesir) in the Sea of Marmara, Turkey

In this study, 12 taxa from the Chlorophyta, Phaeophyta and Rhodophyta were collected from different depths at Gemlik-Karacaali and Erdek-Ormanlı. A total of 175 specimens from these divisions were used to determine Total Protein (TP), Total Soluble Carbohydrate (TSCH) and Chlorophyll a (Chl a), Chlorophyll b (Chl b), Chlorophyll c (Chl c), total carotenoid (Car) contents and Chl b/Chl a, Chl c/Chl a, Car/Chl a, Car/Chl b, Car/Chl c ratios. TP, TSCH and pigment contents varied significantly with respect to the algal taxa, stations and depth distribution. In addition, individual differences were important in all of the measured parameters. The maximum TP contents (0.94%–31.03%) were determined in some of the Rhodophyta. In some green seaweeds belonging to the genus Ulva L., the TP content was determined between 2.9%–28.1%. Lower TP contents were determined in Cystoseira barbata (Good) C. Agardh (1.1%–4.3%). In contrast to TP contents, TSCH values were very low; maximum TSCH were determined in Ulva species, as were protein contents. In conclusion, the variations in TP, TSCH and pigment in 12 taxa of macroalgae were analysed according to station, depth, and environment
