Ovarian cystectomy in endometriomas: Combined approach
No full textEndometrioma is one of the most frequent adnexal masses in the premenopausal population, but the recommended treatment is still a subject of debate. Medical therapy is inefficient and can not be recommended in the management of ovarian endometriomas. The general consensus is that ovarian endometriomas larger than 4 cm should be removed, both to reduce pain and to improve spontaneous conception rates. The removal of ovarian endometriomas can be difficult, as the capsule is often densely adherent. While the surgical treatment of choice is surgical laparoscopy, for conservative treatment, the preferred method is modified combined cystectomy. Cystectomy can be destructive for the ovary, whereas ablation may be incomplete, with a greater risk of recurrence. To the best of our knowledge, the modified combined technique seems to be more efficient in the treatment of endometriomas.3SEP177-1891
Bibliometric analysis of amebiasis research
No full textAim: Amebiasis is a disease caused by protozoon Entamoeba histolytica, that results in amoebic dysentery. While intestinal parasites are the third leading cause of death, especially in developing countries, it has been of global concern. Bibliometric methods have been used in the parasitology discipline for more than 30 years, however there is not any bibliometric study on amebiasis in the literature. Our aim was to analyse the published literature on amebiasis by bibliometric methods.
Material and methods: A systematic evaluation of the literature using the Scopus database was made from inception to 2021. The search terms ‘amebiasis’, ‘Entamoeba’, ‘Entamoeba histolytica’, and ‘amoebic dysentery’ were used. The authors, publication year, title, publishing country/journal/institution, title, keywords, and citation numbers were acquired for each article. Descriptive data analysis was conducted via Microsoft Excel 2010 and Scopus database’s graphics were used.
Results: Among 7,140 articles, 18.9 % of them were published open access, and 72.75 % of them were in the English language. Most of the articles were from the area of medicine. The USA, Mexico, and India were the top leading countries. The number of publications did not fall below 50 per year since 1950. There was an increasing number of citations on amebiasis research recently.
Conclusion: Amebiasis is a global concern as one of the leading infectious causes of mortality in developing countries. Bibliometric analysis has shown the growing attraction to the amebiasis research, so it will continue to be global public health issue.
Key words: amebiasis, bibliometric analysis, Entamoeba histolytica, bibliometric
Life Long Learning Preferences of General Surgeons After Covid-19 : Hybrid ModelGenel Cerrahların Covid-19 Sonrasında Yaşam Boyu Öğrenme Tercihleri : Hibrit Model
No full textAim: For a surgeon during his professional career; Increasing their knowledge and experience, improving their professional skills and sharing their knowledge and experience is a necessity rather than a choice. The COVID-19 pandemic has revealed new choices in the concept of lifelong learning, with virtual meetings scheduled by surgeons using videoconferencing applications over the internet. In this study, we evaluated the compliance of general surgeons to webinars during the COVID-19 outbreak and their future training expectations with a questionnaire. Design: A questionnaire of 20 questions was prepared. The questionnaire was administered questions without aiming to obtain the personal information of the participants. . This survey was announced on the social media application Twitter. Survey questions were answered by 108 participants. Results: In the survey participated by surgeons, we concluded that short-term presentations, edited surgery videos and question-answer activities will be preferred more, and webinars held in the evening will be preferred more than those planned at the weekend. During the pandemic, it was determined that surgeons preferred free webinars and attended more national and international meetings compared to the pre-pandemic period. Respondents stated that they would prefer hybrid meetings in the future. Results: Considering the results of our social media-mediated survey: there is an intense participation in online seminars by surgeons. We also concluded that in the near future, surgeons will prefer hybrid training models rather than face-to-face training to improve and update themselves.</p
Rectal Foreign Body Successfully Removed by Colonoscopic Snare Wire
No full textAim: The most common cause of rectal foreign bodies are objects used for sexual stimulation voluntarily by the patient. Different treatment methods are reported in the literature, and this article reports the transanal removal of the foreign body in the rectum with a snare wire without anesthesia, accompanied by colonoscopy. Case: An 80-year-old male patient was admitted to the emergency room because of the plastic rectal shower head that remained in the rectum and could not be removed while he was using a rectal douche for constipation. Contrast-enhanced abdominal computed tomograpyh (CT) showed a foreign body located in the rectosigmoid region without perforation findings. 12x1,5 cm tubular, well-circumscribed plastic foreign body embedded in the stool was removed with the help of colonoscopy in a controlled manner by holding it from its distal end with the help of endoscopic snare wire. Conclusion: Rectal foreign bodies can often be removed by the patient. However, in cases of foreign bodies in the rectum admitted to the hospital, the treatment method varies according to the type and location of the object, the occurrence of the event, and whether there are perforation findings in physical examination and imaging. Digital rectal examination is the critical first step in evaluating a patient with a rectal foreign body. Bedside extraction as the first-line treatment for low-lying anorectal foreign bodies without signs of perforation; endoscopic extraction is recommended as the first step in anorectal foreign bodies located high above the rectosigmoid junction. Because in cases without perforation, transanal removal of the foreign body is considered the first-line treatment and the success rate is approximately 75 %. The most essential condition for successful transanal removal of the foreign body in the rectum is the relaxation of the patient. Endoscopic examination is also recommended to evaluate the condition of the intestinal wall after the removal of the foreign body. In our case, we also removed the foreign body, which we found to be located in the middle rectum, in accordance with the literature, endoscopically.</p
Comparison of Drainage, Delayed Pits Excision, and Closure With Excision and Secondary Healing in Pilonidal Sinus Abscess Cases
No full textA pilonidal abscess is an emergency situation which requires immediate drainage and is usually seen in young men. We aimed to compare incision and draining (I&D) of acute pilonidal abscess (PSA) and healing by secondary intention with I&D and subsequent delayed pits excision and closure (PE/PC). A total of 62 patients admitted with PSA were randomized to undergo either I&D and healing by secondary intention (group 1, n = 33) or I&D and PE/PC (group 2, n = 29). Demographic characteristics of the patients, abscess depth and location, duration and healing times of the symptoms, time required to return to work, and ratio of chronic pilonidal sinus (PNS) development were recorded, and the two methods were compared. No statistically significant differences were found between the groups in relation to sex, age, and preoperative findings, including discharge, infection, pain, and length and depth of abscess. There was no difference in length of hospital stay between the groups, and no statistically significant difference was found between the groups in terms of complication rate (P = 0.298). A statistically significant difference (P = 0.033) was, however, found between the two groups in the recurrence rate of a pilonidal abscess (9.09% in group 1 versus 3.44% in group 2). A statistically significant difference was also observed between the groups in terms of development of chronic PNS (P = 0.020). According to the results of our study, I&D and PE/PC should be the primary procedure used, as opposed to skin incision, curettage, and secondary healing for the treatment of PSA
Renal transplant hastalarında idrar sodyum atılımının metabolik sendrom, hipertansiyon ve greft fonksiyonu ile ilişkisinin değerlendirilmesi
No full textAim: To evaluate the relationship between high sodium intake determined by spot urinary sodium excretion with metabolic syndrome, hypertension, and graft function in renal transplant (RT) recipients. Materials and Methods: 152 RT (35.5% were female) recipients were enrolled. The demographic characteristics, office blood pressure (BP) values, height, weight, body mass index, waist and hip measurements, immunosuppressive drugs, other medications, and biochemical parameters of the patients were recorded. Spot urinary sodium and protein excretions were measured in the RT recipients' first-morning urine. The patients were grouped as low sodium excretion (≤57 mmol/L) and high sodium excretion (≥58 mmol/L) based on the median value. Results: When the groups were compared according to spot urinary sodium excretion, no difference was found in terms of creatinine values, systolic BP and diastolic BP (p=0.21, p=0.18 and p=0.80, respectively). In the low sodium group, creatinine values were significantly lower (p<0.001), and eGFR was high in female patients (p=0.03). The mean protein in spot urine was lower in women (p=0.03). In the high sodium group, BUN and creatinine levels were significantly higher in male patients than in female patients (p=0.04 and p=0.02, respectively). The ejection fraction was significantly lower in male patients than in female patients (p=0.008). When the spot urinary sodium excretion of patients with and without metabolic syndrome was compared, no difference was found between the two groups (p=0.99). Conclusion: Spot urinary sodium excretion can an inexpensive and relatively effective screening method that can be used to evaluate sodium intake in RT patients. It can be considered a more valuable follow-up method, especially in RT recipients with male gender, kidney dysfunction, and high BP
A case with ICF syndrome lost to rubella pneumonitis
No full textThe immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is a rare autosomal recessive disorder characterized by variable immunodeficiency, instability of the pericentromeric heterochromatin, and facial dysmorphism. Here we report a new case of ICF syndrome who died of rubella pneumonitis. A six year-old-girl who was the first child of consanguineous parents was admitted to the hospital because of bronchopneumonia. Laboratory investigations revealed pan-hypogammaglobulinemia, lymphoperria, normal proportions of peripheral blood lymphocytes with an inverted CD4/CD8 ratio, and interstitial pneumonia with a positive serology of acute rubella infection. The ICF syndrome was diagnosed by centromeric instability in the standard cytogenetic analysis. An inclusion body was demonstrated in the lung biopsy after the death of the patient. Chromosomal investigation could be helpful along with other tests for diagnosis of variable immunodeficiency accompanied by facial dysmorphism
Preliminary investigation of a swirl stabilized premixed combustor
No full textExperiments were conducted in a swirl stabilized premixed combustor at atmospheric pressure in order to study the stability and structure of lean premixed methane air flames. Swirl number of the combustor was 0.74. The lab scale combustor was operated up to 30 kW of thermal power during measurements. Experiments focused on two main aspects of the combustion system. First the relation between the cold flowfield and the flame stabilization is examined. It is observed that, the structure of the flame near the dump plane corresponds closely to the features of the non-reacting air flowfield. The flame is seen to be stabilized on the boundary of the recirculation region. Lean blowout limits of the combustor that operates within the flamelet regime were also recovered. A correlation linking the blowout equivalence ratio to laminar flame speed is presented. (C) 2012 Elsevier Ltd. All rights reserved
Comparison of the Efficacy of Homologous and Autologous Platelet-Rich Plasma (PRP) for Treating Androgenic Alopecia
No full textAndrogenetic alopecia (AGA), the most common cause of hair loss in both sexes, accounts for 95% of all cases of hair loss. Although the literature has suggested that both nonactivated (n-PRP) and activated autologous (a-PRP) PRP can be used to treat AGA, we did not find any study investigating the use of homologous PRP (h-PRP) for this purpose. Also, to the best of our knowledge, there are no studies comparing the efficacy of h-PRP, a-PRP, or n-PRP on AGA therapy. The aim of this study was to compare the increase in hair density, average number of platelets, complications, preparation, and duration of application in the treatment of AGA using a-PRP, n-PRP, and h-PRP. Between 2014 and 2015, we studied male patients who had experienced increased hair loss in the last year. Patients were divided into three groups: Group 1 received n-PRP, Group 2 received active PRP, and Group 3 received h-PRP. For Group 1, PRP was prepared by a single centrifugation prepared from the patient's own blood. For Group 2, the PRP was prepared from the patient's own blood, but a second centrifugation was applied for platelet activation with calcium chloride. For Group 3, the PRP was prepared from pooled platelets with the same blood group as the patient from the blood center. PRP was injected at 1, 2, and 6 months. The hair density (n/cm(2)) of each patient before and after injection was calculated. Each patient was assigned a fixed evaluation point at the time of application to calculate hair density. At 2, 6, and 12 months after the first treatment, the increase in hair density was calculated as 11.2, 26.1, and 32.4%, respectively, in Group 1; 8.1, 12.5, and 20.8%, respectively, in Group 2; and 16.09, 36.41, and 41.76%, respectively, in Group 3. The increase in hair density was statistically significantly greater in Group 1 than in Group 2 and more so in Group 3 than in both groups among all controls (p < 0.05). The efficacy of both PRPs was determined in AGA treatment in our study. However, it was determined statistically that the increase in hair density with h-PRP was greater than with autologous PRP groups. We believe that h-PRP therapy can be used in patients with AGA presenting with hair loss.Necmettin Erbakan University, Department of Scientific Research projects [161218022]The authors thank Mehmet Uyar, MD, for his statistical analysis support.

Giant serous microcystic pancreas adenoma
No full textSerous cystadenomas are rare tumors comprising 1-2% of exocrine pancreas tumors. They are mostly known as benign conditions but malign transformation as serous cystadenocarcinoma is also reported. It is usually seen in females. Non-specific symptoms, such as abdominal pain or symptoms due to mass affect, are usually seen. A 64-year old female patient was investigated for abdominal pain. Physical and laboratory findings were normal. Abdomen ultrasonography confirmed an 11x9.5 cm solid cystic lesion and abdomen computed tomography scan confirmed a 12x11 cm lobulated cystic solid lesion which had central cystic necrotic areas extending from liver hilus inferiorly. Fine needle biopsy confirmed benign cytology and trucut biopsy of the pan creatic mass reported chronic inflamation. Nevertheless, this mass could have malignant contents and transformation potential. A laparatomy was decided due to patient’s symptoms and mass effect. Due to vascular invasion of the tumor, Whipple procedure was performed. The pathology report confirmed serous microcystic adenoma. These rare tumors are usually benign but pre-operative malignity criterias are not identified. There are few differential diagnostic tools for excluding malignity. We suggest surgical resection as best treatment approach for selected cases
