Abstract
Cutaneous hemangiomas are the most common tumors of infants and children. Although they frequently resolve spontaneously, approximately 5% produce complications such as bleeding, infection, consumption coagulopathy and unesthetic appearance. Various methods of treatment are described for these complicated hemangiomas. We used a new type of treatment for complicated cutaneous hemangiomas as intralesional bleomycin (BLM) injection, for the first time in the literature. This agent produced extensive fibrosis and spontaneous resolution of hemangiomas. Fourteen patients with complicated hemangiomas (twelve capillary and two cavernous) have been treated with this method during a three-years period. Of these fourteen patients, five had bleeding, three had infection, one had ulceration, and five had unesthetic appearance and continued rapid growth. Lesions of three patients were completely excised after only one BLM injection. In the other eleven patients lesions regressed 60-100% during 6-14 months with two to three BLM injections. We believe that intralesional BLM injection is simple, and very useful for treatment of complicated cutaneous hemangiomas.

Abstract
BACKGROUND In this study, we investigated the inhibitory effects of desflurane and sevoflurane on oxytocin-induced contractions of isolated human myometrium. METHODS Following delivery of the infant and placenta, a small segment of myometrium was excised from the upper incisional surface of the lower uterine segment and 20 strips, randomly assigned into two groups (n = 10), were obtained from 20 non-laboring term parturients. The study protocol consisted of a 60-min period of spontaneous contractions, control recording with oxytocin 2 x 10(9) m (10-min period), washout interval of 10 min, volatile administration (three times per 15-min period) of 0.5, 1 and 2 minimum alveolar concentration (MAC), response to oxytocin (10-min period), a further washout interval (10-min period) and subsequent control recording with oxytocin without anesthetics. RESULTS After oxytocin administration, the frequency and amplitude of contractions increased (P < 0.05) and the duration decreased (P < 0.05). The frequency and amplitude of contractions induced with oxytocin decreased significantly at 0.5, 1 and 2 MAC of desflurane and sevoflurane (P < 0.05). The amplitude of contractions was significantly different at 1 MAC between the two groups (P < 0.05). The duration of contractions at 2 MAC decreased in both groups (P < 0.05). CONCLUSIONS Desflurane and sevoflurane at 0.5, 1 and 2 MAC inhibit the frequency and amplitude of myometrial contractions induced with oxytocin in a dose-dependent manner. However, desflurane inhibits the amplitude less than sevoflurane at 1 MAC. We suggest that 0.5 MAC of both agents and 1 MAC of desflurane may be safely used in the presence of oxytocin following delivery of the infant and placenta during Cesarean section without fear of uterine atony and hemorrhage.

Abstract
This report describes a case of massive cystic tetrathyridiosis in a four-year-old female dobermann. The larvae were distributed in both the peritoneal and pleural cavities, as well as in the lumen of the small intestine along with adult Mesocestoides species. These parasites were identified as tetrathyridia. Numerous cysts were dispersed on the peritoneal, pleural and mesenteric surfaces. The same cysts were seen both on subcapsular surfaces and within sections of the spleen, liver, kidneys and lungs. Histopathological examination also revealed characteristics of tetrathyridium of Mesocestoides species.

Abstract
Carcinoma in the thyroglossal duct remnant is relatively uncommon. Since the first report by Uchermann (1915), more than 150 cases of carcinoma have been reported, and the majority have been papillary thyroid carcinomas (Li Volsi et al., 1974; McNicol et al., 1988). In this report, we present a case of papillary carcinoma in the thyroglossal duct with a normal thyroid gland.

Abstract
This study was conducted in order to determine the prevalence and fertility of hydatid cysts in sheep in Kirikkale, Turkey. A total of 3.2% of 553 lambs and 50.9% of 1320 adults were found to be infected with hydatid cysts. The most common locations of cysts were in the liver and lung. Liver cysts tended to be more fertile than lung cysts (81.53% v. 76.47%), though the difference was not significant. The mean number of viable protoscoleces in the liver and lung cysts were 12,400 and 5,800, respectively. In general, 1-10 cysts were found in liver (51.8%) and lung (64.7%). The findings of this study indicate that hydatid cysts are common in sheep and the fertility rate of cysts is quite high. Sheep play an important role in the life cycle of Echinococcus granulosus in this region.

Abstract
BACKGROUND The aim of this study was to investigate the recovery properties of desflurane and sevoflurane in patients undergoing elective surgery, according to the gender differences. METHODS In the study, 160 ASA class I-II patients aged between 20 and 60 years were included. The patients were assigned into two groups according to their gender, and these groups were randomly divided into two groups according to a selected volatile anaesthetic agent. Intraoperative bispectral index, time of postoperative achievement for end-tidal concentrations of volatile agents to decline 50% (ET-AA%50), time for extubation, time for eye opening and orientation, and time for bispectral index values to reach control values were recorded. Aldrete scores and error points of a delayed memory recall test were determined. RESULTS Desflurane groups had a shorter ET-AA%50 time, extubation and eye-opening time in male and female patients compared to the sevoflurane groups, and these results were statistically significant (P < 0.05). In both the desflurane and sevoflurane groups, ET-AA%50 time, extubation and eye-opening time were shorter in male patients than in female patients, and these results were also statistically significant (P < 0.05). There were no significant differences among the groups in terms of Aldrete scores and error points of delayed memory recall test (P > 0.05). CONCLUSION In conclusion, early recovery time was shorter in male patients compared to female patients in both the desflurane and sevoflurane groups. Additionally, in the desflurane groups it was shorter in the sevoflurane groups for both genders.

Abstract
BACKGROUND We studied the inhibitory effects of desflurane and sevoflurane on oxytocin-induced contractions of isolated gravid rat myometrium. METHODS Twenty strips were obtained from rats and these were randomly assigned into two groups. The effects of desflurane and sevoflurane were evaluated by treating strips with oxytocin alone 2x10-9 M or with oxytocin after desflurane and sevoflurane at 0.5, 1, and 2 MAC. RESULTS Oxytocin significantly increased the amplitude and duration of contractions (P< 0.05), but it did not increase the frequency. The duration (84%, 79%), amplitude (90%, 84%) and frequency (88%, 75%) were inhibited at 2 MAC of desflurane and sevoflurane, respectively. CONCLUSION These results suggest that the in vitro application of desflurane and sevoflurane similarly inhibit oxytocin-induced myometrial contractions of gravid rat in a dose-dependent manner.

Abstract
PATIENT Female, 45 FINAL DIAGNOSIS: Neuroendocrine tumor Symptoms: Abdominal pain Medication: - Clinical Procedure: - Specialty: Gastroenterology and Hepatology. OBJECTIVE Unusual setting of medical care. BACKGROUND Neuroendocrine tumor of the ampulla of Vater is extremely rare and is generally a low-grade endocrine cell tumor. The merits of radical vs. local resection remain uncertain. CASE REPORT A 45-year-old female patient presented with abdominal pain lasting for 2 months. Papilla that was tumor-like macroscopically was seen in the second part of the duodenum in endoscopic retrograde cholangiopancreatography. Biopsy was histologically confirmed as a low-grade neuroendocrine tumor. No lymphadenopathy or visceral metastasis was found on an abdominal CT scan, In-111 octreotide scan, and EUS. The ampulla was removed by endoscopic snare papillectomy. All margins of resection were negative for tumor. CONCLUSIONS Endoscopic snare papillectomy may be the first step in the management of neuroendocrine tumors of the ampulla of Vater in high-risk surgical candidates and selected patients such as those with a well differentiated, low-grade, small tumor without regional/ distant metastasis. However, it can also be used in younger patients who wish to avoid surgical resection.

Abstract
OBJECTIVE This study retrospectively compared the clinical and radiological outcomes of patients with bilateral developmental dysplasia of the hip who underwent either a single-stage operation (using a Salter innominate osteotomy for one hip and a Pemberton pericapsular osteotomy for the other hip) or a two-stage procedure comprising consecutive operations. METHODS Extensive pre- and postoperative clinical, surgical and radiological examinations were undertaken. RESULTS A total of 63 patients received the single-stage operation (group A), and 55 patients received consecutive operations (group B). There were no significant between-group differences in acetabular index or centre-edge angle correction. Group A had significantly reduced anaesthetic exposure, duration of hospitalization, blood transfusion volume, antibiotic costs and hospitalization costs. Group A also had a lower rate of surgical complications and avascular necrosis than group B. CONCLUSIONS The single-stage surgical procedure was more economical and allowed more rapid recovery than two consecutive operations. The surgical and anaesthesia team must be highly proficient in order to perform single-stage operations successfully.

Abstract
OBJECTIVE Prostacyclin (PGI2) has been shown to inhibit the expression of pro-inflammatory and pro-fibrotic mediators in pulmonary fibrosis. In this study, we aimed to test the preventive effects of intraperitoneally administered iloprost, a stable PGI2 analog, on bleomycin-induced pulmonary fibrosis in rats and to compare the effects of iloprost with the effects of methyl-prednisolone, a traditional therapy. METHODS Rats were randomly allocated into four groups: 1. Saline alone (n=6); 2. Bleomycin+placebo (n=7); 3. Bleomycin+methyl-prednisolone (n=7); 4. Bleomycin+iloprost (n=7). Fibrotic changes in the lungs were demonstrated by analyzing the cellular composition of bronchoalveolar lavage fluid, histological evaluation and lung hydroxyproline content. RESULTS Fibrosis was made in the lungs of rats by bleomycin experimentally. Fibrosis scores in the methyl-prednisolone and the iloprost groups were significantly lower than in the placebo group (p<0.05). Furthermore, the score of the iloprost group was significantly lower than the score of the methyl-prednisolone group. The hydroxyproline content was significantly less in the methyl-prednisolone and the iloprost groups (p<0.05). In the placebo group, the neutrophil percentage in bronchoalveolar lavage was significantly higher than in the other groups, whereas the macrophage percentage in placebo group was significantly lower (p<0.05). CONCLUSION Iloprost has protective effect on the pulmonary fibrosis induced by bleomycin and it may be more effective in decreasing fibrotic changes than methyl-prednisolone.

Abstract
In this study we presented 92 cases with regional lymphadenitis (over 1 cm in diameter) which was caused by BCG vaccination generally performed a few days after birth. The patients were divided into four therapy groups. In group I, the lymphadenitis in 26 cases was excised totally by a surgical operation and they improved in a median period of four weeks (average: 4.4). No therapy was applied in 33 patients constituting group II and their periods of improvement were 28 weeks (average: 29.1). Sixteen cases in group III were given isoniazid (INH) 10 mg/kg for six months in addition to total surgical excision and their healing period was 4.5 weeks (average: 4). Seventeen cases in group IV were administered only INH for six months and the median improvement period was found to be 27 weeks (average: 28.2). The statistical differences in terms of the improvement periods between groups I and III, and groups II and IV were found to be insignificant (p greater than 0.05) but these differences were significant between groups I and II, groups I and IV, groups II and III, and groups III and IV (p less than 0.05). These results show that spontaneous healing is possible. Total excision is the best therapy for BCG lymphadenitis in suppurative forms and INH has no effect in shortening the therapy period.

Abstract
Our purpose was to investigate the direct depressant effects of desflurane and sevoflurane at 0.5, 1 and 2 minimum alveolar concentrations (MAC) on spontaneous contractions of isolated gravid rat myometrium. Ten gravid, albino Wistar rats, weighing 240-310 g and at 19-20 days' gestation were used. Sixty myometrial strips were obtained from 10 rats, and randomly assigned into six groups of 10. After obtaining spontaneous myometrial contractions in de Jalon solution for 45 min, 0.5, 1 or 2 MAC of desflurane or sevoflurane were continuously bubbled in the bath for 15 min and myometrial contractions evaluated during the last 10 min. Desflurane 0.5 MAC did not affect duration or amplitude of spontaneous contractions, but frequency was significantly decreased (P < 0.05). Duration, amplitude and frequency were all significantly decreased by desflurane 1 and 2 MAC (P < 0.05). Sevoflurane did not affect duration, amplitude or frequency at 0.5 MAC, but amplitude and frequency were significantly decreased at 1 MAC and all were significantly decreased at 2 MAC (P < 0.05). The frequency of contractions was decreased 21.2% with 1 MAC desflurane versus 17.1% with 1 MAC sevoflurane. The amplitude and frequency of contractions were decreased 48.2% and 48.7% with 2 MAC desflurane versus 58.9% and 49.3% with 2 MAC sevoflurane, respectively. We suggest that due to tocolytic activity, desflurane and sevoflurane can be useful in non-obstetric surgery during pregnancy.

Abstract
In this study orchiopexy was performed in 30 Sprague-Dawley rats in order to compare traumatic effects of surgical and autologous fascial suture materials on testicular histology. Abscess formation was observed in 72.7% of the chromic, in 36.3% of the nylon, and in 18.1% of the vicryl fixed groups. There were no abscess formations in the dartos and autologous fascial fixed group. Examination of the testes revealed complete absence of spermatogenesis in the chromic fixed group. Spermatogenesis was normal, 72% in the vicryl, 18.1% in the nylon, 90.9% in the dartos and autologous fascial suture fixed groups. Antisperm antibody was not observed in any rat sera. We consider that it is preferred to use dartos pouch fixation. If necessary, it is advisable to use autologous fascial suture materials.

Abstract
Four cats were presented with respiratory signs and first-stage larvae of Aelurostrongylus abstrusus were found in faecal samples. Anthelmintic treatment was given to the infected cats and venous blood gases were analysed during the treatment period. Blood gas analysis suggested hypoventilation and respiratory acidosis in infected cats. Hypoventilation may be the result of airway obstruction by adults and larvae in respiratory bronchioles and the alveolar canals. The blood gas values had returned close to the physiological range by two months after treatment. Assessment of respiratory acidosis may aid development of additional treatment methods in cats infected with A. abstrusus.

Abstract
To investigate the effects of unilateral testicular torsion on both testes, we studied 4 groups of adult male New Zealand rabbits using sham operation, torsion and detorsion after one or eight hours and permanent torsion. Bilateral orchiectomy was performed 9 weeks after the operation, and testicular weights, Johnsen scores, quantitative analyses, tubular diameters were calculated and histopathologic diagnosis was determined. Testicular weights, Johnsen scores, spermatid counts and tubular diameters were all decreased in torsioned testes depending on the duration of torsion. The contralateral testes showed no significant change in any of the study groups when compared with the control group.

Abstract
The purpose of the study was to compare the clinical activity of remifentanil or alfentanil under propofol sedation with regard to respiratory rate, sedation and recovery rate when used for outpatient endometrial biopsy. Patients were randomized to receive intravenously either bolus remifentanil 0.4 microgram/kg and propofol 1 mg/kg in the remifentanil group (n = 30), or bolus alfentanil 20 micrograms/kg and propofol 1 mg/kg in the alfentanil group (n = 30). Patients were monitored for heart rate, systolic and diastolic arterial pressure, peripheral O2 saturation (SpO2), respiration rate, and Aldrete sedation score. Pulse oximetry was used to monitor heart rate and SpO2 during endometrial biopsy. Apnoea was observed in five patients from the remifentanil group, and in three patients from the alfentanil group. The groups did not differ with regard to apnoea incidences. Times were recorded for orientation and Aldrete score > 8, and were similar between the two groups (13.20 +/- 3.64 min and 14.0 +/- 3.87 min in the remifentanil group, 14.7 +/- 3.64 min and 15.9 +/- 3.15 min in the alfentanil group, respectively). The sedative and analgesic combination of remifentanil-propofol does not offer any advantages compared with a combination of alfentanil-propofol with regards to respiration and recovery during sedation for outpatient endometrial biopsy.

Abstract
Two rare cases of mesenteric fibromatosis are presented. The first patient had a right upper quadrant mass and colicky abdominal pain. The tumor originated from the mesentery of the colon and it infiltrated the gallbladder, cystic duct, and the liver. The second patient had severe hematemesis and melena. The origin of the tumor, which infiltrated 3/4 part of the stomach, the gastrohepatic ligament, the first part of the duodenum, and the liver could not be determined. In the first patient, partial colectomy and cholecystectomy were performed and the liver lesion was completely excised. The second patient underwent subtotal gastrectomy and left lobectomy of the liver. The first part of the duodenum was excised. Gastrojejunostomy was performed. No recurrence was recorded in either patients during 16 and 13 months follow-up, respectively. In this report, diagnostic aids, differential diagnosis and treatment of this rare disease are discussed.

A newborn baby boy weighing 3100 g was found to have a pinky red solid mass 3 x 2.5 x 2 cm arising from the anterior ridge of the maxilla. This caused difficulty in feeding, and looked ugly. The mass was excised under local anaesthetic when he was 2 days old and histological examination showed congenital epulis. He also had a stage II congenital goitre. His hypothyroidism was treated with L-thyroxine sodium and he was well with no sign of recurrence of the tumour at the age of 1 year.

Abstract
OBJECTIVE This study was conducted to evaluate the protective effect of dexmedetomidine on nephrotoxicity and the mechanism of renoprotection following vancomycin-induced nephrotoxicity in rats. METHODS Thirty-two albino Wistar rats were divided into four groups. The control group received intraperitoneal (IP) physiological saline solution, the vancomycin (VMC) group received IP 200 mg/kg vancomycin, the dexmedetomidine (DEX) group received IP 5 µg/kg dexmedetomidine, and the vancomycin and dexmedetomidine (VMC+DEX) group received IP 200 mg/kg vancomycin followed by IP 5 µg/kg dexmedetomidine 20 min after the vancomycin injection. On the 8th day of the experiment, histopathological and biochemical parameters were assessed. RESULTS Creatinine levels were significantly higher in VMC and VMC+DEX groups. The endothelin-1 level was significantly higher in VMC group. Nitric oxide levels were statistically lower in VMC and VMC+DEX groups. Histopathologic assessments revealed that the extent of renal damage was significantly higher in group VMC (n = 4 with damage of Grade 3) compared to group VMC+DEX (n = 0 with damage of Grade 3). CONCLUSION It was determined that dexmedetomidine can reduce the extent of renal damage by preventing the elevation of vasoconstrictor agents (Tab. 2, Fig. 1, Ref. 36).

Abstract
A 23-year-old, male patient previously operated on four times for a recurring, benign, paranasal mass was admitted to our clinic with pain and swelling under the knee. Physical and radiological examination revealed a malignant process. The histopathological examination of the fine-needle biopsy specimen of the tibia was a malignant mixed tumor. Then. en-bloc resection, free fibular grafting, and fixation with blade plate was performed for one-third of the tibia, conserving the knee joint. Recurrences and metastasis were not observed after surgery and radiotherapy.

Abstract
Abstract
Study question
Is there any difference in this technique(swim-in) according to clinical results in ICSI cycles?
Summary answer
Fertilization rates are significantly better with this new technique(swim-in). There is no difference in pregnancy and ongoing pregnancy rates between swim-in and DGS techniques.
What is known already
Sperm separation is crucial in assisted reproductive technologies, based on different principles like migration, filtration, or density gradient centrifugation techniques. However, there are some studies that centrifugation steps and using gradient solutions may increase sperm DNA fragmentation. On the other hand, multiple contacts to different plastic surfaces such as pipettes, plastic tubes, etc., and also pipetting the ejaculate in sperm preparation may have detrimental effects. The ideal sperm separation technique should be non-invasive, not time-consuming, easy, and cost-effective, not cause sperm damage or non-physiological alterations of the separated sperm cells, eliminate dead spermatozoa and other cells, including leukocytes.
Study design, size, duration
This is a prospective randomized study between 01/02/2019...01/01/2021. Sperms were prepared either with this new technique that we call “swim-in”(n = 359) or with density gradient centrifugation(n = 404) before microinjection (ICSI). Fertilization rates, clinical pregnancy rates, and on-going pregnancy rates were compared between groups. Sperm motility is less than%20 patients are not included in the study. t-test and Chi-square test used. p < 0.05 significant.
Participants/materials, setting, methods
For this new centrifugation free technique(swim-in), a Braun injector, 21G green needle, and sperm washing medium are used. First, we pulled a 0.5 ml sperm wash medium in a Braun injector. After sperm liquefaction, we put Braun injector with the needle in the sperm cap perpendicularly and waited 30 minutes at 37-degree Celcius. Sperms swam through the needle to the injector used for ICSI. For DGC sperms were prepared according to the 2015 WHO manual. Main results and the role of chance: We try to make a centrifugation-free, gentle, cost-effective, and easy sperm preparation technique and called it a swim-in technique. Groups were comparable according to mean age, collected oocyte numbers, and oocyte maturation ratios. Fertilization rates are%73,2(1786/2438) vs%66,9(2167/3237) respectively for swim-in and DGC groups. Clinical pregnancy rates are%45,1 vs%42,3 respectively for swim-in and DGC groups. On-going pregnancy rates are%41,5 vs%39,6 for swim-in and DGC respectively. There is a significant difference between the two techniques according to fertilization rates but no difference according to clinical pregnancy and ongoing pregnancy rates.
Limitations, reasons for caution
Sperms can move by their own motility from ejaculate to the sperm washing medium for that reason with severe sperm problem patients are not suitable for this technique.
Wider implications of the findings: This technique is centrifugation free so there are no detrimental g-forces. The needle used may mimic the physiological environment like Uterine Tube. Alternative sperm washing mediums like follicular fluid or chemical attractor progesterone rich medium can be used.DNA fragmentation rates and live birth rates should be established for future aspect.

Abstract
The histogenetic origin of salivary gland tumours is not clear. In normal tissues smooth muscle actin (SMA) is expressed in myoepithelial cells, CK14 immunoreactivity is seen in myoepithelial and basal cells and CK10 in keratinized squamous epithelium. In this study, we examine the immunophenotypic properties of salivary gland tumours in order to obtain further insight into their histogenesis. 30 cases of salivary gland tumours (18 pleomorphic adenomas, 8 Warthin's tumours, 2 basal cell adenomas, 2 acinic cell carcinomas) were included in our study. Cytokeratin (CK) 10, CKI4, CKI7, CK18, CK 19, and smooth muscle actin (SMA) immunostains were applied to the sections. Immunoreactivities were detected and the statistical significance was evaluated by chi square test. SMA was not detected in Warthin's tumour (p < 0.0001). CK14 was found in all tumours except acinic cell carcinomas (p < 0.0001). CK10 immunoreactivity was observed in 5 Warthin's tumour. In conclusion, pleomorphic adenomas and basal cells adenomas originate from stem cells. Immunophenotypic profile of Warthin's tumour is suggestive of an embryological remnant origin.
