Determining Hopelessness Levels and Related Factors in Veterinary Students.

This study addresses the level of hopelessness experienced by last-year students at a faculty of veterinary medicine. Moreover, it identifies the factors behind this emotion. A face-to-face questionnaire was administered to 238 last-year students from 2017 to 2021. The questionnaire included questions about sociodemographic and other characteristics, along with the Beck Hopelessness Scale. Data analysis included descriptive statistics, factor analysis, and chi-square tests. The findings suggested that nearly 60% of the respondents experienced hopelessness. The analysis also revealed a significant relation between hopelessness levels and variables such as year, gender, expected time of first employment, and psychological status. The results suggested that the current state of mental health is worrying for the veterinary faculty students and therefore for the future veterinarians. For this reason, it can be argued that steps to be taken towards a solution in the veterinary education periods are required.

Evaluation of the effects of vitamins C and E on experimental orthodontic tooth movement.

Background. This experimental study aimed to assess the effects of Vitamins C and E on orthodontic tooth movement. Methods. Fifty-one male Wistar albino rats were divided into six groups: five appliance groups and one control group. The appliance groups had an orthodontic appliance consisting of a closed-coil spring ligated between the maxillary incisor and maxillary first molar (50 g). Vitamin E and C (150 mg/kg) were injected intraperitoneally per day in the first and second groups, respectively. Vitamins E and C (20 µL) were locally injected into the periodontal gap of the moving teeth in the third and fourth groups, respectively, once every three days. No vitamin was injected in the last (fifth) appliance group.The experimental period was 18 days. Histological and biochemical (alkaline phosphatase, osteocalcin, and NTx levels) evaluations of the samples were performed, and maxillary incisor‒molar distance was measured before and after the experiment. Results. The amount of tooth movement was similar in the appliance groups. All the vitamin groups showed significantly increased osteoblastic activity, while those treated with systemic vitamins exhibited significantly increased numbers of collagen fibers on the tension side compared to the appliance control group (P<0.05). Conclusion. Vitamin C and E supplements positively affected bone formation on the tension side of the teeth during experimental orthodontic tooth movement.

Infrahyoid Flap, a Convenient Alternative for Reconstruction of Tongue and Floor of Mouth Defects: Case Series.

OBJECTIVE: The aim of this study was to share our clinical experience with the neurovascular myofasiocutan infrahyoid flap (NMIHF), which was used for the reconstruction of the defects after oral cavity cancer surgery. METHODS: Records of five patients who were diagnosed with oral cavity cancer and underwent tumor resection, neck dissection, and defect reconstruction with NMIHF between 2012 and 2017 were analyzed retrospectively. RESULTS: The infrahyoid flap was used in five patients: four males and one female. The mean age of patients was 61.8 years. Four patients underwent tumor resection and bilateral level I-III neck dissection, whereas one patient underwent tumor resection and unilateral level I-III neck dissection. NMIHF was used for the reconstruction of the defects during the same procedure in all the patients. Mean post-operative follow-up was 30.6 months. Partial skin necrosis was observed in two patients, but none of the patients showed total necrosis of the flap. Postoperatively, oral intake was initiated after an average of 12 days in all patients. For two patients who required post-operative radiotherapy (RT), the treatment was started after an average of 50 days. CONCLUSION: NMIHF does not prolong operation time and does not cause additional scar in the neck, and the defect in the donor field can be closed without the use of a graft or flap. This is considered to be a reliable and successful alternative to free flaps for the reconstruction of oral cavity defects.

Increased Atherosclerosis Correlates with Subjective Tinnitus Severity.

The aim of the present study was to investigate whether increased intima media thickness was associated with the severity of subjective non-pulsatile tinnitus and hearing loss. Data of the patients who came to Otorhinolaryngology Department of Isparta Government Hospital with subjective non-pulsatile tinnitus complaint, between January 2012 and June 2013, were evaluated retrospectively. A total of 215 patients were included in the present study. Hearing tests, biochemical analysis, tinnitus handicap inventory (THI), visual analogue scale (VAS) and doppler ultrasonography results of the patients were reviewed and recorded. The patients were classified into two groups as those having an increased intima media thickness and those having a normal intima media thickness. The said groups were compared with respect to age, gender, THI, VAS, hearing test findings and lipid values. Moreover, THI and VAS groups were compared with respect to intima-media thickness. In the group having increased intima-media thickness, THI and VAS average, frequency of hypertension, total cholesterol, low density lipoprotein and triglyceride averages and mean frequencies obtained by hearing test were significantly higher. Comparison of THI and VAS groups showed that intima-media thickness was significantly different between those having a mild tinnitus and those having a severe tinnitus. Increased intima-media thickness was associated with the severity of subjective non-pulsatile tinnitus and hearing loss. For this reason, the carotid system should be examined in subjective non-pulsatile tinnitus patients.

The relation of radiation-induced pulmonary fibrosis with stress and the efficiency of antioxidant treatment: an experimental study.

BACKGROUND: Radiation-Induced Lung Injury has 2 components: radiation pneumonitis and radiation fibrosis. The pulmonary fibrosis has no known efficient treatment. The purpose of this study was to study the relationship between the oxidant/antioxidant status and pulmonary fibrosis in rats having radiation induced pulmonary fibrosis and to study the antioxidant effects of pentoxifylline, vitamin E, and vitamin C in the treatment of pulmonary fibrosis. MATERIAL AND METHODS: The study rats were divided into 5 groups: Thoracic RT + vitamin E+ Pentoxifylline for group 1, Thoracic RT + vitamin C + Pentoxifylline for group 2, Thoracic RT + vitamin C + vitamin E + Pentoxifylline for group 3, and Thoracic RT + Pentoxifylline for group 4, and group 5 was the control group. RESULTS: When groups are evaluated in pairs, significant differences between group 1 and 2, group 1 and 4, and group 1 and 5 were determined (p: 0.002, p: 0.002, p<0.001, respectively). No significant difference was determined between group 1 and 3 (p: 0.161). No significant difference was determined between group 2 and group 3, 4, and 5 (p: 0.105, p: 0.645, p: 0.234, respectively). There was no significant difference between group 4 and 5 (p: 0.645). CONCLUSIONS: The combination of vitamin E and pentoxifylline is efficient in preventing radiation-induced lung fibrosis. The additional benefit of vitamin C, which is added to this combination to increase the antioxidant activity, cannot be shown. It would be useful to investigate the combination of vitamin E, pentoxifylline, and other non-enzymatic antioxidants.

Increased plasma neopterin and hs-CRP levels in patients with endemic fluorosis.

Although fluoride induced inflammatory reactions have been shown in animals and in vitro humans, there are few studies about fluoride induced inflammatory reactions in human beings at clinical setting. We aimed to measure the plasma neopterin, a marker of activation of the monocyte/macrophage system, and high sensitivity C-reactive protein (hs-CRP) levels in patients with endemic fluorosis to investigate the possible role of inflammatory processes (monocyte/macrophage activity) in the underlying pathophysiology of fluoride toxicity at clinical level. Plasma neopterin and hs-CRP levels were determined in endemic fluorosis patients and control subjects. Plasma neopterin levels were significantly higher among patients with endemic fluorosis when compared with control group (2.40 ± 0.66 vs. 1.63 ± 0.27 ng/mL respectively; p < 0.001) and plasma hs-CRP levels were also significantly higher among patients with endemic fluorosis when compared with control group (2.41 ± 1.23 vs. 1.93 ± 0.64 mg/L respectively; p < 0.001). Plasma neopterin levels were positively correlated with urine fluoride levels (r = 0.67, p < 0.001) and serum hs-CRP levels were positively correlated with urine fluoride levels (r = 0.36, p < 0.001). We have found that plasma neopterin and hs-CRP levels are increased in patients with endemic fluorosis. We have concluded that inflammation play an important role in the pathophysiology of fluoride toxicity in patients with endemic fluorosis.

Plantar pitted keratolysis: a study from non-risk groups.

Pitted keratolysis is an acquired, superficial bacterial infection of the skin which is characterized by typical malodor and pits in the hyperkeratotic areas of the soles. It is more common in barefooted people in tropical areas, or those who have to wear occlusive shoes, such as soldiers, sailors and athletes. In this study, we evaluated 41 patients who had been diagnosed with plantar pitted keratolysis. The patients were of high socioeconomic status, were office-workers, and most had a university degree. Malodor and plantar hyperhydrosis were the most frequently reported symptoms. The weight-bearing metatarsal parts of the feet were those most affected. Almost half the women in the study gave a history of regular pedicure and foot care in a spa salon. Mean treatment duration was 19 days. All patients were informed about the etiology of the disease, predisposing factors and preventive methods. Recurrences were observed in only 17% of patients during the one year follow-up period. This study emphasizes that even malodorous feet among non-risk city dwellers may be a sign of plantar pitted keratolysis. A study of the real incidence of the disease in a large population-based series is needed.

Association of laryngopharyngeal manifestations and gastroesophageal reflux.

The aim of this study was to investigate the prevalence of gastroesophageal reflux disease (GERD) in patients with laryngopharyngeal symptoms, the relationship between laryngopharyngeal reflux (LPR) and Helicobacter Pylori infection and treatment response to proton pump inhibitors. Forty-five patients with suspected gastroesophageal reflux diseases related symptoms (sore throat, throat burning, throat clearing, globus sensation, cough, halitozis, dysphonia, dysphagia, postnasal dripping, vocal fatigue, and sputum) were included in this study. For pre-therapeutic and post-therapeutic comparison, symptoms and laryngological findings were graded on a 4-point scale. The patients underwent upper gastrointestinal system endoscopy. During endoscopy, antral biopsies from the stomach were obtained to detect H. Pylori. Antireflux medication with proton pump inhibitors (PPI) and H. Pylori eradication therapy if present were prescribed to the patients. The improvement in symptoms and laryngological findings were evaluated after treatment. By means of esophagogastroduodenoscopy (EGD), reflux was detected in only 11% of patients. But there can be reflux patients other than the detected ones. Although, H. Pylori was present in 62% of patients, no correlation was found between H. Pylori positivity and symptoms. All patients responded well to antireflux treatment and H. Pylori eradication therapy. Laryngopharyngeal symptoms and findings can be predictors of gastroesophageal diseases when response to reflux treatment is taken into account.

[Case report: psoas abscess due to brucellosis]. / Olgu raporu: brusellozise bagli psoas apsesi.

Skeletal system involvement is relatively a common complication of human brucellosis. However, muscular involvement is less frequent, and particularly psoas abscess is always secondary to spondylitis. In this case report, psoas abscess formation in a 70 years old female brucellosis patient complicated with spondylitis on vertebral corpus, has been presented.
