Evaluation of the effects of the surgical removal of impacted third molars on the emotional state of individuals with Beck depression inventory.

AIMS: In this study, using Beck depression inventory (BDI), we aimed to determine alterations in the emotional state of patients who had impacted third molars (M3) extracted owing to postoperative pain, edema, and trismus.In this prospective clinical trial, which was conducted at Tokat Gaziosmanpasa University, Faculty of Dentistry, Department of Maxillofacial Surgery Clinic, we studied 60 patients (30 males and 30 females), who were 18-47 years old (the mean of 25.6 years of age). The patients with M3 with moderate preoperative pain intensities, edema, and maximal mouth opening (MMO) data were recorded, and BDI was applied to determine their emotional states. The patients were re-evaluated using BDI to detect alterations in their emotional state owing to pain intensity, edema, and trismus on postoperative second and seventh day. SUBJECTS AND METHODS: Descriptive statistical analysis, Chi-square, and independent t-test were utilized to interpret the obtained data. RESULTS: According to our findings, a statistically significant relationship was observed between BDI scores and gender on the second postoperative day (P = 0.004), and between MMO and BDI scores on the second and seventh postoperative day (P = 0.012, P = 0.045). Pain intensity scores on the postoperative sixth hour and seventh day were significantly correlated with BDI scores on the postoperative second and seventh day (P = 0.000/ P = 0.000/P = 0.002/P = 0.004/P = 0.010/P = 0.017/P = 0.001/P = 0.000). CONCLUSIONS: Our results suggest that the pain and trismus owing to the M3 surgery were significantly correlated with an increase in the postoperative BDI scores.

Mediastinitis as complication of odontogenic infection: A case report.

Odontogenic infections are one of the most common dental problems, which affect 80%-90% of the population. Untreated odontogenic infections can cause life-threatening complications such as necrotizing fasciitis, descending necrotizing mediastinitis, internal jugular vein thrombosis, cavernous sinus thrombosis, carotid artery pseudoaneurysm or rupture, and systemic inflammatory response syndrome. This report aims to present a mediastinitis case, in a 22-year-old healthy male patient, which originated from an odontogenic infection. The patient was hospitalized because of worsening general health status, despite the antibiotherapy. Computed tomography (CT) scan revealed that periapical abscess was spreading to the mediastinum through retropharyngeal space. The patient was successfully treated by IV antibiotherapy, transcervical drainage, and extraction of tooth.

Does immune activation continue during an attack-free period in familial Mediterranean fever?

Although some information is available regarding immune activation in familial Mediterranean fever (FMF), little is known about either peripheral blood T cell activation marker expression or the T cell proliferative response to phytohaemagglutinin (PHA). In the present study, we aimed to investigate the percentages of peripheral blood lymphocyte subsets, T cell expression of cellular activation markers (CD25, CD69, HLA-DR), the T cell response to PHA and serum levels of soluble interleukin-2 receptor (sIL-2R) and interleukin (IL)-10 in patients with FMF. Forty patients with FMF were enrolled into the study. Control groups were sex- and age-matched and consisted of 20 healthy blood donors and 15 patients with inactive Behcet's disease. The patients with FMF in an attack period had higher levels of sIL-2R than those in an attack-free period, and also in comparison with both control groups. The levels of sIL-2R were also found to be higher in patients with FMF in an attack-free period than those in both control groups. The mean levels of IL-10 were found to be lower in patients with FMF in an attack-free period than those in an attack period and were also lower than those in the healthy controls. In an acute attack period, the absolute counts of CD3+HLA-DR+, CD4+CD69+, CD8+CD25+ and CD8+CD69+ T cells in peripheral blood samples were also higher than those in both control groups. Both the percentages and absolute counts of CD4+CD69+ T cells in peripheral blood samples of patients with FMF in an attack-free period were slightly but significantly higher than those in the healthy controls. In conclusion, our study indicates that the T cell system is abnormally activated in patients with FMF in both the attack and attack-free period and that decreased IL-10 levels may create a tendency to perpetuate subclinical immune activation in the attack-free period.

Rifampicin test in the diagnosis of Gilbert's syndrome.

Gilbert's syndrome (GS) is characterised by the existence of chronic mild unconjugated hyperbilirubinaemia. The value of rifampicin as a provocative test for the diagnosis of GS was evaluated and compared with a fasting test. Twenty-two patients with GS, 15 patients with chronic liver disease and 20 healthy controls were included. Both rifampicin and fasting tests were applied to all subjects. In the fasting test, the subjects were given a 400 calorie/day diet for 24 hours; in the rifampicin test, unconjugated bilirubin levels was measured before and four hours after taking 600 mg of rifampicin. Both tests achieved a significant increase in mean unconjugated bilirubin levels in patients with GS but not in the controls. The sensitivity and specificity of a rifampicin test in the diagnosis of GS were comparable with the fasting test. However, both tests caused a significant increase in unconjugated bilirubin levels in nearly half the patients with chronic liver disease. A rifampicin test may be used in the diagnosis of suspected GS instead of a fasting test, as it is simpler and more practical. However, its specificity for GS is not sufficient, because it also causes an increase in unconjugated bilirubin levels in some patients with chronic liver disease.

Impact of Helicobacter pylori and Giardia lamblia infections on chronic urticaria.

The etiology of chronic urticaria is largely unknown. The role of Helicobacter pylori infection, which is the most important cause of gastritis and peptic ulcer, is not clear in the pathophysiology of chronic urticaria. In this study, we aimed to define the impact of H. pylori on chronic urticaria. Thirty-eight patients who had chronic urticaria of unknown origin and dyspepsia were included in the study. In all patients, standard laboratory tests for detection of urticaria etiology were performed. Mean urticaria symptom scores of patients were carried out. All patients underwent upper gastrointestinal endoscopy. The presence of H. pylori was investigated using urease testing and histopathology. Duodenal fluid aspirated during upper endoscopy was examined for the presence of Giardia lamblia. H. pylori infection was detected in 29 patients. After successful eradication of H. pylori infection, the mean symptom score of patients did not change significantly (2.6 +/- 0.6 vs., 2.4 +/- 0.8). Only one patient had a total disappearance of urticaria symptoms. Out of 38 patients, only one had G. lamblia infection. The results of our study suggest that there is no association between H. pylori infection and chronic urticaria.

Insignificant role of hepatitis G virus infection in patients with liver enzyme elevations of unknown etiology.

Hepatitis G virus (HGV) may cause acute and chronic infection in humans but its role in parenchymal liver injury and chronic hepatitis is obscure. In this study, the importance of HGV was investigated in patients with elevated aminotransferases alanine transaminase/aspartate transaminase (ALT/AST) levels of unknown etiology. We included 56 patients with elevated ALT/ AST levels of unknown etiology and 81 healthy controls in the study. HGV RNA was investigated by the reverse transcription polymerase chain reaction. The other possible causes of transaminase elevation were excluded with detailed biochemical and serologic tests. Liver biopsy was performed on 47 patients for histologic examination. HGV RNA was detected in only two patients (3.3%) and in one control (1.2%). There was no statistical difference between the groups. Liver biopsy revealed minimal inflammatory changes and steatosis in HGV RNA-positive patients. These observations indicated that HGV prevalence is not different from that of the general population in patients with liver transaminases elevation of unknown etiology. The role of this novel virus in the pathogenesis of chronic liver injury of unknown etiology appears insignificant in our geographic area.

Serum leptin levels in patients with nonalcoholic steatohepatitis.

OBJECTIVE: Leptin is a peptide hormone that mainly regulates food intake and energy expenditure of human body. A close correlation between serum leptin levels and the percentage of body fat stores is well known. Nonalcoholic steatohepatitis (NASH) is a common disorder which causes serum liver enzyme elevation. In this study, the serum leptin levels were investigated in patients with NASH to determine a possible role in the pathogenesis and in patients with chronic viral hepatitis to ascertain the effect of hepatic inflammation on serum leptin level. METHODS: Forty-nine patients (38 men, 11 women) with NASH diagnosed by biopsy, 32 patients with biopsy-proven chronic viral hepatitis (21 men and 11 women), and 30 healthy adults (17 men, 13 women) enrolled in the study. Fasting blood samples were obtained, and serum leptin levels were measured by ELISA. Body mass index (BMI) was calculated for all subjects, and serum insulin, C-peptide, and lipoprotein levels were also detected. RESULTS: The mean serum leptin levels (+/-SEM) were 6.62 +/- 0.71, 4.24 +/- 1.0, and 4.02 +/- 0.46 ng/ml in NASH, chronic hepatitis, and the control group, respectively. Mean serum leptin level in the NASH group was significantly higher than those in the other groups tested. BMI was also slightly higher in the NASH group when compared to the other groups (26.7 +/- 0.3, 23.7 +/- 0.6, and 24.6 +/- 0.3, respectively). There was a significant correlation between BMI and serum leptin levels when all the subjects were evaluated together (NASH, hepatitis, and control groups, r = 0.337, p = 0.012) but not in the NASH group when evaluated alone (r = 0.238, p = 0.1). Of the predisposing factors for NASH, obesity was observed in 24% of patients and hyperlipidemia in 67%. Serum cholesterol and triglyceride levels were significantly higher in the NASH group than those in controls (p < 0.05). It has been detected that most of these patients consumed high amounts of fat in their dietary habits. CONCLUSIONS: The serum leptin levels were significantly higher in patients with NASH, while they were not affected by chronic hepatitis. This elevation is out of proportion to BMI of these patients and may be related to hyperlipidemia in most. Elevated serum leptin levels, therefore, may promote hepatic steatosis and steatohepatitis.

The effect of Helicobacter pylori eradication on duodenal gastric metaplasia.

We investigated the incidence of duodenal gastric metaplasia and its response to Helicobacter pylori eradication in patients with duodenal ulcer or erosive duodenitis. Gastric and duodenal biopsies were taken from patients with endoscopically detected H. pylori positive duodenal ulcer or erosive duodenitis, and the presence and extent of duodenal gastric metaplasia was recorded. Patients were given omeprazole 20 mg twice daily for 2 weeks, and amoxicillin 1 g and clarithromycin 500 mg twice daily for 10 days, and then ranitidine for a further 8 weeks. Biopsies were repeated 6 months after the start of treatment. Duodenal gastric metaplasia was initially present in 22 patients (52%) and was more frequent in ulcer patients than in duodenitis patients, but not significantly so (69% versus 45%). After treatment, H. pylori was eradicated in 68% of duodenal gastric metaplasia patients and the duodenum was normal endoscopically in 85% of these patients. Duodenal gastric metaplasia was improved or eliminated in 12/15 H. pylori eradicators (80%) and in 5/7 H. pylori non-eradicators (71%), a non-significant difference. The improvement in duodenal gastric metaplasia appeared to be independent of H. pylori eradication.

Efficacy of omeprazole plus two antimicrobials for the eradication of Helicobacter pylori in a Turkish population.

Omeprazole combined with 2 antimicrobials has been suggested as a first-line option for Helicobacter pylori eradication in recent years. However, controversy exists regarding the efficacy of this protocol. This open-label, prospective clinical study investigated the efficacy of omeprazole-based triple therapy for H pylori eradication in 518 patients with H pylori-positive functional dyspepsia with or without duodenal ulcer. Amoxicillin, macrolides (clarithromycin or roxithromycin), and nitroimidazoles (metronidazole, ornidazole, or tinidazole) were the antibiotics used in the study. Nonulcer patients were randomly assigned to 1 of 8 different treatment protocols and duodenal ulcer patients were randomly assigned to 1 of 4 different treatment protocols consisting of omeprazole (20 mg once daily for nonulcer patients, 20 mg twice daily for ulcer patients for 14 days) with a combination of 2 of the above antimicrobials (for 10 days). H pylori infection was assessed by histologic findings and a rapid urease test before therapy and 4 weeks after therapy ended. Four hundred fifty-nine patients completed their regimens; 327 had functional dyspepsia (180 men, 147 women; median age, 39 years; range, 18 to 70 years) and 132 had ulcers (81 men, 51 women; median age, 40 years; range, 18 to 70 years). Eradication of H pylori was achieved in 58.8% (270 of 459) of all patients, 58.1% (190 of 327) of nonulcer dyspeptic patients, and 60.6% (80 of 132) of duodenal ulcer patients. The eradication rate varied from 47.2% to 69.4% in different treatment protocols. There were no statistically significant differences in eradication rates in any treatment group. All drugs were generally well tolerated in all groups, and no patient discontinued treatment because of side effects. Therapy with omeprazole and 2 antimicrobials for H pylori had limited efficacy in a Turkish population. The reason for these results, which conflict with those of other studies, is not clear. Further investigations of regimens for the eradication of H pylori in our population are necessary.
