Investigation of hearing loss in patients with acute brucellosis by standard and high-frequency audiometry

This study aimed to determine the effect of acute brucellosis on the auditory system. Forty-two patients with acute brucellosis were evaluated clinically, and with serological and audiological tests, before and after treatment. Hearing threshold averages were calculated at 11 different frequencies (250-8000 Hz) of the auditory airway, and statistical analysis was performed. The average hearing thresholds were > 20 dB, with standard audiometry at 6000-8000 Hz, and < 20 dB at all other frequencies. After treatment, the average auditory threshold decreased to < 20 dB at 6000-8000 Hz (p < 0.0001). Pure-tone hearing thresholds were improved at all frequencies after treatment, with statistically significant differences at all frequencies except 12,000, 14,000 and 16 000 Hz (p < 0.05). There was no permanent hearing loss caused by acute brucellosis, and hearing thresholds were restored after treatment. It was concluded that acute brucellosis affects the auditory system, especially at high frequencies, and that patients with all forms of brucellosis should be evaluated for hearing loss.     

Application of Rhenium-186 Radiosynovectomy in Elbow Diffuse Pigmented Villonodular Synovitis. - A Case Report with Multiple Joint Involvement

After surgical therapy of diffuse pigmented villonodular synovitis (DPVNS), recurrence is seen in almost half of the patients. The effectiveness of radiosynovectomy (RSV) in preventing recurrence and complaints of DPVNS is well known. Elbow involvement in DPVNS is a very rare condition; therefore, RSV in elbow hasn’t been experienced widely. The aim of this case report is to show the effectiveness of RSV with rhenium-186 (Re-186) sulfide colloid. We applied Re-186 sulfide colloid to the elbow joint of DPVNS patients six weeks after arthroscopic synovectomy. As a result, the patient did not have any complaints, and our findings are compatible with residue or recurrence on magnetic resonance imaging (MRI) in sixth and twentieth month controls after administration. We concluded that Re-186 is an effective adjuvant therapy for the prevention of recurrence and complaints.     

Povidone iodine in the treatment of adenoviral conjunctivitis in infants

Context: Adenoviral conjunctivitis.

Objective: To examine the effects of conjunctival irrigation with povidone iodine in infants with adenoviral conjunctivitis.

Material and methods: An outbreak of adenovirus conjunctivitis occurred between September and December 2012 at the neonatal intensive care unit of our hospital. Forty-three infants with adenoviral conjunctivitis were examined in this study. Thirty-five eyes of 35 infants who had detailed ophthalmological examination and clinical scoring were included. The conjunctiva of 15 infants (Group 1) were irrigated with povidone iodine 2.5% solution and then treated with preservative-free artificial tears and preservative-free antibiotic drops. Twenty infants (Group 2) were treated only with the same drops with the same posology, without conjunctival irrigation with povidone iodine. Patients were examined two times a week until the complete recovery. Lid edema, conjunctival chemosis, fragility of conjunctival vasculature, pseudomembrane formation, and corneal involvement were scored clinically.

Results: Twenty patients (57%) were female and 15 patients (43%) were male and mean age was 3.1 months (ranged from 1 to 4 months). No relation was found between gender and clinical scores. Statistically significant lower clinical scores were obtained from Group 1. The median recovery time was earlier in Group 1 (7?d) than Group 2 (12?d) (p?=?0.001).

Conclusion: Conjunctival irrigation with 2.5% povidone iodine is effective in the treatment of adenoviral conjunctivitis in infants.

Seroprevalence of tetanus immunity among noninsulin-dependent diabetes mellitus patients

Tetanus is a preventable disease that continues to affect people in both developing and developed countries. The aim of the present study was to evaluate the immunity profile to tetanus in patients with Type II diabetes mellitus (DM) and to compare them with healthy controls. The tetanus antitoxin levels in 310 diabetic patients (104 males and 206 females) and in 200 healthy controls (72 males and 128 females) were measured by ELISA (Virotech, Germany). The mean antitoxin concentration in patient and control groups were 0.8238+/-1.61 and 0.9978+/-1.49 IU/ml, respectively. There was a statistically significant difference between the two groups (z=-3.520, P=.0001 and odds ratio was 2.367). There was a definitive inverse correlation between the duration of diabetes and tetanus antibody titers (Spearman's correlation analysis, r=-.155, P=.006). A gender-dependent difference in the susceptibility to tetanus was present in the diabetic group with antibody titers being significantly higher in males compared with females (z=-2.267, P=.023). For both of control (chi(2)=20.207, P=.003) and patient (chi(2)=43.532, P=.0001) groups, there was a significant inverse correlation between the tetanus immunity levels and age. Statistically, a significant drop in antibody titers of both groups was found as the period past from the last immunization increased (Pearson correlation analysis: for patient group r=-.364, P=.0001; for control group r=-.143, P=.044). The tetanus antitoxin levels were significantly increased in individuals who had primary immunization during childhood (for patient group chi(2)=17.191, P=.0001; for control group chi(2)=9.911, P=.007). A significant reduction in the level of antitoxin immunity to tetanus in association with an increased susceptibility to infections in patients with diabetes may implicate the need for improving vaccination rates in this patient group.     

Two level pedicle substraction osteotomies for the treatment of severe fixed sagittal plane deformity: computer software-assisted preoperative planning and assessing

Purpose

To evaluate the efficacy of two level pedicle substraction osteotomies (PSOs) planned preoperatively with a computer software, in the patients with severe fixed sagittal plane deformities.

Methods

In the literature, there are studies indicating that two level PSOs may be required in severe cases. However, the results of two level PSOs preoperatively planned with computer software-assistance have not yet been reported in the English literature. Severe fixed sagittal plane deformities of 11 patients are described. Preoperative surgical planning was done with the aid of a computer software. Two level PSOs were indicated after the process. After the application of the indicated surgical technique, clinical and radiological results were evaluated in the preoperative, the early postoperative periods and during the last follow-up.

Results

The mean sagittal vertical axis was found as 190.5 (range 161–220) mm in the preoperative period, 23.5 (range ?27 to 61) mm in the early postoperative period (P < 0.001) (87.7 % correction) and 34.5 (range ?3 to 55) mm during the last follow-up (P < 0.001). The mean pelvic tilt (PT) significantly decreased from 38.3° (range 21°–63°) preoperatively to 23.8° (range 18°–42°) postoperatively (P = 0.008) and to 27.5° (range 17°–42°) during the last follow-up (P = 0.042). The mean lumbar lordosis (LL) was 2.8° (range ?29° to 20°) preoperatively, ?35.6° (range ?54° to 23°) early postoperatively (P < 0.001) and ?33.6° (range ?52° to 20°) during the last follow-up (P < 0.001). The average amount of bleeding was 5345 (range 2600–7415) ml.

Conclusion

Although a statistically significant correction was obtained, the mean PT and PI–LL value could not be restored in physiological limits during the last follow-up. Thus, two level PSOs performed after computer software (surgimap) assisted preoperative planning failed to correct severe fixed sagittal plane deformities. Besides, this procedure is of possible risks for major complications such as a result of excessive bleeding. We recommend that two level PSOs should be rarely indicated, but preferred as an alternative technique only in the most severe cases.

     

Endocarditis caused by Stenotrophomonas maltophilia

Stenotrophomonas maltophilia is frequently isolated from hospital environments. In recent years, it has been reported that this bacterium is causing hospital infections at increasing rates and is gaining importance because of its multiple resistance. Although it has been related to several infections, endocarditis caused by S. maltophilia is rarely encountered. In this case study, endocarditis in a 40-y-old man with a history of aortic valve replacement is presented. Blood cultures revealed S. maltophilia to be the aetiological agent, which showed multiresistance to various antibiotics. Ticarcillin-clavulanate and trimethoprim-sulfamethoxazole were used in the treatment.     

Antioxidant effects of vitamin D on lacrimal glands against high dose radioiodine-associated damage in an animal model

Purpose: To evaluate antioxidant effects of active vitamin D (calcitriol) against high-dose radioiodine (RAI) therapy-associated damage of lacrimal gland.

Materials and methods: Wistar albino rats were used and divided into three groups randomly (n?=?12/group). The first group was appointed as the negative control group and received no RAI or medication. The second group was appointed as the positive control group that only received 3?mCi/kg (111 MBq/kg) RAI via gastric gavage and the last group was the treatment group that received 3?mCi/kg RAI via same method and calcitriol (200?ng/kg/day) via intraperitoneal administration. Seven days after RAI administration, bilateral intraorbital (IG), extraorbital (EG) and Harderian (HG) glands were removed for the evaluations of histopathologic, tissue cytokine, total oxidant status (TOS) and total antioxidant status (TAS).

Results: RAI led to significant increase in tissue TOS, TNF-α, IL-6 levels and significant decrease in IL-10 and TAS levels (p?p?p?p?=?0.049), periductal fibrosis in EG and HG (p?=?0.049 and 0.038, respectively), abnormal cell outlines in EG and HG (p?=?0.020 and 0.011, respectively) and variation in cell size in the IG and the HG (p?=?0.003 and 0.049 respectively).

Conclusions: RAI caused significant oxidative stress and inflammation in lacrimal glands. Vitamin D demonstrated potent anti-inflammatory, antioxidant and radio-protective effects on lacrimal glands in histopathologic, tissue cytokine and oxidant/antioxidant level evaluations.
