Evaluation of Effects of the Human Immunodeficiency Virus on the Vestibular System by Using the Video Head Impulse Test.

OBJECTIVE: Some studies have suggested that the human immunodeficiency virus causes dizziness and other balance problems; however, the exact effects on the vestibular system in acute and chronic phases of the disease are not clear. In this study, we aimed to evaluate the effect of the human immunodeficiency virus on semicircular canals using a video head impulse test. MATERIALS AND METHODS: Seventy-two cases were included in the study. Twenty-six of the cases had positive human immunodeficiency virus RNA (group A) and 22 had negative human immunodeficiency virus RNA with positive anti-human immunodeficiency virus (group B) laboratory results. Twenty-four of the cases were healthy individuals (group C). The vestibular system was evaluated with a video head impulse test in all cases. RESULTS: In the evaluation of overt/covert saccades, a statistically significant difference was detected for the left posterior semicircular canal between group B and the other 2 groups. However, this was considered an incidental finding and not a clinically significant result. There was no other significant difference in the catch- up saccades for other canals. In addition, there was no statistically significant difference between the groups for the vestibulo-ocular reflex gain. CONCLUSION: Although the human immunodeficiency virus has been reported to be vestibulotoxic in previ- ous studies, we found that the video head impulse test findings were not affected in our patient groups. Because the video head impulse test is considered a high-frequency test of vestibulo-ocular reflex, it is pos- sible that vestibular effects of the human immunodeficiency virus can be confined to low frequencies. It is also possible that HIV affects the central structures while sparing the peripheral vestibular pathways.

Primary T-Cell Lymphoma of the Parotid Gland.

Primary malignant lymphomas of parotid gland are very rare. Most are B-cell lymphomas, and T-cell lymphomas are very rare. Unfortunately, fine needle aspiration biopsy is non-diagnostic. We, herein, present a case of a 51-year male, who presented with a large mass in the left parotid gland that had rapidly grown over a few months. As fine needle aspiration biopsy was non-diagnostic, we decided to take an incisional biopsy to disclose the pathology. The lesion was diagnosed as T-cell lymphoma after immunohistochemical examination of the specimens. Following 2-[18F] fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography (FDG-PET/CT), the disease was staged as 'Stage I'. The patient received six sessions of cyclophosphamide, doxorubicin, vincristine and prednisone protocol as chemotherapy management. After the completion of chemotherapy, complete remission was achieved. In suspected cases, an incisional open parotid core biopsy should be considered for a definite diagnosis. As the treatment of lymphomas is not surgical, this approach avoids a parotidectomy, which in turn, avoids facial nerve complications. Key Words: T-cell lymphoma, Parotid gland, Malignant lymphoma, Incisional biopsy, Fine needle aspiration biopsy.

Detection of human immunodeficiency virus (HIV) RNA in the sweat of HIV-infected patients.

OBJECTIVE: Human immunodeficiency virus (HIV) infection is a significant health problem. Many studies reported that HIV was mainly transmitted through parenteral exposure, sexual activity, and body secretions, such as saliva and semen. Many people, including health-care providers and patient relatives, may easily contact with the sweat of HIV-infected patients. Although reference books assert that HIV does not transmit through sweat, to our knowledge, there is no systemic study which this statement is based upon. This study aims to investigate the potential of sweat to transmit HIV infection. METHODS: This study included 31 treatment-naive HIV RNA-positive patients who were in the acute phase of the infection and 26 subjects with a negative HIV RNA test who had received antiviral treatment. A total of 57 sweat samples collected from intact skin areas were prospectively evaluated by polymerase chain reaction (PCR) for the presence of HIV RNA. HIV RNA levels in the blood samples were also noted. RESULTS: HIV RNA was not detected by PCR in any sweat sample taken from HIV-infected HIV RNA-negative and -positive subjects. CONCLUSION: The findings obtained in this study suggest that sweat by itself has no potential for transmitting HIV infection.

Comparing Spontaneous Closure and Paper Patching in Traumatic Tympanic Membrane Perforations.

The authors aim to analyze the effects of oral antibiotic treatment for traumatic tympanic membrane perforations and to compare the outcomes of patients with traumatic tympanic membrane perforation after paper-patching procedure and spontaneous healing.In this study, 80 patients with traumatic tympanic membrane perforation diagnosed in the otorhinolaryngology emergency department and outpatient clinic from March 2010 to January 2015 were retrospectively reviewed. If the patient is diagnosed at first week and the edge of perforation is moist with blood, our routine procedure is paper-patching (group 1). However, if the patients reject treatment or delay in admission, the authors follow up patients for spontaneous closure (group 2). Some of the patients got oral antibiotics for 7 days (amoxicillin/clavulanic acid, 1000 mg 2 times/d) while some others did not. Closure rates and effectivity of oral antibiotics were evaluated and compared between 2 groups.In total, 80 patients were analyzed. The closure rates of perforations were 95.2% for group 1 (n = 42) and 81.6% for group 2 (n = 38). Although the paper-patched patients (group 1) perforation closure rate (95.2%) is higher than the nontreated patients (group 2) closure rate (81.6%), it is not statistically significant (P > 0.05). Antibiotic administered 55 patients had a significantly higher closure rate (94.5%) than the 25 patients who are not treated with antibiotics (76%) (P = 0.023; P < 0.05).In patients with traumatic tympanic membrane perforations, spontaneous closure rate is quite high. This study showed us that antibiotherapy and paper-patch treatments increase the healing rates.

Eating disorders and food addiction in men with heroin use disorder: a controlled study.

PURPOSE: We aimed to determine the prevalence estimates of binge eating disorder, bulimia nervosa, anorexia nervosa, and food addiction in men with heroin use disorder and a matched sample of control participants. METHODS: A group of 100 men with heroin use disorder, consecutively admitted to a detoxification and therapy unit, were screened for DSM-5 eating disorders, along with a group of 100 male controls of similar age, education, and body mass index. The Yale Food Addiction Scale (YFAS), the Barratt Impulsivity Scale-version 11, and the Eating Attitudes Test were used for data collection. Patients were also evaluated for various aspects of heroin use disorder (e.g., craving) using the Addiction Profile Index. RESULTS: Binge eating disorder that met DSM-5 criteria was more prevalent in patients with heroin use disorder (21%) than in control subjects (8%) (odds ratio 3.1, 95% confidence interval 1.3-7.3; p < 0.01). Food addiction based on the YFAS was also more common among men with heroin use disorder (28%) than among control participants (12%) (odds ratio 2.9, 95% confidence interval 1.4-6.1; p < 0.01). A current food addiction was associated with more severe craving and having a history of suicide attempts in the patients. CONCLUSIONS: Co-occurring binge eating disorder and food addiction are highly frequent in men with heroin use disorder. Screening for binge eating disorder and food addiction in patients with substance use disorder is important, as interventions may improve treatment outcome in this patient group.

The relationship between second-to-fourth digit (2D:4D) ratios and problematic and pathological Internet use among Turkish university students.

Background and aims The ratio of the second and fourth fingers (2D:4D ratio) is a sexually dimorphic trait, with men tending to have lower values than women. This ratio has been related to prenatal testosterone concentrations and addictive behaviors including problematic video-gaming. We aimed to investigate the possible association between 2D:4D ratios and Internet addiction and whether such a relationship would be independent of impulsivity. Methods A total of 652 university students (369 women, 283 men), aged 17-27 years, were enrolled in the study. Problematic and pathological Internet use (PPIU) was assessed using the Internet Addiction Test (IAT). The participants also completed the Barratt Impulsiveness Scale (version 11; BIS-11) and had their 2D:4D ratios measured. Results 2D:4D ratios were not significantly different in women with PPIU and in those with adaptive Internet use (AIU). Men with PPIU exhibited lower 2D:4D ratios on both hands when compared with those with AIU. Correlation analysis revealed that 2D:4D ratios on both hands were negatively correlated with IAT scores among men, but not among women. The multiple linear regression analysis revealed that age, duration of weekly Internet use, impulsiveness, and 2D:4D ratios on the right hand were independently associated with IAT scores among men, and impulsivity did not mediate the relationship between 2D:4D ratios and PPIU. Conclusions For men, 2D:4D ratios on the right hand were inversely correlated with Internet addiction severity even after controlling for individual differences in impulsivity. These findings suggest that high prenatal testosterone levels may contribute to the occurrence of PPIU among men.

Publication rates of otolaryngology theses from Turkey in peer-reviewed journals.

OBJECTIVES: This study aims to examine the publication or presentation rates of theses in scientific journals and scientific meetings in the field of otorhinolaryngology in Turkey. PATIENTS AND METHODS: We randomly surveyed 2,705 specialists in the field of otorhinolaryngology in Turkey as of April 2014. Of these, 245 were applied a questionnaire on the continuation of their academic education, qualifications of the institutions where they were graduated from and worked and the status of their theses in terms of whether their theses were converted into a scientific article or presentation. RESULTS: Overall, 47.8% of the participants were still continuing their academic education, while 52.2% were not. The rate of the presentation of the theses at a national meeting was 58.4% and at an international meeting was 10.6%. The rates of publication in a national and international journal were 26.1% and 36.3%, respectively. CONCLUSION: As the physical and economic opportunities for experimental researches have increased, students have been encouraged to conduct researches and supportive solutions for the publication of theses have been created.

Research on the Submission, Acceptance and Publication Times of Articles Submitted to International Otorhinolaryngology Journals.

OBJECTIVE: The aim of this study was to provide insight into the acceptance and publication times of articles submitted to international otolaryngology journals. MATERIAL AND METHODS: The study was carried out by examining the top 37 journal titles returned in an online search for otolaryngology journals published from 1999 to 2013 that have an international status based on their impact factor. RESULTS: In total, 9,765 publications were examined. When journals were compared based on journal impact factor, statistically significant differences (p<0.01) were found. Comparisons of the acceptance and publication times for both original research and case reports revealed that these times have become shorter over the years. DISCUSSION: Journals with higher impact factors likely have larger workloads in terms of articles, and consequently, their acceptance and publication times might be longer. An implication from this study finding that these periods have decreased over the years is that these processes can be expedited by more intensive use of the Internet and increases in journal capacity and number of issues published. CONCLUSION: The expedition of these processes over time might result from journals' ability to use technology more intensively or from increases in journal's capacity and number of issues published.
