Abstract
Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo and nystagmus in clinics. Vertigo has many causes and the recurrence of vertigo is unknown. Among a lot of factors, vitamin D deficiency is more important. This study was conducted to determine the effect of vitamin D supplementation on torsional nystagmus in BPPV patients. This study wants to show the deficiency of vitamin D leads to the recurrence of BPPV.
Methods: This case-control study was conducted from April 2017 to May 2018. All eligible patients with BPPV were presented to the Audiology clinic of Babol Rouhani hospital consecutively. Diagnosis of BPPV and the presence of nystagmus were confirmed and serum vitamin D was assessed. Dix-halpike maneuver and videonystagmography (VNG) for assessing nystagmus were done and for serologic assessment, ELISA was performed for analyzing the level of hydroxy 25 vitamin D.Vitamin D sufficient patients (more than 20 ng/ml) with BPPV were considered as the control group and vitamin D deficient patients (less than 20 ng/ml) were as the test group.
  In all the patients of two groups, torsional nystagmus (vertical, horizontal and oblique) were studied and compared.
Results: Twenty-seven patients in each group have completed the study. The mean age of the control group and test group was 48.2+4.8, 47.8+5.7 and 47.2+4.9 years respectively (P=0.91). Two groups were comparable regarding nystagmus severity. All patients had at least two attacks During the last six months. The mean of serum 25 OHD was 33.81 in the control group and 11.41 in the test group that was statistically significant (P=0.001 for all) and the severity of torsional nystagmus in three axes of horizontal, vertical and oblique in the control group was 4.98, 9.06, 5.40 respectively and 3.32, 8.86, 6.93 in the test group that was statistically significant as compared with the control group (P=0.001).
Conclusion: Findings of this study indicate a relationship between vitamin D deficiency and recurrence of nystagmus in BPPV patients

Abstract
Background: one of the growing diseases in the world that affects patient life quality is Inflammatory bowel disease (IBD), including ulcerative colitis (UC). Many environmental factors, including nutritional deficiencies, may influence the development of the disease. This study aims to evaluate the role of the level of vitamin D in UC recurrence.
Methods: We performed this cross-sectional study at Qom University of Medical Sciences from September 2017 to September 2018 on 50 patients with inactive UC, at least six months after diagnosis, in Shahid Beheshti Hospital in Qom. Patients entered the study sequentially from the target population after describing how to perform the plan and obtaining informed consent. Demographic information, including gender, age, medical history, diseases, and body mass index (BMI), were collected using a checklist. Patients were followed for six months for symptoms and the frequency of disease relapse. During the visits, in terms of adherence to treatment and case of recurrence, the number and severity of recurrence were examined, and the results were recorded in the checklist of each patient. At the end of this period, serum vitamin D level was measured. Data were collected by a checklist and analyzed by independent samples t-test, Chi-square, and variance analysis in SPSS version 18.
Results: Examining the correlation between vitamin D levels and demographic variables shows that low vitamin D levels are significantly associated with an increase in the frequency of recurrences. However, there was no significant relationship between disease duration, age, and body mass index. Among 50 patients, 23 (%46) were male, and 27 (%54) were female, with a mean age of 35.24±10.07 and a mean duration of disease for 15.14±6.67 months. The mean frequency of relapse was 1.34±1.89. The mean level of serum vitamin D was 22.30±13.45 ng/dl. It was significantly associated with the frequency of relapse with a P<0.001.
Conclusion: Vitamin D insufficiency is associated with an increased risk of recurrence in patients with ulcerative colitis.
