Background: Recurrent aphthous stomatitis is one of the most prevalent oral mucosa diseases and the etiology is unclear. As a potent anti-inflammatory and immunomodulating agent, vitamin D can significantly affect oral cavity homeostasis. However, to the best of our knowledge, no study has been conducted in pediatric population on the potential role of vitamin D in recurrent aphthous stomatitis to date. The aim of the present study is to determine the vitamin D status in recurrent aphthous stomatitis in children. Methods: This study is conducted retrospectively. Seventy-two patients with minor recurrent aphthous stomatitis and 70 age-matched healthy controls included in the study. 25-Hydroxyvitamin D levels were measured in all patients using enzyme immunoassay. Results: Serum vitamin D levels were 16.4 (8.6) ng/mL in patient group and 23.1 (11.5) ng/mL in healthy controls. There was a statistically significant difference between the groups in terms of serum vitamin D levels ( P = .002). There was no significant correlation between serum vitamin D levels and the severity of the recurrent aphthous stomatitis ( r = 0.54, P = .76). Conclusions: Our study showed a significant difference in vitamin D levels between patients with recurrent aphthous stomatitis and the healthy control group. We also found no correlation between vitamin D status and the severity of the disease.

Background: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. Methods: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus. The vitamin D status of patients was measured and correlated to age, sex, season, etiology, laterality, degree of disease, and nicotine abuse. Moreover, parathyroid hormone and serum calcium levels of patients were obtained to assess for severe vitamin D deficiency and secondary hyperparathyroidism. Between January 2015 and December 2017, 65 patients with a mean age of 38.9 years and a total of 68 lesions were identified. Results: In total, 75.4% of patients had low vitamin D levels with a mean overall 25(OH)D level of 24.2 ng/mL. Specifically, 35.4% of patients were vitamin D deficient; another 40% were vitamin D insufficient, and only 24.6% of patients presented with sufficient vitamin D levels. Statistical analysis showed no significant difference comparing vitamin D levels of patients with idiopathic OCD to patients with traumatic OCD. Conclusion: We could not find any significant differences in the vitamin D status of patients with OCD of the talus compared with patients with foot and ankle disorders in general. However, we found that vitamin D deficiency was frequent in patients presenting with traumatic and idiopathic OCD of the talus. We believe it might be beneficial to routinely assess and treat the vitamin D status of patients. Level of Evidence: Level III, retrospective comparative study.

Objective: The objective of this study is to investigate the association between Vitamin D level and psoriasis, in particular in our city of the long, hot, and sunny weather, in an attempt to add a clarification to this controversial subject. Methods: A case–control study included 120 patients with psoriasis and 38 patients with psoriatic arthritis (PsA); 89 (56.3%) patients were male. Psoriasis area and severity index (PASI) was calculated for all patients with psoriasis and disease activity score using 28 joints (DAS28) and erythrocyte sedimentation rate (DAS28) was measured for all patients with PsA. The control group comprised 164 age- and sex-matched participants (91 males and 73 females). Vitamin D serum level was performed for both patients and controls. Results: Vitamin D levels in both patients and controls were 17.4±7.7 and 28.3±5.6, respectively. The level of Vitamin D was lower in a patient with disease duration equal and more than 10 years than those with a disease duration <10 years. There is no significant difference in Vitamin D levels between the two patient subgroups. Lower Vitamin D levels were associated with high PASI and high DAS28 in psoriasis and PsA, respectively. Conclusion: Patients with psoriasis and PsA associated with low levels of serum Vitamin D. Vitamin D deficiency was found to be associated with long disease duration in both psoriasis and PsA. Patients with active disease have lower Vitamin D levels.

Abstract BackgroundDupuytren’s disease(DD) is a progressive fibroproliferative condition involving contractures of the fascia of the palm. Up to now, there are no relevant investigations on patients with DD in case of serum vitamin D deficiency. We hypothesized that transforming growth factor-β1 (TGF-β1) is increased in patients with DD in consequence of vitamin D deficiency, thereby leading to myofibroblast differentiation and subsequent progression of contractures. MethodsThe study’s aim was to analyze serum vitamin D levels and explore possible clinical and immunohistochemical correlates with vitamin D concentrations in a group of patients with DD. Vitamin D levels were measured in all DD patients and healthy controls. In the patient group, clinical characteristics were compared between vitamin D deficient and non-deficient subgroups. Diseased palmar fascia samples were obtained from 14 patients undergoing fasciectomy for DD. Correlations between vitamin D levels and vitamin D receptor(VDR), TGF-β1 expression levels in collected fascia samples were evaluated. ResultsVitamin D concentrations were significantly lower in patients than healthy controls. In addition, total extension deficit of involved fingers was higher in vitamin D deficient patients. Moreover, a positive correlation was found between vitamin D levels and expression of VDR in pathologic fascia in patients undergoing fasciectomy for contracture. Serum vitamin D levels were found to be low in DD patients. Expression of VDR was lower in the vitamin D deficient group.ConclusionsThe results suggest a potential link between vitamin D status and DD but causation is not yet established. The potential role of vitamin D and its interaction with VDR and the TGF-β1 signaling pathway in the pathogenesis of DD needs to be explored further.

Background: This study was done to evaluate the association of serum vitamin D level with GDM (n=30) and without GDM (n=30). The age and body mass index of the participants along with their gestational age, gravidity and parity were harmonized. The serum vitamin D levels and blood glucose were investigated. The results revealed that, normal pregnant women had significantly higher vitamin D level than their GDM counterparts.Methods: This case-control study was conducted on healthy pregnant women attending routine antenatal care at Bangabandhu Sheikh Mujib medical university from January 2019 to December 2019 recruited at third trimester of gestation. We measured maternal serum vitamin D status (25[OH]D) in third trimester of pregnancy. GDM was diagnosed according to the American diabetes association. guidelines. Vitamin D status was defined as, vitamin D sufficiency (≥30 or ≥75 nmol/L), insufficiency (20-30 and 50-75 nmol/L), were used to categories participants according to their 25[OH]D concentrations. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression.Results: The mean serum vitamin D level was lower in case group case 23.4 (17.4±35.1) compared to that in control group 29.7 (15.4±39.8) and the difference between the 2 groups was statistically significant (p≤0.001). Sufficient level of vitamin D was more in control group (66.7%) than that of case group (26.1%). Insufficient level of vitamin D was higher in case (73.3%) group than that of control (33.3%) group. These findings were significant (p=0.021). Respondents with insufficient level of vitamin D have 3.1 times more chance to develop GDM.Conclusions: Serum vitamin D level is reduced in pregnant women having GDM.

Abstract. Observational studies performed in homogeneous groups to objectively investigate the cause and effect relationship between vitamin D deficiency and sleep disorders are scarce. In this study, it was aimed to analyze the relationship between the severity of OSAS and vitamin-D levels among the participants whose features affecting serum vit-D levels were minimised. Serum 25-OH vitamin-D levels in 121 OSAS Male patients diagnosed by polysomnography without any systemic disease or vitamin-D supplement that may effect the vitamin-D metabolism were measured. The study was conducted in winter (latitude: 41°). Anthropometric measures and biochemical tests were also performed. The distribution of vitamin-D levels was determined as severe deficiency, deficiency, insufficiency and sufficiency. Apnea-hypopne index (AHI) < 5 was considered as a control group. Patients were categorized into four groups according to AHI as control, mild, moderate and severe. The groups were similar in terms of age, BMI, lipid profile, serum calcium, anthropometric measures and smoking. There was no significant difference in the distribution of vitamin-D levels between the patient and control groups and also within OSAS subgroups (p = 0.57, p = 0.86, respectively). Odds ratio to have OSAS in patients with vitamin-D deficiency was found as 0.745 (95 %CI: 0.33–1.7). Multinominal regression analysis showed no significant relationship between the OSAS severity and the extent of vitamin-D status. Correlation analysis showed no significant relationship between vitamin-D and AHI (r = 0.017, p = 0.877). Vitamin-D status does not alter the severity of OSAS. Vitamin-D deficiency might be the result of lifestyle changes due to OSAS rather than a cause.

Objective: To compare the levels of 25-hydroxyvitamin D in patients with AIS and a control group. Methods: The patients were recruited from the outpatient clinic of our institution during the year of 2013. Children diagnosed with scoliosis before 10 or after 18 years of age, and those suffering from neurological or muscular disorders, congenital malformations or genetic syndromes were excluded. The 25-OHD levels were determined by a fully automated electrochemiluminescence test. The appropriate level of 25-OHD was defined as greater than 30 ng/mL. The results were compared to a group of healthy individuals. Results: In group 1 (control) 63,3% showed abnormal vitamin D levels, while 91% of patients with AIS presented a low level of vitamin D. The mean BMI was 19.6 kg/m2 for controls and 20.3 kg/m2 for group 2. Statistical analysis showed significant difference (p&lt;0.0001) between the levels of vitamin D. The average and minimum levels of vitamin D were respectively 27 and 13.6 ng/mL for group 1 and 18.8 and 3.13 ng/mL for AIS group. Conclusions: Patients with AIS had statistically significant lower levels of 25-OHD than healthy patients. Further research should be conducted to investigate the actual impact of serum vitamin D levels on the pathophysiology of AIS.

Candida-associated denture stomatitis (CADS) is a fungal infection affecting 60–65% of denture wearers. Its etiology is complex and multifactorial and often associated with host immunodeficiency. Evidence exists that vitamin D has potential immunomodulatory and anti-inflammatory effects. The aim of this case–control study was to assess the association between vitamin D levels and CADS. The study included 32 complete denture wearers with CADS and 32 sex- and age-matched complete denture wearers without CADS. The patients were clinically examined, and the severity of denture stomatitis was assessed according to Newton’s classification scale. The serum vitamin D level was determined via the use of an electrochemiluminescence assay. The vitamin D level in the CADS group and control group was 54.68 ± 17.07 and 56.82 ± 17.75 nmol/L, respectively. There was no significant difference between the groups (p = 0.622). Univariate logistic regression analysis showed that the presence of CADS was not associated with hypovitaminosis D (odds ratio (OR) = 1.44; 95% confidence interval (CI) = 0.37–5.54). It can be concluded that vitamin D is not associated with CADS and does not play a significant role in host susceptibility to CADS. This finding suggests that vitamin D screening is not indicated routinely in patients with Candida-associated denture stomatitis.

Objective: This study aimed to evaluate the association between serum vitamin D levels and benign paroxysmal positional vertigo (BPPV). Participants and Methods: This prospective study consisted of 137 participants. There were 69 participants in the BPPV group compared with 68 healthy participants. Blood samples from both groups were collected from all participants to assess serum vitamin D levels. Results: No significant difference in demographic data between BPPV and control groups. The results showed that the mean serum vitamin D levels in the BPPV group was lower than that of the control group ( P value = .001). Among BPPV participants, there was no statistically significant difference between mean serum vitamin D levels of participants with recurrent BPPV, and that of newly diagnosed BPPV participants ( P value = .313). Conclusion: A statistically significant association between lower mean serum vitamin D levels in the BPPV group compared with that of the control group. Therefore, low serum vitamin D levels may be one of the risk factors for BPPV.

Objective: To investigate whether serum vitamin D levels have an effect on pseudoexfoliation (PEX) glaucoma/syndrome development and on the control of glaucoma in these cases. </P><P> Method: A total of 31 cases with PEX glaucoma, 34 cases with the PEX syndrome and 43 control subjects of similar age and sex were included in the study. Vitamin D levels were compared between the groups and also between the cases where glaucoma surgery was performed or not. Results: PEX glaucoma group consisted of 17 males and 14 females, PEX syndrome group of 27 males and 7 females, and the control group of 27 males and 16 females. The mean age was 70.9±8.9 years, 72.1±7.3 years, and 67.9±9.1 years in PEX glaucoma, syndrome and control group, respectively. Mean vitamin D levels were 9.4±7.7 ng/mL, 7.9±6,1 ng/mL, 11.5±14.2 ng/mL in PEX glaucoma, syndrome and control group, respectively (p>0.05). The mean serum vitamin D level was 8.04±4.7 ng/mL in those who underwent glaucoma surgery and 10.1±8.7 ng/mL in those who didn't undergo glaucoma surgery in PEX glaucoma group (p>0.05). No difference was found between the PEX glaucoma subgroups in terms of the mean deviation when classified according to vitamin D levels (<10 ng/mL, ≥10 ng/mL) (p>0.05). Conclusion: Although we found no statistically significant difference between the PEX syndrome/ glaucoma, and control group in terms of serum vitamin D levels, serum vitamin D levels were lower in PEX syndrome and glaucoma group than control group. Our results indicate that serum vitamin D levels have no effect on the development of PEX glaucoma/syndrome or the control of the disorder in cases with PEX glaucoma. However, these results need to be supported with further studies on a larger number of patients and with longer follow-up.

Background: Alopecia areata is the commonest cause of non-scarring alopecia. Few previous studies have found correlation between AA and vitamin D deficiency, suggesting that vitamin D deficiency can be a risk factor for Alopecia areata. To compare serum vitamin D level between Alopecia areata patients and healthy controls; and to assess the relation between serum vitamin D levels and AA disease severity.Methods: This case control study included 30 newly diagnosed Alopecia areata patients. Thorough history was taken, detail examination was done and relevant findings were recorded in the standardized pro-forma. Their serum vitamin D (25-hydroxyvitamin D) levels were determined by competitive chemiluminescence methods; and were compared with that of age and sex matched healthy controls. Chi square test and Spearman’s rho correlation test were used for the inferential statistics using SPSS version 11.5. Results: There were 30 AA patients with mean age 28.37+10.07 years. Mean Severity of Alopecia Tool score was 3.56+3.50. Prevalence of 25-hydroxyvitamin D [25(OH)D] deficiency was significantly higher in AA group (83.3%) compared to the control group (53.3%) (P=0.01). Similarly, serum 25(OH)D level was reduced more in Alopecia areata group (12.84, IQR=8.87-20.47) than the control group (29.5, IQR=19.85-41.27) (P=0.06). There was inverse co-relation between serum 25(OH)D level and SALT score.Conclusions: Prevalence of serum 25(OH)D deficiency was significantly higher in Alopecia areata group compared to the control, with inverse co-relation between its level and Alopecia areata disease severity. Keywords: Alopecia areata; Nepal; SALT Score; Vitamin D.
