RESUMEN

Diabetes is a metabolic disorder associated with various complications, including periodontitis. The risk of periodontitis is increased in patients with diabetes, while vitamin D deficiency is associated with both diabetes and periodontitis. Thus, there is a need to identify the molecular effects of vitamin D on the regulation of inflammation and glucose in diabetes-associated periodontitis. The Web of Science, Scopus, and PubMed databases were searched for studies of the molecular effects of vitamin D. Molecular effects were reportedly mediated by salivary secretions, interactions of advanced glycation end products (AGEs) with receptors of AGEs (RAGEs), cytokines, and oxidative stress pathways linking diabetes with periodontitis. Vitamin D supplementation attenuates inflammation in diabetes-associated periodontitis by reducing the levels of inflammatory cytokines and numbers of immune cells; it also has antibacterial effects. Vitamin D reduces cytokine levels through regulation of the extracellular signal-related kinase 1/2 and Toll-like receptor 1/2 pathways, along with the suppression of interleukin expression. Glucose homeostasis is altered in diabetes either because of reduced insulin production or decreased insulin sensitivity. These vitamin D-related alterations of glucoregulatory factors may contribute to hyperglycaemia; hyperglycaemia may also lead to alterations of glucoregulatory factors. This review discusses the pathways involved in glucose regulation and effects of vitamin D supplementation on glucose regulation. Further studies are needed to characterise the effects of vitamin D on diabetes-associated periodontitis.

RESUMEN

The commitment of the existent study was to develop a mucoadhesive in situ gel systems of vitamin B12 for the management of dry eye disease. The gels were prepared using pluronic F-127 and either of chitosan, carbapol 971P, sodium alginate, or hydroxy propyl methyl cellulose. Drug-excipients compatibility was investigated by means of differential scanning calorimetry and Fourier transform infrared spectroscopy. The gels were characterized for pH, clarity, gelling capacity, viscosity, and adhesion. In vitro release of vitamin B12 from the selected gels was investigated. In vivo effectiveness of the selected gel was determined in rabbit models using Schirmer's and fluorescein tests. The compatibility studies revealed the possibility of incidence of drug/polymer interaction in some formulations. F2-containing pluronic F127 and hydroxypropyl methyl cellulose showed the most appropriate physical characterization and in vitro release profile. The prepared gels showed prolonged drug release with drug release mechanism of combined diffusion and erosion. The in vivo study revealed good effectiveness of the prepared mucoadhesive in situ gel system of vitamin B12 in the treatment of dry eye disease that was comparable to that of the marketed drops.

RESUMEN

The Milwaukee County Zoo has housed common vampire bats (Desmodus rotundus) since 1973. The bats are fed defibrinated cow's blood supplemented with a liquid pediatric multivitamin. From July 2013 to May 2014, multiple deaths occurred in colony bats, including five juveniles with multiple bone fractures and failure of endochondral ossification, three adults with cerebellar necrosis, and one adult with subcutaneous hemorrhage. In November 2013, an adult bat developed a nonhealing left wing hematoma and eventually succumbed 9 mo later. A postmortem examination revealed multifocal extensive necrohemorrhagic and suppurative ulcerative dermatitis with no underlying cause determined. From July to December 2014, five of nine adult bats in the colony developed similar hematomas along with gingival bleeding. One euthanized bat had a serum ascorbic acid level of 0.08 mg/dl and marked generalized subcutaneous hemorrhage. A therapeutic trial was initiated in which two bats received defibrinated cow's blood supplemented only with oral vitamin C, 100 mg/kg PO q24h for 3 d, and then 50 mg/kg PO q24h. Two other bats received nonsupplemented defibrinated cow's blood and were given vitamin K 3.3 mg/kg SC q12h for 3 d, and then 3.3 mg/kg SC q24h for 7 d. The bats supplemented with vitamin C improved, supporting a diagnosis of vitamin C deficiency. All bats were subsequently supplemented with vitamin C leading to resolution of all lesions within 10 d to 2 mo. Vitamin C is necessary for collagen synthesis, which is required for proper wound healing, capillary and cartilage strength, osteoid production, and pial membrane formation of the cerebellum. Several bat species cannot synthesize vitamin C and require a dietary source. This is the first report of vitamin C deficiency in a colony of vampire bats leading to severe chronic subcutaneous hemorrhage, bone fragility, microfractures, cerebellar necrosis, and death.

RESUMEN

OBJECTIVES: Vitamin D deficiency/insufficiency is a worldwide public health issue that has been linked to numerous inflammatory disorders, including periodontitis. There is increasing support for a role for adequate vitamin D levels in overall health. Populations with darker skin color have a higher prevalence of vitamin D deficiency/insufficiency and periodontitis. The purpose of this small pilot study was to investigate the influence of 12 weeks of 25(OH)D vitamin D supplementation (VDS) on mediators of systemic inflammation in dark-skinned, periodontitis patients. MATERIALS AND METHODS: A total of 23 patients with moderate to severe periodontitis were randomly assigned to the vitamin D group or placebo group and received intensive single visit scaling and root planning to elicit a systemic inflammatory response. RESULTS: Vitamin D supplementation increased serum 25(OH)D levels approximately 2-fold over baseline levels; moreover, VDS group had reduced peripheral blood CD3 and CD3+CD8+ cytotoxic T lymphocyte (CTLs) counts and reduced pro-inflammatory salivary cytokines. In contrast, VDS group had higher levels of the autophagy-related proteins and other proteins crucial for anti-microbial autophagy in whole blood PBMCs. CONCLUSION: In conclusion, VDS has multiple benefits for reducing systemic inflammation and promoting induction of autophagy-related proteins related to anti-microbial functions.

RESUMEN

Periodontitis is a complex chronic inflammatory noncommunicable disease, initiated by the development of a dysbiotic microbial plaque biofilm below the gingival margin. Whilst the pathogenic biofilm is a "necessary cause" of periodontitis, it is insufficient on its own to cause the disease, and a destructive immune-inflammatory response is a key to the translation of risk to destructive events. Other exposures or "component causes" include individual genetic predisposition, lifestyle (including smoking and nutrition), and environmental factors. Dietary nutrients are essential for life as they provide crucial energy sources in the form of macronutrients, as well as important cofactors in the form of micronutrients, which regulate the functionality of enzymes during the regulation of anabolic and catabolic processes in human cells. Moreover, micronutrients can regulate gene transcription factors, such as the proinflammatory nuclear factor kappa B and the anti-inflammatory nuclear factor (erythroid-derived 2)-like 2. This review focuses on the role of vitamins (vitamin A, carotenoids, the vitamin B complex, vitamins C, D, and E, and coenzyme Q10) and minerals (calcium, magnesium, iron, zinc, potassium, copper, manganese, and selenium) in human physiology and the impact of their deficiencies upon periodontal health and disease.

RESUMEN

BACKGROUND: Antipsychotic (neuroleptic) medication is used extensively to treat people with chronic mental illnesses. Its use, however, is associated with adverse effects, including movement disorders such as tardive dyskinesia (TD) - a problem often seen as repetitive involuntary movements around the mouth and face. Vitamin E has been proposed as a treatment to prevent or decrease TD. OBJECTIVES: The primary objective was to determine the clinical effects of vitamin E in people with schizophrenia or other chronic mental illness who had developed antipsychotic-induced TD.The secondary objectives were:1. to examine whether the effect of vitamin E was maintained as duration of follow-up increased;2. to test the hypothesis that the use of vitamin E is most effective for those with early onset TD (less than five years) SEARCH METHODS: We searched the Cochrane Schizophrenia Group Trials Register (July 2015 and April 2017), inspected references of all identified studies for further trials and contacted authors of trials for additional information. SELECTION CRITERIA: We included reports if they were controlled trials dealing with people with antipsychotic-induced TD and schizophrenia who remained on their antipsychotic medication and had been randomly allocated to either vitamin E or to a placebo, no intervention, or any other intervention. DATA COLLECTION AND ANALYSIS: We independently extracted data from these trials and we estimated risk ratios (RR) or mean differences (MD), with 95% confidence intervals (CI). We assumed that people who left early had no improvement. We assessed risk of bias and created a 'Summary of findings' table using GRADE. MAIN RESULTS: The review now includes 13 poorly reported randomised trials (total 478 people), all participants were adults with chronic psychiatric disorders, mostly schizophrenia, and antipsychotic-induced TD. There was no clear difference between vitamin E and placebo for the outcome of TD: not improved to a clinically important extent (6 RCTs, N = 264, RR 0.95, 95% CI 0.89 to 1.01, low-quality evidence). However, people allocated to placebo may show more deterioration of their symptoms compared with those given vitamin E (5 RCTs, N = 85, RR 0.23, 95% CI 0.07 to 0.76, low-quality evidence). There was no evidence of a difference in the incidence of any adverse effects (9 RCTs, N = 205, RR 1.21, 95% CI 0.35 to 4.15, very low-quality evidence), extrapyramidal adverse effects (1 RCT, N = 104, MD 1.10, 95% CI -1.02 to 3.22, very low-quality evidence), or acceptability of treatment (measured by participants leaving the study early) (medium term, 8 RCTs, N = 232, RR 1.07, 95% CI 0.64 to 1.80, very low-quality evidence). No trials reported on social confidence, social inclusion, social networks, or personalised quality of life, outcomes designated important to patients. There is no trial-based information regarding the effect of vitamin E for those with early onset of TD. AUTHORS' CONCLUSIONS: Small trials of limited quality suggest that vitamin E may protect against deterioration of TD. There is no evidence that vitamin E improves symptoms of this problematic and disfiguring condition once established. New and better trials are indicated in this under-researched area, and, of the many adjunctive treatments that have been given for TD, vitamin E would be a good choice for further evaluation.

RESUMEN

Periodontal disease, a relevant public health problem worldwide, is generally considered a common pathology of elderly people. In this respect, there is agreement about that nutritional status may be a modifying factor in the progression and healing of the periodontal tissues. Vitamins have been recommended as nutraceuticals for prevention and treatment of some pathological conditions, such as cardiovascular diseases, obesity or cancer. Thus, a systematic approach to determining how the different vitamin type could ameliorate periodontal risks or improve periodontal health is necessary to further the understanding of the potential benefits and risks of vitamins supplementation use. For this, a systematic review of English-written literature in PubMed until February 2018, which included both human and animal research on the relationship of each vitamin with periodontal disease, was conducted. Among all the analyzed vitamins those with antioxidant capacity and effects on immune system seem to be useful for prevention or improvement of periodontal disease, as well as those implicated in bone metabolism. In the first case, there are quite information in favor of various vitamins, mainly vitamin C, that is the most studied. In the second case, vitamin D seems to have the most relevant role.

RESUMEN

BACKGROUND: Oscarvit (OSC) is an in-house preparation consisting of calcium, magnesium, phosphorus, strontium, Vitamin D, and eggshell membrane hydrolysate containing naturally occurring glycosaminoglycans and sulfated glycoproteins. OSC has been used both in an open-label human study and in vitro in osteoblasts. METHODS: Fifteen patients divided into three groups received oral OSC 0.6 g three times daily for 20 days. The main outcome measures were regional skeletal pain over the treatment period. For the in vitro experiments eight primary human osteoblasts cultures were established from trabecular bone, six of them from the femoral head, and two from the tibia. Cells were cultured for five to 20 days in the presence of 20 µg/ml OSC. Immunocytochemistry and RT-PCR were used to detect molecular alterations involved in the mineralization process. Calcium concentration was measured by means of a colorimetric assay and cell viability was analyzed using the LDH cytotoxicity assay. To investigate whether the osteoblasts response to OSC is associated with signaling processes the ERK1/2 and AKT signal transduction pathways were analyzed. RESULTS: Open label human study: OSC, 0.6 g three times daily, resulted in a significant positive effect on pain alleviation of 42% after 5 days (p < 0.001), 57% after 10 days and 68% after 20 days (p < 0.0001; for both time points), with no side-effects being reported. In vitro analysis: In osteoblasts, growing in OSC-supplemented media significant overexpression of bone γ-carboxylglutamic acid-containing protein, secreted phosphoprotein-1, integrin binding sialoprotein, and dentin matrix phosphoprotein genes could be detected when compared to control osteoblasts grown in the absence of OSC. Moreover, OSC-treated osteoblasts produced over the study period vast extracellular calcium deposits without any loss of cellular integrity or signs of cellular toxicity. In addition OSC promotes osteoblast differentiation and activates the AKT signaling pathway. CONCLUSION: This open label study provides preliminary evidence of the efficacy of OSC. Despite the limitations (small heterogeneous patient group) the findings can be viewed as a necessary investigation that supports further clinical trials with a double-blind controlled design. Experiments at cellular and molecular level provide supplementary information about OSC that increases mineralization in osteoblasts and activation of the AKT pathway. TRIAL REGISTRATION: DRKS00013233 , 06th November 2017, retrospectively registered.

RESUMEN

The aim of the study was to show whether there is any influence of food, drink or drug intake on the formation of tooth discoloration. A total of 500 patients aged 15-25 years were examined to take part in the study. Of these, 60 patients were selected and divided into two groups of 30 patients each. Group 1 included patients with black pigmentation on vestibular/oral tooth surfaces. Group 2 included patients without discoloration (control). Data were recorded in a questionnaire. Atomic absorption spectrometry was used to determine elements in discoloration samples. The Caries Risk Test (CRT) buffer was used to assess buffer capacity of saliva, while CRT bacteria were used to determine the presence of Streptococcus mutans and Lactobacillus spp. Statistically significant between-group differences were found for the intake of collard greens and beets (p<0.05), but not for other vegetables. As for drink consumption, patients with pigmentation reported less wine intake (p<0.05) than those without pigmentation. There was no difference according to drug intake between patients with and without pigmentation. Patients with pigmentation were older, smoked and had lower saliva pH with lower presence of Streptococcus mutans than those without pigmentation (p<0.05). In tooth discoloration samples, there were traces of calcium, magnesium, iron, copper and zinc. The appearance of tooth discoloration is influenced by many factors, among which diet and saliva seem to be very important. Our study showed that patients with black pigmentation used to take more beets, while patients without pigmentation were taking more collard greens and red wine.

RESUMEN

BACKGROUND: Burning mouth syndrome (BMS) is a term used for oral mucosal pain (burning pain or discomfort in the tongue, lips or entire oral cavity) without identifiable cause. General population prevalence varies from 0.1% to 3.9%. Many BMS patients indicate anxiety, depression, personality disorders and impaired quality of life (QoL). This review updates the previous versions published in 2000 and 2005. OBJECTIVES: To determine the effectiveness and safety of any intervention versus placebo for symptom relief and changes in QoL, taste, and feeling of dryness in people with BMS. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 31 December 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 11) in the Cochrane Library (searched 31 December 2015), MEDLINE Ovid (1946 to 31 December 2015), and Embase Ovid (1980 to 31 December 2015). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. We placed no restrictions on the language or date of publication when searching the electronic databases SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any treatment against placebo in people with BMS. The primary outcomes were symptom relief (pain/burning) and change in QoL. Secondary outcomes included change in taste, feeling of dryness, and adverse effects. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Outcome data were analysed as short-term (up to three months) or long-term (three to six months). MAIN RESULTS: We included 23 RCTs (1121 analysed participants; 83% female). Interventions were categorised as: antidepressants and antipsychotics, anticonvulsants, benzodiazepines, cholinergics, dietary supplements, electromagnetic radiation, physical barriers, psychological therapies, and topical treatments.Only one RCT was assessed at low risk of bias overall, four RCTs' risk of bias was unclear, and 18 studies were at high risk of bias. Overall quality of the evidence for effectiveness was very low for all interventions and all outcomes.Twenty-one RCTs assessed short-term symptom relief. There is very low-quality evidence of benefit from electromagnetic radiation (one RCT, 58 participants), topical benzodiazepines (two RCTs, 111 participants), physical barriers (one RCT, 50 participants), and anticonvulsants (one RCT, 100 participants). We found insufficient/contradictory evidence regarding the effectiveness of antidepressants, cholinergics, systemic benzodiazepines, dietary supplements or topical treatments. No RCT assessing psychological therapies evaluated short-term symptom relief.Four studies assessed long-term symptom relief. There is very low-quality evidence of a benefit from psychological therapies (one RCT, 30 participants), capsaicin oral rinse (topical treatment) (one RCT, 18 participants), and topical benzodiazepines (one RCT, 66 participants). We found no evidence of a difference for dietary supplements or lactoperoxidase oral rinse. No studies assessing antidepressants, anticonvulsants, cholinergics, electromagnetic radiation or physical barriers evaluated long-term symptom relief.Short-term change in QoL was assessed by seven studies (none long-term).The quality of evidence was very low. A benefit was found for electromagnetic radiation (one RCT, 58 participants), however findings were inconclusive for antidepressants, benzodiazepines, dietary supplements and physical barriers.Secondary outcomes (change in taste and feeling of dryness) were only assessed short-term, and the findings for both were also inconclusive.With regard to adverse effects, there is very low-quality evidence that antidepressants increase dizziness and drowsiness (one RCT, 37 participants), and that alpha lipoic acid increased headache (two RCTs, 118 participants) and gastrointestinal complaints (3 RCTs, 138 participants). We found insufficient/contradictory evidence regarding adverse events for anticonvulsants or benzodiazepines. Adverse events were poorly reported or unreported for cholinergics, electromagnetic radiation, and psychological therapies. No adverse events occurred from physical barriers or topical therapy use. AUTHORS' CONCLUSIONS: Given BMS' potentially disabling nature, the need to identify effective modes of treatment for sufferers is vital. Due to the limited number of clinical trials at low risk of bias, there is insufficient evidence to support or refute the use of any interventions in managing BMS. Further clinical trials, with improved methodology and standardised outcome sets are required in order to establish which treatments are effective. Future studies are encouraged to assess the role of treatments used in other neuropathic pain conditions and psychological therapies in the treatment of BMS.

RESUMEN

BACKGROUND: Restless legs syndrome (RLS) is defined as the spontaneous movement of the limbs (mainly legs) associated with unpleasant, sometimes painful sensation which is relieved by moving the affected limb. Prevalence of RLS among people on dialysis has been estimated between 6.6% and 80%. RLS symptoms contribute to impaired quality of life and people with RLS are shown to have increased cardiovascular morbidity and mortality.Various pharmacological and non-pharmacological interventions have been used to treat primary RLS. However, the evidence for use of these interventions in people with chronic kidney disease (CKD) is not well established. The agents used in the treatment of primary RLS may be limited by the side effects in people with CKD due to increased comorbidity and altered drug pharmacokinetics. OBJECTIVES: The aim of this review was to critically look at the benefits, efficacy and safety of various treatment options used in the treatment of RLS in people with CKD and those undergoing renal replacement therapy (RRT). We aimed to define different group characteristics based on CKD stage to assess the applicability of a particular intervention to an individual patient. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Specialised Register to 12 January 2016 through contact with the Information Specialist using search terms relevant to this review. SELECTION CRITERIA: Randomised controlled trials (RCT) and quasi-RCTs that assessed the efficacy of an intervention for RLS in adults with CKD were eligible for inclusion. Studies investigating idiopathic RLS or RLS secondary to other causes were excluded. DATA COLLECTION AND ANALYSIS: Two authors independently assessed studies for eligibility and conducted risk of bias evaluation. Results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) and 95% CI for continuous outcomes. MAIN RESULTS: We included nine studies enrolling 220 dialysis participants. Seven studies were deemed to have moderate to high risk of bias. All studies were small in size and had a short follow-up period (two to six months). Studies evaluated the effects of six different interventions against placebo or standard treatment. The interventions studied included aerobic resistance exercise, gabapentin, ropinirole, levodopa, iron dextran, and vitamins C and E (individually and in combination).Aerobic resistance exercise showed a significant reduction in severity of RLS compared to no exercise (2 studies, 48 participants: MD -7.56, 95% CI -14.20 to -0.93; I2 = 65%), and when compared to exercise with no resistance (1 study, 24 participants: MD -11.10, 95% CI -17.11 to -5.09), however there was no significant reduction when compared to ropinirole (1 study, 22 participants): MD -0.55, 95% CI -6.41 to 5.31). There were no significant differences between aerobic resistance exercise and either no exercise or ropinirole in the physical or mental component summary scores (using the SF-36 form). Improvement in sleep quality varied. There was no significant difference in subjective sleep quality between exercise and no exercise; however one study reported a significant improvement with ropinirole compared to resistance exercise (MD 3.71, 95% CI 0.89 to 6.53). Using the Epworth Sleepiness Scale there were no significant differences between resistance exercise and no exercise, ropinirole, or exercise with no resistance. Two studies reported there were no adverse events and one study did not mention if there were any adverse events. In one study, one patient in each group dropped out but the reason for dropout was not reported. Two studies reported no adverse events and one study did not report adverse events.Gabapentin was associated with reduced RLS severity when compared to placebo or levodopa, and there was a significant improvement in sleep quality, latency and disturbance reported in one study when compared to levodopa. Three patients dropped out due to lethargy (2 patients), and drowsiness, syncope and fatigue (1 patient).Because of a short duration of action, rebound and augmentation were noted with levodopa treatment even though it conferred some benefit in reducing the symptoms of RLS. Reported adverse events were severe vomiting, agitation after caffeine intake, headaches, dry mouth, and gastrointestinal symptoms.One study (25 participants) reported iron dextran reduced the severity of RLS at weeks one and two, but not at week four. Vitamins C, E and C plus E (1 study, 60 participants) helped the symptoms of RLS with minimal side effects (nausea and dyspepsia) but more evidence is needed before any conclusions can be drawn. AUTHORS' CONCLUSIONS: Given the small size of the studies and short follow-up, it can only be concluded that pharmacological interventions and intra-dialytic exercise programs have uncertain effects on RLS in haemodialysis patients. There have been no studies performed in non-dialysis CKD, peritoneal dialysis patients, or kidney transplant recipients. Further studies are warranted before any conclusions can be drawn. Aerobic resistance exercise and ropinirole may be suitable interventions for further evaluation.

RESUMEN

IMPORTANCE: Scurvy remains prevalent in certain populations, including addicts, people of low socioeconomic status, and the severely malnourished. It classically presents as follicular hyperkeratosis and perifollicular hemorrhage of the lower extremities, as well as bleeding in other areas such as the gingiva and joints. This case presentation and literature review highlights the common pathophysiological findings associated with scurvy and current methods of diagnosis and treatment. OBSERVATION: The patient described in this case presented with sudden oligoarthritis and purpura of the lower extremities. Following progression of the patient's symptoms and a low vitamin C serum concentration, the patient was treated with vitamin C supplementation and dramatically improved. This was considered to be the result of an underlying vitamin C deficiency secondary to insufficient fruit and vegetable intake due to allergies. CONCLUSIONS AND RELEVANCE: This case highlights the importance of maintaining a high index of suspicion for scurvy in atypical presentations of purpura not better explained by another disease or in additional populations at high risk of vitamin C deficiency. Early diagnosis by either a primary care physician or dermatologist can expedite the treatment process and improve patient prognosis.

RESUMEN

The purpose of this study was to evaluate the clinical effect on the biochemical inflammatory markers of a single oral high dose of cholecalciferol in vitamin D-deficient patients undergoing the surgical removal of lower third molars.A randomized, split-mouth, single-blind study was conducted on 25 vitamin D-deficient patients ranging between 18 and 40 years of age requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina.All patients, with vitamin D3 blood levels ≦30 ng/mL, underwent bilateral surgical removal. The first extraction (control group) being conducted with the administration of a placebo, the second one (test group) being conducted with the preliminary administration of 300,000 IU of cholecalciferol 4 days before the procedure.At each surgery, clinical indexes, such as pain, edema and any functional limitation have been recorded. Clinical and biochemical parameters were registered 4 days before, immediately after, 3 and 7 days after the surgical procedure. The data obtained were processed using paired t-test. The clinical outcome parameters showed a slight to moderate improvement between the control and the vitamin-D treatment group, with statistical significance being obtained regarding the edema at defined time points. Interleukin-1-beta, interleukin-6, and tumor necrosis factor-alpha values were significantly lower (P < 0.01) for the test group after the surgery. The increase of vitamin D serum levels showed an impact on the outcome of the third molar surgery, eliciting a reduced inflammatory response and leading to a more favorable clinical course.

RESUMEN

PURPOSE: The aim was to systematically review the efficacy of vitamin D3 (VD3) supplementation on the osseointegration of implants. METHODS: The addressed focused question was "does VD3 supplementation affect osseointegration around implants?" Indexed databases were searched from 1969 up to and including March 2015 using various key words including: "Bone to implant contact"; "implant"; "vitamin D"; and "osseointegration." Letters to the editor, case reports/case series, reviews, and articles published in languages other than English were excluded. The pattern of the present systematic review was customized to primarily summarize the pertinent data. RESULTS: Six experimental studies (4 in rodents and 2 in rabbits) were included. Number of titanium implants placed ranged between 28 and 100 implants. Results from 5 studies showed that VD3 supplementation enhanced new bone formation and/or bone to implant contact (BIC) around implants. One study showed no significant difference in BIC and new bone formation around VD3 coated and noncoated implants. One study reported that insulin therapy with adjunct VD3 supplementation enhances new bone formation around implants in diabetic rats than when insulin replacement therapy is used alone. CONCLUSION: Efficacy of VD3 supplementation on osseointegration of implants remains controversial and requires further investigations.

RESUMEN

The identification of inflammatory periodontal disease and education in local and systemic risk factors and their management forms the foundation of the treatment of this disease. Nutrition is potentially a modifiable risk factor that could drive or abrogate the underlying oxidative stress in periodontitis. As research in this area is still in its infancy, clinical guidance on the delivery of dietary advice for susceptible patients is scarce. This paper will explain the possible mechanisms linking nutrition and periodontal disease, as well as the guidelines currently available to the dental profession. CPD/CLINICAL RELEVANCE: With a growing evidence base, an appreciation of the links between nutrition and inflammatory periodontal disease can help guide clinicians in educating patients on this potentially important modifiable risk factor.

RESUMEN

Vitamin D deficiency is associated with increased incidence of breast and colon cancer as well as with an unfavourable course of non-Hodgkin lymphoma. Vitamin D deficiency is common in cancer patients and is associated with poor cancer prognosis and disease progression. In breast cancer patients under polychemotherapy with anthracycline and taxane, a significant drop in 25(OH)D levels was observed. Osteo-malacia represents a new and previously unreported risk factor for the development of bisphosphonate-related osteonecrosis of the jaw. In vitamin D deficiency (until it is corrected) oral and parenteral bisphosphonates should not be used. Vitamin D status should be monitored in all cancer patients and treated by adequate vitamin D3 supplementation. This applies in particular to cancer patients with poor nutritional status, treatment with aromatase inhibitors, bisphosphonates, and CTX containing anthracycline, taxane and monoclonal antibodies as well as in cases of muscular or mucocutaneous disorders, fatigue and tumor cachexia.

RESUMEN

PURPOSE: To assess the anti-inflammatory effect of vitamin D on gingivitis at various doses. MATERIALS AND METHODS: In this randomized controlled trial, daily oral vitamin D supplementation was given in doses of 2000 IU for group A, 1000 IU for group B, 500 IU for group C and a placebo for group D over a 3-month period. The changes in gingival scores were measured after the 1st, 2nd and 3rd months. RESULTS: The gingivitis score changed in direct proportion to the dose of vitamin D supplementation. In group A, the mean gingival scores were 2.4 (baseline), 1.7 after the first month, 0.8 after the second month and 0.3 after the third month. The group B mean baseline gingival score of 2.3 decreased to 2.0 in the first month, 1.1 after the second month and 0.5 after the third month. In group C, the baseline gingival scores were 2.2 and 1.9 after one month, 1.4 after two months and 0.8 by the last visit. Comparing baseline gingivitis scores with the later-visit score using the Wilcoxon paired test, the significant anti-inflammatory effect was seen in group A after one month, in group B at two months and in group C at three months after oral vitamin D supplementation (P < 0.0001). However, group D did not show a significant antiinflammatory effect. CONCLUSION: There is a dose-dependent anti-inflammatory effect of vitamin D on gingivitis. Vitamin D is a safe and effective anti-inflammatory agent in doses ranging from 500 IU to 2000 IU. Results are apparent earlier with the higher dose of 2000 IU.

RESUMEN

Clinical rickets has not been reported previously in Embu district, Kenya. Baseline clinical assessments performed for a nutrition intervention study in preschool children (n=324) identified 28 cases of rickets (8.6% of study sample). Clinical characteristics included: delays of sitting, walking, and teething; bone and chest deformities; widened wrists and ankles; and bowed lower extremities. Risk factors identified were short duration of breastfeeding with feeding of cereal-based supplements with little or no milk, low calcium intake, limited sunlight exposure. Vitamin D and calcium deficiencies likely contributed to these cases. Treatment with Vitamin D3 and milk resulted in clinical improvement.
