RESUMEN
AIM: A new implant system encompassing implants with a tri-oval cross-sectional design and a simplified site preparation protocol at low speed and no irrigation has been developed. The objective of this study was to assess the safety and efficacy of the new implant system using the minipig intraoral dental implant model. METHODS: Eight Yucatan minipigs were included. Twelve weeks after extractions, four implants per animal were randomly placed and allowed to heal transmucosal for 13 weeks: two Ø3.5 × 10 mm implants with a back-tapered collar and circular cross-section (control) and two Ø3.5 × 11 mm implants with tri-oval collar and cross-section (test). MicroCT and histological analysis was performed. RESULTS: Thirty-two implants were placed; one implant for the control group was lost. Histologically, BIC was higher in the test compared with the control group (74.1% vs. 60.9%, p < .001). At the platform level, inflammation was statistically significantly higher albeit mild in the test compared with the control group. No other significant differences were observed between groups. MicroCT analysis showed that bone-to-implant-contact (BIC) and trabecular thickness were statistically significantly higher for the test than the control group. Test group had significantly higher first BIC distance than controls on lingual sites. CONCLUSIONS: The present study results support the safety and efficacy of the new dental implant system and simplified site preparation protocol; human studies should be carried out to confirm these findings.

This study aimed to evaluate the effects of hesperidin (HE) on in vitro osteoclastogenesis and dietary supplementation on mouse periodontal disease and femoral bone phenotype. RAW 264.7 cells were stimulated with RANKL in the presence or absence of HE (1, 100 or 500 µM) for 5 days, and evaluated by TRAP, TUNEL and Western Blot (WB) analyses. In vivo, C57BL/6 mice were given HE via oral gavage (125, 250 and 500 mg/kg) for 4 weeks. A sterile silk ligature was placed between the first and second right maxillary molars for 10 days and microcomputed tomography (µCT), histopathological and immunohistochemical evaluation were performed. Femoral bones subjected or not to dietary HE (500 mg/kg) for 6 and 12 weeks were evaluated using µCT. In vitro, HE 500 µM reduced formation of RANKL-stimulated TRAP-positive(+) multinucleated cells (500 µM) as well as c-Fos and NFATc1 protein expression (p < 0.05), markers of osteoclasts. In vivo, dietary HE 500 mg/kg increased the alveolar bone resorption in ligated teeth (p < 0.05) and resulted in a significant increase in TRAP+ cells (p < 0.05). Gingival inflammatory infiltrate was greater in the HE 500 mg/kg group even in the absence of ligature. In femurs, HE 500 mg/kg protected trabecular and cortical bone mass at 6 weeks of treatment. In conclusion, HE impaired in vitro osteoclastogenesis, but on the contrary, oral administration of a high concentration of dietary HE increased osteoclast numbers and promoted inflammation-induced alveolar bone loss. However, HE at 500 mg/kg can promote a bone-sparing effect on skeletal bone under physiological conditions.

Congenital pericardial absence is a rare cardiac defect. Although most patients are asymptomatic, recognising this condition is clinically important as it can cause serious complications. We report the case of an asymptomatic 33-year-old woman seeking medical attention due to a family history of sudden cardiac death. The investigation led us to the diagnosis of congenital absence of the pericardium. The role of imaging in the diagnosis of this rare cardiac malformation is briefly discussed.

OBJECTIVE: This study was conducted to compare periodontal therapy outcomes during pregnancy and after delivery. MATERIALS AND METHODS: One hundred nine pregnant women up to the 20th gestational week (GW) were randomized into two groups: the test group (comprehensive periodontal therapy during pregnancy) and the control group (comprehensive periodontal therapy after delivery). Periodontal examinations comprised plaque index (PI), gingival index (GI), periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and gingival crevicular fluid (GCF) volume. After baseline examination, women in the test group received periodontal treatment up to the 24th GW. The final examination was performed at the 26th to the 28th GW. Women in the control group were treated 30 days after delivery and reexamined 30 days after treatment. RESULTS: Periodontal therapy significantly reduced periodontal inflammation in both groups. The mean percentage of sites with BOP was reduced from 49.14 % (±22.49) to 11.10 % (±7.84) and from 45.71 % (±17.86) to 8.07 % (±5.21) in the test and control groups, respectively (p = 0.95). No statistically significant differences were observed between groups concerning PI, GI, PPD, CAL, and GCF. The reduction in mean percentage of sites with BOP stratified for initial PPD ≥4 mm was higher in the control group (p < 0.01), but no differences were seen regarding GCF in these sites. CONCLUSIONS: Hormonal changes during pregnancy do not interfere in treatment outcomes in women with widespread gingival inflammation and limited periodontal destruction. The role of these hormonal changes in pregnant women with different disease patterns remains uncertain. CLINICAL RELEVANCE: Periodontal health can be reestablished irrespective of the hormonal challenge that takes place during pregnancy.

BACKGROUND: Periodontal disease has been linked to systemic diseases/disorders and a low-grade systemic inflammatory status originated from periodontitis has been proposed as a possible explanation for this association. This study evaluates the relationship, early in pregnancy, between gingival crevicular fluid (GCF) and serum levels of a panel of cytokines that have been implicated in PTB and periodontal disease. METHODS: One hundred pregnant women aged 18-35 years old with a gestational age up to 20 weeks were included (mean±SD gestational age:16.1±3.5 weeks). Four periodontal sites per subject were randomly selected for GCF collection. Serum and GCF levels of IL-1ß, IL-6, IL-8, IL-10, IL-12p70 and TNF-α were analyzed using a cytometric bead array. Regression and correlation analyses were used to assess the relationship between serum and GCF cytokine levels. RESULTS: Participants had widespread periodontal inflammation but limited periodontal destruction. Cytokine levels were significantly higher in GCF than serum for all cytokines but IL-10. GCF levels had small but significant effect on serum levels for IL-10 (ß=0.34±0.09, p<0.01), IL-12p70 (ß=0.48±0.08, p<0.01) and TNF-α (ß=0.29±0.09, p<0.01). Periodontal probing depth and bleeding on probing were significantly associated with GCF levels for IL-1ß, IL-6 and IL-8; however, they had negligible effect on serum cytokine levels. Correlation between GCF and serum levels was non-significant, except for IL-12p70, which showed a significant but small correlation between the two sources (r=0.32, p=0.001). CONCLUSIONS: GCF cytokine levels were not strongly associated with serum cytokine levels in pregnant women with widespread periodontal inflammation but limited periodontal destruction.

Myxomas are the most common type of benign cardiac tumor. The most frequent clinical presentations are symptoms resulting from atrioventricular valve obstruction or systemic embolization. Coronary embolization is a rare, although real and potentially fatal, complication of cardiac myxomas. We present a case report and review of the literature on this disease association. A 57-year-old woman was admitted to our coronary care unit with a diagnosis of non-ST elevation acute myocardial infarction. Transthoracic echocardiography showed a large left atrial mass attached to the interatrial septum, coral-like and with a friable appearance, suggestive of myxoma. Coronary angiography revealed no significant lesions and the patient underwent surgical excision of the mass, which histological study showed to be compatible with myxoma. The postoperative period was uneventful and the patient is doing well, with no recurrence of myxoma.

OBJECTIVES: The objective of this report was to provide a review of the minipig intraoral dental implant model including a meta-analysis to estimate osseointegration and crestal bone remodeling. METHODS: A systematic review including PubMed and EMBASE databases through June 2021 was conducted. Two independent examiners screened titles/abstracts and selected full-text articles. Studies evaluating titanium dental implant osseointegration in native alveolar bone were included. A quality assessment of reporting was performed. Random-effects meta-analyses and meta-regressions were produced for bone-implant contact (BIC), first BIC, and crestal bone level. RESULTS: 125 out of 249 full-text articles were reviewed, 55 original studies were included. Quality of reporting was generally low, omissions included animal characteristics, examiner masking/calibration, and sample size calculation. The typical minipig model protocol included surgical extraction of the mandibular premolars and first molar, 12±4 wks post-extraction healing, placement of three narrow regular length dental implants per jaw quadrant, submerged implant healing and 8 wks of osseointegration. Approximately 90% of studies reported undecalcified incandescent light microscopy histometrics. Overall, mean BIC was 59.88% (95%CI: 57.43-62.33). BIC increased significantly over time (p<0.001): 40.93 (95%CI: 34.95-46.90) at 2 wks, 58.37% (95%CI: 54.38-62.36) at 4 wks, and 66.33% (95%CI: 63.45-69.21) beyond 4 wks. Variability among studies was mainly explained by differences in observation interval post-extraction and post-implant placement, and implant surface. Heterogeneity was high for all studies (I2 > 90%, p<0.001). CONCLUSIONS: The minipig intraoral dental implant model appears to effectively demonstrate osseointegration and alveolar bone remodeling similar to that observed in humans and canine models.

INTRODUCTION: Proportionality of secondary mitral regurgitation (sMR) may be a key factor in deciding whether a patient may benefit from mitral intervention. The aim of this study was to evaluate the prognostic value of two different concepts of proportionality and assess their ability to improve MR stratification proposed by the American Society of Echocardiography (ASE) guidelines. METHODS: We conducted a retrospective analysis in patients with reduced left ventricular ejection fraction (LVEF) (<50%) and at least mild sMR. Proportionality status was calculated using formulas proposed by a) Grayburn et al. - disproportionate sMR defined as EROALVEDV >0.14; b) Lopes et al. - disproportionate sMR whenever measured EROA>theoretical EROA (determined as 50%×LVEF×LVEDVMitralVTI). Primary endpoint was all-cause mortality. RESULTS: A total of 572 patients (69±12 years; 76% male) were included. Mean LVEF was 33±9%, with a median left ventricular end-diastolic volume of 174 mL [136;220] and a median effective regurgitant orifice area of 14 mm2 [8;22]. During mean follow-up of 4.1±2.7 years, there were 254 deaths. There was considerable disagreement (p<0.001) between both formulas: of 96 patients with disproportionate sMR according to Lopes' criteria, 46 (48%) were considered proportionate according to Grayburn's; and of 62 patients with disproportionate sMR according to Grayburn's, 12 (19%) were considered proportionate according to Lopes' formula. In multivariate analysis, only Lopes' definition of disproportionate sMR maintained independent prognostic value (hazard ratio 1.5; 95% confidence interval 1.07-2.1, p=0.018) and improved the risk stratification of ASE sMR classification. CONCLUSION: Of the two formulas available to define disproportionate sMR, Lopes' model emerged as the only one with independent prognostic value while improving the risk stratification proposed by the ASE guidelines.

Cardiac amyloidosis is an infiltrative cardiomyopathy, resulting from amyloid deposition within the myocardium. In primary systemic (AL-type) amyloidosis, the amyloid protein is composed of light chains resulting from plasma-cell dyscrasia, and cardiac involvement occurs in up to 50% of the patients We present a case of a 43-year-old man, with complaints of periodical swollen tongue and xerostomia, bleeding gums and haematuria for two months. His blood results showed normocytic anaemia, thrombocytopenia and a high spontaneous INR, therefore he was referred to the Internal Medicine clinic. In the first visit, he showed signs and symptoms of overt congestive heart failure and was referred to the emergency department. The electrocardiogram showed sinus tachycardia and low voltage criteria. Echocardiography showed biventricular hypertrophy with preserved ejection fraction, restrictive physiology with elevated filling pressures, thickened interatrial septum and atrioventricular valves, small pericardial effusion and relative "apical sparing" on 2D longitudinal strain. Cardiac MRI showed diffuse subendocardial late enhancement. Serum protein electrophoresis was inconclusive, however urine analysis revealed nephrotic range proteinuria, positive Bence Jones protein and an immunofixation test with a monoclonal lambda protein band. Abdominal fat biopsy was negative for Congo red stain, nevertheless a bone marrow biopsy was performed, revealing lambda protein monoclonal plasmocytosis, confirming the diagnosis of primary systemic amyloidosis. This case represents a rare cause of heart failure in a young adult. Low-voltage QRS complexes and typical echocardiography features should raise the suspicion for cardiac amyloidosis. Prognosis is dictated by the level of cardiac involvement; therefore, early diagnosis and treatment are crucial.

The aim of the present study was to evaluate the association between metabolic syndrome (MS) and periodontitis (PD), through a systematic review and meta-analysis. Original observational studies assessing the association between MS and PD in adults, published before May 11th (2017), were identified through electronic searches of MEDLINE, EMBASE and Cochrane Library databases. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline was used. For studies to be included, they had to mention the criteria used to diagnose MS and to have used at least one clinical measure to diagnose PD. There was no language restriction. Three reviewers independently identified eligible studies for possible inclusion in the systematic review and meta-analysis. The quality of the studies was evaluated by the Newcastle-Ottawa scale for observational studies. A random model meta-analysis was conducted. The strategies used to investigate heterogeneity were sequential analysis, subgroup analysis, univariate meta-regression and sensitivity analysis. Thirty-three studies met the inclusion criteria for the systematic review, and 26 had enough information to be included in the meta-analysis, totaling 52,504 patients. MS and PD were associated with an odds ratio of 1.38 (95%CI 1.26-1.51; I2 = 92.7%; p < 0.001). Subgroup analysis showed that complete periodontal examination (I2 = 70.6%; p < 0.001) partially explained the variability between studies. The present findings suggest an association between MS and PD. Individuals with MS are 38% more likely to present PD than individuals without this condition. Prospective studies should be conducted to establish cause and effect relations between MS and PD.

The aim of the present study was to compare negative impacts of oral conditions in Oral Heath Related Quality of Life (OHRQoL) assessed by the Oral Health Impact Profile-14 (OHIP-14) scores in pregnant women receiving or not comprehensive periodontal treatment. This randomized controlled clinical trial included pregnant women aged between 18 and 35 years old. Participants were randomized in a test group with 96 and a control group with 114 women. Patients in the test group received comprehensive periodontal treatment, supra and subgingival scaling and root-planning and periodontal maintenance appointments. The OHIP-14 was applied before and after treatment. The primary outcome was changes in OHIP-14 scores after follow-up period. The impact of having received or not comprehensive periodontal treatment on the change of the OHIP-14 scores was also investigated. Both groups showed significant reduction in OHIP-14 scores and effect size for the test group was 0.60 and 0.36 for the control group. Multinomial logistic regression analysis showed that participants of the control group had 5.9-fold odds (CI 95% 1.88-18.52) of worsening in OHIP-14 scores and their perception of oral conditions in relation to test group. Comprehensive periodontal treatment during pregnancy can reduce the negative impacts in OHRQoL.

BACKGROUND: Zika virus (ZIKV) infection has emerged as a significant threat for pregnant women and newborns in populations living in or visiting Latin America. We previously reported a preliminary analysis in Sucre, Colombia, as the first group of pregnant women with RT-PCR-confirmed ZIKV (ZIKa enEmbarazadas yReciénNacidos enCOLombia, ZIKERNCOL). METHODS: In this second report, findings of the first 86 pregnant women from La Virginia and Dosquebradas (municipalities), Risaralda, Colombia, with RT-PCR-confirmed ZIKV infection are reported. Clinical, demographical and obstetrical findings are described. RESULTS: All women reported ZIKV symptoms during pregnancy: 79.1% rash, 55.8% fever, among others. In addition to ZIKV, RT-PCR was positive for dengue in 18.6%; 45.3% Dengue IgM+; 5.8% RT-PCR positive for chikungunya; 3.6% Chikungunya IgM+. STORCH screening in mother: 11.6% IgG + anti-Toxoplasma gondii, 6% IgG + anti-rubella, 4.7% IgG + CMV. The rest of STORCH tests were negative. Microcephaly was observed in 2.4% of the newborns. No calcifications or other CNS alterations were detected. One newborn had cleft palate and one had bilateral renal ectopy. CONCLUSIONS: The rate of microcephaly in our cohort was consistent with other studies. Pregnant women in endemic areas should be followed and tested according to standard protocols, and asymptomatic ZIKV infection should be considered. Long-term follow-up of children is required in the congenital Zika syndrome (CZS) assessment.

RESUMEN INTRODUCCIÓN: El desarrollo de anticuerpos monoclonales (mAbs) contra el péptido relacionado con el gen de la calcitonina (CGRP) ha determinado una nueva era terapéutica en la profilaxis de migraña, demostrando su efectividad en pacientes con migraña episódica (ME) y migraña crónica (MC), con respuesta desde pacientes naïve hasta refractarios a múltiples medicamentos. La disminución del 50% de los ataques de migraña al mes (DMM) durante los primeros 3 meses de uso es el desenlace aproximado en el 50% de los pacientes que reciben esta terapia. OBJETIVO: Este consenso de la Asociación Colombiana de Neurología (ACN) tiene el objetivo de guiar la selección y uso racional de los mAbs antiCGRP en pacientes con ME y MC. MATERIALES Y MÉTODOS: El comité de cefalea de la ACN mediante la aplicación de la metodología Delphi y discusiones en reuniones posteriores desarrolló un documento en formato de consenso soportado en literatura y recomendaciones de expertos. RESULTADOS: Se obtuvieron respuestas de 14 expertos en cefalea sobre moléculas utilizadas en profilaxis de migraña, analizando su aplicabilidad en situaciones clínicas frecuentes. DISCUSIÓN: Los mAbs antiCGRP han demostrado efectividad con adecuado soporte fisiopatológico, considerando que son moléculas de alto precio en una enfermedad de alta prevalencia, existe la necesidad de guíar la selección del paciente que mejor puede beneficiarse de su administración CONCLUSIONES: Los mAbs antiCGRP están recomendados en pacientes con ME y MC que presentan falla terapéutica a otras moléculas profilácticas.
ABSTRACT INTRODUCTION: The development of monoclonal antibodies (mAbs) against Calcitonin Gene Related Peptide (CGRP) has determined a new therapeutic era in migraine prophylaxis, demonstrating its effectiveness in patients with episodic migraine (EM) and chronic migraine (CM), obtaining a response in naive patients and in those who are refractory to multiple medications. A 50% decrease in migraine attacks per month during the first 3 months of use is the approximate outcome in 50% of patients receiving this therapy. OBJECTIVE: This consensus from the Colombian Association of Neurology (ACN) has the objective of serving as a guide for the rational use of antiCGRP mAbs in patients with EM and CM. METHODS AND MATERIALS: The headache committee through the application of the Delphi methodology and discussions in subsequent meetings, develops this consensus, supported in the published literature and expert recommendations. RESULTS: Fourteen answers from headache experts were received regarding the use of drugs for migraine prophylaxis, analyzing their applicability in frequent clinical situations. DISCUSSION: AntiCGRP mAbs have proved their effectiveness with adequate pathophysiological support, but with a high price in a highly prevalent disease, there is then a need to select the patient who best benefits from this therapy. CONCLUSIONS: AntiCGRP mAbs are recommended in patients with EM and CM that have previously failed to other prophylactic drugs.

Pneumococcal endocarditis is a rare entity, corresponding to 1 to 3% of native valve endocarditis cases. It has a typically adverse prognosis, with high mortality. There is a reported predilection for the aortic valve; thus, a common presentation is acute left heart failure. We present a case of a 60-year-old woman with a history of sinusitis, who was admitted with the diagnosis of pneumonia. She rapidly deteriorated with signs of septic shock and was transferred to the critical care unit. The transesophageal echocardiogram revealed severe aortic regurgitation due to valve vegetations. Blood cultures were positive for Streptococcus pneumoniae. She underwent cardiac surgery and had multiple postoperative complications. Nonetheless, the patient made a slow and complete recovery. Infectious endocarditis should be ruled out if any suspicion arises, and echocardiography should be performed in an early stage in patients with poor response to vasopressors and inotropes. Patients with pneumococcal endocarditis benefit from an aggressive approach, with performance of early surgery.

Constrictive pericarditis is a clinical condition characterized by the appearance of signs and symptoms of right heart failure due to loss of pericardial compliance. Cardiac surgery is now one of the most frequent causes in developed countries, while tuberculosis remains the most prevalent cause in developing countries. Malignancy is a rare cause but usually has a poor prognosis. The diagnosis of constrictive pericarditis remains a clinical challenge and requires a combination of noninvasive diagnostic methods (echocardiography, cardiac magnetic resonance and computed tomography); in some cases, cardiac catheterization is needed to confirm the diagnosis. The authors present the case of a 51-year-old man, hospitalized due to cardiac tamponade. Diagnostic investigation was suggestive of tuberculous etiology. Despite directed medical therapy, the patient developed effusive-constrictive physiology. He underwent pericardiectomy and anatomopathologic study suggested a neoplastic etiology. The patient died in the postoperative period from biventricular failure.

RESUMEN La cefalea relacionada con la actividad física no es infrecuente. En pacientes jóvenes suele corresponder a cefalea por esfuerzo físico primaria. Sin embargo, aun en la presencia de características típicas, el diagnóstico de cefalea primaria relacionada con el ejercicio debe hacerse luego de una investigación exhaustiva. Las causas secundarias típicas incluyen hemorragia subaracnoidea, síndrome de vasoconstricción cerebral reversible y disección arterial. Una etiología menos común es la trombosis de senos venosos durales. En esta revisión presentamos el caso de una mujer joven que experimentó cefalea durante una prueba física, en quien se documenta una trombosis de senos venosos extensa.
SUMMARY Headache related to physical activity is not uncommon. In young patients it usually corresponds to headache due to primary physical exertion. However, even in the presence of typical features, the diagnosis of primary exercise-related headache should be made after extensive investigation. Secondary causes include subarachnoid hemorrhage, reversible cerebral vasoconstriction syndrome, and arterial dissection. A less common etiology is thrombosis of the dural venous sinuses. In this review we present the case of a young woman who presented with headache during a physical test in which extensive venous sinus thrombosis was documented.

SUMMARY INTRODUCTION: Chronic daily headache is a high impact entity in the general population. Although chronic migraine and tension-type headache are the most frequent conditions, it is necessary to consider hemicrania continua and new daily persistent headache as part of the differential diagnoses to perform a correct therapeutic approach. OBJECTIVE: To make recommendations for the treatment of chronic daily headache of primary origin METHODOLOGY: The Colombian Association of Neurology, by consensus and Grade methodology (Grading of recommendations, assessment, development and evaluation), presents the recommendations for the preventive treatment of each of the entities of the daily chronic headache of primary origin group. RESULTS: For the treatment of chronic migraine, the Colombian Association of Neurology recommends onabotulinum toxin A, erenumab, topiramate, flunarizine, amitriptyline, and naratriptan. In chronic tension-type headache the recommended therapeutic options are amitriptyline, imipramine, venlafaxine and mirtazapine. Topiramate, melatonin, and celecoxib for the treatment of hemicrania continua. Options for new daily persistent headache include gabapentin and doxycycline. The recommendations for inpatient treatment of patients with chronic daily headache and the justifications for performing neural blockades as a therapeutic complement are also presented. CONCLUSION: The therapeutic recommendations for the treatment of chronic daily headache based on consensus methodology and Grade System are presented.
