Establishing an ad hoc COVID-19 mortality surveillance during the first epidemic wave in Belgium, 1 March to 21 June 2020.

BackgroundCOVID-19-related mortality in Belgium has drawn attention for two reasons: its high level, and a good completeness in reporting of deaths. An ad hoc surveillance was established to register COVID-19 death numbers in hospitals, long-term care facilities (LTCF) and the community. Belgium adopted broad inclusion criteria for the COVID-19 death notifications, also including possible cases, resulting in a robust correlation between COVID-19 and all-cause mortality.AimTo document and assess the COVID-19 mortality surveillance in Belgium.MethodsWe described the content and data flows of the registration and we assessed the situation as of 21 June 2020, 103 days after the first death attributable to COVID-19 in Belgium. We calculated the participation rate, the notification delay, the percentage of error detected, and the results of additional investigations.ResultsThe participation rate was 100% for hospitals and 83% for nursing homes. Of all deaths, 85% were recorded within 2 calendar days: 11% within the same day, 41% after 1 day and 33% after 2 days, with a quicker notification in hospitals than in LTCF. Corrections of detected errors reduced the death toll by 5%.ConclusionBelgium implemented a rather complete surveillance of COVID-19 mortality, on account of a rapid investment of the hospitals and LTCF. LTCF could build on past experience of previous surveys and surveillance activities. The adoption of an extended definition of 'COVID-19-related deaths' in a context of limited testing capacity has provided timely information about the severity of the epidemic.

[Predictive value of dipyridamole myocardial perfusion tomography on survival]. / Estratificación de riesgo de muerte a mediano plazo de pacientes evaluados por enfermedad coronaria con SPECT de perfusión miocárdica bajo efecto de dipiridamol.

BACKGROUND: Dipyridamole (DIP) is the most commonly employed pharmacological stressor for myocardial perfusion tomography (SPECT) in patients unable to reach an adequate work load. AIM: To assess the predictive capacity of DIP SPECT on survival. MATERIAL AND METHODS: We included 985 adults aged 66 ±11 years (45% women) with rest and DIP-SPECT. The main indications for the procedure were coronary artery disease (CAD) screening in 66% and known CAD in 33%. Participants were followed up for a median of 65 months (interquartile range 54 to 86 months). During the follow up, 261 deaths were recorded and 98% had a specified cause in their death certificate. RESULTS: Myocardial SPECT was abnormal in 44% of participants. Transient ischemic defects were observed in 34%, fixed defects concordant with infarction in 27% and post-stress systolic dysfunction in 23%. Twenty five percent of deaths were attributable to cardiac or ischemic cause and 22% to cancer. In a bivariate analysis, the hazard ratio (HR) of death of any cause was lower in females and higher in the presence of CAD. The multivariate analysis showed that being older than 46 years increased the HR of death of any cause. In a bivariate analysis, the HR for cardiac death was higher when the myocardial SPECT showed ischemia, necrosis or left ventricular dilation. In the multivariate analysis, post-stress left ventricular systolic function was associated with a lower risk of cardiac death. CONCLUSIONS: An abnormal myocardial SPECT, perfusion abnormalities, left ventricular systolic function or dilation are independent predictors of cardiac death in these participants.

[Bone metastases of a gallbladder carcinoma detected by positron emission tomography/computed tomography: Case report]. / Carcinoma vesicular de células en anillo de sello: diseminación poco frecuente: Reporte de un caso con tomografía computada por emisión de positrones con fluor 18-deoxiglucosa.

Signet ring gallbladder carcinoma is a rare aggressive variant of mucinous adenocarcinoma with poor prognosis. Positron emission tomography/computed tomography (PET/CT) with Fluor18 deoxyglucose (F18-FDG) is a useful tool in the staging of gallbladder cancer. We report a 68 years old man with a surgically resected acute cholecystitis, whose biopsy was positive for signet ring cell gallbladder carcinoma. During surgery, locoregional lymph nodes, liver or peritoneal involvement were not detected. A PET/CT was performed for staging, finding multiple hypermetabolic lytic bone lesions. Percutaneous biopsy of a pelvis bone lesion, confirmed a metastasis of the tumor. In this case, the staging with PET/CT allowed the diagnosis of unsuspected bone metastases and was a useful tool for deciding the best site of biopsy for histologic confirmation.

[Pre and intraoperative scintigraphic detection of sentinel nodes in breast cancer]. / Linfonodo centinela en cáncer de mama: correlación entre detección isotópica y quirúrgica.

BACKGROUND: Sentinel node detection localizes the first node that drains a malignant lesion aiming to detect tumor dissemination. AIM: To assess the yield of sentinel node detection in breast cancer, using pre or intraoperative scintigraphy. MATERIAL AND METHODS: Review of medical records of patients with breast cancer who had a scintigraphic detection of sentinel nodes. Lymph node scintigraphy and surgery were performed in the same day. RESULTS: We studied 174 women aged 53 ± 13 years, operated with a diagnosis of breast cancer, including six highly suspicious lesions in the contralateral breast (totaling 180 studied breasts). Preoperative scintigraphy showed a sentinel node in 174 of 180 breasts (97%). Intraoperative gamma probe confirmed the presence of the sentinel node in the same 174 breasts and detected an additional one reaching a detection yield of 97%. Four patients in whom a sentinel node was not detected in the preoperative scintigraphy, had macrometastases. Frozen section biopsies were available in 177 of 180 breasts. Metastases were informed in 45 patients who underwent axillary lymph node dissection, plus one additional patient with a suspicious lesion. CONCLUSIONS: A high rate of sentinel node detection in the preoperative scintigraphy was observed. Most sentinel nodes not detected with nuclear medicine had macrometastases. In 71% of patients, the detection of sentinel node avoided axillary lymph node dissection.

[Follow-up of patients with good exercise capacity in stress test with myocardial single-photon emission computed tomography (SPECT)]. / Seguimiento clínico en pacientes con buena capacidad metabólica en la prueba de esfuerzo con SPECT miocárdico.

BACKGROUND: The evaluation of coronary artery disease (CAD) can be performed with stress test and myocardial SPECT tomography. AIM: To assess the predictive value of myocardial SPECT using stress test for cardiovascular events in patients with good exercise capacity. MATERIAL AND METHODS: We included 102 males aged 56 ± 10 years and 19 females aged 52 ± 10 years, all able to achieve 10 METs and ≥ 85% of the theoretical maximum heart rate and at least 8 min in their stress test with gated 99mTc-sestamibi SPECT. Eighty two percent of patients were followed clinically for 33 ± 17 months. RESULTS: Sixty seven percent of patients were studied for CAD screening and the rest for known disease assessment. Treadmill stress test was negative in 75.4%; 37% of patients with moderate to severe Duke Score presented ischemia. Normal myocardial perfusion SPECT was observed in 70.2%. Reversible defects appeared in 24.8% of cases, which were of moderate or severe degree (> 10% left ventricular extension) in 56.6%. Only seven cases had coronary events after the SPECT. Two major (myocardial infarction and emergency coronary revascularization) and 5 minor events (elective revascularization) ere observed in the follow-up. In a multivariate analysis, SPECT ischemia was the only statistically significant parameter that increased the probability of having a major or minor event. CONCLUSIONS: Nearly a quarter of our patients with good exercise capacity demonstrated reversible defects in their myocardial perfusion SPECT. In the intermediate-term follow-up, a low rate of cardiac events was observed, being the isotopic ischemia the only significant predictive parameter.

Effectiveness of Duloxetine versus Other Therapeutic Modalities in Patients with Diabetic Neuropathic Pain: A Systematic Review and Meta-Analysis.

Objectives: Diabetic peripheral neuropathy (DPN) is a chronic complication of diabetes mellitus (DM) with symptoms like intense pain and impaired quality of life. This condition has no treatment; instead, the pain is managed with various antidepressants, including duloxetine. The aim of this study is to analyze the evidence on the efficacy of duloxetine in the management of DPN. Methods: A systematic search in different databases was conducted using the keywords "diabetic neuropathy", "duloxetine therapy", "neuropathic pain", and "Diabetes Mellitus". Finally, eight studies were included in this meta-analysis. Results: All articles comparing duloxetine at different doses vs. a placebo reported significant differences in favor of duloxetine on pain scales like 24 h Average Pain Severity (standardized mean difference [SMD] = -1.06, confidence interval [CI] = -1.09 to -1.03, and p < 0.00001) and BPI Severity (SMD = -0.70, CI = -0.72 to -0.68, and p < 0.00001), among others. A total of 75% of the meta-analyses of studies comparing duloxetine at different doses showed a tendency in favor of the 120 mg/d dose. There were significant differences in favor of duloxetine when compared to routine care on the Euro Quality of Life (SMD = -0.04, CI = -0.04 to -0.03, and p < 0.00001) and SF-36 Survey (SMD = -5.86, CI = -6.28 to -5.44, and p < 0.00001) scales. There were no significant differences on the visual analog scale (VAS) when comparing duloxetine and gabapentin. Conclusions: Duloxetine appears to be effective in the management of DPN in different pain, symptom improvement, and quality of life scales.

A retrospective study of Cerebrolysin in patients with moderate to severe traumatic brain injury: Cognitive and functional outcomes.

In this retrospective study, we aimed to evaluate the effects of the neurotrophic compound Cerebrolysin on executive, cognitive, and functional performance in patients with traumatic brain injury (TBI) with a highly severe disability level. A total of 44 patients were included in the study, with 33 patients in the control group and 11 patients in the interventional group who received intravenous infusions of 30 mL Cerebrolysin. Both groups received standard rehabilitation therapy following the rehabilitation protocol for patients with TBI at Hospital Clínico Mutual de Seguridad. Functional and cognitive scales were evaluated at baseline, at four months, and at the endpoint of the intervention therapy at seven months (on average). The results revealed a significant improvement in the Cerebrolysin-treated group compared to the control group. Specifically, patients who received Cerebrolysin showed a moderate residual disability and a significant reduction in the need for care. Concerning the promising results and considering the limitations of the retrospective study design, we suggest that randomized controlled studies be initiated to corroborate the positive findings for Cerebrolysin in patients with moderate to severe brain trauma.

Probenecid, an Old Drug with Potential New Uses for Central Nervous System Disorders and Neuroinflammation.

Probenecid is an old uricosuric agent used in clinics to treat gout and reduce the renal excretion of antibiotics. In recent years, probenecid has gained attention due to its ability to interact with membrane proteins such as TRPV2 channels, organic anion transporters, and pannexin 1 hemichannels, which suggests new potential therapeutic utilities in medicine. Some current functions of probenecid include their use as an adjuvant to increase the bioavailability of several drugs in the Central Nervous System (CNS). Numerous studies also suggest that this drug has important neuroprotective, antiepileptic, and anti-inflammatory properties, as evidenced by their effect against neurological and neurodegenerative diseases. In these studies, the use of probenecid as a Panx1 hemichannel blocker to reduce neuroinflammation is highlighted since neuroinflammation is a major trigger for diverse CNS alterations. Although the clinical use of probenecid has declined over the years, advances in its use in preclinical research indicate that it may be useful to improve conventional therapies in the psychiatric field where the drugs used have a low bioavailability, either because of a deficient passage through the blood-brain barrier or a high efflux from the CNS or also a high urinary clearance. This review summarizes the history, pharmacological properties, and recent research uses of probenecid and discusses its future projections as a potential pharmacological strategy to intervene in neurodegeneration as an outcome of neuroinflammation.

COVID-19 cases, hospitalizations and deaths in Belgian nursing homes: results of a surveillance conducted between April and December 2020.

BACKGROUND: In Belgium, the first COVID-19 death was reported on 10 March 2020. Nursing home (NH) residents are particularly vulnerable for COVID-19, making it essential to follow-up the spread of COVID-19 in this setting. This manuscript describes the methodology of surveillance and epidemiology of COVID-19 cases, hospitalizations and deaths in Belgian NHs. METHODS: A COVID-19 surveillance in all Belgian NHs (n = 1542) was set up by the regional health authorities and Sciensano. Aggregated data on possible/confirmed COVID-19 cases and hospitalizations and case-based data on deaths were reported by NHs at least once a week. The study period covered April-December 2020. Weekly incidence/prevalence data were calculated per 1000 residents or staff members. RESULTS: This surveillance has been launched within 14 days after the first COVID-19 death in Belgium. Automatic data cleaning was installed using different validation rules. More than 99% of NHs participated at least once, with a median weekly participation rate of 95%. The cumulative incidence of possible/confirmed COVID-19 cases among residents was 206/1000 in the first wave and 367/1000 in the second wave. Most NHs (82%) reported cases in both waves and 74% registered ≥10 possible/confirmed cases among residents at one point in time. In 51% of NHs, at least 10% of staff was absent due to COVID-19 at one point. Between 11 March 2020 and 3 January 2021, 11,329 COVID-19 deaths among NH residents were reported, comprising 57% of all COVID-19 deaths in Belgium in that period. CONCLUSIONS: This surveillance was crucial in mapping COVID-19 in this vulnerable setting and guiding public health interventions, despite limitations of aggregated data and necessary changes in protocol over time. Belgian NHs were severely hit by COVID-19 with many fatal cases. The measure of not allowing visitors, implemented in the beginning of the pandemic, could not avoid the spread of SARS-CoV-2 in the NHs during the first wave. The virus was probably often introduced by staff. Once the virus was introduced, it was difficult to prevent healthcare-associated outbreaks. Although, in contrast to the first wave, personal protective equipment was available in the second wave, again a high number of cases were reported.

The Long-Term Pannexin 1 Ablation Produces Structural and Functional Modifications in Hippocampal Neurons.

Enhanced activity and overexpression of Pannexin 1 (Panx1) channels contribute to neuronal pathologies such as epilepsy and Alzheimer's disease (AD). The Panx1 channel ablation alters the hippocampus's glutamatergic neurotransmission, synaptic plasticity, and memory flexibility. Nevertheless, Panx1-knockout (Panx1-KO) mice still retain the ability to learn, suggesting that compensatory mechanisms stabilize their neuronal activity. Here, we show that the absence of Panx1 in the adult brain promotes a series of structural and functional modifications in the Panx1-KO hippocampal synapses, preserving spontaneous activity. Compared to the wild-type (WT) condition, the adult hippocampal neurons of Panx1-KO mice exhibit enhanced excitability, a more complex dendritic branching, enhanced spine maturation, and an increased proportion of multiple synaptic contacts. These modifications seem to rely on the actin-cytoskeleton dynamics as an increase in the actin polymerization and an imbalance between the Rac1 and the RhoA GTPase activities were observed in Panx1-KO brain tissues. Our findings highlight a novel interaction between Panx1 channels, actin, and Rho GTPases, which appear to be relevant for synapse stability.

Hip Fractures in the Elderly During the COVID-19 Pandemic: A Latin-American Perspective With a Minimum 90-Day Follow-Up.

INTRODUCTION: Hip fracture patients have been severely affected by the COVID-19 pandemic; however, the sub acute effects of a concomitant SARS-CoV-2 infection and the outcomes in highly exposed developing countries are still unknown. Our objective is to describe the morbidity and mortality of elderly patients admitted for a hip fracture during the COVID-19 pandemic in Chile, with a minimum 90-day follow-up. Also, to elucidate predictors for mortality and to compare mortality results with the pre-pandemic era. MATERIAL AND METHODS: Multicentric retrospective review of patients admitted for a fragility hip fracture in 3 hospitals during the COVID-19 pandemic, and during the same time in 2019. All clinical information and images were recorded, and patients were followed for a minimum of 90-days. Morbidity and mortality were the primary outcomes. Uni/multivariable models were performed to elucidate predictors for mortality utilizing the Weibull's regression. RESULTS: Three hundred ninety-one cases were included. From the 2020 cohort (162 patients), 24 (15%) had a concomitant SARS-CoV-2 infection. Fourteen patients (58%) tested positive after admission. The COVID-19(+) group had a higher risk of in-hospital, 30-day, and 90-day mortality (p < 0.001). They also had a prolonged hospital stay and presented with more complications and readmissions (p < 0.05). Only COVID-19(+) status and older age were independent predictors for mortality with a HR = 6.5 (p = < 0.001) and 1.09 (p = 0.001), respectively. The 2020 cohort had twice the risk of mortality with a HR = 2.04 (p = 0.002) compared to the 2019 cohort. However, comparing only the COVID-19 (-) patients, there was no difference in mortality risk, with a HR = 1.30 (p = 0.343). DISCUSSION: The COVID-19 pandemic has significantly affected healthcare systems and elderly patients. CONCLUSIONS: Hip fracture patients with a concomitant SARS-CoV-2 virus infection were associated with increased morbidity and mortality throughout the first 3 months. COVID-19 status and older age were significant predictors for mortality. Efforts should be directed into nosocomial infection reduction and prompt surgical management. LEVEL OF EVIDENCE: Level III.

Management of patients with low back pain in the emergency department: Is it feasible to follow evidence-based recommendations?

OBJECTIVE: Low back pain is frequently seen in patients visiting the ED, but many patients receive medical care with no demonstrable benefits. We studied the clinical characteristics of patients visiting two EDs in Santiago, Chile, and their management to evaluate how it adheres to evidence-based recommendations. METHODS: We studied 519 patients and retrieved their demographic and clinical data, imaging testing and treatments. We determined the effect of sex, age, time from initial symptoms, pain measured with the visual analogue scale, presence of nerve radiation and the presence of red flags and neurological impairment on image testing and the management received. RESULTS: Mean age was 43.8 years; 57.8% were females. Females presented more often red flags (7.3 vs 3%, P = 0.04) and worse pain (visual analogue scale = 7 vs 6, P = 0.04) than males. Imagings were performed in 18.9% of patients; they were more frequently performed in patients with neurological impairment (P = 0.03) and red flags (P = 0.01). Intravenous non-opioids were administered in 25.6%; opioids were administered in 40.1%. Median time in the ED was 91 min (range 18-591); 16 (3.08%) patients were admitted. Age (odds ratio [OR] 1.04 [1.03-1.05], P < 0.01) and red flags (OR 4.9 [1.60-20.08], P < 0.01) influenced imaging testing; pain intensity influenced opioid use (OR 1.6 [1.29-1.95], P < 0.01), hospital admissions (1.95 [1.14-3.33], P < 0.01) and time in the ED (ß = 0.5, P < 0.01). CONCLUSION: Older age, the presence of red flags and pain intensity influenced the management of patients with low back pain in the ED. Future strategies should emphasise avoiding costly and ineffective management in these patients.

Rapid establishment of a national surveillance of COVID-19 hospitalizations in Belgium.

BACKGROUND: In response to the COVID-19 epidemic, caused by a novel coronavirus, it was of great importance to rapidly collect as much accurate information as possible in order to characterize the public health threat and support the health authorities in its management. Hospital-based surveillance is paramount to monitor the severity of a disease in the population. METHODS: Two separate surveillance systems, a Surge Capacity survey and a Clinical survey, were set up to collect complementary data on COVID-19 from Belgium's hospitals. The Surge Capacity survey collects aggregated data to monitor the hospital capacity through occupancy rates of beds and medical devices, and to follow a set of key epidemiological indicators over time. Participation is mandatory and the daily data collection includes prevalence and incidence figures on the number of COVID-19 patients in the hospital. The Clinical survey is strongly recommended by health authorities, focusses on specific patient characteristics and relies on individual patient data provided by the hospitals at admission and discharge. CONCLUSIONS: This national double-level hospital surveillance was implemented very rapidly after the first COVID-19 patients were hospitalized and revealed to be crucial to monitor hospital capacity over time and to better understand the disease in terms of risk groups and outcomes. The two approaches are complementary and serve different needs.

Do your gut microbes affect your brain dopamine?

Increasing evidence shows changes in gut microbiota composition in association with psychiatric disorders, including anxiety and depression. Moreover, it has been reported that perturbations in gut microbe diversity and richness influence serotonergic, GABAergic, noradrenergic, and dopaminergic neurotransmission. Among these, dopamine is regarded as a main regulator of cognitive functions such as decision making, attention, memory, motivation, and reward. In this work, we will highlight findings that link alterations in intestinal microbiota and dopaminergic neurotransmission, with a particular emphasis on the mesocorticolimbic circuit, which is involved in reward to natural reinforcers, as well as abuse substances. For this, we reviewed evidence from studies carried out on germ-free animals, or in rodents subjected to intestinal dysbiosis using antibiotics, and also through the use of probiotics. All this evidence strongly supports that the microbiota-gut-brain axis is key to the physiopathology of several neuropsychiatric disorders involving those where dopaminergic neurotransmission is compromised. In addition, the gut microbiota appears as a key player when it comes to proposing novel strategies to the treatment of these psychiatric conditions.

Manejo odontológico de pacientes con el síndrome de Ehlers-Danlos. Revisión narrativa / Dental management in patients with Ehlers-Danlos syndrome. Narrative review

Resumen El síndrome de Ehlers-Danlos es una enfermedad hereditaria, producida por mutaciones cromosómicas que pueden llegar a tener un comportamiento autosómico dominante, recesivo o ligado al cromosoma X. Se caracteriza por defectos en las enzimas encargadas de la estructura y síntesis de colágeno. En vista de los 20 tipos de colágeno que existen, este síndrome es extremadamente heterogéneo tanto en su presentación clínica como en su progresión y evolución. Dentro de los signos y síntomas habituales encontramos la hiperlaxitud articular, hiperelasticidad de la piel e hiperequimosis de los vasos sanguíneos. Con relación a las complicaciones que pueden presentar estos pacientes, encontramos dislocaciones articulares, fragilidad en la piel, dolor articular, ruptura de grandes vasos sanguíneos, dificultad en la cicatrización y, en consecuencia, mayor incidencia de procesos infecciosos y de cicatrices poco estéticas. Presenta una incidencia de 1 caso cada 2.500-5.000 nacidos vivos. Por ello, es fundamental que el odontólogo se encuentre familiarizado con el manejo médico-dental de estos pacientes, a fin de estar preparado para brindarles un tratamiento adecuado y responder ante las posibles complicaciones que se pueden presentar. En esta revisión se emplearon resultados extraídos manualmente de artículos, indexados en las bases de datos PUBMED y EBSCO, que respondían a la búsqueda de los términos Ehlers-Danlos syndrome, dental management y oral surgery. El objetivo fue describir el manejo médico-odontológico del paciente con síndrome de Ehlers-Danlos hasta la fecha.

Abstract Ehlers-Danlos syndrome is a hereditary disease, produced by chromosomal mutations that can have an autosomal behavior, which can be dominant, recessive or X-linked. It is characterized by defects in the enzymes responsible for the structure and synthesis of collagen. In view of the 20 existent types of collagen, this syndrome is extremely heterogeneous in its clinical presentation, as well as in its progression and evolution. Within the usual signs and symptoms, we find joint hyperlaxity, skin hyperelasticity and hyper-ecchymosis of the blood vessels. Regarding the complications that these patients can present, we find joint dislocations, skin fragility, joint pain, rupture of large blood vessels, difficulty in healing and, consequently, a higher incidence of infectious processes and unsightly scars. It presents an incidence of 1 case every 2.500-5.000 live births. Therefore, it is essential that the dentist is familiar with the medical-dental management of these patients, in order to be prepared to provide them with adequate treatment and respond to possible complications that may arise. In this review, results were manually extracted from articles, indexed in the PUBMED and EBSCO databases, that respond to the search for the terms Ehlers-Danlos syndrome, dental management and oral surgery. The aim was describing the medical-dental management of patients with Ehlers-Danlos syndrome to date.

Abstract Objective To know the occupational repercussions caused by hemodialysis treatment in people suffering from Terminal Chronic Kidney Disease and how public policies in Chile, specifically, Explicit Health Guarantees address the needs of this population. Method Environmental observation guidelines, field notes, and semi-structured interviews with users and professionals who work in the Hemodialysis Unit of the Hospital Base de Valdivia, Chile were used. In addition, a documentary analysis was carried out that included clinical guidelines and technical standards of the Hemodialysis Unit. Results The data were organized into 5 topics: Hospital Base Valdivia hemodialysis unit, Process of change and adaptation, Routines and habits, Roles and Sufficiency of public policies. Breaks in occupational histories, difficulties in the adaptation process and the need for a comprehensive approach that is not considered by public policies are evidenced. Conclusion The need for a multidisciplinary treatment is proposed that considers an accompaniment in the process of occupational adaptation, especially in the early stages after diagnosis in order to prevent the impact on the quality of life of this population, as well as the need to develop more studies on the subject.

Evaluation of a telemedicine program in oral pathology and preventive oral examination in Hualqui Municipality, Chile

ABSTRACT: Introduction: A telemedicine program in oral pathology (TOP) and a preventive oral examination (POE) to identify oral lesions was implemented in Hualqui, Chile. The objective of this study is to describe the results of the TOP plus POE strategy at CESFAM Hualqui, Chile, during the period of 2016 to 2019. Materials and methods: A prospective cohort study was conducted with 152 Hualqui patients between 2016 and 2019. The following variables were recorded: diagnosis; injury diagnosis dates; date of teleconsultation; date and response of the specialist and subsequent control; waiting time for response (WTR) and waiting time for attention (WTA). Results: The WTR was 19.7 ± 12.8 days and WTA presented a median of 20 days (1−125) days. A total of 45 different oral pathologies were identified, the most frequent being stomatitis 8.6% (13), fibroma 8.6% (13) and mucocele 7.9% (12), and among the least frequent highlights three cases of oral cancer. Conclusions: The waiting periods until a response from the specialist and then until the face-to-face control were around 3 weeks each, most of the cases were identified through POE and correspond mostly to benign pathologies.
