ABSTRACT

Osteoporosis, and the consequences derived from it, such as fragility fractures, constitute a growing public health problem. Suffering from a fracture of this nature is the main risk factor for suffering a new fracture. It is documented that vertebral compression fractures lead to significant morbidity and mortality, in the short and long term, as well as other complications, such as sagittal imbalance and hyperkyphosis of the segment. However, we have not found documentation that analyzes the medium and long-term consequences of these injuries, assessing the type of treatment used, and the economic impact they represent. The purpose of this review is to analyze the main recent literature on the subject and make a breakdown of the consequences of these fractures in various spheres, such as economic, quality of life, sagittal balance and radiographic parameters, pain or mortality; as well as a brief analysis of epidemiology and natural history. CONCLUSION: Osteoporotic fractures constitute an emerging problem, both in the medical and economic fields. The consequences and sequelae on the patient are multiple and although surgical options offer good long-term results, it is necessary to properly select the patient, through multidisciplinary teams, to try to minimize potential complications.

ABSTRACT

BACKGROUND AND OBJECTIVE: People with disabilities are one of the groups that usually frequent healthcare centers, so it is essential to attend to their specific needs, especially from the point of view of universal accessibility, safety and healthcare quality. The aim of the study is to summarize the available evidence on the needs of groups of patients with some type of disability in access, navigation and stay during the reception of healthcare in various health centers and to identify successful solutions. MATERIALS AND METHODS: A scoping review had been designed, based on a literature review without time limit in three databases (PubMed, WOS, and Embase). RESULTS: Of the 2562 articles identified, 11 were included. Recommendations for improvement in the design of healthcare services focused on the following aspects: improving access to primary care centers; navigation, signage, and orientation in the hospital environment; elevator design; hospital room bathroom design; meeting the needs of wheelchair users; importance of the participation of the patient with a disability; involvement of stakeholders in the design process; and the need for appropriate policies to ensure accessibility to buildings. CONCLUSIONS: The promotion of artistic programs in healthcare settings and the participation of people with disabilities in the design process of healthcare settings could provide beneficial solutions. More studies are needed, given the scarcity of evidence found, to ensure that care for this group is based on criteria of patient safety, universal accessibility, healthcare quality and humanization.

ABSTRACT

BACKGROUND: Inflammatory biomarkers, including C-reactive protein, erythrocyte sedimentation rate, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, and the systemic immune-inflammation index, have been proposed as prognostic factors diverse pathologies. However, their application for deep neck infections has yet to be clarified. MATERIAL AND METHODS: We performed a retrospective study of 163 adult patients with diagnosis of deep neck infections with the aim to evaluate the association between serological biomarkers with complications and outcomes of patients with DNI. Studied variables included demographic data, complications of DNI, outcomes, complications and death of the included subjects. The evaluated serological biomarkers were hemoglobin, leukocytes, neutrophils, lymphocytes, platelets, glucose, creatinine, albumin, CRP, and ESR. NLR, PLR, and SIII index were estimated. RESULTS: The patients' mean age was 40.6 ± 15.3 years. Complications of DNI were observed in 19.6% (n=32) patients, being the need for tracheostomy due to airway obstruction (11%, n=18) and mediastinitis (8.6%, n= 14) the most common. Evaluated subjects had an increased value of serological biomarkers (SII index 2639.9 ± 2062.9, NLR 11.3 ± 8.5, PLR 184.1 ± 108.5, CRP 12.6 ± 8.9 mg/dL, ESR 20.7 ± 9.1 mm/h). Patients with complications had a significantly higher value of all inflammatory parameters (p < 0.05). A SII index cut-off value of 2975 was selected from a ROC curve analysis. A sensitivity of 93.8%, specificity of 86.3%, a positive predictive value of 62.5%, and a negative predictive value of 98.3% are reported. The SII index was found to have an increased positive predictive value compared to NLR, PLR, and CRP for DNI complications. CONCLUSIONS: Our analysis concluded that the SII index, NLR, and PLR are valuable biomarkers to assess the risk of complications from DNI. SII index showed a high accuracy for prediction of DNI complications with a cut-off value of 2975.

ABSTRACT

Las metástasis espinales representan una importante carga sobre la calidad de vida en los pacientes afectados por una enfermedad oncológica activa, debido a la alta incidencia de síndromes dolorosos, deformidad espinal y deterioro neurológico. La cirugía juega un papel determinante a la hora de mejorar la calidad de vida mediante el control del dolor, el restablecimiento de la función neurológica y el mantenimiento de la estabilidad espinal, además de contribuir a la respuesta de la terapia médica. La cirugía mínimamente invasiva (MIS) es una opción de tratamiento en determinados pacientes con alto riesgo quirúrgico, ya que tiene una baja tasa de complicaciones, de sangrado intraoperatorio, de estancia hospitalaria y ofrece resultados similares a la cirugía abierta. Presentamos en esta revisión el papel de la MIS en esta enfermedad, y algunos casos tratados en nuestro centro hospitalario.(AU)


Spinal metastases represent a significant burden on the quality of life in patients affected by active oncological disease due to the high incidence of pain syndromes, spinal deformity, and neurological impairment. Surgery plays a decisive role in improving quality of life by controlling pain, restoring neurological function and maintaining spinal stability, as well as contributing to the response to medical therapy. Minimally invasive surgery (MIS) is a treatment option in certain patients with high surgical risk since it has a low rate of complications, intraoperative bleeding, hospital stay, and offers similar results to open surgery. In this review, we present the role of MIS in this pathology and some cases treated in our hospital.(AU)

ABSTRACT

Nowadays, atom-based quantum sensors are leaving the laboratory towards field applications requiring compact and robust laser systems. Here we describe the realization of a compact laser system for atomic gravimetry. Starting with a single diode laser operating at 780 nm and adding only one fiber electro-optical modulator, one acousto-optical modulator and one laser amplifier we produce laser beams at all the frequencies required for a Rb-87 atomic gravimeter. Furthermore, we demonstrate that an atomic fountain configuration can also be implemented with our laser system. The modulated system reported here represents a substantial advance in the simplification of the laser source for transportable atom-based quantum sensors that can be adapted to other sensors such as atomic clocks, accelerometers, gyroscopes or magnetometers with minor modifications.

ABSTRACT

OBJECTIVE: The prevalence of the optic canal anatomical variants across the sphenoid sinus varies widely among different ethnic groups. This study aimed to analyse the anatomical variants of the optic canal and their relationship to sphenoid sinus pneumatisation in a Hispanic population. METHOD: A review of 320 sphenoid sinuses by high-resolution computed tomography was performed. DeLano's classification of the optic canal, presence of dehiscence, septa insertion, sphenoid sinus pneumatisation and presence of Onodi cells were established. RESULTS: Dehiscence of the optic canal was observed in 4.7 per cent (n = 15) of the analysed sinuses. Type 4 and 3 optic canals were significantly more frequent among postsellar sphenoid sinuses than other patterns of sphenoid sinus pneumatisation (p = 0.002 and p = 0.018). A type 4 optic canal has a higher tendency to present inserted septum than other optic canal types (p = 0.014). CONCLUSION: This study described the optic canal variants in a Hispanic population, which complements existing literature addressing other ethnicities.

ABSTRACT

BACKGROUND: There are developmental variations in the paranasal sinuses. Our objective was to determine their dimensions and volume stratified by age and sex and define the expected growth pattern. MATERIALS AND METHODS: A retrospective, observational study was performed including computed tomography (CT) of patients between 1 and 20 years of age. The volumes of the frontal, sphenoid, and maxillary sinuses were obtained. RESULTS: A total of 210 CT were included with a mean age of 10 ± 6.1 years, 106 (50.5%) were female. Groups were categorised in ranges of 5 years. Spearman correlation coefficients between the right and left sides were 0.843, 0.711, 0.916 for the frontal, sphenoid and maxillary sinuses. Post-hoc for the categorical age groups demonstrated statistically significant differences with values of p < 0.01, except between age groups 11-15 against ≥ 16 years of age (p = 0.8). Gender-related differences were evident with a higher air volume in girls in the 5-10-year-old group, while boys predominated in the rest of the groups. CONCLUSIONS: Computed tomography is ideal for pre-surgical sinus assessment. The maximum volume of paranasal sinuses is reached at the age of 15. There is a clear volumetric difference between age and gender groups. There is a direct relationship between a volume and its contralateral counterpart.

ABSTRACT

BACKGROUND: Odontogenic deep neck infections remain a common condition that presents a challenging issue due to the complex involvement of the neck and adjacent structures and its potential life-threatening risk. Periapical infection of the second or third molar with spread to the submandibular and parapharyngeal spaces is the most commonly observed scenario. However, the time of dental extraction of the infection focus remains controversial. The aim of this study is to provide an overview of the epidemiology, clinical and radiological features, and management in patients diagnosed with ODNI and to identify the role of early dental extraction on patient outcomes and recovery. MATERIAL AND METHODS: This retrospective study included patients over 18 years old with a diagnosis of ODNI who were admitted to the University Hospital "Dr Jose Eleuterio Gonzalez" from January 2017 to January 2022. ODNI diagnosis was based on clinical and radiological evidence of the disease supplemented by dental and maxillofacial evaluation for an odontogenic aetiology. RESULTS: A total of 68 patients were included in the study. The patients' mean age was 40.96 ± 14.9. Diabetes mellitus was the most common comorbidity. The submandibular space was the most common deep neck space involved (n=59, 86.8%). Mediastinitis, marginal nerve injury and orocervical fistula were observed in 7.5% of patients, with no fatality in this series. A delay of >3 days for dental extraction of the involved tooth was associated with an increased rate of mediastinitis (n=3, 100%, p= 0.022), number of surgical interventions (1.45 ± 0.61, p= 0.006), ICU stay (n=8, 40%, p= 0.019), and ICU length of stay (0.85 ± 0.8, p= 0.001). CONCLUSIONS: Expedited management with surgical drainage and intravenous antibiotic treatment, along with early extraction of the involved tooth, is mandatory.

ABSTRACT

This study aimed to develop Ca2+ doped ZnO nanoparticles (NPs) and investigate their antibacterial properties against microorganisms of dental interest. Zn-Ca NPs were synthesized by the sol-gel method with different concentrations of Ca2+ (1, 3, and 5 wt. %) and subsequently characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-vis spectroscopy and Fourier transform infrared spectroscopy (FT-IR). The Kirby-Bauer method was used to measure antibacterial effects. NPs showed the wurzite phase of ZnO and bandgap energies (Eg) from 2.99 to 3.04 eV. SEM analysis showed an average particle size of 80 to 160 nm. The treatments that presented the best antibacterial activity were Zn-Ca 3% and Zn-Ca 5%. ZnO NPs represent an alternative to generate and improve materials with antibacterial capacity for dental applications.
