A Novel Uni- and Biplanar External Fixator for Initial and Definitive Complex Foot Trauma.

Background: Evidence concerning the complex foot trauma, especially its definitive management, is scarce. Soft tissue envelope sequalae are the primary parameters that delay or make internal fixation implausible. Stability conferred by external fixators makes them a reasonable initial treatment choice. Although AO or circular fixators can be applied around the foot, this can involve a learning curve and substantial costs, especially for the circular fixator. There is little evidence as to how well external fixators work as a definite method of fixation in patients where progression to internal fixation cannot be made. Methods: We prospectively evaluated 10 adult patients with severe and complex foot trauma who were consecutively treated at our clinic. Initial reduction and stabilization were performed with an external fixator that was initially conceived for distal radius fractures, applied during the initial procedure and mantained throughout the treatment. Results: Fracture healing was obtained in all 10 cases, and both internal and external column length was restored. One of the patients developed chronic osteomyelitis. At the 1-year follow-up visit, these patients averaged 45.6 points in the physical and 44.8 points on the mental status sections of the 12-Item Short Form Health Survey (SF-12). The Foot Function Index findings for pain, disability, and daily activities limitations were 33.3, 39, and 41.5, respectively, which suggest moderate residual impairment. Conclusion: In this relatively small case series of complex foot trauma, we found that the use of simple external fixation as definitive treatment worked reasonably well. Level of Evidence: Level III, prospective cohort study.

Research about eye health and eye health services in Pacific Island Countries and Territories: a scoping review.

Background: We aimed to summarise the extent and nature of published research about eye health and eye health services in Pacific Island Countries and Territories since 1980. Methods: We searched Medline, EMBASE, Global Health and Cochrane Library to identify publications about eye health and eye health services in 22 Pacific Island Countries and Territories from 1 January 1980 to 26 January 2024. Study selection and data extraction were conducted by two reviewers independently. Findings: Of the 1610 publications identified, 180 were included. This research was most commonly conducted in Papua New Guinea (n = 52) or Fiji (n = 33) and focused on diabetic retinopathy (n = 29) or trachoma (n = 18), with few focused on cataract or refractive error. While eye health services research was common in the past, recent research focused on trachoma. The included research was largely undertaken and funded by people and organisations from Australia, Aotearoa New Zealand and the USA, though authors with Pacific affiliations is increasing. Interpretation: Few countries have up-to-date estimates of the prevalence of vision impairment or service coverage to enable evidence-informed planning. Increased effort is required to strengthen research capability to ensure research priorities in eye health are set by Pacific Peoples. Funding: The Fred Hollows Foundation New Zealand.

Time-resolved interactome profiling deconvolutes secretory protein quality control dynamics.

Many cellular processes are governed by protein-protein interactions that require tight spatial and temporal regulation. Accordingly, it is necessary to understand the dynamics of these interactions to fully comprehend and elucidate cellular processes and pathological disease states. To map de novo protein-protein interactions with time resolution at an organelle-wide scale, we developed a quantitative mass spectrometry method, time-resolved interactome profiling (TRIP). We apply TRIP to elucidate aberrant protein interaction dynamics that lead to the protein misfolding disease congenital hypothyroidism. We deconvolute altered temporal interactions of the thyroid hormone precursor thyroglobulin with pathways implicated in hypothyroidism pathophysiology, such as Hsp70-/90-assisted folding, disulfide/redox processing, and N-glycosylation. Functional siRNA screening identified VCP and TEX264 as key protein degradation components whose inhibition selectively rescues mutant prohormone secretion. Ultimately, our results provide novel insight into the temporal coordination of protein homeostasis, and our TRIP method should find broad applications in investigating protein-folding diseases and cellular processes.

Dermoscopic Evaluation of Actinic Changes in the Lips of Indigenous Children Living at High Altitude in Ecuador: A Descriptive Study.

BACKGROUND High altitude increases sunlight exposure, resulting in actinic keratosis, which predisposes people to skin cancer. The dermoscopy procedure evaluates keratotic and pigmented skin changes. This study aimed to describe the clinical and dermoscopic actinic changes in the lips of 25 indigenous children living at high altitude in Ecuador. MATERIAL AND METHODS An observational study was conducted in a public school in the Andes region of Ecuador (August-November 2019). Twenty-five children, males and females, age 5-15 years were assessed by complete physical examination, digital dermoscopic photographs, and punch biopsies. Descriptive statistics and Fisher's exact test were used to summarize and analyze the data. RESULTS We included 17 (68%) boys and 8 (32%) girls with a mean age of 9.8±2.0 years. Clinical lips findings reported desquamation [52% Upper Lip (UL); 40% Lower Lip (LL)], fissuring (8% UL; 8% LL), scabs (8% UL; 8% LL), and discoloration (40% UL; 20% LL). Dermoscopic features included a white-yellow lip color (24% UL; p=0.02). The main morphologic pattern of blood vessels was monomorphic (88% UL; p<0.001), polymorphous (60% LL; p<0.001), dotted pattern (64% UL; 28% LL; p=0.02), and linear-irregular (32% UL; 72% LL; p=0.01). Girls had radiating white structures on UL (p=0.025), while boys presented white structureless areas (UL 63.6%; LL 77.8%; p=0.032). No differences in dermoscopic findings were observed according to Fitzpatrick scale score (FSS). Punch biopsies showed no indications of actinic cheilitis. CONCLUSIONS Dermoscopic features in indigenous children living in high altitudes were related to actinic damage, but histopathological findings were negative.

Republication of "How Accurate Is Clinical Evaluation in Hindfoot Coronal Alignment?"

Background: Hindfoot coronal alignment is an important factor in the assessment of patients with many different foot and ankle complaints. A number of clinical and radiographic techniques have been described to measure hindfoot coronal alignment, but none of them are widely accepted. The purpose of the present study was to assess the correlation between clinical and radiographic hindfoot alignment measures and to evaluate the reproducibility of each. Methods: We evaluated 85 patients with foot and/or ankle symptoms. Hindfoot clinical alignment was measured from photographs. Each patient was placed at a distance of 1 m from the observer, with both feet placed parallel. Four photographs were taken, at a height of 40 cm: a posterior view of both lower limbs including knees, a posterior view focalized on the studied hindfoot, an anterior view of the foot, and the last view of the medial aspect of the foot. Radiographic alignment was quantified on long axial view radiographs. Patients were lying over the film cassette with a focus distance of 1 m and the beam pointed to the ankle joint. The inclination angle of the beam was 45 degrees to the floor. Measurements were independently made by 2 observers, who were asked to classify pictures into 3 categories: varus, neutral, and valgus. Radiographic measurements were made using the angle measurement tool on the radiograph viewer. The intraclass correlation coefficients (ICCs) and the 95% confidence interval (CI) of the ICC were used to quantify the inter- and intraobserver reliability for clinical assessment. Radiographic parameters were correlated by calculating the Pearson correlation coefficient (r). Results: The intraobserver ICC for clinical analysis was good for both observers, while the interobserver ICC was moderate for both measurements. Regarding radiographic assessment, there was significant intra- and interobserver reliability. The correlation between both methods was weak for both observers. Conclusions: We found only weak intra- and interobserver correlations between the clinical and radiographic assessment of hindfoot coronal alignment. It is therefore necessary to complement the clinical evaluation of hindfoot alignment with an objective measurement method such as a long axial view radiograph. Further studies comparing different measurement methods need to be performed to establish the most objective evaluation. Level of Evidence: Level III, diagnostic study.

Comparison of Visual Field Test Measurements With a Novel Approach on a Wearable Headset to Standard Automated Perimetry.

PRCIS: This study of inter-test comparability of a novel visual field application installed on an augmented-reality portable headset and Humphrey field analyzer Swedish interactive thresholding algorithm (SITA) Standard visual field test demonstrates the excellent correlation of mean deviation (MD) and mean sensitivity (MS). PURPOSE: To determine the correlation between visual field testing with novel software on a wearable headset versus standard automated perimetry. PATIENTS AND METHODS: Patients with and without visual field defects attributable to glaucoma had visual field testing in one eye of each patient with 2 methods: re:Imagine Strategy (Heru, Inc.) and the Humphrey field analyzer (Carl Zeiss Meditec, Inc.) SITA Standard 24-2 program. Main outcome measures included MS and MD, which were evaluated by linear regression, intraclass correlation coefficient (ICC), and Bland Altman analysis for assessment of the mean difference and limits of agreement. RESULTS: Measurements from 89 eyes of 89 patients (18 normal and 71 glaucomas) were compared with both instruments. Linear regression analysis demonstrated an excellent Pearson correlation coefficient of r = 0.94 for MS and r = 0.95 for MD. ICC analysis demonstrated high levels of concordance (ICC = 0.95, P < 0.001 for MS and ICC = 0.94, P < 0.001 for MD). Bland-Altman analysis determined a small mean difference between the two devices (Heru minus Humphrey) of 1.15 dB for MS and 1.06 dB for MD. CONCLUSIONS: The Heru visual field test correlated well with SITA Standard in a population of normal eyes and eyes with glaucoma.

The endoplasmic reticulum stress sensor IRE1 regulates collagen secretion through the enforcement of the proteostasis factor P4HB/PDIA1 contributing to liver damage and fibrosis.

Collagen is one the most abundant proteins and the main cargo of the secretory pathway, contributing to hepatic fibrosis and cirrhosis due to excessive deposition of extracellular matrix. Here we investigated the possible contribution of the unfolded protein response, the main adaptive pathway that monitors and adjusts the protein production capacity at the endoplasmic reticulum, to collagen biogenesis and liver disease. Genetic ablation of the ER stress sensor IRE1 reduced liver damage and diminished collagen deposition in models of liver fibrosis triggered by carbon tetrachloride (CCl 4 ) administration or by high fat diet. Proteomic and transcriptomic profiling identified the prolyl 4-hydroxylase (P4HB, also known as PDIA1), which is known to be critical for collagen maturation, as a major IRE1-induced gene. Cell culture studies demonstrated that IRE1 deficiency results in collagen retention at the ER and altered secretion, a phenotype rescued by P4HB overexpression. Taken together, our results collectively establish a role of the IRE1/P4HB axis in the regulation of collagen production and its significance in the pathogenesis of various disease states.

Auto-brewery syndrome A diagnostic challenge

Auto-brewery syndrome is defined as intestinal distillation syndrome and is probably caused by an overgrowth of microorganisms which metabolize carbohydrates to ethanol. In this report, we describe the case of a patient with classical symptoms of auto-brewery syndrome, with no prior alcohol ingestion and clinical improvement after medical treatment was instituted. It is a very rare case and, due to its inadequate description in the medical literature, we attempt to describe the essentials of the disease and the diagnostic challenge it represents.

El objetivo de este estudio fue analizar el empleo de la telemedicina como herramienta en pacientes con pie diabético, por parte de especialistas en pie y tobillo de la Argentina. Como objetivos secundarios se planteó valorar la satisfacción percibida por los profesionales con el uso de esta herramienta, evaluar qué estrategias se usaron para realizar la consulta médica remota y determinar la permanencia al retornar a la actividad asistencial habitual. Materiales y Métodos: Se enviaron tres encuestas a los socios de la Sociedad Argentina de Medicina y Cirugía de la Pierna y Pie, entre mayo 2020 y abril de 2022. Resultados: La función más valiosa de la consulta remota fue la prevención (75% de los encuestados), el seguimiento clínico (54,1%), el seguimiento posoperatorio (41,6%) y el diagnóstico (29,1%). El recurso más utilizado fue la conversación telefónica, seguida del envío de imágenes por mensajería instantánea. Solo el 37,5% utilizó las plataformas de historia clínica virtual. Conclusiones: Los recursos más utilizados para la consulta remota fueron la conversación telefónica, seguida del envío de imágenes por mensajería instantánea. El 33,4% estaba conforme con la consulta por telemedicina en mayo de 2020, mientras que, en julio, la conformidad ascendió al 46,7%. En abril de 2022, solo el 13% continuaba con las consultas remotas. Nivel de Evidencia: IV

Introduction: Telemedicine was the recommendation of international societies during the COVID-19 pandemic for medical consultations in patients with diabetic foot (DF). The main aim of this work is to evaluate the use of telemedicine as a tool for the eva-luation and follow-up of patients with DF by foot and ankle specialists in Argentina. As secondary objectives, we propose to assess the satisfaction perceived by the professionals with the use of this tool, to evaluate the specific strategies used to carry out the remote medical consultation, and to determine its permanence when returning to the usual care activity. Materials and Methods:Three surveys were sent to members of the Argentine Society of Medicine and Surgery of the Leg and Foot in May and July 2020 and April 2022. Results: According to 75% of respondents, the most valuable function of telemedicine was prevention, followed by monitoring of the clinical pathology (54.1%), postoperative follow-up (41.6%), and diagnosis (29.1%). The most commonly used resources for remote consultation were telephone conversations, followed by images sent by instant messaging. Only 37.5% used electronic health record platforms during 2020. Conclusions: The most commonly used resources for remote consultation were telephone conversations, followed by images sent by instant messaging. 33.4% of respondents were satisfied with telemedicine consultations in May 2020, while in July, satisfaction with this tool rose to 46.7%. In April 2022, only 13% of those surveyed in July 2020 continued offering remote consultations. Level of Evidence: IV

A Refined Minimally Invasive Distal First Metatarsal Osteotomy for Moderate Hallux Valgus Treatment: The BC Procedure.

During the last 2 decades, there was an increasing interest in mini-invasive procedures for hallux valgus correction. In this scenario the Bösch technique appears to be a reproducible distal metatarsal osteotomy (DMO) to achieve a proper correction. Our DMO variant, called BC, was planned to combine the stability and predictability of the chevron osteotomy, with the power of correction, low surgical time and mini-invasive approach of the Bösch-SERI technique. The purpose of this investigation is to describe the surgical technique and report the results of this modified procedure at a minimum 2-year follow-up. Sixty-three patients who underwent the BC technique for mild and moderate hallux valgus were prospectively evaluated. Mean follow-up was 36.5 (range 23.4-59.8) months, the mean American Orthopedic Foot and Ankle Society score improved from a median of 47.4 points preoperatively to a median of 88 points postoperatively (p < .05). First MTPJ ROM did not change from preoperative period (mean 32.5°) to the postoperative period (mean 31.8°) (p > .65). All osteotomies went on to bony healing in the 6-week follow-up visit. Fifty-two (82%) of patients were either very satisfied or satisfied with the procedure (p < .05). With our numbers, BC osteotomy is shown to be a technique that can treat both mild and moderate deformities, achieving correction that is maintained over the follow-up evaluated, with a 24 relatively simple procedure and short operative time.

Introduction. Intellectual disability is considered a global public health problem, the prevalence ranges from 1% to 3% of the world population, a figure whose genetic origin is estimated to be represented by 5-7% of subtelomeric syndromes. The objective of this research was to determine the frequency of intellectual disability of genetic etiology due to cryptic chromosomal rearrangements in 69 patients of IDAI. Material and methods. The descriptive cross-sectional study was carried out at the Institute of Genetics in 69 patients with intellectual disabilities from 5 to 18 years of age from the Institute for Child Adaptation (IDAI). The study was divided into three stages, the first consisted of preparing the genetic clinical history, then peripheral blood karyotyping was performed on all patients, finally, with suspected diagnosis, molecular cytogenetics was performed on nine of them, using a locus-specific probe. Results. 43.48% of chromosomal rearrangements were found, 24.67% corresponded to cryptic syndromes, of these 7.25% responded to subtelomeric syndromes. Greater involvement was observed in the male population: 45 men (65%) and 24 women (35%), obtaining a sex ratio of 1.88 in favor of the male sex. Conclusions. The genetic cause must be considered in all idiopathic intellectual disability, especially that due to cryptic chromosomal rearrangements. To confirm the diagnostic suspicion, classical cytogenetics and fluorescent in situ hybridization techniques are used, thus reaching a more precise diagnosis to assist in the genetic counseling of the patient.

Tumor de células granulares en región axilar: a propósito de un caso y revisión de la literatura / Tumor of granular cells in the axillar region: purpose of a case and literature review

Resumen El tumor de células granulares es una neoplasia infrecuente, de comportamiento biológico benigno. Por lo general, se presenta entre la cuarta y sexta década de vida como una lesión solitaria, de crecimiento lento y buen pronóstico. Su histogénesis es probablemente de origen neural siendo positivo para S-100 y Enolasa Neuronal Especifica. Se muestra un caso con una localización inusual en la región axilar, las dificultades para alcanzar el diagnóstico puesto que puede confundirse con otras neoplasias, y los elementos clínicos esenciales de este tipo de tumor.

Abstract Granular cell tumor is a rare neoplasm with benign behavior. It usually occurs in the fourth to sixth decade of life as a solitary, slow growing lesion with a good prognosis. Its histogenesis is probably of neural origin, being positive for S-100 and Neuron-Specific Enolase. We demonstrate an unusual location in the axillary region, the obstacles to reaching the diagnosis since it can be confused with other malignancies, and the essential elements for clinically suspecting benign lesions of this type.

SANDBLASTING INFLUENCE ON BOND STRENGTH OF CoCr ALLOY AND ONE ADHESIVE 10 MDP BASED / INFLUENCIA DEL ARENADO EN LA RESISTENCIA DE UNIÓN DE UNA ALEACIÓN DE CoCr Y UN ADHESIVO A BASE DE 10 MDP

Traditionally, fixed prostheses based on base metal alloys were retained on their abutments with powder-liquid cement (zinc phosphate, polycarboxylate, glass ionomer). Currently, with the development of CAD-CAM, there is a tendency to make conservative dental preparations. Undoubtedly it is a very good technique, concerning healthy dental tissue. But the resulting restorations would already need cement and adhesives that capable of chemically bonding to the different substrates, so as not to peel off. Manufacturers indicate that molecules such as 10 MDP, VBDATDT, 4-META can bind to metals. METHOD. 30 CoCr cylinders were divided into 3 groups. With the first, sandblasting was carried out and an adhesive agent based on 10 MDP was immediately placed to cement 4 resin microtubes using a resinous cement. The remaining groups were sandblasted in the same way, but in them, it was decided to wait for 24 and 48 hours to perform the adhesive procedure. RESULTS. The immediate group reached the highest values of bond strength. When more time was waited after sandblasting, the lowest values were obtained, even after aging. CONCLUSIONS. CoCr alloys can be cemented with resinous cement, as long as a correct mechanical and chemical surface treatment is carried out.

Tradicionalmente las prótesis fijas a base de aleaciones de metal base se retenían sobre sus pilares con cementos polvo-líquido (fosfato de zinc, policarboxilato, ionómero de vidrio). Actualmente con el desarrollo del CAD CAM, existe la tendencia a realizar preparaciones dentales conservadoras. Indudablemente es una muy buena técnica, por el respeto del tejido dental sano. Pero las restauraciones resultantes ya necesitarían de cementos y adhesivos que sean capaces de adherirse químicamente a los diferentes sustratos, para no despegarse. Fabricantes indican que, moléculas como el 10 MDP, el VBDATDT, 4-META pueden unirse a los metales. MÉTODO. 30 cilindros de CoCr fueron divididos en 3 grupos. Con el primero, se procedió a arenar e inmediatamente se colocó un agente adhesivo a base de 10 MDP para cementar 4 microtubos de resina por medio de un cemento resinoso. Con los grupos restantes de igual manera se arenó, pero en ellos se decidió esperar 24 y 48 horas para realizar el procedimiento adhesivo. RESULTADOS. El grupo inmediato alcanzó los mas altos valores de resistencia de unión. Cuando se esperó mas tiempo después de arenar se obtuvieron los más bajos valores, incluso después de envejecidos. CONCLUSIONES. Las aleaciones de CoCr pueden ser cementadas con cementos resinosos, siempre y cuando se realice un correcto tratamiento mecánico y químico de su superficie.

Correction Power of Percutaneous Adductor Tendon Release (PATR) for the Treatment of Hallux Valgus: A Cadaveric Study.

Osteotomies are commonly used in order to correct hallux valgus deformity. However, soft tissue structures also play an essential role in the etiology, progression, and treatment of hallux valgus (HV). The purpose of the present study was to analyze the correcting power (varus), reduction strength (sesamoid) and rotation of metatarsal and proximal phalanx after percutaneous adductor tendon release (PATR). To date, no study addresses this issue. Eleven cadaveric fresh-frozen below-the-knee cadaveric lower limbs with associated hallux valgus deformity were used. These specimens were subjected to a constant abduction force after PATR. HV and intermetatarsal angles showed statistically significant differences when comparing the preoperative and postoperative periods. PATR showed to be a reliable technique as the adductor tendon was completely released in 9 cases, and 75% released in the remaining 2 feet. The study supports that PATR provides powerful and quantifiable correction of HV deformity and can be accurately performed percutaneously.

Two-step Testing for Clostridioides Difficile is Inadequate in Differentiating Infection From Colonization in Children.

OBJECTIVES: Recent Infectious Disease Society of America guidelines recommend multistep testing algorithms to diagnose Clostridioides difficile infection (CDI), including a combination of nucleic acid amplification-based testing (NAAT) and toxin enzyme immunoassay (EIA). The use of these algorithms in children, including the ability to differentiate between C. difficile colonization and CDI, however, has not been evaluated. METHODS: We prospectively enrolled asymptomatic pediatric patients with cancer, cystic fibrosis (CF), or inflammatory bowel disease (IBD) and obtained a stool sample for NAAT testing. If positive by NAAT (colonized), EIA was performed. In addition, children with symptomatic CDI who tested positive by NAAT via the clinical laboratory were enrolled, and EIA was performed on residual stool. A functional cell cytotoxicity neutralization assay (CCNA) was also applied to stool samples from both the colonized and symptomatic cohorts. RESULTS: Of the 225 asymptomatic children enrolled in the study, 47 (21%) were colonized with C. difficile including 9/59 (15.5%) with cancer, 30/92 (32.6%) with CF, and 8/74 (10.8%) with IBD. An additional 41 children with symptomatic CDI were enrolled. When symptomatic and colonized children were compared, neither EIA positivity (44% vs 26%, P = 0.07) nor CCNA positivity (49% vs 45%, P = 0.70) differed significantly or were able to predict disease severity in the symptomatic cohort. CONCLUSIONS: Use of a multistep testing algorithm with NAAT followed by EIA failed to differentiate symptomatic CDI from asymptomatic colonization in our pediatric cohort. As multistep algorithms are moved into clinical care, the pediatric provider will need to be aware of their limitations.

Al ser potencialmente mortal, es vital la elaboración de estrategias preventivas basadas en los conocimientos y prácticas comunitarias. Objetivos: Identificar los conocimientos, actitudes y prácticas relacionados con la malaria y comparar con hallazgos de otras áreas endémicas. Métodos: Se realizó un estudio observacional, descriptivo y de corte transversal en la región de Maniapure del 28 al 31 de agosto del 2018. Se aplicó un cuestionario de 30 preguntas de respuestas cerradas. Los resultados fueron presentados según su frecuencia absoluta y relativa. Resultados: Se entrevistaron a 77 jefes de familia, de los cuales 63,64 % (n=49) refirió tener antecedente de malaria y 38,96 % (n=30) conoció a alguien que haya fallecido en su comunidad por esta. En cuanto a conocimientos, 79,22 % (n=61) sabe que la enfermedad se adquiere por la picadura de un mosquito, 51,95 % (n=40) cree que se transmite por el agua y 97,4 % (n=75) asocia la fiebre como síntoma principal. A nivel de actitudes y prácticas, el 92,21 % (n=71) acudiría al médico para tratar la enfermedad, 62,34 % (n=29) mantiene los canales y zanjas limpias y 70,13 % (n=54) usa mosquitero y/o repelente. Conclusión: El área de Maniapure se ubica en una región endémica, y al tratarse de poblaciones susceptibles con diferente trasfondo cultural, se deben elaborar planes educativos individualizados orientados a la prevención, y evaluar su impacto en la práctica.

Introduction: Malaria is a disease with public health significance, with an increase in the last years in Bolivar State. As a potentially life-threatening infection, the development of preventive strategies based on community knowledge and practices is necessary. Objectives: To identify the knowledge, attitudes, and practices related to malaria and compare it with findings from other endemic areas. Methods: An observational, descriptive, and cross-sectional study was conducted in the Maniapure region from August 28 to 31, 2018. A questionnaire of 30 questions with closed answers was applied. The results were presented according to their absolute and relative frequency. Results: 77 family leaders were interviewed, of which 63.64 % (n=49) reported having a history of malaria and 38.96 % (n=30) knew someone who had died in their community from it. About knowledge, 79.22 % (n=61) knew that the disease is acquired by a mosquito bite, 51.95 % (n=40) believed that it's transmitted through water, and 97.4 % (n=75) associate fever as the main symptom. In relation to attitudes and practices, 92.21 % (n=71) would go to the doctor to treat the disease, 62.34 % (n=29) kept the channels and ditches clean and 70.13 % (n= 54) used a mosquito net and/or repellent. Conclusion: Maniapure is located in an endemic region, and since they have susceptible population with different cultural backgrounds, individualized educational plans (focused on prevention) should be elaborated, as well as test the impact in practices.

Factores asociados con dolor severo en pacientes con fascitis plantar: Un análisis de relaciones / Factors associated with severe pain in patients with plantar fasciitis: An association analysis

Objetivo: Describir los factores asociados con niveles de dolor mas severo en una cohorte de pacientes con fascitis plantar. El objetivo secundario fue analizar cuales de estos factores estaban asociados con niveles mas altos de mejoria clinica luego del tratamiento conservador. Materiales y Métodos: Se evaluo a una cohorte prospectiva de pacientes con diagnostico de fascitis plantar. Cada participante completo una escala ordinal visual de dolor (del 1 al 10) para dolor del primer paso y dolor al final del dia y encuestas FFI-R (Foot Function Index-Revised). Tambien se realizo una evaluacion demografica. La dorsiflexion de la articulacion del tobillo, el rango de movilidad de la primera articulacion metatarsofalangica, la rigidez del gastrocnemio y el angulo popliteo tambien se evaluaron de manera estandar. Resultados: Se incluyo a 214 pacientes. El 64% eran hombres (118 pacientes), la media de la edad era de 49.67 anos (DE 13.16) y el indice de masa corporal promedio, de 28,53 (DE 5,18). En el analisis multivariado, se observo que el riesgo de un puntaje ≥8 en la escala de dolor aumento cuando el paciente refirio estar de pie por mas de 6 h (OR 1,17; p = 0,03; IC95% 1,02-1,35). El riesgo de un puntaje >8 fue mayor cuando el grado de dorsiflexion del tobillo fue <0° (OR 1,20; p = 0,03; IC95% 1,02-1,41). Conclusión: Nuestros hallazgos apoyan indirectamente la hipotesis de que la dorsiflexion limitada del tobillo juega un papel como factor de riesgo asociado a un puntaje ≥8 en la escala de dolor, en los casos de fascitis plantar. Nivel de Evidencia: IV

Objective: The main purpose of our study was to describe the factors associated with more severe pain levels in a cohort of patients with plantar fasciitis (PF). The secondary purpose of this study was to determine which of these factors were associated with higher levels of clinical improvement after conservative therapy. Materials and Methods: We conducted a prospective study in a cohort of patients with PF. Each participant completed an ordinal pain scale (1-10) for first-step pain and end-of-day pain, and Foot Function Index-Revised (FFI-R) surveys at enrollment. Also, patient demographics were evaluated. The ankle joint dorsiflexion, the range of motion (ROM) for the first metatarsophalangeal joint (MTPJ), the gastrocnemius tightness, and the popliteal angle were evaluated through standard tests. Results: Our study included 214 participants, of which 64% (118 patients) were males, the average age was 49.67 years (SD 13.16) and the average BMI was 28.53 (SD 5.18). The multivariate analysis showed that the risk of having a Visual Analog Scale (VAS) score ≥8 increased when the patient reported standing for more than 6 hours (OR=1.17; P=0.03; CI95%: 1.02-1.359). The risk of a >8-VAS score was higher when the level of ankle dorsiflexion was <0 (OR=1.20; P=0.03; CI95%: 1.02-1.41). Conclusion: Our findings indirectly support the hypothesis that limited ankle dorsiflexion ROM plays a role as a risk factor associated with VAS scores ≥8 in PF patients. Level of Evidence: IV

Youngswick osteotomy for treatment of moderate hallux rigidus: Thirteen years without arthrodesis.

PURPOSE: The purpose of this study was to evaluate the need for first metatarsophalangeal joint (MTPJ) arthrodesis as a measure of the Youngswick osteotomy survival, or any other secondary procedures in the long term follow up in patients with stage II and III hallux rigidus. METHODS: We retrospectively evaluated 61 patients with stage II and III hallux rigidus who had undergone Youngswick osteotomy and analyzed their outcomes in the long term using first metatarsophalangeal arthrodesis as an end point. The candidates for inclusion underwent clinical and radiographic evaluation, including the Foot and Ankle Outcome Score (FAOS). RESULTS: Mean follow-up time was 54.8 months. All patients had improved their FAOS, with all achieving postoperative scores >75 points at the final follow up (P<0.05). Although 49 % (P<0.05) of the patients depicted worsening of the radiological aspect of the MTPJ, over the long time, no patient needed a first MTPJ arthrodesis. CONCLUSION: Our results show satisfying long-term outcomes with regard to function, pain relief, and patient satisfaction of the Youngswick osteotomy in grade II as well as grade III hallux rigidus that sustained over the follow up period; even in patients followed up for over 13 years. LEVEL OF EVIDENCE: III.

Mucopolisacaridosis tipo VI: Reporte de tres casos y revisión de la literatura / Muchopolysaccharidosis VI: Report of three cases and literature review

El síndrome de Maroteaux-Lamy es una de las mucopolisacaridosis menos frecuente, con una incidencia aproximada de 0.36 a 1.30 por cada 100,000 nacidos vivos. Causado por una mutación en el gen ARSB, que produce la deficiencia enzimática de arilsulfatasa Bocasionando acumulación de dermatán sulfato en las células. Clínicamente, los pacientes presentan afectación multiorgánica progresiva. En este trabajo presentamos tres pacientes de origen boliviano no emparentados con MPS VI. Adicionalmente revisamos 38 casos de pacientes con MPS VI reportados en literatura.

Metatarsalgia: Assessment Algorithm and Decision Making.

Historically, metatarsalgia was approached as a forefoot condition, most often associated with hallux valgus. Consequently, surgical treatments were limited to that anatomic zone, disregarding more proximal structures. In order to assess this entity properly, it is necessary to consider anatomic and biomechanical factors, as well as general and local conditions of the affected patients. A thorough understanding of the multiple potential causal factors is essential to ensure selection of the optimal treatment.
