ABSTRACT

The rapid advancement of electronic devices and fabrication technologies has further promoted the field of wearables and smart textiles. However, most of the current efforts in textile electronics focus on a single modality and cover a small area. Here, we have developed a tailored, electronic textile conformable suit (E-TeCS) to perform large-scale, multimodal physiological (temperature, heart rate, and respiration) sensing in vivo. This platform can be customized for various forms, sizes and functions using standard, accessible and high-throughput textile manufacturing and garment patterning techniques. Similar to a compression shirt, the soft and stretchable nature of the tailored E-TeCS allows intimate contact between electronics and the skin with a pressure value of around ~25 mmHg, allowing for physical comfort and improved precision of sensor readings on skin. The E-TeCS can detect skin temperature with an accuracy of 0.1 °C and a precision of 0.01 °C, as well as heart rate and respiration with a precision of 0.0012 m/s2 through mechano-acoustic inertial sensing. The knit textile electronics can be stretched up to 30% under 1000 cycles of stretching without significant degradation in mechanical and electrical performance. Experimental and theoretical investigations are conducted for each sensor modality along with performing the robustness of sensor-interconnects, washability, and breathability of the suit. Collective results suggest that our E-TeCS can simultaneously and wirelessly monitor 30 skin temperature nodes across the human body over an area of 1500 cm2, during seismocardiac events and respiration, as well as physical activity through inertial dynamics.

ABSTRACT

Resumen: Introducción: El aneurisma de la arteria testicular es poco frecuente; el término se describe como la dilatación de cualquier vaso sanguíneo en el cuerpo. Caso clínico: Se presenta el caso de un paciente de 15 años con un aneurisma de la arteria testicular izquierda sin ningún antecedente de importancia familiar ni personal, quien se presentó a consulta por aumento de volumen en la región inguinal de larga evolución, acompañado de dolor esporádico y sin más síntomas. Se diagnosticó hernia inguinal y se procedió a cirugía. El diagnóstico se realizó de manera posoperatoria por medio de estudio histopatológico. En este caso, se destaca la presentación de un aneurisma verdadero de la arteria testicular y el resultado después del tratamiento quirúrgico definitivo. Conclusiones: La etiología del aneurisma y del pseudoaneurisma reportada en la literatura se describe posterior a un traumatismo testicular, y en pocos casos de origen congénito. Las manifestaciones clínicas pueden ser dolor y una masa inguinal, y muchas de las veces pueden confundirse con hernias inguinales o ser una patología agregada, por lo que el abordaje de los pacientes con patología inguinal o testicular debe ser protocolizado e incluir el aneurisma dentro de los diagnósticos diferenciales.


Abstract: Background: Aneurysm of the testicular artery is a rare entity; the term is described as the dilation of any blood vessel in the body. Case report: An 18-year-old patient with a left testicular artery aneurysm, with no family or personal history of medical importance, presented for consultation due to a volume increase of long evolution in the inguinal region, accompanied by sporadic pain with no other symptoms. The testicular artery aneurysm was not detectable preoperatively by ultrasound, which only reported data compatible with left inguinal hernia and varicocele. The diagnosis was made postoperatively by a histopathological study. This case highlights the presentation of a true aneurysm of the testicular artery and the result after definitive surgical treatment. Conclusions: The etiology of the aneurysm and pseudoaneurysm reported in the literature is described after a testicular trauma and, a few cases of congenital origin. The clinical manifestations are pain and an inguinal mass, which can be frequently confused with inguinal hernias or an aggregated pathology. Therefore, the approach of patients with inguinal or testicular pathology should be protocolized and include aneurysm within the differential diagnoses.

ABSTRACT

Ten cleft lip and palate patients with complete unilateral (five patients) and bilateral (five patients) clefts were treated by a multidisciplinary team integrated by psychologists, surgeons, orthodontists, prosthodontists, pediatric dentists, and speech pathologists, to obtain ideal soft tissue and hard tissue continuity, facial symmetry, functional and esthetic dentitions, excellent nasal architecture, subtle, and hidden lip scars. No hypernasality and adequate social adaptation were found in the 30 years follow-up (20-30 years follow-up with an average of 25.5 years). The patients were treated in a pro-active fashion avoiding complications and related problems, executing the ideal surgical, dental, and speech therapy plan, based on a close follow-up over the entire period. Those patients treated at the right time required less surgeries and less salvaging maneuvers and presented complete dentitions with less dental prosthesis or dental implants and stable occlusions, than those who missed the ideal dental and surgical treatment opportunities. The focus of this article is the need of a close long-term follow-up to ensure an ideal patient's quality of life.

ABSTRACT

Introdução: os protocolos para a reabilitação de implantes zigomáticos com próteses fixas não permitem a carga imediata dos implantes até culminar todo o período de osseointegração dos implantes convencionais anteriores. Dado este problema, propôs-se o protocolo pentagonal que oferece uma excelente estabilidade primária e permite a carga imediata. Objetivo: identificar as vantagens e as desvantagens da colocação do quinto implante zigomático no âmbito do desenho pentagonal, com o carregamento imediato da prótese provisória e a prótese definitiva no prazo de 60 dias após a cirurgia, a fim de avaliar os resultados. Material e Métodos: 85 implantes zigomáticos foram colocados em 17 pacientes (12 mulheres, cinco homens) com idades entre 11 e 66 anos (com média de 54,5 anos), com atrofia óssea severa maxilar com o desenho pentagonal de implantes zigomáticos com carga imediata. Para testar a estabilidade, a passividade, o estado e a manutenção da prótese pelo paciente, foram efetuados controles pós-operatórios na primeira semana, no primeiro mês e a cada três meses (seis a 34 meses), com uma média de 20,59 meses. Resultados: o implante zigomático anterior permite a carga imediata da prótese provisória no dia da cirurgia e da prótese final no prazo de 60 dias depois da cirurgia, em adição a isto, biomecanicamente reduz o braço da alavanca e o cantiléver. Conclusão: o desenho zigomático pentagonal oferece uma ancoragem alternativa na maxila atrófica que permite a carga imediata sem esperar pela osseointegração convencional e, portanto, reduz o tempo de tratamento, resultando em maior estabilidade, melhor distribuição de forças, menor taxa de complicações protéticas e maior êxito a longo prazo.


Introduction: the actual zygoma fixtures protocols for maxillary dental rehabilitation do not allow immediate loading, since the regular implants require the osseointegration period. The quadrangular design often presents an anterior cantilever, needing additional anterior fixtures. Biomechanically, an extra anterior immediately loadable implant would be the solution. Purpose: to point out the advantages and disadvantages of the fifth zygoma implant placement under the pentagonal design with immediate loading and the final prosthesis installed within 60 days after surgery and evaluate the results. Materials and methods: 85 zygoma fixtures were placed with pentagonal design and immediate loading on 17 patients (12 females, 5 males) ages between 11 and 66 years old (average 54.5 y.o.) with severe maxillary atrophy. To evaluate stability, passivity, condition and maintenance capacity of the prosthesis by the patient, follow ups were made the first week, the first month and every three months (6-34 months) with an average of 20.59 months. Results: the anterior zygoma fixture allows immediate loading of the provisional prosthesis the day of the procedure and installation of the final prosthesis within 60 days after surgery, in addition, biomechanically reduces the lever arm and the cantilever. Conclusions: the pentagonal zygoma design offers an alternative anchorage on the atrophic maxilla, allowing immediate loading, eliminating the osseointegration waiting period, therefore the treatment time shortens with excellent stability, better forces distribution, less prosthetic complications and greater success rates in the long term follow-up.

ABSTRACT

PURPOSE: This study evaluated the functional and cosmetic results of mandibular basal osteotomy, introducing new indications and fixation alternatives. MATERIALS AND METHODS: Ten patients 19 to 46 years old (mean, 32.3 years) were treated by orthognathic surgery, including mandibular basal osteotomy for correction of deficiency, excess, or asymmetry of the inferior mandibular border. An intraoral approach based on 3 incisions to the anterior and posterior mandible was used to maintain and protect soft tissues surrounding the mental nerve. After marking the bone inferior to the nerve, a reciprocal saw completed the osteotomy design and individual rigid fixation according to movement was executed. All patients were 3-dimensionally treated and the evaluation included clinical, radiographic, and photographic analysis pre and postoperatively; all patients were followed for a minimum of 12 months. RESULTS: All patients showed excellent functional and cosmetic results. Nine patients (9/10) were treated for advancement of the inferior border (mean, 6.89 ± 2.57 mm; P < .05). One of them underwent simultaneous inferior (3 mm) and lateral (4 mm) repositioning and 3 had combined lateral movement (mean, 3.5 ± 0.58 mm; P < .05). One patient (1/10) required posterior (4 mm) and inferior (5 mm) repositioning of the basal segment. CONCLUSIONS: Mandibular basal osteotomy is an innovative technique that is strongly predictable for correction of deficiency, excess, and/or asymmetry of the inferior mandibular border, decreasing morbidity and many other complications of traditional bone grafts and alloplastic techniques.

ABSTRACT

La actinomicosis cervicofacial es una enfermedad bacteriana crónica comúnmente causada por el Actinomyces Israelii, una bacteria anaeróbica gram positiva. Este organismo saprófito es una habitante normal de la cavidad bucal. La infección aparece generalmente después de un trauma, cirugía o una infección previa. La extracción del diente, la cirugía periodontal e infecciones orales son predisponentes al desarrollo de esta condición. La actinomicosis se presenta típicamente como una inflamación del maxilar inferior que puede simular un absceso. La lesión es indurada, fría al tacto y el pus que drena puede contener gránulos amarillos pequeños conocidos como "gránulos de azufre", sin un olor fétido. Este lesión tiende a recurrir generalmente. El objetivo de este estudio clínico fue probar el efecto de la clindamicina por vía oral en el tratamiento de la actinomicosis cervicofacial. Seis pacientes que presentaron actinomicosis cervicofacial fueron tratados con 1 gragea de 300 mg de clindamicina cada 6 horas por 21 días y eliminación quirúrgica de la etiología dental. Los pacientes fueron controlados por 6 meses después del tratamiento. La inflamación del maxilar inferior desapareció rápidamente, aproximadamente cuatro días después de tomar este antibiótico, el edema fue disminuyendo progresivamente. No hubo reaparición de la lesión después del tratamiento. La clindamicina oral es un antibiótico efectivo en infecciones anaeróbicas. Este antibiótico es una alternativa viable para el tratamiento eficaz de la actinomicosis cervicofacial. En nuestro estudio, no hubo recidiva
