Pelvic limb reconstruction failed by propeller flap resolved with microsurgery

Reconstruction of lower limb defects is a constant challenge for surgeons, the etiology of the defect can be very variable from diabetic ulcers, traffic accidents, fall from height, oncological resections and many others. Free flaps have always been an important option because it has great results in complex reconstructions in lower limbs, it is a microvascular technique, so it has a higher level of complexity. This technique is usually reserved for extensive perilesional wide defects. On the other hand, the propeller flap, which is considered less invasive and easier as it does not involve microvascular surgery. An 18-year-old patient who had a fracture of the right tibial pylon due to a 7-meter drop, who after orthopedic treatment had a defect with exposure of ostesynthesis material of 3 cm in circumference in the medial malleolus. This defect was first managed with a propeller flap complicated with necrosis at 48 hours which was treated with sub atmospheric pressure system for 5 days and later with an ultra-thin anterolateral flap of the pelvic limb. Complete pedicled propeller flap failure is very rare but, because necrosis develops distally, even partial necrosis can expose bone, tendons, or other tissue. Some surgeons consider that propeller flap placement is risky in this location, especially the distal third of the lower leg a prefer to use free flaps. Whenever any pelvic member reconstruction plan fails in the distal third, the best and safest is the use of microsurgery even with the failure of a previous micro vascular flap

Diagnostic yield of early repeat colonoscopy after suboptimal bowel preparation in a fecal immunochemical test-based screening program

Background Current guidelines regarding surveillance after screening colonoscopy assume adequate bowel preparation. However, follow-up intervals after suboptimal cleansing are highly heterogeneous. We aimed to determine the diagnostic yield of early repeat colonoscopy in patients with suboptimal bowel preparation in fecal immunochemical test (FIT)-based screening colonoscopy. Methods An observational study including patients who underwent colonoscopy with suboptimal bowel preparation after positive FIT screening and then repeat colonoscopy within 1 year. Suboptimal preparation was defined as a Boston Bowel Preparation Scale (BBPS) score of 1 in any segment. Patients with a BBPS score of 0 in any segment or incomplete examination were excluded. The adenoma detection rate (ADR), advanced ADR (AADR), and colorectal cancer rate were calculated for the index and repeat colonoscopies. Results Of the 2474 patients with FIT-positive colonoscopy at our center during this period, 314 (12.7%) had suboptimal preparation. Of the 259 (82.5%) patients who underwent repeat colonoscopy, suboptimal cleansing persisted in 22 (9 %). On repeat colonoscopy, the ADR was 38.7% (95% CI 32.6% to 44.8%) and the AADR was 14.9% (95%CI 10.5% to 19.4%). The per-adenoma miss rate was 27.7% (95 %CI 24.0% to 31.6%), and the per-advanced adenoma miss rate was 17.6% (95%CI 13.3% to 22.7%). After repeat colonoscopy, the post-polypectomy surveillance recommendation changed from 10 to 3 years in 14.7% of the patients with previous 10-year surveillance recommendation. Conclusions Patients with suboptimal bowel preparation on FIT-positive colonoscopy present a high rate of advanced adenomas in repeat colonoscopy, with major changes in post-polypectomy surveillance recommendations

Microsurgery in complex trauma of pelvic limb in a pediatric patient: case report

Complex trauma is defined as the condition secondary to the exchange of kinetic energy of two or more tissues in one limb. This entity is a surgical emergency that can have many sequelae and can even result in limb loss. An 11-year-old female patient presents complex pelvic limb trauma secondary to contuse injury caused by a helicopter’s rotor blades.  Pelvic limb reconstruction was performed with iliac crest bone graft, the fracture was stabilized with an external fixator and the skin defect was covered with an anterolateral microvascular thigh flap (ALT). There was an adequate integration of the bone graft with adequate skin coverage thanks to the ALT thigh flap. The patient presented discreet limb shortening as consequence.  Currently, microsurgery is the only medical option that meets the objectives of limb reconstruction. Microsurgical techniques can be used in pediatric and adult patients. The success of any recovery from complex trauma is vigorous surgical cleaning, avoiding sequential and/or multiple washes

Metabolic syndrome, adiposity, diet, and emotional eating are associated with oxidative stress in adolescents

Background: Metabolic syndrome (MS), a condition related to adiposity and oxidative stress, can develop in adolescence, a critical stage in life that impacts health in adulthood. However, there is scarce scientific research about the relationship between lifestyle factors, emotion management, and oxidative stress in this phase of life.Aim: To analyze whether nutritional parameters, lifestyle factors, emotion management, and MS in adolescents are associated with oxidative stress measured by the biomarker 8-isoprostane.Methods: A cross-sectional study was carried out in 132 adolescents (48.5% girls, aged 12 ± 0.48 years) and data were collected on nutritional parameters (anthropometric measurements, biochemical analyzes, and blood pressure), lifestyle factors (physical activity, sleep, and diet), and emotion management (self-esteem, emotional eating, and mood). 8-isoprostane was analyzed in spot urine samples. The study population was categorized in three groups (healthy, at-risk, and with MS) using the International Diabetes Federation definition of MS in adolescents. To capture more complex interactions, a multiple linear regression was used to analyze the association between 8-isoprostane and the aforementioned variables.Results: Urinary 8-isoprostane levels were significantly higher in the MS group compared to the healthy group (1,280 ± 543 pg./mg vs. 950 ± 416 pg./mg respectively). In addition, univariable analysis revealed positive significant associations between 8-isoprostane and body mass index, waist circumference, waist-to-height ratio, body fat percentage, blood lipid profile and glucose, emotional eating, and refined cereal intake. Conversely, a negative significant association was found between 8-isoprostane and sleep duration and fish intake. The multiple linear regression analysis revealed associations between 8-isoprostane and LDL-c (β = 0.173 value of p = 0.049), emotional eating (low β = 0.443, value of p = 0.036; high β = 0.152, value of p = 0.470), refined cereal intake (β =0.191, value of p = 0.024), and fish intake (β = -0.187, value of p = 0.050).Conclusion: The MS group, LDL-c, emotional eating, and high refined cereals and low fish intakes were associated with higher levels of oxidative stress in an adolescent population.</p

Genetic diversity of HLA system in four populations from Baja California, Mexico: Mexicali, La Paz, Tijuana and rural Baja California

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 250 Mexicans from the states of Baja California Norte and Baja California Sur living in Mexicali (N = 100), La Paz (N = 75), Tijuana (N = 25) and rural communities (N = 50) to obtain information regarding allelic and haplotypic frequencies. The most frequent haplotypes for the Baja California region include nine Native American and five European haplotypes. Admixture estimates revealed that the main genetic components are European (50.45 ± 1.84% by ML; 42.03% of European haplotypes) and Native American (43.72 ± 2.36% by ML; 40.24% of Native American haplotypes), while the African genetic component was less apparent (5.83 ± 0.98% by ML; 9.36% of African haplotypes)

Practical guideline for Benign paroxismal positional vertigo

Introduction and objective: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vertigo, characterized by brief attacks of rotatory vertigo associated with nystagmus, which are elicited by specific changes in head position relative to gravity. The observation of positional nystagmus is essential for the diagnosis of BPPV. The treatment consists in maneuvers of canalith repositioning procedure to move otoconial debris from the affected semicircular canal to the utricle. These guidelines are intended for all who treat the BPPV in their work, with an intention to assist in the diagnosis and application of an appropriate therapeutic method. Method: The experience and analysis of different national and international consensus on BPPV, has allowed to a large group of ENT specialists of the Communities of Castilla y León, Cantabria and La Rioja (Spain), carry out this guide. Results: The different clinical entities are reviewed. BPPV of the posterior semicircular canal, horizontal canal and anterior canal, BPPV affecting several canals, atypical and central BPPV, subjective BPPV and the characteristics of this process in the elderly. Canalith repositioning procedures have been illustrated with explanatory drawings. Discussion and conclusions: Although the pathophysiology of BPPV is canalolithiasis comprising free-floating otoconial debris within the endolymph of a semicircular canal, or cupulolithiasis comprising otoconial debris adherent to the cupula, there are still many issues to be resolved. We think that the best way to find answers is part of using a common methodology in the diagnosis and treatment of these patients.Introducción y Objetivo: El vértigo periférico más frecuente es el Vértigo Posicional Paroxístico Benigno (VPPB), caracterizado por bruscos ataques de sensación rotatoria, que aparecen como consecuencia de determinados cambios en la posición de la cabeza con relación a la gravedad. La observación del nistagmo posicional es fundamental para el diagnóstico de VPPB. El tratamiento consiste en aplicar maniobras de reposición, para intentar trasladar los restos otoconiales libres, desde el conducto semicircular (CS) afectado hasta el utrículo. Esta guía, está orientada para quienes tratan el VPPB, con la intención práctica de ayudarles en el diagnóstico y tratamiento de esta enfermedad. Método: La experiencia y el análisis de diferentes acuerdos nacionales e internacionales sobre el VPPB, han permitido a un amplio grupo de especialistas ORL de las Comunidades de Castilla y León, Cantabria y La Rioja (España), llevar a cabo esta guía. Resultados: Se revisan las diferentes entidades clínicas. VPPB del conducto semicircular posterior (CSP), horizontal (CSA) y anterior (CSA), incluyéndose también el VPPB multicanal, VPPB atípico y central, VPPB subjetivo y las características de este proceso en el anciano. Las maniobras de reposición se han ilustrado con dibujos explicativos. Discusión y conclusiones: Aunque la fisiopatología del VPPB se explica por la presencia de restos otoconiales libres en la endolinfa de uno o varios conductos semicirculares (canalitiasis) y en algunos casos por su adherencia a la cúpula del CS (cupulolitiasis), aún quedan muchas cuestiones por resolver. Pero creemos que la mejor manera de encontrar respuestas parte de utilizar una metodología común en el diagnóstico y tratamiento de estos pacientes
