Prevention of motor ascending branch of the rectus femoris injuries in Bernese periacetabular osteotomy: a cadaveric study.

The Bernese periacetabular osteotomy (PAO) is a surgical procedure used to treat hip dysplasia in young adults, but it carries the risk of neurological complications, including injury to the motor ascending branch of the rectus femoris (MABRF). This study aimed to describe anatomical considerations to prevent MABRF injuries during PAO. A cadaveric study was conducted on seven specimens. The original and modified PAO approaches were used, with and without disinsertion of the rectus femoris muscle origin. The femoral nerve was dissected in all specimens from the endopelvic position to the MABRF origin (T-point). The average distance from the anterosuperior iliac spine to the T-point was 10.2 ± 0.4 cm. To protect the MABRF, a safety zone was identified for the osteotome placement during the ischial cut. The osteotome was slid over the joint capsule, deflecting the iliocapsularis muscle medially and distally. This manoeuvre shields the MABRF with the iliocapsularis muscle, reducing the risk of neurological injury. Both the original and modified PAO approaches were considered safe techniques with low risk to the rectus femoris innervation. These findings offer valuable insights for surgeons performing PAO, emphasizing the significance of understanding anatomical relationships and implementing protective measures to enhance patient outcomes and minimize complications. In conclusion, implementing these anatomical considerations can help prevent MABRF injuries during PAO, contributing to safer and more successful surgical interventions for hip dysplasia in young adults.

First report of a carbapenemase OXA-48-producing Hafnia alvei clinical isolate.

Introduction: Carbapenems are usually used in the treatment of infections caused by cephalosporin-resistant Enterobacterales ; however, the increase in carbapenem-resistant Enterobacterales (CRE) has become one of the most important problems in public health. Hafnia alvei is associated with intestinal and extraintestinal infections, especially in patients with any chronic disease or some type of immunosupression. H. alvei is resistant to first-generation aminopenicillins and cephalosporins owing to the ß-lactamase (Amp C) in their chromosome; the only carbapenem-resistant Hafnia strain described until now was due to a lack of the OmpK36 protein that plays an important role in permeability to carbapenems. Case presentation: We present the case of a 65-year-old male diagnosed with acute lithiasic cholecystitis. Culture of the biliary prosthesis yielded a OXA-48-producing H. alvei that was identified by MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) MS. Carbapenemase production was detected by immunochromatography and confirmed by sequencing. Conclusion: To our knowledge, this is the first report of OXA-48-producing H. alvei probably obtained by horizontal transfer from Enterobacter cloacae OXA-48 isolated in previous samples.

Clinical outcomes and complications following percutaneous closure of patent foramen ovale

Introduction: patent foramen ovale (PFO) has been associated with systemic embolic events, and evidence in favor of its closure is increasing. Our objective is to describe the main clinical outcomes and complications of percutaneous closure of patent foramen ovale. Materials and methods: patients who underwent percutaneous PFO closure from January 1, 2016, through September 1, 2021, were recorded retrospectively. Immediate outcomes (<72 hours), and early and late-onset clinical outcomes were evaluated. In-hospital and follow-up mortality were evaluated through medical chart reviews or telephone calls. Results: forty patients who underwent percutaneous PFO closure were included. There was a mean follow up of 2.3 years, the mean age was 43 ± 13.6 years, 7% were over 60 years old, 72.5% were women, 25% were hypertensive, 20% had diabetes, and 10% had a history of migraines. The mean RoPE score was 6, and 50% had a score greater than 7. Out of all the cases, three (7.5%) had serious adverse events and four had immediate complications. During follow-up, 2.5% had early-onset events consisting of atrial fibrillation and 2.5% had late-onset events due to CVA recurrence. There were no deaths from neurological causes and we reported a 100% survival. Discussion: From our experience, we highlight a low percentage of serious adverse events, and a low number of immediate, early and late-onset events, with a 100% survival, showing excellent results for percutaneous PFO closure.

Bernese Periacetabular Osteotomy: A Comparative Study of Four Types of Incisions.

Bernese periacetabular osteotomy has diverse complications associated with incisions, such as dehiscence, hypertrophy, depression, and hyperpigmentation on scars, which affect patient satisfaction. The objective was to evaluate aesthetics and satisfaction outcomes in four different incisions. We evaluated 176 incisions in 148 patients. The incisions performed were the original modified (16, group I), straight and shortened, (64, group II), "Z" shaped (16, group III), and oblique inguinal (48, group IV). The scars were evaluated for width and length, development of a hypertrophic scar, depression or hyperpigmentation, and dehiscence and resuture. A scale of satisfaction was applied (points ranging from 1 to 10). The Bartlett test and Kruskal-Wallis test were used. The mean width and length of the scars were 20.3 and 6.8 cm for group I, 6.5 and 8.1 for group II, 12.1 and 7.1 cm for group III, 13 and 1.4 cm for group IV, respectively. Hypertrophic scars were found in 18% in group I, 12.5% in group II, and 31.2% in group III. Depressed scars were found in 10.8% in group I and 7.1% in group II. Hyperpigmentation was found in 16% in groups I and II, 37% in group III, and 2% in group IV. Dehiscence was found in 8.1% in group I and 8.9% in group II. Satisfaction for group IV was nine points. The difference in length and width and satisfaction were statistically significant (P < 0.05). The oblique inguinal incision (group IV) showed a smaller percentage of complications, with an adequate aesthetic result, and a high grade of patient's satisfaction.

ABSTRACT The purpose of this article is to present a proposal for the measurement of human capital that integrates the components, variables and indicators determined from the research carried out around the measurement of human capital of a group of Colombian companies. To this end, a quantitative research was carried out under the design of case studies, in which the information was collected through the use of a survey applied to a statistically representative sample of employees at the strategic, tactical and operational levels, and through the review of documents and human resources information systems of the studied companies. In addition, a comprehensive review of the specialized literature on the subject of human capital was carried out in the Scopus, Science Direct, Dialnet, Redalyc and Google Scholar databases. The results show that the investigated companies are unaware of the elements that integrates human capital and do not have the traceability of the data of their personnel to measure it. It is concluded that the measurement of human capital should be examined starting from four components: knowledge, shared values, labor competencies and typology of personnel, based on which a proposal was built that incorporates, for each one of them, a set of variables and indicators to identify and quantify this intangible asset and increase the identification. of its management.

Bernese periacetabular osteotomy: functional outcomes in patients with untreated intra-articular lesions.

Developmental dysplasia of the hip (DDH) has been recognized to be a condition leading to osteoarthritis. Periacetabular osteotomy (PAO) has showed good results on hip preservation treatment for these cases. Nevertheless, intra-articular damage may be responsible for persistent post-operative symptoms, so treat the articular damage before or during the PAO has emerged as an alternative to address it. The objective is to identify the prevalence of intra-articular damage, functional outcomes of patients undergoing PAO with untreated intra-articular lesions and the survivorship free total hip arthroplasty (THA) at long-term follow-up. A retrospective review of 103 hips in 92 patients, mean age 26 years old (19-31), 96% females. Mean follow-up 7 years (range: 3-16). Intra-articular damage was evaluated with high-resolution magnetic resonance imaging (MRI) previous to perform the PAO, the chondral damage was evaluated using International Cartilage Repair Society classification. Harris Hip Score (HHS) was obtained in all patients. One hundred per cent of the cases had labral tears on MRI, hypertrophic labrum in 80.8% and paralabral cysts in 20.8%. Acetabular chondral damage was Grade 2 in 88.5% of the hips. HHS was good and excellent in 94%. Survivorship free of THA at 15 years was 87%. Chondrolabral damage is a common finding in patients with DDH. Despite that, excellent results are obtained with PAO without labral repair. We think the focus should be in the biomechanical and anatomical correction of the hip in patients with DDH.
