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.

Comparative study on the impact of equally stressful environmental sporulation conditions on thermal inactivation kinetics of B. subtilis spores.

Control of bacterial spores continues to be one of the main challenges for the food industry due to their wide dissemination and extremely high resistance to processing methods. Furthermore, the large variability in heat resistance in spores that contaminate foods makes it difficult to establish general processing conditions. Such heterogeneity not only derives from inherent differences among species and strains, but also from differences in sporulation environments that are generally ignored in spores encountered in foods.

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.

Creating and Validating the DESEA Questionnaire for Men and Women.

In clinical practice, it is essential to be able to identify hypoactive sexual desire disorder (HSDD), with its different severity levels and assess the influence the subject's relationship has on the issue. In order to do this, questionnaires are needed that comprise appropriate psychometric properties. We analyzed the psychometric properties and factorial structure of the Sexual Desire and Aversion (DESEA) questionnaire that evaluates sexual desire and interpersonal stress (relationship problems) in male and female couples.

[Validation of the Spanish version of the Golombok Rust Inventory of Sexual Satisfaction].

Introduction: Self-reports are one of the most used techniques in the evaluation of human sexuality. For this reason, valid and reliable evaluation instruments are necessary for high quality studies.

Objective: The main purpose of this study was to translate and validate the Golombok Rust Inventory of Sexual Satisfaction for use in Spanish.

[Guide for the classification of clinical research articles for the International Journal of Andrology].

The classification of knowledge is essential for understanding between researchers and the advancement of science. In this article a brief classification of clinical research methods is presented. The advantages that researchers use the same nomenclature are recalled, which enables improved communication among researchers, facilitates replication of studies and searches in databases, and helps to establish the aspects that can affect the different research models.

[Effects of drug use and anxiety on premature ejaculation in a sample of Spanish drug addicts].

Introduction: Premature ejaculation may be due to many factors and one of them may be drug use.

Aims: The main objective of this study is to show how drug abuse affects the ejaculatory response, keeping in mind the different substances consumed, the level of anxiety and the period of withdrawal.

Method: Two samples were used, one for men who were addicted to drugs (N=925) and one of non-consumers (N=82).

Symptomatic medial exostosis of the great toe distal phalanx: a complication due to over-correction following akin osteotomy for hallux valgus repair.

Unlabelled: The authors present the case of a 54-year-old female who developed a painful compression lesion localized to the medial aspect of the base of the distal phalanx of the great toe as a complication of hallux valgus surgery. Preoperative radiographic evaluation of the patient's foot revealed the first ray to be longer than the second, a 12 degrees first intermetatarsal angle, a 33 degrees hallux abductus angle, and an exostosis at the medial aspect of the base of the hallux that was not considered by the surgeon to be important. Correction of the hallux valgus deformity was performed with a combination of scarf and Akin osteotomies, and the intermetatarsal and hallux abductus angles reduced to 2 degrees and 8 degrees , respectively.

Catastrophic wear in a metal-on-ceramic total hip arthroplasty.

A 51-year-old woman came to our clinic 6 months after a right total hip arthroplasty. She had noticed a slowly growing mass in the proximal thigh and referred progressive pain in the right groin. Plain radiography revealed premature acetabular cup aseptic loosening, and in the computed tomography study, a 14-cm-diameter mass was observed.

Metal levels in corrosion of spinal implants.

Corrosion affects spinal instrumentations and may cause local and systemic complications. Diagnosis of corrosion is difficult, and nowadays it is performed almost exclusively by the examination of retrieved instrumentations. We conducted this study to determine whether it is possible to detect corrosion by measuring metal levels on patients with posterior instrumented spinal fusion.

Corrosion and late infection causing delayed paraparesis after spinal instrumentation.

A 28-year-old female patient came to our hospital 14 years after surgical correction of adolescent idiopathic scoliosis with a 316L stainless-steel instrumentation. She presented progressive paraparesis during the last 2 months. Plain radiography, computed tomography scan and computed tomography-scan-guided needle biopsy revealed that a metallotic mass penetrated into the spinal canal, causing compression of the spinal cord at the T5-T6 level.

Retention of Cd, Zn and Co on hydroxyapatite filters.

This study qualifies and quantifies the immobilization of Cd, Zn and Co, (used as models of bivalent metal ions due to their relevant toxicity) in filters of synthetic hydroxyapatite (HAP) [Ca5(PO4)3OH]. They were flushed with solutions containing Cd (1 x 10(-5)M), Zn and Co (1 x 10(-4)M) at constant pH (8.6) and ionic strength (0.
