    ABSTRACT: Background: We used finite element analysis to study the mechanical displacements at three planes of the second through fourth hammertoes during the push-off phase of gait using a new neutral or 108 angled memory alloy intramedullary implant (FDA K070598) used for proximal interphalangeal joint arthrodesis. Methods: After geometric reconstruction of the foot skeleton from computed tomographic images of a 36-year-old man, an intramedullary implant was positioned in the virtual model at the neutral and 10 degrees angled positions at the proximal interphalangeal joints of the second through fourth hammertoes during the push-off phase of gait. The obtained displacement results in three planes were compared with those derived from the nonsurgical foot model using finite element analysis. Results: These results support the successful use of either a neutral or angled implant for proximal interphalangeal joint arthrodesis, with the neutral implant yielding slightly better results. Conclusions: The neutral implant reduced vertical displacement to a greater extent than did the angled implant. We also highlight the potential risk of iatrogenic curly toe when performing a proximal interphalangeal joint arthrodesis using an angled implant specifically at the fourth toe.

    ABSTRACT: The present study was undertaken to examine the positions of Spanish health professionals on a variety of bioethical issues and to determine the relationships between these positions and the professionals’ religious beliefs and political views. The study sample consisted of 50 individuals randomly selected from a database of Spanish health professionals who had received solid training in bioethics. A structured questionnaire was designed that contained six closed questions on positions on biomedical advances and science and biotechnology (eugenics, use of nonimplanted embryos for experimental purposes, human cloning, and the idea that science should have limits) and the respondents’ sociopolitical and religious views, and assessment scales were developed for the responses. The distribution of the responses was subjected to statistical analysis using analysis of variance (ANOVA). For the items with responses scored on a Likert scale, the positions taken were moderately adverse, and the vast majority of respondents believed that there should be limits to science. Religious convictions had greater influence on the responses than political orientation. There was evidence that liberal beliefs corresponded with what the authors consider to be more progressive ideas about the bioethics issues addressed in the study. The important questions of bioethics require an interdisciplinary approach and a combination of state and private-sector action to strengthen the links between religion and science, keep general knowledge up to date, and properly train biotechnology professionals. © 2015, Organizacion Panamericana de la Salud.

    ABSTRACT: Hallux Valgus (HV) is a highly prevalent forefoot deformity in older people associated with progressive subluxation and osteoarthritis of the first metatarsophalangeal (MTP) joint and it is believed to be associated with varying degrees of HV effect on the quality of life related to foot health. The aim of this study is to compare the impact of varying degrees of HV on foot health in a sample of older people. The sample consisted of 115 participants, mean age 76.7 ± 9.1, who attended an outpatient center where self-report data were recorded. The degree of HV deformity was determined in both feet using the Manchester Scale (MS) from stage 1 (mild) to 4 (very severe). Scores obtained on the Foot Health Status Questionnaire (FHSQ) were compared. This has 13 questions that assess 4 health domains of the feet, namely pain, function, general health and footwear. The stage 4 of HV shown lower scores for the footwear domain (11.23 ± 15.6); general foot health (27.62 ± 19.1); foot pain (44.65 ± 24.5); foot function (53.04 ± 27.2); vigour (42.19 ± 16.8); social capacity (44.46 ± 28.1); and general health (41.15 ± 25.5) compared with stage 1 of HV (P<0.05) and there were no differences of physical activity (62.81 ± 24.6). Often, quality of life decreases in the elderly population based in large part on their foot health. There is a progressive reduction in health in general and foot health with increasing severity of hallux valgus deformity which appears to be associated with the presence of greater degree of HV, regardless of gender.

    ABSTRACT: To discover whether changes in foot morphology and pain tolerance may favor the use of inadequate footwear in old age. 100 participants, mean age 81.60 ± 8.26 years attended an outpatient clinic where self-reported demographic data, frequency checked their feet, measurements of foot sensitivity, foot size and shoe size. Only 19% checked their feet every day, 73% revealed symptoms of neuropathy and 83% used inadequate footwear on at least one foot. In a bivariate analysis, no significant differences were observed. Distinct physical changes affect the feet in the elderly population. Decreased sensitivity and absence of regular foot checks can contribute to use of inadequate footwear. Often, it is necessary to use a different shoe size to ensure that the footwear matches the actual dimensions and true needs of each foot in order to improve functionality and prevent the onset of severe medical conditions and/or foot deformities.

    ABSTRACT: Background: People working at sea show a marked presence of musculoskeletal pain as well as an important coexistence of pain in diverse anatomical regions, which is believed to have a harmful effect on the quality of life related to foot health. The aim is to describe and compare the impact in a sample of sea workers and people who work on the ground in the light of the scores obtained with regard foot health and health in general. Methods: A sample of 94 participants of a mean age of 41.29 ± 10.603 came to a health centre where self-reported data were registered, informants' professional activity was determined and the scores obtained were compared in the Foot Health Status Questionnaire. Results: The sea workers group showed a worse quality of life related to health in general and to foot health specifically. Differences between the two groups were evaluated by means of a t-test for independent samples, showing statistical significance (P < 0.05) for the dimensions of pain and general health related to the foot. Conclusions: People working at sea present a negative impact on the quality of life related to foot health, which appears to be associated with the presence of deformities, sprains, plantar warts and fungus.

    ABSTRACT: Background The purpose of this study was to delineate the relationship of the terminal extensor hallucis longus tendon insertion to the proximal limit of the nail matrix of the great toe.Material and methodsFifty fresh-frozen human cadaver great toes with no evidence of trauma (average age, 62.5 years; 29 males and 21 females) were used for this study. Under 25X magnification, the proximal limit of the nail matrix and the terminal bony insertion of the extensor hallucis longus tendons were identified. The distance from the terminal tendon insertion to the nail matrix was ascertained using precision calipers, an optical microscope, and autocad® software for windows. Twenty-five great toes were placed in a neutral formalin solution and further analysed by histological longitudinal-sections. The specimens were stained with haematoxylin and eosin and examined microscopically to determine the presence of the extensor hallucis longus tendon along the dorsal aspect of the distal phalanx of each great toe.ResultsThe main result we found in great toes was that the extensor tendon is between the matrix and the phalanx and extends dorsally to the distal aspect of the distal phalanx in all, 100%, specimens. The nail matrix of the great toe is not attached to the periosteum of the dorsal aspect of the base of the distal phalanx as is the case for fingers, because the extensor hallucis tendon is plantar or directly underneath the nail matrix and the tendon is dorsal to the bone.Conclusions We have found that the extensor tendon is between the matrix and the phalanx and extends dorsally to the distal aspect of the distal phalanx. The nail matrix of the great toe is not attached to the periosteum of the dorsal aspect of the base of distal phalanx as is the case in fingers, because the extensor hallucis tendon is plantar or directly underneath the nail matrix and the tendon is dorsal to the bone. Our anatomic study demonstrates that the proximal limit of the matrix and nail bed of the human great toe are dorsal and overlapping the terminal extensor hallucis longus tendon until its distal bony insertion in all specimens.

    ABSTRACT: The nursing environment is full of situations under ethical and legal constraints. Therefore this study focused on the knowledge, position and attitudes of nurses in relation to healthcare ethics and nursing legal regulations. We conducted a pretest and posttest study using a specific questionnaire administered to a convenience sample of nurses who worked in a healthcare system in Principado de Asturias, a northern state of Spain and were enrolled in a continuing nursing education program about ethical and legal aspects in the nursing profession. The main findings suggest that nurses are very concerned about situations that create ethical and legal conflicts but do not feel sufficiently trained. In general, they demonstrated sufficient knowledge to address the most frequent ethical and moral situations of nursing work, and the training received during a postgraduate course in ethics and legislation provided them with greater knowledge and tools to solve the dilemmas In conclusion, although the nurses have university-level education about professional deontology, bioethics and nursing legislation, they require periodic continuing education. © 2014, Organizacion Panamericana de la Salud.

    ABSTRACT: Background: Functional hallux limitus (FHL) has been implicated in the development of metatarsophalangeal joint osteoarthritis. Objectives: To determine whether cut-out orthosis treatment increases plantarflexion of the first metatarsal by increasing its declination angle. Study design: Cross-sectional study. Methods: A total of 46 female volunteers with an average age of 25.66 ± 5.70 years (range: 19-42 years) and FHL participated in the study. We assessed the degrees of movement of the first metatarsal and proximal phalanx bones at the first metatarsophalangeal joint without and while wearing the cut-out orthosis using the 3Space Fastrak® via sensors. Results: The movement of the plantarflexión declination angle of the first metatarsal bone was higher using the orthosis 29.84° ± 5.98° versus without orthosis 27.69° ± 5.91° (p < 0.031°). Use of sandals may have minimized the magnitude of movement changes associated with orthosis versus non-orthosis use. Conclusion: The cut-out orthosis demonstrated a beneficial effect on non-fixed first metatarsophalangeal and metatarsal cuneiform joints affected by FHL, significantly increasing the declination of the metatarsal angle. Furthermore, use of the cut-out orthosis significantly reduced adduction movement of the first metatarsal bone in the transverse plane. Clinical relevance: The cut-out orthosis demonstrated a beneficial effect on non-fixed first metatarsophalangeal and metatarsal cuneiform joints affected by FHL, significantly increasing the declination of the metatarsal angle. Furthermore, use of the cut-out orthosis significantly reduced adduction movement of the first metatarsal bone in the transverse plane.

    ABSTRACT: For treatment of ingrown toenails, a phenolization approach is often chosen. Many reports describe a lavage of the wound with alcohol to neutralize any residual phenol; however, it remains uncertain if there is a more effective solution for use in the lavage step. The aim of our study was to analyze the suitability and effectiveness of 0.1% polihexanide solution compared with isopropyl alcohol in the removal of excess phenol after treatment for ingrown toenails. We performed an in vitro study using human matrix and a diffusion cell apparatus to measure the amount of phenol remaining after two lavage washes. The effect of phenol evaporation was also examined.When phenol was irrigated with alcohol alone, 27.43 ± 4.10 mg (57.74%) of the initial amount of phenol was recovered. If irrigated with 0.1% polihexanide, 35.98 ± 2.93 mg (75.74%) of phenol was recovered. These results indicate that a polihexanide lavage step has significantly higher efficiency for removing excess phenol relative to alcohol.

    ABSTRACT: Phenolization is often used to treat ingrown toenails. Alcohol lavage with or without supplemental chlorhexidine may be used to remove residual phenol, which can contribute to side effects such as persistent oozing or drainage. We sought to compare the effectiveness in removing residual phenol of lavage with alcohol plus chlorhexidine versus alcohol alone. We studied 80 patients who underwent unilateral phenol matricectomy: 40 who received irrigation with alcohol alone and 40 who received irrigation with alcohol plus chlorhexidine. Phenol levels were measured after each of 5 rounds of 3-mL irrigations. After the first irrigation, an average of 44.92% and 38.35% of the phenol remained in the nailfold in the alcohol and the alcohol/chlorhexidine groups, respectively (P < .05). After all 5 irrigations, no difference in efficacy between the 2 solutions was found (P > .005). It was not possible to calculate the quantity of phenol initially introduced into the nail bed. The percentage remaining was calculated from the total amount of phenol recovered. When a single irrigation step is performed after phenolization, alcohol plus chlorhexidine is more effective than alcohol alone for removing residual phenol. When multiple irrigations are performed, the 2 solutions are equally effective.

    ABSTRACT: Background: There is a high prevalence of musculoskeletal complaints related to day-to-day work among podiatric physicians. We sought to determine the relationships among musculoskeletal pain, job satisfaction, depression, and anxiety in Spanish podiatric physicians. Methods: A convenience sample of 421 Spanish podiatric physicians was administered a survey that included questions about sociodemographic variables, musculoskeletal pain, job satisfaction, depression, and anxiety. Results: On average, respondents were found to have a high level of pain, a moderate level of job satisfaction, and low-to-moderate levels of depression and anxiety. Young single women had the highest levels of pain and anxiety. Analysis with the Student t test indicated significant differences between the sexes for levels of pain (P < .0001) and anxiety (P < .014). Job satisfaction was inversely related to depression and anxiety. Conclusions: These findings, particularly the increased levels of pain, job dissatisfaction, anxiety, and depression in young single female podiatrists, indicate a need for strategies to reduce the risks posed by the work environment in podiatric medicine, thus minimizing the negative psychological and physical consequences of participating in the profession.

    ABSTRACT: A hamartoma is a benign, focal malformation resembling a neoplasm in its tissue of origin. This malady has not been reported to be manifested in the nail plate. Here, we describe a rare case of hamartoma under the nail plate of the first toe and its successful excision from a 30-year-old woman. We used palpation, radiologic analyses, excisional surgery, and histopathology to determine the presence of a hamartoma under the nail plate of the first toe. Removal of the mass was successful for the patient, and histopathologic analysis revealed characteristics of hamartoma. The presence of a hamartoma under the nail plate of the first toe is a unique finding that should be made aware to the clinical community.

    ABSTRACT: Nursing education and the nursing profession must go hand by hand to emphasize efforts to improve knowledge in ethical decision-making and professional deontology. Te nursing profession in Spain has struggled for legislation of the profession as well as a professional code of ethics. Based on the ethical specifications for nursing practice, it is evident that education in nursing ethics is of the most importance and should be emphasized as an integral component of higher-level nursing education. Nursing schools should seek to establish programs that effectively integrate the humanities with the biotech-nological aspects of the profession and define strategies for monitoring nursing professionals who graduate from those schools.

    ABSTRACT: Transposition of the flexor digitorum longus tendon has been widely reported for the correction of flexible claw and hammertoe deformities. The most common technique uses two cutaneous incisions, one plantar and another dorsal. We performed a cadaveric study to determine whether the flexor digitorum longus tendon could be transferred to the dorsum of the proximal phalanx of the toe from its lateral or medial aspect through a unique single longitudinal central dorsal incision. The rationale for this novel approach was to minimize the risk of vascular compromise to the digit associated with the two-incision approach. Transposition of the flexor digitorum longus tendon was attempted in 120 toes of cadaveric feet (60 each second and third digits) through a central longitudinal dorsal incision. The flexor digitorum longus tendon segment was long enough to be successfully transposed between the flexor digitorum brevis hemitendons of the second and third toes in 100% of the cases using the central longitudinal dorsal incision approach, with a resection arthroplasty at the proximal interphalangeal joint. Transfer of the flexor digitorum longus tendon to the dorsum of the proximal phalanx can be performed for the correction of claw and hammertoe deformities in the second and third digits. The meticulous longitudinal incision of the flexor tendon sheath to expose the flexor digitorum brevis tendon and its longitudinal incision are essential to the successful transfer of the flexor digitorum longus tendon between the flexor digitorum brevis hemitendons.
