Improvement in clinical outcomes following arthroscopic all-inside medial lateral ligament reconstruction for rotational ankle instability.

PURPOSE: Rotational ankle instability can be diagnosed in up to 18% of cases of chronic lateral ankle instability. It is characterised by an abnormal increase of talar rotation within the tibiofibular mortise, due to an injury in the most anterior component of the deltoid ligament secondary to a chronic deficiency of the lateral collateral ligament. The aim of this prospective observational study was to investigate the clinical outcomes following arthroscopic all-inside medial and lateral ligament reconstruction for rotational ankle instability. METHODS: A prospective observational study of consecutive patients undergoing arthroscopic all-inside medial and lateral ligament reconstruction for rotational ankle instability with minimum 6-month follow-up. The primary outcome was a validated patient-reported outcome measure (PROM), the Manchester-Oxford Foot Questionnaire. Secondary outcomes included the EQ-5D, European Foot and Ankle Society score and complications. RESULTS: Between 2020 and 2023, 12 patients underwent primary arthroscopic all-inside medial and lateral ligament reconstruction for rotational ankle instability with pre- and post-operative PROMs available for all 12 patients. The mean ± standard deviation age was 33.9 ± 7.2 years and the mean follow-up was 1.9 ± 1.2 (range: 0.5-3.8, interquartile range: 0.9-3.0) years. There was a significant improvement in all Manchester-Oxford Foot Questionnaire domain scores (p < 0.05): Index 53.1 ± 19.1 to 26.4 ± 27.6, Pain 46.7 ± 20.3 to 26.2 ± 26.8, Walking/Standing 58.7 ± 26.0 to 27.0 ± 30.0 and Social Interaction 51.2 ± 19.5 to 25.6 ± 30.1. There were improvements in EQ-5D-5L Index, VAS and VAS Pain; however, these were not statistically significant. There was one complication-a superficial peroneal nerve injury which resolved with a corticosteroid injection. CONCLUSION: The arthroscopic all-inside medial and lateral ligament reconstruction technique is a reliable and safe method for treating rotational ankle instability, demonstrating significant improvement in PROMs at a mean 1.9-year follow-up. LEVEL OF EVIDENCE: Level IV.

Cartiva interpositional arthroplasty versus arthrodesis in the treatment of Hallux rigidus: A retrospective comparative study with mean 2 year follow up.

BACKGROUND: Hallux rigidus is a common condition characterised by first metatarsophalangeal joint (MTPJ) degeneration, pain and limited range of motion (ROM). The gold standard surgical treatment is arthrodesis, providing good pain relief, but sacrifices ROM. The Cartiva synthetic cartilage implant (SCI) has been utilised as an interpositional arthroplasty, aiming to reduce pain whilst preserving range of motion. Current evidence for Cartiva SCI is limited. The aim was to evaluate the clinical outcomes of Cartiva SCI compared to arthrodesis undertaken in our centre. METHODS: A retrospective cohort study was conducted, enrolling all adult patients who underwent primary first MTPJ SCI arthroplasty or arthrodesis for the treatment hallux rigidus. The primary outcome was a validated patient-reported outcome measure (PROM), the Manchester-Oxford Foot Questionnaire (MOXFQ). Secondary outcomes included EQ-5D, complication rates, VAS Pain and FAAM (ADL). RESULTS: Between 2017 and 2020 there were 33 cases divided into two groups (17 Cartiva SCI, 16 arthrodesis, mean age 59.0 ± 9.9 years) with a mean follow up of 2.3 years. There was no statistically significant difference in any of the MOXFQ, EQ-5D, VAS Pain or FAAM (ADL) outcome scores between the Arthrodesis and SCI groups (p > 0.05). The mean MOXFQ Index score was 7.2 ± 6.4 for the SCI group and 3.9 ± 5.8 for the Arthrodesis group at final follow up (p = 0.15). Although complications were high in both groups, the overall hallux reoperation rate was 29.4 % in the SCI cohort and 0.0 % for arthrodesis. CONCLUSION: This retrospective comparative study found no significant superiority of Cartiva SCI over arthrodesis in terms of PROMs. Due to the higher rate of further surgical intervention in the SCI cohort, we recommend arthrodesis as the preferred surgical option for hallux rigidus. LEVEL OF EVIDENCE: III.

Remimazolam sedation for awake tracheal intubation.

We present a case of a 55-year-old woman presenting for an elective minor procedure. Following a previous anaesthetic, a 'can't intubate, can't oxygenate' incident had been documented. She had since undergone awake tracheal intubation for procedures requiring general anaesthesia. We were able to safely facilitate awake tracheal intubation using remimazolam for sedation. Remimazolam is a novel ultra-short acting benzodiazepine with similar pharmacodynamic effects to its parent compound midazolam, having minimal cardiovascular or respiratory effects and offering excellent anxiolysis and amnesia. It has a significantly shorter duration of action than midazolam, making it a valuable sedative agent for awake tracheal intubation. The patient remained stable throughout the procedure, with minimal effects on the respiratory and cardiovascular systems. The quality of sedation was reported as highly satisfactory by both the patient and the team.

Exploring the Role of Determinants Affecting Responsible Underwater Behaviour of Marine-Based Tourists.

This study utilised divers' demographic characteristics, diving experience, and attitudes to analyse the association between these factors and divers' responsible underwater behaviour among Chinese scuba divers in Hong Kong. More innovatively, the measurement construct of diving attitude was further employed as a mediator to investigate its influence on the relationship between divers' diving experience and responsible underwater behaviours based on the conceptual framework of previous works in the literature. The questionnaire data for this study were collected at four of the most popular dive sites among the marine protected areas in Hong Kong, with 398 valid samples after eliminating incomplete questionnaires. Regression results demonstrated that divers' demographic characteristics could significantly predict their responsible underwater behaviour, with age (b = 0.10, p < 0.05) and education (b = 0.15, p < 0.05) being found to be positively associated with their diving behaviour. In addition, path analysis demonstrated that divers' diving experience and attitude could explain 13.6% and 22.6% of the variance in predicting their responsible diving behaviour, respectively. However, no mediation effect was found on the relationship between diving experience and responsible underwater behaviour relative to diving attitude, given the absence of statistical effects regarding the positive impact of divers' diving experience on their attitude (ß = 0.024, se = 0.022, t = 1.085, p = 0.279). Based on the research findings, theoretical and practical implications were discussed correspondingly, which are believed to be beneficial in promoting marine conservation and the sustainable development of marine-based nature tourism in Hong Kong.

Factors related to obstetric third and fourth degree perineal lacerations in a jamaican cohort / Factores relacionados con las laceraciones perineales obstétricas de tercer y cuarto grado en una cohorte de Jamaica

OBJECTIVES: The aim of this study was to identify significant and modifiable risk factors associated with obstetric third and fourth degree perineal lacerations and to produce recommendations that may reduce their morbidity and prevalence. METHODS: This is a retrospective case control study performed between March 2004 and March 2008. All patients diagnosed with third and fourth degree perineal lacerations were identified (cases) along with randomly assigned controls who delivered during the same time period. Nineteen cases and 38 controls were identified giving a total of 57 patients. Each patient's hospital record was collected and the data extracted. RESULTS: When analysed for weight greater than or equal to 3.5 kg versus birthweight of less than 3.5 kg, the difference between cases and controls was found to be statistically significant, with a p value of 0.012. Of the cases, 21% had an operative delivery (forceps or vacuum) whereas only 2.6% of the controls had an operative delivery. This was found to be statistically significant (p = 0.011). CONCLUSIONS: This study has shown that the two main factors related to the obstetric third and fourth degree perineal lacerations were babies weighing more than 3.5 kg and the use of forceps or vacuum to assist with deliveries. These high risk patients should be attended to by the most senior staff that is available.

OBJETIVOS: El objetivo de este estudio fue identificar factores de riesgo modificables y significativos asociados con las laceraciones perineales obstétricas de 3er y 4to grado, y producir recomendaciones que puedan reducir su morbilidad y prevalencia. MÉTODOS: Se trata de un estudio de caso control retrospectivo realizado entre marzo de 2004 y marzo de 2008. Todas las pacientes diagnosticadas con laceraciones perineales de 3er y 4to grado fueron identificadas (casos) con controles asignados de manera aleatoria, que tuvieron el parto en el mismo período de tiempo. Diecinueve casos y 38 controles fueron identificados, para un total de 57 pacientes. Se recogieron y se extrajeron los datos de las historias clínicas de cada paciente. RESULTADOS: Al analizárseles en términos de peso superior o igual a 3.5 kg frente a un peso al nacer por debajo de 3.5 kg, la diferencia entre los controles y los casos resultó ser estadísticamente significativa, con un valor p de 0.012. De los casos, el 21% tuvo un parto operativo (fórceps o vacío), mientras que sólo el 2.6% de los controles tuvo un parto operativo. Esto resultó ser estadísticamente significativo (p = 0.011). CONCLUSIONES: Este estudio ha demostrado que los dos factores principales relacionados con las laceraciones perineales obstétricos de 3er y 4to grado, eran bebés con un peso de más de 3.5 kg y el uso de fórceps o vacío en la asistencia a los partos. Estos pacientes de alto riesgo deben ser atendidos por el personal disponible de mayor experiencia.

Management of obstetric anal sphincter injuries at the University Hospital of the West Indies / Tratamiento de las lesiones obstétricas del esfínter anal en el Hospital Universitario de West Indies

Up to 6% of women sustain severe perineal lacerations that involve the anal sphincters during vaginal delivery. When they occur, obstetric anal sphincter injuries (OASI) may be accompanied by significant morbidity. Therefore, it is important to detect these injuries promptly and for experienced staff to perform sound repair. This report retrospectively assesses a series of seven women with OASI who were managed at a tertiary level hospital in Jamaica over a period of 28 months. Unfavourable details of management that may have adversely affected outcomes were sought from the various cases treated. The incidence of OASI was low (0.2%). There were five third degree and two fourth degree lacerations. After these injuries were repaired, three patients (43%) experienced morbidity such as chronic pelvic pain (43%), anal incontinence (29%), dyspareunia (23%) and recto-vaginal fistulae (14%). In order to improve the outcomes at this institution, several aspects of current care can be improved. Operative repair of these injuries should be delayed until senior staff is available to supervise OASI repair. Both methods of sphincter repair are reasonable options but the use of rapidly absorbable sutures is not appropriate. Finally, prophylaxis against wound infections can be achieved by administering a single dose of intravenous second or third generation cephalosporin at the time of induction of anaesthesia.

Hasta el 6% de las mujeres sufren desgarramientos perineales severos que involucran los esfínteres anales durante el parto vaginal. Cuando ocurren, las lesiones obstétricas del esfínter anal (OASI) pueden estar acompañadas por morbilidad significativa. Por consiguiente, es importante descubrir estas lesiones rápidamente, para que el personal experimentado lleve a cabo una buena reparación quirúrgica. Este informe evalúa retrospectivamente una serie de siete mujeres con OASI, tratadas en un hospital de nivel terciario en Jamaica, durante un periodo de 28 meses. Se buscaron detalles desfavorables del tratamiento que puedan haber afectado adversamente la evolución clínica de los varios casos tratados. La incidencia de las OASI fue baja (0.2%). Hubo cinco desgarramientos de tercer grado y dos laceraciones de cuarto grado. Después de que estas lesiones fueron reparadas, tres pacientes (43%) experimentaron morbilidad, tal como dolor pélvico crónico (43%), incontinencia anal (29%), dispareunia (23%) y fístulas recto-vaginales (14%). A fin de mejorar los resultados clínicos en esta institución, pueden mejorarse varios aspectos del cuidado actual. La reparación operativa de estas lesiones debe retardarse hasta que esté disponible un personal de experiencia para supervisar la reparación de la OASI. Ambos métodos de reparación del esfínter constituyen opciones razonables, pero el uso de suturas rápidamente absorbibles no es apropiado. Finalmente, puede lograrse la profiláxis contra las infecciones de las heridas, administrando una sola dosis de cefalosporina intravenosa de segunda o tercera generación en el momento de inducción de la anestesia.

A clinical audit of the quality of care of hypertension in general practice / Una Auditoría Clínica de la Calidad del Cuidado de la Hipertensión en la Práctica Médica General

Clinical audits monitor the use of particular interventions, or the care received by patients, against agreed standards. Any departures from [quot ]best practice[quot ] can then be examined, and causes can be determined and acted upon. The Ministry of Health (MOH), Jamaica, has recently published standards of care for hypertension. The medical records of a convenience sample of 125 hypertensive patients being managed by five current family medicine residents in their respective primary care practices were audited Initial results showed limited adherence to the MOH recommended hypertension management guidelines. The same practices were re-audited after an interval of six months, during which time the physicians were sensitized to the results of the preliminary audit. Marked improvements were noted in the second audit. Assessment for co-risk factors for hypertension-related diseases improved: nutritional advice (33% to 74%), smoking and alcohol intake history (40% to 65%) and history taking of physical activity (30% to 47%). Assessment for target organ damage also improved: fundoscopy done (11% to 54%), foot examination done (30% to 58%) and yearly electrolytes done (28% to 62%). There are clear gaps between current practice and standards that exist internationally and locally for management of hypertension. The MOH needs to disseminate and educate general practitioners about the standards of care guidelines

Los auditores clínicos monitorean el uso de intervenciones particulares, o la atención recibida por los pacientes, a fin de verificar si se cumplen las normas establecidas. Cualquier desviación de "la práctica estándar" puede ser entonces analizada, determinándose de ese modo las causas, y empren-diéndose las correspondientes acciones sobre ellas. El Ministerio de Salud (MS) de Jamaica, ha publicado recientemente las normas del cuidado de la hipertensión. A las historias clínicas de una muestra de conveniencia de 125 pacientes hipertensos tratados por cinco residentes de medicina familiar en sus respectivas consultas de atención primaria, se les practicó una auditoría. Los resul-tados iniciales mostraron una correspondencia limitada con las pautas para el tratamiento de la hipertensión recomendadas por el MS. Las mismas prácticas fueron sometidas de nuevo a auditoría, luego de un intervalo de seis meses, durante el cual se sensibilizó a los médicos con los resultados de la auditoría preliminar. En la segunda auditoría se observaron mejorías considerables. Mejoró la evaluación de los factores de co-riesgo por enfermedades relacionadas con la hipertensión: consejo nutricional (33% a 74%), historia de hábito de fumar y consumo de alcohol (40% a 65%), confección de historia de la actividad física (30% a 47%). También mejoró la evaluación de daños dirigida a órganos predeterminados: fondoscopia realizada (11% a 54%), examen de pies realizado (30% a 58%) y electrólitos anuales hechos (28% a 62%). Evidentemente hay lagunas entre la práctica común y las normas existentes internacional y localmente para el tratamiento de hipertensión. El MS necesita diseminar y educar médicos generales versados en las normas de cuidado establecidas.
