RESUMO

Angioleiomyoma is a rare benign soft tissue tumour arising from smooth muscle, representing <1% of upper limb soft tissue tumours. We report a 54-year-old male presenting with a progressively enlarging atraumatic lesion along the palmar side of the base of the ring and little finger. A biopsy was done to determine the diagnosis. Intraoperatively, the lump was found to be intimately related to the radial digital artery, it could not be excised en-bloc without transecting the radial digital artery of the little finger. Following excision, the ends of the digital artery were anastomosed. At 10-months follow-up, the hand was fully functional without any evidence of cold-intolerance or neurological deficit along the distribution of the digital nerve. We review the literature on angioleiomyoma and report careful resection of the tumour with digital artery transection and repair as a treatment option for angioleiomyoma of the digital artery. Level of Evidence: Level V (Therapeutic).

RESUMO

Chondral injury is a serious consequence of patellar dislocation and patellofemoral instability (PFI). There is limited data on the relationship between radiological features such as sulcus angle and patellar height to the presence, location, and severity of chondral lesions. The purpose of this study was to determine the association of anatomical variants in patellofemoral instability with injuries sustained due to patellar dislocation. A cohort of 101 patients who had four or more episodes of dislocation or instability undergoing isolated arthroscopy or arthroscopies at the time of corrective realignment surgery were identified. The prevalence of chondral, ligamentous, and meniscal injuries was determined and correlated to the sulcus angle, tibial tubercle trochlear groove distance, and patellar height on magnetic resonance imaging (MRI) scans. A total of 101 patients was identified. At arthroscopy, the patella demonstrated the highest incidence of chondral injury (68%) followed by the trochlear groove (40%). Lateral meniscal injuries were noted in 6% of patients, medial meniscal injuries in 2%, and anterior cruciate ligament (ACL) injury in 3%. Chondral injuries were graded using the Outerbridge criteria and there was a correlation between more severe chondral injuries and a greater tilt angle (p = 0.05). The occurrence of injury to the lateral meniscus was associated with a higher Insall-Salvati ratio (p = 0.05). More severe chondral injuries are seen in patients with a greater tilt angle.

RESUMO

BACKGROUND: Despite contributing to significant morbidity in working-age adults, there is no consensus on the optimal treatment for prepatellar bursitis. Much of the existing literature combines prepatellar and olecranon bursitis. This systematic review aims to determine the optimal management of prepatellar bursitis. STUDY DESIGN AND METHODS: A primary search of electronic published and unpublished literature databases from inception to November 2019 was completed. Articles over 25 years old, case reports with less than four patients, paediatric studies, and non-English language papers were excluded. Our primary outcome was recurrence after 1 year. Comparisons included endoscopic vs open bursectomy, duration of antibiotics. Methodological quality was assessed using the Institute of Health Economics and Revised Cochrane Risk of Bias scoring systems. Meta-analyses were conducted where appropriate. RESULTS: In total 10 studies were included (N = 702). Endoscopic and open bursectomy showed no difference in recurrence after 1 year (OR 0.41, 95% CI 0.05-3.53, p = 0.67), and surgical complications (OR 1.44, 95% CI 0.34-6.08, p = 0.44). 80% endoscopically-treated patients were pain free after 1 year. Patients treated with antibiotics for less than 8 days were not significantly more prone to recurrence (2/17 vs 10/114, OR 0.66, 95% CI 0.13-3.29, p = 0.64) compared to 8 days plus at minimum 1 year post injury. CONCLUSIONS: Our study represents the largest cohort of patients evaluating management strategies for prepatellar bursitis, and includes data not previously published. Endoscopic bursectomy is non-inferior to open bursectomy, enabling a shorter hospital stay. It also offers a relatively low risk of post-operative pain. Endoscopic bursectomy is a viable option to treat both septic and aseptic prepatellar bursitis. Our small cohort suggests recurrence and hospital stay are not improved with antibiotic treatment exceeding 7 days for septic prepatellar bursitis.

RESUMO

OBJECTIVE: This study aims to evaluate the relationship between a single measurement at baseline of body mass index (BMI), glycated hemoglobin (HbA1c) and subsequent clinical outcomes in patients with type 2 diabetes mellitus (T2DM). METHOD: Patients with T2DM were recruited from an outpatient diabetes clinic in a single large teaching hospital in Kingston upon Hull, UK. At baseline, demographics and HbA1c were recorded. Patients were categorized by BMI: normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), and obese (>30 kg/m2). Multivariable Cox regression models that included demographic, risk factors, and comorbidities were separately constructed for all-cause, cardiovascular, cancer and sepsis-related mortality, using four groups of HbA1c (<6%, 6.0-6.9%, 7.0-7.9%, and >8%). RESULTS: In total, 6220 patients with T2DM (median age 62 years, 54% male) were followed for a median of 10.6 years. HbA1c levels >8.0% were associated with increased risk of all-cause mortality and cardiovascular death. However, this increased risk was not consistent across the weight categories and reached statistical significance only in overweight patients (BMI 25-29.9 kg/m2). CONCLUSIONS: In a large cohort of patients with T2DM elevated HbA1c levels at baseline did not consistently predict increased risk of all-cause and cardiovascular mortality across the different BMI categories.

RESUMO

INTRODUCTION: Kinesiophobia, the fear of physical movement and activity related to injury vulnerability, has been linked to sub-optimal outcomes following total knee replacement (TKR). This systematic review has two aims: to define the relationship between kinesiophobia and functional outcomes, pain and range of motion following TKR, and to evaluate published treatments for kinesiophobia following TKR. MATERIALS AND METHODS: A primary search of electronic databases, grey literature, and trial registries was performed in March 2020. English-language studies recruiting adult primary TKR patients, using the Tampa Scale of Kinesiophobia (TSK) were included. Outcome measures were grouped into short (< 6 months), medium (6-12 months), and long term (> 12 months). Study quality was assessed using the Newcastle Ottawa Scale for cohort or case control studies, and the Cochrane Collaboration Risk of Bias tool for randomised controlled trials. RESULTS: All thirteen included papers (82 identified) showed adequately low risk of methodological bias. TSK1 (activity avoidance) correlated with WOMAC functional score at 12 months in three studies (r = 0.20 p < 0.05, R = 0.317 p = 0.001, and correlation coefficient 0.197 p = 0.005). TSK score significantly correlated with mean active range of motion (ROM) at 2 weeks [65.98 (SD = 14.51) versus 47.35 (SD = 14.48) p = 0.000], 4 weeks [88.20 (SD = 15.11) versus 57.65 (SD = 14.80) p = 0.000], and 6 months [105.33 (SD = 12.34) versus 85.53 (SD = 14.77) p = 0.000] post-operation. Three post-operative interventions improved TSK score vs control following TKR: a home-based functional exercise programme [TSK - 14.30 (SD = 0.80) versus - 2.10 (SD = 0.80) p < 0.001], an outpatient cognitive behavioural therapy (CBT) programme [TSK 27.76 (SD = 4.56) versus 36.54 (SD = 3.58)], and video-based psychological treatment [TSK 24 (SD = 5) versus 29 (SD = 5) p < 0.01]. CONCLUSIONS: Kinesiophobia negatively affects functional outcomes up until 1 year post-operatively, while active ROM is reduced up to 6 months post-procedure. Post-operative functional and psychological interventions can improve kinesiophobia following TKR.

RESUMO

BACKGROUND AND OBJECTIVES: The majority of patients included in trials of anti-platelet therapy are male. This systematic review and meta-analysis aimed to determine whether, in addition to aspirin, P2Y12 blockade is beneficial in both women and men with acute coronary syndromes. METHODS: Electronic databases were searched and nine eligible randomised controlled studies were identified that had sex-specific clinical outcomes (n=107,126 patients). Risk Ratios (RR) and 95% Confidence Intervals (CI) were calculated for a composite of cardiovascular death, myocardial infarction or stroke (MACE), and a safety endpoint of major bleeding for each sex. Indirect comparison analysis was performed to statistically compare ticagrelor against prasugrel. RESULTS: Compared to aspirin alone, clopidogrel reduced MACE in men (RR, 0.79; 95% CI, 0.68 to 0.92; p=0.003), but was not statistically significant in women (RR, 0.88; 95% CI, 0.75 to 1.02, p=0.08). Clopidogrel therapy significantly increased bleeding in women but not men. Compared to clopidogrel, prasugrel was beneficial in men (RR, 0.84; 95% CI, 0.73 to 0.97; p=0.02) but not statistically significant in women (RR, 0.94; 95% CI, 0.83 to 1.06; p=0.30); ticagrelor reduced MACE in both men (RR, 0.85; 95% CI, 0.77 to 0.94; p=0.001) and women (RR, 0.84; 95% CI, 0.73 to 0.97; p=0.02). Indirect comparison demonstrated no significant difference between ticagrelor and prasugrel in either sex. Compared to clopidogrel, ticagrelor and prasugrel increased bleeding risk in both women and men. CONCLUSION: In summary, in comparison to monotherapy with aspirin, P2Y12 inhibitors reduce MACE in women and men. Ticagrelor was shown to be superior to clopidogrel in both sexes. Prasugrel showed a statistically significant benefit only in men; however indirect comparison did not demonstrate superiority of ticagrelor over prasugrel in women.

RESUMO

Cardiogoniometry (CGM) is method of 3-dimensional electrocardiographic assessment which has been shown to identify patients with angiographically defined, stable coronary artery disease (CAD). However, angiographic evidence of CAD, does not always correlate to physiologically significant disease. The aim of our study was to assess the ability of CGM to detect physiologically significant coronary stenosis defined by fractional flow reserve (FFR). In a tertiary cardiology centre, elective patients with single vessel CAD were enrolled into a prospective double blinded observational study. A baseline CGM recording was performed at rest. A second CGM recording was performed during the FFR procedure, at the time of adenosine induced maximal hyperaemia. A significant CGM result was defined as an automatically calculated ischaemia score < 0 and a significant FFR ratio was defined as < 0.80. Measures of diagnostic performance (including sensitivity and specificity) were calculated for CGM at rest and during maximal hyperaemia. Forty-five patients were included (aged 61.1 ± 11.0; 60.0% male), of which eighteen (40%) were found to have significant CAD when assessed by FFR. At rest, CGM yielded a sensitivity of 33.3% and specificity of 63.0%. At maximal hyperaemia the sensitivity and specificity of CGM was 71.4 and 50.0% respectively. The diagnostic performance of CGM to detect physiologically significant stable CAD is poor at rest. Although, the diagnostic performance of CGM improves substantially during maximal hyperaemia, it does not reach sufficient levels of accuracy to be used routinely in clinical practice.

RESUMO

BACKGROUND AND PURPOSE: The primary cannabinoids, Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and Delta(8)-tetrahydrocannabinol (Delta(8)-THC) are known to disturb the mitochondrial function and possess antitumor activities. These observations prompted us to investigate their effects on the mitochondrial O(2) consumption in human oral cancer cells (Tu183). This epithelial cell line overexpresses bcl-2 and is highly resistant to anticancer drugs. EXPERIMENTAL APPROACH: A phosphorescence analyzer that measures the time-dependence of O(2) concentration in cellular or mitochondrial suspensions was used for this purpose. KEY RESULTS: A rapid decline in the rate of respiration was observed when Delta(9)-THC or Delta(8)-THC was added to the cells. The inhibition was concentration-dependent, and Delta(9)-THC was the more potent of the two compounds. Anandamide (an endocannabinoid) was ineffective; suggesting the effects of Delta(9)-THC and Delta(8)-THC were not mediated by the cannabinoidreceptors. Inhibition of O(2) consumption by cyanide confirmed the oxidations occurred in the mitochondrial respiratory chain. Delta(9)-THC inhibited the respiration of isolated mitochondria from beef heart. CONCLUSIONS AND IMPLICATIONS: These results show the cannabinoids are potent inhibitors of Tu183 cellular respiration and are toxic to this highly malignant tumor.
