Bladder neck contracture following transurethral surgery of prostate: a retrospective single-center study.

PURPOSE: Bladder neck contracture (BNC) is a rare but intolerant complication after transurethral surgery of prostate. The present study aims to investigate the incidence and risk factors of BNC in patients diagnosed benign prostate hyperplasia (BPH) and following transurethral resection or enucleation of the prostate (TURP/TUEP). METHODS: This retrospective study included 1008 BPH individuals who underwent transurethral surgery of the prostate between January 2017 and January 2022. Patients' demographics, medical comorbidities, urologic characteristics, perioperative parameters, and the presence of BNC were documented. Univariate and multivariate analyses were conducted to identify the risk factors. RESULTS: A total of 2% (20/1008) BPH patients developed BNC postoperatively and the median occurring time was 5.8 months. Particularly, the incidences of BNC were 4.7% and 1.3% in patients underwent Bipolar-TURP and TUEP respectively. Preoperative urinary tract infection (UTI), elevated PSA, smaller prostate volume (PV), bladder diverticulum (BD), and B-TURP were significantly associated with BNC in the univariate analysis. Further multivariate logistic regression demonstrated preoperative UTI (OR 4.04, 95% CI 2.25 to 17.42, p < 0.001), BD (OR 7.40, 95% CI 1.83 to 31.66, p < 0.001), and B-TURP (OR 3.97, 95% CI 1.55 to 10.18, p = 0.004) as independent risk factors. All BNC patients were treated with transurethral incision of the bladder neck (TUIBN) combined with local multisite injection of betamethasone. During a median follow-up of 35.8 months, 35% (7/20) of BNC patients recurred at a median time of 1.8 months. CONCLUSION: BNC was a low-frequency complication following transurethral surgery of prostate. Preoperative UTI, BD, and B-TURP were likely independent risk factors of BNC. TUIBN combined with local multisite injection of betamethasone may be promising choice for BNC treatment.

Risk factors for burn contractures: A cross-sectional study in a lower income country.

Risk factors for burn contractures require further study, especially in low and middle-income countries (LMICs); existing research has been predominantly conducted in high income countries (HICs). This study aimed to identify risk factors for burn contractures of major joints in a low-income setting. Potential risk factors (n = 104) for burn contracture were identified from the literature and a survey of clinicians with extensive experience in low and middle-income countries (LMIC). An observational cross-sectional study of adult burn survivors was undertaken in Bangladesh to evaluate as many of these risk factors as were feasible against contracture presence and severity. Forty-eight potential risk factors were examined in 48 adult patients with 126 major joints at risk (median 3 per participant) at a median of 2.5 years after burn injury. Contractures were present in 77% of participants and 52% of joints overall. Contracture severity was determined by measurement of loss of movement at all joints at risk. Person level risk factors were defined as those that were common to all joints at risk for the participant and only documented once, whilst joint level risk factors were documented for each of the participant's included joints at risk. Person level risk factors which were significantly correlated with loss of range of movement (ROM) included employment status, full thickness burns, refusal of skin graft, discharged against medical advice, low frequency of follow up and lack of awareness of contracture development. Significant joint level risk factors for loss of ROM included anatomical location, non-grafted burns, and lack of pressure therapy. This study has examined the largest number of potential contracture risk factors in an LMIC setting to date. A key finding was that risk factors for contracture in low-income settings may differ substantially from those seen in high income countries, which has implications for effective prevention strategies in these countries. Better whole person and joint outcome measures are required for accurate determination of risk factors for burn contracture. Recommendations for planning and reporting on future contracture risk factor studies are made.

Burn contracture risk factors and measurement in low-middle income countries: A clinical perspective.

We find a lack of high-quality published evidence on risk factors for burn contracture formation. The vast majority of research is from High Income Countries (HICs), where many potential risk factors are controlled for by standardised and high-quality healthcare systems. To augment the published literature, burn care professionals with Low Middle Income Countries (LMICs) experience were interviewed for their opinion on risk factors for burn contracture formation. Participants were also asked for their views on identification and measurement of contracture. Seventeen semi-structured interviews were conducted (13 burn surgeons and 4 therapists). The average length of experience in burn-care was 13 years. Participants represented Ghana, Ethiopia, Malawi, Nigeria, South Africa, Nepal, and India. Participants reported ninety risk factors. Risk factors were later collated according to topic: Non burn individual factors (n = 13), Burn injury factors (n = 14), Family and community factors (n = 9), Treatment factors (n = 18), Complications (n = 2), Healthcare capacity factors (n = 19) and Societal and environmental factors (n = 12). The top five most frequently cited risk factors were lack of splinting, lack of physiotherapy, lack of early excision and skin grafting, low socioeconomic status and presence of infection. Although participants had no doubts that they could recognise a contracture, none provided a standardised system of measurement or an operational definition of contracture. Burn care professionals have a wealth of experience and untapped knowledge of risk factors for burn contracture formation in their own population base, but many of the risk factors highlighted by participants have not yet been explored in the literature. Variations in clinicians' diagnosis and measurement of a burn contracture underscores the need for an agreed, standardised, simple and easily reproducible method of diagnosing and classifying burn contractures.

Capsular Contracture Rate in Augmentation Mammoplasty With Motiva Breast Implant Insertion: A Single-Center Experience in Korea.

BACKGROUND: Capsular contracture is the most common complication following breast implant surgery, and the implant shell characteristics are important in preventing this complication. OBJECTIVES: The aim of this study was to evaluate the capsular contracture rate for SmoothSilk Motiva implants (Establishment Labs Holdings Inc., New York, NY) in females who underwent primary and revisional breast augmentation over a 3-year period. METHODS: A total of 1324 cases that took place from 2017 to 2020 were retrospectively analyzed, with 1027 being primary surgeries and 297 being revisional surgeries. RESULTS: In the 1324 cases of augmentation mammoplasty with SmoothSilk Motiva implants, the overall capsular contracture rate was 1.8% (n = 24). The capsular contracture rate in the 1027 primary surgery cases was 1.07% (n = 11), and the capsular contracture rate in the 297 revisional surgery cases was significantly different at 4.39% (n = 13, P = .0001). More specifically, the capsular contracture rate in 182 revisional surgery for cases without capsular contracture was 1.12% (n = 2), and it showed no statistically significant difference from the rate in primary surgery cases (P = .965). However, the rate in 115 revisional surgery for cases with capsular contracture was 9.57% (n = 11), and it showed a statistically significant difference from the rate in primary surgery cases (P = .000) and the rate in revisional surgery for cases without capsular contracture (P = .001). CONCLUSIONS: Augmentation mammoplasty with SmoothSilk Motiva implants demonstrated a lower rate of capsular contracture than traditional smooth or textured implants. Revisional surgery for cases without capsular contracture showed a similar rate of capsular contracture to primary surgery cases, but the rates were higher in revisional surgery for cases with capsular contracture.

Epidemiology and Predictors for Cervical Burn Scar Contractures: A Multicenter Cohort Study.

Cervical burn scar contracture (BSC) affects many important neck functions and the patients' quality of life. However, it remains unclear which patients have a higher risk of neck BSCs. This study aimed to describe the epidemiology and identify the independent risks of cervical BSC formation and severity. Clinical and demographic data of 106 patients with burn scars were retrospectively collated and analyzed from 3 different Chinese hospitals between December 2016 and December 2020. Both univariate and multivariate logistic regression analyses were performed to identify the independent risks for BSC formation and severity at 12 months postburn. Lateral flexion was the most common plane of motion (POM) limited by contractures (29.4%), whereas the POM most commonly limited by severe contractures was the extension (24.6%). Most patients with contractures had those in 3 to 4 POMs (72.1%). Neck skin grafting was an independent risk factor for BSC formation, and cervical and cervicothoracic skin grafting were independent risk factors for BSC severity. These results may help to identify high-risk patients with contractures in the early stages of burns to carry out individualized early prevention and treatment.

Establishment and validation of a nomogram to predict the neck contracture after skin grafting in burn patients: A multicentre cohort study.

Cervical burn contracture is one of the burn contractures with the highest incidence and severity, and there is no effective method to predict the risk of neck contracture. This study aimed to investigate the effect of combined cervicothoracic skin grafting on the risk of neck contracture in burn patients and to develop a nomogram to predict the risk of neck contracture after skin grafting in burn patients. Data from 212 patients with burns who underwent neck skin grafting were collected from three hospitals, and the patients were randomly divided into training and validation sets. Independent predictors were identified through univariate and multivariate logistic regression analyses and incorporated into a prognostic nomogram. Its performance was assessed using the receiver operating characteristic area under the curve, calibration curve, and decision curve analysis. Burn depth, combined cervicothoracic skin grafting, graft thickness, and neck graft size were significantly associated with neck contractures. In the training cohort, the nomogram had an area under the curve of 0.894. The calibration curve and decision curve analysis indicated good clinical applicability of the nomogram. The results were tested using a validation dataset. Combined cervicothoracic skin grafting is an independent risk factor for neck contracture. Our nomogram demonstrated excellent performance in predicting neck contracture risk.

Can the Sup-ER Protocol Decrease the Prevalence and Severity of Elbow Flexion Deformity in Brachial Plexus Birth Injuries?

BACKGROUND: Brachial plexus birth injuries (BPBIs) can often result in functional and cosmetic deficits including, according to a recent scoping review, elbow flexion contractures in up to 48%. A treatment algorithm that includes a custom long-arm orthosis to optimize early glenohumeral joint positioning (Sup-ER protocol) has been shown to improve shoulder range of motion. Although the protocol was not intentionally designed to affect the elbow, this study investigates the prevalence and severity of elbow flexion contractures in children treated with that protocol. METHODS: This prospective cross-sectional cohort study examined 16 children aged 4 and older with BPBI severe enough to be treated with the Sup-ER protocol. Passive and active elbow flexion and extension range of motion (ROM) were assessed in both arms. Elbow flexion contractures were defined as > 5o from neutral. RESULTS: Within the cohort of 16 patients (mean age: 7.0 years, range: 4.5-11.6 years), the mean maximal passive elbow extension was -6.2° in the affected arm and + 5.1° (hyperextension) in the unaffected arm. Zero patients had a severe elbow flexion contracture (>30o) and only 6/16 met the lowest threshold definition of elbow flexion contracture (>5o), with a mean onset at 22 months of age. CONCLUSIONS: This study suggests an unintended decreased prevalence and severity of elbow flexion contractures in children with more severe BPBI treated with the Sup-ER protocol, relative to published values.

Prevalence of knee contractures is high in children with cerebral palsy in Denmark.

INTRODUCTION: Cerebral palsy (CP) is a neurological disease occurring in children at early gestation, often resulting in pronounced functional limitations. A Swedish cross-sectional study (Cloodt, et al., 2018) discovered that 22% of children with CP had a knee contracture, which was associated with higher levels of Gross Motor Function Classification System (GMFCS), higher age, and higher levels of spasticity measured by the Modified Ashworth Scale (MAS). The current study investigated these associations in a Danish population. METHODS: This is a cross-sectional study including 1,163 children with CP aged 0-15 years, registered in the Danish National Cerebral Palsy Registry between 2017 and 2019. Prevalence of knee contracture was estimated, and logistic regression analysis was applied with results presented as odds ratio (OR) with 95% confidence intervals (CI). RESULTS: A total of 511 children with CP had knee contracture resulting in a prevalence of 44%. Age groups 4-6 years (OR: 1.73, CI: 1.19; 2.52), 7-9 years (OR: 1.85, CI: 1.29; 2.66) and 10-12 years (OR: 2.12, CI: 1.39; 3.24) were significantly associated with a higher prevalence of knee contractures compared to age group 0-3 years. Knee contractures were significantly more frequent at GMFCS levels IV (OR: 1.9, CI: 1.21; 2.97) and V (OR: 3.62, CI: 2.36; 5.55) compared to level I. Knee contractures were not associated with higher levels of MAS. CONCLUSIONS: Knee contractures are highly prevalent and significantly associated with high levels of GMFCS and increased age until 12 years, but not with high levels of spasticity in children with CP in Denmark.

Risk factors for the postoperative bladder neck contracture in patients with small-volume prostatic hyperplasia.

OBJECTIVE: This study was to explore the risk factors for postoperative bladder neck contracture (BNC) after transurethral operation of prostate in patients with small-volume prostatic obstruction. METHODS: Clinicopathologic data at our center from February 2016 to January 2020 were retrospectively collected and analyzed. Clinicopathological characteristics between patients with and without BNC were compared. Multivariate logistic regression was used to determine the risk factors for postoperative BNC. RESULTS: There were a total of 39 patients (8.53%) with postoperative BNC. Multivariate logistic regression analysis demonstrated that preoperative bladder neck diameter (BND), intravesical prostatic protrusion (IPP), surgical methods (transurethral resection of prostate (TURP)/anatomical endoscopic enucleation of the prostate (AEEP)), and postoperative urinary tract infection (UTI) were independent risk factors for postoperative BNC in patients with small-volume prostatic obstruction (P < 0.05). The incidence of postoperative BNC in patients undergoing AEEP was significantly decreased compared with those undergoing TURP. The optimal cut-off value of preoperative IPP was 6.10 mm while the optimal cut-off value of preoperative BND was 2.52 cm. CONCLUSIONS: Larger preoperative bladder neck and higher preoperative IPP lead to decreased incidence of postoperative BNC in patients with small-volume prostatic obstruction. Active management of postoperative UTI could effectively prevent the occurrence of postoperative BNC. Compared with TURP, complete AEEP would contribute to reduce BNC in patients with small-volume prostatic obstruction.

Risk Factors for Capsular Contracture in Alloplastic Reconstructive and Augmentation Mammaplasty: Analysis of the National Surgical Quality Improvement Program (NSQIP) Database.

BACKGROUND: Capsular contracture is the most common complication of breast augmentation and reconstruction. It occurs in up to 45% of patients and is theorized to occur secondary to an immune reaction. It can lead to pain, dissatisfaction with aesthetic outcomes, and reoperation. The gold standard for management is capsulectomy. Prior similar studies are limited by narrow inclusion criteria, single-surgeon analysis, small sample size, or univariate analysis. The goal of the following study is to prospectively identify possible risk factors for capsular contracture using a national database. METHODS: A retrospective review was conducted utilizing the National Surgical Quality Improvement Program (NSQIP) Database of prospectively collected data of patients undergoing periprosthetic and/or total capsulectomy for capsular contracture from 2013 to 2016. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for variables using a multivariable binary logistic regression model. RESULTS: A total of 6547 patients underwent reconstructive or augmentation mammaplasty with a prosthetic implant, out of which 2543 (39%) underwent capsulectomy. Capsular contracture was more likely in older (OR: 1.10, 95% CI: 1.09-1.10, p<.001), overweight (OR: 1.12, 95% CI: 1.10-1.13, p<.001), and cancer patients (OR: 7.71, 95% CI: 2.22-28.8, p=0.001). Wound infection was associated with capsulectomy (OR: 6.69, 95% CI: 1.74-25.8, p<.001). CONCLUSION: These identified risk factors should be comprehensively addressed with patients during the informed consent process before breast augmentation or reconstruction with implants.

Prevalence and Severity of Burn Scars in Rural Mozambique.

BACKGROUND: Burn injuries are common in low- and middle-income countries (LMICs) and their associated disability is tragic. This study is the first to explore burn scars in rural communities in Mozambique. This work also validated an innovate burn assessment tool, the Morphological African Scar Contractures Classification (MASCC), used to determine surgical need. METHODS: Using a stratified, population-weighted survey, the team interviewed randomly selected households from September 2012 to June 2013. Three rural districts (Chókwè, Nhamatanda, and Ribáuè) were selected to represent the southern, central and northern regions of the country. Injuries were recorded, documented with photographs, and approach to care was gathered. A panel of residents and surgeons reviewed the burn scar images using both the Vancouver Scar Scale and the MASCC, a validated visual scale that categorizes patients into four categories corresponding to levels of surgical intervention. RESULTS: Of the 6104 survey participants, 6% (n = 370) reported one or more burn injuries. Burn injuries were more common in females (57%) and most often occurred on the extremities. Individuals less than 25 years old had a significantly higher odds of reporting a burn scar compared to people older than 45 years. Based on the MASCC, 12% (n = 42) would benefit from surgery to treat contractures. CONCLUSION: Untreated burn injuries are prevalent in rural Mozambique. Our study reveals a lack of access to surgical care in rural communities and demonstrates how the MASCC scale can be used to extend the reach of surgical assessment beyond the hospital through community health workers.

Sequence of flexion contracture development in the lower limb: a longitudinal analysis of 1,071 children with cerebral palsy.

BACKGROUND: To prevent severe contractures and their impact on adjacent joints in children with cerebral palsy (CP), it is crucial to treat the reduced range of motion early and to understand the order by which contractures appear. The aim of this study was to determine how a hip-knee or ankle contracture are associated with the time to and sequence of contracture development in adjacent joints. METHODS: This was a longitudinal cohort study of 1,071 children (636 boys, 435 girls) with CP born 1990 to 2018 who were registered before 5 years of age in the Swedish surveillance program for CP and had a hip, knee or ankle flexion contracture of ≥ 10°. The results were based on 1,636 legs followed for an average of 4.6 years (range 0-17 years). The Cox proportional-hazards model adjusted for Gross Motor Function Classification System (GMFCS) levels I-V was used to compare the percentage of legs with and without more than one contracture. RESULTS: A second contracture developed in 44% of the legs. The frequency of multiple contractures increased with higher GMFCS level. Children with a primary hip or foot contracture were more likely to develop a second knee contracture. Children with a primary knee contracture developed either a hip or ankle contracture as a second contracture. CONCLUSIONS: Multiple contractures were associated with higher GMFCS level. Lower limb contractures appeared in specific patterns where the location of the primary contracture and GMFCS level were associated with contracture development in adjacent joints.

Complications and satisfaction in transwomen receiving breast augmentation: short- and long-term outcomes.

BACKGROUND: To achieve long-term improvement in health care of transgender women, it is necessary to analyze all aspects of gender-confirming surgery, especially the relation of risks and benefits occurring in these procedures. While there are many studies presenting data on the urologic part of the surgery, there are just few data about complications and satisfaction with breast augmentation. METHODS: This is a retrospective study using parts of the BREAST-Q Augmentation Questionnaire and additional questions for symptoms of capsular contracture and re-operations and analyzing archived patient records of all transwomen which were operated at University Hospital Essen from 2007 to 2020. RESULTS: 99 of these 159 patients (62%) completed the questionnaire after a median time of 4 years after surgery. Breast augmentation led to re-operations due to complications in 5%. The rate of capsular contracture (Baker Grad III-IV) in this population was 3%. Most patients (75%) rated high scores of satisfaction with outcome (more than 70 points) and denied to have restrictions due to their implants in their everyday life. All patients reported an improvement in their quality of life owing to breast augmentation. CONCLUSION: Breast augmentation by inserting silicon implants is a safe surgical procedure which takes an important part in reducing gender dysphoria.

Associations among quality of life, activities, and participation in elderly residents with joint contractures in long-term care facilities: a cross-sectional study.

BACKGROUND: Joint contractures and degenerative osteoarthritis are the most common joint diseases in the elderly population, can lead to limited mobility in elderly individuals, can exacerbate symptoms such as pain, stiffness, and disability, and can interfere with social participation and quality of life, thus affecting mental health. However, relevant studies on this topic are very limited. This study describes the associations of joint contracture categories and sites in elderly residents in long-term care facilities with their quality of life, activities, and participation. METHODS: Elderly individuals with joint contractures who were residents in long-term care facilities were recruited. The World Health Organization (WHO) Quality of Life and the WHO Disability Assessment Schedule 2.0 were used to survey the participants. Correlations, multiple linear regressions, and multiple analyses of variance, with joint contractures as the response variable, were used in the statistical analysis. RESULTS: The final statistical analysis included 232 participants. The explanatory power of contracture sites on activities and participation had a moderate strength of association (η2 = .113). Compared with elderly residents with joint contractures and osteoarthritis isolated to the upper limbs, those with joint contractures and osteoarthritis in both the upper and lower limbs had significantly worse activity and participation limitations. No significant differences in activity and participation were found between elderly residents with joint contractures affecting only the upper limbs and those with joint contractures affecting only the lower limbs (F1,226 = 2.604 and F1,226 = 0.674, nonsignificant). Osteoarthritis had the greatest impact on activity limitations and participation restrictions among elderly residents with joint contractures affecting both the upper and lower limbs (F1,226 = 6.251, p = .014). CONCLUSIONS: Elderly residents in long-term care facilities belonging to minority groups, with a history of stroke, and with osteoarthritis are at a high risk of developing activity limitations and participation restrictions. Moreover, compared with other contraction sites, regardless of osteoarthritis, joint contractures affecting both the upper and lower limbs were associated with the greatest activity limitations and participation restrictions. TRIAL REGISTRATION: This study has been registered in the Chinese Clinical Trial Registry, registration number and date: ChiCTR2000039889 (13/11/2020).

Large flexion contracture angle predicts tight extension gap during navigational posterior stabilized-type total knee arthroplasty with the pre-cut technique: a retrospective study.

BACKGROUND: This study aimed to determine the predictors of tight extension gap (EG) compared with the flexion gap (FG) during navigational posterior stabilized-type total knee arthroplasty using the pre-cut technique. METHODS: Nineteen patients with tight EG (defined as FG-EG ≥2 mm after pre-cut; group T) and 84 patients with an approximately equal gap (defined as FG-EG = 0-1 mm after pre-cut; group E) were enrolled. Medial tibial slope angle, hip knee ankle angle, flexion contracture angle, and active maximum flexion angle were compared between the two groups. RESULTS: The multivariate logistic regression model indicated that the probability of tight EG increased with flexion contracture angle (odds ratio, 1.13; 95% confidence interval 1.05-1.20; P ≤ 0.001). According to the receiver operating characteristic analysis, the flexion contracture angle cut-off value associated with tight EG was 15.0° (sensitivity, 85%; specificity, 78%). CONCLUSION: This study demonstrated that a large flexion contracture angle (cut-off 15.0°) was associated with tight EG after pre-cut osteotomy during posterior stabilized-type total knee arthroplasty. Awareness of this risk factor may help improve preoperative predictability of tight EGs and preparedness for additional procedures, such as soft tissue release or capsulotomy, to correct them. LEVEL OF EVIDENCE: Level III.

The degree of joint range of motion limitations after burn injuries during recovery.

INTRODUCTION: The aim of this study was to determine the degree of ROM limitations of extremities, joints and planes of motion after burns and its prevalence over time. METHOD: The database of a longitudinal multicenter cohort study in the Netherlands (2011-2012) was used. From patients with acute burns involving the neck, shoulder, elbow, wrist, hip, knee and ankle joints that had surgery, ROM of 17 planes of motion was assessed by goniometry at 3, 6 weeks, 3-6-9 and 12 months after burns and at discharge. RESULTS: At 12 months after injury, 12 out of 17 planes of motion demonstrated persistent joint limitations. The five unlimited planes of motion were all of the lower extremity. The most severely limited joints at 12 months were the neck, ankle, wrist and shoulder. The lower extremity was more severely limited in the early phase of recovery whereas at 12 months the upper extremity was more severely limited. CONCLUSION: The degree of ROM limitations and prevalence varied over time between extremities, joints and planes of motion. This study showed which joints and planes of motion should be watched specifically concerning the development of scar contracture.

The development of burn scar contractures and impact on joint function, disability and quality of life in low- and middle-income countries: A prospective cohort study with one-year follow-up.

OBJECTIVE: The aim of this study was to assess the development of burn scar contractures and their impact on joint function, disability and quality of life in a low-income country. METHODS: Patients with severe burns were eligible. Passive range of motion (ROM) was assessed using lateral goniometry. To assess the development of contractures, the measured ROM was compared to the normal ROM. To determine joint function, the normal ROM was compared to the functional ROM. In addition, disability and quality of life (QoL) were assessed. Assessments were from admission up to 12 months after injury. RESULTS: Thirty-six patients were enrolled, with a total of 124 affected joints. The follow-up rate was 83%. Limited ROM compared to normal ROM values was observed in 26/104 joints (25%) at 12 months. Limited functional ROM was observed in 55/115 joints (48%) at discharge and decreased to 22/98 joints (22%) at 12 months. Patients who had a contracture at 12 months reported more disability and lower QoL, compared to patients without a contracture (median disability 0.28 versus 0.17 (p = 0.01); QoL median 0.60 versus 0.76 (p = 0.001)). Significant predictors of developing joint contractures were patient delay and the percentage of TBSA deep burns. CONCLUSION: The prevalence of burn scar contractures was high in a low-income country. The joints with burn scar contracture were frequently limited in function. Patients who developed a contracture reported significantly more disability and lower QoL. To limit the development of burn scar contractures, timely access to safe burn care should be improved in low-income countries.

Factors Associated with Development of New Joint Contractures in Long-Term Care Residents.

OBJECTIVE: Limb contractures are associated with poor outcomes and quality of life in long-term care (LTC) residents. This study examined the rate of developing new joint contracture in the LTC residents and associated risk factors to formulate effective interventions in this critical but understudied area. DESIGN: This is an observational study with data obtained from the Hong Kong Longitudinal Study on LTC Residents between 2005 and 2016. SETTING AND PARTICIPANTS: Trained assessors (nurses, social workers, and therapists) used the Minimum Data Set Resident Assessment Instrument (MDS-RAI 2.0) to collect the data of the residents from 9 residential LTC facilities. MEASURES: Limb contractures were defined as a functional limitation in the range of motion involving the upper or lower limbs. Primary outcomes included annual prevalence of joint contractures and factors that were associated with the development of new joint contractures. RESULTS: We analyzed the data for 1914 older residents (674 males, mean age 83.4 years). During the first 5 years since admission, the annual prevalence of upper limb contractures increased from 29.8% to 36.5%, and lower limb contractures increased from 41.5% to 57.4%. Overall, the increment of the prevalence rate of joint contractures per year ranged from 0.7% to 3.2% for the upper limbs and 0.3% to 6.0% per year for the lower limbs. Impaired mobility, presence of neurologic diseases, and older age were the leading independent risk factors for the development of new joint contractures. CONCLUSIONS AND IMPLICATIONS: Joint contractures are highly prevalent among residents admitted to the LTC facilities, and many residents develop new contractures during the first 5 years of their admission. Immobility appears to be the main modifiable risk factor. Further studies are needed to identify potential strategies to prevent new contractures in this vulnerable group.

Update on the Practice of Splinting During Acute Burn Admission From the ACT Study.

Burn scar contracture (BSC) is a common pathological outcome following burn injuries, leading to limitations in range of motion (ROM) of affected joints and impairment in function. Despite a paucity of research addressing its efficacy, static splinting of affected joints is a common preventative practice. A survey of therapists performed 25 years ago showed a widely divergent practice of splinting during the acute burn injury. We undertook this study to determine the current practice of splinting during the index admission for burn injuries. This is a review of a subset of patients enrolled in the Burn Patient Acuity Demographics, Scar Contractures and Rehabilitation Treatment Related to Patient Outcome Study (ACT) database. ACT was an observational multicenter study conducted from 2010 to 2013. The most commonly splinted joints (elbow, wrist, knee, and ankle) and their seven motions were included. Variables included patients' demographics, burn variables, rehabilitation treatment, and hospital course details. Univariate and multivariate analysis of factors related to splinting was performed. P < .05 was significant. Thirty percent of the study population (75 patients) underwent splinting during their hospitalization. Splinting was associated with larger burns and increased injury severity on the patient level and increased involvement with burns requiring grafting in the associated cutaneous functional unit (CFU) on the joint level. The requirement for skin grafting in both analyses remained independently related to splinting, with requirement for grafting in the associated CFU increasing the odds of splinting six times (OR = 6.0, 95% CI = 3.8-9.3, P < .001). On average, splinting was initiated about a third into the hospital length of stay (LOS, 35 ± 21% of LOS) and splints were worn for 50% (50 ± 26%) of the LOS. Joints were splinted for an average 15.1 ± 4.8 hours a day. The wrist was most frequently splinted joint being splinted with one third of wrists splinted (30.7%) while the knee was the least frequently splinted joint with 8.2% splinted. However, when splinted, the knee was splinted the most hours per day (17.6 ± 4.8 hours) and the ankle the least (14.4 ± 4.6 hours). Almost one third had splinting continued to discharge (20, 27%). The current practice of splinting, especially the initiation, hours of wear and duration of splinting following acute burn injury remains variable. Splinting is independently related to grafting, grafting in the joint CFU, larger CFU involvement and is more likely to occur around the time of surgery. A future study looking at splinting application and its outcomes is warranted.

[Predictors of bladder neck contracture after transurethral procedure on the prostate].

The development and widespread implementation of modern endourological procedures for the treatment of benign prostatic hyperplasia (BPH) has led to a significant reduction in postoperative complications, but these interventions are associated to an increase of bladder neck contracture (BNC) rate. Various data on the frequency, pathogenesis, and risk factors for the development of BNC after endourological interventions are presented in the literature review. The prevalence of BNC after transurethral procedures depending on the type of energy used reaches up to 10%. Risk factors of BNC included the presence of chronic prostatitis and urinary tract infections, as well as small volume BPH. The age, cardiovascular diseases, type 2 diabetes, obesity, and a long-term smoking are considered as additional risk factors. A detailed study of the risk factors for BNC will further minimize BNC rate after transurethral procedures, thus improving the quality of life of patients.
