Total Knee Arthroplasty in Patients with Cerebral Palsy: A Large Database Analysis

Cerebral palsy (CP) is a neurodevelopmental condition that can result in altered gait biomechanics, joint dysfunction, and imbalance. The complications associated with total knee arthroplasty (TKA) in patients with CP have not yet been well described. Therefore, our analysis sought to compare the 90-day and 2-year complications following TKA in patients with and without CP. The PearlDiver Mariner database was utilized to identify patients with CP undergoing primary TKA between 2010 and 2020. This cohort was matched 1:4 to a control cohort without neurodegenerative disorders based on age, sex, Elixhauser Comorbidity Index (ECI), tobacco use, obesity, and diabetes. A total of 3,257 patients (657 CP patients 2,600 controls) were included in our final analysis. A multivariable logistic regression analysis was utilized to determine the risk of CP on medical and surgical complications at 90 days and all-cause revision rates at 2 years. Patients with CP had an increased risk of acute kidney injury (odds ratio [OR]: 1.66; 95% confidence interval [CI]: 1.07-2.5; p = 0.019), pneumonia (OR: 5.63; 95% CI: 3.69-8.67; p < 0.001), urinary tract infection (OR: 5.01; 95% CI: 3.85-6.52; p < 0.001), and transfusion (OR: 2.21; 95% CI: 1.50-3.23; p < 0.001). CP patients additionally had a higher incidence of emergency department (ED) visits (OR: 5.24; 95% CI: 3.76-7.32; p < 0.001) and readmissions (OR: 5.24; 95% CI: 2.57-4.96; p < 0.001). There were no differences in rates of periprosthetic joint infection (PJI; OR: 1.23; 95% CI: 0.69-2.10; p = 0.463), surgical site infection (SSI; OR: 0.51; 95% CI: 0.12-1.46; p = 0.463), and reoperation (OR: 1.35; 95% CI: 0.71-2.43; p = 0.339) at 90 days postoperatively. The all-cause revision rates at 2 years were comparable (OR: 1.02; 95% CI: 0.67-1.51; p = 0.927). In this database review, we found that CP patients have a higher risk of medical complications in the acute postoperative period following TKA. The 90-day surgical complication and 2-year revision rates in CP patients were comparable to matched controls.

The assessment and management of voiding dysfunction in adults living with cerebral palsy

PURPOSE

Improvements in life expectancy have resulted in an increasing number of adults with cerebral palsy, of which over a third will have neurogenic lower urinary tract dysfunction (NLUTD). This review explores urinary dysfunction in adults with cerebral palsy.

METHODS

Relevant literature on NLUTD in adults with cerebral palsy was identified using an unrestricted search of PubMed.

RESULTS

Urinary incontinence is the most common complaint, often accompanied by frequency and urgency. Special consideration should be given to women and in those with worse motor or cognitive dysfunction as they have been shown to have more severe urologic symptoms. NLUTD can have significant morbidity and impact quality of life. Hospital admission, urinary tract infections, and hydronephrosis are common urologic complications, with poor urinary function associated with decreased quality of life (QOL). Neurogenic detrusor overactivity is the most common urodynamic abnormality, with elevated detrusor leak point pressure and reduced bladder capacity. Detrusor sphincter dyssynergy is present in some patients and maybe secondary to generalized spasticity or incomplete upper motor neuron injury. Elevated bladder capacity is also present in a portion of patients, and becomes particularly relevant in adults as a result of increased spasticity of the urinary sphincter. Conservative management like functional toileting strategies, medications, and incontinence aids are successful in most patients. Medical management with anticholinergics is well described, and frequently the only intervention required, particularly in children. Intermittent clean catheterization has mixed results with this population, as its efficacy is limited by pelvic spasticity and patient factors. Surgical intervention, while often successful, should be restricted to select patients, as it is associated with significant morbidity in this population.

CONCLUSION

Management of NLUTD in adults with CP involves conservative management, medications, and in rare cases surgical intervention.

Effect of neurodevelopmental treatment in children with congenital Zika syndrome: A pilot study

AIM

To evaluate the effects of neurodevelopmental treatment (NDT) in children with congenital Zika syndrome (CZS).

METHODS

This prospective, interventional cohort study involved children with CZS undergoing follow-up at a specialist centre in northeastern Brazil. The duration of the proposed NDT protocol was 1 year, with 45-min sessions delivered one to five times weekly. Motor function, weight, height, head circumference and the incidence of comorbidities were evaluated in children before protocol initiation and then at 3, 6 and 12 months of treatment.

RESULTS

Thirty children were evaluated (age mean 30.1 ± 3 months). Motor function improved from baseline to 6 months (P = 0.001). No difference in weight and head circumference z-score (P = 0.51 and P = 0.29, respectively), but an increase in height z-score (P < 0.001) was observed over the evaluation period. There was a reduction in the incidence of upper respiratory tract infections, pneumonia and urinary tract infections over the follow-up period.

CONCLUSIONS

NDT proved to be a viable treatment approach that can improve motor function and reduce the incidence of comorbidities in children with CZS, while having no harmful effects on their growth.

Microbiological Characterisation of Community-Acquired Urinary Tract Infections in Bagamoyo, Tanzania: A Prospective Study

Urinary tract infections (UTIs) are among the most common infections in sub-Saharan Africa, but microbiological data to guide treatment decisions are limited. Hence, we investigated the bacterial aetiology and corresponding antimicrobial susceptibility patterns in outpatients with UTIs in Bagamoyo, Tanzania. Urine samples from symptomatic individuals were subjected to microbiological examinations for bacterial species identification using conventional methods and disc diffusion-based resistance testing. Subsequently, urine samples were transferred to Germany for confirmatory diagnostics using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry and automated resistance testing. Overall, 104 out of 270 (38.5%) individuals had a positive urine culture and 119 putative pathogens were identified. The most frequently detected bacteria were Escherichia coli (23%), Klebsiella spp. (7%), Enterobacter cloacae complex (3%) and Staphylococcus aureus (2%). E. coli isolates showed high resistance against cotrimoxazole (76%), ampicillin (74%), piperacillin (74%) and fluoroquinolones (37%), but widespread susceptibility to meropenem (100%), fosfomycin (98%), piperacillin/tazobactam (97%) and amoxicillin/clavulanic acid (82%). The agreement between E. coli susceptibility testing results in Tanzania and Germany was ≥95%, except for piperacillin/tazobactam (89%) and ciprofloxacin (84%). Given the considerable resistance to frequently prescribed antibiotics, such as cotrimoxazole and fluoroquinolones, future research should explore the potential of oral alternatives (e.g., fosfomycin) for the treatment of UTIs in Tanzania.

Routine Screening and Treatment of Urinary Tract Infection May Be Justified in Children and Adolescents with Cerebral Palsy: A Systematic Review

Context: Children and adolescents with cerebral palsy may present with lower urinary tract dysfunction which increases their risk for urinary tract infection (UTI). Whereas few studies reported low prevalence rates of UTI in these patients, several studies documented high prevalence rates. Thus, it appears there is no unanimity about the burden of UTI in affected children and adolescents to justify routine screening and treatment of the infection. This systematic review aims to determine the risk and pooled prevalence rate of UTI in children and adolescents with cerebral palsy. Evidence Acquisition: Using appropriate descriptors, we searched the PubMed and Google Scholar databases. Eligible papers were primary studies published in English language: reporting an association between cerebral palsy and UTI or UTI prevalence in children and adolescents with cerebral palsy and healthy comparators, with a clear definition of UTI and cerebral palsy. We assessed the quality of included studies with the Newcastle-Ottawa Scale (NOS) and resolved inter-rater discrepancies by consensus. We independently retrieved relevant data from these studies using a preconceived data-extraction form. We analyzed the aggregate data on UTI prevalence in these pediatric patients, using the log odds ratio (OR) at 95% confidence interval as the summary estimate. Results: Of the seven included studies, only two (28.6%) were case-control studies, while five (71.4%) were cross-sectional studies. There was no uniform definition of UTI in these studies. Prevalence rates varied widely from as low as 2.2% to as high as 56.7%. The mean UTI prevalence rate estimated for six of the included studies was 31.8%. The log OR at 95% CI computed for the case-control studies was 10.9 (95% CI: 9.0, 12.9). Conclusions: The prevalence and risk of UTI in children and adolescents with cerebral palsy are significantly high. Routine screening and treatment for UTI may be justified in these pediatric patients. We however recommend more prospective case-control studies to strengthen the current evidence of the high UTI burden in these patients.
