The association of COVID-19 pandemic with the increase of sinogenic and otogenic intracranial infections in children: a 10-year retrospective comparative single-center study.

OBJECTIVE: Otitis media and sinusitis are common childhood infections, typically mild with good outcomes. Recent studies show a rise in intracranial abscess cases in children, raising concerns about a link to COVID-19. This study compares a decade of data on these cases before and after the pandemic. METHODS: This retrospective comparative analysis includes pediatric patients diagnosed with otitis media and sinusitis, who later developed intracranial abscesses over the past decade. We collected comprehensive data on the number of cases, patient demographics, symptoms, treatment, and outcomes. RESULTS: Between January 2013 and July 2023, our center identified 10 pediatric patients (median age 11.1years, range 2.2-18.0 years, 60% male) with intracranial abscesses from otitis media and sinusitis. Of these, 7 cases (70%, median age 9.7 years, range 2.2-18.0 years) occurred since the onset of the COVID-19 pandemic, while the remaining 3 cases (30%, median age 13.3 years, range 9.9-16.7 years) were treated before the pandemic. No significant differences were found in otolaryngological associations, surgical interventions, preoperative symptoms, lab findings, or postoperative antibiotics between the two groups. All patients showed positive long-term recovery. CONCLUSION: This study reveals 5-fold increase of pediatric otogenic and sinogenic intracranial abscess cases in the last three-years since the onset of the COVID-19 pandemic. While further investigation is needed, these findings raise important questions about potential connections between the pandemic and the severity of otitis media and sinusitis complications in children. Understanding these associations can improve pediatric healthcare management during infectious disease outbreaks.

Decoding pediatric spinal tumors: a single-center retrospective case series on etiology, presentation, therapeutic strategies, and outcomes.

INTRODUCTION: Spinal tumors (ST) often result in dire prognosis, carrying risks such as permanent paralysis, sensory loss, and sphincter dysfunction. Data on their incidence and etiology in pediatric populations are markedly scant. Our study investigates the etiology, clinical manifestation, treatment, and outcomes of pediatric ST. METHODS: We conducted a retrospective review of our institutional pediatric oncology and neurosurgery database, examining 14 patients under 18 years admitted with ST due to oncological diseases since 2005. We analyzed the clinical presentations, evaluations, molecular diagnostics and treatments for these patients. RESULTS: The study spanned 15 years and included 14 pediatric patients, each diagnosed with distinct spinal tumor entity. The mean patient age was approximately 19.6 ± 10.1 months. Severe axial pain along the vertebral column was observed in 13 patients, while acute neurological deterioration manifested in 7 patients. As a first-line intervention, 13 patients underwent decompressive surgery through laminectomy and tumor resection, and only one patient received chemotherapy solely. Before surgery, seven patients were unable to walk; post-surgery, six of them regained their ability to ambulate. The diagnosis encompassed a range of neoplasms: two instances of Ewing sarcoma, 3 instances of teratoma, one case presenting an atypical teratoid Rhabdoid tumor, two instances each of low-grade astrocytoma and neuroblastoma, and single instances of ependymoma, meningioma, rhabdomyosarcoma, and embryonal tumors with multilayered rosettes (ETMRs). Three patients succumbed two years after initiating therapy. CONCLUSION: Despite their rarity, intraspinal tumors in pediatric patients pose substantial therapeutic challenges. The intertwined complexities of the disease entity and the patient's neurological status demand swift initiation of an individualized therapeutic strategy. This crucial step helps optimize outcomes for this patient cohort, who frequently grapple with debilitating health conditions. Inclusion of these patients within a registry is mandatory to optimize treatment outcomes due to their rarity in pediatric population.

Easing Panic: The Effect of an Online Psychoeducational Program on Panic Symptoms, Anxiety, and Quality of Life Among People Experiencing Panic Attacks.

Panic attacks (PAs) are intense episodes of anxiety with severe physical symptoms that can impair an individual's social and occupational functions. Psychoeducation, a structured educational intervention, aims to improve various health aspects, including mental disorders. Delivering psychoeducation via the Internet can overcome barriers to accessing mental health treatment. This study examined the effectiveness of online psychoeducation on panic symptoms, anxiety, and quality of life (QOL) among people experiencing PAs. In this quasi-experimental design, 157 participants with PAs were recruited, and 136 eligible participants were allocated to treatment and control groups. The treatment group received an eight-session online psychoeducational program over 8 weeks, while the control group received reading materials. Outcome variables, including panic symptoms, anxiety, and QOL, were measured at baseline, 1-week post-intervention, and at 8-week follow-up using the Panic Disorder Dimensional (PD-D) scale, the Generalized Anxiety Disorder (GAD-7) scale, and the World Health Organization Quality of Life-BREF (WHOQOL-BREF), respectively. In the treatment group, the split-plot ANOVA showed a significant reduction in panic symptoms [F(1, 98) = 18.86, p < 0.01] and anxiety [F(1, 98) = 18.241, p < 0.01] compared to the control group. However, the intervention did not significantly affect QOL [F(1, 98) = 0.278, MSE = 153.007, p > 0.05]. The online psychoeducational program effectively reduced panic symptoms and anxiety levels but did not significantly impact QOL. Internet-based interventions, including psychoeducation, can improve access to mental health treatment, potentially reducing the treatment gap and enhancing overall mental health outcomes.

Heidelberg ETV score to assess success of ETV in patients with occlusive hydrocephalus: a retrospective single-center study.

In aqueduct stenosis, pressure difference below and above level of obstruction leads to bulging of third ventricular floor (TVF) and lamina terminalis (LT). Endoscopic third ventriculocisternostomy (ETV) is the standard treatment in these patients. We tried to assess success of ETV depending on those two radiological changes in aqueduct stenosis. We implemented "Heidelberg ETV score" retrospectively to assess the state of TVF as well as LT in same manner in midsagittal MR image. Every patient had a preoperative, direct, 3-months and one-year postoperative score from -2 to + 2. We correlated the scores to clinical course to decide whether the score is reliable in defining success of ETV. Between 2017-2021, 67 (mean age 25.6 ± 23.9y) patients treated with ETV were included. Success rate of primary and Re-ETVs was 91% over 46.8 ± 19.0 months. A marked shift of score to the left after surgery in success group was noticed through the distribution of score immediate postoperative, 3-months later; 70.2% showed (+ 2) before surgery, 38.9% scored (0) after surgery and 50.9% showed further score drop to (-1) 3 months later, p < 0.001. In cases of failure, there was initial decrease after surgery followed by increase with ETV-failure (mean time to failure: 7.2 ± 5.7 months) in 100%. Significant difference was noticed in Heidelberg score at postoperative 1-year- and failure-MRI follow-up between two groups, p < 0.001. Heidelberg score describes anatomical changes in third ventricle after ETV and can serve in assessment of MR images to define success of the procedure in patients with aqueduct stenosis.

ACDF versus corpectomy in octogenarians with cervical epidural abscess: early complications and outcomes with 2 years of follow-up.

PURPOSE: Cervical spinal epidural abscess (CSEA) is a rare condition, manifesting as rapid neurological deterioration and leading to early neurological deficits. Its management remains challenging, especially in patients older than 80 years. Therefore, we aimed to compare the clinical course and determine morbidity and mortality rates after anterior cervical discectomy and fusion (ACDF) versus corpectomy in octogenarians with ventrally located CSEA at two levels. METHODS: In this single-center retrospective review, we obtained the following from electronic medical records between September 2005 and December 2021: patient demographics, surgical characteristics, complications, hospital clinical course, and 90-day mortality rate. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). RESULTS: Over 16 years, 15 patients underwent ACDF, and 16 patients underwent corpectomy with plate fixation. Between the two groups, patients who underwent corpectomy had a significantly poorer baseline reserve (9.0 ± 2.6 vs. 10.8 ± 2.7; p = 0.004) and had a longer hospitalization period (16.4 ± 13.1 vs. 10.0 ± 5.3 days; p = 0.004) since corpectomy lasted significantly longer (229.6 ± 74.9 min vs. 123.9 ± 47.5 min; p < 0.001). Higher in-hospital and 90-day mortality and readmission rates were observed in the corpectomy group, but the difference was not statistically significant. Both surgeries significantly improved blood infection parameters and neurological status at discharge. Revision surgery due to pseudoarthrosis was required in two patients after corpectomy. CONCLUSIONS: We showed that both ACDF and corpectomy for ventrally located CSEA can be considered as safe treatment strategies for patients aged 80 years and above. However, the surgical approach should be carefully weighed and discussed with the patients and their relatives.

Programmable (proSA®) vs. fixed (SHUNTASSISTANT®) gravitational valves in pediatric patients with hydrocephalus: a 16-year retrospective single-center comparative study with biomechanical analysis.

PURPOSE: In pediatric hydrocephalus (HC) treatment, programmable gravitational valves offer greater flexibility to manage overdrainage during children's growth. However, it remains unclear whether these devices provide better outcomes rather than their precursors. The study assessed the benefit from programmability of gravitational valve, i.e., programmable-SHUNTASSISTANT (proSA®) vs. SHUNTASSISTANT® (SA®). METHODS: Clinical records and imaging of pediatric patients with hydrocephalus of non-tumoral etiology treated with fixed (SA®) or programmable (proSA®) gravitational valves between January 2006 and January 2022 were analyzed in a retrospective single-center study. Valve survival was compared in relation to age and etiology. Lately explanted valves received biomechanical analysis. RESULTS: A total of 391 gravitational valves (254 SA® and 137 proSA®) were inserted in 244 patients (n = 134 males). One hundred thirty-three SA® (52.4%) and 67 proSA® (48.9%) were explanted during a follow-up of 81.1 ± 46.3 months. Valve survival rate at 1 and 5 years with proSA® was 87.6% and 60.6% compared to 81.9% and 58.7% with SA®, with mean survival time 56.4 ± 35.01 and 51.4 ± 43.0 months, respectively (P = 0.245). Age < 2 years at implantation correlated with significantly lower valve survival rates (P < 0.001), while HC etiology showed no significant impact. Overdrainage alone accounted for more SA® revisions (39.8% vs. 3.1%, P < 0.001), while dysfunctions of the adjustment system represented the first cause of valve replacement in proSA® cohort (45.3%). The biomechanical analysis performed on 41 proSA® and 31 SA® showed deposits on the valve's internal surface in 97.6% and 90.3% of cases. CONCLUSION: Our comparative study between proSA® and SA® valves in pediatric HC demonstrated that both valves showed similar survival rates, regardless of etiology but only with young age at implantation. The programmability may be beneficial in preventing sequelae of chronic overdrainage but does not reduce need for valve revision and proSA® valve should be considered in selected cases in growing children older than 2 years.

Decompression only versus fusion in octogenarians with spinal epidural abscesses: early complications, clinical and radiological outcome with 2-year follow-up.

Despite increased life expectancy due to health care quality improvements globally, pyogenic vertebral osteomyelitis (PVO) treatment with a spinal epidural abscess (SEA) remains challenging in patients older than 80 years. We aimed to assess octogenarians for PVO prevalence with SEA and compare after-surgery clinical outcomes of decompression and decompression and instrumentation. A retrospective review of electronic medical records at a single institution was conducted between September 2005 and December 2020. Patient demographics, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). Over 16 years, 35 patients aged ≥80 years with PVO and SEA were identified. Eighteen patients underwent surgical decompression ("decompression group"), and 17 underwent surgical decompression with instrumentation ("instrumentation group"). Both groups had a CCI >6 (mean±SD, 8.9±2.1 vs. 9.6±2.7, respectively; p=0.065). Instrumentation group patients had a significantly longer hospital stay but no ICU stay. In-hospital and 90-days mortality rates were similar in both groups. The mean follow-up was 26.6±12.4 months. No further surgeries were performed. Infection levels and neurological status were improved in both groups at discharge. At the second-stage analysis, significant improvements in the blood infection parameters and the neurological status were detected in the decompression group. Octogenarians with PVO and SEA have a high adverse events risk after surgical procedures. Surgical decompression might contribute to earlier clinical recovery in older patients. Thus, the surgical approach should be discussed with patients and their relatives and be carefully weighed.

Spinal Meningioma Surgery in Octogenarians: Functional Outcomes and Complications over a 2-Year Follow-Up Period.

Background and Objectives: Population aging in industrial nations has led to an increased prevalence of benign spinal tumors, such as spinal meningiomas (SMs), in the elderly. The leading symptom of SM is local pain, and the diagnosis is confirmed after acute neurological decline. However, little is known about the optimal treatment for this frail patient group. Therefore, this study sought to assess the clinical outcome, morbidity, and mortality of octogenarians with SMs and progressive neurological decline undergoing surgery and to determine potential risk factors for complications. Materials and Methods: Electronic medical records dated between September 2005 and December 2020 from a single institution were retrieved. Data on patient demographics, neurological conditions, functional status, degree of disability, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Results: Thirty patients aged ≥80 years who were diagnosed with SMs underwent posterior decompression via laminectomy and microsurgical tumor resection. The patients presented with a poor baseline history (mean CCI 8.9 ± 1.6 points). Almost all SMs were located in the thoracic spine (n = 25; 83.3%). Progressive preoperative neurological decline was observed in 21/30 (n = 21; 70%) patients with McCormick Scores (mMCS) ≥3, and their mean motor score (MS) was 85.9 ± 12.3. in the in-hospital and 90-day mortality rates were 6.7% and 10.0%, respectively. The MS (93.6 ± 8.3) and mMCS (1.8 ± 0.9) improved significantly postoperatively (p < 0.05). The unique risk factor for complications was the severity of comorbidities. Conclusions: Decompressive laminectomy and tumor removal in octogenarians with progressive neurological decline improved patient functional outcomes at discharge. Surgery seems to be the "state of the art" treatment for symptomatic SMs in elderly patients, even those with poor preoperative clinical and neurologic conditions, whenever there is an acceptable risk from an anesthesiological point of view.

Etiology of diarrhea by multiplex polymerase chain reaction among young children in the United Arab Emirates: a case-control study.

BACKGROUND: Little is known about the etiology of childhood diarrhea in the United Arab Emirates (UAE) especially after the introduction of rotavirus vaccines. This study aimed to identify gastrointestinal pathogens in children with diarrhea (cases) and the carriage rate of these pathogens in asymptomatic children (controls). METHODS: Stool samples were collected from 203 cases and 73 controls who presented to two major hospitals in Al Ain city, UAE. Samples were analyzed with Allplex™ Gastrointestinal Full Panel Assay for common entero-pathogens. The association between diarrhea and the isolated pathogens was calculated in a multivariate logistic regression model. The adjusted attributable fractions (aAFs) were calculated for all pathogens significantly associated with cases. RESULTS: At least one pathogen was identified in 87 samples (42.8%) from cases and 17 (23.3%) from controls (P < 0.001). Rotavirus, norovirus GII and adenovirus were significantly more prevalent in cases. Their aAFs with 95% ci are 0.95 (0.64, 1.00) for rotavirus, 0.86 (0.38, 0.97) for norovirus GII and 0.84 (0.29, 0.96) for adenovirus. None of the 13 bacteria tested for were more commonly found in the cases than in controls. Cryptosporidium spp. were more significantly detected in cases than in controls. Co-infections occurred in 27.9% of the children. Viruses and parasites were significantly more likely to occur together only in the cases. CONCLUSIONS: Multiplex PCR revealed high positivity rates in both cases and controls which demand a cautious interpretation. Rotavirus remains the main childhood diarrhea pathogen in UAE. Effective strategies are needed to better control rotavirus and other causative pathogens.

Sustainable Development of Enhanced Luminescence Polymer-Carbon Dots Composite Film for Rapid Cd2+ Removal from Wastewater.

As a remedy for environmental pollution, a versatile synthetic approach has been developed to prepare polyvinyl alcohol (PVA)/nitrogen-doped carbon dots (CDs) composite film (PVA-CDs) for removal of toxic cadmium ions. The CDs were first synthesized using carboxymethylcellulose (CMC) of oil palms empty fruit bunch wastes with the addition of polyethyleneimine (PEI) and then the CDs were embedded with PVA. The PVA-CDs film possess synergistic functionalities through increasing the content of hydrogen bonds for chemisorption compared to the pure CDs. Optical analysis of PVA-CDs film was performed by ultraviolet-visible and fluorescence spectroscopy. Compared to the pure CDs, the solid-state PVA-CDs displayed a bright blue color with a quantum yield (QY) of 47%; they possess excitation-independent emission and a higher Cd2+ removal efficiency of 91.1%. The equilibrium state was achieved within 10 min. It was found that adsorption data fit well with the pseudo-second-order kinetic and Langmuir isotherm models. The maximum adsorption uptake was 113.6 mg g-1 at an optimal pH of 7. Desorption experiments showhe that adsorbent can be reused fruitfully for five adsorption-desorption cycles using 0.1 HCl elution. The film was successfully applied to real water samples with a removal efficiency of 95.34% and 90.9% for tap and drinking water, respectively. The fabricated membrane is biodegradable and its preparation follows an ecofriendly green route.

Quantitative testing of buprenorphine and norbuprenorphine to identify urine sample spiking during office-based opioid treatment.

BACKGROUND: Patients may spike urine samples with buprenorphine during office-based opioid treatment to simulate adherence to prescribed buprenorphine, potentially to conceal diversion of medications. However, routine immunoassay screens do not detect instances of spiking, as these would simply result in a positive result. The aim of this study was to report on the experience of using quantitative urine testing for buprenorphine and norbuprenorphine to facilitate the identification of urine spiking. METHODS: This is a retrospective chart review of 168 consecutive patients enrolled in outpatient buprenorphine treatment at an urban academic medical setting between May 2013 and August 2014. All urine samples submitted were subjected to quantitative urine toxicology testing for buprenorphine and norbuprenorphine. Norbuprenorphine-to-buprenorphine ratio of less than 0.02 were further examined for possible spiking. Demographic and clinical variables were also extracted from medical records. Clinical and demographic variables of those who did and did not spike their urines were compared. Statistically significant variables from the univariate testing were entered as predictors of spiking in a regression analysis. RESULTS: A total of 168 patients were included, submitting a total of 2275 urine samples. Patients provided on average 13.6 (SD = 9.9) samples, and were in treatment for an average 153.1 days (SD = 142.2). In total, 8 samples (0.35%) from 8 patients (4.8%) were deemed to be spiked. All of the samples suspected of spiking contained buprenorphine levels greater than 2000 ng/mL, with a mean norbuprenorphine level of 11.9 ng/mL. Spiked samples were submitted by 6 patients (75.0%) during the intensive outpatient (IOP) phase of treatment, 2 patients (25.0%) during the weekly phase, and none from the monthly phase. Regression analysis indicated that history of intravenous drug use and submission of cocaine-positive urine samples at baseline were significant predictors of urine spiking. CONCLUSIONS: Even though only a small number of patients were identified to have spiked their urine samples, quantitative testing may help identify urine spiking during office-based opioid treatment with buprenorphine.

Feasibility of Implementing Shared Medical Appointments (SMAs) for Office-Based Opioid Treatment With Buprenorphine: A Pilot Study.

BACKGROUND: Shared medical appointments (SMAs) are designed to improve patient satisfaction and increase access to treatment. In a typical SMA, 6-12 patients with similar diagnoses attend a group appointment with their health care providers, often lasting 60-120 minutes. All components of an individual visit are completed, and additional time is spent providing education and facilitating peer support. The aim of this study was to report on patient and program outcomes after implementation of SMA-based office-based opioid treatment with buprenorphine. METHODS: The study was conducted at a hospital-based outpatient psychiatric clinic that previously did not offer any office-based opioid treatment with buprenorphine. Demographic and clinical data (treatment retention, depression, anxiety, craving scores, and urine toxicology results) were extracted from the medical records. Patients were recruited to complete a survey assessing their experience. RESULTS: Ninety-three patients enrolled in the program, and 52.7% remained in treatment at 6 months. The proportion of aberrant opioid urine results, depression, anxiety, and craving decreased significantly from baseline to 6 months. Twenty-two patients completed the survey, who generally agreed that the SMA format allowed for more time with physicians, more support from peers, better coordination of care, and more predictable times for visits. CONCLUSIONS: Implementation of an SMA-based buprenorphine program was feasible, with treatment outcomes comparable to traditional models of care. More research is needed to explore the impact of SMA on buprenorphine treatment.

Impact of Initial Surgical Interventions on Empyema Outcomes: Insights From a Cohort Study in Yemen.

Purpose The study aimed to evaluate the effectiveness of different initial interventions, including thoracostomy drain tubes, open thoracotomy with decortication, and video-assisted thoracoscopic surgery (VATS) thoracoscopy in the management of empyema. Methods This prospective cohort study was conducted at two teaching hospitals in Sana'a, Yemen, over a two-year period from 2022 to 2024. The study included 40 patients diagnosed with empyema, categorized according to the type of initial intervention received. Demographic data, clinical presentation, imaging findings, intervention details, and outcomes were systematically collected and analyzed. Statistical analyses were performed to identify associations between demographic characteristics, empyema stage, intervention type, and treatment success. Results The study included 40 patients with a higher proportion of males (67.5%) than females (32.5%). The mean age was 47.1 years (standard deviation (SD): 12.85). The overall success rate of the initial interventions was 55%, with significant variation based on empyema stage, comorbidities, and intervention type. Stage I empyema had the highest success rate (80%), followed by Stage II (50%) and Stage III (27.3%), with a statistically significant difference (p = 0.034). Smoking history was identified as a significant negative predictor of success (p = 0.001). Higher pleural fluid pH was associated with better outcomes (p = 0.015). The most common complications were chest infections (20%) and bronchopleural fistulas (10%), with a mortality rate of 7.5%. Conclusion The empyema stage significantly affects the success rate, with early stages showing better outcomes. Early and appropriate intervention, particularly in later stages, is crucial for better outcomes. Effective management of postoperative complications is vital. This study highlights the need for early diagnosis and tailored interventions based on the empyema stage to improve patient outcomes. Future research should focus on larger multicenter studies to validate these findings and develop standardized treatment protocols.

Peripheral nerve stimulation for treatment of chronic headache: a case report.

Chronic daily headaches can be debilitating. Multiple treatments have been suggested with varying degrees of success. We present a case of a 27-year-old female with greater than ten years of chronic daily headaches. The patient was evaluated at the headache clinic where she was diagnosed with complex migraine with components of occipital neuralgia. Multiple medication regimens were tried without significant benefit. The patient also underwent bilateral occipital blocks along with trigger point injections of various muscles including the semispinalis capitis with significant but limited duration of benefit. After other treatments were unsuccessful, the patient was referred to the Pain Management Center and underwent a trial of peripheral nerve stimulation with significant pain relief without complications. She then proceeded with permanent implantation of the peripheral nerve stimulator with continued pain relief. This case demonstrates the utility of peripheral nerve stimulation for the treatment of refractory chronic daily headaches and should be part of our armamentarium.

Intracranial arachnoid cysts: What is the appropriate surgical technique? A retrospective comparative study with 61 pediatric patients.

Objective: Symptomatic intracranial arachnoid cysts (ACs) should be treated either through microsurgical (MS) or endoscopic surgical (ES) fenestration. Implantation of cysto-peritoneal shunt (CPS) system is another treatment option with decreasing indication. In our study, we compared the complication and revision rates between the three operative techniques in pediatric patients. Methods: We included patients below 18 years with symptomatic intracranial ACs operated between 2004 and 2021. Initial symptoms, location, complication rate, clinical and radiological improvement, postoperative events and revision rate were compared retrospectively. Results: Sixty-one patients; 33 (54.1%) MS operated (mean age 7.6 years), 18 (29.5%) ES operated (mean age 6.2 years) and 10 (16.4%) with CPS (mean age 3.0 years) were collected. The most common initial symptom was headache in 45.9%. 20 (32.8%) postoperative events were documented. The highest revision rate (60%) was seen in the CPS group compared to 33.3% in MS group and 16.7% in ES group. 31 patients harbored perisylvian ACs, 89% remained event-free after ES, 71% after MS and 20% after CPS. Clinical improvement immediately after surgery was observed in 58 patients (96.9% in MS, 88.9% in ES and 100% in CPS). A radiological volume reduction could be proven postoperative in 51 patients (78.8% MS, 88.9% ES and 90% CPS). Conclusion: Endoscopic fenestration of AC is a safe and efficient technique which is being widely used nowadays with the highest event free survival compared to microsurgical fenestration especially in perisylvian arachnoid cysts. CPS shows on long terms the highest revision rate but carries the least surgical risks.

Initial Clinical Experience and Biomechanical Analysis of a Novel Gravity Unit-Assisted Valve (M.blue) in Pediatric Patients With Hydrocephalus: A Retrospective Study With Two Years of Follow-up.

BACKGROUND: Overdrainage is a widely reported complication representing common indication for shunt revision. Despite recent advances in valve design, repeated shunt revisions represent burden on healthcare systems. OBJECTIVE: To investigate the efficiency of a novel gravity unit-assisted programmable valve "M.blue" in pediatric hydrocephalus using clinical and biomechanical analyses. METHODS: Thisretrospective single-center study included pediatric patients who received M.blue valve between April 2019 and 2021. Several clinical and biomechanical parameters were documented including complications and revision rates. Flow rate, functional assessment in vertical and horizontal positions, and extent of depositions inside valve were analyzed in explanted valves. RESULTS: Thirty-seven M.blue valves in 34 pediatric patients with hydrocephalus (mean age 2.82 ± 3.91 years) were included. Twelve valves (32.4%) were explanted during a follow-up period of 27.3 ± 7.9 months. One-year survival rate of 89% and overall survival rate of 67.6% with a valve survival average of 23.8 ± 9.7 months were observed. Patients with explanted valves (n = 12) were significantly younger, with 0.91 ± 0.54 years of age in average ( P = .004), and showed significantly more adjustments difficulties ( P = .009 ). 58.3% of explanted valves showed deposits in more than 75% of the valve surface despite normal cerebrospinal fluid findings and were associated with dysfunctional flow rate in vertical, horizontal, or both positions. CONCLUSION: The novel M.blue valve with integrated gravity unit is efficient in pediatric hydrocephalus with comparable survival rate. Deposits inside valves could affect its flow rate in different body positions and might lead to dysfunction or difficulties in valve adjustments.

Emergency Posterior Decompression for Metastatic Spine Tumors in Octogenarians: Clinical Course and Prognostic Factors for Functional Outcomes.

BACKGROUND: This study aimed to describe the clinical outcome of metastatic epidural spinal cord compression in octogenarians with an acute onset of neurological illness who undergo laminectomy, further assess morbidity and mortality rates, and determine potential risk factors for a nonambulatory outcome. METHODS: This retrospective review of electronic medical records at a single institution was conducted between September 2005 and December 2020. Patient demographics, surgical characteristics, complications, hospital course, and 90-day mortality were collected. RESULTS: Thirty-four patients aged 80 years and older who posterior decompression via laminectomy were enrolled in the present study. The mean Charlson Comorbidity Index was >6 (9.2 ± 2.1). The thoracic spine was the most common site of metastasis. A potentially unstable spine, determined using the Spinal Instability Neoplastic Score, was identified in 79.4% of the cases. Preoperatively, the neurological condition and functional status exhibited a notable decline (mean Motor Score of the American Spinal Injury Association grading system, 78.2 ± 16.4; mean Karnofsky Performance Index, 47.8 ± 19.5). The Motor Score of the American Spinal Injury Association grading system and Karnofsky Performance Index scores improved significantly after surgery. Motor weakness and comorbidities were unique risk factors for the loss of ambulation. CONCLUSIONS: Emergent decompressive laminectomy in patients with acute onset of neurological decline and potentially unstable spines improved functional outcome at discharge. Age should not be a determinant of whether to perform surgery; surgery should be performed in older patients when indicated.

ShuntScope-Guided Versus Free-Hand Technique for Ventricular Catheter Placement: A Retrospective Comparative Study of Intraventricular Catheter Tip Position and Complication Rate.

BACKGROUND: The position of the ventricular catheter (VC) is essential for a proper function of cerebrospinal fluid diversion system. A ShuntScope-guided (SG) method might be helpful in reducing complications. The purpose of this study is to compare the accuracy of catheter placement and the complication and revision rates between SG and free-hand (FH) techniques. METHODS: This is a retrospective study based on a prospectively acquired database of patients who underwent VC placement between September 2018 and July 2021. Accuracy of catheter placement was graded on postoperative imaging using the 3-point Hayhurst grading system. Complication and revision rates were documented and compared between both groups with an average follow-up period of 20.84 months. RESULTS: Fifty-seven patients were included. The SG technique was used in 29 patients (mean age was 6.3 years, 1.4-27.7 years, 48.1% females), and the FH technique was used in 28 patients (mean age was 26.7 years, 0.83-79.5 years, 67.9% female). The success rate for the optimal placement of the VC with grade I on the Hayhurst scale was significantly higher in the SG group (93.1%) than in the FH group (60.7%), p = 0.012. The revision rate was higher in the FH group with 35.7% versus 20.7% in the SG group, p = 0.211. CONCLUSION: VC placement using the SG technique is a safe and effective procedure, which enabled a significantly higher success rate and lower revision and complication rate. Accordingly, we recommend using the SG technique especially in patients with difficult anatomy.

Audit of antimicrobial stewardship in medical inpatients in Waikato, New Zealand 2021.

AIMS: Given the threat of rising antimicrobial resistance (AMR), 10 audit standards were selected to audit antimicrobial stewardship (AMS) in secondary care to assess guideline adherence and establish quality improvement initiatives in antimicrobial prescribing. METHODS: Patients were included if they received intravenous (IV) antibiotics across seven medical wards in Waikato or Thames hospitals, New Zealand, in November 2021. Audit standards were defined from the regional antimicrobial prescribing policy and adult antimicrobial guidelines. RESULTS: In total, 205 patients were audited. Microbiological sampling standards were met in 87 of 126 occasions (69.0%). Antimicrobial choices adhered to guidelines in 89 of 163 patients (54.6%), where guidelines were available. Documentation of antimicrobial indications in the medical notes and antimicrobial review at 48 to 72 hours met the standards at over 90%. Only 2 of 13 patients (15.4%) receiving piperacillin/tazobactam or a carbapenem were discussed with Infectious Diseases (ID). Documentation of indications and durations on paper-based medication charts was infrequent, around 12%. Evaluating for health equity, similar results were observed for Maori and non-Maori. CONCLUSIONS: Our audit identified specific areas for AMS quality improvement initiatives. Regular audit should become an essential element of the New Zealand AMS strategy. We believe increased AMS resources are required.

Anterior Access to the Cervicothoracic Junction via Partial Sternotomy: A Clinical Series Reporting on Technical Feasibility, Postoperative Morbidity, and Early Surgical Outcome.

Surgical access to the cervicothoracic junction (CTJ) is challenging. The aim of this study was to assess technical feasibility, early morbidity, and outcome in patients undergoing anterior access to the CTJ via partial sternotomy. Consecutive cases with CTJ pathology treated via anterior access and partial sternotomy at a single academic center from 2017 to 2022 were retrospectively reviewed. Clinical data, perioperative imaging, and outcome were assessed with regards to the aims of the study. A total of eight cases were analyzed: four (50%) bone metastases, one (12.5%) traumatic instable fracture (B3-AO-Fracture), one (12.5%) thoracic disc herniation with spinal cord compression, and two (25%) infectious pathologic fractures from tuberculosis and spondylodiscitis. The median age was 49.9 years (range: 22-74 y), with a 75% male preponderance. The median Spinal Instability Neoplastic Score (SINS) was 14.5 (IQR: 5; range: 9-16), indicating a high degree of instability in treated cases. Four cases (50%) underwent additional posterior instrumentation. All surgical procedures were performed uneventfully, with no intraoperative complications. The median length of hospital stay was 11.5 days (IQR: 9; range: 6-20), including a median of 1 day in an intensive care unit (ICU). Two cases developed postoperative dysphagia related to stretching and temporary dysfunction of the recurrent laryngeal nerve. Both cases completely recovered at 3 months follow-up. No in-hospital mortality was observed. The radiological outcome was unremarkable in all cases, with no case of implant failure. One case died due to the underlying disease during follow-up. The median follow-up was 2.6 months (IQR: 23.8; range: 1-45.7 months). Our series indicates that the anterior approach to the cervicothoracic junction and upper thoracic spine via partial sternotomy can be considered an effective option for treatment of anterior spinal pathologies, exhibiting a reasonable safety profile. Careful case selection is essential to adequately balance clinical benefits and surgical invasiveness for these procedures.
