Systematic Review of Syndrome of the Trephined and Reconstructive Implications.

Syndrome of the trephined (SoT) is a severe complication following decompressive craniectomy resulting in neurological decline which can progress to aphasia, catatonia, and even death. While cranioplasty can reverse neurological symptoms of SoT, awareness of SoT is poor outside of the neurosurgery community. The authors performed a systematic review of the literature on SoT with a focus on reconstructive implications. Search terms "syndrome of the trephined" and "sunken flap syndrome" were applied to PubMed to identify primary studies through October 2021. Full-text review yielded 11 articles discussing SoT and reconstructive techniques or implications with 56 patients undergoing cranial reconstruction. Average age of the patients was 41.8±9.5 years. Sixty-three percent of the patients were male. The most common indication for craniectomy was traumatic brain injury (43%), followed by tumor resection (23%), intracerebral hemorrhage (11%), and aneurysmal subarachnoid hemorrhage (2%). Patients most commonly suffered from motor deficits (52%), decreased wakefulness (30%), depression or anxiety (21%), speech deficits (16%), headache (16%), and cognitive difficulties (2%). Time until presentation of symptoms following decompression was 4.4±8.9 months. Patients typically underwent cranioplasty with polyetheretherketone (48%), titanium mesh (21%), split thickness calvarial bone (16%), full thickness calvarial bone (14%), or split thickness rib graft (4%). Eight percent of patients required free tissue transfer for soft tissue coverage. Traumatic Brain Injury (TBI) was a risk factor for development of SoT when adjusting for age and sex (odds ratio: 8.2, 95% confidence interval: 1.2-8.9). No difference significant difference was observed between length until initial improvement of neurological symptoms following autologous versus allograft reconstruction (P=0.47). SoT can be a neurologically devastating complication of decompressive craniectomy which can resolve following urgent cranioplasty. Familiarity with this syndrome and its reconstructive implications is critical for the plastic surgery provider, who may be called upon to assist with these urgent cases.

Decreased readmission rates following use of modified trauma-specific frailty index in older trauma patients: A follow-up study.

INTRODUCTION: Post-discharge readmission rates using modified Trauma-Specific Frailty Index (mTSFI) compared to the Emergency Severity Index (ESI) are unknown. In our pilot study, we demonstrated that mTSFI usage more accurately triages older trauma patients. In the current study, we hypothesized that adult trauma patients triaged using mTSFI would have lower readmission rates at the 30-day interval post discharge. METHODS: Retrospective review of readmission rates for 96 trauma patients ≥ 50 years old was performed. The two study groups were categorized as mTSFI-concordant and ESI-concordant. Fisher's exact test was performed. RESULTS: Mean ages for ESI and mTSFI groups were 63.8 (SD 10.6) and 65.2 (SD 10.8) years. The 30-day readmission rate was 0% (0/32) in the mTSFI group vs 11% (7/64) in the ESI group (p = 0.104). CONCLUSIONS: Utilization of mTSFI for adult trauma patients may lead to lower 30-day readmission rates compared to using ESI, despite our sample sizes being too small to demonstrate a statistically significant difference.

A Comparative Analysis of Hospital Triage Systems in the Geriatric Adult Trauma Patients: A Quality Improvement Pilot Study.

BACKGROUND: The objective of our study is to compare the predicted hospital admission disposition based on the level of risk as determined by the modified Trauma-Specific Frailty Index (mTSFI) score with those determined by arbitrary decisions made based on the Emergency Severity Index (ESI) severity level. METHODS: We surveyed 100 trauma patients ages 50 and older, admitted to a level 1 trauma center between April 2019 and July 2019. We retrospectively reviewed the hospital admission disposition of each patient under the ESI, which was then compared to the mTSFI-predicted hospital admission disposition. The mTSFI scores were calculated by surveying each patient. Statistical analysis was performed to identify any statistical significance of concordance and discordance when comparing the mTSFI and ESI. RESULTS: The average age was 57.6 ± 4.2 years old in the non-geriatric group vs 76.3 ± 7.3 years old in the geriatric group. There was a male predominance in both groups (61% vs 69.5%). The mTSFI identified a higher percentage of triage discordance in the non-geriatric group (73%) compared to the geriatric cohort (53%) (95% difference CI, [39.6-40], P = .05). DISCUSSION: Non-geriatric patients have higher recorded rate of frailty than previously recognized and screening should begin at age 50, not 65. The mTSFI may be an effective tool to appropriately triage adult trauma patients at increased risk due to frailty and may reduce in-hospital complications.

Traumatic Brain Injury as a Potential Risk Factor for Diabetes Mellitus in the Veteran Population.

This review examines various aspects of traumatic brain injury (TBI) and its potential role as a causative agent for type 2 diabetes mellitus (T2DM) in the veteran population. The pituitary glands and the hypothalamus, both housed in the intracranial space, are the most important structures for the homeostatic regulation of almost every hormone in the human body. As such, TBI not only causes psychological and cognitive impairments but can also disrupt the endocrine system. It is well established that in addition to having a high prevalence of chronic traumatic encephalopathy (CTE), veterans have a very high risk of developing various chronic medical conditions. Unfortunately, there are no measures or prophylactic agents that can have a meaningful impact on this medically complex patient population. In this review, we explore several important factors pertaining to both acute and chronic TBI that can provide additional insight into why veterans tend to develop T2DM later in life. We focus on the unique combination of risk factors in this population not typically found in civilians or other individuals with a non-military background. These include post-traumatic stress disorder, CTE, and environmental factors relating to occupation and lifestyle.

Open Retroperitoneal Inferior Vena Cava Cannulation for Distal Ventriculoatrial Shunt Catheter Placement.

Multiple alternative sites for distal ventriculoperitoneal shunts have been described including pleural, atrial, ureteral, fallopian, and gallbladder placement. In medically complex patients the sites for cerebrospinal fluid (CSF) diversion can be exhausted. We present a case where open retroperitoneal inferior vena cava cannulation was used for successful atrial catheter placement in a 17-month-old female. The patient had a complex abdominal, pulmonary, and vascular history precluding placement of the distal catheter in other sites or atrial placement through more peripheral venous cannulation. The patient underwent uncomplicated open retroperitoneal exposure of her inferior vena cava (IVC) with cannulation and placement of atrial catheter under fluoroscopic guidance. At the follow-up one year after surgery, the patient did not require revision with appropriate placement of the distal atrial catheter.

Disparities Regarding Inadequate Automated External Defibrillator Training and Potential Barriers to Successful Cardiac Resuscitation in Public School Systems.

Installation of automated external defibrillators (AEDs) in public schools has been shown to improve outcomes for children with sudden cardiac arrest (SCA). However, the adequacy of faculty AED training and potential barriers to successful cardiac resuscitation remain unknown. A questionnaire was mailed to all public schools in the state of Illinois (n = 3796). The survey focused on the demographic variables of each school as well as the confidence of the responder regarding effectiveness of AED training. 2,192 surveys were included in this study (58% response rate). Independent variables for perceived inadequate AED training were schools that were predominantly black (odds ratio [OR] 3.93; 3.01 to 5.13) or Hispanic (OR 2.75; 2.11 to 3.58), elementary schools (OR 2.05; 1.69 to 2.50), schools with <250 students (OR 1.69; 1.19 to 2.40) and <25 faculty (OR 1.54; 1.10 to 2.15). Eighty-eight percent of responders cited at least one barrier to successful AED utilization. Location in a town setting (OR 9.34; 4.73 to 18.44) or rural setting (OR 3.18; 2.47 to 4.10) as well as upper socioeconomic status (OR 3.85; 2.04 to 7.29) were found to be predictors of schools with no barriers to AED utilization.

Prevalence and predictors of inappropriate anticoagulation in patients with a CHA2DS2-VASc score of 0 and atrial fibrillation.

BACKGROUND: Previous studies have shown underutilization of anticoagulation therapy in patients with atrial fibrillation and a CHA2DS2-VASc score ≥2; however there exists little data regarding the inappropriate use of anticoagulation in patients with a CHA2DS2-VASc score of 0. We aimed to determine the true prevalence and predictors of inappropriate anticoagulation therapy in patients with atrial fibrillation and a CHA2DS2-VASc score of 0. METHODS: A retrospective chart review was performed on all patients with atrial fibrillation and a CHA2DS2-VASc score of 0 in our institution from January 2009 to January 2016. Demographic and clinical data were collected from the electronic medical record. We utilized multivariable logistic regression analysis to determine independent clinical predictors of inappropriate anticoagulation administration. RESULTS: 512 patients were identified with a CHA2DS2-VASc score of 0 and a diagnosis of atrial fibrillation. Of the 137 patients prescribed anticoagulation, 64 patients were identified as inappropriately treated with anticoagulation therapy after assessing for other indications of warfarin or novel anticoagulant therapy. Independent variables associated with inappropriate anticoagulation administration were age (OR 1.07; 95% CI 1.03-1.10), body mass index (OR 1.06; 95% CI 1.01-1.10), absence of current aspirin use (OR 13.50; 95% CI 6.00-30.54) and persistent atrial fibrillation (OR 2.34; 95% CI 1.11-4.94). CONCLUSIONS: Our study shows that 12% of patients with a CHA2DS2-VASc score of 0 were inappropriately prescribed anticoagulant therapy. Independent predictors of unnecessary anticoagulation were age, body mass index, absence of current aspirin use and persistent atrial fibrillation.
