    Progressive supranuclear palsy: A case report and brief review of the literature

    No full text
    Atypical Parkinsonian syndromes are a subset of progressive neurodegenerative disorders that present with signs of Parkinson\u27s disease. However, due to multisystem degeneration, the atypical Parkinsonian syndromes have additional symptoms that are often referred to as Parkinson-plus syndromes. The most well-studied subsets include progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal degeneration (CBD), and Lewy body dementia. Specifically, progressive supranuclear palsy is a tauopathy neurodegenerative disorder that presents with parkinsonism symptoms along with postural instability, vertical saccade, and vertical gaze palsy. Here, we present a case of PSP and provide a brief review of the literature

    Are 99mTC-Sestamibi Single Photon Emission Computed Tomography Scan Results Associated to the Parathyroid Cell Type in Primary Hyperparathyroidism?

    No full text
    INTRODUCTION: TC-sestamibi scintigraphy (SPECT-CT) is a common imaging modality for parathyroid localization in primary hyperparathyroidism (PHPT). Prior studies have suggested that the cellular composition of parathyroid adenomas influences SPECT-CT imaging results. Other biochemical and anatomical factors may also play a role in false negative results. Therefore, after controlling for confounding variables, we sought to determine whether the histologic composition of parathyroid adenomas is associated to SPECT-CT results in patients with single gland disease causing PHPT. METHODS: A retrospective review of patients with PHPT due to confirmed single gland disease was performed over a 2-y period. A 1:1 propensity score matching was done between patients with positive and negative SPECT-CT results with regard to demographical, biochemical, and anatomical characteristics followed by blinded pathologic examination of cell composition in the matched pairs. RESULTS: Five hundred forty two patients underwent routine four gland exploration and 287 (53%) patients were found to have a single adenoma. Of those, 26% had a negative SPECT-CT result. There were significant differences between groups with regards to biochemical profile, gland location, and gland size. All of which became nonsignificant after propensity score matching. Adenomas were primarily composed of chief cells, with no difference between groups (95% versus 97%, P = 0.30). In the positive SPECT-CT group, chief cells were the dominant cell type in 68% of the cases, followed by mixed type (13%), oxyphil cells (12%), and clear cells (7%). This was similar to the negative SPECT-CT group (P = 0.22). CONCLUSIONS: While certain patient\u27s clinical characteristics are associated with SPECT-CT imaging results, histologic cell type is not significantly associated

    Agreement and disagreement between child-caregiver symptom and function reports in pediatric oncology

    BACKGROUND/OBJECTIVE: The use of patient-reported outcomes (PRO) is increasing in pediatric clinical practice and research, including in clinical trials. Treatment teams are now able to discern differences in symptom and function reports between children with cancer and their family caregivers. Few studies, however, have quantified such differences. DESIGN/METHODS: Children and caregivers were matched to create a dyad sample, and child/caregiver agreement of responses to the Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric symptom and function measures were examined using the established minimally important difference (MID) value (three points) derived from these measures. Latent class analysis (LCA) was then used to analyze the status/patterns of response agreement. RESULTS: A total of 430 dyadic cases (dyads) were used for LCA modeling. Three classes of child-caregiver concordance resulted: (a) Agreement-caregiver and child within one MID (200 dyads); (b) Disagreement-caregiver underestimating symptoms (47 dyads with caregiver scores more than 1 MID lower than the child scores); and (c) Disagreement-caregiver overestimating symptoms (183 dyads with caregiver scores more than 1 MID higher than child scores). CONCLUSION: As PRO use increases in pediatric oncology, clinician identification of child/caregiver differences on symptom and function reports will help to distinguish family perceptions of cancer treatment impact. The treatment goal, in addition to mitigating symptom and function treatment-related burdens for the child and caregiver, may now also be to discern the direction and clinical meaning of the difference within the child-parent dyad

    0.05% Chlorhexidine Gluconate Irrigation in Trauma/Emergency General Surgical Laparotomy Wounds Closure: A Pilot Study

    No full text
    INTRODUCTION: Patients who undergo exploratory laparotomy (EL) in an emergent setting are at higher risk for surgical site infections (SSIs) compared to the elective setting. Packaged Food and Drug Administration-approved 0.05% chlorhexidine gluconate (CHG) irrigation solution reduces SSI rates in nonemergency settings. We hypothesize that the use of 0.05% CHG irrigation solution prior to closure of emergent EL incisions will be associated with lower rates of superficial SSI and allows for increased rates of primary skin closure. METHODS: A retrospective observational study of all emergent EL whose subcutaneous tissue were irrigated with 0.05% CHG solution to achieve primary wound closure from March 2021 to June 2022 were performed. Patients with active soft-tissue infection of the abdominal wall were excluded. Our primary outcome is rate of primary skin closure following laparotomy. Descriptive statistics, including t-test and chi-square test, were used to compare groups as appropriate. A P value \u3c0.05 was statistically significant. RESULTS: Sixty-six patients with a median age of 51 y (18-92 y) underwent emergent EL. Primary wound closure is achieved in 98.5% of patients (65/66). Bedside removal of some staples and conversion to wet-to-dry packing changes was required in 27.3% of patients (18/66). We found that most of these were due to fat necrosis. We report no cases of fascial dehiscence. CONCLUSIONS: In patients undergoing EL, intraoperative irrigation of the subcutaneous tissue with 0.05% CHG solution is a viable option for primary skin closure. Further studies are needed to prospectively evaluate our findings

    Gaseous Nitric Oxide-Cangrelor Combination to Prevent Clots in Extracorporeal Life Support System

    No full text
    INTRODUCTION: The objective of this study was to investigate the potential synergistic utility of a combination of gaseous nitric oxide (gNO)-intravenous Cangrelor as an effective pharmacological option for the prevention of thrombosis in an animal model of extracorporeal life support (ECLS) circuits. METHODS: 10 newborn lambs were placed on ECLS. 5 of them were administered a combination of gNO and intravenous Cangrelor. The remaining 5 were not administered any anticoagulant. The primary end point was duration of ECLS without clot formation. The secondary outcome measure was the absolute maximum transmembrane pressure gradient. RESULTS: The mean duration of ECLS were 168 min (standard deviation 224.98 min) in the control group and 402 min (standard deviation 287.5 min) in the experimental group (P = 0.17). The peak trans-oxygenator pressure difference was 43 mm Hg (standard deviation 23 mm Hg) in the control group and 62 mm Hg (standard deviation 71 mm Hg) in the experimental group(P = 0.64). Two animals in the experimental group were supported up to 12 h without clot formation. Clot formation in the experimental group occurred after placement of the cannulae but prior to initiation of ECLS flows after cannulation. CONCLUSIONS: A combination of gNO and Cangrelor is prevents clot formation in an experimental animal model when administered through a clean clot-free circuit. However, the combination s ineffective when there are pre-existing clots in the circuit. A bolus of anticoagulation prior to cannulation is needed prior to testing this combination in future studies with a larger sample size

    Do Females Have Worse Outcomes in Penetrating Trauma: A Single-Center Analysis

    No full text
    INTRODUCTION: Penetrating trauma occurs less frequently in females than in males. Studies on penetrating injuries are conducted in predominantly male populations. We aim to elucidate the demographics and outcomes of penetrating trauma specifically in females to mitigate disparities of care in females. MATERIALS AND METHODS: A retrospective review of hospitalized adult trauma patients suffering penetrating trauma from 2015 to 2021 was performed in an urban American College of Surgeon-verified level 1 trauma center. Patients were stratified by sex (females or males) and mechanism of injury (gun-related versus nongun-related). The primary outcome was mortality, and secondary outcomes included incidence of blood transfusion, incidence of surgical/interventional radiology (IR) interventions, hospital length of stay (LOS), and complications. Descriptive statistics were employed with a significance defined as P value \u3c0.05. A multivariate logistic regression was used to determine the impact of sex on mortality, surgical/IR interventions, and hospital LOS. RESULTS: Females with penetrating injury had lower Injury Severity Score (1 versus 4, P \u3c 0.05) than males, but had similar mortality rates (4% versus 6%, P = 0.06). In multivariable logistic analysis adjusting for age and Injury Severity Score, while females experience 33% fewer OR/IR intervention, there was no statistically significant difference in mortality rates, hospital LOS, and complication rates between males and females. CONCLUSIONS: Despite receiving fewer surgical/IR intervention, females with penetrating injuries have similar outcomes to their male counterparts. Further study is needed to study this discrepancy

    OBJECTIVE: This study aimed to determine long-term cardiometabolic effects of hormone therapies initiated within 3 years of onset of menopause after a 14-year follow-up study of participants of the Kronos Early Estrogen Prevention Study (KEEPS). METHODS: KEEPS was a multisite clinical trial that recruited recently menopausal women with good cardiovascular health for randomization to oral conjugated equine estrogens (Premarin, 0.45 mg/d) or transdermal 17β-estradiol (Climara, 50 μg/d) both with micronized progesterone (Prometrium, 200 mg/d) for 12 d/mo, or placebo pills and patch for 4 years. KEEPS continuation recontacted KEEPS participants 14 years after randomization and 10 years after the completion of the 4-year clinical trial to attend in-person clinic visits. RESULTS: Participants of KEEPS continuation (n = 299 of the 727 KEEPS participants; 41%) had an average age of 67 years (range, 58-73 y). Measurements of systolic and diastolic blood pressures, waist-to-hip ratio, fasting levels of glucose, insulin, lipid profiles, and homeostasis model assessment of insulin resistance were not different among the treatment groups at either KEEPS baseline or at KEEPS continuation visits, or for change between these two visits. The frequency of self-reported diabetes ( P = 0.007) and use of diabetes medications was higher in the placebo than the oral conjugated equine estrogens ( P = 0.045) or transdermal 17β-estradiol ( P = 0.02) groups, but these differences were not supported by the laboratory measurements of glycemia or insulin resistance. CONCLUSIONS: There was no evidence of cardiovascular and/or metabolic benefits or adverse effects associated with 4 years use of oral or transdermal forms of hormone therapy by recently menopausal women with good cardiovascular health after 10 years
