Tailored approach to gastroparesis significantly improves symptoms.

BACKGROUND: Gastroparesis is difficult to treat and many patients do not report relief of symptoms with medical therapy alone. Several operative approaches have been described. This study shows the results of our selective surgical approach for patients with gastroparesis. MATERIALS AND METHODS: This is a retrospective study of prospective data from our electronic medical record and data symptom sheet. All patients had a pre-operative gastric emptying study showing gastroparesis, an esophagogastroduodenoscopy, and either a CT or an upper GI series with small bowel follow-through. All patients had pre- and post-operative symptom sheets where seven symptoms were scored for severity and frequency on a scale of 0-4. The scores were analyzed by a professional statistician using paired sample t test. RESULTS: 58 patients met inclusion criteria. 33 had gastric stimulator (GES), 7 pyloroplasty (PP), 16 with both gastric stimulator and pyloroplasty (GSP), and 2 sleeve gastrectomy. For patients in the GSP group, the second procedure was performed if there was inadequate improvement with the first procedure. There was no mortality. The follow-up period was 6-316 weeks (mean 66.107, SD 69.42). GES significantly improved frequency and severity for all symptoms except frequency of bloating and postprandial fullness. PP significantly improved nausea and vomiting severity, frequency of nausea, and early satiety. Symptom improvement for GSP was measured from after the first to after the second procedure. GSP significantly improved all but vomiting severity and frequency of early satiety, postprandial fullness, and epigastric pain. CONCLUSION: All procedures significantly improved symptoms, although numbers are small in the PP group. GES demonstrates more improvement than PP, and if PP or GES does not adequately improve symptoms GSP is appropriate. In our practice, gastrectomy was reserved as a last resort.

Are triage questions sufficient to assign fall risk precautions in the ED?

OBJECTIVES: The American College of Emergency Physicians Geriatric Emergency Department (ED) Guidelines and the Center for Disease Control recommend that older adults be assessed for risk of falls. The standard ED assessment is a verbal query of fall risk factors, which may be inadequate. We hypothesized that the addition of a functional balance test endorsed by the Center for Disease Control Stop Elderly Accidents, Deaths, and Injuries Falls Prevention Guidelines, the 4-Stage Balance Test (4SBT), would improve the detection of patients at risk for falls. METHODS: Prospective pilot study of a convenience sample of ambulatory adults 65 years and older in the ED. All participants received the standard nursing triage fall risk assessment. After patients were stabilized in their ED room, the 4SBT was administered. RESULTS: The 58 participants had an average age of 74.1 years (range, 65-94), 40.0% were women, and 98% were community dwelling. Five (8.6%) presented to the ED for a fall-related chief complaint. The nursing triage screen identified 39.7% (n=23) as at risk for falls, whereas the 4SBT identified 43% (n=25). Combining triage questions with the 4SBT identified 60.3% (n=35) as at high risk for falls, as compared with 39.7% (n=23) with triage questions alone (P<.01). Ten (17%) of the patients at high risk by 4SBT and missed by triage questions were inpatients unaware that they were at risk for falls (new diagnoses). CONCLUSIONS: Incorporating a quick functional test of balance into the ED assessment for fall risk is feasible and significantly increases the detection of older adults at risk for falls.

Four-Dimensional Computed Tomography for Parathyroid Adenoma Localization: A Pre-Operative Imaging Protocol.

OBJECTIVE: Primary hyperparathyroidism (PHPT) affects approximately 0.86% of the population, with surgical resection as the treatment of choice. A 4D computed tomography (CT) is a highly effective tool in localizing parathyroid adenomas; however, there is currently no defined role for 4D CT when stratified against ultrasonography (USG) and nuclear medicine Technetium Sestamibi SPECT/CT (SES) imaging. STUDY DESIGN: Retrospective Study. SETTING: University Hospital. METHODS: All patients who underwent parathyroidectomy for PHPT between 2014 and 2019 at a single institution were reviewed. Patients who had a 4D CT were included. We compared outcomes of 4D CT as a second line imaging modality to those of USG and SES as first line modalities. An imaging algorithm was proposed based on these findings. RESULTS: There were 84 patients identified who had a 4D CT after unsuccessful first line imaging. A 4D CT localized parathyroid adenoma to the correct quadrant in 64% of cases, and to the correct laterality in 75% of cases. Obese patients had significantly lower rates of adenoma localization with USG (33.4%), compared to non-obese patients (67.5%; P = .006). In determining multigland disease the sensitivity of 4D CT was 86%, while the specificity was 87%. CONCLUSIONS: A 4D CT has impressive rates of accurate localization of parathyroid adenomas; however due to the radiation exposure involved, it should remain a second line imaging modality. PHPT patients should first be evaluated with USG, with 4D CT used if this is unsuccessful and patients are greater than 40 years old, have a high BMI, or are having revision surgery.

Contemporary Management of Primary Hyperparathyroidism.

Primary hyperparathyroidism can be asymptomatic or symptomatic, as well as classic, normocalcemic, or normohormonal. It is important to rule out other causes of hypercalcemia or hyperparathyroidism. Preoperative localization with imaging is necessary for a minimally invasive approach and can be helpful even if planning 4-gland exploration. There are a variety of intraoperative techniques that can assist with localization as well as confirming success. Standard of care remains surgical resection of affected glands. However, there are less invasive management strategies that can be considered for poor surgical candidates.

Factors That Predict Biological Aggressiveness in Estrogen Receptor-Positive / Human Epidermal Growth Factor Receptor 2-Negative / Lymph Node-Negative Breast Cancer.

Background: Traditionally, breast cancer is staged using TNM criteria: tumor size (T), nodal status (N), and metastasis (M). The Oncotype DX assay provides a recurrence score (RS) based on genomics that predicts the likelihood of distant recurrence in estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-)/lymph node-negative (LN-) tumors. Methods: We retrospectively reviewed the medical records of patients with ER+/HER2-/LN- breast cancer tumors who were evaluated between 2007 and 2017 with Oncotype DX RS. We compared the RS to tumor size, patient age, progesterone receptor (PR) status, and LN immunohistochemistry to assess for factors that may independently predict recurrence risk. We also compared tumor size to tumor grade. Results: The data set included 296 tumors: 248 ER+/PR-positive (PR+)/HER2- and 48 ER+/PR-negative (PR-)/HER2-. RS ranged from 0 to 66, patient age ranged from 33 to 77 years, and tumor size ranged from 1 to 65 mm. No significant correlation was found between age and RS (r=-0.073, P=0.208). PR- tumors had a significantly higher RS regardless of size (PR- mean RS 30.8 ± 12.7; PR+ mean RS 16.3 ± 7.3; t(53)=7.6, P<0.0001). No significant correlation was seen between tumor size and RS for all tumors (r=-0.028, P=0.635), and this finding remained true for the PR+ tumor subgroup (r=0.114, P=0.072). However, a significant negative correlation was seen between tumor size and RS in the PR- subgroup (r=-0.343, P=0.017). Further analysis to ensure that differences in tumor grade did not account for this correlation showed equal distribution of well differentiated, moderately differentiated, and poorly differentiated tumors with no significant correlation between tumor size and grade. Conclusion: Increasing tumor size may not be associated with increasing biological aggressiveness. Traditionally, smaller tumors are thought to be lower risk and larger tumors higher risk, with a tendency to use chemotherapy with large tumors. However, our data showed a negative correlation between tumor size and RS in the PR- subgroup. A tumor with PR negativity that reaches a large size without metastasizing may suggest a favorable tumor biology. These tumors may not receive as much benefit from chemotherapy as previously thought. Also, the higher RS seen in smaller PR- tumors may demonstrate PR- status as a predictor for higher risk of distant recurrence. We propose that all tumors meeting the ER+/PR-/LN- criteria, regardless of size, should be considered for genotyping, with the RS used to guide chemotherapy benefit.
