The Effect of Transversus Abdominis Plane Block Timing on Milliequivalents of Opioid Use and Immediate Postoperative Pain Scores in Patients Undergoing Minimally Invasive Hysterectomy: A Retrospective Cohort Study.

STUDY OBJECTIVE: To examine the effect of transversus abdominis plane (TAP) block timing (preoperative or postoperative) on postoperative opioid use (quantified via morphine milligram equivalents; MME) and pain scores in patients undergoing minimally invasive hysterectomy for benign indications. DESIGN: Retrospective, single-institution cohort study SETTING: Academic-affiliated community hospital PATIENTS: A total of 2982 patients were included who underwent a minimally invasive total hysterectomy between January 2018 and December 2022, excluding patients with a malignancy diagnosis, concurrent urogynecological procedure, vaginal hysterectomy, supracervical hysterectomy, or those with baseline narcotic use (opioid use within the 3 months before surgery). Patients were separated into 3 groups: no TAP blocks (n = 1966, 65.9%), preoperative TAP blocks (854, 28.6%), and postoperative TAP blocks (162, 5.4%). INTERVENTIONS: Summary statistics and mixed-effects regression methods were used for data analysis. MEASUREMENTS AND MAIN RESULTS: There was a statistically significant lower mean use of opioids (MME 43.2 vs 53.9, p = .002) among patients who received a TAP block (either pre or postoperatively) than those who did not receive a block. However, when comparing preoperative vs postoperative patients with TAP block, there was no statistically significant difference in mean opioid use (MME 43.4 vs 42.1, p = .752). There were no differences in postoperative pain scores between patients with and without a TAP block, however, more opioids were required in patients who did not receive a TAP block to achieve the same pain scores as those who did receive a TAP block. There was a statistically significant shorter time to discharge for TAP versus patients without TAP block(median 5.5 vs 6.3 hours, p ≤ .001) as well as preoperative versus postoperative patients with TAP block (median 5.3 vs 6.2 hours, p = .001). CONCLUSION: While TAP block use at the time of minimally invasive hysterectomy reduced use of postoperative opioids, the timing of TAP block, either preoperatively or postoperatively, did not significantly affect opioid use. Preoperative compared with postoperative TAP block administration significantly shortened the time to discharge.

A Rare Case: Adrenal Corticomedullary Mixed Tumor With Elements of Pheochromocytoma, Cortical Adenoma, and Ganglioneuroma Cells.

Background/Objective: Adrenal corticomedullary mixed tumor (CMMT) are extremely rare single adrenal tumor masses containing a mixture of adrenal cortical adenoma and pheochromocytoma cells. Case Report: A 52-year-old woman presented with clinical and biochemical evidence of cortisol and catecholamine excess and was found to have an adrenal CMMT with intermixed chromaffin, cortical adenoma, and ganglioneuroma components. She underwent a successful unilateral adrenalectomy with subsequent improvement in her symptoms. Discussion: We report the first case of a patient with a CMMT that had symptoms of both catecholamine and cortisol excess from her tumor. Typically, patients with similar tumors have signs of cortisol excess; however, the pheochromocytoma portion is clinically silent. Although most CMMT contain 2 distinct cell types, this is the third ever described case of a single adrenal CMMT containing 3 unique cellular components: (1) intermixed chromaffin, (2) cortical adenoma, and (3) ganglioneuroma cells. Conclusion: Our understanding of these rare tumors is limited, and this case serves to broaden our knowledge about their clinical, biochemical, and pathologic features.

Opioid-induced adrenal insufficiency: diagnostic and management considerations.

The dramatic rise in opioid use over the last two decades has led to a surge in their harmful health effects. Lesser known among clinicians is the impact of opioids on the endocrine system, especially with regard to cortisol. Opioids can suppress the hypothalamus-pituitary-adrenal (HPA) axis and may result in clinically significant adrenal insufficiency, especially in those treated at higher doses and for a longer time. A high clinical suspicion is necessary in this population for early diagnosis of opioid-induced adrenal insufficiency (OAI). Diagnosis of OAI is challenging, as the symptoms are often vague and overlap with those due to opioid use or the underlying pain disorder. Traditional assays to diagnose adrenal insufficiency have not been widely studied in this population, and more investigation is needed to determine how opioids might affect assay results. Once a diagnosis of adrenal insufficiency has been made, glucocorticoid replacement in the form of hydrocortisone is likely the mainstay of treatment, and effort should be made to taper down opioids where possible. Cortisol levels should be retested periodically, with the goal of stopping glucocorticoid replacement once the HPA axis has recovered. In this review, we provide context for diagnostic challenges in OAI, suggest diagnostic tools for this population based on available data, and offer recommendations for the management of this disorder. There is a paucity of literature in this field; given the widespread use of opioids in the general population, more investigation into the effects of opioids on the HPA axis is sorely needed.

Adnexal torsion: a review of diagnosis and management strategies.

PURPOSE OF REVIEW: Adnexal torsion remains a diagnostic challenge heavily reliant on high clinical suspicion, with patient presentation and imaging used as adjuncts to aid in its diagnosis. This review summarizes diagnostic and management techniques of adnexal torsion to assist providers when encountering this surgical emergency. RECENT FINDINGS: Common findings of adnexal torsion include abdominal pain, nausea, vomiting, and adnexal mass or ovarian enlargement. An elevated neutrophil to lymphocyte ratio may be useful for diagnosis. A 'whirlpool' sign, 'follicular ring' sign, enlarged/edematous ovary, and absent Doppler flow to the ovary are highly suggestive of adnexal torsion. Intraoperative visual diagnosis of ovarian death is highly inaccurate, with only 18-20% of ovaries necrotic on pathological examination. Necrotic appearing ovaries have been shown to have follicular activity on ultrasound one year postoperatively. SUMMARY: Pelvic ultrasound remains the first-line imaging modality. In patients of reproductive age, we recommend performing detorsion with ovarian conservation, even in cases where the tissue appears necrotic, given poor intraoperative diagnostic rates of tissue death. Retention of ovarian function is also reliant on a timely diagnosis and intervention. We emphasize that the risk of ovarian damage/loss outweigh the risk of a diagnostic laparoscopy in patients of reproductive age.

Tale of 2 Health-care Systems: Disparities in Demographic and Clinical Characteristics between 2 Ischemic Stroke Populations in Los Angeles County.

BACKGROUND: Individuals who present to the emergency departments of safety-net systems often have poorly controlled risk factors due to lack of primary care. Little is known about potential differences in presenting characteristics, discharge medications, and discharge destinations of patients with acute ischemic stroke (AIS) who present to safety-net settings versus university medical centers (UMCs). METHODS: Demographic characteristics, medical history, premorbid medication use, stroke severity, discharge medications, and discharge destination were assessed among consecutive admissions for AIS over a 2-year period at a UMC (n = 385) versus 2 university-affiliated safety-net hospitals (SNHs) (n = 346) in Los Angeles County. RESULTS: Compared with patients presenting to the UMC, individuals admitted to the SNHs were younger, more frequently male, nonwhite, current smokers, hypertensive, and diabetic; they were less likely to take antithrombotics and statins before admission, and had worse serum lipid and glycemic markers (all P < .05). Patients admitted to the UMC trended toward more cardioembolic strokes and had higher stroke severity scores (P < .0001). At discharge, patients admitted to the SNHs were more likely to receive antihypertensive medications than do patients admitted to the UMC (P < .001), but there were no differences in prescription of antiplatelet medications or statins. CONCLUSIONS: Individuals with AIS admitted to SNHs in Los Angeles County are younger and have poorer vascular risk factor control than their counterparts at a UMC. Discharge treatment does not vary considerably between systems. Early and more vigorous efforts at primary vascular risk reduction among patients seen at SNHs may be warranted to reduce disparities.
