Background Flourine-18 fluorodeoxyglucose positron emission tomography-computed tomography (18 F-FDG PET-CT) is a well-established imaging modality for the evaluation of patients with oncological and nononcological conditions. The underlying principle of imaging is the preferentially increased glucose consumption by cancer cells, due to overexpression of glucose type 1 receptors that are insulin independent. Thus, one of the factors that leads to decreased sensitivity of an 18 F-FDG PET-CT is elevated blood sugar levels, leading to decreased glucose uptake by cancer cells due to competitive inhibition. A significant percentage of patients scheduled for PET-CT scan has diabetes mellitus type II as a comorbid condition and often has elevated random blood sugar (RBS) precluding an upfront PET-CT evaluation. Such cases must be rescheduled. This causes delay in the evaluation and management of such patients. Empagliflozin is a novel sodium glucose type 2 inhibitor that prevents tubular reabsorption of glucose and increases renal glycosuria resulting in decreased blood sugar. This drug does not cause significant hypoglycemia or increase endogenous insulin secretion. This study was undertaken to evaluate a potential role for empagliflozin in facilitating optimal blood sugar control in patients with hyperglycemia on the day of the scheduled PET scan. Methods This is an interventional prospective study and patients detected to have RBS more than 200 mg/dL on the day of the scheduled scan were included in the study. The patients were administered two tablets of 10 mg empagliflozin and kept under observation. Samples for RBS were taken at approximately 2nd and 4th hour post administration by bedside method. These patients underwent scan on the same day after adequate sugar control and when an RBS of less than 200 mg/dL was achieved. The primary outcome studied was change in RBS values in the patient cohort and evaluation of PET SUV (standardized uptake value) compared with the rest of the patients scheduled on the same day. Secondary outcome was assessment of any side effects in the patients. Results Total of 10 patients were found to have elevated blood sugar (RBS > 200 mg/dL; irrespective of being on medication) and did not meet the evaluation criteria for a PET-CT scan on the scheduled day. Following administration of the drug, all 10 patients were able to attain blood sugar levels and fulfill the criteria for undergoing a PET-CT scan. No obvious side effect was noted in any of the patient. The SUV values of the patient cohort were comparable with the rest of the patient scanned on the day. Conclusion In this pilot study, 20 mg of empagliflozin (2 tablets of 10 mg) appears to be a safe and effective method for achieving optimal decrease in the RBS without causing hypoglycemia or hyperinsulinemia. It can be safely employed in the subset of population with RBS between 201 and 300 mg/dL to adequately bring the sugar levels at acceptable levels RBS less than 200 mg/dl and fulfill the FDG PET-CT criteria as per European Association of Nuclear Medicine (EANM) norms.

Urethral melanomas are a rare subtype of noncutaneous melanomas. The disease has a tendency to have skip lesions and early metastases as compared with cutaneous melanomas. The role of fluorine-18 fluorodeoxyglucose (18 F-FDG) positron emission tomography computed tomography (PET-CT) is well established in cases of cutaneous melanomas and is recommended by the National Comprehensive Cancer Network (NCCN) for stage IIB to IV cancer. There are no established guidelines on the management of noncutaneous melanomas; however, a recently published United Kingdom national guideline aims to streamline the management of ano-uro-genital melanomas. The guideline describes a very limited role in the use of 18 F-FDG PET-CT in this case scenario. The tendency to skip lesions, early metastases, involvement of brain parenchyma, and finally the usage of anti-PD-1 medications are key areas where 18 F-FDG PET-CT has shown superiority over CT scan. With this case report, we aim to highlight the strength of 18 F-FDG PET-CT in the management of urethral melanomas, which can be extrapolated to other ano-uro-genital melanomas.

Metastasis to the skin remains a rare site of disease involvement in visceral malignancies. It is also a poor prognostic marker for survival. We present a case series of four cases that presented with cutaneous metastasis in a background of solid tumors of the esophagus, gall bladder, kidneys, and lungs, respectively. In all cases, the appearance of the skin lesion acted as a herald that led to the discovery of recurrence or widespread dissemination of the malignancy. Three of the patients passed away within 6 months of the appearance of skin metastases. The use of targeted therapy showed a good response in the patient with renal cell carcinoma with significant regression of disease. [ABSTRACT FROM AUTHOR]

Epithelioid sarcoma (ES) is a rare, clinically polymorphic tumor that afflicts the dermal and subcutaneous region of distal extremity of young adults. In the distal extremity, the involvement of pubic and inguinal region is very rare. We present a case of an epithelioid sarcoma of the pubic region, which was managed, with a combination of upfront surgery and adjuvant therapy, and is presently disease free 5 years after completion of treatment.

Infarction is an uncommon event in a fibroadenoma, which is the commonest benign tumor of the breast. Most often it occurs in pregnancy, lactation or is secondary to fine needle aspiration. Spontaneous infarction of a fibroadenoma in the absence of a predisposing condition is very rare. The cytopathologic features of infarction are necrosis and worrisome nuclear features, which are often misinterpreted as either inflammation or malignancy. We detail a report of accurate cytopathologic diagnosis of spontaneous infarction of fibroadenoma in a 17-year-old adolescent non pregnant girl. Careful attention to the cytopathologic clues like uniform thickness of the necrotic epithelial fragments, branching pattern reminiscent of the staghorn pattern despite atypical nuclear features and clinical details like young age of the patient and recent onset pain in a pre-existing lump helped arrive at the correct diagnosis and spared the patient of a radical excision. To the best of our knowledge, there are no earlier reports of correct cytopathologic diagnosis. [ABSTRACT FROM AUTHOR]

Objective: To examine trends and factors associated with physical therapy (PT) and chiropractic care use among Rhode Islanders with private or publicly-funded health insurance who were diagnosed with chronic pain from 2016-2018., Methods: We measured monthly PT and chiropractic care use from the RI All Payer Claims Database, and conducted logistic regression to identify factors associated with utilization., Results: There were 284,942 unique adults with chronic pain representing over one-quarter of insured persons in the state. Chiropractic care use remained unchanged but was more prevalent (7.2%) than PT whose use increased minimally from 4.0% (2016) to 4.5% (2018). Traditional Medicare or Medicaid enrollment was associated with lower odds of receiving PT and chiropractic care than in private plans., Conclusions: PT and chiropractic care use varied across payers; however, there were little to no changes in their use over time despite clinical guidelines that encourage non-pharmacologic options to manage chronic pain.
