Lung Perfusion Scintigraphy Reveals a Duplicated Superior Vena Cava With a Right-to-Left Shunt: A Rare Vascular Variant.

Lung perfusion scintigraphy is a common nuclear medicine exam performed for the evaluation of pulmonary emboli, often in the emergency setting. There can be confusion when a radiotracer is located outside of the normal physiologic distribution. This can occur due to improper radionuclide tagging or may be due to anatomic variations. We present a case where a patient presented with bilateral lower extremity deep vein thrombosis and a nuclear medicine lung perfusion scintigraphy showing a complete right-to-left shunt related to a rare anatomical variant of a duplicated superior vena cava (SVC) with the right SVC draining directly into the systemic circulation via the left atrium.

A Case of 177Lu-DOTATATE Therapy Without the Use of Antiemetics.

Recommended 177Lu-DOTATATE treatment regimens involve prophylaxis with antiemetics to counteract the emetogenic properties of the nephroprotective amino acid solution infusion. We describe a 58-y-old woman treated with 177Lu-DOTATATE for metastatic small-bowel carcinoid, who was allergic to many classes of antiemetics. Therefore, she was treated with 177Lu-DOTATATE without antiemetic prophylaxis. She tolerated the compounded amino acid infusion of lysine and arginine, followed by 177Lu-DOTATATE, without significant nausea or any vomiting. We hypothesize that aggressive antiemetic prophylaxis may not be necessary if a 177Lu-DOTATATE patient receives compounded lysine/arginine amino acid solutions. The omission would decrease overall health-care costs and limit possible medication side effects.

A Primary Parotid Mucosa-Associated Lymphoid Tissue Non-Hodgkin Lymphoma in a Patient With Sjogren Syndrome.

The salivary gland tumors are rare entities and the majority of these are benign. However, there are some entities such as prior neck radiation, certain infections, and systemic diseases which should raise the clinical suspicion for a malignant lesion. Patients with Sjogren syndrome are at increased risk for a salivary gland neoplasm, specifically non-Hodgkin lymphoma. While clinical findings play an important role in the initial workup, imaging plays a critical role in the diagnosis and management. This case describes a patient with Sjogren syndrome who presented with a left face mass where imaging was able to confidently diagnose her with a suspicious parotid neoplasm with lymphoma as the favored diagnosis. After histological evaluation, she was diagnosed with primary parotid mucosa-associated lymphoid tissue (MALT) non-Hodgkin lymphoma after which she went on to non-operative management.

Satisfaction with Healthcare Received at an Interprofessional Student-run Free Clinic: Invested in Training the Next Generation of Healthcare Professionals.

Most medical schools in the United States have an associated student-run free clinic (SRFC) providing medical care to the underserved population around the campus. SRFCs provide students with opportunities to practice history-taking and diagnosis skills. There have been a few studies that have evaluated patient satisfaction within SRFCs; however, these studies report limited aspects of care within these clinics. This study hopes to determine the levels of satisfaction with clinical staff and operations and to ensure that the medical needs of patients are being met. Results showed that 91% of the patients were satisfied or very satisfied with their overall clinic experience. The highest scoring parameters were "courtesy/respect of staff", "availability of free or affordable medications", and "doctor's knowledge". Overall, the patients are satisfied with the staff, care, and availability of medicine provided by the Keeping Neighbors in Good Health Through Service (KNIGHTS) clinic. Most patients enjoy participating in the training and education of future physicians and would recommend this clinic to a friend or family member. The lowest satisfaction rates were associated with length of visit and wait time. In the future, SRFCs should work together to assess patient satisfaction in the clinics, identify problem areas, and develop generalizable interventions for improvement.

Raoultella Planticola: Bacteremia and Sepsis in a Patient with Cirrhosis.

This case report describes a 66-year-old male who presented to the emergency department with sepsis and jaundice. He reported that he had been eating seafood at local restaurants for the past two weeks. The medications that he was taking at the time of admission included esomeprazole (proton pump inhibitor (PPI)), which may have contributed to his infection with Raoultella planticola. In addition, the patient had a prior medical history of alcoholic liver cirrhosis, which may have contributed to the bacteremia based on his immunocompromised status.

Colorectal Cancer Presenting with Constipation During Pregnancy.

Colorectal cancer is a rare occurrence during pregnancy and can present with symptoms that are common during pregnancy such as constipation.This can make the diagnosis of colorectal cancer during pregnancy difficult. Management of colorectal cancer during pregnancy is similar to the treatment of non-pregnant patients, but with fetal safety in mind. This case report describes a 33-year-old female gravida two para one (G2P1) at 29 weeks gestation who presented with a complete bowel obstruction. Colonoscopy, magnetic resonance imaging (MRI) and later resection showed an obstructing malignancy which was then resected through an exploratory laparotomy with left hemicolectomy. Postoperatively, there was a concern for sepsis, so labor was induced and the baby was delivered vaginally. The patient then continued with chemotherapy with hematology-oncology. High clinical suspicion is needed to diagnose colorectal cancer during pregnancy. Once diagnosed, surgery can be considered if resectable, taking into account gestational age. Fetal safety is a major consideration during treatment.

A Review of Colorectal Cancer Detection Modalities, Stool DNA, and Fecal Immunochemistry Testing in Adults Over the Age of 50.

Colorectal cancer (CRC) is the third leading cause of cancer death in the United States. Recently, more focus has been placed on developing effective screening tools to detect the presence of both precancerous and cancerous lesions present in the colon and rectum. Colonoscopy has been well established as the gold standard of the colon and rectal cancer screening. However, not all patients are willing to undergo a colonoscopy due to the procedure's invasive nature. Non-invasive screening methods have been developed to appeal to patients who refuse colonoscopy. Fecal occult blood tests have long been used by physicians, in addition to colonoscopy, in an effort to screen for CRC. New screening methods, such as fecal immunochemical test (FIT) and stool DNA (sDNA) testing, have been developed as a more sensitive screening measure to attempt to accurately screen patients who have precancerous or cancerous colorectal lesions. This article compares CRC screening techniques through literature review in order to determine which tests offer the most sensitive detection of CRC and precancerous lesions in average-risk adults over the age of 50 years old. Through this review, it can be seen that sDNA is more sensitive than FIT in detecting all stages of CRC, as well as precancerous lesions.
