Fat Embolism Does Not Alter Cardiac Structure or Induce Pathological Changes in a Rat Model.

INTRODUCTION: Fat embolism (FE) encompasses conditions in which fatty substance becomes embedded in a tissue/organ. Fat emboli most commonly affect the lungs in a trauma setting. This can lead to both significant pathology locally and systemically including changes in structure, inflammatory response, activation of the renin-angiotensin system, and subsequent hypoxia. In fact, changes in skin, brain, lungs, and kidneys have been noted in FE syndrome. Because there is an extensive record of pathology reports on this condition without evidence of direct cardiac involvement, as well as our studies showing apparent complete recovery after the acute embolism, we hypothesized that structural changes similar to the lung and at the same time course would not be observed in the heart. METHODS: We used a rat model of FE previously described by our group where we have documented significant lung pathology. In this study, we analyzed both pulmonary and cardiac structure, histology, and gene expression at 48 h and 10 wks post fat injection to mimic FE. RESULTS: Despite severe inflammatory evidence and structural changes to the lung and vasculature up to 10 wks after FE, we found no significant alterations to cardiovascular morphometry including lumen patency ratio, adventitia/media ratio, fibrosis content, and heart chamber/wall dimensions in stained histological sections. Additionally, genetic markers of cardiac pathological hypertrophy were not significantly elevated 48 h or 10 wks after fat treatment. Oil Red O staining showed increased fat droplet content within lung and aorta tissue, but not in the myocardium. CONCLUSIONS: Our study suggests that, in contrast to the lungs, the heart is more resistant to the inflammatory and remodeling responses that result from FE, possibly due to the organ-specific differences in fat retention.

Mammary analogue secretory carcinoma of salivary gland diagnosed on submandibular gland cytology: A case report and review of the literature.

Mammary analogue secretory carcinoma of the salivary glands has morphological shares molecular similarities to secretory carcinoma of the breast. Here, we report a 46-year-old woman who presented with a right submandibular gland mass. Fine needle aspiration differential diagnosis included oncocytosis, oncocytoma, acinic cell carcinoma and mammary analogue secretory carcinoma. We also review the current literature regarding clinical presentation and diagnostic workup of this entity.

Metastatic Small Cell Lung Cancer Masquerading as a Pancreatic Mass: A Case Report.

Small cell lung cancer (SCLC) is notorious for its aggressive behavior and propensity for metastasis. Although metastasis to the pancreas from SCLC is relatively rare, it warrants attention due to its overlapping symptomatology with primary pancreatic malignancies and other abdominal pathologies (such as those involving the liver or gallbladder). Despite recent advances, the mechanisms driving SCLC metastasis to the pancreas remain elusive, providing challenges in diagnosis and treatment. This case report details the presentation of a 59-year-old woman with SCLC metastasis to the pancreas, initially masquerading as primary pancreatic carcinoma, as highlighted by her presenting symptoms of jaundice, weight loss, and abdominal pain. Diagnostic workup, including imaging studies and tissue sampling, confirmed the unexpected presence of metastatic SCLC in the pancreas. The patient was ultimately transferred to a tertiary care facility for further workup. This case serves as a reminder to maintain a broad differential diagnosis, particularly in the face of such an unusual presentation. It also highlights the need for further research to elucidate the molecular and cellular mechanisms driving SCLC metastasis to the pancreas, with the ultimate goal of improving diagnostic accuracy and therapeutic outcomes for patients with this aggressive disease.

COVID-19 Presenting as Acute Icteric Hepatitis.

As the coronavirus pandemic continues to evolve, so does the understanding of different presentations of disease. In this case report, we describe a patient whose presentation of COVID-19 was with acute icteric hepatitis without respiratory symptoms. This is the first case in the literature to our knowledge to report jaundice as the initial presentation of disease and adds to just a handful of cases in the literature of acute hepatitis as the sole presentation of COVID-19. Additionally, despite severe hepatitis, the patient had a benign course of COVID-19 and did not require aggressive medical care; this strays from conventional paradigms that associate severity of COVID-19 with a degree of aminotransferase elevation. The purpose of this report is to make physicians aware of acute icteric hepatitis as a presentation of COVID-19 infection and to facilitate discussion and further research in the area of COVID-19-induced hepatitis.

Rare case of male breast intraductal papilloma progressing to invasive ductal carcinoma: A radiologic-pathologic correlation.

Although male breast cancer represents only 0.5%-1% of all breast cancer cases in the United States, the incidence of this disease is slowly rising [1]. Because of its extremely low prevalence, screening and treatment guidelines are not well established. Thus, analyzing cases of male breast cancer can accelerate this process. We present a case of a 52-year-old man, initially diagnosed with biopsy-confirmed intraductal papilloma without atypia, who presented 3 years later with progression of this benign lesion to ductal carcinoma in situ and development of de novo invasive ductal carcinoma. This report stresses the importance of symptom detection and risk factor modification with the goal of decreasing the incidence of this disease.

Russian olive (Elaeagnus angustifolia L.): From a variety of traditional medicinal applications to its novel roles as active antioxidant, anti-inflammatory, anti-mutagenic and analgesic agent.

Elaeagnus angustifolia L., which is commonly known as oleaster or Russian olive, is a deciduous plant from Elaeagnacea family. This plant can tolerate and survive a wide variety of environmental conditions. Different parts of E. angustifolia plant, especially the fruits and flowers, have been used traditionally in treating a variety of common illnesses such as nausea, cough, asthma, fever, jaundice, and diarrhea. The use of fruit powder and extract of E. angustifolia L. have shown to be effective in alleviating pain in patients with rheumatoid arthritis and also in reducing the healing time of wounds in injured person. In addition, some recent reports have indicated the anti-oxidant, anti-inflammatory, antimicrobial, anticancer and some other properties of oleaster plant. The other important property of this plant would be its role in bio-monitoring the environment for some toxic elements and also its action as a bio-fertilizer agent in distressed lands. It seems that with more advanced studies on E. angustifolia L. and its bioactive components, this plant might be potentially effective and can be used as a natural alternative resource in pharmaceutical industries for treating chronic and serious problems, Fig. 1.

Recent studies suggest that the use of some Satureja species is effective in protecting the body against oxidative stress, free radical damage, inflammation, microbial infections, etc., A review of many studies suggests that savory species, in addition to treating minor ordinary ailments, can potentially provide a novel natural prevention or treatment for some chronic and serious illnesses such as diabetes, cardiovascular diseases, cancer, and Alzheimer's.

Frankincense ( rǔ xiang; boswellia species): from the selection of traditional applications to the novel phytotherapy for the prevention and treatment of serious diseases.

Frankincense ( Rǔ Xiang; Boswellia Species), the resinous extract from the trees of the genus Boswellia, has been used for centuries in cultural ceremonies, as a cosmetic agent, and as a traditional medicine to treat a variety of ailments, especially inflammatory diseases including asthma, arthritis, cerebral edema, chronic pain syndrome, chronic bowel diseases, cancer, and some other illnesses. Boswellic acids are the active compounds of frankincense and AKBA (3-O-acetyl-11-keto-ß-boswellic acid) is the most important and effective acid among them. Some studies have shown that the use of frankincense can also improve the learning and enhance the memory in animals and human beings. It seems that frankincense might have a potential ability to be used as an alternative natural medicine not only for chronic and inflammatory diseases but also for brain and memory disorders.
