Nonbacterial thrombotic endocarditis (NBTE) is a rare entity most commonly diagnosed postmortem with rates in autopsy series ranging from 0.9 to 1.6%. A 63-year-old female with past medical history of hypertension and mitral valve prolapse presented to the hospital with shortness of breath, headache, and necrotic skin lesions on her hands and feet. Computed tomography (CT) scan of her chest demonstrated a pulmonary embolus in the right lower lung segmental artery and right upper lobe lobar to segmental pulmonary artery, a mass-like consolidation in the left upper lung field impeding the hilum. CT scan of the abdomen demonstrated metastatic disease in liver and bone and bilateral femoral deep vein thrombosis. Transesophageal echocardiography revealed severe mitral regurgitation with two small mobile plaques on the mitral valve and two immobile plaques on the descending aorta. Magnetic resonance imaging of the brain was consistent with subacute infarcts and metastatic disease. Bronchoscopy was performed and pathology revealed primary adenocarcinoma of the lung. She was treated with anticoagulation and systemic chemotherapy. The patient and family elected to proceed with hospice due to her clinical decline, poor performance status, and poor prognosis after a prolonged hospital stay. Underlying malignancy is detected in approximately 40-85% of patients with NBTE. Lung cancer is the most frequently associated malignancy followed by pancreatic, stomach, breast, and ovarian cancer. Widespread necrotic skin lesions as presenting symptoms of primary lung adenocarcinoma are rare. In the present case, the diagnosis of necrotic skin lesions and NBTE preceded that of the neoplastic disease. Necrotic skin lesions and NBTE can be the first manifestations of an occult malignancy causing extensive multi-organ infarcts. NBTE can present with such extensive skin lesions as a first presenting sign of malignancy. To the best of our knowledge, this is the first case to present with such extensive skin lesions as the first presenting symptom of lung adenocarcinoma.

The evolution of skull base approaches associated with individualization of surgical corridor and minimizing the collateral damage. Achieving the radical removal of tumor and preserving the neurological status of the patient is possible, both with the traditional approaches and keyhole approaches. Our work presents experience using the transpalpebral approach (TPA) for microsurgical removal of tuberculum sellae meningioma (TSM).

The purpose of this study was to examine the state of smartphone applications for cancer intended for the general public with a focus on interactive features, content sources, and application developer affiliations. The level of health provider involvement in screening or appraising application content was also assessed.

Burning mouth syndrome (BMS) is a chronic condition characterized by a burning sensation of the oral cavity and is often associated with taste disturbances and xerostomia. It primarily affects menopausal or postmenopausal women. Idiopathic or primary BMS can occur spontaneously and without any identifiable precipitating factors. When BMS is associated with systemic factors, it is defined as secondary BMS. While the exact etiology of BMS is still unknown, the condition appears to be multifactorial, and numerous local, systemic, and psychological factors have been associated with it. Primary BMS is a diagnosis of exclusion and can only be reached after all potential causes of secondary burning pain have been eliminated. Management strategies include reassurance of the patient as well as pharmacologic agents such as clonazepam, supplements such as α-lipoic acid, and psychological therapy.

Although opioids are a commonly prescribed form of analgesics among the armamentarium for their efficacy and safety when used responsibly, societal problems of drug diversion are highly prevalent. This review seeks to examine the importance of opioids and the extent of diversion and its impact, drawbacks, and controversies in law, public policies, and strategies. In particular, the law has skewed its focus toward the regulation of opioid suppliers (as compared to consumers), giving rise to a chilling effect where physicians are hesitant to prescribe opioids to patients with legitimate needs. This has downplayed the importance of medically treating pain, especially in the context of palliative care. This article recommends the intelligent use of public policy to alleviate the opioid diversion problem while acknowledging the importance of appropriate pain management. Concurrently, this article recommends providing continuous education and support for physicians, dispensers, and the like and adoption of soft law approaches by legislators and enforcement bodies to prevent relentless clamping down on opioid abusers. In conclusion, appropriate policies and guidelines are necessary to support the entire health care body in executing a coordinated approach and exercising vigilance to better manage the opioid diversion problem.

Chronic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel disease, spondyloarthritis and psoriasis cause significant morbidity and are a considerable burden for the patients in terms of pain, impaired function and diminished quality of life, as well as for society, because of the associated high health-care costs, and loss of productivity. Our limited understanding of the pathogenic mechanisms involved in these diseases currently hinders early diagnosis and the development of more specific and effective therapies. The past years have been marked by considerable progress in our insight of the genetic basis of many diseases. In particular, genome-wide association studies (GWAS) performed with thousands of patients have provided detailed information about the genetic variants associated with a large number of chronic inflammatory diseases. These studies have brought to the forefront many genes linked to signaling pathways that were not previously known to be involved in pathogenesis, pointing to new directions in the study of disease mechanisms. GWAS also provided fundamental evidence for a key role of the immune system in the pathogenesis of these diseases, because many of the identified loci map to genes involved in different immune processes. However, the mechanisms by which disease-associated genetic variants act on disease development and the targeted cell populations remain poorly understood. The challenge of the post-GWAS era is to understand how these variants affect pathogenesis, to allow translation of genetic data into better diagnostics and innovative treatment strategies. Here, we review recent results that document the importance of the IL-23/IL-17 pathway for the pathogenesis of several chronic inflammatory diseases and summarize data that demonstrate how therapeutic targeting of this pathway can benefit affected patients.

Infrapatellar peripheral neural tumors, particularly neurofibromas, are rather rare entities reported in the literature. They are slow-growing lesions that usually do not exhibit clinical manifestations other than interspecific swelling or pain; hence, their diagnosis can be quite challenging. Therefore, scrutiny should include not only traditional clinical assessment and imaging but also more specific molecular biology techniques, such as immunohistochemistry.

The prevalence of perioperative anaphylaxis is 1 in 1250-20,000 anesthetics. Inhalational anesthesia is considered safe in patients with multiple drug allergies, as there have been no reports of anaphylaxis to volatile inhalational agents. Anesthetic management of six patients with documented allergy to all commonly used anesthetic drugs who underwent major surgeries under general anesthesia is described as a case series. The plan of anesthesia in these patients was an anesthetic gas-based general anesthesia without using muscle relaxants but with the use of intravenous fentanyl if patient was not allergic to it. Sevoflurane 8% in oxygen was used for induction. Following cessation of breathing and on attaining an end-tidal concentration of >4% sevoflurane, direct laryngoscopy and intubation were performed. Anesthesia was maintained with sevoflurane in nitrous oxide and oxygen mixture maintaining a lower end-tidal carbon dioxide. Hypotension and/or bradycardia were managed with intermittent intravenous boluses of adrenaline 20 μg. At the end of surgery, all anesthetic gases were cutoff, and patients were extubated when awake. No muscle relaxant was used in any of the cases. Two patients received fentanyl before induction, whereas others were given oral paracetamol 2 h before induction. Postoperative analgesia was provided with oral paracetamol which was given 2-4 h after surgery. Intraoperative period was uneventful for these patients. In patients with multiple drug allergies, inhalational agent-based general anesthesia can be considered as a safe alternative to regular anesthetic practice involving polypharmacy, with a reduced risk of perioperative adverse events.

Cholangitis in patients with ulcerative colitis (UC) can lead to misdiagnosis of primary sclerosing cholangitis (PSC). Furthermore, it can mimic cholangiocellular carcinoma, which also can lead to inappropriate and potentially harmful treatment of the patient. An 18-year-old male patient with known UC presented with pain in his right upper abdomen and elevation of the cholestatic liver enzymes (alkaline phosphatase: 197 U/L, γ-glutamyltransferase: 229 U/L) and increased inflammatory parameters (leukocytosis and CrP of 13.6 mg/L). Magnetic resonance cholangiopancreatography revealed unclear stenosis in the bifurcation of the main hepatic bile duct as well as in the prepapillary bile duct. Ultrasound (US) examination and endoscopic retrograde cholangiopancreatography showed dilatation of the intra -and extrahepatic bile ducts, which raised the suspicion of PSC. US image with dilated intra- and extrahepatic dilatation of the bile duct was also suggestive for autoimmune cholangitis. However, serum analysis revealed an elevated soluble interleukin-II receptor (1,305 U/mL), while immunoglobulin G4 was within normal ranges. Liver biopsy demonstrated hepatic inflammation and presence of granulomatous cells within the portal fields – convenient to sarcoidosis. After starting treatment with steroids, we observed a rapid clinical response with improvement of the dilated bile ducts and decrease of the initially elevated cholestatic liver enzymes. Sarcoidosis within the bile duct is a rare condition. Steroids are the treatment of choice and – along with the histology – are furthermore helpful to differentiate between several potential differential diagnoses like IgG4 cholangitis, primary biliary cholangitis, or PSC.

Research on learning in placebo and nocebo has relied predominantly on Pavlovian conditioning procedures. Operant learning procedures may more accurately model learning in real-life situations in which placebo and nocebo effects occur.
