Objectives To present the value of office-based laryngological procedures as an effective alternative method to the treatment of benign and malignant laryngeal pathologies. Methods We have reviewed the technological advancements of fiber-guided laser systems, fiberoptic endoscopes, and high-definition imaging systems that have enabled office-based laryngological procedures. We describe the importance of case and patient selection, the available laser systems, and the technique applied. Results Several benign and malignant pathologies can be now treated in the office under local anesthesia with angiolytic or thermocoagulative lasers and with success rate comparable to that of general anesthesia. Safety guidelines and laser precautions must be implemented invariably to protect the patient and caregivers from the untoward effects of laser. Although there is considerable reduction of cost with office procedures, there are risks of undertreatment, increased repeatability, as well as tissue edema from the burning effect. Conclusions The low learning curve, high patient satisfaction rate, and excellent results indicate that in-office laser procedures have become an effective weapon in our armamentarium.Myxoma is a benign myxoid tumor of connective tissue that develops primarily in the heart. Epertinib At the level of the external auditory canal, it is extremely rare. It can be isolated or associated with Carney syndrome. Only 5 cases of isolated myxoma of the external auditory canal have been reported in the literature. We present the case of a 53-year-old patient who consulted for a hearing loss that has been evolving for 3 years. Otoscopy revealed a mass filling the external auditory canal. The scan showed a total filling of the external auditory canal with a homogenous sessile neoformation of 20 × 10 mm. This mass was completely resected and the histological examination showed spindle-shaped and star-shaped cells against an abundant myxoid background, which was consistent with myxoma. All the tests, done to eliminate Carney syndrome, did not reveal any abnormalities. The postoperative course was favorable, and no complications were noted. The patient was under follow-up. There was no recurrence 1 year after surgery.The scientific basis of intracranial aneurysm (IA) formation, its rupture and further development of cerebral vasospasm is incompletely understood. Aberrant protein expression may drive structural alterations of vasculature found in IA. Deciphering the molecular mechanisms underlying these events will lead to identification of early detection biomarkers and in turn, improved treatment outcomes. To unravel differential protein expression in three clinical subgroups of IA patients (1) unruptured aneurysm, (2) ruptured aneurysm without vasospasm, (3) ruptured aneurysm who developed vasospasm, we performed untargeted quantitative proteomic analysis of aneurysm tissue and serum samples from three subgroups of IA patients and control subjects. Candidate molecules were then validated in a larger cohort of patients using enzyme-linked immunosorbent assay. A total of 937 and 294 proteins were identified from aneurysm tissue and serum samples, respectively. Several proteins that are known to maintain structural integrity of vasculature were found to be dysregulated in the context of aneurysm. ORM1, a glycoprotein, was significantly upregulated in both tissue and serum samples of unruptured aneurysm patients. We employed a larger cohort of subjects (n = 26) and validated ORM1 as a potential biomarker for screening of unruptured aneurysms. Samples from ruptured aneurysms with vasospasm showed significant upregulation of MMP9, a protease, compared with ruptured aneurysms without vasospasm. We validated MMP9 as a potential biomarker for vasospasm in a larger cohort (n = 52). This study reports the first global proteomic analysis of the entire clinical spectrum of IA. Furthermore, this study suggests ORM1 and MMP9 as potential biomarkers for unruptured aneurysm and cerebral vasospasm, respectively.Organochlorine pesticides (OCPs) are widely used around the world as insecticides, herbicides, fungicides, nematicides, and rodenticides. Despite banned in Brazil, the usage remains occurring in many countries. The persistence and extreme mobility of OCPs contribute to the contamination of the environment and the human body. The OCPs bioaccumulation in adipose tissue triggers the excretion into human milk during breastfeeding. Hence, the present study determined eighteen OCPs residues in the breast milk of mothers from the Western Region of Bahia State, Brazil. Nine different residue species were found, including beta-Hexachlorocyclohexane (9.24 ± 0.00 ng g-1 fat), delta- Hexachlorocyclohexane (22.15 ± 10.48 ng g-1 fat), Heptachlor (58.08 ± 74.13 ng g-1 fat), Aldrin (142.65 ± 50.65 ng g-1 fat), Dieldrin (774.62 ± 472.68 ng g-1 fat), Endosulfan I (408.44 ± 245.51 ng g-1 fat), Dichloro-diphenyl-dichloro-ethylene (29.17 ± 22.42 ng g-1 fat), Dichloro-diphenyl-trichloro-ethane (28.87 ± 0.00 ng g-1 fat) and Methoxychlor (1699.67 ± 797.43 ng g-1 fat). The Methoxychlor presence in all samples may reveal a recent exposure, while Dieldrin and Endosulfan I analyses can point to distant past exposure.Background Tisagenlecleucel was approved for the treatment of pediatric and young adult patients with relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (ALL) based on the pivotal ELIANA trial. Objective To comprehensively evaluate the total costs associated with tisagenlecleucel treatment, including costs from pre- to postinfusion periods of tisagenlecleucel in addition to the cost of tisagenlecleucel. Methods An economic model was developed to estimate total costs associated with tisagenlecleucel treatment from the time of leukapheresis to 2 months postinfusion from a U.S. hospital's perspective. Costs were estimated based on resource use and safety management from the ELIANA trial and were considered during the pretreatment, tisagenlecleucel infusion, and follow-up periods of treatment. Cost components included leukapheresis, lymphodepleting chemotherapy, tisagenlecleucel infusion and hospital administration, inpatient and intensive care unit admissions, medical professional visits, laboratory tests and procedures, and management of major adverse events.
