Recurrent Giant Pseudopolyp: Case Report and Review of the Literature.

we report the case of a recurrent giant pseudopolyp occurring in a patient without a history of inflammatory bowel disease (IBD), with an asymptomatic interval of nine years. Case Presentation: a 51-year-old Caucasian male with no relevant medical history was hospitalized for a subocclusive mass in the right colon, suspected to be neoplastic. He underwent a right hemicolectomy, and the histopathology revealed a giant pseudopolyp without malignancy.

An adjoint-based approach for the surgical correction of nasal septal deviations.

Deviations of the septal wall are widespread anatomic anomalies of the human nose; they vary significantly in shape and location, and often cause the obstruction of the nasal airways. When severe, septal deviations need to be surgically corrected by ear-nose-throat (ENT) specialists. Septoplasty, however, has a low success rate, owing to the lack of suitable standardized clinical tools for assessing type and severity of obstructions, and for surgery planning.

Nodal staging with MRI after neoadjuvant chemo-radiotherapy for locally advanced rectal cancer: a fast and reliable method.

Objectives: In patients with locally advanced rectal carcinoma (LARC), negative nodal status after neoadjuvant chemoradiotherapy (nCRT) may allow for rectum-sparing protocols rather than total mesorectal excision; however, current MRI criteria for nodal staging have suboptimal accuracy. The aim of this study was to compare the diagnostic accuracy of different MRI dimensional criteria for nodal staging after nCRT in patients with LARC.

Materials And Methods: Patients who underwent MRI after nCRT for LARC followed by surgery were retrospectively included and divided into a training and a validation cohort of 100 and 39 patients, respectively.

Importance of the numerical schemes in the CFD of the human nose.

Computational fluid dynamics of the air flow in the human nasal cavities, starting from patient-specific Computer Tomography (CT) scans, is an important tool for diagnostics and surgery planning. However, a complete and systematic assessment of the influence of the main modelling assumptions is still lacking. In designing such simulations, choosing the discretization scheme, which is the main subject of the present work, is an often overlooked decision of primary importance.

Through The Back Door: Expiratory Accumulation of SARS-Cov-2 in the Olfactory Mucosa as Mechanism for CNS Penetration.

SARS-CoV-2 is a respiratory virus supposed to enter the organism through aerosol or fomite transmission to the nose, eyes and oropharynx. It is responsible for various clinical symptoms, including hyposmia and other neurological ones. Current literature suggests the olfactory mucosa as a port of entry to the CNS, but how the virus reaches the olfactory groove is still unknown.

Review of a non-epithelial tumour of the small bowel after c-kit revolution.

Unlabelled: In this article, we reviewed the case of a patient who was object, in 1999, of a published case report of schwannoma of the jejunal wall. Recently, the patient has been referred to our institution for a mass of the stomach identified by upper gastrointestinal endoscopy. The patient underwent a wedge resection of the stomach and a histopathological diagnosis of GIST of the stomach, based on a positive immunohistochemical staining of c-kit and CD34, was made.

Common-mode rejection in Martin-Puplett spectrometers for astronomical observations at millimeter wavelengths.

The Martin-Puplett interferometer (MPI) is a differential Fourier transform spectrometer that measures the difference between spectral brightness at two input ports. This unique feature makes the MPI an optimal zero instrument, able to detect small brightness gradients embedded in a large common background. In this paper, we experimentally investigate the common-mode rejection achievable in the MPI at millimeter wavelengths, and discuss the use of the instrument to measure the spectrum of cosmic microwave background anisotropy.

[Abdominal CSF pseudocyst recurrence in a 14-year-old patient with ventricular-peritoneal shunt].

Abdominal cerebrospinal fluid (CSF) pseudocyst is a rare complication of ventricular-peritoneal shunt (VPS) but needs to be considered in every patient with abdominal complaints or signs of intracranial hypertension (IH). The pathogenesis of pseudocysts remains unclear. Diverse predisposing factors have been proposed such as previous abdominal surgeries, multiple VPS revisions, infections, history of necrotizing enterocolitis, and nonspecific inflammatory processes.
