Diverticulitis of the vermiform appendix is a rare disease with clinical features often similar to conventional acute appendicitis. The importance of appendiceal diverticulosis is the fact that it can lead to an early and a higher incidence of perforation and therefore a higher mortality rate, in contrast to acute appendicitis alone. In this study we present the clinicopathology, diagnosis and therapy of the disease with a review of the literature. A 65-year-old woman presented to the emergency department with a 48-hour history of intermittent pain in the right iliac fossa...

Introduction: Congenital pulmonary malformations are a rare cause of neonatal morbidity. Some of them have a common origin, which allows the identification of combined lesions. Its diagnosis can be made prenatally by ultrasound, with the limitation that this study is performed in specialized centers and depends on the expertise of the operator. The association of pulmonary sequestration and congenital malformation of the airway has been described in approximately 40-60 cases since its first description in 1949...

There is no real need to discuss the potential advantages - mainly the excellent soft tissue contrast, nonionizing radiation, flow, and molecular information - of magnetic resonance imaging (MRI) as an intraoperative diagnosis and therapy system particularly for neurological applications and oncological therapies. Difficult patient access in conventional horizontal-field superconductive magnets, very high investment and operational expenses, and the need for special nonferromagnetic therapy tools have however prevented the widespread use of MRI as imaging and guidance tool for therapy purposes...

This Consensus Opinion summarizes the main aspects of several techniques for performing ovarian antral follicle count (AFC), proposes a standardized report and provides recommendations for future research. AFC should be performed using a transvaginal ultrasound (US) probe with frequency ≥ 7 MHz. For training, we suggest a minimum of 20-40 supervised examinations. The operator should be able to adjust the machine settings in order to achieve the best contrast between follicular fluid and ovarian stroma...

Advances in information and communications technologies provide a new opportunity to improve the access to healthcare in remote rural areas (RA) where there is a lack of infrastructure and medical experts. This paper implements a new model for tele-ultrasound (US) based on volumetric sweep imaging protocols specially designed for the acquisition of US. Non-physician health personnel from the RA are trained on the use of these protocols in a few days. The operator utilizes the medical box (MB), a specially designed telecommunication system, to guide, compress, encrypt and transmit the US sweeps through the cloud to the radiologist who performs the diagnosis remotely...

BACKGROUND: Carotid atherosclerosis is a powerful predictive factor of vascular risk at the individual patient level. Ultrasonography is a reference technique for the evaluation of this condition. However, its use in common practice remains difficult due to a lack of standardization and inter-operator variability. We present a new and simple technique for the assessment of carotid atherosclerosis; and evaluate the ability of vascular neurologists to obtain results consistent with those of an expert in vascular ultrasound...

Management of differentiated thyroid carcinoma (DTC) is gradually evolving with considerations of de-escalation of treatment and/or active surveillance in a significant proportion of patients on the basis of an improved understanding of the long-term disease and functional outcomes from both surgical and non-surgical approaches. This is fueled by improved risk stratification using clinicopathologic prognostic factors as determined through high resolution ultrasound and fine needle aspiration cytology. This paper discusses general recommendations for preoperative decision-making in the management of the central compartment in DTC with particular reference to micropapillary thyroid carcinoma and encapsulated follicular variant papillary thyroid carcinoma...

BACKGROUND Elizabethkingia meningoseptica (E. meningoseptica) is an aerobic Gram-negative bacillus known to thrive in moist environments, and is now recognized as a hospital-acquired infection, being found to contaminate hospital equipment, respiratory apparatus, hospital solutions, water, and drainage systems. Nosocomial infection with E. meningoseptica occurs in immunocompromised patients, requires specialized identification methods, and is resistant to conventional antibiotics. We report a case of E. meningoseptica infection arising from a percutaneous transhepatic biliary drainage (PTBD) tube...

Matthew Toews, William M Wells
This paper presents a method for automatically calibrating and assessing the calibration quality of an externally tracked 2-D ultrasound (US) probe by scanning arbitrary, natural tissues, as opposed a specialized calibration phantom as is the typical practice. A generative topic model quantifies the posterior probability of calibration parameters conditioned on local 2-D image features arising from a generic underlying substrate. Auto-calibration is achieved by identifying the maximum a-posteriori image-to-probe transform, and calibration quality is assessed online in terms of the posterior probability of the current image-to-probe transform...

Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly, characterized by hypertrophy of the mucosal epithelium that invaginates into the interstices of a thickened muscularis forming so-called Rokitansky-Aschoff sinuses. There are three forms of ADM: segmental, fundal and more rarely, diffuse. Etiology and pathogenesis are not well understood but chronic inflammation of the GB is a necessary precursor. Prevalence of ADM in cholecystectomy specimens is estimated between 1% and 9% with a balanced sex ratio; the incidence increases after the age of 50...

BACKGROUND: Despite advances in non-invasive radiological techniques for the treatment of intussusception, management of the entity still remains exclusively surgical in many developing countries, including Ethiopia. Fluoroscopic units are rare or mostly dysfunctional. Ultrasound scanners are more commonly available. Ultrasound-guided hydrostatic reduction (USGHR) was recently introduced to the main referral hospital in Ethiopia, and subsequently has been adopted as the initial management option for intussusception...
