BACKGROUND: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures. METHODS: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL. RESULTS: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage...

1,3-β-D-glucan (BG), a cell-wall component of most fungi including Pneumocystis (PC), is recommended by international guidelines for screening for pneumocystis pneumonia (PCP) in hematologic patients. We retrospectively validated the BG test in our tertiary university hospital. Forty-five patients (median age 53 years, 33% female) tested for PC by polymerase chain reaction (PCR) and/or immunoflourescence (IF)-microscopy with a stored blood sample within ±5 days of the PC test were tested by the Fungitell (cutoff <60 and >80 pg/ml)...

Establishing venous access in chronic dialysis patients is conducted by the insertion of polytetrafluoroethylene arterial-venous (AV) grafts. The continual access of these grafts allows for potential failure over extended periods of hemodialysis treatment, as a result of thrombosis and pseudoaneurysm formation. Patency of AV grafts requires interventional management of thrombosis and pseudoaneurysm formation, including thrombectomy and covered stent placement, respectively. In 2013, the Food and Drug Administration approved the Gore REVISE study, giving indication for covered stents within AV grafts...

OBJECTIVE: Somatostatin receptor (SSTR) expression constitutes a pivotal cornerstone for accurate radiological detection and medical treatment of small intestinal neuroendocrine tumors (SI-NETs), and the development of somatostatin analogues for these purposes have revolutionized the clinical work-up. Previous assessments of SSTR isoform expression in SI-NETs have found correlations to overall prognosis and treatment response, however these analyses usually report overall tumoral immunoreactivity, and little is reported regarding histo-regional differences in expressional patterns...

BACKGROUND: In case of high grade non-muscle invasive bladder cancer (HG-NMIBC), intravesical BCG represents the first-line treatment; despite the "gold" standard therapy, up to 50% of patients relapse, needing radical cystectomy. Hence, alternative therapeutic strategies have been developed. The aim of the study was to evaluate a first-line salvage treatment with EMDA®-MMC in patients with HGNMIBC unresponsive to BCG. METHODS: We carried out a prospective, single-center, single-arm Phase II study in order to evaluate the efficacy (in terms of recurrence and progression) and the safety of the EMDA®-MMC treatment in 26 (21 male, 5 female) consecutive patients with "BCG refractory" HGNMIBC on a 3 years follow-up...

Endometrial cancer is the most common gynaecologic malignancy in developed countries and its incidence is increasing. First-level treatment, if no contraindicated, is based on surgery. Pre-operative imaging is needed for evaluation of local extent and detection of distant metastases in order to guide treatment planning. Radiological evaluation, based on transvaginal ultrasound, MR and CT, can make the difference in disease management, paying special attention to assessment of entity of myometrial invasion, cervical stromal extension, and assessment of lymph nodal involvement and distant metastases...

BACKGROUND AND AIM: The progression of non-alcoholic fatty liver disease (NAFLD) to non-alcoholic steatohepatitis (NASH) is believed to be the driver for future development of fibrosis and cirrhosis. Nevertheless, there remains a clear deficit in non-invasive methods for the diagnosis of NASH. The aim of the present study was to evaluate the prevalence of portal lymphadenopathy (PL) in biopsy- proven NAFLD patients and to determine whether PL correlates with NAFLD stage and severity. METHODS: A retrospective study included biopsy-proven NAFLD patients with up to date (within one year) abdominal imaging by computed tomography (CT) and/or magnetic resonance imaging (MRI)...

In about 25-30% of patients with primary renal cell carcinoma, metastasis is not uncommon and usually does not give rise to difficulties in diagnosis. However, its presentation as a subcutaneous mass following an elapse of several years after the initial diagnosis is not only uncommon but may be also mistaken for a thrombus in imaging studies due to its common high vascularization. We present here a case of a 70-year-old woman with an oncologic history of renal cell carcinoma who noticed after five years a mass in the auricular region radiologically suggestive of a vascular thrombus...

Placenta accreta spectrum (PAS) disorders is a multifactorial process that encompasses a heterogeneous group of conditions characterized by an abnormal invasion of trophoblastic tissue through the myometrium and uterine serosa. PAS is associated with a high burden of adverse maternal outcomes including severe life-threatening hemorrhage, need for blood transfusion, damage to adjacent organs, and death. Prenatal screening of PAS is mandatory so that women may be counselled about the severity of this condition to plan management with a multidisciplinary team and delivery in a specialized center...

Discovery of small solid renal masses via echography, CT-scan or MRI is common in current medical practice, with more than 70 % found incidentally. Although they include benign lesions, most are renal cell carcinomas. A radiological assessment, associated if necessary with a percutaneous renal biopsy, leads to their diagnosis in the vast majority of cases. Minimally invasive partial nephrectomy has become the standard surgical technique in specialized centers. Ablative therapies (radiofrequency and cryotherapy) and active surveillance are other possible therapeutic approaches...

REVIEW
Mayumi Shimizu, Warangkana Weerawanich
Sonography is a simple, inexpensive, and non-invasive diagnostic modality. Although tissues behind bony structures and deep tissues are not delineated, sonography can depict superficial soft tissues very clearly. In the head and neck region, however, it has not yet been used widely, as the anatomical structures are complicated, and considerable experience is needed both to perform an examination and to make a diagnosis. To perform examinations efficiently, operators must be familiar with the sonographic system in use, and take images at standard planes...
