BACKGROUND:  Patients undergoing deep vein thrombosis (VT) have over 30% recurrence, directly increasing their risk of post-thrombotic syndrome. Current murine models of inferior vena cava (IVC) VT model host one thrombosis event. OBJECTIVE:  We aimed to develop a murine model to study IVC recurrent VT in mice. MATERIALS AND METHODS:  An initial VT was induced using the electrolytic IVC model (EIM) with constant blood flow. This approach takes advantage of the restored vein lumen 21 days after a single VT event in the EIM demonstrated by ultrasound...

Hypercalcemia can be hazardous during pregnancy, most cases being due to primary hyperparathyroidism. We report a case of hypercalcemia with suppressed PTH levels necessitating treatment with bisphosphonates during pregnancy. A 38-year-old woman at the 26th week gestation was admitted because of symptomatic hypercalcemia. She did not take any medication that could influence her calcium levels. Physical examination was unremarkable. Laboratory tests on admission were: calcium 12.7 mg/dL (8.5-10.5 mg/dL), phosphorus 1...

Objective: Cesarean scar pregnancy (CSP) is a rare condition that occurs when the pregnancy implants in a cesarean scar. An early diagnosis and a proper management are fundamental to prevent maternal complications. We review and discuss the different treatment employed in our unit to reduce morbidity, preserve fertility, and predict possible complications. Methods: The reported treatment has been expectant management, operative hysteroscopy approach, and intramuscular injection of 50 mg methotrexate (MTX), followed by cervical dilation and manual vacuum aspiration (D&S) with a Karman cannula under ultrasound guidance, uterine artery embolization (UAE), and manual vacuum aspiration under ultrasound guidance and uterine artery embolization before surgical laparotomic resection...

Background: Isolated superior mesenteric vein (SMV) thrombosis is a rare but potentially fatal condition if untreated. Current treatments include transjugular or transhepatic approaches for rheolytic mechanical thrombectomy and subsequent infusions of thrombolytics. Tissue plasminogen activator (t-PA) power-pulse spray can provide benefit in a single setting without thrombolytic infusions. Computed tomography (CT) guidance for portal vein access is underutilized in this setting. Materials and Methods: Case 1 discusses acute SMV thrombosis treated with rheolytic mechanical thrombectomy alone using ultrasound guidance for portal vein access...

Cellulose nanocrystals (CNCs) were obtained from grape pomace through chemical and physical pretreatments. Bleached cellulose pulp was subjected to acid hydrolysis (AH) for 30 or 60 min and an ultrasound treatment to obtain CNCs (AH30S and AH60S ). Compositional analyses of untreated (UGP) and pretreated (PGP) grape pomace showed the effectiveness of pretreatment in removing non-cellulosic components, recovering 80.1% cellulose in PGP (compared to 19.3% of UGP). Scanning and transmission electron microscopies were used to evaluate the CNCs morphology...

Current urate-lowering therapy (ULT) includes three direct acting drugs (allopurinol, febuxostat, Rasburicase) and at least four 'indirect' drugs with other important targets (canagliflozin, losartan, fenofibrate and sevelamer). Moreover, the alcalinization of urines using bicarbonate can be used to dissolve urate crystals and the clinician may discontinue several drugs are known to increase serum levels of uric acid, such as diuretics, aspirin, cyclosporine, theophylline, mycophenolate and ACE inhibitors. While there is a consensus to start ULT in cases of symptomatic hyperuricemia (gout, urate-nephrolithiasis), the very frequent conditions of asymptomatic hyperuricemia remains a major conundrum...

BACKGROUND: Cryptococcosis is an important opportunistic infection of organ transplant recipients. It is the third most common fungal infection of transplant patients and occurs especially in kidney recipients. Cryptococcus neoformans is a ubiquitous fungus which infects humans by inhalation of spores. C. gattii has more recently been recognised as a pathogen. Infection commonly is disseminated affecting mainly the central nervous system and the lungs. Cryptococcoma, a localised form of the disease, has been described in various organs...

OBJECTIVE: The anticancer effect of myo-inositol (MI) is catching researchers' attention worldwide. Thyroid nodules (TNs) have been detected by ultrasound (US) in up to 76% of the general population and, although most of them are benign, thyroid cancer is the most common malignancy of the endocrine system. PATIENTS AND METHODS: A retrospective, observational study was conducted in 642 patients with suspected hypothyroidism undergoing US. The analysis was addressed exclusively to patients with subclinical hypothyroidism (SCH) or thyroid-stimulating hormone (TSH) levels borderline associated to TNs classified as class I and II; 1 group (control, no...

Azoospermia can be diagnosed in about 10%-15% of the infertile male population. To overcome the problem of failure to produce spermatozoa in the ejaculate in patients with nonobstructive azoospermia (NOA), testicular sperm extraction (TESE) may be performed to find the focal area of spermatogenesis. A 47-year-old man with NOA presented for treatment of secondary couple infertility. The patient underwent a first TESE 7 years earlier with cryopreservation, and an intracytoplasmic sperm injection-embryo transfer ended in a term pregnancy...

Ultrasound findings in autoimmune hepatitis (AIH) have not been reported systematically so far. The use of reliable and accurate noninvasive methods for determining fibrosis stage is important in evaluation of treatment efficacy and fibrosis regression in AIH. Imaging plays an important role in detection of complications and ruling out other possible causes of chronic liver diseases. Ultrasound elastography cut-off values in AIH patients are not the same as those in patients with chronic viral hepatitis or non-alcoholic fatty liver disease...

Developing the skills to adequately assess nail lesions in psoriasis is mandatory for correct interpretation of the pathological features and to provide correct management of psoriatic patients. Although clinical assessment is part of an accurate diagnosis of nail psoriasis, recent advances in the field of imaging are generating growing interest among clinicians exploring its potential role for the assessment of nail psoriasis. We would like to address the attention to ultrasound (US), which is having an impact in different clinical scenarios such as diagnosis, prognosis, and treatment monitoring of nail involvement in psoriatic disease...

Zhong Chen, Hongzhi Zhao, Xueyan Qiao, Cuo Yi, Shunji Gao, Wenhong Gao, Zheng Liu
Microbubble-enhanced ultrasound (MEUS) can non-invasively disrupt and block liver blood perfusion. It may potentially overcome the heat sink effect during a thermal ablation and consequently enhance radiofrequency ablation (RFA) of the liver. We propose a new strategy combining RFA with MEUS. For ultrasound treatment, an 831-kHz air-backed focused transducer directed 400-cycle bursts at 4.3 MPa to the liver at a 9-Hz rate. The treatment was nucleated by a lipids microbubble forming MEUS. Eighteen surgically exposed rabbit livers were treated using MEUS combined with RFA; the other 32 livers were treated using MEUS (n = 14) or RFA (n = 18) alone and served as the controls...
