Objective: To evaluate the feasibility, efficacy and safety of the percutaneous coronary intervention (PCI)guided by computed tomography (CT) coronary angiography derived roadmap and magnetic navigation system (MNS).
Methods: During June 2011 and May 2012, thirty consecutive patients receiving elective PCI were enrolled, coronary artery disease was primarily diagnosed by dual-source CT coronary angiography (DSCT-CA) at outpatient clinic and successively proved by coronary artery angiography in the hospital. Target vessels from pre-procedure DSCT-CA were transferred to the magnetic navigation system, and consequently edited, reconstructed, and projected onto the live fluoroscopic screen as roadmap. Parameters including characters of the target lesions, time, contrast volume, radiation dosage for guidewire crossing, and complications of the procedure were recorded.
Results: Thirty patients with 36 lesions were recruited and intervened by PCI. Among the target lesions, sixteen were classified as type A, 11 as type B1, 8 as type B2, 1 as type C. The average length of the target lesions was (22.0 ± 9.8) mm, and the average stenosis of the target lesions was (81.3 ± 10.3)%. Under the guidance of CT roadmap and MNS, 36 target lesions were crossed by the magnetic guidewires, with a lesion crossing ratio of 100%. The time of placement of the magnetic guidewires was 92.5 (56.6 - 131.3) seconds. The contrast volume and the radiation dosage for guidewire placement were 0.0 (0.0 - 3.0) ml and 235.0 (123.5 - 395.1) µGym(2)/36.5 (21.3 - 67.8) mGy, respectively. Guidewires were successfully placed in 21 (58.3%) lesions without contrast agent. All enrolled vessels were successfully treated, and there were no MNS associated complications.
Conclusions: It is feasible, effective and safe to initiate PCI under the guidance of CT derived roadmap and MNS. This method might be helpful for the guidewire placement in the treatment of total occlusions.

Lymphadenopathy is associated with lymph node abnormal size or consistency due to many causes. We employed the deep convolutional neural network ResNet-34 to detect and classify CT images from patients with abdominal lymphadenopathy and healthy controls. We created a single database containing 1400 source CT images for patients with abdominal lymphadenopathy (n = 700) and healthy controls (n = 700).

Background: Oral cancer screening programs can aid in the early identification of potentially malignant oral lesions. The objective of the present study was to evaluate the effectiveness of the Oral Rub and Rinse (ORR) technique as an oral cancer screening tool and to test its potential in detecting genetic alterations in exfoliated cells obtained through ORR.
Methods: The screening programs were conducted in rural Dakshina Kannada and Udupi districts in Karnataka.

Objective: To investigate the predictive value of tumor iodine concentration obtained with dual-energy CT (DECT) for treatment response in patients treated with immune checkpoint inhibitors (ICI).
Materials And Methods: Retrospective single-center study of consecutive metastatic melanoma and renal cell carcinoma (RCC) patients undergoing first-line ICI treatment. The iodine concentration measurement time points include prior to initiation of therapy (baseline [BL]), after initiation (follow-up [FU1]), and either time point nearest to 12 months or at time of progression (final follow-up [FFU]).

Visceral leishmaniasis (VL) is a vector-borne disease caused by the obligate intracellular protozoan in India. VL can be complicated by post-kala-azar dermal leishmaniasis (PKDL), a macular or nodular rash that develops in 10%-20% of patients after treatment of VL in India. Patients with PKDL are infectious to sand flies, promoting further transmission of the parasite.

To identify patients with infantile hemangioma (IH) in need of early-stage treatment in this multicenter, prospective, observational study, we investigated the potential of plasma cytokines as a clinically useful marker. Plasma samples were collected at three time points from 41 patients with infantile hemangioma: baseline (days 14-60 after delivery), visit 1 (days 61-150, the proliferative phase), and visit 2 (days 151-395, the involuting phase). With a twofold or more increase in tumor volume during the baseline-visit 1 period regarded as progression, progression was seen in 15 cases (36.
