Background And Aims: The insertion of central venous catheters (CVCs) is an integral part of the management of critically ill patients. We aimed to study the impact of ultrasonography (USG) on CVC insertion in intensive care.
Setting And Design: A prospective study of 450 patients requiring CVC in the intensive care unit (ICU) of a tertiary care hospital.
Methods And Materials: The patients were randomized into two groups: to have CVC insertion with USG-guidance or with the anatomic landmark technique (ALT). Data were collected on patient demographics; operator experience; and method, site and side of insertion. Outcome measures included successful insertion of CVC, number of attempts needed and complications.
Results: Internal jugular vein (IJV) cannulation was successful in 177/194 patients (91.2%) using ALT and in 200/205 patients (97.6%) using USG guidance, a significant difference of 6.4% (P = 0.006). Using ALT, 72.7% of cannulations could be accomplished in the first attempt as compared with 84.4% with USG guidance (P = 0.004). The overall complication rate was 28/399 (7%), with 19 (9.8%) complications in the ALT group and 9 (4.4%) in the USG group (age-, sex-, and operator-adjusted OR = 0.35, 95% CI: 0.13-0.96; P = 0.03). For subclavian vein catheterization, the success rate was 26/28 (92.9%) in the ALT group and 17/17 (100%) in the USG group (P = 0.52). Using ALT, 71.4% cannulation could be accomplished in the first attempt as compared with 82.4% under USG guidance (P = 0.49). The overall complication rate was 6/45 (13.3%), with 4 (14.3%) complications in the ALT group and 2 (11.8%) in the USG group (P > 0.99).
Conclusions: Real-time USG guidance improves success rates, reduces the number of attempts and decreases the complications associated with CVC insertion, especially for the IJV, and should become the standard of care in intensive care.

Background: Botulinum Toxin type A (BonTA) is the preferred treatment for Cervical Dystonia (CD). However, the success rate is often suboptimal. One of the reasons for treatment failure is the in accuracy of injections.

Introduction: Supraspinatus tendinopathy is a common reason for shoulder pain, with or without an associated cuff tear. Various modalities of treatment have been described in literature such as physiotherapy, analgesics, corticosteroid injection, surgical repair (open or arthroscopic), and platelet-rich plasma (PRP) injection. Recently, there has been an increasing trend of PRP injection for rotator cuff arthropathy.

Article Synopsis
- Hip osteoarthritis (OA) often requires pain management, and intra-articular corticosteroid injections (IACSI) are recommended, typically guided by ultrasound (USG) or fluoroscopy (FG), but it's unclear which method is better.
- A systematic review of studies on USG and FG IACSI was conducted, yielding eight studies with no direct comparisons between the two guidance techniques.
- The findings indicate both methods effectively reduce pain after one month, but network meta-analyses favored FG IACSI; however, more high-quality research is necessary to definitively choose a preferred technique.

Background Ultrasonography (USG)-guided fine-needle aspiration cytology (FNAC) of the liver is a primary diagnostic procedure for primary and metastatic hepatic lesions. Despite histopathology being the gold standard, the outcomes of ultrasound-guided fine needle aspiration cytology are encouraging. Aims and objective The purpose of the study is to determine the diagnostic utility of ultrasonography (USG) or computerized tomography (CT)-guided FNAC in the detection of liver lesions, to investigate cytomorphological patterns of liver lesions identified by guided FNAC, and, wherever feasible, to correlate FNAC diagnosis with histopathology and imaging modalities.

Image-guided thermal ablation is a minimally invasive option for patients with early-stage hepatocellular carcinoma (HCC). However, the risk of local recurrence remains substantial because ultrasound (US) artifacts have a negative impact on the assessment of ablative margins during and immediately after ablation. Precise, real-time assessment of the ablation zone is key to reducing the risk of local tumor progression.
