Objective: To evaluate the diagnostic performance of a rapid bedside 6-point lung ultrasonography (LUS) performed by an intensive care unit (ICU) physician for detection of four common pathological conditions of the lung, such as alveolar consolidation, pleural effusion, interstitial syndrome and pneumothorax, in critically ill patients and its comparison with bedside chest X-ray (CXR) and high-resolution computed tomography (CT) scan of the thorax. Volume of pleural effusion measured by LUS and CT thorax was also compared. Methods: This was a cross-sectional, observational study of 90 adult patients with an acute lung injury score of ≥1 admitted to the medical-surgical ICU. They were examined by CXR and 6-point LUS as per BLUE protocol at bedside, followed by CT thorax in the radiology department. Results: The sensitivity of 6-point LUS for detecting alveolar consolidation, pleural effusion, interstitial syndrome and pneumothorax was 76%, 88%, 83% and 89%, respectively, which was remarkably higher than that of CXR. The specificity of LUS was 100% for all pathologies, which was again notably higher than that of CXR except for interstitial syndrome for which it was 88.5%. Measurement of volume of pleural effusion by LUS was comparable and had a strong absolute agreement with CT thorax. Conclusion: 6-Point LUS can be a useful diagnostic tool and is better than CXR in diagnosing respiratory pathologies in critically ill patients. Owing to the comparable diagnostic performance of LUS and CT scan and with increasing evidence in favour of LUS, the requirement of CT thorax can be reduced. Radiation hazards associated with CXR and CT, as well as potentially risky transfer of patients to CT room, can also be minimised.

Background/Objective: Percutaneous biopsy (PB) and transjugular liver biopsy (TJLB) are 2 main ways of obtaining liver tissue. We evaluated the indications, success rate, tissue yield, and complications of TJLB in comparison to PB in children. Methods: Electronic records of children undergoing liver biopsy (LB) were reviewed. Clinico laboratory data including indication, type of biopsy, complications, and tissue yield (length and number of complete portal tracts [CPT]) were noted. Results: Five hundred forty LB (indication: neonatal cholestasis [42.9%], chronic liver disease [43.7%], liver failure [3.7%], focal lesions [3.3%] and others [6.3%]) were done. Four hundred seventy-three were PB (317 boys, 14 [1--216] months) done by percussion (322 [68%]), real-time ultrasound guidance (125 [26.4%]), or plugged method [26 (5.5%)]. Sixty-seven (12.4%) were TJLB [38 boys, 140 (24--216) months], done in patients with contraindications for PB. Technical success (67/68 vs 473/473; P = 0.7) and complications (4 [6%]; vs 15 [3.3%]; P = 0.2) of TJLB and PB were similar. Major complications (0.5%) included supraventricular tachycardia (n = 1) in TJLB and hemoperitoneum (n = 2) in PB. Tissue yield of TJLB was poorer in terms of length (1.0 [0.2--2.0] vs 1.1 [0.4--2.1] cm; P < 0.001), CPT (4 [0--9] vs 5 [2--17]; P < 0.001) and adequacy for reporting (56/67 vs 459/473; P < 0.001). Biopsy yield of <6 CPT was predicted by cirrhosis at histology and TJLB. No factor identified risk of complications with LB. Conclusions: LB is a safe procedure and only 12% children require TJLB because of contraindications of PB. Technical success and complications are similar but tissue yield is poorer in TJLB than PB. Presence of cirrhosis and TJLB adversely affected tissue yield.

Abdominal vibration is an effective method of reducing PVR in MS patients and appears more effective than abdominal pressure alone.

Aims:The aim of this study was to evaluate the safety and clinical efficacy of percutaneous direct needle puncture and transcatheter N-butyl cyanoacrylate (NBCA) injection techniques for the embolization of pseudoaneurysms and aneurysms of arteries supplying the hepato-pancreato-biliary (HPB) system and gastrointestinal (GI) tract.Subjects and Methods:A hospital-based cross-sectional retrospective study was conducted, where the study group comprised 11 patients with pseudoaneurysms/aneurysms of arteries supplying the HPB system and GI tract presenting to a tertiary care center from January 2015 to June 2016. Four patients (36.4%) underwent percutaneous direct needle puncture of pseudoaneurysms with NBCA injection, 3 patients (27.3%) underwent transcatheter embolization with NBCA as sole embolic agent, and in 4 patients (36.4%), transcatheter NBCA injection was done along with coil embolization.Results:This retrospective study comprised 11 patients (8 males and 3 females) with mean age of 35.8 years ± 1.6 (standard deviation [SD]). The mean volume of NBCA: ethiodized oil (lipiodol) mixture injected by percutaneous direct needle puncture was 0.62 ml ± 0.25 (SD) (range = 0.5–1 ml), and by transcatheter injection, it was 0.62 ml ± 0.37 (SD) (range = 0.3–1.4 ml). Embolization with NBCA was technically and clinically successful in all patients (100%). No recurrence of bleeding or recurrence of pseudoaneurysm/aneurysm was noted in our study.Conclusions:Percutaneous direct needle puncture of visceral artery pseudoaneurysms and NBCA glue injection and transcatheter NBCA injection for embolization of visceral artery pseudoaneurysms and aneurysms are cost-effective techniques that can be used when coil embolization is not feasible or has failed.

Introduction: Medullary thyroid carcinoma (MTC) is a malignant tumor of thyroid gland showing parafollicular or C-cell differentiation. Aims and objectives:The current study was undertaken to evaluate safety of ultrasound-guided thyroid fine-needle aspiration cytology (FNAC) and to assess cytomorphological features of MTC in FNA specimens from 28 patients. Materials and methods:The study was performed by retrospectively reviewing the clinical and pathological records of MTC cases managed at our institute. Results:The patients included 18 males and 10 females with a mean age of 45.3 years; 24 specimens were taken from thyroid, 15 from cervical lymph nodes and one each from liver space occupying lesion and chest wall nodule. There was no complication noted during ultrasound-guided FNAC in these patients. The smears had variable cellularity in the form of moderate cellularity in 63% of specimens and low cellularity in 15% of specimens. Cell arrangements were solid cohesive in 39% of cases and microfollicular clusters in 36% of cases. The frequent microfollicles in two specimens prompted the differential of follicular carcinoma. Dispersed population was noted in 90% of specimens. Binucleated and multinucleated cells were seen in 58 and 53% specimens respectively. Only spindle cell morphology was noted in 2% of specimens.
