#1
Nishant Jain, Vinod Kumar
In this paper, region-difference filters for the segmentation of liver ultrasound (US) images are proposed. Region-difference filters evaluate maximum difference of the average of two regions of the window around the center pixel. Implementing the filters on the whole image gives region-difference image. This image is then converted into binary image and morphologically operated for segmenting the desired lesion from the ultrasound image. The proposed method is compared with the maximum a posteriori-Markov random field (MAP-MRF), Chan-Vese active contour method (CV-ACM), and active contour region-scalable fitting energy (RSFE) methods...

Background: Available information on auxological attainments of symmetric and asymmetric SGA (small for gestational age) infants presents conflicting views. The complete absence of longitudinal data on growth patterns of both types of Indian SGA infants prompted us to undertake this study. Aim: To study distance and velocity growth pattern of weight and crown-heel length (CHL) of symmetric and asymmetric SGA infants. Subjects & Methods: Weight and CHL amongst full-term 100 symmetric SGA, 100 asymmetric SGA and 100 AGA infants from upper socio-economic strata were mixed-longitudinally measured at birth, 1, 3, 6, 9 and 12 months in the Department of Pediatrics, PGIMER, Chandigarh, India...

BACKGROUND: Ultrasound-guided fine-needle aspiration cytology (FNAC) is the standard modality for diagnosis of gallbladder malignant neoplasms. Adenocarcinoma is the most common malignancy; however, other types may also be encountered. The aim of this study was to perform a retrospective analysis of gallbladder malignancies diagnosed on FNAC in the last 5 years to document the cytomorphological spectrum and the variations thereof. METHODS: The records of the Department of Cytology, PGIMER were searched from July 2010 to June 2015 and all cases of gallbladder malignancies were analyzed in detail for cytomorphological characteristics...

PROBLEM STATEMENT: Neurosurgical patients require special care not only in the hospital but also after their discharge from the hospital. Comprehension and compliance to the instructions given by the doctors/nurses at the time of discharge is important in home care of these patients. Many such patients suffer from various co-morbidities. Variable periods of convalescence affect health-related quality of life in these patients. PURPOSE OF THE STUDY: To determine the degree of compliance of neurosurgery patients and their family caregivers with the discharge advice given by the consultantsTo evaluate the quality of life of these patientsTo know the problems faced by these patients at home...

OBJECTIVE: Fine needle aspiration (FNA) cytology is a relatively non-invasive method for diagnosing both superficial and deep-seated neoplastic and non-neoplastic lesions. In this study, we evaluated the diagnostic utility of trans-oral FNA in cervical (C1 and C2) vertebral and paravertebral lesions. MATERIAL AND METHODS: Eighteen FNA cases of cervical vertebral and paravertebral lesions performed by a trans-oral route without any image-guidance between 1995 and 2014 were retrieved from the archives of the cytology department at PGIMER, Chandigarh and reviewed...

BACKGROUND: Identification of aberrant antigen expression is important in characterizing neoplastic population among non.neoplastic bone marrow counterparts and further in the detection of minimal residual disease. (MRD). Flow cytometry (FCM) is an important tool in identifying aberrant phenotypes. Incidence of aberrant phenotypes varies considerably in independent studies and its association with prognostic factors is still debatable. AIM: To identify the prevalence of aberrant phenotypes on immunophenotyping in a large series of de novo acute lymphoblastic leukemia (ALL) and to evaluate any association with initial clinical and hematological features...

AIM: Children with human immunodeficiency virus (HIV) infection usually present with recurrent and unusual infections. Although reported among adults, arthritis as a predominant presentation in children with HIV is rare. Reactive arthritis is considered to be the most common musculoskeletal manifestation in adults with HIV infection. However, in children, septic or HIV-related arthritis has been described. We report four children having arthritis with HIV disease and their long-term outcome; out of which three had human leukocyte antigen (HLA)-B27-related arthritis...

UNLABELLED: During major liver resection, ischemia reperfusion injury occurs resulting in adverse outcome. Animal studies have demonstrated the beneficial effect of statins on hepatic ischemic injury, but no clinical studies have been performed. Twenty consecutive patients undergoing major hepatic resection were included and were randomized into two groups. The study group (n = 10) patients received oral atorvastatin 40 mg for 3 days prior to surgery, including the day of surgery, and the control group (n = 10) received a placebo...

BACKGROUND: Langerhans' cell histiocytosis (LCH) is a reactive proliferative disease of unknown pathogenesis characterized by proliferation of Langerhans cells. Involvement of bone marrow (BM), liver and lung are related to high risk factors and poor survival. The aim of this report is to highlight the clinical and haematological findings of 5 cases of LCH with BM infiltration which may help to predict involvement of BM. CASE SERIES: Five cases of Langerhan's cell histiocytosis with bone marrow infiltration were retrieved from archives of Department of Hematology, PGIMER and Chandigarh for review and further analysis...
