cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...

identifying clusters or clustering is an important aspect of data analysis. it is the task of grouping a set of objects in such a way those objects in the same group/cluster are more similar in some sense or another. it is a main task of exploratory data mining, and a common technique for statistical data analysis this paper proposed an improved version of k-means algorithm, namely persistent k...

Purpose: Total knee arthroplasty (TKA) is the final treatment option for end-stage osteoarthritis. While it expected to resolve pain, 15-40% of patients have persistent pain 6 months after surgery that not otherwise explained (e.g., infection, joint loosening). majority undergo only one replacement, a substantial fraction has both knees replaced, and these are typically staged (performed sequen...

let ‎x be an ‎‎n-‎‎‎‎‎‎square complex matrix with the ‎cartesian decomposition ‎‎x = a + i ‎b‎‎‎‎‎, ‎where ‎‎a ‎and ‎‎b ‎are ‎‎‎n ‎‎times n‎ ‎hermitian ‎matrices. ‎it ‎is ‎known ‎that ‎‎$vert x vert_p^2 ‎leq 2(vert a vert_p^2 + vert b vert_p^2)‎‎‎$, ‎where ‎‎$‎p ‎‎geq 2‎$‎ ‎and ‎‎$‎‎vert . vert_p$ ‎is ‎the ‎schatten ‎‎‎‎p-norm.‎ ‎‎ ‎‎in this paper‎, this inequality and some of its improvements ...

objectives: joint attention is one of the most important prerequisite of language and social development. there are two types of joint attention, initiating joint attention and responding to joint attention. this study examined the development of responding to joint attention in typically developing children in 8-30 month. methods: this study was cross-sectional. 61 children (40 female and 20 m...

OBJECTIVES To study the morphological changes of the regenerating synovium in two-stage revision arthroplasty, which is the gold standard for treatment of periprosthetic joint infection. DESIGN The authors analysed a series of synovial biopsies to examine morphological changes in healing periprosthetic tissues damaged by previous surgery and infection. METHODS Synovial tissues from 19 patie...

BACKGROUND Persistent postoperative pain has a significant relationship with patient health and satisfaction. OBJECTIVES To investigate the prevalence and association of neglect-like symptoms (NLS) and other psychological factors on postoperative pain in patients following total knee arthroplasty (TKA). NLS are defined as the loss of perception of the limb with pain and excessive effort requi...

prosthetic joint infection (pji) is a serious complication of total knee arthroplasty (tka). control of infection after a failed two-stage tka is not always possible, and the resolution of infection may require an above-knee amputation (aka) or a the-knee (kf). the purpose of this review is to determine which treatment method (aka or kf) yields better function and ambulatory status for patients...

BACKGROUND Based on systematic reviews, it appears that at least 10% of patients may continue to suffer with residual or persistent pain after successful vertebral or sacral augmentation procedures. OBJECTIVE To report and evaluate the incidence and prevalence of different spinal injections in patients who received vertebroplasty, kyphoplasty, and sacroplasty procedures for both benign and ma...

A number of bacteria have been implicated as causing reactive arthritis. In epidemiological studies Chlamydia have been identified as the most common bacteria triggering reactive arthritis in Western countries. Only 1–3% of patients acquiring infection at the urogenital tract as the primary site of infection develop Chlamydia-induced arthritis. It has been shown that C trachomatis reaches the j...
