- Lower extremity characteristics in recurrent clubfoot: Clinical and gait analysis findings that may influence decisions for additional surgery. [Journal Article]Gait Posture 2019; 75:85-92GP
- CONCLUSIONS: Patients with recurrent clubfoot show gait deviations at the ankle that can be explained by joint level impairment and compensations at the knee, hip and pelvis. Patients with unilateral clubfoot typically show decreased dorsiflexion range of motion and associated greater gait impacts and compensations than bilateral clubfoot. Understanding the relationships between impairments and gait function and the implications of unilateral versus bilateral clubfoot will help improve prognostic ability and optimize future treatment outcomes.
- [Mid-term and long-term results of metal-on-metal total hip arthroplasty]. [Journal Article]Khirurgiia (Mosk) 2019; (10):55-61K
- CONCLUSIONS: There was no correlation between female sex, young age of patients and incidence of complications. It is necessary to exclude pseudotumor in case of pain syndrome and no signs of aseptic loosening of the components of the endoprosthesis.
- [Morphological and immunohistochemical characteristics of the molecular subtypes of urothelial carcinomas]. [Journal Article]Arkh Patol 2019; 81(5):35-44AP
- CONCLUSIONS: Most pT1 tissues correspond to Molecular Class II. In the muscle-invasive urothelial carcinoma group, the neoplasms with a luminal phenotype predominate over the tumors with basal and neuronal phenotypes.
- Role of positioning between trunk and pelvis in locomotor function of ambulant children with and without cerebral palsy. [Journal Article]Ideggyogy Sz 2019; 72(9-10):343-351IS
- CONCLUSIONS: We conclude that, for the same locomotor level, there are no common postural patterns between children with typical development and those with spastic bilateral cerebral palsy for the position between trunk and pelvis in the sagittal plane. Maximal lordosis reduction between trunk and pelvis may change with age or even training, but does not make a positive effect on the locomotor level, while basal and maintenance capacities could explain locomotor function. Trials that failed to assess quality of movement may now have a better understanding of how different interventions improve posture towards the next functional level.
- Primary renal synovial sarcoma: A case report. [Case Reports]World J Clin Cases 2019; 7(19):3098-3103WJ
- CONCLUSIONS: PRSS is a rare malignant tumor. To date, no characteristic imaging findings have been observed. The diagnosis is confirmed primarily through postoperative pathological immunohistochemistry and SS18 (SYT) gene detection. In this case, CEUS was used preoperatively. We found that PRSS has the characteristic of "slow in and fast out" hyperenhancement, and its particular characteristics have diagnostic value. Postoperative adjuvant chemotherapy is not very effective.
- Correlation of tilt of the anterior pelvic plane angle with anatomical pelvic tilt and morphological configuration of the acetabulum in patients with developmental dysplasia of the hip: a cross-sectional study. [Journal Article]J Orthop Surg Res 2019; 14(1):323JO
- CONCLUSIONS: The tilt of the pelvis may be more dependent on anatomical-PT, a morphological parameter of the pelvis, than the lateral CE angle, anterior CE angle, posterior CE angle, and acetabular anteversion on bony coverage of the acetabulum. This study is the first to investigate the correlation between functional parameters of the pelvis and spine and morphological parameters of the pelvis and acetabulum besides PI.
- Validation of a method to measure three-dimensional hip joint kinematics in subjects with femoroacetabular impingement. [Journal Article]Hip Int 2019; :1120700019883548HI
- CONCLUSIONS: This 3D to 2D registration method may offer a clinically useful solution for dynamic assessment of hip impingement. If 5-mm translation and 10° of rotation represent a clinically significant difference in hip kinematics, the method's accuracy of approximately 1 mm displacement and 1° rotation should enable detection of significant clinical differences.

Background and Objectives: To determine the value of diuretic ultrasonography for the diagnosis of obstructive hydronephrosis. Materials and Methods: Diuretic enhanced ultrasonography was used routinely as a part of examination of patients with hydronephrosis in our Department. There were 72 patients (42 males, 30 females; aged 2 months to 17 years; median age 7.07 years) with a sonoscopic diagnosis of hydronephrosis included from January 2006 until October 2011. The anteroposterior diameter (AD) of renal pelvis was measured sonoscopically before and at sixty minutes after furosemide injection. A weight-adjusted dose of 1 mg/kg of furosemide was administered intravenously. Results: Patients were operated on if pyeloureteral obstruction was suspected because of low or deteriorating differential renal function, increasing hydronephrosis or symptoms thereof. Hydronephrosis was unilateral in 61 (84.7%) and bilateral in 11 (15.3%) patients. The median AD of pelvis before furosemide injection was 22 mm in operated and 17 mm in non-operated patients (p = 0.005). Sixty minutes after furosemide injection, the AD of pelvis in operated patients was 35.5 mm and 25.8 mm in non-operated-25.8 mm (p < 0.001). Logistic regression model demonstrated that significant factors for surgery were: AD 60 min after furosemide infection and ultrasonographic parenchymal sclerosis. Conclusion: Ultrasound measurement of the AD of renal pelvis 1 h after the injection of furosemide used as an additional investigation can help in predicting obstructive hydronephrosis.

Wearable electronics are recognized as a vital tool for gathering in situ kinematic information of human body movements. In this paper, we describe the production of a core-sheath fiber strain sensor from readily available materials in a one-step dip-coating process, and demonstrate the development of a smart sleeveless shirt for measuring the kinematic angles of the trunk relative to the pelvis in complicated three-dimensional movements. The sensor's piezoresistive properties and characteristics were studied with respect to the type of core material used. Sensor performance was optimized by straining above the intended working region to increase the consistency and accuracy of the piezoresistive sensor. The accuracy of the sensor when tracking random movements was tested using a rigorous 4-h random wave pattern to mimic what would be required for satisfactory use in prototype devices. By processing the raw signal with a machine learning algorithm, we were able to track a strain of random wave patterns to a normalized root mean square error of 1.6%, highlighting the consistency and reproducible behavior of the relatively simple sensor. Then, we evaluated the performance of these sensors in a prototype motion capture shirt, in a study with 12 participants performing a set of eight different types of uniaxial and multiaxial movements. A machine learning random forest regressor model estimated the trunk flexion, lateral bending, and rotation angles with errors of 4.26°, 3.53°, and 3.44° respectively. These results demonstrate the feasibility of using smart textiles for capturing complicated movements and a solution for the real-time monitoring of daily activities.

- Giant pelvic abscess with sepsis: Case report and review of current literature. [Journal Article]Int J Surg Case Rep 2019; 64:85-88IJ
- CONCLUSIONS: Pelvic abscesses are commonly due to gastrointestinal, genitourinary, post-surgical, or rarely idiopathic causes. US, CT, or MRI are the imaging modalities effective in diagnosing and staging abscess severity. Currently percutaneous, image-guided abscess drainage is the primary management due to it being minimally invasive, having better outcomes and reduced hospital stay. In large, multi-loculated abscess as exhibited by our patient, open surgical drainage and debridement of the infected cavity was not only successful but imperative in effective resolution.Most pelvic abscesses can be treated with percutaneous drainage but those complicated by necrotizing fasciitis, or multi-loculated collections may be better treated with open drainage.
