Spatio-Temporal Pattern of Tuberculosis Distribution in Romania and Particulate Matter Pollution Associated With Risk of Infection.

The study proposes a dynamic spatio-temporal profile of the distribution of tuberculosis incidence and air pollution in Romania, where this infectious disease induces more than 8,000 new cases annually. The descriptive analysis for the years 2012-2021 assumes an identification of the structuring patterns of mycobacterium tuberculosis risk in the Romanian population, according to gender and age, exploiting spatial modeling techniques of time series data. Through spatial autocorrelation, the degree of similarity between the analyzed territorial systems was highlighted and the relationships that are built between the analysis units in spatial proximity were investigated. By modeling the geographical distribution of tuberculosis, the spatial correlation with particulate matter (PM2.5) pollution was revealed. The identification of clusters of infected persons is an indispensable step in the construction of efficient tuberculosis management systems. The results highlight the link between the distribution of tuberculosis, air pollution and socio-economic development, which requires a detailed analysis of the epidemiological data obtained in the national tuberculosis surveillance and control program from the perspective of geographical distribution.

Increased femoral antetorsion correlates with higher degrees of lateral retropatellar cartilage degeneration, further accentuated in genu valgum.

PURPOSE: The role of increased femoral antetorsion (femAT) as a contributor to patellofemoral (PF) osteoarthritis (OA) is unknown. The purpose of this study was to investigate whether increased femAT was associated with advanced cartilage degeneration in the lateral PF joint. METHODS: Patients who underwent complete radiographic workup for surgical intervention due to OA in any knee joint compartment were included. Cartilage morphology according to the International Cartilage Repair Society (ICRS) cartilage lesion classification system in the PF joint, femoral and tibial torsion, frontal leg axis, and tibial tuberosity-trochlear groove (TT-TG) distance were assessed. Increased femAT was defined as > 20° according to previous reports. RESULTS: A total of 144 patients were included. Ninety-seven patients had a femAT of < 20° and 45 of > 20°. A significant odds ratio (OR) was found for lateral retropatellar (OR 3.5; p = 0.02) ICRS grade 3 and 4 cartilage degeneration and increased femAT ≥ 20°. In the medial PF compartment, increased femAT had an inverse effect (OR 0.16; p = 0.01). No significant ORs were found for TT-TG distance, tibial torsion, or leg axis. The lateral retropatellar ICRS grade showed a linear correlation to increased femAT values. In valgus knees, isolated lateral PF OA had an even more pronounced correlation to increased femAT (p = 0.004). CONCLUSION: Increased femAT showed higher grades of lateral retropatellar cartilage degeneration, which was even more pronounced in valgus knees. LEVEL OF EVIDENCE: Cohort study: Level III.

Recent advances in the surgical treatment of malunions in hand and forearm using three-dimensional planning and patient-specific instruments.

Malunions of the forearm and hand cause significant disability. Moreover, intraarticular deformities may contribute to early onset osteoarthritis. Such conditions require precise surgical correction in order to improve functional outcomes and prevent early or late complications. The purpose of this study was to describe the technical advantages of accurate anatomical reconstruction using 3D guided osteotomies and patient specific instruments (PSI) in multiple joints of the hand and forearm. Acquisition of three-dimensional (3D) datasets and surgical implementation of PSI was performed in a series of patients between December 2014 and July 2017. Patients had intra- or extra-articular malunions of the forearm, radiocarpal joint, trapeziometacarpal joint, or proximal interphalangeal joint. A previously described 3D surface model that incorporates CT data was used for segmentation (Mimics®, Materialise™, Belgium). For all the cases, CT scans of both forearms were acquired to use the contralateral uninjured side as the anatomic reconstruction template. Computer-assisted assessment of the deformity, the preoperative plan, and the design of PSI are described. Outcomes were determined by evaluating step-off correction, fusion, changes in range of motion (ROM) and grip strength. Six patients were included in the study; all achieved fusion. Improved clinical outcomes including pain reduction, better ROM and grip strength were obtained. Complete correction of intraarticular step-off was achieved in all cases with intraarticular malunions. 3D guided osteotomies are an established surgical treatment option for malunions of the hand and forearm. 3D analysis is a helpful diagnostic tool that provides detailed information about the underlying deformity. PSI can be developed and used for surgical correction with maximal accuracy for both intraarticular step-off and angular deformity.

Considerations on risk factors correlated to the occurrence of gastric stump cancer.

Gastric stump cancer (GSC) is the malignant tumor that develops in the gastric remnant after partial gastrectomy was performed both for benign and malignant lesions. This paper presents the results of the case studies from the scientific literature, which focused on GSC, and has been published in the last 10 years. The search was performed with the help of the specific tools offered by the international databases. The subject was approached because of the constant rising incidence of GSC in the past few years, now reaching values between 1% and 7%. The outcome report is consistent and similar to the period that ended approximately 25 years ago, when general surgeons dedicated a significant part of their activity to treating gastric ulcer. Statistics revealed that the main risk factors are the following: the type of reconstruction after distal gastrectomy (Billroth I or Billroth II), the presence of duodenogastric reflux, the time between gastric resections, and the moment of diagnosis of gastric stump cancer, the initial pathology for which partial gastrectomy was performed, gender, age, helicobacter pylori infection, Epstein Barr virus infection and the presence of vagotomy.

Esophageal disorders in mixed connective tissue diseases.

Extra Musculoskeletal manifestations are a distinct clinical entity that refers to a combination of clinical features, which are found in multiple rheumatic diseases. Besides the standard manifestations, other organs can be damaged such as the vascular system, skin, gastrointestinal tract, musculoskeletal system, cardiopulmonary system, hematologic system, kidneys, and the central nervous system. Among the gastrointestinal MCTD symptoms, the most frequent are the esophageal ones. Treatment of patients with MCTD must be performed by both medical and surgical multidisciplinary teams in order to provide a management suitable for the patients' needs. All authors have contributed significantly and have been involved in the writing of the manuscript in draft and any revision stages, and have read and approved its final version.

OUTCOME OF INTERNAL HEMIPELVECTOMY IN A PATIENT WITH MULTIPLE MYELOMA--CASE REPORT.

A patient treated for thyroid cancer was diagnosed with multiple myeloma in the context of trauma. After the pelvic tumor devascularization she underwent internal hemipelvectomy Type I + IIA Enneking Classification using polymerizing bioneutral gel embolization, "Glubran 2". The purpose of this case report is to demonstrate the importance of careful selection of treatment methods, together with adequate physical therapy in order to obtain favorable long-term results.
