Primary malignant bone tumors represent 5% of malignant tumors in children, 90% of which are osteosarcomas or Ewing sarcomas. The objective of oncological resection is local control of the disease. Excision of the entire tumor should make it possible to maintain good function of the limb, minimizing morbidity, and promoting acceptance by the patient. Biological reconstructions offer the best long-term functional results. Several possibilities are then available: the Induced Membrane technique, the Vascularized Fibula and Vascularized Fibula associated with an Allograft. Until today, no reconstruction technique in children has proven its superiority over another and no decision-making algorithm for therapeutic care has been determined based on the importance of the bone resection and the affected segment in diaphyseal tumor reconstruction surgery of the lower limb. The aim of the present research is to compare the three techniques concerning the consolidation aspect, the reoperation rates, the rates of bone complications, septic, and the functional results by the study of the medical files of approximately 90 patients operated between 1986 and 2017.
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive modality that utilizes electrical currents to modulate pain in populations with acute and chronic pain. TENS has been demonstrated to produce hypoalgesic effects in postoperative pain, fibromyalgia, knee osteoarthritis, and healthy subjects. Transcutaneous auricular vagus nerve stimulation (TaVNS) is a non-invasive modality that modulates the vagus nerve by stimulating its auricular branches. The effects of the combination of TENS and TaVNS on producing an analgesic response have not been studied. Considering that TENS and TaVNS both stimulate similar analgesic pathways but through different means of activation, the investigators can hypothesize that a combination of both methods can produce a more pronounced analgesic response. Therefore, the objective of this study is to assess the hypoalgesic effect of a combination of TENS and TaVNS in pain-free subjects. The study will be a simple crossover design conducted at the University of Hartford. Subjects will be recruited from the University of Hartford population via oral communication, digital flyers, and posters on campus. Thirty participants will undergo two sessions in a crossover manner with one week in between. During one session, the participants will receive TENS with active TaVNS and the other session will be a placebo procedure (TENS with placebo TaVNS). The order of these sessions will be randomized. Importantly, the pressure pain threshold (PPT) and heat pain threshold (HPT) assessors will be blinded to the treatment category. For active TaVNS, a frequency of 25 Hz will be applied with a pulse duration of 200 µs. For placebo TaVNS, the intensity will be increased to a sensory level and then decreased to 0 mA. High frequency TENS of 100Hz will be applied in both sessions, with a pulse duration of 200 µsec, asymmetrical biphasic square waveform, and intensity of maximal tolerance without pain. TENS and TaVNS will be turned on for 30 minutes after a baseline measurement of outcomes. TENS and TaVNS will then be turned off, but the electrodes will remain on until completion of post-treatment assessment. Pressure pain threshold, heat pain threshold, blood pressure, oxygen saturation and heart rate will be tested 4 times: Once pre-intervention, once during intervention, once immediately after the intervention and once 15 minutes post-intervention.

The main questions it aims to answer: Can Intermittent Nutritional Tube Supplementation help improve the nutritional status in Elderly Patients With Dysphagia. Participants will be divided into two groups randomly. All patients are given routine rehabilitation and the intervention group is given Intermittent Oro-esophageal Tube Feeding once a day.
The purpose of the research is to test the feasibility and preliminary impact of a home-based, standardized, gut-directed, virtual reality cognitive behavioral therapy (VR CBT) on clinical and functional outcomes of patients with chronic pancreatitis (CP) and recurrent acute pancreatitis (RAP) pain. The primary research procedures are questionnaires and biometric Fitbit data. The study will enroll adult patients with CP or RAP.
The goal of this clinical trial is to evaluate the value of 99mTc-CNDG for diagnosis of brain tumors by comparing it with 18F-FDG-PET. The main questions it aims to answer are: 1. What is the diagnostic consistency between 99mTc-CNDG and 18F-FDG? 2. What is the correlation between the SUVmax value of 99mTc-CNDG and tumor type? Participants will: Receive18F-FDG-PET and 99mTc-CNDG examination within 2 weeks before surgery. Obtain pathological diagnosis by surgery or biopsy as the gold standard.
Hemorrhoidal disease, characterized by symptomatic enlargement and distal displacement of anal cushions, has been a subject of recognition and management for centuries. The etymology of "hemorrhoid" is traced back to the Greek words haima (blood) and rhoos (flow). Prevalent in over 20% of the population across various life stages, this anorectal condition impacts both genders. The multifaceted development of the disease incorporates theories encompassing abnormal dilation of hemorrhoidal plexuses, distension of arteriovenous anastomoses, prolapse of anal pads, and a myriad of genetic, anatomical, dietary, and lifestyle factors. Manifestations range from venous distension to bleeding and thrombosis, with classification based on location (internal/external/combined) and degree of prolapse (grade 1-4). Upon comprehensive history-taking and examinations, including digital rectal and proctoscope assessments, a definitive diagnosis is established, leading to the treatment phase. Although outpatient procedures demonstrate efficacy, patients may persist with pain and discomfort. Medical intervention assumes significance for stages 1 and 2, incorporating approaches such as rubber-band ligation, injection sclerotherapy, and dietary modifications. Micronized Purified Flavonoid Fraction (MPFF), integral to hemorrhoid treatment, has been scrutinized for its ability to mitigate pathogenic processes culminating in acute bleeding. The stagnation of blood in vascular plexuses prompts an inflammatory response, activating white cells and increasing vessel wall permeability. MPFF's flavonoid compounds are posited to alleviate bleeding by augmenting venous tone, reducing stasis, inhibiting inflammatory mediators, and enhancing lymphatic drainage[8]. Multiple trials substantiate MPFF's efficacy in ceasing bleeding, alleviating symptoms, and preventing hemorrhoid relapse. Aescin, a saponin mixture found in Aesculus hippocastanum (horse chestnut). The primary active component, β-aescin, contributes to the plant's medicinal attributes. Experimental investigations in animal models underscore its anti-edematous, anti-inflammatory, and venotonic properties, attributed to molecular mechanisms facilitating ion entry into channels and elevating venous tension. While the therapeutic benefits of aescin for hemorrhoids are acknowledged, the absence of randomized control trials impedes the conclusive validation of its efficacy. In the realm of diverse treatment options, this proposed randomized controlled trial aims to assess the comparative effectiveness of combining aescin with MPFF versus MPFF alone in managing hemorrhoid-related symptoms. The study aspires to furnish valuable insights for refining therapeutic strategies in the management of hemorrhoids and enhancing patient outcomes.
In the management of patients with noncarious cervical lesions (NCCL), we observe that they frequently present signs of anxiety, traumatic brushing, bruxism or eating disorders. These multifactorial and interrelated etiologies make diagnosis and management difficult. Furthermore, in the literature, there is a lack of studies that evaluate the relationship between these risk factors and NCCL. A better understanding of the etiology and risk factors would help to optimize patient management and direct patients to the most appropriate therapies.
The goal of this pilot clinical trial is to evaluate a culturally tailored computerized education program in hospitalized African-American patients with advanced chronic kidney disease (CKD). The main question it aims to answer are: does computerized adaptive education (CAE) increase patients' knowledge about CKD self-care and renal replacement therapy (RRT) options compared to usual care (UC) and will CAE will be increase patients' intent to participate in CKD self-care and RRT preparation compared to UC
