There are about 3753 clinical studies being (or have been) conducted in Hong Kong. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
After obtaining informed consent, eligible subjects will be assigned randomly into either High intensity focused ultrasound group (HIFU) or Radioactive iodine (131I) therapy group (RAIT). After treatment, they will be followed up for 4 visits (1-month, 3-month, 6- month, 12-month of post treatment). At each visit, they will have physical examination, regular blood test and questionnaire to evaluate their quality of life. The collected data will be used to compare the effectiveness between HIFU and RAIT for non-toxic multi-nodular goiter (NMNG). The primary purepose is to find out the best non-invasive way in treating NMNG. For HIFU, you may experience: 1. Mild bruising and redness at the site of treatment 2. Edema of the skin tissue 3. Pain/discomfort during the procedure 4. Skin burns but rare (<1%) 5. Vocal cord paresis on the side of the treated lobe but rare (<1%) 6. Unintentional damage to the surrounding tissue (outside the planned treatment area). For RAIT, you may experience neck tenderness or sore throat in the following few days as developing moderate inflammation in the thyroid and producing discomfort in the neck or throat area. Your symptoms may turn worse for first few week, but will improve over weeks.
This study aims to explore the prevalence of demoralization among palliative care patients and family caregivers in Hong Kong and examines psychosocial factors associated with demoralization. We hypothesized that higher depression, caregiving strain and caregiver support needs would lead to higher demoralization, and greater perceived family support was associated with lower demoralization among patients and family caregivers.
The purpose of this study is to demonstrate how well aflibercept works in babies with ROP, comparing it with laser therapy. The study also has the objective to demonstrate how safe aflibercept is when used in babies, and describe how the drug moves into, through and out of the body.
Compare Customized arch support orthoses (CASO) and orthotic heel lift (HL) on the effect of ATL in recreational runners with pronated feet.
Brief advice combined with active referral to smoking cessation (SC) services increases quitting. We aim to strengthen the effect of combined intervention by using interactive communication technologies and nicotine replacement therapy sampling (NRT-S).
Medial open wedge high tibial osteotomy is a surgery performed to treat knee osteoarthritis in young patients.Recently with our department advance of technology, the investigators performed computed tomography for the patient's lower limb and 3D reconstruct the image. Based on the 3D image, the investigators planned our planned osteotomy cut on computer software Materialize 3 and the investigators then 3D printed a metal jig that has a slot to produce the osteotomy and also protected the neurovascular bundles. Therefore these metal jigs are specific to each patients. The investigators have performed a few cases of HTO under this extra metal jig protection and guidance and noted it has improved accuracy and safety clinically. However, whether it has scientific significance difference in accuracy is not known.
This study evaluates the clinical and biological effects of leucocyte and platelet-rich fibrin (L-PRF) on intraoral wound healing.
The purpose of this study is to explore the effects of pulsed dye laser on managing scar vascularity and thickness.
This study evaluates the clinical and biological effects of leucocyte and platelet-rich fibrin (L-PRF) on post-extraction sockets healing.
Whole body vibration (WBV) has been found to be useful in promoting bone health and muscle performance in older adults. To date, no study has examined the effects of different WBV frequencies on the properties of the muscle-bone unit in stroke patients. The overall aim of the proposed study is to compare the efficacy of different vibration frequencies on properties of the muscle function and bone turnover among people with chronic stroke. It is hypothesized that the higher-vibration frequency protocol will lead to significantly better outcomes related to the bone turnover and muscle function.
