This completed study tested two types of attachments (ball-and-socket vs Equator) for lower jaw implant-supported dentures in 24 adults aged 55-60. Researchers measured bone loss around the implants and how bite forces were distributed. The goal was to see which attachment provid…

This study looked at whether adding 1% metformin gel to a bone graft improves bone healing and implant stability in people getting immediate dental implants. Twenty adults aged 18 to 40 with a non-restorable tooth in the front or premolar area took part. The researchers measured …

This study compared a liquorice nanogel to a diode laser as extra treatments for advanced gum disease (stage III). 27 adults with deep gum pockets received one of the two treatments alongside standard care. The goal was to see which approach better reduced harmful bacteria and im…

This study tested a two-part surgery for children with severe constipation that didn't get better with standard treatments. The surgery removes part of the colon and creates a small opening in the belly for enemas. The goal was to reduce accidental stool leakage (soiling). The st…

This study compared two surgical methods for removing non-cancerous parotid gland tumors: a newer, less invasive technique called intracapsular parotidectomy (ICP) and the standard superficial parotidectomy (SP). Researchers wanted to see if ICP could reduce complications like fa…

This study tested whether adding cabergoline to letrozole helps women with PCOS ovulate better than letrozole alone. 100 women with PCOS took part. Researchers tracked ovulation using ultrasound. The goal was to find a more effective way to trigger ovulation in this common hormon…

This study tested a three-step treatment for people with muscle invasive bladder cancer: chemotherapy, then tumor removal through the urethra, then radiation. The goal was to save the bladder and improve quality of life compared to removing the bladder entirely. 97 patients took …

This study compared two surgical techniques to repair a torn back part of the knee's cushion (medial meniscus root tear). Forty adults aged 20-50 with this tear were randomly assigned to one of two arthroscopic repair methods. The goal was to see which surgery better restores kne…

This study looked at 40 children with Hirschsprung disease who had one of two types of surgery to remove the diseased part of the colon and reconnect the healthy part to the anus. The goal was to see which technique led to better bowel function, like the ability to hold in stool …

This study looked at 80 children with a type of hypospadias (a birth defect where the urine opening is not at the tip of the penis) who had a narrow urethral plate. The researchers compared two different surgical repair methods to see which had fewer complications and better cosm…

This study tested a new breathing support method (HVNI) against standard non-invasive ventilation (NIV) in 66 COPD patients with dangerously high carbon dioxide levels. The goal was to see if HVNI could safely lower carbon dioxide and reduce the need for a breathing tube. Results…

This study tested two different tools (a special bur and a magnetic mallet) to widen a narrow jawbone so dental implants could be placed. Five adults with thin jawbones took part. The main goal was to see how stable the implant was right after placement. The study is complete, bu…

This study tested whether a selenium gel can help treat oral lichen planus, a chronic condition that causes painful sores in the mouth. Fifty adults with the condition used either selenium gel, a standard steroid cream, or an immunosuppressant cream. The goal was to see if seleni…

This study tested two different attachment systems (Equator and Novaloc) for lower dentures held in place by dental implants. The goal was to see which one helps dentures stay in place better and improves quality of life for people with no teeth. 26 adults aged 60-70 took part. T…

This study looked at whether surgery to fix a blocked nose can improve snoring and sleep apnea in adults. Thirty people with nasal obstruction and sleep apnea had surgery. The main goal was to see if their breathing pauses during sleep (measured by the apnea-hypopnea index) got b…

This study looked at 100 adults with COPD who needed a breathing tube and a ventilator. It compared two approaches: giving sedation with daily breaks versus giving no sedation at all. The goal was to see which method leads to more days off the ventilator and fewer complications i…

This completed study looked at 400 Egyptian adults who had open-heart surgery to see if living in a hot climate (Upper Egypt) versus a moderate climate (Lower Egypt) affected their bleeding after the operation. Researchers measured how much blood was lost in the first 24 hours an…

This study looked at 201 women who had repeat C-sections to find the best time gap between surgeries. Researchers compared intervals from less than 12 months to over 48 months, tracking complications like bleeding, injuries, and blood transfusions. The goal is to help doctors and…

This study tested two methods to prevent lung collapse after upper abdominal surgery: one using a breathing machine setting (PEEP) and the other adding a lung-opening maneuver. Doctors used ultrasound to check how well the lungs stayed open in 60 adults. The goal was to see which…
