Background: Studies did not recommend which position for implant overdenture poses the lowest biomechanical risk and the least chance of peri-implant bone loss and ridge resorption for those who might need a mandibular two-implant overdenture. The study objectives were to investigate the impact of implant position, in lateral incisors or canine positions, on peri-implant bone loss and posterior ridge resorption.

Methods: Fifty patients with mandibular two-implants were recalled and divided according to the implant position into two groups (group L: implants in lateral incisor positions and group C: implants in canine positions).

Background: There is insufficient evidence recommending a framework material and a CAD/CAM manufacturing technique for mandibular implant-supported prostheses. The study objective was to evaluate the clinical application of different materials and construction techniques used for mandibular All-on-4 prosthesis on circumferential peri-implant bony changes after 5 years.

Methods: Thirty-six male patients with all-on-4 mandibular implant-supported prostheses were recalled and divided into three groups.

Purpose: This study was conducted to evaluate the clinical peri-implant soft tissue changes during the first year after occlusal loading and the ridge base relation after 3 years for mandibular computer-aided design and computer-aided manufacturing (CAD-CAM) screw-retained implant-supported hybrid prosthesis of polyetheretherketone (PEEK) framework utilized with All-on-Four treatment concept.

Materials And Methods: Sixteen completely edentulous patients were rehabilitated by four implants following the All-on-Four protocol. After 3 months, the definitive prosthesis was constructed to be a screw-retained CAD-CAM milled framework from the modified PEEK (BioHPP), bonded to polymethylmethacrylate teeth and a pink shaded indirect light-polymerized nanofilled composite resin imitating the soft tissues.

Background: Despite the good outcomes achieved with intravitreal angiogenic therapy, a subset of neovascular age-related macular degeneration (AMD) patients experience resistance to therapy after repeated injections. Switching drugs could offer benefit to this group of patients.

Purpose: To determine visual and anatomical outcomes in a cohort of neovascular AMD patients resistant to repeated injections of bevacizumab/ranibizumab after switching to aflibercept therapy.

Background: Epiretinal membranes (ERMs) have been reported after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). Peeling of the internal limiting membrane (ILM) can prevent post-PPV ERM formation but has a potential negative impact on macular structure and function.

Purpose: To investigate the anatomical and functional outcomes of ILM peeling during PPV for primary RRD.

The use of Alcohol-based antiseptics is efficient and approved, however it has some limitations. This paper examined the possibility of using hypochlorite water as a chlorine-based antiseptic for handwashing in public buildings and healthcare facilities. The electrolysis method was used, which produces Hypochlorous acid (HOCl) from mixing drinking water with small amounts of sodium hydroxide.

Water-, sanitation-, and hygiene-related diseases are killing many people each year in developing countries, including Rwanda, and children under the age of five are the most vulnerable. This research assessed human waste disposal practices, knowledge on diseases caused by contact with human faeces, and knowledge on causes and prevention of selected WASH-related diseases. One thousand one hundred and seventy-three students were interviewed out of 2900 students.

Background: A growing interest had been paid to goal-directed fluid therapy (GDT) in abdominal surgery; however, its impact on the respiratory profile was not well investigated.

Aim: We evaluated the impact of GDT on postoperative extravascular lung water and oxygenation after prolonged major abdominal surgery.

Methods: A randomised, controlled study was conducted in Kasr Alainy hospital from April 2016 till December 2017 including 120 adult patients scheduled for prolonged major abdominal surgery.

Background: Pain is a major postoperative complication worldwide, which in turn impairs normal body performance and increases postoperative morbidity, hospitalisation, and the susceptibility to infections which also lead to chronic pain development.

Aim: The purpose of this study was to evaluate the efficacy of intravenous ketorolac versus nalbuphine as analgesia after adenotonsillectomy surgery to determine the optimal procedure for pain control and postoperative reduction of analgesic use.

Methods: A group of 100 pediatric patients undergoing tonsillectomy or adenotonsillectomy were assigned as follows to two equal groups: Group A: 50 patients received intravenous ketorolac 0.

This study examined an econometric analysis of the macroeconomic determinants of carbon dioxide (CO) emission in Nigeria, covering the periods between 1981 and 2016, employing both linear and non-linear Autoregressive Distributed Lag (ARDL & NARDL) models. The time series data used were sourced from the database of the World Bank Development Indicators, 2016 and Central Bank of Nigeria Statistical Bulletin, 2017 edition. The main macroeconomic variables driving CO emissions in Nigeria were considered.

Many people around the globe prefer bottled water especially in developing countries, where tap water is not drinkable. This study investigated the quality of bottled drinking water sold in Lilongwe city, Malawi. Compliance with Malawi Standards (MS) 560 (2004) for natural mineral water, MS 699 (2004) for bottled water and the World Health Organisation guidelines for drinking water were examined.

The potential energy curves of the 19 lowest-lying singlet and triplet electronic states in the (2S+1)Λ((+/-)) representation of the AsCl molecule have been investigated using the complete active space self-consistent field (CASSCF) with multireference configuration interaction (MRCI+Q) method including single and double excitations and with the Davidson correction. The harmonic frequency ω e, the internuclear distance R e, the dipole moment, and the electronic energy with respect to the ground state T e were calculated for the electronic states considered. By using the canonical functions approach, the eigenvalue E v, the rotational constant B v, and the abscissae of the turning points R min and R max were calculated for the electronic states up to the vibrational level v = 60.

Jejunogastric intussusception is a rare complication after gastric surgery. The authors report a case of acute jejunogastric intussusception diagnosed in a 57-year-old woman, 22 years after vagotomy and gastroenterostomy for duodenal ulcer. There are three types of jejunogastric intussusception: 1) the acute type, presenting as a surgical emergency, and characterized by a sudden onset of cramp-like epigastric pain, followed by nausea and vomiting, with a palpable epigastric mass.

We report 18 cases of pain and tenderness in the mid-part of the patellar ligament in athletes. The condition may be disabling, but it responds to surgery. Ultrasound and CT scans were positive in all 17 confirmed cases, but ultrasound gave a better distinction between the cysts, granulation tissue, metaplasia, mucoid degeneration and congenital defects found at operation.
