ABSTRACT
Introduction: The pathway of glycogen metabolism is regulated by many hormones such as insulin, glucagon, and corticosteroids. Glycogen storage diseases [GSD] most commonly affect muscles, liver, or both and occur in each 20000 to 43000 live birth. They are classified into 12 subtypes, but types I, II, and IX are the most common
Methodology: We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, from January 2001, through February 2017. The following search terms were used: glycogen storage diseases, Von Gierke disease, Pompe's disease, Cori Disease, Forbes disease, Andersen's disease, McArdle disease, neonatal hypoglycemia, neonatal hepatomegaly
Aim: In this review, we aim to study the genetic basis, diagnosis, presentation, and different management approach to various common types of glycogen storage diseases prevalent in pediatric population
Conclusion: There are no cures for any type of glycogen storage diseases presently. Most treatments are designed to control signs and symptoms. The overall goals are primarily avoiding hypoglycemia, hyperlactatemia, hyperuricemia, and hyperlipidemia. Liver transplantation should be deliberated for patients with GSD type IV and for other progressive hepatic types of GSDs in order to avoid hepatic failure or malignancy. More research must be carried out to develop newer and more effective ways of management
ABSTRACT
Background: Upper gastrointestinal bleeding is the most common gastrointestinal cause of admission in emergency departments worldwide with about 10% inpatient mortality rate that has not decreased during the last three decades
Aim: In this review, we aim to study the pathophysiology behind the development of upper gastrointestinal bleeding, and explore the approach to its management in emergency situation
Materials and Methods: We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, January 2001, through February 2017. The following search terms were used: upper gastro intestinal bleeding, variceal bleeding, emergency management of gastrointestinal hemorrhage, varices, esophageal bleeding
Results: Managing patients with bleeding varices must have two goals that should be considered: to stop the bleeding, and to prevent rebleeding since 60% of patients will rebleed after the acute bleeding was stopped leading to a mortality rate of 33%, unless adequately treated
Conclusion: Bleeding varices are always considered urgent emergencies due to associated morbidity and mortality. Moreover, bleeding varices can cause hemodynamic instability and end-organ failure. The most important intervention is therapeutic endoscopy. Other approaches include vasoactive drugs, and prophylactic antibiotics. After acute management of the bleeding, patients should undergo further evaluation and treatment to prevent the recurrence of another bleeding
ABSTRACT
Aim of the work: the contact lenses are widely used for management of refractive errors and cosmetic purposes as well. Their complications are rare and usually caused by in appropriate maintenance of the lens and bad habits for wearing too long
Methodology: all the English data related to the subjects were collected after reviewing Pubmed, SCOPUS, Science Direct and other search engines
Results: this review showed the most common complications, risk factors and management of diseases related to contact lens wearing. Each problem was described by its symptoms, risk factors and management as well as prognosis
Conclusion: the selection of proper lens and education about the lens care system is efficient for reducing the complications related to contact lens
ABSTRACT
Background: Nasal polyposis are considered a sign or a physical finding rather than a disease resulting from a complex process that is found in some individuals, such as people suffering from chronic sinusitis, rhinitis, Kartagener's syndrome, or cystic fibrosis. Sinonasal polyps can have four distinct histological subtypes, which include eosinophilic polyp, chronic inflammatory polyp, hyperplastic polyp, and polyp with stromal atypia
Aim: In this review, we aim to study the presentation, classification and diagnosis of nasal polyps in the light of histopathological findings
Materials and methods: We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, January 2001, through February 2017. The following search terms were used: nasal polyp, inflammation of nasal mucosa, chronic inflammation, histology of nasal mucosa, pathology of nasal polyps
Conclusion: Polyposis does not have histological problems and complications. However, they may be clinically disturbing. Polyps are not classified into allergic and non-allergic, and are rather stratified according to histological findings, making histological investigation crucial for diagnosis
