background: currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. the purpose of this study was to evaluate the value of serological parameters including serum pepsinogen i (pgi), pepsinogen ii (pgii) and pepsinogen i: ii ratio for the screening atrophic gastritis and gastric cancer.   methods : the study population consisted of 132 dyspeptic patients ...

Hypertrophic and keloid scars are the result of unknown abnormalities in the wound healing process. The aim of this study was to develop physiologically relevant, human in vitro abnormal scar models for hypertrophic and keloid scars and compare these to normotrophic scars and normal skin to identify dierences in the pathogenesis of different scars. Keratinocytes and broblasts from normal skin a...

BACKGROUND Hemangiomas are the most common type of congenital anomaly in childhood. Although many resolve spontaneously, intervention is required when their growth could damage vital adjacent structures. Various therapeutic approaches to childhood hemangiomas with different types of laser have been described previously. The objective of this study was to determine whether the cooling of the epi...

Carbon dioxide (CO2) laser skin resurfacing has been a mainstay of facial rejuvenation since its introduction in the mid 1990s. Recently, a new generation of fractional or microablative CO2 lasers has been introduced to the marketplace. According to the concept of fractional photothermolysis, these lasers ablate only a fraction of the epidermal and dermal architecture in the treatment area. An ...

We report two cases of unilateral gustatory flushing presenting in infancy. This is considered to be a variant of Frey’s syndrome, whereby in children, aberrant sweating is often absent. It occurs as a result of damage, either following perinatal birth trauma or infection. Misdirected regeneration of the parasympathetic fibres of the auriculotemporal nerve results in localised erythema occurrin...
