OBJECTIVE To describe the eruption chronology of the first deciduous teeth in premature infants with birth weight less than 1500 g and to compare it according to gender and nutritional status at birth. METHODS Longitudinal study including 40 low birth weight premature infants of both genders. The tooth was considered erupted when the crown went through the gum and became part of the oral envi...

OBJECTIVE To evaluate the relationship between the stages of dental formation and the timing of eruption of mandibular second premolars. MATERIALS AND METHODS The sample comprised panoramic radiographs of 25 children, 7 to 12 years old, observed by space supervision during development of dentition. The initial radiograph (T1) was taken in the mixed dentition period and the progress radiograph...

Eruption sequestrum is an uncommon disturbance in eruption and consists of small fragments of calcified tissue overlying the crowns of erupting permanent molar teeth, especially at the time of eruption of the mandibular first molars. This paper reports a case of unilateral eruption sequestrum in a 7-year-old Brazilian boy and describes its histopathological findings. A white small fragment, 0.5...

Ectopic eruption is the abnormal eruption of a permanent tooth that often causes root resorption of an adjacent primary tooth which can be noted during routine dental radiographic evaluation. The mesial eruption of the permanent first molar may be a local eruption problem or may indicate developmental arch circumference deficiency requiring further consideration. Early treatment is mandatory to...

In this paper, we present some physical models that can describe the ascent of volcanic ash into the atmosphere during a volcanic eruption. We consider both sustained volcanic eruption columns and discrete volcanic thermal clouds. To test the modeling approach, we compare our predictions of the ascent rate of a model cloud with some observations of the ascent of the ash cloud during the April 1...

Pruritic urticarial papules and plaques of pregnancy (PUPPP)(also known as polymorphic eruption of pregnancy in Europe) is an intensely pruritic eruption that affects women during the third trimester of pregnancy. Treatment usually is aimed at symptom relief until delivery, as the eruption usually resolves rapidly in the postpartum period. We report the case of a 30-year-old woman who presented...

Kaposi's varicelliform eruption (eczema herpeticum) is the name given to a distinct cutaneous eruption caused by herpes simplex and certain other viruses that infect persons with preexisting dermatosis. Most commonly it is associated with atopic dermatitis. We report a case of a three-year-old atopic child who presented with extensive vesicular eruption suggestive of Kaposi's varicelliform erup...

the patient is a 69 years old female presented with chest pain and rapidly progressive dysphagia. then she suffered of hematemesis and aphagia. in evaluation of patient, a intramural hematoma obstructing esophageal lumen was demonstrated which was accompanied with mucosal ulceration and bleeding. it appears that this complication occurred in the context of concomitant use of alendronate with as...

anticoagulation drugs are frequently used to prevent deep vein thrombosis in high-risk patients. subcutaneous low molecular weight heparin (lmwh) is increasingly used in both hospitalized patients and outpatient settings. this necessitates familiarity of both health care providers and patients with such treatment and vigilance on possible complications. here we present a case of hematoma of rec...
