Juvenile xanthogranuloma (JXG) is a benign, self-healing, non-Langerhans cell histiocytosis characterized by accumulation of lipid-laden macrophages. It occurs most commonly on the head and neck of infants and young children and resolves spontaneously without treatment [1]. Lesions may be single or multiple, congenital or acquired.

Biopsy specimens from 14 patients treated for laryngeal papillomatosis were tested for the presence of human papillomavirus (HPV) genome by the technique of DNA-DNA hybridisation. According to the age of initial presentation, cases were subdivided into juvenile (less than 16 years) and adult onset (older than 16 years) groups. Histological investigation confirmed that it was impossible to disti...

Introduction Because most children with oligoarticular juvenile idiopathic arthritis (o-JIA) were mildly affected (Steinblocker functional class I, c.a.85%), o-JIA is tend to be thought of as a mild subtype of JIA. However, 6% of them were unable to participate in a full school program 5 years after diagnosis, and 0.5% of children with o-JIA progressed to class III or IV, severe to terminal sta...

BACKGROUND AND AIMS Tolerance and defence against herbivory are among the many mechanisms attributed to the success of invasive plants in their novel ranges. Because tolerance and defence against herbivory differ with the ontogeny of a plant, the effects of herbivore damage on plant fitness vary with ontogenetic stage and are compounded throughout a plant's lifetime. Environmental stresses such...

The tegumental ultrastructure of juvenile and adult Himasthla alincia (Digenea: Echinostomatidae) was observed by scanning electron microscopy. One-, 5- (juveniles) and 20-day-old worms (adults) were harvested from chicks experimentally fed metacercariae from a bivalve, Mactra veneriformis. The juvenile worms were elongated and curved ventrally. The head crown bore 31 collar spines, arranged in...

BACKGROUND Granulosa cell tumor of the testis is a rare intermediate stromal cell tumor that can be distinguished in the adult and juvenile type. The juvenile type is the most common reason for scrotal swelling in newborns under the age of six months. Less than fifty cases of this disease entity have been reported in the literature. PATIENTS AND METHODS In the following article, two newborn p...

We measured oxygen consumption in juvenile Chinese striped-necked turtles (Ocadia sinensis) after they ingested food, either as a single meal or as double meals, to examine the influence of meal type and feeding frequency on specific dynamic action (SDA). Temporal variation in oxygen consumption after feeding was evident in the ingesting turtles but not in the unfed control turtles. In the sing...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

the purpose of this study was to investigate any association between iga deficiency (igad) and juvenile rheumatoid arthritis (jra) among iranian children. this case-control study was carried out on 83 children who were diagnosed as jra according to american college of rheumatology (acr) criteria; patients were admitted at the rheumatology clinic of children's medical center, (tehran). serum imm...
