| Toxic epidermal necrolysis(TEN) is a bullous disorder affecting mainly basal layers of epidermis by hypersensitive reaction. It is rarely reported in infants under six months of age. It can be developed by drug, infection, and vaccination, which makes it difficult to differentiate from staphylococcal scalded skin syndrome(SSSS) especially in early infancy. We report a case of TEN in a 6-week-old... |
| Parry-Romberg syndrome(Progressive hemifacial atrophy), described in the last century by Parry(1825) and Romberg(1846), is a very rare disorder characterized by a slowly progressive and self-limited unilateral(rarely bilateral) atrophy of the faces affecting variably the skin, subcutaneous fat tissues, musculature, connective tissue, cartilage and bones. And this disorder is usually accompanied by contralateral Jacksonian epilepsy, trigerminal neuralgia, and changes in the... |
| Marfan syndrome is infrequently diagnosed early in infancy. The morphologic characteristics and prognosis in infantile Marfan syndrome may be quite different from those in older patients. Characteristic cardiac findings in early life include mitral valve prolapse, valvular regurgitation, and aortic root dilation. Morbidity and mortality may be high for infants diagnosed with Marfan syndrome. Cardiac surgery for cardiovascular complication in... |
