Radiologically diagnosed rickets was found to be common in children of the poorer classes in Tehran. It was frequently associated with gastroenteritis or bronchopneumonia and a large proportion of the children were severely underweight for their age. In children below the age of 1 year malnutrition tended to mask the signs of rickets. Convulsions were much less frequent in the malnourished children; the concentration of calcium in the serum was higher and that of alkaline phosphatase was lower than in those who were well nourished. Biochemistry is of little value in the diagnosis of rickets in the presence of malnutrition.
经放射学诊断的佝偻病在德黑兰贫困阶层儿童中很常见。它常与肠胃炎或支气管肺炎相关,而且很大一部分儿童年龄别体重严重偏低。1岁以下儿童的营养不良往往会掩盖佝偻病的体征。营养不良儿童惊厥的发生频率要低得多;其血清钙浓度较高,碱性磷酸酶浓度低于营养良好的儿童。在存在营养不良的情况下,生化检查对佝偻病的诊断价值不大。
