Normal growth is a sign of good health. Monitoring for growth disturbances is fundamental to children's health care. Early detection and diagnosis of the causes of short stature allows management of underlying medical conditions, optimizing attainment of good health and normal adult height.
Conclusion
This review summarizes currently available information on monitoring for short stature in children and conditions usually associated with short stature and summarizes the authors’ conclusions on the early recognition of growth disorders. 相似文献92.
Microglandular adenosis (MGA) and atypical MGA (AMGA) are unusual lesions of the breast. They were once regarded as benign proliferative lesions and innocent bystanders. Several lines of evidence suggested that they could be neoplastic, clonal lesions and a non‐obligate precursor for triple‐negative breast cancers (TNBC). Recent work published in The Journal of Pathology by Guerini‐Rocco and colleagues provided further evidence regarding the precursor–product relationship between MGA/AMGA and TNBC. Using a massively parallel sequencing approach, they demonstrated that MGA/AMGA, particularly those associated with TNBC, could be clonal neoplastic lesions showing clonal non‐synonymous mutations, but none in pure MGA. Importantly, those alterations were observed in the associated TNBC. They were also able to identify recurrent alterations in TP53 in those MGA/AMGA cases as well as their associated TNBC. The findings, in conjunction with others, underscore the significance for MGA in clinical diagnosis. The potential of a benign lesion to progress into an aggressive malignant tumour implies that modification of the current management approach may be necessary.

Background
The relationship between bone mineral density (BMD) and type 2 diabetes mellitus (T2DM) has been controversial. Recent studies have revealed adverse impact of antidiabetic drugs on BMD in type 2 diabetic patients. However, the influence of various antihyperglycaemic agents on BMD has not been well studied.Method
A total of 200 patients with T2DM were screened initially for the study. Finally 67 patients (M:34, F:33) who satisfied the requirement of having been on one year of prescribed therapy were included for analysis.Results
Bone mineral density was lower in diabetic patients as compared to controls (hip 0.962 ± 0.167 g/cm2 vs 1.013 ± 0.184 g/cm2, P = 0.05; spine 0.929 ± 0.214 g/cm2 vs 1.113 ± 0.186 g/cm2, P < 0.00001). In males BMD was significantly lower at spine (P < 0.00001) and in females BMD was significantly lower in both at the spine (P < 0.00001) and hip (P < 0.032). On multivariate analysis significant positive correlation was found between spine BMD and body mass index (BMI) (r = 0.372, P = 0.002), total cholesterol (r = 0.272, P = 0.026), low-density lipoprotein (r = 0.242, P = 0.047), and triglycerides (r = 0.282, P = 0.021). There was no correlation between BMD and glycosylated haemoglobin (r = 0.158, P = 0.265). A significant decrease in BMD at spine and hip was seen with the use of glitazones and metformin while increase was noted with sulphonylurea and its combination.Conclusion
Men and women with T2DM have lower BMD. Bone mineral density did not have correlation to glycaemic control. Glitazones, metformin, and insulin are associated with decrease in BMD at spine, and hip, while sulphonylureas are associated with increase in BMD.Key Words: antihyperglycaemic drugs, bone mineral density, type 2 diabetes mellitus 相似文献95.

A case of two secondary aneurysmal bone cysts arising in fibrous dysplasia during pregnancy is reported. Marked radiographic changes were seen in one lesion over a 3-week period. The development of these cysts during pregnancy strongly suggests that the hemodynamic and/or hormonal changes of pregnancy were responsible for their formation. 相似文献
