We conclude that the detrimental effect of low prepregnancy BMI in Japanese women on birthweight and incidence of SGA infants. Our findings suggest that appropriate maternal BMI at conception followed by adequate weight gain during pregnancy may have a substantial influence on reducing the SGA infants and increasing the birthweight.

Multiple logistic regression analysis revealed a reduced incidence of depression in women whose intake of folate exceeded the RDA of 240 μg per day. This finding suggests that dietary folate intake may be causally related to depressive symptoms in women of reproductive age. If results of studies powered to determine causal relationships are similarly positive, folate supplementation could reduce the incidence of depression.

A 79-year-old woman complaining of epigastric pain was examined by her local physician, who found an abdominal mass and referred the patient to our department. Abdominal plain computed tomography revealed a mass, 50 mm in size, with slight calcification on the ventral side of the head of the pancreas. On abdominal ultrasound, the mass lesion consisted of an aggregation of hypoechoic masses, with a heterogeneous hyperechoic region at its center. On contrast ultrasonography, only the hyperechoic region was stained. (18)F-Fluorodeoxyglucose-positron emission tomography (FDG-PET) revealed FDG accumulation in the same region. It was difficult to differentiate between a malignant pancreatic tumor and an inflammatory disease on imaging, but since QuantiFERON TB2G testing was positive, pancreatic tuberculosis was suspected, and endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) was performed to obtain a definitive diagnosis. Samples from the hypoechoic region consisted of necrotic tissue, while those from the hyperechoic region consisted of pancreatic tissue together with granulation tissue. BCG immunostaining was positive, and a diagnosis of pancreatic tuberculosis was made. If EUS-FNA is performed on stained areas seen on contrast ultrasonography, this will probably enable a more accurate diagnosis of pancreatic tuberculosis with low invasiveness.
