A 72-year-old man who suddenly felt an excessive thirst and developed pollakisuria and high fever on Sept. 29, 2001. A general practitioner initially diagnosed him as having urinary tract infection on the same day. Vomiting and unconscionsnes occurred on Oct. 3. He was brought to our hospital by ambulance. Laboratory data on admission showed plasma glucose of 1110 mg/dl, blood pH of 7.167 and HCO3- of 7.6mmol/L, and positive urinary ketone bodies, compatible with diabetic ketoacidosis. Serum amylase was elevated, but he had no symptoms of acute pancreatitis. Insulin therapy was started immediately and hyperglyvemia was improved. He has never had diabetes mellitus and his HbA1c was normal (5.3%). His urinary C-peptide was very low (2.4 μg/day) and diabetes-related autoantibodies including anti-GAD, IA-2 antibodies and ICA were negative. So his case was diagnosed as fulminant type 1 diabetes mellitus. Fulminant type 1 diabetes, which has been brought to light by Dr Imagawa’s group, is characterized by near-nomal HbA1c despite diabetic ketoacidosis, rapid loss of insulin secretion and absence of diabetes-related autoantibodies.Great care is needed to recognize the patients with fulminant type 1 diabetes among the elderly with symptoms of urinary tract infection. Here, we reported the case of an aged man who developed aypical fulminant type 1 diabetes.

Purpose:
Our aim was the longitudinal assessment of cyst size in fetuses with biliary cystic malformation (BCM) to explore its etiology and the possibility of antenatal differentiation between biliary atresia (BA) and congenital biliary dilatation (CBD).
Methods:
We conducted a retrospective review of all patients diagnosed antenatally with BCM from 1994 to 2014 at our institutions.
Results:
The study cohort comprised of three patients with BA and six with CBD. There were no significant differences in the gestational age and cyst size at the first detection of BCM between the two groups. In fetuses with CBD, the cyst size steadily increased as the gestational age advanced, while it fluctuated around 1.5 cm and remained below 2.1 cm in those with BA. However, the ratio of cystic area to fetal trunk area was approximately constant due to linear fetal growth in fetuses with CBD.
Conclusion
Fetuses with BCM <2.1 cm in the late gestation period were more likely to have BA than CBD. Our observation of cyst enlargement with advancing gestational age in the CBD group was attributed solely to fetal growth. Biliary dilatation in fetuses with CBD and BA might be completed at the onset of BCM.

We have previously reported that the thoracolumbar posterior nerve root shows a tortuous epidural course, based on studies of human fetuses near term. For comparison with the cervical nerve, examinations were conducted using frontal, sagittal and horizontal sections of cervical vertebrae from 22 fetuses at 30–38 weeks of gestation. The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity. Fasciculation of rootlets was evident near the thoracolumbar spinal cord, whereas it was seen in the dural pocket at the nerve exit from the dural sac although both sites were subdural. As in the thoracolumbar region, the nerve sheath was continuous with the dura mater and independently surrounded each of the anterior and posterior roots. Radicular arteries were few in the cervical region. In 2 of the 22 fetuses (31 weeks and 33 weeks), there was a segmental, unilateral abnormality of nerve rootlet fasciculation where the dorsal root ganglion was located lateral or peripheral to the intervertebral region. Long nerve roots running inferiorly are a necessary adaptation to the delayed and marked growth of the thoracolumbar vertebral column.In children, the cervical nerve roots are likely to be affected by movement or dislocation of the vertebrae. The segmental abnormality of the cervical nerve root may be linked to rare variations in the brachial plexus.

BACKGROUND/AIMS: Small intestinal bacterial overgrowth (SIBO) is considered to be involved in the pathogenesis of functional gastrointestinal disorders (FGID). However, the prevalence and clinical conditions of SIBO in patients with FGID remain to be fully elucidated. Here, we examined the frequency of SIBO in patients with refractory FGID. METHODS: We prospectively enrolled patients with refractory FGID based on Rome III criteria. A glucose hydrogen breath test (GHBT) was performed using a gas analyzer after an overnight fast, with breath hydrogen concentration measured at baseline and every 15 minutes after administration of glucose for a total of 3 hours. A peak hydrogen value > or = 10 ppm above the basal value between 60 and 120 minutes after administration of glucose was diagnosed as SIBO. RESULTS: A total of 38 FGID patients, including 11 with functional dyspepsia (FD), 10 with irritable bowel syndrome (IBS), and 17 with overlapping with FD and IBS, were enrolled. Of those, 2 (5.3%) were diagnosed with SIBO (one patient diagnosed with FD; the other with overlapping FD and IBS). Their symptoms were clearly improved and breath hydrogen levels decreased to normal following levofloxacin administration for 7 days. CONCLUSIONS: Two patients initially diagnosed with FD and IBS were also diagnosed with SIBO as assessed by GHBT. Although the frequency of SIBO is low among patients with FGID, it may be important to be aware of SIBO as differential diagnosis when examining patients with refractory gastrointestinal symptoms, especially bloating, as a part of routine clinical care.
