Enterohemorrhagic Escherichia coli (EHEC) is an important cause of bloody diarrhea in children, but is considered to be rare in infants. Herein, a case of infant hemorrhagic colitis of verotoxin-producing E. coli O157:H7 diagnosed by multiplex PCR is reported. A nine-month-old boy was admitted to our hospital with bloody diarrhea for the previous two days. Multiplex PCR using Seeplex(R) Diarrhea ACE Detection Kit (Seegene, Seoul, Korea) was directly applied to the stool specimens. Amplified bands specific for verotoxin, O157, and H7 indicated the presence of O157:H7 EHEC. The stool specimens were inoculated on sorbitol-MacConkey agar (SMA) and tryptic soy broth containing mitomycin C (TSB-M). Colorless colonies on sorbitol-MacConkey agar were O157-positive. TSB-M enrichment cultures of the stool specimen and the isolates were positive for verotoxin according to an enzyme immunoassay (EIA). The prepared ingredients of baby foods for the patient including ground meat, chopped carrot, chopped cabbage, and white rice porridge showed no EHEC on TSB-M and SMA. The patient's parents and three-year-old sister did not recently have any gastrointestinal symptoms. Cefdinir was administered for one day and was ceased after diagnosis of EHEC colitis. The stool culture and verotoxin assay were negative on the second day of hospitalization. Application of multiplex PCR and verotoxin EIA directly to diarrheal stool warrants the rapid diagnosis and appropriate treatment of EHEC colitis.

As the duration of diabetes mellitus (DM) increases, the risk of complications increases and the prevalence of depression becomes higher. Most studies on depression in Korean patients with DM have focused on a point 5-10 years after diagnosis, and there has not been much data reported regarding the early stages of DM, including newly developed DM. In this study, we examined whether blood glucose levels could be associated with emotional symptoms such as depression (DS) and anxiety (AS) in patients newly diagnosed with DM. Serum glucose and HbA1c were measured in 89 patients with DM. The Impact of Event Scale (IES) was used to investigate the extent of the psychological impact of a diagnosis of DM. The IES comprises four elements: hyperarousal, intrusiveness, avoidance, and sleep problems. DS and AS were investigated using the Hospital Anxiety and Depression Scales. DS was observed in 32 patients (36%) and AS was observed in 21 patients (23.6%), indicating a higher prevalence of DS and AS than in the general population. There was an inverse correlation between HbA1c and DS (Pearson's correlation coefficient: R = -0.227; P = 0.035), but no correlation was found for AS. The four elements of the IES had significant correlations with DS and AS. Logistic regression analysis showed that sleep problems (OR = 1.437) and HbA1c (OR = 0.51) were associated with DS, but only intrusiveness (OR = 0.629) showed a correlation with AS. In patients newly diagnosed with DM, DS is associated with sleep problems and low HbA1c levels. Emotional symptoms should be considered as part of glucose control, and efforts to mitigate psychological stress during the initial period of diabetes management should be made.
