Resting energy expenditure in short-stature children

It is not clear what dietary intake standards should be used for children with abnormal body size. To investigate the energy requirements of short-stature children with no underlying diseases, their resting energy requirements (REE) were measured by indirect calorimetry. The short-stature group consisted of 30 prepubertal children with short stature and with no underlying diseases (age 6y±2) and the control group consisted of 13 age-matched children with standard stature. Fasting REE and the respiration quotient (RQ) with subjects in the supine position were measured by canopy indirect calorimetry. Actual measurements and body-size-adjusted REEs were compared between the groups. Also, REE measurements were compared with the basal metabolic rate (BMR) calculated using the Dietary Reference Intakes for Japanese (Dietary Reference Intakes). REE in the control group was significantly higher than that in the short-stature group. However, body-size-adjusted REEs were significantly higher for the short-stature group. When the actual REE was compared with the calculated BMR within both the control group and the short-stature group, which was acquired using the Dietary Reference Intakes, there was no difference within the control group but the actual REE measurements were significantly higher than the calculated BMR in the short-stature group. The same pattern was seen within the short-stature group when subjects were matched for height. There were no significant differences in RQ between the two groups.     

Three cases of pneumatosis intestinalis presenting in autoimmune diseases

Pneumatosis intestinalis (PI) is a comparatively rare disease characterized by the presence of intramural gas in the gastrointestinal tract. PI is known to be associated with several clinical conditions, such as pulmonary diseases, gastrointestinal diseases, and traumatic injury, as well as autoimmune disorders. In particular, PI is commonly seen in systemic sclerosis (SSc) but rarely in systemic lupus erythematosus and dermatomyositis (DM). In this report, we present three cases of PI presenting in autoimmune diseases, including DM, Sj?gren's syndrome, and limited SSc, and further discuss its background characteristics.

Nutritional risk index as an independent predictive factor for the development of surgical site infection after pancreaticoduodenectomy

Purpose

Malnutrition has been considered a risk factor for the development of a surgical site infection (SSI). The aim of this study was to determine the relationship between preoperative nutritional screening scores and the development of SSI after pancreaticoduodenectomy.

Methods

We examined 64 patients who had undergone pancreaticoduodenectomy. Their clinical data, nutritional risk index (NRI), and nutritional risk screening 2002 (NRS-2002) score were recorded. SSIs were diagnosed according to the definitions of wound infection established by the Center for Disease Control and Prevention and were confirmed by a microbiological examination. Data were analyzed using the Fisher exact probability method and a multivariate logistic regression analysis.

Results

SSIs developed in 21 patients (33 %). Eleven patients had wound infections, and 14 patients had an intra-abdominal abscess. A univariate analysis of perioperative factors revealed that a pancreatic fistula, the NRS-2002, and the NRI were significantly associated with the development of SSI (p < 0.05). The multivariate logistic regression analysis revealed that a pancreatic fistula and the NRI were independent risk factors for SSI. By analyzing the pre- and intra-operative factors after excluding the 11 patients with pancreatic fistulas, the NRI was still an independent risk factor for SSI.

Conclusion

The present study showed the NRI to be an independent factor for predicting the risk of SSI after pancreaticoduodenectomy.     

Acute limbic encephalitis with focal hyperperfusion on single photon emission computed tomography

Here we report an 11-year-old boy with acute encephalopathy with neuropsychiatric symptoms. The patient had mildly decreased consciousness, delirious behavior, and affective changes next day of fever onset. Hematologic, biochemical, and metabolic examinations were unremarkable. CSF analysis revealed cell counts of 278 cells/mm³ and a protein level of 87 mg/dL. Although MRI revealed no abnormal findings, an increase in regional cerebral blood flow was present in the bilateral frontal lobes, mesial temporal lobes, and basal ganglia on single photon emission computed tomography. The measurement of the concentrations of biomarkers such as cytokines in the patient’s serum and cerebrospinal fluid revealed elevated levels of IL-4 and TNF-α in the cerebrospinal fluid. Immunohistochemical studies applying control human brain sections did not demonstrate the presence of autoantibodies. We considered that innate immunity rather than autoantibody response may have contributed to the neuropsychiatric symptoms of our patient. These results suggest heterogeneity of patients with acute encephalopathy with neuropsychiatric symptoms.
