No previous studies have focused on postoperative fat malabsorption in children with choledochal cyst (CC) who undergo cyst
excision and Roux-en-Y (RY) hepatico–jejunostomy (HJ), a combination of procedures that can lead to the non-physiological
mixture of food and bile juice. To examine the effect of RYHJ with cholecystectomy on the fat absorption ability of children
with CC, we estimated postoperative fat-absorption ability using the carbon 13-labeled mixed triglyceride (13C-MTG) breath test. Twelve postoperative children with CC and 12 normal control children were administered 13C-MTG orally and asked to give breath samples at six time points: once before the 13C-MTG ingestion and at five 60-min intervals post-ingestion. Fecal chymotrypsin activity and fecal fat excretion were also
measured. The delta value of breath 13CO2 at 3, 4, and 5 h after administration and the 5-h cumulative breath 13CO2 were significantly lower in the CC children than in the controls. There were no significant differences in the fecal chymotrypsin
activity or fecal fat excretion of the two groups. Conclusion. Occult fat malabsorption occurs in patients with CC after RYHJ, even in the absence of clinical symptoms or abnormal laboratory
data. 相似文献

Gastroenteric duplication rarely occurs in locations such as the pancreas. We report a case of gastroenteric duplication of the pancreatic tail, which was noncontiguous with the stomach and had no communication with the pancreatic duct, in a 3-year-old girl. The cyst was enucleated by laparoscopy, without the need for pancreatic resection. The optimal treatment procedures vary considerably, depending on where the gastroenteric duplication is located in the pancreas and, most importantly, whether there is communication with the pancreatic duct. 相似文献

To thoroughly understand the role of IL-4 in the pathogenesis of systemic lupus erythematosus (SLE), a prototypic antibody-mediated systemic autoimmune disease, we examined the potential of in vitro IL-4 production by anti-CD3 mAb-stimulated splenic T cells in SLE model of NZB, BXSB and related mouse strains. Unexpectedly, both SLE-prone NZB and BXSB mice had a limited potential to produce IL-4, while disease-free NZW mice had a high potential. Levels in (NZB x NZW) F1 and (NZW x BXSB) F1 were in between. Genome-wide search for quantitative trait loci (QTL) controlling this variation identified a single significant QTL in the vicinity of IL-4Ralpha gene on chromosome 7. Sequence analysis of IL-4Ralpha cDNA revealed that there are 17 nucleotide substitutions resulting in eight amino acid changes between NZB and NZW strains. BXSB showed the identical sequence, as did NZB. Thus, it was suggested that the NZW-type polymorphism controls a high potential and the NZB/BXSB-type polymorphism controls a low potential for IL-4 production by T cells. Linkage studies using NZW x (NZW x BXSB) F1 male and (NZB x NZW) F1 x NZW female back-cross mice revealed that the BXSB/NZB-type IL-4Ralpha polymorphism significantly linked to BXSB, but not to (NZB x NZW) F1 lupus. Thus, the low IL-4-producing phenotype appears to predispose to SLE in BXSB, but not NZB-related strains, suggesting that the role of IL-4 in the pathogenesis may differ between certain subsets of SLE, even if they show similar disease phenotypes. 相似文献

The intrauterine environment affects the development of insulin resistance in adulthood. To determine the influence of foetal growth restriction on glucose metabolism, we assessed indices of insulin sensitivity soon after birth in very premature infants. Blood samples were collected at birth from 52 premature infants with a gestational age of ≤31 weeks, who were divided into a group whose birth weight was small for their gestational age (SGA group, n=19) and a group whose birth weight was appropriate for their gestational age (AGA group, n=33). Blood glucose, serum insulin and C-peptide immunoreactivity (CPR) levels were measured in both groups. Furthermore, the quantitative insulin check index (QUICKI) was also calculated. Correlations between these indices and glucose metabolism and the standard deviation (SD) score for birth weight were also determined. The levels of insulin and CPR were significantly (p<0.05) lower in the SGA group than in the AGA group. The QUICKI was significantly (p<0.05) higher in the SGA group compared with the AGA group. The SD score for birth weight was correlated with the QUICKI (p<0.01), the serum insulin level (p<0.05) and the CPR level (p<0.05) in all 52 infants. Conclusion: In very premature infants, poor foetal growth may impair foetal insulin secretion and affect the QUICKI at birth. 相似文献

We report a familial case with a proximal interstitial deletion of chromosome 21q [del(21q)]. Although the mother in the family was phenotypically normal, her first child was affected with both sensorineural hearing loss and moderate mental retardation, and the second affected child had mild mental retardation but not sensorineural hearing loss. We determined breakpoints of the del(21q) in the mother and her two affected children by fluorescence in situ hybridization analysis using 45 DNA clones and the molecular analysis using 21 DNA markers. The proximal breakpoint of the del(21q) was located at a region between 0.33 Mb and 0.46 Mb distal to the centromere, and the distal breakpoint was at a region between 14.6 Mb and 14.9 Mb. The finding indicates that the three individuals had an approximate 14-Mb deletion within 21q11.2-q21.3. Molecular analysis showed that both affected children shared the same maternal haplotype of their del(21q), but a crossover was detected in the paternally inherited normal chromosome 21. These data suggest that unmasking of deleterious genes on the paternally derived chromosome 21 of the two children as a result of the deletion may affect the extent of their mental retardation and/or sensorineural hearing loss. Usher syndrome 1E may be a candidate disease locus related to the sensorineural hearing loss of the first child. 相似文献

PROBLEM: The presence of antisperm antibodies (ASA) in males can reduce fecundity, however, relationship between the two is disputed. This study was performed to investigate if there is diversity of ASA bound to sperm surface using immunobead test (IBT) combined with complement dependent sperm immobilization test (SIT). METHODS: The ASA bound to sperm surface were detected using the direct IBT (D-IBT) in 275 semen samples. In some cases with ASA detected by D-IBT, sperm immobilizing antibodies bound to sperm surface were also evaluated using direct SIT (D-SIT). RESULTS: The incidence of the immunoglobulin G (IgG), IgA, and IgM classes of ASA detected by D-IBT were 2.5, 1.8, and 0.4%, respectively. Totally, nine (3.3%) infertile men had ASA on the sperm surface. D-SIT was tested positive in four (66.7%) of six cases with ASA assessed by D-IBT. CONCLUSIONS: Some of the sperm-bound antibodies are associated with complement dependent sperm immobilizing antibodies, indicating that there exists a heterogeneity of sperm-bound antibodies. This result might be one of the reasons for the controversy about the relationship between ASA and immunological infertility in men. 相似文献

X-linked agammaglobulinemia (XLA) is clinically characterized by recurrent bacterial infections during early infancy. Although it is not a phagocytic disorder, XLA is sometimes associated with neutropenia. We conducted a nation-wide survey to determine the frequency of neutropenia among Japanese XLA patients. Responses were received from 87 (86%) of 101 patients in which BTK mutations were previously identified, and of these, 16 (18%) had neutropenia. All episodes of neutropenia occurred before initiation of intravenous immunoglobulin (IVIG) replacement therapy. Two XLA patients died of multiple organ failure caused by severe neutropenia and Pseudomonas sepsis before initiation of IVIG replacement therapy. These results suggest that, in some cases, severe bacterial infections in XLA patients might be caused not only by antibody deficiencies but also by neutropenia. 相似文献
