We report on five cases of mucosal atrophy of the gastric body, under the aspect of a polyposis: These polyps showed intact mucosa with abundant fundic glands and were situated in the diffuse atrophic mucosa of the gastric body. Four of these cases were manifestations of type A gastritis, in one case the lesion surrounded a peptic ulcer. Laboratory findings of serologically analysed cases with type A gastritis showed elevated parietal cell antibodies in all cases, two of three cases showed a high level of gastrin, the values for vitamin B12 showed different levels; no patients revealed antibodies against the intrinsic factor, and no patient had pernicious anemia. The family history revealed three cases with cancer of the stomach on one side of the parents. It is important to biopsy polyps and the flat mucosa separately in order to verify this form of atrophy of the gastric mucosa and to also exclude small polypous tumors of the mucosa. Observation of the number of polyps allows a control of the extent of the atrophy of the mucosa. 相似文献

A stereotaxic technique for localization of occult breast lesions and fine needle aspiration for cytological diagnosis was used on examination of 543 patients. Successful localization with the needle tip within 1 mm of the suspected lesion was possible in 490 patients (90.2%). Based on a high mammographic index of suspicion for malignancy, 187 of 490 patients were selected to undergo open biopsy, following aspiration cytology and localization with methylene blue injection. The statistical results (cytologic vs. histologic examination) revealed a sensitivity of 97.5% and a specificity of 95.2% for cytologic diagnosis of occult breast lesions. The technique is easy to learn and takes 20-30 minutes to perform. Compliance was 100% and complications were nil. This new technique expedites localization and maximizes the specificity of mammography for occult breast lesions. 相似文献

Breastfed infants have higher intestinal lipid absorption and neurodevelopmental outcomes compared to formula-fed infants, which may relate to a different surface layer structure of fat globules in infant formula. This study investigated if dairy-derived emulsifiers increased lipid absorption and neurodevelopment relative to soy lecithin in newborn preterm piglets. Piglets received a formula diet containing soy lecithin (SL) or whey protein concentrate enriched in extracellular vesicles (WPC-A-EV) or phospholipids (WPC-PL) for 19 days. Both WPC-A-EV and WPC-PL emulsions, but not the intact diets, increased in vitro lipolysis compared to SL. The main differences of plasma lipidomics analysis were increased levels of some sphingolipids, and lipid molecules with odd-chain (17:1, 19:1, 19:3) as well as mono- and polyunsaturated fatty acyl chains (16:1, 20:1, 20:3) in the WPC-A-EV and WPC-PL groups and increased 18:2 fatty acyls in the SL group. Indirect monitoring of intestinal triacylglycerol absorption showed no differences between groups. Diffusor tensor imaging measurements of mean diffusivity in the hippocampus were lower for WPC-A-EV and WPC-PL groups compared to SL indicating improved hippocampal maturation. No differences in hippocampal lipid composition or short-term memory were observed between groups. In conclusion, emulsification of fat globules in infant formula with dairy-derived emulsifiers altered the plasma lipid profile and hippocampal tissue diffusivity but had limited effects on other absorptive and learning abilities relative to SL in preterm piglets. 相似文献

The capacity of patients infected with human immunodeficiency virus (HIV) to develop an adequate antibody response to influenza vaccination in relation to the CD4 cell count has been studied in a prospective study. A total of 73 subjects (54 HIV-infected patients and 19 healthy control persons) were vaccinated with influenza subunit vaccine containing 15 μg hemagglutinin of each of the following strains: A/Beijing/353/89(H3N2), A/Singapore/6/86(H1N1), B/Panama/45/90, and B/Beijing/1/87. Hemagglutinin inhibition (HI) antibody titers were determined prior to vaccination, 3 weeks afterwards, and at the end of the influenza season. The percentage of subjects with HI antibody titers above the assumed protective level was significantly lower in the HIV-infected patients for all 4 vaccine strains compared with those in the control group (7–26% and 42–74%, respectively). There was an association between CD4 cell count and antibody response to the B/Panama strain only. The serologic response to tetravalent subunit influenza vaccine is severely impaired in the majority of HIV-infected patients compared with control subjects. The results of this study challenges the recommendation to vaccinate HIV-infected patients. 相似文献

We present two cases with intra-operative complications during the placement of intra-medullary hip screw (IMHS). In both
occasions, the implant accidentally breached the anterior cortex of the distal femur. Lateral view with image intensifier
confirmed the perforation. This intra-operative complication has not been reported before. It is unclear how often this occurs
and how often we miss these subtle complications with potentially disastrous consequences. In the event that it does occur,
it is arguable whether any intra-operative or post-operative precautions should be taken. Intra-operative complications with
particular reference to femoral fractures is a risk, which when occurring could drastically change the course of management.
Although this can be subtle, in general, this will be easily visible on image intensifier. On the other hand, femoral shaft
perforations can be a lot more subtle if they are noticed at all. If this complication is not noted and the management does
not take this into account, a consequential fracture (eg. Supracondylar or peri-prosthetic) and further complications can
result. Possible causes for femoral cortex breaching can be numerous. It is questionable if the breaching is noted whether
it should be protected with further internal fixation, casting support or altering the weight-bearing state post-operatively.
In one of our cases, the surgeon used extra-medullary device (LISS plate) and for the other, the surgeon managed this conservatively.
Different surgeon different management but similar good outcome. 相似文献
