Abscesses in the gastric wall are extremely rare. As the mucosa remains intact in most cases, clear differential diagnosis is required in order to distinguish the condition from the more frequent intramural mesenchymal tumors. Endoscopic ultrasonography provides a valuable tool for imaging intramural tumors, but this approach does not allow a definitive assessment of malignancy. We report about two patients with intramural abscesses in the gastric wall. Endosonography showing eccentric tumors from the gastric wall in the two patients. The endosonographic image was inhomogenous, the wall layer structure of the gastric wall was not preserved. A laparotomy was carried out on the first patient. In the second case, the diagnosis was easy, as pus was emptying from a small opening in the mucosa, which had already been detected at gastroscopy. Endoscopic intervention was carried out based on the endosonographic findings. In one patient, mucosa and submucosa were opened by a needle knife. These cases show that gastric wall abscesses do not have a typical endoscopic ultrasound appearance. However, endosonography is an essential method prior to endoscopic interventional therapy. 相似文献

The erbium-doped fiber amplifier (EDFA) with regenerative feedback is compared with the cofeedback scheme. Without the bandpass filter, the injected signal experiences regenerative amplification and results in a higher signal gain. Such an above-threshold regenerative amplifier also exhibits a lower noise figure due to a higher inversion for the transition corresponding to the signal wavelength of 1550 nm. A near quantum-limited noise figure of 3.1 dB is achieved at the maximum pump power of 134.5 mW, showing nearly complete inversion at the EDF input end in the regenerative-feedback scheme. A low (<10/sup -10/) bit-error rate has been achieved with saturation input signal power above -12 dBm. 相似文献

In cases of congenital lymphoedema the finding of ulceration, violaceous nodules or papules, or apparent traumatic ecchymoses should act as a diagnostic beacon warning of dangers. A case is reported of a high-grade angiosarcoma developing in a patient with congenital hereditary lymphoedema (Milroy's disease). This is the second paper to report this complication, the third case report and the first case in which the diagnosis is substantiated by immunohistochemistry and lectin histochemistry. A review of cases of angiosarcoma complicating congenital hereditary and non-hereditary lymphoedema is also presented. 相似文献

The Internet explosion and the possibility of direct digital interaction with large numbers of home consumers presents tremendous opportunities, and challenges, to the financial services community. Today's providers must reckon with the Internet and on-line services, or potentially lose prime customers to new, nontraditional players. In this paper, the design and development details of an on-line banking (OLB) application for one of the banks in Singapore have been described. The implementation of OLB requires the creation of website, webpages and links to other related information. It further allows the users to submit a loan application for computing installments for repayment and other related information. Two of the popular languages of Internet have been used for the implementation of OLB. Due to proprietary nature of the application, certain implementation details are not provided in this paper. 相似文献

Delusional jealousy is an important subject for forensic psychiatry because of its well-known association with violence, especially as directed toward spouses. In this article, we report a study of 20 individuals who suffered from delusional jealousy. Important biopsychosocial parameters, the relation between jealousy and aggression, and directions for future study are explored. 相似文献

To establish whether lispro may be a suitable short-acting insulin preparation for meals in intensive treatment of Type 1 diabetes mellitus (DM) in patients already in chronic good glycaemic control with conventional insulins, 69 patients on intensive therapy (4 daily s.c. insulin injections, soluble at each meal, NPH at bedtime, HbA1c <7.5%) were studied with an open, cross-over design for two periods of 3 months each (lispro or soluble). The % HbA1c and frequency of hypoglycaemia were assessed under four different conditions (Groups I-IV). Lispro was always injected at mealtime, soluble 10-40 min prior to meals (with the exception of Group IV). Bedtime NPH was continued with both treatments. When lispro replaced soluble with no increase in number of daily NPH injections (Group I, n = 15), HbA1c was no different (p = NS), but frequency of hypoglycaemia was greater (p < 0.05). When NPH was given 3-4 times daily, lispro (Group II, n = 18), but not soluble (Group III, n = 12) decreased HbA1c by 0.35 +/- 0.25% with no increase in hypoglycaemia. When soluble was injected at mealtimes, HbA1c increased by 0.18 +/- 0.15% and hypoglycaemia was more frequent than when soluble was injected 10-40 min prior to meals (Group IV, n = 24) (p < 0.05). It is concluded that in intensive management of Type 1 DM, lispro is superior to soluble in terms of reduction of % HbA1c and frequency of hypoglycaemia, especially for those patients who do not use a time interval between insulin injection and meal. However, these goals cannot be achieved without optimization of basal insulin. 相似文献

Interactions between the Ca2+ release channel of skeletal muscle sarcoplasmic reticulum (ryanodine receptor or RyR1) and the loop linking domains II and III (II-III loop) of the skeletal muscle L-type Ca2+ channel (dihydropyridine receptor or DHPR) are critical for excitation-contraction coupling in skeletal muscle. The DHPR II-III loop was fused to glutathione S-transferase- or His-peptide and used as a protein affinity column for 35S-labeled in vitro translated fragments from the N-terminal three-fourths of RyR1. RyR1 residues Leu922-Asp1112 bound specifically to the DHPR II-III loop column, but the corresponding fragment from the cardiac ryanodine receptor (RyR2) did not. The use of chimeras between RyR1 and RyR2 localized the interaction to 37 amino acids, Arg1076-Asp1112, in RyR1. The RyR1 922-1112 fragment did not bind to the cardiac DHPR II-III loop but did bind to the skeletal muscle Na+ channel II-III loop. The skeletal DHPR II-III loop double mutant K677E/K682E lost most of its capacity to interact with RyR1, suggesting that two positively charged residues are important in the interaction between RyR and DHPR. 相似文献

OBJECTIVE: Cataracts are a frequent complication after silicone oil infusion for the repair of complicated retinal detachments, occurring in up to 100% of eyes retaining silicone oil for 6 months or more. The authors devised a combined procedure for cataract and silicone oil removal with intraocular lens (IOL) implantation through a single corneal incision and evaluated their results. DESIGN: A prospective, noncomparative case series. PARTICIPANTS: Thirty-four eyes of 34 consecutive patients with a history of retinal detachment repair requiring silicone oil placement in whom a clinically significant cataract subsequently developed were identified when removal of silicone oil was scheduled. INTERVENTION: All 34 eyes were prospectively entered into a study to evaluate the efficacy and potential complications of a combined procedure for cataract and silicone oil removal with posterior chamber lens implantation. All patients underwent uncomplicated phacoemulsification removal of cataract followed by removal of silicone oil and placement of an IOL through a single corneal incision. MAIN OUTCOME MEASURE: Recurrent retinal detachment and IOL-related complications were measured. RESULTS: Ten eyes had recurrent retinal detachments develop. Final visual acuity ranged from 6/12 to hand movements with 25 eyes (74%) showing stabilized or improved vision. Pre-existing macular pathology and recurrent retinal detachment generally were responsible for poor visual outcome. CONCLUSIONS: Combined phacoemulsification, IOL implant with silicone oil removal is a useful procedure in these complicated eyes. Visual outcome generally is good with improvement in visual acuity, even with recurrent retinal detachment or pre-existing macular pathology or both. 相似文献
