An iatrogenic intramural hematoma (IMH) localized in the ascending aorta is a rare and potentially life-threatening complication following percutaneous coronary intervention (PCI). We describe the case of an ascending aortic IMH after the PCI of an anomalous right coronary artery. Early extension of the hematoma was observed during transesophageal echocardiography; the patient underwent successful surgical repair.  相似文献

BACKGROUND: Numerous abdominal and perineal operations have been described for the treatment of complete rectal prolapse. We describe our results with Devadhar's rectopexy, which avoids dissection in the presacral space and hence may be expected to have a low risk of sexual and urinary disturbances. METHODS: Case records of 72 consecutive patients (40 men), aged above 18 years, with complete rectal prolapse who were treated with Devadhar's operation were reviewed. RESULTS: The only complication observed was mucosal prolapse in 3 patients. None of the 40 men had erectile dysfunction or retrograde ejaculation after a median follow-up of 10 (range 3-48) months. No patient had disturbance in micturition. Two patients (2.7%) had recurrence of rectal prolapse. In four patients (8.5%), constipation persisted. CONCLUSION: Devadhar's rectopexy for complete rectal prolapse was not associated with disturbances in sexual or micturition function, and low rates of recurrence of prolapse.  相似文献

Malignant chondroid syringoma (MCS) is a rare tumor, of the sweat gland; only a few hundred such cases are reported in literature. A female presented with a subcutaneous swelling on the scalp with repeated recurrence and positive regional lymph nodes. Adequate planning for the treatment of this case was possible as preoperative diagnosis of MCS was documented by fine needle aspiration cytology (FNAC). The case was successfully managed with a multimodal approach, which included radical surgery and subsequent radiotherapy. The patient is symptom free after 25 months. The possibility of this type tumor should be entertained when multiple recurrences occur following adequate excision. FNAC has a definitive role in planning rational therapy.  相似文献

The effect of an intrauterine foreign body (IUFB) on the incorporation of acetate-1-14C into endometrial lipids, RNA and protein was studied in baboons. Thirty minutes after the intraluminal instillation of the radioprecursor, the control endometrium was found to contain about three times as much total radioactivity as the IUFB endometrium. However, the percentage of total tissue radioactivity which was incorporated into tissue macromolecules was 3–5 times greater in the IUFB than in the control endometrium. The tissue content of RNA and protein per unit tissue DNA was significantly lower and the specific activities of RNA and protein were significantly higher in the IUFB than in the control endometrium. These findings suggest that an IUFB may stimulate the turnover of macromolecules in baboon endometrium.  相似文献

Sustained-release Morphine for Epidural Analgesia in Rats   总被引:4,自引:0,他引:4  
Background: Epidural opioid analgesia often requires either continuous infusion or repeated injections, which are inconvenient for patients, increase risk of infection, and consume expensive physician and nursing time. In addition, potential respiratory depression is a major safety concern. The authors studied whether a single dose of epidurally administered, sustained-release morphine could prolong analgesia and reduce toxic effects in rats.

Methods: Sustained-release morphine (DTC401) was prepared by encapsulating morphine sulfate in DepoFoam (Dep. Tech, San Diego, CA), a lipid-based, sustained-release drug delivery system. A standard hot-plate test for analgesia, pulse oximetry for hemoglobin oxygen saturation, corneal-reflex loss, and incidence of catalepsy were used to assess efficacy and toxicities. Cerebrospinal fluid and serum pharmacokinetic studies were performed after a single epidural dose, using a commercially available radioimmunoassay kit.

Results: Single epidural doses of DTC401 resulted in equivalent onset time to peak analgesia but significantly prolonged analgesia compared with morphine sulfate. Hemoglobin oxygen saturation was decreased minimally, and the incidences of catalepsy and corneal-reflex loss were minimal, even at large doses of DTC401. In contrast, the larger doses of morphine sulfate significantly decreased hemoglobin oxygen saturation, and caused catalepsy and loss of the corneal-reflex. The Cmax for DTC401 was 32% in cerebrospinal fluid and 6% in serum, relative to morphine sulfate. The terminal half-life for DTC401 was increased 32 fold in the cerebrospinal fluid compared with morphine sulfate.  相似文献

305 throat swab culture & sensitivity reports were reviewed from the records of Microbiology department of Shri V.N. Govt. Medical College, Yavutmal. 130 reports were showiβg, growth of pathogenic organisms. Out of this, 771 eports were showing coagulase positive staphylococci; 32 were showing group A b haemolytic streptococci. A bimodal peak of pathogenic organism growth was observed in the month of March and from August to October. Analysis of culture and sensitivity reports, showed that amongst many, erythromycin - a time tested, comparatively cheap and reliable drug - has very good sensitivity spectrum. Cefotaxime, tetracyline, penicillin and gentamicin were also found to be useful. Emerging resistance to some newer antibiotics is a matter of concern and hence authors advocate the formulation of effective antibiotic policy at the national and loco- regional levels.  相似文献

Subcellular fractions of mice thymocytes were used for sensitization of rabbits. The antisera were examined for their immunosuppressive potency in vivo by allogeneic murine tumor metastases system and on skingraft survival and in vitro by leukocyte agglutination tests. The results indicated that the most potent immunosuppressive antisera was that against the second fraction (Fr. 2) of the detergent soluble endoplasmic reticulum fraction from thymocytes.  相似文献

1. Procedures are described for the extraction and partial purification of dog renin, on a large scale, as well as for the acetylation of rat, rabbit, and dog renin. 2. Untreated homologous renin was not antigenic in rat, rabbit, or dog, but the acetylation of homologous renin made it antigenic. 3. Immunization of rats, rabbits, and dogs, with acetylated rat, rabbit, and dog renin, respectively, resulted in each case in the development of anti-renin to the homologous, untreated, as well as to the acetylated renin. 4. The progressive development of antirenin as a result of repeated, subcutaneous injections of acetylated dog renin, in a dog with experimental renal hypertension for more than 6 years, was accompanied by a correspondingly progressive fall of the mean arterial blood pressure to the prehypertensive level. This points up the important part played by the renin-angiotensin mechanism in the maintenance of the hypertension, even in the chronic phase of experimental renal hypertension.  相似文献
