Chronic and intermittent abuse of one family member by another is common. Victims may be children who are sexually or physically abused, wives or live-in partners, or older relatives. Physicians are often the first points of contact for patients who have been abused, but the abuse is frequently concealed by the victims. Physicians should be alert to signs of battering such as bruises in various stages of healing, unusual behaviour in children and interpersonal difficulties in the family. There are a number of options in prevention and treatment, including referral to social service and legal authorities, calling on other resources in the family and helping the individual develop coping skills. This review also lists a large number of social agencies in Canada that are willing to help victims of abuse. 相似文献

Echo-guided endomyocardial biopsy in heart transplant recipients 总被引:1,自引:0,他引:1

After heart transplantation the effect of immunosuppression is monitored by histopathology of endomyocardial biopsy (EMB). EMB is usually carried out under X-ray guidance. Between January 1998 and March 2003, 1,262 biopsies were collected under echo-guidance in 156 patients. The biopsy access was gained through the internal jugular vein, by the standard catheterization technique. The average time of the procedure was 17 min. Four or five specimens were obtained from each patient, with a success rate of 96%. Complications involved two episodes of partial pneumothorax in one patient, atrial flutter in another and ventricular fibrillation in three patients. Conversion from echo to X-ray guidance was indicated in 11 patients. No case of significant tricuspid regurgitation related to the EMB procedure was recorded. The echo-guided endomyocardial biopsy appears to be a prospective alternative to the conventional approach under X-ray guidance. Its duration is comparable, it eliminates X-ray exposure, enables continuous echocardiographic monitoring and can be performed at the bedside. 相似文献

BACKGROUND: The treatment of recurrent laryngeal papillomatosis still presents an important therapeutic problem. This primarily benign disease of the larynx is caused by an infection with the human papilloma virus (HPV) and forms epithelial neoplastic papillomas. Therapy in larynx obstructing papillomatosis usually requires laser ablation. Cidofovir acts virustatically as an nucleosidanalogon. Currently pilot studies investigate the effectiveness of intralesional Cidofovir injection. PATIENTS AND METHODS: The present study covers the period from October 2001 to March 2003. Seven patients, age of five to 70 years, were treated with intralesional injections of Cidofovir after microlaryngoscopic ablation of laryngeal papillomas. In all patients papillomatosis was confirmed histologically and a clinical-phoniatric examination and a photo documentation pre- and postoperatively was carried out. We treated patients to a maximum of six sessions. RESULTS AND CONCLUSIONS: After three to six sessions of laser ablation of the papillomas and intralesional injections with Cidofovir a distinct papilloma reduction could be observed in all patients and in two cases a complete remission was achieved. The follow-up period of seven to 15 months revealed no recurrent laryngeal papillomatosis. The majority of patients showed a defined voice improvement. There were no local or systemic side-effects caused by the virustatic drug. Intralesional injection of Cidofovir appears to develop into a promising adjuvant therapy option in recurrent laryngeal papillomatosis. First results of the study seem to achieve a considerable reduction of the previously high rate of recurrence of laryngeal papillomatosis. 相似文献

Use of hyperbaric oxygen chamber in the management of radiation-related complications of the anorectal region 总被引:3,自引:0,他引:3
PURPOSE: This article was undertaken to present two cases of nonhealing ulcers that occurred after primary radiation therapy and local excision of suspected residual or recurrent anal carcinomas. Both patients responded favorably to hyperbaric chamber treatment. Review of the literature is discussed, including cause, clinical presentation, diagnosis, and options for management of radiation-related complications in the anorectal region and use of hyperbaric oxygen treatment in colorectal surgery. METHODS: The cases of two patients with recurrent or residual anal carcinomas were reviewed. Objective clinical, laboratory test, and intraoperative findings were implemented to define this pathologic entity precisely, results of its treatment, and management of radiation-related complications. RESULTS: The study shows clinical effectiveness of hyperbaric chamber treatment for nonhealing wounds in the previously radiated anorectal region. The refractory wounds of both our patients healed. The patients were rendered free of symptoms. CONCLUSIONS: Substantial pathologic changes in the irradiated tissues leading occasionally to nonhealing radiation proctitis are relatively infrequent consequences of radiation therapy for pelvic malignancies. Excisional and incisional biopsies of the radiation-injured tissues result in chronic ulcers accompanied by debilitating symptoms. Hyperbaric chamber treatment seemed to be a very effective means of therapy of radiation proctitis and nonhealing wounds in the involved anorectal region after conventional therapy had failed. 相似文献

Francisella tularensis is a Gram-negative, facultative intracellular bacterium causing disease in many mammalian species. The low infectious dose of F. tularensis and the ease of air-borne transmission are the main features responsible for the classification of this bacterium as a potential biological weapon. The live attenuated strain of F. tularensis live vaccine strain (LVS) is currently only effective vaccine against tularemia, however, this type of vaccine has not been approved for human use. In the presented study, sub-immunoproteome analysis was performed to search for new immunogenic proteins of Francisella tularensis LVS grown under different conditions. By this approach 35 immunoreactive antigens were identified, 19 of them showed to be novel immunogens. In conclusion, sub-immunoproteome analysis resulted in successful identification of novel immunoreactive proteins. 相似文献

Manipulation and mobilisation are often used, either alone or combined with other treatment approaches, to treat neck pain. This review assesses if manipulation or mobilisation improves pain, function/disability, patient satisfaction, quality of life (QoL), and global perceived effect (GPE) in adults experiencing neck pain with or without cervicogenic headache or radicular findings. A computerised search was performed in July 2009. Randomised trials investigating manipulation or mobilisation for neck pain were included. Two or more authors independently selected studies, abstracted data, and assessed methodological quality. Pooled relative risk (pRR) and standardised mean differences (pSMD) were calculated. 33% of 27 trials had a low risk of bias. Moderate quality evidence showed cervical manipulation and mobilisation produced similar effects on pain, function and patient satisfaction at intermediate-term follow-up. Low quality evidence suggested cervical manipulation may provide greater short-term pain relief than a control (pSMD ?0.90 (95%CI: ?1.78 to ?0.02)). Low quality evidence also supported thoracic manipulation for pain reduction (NNT 7; 46.6% treatment advantage) and increased function (NNT 5; 40.6% treatment advantage) in acute pain and immediate pain reduction in chronic neck pain (NNT 5; 29% treatment advantage). Optimal technique and dose need to be determined. 相似文献
