A preliminary study of the relationship between antibiotic administration and changes in bacteriological profile of wound infection in a burn unit

Objective:To investigate the relationship between antibiotic administration and the changes in bacteriological profile in a burn unit. Methods: The data of consumption of different kinds of antibiotics, including total antibiotic consumption [expressed as the number of defined daily doses (DDD)] as well as pathogen identification, were collected in a 8-year period. The constituent ratios of different kinds of antibiotics in total antibiotic consumption to isolation rates of various species of bacteria were calculated, and their correlation was analyzed. Results: Within this period, it was found that the aminoglycosides and first generation cephalosporins were used less frequently, while the polypeptides, carbopenem and macrolides were used proportionally more. At the same time, the isolation rates of Staphylococcus aureus, Acinetobacter sp, Enterobacter cloacae, Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus were gradually increased. The constituent ratios of predominant pathogens were correlated to the different kinds of antibiotics consumption in the burn unit. Conclusion: The results suggested that the consumption of different antibiotics was closely related to the trends of emergence of bacterial isolates from infected burn wounds. The result might imply that to regulate the administration of certain antibiotics might help decrease the emergence of certain pathogenic bacteria in burn infections.     

Breast cancer surveillance — a cost-effective strategy

Summary The effectiveness of a surveillance program for breast cancer recurrence in extending survival is predicated on two assumptions: 1) most recurrences are detected at an early stage at surveillance visits; and 2) the early treatment of recurrence offers a better chance of cure or longer survival. However, the data suggest that neither of these two assumptions is correct, and that postoperative follow-up of patients with breast cancer is expensive and does not significantly extend survival.This minisymposium was presented December 8, 1992, at the annual San Antonio Breast Cancer Symposium, and was sponsored by educational grants from Amgen and from Bristol-Myers Oncology Division.

苯妥英钠血清浓度监测（31例报告）

报告31例口服DPH治疗的门诊癫痫病人RIA法血清DPH浓度监测结果。在随访中记录的临床治疗反应。病人平均药物剂量为4．39±1．19mg/kg／d，不同病人服用同一剂量DPH，其血清药物旅度可相差9倍。22例获良好(较好)的治疗反应，其平均有效血清药物浓度为24．1±10．1μg／ml。9例出现中毒反应；血清药物浓度在25μg／ml以上时可出现眼球震颤、视物模糊，共济失调。DPH血清浓度监测有功于实现个体化给药方案，提高疗效并避免中毒。     

Anal and rectal cancer in Crohn's disease

Several epidemiological studies have been published regarding the risk of Crohn's disease‐ associated colorectal cancer. The findings are, however, contradictory and it has been particularly difficult to obtain indisputable information on the incidence of cancer limited to the rectum and the anus. During 1987–2000 rectal or anal cancer was diagnosed in 335 patients in Sweden (153 males, 182 females). In other words, approximately 3 Crohn patients per million inhabitants were diagnosed with rectal or anal cancer every year during that time period which is 1% of the total number of cases. At diagnosis of cancer 36% were aged below 50 years and 58% below 60 years. Corresponding figures for all cases of anal and rectal cancer were 5% and 18%, respectively. Present knowledge from the literature implies that there is an increased risk of rectal and anal cancer only in Crohn's disease patients with severe proctitis or severe chronic perianal disease. However, the rectal remnant must also be considered a risk factor. Multimodal treatment is similar to that in sporadic cancer but proctectomy and total or partial colectomy is added depending on the extent of the Crohn's disease. The outcome is the same as in sporadic cancer at a corresponding stage but the prognosis is often poor due to the advanced stage of cancer at diagnosis. We suggest that six high‐risk groups should be recommended annual surveillance after a duration of Crohn's disease of 15 years including extensive colitis, chronic severe anorectal disese, rectal remnant, strictures, bypassed segments and sclerosing cholangitis.     

MANAGEMENT OF SEMINOMA OF THE TESTIS: RECOMMENDATIONS BASED ON TREATMENT RESULTS

Background : The results of management of seminoma of the testis at the Department of Radiation Oncology St Vincent's Hospital, Sydney were evaluated retrospectively to: (i) establish that outcomes were in keeping with published results from centres in Australia and overseas; (ii) assess the impact of chemotherapy on management; and (iii) to determine ‘best practice’ management protocols based on our results and a review of the relevant literature. Methods : (i) Assessment of treatment results for stage I and II seminoma of the testis treated by post-orchidectomy radiotherapy and/or chemotherapy at St Vincent's Hospital between 1979 and 1993; (ii) literature review of published data from Australian and overseas centres on the management of seminoma of the testis, and in particular the use of surveillance or chemotherapy either alone, at time of relapse or combined with radiotherapy; and (iii) development of recommendations for use as management protocols in our department. Results : Our data and a review of the literature suggest that post-orchidectomy radiotherapy with chemotherapy for relapse in stage I and IIA disease results in long-term cure rates approaching 100%. Treatment with chemotherapy either routinely or selectively or using a surveillance policy is unlikely to show any improvement in outcome and may be less cost-effective and/or produce increased morbidity and the risk of secondary leukaemia. For stage IIB disease (5–10 cm) the use of initial combination chemotherapy with or without subsequent radiotherapy did not appear to give better outcomes than initial radical radiotherapy alone, reserving chemotherapy or further radiotherapy for relapse. For bulkier stage IIB disease (> 10cm). the use of initial chemotherapy plus consolidation radiotherapy appeared to be an appropriate treatment. Conclusions : Management protocols for seminoma of the testis at St Vincent's Hospital, Sydney Department of Radiation Oncology currently are (i) stage I, IA and IIB (5–10 cm): post-orchidectomy radiotherapy alone with chemotherapy or further radiotherapy for relapse; and (ii) stage IIB (> 10 cm) disease: initial chemotherapy post-orchidectomy followed by radiotherapy to sites of initial disease involvement.

Quantification of risk factors in Hospital infection at a surgical service

In this paper we have analyzed several risk factors for developing nosocomial infections at a Surgical Service of the Hospital Clinico Universitario San Cecilio 2>, based on a retrospective follow-up program designed specifically for this study. Of all patients admitted to the Service from January 1 to June 17, 1987, we examined the following variables: age, sex, cause of admission, emergency or non-emergency admission, operation and related variables. The overall rate of nosocomial infections was 16.46%. The most significant risk factors we found were operation , which had a linear correlation coefficient of '0.929 (p < 0.01) with hospital infection when stratified by its lenght, advanced age ( >60 years old), especially in non-operated patients, and chemoprophylaxis. Such risk factors were ascertained taking into account the confounding effect produced by the variables studied in this survey.Corresponding author.
