The Concept of Diminished Responsibility in Supranational Criminal Law (Psychiatric Approach)

The role of the community management order (CMO) in the management of mental illness has been associated with controversy. There is uncertainty as to the effectiveness of such involuntary treatment. Review of outcomes of involuntary community treatment has shown varied results, and in the remote areas of Australia the issue becomes more complex, and outcomes more difficult to measure. The Northern Territory's Mental Health Act 2000 has broadened criteria for detention. The decision to impose follow-up and case management on an individual (who may reside in a community several hundred kilometres from an in-patient facility) requires careful consideration of its ethical, professional and psychosocial implications. The trend toward increasing use of mental health legislation in the Northern Territory — particularly for Indigenous people — deserves close scrutiny in order that culturally appropriate and sensitive treatment plans are developed.

清开灵与利巴韦林治疗小儿呼吸道合胞病毒肺炎的比较：单盲、随机、平行对照试验

目的:比较清开灵与利巴韦林对呼吸道合胞病毒肺炎患儿治疗效果的差异。方法:选择2005-02/2006-04在北京儿童医院分中心治疗的小儿呼吸道合胞病毒肺炎97例,患儿法定监护人知情同意。采用单盲、随机、平行对照试验的原则,按区组随机化方法分为2组,清开灵注射液组49例,利巴韦林组48例。①清开灵注射液组:清开灵注射液静脉滴注加口服中成药。②利巴韦林组:利巴韦林注射液静脉滴注加口服复方愈创木酚磺酸钾口服液。两组疗程均为10d,比较两组患儿的疗效。结果:清开灵注射液组脱落3例,利巴韦林组脱落1例,进入结果分析清开灵注射液组46例,利巴韦林组47例。①清开灵注射液组发热患儿体温恢复正常时间比利巴韦林组短[(2.72±1.86)d,(6.29±2.41)d(P<0.01)]。②清开灵注射液组患儿咳嗽、痰壅、气促症状积分改善方面优于利巴韦林组(P<0.05～0.01)。③清开灵注射液组的呼吸道合胞病毒转阴时间明显优于利巴韦林组。④咳嗽、痰壅、病毒转阴时间、气促均进入Logistic模型,其中前两个症状的回归系数绝对值较大。结论:清开灵注射液治疗小儿呼吸道合胞病毒肺炎在退热、止咳平喘、呼吸道合胞病毒转阴时间等方面均具有明显优势,咳嗽、痰壅这两个症状更能反映清开灵注射液的疗效优于利巴韦林。     

DIGITAL ISCHAEMIA: AN UNUSUAL PRESENTATION OF DYSBARISM

SUMMARY Dysbaric symptoms following ascent from a scuba dive are due to symptomatic nitrogen or air emboli with clear patterns of associated injury. This case report highlights an unusual presentation of dysbaric injury treated successfully with a prostacyclin analogue.     

Activated human monocytes inhibit the intracellular multiplication of legionnaires’ disease bacteria

We have examined the interaction between virulent egg yolk-grown L. pneumophila, Philadelphia 1 strain, and in vitro-activated human monocytes, under antibiotic-free conditions. Freshly explanted human monocytes activated by incubation with concanavalin A (Con A) and human lymphocytes inhibited the intracellular multiplication of L. pneumophila. Both Con A and lymphocytes were required for activation. Con A was consistently maximally effective at greater than or equal to 4 μg/ml. Monocytes activated by incubation with cell-free filtered supernatant from Con A-sensitized mononuclear cell cultures also inhibited the intracellular multiplication of L. pneumophil a. The most potent supernatant was obtained from mononuclear cell cultures incubated with greater than or equal to 15 μg/ml Con A for 48 h. The degree of monocyte inhibition of L. pneumophila multiplication was proportional to the length of time monocytes were preincubated with supernatant (48 {greater than} 24 {greater than} 12 h) and to the concentration of supernatant added (40 percent {greater than} 20 percent {greater than} 10 percent {greater than} 5 percent). Monocytes treated with supernatant daily were more inhibitory than monocytes treated initially only. With time in culture, monocytes progressively lost a limited degree of spontaneous inhibitory capacity and also lost their capacity to respond to supernatant with inhibition of L. pneumophila multiplication. Supernatant-activated monocytes inhibited L. pneumophila multiplication in two ways. They phagocytosed fewer bacteria, and they slowed the rate of intracellular multiplication of bacteria that were internalized. As was the case with nonactivated monocytes, antibody had no effect on the rate of intracellular multiplication in supernatant-activated monocytes. Neither supernatant-activated nor nonactivated monocytes killed L. pneumophila in the absence of antibody. Both killed a limited proportion of these bacteria in the presence of antibody and complement. We have previously reported that anti-L, pneumophila antibody and complement neither promote effective killing of L. pneumophila by human polymorphonuclear leukocytes and monocytes nor inhibit the rate of L. pneumophila multiplication in monocytes. These findings and our present report that activated monocytes do inhibit L. pneumophila multiplication indicate that cell-mediated immunity plays a major role in host defense against Legionnaires’ disease.     

Stage-specific expression of c-kit protein by murine hematopoietic progenitors

We have analyzed c-kit expression by hematopoietic progenitors from normal and 5-fluorouracil (5-FU)-treated mice by staining with monoclonal anti-c-kit antibody ACK-4. Marrow cells that were enriched for progenitors by a combination of metrizamide density separation and negative immunomagnetic selection with lineage-specific monoclonal antibodies (MoAbs) were separated into three populations based on the level of c-kit expression, c-kit(high), c-kit(low), and c-kit-. The majority of colony-forming cells from normal mice were in c-kit(high) population, whereas most of the progenitors from 5-FU-treated mice were in the c-kit(low) population. Optimal colony formation from c-kit(low) cells from 5-FU-treated mice required the interactions of at least two factors among interleukin-3 (IL-3), IL-11 and steel factor (SF) whereas colony formation from c-kit(high) cells of normal mice was supported well by IL-3 alone. Blast cells that were derived from 5-day culture of c-kit(low) post 5-FU cells were c-kit(high). These observations suggest that the primitive hematopoietic progenitors in cell cycle dormancy are c-kit(low) whereas actively cell cycling maturer progenitors are c- kit(high). Mature cells, with the exception of mast cells, derived from secondary culture of the c-kit(high) blast cells expressed little, if any, c-kit. These results are consistent with a model in which c-kit expression progresses from low levels on primitive, dormant multipotent progenitors to high levels on later, actively cycling progenitors, and finally, decreases to very low or undetectable levels on most mature blood cells, with the exception of mast cells.
