Every neurosurgeon can appreciate Dandy's recognition that the drainage of brain abscesses causes trauma to the delicate parenchyma. Over the years, brain surgery has evolved toward management of problems by using less and less invasive techniques and thus gaining ever lower morbidity. Clearly, the advent of better imaging techniques has improved the outcome in patients afflicted with intracerebral infections. The combination of stereotaxy with these imaging techniques is contributing a "zero mortality" in the treatment of these infections. In our series of 29 consecutive patients with non-AIDS-related infections, no patient died as a direct result of a stereotactic surgical procedure. Two patients (7%) had new neurologic deficits after surgery. The only patient left with a permanent disability had a kidney allograft and subacute bacterial endocarditis. His condition deteriorated 6 hours after aspiration of a sterile abscess, when an intra-abscess hematoma was diagnosed and evacuated. In retrospect, this complication may have been avoided by less vigorous aspiration. Three of the four patients with nonviral infections who died were iatrogenically immunosuppressed for their organ transplants. These patients are difficult to treat, and given the current popularity of transplantation procedures, neurosurgeons will face more and more opportunistic infections. In general, the patients with abscesses did well. On the other hand, nonoperative mortality was extremely high for patients with viral encephalitides. This high mortality may have resulted from a delay in diagnosis and treatment or from the unavailability of highly effective antiviral agents at the time the biopsies were performed. The importance of early diagnosis and treatment of infection cannot be overemphasized. T.H. Flewett's warning about the management of HSE applies to the management of all cerebral infections: "It seems clear from everybody's published results [in the papers already given] if we wait to do biopsy until the clinical indications are unmistakable, we have waited so long that the patient, if he survives, will be left a severe neurological cripple." Because it is relatively noninvasive, stereotactic neurosurgery has been used increasingly to diagnose brain masses in patients with AIDS. We recommend its use for establishing diagnoses in all suspected cases of cerebral infection. We agree with Rosenblum et al: Empiric treatment of brain infections should be regarded as "radical." Such treatment should be reserved for patients who have an identifiable source of infection and causative organism or for patients who are clinically too unstable to undergo surgery.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

We have explored the polymorphism of the glycophorin system in the human erythrocyte membrane using the immunoblotting techniques and examining 52 individuals selected without prior bias as to their serologic state and ten documented serologic variants of M, N, S, s blood group system. Polyclonal antisera to alpha glycophorin and to alpha glycophorin CNBr carboxyl terminal fragment C (residues 82-131) and M and N specific monoclonal antibodies (MoAbs) were used. The first two reagents detect specific regions of the alpha glycophorin molecule and all electrophoretically resolved species of glycophorins immunologically related to alpha and delta glycophorins (delta glycophorin, [alpha-delta] hybrids and other glycophorins with an alteration in the carboxyl terminal segment); the M and N MoAbs identified the glycophorin species containing or lacking the M or N determinant in the amino terminal octapeptide structures. We find that immunoblotting confirmed in all cases the serologically determined phenotype; we also find that polymorphic forms of the glycophorin system are relatively infrequent; immunoblotting, independent from serologic testing, was capable of detecting five mutants, two most likely S-s-U-phenotypes; a new glycophorin species was detected in normal red cells with both antiglycophorin and antipeptide C sera, which is not evident with MoAbs; immunoblots of known glycophorin variants (En(a-), U-, Mg, Mi I, II, III, V, and Sta) confirmed but also extended our knowledge of the abnormal glycophorins involved; and the He+ and Wrb(-) cells showed normal patterns.  相似文献

Meningoencephalitis and brain abscess due to a free-living amoeba   总被引:2,自引:0,他引:2  
A 47-year-old diabetic woman developed fatal meningoencephalitis due to a free-living amoeba. The responsible organism appeared to be neither Naegleria nor Acanthamoeba-Hartmannella. Both acute and chronic (granulomatous) inflammatory reactions of the brain were present, and both cysts and trophozoite forms were readily visualized. The latest classification and methods of identification of such amoebae are reviewed and their threat to public health underscored. It should be realized that a variety of free-living amoebae exist in nature, which potentially can produce meningoencephalitis in humans, and that none of these organisms should be labeled or considered as "avirulent" or "nonpathogenic" until proved otherwise.  相似文献

BackgroundGender-Based (GB) intimate partner violence is a social and public health issue globally. Several risks of violence related to male sexual partners’ perpetration of intimate partner violence (IPV) following the disclosure of their female intimate partners’ HIV + status have been reported. No research has been conducted on male sexual partner’s perspectives of perpetrating IPV following their female intimate partners’ disclosure of human immunodeficiency virus (HIV) seropositive status as a risk factor for the perpetration of IPV in Ghana.ObjectiveThe objective of this study is to explore and describe male sexual partners’ views or perspectives of perpetrating IPV following their female intimate partners’ disclosure of being HIV positive in Ghana.MethodsInterpretive phenomenological approach was used to collect and analyse data from a purposive sample of 18 Male participants whose female intimate relations informed them of being HIV + in Ghana. The sample population was taken from Ghana because such research has been reported elsewhere but none has been done in Ghana. A semi-structured interview guide was used to collect the data. The interview guide covered topics such as background information, participants’ reaction to HIV positive disclosure, lived experiences of participants, and Participants’ understanding of different forms of IPV.ResultsThe findings of this study reveal five main themes that emerged from the interviews which include views on the perpetration of emotional, psychological, and verbal abuse; views on the perpetration of sexual deprivation; views on the perpetration of social isolation; views on the perpetration of financial abuse and views on escalated perpetration of physical abuse.ConclusionFrom the data, HIV positive status disclosure served as a risk factor for different forms of GB IPV against HIV positive women in Ghana, thus making this group more vulnerable and exposed to more GB IPV. Strategies to prevent the perpetration of IPV against women newly diagnosed as HIV positive are needed. We recommend screening all newly diagnosed HIV-positive women for abuse as an additional prevention strategy for IPV associated with disclosure of positive HIV status.

KEY MESSAGES

  • HIV positive status disclosure serves as a risk for the perpetration of IPV.
  • Men are predisposed to violence upon hearing that their female heterosexual intimate partners are HIV positive.
  • HIV infection information is distressful to receive from an intimate partner.
