Returning to work with aphasia: A case study

Background: For some people with aphasia, returning to work will be their eventual goal. While there are reports in the literature of incidence of return to work, and general discussion of success, there are few documented in depth studies of what this might entail for the individual with aphasia.

Aims: This paper explores returning to work with aphasia, and examines the complex relationship between the person, the aphasia and the demands of employment.

Methods & Procedures: This is a detailed case report, describing and reflecting on the experiences of GD, who returned to work following his stroke and aphasia. Therapy focused specifically on work requirements is described and the factors affecting GD's return to work explored. An interview was used to elicit GD's reflections on his experiences.

Outcome & Results: GD's language skills improved over time and with therapy, and he developed several strategies that facilitated his communication. He was able to return to work (part-time) in a modified role and this was successful initially. After an extended period (～19 months) his employment was terminated and GD explored other options. He moved on to a volunteering and charity trustee role.

Conclusions: The success (or not) of returning to work with aphasia is multi-faceted and does not rest solely with the person with aphasia. The nature of the work may have a strong bearing on success, as will the ability and willingness of the employer to engage in the process. Partnership with the person and constant review of goals and management is of overwhelming importance. We need to consider what “success” may mean in this context and the need to consider therapeutic and rehabilitation needs over a longer time frame.     

Detection of anti-HTLV-I Tax antibodies in HTLV-I enzyme-linked immunosorbent assay-negative individuals

The HTLV-I tax gene protein (Tax) is not packaged within the mature viral particle from which the proteins for the commercially available enzyme-linked immunosorbent assay (ELISA) are derived. Screening of 162 individuals within a cohort of white intravenous (IV) drug abusers, previously identified as having an increased incidence of HTLV-I infection, demonstrated that seven of them had antibodies to the HTLV-I Tax protein but tested negative in HTLV-I ELISAs and Western blots prepared from purified virion proteins. Three out of 35 individuals in other behaviorally defined high-risk groups also displayed this limited pattern of reactivity to HTLV-I proteins. The presence of the anti-HTLV- I p40/Tax antibodies was determined by radioimmunoprecipitation assay (RIPA), which also revealed low levels of anti-env reactivity. The specificity of the anti-p40 reactivity was confirmed on specific Tax ELISAs and Western blots prepared from recombinantly produced Tax. In vitro gene amplification by the polymerase chain reaction (PCR) was used to establish the presence of sequences homologous to HTLV-I proviral DNA in four/four of these HTLV-I ELISA negative, Tax ELISA/Tax western blot/RIPA positive individuals. These data suggest that the true incidence of HTLV-I infection within high-risk cohorts is greater than previously reported.     

A systematic review and meta-analysis of biological treatments targeting tumour necrosis factor α for sciatica

Purpose

Systematic review comparing biological agents, targeting tumour necrosis factor α, for sciatica with placebo and alternative interventions.

Methods

We searched 21 electronic databases and bibliographies of included studies. We included randomised controlled trials (RCTs), non-RCTs and controlled observational studies of adults who had sciatica treated by biological agents compared with placebo or alternative interventions.

Results

We pooled the results of six studies (five RCTs and one non-RCT) in meta-analyses. Compared with placebo biological agents had: better global effects in the short-term odds ratio (OR) 2.0 (95 % CI 0.7–6.0), medium-term OR 2.7 (95 % CI 1.0–7.1) and long-term OR 2.3 [95 % CI 0.5 to 9.7); improved leg pain intensity in the short-term weighted mean difference (WMD) −13.6 (95 % CI −26.8 to −0.4), medium-term WMD −7.0 (95 % CI −15.4 to 1.5), but not long-term WMD 0.2 (95 % CI −20.3 to 20.8); improved Oswestry Disability Index (ODI) in the short-term WMD −5.2 (95 % CI −14.1 to 3.7), medium-term WMD −8.2 (95 % CI −14.4 to −2.0), and long-term WMD −5.0 (95 % CI −11.8 to 1.8). There was heterogeneity in the leg pain intensity and ODI results and improvements were no longer statistically significant when studies were restricted to RCTs. There was a reduction in the need for discectomy, which was not statistically significant, and no difference in the number of adverse effects.

Conclusions

There was insufficient evidence to recommend these agents when treating sciatica, but sufficient evidence to suggest that larger RCTs are needed.

Soluble Fas ligand activates the sphingomyelin pathway and induces apoptosis in luteal steroidogenic cells independently of stress-activated p38(MAPK)

Fas ligand (FasL) is implicated as a mediator of luteolysis. However, a gap exists in our understanding of the Fas-mediated signaling mechanisms that are involved in either the loss of progesterone production or the structural regression of the corpus luteum. In the present study we investigated the acute and chronic effects of FasL with respect to activation of cytokine/stress-induced signaling pathways and apoptosis in bovine steroidogenic cells. More specifically, we investigated soluble FasL (sFasL)-activated production of ceramide, a second messenger of the sphingomyelin pathway, and activation of p38(MAPK), a member of the MAPK family. sFasL activated the sphingomyelin pathway, as evidenced by a 2-fold increase (P < 0.05) in the production of ceramide. Pretreatment with imipramine (50 micro M), an inhibitor of acid sphingomyelinase activity, attenuated (75%; P < 0.05) sFasL-induced ceramide production, suggesting that the increase in ceramide was partially the result of acid sphingomyelinase-mediated hydrolysis of sphingomyelin. Treatment of luteal cells with sFasL or a cell-permeable ceramide analog (C8) for 24-48 h resulted in a significant increase (P < 0.05) in apoptosis. Western blot analysis revealed that sFasL had little effect on the activation of p38(MAPK) in primary bovine luteal steroidogenic cells. Furthermore, pretreatment with the p38(MAPK) inhibitor SB203580 failed (P > 0.05) to inhibit sFasL- or C8-induced death. Although sFasL did not alter basal progesterone levels detected in the culture medium, C8 caused a significant increase (P < 0.05) in progesterone concentrations within the medium. Collectively, these data suggest that the role of FasL in luteolysis may be to activate the stress-induced sphingomyelin pathway that, in turn, serves as a mediator of apoptosis.     

Hepatic decompensation in patients with cirrhosis during infection with influenza A

BACKGROUND: Patients with chronic liver disease can develop hepatic decompensation during systemic infections. Although gram-negative and gram-positive bacteria are well recognized as causes of decompensation, the effect of influenza virus infection on patients with chronic liver disease is poorly documented. METHODS: Retrospective analysis of patients with positive viral cultures who were seen at a liver transplantation clinic in a tertiary care referral center during the 1997-1998 influenza A (H3N2) epidemic in San Diego, Calif. RESULTS: Three patients with end-stage liver disease (1 with Wilson disease and 2 with alcoholic liver disease) developed hepatic decompensation and required hospitalization during infection with influenza A. Two patients had biochemical and clinical evidence of hepatic decompensation, including ascites, hepatic encephalopathy, and peripheral edema, and the third had acute hepatocellular damage, with elevated levels of aminotransferases. Viral hepatitis serologic test results, acetaminophen levels, drug and alcohol screening findings, and bacterial and fungal cultures were negative in all 3 patients. Hepatic decompensation resolved without the need for transplantation in the 2 patients with liver failure, and all patients recovered to their baseline liver function levels within 1 month of onset of acute illness. CONCLUSIONS: Influenza A infection can cause hepatic decompensation and hospitalization in patients having cirrhosis or who are awaiting liver transplantation. Effective prevention with vaccination and early recognition and treatment of influenza are strongly recommended in these individuals.     

Comparing population estimates for drug users, the prevalence of blood-borne viruses and the provision of services in one London borough: Evidence of a gap in provision?

Aims: To estimate the size of the drug-using population in Lambeth, an inner city London borough, and the prevalence of blood-borne virus (BBV) infections in the drug-using population. To identify possible shortfalls in service provision for drug users.

Methods: Direct and indirect estimates of the drug-using population size using national and local data sources. Prevalence estimates for BBV infections were derived from local survey data. Routine data and a survey of borough services for drug users were compiled.

Findings: Based on indirect methods we estimated there were 3117 drug users in Lambeth in 2001-2002 (20 per 1000, 15- to 44-year-olds), of whom 1641 were injecting users (11 per 1000); 1353 were reported as being in drug treatment programmes. BBV prevalence rates: hepatitis B, 37%; hepatitis C, 71%; HIV, 6%. Estimated demand for needle exchange services, in terms of one syringe per injection, and methadone maintenance may be up to double local provision.

Conclusions: More accurate and feasible methods are needed for the routine estimation of the population of drug users. Accurate information is needed for service planning.     

"Wash leather scrotum" (scrotal dermatitis): a treatable cause of male infertility

A group of 16 male patients with infertility had dermatitis of the scrotum and groins giving lichenified oedematous skin; the resulting thickening and loss of rugosity produced a characteristic appearance that we have termed wash leather scrotum. Treatment of the dermatosis resulted in an improvement in sperm count and motility in most patients, and 5 couples produced one or more pregnancies.     

The rare association of right adrenal haemorrhage and renal vein thrombosis diagnosed with duplex ultrasound

Neonatal adrenal haemorrhage with renal vein thrombosis, an almost exclusively left-sided phenomenon, may occasionally be bilateral in the presence of inferior vena cava thrombus but has only twice been reported as confined to the right side. These cases required a combination of ultrasound (USS), excretion urography, cystoscopy with retrograde pyelography, radioisotopes, and CT to diagnose this rare right-sided combination. We report a case of right adrenal haemorrhage causing right renal vein thrombosis accurately diagnosed using only duplex USS and radioisotopes. The potential complications of renal vein thrombosis and hypertension associated with adrenal haemorrhage requires accurate diagnosis and this paper emphasises the value of duplex USS.
