Abstract
Intestinal and extraintestinal complications of Crohn’s disease are well documented. Changes in the connective tissue within the intestinal wall and surrounding tissue including mesenteric fat are characteristically seen in resected and autopsy specimens. A rare and unusually florid mesothelial reaction in the surrounding small bowel serosa of a patient with a 2-year history of Crohn’s ileitis is described. The peritoneal surface of the ileal resection specimen displayed exuberant tubulo-papillary formations of the mesothelium, with superficial invasion of the underlying stroma. The case demonstrates the well-recognised difficult differential diagnosis between a benign mesothelial proliferation and malignant mesothelioma in a novel clinical setting, and the diversity of the extramural manifestations of Crohn's disease.

Abstract
INTRODUCTION A generalized epidemic of HIV infection has been evolving in Papua New Guinea over the last decade, whereas in other Pacific Island countries and territories (PICT) HIV transmission has generally been less widespread. Programmes to detect HIV infection in pregnant women and to prevent mother to child transmission (MTCT) during either delivery or breast-feeding can decrease the incidence of infection in infants. The limited health infrastructure present in some PICT may delay the implementation of effective programmes to decrease MTCT of HIV. METHODS We used a standardized questionnaire to survey health-care providers in 22 PICT for information on the epidemiology of HIV infection and strategies used during 2004 to prevent MTCT of HIV infection in their country. We supplemented these survey responses with data obtained from regional organizations supporting national responses to HIV. RESULTS We obtained responses from 21 PICT. The reported prevalence of known HIV infection was >150 per 100 000 persons in Papua New Guinea, approximately 100 per 100 000 persons in French Polynesia, Guam, New Caledonia and Tuvalu and <50 per 100 000 persons in the remaining 14 PICT. Other than in Papua New Guinea, where an estimated 500 pregnant women had HIV infection diagnosed in 2004, reported HIV infection among pregnant women was rare. Ten PICT reported that an HIV antibody test was offered as a routine component of antenatal care and 11 reported that antiretroviral medications were available for the prevention of MTCT of HIV infection. CONCLUSION The prevalence of HIV infection differs greatly between PICT with a varying risk of MTCT of HIV infection. Successful prevention of MTCT of HIV infection throughout the PICT will require improved uptake of antenatal HIV antibody testing and better access to antiretroviral medications.

Abstract
The frontal assessment battery (FAB) is a bedside test of executive function. It takes less than 10 minutes to administer and a low score indicates executive dysfunction. To determine whether the FAB could detect the more severe subcortical dementia that is a feature of PSP and differentiate it from other bradykinetic rigid syndromes, we studied 17 patients with progressive supranuclear palsy (PSP); 11 with multiple system atrophy (MSA) and 12 with Parkinson's disease (PD). We compared FAB scores with the results of more detailed tests of executive and general cognitive function.FAB scores were significantly lower in PSP than in MSA or PD (p=0.02 and p<0.001) and were also found to be significantly lower in MSA than in PD (p=0.047). We divided the study group into those with an FAB score <15 and those with an FAB score>/=5, regardless of the clinical diagnosis. While 82% of the PSP group had FAB scores of <15, such scores were recorded in only 36% of the MSA and 8% of the PD groups. The lexical fluency and motor series subscores of the FAB discriminated 70% of the PSP, MSA and PD patients. The FAB scores correlated with tests of executive function, as well as with scores on the Mattis Dementia Rating Scale, the Mini Mental State Examination and other tests of general cognitive function. A stepwise regression analysis revealed that across the groups, among the variables that correlated with FAB scores, alternating semantic fluency accounted for 80% of FAB variance.These results suggest that the FAB is a valid and easily applicable bedside test to discriminate executive dysfunction in these three frequently confused bradykinetic rigid syndromes.

Abstract
Solid organ transplantation often leads to the return of fertility in recipients. In females of childbearing age this can be accompanied by a desire to have children. The present paper discusses a planned pregnancy in a heart transplant recipient and outlines important -management issues. These principles of management can be applied to most solid organ transplant recipients.

Abstract
OBJECTIVE To investigate the effects of number of channels and speech-to-noise ratio on connected discourse tracking (CDT) through simulations of cochlear implant speech processing. Previous studies have used citation-form vowel and consonant materials or simple sentences. CDT rates were expected to be less likely to be limited by ceiling effects and more representative of everyday speech communication. DESIGN Four normal-hearing subjects were presented with speech processed through a real-time sine-excited vocoder having three, four, eight, or 12 channels. Amplitude envelopes extracted from each band modulated sinusoidal carrier signals placed at each band center frequency. Speech-spectrum shaped noise was added to speech before vocoder processing at three signal to noise ratios based on real-time measurements of speech level (+7, +12, +17 dB). RESULTS CDT rates increased significantly with number of channels up to eight in both quiet and noise, and decreased significantly with each increase in noise level from quiet. CONCLUSIONS The effects on CDT rates of the number of channels and speech-to-noise ratio are highly correlated with intelligibility measures for Hearing in Noise Test (HINT) sentences, consonants and vowels. However, HINT sentence scores even in noise show ceiling effects that obscure the advantages of processors with eight or more channels. Moderate levels of noise that have only slight effects on other measures significantly affected CDT rate. CDT rates with three or four bands of spectral information were much lower than asymptotic rates, especially in the presence of noise.

Abstract
Drosophila slit is a secreted protein involved in midline patterning. Three vertebrate orthologs of the fly slit gene, Slit1, 2, and 3, have been isolated. Each displays overlapping, but distinct, patterns of expression in the developing vertebrate central nervous system, implying conservation of function. However, vertebrate Slit genes are also expressed in nonneuronal tissues where their cellular locations and functions are unknown. In this study, we characterized the cellular distribution and processing of mammalian Slit3 gene product, the least evolutionarily conserved of the vertebrate Slit genes, in kidney epithelial cells, using both cellular fractionation and immunolabeling. Slit3, but not Slit2, was predominantly localized within the mitochondria. This localization was confirmed using immunoelectron microscopy in cell lines and in mouse kidney proximal tubule cells. In confluent epithelial monolayers, Slit3 was also transported to the cell surface. However, we found no evidence of Slit3 proteolytic processing similar to that seen for Slit2. We demonstrated that Slit3 contains an NH(2)-terminal mitochondrial localization signal that can direct a reporter green fluorescent protein to the mitochondria. The equivalent region from Slit1 cannot elicit mitochondrial targeting. We conclude that Slit3 protein is targeted to and localized at two distinct sites within epithelial cells: the mitochondria, and then, in more confluent cells, the cell surface. Targeting to both locations is driven by specific NH(2)-terminal sequences. This is the first examination of Slit protein localization in nonneuronal cells, and this study implies that Slit3 has potentially unique functions not shared by other Slit proteins.

Abstract
Occupational Safety and Health Administration recordable upper-extremity musculoskeletal pains or disorders account for a significant number of work-related illnesses in the US workforce. Although the concept of musculoskeletal disorder prevention is appealing, little has been done to demonstrate the successful application and benefit of these programs. In 1995, an aircraft manufacturer established a unique risk-management program for new employees based on the CtdMAP individual risk assessment instrument. In 1998, a subgroup was prospectively studied for medical management on the basis of individual risk scores. Outcome measures were compared for the risk assessment group, the matched control group, and the total company. Employer-estimated savings in direct workers compensation costs were $2.42 million, and estimated indirect savings were over $13.5 million during the study.
