Abstract
BACKGROUND AND PURPOSE Malformations of the brain stem are uncommon. We present MR imaging and diffusion tensor imaging (DTI) features of 6 patients with pontine tegmental cap dysplasia, characterized by ventral pontine hypoplasia and a dorsal "bump," and speculate on potential mechanisms by which it forms. MATERIALS AND METHODS Birth and developmental records of 6 patients were reviewed. We reviewed MR imaging studies of all patients and DTIs of patient 3. Potential developmental causes were evaluated. RESULTS All patients were born uneventfully after normal pregnancies except patient 6 (in utero growth retardation). They presented with multiple cranial neuropathies and evidence of cerebellar dysfunction. Variable hypotonia and motor dysfunction were present. Imaging revealed ventral pontine hypoplasia and mild cerebellar vermian hypoplasia, in addition to an unusual rounded to beaklike "bump" on the dorsal surface of the pons, extending into the fourth ventricle. Color fractional anisotropy maps showed the bump to consist of a bundle of axons directed horizontally (left-right). The bump appeared, on morphologic images, to be continuous with the middle cerebellar peduncles (MCPs), which were slightly diminished in size compared with those in healthy infants. Analysis of the DTI was, however, inconclusive regarding the connections of these axons. The decussation of the MCPs, transverse pontine fibers, and longitudinal brain stem axonal pathways was also abnormal. CONCLUSIONS Our data suggest that the dorsal transverse axonal band in these disorders results from abnormal axonal pathfinding, abnormal neuronal migration, or a combination of the 2 processes.

Abstract
The inheritance of most forms of epilepsy is usually considered to be multifactorial, although a number of single gene causes are known. Most previous studies of epilepsy genetics have implicated ion channel genes or ligand receptors. In a previous study of children with adverse effects of prenatal exposure to antiepileptic drugs, we noted an increased frequency of the methylene tetrahydrofolate reductase (MTHFR) 677C>T polymorphism in the mothers. To investigate this further, a new cohort of women with epilepsy has been identified from maternity hospital records and genotyped for polymorphisms in MTHFR, serine hydroxymethyl transferase (SHMT1), methionine synthase (MTR) and methionine synthase reductase (MTRR). Healthy blood donors were genotyped as controls. The frequency of the MTHFR 677TT genotype was significantly higher in women with idiopathic generalised epilepsy than in healthy controls (p=0.012, OR 2.26, 95%CI 1.13-4.51). No association was detected for the other polymorphisms tested. The MTHFR 677C>T polymorphism may be a susceptibility factor for epilepsy, and its higher frequency in women with epilepsy may contribute to the increased risk of malformation in children of women with epilepsy.

Abstract
Currently, any dentist in the UK who is HIV-seropositive must stop treating patients. This is despite the fact that hepatitis B-infected dentists with a low viral load can continue to practise, and the fact that HIV is 100 times less infectious than hepatitis B. Dentists are obliged to treat HIV-positive patients, but are obliged not to treat any patients if they themselves are HIV-positive. Furthermore, prospective dental students are now screened for hepatitis B and C and HIV, and are not allowed to enrol on Bachelor of Dental Surgery degrees if they are infectious carriers of these diseases. This paper will argue that: (i) the current restriction on HIV-positive dentists is unethical, and unfair; (ii) dentists are more likely to contract HIV from patients than vice versa, and this is not reflected by the current system; (iii) the screening of dental students for HIV is also unethical; (iv) the fact that dentists can continue to practise despite hepatitis B infection, but infected prospective students are denied matriculation, is unethical; and (v) that the current Department of Health protocols, as well as being intrinsically unfair, have further unethical effects, such as the waste of valuable resources on 'lookback' exercises and the even more damaging loss of present and future dentists. Regulation in this area seems to have been driven by institutional fear of public fear of infection, rather than any scientific evidence or ethical reasoning.

Abstract
Concern has been expressed about the applicability of the findings of the International Subarachnoid Aneurysm Trial (ISAT) with respect to the relative effects on outcome of coiling and clipping. It has been suggested that the findings of the National Study of Subarachnoid Haemorrhage may have greater relevance for neurosurgical practice. The objective of this paper was to interpret the findings of these two studies in the context of differences in their study populations, design, execution and analysis. Because of differences in design and analysis, the findings of the two studies are not directly comparable. The ISAT analysed all randomized patients by intention-to-treat, including some who did not undergo a repair, and obtained the primary outcome for 99% of participants. The National Study only analysed participants who underwent clipping or coiling, according to the method of repair, and obtained the primary outcome for 91% of participants. Time to repair was also considered differently in the two studies. The comparison between coiling and clipping was susceptible to confounding in the National Study, but not in the ISAT. The two study populations differed to some extent, but inspection of these differences does not support the view that coiling was applied inappropriately in the National Study. Therefore, there are many reasons why the two studies estimated different sizes of effect. The possibility that there were real, systematic differences in practice between the ISAT and the National Study cannot be ruled out, but such explanations must be seen in the context of other explanations relating to chance, differences in design or analysis, or confounding.

Abstract
To establish a valid animal model of the effects of olfactory stimuli on anxiety, a series of experiments was conducted using rats in an open-field test. Throughout, effects of lavender oil were compared with the effects of chlordiazepoxide (CDP), as a reference anxiolytic with well-known effects on open-field behaviour. Rats were exposed to lavender oil (0.1-1.0 ml) for 30 min (Experiment 1) or 1h (Experiment 2) prior to open-field test and in the open field or injected with CDP (10 mg/kg i.p.). CDP had predicted effects on behaviour, and the higher doses of lavender oil had some effects on behaviour similar to those of CDP. In Experiment 3, various combinations of pre-exposure times and amounts of lavender oil were used. With sufficient exposure time and quantity of lavender the same effects were obtained as in Experiment 2. Experiment 4 demonstrated that these behavioural effects of lavender could be obtained following pre-exposure, even if no oil was present in the open-field test. In Experiments 2-4, lavender oil increased immobility. Together, these experiments suggest that lavender oil does have anxiolytic effects in the open field, but that a sedative effect can also occur at the highest doses.

Abstract
A multilocus sequence typing (MLST) scheme was devised for Aspergillus fumigatus. The system involved sequencing seven gene fragments and was applied to a panel of 100 isolates of A. fumigatus from diverse sources. Thirty different sequence types were found among the 100 isolates, and 93% of the isolates differed from the other isolates by only one allele sequence, forming a single clonal cluster as indicated by the eBURST algorithm. The discriminatory power of the MLST method was only 0.93. These results strongly indicate that A. fumigatus is a species of a relatively recent origin, with low levels of sequence dissimilarity. Typing methods based on variable numbers of tandem repeats offer higher levels of strain discrimination. Mating type data for the 100 isolates showed that 71 isolates were type MAT1-2 and 29 isolates were MAT1-1.

Abstract
Vagus nerve stimulation (VNS) is now available as a treatment for epilepsy and treatment-resistant depression. The vagus nerve plays a central role in satiety and short-term regulation of food intake and research suggests a relationship between VNS and weight loss. The underlying mechanisms of this relationship are unknown. The purpose of the current study was to determine whether acute cervical VNS might temporarily alter food cravings. Thirty-three participants were recruited for three groups; depression VNS, depression non-VNS, and healthy controls. Participants viewed 22 computerized images of foods twice in one session and completed ratings for food cravings after each image. The VNS participants' devices were turned on for one viewing of an image and off for the other (randomized order). Participants were blind to VNS condition (on versus off). Acute VNS device activation was associated with a significant change in cravings-ratings for sweet foods. A significant proportion of variability in VNS-related changes in cravings was accounted for by patients' clinical VNS device settings, acute level of depression, and body mass. Further studies are warranted addressing how acute or chronic VNS might modify eating behavior and weight.

Abstract
We have adapted our established Alu PCR assay for proviral DNA and PCR for total cellular DNA to a real-time PCR format and applied these to human immunodeficiency virus (HIV)-positive specimens collected for routine determination of the plasma viral load (pVL). In a cohort of five patients, measurements of integrated viral load (iVL) and cell-associated viral load (cVL) in CD4(+) cells isolated by a single positive selection step were not indicative of HIV DNA levels in the circulation, and further analysis was performed on peripheral blood mononuclear cells (PBMC). In a cohort of 46 samples total cVL was quantitated in most samples, but iVL could be quantitated in only 47.8%, since in 26% iVL was undetectable and in 21.7% the results were invalid due to high levels of unintegrated HIV DNA. There was no correlation of cVL or iVL with pVL, CD4 count, or duration of successful antiretroviral treatment. Out of 26 patients with undetectable pVL, 4 patients failed therapy within the subsequent 12 months and had higher than average iVL, but this was not the case for cVL. Among nine patients with long-term undetectable pVL, no consistent decline in cVL or iVL was seen with time, and changes in cVL and iVL within a patient could be concordant or discordant. These results show that cVL and iVL can be coordinately measured in PBMC from clinical samples but do not correlate with pVL, CD4 counts, or length of suppressive antiretroviral therapy. Interestingly, a high iVL (but not a high cVL) in patients with undetectable pVL was associated with subsequent treatment failure.

Abstract
In infections following orthopaedic surgery, isolated staphylococci are reported to be methicillin resistant (MRSA) in up to 50% of cases. Linezolid, the first in a new class of antibiotics, has excellent efficacy against gram positive organisms that are resistant to other therapies and is 100% orally bioavailable. We report early results of its use for the treatment of resistant infections in orthopaedic practice. Infections were characterised according to the UK Nosocomial Infections National Surveillance Service classification of surgical infections as superficial, deep or organ/space. Osteomyelitis, joint sepsis and deep infection involving orthopaedic implants were included into the final category. Outcome was recorded as clinical, microbiological and blood parameter cure or fail. Over the 12-month study period, 54 patients received linezolid therapy, 41% of these had significant co-morbidity that might affect their ability to fight infection. Sixty-seven percent of infections were in association with implanted metal work. The majority of patients were treated with vancomycin for a short period before linezolid was used as oral 'switch' therapy for longer-term administration, allowing early discharge in all cases. MRSA was isolated in 87% of the patients treated. The mean length of linezolid therapy was 39 days (2-151). Clinical success was achieved in 90% of patients overall. Though there were no life-threatening complications, adverse event rates were significantly higher than those recorded in the literature, with 19% of patients needing to cease therapy. Linezolid offers an alternative to traditional treatments for resistant infections and can facilitate early discharge. Patients need to be monitored closely, particularly where long-term therapy is planned.

Abstract
The Millennium Development Goals (MGD) represent a commitment of 189 member states that adopted them during the Millennium Summit in September 2000. This UN General Assembly recognized that gender equality and women's empowerment are both central to achieving sustainable development by means of combating poverty, hunger and disease. Neither reproductive nor sexual health was explicitly articulated in the original MDGs and indicators-a critical omission, as globally women are more disadvantaged than men. However, a clear link exists between all of the MDGs and the reproductive and sexual health of women, who cannot contribute to sustainable development, unless their right to health is met through improved access. The FIGO 2006 World Report on Women's Health addresses many issues critical to the success of the MDGs, with a focus on how partnerships have become a crucial vehicle to improve access to health for women.

Abstract
During an intense survey of natural woodlands around Lake Hodges (33°N, 117°W) in June 2001, symptoms typical of root and collar rot caused by Phytophthora spp. were observed on 27% of 474 coast live oaks (Quercus agrifolia Nee.) and on none of 86 Engelmann oaks (Q. engelmannii Greene), in spite of complete spatial intermixing of the two species. Symptoms on coast live oaks included viscous exudates emerging through intact bark matched by underbark dark lesions with irregular margins. Lesions were delineated by a dark line and present on the root collar or the buttress of symptomatic trees. Crowns of trees with lesions ranged from completely healthy to declining or dead. All symptomatic trees were in proximity of the lake or streams. Phytophthora cinnamomi Rands was isolated from four trees in three distinct sites by plating tissues from lesion margins on PARP selective medium and from four soil samples by using standard pear baiting and plating lesions from pear tissue onto PARP. Identification of the isolates was obtained from microscopic observations and direct sequencing of the internal transcribed spacer region of the rDNA (Genbank Accession Nos. AY302148, MC2 and AY302149, MC3). P. citricola Sawada was also isolated once. Pathogenicity tests were completed to compare the susceptibility of the two species of oaks growing in the Lake Hodges region with P. cinnamomi. Two P. cinnamomi isolates from Lake Hodges (MC2, ATCC MYA-3711; MC3) and one isolate from an avocado orchard in San Diego County (MC6) were used to inoculate separately 10 5-year-old trees each of Q. agrifolia and Q. engelmannii grown in 5-gallon containers. Inoculations were performed in two lath-house experiments during February and September 2002 by placing an 8-mm diameter V8-agar plug from the margin of a P. cinnamomi colony underbark and sealing the wound with Parafilm and grafting wax. Lesion lengths were measured 2 months after inoculation, and the presence of the pathogen confirmed by reisolation on PARP. Mean average, maximum, and minimum temperatures were 14, 19, and 9°C and 21, 24, and 18°C for the February and September inoculations, respectively. The February inoculation resulted in small lesions only on Q. agrifolia (26 ± 15 mm, SD). The September inoculation resulted in 135 ± 68 mm (SD) lesions on Q. agrifolia and 49 ± 35 mm (SD) lesions on Q. engelmannii. Controls did not show any lesions. The length of lesions was significantly different between the two hosts (P < 0.0001) and significant differences were observed among the three isolates (P = 0.0018). Although Q. agrifolia is a known host for P. cinnamomi in California (2,3), to our knowledge, this is the first report of widespread infestation of P. cinnamomi in natural oak woodlands in the western United States. Survey and inoculation results indicated Q. engelmannii to be less susceptible to infection. Inoculation results confirm previous research that cold temperatures are unfavorable to this pathogen and isolates differed in pathogenicity toward Q. agrifolia. Decline of oaks infected by P. cinnamomi was observed only in conjunction with other factors, in particular with the presence of the oak twig girdler, Agrilus angelicus Horn., an insect favored by stress conditions such as drought. Similar effects have been reported for Mediterranean oaks infected by the same pathogen (1). References: (1) C. M. Brasier. Nature 360:539, 1992. (2) P. A. Miller. Western Shade Tree Conf.
