Abstract
Gastrointestinal involvement in systemic sclerosis can be severe, reaching the critical point of chronic intestinal pseudo-obstruction, secondary to major disorders of small bowel motility. It is associated with some clinical and biological characteristics, in particular the positivity of anti-fibrillarin/U3RNP antibodies. Chronic intestinal pseudo-obstruction (CIPO) is complicated by a small intestinal bacterial overgrowth that requires cyclic antibiotic therapy. CIPO leads to a reduction of the food intake, due to painful symptoms, nausea and vomiting caused by meals, and ultimately to severe malnutrition. Meal splitting is often transiently effective and patients require exogenous nutritional support, mostly parenteral. Systemic sclerosis is not an obstacle to initiation and long-term continuation of parenteral nutrition and central venous catheter implantation is not associated with an increased risk of cutaneous or infectious complications. However, continuation of long-term parenteral nutrition requires monitoring in an expert nutrition center in order to adapt nutritional volumes and intakes and to limit potentially fatal cardiac and hepatobiliary complications. In addition to nutrition, prokinetic treatments, whose side effects must be known, can be associated. Invasive procedures, whose risk-benefit ratio must be carefully assessed, can also be used to treat symptoms exclusively.

Abstract
Three-dimensional (3D) full-field measurements provide a comprehensive and accurate validation of finite element (FE) models. For the validation, the result of the model and measurements are compared based on two respective point-sets and this requires the point-sets to be registered in one coordinate system. Point-set registration is a non-convex optimization problem that has widely been solved by the ordinary iterative closest point algorithm. However, this approach necessitates a good initialization without which it easily returns a local optimum, i.e. an erroneous registration. The globally optimal iterative closest point (Go-ICP) algorithm has overcome this drawback and forms the basis for the presented open-source tool that can be used for the validation of FE models using 3D full-field measurements. The capability of the tool is demonstrated using an application example from the field of biomechanics. Methodological problems that arise in real-world data and the respective implemented solution approaches are discussed.

Abstract
INTRODUCTION Miliary brain metastases are a rare form of brain metastatic lesions. CASE REPORT We report the case of a 58-year-old patient with lung adenocarcinoma and an EGFR mutation, who had metastatic lesions in the bones, pleura and pericardia at the time of diagnosis. The patient was treated with tyrosine kinase inhibitor. A few months later, he presented with progressive neuropsychiatric symptoms, which were attributed to miliary brain metastases based on the radiological pattern (micronodules, some of which were calcified) and the elimination of alternative possible diagnoses. Despite tumour stability in the thorax and metastatic sites other than the brain, his neurological condition deteriorated, even after cerebral radiotherapy, leading to his death eight months after the diagnosis of lung cancer. CONCLUSION Miliary brain metastases are a rare form of brain metastases with unusual clinical presentation. The diagnosis is based on the radiological pattern of cerebral miliary dissemination, with sometimes calcified tumor nodules. Despite its rarity, several cases have been reported in lung adenocarcinoma in the presence of EGFR mutations.

Abstract
The Li-Fraumeni syndrome (LFS) is an inherited form of cancer, affecting children and young adults, and characterized by a wide spectrum of tumors, including soft-tissue and bone sarcomas, brain tumours, adenocortical tumours and premenopausal breast cancers. In most of the families, LFS results from germline mutations of the tumor suppressor TP53 gene encoding a transcriptional factor able to regulate cell cycle and apoptosis when DNA damage occurs. Recently, germline mutations of hCHK2 encoding a kinase, regulating cell cycle via Cdc25C and TP53, were identified in affected families. The LFS working group recommendations are the following: (i) positive testing (screening for a germline TP53 mutation in a patient with a tumor) can be offered both to children and adults in the context of genetic counseling associated to psychological support, to confirm the diagnosis of LFS on a molecular basis. This will allow to offer to the patient a regular clinical review in order to avoid a delay to the diagnosis of another tumor; (ii) the 3 indications for positive testing are: a proband with a tumor belonging to the narrow LFS spectrum and developed before age 36 and, at least, first- or second-degree relative with a LFS spectrum tumor, before age 46, or a patient with multiple primary tumors, 2 of which belonging to the narrow LFS spectrum, the first being developed before 36 or a child with an adenocortical tumour; (iii) presymptomatic testing must be restricted to adults; (iv) the young age of onset of the LFS tumors the prognosis of some tumors, the impossibility to ensure an efficient early detection and the risk for mutation carriers to develop multiple primary tumors justify that prenatal diagnosis might be considered in affected families.

Abstract
Spinal and bulbar muscular atrophy (SBMA) is a motor neuron disease caused by the expansion of a polyglutamine tract within the androgen receptor. This disease is unusual among the polyglutamine diseases in that it involves lower motor and sensory neurons, with relative sparing of other brain structures. We describe the development of transgenic mice, created with a truncated, highly expanded androgen receptor driven by the neurofilament light chain promoter, which develop many of the motor symptoms of SBMA. In addition, transgenic mice created with the prion protein promoter develop widespread neurologic disease, reminiscent of juvenile forms of other polyglutamine diseases. Thus, in these experiments, the distribution of neurologic symptoms depends on the expression level and pattern of the promoter used, rather than on specific characteristics of androgen receptor metabolism or function. The transgenic mice described here develop neuronal intranuclear inclusions (NIIs), a hallmark of SBMA and the other polyglutamine diseases. We have shown these inclusions to be ubiquitinated and to sequester molecular chaperones, components of the 26S proteasome and the transcriptional activator CREB-binding protein. Apart from the presence of NIIs, evidence of neuropathology or neurogenic muscle atrophy was absent, suggesting that the neurologic phenotypes observed in these mice were the result of neuronal dysfunction rather than neuronal degeneration. These mice will provide a useful resource for characterizing specific aspects of motor neuron dysfunction, and for testing therapeutic strategies for this and other polyglutamine diseases.

Abstract
Arginine vasopressin (AVP) regulates biological processes by binding to G protein-coupled receptors. In Swiss 3T3 fibroblasts, expressing the V(1a) subtype of vasopressin receptors, AVP mobilizes calcium from intracellular stores. In proliferating cells, the AVP-induced increase in intracellular calcium concentration ([Ca(2+)](i)) was mediated by G proteins of the G(q) family, which are insensitive to pertussis toxin (PTX) pretreatment of the cells. In quiescent cells, the AVP-induced increase in [Ca(2+)](i) was partially PTX-sensitive, suggesting an involvement of G(i) proteins. We confirmed this by photoaffinity labeling of G proteins in Swiss 3T3 cell membranes activated by AVP. In Swiss 3T3 cells arrested in the G(0)/G(1) phase of the cell cycle, the AVP-induced increase in [Ca(2+)](i) was also partially PTX-sensitive but was PTX-insensitive in cells arrested in other phases of the cell cycles. The blocking effect of PTX pretreatment in G(0)/G(1) cells was mimicked by microinjection of antisense oligonucleotides suppressing the expression of the Galpha(i3) subunits. These results were confirmed by microinjection of antibodies directed against the C terminus of G protein alpha-subunits. The data presented indicate that in Swiss 3T3 fibroblasts synchronized in the G(0)/G(1) phase of the cell cycle the V(1a) receptor couples to G(q/11) and G(i3) to activate the phospholipase C-beta, leading to release of intracellular calcium.

Abstract
Amyotrophic lateral sclerosis (ALS) denotes a heterogeneous group of neurodegenerative disorders affecting upper and lower motor neurons. ALS4 is a juvenile-onset, autosomal dominant form of ALS that is characterized by slow progression, distal limb weakness and amyotrophy, and pyramidal signs associated with severe loss of motor neurons in the brain and spinal cord. The ALS4 locus was recently mapped by linkage analysis to a large genetic interval on chromosome 9q34. By undertaking extensive genetic linkage analysis, we have significantly refined the ALS4 locus to a critical interval of less than 3 cM, flanked by D9S149 and D9S1198. Previous physical mapping in this region has indicated that this critical interval spans approximately 500 kb. Seventeen putative transcripts have been localized within this interval including 7 characterized genes, 2 partially characterized genes, and 8 "anonymous" expressed sequence tags . These are therefore positional candidate genes for the ALS4 locus. We have also undertaken mutation analysis and genetic mapping to investigate and exclude candidate genes, including RING3L/ORFX and RALGDS, from a pathogenic role in ALS4.

Abstract
The family history of cancer in children treated for a solid malignant tumour in the Paediatric Oncology Department at Institute Gustave-Roussy, has been investigated. In order to determine the role of germline p53 mutations in genetic predisposition to childhood cancer, germline p53 mutations were sought in individuals with at least one relative (first- or second-degree relative or first cousin) affected by any cancer before 46 years of age, or affected by multiple cancers. Screening for germline p53 mutation was possible in 268 index cases among individuals fulfilling selection criteria. Seventeen (6.3%) mutations were identified, of which 13 were inherited and four were de novo. Using maximum likelihood methods that incorporate retrospective family data and correct for ascertainment bias, the lifetime risk of cancer for mutation carriers was estimated to be 73% for males and nearly 100% for females with a high risk of breast cancer accounting for the difference. The risk of cancer associated with such mutations is very high and no evidence of low penetrance mutation was found. These mutations are frequently inherited but de novo mutations are not rare.

Abstract
X-linked Charcot-Marie-Tooth disease is caused by mutations in the gene for the gap junction protein connexin32. This protein is expressed in peripheral nerve and present in noncompacted myelin, where it likely forms channels around and across the myelin sheath. Studies in cell culture and in transgenic mice show that connexin32 mutations can cause a loss of channel function or a gain of toxic effects on myelinating Schwann cells or both, with resulting peripheral nerve degeneration.

Abstract
X-linked Charcot-Marie-Tooth disease (CMTX) is an inherited demyelinating neuropathy caused by mutations in the gene encoding the gap junction protein connexin32 (Cx32). Despite the identification of over 160 different mutations in the Cx32 coding sequence, it is not known whether the mutations cause the disease manifestations through a loss of Cx32 function or through toxic effects on peripheral nerve. We created transgenic mice with a frameshift mutation at codon 175 (175fs), identified in a large CMTX pedigree. Light microscopic examination of the peripheral nerves from adult transgenic animals showed no pathological features. Western blotting did not show transgenic Cx32 protein in any of the 26 lines, although expression of transgenic messenger RNA was detected by reverse-transcriptase polymerase chain reaction and by ribonuclease protection assay. Our findings indicate that the 175fs mutation results in a loss of Cx32 function, without additional toxic effects.

Abstract
Kennedy's disease is an X-linked form of motor neuron disease caused by an expanded polyglutamine repeat in the androgen receptor. While the expansion mutation causes some loss of transcriptional activity by the androgen receptor, the predominant effect of expansion is probably a toxic gain of function, similar to the mechanism of other polyglutamine expansion diseases. Features of the neurodegenerative phenotype of Kennedy's disease have now been reproduced in transgenic animals and neuronal cell culture. Nuclear inclusions of mutant androgen receptor protein are found in these model systems and in autopsy samples from patients with Kennedy's disease.

Abstract
Mutations in the gene encoding the gap junction protein connexin32 (Cx32; beta 1) cause the X-linked form of Charcot-Marie-Tooth disease (CMTX), a common form of inherited demyelinating neuropathy. Cx32 is localized to the paranodes and incisures of myelinating Schwann cells, and probably participates in the formation of gap junctions at these locations, thereby allowing the diffusion of ions and small molecules directly across the myelin sheath. In transfected cells different CMTX mutations have different effects on the ability of the mutant protein to form functional gap junctions; some mutant proteins cannot be detected within the cell, other mutant proteins accumulate within the cell but do not reach the cell membrane, while other mutants reach the cell membrane and some of these form functional gap junctions. In transgenic mice two mutants, R142W and 175 frameshift, have similar effects on protein trafficking as in transfected cells: the R142W mutant protein remains in the perinuclear region and does not reach the paranodes or incisures, and the 175 frameshift protein cannot be detected. Thus, different CMTX mutations have different effects on Cx32 protein, and these differences may help to explain the phenotypic differences seen in CMTX kindreds.

Abstract
Almost all patients with amyotrophic lateral sclerosis (ALS) experience symptoms of nocturnal hypoventilation during the course of the illness. These symptoms can develop years before death and may severely affect quality of life. Non-invasive intermittent home mechanical ventilation (HMV) via mask is a possible palliative measure for these symptoms, which is not often used in Germany. We report on our experience with HMV in 24 patients with ALS. Our data show a good palliative effect in 17 of 24 treated patients. Severe complications did not occur. The mean ventilation time at present is 14 months. Available options and their consequences need to be discussed in detail with patients and relatives before HMV is initiated.

Abstract
In a review of the chest X-rays and medical records of 597 cases of culture- or biopsy-proven pulmonary tuberculosis (PTB; age range 1.5-72 years), seen over a period of 6 years (1991-97), 26 patients had radiographic patterns unusual for PTB. These patterns were mass-like densities simulating neoplasms, chronic lower lobe airspace opacities without adenopathy, mediastinal adenopathy without parenchymal airspace opacities and bronchopleural fistula without other radiographic abnormalities. The most common of these unusual radiographic patterns was mass-like densities, most of which were initially and mistakenly diagnosed as neoplasms. These masses, seen in 11 adult patients, form the basis of this report. Two children aged 1.5 and 2 years also had tuberculous mass densities initially diagnosed as neurogenic tumour and round pneumonia, respectively. They have been excluded from the present series, and form the subject of another report. The masses were lower lobe predominant and were not usually associated with fibro-productive satellite lesions or with calcification or cavitation. In view of the recent resurgence of PTB and the importance of chest X-rays in its diagnosis and management, this rare radiographic pattern needs to be emphasized.

Abstract
Dopamine transporter imaging was performed in 18 patients with sporadic amyotrophic lateral sclerosis (ALS) and 11 age matched controls with [I-123] IPT (N-(3-iodopropen-2-yl)-2beta-carbomethoxy-3beta(4-chlorophen yl)-tropane), a new cocaine analogue that selectively binds to the dopamine transporter located on dopaminergic nerve terminals. Image analysis showed that striatal IPT binding was moderately but significantly reduced in the ALS group compared with controls (p<0.01). The reduction of IPT binding was similar for patients with bulbar onset compared with those with limb onset. There was no correlation between values for uptake of striatal IPT and the age of the patients or the duration of the disease. These data indicate that nigrostriatal dopaminergic neurons are subclinically affected in a subset of patients with sporadic ALS.

Abstract
X-chromosomal recessive bulbospinal neuronopathy (X-BNS, Kennedy's disease) is an important differential diagnosis of amyotrophic lateral sclerosis. We present the data of ten own patients along with a review of the literature on this uncommon disease which is caused by an expanded CAG-repeat in the androgen receptor gene. This mutation probably affects the transcription regulating activity of the androgen receptor in neurons. Signs and symptoms of X-BSN can be derived from partial insensitivity for androgens and a mixed, mainly motor neuronopathy. The clinical diagnosis is based on: 1. lower motor neuron weakness of bulbar and proximal limb muscles with onset in the third to fifth decade, 2. cramps and pronounced fasciculations, particularly of facial muscles, 3. postural tremor, 4. diminished or absent sensory action potentials inspite of only minor sensory impairment, 5. gynecomastia, and 6. infertility, diabetes mellitus and hyperlipoproteinemia in a minority of cases. Unlike amyotrophic lateral sclerosis, disease progression is slow with barely shortened life expectancy, which should be stressed in patient counselling. Causal treatment is as yet unavailable but several aspects of palliative medicine should be considered.

Abstract
Background: Schistosomiasis is second only to Malaria in its prevalence in the tropics. The mode of transmission of this disease is unknown to many travelers, whereas other travelers consciously choose to ignore recommendations offered by travel clinics. Methods: We present a descriptive analysis of 22 patients who presented with S. haematobium (SH) infection to two travel clinics in Israel during 1993 and 1994. Results: All 22 patients (mean age 24.2 yrs) apparently acquired SH in lake Malawi. The group contained seven couples, which indicates a very high attack rate. Three of the cases were asymptomatic, thereby causing a diagnostic delay of up to 52 weeks. Diagnosis was established in 18 cases by finding eggs in the urine, and in eight cases, by serology. Conclusion: All cases of SH diagnosed at two medical centers in Israel in 1993 and 1994 were acquired in Lake Malawi. A few of the cases were totally asymptomatic, which raises the question of routine screening. Travel clinics should warn travelers to the Lake Malawi region of this specific hazard.

Abstract
We undertook a family study of children treated at the Institute Gustave-Roussy in France to investigate a familial aggregation of cancer in the families of children with non-Hodgkin's lymphoma (NHL). We obtained family dat for 284 children with NHL. Using the Standardized Incidence Ratio, we compared the observed and expected number of families with at least one proband relative affected by cancer at a young age (before 46 years). We found a small but non-significant excess of all tumors in first-degree relatives (SIR = 1.3, 95% CI = 0.7-2.3) explained by a small but non-significant excess of hematological malignancies (SIR = 1.5, 95% CI = 0.2-5.5), particularly Hodgkin's disease and leukemia, and of osteosarcoma (SIR = 7.5, 95% CI = 0.1-41.4). This is probably a lower bound of the SIR, because the expected number of families was estimated from cancer incidence in France between 1978 and 1982, whereas most cancers occurred before this period. Other tumors were not in excess in first-degree relatives.

Abstract
We present 5 cases of Schistosoma hematobium infestation recently acquired during travel to Lake Malawi. Clinical presentations ranged from asymptomatic to prolonged pneumonitis. The laboratory diagnosis in suspected cases rests on both searching for ova in the urine, and on serological tests which may become positive before the appearance of ova. One of the returning travelers also acquired trichinosis and another amebiasis. Because of the sharp increase in those traveling to the tropics, especially young people, physicians should be aware of the possibilities of their acquiring schistosomiasis.

Abstract
This study examines the workshift changes in lung function among 99 recycling workers, and correlates these findings with measurements of total dust and endotoxins. Exposure to organic dust caused a fall in FEV1 over the workshift, and this was significantly associated with the exposure to organic dust. No significant association was found between endotoxin exposure and lung function decrements. This lack of association could be due to the low concentrations of endotoxins to which the workers were exposed, as no workers were exposed to more than 100 ng/m3.

Abstract
There continues to be an increased interest in developing community-based services for children and adolescents as an alternative to inpatient care. However, there has been much more talk than action in creating such alternatives. This paper describes the success of a crisis stabilization program for children and adolescents in a community mental health center which historically over-utilized the State psychiatric facility for youth. The Crisis Stabilization Program consists of three components: (1) a two-person crisis team, (2) a four-person on-call team for after hours crises, and (3) funds which the crisis team utilized to broker for a wider array of community-based services.

Abstract
Almost no experimental analysis of blushing has been done since Darwin's observations in 1872. Forty-eight college women watched a videotape intended to elicit blushing, and a videotape not intended to elicit blushing, but elicit physiological responses. A subject was alone, or with one or four persons present. Blushing, which was measured directly with a photoplethysmograph probe on the cheek, was greater during the blushing than nonblushing stimulation. Blushing increased as audience size increased from one to four, but not from zero to one. Audience size and kind of stimulation interacted statistically. Similar results were obtained with ear coloration, cheek temperature, and skin conductance responses, although confidence levels were lower. Cheek coloration and temperature were significantly correlated during nonblushing stimulation, and the zero and one audience conditions, but not during the four audience condition, when blushing was greatest. These results may be placed within the context of emotional effects of audience size generally, including stuttering and speech disturbance, disruption of learning, and self-reported tension.

Abstract
Little work on the psychophysiology of blushing has been done since Darwin's 1872 observations. Facial vascular and temperature changes have been largely ignored in psychophysiology. We had 16 female and 16 male undergraduate volunteers watch a videotape intended to produce blushing (the individual's singing recorded the previous day), and a videotape not intended to produce blushing, but elicit physiological responses for comparison (a segment from Hitchcock's movie Psycho). Four people were present as a subject watched these video segments. Cheek and ear coloration, measured photoplethysmographically, cheek temperature, and finger skin conductance responses were significantly greater during stimulation intended to elicit blushing than during comparison stimulation. Gender interacted statistically with kind of stimulation only in cheek temperature. Only video segments of the subject's face that coincided with maximal cheek coloration during stimulation intended to produce blushing were judged reliably as blushing, and then more often in females than in males.

Abstract
REM sleep is associated with the production of complex imagery sequences. Yet research is divided as to whether different brain regions are more or less coordinated in their functioning at this time. Some research suggests that there may occur a functional disconnection of the left and right cerebral hemispheres during REM sleep which is similar to the disconnection syndrome seen after corpus callosotomy. Other research suggests that an increase in interhemispheric coordination occurs. On the assumption that hemispheric coordination is reflected in the EEG coherence measure, we explored differences in interhemispheric coherence recorded in six left- and six right-handed normal subjects during periods of wakefulness, stage REM, stage 2, and stage 3/4 sleep. Strong evidence was found that mean EEG coherence values are larger during sleep than during waking and that they are approximately equal for the different stages of sleep. Frontal electrode placements demonstrated a slightly different pattern of coherence than central, parietal, or occipital placements. Furthermore, coherence values were larger for left-handed subjects over the occipital region during wakefulness, stage 2, and stage REM sleep, but not during stage 3/4 sleep. Coherence was not different for male and female subjects. These findings oppose the interpretation that a functional disconnection of hemispheres occurs during REM sleep and favor the interpretation that sleep in general is a state of heightened cortical coordination. Moreover, greater interhemispheric coherence over occipital brain regions in left-handed subjects suggests possible differences in the cognitive processes of these subjects during waking and dreaming states.
