Abstract
Background Many analytical methods used in gut microbiome research focus on either single bacterial taxa or the whole microbiome, ignoring multi-bacteria relationships (microbial cliques). We present a novel analytical approach to identify multiple bacterial taxa within the gut microbiome of children at 9-11 years associated with prenatal Pb exposure. Methods Data came from a subset of participants (n=123) in the Programming Research in Obesity, Growth, Environment and Social Stressors (PROGRESS) cohort. Pb concentrations were measured in maternal whole blood from the second and third trimesters of pregnancy. Stool samples collected at 9-11 years old underwent metagenomic sequencing to assess the gut microbiome. Using a novel analytical approach, Microbial Co-occurrence Analysis (MiCA), we paired a machine-learning algorithm with randomization-based inference to first identify microbial cliques that were predictive of prenatal Pb exposure and then estimate the association between prenatal Pb exposure and microbial clique abundance. Results With second-trimester Pb exposure, we identified a 2-taxa microbial clique that included Bifidobacterium adolescentis and Ruminococcus callidus, and a 3-taxa clique that added Prevotella clara. Increasing second-trimester Pb exposure was associated with significantly increased odds of having the 2-taxa microbial clique below the 50th percentile relative abundance (OR=1.03,95%CI[1.01-1.05]). In an analysis of Pb concentration at or above vs. below the United States and Mexico guidelines for child Pb exposure, odds of the 2-taxa clique in low abundance were 3.36(95%CI[1.32-8.51]) and 6.11(95%CI[1.87-19.93]), respectively. Trends were similar with the 3-taxa clique but not statistically significant. Discussion Using a novel combination of machine-learning and causal-inference, MiCA identified a significant association between second-trimester Pb exposure and reduced abundance of a probiotic microbial clique within the gut microbiome in late childhood. Pb exposure levels at the guidelines for child Pb poisoning in the United States, and Mexico are not sufficient to protect against the potential loss of probiotic benefits.

Abstract
Perturbations in the gastrointestinal microbiome caused by antibiotics are a major risk factor for Clostridium difficile infection (CDI). Probiotics are often recommended to mitigate CDI symptoms; however, there exists only limited evidence showing probiotic efficacy for CDI. Here, we examined changes to the GI microbiota in a study population where probiotic treatment was associated with significantly reduced duration of CDI diarrhea. Subjects being treated with standard of care antibiotics for a primary episode of CDI were randomized to probiotic treatment or placebo for 4 weeks. Probiotic treatment consisted of a daily multi-strain capsule (Lactobacillus acidophilus NCFM, ATCC 700396; Lactobacillus paracasei Lpc-37, ATCC SD5275; Bifidobacterium lactis Bi-07, ATCC SC5220; Bifidobacterium lactis B1-04, ATCC SD5219) containing 1.7 x 1010 CFUs. Stool was collected and analyzed using 16S rRNA sequencing. Microbiome analysis revealed apparent taxonomic differences between treatments and timepoints. Subjects administered probiotics had reduced Verrucomicrobiaceae at week 8 compared to controls. Bacteroides were significantly reduced between weeks 0 to 4 in probiotic treated subjects. Ruminococcus (family Lachnospiraceae), tended to be more abundant at week 8 than week 4 within the placebo group and at week 8 than week 0 within the probiotic group. Similar to these results, previous studies have associated these taxa with probiotic use and with mitigation of CDI symptoms. Compositional prediction of microbial community function revealed that subjects in the placebo group had microbiomes enriched with the iron complex transport system, while probiotic treated subjects had microbiomes enriched with the antibiotic transport system. Results indicate that probiotic use may impact the microbiome function in the face of a CDI; yet, more sensitive methods with higher resolution are warranted to better elucidate the roles associated with these changes. Continuing studies are needed to better understand probiotic effects on microbiome structure and function and the resulting impacts on CDI.

Abstract
Fatty acid desaturases (FADS) play an important role in the formation of omega-6 and omega-3 highly unsaturated fatty acids (HUFAs). The composition of HUFAs in the human metabolome is important for membrane fluidity and for the modulation of essential physiological functions such as inflammation processes and brain development. Several recent studies reported significant associations of single nucleotide polymorphisms (SNPs) in the human FADS gene cluster with HUFA levels and composition. The presence of the minor allele correlated with a decrease of desaturase reaction products and an accumulation of substrates. We performed functional studies with two of the associated polymorphisms (rs3834458 and rs968567) and showed an influence of polymorphism rs968567 on FADS2 promoter activity by luciferase reporter gene assays. Electrophoretic mobility shift assays proved allele-dependent DNA-binding ability of at least two protein complexes to the region containing SNP rs968567. One of the proteins binding to this region in an allele-specific manner was shown to be the transcription factor ELK1 (a member of ETS domain transcription factor family). These results indicate that rs968567 influences FADS2 transcription and offer first insights into the modulation of complex regulation mechanisms of FADS2 gene transcription by SNPs.

Abstract
The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800-4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test if the rare evidence of fish and mollusc remains in the riverine shellmound led to (a) higher caries rates and (b) lower auditory exostosis frequency and (c) if the small size of the riverine shellmound translates into reduced demographic density and thus rarity of communicable infectious diseases. Of the three hypotheses, (a) was confirmed, (b) was rejected and (c) was partly rejected. Bioanthropological similarities between Moraes and coastal shellmounds include auditory exostoses with equally high frequencies; significantly more frequent osteoarthritis in upper than in lower limbs; cranial and dental morphological affinities and low frequencies of violent trauma. However, there are also important differences: Moraes subsisted on a much broader protein diet and consumed more cariogenic food, but showed a stature even shorter than coastal groups. Thus, despite the contact also suggested by treponematoses in both site types, there was enough time for the people at the riverine site to adapt to local conditions.

Abstract
Sambaquis are huge shellmounds built along almost the entire Brazilian coast between 8000 and 600 years ago. In the present article, 14 osteological markers from 89 individuals excavated at the Sambaqui Jabuticabeira II (2890+/-55/2186+/-60 BP) are analyzed in order to reconstruct the population's health status and way of life. The present palaeopathological findings (such as lower frequency of degenerative joint diseases in legs, as compared to arms, and the rarity of traumas) together with archaeological findings support the idea of nearby resource abundance and infrequent interpersonal competition. The presence of auditory exostoses mainly in males corroborates previous findings indicating the importance of marine resources. The low caries frequency and the high degrees of dental wear point to a diet poor in cariogenic food, and rich in abrasives such as sand, shell fragments and phytoliths. This suggests a broader diet, based on marine protein as well as plants, than previously thought. The etiology of cribra orbitalia could be explained by gastrointestinal parasites or other sources of physiological stress. These parasites, in turn, could have led to higher frequencies of infectious diseases, either by the debilitation of the immune system or by the direct contact with infectious agents. Despite the periods of illness various individuals experienced, the daily life among the builders of the Sambaqui Jabuticabeira II seems to have been relatively easy due to the abundance and predictability of resources and the paucity of violent traumas.

Abstract
Group differences in symptomatology and symptom perception of young women ageing between 18 and 32 years suffering from polycystic ovarian syndrome (PCOS) were tested according to cultural background and weight status. In detail 31 Austrian women, living in Carinthia, Austria, and 102 Brazilian women, living in São Paulo, Brazil, were enrolled in the present study. All participants suffered from diagnosed PCOS. The prevalence of hirsutism, infertility, menstrual disturbances and overweight/obesity and their individual impact on health related quality of life were analysed. Furthermore the impact of weight status (BMI) on symptom perception was tested. It turned out, that the Brazilian sample exhibited higher prevalence of PCOS symptoms and these symptoms had a more negative impact on quality of life. The only exception was body weight. Although significantly leaner, the Austrian women showed a higher Cronin score of body weight than their Brazilian counterparts. The results of the present study may indicate that in western industrialized societies the fear of overweight is much more prevalent than in a developing country such as Brazil and thus it has more influence on the quality of life than all the other symptoms.

Abstract
PCOS, the leading cause of anovulatory infertility that affects up to one fifth of the female population, is a complex chronic disease of genetic as well as environmental determination, but still unclear etiology. Besides of infertility, PCOS leads to menstrual dysfunctions, hirsutism and obesity--symptoms that are known to cause profound psychosocial distress. The present paper review the problematic of etiology and symptom expression of PCOS, which is not only a disease needing medical treatment but also a psychosocial problem for the affected women. PCOS may not only coinduced by psychosocial factors, the main symptoms of PCOS such as infertility, menstrual dysfunctions, hirsutism and obesity cause by themselves increased psychosocial stress.

Abstract
BACKGROUND During the last decades rhinosurgery largely developed up to endonasal accesses. Meanwhile many of the new techniques are established, so that the outcome of traditional extranasal methods should be compared with those of endonasal accesses, in order to estimate the status and for critical consideration. METHODS A retrospective analysis recorded the results of 236 patients, operated on primary frontal sinus disease 1985-1993. The records were consulted concerning inpatient treatment and outpatient aftercare during standardized paranasal sinus consulting hours. RESULTS During the follow-up period (3-10 years) 8% of the patients underwent resurgery. The lowest revision rate was found after using endonasal technique (5.9%), compared with osteoclastic methods (Ritter-Jansen, Riedel: 10.6%). The domain of osteoplastic operations with a revision rate of 9.4% were fractures, osteomas and mucoceles, because of an impossible endonasal access. In decision on osteoclastic procedures, the already osteoclastically operated site was of prime importance, especially since 1990. CONCLUSION Already during the early years endonasal techniques of paranasal sinus surgery showed better outcome than osteoclastic accesses. The analysis indicates that the change to endonasal functional paranasal sinus surgery is justified and should be kept up. The traditional methods still have their rare authorization in case of special indications, especially if an osteoclastic procedure has been carried out already.

Abstract
The aim of the present study was to assess the impact of genetic counseling in young women at risk to have Duchenne muscular dystrophy (DMD) children prior to childbearing. A total of 263 potential DMD carriers, who had had genetic counseling and were given different genetic risks, were included in this investigation. Their reproductive outcome and future plans as well as their requests for DNA tests (for carrier detection and prenatal diagnosis) were analyzed according to genetic risk magnitude, comprehension of genetic counseling is- sues, family and personal history, socio-educational level, and subjective opinion about selective abortion. We noted that genetic risk magnitude had no significant influence on reproductive plans or outcome nor on the request for additional DNA testing, even considering only those clients with good comprehension and retention of issues discussed during genetic counseling. On the other hand, counselees who had more than one affected or at least one deceased DMD case in their family understood genetic counseling significantly better, suggesting that "learning with life" has a stronger impact than genetic counseling.

Abstract
BACKGROUND In 1997, Benninger developed the Rhinosinusitis Disability Index (RSBI) for patients who suffered from chronic sinusitis. Its content related validity and construct related validity were established, as were its sensitivity and reliability. The aim of our study is to introduce a concept to measure quality of life in these patients according to circumstances prevalent in Germany. METHODS The questionnaire (Rhinusitis-Beeinträchtigungs-Index, RSBI) contains 30 questions that describe the 5 aspects of quality of life. Moreover we used a standardized data sheet to acquire further information about history and diagnostic results. Using this method it is possible to specificity more precisely the patients current complaints and condition. Evaluation is possible according to complex of questions as well as simple items. The influence of treatment on quality of life can be measured as the sum of the specific scores and is expressed comprehensively in the total score. The concept of the study includes a prospective inquiry as well as before and after surgical intervention. CONCLUSION A disadvantage of the American RSDI is that the clinical symptoms are not described in a detailed catalogue which allows the correlation of the clinical factors. Therefore we added a detailed questionnaire concerning the clinical symptoms and the individual treatment of the patient (RSBI). That permits comprehensive analysis of quality of life as it relates to different aspects of disease and different strategies in treatment.

Abstract
BACKGROUND Systemic absorption of iodinated contrast material occurs during endoscopic retrograde cholangiopancreatography (ERCP), the clinical significance of which has not yet been determined. METHODS Urinary iodine excretion was measured before and after coronary angiography (n = 20) and ERCP (n = 12). Thyroid hormone levels were determined before iodine load and after 6 and 24 weeks. RESULTS Before coronary angiography, iodine excretion was 101 +/- 38.3 micromol/mol creatinine and increased to 865. 10(5) +/- 721. 10(5) micromol/mol on the next day (p </= 0.001). After 6 weeks, it was still elevated (167 +/- 88.8 micromol/mol, p < 0.01). Before ERCP, iodine excretion was 115 +/- 60.3 micromol/mol and reached a peak of 5.3. 10(5) +/- 4.9. 10(5) micromol/mol (p < 0.001). Six weeks later, it had returned to baseline. Two patients in the coronary angiography group but none in the ERCP group had suppressed thyrotropin after 6 weeks. CONCLUSIONS The systemic iodine load during ERCP is approximately 0.6% of the iodine load during coronary angiography. Therefore routine measurement of thyroid hormones before ERCP is not recommended.

Abstract
The reproductive history of 177 male patients affected with Becker (BMD) (n=69), limb-girdle (LGMD) (n=54), and facioscapulohumeral (FSHMD) (n=54) muscular dystrophy (MD) was analysed according to severity of the disease (BMD>LGMD>FSHMD) and magnitude of recurrence risk (RR) (high for FSHMD, intermediate for BMD, and low for LGMD). Additionally, 62 male patients were interviewed on psychosocial issues, in order to disentangle the factors influencing reproductive decisions among patients affected with MD. Among male adults, significantly more FSHMD than LGMD or BMD patients were married and had children. Age specific reproductive outcome was 0.31-0.32 for BMD, 0.51-0.62 for LGMD, and 0.58-1.02 for FSHMD, reflecting the influence of the disease's severity. High RRs did not significantly diminish reproduction after genetic counselling or correlate with less prospective desire for children. Instead, early onset, severity of the disease, and past reproductive history were found to diminish reproductive outcome after genetic counselling, and prospective family planning was also found to be influenced by past reproductive history as well as by emotional/sexual dysfunction with the opposite sex.

Abstract
Adult male patients affected with Becker (BMD, N = 22), limb girdle (LGMD, N = 22) and facioscapulohumeral (FSHMD, N = 18) muscular dystrophy were interviewed to assess for the first time how the disease's severity and recurrence risk (RR) magnitude alter their social adjustment. BMD (X-linked recessive) is the severest form and confers an intermediate RR because all daughters will be carriers, LGMD (autosomal-recessive) is moderately severe with a low RR in the absence of consanguineous marriage, and FSHMD (autosomal-dominant) is clinically the mildest of these three forms of MD but with the highest RR, of 50%. Results of the semistructured questionnaire [WHO (1988): Psychiatric Disability Assessment Schedule] showed no significant difference between the three clinical groups, but more severely handicapped patients as well as patients belonging to lower socioeconomic levels from all clinical groups showed poorer social adjustment. Taken together, myopathic patients displayed intermediate social dysfunction compared to controls and schizophrenics studied by Jablensky [1988: WHO Psychiatric Disability Assessment Schedule]. Since the items of major dysfunction proportion among myopathic patients concern intimate relationships (70%), interest in working among those unemployed (67%), and social isolation (53%), emotional support and social and legal assistance should concentrate on these aspects. Interestingly, the results of this study also suggest that high RRs do not affect relationships to the opposite sex.

Abstract
BACKGROUND mRNA expression of healthy and malignant cells can be compared to each other by employing the "differential display" (DD) technique. Most studies describe sequence analysis of differentially expressed fragments after reamplification by a second round of PCR and subsequent molecular cloning to gain a sufficient amount of DNA for sequencing. The aim of this study was to show whether a sufficient amount of differentially expressed mRNA of squamous cell carcinoma cells of the head and neck region can be generated by PCR alone without cloning steps. MATERIAL AND METHODS mRNA isolated from cultivated keratinocytes and squamous cell carcinoma cells was reverse transcribed into cDNA which was amplified with PCR. Differentially expressed fragments detected after gel electrophoresis were isolated from the gel and reamplified in a second PCR. The resulting cDNA amounts of the second PCR were suitable for cloning but not for direct sequencing. A third round of PCR with the undiluted final product of the second PCR as template regularly failed. Dilutions of the second PCR products between 1:10 and 1:10(10) were prepared. The third round of PCR was carried out with these various template concentrations. RESULTS A sufficient amount of differentially expressed fragments for sequencing procedures resulted when dilutions of the second PCR products ranging from 1:10(2) to 1:10(7) were used as templates in the third round of PCR. CONCLUSION Modifications of PCR parameters provide high DNA copy numbers of differentially expressed mRNA fragments from squamous cell carcinoma cells of the upper aerodigestive tract in amounts that are needed for sequence analysis. This may make it possible to avoid labor-intensive cloning procedures requiring high safety standards.

Abstract
We had previously reported that patients affected with BMD have a significantly reduced reproductive performance (f = 0.12) as compared to male LGMD patients of similar age and physical impairment (f = 0.98). In the present study parameters such as the socio-economic level, as well as psychosocial, intellectual, and psychiatric functionings could not explain the low fitness of BMD patients. The effect of genetic counseling, a greater difficulty in coping with the disease, and relating to women and/or a potential malfunction of reproductive physiology are discussed as possible causes.

Abstract
There are some indications that Becker muscular dystrophy (BMD) might be related to mental disorders and mental retardation (MR). To investigate this question, we made a standardized psychiatric and intellectual level assessment of 22 BMD patients in comparison with 22 limb-girdle muscular dystrophy (LGMD) patients. There were not significant differences between the two groups. Twelve patients (54.5%) in each group received at least one lifetime psychiatric diagnosis, the most frequent being depressive disorders. The intelligence quotient means for BMD was 85.9 and 87.8 for LGMD. There was one case of mild MR among BMD patients and two cases among LGMD patients.

Abstract
A questionnaire about the interest in and demand for preclinical diagnosis for facioscapulohumeral muscular dystrophy (FSH) was sent to 46 patients. Most stated that they would have liked to have known their diagnosis earlier in order to seek more efficient help, to avoid strenuous activities, to prepare themselves emotionally, or to choose an appropriate profession. Similar arguments were used to explain their interest in preclinical diagnosis for their children. Most patients also favoured prenatal diagnosis although only two stated they would abort a pregnancy in the case of an affected fetus. Genetic counselling had apparently little influence on family planning. According to this study, FSH does not seem to reduce reproductive performance in our population.

Abstract
249 episodes of Streptococcus bacteraemia in hospitalized patients were evaluated for both clinical and microbiological features. Specification of the isolates demonstrated that infective endocarditis was predominantly associated with Streptococcus sanguis and Streptococcus bovis whereas Streptococcus pyogenes and Streptococcus milleri were the most common cause of local and/or systemic infections. In vitro-susceptibility tests towards 9 selected antibiotics proved that beta-lactam antibiotics are potent compounds for the treatment of Streptococcus sp. with the exception of enterococci; that ampicillin turned out to be highly effective against enterococci; and that vancomycin may be regarded as a potent alternative in the treatment of streptococcal infections.

Abstract
A total of 161 unrelated Duchenne (DMD) and Becker muscular dystrophy (BMD) patients were screened for deletions in the brain promoter region of the dystrophin gene. Southern blot analysis using a probe for the brain promoter detected a deletion in this region in only one of the DMD families, in a patient with normal intelligence. This deletion also included the promoter of the muscle-type dystrophin and the exons encoding the actin-binding and part of the spectrin-like domains. Our data suggest that deletions in the brain promoter region are rare in DMD and are compatible with normal intelligence.

Abstract
The aetiology of juvenile plantar dermatosis (JPD) is probably multifactorial. Atopy, frictional factors and the frequent alternation between a hot and wet microclimate and a dry one seem to favour the dermatosis. An allergic contact dermatitis does not only involve a difficult differential diagnosis; it can also cause secondary deterioration of existing JPD. For these reasons, an attempt is made in this paper to specify the situations in which patch tests are indicated.

Abstract
This paper presents light- and electron-microscopic findings in a case of ‘fibrous hamartoma of infancy’ localized on both soles of an 18-month-old boy. The examinations show immature fibroblastic proliferation and progressive evolution to mature and dense fibrocol-lagenous trabeculae. Myo-fibroblastic features are frequently found. However, a review of the literature reveals that myo-fibroblasts are indeed found in all cases of fibromatous and scarring processes and even in normal fibrous tissue.

Abstract
Three children afflicted with ataxia-telangiectasia are briefly presented; the main characteristics and etiopathogenic factors are summarized. Cutaneous signs enumerate: telangiectasias on sun-exposed areas; pigmentary disturbances; atopic dermatitis; microbial, viral and mycotic infections, and progeria-like dystrophy. In these three children, the high number of café-au-lait spots and hypochromic macules appeared at first suggestive of neurofibromatosis or tuberous sclerosis.

Abstract
Necrobiotic xanthogranuloma represents a very peculiar dermatosis with distinctive microscopic features. It is associated with paraproteinemia and quite often with myeloma : it is a good marker of medullary dysfunction or degeneration. The pathogenesis of cutaneous granulomas remains highly speculative: distorted interaction of histiocytes and lymphocytes-plasmocytes and influence of immune complexes. So far, chlorambucil appears as the most interesting drug.
