Abstract
BACKGROUND A programme based on health education has been developed to prevent foot dermatoses (FD) in patients with work-related skin diseases (WRSD). OBJECTIVE To evaluate the effectiveness of the programme in a prospective cohort study (OCCUPES). METHODS Six and 12 months after completing the programme, follow-up questionnaires were sent to 231 patients with WRSD and FD. Assessments included occupational footwear and foot care, self-reported disease course, and health-related quality of life. RESULTS Response to follow-ups was >70%. Wearing functional socks and changing footwear and socks during one work shift increased (all p < 0.001). Complaints about occupational footwear decreased, including sweating and exposure to moisture/wetness. More than 60% reported improved FD while quality of life significantly increased. After 12 months, all foot symptoms were less frequent, including itch (p = 0.009), pain when walking (p = 0.005), pain in rest (p = 0.015) and smell (p = 0.001). The programme received very good ratings by the participants. CONCLUSIONS The intervention was effective in improving occupational footwear, foot care and preventive behaviour. It resulted in a reduced burden of FD and should be implemented in the general care of patients with WRSD.

Abstract
BACKGROUND Programmes for prevention of hand dermatoses in patients with work-related skin diseases (WRSD) are well established. Similar interventions for foot dermatoses (FD) are widely missing. OBJECTIVE To evaluate the effectiveness of a programme for prevention of FD based on health education in patients with WRSD while investigating the impact and possible causative factors of FD. METHODS In a prospective cohort study (OCCUPES), 231 patients with WRSD and FD participating in the programme were recruited. The skin was examined and questionnaires were completed, including assessment of footwear, FD severity, symptoms and health-related quality of life. RESULTS The baseline and some early results are presented. A work-related causation of FD was likely in 60 patients (26.0%) with irritant contact dermatitis being the most frequent diagnosis. Work-related FD were associated with male sex (p = 0.012), sweating in footwear (p = 0.004) and wearing of safety footwear (p = 0.013). FD were often long-lasting with a high degree of work-absenteeism, quality of life impairment, itch and pain, particularly in work-related FD. CONCLUSIONS Interventions are needed to reduce the burden of FD in patients with WRSD. The programme addresses current shortcomings in prevention of FD. A long-term evaluation of its effectiveness follows.

Abstract
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a volatile-metal-like character. Here, we present further experimental data on adsorption studies of Fl on silicon oxide and gold surfaces, accounting for the inhomogeneous nature of the surface, as it was used in the experiment and analyzed as part of the reported studies. We confirm that Fl is highly volatile and the least reactive member of group 14. Our experimental observations suggest that Fl exhibits lower reactivity towards Au than the volatile metal Hg, but higher reactivity than the noble gas Rn.

Abstract
Nihonium (Nh, element 113) and flerovium (Fl, element 114) are the first superheavy elements in which the 7p shell is occupied. High volatility and inertness were predicted for Fl due to the strong relativistic stabilization of the closed 7p 1/2 sub-shell, which originates from a large spin-orbit splitting between the 7p 1/2 and 7p 3/2 orbitals. One unpaired electron in the outermost 7p 1/2 sub-shell in Nh is expected to give rise to a higher chemical reactivity. Theoretical predictions of Nh reactivity are discussed, along with results of the first experimental attempts to study Nh chemistry in the gas phase. The experimental observations verify a higher chemical reactivity of Nh atoms compared to its neighbor Fl and call for the development of advanced setups. First tests of a newly developed detection device miniCOMPACT with highly reactive Fr isotopes assure that effective chemical studies of Nh are within reach.

Abstract
Background In Germany, work-related skin diseases are predominant within the spectrum of reported occupational diseases. Metal workers are among the high-risk professions. Offering effective prevention programs to affected patients is of utmost importance to avoid deterioration of the disease and job loss. We conducted a 1-year follow-up in patients who participated in a multidisciplinary, complex outpatient prevention program representing a standard procedure of patient care by the respective statutory accident insurance. Methods The multi-component prevention program consists of multiprofessional individual patient counseling, a structured skin protection seminar in a group, as well as workplace visits and on-site counseling in terms of appropriate skin protection (e.g. gloves). An observational study with a 1-year follow-up and four measurements (T1-T4, longitudinal pre/post-test design) including dermatological examinations and standardized written questionnaires was conducted between 2013 and 2016 to assess changes over time regarding job loss and disease severity. Results Data from 94 patients (87 male, mean age: 45.4 years) were included in the analysis. One year after the skin protection seminar (T4), 83 patients (88.3%) remained in their original professional metalworking activity and four patients (4.3%) had given up their profession because of their skin disease. At baseline (T1), irritant contact dermatitis of the hands was the most frequent diagnosis (80.7%). Methods for self-reported disease severity showed good correlation with the clinical gold standard at T1 and T2 (dermatological examination with the Osnabrück Hand Eczema Severity Index / OHSI), and a significant decrease of the self-reported disease severity was found over time from T1 to T4 (p < 0.001). Further results indicate an improved self-perceived disease control and an overall satisfaction with the prevention program. Conclusions The results of this observational study demonstrate that the comprehensive prevention program positively influences the course of work-related skin diseases, increases the possibility to continue working in a “high-risk” profession and improves the disease management of metal workers. In the long term, the prevention program may lead to cost savings by preventing high therapy costs or professional retraining.

Abstract
BACKGROUND Occupational skin diseases (OSDs) are frequent in professions with exposure to skin hazards. Thus, a health educational intervention for apprentices of high-risk professions was conducted. It was the aim of this study to gain insight into possible effects of this intervention. METHODS A one-time skin protection seminar was conducted in 140 apprentices of health-related and non-health-related professions [trained cohort (TC)]. In addition, 134 apprentices of the same occupations were monitored [untrained cohort (UTC)]. The OSD-specific knowledge and the skin condition of the hands were assessed at baseline (T0), after the seminar (T1), and after 6 (T2) and 12 months (T3). RESULTS The OSD-specific knowledge increased in all cohorts from T0 to T3, but we found a significantly higher knowledge in the TC at T2 (p < 0.001, t = 3.6, df = 196, 95% confidence interval = 0.9, 3.3) and T3 (p < 0.001, t = 3.8, df = 196, 95% confidence interval = 1.0, 3.2) compared to the UTC. Our results indicated a better skin condition of the hands in the TC of the health-related professions but not in the non-health-related professions. CONCLUSION The study indicates that an educational intervention may positively influence the disease-specific knowledge and the prevalence of OSD in apprentices. However, definite conclusions cannot be drawn because of the heterogeneous study cohorts and the study design. Future research should aim at tailoring primary prevention to specific target groups, e.g., in view of the duration and frequency of skin protection education, different professions, and gender-specific prevention approaches.

Abstract
Two short-lived isotopes ^{221}U and ^{222}U were produced as evaporation residues in the fusion reaction ^{50}Ti+^{176}Yb at the gas-filled recoil separator TASCA. An α decay with an energy of E_{α}=9.31(5) MeV and half-life T_{1/2}=4.7(7) μs was attributed to ^{222}U. The new isotope ^{221}U was identified in α-decay chains starting with E_{α}=9.71(5) MeV and T_{1/2}=0.66(14) μs leading to known daughters. Synthesis and detection of these unstable heavy nuclei and their descendants were achieved thanks to a fast data readout system. The evolution of the N=126 shell closure and its influence on the stability of uranium isotopes are discussed within the framework of α-decay reduced width.

Abstract
BACKGROUND Docetaxel is a widely used cytotoxic agent. This study evaluates the impact of docetaxel toxicities on patient's health-related quality of life (QoL). PATIENTS AND METHODS We conducted a multicenter, prospective, non-interventional trial, in which the QoL was assessed using the EORTC QLQ-C30 questionnaires at baseline and every 4 weeks up to 40 weeks in patients receiving a docetaxel-based chemotherapy for metastatic disease. Treatment-related adverse events were correlated with the corresponding QoL scores. Uni- and multivariate analyses were applied. RESULTS From January 2008 to June 2011, a total of 2659 patients were included. The majority of patients (48.1%) had prostate cancer, followed by breast (17.1%) and non-small-cell-lung cancer (15.8%). Patients received a median of 5 docetaxel cycles with the median dose of 75 mg/m(2). The presence of grade 3/4 diarrhea showed the strongest effect on global health status/QoL average scores (50.91 versus 33.06), followed by vomiting (50.91 versus 35.17), dyspnea (50.94 versus 35.81), mucositis/stomatitis (50.88 versus 36.41), nausea (50.91 versus 36.68), infection (50.90 versus 37.14), fatigue (50.90 versus 43.82) and anemia (50.91 versus 41.03), P < 0.05 for all comparisons. Grade 3/4 leukopenia/neutropenia, alopecia, constipation, neurotoxicity and nail disorders had no significant impact on the global health status/QoL or other items. CONCLUSION In this large non-interventional trial, docetaxel-associated grade 3 or 4 toxicities were shown to have a strong detrimental effect on patient's QoL. Notably, diarrhea and vomiting had the strongest negative impact on QoL measures. This has to be kept in mind while making therapeutic decisions and providing optimized supportive treatment measures. CLINICAL TRIALS NUMBER This study was registered at Deutsches Krebsstudienregister (DKSR, primary registry in the WHO Registry Network) with the ID 527.

Abstract
OBJECTIVE To analyze treatment outcomes and the association between treatment effects and health-related quality of life (HRQoL) for incontinent children, and their parents. SUBJECTS AND METHODS Health-related quality of life in 70 consecutively treated children, and their parents, was assessed with the Pediatric Incontinence Questionnaire and the WHO-Quality-Of-Life-BREF questionnaire. This was assessed before and after three months of standardized treatment. RESULTS In 44.3% of children, symptoms decreased by 50-89%. After three months of treatment, the HRQoL of children improved significantly. Children with bladder and bowel dysfunction had a significantly lower HRQoL than children with isolated nocturnal enuresis, daytime urinary incontinence or fecal incontinence. Parental HRQoL did not change significantly within three months of treatment. Parents showed a significantly lower mean in the 'psychological' domain of the WHO-QoL-BREF questionnaire compared to norms. CONCLUSION Children with different subtypes of incontinence can be treated effectively within three months of therapy. After three months, significant improvements of HRQoL were shown. Parents showed no general reduction in their quality of life (QoL). Specific aspects of parental QoL were impaired, but did not improve during the treatment of their children.

Abstract
We imaged surfaces of freshly grown flat pearl nacre (Haliotis tuberculata) in different stages of growth in seawater using an atomic force microscope (AFM). Characteristic mineral phases of nacre, such as aragonitic stacks of coins, as well as the associated organic sheets, could be detected. Apart from imaging, the acquisition of force volumes on freshly grown organic surface areas on flat pearl nacre was conducted with the AFM. The evaluation of the force volumes with the Hertz-Sneddon model resulted in Young's moduli in the MPa range. The presented values are considerably smaller than values previously determined from macroscopic tensile tests. This might reflect the anisotropy of the organic nacre layers.

Abstract
The superheavy element with atomic number Z=117 was produced as an evaporation residue in the (48)Ca+(249)Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their α-decay products was studied using a detection setup that allowed measuring decays of single atomic nuclei with half-lives between sub-μs and a few days. Two decay chains comprising seven α decays and a spontaneous fission each were identified and are assigned to the isotope (294)117 and its decay products. A hitherto unknown α-decay branch in (270)Db (Z = 105) was observed, which populated the new isotope (266)Lr (Z = 103). The identification of the long-lived (T(1/2) = 1.0(-0.4)(+1.9) h) α-emitter (270)Db marks an important step towards the observation of even more long-lived nuclei of superheavy elements located on an "island of stability."

Abstract
The fusion-evaporation reaction 244Pu(48Ca,3-4n){288,289}114 was studied at the new gas-filled recoil separator TASCA. Thirteen correlated decay chains were observed and assigned to the production and decay of {288,289}114. At a compound nucleus excitation energy of E{*}=39.8-43.9 MeV, the 4n evaporation channel cross section was 9.8{-3.1}{+3.9} pb. At E^{*}=36.1-39.5 MeV, that of the 3n evaporation channel was 8.0{-4.5}{+7.4} pb. In one of the 3n evaporation channel decay chains, a previously unobserved α branch in 281Ds was observed (probability to be of random origin from background: 0.1%). This α decay populated the new nucleus 277Hs, which decayed by spontaneous fission after a lifetime of 4.5 ms.

Abstract
OBJECTIVE Albright hereditary osteodystrophy (AHO) and Pseudohypoparathyroidism type Ia (PHPIa) are caused by an inherited deficiency of Gsalpha, encoded by the GNAS gene. Apart from an exclusive first exon, Gsalpha shares part of the transcribed regions with NESP55, Exon A/B and XLalphas, whose gene products utilize alternative promoter regions of this complex gene locus. However, it is not known, whether the deficiency of all gene products contributes to the AHO and PHPIa phenotype or if they are even causative for some specific symptoms. In these cases, mutations affecting selectively GNAS exon 1, coding only for Gsalpha, would lead to a different phenotype than mutations affecting the common exons 2-13. METHODS Clinical and molecular genetic analysis of a patient with features of AHO and review of exclusive exon 1 mutations of GNAS. RESULTS We detected a novel heterozygous 1 bp deletion of a guanine in codon 31 in exon 1 of the GNAS gene leading to a frame shift and premature termination of Gsalpha. The female patient demonstrated a fully expressed AHO and PHPIa phenotype and a decreased Gsalpha protein activity of 62% compared to the wild type. Mutations in exon 1 are almost exclusively disruptive and lead to an AHO phenotype that does not show obvious differences from those provoked by missense or nonsense mutations in exon 2-13. CONCLUSION Disruptive mutations in exon 1 indicate that exclusive deficiency of Gsalpha is sufficient for the expression of an AHO phenotype, which cannot be compensated by alternative products of GNAS.

Abstract
In a genome-wide screen using differential methylation hybridization (DMH), we have identified a CpG island within the 5' region and untranslated first exon of the secretory granule neuroendocrine protein 1 gene (SGNE1/7B2) that showed hypermethylation in medulloblastomas compared to fetal cerebellum. Bisulfite sequencing and combined bisulfite restriction assay were performed to confirm the methylation status of this CpG island in primary medulloblastomas and medulloblastoma cell lines. Hypermethylation was detected in 16/23 (70%) biopsies and 7/8 (87%) medulloblastoma cell lines, but not in non-neoplastic fetal (n=8) cerebellum. Expression of SGNE1 was investigated by semi-quantitative competitive reverse transcription-polymerase chain reaction and found to be significantly downregulated or absent in all, but one primary medulloblastomas and all cell lines compared to fetal cerebellum. After treatment of medulloblastoma cell lines with 5-aza-2'-deoxycytidine, transcription of SGNE1 was restored. No mutation was found in the coding region of SGNE1 by single-strand conformation polymorphism analysis. Reintroduction of SGNE1 into the medulloblastoma cell line D283Med led to a significant growth suppression and reduced colony formation. In summary, we have identified SGNE1 as a novel epigenetically silenced gene in medulloblastomas. Its frequent inactivation, as well as its inhibitory effect on tumor cell proliferation and focus formation strongly argues for a significant role in medulloblastoma development.

Abstract
Although the atypical antipsychotic olanzapine is increasingly being used in child and adolescent psychiatry, reports of olanzapine overdose in this young population are scarce. We report on two cases of adolescents who attempted suicide with an overdose of olanzapine: (1) A 14-year-old female ingested 275 mg olanzapine, which produced the highest reported nonlethal serum level (1503 ng/mL) and caused somnolence, agitation (acutely), and extrapyramidal symptoms (EPS; after 54 hours) but no major clinical complications. The serum olanzapine level dropped to 129 ng/mL within 48 hours; and (2) a 17-year-old male ingested 400 mg olanzapine, the highest reported nonlethal dose of olanzapine in adolescents, which produced respiratory suppression requiring intubation and mechanical ventilation; he recovered after 3 days. Based on clinical monitoring and postmortem data, the 2 patients survived the ingestion of high doses of olanzapine. We also provide a review of the literature, encompassing all reported cases of olanzapine overdose in children and adolescents and discuss symptoms, diagnosis, and treatment options, based on pharmacokinetic and pharmacodynamic considerations.

Abstract
Lamins, members of the family of intermediate filaments, form a supportive nucleoskeletal structure underlying the nuclear envelope and can also form intranuclear structures. Mutations within the A-type lamin gene cause a variety of degenerative diseases which are collectively referred to as laminopathies. At the molecular level, laminopathies have been shown to be linked to a discontinuous localization pattern of A-type lamins, with some laminopathies containing nuclear lamin A aggregates. Since nuclear aggregate formation could lead to the mislocalization of proteins interacting with A-type lamins, we set out to examine the effects of FLAG-lamin A N195K and R386K protein aggregate formation on the subnuclear distribution of the retinoblastoma protein (pRb) and the sterol responsive element binding protein 1a (SREBP1a) after coexpression as GFP-fusion proteins in HeLa cells. We observed strong recruitment of both proteins into nuclear aggregates. Nuclear aggregate recruitment of the NPC component nucleoporin NUP153 was also observed and found to be dependent on the N-terminus. That these effects were specific was implied by the fact that a number of other coexpressed karyophilic GFP-fusion proteins, such as the nucleoporin NUP98 and kanadaptin, did not coaggregate with FLAG-lamin A N195K or R386K. Immunofluorescence analysis further indicated that the precursor form of lamin A, pre-lamin A, could be found in intranuclear aggregates. Our results imply that redistribution into lamin A-/pre-lamin A-containing aggregates of proteins such as pRb and SREBP1a could represent a key aspect underlying the molecular pathogenesis of certain laminopathies.

Abstract
RpoS and RpoN are two alternative sigma factors typically associated with general stress responses in bacteria. To date, there has been no experimental evidence that RpoS and RpoN can directly control the expression of one another. Herein, using a combined strategy of gene disruption and genetic complementation targeting rpoN and rpoS in Borrelia burgdorferi strain 297, we describe a regulatory network for B. burgdorferi. In this network, RpoN controls the expression of RpoS, which, in turn, governs the expression of two important membrane lipoproteins, outer surface protein C and decorin-binding protein A, and likely other proteins of B. burgdorferi. Our findings provide a foundation for elucidating further key regulatory networks that potentially impact many aspects of B. burgdorferi's parasitic strategy, host range, and virulence expression.

Abstract
Burkholderia cepacia AC1100 uses the chlorinated aromatic compound 2, 4,5-trichlorophenoxyacetic acid (2,4,5-T) as a sole source of carbon and energy. The enzyme which converts the first intermediate in the pathway, 2,4,5-trichlorophenol, to 5-chlorohydroquinone has been purified and consists of two subunits of 58 and 22 kDa, encoded by the tftC and tftD genes (48). A degenerate primer was designed from the N terminus of the 58-kDa polypeptide and used to isolate a clone containing the tftC and tftD genes from a genomic library of AC1100. The derived amino acid sequences of tftC and tftD show significant homology to the two-component monooxygenases HadA of Burkholderia pickettii, HpaBC of Escherichia coli, and HpaAH of Klebsiella pneumonia. Expression of the tftC and tftD genes appeared to be induced when they were grown in the presence of 2,4,5-T, as shown by RNA slot blot and primer extension analyses. Three sets of cloned tft genes were used as probes to explore the genomic organization of the pathway. Pulsed-field gel electrophoresis analyses of whole chromosomes of B. cepacia AC1100 demonstrated that the genome is comprised of five replicons of 4.0, 2.7, 0.53, 0.34, and 0.15 Mbp, designated I to V, respectively. The tft genes are located on the smaller replicons: the tftAB cluster is on replicon IV, tftEFGH is on replicon III, and copies of the tftC and the tftCD operons are found on both replicons III and IV. When cells were grown in the absence of 2,4,5-T, the genes were lost at high frequency by chromosomal deletions and rearrangements to produce 2,4,5-T-negative mutants. In one mutant, the tftA and tftB genes translocated from one replicon to another, with the concomitant loss of tftEFGH and one copy of tftCD.

These elements are not highly related to other insertion sequences identified in AC1100 or other B. cepacia isolates. Based on their structures and the sequences of the inverted terminal repeats and the putative transposase protein, the insertion elements (IS elements) are similar to IST2 of Thiobacillus ferrooxidans and several related elements. All the IS elements that have been identified in this strain are found in multiple copies (10 to 40), and they have high-level promoter activity capable of stimulating transcription from a distance up to 500 bp from a target gene. Strain AC1100 was originally isolated after prolonged selection for the ability to utilize the herbicide 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as a sole carbon source. Three IS elements are located near the first gene of the 2,4,5-T catabolic pathway, tftA. IS1490 inserted 110 bp upstream of tftA and created a fusion promoter responsible for constitutive transcription of the gene. Our results confirm the hypothesis that IS elements play a central role in transcription of 2,4,5-T genes and likely have stimulated rapid evolution of the metabolic pathway.

Abstract
Many microorganisms in nature have evolved new genes which encode catabolic enzymes specific for chlorinated aromatic substrates, allowing them to utilize these compounds as sole sources of carbon and energy. An understanding of the evolutionary mechanisms involved in the acquisition of such genes may facilitate the development of microorganisms with enhanced capabilities of degrading highly chlorinated recalcitrant compounds. A number of studies have been based on microorganisms isolated from the environment which utilize simple chlorinated substrates. In our laboratory, a selective technique was used to isolate microorganisms capable of degrading highly chlorinated compounds, such as 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), as sole sources of carbon and energy. This article summarizes the genetic and biochemical information obtained regarding the pathway of degradation, the mechanism of recruitment of new genes, and the organization of the degradative genes. In addition, we discuss the potential practical application of such microorganisms in the environment.

Abstract
A prospective study was performed to investigate the role of the endogenous fibrinolytic system and platelet function for the occurrence of reocclusion after successful recanalization of chronic coronary occlusions. At control coronary angiography 8 +/- 2 weeks after recanalization, reocclusion was found in 10 (21%) of 47 patients. After correction for angiographic and clinical confounding factors, endogenous concentrations of tissue plasminogen activator (TPA) were lower in patients with reocclusion than in patients without. In contrast, plasma levels of plasminogen activator inhibitor-1 and alpha 2-antiplasmin were similar in the two groups. The mean platelet volume was significantly higher in patients with reocclusion than in patients without. In addition, agonist-induced platelet aggregation in platelet-rich plasma was enhanced in the patients with reocclusion. Decreased endogenous plasma TPA concentrations and enhanced platelet reactivity may contribute to the occurrence of reocclusion after primarily successful coronary artery recanalization.

Abstract
PURPOSE We compare the bacteriological and clinical efficacy of rufloxacin and ciprofloxacin in patients with acute uncomplicated pyelonephritis. MATERIALS AND METHODS A total of 110 outpatients was enrolled in a randomized, double-blind multicenter study and treated for 10 days with 200 mg. rufloxacin daily (after a loading dose of 400 mg. on day 1) or 500 mg. ciprofloxacin twice daily. Bacteriological and clinical efficacy was based on the accumulated outcomes assessed at the end of treatment, and at 2 and 4 to 6 weeks. RESULTS The bacteriological and clinical success rates of rufloxacin and ciprofloxacin were comparable: 55.6% versus 58.8% and 74% versus 71%, respectively (95% confidence interval -28% to +22% and -20% to +25%, respectively). Both study medications were well tolerated. CONCLUSIONS Rufloxacin once daily is a good alternative in the outpatient treatment of acute uncomplicated pyelonephritis.

Abstract
The in vitro fidelity of reverse transcriptase from human immunodeficiency virus type I (HIV-1 RT) upon copying an RNA template was measured using the phi Xam 16 reversion assay. A phi X174 sequence harboring the amber 16 codon was cloned into a transcription vector. RNA obtained from transcription by bacteriophage T7 RNA polymerase was used as a template for RNA-directed DNA synthesis by HIV-1 RT. An imbalance of dNTP concentrations during the reverse transcription step served to distinguish between errors that arose from the transcription step and errors from reverse transcription. The frequency of dGTP.U mismatches was determined to be 1/360, while dGTP.rA mismatches formed at a rate of 1/4600. These are 20-fold and sevenfold higher, respectively, than the error rates determined for the same sequence with a DNA template. Due to a high background of errors in the RNA template originating from the transcription step only upper limits for the frequency of three other mismatches can be given. The data indicate that the reverse transcription step of the HIV-1 replication cycle contributes significantly to the generation of mutant viruses.

Abstract
Typical in MEA IIb is a combination of medullary carcinoma of the thyroid gland and a pheochromocytoma with neurocutaneous and skeletal anomalies and a hyperplasia of the sympathetic nervous system of the GI tract with megacolon. Two patients of a family with MEA II are described. The family history reveals 1) an autosomal inheritance with high penetrance, 2) a changing pattern of anomalies in different generations, 3) no marfanoid traits as typical in MEA IIb, 4) only males affected by megacolon. This may be an uncommon variation or an additional type: IIc. Further investigation is required.

Abstract
The electrophysiological, antiarrhythmic and haemodynamic profile of a new isoquinolinedione derivative, 2,2'-[iminobis(trimethylene)]-di(4,4-dimethyl-1,3-(2H,4H)-isoqu inolinedione) hydrochloride (AR-03 Cl) was evaluated using dog models relevant to conditions in humans. In 16 animals dose-related effects on intercardiac conduction, ventricular refractoriness and on haemodynamic parameters were determined. In another 7 dogs antiarrhythmic actions of AR-03 Cl on delayed reperfusion arrhythmias following release of coronary artery occlusion after 2 h of obstruction were investigated. The results show: AR-03 Cl causes a significant prolongation in conduction through all parts of the conducting system. The AH-interval, HV-interval and QRS-duration are significantly lengthened. Ventricular repolarization is only slightly changed. There are no significant changes in heart rate, systolic and diastolic aortic pressure up to doses of 2 mg/kg b.w. However, left ventricular (dp/dtmax) and cardiac output are significantly reduced, and left ventricular enddiastolic pressure is increased. In acute myocardial necrosis delayed reperfusion arrhythmias are almost completely abolished, the effective dose is lower than that required with any other antiarrhythmic drug investigated so far in this particular experimental set-up. Further experimental and clinical testing of the new compound seems to be promising because of its strong dose-related antiarrhythmic potency. However, there is a need for further analysis of potential haemodynamic side effects of the new compound to establish the clinical significance of negative inotropic actions at therapeutic doses.

Abstract
The explorative laparoscopy has changed the attitude to certain contraindications. Concretions are of importance for the disposition of the penumoperitoneum and for the inspection. Their view is variable and is of importance only after larger intraabdominal interventions. In 218 laparoscopies performed we found 55 times concretions, of them important ones in three fourths. In 90% additional diagnostic points of view could be got.
