Abstract
Chronic hepatitis C virus (HCV) infection can cause severe liver cirrhosis, for which liver transplantation is the only therapy. To prevent organ rejection, transplanted patients are treated with immunosuppressive agents. We describe two transplanted patients treated with tacrolimus who were simultaneously treated with direct-acting antivirals (DAAs) for their chronic HCV infection. No pharmacokinetic drug-drug interactions (DDIs) were expected between tacrolimus and the selected DAAs. However, in both patients, tacrolimus plasma concentrations decreased during HCV treatment. We hypothesise that decreased plasma concentrations were not caused by a DDI but were an indirect result of the clearance of the HCV infection. During chronic HCV infection, pro-inflammatory cytokines may inhibit cytochrome P450 (CYP) enzymes, which are primarily responsible for tacrolimus metabolism. If this is true, then with clearance of the virus the activity of these enzymes will normalise and tacrolimus metabolism will increase. These changes were clinically relevant because the tacrolimus dosage needed to be adjusted. Therefore, physicians should be aware that CYP substrates with narrow therapeutic ranges might require dose adaption during HCV therapy with DAAs.

Abstract
Burns from domestic irons are potentially preventable injuries which can result in significant morbidity. Several studies have reported these injuries in children but there are no reports to date in adults. Epidemiology, management and outcome of these injuries is described, and possible preventative strategies are discussed. We present a retrospective case note review of 50 adult and paediatric patients with electric iron burns. Cases were identified from data collected for a national burns database. Information regarding demographics, burn characteristics, treatment and long term outcome was gathered from the medical records. 42 children and 8 adults sustained a burn from an iron during the 4-year study period. The majority of paediatric patients were under 4 years of age. Most burns were small (< 1% TBSA) but despite this 30 (60%) patients were admitted to hospital and 13 (26%) required at least one surgical procedure. In children, most burns occurred at home and were commonly due to pulling the flex or knocking the iron from its surface. In adults, 50% of injuries were associated with epilepsy. Burns from domestic irons are relatively common and cause significant morbidity despite their small size. A bimodal presentation is seen with injuries occurring either before the age of 4 years or during adulthood, when they are typically associated with an underlying medical condition. Education campaigns and design features such as a retractable cord may further reduce the incidence of this type of burn.

Abstract
Autoantibodies in hepatitis C virus-infected patients may indicate autoimmune hepatitis or other immune-mediated diseases. This may impact safety and efficacy of interferon-based therapy of chronic hepatitis C. We investigated the association between a positive test result for a variety of autoantibodies and the initiation and efficacy of therapy for chronic hepatitis C. We analysed an observational cohort of 24 306 patients for an association between autoantibodies and treatment outcome. 8241 patients were tested simultaneously for antinuclear antibodies (ANA), liver kidney microsomal antibodies (LKM), smooth muscle antibodies (SMA) and antimitochondrial antibodies (AMA). Matched-pair analysis was performed matching one autoantibody-positive patient to three controls. Control patients had negative tests for all four antibodies. Analyses were performed for patients with a single positive autoantibody test and for patients with multiple positive autoantibody tests. A positive test result for ANA, LKM, SMA or AMA did not affect the physician's decision to initiate therapy with pegylated interferon and ribavirin. In addition, a positive test for one or multiple autoantibodies did not adversely affect sustained virologic response. There was no difference in fibrosis stage or alanine transaminase at baseline or during therapy irrespective of antibody status. Thyroid dysfunction was more frequent in patients with positive LKM antibodies (P = 0.004). Initiation of therapy for chronic hepatitis C and outcome were not affected by the presence of ANA, LKM, SMA or AMA. Routine testing of these autoantibodies seems not warranted. Determination of autoantibodies should be guided by individualized clinical decisions.

Abstract
BACKGROUND Epiphora is the result of hypersecretion or reduced tear outflow because of relative or absolute obstruction of the lacrimal system. For the treatment a specific surgical procedure is usually required. Herein we present the subjective and objective findings of 243 consecutive patients with non-irritative induced epiphora, who underwent an operation in a standardised therapy scheme, which is used at the eye departments of the Universities of Lübeck and Würzburg. PATIENTS AND METHODS In a retrospective cohort study 243 patients were included who underwent lateral tarsal strip (n = 72), external dacryocystorhinostomy (DCR) in the case of an absolute nasolacrimal duct obstruction (NLDO) (n = 116) and relative NLDO (n = 25), DCR with canalicular surgery (n = 18) and simple canalicular surgery (n = 12) with a follow-up of at least 6 month. Common patient and cosmetical satisfaction, intensity of symptoms and further symptoms of 168 patients were evaluated by sending a questionnaire with subsequent telephone survey. Objective findings were recorded from hospital charts. RESULTS 59.5% of the patients were free of complaints, 19.6% had an absolute decrease of symptoms (epiphora outside and in windy weather) and 20.8 % persistent epiphora (symptoms both in- and outside persisted). 81% of patients with absolute NLDO and 57% with relative NLDO were graded as being free of symptoms, 7% (24%) as a relative decrease and 12% (19%) as a persistence of symptoms. There was a significant difference in success between these indications (p = 0.018). Patency of the lacrimal system assessed by irrigation was found in 95% (absolute NLDO). Commonly, 73.8% were satisfied, 7.7% indifferent and 18.4 % not satisfied. 4 patients were cosmetically not satisfied. CONCLUSIONS Use of a standardised therapy scheme reduces the symptoms in 79.1% of the patients. In patients with absolute NLDO external DCR achieves an anatomic success rate of 95% and a subjective improvement in 88% with excellent cosmetic results. In comparison with absolute NLDO the success rate of relative NLDO is lower, but still with a subjective improvement in 81%. Our results show that postoperative success depends on the preoperative cause of the epiphora.

Abstract
Little is known about the epidemiology of chronic hepatitis C (CHC) in Germany and especially about the importance of transmission, duration of infection, genotypes, symptoms and quality of life of the patients. The current study prospectively evaluates epidemiological and clinical data of patients infected with the hepatitis C virus (HCV). Using online data entry, various characteristics of 10,326 untreated patients with CHC were documented from March 2003 until May 2006 in 352 centres all over Germany. Mean age of patients was 43.4 years. Patients infected by i.v. drug abuse were considerably younger (36.5 years) than the remaining patients (49.2 years). As indicated by their native language, 64.4% of the patients came from Germany and 19.2% from Russia. 61.7% were infected with genotype 1 and 34.9% with genotype 2 or 3. 45.5% of the patients had been infected by i.v. drug abuse. In at least 5.4% of the patients liver cirrhosis had been proved by biopsy. 63.5% of the patients felt an impairment of quality of life caused by CHC. In many patients infected with hepatitis C socio-economic issues are existent. This is reflected, i.e., in very high rates of unemployment in special subpopulations. Coinfections with hepatitis B and HIV occurred in 1.5% and 4.7%, respectively. Nearly 80% of patients were managed near their homes. The data of the 10 326 patients represent about 2% of all German patients with CHC. This database is up to now the largest of its kind and gives a representative insight into the epidemiological situation of CHC in Germany.

Abstract
BACKGROUND Evaluation of needling and 5-fluorouracil (5-FU) injections more than 4 months after preceding filtration surgery. PATIENTS AND METHOD Retrospective analysis of 17 eyes in 14 patients who underwent needling of the filtering bleb and administration of 5-FU by injection at least 4 months after trabeculectomy (TE) with mitomycin C (MMC; same surgeon throughout). Complete success was defined as a reduction of intraocular pressure (IOP) by >30% from the baseline value without further medication and, in cases of primary open-angle glaucoma, IOP of 18 mmHg. The mean period of follow-up was 8.1 months (3-24 months). RESULTS One to four needlings (Ø 1.6) with one to five injections (Ø 3.1) of 5-FU were performed as required according to clinical need an average of 31.3 months (4-108 m) after TE. The mean baseline IOP was 25 mmHg (+/-SD 6.02; median 25 mmHg). After needling and 5-FU injection the mean IOD at the last hospital visit was 13.64 mmHg (+/-SD 5.2, median 13 mmHg; p<0,001). Complete success was achieved in 82.4% of these cases. The mean reduction in IOP was 11.2 mmHg (0-22 mmHg). In the cases with successful outcome (14 of 17 eyes) the mean IOP reduction from baseline was 55%. Three eyes required further treatment. Complications encountered were hyphaema (2 cases), subconjunctival bleeding (1 case) and corneal erosion (3 cases). CONCLUSION Late needling and injections of 5-FU can restore filtering bleb function even over 4 months after initial surgery. The high success rate and low incidence of complications together with the simple procedure justify regarding this approach as an alternative that can be used before passing on to more invasive interventions.

Abstract
The relationship between childhood behavioral disturbance and comorbidity for adult psychiatric disorders has not been sufficiently investigated. Subjects of this report (N = 185) were offspring of parents with schizophrenia or affective disorder and of normal parents from the New York High-Risk Project. Data on childhood behavior at the mean age of 9.5 years were obtained in a parent interview at initial assessment in 1971-72. Adulthood outcomes were assessed through standardized interviews, and lifetime axis I diagnoses were based on Research Diagnostic Criteria. Subjects with comorbidity for axis I disorders exhibited significantly more behavioral problems as children, compared with those who developed either one or no psychiatric disorder in adulthood. This association was not biased by gender or parental diagnosis of psychiatric disorder. The findings emphasize that psychiatric comorbidity can be traced back to childhood and underline the importance of longitudinal observations in psychiatric research.

Abstract
OBJECTIVE An association between childhood behavioral disturbance and adulthood schizophrenia has been seen previously in retrospective or follow-back studies and in prospective studies. The authors examined the relationship between childhood behavioral problems and adulthood schizophrenia-related psychoses. Because a high rate of childhood behavioral problems is known to be associated with adult substance abuse, these analyses controlled for substance abuse. METHOD The subjects of this investigation (N = 185) were offspring of parents with schizophrenia or affective disorder and of normal parents from the New York High-Risk Project (sample A). Data on childhood behavioral problems were obtained in a parent interview at initial assessment in 1971-1972. Adulthood outcomes (schizophrenia-related psychoses, affective disorders, anxiety disorders, substance abuse) were based on lifetime axis I diagnoses according to the Research Diagnostic Criteria. RESULTS Substance abuse had a significant interaction with the clinical outcome groups. In subjects without substance abuse, those with schizophrenia-related psychoses had exhibited significantly more behavioral problems as children than had adult offspring with affective or anxiety disorder or with substance abuse only or no disorder. CONCLUSIONS These results support the view that schizophrenia-related psychoses can be followed back to early behavioral disturbances. The confounding effects of substance abuse should be statistically controlled in studies of longitudinal associations between childhood behavioral disturbance and axis I outcomes.

Abstract
BACKGROUND The New York High-Risk Project is a study of offspring of patients with schizophrenia (HRSz group) or affective illness (HRAff group) and psychiatrically normal parents (NC group) observed prospectively from childhood to adulthood. We herein present lifetime prevalence and comorbidity rates of Axis I disorders in subjects and their siblings from sample A of the project. METHODS Schedule for Affective Disorders and Schizophrenia-Lifetime Version interviews conducted with the offspring in adulthood were used to obtain diagnoses of Axis I disorders. RESULTS Schizophrenia and unspecified psychoses occurred only in the HRSz group. However, schizoaffective and psychotic affective disorders occurred equally in the HRSz and HRAff groups. Total rates of psychosis in these groups were significantly higher than in the NC group. All groups had similar rates of nonpsychotic affective and substance abuse disorders. The HRAff group, however, had significantly more total affective illness than the NC group and tended to have more anxiety disorders than the other groups. Comorbidity rates in the HRSz and HRAff groups were nearly twice those of the NC group. CONCLUSIONS The familial liabilities to schizophrenia and affective disorders show specificities and commonalities, differing markedly from each other in their expression of some disorders and sharing others. Patterns of comorbidity are generally, although not entirely, similar to these liabilities.

Abstract
The GRAFTAC skin stapler with absorbable tacs has been used to attach split-skin grafts in 28 patients, under a variety of clinical situations, and the outcomes studied. This knowledge has been reviewed in the light of our existing experience with the more familiar metal staple. Details of the patients and their conditions are presented, with two illustrative case histories, including one where both Graftac and metal staples were used. The relative costs were analysed and an attempt made to compare the cost-effectiveness of tacs and staples. A rationale for use of the more expensive GRAFTAC stapler is presented.

Abstract
A new treatment protocol was developed for colorectal carcinomas consisting of sequential administration of methotrexate, 5-fluorouracil and cytarabine. The latter was included into the protocol in order to suppress the DNA salvage pathway of tumour cells. The sequential high-dosage combination was administered to 34 patients with metastatic colorectal carcinoma, 23 patients had been pretreated with cytostatics. Remission could be achieved in 14 out of the 34 patients. Two patients with carcinoma of the rectum have complete clinical remission lasting for 7 months. Eight of the 14 patients responding to treatment had had cytostatic pretreatment. The median time of survival of patients in remission is 15 months, median survival of non-responders 4,3 months. Combination treatment was well tolerated. Leuko- and thrombocytopenia according to grade 3 and 4 of the WHO classification were only rarely observed.
