Abstract
OBJECTIVE During the last two decades, organised colorectal cancer (CRC) screening has been widely implemented. It remains to be established if screen-detected CRC (SD-CRC) is associated with reduced long-term requirements for treatment as compared with patients with non-screen-detected CRC (NSD-CRC). STUDY DESIGN AND METHODS This nationwide cohort study evaluated differences in treatment and healthcare contacts from the date of diagnosis to two years after comparing patients with SD-CRC and NSD-CRC. Data were collected from national healthcare registers, including patients aged 50-75 years and diagnosed with CRC between January 1st 2014 and March 31st 2018. Analyses were stratified into UICC stages and adjusted for sex, 5-year age groups, type of cancer (colonic/rectal), and Charlson comorbidity index score to address healthy user bias. RESULTS In total, 12,040 patients were included, 4708 with SD-CRC and 7332 with NSD-CRC. In patients with SD-CRC, the duration of hospitalisation and rate of emergency surgery were reduced by 38 % (relative risk [RR] = 0.62) and 66 % (RR = 0.34), respectively. Moreover, this group was characterised by a 75 % reduction in oncological outpatient visits (RR = 0.35) and a reduced number of treatments with chemotherapy (RR = 0.57) and radiotherapy (RR = 0.50). There were no significant differences between the two populations in the rates of metastasectomy and the number of contacts with primary healthcare providers. CONCLUSION Compared to patients with NSD-CRC, patients with SD-CRC experience less hospitalisation and treatment within the first two years after diagnosis.

Abstract
OBJECTIVES Colorectal cancer (CRC) is the third most common cancer. Many countries in Europe have already implemented systematic screening programmes as per the recommendations by the European Union. The impact of screening is highly dependent on participation rates. The aim of the study was to identify barriers, facilitators and modifiers to participation in systematised, stool sample-based, publicly financed CRC screening programmes. STUDY DESIGN Systematic review. METHODS A systematic search in PubMed, Embase, MEDLINE, CINAHL, Cochrane CENTRAL, Google Scholar and PsycINFO was undertaken. We included both qualitative and quantitative studies reporting on barriers and facilitators (excluding sociodemographic variables) to participation in stool sample-based CRC screening. Barriers and facilitators to participation were summarised and analysed. RESULTS The inclusion criteria were met in 21 studies. Reported barriers and facilitators were categorised into the following seven themes (examples): psychology (fear of cancer), religion (believing cancer is the will of God), logistics (not knowing how to conduct the test), health-related factors (mental health), knowledge and awareness (lack of knowledge about the test), role of the general practitioner (being supported in taking the test by the general practitioner), and environmental factors (knowing someone who has participated in a screening programme). Six studies reported that non-participation was not due to a negative attitude towards screening for CRC. CONCLUSION Many barriers to screening were found. It is important to work with peoples' fear of screening. Moreover, this review suggests that it might be possible to increase participation rates, if the population-wide awareness and knowledge of potential health benefits of CRC screening are increased and proper logistical support is provided.

Abstract
Repeated quantitative analyses of the blood plasma yield valuable data allowing us to form a clearer idea of the metabolic processes involved in various body states of the mammalian organism. Quantitative analyses of the plasma have hitherto usually paid little attention to the influence of the total blood fluid amount as well as to the blood cell : plasma volume ratio which affects the absolute amount of the substance under study. The present paper describes 4 different levels of evaluating quantitative analyses of the blood plasma.

Abstract
SummaryThe version 2 of the procedure guideline for iodine-131 whole-body scintigraphy for differentiated thyroid cancer is an update of the procedure guideline published in 1999. The following statements are added or modified: The two alternatives of an endogenous TSH-stimulation by the withdrawal of the thyroidal hormone medication and of an exogenous TSH-stimulation by the injection of the recombinant human TSH (rhTSH) have an equal sensitivity for the diagnostic use of radioiodine and for the measurement of thyroglobulin. Image acquisition under rhTSH is obtained approximately 48 h after the radioiodine administration, while an interval of about 72 h is preferred under endogenous TSH-stimulation. If iodine-negative metastases are expected, the feasibility of scintigraphy using 99mTc sestamibi or preferably positron emission tomography using 18F-fluorodeoxyglucose should be considered. The sensitivity of FDG-PET is increased by TSH-stimulation. Before planning the iodine-131 scintigraphy the patient has to avoid iodine-containing medication and the possibility of additives of iodine in vitamin- and electrolyte-supplementation has to be considered.

Abstract
SummaryThe version 2 of the guideline for diagnostic standards of thyroid disorders is an update of the guideline published in 1999 and describes standards of in vitro and in vivo procedures. The following statements are modified: In vitro procedures: When measurement of the TSH-receptor antibodies is indicated, the guideline recommends the use of a second generation assay (recombinant human TSH-receptor as antigen). The functional assay sensitivity for the measurement of thyroglobulin should reach a value ≤1 ng/ml. Moleculargenetic tests (RET proto-oncogen) are indicated in patients with a newly diagnosed medullary thyroid cancer and in the relatives of patients with hereditary medullary thyroid cancer. In vivo procedures: The sonographic examination should use a probe with a frequency of at least 7.5 MHz. Indications for the thyroid scintigraphy: nodule size ≥1 cm in diameter, autonomous goitre/nodule with clinical or subclinical hyperthyroidism, necessity of a differentiation between Graves’ disease and chronic lymphocytic thyroiditis, therapy control after a definitive treatment and – in individual cases – the follow-up of untreated autonomous nodules.

Abstract
SummaryThe version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves’ disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves’ disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient’s preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients’ preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3rd version.

Abstract
SummaryThe version 2 of the procedure guideline for radioiodine test is an update of the guideline published in 1999. The following statements were added or modified: The procedure guideline discusses the pros and cons of a single measurement or of repeated measurements of the iodine-131 uptake and their optimal timing. Different formulas are described when one, two or three values of the radioiodine kinetic are available. The probe with a sodium iodide crystal, alternative or additionally the gamma-camera using the ROI-technique are instrumentations for the measurement of iodine-131 uptake. A possible source of error is an inappropriate measurement (sonography) of the target volume. The patients’ preparation includes the withdrawal of antithyroid drugs 2-3 days before radioiodine administration. The patient has to avoid iodine-containing medication and the possibility of additives of iodide in vitamin- or electrolyte-supplementation has to be considered.

Abstract
SummaryThe procedure guidelines for radioiodine therapy (RIT) of differentiated thyroid cancer (version 2) are the counterpart to the procedure guidelines for 131I whole-body scintigraphy (version 2) and specify the interdisciplinary guidelines for thyroid cancer of the Deutsche Krebs-gesellschaft and the Deutsche Gesellschaft für Chirurgie concerning the nuclear medicine part. Compared with version 1 facultative options for RIT can be chosen in special cases: ablative RIT for papillary microcarcinoma ≤1 cm, ablative RIT for mixed forms of anaplastic and differentiated thyroid cancer, and RIT in patients with a measurable or increasing thyroglobulin concentration but without detectable metastases by imaging. The description of the pretherapeutic dosimetry now includes the isotopes 123I and 124I as well as a broader range of the activity of 131I. Activities of 2-5 GBq 131I are recommended for the first ablative RIT. If high accumulative activities of 131I are expected, men who have not yet finished their family planning should be advised to the option of sperm cryoconservation. An interdisciplinary consensus is necessary whether the new TNM-classification (UICC, 6th edition, 2002) will lead to modified recommendations for surgical or nuclear medicine therapy, especially for the surgical completeness and for the ablative RIT of pT1 papillary cancer.

Abstract
SummaryVersion 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus on decision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation.

Abstract
SummaryThe version 3 of the procedure guideline for thyroid scintigraphy is an update of the procedure guideline previously published in 2003. The interpretation of the scintigraphy requires the knowledge of the patients' history, the palpation of the neck, the laboratory parameters and of the sonography. The interpretation of the technetium-99m uptake requires the knowledge of the TSH-level. As a consequence of the improved alimentary iodine supply the 99mTc-uptake has decreased; 100 000 counts per scintigraphy should be acquired. For this, an imaging time of 10 minutes is generally needed using a high resolution collimator for thyroid imaging.

Abstract
SummaryVersion 3 of the procedure guideline for 131I whole-body scintigraphy (WBS) is the counterpart to the procedure guideline for radioiodine therapy (version 3) and specify the interdisciplinary guideline for thyroid cancer of the Deutsche Krebsgesellschaft concerning the nuclear medicine part. 131I WBS 3–6 months after 131I ablation remains a standard procedure in an endemic area for thyroid nodules and the high frequency of subtotal surgical procedures. Follow-up without 131I WBS is only justified if the following preconditions are fulfilled: low-risk group pT1–2, pN0 M0 with histopathologically confirmed pN0, 131I uptake <2%, 131I WBS during ablation without any suspicious lesion, stimulated thyroglobulin (Tg)-level 3–6 months after ablation <2 ng/mL, and absence of anti-thyroglobulin- antibodies with normal recovery-testing. If patients from the low-risk group show normal 131I WBS 3–6 months after ablation and stimulated Tg is of <2 ng/mL, there will be no need for additional routine 131I WBS. If patients from the high-risk group show normal 131I WBS and stimulated Tg-level of <2 ng/mL 3–6 months after ablation, the follow- up care should include repeated stimulated Tgmeasurements. If the Tg-level remains below 2 ng/mL, an additional 131I WBS will be not necessary. The recommended intervals for stimulated Tg-testing are adapted to the prior intervals for 131I WBS-testing in the high-risk group. Increased anti-thyroglobulin-antibodies or incomplete recovery-testing make an individual strategy of follow- up care necessary, which include 131I WBS.

Abstract
SummaryThe procedure guideline for radioiodine therapy (RIT) of differentiated thyroid cancer (version 3) is the counterpart to the procedure guideline for 131I whole-body scintigraphy (version 3) and specify the interdisciplinary guideline for thyroid cancer of the Deutsche Krebsgesellschaft concerning the nuclear medicine part. Recommendation for ablative 131I therapy is given for all differentiated thyroid carcinoma (DTC) >1 cm. Regarding DTC ≤1 cm 131I ablation may be helpful in an individual constellation. Preparation for 131I ablation requires low iodine diet for two weeks and TSHstimulation by withdrawal of thyroid hormone medication or by use of recombinant human TSH (rhTSH). The advantages of rhTSH (no symptoms of hypothyroidism, lower blood activity) and the advantages of endogenous TSHstimulation (necessary for 131I-therapy in patients with metastases, higher sensitivity of 131I whole-body scan) are discussed. In most centers standard activities are used for 131I ablation. If pretherapeutic dosimetry is planned, the diagnostic administration of 131I should not exceed 1–10 MBq, alternative tracers are 123I or 124I. The recommendations for contraception and family planning are harmonized with the recommendation of ATA and ETA. Regarding the best possible protection of salivary glands the evidence is insufficient to recommend a specific setting. To minimize the risk of dental caries due to xerostomia patients should use preventive strategies for dental hygiene.

Abstract
Accidents constitute one of the greatest risks to children, yet there are few medical reports that discuss the subject of accidental asphyxia. However, a systematic analysis of all documented cases in Germany over the years 2000-2008 has now been conducted, aiming at identifying patterns of accidental asphyxia, deducing findings, defining avoidance measures and recommending ways of increasing product safety and taking possible precautions. The analysis is based on a detailed retrospective analysis of all 91 relevant autopsy reports from 24 different German forensic institutes. A variety of demographic and morphological data was systematically collected and analysed. In 84 of the 91 cases, the sex of the victim was reported, resulting in a total of 57 boys (68 %) and 27 girls (32 %). The age spread ranged between 1 day and 14 years, with an average of 5.9 years. Most accidents occurred in the first year of life (20 %) or between the ages of 1 and 2 years (13 %). In 46 % of cases, the cause of death was strangulation, with the majority occurring in the home environment. In 31 % of all cases, the cause of death was positional asphyxia, the majority resulting from chest compression. In 23 % of cases, the cause of death was aspiration, mainly of foreign bodies. Today, accidental asphyxiation is a rare cause of death in children in Germany. Nevertheless, the majority of cases could have been avoided. Future incidence can be reduced by implementing two major precautions: increasing product safety and educating parents of potentially fatal risks. Specific recommendations relate to children's beds, toys and food.

Abstract
The cause of décollement is usually considered to be tangential brute blunt force impacting the body surface especially in case of hitting or running-over injury of the pedestrian's body by a car. The term rolling effect or rolling mechanism is used as well. The dissociation of tissue layers with other epiphenomenon occurs. The presented group of 152 décollement determined in 103 autopsy cases during the 4 years period comprises the observation of décollement of different etiology of the injuries (traffic accidents, falls from the high, compression of the torso); in the traffic accidents the occurrence in various participants of the traffic, not only in the case of the collision of the pedestrians with various traffic vehicles, but also in drivers of various traffic vehicles, and fellow-travelers as well. The topic, the localization, the content, the extent, and vital reaction and combination injuries were followed-up. According to the variability of the injury etiology, not restricted to the traditional conception of the décollement mechanism, it is obvious that the passed on rule by far is not covering the whole content of this concept. We didn't find any alternative interpretation of until now presented mechanism in the literature. The medical literature focuses mostly on the clinical aspect of this injury. In this paper, the biomechanics of the décollement origin also in case of the tissue compression by the pressure applied perpendicularly to the body surface, the dependences on physical properties of the actively or passively affecting object, the relevance of the ratio of the tissue structures compression in one direction and transversal dilation in other two directions according to the Poisson's constant, the question of tangential factor of the force in case of vertical falling on the horizontal plane, and biomechanical relations in case of body landing on an oblique surface are discussed. The mechanism of décollement is more complex as presented until now. The forensic interpretation of findings should reflex the above-mentioned facts.

Abstract
The procedure guideline for radioiodine therapy (RIT) of differentiated thyroid cancer (version 3) is the counterpart to the procedure guideline for (131)I whole-body scintigraphy (version 3) and specify the interdisciplinary guideline for thyroid cancer of the Deutsche Krebsgesellschaft concerning the nuclear medicine part. Recommendation for ablative (131)I therapy is given for all differentiated thyroid carcinoma (DTC) >1 cm. Regarding DTC < or =1 cm (131)I ablation may be helpful in an individual constellation. Preparation for (131)I ablation requires low iodine diet for two weeks and TSH-stimulation by withdrawal of thyroid hormone medication or by use of recombinant human TSH (rhTSH). The advantages of rhTSH (no symptoms of hypothyroidism, lower blood activity) and the advantages of endogenous TSH-stimulation (necessary for (131)I-therapy in patients with metastases, higher sensitivity of (131)I whole-body scan) are discussed. In most centers standard activities are used for (131)I ablation. If pretherapeutic dosimetry is planned, the diagnostic administration of (131)I should not exceed 1-10 MBq, alternative tracers are (123)I or (124)I. The recommendations for contraception and family planning are harmonized with the recommendation of ATA and ETA. Regarding the best possible protection of salivary glands the evidence is insufficient to recommend a specific setting. To minimize the risk of dental caries due to xerostomia patients should use preventive strategies for dental hygiene.

Abstract
Version 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus on decision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation.

Abstract
The version 3 of the procedure guideline for radioiodine test is an update of the guideline previously published in 2003. The procedure guideline discusses the pros and cons of a single measurement or of repeated measurements of the iodine-131 uptake and their optimal timing. Different formulas are described when one, two or three values of the radioiodine kinetic are available. The probe with a sodium-iodine crystal, alternatively or additionally the gamma-camera using the ROI-technique are instrumentations for the measurement of iodine-131 uptake. A possible source of error is an inappropriate measurement (sonography) of the target volume. The patients' preparation includes the withdrawal of antithyroid drugs 2-3 days before radioiodine administration. The patient has to avoid iodine-containing medication and the possibility of additives of iodine in vitamin- and electrolyte-supplementation has to be considered.

Abstract
Version 3 of the procedure guideline for (131)I whole-body scintigraphy (WBS) is the counterpart to the procedure guideline for radioiodine therapy (version 3) and specify the interdisciplinary guideline for thyroid cancer of the Deutsche Krebsgesellschaft concerning the nuclear medicine part. (131)I WBS 3-6 months after (131)I ablation remains a standard procedure in an endemic area for thyroid nodules and the high frequency of subtotal surgical procedures. Follow-up without (131)I WBS is only justified if the following preconditions are fulfilled: low-risk group pT1-2, pN0 M0 with histopathologically confirmed pN0, (131)I uptake <2%, (131)I WBS during ablation without any suspicious lesion, stimulated thyroglobulin (Tg)-level 3-6 months after ablation <2 ng/mL, and absence of anti-thyroglobulin-antibodies with normal recovery-testing. If patients from the low-risk group show normal (131)I WBS 3-6 months after ablation and stimulated Tg is of <2 ng/mL, there will be no need for additional routine (131)I WBS. If patients from the high-risk group show normal (131)I WBS and stimulated Tg-level of <2 ng/mL 3-6 months after ablation, the follow-up care should include repeated stimulated Tg-measurements. If the Tg-level remains below 2 ng/mL, an additional (131)I WBS will be not necessary. The recommended intervals for stimulated Tg-testing are adapted to the prior intervals for (131)I WBS-testing in the high-risk group. Increased anti-thyroglobulin-antibodies or incomplete recovery-testing make an individual strategy of follow-up care necessary, which include (131)I WBS.

Abstract
The version 3 of the procedure guideline for thyroid scintigraphy is an update of the procedure guideline previously published in 2003. The interpretation of the scintigraphy requires the knowledge of the patients' history, the palpation of the neck, the laboratory parameters and of the sonography. The interpretation of the technetium-99m uptake requires the knowledge of the TSH-level. As a consequence of the improved alimentary iodine supply the (99m)Tc-uptake has decreased; 100,000 counts per scintigraphy should be acquired. For this, an imaging time of 10 minutes is generally needed using a high resolution collimator for thyroid imaging.

Abstract
To establish reliable methods to aid the timing of brain damage after traumatic brain injury (TBI), brain tissue from 56 autopsy cases with TBI and known survival times, ranging from a few minutes to 126 days, were tested for apoptotic changes to the neuronal and glial cells. Apoptosis was established using the TdT-mediated dUTP nick end labelling (TUNEL) method of in-situ labelling and immunohistochemical reaction of caspase 3. In addition, cellular reaction and astroglial cell differentiation were investigated using histological and immunohistochemical markers. From a survival time of 120 min up to 12 days, TUNEL-positive apoptotic neuronal cells were frequently detected in the contusion zone. The earliest positive caspase 3 reaction in cortical neurons was evident after a posttraumatic interval of 80 min. Detection of apoptotic glial cells using the TUNEL technique showed that as in the case of neuronal cells, the earliest positive TUNEL reaction was obtained after 110 min. In cases of survival times of 120 min up to 4 days, apoptotic glial cells could frequently be detected. However, the first caspase 3-positive glial cells appeared 5 h after injury. Cerebral apoptosis was significantly associated with TBI cases as compared to control cases (P<0.001). The reference histological findings of neutrophilic granulocytes, CD3-positive T-lymphocytes, CD68-positive activated microglial cells/macrophages and TUNEL-positive neuronal cells increases the degree of certainty in determining the probable age of traumatic brain injury to 87.5%.

Abstract
It is well known that under physiological conditions, the Tg molecule is the substrate for the hormones triiodothyronine and thyroxine. Its function outside the thyroid gland is unknown. Under certain pathologic conditions, an increase in Tg concentrations in the blood can occur, a phenomenon that is used in the clinical diagnosis of certain thyroid disorders. However, fatal traumatic brain injuries (TBI) can also produce a raised Tg concentration in blood. In such cases, mean (n=151) Tg concentrations of 405.8+/-353.3 ng/mL have been observed, with the values in 57% of these cases exceeding 200 ng/mL. Since it was possible to rule out specifically any thyroid disorders in these cases, the raised values may be explained by the effect of TSH in the spectrum of the "hypothalamic-pituitary-thyroid axis." This assumption has been substantiated by immunohistochemical tests for TSH and Tg. Compared with the controls (sudden unnatural deaths: Tg 23.3+/-27.6 ng/mL), the raised Tg values in the TBI cases were usually accompanied by a reduction in the intensity of immunohistochemical reactions relating to TSH and Tg. The hypophysis showed evidence of significant damage with morphologic changes such as edema, hemorrhages, and focal necrosis in association with reduced TSH levels.

Abstract
The study presents five fatal cases of poisoning with Taxus spp., all of which were suicides of young people aged between 16 and 26 years. Yew leaves were consumed in four fatalities, whereas a mash from Taxus was ingested in one case. No relevant concentrations of alcohol, narcotic drugs, and pharmaceuticals were determined in postmortem toxicological screening. At forensic autopsy, a widely dilated pupil was found in two decedents. Furthermore, autopsy showed unspecific findings of intoxication in all cases: acute blood congestion of lungs, liver, kidney, and brain as well as dilated cardiac ventricles. No signs of violence could be found in any of the fatalities. Yew leaves were identified in four cases in the stomach and duodenum. 3,5-Dimethoxyphenol, the aglycon of the Taxus ingredient taxicatine, was determined as toxicological evidence for the absorption of yew ingredients. Taxus intoxication could be confirmed by 3,5-dimethoxyphenol concentrations in cardiac blood between 31 and 528 ng/ml for all cases. 3,5-Dimethoxyphenol was also detected in stomach contents as well as in urine, liver, kidneys, and brain samples. Based on the different concentrations of 3,5-dimethoxyphenol determined in the cardiac blood samples, it was concluded that the form of ingestion plays a decisive role in the process of poisoning. Finally, a toxic range for Taxus poisoning based on 3,5-dimethoxyphenol as marker substance is proposed as orientation.

Abstract
Homicide with subsequent hiding of the body using setting in concrete or sealing with bricks are rarely seen forensic cases. The article describes the circumstances and findings of six cases in which bodies were encased with concrete and/or bricks. In all cases, the offenders were male, in one case together with his wife and--except for one case--the victims were related to the offender. The causes of death were heterogeneous (suffocation, blunt force, shot) and the motive mainly domestic quarrel. Setting corpses in concrete and/or sealing with bricks does not prevent smell, slows decomposition and therefore complicates the estimation of the post mortem interval.

Abstract
The study presents a case of non-fatal poisoning with oleander blooms in a 47-year-old female, with emphasis on the importance of toxicological service in a clinical emergency. After repeated vomiting at home, the patient was admitted at the hospital with cardiac symptoms more than 18 h after the ingestion. Serum samples were assayed immunochemically for digitoxin-related compounds by electrochemiluminescent immunoassay, and using HPLC/MS/MS analysis for oleandrin, the main cardiac glycoside of Nerium oleander. Confirming the non-specific immunoassay results, which are often clinically over-interpreted, oleandrin was detected by HPLC/MS/MS in the serum sample in a concentration of 1.6 ng/ml upon admission. Comparison with previous reports indicates that single compound analysis only permits a toxicological assessment for oleander poisoning and results in the proposal to classify an oleandrin level between 1.0 and 2.0 ng/ml as toxic blood plasma/serum concentration.

Abstract
In the past years an ongoing controversial debate exists in Germany, regarding quality of the coroner's inquest and declaration of death by physicians. We report the case of a 90-year old female, who was found after an unknown time following a suicide attempt with benzodiazepine. The examination of the patient showed livores (mortis?) on the left forearm and left lower leg. Moreover, rigor (mortis?) of the left arm was apparent which prevented arm flexion and extension. The hypothermic patient with insufficient respiration was intubated and mechanically ventilated. Chest compressions were not performed, because central pulses were (hardly) palpable and a sinus bradycardia 45/min (AV-block 2 degrees and sole premature ventricular complexes) was present. After placement of an intravenous line (17 G, external jugular vein) the hemodynamic situation was stabilized with intermittent boli of epinephrine and with sodium bicarbonate. With improved circulation livores and rigor disappeared. In the present case a minimal central circulation was noted, which could be stabilized, despite the presence of certain signs of death ( livores and rigor mortis). Considering the finding of an abrogated peripheral perfusion (livores), we postulate a centripetal collapse of glycogen and ATP supply in the patients left arm (rigor), which was restored after resuscitation and reperfusion. Thus, it appears that livores and rigor are not sensitive enough to exclude a vita minima, in particular in hypothermic patients with intoxications. Consequently a careful ABC-check should be performed even in the presence of apparently certain signs of death, to avoid underdiagnosing a vita minima. Additional ECG- monitoring is required to reduce the rate of false positive declarations of death. To what extent basic life support by paramedics should commence when rigor and livores are present until physician DNR order, deserves further discussion.

Abstract
The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3rd version.

Abstract
Paratonsillar abscesses are preferably treated by abscess tonsillectomy as operative therapy. The casuistry of a patient aged 17 who was tonsillectomized for a paratonsillar abscess and died after 12 days prompted a discussion on the scope of preoperative diagnostics. The clinical examination and anamnesis of the young man prior to the operation did not give evidence of any concomitant diseases. It was only through extensive microscopic investigations of the myocardium after autopsy that inflammatory infiltrates of the epicardium, endocardium and myocardium in the vicinity of portions of the conduction system were detected. The relevance of autopsy to the quality assurance in clinical activities is emphasized. Legal questions of possible negligent homicide as a result of the failure to take diagnostic and therapeutic measures are raised.

Abstract
The urokinase-type plasminogen activator receptor (uPAR) plays a critical role in cartilage degradation during osteoarthritis as it regulates pericellular proteolysis mediated by serine proteinases. Another important family of proteinases responsible for ECM destruction in arthritis are the matrix metalloproteinases (MMPs). MMPs are regulated by IL-1beta, a cytokine that plays a pivotal role in pathogenesis of osteoarthritis. This study was undertaken to address two questions: 1. Is uPAR-expression regulated by proinflammatory cytokines such as IL-1beta? 2. Does a functional co-localization exist between uPAR and MMPs? By immunohistochemical analysis we observed enhanced expression of uPAR on chondrocytes derived from osteoarthritic human cartilage compared to non-osteoarthritic controls. We found an IL-1beta-mediated expression of uPAR by immunoelectron microscopy. Western blot analysis demonstrated that IL-1beta-stimulated expression of uPAR on chondrocytes in vitro increased in a dose-dependent manner. Furthermore, we found a functional co-localization between uPAR and MMP-9 on IL-1beta-stimulated chondrocytes by means of a co-immunoprecipitation assay. Expression of uPAR in osteoarthritic cartilage but not in healthy cartilage suggests that uPAR plays a role in cartilage breakdown. We propose that uPAR-mediated effects e.g. pericellular proteolysis are one of other cytokine (IL-1beta)-mediated events that contribute to the pathogenesis of osteoarthritis. Furthermore, we found that MMPs and uPAR were part of the same cell surface complexes in chondrocytes. This finding underlines a functional interaction between MMPs and the serine proteinase system in the fine regulation of pericellular proteolysis. Interfering with uPAR signaling may present a novel target in arthritis therapy to prevent excessive proteolytic degradation.

Abstract
The procedure guidelines for radioiodine therapy (RIT) of differentiated thyroid cancer (version 2) are the counter-part to the procedure guidelines for (131)I whole-body scintigraphy (version 2) and specify the interdisciplinary guidelines for thyroid cancer of the Deutsche Krebsgesellschaft and the Deutsche Gesellschaft für Chirurgie concerning the nuclear medicine part. Compared with version 1 facultative options for RIT can be chosen in special cases: ablative RIT for papillary microcarcinoma </=1 cm, ablative RIT for mixed forms of anaplastic and differentiated thyroid cancer, and RIT in patients with a measurable or increasing thyroglobulin concentration but without detectable metastases by imaging. The description of the pretherapeutic dosimetry now includes the isotopes (123)I and (124)I as well as a broader range of the activity of (131)I. Activities of 2-5 GBq (131)I are recommended for the first ablative RIT. If high accumulative activities of (131)I are expected, men who have not yet finished their family planning should be advised to the option of sperm cryoconservation. An interdisciplinary consensus is necessary whether the new TNM-classification (UICC, 6(th) edition, 2002) will lead to modified recommendations for surgical or nuclear medicine therapy, especially for the surgical completeness and for the ablative RIT of pT1 papillary cancer.

Abstract
Recent studies have demonstrated enhanced expression of vascular endothelial growth factor and vascular endothelial growth factor receptor (VEGFR)-1 and -2 in chondrocytes of rheumatoid and osteoarthritic cartilage. Since expression of VEGFR-3 ( Flt-4) in chondrocytes has not yet been investigated, we studied the distribution of VEGFR-3 in osteoarthritic cartilage samples by immunohistochemistry and immunoelectron microscopy. Furthermore, we looked for functional colocalization of VEGFR-3 with the signal transduction receptor beta(1)-integrin. Superficial osteoarthritic chondrocytes exhibited VEGFR-3 expression in the cytoplasm and on the cell membrane. Using western blotting we could demonstrate that interleukin-1 beta (IL-1 beta) stimulates the expression of VEGFR-3 in chondrocytes in vitro in a dose-dependent manner. By coimmunoprecipitation assay we found a functional complex between the beta(1)-integrin and VEGFR-3 in IL-1 beta-stimulated chondrocytes indicating that activated VEGFR-3 may interact with beta(1)-integrin and associated subcellular pathways in osteoarthritic chondrocytes. Taken together with results of previous studies showing that beta(1)-integrins were also associated with other surface receptors and proteins in chondrocytes that cause cartilage destruction in arthritis (for example, urokinase-type plasminogen activator receptor and matrix metalloproteinases), we can hypothesize that signal transduction by these receptor complexes via beta(1)-integrins may play a crucial role in pathogenesis of osteoarticular disorders. Further work needs to be done to elucidate downstream signaling events activated by these receptors.

Abstract
The version 2 of the guideline for diagnostic standards of thyroid disorders is an update of the guideline published in 1999 and describes standards of in vitro and in vivo procedures. The following statements are modified: In vitro procedures: When measurement of the TSH-receptor antibodies is indicated, the guideline recommends the use of a second generation assay (recombinant human TSH-receptor as antigen). The functional assay sensitivity for the measurement of thyroglobulin should reach a value < or =1 ng/ml. Molecular genetic tests (RET proto-oncogene) are indicated in patients with a newly diagnosed medullary thyroid cancer and in the relatives of patients with hereditary medullary thyroid cancer. In vivo procedures: The sonographic examination should use a probe with a frequency of at least 7.5 MHz. Indications for the thyroid scintigraphy: nodule size > or =1 cm in diameter, autonomous goitre/nodule with clinical or subclinical hyperthyroidism, necessity of a differentiation between Graves' disease and chronic lymphocytic thyroiditis, therapy control after a definitive treatment and - in individual cases - the follow-up of untreated autonomous nodules.

Abstract
The version 2 of the procedure guideline for radioiodine test is an update of the guideline published in 1999. The following statements were added or modified: The procedure guideline discusses the pros and cons of a single measurement or of repeated measurements of the iodine-131 uptake and their optimal timing. Different formulas are described when one, two or three values of the radioiodine kinetic are available. The probe with a sodium iodide crystal, alternative or additionally the gamma-camera using the ROI-technique are instrumentations for the measurement of iodine-131 uptake. A possible source of error is an inappropriate measurement (sonography) of the target volume. The patients' preparation includes the withdrawal of antithyroid drugs 2-3 days before radioiodine administration. The patient has to avoid iodine-containing medication and the possibility of additives of iodide in vitamin- or electrolyte-supplementation has to be considered.

Abstract
The version 2 of the procedure guideline for iodine-131 whole-body scintigraphy for differentiated thyroid cancer is an update of the procedure guideline published in 1999. The following statements are added or modified: The two alternatives of an endogenous TSH-stimulation by the withdrawal of the thyroidal hormone medication and of an exogenous TSH-stimulation by the injection of the recombinant human TSH (rhTSH) have an equal sensitivity for the diagnostic use of radioiodine and for the measurement of thyroglobulin. Image acquisition under rhTSH is obtained approximately 48 h after the radioiodine administration, while an interval of about 72 h is preferred under endogenous TSH-stimulation. If iodine-negative metastases are expected, the feasibility of scintigraphy using (99m)Tc sestamibi or preferably positron emission tomography using (18)F-fluorodeoxyglucose should be considered. The sensitivity of FDG-PET is increased by TSH-stimulation. Before planning the iodine-131 scintigraphy the patient has to avoid iodine-containing medication and the possibility of additives of iodine in vitamin- and electrolyte-supplementation has to be considered.

Abstract
The version 2 of the procedure guideline for thyroid scintigraphy is an update of the procedure guideline published in 1999. The procedure guideline considers the current amendment of legislative rules (Richtlinie Strahlenschutz in der Medizin 2002). Indication and use of radiopharmaceuticals have to be confirmed by the specialist in nuclear medicine. Activities of 75 MBq technetium-99m, respectively of 10 MBq iodine-123 should not be exceeded without an individual justification. The interpretation of the scintigraphy requires the knowledge of the patients' history, the palpation of the neck, the laboratory parameters, and of the sonography. The interpretation of the technetium-99m uptake requires the knowledge of TSH concentration.

Abstract
UNLABELLED In addition to evidence of the vital reaction it is important from the forensic aspect to assess the age of wounds, in particular in wounds with a short time of survival. To both can contribute detection of adhesive molecules, identified in recent years, possibly in combination with other markers of early stages of reparative inflammation. The submitted paper comprises the results of investigation of 465 skin wounds. The investigated samples were obtained from necroptic material, excision from wounds of treated patients and from experimental injuries in mice. Assessment of the age of injuries by means of endothelial adhesive molecules was made in paraffin sections after transfer into Varioclave and using the ABC techniqueref.. In human material a strong positive reaction of ICAM-1 was observed first after 1 and a half hours and latest after 3 and a half days, in P-selectin first after 3 mins., latest after 7 hours, in E-selectin first after 1 hour and latest after 17 days, in VCAM-1 first after 3 hours and latest 3 and a half days after the development of the injury. Expression of L-selectin was not typical for the injury. In skin injuries of mice positive immunohistochemical reactions were found as a rule sooner than in skin injuries of humans. Fibronectin was detected in paraffin sections from 70 skin wounds of dissected subjects immunohistochemically by the indirect immunoperoxidase reaction and by the use of the ABC technique labelled with alkaline phosphatase. Positive evidence was observed first after 5 minutes and latest after 8 hours. CONCLUSION Detection of a rise of expression of ICAM-1, VCAM-1 and P- and E. selectin and the formation of basic netlike fibronectin structures improves the assessment of the age of wounds with a short survival period.

Abstract
Scars of human skin can on occasions provide a very useful ancillary method of identification of an unknown deceased. If the age of any visible scars can be estimated objectively, then this might be of some assistance in the identification procedure. Melanocytes migrate into scar tissue as it ages and their number within the epidermal basal layers alters during the maturation of a scar. A total of 64 scar samples, all from previous surgical sites, were taken in the course of autopsies. Each scar was stained by the H & E method and by an immunohistochemical method using polyclonal S100 antibody. The number of melanocytes in the basal layer was counted in the epidermis overlying the scar and in the adjacent epidermis. This ratio was matched with the documented age of the scar and a statistical evaluation was carried out matching the chronological age of the scars to the melanocyte/basal epidermal cells ratio. Scars with a duration between 1 and 3 years showed a mean ratio of 1.85 and a maximum ratio of 1.94, 1.8 years after a surgical operation. The number of basal melanocytes declined thereafter and reached that of the adjacent epidermis after about 10 years. The immunohistochemical detection of melanocytes can be used for the diagnostic ageing of scars which may be a valuable contribution to improve the identification of unknown deceased persons.

Abstract
The adhesion molecules identified in recent years can help improve the diagnosis of the wound age, especially of injuries with a short survival time. This is also indicative of the vitality of the wounds. The material investigated in the study originated from 465 skin wounds. The samples were taken from human autopsy material, during the surgical treatment of wounds (excision) of patients and from experimental incised wounds of mice. To judge the age of skin wounds the endothelial adhesion molecules were detected in paraffin sections after autoclaving and using the ABC technique. Human skin wounds: strong positive staining was observed of ICAM-1 1.5 h at the earliest and 3.5 days at the latest, for the P-selectin 3 min at the earliest and 7 h at the latest, for the E-selectin 1 h at the earliest and 17 days at the latest and for VCAM-1 3 h at the earliest and 3.5 days at the latest after the time of injury. The L-selectin was expressed constitutively. Mice skin wounds: strong positive immunohistochemical reactions were found as a rule earlier than in human skin wounds. The detection of an increased expression of ICAM-1, VCAM-1 and P- and E-selectins can improve the wound age assessment in injuries with short survival times.
