RESUMO

PURPOSE: Due to the demographic shift, the number of older people suffering from hearing loss and from cognitive impairment increases. Both are closely related and hard to differentiate as most standard cognitive test batteries are auditory-based and hearing-impaired individuals perform worse also in non-auditory test batteries. Therefore, reference data for hearing-impaired are mandatory. METHODS: The computer-based battery ALAcog assesses multiple cognitive domains, such as attention, (delayed) memory, working memory, inhibition, processing speed, mental flexibility and verbal fluency. A data set of 201 bilaterally hearing-impaired subjects aged ≥ 50 (mean 66.6 (SD 9.07)) was analysed. The LMS method, estimated curves for the 10th, 25th, 50th, 75th and 90th percentile were calculated, and classified according to age, starting from the age of 50. RESULTS: Cognitive function shows a decline in all subtests as people age, except for verbal fluency, which remains almost stable over age. The greatest declines were seen in recall and delayed recall and in mental flexibility. Age and hearing ability did not correlate (p = 0.68). However, as people age, inter-subject variability of cognitive test results increases. This was especially the case for inhibition. Cognitive function was not correlated with hearing ability (each p ≥ 0.13). CONCLUSION: The present results make an approach to establish reference data for a comprehensive non-auditory test battery in a large sample of elderly hearing-impaired people which can be used as a simple tool to better contextualise cognitive performance beyond mean and median scores.

RESUMO

Background: Despite recent improvements in colonic cancer surgery, the rate of anastomotic leakage after right hemicolectomy is still around 6-7 per cent. This study examined whether anastomotic technique (handsewn or stapled) after open right hemicolectomy for right-sided colonic cancer influences postoperative complications. Methods: Patient data from the German Society for General and Visceral Surgery (StuDoQ) registry from 2010 to 2017 were analysed. Univariable and multivariable analyses were performed. The primary endpoint was anastomotic leakage; secondary endpoints were postoperative ileus, complications and length of postoperative hospital stay (LOS). Results: A total of 4062 patients who had undergone open right hemicolectomy for colonic cancer were analysed. All patients had an ileocolic anastomosis, 2742 handsewn and 1320 stapled. Baseline characteristics were similar. No significant differences were identified in anastomotic leakage, postoperative ileus, reoperation rate, surgical-site infection, LOS or death. The stapled group had a significantly shorter duration of surgery and fewer Clavien-Dindo grade I-II complications. In multivariable logistic regression analysis, ASA grade and BMI were found to be significantly associated with postoperative complications such as anastomotic leakage, postoperative ileus and reoperation rate. Conclusion: Handsewn and stapled ileocolic anastomoses for open right-sided colonic cancer resections are equally safe. Stapler use was associated with reduced duration of surgery and significantly fewer minor complications.

RESUMO

Allogeneic hematopoietic cell transplantation (HCT) offers the chance of cure for patients with non-transformed follicular lymphoma (FL), but is associated with the risk of non-relapse mortality (NRM). The aim of this study was to identify subgroups of FL patients who benefit from HCT. The European Society for Blood and Marrow Transplantation (EBMT) Minimum-Essential-A Data of 146 consecutive patients who received HCT for FL between 1998 and 2008 were extracted from the database of the German Registry 'DRST'. Diagnosis of FL was verified by contact with the reference pathologists. Estimated 1-, 2- and 5-year overall survivals (OS) were 67%, 60% and 53%, respectively. Day 100 NRM was 15%. Thirteen out of 33 patients (40%) with treatment-refractory disease (RD) at the time of transplantation survived long term. Univariate statistical analysis suggested limited chronic GvHD, donor age ⩽42 years and TBI-based conditioning in treatment refractory patients to correlate with favorable OS. Independent prognostic factors for OS were treatment-sensitive disease and limited chronic GvHD for the whole cohort, and additionally TBI-based conditioning for the treatment refractory subgroup. In contrast, patient age ⩾55 years had no impact on outcome. Thus, HCT for FL is associated with acceptable NRM, and offers a substantial chance of cure for patients with RD or advanced age. Donors ⩽42 years should be preferred if available.

RESUMO

BACKGROUND: Cytokines and their genes have been described to have an influence on incidence and prognosis in malignant, infectious and autoimmune disease. We previously described the impact of cytokine production on prognosis in paediatric standard-risk acute lymphoblastic leukaemia (ALL). PROCEDURE: In this study, we investigated the influence of cytokine gene polymorphisms (TNFα, TGFß, IL10 and IFNγ) on frequency, risk group and prognosis in 95 paediatric ALL-patients. We further report on intracellular production of these cytokines in T-cells. RESULTS: IL10 high-producer-haplotypes were reduced in ALL-patients compared with healthy controls and resulted in a reduced relapse rate compared with low-producer haplotypes. TGFß high-producer-haplotypes were correlated with a high initial blast-count (codon 25: G/G) and were elevated in high-risk ALL-patients (codon 10: T/T). IL10 was positively and IFNγ-production was negatively correlated with initial blast-count. At diagnosis the expression of TNFα and IFNγ was reduced in patients compared with healthy controls. This was more pronounced in high-risk and in T-ALL-patients. CONCLUSION: We conclude that gene-polymorphisms of the regulatory/anti-inflammatory cytokines, TGFß and IL10, but not of the pro-inflammatory cytokines, IFNγ and TNFα, have an impact on prognosis and risk-group of ALL. However, the reduced capacity to produce pro-inflammatory cytokines at diagnosis may serve as another important, functional risk factor. These data may help in further risk stratification and adaptation of therapy-intensity in paediatric patients with ALL.

RESUMO

BACKGROUND: Kinase inhibitors targeting the BRAF V600 mutation have become standard in the treatment of metastatic melanoma. Albeit in wide clinical use, the patterns associated with therapy outcome are not fully elucidated. The present study was aimed to identify predictive factors of therapy response and survival under the BRAF inhibitor vemurafenib. PATIENTS AND METHODS: This multicenter retrospective study analyzed patient, tumor, and pretreatment characteristics collected in BRAF V600-mutated stage IV melanoma patients before single-agent therapy with the BRAF inhibitor vemurafenib. RESULTS: A total of 300 patients from 14 centers were included into this study with a median follow-up time of 13.0 months. Median progression-free survival (PFS) was 5.1 months; median overall survival (OS) was 7.6 months. Best response under vemurafenib was associated with serum lactate dehydrogenase (LDH; ≤ versus >upper normal limit; P = 0.0000001), Eastern Cooperative Oncology Group (ECOG) overall performance status (OPS) (0 versus ≥ 1; P = 0.00089), and BRAF mutation subtype (V600E versus V600K; P = 0.016). Multivariate analysis identified ECOG OPS ≥ 1 [hazard ratio (HR) = 1.88; P = 0.00005], immunotherapy pretreatment (HR = 0.53; P = 0.0067), elevated serum LDH (HR = 1.45; P = 0.012), age >55 years (HR = 0.72; P = 0.019), and chemotherapy pretreatment (HR = 1.39; P = 0.036) as independent predictors of PFS. For OS, elevated serum LDH (HR = 1.99; P = 0.00012), ECOG OPS ≥ 1 (HR = 1.90; P = 0.00063), age >55 years (HR = 0.65; P = 0.011), kinase inhibitor pretreatment (HR = 1.86; P = 0.014), immunotherapy pretreatment (HR = 0.57; P = 0.025), chemotherapy pretreatment (HR = 2.17; P = 0.039), and male gender (HR = 0.70; 95% confidence interval 0.50-0.98; P = 0.039) were found as predictors. CONCLUSION: Our data demonstrate that the type of pretreatment strongly influences the outcome of vemurafenib therapy, with a precedent immunotherapy showing a positive, and a prior chemotherapy and kinase inhibitors showing a negative impact on survival, respectively. Moreover, we show that the patient's OPS, serum LDH, age, and gender independently impact vemurafenib therapy outcome. These findings should be taken into account for the future design of therapy sequencing in BRAF V600 mutation-positive melanoma patients.

RESUMO

BACKGROUND: Hypophosphatasia (HP) is an inborn error of bone metabolism characterized by a genetic defect in the gene encoding the tissue-nonspecific alkaline phosphatase (TNSALP). There is a lack of knowledge as to how the variability and clinical severity of the HP phenotype (especially pain and walking impairment) are related to metabolic disturbances or impairments, subsequent to the molecular defect. METHODS: We analyzed the changes in clinical symptoms and the prostaglandin (PG) metabolism in response to treatment with non-steroidal anti-inflammatory drugs (NSAIDs) in six children affected by childhood HP. In addition, by exposing HP fibroblasts to pyridoxal phosphate and/or calcium pyrophosphate in vitro, we analyzed whether the alterations in PG levels are sequelae related to the metabolic defect. RESULTS: Childhood HP patients, who often complain about pain in the lower limbs without evident fractures, have systemic hyperprostaglandinism. Symptomatic anti-inflammatory treatment with NSAIDs significantly improved pain-associated physical impairment. Calcium pyrophosphate, but not pyridoxal phosphate, induced cyclooxygenase-2 (COX-2) gene expression and PG production in HP and normal fibroblasts in vitro. CONCLUSION: Clinical features of childhood HP related to pain in the lower legs may be, at least in part, sequelae related to elevated PG levels, secondary to the primary metabolic defect. Consequently, NSAID treatment does improve the clinical features of childhood HP.

RESUMO

High levels of factor VIII (FVIII) but not von Willebrand factor (vWF) are known to increase the risk for venous thromboembolism. Whether high FVIII levels originate from hereditary defects or from acquired conditions remains unanswered. The objective of our study was to investigate whether there is evidence for familial clustering of elevated FVIII levels in families in which >/=1 member has been affected by a thromboembolic event and had reproducibly high FVIII levels. We investigated FVIII levels in 361 patients with previous venous thromboembolism. FVIII levels were measured by a chromogenic assay; the cutoff value was defined as the 98th percentile of FVIII plasma levels of 266 blood donors. vWF levels were determined by an enzyme immunoassay. After exclusion of known causes of FVIII elevation, such as the acute thrombotic event itself; inflammation; malignancy; liver, renal, or vascular disease; surgery; or pregnancy, we included 17 patients with unexplained, reproducibly high FVIII levels. The investigation was also extended to these patients' relatives. Multiple regressive analysis of blood donors and asymptomatic family members showed that the affiliation with a family in which 1 member suffered from venous thromboembolism and had reproducibly high FVIII levels is the second most important predictor for FVIII levels. Familial clustering was analyzed by the Houwing-Duistermaat familial aggregation test. After adjustment for the influence of age, sex, blood group, and vWF, FVIII levels were significantly (P:=0.038) clustered within families. In conclusion, FVIII levels seem to be familially determined in families in which a member showed high FVIII levels after previous venous thromboembolism.

RESUMO

Lactate dehydrogenase (LDH) and 6-phosphogluconate dehydrogenase (6-PGDH) activities were measured in lobular areas expanding between 3 portal tracts and an efferent central vein in the livers of male Wistar rats, using a Lowry technique. The maximum of LDH activity was found in a nearly uniform broad area in the lobular periphery. From that area values decreased along periportal/septal-->perivenous gradients, but only slightly within that area along the periportal-->septal axis of the vascular septum. Maximum values of 6-PGDH activity were present in an intermediate area close to the central vein demonstrating a rather inhomogeneous distribution pattern without a clear definition of zonal limits. Our data on the distribution pattern of LDH are in agreement with the concept of the metabolic lobulus and are supported by a recent evaluation of the vascular architecture in rat liver. The lobular distribution pattern of 6-PGDH cannot be interpreted without doubt in accordance with that concept.

RESUMO

OBJECTIVE: Evaluation of long-term results of correction of high myopia by implantation of a biconcave Worst-Fechner minus power iris-claw lens into phakic eyes. METHODS: One hundred and twenty-seven eyes of 70 patients were implanted with the phakic IOL between November 1986 and November 1991. The mean preoperative spherical equivalent refraction was -14.29 +/- 5.77 D (range -5.00 to -31.75 D). The total population decreased from 127 to 68 eyes (53.5%) at the 8-year examination. By this time, 26 of the 70 patients (37%) had been lost to follow-up for unknown reasons. Corneal endothelial density was estimated by comparing the image gained by non-contact specular microscopy with a graduated reticule (Karickhoff method). RESULTS: At the 6-month examination, mean deviation of achieved from calculated refractive correction was +0.52 +/- 1.46 D (range -2.25 to +6.50 D). Seventy-seven eyes (62.1%) deviated 1.00 D or less, and 15 eyes (12.1%) deviated by more than 2.00 D from the calculated correction. A refractive outcome of +/- 1.00 D was attempted in 68 eyes (54% of the 124 eyes) and was achieved in 51 eyes (75%). Mean spectacle-corrected visual acuity preoperatively was 0.54 +/- 0.27 (range 1.20 to 0.05). At the 6-month examination it was 0.73 +/- 0.3, and by the 8-year examination had decreased to 0.65 +/- 0.26. Statistical analysis of corneal endothelial cell density revealed a significant correlation of endothelial cell loss with age (> or = 45 years), anterior chamber depth (< or = 3.4 mm), and IOL power (> or = -11.00 D). Seventeen eyes (13.4%) had a decrease in endothelial cell density and projection to 8-year follow-up resulted in a decrease in 27% of eyes. Four eyes needed a penetrating keratoplasty. CONCLUSION: Implantation of a biconcave Worst-Fechner lens into a phakic eye effectively corrected high myopia with a stable refractive outcome, but 13.4% of implanted eyes suffered significant progressive reduction of endothelial cell density. This style lens is no longer in clinical use.

RESUMO

In a family study involving 83 probands with periodic catatonia a subtype of DSM IIIR schizophrenia, we reported an age-specific morbidity risk of 26.9% in first-degree relatives with homotypical psychoses and genetic anticipation indicating a possible major gene effect. Paternal transmission was associated with a trend for a younger age at onset in probands compared to that observed in the case of maternal transmission (P = 0.099). If this can be confirmed in a larger sample and then replicated, there would be evidence for the occurrence of a parent-of-origin effect. Such an observation may indicate that a paternally imprinted locus acts on periodic catatonia. Among the non-genetic mechanisms that may modify the penetrance of the disease, paternal affection did lead to a decrease in male offspring (P = 0.007) and maternal affection showed an increased frequency of non-affected male offspring (P = 0.021). We therefore propose that parent-of-origin effects as well as prenatal mortality and psychosocial factors need further investigation in the periodic catatonia subtype of schizophrenia.

RESUMO

In a family study involving 139 probands with chronic DSM-III-R schizophrenia, catatonic type, 83 probands met the criteria for periodic catatonia and 56 probands those for systematic catatonia according to Leonhard. In the systematic catatonias, we found a low morbidity risk of 4.6% in first-degree relatives, an early age at first hospitalization and a high prevalence of affected males. In the light of our recent report of an association between maternal gestational infection and systematic schizophrenia, male fetuses exposed to midgestational infection seem to be particularly at risk of developing systematic catatonia. Periodic catatonia with a family morbidity risk of 26.9% affected both genders with equal frequency and showed no age-at-onset differences between the genders. We found a moderate inverse relationship between early-onset probands and an increased risk in relatives of 24.1% compared to 17.8% in late-onset probands. Our findings substantiate the hypothesis that periodic catatonia is a clinically homogenous disorder with a major gene effect and an age at onset which is to a large extent genetically determined.

RESUMO

BACKGROUND: Recently, we have demonstrated that the probability of postoperative vomiting (PV) following ENT surgery with inhalational anaesthetics can be predicted using a risk score. This score is based on gender, age, smoking status, history of motion sickness or postoperative nausea and vomiting and the duration of anaesthesia. Therefore, it is of interest whether this score is also accurate in predicting PV in patients undergoing different types of surgery. METHODS: Inpatients scheduled for bone, vascular, general or eye surgery were included in a prospective survey for PV over 24 h. Data of 1091 patients were analyzed, of which 542 were used for the validation of the previously constructed risk score (Score I). The data of the remaining 549 patients were used to evaluate the risk factors that contribute to PV in this setting and to develop a new score (Score II). The discriminating power of both scores to predict PV was tested in the validation set (n=542) and compared by calculating the area under the receiver operating characteristic (ROC) curves. RESULTS: The area under the ROC curve of Score I was 0.77 (SD 0.024). Risk factors for PV in the evaluation set were female gender, young age, history of motion sickness or postoperative nausea and vomiting and the type of surgery. The area under the curve of Score II was 0.75 (SD 0.026) and was not significantly different from Score I (P=0.57). CONCLUSION: Score I was accurate in predicting PV in patients after most types of surgery with volatile anaesthetics, which suggests that this score might be useful for other centres as well.

RESUMO

BACKGROUND: The aim of this study was to identify factors most relevant for postoperative vomiting (PV) and to develop a risk score to predict the probability of PV. METHODS: Adult inpatients scheduled for elective ear, nose and throat (ENT) surgery under general anaesthesia were offered to participate in a prospective study for PV over 24 h. No prophylactic antiemetics were used. The data of 1137 patients were randomized and split into an evaluation set (n=553) and a validation set (n=584). The evaluation set was subjected to logistic regression analysis to quantify the relative impact of anaesthetic, surgical and individual factors and to develop a risk score. The score was then tested by applying it to the validation set. The area under a receiver operation characteristic (ROC) curve was calculated and the predicted and actual incidences of patients were correlated. RESULTS: In the evaluation set, patient-related factors (female gender, young age, non-smoking, history of PV or motion sickness) and a high duration of anaesthesia were independent risk factors for PV. The probability of PV could be estimated from the equation: PV=1/(1+exp(-z)) where z=1.28 (gender)-0.029 (age)-0.74 x (smoking)+0.63 x (history of PV or motion sickness)+0.26 x (duration)-0.92. In the validation set this score achieved an area under the ROC-curve of 0.78 and the actual incidence correlated strongly with the predicted risks (R2=0.93, P<0.001). CONCLUSION: The data suggest that the probability of PV following ENT surgery under inhalational anaesthesia with low-dose opioids can be predicted by a score mainly based upon patient-related risk factors.

RESUMO

UNLABELLED: Diagnosis of Lyme arthritis (LA) in children and adolescents may be difficult due to non-specific clinical manifestations and unreliable serological tests for antibodies to Borrelia burgdorferi. In a national prospective study, 186 children with arthritis were examined in whom the attending physicians had considered the diagnosis of LA. Ultimately, LA was confirmed in 87 patients and these were compared with the remaining 99 children in whom arthritis was attributable to other causes. In comparison to patients with other causes of arthritis, patients with LA had a higher frequency of episodic arthritis and initial knee joint arthritis, reported tick bites more frequently, were older, had a lower frequency of initial arthralgias, and there were fewer large joints involved. A score was developed in a group of these patients and tested in a second group. It enabled patients with LA to be distinguished from those with other causes of arthritis: within a range from 12 to -7 points, a score of 2.5 or less excluded LA whereas 6 or more points were highly indicative of LA. If only those children with a score result between 2.5 and 6 had been tested for antibodies to B. burgdorferi, the number of tests would have been reduced by 63%. CONCLUSION: Careful analysis of clinical presentation and use of a clinical score may help in distinguishing LA from other causes of arthritis and thus reduce unnecessary and expensive testing and uninterpretable test results.

RESUMO

The role of drinking water fluoride content for prevention of osteoporosis remains controversial. Therefore, we analyzed the influence of drinking water fluoridation on the incidence of osteoporotic hip fractures and bone mineral density (BMD) in two different communities in eastern Germany: in Chemnitz, drinking water was fluoridated (1 mg/L) over a period of 30 years; in Halle, the water was not fluoridated. BMD was measured in healthy hospital employees aged 20-60 years (Halle: 214 women, 98 men; Chemnitz: 201 women, 43 men, respectively) using dual-energy X-ray absorptiometry. Hip fractures in patients > or = 35 years admitted to the local hospitals in the years 1987-1989 were collected from the clinic registers. There was no difference in age, anthropometric, hormonal, or lifestyle variables between the two groups. Mean fluoride exposure in Chemnitz was 25.2 +/- 7.3 years. No correlation was found between fluoride exposure and age-adjusted BMD. We found no significant difference in spinal or femoral BMD between subjects living in Halle and Chemnitz [lumbar spine: 0.997 +/- 0.129 (g/cm2) vs. 1.045 + 0.171 (g/cm2), p = 0.08, for men; 1.055 +/- 0.112 (g/cm2) vs. 1.046 +/- 0.117 (g/cm2), p = 0.47, for women]. The fracture incidence showed an exponential increase with aging in men and women with an incidence about 3.5 times higher for women. In Chemnitz, we calculated an age-adjusted annual incidence of 142.2 per 100,000 for women and 72.5 per 100,000 for men, respectively. In Halle, the incidences were 178.5 per 100,000 for women and 89.2 per 100,000 for men. There was a lower hip fracture incidence after the age of 85 in women in Chemnitz (1391 per 100,000 in Chemnitz vs. 1957 per 100,000) in Halle, p = 0.006). Using the age-adjusted incidences, significantly fewer hip fractures occurred in Chemnitz in both men and women. In conclusion, our study suggests that optimal drinking water fluoridation (1 mg/L), which is advocated for prevention of dental caries, does not influence peak bone density but may reduce the incidence of osteoporotic hip fractures in the very old.

RESUMO

The cumulative thrombotic risk of Factor V (FV) Leiden and oral contraceptives (OC) recommends screening for the mutation. Assuming that a family history of thrombosis increases the patient's likelihood of bearing FV Leiden, a selective rather than universal screening would be performed. We studied the utility of a family history of thrombosis for screening of FV Leiden before prescription of OC and, furthermore, the utility of screening even if oral contraception is favoured. 101 patients who had their first and single thromboembolic event while using OC were interviewed. 609 women without any history of thromboembolism recruited by gynecologists completed a standard questionnaire. 101 of these women, age-matched and currently using OC, were selected for a case-control study. Regarding patients with previous thromboembolism, a family history in a first-degree relative had a positive predictive value (PPV) of only 14% for FV Leiden. A PPV of 12% was calculated by investigating the 609 thrombosis-free women. Inherited FV Leiden (odds ratio = 4.9) and acquired risk factors (odds ratio = 10.1) were both found to be the most prominent, but independent additional risks. Nevertheless, FV Leiden carriers, both heterozygotes and homozygotes, did not suffer earlier from thromboembolism than patients without the mutation. In conclusion, family history is an unreliable criterion to detect FV Leiden carriers. Screening for factor V Leiden can be worthwhile even if the advantages of oral contraception are higher assessed than the thrombotic risk. Affected women knowing about their additional risk could contribute to the prevention of thrombosis in risk situations.


PIP: The cumulative thrombotic risk of Factor V Leiden (FVL) and oral contraceptive (OC) use raises the possibility of either selective or universal screening for this mutation before OCs are prescribed. Family history of venous thromboembolism as a criterion to detect FVL carriers was evaluated in a case-control study of 101 women from Bavaria, Germany, who had their first and single thromboembolic event while using OCs and 101 healthy age-matched OC users. A questionnaire was administered to a broader group of 609 OC users without a history of thromboembolism. Analysis of the 609 women revealed a 7.4% prevalence of FVL, but no association between this mutation and a family history of thromboembolism. Among women with a previous thromboembolism, a family history in a first-degree relative had a positive predictive value of only 14% for FVL. The sensitivity of family history was under 50%. 35% of cases compared with 8% of controls carried the FVL mutation. The most significant independent risk factors of thromboembolism were inherited FVL (odds ratio, 4.9) and acquired risk factors--i.e., surgery, leg fractures, distortions, confinement to bed for more than 1 week, or a restricted sitting position more than 6 hours in the 4 weeks before the index date (odds ratio, 10.1). Both heterozygote and homozygote FVL carriers did not suffer earlier from thromboembolism than patients without the mutation. These findings indicate that family history is not an effective predictor of FVL. However, even if the advantages of OC use are greater than the thrombotic risk, screening for FVL may be indicated to permit high-risk women to take preventive action.

RESUMO

A survival analysis was carried out based on the data of 190 male patients with alcoholic liver cirrhosis (Child A: 82.2%; Child B: 17.8%). Patients (mean age: 49.6 +/- 7.1 years) were examined during the period 1983-1990. Censoring in May 1993 was based on the recordings of the "Rentenversicherungsanstalten". There were no "drop-outs". During follow-up (mean: 4.2 years) 64 (33.7%) of the patients died. 13 potential prognostic variables were examined individually by drawing Kaplan-Meier curves and performing log-rank tests. Portal pressure, determined during hepatic vein catheterization as hepatic vein pressure gradient HVPG (P), size of esophageal varices, serum bilirubin, serum albumin, prothrombin time (Quick), thromboplastin time (PTT), cholinesterase (ChE) and Child scores were correlated to survival (p < 0.05), whereas age, gamma GT, IgA, drinking habits and additional diagnoses were not. A multivariate Cox regression analysis stepwise eliminated all but three variables: ChE, albumin and variceal size were included in the prognostic index PI of the final model. The usefulness of the model was tested by a cross validation method. No significant difference was found between estimated and observed survivorship functions. To compare the PI of the Cox model with Child's scores, ROC curves of sensitivity and specificity of predicting death within one, three and five years were constructed. Better prognostic efficiency was indicated for PI. Because ChE, albumin and the size of varices are determined as a routine in our clinic, we consider the construction of PI an advisable alternative to Child's classification.

RESUMO

In order to study the disappearance of human chorionic gonadotropin (hCG) in serum after surgery for ectopic pregnancy and to facilitate the postoperative follow-up of hCG decline serial hCG serum concentrations were analysed in 189 women with an uneventful postoperative course and in 4 patients with persistent trophoblast. A double logarithmic transformation of hCG concentrations resulted in a linear relationship of the individual hormonal decline versus the postoperative time (r2 = 0.990). The decrease of hCG levels was independent from the type of surgery or gestational age. The calculated half life of hCG steadily increased with rising time interval after surgery. A nomogram of hCG decrease was constructed using the regression lines of the individual sequential hormone concentrations. The nomogram enabled the detection of active residual trophoblast within one week after surgery before serious complications occur. Our scheme requires only three hCG tests to be performed before surgery, and on day 2 and 7.

RESUMO

To assess the clinical efficacy of adjunctive supragingival irrigation with buffered 0.3% acetylsalicylic acid (ASA), 60 patients with periodontitis receiving supportive periodontal therapy were randomly assigned to 1 of 3 home regimens: (1) 1x daily adjunctive supragingival irrigation with 300 ml water immediately followed by 200 ml of buffered 0.3% ASA; (2) 1x daily adjunctive supragingival irrigation with 500 ml water; or (3) normal oral hygiene alone. Clinical parameters were assessed at baseline and 6 months. Irrigator use was measured by timers built into the irrigator units. Results at 6 months showed that both supragingival irrigation with buffered 0.3% ASA and supragingival irrigation with water significantly reduced gingival index scores (median 0.1 and 0.35, respectively) and pocket probing depths (both median 0.26 mm) compared to the control group. In addition, irrigation with water resulted in a significant reduction in bleeding on probing (median 0.13), whereas irrigation with buffered 0.3% ASA had no significant effect on bleeding on probing compared to the control group. The clinical efficacy of irrigation with either ASA or water was found to be positively correlated to initial disease severity and irrigator use. Thus, frequent supragingival irrigation with either 0.3% ASA or water in addition to regular oral hygiene appears to be a beneficial adjunct to periodontal supportive therapy in patients with moderate to severe signs of periodontitis. However, the use of buffered 0.3% ASA as an irrigant does not seem to enhance the clinical efficacy of supragingival irrigation on periodontal health.

RESUMO

BACKGROUND: The controversely discussed effect of splenic loss and disturbances of the general state of health are to be reported by means of several check sheets. There is a control group for comparison and statistic evaluation. The results will be considered in relation to laboratory serum parameters. PATIENTS AND METHOD: 111 patients splenectomized for various reasons could be examined 3 to 17 years following surgery. We applied the depression check sheet by Beck, the Giessen complaint check sheet, and a specific splenectomy check sheet. The latter served to inquire an additional control group of statistic twins who underwent comparable upper abdominal surgery, but not splenectomy. Furthermore, 42 laboratory serum parameters were determined in every splenectomized patient. RESULTS: Compared to random tests with the Federal Republic's population, the Giessen complaint check sheet detected a more frequently disturbed state of health in "spleenless". An evaluation of the specific splenectomy check sheet detected an increased trend for infections after splenectomy (p = 0.0000001) compared to those after upper abdominal surgery. There was no statistical proof for other typical symptoms such as incompatibility with alcohol or vegetative dystonia. There was no significant anomaly in the 42 parameters measured. CONCLUSION: Every other splenectomized patient complained about frequent infections and, consequently, disturbed state of health (physical weakness, early exhaustion). These complaints did not correlate to the measured laboratory serum parameters.
