RESUMEN

AIM: To compare costs for three groups of people with type 2 diabetes, those at high risk of future cardiovascular disease, those without cardiovascular disease and those with established cardiovascular disease, and to also compare costs incurred by people with type 2 diabetes with an incident cardiovascular disease event with those who remain incident event-free over a 3-year period. METHODS: Data about people with type 2 diabetes in Scotland were obtained from the Scottish Care Information Diabetes registry. Data linkage was used to retrieve information on healthcare utilization, care home use and deaths. Productivity effects were estimated for those of non-pensionable age. We estimated costs over 12 months (prevalent cardiovascular disease) and 3 years from incident cardiovascular disease event. RESULTS: Mean annual cost per person with established cardiovascular disease was £6900, £3300 for a person at high risk of future cardiovascular disease, and £2500 for a person without cardiovascular disease and not at high risk. In year 1, the cost of an incident cardiovascular disease event was £16 700 compared with £2100 for people without an incident event. Over 2 years, the cumulative costs were £21 500 and £4200, and by year 3, £25 000 and £5900, respectively. CONCLUSIONS: Cardiovascular disease in people with type 2 diabetes places a significant financial burden on healthcare and the wider economy. Our results emphasize the financial consequences of cardiovascular disease prevention strategies.

RESUMEN

AIM: To investigate the effect of DAFNE and continuous subcutaneous insulin infusion in clinical practice. METHODS: Within NHS Lothian, continuous subcutaneous insulin infusion started in 2004 and DAFNE education began in 2006. We extracted anonymized data from the national database for all those aged > 18 years with type 1 diabetes having a Dose Adjustment For Normal Eating course or continuous subcutaneous insulin infusion start date (n = 4617). RESULTS: In total, 956 persons received DAFNE education, and 505 had received an insulin pump, 208 of whom had DAFNE education followed by insulin pump. Mean (SD) HbA1c before DAFNE education was 68 (15) mmol/mol (8.4% [1.4%]) and 66 (13) mmol/mol (8.2% [1.2%]) before continuous subcutaneous insulin infusion. In the year following DAFNE education, the mean fall in within-person HbA1c was 3.8 mmol/mol (95% CI 4.0 to 3.4; 0.3% [0.4% to 0.3%]). Those with the poorest control (HbA1c ≥ 85 mmol/mol [9.9%]) experienced the largest decline (15.7 mmol/mol [1.4%]). Those in the lowest HbA1c band at initiation (< 53 mmol/mmol [7.0%]) experienced a rise. In the year following continuous subcutaneous insulin infusion initiation there was a mean fall in within-person HbA1c of 6.6 mmol/mol (6.8 to 6.4; 0.6% [0.6% to 0.6%]). In those with the poorest control (HbA1c ≥ 85 mmol/mol [9.9%]), the mean fall in HbA1c was 22.2 mmol/mol (23 to 21; 2.0% [2.1% to 1.9%]). Continuous subcutaneous insulin infusion effectiveness was not different with or without DAFNE education. The effects of both interventions were sustained over 5 years. CONCLUSIONS: Both DAFNE education and insulin pump therapy had the greatest effect on HbA1c in those with higher baseline values. There was little difference to attained HbA1c when Dose Adjustment For Normal Eating education was introduced before insulin pump therapy.

RESUMEN

A total of 2475 animals from Germany, both captive and wild, were tested for antibodies against Francisella tularensis to obtain more knowledge about the presence of this pathogen in Germany. An indirect and a competitive ELISA served as screening methods, positive and inconclusive samples were confirmed by Western blot. Of the zoo animals sampled between 1992 and 2007 (n = 1122), three (0·3%) were seropositive. The seroconversion of a hippopotamus in Berlin Zoo was documented. From 1353 serum samples of wild foxes (Vulpes vulpes), raccoon dogs (Nyctereutes procyonoides) and wild boars (Sus scrofa), collected between 2005 and 2009 in the federal state of Brandenburg (surrounding Berlin), a total of 101 (7·5%) tested positive for antibodies to F. tularensis lipopolysaccharide. Our results indicate a higher seroprevalence of F. tularensis in wildlife in eastern Germany than commonly assumed. Furthermore, we found foxes and raccoon dogs to be biological indicators for tularaemia.

RESUMEN

BACKGROUND: Cervical Cancer is the second most common cancer among women. Nevertheless, similar tumours have only been rarely described in Great Apes. This report characterizes the pathological and molecular features of a metastatic endocervical adenocarcinoma in a Western lowland gorilla (Gorilla g. gorilla). METHODS: Necropsy and histopathology was performed to identify the cause of the disease in an cachectic 50-year-old western lowland gorilla. Immunohistochemistry for Ki67, oestrogen receptor alpha and ERBB2 was performed to characterize the tumor. In addition, Pan-herpesvirus and Pan-papillomavirus PCR were used to identify a possible viral cause. RESULTS: The endoccervical carcinoma showed a severe metastatic spread to the lung, brain and bone and was herpesvirus and papillomavirus-negative. Most tumor cells were ERBB2-positive, 15% of tumor cells were Ki67-positive and only few tumor cells had oestrogen receptor alpha expression. CONCLUSIONS: Histopathologically and immunohistochemically, the tumour had striking similarities to human endocervicial adenocarcinomas of the common type. However, PCR analysis failed to identify herpes- or papillomaviral DNA in the tumor at the time of necropsy, thus leaving the question for cause of the disease open.

RESUMEN

Acute hepatic vascular complications are rare. Acute portal vein thrombosis (PVT) and the Budd-Chiari syndrome (BSC) are the leading causes. Coagulopathy and local factors are present in up to 80% of cases. Diagnosis is established by colour-coded Doppler sonography, contrast-enhanced computed tomography or magnetic resonance imaging. Patients with acute PVT present with abdominal pain and disturbed intestinal motility. In the absence of cirrhosis anticoagulation with heparin is established followed by oral anticoagulation. In severe cases, surgical thrombectomy or transjugular thrombolysis with stent shunt may be necessary. Acute or fulminant BCS may require emergency liver transplantation or a transjugular intrahepatic portosystemic stent shunt, if patients present with acute liver failure. Milder cases receive anticoagulation for thrombolysis of occluded hepatic veins. Sinusoidal obstruction syndrome (SOS) is diagnosed after total body irradiation or chemotherapy, the term SOS replacing the former veno-occlusive disease. The treatment of congenital vascular malformations, complications in the setting of OLTX as well as patients with hepatic involvement of hereditary hemorrhagic telangiectasia requires significant expertise in a multidisciplinary approach.

RESUMEN

An oronasal fistula is described in a 53-year-old captive hippopotamus, the animal having shown a nasal discharge, consisting mainly of food particles, during and after feeding for at least 15 years. Necropsy of the emaciated animal revealed an oronasal fistula, measuring 4.5 x 3.5 cm, adjacent to the third left molar tooth, the first and second molars being missing. The fistula was thought to have been caused by an earlier necrotizing alveolitis and osteitis. There was no evidence of rhinitis or aspiration pneumonia. Unrelated findings consisted of a follicular thyroid adenoma and generalized muscle atrophy.

RESUMEN

Using high-resolution infrared oculography with digital recording and analysis techniques, we tested several types of eye movements in 19 schizophrenic patients and 11 normal controls. Abnormal slow pursuit eye movements, seen in about half of the patients, were characterized by erratic inaccuracies in position, velocity, and phase. Tracking errors were quantitatively assessed by their root mean square (RMS) error. Position RMS errors fell into two clearly separated groups, with 10 of 19 patients clustering about the normal controls and the remaining 9 having much higher errors than normal. Although several of these poor trackers had an excess of saccades or low pursuit gain, these abnormalities were not primarily responsible for the large erratic tracking errors. Saccades in response to unpredictable target jumps had normal latencies (reaction times) and velocities, but were more hypometric and variable in accuracy than those of controls. These saccadic abnormalities did not correlate with the patients' position RMS errors during slow pursuit.

RESUMEN

In the belief that it would prove a more effective stimulus for eliciting visual evoked potentials, a circular grating was designed so that the relationship between its bar width and visual acuity was held constant, and, therefore, the bars were equally well resolved across the visual field. Visual evoked potentials elicited by the onset presentation of the pattern were evaluated but found to be excessively variable owing to summation of different waveforms generated by equivalent stimulation of different parts of the visual field.

RESUMEN

Infrared oculographic recordings in three cases showed that voluntary nystagmus is composed of rapidly alternating small-amplitude saccades with normal velocity-amplitude characteristics. These bursts of reciprocating saccades are routinely associated with oscillopsia. This means in terms of oculomotor control theory that the brain stem mechanism mediating voluntary nystagmus must bypass the level in the oculomotor path where the saccadic corollary discharge (efferent copy) is initiated.

RESUMEN

Asian elephants are not self-sustaining in captivity. The main reasons for this phenomenon are a low birth rate, an aging population, and poor calf-rearing. Therefore, it is essential that reproductive rates had to be improved and there is need for rapid quantitative measures to monitor reproductive functions focussing on estrous detection and the prediction of the period of parturition. The objective of this study was to develop a method which combines headspace solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) for analyses of 5alpha-androst-2-en-17beta-ol and -17-one to prognose estrous and to predict the period of parturition. SPME was carried out with a CTC Combi Pal system. The course of the luteal phase-specific substance 5alpha-androst-2-en-17beta-ol and -17-one followed a cyclic pattern in which the follicular and luteal phases could be clearly distinguished (mean estrous cycle length, 15+/-1.4 weeks). Based on daily urine samples, estrous prognosis might be possibly based on the initial 5alpha-androst-2-en-17beta-o1 increase at the end of the follicular phase. Parturition prognosis was performed in three elephant cows based on the 5alpha-androst-2-en-17beta-o1 drop to baseline levels 5-4 days prior parturition. Experiments revealed that 5alpha-androst-3alpha-ol-17-one and probably 5alpha-androst-3alpha-ol-17beta-ol are generated from sulfate conjugates by a thermal process.

RESUMEN

Two patients, a 34-year-old woman and a 50-year-old woman, received tilorone HCl, an experimental antitumor drug. After taking the drug orally (total dose, 152 g), the first patient developed corneal subepithelial infiltrates and toxic retinopathy characterized by fine pigment mottling of the peripheral fundus and macula with mild arteriolar narrowing. Although visual acuity was 6/6 (20/20) throughout treatment, Goldmann perimetry showed marked peripheral constriction of the visual fields and results of an electroretinogram and an electro-oculogram were abnormal. After taking the drug orally (total dose, 189 g), the second patient developed corneal subepithelial infiltrates, severe bilateral arteriolar narrowing, and mild pigment mottling of the macula. ERG and EOG were moderately attenuated. Visual fields by Goldman perimetry were within normal limits. Tilorone HCl, like chloroquine, may be an antioxidant that affects the free radical scavenging mechanism of the retinal pigment epithelium. Extensive testing should be done on all patients taking tilorone HCl in order to detect the initial manifestations of retinopathy.

RESUMEN

BACKGROUND/AIMS: Hepatic hydrothorax is a complication of portal hypertension secondary to ascites. In this study, we investigated retrospectively the effects of the transjugular intrahepatic portosystemic shunt (TIPS) on hepatic hydrothorax refractory to diuretic treatment. METHODS: Forty patients (Child-Pugh class B, 24 patients; Child-Pugh class C, 16 patients) with hydrothorax refractory to diuretic treatment, pleurocenteses or pleurodesis were included. The TIPS implantation was successful in all patients, who were then followed for 16 +/- 14 months (range 1 day-54 months). RESULTS: TIPS reduced the portosystemic pressure gradient from 26 +/- 6 to 10 +/- 5 mmHg. In the 17 patients whom we followed for 12 months or longer, improvements were found for the Child--Pugh score (8.6 +/- 1.8 v. 6.7 +/- 1.5), serum albumin concentration (3.1 +/- 0.5 v. 3.6 +/- 0.5 g/l), and urinary sodium excretion (22 +/- 29 v. 89 +/- 43 mmol/24 h) (P< 0.05). Two patients developed severe hepatic encephalopathy requiring shunt occlusion. Hydrothorax improved in 82% of patients and resolved in 71% of patients. Fifty per cent of patients developed shunt insufficiency within 7 +/- 9 months, contributing to a probability of relapse-free 1-year survival of 35%. In these patients, shunt revision resulted in a secondary response rate of 82.3%. The 1-year survival was 64%. Both hydrothorax response and survival showed a significant inverse correlation with age over 60 years (P< 0.01 and P< 0.003, respectively) but not with other biomedical variables. CONCLUSION: TIPS is effective for hydrothorax refractory to diuretic treatment and other standard interventions to bridge the time to transplantation. Patients older than 60 years have a poor response and short survival.

RESUMEN

This report of a pilot study examines 29 pairs of twins from a population-based registry on whom four domains of schizotypy have been measured: personal interview using the Structured Interview for Schizotypy, self-report questionnaire formed from eight published self-report scales, attentional battery of eight individual tests, and root mean square error on smooth pursuit eye tracking. Analyzing the twins as individuals revealed two independent dimensions of clinically rated schizotypy (positive symptom schizotypy and negative symptom schizotypy) and two independent dimensions of self-rated schizotypy (positive trait schizotypy and trait anhedonia). Positive symptom schizotypy was highly correlated with positive trait schizotypy, but not with attentional dysfunction or eye-tracking error. By contrast, negative symptom schizotypy was significantly related to trait anhedonia, attentional dysfunction, and eye-tracking error. Correlations in monozygotic and dizygotic twins suggested that genetic factors were important in all four domains of schizotypy. Except for eye-tracking error, the results are more consistent with a dimensional than a "disease" model of schizotypy. Replication of these results with a larger group of subjects is needed.

RESUMEN

In this study we compared the ultrasound findings of 203 hospitalized patients with a variety of reference methods: biopsy, computed tomography and laboratory liver function tests with the aim of defining their clinical relevance. The ultrasound findings were assignable to 3 groups: normal, descriptive and definitive. When ultrasound described a liver as normal, or showing "increased echogenicity" or "altered configuration", the figures of normal clinical reference methods were almost identical (i.e., 70% normal). When a definitive ultrasound diagnosis ("cirrhosis", "fatty liver" or "cardiac congestion") was made, the percentage of otherwise normal livers decreased to less than 20% and was 0% for cirrhosis and cardiac congestion. The positive predictive value for a single abnormal criterion in ultrasound was between 16% and 21%, while for a definitive diagnosis it was between 67% and 100%. Many of our patients, however, had additional risk factors for liver abnormalities, such as obesity, diabetes mellitus or chemotherapy for malignancies. These risk factors can induce morphological parenchymal alterations without blood test abnormalities and, although correctly diagnosed by ultrasound, elude other reference methods in patients without biopsy. In conclusion, the finding of a single abnormal criterion of liver abnormality in ultrasound should be treated with caution. Ultrasound diagnoses of "fatty liver", "cirrhosis", diagnosed by additional signs of portal hypertension, or "cardiac congestion", yield more information. A normal ultrasound does not exclude the presence of fatty liver or cirrhosis.

RESUMEN

BACKGROUND/AIMS: Patients with cirrhosis of the liver are prone to bacterial infections. Therapeutic interventions such as endoscopic sclerotherapy increase the risk of bacterial infections in these patients. Following insertion of a transjugular intrahepatic portosystemic shunt (TIPS), the incidence of severe bacterial infections was recently shown to be 20% after elective procedures. This finding suggests antibiotic prophylaxis with the TIPS procedure. Antibiotic prophylaxis using cefotiam or cefotaxime/ampicillin did not significantly reduce infectious complications. The aim of the present study was therefore to investigate the efficacy of two different doses of a long-acting cephalosporin in prevention of bacterial infection after TIPS. METHODOLOGY: Eighty-two patients with cirrhosis (age: 52 +/- 2 years) who underwent elective TIPS were randomized to receive a single i.v. dose of either 1 g or 2 g Ceftriaxone 1 hour before the intervention. Patients with evidence of or suspected infections and patients on antibiotic therapy within 7 days prior to TIPS were excluded. Body temperature was monitored t.i.d. for 1 week and white blood count (WBC) and C-reactive protein (CRP) were determined before TIPS and 1 day and 1 week after TIPS. RESULTS: Only 2 of 82 patients (2.6%) showed signs of infection following TIPS insertion: One of 40 patients receiving 1 g Ceftriaxone and 1 of 42 patients receiving 2 g Ceftriaxone prior to TIPS developed temperature > 38.5 degrees C. In the latter patient this was due to pneumonia. This patient received antibiotic treatment with imipenem for 10 days. Temperature in the other patient normalized within 12 hours and he did not require antibiotic treatment. No significant differences in temperature, WBC and CRP between the different doses of Ceftriaxone were observed. CONCLUSIONS: Prophylactic treatment with Ceftriaxone reduces the reported incidence of bacterial infections after TIPS in patients with cirrhosis of the liver. Prophylaxis with 1 g Ceftriaxone seems as efficacious as 2 g.

RESUMEN

BACKGROUND/AIMS: In patients with cirrhosis, infection of the stomach with Helicobacter pylori may increase ammonia production and, consequently, the incidence of hepatic encephalopathy. To test this hypothesis a retrospective analysis was performed in patients with a transjugular intrahepatic portosystemic shunt. These patients are regarded to be ideal candidates for such a study since they have a high bioavailability of gut-derived ammonia and many of them develop spontaneous hepatic encephalopathy. METHODOLOGY: In 132 patients (Child-Pugh class A: 24%, B: 49%, C: 27%) with stable transjugular intrahepatic portosystemic shunt function for more than 3 months (mean follow-up: 15.5 +/- 10.8 months) the diagnosis of H. pylori infection was established by a specific and sensitive immunoblot assay for IgG- and IgA-antibodies. During follow-up, hepatic encephalopathy was assessed by clinical examination and a structured questionnaire. Venous plasma ammonia concentration was measured at the time of antibody determination (end of study period). RESULTS: Eighty-four patients (64%) had negative and 48 patients (36%) had positive immunoblots for H. pylori. The groups were comparable with respect to age, gender, etiology of cirrhosis, Child-Pugh class, follow-up after transjugular intrahepatic portosystemic shunt, and shunt function. The ammonia concentrations of the patients without (group 1) and with antibodies against H. pylori (group 2) were 73 +/- 27 and 69 +/- 28 mumol/L (mean +/- SD), respectively. Hepatic encephalopathy occurred in 23 of 84 patients (27%) of group 1 and in 11 of 48 patients (23%) of group 2. CONCLUSIONS: A positive immunoblot for H. pylori antibodies neither correlates with plasma ammonia concentration nor with the incidence of hepatic encephalopathy in patients with cirrhosis of the liver and portosystemic shunt.

RESUMEN

BACKGROUND: In the recent years several investigations focused on the diagnostic value of abdominal ultrasonography in pancreatic disorders. However, the diagnostic accuracy in these studies ranged between 40 and 90% probably related to variations in study design and other methodologic criteria. PATIENTS: We examined retrospectively 585 patients subdivided into six subgroups. 385 patients had a clinical question aimed at the pancreas and the remaining 200 functioned as screening patients. RESULTS: Using laboratory tests, CT, ERCP, surgery and autopsy as reference methods the positive predictive value for all pancreatic disorders was 85% with the best results for chronic pancreatitis (86% versus 77.5% for acute pancreatitis and 79.5% for malignant tumors). The prevalence of pancreatic disease in symptomatic patients was 28.6% versus only 2.5% in the screening groups. Therefore no significant differences could be detected in groups where the pancreas was not clearly visualized and groups with negative sonographic findings (4% false negative findings versus 1%, respectively). In groups with suspected pancreatic disease the negative predictive value was 86% which was independent of the visualization of the pancreas. CONCLUSION: In summary positive sonographic findings have a high predictive value for pancreatic disorders and negative results are not more reliable than missing visualization of the pancreas. The positive predictive value is independent from the kind of pancreatic disease and in screening examinations negative findings and findings without clearly visualization of the pancreas have both high negative predictive values.

RESUMEN

We studied the value of ultrasound and computed tomography in the preoperative diagnosis of abdominal diseases in 100 patients. Reference methods were the reports of surgery and pathology. A computed tomography or ultrasound diagnosis could be correct or false and was considered uncertain, if the main diagnosis was missed but computed tomography or ultrasound suspected pathology, which then could be clarified by other procedures. Overall, computed tomography was superior with 75 correct, 13 false and 12 uncertain diagnoses compared to ultrasound with 58 correct, 31 false and 11 uncertain diagnoses. Ultrasound often failed because obesity or gas impaired visibility. If only cases without technical problems of ultrasound were taken into account, diseases of liver, gallbladder, pancreas, kidney, the adrenal region and other abdominal masses were equally well diagnosed by ultrasound and computed tomography. As expected, the diagnostic value of both modalities was markedly reduced in diseases of the bile duct and the gastrointestinal tract. Because the study design required both, ultrasound and computed tomography, cases already clarified by ultrasound were not included. This fact might have further reduced the sensitivity of ultrasound in comparison to computed tomography. Furthermore, ultrasound was mostly one of the first diagnostic procedures performed right after the patient's admission with little information on anamnestic and clinical data. The information given prior to computed tomography was in general more detailed.

RESUMEN

Severe liver disease complicates pregnancy in only 0.1% of the cases. Viral hepatitis is the most common cause (40%). (Liver cirrhosis usually results in amenorrhea). Liver disease unique to pregnancy comprises "intrahepatic cholestasis of pregnancy" (Increased fetal risk), "acute fatty liver of pregnancy" (AFLP) and "HELLP-syndrome", both with high maternal and fetal risk when untreated. AFLP and HELLP-syndrome are diseases of the third trimester and show similar clinical signs of jaundice, coagulopathy and elevated liver enzymes. The immediate termination of pregnancy preferably by Caesarean section has been shown to improve both, maternal and fetal outcome. Imaging methods like ultrasound are invaluable in the differential diagnosis and detection of complications like subcapsular hematoma in the liver patients with HELLP-syndrome. Fulminant hepatic failure requires intensive care, liver transplantation is an additional therapeutic option. Recurrent AFLP has been reported recently.

RESUMEN

The African black rhinoceros (Diceros bicornis) has adapted to a low iron diet during evolution and is thus prone to iron overload in captivity, which is associated with a number of serious disorders. A S88T polymorphism in the HFE gene has been suggested as a potential genetic basis of increased iron uptake in the black rhinoceros, while the Indian rhinoceros is thought to be unaffected by iron overload in captivity. In the present study, the histopathology and distribution of iron accumulations in five black rhinoceroses with iron overload syndrome were characterized and compared with three Indian rhinoceroses (Rhinoceros unicornis) and one African white rhinoceros (Ceratotherium simum). At necropsy examination, iron storage in black rhinoceroses was not associated with gross lesions. Microscopically, the most consistent and highest degree of iron load was found in the spleen, liver, small intestine and lung. There was minimal fibrosis and single cell necrosis in the liver. Endocrine organs, lymph nodes, heart and kidney were less often and less markedly affected. Unexpectedly, Indian rhinoceroses also showed iron load in the spleen and smaller amounts in organs similar to the black rhinoceros except for in the heart, while the white rhinoceros had only minor detectable iron storage in intestine, liver and lung. Sequence analysis confirmed the HFE S88T polymorphism in black but not in Indian rhinoceroses. The results indicate that Indian rhinoceroses may also be affected by iron storage in captivity, although in a milder form than the black rhinoceros, and therefore challenge the relevance of the S88T polymorphism in the HFE gene of black rhinoceroses as the underlying cause for iron overload.
