Osteochondritis dissecans of the vertebral endplate of C5 with concomitant C4-C5 disc protrusion in a French Bulldog.

A 4-year-old French bulldog was presented with neck pain and left forelimb lameness. CT scan revealed a bony defect in the craniodorsal rim of the endplate of C5 with a concomitant disc protrusion leading to ventral spinal cord compression. Ventral slot at C4-C5 was performed to remove the protruding material and the fragment. Based on CT and histological findings, this bone defect was consistent with osteochondritis dissecans. Neck pain was absent immediately after the operation and the dog recovered without complication. Only a slight proprioceptive deficit of the left forelimb persisted during the 6-month of follow-up. Based on our search of the veterinary literature, this is the first published report of an osteochondritis dissecans of cervical endplate treated surgically.

Prevalence of diabetes and impaired fasting glucose in Poland--the NATPOL 2011 Study.

AIMS: The aim of the analysis was to assess the prevalence of diabetes and impaired fasting glucose in Poland. METHODS: A questionnaire survey on a representative sample of 2411 Polish adults, complemented by blood pressure, anthropometric and fasting plasma glucose measurements. The research was part of the national cross-sectional NATPOL 2011 Study. Diabetes was assessed as self-reported (diagnosed) or screened (fasting plasma glucose level ≥ 7 mmol/l, based on one blood draw). RESULTS: Total prevalence of diabetes in 2011 was 6.7% (95% CI 5.6-7.9); 6.4% (95% CI 5.0-8.0) in women and 7.0% (95% CI 5.4-8.8) in men and did not change from 2002 (6.8%, 95% CI 95% CI 5.8-7.9). Over one quarter of individuals with diabetes were not aware of having the condition. Obesity, arterial hypertension and male gender were strong predictors of screened diabetes. Total prevalence of impaired fasting glucose in the surveyed population was 15.6% (95% CI 14.0-17.2). CONCLUSIONS: The prevalence of diabetes in Poland is similar to that observed in other European populations and has not changed over the last decade. The fact that every fourth person with diabetes is unaware of the disease creates important opportunities for screening and detection of the disease.

Effects of metformin or an oral contraceptive containing cyproterone acetate on serum c-reactive protein, interleukin-6 and soluble vascular cell adhesion molecule-1 concentrations in women with polycystic ovary syndrome.

The aim of the present study was to evaluate the effects of commonly used treatment regimens such as metformin (MET) or an oral contraceptive pill (OC) containing ethynyloestradiol and cyproterone acetate (EE-CPA) on surrogate serum CVD risk factors and markers of endothelial dysfunction (CRP, IL-6, sVCAM) in women with PCOS.This study was conducted in a crossover design in order to compare the effects of 2 different treatment regimens in the same subject and has been registered under the number NCT01798875 in the ClinicalTrials.gov registry.42 women with PCOS (age range 18-36 years, median BMI 24.9) were randomly assigned to treatment with MET (850 mg bid) or EE-CPA containing OC for 4 months. After 2 months washout period, treatments were crossed over.Treatment with and OC increased significantly serum CRP concentrations (from 0.77 mg/l [95% CI: 0.70; 2.18] to 1.70 mg/l [95% CI: 1.65; 3.69], P<0.001). Treatment with MET slightly reduced serum CRP levels, but this difference did not reach statistical significance (P=0.08). 4 months treatment with MET or EE-CPA had no effect on serum IL-6 and sVCAM-1 concentrations (P>0.05).Treatment with EE-CPA containing OC for 4 months in women with PCOS significantly raises serum CRP. Since this rise was not accompanied by the increase in serum concentrations of IL-6, which is the most potent and effective stimulant of hepatic CRP production, we can speculate that this effect is caused by the liver first-pass effect of oral oestrogen administration. If this in turn can confer, cardiovascular risk among these women warrants further -studies.

Retrospective study of Mycoplasma gallisepticum meningoencephalitis in six turkey flocks in western France.

Mycoplasma gallisepticum (MG) meningoencephalitis was diagnosed in six turkey flocks, from 1998 to 2005, in the western part of France. Affected birds were 8-11 weeks old and all displayed neurological signs, especially torticollis, with more than half having concomitant respiratory signs. Microscopical examination of brain samples from birds in all six flocks revealed similar lesions of acute to subacute multifocal parenchymal necrosis, perivascular cuffing, leptomeningitis and vasculitis. Birds from four of the six affected flocks were seropositive for MG and in birds from four flocks MG DNA was detected by polymerase chain reaction performed on tracheal swabs or on samples of formalin-fixed and paraffin wax-embedded brain. To our knowledge, this is the first pathological description of naturally occurring cases of turkey MG meningoencephalitis in Europe.

Assessment of the quality of secondary ischemic stroke prevention in selected urban areas of Poland and Ukraine: the ASCEP study results.

UNLABELLED: The aim of this study was to assess the quality of secondary ischemic stroke (IS) prevention among subjects after IS from selected urban areas of Poland (Gdynia, G) and Ukraine (Lutsk, L). METHODS: The study was conducted on representative samples of post-IS patients from G and L who suffered from IS in the years 2000-2005. A questionnaire, anthropometric and blood pressure (BP) measurements and laboratory tests were performed. RESULTS: The data of 440 patients were collected. Only 47% in G and 58% in L (p < 0.05) had visited a neurologist within 6 months before the interview. Results of the prevalence and control of consecutive IS risk factors were estimated: (1) arterial hypertension (prevalence: 88% G, 92% L, p = 0.1; BP <140/90 mm Hg: 23% G, 16% L, p = 0.02); (2) hypercholesterolemia (prevalence: 90% G, 76% L, p < 0.05; total cholesterol <175 mg/dl: 11% G, 6% L, p = 0.05); (3) self-reported diabetes or glycemia >125 mg/dl: 22% G, 17% L, p = 0.08; (4) smoking: 26% men versus 16% women in G, 33% men versus 2% women in L, p < 0.05, and (5) self-reported atrial fibrillation: 28% G, 7% L, p < 0.05. Antiplatelet drugs or oral anticoagulants were taken by 51% G versus 45.5% L (not significant). CONCLUSIONS: The quality of secondary IS prevention is insufficient, and there is a need for complex educational interventions in patients, their families and medical staff. Our data also call for organizational changes in the health service both in Poland and Ukraine.

Microcystic meningioma in a dolphin (Delphinus delphis): immunohistochemical and ultrastructural study.

A wild common dolphin was found stranded on the French Atlantic coast. At necropsy, an intracranial grey- to tan-coloured mass (7 x 5 x 4 cm) was found at the right cerebellopontine angle, compressing the right cerebellar hemisphere, the brainstem and the occipital lobe of the right cerebral hemisphere. Microscopically, the tumour was composed of small lobules of polygonal to elongated neoplastic cells with multifocal areas of stellate and vacuolated cells. Neoplastic cells strongly expressed vimentin, S-100 protein and neuron-specific enolase. They were rarely positive for cytokeratin. Ultrastructurally, the neoplastic cells displayed all the diagnostic features of meningiomas and in some areas showed long cytoplasmic processes delimiting extracellular spaces. The immunohistochemical and ultrastructural features were consistent with the histopathological diagnosis of a microcystic meningioma. This is the first report of a meningioma in dolphins or in any other cetacean species.

Arterial hypertension in Poland in 2002.

Arterial hypertension represents a serious medical, social and economic problem in Poland. Owing to a small number of studies concerning HT epidemiology in Poland and large differences in methodology, it is difficult to make an objective verification of the changes regarding principal parameters in our country within the last decade. Important programme for the assessment of the situation in our country is NATPOL PLUS, carried out in the year 2002 on a representative sample of 3051 adult Polish residents aged between 18 and 93 years, using the current diagnostic criteria for arterial hypertension (blood pressure readings obtained at three separate visits in cases of newly detected HT, different cuff sizes for different arm circumference, age range 18-93 years, rejection of first measurement during initial screening visit). Prevalence of HT in Poland is 29%, awareness-67%, and effectiveness of treatment-12%. This means that while HT affects about 8.4 million adult Poles, only 1 million of them get effective treatment. Moreover, as much as 8.7 million Poles have high normal blood pressure and they should apply active prevention. The awareness, detection and control of hypertension is much worse in men than in women. A series of NATPOL studies indicated over the period 1994-2002 a significant and rapid decrease in the awareness of one's own blood pressure among the adult Polish population, especially in small towns and villages, among less educated people, and in males.

[Amyloid heart disease diagnosed with echocardiography]. / Amyloidoza serca rozpoznana echokardiograficznie.

A sixty years old woman with amyloid heart disease has been presented. Postural hypotension was the main symptom in this case. Pneumonia and the developing congestive heart failure was the cause of death. Only the last echocardiographic examination: hypertrophied interventicular septum with a peculiar speckled appearance of myocardium, together with low voltage electrocardiography made possible to confirm this diagnosis. It was shown in this case, how difficult it is to diagnose amyloid heart disease. Low ejection fraction together with diastolic abnormalities is usually a forecast of bad prognosis.

Biochemical part of the paper presents the structure, biosynthesis and degradation of the endothelins. Physiological chapter deals with endothelin-1 endocrine and mitogenic action as well as its impact on diuresis, natriuresis and cardiovascular system. In the clinical part of the article the role of endothelin-1 in essential hypertension, congestive heart failure and chronic renal failure is described.

[Pharmacotherapy of arterial hypertension and pharmacoeconomic aspects of hypotensive therapy in elderly patients in Poland]. / Leczenie farmakologiczne nadcisnienia tetniczego oraz wybrane aspekty farmakoekonomiczne terapii hipotensyjnej u chorych w starszym wieku w Polsce.

The aim of our study was to examine the use of pharmacological therapy and to evaluate the economical aspects of treating hypertension (HT) in elderly patients in Poland. Two hundred and sixty eight elderly persons (147 females, 121 males; mean age: 72.2 +/- 6.0 years) were selected from Polish population by stratified and cluster random sampling with quotas. BP measurement was performed 3 times every 2 minutes at respondents home. In the questionnaire, awareness of HT was assessed. Prevalence of hypertension among subjects aged 65 years and over by JNC VI criteria (SAP > or = 140 mm Hg, DAP > or = 90 mm Hg or hypotensive therapy) was 74%. Awareness of HT was equal to 61%. Eleven percent of all hypertensives were well controlled. Among hypertensives, 71% took prescribed antihypertensive drugs on a regular basis. Patients with HT were taking the following antihypertensive drugs: diuretics 16%, diuretics and reserpine 20%, beta-blockers 19%, ACE inhibitors 53%, calcium antagonists 30%, and other 3%. Newer drugs were prescribed in 7%, and multi-source (generic) products in 93%. The average cost of treatment with one drug was 147 PLN (37.5 USD) per year (newer drugs: 413 PLN; multi-source product 126 PLN). Assuming those data and number of elderly people in Poland (4.335 mln), we estimated that 3.208 mln of subjects have had hypertension according to JNC VI criteria. Only 1.957 mln of patients with HT have been detected and only 0.353 mln of hypertensives have been well controlled. The approximate global cost of antihypertensive drugs per year in elderly patients in Poland has been equal to 285 mln PLN (72.8 mln USD). In hypothetical situation with optimal (100%) detection and control of HT the global cost by the actual rate of regularity in taking drugs would increase to 569 mln PLN (145.3 mln USD). The prevalence of HT in elderly people in Poland is very high. In elderly hypertensives ACE inhibitors are used most often. More than 90% of prescribed drugs are multi-source products. An optimal improvement of HT detection and control would cause a two-fold augmentation of the costs of pharmacological therapy.

The influence of exercise on albumin excretion rate in borderline hypertensives and in offspring of hypertensive parents.

We investigated exercise induced urinary albumin excretion rate (UAE)(ex-UAE) in patients with borderline hypertension (BH) compared to normotensives with positive-PFH and negative-NFH family history of hypertension. The study population consisted of 20 young, non-obese males with BH defined according to WHO criteria and confirmed by 24 h ambulatory blood pressure (ABP) and 40 healthy matched normotensives (PFH = 20 and NFH = 20). Twenty-four hour UAE was assessed by day and night time urine collection. BH and normotensive subjects performed a 20 min ergometric graded exercise test. The relationship between 24 h UAE, 24 h ABP and 2-D-echocardiographic left ventricular mass index (LVMI) were examined. The three groups did not differ in 24 h UAE. Exercise induced a significant increase in UAE only in BH. Exercise induced UAE was greater in BH compared to normotensives: BH = 54.3(21-125), PFH = 37.6(13-62), NFH = 9.7(0-35)micrograms/min, data expressed as median (I quartile-III quartile). Pooled data from all three groups showed a positive correlation between ex-UAE and systolic BP (SBP) during night time (by multiple regression analysis). In conclusion, BH without other known cardiovascular risk factors, moderate dynamic exercise induced an excessive increase in UAE.

[Renin subgroups in borderline hypertension]. / Podgrupy reninowe w nadcisnieniu granicznym.

The study was carried out in 42 healthy men--control group and in 21 patients with borderline essential hypertension. It was found that the patients differ in hemodynamics from the control group. The group patients as a whole show significantly higher blood pressure, lower plasma volume and shorter total transit time compared with normotensive men. Division the patients on the renin subgroups revealed significant difference. High renin patients had hyperkinetic circulation. Patients with normal renin had significantly elevated total peripheral resistance. These results suggest that renin-angiotensin system no played an essential role in pathogenesis of borderline hypertension.

Renin-aldosterone regulation during upright posture in young men with mitral valve prolapse syndrome.

Previous studies have shown that symptom complex in patients with mitral valve prolapse syndrome (MVPS) may result from various forms of autonomic dysfunction. However, the interaction between adrenergic activity and renin release has not been studied. The purpose of this investigation was to assess changes in plasma renin activity (PRA) and plasma aldosterone in response to prolonged orthostatic stimulation in 19 young men with MVPS when compared to age- and sex-matched 20 control subjects. Heart rate was measured, and blood samples for PRA and aldosterone were obtained in the supine position and 90 min after assuming an upright position and slow walk. With posture the heart rate increase was greater in patients with MVPS in comparison with control subjects (19 +/- 9 vs. 12 +/- 8 beats per min, p < 0.05). Also an increase of PRA during upright activity was significantly greater in patients with MVPS (control 1.0 +/- 0.5 ng angiotensin I/mlxh, MVPS 1.8 +/- 1.7 ng angiotensin I/mlxh; p < 0.05). A significant correlation (r = 0.52, p < 0.05) was found between a rise of heart rate and PRA in patients with MVPS, but not in the control subjects. During prolonged upright activity aldosterone increased significantly in control subjects (at rest 74 +/- 41 pg/ml, with posture 98 +/- 68 pg/ml, p < 0.05) but did not change in patients with MVPS (at rest 64 +/- 29 pg/ml, with posture 67 +/- 26 pg/ml, NS).(ABSTRACT TRUNCATED AT 250 WORDS)

[Evaluation of hemodynamic changes in patients with primary arterial hypertension after treatment with a combination of pindolol and clopamide (Viskaldix)]. / Ocena zmian w dynamice krazenia u chorych z pierwotnym nadcisnieniem tetniczym po leczeniu trwalym polaczeniem pindololu z klopamidem (Viskaldix).

In 35 patients with mild essential hypertension the influence of 9 week Viskaldix therapy on hemodynamics was evaluated. Twelve of them underwent repeated hemodynamic examinations after mean 13 months treatment. Viskaldix therapy lowered total peripheral resistance --TPR and there was no significant influence on the heart rate, stroke volume, and cardiac output. It was demonstrated that decrease of total peripheral resistance after treatment with Viskaldix was directly proportional to the initial values of TPR.
