Accurate diagnosis of acute abdomen in FMF and acute appendicitis patients: how can we use procalcitonin?

This study was conducted to define the value of procalcitonin (PCT) levels in the differential diagnosis of abdominal familial Mediterranean fever (FMF) attacks from acute appendicitis. From October 2006 to January 2007, 28 FMF (12 males, 16 females) patients with acute abdominal attacks and 34 patients (18 males) with acute abdomen who underwent operation with the clinical diagnosis of acute appendicitis were consecutively enrolled in this study. FMF patients with concurrent infectious diseases were excluded. PCT values were measured by an immunofluorescent method using the B.R.A.H.M.S. PCT kit (B.R.A.H.M.S. Diagnostica, Berlin, Germany). Erythrocyte sedimentation rate (ESR), C-reactive proteins (CRP) and leucocyte levels were also noted. Mean disease duration in FMF patients was 9.6 ± 8.1 years (range 2–33 years) and all were on colchicine therapy with a mean colchicine dosage of 1.2 ± 0.4 mg/day. Among the operated patients, 5 were excluded: 3 patients had normal findings and 2 had intestinal perforation (PCT levels were 2.69 and 4.93 ng/ml, respectively) at operative and pathologic evaluation. There were no significant differences between the two groups with respect to gender and age (p was not significant (NS) for all). Acute phase reactants and PCT levels were increased in patients with FMF compared to patients with acute appendicitis (0.529[0.12 ± 0.96] vs 0.095 [0.01–0.80] p < 0.001, respectively). PCT levels higher than 0.5 ng/ml were found in 11% (3/28) of FMF patients compared to 62% (18/29) of acute appendicitis patients (p < 0.001). Our results suggest that PCT could be a useful test in the differentiation of abdominal FMF attacks from acute appendicitis, though it should not supplant more conventional investigations.     

Buerger's disease with multisystem involvement. A case report and a review of the literature

Buerger's disease is a recurrent inflammatory, nonatherosclerotic vasoocclusive disease, which typically affects small and medium-sized arteries, veins, and nerves of the upper and lower extremities. Systemic manifestations involving cerebral, mesenteric, and coronary arteries are exceptional. Moreover, multisystem involvement of 2 or more organs is extremely rare. The authors present a case of Buerger's disease in a patient who subsequently developed cerebral and bowel infarcts as well as cavernomatous transformation of the portal vein. Therefore, Buerger's disease, although rare, does have a chronic aggressive nature in some patients.     

The independent association of plateletcrit with long-term outcomes in patients undergoing primary percutaneous coronary intervention

Purpose

Platelets play a key role in the genesis of thrombosis. Plateletcrit (PCT) provides complete information on total platelet mass. The relationship between PCT values and long-term outcomes in patients with ST-segment elevation myocardial infarction (STEMI) who undergo primary angioplasty is not known. We sought to determine the effect of PCT values on the outcomes of primary angioplasty for STEMI.

Methods

Overall, 2572 consecutive STEMI patients (mean age, 56.6 ± 11.8 years) undergoing primary percutaneous coronary intervention were enrolled retrospectively into the present study. Plateletcrit at admission was measured as part of the automated complete blood count. Patients were classified into 2 groups: high PCT (> 0.237, n = 852) and nonhigh PCT (< 0.237, n = 1720). Clinical characteristics and in-hospital and long-term (median, 21 months) outcomes of primary angioplasty were analyzed.

Results

A higher in-hospital shock rate was observed among patients with high PCT values compared with those with nonhigh PCT values (6.5 vs 3.8%, respectively; P = .003). The long-term cardiovascular prognosis was worse for patients with high PCT values (Kaplan-Meier, log-rank test; P = .007). We used Cox proportional hazard models to examine the association between PCT and adverse clinical outcomes. High PCT values were also an independent predictor of cardiovascular mortality (hazard ratio, 1.85; 95% confidence interval, 1.061-3.22; P = .03).

Conclusion

High PCT values on admission are independently associated with long-term adverse outcomes in patients with STEMI who undergo primary angioplasty.     

Circulating Thrombopoietin in Clonal Versus Reactive Thrombocytosis

Introduction: The aim of this study is to assess circulating thrombopoietin concentrations in patients with both clonal and reactive thrombocytosis (RT), which are two distinct categories of extreme platelet production circumstances. Investigation of the thrombopoietin levels in clonal versus reactive thrombocytosis may help us to understand the interactions of this key regulatory cytokine and the conditions in which abnormally increased platelet formation exist.

Materials and methods: Thrombopoietin levels were measured in patients with platelet counts greater than 500 × 10³ μl^?1 The study population consisted of 21 patients with RT (13 with iron deficiency anemia, and 8 with rheumatoid arthritis), 24 patients with clonal thrombocytosis (six with essential thrombocytosis, three with myelofibrosis, eight with chronic myelogenous leukemia, and seven with polycythemia vera (PV)) and 16 healthy subjects were used as controls.

Results: The median plasma thrombopoietin concentration was 100.5 pg ml^?1 in patients with RT, 467pg ml^?1 in patients with clonal thrombocytosis and 62.65pgml^?1 in the control group. The thrombopoietin concentration was found to be higher in the patients with primary thrombocytosis when compared to the control group (p = 0.001), as well as in patients with RT (p = 0.002). However, there was no statistically significant difference between the patients with RT and the control group (p = 0.14). There was no correlation between thrombopoietin levels and the platelet counts in patients with clonal thrombocytosis, including essential thrombo- cythemia (ET).

Conclusion: Increased levels of thrombopoietin were found in patients with clonal thrombocytosis versus patients with RT and control subjects as well. Defective clearance of thrombopoietin by megakaryocytes and platelets due to a reduced number of thrombopoietin receptors may be the causative mechanism behind this. These results indicate that plasma thrombopoietin levels may be helpful in distinguishing between clonal and reactive thrombocytosis.

Left and right ventricular function is impaired in Behçet's disease

Objectives: Subclinical cardiac involvement may occur in patients with Behçet's disease (BD). The purpose of our study was to assess the noninvasive parameters of biventricular function derived from Doppler tissue imaging (DTI) of the tricuspid and mitral annular motion in BD. Methods: Twenty‐one patients with BD and 20 control subjects were enrolled in this study. All subjects were selected to exclude those with cardiovascular risk factors. Standard echocardiography and pulsed DTI were obtained in every patient. Results: Peak systolic (13.71 ± 2.09 vs 20.01 ± 1.57, P < 0.001), peak early diastolic (11.26 ± 2.52 vs 15.35 ± 2.06, P < 0.001) tricuspid annular velocities were significantly lower in patients than controls. Peak systolic (8.68 ± 1.4 vs 12.25 ± 1.7, P < 0.001), peak early diastolic (7.89 ± 1.07 vs 9.94 ± 1.12, P < 0.001), and peak end diastolic (8.30 ± 1.32 vs 9.23 ± 0.91, P = 0.013) lateral mitral annular velocities were significantly lower in patients than controls. Conclusions: We demonstrated that myocardial velocities, were affected in patients with BD. Therefore, we conclude that right and left ventricular function is impaired in patients with BD.

Vasculogenic Erectile Dysfunction and Metabolic Syndrome

IntroductionErectile dysfunction (ED), defined as the inability to achieve and/or maintain a penile erection sufficient for sexual intercourse, is a health problem affecting more than one-half of men between the age of 40 and 70 years.AimThe aim of the present study was to determine the potential factors affecting penile vascular flow and predictability of vascular flow in patients with ED.MethodsTotally 163 male patients between 29 and 82 years of age who were admitted to our outpatient clinic with complaints of ED were included. After a detailed medical history was obtained, all patients were asked to complete the International Index of Erectile Function (IIEF) questionnaire. Blood samples were obtained for measurements of serum cholesterol, triglycerides, and fasting blood glucose (FBG), and the body mass index (BMI) was calculated.Main Outcome MeasuresPenile color Doppler ultrasonography (PDU) was performed to evaluate flow patterns, Mann–Whitney U-test and Spearman correlation analyses were used to assess the relationship of PDU findings with hypertension, obesity (BMI ≥ 25 kg/m²), FBG, and cholesterol levels measurements.ResultsThe mean age, IIEF score, and BMI of the study population was 51.3 ± 12.1 years, 11.9 ± 6.1 and 28.5 ± 4.0 kg/m², respectively. When the vascular pathologies detected with PDU and the presence of risk factors were compared, no significant correlation was determined between arterial insufficiency and metabolic syndrome (MS), whereas there was a significant correlation between veno-occlusive dysfunction and MS.ConclusionThe prevalence of ED increases with advanced age and with the presence of a systemic disease. Basic evaluations may not always be sufficient for assessment of ED. In the presence of MS, the use of penile Doppler ultrasonography should be considered for the evaluation of penile vascular structures in ED patients. Koca O, Çal??kan S, Öztürk M?, Güne?

Serum creatine kinase enzyme levels in the early diagnosis of spermatic cord torsion

Delay in the diagnosis of spermatic cord torsion (SCT) is still a significant cause of testicular loss in children. The aim of this experimental study was to assess the diagnostic value of serum creatine kinase (CK) in the early period following SCT. Forty male rats were assigned randomly into five similar groups: group A, control; group B, sham, right testis exposed, manipulated, and blood sampling at 6th h; group C, right SCT, blood sampling at 2nd h; group D, right SCT, blood sampling at 4th h; and group E, right SCT, blood sampling at 6th h. CK and its isoenzymes were measured in the sera of all animals. All testes were removed and examined histopathologically. Significant increases in serum CK levels compared to control and sham groups were observed at 4 and 6 h following SCT. The major increase in CK was observed in the CK-MM isoenzyme fraction. Histologic pictures showed varying degrees of edema, vascular congestion, and hemorrhage in the testicular tissue, but no necrosis in any of the study groups. These results showed that serum CK levels in rats in the early period following SCT increase significantly before necrosis of testicular tissue. This may be of value as a diagnostic test, to corroborate findings from clinical studies.     

Spinal imbalance and decompensation problems in patients treated with Cotrel-Dubousset instrumentation

The basic principles of current idiopathic scoliosis treatment are three-dimensional correction and rigid fixation. Although it is accepted that Cotrel-Dubousset instrumentation (CDI) meets these goals, there is concern about the potential risk of trunk imbalance and spinal decompensation during the derotation manoeuvre. The results of 45 patients with idiopathic scoliosis treated with CDI between December 1988 and August 1992 were retrospectively analysed. Mean age was 14.3 years and mean follow-up period was 48.6 months. An average correction of 49.6% was achieved in the major curves. The best results were obtained in King type III curves, with a 69.4% correction. Spinal imbalance was evaluated by measuring lateral trunk shift (LT), shift of head (SH) and shift of stable vertebra (SS). Decompensation was measured by the increase in secondary curves. When all curve types were included, the average preoperative LT value of 1.96 vertebral units (VU) was brought down to 0.91 VU postoperatively, achieving a 55.9% correction. Fourteen patients had an SH value of zero preoperatively and remained balanced after instrumentation. Of the 41 remaining patients, 21 achieved an SH value of zero postoperatively. When all cases were included, the average preoperative SH value was 1.0 VU, which was corrected to 0.42 VU with CDI (69% correction). An average correction of SS of 75.5% was obtained, with the mean preoperative value of 0.73 VU being corrected to 0.19 VU. At the last follow-up visit, a secondary curve had formed above the major curve in one patient, and three patients had a junctional kyphosis. Loss of correction in the frontal plane correlated with loss of correction of LT. The rigid and semiflexible lumbar curves had a tendency to progress when they were not instrumented, especially in type II curves. Junctional kyphosis could be prevented when concave laminar claws were used in the thoraco-lumbar region. It was concluded that spinal decompensation and imbalance could be minimized with careful preoperative planning, avoidance of overcorrection and use of long instrumentation in double major curves.
