Vascular access site complications with the use of closure devices in patients treated with platelet glycoprotein IIb/IIIa inhibitors during rescue angioplasty.

The objective of this study was to evaluate the effectiveness of two different closure devices in patients undergoing rescue percutaneous coronary intervention (PCI) using IIb/IIIa inhibitors and to compare it with patients undergoing elective PCI. One hundred sixty-two patients undergoing rescue PCI treated with IIb/IIIa inhibitors underwent vascular access site closure (6 Fr Perclose, n = 92, or 6 Fr Angioseal, n = 70). Vascular complications were compared with a sex- and age-matched group (n = 100) of patients undergoing manual compression after sheath removal and a similar group of patients undergoing elective PCI (n = 196). The incidence of access site complications was not significantly different between the three groups undergoing rescue PCI and was not higher than in patient receiving GP IIb/IIIa inhibitors without fibrinolysis (RR = 0.95; 95% CI = 0.88-1.01). In patients undergoing rescue PCI and receiving IIb/IIIa inhibitors, closure devices allow early sheath removal and are associated with similar outcomes compared with manual compression and elective PCI regardless of the type of closure device used.     

Application of the ISTH bleeding score in hemophilia

Background

Hemophilia is an inherited bleeding disorder. With proper treatment and self-care, persons with hemophilia can maintain an active, productive lifestyle. Hemophilia can be mild, moderate, or severe, depending on the degree of plasma clotting factor deficiency. The aim of the study was to assess the utility of ISTH-BAT in diagnosis, determining severity of the bleeding condition in newly diagnosed and known hemophilia patients, compare the bleeding score (BS) in adult and pediatric groups and investigate its association with plasma factor levels.

Safety and efficacy of a 6 French perclose arterial suturing device following percutaneous coronary interventions: a pilot evaluation

BACKGROUND: Arterial access site management after percutaneous coronary intervention (PCI) is a matter of increasing importance in this era of potent antiplatelet pharmacotherapy. We evaluated the safety and efficacy of a 6 French (Fr) Perclose suturing device in achieving rapid hemostasis of the access site after PCI and thus improving patient comfort. METHODS: The 6 Fr Perclose (Prostar) device consists of a suture-based closure device delivered via introducer sheath designed for suturing of the arteriotomy puncture site. Over a 3-month period, the device was used in 48 consecutive PCI treated patients (age, 62 13 years; 70% male; 44% post myocardial infarction) and in-hospital groin complication rate was compared to 48 consecutive patients (age, 64 12 years; 64% male; 33% post myocardial infarction) who had manual compression hemostasis. RESULTS: Antiplatelet glycoprotein IIb/IIIa antagonists were used more frequently during and following the procedure in 58% of Perclose-treated patients versus 42% of the manual compression group (p = 0.019). Leg immobilization duration was 3 4 hours in all patients sutured by the device; in patients with manual compression, the sheath was removed at an average of 4.8 2.5 hours after termination of the PCI and an additional 6 hours of leg immobilization were subsequently required. No difference in overall major complication rate was found between groups (6.2% in suture-mediated patients versus 9.3% in manual compression group; p = 0.60). In 3 patients (6.2%) treated using the device, adjunctive manual compression was required in addition to groin suturing due to technical failure or residual oozing from the arteriotomy site. CONCLUSION: The 6 Fr Perclose device can be safely used to achieve rapid hemostasis and the device may hasten bed mobilization of PCI-treated patients despite frequent use of potent antiplatelet pharmacotherapy during coronary interventions.     

Feminizing testicular syndrome with multiple hamartomas and bilateral paratesticular leiomyomas

INTRODUCTION: Complete androgen insensitivity syndrome or testicular feminization syndrome (TF) is the most common form of male pseudohermaphrodism, caused by a failure of androgen receptor binding. Patient with male genotype 46 XY, has a female morphotype with well developed external sexual organs. EXEGESIS: - We report the case of a 29 year-old girl with a TF syndrome discovered during the exploration of a primary amenorrhoea. Bilateral orchidectomy was performed. The testis were immature; they showed bilateral leiomyoma of the tunica albuginea and multiple hamartomas on the right side. CONCLUSION: Benign tumors are developped in 80% of cases of TF and they are generally hamartomatous nodules of testis. Association of paratesticular leiomyoma to synchronous hamartoma has never been described, its histogenesis is discussed.     

Colchicine for large pericardial effusion

On the basis of our reported experience with colchicine for recurrent pericarditis, we administered colchicine to two patients with large pericardial effusions complicating idiopathic pericarditis. The first was a 26-year-old male who showed clinical deterioration following emergency pericardiocentesis and aspirin (3 g/day) for 10 days; the second was a 2-year-old girl who was unsuccessfully treated with aspirin (100 mg/kg/day) for 2 weeks, followed by corti-costeroids for 7 months. Administration of colchicine (1 mg/ day) instead of aspirin in the first case, and with a rapid tapering-off of the corticosteroids in the second case, led to complete regression of the pericardial effusion on echocardiography within 1 week and 1 month, respectively. Colchicine was discontinued after 1 month in the first patient and was continued for 6 months in the child. Neither has had a recurrence at 24 and 6 months of follow-up, respectively. No side effects of colchicine were observed. We conclude that colchicine may be effective in the treatment of large pericardial effusion when therapy with nonsteroidal anti-inflammatory drugs and/or corticosteroids fails.     

LetterEvidence of Association between FKBP1B and Thyroid Autoimmune Disorders in a Large Tunisian Family

FKBP1B belongs to immunophilins superfamily and functions as a cytosolic receptor protein of FK506. The role of FKBP1B in the immunosuppressive pathway of FK506 is well established. Previously, we reported a strong evidence of linkage between D2S171 microsatellite marker (located in vicinity of FKBP1B gene) and susceptibility to autoimmune thyroid diseases (AITDs). In this study, we report linkage disequilibrium between the dimorphism (C/T) in the 3′ untranslated region (3′ UTR) of FKBP1B gene and susceptibility to AITDs.

DNAs were extracted from a large Tunisian family affected with Graves' disease (GD) and Hashimoto's thyroiditis (HT) and analysed by PCR–RFLP using DraIII restriction enzyme. Our results showed an excess of transmission of the allele C from heterozygous parents to affected offspring (transmission disequilibrium test (TDT)=4.76; p=0.012). This suggests a linkage disequilibrium of 3′ UTR (C/T) SNP with AITDs. Moreover, The FBAT analysis gives a significant association with the C allele under the recessive model (χ²=5.50; p=0.018). These results support the involvement of FKBP1B gene in the genetic susceptibility to the AITDs development in the studied family.     

Chemical composition and larvicidal activity of several essential oils from Hypericum species from Tunisia

The chemical composition of the essential oils extracted from some Tunisian Hypericum species and their larvicidal activity against Culex pipiens larvae were evaluated. The chemical compositions of the essential oils from the aerial plant parts were analyzed using gas chromatography–mass spectrometry. One hundred and thirty-four compounds were identified, ranging between 85.1 and 95.4 % of the oil's composition. The components were monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, oxygenated sesquiterpenes, non-terpenic hydrocarbons, and others. The larvicidal activity of the essential oils was evaluated using a method recommended by WHO. Larvicidal tests revealed that essential oils from the Hypericum species have a significant larvicidal activity against C. pipiens, with LC₅₀ ranging between 102.82 and 194.70 ppm. The most powerful essential oils against these larvae were Hypericum tomentosum and Hypericum humifusum samples, followed by the essential oil of Hypericum perforatum.
