Gallstones at chronic spontaneous urticaria patients: A retrospective clinical study

Chronic spontaneous urticaria (CSU) is a chronic, inflammatory skin disease can be triggered by many factors such as inflammatory process. To assess accompanying gallstone in CSU patients and to evaluate laboratory test results. We retrospectivelyscanned the files of the 108 patients with CSU who had been diagnosed CSU in September 2017–September 2019. Accompanied gallstone cases by detecting transabdominal ultrasound (TUS) or were 11 patients. Nine patients had also had cholecystectomy history. We seperated these 20 patients as Group A than the rest. WBC count is 9.38 ± 2.37 in Group A and 8.03 ± 2.04 in Group B. Platelet count was also differ between two groups significantly (Group A = 328.70 ± 85.62 × 10³/mm³ vs. Group B = 287.12 ± 72.77 × 10³/mm³). Neutrophil count was more in Group A (5.87 ± 1.65) than Group B (4.76 ± 1.75). Gallstone history of family was significantly higher in Group A (n = 12 positive/8 negative) than Group B. These findings were significant statistically p < .05. CSU can be associated with inflammation and gallstones. It is needed to perform further investigations to detect these relations and pathways.     

Regional push-out bond strength and coronal microleakage of Resilon after different light-curing methods

The purpose of this study was to assess the push-out bond strength and coronal microleakage of the Epiphany (Pentron Clinical Technologies, Wallingford, CT) + Resilon (Resilon Research LLC, Madison, CT) obturation system with respect to different photoactivation methods used. Roots of human maxillary central incisors (n = 60) were prepared with 0.06 taper nickel-titanum rotary files to size 30. After application of the Epiphany sealer, the roots were obturated with Resilon cones. The specimens were randomly assigned into three groups (n = 10/group) according to the light-curing unit (LCU) used from the coronal aspect: (1) quartz-tungsten-halogen/40 seconds, (2) light-emitting diode/20 seconds, and (3) plasma arc/6 seconds. Thereafter, 2-mm thick horizontal sections (n = 3) were obtained from each specimen from the coronal to apical direction and subjected to push-out test at a crosshead-speed of 1mm/min. Failure modes were assessed quantitatively under a stereomicroscope and morphologically under a scanning electron microscope. The remaining 30 roots were used for the dye-leakage assessments. Both the type of LCU and the level of sectioning had significant effects on bond strength. The following statistical ranking was obtained for bond strength values: quartz-tungsten-halogen > light-emitting diode > plasma arc. Coronal microleakage of specimens cured with the plasma arc was significantly greater than those of other groups (p < 0.05).     

Endovascular management of traumatic arterial emergencies: A single center retrospective study

Objectives: To present our experience in delivering endovascular therapies for emergent vascular traumas with various vascular structures. Methods: Between September 2013 and February 2018, patients who underwent endovascular intervention due to penetrating, blunt and iatrogenic arterial traumas were analyzed, retrospectively. Demographic data, trauma site, mechanism of injury, angiographic findings or arterial injury patterns, treatment methods, and outcomes were recorded. Results: A total of 30 patients were included. The mean age of patients was 39 years (range: 15-87 years). Arterial trauma locations were in the compressible area with a rate of 43％ (n=13) and in the noncompressed area with a rate of 57％ (n=17). Mechanisms of injuries were blunt [53％ (n=16)], penetrating [17％ (n=5)], and iatrogenic [30％ (n=9)]. The most common indication for endovascular treatment was blunt noncompressible injury (n=12). Methods used for treatment were stent-graft (46％, n=14) and coil embolization (54％, n=16). Immediate success was obtained in all procedures. The mean follow-up duration was 5 months (range: 1-12 months). Conclusions: Endovascular treatments performed in traumatic arterial emergencies are effective and minimally invasive with very low complication rates even in hemodynamically unstable patients.     

A Combination of Nifedipine and OctreotideTreatment in an HyperinsulinemicHypoglycemic Infant

Hyperinsulinemic hypoglycemia (HH) is the commonest cause of persistent hypoglycemia in the neonatal and infancy periods. Mutations in the ABCC8 and KCNJ11 genes, which encode subunits of the ATP-sensitive potassium channel in the pancreatic beta cell, are identified in approximately 50% of these patients. The first-line drug in the treatment of HH is diazoxide. Octreotide and glucagon can be used in patients who show no response to diazoxide. Nifedipine, a calcium-channel blocker, has been shown to be an effective treatment in a small number of patients with diazoxide-unresponsive HH. We report a HH patient with a homozygous ABCC8 mutation (p.W1339X) who underwent a near-total pancreatectomy at 2 months of age due to a lack of response to diazoxide and octreotide treatment. Severe hypoglycemic attacks continued following surgery, while the patient was being treated with octreotide. These attacks resolved when nifedipine was introduced. Whilst our patient responded well to nifedipine, the dosage could not be increased to 0.75 mg/kg/day due to development of hypotension, a reported side effect of this drug. Currently, our patient, now aged 4 years, is receiving a combination of nifedipine and octreotide treatment. He is under good control and shows no side effects. In conclusion, nifedipine treatment can be started in patients with HH who show a poor response to diazoxide and octreotide treatment.     

The validation of left atrial strain imaging for the assessment of diastolic functions in patients with ST-segment elevation myocardial infarction

Assessment of left ventricular filling pressure (LVFP) is crucial in patients with ST-segment elevation myocardial infarction (STEMI). Since current guideline recommended echocardiographic parameters have limited value, more comprehensive assessment methods are required in this patient subset.In this study, we aimed to investigate the clinical utility of left atrial reservoir strain (LARS) imaging in patients treated with primary percutaneous coronary intervention (pPCI). Patients who underwent successful pPCI were included. Left ventricular end-diastolic pressure (LVEDP) was measured invasively following pPCI. Left atrial strain imaging was performed following pPCI within 24 h of pPCI. Normal LARS value was accepted as above 23%. We prospectively enrolled 69 patients; there were 18 patients with LARS below 23% who were included into group 1 and rest of the study population included into group 2. There was no significant difference between groups in terms of comorbidities.Troponin and pro-BNP levels were significantly higher in group 1 (p: 0.036 and 0.047 respectively). Left atrial volume and tricuspid regurgitation velocity were similar between groups (p: 0.416 and p: 0.351 respectively). Septal tissue velocity was higher (p: 0.001) and Septal E/e’ ratio was lower (p: 0.004) in group 2. Left ventricular (LV) global longitudinal strain value was higher in group 1 which is consistent with observed lower ejection (LVEF) fraction in group 1 (p: 0.001 for LV strain and p: 0.001 for LVEF). Estimated mean LVFP was also higher in group 1 (p: 0.003).Correlation analyses revealed moderate correlation between LARS and LVEDP (r: ? 0.300). Our results indicate that left atrial strain imaging is a promising tool for the assessment of left atrial pressure in patients with STEMI.

     

Synthesis of some benzimidazole derivatives and their antibacterial and antifungal activities.

A number of new benzimidazole derivatives were synthesized by the reaction of benzimidazole with appropriate alkyl halides. The compounds synthesized were intensified by 1H-NMR, Fourier Transformation Infrared (FT-IR) and micro analysis. All new and related compounds studied in this work were screened for their in vitro antimicrobial activities against the standard strains: Enterococcus faecalis (ATCC 29212), Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and the yeasts Candida albicans and Candida tropicalis. Eleven of the compounds were found effective to inhibit the growth of Gram-positive bacteria (E. faecalis and S. aureus) at MIC values between 12.5-400 micrograms/ml. None of the compounds exhibited antimicrobial activity against Gram-negative bacteria (E. coli and P. aeruginosa) at the concentrations studied (6.25-800 micrograms/ml). All compounds (except compound 3) were significantly effective against C. tropicalis with MIC values of 6.25-400 micrograms/ml. Eight of the tested compounds showed an antifungal activity against C. albicans with a range of the MICs between 50 and 400 micrograms/ml.     

Legionnaire's disease: a nosocomial outbreak in Turkey

Six nosocomial cases of Legionella pneumophila occurred over a two-week period, with one further case being diagnosed retrospectively after 30 days. Strains isolated from the hospital water system were clonally related to a single sputum isolate. A sero-epidemiological investigation into legionella exposure amongst staff and inpatients was undertaken at the eight-year-old Inonu University Medical Centre in Turkey, which has 600 beds and central air conditioning. There is no disinfection programme for the hospital water system. A total of 500 serum samples (400 hospital staff and 100 inpatients) were screened for antibody to L. pneumophila by enzyme-linked immunosorbent assay (ELISA). Seroreactive cases were confirmed by a four-fold antibody rise in ELISA, a high indirect immunofluorescent assay (IFA) antibody titre or a positive urinary antigen test. ELISA showed that 24 (6%) of the 400 hospital staff and seven (7%) of the 100 inpatients had antibody titres higher than the cut-off value. ELISA-seroreactive cases were followed for two to four weeks. Of these subjects, seven (three patients and four staff) showed a four-fold rise in antibody titre by ELISA, six (three patients and three staff) had a high IFA titre, three patients with pneumonia had a positive urinary antigen test, and one of these patients also had a positive sputum culture. In addition, 22 water distribution systems were screened for the presence of L. pneumophila by culture. L. pneumophila was isolated from 15 sites. Pulsed-field gel electrophoresis typing indicated that all strains isolated from water systems were identical and clonally related to the strain isolated from sputum. Superheating and flushing of water systems were undertaken with legionella being re-isolated from four sites. Repeated superheating and flushing eliminated legionella completely. This study demonstrated that rapid detection of L. pneumophila and adequate superheating and flushing of water systems are effective for elimination and reduction of spread of this organism.
