Isolation of <Emphasis Type="Italic">Borrelia burgdorferi</Emphasis> sensu lato from blood of adult patients with borrelial lymphocytoma,Lyme neuroborreliosis,Lyme arthritis and acrodermatitis chronica atrophicans

Background  

Reports on patients with European Lyme borreliosis in whom borreliae were isolated from the blood are rare and nearly exclusively limited to those with solitary or multiple erythema migrans. Here we report on patients with other manifestations of Lyme borreliosis in whom borreliae were isolated from their blood.     

Increased serum levels of S100B are related to the severity of cardiac dysfunction, renal insufficiency and major cardiac events in patients with chronic heart failure

Objective

To investigate the correlations between S100B and the severity of cardiac dysfunction, renal insufficiency (RI) and prognosis in chronic heart failure (CHF).

Method

Serum levels of S100B, TNF-α, high sensitivity CRP and NT-proBNP were determined in CHF patients with (n = 96) and without RI (n = 146). Patients with RI only (n = 62) and control subjects (n = 64) served for comparison. Patients were followed up for one year.

Results

S100B levels were higher in CHF patients with a further elevation in those with RI (P < 0.01). Serum S100B levels correlated with left ventricular ejection fraction, left ventricular end-diastolic volume and NT-proBNP in CHF patients, and eGFR in patients with RI (all P < 0.05). Increased S100B levels were associated with major cardiac events (MCE), and were independently associated with the presence of CHF (all P < 0.05).

Conclusion

Increased serum S100B levels were associated with the severity of cardiac dysfunction, RI and an adverse prognosis in CHF patients. It represents an independent risk factor for CHF.     

Treatment of severe to profound mixed hearing loss with the BAHA Cordelle II

GoalsEvaluation of the audiological outcome and subjective satisfaction of BAHA Cordelle II in the treatment of patients with severe to profound bilateral mixed hearing loss.Material and methodRetrospective study of 12 patients suffering a severe to profound bilateral sensorineural hearing loss, using pure tone audiometry (PTA), speech audiometry and subjective evaluation before and after the implantation of a BAHA Cordelle II (Cochlear^®).ResultsThe average gain in conversational frequencies (0.5 to 4 kHz) with BAHA in free field was 43, 51, 47 and 44 dB, respectively. We observed a GAP over closure in 10 of the 12 patients. Speech audiometry improved from 85% at 83 dB of maximum discrimination to 96% at 62 dB. The subjective evaluation questionnaires showed great satisfaction with a slight decrease in noisy or windy environments. The great majority of our patients used the BAHA device throughout the entire day.ConclusionsThe BAHA Cordelle II (Cochlear^®) is a good option in the treatment of severe to profound bilateral mixed hearing loss. Its best advantages are a low risk of labyrinthization, high result predictability, easy and step-by-step surgery, no need for general anaesthesia, and the GAP over closure in all frequencies. Active middle ear devices represent another alternative, but specific indications have not been defined yet because of low universal experience. When the intelligibility of the patient is poor, cochlear implantation should be considered.     

Borrelia burgdorferi sensu lato bacteremia in Slovenian children with solitary and multiple erythema migrans

To establish the frequency and characteristics of Borrelia burgdorferi sensu lato bacteremia in Slovenian children with solitary and multiple erythema migrans, 1164 patients were included in this prospective study. Bacteremia was established in 11.4% of all patients, 15.8% of patients with multiple erythema migrans, and in 7.6% of patients with solitary erythema migrans. Bacteremia can be detected in children, with untreated erythema migrans, up to 39 days after the onset of skin rash.     

Role of interleukin-8 and growth-regulated oncogene-alpha in the chemotactic migration of all-trans retinoic acid-treated promyelocytic leukemic cells toward alveolar epithelial cells

OBJECTIVE: Although all-trans retinoic acid (ATRA) can treat acute promyelocytic leukemia (APL), it also causes retinoic acid syndrome with presentations similar to acute respiratory distress syndrome. We investigated the role of interleukin (IL)-8 and growth-regulated oncogene (GRO)-alpha in the chemotactic transmigration of ATRA-treated NB4 (ATRA-NB4) APL cells toward A549 alveolar epithelial cells. DESIGN: An in vitro human cell culture study. SETTING: University hospital research laboratories. SUBJECTS: NB4 and A549 cells. INTERVENTIONS: NB4 and A549 cells were separately cultured with ATRA and/or dexamethasone for 1-3 days. NB4 or ATRA-NB4 cells were then placed in an upper insert and co-incubated with A549 cells or their conditioned medium located in a lower plate. MEASUREMENTS AND MAIN RESULTS: ATRA stimulated NB4 cells to transmigrate toward the A549 cells in a time- and dose-dependent manner. Replacement of A459 condition medium by its original medium abrogated this transmigration. Only A549 cells constitutively secreted GRO-alpha, and both A549 and NB4 cells constitutively secreted IL-8, which was enhanced by ATRA. Exogenous administration of IL-8 or GRO-alpha also promoted the ATRA-NB4 transmigration. The binding assay demonstrated that ATRA-NB4 cells bound IL-8, but not GRO-alpha, more avidly. Pretreatment with antibodies directed against IL-8 and GRO-alpha receptors reduced ATRA-NB4 transmigration by about 60%. Dexamethasone did not suppress their IL-8 secretion and transmigration in ATRA-NB4 cells, but when applied to A549 cells, IL-8 secretion was suppressed but not GRO-alpha secretion, and there was attenuation of ATRA-NB4 transmigration. CONCLUSIONS: IL-8 and GRO-alpha secreted from alveolar epithelial cells play an important role in the cell-cell interaction involved in the chemotactic transmigration of ATRA-treated APL cells toward alveolar epithelial cells.
