Cord blood nesfatin-1 and apelin-36 levels in gestational diabetes mellitus

To assess maternal serum and cord blood apelin-36 and nesfatin-1 concentrations in pregnant women with and without gestational diabetes mellitus (GDM). Thirty pregnant women with GDM and 30 gestational age matched healthy pregnant subjects participated to the study. Maternal serum and cord blood nesfatin-1 and apelin-36 levels were measured with ELISA, at the time of birth. The relationships between maternal serum and cord blood nesfatin-1 and apelin-36 levels, anthropometric and metabolic parameters were also assessed. Maternal serum apelin-36 levels were found higher (13.5?±?8.3 vs. 9.6?±?5.9?ng/ml, P?=?0.001) and nesfatin-1 levels were found lower (5.5?±?8.1 vs. 8.1?±?23.9?ng/ml, P?=?0.001) in patients with GDM compared with control pregnant women. However, the cord blood apelin-36 levels (8.8?±?4.3 and 8.2?±?1.9?ng/ml, P?=?0.618) and nesfatin-1 levels (5.4?±?4.0 and 6.2?±?10.3?ng/ml, P?=?0.688) were similar in the GDM and control groups, respectively. Maternal serum apelin-36 and nesfatin-1 levels correlated positively with their respective cord blood levels. Maternal serum and cord blood apelin-36 levels correlated negatively with the gestational age and birth weight. Similarly maternal serum and cord blood nesfatin-1 levels correlated negatively with the gestational age, but there was no correlation with the birth weight. We did not find a correlation between maternal serum apelin-36 and nesfatin-1 levels, maternal age, BMI, fasting glucose, fasting insulin, and HOMA-IR. Also cord blood apelin-36 and nesfatin-1 levels did not correlate with the maternal age, BMI, HOMA-IR, cord blood glucose, and cord blood insulin levels. Our results indicate that apelin-36 concentrations increase and nesfatin-1 concentrations decrease in maternal serum of women with GDM.     

Unusual Traumatic Midthoracic Spondyloptosis and Its Surgical Management: Case Report

Posttraumatic spondyloptosis develops as a result of complete subluxation of the vertebral bodies and causes complete transection of the spinal cord. Severe trauma-related spondyloptosis of the upper-mid thoracic region is a rare form of spinal trauma. Traumatic midthoracic spondyloptosis is quite rare, and radiology plays an important role in the diagnosis and treatment of this condition. Surgical reconstruction and stabilization are required for early mobilization and rehabilitation of patients with this injury. Here, we report the clinical features, radiographic findings, and management of an unusual case of traumatic midthoracic spondyloptosis that showed complete spinal cord transection and was operated.     

Attention-deficit hyperactivity disorder in patients with premature ejaculation: a pilot study

Purpose

The etiology of both adult-type ADHD and PE is not completely understood, but the studies revealing common etiologic factors for both conditions suggest a high likelihood of coexistence. We aimed to find out the prevalence of ADHD among adult males with lifetime PE.

Methods

The patients with lifetime PE were included in the study. Both patients and controls were evaluated with the 10-item premature ejaculation index of Althof and Rosen for premature ejaculation, Wender Utah rating scale (WURS) and Conner’s adult ADHD rating scales (CAARS) for determining the presence of attention-deficit hyperactivity disorder syndrome.

Results

A total of 38 patients and 27 controls were included in the study. Patient and control groups were similar in terms of age and (p < 0.878), but different IELT (p < 0.001). ADHD was detected in 16 (42.1 %) of patients with PE, while ADHD symptoms were detected in only 1 (3.7 %) of control patients. Distribution of patients in the study group according to ADHD types was as follows: Type 1, Type 2, Type 3 in 2 (5.3 %), 4 (10.5 %), and 10 (26.3 %) patients, respectively.

Conclusions

ADHD is significantly more frequent among patients with PE than controls. The close relationships between these two diseases must be examined by prospective studies.     

Pathogen-driven decision for implant retention in the management of infected total knee prostheses

Purpose

In prosthetic joint infections (PJIs) of the knee, debridement with implant retention is associated with a high risk of recurrence.

Methods

A single-centre cohort study was performed with extensive analysis of the literature covering 1980–2012.

Results

In 21 patients (mean age 80.4 years, 19 immunosuppressed), in association with 1.5–three months of antibiotic treatment, an attempt was made to salvage the prosthesis by open (11 patients) or arthroscopic (ten patients) debridement. After a mean follow-up of seven years (range four–20 years), patients were in remission in seven cases (33 %). Remission was achieved in 0 % of all methicillin-resistant Staphylococcus aureus (MRSA) infections (zero/three), in 0 % (zero/three) of methicillin-resistant coagulase-negative staphylococcal infections, in 29 % (two/seven) of methicillin-sensitive S. aureus infections and in 75 % (three/four) of infections due to streptococci. The literature review focused on implant preserving approaches yielded 599 cases with an overall success rate of 47 % (284/599) and significantly more remissions in streptococcal vs staphylococcal knee PJIs (43/54 vs 144/324; p < 0.01, odds ratio 4.9, 95 % confidence interval 2.4–10.9).

Conclusions

In addition to established indications for explantation such as implant loosening, sinus tract or methicillin resistance, the decision for debridement and retention of knee PJIs should also depend on the pathogen. Implant preservation is futile with methicillin-resistant staphylococci, but seems to be a valid option for streptococcal PJIs.     

No need for broad-spectrum empirical antibiotic coverage after surgical drainage of orthopaedic implant infections

Purpose

Empirical broad-spectrum antibiotic treatment for orthopaedic implant infections after surgical lavage is common practice while awaiting microbiological results, but lacks evidence.

Methods

This was a single-centre cohort study from 1996 to 2010 with a follow-up of two years.

Results

We retrieved 342 implant infections and followed them up for a median of 3.5 years (61 recurred, 18 %). Infected implants were arthroplasties (n = 186), different plates, nails or other osteosyntheses. The main pathogens were S. aureus (163, 49 methicillin-resistant) and coagulase-negative staphylococci (60, 45 methicillin-resistant). Median duration of empirical antibiotic coverage after surgical drainage was three days before switching to targeted therapy. Vancomycin was the most frequent initial empirical agent (147), followed by intravenous co-amoxiclav (44). Most empirical antibiotic regimens (269, 79 %) proved sensitive to the causative pathogen, but were too broad in 111 episodes (32 %). Cephalosporins and penicillins were used only in 44 and ten cases, respectively, although they would have covered 59 % of causative pathogens identified later. Multivariate Cox regression analysis showed that neither susceptible antibiotic coverage (compared to non-susceptible; hazard ratio 0.7, 95 % confidence interval 0.4–1.2) nor broad-spectrum use (hazard ratio 1.1, 0.8–1.5) changed remission rates.

Conclusions

Provided that surgical drainage is performed, broad-spectrum antibiotic coverage does not enhance remission of orthopaedic implant infections during the first three days. If empirical agents are prescribed from the first day of infection, narrow-spectrum penicillins or cephalosporins can be considered to avoid unnecessary broad-spectrum antibiotic use.     

The safety and efficacy of high-dose daptomycin combined with rifampicin for the treatment of Gram-positive osteoarticular infections

Purpose

Treatment of Gram-positive osteoarticular infections requires an adequate surgical approach combined with intensive antimicrobial therapy. The aim of this study was to evaluate the safety and efficacy of a combined regimen of high-dose daptomycin and rifampicin, in patients with various types of Gram-positive osteoarticular infections.

Methods

This single centre, non-comparative, prospective study evaluated the safety and efficacy of a combined regimen of intravenous daptomycin (8 mg/kg/day) and oral rifampicin (600 mg/day) in patients with Gram-positive osteoarticular infections, with a minimal follow-up of one year. Creatine phosphokinase, transaminases, bilirubinaemia, and serum creatinine, were measured at baseline and regular intervals.

Results

The median daily doses of daptomycin and rifampicin, administered for a median duration of 21 (range, 10–122) days to 16 patients (median age, 63.5 years; 11 males, five females) presenting with staphylococcal (n = 15) or streptococcal (n = 1) osteoarticular infections, were 8.15 (range, 6.6–8.9) mg/kg/day and 600 (range, 600–900) mg/day, respectively. The combined regimen of daptomycin and rifampicin was well tolerated by all except one patient, without requiring treatment adjustment or discontinuation. One patient developed allergic responses probably due to rifampicin after 42 days. Fifteen (94 %) patients showed favourable clinical and microbiological outcomes.

Conclusions

The combined regimen of high-dose daptomycin and rifampicin was well tolerated and may provide a useful alternative to standard glycopeptide therapy for Gram-positive osteoarticular infections.
