Cardiac reoperation by Carpentier bicaval femoral venous cannula: GATA experience

BACKGROUND: Division of the sternum is primarily a blind procedure in reoperation and carries an increased risk of injury for major cardiac structures in the presence of adhesions between the posterior table and the heart. METHODS: Two hundred patients were randomly divided into two groups. Cardiopulmonary bypass was established through the femoral artery and vein in group 1 (n = 100) patients before sternal reentry. Carpentier dual-stage femoral venous return cannula was used in all group 1 patients. Cardiopulmonary bypass was performed after sternal reentry in group 2 (n = 100) patients. RESULTS: Six severe cardiac injuries developed in group 2. Cardiopulmonary bypass time was 93 +/- 9 minutes in group 1 and 71 +/- 11 minutes in group 2 (p = 0.011), and the operation time was 155 +/- 23 minutes in group 1 and 185 +/- 32 minutes in group 2 (p = 0.024). Inotropic therapy was required in 52 patients in group 1 and 76 patients in group 2 (p = 0.032). Average chest drainage was 450 +/- 135 mL in group 1 and 850 +/- 250 mL in group 2 (p < 0.001). Average fresh whole blood transfusion was 3.3 +/- 1.2 U in group 1 and 5.8 +/- 0.9 U in group 2 (p = 0.033). Average intensive care unit stay was 2.2 +/- 1.3 days in group 1 and 4.5 +/- 2.3 days in group 2 (p = 0.025). Average hospital stay was 7.3 +/- 2.4 days in group 1 and 9.1 +/- 3.1 days for group 2 (p = 0.011). CONCLUSIONS: Cardiopulmonary bypass by bicaval Carpentier femoral venous cannula before resternotomy not only allows adequate cardiopulmonary bypass flow but also significantly reduces the risk of cardiac injury and catastrophic hemorrhage and allows safe reopening. Although this procedure increases cardiopulmonary bypass time, the operation time, bleeding, and blood transfusion requirement are significantly reduced.     

Dose-dependent neuroprotective effect of enoxaparin on cold-induced traumatic brain injury

Recent evidence exists that enoxaparin can reduce brain injury because of its anticoagulant activity. To investigate the potential therapeutic effect of enoxaparin on cold-induced traumatic brain injury, at 20 minutes after modeling, male BALB/c mouse models of cold-induced traumatic brain injury were intra-peritoneally administered 3 and 10 mg/kg enoxaparin or isotonic saline solution. Twenty-four hours later, enoxaparin at 10 mg/kg greatly reduced infarct volume, decreased cell apoptosis in the cortex and obviously increased serum level of total antioxidant status. By contrast, administration of enoxaparin at 3 mg/kg did not lead to these changes.These findings suggest that enoxaparin exhibits neuroprotective effect on cold-in-duced traumatic brain injury in a dose-dependent manner.     

Obesity: a possible risk factor for restless legs syndrome

Aim/Background: Restless legs syndrome (RLS) is a frequent neurological and sleep disorder. Metabolic disorders are known to be related to sleep disorders. We prospectively evaluated whether obesity and its possible cofactors were related to the presence of RLS.

Materials and Methods: The study included 143 obese and 94 non-obese individuals. Obese patients had a BMI of 30 and over, while non-obese patients had a BMI lower than 30. Patients with arthritis and pregnancy were excluded but not those with diabetes mellitus. Participants who met diagnostic criteria recommended by the International RLS Study Group were diagnosed as having RLS. Depression, anxiety, daytime sleepiness, insomnia and sleep quality were evaluated in detail.

Results: The mean age of obese patients was 40.52 years and that of non-obese patients was 39.76 years. The mean body mass index was 36.77 in the obese group and 25.71 in the non-obese group. The occurrence of depression, anxiety, sleep quality, and insomnia scores were significantly higher in obese individuals. The evaluations of daytime sleepiness, sleep efficiency and sleep latency were not significantly different between the groups.

Discussion: Although the presence of RLS was correlated with obesity and vascular risk factors at a significant level, it was also shown that depression, anxiety and insomnia were significantly frequent in obese patients (although not daytime sleepiness). Further studies are needed.     

Robotic-Assisted,Ultrasound-Guided Abdominal Cerclage During Pregnancy: Overcoming Minimally Invasive Surgery Limitations?

Herein, we report robotic abdominal cerclage placement under ultrasound guidance. The da Vinci Si system (Intuitive Surgical, Sunnyvale, CA) allows a simultaneous display of the operative field and transvaginal ultrasound images. Additionally, the vaginal ultrasound probe assisted in the manipulation of the uterus to improve visualization without placing excessive pressure on the gravid uterus. Ultrasound guidance improves needle placement accuracy and reduces potential for injuries.     

High Hip Center Reduces the Dynamic Hip Range of Motion and Increases the Hip Load: A Gait Analysis Study in Hip Arthroplasty Patients With Unilateral Developmental Dysplasia

BackgroundLong-term favorable clinical outcomes of anatomical or high hip center techniques in total hip arthroplasty (THA) are reported in patients with developmental dysplasia of the hip (DDH). However, there is little information about the effect of the hip center location on gait characteristics. The purpose of this study was to compare these surgical techniques with gait analysis, analyze the effect of the hip rotation center location on gait parameters, and discuss the possible problems that may arise.MethodsA total of 40 patients who underwent THA due to unilateral coxarthrosis secondary to Crowe type III-IV DDH and completed 5 years of follow-up were included in the study. Group 1 included 20 patients who underwent anatomical hip center reconstruction, while group 2 included 20 patients who underwent high hip center reconstruction. Gait analysis was performed, and the groups were compared according to the gait characteristics.ResultsThe mean temporospatial values were similar between the groups. The extension of the operated side was significantly lower in group 2 (?9.11 ± 8.92) than in group 1 (?1.87 ± 11.51) (P = .04). The mean longitudinal hip joint force was found to be significantly higher in group 2 (8.92 N/kg ± 0.54) than in group 1 (8.16 N/kg ± 0.66) (P = .04). The high hip center technique has been shown to increase the load on the hip and restrict the dynamic range of motion.ConclusionThe high hip center technique can decrease the survival of the implant and increase the fall risk as it increases the load on the hip and reduces the dynamic range of motion. The hip center should be reconstructed anatomically when possible in DDH patients who undergo unilateral THA.     

Treatment Outcomes of Long-Pulsed Nd: YAG Laser for Two Different Subtypes of Rosacea

Background: A variety of lasers have been used for the treatment of rosacea. However, treatment of this condition with long-pulsed neodymium-doped yttrium aluminium garnet laser has not been reported yet. Objective: To assess the efficacy and safety of long-pulsed neodymium-doped yttrium aluminium garnet laser in two different subtypes (erythematotelangiectatic and papulopustular) of rosacea. Methods: A total of 66 patients were enrolled in the study. All of the patients were treated with long-pulsed neodymium-doped yttrium aluminium garnet laser with 3- to 4-week intervals. Rosacea severity score was assessed by using photographs. Improvement in severity was defined as the percentage reduction in severity scores from baseline to the end of treatment. Patients were also asked about their own opinions of improvement at the end of the treatment. Side effects were also documented. Results: Good to excellent improvement was achieved in up to 50 percent of the patients in the erythematotelangiectatic and papulopustular groups. Percent improvement of global severity was significantly greater in the erythematotelangiectatic patients than in the papulopustular patients. The majority of patients from both groups noted a significant improvement of the lesions. Hypopigmented atrophic scars were seen in two patients. Conclusion: The long-pulsed neodymium-doped yttrium aluminium garnet laser is a safe and effective treatment for vascular and inflammatory lesions of rosacea.Rosacea is a chronic inflammatory cutaneous disorder with periods of exacerbations and remissions. Clinical findings are characterized by flushing, erythema, telangiectasia, papules, and pustules. There are four recognized subtypes—erythematotelangiectatic (ETR), papulopustular (PPR), phymatous, and ocular.1 Although angiogenic and sebaceous factors have been implicated in the etiopathology of the disease, it remains unclear. Vascular abnormalities, dermal matrix degeneration, environmental factors, and microorganisms may have a potential role in the development of rosacea.2Rosacea may significantly affect patients’ lives, leading to considerable psychological and social distress over appearance. Therefore, management of this condition is very important. There is no definite cure. Electrosurgery and lasers can be used to decrease vascular lesions.3 Topical and/or oral antibiotics can be used to suppress the inflammatory lesions. Although these methods are moderately successful in controlling symptoms, relapse usually occurs shortly after the cessation of therapy.4,5Many types of lasers and light devices have been increasingly used in the treatment of rosacea. However, the role of long-pulsed neodymium-doped yttrium aluminium garnet (Nd:YAG) laser in this condition has not been well-studied. In this study, the authors assessed the efficacy of long-pulsed Nd:YAG laser in treating patients with two different subtypes (ETR and PPR patients) of rosacea.     

The actual incidence of papaverine-induced priapism in patients with erectile dysfunction following penile colour Doppler ultrasonography

Penile color Doppler sonography is a valuable method for evaluating erectile dysfunction. However, there are some concerns about the safety of this method due to the intracorporeal pharmacological injection, which may cause priapism as a complication, resulting in penile fibrosis. To evaluate the actual incidence of papaverine-induced priapism in patients with erectile dysfunction (ED) who underwent penile colour Doppler sonography and to determine the safety of this diagnostic tool, a retrospective study was conducted using the database of our institution. A total of 672 men with ED underwent penile color Doppler ultrasonography with the intracorporeal injection of 60 mg papaverine hydrochloride. The patient characteristics of priapism cases were retrospectively evaluated. Priapism in 18 of the 672 patients (2.68%) was successfully treated with blood aspiration, irrigation and injection of an α-agonist medication, when needed. Patients with priapism were younger compared with those without priapism; mean age 45 ± 12.51 (20–68) versus 50.93 ± 12.04 (17–78) ( P  < 0.001). Penile Doppler ultrasound is a safe procedure in evaluating erectile dysfunction. The incidence of priapism, which is the most important complication of this procedure, is low and can be managed successfully with conservative approaches.     

Sexual function may be impaired during pregnancy in adolescent women

Prevalence of sexual dysfunctions is reported as high as 70% during pregnancy. However, there are limited data about the burden of sexual dysfunction in pregnant adolescents. This cross-sectional study was conducted in the outpatient antenatal clinic of our institution between October and December 2014. The total female sexual function index scores and domain scores were compared between adolescent and adult pregnant women. A total of 121 pregnant women participated in the study. Of those women, 29 (24.0%) were 21 years old or younger (Group 1), whereas the remaining were older (Group 2). The sexual dysfunction ratios were 41.4% and 23.9% in Groups 1 and 2, respectively (p = 0.068). The desire (3.29 vs. 2.79, p = 0.024) and arousal (3.48 vs. 2.71, p = 0.008) domain scores of adolescent pregnant women were significantly higher whereas the remaining domain scores (i.e. lubrication, orgasm, satisfaction and pain) were not significantly different. The adolescent women seem to be more prone to sexual dysfunctions during the course of pregnancy, especially in the third trimester. The health care providers should consider discussing the sexual life during pregnancy as a part of routine antenatal visit to improve sexual function and quality of life, especially among adolescent pregnant population.
