A new pattern for using both thoracic arteries to revascularize the entire heart: the pi-graft

We present a complex graft for total arterial revascularization based on bilateral skeletonized internal thoracic arteries (ITA). The lower two-thirds of the free right ITA is anastomosed to the proximal segment of the left in situ ITA using the T-graft technique (Tector-Barner-Calafiore). The free, transected distal part of the left ITA is then anastomosed end-to-side on free right ITA (T-on-T anastomosis). In addition, the technique may use another graft extending the proximal third of the in situ right ITA with the free radial artery for right-sided revascularization. The entire operation can be performed off-pump to avoid any procedure on the ascending aorta.     

Infant births during the internal night are at increased risk for operative delivery and NICU admission

Purpose  

The purpose of the present study was to compare neonatal morbidity between night and the rest of day and investigate potential differences of birth outcomes during the internal night.     

Taeniasis among Refugees Living on Thailand–Myanmar Border, 2012

We tested refugee camp residents on the Thailand–Myanmar border for Taenia solium infection. Taeniasis prevalence was consistent with that for other disease-endemic regions, but seropositivity indicating T. solium taeniasis was rare. Seropositivity indicating cysticercosis was 5.5% in humans, and 3.2% in pigs. Corralling pigs and providing latrines may control transmission of these tapeworms within this camp.     

Predictors of prolonged mechanical ventilation following aorta no-touch off-pump coronary artery bypass surgery.

OBJECTIVE: To identify parameters associated with prolonged mechanical ventilation (PMV) (>48 h) after off-pump coronary artery bypass (OPCAB) in our patient population. MATERIALS AND METHODS: From February 2001 to November 2005, we operated on 1359 patients for isolated coronary revascularization with the pi-circuit technique, consisting of: (1) beating heart, (2) OPCAB, (3) aorta no-touch, (4) use of composite grafts, and (5) arterial revascularization. RESULTS: From the total number of our patients, 1320 patients had been extubated within 48 h postoperatively (Group A) and 39 patients needed PMV (Group B). In our study we have found that PMV were associated with advanced age (64.74+/-9.85 Group A vs 68.43+/-10.03 Group B, p<0.02) as well as higher incidence with octogenarians (4.4% Group A vs 10.2% Group B, p=0.09). Patients with preoperative history of transient ischemic attacks (TIAs) or stroke were more likely to belong to Group B (1.5% Group A vs 7.7% Group B, p<0.02; 2.8% Group A vs 10.3% Group B, p<0.02, respectively). Preoperative intra-aortic balloon pump (IABP) insertion was associated with PMV (1.6% Group A vs 15.4% Group B, p<0.0005). Unexpectedly, neither COPD nor obesity was associated with PMV (4.9% Group A vs 7.7% Group B, p=NS, 21.7% Group A vs 23.1% Group B, p=NS, respectively). CONCLUSION: In this study, PMV following aorta no-touch OPCAB was related to preoperative variables: age, octogenarians, preoperative IABP, TIA, and stroke. There was no relation between PMV and any of the operative data.     

Cysticercosis in labial tissue. Case report

Cysticercosis is a condition in which a human acts as the intermediate host of Taenia solium , a pork tapeworm. The larvae infestation sites frequently include cerebral tissue, ocular organs, and muscles. The present case report describes a rare incidence of cysticercosis in the oral region.     

Fluorescence in situ hybridisation sperm examination is significantly impaired in all categories of male infertility

To study the outcome of FISH sperm examination in cases with sperm pathology and outline the potential correlation with certain chromosomal defects. A retrospective study of prospectively collected data was performed in IAKENTRO, Infertility Treatment Center. Rates of abnormal FISH semen examination were compared between male infertility patients and fertile controls. Detection of abnormal FISH semen examination as well as each chromosomal abnormality detected was correlated with each sperm deficiency (asthenozoospermia, oligozoospermia and teratozoospermia) in a univariate regression model. There were 72 male partners included, of which 52 male infertility patients and 20 controls. The rate of abnormal sperm FISH examination was significantly higher in patients’ group (55.8% vs. 15.0% for controls, p = .002). Asthenozoospermia, oligozoospermia and teratozoospermia were significantly correlated with detection of abnormal FISH examination (p = .004, p = .01 and p < .001 respectively). Teratospermia was significantly correlated with increased aneuploidy rate for chromosome 17 (p = .005), chromosome X (p = .05) and Y (p = .03). FISH examination reveals pathology in a significant proportion of patients with sperm defects and should be recommended to achieve early detection of chromosomal defects that may postpone favourable reproductive outcome.
