The purpose of this study is to evaluate macroscopic and microscopic appearance of a new implant design, with particular emphasis given to the type of prosthesis connection. Two dental implants of the same type (Torque Type(®), WinSix(®), BioSAFin. S.r.l. – Ancona, Italy), with sandblasted and acid etched surfaces (Micro Rough Surface(®)), but differing from each other for the prosthesis connection system, were examined by scanning electron microscope (SEM) analysis at different magnifications: TTI implant, with a hexagonal internal connection, and TTX implant, with a hexagonal external connection. SEM analysis showed that the Torque Type(®) implant is characterized by a truncated cone shape with tapered tips. The implant body showed a double loop thread and double pitch with blunt tips. For both types of connection, the implant neck was 0.7 mm in height with a 3% taper. This implant design may be able to guarantee osteotomic properties at the time of insertion in a surgical site suitably prepared, a facilitated screwing, thanks to the thread pitch and to the broad and deep draining grooves, thereby ensuring a good primary stability. The different connection design appears defined and precise, in order to ensure a good interface between the fixture and the prosthetic components. Therefore, this design appears to be particularly suitable in cases where a good primary stability is necessary and a precise coupling between endosseous and prosthetic components, as it allows an easy insertion of the fixture even in conditions of reduced bone availability, and in cases of immediately loaded full-arch rehabilitations.

Osteoporosis in haemophilic patient, rehabilitative aspects.

Clin Cases Miner Bone Metab. 2012 May; 9(2): 96-9

The continuous improvement of substitution and antiviral treatments available to date (at least in countries with greater economic and social development) allow better survival of patients with haemophilia, both as regards the duration and quality of life, to the point that the haemophilic arthropathy, that is the co-morbidity almost always present and extremely debilitating, come to be treated successfully using prosthetic joint replacement surgery. This has further highlighted other aspects of disease such as osteopenia or osteoporosis, which frequently occurs in these patients, and in recent years has aroused the interest of research.Rehabilitation plays a vital role in helping to tackle the different risk factors in young patients, in containing the consequences of the disease on the skeletal and muscle apparatus such as on the recovery after surgery and prosthetic.

To study the effect of Buflomedil on the morphological repair on crush injury of sciatic nerve and also the expression of vascular endothelial growth factor (VEGF).Rat sciatic nerves were crushed by pincers. All of the 400 Sprague Dawley rats were randomly divided into: Sham-operated; saline; saline + VEGF-antibody; Buflomedil; and Buflomedil + VEGF antibody groups. The expression of VEGF in dorsal root ganglia (DRGs), following crush injury to sciatic nerves, was studied by RT-PCR, immunohistochemistry. The effects of Buflomedil on expression of VEGF and repair of neural pathology were also evaluated.VEGF mRNA was significantly increased in Buflomedil and Buflomedil + VEGF-antibody groups, compared with other groups. The number of VEGF-positive neurons was significantly increased in the Buflomedil and the saline groups. Besides, Buflomedil also caused less pathological changes in DRGs.The vasoactive agent Buflomedil may decrease the pathological lesion and improve the functional rehabilitation of peripheral nerves, which may correlate to upregulation of the expression of VEGF, following crush injury to the peripheral nerves.

Echo-guided estimation of formula for paravertebral block in neonates, infants and children till 5 years.

The aim of the study was to derive a clinically useful formula for paravertebral block for thoracic, lumbar (L1) and cervical level (C6) as per the ultrasound-guided measurements in neonates, infants and children up to 5 years of age.Observational study.Seventy-five patients from 2 days to 60 months were included. Paravertebral transverse ultrasound scans at cervical (C6), thoracic (T1-12) and lumbar (L1) regions were viewed to determine the optimal insertion point and depth for performing paravertebral blocks. The lateral distance from the spinous process to the insertion point and the depth from the insertion point to the paravertebral space or reference point (point just anterior to the transverse process) were measured.Data was analyzed using the SPSS (V 10.0) package. Preliminary data was collected with the actual values of paravertebral parameters and weight and age. Initially, Pearson Bivariate Correlation Coefficients were calculated between parameters and age and weight so as to predict paravertebral parameters with the help of weight and age. As there were statistically significant associations between parameters and age and weight, an attempt was made to predict parameters with the help of age and weight. Multiple regression method (forward) was applied by taking parameters as dependent variables and age and weight as independent variables.Age and weight correlated very well (statistically significant) with paravertebral parameters; hence, prediction (regression) equations were calculated as: Prediction (regression) equation: C6A=0.005 × wt + 0.005 × age + 1.31 C6B=0.009 × wt + 0.002 × age + 1.78 T1-12 A=0.02 × wt + 0.003 × age + 0.93 T1 to 12 B=0.03 × wt + 0.03 × age + 1.02 L1A=0.03 × wt + 0.02 × age + 0.91 L1B=0.05 × wt + 0.02 × age + 0.94We could derive equations to predict the values for paravertebral blocks in centimetres at different levels in the study population.

Autologous Gastrointestinal Reconstruction: Review of the Optimal Nontransplant Surgical Options for Adults and Children With Short Bowel Syndrome.

Filed under: Rehab Centers

Nutr Clin Pract. 2012 Oct 18;
Rege AS, Sudan DL

Short bowel syndrome (SBS) results in loss of absorptive capacity of the development of gut, leading to malabsorption due to protein, energy, fluid, and electrolyte loss and imbalance while on enteral diet alone. Various nonsurgical and surgical therapeutic options that have emerged improve the survival outcome following SBS in both children and adults. An individualized, complex multidisciplinary approach to medical and surgical intestinal rehabilitation is needed to provide an opportunity for enteral autonomy to be possible in a patient with SBS. The remnant bowel plays a very pivotal role in autologous gastrointestinal reconstruction (AGIR) surgery. Intestinal transplantation, although promising and potentially life-saving for SBS, should be reserved for patients with failed AGIR or those who have no prospect for autologous enteral autonomy. This article reviews the evolution of nontransplant surgical management of patients with SBS.
