Minimally invasive technique for tendo-achillis lengthening (Dr Kothari's modification of White's technique)
Kothari SY,Gupta A
Indian Journal of Physical Medicine and Rehabilitation , 2011,
Abstract: Tendo-achillis is a strong plantar flexor of the foot, therefore important for walking and running purposes. Correction of equinus contracture by tendo-achillis lengthening is essential for the proper biomechanics of the entire lower limb, both in standing and walking. Various techniques are available for TA lengthening. Z-plasty may be done in sagittal plane or coronal plane according to biomechanical or functional needs. In White's technique the tendon slides on itself and gets adjusted according to the level of spasticity. We modified the procedure by giving two smaller incisions so as to minimize skin complications.

International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.41005
Abstract:

Morton’s Neuroma is a common metatarsalgia in athletes created due to the entrapment of the inter-digital nerve inside the transverse inter-metatarsal ligament. The purpose of the present study is to draw the necessary conclusions from the use of a particular surgical treatment to release the digital nerve, accompanied by neurolysis in adults who exercise. On the whole, twenty five patients with twenty-five suffering extremities were treated. Five of them simultaneously had a Hallux Valgus type deformity and that supports the belief of the mechanical induce of this condition. Both ultrasonography and Magnetic Resonance Imaging (MRI) were used for the clinical evaluation of this condition. The pain was estimated via the Visual Analogue Scale (VAS). The patients were re-examined after three (1st postoperative), twelve (2nd postoperative) and twenty-four (3rd postoperative) months. A significant improvement (p < 0.0001) was noticed from the correlation between the pain before the surgery and the pain after the surgery via the Visual Analogue Scale (VAS). Most patients (15/25) did not display any discomfort or sensory disorder after surgery. The correct clinical evaluation as well as the correct and effective surgical intervention with the simultaneous repair of all the mechanical deformities of the foot provided better post-surgery progress in patients and increased the percentage of their rehabilitation of their previous activities.

Journal of Biological Sciences , 2003,
Abstract: The present study was undertaken with a view to develop a reproducible protocol for in vitro propagation of white mulberry (Morus alba L.). For this purpose, surface sterilization of the explants from field grown mature plants was done with 0.1% HgCl2 with a treatment duration of 5 minutes for shoot tip and that with 6 minutes for nodal segments. Between the two explants used, nodal explant exhibit comparatively better response to axillary shoot proliferation. Analysis of the results obtained from the proliferation experiment proved that effectiveness of cytokinin BA was better than that of Kn with respect to axillary shoot formation. And that MS medium supplemented with 1.0 mg l G 1 BA was found to be best where 100% of the explants proliferated with the axillary shoots having average length of 5.46 " 0.02 cm and a multiplication rate of 7 fold per 4-week. On the other hand, percentage of root induction and number of roots per shoot were largely affected by the concentration of MS medium and type of the auxins used. The highest percentage (100%) of root regeneration was obtained in half MS medium supplemented with 0.5% mg l G 1 IBA.
Solution of Nonlinear Stochastic Langevin’s Equation Using WHEP, Pickard and HPM Methods  [PDF]
Maha Hamed, Magdy A. El-Twail, Beih El-desouky, Mohamed A. El-Beltagy
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.53041
Abstract:

This paper introduces analytical and numerical solutions of the nonlinear Langevin’s equation under square nonlinearity with stochastic non-homogeneity. The solution is obtained by using the Wiener-Hermite expansion with perturbation (WHEP) technique, and the results are compared with those of Picard iterations and the homotopy perturbation method (HPM). The WHEP technique is used to obtain up to fourth order approximation for different number of corrections. The mean and variance of the solution are obtained and compared among the different methods, and some parametric studies are done by using Matlab.

Teaching Ultrasound Imaging for Central Line Placement—A Resident’s Perspective  [PDF]
Jayanta Mukherji,Nil Ural,Taqdees Sheikh,W. Scott Jellish
Open Journal of Anesthesiology (OJAnes) , 2013, DOI: 10.4236/ojanes.2013.35058
Abstract: The availability of ultrasound (US) devices has refined techniques for vascular access. The resident trainee’s ability to learn US techniques depends upon device availability, skills, and motivation of instructors. We hypothesized that hands-on teaching program of US techniques for vascular access would have a positive impact on the trainee’s perceptions. After IRB approval, PGY3 anesthesiology residents with limited prior experience in US-guided vascular access underwent close supervision by attending staff as they performed US-guided Internal Jugular Vein (IJV) central line placements. A total of 66 land mark (LM) and 75 US-guided IJV cannulation performed by 19 residents were supervised. Residents completing the study were more proactive with 68.4% agreeing to use US based techniques for an anticipated difficulty in accessing central lines. The graduating residents involved in the study all strongly agreed that US imaging for vascular access was within the scope of practice of all anesthesiologists, and that training guidelines be established and incorporated in their practice. Fifty eight percent of residents stated that their confidence and skill levels had significantly improved. Teaching US-guided techniques resulted in an increase employment of such techniques by graduating residents with no impediment attributed to knowledge deficits or inexperience. Residents were more proactive with using US for anticipated difficulty in IJV placement. A short neck, poor landmark, anticoagulation, morbid obesity favored US use by residents. Systematic teaching of US techniques is justified as it significantly improves the resident’s perceptions and confidence.

Modern Plastic Surgery (MPS) , 2015, DOI: 10.4236/mps.2015.53007
Abstract: This is a retrospective study on gigantomastia correction in obesity facing the technique of nipple-areolar grafts and its complexity. The main question is the technical-surgical care during its execution aiming to achieve reparative results that can return to these women the desire to live with better quality of life and health. Method: We performed a retrospective study of all obese patients with severe gigantomastia who underwent reduction mammaplasty with an operative technique using the superior pedicle, with special care for the nipple-papillary grafts. The study was carried out at a single institution between 2001 and 2013, in a total of 30 cases. This operative technique was presented at first time in 1980, with no changes up to now. We emphasized the perfect decortication of the areola and nipples until they were translucent after the maneuvers of Schwartzman and subsequent grafts operated in both breasts. Results: Results were considered satisfactory, from the reparative and aesthetic point of view, emphasizing the degree of improvement observed in women undergoing technique. Discussion: We can say that during all this time of aesthetic and therapeutic-restorative surgery, due to its realization in a single surgical time, there was big impact on the aesthetics of patients and on their families, even taking into account possible complications in the post-operative. Conclusion: The superior pedicle technique, performed as described here, is a safe and reliable procedure in patients with severe gigantomastia.
