A custom-made implant was fabricated using rapid prototyping (RP) for the TMJ surgery. The stability of the metallic implant was validated using a finite element analysis. The results of finite elements were stable and the design of the TMJ implant was suitable as per the patient's need. The customised implant was made using a fused deposition modelling method of RP and a vertical machining centre. The implant has provided normal jaw function for over 2 years since surgery. The approach utilised will be helpful in providing successful treatment to the deformed mandible and the mandible joints. This method allows to customise and to accurately fabricatie the implant. Advantages of this approach are that the physical model of the implant was tested for stability before the implantation, the surgeon can plan and rehearse the surgery in advance, it is a less invasive and less time-consuming surgical procedure.

Inferiorly based abdominal flaps are reliable and versatile flaps that can cover large defects of the forearm and hand. Here we present a modified abdominal flap design based exclusively on the superficial inferior epigastric artery (SIEA) to reconstruct the hand and forearm's extensive defects. The donor site is closed primarily. Methods This is a retrospective study of the patients who underwent reconstruction of hand and forearm defects with SIEA flap from 2006 to 2018. The flap was designed on the ipsilateral hemiabdomen with a narrow pedicle based on the SIEA. We describe the anatomical basis and the outcomes of SIEA flap for reconstruction of the hand and forearm's extensive defects. Results Forty-eight soft tissue defects of the hand and forearm were reconstructed with the SIEA-based abdominal flap. Twenty-nine (60.41%) dorsal defects, 4 (8.33%) volar defects, 4 (8.33%) circumferential defects, 6 (12.5%) hand amputation stump, and 5 (10.41%) finger and thumb defects were covered using the SIEA flap. Forty-seven (97.91%) flaps had complete survival, whereas 1 (2.08%) flap had distal necrosis at the time of division. One (2.08%) flap had marginal necrosis, and 1 (2.08%) flap had distal necrosis after the division. The donor site was closed primarily in all patients. One (2.08%) patient had wound dehiscence at the abdominal donor site. All flaps gave excellent coverage with a satisfactory contour. Conclusion Abdominal flap based on SIEA is a safe, reliable, and versatile flap for the reconstruction of extensive soft-tissue defects of the hand and forearm. An ability to provide a large amount of skin and soft tissue and the abdominal donor site's primary closure make it a favorable option for upper limb reconstruction in regions with limited resources and technical expertise.

A total of 100 cases were studied from January 2003 to January 2004. The swab for culture was taken from various sites of burn wounds on the seventh day after admission. Culture was done and analyzed to individual member of microbial flora, and then the sensitivity to various antibiotics was studied. In our study we found that in our set-up Pseudomonas was the commonest microorganism isolated and Piperacillin and Amikacin were most effective antibiotics against them. Klebsiella and E.Coli responded best to Ciprofloxacin. Staphylococcus Aureus was sensitive to Amikacin and Erythromycin and no resistance was found against Vancomycin. Proteus responded to Ciprofloxacin. A combination of Ciprofloxacin and Amikacin can be considered as first line therapy for management of burn infections with selective use of Piperacillin in...

The recent literature does not validate its only prevalence in the extremities of the adult population. Statistics reveal that adult population has the highest prevalence rate; 30 % of reported cases occur in the children and adolescents. It is very rare in pregnancy. Carcinomas may be diagnosed concurrently with pregnancy in approximately 0.1 % of cases, but sarcomas are rare. We report a 21-year-old woman with synovial sarcoma on anterior abdominal wall at 34th week of gestation, which was clinically diagnosed as desmoid tumor. Tumor was totally excised. After 6 months, it relapsed in the form of multiple abdominal wall swellings and ascites.

Reports of the successful repair of vessels smaller than one mm in diameter are currently commonplace. However, the art of microvascular surgery has not yet been perfected, as evidenced by frequent reports of clinical failure. This study was undertaken to determine the effect of a ′temporary stent′ on the patency rates of vessels and to study the vascular endothelium under electron microscope to determine the changes caused by both conventional and the experimental technique. Materials and Methods: This study consisted of two distinct arms. In the first part (27 rats) we studied the effect of temporary stenting on end to end anastomosis vis a vis its patency rates. While in the second part (30 rats) the same experiment was performed with a view to examine the anastomosis under electron microscope at different time frames to study the state of...
