Abstract Autologous fat grafting for buttock augmentation is one of the fastest growing plastic surgery procedures, but has also received significant publicity for the relatively high mortality rate secondary to fat emboli. The literature has grown exponentially in the past 5 years on this subject, helping to clarify our knowledge and providing recommendations to minimize risks, including avoiding intramuscular injections, placing the patient in the jackknife position, and utilizing larger-bore cannulas. Since the application of these recommendations, the rate of pulmonary fat embolism has decreased from 0.097% to 0.04%, with a current mortality of 1 in 14,921, making it statistically safer than abdominoplasty. Despite the evolution in our knowledge, techniques, and outcomes, it remains of utmost importance to properly select and educate patients about the safety of fat grafting for buttock augmentation.

Topical Negative Pressure

Introduction : The topical negative pressure therapy (TNP) is a non-invasive method to treat chronic and acute wounds locally, using a continuous or intermittent negative pressure. The objective of this study is to present the first experience of this type of treatment used in clinical cases in our department. By presenting these cases, we highlight indication and efficiency of this new technique applied in relatively complicated situations, at the same time it also allows a significant improvement in treating injuries and chronic wounds. Materials and methods : In this study, we present the recent experience of the Department of Reconstructive and Plastic Surgery of the University Hospital Center of Avicenne in Rabat. This therapy was used for the first time this year (in 2014), in three young patients who presented with chronic wounds associated with local and general factors that are unfavorable for the healing process. Results : In all three of our cases we obtained highly satisfactory clinical results. TNP allows wounds to bud in a shorter time, as well as a fast healing by second intention due to controlled wound healing or split-skin graft without using flaps. This enables to decrease the margin of error, the time and the number of dressing replacements, and to reduce the length of hospital stay. Conclusion : This is an expensive and specific equipment. However, the cost-benefit ratio analysis shows that it is an essential method that should be part of our therapeutic strategies.

Introduction: In most of the patients with chronic granulating wounds split skin grafting is the preferred option for coverage of the wounds. Split skin grafts may be applied directly on the granulation tissue or it may be applied after complete removal of granulation tissue. Opinions are divided on this issue. Objectives: To compare the skin take between the split thickness skin grafting on chronic wounds after removal and without removal of granulation tissue in the same patient. Methods: This is a longitudinal type of follow up and comparative study and was carried out in the Department of Plastic Surgery of Dhaka Medical College Hospital, Dhaka between the periods of January 2008 up to December 2009. The study population included the patients with chronic wounds attending the Department of Plastic Surgery of Dhaka Medical College Hospital and in the Plastic Surgery Department of Combined Military Hospital, Dhaka. In this study a total of 57 patients with clinically non infected chronic granulating wounds requiring skin graft were selected. Among which 50 patients were from Dhaka Medical College Hospital and 7 patients were from Combined Military Hospital, Dhaka. In the same patient wounds were divided into Group A and B. In Group A granulation tissue were removed before skin grafting and in Group B the granulation tissues were not removed before skin grafting and skin graft was applied directly on the granulation tissue. 49 JAFMC Bangladesh. Vol 9, No 2 (December) 2013 Results: In the final skin take assessment it was found that in Group A, 49 (86.0%) patients had a take between 91-100% and 8 (14.0%) patients had a take between 81-90%. None of the patients in this group had a take <80%. In Group B, 30(52.6%) patients had a take between 91-100% and 18(31.6%) patients had a take between 81-90%. There were 9 (15.8%) patients who had a take of <80% and among them 02 patients had a take <70%. Statistically this was significant. Conclusion: Whenever the granulation tissue is removed, the recipient bed has a better chance of skin take as far as infection is concerned. But it must be ensured that haemostasis is achieved before application of the graft. DOI: http://dx.doi.org/10.3329/jafmc.v9i2.21826 Journal of Armed Forces Medical College Bangladesh Vol.9(2) 2013

Microscope Objective Lens

The optic axis of an electron microscope objective lens is usually assumed to be straight and co-linear with the mechanical center. No reason exists to assume such perfection and, indeed, simple reasoning suggests that it is a complicated curve. A current centered objective lens with a non-linear optic axis when used in conjunction with other lenses, leads to serious image errors if the nature of the specimen is such as to produce intense inelastic scattering.

Palladium single-crystal films have been prepared by Matthews in ultra-high vacuum by evaporation onto (001) NaCl substrates cleaved in-situ, and maintained at ∼ 350° C. Murr has also produced large-grained and single-crystal Pd films by high-rate evaporation onto (001) NaCl air-cleaved substrates at 350°C. In the present work, very large (∼ 3cm2), continuous single-crystal films of Pd have been prepared by flash evaporation onto air-cleaved (001) NaCl substrates at temperatures at or below 250°C. Evaporation rates estimated to be ≧ 2000 Å/sec, were obtained by effectively short-circuiting 1 mil tungsten evaporation boats in a self-regulating system which maintained an optimum load current of approximately 90 amperes; corresponding to a current density through the boat of ∼ 4 × 104 amperes/cm2.

For future high density magneto-optical recording materials, a Bi-substituted garnet film ((BiDy)3(FeGa)5O12) is an attractive candidate since it has strong magneto-optic effect at short wavelengths less than 600 nm. The signal in read back performance at 500 nm using a garnet film can be an order of magnitude higher than a current rare earth-transition metal amorphous film. However, the granularity and surface roughness of such crystalline garnet films are the key to control for minimizing media noise.We have demonstrated a new technique to fabricate a garnet film which has much smaller grain size and smoother surfaces than those annealed in a conventional oven. This method employs a high ramp-up rate annealing (Γ = 50 ~ 100 C/s) in nitrogen atmosphere. Fig.1 shows a typical microstruture of a Bi-susbtituted garnet film deposited by r.f. sputtering and then subsequently crystallized by a rapid thermal annealing technique at Γ = 50 C/s at 650 °C for 2 min. The structure is a single phase of garnet, and a grain size is about 300A.

Grafts of cultured allogenic or autogenic keratlnocytes have proven to be an effective treatment of chronic wounds and burns. This study utilized a collagen substrate for keratinocyte and fibroblast attachment. The substrate provided mechanical stability and augmented graft manipulation onto the wound bed. Graft integrity was confirmed by light and transmission electron microscopy.Bovine Type I dermal collagen sheets (100 μm thick) were crosslinked with 254 nm UV light (13.5 Joules/cm2) to improve mechanical properties and reduce degradation. A single cell suspension of third passage neonatal foreskin fibroblasts were plated onto the collagen. Five days later, a single cell suspension of first passage neonatal foreskin keratinocytes were plated on the opposite side of the collagen. The grafts were cultured for one month.The grafts were fixed in phosphate buffered 4% formaldehyde/1% glutaraldehyde for 24 hours. Graft pieces were then washed in 0.13 M phosphate buffer, post-fixed in 1% osmium tetroxide, dehydrated, and embedded in Polybed 812.

A current theme in the study of the critical current density behavior of YBa2Cu3O7-δ (YBCO) grain boundaries is that their electromagnetic properties are heterogeneous on various length scales ranging from 10s of microns to ˜ 1 Å. Recently, combined electromagnetic and TEM studies on four flux-grown bicrystals have demonstrated a direct correlation between the length scale of the boundaries’ saw-tooth facet configurations and the apparent length scale of the electrical heterogeneity. In that work, enhanced critical current densities are observed at applied fields where the facet period is commensurate with the spacing of the Abrikosov flux vortices which must be pinned if higher critical current density values are recorded. To understand the microstructural origin of the flux pinning, the grain boundary topography and grain boundary dislocation (GBD) network structure of [001] tilt YBCO bicrystals were studied by TEM and HRTEM.
