  • The Goldilocks technique for breast reconstruction utilizes redundant mastectomy flap tissue to construct a breast mound. This technique is suitable for women who decline, or are poor candidates for, traditional postmastectomy reconstruction. Moreover, this technique can be applied in secondary operations after the failure of initial reconstruction efforts. A 74-year-old patient underwent the Goldilocks procedure after reconstruction failure with an implant and acellular dermal matrix. At her 6-month follow-up, the cosmetic outcome of the procedure was satisfactory, and no complications were noted. Therefore, the Goldilocks procedure is a safe alternative to reconstruct breast mounds following reconstruction failure, especially in obese patients.

  • Centella asiatica is an herbal plant used on different continents by diverse ancient cultures and tribal groups. Historically. the extract has been used as a wound healing agent, The extract has three different triterpenoid ingredients: asiaticoside. asiatic acid, and madecassic acid. It has been reported that its wound healing activity is associated with the modulation of collagen synthesis in the skin dermis. The wound healing property of the extract has led to its commercial introduction under the trade name, Madecrlssol. As part of our program toward the development of new wound healing agents. structere activity relationship (SAR) studies have been performed by modifying asiatic acid. In this communication. the SAR study of esiatic acid for the development of an efficient woind healing agent is reported.

  • The authors performed rigid reconstruction using the sandwich technique for full-thickness chest wall defects by using two layers of acellular dermal matrix and bone cement. We assessed six patients who underwent chest wall reconstruction. Reconstruction was performed by sandwiching bone cement between two layers of acellular dermal matrix. In all patients, there was no defect of the overlying soft tissue, and primary closure was performed for external wounds. The average follow-up period was 4 years (range, 2-8 years). No major complications were noted. The sandwich technique can serve as an efficient and safe option for chest wall reconstruction.

  • The anterolateral thigh (ALT) flap has been extensively discussed in the literature as it allows for a wide variety and depth of tissues for complex wound coverage. Thanks to many cadaveric and angiographic studies of the subdermal plexus, it is to date ascertained that tailoring ALT thickness can be safely performed without compromising flap outcomes or causing additional morbidity. Recently, the authors applied and described a simpler, safer, and less time-consuming superthin ALT perforator (ALTP) free flap harvesting technique. The aim of this article is to show the versatility of the adipofascial flap harvested around the chosen perforators, which allowed us to safely expand the usage of ALTP superthin flaps.

  • In recent decades, tissue engineering advances have led to more skin substitutes becoming available. Acellular dermal matrix, initially developed for use in the treatment of full-thickness burns, is made by removing the cellular components from the dermis collected from donated bodies or animals. This class of scaffold is used to replace skin and soft tissue deficiencies in a variety of fields, including breast reconstruction, abdominal wall reconstruction, and burn treatment. Herein, we provide a detailed review of the clinical applications of acellular dermal matrix.

  • Postinflammatory hyperpigmentation (PIH) is a reactive hypermelanosis of the skin that occurs as a result of variable inflammatory processes, such as trauma, and many inflammatory conditions. Although a range of modalities of managing PIH have been reported, the treatment of PIH is challenging. In this report, a patient with PIH was treated using picosecond-domain Nd:YAG lasers. After three sessions of 1,064-nm picosecond-domain Nd:YAG laser treatment, the patient showed almost complete improvement with no remarkable side effects or recurrence over the duration of six months. Overall, 1,064-nm picosecond-domain Nd:YAG laser can be used effectively and safely for treating pigmented lesions in the dermis, particularly PIH, in Asian patients.

  • Clear cell hidradenoma is a tumor that originates from a sweat gland and typically involves the dermis and subcutaneous tissue. Malignant clear cell hidradenoma is very rare, and surgical excision is usually performed without imaging. There are few reports of the ultrasonographic findings of malignant clear cell hidradenomas. Herein, we present the ultrasonographic characteristics of a malignant clear cell hidradenoma.

  • The aim of this study is to evaluate contra-lateral breast (CLB) surface dose in Field-in-Field (FIF) technique for breast conserving surgery patients. For evaluation of surface dose in FIF technique, we have compared with other techniques, which were open fields (Open), metal wedge (MW), and enhanced dynamic wedge (EDW) techniques under same geometrical condition and prescribed dose. The three dimensional treatment planning system was used for dose optimization. For the verification of dose calculation, measurements using MOSFET detectors with Anderson Rando phantom were performed. The measured points for four different techniques were at the depth of 0cm (epidermis) and 0.5cm bolus (dermis), and spacing toward 2cm, 4cm, 6cm, 8cm, 10cm apart from the edge of tangential medial beam. The dose calculations were done in 0.25cm grid resolution by modified Batho method for inhomogeneity correction. In the planning results, the surface doses were differentiated in the range of $19.6{\sim}36.9%$, $33.2{\sim}138.2%$ for MW, $1.0{\sim}7.9%$, $1.6{\sim}37.4%$ for EDW, and for FIF at the depth of epidermis and dermis as compared to Open respectively. In the measurements, the surface doses were differentiated in the range of $11.1{\sim}71%$, $22.9{\sim}161%$ for MW, $4.1{\sim}15.5%$, $8.2{\sim}37.9%$ for EDW, and 4.9% for FIF at the depth of epidermis and dermis as compared to Open respectively. The surface doses were considered as underestimating in the planning calculation as compared to the measurement with MOSFET detectors. Was concluded as the lowest one among the techniques, even if it was compared with Open method. Our conclusion could be stated that the FIF technique could make the optimum dose distribution in Breast target, while effectively reduce the probability of secondary carcinogenesis due to undesirable scattered radiation to contra-lateral breast.

  • Since the summer of the year 1972 ulcer disease of common carp, colour carp ana goldfish had suddenly spread widely and caused a serious mortality at fish farms especially around Gim-hae and Yang-san, near Busan. The present study aimed to find out the causative organisms, histopathological changes and the way of treatment, and the results are summarized as follows : Two kinds of pathogenic bacteria, i. e, Chondrococcus columnaris and Aeromonas sp. were isolated from the mucus of the lesion. According to the macroscopic findings, these symptoms began with the hemorrhagic spots under scales which fell out, after the collapse of the dermis, which was followed by lesion to form ulcer, and then the muscle was exposed. The fin was eroded mostly from the distal part, but sometimes from the basal part. Gills showed grey colour, and this part of the tissue collapsed. According to the histopathological findings, the dermis was exposed after the collapsed of the epithelium of the skin, and the necrosis of the musculature occurred, the muscular fibre being destroyed. The epithelial cells of gill tissue proliferated, thus gill filaments were conglutinated and collapsed. Fatty degeneration happened at the liver but the other organs seem to be normal. Treatment with the following mixtures were effective the water temperature of $22\~25^{\circ}C$, but not effective when the temperature was under as low as $13\~15^{\circ}C$. Mixture 1. Aivet (HB-115.HCI) 0.3ppm Malachite green 0.2ppm. Dipterex 0.4ppm Mixture 2. Furanace (P-7138) 0.05ppm Malachite green 0.2ppm Dipterex 0.4ppm When lesion healed, the epithelium, dermis, and the muscular fibre were regenerated.

  • Objectives : The purpose of this study is to examine the effects of external application of HC001 on atopic dermatitis. HC001, newly composed herbal medicine combinations contains 9 medicinal herbs which are known to have anti-inflammatory and anti-allergic effects. We investigated the anti-inflammatory effects of HC001 on atopic dermatitis-like skin lesions in mice. Methods : Seven-week-old BALB/c mice were sensitized with DNCB to develop atopic dermatitis. Animals were divide into three group: Normal, DNCB (Negative control group), HC001 (Experimental group, treated with DNCB and HC001). Skin sections were stained with H&E to measure the thicknesses of the epidermis and dermis, respectively. The expression of NF-${\kappa}B$ protein was measured by western blotting analysis in skin lesion. Results : Topical HC001 treatment significantly restored the skin thickening and hyperplasia of the epidermis and dermis compared with DNCB-sensitized group in histopathological analyse. In addition, HC001 inhibited the expression of NF-${\kappa}B$ protein increased in DNCB-induced atopic dermatitis-like skin lesions in mice. Conclusions : These results suggest that HC001 may be useful as an external application agent for atopic dermatitis based on reductions of various inflammatory responses.
