    Perianal mucinous adenocarcinoma (PMA) is an oncologic rarity that poses a diagnostic and therapeutic dilemma for treating clinicians because there are few reported cases and an absence of definitive guidelines. We report a patient who had been treated with local surgery for recurrent perianal abscess with fistula for 3 years. Biopsy of the indurated tissue overlying his surgical scars revealed PMA. Neoadjuvant concurrent chemoradiotherapy followed by abdominoperineal resection was planned to address the locally advanced disease and ongoing sepsis. Our case is unique in that the fistula preceded carcinoma by only 3 years instead of the typical 10 years.

    Schwannomas are solitary, benign tumors arising from the nerve sheaths. They are frequently reported in the thorax predominantly in the posterior mediastinum, but are rarely seen to arise from the brachial plexus. Schwannomas are well demarcated lesions with a slow insidious growth. Presented is a case of a large brachial plexus schwannoma, masking as a cystic lesion in the lateral neck. The patient presented with concerns of a cystic mass progressively increasing in size over a period of four years, initially symptomless, but later caused numbness and tingling sensation over his right forearm, tip of right thumb and index finger. Following histological confirmation via fine needle aspiration and magnetic resonance imaging, the patient underwent surgical excision where by the tumor was dissected from its attachment to the nerve sheath. The patient recovered well, and by the third day post operatively, his neurological symptoms resolved completely. Upon follow up in clinic 1-week post-surgery, the scar had healed well, and his numbness or tingling sensation remained in abeyance. This case illustrates that a schwannoma may present insidiously as a cystic lesion and its possible origin may arise from the brachial plexus.

    The effects of topical application of Orthosiphon stamineus leaf extract on the rate of wound healing and histology of the healed wound were assessed. Four groups of adult male Sprague Dawley rats were experimentally wounded in the posterior neck area. A thin layer of blank placebo was applied topically to wounds of Group 1 rats. Wounds of experimental animals (Group 2 and 3) were dressed with placebo containing 5% and 10% O. stamineus extract, respectively. A thin layer of Intrasite gel® was applied topically to wounds of Group 4 animals as reference. Macroscopically, wounds dressed with placebo containing 5% (healed on day 14.50 ± 0.43) and 10% (healed on day 13.83 ± 0.21) O. stamineus extract each or Intrasite gel® (healed on day 13.13 ± 0.42) significantly accelerated the rate of wound healing compared to wounds dressed with blank placebo. Histological analysis of healed wounds confirmed the results. Wounds dressed with placebo containing 5%, 10% O.stamineus or Intrasite gel® showed markedly less scar width at wound enclosure and granulating tissue contained markedly more collagen, proliferating fibroblast with angiogenesis, and no inflammatory cells compared to wounds dressed with blank placebo. In conclusion, placebo containing 5% or 10% O. stamineus on extract-dressed wounds significantly accelerated the rate of wound healing in rats.

    Utilization of lasers and energy-based devices for surgical scar minimization has been substantially evaluated in placebo-controlled trials. The aim of this study was to compare reported measures of efficacy of lasers and energy-based devices in clinical trials in preventing surgical scar formation in a systematic review and network meta-analyses. Five electronic databases, PubMed, Scopus, Embase, ClinicalTrials.gov, and the Cochrane Library, were searched to retrieve relevant articles. The search was limited to randomized controlled trials that reported on clinical outcomes of surgical scars with treatment initiation no later than 6 months after surgery and a follow-up period of at least 3 months. A total of 18 randomized controlled trials involving 482 participants and 671 postsurgical wounds were included in the network meta-analyses. The results showed that the most efficacious treatments were achieved using low-level laser therapy) (weighted mean difference -3.78; 95% confidence interval (95% CI) -6.32, -1.24) and pulsed dye laser (weighted mean difference -2.46; 95% CI -4.53, -0.38). Nevertheless, low-level laser therapy and pulsed dye laser demonstrated comparable outcomes in surgical scar minimization (weighted mean difference -1.32, 95% CI -3.53, 0.89). The findings of this network meta-analyses suggest that low-level laser therapy and pulsed dye laser are both effective treatments for minimization of scar formation following primary closure of surgical wounds with comparable treatment outcomes.

    Eleven corneal specimens from nine patients with Salzmann's nodular degeneration of the cornea, together with all available clinical information, were collected for this study. The specimens were examined by light and electron microscopy. An antecedent keratitis was diagnosed by history and microscopic findings in every case. The corneal epithelium showed degenerative changes, its thickness varied, and in nodular areas it often consisted of only a single layer of flattened epithelial cells by light microscopy. Bowman's membrane was missing over the nodules, and in this zone there was excessive secretion of a basement membrane-like material. Hyaline degeneration of collagen, cellular debris, and electron-dense hyaline deposits were seen in the collagen of the nodules. The number of fibrocytes in the nodules varied from many that were active to a few that were degenerating. External irritation because of poor epithelial protection was interpreted as a causative factor, although other tissue repair mechanisms may also have played a role.

    The current standard of managing facial bone fractures is the use of rigid internal fixation. This method provides good stabilization and repair for mid-face fractures such as the zygomatico-orbitalfracture. Nowadays, for the young and old, patients want not only rapid bone healing, but also good facial aesthetics after surgical treatment following maxillofacial trauma. Therefore, osteosynthesis of fractures and inconspicuous post-operative scars are considered essential. The lower eyelid approach or modified blepharoplasty provides rapid access to the infraorbital rim as well as the orbital floor, while the lateral eyebrow incision gives direct access for fixation at the fronto-zygomatic suture. Combining the Gillies' approach and a single form of rigid internal fixation, good cosmetic results and function can be achieved. Cases using the micro-plate-system for thin infraorbital bones and the miniplate- system for thicker facial bones involving zygomatico-orbital fractures are described.

    This paper describes the use of stereophotogrammetry approach to measure and hence identify accurately threedimensional (3D) coordinates of important landmarks on a craniofacial surface. A "novel" technique dubbed as "natural features" technique was employed to accurately compute the 3D coordinates of selected craniofacial landmarks. The natural features technique involves the use of 3D coordinates of the natural features (such as acne, scar, corners of eyes, edge of mouth, point of chin, etc.) that appear on the craniofacial surface as an absolute stereophotogrammetric mapping control points. The 3D coordinates of the natural features were gained using digital photogrammetric bundle adjustment method. Validation of the proposed technique has firstly been carried out using mannequin and finally, it was applied on the real-life human faces. The result shows that the craniofacial landmark measurement accuracy of 0.8mm with one standard deviation can be successfully achieved by the proposed technique.

    In the field of tissue engineering and reconstruction, the development of efficient biomaterial is in high demand to achieve uncomplicated wound healing. Chronic wounds and excessive scarring are the major complications of tissue repair and, as this inadequate healing continues to increase, novel therapies and treatments for dysfunctional skin repair and reconstruction are important. This paper reviews the various aspects of the complications related to wound healing and focuses on chitosan because of its unique function in accelerating wound healing. The proliferation of keratinocytes is essential for wound closure, and adipose-derived stem cells play a significant role in wound healing. Thus, chitosan in combination with keratinocytes and adipose-derived stem cells may act as a vehicle for delivering cells, which would increase the proliferation of keratinocytes and help complete recovery from injuries.

    Eye socket contracture is a well-known late complication of enucleation surgery, and the additional insult of radiotherapy at an early age causes even further fibrosis and scarring of the socket. Management of the contracted socket is challenging, and several methods have been proposed. We report a case of eye socket contracture after enucleation and radiotherapy in which multiple reconstructive procedures failed. The recurrent contracture caused difficulty in housing and retaining the eye prosthesis. We reconstructed the lower eyelid with a facial artery myomucosal flap and nasolabial flap, and the upper eyelid with a Fricke flap following reconstruction of the orbital rims (supraorbital and infraorbital rims with a calvarial bone graft, and further augmentation of the infraorbital rim with a rib bone graft). Cosmesis post-reconstruction was acceptable and the prosthesis was retained very well.

    Acne vulgaris is a typical skin disorder among adolescence, causing inflammation of pilosebaceous follicle
    which characterized by comedones, papules, pustules, cysts, nodules and often scars in face, neck, upper trunk
    and arms. Propionibacterium acnes and Staphylococcus epidermidis have been recognized that play as a major
    role in acne formation. This study was conducted to compare the antimicrobial activity of five plant extracts
    namely Piper betle, Aloe vera, Solanum lycopersicum, Cinnamomum zeylanicum and Cucumis sativus against P.
    acnes and S. epidermidis. The well diffusion assay was used to determine the sensitivity of the samples, while
    the liquid dilution method was used for the determination of the minimal inhibition concentration (MIC). The
    result showed a remarkable antibacterial activity of Piper betle extract compared to other plant extracts and
    Doxycycline (positive control) against both of acne-inducing bacteria, P. acnes and S. epidermidis.

    Choanal stenosis is a well recognized late complication of radiotherapy for nasopharyngeal carcinoma. However velopharyngeal stenosis post radiotherapy for nasopharyngeal carcinoma is rare. We present here a case of bilateral choanal stenosis and velopharyngeal stenosis in a patient treated with radiotherapy for nasopharyngeal carcinoma. A 58-year-old woman presented to our otolaryngology clinic with a one year history of nasal obstruction. She was diagnosed to have nasopharyngeal carcinoma 12 years ago for which she received radiotherapy. Clinical examination revealed bilateral choanal stenosis and velopharyngeal stenosis. Treatment of choanal stenosis and velopharyngeal stenosis is challenging due to high incidence of recurrence and patients frequently require multiple procedures. The patient underwent a transnasal endoscopic excision of velopharyngeal scar tissue and widening of posterior choana using Surgitron®, mitomycin-C applied topically to the surgical wound and bilateral stenting under general anesthesia. The stents were kept for two weeks, and 3 years post operation velopharyngeal aperture and posterior choana remained patent. As illustrated in this case velopharyngeal stenosis can occur after radiotheraphy and should not be overlooked. Combine modality of transnasal endoscopic excision of velopharyngeal scar tissue, widening of choanal stenosis with Surgitron® followed by the application of mitomycin-C and stenting has been shown to be an effective option.

    BACKGROUND: As breast cancer incidence rises among younger women, there is a knowledge gap regarding the emotional, physical, and social effects of mastectomy, specifically in a crisis-affected country such as Syria. This study aimed to explore these effects on young women with breast cancer in Syria, taking into consideration the cultural significance of a woman's breast as part of her feminine identity.

    METHODS: A qualitative design, using semi-structured in-depth interviews with 10 young women with breast cancer who underwent mastectomy, was conducted between June to December 2022.

    RESULTS: Thematic analysis was used to analyze the data, and five main themes were identified: (1) psychological and emotional well-being (altered self-esteem and femininity, impact on sexual life and relationships, psychological distress associated with mastectomy, mirror trauma and the need for psychological care); (2) body image and breast reconstruction (the dilemma over reconstruction decision, body image and clothing and lack of access to prosthetic information/services); (3) social and interpersonal factors (lack of marriage choices and society's view and stigma); (4) coping mechanisms with mastectomy effects (family support; faith in god almighty; comparing their situation to others and use of prosthetics) and (5) physical health and functioning (physical effects on mobility and function).

    CONCLUSION: Mastectomy has significant physical, emotional, and social consequences on young women with breast cancer, particularly in crisis-affected Syria where access to breast reconstruction is limited. It is crucial for healthcare professionals to understand these impacts, to raise awareness, encourage early detection, and promote less aggressive treatments to improve women's quality of life.

    Chronic wounds and scar tissues are prone to skin cancer. In 1828, Jean-Nicholas Marjolin described the occurrence of tumours in post-traumatic scar tissue. He did not, however, identify the warty ulcers he described as malignant. It was Dupuytren, who about two years later, noted that these lesions were cancerous. The eponym was bestowed by Da Costa in 1903. Marjolin's ulcer no longer refers only to carcinomas secondary to burns and is classified as a malignancy that arises from previously traumatised, chronically inflamed, or scarred skin. It has been reported in relation to osteomyelitis, venous stasis ulcer, tropical ulcers, chronic decubitus ulcer, frostbite, pilonidal sinus, vaccination site, urinary fistula, hidradenitis suppurativa, skin graft donor site, gunshot wounds, puncture wounds, dog bites, and lupus rash. Early arising Marjolin's ulcer has rarely been described in literature. In this case report, we present the CT appearances of Marjolin's ulcer in the left gluteal region of a young man.

    This paper reports on a preliminary genetic investigation of two commercially cultured oyster species, white and black scar oysters, Crassostrea belcheri and C. iredalei, respectively. A total
    of 68 individuals from three different areas in Malaysia namely a C. belcheri sample from Semporna (Sabah) and two populations of C. iredalei from Trai (Sabah) and Setiu (Terengganu) were
    collected and analysed based on sequence analysis of cytochrome oxidase subunit I (COI). Alignment of COI gene was done using Alignment Explorer/CLUSTAL in Mega4.1. Genetic distances
    within and between populations were calculated using Kimura 2-parameter. Phylogenetic dendograms were generated by Neighbour-Joining (NJ) and Maximum Parsimony (MP) methods.
    The ingroup taxa were divided into two main clusters separating C. iredalei and C. belcheri with 99% bootstrap value. The two C. iredalei populations were homogeneous suggesting high
    connectivity in the South China Sea for this species. The common central haplotype in the minimum spanning networks programme is believed to be the ancestral variant for the two species. The
    findings from this study provides important baseline data for the aquaculture, management and monitoring of cultured populations of the oyster species.

    Facial burns are common and have a significant impact on patient function and psychosocial well being. Human amnion has been used for many years as a temporary biological wound dressing in the management of partial thickness burns. The observed advantages of human amnion treatment include pain relief, ease of use, prevention of infection and acceleration of wound healing.

    INTRODUCTION: Autologous skin grafting is the mainstay of treatment in burn patients. Extensive full thickness burns remains a challenge to the burns surgeon due to the lack of autologous skin donor sites. The conventional split thickness skin grafting (SSG) and the Meek micrografting (Meek) technique are part of the armamentarium of the burns surgeon to curtail the challenge of paucity of donor sites. With advances in burn care, mortality rates of burn patients have reduced. As a result, with more patients surviving acute burn, there is a paradigm shift of research towards assessment of functional outcomes and quality of life of the burn survivors. As there is lack of research regarding the functional outcome of the Meek technique, this study was designed to examine the long term functional outcome of the Meek technique and SSG in burns.

    METHOD: A cross-sectional study was conducted in Hospital Universiti Sains Malaysia to assess patients with burns between 10 to 40% total body surface area (TBSA) and with at least one year after injury. The Burn Specific Health Score-brief (BSHS-B) was utilized to compare the functional outcome whilst the Vancouver Scar Scale (VSS) was used for comparison on the scar outcome of the two skin grafting techniques.

    RESULTS: Forty three patients (Meek,15; SSG,28) were included. The mean current age (years old) of Meek and SSG was 24.7 (range, 7-75) and 25.9 (range, 7-65) respectively. The mean TBSA (%) of the Meek group was 26.7 (range, 13-40) while that of the SSG group was 16.1 (range, 10-32). A simplified domain structure was used for the BSHS-B questionnaire. The work and sexuality subscale were analyzed separately due to missing data. There mean scores of affect and relations was higher in Meek compared to SSG (Meek, 3.86; SSG, 3.75; p > 0.05). Function domain was also better in Meek compared to SSG (Meek, 3.88; SSG, 3.73; p > 0.05). The Meek group displayed superior scar outcome compared to SSG as evidenced by the statistically significant difference in score for the pigmentation, pliability, height and total VSS score.

    CONCLUSION: The Meek group showed more favorable BSHS-B scores compared to the SSG group. The scar outcome of the Meek technique is significantly superior to SSG. Therefore, the Meek technique is superior in the management of burns because the long term scar and functional outcome of this technique is better compared to conventional SSG.

    Cold snare polypectomy (CSP) should be performed for benign lesions, though an accurate diagnosis is sometimes difficult with only white light observation. Irregular findings by narrow-band imaging (NBI) are useful for differentiating malignant lesions from benign lesions, and cases with this finding are not expected for CSP. We present a diminutive T1 cancer resected by CSP as a reflection case. A 68-year-old man underwent colonoscopy for surveillance after polypectomy. A reddish polyp 4 mm in size was detected at the rectum. White light observation showed no depression, but a slight, heterogeneous color change. NBI magnification showed irregular vessel and surface patterns. The polyp was diagnosed as intramucosal cancer. Even though cancerous lesions are regularly resected by endoscopic mucosal resection (EMR), this polyp was resected by CSP in daycare surgery because the patient requested not to be treated by EMR but by CSP, which needed an admission to our institution. The surgeon thought the polyp could be completely resected by CSP. It was thoroughly resected, and a histological examination showed submucosal cancer with a positive vertical margin. Additional surgical resection was not accepted by the patient, since he had received total gastrectomy for gastric cancer and a right hemicolectomy for colonic cancer in the past 7 years. He underwent follow-up colonoscopy 2 months after the CSP. Although there were no recurrent endoscopic findings, endoscopic submucosal dissection was performed to the scar area. The histological examination showed no residual tumor. In conclusion, CSP should only be adopted for benign cases, as cancerous lesions have a possibility for invading the submucosa, like in our case.

    A 23-year-old Malay man presented with headache for one-month duration. It was associated with painless blurring of vision of the right eye. He had loss of appetite and reduced weight but no night sweats or hemoptysis. His visual acuity on the right eye was 6/45 and improved to 6/15 with pinhole. Right fundus examination revealed a choroidal tuberculoma located at one disc diameter away from optic disc superiorly with mild vitritis. Systemic examinations revealed no significant finding. Mantoux test reading was 22 mm with erythrocyte sedimentation rate that was 14 mm/h. Other blood investigations were negative with normal chest radiography. The computerized tomography scan of the brain revealed multiple cerebral abscesses. A clinical diagnosis of right ocular tuberculosis with multiple cerebral abscesses was made. He was treated with antituberculosis chemotherapy for one year which divided into intensive phase for three months and maintenance phase for nine months. Cerebral abscesses resolved after three months of antituberculosis drugs and at one-year follow-up, and the choroidal tuberculoma resolved completely with scar formation and significant macular striae.
