  3. An in-vitro method for buccal adhesion studies: importance of instrument variables
    Wong CF, Yuen KH, Peh KK
    Int J Pharm, 1999 Mar 25;180(1):47-57.
    PMID: 10089291
    A method using a texture analyzer equipment and chicken pouch as the biological tissue was investigated for measuring the bioadhesive properties of polymers under simulated buccal conditions. The method was evaluated using two polymers, namely Carbopol 974P and Methocel K4M while the instrument variables studied included the contact force, contact time and speed of withdrawal of the probe from the tissue. The parameters measured were the work of adhesion and peak detachment force. Longer contact time and faster probe speed not only gave better reproducibility of results, but also better sensitivities for both parameters measured. On the other hand, a certain level of contact force was found essential for achieving good bioadhesion, above which there was no further contribution to the bioadhesion process. When the method was applied to determine the bioadhesiveness of several polymers, the values obtained for the work of adhesion and peak detachment force were quite consistent in the ranking of the polymers. The Carbopols were found to have the highest values, followed by gelatin, sodium carboxymethyl celluloses and hydroxypropylmethyl celluloses. On the other hand, Alginic acid, Eudragit RLPO and RSPO, and Chitosan appeared to have low bioadhesive values.

  4. Fulltext Probiotics and Paraprobiotics in Viral Infection: Clinical Application and Effects on the Innate and Acquired Immune Systems
    Kanauchi O, Andoh A, AbuBakar S, Yamamoto N
    Curr Pharm Des, 2018;24(6):710-717.
    PMID: 29345577 DOI: 10.2174/1381612824666180116163411
    Recently, the risk of viral infection has dramatically increased owing to changes in human ecology such as global warming and an increased geographical movement of people and goods. However, the efficacy of vaccines and remedies for infectious diseases is limited by the high mutation rates of viruses, especially, RNA viruses. Here, we comprehensively review the effectiveness of several probiotics and paraprobiotics (sterilized probiotics) for the prevention or treatment of virally-induced infectious diseases. We discuss the unique roles of these agents in modulating the cross-talk between commensal bacteria and the mucosal immune system. In addition, we provide an overview of the unique mechanism by which viruses are eliminated through the stimulation of type 1 interferon production by probiotics and paraprobiotics via the activation of dendritic cells. Although further detailed research is necessary in the future, probiotics and/or paraprobiotics are expected to be among the rational adjunctive options for the treatment of various viral diseases.

    MyJurnal
    Pyogenic granuloma is a benign lesion which is commonly found in the oral cavity. It is a reactive inflammatory process of the injured mucosa to trauma. It can appear as a sessile or pedunculated mass with smooth or lobulated surface, which sometimes can mimic malignant lesion. Excision biopsy of the lesion is the confirmatory investigation which also a treatment tool. We report a case of middle-aged lady who had pyogenic granuloma of the tongue, which was safely excised using ultrasonic scissors. This case highlights the new technique of using ultrasonic instruments for excision of benign tongue lesion, with marked reduction of blood loss and operation time.

    Kok, T.C., Ong, S.T.
    Ann Dent, 2001;8(1):-.
    MyJurnal
    The purpose of this study is to assess the effectiveness of C02 laser in relieving symptoms associated with Oral lichen planus (aLP) and lichenoid lesions (aLL) and the event of healing. Six patients were selected for this study with 13 sites treated. Each lesion was ablated with C02 laser and the wound allowed to heal undisturbed. Prior to treatment, 4 patients had both unprovoked and provoked pain and 2 patients rated for provoked pain only. After laser ablation, five out of six patients treated recorded no pain / 0 pain score. One month post-laser, the treated area was almost the same colour as the surrounding normal mucosa and soft in texture in all but one patient in which there was some fibrosis and residual plaque-like patch. Weconclude that the use of C02 laser in the treatment of aLP and aLL shows positive results in relieving symptoms associated with these lesions.

  8. Fulltext The evaluation of Streptococcus mutans content of saliva in patients with recurrent oral ulceration
    Al-Ahmad, Basma Ezzat Mustafa, Muhannad Ali Kashmoola, Nur Aini Zakaria
    International Medical Journal Malaysia, 2017;16(21):14-14.
    MyJurnal
    Recurrent oral ulcer is a chronic inflammatory condition characterized by mucosa
    ulceration, which was believed to have bacterial etiology. Streptococcus mutans is one of the
    bacteria which have been implicated in this case; it is gram-positive bacteria that reside in the
    biofilms on the tooth surfaces. The aim of this study was to evaluate Streptococcus mutans content
    in saliva of recurrent oral ulcer patients and its role as a prognostic factor. (Copied from article).

  9. Argyrophilic nuclear organizer region and p73 expression in head and neck squamous cell carcinomas: Teammates or adversaries?
    Venkateswaran SP, Nathan LE, Mutalik VS, Shamsuddin NH
    J Oral Maxillofac Pathol, 2016 Sep-Dec;20(3):427-435.
    PMID: 27721608
    Head and neck squamous cell carcinoma (HNSCC) consists of squamous cell carcinomas (SCCs) arising in the upper aerodigestive tract and accounts for 5% of cancers worldwide. In Malaysia, cancers of the nasopharynx, larynx, tongue and oral cavity are among the top twenty most common cancers in men. Argyrophilic nuclear organizer regions (AgNORs) are increased from normal mucosa to premalignant lesions to malignant lesions and have been associated with tumor grade and prognosis of patients. Although p73 is not mutated in human cancers, high levels of p73 expression have been associated with tumor differentiation status and patient prognosis.

    MyJurnal
    Recently, epidermal mucus of fish has been identified as a rich biological source of various bioactive substances, particularly antibacterial peptides. This study was conducted to identify the potential of epidermal mucosa of Clarias batrachus as a source of antibacterial material. Mucosal samples were collected from C. batrachus epidermis and extracted using an aqueous extraction method. Antibacterial activity of the crude epidermal mucus extract was determined by using spectrophotometric method. As a result there was antibacterial activity by the mucus extract against Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853). The results of this study supports the role of mucus as a part of body immune system with antibacterial peptide as a component of innate body immune system. Hence, these findings can be used as one of the first steps towards the development of new class antibiotics.

    Pemphigus is a chronic mucocutaneous disease that initially manifests in the form of intraoral blisters which spread to other mucous membrane and skin. This study describes an unusual case of chronic generalized childhood pemphigus disease in an 11-year-old girl, who presented with multiple vesicles all over her body. Such a condition is seen more often in older people rather than children. It is crucial for dental professionals to be familiar with the diagnosis of bullous skin diseases in children and adolescents, especially in its initial stages in order to prevent the serious consequences and morbidity. The article highlights clinical presentation, histopathology, and successful management strategies useful for pediatric dental practice.

  12. Fulltext Isolation of Vaginal Epithelial Cells: In Preparation of Autologous Vaginal Tissue Lining for Congenital Absence of Vagina Patients
    Lih Yuan T, Sulaiman N, Nur Azurah AG, Maarof M, Razali RA, Koh B, et al.
    Int J Mol Sci, 2023 May 15;24(10).
    PMID: 37240142 DOI: 10.3390/ijms24108798
    Infertility is a condition affecting women who are born with an underdeveloped or absent vagina, a birth defect known as congenital absence of the vagina. It is a rare disorder where the development of the Mullerian duct is obstructed by unidentified causes. The case is seldom reported due to the low prevalence and sparse epidemiology studies worldwide. A potential solution for the disorder is neovaginal creation with in vitro cultured vaginal mucosa. Limited studies have reported its application, but none are reproducible or specific regarding the established processes for acquiring vaginal epithelial cells from vaginal biopsies. These research gaps were adequately answered with an epidemiology study of inpatient details in Hospital Canselor Tuanku Muhriz, Malaysia, established methods and outcomes of vaginal tissue processing and isolation, and characterization of vaginal epithelial cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and immunofluorescence assays. The reported evidence and speculation that the disorder arises because of a cellular transition event between epithelial and mesenchymal cells during the development of the Mullerian duct could be key in the creation of neovaginas using established culture procedures to improve surgical results and restore fertility.

    PMID: 25587561 DOI: 10.1155/2014/312670
    This study was conducted to record the histological features of the gastrointestinal tract of wild Indonesian shortfin eel, Anguilla bicolor bicolor (McClelland, 1844), captured in Peninsular Malaysia. The gastrointestinal tract was segmented into the oesophagus, stomach, and intestine. Then, the oesophagus was divided into five (first to fifth), the stomach into two (cardiac and pyloric), and the intestine into four segments (anterior, intermediate, posterior, and rectum) for histological examinations. The stomach had significantly taller villi and thicker inner circular muscles compared to the intestine and oesophagus. The lamina propria was thickest in stomach, significantly when compared with oesophagus, but not with the intestine. However, the intestine showed significantly thicker outer longitudinal muscle while gastric glands were observed only in the stomach. The histological features were closely associated with the functions of the different segments of the gastrointestinal tract. In conclusion, the histological features of the gastrointestinal tract of A. b. bicolor are consistent with the feeding habit of a carnivorous fish.

    Wong TW, Dhanawat M, Rathbone MJ
    Expert Opin Drug Deliv, 2014 Sep;11(9):1419-34.
    PMID: 24960192 DOI: 10.1517/17425247.2014.924499
    Vaginal infection is widespread and > 80% of females encounter such infections during their lives. Topical treatment and prevention of vaginal infection allows direct therapeutic action, reduced drug doses and adverse effects, convenient administration and improved compliance. The advent of nanotechnology results in the use of nanoparticulate vehicle to control drug release, to enhance dosage form mucoadhesive properties and vaginal retention, and to promote mucus and epithelium permeation for both extracellular and intracellular drug delivery.

  15. Histomorphology of the stomach, proventriculus and ventriculus of the red jungle fowl
    Kadhim KK, Zuki AB, Noordin MM, Babjee SM
    Anat Histol Embryol, 2011 Jun;40(3):226-33.
    PMID: 21443757 DOI: 10.1111/j.1439-0264.2010.01058.x
    The cranial chamber (proventriculus) and caudal chamber (ventriculus) of the stomach of the Red jungle fowl (Gallus gallus spadiceus) were examined by means of light microscopy. Both chambers presented folds of the tunica mucosa lined by a simple prismatic epithelium that was positive for neutral mucin. Simple tubular glands occupied the lamina propria of both chambers; in the ventriculus of older birds, they showed a coiled base. These ventricular glands were lined by simple cuboidal cells represented by the chief cells and a few large basal cells. The luminal and tubular koilin rodlets and folds of the ventriculus were positive to periodic acid Schiff (PAS) stain. The proventricular glands were situated between the inner and outer layers of the lamina muscularis mucosae. Cells lining the tubulo-alveolar units of the proventricular glands showed a dentate appearance. Vacuoles were not observed, and the cells were negative for Alcian-PAS stain. The tunica submucosa was very thin in the proventricular wall. In the ventriculus, it was not separated from the lamina propria owing to the absence of any lamina muscularis mucosae. The tunica muscularis of the proventriculus was formed by a thick inner layer of circular smooth muscle fibres and a thin outer layer of longitudinal fibres. In addition to these layers, oblique muscle fibres formed the most internal layer of the tunica muscularis in the ventriculus.

    A retrospective analysis of 182 HIV positive Malaysians was done in two centers, the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic and clinical data were analyzed. The analysis showed that 130 out of 182 patients had mucocutaneous disorders (71.4%). In the study there were 125 males (96.2%) and 5 females (3.8%). The majority of the patients were in the age group from 20 to 50 years. The patients who presented with mucocutaneous disease also had low CD4+ T lymphocyte counts, and most of them had AIDS defining illnesses. The number of cases with generalized hyperpigmentation was very high (35.7%), followed by papular eruptions (29.1%) and xerosis (27.5%). Seborrheic dermatitis was seen in 19.2% of the cases and psoriasis in 7.7%. The most common infections were oral candida 35.7%, tinea corporis and onychomycosis 9.9%, and herpes infection 4.3%. However, mucocutaneous manifestations of Kaposi's sarcoma were rare. The results suggested that mucocutaneous findings are useful clinical predictors of HIV infection or a sign of the presence of advanced HIV infection.

  18. Fulltext A case of recurrent respiratory papillomatosis successfully removed via endoscopic argon plasma coagulation (APC) with no evidence of recurrence
    Wong JL, Tie ST, Lee J, Kannan SK, Rashid Ali MR, Ibrahim A, et al.
    Med J Malaysia, 2014 Aug;69(4):195-6.
    PMID: 25500852 MyJurnal
    Recurrent respiratory papillomatosis (RRP) is a benign disease caused by the human papilloma virus (HPV), characterized by the formation of recurrent, epithelial neoplastic lesions in the airways. While benign, they can cause significant airway obstruction in some cases. Difficulties in treatment arise from the recurrent nature of the lesions despite repeated procedures. Other known procedures that result in deep tissue damage also cause unacceptable collateral damage to the underlying airway mucosa. We describe a case of recurrent papillomatosis that was successfully treated with argon plasma coagulation ( APC) when laser and electrocautery ablation had failed in the past. After the papillomatasis was treated with APC, there is no recurrence on repeat scope at 4 months and 9 months after the initial procedure. The procedure was done as a day case and there is no complication from the procedure. The property of the APC that allows it to cause only superficial thermal damage to the tissue makes it a suitable adjunct therapy to the treatment of papillomas, which are usually superficial lesions.

  19. Fulltext Inflammatory Bowel Disease-related Colorectal Cancer in the Asia-Pacific Region: Past, Present, and Future
    Zhiqin W, Palaniappan S, Raja Ali RA
    Intest Res, 2014 Jul;12(3):194-204.
    PMID: 25349593 DOI: 10.5217/ir.2014.12.3.194
    Patients with inflammatory bowel disease (IBD) are at an increased risk of developing colorectal cancer (CRC), and key contributing factors include chronic colonic inflammation and the extent and duration of disease. This increase in risk is more likely to result from chronic inflammation of the colonic mucosa than from any clearly defined genetic predisposition. However, globally, the true magnitude of this risk is debatable, since results from different studies are heterogeneous in terms of geographical and methodological variables. The prevalence of IBD-related CRC in the Asia-Pacific region ranges from 0.3% to 1.8% and a recent study found that the cumulative incidence of IBD-related CRC is comparable to that in Western countries. However, the CRC mortality rate in the Asia-Pacific region is on the rise compared with that in Western countries, and a few Asian countries show particularly rapid upward trends in CRC incidence. Although our understanding of the molecular and clinical basis for IBD-related CRC has improved substantially, our means of prevention, endoscopic surveillance, chemoprevention, and prophylactic surgery remain modest at best. Furthermore, published data on IBD-related CRC in the Asia-Pacific region is lacking, and this review addresses many aspects including epidemiology, natural history, etiopathogenesis, morphology, and biological behaviors of IBD-related CRC and sporadic CRC in the Asia-Pacific region. In this review, we will also discuss the risk factors for CRC in IBD patients, endoscopic technology screening, and surveillance programs and management strategies for IBD-related CRC.

  20. Fulltext Maxillary Sinus Mucopyocele in a Fifty-eight-year-old man: A Possible Late Complication of Irradiation to Head and Neck
    Sharouny H, Narayanan P
    Iran Red Crescent Med J, 2014 Jul;16(7):e17133.
    PMID: 25237579 DOI: 10.5812/ircmj.17133
    INTRODUCTION: A mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. Mucopyocele is an infected mucocele.

    CASE REPORT: We presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. Computed tomography scan showed opacification of the left maxillary sinus expanding through the medial wall of the antrum with thinning and destruction of the adjacent structures. Endoscopic marsupialization of the lesion and left partial maxillectomy were performed. The cystic mass had yellowish thick mucopurulent fluid that was completely drained.

    CONCLUSIONS: A few cases of sphenoid sinus mucocele as a late complication of radiation therapy have been reported. Maxillary mucocele and mucopyocele can be considered as one of the late complications of radiotherapy to head and neck as a result of occlusion of sinus ostia by scarred mucosa.
