Ahmad Fadzil MH, Ihtatho D, Mohd Affandi A, Hussein SH

J Med Eng Technol, 2009;33(7):516-24.
PMID: 19639508 DOI: 10.1080/07434610902744074

Skin colour is vital information in dermatological diagnosis as it reflects the pathological condition beneath the skin. It is commonly used to indicate the extent of diseases such as psoriasis, which is indicated by the appearance of red plaques. Although there is no cure for psoriasis, there are many treatment modalities to help control the disease. To evaluate treatment efficacy, the current gold standard method, PASI (Psoriasis Area and Severity Index), is used to determine severity of psoriasis lesion. Erythema (redness) is one parameter in PASI and this condition is assessed visually, thus leading to subjective and inconsistent results. Current methods or instruments that assess erythema have limitations, such as being able to measure erythema well for low pigmented skin (fair skin) but not for highly pigmented skin (dark skin) or vice versa. In this work, we proposed an objective assessment of psoriasis erythema for PASI scoring for different (low to highly pigmented) skin types. The colour of psoriasis lesions are initially obtained by using a chromameter giving the values L*, a*, and b* of CIELAB colour space. The L* value is used to classify skin into three categories: low, medium and highly pigmented skin. The lightness difference (DeltaL*), hue difference (Deltah(ab)), chroma (DeltaC*(ab)) between lesions and the surrounding normal skin are calculated and analysed. It is found that the erythema score of a lesion can be distinguished by their Deltah(ab) value within a particular skin type group. References of lesion with different scores are obtained from the selected lesions by two dermatologists. Results based on 38 lesions from 22 patients with various level of skin pigmentation show that PASI erythema score for different skin types i.e. low (fair skin) to highly pigmented (dark skin) skin types can be determined objectively and consistent with dermatology scoring.

Fulltext Efficacy of chitosan derivative films versus hydrocolloid dressing on superficial wounds

Halim AS, Nor FM, Mat Saad AZ, Mohd Nasir NA, Norsa'adah B, Ujang Z

J Taibah Univ Med Sci, 2018 Dec;13(6):512-520.
PMID: 31435371 DOI: 10.1016/j.jtumed.2018.10.004

Objectives: Chitosan, the N-deacetylated derivative of chitin, has useful biological properties that promote haemostasis, analgesia, wound healing, and scar reduction; chitosan is bacteriostatic, biocompatible, and biodegradable. This study determined the efficacy of chitosan derivative film as a superficial wound dressing.
Methods: This multicentre randomised controlled trial included 244 patients, of whom 86 were treated with chitosan derivative film and 84 with hydrocolloid. The percentage of epithelisation, as well as patient comfort, clinical signs, and patient convenience in application and removal of the dressings were assessed.
Results: The primary outcome of this study was the percentage of epithelisation. Except for race (p = 0.04), there were no significant differences between groups in sex, age, antibiotic usage, or initial wound size (p > 0.05). There was no significant difference in the mean epithelisation percentage between groups (p = 0.29). Patients using chitosan derivative film experienced more pain during removal of dressing than those in the hydrocolloid group (p = 0.007). The chitosan derivative film group showed less exudate (p = 0.036) and less odour (p = 0.024) than the control group. Furthermore, there were no significant differences between groups in terms of adherence, ease of removal, wound drainage, erythema, itchiness, pain, and tenderness. No oedema or localised warmth was observed during the study.
Conclusion: This study concluded that chitosan derivative film is equivalent to hydrocolloid dressing and can be an option in the management of superficial and abrasion wounds.

MyJurnal

Haemophagocytic lymphohistiocytosis (HLH) is a clinico-pathologic entity caused by increased proliferation
and activation of benign macrophages with haemophagocytosis throughout the reticulo-endothelial system.
Virus-associated HLH is a well-recognised entity. Although majority of parvovirus B19 associated HLH does not
require any specific treatment and carries good prognosis, outcome of children is worse than adults. We report
here a case of HLH associated with acute parvovirus B19 infection in a young healthy patient with underlying
hereditary spherocytosis, with bone marrow findings typical of parvovirus infection. Although this patient
had spontaneous recovery of cell counts, he succumbed due to complication from prolonged ventilation.
Unexpectedly, his immunoglobulin levels were inappropriately normal despite on-going ventilator associated
pneumonia, which reflects inadequate humoral immune response towards infection.

Rajinikanth PS, Chellian J

Int J Nanomedicine, 2016 Oct 5;11:5067-5077.
PMID: 27785014

The aim of this study was to develop a nanostructured lipid carrier (NLC)-based hydrogel and study its potential for the topical delivery of 5-fluorouracil (5-FU). Precirol(®) ATO 5 (glyceryl palmitostearate) and Labrasol(®) were selected as the solid and liquid lipid phases, respectively. Poloxamer 188 and Solutol(®) HS15 (polyoxyl-15-hydroxystearate) were selected as surfactants. The developed lipid formulations were dispersed in 1% Carbopol(®) 934 (poly[acrylic acid]) gel medium in order to maintain the topical application consistency. The average size, zeta potential, and polydispersity index for the 5-FU-NLC were found to be 208.32±8.21 nm, -21.82±0.40 mV, and 0.352±0.060, respectively. Transmission electron microscopy study revealed that 5-FU-NLC was <200 nm in size, with a spherical shape. In vitro drug permeation studies showed a release pattern with initial burst followed by sustained release, and the rate of 5-FU permeation was significantly improved for 5-FU-NLC gel (10.27±1.82 μg/cm(2)/h) as compared with plain 5-FU gel (2.85±1.12 μg/cm(2)/h). Further, skin retention studies showed a significant retention of 5-FU from the NLC gel (91.256±4.56 μg/cm(2)) as compared with that from the 5-FU plain gel (12.23±3.86 μg/cm(2)) in the rat skin. Skin irritation was also significantly reduced with 5-FU-NLC gel as compared with 5-FU plain gel. These results show that the prepared 5-FU-loaded NLC has high potential to improve the penetration of 5-FU through the stratum corneum, with enormous retention and with minimal skin irritation, which is the prerequisite for topically applied formulations.

Fulltext Occupational and Environmental Risk Factors Influencing the Inducement of Erythema among Nigerian Laboratory University Workers with Multiple Chemical Exposures

Reuben U, Ismail AF, Ahmad AL, Maina HM, Daud A

Int J Environ Res Public Health, 2019 04 13;16(8).
PMID: 31013942 DOI: 10.3390/ijerph16081334

: The chemicals from laboratories pose a significant risk forinducing erythema, an abnormal redness of the skin, as a result of poor occupational and environmental factors that promote hypersensitivity to a chemical agent. The aim of this present study was to determine the occupational and environmental risk factors influencing the inducement of erythema in laboratory workers due to exposure to chemicals. This was a cross-sectional study on a population-based sample of Nigerian university laboratory workers. Data were collected using the erythema index meter and an indoor air control meter. The study included 287 laboratory workers. The laboratory workers who properly used personal protective equipment (PPE) were 60% less likely to have induced erythema (adjusted odds ratio (AOR) = 0.40; 95% confidence interval CI: 0.22-0.77; probability value p = 0.011). The chemical mixture exceeding the permissible exposure limit (PEL) was found to have a small effect in inducing the erythema (AOR = 4.22; 95%CI: 2.88-12.11; p = 0.004). Most of the sampled laboratories where the respondents worked had unsuitable temperatures (AOR = 8.21; 95% CI: 4.03-15.01; p = 0.001). Erythema was more frequently found in the respondents who spent 4-5h in the laboratory (AOR = 3.11; 95%CI: 1.77-9.23; p = 0.001). However, high levels of ventilation reduce the likelihood of erythema in a laboratory by 82% (0.18). Multiple logistic regressions revealed that PPE, PEL, exposure time, temperature, and ventilation were the probable predictive factors associated with the inducement of erythema. Providing better educational knowledge and improving the attitude towards hazards and safety in a laboratory would lead to reduced rates of new cases.

Erythema multiforme, Stevens-Johnson syndrome and toxic epidermal necrolysis in northeastern Malaysia

Kamaliah MD, Zainal D, Mokhtar N, Nazmi N

Int J Dermatol, 1998 Jul;37(7):520-3.
PMID: 9679693

BACKGROUND: Previous studies have reported that drugs and infections are common causes of erythema multiforme (EM) and Stevens-Johnson syndrome (SJS). Toxic epidermal necrolysis (TEN) is mainly related to drugs. No study has been conducted in Kelantan, the northeastern state of Malaysia, to assess these cutaneous reactions.
METHODS: A retrospective study of all hospitalized cases of EM, SJS, and TEN was conducted covering an 8-year period from 1987 to 1994.
RESULTS: There were four cases (13.8%) of EM, 22 cases (75.9%) of SJS, and three cases (10.3%) of TEN. Drugs as a definitive cause was observed in one case (25%) of EM, 12 cases (54.5%) of SJS, and two cases (66.7%) of TEN. Drugs as a probable cause was observed in seven cases (31.8%) of SJS and one case (33.3%) of TEN. The male to female ratio was equal in EM and SJS. Antiepileptics were the commonest culprits, followed by antibiotics. One patient died of SJS and one patient died of TEN, giving mortality rates of 4.5% and 33.5% respectively. Fever was noted in 18 patients (62.1%). Leukocytosis was noted in 10 patients (34.5%), and nine patients (31.0%) had elevated liver transaminase enzymes. No significant correlation was noted between these biochemical changes and cutaneous eruption. Secondary infections were observed in 11 patients (37.9%): Staphylococcus aureus was the commonest isolated organism.
CONCLUSIONS: This study shows that drugs remain the commonest culprit in SJS and TEN. Despite adequate treatment, the mortality rate remains high, especially in TEN. These findings are similar to those of other reported studies.

Background: Peripheral venous catheterisation is indispensable in modern practise of medicine. The indications of venous access should be weighed against the risk of complications, the commonest being thrombophlebitis. Thrombophlebitis causes patient discomfort and the need for new catheter insertion and risk of developing further widespread infections. Methodology: This observational study was conducted on adult patients admitted to the surgical and medical ward of a tertiary hospital in Negeri Sembilan Malaysia in 2011. Four researchers visited patients daily and examined for signs of thrombophlebitis; warmth, erythema, swelling, tenderness or a palpable venous cord. Risks factors that were studied in this research were patient/s age and gender, duration of catheterization, use of catheter for infusion, size of catheter, site of catheter insertion and types of infusate. Thrombophlebitis was graded using a scale adapted from Bhandari et al. (1979). Results: In total, 428 patients were recruited with an incidence rate of thrombophlebitis of 35.2%. Among those who developed thrombophlebitis, 65% had mild thrombophlebitis, 19% moderate and 8% severe thrombophlebitis. Results showed that female patients had a significant increased risk of developing thrombophlebitis. Also risk increased significantly with increased duration of catheterization and usage of the catheter for infusion. The age of a patient, types of infusate use, size of catheter and site of catheter insertion did not significantly influence the development of thrombophlebitis. Conclusion: The study showed that risk of developing thrombophlebitis is significantly increased among female patients, and also with increased duration of catheterization and use of the peripheral venous catheter for infusion. We recommended elective replacement of catheter every 72 hours and daily examination of catheters for signs of thrombophlebitis by a healthcare personnel.

Objective: We presented a case report, systemic lupus erythematosus (SLE) in a Malay boy. Interestingly, this case occurs in a boy, which is not so common because autoimmune disease usually occurs in female. Design: Case report. Methods: We highlighted a case of a boy with SLE who presented with clinical symptoms suggestive of SLE and fulfilled the criteria for SLE diagnosis. Results: The patient was successfully managed with antihypertensive, intravenous cyclophosphamide and oral prednisolone and respond well to the therapy. Conclusion: Systemic lupus erythematosus is a chronic autoimmune disease which rarely occurs in male. However we reported one such case which fulfilled the criteria for SLE. © 2017 Japan Health Sciences University & Japan International Cultural Exchange Foundation.

Extraction of gelatin using traditional acid-base pretreatment method has several limitations
such as time consuming and causes serious water pollution. Chemical treatment often being used
as an alternative process to overcome the weaknesses of the conventional method. However,
excessive chemical elements would damage the structure of the gelatin due to its high sensitivity
to the acid content. High Pressure Processing (HPP) is a novel and environmental friendly
method that has been suggested to assist gelatin extraction. Pressurization during pretreatment
could reduce the extraction time and amount of acid used. It also has a potential in enhancing the
properties of the gelatin extract and increasing the gelatin yield. In this research, One-Factor-
at-Time (OFAT) and optimization study were done to determine the optimum parameters for
extraction of gelatin assisted by HPP from red tilapia skin. Four parameters; applied pressure,
pressure holding time, ratio of acid to skin and extraction time have been selected for the OFAT
design and concentration of the gelatin extract and percentage of yield gelatin were evaluated.
From OFAT, optimum technical parameters for response surface optimization design were 250
MPa pressure, 7.5 ml of acid to 1 g of skin and 12 hours extraction time. Pressure holding
time was fixed for 10 min. FCCCD has been used for optimization study. Results from the
data shows that the optimum conditions for gelatin extraction from red tilapia skin were 250
MPa for pressure, 10 min of pressure holding time, 7.5 ml of acid for 1 g of skin and 12 hours
of extraction time while the maximum concentration and yield were 19.51 mg/ml and 32.04%
(320.4 mg/g), respectively. These findings proved that HPP could increase the concentration
and the yield of the gelatin while reducing the chemical waste and shortening the extraction
process.

Fulltext Skin Color Preferences in a Malaysian Chinese Population

Tan KW, Stephen ID

Front Psychol, 2019;10:1352.
PMID: 31275195 DOI: 10.3389/fpsyg.2019.01352

Facial skin color influences the perceived health and attractiveness of Caucasian faces, and has been proposed as a valid cue to aspects of physiological health. Similar preferences for skin color have previously been found in African participants, while different preferences have been found among mainland Chinese participants. Here, we asked Malaysian Chinese participants (ethnic Chinese living in an Asian country with high levels of exposure to Western culture) to manipulate the skin color of Malaysian Chinese, Caucasian, and African faces to make them "look as healthy as possible." Participants chose to increase skin yellowness to a greater extent than to increase skin redness to optimize healthy appearance. The slight reduction in skin lightness chosen was not statistically significant after correction for multiple comparisons. While broadly in line with the preferences of Caucasian and African participants from previous studies, this differs from mainland Chinese participants. There may be a role for culture in skin color preferences, though methodological differences mean that further research is necessary to identify the cause of these differences in preferences.

PMID: 28239351 DOI: 10.3389/fphar.2017.00030

Spontaneous adverse drug reactions (ADRs) reporting is a useful source of drug safety information in infants as only adult patients are routinely tested in clinical trials. This study was aimed to evaluate the spontaneously reported ADRs using WHO Adverse Reaction Terminology and to identify the common drugs associated with ADRs in children under 2 years of age. A retrospective analysis of ADR data for children below 2 years old from 2000 to 2013 was conducted using the data extracted from Malaysia's national pharmacovigilance database, QUEST2 System. From 2000 to 2013, Malaysia's National Pharmaceutical Control Bureau received a total of 11,932 reports for children from various healthcare facilities in Malaysia. 14.0% (n = 1667) of the ADRs reported for those children were related to children under 2 years old. The data retrieved was analyzed in terms of age, gender, source of reporting, type of reporters, suspected medicines and characteristics of ADRs (category, onset, severity, and outcomes). A total of 1312 ADRs reported in 907 ADR reports were analyzed. The most common ADRs reported were skin appendage disorders (60.1%), and the most frequently reported symptoms were rash (n = 215), maculopapular rash (n = 206), urticaria (n = 169), erythematous rash (n = 76), and pruritus (n = 58). In general, drugs from antibacterials for systemic use (58.8%) appeared to be the most common contributors to ADRs in children below 2 years old. Penicillins and other β-Lactam Antibacterials accounted for more than 40% of all drugs implicated in ADRs. The majority of ADRs were subacute reactions that occurred within 24 h of exposure to the drug. A high proportion of ADRs was classified as mild, and most victims had no sequela. Only one fatality was seen. There were 10 cases for each symptom, namely erythema multiforme and Stevens-Johnson Syndrome, observed in this study. A large proportion of ADRs in children under 2 years old were mainly caused by drugs from antibacterial for systemic use, with most of the ADRs manifesting in skin reactions. This study also reveals rare cutaneous ADRs experienced by Malaysian children under the age of 2, which constitutes a crucial cause of harm among children.

Fulltext A pilot study: the efficacy of virgin coconut oil as ocular rewetting agent on rabbit eyes

Mutalib HA, Kaur S, Ghazali AR, Chinn Hooi N, Safie NH

Evid Based Complement Alternat Med, 2015;2015:135987.
PMID: 25802534 DOI: 10.1155/2015/135987

Purpose. An open-label pilot study of virgin coconut oil (VCO) was conducted to determine the safety of the agent as ocular rewetting eye drops on rabbits. Methods. Efficacy of the VCO was assessed by measuring NIBUT, anterior eye assessment, corneal staining, pH, and Schirmer value before instillation and at 30 min, 60 min, and two weeks after instillation. Friedman test was used to analyse any changes in all the measurable variables over the period of time. Results. Only conjunctival redness with instillation of saline agent showed significant difference over the period of time (P < 0.05). However, further statistical analysis had shown no significant difference at 30 min, 60 min, and two weeks compared to initial measurement (P > 0.05). There were no changes in the NIBUT, limbal redness, palpebral conjunctiva redness, corneal staining, pH, and Schirmer value over the period of time for each agent (P > 0.05). Conclusion. VCO acts as safe rewetting eye drops as it has shown no significant difference in the measurable parameter compared to commercial brand eye drops and saline. These study data suggest that VCO is safe to be used as ocular rewetting agent on human being.
