Lip Print Analysis in Malaysian Chinese Population (Klang Valley): Lipstick-Cellophane Tape Technique (Analisis Cap Bibir Populasi Cina Malaysia di Lembah Klang: Teknik Gincu-Pita Selofan) / Jurnal Sains Kesihatan Malaysia

@#Cheiloscopy is recognized as a tool for personal identification due to its strength in criminalistics. In this study, the lip print of Malaysian Chinese population in Klang Valley was used for gender determination using lipstick-cellophane technique. 412 subjects (203 males and 209 females) were selected conveniently. Lipstick was first applied on the lips and the lip print was lifted using cellophane tape prior to pasting them onto a plain A4 paper and analysis using magnifying glass. Six topography areas of lip prints were classified using Suzuki and Tsuchihashi’s classification, including upper left, upper middle, upper right, lower right, lower middle and lower left. Chi-square test showed that all lip sections were significantly different from each other (p < 0.05). Type II was the dominant pattern in four lip sections for both genders: upper left (male 81.3%, female 57.4%), upper right (male 71.9%, female 42.9%), lower left (male 98.0%, female 90.0%) and lower right (male 96.1%, female 86.1%). Type IV was the dominant pattern for both middle part of the lips; upper middle (male 56.2%, female 50.7%) and lower middle (male 62.6%, female 50.2%). The results showed that gender can be differentiated based on lip print patterns. This finding suggested that cheiloscopy could be used in aiding personal identification for forensic investigation.

Digital Approach for Lip Prints Analysis in Malaysian Malay Population (Klang Valley): Photograph on Lipstick-Cellophane Tape Technique / Jurnal Sains Kesihatan Malaysia

@#Personal identification in forensic investigation is not an easy process. Lip print analysis is one of the techniques that can be used to assist in human identification. This study was conducted to investigate the sex based on lip print pattern among Malaysian Malay population in Klang Valley, using photograph on lipstick-cellophane tape technique and the Suzuki and Tsuchihashi classification. A total of 360 subjects (180 males and 180 females) aged 15 and above were included in this study. The lip print was taken by pressing a cellophane tape to the lipstick applied on lip, pasted it onto a plain A4 paper and then photographed using a smart phone camera (OPPO F1). The images were then analysed using Adobe Photoshop software. A lip print image were divided into six sections: upper left, upper middle, upper right, lower right, lower middle and lower left. The Pearson chi-square test showed that there are significant differences between sexes in each section except for the upper middle section. Type V (irregular pattern) was the dominant pattern for the upper left, upper right, lower right and lower left sections (ranging from 71.1% to 86.7% for males and 80.6% to 83.9% for females) while type IV (reticular pattern) was mostly found in upper middle and lower middle section. Malaysian female displayed type V as the dominant lip print pattern in every section (ranging from 39.4% to 83.9%) except upper middle section and for Malaysian male, type V dominated the lip print pattern in all section (ranging from 71.1% to 86.7%) except for the upper and lower middle section. The result of this study can be applied in assisting the human identification for forensic science investigation.

Determinación de plomo en lápices labiales de diferentes marcas comercializados en Lima / Determination of plumb in lip pencils of different commercial marks in Lima

Objetivo: Determinar la presencia de plomo en los lápices labiales de diferentes marcas que se expenden en la ciudad de Lima. Material y Método: Se utilizó 24 lápices labiales de cinco marcas comerciales operantes en Perú, procedentes del centro comercial Capón en Lima. La presencia de plomo se determinó por el método de espectrofotometría de absorción atómica con horno de grafito. Para la validación estadística, se determinó la media y la desviación estándar. Resultados: Se encontró mayor contenido de plomo en las marcas LAL-04-YHBC (3,02 ppm), LAL-05-BALOE (2,10 ppm), LAL- 02-RW (1,55 ppm) y LAL-03-VCYH (1,22 ppm); contrastada con una marca poco conocida,de código LAL-01-CHOCO PLUSII en la que no se detectó plomo. Conclusiones: De los lápices labiales estudiados, cuatro de ellos superaron los valores permisibles de plomo (0,1 ppm), que es un valor referencial para caramelos.

Objective: To determine the presence of lead in lipsticks from different brands that are sold in the city of Lima. Material and Methods: 24 lipsticks of five different trademarks were used, from the shopping center in Lima Capon. The presence of lead was determined by the method of atomic absorption spectrophotometry with graphite furnace. For statistical validation, the mean and standard deviation was determined. Results: The highest lead content was found in the LAL -04 - YHBC (3.02 ppm) , LAL -05 - BALOE (2.10 ppm) , LAL -02 -RW (1.55 ppm) and LAL -03 marks - VCYH (1.22 ppm ) ; contrasted with a little known brand , LAL -01- CHOCO PLUSII code where no lead was detected. Conclusions: Of the studied lipsticks, four exceeded the permissible values of lead (0.1 ppm), which is a reference value for candy.

A Case of Allergic Contact Cheilitis from Propyl Gallate / 대한피부과학회지

Propyl gallste and other gallic acid esters are used as antioxidants in lipsticks, lip balms and salves, cosmetic creams and lotions, bakery products, edible fats and other pharmaceutical and industrial products. Propyl gallate is used widely but allergic contact dermatits from propyl gallate is rare. A 44-year-old female patient had pruritic multiple tiny erythematous papules and vesicles on the margin of her lip for a week. We found that the causative material of the allergic contact cheilitis was propyl gallate. We proved it with a patch test, provocation use test and quantitative and qualitative analysis of the lipstick. To our knowledge, this is the first case report of lipstick allergic contact cheilitis from propyl gallate in Korean literature.

Six Cases of Allergic Contact Cheilitis / 대한피부과학회지

The vermilion border of the lips has a modifed epithelium, which is much more likely to develop allergic contact sensitivity reactions than oral mucosa. Allergens in contact with both the oral mucosa and the lips oftens produce only cheilitis. Allergic contact cheilitis may result from topical medicaments, dentifrices, cosmetics, foods, plants or metals. We present six cases of allergic contact cheilitis confirmed by patch test. The toot4paste was incriminated in 2 cases, the lipstick in 3 cases and the bubble gum in one rase as producing chelitis respectively.
