Filigree burn of lightning: two case reports

Kumar V

Med Sci Law, 2007 Apr;47(2):171-3.
PMID: 17520964

Lightning is a powerful natural electrostatic discharge produced during a thunderstorm. The electric current passing through the discharge channels is direct with a potential of 1000 million volts or more. Lightning can kill or injure a person by a direct strike, a side-flash, or conduction through another object. Lightning can cause a variety of injuries in the skin and the cardiovascular, neurological and ophthalmic systems. Filigree burn of lightning is a superficial burn and very rare. Two cases of death from lightning which have this rare finding are reported and discussed.

Fulltext Impact of childhood burn injuries on breastfeeding: a case report

Arabi Z, Md Monoto EM, Bojeng A

Background: Pre-pubescent girls with chest burns are at risk of complication associated with scarring and impairment in breast development. This case illustrates how burn injuries in childhood in a first-time mother have affected her in terms of breastfeeding.
Case presentation: In May 2015, a 20 year old first-time mother at 36 weeks gestation was seen in a district health clinic in Kuching, Sarawak in regards to her ability to breastfeed. She had a history of a flame burn at the age of 5 years old to her chest, abdomen, upper limb and part of her trunk. A skin graft was done on her whole chest and abdomen. Despite the injuries, she had pubertal and antenatal breast development. Her abdomen was able to stretch to accommodate her pregnancy. Physical examination showed a pregnancy which corresponded to date. The skin over her chest and abdomen appeared tight with areas of hyperpigmentation and hypopigmentation due to scarring from the skin graft. Breast tissues were palpable over her chest. The areola and nipple tissue were completely absent with complete scarring of the nipple-areolar complex. There was no duct opening to the areola for milk expression or leakage. Counselling regarding her breastfeeding issues was done. She delivered her baby at full term via spontaneous vaginal delivery with no complication. Oral cabergoline 1 mg was given on the first day postpartum. The baby was given infant formula via bottle feeding as the feeding method of choice.
Conclusion: Counselling plays an important part in the management of a mother with breastfeeding difficulty. Allaying the possible guilty feelings of not being able to breastfeed will fulfil the emotional gap which may arise in a mother with these challenges.

Characterization of collagen/chitosan films for skin regenerating scaffold

Ismarul IN, Ishak Y, Ismail Z, Mohd Shalihuddin WM

Med J Malaysia, 2004 May;59 Suppl B:57-8.
PMID: 15468817

Various proportions of chitosan/collagen films (70/30% to 95/05%) w/w were prepared and evaluated for its suitability as skin regenerating scaffold. Interactions between chitosan and collagen were studied using Fourier Transform Infrared spectroscopy (FTIR) and Differential Scanning Colorimetry (DSC). Scanning Electron Microscope (SEM) was used to investigate the morphology of the blend. Mechanical properties were evaluated using a Universal Testing Machine (UTM). The chitosan/collagen films were found to swell proportionally with time until it reaches equilibrium. FTIR spectroscopy indicated no chemical interaction between the components of the blends. DSC data indicated only one peak proving that these two materials are compatible at all proportions investigated. SEM micrographs also indicated good homogeneity between these two materials.

The development of a tool to predict temperature-exposure of incinerated teeth using colourimetric and hydroxyapatite crystal size data

Rahmat RA, Humphries MA, Austin JJ, Linacre AMT, Self P

Int J Legal Med, 2021 Sep;135(5):2045-2053.
PMID: 33655354 DOI: 10.1007/s00414-021-02538-7

This study presents a novel tool to predict temperature-exposure of incinerated pig teeth as a proxy for understanding impacts of fire on human teeth. Previous studies on the estimation of temperature-exposure of skeletal elements have been limited to that of heat-exposed bone. This predictive tool was developed using a multinomial regression model of colourimetric and hydroxyapatite crystal size variables using data obtained from unheated pig teeth and teeth incinerated at 300 °C, 600 °C, 800 °C and 1000 °C. An additional variable based on the observed appearance of the tooth was included in the tool. This enables the tooth to be classified as definitely burnt (600 °C-1000 °C) or uncertain (27 °C/300 °C). As a result, the model predicting the temperature-exposure of the incinerated teeth had an accuracy of 95%. This tool is a holistic, robust and reliable approach to estimate temperature of heat-exposed pig teeth, with high accuracy, and may act as a valuable proxy to estimate heat exposure for human teeth in forensic casework.

Skin is the largest organ in human system and plays a vital role as a barrier against environment and pathogens. Skin regeneration is important in tissue engineering especially in cases of chronic wounds. With the tissue engineering technology, these skins equivalent have been use clinically to repair burns and wounds. Consented redundant skin samples were obtained from patients aged 9 to 65 years old. Skin samples were digested with dispase, thus separating the epidermis and the dermis layer. The epidermis layer was trypsinized and cultured in DKSFM in 6-well plate at 37 degrees C and 5% CO2. Once confluent, the culture were trypsinized and the cells were pooled. Cells were counted using haemacytometer. Doubling time and viability were calculated and analysed. From the result, we conclude that doubling time and viability of in vitro keratinocytes cultured in DKSFM media is not age dependant.
