1.Anterolateral thigh free flap in reconstruction of oral cavity malignancy: UMMC experience
Journal of University of Malaya Medical Centre 2008;11(1):33-36
Oral cavity malignancy reconstructive surgery has advanced from pedicle fl aps to
microvascular free tissue transfer. Previously, reconstruction of these defects were done using radial
forearm free fl ap in this centre. We report our experience using anterolateral thigh free fl ap in a 49
year old lady with squamous cell carcinoma of the tongue. Excision of tumour left a defect which was
later reconstructed using microvascular free tissue transfer using the right anterolateral thigh free fl ap.
The fl ap was well taken up at the recepient site and no evidence of fl ap failure noted post operatively
and on completion of radiotherapy. She was able to maintain comprehensible speech and swallowing
ability.

Introduction: Diabetes is common among the elderly and can significantly affect their lives
including the issues related with social support and diabetic self-care activities.
Objectives: The objective of this study was to examine the social support and self-care activities
among the elderly patients with diabetes.
Methods: A survey involving 200 patients was conducted from March 2013 to May 2013 in
three hospitals in Kelantan. Data were obtained through self-administered questionnaires and
clinical characteristics were acquired from the patients’ records.
Results: The scores for social support (mean = 19.26; SD = 2.63) and self-care activities (mean
= 14.83; SD = 4.92) were moderate. Higher social support was associated with high levels of
glycated haemoglobin (HbA1c), fasting blood sugar (FBS) level, the duration of diabetes and
a decrease in body mass index (BMI) (p<0.05). It was observed that the patients with low
educational, Hb1Ac and FBS level, with other chronic diseases and who have had diabetes for
some time had low self-care activities (p<0.05). There was a significant negative relationship
between an increase in social support and decrease in self-care activity (p<0.05).
Conclusion: Healthcare providers, family and friends have to strengthen their relationship with
the elderly patients with diabetes to provide more social support and promote the compliance
with diabetic self-care activities to improve clinical outcomes.

Sjörgren’s syndrome is an uncommon chronic autoimmune disorder that affects exocrine glands. Sialolithiasis is an obstructive salivary gland disease which is also uncommon in the parotid salivary gland. The existing literature has documented the occurrence of multiple calcifications within the parenchyma of the parotid glands in patients with Sjörgren’s syndrome. This report describes the first case of right parotid duct solitary sialolith formation in a 64 year old female patient with Sjörgren’s syndrome. Whether the salivary stone encountered in this case represents an oral manifestation of Sjörgren’s syndrome or is just a co-incidental finding was discussed.

Using a UHPLC-TOF/MS method combined with software of Masslynx V4.1 and database in the literatures, a total of 20 polygala oligosaccharide esters (POEs) were identified in 60% ethanol extract of Kai Xin San (KXS-60%E). Furthermore, 14 POEs as well as 4 POE-metabolites were identified in rat plasma. The results revealed that POEs and POE-metabolites which were identified in rat plasma, were key components in KXS-60%E and the potential bioactive compounds for KXS action in the treatment of AD.

Background and Objectives:
Cigarette smoking is a major risk factor for atherosclerosis.Nicotine, a crucial constituent of tobacco, contributes to atherosclerosis development and progression. However, evidence of the association between nicotine and neointima formation is limited. We aimed to evaluate whether nicotine enhances neointimal hyperplasia in the native epicardial coronary arteries of pigs after percutaneous coronary intervention (PCI) with drug-eluting stents (DES).
Methods:
After coronary angiography (CAG) and quantitative coronary angiography (QCA), we implanted 20 DES into 20 pigs allocated to 2 groups: no-nicotine (n=10) and nicotine (n=10) groups. Post-PCI CAG and QCA were performed immediately. Follow-up CAG, QCA, optical coherence tomography (OCT), and histopathological analyses were performed 2 months post-PCI.
Results:
Despite intergroup similarities in the baseline QCA findings, OCT analysis showed that the nicotine group had a smaller mean stent and lumen areas, a larger mean neointimal area, greater percent area stenosis, and higher peri-strut fibrin and inflammation scores than the no-nicotine group. In immunofluorescence analysis, the nicotine group displayed higher expression of CD68 and α-smooth muscle actin but lower CD31 expression than the no-nicotine group.
Conclusions
Nicotine inhibited re-endothelialization and promoted inflammation and NIH after PCI with DES in a porcine model.

DNA barcoding without assessing reliability and validity causes taxonomic errors of species identification, which is responsible for disruptions of their conservation and aquaculture industry. Although DNA barcoding facilitates molecular identification and phylogenetic analysis of species, its availability in clariid catfish lineage remains uncertain. In this study, DNA barcoding was developed and validated for clariid catfish. 2,970 barcode sequences from mitochondrial cytochrome c oxidase I (COI) and cytochrome b (Cytb) genes and D-loop sequences were analyzed for 37 clariid catfish species. The highest intraspecific nearest neighbor distances were 85.47%, 98.03%, and 89.10% for COI, Cytb, and D-loop sequences, respectively. This suggests that the Cytb gene is the most appropriate for identifying clariid catfish and can serve as a standard region for DNA barcoding. A positive barcoding gap between interspecific and intraspecific sequence divergence was observed in the Cytb dataset but not in the COI and D-loop datasets. Intraspecific variation was typically less than 4.4%, whereas interspecific variation was generally more than 66.9%. However, a species complex was detected in walking catfish and significant intraspecific sequence divergence was observed in North African catfish. These findings suggest the need to focus on developing a DNA barcoding system for classifying clariid catfish properly and to validate its efficacy for a wider range of clariid catfish. With an enriched database of multiple sequences from a target species and its genus, species identification can be more accurate and biodiversity assessment of the species can be facilitated.
