Two new species of fanged frogs from Peninsular Malaysia (Anura: Dicroglossidae)

Matsui M, Belabut DM, Ahmad N

Zootaxa, 2014;3881(1):75-93.
PMID: 25543621 DOI: 10.11646/zootaxa.3881.1.6

Taxonomic status of fanged frogs from the Peninsular Malaysia, previously assigned to Limnonectes kuhlii, is assessed using genetic and morphological approaches. Phylogenetic relationships inferred from sequences of the mitochondrial and nuclear genes revealed that the fanged frogs from the Peninsula form a monophyletic group and are clearly divergent from other species previously, or even now, assigned to L. kuhlii from Mainland Southeast Asia. In both mtDNA and nuDNA phylogeny, the Malay Peninsula clade diverges into two lineages, one from north (Larut Hill, Perak, and Hulu Terengganu, Terengganu) and another from south (Genting Highlands, Pahang, and Gombak, Selangor). These lineages are separated by large genetic distances, comparable with those observed between some other species of L. kuhlii-like frogs. Although the two lineages are very similar morphologically, they are distinguishable in several morphological traits and are considered heterospecific. We therefore describe them as L. utara sp. nov. and L. selatan sp. nov. These new species differ from all other species of kuhlii-like frogs from Mainland Southeast Asia by the surface of tibia, which is densely covered by large warts.

IAPSO-AIRS: A novel improved machine learning-based system for wart disease treatment

Abdar M, Wijayaningrum VN, Hussain S, Alizadehsani R, Plawiak P, Acharya UR, et al.

J Med Syst, 2019 Jun 07;43(7):220.

Wart disease (WD) is a skin illness on the human body which is caused by the human papillomavirus (HPV). This study mainly concentrates on common and plantar warts. There are various treatment methods for this disease, including the popular immunotherapy and cryotherapy methods. Manual evaluation of the WD treatment response is challenging. Furthermore, traditional machine learning methods are not robust enough in WD classification as they cannot deal effectively with small number of attributes. This study proposes a new evolutionary-based computer-aided diagnosis (CAD) system using machine learning to classify the WD treatment response. The main architecture of our CAD system is based on the combination of improved adaptive particle swarm optimization (IAPSO) algorithm and artificial immune recognition system (AIRS). The cross-validation protocol was applied to test our machine learning-based classification system, including five different partition protocols (K2, K3, K4, K5 and K10). Our database consisted of 180 records taken from immunotherapy and cryotherapy databases. The best results were obtained using the K10 protocol that provided the precision, recall, F-measure and accuracy values of 0.8908, 0.8943, 0.8916 and 90%, respectively. Our IAPSO system showed the reliability of 98.68%. It was implemented in Java, while integrated development environment (IDE) was implemented using NetBeans. Our encouraging results suggest that the proposed IAPSO-AIRS system can be employed for the WD management in clinical environment.

Aggressive, multifocal oral verrucous leukoplakia: proliferative verrucous leukoplakia or not?

Ghazali N, Bakri MM, Zain RB

J Oral Pathol Med, 2003 Aug;32(7):383-92.
PMID: 12846784

Some oral verrucal lesions may constitute parts of the clinicopathological spectrum of proliferative verrucous leukoplakia (PVL). Because of its idiopathic yet sinister nature, it is possible that PVL may exist in other populations. The aim of this study was to review the clinicopathological features of persistent, multifocal, oral verrucal lesions in Malaysian population.

Fulltext Exophytic Verrucous Hyperplasia of the Oral Cavity – Application of Standardized Criteria for Diagnosis from a Consensus Report

Zain RB, Kallarakkal TG, Ramanathan A, Kim J, Tilakaratne WM, Takata T, et al.

Asian Pac J Cancer Prev, 2016 01 09;17(9):4491.
PMID: 27865210 DOI: 10.7314/APJCP.2016.17.(9).4491

Verruco-papillary lesions (VPLs) of the oral cavity described in the literature involve a spectrum of conditions
including squamous papilloma, verruca vulgaris, focal epithelial hyperplasia, condyloma, proliferative verrucous
leukoplakia and verrucous carcinoma. A majority of the VPLs are slow growing, benign in nature and have a
viral aetiology. Virus associated benign mucosal outgrowths are not too difficult to diagnose either clinically or
by microscopy. Apart from virus-associated lesions, VPLs harboring malignant potential or behaviour such as
verrucous carcinoma, proliferative verrucous leukoplakia, oral verrucous hyperplasia (OVH), oral papillary
squamous cell carcinoma (PSCC) and oral conventional squamous cell carcinoma with papillary features (CSCC)
need to be further clarified for better understanding of their predictable biologic behavior and appropriate
treatment. Current understanding of potentially malignant VPLs is perplexing and is primarily attributed to
the use of confusing and unsatisfactory terminology. In particular, the condition referred to as oral verrucous
hyperplasia (OVH) poses a major diagnostic challenge. OVH represents a histopathological entity whose clinical
features are not well recognised and is usually clinically indistinguishable from a verrucous carcinoma and a
PSCC or a CSCC. A consensus report published by an expert working group from South Asia as an outcome of
the ‘First Asian Regional Meeting on the Terminology and Criteria for Verruco-papillary Lesions of the Oral
Cavity’ held in Kuala Lumpur, Malaysia, recognised the clinical description of these OVH as a new entity named
‘Exophytic Verrucous Hyperplasia’. Previously described clinical features of OVH such as the ‘blunt’ or ‘sharp’
variants; and the ‘mass’ or ‘plaque’ variants can now collectively fall under this newly described entity. This paper
discusses in detail the application of the standardized criteria guidelines of ‘Exophytic Verrucous Hyperplasia’
as published by the expert group which will enable clinicians and pathologists to uniformly interpret their pool
of OVH cases and facilitate a better understanding of OVH malignant potential.

Chronic wounds and scar tissues are prone to skin cancer. In 1828, Jean-Nicholas Marjolin described the occurrence of tumours in post-traumatic scar tissue. He did not, however, identify the warty ulcers he described as malignant. It was Dupuytren, who about two years later, noted that these lesions were cancerous. The eponym was bestowed by Da Costa in 1903. Marjolin's ulcer no longer refers only to carcinomas secondary to burns and is classified as a malignancy that arises from previously traumatised, chronically inflamed, or scarred skin. It has been reported in relation to osteomyelitis, venous stasis ulcer, tropical ulcers, chronic decubitus ulcer, frostbite, pilonidal sinus, vaccination site, urinary fistula, hidradenitis suppurativa, skin graft donor site, gunshot wounds, puncture wounds, dog bites, and lupus rash. Early arising Marjolin's ulcer has rarely been described in literature. In this case report, we present the CT appearances of Marjolin's ulcer in the left gluteal region of a young man.

Tinospora crispa Miers (Menispermaceae) is a climbing vine with stems rich in warts. The plant is called Akar Seruntum or Patawali in Malaysia and is widely used for treating skin complaints, malaria, bacterial abscess, high blood pressure and diabetes. In the present study, the stems of T. crispa were collected from the locality and succesively extracted with petroleum ether, followed by chloroform and ethanol. The insecticidal active extract (ethanol extract) was subjected to column chromatography of silica gel eluted with a gradient mobile phase containing hexane, chloroform and ethanol. Among the chemical constituents isolated are n-tetracosyl trans-ferulate and n-octacosyl alcohol, along with three known aporphine alkaloids; N-formylnornuciferine, N-acetylnornuciferine and lysicamine. All compounds were identified by comparing their spectroscopic data (UV, IR, 1H NMR, MS) with data from corresponding values in the literature. Isolation of n-tetracosyl trans-ferulate and noctacosyl alcohol is reported the first time for T. crispa.

Fulltext Staged resection in the management of HIV-related anogenital giant condyloma acuminatum. A case report

Loo GH, Lim LY, Zainuddin ZM, Fam XI

Ann Med Surg (Lond), 2019 Dec;48:73-76.
PMID: 31737262 DOI: 10.1016/j.amsu.2019.10.024

Introduction: Giant condyloma acuminata (GCA), also known as Bushke-Lowenstein tumour, is a rare disease which affects 0.1% of the population. Although histopathologically benign, it tends to be locally destructive. The common sites of involvement include the penis and the anorectum. Due to the rarity of the disease, there is a lack of controlled studies on the optimal management of this entity. Thus, we report a case of anogenital GCA in a 40-year-old HIV-positive man.
Case presentation: A 40-year-old man presented with progressive anogenital warts associated with foul-smelling discharge and fever. He has been diagnosed with HIV and was on HAART on presentation. A warty excrescence had infiltrated the entire external genitalia, gluteals and sacral region. Serial excision was performed along with a defunctioning colostomy. The patient recovered well, and the final histopathological showed features of GCA.
Discussion: With HIV, the HPV infection goes unchecked may develop into GCA. Malignant transformation to squamous cell carcinoma may occur in more than half of the cases. A complex interaction between HIV and HPV may lead to a higher risk of recurrence even after resection. The diagnosis is usually clinical. Imaging modalities may be used in identifying the extent and depth of invasion.
Conclusion: The optimal management of anogenital giant condyloma acuminata remains to be determined. Staged surgical excision should be conducted to achieve an optimum outcome. Radical reconstructive surgery should be reserved for patients with recurrence, malignant transformation or sphincter involvement.

PMID: 32281589

INTRODUCTION: Chlamydia trachomatis is one of the most common sexually transmitted diseases (STDs) globally. However, data on its prevalence and risk factors in Malaysia is still scarce.
OBJECTIVE: We aimed to identify the prevalence and risk factors of genitourinary C.trachomatis infection among patients attending STD clinics in northern Peninsular Malaysia.
METHODS: A hospital-based cross-sectional study was conducted in STD clinics of Hospital Pulau Pinang and Hospital Sultanah Bahiyah, Kedah from January to November 2014. Participants were individually interviewed using a structured data collection form followed by a physical examination and laboratory tests. Nucleic Acid Amplification Test (NAAT) was used to detect C.trachomatis infection. Analysis was carried out using SPSS Version 15.
RESULTS: Eighty-three sexually active patients were enrolled, consisting of 51 males and 32 females. The median age was 28.0 years. In general, 32.5% patients were asymptomatic, the remaining presented with genital discharge (41.0%), genital warty lesion (25.3%), genital ulcer (13.3%), dysuria (13.3%), dyspareunia (2.4%), urine hesistancy (1.2%) and genital swelling (1.2%). The prevalence of genitourinary C.trachomatis infection was 21.7% in the study population; 17.6% in males and 28.1% in females. Among the infected females, 44.4% were pregnant. Of those infected 56.6% did not show any symptoms of genital infection, and 77.8% were aged between 18 and 30 years, of which most were females. Among newly diagnosed HIV patients, the prevalence was 14.3%. From multivariable logistic regression analysis, age under 28 years, being married and engagement in oral sex had significantly increased odds of C.trachomatis infection.
CONCLUSIONS: C.trachomatis infection was common among patients attending STD clinics in northern Penisular Malaysia especially in the younger age groups. Majority of the infected patients were asymptomatic.
