A review of the status of foot and mouth disease in South-East Asia and approaches to control and eradication

Gleeson LJ

Rev. - Off. Int. Epizoot., 2002 Dec;21(3):465-75.
PMID: 12530354

The author presents reports of foot and mouth disease (FMD) submitted between 1996 and 2001 to the Office International des Epizooties (OIE: World organisation for animal health) Sub-Commission for FMD in South-East Asia. Of the ten countries in South-East Asia, FMD is endemic in seven (Cambodia, Laos, Malaysia, Myanmar, the Philippines, Thailand and Vietnam) and three are free of the disease (Brunei, Indonesia and Singapore). Part of the Philippines is also recognised internationally as being free of FMD. From 1996 to 2001, serotype O viruses caused outbreaks in all seven of the endemically infected countries. On the mainland, three different type O lineages have been recorded, namely: the South-East Asian (SEA) topotype, the pig-adapted or Cathay topotype and the pan-Asian topotype. Prior to 1999, one group of SEA topotype viruses occurred in the eastern part of the region and another group in the western part. However, in 1999, the pan-Asian lineage was introduced to the region and has become widespread. The Cathay topotype was reported from Vietnam in 1997 and is the only FMD virus currently endemic in the Philippines. Type Asia 1 has never been reported from the Philippines but was reported from all countries on the mainland except Vietnam between 1996 and 2001. Type A virus has not been reported from east of the Mekong River in the past six years and seems to be mainly confined to Thailand with occasional spillover into Malaysia. The distribution and movement of FMD viruses in the region is a reflection of the trade-driven movement of livestock. There is great disparity across the region in the strength and resources of the animal health services and this has a direct impact on FMD control. Regulatory environments are not well developed and enforcement of regulations can be ineffectual. The management of animal movement is quite variable across the region and much market-driven transboundary movement of livestock is unregulated. Formal quarantine approaches are generally not supported by traders or are not available. Vaccination is not used widely as a control tool because of the expense. However, it is applied by the Veterinary Services in Malaysia to control incursions of the disease and there is a mass vaccination programme for large ruminants in Thailand where the Government produces and distributes vaccine. Vaccination is also used by the commercial pig sector, particularly in the Philippines and Thailand.

Risk factor analysis on the healing time and infection rate of diabetic foot ulcers in a referral wound care clinic

Kee KK, Nair HKR, Yuen NP

J Wound Care, 2019 Jan 01;28(Sup1):S4-S13.
PMID: 30724120 DOI: 10.12968/jowc.2019.28.Sup1.S4

OBJECTIVE:: Objectives. To determine the prevalence and risk factors for diabetic foot infection (DFI), and to identify factors associated with delayed wound healing of diabetic foot ulcer (DFU).
METHOD:: The retrospective study was performed in a referral wound care clinic in Hospital Kuala Lumpur. Data was collected from January 2014 to October 2016 on DFU patients who attended this clinic.
RESULTS:: Of the 340 patients (216 male and 124 female) DFU patients who attended the clinic (mean age: 58.1±10.8 years old), 41.5% presented with infection with a mean cross-sectional ulcer area of 21.5±33.2cm2. Binary logistic regression analysis revealed that patients of Chinese ethnicity (OR: 3.39; 95%CI 1.49 to 7.70), with fasting blood glucose ≥7mmol/l (OR: 3.41; 95%CI 1.57 to 7.39), ulcer size ≥10cm2 (OR: 2.90; 95%CI 1.45 to 5.82) and blood pressure ≥140/90mmHg (OR: 2.52; 95%CI 1.54 to 4.14) were more likely to develop DFI. The median healing time for patients with DFUs was three months. There were six variables identified as significantly associated with prolonged healing time of DFU, namely presence of infection (p<0.001), poor glycaemic control with fasting blood glucose ≥7mmol/l (p<0.001), high blood pressure ≥140/90mmHg (p<0.001), large DFU size ≥2cm2 (p<0.001), history of amputation (p<0.005) and plantar location of the DFU (p<0.05).
CONCLUSION:: Large DFU size, poor glycaemic and blood pressure control are common risk factors for both DFU and DFI. Unexpected high prevalence and ethnicity risk factor for DFI urge more comprehensive primary and secondary preventative strategies to reduce its incidence.

Area of hock hair loss in dairy cows: risk factors and correlation with a categorical scale

Lim PY, Huxley JN, Green MJ, Othman AR, Potterton SL, Brignell CJ, et al.

Vet J, 2015 Feb;203(2):205-10.
PMID: 25577022 DOI: 10.1016/j.tvjl.2014.11.005

Data from 3691 dairy cows from 76 farms were used to investigate the risk factors associated with the area of hair loss over the lateral aspect of the hock and the correlation between the area of hair loss (as calculated using a hock map) and hock lesion scores determined using a pre-existing categorical scale. Six factors were associated with a greater area of hair loss, including cows with locomotion score 3, a cleanliness score (10/28 to 18/28), high daily milk yield (25.1-58.1 kg), poor body condition score (1-1.5), duration of winter housing (≥41 days) and some combinations of cubicle base and bedding materials. Compared with cows housed in cubicles with a concrete base and whole straw or rape straw bedding, cows housed in cubicles with concrete bases with sand or chopped straw bedding had smaller areas of hair loss and cows housed on a mattress base with whole straw or rape straw bedding had larger areas of hair loss. Area of hair loss, as measured on hock maps, was not significantly different between cows with score 1 (median 23.6 cm(2)) and score 2 (median 20.3 cm(2)) on the categorical scale for hock lesions. This suggests that the categorical scale was not reflecting the extent of hair loss and that hock maps are a good alternative for studying the dynamics of hock lesions over time.

Outbreaks of foot-and-mouth disease in Peninsular Malaysia from 2001 to 2007

Ramanoon SZ, Robertson ID, Edwards J, Hassan L, Isa KM

Trop Anim Health Prod, 2013 Feb;45(2):373-7.
PMID: 22826115 DOI: 10.1007/s11250-012-0226-x

This is a retrospective study of the outbreaks of foot-and-mouth disease (FMD) in Peninsular Malaysia between 2001 and May 2007. In total, 270 outbreaks of FMD were recorded. Serotype O virus (89.95 %) and serotype A (7.7 %) had caused the outbreaks. Significant differences on the occurrence of FMD were found between the years (t = 5.73, P = 0.000, df = 11), months (t = 4.7, P = 0.000, df = 11), monsoon season (t = 2.63, P = 0.025, df = 10) and states (t = 4.84, P = 0.001, df = 10). A peak of outbreaks observed in 2003 could be due to increased animal movement and the other peak in 2006 could be due to a compromised FMD control activities due to activities on the eradication of highly pathogenic avian influenza. Cattle (86 % of outbreaks) suffered the most. However, no difference in disease occurrence between species was observed. The populations of cattle (r = 0.672, P = 0.023) and sheep (r = 0.678, P = 0.022) were significantly correlated with occurrence of FMD. Movement of animals (66 % of outbreaks) was the main source for outbreaks. A combination of control measures were implemented during outbreaks. In conclusion, the findings of this study show that FMD is endemic in Peninsular Malaysia, and information gained could be used to improve the existing control strategy.

Sham NM, Krishnarajah I, Ibrahim NA, Lye MS

Geospat Health, 2014 May;8(2):503-7.
PMID: 24893027

Hand, foot and mouth disease (HFMD) is endemic in Sarawak, Malaysia. In this study, a geographical information system (GIS) was used to investigate the relationship between the reported HFMD cases and the spatial patterns in 11 districts of Sarawak from 2006 to 2012. Within this 7-years period, the highest number of reported HFMD cases occurred in 2006, followed by 2012, 2008, 2009, 2007, 2010 and 2011, in descending order. However, while there was no significant distribution pattern or clustering in the first part of the study period (2006 to 2011) based on Moran's I statistic, spatial autocorrelation (P = 0.068) was observed in 2012.

Fulltext Charcot neuroarthropathy of the foot and ankle

Madan SS, Pai DR

Orthop Surg, 2013 May;5(2):86-93.
PMID: 23658042 DOI: 10.1111/os.12032

Charcot neuroarthropathy (CN) is a rare, progressive, deforming disease of bone and joints, especially affecting the foot and ankle and leading to considerable morbidity. It can also affect other joints such as the wrist, knee, spine and shoulder. This disease, described originally in reference to syphilis, is now one of the most common associates of diabetes mellitus. As the number of diabetics increase, the incidence of CN is bound to rise. Faster initial diagnosis and prompt institution of treatment may help to reduce its sequelae. There should be a low threshold for ordering investigations to assist coming to this diagnosis. No single investigation is the gold standard. Recent studies on pathogenesis and development of newer investigation modalities have helped to clarify the mystery of its pathogenesis and of its diagnosis in the acute phase. Various complementary investigations together allow the correct diagnosis to be made. Osteomyelitis continues to be confused with acute CN. Hybrid positron emission tomography has shown some promise in differentiating these conditions. A multispecialty approach involving diabetologists, orthopaedists and podiatrists should be used to tackle this difficult problem. The aim of this article is to describe current knowledge about CN with particular reference to the status of diagnostic indicators and management options.

Fulltext Low dose unilateral spinal anaesthesia for lower limb amputation in critically ill patients

Chuah KH, Thong CL, Krshnan H, Chan L

Med J Malaysia, 2007 Mar;62(1):81-2.
PMID: 17682582 MyJurnal

Patients with poorly controlled diabetes mellitus have an increased risk of lower limb infection and gangrene. In Malaysia, they frequently present late and are often in septic shock with multi-organ dysfunction. We report on two patients who presented for lower limb amputation in a desperate attempt to control sepsis and save their lives. Both patients were classified as ASA 5. Both patients had successfully undergone surgery under low dose unilateral spinal anaesthesia. The anaesthetic management of these critically ill patients in view of limited resources is discussed.

Evaluation of postural steadiness in below-knee amputees when wearing different prosthetic feet during various sensory conditions using the Biodex® Stability System

Arifin N, Abu Osman NA, Ali S, Gholizadeh H, Wan Abas WA

Proc Inst Mech Eng H, 2015 Jul;229(7):491-8.
PMID: 26019139 DOI: 10.1177/0954411915587595

In recent years, computerized posturography has become an essential tool in quantitative assessment of postural steadiness in the clinical settings. The purpose of this study was to explore the ability of the Biodex(®) Stability System (BSS) to quantify postural steadiness in below-knee amputees. A convenience sample of 10 below-knee amputees participated in the study. The overall (OSI), anterior-posterior (APSI) and medial-lateral (MLSI) stability indexes as well as the percentage of time spent in left and right quadrants and four concentric zones were measured under altered sensory conditions while standing with solid ankle cushion heel (SACH), single-axis (SA) and energy storage and release (ESAR) feet. Significant difference was found between sensory conditions in SACH and ESAR feet for OSI (SACH, p = 0.002; ESAR, p = 0.005), APSI (SACH, p = 0.036; ESAR, p = 0.003) and MLSI (SACH, p = 0.008; ESAR, p = 0.05) stability indexes. The percentage of time spent in Zone A (0°-5°) was significantly greater than the other three concentric zones (p < 0.01). The loading time percentage on their intact limb (80%-94%) was significantly longer than the amputated limb (20%-6%) in all conditions for all three prosthetic feet. Below-knee amputees showed compromised postural steadiness when visual, proprioceptive or vestibular sensory input was altered. The findings highlight that the characteristics of postural stability in amputees can be clinically assessed by utilizing the outcomes produced by the BSS.

Fulltext Improvement of diabetic wound healing by topical application of Vicenin-2 hydrocolloid film on Sprague Dawley rats

Tan WS, Arulselvan P, Ng SF, Mat Taib CN, Sarian MN, Fakurazi S

BMC Complement Altern Med, 2019 Jan 17;19(1):20.
PMID: 30654793 DOI: 10.1186/s12906-018-2427-y

BACKGROUND: Impaired wound healing is a debilitating complication of diabetes that leads to significant morbidity, particularly foot ulcers. The risk of developing diabetic foot ulcers for diabetic patients is 15% over their lifetime and approximately 85% of limb amputations is caused by non-healing ulcers. Unhealed, gangrenous wounds destroy the structural integrity of the skin, which acts as a protective barrier that prevents the invasion of external noxious agents into the body. Vicenin-2 (VCN-2) has been reported to contain prospective anti-oxidant and anti-inflammatory properties that enhance cell proliferation and migration. Sodium Alginate (SA) is a natural polysaccharide that possesses gel forming properties and has biodegradable and biocompatible characteristics. Therefore, the objective of this study is to evaluate the effect of SA wound dressings containing VCN-2 on diabetic wounds.
METHODS: Wounds were inflicted in type-1 diabetic-streptozotocin (STZ) induced male Sprague Dawley rats. Subsequently, relevant groups were topically treated with the indicated concentrations (12.5, 25 and 50 μM) of VCN-2 hydrocolloid film over the study duration (14 days). The control group was treated with vehicle dressing (blank or allantoin). Wounded tissues and blood serum were collected on 0, 7 and 14 days prior to sacrifice. Appropriate wound assessments such as histological tests, nitric oxide assays, enzyme-linked immunosorbent assays (ELISA) and immunoblotting assays were conducted to confirm wound healing efficacy in the in vivo model. One-way Analysis of Variance (ANOVA) was used for statistical analysis.
RESULTS: Results showed that hydrocolloid film was recapitulated with VCN-2 enhanced diabetic wound healing in a dose-dependent manner. VCN-2 reduced pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α), mediators (iNOS and COX-2), and nitric oxide (NO) via the NF-κB pathway. Data suggests that the VCN-2 film facilitated healing in hyperglycemic conditions by releasing growth factors such as (VEGF and TGF-β) to enhance cell proliferation, migration, and wound contraction via the VEGF and TGF-β mechanism pathways.
CONCLUSIONS: This study's findings suggest that VCN-2 may possess wound healing potential since topical treatment with VCN-2 hydrocolloid films effectively enhanced wound healing in hyperglycemic conditions.

Clin Orthop Relat Res, 2001 Feb.
PMID: 11210956

A system for assessing the results of tibialis posterior tendon transfers in the treatment of foot drop secondary to nerve palsy is proposed. There are seven sections to this scoring system: pain, need for orthosis, ability to wear normal shoes, activity level, muscle power of ankle dorsiflexion, degree of active ankle dorsiflexion, and foot posture. The total score is 100. The results are classified as excellent for scores between 85 and 100, good between 70 and 84, fair between 55 and 69, and poor for scores below 55. The results of 18 patients (mean followup, 64.6 months) who had a tibialis posterior tendon transfer were assessed using this method. Four patients (22.2%) had an excellent result, seven (38.8%) had a good result, two (11.1%) had a fair result, and five (27.7%) had a poor result. The average score was 67.2, suggesting an overall fair result for this operation. In nine patients, there was correlation between the outcome when assessed with this method and with patient rating. In two patients, the outcomes were better when assessed with this method than with patient rating, whereas the reverse was true in seven other patients. Thus, this system may provide a more objective and critical evaluation of tibialis posterior transfers for foot drop.

MyJurnal

Diabetic foot disease is the leading cause of non-traumatic amputations of the lower limb, hence a major health care and socioeconomic burden. It has been found that most of the costs occur in the inpatient setting; therefore this study is to quantify the costs of managing inpatient diabetic foot infections (DFI). We treated 182 inpatients from May 2012 till April 2013 and analysed the cost of antibiotic usage, wound dressing, surgical procedure, admission and basic investigation costs. The total cost was ~ USD 11,000 (2013). This number, however, only reflects the cost for managing an acute infection. The price for follow-up care as an outpatient, rehabilitation and indirect costs (emotional suffering, reduced productivity) is estimated to be much more.

Nair HKR

J Wound Care, 2018 Sep 01;27(Sup9a):S32-S36.
PMID: 30207850 DOI: 10.12968/jowc.2018.27.Sup9a.S32

OBJECTIVE: To study the effectiveness of nano-colloidal silver and chitosan bioactive wound dressings in the treatment of diabetic foot ulcers (DFU).
METHOD: Patients with DFUs were selected randomly. Wound size, appearance and presence of infection were recorded at each dressing change.
RESULTS: We assessed five patients in this case series. The use of both nano-colloidal silver and chitosan biopolymer dressings aided wound healing. The patients did not require surgical debridement or amputation. All five cases in this study had a slow healing rate at presentation.
CONCLUSION: Applications of nano-colloidal silver in conjunction with chitosan bioactive as primary dressings in managing DFUs cases are safe and help increase wound healing rates, thus, leading to significant cost savings in the hospital setting.

Fulltext Bilateral Talus and Navicular Fractures accompanied with Unilateral Calcaneal Fracture: A Case Report

Bulut G, Colak I, Mik G, Kilic Z, Tasdemir Z

Malays Orthop J, 2018 Jul;12(2):47-51.
PMID: 30112129 DOI: 10.5704/MOJ.1807.009

An 18-year old male patient, with a history of paragliding accident, sustaining a coronal shear fracture of the body of the talus, an anterior process fracture of the calcaneus extending to the calcaneocuboid joint and a nondisplaced navicular body fracture at the right foot and a displaced fracture of the navicular body accompanied with posteromedial process fracture of the talus at the left side was referred to our emergency clinic. For the right foot, the coronal plane fracture of the talar body was anatomically reduced and fixed with screws. For the left foot, screw fixation was performed through the lateral aspect to fix the large posteromedial fragment. Small bone fragments were removed from the left navicular fracture, and the main fragments were also fixed with screw. The talo-navicular joint was stabilised with a Kirschner wire. At 36 months follow-up, bilateral foot and ankle functions were satisfactory, Maryland scores of the right and left foot were 85 (good) and 90 (excellent), respectively, and the patient regained his full activity level by the 5th month postoperatively. With reference to the number and types of fractures in this one patient, we present a standard protocol for treatment of isolated talus, navicular and calcaneal fractures presenting together in a single foot injury.
