The Ministry of Health had instructed all state hospitals to go for Accreditation. Accreditation is considered to be a more appropriate tool forquality assurance in a hospital setting than ISO 9000.The objective of this research was to study doctors perception towards the implementation of Accreditation in state hospital. Self-administered questionnaires were sent through mail to doctors in eight clinical departments of all state hospitals. From 832 questionnaires sent, 297 responded (36%),i.e. 84 specialists and 2/2 medical officers. The study showed that 69% doctors knew that their hospital was implementing Accreditation. There were more clinical specialist (9I%) who were involved in accreditation as compared to Medical Ojicers (73%). 83% of doctors believed that accreditation can assist in assuring quality in their hospital. Those who do not, thought that quality can be assured stajfing was adequate (67%) and accreditation does not assess patient care
(33%). The study also showed that 7I% of doctors knew that their hospital was implementing MS ISO 9000. A 77% of doctors believed that ISO 9000 can assist in assuring quality in their hospital. Those who do not, thought that quality can onhi be assured Jstajfng was adequate (27%) and ISO 9000 was only meant for industry (8%). In conclusion, doctors believed that Accreditation and MS ISO 9000 can assist in assuring quality in their hospitals. Amongst, those who do not, majority thought that quality can only be assured staffing was adequate.
Cross-Linked Enzyme Aggregates (CLEA) is known as one of the best enzyme immobilization technique nowadays. In this study, amylase extract from Zophobas morio (super mealworm) larvae was immobilized using acetone as the precipitant, glutaraldehyde as the cross-linker and bovine serum albumin as the additive. The characteristics of the produced CLEA were compared to the free soluble amylase, in terms of pH and temperature optimum and stabilities. The results displayed that CLEAand free amylase achieved an optimum temperature at 55°C and 45°C, respectively. CLEA-amylase also had showed greater stability against high temperature as compared to a free enzyme which had lost most of its activity when the temperature was set beyond 45°C. In comparison, at 65°C, CLEA-amylase still retained 73.2% of its activity. Results also revealed that CLEA-amylase has a pH optimum at 11, while it is pH 7 for free enzyme. Similarly, CLEA-amylase was more stable than the free form, over a wider range of pH, particularly at higher pH of 9, 10 and 11. Recyclability study showed that CLEA-amylase could retain 14.9% of its residual activity after 6 times of repeated uses. Since it is reusable, future works might include the evaluations of using CLEA-amylase at the industrial level, remarkably in detergent applications.
Many studies have been done on various species of insects to investigate their potential use in industries. This is because insects have high protein content which could be further manipulated. Due to its eating habit, Zophobas morio larvae, also known as super mealworm has been shown to have high amylase activity. In this study, amylase from super mealworm has been immobilized via Cross-Linked Enzyme Aggregates (CLEA) technique and its kinetic performance, evaluated. CLEA is one of the best immobilization method with respect to enzyme stability and reusability. Kinetic performance of both free and CLEA-amylase were evaluated based on the Michaelis-Menten model. Results obtained based on Hanes-Woolf, LineweaverBurk, Eadie-Hofstee and Hyperbolic Regression plots showed that the kinetic parameters, Vmax and KM, changed upon immobilization. For CLEA-amylase, Hanes-Woolf plot showed the bestfitted model based on R2 with Vmax= 1.068 mM/min and KM= 0.182 mM, however, LineweaverBurk plot was used to obtain the kinetic parameters for free amylase, with Vmax and KM of 17.230 mM/min and 2.470 mM, respectively. Thus it is observed that upon immobilization, Vmax for amylase dropped appreciably, however, much lower substrate concentration is needed to saturate the enzymatic sites to reach its maximum catalytic efficiency. The result from this study might open the new path in discovering the potential use of insects in industrial applications, for example, making use of the recovered enzymes in the detergent industry.
Dislocation or subluxation of the hip is considered as the most common hip problem in patients with Down syndrome. Recommended treatment of chronic dislocation treatment is open reduction combined with femoral and/or pelvis osteotomies. We report a Down syndrome child with chronic hip dislocation who was successfully treated with adductor tenotomy and closed reduction, which has not been reported previously.
Post-traumatic chronic osteomyelitis and infected non-unions of the tibia following severe type-III open fracture are difficult to treat Refractoy cases often necessitate amputation despite attempts to salvage the limb. We report our experience in treating such difficult cases with an alternative surgical option using free osteocutaneous fibular graft. Eight consecutive patients with post-traumatic chronic osteomyelitis/infected non-union were treated surgically with free vascularized osteocutaneous fibular graft. Outcomes in term of graft-host union and complication were evaluated. Four patients had anastomotic venous thrombosis requiring anastomotic revision. Five patients developed surgical site infections needing extended antibiotic therapy to achieve resolution at an average of 15.2 weeks. Fibular graft fracture occurred in three patients but all grafts survived and united after a mean time to union of 42.3 weeks (range 31 to 82 weeks). At the final follow-up, union of host-graft junction and control of infection were achieved in all patients except one who required a secondary amputation. Free vascularized osteo-cutaneous fibular graft is a viable limb salvage option for refractory chronic osteomyelitis or infected non-union following treatment of grade-III open tibial fractures.
A rectus abdominis myocutaneous flap can provide a large amount of tissue for defect coverage. Rarely a flabby and redundant abdominal tissue was used as a huge extended flap. We report a case of recurrence malignant fibrous histiocytoma of the thigh which was radically resected. The resultant massive defect was success reconstructed with an extended pedicle inferiorly based rectus abdominis myocutaneous flap.
Eight infants between the ages of one and three months with prolonged conjugated hyperbilirubinaemia had duodenal aspirations performed to differentiate between biliary atresia and neonatal hepatitis. Four infants had bile-stained aspirates and in all of them the jaundice subsided completely by eight months of age. We have found duodenal aspiration a safe, inexpensive and simple procedure to undertake in helping us make a rapid differentiation between patients with conjugated hyperbilirubinaemia requiring urgent laparotomy and those that do not require surgery. This approach appears to be reliable although further studies need to be undertaken.
Management of severe open tibial fracture with neurovascular injury is difficult and controversial. Primary amputation is an acceptable option as salvaging the injured, insensate, and ischaemic limb may result in chronic osteomyelitis and non-functional limb. We report a case of open tibial fracture associated with segmental bone and soft tissue loss, posterior tibial nerve and artery injuries, which was further complicated by chronic osteo-myelitis treated with composite vascularised osteocutaneous fibula and sural nerve graft. Functional outcome of the injured limb at one-year follow-up was satisfactory: the patient was capable of achieving full weightbearing and was able to appreciate crude touch, pain, proprioception, and temperature at the plantar aspect of the foot. There was no pressure sore or ulceration.
The combined latissimus dorsi and serratus anterior flap has been employed for large defect reconstruction and has been shown to be reliable. These flaps are based on the subscapular-thoracodorsal vascular pedicle that usually supplies both muscles. In the case reported, serratus anterior possessed an anomalous arterial supply totally independent of the subscapular pedicle. The latissimus dorsi and serratus anterior muscles were used as a combined flap to reconstruct a massive thigh defect. The combined flap required two arterial anastomoses.
This comparative cross-sectional study assessed the facial surface dimensions of a group of Malay children with unilateral cleft lip and palate (UCLP) and compared them with a control group. 30 Malay children with UCLP aged 8-10 years and 30 unaffected age-matched children were voluntarily recruited from the Orthodontic Specialist Clinic in Hospital Universiti Sains Malaysia (HUSM). For the cleft group, lip and palate were repaired and assessment was performed prior to alveolar bone grafting and orthodontic treatment. The investigation was carried out using 3D digital stereophotogrammetry. 23 variables and two ratios were compared three-dimensionally between both groups. Statistically significant dimensional differences (P<0.05) were found between the UCLP Malay group and the control group mainly in the nasolabial region. These include increased alar base and alar base root width, shorter upper lip length, and increased nose base/mouth width ratio in the UCLP group. There were significant differences between the facial surface morphology of UCLP Malay children and control subjects. Particular surgical procedures performed during primary surgeries may contribute to these differences and negatively affect the surgical outcome.
We report a rare case of septic arthritis in a healthy child caused by Salmonella enteritidis. No predisposing factor was detected. Salmonella enteritidis was isolated from the infected joint tissue obtained following surgical drainage. Based on the culture and sensitivity report, he was treated with a 6-week course of antibiotic. He improved dramatically without any detrimental sequelae at end of one year.
Long bone reconstruction using vascularized fibula graft is becoming more popular despite the difficulties and its post-operative complications. We reviewed our early experience dealing with vascularized fibula graft for the management of massive long bone defect. Thirteen patients had undergone long bone reconstruction using vascularized fibula graft. Early complications that had been encountered include superficial wound infection (23%), transient common peroneal nerve palsy (23%), stage 1 bed sore (7.7%), anastomotic venous thrombosis (30.8%), DIVC (15.4%), flap loss and amputation (7.7%), and reactive psychiatric problem (7.7%). The early complications following this procedure are comparable with other major orthopaedic surgery and most of them are minor and treatable. The complication rates are also comparable with similar surgery done elsewhere.
To our knowledge, meningitis due to Listeria monocytogenes has not previously been reported in Malaysia. We describe here two infants with meningitis due to Listeria monocytogenes occurring within a month of each other in the Universiti Kebangsaan Malaysia Paediatric Unit. The incidence of listeriosis in Malaysia is unknown and it is possible that this infection may have been missed in the past.
Septic arthritis of the hip in children represents a serious disorder with unfavourable long-term sequelae. In neonates, a poor hip outcome is expected especially if the treatment was delayed. Late sequelae can lead to structural joint damage and instability, causing deformity and dislocations which ultimately may result in limb length discrepancy, early degenerative changes and limited range of motion. Surgery at the appropriate time can improve the hip condition and functional outcome. Previous classifications of post septic hip sequelae are useful guides for treatment, but did not discuss one particular group of patient. This group-septic hip dislocation with a preserved femoral head, has recently been described as a distinct entity. This report highlights an 11-year follow-up of a 2-year-old child who had a successful outcome following open reduction and varus derotation
osteotomy for a septic hip dislocation with a preserved femoral head.

Immediate recognition of anastomotic failure is important to ensure the viability of the vascularised fibular graft. The problems associated with post-operative bone scanning and angiography for immediate detection of anastomotic failure have been described.
Thirteen patients had skeletal reconstruction using vascularised fibula graft following resection of the diseased bone. Eleven patients had reconstruction of the lower limbs and two patients of the upper limbs. Clinical and radiographical evidence union were achieved with the average time of 32 weeks (earliest eight weeks). Six out of 11 patients (54%) in lower limb reconstruction started weight bearing at the average of 27 weeks. Bony union in this study is comparable with other studies using vascularised fibula graft.
Extensive full thickness anterior abdominal wall defects pose a difficult challenge to the reconstructive surgeon. The objectives of reconstruction are the support of the intra-abdominal structures in order to preserve the functional integrity and achieve an aesthetically-acceptable appearance. Autologous tissues are versatile and provide the best reconstructive option in this type of defects. The tensor fascia latae myocutaneous flap provides identical abdominal wall musculofascial cover for full thickness defects. In extensive defects, the extended tensor fascia latae flap is a versatile option with a second microvascular anastomosis at the distal end of the flap. A total anterior abdominal wall soft tissue tumour resection defect was reconstructed with the use of the double pedicle extended free tensor fascia latae myocutaneous flap in a 60-year-old man. The patient however succumbed to the disease process six months post-reconstruction. During the follow-up period, there was no evidence of hernia at the anterior abdominal wall.
Honey dressing has been used to promote wound healing for years but scanty scientific studies did not provide enough evidences to justify it benefits in the treatment of diabetic foot ulcers. We conducted a prospective study to compare the effect of honey dressing for Wagner's grade-II diabetic foot ulcers with controlled dressing group (povidone iodine followed by normal saline). Surgical debridement and appropriate antibiotics were prescribed in all patients. There were 30 patients age between 31 to 65-years-old (mean of 52.1 years). The mean healing time in the standard dressing group was 15.4 days (range 9-36 days) compared to 14.4 days (range 7-26 days) in the honey group (p < 0.005). In conclusion, ulcer healing was not significantly different in both study groups. Honey dressing is a safe alternative dressing for Wagner grade-II diabetic foot ulcers.
Sacral tumours often present surgical resection and reconstruction challenges. Wide resections result in large sacral defects and neoadjuvant radiotherapy impairs wound healing. The wounds need to be covered with bulky, well-vascularised, healthy tissues. We present 2 cases where large sacral defects were reconstructed following tumour resection. Both defects were reconstructed with inferiorly based, transpelvic, pedicled vertical rectus abdominis myocutaneous flaps. This is a robust flap and carries a well-vascularised muscle bulk and skin paddle. The donor site is distant from the lesion site and is thus unaffected by both the resection and radiotherapy. This is a useful flap for reconstructing large sacral defects.
Vaginal defects can either be congenital or acquired due to tumor or trauma. The reconstructions are aimed in producing a good physical and functional result with the least donor site morbidity. The pudendal thigh flap is a sensate fasciocutaneous flap based on the terminal branch of the superficial perineal artery, the continuation of the internal pudendal artery. Although various flaps have been described for vaginal reconstruction, the pudendal thigh flap offers a very attractive alternative.
