Ramzisham ARM, Azizi AB, Zurin AAR

Med J Malaysia, 2004 Oct;59(4):530-2.

PMID: 15779587

A 62-year-old man presented with a 2-month history of right occipito-parietal headache and worsening ipsilateral ptosis. CT scan and cerebral angiography revealed a large fusiform aneurysm of the P2 segment of the right posterior cerebral artery (PCA). The aneurysm was successfully trapped and subsequently excised via sub temporal approach leaving no additional neurological deficits to our patient.

Fulltext Sliding compression screw fixation for delayed union/non-union of femoral neck fracture: is it a viable option

Faisham WI, Sulaiman AR, Zulmni W

Med J Malaysia, 2006 Feb;61 Suppl A:36-9.

PMID: 17042227

Femoral neck fracture non-unions often present with significant difficult treatment decision as regards to surgical options and the risk of complication. We present three cases of femoral neck non-union treated with double screw stabilization technique using sliding compression hip screw and anti-rotational screw. The rationale for opting to these simple implants in our setting is discussed.

Fulltext Versatility of the latissimus dorsi flap in upper limb salvage tumour surgery

Dorai AA, Halim AS, Zulmi W

Med J Malaysia, 2004 Dec;59 Suppl F:42-6.

PMID: 15941160

Reconstructive surgeons often encounter complex soft tissue and skeletal defects following oncological surgery. Soft tissue defects after wide resection in upper extremities posses a difficult challenge to find adequate tissue for reconstructing these defects. Paucity of local tissues dictates the requirement of loco-regional or distant flaps for these complex soft tissue defects which often exposes tendons, bones, nerves and joints. The latissimus dorsi muscle is a near ideal flap for the reconstruction because of the long neurovascular pedicle, ease of mobilization and its expendability. It can be rotated, with or without overlying skin, to cover soft tissue defects of the shoulder arm and elbow. Due to the large size of the muscle, it can be used to resurface the soft tissue defects and cover all major structures. Eleven consecutive cases were reviewed in which latissimus dorsi myocutaneous flap was used to reconstruct soft tissue defects of the upper limb following radical tumor resection. Flap survival was 100% with nominal donor site morbidity.

Fulltext Assessment of Extra-Cortical Bone Bridge Interface in Cemented Mega Endoprosthesis for Limb Salvage Surgery

Murugan K, Faisham WI, Zulmi W

Malays Orthop J, 2021 Mar;15(1):93-99.

PMID: 33880154 DOI: 10.5704/MOJ.2103.014

Introduction: Mega endoprosthesis replacement for resection of primary malignant bone tumour requires immediate and long-term stability, particularly in the young and active patient. Extracortical bone bridge interface (EBBI) is a technique whereby autograft is wrapped around the interface junction of bone and porous-coated implant to induce and enhance bone formation for biological incorporation. This procedure increases the mean torsional stiffness and the mean maximum torque, which eventually improves the implant's long-term survival.

Material and methods: The extracortical bone bridge interface's radiological parameter was evaluated at the prosthesis bone junction two years after surgery utilising a picture archiving and communication system (PACS). The radiograph's anteroposterior and lateral view was analysed for both thickness and length in all four cortices. The analysis was done in SPSS Version 24 using One-Way ANOVA and independent T-Test. Results were presented as mean and standard deviation and considered significant when the p-value was < 0.05.

Results: The mean average thickness was 2.2293mm (SD 1.829), and the mean average length was 31.95% (SD 24.55). We observed that the thickness and length of EBBI were superior in the young patient or patients with giant cell tumour that did not receive chemotherapy, compared to patients treated for osteosarcoma. The distal femur also had better EBBI compared to the proximal tibia. However, the final multivariable statistical analysis showed no significant difference in all variables. EBBI thickness was significantly and positively correlated with EBBI Length (p<0.001). We conclude that, for each 1mm increase in EBBI thickness, the length will increase by 0.06% on average. About 17.2% of patients out of the 29 showed no radiological evidence of EBBI.

Conclusion: From our study, there were no factors that significantly contributed to the formation and incorporation of EBBI.

Fulltext Spontaneous closure of a persistent post-traumatic pancreatic fistula in a child: incidental therapeutic effect of ERCP

Thambidorai CR, Ismail S, Chan KY, Haron A, Zulfiqar A

Med J Malaysia, 2004 Mar;59(1):120-2.

PMID: 15535349

A child with a post-tramatic pancreatic pseuodocyst developed pancreatic fistula, following percutaneous drainage of the cyst. The fistula output was about 120ml/day and lasted for a month. A diagnostic ERCP revealed main pancreatic duct disruption. The fistula output ceased over the next two days following the ERCP. The patient has been well for the past four years. This patient's immediate recovery after ERCP could possibly be due to dislodgement of a mucus plug by the contrast injected during ERCP. Such a mechanism can explain the previous sporadic reports of spontaneous cure of persistent pancreatic fistulae in children.

Encapsulation of Ethylene Gas into Granular Cold-Water-Soluble Starch: Structure and Release Kinetics

Shi L, Fu X, Tan CP, Huang Q, Zhang B

J Agric Food Chem, 2017 Mar 15;65(10):2189-2197.

PMID: 28215072 DOI: 10.1021/acs.jafc.6b05749

Ethylene gas was introduced into granular cold-water-soluble (GCWS) starches using a solid encapsulation method. The morphological and structural properties of the novel inclusion complexes (ICs) were characterized using scanning electron microscopy, X-ray diffractometry, and Raman spectroscopy. The V-type single helix of GCWS starches was formed through controlled gelatinization and ethanol precipitation and was approved to host ethylene gas. The controlled release characteristics of ICs were also investigated at various temperature and relative humidity conditions. Avrami's equation was fitted to understand the release kinetics and showed that the release of ethylene from the ICs was accelerated by increasing temperature or RH and was decelerated by increased degree of amylose polymerization. The IC of Hylon-7 had the highest ethylene concentration (31.8%, w/w) among the five starches, and the IC of normal potato starch showed the best controlled release characteristics. As a renewable and inexpensive material, GCWS starch is a desirable solid encapsulation matrix with potential in agricultural and food applications.

Fulltext Symptomatic chronic strongyloidiasis in children following treatment for solid organ malignancies: case reports and literature review

Norsarwany M, Abdelrahman Z, Rahmah N, Ariffin N, Norsyahida A, Madihah B, et al.

Trop Biomed, 2012 Sep;29(3):479-88.

PMID: 23018511

Strongyloidiasis is an infection caused by the intestinal nematode Strongyloides stercoralis. Infected healthy individuals are usually asymptomatic, however it is potentially fatal in immunocompromised hosts due to its capacity to cause an overwhelming hyperinfection. Strongyloidiasis could be missed during routine screening because of low and intermittent larval output in stool and variable manifestations of the symptoms. We present two cases of strongyloidiasis occurring in children with solid organ malignancies suspected to have the infection based on their clinical conditions and treatment history for cancer. Both patients were diagnosed by molecular and serological tests and were successfully treated. Thus, strongyloidiasis in patients undergoing intensive treatment for malignancies should be suspected, properly investigated and treated accordingly.

Fulltext Large adrenocortical carcinoma extending into the inferior vena cava and right atrium

Hisham AN, Sarojah A, Zanariah H

Asian J Surg, 2003 Jan;26(1):40-2.

PMID: 12527494

A case of large adrenocortical carcinoma extending into the inferior vena cava and right atrium is reported. Computed tomography showed a large mass displacing the left kidney inferiorly with an intravascular tumour thrombus extending into the inferior vena cava and right atrium. Radical surgery under hypothermia and cardiopulmonary bypass was performed and the tumour mass, together with the tumour thrombus, was successfully removed. The presence of intravascular tumour extension alone should not be a contraindication to radical surgical therapy, as it is the best hope for prolonged survival.

MyJurnal

Critical size defects (CSD) in the long bones of New Zealand White rabbits (Oryctolagus cuniculus) have been used for years as an experimental model for investigation of the effectiveness of a new bone substitute material. There are varieties of protocols available in the literature. This technical note attempts to present an alternative surgical technique of a CSD in the New Zealand white rabbit tibia. Methods: Thirty-nine New Zealand White rabbits were used in this study. A CSD of approximately 4.5 mm (width) X 9.0 mm (length) was surgically drilled at the proximal tibial metaphysis, approximately 1 cm from the knee joint. The surrounding of soft tissue was repositioned and sutured layer by layer with bioabsorbable surgical suture. Two x-rays of anteroposterior and lateral were taken before assessed under computed tomography scan at 6, 12 and 24 weeks. Results: This alternative method created CSD with less bleeding from the muscle observed. No mortality or other surgical complications observed within 6 weeks, 12 weeks and 24 weeks following surgery. Conclusion: A simple and safe method for performing CSD was demonstrated and recommended as an alternative approach for surgery on New Zealand White rabbits.

Ramzisham AR, Raflis AR, Khairulasri MG, Ooi Su Min J, Fikri AM, Zamrin MD

Asian Cardiovasc Thorac Ann, 2009 Dec;17(6):587-91.

Sternal dehiscence is a rare but devastating complication following median sternotomy for cardiac surgery. The optimal technique for sternal closure is unclear. We conducted this prospective randomized trial to compare the incidence of sternal dehiscence after figure-of-8 and simple interrupted suturing in patients undergoing coronary artery bypass grafting. Between January 2007 and June 2008, 98 patients had figure-of-8 suturing and 97 had interrupted sutures. The mean age of the patients was 60.9 +/- 7.6 years. The overall sternal dehiscence rate was 8%; 7 cases in the in figure-of-8 group and 9 in the interrupted group. Thirteen patients had no wound infection and healed with conservative treatment. Only 3 patients had sternal dehiscence with infection: 2 with simple interrupted closure and 1 with figure-of-8 sternal closure. There was no significant difference in rates of sternal dehiscence between the 2 groups. It was concluded that figure-of-8 sternal suturing is equally effective as simple interrupted suturing in preventing sternal dehiscence.

Materials (Basel), 2013 May 15;6(5):2059-2073.

PMID: 28809260 DOI: 10.3390/ma6052059

e effects of biological pretreatment on the rubberwood (Hevea brasiliensis), was evaluated after cultivation of white rot fungi Ceriporiopsis subvermispora, Trametes versicolor, and a mixed culture of C. subvermispora and T. versicolor. The analysis of chemical compositions indicated that C. subvermispora had greater selectivity for lignin degradation with the highest lignin and hemicellulose loss at 45.06% and 42.08%, respectively, and lowest cellulose loss (9.50%) after 90 days among the tested samples. X-ray analysis showed that pretreated samples had a higher crystallinity than untreated samples. The sample pretreated by C. subvermispora presented the highest crystallinity of all the samples which might be caused by the selective degradation of amorphous components. Fourier transform infrared (FT-IR) spectroscopy demonstrated that the content of lignin and hemicellulose decreased during the biological pretreatment process. A study on hydrolysis of rubberwood treated with C. subvermispora, T. versicolor, and mixed culture for 90 days resulted in an increased sugar yield of about 27.67%, 16.23%, and 14.20%, respectively, as compared with untreated rubberwood (2.88%). The results obtained demonstrate that rubberwood is a potential raw material for industrial applications and white rot fungus C. subevermispora provides an effective method for improving the enzymatic hydrolysis of rubberwood.

PMID: 10543517

A 10-month-old boy underwent operation to close a large secundum atrial septal defect and multiple muscular ventricular septal defects. Closure of the ventricular septal defects was unsuccessful and led to worsening cardiac failure and inability to wean the patient from mechanical ventilation. Transcatheter closure of the ventricular septal defects using Gianturco coils was undertaken. This technique is an effective alternative for closure of multiple muscular ventricular septal defects in infants and small children.

PMID: 22558017 DOI: 10.4103/1817-1737.94534

This was a case of a 35-year-old man with mediastinal mass requiring computed tomography (CT)-guided biopsy for tissue diagnosis. A posterior approach with an 18-gauge biopsy needle was used to obtain tissue sample. Post biopsy, patient condition deteriorated and multiphase CT study detected active bleeding in arterial phase at the biopsy site with massive hemothorax. Subsequent angiography showed arterial bleeder arising from the apical branch of the right pulmonary artery. Selective endovascular embolization with NBCA (n-Butyl cyanoacrylate) was successful. Patient survived the complication. The case highlighted a rare complication in a common radiology procedure and the value of the interventional radiology unit in avoiding a fatal outcome.

Fulltext Radiation exposure to the surgeon during femoral interlocking nailing under fluoroscopic imaging

Muzaffar TST, Imran Y, Iskandar MA, Zakaria A

Med J Malaysia, 2005 Jul;60 Suppl C:26-9.

PMID: 16381279

Femoral interlocking nailing requires fluoroscopic assistance for insertion of the nail and distal screws. In this study, scattered radiation to the eye and hand of the operating surgeon was measured during the procedure. Thermo-luminescent dosimeter (TLD) was used to quantify the dose received by the surgeon. The mean radiation exposure time during the procedure was 3.89 minutes. The mean scattered radiation doses to the hand and eye were 0.27 mSv and 0.09 mSv per procedure respectively. These very low doses have made a surgeon very unlikely to receive more than the recommended annual dose limit set by the National Council on Radiological Protection.
