Thalassaemia is an inherited blood disorder and is a significant public health alarm in Malaysia
with many not knowing they are carriers of this haemoglobin disorders. Materials and methods: This study
conducted a one off collection of blood samples from 72 Malays students of International Islamic University
Malaysia (IIUM) in Kuantan. Blood samples were subjected to conventional haemoglobin analyses that include
full blood count and picture, HPLC, Haemoglobin electrophoresis and H-inclusion test. All samples were also
genotyped for alpha thalassaemia–1 of Southeast Asia (a-Thal1SEA). Result: There were 17(23.6%) students
who were diagnosed as thalassaemia carriers. Out of this, four (5.5 %) and six (8.3 %) students were presumptive
β-thalassaemia trait and Haemoglobin-E trait as determined by the HPLC assay respectively. Nine
(12.5%) students were genotyped a-Thal1SEA among whom two were also β-thalassaemia carriers. All thalassaemia
cases had MCH of < 27pg. Nonetheless, two out of six Haemoglobin-E trait and three out of nine
a-Thal1SEA carrier had MCV value of >80fL. Two out of four (50%) presumptive β -thalassaemia trait and one
out of six (17%) students of presumptive Haemoglobin-E trait had family history of thalassaemia respectively.
Conclusion: The high occurrence of the three common types of thalassaemia carrier (β, Hb-E and a-Thal1SEA
thalassaemia) in our small group of subjects could be due to better participation of students who had family
history of thalassaemia. The study reaffirmed the importance of molecular study for detection of alpha-thalassaemia
and the use of MCH value of <27pg rather than MCV value of < 80fL for prediction of thalassaemia.

Background: Synovial sarcoma (SS) is a rare cancer and accounts for 5-10% of adult soft tissue
sarcomas. Making an accurate diagnosis is difficult due to the overlapping histological features of SS
with other types of sarcomas and the non-specific immunohistochemistry profile findings. Molecular
testing is thus considered necessary to confirm the diagnosis since more than 90% of SS cases carry
the transcript of t(X;18)(p11.2;q11.2). The purpose of this study is to diagnose SS at molecular level
by testing for t(X;18) fusion-transcript expression through One-step reverse transcriptase real-time
Polymerase Chain Reaction (PCR). Method: Formalin-fixed paraffin-embedded tissue blocks of 23
cases of soft tissue sarcomas, which included 5 and 8 cases reported as SS as the primary diagnosis
and differential diagnosis respectively, were retrieved from the Department of Pathology, Tengku
Ampuan Afzan Hospital, Kuantan, Pahang. RNA was purified from the tissue block sections and
then subjected to One-step reverse transcriptase real-time PCR using sequence specific hydrolysis
probes for simultaneous detection of either SYT-SSX1 or SYT-SSX2 fusion transcript. Results:
Of the 23 cases, 4 cases were found to be positive for SYT-SSX fusion transcript in which 2 were
diagnosed as SS whereas in the 2 other cases, SS was the differential diagnosis. Three cases were
excluded due to failure of both amplification assays SYT-SSX and control β-2-microglobulin. The
remaining 16 cases were negative for the fusion transcript. Conclusion: This study has shown that
the application of One-Step reverse transcriptase real time PCR for the detection SYT-SSX transcript
is feasible as an aid in confirming the diagnosis of synovial sarcoma.

Marked improvement in the management of thalassaemia
has not been matched by progress in psychosocial
rehabilitation as thalassaemia continues to pose challenges
to patients and their family members. Few studies have been
carried out in Malaysia to look at such issues. This study is therefore to explore the concerns, beliefs and feelings about thalassaemia. It was conducted in the year 2009 over 7 months on “focus groups”, in patients aged 8-22 years and
parents attending Paediatric Clinic of Tengku Ampuan Afzan
Hospital, Kuantan, Pahang. Results showed that concerns
and adverse impact were related to lower grades in
education, poor self-image, less chance of employment,
marriage, financial burden and social integration.
Compliance to subcutaneous iron chelator was poor. There
were various concerns related to blood transfusion therapy.
It is evident that thalassaemia greatly affects the
psychosocial dimensions and a more structured long term
psychosocial support is needed to improve quality of life of patients.

Purpose:
Colonoscopy is considered the most reliable method for the diagnosis of juvenile polyps. However, colonoscopic screening is an invasive and expensive procedure. Fecal calprotectin (FCP), a marker of intestinal inflammation, has been shown to be elevated in patients with polyps. Therefore, this study aimed to evaluate FCP as a screening biomarker for the diagnosis of juvenile polyps.
Methods:
This cross-sectional, observational study was conducted at the Pediatric Gastroenterology and Nutrition Department, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. For children with polyps, colonoscopic polypectomy and histopathology were performed. FCP levels were analyzed before and 4 weeks after polypectomy in all patients. Information was recorded in a datasheet and analyzed using the computer-based program SPSS.
Results:
The age of the children was between 2.5 and 12 years. Approximately 93% of the polyps were found in the rectosigmoid region. Children with juvenile polyps had elevated levels of FCP before polypectomy that subsequently normalized after polypectomy. The mean FCP levels before and after polypectomy were 277±247 µg/g (range, 80–1,000 µg/g) and 48.57±38.23 µg/g (range, 29–140 µg/g) (p<0.001), respectively. The FCP levels were significantly higher in patients with multiple polyps than in those with single polyps. Moreover, mean FCP levels in patients with single and multiple polyps were 207.6±172.4 µg/ g and 515.4±320.5 µg/g (p<0.001), respectively.
Conclusion
Colonic juvenile polyps were found to be associated with elevated levels of FCP that normalized after polypectomy. Therefore, FCP may be recommended as a noninvasive screening biomarker for diagnosis of colonic juvenile polyps.
