Allele-specific PCR for a cost-effective & time-efficient diagnostic screening of spinal muscular atrophy

Marini M, Sasongko TH, Watihayati MS, Atif AB, Hayati F, Gunadi, et al.

Indian J Med Res, 2012;135:31-5.

Genetic diagnosis of spinal muscular atrophy (SMA) is complicated by the presence of SMN2 gene as majority of SMA patients show absence or deletion of SMN1 gene. PCR may amplify both the genes non selectively in presence of high amount of DNA. We evaluated whether allele-specific PCR for diagnostic screening of SMA is reliable in the presence of high amount of genomic DNA, which is commonly used when performing diagnostic screening using restriction enzymes.

Hyperargininemia is a very rare progressive neurometabolic disorder caused by deficiency of hepatic cytosolic arginase I, resulting from mutations in the ARG1 gene. Until now, some mutations were reported worldwide and none of them were of Southeast Asian origins. Furthermore, most reported mutations were point mutations and a few others deletions or insertions.

Fulltext Two novel gross deletions of TSC2 in Malaysian patients with tuberous sclerosis complex and TSC2/PKD1 contiguous deletion syndrome

Tuberous sclerosis complex is an autosomal dominant neurocutaneous disorder affecting multiple organs. Tuberous sclerosis complex is caused by mutation in either one of the two disease-causing genes, TSC1 or TSC2, encoding for hamartin and tuberin, respectively. TSC2/PKD1 contiguous gene deletion syndrome is a very rare condition due to deletion involving both TSC2 and PKD1 genes. Tuberous sclerosis complex cannot be easily diagnosed since there is no pathognomonic feature, although there are consensus diagnostic criteria for that. Mutation analysis is useful and plays important roles. We report here two novel gross deletions of TSC2 gene in Malay patients with tuberous sclerosis complex and TSC2/PKD1 contiguous gene deletion syndrome, respectively.

Asian Pac J Cancer Prev, 2017 07 27;18(7):1821-1825.

PMID: 28749112

Background: Anastomotic leaks in colorectal surgery results in a high morbidity and mortality rate. Serum procalcitonin levels is known as a sensitive and specific marker of sepsis and could be use as a marker for early detection of a leak allowing early intervention. It may help a clinician decide to perform a CT scan even earlier especially when the diagnosis of a leak is uncertain. The aim of this study is to determine whether serum procalcitonin is a good predictor of anastomotic leak in colorectal surgery. Methodology: Between July 2014 until October 2015, 70 patients undergoing colorectal surgery were prospectively analyzed in a single-center tertiary teaching hospital. Demographic and surgical data were obtained. Serum procalcitonin was taken before surgery and at day 3 (72 hours) postoperatively. During the postoperative period, the patients were observed in the ward for features of anastomotic leak and if present, it was managed accordingly. The primary outcome was to prospectively determine an association between serum procalcitonin levels and an anastomotic leak in patients who underwent colorectal surgery with a primary anastomosis. Result: The rate of anastomotic leak was 4.5% (3 patients) with a mortality rate of 4.3% (3 patients). A rise in serum procalcitonin was statistically significant among patients with anastomotic leak. The optimal procalcitonin cut-off level at postoperative day 3 was 5.27 ng/mL, resulting in 100% sensitivity, 85% specificity, 23% positive predictive value and 100% negative predictive value. Nevertheless, none of the variables showed statistical significance with an anastomotic leak. Conclusion: Procalcitonin is a reliable biochemical marker to help diagnose anastomotic leak in colorectal surgery. Our study has shown that a level of 5 times beyond normal is statistically significant and a value of more than 5.27 ng/mL is confirmatory of a leak.

A 46-year gentleman presented with a left-sided lumbar region pain without fever or dysuria. He denied episodes of acute urinary retention. There was a hard mass at the distal urethra with normal laboratory blood tests. Computed tomography urogram revealed a concurrent left renal staghorn calculus and large distal urethral stone. The urethral stone was fragmented via endourologic technique successfully. We report a case of a non-obstructing large urethral calculus in a gentleman with concurrent left renal staghorn calculus and discuss the literature review.

PMID: 29984337 DOI: 10.4111/icu.2018.59.4.232

Purpose: To evaluate the expression of estrogen receptor (ER)-beta and Ki67 in prostate cancer and study their relationship.

Materials and Methods: We analyzed 101 cases of prostate adenocarcinoma diagnosed from January 2011 to June 2015 in 100 patients. Immunohistochemical staining of ER-beta and Ki67 was analyzed according to Gleason score categorized into prognostic groups of 1 to 5. Double-immunofluorescent staining of ER-beta and Ki67 was performed in a total of 20 cases to study the co-expression and the relationship between these markers within the same tumor.

Results: A total of 53 of 101 cases (52.5%) were positive for ER-beta expression. There was a positive correlation whereby a high percentage of ER-beta expression was seen in the higher prognostic groups (groups 4 and 5; p=0.007). High Ki67 expression was observed in the higher prognostic group, whereas low Ki67 or negative expression was found in the lower prognostic group (p<0.001). The majority of cases evaluated with double-immunofluorescent staining (14/20) showed co-expression of ER-beta and Ki67 at the individual cell level.

Conclusions: ER-beta and Ki67 are independent tumor markers in high prognostic groups. Hence, co-expression of ER-beta and Ki67 indicates a more aggressive tumor with a poorer prognosis.

Inflammatory myofibroblastic tumour is rare but more common in children. It shows an immunophenotypic features of myofibroblastic differentiation, hence bearing neoplastic potential. The diagnosis is challenging especially if it involves rectum. Surgical resection is the mainstay of treatment if clinically obstructed. A 65-year-old gentleman presented with intestinal obstruction, which then followed by a hartmann's procedure. Final diagnosis is a rare case of inflammatory myofibroblastic tumour of the rectum. We discuss its genetic involvement with a literature review.

Asian J Endosc Surg, 2018 Nov;11(4):318-324.

PMID: 29424061 DOI: 10.1111/ases.12463

INTRODUCTION: Colonoscopy is the gold standard to detect colorectal neoplasm. Narrow-band imaging (NBI) has a good diagnostic accuracy to differentiate between neoplastic and non-neoplastic colorectal lesions. This study explores the diagnostic validity of NBI colonoscopy as well as its associated factors related to neoplastic and non-neoplastic colorectal lesions.

METHODS: This study enrolled 100 patients in a single-center tertiary teaching hospital. Patients presented for screening colonoscopy, and those with suspicious colorectal lesions were included in this study. During colonoscopy, the most suspicious lesion in each patient was analyzed using the NBI system based on Sano's classification. Each lesion was biopsied for histopathological analysis, the gold standard. Endoscopic images were captured electronically. The sensitivity, specificity, and diagnostic accuracy of NBI colonoscopy were assessed. Other associated factors related to neoplastic and non-neoplastic lesions were analyzed accordingly.

RESULTS: The sensitivity and specificity of the NBI were 88.2% and 71.9%, respectively. The area under the receiver-operator curve was 0.801, indicating that NBI has a good ability to differentiate between disease and non-disease. There are significant associations between histopathological examination outcomes and both presenting symptoms, especially weight loss, and lesion site, even after other variables were controlled (P

PMID: 29064546 DOI: 10.5603/FM.a2017.0097

We present the case of a 16-year-old boy presented with 2-week episode of wor-sening lower abdominal pain. Clinically, there was a tender palpable mass on the suprapubic region. Ultrasonography showed an absent spleen at its usual area, instead suprapubic mass suggestive of ectopic spleen was identified. An emer-gency laparotomy revealed a congested spleen in the pelvic cavity. Splenectomy was undertaken as it was non-viable. The patient was discharged uneventfully with triple vaccinations. We describe this unique entity with its literature review. (Folia Morphol 2018; 77, 2: 400-402).

PMID: 30319829 DOI: 10.1155/2018/4606259

Preputial calculus is a relative surgical rarity. It usually happens in elderly men with poor hygiene and uncircumcised penis complicated with phimosis. In the paediatric group, it is usually secondary to phimosis and other urologic and/or neurologic anomalies. Surgical treatment is the mainstay of treatment. Herein, we report a 27-year-old gentleman with preputial stone presented with obstructive uropathy and was successfully treated with surgical intervention. To the best of our knowledge, this is the first reported case of the largest preputial stone in Malaysia.

Endometrial stromal sarcoma (ESS) is a rare malignant tumour of the endometrium, accounts for less than 1% of all
uterine malignancies. Routinely, it is diagnosed morphologically, supported by immunomarkers of CD10 and
vimentin. CD56 is used widely in neuroendocrine tumour. In our current practice, CD56 is not used to support the
diagnosis of ESS. We present a case of a postmenopausal lady with advanced ESS who had expression of CD56

Sahid NA, Hayati F, Rao CV, Ramely R, Sani I, Dzulkarnaen A, et al.

Evid Based Complement Alternat Med, 2018;2018:3032790.

PMID: 30538757 DOI: 10.1155/2018/3032790

BACKGROUND: Snakehead fish (Channa striatus) is a fresh water fish indigenous to many Asia countries and believed to have medical value. Studies showed that it contains all the essential amino acids and fatty acids able to accelerate wound healing and it has antinociceptive effect. However, little human study has been done to assess the effectiveness of Channa striatus in wound healing. A prospective RCT has been conducted on the effect of Channa striatus spray versus placebo on clean wound to assess its pain control effect and cosmetic outcome.

METHODOLOGY: One hundred and two patients (102) underwent clean elective surgery; postoperatively they were randomized into two group. One group received Channa striatus extract spray (n=51) another group received placebo (n=51) on daily basis for 2 weeks. They were followed up on 2nd, 4th, and 6th weeks. Pain control effect was assessed based on Visual Analog Pain Score (VAPS) and cosmetic outcome based on Visual Analog Cosmetic Scale (VACS), Wound Evaluation Scale (WES), and Vancouver Scar Scale (VSS).

RESULT: The patient treated with Channa striatus spray displayed a better outcome in terms of pain control compared to placebo. During analysis using repeated measure ANOVA, there was significant difference of patient's pain score based on VAPS between Channa striatus spray and placebo (F-stat (df) = 4.80 (2), p-value = 0.010). For cosmetic outcome it showed a better result in Channa striatus spray group for all the 3-scoring system, VACS, (F-stat (df) = 2.68 (2) , p-value <0.001), WES (F-stat (df) = 3.09 (2), p-value = 0.048), and VSS (F-stat (df) = 1.72 (2) , p-value = 0.011).

CONCLUSION: Our study suggest that application of Channa striatus extract spray on clean wound has shown a significant better pain score result and cosmetic outcome on week 2, week 4, and week 6 comparatively with placebo.

PMID: 31537599 DOI: 10.1136/bcr-2019-231516

Florid papillomatosis (FP) of the nipple, or nipple adenoma, is a rare breast tumour, affecting middle-aged group population. A 46-year-old woman presented to us with a cauliflower-like FP of the right nipple with no blood stained discharge or breast lump. FP can be mistaken clinically for Paget's disease and occasionally misinterpreted as invasive ductal or intraductal carcinoma. Extensive intervention, correct diagnosis and prompt treatment are essential. Any breast pathology requires triple assessment including FP of the nipple. Once the diagnosis of ductal carcinoma is excluded, simple complete excision can be undertaken. This is to ensure complete obliteration of disease recurrence and preservation of cosmetic result. We discuss the pathology and psychosocial aspects of FP.

Fulltext Spontaneous Omental Infarction: An Unusual Etiology of Abdominal Pain

Khairuddin A, Teng WW, Azizan N, Hayati F, Sahid NA, Kadir F

Kathmandu Univ Med J (KUMJ), 2019 10 1;17(68):347-349.

PMID: 33311048

A 49-year-old lady with previous scars complained of acute abdominal pain for two days. Her right hypochondrium was tender and guarding upon assessment. The laboratory investigations were unremarkable. Due to a diagnostic incongruity, computed tomography of the abdomen was performed showing a suspicious lesion at anterolateral aspect of the ascending colon. Surgical intervention was decided and intraoperative finding was consistent with spontaneous omental infarction. Omentectomy was undertaken and final histology was compatible with the intraoperative diagnosis. Although it is exceptional, omental infarction should be considered as part of the differential diagnoses of right-sided acute abdominal pain with normal laboratory investigations. This case highlights its unexpected discovery and we describe its literature reviews.

Lim KJ, Cheng TTJ, Jeffree MS, Hayati F, Cheah PK, Nee KO, et al.

Transplant Proc, 2020 Apr;52(3):680-686.

PMID: 32146022 DOI: 10.1016/j.transproceed.2020.01.007

INTRODUCTION: Worldwide, the gap between organ supply and demand has widened over the years. Malaysia has one of the lowest deceased organ donation rates. Success rate of organ or tissue procurement depends on not only the approach rate by health care providers but also the awareness among the public, whereby it can be a platform for family initiation of organ donation. The purpose of this study is to assess the knowledge of and determine the factors influencing attitude toward organ and tissue donation among patients in a primary clinic.

METHODS: A cross-sectional analytical study was carried out. Self-administered questionnaires were given to 400 patients who registered at an outpatient clinic in April 2018. Convenience sampling was applied.

RESULTS: Monthly income, education level, occupation, and knowledge level are significantly associated with attitude of the respondents toward organ and tissue donation. Occupation influenced attitude toward organ donation. Knowledge of organ donation and brain death both significantly affected attitude toward organ donation.

CONCLUSION: The greater the knowledge of organ donation and brain death, the more positive impression or attitude toward organ donation. Education level and income are the main predictors that influence attitude toward organ donation. Hence, it is important for public health units to promote and deliver public education on organ donation, change public misconceptions, and work parallel with hospitals to increase organ donation rates in Sabah.
