Fulltext The Development of Expanded Snack Product Made from Pumpkin Flour-Corn Grits: Effect of Extrusion Conditions and Formulations on Physical Characteristics and Microstructure

Nor NM, Carr A, Hardacre A, Brennan CS

Foods, 2013 May 14;2(2):160-169.
PMID: 28239106 DOI: 10.3390/foods2020160

Pumpkin products confer natural sweetness, desirable flavours and β-carotene, a vitamin A precursor when added as ingredients to extruded snacks. Therefore, a potential use for dried pumpkin flour is as an ingredient in ready-to-eat (RTE) snack foods. Growth in this market has driven food manufacturers to produce a variety of new high value snack foods incorporating diverse ingredients to enhance the appearance and nutritional properties of these foods. Ready-to-eat snacks were made by extruding corn grits with 5%, 10%, 15% and 20% of pumpkin flour. Snacks made from 100% corn grits were used as control products for this work. The effect of formulation and screw speeds of 250 rpm and 350 rpm on torque and specific mechanical energy (SME, kWh/kg), physical characteristics (expansion ratio, bulk density, true density and hardness) and the microstructure of the snacks were studied. Increasing the screw speed resulted in a decrease of torque for all formulations. When pumpkin flour was added the specific mechanical energy (SME) decreased by approximately 45%. Increasing the percentage of pumpkin flour at the higher screw speed resulted in a harder texture for the extruded products. X-ray tomography of pumpkin flour-corn grit snacks showed that increased levels of pumpkin flour decreased both the bubble area and bubble size. However, no significant differences (p > 0.05) in bubble wall thickness were measured. By understanding the conditions during extrusion, desirable nutritional characteristics can be incorporated while maximizing expansion to make a product with low bulk density, a fine bubble structure and acceptable organoleptic properties.

Coexistence of Colorectal Adenomas and Coronary Calcification in Asymptomatic Men and Women

Yun KE, Chang Y, Rampal S, Zhang Y, Cho J, Jung HS, et al.

J Clin Gastroenterol, 2018 07;52(6):508-514.
PMID: 28471937 DOI: 10.1097/MCG.0000000000000824

GOALS: Because of shared risk factors between clinically manifest cardiovascular disease and colorectal cancer, we hypothesized the coexistence of subclinical atherosclerosis measured by coronary artery calcium (CAC) and colorectal adenoma (CRA) and that these 2 processes would also share common risk factors.
BACKGROUND: No study has directly compared the risk factors associated with subclinical coronary atherosclerosis and CRA.
STUDY: This was a cross-sectional study using multinomial logistic regression analysis of 4859 adults who participated in a health screening examination (2010 to 2011; analysis 2014 to 2015). CAC scores were categorized as 0, 1 to 100, or >100. Colonoscopy results were categorized as absent, low-risk, or high-risk CRA.
RESULTS: The prevalence of CAC>0, CAC 1 to 100 and >100 was 13.0%, 11.0%, and 2.0%, respectively. The prevalence of any CRA, low-risk CRA, and high-risk CRA was 15.1%, 13.0%, and 2.1%, respectively. The adjusted odds ratios (95% confidence interval) for CAC>0 comparing participants with low-risk and high-risk CRA with those without any CRA were 1.35 (1.06-1.71) and 2.09 (1.29-3.39), respectively. Similarly, the adjusted odds ratios (95% confidence interval) for any CRA comparing participants with CAC 1 to 100 and CAC>100 with those with no CAC were 1.26 (1.00-1.6) and 2.07 (1.31-3.26), respectively. Age, smoking, diabetes, and family history of CRC were significantly associated with both conditions.
CONCLUSIONS: We observed a graded association between CAC and CRA in apparently healthy individuals. The coexistence of both conditions further emphasizes the need for more evidence of comprehensive approaches to screening and the need to consider the impact of the high risk of coexisting disease in individuals with CAC or CRA, instead of piecemeal approaches restricted to the detection of each disease independently.

Positron emission mammography is a useful adjunct in assessment of dense breasts

Kumar SK, Trujillo PB, Ucros GR

Med J Malaysia, 2017 04;72(2):138-140.
PMID: 28473683

Worldwide breast cancer remains as the most common malignancy in women and the numbers who form a subgroup with dense breast parenchyma are substantial. In addition to mammography, the adjuncts used for further evaluation of dense breasts have been anatomically based modalities such as ultrasound and magnetic resonance imaging. The practice of functionally based imaging of breasts is relatively new but has undergone rapid progress over the past few years with promising results. The value of positron emission mammography is demonstrated in patients with dense breasts and mammographically occult disease.

Malaysian Journal of Medicine and Health Sciences, 2015;11(2):89-92.
MyJurnal

Extracranial aneurysms are a rare presentation accounting for only less than 5% of all peripheral artery
aneurysms. The left common carotid artery aneurysm is considered even rarer. We present a case of a 46-year-old gentleman who presented to casualty unit with a neck mass, stridor and acute respiratory distress. Prior to this admission patient was being investigated for Takayasu arteritis (TA). Patient was subsequently intubated due to respiratory compromise. A CT angiography of the thorax was done
showed a proximal left common carotid artery aneurysm with contained leakage of aneurysm with
severe compression of the trachea. Patient was subsequently transferred to the vascular team in National Heart Institute for further management.

The optimal treatment for thoracolumbar fractures (TLF) without neurological deficit remains controversial. Majority of the systematic reviews and meta-analyses have evaluated open operative approaches but have yet to compare the outcomes of minimally invasive percutaneous pedicle fixation (MIPPF) versus non-operative treatment. A retrospective cohort study was performed to compare clinical and radiological outcomes between MIPPF and conservative groups for TLF AO Type A1 to Type B2 during a 2-year follow-up period. Pre-operative plain and CT films were evaluated and decision made for short segment (non-fusion) MIPPF. Patients who refused operation were treated conservatively with three months of body cast, brace, or corset. MIPPF group showed earlier Visual Analog Score(VAS) improvement at six months post-injury (0 vs 6.0- p<0.001), as well as better functional and radiological outcomes (p<0.050) at final follow-up. Progressions of regional kyphosis (RK) were noted in both groups but there was no significant difference within and between them(p>0.050). MIPPF as a method of internal bracing can be pursued in the treatment of TLF, with larger future cohorts and RCTs being called for to support and explore new findings.

Right iliac fossa pain can often be misdiagnosed as something sinister or benevolent despite assistance with state of the art imaging techniques. This is particularly more challenging in the female gender whereby the error of managing a right iliac fossa pain may approach forty percent. A 66-year-old lady, ten years post-menopause, presented with a week history of progressively worsening right iliac fossa pain. Malignancy was suspected with a palpable abdominal mass. Computed tomography was suggestive of an abscess collection, but a needle aspirate produced brown faecal material suggestive of a diverticulitis. An exploratory appendisectomy revealed a non malignant appendicular abscess. In conclusion, when clinical and imaging assessments are inconclusive, an exploratory laparotomy for a surgical excision is warranted primarily if malignancy is suspected.

Suraini, M. S., Bux, S. I.

Malaysian Journal of Medicine and Health Sciences, 2010;6(1):119-123.
MyJurnal

Introduction: Splenic pseudo-aneurysm is an uncommon complication following splenic injury caused by blunt abdominal trauma. Pseudo-aneurysm is usually treated with splenic arterial embolisation. Spontaneous thrombosis of a splenic pseudo-aneurysm can occur but it is rare. Method: We report a case of spontaneous thrombosis in a post-traumatic splenic pseudo-aneurysm. The patient was managed conservatively as he was haemodynamically stable with a repeat CT scan on the 7th day showing a tubular enhancing structure in the upper pole of the spleen demonstrating the same attenuation value .
Conclusion: This case illustrates a spontaneous resolution of splenic pseudo-aneurysm, which is a rare outcome of the condition.

Neurology Asia, 2015;20(2):191-195.
MyJurnal

Thrombosis of the deep cerebral venous system in the absence of superficial sinus thrombosis is a very rare disease. The clinical and radiological findings can be diagnostically challenging due to the subtle appearances on computed tomography (CT) scan. Magnetic resonance imaging (MRI) examination is a preferred imaging modality to complement the CT findings for an accurate diagnosis of venous sinus thrombosis. We present a case of this unusual condition which present as unilateral thalamic lesion on CT scan and the role of contrast enhanced MRI with fast spoiled gradient echo (FSPGR) sequence and 3D reconstruction which led to the diagnosis of thrombosis in the deep cerebral venous system.

Solitary adrenal metastasis is a rare presentation in breast cancer and it presents the clinician with a difficult therapeutic dilemma as there are no existing guidelines for optimal management. On literature review, we only found one published case report of solitary adrenal metastasis from infiltrating ductal carcinoma of the breast. Here we present a case of a 75 year-old lady who presented with a right breast lump which was subsequently confirmed to be infiltrating ductal carcinoma. She underwent a right mastectomy and axillary clearance. Computerised tomography (CT) staging revealed a solitary adrenal metastasis. She was treated with aromatase inhibitors and her tumour markers which were initially raised has now normalised.

This retrospective study is aimed at evaluating the role of CT scan in predicting parametrium involvement in early stage of cervical carcinoma. It was conducted in a Gynaecologic Oncology Centre, Hospital Alor Star from January 2004 till December 2008. All patients with operable stage I and II cervical cancer had pelvic CT scan for evaluation of parametrium involvement before undergoing radical hysterectomy and pelvic lymphadenectomy. Parametrial streakiness or presence of infiltration suggested local invasion. Following radical hysterectomy, the specimens sent for histological confirmation and the correlation between the CT scan finding and the histopathology result was studied. The result revealed a total of 104 patients with operable stage cervical carcinoma had pelvic CT scan. The sensitivity and the specificity of CT scan in assessing parametrial involvement was 33.3% and 84.8%, respectively. In conclusion, CT scan had high specificity but low sensitivity in determining parametrial involvement in early stage of cervical cancer. Hence, routine preoperative pelvic CT scan has a limited role in assessing parametrial involvement in early stage cervical carcinoma.

Mucoceles are expansile masses originating in the sinuses. They are relatively unusual, occurring most frequently at fronto-ethmoidal region. They are locally destructive. This expansile lesion caused bony erosion and displaces the adjacent structures. We report a case of a patient who presented to our clinic with bulging of his left eye and worsening of the left vision. This was preceded by history of sport injury to his left supraorbital ridge. CT scan revealed that there was an extraconal lesion at the superolateral part of the left orbital cavity which pushed the orbit inferomedially, which consistent with left frontomucocele. He underwent enucleation of the lesion via 3 windows created namely at the left supraorbital ridge, anterior table of left frontal sinus and through the septum separating the frontal sinuses.

Fulltext Morphology of maxillary first molars analyzed by cone-beam computed tomography among Malaysian: variations in the number of roots and canals and the incidence of fusion

Aws Hashim Al-Kadhim, Normaliza AB Malik, Azlan Jaafar, Zainul Ahmad Rajion

International Medical Journal Malaysia, 2017;16(2):33-39.
MyJurnal

Introduction: A few studies investigated the numerous potential endodontic uses of CBCT, including the
examination of root canal morphology and presumed that CBCT was effective for the initial identification of
such morphology; moreover CBCT is a reliable method for the detection of the MB2 canal when compared
with the gold standard of physical sectioning of the specimen. The aim of this study was to identify the root
and canal morphology of the maxillary first molars among Malaysians analysed by cone-beam computed
tomography (CBCT) images.

Materials and Methods: Maxillary first (n = 421) molars from Malaysian patients
(n = 241) of Malay, Chinese and Indians inceptions were examined by two Endodontists using in vivo CBCT
methods. The number and configuration of roots, the number of root canals, and the canal configuration
according to Vertucci’s classification were determined.

Results: Single roots were not found in maxillary
first molars. The incidence of fused roots was 1.995% in the first molars between mesiobuccal and
distobuccal roots. In (421) 3-rooted maxillary first molars, additional canals were found in 45.6% of the
mesiobuccal (MB) roots and 0% of the distobuccal (DB) roots. Bilateral symmetry of the MB roots was found
in 82.36% of the first molar. Only one tooth was found to have pulp stone inside the pulp chamber.

Conclusions: The root and canal configuration of a Malaysian population showed different features from
those of other populations. CBCT scans can enhance the understanding of root canal anatomy, with the
potential of improving the outcome of endodontic treatment.

Introduction: The mental foramen is present on either side of the body of the mandible bone. This foramen
transmits mental vessels and nerves. In forensic anthropology, mental foramen may be important for
differentiating sex, estimating age and identifying various races based on morphology. The main aim of the
present study was to determine the position, shape and diameter of the mental foramen according to sex,
age and race by postmortem computed tomography in the Malaysian population.

Materials and Methods: A total of 79 dentulous patients (48 males, 31 females) from 3 age groups (18-30 years, 31– 50 years, 51-74
years) were selected for this study, and ten parameters were observed for each mandible. The parameters
were divided into two morphological and eight morphometric parameters. The morphometric parameters
were measured by using Osirix MD Software 3D Volume Rendering.

Results: Results showed that mandibular
body length and height were significantly greater in males than in females by independent t-test. (p< 0.05).
However, the mandibular body height was found to decrease significantly with age in both sexes by one-way
Anova. It was observed that the shape of mental foramen was 45.6% oval and 54.4% rounded. About 44.3% of
them were in line with the longitudinal axis of the second premolar tooth.

Conclusion: It was concluded that
mental foramen may be used for identification purposes, particularly for sex, age and race determination.

Abdul Rashid AM, Md Noh MSF

BMC Neurol, 2018 May 29;18(1):76.
PMID: 29843624 DOI: 10.1186/s12883-018-1079-3

BACKGROUND: Dyke-Davidoff-Masson syndrome is a rare condition of unknown frequency resulting from brain injury due to a multitude of causes; especially in early life. Characteristics include cerebral hemiatrophy/hypoplasia, contralateral hemiparesis, seizures, and compensatory osseous hypertrophy.
CASE PRESENTATION: We present a case of a 13-year-old girl who initially presented with headaches, followed by episodic complex-partial seizures; which was controlled via medication. She also had right sided hemiparesis. Computed tomography (CT) showed evidence of left parieto-temporal infarct with cerebral atrophy. Complementary magnetic resonance imaging (MRI) did not reveal additional information. Workup for young stroke was negative. Upon further evaluation by Neuroradiology, features suggesting Dyke-Davidoff-Masson syndrome were confirmed. Patient has been under Neurology follow up since.
CONCLUSIONS: Due to its rarity, Dyke-Davidoff-Masson syndrome may easily be missed by the majority of treating clinicians. Knowledge of its features on imaging enables timely and accurate diagnosis - allowing appropriate management.

MyJurnal

We report a case of a giant bullous emphysema misdiagnosed as a pneumothorax. A 18-year-old chronic smoker presented with right sided chest pain and dyspnoea. Initial respiratory rate was 35 /min, blood pressure was 136/90 mmHg, heart rate 80/min and SpO2 was 98% on room air. Clinical examination revealed reduced right air entry and left trachea deviation. Chest X-ray helped to arrive at a diagnosis of pneumothorax. Needle aspiration was then performed followed by a chest tube thoracostomy because of no improvement. Massive amount of blood was drained and patient deteriorated further. CT thorax revealed a right haemopneumothorax with multiple bullaes. Patient was rushed to OT for emergency thoracotomy for stapling of the ruptured bullae. Giant bullous emphysema can mimic pneumothorax and physician must be vigilant if draining a suspected pneumothorax.

Fulltext Undiagnosed traumatic diaphragmatic hernia in two cats

Lau , S.F.

Jurnal Veterinar Malaysia, 2016;28(1):12-15.
MyJurnal

Two cases of diaphragmatic hernia in cats caused by road traffic accident were undiagnosed during the initial presentation. Both cats showed no evidence of respiratory distress and clinicians did not notice the diaphragmatic hernia on thoracic radiographs. Later on, both cats showed signs of dyspnea and diaphragmatic hernia was diagnosed with repeated thoracic radiograph and ultrasound. Diaphragmatic hernia is rather common in veterinary practice, however, its diagnosis can be clinically challenging. This case report highlights the importance to re-evaluate and monitor the patient closely after the traffic accident. Repeated radiograph, different diagnostic modalities and techniques such as ultrasound, computed tomography and positive contrast peritoneagraphy should be used in order to diagnose the diaphragmatic hernia conclusively.

MyJurnal

Schizencephaly is an uncommon congenital malformation of the central
nervous system which affects the development of the cerebral cortex. It is
defined as the gray matter lined filled cleft with cerebrospinal fluid that
extends from the pial surface to the ventricle. There exists a paucity in
scientific literature regarding the association between schizencephaly and
psychosis. We report a case of a 36-year-old male, presented with worsening
crisis of aggression, disorganized behavior and auditory hallucinations over
20 years. CT brain scan revealed unilateral left open lip schizencephaly, a
finding during his recent admission to the psychiatry ward.
