CT scanning deliver much higher radiation doses than planar radiological procedures, which puts patients to high risks. This study measures and evaluates patient doses during chest and abdomen computed tomography procedures. Particular attention is given to measuring the dose to the equivalent breast (mSv) and to estimate the associated risks of breast cancer to young female patients (15-35 years). Data was obtained from standard examinations from three hospitals. The measured values of CT dose indexes, CTDI (mGy) as well as exposure-related parameters were used for assessment. Breast and effective doses were extrapolated using a software. The results showed remarkable variations of the mean organ equivalent doses for similar CT examinations in the studied hospitals. This could be attributed to the variation in CT scanning imaging technique, and clinical indications. The average effective dose to the chest was 7.9 mSv (2.3-47.0 mSv) and for the abdomen the mean dose was 6.6 mSv, ranging from (3.3-27 mSv). The breast received equivalent doses from chest and abdomen procedures as follows: 10.2 (1.6-33 mSv) and 10.1(2.3-19 mS) Sv respectively. Each procedure yielded high risks of breast cancer for young females. Implementation of accurate referral criteria is recommended to avoid unnecessary breast radiation exposure.

Urban cities are synonym with a high incidence of penetrating chest injuries either from accidents or interpersonal violence. The outcome of penetrating chest wound can vary from immediate death to a prolonged morbidity. We here report a case of 39-year-gentleman who presented to Emergency Department Hospital Raja Permaisuri Bainun, Ipoh, Perak after being stabbed to the chest. His anterior penetrating chest wound was located at the 5th intercostal space medial to the midclavicular line. The stab wound penetrated the myocardium, causing minimal myocardial rupture. He also suffered from left haemothorax and hemopericardium. The haemothorax was drained with insertion of 32 French chest tube. The patient was admitted under the cardiothoracic team and discharged five days later without surgical intervention. He presented again to the Emergency Department with complains of shortness of breath and pleuritic pain. A left ventricular thrombus was detected via echocardiography. Unfortunately, he took his own discharge. Five days later he came again to Emergency Department with sporadic of loss of vision. The mural thrombus dislodged and embolized to the retinal artery causing amaurosis fugax. The patient was treated with aspirin 150mg and his symptoms subsequently resolved.

Fulltext An Accidental Finding of Pulmonary Sequestration in an Adult

MyJurnal

Pulmonary sequestration is defined as a segment of ç separated from the tracheobronchial tree and receiving its blood supply from a systemic artery rather than a pulmonary arterial branch. Classically, it has been described in two forms: (1) intralobar sequestration (ILS), in which the sequestrated part of lung lies within normal pulmonary visceral pleura, and (2) extralobar sequestration (ELS), in which the abnormal segment of lung is completely separate and enclosed in its own pleural investment. The term sequestration was coined by Pryce in 1946 to describe a disconnected bronchopulmonary mass or cyst with an anomalous systemic artery. Since this original description, terminology has become confusing as investigator has recognized many variants of sequestration not strictly meeting the original description. The spectrum now recognized as a continuum, with normal vessels supplying abnormal lung at one end and abnormal vessels supplying normal lung at the other end. Recently, we incidentally found an asymptomatic, intralobar pulmonary sequestration during CT pneumocolon.

Introduction: Ductal Eccrine carcinoma (DEC) is a rare primary cutaneous tumor that exhibits both squamous and adnexal ductal differentiation. Due to its rarity in clinical practice we present as case of DEC and a literature review on the latest management of this rare disease.
Case presentation: We report a case 41 years old female presented with lesion on the scalp and sternal mass, increasing in size with itchiness and erythematous for 6 months duration. Further CECT scan of brain and neck shows features of malignant left frontal scalp lesion with poor plane with overlying skin and underlying skull bone and CECT of thorax shows a large, irregular heterogeneously enhancing mass with necrotic center noted at right hilar within superior segment of right lower lobe, encasing right middle and lower lobe bronchi. Wedge biopsy of scalp lesion showed an intradermal lesion extensively infiltrating by malignant gland accompanied by desmoplasia and the tumor cells are seen extending into the surgical margins suggestive of ductal eccrine carcinoma.Clinical Discussion:This case highlights the importance and challenges in achieving early diagnosis coupled with the scarcity of information on these leads to difficulty in managing this patient.
Conclusion: In managing Ductal Eccrine Carcinoma tumor, standard method of treatment for has not been established. However, wide surgical excision is the treatment of choice for localized lesions. Regarding prognosis, there is conflicting data published which we describe in this article.

Asian Spine J, 2019 Apr;13(2):216-224.
PMID: 30472823 DOI: 10.31616/asj.2018.0151

STUDY DESIGN: Prospective study.
PURPOSE: To compare patients' and parents' perceptions of physical attributes (PAs) of adolescent idiopathic scoliosis (AIS) patients and to report any correlations between their perceptions and Scoliosis Research Society-22r (SRS-22r) scores.
OVERVIEW OF LITERATURE: Few studies have looked into the differences between patients' and parents' perceptions of their appearance.
METHODS: AIS patient-parent pairs (n=170) were recruited. The patients' and parents' perceptions of six PAs were evaluated: waist asymmetry (WA), rib hump (RH), shoulder asymmetry (SA), neck tilt, breast asymmetry (BrA), and chest prominence. These PAs were ranked, and an aggregate PA (Agg-PA) score was derived from a score assigned to the attribute (6 for the most important PA and 1 for the least important). The patients also completed the SRS-22r questionnaire.
RESULTS: Ninety-nine patients (58.2%) and 71 patients (41.8%) had thoracic and lumbar major curves, respectively. WA was ranked first by 54 patients (31.8%) and 50 parents (29.4%), whereas RH was ranked first by 50 patients (29.4%) and 38 parents (22.4%). The overall Agg-PA scores were similar for patients and parents (p>0.05). However, for thoracic major curves (TMCs) >40°, a significant difference was noted between the Agg-PA scores of patients and parents for SA (3.5±1.6 vs. 4.2±1.6, p=0.041) and BrA (3.0±1.6 vs. 2.2±1.3, p=0.006). For TMCs <40°, a significant difference was found between the Agg-PA scores of patients and parents for WA (3.7±1.6 vs. 4.4±1.5, p=0.050). BrA was negatively correlated with total SRS-22r score.
CONCLUSIONS: There were no significant differences between patients and parents in their ranking of the most important PAs. For TMCs >40°, there were significant differences in the Agg-PA for SA and BrA. Pa¬tients were more concerned about BrA and parents were more concerned about SA. Patients' perception of the six PAs had weak correlation with SRS-22r scores.

Working in a safe working posture is a necessity to enhance occupational health of industrial workers. Poor
working posture may lead to injuries, discomfort and fatigue to the workers. The objective of this study is to survey the
postures practised by the Malaysian industrial workers. A questionnaire survey was performed among 282 Malaysian
industrial workers in 10 different industries. From the answered questionnaire, it was observed that shoulder at chest
level (30.1%), back in a bent forward (33.3%) and lifting heavy load (44.7%) are the major work postures practised by
most of industrial workers. This survey identifies that working with shoulder and hand at chest level and back region
moderately bent forward is the main working posture practice by worker. Workers also reported lifting load below 5 kg
at the workstation. This survey recommended for industrial workers to be aware of the comfortable working posture
to avoid injury.

PMID: 26162385 MyJurnal

Hibernoma is a slow growing, rare benign tumour, which derived from brown adipose tissue. This tumour is usually found in the area where foetal fat persists such as back, axilla, retro peritoneum and thorax. Hibernoma rarely occurs in the retro pharynx. We report a case of retropharyngeal hibernoma in a 44-year-old male. He presented with obstructive symptoms for six months and a retropharyngeal mass upon examination. His CT scan findings showed a mass in the prevertebral region from level of C2 until C5 causing narrowing of upper aero digestive tract. Histopathological examination reported as hibernoma.

Primary pleural synovial sarcoma (PPSS) is an extremely rare malignancy without a known cause. The diagnosis is made after excluding metastasis from an extra-thoracic sarcoma. We report a case of a 67-year-old gentleman who presented with an incidental finding of a left lung mass on a routine chest X-ray. A computed tomography (CT) of the thorax and whole-body positron emission tomography (PET)-CT was done confirming a left lung mass with no other extra-thoracic involvement. A lobectomy was performed with a diagnostic and therapeutic intent. The histopathological examination and immunohistochemistry study revealed a pleural-based tumour with features suggestive of synovial sarcoma. Subsequently, he underwent post-operative radiotherapy. However, three months later, he developed an endobronchial recurrence, complicated by post-obstructive pneumonia resulting in his demise. This case highlights a rare form of malignancy with a rare site of recurrence.

Lymphangioleiomyomatosis (LAM) is a rare disease. The reported prevalence is around one per million in the West but the exact prevalence in Asia is unknown. It affects primarily young women of reproductive age, with a mean age of onset at 34 years. The disease is characterised by an abnormal proliferation of smooth muscle-like cells that grow over a course of time to obstruct airways, lymphatic and blood vessels. We report a case of LAM in a young woman who presented with a spontaneous pneumothorax. Computed tomography scan of the thorax and abdomen showed homogenous thin-walled cystic lesions with normal intervening lung parenchyma and multiple lesions in her kidneys with Hounsfield units similar to that of fat.

PMID: 25606297 MyJurnal

A 30-year-old Iban woman presented to a rural primary healthcare clinic located along the Batang Rejang in Sarawak. She had a 2-day history of rash, which started over her trunk and later spread to her face and limbs. What started out as individual erythematous maculopapular spots later coalesced to form larger raised blotches. The rash was extremely pruritic and affected her sleep, and hence her visit. The rash was preceded by high grade, persistent fever that was temporarily relieved by paracetamol. She also complained of malaise, arthralgia and myalgia. Her appetite had been poor since the onset of the fever. She lived in a long house at the edge of the jungle. Although she did not have a history of going into the jungle to forage, she went regularly to the river to wash clothes. Clinically, she appeared lethargic and had bilateral conjunctival injection. Her left anterior cervical lymph nodes were palpable. There were erythematous macules measuring 5 to 15 mm distributed over her whole body but predominantly over the chest and abdominal region (Figure 1). An unusual skin lesion was discovered at the right hypochondriac region. This lesion resembled a cigarette burn with a necrotic centre (Figure 2). There was no evidence of hepato-splenomegaly. Examination of the other systems was unremarkable. On further questioning, the patient admitted being bitten by a ‘kutu babi’ or mite 3 days before the onset of her fever.
