Malays Fam Physician, 2018;13(2):32-35.

Kimura disease presents as benign lesion and is commonly present among the Asian population. It is a disease with a favourable prognosis and a peak age of onset in the third decade. It is a chronic inflammatory disorder of unknown etiology that involves the lymph nodes and subcutaneous tissues of the head and neck region. We report a case of a 15-year-old boy with multiple Kimura lymphadenopathies involving the left posterior auricular region as well as the anterior and posterior triangles of the neck.

Cervical vagal schwannoma is an uncommon, benign neoplasm. It is usually asymptomatic and presents as a painless, palpable mass in the neck. However, large schwannomas can cause dysphagia, dysphonia or dyspnea as a result of compression. We report a case of an extremely rare complication of vagal schwannoma in which neck palpation induced the patient to cough. As the patient refused any surgical intervention, conservative management was used.

The louder the bigger: A case of jugular phlebectasia in a child

Kandiah R, Mohamad I

Malays Fam Physician, 2019;14(3):77-79.

PMID: 32175047

Jugular phlebectasia has been increasingly recognised with the advent of non-invasive diagnostic methods. Phlebectasia differs from varix, as it is an abnormal outward dilatation of a vein without tortuosity. It presents as a soft, compressible mass, apparent upon straining or execution of the Valsalva maneuver. The differentials for neck masses are broad, but if the swelling appears on the Valsalva maneuver, the type of mass narrows down to a laryngocele, superior mediastinal mass or phlebectasia. A simple non-invasive investigation, such as ultrasonography, is used as a diagnostic tool. We report a case of jugular phlebectasia that was suspected clinically and confirmed via ultrasound to be a vascular lesion which changed its size upon straining.

A previously healthy 80-year-old woman presented with a history of a thorn prick injury over the
distal phalange of her left finger obtained while gardening two months ago. She claimed to have a
non-healing cut with a nodular lesion, which progressively increased in size, extending upwards
towards the region of her left arm. There was no fever or palpable lymph nodes in the axillary region.
She had been prescribed antibiotics from the local hospital but her condition did not improve.

Fulltext A rare case of a sharp foreign body on the vocal cord

PMID: 29423126 MyJurnal

A foreign body (FB) in the upper aerodigestive tract is a common clinical problem that presents as as acute emergency. Sharp FB, such as fish bone or chicken bone, commonly lodges in the tonsil, base of tongue, vallecula or pyriform fossa. Dislodgement of a FB into the laryngopharynx is very rare and specifically onto the vocal cord is extremely uncommon. This case report illustrates a rare case of a sharp FB that was dislodged into the airway and stuck on to the right vocal cord, which was removed under local anaesthesia.

PMID: 28503275 MyJurnal

A 68-year-old Malay man who is a rubber tapper, presented with a large painful right-sided neck swelling for 6 months, which was gradually increasing in size and associated with odynophagia, dysphagia, hoarseness and significant weight loss. He did not complain of any ear symptoms, but on further questioning, he admitted having a 3-week history of occasional tinnitus and reduced hearing on the right ear. Other ear symptoms were negative.

MyJurnal

Subcutaneous emphysema can occur after a breach to the air-containing space. The classical condition will be ruptured alveolus in chronic lung disease. A disruption of the upper airway such as trauma to the laryngotracheal framework may lead to similar presentation. The amount of air leak varies depending on site and size of the breach. We report a case of blunt neck trauma after a fall from bicycle, which ended with massive subcutaneous emphysema, pneumothorax and pneumomediastinum requiring intubation.

Malaysian Family Physician, 2018;13(1):34-36.

MyJurnal

Introduction: A foreign body (FB) in the upper aerodigestive tract is a fairly common encounter.
Fish bones are the commonest FB seen in adults. The commonest presentation is odynophagia.
Usually, the patient will point at the level of FB on the neck to indicate the location.
Methods: Clinical report.
Results: This case report describes a large FB in an adult with underlying infantile cerebral palsy.
Besides dysphagia, it was associated with drooling of saliva and pain in the throat region.
Conclusion: FB ingestion with complete obstruction of the oesophagus is an emergency. It may
cause total dysphagia as the passage of food is completely blocked.

Fulltext Metallic hair pin aspiration into the left tertiary bronchus

MyJurnal

Foreign body aspiration is commonly described in infants and children. However, recently, a new
high-risk group was identified among young women, especially those from the Muslim population
who wear the traditional hair scarf. This is due to the habit of holding the scarf pin in between the
lips to free hands to adjust the scarf more easily. Talking, laughing, or coughing while fixing the
scarf may result in inadvertent inhalation of the pin into the tracheobronchial tree. We present a
case of scarf pin inhalation and the challenges encountered in managing this patient during the
successful removal of the pin via flexible bronchoscopy under fluoroscopy guidance. This particular
case was technically challenging for us as the sharp tip of the needle was pointing upward and
piercing the bronchial mucosa.

PMID: 28987252 DOI: 10.1016/j.jnma.2017.03.004

INTRODUCTION: Obstructive sleep apnea patients may develop deficits in the cognitive domains of attention, concentration, executive function, verbal and visuospatial memory, constructional abilities, and psychomotor functioning. As cognitive performance will improve with the treatment, early screening for cognitive dysfunction should be done to prevent further deterioration.

OBJECTIVE: We aim to evaluate the cognitive function of obstructive sleep apnea patients by using the 'Mini Mental State Examination'.

METHODOLOGY: This was a cross sectional study to evaluate the cognitive function of moderate and severe obstructive sleep apnea patients with age ranged from 18 to 60 old who attended our sleep clinic. These patients were confirmed to have moderate and severe obstructive sleep apnea by Type 1 polysomnography (attended full overnight study). The age, gender and ethnicity were noted and other relevant data such as weight, height, body mass index and apnea and hypopnoea index were recorded accordingly. The cognitive function was evaluated using validated Malay version of Mini Mental State Examination which measured 5 areas of cognitive functions comprising orientation, registration, attention and calculation, word recall and language abilities, and visuospatial.

RESULTS: A total of 38 patients participated in this study. All 19 patients of moderate group and 14 patients of severe group had normal cognitive function while only 5 patients in severe group had mild cognitive function impairment. There was a statistically significant difference between the moderate group and severe group on cognitive performance (p value = 0.042).

CONCLUSIONS: Severe obstructive sleep apnea patients may have impaired cognitive function. Mini Mental State Examination is useful in the screening of cognitive function of obstructive sleep apnea patients but in normal score, more sophisticated test batteries are required as it is unable to identify in 'very minimal' or 'extremely severe' cognitive dysfunction.

Single-nucleotide polymorphisms and mRNA expression of CYP1B1 influence treatment response in triple negative breast cancer patients undergoing chemotherapy

Triple negative breast cancer (TNBC) is typically associated with poor and interindividual variability in treatment response. Cytochrome P450 family 1 subfamily B1 (CYP1B1) is a metabolizing enzyme, involved in the biotransformation of xenobiotics and anticancer drugs. We hypothesized that, single-nucleotide polymorphisms (SNPs), CYP1B1 142 C>G, 4326 C>G and 4360 A>G, and CYP1B1 mRNA expression might be potential biomarkers for prediction of treatment response in TNBC patients. CYP1B1 SNPs genotyping (76 TNBC patients) was performed using allele-specific polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism methods and mRNA expression of CYP1B1 (41 formalin-fixed paraffin embeddedblocks) was quantified using quantitative reverse transcription PCR. Homozygous variant genotype (GG) and variant allele (G) of CYP1B1 4326C>G polymorphism showed significantly higher risk for development of resistance to chemotherapy with adjusted odds ratio (OR): 6.802 and 3.010, respectively. Whereas, CYP1B1 142 CG heterozygous genotype showed significant association with goodtreatment response with adjusted OR: 0.199. CYP1B1 142C-4326G haplotype was associated with higher risk for chemoresistance with OR: 2.579. Expression analysis revealed that the relative expression of CYP1B1 was downregulated (0.592) in cancerous tissue compared with normal adjacent tissues. When analysed for association with chemotherapy response, CYP1B1 expression was found to be significantly upregulated (3.256) in cancerous tissues of patients who did not respond as opposed to those of patients who showed response to chemotherapy. Our findings suggest that SNPs together with mRNA expression of CYP1B1 may be useful biomarkers to predict chemotherapy response in TNBC patients.

J Taibah Univ Med Sci, 2018 Aug;13(4):364-369.

PMID: 31435348 DOI: 10.1016/j.jtumed.2018.04.004

Objective: This study aimed to assess the effectiveness of nasal rinsing during ablution in reducing acute respiratory tract infection among male Hajj pilgrims.

Methods: A quasi-experimental trial study was conducted to compare the effectiveness of nasal rinsing between two groups. The intervention group was instructed to perform nasal rinsing during ablution, while the control group was not asked to do nasal rinsing. Both groups were provided progress diaries to record the symptoms of respiratory tract infection, including cough, rhinorrhoea, nasal blockage, fever, and sore throat, as well as thick phlegm, shortness of breath, epistaxis, and changes in sense of smell. The groups were also instructed to record any visits to clinics for their symptoms throughout their stay in Makkah for the Hajj ritual.

Results: The study showed that nasal rinsing significantly reduced the symptoms of cough, rhinorrhoea, and nasal blockage. The intervention group had an increased number of visits to healthcare facilities for treatment, when compared to those of the control group. There were no significant differences in the groups regarding the symptoms of fever and sore throat.

Conclusion: Nasal rinsing can be included as part of intervention methods that include vaccination and the use of a face mask. Nasal rinsing can be easily practiced by the pilgrims, since it is a Sunnah act in ablution, which is an integral element of Muslims' daily life.

Giant cell tumours are benign lesions that are uncommonly found in the larynx. Patients with these tumours may present with dysphagia, hoarseness and anterior neck swelling. Giant cell tumours are extremely rare and only a few cases have been reported. We present a case of an elderly woman who presented with severe dysphagia and a mass at the base of her tongue. The mass was found to be a laryngeal giant cell tumour and was successfully treated with chemotherapy.

Sudden Bilateral Sensorineural Hearing Loss Secondary to Cerebral Venous Thrombosis

PMID: 29594079

Introduction: Sudden sensorineural hearing loss (SSNHL) is an important otological emergency. Up to 90% of the cases are idiopathic. Cerebral venous thrombosis (CVT) is an extremely rare identifiable cause as it only represents 0.5% of all strokes.

Case Report: In this paper, an unusual case of bilateral SSNHL secondary to bilateral CVT with rapid and complete recovery is reported. The patient presented with sudden bilateral hearing loss associated with some neurological symptoms. Initial computed tomography (CT) venography revealed a CVT of bilateral transverse sinuses. The patient was started on an anticoagulant and imaging was repeated after five days, revealing the absence of the thrombosis. Serial pure tone audiometry (PTA) showed complete recovery of bilateral hearing within 10 days.

Conclusion: Early detection and intervention may fasten hearing recovery and improve the quality of life. The immediate restoration of venous blood flow and intracranial pressure may lead to the complete recovery of bilateral hearing loss.
