Parotid gland surgery can be challenging due to intricate relationship between the gland and facial nerve. Besides complete removal of the lesion, the main focus of surgery is centered on the facial nerve. Surgery can be technically demanding especially when the tumor is large or involves the deep lobe. We report a patient with a 30-year history of gigantic parotid mass, which initial fine-needle aspiration cytology reported as pleomorphic adenoma. The tumor, weighing 1.3 kg, was successfully resected with facial nerve preservation. Histopathological examination of the excised mass confirmed as carcinoma ex pleomorphic adenoma (CaExPA) of adenocarcinoma, not otherwise specified type. We describe the specific surgical and reconstruction techniques for successful removal of large parotid tumors with facial nerve preservation. To our knowledge, this is the heaviest CaExPA of the parotid gland in South-East Asian region.

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.

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.

Auris Nasus Larynx, 2018 Dec;45(6):1183-1190.

PMID: 29880289 DOI: 10.1016/j.anl.2018.04.010

OBJECTIVE: This study was done to determine frontal recess anatomy cell variations and its association with frontal sinusitis. The incidence of frontal recess cells in the population, the presence of frontal recess cell variations in chronic rhinosinusitis and non-chronic rhinosinusitis and the association of frontal recess cell variation in the development of frontal sinusitis were also assessed.

METHODS: This was an observational, retrospective cross-sectional study of computed tomography (CT) scan of paranasal sinus that had been performed on patients in Hospital Universiti Sains Malaysia and Hospital Sultanah Bahiyah done from January 2009 until December 2016. The presence of frontal recess cells variation was compared with other populations.

RESULTS: A total of 312 sides from 156 patients' CT scan images were analyzed. Left and right sinuses were considered individually. A total of 63 sides showed evidence of frontal sinusitis, 37 were male and 26 were female, whereas 249 sides were clear from frontal sinus disease. It was not much difference in mean age for frontal sinusitis patient (46.51±14.00) and patients without frontal sinusitis (48.73±16.44). The percentage was almost equal for CRS and non-CRS groups regardless of side and gender. In our study, the frontal recess cell such as agger nasi cell was found in almost all patients 98.1%, frontal ethmoidal cell type 1, type 2, type 3 and type 4 comprised of 28.8%, 31.1%, 14.4% and 0% respectively. Whereas, suprabullar cell can be seen in 40.3%, supraorbital ethmoid cells 16.7%, frontal bullar cell 33.0% and inter-frontal sinus septal cells 10.8%. There was a statistically significant association between the presence of frontal bullar cell and the development of frontal sinusitis (p value<0.001).

CONCLUSION: The frontal recess cells variation in Malaysian subjects were almost similar to those reported in other Asian populations such as Japanese, Taiwanese, Chinese and Korean. Our study found that frontal bullar cells had a significant association with the development of frontal sinusitis than other frontal recess cells. The understanding of the frontal recess anatomical structures was very important as this would lead to a successful treatment of CRS and at the same time it helped the surgeon to have a better plan of endoscopic sinus surgery to prevent the disease recurrence and surgical complication.

A 24-year-old man presented to the casualty department with a history of left-sided, colicky abdominal pain for one day. It was associated with an inability to pass flatus or motion within the same duration. There was no history of vomiting. On examination, the vital signs were within normal limits, and he was afebrile. His abdomen was soft, but a hard mass was palpable on the left side of his abdomen. There was no peritonitis. The bowel sounds were sluggish.

Fulltext A food bolus obstructing the oesophagus in a patient with infantile cerebral palsy

Vong, K.S., Mohamad, I., Salim, R.

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

Noh, K.B., Salim, R., Abdullah, M.S., Mohamad, I.

Malaysian Family Physician, 2018;13(2):36-38.

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.

MyJurnal

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.

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.

Fulltext Bilateral peritonsillar abscess: A rare emergency

Boon C, Wan Mohamad WE, Mohamad I

Malays Fam Physician, 2018;13(1):41-44.

PMID: 29796210 MyJurnal

Peritonsillar abscess, or quinsy, is a rare complication of acute tonsillitis. It usually presents with odynophagia, trismus, and muffled voice, reflecting the space-occupying lesion in the oral cavity. Examination reveals a unilateral swelling on either side of the soft palate, which drains thick pus after an incision is made. It is regarded as an emergency as an upper airway obstruction can develop. Bilateral peritonsillar abscess is a rare presentation and results in catastrophic sequelae. We present a case of bilateral peritonsillar abscess that was initially referred by a primary care centre facing a dilemma in diagnosis. Prompt diagnosis and fast drainage are warranted to avoid unwanted morbidity, and, also, mortality.

AME Case Rep, 2018;2:4.

PMID: 30264000 DOI: 10.21037/acr.2018.01.06

Malignant melanoma (MM) of parotid gland is a rare condition. This pathology is often a result of secondary metastasis from primary lesions in the head and neck skin. A MM arising de novo in parotid gland is very rare. This malignant tumour is more prevalent in adults rather than children and it tends to have several distinct features. Treatment options are limited especially for an advanced lesion. Despite best treatments this condition carries a poor prognosis. This case details our experience in treating a child with MM of parotid gland without other primary cutaneous lesions.

PMID: 29387523 DOI: 10.1016/j.rmcr.2018.01.001

Introduction: Bronchoscopy is a commonly used procedure in the context of aspiration in the Intensive Care Unit setting. Despite its ability to remove mucus plug and undigested gastric contents, aspiration of gastric content into the trachea is one of the most feared complications among anesthesiologist.

Discussion: The scenario is made worst if the aspiration causes acute hypoxemic respiratory failure immediately post intubation. However, in the event of desaturation, the quick decision to proceed with bronchoscopy is a challenging task to the anesthesiologist without knowing the causes.

Case presentation: We present a case of a 12-year-old boy who had a difficult-to-ventilate scenario post transferring and immediately connected to ventilator in operation theatre (OT) from portable ventilator from the emergency department. She was successfully managed by bronchoscopy.

Conclusion: Special attention should be given to the difficult-to-ventilate scenario post intubation of traumatic brain injury patient prior to operation. Prompt diagnosis and bronchoscope-assisted removal of foreign body was found to be a successful to reduce morbidity and mortality.

Fulltext Nasopharyngeal Mantle Cell Lymphoma: An Extremely Rare Entity

Paul M, Asmi NH, Omar EK, Abdullah S, Mohamad I

Oman Med J, 2019 Jan;34(1):74-77.

PMID: 30671189 DOI: 10.5001/omj.2019.13

Mantle cell lymphoma (MCL) is a rare, aggressive subtype of non-Hodgkin lymphoma with a poor prognosis and high recurrence rate. It seldom affects the Waldeyer's ring let alone the nasopharynx. Patients usually present at late stages of the disease leading to poor failure-free and overall survival rates. Intensive chemotherapy regimes and autologous stem cell transplantation have reported increased survival rates. We report a relapsed case of nasopharyngeal MCL, which previously occurred in the gastrointestinal tract. The patient had undergone a hemicolectomy for colon intussusception secondary to the intraluminal lymphoma mass. He was unable to complete the treatment regime for MCL due to the adverse side effects. Oropharyngeal mass was discovered during routine outpatient follow-up, which was confirmed as nasopharyngeal MCL. We discuss the prognosis, disease progression, and possible treatments.

Paediatric burkitt lymphoma presenting as a mandible swelling and intussusception

Retinasekharan S, Sinnathamby P, Mohamad I

Med J Malaysia, 2019 02;74(1):90-91.

PMID: 30846671

Burkitt lymphoma is a rare entity especially in this part of the world. We had an 11-year-old patient presented with swelling of the mandible for a short one-month duration. He was planned for excision biopsy. However developed severe abdominal pain while in the hospital and was diagnosed as intussusception after ultrasound was done. We proceeded with right hemicolectomy and excision of buccal mass. Early recognition and close monitoring of insidious jaw lesions is recommended even in young adults not within the modal age category of endemic Burkitt.
