    Methicillin-resistant Staphylococcus aureus (MRSA) infection is important among vas-cular surgical patients. Its effect can be devastating resulting in limb amputation and mortality. We performed a retrospective patients record analysis to determine the pat-tern of MRSA infection among vascular surgical patients in Hospital Kuala Lumpur from January 2005 to December 2007. We also attempted to identify the factors asso-ciated with poor clinical outcome after such infection. There were 999 patients who underwent vascular surgeries in HKL within  the analysis period. Of these 24 patients (2.4%) were detected to have MRSA surgical site infection. The infection was commoner among cigarette smokers, patients with diabetes melitus and those who had previous vascular surgery. Most infections occurred in the emergency surgery category and manifested as wound breakdown. Fifty-four percent of the infected pa-tients ended with graft removal, amputations or death. MRSA infection complicating vascular surgery resulted in poor clinical outcome. This serious threat requires intensi-fied preventive measures.

    Angiosarcoma is one of the rarest types of malignant vascular tumours that involved the head and neck region. It predominantly affects the scalp and superficial soft tissues. Angiosarcoma arising from the deep cervical soft tissue is extremely rare. There is a limited literature on neck angiosarcoma that occurred simultaneously with papillary thyroid carcinoma. We report a rare case of concurrent papillary thyroid carcinoma and cervical epithelioid angiosarcoma, and postoperative rapid progression of residual angiosarcoma that mimicked a neck haematoma. The diagnostic challenge and possible etiologies have been discussed here.

    BACKGROUND: Neurofibromas are benign peripheral nerve sheath tumours. Hypoglossal nerve neurofibromas in cervical region are relatively rare, bilateral occurrence is extremely rare.

    METHODS: A 32-year-old man with type 1 neurofibromatosis presented with bilateral neck masses. Magnetic resonance imaging showed parapharyngeal masses consistent with neurogenic tumours, most likely neurofibromas.

    RESULTS: Surgical exploration through lateral cervical approach revealed unexpected finding of the tumour that arose from the hypoglossal nerve. The tumour had totally engulfed the nerve with no normal nerve fascicles identifiable, thus resected in toto. In the postoperative course, the patient developed right hypoglossal palsy and vocal fold palsy treated with augmentation of the paralysed vocal fold with temporary injection material.

    CONCLUSIONS: The authors described a patient with type 1 neurofibromatosis with neurofibroma originating from cervical part of hypoglossal nerve. This paper discussed this rare condition and the management on how to improve the treatment outcome.

    BACKGROUND: Hypopharyngeal carcinoma can involve thyroid gland due to their close proximity. However, an initial presentation as a thyroid abscess is rare in this malignancy. To our knowledge, this is the second reported case in the English literature.

    CASE PRESENTATION: We described a 45-year-old female who presented with dysphagia, hoarseness and anterior neck swelling. The initial CT scan revealed a right thyroid abscess which was incised and drained with no malignancy found in the biopsy of the thyroid tissue. Patient presented one month later with worsening dysphagia, weight loss and a fungating anterior neck mass. Further investigation revealed a locally advanced hypopharyngeal squamous cell carcinoma extending to the right thyroid, upper oesophagus, prevertebral muscles and bilateral cervical lymph nodes (T4bN2cM0). Unfortunately, the patient passed away prior to initiation of treatment.

    CONCLUSION: Clinicians should have raised index of suspicion of a possible underlying hypopharyngeal carcinoma in patients presenting with thyroid abscess and proceed to further investigations in order to ensure early diagnosis and treatment of the malignancy.

    BACKGROUND: Conditions causing stridor in paediatric patients can range from minor illnesses to life-threatening disorders. Proper evaluation and correct diagnosis are essential for timely intervention. The objective of this study was to determine the aetiological profiles and the management of paediatric patients with stridor referred to the Otorhinolaryngology Department of Hospital Serdang.

    METHODS: Medical records of all paediatric patients presenting with symptom of stridor from January 2010 to February 2015 were reviewed retrospectively. The patients' demographic data, clinical notes, laryngoscope findings, diagnosis and management were retrieved and analysed.

    RESULTS: Out of the total 137 patients referred for noisy breathing, 121 patients had stridor and were included in this study. There were 73 males and 48 females-most were of Malay ethnicity (77.7%). The age of presentation ranged from newborn to 10 years, with a mean of 4.9 months. Eighteen patients (14.9%) had associated congenital pathologies. The majority were congenital causes (90.9%), in which laryngomalacia was the commonest (78.5%), followed by subglottic stenosis (5.0%), vallecular cyst (2.5%) and congenital vocal fold paralysis (2.5%). Twelve patients (9.9%) had synchronous airway lesion. The majority of the patients were managed conservatively. Thirty-one patients (25.6%) required surgical intervention, of which only one needed tracheostomy.

    CONCLUSION: Laryngomalacia was the commonest cause of stridor among paediatric patients. A synchronous airway lesion should be considered if the child has persistent or severe symptoms. The majority of the patients were managed conservatively.

    INTRODUCTION: To review the present literature on upper respiratory tract sampling in COVID-19 and provide recommendations to improve healthcare practices and directions in future studies.

    METHODS: Twelve relevant manuscripts were sourced from a total of 7288 search results obtained using PubMed, Medline and Google Scholar. The search keywords used were COVID-19, nasopharyngeal, oropharyngeal, swabs, SARS and CoV2. Original manuscripts were obtained and analysed by all authors. The review included manuscripts which have not undergone rigorous peer-review process in view of the magnitude of the topic discussed.

    RESULTS: The viral load of SARS-CoV-2 RNA in the upper respiratory tract was significantly higher during the first week and peaked at 4-6 days after onset of symptoms, during which it can be potentially sampled. Nasopharyngeal swab has demonstrated higher viral load than oropharyngeal swab, where the difference in paired samples is best seen at 0-9 days after the onset of illness. Sensitivity of nasopharyngeal swab was higher than oropharyngeal swabs in COVID-19 patients. Patient self-collected throat washing has been shown to contain higher viral load than nasopharyngeal or oropharyngeal swab, with significantly higher sensitivity when compared with paired nasopharyngeal swab.

    RECOMMENDATIONS: Routine nasopharyngeal swab of suspected COVID-19 infection should take anatomy of the nasal cavity into consideration to increase patient comfort and diagnostic yield. Routine oropharyngeal swab should be replaced by throat washing which has demonstrated better diagnostic accuracy, and it is safe towards others.

    INTRODUCTION: Incidental fish bone ingestion may penetrate the upper aerodigestive tract and cause extraluminal migration due to late presentation or missed diagnosis. The migrated fish bone exhibits a wide spectrum of clinical manifestations, ranging from mild symptoms to potentially fatal complications.

    PRESENTATION OF CASE: We report three cases of extraluminal fish bone migration with diverse clinical presentations and complications. The first patient had mild throat symptoms and a fish bone that travelled through the neck and migrated towards the subcutaneous tissue without causing complications. The second patient developed deep neck abscess and thoracic complications as a result of the migrated foreign body, but recovered after surgical exploration and foreign body removal. The third patient presented late in sepsis and upper airway obstruction, subsequently succumbed to multiorgan failure before any surgical intervention.

    DISCUSSION: Thorough physical and endoscopy examinations are essential in patients with fish bone ingestion. Normal endoscopic findings in a symptomatic patient should always raise the suspicion of a migrated fish bone. A radiographic imaging study is often helpful in locating the foreign body and potential complications. The migrated fish bone that acts as the source of infection in the neck should be traced and removed surgically. The resulting abscess, if present, must be drained. The management of a migrated fish bone can be challenging and often require multi-discipline collaboration.

    CONCLUSION: The migration of the ingested fish bone outside the upper aerodigestive tract can cause serious complications and death in some cases. Clinicians should always maintain a high level of suspicion towards extraluminal migration in a patient with a history of fish bone ingestions but normal endoscopic findings. We emphasize the importance of early recognition and prompt surgical intervention to remove the migrated fish bone to minimise the potential morbidity and mortality.

    INTRODUCTION: Multiple anecdotal reports suggest that smell and taste loss were early subclinical symptoms of COVID-19 patients. The objective of this review was to identify the incidence of smell and taste dysfunction in COVID-19, determine the onset of their symptoms and the risk factors of anosmia, hyposmia, ageusia or dysgeusia for COVID-19 infection.

    METHODS: We searched the PubMed and Google Scholar on 15th May 2020, with search terms including SARS-COV-2, coronavirus, COVID-19, hyposmia, anosmia, ageusia and dysgeusia. The articles included were cross sectional studies, observational studies and retrospective or prospective audits, letters to editor and short communications that included a study of a cohort of patients. Case reports, case-series and interventional studies were excluded.

    DISCUSSION: A total of 16 studies were selected. Incidence of smell and taste dysfunction was higher in Europe (34 to 86%), North America (19 to 71%) and the Middle East (36 to 98%) when compared to the Asian cohorts (11 to 15%) in COVID-19 positive patients. Incidence of smell and taste dysfunction in COVID-19 negative patients was low in comparison (12 to 27%). Total incidence of smell and taste dysfunction from COVID-19 positive and negative patients from seven studies was 20% and 10% respectively. Symptoms may appear just before, concomitantly, or immediately after the onset of the usual symptoms. Occurs predominantly in females. When occurring immediately after the onset of the usual symptoms, the median time of onset was 3.3 to 4.4 days. Symptoms persist for a period of seven to 14 days. Patients with smell and taste dysfunction were reported to have a six to ten-fold odds of having COVID-19.

    CONCLUSION: Smell and taste dysfunction has a high incidence in Europe, North America, and the Middle East. The incidence was lower in the Asia region. It is a strong risk factor for COVID-19. It may be the only symptom and should be added to the list of symptoms when screening for COVID- 19.
