Med J Malaysia, 2012 Oct;67(5):491-3.

Fish is one of the major sources of protein among Malaysians. This has made incidents of fish bones lodged in the throat fairly common clinical problems. Plain radiograph, which is the first line of imaging in such cases, has been reported to have low sensitivity. Besides the location, the degree of radio-opacity of the bone is another important factor and is species dependent. This study was undertaken to determine the radio-opacity of bones from commonly consumed fish in Malaysia. A total of 15 types of fish were identified, six of them were opaque even when embedded and three were visualized in the simulated airway. In terms of radio-opacity, the commonly consumed fish in Malaysia possessed opaque bones and this fact can help doctors identify the location of the foreign body in the throat.

Fulltext Effects of mandibular setback with or without maxillary advancement osteotomies on pharyngeal airways: An overview of systematic reviews

Tan SK, Leung WK, Tang ATH, Zwahlen RA

PLoS One, 2017;12(10):e0185951.

PMID: 29016682 DOI: 10.1371/journal.pone.0185951

BACKGROUND: Mandibular setback osteotomies potentially lead to narrowing of the pharyngeal airways, subsequently resulting in post-surgical obstructive sleep apnea (OSA).

OBJECTIVE: To summarize current evidence from systematic reviews that has evaluated pharyngeal airway changes after mandibular setback with or without concomitant upper jaw osteotomies.

METHODOLOGY: PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched with no restriction of language or date. Systematic reviews studying changes in pharyngeal airway dimensions and respiratory parameters after mandibular setback with or without concomitant upper jaw osteotomies have been identified, screened for eligibility, included and analyzed in this study.

RESULTS: Six systematic reviews have been included. While isolated mandibular setback osteotomies result in reduced oropharyngeal airway dimensions, the reduction is lesser in cases with concomitant upper jaw osteotomies. Only scarce evidence exists currently to what happens to naso- and hypo-pharyngeal airways. There is no evidence for post-surgical OSA, even though some studies reported reduced respiratory parameters after single-jaw mandibular setback with or without concomitant upper jaw osteotomies.

CONCLUSION: Although mandibular setback osteotomies reduce pharyngeal airway dimensions, evidence confirming post-surgical OSA was not found. Nevertheless, potential post-surgical OSA should be taken into serious consideration during the treatment planning of particular orthognathic cases. As moderate evidence exists that double-jaw surgeries lead to less compromised post-surgical pharyngeal airways, they should be considered as the method of choice especially in cases with severe dentoskeletal Class III deformity.

Fulltext An elderly man with acute anterior neck pain and odynophagia after a meal

Mohamad I, Jaafar R

Malays Fam Physician, 2013;8(3):37-9.

PMID: 25893057 MyJurnal

The upper aerodigestive tract, specifically the cricopharyngeal area, is the most common site of foreign body impaction. Anatomically, this area is the first constriction of the oesophagus. Fish bones, one of the most common foreign bodies encountered in the throat, tend to get stuck in this area. The movement of this sharp-edged foreign body upon swallowing will induce odynophagia and an acute onset of neck pain. We report a case of a healthy elderly man who complained of sudden anterior neck pain and odynophagia after eating yellowtail scad fish.

Eagle's syndrome represents a symptomatic styloid process elongation or calcification of stylohyoid or stylomandibular ligament. The symptoms include the throat pain radiating to ipsilateral ear or foreign body sensation in the pharynx causing odynophagia and dysphagia. It is commonly unilateral and bilateral cases are rare. We report a case of bilateral elongation of styloid processes treated surgically by transoral approach.

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.

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 Observations of travelling ionospheric disturbances during storm events over Antarctica

Momani, M.A., Yatim, B., Ali, M.A.M., Abdullah, M.

ASM Science Journal, 2009;3(2):121-130.

MyJurnal

The paper examines the propagation direction and speed of large scale travelling ionospheric disturbances (LSTIDs) obtained from GPS observations of extreme geomagnetic storms during the 23rd solar cycle; these are the October 2003 and November 2003 geomagnetic storms. In the analysis, the time delay between total electron content (TEC) structures at Scott Base station (SBA) (Lat. –77.85º, Long. 166.76º), McMurdo (McM4), (Lat. –77.84º, Long. 166.95º), Davis (DAV1), (Lat. –68.58º, Long. 77.97º) and Casey station (CAS1) (Lat. –66.28º, Long. 110.52º) GPS stations as well as the distance between these stations were employed in the analysis. The measurements during the October 2003 storm showed obvious time delay between the TEC enhancement occurrences at SBA/MCM4, DAV1 and CAS1 stations. The time delay indicated a movement of the ionospheric structures from higher to lower latitudes in a velocity ranging between 0.8 km/s – 1.2 km/s. The first sudden TEC enhancement was observed at SBA/McM4 (Lat. –75.84º) followed by CAS1 station (Lat. –66.28º) and the final TEC enhancement was seen at DAV1 station (Lat. –68.58º) with TEC magnitude decreasing while moving from higher to lower latitudes. One important observation was that although the latitude of the CAS1 station was lower than the DAV1 station, the TEC enhancement was firstly seen at the CAS1 station due to the shorter distance between SBA and CAS1 compared with the distance between SBA and CAS1 of about 500 km. The TEC measurements during the November 2003 storm showed an opposite propagation direction (i.e. poleward direction from lower to higher latitudes) which was seen with a velocity ranging between 0.3 km/s – 0.4 km/s. As similar response was observed using vertical TEC measurements obtained from individual PRN satellites but with higher velocity ranges (1.2 km/s – 2.4 km/s during October
and 0.5 km/s – 0.7 km/s during November). The equatorward or poleward expansion of LSTIDs during the October and November 2003 storms was probably caused by the disturbances in the neutral temperature which occurred close to the dayside convection throat or due to the neutral wind oscillation induced by atmospheric gravity waves launched from the aurora region.

Experimental study on permeability stress sensitivity in tight sandstone oil reservoirs

Xiaofeng Tian, Linsong Cheng, Wenqi Zhao, Yiqun Yan, Xiaohui He, Qiang Guo

Sains Malaysiana, 2015;44:719-725.

In this paper, seven permeability stress sensitivity experiments were conducted to show the features of permeability stress
sensitivity. The cores in the experiments were taken from the tight sandstone oil reservoir in Ordos Basin. Then advanced
technologies, such as casting thin section, scanning electron microscope and rate-controlled mercury penetration, were
applied to explain the mechanism of permeability stress sensitivity in tight oil reservoirs. The results indicated that
the permeability reduction and recovery in gas permeability stress sensitivity increases as the permeability decreases.
This was resulted from the maximal throat radius. The permeability reduction in liquid permeability stress sensitivity
increases at first and then decreases as the permeability decreases. The permeability recovery decreases to zero as the
permeability decreases. Additionally, the differences between gas and liquid permeability stress sensitivity become greater
as the permeability decreases. These were resulted from the effect of the critical throat radius. This paper corrects the
mistakes about the stress sensitivity in tight oil reservoirs from gas permeability stress sensitivity experiments which is
significant to the development of tight sandstone oil reservoirs.

Three-Dimensional Pharyngeal Airway Changes After 2-Jaw Orthognathic Surgery With Segmentation in Dento-Skeletal Class III Patients

Tan SK, Tang ATH, Leung WK, Zwahlen RA

J Craniofac Surg, 2019 Mar 28.

PMID: 30946225 DOI: 10.1097/SCS.0000000000005351

PURPOSE: To investigate short- and long-term three-dimensional changes of pharyngeal airway morphology and hyoid bone position in dento-skeletal class III deformity patients after 2-jaw orthognathic surgery with segmentation.

METHODS: A retrospective analysis has been performed on patients with dento-skeletal class III deformity who had undergone orthognathic 2-jaw surgery with segmentations, presenting both pre- and post-surgical cone-beam computed tomographys. Three-dimensional skeletal movements, pharyngeal airway changes and hyoid bone position were measured and correlated.

RESULTS: The mean short term postsurgical review period for all included 47 patients was 5.8 ± 2.2 months. Thirteen patients among them provided a mean long term period of 26.4 ± 3.4 months. The mean postsurgical maxillary movement was 2.29 ± 2.49 mm in vertical, 2.02 ± 3.45 mm in horizontal direction, respectively, while the mandibular movement was 6.49 ± 4.58 mm in vertical, and -5.85 ± 6.13 mm in horizontal direction. In short-term, the vertical length of nasopharynx was found to be reduced (P = 0.005) but increased for the oropharynx (P 0.05) detected between patients with and without genioplasty advancement.

CONCLUSION: Two-jaw orthognathic surgery in dento-skeletal class III patients led to a statistically non-significant reduction of the post-surgical airway volume in both short- and long-term. Although the post-surgical oropharyneal minimum cross-sectional area was decreased significantly in the short term, this finding did not persist in the long term.

PMID: 34400422 DOI: 10.1136/bcr-2021-242122

Foreign body (FB) in the external auditory canal is more common among the paediatric age group compared with adult patients and it may be deposited in various ways. An accidental animate aural FB is reported to be commonly encountered in adults whereas inanimate FBs are likely to be found among adult patients with learning disability. An elderly man presented with accidental penetration of rattan tree stem into his ear while gardening. Removal of a FB from the external auditory canal requires expertise as deep penetration of a FB into the middle and inner ear may lead grave complications, especially when overzealous removal is attempted by nonear, nose and throat (ENT) personnel. This case emphasises on the importance of awareness of meticulous removal of a FB under proper visualisation so as to avoid unnecessary complications. Additionally, we propose an algorithm for proper removal of aural FB in an acute care setting.

PMID: 22582543

OBJECTIVE: Ear, nose and throat foreign bodies are common in ENT clinical practice. This study was designed to establish the local data of otorhinolaryngeal foreign bodies in term of prevalence among paediatric and adult groups, the clinical features, types of foreign body at different sites, and laterality of foreign bodies.
METHOD: This study was carried out at ENT department, Sarawak General Hospital, Malaysia, from 1st January 2005 to 31st December 2009. A total of 1084 cases were included and statistically analyzed.
RESULT: Ear foreign bodies showed the highest incidence which was consisted of 480 (44.3%) cases, followed by nose in 270 (24.9%) cases, pharynx in 251 (23.2%) cases, esophagus in 57 (5.3%) cases and laryngo-tracheobronchial tree in 26 (2.4%) cases. Otorhinolaryngeal foreign bodies occurred more frequently in 0-10 year old age group which constituted 651 (60.1%) cases. The descending order of frequency for foreign body sites in adult was pharynx (17.2%), ear (12.8%), esophagus (3.1%), nose (1.7%) and laryngo-tracheobronchial tree (1.1%). The type of foreign bodies varies with age group and site of foreign body lodgement. In general, common foreign bodies in both adult and children were food related, with the additional of small objects such as plastic toy in paediatric group.
CONCLUSION: Otorhinolaryngeal foreign bodies were found more frequently in children. The types of foreign body were different from age group and sites of foreign body lodgement. The local food constituted the highest incidence of ear, nose, and throat foreign bodies with additional of plastic toys in paediatric group.

To review the long term outcome of Uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnoea syndrome in a tertiary referral centre. 38 records were traced where UPPP was done from July 2000 to December 2007. 14 patients were followed up for one to seven years where the Epworth sleepiness scale was scored, long term side effects documented and post operative muller's manoeuvre done. Success of UPPP is defined as a reduction in apnoea hypopnea index (AHI) more than 50%. Sixty percent (60%) were successfully treated with UPPP in the long term. Mean ESS was significantly reduced from 12 +/- 6 to 7 +/- 4. 11 out of 14 patients (78.5%) were reported to develop long term side effects of UPPP, the highest being velopharyngeal insufficiency (42.8%). In conclusion, UPPP is effective in improving symptoms of OSA in the long term. However, in view of its side effects, uvula preserving surgery should be considered as a surgical option.

Significance of enteric gram-negative bacilli in the throat

Philpot CR, McDonald PJ, Chai KH

J Hyg (Lond), 1980 Oct;85(2):205-10.

PMID: 7005325

Pharyngeal micro-organisms of 131 Australian and Malaysian children and adults were compared by analysis of aerobic culture of throat swab specimens. Enteric Gram-negative bacilli were commonly isolated in small numbers from Malaysian adults whether they had sore throats (28%) or not (36%), but were detected in only 9% of Australian adults without sore throats and in only 12% and 4% of Malaysian children with and without sore throats respectively. In other respects microbiological findings were similar in the different groups of subjects studied. It is concluded that the pharyngeal carriage rate of enteric Gram-negative bacilli may differ substantially between different groups of normal individuals. Our findings also suggest that these micro-organisms do not have a pathogenic role in pharyngitis.

PMID: 32692651 DOI: 10.1016/j.tube.2020.101965

The purpose of this study was to investigate the composition of throat microbiota in pulmonary tuberculosis patients (PTB) in comparison to healthy tuberculin skin test positive (TSTp) and negative (TSTn) individuals. Throat swabs samples were collected, and the microbiota was characterized. Richer operational taxonomic units (OTUs) were present in PTB group, compared to TSTp and TSTn. Regarding alpha diversity analysis there was a higher community diversity in TSTn compared to TSTp. Beta diversity analysis showed different species composition in TSTp compared to TSTn and PTB. There was higher presence of Firmicutes in PTB and TSTn compared to TSTp group at phylum level. At the genus level, Leuconostoc and Enterococcus were higher in TSTn compared to TSTp and Pediococcus, Chryseobacterium, Bifidobacterium, Butyrivibrio, and Bulleidia were higher in PTB compared to TSTn. Streptococcus was higher in TSTn compared to PTB and Lactobacillus in PTB compared to TSTp. At species level, Streptococcus sobrinus and Bulleidia moorei were higher in PTB compared to TSTn individuals, while Lactobacillus salivarius was higher in PTB compared to TSTp. The differences in the microbiome composition could influence the resistance/susceptibility to Mtb infection.

Enterotoxin production by Staphylococcus aureus strains isolated from humans, foods and animals in Malaysia

Lim YS, Jegathesan M, Koay AS

Southeast Asian J Trop Med Public Health, 1982 Mar;13(1):133-7.

PMID: 7112212

Enterotoxin production by strains of Staphylococcus aureus isolated from human, food and animal sources was investigated. Of the 130 isolates studied, 27 (20.8%) were found to be enterotoxigenic. The most common enterotoxin detected from human sources was enterotoxin C whereas enterotoxin B occurred more frequently in staphylococcal strains of food origin. The 2 enterotoxigenic strains, from animals isolated from a dog and a goat, produced enterotoxins A and C, respectively. Enterotoxin E was not detected alone from any of the enterotoxigenic strains studied, but occurred together with other enterotoxins. The need to detect enterotoxin in staphylococcal strains and in suspected foods for the confirmation of staphylococcal food poisoning is discussed.
