Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissue that most commonly affects the feet and lower limbs. It is rare for this infection to occur on the face, and it is exceptionally rare for it to involve the nose and sinuses. This paper reports a rare case of nasal chromoblastomycosis in a 50-year-old Malaysian male.

PMID: 8869610

We reviewed the clinicopathological characteristics of 13 cases of calcifying epithelial odontogenic tumour (CEOT) (Pindborg tumour) diagnosed in the Division on Stomatology, Institute for Medical Research, Kuala Lumpur, over a 29-year period. There were eight female and five male patients. These consisted of eight (61.5 per cent) Malays, three (23.1 per cent) Chinese, one (7.7 per cent) Indian and one (7.7 per cent) Melanau. Their ages at presentation ranged from 19-61 years (mean age, 31.8 years). There were 12 central and one peripheral CEOT. Of these, 76.9 per cent of cases were located in the maxilla, the remaining in the mandible. The commonest clinical diagnosis was a dentigerous cyst (66.7 per cent). Enucleation was the main mode of treatment. Histologically, sheets and strands of polyhedral epithelial cells containing eosinophilic, homogeneous globules with Liesegang rings were observed. One case also showed extensive calcification and clear cell differentiation. Immunohistochemistry revealed a variable keratin staining of the CEOT epithelium, confirming its heterogeneity.

A seven-year retrospective analysis of the clinicopathological and mycological manifestations of fungal rhinosinusitis in a single-centre tropical climate hospital

Goh LC, Shakri ED, Ong HY, Mustakim S, Shaariyah MM, Ng WSJ, et al.

J Laryngol Otol, 2017 Sep;131(9):813-816.

PMID: 28841131 DOI: 10.1017/S0022215117001505

OBJECTIVE: To evaluate the clinicopathological and mycological manifestations of fungal rhinosinusitis occurring in the Tengku Ampuan Rahimah Hospital, in Klang, Malaysia, which has a tropical climate.

METHODS: Records of patients treated from 2009 to 2016 were analysed retrospectively. Data from the records were indexed based on age, gender, clinical presentations, symptom duration, clinical signs and mycological growth.

RESULTS: Of 80 samples, 27 (33.75 per cent) had fungal growth. Sixteen patients were classified as having non-invasive fungal rhinosinusitis and 11 as having invasive fungal rhinosinusitis. The commonest clinical presentation was nasal polyposis in non-invasive fungal rhinosinusitis patients (p < 0.05) and ocular symptoms in invasive fungal rhinosinusitis patients (p < 0.05). The commonest organism was aspergillus sp. (p < 0.05) in non-invasive fungal rhinosinusitis and mucorales in invasive fungal rhinosinusitis.

CONCLUSION: There is an almost equal distribution of both invasive and non-invasive fungal rhinosinusitis, as seen in some Asian countries. Invasive fungal rhinosinusitis, while slightly uncommon when compared to non-invasive fungal rhinosinusitis, is potentially life threatening, and may require early and extensive surgical debridement. The clinical presentation of nasal polyposis was often associated with non-invasive fungal rhinosinusitis, whereas ocular symptoms were more likely to be associated with invasive fungal rhinosinusitis.

Suzina AH, Hamzah M, Samsudin AR

J Laryngol Otol, 2003 Aug;117(8):605-8.

PMID: 12956913

The differences in facial anatomical structures of the major ethnic groups, may also be reflected in nasal resistance. Active anterior rhinomanometry (AAR) is the recommended technique for the objective assessment of nasal airway resistance (NAR). This study comprised of 85 adult Malay subjects. All the subjects had to undergo a primary assessment of relevant symptoms of nasal disease and nasal examination before undergoing AAR assessment. The mean value of total nasal airway resistance (NAR) was 0.19 Pa/cm(3)/s (ranged from 0.09 to 0.55 Pa/cm(3)/s) at 75 Pa pressure point and 0.24 Pa/cm(3)/s (ranged from 0.12 to 0.52 Pa/cm(3)/s) at 150 Pa pressure point. The mean unilateral NAR was 0.46 Pa/cm(3)/s at a reference pressure of 75 Pa and 0.51 Pa/cm(3)/s at a reference pressure of 150 Pa. In this study we presented normal values for NAR in healthy Malay adult subjects. AAR proves to be a valuable clinical method for recording and quantitating nasal resistance.

Abdullah B, Hassan S, Sidek D, Jaafar H

J Laryngol Otol, 2006 Jul;120(7):556-60.

PMID: 16834804 DOI: 10.1017/S002221510

INTRODUCTION: Otitis media with effusion (OME) is an inflammation of the middle ear in which a collection of liquid is present in the middle-ear space while the tympanic membrane is intact. The association between adenoid inflammation and OME has long been noted but the exact mechanism is still much debated. We studied the role of adenoid mast cells in the causation of OME.
OBJECTIVE: To study the distribution and role of adenoid mast cells in the causation of OME.
METHODOLOGY: A cross-sectional, prospective study was carried out in the otorhinolaryngologic clinic, department of otorhinolaryngology (ORL), Science University of Malaysia, from June 1999 to September 2001. A total number of 50 cases were studied. Twenty-five of these patients underwent adenoidectomy, while another 25 patients underwent adenoidectomy and myringotomy with ventilation tube insertion. The adenoid specimens from all patients were examined for the number of adenoid mast cells present, using light microscopy and toluidine blue as the staining agent. The results were analysed using SPSS version 10.0 computer software.
RESULT: The population of adenoid mast cells in children with OME was significantly greater than that in children without OME (p=0.000).
CONCLUSION: The increased number of adenoid mast cells in patients with OME suggests that inflammation may play a role in this condition.

A case is described of ameloblastoma of the mandible presenting with multiple recurrences and subsequent extension to the maxilla with resultant transformation into an aggressive (malignant?) epithelial odontogenic ghost cell tumour. The latter is a rare, biologically virulent entity that affects mainly males, exhibits a preference for the maxilla and is histologically characterized by atypical malignant odontogenic epithelium associated with areas of ghost cell formation and varying amounts of dentinoid.

An improved instrument mounting arm

Gendeh BS, Khalid BA, Alberti PW

J Laryngol Otol, 2001 Feb;115(2):126-7.

PMID: 11320829

Although some form of commercial instrument mounting arm is available, a paucity of information in the literature may cause problems in selecting the most appropriate model for an ENT department wishing to trial their invention for use in the clinic or operating theatre. The instrument mounting arm described here is based on existing designs used by hobbyists and model makers for many years but the main benefit of this innovation is its multi-purpose use in the operating theatre and cost effectiveness since it is made of aluminum alloy. It is compact, stable and easily adjustable and can incorporate an endoscope holder or an operating end piece to mount various ENT instruments that offers considerable advantages to the unassisted operator.

Auricular pseudocyst in the tropics: a multi-racial Singapore experience

Tan BY, Hsu PP

J Laryngol Otol, 2004 Mar;118(3):185-8.

PMID: 15068513

Endochondral pseudocyst of the auricle is an uncommon condition that affects predominantly Chinese males, with many reports studying this condition in homogenous Chinese populations. There have been few large-scale reports describing the features of this disease among the other Asian groups. In one of the largest series described to date, we report the epidemiological features, clinico-pathologic characteristics, and success of surgical treatment in 40 patients of different Asian groups presenting with pseudocyst of the auricle. Results showed a Chinese predominance (90 per cent), followed by Malays (five per cent) and Eurasians (five per cent). All had unilateral presentations apart from one patient. Most (55 per cent) presented within two weeks of auricular swelling. Few (10 per cent) had a history of trauma. The pseudocysts predominantly affected the concha (61 per cent). Surgery comprised excision of the anterior wall followed by local pressure application. Only 2.5 per cent had recurrence after surgery. These findings confirm earlier understood features of this disease while revealing some notable variations.

Gendeh BS, Dhillon MK, Hamzah M

J Laryngol Otol, 1994 Mar;108(3):256-60.

PMID: 8169515

Internal jugular vein ectasia is a venous anomaly commonly presenting as a unilateral neck swelling in children and adults. Literature reports of bilateral presentation are rare. Bilateral Doppler ultrasonography is the diagnostic investigation of choice. The possible pathology, aetiology and management are discussed. Conservative management of bilateral cases is recommended in uncomplicated cases.

Bonebridge transcutaneous bone conduction implant in children with congenital aural atresia: surgical and audiological outcomes

Ngui LX, Tang IP

J Laryngol Otol, 2018 Aug;132(8):693-697.

PMID: 30008276 DOI: 10.1017/S0022215118001123

OBJECTIVES: To investigate the surgical and audiological outcomes of the Bonebridge transcutaneous bone conduction hearing implant among children with congenital aural atresia.

METHODS: Six children were recruited and underwent Bonebridge transcutaneous bone conduction implant surgery. The patients' audiometric thresholds for air conduction, bone conduction and sound-field tests were assessed pre-operatively and at six months post-operatively. Patients' satisfaction was assessed at six months post-operatively with the Hearing Device Satisfaction Scale.

RESULTS: No major complications were reported. Mean aided sound-field thresholds improved post-operatively by more than 30 dB for 0.5-4 kHz (p 0.05). All patients were satisfied (scores were over 90 per cent) with the implant in terms of functional outcome and cosmetic appearance.

CONCLUSION: Bonebridge transcutaneous bone conduction implant surgery is safe and effective among children with congenital aural atresia with conductive hearing loss.

Brain waves spectral analysis of human responses to odorous and non-odorous substances: a preliminary study

Chow XH, Ting CM, Wan Hamizan AK, Zahedi FD, Tan HJ, Remli R, et al.

J Laryngol Otol, 2024 Mar;138(3):301-309.

PMID: 37259908 DOI: 10.1017/S0022215123000919

OBJECTIVE: The aim of this study was to identify the potential electrophysiological biomarkers of human responses by comparing the electroencephalogram brain wave changes towards lavender versus normal saline in a healthy human population.

METHOD: This study included a total of 44 participants without subjective olfactory disturbances. Lavender and normal saline were used as the olfactory stimulant and control. Electroencephalogram was recorded and power spectra were analysed by the spectral analysis for each alpha, beta, delta, theta and gamma bandwidth frequency upon exposure to lavender and normal saline independently.

RESULTS: The oscillatory brain activities in response to the olfactory stimulant indicated that the lavender smell decreased the beta activity in the left frontal (F7 electrode) and central region (C3 electrode) with a reduction in the gamma activity in the right parietal region (P4 electrode) (p < 0.05).

CONCLUSION: Olfactory stimulants result in changes of electrical brain activities in different brain regions, as evidenced by the topographical brain map and spectra analysis of each brain wave.

Carbon dioxide laser stomaplasty for tracheostomal stenosis

Sani A

J Laryngol Otol, 1998 May;112(5):467-8.

PMID: 9747477

A method of treating tracheostomal stenosis post-laryngectomy is described. The carbon dioxide (CO2) laser is used to fashion and ablate two triangular areas lateral to the stenosed stoma to provide an immediate enlarged stoma for comfortable breathing. This simple procedure is done under local anaesthesia, is almost bloodless, safe and takes just 10 minutes. Over the last five years eight patients underwent this procedure and seven had a satisfactory stoma without the need to use a tracheostomy tube.
