OBJECTIVE: To assess the cost-effectiveness of introducing pneumococcal polysaccharide and nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) in the National Immunization Programme of Malaysia. This study compared introducing PHiD-CV (10 valent vaccine) with current no vaccination, as well as against the alternative 13-valent pneumococcal conjugate vaccine (PCV13).

METHODS: A lifetime Markov cohort model was adapted using national estimates of disease burden, outcomes of pneumococcal disease, and treatment costs of disease manifestations including pneumonia, acute otitis media, septicemia, and meningitis for a hypothetical birth cohort of 550,000 infants. Clinical information was obtained by review of medical records from four public hospitals in Malaysia from the year 2008 to 2009. Inpatient cost from the four study hospitals was obtained from a diagnostic-related group-based costing system. Outpatient cost was estimated using clinical pathways developed by an expert panel. The perspective assessed was that of the Ministry of Health, Malaysia.

RESULTS: The estimated disease incidence was 1.2, 3.7, 70, and 6.9 per 100,000 population for meningitis, bacteremia, pneumonia, and acute otitis media, respectively. The Markov model predicted medical costs of Malaysian ringgit (RM) 4.86 billion (US $1.51 billion) in the absence of vaccination. Vaccination with PHiD-CV would be highly cost-effective against no vaccination at RM30,290 (US $7,407) per quality-adjusted life-year gained. On comparing PHiD-CV with PCV13, it was found that PHiD-CV dominates PCV13, with 179 quality-adjusted life-years gained while saving RM35 million (US $10.87 million).

CONCLUSIONS: It is cost-effective to incorporate pneumococcal vaccination in the National Immunization Programme of Malaysia. Our model suggests that PHiD-CV would be more cost saving than PCV13 from the perspective of the Ministry of Health of Malaysia.

The Health Economic Impact of Universal Infant Vaccination with the 10-Valent Pneumococcal Nontypeable Haemophilus influenzae Protein D Conjugate Vaccine as Compared with 13-Valent Pneumococcal Conjugate Vaccine in Hong Kong

Lee KKC, Chia Wu DB, Topachevskyi O, Delgleize E, DeAntonio R

Value Health Reg Issues, 2013 May;2(1):64-74.
PMID: 29702855 DOI: 10.1016/j.vhri.2013.01.012

BACKGROUND: Pneumococcal universal vaccination in Hong Kong was introduced in 2009.
OBJECTIVES: We assessed the health and economic impact of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PCV-10) compared with the current 13-valent pneumococcal conjugate vaccine (PCV-13) recommended for Hong Kong in 2011, providing new elements to be considered by public health authorities in the future decision-making process for pneumococcal vaccines in this country.
METHODS: An analytical model was used to estimate the annual economic and health outcomes of invasive pneumococcal disease (IPD), community-acquired pneumonia, and acute otitis media (AOM), including nontypeable H. influenzae-related AOM, for a birth cohort in Hong Kong from the payer perspective with a 10-year horizon. Clinical impact including morbidity-mortality, quality-adjusted life-years (QALYs), incremental costs, and cost-effectiveness comparing PCV-10 and PCV-13 were estimated. Probabilistic sensitivity analyses by using alternate scenarios were performed.
RESULTS: Model projections indicate that PCV-13 and PCV-10 have approximately equivalent impact on the prevention of deaths caused by IPD and pneumonia. PCV-13 is projected to prevent 6 additional cases of IPD, whereas PCV-10 is projected to prevent 13,229 additional AOM cases and 101 additional QALYs. For the base case, PCV-10 vaccination is estimated to save 44.6 million Hong Kong dollars (34.1 million Hong Kong dollars discounted). Sensitivity analysis indicated that PCV-10 would generate more QALYs and save costs as compared with PCV-13.
CONCLUSIONS: Universal infant vaccination with new available pneumococcal vaccines is expected to generate a significant additional impact on reducing the burden of pneumococcal diseases in Hong Kong. PCV-10 vaccination would be potentially a cost-saving strategy compared with PCV-13 vaccination, generating better cost offsets and higher QALY gains.

PMID: 23749009 MyJurnal

A canal wall down mastoidectomy (CWDM) is an effective technique for eradication of advanced chronic otitis media or cholesteatomas. A retrospective study was conducted at a Malaysian Tertiary Medical Center between June 1996 to December 2003 to evaluate the outcome of Modified Radical Mastoidectomy(MRM), a form of CWDM for patients with chronic active otitis media (OM) with cholesteatoma, chronic mastoiditis or chronic active OM with cholesteatoma and mastoiditis. All new cases of MRM which fulfilled the selection criteria were reviewed. The main outcome measures were the hearing outcome and status of dry ear postoperatively. A total of 84 patients had undergone CWDM. However only 63 patients (26 male, 37 female) were included for analysis. The age of the patients ranged between 5 months to 72 years (mean, 31years). The majority of the patients (86%) were adults and 9 (14%) were children. The ossicular chain was eroded in 91% (57 cases). There were 33 patients (53%) who showed no improvement of Air Bone Gap (ABG) closure while 16 patients (25%) had a post-operative improvement. The presence or absence of stapes suprastructure was found to be the major factor in determining the amount of ABG (Chi squared test, P = 0.025 preoperatively and P = 0.031 postoperatively). A dry ear was achieved in 78% of patients with 3% recurrence rate. In conclusion, the study showed that a proper MRM gave high percentage of dry ear and this procedure did not worsen the hearing.

Fulltext Dural tear post mastoidectomy repaired with Dura Gen

Wong CY, Khairi MD, Mohamed SA, Irfan M

Med J Malaysia, 2010 Dec;65(4):307-8.
PMID: 21901952

Dural exposure may occur during the course of thinning the tegmen tympani and tegmen mastoideum in mastoid procedure. If large area of dura is exposed or lacerated, cerebrospinal fluid and brain herniation may enter the mastoid cavity. We report a case of a patient with injured dura mater and tegmen mastoideum during mastoidectomy for chronic suppurative otitis media with cholesteatoma managed by using DuraGen. The dura mater and tegmen defect healed totally showing the success of the procedure. A collagen matrix like DuraGen is an option for repairing dural tear in mastoid region.

Nurliza I, Lim LH

Med J Malaysia, 2011 Aug;66(3):227-30.
PMID: 22111445 MyJurnal

Otitis media with effusion is one of the most common childhood infections, and grommet insertions are done for chronic otitis media which have failed medical therapy. The aims of this study were 1) to determine the patient profile of children needing grommet insertion and 2) to determine if grommet insertion is safe and effective. A retrospective review of 105 children with myringotomy and grommet insertions for chronic otitis media with effusion between 2006 and 2008 was performed. Seventy two percent of patients were younger than 6 years old. Male to female ratio was 4:3. Twelve percent of patients were syndromic. In children with otitis media with effusion, hearing and academic performance improved after grommet insertion. Allergic rhinitis and cleft palate are risk factors for chronic middle ear effusion.

PMID: 19248706 MyJurnal

Nasopharyngeal carcinoma (NPC) is a rare disease in children. Children with NPC almost always have the undifferentiated variant of the disease, which is associated with advanced locoregional and distant metastasis. We report two cases to illustrate that high index of suspicion is necessary to diagnose NPC in children especially those with atypical presentation of otitis media with effusion (OME).

PMID: 26556123 MyJurnal

Rhabdomyosarcoma is a rare tumour in the middle ear and mastoid cavity in children and the diagnosis is difficult. Repeated histological examination may be essential to confirm the diagnosis. We report a 6 year old boy with a left aural polyp, otorrhoea and facial nerve palsy who was initially thought to have otitis media and mastoiditis. He had polypectomy and the tissue taken for histopathology suggested an inflammatory condition. Subsequently he had mastoidectomy. Tissue taken during mastoidectomy was however reported as rhabdomyosarcoma. The child developed a cerebral abscess and eventually succumbed. A literature review of the disease, radiological findings, immunohistochemical features and treatment options is described.

Fulltext Clinical characteristic of vertigo in children

Rosdan S, Basheer L, Mohd Khairi MD

Med J Malaysia, 2015 Aug;70(4):220-3.
PMID: 26358017 MyJurnal

Objective: To review the clinical characteristic of vertigo in children.
Method: A retrospective observational study was done on children who presented to a specialised vertigo clinic over period of six years. The patients’ case notes were retrieved from the medical record unit and reviewed. All patients were seen by an otologist who thoroughly took down history, completed ear, nose, throat and neurological examination.
Result: Seven different causes were identified in 21 patients (86%) while no diagnosis was reached in three patients (12.5%). The most common cause of giddiness was childhood paroxysmal vertigo (33%) followed by benign paroxysmal positional vertigo (16.6%) and sensorineural hearing loss (12.5%). Other causes include chronic suppurative otitis media and anxiety disorder each accounting for 8.3%, one case of cholesteatoma and another case of ear wax each accounting for 4.1%.
Conclusion: It is not uncommon for the children to be affected by vertigo. Management of vertigo in children should include a detailed history, clinical examination, audiological and neurological evaluation. Imaging should be performed in selected patients. The main cause of vertigo in our series is CPV. The outcome of most of the patients is good.

Fulltext Otitis media with effusion: an update

Pang KP, Ang AHC, Tan HKK

Med J Malaysia, 2002 Sep;57(3):376-82; quiz 383.
PMID: 12440282

Otitis media with effusion (OME) is a very common condition seen in children, and is the commonest cause of hearing loss in an infant. It is also a fairly common condition encountered by the family practitioner, and often the family practitioner is the first doctor the parents bring the child to. Otitis media with effusion is a simple condition but, if left undiagnosed or untreated, can lead to preventable long-term consequences. Hence, a high index of suspicion is necessary, early and accurate diagnosis, prompt treatment, with close follow-up is of essence. The epidemiology, aetiological factors, clinical presentations, diagnosis, various medical and surgical options, cost-effectiveness of therapy and the impact of OME on the child's development are discussed.

Fulltext Incidence and management of middle ear effusion in cleft palate patients

Lokman S, Loh T, Said H, Omar I

Med J Malaysia, 1992 Mar;47(1):51-5.
PMID: 1387450

For a complete overall rehabilitation of cleft palate patients a multi-disciplinary approach should be adopted. Plastic and Head and Neck Surgeons in whom most of the treatment are entrusted should be concerned not only at achieving palatal function and cosmetic acceptability but also the various other problems associated with cleft palate especially hearing loss. In this study, 66 patients with repaired and unrepaired cleft palates were examined for the presence of hearing loss due to middle ear effusion. The incidence of middle ear effusion was high (57.6%). It was also found that only eight of these patients (12.1%) ever complained of hearing loss or any associated symptoms and repair of the cleft palate did not influence the incidence of middle ear effusion. As such, screening should be done in all cleft palates and otolaryngologists should therefore play an important role in the multi-disciplinary team which should comprise the paediatrician, plastic surgeon, speech therapist, orthodontist and dental specialist.

Fulltext Mastoiditis in Kelantan

Elango S, Than T

Med J Malaysia, 1995 Sep;50(3):233-6.
PMID: 8926900

Chronic mastoiditis and subperiosteal abscess are rarely seen nowadays in most countries. Thirty-four cases of mastoiditis were reviewed to find out the prevalence of chronic mastoiditis in the east coast of Malaysia. Twenty (58.82%) of these cases were a sequelae of chronic suppurative otitis media with cholesteatoma. All the patients with chronic mastoiditis were more than six years old. Forty-five percent of cases with chronic mastoiditis had a well pneumatized mastoid air cell on the unaffected side. The occurrence of chronic mastoiditis or cholesteatoma in a well pneumatized mastoid is not really as rare as was thought to be. X-ray of the mastoids is very useful in diagnosing patients with chronic mastoiditis and cholesteatoma. Mastoiditis is uncommon in adults and whenever a case is seen, an underlying pathology like cholesteatoma should be suspected.

Fulltext Reevaluating the use of antibiotics in acute otitis media in children

Elango S

Med J Malaysia, 2003 Aug;58(3):465-9.
PMID: 14750393

Increasing concern about the antibiotic resistance in acute otitis media (AOM) has led to debate over use of antibiotic in AOM and duration of therapy. Many studies have proved that watchful waiting should be used more often for acute otitis media. In children over two years, the most appropriate treatment was found to be initial observation followed by 5 days of an antibiotic if the child failed to improve spontaneously. In children less than 2 years or one with severe symptoms antibiotic can be started after 24 hours if there is no improvement with symptomatic treatment. Physician should be more selective in the prescription of antibiotics early in AOM.

The association of allergy and chronic suppurative otitis media: A study in a tropical country

Mohd Khairi MD, Shahrjerdi B, Ramiza RR, Normastura R

Med J Malaysia, 2019 Jun;74(3):205-208.
PMID: 31256174

OBJECTIVE: Chronic suppurative otitis media (CSOM) usually begins as a spontaneous perforation of tympanic membrane due to an acute infection of the middle ear. This study was aimed to evaluate the association between allergy and CSOM.
METHODS: A case-control study was carried out among patients with CSOM (cases) and controls were those with no ear pathology. The presence of CSOM was made through a medical history and otoscopic examination. Allergen testing was done by the skin prick test.
RESULTS: In all 124 subjects were recruited in this study with equal number of the cases and controls. The commonest positive reaction in the skin prick test in both groups was to house dust mites. Among CSOM cases, half (50%) of them had an allergy to Blomia tropicalis and 48.4% to Dermatophagoides while in the control group, 27.4% to Dermatophagoides and 25.8% to B. tropicalis. There were significant associations between CSOM and allergy to B. tropicalis (p=0.005), Dermatophagoides (p=0.016) and Felis domesticus (p=0.040). The prevalence of allergy at 95% confidence interval (95%CI) in CSOM and control groups were demonstrated as 59.7% (95%CI: 47.5, 71.9) and 30.6 % (95%CI: 19.1, 42.1) respectively. There was a significant association between allergy and CSOM (p=0.001).
CONCLUSION: Indoor allergens are the most prevalent in our environment and therefore good control may difficult to achieve. The hypersensitivity states of the subject are likely to have a role in the pathogenesis of CSOM especially in the tropical countries where allergy occurs perennially.

PMID: 29197892 MyJurnal

A patient presenting with an ear polyp is a common finding in otorhinolaryngology practice. The common causes include chronic otitis media and cholesteatoma. We report an adult female patient with a history of acute leukaemia presenting with chronic otitis media symptoms and right ear polyp. She was subsequently diagnosed as relapse of B-cell acute lymphoblastic leukaemia based on histopathological examination. The presentation may be similar to an inflammatory pathology of the middle ear, making it misleading.

Fulltext Clinical and audiological profiles in children with chronic otitis media with effusion requiring surgical intervention

Abdullah B, Hassan S, Sidek D

Malays J Med Sci, 2007 Jul;14(2):22-7.
PMID: 22993488 MyJurnal

To determine the characteristic presenting symptoms, otoscopic findings, audiological profiles and the intraoperative findings of children with chronic otitis media with effusion who required surgical intervention. A prospective cross sectional study was undertaken in the otorhinolaryngology clinic of USM Hospital (HUSM) involving 25 cases (50 ears) of children with chronic otitis media with effusion requiring surgical intervention from June 1999 to September 2001. Their ages ranged from 3 to 12 years old. The gender distribution included males at 72 % and females at 28 %. The presenting symptoms noted were hearing impairment (52%), otalgia (18%), ear block (16%) and tinnitus (14%). The otoscopic findings were fluid in the middle ear (40%), dullness (32%) and retraction of the tympanic membrane (28%). On audiometry, 24 ears had moderate deafness (48%), 16 ears had mild deafness (32%) while 4 ears had severe deafness (8%). With tympanometry, 42 ears out of the total 50 had a flat type B curve (84%) while 6 ears had type As curve (12%). During myringotomy, middle ear secretion was seen in 38 ears (76%) out of the 50 ears; 22 ears had mucoid secretion while 16 ears had serous secretion. Clinically, the commonest presenting symptom was hearing impairment (52%) while the most common otoscopic finding was fluid in the middle ear (40%). Audiologically, most patients had moderate conductive hearing loss (48%) and a type B curve (84%) on tympanometry. On myringotomy middle ear fluid was found in 76 % of the ears.
