Pregnancy outcome and cord blood cotinine level: A cross-sectional comparative study between secondhand smokers and non-secondhand smokers

OBJECTIVE

To compare the pregnancy outcome and cord blood cotinine levels between secondhand smokers and non-secondhand smokers.

STUDY DESIGN

This was a cross-sectional comparative study in a Malaysian tertiary obstetric hospital involving 200 non-smoking pregnant women at term, of whom 100 were secondhand smokers and 100 were non-secondhand smokers. Those with multiple pregnancies, with a body mass index (BMI) of more than 30kg/m² or who delivered by Caesarean section were excluded. The participants' basic demographic details, delivery details, neonatal outcome and placental weight were recorded. Umbilical cord blood samples were obtained, and cord blood cotinine levels were measured with a Cotinine ELISA kit. The primary outcomes were baby's birth weight, length, and head circumference, Apgar score at 5min and placental weight. The secondary outcome was difference in cord blood cotinine levels between the two groups and the correlation of these differences with the neonatal outcome.

RESULTS

The secondhand smoker group had significantly lower baby weight (2.94±0.31kg vs 3.05±0.40kg), head circumference (30.87±2.35cm vs 37.13±2.36cm), length (46.58±1.95cm vs 51.53±2.05cm) and placental weight (520±73.5g vs 596±61.3g) and significantly higher cord blood cotinine levels (16.35±12.84ng/mL vs 0.56±0.22ng/mL). Cord blood cotinine levels had significant negative correlations with placental weight (r=-0.461), baby's weight (r=-0.297), baby's head circumference (r=-0.501) and baby's length (r=-0.374).

CONCLUSION

Secondhand smoke increases the incidence of adverse pregnancy outcomes (newborns'anthropometric measurements and placental weight) and causes higher cord blood cotinine levels.

Prevalence of menopausal symptoms, its effect to quality of life among Malaysian women and their treatment seeking behaviour

INTRODUCTION

This study aimed to determine the prevalence of menopausal symptoms, its effect to the quality of life and their treatment seeking behaviour in a multiracial community in Malaysia.

METHODS

This is a cross-sectional study involving postmenopausal women in Klang Valley, Malaysia. Data was obtained by face-to-face interview using standardised questionnaires on sociodemographic data, Menopause Rating Scale questionnaire, effect to quality of life and treatment sought.

RESULTS

A total of 258 women, including Malays (82%), Indians (14.1%) and Chinese (3.9%) were recruited. The median age was 58 (range 45-86) years old. Joint and muscular discomfort (73.3%) and fatigue (59.3%) were the most prevalent symptoms. Significant association with ethnicity were demonstrated with Malays was found to have 3.1 times higher incidence of sexual problems than Indians, (Odds Ratio (OR) 3.103; 95%CI 1.209, 7.967) and Indian had 2.6 times higher incidence of irritability compared to Malays (OR 2.598; 95%CI 1.126, 5.992). Fifty-two percent of women felt that menopausal symptoms affected their quality of life but there were only 2.7% who were severely affected. There were 24.8% of women who sought treatment and only 20.3% of those who took hormone replacement therapy. There was no significant association found between their treatment seeking behaviour in association with ethnicity, age, parity, marital and occupational status.

CONCLUSION

Menopausal symptoms were prevalent among menopausal women, although only a small group of women who were severely affected. There was a lack of tendency in seeking treatment for menopausal symptoms among the women.

Does 3D produce more symptoms of visually induced motion sickness?

3D stereoscopy technology with high quality images and depth perception provides entertainment to its viewers. However, the technology is not mature yet and sometimes may have adverse effects on viewers. Some viewers have reported discomfort in watching videos with 3D technology. In this research we performed an experiment showing a movie in 2D and 3D environments to participants. Subjective and objective data are recorded and compared in both conditions. Results from subjective reporting shows that Visually Induced Motion Sickness (VIMS) is significantly higher in 3D condition. For objective measurement, ECG data is recorded to find the Heart Rate Variability (HRV), where the LF/HF ratio, which is the index of sympathetic nerve activity, is analyzed to find the changes in the participants' feelings over time. The average scores of nausea, disorientation and total score of SSQ show that there is a significant difference in the 3D condition from 2D. However, LF/HF ratio is not showing significant difference throughout the experiment.

Antrochoanal polyp mimicking juvenile nasoangiofibroma

Antrochoanal polyp is a benign lesion, usually arising from the maxillary sinus extending posteriorly into the nasopharynx. Typically it presents as a unilateral nasal obstruction with mucopus rhinorrhea, sleep disturbance, postnasal drip, and mouth breathers. Epistaxis is an extremely rare complaint. Unilateral nasal mass presenting in a teenage boy will increase the suspicion of juvenile nasoangiofibroma. We report a teenage with extensive unilateral nasal mass with such presentation, which later turned out to be antrochoanal polyp.

Noise-induced hearing loss among quarry workers in a north-eastern state of malaysia: a study on knowledge, attitude and practice

OBJECTIVES

Noise is known to be one of the environmental and occupational hazards listed in the Factory and Machinery Act 1967. Quarries with loud deafening sounds from trucks and machineries pose the risk of noise-induced hearing loss to workers. This study was designed to assess the knowledge, attitude and practice towards noise-induced hearing loss and to determine the prevalence of noise-induced hearing loss and its associated factors among quarry workers in a north-eastern state of Malaysia.

METHODS

A cross-sectional study was conducted at six quarries in a north-eastern state of Malaysia, with 97 consented respondents who answered a validated version of a questionnaire and underwent pure tone audiogram. The respondents were male, aged between 18 to 50 years, working in the quarry area for at least 6-months duration with no family history of ear diseases.

RESULTS

The mean percentage scores of knowledge, attitude and practice were 44 (11), 70 (10) and 28 (16) percent, respectively. The prevalence of noise-induced hearing loss was found to be 57 (95% CI: 47, 67) with 46 (84%) having mild and moderate noise-induced hearing loss, and 34 (62%) involved both ears. Multiple logistic regressions showed that age and practice score were the associated factors with odd ratios of 1.1 (95% CI: 1.1, 1.2; p<0.001) and 0.9 (95% CI: 0.8, 1.0; p=0.008), respectively.

CONCLUSION

The knowledge, attitude and practice scores of the respondents were poor and the high prevalence of noise-induced hearing loss was contributed by factors such as poor practice and old age.

Unusual Airway Foreign Body In An 11-Year-Old Boy

Foreign body in early pediatric life is common, owing to the child’s developing dentition and maturity of swallowing mechanism. As the child grew older, the nature of foreign body inhaled might changed. Most of them are due to carelessness and improper habit of holding foreign material in between the lips. We report a case of a boy who inhaled a soft-board metal pin, which was retrieved after multiple attempts due to the nature of the pin that easily slipped and dislodged into distal bronchioles.

The effect of Tualang honey in enhancing post tonsillectomy healing process. An open labelled prospective clinical trial

INTRODUCTION

Tonsillectomy is a common operative procedure performed for tonsillar hypertrophy complicates with recurrent tonsillitis. Among the post tonsillectomy morbidities, post operative wound healing is of utmost importance to be effectively managed as it will interfere with patient recuperation from surgery. Tualang honey has been shown to accelerate wound healing in postoperative patients.

OBJECTIVE

The aim of this study was to investigate the effect of Tualang honey in enhancing healing process in post tonsillectomy patients.

METHODOLOGY

In this open labelled prospective study, the selected paediatric patients were randomized into two groups. The 35 subjects in the Tualang honey-antibiotic group received 3 mls of Tualang honey intraoperatively followed by 4 mls of oral Tualang honey three times daily for seven days. Concurrently, 25mg/kg of intravenous Sultamicillin was given three times daily for two days followed by oral Sultamicillin twice daily for five days. The 28 subjects in the antibiotic only group received intravenous at 25mg/kg Sultamicillin kg for two days followed by oral Sultamicillin twice daily for five days. The healing process was assessed at day 1, day 3, day 7 and day 14 postoperatively by semiquantitative endoscopic photograph examination of both tonsillar fossae.

RESULTS

The average ages for the treatment group and the control groups were 9 and 11 years old respectively. Wound healing was significantly faster in the treatment group in both tonsillar fossae compared to the control group (left: p-value = <0.001; right: p-value = <0.001).

CONCLUSION

Tualang honey has positive effect in enhancing healing process in post tonsillectomy patient. It is easy to use topically, safe to consume orally and available at low cost locally. Overall it can be used as an excellent adjunct therapy for post operative patients.

Co-existing of sinonasal inverted papilloma and angiofibroma: case report and review of the literature

Sinonasal tumors may grow to considerable size before presentation and in view of their relation to the base of skull, orbit, cranial nerves and vital vessels; a precise diagnostic and therapeutic planning is needed to achieve the optimal results. We report a case who presented with unilateral nasal blockage, rhinorrhea and episodes of epistaxis which diagnosed as sinonasal inverted papilloma and angiofibroma.

Cystic hygroma co-existing with congenital subglottic stenosis

Respiratory distress is one of the commonest cause of admission into a Neonatal Intensive Care Unit, be it surgical or medical in nature. Adequate and prompt resuscitation as well as intubation can be life saving. Emergency or early tracheostomy may be necessary if airway intervention is needed. The authors present the case of a term neonate who was born with a large cervical cystic hygroma causing compression of the airway, together with a concurrent grade III subglottic stenosis, in respiratory distress within few minutes of life. Nine months post tracheostomy and sclero-therapy treatment twice, the child shows marked improvement. The succesful management of this unusual case of severe extrinsic compression with concurrent internal airway obstruction is presented.

Solitary posterior triangle neck mass as the rare sole presentation of papillary thyroid carcinoma

Introduction: Papillary thyroid carcinoma is the most common differentiated thyroid malignancy. It offers good prognosis and the presentation is usually consistent with an enlarged thyroid, mostly solitary nodule which biochemically euthyroid and radiologically normal appearance. On rare occasions, the thyroid gland enlargement can present together with multiple neck lymphadenopathy.Case report: We report a case of middle aged man presented with a posterior neck mass without any other symptom. Histopathology report of the excised mass confirmed the diagnosis of, papillary thyroid carcinoma which warranted total thyroidectomy and neck dissection.  DOI: http://dx.doi.org/10.3329/bjo.v18i1.10427 Bangladesh J Otorhinolaryngol 2012; 18(1): 87-90

Cryptococcocis: a rare fungal infection of the tongue

Fungal infection in the oral cavity is not uncommon. The site involved is usually species related. Cryptococcus rarely infects the oral cavity. We report an elderly patient who presented with a central lesion on the dorsum of the tongue. Biopsy revealed a fungal infection. Special stains confirmed cryptococcus. Being a rare location for cryptococcal infection, clinical suspicion should be correlated with histopathological examination. Once confirmed, the patient should be treated with an antifungal medication.

A clinical audit programme for diagnostic radiology: the approach adopted by the International Atomic Energy Agency

The International Atomic Energy Agency (IAEA) has a mandate to assist member states in areas of human health and particularly in the use of radiation for diagnosis and treatment. Clinical audit is seen as an essential tool to assist in assuring the quality of radiation medicine, particularly in the instance of multidisciplinary audit of diagnostic radiology. Consequently, an external clinical audit programme has been developed by the IAEA to examine the structure and processes existent at a clinical site, with the basic objectives of: (1) improvement in the quality of patient care; (2) promotion of the effective use of resources; (3) enhancement of the provision and organisation of clinical services; (4) further professional education and training. These objectives apply in four general areas of service delivery, namely quality management and infrastructure, patient procedures, technical procedures and education, training and research. In the IAEA approach, the audit process is initiated by a request from the centre seeking the audit. A three-member team, comprising a radiologist, medical physicist and radiographer, subsequently undertakes a 5-d audit visit to the clinical site to perform the audit and write the formal audit report. Preparation for the audit visit is crucial and involves the local clinical centre completing a form, which provides the audit team with information on the clinical centre. While all main aspects of clinical structure and process are examined, particular attention is paid to radiation-related activities as described in the relevant documents such as the IAEA Basic Safety Standards, the Code of Practice for Dosimetry in Diagnostic Radiology and related equipment and quality assurance documentation. It should be stressed, however, that the clinical audit does not have any regulatory function. The main purpose of the IAEA approach to clinical audit is one of promoting quality improvement and learning. This paper describes the background to the clinical audit programme and the IAEA clinical audit protocol.

Identification of Entamoeba histolytica trophozoites in fresh stool sample: comparison of three staining techniques and study on the viability period of the trophozoites

Entamoeba histolytica causes about 50 million infections worldwide with a death rate of over 100,000 annually. In endemic developing countries where resources are limited, microscopic examinations based on Wheatley trichrome staining is commonly used for diagnosis of intestinal amoebiasis. Other than being a time-consuming method, it must be performed promptly after stool collection as trophozoites disintegrate rapidly in faeces. The aim of this study was to compare the efficacies of Eosin-Y, Wheatley trichrome and Iodine stains in delineating the diagnostic features of the parasite, and subsequently to determine the suitable microscopy observation period for detection of erythrophagocytic and non-erythrophagocytic trophozoites spiked in semi-solid stool sample. Wheatley trichrome staining technique was performed using the standard method while the other two techniques were performed on the slides by mixing the respective staining solution with the spiked stool sample. One million of axenically cultured non-erythrophagocytic E. histolytica and erythrophagocytic E. histolytica were separately spiked into 2 g of fresh semisolid faeces. Percentage viability of the trophozoites in the spiked stool sample was determined at 30 minute intervals for eight hours using the 0.4% Trypan blue exclusion method. The results showed that Eosin-Y and Wheatley trichrome stained the karyosome and chromatin granules better as compared to Iodine stain. The percentage viability of non-erythrophagocytic trophozoites decreased faster than the erythrophagocytic form in the first 5 hours and both dropped to ~10% in the 6th hour spiked sample. In conclusion, Eosin-Y staining technique was found to be the easiest to perform, most rapid and as accurate as the commonly used Wheatley trichrome technique; Eosin-Y stained slide sealed with DPX could also be kept as a permanent record. A period not exceeding 6 hours after stool collection was found to be the most suitable in order to obtain good microscopy results of viable trophozoites.

Challenges in the management of nasopharyngeal carcinoma: a review

Nasopharyngeal carcinoma (NPC) is a non-lymphomatous, squamous cell carcinoma that occurs in the epithelial lining of the nasopharynx, an area that shows varying degrees of differentiation. Although relatively rare worldwide, NPC has substantial incidence and mortality in populations in Southeast Asia and in people with Southern Chinese ancestry. In Malaysia, NPC is a leading cancer type. In the clinic, NPC presents on a very wide spectrum. Therefore, a high degree of suspicion on the part of the clinician and an increased awareness by the patient is essential for the recognition of an early lesion. Early detection of the cancer is important as it affects the patient's prognosis and the mode of treatment. Managing patients with NPC is very challenging as patients usually present late when the cancer is already in an advanced stage. Here, we review the challenges in the management of NPC.

Outcome of Laser-Assisted Uvulopalatoplasty (LAUP) in the Management of Snoring in Hospital Universiti Sains Malaysia (USM)

To determine the outcome of laser-assisted uvulopalatoplasty for the management of patients with snoring in Universiti Sains Malaysia Hospital (HUSM). A retrospective review of patients who underwent LAUP with or without tonsillectomy or adenoidectomy under general anaesthesia between December 2003 to December 2006. Data was obtained from admission and follow-up records in the otorhinolaryngology clinic of USM Hospital (HUSM). A total of nineteen patients underwent procedure for the treatment of snoring. Majority of these patients presented with symptoms of loud snoring and daytime somnolence. The main operations performed were LAUP with or without tonsillectomy or adenoidectomy. The justification for LAUP were overhanging and excessive uvula or soft palate, whereas for adenotonsillectomy were the hypertrophied adenoids and tonsils. On follow-up, most of the patients claimed improvement of snoring within the first 2 months post-operation. However, majority of them defaulted follow-up after that. One patient (AHI preoperatively was mild) was reviewed up to 8 months with no snoring. One patient (AHI was severe preoperatively and normal post operatively) remained in our follow-up was satisfied with the operation. Two patients continued to experience snoring post LAUP despite trial of non-surgical methods. The outcome of LAUP in our patients showed variable results. This showed that patient selection is very important to achieve good result in LAUP. Long-term follow-up is also essential to document the success for LAUP.

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

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.

Adenoid mast cells and their role in the pathogenesis of otitis media with effusion

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.

Appraisal of clinical profile and management of juvenile nasopharyngeal angiofibroma in malaysia

Juvenile nasopharyngeal angiofibroma (JNA) is a benign but locally invasive tumour. Patients are usually in their adolescent age and present with epistaxis and nasal blockage. Diagnosis is based on clinical evaluation and the C.T. scan findings. Pre-operative superselective embolisation (SSE) and surgical excision is the treatment of choice. The out patient clinic of ORL-HNS hospital of University Science Malaysia received 25 referrals, all male, majority between 9-13 years of age and few adolescents. Clinically the patients were consistent with symptoms of recurrent epistaxis and nasal blockage. They reported from October 1998 to October 2001 from with in the state of Kelantan and the nearby states of Pahang, Kedah and Terenganu. Diagnosis was mostly made on typical radiological findings and the tumours were classified accordingly into four stages. SSE and surgical excision was carried out in all cases. Regular follow-up helped us to identify early recurrences which were treated with salvage surgery or radiotherapy in one case with extensive intracranial extension. A retrospective review of presenting features, diagnostic difficulties, surgical approaches and its outcome is presented. Maxillary swing procedure performed in three cases as a new surgical option in the management of JNA is also discussed.
