Over a period of recent 12 months, 41 patients who had localized pulmonary lesions, but were not diagnosedpathologically through bronchoscopy, transbronchial biopsy, sputum examination and cervical lymph node biopsy,underwent percutaneous needle aspiration and biopsy with a diagnostic accuracy of 83% concerning malignancy vs.benignity and 78% considering the specific cell types as well. Six patients developed small asymptomaticpneumothorax and the other three develped small amount of hemoptysis; One of them required treatement. There were21 malignancies and 14 benign lesions. Three cases were misinterpreted and five were inconclusive on cytology,maybe due to inadequate material. No material was aspirated in one case due to hardness of the mass, which, later,confirmed chondroarcoma on surgery. The method, problems and complications are discussed. Nowadays, thepercutaneous needle aspiration and biopsy appears to be the procedure of choice in pulmonary coin lesionsespecially when they are smaller, more peripheral, and whenever meastatic neoplasm in suspected.

Two duplex PCR assays were established for the detection of C. trachomatis (Ct), N. gonorrhoeae (GC), M. hominis (Mh), and U. urealyticum (Uu). These assays were used on clinical specimens obtained from women with Premature Rupture of Membrane or Post Partum Fever, from preterm infants, as well as from women with uneventful pregnancies and their babies delivered vaginally at term. The analytical sensitivity of the duplex PCR assays with internal controls incorporated is 7.0, 19.0, 5x10(3) and 7x10(2) genome copies per reaction for Ct, GC, Mh and Uu respectively. Specificity was demonstrated by the amplification of only target DNA in the presence of other organisms. Among 40 women with normal, at term, deliveries, there were 6 positives for Ct, 2 for GC and 1 for Uu. None of these women had signs of genital tract infection. The Mh/Uu PCR was positive in 11 of 40 PROM cases, with 7 women positive for Uu, 2 for Mh and 2 others for both organisms. Of 40 blood cultures taken from post-partum maternal infections, 6 were positive for Ct and 1 for Mh. Respiratory secretions from 30 premature neonates yielded 5 positives for Uu and one each for Mh and Ct. In contrast, there was only 1 positive result (for Mh) in 30 mature neonates. With 1 exception, all mycoplasma and ureaplasma positives were confirmed by culture and the concordance between paired tracheal aspirates and nasopharyngeal swabs from neonates was 96.7%. These results show the potential use of the duplex PCR assays for the diagnosis of maternal and neonatal disease caused by the four urogenital pathogens.

INTRODUCTIONPosterior segment involvement has been described to be associated with central nervous system involvement in sarcoidosis as a result of direct sarcoid tissue infiltration or mass effect of a cerebral lesion. However, isolated intermediate uveitis occurring concurrently with central nervous system involvement prior to extensive systemic disease is rare.

CLINICAL PICTUREWe describe a patient with neuro-ophthalmic manifestations of intermediate uveitis and an enhancing basal ganglia lesion at initial presentation, in the absence of extensive systemic disease.

TREATMENTHe was treated with high-dose systemic steroids which was progressively tailed down over 6 months.

OUTCOMEThere was prompt resolution of vitritis with good preservation of visual acuity.

CONCLUSIONThe difficulties of the initial diagnosis of sarcoidosis and the indications for initiation of steroid therapy are illustrated. We use this case to emphasise the need for a high clinical suspicion of sarcoidosis in the presence of similar unusual and seemingly unrelated combinations of neurological manifestations so as to facilitate the prompt institution of appropriate treatment when indicated.

INTRODUCTIONThis study aims to review the results of hearing screens in newborns with cleft deformities.

MATERIALS AND METHODSA retrospective audit of 123 newborns with cleft deformities, born between 1 April 2002 and 1 December 2008, was conducted. Data on the results of universal newborn hearing screens (UNHS) and high-risk hearing screens, age at diagnosis, severity/type of hearing loss and mode of intervention were obtained from a prospectively maintained hearing database.

RESULTSThirty-one of 123 newborns (25.2%) failed the first automated auditory brainstem response (AABR). Seventy percent of infants (56 out of 80) who passed the UNHS failed the high-risk hearing screens which was conducted at 3 to 6 months of age. Otolaryngology referral rate was 67.5% (83/123); 90.3% of 31 newborns who failed the first AABR eventually required otolaryngology referrals. Incidence of hearing loss was 24.4% (30/123; 25 conductive, 2 mixed and 3 sensorineural), significantly higher than the hospital incidence of 0.3% (OR: 124.9, 95% CI, 81.1 to 192.4, P <0.01). In terms of severity, 8 were mild, 15 moderate, 5 severe, 2 profound. Eighteen out of 30 infants (60%) were detected from the high-risk hearing screens after passing the first AABR.

CONCLUSIONThese newborns had a higher risk of failing the UNHS and high-risk hearing screen. There was a higher incidence of hearing loss which was mainly conductive. Failure of the first AABR was an accurate predictor of an eventual otolaryngology referral, suggesting that a second AABR may be unnecessary. High-risk hearing screens helped to identify hearing loss which might have been missed out early on in life or which might have evolved later in infancy.

Compliance of epileptic patients is one of the most important factors for adequate therapy. Recently, it had been shown that the variability of three serial measurement of the serum levels of antiepileptic drug(AED) may be used as an indication of the degree of compliance. Coefficient variation(CV) of serum drug levels calculated by only one AED had been used to determine the compliance in epileptic patients who took multiple AEDs. We attempted to evaluate the CV of AEDs and then find the objective clue of compliance and the compatible therapeutic planing according to CV. Ninety seven epileptic patients of outpatients department of the Gyengsang National University Hospital were entered to this study. All patients were taking medication at least for 6 months without any changes of drug regimen. Patient's information was acquired by reviewing the chart and interview with questionnaire. With these informations, we determined the compliance of the patients. Antiepileptic serum levels were measured three times at intervals of at least two to four weeks apart, and their CV was calculated. We compared the CV between the compliant and non-compliant group in each AED(phenytoin, carbamazepine , valproic acid) and three drugs in the compliant group. The mean CVs of phenytoin, carbamazepine and valproic acid in the compliant group were 18.3+/-13.0, 15.2+/-10.2 and 23.8+/-8.9, respectively(mean+/-SD). The mean of CV in the compliant and the non-compliant group were 17.9+/-10.9 and 38.8+/-27.2, respectively. The CVs of the compliant group were significantly lower than those of the non-compliant group(p<0.05). However, CVs had no significant difference between three antiepileptic drugs. This study showed that CVs of AEDs were not different between each AEDs, even though they possess different pharmacokinetic properties. Therefore, the CV of one AED can be used in determining the compliance of the epileptics who are taking multiple AEDs.

INTRODUCTION: Globally, cervical cancer is the fourth most common cancer in women, with about 85% occurring in low-middle income countries (LMIC) and an age-standardised incidence rate of more than 15 per 100,000. It is largely preventable through HPV vaccination and cervical cancer screening. In Singapore, 18% of the foreign domestic workforce hail from Indonesia, the Philippines, Myanmar, and India. However, there is no data on preinvasive cervical disease and cervical cancer in foreign domestic workers (FDWs) and the aim of this pilot programme is to determine the baseline screen positive rate of high-grade intraepithelial in this population. METHODS: A total of 322 FDWs were offered HPV screening through the Helping Our Helper (HOH) pilot programme. Data from this pilot programme were analysed and reported using simple descriptive statistics. RESULTS: Out of the 322 FDWs who registered for HPV screening, 68.6% participated. There was a 22.2% screen-positive rate; 10% of those who screened positive for high-risk HPV had histologically confirmed high-grade cervical intraepithelial neoplasia. This result is similar to other data on cervical cancer screening in Singaporeans. This pilot project screened less than 1% of the eligible FDWs in Singapore. DISCUSSION The findings of this pilot programme suggest that there is public health value in providing cervical cancer screening to FDWs. Improving cervical cancer screening by increasing awareness and including routine cervical cancer screening as part of the employment medical examination should be studied.

We investigated the role of the central MAPK pathways in extra-territorial (referred) pain resulting from inflammation of the temporomandibular joint (TMJ). Experiments were carried out on male Sprague-Dawley rats weighing 220-280 g. Under anesthesia, these animals were injected with 50 microL of complete Freund's adjuvant (CFA) into the TMJ using a Hamilton syringe. In the control group, saline was injected into the TMJ. To identify the extent of inflammation of the TMJ, Evans blue dye (0.1%, 5 mg/kg) was injected intravenously at 1, 3, 6, 9, 12 and 15 days after CFA injection. The concentration of Evans blue dye in the extracted TMJ tissue was found to be significantly higher in the CFA-treated animals than in the saline-treated group. Air-puff thresholds in the vibrissa pad area were evaluated 3 days before and at 3, 6, 9, 12, 15 and 18 days after CFA injection into the TMJ. Referred mechanical allodynia was established at 3 days, remained until 12 days, and recovered to preoperative levels at 18 days after CFA injection. This referred mechanical allodynia was observed in contralateral side area. To investigate the role of central MAPK pathways, MAPK inhibitors (10 microg) were administrated intracisternally 9 days after CFA injection. SB203580, a p38 MAPK inhibitor, significantly attenuated referred mechanical allodynia, as compared with the vehicle group. PD98059, a MEK inhibitor, also reduced CFA-induced referred mechanical allodynia. These results suggest that TMJ inflammation produces extra-territorial mechanical allodynia, and that this is mediated by central MAPK pathways.

INTRODUCTION: The impact of sex and diabetes mellitus (DM) on patients with heart failure with mildly reduced ejection fraction (HFmrEF) is not well elucidated. This study aims to evaluate sex differences in the clinical profile and outcomes in Asian HFmrEF patients with and without DM. METHODS: Patients admitted nationally for HFmrEF (ejection fraction 40-49%) between 2008 and 2014 were included and followed up until December 2016. The primary outcome was all-cause mortality. Secondary outcomes included cardiovascular (CV) death and/or heart failure (HF) rehospitalisations. RESULTS: A total of 2,272 HFmrEF patients (56% male) were included. More women had DM than men (60% versus 55%, P=0.013). Regardless of DM status, HFmrEF females were older, less likely to smoke, had less coronary artery disease, narrower QRS and lower haemoglobin compared to men. The odds of having DM decreases in smokers who are women as opposed to men (P_interaction =0.017). In multivariate analysis, DM reached statistical analysis for all-cause mortality and combined CV mortality or HF rehospitalisation in both men and women. However, the results suggest that there may be sex differences in terms of outcomes. DM (vs non-DM) was less strongly associated with increased all-cause mortality (adjusted hazards ratio [adj HR] 1.234 vs adj HR 1.290, P_interaction <0.001] but more strongly associated with the combined CV death/HF rehospitalisation (adj HR 1.429 vs adj HR 1.317, P_interaction =0.027) in women (vs men). CONCLUSION Asian women with HFmrEF had a higher prevalence of DM, with differences in clinical characteristics, compared to men. While diabetes conferred poor outcomes regardless of sex, there were distinct sex differences. These highlight the need for sex-specific management strategies.

INTRODUCTIONDeveloping effective exercise programmes for the paediatric population is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health and societal impact. In this study, the effects of a 12-week twice weekly additional exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises, in additional to typical physical education sessions, on aerobic fitness, body composition and serum C-reactive protein (CRP) and lipids were analysed in 13- to 14-year-old obese boys contrasted with a control group.

MATERIALS AND METHODSBoth the exercise group (EG, n = 12) and control group (CG, n = 12) participated in the typical 2 sessions of 40-minute physical education (PE) per week in schools, but only EG participated in additional 2 sessions per week of 45 to 60 minutes per session of exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises maintained at 65% to 85% maximum heart rate (HRmax = 220 - age). Body composition was measured using dual energy X-ray absorptiometry (DEXA). Fasting serum CRP and blood lipids were analysed pre- and postexercise programme. Aerobic fitness was measured by an objective laboratory submaximal exercise test, PWC170 (Predicted Work Capacity at HR 170 bpm).

RESULTSExercise training significantly improved lean muscle mass, body mass index, fitness, resting HR, systolic blood pressure and triglycerides in EG. Serum CRP concentrations were elevated at baseline in both groups, but training did not result in a change in CRP levels. In the CG, body weight increased significantly at the end of the 12-week period.

CONCLUSIONThis study supports the value of an additional exercise training programme, beyond the typical twice weekly physical education classes, to produce physiological benefits in the management of obesity in adolescents, including prevention of weight gain.
