OBJECTIVES: Transcranial sonography of the substantia nigra for diagnosing premotor stages of Parkinson disease has been attracting increasing interest. Standard reference values defining an abnormal increased echogenic size (hyperechogenicity) of the substantia nigra have been established in several populations using high-end stationary ultrasound systems. It is unknown whether a portable ultrasound system can be appropriately used and how the Filipino population would compare with the well-studied white population.
METHODS: We prospectively studied substantia nigra echogenic sizes and third ventricle widths in 71 healthy adult German participants and 30 age- and sex-matched Filipino participants using both a well-established stationary ultrasound system (in the German cohort) and a recently distributed portable ultrasound system (in both ethnic cohorts).
RESULTS: Mean substantia nigra echogenic sizes, cutoff values defining abnormal hyperechogenicity, and intra-rater reliability were similar with both systems and in both ethnic cohorts studied. The Filipino and German participants did not differ with respect to the frequency of insufficient insonation conditions (each 3%) and substantia nigra hyperechogenicity (10% versus 9%; P = .80). However, third ventricle widths were smaller in the Filipino than the German participants (mean ± SD, 1.6 ± 1.1 versus 2.4 ± 1.0 mm; P = .004).
CONCLUSIONS: The frequency of substantia nigra hyperechogenicity appears to be homogeneous in white and Asian populations. Screening for this feature may well be performed with a present-day portable ultrasound system.

Lichen planus (LP) is a chronic mucocutaneous inflammatory condition that typically affects middle-aged adults. Esophageal involvement in LP is rare and underrecognized, often leading to delayed diagnosis and treatment of LP. Herein, we describe three cases of esophageal LP (ELP) in clinically symptomatic patients with endoscopic lesions in the upper to mid-esophagus. This case series suggests that ELP is be more common than was previously thought and emphasizes that clinicians should have a high index of suspicion for this diagnosis, particularly when evaluating proximal esophageal lesions in patients presenting with dysphagia. The series also highlights the successful treatment of our patients with budesonide-honey slurry.

X-linked dystonia parkinsonism (XDP) is a rapidly progressive and disabling neurodegenerative disease affecting mainly male Filiponos with origins from Panay Island. We reviewed all the past neurosurgical ablative procedures done for XDP patients listed in the Philippine XDP registry. From 1960 to 1982, six patients had undergone bilateral chemopallidotomies or bilateral thalomotomies stage over time. Half of these patients had significant improvement in their symptoms but five of the six patients (83%) developed postoperative morbidities, mainly speech impairment or hemiparesis, All the five reported GPi deep brain stimulation (DBS) cases for XDP were also reviewed, showing consistently immediate improvement of symptoms (61.5%-88.3% decrease in the Burke-Marsden Dystonia Rating Scale) lasting up to a year with effects noted. We also present the first Philippine case of GPi DBS done in the youngest XDP patients to date. This present case showed dramatic improvement(83.3% desrease of the Burke-Marsden_Fahn Dystonia Rating Scale) of his dystonic symptoms, without incurring any persistent adverse effects. The results of these early cases of pallidal DBS for XDP show that DBS is generally a safe and effective procedure for alleviating the disabling symptoms of XDP in contrast to previous ablative surgeries on these patient

PURPOSE: We report our experience to date with 171 patients who underwent laparoendoscopic single-site surgery for diverse urologic diseases in a single institution. MATERIALS AND METHODS: Between December 2008 and August 2010, we performed 171 consecutive laparoendoscopic single-site surgeries. These included simple nephrectomy (n=18; robotic surgeries, n=1), radical nephrectomy (n=26; robotic surgeries, n=2), partial nephrectomy (n=59; robotic surgeries, n=56), nephroureterectomy (n=20; robotic surgeries, n=12), pyeloplasty (n=4), renal cyst decortications (n=22), adrenalectomy (n=4; robotic surgeries, n=2), ureterolithotomy (n=10), partial cystectomy (n=3), ureterectomy (n=1), urachal mass excision (n=1), orchiectomy (n=1), seminal vesiculectomy (n=1), and retroperitoneal mass excision (n=1). All procedures were performed by use of a homemade single-port device with a wound retractor and surgical gloves. A prospective study was performed to evaluate outcomes in 171 cases. RESULTS: Of the 171 patients, 98 underwent conventional laparoendoscopic single-site surgery and 73 underwent robotic laparoendoscopic single-site surgery. Mean patient age was 53 years, mean operative time was 190.8 minutes, and mean estimated blood loss was 204 ml. Intraoperative complications occurred in seven cases (4.1%), and postoperative complications in nine cases (5.3%). There were no complications classified as Grade IIIb or higher (Clavien-Dindo classification for surgical complications). Conversion to mini-incision open surgery occurred in seven (4.1%) cases. Regarding oncologic outcomes, no cancer-related events occurred during follow-up other than one aggressive progression of Ewing sarcoma. CONCLUSIONS: Laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases; however, surgical experience and long-term follow-up are needed to test the superiority of laparoendoscopic single-site surgery.

BACKGROUND: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. METHODS: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. RESULTS: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderateintensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisuretime physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. CONCLUSION: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

INTRODUCTIONIn Singapore, the age-standardised event rates of myocardial infarction (MI) are 2- and 3-fold higher for Malays and Indians respectively compared to the Chinese. The objectives of this study were to determine the prevalence and quantity of coronary artery calcification (CAC) and non-calcified plaques across these 3 ethnic groups.
MATERIALS AND METHODSThis was a retrospective descriptive study. We identified 1041 patients (810 Chinese, 139 Malays, 92 Indians) without previous history of cardiovascular disease who underwent cardiac computed tomography for atypical chest pain evaluation. A cardiologist, who was blinded to the patients' clinical demographics, reviewed all scans. We retrospectively analysed all their case records.
RESULTSOverall, Malays were most likely to be active smokers (P = 0.02), Indians had the highest prevalence of diabetes mellitus (P = 0.01) and Chinese had the highest mean age (P <0.0001). The overall prevalence of patients with non-calcified plaques as the only manifestation of sub-clinical coronary artery disease was 2.1%. There was no significant difference in the prevalence of CAC, mean CAC score or prevalence of non-calcified plaques among the 3 ethnic groups. Active smoking, age and hypertension were independent predictors of CAC. Non-calcified plaques were positively associated with male gender, age, dyslipidaemia and diabetes mellitus.
CONCLUSIONThe higher MI rates in Malays and Indians in Singapore cannot be explained by any difference in CAC or non-calcified plaque. More research with prospective follow-up of larger patient populations is necessary to establish if ethnic-specific calibration of CAC measures is needed to adjust for differences among ethnic groups.
