<b>OBJECTIVEb>Epidemiologic studies in Caucasian populations suggested that symptomatic obstructive sleep apnea (OSA) occurred at a prevalence of 1-10%. The condition has been increasingly recognised among the Chinese in Hong Kong. We therefore, summarize our experience with OSA at the Department of Medicine, The University of Hong Kong at Queen Mary Hospital from 1985-1996.

<b>METHODSb>All clinic records concerning demographic data, anthropometric data, clinical features, polysomnographic findings and treatment were reviewed.

<b>RESULTSb>One hundred and twenty-two patients were diagnosed to have OSA. Demographic and clinical features were similar to Caucasian data with a male predominance of 84%, a mean age of about 50 years, and obesity as a risk factor at a mean body mass index of 30.4, which was higher than that of the average local population, although lower than that of OSA patients in Caucasian series. About 27% of the patients have a body mass index (BMI) similar to or below the population average. Nearly all were habitual snorers, and the majority had excessive daytime sleepiness. On polysomnography, the mean apnea-hypopnea index was 38. Common associated medical conditions were hypertension (34%), diabetes mellitus (10%), ischemic heart disease (9%), hyperlipidemia (6%). Most patients were managed successfully with nasal continuous positive airway pressure. Treatment with oral appliances for milder cases is being explored.

<b>CONCLUSIONSb>OSA has been increasingly recognised among Chinese adults in Hong Kong in the past decade. Demographic features were similar to Caucasian data. The majority of patients were overweight, although 27% were not, and further investigation on the contribution of faciomaxillary morphology to OSA in this group is warranted.

Metastatic mature teratoma is a common radiologic and histopathologic finding after chemotherapy for metastatic nonseminomatous germ cell tumors. The leading theory for these residual tumors is the selective chemotherapy resistance of teratomas versus the high chemotherapy sensitivity of the embryonal components. Growing teratoma syndrome is a relatively rare phenomenon defined as an enlarging residual mass histologically proven to be a mature teratoma in the setting of normal serum tumor markers. Metastatic mature teratomas should be resected because of their malignant potential and occasional progression to growing teratoma syndrome with the invasion of the surrounding structures. CT is the preferred imaging modality for post-chemotherapy surveillance and should cover all sites of potential metastatic disease. This article reviews the clinical, pathologic, and multimodality imaging features of metastatic mature teratomas in patients with primary testicular non-seminomatous germ cell tumors.

With the advent of modern surgical techniques, paediatric cataract has become much more manageable. Intraocular lens (IOL) implantation is the standard of care for patients over the age of 2 years. The use of IOL in young infants is still controversial. In addition, there are still unresolved issues, such as the minimum age at which IOL can be safely implanted, IOL power selection and IOL power calculation. The current trends in the management of the above challenges are discussed. Although numerous reports on the prevention and management of posterior capsule opacification have been published, there are ongoing intensive debates and research. Long-term postoperative complications like glaucoma and rhegmatogenous retinal detachment are problems that cannot be overemphasised and these issues are also reviewed.

Osteonecrosis of the femoral head (ONFH) is a devastating disease frequently leading to femoral head collapse and hip arthritis. Specifically, non-traumatic ONFH primarily affects young and middle-aged adults. Although compromised local circulation of the femoral head seems to be pathognomonic for the disease, the pathogenesis is perplexing and continues to be an area of scrutiny and research. Comprehension of the pathogenesis is of crucial importance for developing and guiding treatments for the disease. Therefore, we provide an up-to-date consensus on the pathogenesis of non-traumatic ONFH.

INTRODUCTION: 68Ga-PSMA PET is an effective imaging modality in the evaluation of prostate cancer. However, there is limited data on its use in the evaluation of therapeutic response, particularly in radioligand therapy. OBJECTIVE: Our aim is to investigate the diagnostic accuracy of 68Ga-PSMA PET hybrid imaging in evaluating response to 177Lu-PSMA therapy in patients with mCRPC compared with the standard use of serum PSA. METHODOLOGY: A systematic review was done according to the Cochrane diagnostic accuracy reviews guidelines and the PRISMA checklist of literature from January 2015 to August 2020. Literature search, study selection, and data extraction were conducted by 2 reviewers. Statistical analysis of data was done using Meta-DiSc v1.4 RESULTS: A total of 5 studies were included following screening. A total of 128 patients were included in the review. Using PSA response as the reference standard, the pooled sensitivity and specificity of 68Ga-PSMA PET hybrid imaging to evaluate treatment response to 177Lu-PSMA therapy was 85% (Cl: 74 to 92%) and 74% (Cl: 62 to 84%), respectively. The computed diagnostic accuracy was 79.7%. CONCLUSION 68Ga-PSMA PET hybrid imaging is an effective diagnostic procedure in evaluating treatment response to 177Lu-PSMA therapy ligand therapy with good sensitivity, specificity, and diagnostic accuracy.

The Philippines, with a maximum personal income tax rate at 32%1 and a corporate income tax of 35%,1 has one of the highest income tax rates among the Association of South East Asian(ASEAN) member states.2 The new administration is now campaigning to lower the ceilings on capital and personal income tax, through a proposal originally passed in September 2016, and amended in January 2017, following public and private sector opposition for its immediate imposition.3 In its Explanatory Note, House Bill No. 292, "An Act Imposing Excise Tax on Sugar-Sweetened Beverages by Inserting a New Section 150-A in the National Internal Revenue Code of 1997, as Amended," cites this as the reason for imposing an, "excise tax of ten pesos (Php 10.00) on sugar-sweetened beverages, the rate of which shall be increased by four percent (4%) every year thereafter effective on January 1, 2017."4 According to the proposed bill, "this measure is proposed to provide additional revenue collections for our country," further claiming that, "this house bill is timely in its submission as one of the new administration's policies to pursue reforms in income tax rates.

Non-traumatic osteonecrosis of the femoral head (ONFH) usually affects adults younger than 50 years and frequently leads to femoral head collapse and subsequent arthritis of the hip.It is becoming more prevalent along with increasing use of corticosteroids for the adjuvant therapy of leukemia and other myelogenous diseases as well as management of organ transplantation. This review updated knowledge on the pathogenesis, classification criteria, staging system, and treatment of ONFH.
