In selected patients with aggressive orofacial cancer, the submental flap is an expedient alternative to free tissue transfer for reconstruction. Nonetheless, indiscriminate use might compromise the oncological outcome, so it cannot be regarded as a standard method of treatment.

Background: The Hong Kong Poison Information Centre (HKPIC) provides consultation service to health care professionals and collect epidemiological data on poisoning in Hong Kong since 2005. Objective: To report and analyse the data of Hong Kong Poison Information Centre on poisoning in 2019. Methods: This was a retrospective review of all poisoning cases recorded in the Poison Information and Clinical Management System of Hong Kong Poison Information Centre in 2019. Results: A total of 4016 poisoned cases were analysed, which involved 1698 men (42.3%), 2312 women (57.6%) and 6 sex-unspecified patients (0.1%). Majority of cases (77.3%) were between 13 and 69 years of age, and 10.5% were teenagers 13–19 years of age. Self-harm/suicidal attempt (42.1%), unintentional exposure (18.1%) and abusive substance use (11.1%) were common reasons of poisoning. Excluding ethanol, which was the common co-ingestant, the five most common types of poison were benzodiazepines, paracetamol, household products, zopiclone and Chinese herbal medicine. While most patients were managed with supportive treatment, 16.5% and 16.8% of the consultation cases were treated with decontamination and antidotes, respectively. Majority of cases recovered uneventfully, but 1.0% died and 4.7% had a major outcome. A total of six interesting cases and two outbreaks were discussed in this report. Conclusion: This 14th annual report provided updated epidemiological information on the pattern of poisoning in Hong Kong and highlighted a number of important changes compared with our previous reports.

The tradition of Chinese Medicine (TCM) has been in use and development for thousands of years, where it has been applied in some form for the treatment of nearly every common illness. TCM is currently undergoing a resurgence in interest and in providing an adjunct to allopathic medical care virtually worldwide. TCM therapeutics may be administered in many forms from capsules, to powders, homogenates, tinctures and decoctions. Si Wu Tang, a derivative of the traditional Chinese including Formulas, is a combination of substances that may function in a synergistic manner to promote a calming effect and an amelioration of symptoms of hypertension. Such formulas are often used in TCM to treat or alleviate a wide range of the common illness and disorders of both Eastern and Western society. Reported beneficial effects include improvements in circulatory, cardiovascular, mood, endocrine metabolic and reproductive disorders. One such TCM formula commonly recommended is the Wu Cao Si Wu Tang [SWT]formula, used to treat the hypertension of obesity and a variety of other disorders. Hypertension is a key risk factor for cardiovascular morbidity and mortality and is a leading cause of end-stage renal disease; over 7 million US deaths per year may be directly attributed to pathophysiologic complications resulting from poor control of blood pressure. While numerous advances in the diagnosis and treatment of hypertension have had a major impact on decreasing the overall risks and an improved management of this chronic disease, a definitive cure for all causes of hypertension has remained elusive to date. To determine the comparative effectiveness of conventional Western treatment vs. drug free Traditional Oriental Therapy for hypertension, we reviewed the data from independent studies. Wu Cao Si Wu Tang was found to be as effective as allopathic medications in controlling blood pressure in a group of moderately hypertensive patients

Objectives: To report and analyse the poisoning data of Hong Kong Poison Information Centre in 2017. Methods: In 2017, all poisoning cases received by Hong Kong Poison Information Centre were retrieved from its database (Poison Information and Clinical Management System) for analysis. Results: A total of 3956 poisoned cases were analysed. There were 1789 male patients (45.2%), 2159 female patients (54.6%) and 8 sex-unspecified patients (0.2%). The majority of cases (59.9%) were between 20 and 59 years old. The common causes of poisoning were suspected self-harm/suicidal attempt (36.2%), unintentional exposure (18.6%) and abusive substance use (13.7%). Excluding the common co-ingestant ethanol, the five commonest types of poison were benzodiazepines, paracetamol, zopiclone, Chinese herbal medicine and household products. Most patients were managed with supportive measures, while 17.4% and 13.2% of consultation cases were treated by decontamination and antidotes, respectively. The majority of the cases had uneventful recovery; 1.1% resulted in death and 4.3% had major outcomes. A total of 13 interesting cases and 1 poisoning outbreak were discussed. Conclusion: This 12th annual report provided the updated epidemiological information on poisoning pattern in Hong Kong and highlighted important changes in comparison with our previous reports.

Objective: The aim of this study was to report and analyse the poisoning data of Hong Kong Poison Information Centre in 2018. Methods: In 2018, all poisoning cases received by Hong Kong Poison Information Centre were retrieved from its database, Poison Information and Clinical Management System, for analysis. Results: A total of 3960 poisoned cases were analysed. There were 1770 male patients (44.7%), 2188 female patients (55.3%) and 2 sex-unspecified patients (<0.1%). The majority of cases (68.3%) were between 20 and 69 years old, and 9.9% involved children of 0–5 years old. The common causes of poisoning were suspected self-harm/suicidal attempt (36.6%), unintentional exposure (18.4%) and abusive substance use (11.1%). Excluding the common co-ingestant ethanol, the five commonest types of poison were benzodiazepines, paracetamol, Chinese herbal medicine, household products and zopiclone. Most patients were managed with supportive measures, while 13.5% and 13.7% of consultation cases were treated by decontamination and antidotes, respectively. The majority of cases had uneventful recovery; 0.8% resulted in death and 4.9% had major outcomes. A total of eight interesting cases were discussed. Conclusion: This 13th annual report provided the updated epidemiological information on poisoning pattern in Hong Kong and highlighted important changes in comparison with our previous reports.

A case of bilateral temporomandibular joint (TMJ) ankylosis in a Chinese male patient with ankylosing spondylitis is presented. A review of the literature emphasizes the rarity of this arthro-pathology in ankylosing spondylitis. The importance in the recognition of this complication by clinical examination supplemented by computed tomography is stressed.

Three hundred Chinese patients with cleft lip and/or palate were reviewed in the Dentofacial Deformities Clinic of the Department of Dentistry at the United Christian Hospital between January 1990 and January 1992. A survey was taken of patients' age, sex, type of cleft, and cleft location. The findings from this survey are compared to an original sample of 2800 cleft patients surveyed earlier.
