3 gastroenteritis cases at Hong Kong hospital unrelated, investigation finds
The Centre for Health Protection also said in revealing the outcome of its investigation on Friday that the young oncologist who died had traces of a certain kind of rotavirus, rather than the previously thought Shiga toxin-producing E coli (STEC), but that his cause of death was 'uncertain'.
An expert from the investigating team suggested it was the first time that a particular strain of the rotavirus had been detected in Hong Kong, but there was no evidence of a community outbreak.
The death of the young doctor at Princess Margaret Hospital in February prompted concerns that an outbreak of the toxic strain had emerged after it was found in the stool sample of one of the doctors who suffered milder symptoms.
'Based on the available information, the [centre] confirmed that there was no STEC outbreak in the oncology department of [the hospital] and that there was no linkage between the illnesses of the three doctors,' it said.
The investigation, which included an expert team from the department of microbiology at the University of Hong Kong (HKU), found that a stool sample of the doctor who was suspected of having a STEC infection did not grow 'viable' bacteria of the infectious strain.

University of Hong Kong scientists explore growing organs with 3D printing tech
Scientists from the University of Hong Kong (HKU) are attempting to integrate 3D-printed respiratory tissue with lab-grown 'mini-organs' to help patients in need of transplants in the future. Professor Michael Chan Chi-wai from HKU's Centre for Immunology and Infection said his team was looking to produce personalised 3D-printed airways for burn victims using organoids or 'mini-organs' grown from patients' own cells collected through a single oral swab. 'Airways are one of our strengths and an area we have dedicated significant time to. When people suffer from burn injuries, they may need to reconstruct their airway,' said Chan, who also belongs to the division of public health laboratory sciences at HKU's medical faculty. 'Existing technologies allow the 3D printing of an airway using biomaterials. But without the cells, it cannot perform the functions of an airway.' Organoids are developed using a person's stem cells and can mimic the function and structure of the actual organs of a specific patient. They can be used to test a certain person's reaction to medicine, vaccines or diseases. According to Chan, HKU is one of the world's leading institutions in the research and development of respiratory organoids. The university has set up a spin-off company called C2iTech, specialising in personalised organoid cultivation.

Are you developing Parkinson's disease? Earwax may show if you are at risk, study says
Chinese researchers investigating Parkinson's disease have made a curious discovery related to earwax that could improve the prospects of prevention and diagnosis. A team based at Zhejiang University in Guangzhou has found that earwax tests could help with the early detection of the debilitating disease, which is difficult to treat and has no cure. Earwax from people with Parkinson's disease were significantly different than the earwax from people without the disease,' according to the American Chemical Society, which published the team's findings. The researchers were following up on previous work showing that Parkinson's sufferers' sebum – an oily substance secreted through the skin – has a different odour than that of people without the disease. Since earwax is largely made up of sebum, the team realised it would make for a potentially telling research target. Earwax is a naturally occurring substance produced in the ear canal to protect and clean the ear. Photo: dpa After screening samples taken from more than 200 people, the team found alterations in four volatile organic compounds – organic chemicals that easily evaporate into the air – in Parkinson's patients' earwax. These changes do not appear in the compounds in the sebum of those who do not have Parkinson's.

Thailand's doctors have to show cannabis use for medical reasons in new form
Thailand has introduced a new prescription form as part of its measures to restrict cannabis usage for medical purposes, just three years after it became the first country in Asia to decriminalise the drug. Advertisement Issued on Monday, the 'P.T.33' form will allow practitioners from seven professions — including doctors, dentists, pharmacists and traditional healers — to prescribe cannabis to patients suffering from 15 health conditions, according to a report from the Thaiger news website. Doctors will be required to record in each prescription form patient details, including name, age, nationality, identification number, diagnosed symptoms, daily cannabis dosage, duration of use and total quantity to be dispensed. The amount sold will be limited to 30 days' supply for each prescription, and dispensers are required to keep such records for one year for government inspections. The prescription form, which will apply to both locals and foreigners, will take effect soon. A cannabis farm in Kanchanaburi province, Thailand.
