Owen and Donna Williams, from Bridgend, were delighted when Mrs Williams gave birth to twins Grace and Logan after their third IVF attempt (newborns are pictured left, and with their parents, right). The pair had labelled several bottles of milk which Mrs Williams had expressed to be kept in a special fridge and given to the twins at feeding times. But last week, Mr Williams discovered a nurse had been feeding the twins from the wrong bottle, and believes the blunder occurred on at least three occasions. The pair now face an anxious three-month wait for test results in screening for infections such as HIV and hepatitis B. Abertawe Bro Morgannwg University Health Board confirmed the incident at the Princess of Wales Hospital in Bridgend took place and said the matter is under investigation. Mr Williams said: 'We are obviously completely distraught. Having waited eight years for our babies, they are incredibly precious to us and we placed all our trust in the care we were being given at the hospital.'

Abbie Kilbride, 18, from Renfrewshire, decided to celebrate having her braces removed by getting her teeth whitened. After being recommended someone who could do it, she went along hopeful for a gleaming smile. However, instead the teenager was left with a severely swollen lips and a series of painful blisters. She posted a warning on Facebook to others considering similar treatment.

AspireAssist is made up of a disk-shaped port valve that sits outside the body, connected to an internal tube to the stomach.Internally, surgeons connect a tube from the patient's stomach, attaching it to the port valve. After eating, the patient attaches an external connector and tube to the port valve. The valve is then opened and the stomach contents drained via the tube into the toilet. Once opened, the device takes five to 10 minutes to drain food from the patient.

Angelique 'Frenchy' Morgan asks Los Angeles-based surgeons Dr. Terry Dubrow and Dr. Paul Nassif to upgrade her implants on Tuesday night's episode of the E! reality series Botched. During her consultation (right), Frenchy insists that her breasts are too small and too far apart, however, the doctor's argue that her implants are perfect the way they are. And while she insists on getting 1,000cc implants, Dr. Dubrow tells her they can't be made that large.

The Government's guide to healthy eating could actually be causing obesity and type 2 diabetes, a nutritionist has claimed. The Eatwell Guide - created by Public Health England - is not based on evidence and was influenced by too many people with ties to the food industry, according to obesity researcher Dr Zoe Harcombe. The guide is a plate which visually represents the government's recommendations on food groups for a 'healthy, balanced diet' - and was first created in 1994. After the latest revision in March this year, it advised people to eat more fruit and vegetables, but almost half as many milk and dairy products like cheese and butter. It said 37 per cent of people's meals should be made up of bread, pasta, rice potatoes and other starchy carbohydrates - a 5 per cent rise on last year's plate. And some of the meal plans suggested containing as many as 2,250 calories a day - above the energy requirements for the average woman. Dr Harcombe is a clinical nutritionist based at the Institute of Clinical Exercise and Health Science, University of West of Scotland. She said the advice to base meals on carbohydrates and reduce fat is not based on evidence and has not been tested.

Sam Tai's memory completely wiped itself every 24 hours, like Drew Barrymore's character in the film 50 First Dates (top right). As a result of brain damage during a rugby match earlier this year, the 17-year-old from York had to relearn his entire life - including who his parents are - only to forget them again the next morning. He would work out what type of music he liked by searching his YouTube history, and could not remember doing his GCSEs. Now, the teenager has beaten his amnesia and incredibly, he has regained every single memory.

A 20-week scan revealed Isabella Grote, from North Dakota, had the rare birth defect encephalocele. The condition occurs when the neural tube, that forms the brain and spinal cord, does not close completely during early stages of pregnancy. It caused part of her brain to grow through an opening at the back of her skull (left). She was given a slim chance of survival when she was delivered by Caesarean section. At just three days old, she needed lifesaving surgery to have the sac removed and the small part of her brain placed back in her skull. There was a high chance she would have severe disabilities but she has continued to astonish doctors with her progress. Now four (right), Isabella is thriving and hitting all of her milestones. Mother Sharlotte said: 'We feel truly blessed to have our beautiful little girl with us today. She has been through more than most people have to go through in a lifetime.'

Melissa Mead, 29 (left), from Cornwall, lost her son William, one (right), after medics failed to diagnose the deadly condition. He began suffering a chesty cough, but medics failed to diagnose the deadly condition. An inquiry after his death revealed that there had been a staggering 15 failures in his care. Since, she has become an expert on the subject, campaigning to raise awareness and ensure others don't die needlessly. But only months ago, she learned that she herself had almost died from the condition. Following surgery in 2011, she became critically ill with an infection and her medical notes reveal it was sepsis. The revelation that the infection was sepsis came during a session with the psychiatrist who has treated her for depression and post-traumatic shock since William died. Now five months pregnant with her second child, she is beset by guilt that she is alive while William died. 'I'd have given my last breath so my child could live,' she said.

Jasmine Moxom, 3, (left in both photos) was born with spastic diplegia, a form of cerebral palsy, which affects her lower limbs and means she struggles to walk (right). She had scans and X-rays before being referred to Bristol Hospital to prepare for surgery. But hopes of running around with twin Summer (right) are in doubt now the NHS said it could not fund it. Her parents Sally Morton and Ricky Moxom are furious after being told they will have to raise the £30,000 themselves. Ms Morton said: 'The NHS need to realise they can't go promising children one thing and then take it away without a care, it's disgusting.'

Malin Stenberg was only 15 when she was told she had been born without a womb and so would never carry a child of her own. But now she has spoken of the magic of motherhood after becoming the world's first woman to have a baby with a womb transplant. Miss Stenberg, 38, said she wanted to tell her story to give hope to others in the same situation. 'If you wish for a family and you are unable to have one naturally, for whatever reason, it is so sad,' she said. She is pictured with her son Vincent and his father Claes Nilsson (inset).

A New York woman aiming to strengthen her pelvic muscles got off to a rough start when the kegel-enhancing eggs she used burned the inside of her vagina. Rebecca Jane Stokes, 32, bought stone marble eggs from Etsy to help her enhance her Kegel exercises. She followed the instructions to boil them first, ensuring they'd be clean. Once they no longer felt hot, she inserted one inside of her - though when it was in, it was much hotter than she'd imagined.

Beverley Davies, from Rotherham, South Yorkshire, shed two stone - going from 12st 6lbs to 10st 7lbs (left before and right after) - in just three months when she began the process, and now claims she can keep the weight off without dieting. The 49-year-old tried fad diets when she was younger but said they never worked for her - unlike her self-hypnosis, which means she feels full after just a few bites of her meal. The mother's daily hypnosis sessions usually last about 10 minutes and are carried out first thing in the morning before being followed by 20 minutes of yoga.

Calorie Brands has re-imagined famous food brands with the calorie content replacing the logo.

Doctors want me to bring my eldest daughter, who is just 11, in for a scan. To find out whether she has a womb. And honestly, I am not sure I want to know, writes KATIE HOPKINS (pictured right, and left with her family). My perfect-looking daughter was born with all the things you pray for: ten fingers, ten toes, hands that curl around a finger and legs tucked up tight under her chin. She was also born with a genetic abnormality, the 'HNF1B gene deletion', which affects kidneys, pancreas, liver and the reproductive system.

Health experts have today warned teenagers of the dangers of drinking a cocktail of racing fuel and Mountain Dew, known as 'DewShine'. It comes six months after two teen boys died in rural Tennessee, having drunk the concoction - which includes methanol. Logan Stephenson, a 16-year-old student at Greenbriar High School, was found dead in his bed the morning of January 21. Just minutes later, paramedics were called to Stephenson's best friend J.D. Byram's house, when the boy started having seizures. Five days later, J.D died in hospital from the effects of the drink. In a report released today, the Centers for Disease Control and Prevention documents investigations into the two deaths. Experts urge parents, teachers, community leaders and healthcare professionals do warn young people of the dangers of drinking 'DewShine'.

Sophie Trew, 25, had been to Colombia to film a documentary (left) after graduating from the University of Sheffield. When she returned, she felt tired and lethargic but thought she was simply recovering from her trip. It was only when she developed a lump on her neck she sought medical advice and was diagnosed with Hodgkin lymphoma. She started six months of chemotherapy (right) and also embarked on living a healthier lifestyle, cutting out a lot of sugar, dairy and gluten. Now she has been given the all clear (inset) and believes this has contributed to her recovery. She said: 'It's woken me up. I have more energy now than I did before I was ill, and I know it's all down to lifestyle changes.'

Helen Stephens, 53, of Wednesbury, in the Black Country, has been left crippled by Stiff Person Syndrome (SPS) - a rare neurological disorder affecting one person in every million. She regularly suffers attacks which means her muscles tear and expand, making her swell by four inches - which she says feels like she has 'red hot pokers' under her skin (left and right during an attack). She has been stuck in her lounge since 2011 (pictured left) when a specially adapted back bedroom was flooded - and claims her local council are about to cut her funding even further. She said: 'I think the help out there for vulnerable adults in their 50s is horrendous. I know of others struggling too and we are not treated right.'
