The arrival of the New Year traditionally brings along a list of New Year’s resolutions and new goals to be achieved, and usually on the top of the list for many there is a resolution to stop smoking. The advantages of doing so are many, the first being prevention of lung cancer, given that 90% of cases diagnosed are due to smoking.

Last year 28,645 new cases of lung cancer were diagnosed in Spain. This type of cancer has become the third most frequent in Spain and for that reason, Vithas Xanit International Hospital, part of the Vithas health group, insist on the importance of early detection of this disease, as well as raising awareness among the population about the dangers of smoking.

Today we want to help all of you who have set as a challenge for 2019 to quit smoking by offering you these simple tips to make your decision much more manageable.

  1. Before you lit a cigarette, ask yourself, “Why do I smoke?”If you pause to think about it, you will discover that smoking is not about the actual physical necessity, but because of the habit acquired.
  2. List the reasons why you continue to smoke, and why you should quit, you will be surprised by the difference in pros and cons. This list can also help you in moments of weakness when you want to smoke a cigarette again. You can go back to your list and remember the reasons why you are quitting this deadly habit.
  3. Set short-term goals and replace smoking with healthier habits that you should gradually include in your life. Starting exercise (better if in a group), drinking plenty of fluids, and a diet rich in fruit and vegetables can help quit smoking.
  4. Seeking help is also necessary, and we are not just talking about professional advice, but about support from the people around you, your friends, colleagues and family members. It is crucial that family and friends know about your decision to quit smoking so that they can be part of your goal, for this will encourage you not to lit a cigarette in front of them.
  5. If you smoke more than 10 cigarettes a day, it is also recommended to seek help from a specialist who will provide you with adequate medical treatment, since 70% of smokers in the hands of specialists manage to quit smoking, limiting the percentage to only 5% of those who decide to stop smoking without help.

 

At Vithas Xanit, we have a team of pulmonologists who provide patients with personalised care to stop smoking, with specially designed sessions where we offer customised treatments adapted to the characteristics and needs of the patient.

On Friday, the 4th of January, Vithas Xanit International Hospital had a visit from the Three Wise Men, much to children amusement, both those who were hospitalised and those who at the time were found in the Paediatric Emergency Room and the Paediatric Outpatient Clinics.

The Three Kings or the Three Wise Men, further to visiting the hospitalised children, marked the Vithas Family Day along with the children of the hospital’s staff, with a guided tour of the hospital that ended in the Congress Hall where all the children present received a gift.

Here are a few photos from the visit.

Hair transplant in Spain

Posted by Xanit Internacional Xanit Internacional | Posted in Xanit salud | Posted on20-06-2019

Hair transplant is the technique that consists in extracting hair, follicle by follicle, from an area of the head (which is the donor zone and is usually the back of the head) to be subsequently implanted in the area affected with alopecia (i.e. the receiving area that we want to repopulate). The most common cause of hair loss is androgenetic alopecia, that is, hair loss due to genetic causes (heredity) and as a consequence of the action of testosterone (which is the male hormone).

Today we delve into this technique with Dr Miguel Valenzuela, the latest addition to the Herrera Clinic for this type of interventions, serving patients throughout Vithas Costa del Sol hospitals, all equipped with the state-of-the-art technology, professional staff and means necessary to ensure patients’ satisfaction with the best aesthetic results.

Techniques

There are two techniques for capillary graft: FUE (“Follicular Unit Extraction”, e.g. removal of follicles one by one) and FUSS (also called “Strip”, where a piece of skin is removed from the scalp, then the follicles are sectioned and extracted).

The FUSS technique leaves a scar that occupies the entire back of the head (ear to ear), due to which this technique is less performed.

The results of both techniques are similar, however, most patients decide on the FUE since there is no scar left. Furthermore, these techniques do not require general anaesthesia, the capillary micrograft is performed under local anaesthesia and is done on an outpatient basis. There is no need for the patient’s hospitalisation either.

Dr Miguel Valenzuela explains how the use of this technique (FUE) allows us to obtain more natural results and avoids the scarring that was previously left on the back of the head. After the transplant, there are only a few small crusts left, from the extraction of the hair, which fall off within 15 days. Once the procedure is performed, the patient only has to wait four days to wash the transplanted hair, and then use a mild neutral shampoo, and avoid rubbing the hair for a couple of weeks. For the FUE technique, the follicles are removed from the neck and then transplanted, hair by hair, to the front of the head or where the bald patches are. This intervention is performed in the operating theatre and, depending on the follicles to be removed, and the hair to be transplanted, lasts between 5 and 8 hours.

This type of hair transplant has shown high success rates, without graft rejection since the hairs transplanted are from the same patient.

The good transplantation results are not immediately perceived, however, are guaranteed. Transplanted hair falls out during the first weeks after surgery, but the root and the cells in the follicle begin to grow from the 3rd month and in less than a year hair growth is definitive. The hair obtained with this technique is permanent although, of course, the hair ages at the same rate as the rest of our body.

Treatment

The surgery lasts approximately 5 to 8 hours, depending on the number of units to be implanted. Usually, the patient spends the first part of the surgery sleeping (the extraction phase), and then during implantation may be watching movies or listening to music, as he is conscious at all times. Usually, one capillary graft session is sufficient, however, if the alopecia zone is big, and the donor zone is reduced, it is necessary to perform two surgeries 3 to 6 months apart, to distribute the extraction between the two surgeries and not damage the donor area.

After transplantation there is no chance of losing hair again, transplanted hair does not fall out any more. It is important to start taking finasteride and use minoxidil after transplantation to prevent the patient’s own, non-transplanted hair from falling out.

Hair transplant abroad

The main reason why people decide to undergo such an intervention outside Spain is money. There are countries where the government subsidises part of the surgery cost to attract patients.

However, there are many risks involved, such as the lack of sanitary controls in the clinics, the transplant not being done by a doctor but a member of staff who sometimes is not even sanitary, the possibility of infection or the lack of follow-up after transplantation.

Another common problem in these countries is that in order to implant the number of follicular units they advertise, they often cut off the follicular units, with the great risk of damaging them.

In Spain, there are excellent healthcare professionals and the price of transplantation is very reasonable, besides having the quality guarantees of the Spanish Health System, which is undoubtedly one of the best in the world.

Hip prosthesis in elderly patients

A hip prosthesis is an implant that replaces a malfunctioning hip joint, with traumatic or degenerative pathology.

In both cases, patients undergoing hip prosthesis are mainly over the age of 60. After implantation of a hip prosthesis, the pain is alleviated, thus improving the quality of patient’s life. It also increases the patient’s autonomy. The patient can practically have a normal life, including doing sports activities.

 

Causes

Arthrosis is one of the causes of dysfunctional loss for which the placement of a prosthesis is indicated. Also in cases of fractures of the femur neck. On the other hand, there are situations in younger people where there is insufficient blood supply and hip necrosis occurs, where the placement of a prosthesis may be indicated. If the patient decides to undergo surgery, the process consists of a very common and systematised surgical procedure, so the possible complications are very low.

The rate of infection and thromboembolism are less than 0.5%. The probability of dislocation is also very low.

 

Recovery

After implantation of the prosthesis, the patient starts with physiotherapy, and on the second postoperative day, can sit down in a chair and start walking with crutches. The patient is discharged on the 5th post-op day with the autonomy to walk with crutches or walker.

Stitches are removed two weeks after the surgery, and a month later, the patient can have a practically normal life. The need for support will depend on the degree of autonomy that the patient had before the placement of the prosthesis. If the patient is autonomous, he will not need special help.

When indicated, a hip prosthesis is a magnificent solution to improve the quality of life of the patient at low risk. We highly recommend it if the patient fits the clinical criteria required.

Use of X-rays in patients, is it safe?

Many of us would like to know what happens when we undergo a diagnostic test, particularly tests with equipment emitting X-rays or radioactive isotopes in nuclear medicine. In these cases, the question arises whether they pose a risk to our health and whether they are indispensable.

Today, Dr Manzano, Head of the Medical Physics and Radiological Protection Department at Vithas Xanit International Hospital, tells us how safe is the use of X-rays and isotopes in Nuclear Medicine and what progress we are making regarding the information available to the patient.

How safe are X-rays?

Almost everything we do in our day to day life carries some degree of probability of complication, contemplated as risks of the kind, one in a thousand or one in a million.

An activity should be considered safe when the risk of an adverse effect occurring is less than one for every million times repeated: that is, what probability would it be if we repeated the same activity thousands or millions of times.

We are all fully aware of the fact that since its discovery, X-rays were one of the most significant advances of humanity, and they have allowed the medicine to understand how diseases occur within the human body without having to cut it open, saving the lives of millions of people. The X-ray machine was chosen as the most important scientific invention in the world, surpassing even penicillin (London Science Museum Survey).

For most studies, the dose received may be the same as that received by any person NOT subjected to an X-ray test in a year. The more complex and time-consuming studies can be equivalent to several years of natural radiation, still being at low risk, between one in hundred thousand and one in ten thousand.

As for the risk of developing some malignant disease, we need to know that the risk in chest or limb studies is considered minimal, less than one in a million. We can also make a comparison by saying that a test of these characteristics is equivalent to the natural radiation which we receive in the course of a few days.

We have to understand that the X-ray guarantees us the more precise diagnosis, which in return gives more opportunities to receive a correct treatment for a disease or ailment in question.

Therefore, we can conclude that X-rays are quite safe for the patient and that the benefits of any radiological study will always exceed the risk of these small doses of radiation: this is the principle of justification laid down in the legislation and on which any diagnostic test should be based.

What changes will occur concerning the information that will be offered to the patient?

There is already a draft royal decree on medical ionising radiation planned for this year. The text updates the national legislation on Directive 2013/59/Euratom replacing Royal Decree 815/2001 of 13 July concerning the use of ionising radiation in the field of medicine.

It proposes stricter requirements regarding the information to be provided to patients, the recording and reporting of doses of medical-radiological procedures, the use of reference levels for diagnosis and the availability of dose indicator devices.

With all this mentioned, we can see that we are already making significant progress for the patients of the 21st century, who will be progressively more informed about the treatments and be more aware of their environment.  Such a sign of progress implies advances when it comes to diagnosis, as well as more information about the medical acts and the risks to which we may be exposed.

An important fact when it comes to providing information is that it must be written in a clear and understandable manner, not causing further doubts and queries. Therefore, it would be good if we all knew something about the radiation and its use, the advances it has made in medical technology and its benefits that millions of people worldwide have enjoyed.

Breast Cancer Treatments: Mastectomy

Posted by Xanit Internacional Xanit Internacional | Posted in women's health | Posted on17-10-2018

This week is World Breast Cancer Day, and we wanted to talk to Dr Fran Fernandez, Head of the Breast Unit at Vithas Xanit International Hospital, about one of the most common treatments for breast cancer – mastectomy. 

Mastectomy 

We treat cancer in several ways, but one of the most common methods is surgery. There are two types of operation depending on the stage of the disease. If the cancer is detectedin the early stages, the usual way forward would be the conservative surgery, which consists of removing the section of the breast with a tumour in it. In the caseof more advanced stages, the method we use is a mastectomy, which is the surgical act of completely removing a breast.

According to the protocols of preventive diagnosis of breast cancer, the percentage of mastectomy procedures is decreasing thanks to early detection through breast self-examination and radiological tests, depending on patient’s age, past medical and family history. Also, mastectomy can be avoided in those cases when we indicate chemotherapy treatments before the surgery. Experts recommend exercising regularly and eating a healthy diet to reduce risk factors, for a healthy body is more difficult to get sick.

Treatment 

The duration of breast cancer treatment can vary depending on the diagnosisand can range from simple surgery without further treatment, or those cases when the procedure can be prolongedfor up to 5 years. A good family environment is also necessary for a patient’s recovery. It is vital that the patient isadequately informedof the circumstances of their case and the options available. Some patients require the help of a psychologist and support groups, which can also play a vital role throughout the treatment. Besides, the patient can and should perform a physical exerciseto return to normal.

Risks 

Body imageis a critical psychosocial issue for post-mastectomy patients as they often undergosignificant changesto appearance and functioning. Changes in body image not rarely affect patient’s both intimate and social relationships. Other alterations that may occur are of sexual nature, chronic pain, lymphoedema or psychological sequelae,among others. We are fully aware of the impact post-mastectomy alterations may have on a patient, and we always advise our patients to be psychologically predisposed to overcome obstacles.

Fortunately, major, lethal complications are becoming less frequent. The current survival rate for breast cancer is nearly 85%, but we must continue to insist on early detection and new clinical trials toreduce the remaining 15%.

Cardiovascular diseases are the leading cause of death in Spain

Did you know that cardiovascular diseases are the leading cause of death in Spain? Today, Dr Gomez Doblas talks to us about these pathologies and their risk factors, offering us some advice on taking care of our heart.

Cardiovascular diseases represent 29.66% of the total number of deaths in our country, which places them above cancer (27.86%) and pathologies of the respiratory system (11.08%). Fortunately, they are also one of the illnesses that can be prevented the most, mainly by adopting healthy lifestyle habits.

Many risk factors can trigger cardiovascular related pathologies, such as obesity, arterial hypertension, cholesterol, diabetes, smoking, inadequate nutrition or sedentary lifestyle. Their prevention with multi-factorial strategies has shown that the development of cardiovascular illnesses we can avoid in 30% of cases. With that in mind, we would like to take the opportunity of the fact that World Heart Day has recently been celebrated to make particular emphasis on the importance of prevention since by following a few simple tips we can keep our heart healthy and prevent cardiovascular pathologies.

 

Some advice on taking care of our heart:

  • Doing sport regularly:Sport is one of the best methods to prevent health problems. Exercising reduces the risk of heart diseases and all types of cardiovascular illnesses. The practice of moderate exercise or sports activity along with the monitoring of other health habits has immediate consequences in the reduction of risk factors such as diabetes, arterial hypertension, arteriosclerosis, obesity and hypercholesterolemia. Sport lowers cholesterol levels in general and raises HDL (good cholesterol). It also benefits patients with type II diabetes by increasing the sensitivity of cells to insulin.

Besides, physical exercise improves the organic capacity of the heart, reducing our need for oxygen and lowering our blood pressure, so that we require the medication less and, at the same time, we improve the quality of our life.

Aerobic exercise is recommended between three and five times a week in sessions of no less than 30 minutes, controlling the heart rate to keep it within levels of moderate intensity. The most recommended physical activities are brisk walking or running at a gentle pace, bicycling, and swimming. We recommend that the intensity of these exercises should be moderate, involving and moving large muscle groups for the maximum benefits.

  • Following a healthy diet: A low consumption of dairy products is recommended (between 2-4 portions a day of skimmed or semi-skimmed products), using more olive oil as the primary source of fat, eating meat and meat products in small quantities, increasing, on the contrary, the consumption of fish and legumes as the main source of protein. It is also recommended to eat plenty of cereals (4-6 servings a day in the form of bread, rice, pasta – ), as well as fruits and vegetables. The consumption of salt and products rich in sugars must also be limited and, of course, we must not forget to drink at least 2 litres of water a day.

Performing sports will also help us in this task, allowing better control of caloric intake, which translates into a decrease in being overweight, producing a significant improvement in the quality of life.

Resolution on healthy lifestyle habits: Quitting negative habits such as smoking and reducing alcohol intake can also help us take care of our heart. Only by quitting smoking, for example, we can significantly reduce the risk of heart attacks and strokes.

  • Monitoring our heart regularly with medical check-ups:There is no specific “optimal” age to start caring for our heart. Even if we do not present any symptoms of cardiovascular diseases, we are still recommended to have a medical check-up of the heart from the age of 45-50. Furthermore, it is advisable to repeat the test every five years. Also, if we practice sports on a regular basis, we should perform the check-up a few years earlier, at the age of 40-45, and repeat it with the same frequency: a check-up every five years even if there are no symptoms. Professional athletes and people who regularly engage in high-intensity exercise should have a sports cardiovascular check-up.

Non-alcoholic fatty liver

Posted by Xanit Internacional Xanit Internacional | Posted in Various, Xanit salud | Posted on20-09-2018

Fatty liver occurs when there is an accumulation inside its cells of small droplets containing different types of fats(mainly fatty acids and triglyceride). It is a widespread pathology in the western world and in Spain, where it affects 25% of the population.

It can occurafter taking certain drugs, in people who consume significant amounts of alcohol (in which cases we call it fatty liver or alcoholic steatosis), but also in people who do not consume drugs or significant amounts of alcohol. It is in these latter cases when we use the term FATTY LIVER OR NON-ALCOHOLIC STEATOSIS.

 

 The causes are multiple

Although genetic predispositionis one of the causes of this pathology, it is not the only one, since other factors also play a role, among which we can highlight overweight and obesity, which fundamentally affects the increase in the abdominal perimeter. Fatty liver is a pathology that also develops especially in diabetic patients(more than half of the patientsdiagnosed with diabetes develop a fatty liver), and in patients with increased levels of fats such as cholesterol and triglyceride in the blood. When all these factors coincide, we say that the patient has metabolicsyndrome. Metabolic syndrome implies that a series of alterations occur in some of the proteins that regulate the formation and elimination of fats inside the liver cell, causing fat to accumulate inside small vacuoles or fat droplets. These gradually increase in size until they cause the rupture of the hepatic cell, and in affected patients it is reflected in frequently altered “liver transaminase” (enzymes found inside the hepatic cell and which pass into the blood, elevating their levels with the ruptures of the hepatocyte). Thisis often the only sign of the disease, asthepatient usually has no or very mild symptoms.

 The Risks

Most patients with non-alcoholic fatty liver have mild liver inflammation, and the likelihood of long-term severe liver lesions or complications in liver function is low. However,in 20% of cases, the damage caused to the liver is significant, and the patients may develop cirrhosis, thereby increasing the risk of liver failure or complications such as liver tumours.But this isn’t the only complication of fatty liver. It is knownthat the presence of significant hepatic steatosis is also an indirect cardiovascular risk,with these patients having a higher incidence of cardiac and vascular complications.The incidence of other tumours outside the liver is also higher among patients with the non-alcoholic fatty liver.

Diagnosis

Diagnosing non-alcoholic fatty liver in patients with the suspectedliver disease is a challenge. The study of these patients, at the first instance, has to rule out the existence of other coinciding liver pathologies,such as hepatitis or alcohol abuse, as well as those that could worsen the prognosis of the patients. It is also important to try to identify those cases when a patient has a fatty liver with more pronounced inflammation and is, therefore, more likely to have complications in the future. Detection of such cases allows special surveillance for this high-risk subgroup, as well as the implementation of a therapeutic plan based on the combination of a diet and physical exercise to reduce the overweight and insulin resistance usually present in diagnosed patients. Besides, the use of some drugsin certain circumstances can also help control and improve the disease and its associated comorbidities.

Back pain at work and school

Posted by Xanit Internacional Xanit Internacional | Posted in Various | Posted on06-09-2018

Some pains arevery familiar to all of us. One of them is back pain. This ailment is, for various reasons, one of the most frequent reasons for medical consultations both in adults and children, but why? As we approach back-to-schooland back-to-work time of the year, what recommendations can we use to prevent and alleviate these annoying pains?

Dr Antonio Narvaez, Head of the Traumatology Department at the Vithas Xanit International Hospital in Benalmádena tells us why our back hurts, and also offers us some advice on how to address this problem.

Back pain is very common among the general population and is largely due to bad postural habits in a spine with poorly exercised back musculature.

Back pain problems can vary according to patient’s age – in children they may be due to problems of scoliosis or small fractures in some parts of the vertebrae.In middle age patients, the back problems are mainly due to pathological intervertebral discsthat can trigger herniated discs and in elderly patients,the back pain is usually due toproblems in disc dehydration, resulting in nerve compressions and instabilities in the spine. Whetherwe are dealing with cervical or lumbar pain, usually in almost all cases the origin of the pain is in disc pathologies which are a commondenominator.

Recommendations for back-to-school… and work

Oftenwhen children complain of back pain at school, the main recommendation is to maintain good postures while studying, avoid carrying heavy loads on the back and do physical exercise.

For adults with back problems at work, the recommendations are similar, fundamentally postural changes and building muscle strength and flexibility.

We might avoid back pain or prevent its recurrence by improving our physical condition and learning and practisingproper body mechanics.

If we analyse the way we should hold our body, the correctposture is sitting with the back upright, avoiding flexure.We should choose a seat with good lower back support, armrests and a swivel base.

We must avoid, whenever possible, carrying the heavy load on our back, movements that twist or strainour back and avoid heavy lifting. Our spinal column is not designed to carry heavy loads. We should be using alternative weight-bearing systems so that our vertebrae and discs do not have to sufferthe weight, thus helping us maintain the health of our back.

Well-practisedsportsactivity can also help us to prevent back pain, because the strengthenmusculature stabilisesthe spine. However, it is important that we carry out the physical activity in a controlled way and whenever possible to be monitored by a good instructor, and to avoid exercises with heavy weights without being supervised.

We cantake measures to prevent or relieve most back pain episodes simply by following the recommendations given by the specialists in this field. However, in the case of severe pain, or development of further complications and symptoms, we should seek medicalhelp.

Vitamin D: A source of health for our body (Part II)

Posted by Xanit Internacional Xanit Internacional | Posted in Various, Xanit salud | Posted on09-07-2018

There is a common belief that there is only one type of Vitamin D. In fact, there are several. Of these, those that interest us for our health are D2 and D3.

Vitamin D2 is a prohormone that is mainly found in fungi as of ergosterol molecules in combination with ultraviolet radiation from the sun. Some plants contaminated with fungi are capable of having Vitamin D2 in their composition.

On the other hand, Vitamin D3 is generated by plants in their normal state and by animal cholesterol molecules together with the interaction of ultraviolet light.

 

Vitamin D3 or D2: which one is better?

Until recently it was believed that both forms of Vitamin D were similar. However, clinical trials have shown that D3 is much more beneficial.

Clinical studies have revealed that Vitamin D3 is much more effective than D2. People who take Vitamin D3 get twice the level of Vitamin D in their body, compared to those who take Vitamin D2.

 

Fortification of food with Vitamin D

In recent years, many retailers in the food industry have enriched their products with Vitamin D2 in the belief that it meets the daily needs of consumers. However, clinical studies have shown that Vitamin D3 is much more effective than Vitamin D2.

People who eat foods that contain Vitamin D3, such as fish, eggs, or Vitamin D3 supplements, increase their Vitamin D levels much more than people who eat foods that contain Vitamin D2, such as bread or milk enriched with Vitamin D2 or dietary supplements of Vitamin D2.

 

Curiosities of Vitamin D

It has been proventhat 90% of Vitamin D is produced directly in the body using UVB radiation from the sun and that only the remaining 10% is acquiredthrough diet.

The farther we live from the equator, the darker skin we have, the more overweight we are and the less exposedwe are to the sun, in those cases we should be taking more Vitamin D supplements, either through food or as a dietary supplement, to achieve healthy blood levels of this vitamin.

Walking for 20 minutes a day in winter may be well-intentioned advice, but it is not enough to synthesise the amount of Vitamin D needed for our body.

Vitamin D has an antimicrobial effect by enhancing the immune system as well as anti-inflammatory properties. Thus, it plays a decisive role in preventing acute or chronic inflammation and accelerating the healing process.

Vitamin D is used to prevent Alzheimer’s, as it facilitates communication between nerve cells and therefore, protects them from long-term death.

Russian and German athletes have used the benefits of the sun to improve physical performance for the past 30-40 years. They knew that Vitamin D promotes muscle efficiency and endurance, and, therefore, helps improve sports performance.

Clinical studies show that Vitamin D is essential for maintaining optimal conditions of our brain and state of mind and that its deficiency can lead to depression.

With age, the body gradually loses the ability to synthesise Vitamin D through sunlight. At the same time, the age increases the body’s need for Vitamin D.

Antidepressants, anticoagulants, corticosteroids, and medications to treat peptic ulcer and epilepsy may inhibit the absorption of the Vitamin D we take through our diet. Also, people with heavy alcohol consumption may be at increased risk of Vitamin D deficiency. They are advisedto take Vitamin D as a supplement.

Vegans, in particular, are at higher risk of Vitamin D deficiency, as this vitamin is usually contained mainly in foods of animal origin. However, mushrooms and avocados also contain Vitamin D2 and a precursor of Vitamin D3.

Sunscreens prevent the synthesis of Vitamin D. For that reason, to get our body to generate Vitamin D, we should walk for 10-20 minutes without sun protection and then apply the sunscreen.

However, the sun exposure poses a dilemma, while it may be useful for producing Vitamin D, which protects us against certain types of cancer, osteoporosis, Alzheimer’s and other diseases, it is worth considering whether it can cause skin cancer.
