PREIMPLANTATION GENETIC DIAGNOSIS
In recent years, developments in genetics allow genetic analysis to be carried out on embryos developed in vitro by in vitro fertilization  ethods and the placement of selected healthy embryos in the uterus of the mother before pregnancy occurs. This method is called pre- regnancy genetic diagnosis (Preimplantation Genetic Diagnosis-PGD).
​
One of the most important application areas of the PGT technique embryos that do not have a genetic disease but may not have a genetic disorder in their chromosomes.
These disorders are more common in women of advanced age (35 years and older). This situation may result in infertility as it both reduces the chance of attachment of the embryo (implantation) and may cause unwanted abortions. As a matter of fact, 40 out of every 100 pregnancies in women aged 39 and over have problems that occur due to a numerical chromosomal disorder
 
The aim of PGD is to increase implantation rates, reduce spontaneous abortions and increase healthy baby birth rates by selecting hromosomally normal embryos. Indeed, the miscarriage rate, which can reach up to 23 percent in normal pregnancy due to chromosomal disorders, may decrease to 9 percent after PGD.
 
Pre-pregnancy genetic diagnosis is performed by taking 1 or 2 cells from embryos developed as a result of fertilization of egg and sperm cells obtained from mother and father candidates in laboratory environment. Special methods called Fluorescence In Situ Hybridization (FISH), Microarray-based comparative genomic hybridization (aCGH) or Polymerase Chain Reaction (PCR) are used for genetic diagnosis. Diagnosis of numerical chromosomal disorders such as monosomy or trisomy (Down syndrome and other trisomies) and single gene diseases (such as hemophilia, Mediterranean anemia, cystic fibrosis, muscular dystrophies) in the baby to be born is possible with PGD. Thus, healthy babies are born by transferring disease-free, healthy embryos to the expectant mother.
 
DIAGNOSIS BEFORE PREGNANCY
 
  • In couples with a genetic or hereditary disease carrier,
  • In couples who have a child or children with a previous genetic disease,
  • For the purpose of HLA genotyping (tissue typing),
  • In the identification of diseases showing genetic predisposition (tendency)
  • Women in the advanced age group (37 years and over) who have been accepted for assisted reproductive techniques,
  • In couples with recurrent early pregnancy miscarriages,
  • In couples who could not achieve pregnancy with assisted reproductive techniques despite multiple applications or who lost their pregnancy due to miscarriage,
  • It is applied in cases of chromosomal disorders or genetic diseases associated with severe male infertility.
 
HOW IS THE PGT TEST DONE?
 
  • Whether the patient is suitable for PGD is evaluated by the reproductive health specialist, genetic counselor and the doctor of the related disease.
  • The couple is prepared for the IVF procedure.
  • The egg taken from the mother is fertilized in the laboratory with the sperm taken from the father.
  • 1-2 blastomere cells are removed from the obtained embryo by biopsy by embryologists
  • Cells obtained by biopsy are prepared and tested according to the method to be applied.
  • Embryos with genetic diseases or chromosomal disorders are selected and discarded and healthy embryos are transferred to the mothers womb.

Neurosurgery is a medical specialty focused on the surgical treatment of disorders related to the brain, spine, and nervous system. It involves both the diagnosis and the treatment of conditions that affect the central nervous system (CNS) and peripheral nervous system (PNS).

Here are some key areas within neurosurgery:

  1. Brain Surgery: This includes procedures to treat brain tumors, traumatic brain injuries, aneurysms, and neurological disorders like epilepsy and Parkinson's disease. Neurosurgeons may also perform surgeries for congenital abnormalities or infections of the brain.

  2. Spinal Surgery: Neurosurgeons often address spinal issues such as herniated discs, spinal stenosis, and spinal cord injuries. They may also perform surgery for scoliosis or other deformities of the spine.

  3. Peripheral Nerve Surgery: This involves the surgical treatment of nerve injuries, entrapments, and diseases affecting the peripheral nervous system, like carpal tunnel syndrome.

Neurosurgery can range from minimally invasive procedures using advanced technologies to complex open surgeries that require detailed precision. It is closely related to other specialties such as neurology, radiology, and rehabilitation medicine.

“Ovarian hyperstimulation syndrome”, also known as Ovarian Hyperstimulation Syndrome (OHSS), in the most basic way; It can be explained as a reaction to the hormones given to women for the development of the ovaries. During IVF treatment, women are given hormone drugs to stimulate and support egg development. When these hormone drugs stimulate the ovaries more than necessary, the syndrome of overstimulation of the ovaries occurs.


How Ovaries Stimulation Happens?

Ovarian hyperstimulation syndrome (OHSS) is an undesirable consequence of IVF treatment. Although the aim of IVF treatment is to develop a large number of eggs, OHSS may occur if more than a certain number of eggs develop.

Women with polycystic ovary syndrome are much more likely to have ovarian overstimulation syndrome. Excessive response to the drugs given to stimulate the ovaries prepares the ground for encountering this syndrome. During the stimulation of the ovaries, there is a fine line between stimulating the desired number of eggs and over-stimulating the ovaries. It is not always possible to determine this point clearly. When there is overstimulation, reducing the dose of ovarian stimulating drugs and not giving the drug for a day or more, if needed, can prevent the excessive rise of estrogen.


Symptoms of ovarian hyperstimulation syndrome can be mild, moderate or severe. These symptoms are;

-Increased ovarian size

- Abdominal pain, bloating, shortness of breath, decreased urination

-Fluid accumulation in the abdominal cavity

-Coagulation disorders

It can be seen as fluid collection in the chest cavity. It is extremely important to follow these situations closely and to get medical support when necessary.


How is Ovarian Overstimulation Syndrome Treated?

OHSS treatment is carried out to relieve the expectant mother, reduce ovarian activity and prevent complications. However, OHSS can be performed in two different ways as drug and surgical treatment. In mild cases, no additional treatment is required other than outpatient follow-up and severe physical activity restriction, and the patient can usually recover in 10-14 days. Moderate and severe cases may require hospitalization and treatment. In most cases, women who have had OHSS can continue IVF. It is still possible to become pregnant despite OHSS, but these symptoms may worsen if pregnancy occurs. In this case, the patient is followed closely under the supervision of a doctor.

In some cases, it is not enough if only the reproductive system is healthy for pregnancy to occur. Along with the reproductive system, it is extremely important for the pregnancy process that many factors work in harmony with each other. Depending on the factors that affect the process, pregnancy may not occur in people. This condition can also be observed if the person has already become pregnant or had a healthy birth.
Infertility, which occurs as a result of a couple having regular sexual intercourse for 12 months and not being able to get pregnant even though they are not using a method of protection, can be seen in two different ways. Never before pregnancy occurs when primary infertility; a live birth or not, regardless of if at least one pregnancy occurred, secondary (secondary) infertility is defined as.
You can continue reading our article about what is secondary infertility, what are its causes, important risk factors and treatment topics.

Causes of Secondary Infertility

Best Sleeping Practices for Newborns: How to Ensure Safe Sleep

Newborns spend most of their early days sleeping, making it essential for parents to create a safe and comfortable sleep environment. Following best sleep practices not only helps your baby rest better but also reduces the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related concerns. Here’s a comprehensive guide to ensuring safe sleep for your newborn.

1. Follow the "Back to Sleep" Rule

One of the most crucial sleep safety tips is placing your baby on their back to sleep, both for naps and nighttime rest. This reduces the risk of SIDS significantly. Avoid placing your baby on their stomach or side, as these positions can obstruct breathing.

2. Choose a Safe Sleeping Surface

  • Use a firm, flat mattress covered with a fitted sheet in a safety-approved crib or bassinet.

  • Avoid placing soft bedding, pillows, stuffed animals, or crib bumpers in the sleeping area, as these increase the risk of suffocation.

  • Do not let your baby sleep on couches, armchairs, or adult beds unattended.

3. Keep the Crib in Your Room

  • The safest place for a newborn to sleep is in a crib or bassinet in the same room as the parents (but not in the same bed) for at least the first six months.

  • Room-sharing reduces the risk of SIDS and makes nighttime feedings easier.

4. Regulate Room Temperature

  • Keep the room at a comfortable temperature (between 20-22°C or 68-72°F).

  • Overheating increases SIDS risk, so dress your baby in light, breathable layers rather than heavy blankets.

5. Avoid Loose Blankets – Use a Sleep Sack

  • Instead of blankets, use a sleep sack or swaddle to keep your baby warm.

  • If swaddling, ensure the baby’s hips can move freely to prevent hip dysplasia.

6. Follow a Consistent Sleep Routine

  • Establish a simple bedtime routine with activities like bathing, feeding, gentle rocking, or soft lullabies to help your baby recognize sleep time.

  • Newborns thrive on predictability, so keeping a consistent routine helps improve sleep quality.

7. Offer a Pacifier at Bedtime

  • Giving your baby a pacifier during sleep times may help reduce SIDS risk.

  • If breastfeeding, wait 3-4 weeks until breastfeeding is well established before introducing a pacifier.

8. Avoid Smoking and Exposure to Secondhand Smoke

  • Secondhand smoke increases the risk of SIDS and other respiratory issues.

  • Keep your baby in a smoke-free environment at all times.

9. Be Mindful of Daytime and Nighttime Sleep Differences

  • Encourage daytime alertness by exposing your baby to natural light and engaging in play.

  • Keep nighttime interactions quiet and calm, with dim lighting, to reinforce that night is for sleep.

10. Know When to Seek Medical Advice

  • If your baby struggles to breathe, has irregular sleep patterns, or seems excessively fussy, consult a pediatrician.

  • Regular check-ups ensure your newborn is developing healthily and sleeping well.

Conclusion

Creating a safe sleep environment for your newborn is essential for their well-being and your peace of mind. By following these best sleeping practices, you can help your baby sleep soundly and safely. If you have concerns about your baby's sleep habits, always consult your pediatrician for guidance.
