With the beautiful autumn days and colors, upper respiratory tract infections or acute respiratory viral infections (ARVI) become more frequent. People often call them seasonal colds. Let’s understand together how children get infected with these viruses and what should be done to prevent them. Upper respiratory tract infections are seasonal viral diseases transmitted by airborne droplets (coughing/sneezing on each other, touching household items/toys of an infected person, using the same dishes). These infections are self-limiting and usually start in autumn, continuing until late spring (or, as they say, along with the school year). The main symptoms are: • Sudden and frequent fever (38°C and above) • Chills, shivering • Headache, muscle pain, body aches • Sore throat • Cough • Runny nose • Sometimes vomiting or diarrhea Respiratory viruses mainly affect the upper respiratory tract — the nasopharynx, throat, and trachea — but sometimes can also involve the bronchi. The illness usually lasts up to one week, sometimes a little longer. What to do in case of viral infection When a child gets infected, the main goal is to ease their condition and prevent complications. • Offer plenty of fluids (water). • Clean the nasal passages with saline solution (NaCl 0.9%) or sea salt sprays. • In case of fever, give Acetaminophen (Paracetamol) or Ibuprofen (Nurofen) in syrup, suppository, or tablet form — according to age and weight, and only as prescribed by a pediatrician. • Ensure constant room ventilation and maintain air humidity. • In case of cough, honey can be useful for children over 1 year old (it is not allowed for younger ones due to the risk of botulism). Important facts about medication Ibuprofen should not be used for dehydrated or persistently vomiting children. Aspirin is prohibited under the age of 12. Antiviral suppositories (Viferon, Genferon) have no proven effectiveness and are often confused with fever reducers, which can be dangerous during high fever. The only antiviral medication with proven effect is Oseltamivir (Tamiflu), used in confirmed influenza cases, starting from the first day of illness and only by pediatric prescription. When to seek immediate medical attention If you notice that your child has: • Frequent or labored breathing • Cyanotic (bluish) lips • Retractions between the ribs while breathing • Chest pain • Severe muscle pain causing refusal to walk • Signs of dehydration (no urination for 8 hours or more, dry mouth, crying without tears) • Weakness or lack of response • Convulsions • Persistent high fever (40°C and above) • Age under 3 months • Worsening or recurrence of symptoms after a few days • Presence or exacerbation of chronic diseases (e.g. diabetes, asthma) To prevent respiratory viral infections, it is important to teach children to wash their hands frequently (especially after returning home), eat healthy and balanced meals (with plenty of fruits and vegetables), avoid contact with sick individuals, and receive all vaccinations according to the national immunization schedule (including the seasonal flu vaccine). Thus, follow and teach your children to maintain hygiene rules, eat healthy and varied food, have sufficient physical activity, and good sleep.

Cough is a natural protective reflex of the body and plays an important role in the innate immunity of the respiratory system. It helps clear mucus, microorganisms, and irritants from the airways. The mechanism of coughing includes three phases: inhalation, compression, and exhalation. The effectiveness of a cough depends on several factors: • the proper width of the airways (narrowing reduces its efficiency), • the properties of mucus, • and the strength of the respiratory muscles. It’s very important not to suppress the cough reflex without identifying and treating the underlying cause. Cough occurs in almost all children, including premature infants (about 10% of babies born at 27 weeks and up to 90% of full-term newborns). It is one of the main clinical signs of respiratory diseases, but it can also appear in non-respiratory conditions. Types of Cough • Normal (expected) — during viral infections • Specific — with sudden shortness of breath, recurrent pneumonia, neuromuscular disorders, or chest/jaw anomalies • Nonspecific — dry cough without an identified respiratory disease (may resolve spontaneously) Cough is also classified by: 1. Cause 2. Duration: Acute — up to 4 weeks Chronic — longer than 4 weeks 3. Nature: Dry or wet (productive) Acute Cough In children, acute cough is most often associated with viral infections of the upper respiratory tract. It usually resolves on its own after the infection and rarely requires further testing. If the cough is persistent, lasts more than 4 weeks, or is accompanied by other concerning symptoms, a doctor’s visit is necessary. Acute cough may also develop after foreign body aspiration, especially in children aged 3–5 years, who tend to put small objects in their mouths. This situation requires immediate medical attention. Acute cough can indicate both respiratory and non-respiratory diseases. Respiratory causes include: nasopharyngitis, sinusitis, false croup, tracheitis, bronchitis, pneumonia, and asthma. Non-respiratory causes include neurological problems, congenital heart defects, and others. The most common cause of acute cough is the common cold, accompanied by sneezing, fever, runny or blocked nose, headache, and sore throat. These are usually self-limiting viral infections that don’t require antibiotics. However, if the child breathes rapidly, has a persistent fever, weakness, or refuses fluids — medical evaluation is necessary. Chronic Cough Chronic cough lasts more than 4 weeks and may be accompanied by wheezing, burning, breathing difficulty, nasal congestion, or hoarseness. You should see a doctor if your child has: • frequent, persistent cough, • barking or nighttime cough, • wheezing or noisy breathing, • productive cough with mucus, • rough or hoarse-sounding cough. Chronic cough may occur in both younger and older children. • In children under 5 years old, it can be caused by infections, asthma, foreign body aspiration, passive smoking, or congenital abnormalities. • In children over 5 years old, causes include asthma, prolonged bacterial bronchitis, allergies, long-term use of nasal drops, and passive smoking. What to Do During autumn, when viral infections are more common, it’s important to pay close attention to cough symptoms and seek timely care. If your child has a cough, don’t wait for it to pass on its own. Consult a pediatrician.

The duplex examination is a modern ultrasound method that allows for the assessment of blood circulation in the lower limbs and the structural condition of the vessels. Through this technique, it is possible to evaluate vessel patency, the degree of narrowing, the state of the vessel wall and lumen, measure vessel diameter, assess blood flow velocity, and detect deformations or the presence of atherosclerotic plaques. Advantages of Duplex Examination • Painless and short (takes about 15–30 minutes) • Absolutely safe (can be performed even during pregnancy) • Affordable and highly informative • No age or gender limitations When the Examination Is Recommended • Swelling of the legs • Feeling of heaviness or discomfort in the lower limbs • Pain or muscle tension during walking (after 10, 50, or 100 meters) • Visible varicose veins • Changes in skin color • Numbness • Vascular “stars” or pronounced subcutaneous vein changes • Diabetes mellitus People at Risk • Those with arterial hypertension • Individuals with cardiovascular diseases • People with obesity • Patients with atherosclerosis or high cholesterol • Individuals with diabetes mellitus • Smokers Duplex examination plays an important role in the early diagnosis of vascular diseases. It allows timely detection of circulation disorders, helps prescribe effective treatment, and prevents the development of complications.

An endometrial polyp is a benign growth of the uterine cavity lining. The incidence increases during reproductive age and the perimenopausal period. Main factors contributing to the development of uterine polyps 1. Hormonal imbalance Increased estrogen levels and decreased progesterone levels lead to endometrial hyperplasia (excessive thickening), which contributes to polyp formation. 2. Inflammatory and infectious processes Chronic inflammations, such as endometritis, and infections, including sexually transmitted diseases, can disrupt endometrial cell processes and promote abnormal growth. 3. Mechanical injury Damage to the uterine lining caused by miscarriages or diagnostic curettage may lead to the development of polyps. 4. Endocrine diseases Women suffering from type 2 diabetes, polycystic ovary syndrome (PCOS), or thyroid dysfunction are at higher risk of developing polyps. 5. Excess weight and sedentary lifestyle Obesity and low physical activity affect hormonal balance, which in turn increases the risk of polyp formation. 6. Genetic predisposition Hereditary susceptibility to gynecological diseases and reproductive system tumors may also be a risk factor. 7. Early menarche or late menopause Menstrual onset before age 12 or menopause after the typical age is associated with elevated estrogen levels, which raises the risk of polyp development. Symptoms In many cases, polyps may be asymptomatic, but sometimes the following symptoms occur: • Irregular or intermenstrual bleeding • Heavy menstrual bleeding • Lower abdominal pain • Infertility Diagnosis A polyp can be detected by: • Ultrasound examination (sonography) • Hysterosonography • Hysteroscopy (considered the “gold standard”) Treatment Polyp removal is mainly performed by hysteroscopy, which serves both diagnostic and therapeutic purposes. The removed tissue must be sent for histopathological examination to exclude the presence of malignant cells.Prevention and Monitoring • Regular gynecological examinations • Sonography for early detection • Regulation of hormonal balance Uterine polyps are generally benign and treatable. Timely detection and proper management are crucial for maintaining both women’s health and reproductive function.
