Pectus carinatum, also known as duck breast, is a congenital malformation of the chest characterized by protrusion of the sternum and ribs. The condition results from abnormal growth of the cartilage that connects the ribs to the sternum, resulting in deformity of the chest wall. Pectus carinatum can vary in severity, from a mild form that has little or no clinical significance to significant deformities that can affect pulmonary and cardiovascular function. The condition can lead to social and psychological dysfunction in patients, especially during adolescence, when aesthetic criteria are important. Diagnosis and treatment of pectus carinatum are an important part of medical care, as it may require monitoring and surgical intervention.
History of the disease and interesting historical facts
The history of pectus carinatum is reflected in medical records dating back to ancient times. The first mentions of the condition are found in the writings of Hippocrates, who described various chest anomalies. In the Middle Ages, the condition was also taken into account by physicians, but it was not until the 19th century that pectus carinatum began to be studied more systematically. Interestingly, pectus carinatum was the subject of study by such renowned medical figures as A. M. Shevchenko, who in his writings considered not only the anatomical aspects, but also the possible psychosocial consequences of the condition. In a more modern context, thanks to advanced imaging techniques such as computed tomography, physicians can more accurately assess the degree of deformity and develop appropriate treatment approaches.
Epidemiology
According to various studies, pectus carinatum occurs in 1 in 400-1000 newborns. Statistically, this condition is more common in males, who account for about 70-80% of all cases. The pathology can also be associated with various syndromes, such as Marfan syndrome and Edwards syndrome, which further complicates the understanding of the epidemiology of pectus carinatum. The incidence may vary depending on the geographic region and ethnicity, indicating the possible influence of genetic factors. A deeper understanding of the epidemiology of pectus carinatum still requires further research, especially in the context of its consistency with other developmental anomalies.
Genetic predisposition to this disease
Today, there is an opinion about the presence of a genetic predisposition to pectus carinatum. Research shows that this disease may be associated with changes in a number of genes responsible for the development of connective tissue. In particular, changes in the FBN1, COL1A1 and COL1A2 genes have been identified in some patients. Mutations in these genes can lead to dysfunction of collagen and elastin, which in turn can contribute to abnormal formation of the chest. In addition, in some cases, hereditary transmission of the disease is observed, which requires further genetic analysis and counseling to identify risks in families.
Risk factors for the development of this disease
Risk factors associated with the development of pectus carinatum include both genetic and environmental aspects. The main risk factors include:
- Having a family history of pectus carinatum or other chest wall abnormalities.
- Genetic syndromes such as Marfan syndrome, Edwards syndrome and other connective tissue disorders.
- Environmental influences during pregnancy, including infections, toxic substances and nutritional deficiencies.
- Physical activity and chest injuries in early childhood.
- Metabolic disorders leading to disruption of the growth and development of bone and cartilage tissue.
Diagnosis of this disease
Diagnosis of pectus carinatum begins with a clinical examination, during which the doctor evaluates the severity of the chest deformity. The main symptoms include:
- A protruding chest, especially noticeable when breathing or exercising.
- Limited mobility of the chest.
- Problems with breathing and physical activity, especially in severe forms of the pathology.
To clarify the diagnosis and assess the functional state of the lungs, the following studies can be carried out:
- Chest X-ray.
- Computed tomography for a detailed study of the structure of the chest.
- Spirometry to assess lung function.
- Ultrasound examination to assess the state of the cardiovascular system.
Differential diagnosis should include conditions such as pectus excavatum and other chest wall anomalies.
Treatment
Treatment of pectus carinatum can be conservative or surgical, depending on the degree of deformity and clinical manifestations. General approaches to treatment include:
- Conservative therapy: Use of a special corset to correct the shape of the chest, which can be effective in cases of mild to moderate deformity.
- Pharmacological treatment: The use of nonsteroidal anti-inflammatory drugs to reduce pain associated with the deformity, however, specific pharmacotherapy for pectus carinatum has not been developed.
- Surgical treatment: Indicated for severe deformation that negatively affects the functions of the chest organs. There are several surgical techniques, the most common of which is the Asbi method. This method involves correction of the axial deformation of the chest using prostheses.
- Psychological support: It is important to take into account the psychological aspects of the disease, offering patients support and advice for adaptation to the social environment.
List of medications used to treat this disease
There are currently no specific medications available to treat pectus carinatum. The main medications that can be used to relieve symptoms are:
- Nonsteroidal anti-inflammatory drugs (eg, Ibuprofen)
- Muscle relaxants in the presence of muscle spasms.
- Antidepressants and anxiolytics in the presence of concomitant psychoemotional disorders.
Disease monitoring
Monitoring of patients with pectus carinatum includes regular assessment of pulmonary and cardiovascular function. Monitoring steps may include:
- Periodic radiographs to assess changes in the chest.
- Spirometry to monitor lung function.
- Assessment of general physical activity and quality of life.
- Psychological assessment to identify possible complications in psycho-emotional health.
The prognosis of the disease is generally favorable in case of timely diagnosis and intervention. However, if left untreated, serious complications such as respiratory failure or cardiovascular disorders may occur.
Age-related features of the disease
Pectus carinatum can manifest itself in any age group, but it receives the greatest attention in adolescence, when active bone growth begins. In children, this disease often manifests itself as a mild deformity, but during the period of active growth it can worsen. In adults, pectus carinatum can affect physical performance and quality of life, since the pathology can aggravate changes in respiratory function and lead to social problems.
