Poland Syndrome is a rare condition that affects the development of one side of the chest and hand. It is named after Sir Alfred Poland, a British surgeon who first described the condition in 1841. Poland Syndrome is characterized by the absence or underdevelopment of muscles on one side of the chest, which gives the affected side a flattened or concave appearance. This abnormality can also result in the absence or underdevelopment of the breast, nipple, and axilla (armpit).

In addition to the chest abnormalities, individuals with Poland Syndrome may also have hand anomalies, such as syndactyly (webbing) or underdeveloped fingers. The severity and combination of symptoms can vary widely between affected individuals.

The exact causes of Poland Syndrome are still not completely understood, but it is believed to be a combination of genetic and environmental factors. Some researchers have suggested that disruption of blood flow during embryonic development may contribute to the condition. There is evidence of familial inheritance in some cases, and certain genes have been implicated, although further research is needed to fully understand their role.

This condition is considered rare, with an estimated frequency of 1 in 20,000 live births. It affects males and females equally. The diagnosis of Poland Syndrome is typically made based on physical examination, medical history, and imaging studies. Treatment options vary depending on the severity of symptoms and may include surgical interventions to improve the appearance and function of the affected chest and hand.

For more information about Poland Syndrome, including references, articles, and additional resources, the OMIM database and PubMed can be valuable sources of scientific literature and support. There are also advocacy and support groups that provide information and resources for patients and their families.

Frequency

The frequency of Poland syndrome varies depending on the study and the population being assessed. According to research published in scientific journals and databases such as PubMed, the estimated frequency of Poland syndrome is 1 in every 20,000 live births.

Nearly 60% of Americans surveyed support a Medicare for All program, according to Business Insider. Those in favor of Medicare for All include 75% of Democrats, 58% of registered Independents and 36% of Republicans, though Republican support jumps up to 64% when discussing an optional expanded Medicare program, also referred to as “Medicare for Some.”

However, it is important to note that this number can vary significantly due to factors such as the inclusion criteria used, the accuracy of diagnosis, and the population being studied. Some studies have reported a higher frequency of Poland syndrome in males compared to females.

Poland syndrome is considered a rare condition, with estimates suggesting that it affects less than 1% of the population. This abnormality is characterized by the absence or underdevelopment of chest muscles (pectoralis major), usually on one side of the body, and can occasionally affect both sides. This disruption in muscle development can cause various additional abnormalities, including abnormalities of the hand (such as syndactyly) and other parts of the body.

Poland syndrome can occur sporadically, meaning that it is not inherited and occurs mainly by chance. In some cases, however, it appears to have a genetic component and can occur in families. Genetic research has identified several genes that may play a role in the development of Poland syndrome, although more research is needed to fully understand the genetic causes.

For patients and their families seeking more information on Poland syndrome, several resources are available. The Online Mendelian Inheritance in Man (OMIM) catalog provides detailed information on genetic diseases and conditions, including Poland syndrome. PubMed also offers a wealth of scientific articles and research papers on the topic, providing additional information and support.

Causes

Poland syndrome is a rare condition characterized by the absence or underdevelopment of muscles on one side of the chest, usually affecting the right side. The exact causes of Poland syndrome are not well understood, but several theories have been proposed.

• Genetic Factors: Some studies have suggested a genetic component to Poland syndrome, although the exact inheritance patterns are still unclear. The syndrome has been found to occur more frequently in certain families, suggesting a potential genetic cause.
• Embryological Abnormality: It is believed that Poland syndrome might result from a disruption in the development of the chest muscles during fetal development. This disruption could occur as a result of problems with blood flow or the development of blood vessels in the chest region.
• Syndactyly: Syndactyly, which is the fusion of two or more fingers or toes, is sometimes seen in individuals with Poland syndrome. This suggests that there may be a common genetic or developmental cause for both conditions.
• Other Causes: In addition to the above factors, other potential causes of Poland syndrome have been proposed, including hormonal influences, environmental factors, and vascular anomalies. However, more research is needed to fully understand these potential causes.

Poland syndrome is a rare condition, and there is limited information available about its causes. The Online Mendelian Inheritance in Man (OMIM) database and advocacy organizations such as the Poland Syndrome Support and Information Center provide resources and information for patients and healthcare providers interested in learning more about this condition. Scientific articles from PubMed, a public database of biomedical literature, can also be a valuable source of information on the causes of Poland syndrome.

Inheritance

Poland syndrome is a rare condition with an unknown cause. It is believed to be caused by a combination of genetic and environmental factors. The inheritance pattern of Poland syndrome is not well understood, and it does not follow a clear autosomal dominant or recessive pattern.

Several names have been proposed for Poland syndrome in the scientific literature, including Poland anomaly, Poland syndactyly, and Poland sequence. The condition is included in the Online Mendelian Inheritance In Man (OMIM) catalog as OMIM #173800.

The Center for Genetic Medicine at the Children’s National Medical Center is just one of many resources that can provide information on Poland syndrome and other rare genetic diseases. Their website offers scientific articles, information for patients and their families, and resources for advocacy.

Poland syndrome is characterized by the absence or disruption of the chest muscles on one or both sides, leading to a range of abnormalities. The most common abnormality associated with Poland syndrome is the absence or underdevelopment of the pectoralis major muscle, which gives the chest a concave appearance on the affected side.

• Less frequently, other muscles, such as the serratus anterior, may also be affected.
• Syndactyly, a condition where two or more fingers are fused together, may also be present on the affected side.
• In some cases, Poland syndrome may occur without any additional abnormalities.

The frequency of Poland syndrome is estimated to be around 1 in 20,000 births, although the exact cause and frequency may vary between populations. Without support from scientific studies and a large patient population, it is challenging to determine the exact inheritance pattern of Poland syndrome.

More research is needed to determine the genetic causes of Poland syndrome and to understand why some individuals inherit the condition while others do not. Additional information can be found in scientific articles available on PubMed and other scientific databases.
