Swyer-James-MacLeod syndrome. (1/9)
Swyer-James-MacLeod syndrome is a rare complication of respiratory tract infection occurring in early childhood. We report two children with chronic cough and recurrent wheezing who fulfilled the diagnostic criteria for this disorder: 1) Unilateral loss of lung volume with hyperlucency on chest x-ray. 2) Unilateral reduction in vascularity on CT scan of the chest. 3) Unilateral loss of perfusion on Technetium 99c lung scan.

Disproportionate emphysematous involvement of the lung bases, compared with the apices, sometimes called basilar hyperlucency, is an unusual radiographic pattern that has been reported primarily in patients with alpha-1 antitrypsin deficiency, but also in individuals with emphysema caused by intravenous injection of methylphenidate. We present a patient with emphysema associated with hypocomplementemic urticarial vasculitis syndrome and whose chest radiograph demonstrated basilar hyperlucency. To the extent that basilar hyperlucency has not been well recognized as a feature of hypocomplementemic urticarial vasculitis syndrome, this report extends the spectrum of causes of this unusual radiographic pattern of emphysema.

(+info)Regression of giant bullous emphysema. (4/9)
Spontaneous resolution of bulla associated with infection or tumor is occasionally observed. However, resolution of progressively enlarging giant bullous emphysema (GBE) after medical therapy has not been reported. A 51-year-old man smoker with GBE on the right lung was referred to Samsung Medical Center for the consideration of bullectomy. A review of his medical records revealed that right-side bullous emphysema had been detected 4 years previously and it had progressively enlarged with a concomitant deterioration of lung function. Although he had a history of chronic asthma, he had never been treated on a regular basis. After combination therapy, including regular tiopropium, a salmeterol/flucatisone inhaler, a salbutamol inhaler as needed, and oral theophylline therapy, right side bulla showed marked regression. This regression of bulla was associated with an improved forced expiratory volume in one second and normalization of residual volume. This case serves as a reminder to clinicians that medical treatment for underlying diseases should precede surgical consideration in patients with GBE.

(+info)Swyer-James syndrome with peculiar course and ipsilateral pulmonary vein defect. (6/9)
Swyer-James syndrome (SJS) is a rare disease probably resulting from bronchiolitis obliterans. The radiological findings of this entity are characterized by hyperlucent appearance of one or more lobes of a unilateral lung, decreased lung volume, diminished ipsilateral hilar shadow and hardly visible arterial structure on chest radiography. We report a 50-year-old patient, who had unilateral right lower lung hyperlucency on chest radiography. However, the patient reported a history of pulmonary atelectasis of lobus centralis dexter in the course and the corresponding affliction of ipsilateral pulmonary vein, that rendered the diagnosis more complicated. The radiological and pathological features of this syndrome, as well as differential diagnosis were also discussed.

(+info)Swyer-James-McLeod's syndrome and pneumothorax on same side: delay in chest drain removal despite full expansion. (8/9)
(+info)A hyperlucent lung on a chest X-ray or CT scan appears lighter in density compared to a normal lung, which means that it contains less solid structures such as blood vessels, pulmonary tissue, and fluid. This can be caused by various conditions such as emphysema, lung cysts, bullae, or pneumothorax, among others. It is important to note that the interpretation of medical images requires professional training and expertise.
Bronchiolitis obliterans is a medical condition characterized by the inflammation and scarring (fibrosis) of the bronchioles, which are the smallest airways in the lungs. This results in the narrowing or complete obstruction of the airways, leading to difficulty breathing and reduced lung function.
The condition is often caused by a respiratory infection, such as adenovirus or mycoplasma pneumonia, but it can also be associated with exposure to certain chemicals, drugs, or radiation therapy. In some cases, the cause may be unknown.
Symptoms of bronchiolitis obliterans include cough, shortness of breath, wheezing, and crackles heard on lung examination. Diagnosis typically involves a combination of medical history, physical exam, imaging studies (such as chest X-ray or CT scan), and pulmonary function tests. In some cases, a biopsy may be necessary to confirm the diagnosis.
Treatment for bronchiolitis obliterans is focused on managing symptoms and preventing further lung damage. This may include bronchodilators to help open up the airways, corticosteroids to reduce inflammation, and oxygen therapy to help with breathing. In severe cases, a lung transplant may be necessary.
Lung transplantation is a surgical procedure where one or both diseased lungs are removed and replaced with healthy lungs from a deceased donor. It is typically considered as a treatment option for patients with end-stage lung diseases, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, idiopathic pulmonary fibrosis, and alpha-1 antitrypsin deficiency, who have exhausted all other medical treatments and continue to suffer from severe respiratory failure.
The procedure involves several steps, including evaluating the patient's eligibility for transplantation, matching the donor's lung size and blood type with the recipient, and performing the surgery under general anesthesia. After the surgery, patients require close monitoring and lifelong immunosuppressive therapy to prevent rejection of the new lungs.
Lung transplantation can significantly improve the quality of life and survival rates for some patients with end-stage lung disease, but it is not without risks, including infection, bleeding, and rejection. Therefore, careful consideration and thorough evaluation are necessary before pursuing this treatment option.
Bronchiolitis is a common respiratory infection in infants and young children, typically caused by a viral infection. It is characterized by inflammation and congestion of the bronchioles (the smallest airways in the lungs), which can lead to difficulty breathing and wheezing.
The most common virus that causes bronchiolitis is respiratory syncytial virus (RSV), but other viruses such as rhinovirus, influenza, and parainfluenza can also cause the condition. Symptoms of bronchiolitis may include cough, wheezing, rapid breathing, difficulty feeding, and fatigue.
In severe cases, bronchiolitis can lead to respiratory distress and require hospitalization. Treatment typically involves supportive care, such as providing fluids and oxygen therapy, and in some cases, medications to help open the airways may be used. Prevention measures include good hand hygiene and avoiding close contact with individuals who are sick.
A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.
For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.
It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.
Heterotopic transplantation is a type of organ or tissue transplant where the graft is placed in a different location from where it normally resides while still maintaining its original site. This is often done to supplement the function of the existing organ rather than replacing it. A common example of heterotopic transplantation is a heart transplant, where the donor's heart is placed in a new location in the recipient's body, while the recipient's own heart remains in place but is typically nonfunctional. This allows for the possibility of returning the function of the recipient's heart if the transplanted organ fails.
In heterotopic kidney transplantation, the donor kidney is placed in a different location, usually in the lower abdomen, while the recipient's own kidneys are left in place. This approach can be beneficial for recipients with poor renal function or other medical conditions that make traditional kidney transplantation too risky.
Heterotopic transplantation is also used in liver transplantation, where a portion of the donor liver is placed in a different location, typically in the recipient's abdomen, while the recipient's own liver remains in place. This approach can be useful for recipients with acute liver failure or other conditions that make traditional liver transplantation too risky.
One advantage of heterotopic transplantation is that it allows for the possibility of returning the function of the recipient's organ if the transplanted organ fails, as well as reducing the risk of rejection and improving overall outcomes for the recipient. However, this approach also has some disadvantages, such as increased complexity of the surgical procedure, potential for complications related to the placement of the graft, and the need for ongoing immunosuppression therapy to prevent rejection.
Viral bronchiolitis is a common respiratory infection in infants and young children, typically caused by a viral pathogen such as the respiratory syncytial virus (RSV). The infection leads to inflammation and congestion of the small airways (bronchioles) in the lungs, resulting in symptoms like wheezing, cough, difficulty breathing, and rapid breathing.
The infection usually spreads through respiratory droplets when an infected person coughs or sneezes. The virus can also survive on surfaces for several hours, making it easy to contract the infection by touching contaminated objects and then touching the face.
Most cases of viral bronchiolitis are mild and resolve within 1-2 weeks with supportive care, including increased fluid intake, humidified air, and fever reduction. However, in severe cases or in high-risk infants (such as those born prematurely or with underlying heart or lung conditions), hospitalization may be necessary to manage complications like dehydration, respiratory distress, or oxygen deprivation.
Preventive measures include good hand hygiene, avoiding close contact with sick individuals, and ensuring that infants and young children receive appropriate vaccinations and immunizations as recommended by their healthcare provider.
Viral pneumonia is a type of pneumonia caused by viral infection. It primarily affects the upper and lower respiratory tract, leading to inflammation of the alveoli (air sacs) in the lungs. This results in symptoms such as cough, difficulty breathing, fever, fatigue, and chest pain. Common viruses that can cause pneumonia include influenza virus, respiratory syncytial virus (RSV), and adenovirus. Viral pneumonia is often milder than bacterial pneumonia but can still be serious, especially in young children, older adults, and people with weakened immune systems. Treatment typically involves supportive care, such as rest, hydration, and fever reduction, while the body fights off the virus. In some cases, antiviral medications may be used to help manage symptoms and prevent complications.
Pneumonia is an infection or inflammation of the alveoli (tiny air sacs) in one or both lungs. It's often caused by bacteria, viruses, or fungi. Accumulated pus and fluid in these air sacs make it difficult to breathe, which can lead to coughing, chest pain, fever, and difficulty breathing. The severity of symptoms can vary from mild to life-threatening, depending on the underlying cause, the patient's overall health, and age. Pneumonia is typically diagnosed through a combination of physical examination, medical history, and diagnostic tests such as chest X-rays or blood tests. Treatment usually involves antibiotics for bacterial pneumonia, antivirals for viral pneumonia, and supportive care like oxygen therapy, hydration, and rest.
Bacterial pneumonia is a type of lung infection that's caused by bacteria. It can affect people of any age, but it's more common in older adults, young children, and people with certain health conditions or weakened immune systems. The symptoms of bacterial pneumonia can vary, but they often include cough, chest pain, fever, chills, and difficulty breathing.
The most common type of bacteria that causes pneumonia is Streptococcus pneumoniae (pneumococcus). Other types of bacteria that can cause pneumonia include Haemophilus influenzae, Staphylococcus aureus, and Mycoplasma pneumoniae.
Bacterial pneumonia is usually treated with antibiotics, which are medications that kill bacteria. The specific type of antibiotic used will depend on the type of bacteria causing the infection. It's important to take all of the prescribed medication as directed, even if you start feeling better, to ensure that the infection is completely cleared and to prevent the development of antibiotic resistance.
In severe cases of bacterial pneumonia, hospitalization may be necessary for close monitoring and treatment with intravenous antibiotics and other supportive care.
Paramyxoviridae is a family of viruses that includes several important pathogens causing respiratory infections in humans and animals. According to the medical perspective, Paramyxoviridae infections refer to the diseases caused by these viruses.
Some notable human paramyxovirus infections include:
1. Respiratory Syncytial Virus (RSV) Infection: RSV is a common cause of respiratory tract infections, particularly in young children and older adults. It can lead to bronchiolitis and pneumonia, especially in infants and patients with compromised immune systems.
2. Measles (Rubeola): Measles is a highly contagious viral disease characterized by fever, cough, coryza (runny nose), conjunctivitis, and a maculopapular rash. It can lead to severe complications such as pneumonia, encephalitis, and even death, particularly in malnourished children and individuals with weakened immune systems.
3. Parainfluenza Virus Infection: Parainfluenza viruses are responsible for upper and lower respiratory tract infections, including croup, bronchitis, and pneumonia. They mainly affect young children but can also infect adults, causing mild to severe illnesses.
4. Mumps: Mumps is a contagious viral infection that primarily affects the salivary glands, causing painful swelling. It can lead to complications such as meningitis, encephalitis, deafness, and orchitis (inflammation of the testicles) in rare cases.
5. Human Metapneumovirus (HMPV) Infection: HMPV is a respiratory virus that can cause upper and lower respiratory tract infections, similar to RSV and parainfluenza viruses. It mainly affects young children and older adults, leading to bronchitis, pneumonia, and exacerbations of chronic lung diseases.
Prevention strategies for Paramyxoviridae infections include vaccination programs, practicing good personal hygiene, and implementing infection control measures in healthcare settings.
Parainfluenza Virus 1, Human (HPIV-1) is a type of respiratory virus that belongs to the family Paramyxoviridae and genus Respirovirus. It is one of the four serotypes of human parainfluenza viruses (HPIVs), which are important causes of acute respiratory infections in children, immunocompromised individuals, and the elderly.
HPIV-1 primarily infects the upper respiratory tract, causing symptoms such as cough, runny nose, sore throat, and fever. However, it can also cause lower respiratory tract infections, including bronchitis, bronchiolitis, and pneumonia, particularly in young children and infants.
HPIV-1 is transmitted through respiratory droplets or direct contact with infected individuals. The incubation period for HPIV-1 infection ranges from 2 to 7 days, after which symptoms can last for up to 10 days. There is no specific antiviral treatment available for HPIV-1 infections, and management typically involves supportive care such as hydration, fever reduction, and respiratory support if necessary.
Prevention measures include good hand hygiene, avoiding close contact with infected individuals, and practicing cough etiquette. Vaccines are not currently available for HPIV-1 infections, but research is ongoing to develop effective vaccines against these viruses.
Influenza, also known as the flu, is a highly contagious viral infection that attacks the respiratory system of humans. It is caused by influenza viruses A, B, or C and is characterized by the sudden onset of fever, chills, headache, muscle pain, sore throat, cough, runny nose, and fatigue. Influenza can lead to complications such as pneumonia, bronchitis, and ear infections, and can be particularly dangerous for young children, older adults, pregnant women, and people with weakened immune systems or chronic medical conditions. The virus is spread through respiratory droplets produced when an infected person coughs, sneezes, or talks, and can also survive on surfaces for a period of time. Influenza viruses are constantly changing, which makes it necessary to get vaccinated annually to protect against the most recent and prevalent strains.
'Influenza A Virus, H1N1 Subtype' is a specific subtype of the influenza A virus that causes flu in humans and animals. It contains certain proteins called hemagglutinin (H) and neuraminidase (N) on its surface, with this subtype specifically having H1 and N1 antigens. The H1N1 strain is well-known for causing the 2009 swine flu pandemic, which was a global outbreak of flu that resulted in significant morbidity and mortality. This subtype can also cause seasonal flu, although the severity and symptoms may vary. It is important to note that influenza viruses are constantly changing, and new strains or subtypes can emerge over time, requiring regular updates to vaccines to protect against them.
