Introduction
There is no absolute fixed timing for surgery of sebaceous cysts. Generally, the optimal time for surgery is when the sebaceous cyst is uninfected but affects daily life or cosmetic appearance, or after an infection has been controlled. In the absence of infection, if the cyst gradually increases in size, affects local appearance, or is located in an area prone to friction causing discomfort, surgical removal at this stage allows for complete excision of the cyst.

There is no absolute fixed time for surgical removal of sebaceous cysts. Generally, the optimal timing for surgery is when the cyst shows no signs of infection but affects daily life or cosmetic appearance, or after an infection has been successfully controlled. If in doubt, it is advisable to seek medical consultation early. Specific details are as follows:

In the absence of infection, if the cyst gradually increases in size, affects local appearance, or is located in an area prone to friction causing discomfort, surgical removal at this stage allows complete excision of the cyst, reduces the risk of recurrence, and enables smoother postoperative recovery with less disruption to daily activities.

If the cyst becomes infected—manifesting as redness, swelling, pain, or pus formation—anti-infective treatment should first be administered. Surgery should be performed only after inflammation is controlled and swelling has subsided. Performing surgery at this point helps prevent the spread of infection, reduces intraoperative bleeding and postoperative complications, promotes better wound healing, and prevents recurrent inflammation.

Surgery should be carried out at a qualified medical facility. After surgery, it is important to keep the wound clean and dry, avoid contact with water and friction, follow medical instructions for dressing changes, ensure proper wound healing, and minimize the risks of infection and recurrence.

Can I take anti-inflammatory medication after undergoing bronchial balloon surgery?
If symptoms of infection such as fever, worsening cough, or production of purulent sputum occur after bronchial balloon surgery, or if tests indicate a respiratory tract infection, anti-infective treatment may be prescribed by a physician. In such cases, taking anti-inflammatory medication as directed helps control the infection, prevent the spread of inflammation, support postoperative repair of the respiratory mucosa, and reduce the risk of complications.

What should I do if there is still stabbing pain one month after surgery for a lung nodule?
One month after surgery for lung nodules, sharp pain may still persist. This can be managed through proper wound care, adjusting breathing techniques, reducing local inflammation, regulating psychological state, and planning activities appropriately. In most cases, symptoms can improve with scientific interventions. However, if the sharp pain lasts more than two weeks, worsens, or is accompanied by difficulty breathing or abnormal secretions, prompt medical attention is recommended.

Can squamous cell carcinoma of the left main bronchus be treated with surgery?
If left main bronchial squamous cell carcinoma is in the early stage, with the tumor confined to the left main bronchus without invasion of surrounding major blood vessels, the heart, or other vital organs, and there is no distant metastasis, surgical treatment is generally feasible provided that the patient has good cardiopulmonary function, no severe underlying diseases, and can tolerate surgical trauma. The surgery involves resection of the tumor and the affected bronchus, and when combined with subsequent treatments, offers the potential to control disease progression.

Can you get infected with HIV from having surgery?
Whether surgery leads to HIV infection depends on whether the medical institution is正规. Undergoing surgery at a正规 medical facility typically does not result in HIV infection; however, invasive procedures performed at unlicensed or non-compliant facilities carry a risk of infection. To avoid such risks, patients should seek care only at正规 institutions and actively cooperate with preoperative screenings. After surgery, it is important to keep the wound clean and dry, avoiding contact with water and contaminants.

Can parotid cysts be treated without surgery?
In general, whether surgery is needed for a parotid cyst depends on a comprehensive assessment of the cyst's characteristics, size, symptoms, and changes over time. It is important to maintain good oral hygiene by rinsing the mouth with warm water after meals and brushing teeth thoroughly in the morning and evening. Avoid spicy and acidic foods to reduce stimulation of the salivary glands, and refrain from smoking, alcohol consumption, and excessive chewing of hard substances.

Is it necessary to take glutamine?
In general, whether glutamine supplementation is necessary depends on the individual population. Certain groups, such as individuals undergoing intense physical training or patients recovering after surgery, may benefit from supplementation, whereas healthy individuals typically do not require additional intake. When considering glutamine intake, it is preferable to obtain it through a balanced diet. Individuals engaging in high-intensity exercise should maintain a well-structured training and nutrition plan.

Are we not concerned about the window period for HIV testing before surgery?
If a fourth-generation HIV test (simultaneously detecting antigen and antibody) is used before surgery, the window period can be shortened to approximately 4 weeks, which in most cases covers potential infection risks prior to the procedure. For patients without clear high-risk behaviors and no abnormal symptoms before surgery, using this testing method results in a low probability of missing an infection during the window period, effectively ruling out HIV infection, thus making excessive concern about the window period unnecessary.

Is HIV testing also performed during routine hospitalization?
HIV screening is commonly conducted by healthcare facilities when patients are scheduled for surgery, blood transfusion, organ transplantation, or invasive procedures. These procedures carry a risk of blood exposure, and prior testing helps prevent cross-infection and ensures medical safety. Certain departments, such as obstetrics, infectious diseases, and emergency medicine, may include HIV testing as part of their routine protocols.
