There however is no evidence that medications improve outcomes, and symptoms usually resolve without treatment in 1–2 weeks.Avoiding repeated bites can be difficult since it usually requires eradicating bed bugs from a home or workplace; eradication is most effective using non-chemical control methods. Non-chemical control methods include vacuuming carpet and furniture (often with scraping) into a disposable bag which is then sealed into a plastic bag to prevent re-infestation. Other methods include removing textile materials from an area and washing them in hot water (at least 60 degrees Celsius) or freezing them at −20 °C (−4 °F). Most consumer grade freezers are inadequate to kill bedbugs due to not having low enough temperatures. Unremovable textiles such as mattresses can be steamed at least 60 °C (140 °F) and this method can penetrate deep into the textile to effectively kill bed bugs quickly (under 1 minute). Heating tents or chambers can be used for infested materials or entire rooms can be heated to at least 55 °C (131 °F) to effectively eradicate infestation.There is no evidence to indicate that a combination of non-chemical methods plus insecticides is more effective than non-chemical methods alone with regards to eradication of bed bug infestations.Insecticides are mostly ineffective for the eradication of bedbug infestations as most bedbugs are resistant to insecticides, including pyrethroids which are found in approximately 90% of commercial grade insecticides. Furthermore, insect foggers (known as "bug bombs") are ineffective in the eradication of bed bug infestation as they are unable to penetrate bed bug harborages.
Hydropneumothorax is defined as the presence of both air and fluid within the pleural space. An upright chest x-ray will show air fluid levels. The horizontal fluid level is usually well defined and extends across the whole length of one of the hemithorax. Signs and symptoms
This can be remembered by the 4 S:
straight line dullness,
shifting dullness,
splash,
sound of coin. Causes
Iatrogenic: Introduction of air during pleural fluid aspiration in effusion
Presence of a gas-forming organism
Thoracic trauma

Diagnosis
Diagnosis can be via CXR. CT is better to outline borders of air fluid levels, however, CT has a greater radiation exposure. Treatment
Treatment includes ICD (intercostal drainage) of fluid and air and treatment of underlying conditions. References
