Oral MedicineThe rash in scarlet fever is characterized by small, raised, red bumps that feel like sandpaper when touched. These bumps, known as "Pastia lines," are particularly prominent in skin folds. The rash is caused by the exotoxins produced by Streptococcus pyogenes and typically occurs with a strep throat infection.

General MedicineIn restrictive lung disease, the FEV1/FVC ratio and compliance of the lung are
decreasing.
Restrictive lung diseases, such as pulmonary fibrosis or severe asthma, are
characterized by a decrease in the lung's ability to expand due to factors like
stiffening of the lung tissue or a reduction in the volume of the thoracic
cavity. As a result, the forced expiratory volume in one second (FEV1) is
reduced in relation to the forced vital capacity (FVC), leading to a decreased
FEV1/FVC ratio. Additionally, the compliance of the lung, which is a measure of
the lung's ability to expand and contract, is also decreased in these conditions
because the lung tissue becomes less elastic.
