DM arising in patients with cystic fibrosis (CF). It is the most common complication of CF other than those conditions that affect the lungs. It is caused by destruction of islet cells (the cells in the pancreas that make insulin) as well as a decrease in sensitivity of the liver and muscles to the actions of insulin.M results either from failure of the pancreas to produce insulin (type 1 DM) or from insulin resistance, with inadequate insulin secretion to sustain normal metabolism (type 2 DM). Either type of DM may damage blood vessels, nerves, kidneys, the retina, and the developing fetus and the placenta during pregnancy.
The amount of the late fee should vary based on the price of the rental. A $50 charge for a late rental payment is sufficient for a $1000 a month rental. For someone paying $5,000 a month to rent an apartment, a $50 late charge will not seem like much. In this case, something more in the $250 range would be sufficient.
And, by the way, the maximum rate of interest that may be charged under the California Constitution is 10% per year. Contrast this with a 5% late fee imposed for a rent payment that is 10 days late: that works out to over 180% per year! Late fees illegally collected by a landlord should probably be treated as an additional security deposit, returnable at the end of the lease with interest.
