The following are the most important diseases or complications that may be contributed to by parotitis epidemica (mumps):
Eyes and eye appendages (H00-H59).
- Inflammation of the eyes
- Dacryoadenitis (inflammation of the lacrimal glands).
Blood, blood-forming organs – immune system (D50-D90).
- Thrombocytopenic purpura – increased breakdown of platelets (thrombocytes) and consequent increased bleeding tendency.
Endocrine, nutritional and metabolic diseases (E00-E90).
Cardiovascular system (I00-I99)
- Myocarditis (inflammation of the heart muscle).
Liver, gallbladder, and bile ducts-pancreas (pancreas) (K70-K77; K80-K87).
- Pancreatitis (inflammation of the pancreas; about 4%).
Mouth, esophagus (esophagus), stomach, and intestines (K00-K67; K90-K93).
- Sialadenitis (inflammation of the salivary glands).
Musculoskeletal system and connective tissue (M00-M99).
- Arthritis (inflammation of the joints)
Ears – mastoid process (H60-H95)
- Sensorineural hearing loss (due toInvolvement of the auditory nerve; incidence about 4%).
- Deafness (1 case per 20,000 sufferers).
Psyche – nervous system (F00-F99; G00-G99).
- Encephalitis (inflammation of the brain) (1/2,000).
- Meningitis, aseptic (1-10%) (meningitis).
- Myelitis (inflammation of the spinal or bone marrow), aseptic (1-10%).
Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99).
- Epididymitis (inflammation of the epididymis).
- Mastitis (inflammation of the mammary glands)
- Nephritis (inflammation of the kidneys)
- Oophoritis (ovaritis/ovary inflammation; about 5% of girls and adult women with the disease).
- Orchitis (testicular inflammation) (usually unilateral; 20-40% of mostly adult patients) – can lead to male sterility after puberty – especially if bilateral
- Priapism – erection lasting > 4 h without sexual stimulation; 95% of cases ischemic or low-flow priapism (LFP), which is very painful; LFP can lead to irreversible erectile dysfunction after only 4 h; therapy: blood aspiration and possibly intracavernosal (i.c.) sympathomimetic injection; “high-flow” priapism (HFP) requires no immediate measures
