Small lesions: strongest predictor of cure (OR 10.09)
Large lesions: higher amputation risk and treatment failure
Bone involvement
Significantly worsens prognosis
Increases amputation risk
Treatment adherence
Regular follow-up: second strongest predictor of cure (OR 6.81)
Long duration (months to years) challenges adherence
Prevention considerations
Primary prevention
Protective footwear during outdoor agricultural work
Protective clothing to avoid skin trauma
Community education in endemic regions
Secondary prevention
Early presentation and diagnosis for smaller lesion size at treatment
Community awareness programs: 96% of surveyed endemic villagers had poor knowledge
Psychosocial support to maintain treatment adherence
Patient Discharge Instructions
copy discharge instructions
Mycetoma home care instructions
Medications as prescribed
Take itraconazole with food every time for best absorption
Take co-trimoxazole as prescribed for full cycle duration
Do not stop medications early even if the lesion looks better
Wound care
Keep draining sinuses clean and covered with dressing
Change dressings as instructed
Save any visible grain discharge in a clean container for doctor review
Activity and footwear
Wear closed protective shoes or boots at all times outdoors
Avoid walking barefoot especially on soil or in fields
Protect the affected limb from further trauma
Warning signs to return to hospital immediately
Fever with chills and feeling very unwell
Rapid increase in swelling, redness, or pain in the lesion
Red streaks spreading from the lesion (cellulitis spreading)
Yellow skin or eyes, dark urine (jaundice from liver side effect)
Decreased hearing or ringing in ears (if taking amikacin)
Decreased urine output (kidney side effect of amikacin)
New lesions appearing elsewhere on the body
Inability to walk or use the affected limb
Follow-up expectations
Regular appointments every 4 to 6 weeks during active treatment
Blood tests for liver and kidney function as scheduled
Hearing test during amikacin treatment intervals
Treatment will last at minimum 12 months and often longer
Imaging (ultrasound or X-ray) to check progress every 3 to 6 months
Prevention and lifestyle
Always wear protective footwear in agricultural or outdoor settings
Report any new skin wounds or swellings early
Good nutrition to support immune system and wound healing
Adequate hydration especially when taking amikacin
