Enterobacter aerogenes was isolated from CSF and stool cultures

CONGENITAL DERMAL SINUS ASSOCIATED WITH MENINGITIS BY ENTEROBACTER AEROGENES
2/7

#radiology #microbiology #pediatria
Congenital dermal sinus is associated with meningitis caused by atypical pathogens.

Enterobacter aerogenes community-acquired infections associated with congenital dermal sinus are rarely observed.
3/7

#bacteriology #MedTwitter
Most sacral skin dimples are benign.

Some may be associated with spinal dysraphism (e.g., a congenital dermal sinus), which may lead to bacterial meningitis caused by atypical organisms (e.g., Staphylococcus aureus, Escherichia coli, Proteus species, and anaerobes)
4/7
The presence of atypical pathogens, rather than typical pathogens such as Streptococcus pneumoniae or Haemophilus influenzae, suggests the presence of causative complications.
5/7

#Doctor #MedStudentTwitter
Initial antimicrobial therapy was adjusted to cefotaxime (CTX) based on susceptibility testing.

The response to treatment with CTX was partial (the CSF culture remained➕), and a switch to meropenem was required to achieve negative CSF cultures.
6/7

#resident #medicine
In febrile infants, a full physical examination, including back examination, is important.

Physicians should consider meningitis as differential diagnosis for febrile infant patients with dimples and other skin findings.

Skin-biopsy: consistent with a drug rash
Patch testing identified celecoxib as the trigger.

REVERSE ISOTOPIC RESPONSE in a drug rash sparing a healed herpes zoster infection.

#MedTwitter #dermtwitter #Doctor
A reverse isotopic response or an isotopic nonresponse occurs when:
✔️a new skin disorder by an unrelated disease
✔️spares the area of skin previously affected, healed dermatosis.

The mechanism of this phenomenon is unclear.
