Morgan Prust, M.D.
Resident in PHS Neurology
PGY -5
I arrived in Lusaka, Zambia in
early October 2018. This was my second trip to Zambia in residency, my first
having been last year, when I spent a month working as a general neurology
consultant at the University Teaching Hospital (UTH) in Zambia’s capital city.
That experience helped catalyze my interest in global health, and I felt so
fortunate to be able to go back. I returned this year to help take care of
patients, collect data for a stroke-related research project, and help out with
the early stages of Zambia’s first ever neurology residency, which officially
got underway a week or so before I arrived. As was the case when I was in
Zambia last year, it’s been an incredible experience, marked with the highs and
lows of practicing medicine in a low-resource setting that has an astronomical
burden of neurologic disease.
Zambia is a landlocked country
in southern Africa, sandwiched between Angola, Congo, Tanzania, Malawi,
Mozambique, Zimbabwe, Botswana and Namibia. It is a former British colony which
gained independence in 1964, and has had a peaceful and relatively stable
existence, although its economy is precariously tied to the country’s copper
trade and its fluctuating fortunes. It has a population of about 17 million, and
Zambia, like many of its neighbors, was hit particularly hard by the HIV
epidemic. While HIV treatment and prevention have significantly improved
overall life expectancies over the past 20 years, the rate of adult HIV
infection in Zambia is still about 13%, and is the population’s greatest driver
of mortality. HIV is associated with a broad spectrum of neurologic diseases
that comprises a subspeciality of neurology in itself. TB meningitis and complications
of CNS opportunistic infections are exceedingly common (it is more common for
patients to present with multiple concurrent CNS OIs than a single one). Epilepsy
is very common, owing to the high rate of brain lesions from CNS OIs and other
neuro-infectious diseases, and poor access to specialized care/AEDs for
patients with primary seizure disorders. Beyond the realm of HIV-associated
disorders, stroke is the eighth leading cause of mortality, and speaks to a
high prevalence of untreated hypertension and diabetes.
For Zambia’s 17 million people,
there are four adult neurologists (and now three Zambian neurology residents). They
all practice at UTH in Lusaka (with the exception of a pediatric neurologist
who practices in a smaller city called Ndola in the country’s Copper Belt region).
The launch of the residency program will hopefully allow the specialty to grow
in a country that sorely needs more neurologists. There is also a steady flow
of expat neurologists and neurology residents like me who come to work for a
month or two a time, owing to the presence of the American neurologists who
work and live there full time. I work primarily with neurologists Omar Siddiqi
and Deanna Saylor as my attending mentors. Omar is based at BIDMC, but primary
lives and works in Lusaka and has been supervising visiting neurology residents
for many years. Deanna, who arrived in Lusaka earlier this year to head the new
residency program, is a neuroimmunologist/neuro-ID specialist from Johns Hopkins.
My typical day involves getting
to the hospital around 7:30am. I round on all the neurology patients in the
ICU, which has about 15 beds and seven ventilators. Common reasons for
neurology admissions to the ICU include cerebral hemorrhages requiring extraventricular
drains, status epilepticus requiring sedative doses of AEDs, and
neuro-infectious emergencies. After rounding in the ICU, I pass through all the
inpatient wards and the emergency ward to see any new stroke patients and to
follow up on all known stroke patients for a research project I’m doing on
aspiration pneumonia and stroke (see next post). In the afternoons, I typically
continue seeing patients, either stroke patients or other non-vascular
neurology consults, and staff cases with Deanna and the other neurology
residents.

CT is the predominant imaging
modality, owing to its relative ease of access, and to the fact that the
hospital’s MRI has been down since this past spring (patients with private
funds can go to one of the local private hospital’s for an MRI, though the
image quality is generally poor). it’s very difficult to get any vascular
imaging other than carotid ultrasound, which significantly limits the ability
to diagnose the cause of an acute stroke. We have an electrophysiology lab
here, which has EEG (including a portable EEG workstation that can be wheeled
to patient’s bedsides) and EMG. Lumbar puncture is very often indicated but are
not infrequently refused by patients or their families due to a widespread
misperception that LPs cause death. This stems from the story of a former
politician with an advanced neurologic illness who died coincidentally shortly
after undergoing an LP. When we do get LPs, the results have to be interpreted
with caution, as the accuracy of the laboratory’s CSF assays is inconsistent
(for example, the RBC count will often be quoted as 0 despite a tap with gross
blood).
Here are some images from some of the patient's I've been taking care of:

Overall, it’s been an incredibly
gratifying experience to be here once again. I feel so grateful for the
opportunity to use the skills I’ve learned in residency in a place where the
need is so great. There are days when the volume of tragedy weighs heavily, but
the joys of working with amazing colleagues and universally lovely and grateful
patients, and getting treat complex and fascinating neurologic illnesses make
it so worthwhile.
