Case : A 18 Year old male with Paraparesis
Written by: Shravani Reddy, Roll no:15, 8th semester
I have been given this case
https://hitesh116.blogspot.com/2020/05/elog-13th-may-2020.html?m=1
to solve in an attempt to understand the "patient clinical data analysis" to develop my competency in reading and comprehending clinical data including history ,clinical findings, investigations and come up with a diagnosis and treatment plan.
The problems in order of priority I found are:
- PARAPARESIS : causing difficulty in walking from 1 month (Date of admission:may 12th 2020)
- Bilateral lower limb weakness from 1 month
- PAIN in the lower limbs calf muscles from 1 month
- Difficulty in standing from sitting position
- Difficulty in climbing stairs
- Difficulty in holding chappals
- Wasting and thinning of muscles (LL>UL)
- Fever from 1 week
On examination:(positive findings)
- Pallor is present(HB : 10.4 gm/dl)
- Muscle bulk is reduced in both lower limbs(on inspection and palpation)
- Hypotonia in both lower limbs
- Babinski sign is negative
- Deep tendon reflexes are absent
- Lesions are present in the web spaces indicative of scabies (family history - has scabies as it is a contagious disease)
- History of alcohol intake from 2 years weekly twice.
Investigations :
- Peripheral blood smear shows NORMOCYTIC NORMOCHROMIC ANEMIA
- Serology : HIV, HBsAg ,HBC all came as NEGATIVE
- Chest X ray - NORMAL
- ECG - NORMAL
- Thyroid profile - NORMAL
- Nerve Conduction Study- to know whether defect is in myelin sheath or in axon.In this patient ,it indicated bilateral common peroneal and sural neuropathy.
- Normal CREATININE KINASE LEVEL
From above investigations we can rule out following diseases:
- Vitamin B12 deficiency
- No viral involvement
- Thyroid induced myopathy
- No neuromuscular condition(as creatinine kinase level normal)
From above findings.....
i.e.: HYPOTONIA , WASTING , ABSENT DEEP TENDON REFLEXES suggestive of LOWER MOTOR NEURON (LMN) LESION.
ANATOMICAL LOCATION OF ROOT CAUSE:
It could be in the axons of the peripheral nerves because
- Motor functions are affected
- Difficulty in holding chappals
- Ankle jerk reflex is absent
- Nerve conduction study indicated bilateral common peroneal and sural neuropathy.
PROVISIONAL DIAGNOSIS:
- Paraparesis secondary to peripheral neuropathy( bilateral common peroneal nerve and sural nerve involved).
- Scabies
TREATMENT:
PHARMACOLOGICAL COMPONENT:
- Tab.pcm 650 mg thrice daily for fever
- Tab.B -COMPLEX once daily for peripheral neuropathy
- Permethrin 5% lotion overnight application all over the body except face for scabies
NON PHARMACOLOGICAL COMPONENT:
- Proper diet recommended
- Physical therapy to help with the muscle atrophy
