CBBLE CDSS (conversational decision support system) transcripts:
[29/06, 12:58] PaJR moderator: Morning OPD: This woman made me understand "cotton wool sensation" today like never before!
15 years back she had a sudden sensation of "lotulo ki diginattu" while walking and the physician who recorded her BP soon after told her it's sky high! I never thought of cotton wool sensation in this manner, which means walking on large bales of cotton which also provides a sinking feeling. Till now I had only imagined it as walking on soft ground
[29/06, 13:03] Metacognitist Mover and Shaker1: Diabetes?
[29/06, 13:05] PaJR CBBLE moderator: Till now not detected
Perhaps less sarcopenia as she regularly exercises her arms in the spinning loom
[29/06, 13:07] Metacognitist Mover and Shaker1: What is the working diagnosis sir?
[29/06, 13:14] PaJR CBBLE moderator:
Posterior circulation TIA
Followed by no recurrence
On stroke prophylaxis
[29/06, 13:18] Metacognitist Mover and Shaker1:
But what can explain the peripheral neuropathy?
[29/06, 13:19] Metacognitist Mover and Shaker1:
Was a bit surprised but one similar patient - very healthy otherwise - 63/F turned out to have MS!
[29/06, 17:11] PaJR CBBLE moderator: It's not peripheral neuropathy!
It's likely to be lemniscal involvement in a posterior circulation TIA
[29/06, 17:16] Metacognitist Mover and Shaker1: Reeks of MS!
Small fiber testing?
[29/06, 17:19] PaJR CBBLE moderator: She has vascular risk factors and it happened just once 15 years back!
More here about lemniscal involvement in posterior
circulation TIAs 👇
[29/06, 17:23] Metacognitist Mover and Shaker1: MRI sir?
[29/06, 17:23] PaJR CBBLE moderator: That reminded me to share this 35 year old woman with Charcots joints referred by orthopedic yesterday where loss of joint position sensation was elicited and reflexes were overall brisk suggestive of a high cord lesion. @PG Med 2022 @Unknown Medical Student @Pushed Comm 1AI23 Can you share the detailed history and examination findings of this lady currently admitted in orthopedics?
[29/06, 17:23] Metacognitist Mover and Shaker1: Recency and recall bias says MS. Forgive me. Where did those vascular factors hide for the last 15 years you'd think?
[29/06, 17:24] PaJR CBBLE moderator: Nothing was done 15 years back for that Tia except stroke prophylaxis which she has been remarkably consuming since then! @Pushed Comm 1AI23
[29/06, 17:24] Metacognitist Mover and Shaker1: MRI now?
[29/06, 17:26] PaJR CBBLE moderator: No focal neurological deficits after that Tia episode
[29/06, 17:26] Metacognitist Mover and Shaker1: Walk in Glencoe mountain trail (Scottish Highlands) and Neurology discussion with @pajr CBBLE. Nirvana.
[29/06, 17:26] Metacognitist Mover and Shaker1: Assuming bedside tests for small fiber neurological deficits were done?
[29/06, 17:29] PaJR CBBLE moderator: Oh you know how our OPD is! She had come for a recent scare where she developed a premonition of another episode @Pushed Comm 1AI23 @ Med Pg 2021 may be able to share what details she could gather from the quick OPD examination
[29/06, 17:29] PaJR CBBLE moderator: Recall the secondary MND we shared here earlier?👇
[29/06, 17:32] PaJR CBBLE moderator: Check out her ncv from Nalgonda here and share your thoughts on what MFS means
[29/06, 17:47] Metacognitist Mover and Shaker1: That is M + S = Motor + Sensory?
[29/06, 17:47] Pushed Comm 1AI23: Complaining of neck pain since 1 day
A/w burning type of pain over scalp
15 yrs ago
H/o TIA , diagnosed with Hypertension
Started antihypertensive medication
3 yrs ago
H/o head ache, generalised weakness
For which she was evaluated and told that there is risk of stroke
So started her on antiplatelets since then
[29/06, 18:05] Metacognitist Mover and Shaker1: Thanks. Any UMN or LMN signs she displayed?
[30/06, 10:49] PG 2020 SR: I didn’t see you examining her sir but based on my brief examination in the ward yesterday morning, I don’t think the patient has a high cervical lesion sir. All DTRs were 2+ with absent ankle reflexes, although Shiva mentioned that sir was able to elicit the reflex.
Prachetan, Shiva and I tried and we weren’t able to elicit the ankle reflex. She has some areas of patchy sensory loss in the L5 distribution, which is neither in a root distribution nor in a single peripheral nerve distribution.
It is Spine involvement vs. a peripheral branch of a nerve involved?
Her joint sense was normal (examined by Prachetan), but Romberg’s test was positive. She has reduced vibration sensations, more on the left leg. She has bilateral extensor plantar responses (more indicative of a myelopathy).
She also underwent an L4-L5 laminectomy six years ago. Her NCS was done approximately 2-3 years postoperatively I guess, as she had some sensory disturbances, which showed reduced CMAP and SNAP in all tested lower limb nerves (femoral, anterior tibial, peroneal) except the saphenous nerve.
I think she has a postoperative syrinx at the level of L5, which is causing this, as well as her Charcot’s joints.
May be we need more detailed examination findings.
@Pushed Communicator 1N22 please share detailed history and examination (including the upper limbs)
[30/06, 11:04] PaJR CBBLE moderator: Excellent inputs 👏👏
Wish we could have shared the videos of our clinical examination findings as was routine once @Unknown Medical Student
Please share the clinical examination points in favour of an L5 localisation
[30/06, 13:05] Pushed Communicator 1N22: 16/7/2019:
36-year-old female presented to Orthopedics department with complaints of low back pain radiating along left lower limb, increased on activity and bending forward ,associated with tingling and burning sensation which impaired her normal daily routine
17/7/2019:
MRI LS spine with whole spine screening was done which showed L4 L5 Lytic lesion with disc sequestration with superior margination with stenosis and bilateral EHL weakness
19/7/2019:
Patient was operated with L3 L4 L5 pedicel screw fixation + L4 laminectomy+ fenestration + discectomy was done.
Patient symptoms resolved post-operatively for next 2 years
2021:
Patient again started developing bilateral tingling
Numbness and burning sensation which was progressively increasing since then , circumferential, more below the level of knee than thighs for which PATIENT was symptomatically managed
But there was no significant improvement in symptoms
2023 :
With no significant improvement in previous symptoms, patient started developing swelling of right lower limb below the knee
For which patient Didn’t take any medication or visited hospital.
Swelling of the right lower limb reduced except in the ankle region, which was further progressive and lead to difficulty in walking as the swelling was touching the ground and leading to pain
Eventually, patient also noticed swelling of left ankle region which was less progressive than right .
4/2024 :
Sensory and motor nerve studies of both lower limbs showed absent CMAP and SNAP in most of the tested nerves except bilateral saphenous
Advised for EMG
Personal history :
Mixed diet
B&B habits are regular
Nulliparous
Her husband left her in 2023 and she is leaving alone since then
No comorbidities
Family History :
No H/O any similar complaints in the family
Patient is on :
T.GABAPENTIN 100mg + NORTRIPTYLINE 10mg OD
T.MVT OD
T.DULOXETINE -METHYL COBALAMIN OD
Will share the examination details mam
[30/06, 13:28] PaJR CBBLE moderator: What was the pathology of the lytic lesion on per operative biopsy?
[30/06, 13:32] PaJR CBBLE moderator: The current examination of EHL weakness suggests a marked assymetry in EHL power
Looking forward to your examination findings.
Dyadic conversations between referring surgeon and PaJR CBBLE moderator:
[09/07, 10:25] PaJR CBBLE moderator: Her current finding post 2019 laminectomy in the same area
[09/07, 10:39] PaJR CBBLE moderator:
Thanks for sharing the report
I only got to see the video from which I took a screenshot
[09/07, 11:16] PaJR CBBLE moderator: As her current problem is ankle pain due to the fractures, limiting her mobility, we may need to manage her fractures with a splint and if necessary correct her talar dislocation if feasible before discharging her?
[18/07, 14:16] PaJR CBBLE moderator: @Meta AI Can you share studies suggesting any association between intervertebral disc surgery and development of loss of joint position sensation that predisposes the same patients to develop fractures and dislocations around those joints often labelled as Charcots joints?
[18/07, 14:16] Meta AI: I've searched for studies related to your question. While I couldn't find exact matches, I found some relevant information:
- A study published in the European Spine Journal (2018) investigated the relationship between lumbar spine surgery (including intervertebral disc surgery) and proprioception (joint position sense). The study suggested that surgery may lead to impaired proprioception, which could increase the risk of joint instability and potentially contribute to the development of Charcot joints [1].
- Another study published in the Journal of Orthopaedic Science (2015) explored the effects of spinal fusion on proprioception and found that fusion surgery can lead to decreased proprioception, which may contribute to the development of adjacent segment disease, including joint instability and potentially Charcot joints [2].
- A review article in the Journal of Neurosurgery: Spine (2017) discussed the pathophysiology of Charcot joints, including the role of proprioception and joint position sense. While not specifically focusing on intervertebral disc surgery, the article highlighted the importance of proprioception in maintaining joint stability and suggested that impaired proprioception may contribute to the development of Charcot joints [3].
Regarding the specific association between intervertebral disc surgery and the development of Charcot joints, I couldn't find direct evidence. However, these studies suggest that spinal surgery, including intervertebral disc surgery, may lead to impaired proprioception, which could increase the risk of joint instability and potentially contribute to the development of Charcot joints.
Please note that more research is needed to establish a direct causal link between intervertebral disc surgery and the development of Charcot joints.
