Arteriovenous Fistula of the Filum Terminale Misdiagnosed and Previously Operated as Lower Lumbar Degenerative Disease

Filum terminale arteriovenous fistula (FTAVF) presenting as a cause of failed back surgery syndrome is a rare entity. We report a 48-year-old male patient who presented with clinical features of a conus medullaris/cauda equina lesion. He had upper and lower motor neuron signs in both the lower limbs with autonomic dysfunction. The patient was misdiagnosed and was operated twice earlier for lumbar canal stenosis and disc prolapse. After reviewing his clinical and radiological findings a diagnosis of FTAVF was made. He underwent surgery and there was a significant improvement in his neurological functions. We discuss the case and review the literature on FTAVF's

Hyponatremia in neurological diseases in ICU

Hyponatremia is the commonest electrolyte disturbance encountered in the neurological and neurosurgical intensive care units. It can present with signs and symptoms mimicking a neurological disease and can worsen the existing neurological deficits. Hyponatremia in neurological disorders is usually of the hypo-osmolar type caused either due to the Syndrome of Inappropriate Secretion of Anti Diuretic Hormone (SIADH) or Cerebral Salt Wasting Syndrome (CSWS). It is important to distinguish between these two disorders, as the treatment of the two differ to a large extent. In SIADH, the fluid intake is restricted, whereas in CSWS the treatment involves fluid and salt replacement

Postmenopausal osteoporosis: Our experience

Introduction: There is very little published literature about experience with osteoporosis treatment from our country. Materials and Methods: It is a retrospective analysis of first 50 patients enrolled in our clinic for osteoporosis. Postmenopausal women with T score of less than -2.5 or history suggestive fragility fracture with supportive bone mineral density (BMD) were included. Patients having hypercalcemia, abnormal renal function, myeloma and on long-term steroids were also excluded. Results: Nearly 34% subjects were below the age of 60 years, 47% of subjects were between 60 and 70 years, whereas 18% were above 70 years. Nearly 6% had family history of osteoporosis s or history of osteoporotic fractures. Nearly 20% subjects had fracture prior to starting of any treatment. A total of 86% (40/46) had evidence of Vitamin D (VD) deficiency. Nearly 80% of patients were treated with bisphosphonates, 12% were treated with injectable bisphosphonates, and 8% were treated with teriperatide. Nearly 16% patients had duration of more than 5 years of experience with bisphosphonates. Follow up BMD was available in 25 subjects. BMD had improved significantly in 68% of subjects. In 24% the BMD was stable (the change was less than least significant change (LSC)). In 8% BMD had shown a significant decline while being on treatment. Conclusion: Postmenopausal osteoporosis occurs in relatively younger women in our country. Majority of them are VD deficient. Oral bisphosphonates is the most common used drug; it is fairly well tolerated and effective

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS): A case report and review of literature

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described inflammatory disease of central nervous system with distinct clinical and radiological features. The etiopathogenesis of this rare entity remains to be understood. The histopathological findings closely resemble chronic inflammatory diseases like sarcoidosis and malignancies like lymphoma. With advancements in serology, immunopathology and radiology CLIPPERS is identified as a distinct entity that differs considerably in its clinical presentation, immunopathology, radiological findings and response to steroids. We describe a case that presented to us with progressive quadriparesis and lower cranial nerve deficits whose radiological and pathological findings were consistent with CLIPPERS. The patient had a good outcome with long term immunosuppression
