“…26) High intracranial pressure pseudotumor cerebri is rare but known in patients with CRF. 7,19,27) In our case, the presence of headache, papilledema, and high CSF pressure was consistent with the syndrome of pseudotumor cerebri. Increased CSF pressure associated with diaphragma sellae defects is considered to be the main pathogenic factor for empty sella, which occurs in 10% of patients with pseudotumor cerebri.…”

A 39-year-old woman was admitted with complaints of headache and nasal discharge on the left for 3 months which was later on proved to be cerebrospinal fluid (CSF). Neurological examination found no abnormalities except bilateral papilledema. Neuroimaging demonstrated enlargement of the lamina cribrosa foramina through which the olfactory nerves pass, as well as empty sella and cerebral cortical atrophy. Bone mineral densitometry showed osteopenia. CSF Ca ＋＋ and blood parathyroid hormone levels were elevated. CSF pressure was 280 mmH 2 O. Bilateral frontal craniotomy was performed to expose the anterior fossa. Foraminal enlargement at the lamina cribrosa was confirmed, and islands of extraosseous calcifications on the arachnoid membrane were identified. The base of the anterior fossa was repaired intradurally with fascial graft and fibrin glue on both sides. No CSF leakage was noted at 1-year follow up. Spontaneous CSF leakage probably resulted from enlargement of the foramina at the lamina cribrosa due to Ca ＋＋ mobilization from bones and pseudotumor cerebri not to the extent of hydrocephalus caused by poor CSF absorption at the arachnoid granulations obliterated by extra-osseous calcareous accumulation.

“…[7][8][9][10] However, the age of the patient in the current case was not consistent with a diagnosis of giant cell arteritis, which typically presents in old age. 11 Moreover, NAION secondary to anaemia or uremic optic neuropathy were excluded following blood investigations while optic nerve drusen, infiltrative optic neuropathies and intracranial space-occupying lesions were ruled out via optical coherence tomography and MRI.…”

“…16 It is important to rule out other possible causes of NAION, such as uremic optic neuropathy, increased intracranial pressure and drug toxicity. [8][9][10] Nanji et al reported an association with optic nerve drusen, which are calcific deposits that form in the optic nerve head secondary to abnormalities in axonal metabolism and degeneration. 7 All of these factors were ruled out in the current patient; however, she had had periodic episodes of hypotension preceding the vision loss.…”

Introduction and objective:While pruritus is a common complication in hemodialysis patients, the pathophysiological mechanisms remain obscure. Recently, B-type (brain) natriuretic peptide (BNP) has been defined as an itch-selective neuropeptide in pruriceptive neurons in mice, and higher serum levels of BNP are frequently observed in hemodialysis patients. The objective of the present study was to evaluate the role of serum BNP in pruritus in patients undergoing hemodialysis. Patients and methods:The current cross-sectional study was performed on 43 patients undergoing maintenance hemodialysis. A visual analog scale (VAS) measuring the general severity of pruritus (values from 0 to 10, with higher values indicating more severe pruritus) in daytime and at night was self-reported by patients. Each patient's background and laboratory tests, including serum BNP in the post-hemodialysis period, were collected. The correlation between VAS and clinical parameters was evaluated. Results: Both daytime and nighttime VAS scores in diabetic patients were significantly less than those in nondiabetic patients. Multiple regression analysis revealed that pruritus in daytime was worsened by serum BNP (β=2.0, t=2.4, P=0.03), calcium (β=4.4, t=5.2, P,0.0001), and β 2 -microglobulin (β=2.0, t=3.0, P=0.007), while it was eased by age (β=-2.2, t=-3.2, P=0.0004). Nocturnal pruritus was severe in nondiabetic patients (β=1.7, t=3.8, P=0.0005) and weakened by the total iron binding capacity (β=-2.9, t=-3.1, P=0.004). Conclusion: It is suggested that a higher level of serum BNP increases the pruritus of hemodialysis patients in daytime and that diabetic patients are less sensitive to itch, especially at nighttime.
