“…Younger cases often indicate an environmental source of infection as shown by the unusually young age of initial cases of iatrogenic transmission in the United States and vCJD in the United Kingdom. [17][18][19][20][21][22] Deaths from sporadic prion disease in those aged ,20 years are extremely rare, with only 7 cases of sporadic CreutzfeldtJakob disease previously recorded. 23 In addition to his age, the patient' s multiple concussions were diagnostically deceptive.…”

The occurrence of sporadic prion disease among adolescents is extremely rare. A prion disease was confirmed in an adolescent with disease onset at 13 years of age. Genetic, neuropathologic, and biochemical analyses of the patient’s autopsy brain tissue were consistent with sporadic fatal insomnia, a type of sporadic prion disease. There was no evidence of an environmental source of infection, and this patient represents the youngest documented case of sporadic prion disease. Although rare, a prion disease diagnosis should not be discounted in adolescents exhibiting neurologic signs. Brain tissue testing is necessary for disease confirmation and is particularly beneficial in cases with an unusual clinical presentation.

“…11,12 Moreover, viral transmission, Dellen formation at the limbal area, ocular surface symptoms, and cosmetic appeal are concerns of using patch graft in shunt procedure. [13][14][15] Alternatives to patch graft are either a large scleral flap or scleral tunnel techniques. [16][17][18][19] We proposed a graft-free GDD implantation method that combines advantages of both scleral flap and tunnel techniques while faster, simpler, and with better tube position in the anterior chamber.…”

Abstract:Purpose: To compare the efficacy and safety of graft-free short tunnel small flap (STSF) technique with that of scleral patch graft (SPG) in Ahmed glaucoma valve (AGV) implantation. Design: Randomized clinical trial.Participants: Eighty-eyes of eighty patients with medically uncontrolled glaucoma including 41 in STSF and 39 eyes in SPG. Methods:Patients were enrolled and assigned randomly to STSF or SPG.Main Outcome Measures: tube exposure, Intraocular pressure (IOP), number of glaucoma medications, best corrected visual acuity (BCVA), surgical complications, and success rate ( defined as intraocular pressure (IOP) >5 mmHg, ≤21 mmHg, and IOP reduction ≥20% from baseline at two consecutive visits after three months, no reoperation for glaucoma).Results: only one case in SPG developed tube exposure at 1-year follow-up. The cumulative probability of success during the first year of follow-up was 70% in the STSF and 65% in SPG (P = 0.36). IOP decreased significantly from 29.6 ± 8.6 mmHg at baseline to 16.4 ± 3.6 mmHg at the final follow-up in STSF (p = 0.001). The corresponding numbers for SPG were 30.9 ± 11.2 and 15.8 ± 4.7, respectively (p = 0.001). The final IOP was comparable between both groups (p = 0.65). Mean ± standard deviation of the number of glaucoma medications was 1.8 ± 0.9 in STSF and 1.6 ± 0.9 in SPG at final follow-up (P = 0.32). Postoperative complications developed in 8 patients (19%) in STSF and 9 patients (23%) in SPG (P = 0.81).Conclusions: STSF and SPG techniques had comparable complication rate at one-year followup. Both techniques were comparable in terms of success rate, postoperative IOP, and glaucoma medications.

“…5) Cadaveric dura had been used in dural repair, but the risk of Creutzfeldt-Jakob disease was reported with the use of cadaveric dura in 1980. 15) Nowadays, cadaveric dura is not used, and has been replaced by artificial dura mater. The longterm use of ePTFE sheet as artificial dura mater in vivo still required study to determine its efficacy.…”

Expanded polytetrafluoroethylene (ePTFE) porous material (GORE } PRECLUDE } Dura Substitute) does not degenerate or deteriorate in vivo, and is currently used as artificial dura mater. This material does not adhere well to the surrounding tissues, but cerebrospinal fluid leakage along the suture line has been observed in several cases. We describe a case of craniotomy for tumor resection performed 14 years after dural repair with ePTFE sheet. Histological examination of the ePTFE sheet revealed that the sheet was structurally intact, with no evidence of tissue adhesion or cellular infiltration. However, collagen deposition was observed around the suture thread. When the suture thread was removed the collagen was also removed, and the original needle hole appeared again. No significant changes were observed in the features of the ePTFE sheet even 14 years postoperatively. The formation of fibrous tissue around the needle hole was important in preventing cerebrospinal fluid leakage.
