ABSTRACT

Epidural fibrosis is a contributing factor to the persistent pain that is associated with failed back surgery syndrome (FBSS) and other pathophysiologies, particularly as it inhibits the passage of regional medications to areas responsible for pain. Therefore, effective mechanical detachment of epidural fibrosis can contribute to pain reduction and improve function in FBSS patients. In this report, we describe the successful treatment of FBSS patients with epidural adhesiolysis using a Fogarty catheter via the transforaminal approach.

ABSTRACT

PURPOSE: To validate intraocular pressure (IOP) measurements using the new Tonopen AVIA® tonometer by comparing values obtained with those measured by manometers placed in the anterior chamber (AC) and the vitreous cavity (VC). MATERIALS AND METHODS: Seventy-nine consecutive patients awaiting phacovitrectomy for epiretinal membrane (ERM) or macular hole (MH) (n=29), vitreous hemorrhage (DMVH) (n=27) or silicone oil removal (n=23) were included in this prospective observational study. A clinician masked to patient information performed a complete ophthalmologic examination, including measurements of corneal thickness (CT), AC depth and axial length. Another examiner simultaneously measured conventional IOP using the Tonopen AVIA® (TIOP) and AC and VC IOPs (ACIOP and VCIOP) using two transducers. RESULTS: The mean TIOP, ACIOP and VCIOP were 16.1 ± 3.8, 16.1 ± 4.4 and 15.5 ± 4.6 mmHg, respectively. There was a good agreement between the TIOP and ACIOP; however, the agreement between TIOP and VCIOP was relatively poor in subgroup analysis. VCIOP was significantly higher than TIOP in the ERM and MH group, with a mean difference of 1.0 mmHg (p=0.042); however, they were significantly lower in the DMVH group, with a mean difference of -0.7 mmHg (p=0.026) and in the silicone oil group (mean difference, -2.3 mmHg) (p<0.0001). In multivariate analysis, TIOP correlated significantly only with CT (p<0.037) and increased by 2.7 mmHg per 100 µm increase in CT. CONCLUSIONS: IOP measurements using the Tonopen AVIA® tonometer showed good agreement with ACIOP values, although TIOP measurements were affected by CT. However, the VCIOP values using the transducer may have over- or underestimated IOP relative to TIOP and ACIOP under various vitreous conditions. Further validation of VCIOP using a cannular type of manometer should be considered.

ABSTRACT

Buerger's disease (thromboangiitis obliterans) is known as a segmental inflammatory vasculitis that involves the small-sized and medium-sized arteries, veins, and nerves. Most effective treatment for Buerger's disease is smoking cessation. Except for the cessation of tobacco use, surgical revascularization is available in severe ischemia and a distal target vessel. Amputation has been used as the last treatment option of the disease up to the present. Increasing limb survival and decreasing amputation rate is important. This case describes the use of spinal cord stimulation (SCS) in patient with Buerger's disease and its effect is not only the complete healing of ulcers but also amputation is not performed.

ABSTRACT

BACKGROUND: The major disadvantage of rocuronium is the withdrawal movement associated with its injection. The analgesic effect of perioperative gabapentin has been evaluated. We investigated the effects of gabapentin on the withdrawal movement induced by rocuronium injection. METHODS: 86 ASA physical status I or II patients, aged 18-69 years who were scheduled to undergo elective surgery with general anesthesia were enrolled. Patients were randomly allocated into two groups to receive either gabapentin 600 mg or placebo 2 hours prior to surgery. The patient's response to rocuronium injection was graded using a 4-point scale. RESULTS: The incidence of withdrawal movement after rocuronium administration was significantly lower in the gabapentin group (55.0% in the control group vs 28.6% in the gabapentin group). The number of patients with generalized response indicating severe pain, was 9 (22.5%) in the control group and 3 (7.1%) in the gabapentin group. CONCLUSIONS: Pretreatment with a single oral dose of gabapentin 600 mg reduced the incidence and severity of withdrawal movement after rocuronium administration.
