PURPOSE: To report a rare case of lymphocytic hypophysitis in a 31-year-old woman who presented with gradually progressive bilateral visual loss during the third trimester of pregnancy. METHODS: Ophthalmologic examination revealed best corrected visual acuity of 0.02 OD and counting fingers at 20 cm OS. Pupil examination revealed no relative afferent pupillary defect in either eye and intraocular pressure was normal in both eyes. A visual field test revealed nearly total visual defect sparing superotemporal area OD and total defect OS. An MRI of the head was performed. RESULTS: At the time of transsphenoidal surgery following the patient's delivery, a frozen biopsy of the lesion revealed diffuse lymphocytic infilteration and fibrosis of the pituitary gland consistent with the diagnosis of lymphocytic hypophysitis. Postoperatively the patient was treated for hypopituitarism. At 5 weeks postoperative, her best corrected visual acuity was 1.0 OU, and visual field defects resolved in both eyes. On follow-up by telephone for postoperative 7 months, the patient remained visually asymptomatic. CONCLUSIONS: The clinical presentation of lymphocytic hypophysitis may mimic pituitary adenoma, lymphoma, germinoma, and histiocytosis. The diagnosis should be suspected in any pregnant or postpartum patient with an intrasellar or suprasellar mass.

Purpose: This study was performed to evaluate the incidence of vasovagal reactions (VVRs) and the efficacy of lidocaine injection for prevention. Methods: One hundred seventeen patients diagnosed with hemorrhoids and scheduled to undergo a stapled hemorrhoidopexy (SH) were randomly divided according to submucosal injection to the rectum: lidocaine group (n = 53, lidocaine injected just before full closure of the stapler) and control group (n = 58). Outcomes included baseline patient characteristics (American Society of Anesthesiologists physical status classification, body mass index, diabetes mellitus, hypertension, and previous VVR history), vital signs during the operation, incidence of VVRs (hypotension, bradycardia, dizziness, diaphoresis, and nausea/vomiting), and postoperative complications (pain, bleeding, and urinary retention). Results: Baseline characteristics were similar between groups. The number of patients with lower abdominal pain after firing the stapler and incidence of dizziness were lower for the lidocaine group than for the control group (9.4% vs. 25.9%, P = 0.017; 0% vs. 8.6%, P = 0.035, respectively). However, there were no significant between-group differences in incidence of nausea and diaphoresis (0% vs. 3.4%, P = 0.172) and syncope (1.9% vs. 3.4%, P = 0.612). Fewer patients in the lidocaine group complained of postoperative pain (41.5% vs. 58.6%, P = 0.072), and these patients used analgesics less frequently than those in the control group (28.3% vs. 36.2%, P = 0.374). Conclusion Patients who received a submucosal lidocaine injection prior to SH experienced less lower abdominal pain and dizziness compared with those who received standard treatment. A larger, more detailed prospective study is needed for further analysis.

OBJECTIVE: The authors compare peridural scar formation and adhesion with and without the use of Antiadhesion Barrier Gel(Adba) in an animal model of laminectomy. METHODS: Forty-five Sprague-Dawley rats underwent a two level lumbar laminectomy. The Adba was applied to randomly assigned 30 rats around the dura. Remaining 15 rats underwent same operation without the use of Adba. The rats were sacrificed 2, 4, 8 weeks after surgery by 15 numbers. A gross anatomic assessment of scar formation was done using microdissection by an observer blinded to treatment. Amount of scar formation and tenacity were compared between experimental and control group by a numerical rating system. The histological comparing was also performed. RESULTS: The amount of scar tissue and tenacity were reduced grossly and histologically at postoperative 2, 4, 8 weeks in animal model using Adba. Adba material was absorbed around 4 weeks of postoperative period in model. No special inflammatory reaction was observed, and the healing of wound was not affected by Adba. CONCLUSION: Adba significantly reduces the amount of scar formation and tenacity in rat laminectomy model without impacting the healing of operation wound and other complications.
