A 12-year-old, castrated male Yorkshire terrier dog presented with frequent regurgitations that had begun 45 days earlier and become more progressive. Radiographs revealed an air-trap region behind the cranial esophageal sphincter muscle in the esophagus and esophagographies with barium contrast showed mild esophageal dilation with decreased motility. Esophageal motility increased within 5 min of neostigmine methylsulfate administration and acetylcholine receptor antibodies titer increased to beyond the normal range. Based on these findings, acquired myasthenia gravis with focal form was diagnosed, making this the first such case diagnosed by an acetylcholine receptor antibody test in Korea.

The epidural blood patch is a relatively new technique for treatment of post spinal headache. Injection of autologous blood into the epidural space afforded prompt and permanent relief. "Pathcing" the dura hole with autologous blood is the most direct therapy available. It has always been used within a few days of development of headache. This procedure may be considered for patients who continue to experience in capacitating symptoms following a trial of supportive therapy. In our patient the epidural blood patch was used successfully on four cases after the development of headache.

PURPOSE: To evaluate the effect of periosteal fixation in patients with large-angle paralytic strabismus that was not corrected through conventional strabismus surgery. METHODS: Four eyes of three patients with large-angle paralytic strabismus who underwent periosteal fixation from June 2014 to August 2014 were examined. All patients presented with exotropia > 50 prism diopters (PD). Two of them showed exotropia caused by chronic complete oculomotor nerve palsy; the other two showed exotropia caused by medial rectus muscle injury during endoscopic sinus surgery. RESULTS: The mean preoperative exodeviation using the Krimsky test was 58 ± 29 PD. The postoperative values were 6.5 ± 9.4 PD at 1 week, and 11.25 ± 2.5 PD at 6 months. The mean surgical effect of exodeviation was 43.75 ± 21.36 PD. CONCLUSIONS: Periosteal fixation is an effective surgery for the management of paralytic strabismus that was not corrected through conventional strabismus surgery.

Purpose: To confirm that the phaco chop method using an illuminated chopper (iChopper; Oculight, Seongnam, Korea) can reduce cataract surgery complications, and that even beginners can safely and effectively perform phaco chop. Methods: We retrospectively analyzed the medical records of the first 30 phaco chop cases using illuminated chopper of four cataract surgeons. Four ophthalmologists had a variety of empirical backgrounds, from those who have experienced more than 10,000 cataract surgery, to beginners who have experienced 20 cataract surgery. Results: Of the total 120 eyes, two eyes (1.67%) had posterior capsule rupture. The chopping method was changed from phaco chop to stop and chop in three eyes (2.5%) including one eye with brown cataract with pseudoexofoliation syndrome and two eyes with nuclear opacity grade ≥5. Conclusions The rates of posterior capsule rupture of phaco chop using an illuminated chopper were very low in four surgeons with various experiences and who became proficient shortly in phaco chop.

Purpose: To minimize ultrasound power use and surgical phaco time in illuminated chop cataract surgery. Methods: The charts of patients who underwent senile cataract surgery by a single surgeon were reviewed retrospectively. A conventional intracameral endoilluminator was used in a Stop & Chop group (n = 45), while an illuminated chopper was used in an illuminated chop (I-Chop) group (n = 71). EFX, a unitless value that roughly correlates with ultrasound energy during phacoemulsification, surgical phaco time, and changes in endothelial cell count were compared between the two groups and the ratio of zero phacoemulsification in the I-Chop group was evaluated. Results: EFX of the Stop & Chop and I-Chop groups was 18.08 ± 16.15 and 0.82 ± 3.53, respectively (p = 0.001), while the surgical phaco time was 185.08 ± 41.42 and 162.04 ± 49.65 seconds (p = 0.01). However, the endothelial loss did not differ in the two groups (7.03 ± 7.89 vs. 7.13 ± 9.47%, p = 0.76). In the I-Chop group, 56 (86%) eyes had zero phaco energy and patients with EFX >1 (n = 6) had more severe nuclear sclerosis grading (2.90 ± 0.71 vs. 4.5 ± 1.0; p = 0.001). Conclusions The I-Chop group had lower EFX and shorter surgical phaco time than the Stop & Chop group. Illuminated chop using an illuminated chopper is one way to attain minimal phacoemulsification.

BACKGROUND: The purpose of this study was to evaluate the toxicity and efficacy of high-dose chemotherapy with busulfan, thiotepa and melphalan (BTM) as a myeloablative regimen in allogeneic bone marrow transplantation (allo-BMT) for patients with acute myelogenous leukemia (AML). METHODS: Twenty-seven patients with AML were enrolled; Sixteen patients had standard risk (SR) diseases (first complete remission (CR1) and de novo AML) and eleven patients had high risk (HR) diseases (second, or subsequent remission, secondary AML, relapsed, or refractory AML, CR marrow with persisting extramedullary manifestation (chloroma), or hypoplastic acute leukemia). The conditioning regimen included busulfan 4 mg/kg/day for a total dose of 12 mg/kg; thiotepa 250 mg/m2/day for a total dose of 500 mg/m2; and melphalan 50 mg/m2/day for a total dose of 100 mg/m2. Cyclosporine A and short-course methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. RESULTS: The median time to recovery a granulocyte count of 0.5 x 109/L was 14 days (range 10~25 days) and platelet transfusion independence was 30 days (range 12~49 days). The major regimen-related toxicities were gastrointestinal-related symptoms including oral mucositis, nausea, vomiting, and diarrhea. All patients experienced oral mucositis (> or = grade 1) and the patients with oral mucositis of equal and greater than grade 3 were 44% in SR and 45% in HR. The toxicities associated with lung, skin, heart and brain were minimal. Three (11%) patients had severe or fatal veno-occlusive disease (VOD). There were five treatment-related death (19%) (hepatic VOD with multiorgan failure (n=3), pneumonia and ARDS (n=2)) within the first 100 days after allo-BMT. There was not a significant difference between SR and HR group (p=0.167). The incidence of acute GVHD equal or greater than grade II was less than 10%. The actual survival at 2 year was 70.4%(95% confidence interval (CI), 54.7%~86.1%)(SR; 81.3% (95% CI; 63.4~99.1%) vs HR; 54.6% (95% CI; 28.7~80.4%), p=0.154). After a median follow-up of 630 days, 18 of 27 (67%, 355~1062 days) patients are alive without evidence of disease. Three of the 27 patients relapsed (SR; 0% vs HR; 55.6% (95% CI; 19.6~71.3%), p=0.004). CONCLUSION: The BTM regimen followed by allo-BMT is associated with acceptable toxicity and appears to have significant activity in patients with AML. It should be used with caution in patients with prior hepatopathy or refractory state who have an increased risk of severe VOD. Busulfan, thiotepa, and melphalan is an effective and alternative myeloablative regimen for patients with AML.

Solitary fibrous tumor is an uncommon submesothelial mesenchymal neoplasm that arises primarily from the pleura. Extrapleural solitary fibrous tumors are rare. Solitary Fibrous tumors are often asymptomatic and discovered incidentally but may become symptomatic when vital structures are involved or they grow large. In general, solitary fibrous tumor is diagnosed on the basis of radiologic findings and its histologic features, with immunohistochemistry serving to support the diagnosis. Most solitary fibrous tumors pursue a benign course, and the single most important predictor of clinical outcome is the ability to excise the entire lesion. We experienced a case of intrapulmonary solitary tumor arising from the right lower lobe which was treated with wedge resection. We report this case of the patient.

To evaluate the potential utility of a self-expandable intratracheal nitinol stent with flared ends for the treatment of tracheal collapse in dogs, endotracheal stenting therapy was performed under fluoroscopic guidance in four dogs with severe tracheal collapse. During the 4 to 7 month followup, after stent implantation, clinical signs, including dyspnea and respiratory distress, dramatically improved in all dogs. The radiographs showed that the implanted stents improved the tracheal collapse, and there were no side effects such as collapse, shortening or migration of the stents. In conclusion, the self-expandable intratracheal nitinol stents provided adequate stability to the trachea and were effective for attenuating the clinical signs associated with severe tracheal collapse.

Lemierre syndrome or postanginal septicemia (necrobacillosis) is caused by an acute oropharygeal infection with secondary septic internal jugular vein thrombophlebitis and frequent metastatic infections. 17-aged girl visted emergency room with dyspnea. She had the symptoms of fever, sore throat and myalgia before 3 or 4 days. She had multiple septic emboli in both lung fields and septic thrombophlebitis of right internal jugular vein. Although Fusobacterium necrophorum is the most common pathogen isolated from the patients, The pathogen can not be confirmed. We experienced a case of Lemierre syndrome with septic embolism after fever, sore throat and myalgia. We present the case with the review of literature.
