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 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.

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.

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.

Pulmonary infection by capsule-deficient Cryptococcus neoformans (CDCN) is a very rare form of pneumonia and it is seldom seen in the immunocompetent host. The authors experienced a case of pulmonary cryptococcosis by CDCN in 25-year-old woman who was without any significant underlying disease. The diagnosis was made from the percutaneous lung biopsy and special tissue staining, including Fontana-Masson silver (FMS) staining. Fungal culture confirmed the diagnosis afterward. Her clinical and radiologic features improved under treatment with fluconazol. It's known that CDCN is not so readily confirmed because fungal culture does not always result in growth of the organism and the empirical fungal stain is not helpful for the differentiation between CDCN and the other infections that are caused by the nonencapsulated yeast-like organisms. In this report, we emphasize the diagnostic value of performing FMS staining for differentiating a CDCN infection from the other confusing nonencapsulated yeast-like organisms.

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.

BACKGROUND: Wheezing is an important clue in the diagnosis of asthma. Previously, a Korean National asthma survey used a written questionnaire, containing the question, "Have you ever experienced a breathing sound-like 'sack-sack' or a flute sound (the Korean description for wheezing) during the last 12 months?" The response to this question showed a large discrepancy between the prevalence of wheezing and physician diagnosed asthma. This might have resulted partly from a misunderstanding of the question, due to an inadequate description for wheezing. This study was aimed at finding how well the layman understands the term "wheezing" when described as a breathing sound-like 'sack-sack', a whistle or a flute. SUBJECTS AND METHOD: Sixty subjects, without experience of wheezing(group I), and 45 subjects, with chronic cough alleging wheezing(groupII), were recruited from the Hallym University's Sacred Heart Hospital, in Anyang, Korea. Four different breathing sounds; vesicular, wheezing, tracheobronchial and crackle, were played for the subjects, without any experience with wheezing, and they were asked "which sound is most like that you would imagine when asked about a breathing sound-like 'sack-sack', a whistle or a flute?" This was followed by replaying the true wheezing sound, and then a global assessment was requested for the concordance between the real wheezing sound and the imagined wheezing sound. The wheezing sound was played for those subjects alleging wheezing, and they were asked, "have you really experienced that sound". RESULTS: Only 46.7% of group I answered correctly, with 13.3% choosing the vesicular sound, 16.7% the tracheobronchial sound, 5.0% the crackle and 18.3% failed to answer. The concordance between their imagined wheezing and the real sound was 69.3+/- 22.4%(mean+/-S.D.). 77.8% of groupII recognized the correct sound as the one they had experienced. CONCLUSIONS: Language is not sufficient to the layman for describing natural sounds, such as wheezing.
