PURPOSE: To report the visual outcome and to determine the stability of WIOL-CF(R) (GELMED, Praha, Czech Republic) hydrogel full-optics accommodative intraocular lens (IOL). METHODS: The present study evaluated 20 eyes of 10 patients who underwent routine cataract surgery and WIOL-CF(R) accommodative IOL implantation. Measurement included uncorrected/best corrected visual acuities (VA) at near and distant, degree of IOL decentration, degree of IOL tilting and anterior chamber depth on postoperative day 1, 1 month, 2 months, 6 months and 12 months. RESULTS: Result analysis was performed with 19 eyes of 10 patients, except for 1 complicated eye. At 12 months, the uncorrected distance VA of 11 eyes (57.9%) and 17 eyes (89.5%) were 20/25 and 20/40 or better, respectively. At 12 months, the uncorrected near VA of 12 eyes (63.2%) and 18 eyes (94.7%) were 20/25 and 20/40 or better, respectively. There was no statistically significant difference in anterior chamber depth (p > 0.05), IOL decentration (p > 0.05) and IOL tilting (p > 0.05) on postoperative day 1, 1 month, 2 months, 6 months and 12 months. CONCLUSIONS: The clinical results of cataract surgery with WIOL-CF were relatively satisfactory.

PURPOSE: This study was performed to evaluate the recent frequency of karyotypes in different sex chromosome abnormalities and to evaluate the age and clinical manifestations at diagnosis. METHODS: Peripheral blood leukocytes were obtained from subjects who were clinically suspected to have sex chromosome abnormalities and referred to the cytogenetic laboratory in the Department of Pediatrics, Kyungpook National University Hospital from February 1981 to August 2001. RESULTS: The relative frequencies of different sex chromosome abnormalities were Klinefelter (52 percent), Turner (42 percent), XXX syndrome (3 percent) and mixed gonadal dysgenesis (3 percent). The populations of different karyotypes in Klinefelter syndrome were 47, XXY (97 percent) and 46, XY/ 47, XYY (3 percent). The populations of different karyotypes in Turner syndrome were 45, X (67 percent, ), mosaicism (23 percent), and structural aberrations (10 percent). The populations of different karyotypes in XXX syndrome were 47, XXX (67 percent, ) and 46, XX/47, XXX (33 percent). All mixed gonadal dysgenesis were 45, X/46, XY. Eighty one percent of sex chromosome abnormalities was diagnosed after puberty. Patients diagnosed with Klinefelter and Turner syndrome in infancy showed nearly normal phenotypes or had minor congenital malformations. CONCLUSION: Early diagnoses of sex chromosome abnormalities is required to prevent associated morbidities and to maximize growth and development. We have to pay careful attention in diagnoses of Turner syndrome because of the high proportion of mosaicism and structural aberrations.

Most cases of mucosa-associated lymphoid tissue (MALT) lymphoma occur in adults. MALT lymphoma is very rare in children. Helicobacter pylori (H. pylori) infection is known to be an important etiologic factor predisposing to the development of gastric MALT lymphoma. A 12-year-old girl was admitted because of intermittent abdominal pain occurring over the preceding 2 years. Nodular gastritis of the stomach was demonstrated on endoscopy. H. pylori infection was confirmed using the rapid urease test and histopathology. Histopathological examination of gastric biopsy specimens revealed lymphoepithelial lesions pathognomonic of MALT lymphoma, and immunohistochemical staining for CD20 was diffusely positive. Therefore, the patient was diagnosed with gastric MALT lymphoma. Clinical manifestations and histopathologic findings compatible with MALT lymphoma improved with the eradication of H. pylori infection. We report a case of primary gastric MALT lymphoma in a child, associated with H. pylori infection and presenting as nodular gastritis.

Canine coronavirus is a single-stranded RNA virus that causes enteritis in dogs of any age. Coronaviral enteritis is seldom definitively diagnosed, since it is usually much less severe than many other types of enteritis and is self-limiting. Conventional diagnostics for the canine coronaviral enteritis such as polymerase chain reaction (PCR), virus isolation, and electron microscopic examination are inappropriate for small animal clinics due to the complicated experimental processes involved. Therefore, a commercially available lateral flow test kit based on chromatographic immunoassay techniques was tested to evaluate its performance as a first-line diagnostic test kit that could be used in clinics. The coronavirus antigen test kit detected canine coronavirus-infected dogs with 93.1% sensitivity and 97.5% specificity. The detection limit of the test kit was between 1.97 × 10⁴/mL and 9.85 × 10³/mL for samples with a 2-fold serial dilution from 1.25 × 10⁶ TCID₅₀ (TCID₅₀, 50% tissue culture infectious dose). Additionally, the test kit had no cross-reactivity with canine parvovirus, distemper virus, or Escherichia coli. Overall, the commercially available test kit showed good diagnostic performance in a clinical setting, with results similar to those from PCR, confirming their potential for convenient and accurate use in small animal clinics.

Factors such as location, volume, and the type of neoplasm complicate achieving tumor control. Electrochemotherapy (ECT) is a supplementary treatment for inoperable neoplasms in veterinary patients. Three dogs were diagnosed with a tumor. Two were squamous cell carcinoma (SCC), and the other was liposarcoma, each with a single tumor with the size range of 1 to 5 cm. The tumor locations were the cervical, oral, and abdominal cavity. ECT was selected as a treatment. Bleomycin was injected intratumorally at the dose of 0.5 to 1.0 mg/cm3. Five minutes after the injection, electric pulses applied in a sequence of eight pulses lasting 100 µsec each, were delivered in 1,000 V/cm. An evaluation was performed after 1 week, and the next session was administered 2 weeks later. In a patient with oral SCC, the tumor was in partial remission after two sessions of ECT. Another patient with SCC on her neck was showed complete remission after 2 weeks of ECT administration. A third patient showed stable disease for 8 weeks. Complications were mild and transient and included skin necrosis, edema, local pain, and gait disturbance. ECT is a valid adjuvant, especially for inoperable, cutaneous, or accessible intra-abdominal tumors.
