The authors clinically analysed 317 industrial ocular injuries among 16,466 patients who visited department of ophthalmology of Masan Koryo General hospital during the 5 years from January 1, 1982 to December 31, 1986. The results were as follows: 1. The ambulation rate of industrial ocular injuries was 1.9% of all eye patients and 18.4% of all industrial injuries. 2. The incidence was higher in male(95.6%) and in the age of 3 rd decade(5.2%). 3. The incidence of affected side was 54.0% on the right, 37.5% on the left, and 8.5% on both sides. 4. There was no significant differences in seasonal distribution. 5. The most common cause of industrial ocular injuries was iron piece(32.8%) as a flying particle, followed by wire and nail(15.1%) and chemicals(8.2%). 6. Corneal foreign body(15.8%) was the most common disease of all industrial ocular injuries, followed by corneal laceration(12.7%) and thermal burn, conjunctiva and cornea(8.9%). 7. 29.3% of all industrial ocular injuries were hospitalized. Corneal laceration(21.0%) was the most common disease among in-patients and surgical procedures in in-patients included corneal suture(33.0%), lens extraction(17.5%), corneosclecral suture(13.6%). The average duration of hospitalization was 16.8 days. 8. The average duration of treatment required for all industrial ocular injuries was about 46.3 days. 9. The final visual acuity was improved to 0.9 or more in 45.3% and 34 eyes(9.9%) were below 0.1. 10. The most common complication of industrial ocular injuries after treatment was traumatic cataract(18.4%), followed by corneal opacity(16.8%) and irregular astigmatism(14.4%).

Tuberculosis of the thyroid gland is extremely rare with few cases reported in recent years. Tuberculosis may involve the thyroid gland in two main forms. The more common of theses is miliary spread to the thyroid as part of generalized dissemination and less commonly focal or caseous tuberculosis of the thyroid may occur, presenting as a nodule, as a thyroiditis, as a abscess, or as carcinoma like.We experienced two cases of tuberculosis of the thyroid gland presenting with palpable thyroid nodule in 26 year-old female and 65 year-old female patients. They have been clinically and biochemically euthyroid and their thyroid scans demonstrated a cold nodule at right thyroid gland. We found no evidence of tuberculosis elsewhere. The goiter was removed surgically and confirmed to be tuberculosis. They were medicated antituberculous agents after operation and followed up regulary out patient department.We report the cases of two patients with tuberculosis involving thyroid with reviews of literature.

Hallermann-Streiff Syndrome is a rare congenital anomaly characterized by dyscephalia, dental anomalies, hypotrichosis, congenital cataract, bilateral microphthalmia and has characteristic feature of bird face due to marked mandibular hypoplasia and beaked nose. The authors have experienced a case of Hallermann-Streiff Syndrome combined with bilateral aphakia and glaucoma in a 34 years old woman and we report this case with the review of literatures.

BACKGROUND: In recent years, the incidence of extended-spectrum beta-lactamase (ESBL) producing Klebsiella has been steadily increased, and the newer species K. planticola and K terrigena, formerly regarded as nonpathogen, have been reported with astonishing frequency from human infectious processes by some investigators. The aim of this study is to elucidate the isolation rate and antimicrobial susceptibility of recent clinical Klebsiella isolates. METHOD: For the clinical Klebsiella isolates during the period of June 1999 to May 2000, isolation frequency of Klebsiella species by specimen, departments, age, and sex were analyzed. And antimicrobial susceptibilities were also analyzed. RESULT: Isolation rate of Klebsiella in order of decreasing frequency were K. pneumoniae (74:7%), K. oxytoca (12.1%), K. ozaenae(1.7%), K. planticola(1.0%), K. terngena(0.9%), and K, ornithinolytica (0.7%), respectively. K. rhinoscleromatis was not isolated. Compared with outpatients, increase of resistance rates of inpatients's Klebsiella isolates were 10% in ciprofloxacin, 15% in cefoperazone/sulbactam, and the others were ranged from 24% to 31%. Isolation rate of ESBL producing K. pneumoniae by double disk (DD) synergy test was 41%, and detection rates by antimicrobial agents were as follows: cefotaxime (95%), aztreonam (58%), and ceftriaxone (37%). Antimicrobial susceptibility rate with the exception of ampicillin and imipenem decreased from the range of 81%-96% on admission day to 29-62% after one week on admission. CONCLUSION: The isolation rates of K. planticola and K. terrigena were less than 1%. The proportion of ESBL producing K. pneumoniae was 41 %. And the vast majority of multidrug resistant Klebsiella including ESBL producing strains are acquired by hospitalization.

Acute posterior multifocal placoid pigment epitheliopathy(APMPPE) was first described by Gass in 1968. This syndrome is characterized by sudden loss of central vision secondary to multifocal yellowish-white placoid lesion of posterior pole at the level of the pigment epithelium and significant visual improvement after spontaneous resolution within a few weeks. In the early arterial and arteriovenous phase of fluorescein angiography, choroidal fluorescence is blocked by the placoid lesion but becomes hyperfluorescent in the late venous phase due to staining of the lesion. We experienced and treated a case of acute posterior multifocal placoid pigment epitheliopathy associated with bilateral serous retinal detachment in 29 years old male patient, who had a good visual improvement.

PURPOSE: To describe MR findings and differential points of supratentorial cystic intracranial lesions. MATERIALS AND METHODS: We retrospectively reviewed and analyzed the MR findings of 59 patients with supratentorial cystic intracranial lesions, and classified them as follows: tumor-associated cyst, infectious cyst, ex-vacuo type cyst, and congenital/developmental cyst. RESULTS: Among 59 patients, 47 tumor-associated cysts were seen in 17, 42 infectious cysts in 13, 17 ex-vacuo type cysts in 10, and 19 congenital/developmental cysts in 19. In 44 of 47 tumor-associated cysts, increased or inhomogeneous internal signal intensity was seen on T1-weighted image, 37 of 47 showed thick uneven walls ; 35 of 47 had enhancing solid components and there was variable perifocal edema and mass effect. Infectious cysts were multiple (11 of 13). In cases of brain abscess, increased internal signal intensity on T1-weighted image, low signal intensity of abscess wall on T2-weighted image, thick even enhancing wall, and marked perifocal edema(4 of 4) were seen in all four cases. Cysts in cysticercosis were variable in appearance depending on the stage, but were smaller than other cystic lesions. Ex vacuo type cysts were of uniform CSF signal intensity in all pulse sequences and there was no identifiable wall or enhancement associated with enlarged adjacent ventricle and encephalomalacia(17 of 17). Congenital/developmental cysts showed a single lesion(19 of 19), a signal intensity similar to CSF in all pulse sequences(15 of 19), no identifiable wall(16 of 19), no enhancement(17 of 19), and no perifocal edema(19 of 19). CONCLUSION: MR was used to categorize supratentorial cystic intracranial lesions into four groups on the basis of their number, size, internal homogeneity of signal intensity on T1-weighted image, enhancing pattern, perifocal edema and mass effect, thereby improving diagnostic specificity and patient management.
