OBJECTIVE: To determine if birth weight greater than 4000gm can be predicted by ultrasound measurement of abdominal circumference(AC) and if shoulder dystocia in macrosomic infants can be predicted by ultrasound measurement of the difference between the abdominal diameter(AD) and biparietal diameter(BPD). METHODS: A Retrospective study was performed of births occuring from March, 1998 to August, 1999 at department of Obstetrics and Gynecology, College of Medicine, Chung-Ang University. Among neonates of birth weight greater than 4000 gm, 50 cases in that ultrasound examination was done within 2 weeks before delivery were selected for macrosomic group and 50 cases were selected for control group during the same period, among neonate of birth weight from 3100gm to 3900gm. RESULTS: 1) Normal spontaneous vaginal delivery(NSVD) was 41 cases in control group and 30 cases in macrosomic group. Among NSVD, shoulder dystocia was 1 case in 41 cases of control group and was 7 cases in 30 cases of macrosomic group. 2) On ultrasound measurement, 6 cases had AC greater than 35 cm in control group and 45 cases in macrosomic group. Among 30 cases in NSVD was done in macrosomic group, difference between AD and BPD was 2.9 0.271 cm when shoulder dystocia was existed and was 2.1 0.409 cm when shoulder dystocia was not existed. Between the two groups, statistically significant difference was detected. 3) When AC(cutoff value of 35cm) was used for screening of macrosomia, sensitivity for macrosomia was 88.2% and specificity was 89.8% and when AD-BPD difference(cutoff value of 2.6cm) was used for prediction of shoulder dystocia, sensitivity for shoulder dystocia was 66.6% and specificity was 95.2%. CONCLUSIONS: In prenatal ultrasound measurement, AC measurement at third trimester of pregnancy will be a valuable indicator for macrosomia screening. The AD-BPD difference of shoulder dystocia group was greater than uncomplicated group in macrosomia and the AD-BPD difference cutoff value of 2.6cm was significant value statistically.

We evaluated 206 eyes of 105 patients who recieved LASIK with Meditec Mel 60 excimer laser and followed up for at least 6 months. We used 6 mm optical ablation zone to every passible patients and excuted photorefractive ablation after making corneal hinge flap using a 160 micrometerplate. The range of refractive error was from -1.75D to -13.50D and patients were divided into 3 group according to their manifest refraction error(spherical equivalent): Group I(<-6.00D, 120 eyes), Group II(-6.25D to -10.00D, 72 eyes), Group III(>-10.25D, 14 eyes). Mean preoperative spherical equivalent was -3.81D in group I, -7.63D in group II and -12.56D in group III. Mean spherical equivalent after LASIK at 1 Month was +0.05+/-0.60D in group I, 0.00+/-0.74D in group II, -0.12+/-0.99D in group III and at 3 Months, -0.11+/-0.58D, -0.19+/-0.75D, -0.59+/-0.90D and at 6 months -0.21+/-0.59D, -0.34+/-0.78D, -1.11+/-0.86D respectively. In group I, 90.6% of eyes were within 1D of attemped correction at 6 Months as were 80.6% in group II and 46.0% in group III. Mean UCVA at 6 month after LASIK was 1.02 in group I, 0.90 in group II, 0.75 in group III and uncorrected visual acuity of 0.8 or better was achieved in 91.6% of 118 eyes in group I, 88.5% of 67 eyes in group IIand 76.9% of 13 eyes in group III. LASIK done experienced surgeon appears to be safe, accurate, efficient to correct myopic refractive error.

Unilateral retinoblastoma has revealed good prognosis after enucleation in long term follow-up period. But unilateral retinoblastoma with delayed diagnosis may result in poor prognosis due to invasion of the optic nerve or choroid or extraocular spread. Medical records of 26 patients(26 eyes) with unilateral retinoblastoma confirmed by biopsy result after enucleation, were reviewed at the Department of Ophthalmology, Yeungnam University College of Medicine from December, 1983 through February, 1998. Age of the patient, ocular findings, diagnostic methods, treatment modality and clinical results were analyzed. Age ranged from 1 to 60 months(average 26 months). Leukocoria was the most prominent ocular sign and retinal detachment or mass was observed by funduscopic examination in most cases. Enucleation was performed in all 26 cases. Chemotherapy and/or radiotherapy were carried out in 19 cases(73.1%). During the postoperative period of 7 months to 15 years(average 5.8 years), any of 26 eyes has not developed the second tumor, but distant metastases were observed in 4 eyes. The regions of distant metastasis were bone marrow, brain, combined bone marrow and brain, and abdomen. Chemotherapy and radiation therapy were performed in those 4 cases, yet 3 of them were died. Twenty-two patients who did not develop distant metastasis are still alive at the final follow-up.

Retained intraorbital foreign body after penetrating orbital injury may affect adjacent tissue and lead to many ophthalmological sequeles such as visual disturbance, EOM limitation, diplopia, strabismus, orbital cellulitis and orbital abscess. If intraorbital foreign body intrudes into adjacent CNS system, it may lead to fatal complications such as meningitis and brain abscess. We should diagnose and treat intraorbital foreign body early and accurately to prevent complications, and rehabilitate damaged tissue anatomically and functionally. A patient with retained intraorbital foreign body after penetrating lower lid injury was transferred to our hospital for lid swelling and periocular pain. We diagnosed and confirmed intraorbital foreign body with use of plain X ray and orbital CT, and removed it with lateral orbitotomy surgical approach.

Ligamentum flavum cysts (LFCs) are rare but clinically significant lesions in the lumbar spine. These cysts, often found incidentally, can mimic the symptoms of intervertebral disc herniation and cause radiculopathy. This article details a case involving an 80-year-old woman with severe lower back and radicular pain due to an LFC at the right L5/S1 facet joint that was unresponsive to conservative treatment. Magnetic resonance imaging and neurography confirmed that the cyst compressed the right S1 nerve root. Surgical excision via partial hemilaminectomy resulted in complete symptom relief and nerve decompression. Histopathological analysis identified the cyst as degenerative without a synovial lining. This case underscores the importance of considering LFCs in the differential diagnosis of neurogenic leg pain and highlights the efficacy of surgical excision for symptom resolution and preventing recurrence.

Ketoprofen, a propionic acid derivative is a non-steroidal anti-inflammatory drug with analgesic activity and it is used in the symptomatic treatment of rheumatoid arthritis and osteoarthritis. When exposed to sunlight, ketoprofen is broken down into various benzophenones. 3-ethyl-benzophenone as the major photoproduct is responsible for the photoallergic reaction to ketoprofen. A 30-year-old male presented with well-demarcated erythematous patches with itching sensation on both his ankle areas. He had applied Ketotop(R) plasters on both his ankle areas for arthralgia, and then the Ketotop(R) plaster-detached areas were exposed to sunlight. Patch test and photopatch test with?as is?showed positive reaction in photopatch test and the ingredients of Ketotop(R) plaster revealed positive reaction to the ketoprofen contained in Ketotop(R) plaster in photopatch test.

Objective: This study aimed to review domestic and international literature on oral health interven-tions for pregnant women and provide basic data for the development of oral health intervention programs. Methods: We used domestic and international search databases, such as Medline, Embase, Re-search Information Sharing Service, Science On, Korea Citation Index, and DBpia. Among papers published between 2003 and 2023, 22 met the selection criteria by combining “pregnant women,” “oral hygiene,” and “oral health.” Results: Since 2007, foreign literature has steadily increased; however, domestic literature has decreased. Overseas research designs were mostly randomized control trials, whereas domestic designs were mostly non-equivalent control group pretest-posttest. The intervention methods in-cluded three preventive programs, five specialized oral care programs, and 14 oral health education programs. Conclusions In-depth research should be conducted to increase the understanding and interest of pregnant women. Systematic intervention programs that consider the effectiveness and sus-tainability of intervention methods should be developed, and policy support should be provided to strengthen the importance of oral health education by experts and institutional improvements.

OBJECTIVES: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease involving the upper and lower motor neuron of the brain and spinal cord, leading ultimately to death due to respiratory failure in most cases. The etiology of ALS is currently unknown, but several studies show that lead exposure might be one of the potential environmental causes of ALS. In this perspective, we introduce a case involving an ALS patient exposed to lead while maintaining mechanical equipment in a waste treatment plant. METHODS: The patient was interviewed and his medical records were investigated to confirm the final diagnosis of ALS. The results of his health examination and working environment measurement were reviewed in order to evaluate the relation of his work with ALS. We also performed an analysis of lead concentration from samples taken from his workplace when we visited the plant to survey the work environment. RESULTS: Based on the patient's clinical information, work environment, relatively high level of blood lead concentration, and several studies proposing the occupational relationship between lead and ALS, his ALS may possibly have been caused by lead exposure at his workplace. CONCLUSIONS: Given the recent situation where the causal association between lead exposure and ALS is still unclear, this case report could be used as a basis to support the relevance of lead exposure with ALS, and to help improve the health and work environment of other workers who are likely to be exposed to lead.
