The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

BACKGROUND: The keratinocyte growth factor(KGF) is a recently identified mitogen for epithelial cells produced by nomal stromal fibroblasts. ln the skin, KGF has been shown to stimulate keratinocyte proliferation and differentiatian. Dendritic epidermal T cells(DETC) are skin-specific members of the epithelial y 8 T-cell family that reside normally in the murine epidermis. The DETCs recognize antigen expressed by damaged or diseased neighboring keratinoctyes and consequently secrete cytokines sueh as IFN- y, lL-2, IL-4, GM-CSF. OBJECTIVE: The purpose of this study was to observe the expression of KGF mRNA in keratinocyte and DETC as well as to investigate the cytokine-mediated intercellular communication between kerati- nocyte and DETC. METHODS: Using a RT-PCR(reverse transcription-polymerase chain reaction), we examined the expression of KGF mRNA in keratinocyte and DETC, and compared the level of KGF mRNA between resting and activated DETC with Con-A (concanavalin A).

To define indications of primary treatment in ureteroscopic stone manipulation with comparing the success rates and complications of A(11.5F rigid ureteroscopy from March 1989 to April 1993) and B(7.5F rigid ureteroscopy from May 1993 to February 1995) groups, 216 ureteroscopies were performed for ureteral stone removal between March 1989 and February 1995 in our urologic department. The overall success rates of ureteroscopic stone manipulation were obtained and compared according to stone locations, sizes and anesthesia or not. The overall success rate was 85.6%(80% in group A and 94.2% in group B respectively). The success rates in each group A and B were 60% and 77.8% in the upper ureter, 100% and 66.7% in the middle ureter, 80.0% and 95.9% in the lower ureter. There were the more success rates and the less complication rates in group B than group A. The success rates of stone removal are increased and the complications are decreased remarkably in group B(especially in the lower ureter stone). The rapid relief of ureteral obstruction and colic is possible immediately after ureteroscopic stone manipulation. So, we conclude that ureteroscopic stone manipulation is primarily indicated in the treatment of lower ureteral stones.

The authors studied the effect of insufflation of oxygen at 5 cmH2O into the nonventilated lung on the arterial oxygenation in the thoracotomy patients(n=14) who showed PaO2 below 100 mmHg or oxygen saturation below 95% during one-lung ventilation. When applying CPAP 5 cmH2O to the collapsed lung, we inflated the collapsed lung with reservoir bag that is one of the equipment of self made CPAP device. Hemodynamic parameter(mean arterial pressure and heart rate), arterial blood gas analysis and calculated shunt fraction was collected 10, 20, 30min after applying CPAP. PaO2 was significantly increased from 76+/-20mmHg to 180+/-66 (mean+/-SD) and shunt fraction was significantly decreased from 43.5+/-5.6% to 31.5+/-4.9% at CPAP 10 min. There was no significant difference in the PaO2 and shunt fraction between CPAP 10, 20 and 30 min. Heart rate was also significantly decreased with CPAP compared to pre-CPAP value. Other parameter(mean arterial pressure, PaCO2) was not changed with CPAP. The authors conclude that CPAP 5 cmH2O to the nonventilated lung is effective to improve oxygenation when hypoxemia occurs during one-lung ventilation.

We report a case of porokeratosis of Mibelli coexistence with linear porokeratosis in a 28-year old male. He had multiple discrete reddish to brownish annular plaques with peripheral keratotic ridges on the left side of the neck and axilla, and such lesions extended in a linear fashion on the left side of the upper arm and posterior aspect of the lower extremity. The cutaneous lesions started on the left neck and axilla about 6 years prior to consultation. Two years after that, new lesions developed on the left side of the upper arm and lower extremity in a linear fashion. There was no family history of similar skin disorders. A histological examination showed cornoid lamellae in the horny layer. Hypogranulosis, dyskeratotic cells and perivascular mononuclear in-filtrations were also seen beneath the cornoid lamella.

PURPOSE: We report a case of bilateral optic neuritis without encephalomyelitis, following measles that has recently spread in our country. METHODS: Nine-year-old male patient diagnosed as measles based on the typical symptoms and serum IgM positivity complained of sudden decrease in visual acuity of both eyes (FC/50 Cm in both eyes). Bilateral afferent pupillary defect were detected and visual evoked potentials show the delayed P100 latency and the decreased amplitude in both eyes. We diagnosed his case as the bilateral optic neuritis and treated with the high dose steroid therapy. RESULTS: At 2 months after visual loss, the afferent pupillary defect disappeared and the visual evoked potentials returned to normal. At 6 month, the visual acuity of the right and left eyes improved to 0.9 and 1.0, respectively. CONCLUSION: Optic neuritis following measles is a rare entity, and it is the first time such a case has been reported in Korea. This is a rare case where optic neuritis occurred without the symptoms or signs of encephalitis. In this study, we diagnosed and treated the first case of optic neuritis following measles in korea, with satisfactory results.

BACKGROUND: The regular use of soaps and synthetic detergents has been associated with skin dryness and aggravation of dermatological conditions. OBJECTIVE: Our purpose was to investigate the irritancy of 10 hand dishwashing liquids on normal skin. METHODS: The skin changes, responding to repeat patch testing with 10 hand dishwashing liquids, were measured by visual scoring. RESULTS: The results are summarized as follows; 1. Of the 16 healthy volunteers 8 had reactions. 5 women and 3 men, but there was no significant difference in irritancy between men and women. 2. The mean irritancy scores of the 10 hand dishwashing liquids ranged from 0.06 to 0.88. 3. A prominent increase in the degree of erythema in the first 24 hour patch test did not persist beyond exposure day 5, but after day 5, augmented responses of the erythema and scales, even fissuring occurred. 4. The pH of the test solutions of the hand dishwashing liquids ranged from 5.0 to 6.0, but there appeared to be no correlation between pH and irritancy in the dishwashing liquids tested. CONCLUSION: Our data suggests that regular exposure to hand dishwashing liquids may cause disturbances of the skin in a substantial proportion of individuals, and workers should use hand dishwashing liquids in lower concentrations than recommended and only for short periods with protective measures.

Voice changes developing after endotracheal intubation during right hemicolectomy with endotracheal intubation have been found to be due to a right recurrent laryngeal nerve palsy in 43-years-old male patient. It was likely that the inflated cuffed tube rode up to the level of the cricoid cartilage during the course of surgery as traction was placed on the endotracheal tube because the condenser humidifier and breathing circuit weighed heavy. Cuff overexpansion, in addition to muscle relaxation and decreased tracheal elasticity were considered as contributing factors of vocal cord palsy. We believe that tube traction and cuff overexpansion were the mechanism of vocal cord palsy in our patient. So we recommend the routine use of tube stand so that weigh of the breathing circuit does not transmit traction to the endotracheal tube. Concurrently, filling the cuff with a sample of the inspired mixture of gases, saline and 4% lidocaine in special cases or regular deflation of the cuff must be considered.

The methods of treatment of spondylolisthesis range from posterior fusion to instrumentation, and circumferential fusion. Combined anterior and posterior fusion with instrumentation had been carried out in one or two stages and satisfactory results were obtained in nighteen cases with follow-up period of one year to four years at department of orthopedic surgery of Ewha Womans University Hospital from 1987 to 1991. The results were as follows: 1. Of 19 patients, 7 patients were male and 12 patients were famale. 2. The isthmic type was 12 cases (63.1%) and the 5th lumbar vertebral involvement is common (12 cases, 63.1%). 3. The operative treatment was as follows: Posterior fusion with instrumentation was 8 cases, and anterior fusion with instrumentation was 11 cases. 4. The combined anterior and posterior fusion with instrumentation had been carried out in one stage operation at 8 cases, and two stage operation was done at 11 cases. 5. The average operation time was 3.0 hrs in one stage operation, 3.1 hrs in two stage operation, and the average amount of blood loss was 22cc/Kg in one stage, 17cc/Kg in two stage. 6. The satisfactory results were obtained in 19 cases, but there was no specific difference between one stage and two stage operation.
