PURPOSE: The aim of this study was to investigate treatment results, toxicity and efficacy of hyperfractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. MATERIALS AND METHODS: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hyperfractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 5 1 years. Initial FlGO stage was 1 stage IB1, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recur rent disease with superior margin at T 12, and inferior margin was between L5 and S 1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m to 30 mg/m (median, 25 mg/m'), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. RESULTS: Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75% and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30% and 3 7 months, respectively. At 1 month after treatment, 4 (40%) achieved a complete response and 6 (63%) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence in 2 patients after paraaortic node irradialion. There was 2 patients with grade 3 to 4 leukopenia and 8 patients with grade 1 to 2 nausea/ vom ting which was usually tolerable with antiemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. CONCLUSION: Hyperfractionated radiation therapy combined with paclitaxel as a radiosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer. Therefore, present results suggest that hyperfractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.

The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.

Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.

4.Upper Eyelid Reconstruction Using the Medpor(R) Sheet and Median Forehead Flap.
Journal of the Korean Ophthalmological Society 2009;50(7):1105-1110
PURPOSE: To report the upper eyelid reconstruction with median forehead flap and Medpor(R) sheet implant following full-thickness eyelid defect resulting from tumor resection. CASE SUMMARY: A 65-year-old woman was examined at our hospital for a recurrent mass on the right upper eyelid. A wide tumor excision with a 3 mm margin and an eyelid reconstruction procedure were performed after a frozen section biopsy revealed a malignancy. The full-thickness eyelid defect was reconstructed with a median forehead flap as a substitute for skin and muscle and a Medpor(R) sheet substituted for tarsal plate was sutured with a lower conjunctiva flap for posterior lamella. The histopathology diagnosis of the lesion showed a well-differentiated squamous cell carcinoma. The lower conjunctiva was separated at 2 weeks after surgery, and then the median forehead flap detached from the upper eyelid skin at 8 weeks after surgery. One year postoperatively, there was no evidence of a wound infection and an exposure of the Medpor(R) sheet. The eyelid had a good cosmetic contour and the movement of the eyelid during blinking was natural. CONCLUSIONS: The use of a Medpor(R) sheet as a substitute for a tarsal plate in reconstructive procedures of the upper eyelid defect shows cosmetic and functional success.

5.Tectonic Deep Anterior Lamellar Keratoplasty in Impending Corneal Perforation Using Cryopreserved Cornea.
Korean Journal of Ophthalmology 2011;25(2):132-135
We report a case of tectonic corneal transplantation for impending corneal perforation to preserve anatomic integrity using cryopreserved donor tissue. An 82-year-old woman exhibiting impending corneal perforation suffered from moderate ocular pain in the left eye for one week. After abnormal tissues around the impending perforation area were carefully peeled away using a Crescent blade and Vannas scissors, the patient received tectonic deep anterior lamellar keratoplasty using a cryopreserved cornea stored in Optisol GS(R) solution at -70degrees C for four weeks. At six months after surgery, the cornea remained transparent and restored the normal corneal thickness. There were no complications such as corneal haze or scars, graft rejection, recurrent corneal ulcer, and postoperative rise of intraocular pressure. Cryopreserved donor lamellar tissue is an effective substitute in emergency tectonic lamellar keratoplasty, such as impending corneal perforation and severe necrotic corneal keratitis.

Objectives:
This study used data from the seventh National Health and Nutrition Survey, a dataset which signifies that dental services in the country exhibit relatively low health insurance coverage and high copay rates compared to other medical healthcare services. We surveyed the utilization rate of dental care and the prevalence of untreated conditions among Korean elders aged over 65.Furthermore, we aimed to present policy implications to improve dental care accessibility and expand health insurance coverage for elders, especially vulnerable individuals who are bedridden or living alone.
Methods:
We used raw data from the seventh National Health and Nutrition Survey to investigate Korean elders’ dental service utilization and untreated conditions. We opted for elders aged over 65 and finalized 1,712 subjects for the analysis. Statistical analysis was performed using IBM SPSS 25.0 (IBM Corp., Chicago, IL, USA). Groups were detailed in terms of strata of variation estimation and elders aged over 65, cluster of district enumeration, and weighted oral survey. We generated a scheme file and employed complex sampling analysis with a statistical significance level of P<0.05.
Results:
This study intended to survey the rate of dental care use and untreated care of Korean elders over 65 using the seventh National Health and Nutrition Survey data which represents our country. 1. Dental care use rate based on general traits showed statistically significant relevance (P<0.01) with lower age, higher income, higher education level, residence of ‘Dong’, and ‘with’ private insurance. 2. In untreated rate of dental care by general traits showed the significant total of 26.1% with female, lower income, lower education level, ‘recipient’ of basic living, and subjectively poor status of oral health. 3. The multiple answers of the patients who went to the dentists over the past year showed dental care details of dental checkups 54.3%, prosthetic dentistry 32.1%, preventive treatment 30.9%, cavity of root canal treatment 25.7%, gum treatment 17.1%, and tooth extraction 14.7%. 4. The reasons for untreated dental care of those untreated subjects showed the highest 34.0% of economic reason, mild condition 32.3%, lack of time 8.2%, and scared of treatment 8.0% in order. Based on this analysis, we intended to suggest policy implications for the necessity of dental checkup expansion and the activation of prevention treatment.
Conclusions
To improve dental care accessibility for elders aged 65 and above, especially the vulnerable individuals who are bedridden or living alone, it is imperative to expand outpatient insurance coverage and tailor the dental services as per their specific needs. Shifting the focus from treatment-oriented health insurance to preventive measures and examination service expansion and invigoration is essential to improve dental health and overall quality of life. It is deduced that expansion of dental care health insurance coverage and checkup services is critical for vulnerable elders, such as those who are bedridden or living alone.
7.Suggestion for Reducing the Platelet Content Requirements of Apheresis Platelet in Korea
Korean Journal of Blood Transfusion 2023;34(3):218-221
In the United States, it was announced that when the platelet count standard for apheresis platelets was changed from 3.0×1011 /unit to 2.5×1011 /unit, the total supply of platelet products would increase by 21∼23%. In Korea, the platelet count standard for leukocyte filtration apheresis platelet products must be at least 2.0×1011 /unit, and 75% of the total test samples must be 3.0×1011 /unit or more. The supply of apheresis platelets will become smoother if this standard is changed to at least 2.0×1011 /unit. This can reduce the frequency of platelet supply crises and help treat patients by reducing the transfusion waiting time for patients who frequently receive platelet transfusions.
