Tricholroacetic acid (TCA) chemical peeling is an effective, versatle and safe therapeutic method for patients with pigmentary disorders, acne scars and aging skin. With an experienced and skilled operator, the associated complications are rare and tend to be mild. No. ystemic toxicity is known to be induced by TCA. We observed the effect of TCA chemical peeling, evaluated by 242 patients themselves with melasma, freckles, senile lentgines, pigmented nevi, seborrheic keratosis, skin tags or acne scars. The patients evaluated TCA peeling as excellent for the treatment of seboirheic keratosis, pigmented nevi, skin tags and acne scars, and as selectively recommendable for the treatment of melasma, freckles and senile lentigines.

There are numerous drug interactions related to many psychotropic and cardiovascular medications. Firstly, the principles in predicting drug interactions are discussed. Cytochrome P (CYP) 450 plays a significant role in the metabolism of these drugs that are substrates, inhibitors, or inducers of CYP450 enzymes. The two most significant enzymes are CYP2D6 and CYP3A4. The ability of psychotropic drugs to act as inhibitors for the enzymes may lead to altered efficacy or toxicity of co-administered cardiovascular agents as a substrate for the enzymes. The following is also a review of the known interactions between many commonly prescribed cardiovascular agents and psychotropic drugs. Most beta blockers are metabolized by CYP2D6, which may lead to drug toxicity when they use in combination with potent CYP2D6 inhibitors including bupropion, chlorpromazine, haloperidol, selective serotonin reuptake inhibitors, and quinidine. Concomitant administration of lithium with angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and diuretics may increase serum lithium concentrations and toxicity. Calcium channel blockers and cholesterol lowering agents are subject to interactions with potent inhibitors of CYP3A4, such as amiodarone, diltiazem, fluvoxamine, nefazodone, and verapamil. Prescribing antiarrhythmic drugs in conjunction with medications are known to prolong QT interval and/or inhibitors on a relevant CYP450 enzyme is generally not recommended, or needs watchful monitoring. Digoxin and warfarin also have warrant careful monitoring if co-administered with psychotropic drugs.

Ouarian tumors of low malignant potential(OTLMP) or borderline tumors account for approximately 10% of all ovarian neaplasms. Borderline tumors have some but not all of the histologic characteristics af ma lignancy : stratification of epitheliial cells, with some degree of nuclear atypia a,nd inereased mitotic actitity but. without stromal invasion. We reviwed 20 published Rnglish written articlea from 1978 to 1992 and Korean gynecologic cancer regestry of 1990. In this review, we tried to concentrate on several debating is sues in OTLMP: 1) What kind of surgery is needed for each stages?, 2) Is postoperative adjuvant t.herapy needed?, 3) Jf needed, which type? Following result were obtained from the besis of 1516 patients with OTLMP. Patients withh OTLMIP are younger than those with invasive ovarian cancers', mean age was in their forties. The majority of patients(74.5%) had stage I disease, and the incidence dropped ahruptly to 9.4% for stage ll, 15.7% for stage III and 0.4% for stage IV. The most cammon histologic subtype was serous(56.7%), followed by muci noua(38.1%), However, interestingly in Korea and Japan, the mucinous type was the most common one. The primary treatment for OTLMP was surgery, and the conservative surgery to preserve fertility in young women was sufficient for stage I disease with careful follow-up. The majority of patients(79.1%) with stage I disease were treated by surgery alone. Adjuvant such as chemotherapy (CT) and/or radiotherapy(RT) could prolong the recurrence of disease a little later, but failed to increase diaease-free survival significantly in stage I disease. In stageII disease, the surgery should be a total abdominal hysterectomy and bilateral salpingo-oophorectomy with multiple sampling of the peritoneal cavity. About a third of patients with stageII disease received no adjuvant therapy and the others received CT and/or RT, however, there was no difference in outcome of recurrence and survival. In advanced stage. 15% of patients received no adjuvant therapy after initial debulking surgery, and the rest of patients received CT and/or RT. No differences in recurrence and survival between each groups were noticed , too. The status of second-look laparotomy(SLL) did not depend on the stage of the disease. Positive rate of SLL for stage I diaease was not statistically different from that for the combined stages II-IV. Survival for stage I at 5 years was reported to range from 80 to 100%, and even stage III had survival ranging from 64 to 96%. Long-term survival at 15~20 years was also good. Although it is quite difficult to make conclusions because of the lack of prospective randomized studies from this review, it appears clear that surgical removal of the tumor and careful follow-up of patients are all that are necessary in stage I disease and further multi-center prospective study for the effect of adjuvant therapy in advanced disease is definitely needed.

Mucinous tumors of the ovary are the most common tumors arising from the common epithelium of the ovary in Korean. Distinguishing the tumor with borderline malignancy from mucinous cystadenocarcinoma is very important in determining proper therapeutic modalities and prognosis. Authors have undertaken morphometric analysis of various parameters from both borderline lesions and carcinomas of mucinous nature of the ovary. In each, five cases of the borderline and malignant tumors were subjected to be evaluated. Various cytologic and histologic parameters were analyzed using Kontron IBAS-I. 1) The most helpful parameter-for differentiation between borderline and malignant mucinous tumors is cell concentration (sensitivity 80%, specificity 80%). The discrimination value is more than 35 cells per 100 micrometer of the basement membrane length. If the cellular concentration is higher than the discriminating value, that indicates malignancy. 2) Tumor cell height, though it is other parameter of stratification, is not helpful for differentiation of the two lesions. 3) Cytologic atypia, either in size or in form, can not be a criterion distinguishing the borderline from malignancy. 4) Papillary growths can not be a criterion of either borderline and malignant lesions. 5) The degree of irregularity at tumor-stroma interface is not helpful for differentiation between borderline and malignancy.
