We studied the natural history of asymptomatic early avascular necrosis of the femoral head in forty-three patients(forty-three hips) who had been treated with arthroplasty due to progressed avascular necrosis of femoral head but had no symptoms in the other side. All initial lesions were classified with Ficat staging and International classification(ARCO). The duration until symptom onset and radiologic evidence of disease progression were evaluated. The average follow up period was over 37 months. Among forty-three hips, twenty-nine cases(67.4%) remained asymptomatic until last follow up but fourteen cases(32.6%) were symptomatic during the follow up, and twenty-six cases(60.5%) did not progress on the radiography but seventeen cases(39.5%) progressed to Ficat stage 3 or 4. Fifteen cases of IA, IIA, IB-cental and II B-central without lateral lesion did not occur symptom and didnt progress to Ficat stage 3 or 4 over a period of average 47 months(24-71 months). But fourteen cases of IB, IC, g B and II C progressed to Ficat stage 3 or 4 and they were all lateral lesion. These results suggest careful observation only can be done in the case of small involvement(less than 15%) and medial or central lesion relatively over a long period of time but for the large involvement(more than 30%) and especially lateral lesion, aggressive surgical treatment may be considered even though the early stage of disease for the prevention of progression. However it will need more period of time to accurately compare the results of various methods of treatment.

CT findings and comparison between clinical and CT staging were reviewed in 45 consecutive patients withbiopsy proven carcinoma of the cervix. CT was done for staging of primary untreted cercial cancer in 36 patientsand for diagnosis of recurrent cervical cancer or follow-up study 14 times in 9 patients . The results are asfollows; 1. As comparing with clinical staging in 36 cases, CT agreed with clinical stage in 19 cases (52.8%),upstaged in 10 cases(27.8%) and downstaged inn 7 cases (19.4%). 2. The main upstaged CT findings are detection ofunsuspected bladder or rectal invasion and paraaortic lymph node metastasis. Inadequate delineation ofintravaginal tumor was the leading causes of understage of CT than clinical one. 3. CT detected all 10 cases ofthe hydronephrosis shown by IVP and detected unsuspected bladder invasion in 3 cases. 4. CT was valuable in thediagnosis of recurrent tumor and follow-up study after treatment. 5. CT offeres distinct advantages over clinicalstaging and can be integrated into the present FIGO classification of uterine cervix carcinoma. CT can served asan initial radiological staging work-up of primary of recurrent cervical carcinoma.

Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

Administration of captopril, a scavenger of oxygen derived radicals as well as an inhibitor of angiotensin converting enzyme, has been an efficient way of treating diabetic proteinuria. In the present study, we evaluate whether captopril can ameliorate diabetic proteinuria as an effect on oxidative stress in streptozotocin- induced diabetic rats (STZR). At four weeks after the injection of streptozotocin (50 mg/kg, i.v.), STZR (n = 5) exhibited microalbuminuria. The rate of urinary albumin excretion was 0.5 +/- 0.1 and 2.6 +/- 0.3 mg/24hr in age-matched control rats (CR; n = 5) and STZR, respectively. Compared to CR, STZR also showed an extremely increased rate of urinary lipid peroxides (LPO) excretion, an index of oxygen derived radicals generation. The respective values for CR and STZR were 0.6 +/- 0.3 and 6.9 +/- 0.6 mumol/24 hr. Significant amelioration of urinary albumin and LPO excretion rate by the treatment of insulin (2 U/day) suggests that these are associated with the diabetic state induced by streptozotocin rather than a direct effect of streptozotocin. Chronic administration of captopril, which did not cause any discernible effect on CR, significantly reduced the urinary albumin excretion rate and decreased LPO excretion in STZR. The urinary albumin excretion rate was significantly correlated with the LPO excretion rate (p = 0.0004). These results suggest that oxidative stress can be responsible for diabetic microalbuminuria, and captopril could diminish the lipid peroxidation and ameliorate the microalbuminuria in diabetic rats.

Microform cleft lip is a mild form of incomplete cleft lip, also known as a minimal occult, abortive, forme fruste cleft lip. However, it has no definition and few methods have been reported for its correction. A microform cleft lip is characterized as the incomplete union of the superficial portion of the orbicularis oris muscle. It is more prominent during facial expression than in a resting state. We confined microform cleft lip in our study to the absence of philtral skin change and a contracted position on the top of cupid's bow. During the past 5 years, 17 patients of microform cleft lip were operated on. We corrected the defect of the upper vermilion border and nostril sill with minimal incision, and repaired the underlying lip musculature in superficial discontinuity. Reduction of the widened alar base was performed. Deformed alar cartilage was dissected via rim incision, and suspended in a medial and upper direction with pull-out sutures. The most important thing is precise repair of the superficial portion of the separated orbicularis oris muscle via minimal incision, and it is best to operate after 1-year of age for accurate repair. The results were satisfactory and the parents were also satisfied. The advantages of this procedure are as follows: 1. Less visible, minimal scar on upper lip 2. Simultaneous correction of vermillion notching, deformed cupid's bow and nasal deformity. 3. Eversion of philtral ridge due to tenting effect of horizontal mattress suture 4. Philtral elongation effect by reduction of alar base and Z-plasty of cupid's bow.
