Inflammatory nodular vascular diseases of the legs have been classified as severah distinctive entities based on their minor clinical and pathological variations. They have so many common features which often make the differential diagnosis difficult or impossihIe that reevaluation of these diseases is one of the important problems in the dermatologic field. The author studied the clinical and pathological relationship of those diseases in 86 patients including 70 cases of erythema nodosum, 7 of erythema induratum, 3 of panniculitis, and 6 of nodular vasculitis. The results are as follows; l. Erythema nodosum, erythema induratum and nodular vasculitis are most common. In the spring and patient are most often in their twenties. 2. Common to all, females are more commonly affected than males. 3.Erythema nodosum, erythema induratum and nodular vasculitis reveal no definite difference in their clinical pictures and laboratory findings. 4. Erythema nodosum, erythema induratum and nodular vasculitis are founded to be assoeiated with mostly streptococcal infection and/or tuberculosis; panniculitis is associated mainly with streptococcal infection.5. In histopathological findings, tubercle formation and caseation necrosis are more marked in erythema induratum than in erythema nodosum and nodular vasculitis. 6. The panniculitis is characterized by inflammation of the small sized vessels in. subcutaneous tissues; Nodular vasculitis reveals its main lesion in the large sized. Vessels of lower dermis. In erythema nodosum and erythema induratum, small. And medium-sized vessels are involved in subcutaneous tissue.

Ehlers-Danlos syndrome, a heritable disorder of connective tissue by autosomal dominant mode, is very rare disease in this country. Authors described a typical case in 39 years old woman who had a daughter of 6 years old also affectect by this disorder. The patient had the characteristic hyperelasticity of the skin and hyperextensibility of the jonts especially at metacarpophalangeal joint of the hands. She also revealed hyperterolism and aortic insufficiency on X-ray and E.C.G. examination.

A pregnancy is considered postterm if it is beyond 294 days (42 complete weeks). Several investigators have demonstrated that postterm pregnancy may be accompanied by a rise in perinatal morbidity and/or mortality. Abnormalities such as meconium staining, cringenital anomalies, intrauterine growth retardation, postmaturity syndrome, fetal asphyxia have been reported in some cases of reduced amniotic fluid volume (oligohyramnios) which is commonly observed in postterm pregnancies. Amniotic fluid volume has been shown to decrease significantly as gestational age advances beyond term. Oligohydramnios has particular relevance to postterm pregnancies. Poor perinatal outcomes of oligohydramnios on postterm pregnancy have been reported by several authors. To date, however, the relationship between oligohydramnios in pastterm pregnancy and fetal outcome is debatable. The purpose of this clinical study was to evaluate the relationship between oligohydr- amnios and perinatal outcome in 64 cases of postterm pregnancies. Amniotic fluid index(AFI) values were measured semiweekly in 64 good dated, uncomplicated singleton pregnancies. AFI values were categorized into 2 groups. The group 1; patients whose final AFI value was above 5.0 cm; Group 2, patients whose AFI value fell below 5.0 cm. Adverse fetal outcome was defined by the presence of meconium staining, fetal heart rate decelerations, cesarean delivery for fetal distress, low Apgar score at 1 and 5 minutes, neonatal intensive care unit admission, and perinatal mortality. The fetal outcome was compared group 1 with group 2 and results obtained were as follows: 1. The incidence of oligohydramnios in postterm pregnancy was 54.7 %. The average diminution of amniotic fluid index was from 8.2 1.8 cm to 5.6+2.2 cm/week. 2. The incidence of meconium-staining in amniotic fluid was 40.6 % (Group 1: 20.7 %, Group 2: 57.1 %) and showed statistically significant difference between the two groups(p= 0.003). 3. The incidence of Apgar score less than 7 was 23.4% in 1 minute (Group 1: 13.8 %, Group 2: 31.4 %) and 4.7 % in 5 minutes(Group 1: 3.4%, Group 2: 5.7 %), respectively and showed no statistically significant difference between the two groups (p=0.140, p=1.000). 4. I'he incidence of cesarean delivery due to fetal distress was 12.5 % (Group 1: 6.9%, Group 2: 17.1 %) and showed no statistically significant difference between the two groups (p=0.275). 5. The incidence of admission to NICU was 12.5 % (Group 1: 6.9%, Group 2: 17.1 %) and showed no statistically significant difference between the two groups (p=0.275). Adverse fetal outcome was not uniformly observed in postterm pregnancies with oligohydramnios. Amniotic fluid index in oligohydramnios group as a single independent guide was not enough to predict fetal outcomes in postterm pregnancy without specific pathologic condition of fetus.

BACKGROUND: Although hypoxic pulmonary vasoconstriction (HPC) and hypoxic coronary vasodilatation (HCD) have been recognized by many researchers, the precise mechanism remains unknown. As isolated arteries will constrict or relax in vitro in response to hypoxia, the oxygen sensor/transduction mechanism must reside in the arterial smooth muscle, the endothelium, or both. Unfortunately, much of the current evidence is conflicting, especially concerning to the dependency of HPC and HCD on the endothelium and the role of the K+ channel. Therefore, this experiment was attempted to clarify the dependency of HPC and HCD on the endothelium and the role of the K+ channel on HPC and HCD. METHODS: HPC was investigated in isolated main pulmonary arteries precontracted with norepinephrine (NE). HCD was investigated in isolated left circumflex coronary artery precontracted with prostaglandin F2 alpha. Vascular rings were suspended for isometric tension recording in an organ chamber filled with Krebs-Henseleit solution. Hypoxia was induced by gassing the chamber with 95% N2 +5% CO2, which was maintained for 15 - 25 min. RESULTS: 1)Hypoxia elicited a vasoconstriction in NE-precontracted pulmonary arteries with endothelium, but a vasodilatation in PGF 2 alpha-precontracted coronary arteries with and without endothelium. There was no difference between the amplitude of the HPC and HCD induced by two consecutive hypoxic challenges and the effect of normoxic and hyperoxic control Krebs-Henseleit solution on subsequent response to hypoxia. 2)Inhibition of NO synthesis by the treatment with Nw-nitro-L-arginine reduced HPC in pulmonary arteries, but inhibition of the cyclooxygenase pathway by treatment with indomethacin had no effect on HPC and HCD, respectively. 3)Blockades of the TEA-sensitive K+ channel abolished HPC and HCD. 4)Apamin, a small conductance Ca2+/-activated K+ (KCa) channel blocker, and iberiotoxin, a large conductance KCa channel blocker, had no effect on the HCD. 5)Glibenclamide, an ATP-sensitive K+ (KATP) channel blocker, reduced HCD. 6)Cromakalim, an K(ATP) channel opener, relaxed the coronary artery precontracted with prostaglandin F2 alpha. The degree of relaxation by cromakalim was similar to that by hypoxia and glibenclamide reduced both hypoxia- and cromakalim-induced vasodilations. 7)Verapamil, a Ca2+ entry blocker, caffeine, a Ca2+ emptying drug; and ryanodine, an inhibitor of Ca2+ release from SR, reduced HPC, respectively. CONCLUSION: HPC is dependent on the endothelium and is considered to be induced by inhibition of the mechanisms of NO-dependent vasodilation while HCD is independent of the endothelium and is considered to be induced by activation of the K(ATP) channel.

Authors reviewed 459 cases which had been followed up over 3 months after surgery to evaluate the incidence of consecutive esotropia and its associated factors. For every case, we investigated the age at the surgery, the methods of surgery, stereopsis, cycloplegic refractive power, the deviation difference between far and near fixation, the deviation before surgery and the results at the postoperative 1 day, 1 week, 1 month, 4 months, 6 months, 1 year and 3 years. The incidence of consecutive esotropia tended to decrease as time passed, and occurred in 21 cases[4.6%] at the last follow-up[averaging 13.1 months]. When the deviation difference between at the distance and the near fixation was above 10 delta and the results at the postoperative 1 day was overcorrection above 10 delta, with significantly higher[p<0.05] incidence of consecutive esotropia. Other factors were not statistically significant. In conclusion, the preoperative factor was the far and near deviation difference above 10 delta and the postoperative factor was the first day postoperative overcorrection above 10 delta. It is considered that the nonsurgical treatment can be desirable for the former cases, and overcorrection above 10 delta should be avoided for the latter.

Conservative or surgical methods have been used for the treatment of fracture of mandibular subcondyle, but consensus has not been reached in regard to the proper management of this injury. Several problems related to the surgical procedure have led many surgeons to avoid surgical management of condylar fractures in favor of closed reduction and intermaxillary fixations. However, luxation of the condyle may lead to various long-term complications such as open bite on the contralateral side, dysfunction, deviation in opening and closing movements, as well as bone apposition leading to ankylosis. As a consequence, open reduction is preferable when the condyle is displaced. Various methods-for example, direct wiring technique, simple bone plating, dynamic compression plating-have been advocated for the treatment of fracture of mandibular subcondyle. Of such methods, a functionally-stable osteosynthesis can be achieved by compression osteosynthesis methods. Lag screw osteosynthesis is essentially a form of compression osteosynthesis in which the bone fragments are bound to one another as a result of traction from the screw. An advantage of compression osteosynthesis is that the end of a fractured bone can be maintained in an opposed position under pressure, and then primary bone healing occurs by direct osteoblastic activity within the fracture. As well, it obviates or reduces the need for maxillomandibular fixation, as well as the morbidity associated with conventional treatment methods such as facial nerve injury and bone resorption due to wide dissection. We have treated 9 cases of displaced subcondylar fractures of the mandible with the lag screw fixation system which is marketed by the Martin corporation. Mobilization and guidance of the jaw was begun from 7 or 10 days postoperatively. The radiologic and clinical evaluations showed good repositioning of the fragments and good occlusion postoperatively The disadvantage is that surgical procedures are relatively compound, and an additional procedure - removal of lag screw - is necessary after complete bone union. Lag screw osteosynthesis can be added as a another valid armament for plastic surgeons in the management of mandibular subcondyle fractures.

A clinical and histological study of typical sebaceous epithelioma (basal cell epitheioma with sebaceous differentiation) developed secondarily in lesions of nevus sebaceus of Jadassohn is presented. The patient was 42 years old male. The sebaceous epithelioma tends to have about the same clinical characteristics as undifferentiated basal cell epithelioma but it is more often a yellow color. Sebaceous epitheliova may arise from nevus sebaceus and it is preursor of undifferentiated basal ce]1 epithelioma. Histological]y, the preparation showed massive development of sebaceous gland, papillomatous epidermal hyperplasia and maturation of apocrine glands. The tumor cell nests were mostly composed of large sheets of irregularly shaped cells in palisading pattern at the periphery. There were Iarge number of cells with vacuolated cytoplasm resembling sebaceous cell in certain part of the tumor cell masses and several keratin pearls. Diagnosis confirmed by clinical appearance and histological picture. These lesions could be treated sucessfully by wide excision.
