The posterior cruciate ligament plays as basic stabilizer of the knee. Therefore the knee becomes unstable when tibial insertion of the posterior cruciate ligament is avulsed. The diagnosis may be delsyed or missed because of surgeon's 1sck of awareness or rare condition. The authors treated seven cases of avulsion fracture of posterior cruciate ligsment at the tibial attachment ares ranged from ten to thirty-two years. There were five male and two female. The results were as follows : 1. The cause of all seven cases injury was traffic accident. 2. The physical findings were seven positive posterior drawer test, seven cases of abrasion or laceration over the anterior proximal tibial surface and antero-medial surfsce of the knee joint. 3. The associated injury was comminuted fracture of the tibia and femur (1 case), rupture of collateral ligsment and comminuted fracture of the tibia (1 case) and zygomatic fracture (1 case). 4. The treatment methods were four cancellous fixation, one K-wire fixation after epiphyseal plate fusion but each one pull out wire and dexon suture before epiphyseal plate fusion. 5. The motion of knee joint was within normal limit and no instsbility was inspected at the three months after reduction.

This study was performed to evaluate histopathologic and physical characteristics of anterior capsule during capsulorhexis with a new high-frequency diathermy.The authors investigated the histopathologic characteristics of anterior capsule according to coagulation time and anterior capsular diameter in diathermy capsulorhesxis(DC),comparing with those in continuous curvilinear capsulorhexis(CCC). Thermally induced histopathologic alter-ation was localized at anterior capsule with coagulation for 0.5 second, while it was extended into cortex with coagulation for 2 seconds.When capsulorhexis was performed with diameter of 6 mmand the margin was pulled with iris retractor,anterior capsular edge was fully extended both in CCC and DC.But with diameter of 3.5 mm,DC mostly led to tear of capsular edge on its extension,while CCC permitted full extension of anterior capsular edge.These results suggest that strength of anterior capsular edge in DC is inferior to that in CCC.However diathermy capsulorhexis is a useful alternative technique in cases,which CCC is difficult to perform,such ashypermature or congenital cataracts.

Eosinophilia is a common finding in premature babies during the neonatal period. Serial eosinophil counts were determined in 94 hospitalized, appropriately grown premature in fants whose gestational ages ranged form 28 to 36 weeks. The incidence, severity and etiologic factors of eosinophilia were retrospectively studied in premature infants, who were divided into three groups according to their gestational age. The results were as follows: 1) Absolute eosinophilia (>700/mm3)was documented in 46.8%(44/94). 2) The duration of TRN and antibiotics was cignificantly higher in infants with eosinophilia than withour eosinophilia (p<0.05). The gestational age of the infants with eosinophilia was significantly shorter than that of the infants without eosinophilia (p<0.05). The infants with eosinophilia started with bottle feeding significantly earlier than the infants without eosinophilia (p<0.05). 3) The infants younger than 30 weeks of gestational age have greater incidence of eosinophilia (75%) than the infant with the gestational age between 34 and 36 weeks (34.3%)(p<0.05). 4) The incidence of mild eosinophilia was higher in the group with gewtational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05).Also, the incidence of severe eosinophilia was significantly higher in the group with gestational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05). 5) Eosinophilia was more prevalent in the infants who received parenteral nutrition composed of glucose, amino acid and lipid(77.8%) than the infants who received only glucose(34.1%)(p<0.05). 6) Gestational age and birth weight were significantly lower in infants with severe eosinopilia than those of mild or moderate eosinophilia. The duration of TRN and antibiotics were significantly longer in infants with severe eosinophilia than those of mild or moderate eosinophilia (p<0.05). 7) The peak eosinophil count was observed significantly later in severe eosinophilic group (26.5 13.1 days)than in non-eosinophilic group(14.4 9.0 days)(p<0.05). The above results suggest that eosinophilia in premature infants may be the effecto of immature immunologic responses to the intravenous administration of extemal antigens like amino acid, lipid and antibiotics.

Pyogenic arthritis remain a difficult problem, despite the availability of a wide range of powerful modernantibiotics. Early and correct diagnosis is imperative to assure the prompt initiation of an effective therapeuticregimen and the prevent of late sequela. Careful clinical, laboratory and roentgenological analysis arefundamental to early and precise diagnosis. Therefore, plain roentgenogram shold not be overlooked. A radiologicaland clinical observation was made in 51 cases of pyogenic arthritis admittted to Chosun University Hospital duringthe period from January 1976 to Dec. 1983 and following results were obtained. 1. Among the 51 cases, 36 cases(70.6%) were male and 15 cases(29.4%) were females. The most prevalent age was 5 to 9 (27.6%). 2. Symptom durationless than 5 days was in 21 cases (41.2%) and more than 31 days was in 6 cases (11.7%). 3. The most common symptomon admission was pain around the involved joint and others are limitation of motion, swelling, tenderness, fever,local heating and erythema. 4. The underlying causes were composed of unknown in 21 cases(41.2%), trauma in 18cases(35.3%), infections focus in 8 cases (15.7%) and iatrogenic reasone 4 cases(7.8%) 5. The msot commonlyaffected joint was hip joint (45.1%). The other affected sites in order of frequency were knee, ankle, shoulder,S-I and elbow joint. In infants and children, hip and knee joint are commonly affected; In adults, knee joint ismost commonly affected. 6. In laboratory findings, the number of W.B.C and E.S.R were increased in 56.9%. Symptomduration more than 31 days in 5 cases were increased E.S,R only. Causative microorganism was isolated in 31 cases;the most common microorganism was Staphylococcus auterus in 22 cases. Others are B-hemolytic Streptococcus,Enterobacteriaceae species and Pseudomonas aeruginosa. 7. In 26 cases(50.9%) of the patients, roentgenographicfinding was negative. The most common radiological findig was soft tissue swelling and the others are include inorder of frequency: joint space widening, small erosions in articular cortex, subchondral osteoporosis. The comonradiological findings of symptom duration more than 31 days in 6 cases were lost of entire cortex, ankylosis andjoint space narrwoing.

Primary non-Hodgkin's lymphoma of the brain is a rare malignancy and there are known to occur almost exclusively in brain parenchyme. Recent immunological advances and immunohistochemical techniques have provided new insights into the pathogenesis and diagnosis of the malignant lymphoma even in the small biopsied tissue and the majority of these CNS tumors is thought to be derived from B lymphocytes. A 22-year old man was admitted due to headack, dizziness and walking difficulty for 2 months. On the initial CT scan, there were two enhancing lesion in the suprasellar area and pineal gland which were completely disappeared with steroid therapy and three new lesions appeared on the follow-up CT and MRI studies in corpus callosum, third ventricle and left cerebral peduncle. The serial cytologic smears of cerebrospinal fluid and a stereotaxic biopsy tissue from the corpus callosum mass showed diffusely homogenous infiltration of neoplastic large noncleaved lymphocytes with focal perivascular arrangement. On the immunocytochemical stains, the reaction was negative for GFAP, positive for LCA and MB2, and negative for MT1. After radiation therapy, the masses completely disappeared on the follow-up CT scan and the patient was discharged free of all the clinical symptoms.

Deregulation of G1 cyclins has been reported in several human and rodent tumors including colon cancer. To investigate the expression pattern of G1 cyclins in 1,2- dimethyl-hydrazine dihydrochloride (DMH)-induced rat colon carcinogenesis, we studied the expression of cyclin D1 and cyclin E by quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis and immunohistochemistry (IHC). The mRNA level of cyclin D1 was increased 1.2-fold in adenocarcinomas but not significantly in adenomas, when compared with normal rat colonic mucosa (p<0.05). The cyclin E mRNA level was increased 2.7-fold in adenomas and 3.3-fold in adenocarcinomas (p<0.05). The PCNA mRNA level was also increased 1.9-fold in adenomas and 1.8-fold in adenocarcinomas (p<0.05). Immunohistochemical staining revealed exclusive nuclear staining of the neoplastic cells for cyclin D1, cyclin E and PCNA. Cyclin D1 expression was detected in 56.3% of the adenomas and in 61.5% of the adenocarcinomas examined, whereas cyclin E expression was detected in 87.5% of the adenomas and in 92.3% of the adenocarcinomas. Overall, cyclin D1, cyclin E and PCNA expression was significantly increased at both the mRNA and protein levels in normal colonic mucosa, adenomas and adenocarcinomas, but there was no significant difference in the degree of expression of these genes in adenomas and adenocarcinomas. Our results indicate that the overexpression of cyclin D1 and cyclin E may play an important role during the multistage process of rat colon carcinogenesis, at a relatively early stage, and may disturb cell-cycle control in benign adenomas, and thereafter, participate in tumor progression.

Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

The rapid increases in childhood obesity and physical inactivity are linked to the incidence of diabetes among young individuals. However, few studies have evaluated the prevalence of diabetes among this population. Therefore, we used Korea National Health and Nutrition Examination Survey (KNHANES) data to evaluate the prevalence and management of diabetes and pre-diabetes among young Koreans. We evaluated KNHANES data (2005–2014) from 10–29-year-old individuals. Individuals were considered eligible if they had completed the health examination and the health interview survey, and we excluded individuals with missing data regarding fasting glucose or glycated haemoglobin levels. Among the 100,101 potentially eligible individuals who participated in KNHANES (2005–2014), we included 83,577 (37,677 male and 45,900 female) individuals. The overall prevalences of diabetes and pre-diabetes among 10–19-year-old individuals were 0.2% and 11.9%, respectively. Among 20–29-year-old individuals, the prevalences of diabetes and pre-diabetes were 0.9% and 9.6%, respectively. The overall rates of diabetes awareness during the study period were 36.6% for 10–19-year-old individuals and 50.8% for 20–29-year-old individuals. However, the prevalence of diabetes and pre-diabetes had noticeably increased at the 2013–2014 KNHANES: 0.6% and 25.9% among 10–19-year-old individuals, and 0.8% and 19.2% among 20–29-year-old individuals. The prevalence of diabetes and pre-diabetes is rapidly increasing among Korean teenagers and young adults. Pre-emptive interventions to diagnose and treat diabetes and pre-diabetes are needed to improve glycaemic control among this population.

10.Potential Implications of Long Noncoding RNAs in Autoimmune Diseases
Keun HUR ; Sang Hyon KIM ; Ji Min KIM
Immune Network 2019;19(1):e4-
Long noncoding RNAs (lncRNAs) are non-protein coding RNAs of more than 200 nucleotides in length. Despite the term “noncoding”, lncRNAs have been reported to be involved in gene expression. Accumulating evidence suggests that lncRNAs play crucial roles in the regulation of immune system and the development of autoimmunity. lncRNAs are expressed in various immune cells including T lymphocytes, B lymphocytes, macrophages, neutrophils, dendritic cells, and NK cells, and are also involved in the differentiation and activation of these immune cells. Here, we review recent studies on the role of lncRNAs in immune regulation and the differential expression of lncRNAs in various autoimmune diseases.
