Kienbock's disease is a rare disease that is suspected to be caused by the circulatory impairment or/and trauma to the lunate. The various modes of etiology, progression and the treatment have been suggested without any definite ones. The authors report 13 cases of the Kienbock's disease and the results are as follows:1. The male(10 of 13 patients) and the dominate hand(10 of 13 hands) were the more prevalent. 2. Eight cases had a definite history of trauma and the 5 of them were injured by the hyperextension of the wrist. 3. Eight cases were stage III B according to the Lichtman's classification. 4. Nine cases(69%) showed ulna minus variant, which was thought to have certain significant relation with the cause of this disease.

A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.

Atrial flutter is and infrequent, but potentially unstable tachyarrythmia that occurs in pediatric ages. Transesophageal atrial pacing was used for treatment of 10 episodes of atrial flutter in 7 patients. At the time of atrial flutter conversion, patients were 6 days to 14 years old. 6 patients had associated with congenital heart disease. The atrial cycle length of atrial flutter ranged from 140 to 280 msec with variable atrioventricular conduction. Transesophageal atrial pacing was performed using a bipolar 4 F transesophageal electrode catheter. Atrial flutter conversion was accomplished with stimulation bursts using about 5 seconds of stimuli, 10 msec in duration at 20 to 27 mA. Pacing cycle length was 45 to 110 msec less than the atrial cycle length of tachycardia in 6 episodes. But in a neonate, underdrive pacing converted atrial flutter to sinus rhythm. Conversion attempts were unsuccessful on 2 occasions. Transesophageal atrial pacing is a safe and effective, minimally invasive technique for treatment of atrial flutter in infants and children.

The authers have recently experienced a case of cysticercosis in the left lateral rectus muscleof 9 years old Korean boy. The cyst, 3 X 3 X 5mm of size, was located within the muscle sheath and removed surgically in its capsule, confirmed as cysticercosis microscopically. We presents here a report of cysticercosis with a brief review of literature.

Maternal stress during pregnancy can profoundly affect offspring health, increasing the risk of psychiatric disorders, metabolic diseases, and gastrointestinal problems. In this study, the effects of high prenatal corticosterone exposure on gene expression in the brain and small intestine of rat offspring were investigated via RNA-sequencing analysis. Pregnant rats were divided into two groups: Corti.Moms were injected with corticosterone daily, while Nor.Moms were given saline injections. Their offspring were labeled as Corti.Pups and Nor.Pups, respectively. The brain tissue analysis of Corti.Pups showed that the expression levels of the genes linked to neurodegenerative conditions increased and enhanced mitochondrial biogenesis, possibly due to higher ATP demands. The genes associated with calcium signaling pathways, neuroactive ligand-receptor interactions, and IgA production were also upregulated in the small intestine of Corti.pups. Conversely, the genes related to protein digestion, absorption, and serotonergic and dopaminergic synaptic activities were downregulated. These findings revealed that gene expression patterns in both the brain and intestinal smooth muscle of offspring prenatally exposed to corticosterone were substantially altered. Thus, this study provided valuable insights into the effects of prenatal stress on neurodevelopment and gut function.
