With the improvements, during recent years, in the control of the infections and nutritional diseases thesubject of congenital malformation becomes of increasing importance. The radiologic signs are crucial for promptdiagnosis of anomalies of alimentary tract and with early identification of resulting complication, surgicaltherapy is usually life-saving. 30 cases of congenital anomalies of alimentary tract in infants were reviewed inrespect of age, sex, incidence and radiological findings. 1. The most common lesion was hypertrophic pyloricstenosis, followed by congenital megacolon and anorectal anomaly, tracheoesophageal fistula, intestinal atresia.2. Male outnumbered female in most congenital anomalies of alimentary tract. 25 cases were under the age of 1month. 3. Common symptoms of upper gastrointestinal tract obstruction are vomiting and abdominal distention. Inthe obstruction of lower gastrointestinal tract, abdominal distention and failure of meconium passage were noted.4. Roentgenologic finding were as follows, a. Chest A-P and lateral view; In tracheoesophageal fistula, sacculardilatation of upper esphagus and displacement of trachea anterolaterally were the most common finding. b. Simpleabdomen: Obstructive pattern of proximal portion of duodenum shows in 11 cases, of distal bowel shows in 16 cases.Duodenal atresia showed “double bubble” sing, hypertrophic pyloric stenosis showed marked gastric distention,paucity of air in small bowel and increased gastric peristalsis were the most common finding. Hirschsprung'sdisease showed absence of rectal gas almostly. The variable length between blind hindgut to anus was seen inanorectal anomalies. c. Esophagogram: Blind sac of upper esophagus was seen at the 4th thoracic spinal level anddisplacement of trachea anteriolaterally. 1 case of tracheoesophageal fistula had an intact esophageal lumen. d.Upper G-I series; In hypertrophic pyloric stenosis, delayed gastric emptying, string or double tract sign were themost common finding and catapiller sign, tit sign, shoulder sing or open umbrella sign were noted. e. Bariumenema; In congenital megacolon, transitional zone and irregular bizzar contraction, “choppywave” were noted.Radiograph made 24 hours after barium enema showed retained barium in the colon. f. Selective retrogradefistulogram, distal loopgram & voiding cystogram: In anorectal anomalies, 3 cases showed rectourethral fistula and2 cases showed rectovaginal fistula and 1 case showed rectovesical fistula. And membranous imperforate anus is in1 case.

The hypotensive effect of diltiazem hydrochloride(Herben(R)) was investigated with 32 cases of essential hypertension. Diltiazem, 90-180mg per day, was administer ed in divided doses to each of the subjects for 6 week and the blood pressure lowering effect was assessed, as remarkably effective when the lowering of blood pressure was, 20mmHg or more of systolic pressure and 10mmHg or more of diastolic pressure; as satisfactorily effective when 20mmH or more of systolic pressure or 10mmHg or more of diastolic pressure was lowered; as fairly effective when 10-19mmHg of systolic pressure and 5-9mmHg of diastolic pressure. 1. With above mentioned criteria, diltiazem was remarkably, satisfactorily and fairly effective in 11(37%), 13(43%) and 1(3%) of 30 patients, respectively, while the drug was ineffective in 5(17%). 2. Diltiazem was effective in lowering of both systolic and diastolic blood pressure, and was effective as a sole agent of as an agent of combination therapy. 3. With diltiazem treatment, the depressed ST segment was conversed to isoelectric line in all of 10 cases which showed ST depression before diltiazem treatment and the elevated ST segment was conversed to isoelectric line in 1 of 2 cases. all of 4 cases with flat T wave and 10 of 12 cases with inverted T wave showed conversion to upright T waves after diltiazem treatment. 4. Undesirable side effects was observed in 2 cases out of 32 cases(6%); 1 case of erythema multiforme-like skin eruption and 1 case of the clinical aggravation of congestive heart failure, in whom the diltiazem administration was discontinued.

PURPOSE: This article is purposed to present the correct statistic method by pointing out the statistical errors after analyzing the method of articles that were published in Korean Academy Journal of Periodontology and made statistic processes in them. METHODS: 488 science papers which being put in Korean Academy Journal of Periodontology published from 2000 to 2006 was divided according to year. RESULTS: In the 308 articles that applied statistic methods, 59 articles (50.0%), the largest portion of all, were included the case that applied incorrect parametric statistic method when needed to apply parametric statistics and 38 articles (32.2%) were included in the case that applied incorrect parametric statistic method when needed to apply non-parametric statistics. CONCLUSIONS: It is necessary to present the cases of inappropriate statistical methods in order to improve the quality of academic researches. Also, to apply adequate methods of statistics, it is suggested to report the articles periodically which are comparing and analyzing the statistical methods that are applied in the international articles in periodontal field.

We have evaluated the onset time and frequency of allergic reactions after topical application of tetracaine cream. Tetracaine cream was prepared on the antecubital area of forearm in 21 voluteers and antiinflammatory cream was applied also on same side forearm under an impermeable occlusive patch dressing. The mean anesthetic onset time of tetracaine site was 24.90+/-7.47 minutes and significant allergic reactions were not found. The ideal percutaneous local anesthetic formulation should have a comparatively low-concetration of drugs and provide a rapid onset of action combined with a deep and relatively prolonged anesthesia of the skin surface, in addition to underlying tissue. Although EMLA cream has been available, it requires a minimum application period of 1 hour using 2.5 g of preparation in combination with an occlusive dressing. The result of this study indicate that 4% tetracaine in carbomer base and in addition with sodium bicarbonate (Imeq/g) provided more rapid onset and prolonged anesthesia without any significant allergic reactions. So, we advise this 4% tetracaine cream for epicutaneous procedures (tattooing, removal of warts or senile ketatitis), venipuncture and venous cannulations, especially in children.

Three cases of hydatidiform mole with a coexisting fetus are described. In two cases, flow cytometric analysis of nuclear DNA content from paraffin-embedded, molar tissues and normal-appearing placental tissues showed diploid pattern. One case had karyotypes of 46, XX both in fetal skin fibroblasts and in molar tissues. Microscopically, the villi showed diffuse hydropic swelling with circumferential trophoblastic proliferations and consistent with the diagnosis of complete mole. Two patient had persistent gestational trophoblastic neoplasia on the follow-up. Therefore, in cases of hydatidiform mole with a coexisting fetus, dizygotic twin pregnancies composed of a normal pregnancy from one ovum and a complete mole pregnancy from the other ovum must be considered and the patients should be followed with serum beta-hCG measurements.

When clinicians faced with an insufficient volume of supporting bone on ideally esthetic and biomechanical position for dental implantation, guided bone regeneration(GBR) was indicated. Although GBR has wide application at clinic, proper time of membrane removal remains qustionable in using non-resorbable membrane, such as non-expanded polytetrafluoroethylene(PTFE). The aim of this study was to compare the effect of maintenance period of PTFE membrane on bone regeneration in rabbit calvarial defects. Eight adult New Zealand white female rabbits were used in this study. Four defects were surgically made in their calvaria. Using a trephine bur, 4 'through and through' defects were created and classified into 3 groups, which were consisted of control group(no graft), experimental group 1(autogenous bone)and experimental group 2(deproteinized bovine bone; OCS-B(R)). The defects were covered with PTFE membrane(Cytoplast(R)). Membranes were removed after 1, 2, 4 and 8 weeks post-GBR procedure in 2 rabbits repectively. All rabbits were sacrificed after 8 week post-GBR procedure. Specimens were harvested and observed histologically. The results were as follow; 1) The use of graft material and membrane was necessary in GBR procedure. 2) When PTFE membranes were removed early, the most favorable bone regeneration was revealed in experimental group I, followed by experimental group II and control group. 3) On GBR, it is recommended that membrane should maintain for 4 weeks with autogenous graft. As well, the use of xenograft need longer maintenance period than autogenous bone. Further evaluations will be needed, such as histomorphologic research, more species and different kinds of graft materials. And on the basis of these studies, clinical researches would be required.

Fistula between the right renal artery and the infereior vena cava is a rare disorder, of which only 7 cases were reported in so far as the authors have reviewed. A 34-year-old man, who had got a stab wound on the abdomen and undergone an abdominal surgery 12 years ago during his military service, visited the hospital because of occipital headache and known hypertension for 5 years. On examination, his blood pressure was 200/140mmhg, and a thrill and loud continuous vascular bruits over the paraumbilical and right loin region were noted. his blood pressure was refractory to usual antihypertensive regimens. The chest X-ray film showed cardiac enlargement and pulmonary congestion. With the aids of abdominal ultrasonogram, static and dynamic renal scanning with (99m)T-DTPA, excretory urogram, aortogram and selective right renal angiogram, he was diagnosed as right renal artery inferior vena cava fistula. After fistulectomy and repair of walls of both vessels, his blood pressure was successfully controlled with drugs.
