Gastric carcinogenesis has been studied in various aspects. Helicobacter pylori (Hp) infection and mutation of the p53 tumor suppressor gene have recently been argued to be important factors of gastric carcinogenesis. There have been many studies to determine the precise mechanism of how Hp is related to gastric cancer, but it is so far still unknown. We studied the relationship of Hp infection and p53 overexpression and tried to discover some significance in clinicopathologic factors such as age, sex, stage, site, differentiation and gross morphology. Ninety-six patients who were diagnosed with gastric cancer at Severance Hospital, Yonsei University Medical College from November 1995 to March 1996, and 96 control patients of non-ulcer dyspepsia (NUD) were studied by endoscopic biopsy of normal gastric tissue and cancer tissue. They also underwent the CLO (Delta West, Melbourne, Western Australia) test for Hp positivity and p53 immunohistochemical stain for p53 positivity. These data were analyzed for comparison with the clinicopathologic characteristics of gastric cancers. In conclusion, the differentiated group cancer had a significantly high Hp positivity and p53 positivity. There is a possibility that Hp infection and p53 tumor suppressor gene mutation might be significantly related in the gastric carcinogenic process of well- and moderately-differentiated adenocarcinomas, but further study is necessary to determine more direct clues on the carcinogenic roles of these factors.

Yonsei Medical Journal.1997;38(2):111-116. doi:10.3349/ymj.1997.38.2.111

Recently, with the widespread use of new imaging techniques, the diagnosis of autosomal dominant polycystic kidney disease (ADPKD) is increasing. To analyze the extrarenal manifestations of ADPKD in Korean patients, we retrospectively studied the clinical characteristics of 30 patients with ADPKD. Thirty Patients with ADPKD who had been diagnosed at Yongdong Severance Hospital from 1988 through 1994 were recruited for this study. All patients' past and family histories were re-evaluated, and charts and radiologic images were reviewed retrospectively. The male to female ratio was 9:21, and the age of initial diagnosis was 39.2 +/- 13.8 (mean +/- SD) years. In 15 cases (50%), ADPKD had been diagnosed by renal symptoms; in 8 cases (26.7%), by chance during evaluation of extrarenal diseases; in 5 cases (16.7%), by family screening; and in 2 cases (6.7%), by uremic symptoms. Extrarenal involvement included hepatic cysts (70%), pancreatic cysts (16.7%), splenic cysts (6.7%), thyroid cysts (6.7%), inguinal hernia (3.3%), and colonic diverticula (3.3%). In 5 cases (16.7%), cardiac valvular abnormalities were noted by echocardiography. Seven patients underwent hemodialysis, and the duration from the initial diagnosis to initiation of dialysis was 9.9 +/- 8.5 (mean +/- SD) years. We investigated the extrarenal manifestations of 30 cases of ADPKD in Koreans, which were also common and clinically important as renal manifestations. Renal cysts are only one of a myriad of renal and extrarenal manifestations of ADPKD. ADPKD should be managed systematically since this disorder is a systemic disease with clinically important involvement of the cardiovascular system, the gastrointestinal tract, the genitourinary system, and the musculoskeletal system.

Yonsei Medical Journal.1997;38(2):101-110. doi:10.3349/ymj.1997.38.2.101

This study was designed to investigate the relationship between nutritional intake and caries experience of junior high school students. The sample consisted of 295 boys and 356 girls in Kangwha county. Dependent variables were total caries experience, occlusal surface caries experience, smooth surface caries experience and DMFS score (Decayed, Missing, Filling Tooth Surface score). Independent variables such as pit and fissure retentiveness of first molars, oral hygiene status, intraoral acidogenicity were also measured by dentists. Other independent variables such as toothbrushing habits, socioeconomic conditions, between-meal eating habits, and daily nutritional intake were determined during an interview. Univariate and multivariate analysis was performed to evaluate how nutritional intake influences caries experience. The results were as follows: 1. The most influential factor on dental caries experience was pit and fissure retentiveness. 2. Dietary fiber and potassium were the significant nutritional factors on total caries experience and occlusal caries experience, and niacin was the significant nutritional factor on smooth surface caries. 3. DMFS score was positively associated with the daily amount of carbohydrate and niacin intake, and negatively associated with total energy intake. The above results suggested that pit and fissure retentiveness was the most influential factor on caries experience. However, in this study, the intake of potassium and niacin was identified to influence the caries experience in addition to confirming the well-known relationship between fiber and carbohydrate intake.

Chang Dong HAN ; Chong Hyuk CHOI ; Chang Ok SUH

Yonsei Medical Journal.1997;38(2):96-100. doi:10.3349/ymj.1997.38.2.96

Nineteen patients received single-dose exposure to 600 rad delivered within 48 hours of total hip arthroplasty (THA) with shielding of the prosthesis region for the prevention of heterotopic ossification. The patients were considered at high risk for developing heterotopic ossification (HO) because of hypertropic osteoarthritis, post-traumatic osteoarthritis or the presence of previously-formed ectopic bone. The average follow-up period was 42 months (range, 37 months-48 months). At a follow-up study, all hips except one were classified as Brooker class 0. The single exception was classified as class I. All patients were asymptomatic at the last follow-up study and no component demonstrated subsidence or radiolucent line indicative of loosening. The authors concluded that 600 rad, single-fraction radiation therapy is cost effective, convenient and safe for the prevention of heterotopic ossification after total hip arthroplasty.

SS-cream is a topical agent for treating premature ejaculation (PE) which is made with extracts from 9 natural products. We evaluated the efficacy of SS-cream in the treatment of PE. An open pilot study was performed in 186 patients with PE. The mean ejaculatory latency from intromission to ejaculation was 1.5 minutes. Sixty-four of the 186 patients (34.4%) were combined with mild erectile dysfunction in whom penile rigidity was not sufficient to be satisfied in sexual activity. Patients were instructed to apply 0.1 gm. of SS-cream on the glans penis 1 hour before sexual contact and to wash out the cream before sexual intromission. Patients were asked to complete a report form including ejaculatory latency, the degree of satisfaction in the sexual lives of both themselves and their partners, and any adverse effects after each application. One hundred and sixty-six out of 186 patients (89.2%) reported they were satisfied with the application of the SS-cream and the mean ejaculatory latency was significantly prolonged to 10.89 +/- 5.60 minutes. The mean ejaculatory latency was 9.85 +/- 3.58 minutes in 52 out of 64 patients (81.2%) with mild erectile dysfunction. There was no significant difference in the changes of ejaculatory latencies between patients with pure PE and patients with mild erectile dysfunction. Twenty patients (10.8%) claimed to have no changes of ejaculatory latencies after the application of SS-cream. Adverse effects were noted in 11 patients (5.9%), which were mild local irritation symptoms in 7 patients, and delayed ejaculation of more than 30 minutes in 4 patients, the symptoms subsided spontaneously within 4 hours. These results indicate SS-cream is effective in the treatment of PE and also PE combined with mild erectile dysfunction with a few side effects. Further studies on the action mechanisms of SS-cream and a double blind placebo-controlled trial are needed.

Yonsei Medical Journal.1997;38(2):86-90. doi:10.3349/ymj.1997.38.2.86

The present study was designed to evaluate the possible beneficial effects of biofeedback-assisted relaxation to pharmacotherapy on blood pressure and heart rate in patients with essential hypertension. Twenty patients with essential hypertension and without any complications or end-organ damage participated in the study. All the patients were using anti-hypertensive drugs. The study protocol consisted of an interview, 10 days baseline, 10 biofeedback-assisted relaxation sessions and a 10-day post-treatment period. Interview blood pressure (BP) and heart rate (HR) measurements, baseline mean values of systolic blood pressure (SBP), diastolic blood pressure (DBP) and HR recorded during the 1st, 10th and 20th minutes of each session and the post-treatment mean values were evaluated. Significant differences were found between the mean values of SBP, DBP and HR after the whole treatment protocol (Wilcoxon signed-ranks test). The mean values of SBP, DBP and HR measurements recorded during the 1st, 10th and 20th minutes of the biofeedback-assisted relaxation sessions, which were evaluated by repeated measures of ANOVA on ranks test, showed a significant decrease only for the 10th minute values at the end of the whole treatment program. Despite a short follow-up, it was suggested that these results were encouraging considering the fact that once the patients are thoroughly instructed in home practice of relaxation and encouraged to develop their own strategies for relaxation, the long term outcome may also be promising.

Yonsei Medical Journal.1997;38(2):79-85. doi:10.3349/ymj.1997.38.2.79

The postmortem stature was measured in 57 Korean adult males (age range: 20-86 years old, mean: 52.3 years old) in supine position. After dissection of the corpses, we measured the maximum length of the remaining limb-bones (humerus, radius, ulna, femur, tibia and fibula). The correlation coefficients between the stature and each limb-bone length were calculated. Simple regression equations for estimating stature from each limb-bone length and multiple regression equations from the combination of limb-bone lengths were also obtained.

Yonsei Medical Journal.1997;38(2):73-78. doi:10.3349/ymj.1997.38.2.73

We studied the clinical characteristics, location of epileptogenic regions, and the surgical outcomes in 18 patients with intractable epilepsy associated with previous CNS infections. All patients underwent an extensive presurgical evaluation and 11 patients had intracranial EEG monitoring. On the basis of presurgical evaluation, epileptic regions were localized to the mesial temporal (n = 12) and the neocortical (n = 6) regions. The age of the time of CNS infection was significantly younger and the latent period of non-febrile seizures after CNS infection was longer in patients with mesial temporal lobe epilepsy (MTLE). MRI showed hippocampal atrophy and hippocampal signal changes in 11 of 12 patients with MTLE. Among 6 patients with neocortical epilepsy (NE) 5 patients had normal MRI and one showed cerebral hemi-atrophy. Surgery was successful (class I & II) in all patients with MTLE, however, in the patients with neocortical epilepsy, seizure-free results were not achieved in any patients after resective surgery (6 patients) and only 2 patients achieved Class II outcomes after a second epilepsy surgery consisting of neocortical resection. Patients with MTLE after CNS infection were differentiated from the group of neocortical epilepsy by an earlier onset of CNS infection, a prolonged latent period and a higher frequency of meningitis. The characteristic pathology in this group was hippocampal sclerosis and the surgical result was excellent. Neocortical epilepsy following CNS infection usually had no focal lesion on MRI and was associated with a relatively poor surgical result. This study suggested that the surgical outcome was influenced by the type of epileptic syndromes rather than the etiology of seizures. The association of MTLE with the younger age of CNS infections and with meningitis more frequently suggested that the neocortical neurons during infancy or early childhood may be more resistant to the epileptogenesis, or that the CNS infections in patients with MTLE might be milder in severity to cause selective injuries to the hippocampal neurons during their vulnerable stage.

A Case of Congenital Microspherocytosis Requiring Early Splenectomy.

Fan Chen MONG ; Kwang Shin CHO ; Kir Young KIM

Yonsei Medical Journal.1987;28(3):234-242. doi:10.3349/ymj.1987.28.3.234

Microspherocytosis is known as a hallmark of hereditary spherocytosis (HS) which is one of the most common hemolytic anemias with a prevalence of one per 5000, and is inherited as Mendelian dominant. In this disorder, the patient's red cells become spheroidal, osmotically less resistant in the peripheral circulation, and are selectively trapped in the spleen, but survive normally after splenectomy. The exact mechanism for the formation of microspherocytosis has not been elucidated, although extensive investigations demonstrate that HS red cells are intrinsiclly defective and the patient's spleen does "condition" the metabolically abnormal red cells. The authors report here, one case of severe microspherocytosis in which changes in facial bone structure and transfusion dependency are noted, and an early splenectomy is indicated.

Jang Sung KIM ; Sang Am LEE ; Jin Soo KIM

Yonsei Medical Journal.1987;28(3):231-233. doi:10.3349/ymj.1987.28.3.231

One month following carbon monoxide poisoning, a 39 year-old man developed incontinence, memory impairment, disorientation and emotional instability. He was hospitalized 7weeks later, and during hospitalization he exhibited myoclonic movements of the neck and lower limbs. He was given piracetam intravenously for 11 days. The myoclonus was significantly reduced by the third day of treatment and had disappeared by the seventh day. There was no recurrence following cessation of treatment.
