Etiology and Secular Trends in Primary Amenorrhea in 856 Patients: A 17-Year Retrospective Multicenter Study in Korea

Background@#This study was performed to evaluate etiologies and secular trends in primary amenorrhea in South Korea. @*Methods@#This retrospective multi-center study analyzed 856 women who were diagnosed with primary amenorrhea between 2000 and 2016. Clinical characteristics were compared according to categories of amenorrhea (hypergonadotropic/hypogonadotropic hypogonadism, eugonadism, disorders of sex development) or specific causes of primary amenorrhea. In addition, we assessed secular trends of etiology and developmental status based on the year of diagnosis. @*Results@#The most frequent etiology was eugonadism (39.8%). Among specific causes, Müllerian agenesis was most common (26.2%), followed by gonadal dysgenesis (22.4%). Women with hypergonadotropic hypogonadism were more likely to have lower height and weight, compared to other categories. In addition, the proportion of cases with iatrogenic or unknown causes increased significantly in hypergonadotropic hypogonadism category, but overall, no significant secular trends were detected according to etiology. The proportion of anovulation including polycystic ovarian syndrome increased with time, but the change did not reach statistical significance. @*Conclusion@#The results of this study provide useful clinical insight on the etiology and secular trends of primary amenorrhea. Further large-scale, prospective studies are necessary.

Pituitary magnetic resonance imaging abnormalities in young female patients with hypogonadotropic hypogonadism

OBJECTIVE: To elucidate the association between clinical and laboratory characteristics and pituitary magnetic resonance imaging (MRI) abnormalities in young female patients with hypogonadotropic hypogonadism (HH). METHODS: We retrospectively investigated a series of 74 female patients (age range, 14–42 years) with normoprolactinemic HH who underwent pituitary MRI. Pubertal milestones and hormonal features of patients with small pituitary glands (PGs) and space-occupying lesions were compared with those of patients with normal PGs. RESULTS: The overall frequency of abnormal PGs was 35.1%, with space-occupying lesions observed in 8 patients (10.8%), and small PG observed in 18 patients (24.3%). The mean serum gonadotropin level was not different between patients with and without pituitary MRI abnormalities (P>0.05). Space-occupying lesions were not associated with low gonadotropin levels, type of amenorrhea, or presence of secondary sex characteristics. The frequency of space-occupying lesions was higher in patients with interrupted puberty (25.0%) than in patients who did not go through puberty (4.8%) or had a normal puberty (9.8%), but were not statistically significant (P>0.05). Small PG was associated with low gonadotropin levels and type of amenorrhea (P<0.05). CONCLUSION: Clinically significant space-occupying lesions were not associated with low gonadotropin levels, type of amenorrhea, or presence of secondary sex characteristics. However, the frequency of space-occupying lesions was higher in patients with interrupted puberty than in patients who did not go through puberty or who with normal puberty.

Clinical and microbiologic characteristics of vulvovaginitis in Korean prepubertal girls, 2009-2014: a single center experience

OBJECTIVE: To update information on the clinical and microbiologic characteristics of pediatric vulvovaginitis in Korean prepubertal girls. METHODS: A total of 120 girls (aged 0 to 9 years) with culture-confirmed pediatric vulvovaginitis, diagnosed between 2009 and 2014, were enrolled in the study. The epidemiologic and microbiologic characteristics, and clinical outcomes were assessed. Patients with sexual precocity, as well as those who were referred for suspected sexual abuse, were excluded. RESULTS: Girls aged 4 to 6 years were at the highest risk of pediatric vulvovaginitis. Seasonal distribution indicated obvious peaks in summer and winter. Of the 120 subjects, specific pathogens were identified in the genital specimens in only 20 cases (16.7%). Streptococcus pyogenes (n=12, 60%) was the leading cause of specific vulvovaginitis. Haemophilus influenzae was isolated in one patient. No cases presented with enteric pathogens, such as Shigella or Yersinia. A history of recent upper respiratory tract infection, swimming, and bubble bath use was reported in 37.5%, 15.8%, and 10.0% of patients, respectively. Recent upper respiratory tract infection was not significantly correlated with the detection of respiratory pathogens in genital specimens (P>0.05). Of 104 patients who underwent perineal hygienic care, 80 (76.9%) showed improvement of symptoms without antibiotic treatment. Furthermore, the efficacy of hygienic care was not significantly different between patients with or without specific pathogens (P>0.05). CONCLUSION: Specific pathogens were only found in 16.7% of pediatric vulvovaginitis cases. Our results indicate an excellent outcome with hygienic care, irrespective of the presence of specific pathogens.

Severe labial adhesion causing lower genital tract obstruction and bilateral pyosalpinx in an adolescent girl / 대한산부인과학회지

Labial adhesions are extremely rare in adolescent and adult populations, because the etiology of this entity commonly relates to chronic vulvar inflammation or irritation, and is basically associated with low estrogen status. Although a few cases reported urinary retention resulting from severe labial adhesions, there is no report of labial adhesion that precipitates upper genital tract infection in prepubertal and postpubertal females. We present a rare case of severe labial adhesion and consequential lower genital tract obstruction that allegedly causing bilateral pyosalpinx in a 14-year-old adolescent girl who decisively denied sexual experience. The patient was successfully treated with surgical lysis of adhesion and administration of antibiotics.

Abnormal pubertal development in Korean adolescent girls / 대한산부인과학회지

Puberty is the period of first attaining capability of reproduction, and is signed by the appearance of secondary sex characteristics and the occurrence of menarche in females. The timing of puberty is ethnically, sexually and individually variable and is influenced by both genetic and environmental factors. The diagnosis of precocious or delayed puberty is considered when signs of puberty develop before or after 2 standard deviation of the mean age for the onset of puberty. Consequently, a comprehensive understanding of the normal progression of puberty is vital in the evaluation of abnormal pubertal development. In most western countries, the first signs of puberty occur between 8 and 13 years of age. Correspondingly, the recent Korean data have shown that puberty begins in most Korean girls with breast development at the age between 8.7 and 13.9 years. This article reviewed lately published literatures on normal and abnormal pubertal development in Korean adolescent females to delineate features of pubertal disorders in this population.

Non-surgical Treatment of Vaginal Agenesis Using a Simplified Version of Ingram's Method

Non-surgical vaginal dilation is a safe and effective method for the creation of neovagina in the patient with vaginal agenesis. Compared to surgical methods, non-surgical vaginal dilation has the advantage of low morbidity, the creation of a more physiologic vaginal milieu, and no surgical scarring. To overcome some technical limitations of original Frank's method, in 1981 Ingram proposed a modification of the technique that used dilators of gradually increasing size mounted on a bicycle seat stool. Although several studies have shown satisfactory outcomes using Ingram's method, there are some practical difficulties in making and handling the bicycle seat stool. This article reports a case of a 24-year-old woman with Mayer-Rokitansky-Kster-Hauser syndrome whose vaginal agenesis is successfully treated with a simplified version of Ingram's method. This method uses dilators of gradually increasing size mounted on an ordinary chair instead of a bicycle seat stool. When necessary, the patient may use a fulcrum under the dilator.

Uterine Artery Embolization for the Treatment of Symptomatic Fibroids

PURPOSE: The aim of this study was to determine the potential usefulness of uterine artery embolization (UAE) for the management of uterine leiomyoma. MATERIALS AND METHODS: Sixty nine patients (mean age; 40.3 years, age range; 31-52 years) who underwent UAE for symptomatic fibroids (with menorrhagia, dysmenorrhea and bulk-related symptoms) from January 2000 to December 2000 were retrospectively analyzed. The mean follow-up period was 3.5 months (range: 1-8 months). The fibroids ranged in size from 2.0 cm to 13.2 cm with a mean size of 5.8 cm. We performed embolization using polyvinyl alcohol particles (250-710microgram). The improvement of the clinical symptoms was analyzed. Reduction of the uterine and predominant fibroid volumes was assessed using MRI. RESULTS: Symptom improvement for the menorrhagia (87.5%), dysmenorrhea (83.3%) and the bulk-related symptoms (79.2%) was reported. Complications included ovarian failure in four patients (5.8% of the total patients, mean age: 43.3 yrs) and infection in three patients (4.3% of the total patients) who underwent conservative management with intravenous antibiotics and analgesics. The volume reduction rate of the uterus and the predominant fibroids after uterine artery embolization were 36.3% and 56.6%, respectively. CONCLUSION: UAE is a promising new treatment for symptomatic fibroids and may be a valuable alternative to hysterectomy.

Mutation analysis of the KAL Gene in Female Patients with Gonadotropin-Releasing Hormone Deficiency

Isolated gonadotropin-releasing hormone (GnRH) deficiency, including Kallmann's syndrome (KS) and idiopathic hypogonadotropic hypogonadism (IHH), is a congenital disorder, which is characterized by a functional deficit in hypothalamic GnRH secretion. Despite recent advances in the understanding of the pathogenesis of the X-linked form of KS as the identification of the KAL gene (Xp22.3), the genetic basis of the sporadic form in female patients remains unclear. Although most searches for mutations in X chromosome have been reported in males, the newly recognized phenomenon of inheritance, such as genomic imprinting and uniparental disomy, raises the possibility of a female phenotype in the X- linked genetic defect. Here, the molecular study of the coding region of the KAL gene (exon 5 to 14) in 10 unrelated females with KS (n=6) or IHH (n=4) is reported. None of the subjects had familial histories of delayed puberty or hypogonadism. Samples from 4 healthy, unrelated female volunteers were used for identification of polymorphisms. PCR of the 10 exons of the KAL gene was performed on genomic DNA. The PCR products of the 10 exons were subject to single strand conformation polymorphism (SSCP) analysis to identify possible mutations. In an SSCP analysis of the amplified fragments (fragment size: 147 to 302bp), no mutations or polymorphisms were found in any of the 10 patients and 4 controls. In conclusion, it is unlikely that KAL gene mutations are a clinically significant cause of sporadic GnRH deficiency in female patients, indicating the existence of defects in unidentified genes that result in the expression of the phenotypes in females.

Fetal Ovarian Cysts: Sonographic Findings and Natural Courses / 대한산부인과학회잡지

OBJECTIVE: To evaluate sonographic findings and natural courses of fetal ovarian cysts. METHODS: Seven pregnant women (mean, 26 years old; 33 weeks of gestation) diagnosed with having fetal ovarian cysts were evaluated. All were followed-up more than once in utero. We analyzed the location, size, and characteristics (number of locules, thickness of wall/septa, internal echogenecity) of cysts. Internal echogenecity was categorized into 4 types (A=anechoic, B=fluid-fluid level, C=isoechoic portion, D=lace-like). Amount of amniotic fluid, fetal biometry, and other abnormalities were evaluated. RESULTS: In all cases, fetal ovarian cysts were located in lateral or anterior lower abdomen. At time of diagnosis, cysts were 4.2 cm in mean size, round and unilocular. Six cases were type A and the other was type B. On follow-up examination, type A cysts were disappeared (n=1), not changed (n=2), increased in size (n=1), or changed in internal echogenecity (n=2; type B and D). The case categorized into type B at the time of diagnosis was changed to type C later. The case categorized into type A at the time of diagnosis was changed to type B on the first follow-up, but changed to type C on the next examination. Finally, all fetal ovarian cysts were disappeared in utero (n=2) or postnatally (n=5). Fetal biometry and amniotic fluid amount were normal. In all cases, no other abnormalities were detected and full-termed healthy female babies were delivered. CONCLUSION: Fetal ovarian cysts may have various patterns of internal echogenecity although the most common pattern is unilocular anechoic. The size and pattern of internal echogenecity of the fetal ovarian cysts is changeable in utero, however all of them disappear spontaneously in utero or postnatally.

Survival of Trichomonas vaginalis Exposed on Various Environmental Conditions / 감염

OBJECTIVE: Trichomonas vaginalis is the common cause of sexually transmitted diseases. The present study was performed to find the possibility of other transmission mode of T. vaginalis than sexual transmission. METHODS: Survivals of trophozoites suspended in various environmental conditions were measured by haemocytometer after trypan blue staining. Also, drying time of vaginal secretion exposed at different temperatures such as 4 degrees C, 26 degrees C, 30 degrees C were observed. RESULTS: The survival rates of T. vaginalis decreased as the temperatures of tap water increased. The survival rates of trophozoites were less than 10% at 30 min-exposure at 4d degrees C or 15 min-exposure at 26 degrees C water. Hot water above 45 degrees C killed trichomonads in 5 minutes or so. T. vaginalis soaked in water from swimming pool and in cleaning solution deceased in about 5 minutes. When trophozoites were put into urines of six healthy person, the survival rates of T. vaginalis showed less than 10% after 24 hr exposure except KT4. The survival rates of trichomonads were changed according to individual urine on examined day, and isolate of T. vaginalis. The vaginal secretion was put on slide glass and leave alone until complete drying in 4degrees C refrigerator, 26 degrees C and 30 degrees C incubator. For drying of vaginal secretion, it took 70 minutes, 44 minutes and 26 minutes in 4 degrees C refrigerator, 26 degrees C and 30 degrees C incubators, respectively. The survival of trichomonads showed no change until complete dryness of vaginal secretion. T. vaginalis immersed in tap water for 5 minutes, was divided into two or many fragments. Some trichomonads were partially or completely destructed. CONCLUSION: From above results, it is supposed that transmission of T. vaginalis by contaminated fomites such as toilet stool, toilet seats is possible although this type of transmission may not occur frequently.

A Case of Hematometrocolpos due to Complete Septate Uterus and Obstructed Hemivagina associated with Ipsilateral Renal Agenesis / 대한산부인과학회잡지

We report a case of a 13-year-old girl who was noted to have combined malformation of complete septate uterus, obstructed hemivagina and ipsilateral renal agenesis with complaints of dysmenorrhea. Hematometrocolpos was developed in the result of retained menstrual blood since menarche. This rare congenital anomaly is supposed to be derived from disorders of mesonephric and M llerian developement in embryogenesis of female genitouinary tract. An accurate preoperative diagnosis of this syndrome is critical because of the difference in therapeutic strategy and prognosis. Simple and definite treatment of the condition is excision of the obstructed vaginal septum with prompt exit of retained blood. We present here a interesting case of M llerian anomaly in attempt to alert gynecologist to the possible occurrence of such a malformation with a brief review of concerned literatures.

Pediatric Vulvovaginitis: A Study of Clinical and Microbiologic features and the Efficacy of Perineal Hygienic Care / 대한산부인과학회잡지

OBJECTIVES: The purpose of this study was to assess the clinical features, microbiologic results, and the efficacy of perineal hygienic care of pediatric vulvovaginitis. METHODS: Forty-two unselected premenarcheal patients with symptoms or signs of vulvovaginitis who were attended the outpatient pediatric and adolescent gynecology clinic at Pundang CHA General Hospital from August 1997, to September 1999 were systematically interviewed and examined using a standardized format, studied microbiologically, and followed the efficacy of perineal hygienic measures prospectively. RESULTS: The median age of the patients was 4.8 years (range 2.9 years to 10.9 years). Vaginal complaints of 42 patients were discharge(79%), genital pain or irritation(31%), odor(17%), pruritus(14%), and vaginal bleeding(7%). On physical examination, vaginal discharge and vulvar erythema were noted in 17(40%) and 22(52%) patients, respectively. Aerobic bacteria or yeast excluding vaginal normal flora were found in 24 of 42 patients(57%). Convincing evidence of specific pathogens was found in 9 of 42 patients(21%) including one case of pinworm infestation. Isolated pathogens were H. influenza(3), S. pyogenes(2), K. pneumonia(2) and N. gonorrhea(1). No patients were found to have chlamydial infection or trichomoniasis. In 14 patients, risk factors were identified such as swimming(14%), bubble bath(5%), sexual abuse(5%), genital trauma(5%) and foreign body(2%). After two weeks instructions of perineal hygienic care, 26(62%) of 42 patients revealed complete resolution of symptoms and signs of vaginitis without antibiotics. Efficacies of perineal hygienic care were 94%(17/18) in the patients with normal flora alone, 60%(9/15) in the patients with organisms suspected for nonspecific infection and 0%(0/9) in the patients with specific pathogens(p<0.05). CONCLUSION: Majority(62%) of the pediatric patients with symptoms or signs of vulvovaginitis were cured with perineal hygienic care alone. And the efficacy of hygienic measure were higher in the patients without specific pathogens(79%, 26/33). Therefore, proper physical examination, microbiologic study and appropriate instructions of perineal hygienic care were more important than empirical antibiotic treatment in initial management of pediatric vulvovaginitis.

Fertility outcome of Laparoscopic Tubal Reanastomosis / 대한산부인과학회잡지

OBJECTIVE: Our purpose was to evaluate the pregnancy outcome and the advantages of laparoscopic tubal reanastomosis. METHOD: During 16 months, January 1996 to April 1997, thirty-two patient had underwent laparoscopic tubal reanastomosis in Pudang CHA General Hospital. The mean age of the patients was 36.1+/-4.3 years(mean+/-SD; range 26 to 47 years). RESULT: The intrauterine pregnancy rate of laparoscopic tubal reanastomosis was 72.4%(21/29). Data comparing laparoscopic procedure retrospectively to tubal reversal by laparotomy was also evaluated. The mean interval from operation to pregnancy was similar in the two groups (p=0.9). The operation time was sigoificantly longer for laparoscopy (215.3+/-35.5 minutes) than for laparotomy(159.7+/-52.3 minutes). Nevertheless, the intensity of postoperative pain was lower (p<0.05) in patient who underwent laparoscopy than in patient who underwent laparotomy. Also, the mean hospital stay (3.6+/-2.3 days for laparoscopy, 6.1+/-0.5 days for laparotomy) was shortened(p<0.05) after laparoscopy compared with laparotomy. CONCLUSION: Laparoscopic tubal reanastomosis may offer the benefits of lower postoperative pain and shorten recovery time in comparison with laparotomy. Therefore, considering the high pregnancy rate in minimal follow up period of 6 month, laparoscopic tubal reanastomosis could be an alternative procedure to microsurgical laparotomy in patients requesting reversal of sterilization.

A Study on the Calcium-Binding Protein in Gallbladder Bile / 대한내과학회지

OBJECTIVES: Calcium salts are usually present in the center of all types of gallstones, including pure cholesterol stones. It has been postulated that precipitation of calcium salts might act as a nidus for gallstone formation. Our goal was to determine whether a calcium-binding protein was present in bile and whether this protein has any calcium-binding properties. METHODS: Calcium-binding moiety was obtained by addition of CaC12 into the gallbladder bile. Calcium-binding protein was identified by SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). The capacity to bind calcium was confirmed by autoradiography with 45Ca++. RESULTS: We identified a protein(M.W.

Tumor Marker Study of Pure Pancreatic Juice in Patient with Pancreatic Diaeases / 대한소화기내시경학회지

Several reports have described the usefulness of tumor markers detected in pancreatic juice for diagnosis of pancreatic cancer. We performed this study to evaluate the usefulness of tumor markers in pure pancreatic juice collected by duodenoscopic cannulation of pancreatic duct before and after injection of secretin. From April 1993 to July 1995, 8 cases of pancreatic cancer, 5 cases of benign pancreatic lesions, and 5 cases of benign biliary diseases without pancreatic lesion were involved. CEA and CA 19-9 immunoreactivity were measured by radioimmunoassay. Concentrations of CA 19-9 in pure pancreatic juice were significantly higher in patients with pancreatic cancer(median value; 3582, range 88.4-10410 IU/ml) than in control patients(median value 231, range 30.4-682 IU/ml)(p0.05). There was no significant correlation between levels of CA19-9, CEA in pancreatic juice and those levels in serum. The amounts of juice collected by duodenoscopic cannulation in patients with pancreatic cancer were 1.5+/- 0.9ml during 5 minutes before infusion of secretin, 11.3+/- 3.9ml, 10.8+/- 4.0ml, 10.6+/- 4.0ml in 5 minute interval after infusion of secretin. These results indicated that measurement of CA19-9 in pure pancreatic juice may be used as a marker for pancreatic cancer. Adequate amount of pancreatic juice was collected by duodenoscopic cannulation for evaluation of tumor marker, enzyme studies and cytology.

Choledochal Cyst and Anomalous Union of Pancreaticobiliary Duct in the Adult / 대한소화기내시경학회지

Background/Aims: Choledochal cyst is a congenital dilatation of extra- or intrahepatic bile duct. Recently, anomalous union of pancreaticobiliary duct(AUPBD) is supposed to be one of the major causes of choledochal cyst. The aims of this study are to assess the association ratio of AUPBD in choledochal cyst and whether the AUPBD in choledochal cyst have a clinical significance. Methods: The study subjects were 35 adult patients who were diagnosed by ERCP in Asan Medical Center from August, l990 to July, 1995. We have classified the type of choledochal cyst and AUPBD according to Todani and Kimura, respectively.

The Frequency of Phasic Wave Confraction is Variable during Long - Term Sphincter of Oddi (SO) Manometry / 대한소화기내시경학회지

Objectives: The sphincter of Oddi(SO) manometry via transpapillary route is performed usually for a period of several minutes. To investigate whether there is a considerable variation in the manometric measurements of SO over a longer period of time, we have performed long-term manometry of SO via transpapillary(n=5) as well as percutaneous(n=7) route. Methods: Transpapillary manometry of SO was carried out by conventional low- compliant continuously perfused techni~que. The location of the manometric catheter was maintained at the same level by observing the video monitor. SO manometry and the duodenal migrating motor complex(MMC) was simuitaneously measured with specially designed catheter via pereutaneous route. Results: The mean recording time was 41 minutes(range 11-72 minutes). The frequency of phasic contractions of SO varied from 0 to 12/min. Throughout the whole recording period, high-frequency contractians(over 8/min) were noted in 14.9 % of the time. In the eases of percutaneous transductal SO manometry, the periods of high-frequency contractions coincided with the phase III of duodenal MMC. The interval between the first high-frequency contractions and the second was 47 minutes. The mean duration of high-frequency contractions was 6 minutes and 4~2 seconds. There as no significant change in the amplitude, basal pressure and contraction sequence among the various periods of frequencies. Conclusions: Long-term continuous recording of SO manometry via transpapillary and percutaneous route showed that the contraction frequency of SO was not constant and tachyoddia appearde periodically. In the interpretation of tachyoddia, it is necessary to consider the period of phase III of the duodenal MMC.

Pancreas Divisum, Choledochal Cyst and Pancreatic Stones in a 50-year-old Man / 대한소화기내시경학회지

A 50-year-old man presented with acute pancreatitis. Abdominal CT showed cystic dilatation of common bile duct and diffuse dilatation of pancreatic duct. ERCP showed pancreas divisum, choledochal cyst and pancreatic duct stones. Minor papilla sphincterotomy and insertion of nasopancreatic tube were performed for drainage of dorsal pancreatic duct. And then, he underwent Whipples operation for excision of choledochal cyst and decompresion of dorsal pancreatic duct.
