RESUMO

INTRODUCTION: Amenorrhea induced decrease of hormones is associated with cognitive impairment. This study aimed to evaluate hippocampal functional connectivity patterns in chemotherapy-induced amenorrhea (CIA) breast cancer (BC) patients, to evaluate the relationship between the functional connectivity features and hormone levels. METHOD: Neuropsychological test, functional magnetic resonance imaging, and assessment of hormone levels were conducted in 21 premenopausal BC patients before chemotherapy (t0 ) and 1 week after completing chemotherapy (t1 ). Twenty matched healthy controls (HC) were also included and underwent the same assessments at similar time intervals. Mixed effect analysis and paired t-test were used to compare differences in brain functional connectivity. RESULTS: Voxel-based paired t-tests revealed increased functional connectivity of the right and left hippocampus with the left fusiform gyrus, inferior and middle temporal gyrus, inferior occipital gyrus, left lingual gyrus, and parahippocampal gyrus after chemotherapy (p < .001) in CIA patients. Repeated measures analysis revealed significant group-by-time interactions in the left hippocampus with the bilateral fusiform gyrus, right parahippocampal gyrus, left inferior temporal gyrus, and left inferior occipital gyrus (p < .001). Premenopausal BC patients had no significant differences in cognitive function compared with HC at baseline. However, the CIA patients had high levels of self-rating depression scale, self-rating anxiety scale, total cholesterol, and triglycerides. Further, the CIA patients showed significant differences in hormone and fasting plasma glucose levels and cognitive performances between t0 and t1 (p < .05). Functional connectivity changes between the left hippocampus and the left inferior occipital gyrus was negatively correlated with E2 and luteinizing hormone changes (p < .05). CONCLUSION: The CIA patients had cognitive dysfunction mainly in memory and visual mobility. Chemotherapy may affect hippocampal-posterior cortical circuit which mediates visual processing in CIA patients. Moreover, E2 may be involved in this process.

RESUMO

Background/Purpose: A prolactinoma is the most common pituitary adenoma, but it is relatively rare in childhood and adolescence. There is only limited research about the clinical spectrum, treatment, and outcomes of prolactinomas in childhood and adolescence. In this single-center cohort study, we assessed the clinical, hormonal, and neuroradiological characteristics and therapeutic outcomes of children and adolescents with prolactinomas. Methods: This retrospective cohort study included 25 patients with prolactinomas diagnosed before 19 years of age, who presented at Samsung Medical Center during a 15-year period (March 2005 to August 2019). Results: The median age at diagnosis was 16.9 (range 10.1-18.5) years, and 80% of the patients were female. The common clinical manifestations at diagnosis were galactorrhea (10/20, 50%) and amenorrhea (9/20, 45%) among females and visual field defects (3/5, 60%) and headaches (2/5, 40%) among males. In our cohort, macroadenomas accounted for 56% of cases, and the rate of overall responsiveness to dopamine agonists (DAs) was 56% (10/18). Male gender, the prolactin (PRL) level at diagnosis, and the presence of panhypopituitarism were positively correlated with maximum tumor diameter (r = 0.443, P = 0.026; r = 0.710, P < 0.001; and r = 0.623, P = 0.001, respectively). After the trans-sphenoidal approach (TSA), 53% (8/15) of patients showed normalization of the PRL level. Three patients, who underwent gamma knife surgery (GKS) owing to either resistance or intolerance to DAs or recurrence after the TSA, achieved a normal PRL level accompanied with marked tumor reduction and symptom remission. Conclusions: A macroprolactinoma is more prevalent than a microprolactinoma in children and adolescents than in adults. Male gender, increased PRL levels, and the presence of panhypopituitarism at diagnosis are closely related to macroprolactinomas in children and adolescents.

RESUMO

OBJECTIVE: Since features of polycystic ovary syndrome (PCOS) have been found to be prevalent in women with functional hypothalamic amenorrhea (FHA), we wished to determine what happens to these features after recovery of menstrual function in FHA Design: Prospective cohort study. Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied. METHODS: Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied. We measured serum estradiol, LH, FSH, testosterone, DHEAS, anti-Mullerian hormone (AMH), body mass index, and ovarian morphology on transvaginal ultrasound. RESULTS: At baseline, 12 of the 28 women (43%) had increased AMH (>4.7 ng/mL), and higher testosterone and larger ovaries compared to the other 16 women with normal AMH. One year after recovery of menstrual function, in the 12 women with increased AMH, serum AMH, testosterone and ovarian size decreased, while LH and estradiol increased. At one year, only one of the 12 women in the high AMH group developed clinical features of PCOS. CONCLUSIONS: In the majority of women with FHA who have PCOS-like features, these features may be due to the hypothalamic state and appear to be reversible. Few women may develop clinical PCOS after recovery.

RESUMO

Lymphocytic infundibulo-neurohypophysitis is a rare disorder. We report the case of a 29 year-old woman with diabetes insipidus and amenorrhea, in whom the magnetic resonance imaging demonstration of a pituitary stalk lesion was intermittent. We suggest that, in patients with endocrine dysfunction and positivity of circulating antipituitary antibodies at high title, magnetic resonance imaging should be repeated after few months, if negative.

RESUMO

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital abnormality characterised by varying degrees of aplasia or hypoplasia of the uterus and vagina. Very rarely, leiomyomas or adenomyosis can develop in the Müllerian remnant tissue or rudimentary uterus. We present a case of a 43-year-old woman with MRKH syndrome, who presented with primary amenorrhoea and lower abdominal pain. On examination, a large pelvic mass was palpated and a provisional diagnosis of ovarian tumour was made. MRI showed multiple large leiomyomas arising from the Müllerian remnant tissue, and chronic torsion of the right ovary.

RESUMO

INTRODUCTION: Functional hypothalamic amenorrhoea (FHA) is a condition characterised by the absence of menses due to suppression of the hypothalamic-pituitary-ovarian axis. OBJECTIVE: The purpose of the study was to estimate uterine and ovarian sizes in adolescents with FHA and to compare these results with findings in peers having regular menstrual cycles. DESIGN: Prospective case-controlled study. SETTINGS: Vilnius University Hospital Santariskiu Klinikos, Lithuania. PATIENTS: Lithuanian adolescents--45 with FHA and 40 comparison group participants. MAIN OUTCOME MEASURES: We assessed ultrasound measurements of internal reproductive organs, levels of luteinising hormone, follicle-stimulating hormone, prolactin, oestradiol and calculated body mass index (BMI). RESULTS: The mean age of the participants was 16.3 ± 1.2 years, the mean age after menarche--3.6 years. In adolescents with FHA the BMI was 17.8 ± 1.8 kg/m(2) and 20.4 ± 1.4 kg/m(2) in the comparison group, p < 0.001. The uterine volume (14.7 ± 6.3 cm(3) vs 31.7 ± 10.6 cm(3), p < 0.001), cervical length (2.3 ± 0.4 cm vs 2.6 ± 0.5 cm, p = 0.03), volume of both ovaries (9.3 ± 3.6 cm(3) vs 13.8 ± 4.3 cm(3), p < 0.001) and levels of LH (2.70 ± 2.59 vs 6.01 ± 2.44, p < 0.001) were significantly lower in girls with FHA. A significantly positive correlation between volume of uterus and levels of LH (r = 0.415; p < 0.001) was found. We identified a positive correlation between uterine volume, uterine corpus length, cervical length, ovarian volume and weight, BMI. CONCLUSIONS: In adolescents with FHA the dimensions of uterus and ovaries were smaller than in girls having regular menstrual cycles. Our study confirmed the influence of oestrogen on uterus size: oestrogen deficiency causes a reduction in uterine size. Uterine size and ovarian size correlate positively with BMI.

RESUMO

CONTEXT: Antimüllerian hormone (AMH) and insulin-like factor 3 (INSL3) represent ovarian functional markers of granulosa and theca cells, respectively. OBJECTIVE: We conducted a prospective study to investigate AMH and INSL3 plasma levels in 3 groups of women with polycystic ovary syndrome (PCOS) classified according to menstrual cyclicity pattern and their relationship with ovarian morphology and hormonal levels. DESIGN AND PARTICIPANTS: AMH and INSL3 were measured in a cohort of 57 patients with PCOS, divided into 3 groups according to menstrual status: eumenorrheic (PCOS-E, n = 15), oligomenorrheic (PCOS-O, n = 25), and amenorrheic (PCOS-A, n = 17). Clinical and endocrine characteristics and ovarian morphology were compared among the groups. Twenty-seven age- and weight-matched women without hyperandrogenism were included as controls. RESULTS: According to the menstrual pattern, the women with PCOS-A and PCOS-O had higher INSL3 levels with respect to the control women (P = .025 and P = .004, respectively) and higher but not significant INSL3 levels compared with those of the women with PCOS-E. AMH levels were significantly higher in women with PCOS-A and PCOS-O with respect to those in women with PCOS-E (P < .001 and P < .001, respectively) and control women (P < .001 and P < .001, respectively). Interestingly, a significant positive correlation was found between INSL3 and AMH blood levels in all women with PCOS (R = 0.43; P = .002) and across the groups (R = 0.41; P < .001). CONCLUSIONS: INSL3 and AMH levels are significantly correlated with each other in women with PCOS, and they are significantly increased, particularly in the presence of amenorrhea and oligomenorrhea. INSL3 and AMH may reflect a dysfunction of PCOS thecal and granulosa cells, which are responsible for the increased androgen production and chronic anovulation of this condition.

RESUMO

PURPOSE: To compare the incidences of symptom recurrence and permanent amenorrhea following uterine artery embolization (UAE) for symptomatic fibroid tumors in patients with type I and II utero-ovarian anastomoses (UOAs) with versus without ovarian artery embolization (OAE). MATERIALS AND METHODS: A retrospective, institutional review board-approved study of 99 women who underwent UAE for symptomatic fibroid tumors from April 2005 to October 2010 was conducted to identify patients who had type I or II UOAs at the time of UAE. Based on the embolization technique, patients were categorized into standard (ie, UAE only), combined (ie, UAE and OAE), and control (patients without UOAs who underwent UAE) groups. Data collected included patient characteristics, procedural technique and findings, symptom recurrence, secondary interventions, and permanent amenorrhea. Statistical analysis was performed with the Fisher exact test, with significance reached at P < .05. RESULTS: Twenty patients (20.2%; mean age, 46.9 y ± 6.3) had type I (n = 3) or II (n = 17) UOAs. Thirteen (65%) underwent UAE only (standard group) and seven (35%) underwent UAE and OAE (combined group). There were no significant differences between groups in demographics or in the incidence of permanent amenorrhea after procedures (follow-up, 561 d ± 490). There was a significantly higher incidence of symptom recurrence in the standard group compared with the control group (P = .01), with no differences between combined and control groups (P = 1). CONCLUSIONS: There were no statistical differences in permanent amenorrhea rates in the groups studied, with significantly higher symptom recurrence rates observed when OAE was not performed in the setting of UOA.

RESUMO

Although there is a long list of syndromes with phocomelia, there are only two syndromes in which there is concurrent pelvic dysplasia and phocomelia: Al-Awadi-Raas-Rothschild syndrome (AARRS) and Schinzel phocomelia syndrome (SPS). Currently, there is a diagnostic confusion between the two syndromes and both have the same MIM entry (MIM 276820). We believe that the two syndromes are different entities and we also believe that the limb defect in SPS is a "true" phocomelia while the limb defect in AARRS is an "apparent" phocomelia. "Apparent" phocomelia describes the most severe form of ulnar ray deficiency in which there is absent ulna with radio-humeral synostosis. "Apparent" phocomelia is diagnosed radiologically by three radiological features: the apparently single bone occupying the arm/forearm appears relatively long, the area of radio-humeral synostosis will have thicker cortex with or without slight angulation, and the lower end of the bone resembles the lower end of a radius and not a humerus. In this paper, we present two new cases of AARRS from two different Saudi Arabian tribes: one case with R292C mutation of WNT7A with bilateral "apparent" phocomelia and a second case with a novel c.814G>T mutation of the WNT7A gene (resulting in wnt7a protein truncation at position 272) with unilateral "apparent" phocomelia. We reviewed previously reported cases of AARRS and SPS to further delineate the differences between these two syndromes. We make the argument that these two syndromes are two different entities and hence require two different MIM entries.

RESUMO

OBJECTIVE: A case report of a patient diagnosed with Camurati-Engelmann Disease (CED) in association with the functional hypothalamic amenorrhea disturbances. CED is a very rare genetically determined disorder classified as a type of bone dysplasia. DESIGN: Case report. SETTING: Department of Gynecological Endocrinology, 3rd grade Medical University Hospital. PATIENT: Twenty-one years old female patient with CED admitted to the hospital because of primary amenorrhea. Her history revealed skeletal deformities and hearing impairment. METHODS: Clinical examination, ultrasound, laboratory evaluations (including serum gonadotropins (FSH, LH) at basal state and after stimulation with gonadotropin-releasing hormone, serum basal estradiol) radiological studies (X-ray of the head, the lumbar spine and lower extremities; a computed tomography of the head), G-banding karyotype, polymerase chain reaction and DNA sequencing. Hormonal serum evaluations were made using an enzyme-linked immunosorbent assay. The exon 4 of the transforming growth factor beta 1 gene was amplified by a polymerase chain reaction and the product was directly sequenced. RESULTS: The hormonal analysis was characteristic for the hypogonadotropic hypogonadism. Radiological and molecular analyses confirmed CED diagnosis. CONCLUSIONS: The hypothalamic amenorrhea in a patient with CED may be explained as a consequence of fat hypotrophy and very low body mass index. Therefore, impairment within hypothalamic-pituitary axis in patients with CED should be treated with special attention.

RESUMO

CONTEXT: In the general population, about 30% of asymptomatic women have polycystic ovary-like abnormalities (PCO-L), i.e. polycystic ovarian morphology (PCOM) at ultrasound and/or increased anti-Müllerian hormone (AMH) serum level. PCOM has also been reported in 30-50% of women with functional hypothalamic amenorrhea (FHA). OBJECTIVE: The aim of this study was to verify whether both PCOM and excessive AMH level indicate PCO-L in FHA and to elucidate its significance. DESIGN: We conducted a retrospective analysis using a database and comparison with a control population. SETTING: Subjects received ambulatory care in an academic hospital. PATIENTS: Fifty-eight patients with FHA were compared to 217 control women with nonendocrine infertility and body mass index of less than 25 kg/m(2). INTERVENTIONS: There were no interventions. MAIN OUTCOME MEASURES: We measured serum testosterone, androstenedione, FSH, LH, AMH, and ovarian area values. The antral follicle count (AFC) was used as a binary variable (i.e. negative or positive) because of the evolution of its sensitivity over the time of this study. The ability of these variables (except AFC) to detect PCO-L in both populations was tested by cluster analysis. RESULTS: One cluster (cluster 2) suggesting PCO-L was detected in the control population (n = 52; 24%), whereas two such clusters were observed in the FHA population (n = 22 and n = 6; 38 and 10%; clusters 2 and 3, respectively). Cluster 2 in FHA had similar features of PCO-L as cluster 2 in controls, with higher prevalence of positive AFC (70%) and PCOM (70%), higher values of ovarian area and higher serum AMH (P < 0.0001 for all), and testosterone levels (P < 0.01) than in cluster 1. Cluster 3 in FHA was peculiar, with frankly elevated AMH levels. In the whole population (controls + FHA), PCO-L was significantly associated with lower FSH values (P < 0.0001). CONCLUSION: PCO-L in FHA is a frequent and usually incidental finding of unclear significance, as in controls. The association of PCO-L with hypothalamic amenorrhea should not lead to a mistaken diagnosis of PCOS.

RESUMO

CONTEXT: Functional hypothalamic amenorrhea (FHA) related to hypoestrogenism and hormonal status may influence skeletal homeostasis and body composition. The study aimed to evaluate hormones concentrations, body composition and bone strength in FHA cases. PATIENTS AND METHODS: Total body scans using DXA method (DPX-L, GE Lunar) were performed in a group of 27 women aged 21.8 years ± 3.9 with FHA related to weight loss. References of healthy control subjects were used to calculate Z-scores (age and gender matched), SD-scores (height and gender matched), and SDs-scores (weight and gender matched). Whole skeleton bone mineral content (TBBMC, g) and density (TBBMD, g/cm(2)), lumbar spine (L2-L4) bone mineral density (SBMD; g/cm(2)), lean body mass (LBM, g) and fat mass (FM, g) were investigated. Relative bone strength index was calculated as the TBBMC/LBM ratio. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, testosterone, and prolactin (PRL) concentrations were assayed to characterize hormonal profile of FHA cases. RESULTS: Hormonal evaluation in patients with FHA revealed significantly decreased serum concentrations of gonadotropins and estradiol. Serum LH concentrations were 1.47 ± 0.89 mIU/ml, FSH 4.44 ± 1.94 mIU/ml. Estradiol concentrations in serum were 27.08 ± 13.10 pg/ml. As evidenced by Z-scores, FHA cases had decreased SBMD, TBBMD and TBBMC Z-scores of -1.23 ± 0.90 (p < 0.0001), -0.72 ± 0.86 (p < 0.001), and -0.90 ± 1.40 (p < 0.01), respectively. Reduced FM, LBM and FM/LBM ratio Z-scores of -1.80 ± 2.28 (p < 0.001), -0.59 ± 1.49 (p < 0.05) and -0.74 ± 1.55 (p < 0.05), but not TBBMC/LBM Z-score of -0.54 ± 2.14 (ns) were noted in FHA cases compared with healthy control cases. TBBMC, TBBMD, TBBMC/LBM when BH- or BW-matched were normal as evidenced by SD-scores and SDs-scores. SBMD remained reduced when BH-matched (SD-score = -0.40 ± 0.86; p < 0.05) whereas FM and FM/LBM were lower than expected in healthy, both compared to BH- and BW-dependent references. The length of amenorrhea in months negatively correlated with SBMD Z-score (R = -0.39, p < 0.05), and SD-scores for SBMD (R = -0.48), TBBMD (R = -0.43), TBBMC (R = -0.46) (all p < 0.05) and positively with SDs-scores for FM (R = 0.44, p < 0.05). CONCLUSION: Patients with FHA were characterized by lower concentrations of serum FSH, LH and estradiol concentrations. Moreover, FHA cases had decreased FM and an imbalanced relationship between BW, FM, and LBM. Despite reduced BMD and BMC, bone strength was not significantly affected by FHA.

RESUMO

BACKGROUND: The main cause for discontinuation of depot medroxyprogesterone acetate (DMPA) use is irregular menstrual bleeding. The exact pathophysiological mechanisms of irregular bleeding have remained unclear. Transvaginal Doppler is a non-invasive method for studying changes in blood flow which may highlight the underlying pathology in those cases with irregular uterine bleeding. The aim of this study was to quantify the uterine and subendometrial microvasculature in DMPA users with irregular bleeding pattern in comparison to DMPA users with amenorrhea. STUDY DESIGN: This is a case control study. Forty users of DMPA were divided into two groups: one group included 20 users with irregular uterine bleeding and the second group included 20 amenorrheic users. Pulsatility index (PI) and resistance index (RI) of uterine and subendometrial blood vessels were determined. Power Doppler Energy was used to quantify the signal percentage of the subendometrial area. RESULTS: There is significant reduction of PI and RI in the uterine artery and subendometrial microvasculature in cases of irregular uterine bleeding. CONCLUSION: Irregular uterine bleeding with DMPA associated with increased perfusion of uterine and subendometrial blood vessels.

RESUMO

OBJECTIVES: The aim of the present study was to characterize women with premature ovarian failure (POF) by their ovarian ultrasonographic appearances using transabdominal technique to establish the relationship to clinical, hormonal status, and genetic analysis. PATIENTS AND METHODS: We studied a cohort of 80 patients suffering from POF. The surface of the ovary was calculated and we identified the detection or not of follicles. RESULTS: The detection of the two ovaries by ultrasound was positive in 33 patients; only one ovary was identified in seven patients; none was noted in 40 patients. The surface of the ovaries ranged between 0.74 et 5.92 cm(2) (2.2+/-1.13 cm(2)). Ultrasonography identified follicles in 23 patients (28.75%). The presence of follicles suggested at ultrasonography was detected in 14 cases (70%) in normal-sized ovaries (> or =2 cm(2)) and in nine cases (45%) in small-sized ovaries (p=0.1). No significative statistical difference was found between the ultrasonographic appearances and the type of amenorrhea, pubertal development, hormonal status (estradiol, testosterone and delta-4-androstendione) and the chromosomal analysis. CONCLUSION: The clinical and hormonal status and the genetic analysis can't predict the presence or not of follicles in the ovaries of patients with POF.

RESUMO

OBJECTIVES: To determine if amenorrheic women with polycystic ovary syndrome (PCOS) demonstrate ultrasonographically detectable changes in follicle population. METHODS: Sixteen women with PCOS reporting the absence of menses for more than 3 months were enrolled in the study. Subjects had a physical examination, fasting blood tests and two transvaginal ultrasound scans spaced 1 month apart. In cases where evidence of a morphologically dominant follicle (≥ 10 mm in diameter) occurred, subsequent ultrasound scans were performed to determine the fate of the dominant follicle. Differences in total follicle population, maximum follicle diameter and clinical, hormonal and metabolic features were determined. RESULTS: Forty-four percent of subjects showed changes in follicle population of 6-10 follicles and 37% showed changes in follicle population of > 10. Maximum follicle diameters ranged between 5.4 and 33.0 mm. Four subjects demonstrated follicle diameters ≥ 10 mm. Of those who developed dominant follicles, two subjects ovulated, one subject developed a persistent anovulatory follicle and the dominant follicle regressed in the remaining subject. Diagnostic criteria for PCOS were similar among women that did or did not develop dominant follicles (menstrual cycle length, P = 0.880; hirsutism score, P = 0.809; free androgen index, P = 0.991; total follicle count, P = 0.199). However, lower glycosylated hemoglobin (P = 0.047) and insulin levels (P = 0.049) and better insulin sensitivity (P = 0.048) were noted in women who attained dominant follicles. CONCLUSION: Amenorrheic women with PCOS demonstrate changes in follicle population that are consistent with active follicle growth and regression despite prolonged periods of anovulation. Morphologic selection occurs in amenorrheic women and attainment of dominant follicles is associated with improved metabolic status.

RESUMO

OBJECTIVE OF STUDY: To document sonographically identifiable causes of vaginal bleeding in secondarily amenorrhoeic women of child bearing age. METHODS: A retrospective study of ultrasonographic findings among 102 secondarily amenorrhoeic women of childbearing age with vaginal bleeding was carried out. Ultrasound scan was carried using Siemens Sonoline SL1 equipment with 3.5MHz and 5.0MHz transducers RESULTS: 75(73.2%) patients had pregnancy-related conditions, 14(13.7%) had normal, non-pregnant uteri while the remaining 13 (12.8%) had other gynaecological conditions namely pelvic inflammatory disease (PID), uterine fibroids and ovarian masses. Though pregnancy-related conditions are the major causes of vaginal bleeding in amenorrhoeic women of childbearing age, PID, fibroids and ovarian masses are possible findings. CONCLUSION: Ultrasound examination is vital in the elucidation of vaginal bleeding in amenorrhoeic women. Pregnancy related conditions are not the only significant cause of amenorrhoea complicated by vaginal bleeding.

RESUMO

Pelvic pain is a common indication for ultrasound examinations in female pediatric patients. Many pathological processes affect the female pelvis in childhood. Knowledge of the normal ultrasound appearance of the pelvic organs is the basis for the recognition of pathologic findings. Pelvic pain in children is a nonspecific clinical finding often prompting use of ultrasound. Other indications for pelvic ultrasound in female children include workup of cysts seen on fetal ultrasound, urogenital malformations in newborns, precocious puberty, vaginal discharge or abnormal bleeding, and amenorrhea. Knowledge of differential diagnosis for disease processes of the female pelvic organs is essential. Ultrasound is the imaging modality of choice for evaluating the pediatric female pelvis.
