ABSTRACT

This study aimed to assess the combined clinical and ultrasound criteria as a diagnostic tool for screening the Y chromosome related to primary amenorrhea. This cross-sectional study involving 59 subjects was taken from medical records at the Reproductive Immunoendocrinology Polyclinic of Cipto Mangunkusumo General Hospital, Jakarta, Indonesia. The medical records of subjects were then cross-checked with karyotyping analysis results. Sensitivity, specificity, and predictive values were analyzed to assess the criteria. Two subjects were presented with a Y chromosome, and one without a Y chromosome was misclassified into another group. After analysis, we found that combined clinical and ultrasound criteria could predict the Y chromosome related to primary amenorrhea with 95.9% accuracy, with sensitivity and specificity of 80% and 97.96%, respectively. Combined clinical and ultrasound criteria (introduced as Kanadi Sumapraja Criteria) could be used as a diagnostic tool for screening a Y chromosome related to primary amenorrhea.

ABSTRACT

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.

ABSTRACT

Female Athlete Triad, initially described as the association of disordered eating, amenorrhea and osteoporosis, was further redefined to focus on low energy availability (EA), which has a central role in development of hypoestrogenism and low bone mineral density (BMD). However, the contribution of each variable, that is, low EA and hypoestrogenism, for bone derangements is still an open question. To evaluate body composition and bone status in long-distance triathletes without hypoestrogenism, as compared to non-athletes, using DXA and HR-pQCT, and the influence of EA. Population comprised 23 triathletes who had completed at least one long-distance race in the previous year, and 17 non-athletic healthy controls. The athletes denied previous oligo-amenorrhea and had spontaneous regular menses or were on hormonal contraceptives. Control patients also had regular menses. Energy deficiency (low EA) was defined as energy intake below the recommended level for athletes, that is, 45 kcal/kg free fat mass/day. Only femoral neck BMD Z-score measured by DXA trended higher in athletes (p = 0.05), whereas high-resolution peripheral quantitative computed tomography detected significantly higher values of entire bone and trabecular bone area, cortical perimeter, trabecular vBMD and trabecular bone volume/tissue volume, and lower trabecular separation and trabecular inhomogeneity in athletes. No difference was found between athletes with spontaneous menses and those on hormone contraceptives in respect to all parameters. The effects of exercise on bone were not so pronounced in athletes with low EA, although they still had better bone parameters than controls. Stress fractures were reported by 4:12 athletes with low EA and by 2:11 athletes with adequate EA. Long-distance female triathletes without hypoestrogenism show higher values of cortical perimeter, bone area, volumetric density and trabecular microstructure, but low EA interferes with exercise-associated bone effects. These innovative findings reinforce the importance of adequate EA in female athletes to guarantee skeletal health.

ABSTRACT

This is a pictorial review on the radiological approach to patients with amenorrhea using a level-based framework. The prevalence of amenorrhea is 3 to 4% with wide-ranging causes involving multiple clinical disciplines. Normal menstruation depends on complex coordinated hormonal functions of the hypothalamic-pituitary-ovarian axis exerting its effect on an intact uterine end-organ and outflow tract. A disruption of any of these factors may result in amenorrhea. Categorizing the causes of primary and secondary amenorrhea into uterine, ovarian/gonadal, and intracranial levels provides a logical framework for its evaluation. A systematic level-based approach by targeted ultrasound of the pelvic structures is suggested, with different aims in primary versus secondary amenorrhea. Pelvic sonographic findings of various conditions within the uterine and ovarian/gonadal levels are illustrated. Conditions due to an intracranial cause result in downstream effects on the uterus and ovaries and can often be suspected based on a combination of clinical assessment, ultrasound findings, and laboratory investigations. By correlating pelvic ultrasound findings with underlying pathology, the clinical radiologist is able to provide useful diagnostic information in the management of these patients.

ABSTRACT

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.

ABSTRACT

Objective: We have reported low bone mineral density (BMD), impaired bone structure, and increased fracture risk in participants with anorexia nervosa (AN) and normal-weight oligoamenorrheic athletes (OAs). However, data directly comparing compartment-specific bone parameters in participants with AN, OAs, and controls are lacking. Design: A total of 468 female participants 14 to 21.9 years old were included: 269 with AN, 104 OAs, and 95 normal-weight eumenorrheic controls. Dual-energy x-ray absorptiometry was used to assess areal BMD (aBMD) of the whole body less head (WBLH), spine, and hip. High-resolution peripheral quantitative computed tomography was used to assess volumetric BMD (vBMD), bone geometry, and structure at the non-weight-bearing distal radius and weight-bearing distal tibia. Results: Participants with AN had lower WBLH and hip aBMD z scores than OAs and controls (P < 0.0001). Participants with AN and OAs had lower spine aBMD z scores than controls (P < 0.01). At the radius, total and cortical vBMD, percentage cortical area, and thickness were lower in the AN and OA groups than in controls (P ≤ 0.04); trabecular vBMD was lower in participants with AN than controls. At the tibia, participants with AN had lower measures for most parameters compared with OAs and controls (P < 0.05); OAs had lower cortical vBMD than controls (P = 0.002). Participants with AN and OAs had higher fracture rates than controls. Stress fracture prevalence was highest in OAs (P < 0.0001); nonstress fracture prevalence was highest in participants with AN (P < 0.05). Conclusion: AN is deleterious to bone at all sites and both bone compartments. A high stress fracture rate in OAs, who have comparable WBLH and hip aBMD measures to controls, indicates that BMD in these women may need to be even higher to avoid fractures.

ABSTRACT

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.

ABSTRACT

Clinicians currently use different low-weight cut-offs both to diagnose anorexia nervosa (AN) and to determine AN severity in adolescent girls. The purpose of this study was to evaluate the clinical utility of existing cut-offs and severity criteria by determining which are most strongly associated with risk for low bone mineral density (BMD). Height adjusted BMD Z scores were calculated for 352 females: 262 with AN and 90 healthy controls (controls) (12-20.5 years), using data from the BMD in Childhood Study, for the lumbar spine, whole body less head, and total hip. For most cut-offs used to define low weight (5th or 10th BMI percentile, BMI of 17.5 or 18.5, and 85 or 90% of median BMI), AN had lower BMD Z scores than controls. AN at >85 or >90% expected body weight for height (EBW-Ht) did not differ in BMD Z scores from controls, but differed significantly from AN at ≤85 or ≤90% EBW-Ht. Among AN, any amenorrhea was associated with lower BMD. AN had lower BMD than controls across DSM-5 and The Society for Adolescent Health and Medicine (SAHM) severity categories. The SAHM moderate severity classification was differentiated from the mildly malnourished classification by lower BMD at hip and spine sites. Amenorrhea and %EBW-Ht ≤ 85 or ≤ 90% are markers of severity of bone loss within AN. Among severity categories, BMI Z scores (SAHM) may have the greatest utility in assessing the degree of malnutrition in adolescent girls that corresponds to lower BMD.

ABSTRACT

Context: Areal bone mineral density (BMD) is lower, particularly at the spine, in low-weight women with anorexia nervosa (AN). However, little is known about vertebral integral volumetric BMD (Int.vBMD) or vertebral strength across the AN weight spectrum, including "atypical" AN [body mass index (BMI) ≥18.5 kg/m2]. Objective: To investigate Int.vBMD and vertebral strength, and their determinants, across the AN weight spectrum. Design: Cross-sectional observational study. Setting: Clinical research center. Participants: 153 women (age 18 to 45): 64 with low-weight AN (BMI <18.5 kg/m2; 58% amenorrheic), 44 with atypical AN (18.5≤BMI<23 kg/m2; 30% amenorrheic), 45 eumenorrheic controls (19.2≤BMI<25 kg/m2). Measures: Int.vBMD and cross-sectional area (CSA) by quantitative computed tomography of L4; estimated vertebral strength (derived from Int.vBMD and CSA). Results: Int.vBMD and estimated vertebral strength were lowest in low-weight AN, intermediate in atypical AN, and highest in controls. CSA did not differ between groups; thus, vertebral strength (calculated using Int.vBMD and CSA) was driven by Int.vBMD. In AN, Int.vBMD and vertebral strength were associated positively with current BMI and nadir lifetime BMI (independent of current BMI). Int.vBMD and vertebral strength were lower in AN with current amenorrhea and longer lifetime amenorrhea duration. Among amenorrheic AN, Int.vBMD and vertebral strength were associated positively with testosterone. Conclusions: Int.vBMD and estimated vertebral strength (driven by Int.vBMD) are impaired across the AN weight spectrum and are associated with low BMI and endocrine dysfunction, both current and previous. Women with atypical AN experience diminished vertebral strength, partially due to prior low-weight and/or amenorrhea. Lack of current low-weight or amenorrhea in atypical AN does not preclude compromise of vertebral strength.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

CONTEXT: Various fat depots have differential effects on bone. Visceral adipose tissue (VAT) is deleterious to bone, whereas subcutaneous adipose tissue (SAT) has positive effects. Also, marrow adipose tissue (MAT), a relatively newly recognized fat depot is inversely associated with bone mineral density (BMD). Bone mass in athletes depends on many factors including gonadal steroids and muscle mass. Exercise increases muscle mass and BMD, whereas, estrogen deficiency decreases BMD. Thus, the beneficial effects of weight-bearing exercise on areal and volumetric BMD (aBMD and vBMD) in regularly menstruating (eumenorrheic) athletes (EA) are attenuated in oligo-amenorrheic athletes (OA). Of note, data regarding VAT, SAT, MAT and regional muscle mass in OA compared with EA and non-athletes (C), and their impact on bone are lacking. METHODS: We used (i) MRI to assess VAT and SAT at the L4 vertebra level, and cross-sectional muscle area (CSA) of the mid-thigh, (ii) 1H-MRS to assess MAT at L4, the proximal femoral metaphysis and mid-diaphysis, (iii) DXA to assess spine and hip aBMD, and (iv) HRpQCT to assess vBMD at the distal radius (non-weight-bearing bone) and tibia (weight-bearing bone) in 41 young women (20 OA, 10 EA and 11 C 18-25 years). All athletes engaged in weight-bearing sports for ≥ 4 h/week or ran ≥ 20 miles/week. MAIN OUTCOME MEASURES: VAT, SAT and MAT at L4; CSA of the mid-thigh; MAT at the proximal femoral metaphysis and mid-diaphysis; aBMD, vBMD and bone microarchitecture. RESULTS: Groups had comparable age, menarchal age, BMI, VAT, VAT/SAT and spine BMD Z-scores. EA had higher femoral neck BMD Z-scores than OA and C. Fat mass was lowest in OA. SAT was lowest in OA (p = 0.048); L4 MAT was higher in OA than EA (p = 0.03). We found inverse associations of (i) VAT/SAT with spine BMD Z-scores (r = -0.42, p = 0.01), (ii) L4 MAT with spine and hip BMD Z-scores (r = -0.44, p = 0.01; r = -0.36, p = 0.02), and vBMD of the radius and tibia (r = -0.49, p = 0.002; r = -0.41, p = 0.01), and (iii) diaphyseal and metaphyseal MAT with vBMD of the radius (r ≤ -0.42, p ≤ 0.01) and tibia (r ≤ -0.34, p ≤ 0.04). In a multivariate model including VAT/SAT, L4 MAT and thigh CSA, spine and hip BMD Z-scores were predicted inversely by L4 MAT and positively by thigh CSA, and total and cortical radius and total tibial vBMD were predicted inversely by L4 MAT. VAT/SAT did not predict radius or tibia total vBMD in this model, but inversely predicted spine BMD Z-scores. When L4 MAT was replaced with diaphyseal or metaphyseal MAT in the model, diaphyseal and metaphyseal MAT did not predict aBMD Z-scores, but diaphyseal MAT inversely predicted total vBMD of the radius and tibia. These results did not change after adding percent body fat to the model. CONCLUSIONS: VAT/SAT is an inverse predictor of lumbar spine aBMD Z-scores, while L4 MAT is an independent inverse predictor of aBMD Z-scores at the spine and hip and vBMD measures at the distal tibia and radius in athletes and non-athletes. Diaphyseal MAT independently predicts vBMD measures of the distal tibia and radius.

ABSTRACT

Proximal focal femoral deficiency (PFFD) is a heterogeneous disorder characterized by various degrees of femoral deficiencies and associated anomalies of the pelvis and lower limbs. The etiology of the disease has not been determined. We report on a 3-year-old boy with severe PFFD, who showed almost completely absent femora and fibulae, malformed pelvis and ectrodactyly of the left foot. These features were partially overlapped with those of Al-Awadi-Raas-Rothschild syndrome or Fuhrmann syndrome, both of which are caused by WNT7A mutations. Molecular analysis of our case, however, demonstrated no disease-causing mutations in the WNT7A gene.

ABSTRACT

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.
