Abnormal uterine bleeding (AUB) is adolescent girls' most common gynecologic complaint. This study aimed to determine the diagnostic and management differences between those with/without heavy menstrual bleeding. We collected retrospective data such as follow-up, final control, and treatment regimen of adolescents aged 10-19 with the diagnosis of AUB. We excluded adolescents with known bleeding disorders at admission. We classified all subjects according to the level of anemia. Group 1 consisted of subjects with heavy bleeding (Hb10 g/dl) presented in Group 2. Admission and follow-up characteristics between the two groups were compared. In this study, we included 79 adolescent girls with a mean age was 14.3±1.8 years. 85% of all had a menstrual irregularity in the first two years after menarche. Anovulation was observed in 80%. 95% of group 1 had irregular bleeding in the two years (p<0.01). In all subjects, while 13 girls (16%) were diagnosed with PCOS, two adolescents (2%) had structural anomalies. No adolescents had hypothyroidism or hyperprolactinemia. Three (10.7%) were diagnosed with Factor 7 deficiency. Nineteen girls had MTHFR mutation. None had venous thromboembolism during at least six month-follow-up-period. This study showed that 85% of AUB had occurred in the first two years. We found the frequency of hematological disease (Factor 7 deficiency) 10.7%. The frequency of MTHFR mutation was 50%. We thought this did not increase the risk of bleeding/thrombosis. Its routine evaluation was not necessarily due to the similarity in population frequency.

Craniopharyngiomas (CPG) have complex challenges in treatment due to their proximity to vital structures, surgical and radiotherapeutic complexities, and the tendency for recurrence. This study aims to identify the prevalence of endocrine and metabolic comorbidities observed during initial diagnosis and long-term follow-up in a nationwide cohort of pediatric CPG patients. The study also highlights the associated difficulties in their management. Sixteen centers entered 152 patients into the ÇEDD NET data system. We evaluated the clinical and laboratory characteristics at presentation, administered treatments, accompanying endocrine, metabolic, and other system involvements, and the patient's follow-up features. Of the evaluated patients, 64 were female, and 88 were male. At presentation, the mean age was 9.1 ± 3.67 (min:1.46-max:16.92) years. The most common complaints at presentation were headache (68.4%), vision problems (42%), short stature (15%), nausea and vomiting (7%). The surgical procedure applied to the patients was gross total resection (GTR) in 97 cases (63.8%) and subtotal resection in 55 cases (36.2%). Radiotherapy was initiated in 11.8% of the patients. In the pathological examination, 92% of the cases were adamantinamatous type, 8% were papillary type. Postoperatively, hormone deficiencies consisted of thyroid-stimulating hormone (92.1%), adrenocorticotropic hormone (81%), antidiuretic hormone (79%), growth hormone (65.1%), and gonadotropin (43.4%) deficiencies. Recombinant growth hormone treatment (rhGH) was initiated on 27 patients. The study showed hesitancy among physicians regarding rhGH. The median survival without relapse was 2.2 years. Median time of relapse was 1.82 years (range: 0.13-10.35 years). Relapse was related to longer follow-ups and reduced GTR rates. The median follow-up time was 3.13 years. Among the last follow-up visits, the prevalence of obesity was 38%, but of these, 46.5% were already obese at diagnosis. However, 20% who were not obese at baseline became obese on follow-up. Permanent visual impairment was observed in 26 patients, neurological deficits in 13 patients, and diabetes mellitus in 5 patients. Recurrence was predominantly due to incomplete resection and the low rate of postoperative radiotherapy. It also emphasized challenges in multidisciplinary regular follow ups and suggested early interventions such as dietary restrictions and increased exercise to prevent obesity.

Cardiac involvement is common in Noonan syndrome (NS). Concerns have been raised regarding the effect of recombinant growth hormone (rGH) use on ventricular wall thickness and a possible increased risk of cardiac side effects. This study aimed to investigate the effect of rGH on the development of hypertrophic cardiomyopathy and other cardiac findings in NS Patients under the age of 18 years and diagnosed with NS according to the Van der Burgt criteria, were included. Patients were divided into two groups according to those receiving rGH or not at the time of obtaining cardiac measurements. Before and after the treatment, electrocardiographic and echocardiographic (ECHO) assessments were made, including interventricular septal thickness, left ventricular internal diameter, and left ventricular posterior thickness. Results were expressed as Z scores. Twenty-four NS subjects (16 boys, eight girls) were included. At the beginning of the follow up, the overall height standard deviation score was -2.56±0.94. Sixteen were on rGH. The mean rGH treatment duration was 8.3±3.8 years, and the mean dose was 0.22±0.04 mg/kg/week. The final height was 169±8.2 cm, and 10 of 11 patients who reached the final height received rGH. There was no difference between the rGH and non-rGH groups in terms of ECHO parameters pre-and post-treatment. In this cohort, there was no change in ECHO parameters on rGH and during follow-up. These results suggest that rGH is safe in NS patients with cardiac pathology under close follow-up.

MIRAGE syndrome is a rare multisystemic disorder characterized by various manifestations, such as myelodysplasia, susceptibility to infections, growth retardation, adrenal hypoplasia, genital anomalies, and enteropathy. In the literature, there have been rare cases of dysautonomia. We present a 6.5-year-old girl, who was first admitted to our department with short stature. On follow up, she exhibited multiple endocrinological issues, including transient hypothyroidism, primary hypoparathyroidism and dysautonomia, along with multisystem involvement. Further investigations revealed recurrent moniliasis, low IgM levels, and transient monosomy 7 in the bone marrow. Whole exome sequencing revealed a heterozygous pathogenic variant of SAMD9 (c.2159del; p.Asn720ThrfsTer35). Additional complications observed during follow-up included medullary nephrocalcinosis, hypomagnesemia, hypermagnesiuria, hypophosphatemia, decreased glomerular filtration rate, and nephrotic proteinuria. The patient also developed hyperglycemia, which was managed with low-dose insulin. This case highlights the diagnostic challenges and the diverse phenotypic presentation observed in MIRAGE syndrome.

Objective: In patients with classical congenital adrenal hyperplasia (CAH), virilization affects the brain and external genitalia due to antenatal androgen exposure. There are few studies on how the effects of androgens on brain virilization are reflected in behavior. However, there is no study focused on the adolescence period. The aim of this study was to evaluate the level of aggression in adolescent girls with classical CAH (due to 21 hydroxylase and 11β hydroxylase deficiency) and to investigate the disease‐related factors that may affect aggression.Design: Twenty female and 20 male patients aged 13–20 years, diagnosed with classical CAH, with 21 hydroxylase deficiency and 11β hydroxylase deficiency, and 20 healthy girls and 20 boys from the same age group were included. The Buss‐Perry Aggression Scale (BPAS), which consists of four subgroups measuring physical aggression, verbal aggression, hostility, and angry behaviors, was used.Results: The ages of the male and female patients with CAH were 16.30 ± 2.65 and 16.60 ± 2.41 years, respectively. Total aggression scale scores were 73.3 ± 14.6 in adolescent girls with CAH, 74.1 ± 11.2 in healthy girls, 71.5 ± 14.8 in boys with CAH, and 75.3 ± 14.5 in healthy boys (p > .05). There was no difference between the subscale scores of patients and healthy adolescents. Aggression scores in adolescents with CAH increased significantly with age.Conclusions: In this study, we found no difference between the aggression scores of adolescents with classical CAH compared to their healthy peers. The total aggression score and subscale were similar in unaffected female adolescents.
