Introduction&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...

An Atypical Case of Mayer-Rokitansky-Kuster-Hauser Syndrome with Hyperandrogenemia

Ustyol Ala , Atabek Mehmet Emre

Background: Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is characterized by utero-vaginal atresia in patients with a normal female phenotype and 46, XX karyotype. Various anomalies may accompany MRKH. The number of cases with accompanying hyperandrogenemia is limited.Case presentation: We describe a combination of Mullerian agenesis and hyperandrogenemia (total testosterone level 0.85 ng/ml) in a patient presenting with primary amenorrhea and mild hir...

Co-occurrence of Turner (46,X-ring/45,X0 mosaicism) and Mayer-Rokitansky-Kuster-Hauser Syndromes: a case report

Ocello Laura , Ramponi Giulia , Maitz Silvia , Marco Santo Di , Adavastro Marta , Biondi Andrea , Cattoni Alessandro ,

Introduction: The co-occurrence of Turner Syndrome (TS) and Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) has been rarely described in literature. The resulting clinical picture includes congenital aplasia of the uterus and of the upper two-thirds of the vagina and ovarian dysgenesis.Case Report: We hereby report the case of a 14-year-old girl referred to our endocrine outpatient clinic for pubertal delay. Her previous medical history ...

Occurrence of central hypothyroidism in children with isolated growth hormone deficiency

Mayer Judith , Schweizer Roland , Binder Gerhard

Background: A small subgroup of children with isolated growth hormone deficiency (IGHD) develop central hypothyroidism (CH) during GH treatment. Prognostic parameters are still unclear.Objective and hypothesis: Long-term evaluation of children with initial diagnosis of IGHD to identify those with an unmasking CH under GH treatment. IGHD was diagnosed in children with short stature, low height velocity, retarded bone age,...

Nephrolithiasis and hypoparathyroidism with normocalcemia – detecting a new mutation solves the mystery

Reichardt Susen , Mayer Brigitte , Quitter Friederike , Huebner Angela

We report on a 17-year-old patient with hypoparathyroidism which was noticed during the diagnosis of a first renal colic a year and a half ago. At that time, a prevesical ureter stone on the right could be depicted sonographically, which disappeared spontaneously. Initially calcium levels in serum and urine were reported to be normal. However, a slight hypercalcemia and hypercalciuria as well as high normal vitamin D levels without vitamin D substitution were detected intermit...

Case Report: HAX1 Mutation/Kostmann Syndrome: A close cooperation between pediatric endocrinologists and hem-oncologists is crucial!

Mayer Isa , Calaminus Gabriele , Schreiner Felix , Nicole Saenger , Dilloo Dagmar , Gohlke Bettina

Purpose: Clinical problems caused by impaired molecular function of inborn errors of immunity (IEI) genes are not limited to the immunological system but can also affect the endocrine system. An autosomal recessive form of severe congenital neutropenia also known as Kostmann syndrome (KS) is caused by mutations in the gene encoding the mitochondrial protein HAX1. Knowing that most endocrine disorders associated with IEI are hypofunction, a close cooperation be...

Age differences in the distribution of diabetes-specific antibodies in children and adolescents with type 1 diabetes mellitus

Schweizer Roland , Mayer David , Bung Julia , Liebrich Franziska , Neu Andreas , Ziegler Julian

Background: The assignment to type 1 diabetes mellitus (T1DM) can be confirmed by the determination of diabetes-specific autoantibodies. Five different antibodies can be determined. The determination of several antibodies is more expensive than the determination of a single antibody. In times of scarce resources, the sequential determination of antibodies could save costs. The aim of this study was to determine the frequency of antibodies and their age and gen...

Diagnostic Spectrum of Female Pubertal Delay

Uday Suma , Alvi Sabah

Introduction: Delayed onset of puberty is quite a common presentation in adolescent endocrine clinics, and the most common cause, particularly in boys is considered to be constitutional delay of growth and maturation. In girls, however, it is more likely that there is a significant underlying problem.Objectives: To review the aetiology of pubertal delay in female patients referred to a single tertiary centre.Methods: All female pat...
