A SHOX géndeletio előfordulása idiopathiás alacsonynövésben

INTRODUCTION: The isolated haploinsufficiency of the SHOX gene is one of the most common cause of short stature determined by monogenic mutations. The heterozygous deviation of the gene can be detected in 2-15% of patients with idiopathic short stature (ISS), in 50-90% of patients with Leri-Weill dyschondrosteosis syndrome (LWS), and in almost 100% of patients with Turner syndrome. AIM: The aim of our study was to evaluate the frequency of SHOX gene haploinsufficiency in children with ISS, LWS and in patients having Turner syndrome phenotype (TF), but normal karyotype, and to identify the dysmorphic signs characteristic for SHOX gene deficiency. METHOD: A total of 144 patients were included in the study. Multiplex Ligation-dependent Probe Amplification (MLPA) method was used to identify the SHOX gene haploinsufficiency. The relationships between clinical data (axiological parameters, skeletal disorders, dysmorphic signs) and genotype were analyzed by statistical methods. RESULTS: 11 (7.6%) of the 144 patients showed SHOX gene deficiency with female dominance (8/11, 81% female). The SHOX positive patients had a significantly higher BMI (in 5/11 vs. 20/133 cases, p<0.02) and presented more frequent dysmorphic signs (9/11vs 62/133, p = 0.02). Madelung deformity of the upper limbs was also significantly more frequent among the SHOX positive patients (4/11, i.e. 36%, vs. 14/133, i.e. 10%, p = 0.0066). There were no statistically significant differences between the mean age, mean height and auxological measurements (sitting height/height, arm span/height) between the two groups of patients. CONCLUSIONS: The occurrence of SHOX gene haploinsufficiency observed in our population corresponds to the literature data. In SHOX positive patients, in addition to short stature, the dysmorphic signs have a positive predictive value for SHOX gene alterations. However, the SHOX deletion detected in a patient with idiopathic short stature without dysmorphic signs suggest that SHOX deletion analysis can be recommended in patients with ISS.

Changes of urinary iodine excretion of newborns over a period of twenty years.

The use of iodized salt is not mandatory in Hungary and supply is irregular since decades. The effect of this anomaly was studied on the neonatal urinary iodine excretion over a period of twenty years.Journal Articleinfo:eu-repo/semantics/publishe

Growth hormone and treatment outcomes: expert review of current clinical practice

Although there are guidelines for treatment of short stature, open questions regarding optimal management of growth hormone therapy still exist. Experts attending six international meetings agree that successful therapy results in the patient attaining mid-parental height, and relies on correct diagnosis and early intervention. Experts advocate patient followup every 3-6 months, and that growth and adherence should be monitored at each visit. Growth response is variable, and an accepted definition of good/poor response is lacking. Combined with patient education and regular patient follow-up, a definition of treatment response could lead to improved treatment outcomes. Few experts use prediction models in clinical practice, but all agree that pharmacogenetics might improve prediction, enable early therapy modulation, and promote growth. Poor growth is often due to low adherence. Guidance on optimal management of growth hormone therapy is required, with focus on early diagnosis, dosing, treatment monitoring, adherence, and motivation

Relationships between urethrovesical angles and urinary incontinence due to urethral sphincter mechanism incompetence in bitches

In women, the posterior urethrovesical angle is thought to be an important factor in the aetiology of stress urinary incontinence. This form of incontinence has many similarities to urethral sphincter mechanism incompetence (SMI) in the bitch. The role of the ventral and dorsal urethrovesical angles in the aetiology of SMI in the incontinent bitch has yet to be established. Positive-contrast retrograde vagino-urethrograms from 30 incontinent bitches with a diagnosis of SMI and 30 continent bitches were retrieved and the angles between the urethra and dorsal and ventral bladder walls were measured. No relationship was shown to exist between the dorsal urethrovesical angle (the equivalent of the posterior urethrovesical angle in women) and urinary incontinence due to SMI in bitches. Differences in ventral urethrovesical angles were considered to be associated with differences in bladder neck position between the two groups of bitches
