Comparison of two different GnRH analogs' impact on final height in girls with early puberty: Triptorelin acetate vs. leuprolide acetate.

CONTEXT: GnRHa treatment has been a standard of care in progressive early puberty (EP). Choice of the GnRHa formulation is dependent on the preference of the clinician. OBJECTIVE: To compare the effects of triptorelin acetate (TA) and leuprolide acetate (LA) on anthropometry in girls with EP. DESIGN: A descriptive observational study. SUBJECTS AND METHODS: Girls diagnosed with central EP and treated with GnRHa at least for one year were included; treated with TA (n=46) and LA (n=35). First year anthropometric response and final height were evaluated. RESULTS: The mean age at the initiation of GnRHa treatment of girls was 8.5±0.5 years. The ratio of obesity and of overweight was 7.4 and 25.9%, respectively. In both TA and LA groups, anthropometric data of the patients at initiation and at the first year of treatment were similar. Although growth velocity was similar in each group, in LA group height SDS at the first year of the treatment showed a significant decrease (p=0.045), but not in TA group (p=0.317). No significant ΔBMI was observed with treatment. The differences between FH - PAH at initiation (height gain) in TA and LA groups were 2.9±4.7 and 4.0±5.8 cm, respectively (p=.316). Height gain per treatment year was 1.7±3.0 cm. CONCLUSIONS: There was a significant decrease in height SDS at the first year of leuprolid treatment, but not in triptorelin. Although these two analogs show similar effects on treatment, a not significant but slightly better benefit in leuprolide was observed.

Risk factors for mortality caused by hypothalamic obesity in children with hypothalamic tumours.

BACKGROUND: Hypothalamic obesity (HyOb) is a common complication of childhood hypothalamic tumours. Patients with HyOb probably have a higher mortality rate than those with other types of obesity due in many cases to obstructive sleep apnoea/hypoventilation. OBJECTIVES: To identify predictive factors for mortality caused by HyOb in children. METHODS: Twenty children with HyOb secondary to hypothalamic tumours that were followed-up for ≥3 years and aged <15 years at diagnosis, and received supraphysiological glucocorticoid treatment for ≤1 month. RESULTS: Mean age at diagnosis was 6.36 ± 3.60 years. Mean body mass index (BMI) Standard deviation of the samples (SDS) increased from 0.77 ± 1.26 to 2.66 ± 1.45 during the first 6 months, but slowed from month 6-12 (2.73 ± 1.35). ΔBMI SDS at 0-6 months was significantly higher in patients aged <6 years at diagnosis than in those aged >6 years at diagnosis (3.71 ± 1.96 vs. 0.83 ± 0.73, P < 0.001). Maximum BMI SDS was also significantly higher in the younger group (3.88 ± 1.39 vs. 2.79 ± 0.64, P < 0.05). In all, four patients died and the mortality rate was significantly higher in the patients with a further increase in BMI SDS > 1 SDS after 6 months of therapy (RR: 8.4, P < 0.05). Both overall mortality and obesity-related mortality rates were higher in the patients aged <6 years at diagnosis (4.5-fold, 7.2-fold higher, respectively, P > 0.05). The mortality rate was also 3.7-fold higher in the patients with a maximum BMI SDS ≥ 3 at any time during the first 3 years after therapy(P > 0.05). CONCLUSIONS: An increase in BMI SDS after 6 months of therapy was observed to be a risk factor for mortality caused by HyOb. In addition, age <6 years at diagnosis and a maximum BMI SDS ≥ 3 were associated with a higher mortality rate, indicating that earlier and more aggressive treatment of obesity is required.

Assessment of HIV/AIDS awareness and changes in sexual practices among secondary school students in Nsukka environment.

This study is aimed at assessing the awareness of HIV/AIDS and changes in sexual behaviour among the Nigerian teens. Two hundred and fifty secondary school students were interviewed. Only 5% of the respondents were able to state the full meaning of HIV or AIDS. A minority (28%) believed that HIV was real while the majority (72%) believed that HIV infects whites only. Forty-eight percent of them have changed their sexual practices owing to the AIDS menace. A small percentage, 12%, believed that HIV/AIDS could kill. The study revealed low awareness of HIV/AIDS as well as misconception about the infection, especially in non-urbanized cities of Nigeria.
