Background:
Delayed puberty can result either from constitutional delay of growth and puberty (CDP) or idiopathic hypogonadotropic hypogonadism (IHH). Gonadotropin-releasing hormone (GnRH) stimulation test has been generally accepted as a current method for diagnosing delayed puberty. The objective of this research was to assess the cut-off values and the efficacy of GnRH stimulation test in the diagnosis of delayed puberty in both males and females.Methods:
A study of 91 IHH, 27 CDP patients, 6 prepubertal children, and 20 pubertal adults was undertaken. Blood samples were obtained at 0, 30, 60, and 120 min after GnRH administration and the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured. For each parameter, the sensitivities and specificities were estimated, and the receiver operating characteristic (ROC) curves were constructed.Results:
The ROC curves indicated that a serum basal LH <0.6 IU/L or peak LH <9.74 IU/L resulted in moderate sensitivity (73.8% or 80.0%) and specificity (90.9% or 86.4%) in the diagnosis of HH in males. Serum basal LH <0.85 IU/L or basal FSH <2.43 IU/L resulted in moderate sensitivity (80.0% or 100.0%) and specificity (75.0% or 50.0%) in the diagnosis of HH in females.Conclusions:
Our data suggest that isolated use of the gonadorelin stimulation test is almost sufficient to discriminate between HH and CDP in males, but unnecessary in females. The most useful predictor is serum basal or peak LH to differentiate these two disorders in males, but serum basal LH or FSH in females. 相似文献2.

Background:
This study aimed to highlight the health seeking behavior of children in an Emergency Department (ED).Materials and Methods:
Retrospective files review of ED was done for the month of July, 2008. Data about the children ≤12 years of age was gathered.Results:
In one month period a total 21000 patients visited our ED, out of them 6120 (29%) were children. Males, Saudis and children of (1-6 years) were more frequent, i.e., 3540 (57.8%), 5760 (94.1%) and 3180 (52%), respectively. Majority of patients visited in shift “2”, i.e., 15:30 hours to 23:30 hours. Among the patients “diseases of respiratory system” were found more frequent 4170 (68.1%) and main diagnosis was “acute upper respiratory tract infection” 3300 (53.9%). Non-urgent cases were 2020 (33%) while 244 (4%) were admitted.Conclusion:
Young children as well as non-urgent cases were predominant. Evening shift was the busiest one. 相似文献11.
INTRODUCTION
The pandemic caused by the H1N1 influenza virus in 2009 resulted in extensive morbidity and mortality worldwide. As the virus was a novel virus, there was limited data available on the clinical effects of the virus on children in Malaysia. We herein describe the clinical characteristics of children hospitalised with H1N1 influenza at a tertiary care centre. We also attempted to identify the risk factors associated with disease severity.METHODS
In this retrospective study, we compared the characteristics of the children who were admitted to the University of Malaya Medical Centre, Malaysia, for H1N1 influenza during the pandemic with those who were admitted for seasonal influenza in 2002–2007.RESULTS
Among the 77 children (aged ≤ 12 years) admitted to the centre due to H1N1 influenza from 1 July 2009–30 June 2010, nearly 60.0% were aged < 6 years and 40.3% had an underlying medical condition. The top three underlying medical conditions were bronchial asthma (14.3%), cardiac disease (10.4%) and neurological disorders (11.7%). The risk factors for severe disease were age ≤ 2 years, underlying bronchial asthma and chronic lung disease. Two of the three patients who died had an underlying medical condition. The underlying causes of the deaths were acute respiratory distress syndrome and brain stem encephalitis.CONCLUSION
The clinical presentation of the children infected with pandemic (H1N1) 2009 influenza virus did not differ significantly from that of children with seasonal influenza. However, there were more complaints of fever, cough and vomiting in the former group. 相似文献12.

Background
Despite her apparent economic success, India is plagued by a high burden of under-nutrition among children under five. This study was aimed at understanding some of the risk factors for under-nutrition in a region with favourable maternal and child health indicators.Method
A case control study was carried out among children aged one to five years attending the paediatric outpatient department in six rural health care centres in Udupi taluk of Karnataka in Southern India. A total of 162 children were included in the study, of which 56 were cases. A semi-structured questionnaire was used to interview the caregivers of the children and the nutritional status was graded according to the Indian Academy of Paediatrics (IAP) grading of protein-energy malnutrition.Results
Under-nutrition was associated with illness in the last one month [OR– 4.78 (CI: 1.83 –12.45)], feeding diluted milk [OR–14.26 (CI: 4.65 – 43.68)] and having more than two children with a birth interval ≤2 years [OR– 4.93 (CI: 1.78 – 13.61)]. Lack of exclusive breast feeding, level of education of the caregiver and environmental factors like source of water did not have an association.Conclusion
Childhood illness, short birth interval and consumption of diluted milk were some of the significant contributory factors noted among this population. Information, Education, Communication (IEC) campaigns alleviating food fads and promoting birth spacing is needed. 相似文献13.

Background:
At present, China has listed the compound tablet containing a fixed dose of rosiglitazone and metformin, Avandamet, which may improve patient compliance. The aim of this study was to evaluate the efficacy and safety of Avandamet or uptitrated metformin treatment in patients with type 2 diabetes inadequately controlled with metformin alone.Methods:
This study was a 48-week, multicenter, randomized, open-labeled, active-controlled trial. Patients with inadequate glycaemic control (glycated hemoglobin [HbA1c] 7.5–9.5%) receiving a stable dose of metformin (≥1500 mg) were recruited from 21 centers in China (from 19 November, 2009 to 15 March, 2011). The primary objective was to compare the proportion of patients who reached the target of HbA1c ≤7% between Avandamet and metformin treatment.Results:
At week 48, 83.33% of patients reached the target of HbA1c ≤7% in Avandamet treatment and 70.00% in uptitrated metformin treatment, with significantly difference between groups. The target of HbA1c ≤6.5% was reached in 66.03% of patients in Avandamet treatment and 46.88% in uptitrated metformin treatment. The target of fasting plasma glucose (FPG) ≤6.1 mmol/L was reached in 26.97% of patients in Avandamet treatment and 19.33% in uptitrated metformin treatment. The target of FPG ≤7.0 mmol/L was reached in 63.16% of patients in Avandamet treatment and 43.33% in uptitrated metformin treatment. Fasting insulin decreased 3.24 ± 0.98 μU/ml from baseline in Avandamet treatment and 0.72 ± 1.10 μU/ml in uptitrated metformin treatment. Overall adverse event (AE) rates and serious AE rates were similar between groups. Hypoglycaemia occurred rarely in both groups.Conclusions:
Compared with uptitrated metformin, Avandamet treatment provided significant improvements in key parameters of glycemic control and was generally well tolerated. Registration number: ChiCTR-TRC-13003776. 相似文献14.

INTRODUCTION
Intrauterine insemination (IUI) after controlled ovarian hyperstimulation (COH) was applied to selected infertile patients to determine the effect of gonadotropin-releasing hormone (GnRH) antagonists in IUI cycles, in which recombinant follicle-stimulating hormone (rFSH) had been used for COH.METHODS
This study was conducted between April 1, 2009 and June 10, 2009, and involved a total of 108 patients. These patients had primary or secondary infertility, which resulted in an indication for IUI, and they each received two cycles of ovarian stimulation treatment with clomiphene citrate. The patients were randomised into two groups – patients in group A received rFSH + GnRH antagonist (n = 45), while those in group B received only rFSH (n = 63).RESULTS
The mean age of the patients was 31.84 ± 3.73 years and the mean body mass index (BMI) was 24.40 ± 1.88 kg/m2. The mean age and BMI of the patients in groups A and B were not significantly different. There was no significant difference in the mean total rFSH dose administered (988.33 IU in group A and 871.83 IU in group B). When compared to group B, the mean number of follicles that were > 16 mm on the human chorionic gonadotropin (HCG) trigger day was significantly higher in group A (1.58 and 1.86, respectively; p < 0.05). When the two groups were compared, there were no statistically significant differences in the number of cancelled cycles due to premature luteinisation (none in group A vs. two in group B) and the rate of clinical pregnancy (8.9% in group A vs. 7.9% in group B).CONCLUSION
No significant improvement in the clinical pregnancy rates was observed when GnRH antagonists were used in COH + IUI cycles, despite the significant increase in the number of follicles that were > 16 mm on HCG trigger day. 相似文献15.
特发性中枢性性早熟女童GnRHa治疗前后心理行为的变化 总被引:3,自引:0,他引:3
目的:了解特发性中枢性性早熟(ICPP)女童心理行为改变与血清脱氢表雄酮(DHEA)、硫酸脱氢表雄酮(DHEAS)的关系,探讨长效促性腺激素类似物(GnRHa)在逆转或阻断ICPP女童不良心理行为中的作用。方法:由专人采用瑞文标准推理测验、艾氏儿童行为量表、自尊量表(SES)、躯体自信量表(BES)等对确诊ICPP女童和对照组女童进行心理行为的评估,用ELISA法检测DHEA、DHEAS水平,并对GnRHa治疗的ICPP女童进行DHEA、DHEAS及心理行为的随访。结果:①ICPP女童SES、BES的评分明显低于对照组(P〈0.05);而艾氏儿童行为量表的抑郁、退缩、攻击性、体诉这4个因子的评分,ICPP组女童明显高于对照组(P〈0.05);②ICPP组女童经GnRHa治疗12个月后,SES、BES得分有改善,治疗前、后比较差异有显著意义(P〈0.05)。ICPP组女童GnRHa治疗前血清DHEA为Log(0.77+0.36)μg/L,明显高于对照组Log(0.28±0.22)μg/L(P〈0.01);GnRHa治疗后3个月,DHEA和DHEAS浓度明显下降;而治疗12个月时,DHEA和DHEAS与治疗前比较差异无显著意义(P〉0.05)。③ICPP女童SES的分值和BES中的体重关注、身体耐力2个分值与DHEA呈负相关(r分别为-0.492、-0.356、-0.202和-0.216,P均〈0.05);而艾氏儿童行为量表的9个因子与DHEA无相关关系。结论:ICPP女童存在自尊程度低,自信心不足,且这种自尊程度和自信心不足随体内DHEA水平的增高而更加明显;性早熟女童更容易表现为抑郁、退缩、攻击性和好抱怨,但与体内DHEA水平变化无关;GnRHa治疗能不同程度地逆转ICPP女童的自尊程度低和自信心不足。 相似文献

Background:
Tuberculum sellae meningiomas (TSMs) present a special symptom because of the adherence and compression to the optic nerve, optic artery, and the chiasm. A significant number of patients with TSMs appear visual deficits. This study aimed to investigate the surgical indications of exploring the optic canal and visual prognostic factors in the neurosurgical treatment of TSMs.Methods:
Totally 21 patients with TSM, who were operated from September 2007 to August 2011 in the Department of Neurosurgery, Tongren Hospital were enrolled in this study. Results of orbital computed tomography (CT) and magnetic resonance imaging (MRI), visual acuity, Goldmann visual field test, orbital color Doppler flow imaging (CDI) test in these patients were retrospectively analyzed.Results:
Visual deficit and optic canal involvement (OCI) were detected in all the 21 patients. Fourteen patients had bone proliferation within the area of the optic canal. After the operation, visual outcomes were improved in 13 patients, unchanged in 7 patients, and deteriorated in 1 patient. All the 21 patients performed orbital CDI test preoperatively, the results showed that if the peak systolic velocity (PSV) of central retinal artery (CRA) value was ≤8 cm/s, the visual outcome would be better.Conclusions:
The surgical indications of exploring optic canal in TSM cases included: (1) The neuroimaging evidences of OCI (CT and/or MRI); (2) PSV of CRA in orbital CDI test was ≤8 cm/s; (3) visual acuity was below 0.1; (4) visual field deficit. The PSV of CRA in CDI test could be a prognostic factor for visual outcomes of TSMs. 相似文献17.

Background:
As a Chinese Traditional Medicine product, Kuntai capsule could improve the peri-menopausal symptoms in postmenopausal women. But it is still not clear whether Kuntai capsule has a good effect on alleviating peri-menopausal symptoms induced by gonadotropin releasing hormone agonist (GnRH-a) treatment. The purpose of this study was to investigate the clinical effectiveness and safety of Kuntai capsule, on peri-menopausal symptoms in endometriosis (EMS) patients, with postoperative GnRH-a treatment.Methods:
Ninety EMS ovarian cyst women with postoperative GnRH-a administration were enrolled in the study, and were randomly divided into Kuntai group, Tibolone group, or blank Control group. The therapeutic strategy in Kuntai group was 4 Kuntai capsules tid,po for 12 weeks after the first GnRH-a injection, while Tibolone 2.5 mg qd, po for 12 weeks in Tibolone group. There was no drug addition in Control group. Climacteric complaints were evaluated by Kupperman menopausal index (KMI) and hot flash/sweating score. Liver and renal functions, lipid profile, serum sex hormone levels and endometrial thickness were measured, and the frequency of adverse events in Kuntai and Tibolone groups was recorded.Results:
(1) Before GnRH-a therapy, the baseline parameter results were comparable in the three groups (P > 0.05). (2) After GnRH-a therapy, KMI and hot flash/sweating scores in all the three groups increased significantly (P < 0.05). At the 4th week after GnRH-a therapy, KMI and hot flash/sweating score results were as follows: Control group > Kuntai group > Tibolone group (P < 0.05); at the 8th and 12th week after GnRH-a therapy, KMI and hot flash/sweating score in Control group were significantly higher than the other two groups (P < 0.05), and no significant difference was identified between Kuntai and Tibolone group (P > 0.05). (3) No statistical change took place in the liver and renal functions and lipid profile in all the three groups after the treatment (P > 0.05). (4) The posttherapeutic serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) level and endometrial thickness decreased significantly in all the three groups (P < 0.05). After therapy, serum E2 level in Tibolone group was obviously higher than the other two groups (P < 0.05), while FSH and LH levels were obviously lower (P < 0.05). (5) The incidence of vaginal bleeding, breast distending pain in Tibolne group was obviously higher than Kuntai group (P < 0. 05).Conclusions:
Kuntai capsule is effective on the peri-menopausal symptoms induced by postoperative GnRH-a administration to EMS patients, although its clinical effect might be a few weeks later than Tibolone. Kuntai capsule might be a little safer than Tibolone tablet. 相似文献18.

Background:
Iron deficiency anaemia is the most common nutritional anaemia among children. Lead toxicity is a serious health threat, especially in developing countries due to environmental pollution. It was thus aimed to investigate correlation between blood lead concentration and iron deficiency in children of Mashhad, Iran.Materials and Methods:
This cross sectional study was performed on children between 1 year and 10 years, in Imam Reza teaching hospital of Mashhad, Iran, in 2010. Indeed during complete blood count (CBC), we measured iron and total iron binding capacity (TIBC) by colorimetric methods, ferritin by radioimmune assay and blood lead concentration by atomic absorption method. Results were analysed by Statistical Package for Social Sciences (SPSS) (version 11.5), using statistical tests including independent sample t-test, Mann-Whitney U test, Spearman''s test and analysis of variance (ANOVA) and Pearson''s or Spearman''s correlation coefficient. P value ≤ 0.05 was considered as a significant level.Results:
We studied 223 cases including 98 control children and 125 patients. All children had lead intoxication. Mean (±SD) blood lead concentration in the control group was 57.1 ± 25.3 (ranged 20-212) μg/dl and in the patient group was 57 ± 20.4 (ranged 10.9-159) μg/dl with no significant difference (P value = 0.713). We also did not find any correlation between blood lead concentration and haemoglobin, ferritin, iron, TIBC, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cells (WBC) and platelets.Conclusion:
Based on these results, no correlation was found between blood lead concentration and iron deficiency in the children. Because all children had lead intoxication, further studies in highly polluted and a comparison with a low polluted area are necessary to make a general conclusion. 相似文献19.
Background:
Following the high rate of consumption of Cola nitida (cola nut) among the male population in Nigeria, this study seeks to determine the effects of consumption of Cola nitida on serum reproductive hormones and sperm count, which are major determinants of male fertility.Materials and Methods:
Thirty-two male albino wistar rats weighing 180-220 g were used for this study and were divided into 4 groups of eight animals each. Group 1 served as control, group 2 received 2 mg/kg Cola nitida extract (Test 1), group 3 received 6 mg/kg Cola nitida extract (Test 2) and group 4 received 10 mg/kg Cola nitida extract (Test 3). After 6 weeks of treatment, reproductive hormonal assay was carried out using the rat serum. Epididymal spermatozoa were collected and sperm count determined.Results:
Serum concentrations of luteinizing hormone (LH) and testosterone were significantly (P < 0.05) reduced in test 2 and 3, compared with control. Sperm count was significantly lower in test group 1 (P < 0.05), 2 (P < 0.001) and 3 (P < 0.001) compared with control, with test 3 significantly (P < 0.05) lower compared with test 1. There was no significant difference in testicular and epididymis weight in the different experimental groups studied.Conclusion:
Aqueous seed extract of Cola nitida rubra resulted in reduced serum reproductive hormone concentrations and sperm count in male wistar rats, and may therefore be detrimental to reproductive health, hence the need for regulation of its consumption. 相似文献20.
