Determination of iodine concentration in urine by isotope dilution analysis and thyroid volume of school children in the west coast of Turkey after mandatory salt iodization

OBJECTIVE: This study was designed to evaluate iodine deficiency status in children 6-12 years in the west coast (Aegean Region) of Turkey after 5 years of mandatory iodine prophylaxis. A total of 2300 children from 72 populations (rural and urban area) were evaluated with urinary iodine excretion and thyroid volume. DESIGN: Cross-sectional, observational study designed and performed according to surveillance methods for iodine deficiency disease (IDD) prevalence recommended by WHO/UNICEF/ICCIDD. SUBJECTS: The study population consisted of 2300 school children age ranging from 6 to 12 years. The children were selected by multiple stage randomization from 91 primary schools of 76 zones (91 clusters). Information about the use of iodized salt was obtained from the families. MEASUREMENTS: Data on the following were collected: birth date, sex, weight, height, thyroid size by palpation and ultrasonography; and urinary iodine by isotope dilution analysis method. Thyroid volumes above 97th percentile according to the WHO/ICCIDD by age and body surface area (BSA) were accepted as goitre. RESULTS: Iodized salt consumption was 51.7%. The prevalence of goitre determined by palpation was 12.1% and by ultrasound based on BSA and age were 9.8% and 5.5%, respectively. Median urinary iodine was 53 (2-142) microg/l. CONCLUSION: Mild to severe degree of iodine deficiency was detected in the west coast of Turkey.     

The importance of caregivers in the outcome of pediatric HIV management,Mombasa, Kenya

We assessed programmatic gaps that prevent the optimal treatment of pediatric HIV infection despite free antiretroviral care in Kenya. Of 626 HIV-infected Kenyan children, the median age was five years, 54% were male and the mortality rate was 3.2 per 100 person-years. A total of 380 (61%) children initiated antiretroviral therapy (ART) during the study period. Among the 246 children who never started ART, 129 (52%) met the criteria for ART initiation. Immunologic failure occurred in 20% of children who received ART for >24 weeks. In multivariate analysis, immunological failure was associated with having nonimmediate relative or unrelated caregivers accompanying the child to clinic (AOR = 69.16, p = 0.008). Having ≥3 types of accompanying caregivers was also associated with virologic failure in multivariate analysis (AOR = 3.84, p = 0.03). The lost to follow-up rate was 8.7/100 persons-years for the entire cohort, and significantly higher (17.7/100 persons-years) among children not on ART (p < 0.001). Among children who do initiate ART, those with the best treatment outcomes were those who had a limited number of close relatives as caregivers and good adherence to ART. Focus on early ART initiation and education of the right caregiver will likely improve retention and quality of pediatric HIV care in Kenya.     

Serum galectin-3 level in systemic sclerosis

Systemic sclerosis (SSc) is an autoimmune disease of unknown etiology characterized by progressive fibrosis. Activated fibroblasts are mainly responsible for fibrosis in SSc. Galectin-3, a β-galactoside-binding lectin, plays many important regulatory roles in both physiological and pathological processes including proliferation, apoptosis, inflammation, and fibrosis. The purpose of this study was to assess the serum galectin-3 levels in patients with SSc. Thirty-seven SSc patients, 23 systemic lupus erythematosus (SLE) patients (serving as patient control group), and 28 healthy volunteers were enrolled in this study. Disease activity and severity scores were detected with Valentini disease activity index and Medsger disease severity scale in the SSc group and SLE disease activity index and Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index in the SLE group. The serum levels of galectin-3, vascular endothelial growth factor, transforming growth factor-β, and interleukin-6 were determined. Compared to the control group, the galectin-3 levels were higher in the SSc and SLE groups. The galectin-3 levels were not correlated with the disease activity and severity indexes in both patient groups. But, the serum galectin-3 levels were higher in the active SSc and SLE subgroups than in the inactive SSc (4.6?±?5.8 vs. 1.3?±?1.1 ng/ml, p?=?0.015) and SLE (17.4?±?11.3 vs. 6.5?±?8.9 ng/ml, p?=?0.019) subgroups. These results suggest that galectin-3, which is associated with fibrosis and inflammation by previous studies, may be a prominent biomarker of disease activity in SSc.

The effect of preoperative anxiety on postoperative analgesia and anesthesia recovery in patients undergoing laparascopic cholecystectomy

Purpose

In patients who are hospitalized for surgery, anxiety disorders are frequently observed. Anxiety affects the patient’s perception of postoperative pain and has a negative impact on recovery from anesthesia. This study attempted to compare the effect of preoperative anxiety on postoperative pain control and recovery from anesthesia in patients undergoing laparoscopic cholecystectomy.

Methods

A total of 80 patients were enrolled who were undergoing laparoscopic cholecystectomy. Demographic characteristics of the patients were recorded. Beck’s anxiety ?nventory (BAI) was administered to the patients: patients with anxiety were included in the high-anxious patient group (group H) and patients without anxiety were enrolled in the low-anxious group (group L). Duration of surgery, duration of anesthesia, extubation time, and adverse effects were recorded. During the postoperative period, patient-controlled analgesia with tramadol was used for pain control. Visual analog scale (VAS) scores and tramadol consumption of all patients were recorded.

Results

Among all patients, 31 (38.75 %) patients had preoperative anxiety, and significant correlation was found between the days of hospitalization and preoperative score of BAI. In group L, extubation time, the time for the modified Aldrete score to reach 9, was seen as significantly shorter and fewer postoperative side effects were determined. Also in group L, postoperative VAS score and tramadol consumption were significantly lower, and less tenoxicam was needed.

Conclusion

A high preoperative anxiety level negatively affects recovery from anesthesia and control of postoperative pain. In this patient group, the increased need for postoperative analgesia must be adequately met.
