Abstract
OBJECTIVE Although there is a relationship between earlier onset of puberty and increased adiposity tissue. Publications in the literature on adiposis in patients with central precocious puberty (CPP) and visceral fat thickness (VFT) have conflicting results. So, in this study, we aimed to evaluate the relationship between sexual maturation and obesity in the development of early puberty and to examine their relationship with pelvic sonographic parameters. PATIENTS AND METHODS A total of 126 girls [patients - premature thelarche (PT) and CPP - and controls] were included in this study. Anthropometric and ultrasonographic evaluations were made by the same pediatric endocrinologist and pediatric radiologist, respectively. Pubertal stages were made according to the Tanner stages. Height, weight, and body mass index were measured as anthropometric measurements, and visceral, subcutaneous, and transabdominal fat thicknesses were measured in sonographic evaluation. RESULTS The study population was divided into three groups: 44 healthy subjects to Group 1, 23 patients with PT to Group 2, and 59 patients with CPP to Group 3. When we evaluated the anthropometric and ultrasonographic parameters according to pubertal status, significant differences, especially between Group 1 and Group 3, were observed in all data. In the multiple logistic regression analysis, the endometrial thickness (OR = 7.521, p < 0.001) and VFT (OR = 1.530, p < 0.001) were found to be independent predictors of precocious puberty. CONCLUSIONS It has been found that VFT and endometrial thickness measurements, which are evaluated quickly and accurately by USG, are important predictors of prepubertal precociousness.

Abstract
AIMS The aim of this non-systematic review was to provide a practical guide for clinicians on the evidence for central sensitisation in chronic osteoarthritis (OA) pain and how this pain mechanism can be addressed in terms of clinical diagnosis, investigation and treatment. METHODS The authors undertook a non-systematic review of the literature including a MEDLINE search (search terms included central sensitisation, osteoarthritis, osteoarthrosis) for relevant and current clinical studies, systematic reviews and narrative reviews. Case reports, letters to the editor and similar literature sources were excluded. Information was organised to allow a pragmatic approach to the discussion of the evidence and generation of practical recommendations. RESULTS There is good evidence for a role of central sensitisation in chronic OA pain in a subgroup of patients. Clinically, a central sensitisation component in chronic OA pain can be suspected based on characteristic pain features and non-pain features seen in other conditions involving central sensitisation. However, there are currently no diagnostic inventories for central sensitisation specific to OA. Biomarkers may be helpful for confirming the presence of central sensitisation, especially when there is diagnostic uncertainty. Several non-pharmacological and pharmacological treatments may be effective in OA patients with central sensitisation features. Multimodal therapy may be required to achieve control of symptoms. DISCUSSION Clinicians should be aware of central sensitisation in patients with chronic OA pain, especially in patients presenting with severe pain with unusual features.

Abstract
AIM The aim of this study was to translate the questionnaire into Turkish and to investigate the test-retest reliability, construct validity and its sensitivity to change following physical therapy. METHODS The questionnaire was translated into Turkish using the forward and backward translation technique. Test-retest reliability was assessed with the correlation coefficients. Scale analysis for internal validity, the Cronbach's alpha score was calculated. Construct validity was tested with principal components analysis and was also tested with divergent validity. Following three weeks of treatment, sensitivity to change and responsiveness of the questionnaire was assessed. RESULTS The questionnaire was applied on 55 patients and high correlations were found on the repeated items 48 hours later. In the scale analysis, the Cronbach's alpha score was found as 0.911 for the total questionnaire. Two factors were found compatible with the original questionnaire with principal components analysis. These two factors explain 61.647% of the total variance in the questionnaire performed on 150 patients. In divergent validity, the fear avoidance beliefs were found in low correlation with the clinical variables. Sensitivity to change and responsiveness of the FABQ was found to be low. CONCLUSIONS FABQ has sufficient psychometric features for its applicability in the Turkish population with subacute and chronic low back pain.

Abstract
The purpose of this study was to determine whether a measurable decrease in isokinetic (dynamic) and isometric (static) hand strengths occurs in carpal tunnel syndrome (CTS) patients. Eighteen CTS patients and 20 healthy controls were included in the study. Isokinetic (eccentric and concentric) and isometric grip and pinch strengths were measured with a Biodex System 3 dynamometer (Biodex Medical System, Inc. New York). All strength measurements, except isometric and isokinetic (concentric/eccentric) three-point pinch and isokinetic (concentric) tip pinch, revealed statistically significant differences between CTS patients and controls. Measurable decrease in hand strengths may exist in CTS despite normal manual assessments. Although both isokinetic (dynamic) and isometric (static) dynamometers are capable of detecting this decrease, neither technique seems better than the other.

Abstract
PURPOSE To evaluate the results of extracapsular cataract extraction (ECCE) and phacoemulsification (PHACO) performed in previously vitrectomized eyes. MATERIAL AND METHOD In this retrospective study, 56 vitrectomized eyes that had ECCE and 60 vitrectomized eyes that had PHACO were included in the study group while 65 eyes that had PHACO in the control group. The evaluated parameters were the incidence of intra-operative and postoperative complications (IPC) and visual outcomes. Chi-squared, independent samples and paired samples tests were used for comparing the results. RESULTS Deep anterior chamber (AC) was significantly more common in the PHACO group of vitrectomized eyes (PGVE) and observed in eyes that had undergone extensive vitreous removal (p < 0.05). Except for this there were no significant differences in the rate of IPC between the ECCE group and the PGVE (p > 0.05). Some of the intra-operative conditions such as posterior synechiae, primary posterior capsular opacification (PCO) and postoperative complications such as retinal detachment (RD), PCO were significantly more common in vitrectomized eyes than the controls (p < 0.05). There was no significant difference in the visual acuity gain between the ECCE group and the PGVE (p > 0.05). CONCLUSION Deep AC is more common in eyes with extensive vitreous removal during PHACO than ECCE. Decreasing the bottle height is advised in this case. Except for this, the results of ECCE and PHACO are similar in previously vitrectomized eyes. Posterior synechiaes, primary and postoperative PCO and RD are more common in vitrectomized eyes than the controls.

Abstract
PURPOSE To compare the symptoms, signs, and results of objective tests for dry eye syndrome (DES) in type 1 diabetes mellitus (T1DM) patients and controls. METHODS A total of 104 children with T1DM and 104 age- and sex-matched controls were compared in terms of the symptoms, signs, and results of objective tests for DES. Duration of T1DM, presence of diabetic retinopathy, mean hemoglobin A1c level, pubertal status, and a history of accompanying autoimmune disease were noted in T1DM group. Analysis of variance, multivariate regression analysis, Student t, Mann-Whitney U, and chi-square tests were used for statistical analysis. RESULTS A total of 15.4% of diabetic children complained of dry eye symptoms, versus 1.9% of the controls (p=0.029). Dry eye signs were detected in 7.7% of diabetic children, versus 0.96% of controls (p=0.034). Tear break-up time (TBUT) and Schirmer test results were significantly lower in T1DM group than controls (p=0.018, p=0.024, respectively). A total of 7.7% of diabetic children had definite and 0.96% had probable diagnosis of DES, versus none of the controls (p=0.03). TBUT and Schirmer test results were significantly lower in patients with more than 10 years duration of T1DM (p<0.001 for both). CONCLUSIONS The prevalence of symptoms, signs, and definite diagnosis of DES are higher and basal tear secretion and tear film stability are lower in diabetic children than controls. Duration of T1DM is the only disease-related variable which is associated with basal tear secretion and tear film stability.

Abstract
BACKGROUND AND PURPOSE Iodine deficiency and hypothyroxinemia have a negative effect on the development of the central nervous system during fetal and early postnatal life. MR spectroscopy is a sensitive technique for detecting the changes of brain metabolites in various neurodevelopmental disorders. By using MR spectroscopy, we aimed to show the decrease in N-acetylaspartate (NAA) levels in neonates with hypothyroidism who were born in iodine-deficient areas and its normalization with early thyroxine therapy. METHODS Eight congenital hypothyroid and 8 healthy full-term neonates were chosen as study and control groups, respectively. Serum thyroid hormones and median urinary iodine concentration of the neonates and their mothers were measured. Measurements of NAA, choline (Cho), and creatine (Cr) were made in frontal white matter, parietal white matter (PWM), and the thalamus with MR spectroscopy, first at 5-7 days of life and after 8 weeks of thyroxine therapy in the study group and at the same time in the control group. RESULTS The patient group had significantly lower NAA/Cr ratios in PWM and the thalamus (P < .05, for each), whereas the difference between Cho/Cr ratios of the 2 groups before therapy was not significant. After 8 weeks of thyroxine therapy, measurements did not show significant difference between study and control groups. CONCLUSION MR spectroscopy performed in neonates with hypothyroidism reveals that intrauterine hypothyroxinemia due to iodine deficiency results in significant decrease in NAA levels in PWM and the thalamus and that the normalization of NAA levels is achieved with early thyroxine therapy.

Abstract
INTRODUCTION Colonoscopy is currently supposed to be the best screening tool for colorectal cancer. However, the acceptance of the population is very poor although it has been included in screening programs in the German health system since 2002. Therefore, evaluation of additional screening tools seems to be of great interest. Recently testing for fecal occult blood (FOBT), genetic alterations or alterations in tumor metabolism (e.g., tumor M2-PK) are under investigation. METHODS The use of M2-PK measurement in the feces has been reported in 6 studies until today. The data of these studies were analyzed and critically reviewed. RESULTS The overall sensitivity of M2-PK is 77.9% concerning CRC. Specificity ranges from 74.3-83.3%. Overall sensitivity for adenomas is 45.9%, increasing to 61.1% for adenomas > 1 cm. A high percentage of positive results (90.4%) was also observed in patients with chronic inflammatory bowel disease. CONCLUSIONS Compared to FOBT or genetic testing the M2-PK test seems to be superior for CRC screening. Concerning handling, effectiveness and analysis, M2-PK seems to be a good possibility for large scale-screening of colorectal carcinoma. It might even be used to detect larger adenomas. Elevated levels of M2-PK in patients with acute and/or chronic inflammatory bowel diseases are probably due to proliferation of epithelial cells and leucocytes in the inflammatory area.

Abstract
INTRODUCTION The aim of the study was to determine the prevalence of vitamin D deficiency, secondary hyperparathyroidism (sHPT), generalized bone pain and predictors of vitamin D deficiency in a cohort of 994 healthy adult urban residents (589 males, 405 females; age range: 16-69 years) consisting of 101 Germans, 327 Turkish residents of Turkey and 566 Turkish immigrants living in Germany. METHODS The mean (+/- standard deviation) for 25-hydroxyvitamin D [25(OH)D] and biointact parathyroid hormone (BioPTH) for the German men and women was 68.4 nmol/l and 26.7 pg/ml, respectively. Turkish residents of Turkey had a mean 25(OH)D and BioPTH of 40.6 nmol/l and 27.5 pg/ml, respectively, whereas Turkish residents of Germany had a 25(OH)D of 38.1 nmol/l and a BioPTH of 35.6 pg/ml. RESULTS Vitamin D insufficiency was common among Turkish nationals independent of whether they lived in Turkey or Germany; 75% had 25(OH)D levels of <50 nmol/l. Turkish females had a higher prevalence of 25(OH)D deficiency (<25 nmol/l) than Turkish males: 30 and 19% of Turkish females living in Germany and Turkey were severely vitamin D deficient compared to 8% and 6% of Turkish males living in Germany and Turkey, respectively. With respect to BioPTH levels, 31% of Turkish females and 21% of Turkish males had elevated BioPTH levels in contrast to only 15% of females and 4% of males living in Turkey. Unconditional logistic regression analysis identified the most important predictors for low 25(OH)D levels as sex, body mass index, lack of sun exposure and living at a higher latitude. Additionally, wearing a scarf and number of children were found to be an independent risk factor for vitamin D deficiency in Turkish women living in Turkey and Germany. A strong correlation between low 25(OH)D levels and higher rates and longer duration of generalized bone and/or muscle aches and pains (often diagnosed as fibromyalgia) was observed. CONCLUSION Secondary hyperparathyroidism and vitamin D deficiency was found to be common among Turkish immigrants living in Germany, especially in veiled women. Therefore, the monitoring of vitamin D status--i.e. 25(OH)D and PTH--in Turkish immigrants is warranted and once a deficiency is identified, it should be appropriately treated.

Abstract
The metabolite changes in the brains of children with poorly controlled type 1 diabetes mellitus (DM) were investigated by proton magnetic resonance spectroscopy (MRS). A total of 30 subjects and 14 age-matched healthy volunteers underwent single-voxel MRS (TE: 136). The duration of disease, medication, presence of hypoglycaemia episodes and the level of haemoglobin A1C (HbA1C) in the patients were noted. Voxels were placed in the pons, left basal ganglion (LBG) and left posterior parietal white matter (PPWM). N-acetylaspartate (NAA)/creatinine (Cr) and choline (Cho)/Cr ratios were calculated. The average HbA1c level was 11.9 +/- 3.4 (8.2-19.4). The average number of keto-acidosis episodes was 1.9 +/- 2.2 (0-9) and the average number of daily insulin injections was 2.8 +/- 0.97 (2-4). MRS revealed lower NAA/Cr and Cho/Cr ratios in the pons and lower NAA/Cr ratio in the PPWM of patients with DM than in control subjects. No significant correlation was observed between the number of hypoglycaemia episodes and metabolite ratios. Metabolic abnormalities have been observed by MRS in the brain of poorly controlled type 1 DM children. These metabolic changes, in particular in the pons region, include a decrease in NAA, indicating neuronal loss or functional impairment, and likely explanations for a decrease in Cho may be dynamic changes in membrane lipids and/or decreased membrane turnover.

Abstract
We report a case with Robinow syndrome which has been rarely reported in the literature. A male newborn who had fetal face appearance (broad and prominent forehead, hypertelorism, small saddle nose, anteverted nostrils, glabellar nevus flammeus, malar hypoplasia, down-turned mouth and retrognathia), mesomelic limb shortening, hemivertebra and genital hypoplasia was diagnosed as Robinow syndrome. Elevated levels of both basal and stimulated testosterone and dihydrotestosterone were found along with normal baseline levels of gonadotropins. These endocrinologic studies were suggestive for an androgen insensitivity. Mental and motor development of the infant were normal at 3 and 6 months of age. Because of the high level of consanguineous marriages in Turkey, we may expect a higher incidence of the autosomal recessive form of the syndrome. This gives a high recurrence risk and makes prenatal diagnosis an important option for future pregnancies in the families.

Abstract
STUDY OBJECTIVE To assess the prevalence of risk factors for coronary heart disease (CHD) in a lower middle-class urban community of Turkey. DESIGN Cross-sectional study in an age- and sex-stratified random community sample with equal sample size per stratum. Direct age-standardization using the standard world population to allow international comparison of findings. Logistic regression modelling to identify risk factors for obesity. SETTING Gülveren, a residential area in Ankara, total population 23,000 persons. PARTICIPANTS A total of 1672 adults aged 25-64 years and resident in the study community were interviewed, 1272 (76.1%) of those came for physical examination. MAIN RESULTS The age-standardized prevalence of hypertension according to WHO MONICA criteria was 18.6% (95% confidence interval: 16.1-21.1%) among women and 12.3% (9.7-14.9%) among men; of obesity (body mass index, BMI > or =30 kg/m2) 51.0% (47.6-54.3%) among women and 15.1% (12.0-18.2%) among men; of current smoking 20.1% (17.5-22.6%) among women and 64.8% (61.4-68.2%) among men; of hypercholesterolaemia 20.1% (17.4-22.9%) among women and 13.8% (10.8-16.8%) among men; and of low high density lipoprotein (HDL) 48.4% (44.8-52.1%) among women and 40.6% (36.0-45.2%) among men. In the regression model, age, female sex, non- and ex-smoking were associated with obesity. CONCLUSIONS The prevalence of smoking, obesity and low HDL is high in this urban, lower middle-class population, even in comparison with industrialized countries. Unexpectedly, women have less favourable CHD risk profiles than men, except for smoking. Preventive action should be community-wide and address the common risk factors simultaneously to avoid replacement effects such as becoming obese after quitting smoking.

Abstract
The aim of this study was to describe the epidemiological and clinical features of an outbreak due to Chryseobacterium meningosepticum. During a 11-day period, the outbreak was observed among four newborns in a neonatal intensive care unit (NICU) in a teaching hospital. All patients yielded C. meningosepticum in their blood cultures, in addition one was colonised in the throat. Antimicrobial susceptibility assay showed complete resistance to penicillins, cephalosporins, aminoglycosides, imipenem, aztreonam, and tetracycline, sensitivity to ciprofloxacin and trimethoprim-sulfamethoxazole. All patients were empirically treated with amikacin and meropenem. The neonate who was the first to develop sepsis died before the culture result. When C. meningosepticum was identified, antimicrobial therapy was changed to a combination of ciprofloxacin, rifampicin and vancomycin, and three neonates were treated successfully. Environmental screening recovered C. meningosepticum from two venous catheter lines and one nutritional solution that was opened by health care staff and used for two neonates. Arbitrary primed polymerase chain reaction and antibiogram typing indicated that all isolates were epidemiologically related. This study demonstrates that rapid selection of appropriate antibiotics is critical for clinical cure and standard precautions should be reconsidered to limit the spread of this bacterium on the NICU in our hospital.

Abstract
The purpose of this study was to describe the magnetic resonance imaging findings of granulomatous hepatitis on T1-weighted, T2-weighted and postgadolinium images. Eight patients with histopathological diagnosis of granulomatous hepatitis were evaluated in this study. MRI examinations included precontrast T1-weighted breath-hold spoiled gradient echo, breathing independent STIR sequences, and T1-weighted breath-hold spoiled gradient-echo sequence following after i.v. gadolinium administration in arterial, intermediate and late phases. Diffuse nodular liver involvement was visualized in all patients. Nodules were consistent with granulomas and were 0.5-4.5 cm in diameter. Caseating granulomas were intermediate and high signal on T2-weighted, low signal on T1-weighted images. They revealed no enhancement in two patients, and enhanced in one patient. Noncaseating granulomas revealed intermediate signal on T1, and T2-weighted images and increased enhancement on arterial phase images with persisting enhancement in late phase images. Portal lymph nodes were visible in five patients. Splenomegaly was present in five patients. Granulomatous hepatitis has spectrum of MRI features, to be considered in differential diagnosis with other diffuse nodular liver pathologies.

Abstract
Morgagni hernia (MH) is the least common type of congenital diaphragmatic hernias. Although its course is often asymptomatic, it may be associated with various respiratory and gastrointestinal symptoms. We describe 7 children with MH during a 5-year period in three pediatric centers in Turkey. All children had acute or chronic respiratory symptoms; cough was the most frequent. The diagnosis was made by posterior-anterior (PA) and lateral chest X-rays. The PA chest X-rays showed a homogenous mass in 2 and a gas-filled cystic image in 3 children in the right cardiophrenic angle. A retrocardiac homogeneous density in one child, and bilateral consolidation in lower lung areas in another child were also seen. All lateral chest X-rays showed gas-filled bowel loops above the diaphragm. The diagnosis was confirmed by barium-contrast radiograph. Four patients had five additional anomalies, i.e., ventricular septal defect, right inguinal hernia, congenital hip dislocation, pectus carinatum, and obstruction of the uretero-pelvic junction. All of the hernias were repaired by an abdominal approach. There were no complications or recurrences during follow-up. In conclusion, MH should be considered in the differential diagnosis of cases of long-standing respiratory symptoms and/or when an unexplained radiological image, especially on the right cardiophrenic area, is present.

Abstract
Diabetes mellitus and glucose dysregulation have significant effects on the circulating level of insulin-like growth factor-I (IGF-I) and IGF binding proteins (IGFBPs). In the present study, serum and urine IGFBP (IGFBP-1, -2, and -3) and serum IGF-I and -II levels were measured by radioimmunoassay (RIA) in 27 patients with type 1 diabetes aged 9 to 48 years compared with 9 healthy subjects aged 10 to 28 years. The patients were divided into 3 groups according to the amount of albumin excreted in 24 hours. The macroalbuminuria group (>500 mg/24 h) had elevated serum IGFBP-1 and -2 and decreased IGF-I levels (P < .01 v normal controls). Serum IGFBP-3 and IGF-II were not different among the patient groups and controls (P > .05). The mean urinary IGFBP-1 was decreased in all 3 patient groups compared with the controls (P < .05). Urinary IGFBP-2 and IGFBP-3 were increased in patients with macroalbuminuria. Immunoblot analysis showed increased low-molecular-weight fragments of urinary IGFBP-2 in the poorly controlled diabetics, and direct evidence for increased urinary IGFBP-2 proteolytic activity could be demonstrated in both the microalbuminuric and macroalbuminuric groups. Low-molecular-weight fragments of urinary IGFBP-3 were also increased in both the microalbuminuric and macroalbuminuric groups. In conclusion, alterations of IGFBPs in urine and serum are related to metabolic control in diabetic patients, and there is an increase of urinary IGFBP-2 protease activity in poorly controlled diabetics. The changes in serum IGFBP concentrations (eg, increases in IGFBP-1 and IGFBP-2) may lead to alterations in the availability of IGF-I to peripheral tissues.

Abstract
Eosinophilic fasciitis is a rare disease in children. Although changes similar to linear scleroderma have been reported, the outcome is usually good. In this report, a 10-year-old boy who developed eosinophilic fasciitis without a good response to steroids is presented. He progressed to linear scleroderma within months. Our case reinforces the hypothesis that eosinophilic fasciitis may be an early manifestation or a variant of localized scleroderma similar to the other cases in the literature.

Abstract
Turkish people represent the majority of immigrants in Germany. Even though a high proportion of Turks has been living in Germany since about 20 years, little is known about risk factors of coronary heart disease (CHD) in this population. In this study a sample of 325 male and 155 female Turks are investigated, who voluntarily underwent a health check-up in Germany. Data about the presence of CHD, risk factors and blood parameters were collected. Mean residence time was 21 and 17 years (males/females). A low percentage of female participants was observed compared to the general Turkish population in Germany. Age adjusted prevalence of CHD reached 9.5% in males and 6.7% in females, respectively. Dyslipoproteinemia (DLP) showed the highest prevalence of all risk factors investigated in both genders. Total cholesterol (TC) levels were comparable to those of other western countries and remarkably higher than reported for the population in Turkey. Besides this, low high density lipoprotein-cholesterol (HDL-C) and apolipoprotein A-I (ApoA-I) levels could be found in the majority of the sample. The highest odds ratios for CHD were estimated for stress and hypertension in males and obesity in females. It is concluded that Turkish immigrants in Germany showed an assimilation of lipid pattern to western populations. However, reasons for low HDL-C levels remain unclear. Changes in the lipid metabolism chiefly seem to contribute to the risk factor pattern of Turkish immigrants in Germany.

Abstract
We present a 12-year-old boy who developed subacute thyroiditis during the course of rapidly progressive glomerulonephritis due to Henoch-Schonlein purpura (HSP) proven by clinical findings and percutaneous renal needle biopsy. The thyroid gland of the patient suddenly enlarged with mild tenderness while he was on steroid and dipyridamole therapy. Thyroid hormone levels revealed T3 0.31 ng/ml (nl: 0.52-1.75 ng ml), T4 2.53 ug/dl (nl: 4.8-12.8 ug/dl), free T3 0.80 pg/ml (nl: 2.14-5.34 pg/ml), free T4 0.2 ng/dl (nl: 0.73-1.95 ng/dl) and TSH 1.02 U/ml (nl: 0.36-3.25 U/ml). Antimicrosomal antibody was negative while antithyroglobulin antibody was slightly positive (1/80+). Hypoactivity with a spotty pattern was demonstrated by thyroid scanning. Serologically proven mumps infection was detected and may have been a triggering factor in the development of both HSP and subacute thyroiditis.

Abstract
Brain stem auditory evoked response (BAER), visual evoked response (VER) and nerve conduction velocities (NCV) were studied in 18 insulin-dependent diabetic children between the ages of 3.5 and 16 years (mean 9.0 +/- 3.2 years). The results were compared with those of age-matched controls. The VER latencies of the diabetic children in the right eye and left eye were significantly prolonged when compared with the control group. NCV of n. peroneus and the latency of sensorial n. medianus were significantly impaired when compared with the control group. Although the latencies of waves III, IV and V of the right ear and the interpeak latencies of I-III, I-V, III-V of both ears were prolonged, the comparison with the control group was not significant. The beta 2 microglobulin levels of the diabetic patients were significantly higher than those of the control group. There was a positive correlation between the beta 2 microglobulin and the BAER interpeak latencies of wave III-V in both ears (r: 0.51 p < 0.01). There was also a positive correlation between NCVs of n. peroneus and n. medianus (motor and sensorial) with beta 2 microglobulin (r: 0.52 p < 0.01) and between VER latencies (r: 0.52 p < 0.01) of both eyes separately. In our study the prolonged latencies of VER and BAER were detected in the absence of clinical abnormalities in visual and hearing systems.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A signal averaged ECG is a useful tool for detecting low-amplitude, high frequency electrical potentials in the terminal portion of QRS. There is a close association between abnormal signal averaged ECG and coronary heart disease. In this study we evaluated late potentials and total QRS duration determined by this technique in diabetic children with and without good glycemic control. The signal averaged ECG of 20 children with diabetes mellitus and nine healthy age-matched controls were compared. The total QRS duration was longer in diabetic children than in controls (104.6, and 97.9 ms vs. 82.7 ms, P < 0.0005). Late potentials were not observed in the patient and control groups. The RMS voltage of the QRS complex in the last 40 ms was significantly lower in the diabetic group compared to the control group. There was no significant difference in the signal averaged ECG indexes between the two diabetic groups determined by the glycemic control state. These findings suggested that the children with diabetes mellitus frequently have intraventricular conduction disturbance regardless of glycemic control condition.

Abstract
Heart rate variability (HRV) is a noninvasive index of the neural activity of the heart. Although also influenced by the sympathetic activity of the heart, HRV is essentially determined by the vagal stimulation of the heart. Several HRV abnormalities have been described in adults with diabetes mellitus. However, there are few data on HRV in children with diabetes mellitus. In the present study, HRV was assessed in seven healthy children, 10 diabetic children with good glycemic control and 11 diabetic children with poor glycemic control. All had normal standard cardiac autonomic function tests, obtained from 24-h Holter tapes. HRV was measured by calculating six time-domain (mean R-R interval (RR), standard deviation of the R-R interval [SDRR], standard deviation of the mean of 288 R-R intervals [SDANN], the mean of the 288 standard deviations computed for each 5-min period [SD], percentage of differences of adjacent R-R intervals of > 50 msec for the entire 24 h [pNN50], and the root mean square of successive differences [rMSSD]) and four frequency-domain (low frequency [LF], high frequency [HF], total heart rate power spectra, and LF/HF ratio) indexes. SD, pNN50, rMSSD, LF, HF and total heart rate power spectra were markedly and significantly reduced in diabetic children with poor metabolic control. The 24-h variation of low- and high-frequency components of heart rate power spectra of the latter children had a different shape. Thus, diabetic children with poor metabolic control (elevated HbA1c and B2M levels) have a low HRV compared to those diabetic children with good control and healthy children.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This study introduces a patient who has thiamine and thiamine pyrophosphokinase (TPKase) enzyme deficiency associated with diabetes mellitus, sensorineural deafness and thiamine-responsive megaloblastic anemia. Diabetes mellitus was diagnosed when she was 20 months old. After 1 year, macrocytic anemia developed and the thiamine therapy was started at 75 mg/day. During the follow-up, the insulin requirement decreased and even ceased, and macrocytic anemia improved with thiamine treatment. After thiamine therapy was ceased an increase in insulin requirement was observed and macrocytic anemia developed again.

Abstract
Hypocalcemia is a relatively uncommon but reversible cause of left ventricular dysfunction in infants and children. A 30-day-old boy with idiopathic hypocalcemia presented with congestive heart failure and convulsive seizures. He had no evidence of underlying cardiac disease. The cardiac failure responded to calcium therapy. It is suggested that hypocalcemia should be considered as a possible cause of left ventricular dysfunction in infants.

Abstract
Serum total and free thyroid hormones, reverse T3 (rT3), thyroxin binding globulin (TBG) and thyroid stimulating hormone (TSH) concentrations were measured in 35 epileptic patients receiving anticonvulsants (phenobarbitone, phenytoin). There was a significant reduction found in total thyroxine (TT4), free thyroxine (FT4), total triiodothyronine (TT3), free triiodothyronine (FT3) and rT3 in the group treated with, phenytoin. The thyroid hormone levels were within normal limits in the group receiving phenobarbitone.

Abstract
A Turkish family of seven individuals (two parents and five offspring) is described in which three children presented with isolated GH deficiency type IA, as defined by Illig et al. The gene deletion responsible for the isolated GH deficiency was characterized by Southern blotting and hybridization analysis of genomic DNA using a 32P-labeled hGH cDNA clone as a probe. In the affected patients, a total of approximately 45 kilobases of DNA, encompassing the human (h) GH-1, human chorionic somatomammotropin-L (hCS-L), hCS-A, and hGH-2 genes, were deleted. The end points of the deletion lay within two regions of highly homologous DNA sequence situated 5' to the hGH-1 gene and 5' to the hCS-B gene. The retention of only the hCS-B gene was associated with normal weight and length at birth and normal postpartum lactation in the mother heterozygous for the deletion. The parents, who are consanguineous, both presented with a DNA restriction pattern consistent with heterozygosity for this deletion.

Abstract
Non-classical adrenal hyperplasia due to 21-hydroxylase enzyme deficiency (NC21OHD) causes hirsutism, acne and menstrual irregularities in women. Clinically, patients with NC21OHD may be indistinguishable from other hyperandrogenic women, as they all present with similar symptoms. An elevated response of cortisol precursors like 17 alpha-hydroxyprogesterone (17-OHP) to ACTH stimulation is a valuable diagnostic criteria. In this study, 32 hirsute adolescent girls, aged 13-19 years, underwent i.v. adrenocorticotrophic hormone (ACTH) (Synacthen 0.25 mg) stimulation test. The results were compared with those of the controls. The plasma levels of 17 alpha-hydroxyprogesterone, cortisol, dehydroepiandrosterone sulphate (DHEA-S), androstenedione, testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH) and prolactin were established before, and 60 min after the infusion of ACTH to both patients and controls. Six patients demonstrated an increase in both the 17 alpha-hydroxyprogesterone levels and the 17 alpha-hydroxyprogesterone/cortisol ratio on ACTH stimulation, almost twice that of the mean +/- 2SD in the control group and ten times that in one patient. Six patients with abnormal elevation of 17 alpha-hydroxyprogesterone were considered heterozygotes for 21-hydroxylase enzyme deficiency, and one patient was presumed to have NC21OHD. Human leukocyte antigen (HLA) analysis supported these diagnoses. In this study, the incidence of NC21OHD in hirsute adolescent girls in our population was investigated, and NC21OHD was found in only one of 32 patients.

Abstract
Familial isolated growth hormone deficiency type IA results from homozygosity for either a 6.7-kb or a 7.6-kb hGH-1 gene deletion. Genomic DNA was extracted from circulating lymphocytes of 78 subjects with severe isolated growth hormone deficiency (height less than -4.5 SD score) and studied by polymerase chain amplification and by restriction endonuclease analysis looking for gene deletions within the hGH-gene cluster. The individuals analyzed were broadly grouped into three different populations (North-European, n = 32; Mediterranean, n = 22; and Turkish, n = 24). Ten out of 78 patients studied presented with an hGH-1 gene deletion; eight out of these 10 showed a 6.7-kb gene deletion, the remaining two a 7.6-kb hGH-1 gene deletion. Five of the 10 subjects developed anti-hGH antibodies to hGH replacement followed by a stunted growth response. Family studies of the affected patients were performed, revealing consanguinity in all the families, and the corresponding heterozygosity for the deletion was present in each of the parents. The results of our study revealed a prevalence for an hGH-1 gene deletion in three out of 32 North-European, three out of 22 Mediterranean, and four out of 24 Turkish patients with growth hormone deficiency (height less than 4.5 SD score). These data are important for prenatal diagnosis of at-risk pregnancies and for families at risk for recurrence and underline clearly the fact that the hGH-I gene deletion represents a common cause for growth hormone deficiency associated with severe growth retardation (height less than -4.5 SD score).

Abstract
Radiological sacroiliitis in Behçet's syndrome (BS) has been a subject of controversy. We have examined pelvic radiographs of 38 patients with BS and 28 age and sex matched controls which we reported previously, and also 17 with ankylosing spondylitis (AS), 27 with non-renal familial Mediterranean fever (FMF), and 33 with primary osteoarthrosis (OA). Initially, five observers assessed radiographs on two different occasions according to the New York criteria for sacroiliitis in a blind protocol. Later, three of them examined the various possible abnormalities of the sacroiliac (SI) joints after training sessions. Although the inter- and intraobserver variation was quite high, all observers found the expected changes in patients with AS. The abnormalities detected in the other diseases were either mild, inconsistent, or both. Erosions were confined to patients with AS, and osteophytes and glenoid sulci to patients with OA. We conclude that high observer variation in interpreting a film of the anteroposterior (AP) view of the pelvis for sacroiliitis may be a major cause of reported 'sacroiliitis' in BS and FMF.
