High frequency of transient congenital hypothyroidism among infants referred for suspected congenital hypothyroidism from the Turkish National screening program: thyroxine dose may guide the prediction of transients.

PURPOSE: We aimed to determine the frequency of transient congenital hypothyroidism (TCH) in 17 participating centers in Türkiye, evaluate the etiological distribution in permanent congenital hypothyroidism (PCH) cases, and investigate the role of laboratory and clinical findings in predicting TCH. METHODS: This retrospective observational multicenter study included patients from 17 pediatric endocrinology centers identified by "National Newborn Screening Program" (NNSP) who were born in 2015 and followed for 6 years. Demographic, clinical, and laboratory information of the cases were compiled through the database http://cedd.saglik-network.org (CEDD-NET). RESULTS: Of the 239 cases initially treated for CH, 128 (53.6%) were determined as transient in whom a trial of levothyroxine (LT4) withdrawal was performed at a median age of 36 (34-38) months. Among the patients with PCH (n = 111), thyroid dysgenesis was diagnosed in 39.6% (n = 44). The predictive factors for TCH were: LT4 dose at the withdrawal of treatment, and initial newborn blood screening (NBS)-TSH level. Based on the receiver operating characteristic (ROC) curve analysis to predict optimal cut-offs for TCH predictors, LT4 dose < 2.0 µg/kg/day at treatment discontinuation was predictive for TCH and was associated with 94.5% specificity and 55.7% sensitivity, with an area under the curve (AUC) of 0.802. The initial NBS-TSH level value < 45 µIU/mL was predictive for TCH with 93.1% specificity and 45.5% sensitivity, with an AUC of 0.641. In patients with eutopic thyroid gland only LT4 dose < 1.1 µg/kg/day at withdrawal time was predictive for TCH with 84.7% sensitivity and 40.4% specificity, with an AUC of 0.750. CONCLUSION: According to our national follow-up data, the frequency of TCH was 53.6%. We determined the LT4 dose < 2.0 µg/kg/day at discontinuation of treatment and the initial NBS-TSH level < 45 µIU/mL as the best cut-off limits to predict TCH.

Apraxia in Parkinson's disease and multiple system atrophy.

OBJECTIVE: To determine praxis function in patients with Parkinson's disease (PD) and multiple system atrophy (MSA). METHODS: Nineteen patients with PD and 16 patients with probable MSA were recruited into study. Twenty-five age-matched, healthy subjects were included as controls. The Mayo Clinic praxis test battery was applied. Pantomime tasks, including oral/facial, trunk, and upper extremity movement, were used to evaluate ideomotor apraxia (IMA). Sequential tasks, including Luria test for ideational apraxia (IDA) and use of actual objects, were also tested. In addition, Standardized Mini Mental Test (MMSE), Hamilton Depression (HAM-D), and Anxiety (HAM-A) Scales were used. RESULTS: Mean ages of the study participants were 66 +/- 7, 68 +/- 5, and 65 +/- 7 years in PD, MSA, and control groups, respectively. Mean total praxis score was significantly lower for patients with PD (92.4 +/- 4) and MSA (75.9 +/- 18) than for controls (97.4 +/- 2) (P = 0.000). Transitive performances of upper extremities and sequential tasks were significantly impaired in patients with PD compared to control subjects (P < 0.05). There was no correlation between total praxis scores and sum scores of tremor, bradykinesia, and rigidity of both of the upper limbs of patients with PD. Subgroup praxis scores were substantially worse in MSA group (P < 0.0001). Compared to control subjects, mean scores for MMSE, HAM-D, and HAM-A tests were significantly worse in MSA group, but, for PD patient group, only HAM-A scores were worse. CONCLUSION: Our results indicate that although not a presenting symptom, IMA and IDA may be features of MSA and, to a lesser degree, of PD. Also, it seems to be unrelated to the motor features of patients with PD.

Anthropometric measurements of term neonates from a state hospital in Turkey.

To determine regional percentile values and compare them with currently used national and international curves, we determined the birth weight, height and head and chest circumference of 3688 term neonates born in a state hospital in the Anatolian part of Istanbul, Turkey. Mean birth weight, height and head and chest circumference were 3334 (SD 494) g, 48.3 (SD 2.2) cm, 34.4 (SD 1.3) cm and 32.8 (1.9) cm respectively. For both boys and girls, the current Turkish national percentile curves overestimate the birth weight, height and head circumference at the 10th percentile. For boys, the national curves and those from the USA underestimate birth weight of neonates above the 90th percentile.

Association of low cholesterol with primary intracerebral haemorrhage: a case control study.

OBJECTIVES: Epidemiological studies have shown that the incidence of intracerebral haemorrhage (ICH) is high in patients with low cholesterol levels. The aim of this study was to investigate the correlation between ICH and low cholesterol in cases of primary ICH. MATERIAL AND METHODS: Two hundred and fifty-nine patients with primary intracerebral haemorrhage and 137 healthy individuals were included in this study. Patients with prior cerebrovascular accident, secondary ICH, hereditary lipid metabolism disorders, thyroid diseases and those using lipid-lowering drugs were excluded. In all subjects, cholesterol levels were measured after 12 h of fasting. RESULTS: Mean cholesterol levels were 205.8 +/- 51.4 mg/dl in the ICH group and 230.2 +/- 38.9 mg/dl in the control group. Mean cholesterol levels of patients were significantly lower than the controls (P < 0.000). In ICH group, the frequency of patients who had very low cholesterol levels was significantly higher than the control group (P < 0.000). CONCLUSIONS: Individuals with lower cholesterol levels have an increased risk of ICH. Therefore, before treatment with statins, clinicians must be aware of the possible ICH risk.

For both boys and girls, the current Turkish national percentile curves overestimate the birth weight, height and head circumference at the 10th percentile. For boys, the national curves and those from the USA underestimate birth weight of neonates above the 90th percentile

Features associated with the development of hallucinations in Parkinson's disease.

OBJECTIVE: To identify features related to the development of hallucinations in Parkinson's disease (PD). MATERIALS AND METHODS: Seventy PD patients with hallucinations (group 1) and 60 PD patients without hallucinations (group 2) were evaluated for disease severity, presence of motor complications, rapid eye movement (REM) behavior disorder (RBD), and antiparkinsonian drug profile. The ages at the emergence of hallucinations and duration of disease in group 1 were matched with the ages at the last visit of those in group 2. RESULTS: Disease severity and presence of motor complications were similar in both groups. RBD was more frequently encountered among hallucinators than among non-hallucinators (P = 0.007). The mean duration and daily doses of levodopa and other dopaminergic drugs did not differ in both groups; however, the usage of anticholinergics and amantadine were significantly more frequent in group 2, unexpectedly. CONCLUSIONS: The presence of RBD was significantly more common in hallucinators; however, severity of PD, duration and daily doses of dopaminergic drugs were not associated with the emergence of hallucinations.

Cardiac effects of a single course of antenatal betamethasone in preterm infants.

AIM: To show the effects of a single course of antenatal betamethasone on cardiac measurements and systolic functions in premature newborn infants. METHODS: Seventy six newborn infants with a gestational age of 25-33 weeks were included in the study. They were first classified according to their gestational age: 25-29 weeks (n = 28) and 30-33 weeks (n = 48). They were then reclassified as betamethasone positive (mother received one course of betamethasone) or betamethasone negative (mother did not receive any antenatal glucocorticoid treatment). Cross sectional M mode echocardiographic scans were performed during the first three postnatal days and at the end of the first and third weeks. Left interventricular septum (IVS), left ventricular posterior wall (LVPW), left ventricular end diastolic (LVED), and left ventricular end systolic (LVES) dimensions, aortic root (AO), and left atrial diameters (LAs) were measured. The IVS to LVPW ratio was calculated to identify asymmetrical septal hypertrophy. RESULTS: In neither group was any statistically significant difference noted in IVS, LVED, LVES, LVPW, LA, and AO measurements during the three cardiac ultrasonography scans. Systolic function, as assessed by fractional shortening, was not significantly different in infants who received betamethasone antenatally, in either age group. There was no difference in the IVS/LVPW ratios between those who received antenatal steroid and those who did not for the 25-29 week and 30-33 week groups during these three consecutive scans. CONCLUSION: One course of antenatal betamethasone did not affect the cardiac wall thicknesses and systolic function in premature infants.

Analysis of clinicopathological prognostic parameters in adenocarcinoma of the gastric cardia.

BACKGROUND: The optimal extent of resection for carcinoma of gastric cardia remains a subject of controversy. Although both total gastrectomy (TG) and proximal gastrectomy (PG) have their own advantages, similar survival rates were given for both. The main aim of this study is to investigate whether the extent of resection is an important prognostic factor in carcinoma of the gastric cardia. METHOD: Records of 60 patients with carcinoma of gastric cardia, operated on between the January 1989-January 1993 at Istanbul University, Cerrahpasa Medical Faculty Department of General Surgery, were reviewed retrospectively. The relationship between clinico-histopathological variables and 5-year survival was retrospectively analysed. RESULTS: Of the 14 clinico-histopathological variables, eight (age, local invasion, grade, lymphatic micro-invasion, depth of penetration, lymph node involvement, type of operation and stage of disease) were found to have a significant influence on survival. Among those clinico-histopathological variables that influenced 5-year survival on univariate analysis, only age (p = 0.0029) and depth of tumour penetration (p = 0.008) independently affected survival. CONCLUSION: According to our results, depth of tumour penetration and age are the only variables which were found to independently affect 5-year survival. Depth of tumour penetration may serve as a potential marker for a biologically more aggressive tumour. The extent of resection (TG vs. PG) does not affect the long-term survival of the adenocarcinoma of the cardia.

Factors influencing the duration of exclusive breastfeeding in a group of Turkish women.

This study was conducted to evaluate the influence of demographic characteristics, hospital practices, maternal psychosocial factors, and knowledge about infant feeding and breast milk on duration of breastfeeding. The mothers of 91 healthy, term infants delivered at a university hospital between June 1998 and December 1998, and first seen in the well-child unit within 10 days of delivery, participated in the study. Forty-nine (54%) infants were exclusively breastfed at 4 months of age. Cox regression analysis showed a negative association between formula supplementation during the hospital stay and duration of exclusive breastfeeding. The median age for starting non-breast milk liquids was 1 month for those who received formula in the hospital and 3 months for those who did not (P = .001). The hospital practices were more predictive of the duration of exclusive breastfeeding in this study group than mothers' knowledge of infant feeding or psychosocial factors. Thus, hospital practices should be reevaluated.
