Abstract

Background: Nephrotic syndrome is a chronic disease with frequent relapses and the accumulative dose of steroid play an important role in developing growth retardation.Aims: To detect the degree of growth retardation in long standing nephrotic syndrome and frequent relapsing nephrotic syndrome, and to identify the effect of nephrotic syndrome and steroid therapy on puberty.Patient and methods: A cross sectional study conducted in Child Central Teaching Hospital from the first of January to first of July 2008, on 108 patients with steroid responding nephrotic syndrome, 60 of them were males and 48 were females. All had anthropometric measurement of height and the assessment depend on Tanner growth centile for age and sex, so as the puberty staging according to Tanner staging. The ranges of the patients ages were 2-17y and the mean age was 11.5+4 y. 59.25% (64) were having steroid toxicity; no patient was on cytotoxic drug.Results: The results were shown that 52/ 108 (48.18%) of the patients have got growth retardation (2SD below the mean) Fifty of the patients were at pubertal age, 30 were males and 20 were females. 39 patients had delayed puberty (78%), 36 patients with delayed puberty had steroid toxicity (94.73%). There is a significant relationship between frequency of relapses, duration of illness and steroid toxicity with incidence of delayed puberty and growth retardation.Conclusions: There is a significant correlation between the growth retardation and the development of steroid toxicity. With frequent relapses and long standing nephrosis, there is a chance to develop growth retardation. Delayed puberty is more with steroid toxicity and it is more in males than females.

Abstract

Hypospadias is a relatively common congenital anomaly of the penis that arises in 2 to 8 of 1000 live births, often as an isolated anomaly. This anomaly is repaired surgically in the first year of life to improve the cosmetic appearance and establish a glanular position of the urinary meatus for voiding and deposition of semen later in life. The aim of this study is to evaluate the effectiveness of HCG hormonal manipulation in inducing penile growth in hypospadias boys before surgical repair , and the pattern of this growth and response , in addition to that this thesis try to add more knowledge to the etiology and pathogensis of one of these relatively common urogenital disorder.Patients and methods :-This small series thesis included 16 boys with an age ranged from 3-48 ms who had proximal and penoscrotal hypospadias with sever cordea .All boys received a full course of HCG treatment using the standard WHO protocol of HCG therapy in pediatric age group. The degree and rate of response to HCG therapy together with the pattern of penile growth have been measured and evaluated before and one week after HCG therapy using the student T – test for statistical analysis.Results :-At the end of HCG treatment penile growth has been achieved in all boys. The cordee decreased and penile length increased in all cases. The mean stretched penile length was changed from 18.68 pre HCG to 31.97 post treatment (P value < 0.001). The average penile length was nearly doubled after HCG treatment with an increase of 40% to 180% (mean 83%, P value < 0.001)What was very interesting and major finding that emerge during this study , is that the penile response and growth to HCG treatment was not universal over the whole shaft of the penis, with by far most of increment in penile length occurred proximal to urethral meatus and the percentage of penile growth was 262% (P value < 0.001) proximal to meatus , while it was only 24% not significant (P value > 0.001 ) distal to it . This disproportional penile growth causing the meatus to advance distally in all cases with a mean distal migration of urethral meatus was 9.75 mm (P value < 0.001).Conclusion :- HCG treatment in hypospadias was very effective in achieving sufficient penile growth that might facilitate the surgical outcome, the other finding is that hypospadias even the sever one is not at a fixed stage or degree, but it can easily be manipulated by hormonal treatment in addition to that, this study suggest that post natal response of hyposadias penis to HCG might provide a mirror that reflect its intra natal response during organogenesis and embryogenesis, and this thesis might provide a different insight toward the pathogenesis of hypospadias-chordea complex by diverting more attention and focusing toward a localized endocrinopathy that affect the tissue responsiveness to androgen.

Abstract

A relation for predicting the drag coefficient for the process of bubble growing in a convective surrounding (uniformly superheated pure liquids) was developed. The non-dimensional parameters governing the motion and heat transfer are identified and a theoretical study of the effects of the variation of these parameters is made. The drag coefficient decreases with time for all accelerations, as well as with augmentation of the bubble acceleration at each instant of time, independently of the internal vapor parameters for bubble. The theoretical results obtained were agreeable with the previous theoretical data available with error ± 8.80 % % for non-dimensional time τ=1 and within ± 5.4 % for non-dimensional time τ=10.

تم تطوير علاقة للتنبأ بمعامل الاعاقة في اجراء نمو فقاعة في بيئة متعلقة بحمل حراري (سوائل منتظمة نقية محمصة ). تم التحقق من المعاملات غير البعدية السائدة او المسيطرة على الحركة وانتقال الحرارة ودراسة تأثير تغيير هذه العوامل على نمو وتكوين الفقاعة. معامل السحب ينخفض مع الزمن لمختلف التعجيلات , بالاضافة الى ذلك فان تعزيز تعجيل الفقاعة لكل زمن لحظي يكون بشكل مستقل لمعاملات البخار الداخلية للفقاعة. النَتائِج النظرية كَانتْ متوافقة مع البيانات السابقةِ النظريةِ المتوفرةِ بنسبة خطأ± 8.80 % للمعامل 1 τ= و ± 5.4 % للمعامل τ=10.

Abstract

Background: Sella turcica is a saddle-like structure based on the roof of the sphenoid bone and has an importantrole in orthodontic diagnosis and treatment planning. The aims of the study were to assess sella shape and size in anadolescent Iraqi sample in different skeletal classes and to verify the possibility of clinical application of sella turcicain skeletal maturity estimation.Materials and Methods: The study sample composed of (140) Iraqi adolescent subjects aged 10-16 years (91 females,49 males); every subject had true lateral cephalometric radiograph. The sample was subjected to 2 classifications:the 1st included three skeletal classes according to ANB angle, and the 2nd included accelerative and decelerativegroups according to maturity indicators of cervical vertebrae seen radiographically. In each classification, sella sizewas measured using three linear measurements (S.length, S.depth, and S. diameter).Results: Most of sella turcica measurements were not different statistically among the skeletal classes, and thatspecific sella turcica linear measurements can not be obtained for each specific skeletal class throughout thepubertal period. Normal sella was the predominant over the other morphological aberrations in both classificationsystems, while these morphologies occurred more frequently in class II and III. Sella depth and diameter weresignificantly higher in the decelerative than accelerative group, while non significant difference was foundconcerning sella shapes between the two groups.Conclusions: It was concluded that Sella depth and sella diameter measurements can be utilized clinically forpubertal growth phase determination, while sella morphology can not be diagnostic for the accelerative anddecelerative pubertal growth phases

Abstract

Background: Fifteen percent of small for gestational age are small as a result of fetal growth restriction, which could be due to maternal, placental or fetal factors. It is an important clinical problem associated with increase perinatal mortality and morbidity. Leptin is a protein that produced by many tissues including the placenta (syncytiotropholoast). Dysregulation of leptin metabolism may be implicated in preeclampsia and IUGR pathogenesis. Aim of the study: To study the trend of leptin level alteration in maternal serum and cord blood in pregnancies complicated by fetal growth restriction and its relation with fetal outcome. Methods: An Analytic, cross- sectional study conducted in Al-Elwyia Maternity Teaching Hospital and Alkindy College of Medicine, from October 2009 to June 2010. Sixty seven pregnant women were included and they were divided into two groups: The first group (A) included 34 pregnant women with Intrauterine growth restricted fetuses with and without maternal diseases and the second group (B), included 33 pregnant women with normal pregnancies. Samples from maternal blood and umbilical cord blood were obtained at the time of delivery and leptin level was measured by Enzyme linked immunesorbant assey (ELISA) test. Results:Umbilical cord leptin level was significantly lower in group A (medain1ng/ml) compared with group B (median10.2ng/ml); P<0.001, and maternal serum leptin was also significantly lower in group A (median19.8ng/ml) compared to control group B (median31.8ng/ml), P 0.042. Newborn weight for age (Z score) and maternal body mass index were the most important and the only statistically significant determinants of cord blood leptin, while only maternal body mass index had a strong and statistically significant positive association with maternal serum leptin. In group A, there was a linear correlation between cord blood leptin and placental weight, P<0.001, and a linear correlation between Apgar score at 5minutes and cord blood leptin level, P<0.001.Conclusion: Women who had growth restricted fetuses had significantly lowered umbilical cord leptin level and maternal serum leptin level than women who had normal fetuses and the outcome of such fetuses could be related to leptin level. Key words: Intrauterine growth restriction, cord blood leptin, maternal serum leptin

Abstract

Background: The nail organ has an important functional and aesthetic importance. Nail Growth Rate (NGR) has attracted the attention of many investigators not only due to the importance of the nail apparatus but also as a tool to reflect health.Objective: To study the effects of smoking and age on nail growth.Patients and methods:The study was conducted at the Department of Physiology and the Department of Dermatology, College of Medicine, University of Baghdad during the period from January 2011 to May 2011. Nail growth measurement was performed by etching a T – mark on the nail plate of the right and the left thumbs with a wide bore needle. The vertical distance between the point of meeting of the T and the proximal nail fold was measured using (vernier). A second measurement was performed one month later. The difference between the 2 readings was divided by the number of days between the readings to give the NGR.Results:The NGR was measured in a total of 106 subjects. The subjects were divided into 3 groups:Group1 (Smoker male subjects): 23 subjects were included in this group. Their ages ranged between 20 and 59 years with a mean of 35.87 +11.72 years. Group 2 (Non-smoker male subjects): 34 subjects were included. Their ages ranged between 13 and 52 years with a mean of 31.76 + 10.16 years.Group 3 (Non-smoker female subjects): 49 subjects were included. Their ages ranged between 8 and 58 years with a mean of 27.49 +11.66 years. NGR measurement in:Group 1:The mean growth rate in the right thumb was 95.4 + 28.8 microns/day, and for the left thumb was 96 + 34 microns/day. Group 2:The NGR was 105.6 + 34.35, and 103.4 + 34.24 microns /day, for the right thumb and the left thumb respectively. . Group 3: The NGR was 100 .5 + 33.52 microns/day for the right thumb and 101.6 + 31.77 microns /day for the left thumb. Conclusion: Age was inversely correlated with nail growth in right and left thumbs in all groups. The duration of smoking and number of cigarettes was inversely related to nail growth, but it did not reach statistical significance. Keywords: Nail growth rate, smoking, age

Abstract

The present study tried to verify the most familiar method to orthodontist forpubertal stage estimation which is very important in orthodontic diagnosis and plan byusing Hand – Wrist radiographs and Orthopantomography (OPG). The sample of thisstudy has been selected from patients who were attending the Orthodontic departmentand Pedodontic and Preventive Dentistry department at the College of Dentistry –Baghdad University. Before starting the study a legal approval was obtained and theobjective of the study was explained to the parents of each participant. The sampleconsisted of 90 subjects (45 females and 45 males), of certain criteria, between 10 and16 years of age. The subjects of the sample were of Iraqi Arab origin; the radiographswere interpreted by specialist radiologist. Developmental stage of mandibular left 2ndmolar show a higher correlation with skeletal maturation stage of hand and wristbones (r=0.9) than the canine (r=0.7) for both males and females and can beconsidered as reliable indicator for maturational stage of individual. The skeletal ageis matched the chronological age at the pubertal growth spurt approximately 12 yearsfor females and 14 years for males, and then the sample had a tendency towardsadvanced maturation with mean skeletal age of the participating subjects being greaterthan the chronological age at the maturity stages. Developmental stage of mandibularleft 2nd molar might be considered as reliable indicator for maturational stage ofindividual, For the sample of this study, the skeletal age is matched the chronologicalage at the pubertal growth spurt approximately 12 years for females and 14 years formales.
