Abstract

Aims: To determine cephalometric standards for Iraqi adults using Holdaway soft tissue analysis. Materials and Methods: The sample comprised 60 individual (31 males and 29 females), aged 18–23years. Ten linear and tow angular parameters were measured on lateral cephalometric radiographs, using the definitions provided by Holdaway. For each variable mean and SD were calculated, in additionindependent samples t– test was performed to detect sexual dimorphism. Results: Some differences were determined when the measurement obtained for Iraqi sample were compared to Holdaway norms.Iraqi adults showed a more obtuse H angle, less nose prominence, more upper lip strain, more skeletal convexity, and greater soft tissue chin thickness. In addition, a comparison between males and femalesrevealed a significant sexual dimorphism for upper lip sulcus depth, upper lip thickness, basic upper lip thickness, and soft tissue chin thickness. Conclusions: soft tissue cephalometric norms are specific foreach ethnic group. The normative data for Iraqi population should be used as a guide for diagnosis and planning of orthodontic treatment

Abstract

Background: Soft tissue impingement and lip form have often been overlooked in previous epidemiological surveys.Materials and Methods: About seven thousand 13 year olds with no history of orthodontic treatment were selected from six governorates (Baghdad the capital, Ninevah, Basrah, Diyala, Anbar and Najaf). An intra-oral clinical examination was used to assess traumatic overbite causing soft tissue impingement and the lip form of each student.Results: Soft tissue impingement was found in 2.7% (2.5% palatally and 0.2% labially). Normal lip form was found in 80.7%, contracting lip form in 14.7% and lip trap in 4.6% of the sample. All the previous were non-significantly related to gender and residency.Conclusion: Iraqi children present a much mre favorable lip form than Western children

Abstract

Aims: To reveal the possible soft tissue difference in the upper and lower lip heights, separations and coverage of lower lip to upper incisors in different Angle’s classes of malocclusion, to determine any difference in the mean between males and females for each variable and to find any correlation among the variables. Materials and Methods: Nightly nigh students (52 males, 47 females), 20–23 years of age that was randomly selected from the college of dentistry, University of Mosul.The overall sample was classified depending on Angle’s classification of malocclusion into four groups (Class I, II.1, II.2 and III). For each group, four facial soft tissue variables were measured directly using electronic digital viernier caliper. Results: A major findings that emerged from the research is that the Class I subjects possessed higher values of upper lip length followed by Class II then Class III, this difference is significant between Class I,III and II,III and non significant between I,II. Where as Class III subjects possessed non significant higher values of lower lip length followed by Class II then Class I. The lip separation value is non significantly higher in Class II subjects followed by Class III then Class I. While Class III subjects possessed non significant higher values of lower lip to incisor superior followed Class I then Class II. Conclusions: For each specific Angle’s class of malocclusion, a specific facial soft tissue parameters. The upper lip length is greater in Class I subjects. Class III subjects have the greater lower lip length. The inter–labial gap is larger in Class II subjects.While the coverage of the lower lip to incisor superior is greater in Class III subjects. Most of the variables are higher in males than females. Complex correlations among the studied variables are found that varied between weak to high positive or negative with varying degree of significance.

Abstract

Background: The neurohormone namely melatonin is secreted by the pineal body in brain. It could reach all the bodily tissues and cells; affecting their function, depending on its biological level. Thymus gland is well known to be the main central immunity director, and its wellness is rather proportional to melatonin level.Aims: This work was done to study the histopathological effect of exogenous melatonin on thymic connective tissue bulk.Materials and Methods: Dietary melatonin was supplied to adult rats, for successive 30 days. Rats were divided 6 groups. Group 1 was the control, group I was the control. Group II, III, IV, V and VI were supplied with a daily measured quantity of melatonin as 125, 250, 500, and 1000 µm/kg body wt, respectively. After the last day of treatment all animals were killed then the left thymic lobe was removed under anesthesia for histopathological study.Results: No noteworthy effect of melatonin was seen on the thymic connective tissue on its normal doses, whilst it had significant effect on the connective tissue bulk with its large doses.Conclusions: The treatment of dietary melatonin had no important effects on the rat thymic connected tissues, on its little doses, but it has considerable effects when administrated in large doses.

The technique provides tissue of similar texture and color tothe defect to be covered and has the added advantage of minimal donor site morbidity.This study aimed to assess the results & complications in the correction of post burn scalpalopecia using a tissue expansion, prevention of implant extrusion, lower the infection rate intissue expansion and expander selection.Forty patients with scalp burn alopecia treated with tissue expansion of the scalp, wereincluded in this prospective study in Sulaimania hospital of burn and reconstructive surgery fromFebruary 2002 to September 2009 with age groups ranging from (4-30) years with an averageof 15.5 years. Twenty three patients were females.The time period between burn injury and reconstruction ranged between (4-25) years, theirscalp defects ranging between (5x10cm -13x25cm). We were able to completely reconstruct77.5% of the total patients with single or multiple sessions of expansions. The remaining 22.5%patients have benefited from reduction in the percentage of alopecia and recreation of anteriorhair line to camouflage their defects. Major complications occurred in 6 cases(15%), in whichthe expansion process interrupted with removal of the expander.In conclusion, It is not always possible to measure the absolute efficacy of a surgical techniqueor determine a general guideline its indication of the tissue expansion procedure althoughafflicted with a broad range of possible complications, the tissue expansion procedure remains avaluable and reliable technique for the reconstruction of post burn alopecia of the scalp.

Abstract

Background Over the past decade there has been a growing awareness of, and interest in, the trace element concentration differences between normal and diseased tissues. Significant changes in tissue concentrations of Zinc (Zn) and Copper (Cu) have been previously reported in inflammation and cancer of certain human tissues.Aim:(1)To correlate between Zn and Cu concentrations and the histological picture of normal and certain inflamed human tissues, namely the gall bladder (GB) the vermiform appendix (VA), visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT). (2) to detect whether there is a difference in the above-mentioned parameters between VAT and SAT. (3) to obtain recordings for trace element levels in human tissues.Methods: Diseased GB (10), VA (10), VAT (10) near these organs and SAT (10) were removed by surgery. Tissues from these organs were then processed for histopathology and analyzed for trace elements concentration by Atomic Absorption Flame-Emission Spectrophotometer.Results: Zn concentration was high in VAT (0.410 μg/g ± 0.181), GB (0.478 μg/g ±0.531) and VA (0.419 μg/g ±0.123) when compared to its level in SAT (0.1329 μg/g ± 0.0129) and the difference was significant (<0.007,<0.056 and <0.000 respectively).Cu concentration was high in VAT (0.640 μg/g ± 0.150) and GB (0.919 μg/g ± 0.564) when compared to SAT (0.3893 μg/g ± 0.0130) and the difference was significant (<0.005 and <0.011 respectively). Cu concentration in the VA was low (0.2055 μg/g ±0.0654) and significantly different from all the other tissues (VA vs VAT <0.000, VA vs GB <0.002 and VA vs SAT <0.000).The histology findings were typical of chronic inflammatory reactions in the GB and of acute inflammation in the VA.Conclusions: The increase in tissue concentrations of Zn in VAT, GB & VA is due to inflammation.The high Cu level in chronically inflamed GB and neighboring VAT is due to the increased need for this element during inflammation.Our results, together with findings reported by others, allow us to think of using trace elements, namely Zn and Cu, as tools for diagnosis and treatment in appropriate conditions.Key words: Tissue trace elements – Zinc – Copper
