Children\u27s Reports of Child-Rearing Practices: A Preliminary Study

We present in this issue of The Cairo Papers a broad spectrum of articles dealing with the children of Egypt and their families; each article has a research base in the real world of childhood and each in its own way sug­gests trends for further work in both research and applied areas in child de­velopment. Ciaccio\u27s paper consists of an integrated set of recommendations based on action-oriented research sponsored by UNICEF- it is clear from a reading of his paper that the International Year of The Child is not simply another \u27UN year\u27 but rather a point of departure from which improved, increased and con­tinuing services for children will begin. Indeed, the second paper by Saleh and Moubarek take up Ciaccio\u27s challenge by showing how they have begun to re­build the school system of a Cairene sluni area, Bulaq. Their work has already served as a model for educational and social welfare improvement in several developing countries. Dr. Claire Fahim, eminent Egyptian Chil d Psychiatrist and long-time advocate of children\u27s rights in the Arab World, gives us an in­side view of the operations of a clinic for children which services over 124 schools in the West Cairo district; her successful use of the \u27team approach\u27 to child psychiatric problems is unique in Egypt. Fahmy\u27s paper concerning \u27emergent consciousness\u27 in a group of young women in the upper Egyptian village of Akhmim is a unique and fascinating doc­umentary of the socialization process_ of both males and females in a society undergoing rapid social change. Her perceptive use of in-depth interviews gives the reader an intimate view of family life paralleled perhaps only by Harrmed Arrmar\u27s Growing Up In An Egyptian Village (1954). Waines\u27 paper, a report of a pilot study she completed in 1978, actually is the first in a series of studies she is conducting on the mental health status of Egyptian children. She very clearly outlines the major clinical and research parameters involved and cogently argu es for more empirical data to guide future planning in the mental health field. The last paper in this issue, El-Mofty\u27s Children\u27s Reports of Child Rearing Practices, offers readers a most unusual and very refreshing view of socialization techniques as seen through the eyes of the children themselves. She presents data on sex and social class differences, some of which are clearly divergent from patterns found in the West. In sum, most of the articles in this volume represent work that is still in progress, work that will continue long after the celebration of the International Year of the Child. The underlying spirit of all the work however, is the recognition that the understanding and well-being of all children is closely linked with economic stability and world peace.https://fount.aucegypt.edu/faculty_book_chapters/1824/thumbnail.jp

Histopathologic risk factors in oral and oropharyngeal squamous cell carcinoma variants: an update with special reference to HPV-related carcinomas

Accurate identification of the microscopic risk factors of oral and oropharyngeal (OP) squamous cell carcinomas (SCC) and their morphologic variants is of at most importance, as these generally determine treatment modalities, prognosis and overall patient outcome. The great majority of oral and oropharyngeal squamous cell carcinomas are microscopically described as kerartinizing squamous cell carcinoma (KSCC). They bear certain resemblance to keratinizing stratified squamous epithelium. Tobacco habits and excessive consumption of alcoholic beverages have been considered to be the main etiologic agents in these carcinomas. The tumors occurred in older patients more commonly affected the oral tongue and floor of the mouth with well established morphologic risk factors including tumor grade, pattern of invasion and perineural involvement. Within the last 30 years however, the advent and expanding prevalence of high risk human papillomavirus (HPV) as an important etiologic agent for head and neck squamous cell carcinoma, particularly in the OP, has resulted in a significant change in the established morphologic criteria for risk assessment. The majority of HPV relate carcinomas of the OP are nonkeratinizing squamous cell carcinoma (NKSCC). These tumors are found to be more responsive to treatment with a favorable patient outcome and good prognosis. Consequently, alterations in treat - ment protocols aimed at de-escalation are currently being evaluated. More recently, other morphologic variants that are HPV positive are reported with increasing frequency in the OP and other head and neck sites. As a result, several clinical and pathologic questions have emerged. Importantly, whether the virus is biologically active in these tumors and involved in their pathogenesis, and second, what are the clinical implications with regard to patient management and outcome in the HPV-related variants. Examples of HPV-related squamous cell carcinoma variants that will be addressed here are: basaloid squamous cell carcinoma (BSCC), undifferentiated carcinoma (UCa), papillary squamous carcinoma (PSCC) and small cell carcinoma. Some studies have suggested favorable prognosis in some variants, analogous to that of the (NKSCC), while others showed poorer outcome. So far the number of studies on this subject is limited and the number of cases evaluated in each investigation is few. Because of that, it is prudent at this stage, not to alter management protocols as a result of identification of HPV in these variants and to await additional information

Metastasis occurring eleven years after diagnosis of human papilloma virus-related oropharyngeal squamous cell carcinoma

Human papilloma virus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) is associated with a favourable prognosis, although approximately 20–25% of patients ultimately develop recurrent cancer. Most disease recurrence events appear within 3 years; however, long-term follow-up of reported studies are limited, and the risk of late recurrence is unknown. We present a case report of a patient who developed distant metastases of HPV-related SCC 11 years after initial diagnosis and treatment of HPV-related OPSCC. Late disease recurrence may occur after initial diagnosis of HPV-related OPSCC. This observation has implications on the appropriate duration of follow-up and surveillance of these patients

Volumetric Soft Tissue Changes After Using Injectable Platelet-Rich Fibrin (I-PRF) Versus Subepithelial Connective Tissue Graft in Interdental Papillae Defects: A Randomized Controlled Clinical Study

Background: Lost interdental papillae in the esthetic region are of great concern from the esthetic and functional point of view. We elicit a clinical study of papillary reconstruction in this article using injectable platelet-rich fibrin (I-PRF) as a nonsurgical procedure and compare its results to those of the subepithelial connective tissue graft (SECTG), being considered the gold standard method used to reconstruct interdental papillae. Methods: Twenty-four patients seeking treatment for black triangles were randomized into two groups: group A patients were treated with the SECTG technique, and group B patients were treated with I-PRF. Four injections were given at each papilla site at baseline, two-, four-, and six-week intervals to ensure optimal esthetics. Pain, clinical, and volumetric assessments were done. Volumetric assessment was completed through intraoral scanning of the papilla site at baseline and after six months, after which the results were obtained by superimposition of both scans. Results: Group A (5.08 ±2.15) had a significantly higher mean pain score value than group B (1.17 ±0.94) (p < 0.001). Group B (0.31 ±0.21) had a higher mean value of volumetric changes at the interdental papillae than group A (0.25 ±0.17), yet the difference was not significant (p = 0.517). Conclusion: Injectable platelet-rich fibrin gave comparable results to SECTG in Nordland Class I defects only, provided that the injection protocol was once every 15 days for a two-month period. Patients treated with I-PRF were more satisfied with the procedure and the results than patients who were treated with SECTG

HPV-Related Nonkeratinizing Squamous Cell Carcinoma of the Oropharynx: Utility of Microscopic Features in Predicting Patient Outcome

Human papilloma virus (HPV) is an etiologic agent in a subset of oropharyngeal squamous cell carcinomas (SCCs). The aim of this study was to sub-classify SCC of the oropharynx based upon histologic features into nonkeratinizing (NK) SCC, keratinizing (K) SCC, and hybrid SCC, and determine the frequency of HPV and patient survival in each group. Patients with oropharyngeal SCC with a minimum of 2 years of clinical follow-up were identified from radiation oncology databases from 1997 to 2004. All patients received either up front surgery with postoperative radiation or definitive radiation based therapy. In situ hybridization (ISH) for high-risk HPV subtypes and immunohistochemistry for p16, a protein frequently up-regulated in HPV-associated carcinomas, were performed. Overall and disease-specific survival were assessed. Of 118 cases, 46.6% were NK SCC, 24.6% K SCC and 28.8% hybrid SCC. NK SCC occurred in slightly younger patients that were more often male. It more frequently presented with lymph node metastases and was surgically resected compared to K SCC. NK SCC was significantly more likely to be HPV and p16 positive than KSCC (P < 0.001) and to have better overall and disease-specific survival (P = 0.0002; P = 0.0142, respectively). Hybrid SCC was also more likely than K SCC to be HPV and p16 positive (P = 0.003; P = 0.002, respectively) and to have better overall survival (P = 0.0105). Sub-classification of oropharyngeal SCC by histologic type provides useful clinical information. NK SCC histology strongly predicts HPV-association and better patient survival compared to K SCC. Hybrid SCC appears to have an intermediate frequency of HPV-association and patient survival

A New Combination Formula for Treatment of Fungal Keratitis: An Experimental Study

Objective. To formulate and evaluate slow release ketoconazole and ketorolac to treat fungal keratitis and associated inflammation. Methods. Experimental study with the following outcome measures. Pharmaceutical Evaluation. Mucoadhesive gels containing ketoconazole and ketorolac were used. Microbiological in vitro evaluation was performed using cup method. In vivo evaluation was performed on 24 rabbits divided into 2 groups, 12 rabbits each, group A (fast release formula; 6 times daily) and group B (slow release formula; 3 times daily). Each group was divided into two subgroups (6 rabbits each). Both eyes of rabbits were inoculated with Candida albicans. The left eye of all rabbits received the combination formulae. The right eye for one subgroup received ketoconazole as control 1 while the other subgroup received placebo as control 2. Clinical follow-up was done and, finally, the corneas were used for microbiological and pathological evaluation. Results. Gels containing high polymer concentration showed both high viscosity and mucoadhesion properties with slower drug release. The infected eyes treated with slow release formula containing both drugs showed better curing of the cornea and pathologically less inflammation than eyes treated with fast release formula. Conclusion. Slow release formula containing ketoconazole and ketorolac showed higher activity than fast release formula against fungal keratitis and associated inflammation

Influence of Different Decontamination Approaches on Bone Substitute Adhesion to Peri-Implantitis Affected Implant Surfaces: An SEM Proof of Principle Study

Background: During healing, clot blended graft materials may retract away from implant surfaces creating microgaps that compromise re-osseointegration. The present study aimed to evaluate different surface decontamination materials’ effect on adhesion of the graft materials to peri-implantitis affected parts, a factor that can resist clot blended graft retraction improving re-osseointegration. Methods: Eighteen peri-implantitis affected implants diagnosed as hopeless and designated for removal contributed in this prospective, masked trial. Samples were randomly distributed into three groups, each of six implants. Group one (G1) was coated with hydroxyapatite of a micro particle size of 250 to 1000 µm after saline surface decontamination for two minutes. Group two (G2) peri-implantitis affected parts were treated with the graft material following two minutes of chlorhexidine gluconate 0.12% (CHX) surface treatment. Group three (G3) implants were coated with the graft material after citric acid (CA) (pH = 1) surface conditioning for two minutes. Implants in all groups were agitated in phosphate-buffered saline (PBS) by using an automatic tissue processor agitator for three minutes. Implants were prepared for surface scanning evaluation. Results: Scanning electron microscopy (SEM) observation of G1 saline treated control implants were devoid of bone particles adherent to peri-implantitis affected surfaces. The surface area covered by grafted particles in G2 was statistically higher than that of G1 (P&lt;0.01). Group three (CA-treated) showed nearly complete coverage of peri-implantitis affected parts by the graft material covering 88.8% of examined surface areas which was statistically higher than that of G2 (P&lt;0.05). Conclusion: Citric acid implant surface conditioning could improve implant re-osseointegration through enhancement of the graft adhesion to the implant surface. Smear layer barrier effect seemed to be the most important factor that compromised graft adhesion to preri-implantitis affected parts of the implant surfaces

New tumour entities in the 4th edition of the World Health Organization Classification of Head and Neck tumours: odontogenic and maxillofacial bone tumours.

The latest (4th) edition of the World Health Organization Classification of Head and Neck tumours has recently been published with a number of significant changes across all tumour sites. In particular, there has been a major attempt to simplify classifications and to use defining criteria which can be used globally in all situations, avoiding wherever possible the use of complex molecular techniques which may not be affordable or widely available. This review summarises the changes in Chapter 8: Odontogenic and maxillofacial bone lesions. The most significant change is the re-introduction of the classification of the odontogenic cysts, restoring this books status as the only text which classifies and defines the full range of lesions of the odontogenic tissues. The consensus group considered carefully the terminology of lesions and were concerned to ensure that the names used properly reflected the best evidence regarding the true nature of specific entities. For this reason, this new edition restores the odontogenic keratocyst and calcifying odontogenic cyst to the classification of odontogenic cysts and rejects the previous terminology (keratocystic odontogenic tumour and calcifying cystic odontogenic tumour) which were intended to suggest that they are true neoplasms. New entities which have been introduced include the sclerosing odontogenic carcinoma and primordial odontogenic tumour. In addition, some previously poorly defined lesions have been removed, including the ameloblastic fibrodentinoma, ameloblastic fibro-odontoma, which are probably developing odontomas, and the odontoameloblastoma, which is not regarded as an entity. Finally, the terminology "cemento" has been restored to cemento-ossifying fibroma and cemento-osseous dysplasias, to properly reflect that they are of odontogenic origin and are found in the tooth-bearing areas of the jaws
