Epidermolysis bullosa (EB) is an acquired disease or inherited as either autosomal dominant or recessive with an incidence of 1/50,000. The prominent clinical characteristic of the disease is the development of bullae or vesicles in mucosa or skin in response to minor trauma. A female patient with a dystrophic type of EB had been put in a maintenance regimen after completion of the initial phase of periodontal therapy and followed for 7 years. The purpose of this report is to document acellular dermal matrix allograft application to increase the width of the attached gingiva in this patient experiencing difficulty in chewing and performing plaque control due to the dramatic loss of attached gingiva after 7 years of supportive periodontal therapy. Under local anaesthesia and antibiotic coverage, the acellular dermal matrix allograft was applied in the anterior region of the upper jaw in order to increase the width of attached gingiva, thereby improving patient comfort. The healing was uneventful and a significant gain in attached gingiva dimensions was observed 9 months after the periodontal surgery. The procedure avoided a second surgical site, provided satisfactory results from an aesthetic point of view, and improved patient comfort. Acellular dermal matrix allograft may be regarded as an alternative in the treatment of EB cases to increase the width of attached gingiva and facilitate maintenance of the dentition.

The purpose of this study was to evaluate the effect of race, age, and gender on Commision Internationale de l'Eclairage Lab color space (CIELAB) values of attached gingival colors. The color coordinates of an optimal proposed attached gingival shade guide were also determined. Participants (n = 120) were recruited to fulfill the following stratification of five age groups: 18-29, 30-39, 40-49, 50-59, and 60-85, with four racial categories (white, black, Asian, and others) and balanced for gender. Reflectance measurements of participants' attached gingiva were made using a spectroradiometer and Xenon arc lamp with a 45/0 optical configuration. A stepwise discriminant analysis was carried out to identify gingival color contribution from race, age, and gender. A hierarchical clustering analysis was used to identify color groups that clustered together. The coverage error of the proposed shade guide was calculated to the original gingival color. The stepwise discriminant analysis showed a statistically significant difference in gingival color contribution from the factors evaluated. Significant influence was found for the race/gender factors (p L*a*b* as follows: (1 = 51.0 ± 4.2, 27.7 ± 4.7, 18.3 ± 3.2), (2 = 61.4 ± 4.5, 24.3 ± 4.3, 17.6 ± 2.3), and (3 = 36.1 ± 4.1, 21 ± 4.9, 16 ± 5.2). The coverage errors to the following racial categories were: Asian (ΔE = 6.0 ± 4.8), black (ΔE = 6.7 ± 3.9), others (ΔE = 5.8 ± 2.9), and white (ΔE = 4.6 ± 2.7). The study showed that L*a*b* was significantly affected by race and gender. Clustering analysis was able to identify clusters in 120 participants for three gingival tones. © 2014 by the American College of Prosthodontists.

Removable dentures with different denture teeth may provide different performance and resistance in implant and gingival situations, or anterior and posterior applications. Two situations of removable dentures were investigated: gingiva (flexible) and implant (rigid) bearing. For simulating the gingiva/jaw situation, the dentures were supported with flexible lining material. For the implant situation, implants (d = 4.1 mm) were screwed into polymethylenmethacrylate (PMMA) resin. Two commercial (Vita-Physiodens MRP, SR Vivodent/Orthotyp DCL) and two experimental materials (EXP1, EXP2) were investigated in anterior (A) and posterior (P) tooth locations. Chewing simulation was performed, and failures were analyzed (microscopy, SEM). Fracture strength of surviving dentures was determined. Only EXP1 revealed failures during chewing simulation. Failures varied between anterior and posterior locations, and between implant (P:4x; A:7x) or gingiva (P:1x; A:2x) situations. Kaplan-Meier log-rank test revealed significant differences for implant situations (p 0.093). Fracture testing in the implant situation provided significantly highest values for EXP2 (1476.4 ± 532.2 N) in posterior location, and for DCL (1575.4 ± 264.4 N) and EXP2 (1797.0 ± 604.2 N) in anterior location. For gingival bearing, significantly highest values were found for DCL/P (2148.3 ± 836.3 N), and significantly lowest results for EXP1/A (308.2 ± 115.6 N). For EXP1 + EXP2 + Vita/P and for EXP1/A no significant differences were found between implant- or gingiva-supported situations. Anterior and posterior teeth showed different material-dependent in vitro performance, further influenced by implant/gingiva bearing. While an implant in anterior application increased fracture strength of two materials, it decreased fracture values of 3/4 of the materials in posterior application. Survival of denture teeth may be influenced by material, oral position, and bearing

This narrative review aims to outline the concepts on the significance of the width of attached gingiva around teeth and implants to enable the clinician to decide on the need for gingival augmentation in different clinical scenarios. An electronic search was done on PUBMED & Cochrane Database using the keywords from 1972 to November 2009. A manual hand search was also done in Journal of Periodontology and Journals of Clinical Periodontology for relevant articles under this topic. Any relevant paper from the references was hand searched. A total of 1167 references were obtained, 103 full text papers was retrieved of which 59 articles was selected for this review. The width of attached gingiva is not significant to maintain periodontal health in the presence of adequate oral hygiene. However, thin gingival tissues around teeth with restorations or undergoing labial orthodontic tooth movement may be more susceptible to recession. The functional need for attached gingiva around implants has not been established but its aesthetic value has been widely accepted. Copyright 2010 Elsevier Ltd. All rights reserved.

Procuring a free gingival autograft for the purpose of gingival augmentation has been advocated in areas of inadequate width of attached gingiva that result in gingival recession and/or accumulation of local factors. As obtaining the graft from the palatal donor site with conventional scalpel techniques can result in problems such as prolonged bleeding, increased surgical time and patient discomfort, alternative methods have been advocated to procure such grafts using lasers and electrocautery. This case report elaborates, a free gingival graft harvested for the purpose of increasing the width of attached gingiva using electrocautery principles. The parameters assessed included the extent of patient reported discomfort at the donor site and clinical gain of keratinized and attached gingival width. PMID:25386540

The attached gingiva is a desirable anatomical element for the maintenance of gingival health. The free gingival graft (FGG) and the modified apically repositioned flap (MARF) are predictable surgical techniques often employed to increase the zone of attached gingiva. This randomized study compared the FGG and the MARF in increasing the zone of attached gingiva in contralateral sides of 15 patients 1 year posttreatment. There was an increase in keratinized tissue and attached gingiva in both groups. Gingival recession did not significantly change between pre- and posttreatment levels in either group. The MARF surgical time was approximately half as long as that of the FGG. The authors conclude that both techniques are viable; however, the main advantages of the MARF were decreased surgical time and less postoperative discomfort.

Gingival pigmentation is a common finding, may be of endogenous or exogenous origin, and can have diagnostic significance. Diffuse gingival pigmentation may be physiologic in nature or can be due to environmental factors, drugs, endocrine disorders, or genetic conditions. We present four cases of diffuse gingival pigmentation due to traditional gingival tattooing and review the literature on this practice. Four black females (aged 19 to 56 years) of West African origin (Mauritania and Senegal), representing three different ethnic groups (Fulani, Mandinka, and Soninke) presented with various chief complaints. All exhibited diffuse pigmentation of the maxillary vestibular gingiva extending to the second premolar areas, without any associated radiographic abnormalities. The color ranged from intense blue gray to light gray or grayish pink. One case was biopsied for histopathologic evaluation. Questioning revealed that the women had had one or more sessions of traditional gingival tattooing. In one case, the procedure was performed in a dental office. The color range appeared to depend on the time that elapsed since the last procedure. The biopsy exhibited dense fibrous connective tissue containing aggregates of foreign material consistent with a foreign body tattoo. Gingival tattooing, a cultural practice prevalent in certain African ethnic groups, results in diffuse pigmentation. Outside of Africa, it may be misinterpreted as racial pigmentation or pose a diagnostic puzzle. The color and distribution pattern of diffuse gingival pigmentation often are quite suggestive, and the clinical diagnosis should be confirmed by patient history. In selected cases, biopsy may be necessary to exclude other diagnostic considerations.

To compare the initial failure rate (≤4 months) for extra-alveolar mandibular buccal shelf (MBS) miniscrews placed in movable mucosa (MM) or attached gingiva (AG). A total of 1680 consecutive stainless steel (SS) 2 × 12-mm MBS miniscrews were placed in 840 patients (405 males and 435 females; mean age, 16 ± 5 years). All screws were placed lateral to the alveolar process and buccal to the lower first and second molar roots. The screw heads were at least 5 mm superior to the soft tissue. Loads from 8 oz-14 oz (227 g-397 g, 231-405 cN) were used to retract the mandibular buccal segments for at least 4 months. Overall, 121 miniscrews out of 1680 (7.2%) failed: 7.31% were in MM and 6.85% were in AG (statistically insignificant difference). Failures were unilateral in 89 patients and bilateral in 16. Left side (9.29%) failures was significantly greater (P placement in MM or AG. Failures were more common on the patient's left side and in younger adolescent patients. Having 16 patients with bilateral failures suggests that a small fraction of patients (1.9%) are predisposed to failure with this method.
Full Text Available Abstract Background Odontogenic tumors are lesions that are derived from remnants of the components of the developing tooth germ. The calcifying cystic odontogenic tumor or calcifying odontogenic cyst is a benign cystic neoplasm of odontogenic origin that is characterized by an ameloblastoma-like epithelium and ghost cells. Calcifying cystic odontogenic tumor may be centrally or peripherally located, and its ghost cells may exhibit calcification, as first described by Gorlin in 1962. Most peripheral calcifying cystic odontogenic tumors are located in the anterior gingiva of the mandible or maxilla. Case presentation Authors report a rare case of a peripheral calcifying cystic odontogenic tumor of the maxillary gingiva. A 39-year-old male patient presented with a fibrous mass on the attached buccal gingiva of the upper left cuspid teeth. It was 0.7-cm-diameter, painless and it was clinically diagnosed as a peripheral ossifying fibroma. After an excisional biopsy, the diagnosis was peripheric calcifying cystic odontogenic tumor. The patient was monitored for five years following the excision, and no recurrence was detected. Conclusions All biopsy material must be sent for histological examination. If the histological examination of gingival lesions with innocuous appearance is not performed, the frequency of peripheral calcifying cystic odontogenic tumor and other peripheral odontogenic tumors may be underestimated.

Full Text Available The indications to increase the width of keratinized gingiva have not been proven beyond doubt; however it becomes indispensable in certain clinical situations. Inspite of frequently encountered complications, palate is considered most preferred area to harvest the free gingival graft (FGG. This procedure aimed at investigating the potential of buccal marginal gingiva as a donor to augment keratinized gingiva. To the best of our knowledge, no such cases have been documented in the literature. FGG harvested from maxillary buccal marginal gingiva was used to augment gingiva in the mandibular anterior region for two patients. This not only improved plaque control but also resulted in acceptable esthetic results over 3 years. Furthermore, gingiva at donor sites gained its normal form and was in harmony with the neighboring teeth. It may be concluded that buccal marginal gingiva may provide a predictable substitute to other donor tissues to augment gingiva.

Full Text Available Hyperactivity of melanocytes is the reason for dark colour of gingiva, which is absolutely benign condition with only esthetic disadvantage, for people with gummy smilemostly. Depigmentation is a procedure of removing or reducing of gingival hyperpigmentation. The purpose of the research is to investigate the advantage of using Er:YAG laser than liquid nitrogen in case of gingival depigmentation. That’s why two alternative methods are used: laser ablation with an Er:YAG laser and cryosurgical procedure of tissue destruction by fast freezing with liquid nitrogen (-196º C.Laser assisted gingival depigmentation is a single step procedure, with fast healing process. There is difficult control of penetration and risk for excessive tissue destruction after prolonged freezing in the cryosurgical procedure.

Full Text Available A protocol to choose the graft diameter attachment point of each bundle has not yet been determined since they are usually dependent on a surgeon’s preference. Therefore, the influence of bundle diameters and attachment points on the kinematics of the knee joint needs to be quantitatively analyzed. A three-dimensional knee model was reconstructed with computed tomography images of a 26-year-old man. Based on the model, models of double bundle anterior cruciate ligament (ACL reconstruction were developed. The anterior tibial translations for the anterior drawer test and the internal tibial rotation for the pivot shift test were investigated according to variation of bundle diameters and attachment points. For the model in this study, the knee kinematics after the double bundle ACL reconstruction were dependent on the attachment point and not much influenced by the bundle diameter although larger sized anterior-medial bundles provided increased stability in the knee joint. Therefore, in the clinical setting, the bundle attachment point needs to be considered prior to the bundle diameter, and the current selection method of graft diameters for both bundles appears justified.

Full Text Available Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and anterior cruciate ligament avulsion fracture was not associated with posterior cruciate ligament injury, posterolateral corner injury, or tibial plateau fracture. This new combination of injuries provides better understanding of the mechanisms of ligamentous injuries of the knee and highlights the importance of meticulous assessment of these injuries for accurate diagnosis and subsequent management.

Abnormal deposition of melanin in gingiva can often occur. Complaints of "black gums" are common, and demand for depigmentation is usually made for esthetic reasons. A simple and effective cryosurgical technique to eliminate the pigmentation is the subject of this article. Twenty patients with dark gingiva were treated by direct application of liquid nitrogen with a cotton swab for 20 to 30 seconds. The treated gingiva appeared normal within 1 to 2 weeks after 1 or 2 cryosurgical treatments. The acceptance of the treatment was excellent. This was a simple, bloodless cryosurgery for the depigmentation of gingiva, requiring no local anesthesia or sophisticated equipment.
Full Text Available Rhabdomyosarcoma is a malignant skeletal muscle neoplasm. The tumor is much more common in children, and the most frequent site is head and neck region. Since this tumor is less frequent than other neoplasms in oral cavity, the clinicians sometimes ignore it, working the patients up. Rhabdomyosarcoma is a high-grade malignancy with poor prognosis. Considering the aggressive behavior and various clinical or histopathologic presentations of the tumor, early diagnosis has a significant impact on the treatment outcome and prognosis of the patients. We highlight the importance of combining the clinical, radiographic, and histopathologic examination to obtain a definitive diagnosis in sarcomas of the head and neck region, especially rhabdomyosarcoma. A case of rhabdomyosarcoma of the maxillary gingiva is presented in a 32-year-old woman in which the primary incisional biopsy was erroneously interpreted as an inflammatory process and consequently, the accurate diagnosis postponed for about 10 months.

Although studies support the clinical importance of the fibres from the horns of lateral meniscus (LM), few studies have investigated the detailed anatomy. This anatomic study was conducted to analyse the structural details of LM with special reference to (1) the attachment area of the fibres from the anterior and posterior horns and (2) the positional relationship between these fibres and the anterior cruciate ligament (ACL). A total of 24 cadaveric knees were used in the macroscopic investigation, and six knees were used in the histological investigation. Micro-computed tomography analysis was also performed to assess the anatomy of the posteriormost fibre from the posterior horn of LM. Based on the macroscopic investigations, the outer fibres from the anterior horn of LM extended to ACL and seemed to intermingle with ACL fibres. However, the histological investigations showed a distinct border between the fibres and ACL. The inner fibres from the anterior horn of LM attached to the lateral intercondylar tubercle serving as a lateral margin of ACL attachment. Fibres from the posterior horn of LM were separated into anterolateral and posteromedial crura which attached to the posterior aspect of the lateral and medial intercondylar tubercles, respectively. These two crura formed the posterior margin of the ACL attachment, except for the central part of ACL. The outer fibres from the anterior horn of LM adjoined ACL. The inner fibres from the anterior horn of LM and two crura from the posterior horn of LM formed the border of the attachment area of ACL. The distinctive fibre anatomy from LM could provide a surgical landmark during arthroscopic surgery.
Full Text Available Leiomyoma is a benign tumor originating from the smooth muscle. The most frequent site of appearance is uterine myometrium, gastrointestinal tract and skin. They are rare in oral cavity (0.065% due to the scarcity of smooth muscles. The most common sites of occurrence in oral cavity are tongue, lips, hard and soft palate and cheeks. Other less frequent locations are the floor of mouth and gingiva. We present a rare case of leiomyoma in a 20-year-old female patent, present since 6 years involving the gingiva between lower left canine and first premolar. Clinical and histopathological examination confirmed the diagnosis of leiomyoma.

Gingival melanin pigmentation occurs in people of all races. Although clinical melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly made by fair-skinned people with gingival melanin pigmentation. This problem is aggravated in patients with a "gummy smile" or excessive gingival display while smiling. Esthetic periodontal plastic surgery is especially successful in individuals with compromised esthetics. Three cases are reported here where gingival depigmentation was done using three different techniques: electrosurgery; scalpel surgery; and surgical abrasion. The clinical results of the three methods have been compared.

Full Text Available In severely protrusive patients, skeletal anchorage from miniscrew is often used to avoid anchorage loss with preferred miniscrew location near centre of resistance (Cres of posterior teeth. Biomechanical requirement for directing retraction force towards Cres of posterior teeth demands the insertion of miniscrew in loose mucosa, where risk of infection and failure increases. In addition, undesirable biomechanical side effects on anterior and posterior segments may be possible in all three planes, when continuous arch sliding mechanics are installed with miniscrew anchorage. This paper describes technique of molar-stabilizing power arm (MSPA for simultaneous intrusion and retraction of anteriors with miniscrew placement at attached gingiva between 1st molar and 2nd premolar. Advantages of this technique include (i the need of miniscrews placement in loose mucosa apically near the Cres of the posterior teeth is eliminated, (ii the risk of infection and miniscrew failure is lowered since the miniscrew is placed in attached gingiva rather than the loose mucosa, and (iii by adjusting vertical length or replacing MSPA, alteration of the retraction force vector is possible in all three planes; thus, need of removal and repositioning of the miniscrew (e.g., in correction of occlusal cant can be eliminated.

Pigmentation on gingiva can be physiologic or pathologic. Gingival pigmentation is present from birth in certain individuals. However, sudden occurrence of pigmentation suggests some systemic association. In the present case, a patient was referred by a physician for biopsy of the tissue along with gingival depigmentation. The depigmentation procedure was performed in both arches, and the biopsy specimen was sent for histopathologic examination. This case highlights the importance of biopsy of gingival pigmentation with a history of sudden occurrence. A biopsy is warranted to distinguish pathologic pigmentation from physiologic.
Reducing CD4+ Expression at Gingiva Exposed A.Actinomycetemcomitans using Curcuma Zedoaria Rosc., Zingiberaceae. Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans is a gram-negative bacteria associated withperiodontal disease. Positive expression of CD4+ is shown in gingivitis and periodontitis. The aim of this study was to determine the effect of curcuma zedoaria Rosc., volatile oil against CD4+ expression on gingiva exposed A. actinomycetemcomitans. The study was conducted on male Wistar rats aged 3 months that were exposed bacteria A. Actinomycetemcomitans. Treatment group as many as 5 rats were administered orally with curcuma zedoaria Rosc. volatile oil at dose of 30.6 μl/ml for 14 days and distilled water in control. A 100 μl bacteria were applied on the 7th to 14th day on the gingiva anterior mandibular. At the 15th day, rat was anesthetized then sacrificed. The mandibular gingiva anterior of the rat was taken as histological preparations for HE and immuno-histo chemical staining. CD4+ antibody (Santa Cruz Biotechnology, USA was used for immune staining. Histological preparations were observed under a light microscope.The results showed a strong positive CD4+ expression in the lamina propria and stratum basale of control group while a weak positive expression in lamina propria area of treatment group. From the experiment, it is concluded that theinduction of curcuma zedoaria Rosc. volatile oil may reduce gingivitis, indicated by the decrease in CD4+ expression.
Full Text Available Aim. To investigate the frequency of discoloration of gingiva in the presence of fixed dental restorations, regarding the type of alloy of which restorations were made, and to show histopathological changes of discolored gingiva. Methods. One hundred and eighty four patients of both sexes were examined. The average age of the examinees was 52. They were divided into four groups according to the alloys from which their restorations were made. Standardized history questionnaires and clinical examination procedures were developed for this study. In ten examinees, whose teeth were indicated for extraction and who had a discoloration of gingiva, the samples of tissue were taken from the discolored gingiva for histopathological examination. Results. Our results showed the presence of discolored gingiva in all four groups. It was most frequent in the examinees with fixed restorations made of Ni-Cr alloy (43,5% and less frequent in those with fixed dental restorations made of gold alloy (26,5%. Histopathological examination showed the presence of tissue foreign body granulomas with giant cells in which the metal particles were found, partially as small and partially as large particles. Conclusion. Results suggested that grayish discoloration of gingiva was present in all four groups of examinees. The highest number of examinees with discolored gingiva was in the group with restorations made of Ni-Cr alloy. Grayish discoloration of gingiva was a consequence of incorporation of metal particles into gingival tissue.

We have established a method to observe circulation in a small area of the human gingiva. Reflected light photo-plethysmographs (RLP) and transilluminated light photo-plethysmographs (TLP) were recorded from healthy gingiva in 2 young adults of twenties. A tungsten-lamp, connected to a stabilized power source, was used to illuminate the gingiva. The reflected or transilluminated light was collected using a fibre-optic bundle. A CdSe photo-conductive cell was used as the photo-detector. The ECG was recorded simultaneously. The results were as follows: 1) RLP and TLP were both synchronous with the heart beat and showed a dicrotic-notched wave form. 2) When the light-collecting fibre was 0.5 mm from the surface of the gingiva, the dicrotic notch with TLP was clearer than that with RLP. 3) When the light-collecting fibre was placed less than 0.5 mm from the gingival surface, clear dicrotic notches were seen in RLP. 4) When the surface of the gingiva was covered with white opaque paint to prevent transilluminated light, definite dicrotic notches were observed with RLP. 5) RLP was produced mainly by the pulsation of the gingival surface, and the pulsatile movement of the tooth had a little effect on RLP. 6) RLP was consisted from the light reflected from the surface of the gingiva and also from the light reflected after penetrating some distance in the gingival tissue.

Full Text Available White lesions of the oral cavity are not uncommon though majority of them are benign. This case report documents a rare case of idiopathic linear leukoplakia of gingiva with no apparent etiology. Initial examination revealed a non-scrapable linear white lesion on the marginal and papillary gingiva of upper right teeth region. Incisional biopsy was taken for pathologic evaluation. Patient was treated with routine oral hygiene procedures and excision of the lesions. The histopathological results demonstrated hyperparakeratinized/orthokeratinized hyperplastic oral epithelium with orthokeratin-filled clefts and with no dysplasia. Clinical results demonstrated no recurrence after electrosurgical intervention. This paper reports a rare case of idiopathic linear leukoplakia of gingiva which was non-dysplastic in nature. Electrosurgical treatment proved to be successful compared to surgical technique as there was no recurrence even after two years of follow-up.
Full Text Available Dental materials especially orthodontic elastics often get embedded in gingival tissues due to iatrogenic factors. If retained for a long time, inflammatory response starts as asymptomatic crestal bone loss and may progress to severe periodontal abscess. Unsupported orthodontic elastics used for diastema closure may result in exfoliation of teeth, while elastic separators may get embedded in interdental gingiva if banding is performed without removing it. These cases of negligence are detrimental for survival of affected teeth. This paper highlights a case of orthodontic elastic embedded in interproximal gingiva of a 23-year-old healthy female for 7 years after completion of fixed orthodontic treatment. Surprisingly, there was no clinical sign of inflammation around elastic band and it was removed easily without any local anaesthesia. However, mild crestal bone loss was observed on periapical radiograph. The gingiva healed completely after sub gingival debridement.

Cigarette smoking is currently considered as a risk factor for periodontal disease. Controversy exists as to whether the vasoconstrictive property of nicotine is one of the pathogenic mechanisms. To this end we tested the hypothesis that cigarette smoking is causing vasoconstriction in the healthy human gingiva. Gingival blood flow was continuously measured with laser Doppler flowmetry in healthy (n=13) casual consumers of tobacco. Simultaneously, recordings were made of skin blood flow in the forehead and the thumb as well as heart rate (HR) and blood pressure (BP). In another session infraorbital nerve block anaesthesia (INB) with 1.0 ml of Carbocain without vasoconstrictive additives was used to identify nervously mediated vascular responses to cigarette smoking (n=8). Cigarette smoking induced a modest hyperaemic response in the gingiva that was lower than the relative increases in BP and HR, and the calculated gingival vascular conductance decreased. In the forehead, flow responses were similar to those in the gingiva, while in the thumb a powerful vasoconstriction was observed. During the later part of the 10-min recovery period, BP and HR tended to decrease while blood flow in the gingiva and forehead remained high. INB potentiated the hyperaemic response to cigarette smoking in gingiva. The present results help to shed some light on the understanding of the vasoactive mechanisms induced by cigarette smoking, and to support the hypothesis that cigarette smoking causes nervously mediated vasoconstriction in the healthy human gingiva. However, the degree of vasoconstriction was far less than in the thumb skin, and in our subjects was overcome by the evoked rise in arterial perfusion pressure. As a consequence, gingival blood flow increased during smoking. It is speculated that small repeated vasoconstrictive attacks due to cigarette smoking may in the long run contribute to gingival vascular dysfunction and periodontal disease.

An adequate amount of keratinized gingival tissue that is under proper plaque control, is a fundamental requirement for periodontal health. When the teeth erupt uneventfully in the center of the alveolar ridge, an adequate amount of keratinized tissue will surround the erupted permanent tooth. Labially or buccally erupting teeth show reduced dimensions of the gingiva as abnormal eruption of permanent teeth restricts or eliminates the keratinized tissue between the erupting cusp and the deciduous tooth. A lack of attached gingiva poses a potential risk for gingival recession in labially or buccally erupted teeth due to the possibility of accumulation of plaque and/or traumatic tooth-brushing during subsequent orthodontic treatment. A good understanding between the orthodontist and periodontist along with proper management of periodontal tissues, can prevent these problems. Various surgical techniques can be employed to uncover impacted teeth. This paper discusses the validity of utilizing periodontal surgery to increase a band of keratinized tissue in a case of an impacted canine erupting from the alveolar mucosa. PMID:20379417

The aim of this study is to evaluate the capability of fractal analysis to discriminate the changes in the trabecular structure of interdental bone between individuals with healthy gingiva or moderate periodontitis using digital images. Two groups of patients were included according to the probing depth, bleeding on probing, and clinical attachment level. The first group (n = 50) consisted of individuals with healthy gingiva, whereas the other group consisted of patients with moderate periodontitis (n = 50). Periapical images obtained with a storage phosphor plate system during clinical examination were used for the fractal dimension (FD) calculations. Two rectangular regions of interest (ROIs) were placed at mandibular posterior interdental bone areas. The mean of the two ROIs was used to calculate mean FD by using the box-counting method. Student t test was used for the comparison of the FDs of the two groups (P = 0.05). The mean FD of patients with periodontitis was 0.83, whereas it was 1.02 for the patients with healthy gingiva. A significant difference was obtained in the mean FD values of healthy individuals and patients with moderate periodontitis (P periodontitis and therefore can be recommended for the diagnosis and monitoring of changes in trabecular architecture associated with periodontitis.

Full Text Available Incidence of anterior cruciate ligament (ACL rupture and its consequent reconstruction is on the rise. In contributing to the achievement of anatomic reconstruction this study seek to provide information regarding the position and variability of the tibial attachment sites, dimensions of femoral insertions and compare these measurements in males and females, and in right and left knees. Thirty one cadaveric knees (15 right and 16 left from 9 females and 7 males, mean age 77 years were dissected. Various ACL footprint dimensions were taken. The mean length and width of the tibial anteromedial (AM bundle footprint were 8.9 and 9.8 mm while that of the posterolateral (PL bundle were 9.3 and 8.0 mm respectively. The mean length and width of the tibial AM and PL bundles in males were 8.5 and 9.8 mm, and 9.1 and 8.3 mm while corresponding values in females were and 9.2 and 9.7 mm, and 9.4 and 7.8 mm respectively. Males had larger femoral footprints (P=0.020 and tibial plateau (P<0.001. No significant difference between the right and left knees were observed. The mean anatomical positions of the AM and PL bundles were 46.0% and 50.0% of the mediolateral diameter of the tibial plateau. The mean length and width of the ACL femoral insertion sites were 8.3 and 7.7 mm for the AM bundle and 7.8 and 6.9 mm for the PL bundle respectively. The smaller ACL attachment parameters in females could be a contributing factor to the higher incidence of ACL rupture in female athletes.

For this article all cases of suspected drug-induced discolouration of teeth and gingiva reported between 1.1.1989 and 31.5.1997 have been collected. As far as documented all discolourations were reversible and represented exclusively undesired but not serious adverse drug effects. In the literature such events are usually not mentioned. Thus, sense and intention of this work is to draw attention to certain adverse effects that are hitherto not well known.
Full Text Available Amit A Paryag,1 Reisha N Rafeek,1 Melissa S Mankee,2 Jenai Lowe1 1School of Dentistry, The University of the West Indies, Mount Hope, 2Tooth Haven Dental Studio, D'Abadie, Trinidad and Tobago Abstract: Gingival recession has a diverse etiology. The consequences may include gingivitis, periodontitis, and hypersensitivity. Whereas the management can include surgical treatment options, sometimes a more conservative, yet still esthetic approach may be required. The use of gingiva-colored composites provides one such alternative and can be applied to varying presentations of the problem. While surgical treatment can be successful in re-creating favorable esthetic anatomy as well as achieving accurate tissue contour in cases when minor amounts of tissue are reconstructed, long-term results vary because of the vascularity and complexity of the interdental space. Factors such as cost, healing time, discomfort, and variable long-term results make surgery an unpopular choice. If tooth-colored restorative materials are utilized to restore cervical tooth exposure as a result of severe recession, the disproportionate appearance of the visible crown may give a dissatisfying result. Gingiva-colored composite provides dental practitioners with a versatile material that can be used to directly restore cervical defects caused by gingival recession, thus correcting the appearance of the gingival anatomy. It offers a treatment option that may increase patient satisfaction through the provision of a cost-effective, minimally invasive solution with highly esthetic results.

The most recent classification of periodontal diseases includes a new section on traumatic gingival lesions. Traumatic lesions of the gingiva are thought to be highly prevalent, yet the periodontal literature contains few references on the topic. The purpose of this article is to present a broad spectrum of traumatic gingival lesions of iatrogenic, accidental, and factitious origin. Twelve clinical cases were selected to document chemical (due to aspirin, snuff, and peroxide), physical (due to malocclusion, flossing, removable partial denture, oral piercing, and self-inflicted trauma), and thermal (due to overheated ultrasonic scaler, hot food, and ice) injury to the gingiva. Chemical, physical, and thermal gingival injuries of iatrogenic, accidental, or factitious origin can have a variety of presentations with overlapping clinical features. Although the appearance and associated symptoms of a gingival lesion may be suggestive of a particular traumatic etiology, useful or confirmatory diagnostic information is often discovered through careful history-taking. The management of gingival injuries typically requires elimination of the insult and symptomatic therapy. If permanent gingival defects resulted from the injury, periodontal plastic surgery may be necessary. A variety of chemical, physical, and thermal injuries may involve the gingiva. Accidental and iatrogenic injuries are often acute and self-limiting, while factitious injuries tend to be more chronic in nature.
Full Text Available Cairan sulkus gingiva (CSG adalah suatu produk filtrasi fisiologis dari pembuluh darah yang termodifikasi, karena asalnya dari darah maka komposisi CSG hampir sama dengan darah. Cairan ini diketahui berperan dalam patogenesis terjadinya penyakit atau kelainan periodontal, sehingga pengukuran terhadap adanya mediator-mediator inflamasi di dalam CSG ini dapat digunakan untuk mengevaluasi adanya faktor-faktor risiko terhadap kehilangan perlekatan gingiva hingga kerusakan tulang alveolar. Tujuan dari pemeriksaan CSG adalah untuk menganalisis bagaimana kondisi inflamasi dari jaringan periodontal yang kemungkinan akan mengakibatkan resorbsi jaringan periodontal yang lebih lanjut. Pada umumnya, dari CSG dapat dideteksi adanya indikator-indikator inflamasi seperti imunoglobulin, komplemen, aktivasi komplellen, komponen-komponen respon imun, serta indikator lain yang dapat berperan dalam resorbsi tulang alveolar. Dari pembahasan inidiharapkan operator dapat lebih awal mengidentifikasi pasien yang memiliki risiko menderita penyakit periotlontal, sehingga dapat dilakukan terapi lebih awal untuk mencegah perkembangan penyakit periodontallebih lanjut. Kesimpulan:Cairan sulkus gingiva dapat digunakan untuk mendeteksi indikator-indikator inflamasi yang berperan dalam terjadinya penyakit periodontal.

The presence of inflammatory infiltrates with B cells, specifically plasma cells, is the hallmark of periodontitis lesions. The composition of these infiltrates in various stages of homeostasis and disease development is not well documented. Human tissue biopsies from sites with gingival health (n = 29), gingivitis (n = 8), and periodontitis (n = 21) as well as gingival tissue after treated periodontitis (n = 6) were obtained and analyzed for their composition of B cell subsets. Ag specificity, Ig secretion, and expression of receptor activator of NF-κB ligand and granzyme B were performed. Although most of the B cell subsets in healthy gingiva and gingivitis tissues were CD19(+)CD27(+)CD38(-) memory B cells, the major B cell component in periodontitis was CD19(+)CD27(+)CD38(+)CD138(+)HLA-DR(low) plasma cells, not plasmablasts. Plasma cell aggregates were observed at the base of the periodontal pocket and scattered throughout the gingiva, especially apically toward the advancing front of the lesion. High expression of CXCL12, a proliferation-inducing ligand, B cell-activating factor, IL-10, IL-6, and IL-21 molecules involved in local B cell responses was detected in both gingivitis and periodontitis tissues. Periodontitis tissue plasma cells mainly secreted IgG specific to periodontal pathogens and also expressed receptor activator of NF-κB ligand, a bone resorption cytokine. Memory B cells resided in the connective tissue subjacent to the junctional epithelium in healthy gingiva. This suggested a role of memory B cells in maintaining periodontal homeostasis.

Gingival melanin pigmentation (GMP) occurs in all races of man. Although clinical melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly made by fair-skinned people with moderate GMP. The present study was undertaken to test the effectiveness of cryosurgical destruction of the gingival epithelium in the removal of gingival melanin pigmentation. The patient was a fair-skinned Ashkenazi Jew with moderate GMP who demanded any possible "cosmetic therapy" which would convert her "black gums" to "normal". Gingival cryosurgery was carried out by segments. A gas expansion cryoprobe cooled to -81 degrees C was applied to the gingiva for 10 s. Frozen sites thawed spontaneously within 1 min. Superficial necrosis became apparent within a week. Treated sites were covered by epithelium within 2 weeks following freezing and keratinization was completed after 3-4 weeks. The treated gingiva appeared normal and remained depigmented until the present time, 20 months following freezing. It is concluded that cryosurgery may prove to be the treatment of choice when gingival depigmentation is indicated.
Full Text Available Drug-induced gingival overgrowth or enlargement manifests as abnormal growth of the gingiva due to an adverse drug reaction (ADR in patients treated with anticonvulsants, immunosuppressants, and calcium channel blockers. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. It gradually becomes a source of pain and the condition often leads to disfiguration. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. It would seem pertinent to identify and explore possible risk factors and relating them with the treatment plan. This article throws light on respective drugs and their association with gingival overgrowth and approaches to treatment based on current knowledge and investigative observations.

Full Text Available Pemphigus Vulgaris (PV is an autoimmune intraepithelial blistering disease involving the skin and mucous membranes. Oral mucosa is frequently affected in patients with PV, and oral lesions may be the first sign of the disease in majority of patients. In some patients, oral lesions may also be followed by skin involvement. Therefore, timely recognition and therapy of oral lesions is critical as it may prevent skin involvement. Early oral lesions of PV are, however, often regarded as difficult to diagnose, since the initial oral lesions may be relatively nonspecific, manifesting as superficial erosions or ulcerations, and rarely presenting with the formation of intact bullae. Lesions may occur anywhere on the oral mucosa including gingiva; however; desquamtive gingivitis is less common with PV than other mucocutaneous conditions such as pemphigoid or lichen planus. This paper describes the case of a patient presenting with a one-year history of painful gingival, who is finally diagnosed as having PV.

Background: The presence of an adequate width of keratinized tissue is important to maintain a healthy dentogingival junction. In case of inadequate width of attached gingiva, the gingival augmentation procedure has been performed classically using the patient's own masticatory mucosa and more recently, using an acellular dermal allograft as the donor material. Aims: The aim of the clinical study was to evaluate and compare the effectiveness of free gingival graft (FGG) and acellular dermal matrix (ADM) allograft in the ability to increase the zone of attached gingiva. Materials and Methods: Fifteen patients with 30 sites showing the inadequate width of attached gingiva (≤1 mm) were enrolled for the split-mouth study. The width of keratinized gingiva and other clinical parameters were recorded at baseline and 12th month postoperatively. Statistical Analysis: The difference in clinical parameters within the group was assessed by Wilcoxon signed rank test. However, Mann–Whitney U-test was used to analyze the differences between test and control groups. Results: The width of attached gingiva increased significantly (P FGG site (49.7%). Though FGG was found to be more effective, clinicians can prefer ADM allograft because of its certain advantages over the FGG. Conclusion: ADM allograft has resulted in sufficient increase in width of attached gingiva although lesser than FGG. Considering the disadvantages of FGG, it can be concluded that ADM allograft can be used as an alternative to FGG in increasing width of attached gingival in certain clinical situations.

Autogenous gingival grafts are considered the "gold standard" for gingival augmentation, however they require a second surgical site for graft harvesting. Apically positioned flaps (APFs) represent an alternative method in soft tissue augmentation procedures. Limited information is available relative to the effectiveness of laser-mediated APF in augmenting keratinized gingiva (KG). The aim of this paper is to evaluate soft tissues changes following APF using CO2 laser in mandibular incisors with minimal KG and high labial frenum attachment. A total of 20 patients with minimal amount of KG (APF consisting of a single superficial horizontal incision just coronal to the mucogingival junction using CO2 laser, elevation of a split-thickness flap, and suturing of the flap to the periosteum in an apical position was performed. The apico-coronal height of KG was measured at baseline, and at 3, 6 and 12 months postoperatively. Uneventful healing was observed in all patients and an increase in KG of 2-3 mm was obtained. Most patients rated the procedure and the postoperative course as non painful. CO2 laser-assisted APF procedure is a minimally invasive treatment modality associated with reduced risk of bleeding and predictable increase in the height of KG.

Type I plasminogen deficiency (Plgdef) is an uncommon chronic inflammation of mucous membranes. Gingival enlargements usually proceed with progressive periodontal destruction and tooth-loss. Plasmin(ogen)-independent enzymatic mechanisms for fibrin clearance have already been discussed in the literature. Our primary objective was to verify, immunohistochemically, the occurrence of different enzymatic factors involved in tissue breakdown of inflamed compared to healthy gingiva. Secondly, we tried to find out, if these patients have a similar microbiological profile to the patients with known gingivitis and periodontitis. Immunohistochemical analysis of enzymes elastase, plasminogen (plg), cathepsin G, matrix-metalloproteinase (MMP)-3 and MMP-7 and of glycoprotein fibrinogen were performed with gingival tissues from 3 healthy controls, 8 patients with Plgdef and 3 patients with gingivitis and periodontitis. Furthermore, plaque from 5 patients with plasminogen deficiency were also obtained to determine the microbiological profile. Significantly high numbers of elastase positive leukocytes were detected in all samples. Staining for MMP-3 and MMP-7 was seen in samples with gingivitis and periodontitis with a stronger staining in samples with periodontitis by Plgdef. Fibrinogen was detectable in all samples. Staining for plg was stronger in samples with periodontitis than in other samples. Staining for cathepsin G was weak in gingivitis and periodontitis. Subgingival microbial flora showed elevated colony forming units of Prevotella intermedia/nigrescens, Fusobacterium spp., Eikenella corrodens, Porphyromonas gingivalis and viridans streptococci. Strong staining of elastase, MMP-3 and MMP-7 and weak staining of plg in Plgdef samples supports the plasmin(ogen) - independent fibrin clearance. Similar subgingival microbiological flora was observed in periodontitis with Plgdef as in other periodontal diseases. Further investigations should determine the exact pathomechanism
Full Text Available Localized gingival enlargement is often associated with specific systemic medication, abscess formation, trauma or reactive lesions. Scant literature is available reporting enlargement of gingiva due the metastasis of adenocarcinoma from lung. The case report presents a unique case of an adenocarcinoma in the lung metastasizing to the buccal and lingual interdental papillae of teeth numbering 34 and 35. A 72-year-old female was referred to the Mayo Clinic with a recent diagnosis of metastatic stage IV adenocarcinoma of the left lung presented with an abnormal mass located on the left posterior buccal keratinized tissue adjacent to teeth numbering 34-35. Biopsy of the lesion was performed for CK7, CK20, TTF-1 and p63. The tumor cells were positive for CK7 and TTF-1, and weakly positive for p63 suggesting a diagnosis of adenocarcinoma. The periodontist may be in the unique position to be the first oral health care provider to evaluate any biopsy suspicious intra-oral lesions.

The purpose of this study was to evaluate the microleakage in Class V cavities restored with a new gingiva-shaded microhybrid composite resin and with a conventional microhybrid composite resin using three different dentin bonding systems (DBS). Class V cavities were prepared in sixty freshly extracted human teeth with the incisal margin in enamel and the apical margin in dentin/cementum. Restored specimens, after thermocycling, were placed in 2% methylene blue solution for 24 hours. Longitudinal sections were obtained and studied with a stereomicroscope for assessment of the microleakage according to degree of dye penetration (scale 0-3). Data were analyzed with Kruskal-Wallis test and with Mann-Whitney U-test.IN THIS STUDY THERE WAS NO LEAKAGE IN ENAMEL: all the cavities showed no dye penetration at the incisal margins (located in enamel). None of the DBS used eliminated microleakage in apical margins (located in dentin or cementum): three-step total-etch and single-step self-etch were more effective in reducing microleakage in dentin margins when compared with two-step total-etch. This in vitro study concluded that microleakage in Class V cavities restored with the composite resins tested is similar.

Electron microscopy has been for decades a basic morphological method still used in diagnostic protocols of some pathological conditions affecting the ultrastructure of cells and extracellular matrix. The aim of this study was an ultrastructural description of gingiva of patients with Hunter syndrome and hereditary gingival fibromatosis. Gingival biopsies were obtained during surgical periodontal treatment from a 9-year-old boy with Hunter disease (with enzyme replacement therapy with recombinant human idursulphase) and a 15-year-old girl with hereditary gingival fibromatosis. Gingival samples obtained from the upper anterior region were processed and examined with transmission electron microscope. In the case of Hunter syndrome due to the genetic lack of one lysosomal enzyme, an intercellular accumulation of glycosaminoglycans occurs. Within the gingiva of a patient with Hunter syndrome we observed membrane-bound storage vesicles in the cytoplasm of fibroblasts, endothelial cells of capillaries, surface epithelial cells, mast cells, and macrophages. Despite a long-term enzyme replacement therapy which improves clinical manifestations of Hunter syndrome, on the cellular level we still found marked accumulations of glycosaminoglycans in the cytoplasm of different cells as well as in the extracellular matrix. Hereditary gingival fibromatosis is a benign, slowly progressive and non-inflammatory gingival enlargement with a predominance of randomly oriented collagen fibrils in the gingival lamina propria. Some of these fibrils exhibited loops. Another unusual ultrastructural finding is the presence of empty perinuclear space in the cytoplasm of epithelial cells. The origin and significance of these non-membrane bound spaces are unknown. In both genetically determined diseases, the electron microscopic examination may be useful, and physicians get relevant information about the progress of illness.
Full Text Available Abstract Introduction In modern medicine and dentistry the use of biomaterials is a fast developing field of increasing interest. Especially in dentistry the interaction between biomaterials like implant materials and the soft tissue in the oral cavity is in the focus of daily research. In this context the high importance of testing materials and their surfaces concerning their biocompatibility towards corresponding cells is very likely. For this purpose this study investigates cells derived from human gingival biopsies on different materials and surfaces. Methods Cells in this study were cultivated out of human biopsies by a grow out explant technique and were sub cultivated on titanium, zirconium dioxide and collagen membrane specimens. To characterise the cells on the material surfaces used in this study immunohistochemical and histological staining techniques as well as different methods of microscopy (light microscopy and SEM were applied. Results With the aid of the explant technique and the chosen cell cultivation method it was possible to investigate the human gingiva derived cells on different materials. The data of the present study show that the human gingival cells attach and proliferate on all three tested materials by exhibiting characteristic gingival keratinocyte protein expression even after long periods of culture e.g. up to 70 days. Conclusions It could be shown that the three tested materials titanium, zirconium dioxide and collagen membrane (and their special surfaces are good candidates for the application as materials in the dental gingival environment or, in the case of the collagen membrane as scaffold/cell-carrier for human gingival cells in tissue engineering.

To explore a gingival shade matching method and to evaluate the precision and accuracy of a dental spectrophotometer modified to be used in gingival color measurement. Crystaleye, a dental spectrophotometer (Olympus, Tokyo, Japan) with a custom shading cover was tested. For precision assessment, two experienced experimenters measured anterior maxillary incisors five times for each tooth. A total of 20 healthy gingival sites (attached gingiva, free gingiva and medial gingival papilla in anterior maxillary region) were measured,the Commission Internationale de I' Eclairage (CIE) color parameters (CIE L*a*b*) of which were analyzed using the supporting software. For accuracy assessment, a rectangular area of approximately 3 mm×3 mm was chosen in the attached gingival portion for spectral analysis. PR715 (SpectraScan;Photo Research Inc.,California, USA), a spectroradiometer, was utilized as standard control. Average color differences (ΔE) between the values from PR715 and Crystaleye were calculated. In precision assessment,ΔL* between the values in all the test sites and average values were from(0.28±0.16)to(0.78±0.57), with Δa*and Δb* from(0.28±0.15)to (0.87±0.65),from(0.19±0.09)to( 0.58±0.78), respectively. Average ΔE between values in all test sites and average values were from (0.62 ± 0.17) to (1.25 ± 0.98) CIELAB units, with a total average ΔE(0.90 ± 0.18). In accuracy assessment, ΔL* with control device were from(0.58±0.50)to(2.22±1.89),with Δa*and Δb* from(1.03±0.67)to(2.99±1.32),from(0.68±0.78)to(1.26±0.83), respectively. Average ΔE with the control device were from (2.44±0.82) to (3.51±1.03) CIELAB units, with a total average ΔE (2.96 ± 1.08). With appropriate modification, Crystaleye, the spectrophotometer, has demonstrated relative minor color variations that can be useful in gingival color measurement.

This study introduced the usefulness of LYVE-1 immunoreactivity for identification of lymphatic vessels in decalcified tissues, and demonstrated the fine distribution and organization of these vessels in mouse gingiva. After confirming the specificity of anti-mouse LYVE-1, frozen sections of mouse decalcified gingiva were immunostained with the antibody. The LYVE-1-positive lymphatic vessels were clearly found in the connective tissue under the gingival epithelium; these vessels appeared to pass through the lamina propria of the gingiva toward the alveolar crest and run along the external surface of the alveolar bone. The lymphatic vessels were sparse and apart from the oral gingival and sulcular epithelia, while they were dense adjacent to the junctional epithelium. The dense network of the lymphatic vessels adjacent to the junctional epithelium, which is apparently exposed to foreign antigens, may act as an efficient drainage pathway of the excessive interstitial fluid and immune cells, and play an active role in the immune defense of the gingiva. The present study also revealed the absence of lymphatic connection between gingiva and periodontal ligament.

Gingival epithelial cells are the first physical barrier against periodontal pathogenic microorganisms. Bacterial products may penetrate the epithelium and directly disturb its integrity. We investigated the clinical and cytomorphological status of the gingiva in children with gingivitis before and after low-level laser therapy. The study enrolled 130 children divided into three groups: group 1 comprised 50 children with chronic catarrhal gingivitis who received basic treatment, group 2 comprised 50 children with chronic catarrhal gingivitis who received low-level laser treatment in addition to basic treatment, and group 3 comprised 30 children with healthy gingiva as controls. Oral hygiene and the status of the gingiva were assessed using the appropriate indexes before and after treatment. Inflammation of the gingiva was monitored by cytomorphometric evaluation. Cytomorphometric analysis revealed a statistically significant difference (p gingivitis. Evaluation using clinical parameters showed that treatment of gingivitis with basic treatment was successful. Cytomorphometric analysis showed that after basic treatment the nuclei of the stratified squamous epithelial cells of the gingiva were reduced in size, although not to the size found in healthy gingiva. However, after adjuvant low-level laser therapy, the size of the nuclei of the stratified squamous epithelial cells in the gingiva matched the size of the nuclei in the cells in healthy gingiva.

The standard of care for increasing keratinized gingiva adjacent to teeth that do not require root coverage is the free gingival graft (FGG). A pilot study indicated that the use of a living cellular construct (LCC) could be effective in this clinical scenario. A pivotal, multicenter, randomized, within-patient, controlled, open-label trial was conducted (N = 96 patients). After removing the mucosa and keratinized gingiva from the test site, either an LCC or FGG was applied. The primary efficacy endpoint was the ability of the LCC to regenerate ≥2 mm keratinized gingiva at 6 months. Secondary measures were the same color and texture as the adjacent tissue, a 1-mm width of keratinized gingiva at 6 months, patient treatment preference, surgical site sensitivity at 1 week, and patient-reported pain after 3 days. Safety was assessed by reports of adverse events. At 6 months, the LCC regenerated ≥2 mm of keratinized gingiva in 95.3% of patients (81 of 85 patients; P FGG generated more keratinized gingiva than the LCC (4.57 ± 1.0 mm versus 3.2 ± 1.1 mm, respectively). The gingiva regenerated with the LCC matched the color and texture of the adjacent gingiva. All patients achieved ≥1 mm keratinized gingiva with the LCC treatment by 6 months, and more patients preferred treatment with the LCC than with the FGG. No difference in sensitivity or pain was noted between the treatments. The treatments were well tolerated, and reported adverse events were typical for this type of periodontal surgery. The use of an LCC may provide a safe and effective therapy for augmenting the zone of keratinized gingiva.

Squamous cell carcinoma (SCC) located in the maxillary gingiva and hard palate is relatively rare. There are few published guidelines for the treatment of SCC of the maxilla. The aim of the present study was to characterize the clinicopathologic features of SCC of the maxillary gingiva and hard palate and determine factors that predict outcome and lead to a strategic treatment plan. A retrospective cohort study of patients with SCC of the maxillary gingiva and hard palate was conducted from 2003 to 2012 at the Department of Oral and Maxillofacial Surgery, Affiliated Hospital of Stomatology, Nanjing Medical University. Clinicopathologic characteristics, treatments, outcome predictors, and 3- and 5-year overall survival rates were analyzed. The Kaplan-Meier method was used to evaluate 3- and 5-year overall survival rates. Univariate and multivariate Cox regression analyses were used to identify predictors of survival. A P value less than .05 was considered statistically significant. The 3- and 5-year survival rates of the 62 participants were 66.6 and 57.3%, respectively. Univariate analyses showed statistically significant (P plane area and received postoperative radiotherapy had a better prognosis. Elective neck dissection is recommended for management of T2 to T4 SCCs in the maxillary gingiva and hard palate. Postoperative radiotherapy can improve the prognosis and decrease the recurrence of SCC after the first premolar plane area. Copyright © 2015. Published by Elsevier Inc.
Conclusion: It was concluded that as the gingival disease progressed, the gingival leptin concentration decreased, whereas the plasma leptin concentration increased, indicating a possible correlation between leptin concentration in the gingiva and the risk of developing systemic disease like the cardiovascular disease.

The purpose of this retrospective study was to associate the amount of keratinized gingiva present in adolescents prior to orthodontic treatment to the development of gingival recessions after the end of treatment. The sample consisted of the intra-oral photographs and orthodontic study models from 209 Caucasian patients with a mean age of 11.20 +/- 1.83 years on their initial records and 14.7 +/- 1.8 years on their final records. Patients were either Angle Class I or II and were submitted to non-extraction orthodontic treatment. Gingival recession was evaluated by visual inspection of the lower incisors and canines as seen in the initial and final study models and intra-oral photographs. The amount of recession was quantified using a digital caliper and the observed post-treatment gingival margin alterations were classified as unaltered, coronal migration of the gingival margin or apical migration of the gingival margin. The width of the keratinized gingiva was measured from the mucogingival line to the gingival margin on the pre-treatment photographs. The teeth that developed gingival recession and those that did not have their gingival margin position changed did not differ in relation to the initial amount of keratinized gingiva (3.00 +/- 0.61 and 3.5 +/- 0.86 mm, respectively). Paradoxically, teeth that presented a coronal migration of the gingival margin had a smaller initial amount of keratinized gingiva (2.26 +/- 0.31 mm). The mean amount of initial keratinized gingiva did not predispose lower incisors and canines to gingival recession.
Full Text Available Background: The presence of an adequate width of keratinized tissue is important to maintain a healthy dentogingival junction. In case of inadequate width of attached gingiva, the gingival augmentation procedure has been performed classically using the patient's own masticatory mucosa and more recently, using an acellular dermal allograft as the donor material. Aims: The aim of the clinical study was to evaluate and compare the effectiveness of free gingival graft (FGG and acellular dermal matrix (ADM allograft in the ability to increase the zone of attached gingiva. Materials and Methods: Fifteen patients with 30 sites showing the inadequate width of attached gingiva (≤1 mm were enrolled for the split-mouth study. The width of keratinized gingiva and other clinical parameters were recorded at baseline and 12th month postoperatively. Statistical Analysis: The difference in clinical parameters within the group was assessed by Wilcoxon signed rank test. However, Mann–Whitney U-test was used to analyze the differences between test and control groups. Results: The width of attached gingiva increased significantly (P < 0.01 following both the treatments but comparatively lesser gain with ADM allograft (2.13 mm vs. 4.8 mm. ADM site had significantly more shrinkage (76.6% than FGG site (49.7%. Though FGG was found to be more effective, clinicians can prefer ADM allograft because of its certain advantages over the FGG. Conclusion: ADM allograft has resulted in sufficient increase in width of attached gingiva although lesser than FGG. Considering the disadvantages of FGG, it can be concluded that ADM allograft can be used as an alternative to FGG in increasing width of attached gingival in certain clinical situations.

Gingival health in the form of size, shape, consistency and appearance are essential components responsible for an attractive smile as well as may cause unpleasant appearance. Melanin pigmentation often occurs in the gingiva as a result of an abnormal deposition of melanin which can compromise the confidence level from the age of childhood. The present article describes and discusses the two cases of gingival melanin pigmentation in 12 and 13 years of female patient and their early surgical intervention with successful follow-up of 9 and 6 months. Patients were instructed to prevent sun exposure, intake of hot foods or beverages like cold drinks, tea, coffee and brushing immediately after surgery.

The presence and distribution of lymphatic vessels and mast cells in the gingiva under normal and pathological conditions have been reported by several studies, but the relationship between them during inflammatory lymphangiogenesis is virtually unknown. The aim of the present study was to investigate the lymphatic microvessel density (LMVD) and mast cell density (MCD) in the gingiva of patients with periodontal disease compared to normal-like gingiva. Gingival punch biopsies from 51 patients with periodontal disease were investigated. MCs and LVs were detected by double-immunohistochemistry, using primary antibodies against mast cell tryptase and D2-40. The inflammatory infiltrate was evaluated on a scale from 0 (absent) to +3 (severe inflammation). MCs and LVs were counted in the same microscopic field for each case at ×200 magnification. We found a significant increase in the number of both MCs and LVs in cases with mild and moderate inflammatory changes, followed by a slight decrease in cases with severe inflammation. We have shown a particular association between MCs and LVs that may support the contribution of MCs to the development of the lymphatic vasculature in inflammatory conditions. MCD correlated with LMVD in all cases with mild and moderate inflammatory changes, but not in cases with severe inflammation. No correlation was found between MCD/LMVD and the density of the inflammatory infiltrate. Our results suggest the potential involvement of MCs in the induction and maintenance of lymphangiogenesis in the gingiva of patients with periodontal disease in the early steps of evolution.

Tissue-engineering therapies using undifferentiated mesenchymal cells (MSCs) from intra-oral origin have been tested in experimental animals. This experimental study compared the characteristics of undifferentiated mesenchymal stem cells from either periodontal ligament or gingival origin, aiming to establish the basis for the future use of these cells on regenerative therapies. Gingiva-derived mesenchymal stem cells (GMSCs) were obtained from de-epithelialized gingival biopsies, enzymatically digested and expanded in conditions of exponential growth. Their growth characteristics, phenotype, and differentiation ability were compared with those of periodontal ligament-derived mesenchymal stem cells (PDLMSCs). Both periodontal ligament- and gingiva-derived cells displayed a MSC-like phenotype and were able to differentiate into osteoblasts, chondroblasts, and adipocytes. These cells were genetically stable following in vitro expansion and did not generate tumors when implanted in immunocompromised mice. Furthermore, under suboptimal growth conditions, GMSCs proliferated with higher rates than PDLMSCs. Stem cells derived from gingival biopsies represent bona fide MSCs and have demonstrated genetic stability and lack of tumorigenicity. Gingiva-derived MSCs may represent an accessible source of messenchymal stem cells to be used in future periodontal regenerative therapies.

Full Text Available Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70% reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves detachment from the surrounding cells, regulation of cell motility, invasion, survival, proliferation, and evasion of the immune system. Clinical presentation of metastatic tumors is variable, which may create diagnostic dilemma or may lead to erroneous diagnosis. Metastatic tumors clinically mimic as dental infections. Metastasis to the oral soft tissue from lung cancer, especially gingiva is a rare condition. Metastasis to the gingiva can affect the oral function, speech, and nutrition. Most of the cases in the literature reported that lesion presented in oral soft tissues before the diagnosis of primary tumors. Here we report a case of 62-year-old male patient with metastasis from lung to the gingiva, where the metastasis was detected before primary tumor.
Full Text Available Chronic periodontitis (CP, an infectious disease resulting in inflammation within the periodontal tissue, is the main cause of adult tooth loss. CP is a multi-factorial disorder and the interaction between multiple genetic and environmental factors results in the manifestation of this disease. Recent researches in periodontitis has focused on cytokine gene polymorphisms that play important role in periodontal inflammation, but few studies investigated histological change that occur during CP in the supporting tissue of teeth. The aims of this study were to investigate the association of IFN-γ +874 A/T polymorphisms and quantitative parameters of interdental gingiva in CP patients. The study samples were interdental gingiva biopsies from 60 individuals including 38 patients and 22 healthy subjects. After determination of IFN-γ +874 A/T gene polymorphism by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR, patients were divided in three subgroups: 10 AA, 18 AT and 10 TT. After slides preparation, quantitative parameters were estimated by Cavalieri’s point-counting method. Statistical analyses were performed using Mann-Whitney and Kruskal-Wallis test to compare differences between groups. The volume density (Vv of epithelium, connective tissue and its components were significantly different between the control and CP groups (P<0.05. Statistically significant differences in the Vv of collagenous and non-collagenous matrix of interdental gingiva between AA, AT and TT groups were found (P<0.05. Result of present study shows that IFN-γ +874 A/T is strongly associated with some quantitative parameters of connective tissue constituents of interdental papilla in CP patients.

The histological appearance of the gingiva in children with Down's syndrome (DS) was studied with special reference to inflammatory involvement and innervation. A dense infiltration of inflammatory cells was seen in the propria of most of the DS patients, including a few polymorphonuclear leucocytes. A hyperplasia of the epithelium was also found. The innervation of the gingiva was studied using immunohistochemistry. Nerve fibers as well as nerve bundles immunoreactive to neurofilament (NF) were seen in the propria, while occasionally intraepithelial NF fibers were observed. Calcitonin gene-related peptide (CGRP)-immunoreactive fibers and fiber bundles were also visualized, but they were less abundant than NF fibers. The density of NF and CGRP fibers and fiber bundles was estimated by semiquantitative evaluation. A higher density of NF and CGRP immunoreactive structures was observed in the propria of DS patients compared to the control subjects, while no obvious alteration was seen in their distribution in the propria. In addition, sparsely distributed fibers immunoreactive to peptide histidine isoleucine amide (PHI) and vasoactive intestinal polypeptide (VIP) fibers as well as neuropeptide Y (NPY) and tyrosine hydroxylase (TH) were seen, mainly surrounding blood vessels. A few substance P (SP) fibers were also found, mostly close to the epithelium. No obvious differences of these sparsely distributed fibers were seen in the DS patients compared to controls. Thus, a profound inflammatory involvement of the gingiva of DS patients is seen concomitant with a hyperinnervation of the presumed sensory component of the gingival innervation. In contrast, no alterations were seen in the density of neuronal markers related to autonomic nerve fibers. The sensory hyperinnervation observed is probably not specifically related to DS, but may be due to a sprouting of afferent nerves induced by the inflammatory reaction. However, factors released from the sensory afferents could

The purpose of this study is to evaluate the morphology of the mid-substance and fan-like extension fibres of ACL during knee motion with reference to the femoral attachment. This study used six fresh-frozen cadaveric knees and 22 embalmed cadaveric knees to macroscopically evaluate morphological changes in the ACL attachment during knee motion. Three embalmed specimens fixed at knee extension and another three specimens fixed at 120° flexion were used for histologic observations. The fan-like extension fibres were adhered to the bone surface and the fibre location and orientation in relation to the femoral surface did not change, regardless of the knee flexion angle, while the orientation of the mid-substance fibres in relation to the femur did change during knee motion. During knee flexion, a fold in the ACL femoral attachment was observed at the border between the mid-substance and the fan-like extension fibres. The attachment of the mid-substance fibres was significantly smaller than the attachment of the fan-like extension fibres. The present study clarified anatomic and histologic character of the mid-substance fibres and fan-like extension fibres, and provided critical information for future clinical and biomechanical studies concerning both two different fibres. Specifically for ACL reconstruction, it is difficult to reconstruct the natural fan-like extension fibres by creating a tunnel at the femoral and tibial ends of each fibre bundle, although the mid-substance fibres can be reconstructed by such procedures.

Dark colored stains, ranging from light blue to black, are disorders which often arise in the gums. Effective elimination of these melanotic disorders can be attempted by destroying the superficial layers of the gingiva. Treatment with monoline 514 nm green light (1.5 W, 300 ms, 0.5 mm spot size) produced by an Argon laser demonstrates, in clinical and histological controls, that due to good 514 nm light absorption by the pigment, elimination of the stains can be obtained and, in spite of the fact that the first layers of the tissue are destroyed, restoration of the mucosa status is optimal, giving excellent aesthetic results.

The present invention provides a method for producing an anterior cruciate ligament ex vivo. The method comprises seeding pluripotent stem cells in a three dimensional matrix, anchoring the seeded matrix by attachment to two anchors, and culturing the cells within the matrix under conditions appropriate for cell growth and regeneration, while subjecting the matrix to one or more mechanical forces via movement of one or both of the attached anchors. Bone marrow stromal cells are preferably used as the pluripotent cells in the method. Suitable matrix materials are materials to which cells can adhere, such as a gel made from collagen type I. Suitable anchor materials are materials to which the matrix can attach, such as Goinopra coral and also demineralized bone. Optimally, the mechanical forces to which the matrix is subjected mimic mechanical stimuli experienced by an anterior cruciate ligament in vivo. This is accomplished by delivering the appropriate combination of tension, compression, torsion, and shear, to the matrix. The bioengineered ligament which is produced by this method is characterized by a cellular orientation and/or matrix crimp pattern in the direction of the applied mechanical forces, and also by the production of collagen type I, collagen type III, and fibronectin proteins along the axis of mechanical load produced by the mechanical forces. Optimally, the ligament produced has fiber bundles which are arranged into a helical organization. The method for producing an anterior cruciate ligament can be adapted to produce a wide range of tissue types ex vivo by adapting the anchor size and attachment sites to reflect the size of the specific type of tissue to be produced, and also adapting the specific combination of forces applied, to mimic the mechanical stimuli experienced in vivo by the specific type of tissue to be produced. The methods of the present invention can be further modified to incorporate other stimuli experienced in vivo by the
Full Text Available Hyperimmunoglobulin E syndrome (HIES, also known as Job′s syndrome, is a rare primary immunodeficiency characterized by eczema, recurrent skin and lung infections, elevated serum IgE, and connective tissue and skeletal abnormalities. Individuals with HIES share a characteristic facial appearance and many oral manifestations including retained primary dentition, a high-arched palate, variations of the oral mucosa and gingiva, and recurrent oral candidiasis. An 18-year-old lady presented with gingival swelling, bleeding from the gums, recurrent skin infections, and recurrent respiratory infections with intermittent fever. After thorough extra oral, intra oral and radiographic examination, serological investigations were performed. Growth of candida hyphae in the biopsy specimen of gingiva and increased levels of serum IgE with typical extra oral findings established the diagnosis as Job′s syndrome (hyper IgE syndrome. Treatment with anti-fungal antibiotics and phase-I therapy including scaling and root planing followed by gingivoplasty using diode laser (980 nm was performed. HIES was previously defined on the basis of clinical manifestations and laboratory markers that were not specific to the disease. With the identification of STAT3 mutations as the cause of HIES, we can definitively characterize the disease at molecular and immunologic levels. This case emphasizes the role of the dentist in the diagnosis of rare syndromes which alters the treatment plan.

Using the model of oxodipine-induced gingival hyperplasia in beagle dogs, we investigated the collagen fibres of the hyperplastic gingiva by measuring the polarization colours from Picrosirius-red stained sections. The predominant polarization colours of the thick collagen fibres (1.6-2.4 microns diameter) of male oxodipine-treated dogs were greenish-yellow to yellow, while in controls and in female oxodipine-treated dogs, the same size fibres mostly appeared orange and red. These differences may be indicative of gender variation in the genesis of hyperplastic gingiva in calcium channel blocker treated dogs.

In a previous investigation, children with Down's syndrome (DS) showed an earlier, more rapid and more extensive gingival inflammation than normal healthy control children. These differences in gingival inflammation may be the result of aberrant morphology of the gingiva related to the genetic disorder in DS children. The aims of the present study were (i) to describe the structural composition of "normal" gingiva in DS compared to control children, (ii) to analyse the histological changes in the gingiva during plaque development and (iii) to investigate whether the clinical findings could be supported by morphological observations. The study was carried out in 8 DS and 8 matched control children. Their ages ranged from 5-10 years. Gingival normality was guaranteed by strict oral hygiene procedures. During a period of 21 days in which oral hygiene was abolished, gingival biopsies were taken from buccal sites of deciduous teeth following a predetermined schedule on days 0, 7, 14 and 21. Results on day 0 showed no morphological differences between the DS and control children regarding oral epithelium, junctional epithelium or connective tissue. During the experimental phase of the study, the amount of plaque accumulation in the DS children gave rise to a more extensive gingival inflammation than in the control children. The gingival inflammation in the DS group started earlier and included: (1) an acute inflammatory response, (2) an increase of the junctional epithelium area, (3) an increase of the infiltrated connective tissue area (ICT) and (4) a decrease in collagen fibre density of about 35-40% compared to day 0. The same phenomena were not seen until 7 days later in the control group. Conversely, the development of a perivascular lymphocyte infiltrate (LI) in the DS children was delayed compared to the control group. This may be caused by the impaired delayed-type hypersensitivity response in DS children. The development of 2 separate infiltrates (ICT and LI) in
Full Text Available Fourteen kilodalton phospholipase A2 molecules (PLA2 are classified into two groups, I- and II-PLA2, and only the latter has been considered to play a pathogenetic role in various forms of tissue inflammation. Previously we demonstrated high PLA2 activity in gingival crevicular fluid (GCF of patients with periodontal disease, without determining the group of the enzyme involved. In this study, the activity, groups and levels of enzyme in gingiva taken from 13 sites of periodontal disease were determined using both biochemical and radioimmunological methods. A linear correlation between the activity and the level of II-PLA2 was observed. No I-PLA2 was found in any of the samples tested. These data suggest that the PLA2 activity found in the GCF of patients with periodontal disease does not belong to the I-PLA2 but to the II-PLA2 group.

Full Text Available Oral focal mucinosis (OFM is a rare soft tissue lesion of unknown aetiology. Clinically, it is most commonly found on the gingiva and presents as a painless, sessile or pedunculated mass. Histologically, it is characterized by focal myxoid degeneration of underlying connective tissue. Fifty-three-year-old patient reported with a painless, firm and fibrous gingival overgrowth present from 7 to 8 months. Clinical examination and patient's history pointed towards "irritation fibroma". An excisional biopsy was performed. The histopathologic diagnosis was established as OFM, an uncommon and poorly characterized type of lesion. This case report stresses on the fact that prediagnosis of OFM is almost impossible. Thus though rare, OFM must be considered in the differential diagnosis of soft tissue overgrowths in oral cavity.
Full Text Available Myofibromas are benign uncommon fibroblastic tumors of the soft tissue, bone, or internal organs affecting all ages. These lesions histopathologically may mimic many other soft tissue tumors of the oral cavity such as spindle cell tumors of neurogenic and smooth muscle cell origin, thus leading to misdiagnosis and mistreatment. This case report describes a rare benign tumor, which presented as a soft tissue swelling on posterior gingiva. Surgical excision of the lesion was carried out under local anaesthesia. Histopathologic and immunohistochemical examination confirmed the diagnosis of myofibroma. Myofibroma should be included in the clinical differential diagnosis of masses of the oral soft tissues; however immunohistochemical examination is essential to establish an accurate diagnosis.

A smile is a mesmerizing expression of joy, success, courtesy and reveals self-confidence. The harmony of the smile is determined not only by the shape, position and the color of teeth, but also by the gingival architecture. Gingival tissues form an important part of what we can consider to be a pleasing smile. The elegance of this pleasant smile could be, affected by highly pigmented gingiva. This gingival pigmentation occurs as a result of melanin granules, which are produced by melanoblast. Although melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly sort by people with moderately pigmented gingiva. This case report highlights, a case of excessive gingival display and hyperpigmentation treated with anterior crown lengthening and gingival depigmentation using the scalpel technique.
Full Text Available Aims: To assess and compare the thickness of gingiva in the anterior maxilla using radiovisiography (RVG and cone beam computed tomography (CBCT and its correlation with the thickness of underlying alveolar bone. Settings and Design: This cross-sectional study included 10 male subjects in the age group of 20–45 years. Materials and Methods: After analyzing the width of keratinized gingiva of the maxillary right central incisor, the radiographic assessment was done using a modified technique for RVG and CBCT, to measure the thickness of both the labial gingiva and labial plate of alveolar bone at 4 predetermined locations along the length of the root in each case. Statistical Analysis Used: Statistical analysis was performed using Student's t-test and Pearson's correlation test, with the help of statistical software (SPSS V13. Results: No statistically significant differences were obtained in the measurement made using RVG and CBCT. The results of the present study also failed to reveal any significant correlation between the width of gingiva and the alveolar bone in the maxillary anterior region. Conclusions: Within the limitations of this study, it can be concluded that both CBCT and RVG can be used as valuable tools in the assessment of the soft and hard tissue dimensions.

Guided bone regeneration (GBR) is frequently used in oral implantology. It is unclear to what extent GBR affects the periodontium of adjacent teeth. Therefore, the present study quantifies changes in the proximal gingiva and bone levels at these teeth in 30 patients. Staged surgery involved a standard GBR treatment, randomly using resorbable membranes with a bone substitute or non-resorbable membranes with or without a bone substitute, followed by fixture installation at 6 months and abutment connection a further 6 months later. The data were sampled at each surgery and analysed using MANOVA. Twelve months after GBR, there was on average a small but statistically significant amount of proximal gingival recession (0.75 mm) and bone resorption (0.34 mm) observed, of which 50% was the result of GBR surgery. No significant differences were found between the different GBR treatment modalities. It is concluded that GBR treatment may have a small negative effect on the levels of the free gingival margin and alveolar bone at adjacent teeth, which is in most patients not clinically relevant.

Periodontal inflammation is associated with morphological changes in the blood vessels which may influence the regulation of gingival blood flow (GBF). Our aim was to adapt the heat provocation test to the human gingiva to assess vascular reactivity in periodontal inflammation. GBF was recorded by Laser Doppler Flowmetry before and after heat provocation in healthy volunteers (n = 50). Heat was generated either by warm saline or a halogen lamp. The latter method was also utilized for a heat test in non-smoking and smoking patients with periodontal inflammation. The circulatory parameters were correlated to the inflammatory marker, i.e. gingival crevicular fluid (GCF) production measured by Periotron. Local application of heat caused a rapid, significant and transient increase in GBF regardless of the method used. The increase in the speed and not in the concentration of moving blood cells was responsible for increased GBF. Higher GCF values were correlated with increased peak flow, flux pulse amplitude and faster restoration of GBF after the test in non-smokers, but not in smokers. The heat test could be a valuable tool to check the vascular reactivity of gingival vessels. Moderate periodontal inflammation may facilitate gingival vascular responsiveness which can be suppressed by smoking.

Hasil pengukuran ketebalan epitel menunjukkan perbedaan yang tidak signifikan pada kelompok kontrol positif dengan perlakuan (p>0,05, namun menunjukkan perbedaan yang signifikan pada kelompok perlakuan dengan kontrol negatif (p0.05 while there was significant difference between treatment group and negative control group (p<0.05 observed at 3, 7, and 14 days. The conclusion of this research is that the application of sweet orange peel extract gel accelerates epithelialization of wound healing process in labial mandibular gingiva of Sprague Dawley rats.
Full Text Available Uterine leiomyosarcoma (LMS is a rare tumor constituting 1% of all uterine malignancies. This sarcoma demonstrates an aggressive growth pattern with an high rate of recurrence with hematologic dissemination; the most common sites are lung, liver, and peritoneal cavity, head and neck district being rarely interested. Only other four cases of metastasis in the oral cavity have been previously described. The treatment of choice is surgery and the use of adjuvant chemotherapy and radiation has limited impact on clinical outcome. In case of metastases, surgical excision can be performed considering extent of disease, number and type of distant lesions, disease free interval from the initial diagnosis to the time of metastases, and expected life span. We illustrate a case of uterine LMS metastasis in the upper buccal gingiva that occurred during chemotherapy in a 63-year-old woman that underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy for a diagnosis of LMS staged as pT2bN0 and that developed lung metastases eight months after primary treatment. Surgical excision of the oral mass (previously misdiagnosed as epulis at a dental center and contemporary reconstruction with pedicled temporalis muscle flap was performed in order to improve quality of life. Even if resection was achieved in free margins, “local” relapse was observed 5 months after surgery.

Maintaining healthy teeth and soft oral tissue is important. Clinical research has shown manual toothbrushes with end-rounded filaments to cause significantly less gingival abrasions than those without end-rounding. Tapered filaments are an alternative to end-rounded filaments, but there is no solid evidence for their effectiveness. For the interdental spaces that the toothbrush doesn't reach, the use of special oral hygiene aids is advised. Clinical studies of gingivitis patients have shown that both interdental brushes and plastic-rubber bristles reduce gingivitis after 4 weeks of use. Plastic-rubber bristles result in a significant improvement in the tendency for interdental bleeding compared with interdental brushes, and they cause less abrasion of the gingiva. Other factors that can potentially traumatise soft and hard oral tissue are oral piercings. Wearing oral piercings is not without risk. Tongue and lip piercings are associated with the risk of gingival recession, and tongue piercings are associated with tooth fractures. To prevent the risk of complications, patients should be discouraged from wearing oral piercings.

The purpose of this study was to evaluate the effect of collagen matrix with apically positioned flap (APF) on the width of keratinized gingiva, comparing to the results of APF only and APF combined with free gingival graft (FGG) at the second implant surgery. Nine patients were selected from those who had received treatments at the Department of Periodontics, Chosun University Dental Hospital, Gwangju, Korea. We performed APF, APF combined with FGG, and APF combined with collagen matrix coverage respectively. Clinical evaluation of keratinized gingival was performed by measuring the distance from the gingival crest to the mucogingival junction at the mid-buccal point, using a periodontal probe before and after the surgery. The ratio of an increase was 0.3, 0.6, and 0.6 for the three subjects in the APF cases, 3, 5, and 7 for the three in the APF combined with FGG case, and 1.5, 0.5, and 3 for the three in the APF combined with collagen matrix coverage case. This study suggests that the collagen matrix when used as a soft tissue substitute with the aim of increasing the width of keratinized tissue or mucosa, was as effective and predictable as the FGG.
Full Text Available Multifactorial is the etiology of periodontal diseases and there is homeostasis in balance from host and local factor. To determine the diagnosis and etiology accurately, ideal examination clinically radiographically and laboratorically should be done. SInce laboratoric xamination is expensive, we need to search a naccurate clinical indicator which can reflect the internal equality to the external local factors. The purpose of this study was to prove the equality of the clinical indicator (gingival index to the laboratoric indicator, especially associated with regeneration and host resistance. Nineteen patients with periodontal disease for whom ginigvectomy was indicated were divided into 2 groups: the first group got gingivectomy with the application of periodontal pack, while for the second group sterile gauze was applied as control. Excised gingiva was examined pathobiologically for PMNL. macrophages, lymphocytes and fibroblasts. The examination was done on day 1, 5 and 7 after gingivectomy of the 2 groups. The Anova and Multiple Regression Test showed an equality of GI to the laboratoric component examined.

Mesenchymal stem cells (MSCs) are capable of regenerative and immunomodulatory functions in cell-based therapies in a variety of human diseases and injuries; however, their therapeutic efficacy and potential side effects remain major obstacles in clinical applications. We report here a 3D spheroid culture approach to optimize stem cell properties and therapeutic effects of human gingiva-derived mesenchymal stem cells (GMSCs) in mitigation of experimental oral mucositis. Under growth condition of ultra-low attachment, GMSCs spontaneously aggregated into 3D spheroids and exhibited distinct early stem cell phenotype characterized by elevated expression Stro-1 and CXC chemokine receptor 4 (CXCR-4) as well as OCT-4 and Nanog, 2 important transcriptional factors relevant to stem cell properties, and decreased expression of MSC-associated markers, including CD29, CD90, and CD105. Functionally, spheroid GMSCs are capable of enhanced multipotency and augmented secretion of several chemokines and cytokines relevant to cell migration, survival, and angiogenesis. More importantly, spheroid GMSCs expressed increased levels of reactive oxygen species, hypoxia-inducible factor (HIF)-1 and -2α, and manganese superoxide dismutase, which correlated with improved resistance to oxidative stress-induced apoptosis. Using an in vivo murine model of chemotherapy-induced oral mucositis, we demonstrated that spheroid-derived GMSCs possessed better therapeutic efficacy than their adherent cells in reversing body weight loss and promoting the regeneration of disrupted epithelial lining of the mucositic tongues. These findings suggest that 3D spheroid culture allows early stemness preservation and potentially precondition GMSCs for enhanced mitigation of oral mucositis. PMID:21689066

Full Text Available Periodontal disease is the most widespread oral disease in dogs which if left untreated results in significant pain to the pet and loss of dentition. The objective of this study was to identify bacterial species in canine plaque that are significantly associated with health, gingivitis and mild periodontitis (<25% attachment loss. In this survey subgingival plaque samples were collected from 223 dogs with healthy gingiva, gingivitis and mild periodontitis with 72 to 77 samples per health status. DNA was extracted from the plaque samples and subjected to PCR amplification of the V1-V3 region of the 16S rDNA. Pyrosequencing of the PCR amplicons identified a total of 274 operational taxonomic units after bioinformatic and statistical analysis. Porphyromonas was the most abundant genus in all disease stages, particularly in health along with Moraxella and Bergeyella. Peptostreptococcus, Actinomyces, and Peptostreptococcaceae were the most abundant genera in mild periodontitis. Logistic regression analysis identified species from each of these genera that were significantly associated with health, gingivitis or mild periodontitis. Principal component analysis showed distinct community profiles in health and disease. The species identified show some similarities with health and periodontal disease in humans but also major differences. In contrast to human, healthy canine plaque was found to be dominated by Gram negative bacterial species whereas Gram positive anaerobic species predominate in disease. The scale of this study surpasses previously published research and enhances our understanding of the bacterial species present in canine subgingival plaque and their associations with health and early periodontal disease.

In a previous experimental gingivitis study, it was shown that in children with Down's syndrome (DS), gingival inflammation started earlier, was more extensive and developed faster, than in normal healthy control children. In both groups, the start of the process was accompanied by an acute inflammatory response and an increase of the infiltrated connective tissue area (ICT). The purpose of the present study was to investigate how these facts were reflected at a cytological level. The study was carried out in 8 DS and 8 matched control children. Their ages ranged from 5-10 years. A "normal" healthy gingiva was attained after strict oral hygiene procedures. During a period of 21 days in which oral hygiene was abolished, gingival biopsies were taken on days 0, 7, 14, and 21. In both groups, junctional epithelium (JE) and ICT contained low numbers of polymorphonuclear leucocytes (PMNs). The start of the inflammation (day 7 for the DS and day 14 for the control children) was marked by a significant positive correlation between the numbers of PMNs in the JE and the ICT, and a significant increase of the numbers of PMNs in ICT. In ICT, a concomitant decrease in collagen fibre density was observed. In the control group, the decrease correlated with the numbers of PMNs in ICT, which suggests that this collagen breakdown is caused by PMN products. After the initial decrease, the collagen fibre density remained fairly constant in this group throughout the study. In the DS group, there was a tendency to a further decrease in the ICT3 area, correlated with the numbers of PMNs in ICT.(ABSTRACT TRUNCATED AT 250 WORDS)

This study investigated the characteristics related to attachment of 42 depressed psychiatric patients and 42 non-depressed psychiatric controls. The depressed subjects demonstrated an anxious pattern of attachment, characterized by either intense care-seeking in relation to their attachment figure or angry withdrawal from their attachment figure when their desire for security was frustrated. The results are discussed in terms of Bowlby's attachment construct.
Full Text Available Theory of attachment primarily described early relationships between a child and his caretakers. In the last twenty years there is a growing interest in adult attachment research. Theories and research findings of adult attachment stem from two different methodological approaches. The first approach measures adult attachment through Adult Attachment Interview (AAI; Main, 1991 where the attachment is assessed through the narratives of adult people of their early child experiences with their primary caretakers. The second approach measures adult attachment with the help of self-evaluative questionnaires, developed by (a Hazan and Shaver (1987 who started this approach in the field of personality and social psychology, and (b Bartholomew and Horowitz (1991. Research shows that there is significant correlation between early and adult attachment style. Attachment styles are passed from generation to generation. Basic adult attachment styles are: securely attached, preoccupied, fearful-avoidant, dismissing-avoidant and disorganized. Previous research using Barholomew and Horowitz (1991 Relationship Questionnaire on 176 Slovenian students showed that 48% students are securely attached, 29% are fearful-avoidant, 10% are dismissing-avoidant, and 13% have preoccupied attachment style. Theory of attachment is very useful for understanding the behavior and subjective experiences of children and adults. It is applicable to different contexts (psychotherapy, counseling, education .... The paper proposes further research focused on integration of adult attachment styles and types of object relations measured by Test of object relations (Žvelc, 1998 and Pictorial test of Separation and Individuation (Žvelc, 2003.

To evaluate shear bond strength of a gingiva-colored indirect composite to three implant framework materials, before and after thermocycling, and verify the effect of surface pre-treatment for each framework. Commercially pure titanium (CP-Ti), American Dental Association (ADA) type 4 casting gold alloy (Type IV) and zirconia ceramics (Zirconia) were assessed. For each substrate, 96 disks were divided into six groups and primed with one of the following primers: Alloy Primer (ALP), Clearfil Photo Bond (CPB), Clearfil Photo Bond with Clearfil Porcelain Bond Activator (CPB+Activator), Estenia Opaque Primer (EOP), Metal Link (MLP) and V-Primer (VPR). The specimens were then bonded to a gingiva-colored indirect composite (Ceramage Concentrate GUM-D). Shear bond strengths were measured at 0 and 20 000 thermocycles and data were analyzed with the Steel-Dwass test and Mann-Whitney U-test. Shear bond strengths were significantly lower after thermocycling, with the exception of Type IV specimens primed with CPB (p = 0.092) or MLP (p = 0.112). For CP-Ti and Zirconia specimens, priming with CPB or CPB+Activator produced significantly higher bond strengths at 0 and 20 000 thermocycles, as compared with the other groups. For Type IV specimens, priming with ALP or MLP produced higher bond strengths at 0 and 20 000 thermocycles. Shear bond strength of a gingiva-colored indirect composite to CP-Ti, gold alloy and zirconia ceramics was generally lower after thermocycling. Application of a hydrophobic phosphate monomer and polymerization initiator was effective in maintaining bond strength of CP-Ti and zirconia ceramics. Combined use of a thione monomer and phosphoric monomer enhanced the durable bond strength of gold alloy.

Three-dimensional cell culture systems provide a convenient in vitro model for the study of complex cell-cell and cell-matrix interactions in the absence of exogenous substrates. The current study aimed to evaluate the osteogenic differentiation potential of gingiva-derived stem cells cultured in two-dimensional or three-dimensional systems. To the best of our knowledge, the present study is the first to compare the growth of gingiva-derived stem cells in monolayer culture to a three-dimensional culture system with microwells. For three-dimensional culture, gingiva-derived stem cells were isolated and seeded into polydimethylsiloxane-based concave micromolds. Alkaline phosphatase activity and alizarin red S staining assays were then performed to evaluate osteogenesis and the degree of mineralization, respectively. Stem cell spheroids had a significantly increased level of alkaline phosphatase activity and mineralization compared with cells from the two-dimensional culture. In addition, an increase in mineralized deposits was observed with an increase in the loading cell number. The results of present study indicate that gingiva-derived stem cell spheroids exhibit an increased osteogenic potential compared with stem cells from two-dimensional culture. This highlights the potential of three-dimensional culture systems using gingiva-derived stem cells for regenerative medicine applications requiring stem cells with osteogenic potential.
Full Text Available Attachment which is defined as strong emotional bond people develop for significant others have been investigated by researchers for long years. Attachment theory proposes that attachment patterns developed in the first stages of life are carried onto next stages of life with internal working models. Additionally it is also proposed that attachment patterns are important to determine individual’s social-emotional competence. This study aims to review how attachment patterns differ according to life stages, continuity/discontiniuty of attachment patterns developed in the first stages of life and evaluate the relations between attachment patterns and social-emotional competence. The basic features of social relations model, relationship between attachment patterns and identity development, and risk taking behavior in adolescence have also been investigated in this review.

The connective tissue (CT) is responsible for stability and function of the whole periodontium. It consists of cells, which are embedded in the extracellular matrix. Collagen plays the main role for the function of the periodontal unit. Collagen types I, III, IV, V and VI are distributed in a different pattern in all periodontal tissues, as has been here demonstrated in the gingiva and alveolar bone. Collagen type I, as a characteristic collagen type of the hard tissues, has been demonstrated by thick collagen fibers in the alveolar bone and in the gingival connective tissue. It can be differentiated from the thinner collagen type III fibers, which are localized in the gingiva (especially under the basement membrane of the epithelium) as well as only in the bone marrow stroma. The epithelium, blood vessels and nerves contain the characteristic collagen type IV in their basement membrane Filamentous (collagen type V) and microfibrillar (collagen type VI) components demonstrate different patterns of distribution, especially around the bone cells and in contrast to the other collagen types of fibrillar networks in the gingival CT. This morphological differentiation of the extracellular matrix components of the periodontium allows conclusions in the pathological and inflammatory processes as well as in the regenerative and reparative procedures.

Full Text Available Purpose: This study aimed to reexamine the relationship between mandibular incisor inclination, prominence and vertical changes in position, and keratinized gingival tissue (KT height changes labial to the mandibular incisors after orthodontic treatment with and without augmented corticotomy (Cort. Materials and Methods: Two orthodontically treated groups of 35 individuals each, with (Cort and without (conventional [Conv] alveolar decortication and augmentation bone grafting (periodontally accelerated osteogenic orthodontics [PAOO], were matched for sample size, gender, mandibular premolar extractions, pretreatment age, posttreatment observation period, and pretreatment KT height in this case–controlled retrospective study. Pre- and post-treatment lateral cephalometric radiographs were evaluated for mandibular incisor vertical, inclination, and prominence changes. Results: As reported previously (Wilcko 2015, KT height had significantly increased by 0.78 mm (P = 0.001 in the Cort group and decreased by 0.38 mm (P = 0.002 in Conv on an average of 1.5 years after completion of active orthodontic therapy. In this study, Cort mandibular incisors proclined and protruded significantly during therapy while Conv incisors did not. Changes in mandibular incisor inclination and prominence explained neither the decrease in keratinized gingiva height in Conv nor the KT height gain in Cort. Conclusions: In spite of mandibular incisor proclination and protrusion, orthodontic therapy combined with alveolar decortication and augmentation bone grafting resulted in a clinically significant increase in keratinized gingiva height 1.5 years' posttreatment.
Full Text Available The heads of nine 2.5 to 3-year-old Nile crocodiles (Crocodylus niloticus were obtained from a commercial farm where crocodiles are raised for their skins and meat. The animals from which these specimens originated were clinically healthy at the time they were slaughtered. A detailed description of the macroscopic and microscopic features of the palate and gingivae of the Nile crocodile is presented and the results are compared with published information on this species and other Crocodylia. The histological features are supplemented by information supplied by scanning electron microscopy. Macroscopic features of interest are the small conical process situated at the base of the first two incisors of the maxilla, the distribution of cobbled units on the palate, and the broad dentary shelf forming the rostral aspect of the mandible. Histologically the palate and gingivae did not differ significantly from each other and both regions showed a presence of Pacinian-type corpuscles. Two types of sensory structures (taste receptors and pressure receptors were identified in the regions examined, both involving modification of the epithelium and the underlying connective tissue.

Autistic disorder is a neuropsychiatric disorder which begins in the first years of life with delays and deviance in social, communicative and cognitive development and with restricted repertoire of activities and interests. It is thought that autistic children do not form attachments to parents or caregivers because of their difficulties in social interaction. Yet, the findings of the studies demonstrate evidences for the existence of attachment between autistic children and their caregivers. The aim of the present study is to review the studies that examine the attachment behaviors in autism. Autistic children show similar attachment behaviors when compared to children with normal development, children with other psychiatric disorders, children with Down syndrome and mentally retarded children. Children with autism prefer their mothers to strangers and attempt to remain close to them as much as other children. However they do not engage in attention sharing behaviors such as pointing or showing objects. They also do not seem to recognize the meaning of facial expressions and emotions. Although autism does not exclude the development of secure attachment relationships, it may delay the development of secure attachment and change the behavioral patterns related with attachment security. It is concluded that the awareness of the parents and the clinicians might help to establish treatment alternatives that preserve and improve the attachment behaviors of autistic children.

The present study was investigating the predictive role of maternal mentalizing and general as well as depressive symptom burden for attachment security at the end of the first year on a sample of 44 mother-child-dyads from a low-risk community study. Maternal mentalizing was assessed in a multidimensional way as Reflective Functioning (off-line) and Mind-Mindedness (on-line). The design was longitudinal measuring maternal Mind-Mindedness from a videotaped mother-child-play-interaction at the age of three months. General and depressive symptom burden was assessed using the SCL-90-R when the children were nine months old. Maternal attachment and Reflective-Functioning, using the Adult-Attachment-Interview, as well as children's attachment behavior, using the Strange-Situation-Test, were investigated at the age of twelve months. Secure maternal attachment was associated with higher Reflective Functioning, higher frequency of Mind-Mindedness and lower general and depressive symptom burden. A moderation-analysis showed a statistical trend (p = .08) that the interaction of the frequency of mind-related comments, general symptom severity and maternal attachment has a predictive value for infantile attachment security. Results can be tentatively interpreted that mothers with insecure attachment who had a lower general symptom burden and who related to their three-months old babies with a high frequency of mind-related-comments were more likely to have securely attached children. Thus, results may serve as a groundwork for projects aiming to prevent the transmission of insecure attachment by strengthening maternal Mind-Mindedness and working on the reduction of maternal general symptom burden.

Old age is likely to cause a crisis in one's life because of the vulnerabilities it brings up, acting as stressful elements disrupting the elder's feeling of security. It leads to the activation of what is called his attachment system, consisting in attachment styles and interpersonal emotional regulation strategies. To recover a higher sense of safety, the elder would refer to his attachment figures, that is to say closed people paying attention to him, showing towards him availability and consideration. However older adults particularly see their tolerance threshold lowered, regarding an accumulation of losses (true or symbolic) and stressful events within their lifetime. In a psychological and organic exhaustion phenomenon, the risk is to wear out the interpersonal emotional regulation strategies. These are as much vulnerabilities that may increase psychiatric decompensation, including depression. To resolve the tension of this period and to found a necessary secure feeling, the elder will have to redesign the attachment links previously settled and proceed to adjustments to this new context. The need of relational closeness comes back in the elders' attachment behaviour, counting on attachment figures not only to help their loneliness or dependency, but essentially to support them in a narcissist and affective way. That is why attachment theory enlightens the late life period, such as the new challenges older adults have to face. Many studies recognize its value in understanding the transition to old age, but without proposing conceptualization. We aim first to focus on attachment conception to say how much it is relevant with elderly, and then to describe specific terms of attachment within this population in order to better understand those patients. To finish, we must think about new therapeutic proposals taking into consideration the attachment perspective for a better understanding of old age transition.

Anterior sacral meningocele is a rare condition presenting as a lower abdominal mass. One such case was seen in a baby girl aged 2 months, who was admitted with abdominal distension and urinary difficulty for one week. She had a lower abdominal mass which investigated by MRI, turned out to be an anterior sacral meningocele causing her symptoms. The meningocele was excised successfully via an open abdominal approach. Postoperative recovery and follow-ups remained uneventful. Presentation, various diagnostic modalities and treatment options for an anterior sacral meningocele are briefly discussed.

The anterior sacral meningocele is a rare form of spinal dysraphism located in the presacral extraperitoneal space. It is generally asymptomatic and appears as a small pelvic mass. We present a case of a 10 year-old male that develops a bacteria meningitis because of a pararectal abscess that is connected with an anterior sacral meningocele. We successfully treated it using a posterior approach. The aim of the surgery is to repair the dural defect and to obliterate the communication between the thecal sac and the herniation defect. The posterior approach is the simplest and most effective surgical technique because the lower risk of neurological injury than the anterior approach.

The glenohumeral joint is the most mobile articulation in the body and the most commonly dislocated diarthroidal joint. Anterior dislocation is by far the most common direction and can lead to instability of the glenohumeral joint, which ranges from subtle increased laxity to recurrent dislocation. Overtime, understanding of anterior shoulder dislocations and the resulting instability has improved. Likewise, significant advances in arthroscopic equipment have allowed use of the arthroscope to address anatomically the various lesions that cause instability. This article reviews the anatomy, pathophysiology, clinical evaluation, and treatment of anterior shoulder instability.

Full Text Available Objective:The aim of the present study is to examine the factors related aggression in Iranian and Indian school children. Method: Attachment security (dependency, availability, and total considered as the variable. The KSS questionnaire was administrated students in the 5th grade; 300 were Iranian and 300 were Indian consisted of 150 boys and 150 girls. Results: Attachment security demonstrated significant negative correlations with aggression in the boys, girls and the total Iranian sample. The dependency on mothers was the only case with insignificant correlation.In the Indian sample, attachment security was also found to be significantly negatively correlated with aggression. The only exception was the correlation between mother's availability and aggression in girls, which was not significant Conclusion: It is important that parents treat their children in a tender, manner so that a secure attachment develop between them.
ABSTRACT ANTERIOR CRANIOFACIAL RESECTIONS Tumors involving the anterior skullbase are not easily accessible to surgical therapy, but it is no longer an impossible task due to constant improvements in diagnostic methods, surgical techniques and cooperation between the different specialists. While this type of surgery earlier had a very low successrate or at the best resulted in massive facial deformities, we see today that tumors often are possible to resect completely and that the p...

Our goal was to test the hypothesis that breastfeeding is associated with enhanced infant-mother attachment and its antecedent maternal sensitivity. Breastfeeding intent and practice were assessed by questionnaires administered to 152 mothers between 32 weeks of gestation and 12 months postpartum. Early maternal sensitivity was measured by the Sensitivity to Cues subscale of the Nursing Child Assessment Satellite Training Feeding Scale at 3 months, and quality of the mother-infant interaction was measured by the Nursing Child Assessment Satellite Training Feeding Scale at 6 months. Security of attachment was evaluated by the Ainsworth Strange Situation at 12 months. A direct relationship between attachment security and breastfeeding practice was not identified. The quality of the mother-infant interaction at 6 months, rather than the type of feeding, predicted security of attachment. However, mothers who chose to breastfeed displayed greater sensitivity in dyadic interactions with their infants 3 months postnatally than those who chose to bottle feed, and intended breastfeeding duration prenatally correlated with sensitivity 3 months postpartum. Although a path analysis failed to demonstrate contributions of early breastfeeding duration to either sensitivity or security, it did substantiate a significant path between prenatal breastfeeding intent and attachment security mediated by sensitivity. In addition, multivariate analyses revealed that early sensitivity among breastfeeding mothers was an independent predictor of the duration of any and exclusive breastfeeding during the first year. Although the quality of the dyadic interaction in infancy, rather than feeding type, is predictive of attachment security, mothers who choose to breastfeed display enhanced sensitivity during early infancy that, in turn, may foster secure attachment. Among breastfeeding mothers, higher sensitivity is associated with longer duration of breastfeeding during the first postpartum year
Full Text Available Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD, which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST, Pelvic Organ Prolapse Quantification (POP-Q evaluation, Incontinence Impact Questionnaire (IIQ-7, and Urogenital Distress Inventory (UDI-6 scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

Lipoma is relatively uncommon in the oral cavity. Among the intraoral regions, lipoma involving the gingiva or gingivobuccal fold is relatively infrequent. We report the case of a patient with lipoma extending superiorly from the mandibular gingivobuccal fold to the gingiva. In addition to the case report, we retrospectively reviewed 207 patients with intraoral lipoma reported in Japan from 1987 to 2004. The most frequent site of development was the buccal mucosa (40.6%), followed by the tongue (17.9%), lip (12.6%), gingiva (8.7%), oral floor (6.8%), gingivobuccal fold and palate (4.8%), and others (3.9%). Occurrence tended to be more frequent in males (57.5%) than in females (42.5%). Relative to age, frequency peaked among patients in the 7th (27.3%) and 6th decades (25.1%), respectively, followed in descending order by the 5th (14.8%) and 8th decades (13.1%). The majority of patients (86.3%) were at least 40 years. The most frequent size was 10-19 mm (37.5%), followed by 0-9 mm (27.8%) and 20-29 mm (14.6%), and tumors 30 mm or larger were relatively infrequent. Histopathological types in order of descending frequency were lipomas (69.0%), fibrolipomas (27.4%), and others (3.5%). The male:female ratio was 1.7:1 for lipoma and 1:1.6 for fibrolipoma.

The aim of the current study was to investigate basic emotions and attachment in a sample of 86 stroke patients. We included a control group of 115 orthopedic patients (matched for age and cognitive status) without brain lesions to control for unspecific general illness effects of a traumatic recent event on basic emotions and attachment. In order to measure basic emotions and attachment style we applied the Affective Neuroscience Personality Scale (ANPS) and the Attachment Style Questionnaire (ASQ). The stroke patients showed significantly different scores in the SEEKING, SADNESS, and ANGER subscales of the ANPS as well as in the Relationship as Secondary Attachment dimension of the ASQ when compared to the control group. These differences show a pattern influenced by lesion location mainly as concerns basic emotions. Anterior, medial, left, and subcortical patients provide scores significantly lower in ANPS-SEEKING than the control group; ANPS-SADNESS scores in anterior, right, medial, and subcortical patients were significantly higher than those of the control group. ANPS-ANGER scores in posterior, right, and lateral patients were significantly higher than those in the control group; finally, the ANPS-FEAR showed slightly lower scores in posterior patients than in the control group. Minor effects on brain lesions were also individuated in the attachment style. Anterior lesion patients showed a significantly higher average score in the ASQ-Need for Approval subscale than the control group. ASQ-Confidence subscale scores differed significantly in stroke patients with lesions in medial brain regions when compared to control subjects. Scores at ANPS and ASQ subscales appear significantly more correlated in stroke patients than in the control group. Such finding of abnormalities, especially concerning basic emotions in stroke brain-lesioned patients, indicates that the effect of brain lesions may enhance the interrelation between basic emotions and attachment with

Children with autism are able to show secure attachment behaviours to their parents/caregivers. Most studies on attachment in children with autism used a (modified) Strange Situation Procedure (SSP) to examine attachment security. An advantage of the Attachment Q-Sort (AQS) over the SSP is that it can be attuned to the secure-base behaviour of…

Full Text Available Various psychodynamic processes may underlie the development of psychogenic pain disorder such as conversion, the displacement of affect, or narcissistic defenses. However, many of the processes suggested are related to a disorder of affect regulation. The term affect regulation in psychoanalytic literature refers to phenomena which are often described by the concept of alexithymia. Empirical observations suggest that alexithymia is correlated to insecure attachment, especially an insecure dismissing representation of attachment. Psychodynamic psychotherapy in psychogenic pain disorder should focus on the reintegration of split-off affects which may provoke intensive counter-transference and which in order to be used therapeutically must be linked to attachment experiences within and outside of the therapeutic relationship.

To review the safety and efficacy of anterior vaginal compartment pelvic organ prolapse surgery. Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and the Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials [RCT] or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 case reports. The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. A grade A recommendation usually depends on consistent level 1 evidence. A grade B recommendation usually depends on consistent level 2 and/or 3 studies, or "majority evidence" from RCTs. A grade C recommendation usually depends on level studies or "majority evidence" from level 2/3 studies or Delphi processed expert opinion. A grade D "no recommendation possible" would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi. Absorbable mesh augmentation of anterior compartment native tissue repair improves the anatomical outcome compared with native tissue repair alone with no increased complication rate in meta-analysis of 2 RCTS (grade B). Biological grafts in meta-analysis have improved anatomical outcomes with no change in subjective outcomes compared with native tissue repairs (grade B). There is conflicting level 1 evidence to support porcine dermis and a single RCT to support small intestine submucosa as graft agents in anterior compartment prolapse surgery (grade B). Consistent level 1 data support a superior anatomical outcome for polypropylene mesh compared with a biological graft in the anterior compartment. Mesh exposure rate was

An area of deep, long-standing recession on a mandibular first premolar was treated for root coverage in a 40-year-old woman. The recession was 6.0 mm deep with a probing depth of 2.0 mm, and there was no attached gingiva. A thick (1.5-mm) free autogenous epithelium and connective tissue graft from the palate was placed to the cementoenamel junction of the tooth after instrumentation and tetracycline conditioning of the root surface. The tooth and facial soft tissues were removed in block section 10.5 months later. At the time of extraction, there had been a gain of 5.0 mm of root coverage, and there was 5.0 mm of keratinized gingiva on the facial aspect. The probing depth was 1 mm. Histologic measurement showed 4.4 mm of new attachment and 4.0 mm of new bone growth. The coronal extent of the new attachment and new bone were in an area previously exposed by recession.

This study evaluated the temperature increase in swine gingival temperature after exposure to light emitted by a Polywave(®) LED light curing unit (LCU, Bluephase 20i, Ivoclar Vivadent). After local Ethics Committee approval (protocol 711/2015), 40 pigs were subjected to general anesthesia and the LCU tip was placed 5mm from the buccal gingival tissue (GT) close to lower lateral incisors. A thermocouple probe (Thermes WFI, Physitemp) was inserted into the gingival sulcus before and immediately after exposure to light. Real-time temperature (°C) was measured after the following exposure modes were applied: High Power (20s-H, 40s-H, and 60s-H) or Turbo mode (5s-T), either with or without the presence of rubber dam (RD) interposed between the LCU tip and GT (n=10). The presence of gingival lesions after the exposures was also evaluated. Peak temperature (°C) and the temperature increase during exposure over that of the pre-exposure baseline value (ΔT) data were analyzed using 2-way ANOVA followed by Bonferroni's post-hoc test (α=5%). A binary logistic regression analysis determined the risk of gingival lesion development. Without RD, no significant difference in ΔT was observed among 20s-H, 40s-H, and 60s-H groups, which showed the highest temperature values, while the 5s-T exposure showed the lowest ΔT, regardless of RD. RD reduced ΔT only for the 20s-H group (p=0.004). Gingival lesions were predominantly observed using 40s-H, with RD, and 60s-H, with and without RD. Exposure to a LCU light might be harmful to swine gingiva only when high radiant exposure values are delivered, regardless of the use of RD. Copyright © 2017 The Academy of Dental Materials.

The present study examined the interplay of attachment to God, attachment to mother, and attachment to father with respect to adjustment (hope, self-esteem, depression) for 130 early and 106 middle adolescents in Singapore. Results showed that the parental attachments were generally linked (in expected directions) to adjustment. God attachment, however, had unique results. At the bivariate level, God attachment was only linked to early adolescents' self-esteem. When considered together with parental attachments (including interactions), God attachment did not emerge as the key moderator in attachment interactions and yielded some unexpected results (e.g., being positively linked to depression). These results are discussed viz-a-viz the secure base and safe haven functions that God and parental attachments may play during adolescence.

Septic arthritis following intra-capsular penetration of the knee by external fixation devices is a complication of traction/fixation devices inserted in the lower extremity [1,2]. The authors were unable to find reference to or exact measurements of the capsular attachments relating to the distal femur documented in the current literature. This study aimed to demonstrate the capsular attachments and reflections of the distal femur to determine safe placements of wires or traction devices. The attachments of the capsule to the distal femur were measured in 10 unembalmed cadaveric knees. Capsular attachments were measured anteriorly at the maximal extension of the supra-patella pouch. Medially and laterally measurements were expressed as percentages related to the maximal AP diameter of the distal femur. Mean distance from the centre of the anterior part of the notch to the superior fold was 79.5mm (Range 48.1-120.7 mm). The medial capsular reflections measured in a plane from the adductor tubercle to the anterior edge of the medial femoral condyle demonstrated the capsular reflection was attached an average of 57% back from the anterior edge (Range 41-74%). Laterally the capsular reflections on a line drawn from the maximal diameter in the sagittal plane were attached an average of 48% from the anterior reference point (Range 33-57%). Measuring the reflections at 45 degrees to the long axis of the femur in the sagittal plane the attachment was an average of 51% from the anterior reference point. Capsular reflections varied among specimens. Medially the capsule attachment was up to 74% of diameter of distal femur at the level of the adductor tubercle. Therefore, the insertion of distal femoral traction pins or similar should be placed proximal to the adductor tubercle and no further than 25% of the distance to the anterior cortex. Care is also needed to ensure pins do not travel to exit too anteriorly on the lateral side as capsular attachments were found to be up

Many people suffer from dry mouth (xerostomia) due to radiotherapy treatment of head and neck cancer, diseases like Sjogren's syndrome or as adverse effects to prescribed medications. Salivary substitute products like gels or sprays are often used for treatment. Efficacy of those oral care products are regularly assessed by validated or even not validated questionnaires. To determine the adhesion effect over time more objectively a new and sensitive method was established. The following study was designed to assess the dwell time of different oral care products in vitro. Two different types of surfaces were covered with oral care products and washed using a definite protocol with artificial saliva salt solution. First, oral care gels or oral care sprays were spread to a polystyrene surface of 2.25 cm(2), then onto cell based three-dimensional gingiva models. The surfaces were washed ten times with artificial saliva salt solution. The resulting washing solutions were examined using mid infrared spectroscopy in order to detect ingredients of the oral care products. All assessed oral care gels or oral care sprays and their components were detected very sensitive. Even traces of the products were detected in the eluent and thus enabled to differentiate the dwell times of the different products. In general, the dwell time of oral care gels on polystyrene or gingiva models was longer than that of oral care sprays. The use of gingiva models improved the differentiation between different products. MIR spectroscopy turned out to be a sensitive method to detect salivary substitutes. Differences between single components and different products can be detected. The described method is a simple, reliable and easy process to evaluate the dwell time of oral care products in vitro and thus a useful tool to design optimised salivary substitute products. This is an in vitro study. No ethics or consent was required for this study.

To present the largest series reported so far of brimonidine induced granulomatous anterior uveitis. Retrospective chart review of patients with chronic glaucoma on treatment with brimonidine presenting with anterior uveitis. 19 eyes of 12 patients with chronic glaucoma developed anterior uveitis with granulomatous keratic precipitates after being treated with brimonidine for periods of 7 days to 5 years (mean 19.7 months, +18.6 months). One patient had a gap of 1 year between onset in one eye and onset in the other. Ten eyes (52.6%) had concurrent granulomatous conjunctivitis; 16 eyes were pseudophakic. Stopping brimonidine led to complete, rapid resolution of uveitis in all patients, in most cases (11 eyes, 58%) without topical corticosteroids. No recurrences have occurred after withdrawal of brimonidine, over a follow-up period of 12-52 months (mean 27.9 months, +13.8 months). Ophthalmologists should be aware of this easily reversible uveitis syndrome that is induced by a common glaucoma medication. Familiarity with this entity is essential in making the correct diagnosis and avoiding unnecessary investigations and interventions.

Full Text Available We studied the clinical presentation and management of four patients with anterior urethral valves; a rare cause of urethral obstruction in male children. One patient presented antenatally with oligohydramnios, bilateral hydronephrosis and bladder thickening suggestive of an infravesical obstruction. Two other patients presented postnatally at 1 and 2 years of age, respectively, with poor stream of urine since birth. The fourth patient presented at 9 years with frequency and dysuria. Diagnosis was established on either micturating cystourethrogram (MCU (in 2 or on cystoscopy (in 2. All patients had cystoscopic ablation of the valves. One patient developed a postablation stricture that was resected with an end-to-end urethroplasty. He had an associated bilateral vesicoureteric junction (VUJ obstruction for which a bilateral ureteric reimplantation was done at the same time. On long-term follow-up, all patients demonstrated a good stream of urine. The renal function is normal. Patients are continent and free of urinary infections. Anterior urethral valves are rare obstructive lesions in male children. The degree of obstruction is variable, and so they may present with mild micturition difficulty or severe obstruction with hydroureteronephrosis and renal impairment. Hence, it is important to evaluate the anterior urethra in any male child with suspected infravesical obstruction. The diagnosis is established by MCU or cystoscopy and the treatment is always surgical, either a transurethral ablation or an open resection. The long-term prognosis is good.

Full Text Available Background: The palatal approach of anterior superior alveolar (P-ASA using WAND injection was reported to effectively provide a profound bilateral maxillary anesthesia of the soft tissue of anterior one-third of the palate and facial gingivae extending from canine to canine which lasted for more than an hour thus making it ideal for scaling root planing and minor periodontal procedures in the anterior maxilla. Our study suggests that the conventional P-ASA injection is of very short duration and the extent of anesthesia was not profound and consistent. This has not been reported earlier in the literature. Materials and Methods: Thirty-five cases (20 males and 15 females, who underwent scaling, root planing and minor periodontal surgical procedures such as abscess drainage, gingivectomy, and frenectomy in the maxillary anterior region in the age range of 19–45 years was assessed for the efficacy of the P-ASA injection. After the administration of the P-ASA injection, the subjective and the objective symptoms were used to evaluate the extent and duration of the anesthesia at 10, 15, and 20 min. Results: This study suggests that the conventional P-ASA injection technique does not provide anesthesia for more than 20 min. Wilcoxon matched pairs test was used to compare the effect of anesthesia at the different time intervals and the results were found to be statistically significant (P < 0.05. Conclusions: The conventional P-ASA injection technique is of very short duration and does not demonstrate effectiveness in periodontal surgery of the anterior maxilla.
Full Text Available Context: The gingival biotype is of utmost importance for esthetics and biologic function. Anatomical characteristic of periodontium such as gingival thickness (GT, width of keratinized gingiva, and alveolar bone morphology will determine the behavior of periodontium when subjected to physical, chemical, or bacterial insult or during therapeutic procedure. Aims: The aim of this study was to correlate the GT with gingival width (GW, probing depth (PD, and papillary fill (PF in relation to maxillary anterior region. Settings and Design: Undergraduate dental students and interns from a dental college in Navi Mumbai were enrolled in the study according to the inclusion criteria. Six teeth per subject were assessed; a total of 2178 maxillary anterior teeth were examined. Subjects and Methods: Subjects were examined clinically for GT, width of keratinized gingiva, pocket depth, and interdental PF. The data obtained was tabulated and subjected to statistical analysis. Statistical Analysis Used: Spearman's correlation analysis test was performed to find the correlation of GT with GW, PD, and PF. Results: Positive correlation was found between GT and GW (r = 0.241. No significant correlation could be found between GT and PD; and between GT and PF. Conclusions: The present study confirmed a positive correlation between GT and GW. A weak negative correlation was found between GT and PD.

Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries.

Full Text Available On the basis of the study of recent scientific literature about the development of attachment, the author answers the following questions: which are the postulates the theory of attachment has about the stability of the patterns of attachment, which level of stability in the patterns of attachment from infancy to adulthood these studies illuminate and which factors significantly influence the (instability of the patterns of attachment in time. The theory of attachment assumes that normal circumstances elicit stability. Changes, however, can be the result of important events influencing the sensitivity of the object of attachment. Agreement has not yet been reached regarding the percentage of stability in the patterns of attachment. There is more agreement regarding attachment in adulthood than that in childhood. The results depend on the size and characteristics of the subjects of the research, the measuring instruments, type of data analysis etc. The author concludes that attachment is a dynamic system influenced by significant changes in life (the cognitive development of the child, external care, parents' divorce, different stressful situations. As the influence of stressful events on the individual person' s quality of attachment is examined, it is necessary to consider also his/her temperamental characteristics, role of other people in their lives, etc.

The attachment of Neisseria gonorrhoeae to eukaryotic cells grown in tissue culture was analyzed by use of light and electron microscopy and by labeling of the bacteria with (/sup 3/H)- and (/sup 14/C)adenine. Isogenic piliated and nonpiliated N. gonorrhoeae from opaque and transparent colonies were studied. The results of light microscopy studies showed that the gonococci attached to cells of human origin, including Flow 2000, HeLa 229, and HEp 2. Studies using radiolabeled gonococci gave comparable results. Piliated N. gonorrhoeae usually attached in larger numbers than nonpiliated organisms, and those from opaque colonies attached more often than isogenic variants from transparent colonies. Day-to-day variation in rate of attachment was observed. Scanning electron microscopy studies showed the gonococcal attachment to be specific for microvilli of the host cells. It is concluded that more N. gonorrhoeae from opaque colonies, as compared with isogenic variants from transparent colonies, attach to eukaryotic cells grown in tissue culture.

To evaluate and compare the shear-bond strength of a gingiva-colored indirect composite material to three different implant framework materials (zirconia ceramics, gold alloy, and titanium), and to investigate the effect of surface pretreatment by air-particle abrasion and four priming agents. A gingiva-colored indirect composite (Ceramage) was bonded to three framework materials (n = 80): commercially pure titanium (CP- Ti ), ADA (American Dental Association)-type 4 casting gold alloy (Type IV), and zirconia ceramics (Zirconia) with or without airborne-particle abrasion. Before bonding, the surface of the specimens was treated using no (control) or one of four priming agents: Alloy Primer (ALP), Estenia Opaque Primer (EOP), Metal Link Primer (MLP), and V-Primer (VPR). Shear-bond strength was determined after 24-h wet storage. Data were analyzed using Steel-Dwass for multiple comparisons, and Mann-Whitney U-test (P = 0.05). For both CP- Ti and Zirconia substrates, three groups, ALP, EOP, and MLP, showed significantly higher bond strengths (P gold alloy. © 2012 John Wiley & Sons A/S.

Full Text Available Attachment patterns influence actions, thoughts and feeling through a person’s ‘Inner Working Model’. Speech charged with attachment-dependent content was proposed to modulate the activation of cognitive-emotional schemata in listeners. We performed a 7 Tesla rest-task-rest fMRI-experiment, presenting auditory narratives prototypical of dismissing attachment representations to investigate their effect on 23 healthy males. We then examined effects of participants’ attachment style and childhood trauma on brain state changes using seed-based functional connectivity (FC analyses, and finally tested whether subjective differences in responsivity to narratives could be predicted by baseline network states. In comparison to a baseline state, we observed increased FC in a previously described ‘social aversion network’ including dorsal anterior cingulated cortex (dACC and left anterior middle temporal gyrus (aMTG specifically after exposure to insecure-dismissing attachment narratives. Increased dACC-seeded FC within the social aversion network was positively related to the participants’ avoidant attachment style and presence of a history of childhood trauma. Anxious attachment style on the other hand was positively correlated with FC between the dACC and a region outside of the ‘social aversion network’, namely the dorsolateral prefrontal cortex, which suggests decreased network segregation as a function of anxious attachment. Finally, the extent of subjective experience of friendliness towards the dismissing narrative was predicted by low baseline FC-values between hippocampus and inferior parietal lobule. Taken together, our study demonstrates an activation of networks related to social aversion in terms of increased connectivity after listening to insecure-dismissing attachment narratives. A causal interrelation of brain state changes and subsequent changes in social reactivity was further supported by our observation of direct
Full Text Available The anterior cingulate cortex (ACC has a role in attention, analysis of sensory information, error recognition, problem solving, detection of novelty, behavior, emotions, social relations, cognitive control, and regulation of visceral functions. This area is active whenever the individual feels some emotions, solves a problem, or analyzes the pros and cons of an action (if it is a right decision. Analogous areas are also found in higher mammals, especially whales, and they contain spindle neurons that enable complex social interactions. Disturbance of ACC activity is found in dementias, schizophrenia, depression, the obsessive-compulsive syndrome, and other neuropsychiatric diseases.

In this article, we explore the cultural-political tensions and ambiguities of urban ecology, by way of following how activists move and translate between ‘familiar’ and ‘public’ engagements in the green city. Empirically, we locate our exploration in and around Nordhavnen (The North Harbor......), a large-scale sustainable urban development project in Copenhagen. Invoking Laurent Thévenot’s pragmatic sociology of ‘regimes of engagement’, we sketch a culturally sensitive approach to urban ecological activism, highlighting the critical moral capacities involved in building new forms of ‘commonality...... of urban politics as inclusive learning processes, more hospitable to a wider diversity of familiar attachments to cities and their ecologies....
Attachment theory is a useful way to understand the bond between children and the people with whom they have emotional ties--usually caregivers. The theory can also help us to understand any adult relationship that provides closeness and a sense of attachment, especially in times of stress or need. Understanding the nature, cause and effect of the role and function of attachment from a training and development perspective, and different styles of attachment, may improve the quality of the mentoring experience for both mentors and mentees.

Even though John Bowlby (1907-1990) is generally regarded as the founder of attachment theory, Mary Ainsworth’s (1913-1999) contribution is considerable and goes beyond the design of the Strange Situation Procedure and the introduction of maternal sensitivity as decisive for a secure attachment

Gingival recession can be defined as the apical shift of the marginal gingiva from its normal position on the crown of the tooth to levels on the root surface beyond the cemento-enamel junction. The aetiology of this condition is multifactorial, but can result from a traumatic occlusion. The long-term prognosis of teeth with localised gingival recession can be uncertain. Successful management of these cases may involve either orthodontic or periodontal treatment in isolation or in combination. To describe two patients in which localised gingival recession associated with anterior crossbites were corrected with orthodontic appliances. A 2 x 4 appliance and an upper removable appliance were used to correct the crossbites. Correction of the anterior crossbites resulted in a clinical improvement of the gingival recession. The aetiology and management of localised gingival recession is discussed. Simple orthodontic appliances can be used to provide interceptive treatment to correct localised crossbite and enhance the overall long-term prognosis of the lower incisors. To achieve optimal results multidisciplinary involvement is recommended.

Full Text Available Introduction. The purpose of this study is to describe the inner synovial membrane (SM of the anterior elbow capsule, both qualitatively and quantitatively. Materials and Methods. Twenty-two cadaveric human elbows were dissected and the distal humerus and SM attachments were digitized using a digitizer. The transepicondylar line (TEL was used as the primary descriptor of various landmarks. The distance between the medial epicondyle and medial SM edge, SM apex overlying the coronoid fossa, the central SM nadir, and the apex of the SM insertion overlying the radial fossa and distance from the lateral epicondyle to lateral SM edge along the TEL were measured and further analyzed. Gender and side-to-side statistical comparisons were calculated. Results. The mean age of the subjects was 80.4 years, with six male and five female cadavers. The SM had a distinctive double arched attachment overlying the radial and coronoid fossae. No gender-based or side-to-side quantitative differences were noted. In 18 out of 22 specimens (81.8%, an infolding extension of the SM was observed overlying the medial aspect of the trochlea. The SM did not coincide with the outer fibrous attachment in any specimen. Conclusion. The humeral footprint of the synovial membrane of the anterior elbow capsule is more complex and not as capacious as commonly understood from the current literature. The synovial membrane nadir between the two anterior fossae may help to explain and hence preempt technical difficulties, a reduction in working arthroscopic volume in inflammatory and posttraumatic pathologies. This knowledge should allow the surgeon to approach this aspect of the anterior elbow compartment space with the confidence that detachment of this synovial attachment, to create working space, does not equate to breaching the capsule. Alternatively, stripping the synovial attachment from the anterior humerus does not constitute an anterior capsular release.

Mesenchymal stem cells (MSCs) are capable of self-renewal and differentiation into multiple cell lineages. Presently, bone marrow is considered as a prime source of MSCs; however, there are some drawbacks and limitations in use of these MSCs for cell therapy. In this study, we demonstrate that human gingival tissue-derived MSCs have several advantages over bone marrow-derived MSCs. Gingival MSCs are easy to isolate, homogenous and proliferate faster than bone marrow MSCs without any growth factor. Importantly, gingival MSCs display stable morphology and do not loose MSC characteristic at higher passages. In addition, gingival MSCs maintain normal karyotype and telomerase activity in long-term cultures, and are not tumorigenic. Thus, we reveal that human gingiva is a better source of MSCs than bone marrow, and large number of functionally competent clinical grade MSCs can be generated in short duration for cell therapy in regenerative medicine and tissue engineering.

The association of transforming growth factor (TGF)-β1 29C/T gene polymorphisms with level of tissue breakdown and periodontal disease progression is not clear. In this study, quantitative parameters of interdental papilla are investigated in patients with chronic periodontitis (CP) and TGF-β1 29C/T gene polymorphisms. Sixty gingiva samples were included. After determination of TGF-β1 29C/T gene polymorphisms using tetra-primer amplification refractory mutation system/polymerase chain reaction (T-ARMS-PCR), 15 gingival tissue samples from patients with CP in each genotype (TT, TC, and CC) were considered as case groups. Fifteen control samples were also collected from healthy individuals. After tissue processing, interdental gingiva tissues were exhaustively sectioned into 4-μm-thick sections. Ten to 13 sections were sampled by systematic uniform random sampling and stained with Masson trichrome, and the volume density (Vv) of the gingival components was estimated using Cavalieri estimation. Statistically significant differences were found in Vv of epithelium, connective tissue, collagenous and non-collagenous matrix, and blood vessels between control and CP groups (P <0.0001). There was a corresponding decrease in the collagenous matrix Vv in patients with the TT genotype compared with those with CT and CC genotypes. Collagenous matrix and blood vessel Vv values were statistically correlated with the number of T alleles (r = -0.74, r(2) = 54.8%, P = 0.0001 and r = 0.84, r(2) = 70.6%, P = 0.0001, respectively). This study shows that there is a strong association between TGF-β1 29C/T gene polymorphisms and quantitative parameters of interdental papilla in patients with CP.

There is evidence in the literature that adverse early attachment experiences and subsequent attachment insecurities during adulthood would lead to pessimism, low self-esteem, hopelessness and, ultimately, to suicide risk. This paper aims to review finding on the link between attachment style and suicidality. We searched the literature using the database of the U.S. National Center for Biotechnology Information (NCBI)-MedLine/Pubmed system from January 1992 until December 2016. We started with 1992 because, as far as we know, there are no published studies exploring the relationship between suicide and insecure attachment before that year. We considered reports published on the relationship between attachment style and suicidality. We applied several combinations of the following search terms: attachment, adult attachment style and suicidality, suicide, suicidal ideation, suicidal behavior or suicidal thoughts, and suicide attempts. We selected only English language studies. Research suggests that insecure attachment style, mostly anxious, and unresolved traumas are associated with an increased suicide risk. Few studies prospectively examined clinical course, comorbid psychiatric disorders, familial suicidality or other psychosocial factors. Further research is needed to highlight the nature of the link between attachment and suicidality. The presence of suicidal ideation and attempts might be a consequence of an underlying interaction between the emergence of psychiatrics symptoms, and the long-lasting presence of inadequate patterns of attachment. Within this context, Separation Anxiety Disorder, categorized in the DSM-5 as a condition not confined to childhood but as an anxiety disorder that may occur through the entire lifespan, might be the a key for the comprehension of this link. From a neurobiological point of view, the role of oxytocin remains unclear.

Anterior cruciate ligament (ACL) injuries are common, especially in young individuals who participate in sports activities associated with pivoting, decelerating and jumping. About 70% of ACL injuries do not result from direct contact. Establishing risk factors is important for prevention strategies. Risk factors for ACL injuries include environmental factors (e.g. high level of friction between shoes and the playing surface) and anatomical factors (e.g. narrow femoral intercondylar notch and increased joint laxity). History taking and physical examination provide the basis for diagnosis. Magnetic resonance imaging (MRI) is highly sensitive and specific and provides information about associated injuries such as meniscal tears. ACL-injury leads to knee instability which is associated with both acute dysfunction and long-term degenerative changes, such as osteoarthritis and meniscal damage. Surgical treatment of ACL-tears is effective in regard to short term rehabilitation but does not necessarily alter the natural course of this injury and its long-term complications. Therefore, surgical treatment should be reserved primarily for young individuals and for those who are high risk for ACL injury. ACL reconstruction is the standard surgery; however, a wide variety of reconstruction procedures is available and a gold standard procedure has not been defined. Nevertheless, arthroscopic reconstruction with either bone-patellar tendon-bone or a hamstring tendon graft is the most widely used method. Surgical timing is important. Early surgical intervention (i.e. within 4 weeks of injury) might increase complications.

Tie-2, angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), ephrin-B2 and Eph-B4 are all important vascular morphogenesis factors which exhibit their functions in angiogenesis and blood vessel remodeling in embryonic stage. However, their roles in post-natal inflammatory angiogenesis are still unclear. Pyogenic granuloma is a benign inflammatory lesion that mostly occurs on the gingiva of females with high levels of steroid hormones. Prominent capillary growth in hyperplastic granulation tissue is characteristic histopathologically in pyogenic granuloma. The purpose of this study was to detect and compare the expressions of Tie-2, Ang-1, Ang-2, ephrin-B2 and Eph-B4 among pyogenic granuloma on human gingiva, gingiva diagnosed with periodontitis and healthy gingiva by immunohistochemistry. The immunostaining revealed that all of the endothelial cells and some mesenchymal cells expressed Tie-2. The cells which expressed Ang-1 and Ang-2 were mainly macrophage- or monocyte-like mesenchymal cells and smooth muscle cells surrounding blood vessels. The expression of ephrin-B2 and Eph-B4 was not exclusively limited to the endothelial cells of arteries and veins, respectively, as in mice embryo. Eph-B4 was expressed in the endothelial cells of newly budding capillaries and venules while ephrin-B2 was expressed in macrophage-like mesenchymal cells. Some of the ephrin-B2 positive cells were in direct contact with endothelial cells. The statistical analysis demonstrated that all of the five factors were upregulated in pyogenic granuloma compared to healthy gingiva. In conclusion, the 5 polypeptides mentioned above may play important roles in the process of adult inflammatory neovascularization, especially in pyogenic granuloma. It is highly plausible that most of the new capillaries in inflammatory angiogenesis originated from venules instead of arterioles.

Medicinal leeches use their suction discs for locomotion, adhesion to the host and, in the case of the anterior disc, also for blood ingestion. The biomechanics of their suction-based adhesion systems has been little understood until now. We investigated the functional morphology of the anterior and posterior suckers of Hirudo verbana by using light and scanning electron microscopy. Furthermore, we analysed the adhesion qualitatively and quantitatively by conducting behavioural and mechanical experiments. Our high-speed video analyses provide new insights into the attachment and detachment processes and we present a detailed description of the leech locomotion cycle. Pull-off force measurements of the anterior and posterior suction organs on seven different substrates under both aerial and water-submersed conditions reveal a significant influence of the surrounding medium, the substrate surface roughness and the tested organ on attachment forces and tenacities.

This paper examines the relations between self-reported attachment orientation at work and personality, self-esteem, trait emotional intelligence (aka emotional self-efficacy), and independently assessed career potential and job performance. Self-report data were collected from 211 managers in an international business in the hospitality industry; independent assessments of these managers' job performance and career potential were separately obtained from the organization. A self-report measure of romantic attachment was adapted for application in the work context; a two-factor solution was found for this measure. Secure/autonomous attachment orientation at work was positively related to self-esteem, trait emotional intelligence, extraversion, agreeableness, and conscientiousness, and also to job performance. Not only was secure/autonomous attachment orientation at work statistically predictive of job performance, but the new measure also made a distinct contribution, beyond conscientiousness, to this prediction.
This article discusses Bowlby's development of an ethological-evolutionary perspective, and its implications for psychotherapy with adults. According to Bowlby, attachment behavior is instinctive, having emerged throughout the course of evolution to ensure protection and actual survival. Because the environment affects how attachment behavior unfolds, adverse experiences can divert developmental pathways away from resilience, toward dysfunction and emotional distress. Psychotherapy offers the experience of an attachment relationship. Part of the process involves helping patients understand that feelings such as fear and anxiety are inherent responses to safeguard affectional relationships when they are endangered. As working models are re-appraised and revised, there is emphasis on clarifying the attachment experiences that may have intensified these natural feelings.

Americans have increasingly turned to international adoption (IA) as an alternative way to build a family. Unfortunately, IA families are often being developed under conditions of loss, and sometimes these families struggle to form healthy attachments to each other. Disordered attachment (the failure to form a reciprocal, loving bond between parent and child) can occur, and can have devastating consequences. In some instances, IA children have been relinquished into state foster care systems; other families simply struggle for years caring for a developmentally delayed child who appears to have no emotion for his/her adoptive family. Nurses are likely to have contact with IA families and can use their education about attachment and bonding to help facilitate attachment in these developing families. Swanson's caring theory provides a clinically useful guide to meet this need.

Anterior cruciate ligament reconstruction (ACLR) provides an established surgical intervention to control pathological tibiofemoral translational and rotational movement. ACLR is a safe and reproducible intervention, but there remains an underlying rate of failure to return to preinjury sporting activity levels. Postoperative pathological laxity and graft reinjury remain concerns. Previously, unrecognized meniscal lesions, disruption of the lateral capsule, and extracapsular structures offer potential avenues to treat and to therefore improve kinematic outcome and functional results, following reconstruction. Addressing laterally based injuries may also improve the durability of intraarticular ACLR. Improving the anterior cruciate ligament (ACL) graft replication of the normal ACL attachment points on the femur and the tibia, using either double bundle or anatomical single bundle techniques, improves kinematics, which may benefit outcome and functionality, following reconstruction.

Full Text Available Emotional memories, and especially intrusive memories, are a common feature of many psychological disorders, and are overconsolidated by stress. Attachment theory posits that activation of mental representations of attachment figures can reduce stress and boost coping. This study tested the proposition that attachment activation would reduce consolidation of emotional and intrusive memories. Sixty-seven undergraduate students viewed subliminal presentations of traumatic and neutral images, which were preceded by subliminal presentations of either attachment-related images or non-attachment-related images; free recall and intrusive memories were assessed two days later. Participants with low avoidant attachment tendencies who received the attachment primes recalled fewer memories and reported fewer intrusions than those who received the non-attachment primes. Unexpectedly, those with high anxious attachment tendencies reported fewer memories. These findings generally accord with attachment theory, and suggest that consolidation of emotional memories can be moderated by activation of attachment representations.

In the present work, the relationship between attachment and exploration in adulthood is examined from both theoretical and empirical standpoints. Theoretically, attachment theory's exploration system is linked to R. W. White's (1959) concept of effectance motivation, and to the motive and goals constructs that are central to the achievement motivation literature. Empirically, 4 studies are presented that document a link between adult attachment (operationalized using categorical, continuous, and dimensional measures) and achievement motives (need for achievement and fear of failure) and achievement goals (mastery-approach, mastery-avoidance, performance-approach, performance-avoidance, and approach relative to avoidance personal strivings). Mediational analyses establish the role of challenge construal, threat construal, and competence valuation in accounting for the observed relationships.

Remora fishes adhere to, and maintain long-term, reversible attachment with, surfaces of varying roughness and compliance under wetted high-shear conditions using an adhesive disc that evolved from the dorsal fin spines typical of other fishes. Evolution of this complex hierarchical structure required extensive reorganization of the skull and fin spines, but the functional role of the soft tissues of the disc are poorly understood. Here I show that remora cranial veins are highly-modified in comparison to those of other vertebrates; they are transposed anteriorly and enlarged, and lie directly ventral to the disc on the dorsum of the cranium. Ancestrally, these veins lie inside the neurocranium, in the dura ventral to the brain, and return blood from the eyes, nares, and brain to the heart. Repositioning of these vessels to lie in contact with the ventral surface of the disc lamellae implies functional importance associated with the adhesive mechanism. The position of the anterior cardinal sinus suggests that it may aid in pressurization equilibrium during attachment by acting as a hydraulic differential.
Full Text Available Introduction. Deep anterior lamellar keratoplasty (DALK is intended for the surgical treatment of corneal pathology without the involvement of the endothelium. Sparing of the healthy host endothelium for lifetime is of utmost importance in young patients. Therefore, keratoconus is among the main indications for DALK. Outline of Cases. Two men, 22 and 28 years of age, underwent DALK for the treatment of progressive keratoconus, with low visual acuity, impossible to be corrected with gas-permeable contact lenses, due to the extreme conical protrusion of the cornea. Baring of Descemet’s membrane was achieved with lamellar dissection and peeling off the stroma. An 8.5 mm graft without the endothelium was sutured into an 8.0 mm bed. Both grafts remained clear and attached, without either ocular surface pathology or problems arising from sutures. The best corrected visual acuity was 20/25 and 20/40, with the astigmatism of 2.5 and 3.0 diopters, respectively. The follow-up was one year. Conclusion. This is the first presentation of DALK in our literature. The restoration of corneal transparency and stability, with sparing of the host endothelium, has put DALK among successful corneal tranplantation procedures. Together with Descemet stripping endothelial keratoplasty, which already accounts for almost a half of all our keratoplasties, it offers an alternative to penetrating keratoplasty.
Full Text Available Orthodontic appliances modify the local environment of the oral cavity, increase the accumulation of dental plaque, and affect the condition of the gingiva. The aim of this study is assessment of Brazilian propolis toothpaste’s effect on plaque index (PLI and gingival index (GI in patients with CL/CLP treated using orthodontic appliances in the 35-day study period. The study population included 96 patients of an Orthodontic Outpatient Clinic, ACSiMS in Bytom. All the patients participated in the active phase of orthodontic treatment using buccal multibracket appliances or removable appliances. During the first examination, each patient was randomly qualified to the propolis group or control group. A statistically significant decrease in GI and PLI in the entire propolis group (P<0.01 was shown during repeated examination. Insignificant change in GI was in the entire control group during the repeated examination compared to the baseline. Similar result was obtained in patients treated with multibracket and removable appliances. The orthodontic appliance type did not affect the final dental plaque amount and gingival condition in patients using the propolis toothpaste. These results may be clinically useful to improve prevention and control oral infectious diseases during orthodontic treatment patients with oral cleft.
Full Text Available Since the discovery of bone marrow mesenchymal stem cells (BMMSCs, many researchers have focused their attention on new sources of mesenchymal stem cells (MSCs. Consequently, MSCs that display self-renewal capacity, multidifferentiation potential and immunomodulatory properties have been isolated from human oral tissues, including tooth, periodontal ligament, and gingiva. Oral MSCs involve dental pulp stem cells (DPSCs, stem cells from exfoliated deciduous teeth (SHED, periodontal ligament stem cells (PDLSCs, dental follicle stem cells (DFCs, stem cells from apical papilla (SCAP and gingival stem cells (GMSCs. Current research on oral stem cells is expanding at an unprecedented rate. That being the case, a plethora of in vitro differentiation assays, immunodeficient animal transplantations and preclinical trials have demonstrated that these cells exhibit strong potential for both regenerative dentistry and medicine. Oral MSCs have proved their capability to repair cornea, dental pulp, periodontal, bone, cartilage, tendon, neural, muscle and endothelial tissues without neoplasm formation as well as to treat inflammatory diseases and immune disorders. This article describes the current understanding of oral MSCs and their prospective applications in cell-based therapy, tissue engineering and regenerative medicine. Special attention is placed on GMSCs as they are easily accessible and may be obtained in a convenient and minimally invasive way.

Resin-bonded extracoronal attachments may be indicated for the abutment teeth of removable partial dentures, especially for anterior teeth when a cingulum rest must be provided. This type of treatment has a series of advantages such as minimal tooth reduction, supragingival margins, favourable stress distribution, and improved aesthetic appearance. To report a clinical case of oral rehabilitation using a combination of resin-bonded extracoronal attachments joined by a Dolder bar with a removable partial denture. A 60-year-old male patient with only the canines in the maxillary arch was restored with a combination of resin-bonded extracoronal attachments joined by a Dolder bar and a removable partial denture. Dentures with resin-bonded extracoronal attachments can have a number of advantages over traditional clasp-retained removable partial dentures. © 2009 The Authors.

This study investigated links between parent characteristics and daughters' attachment styles for 90 female undergraduates and their married biological parents. Parents with a secure attachment pattern were rated as more accepting, less controlling, more competent, and more consistent in showing love and affection to their daughter in contrast to parents with an insecure attachment pattern. Significant positive associations were found between mothers' fearful attachment scores and the fearful, preoccupied, and dismissive attachment scores of daughters. Daughters of matched secure parents were more likely to report a secure attachment style, while daughters of matched insecure parents were more likely to report an insecure attachment style.

This paper reports and analyses 20 keratoplasties with or without anterior segment reconstruction carried out for penetrating injuries of the anterior segment. The results show that 80% clear grafts were achieved and 65% of eyes had vision restored to 6/18 or better. No eyes were lost. The complications were retinal detachments 2 cases, corneal graft rejection 2 cases, glaucoma 4 cases (2 mild and easily controlled) and one each of amblyopia and retinal folds through macular area. Eyes that have "quietened" following severe penetrating injuries of the anterior segment should be considered for penetrating keratoplasty and anterior segment reconstruction if they retain normal intraocular pressures and have vision of at least accurate projection of light in all quadrants. As well as achieving clear grafts and improvement of vision as above, all eyes had better cosmetic appearance. Two eyes had an ipsilateral rotational autokeratoplasty. This technique has a role to play when central scarring can be rotated to the periphery if sufficient undamaged cornea remains and interference with angle structures can be minimised.

Tooth wear is defined as the progressive loss of a tooth's surface due to actions other than those which cause tooth decay or dental trauma. It is a pathological condition with an increasing prevalence among young people. The aim of this article is to describe an alternative treatment modality to rehabilitate the anterior guidance by a minimally invasive interdisciplinary ortho-restorative treatment. Two patients came to the dental clinic for restorative treatment in order to rehabilitate the worn anterior dentition. Clinical analysis showed tooth surface loss located at the incisal edges by attrition due to an inadequate anterior guidance. In both cases the occlusal vertical dimension was reduced. First, following Dahl's principle, resin attachments were placed in the upper canines. These attachments allowed the extrusion of posterior teeth in order to increase the occlusal vertical dimension. Furthermore, anterior teeth were intruded in order to create space for the restorative material. In the second phase, the restorative treatment was completed. Due to the characteristics of the case, feldspathic ceramic veneers were indicated. A diagnostic wax-up was performed to assist the treatment planning and a mock-up was prepared. Then, maxillary incisors were prepared through the mock-up to ensure a minimally invasive technique. Afterwards, silicone impressions were taken. Finally, veneers were cemented with a light-cured cement. In the present case, the functional and aesthetic parameters required by the patients were achieved, thus satisfying their needs. Key words: Tooth wear, anterior guidance, feldspathic veneers, Dahl's principle, minimally invasive.

Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

Greater anterior knee laxity (AKL) has been identified as an anterior cruciate ligament (ACL) injury risk factor. The structural factors that contribute to greater AKL are not fully understood but may include the ACL and bone geometry. To determine the relationship of ACL width and femoral notch angle to AKL. Cross-sectional study. Controlled laboratory. Twenty recreationally active females (age = 21.2 ± 3.1 years, height = 1.66.1 ± 7.3 cm, mass = 66.5 ± 12.0 kg). Anterior cruciate ligament width and femoral notch angle were obtained with magnetic resonance imaging of the knee and AKL was assessed. Anterior cruciate ligament width was measured as the width of a line that transected the ACL and was drawn perpendicular to the Blumensaat line. Femoral notch angle was formed by the intersection of the line parallel to the posterior cortex of the femur and the Blumensaat line. Anterior knee laxity was the anterior displacement of the tibia relative to the femur (mm) at 130 N of an applied force. Ten participants' magnetic resonance imaging data were assessed on 2 occasions to establish intratester reliability and precision. Using stepwise backward linear regression, we examined the extent to which ACL width, femoral notch angle, and weight were associated with AKL. Strong measurement consistency and precision (intraclass correlation coefficient [2,1] ± SEM) were established for ACL width (0.98 ± 0.3 mm) and femoral notch angle (0.97° ± 1.1°). The regression demonstrated that ACL width (5.9 ± 1.4 mm) was negatively associated with AKL (7.2 ± 2.0 mm; R(2) = 0.22, P = .04). Femoral notch angle and weight were not retained in the final model. A narrower ACL was associated with greater AKL. This finding may inform the development of ACL injury-prevention programs that include components designed to increase ACL size or strength (or both). Future authors should establish which other factors contribute to greater AKL in order to best inform injury-prevention efforts.

The aim of this study was to compare the retention of mini implant overdenture by the number, the type of magnetic attachment, and the directions of applied dislodging force. The experimental groups were designed by the number and type of magnetic attachment. Twenty samples were tested with Magden implants. Each attachment was composed of the magnet assembly in overdenture sample and the abutment keeper in a mandibular model. Dislodging forces were applied to the overdenture samples (50.0 mm/min) in 3 directions. The loading was repeated 10 times in each direction. The values of dislodging force were analyzed statistically using SPSS at 95% level of confidence. The retentive force of group 2 was greater than that of group 1 in both types of attachment in every direction (P type magnetic attachment was higher than that of cushion type attachment in both groups (P types (P types of attachment showed the lowest retentive force with anteriorposterior direction of dislodging force (P type of magnetic attachment. In both types of magnetic attachment, the greater retentive force was attained with more implants. Oblique retentive force of flat type magnetic attachment was greater than that of cushion type. Among all subgroups, anterior-posterior retentive force was the lowest among three different directions of dislodging force.

The serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented. Orientation and size of each fascicle were measured and the physiological cross-sectional area (PCSA) calculated. Three subdivisions of the serratus anterior were identified. A new finding was the discovery of two distinctive fascicles attached to the superior and inferior aspects of rib 2. The rib 2 inferior fascicle had the largest PCSA (mean 1.6 cm 2 ) and attached, with the rib 3 fascicle, along the medial border of the scapula to form the middle division. The rib 2 superior and rib 1 fascicles attached to the superior angle of the scapula (upper division). Fascicles from ribs 4-8/9 attached to the inferior angle of the scapula (lower division). Mean fascicle angle relative to a vertical midline reference and PCSA for each division were 29° and 1.3 cm 2 (upper), 90° and 2.2 cm 2 (middle) and 59° and 3.0 cm 2 (lower). This novel study demonstrated the presence of morphologically distinct serratus anterior subdivisions. The results of this study will inform the development of optimal techniques for the assessment, treatment and rehabilitation of this architecturally complex muscle in shoulder and neck pain.

Numerous studies investigated the reasons for premature osteoarthritis due to partial meniscectomy (PM). However, the influence of meniscectomy on attachment forces and superficial strain of the tibial meniscus is unclear. It is hypothesised that these parameters depend on the degree of PM. Six porcine medial menisci were placed in a custom made apparatus, and each meniscal attachment was connected to a force sensor. After printing markers onto the tibial meniscal surfaces, the menisci were positioned on a glass plate enabling optical superficial strain measurement. Additionally, contact area and pressure were investigated. Each meniscus was axially loaded up to 650 N using its respective femoral condyle. Testing was conducted intact and after 50 and 75% PM of the posterior horn and extending 75% PM to the anterior horn. With increasing meniscectomy, the attachment forces decreased anteriorly by up to 17% (n.s.) and posteriorly by up to 55% (p = 0.003). The circumferential strain in the peripheral meniscal zones was not affected by the meniscectomy, while in some meniscal zones the radial strain changed from compression to tension. Contact area decreased by up to 23% (p = 0.01), resulting in an increase in 40% (p = 0.02) for the maximum contact pressure. Partial meniscectomy significantly alters the loading situation of the meniscus and its attachments. Specifically, the attachment forces decreased with increasing amount of meniscal tissue loss, which reflects the impaired ability of the meniscus to transform axial joint load into meniscal hoop stress.

To categorize and summarize up-to-date anterior cruciate ligament (ACL) research published in Arthroscopy and The American Journal of Sports Medicine and systematically review each subcategory, beginning with ACL anatomy. After searching for "anterior cruciate ligament" OR "ACL" in Arthroscopy and The American Journal of Sports Medicine from January 2012 through December 2014, we excluded articles more pertinent to ACL augmentation; open growth plates; and meniscal, chondral, or multiligamentous pathology. Studies were subcategorized for data extraction. We included 212 studies that were classified into 8 categories: anatomy; basic science and biomechanics; tunnel position; graft selection; graft fixation; injury risk and rehabilitation; practice patterns and outcomes; and complications. Anatomic risk factors for ACL injury and post-reconstruction graft failure include a narrow intercondylar notch, low native ACL volume, and increased posterior slope. Regarding anatomic footprints, the femoral attachment is 43% of the proximal-to-distal lateral femoral condylar length whereas the posterior border of the tendon is 2.5 mm from the articular margin. The tibial attachment of the ACL is two-fifths of the medial-to-lateral interspinous distance and 15 mm anterior to the posterior cruciate ligament. Anatomic research using radiology and computed tomography to evaluate ACL graft placement shows poor interobserver and intraobserver reliability. With a mind to improving outcomes, surgeons should be aware of anatomic risk factors (stenotic femoral notch, low ligament volume, and increased posterior slope) for ACL graft failure, have a precise understanding of arthroscopic landmarks identifying femoral and tibial footprint locations, and understand that imaging to evaluate graft placement is unreliable.

Full Text Available Background. Chondrosarcomas represent approximately 30% of primary malignant bone tumors, the most frequent of which is on anterior thoracic wall. Case report. We presented a case of 50-year-old man suffering from a slowgrowing, painless giant chondrosarcoma of the anterior chest wall. A wide resection was performed to excise the tumor including attached skin, right breast, ribs, sternum, soft tissues and parietal pleura. Mediastinum was not affected by the tumor. After resecting a 26 × 20 × 22 cm segment, the chest wall defect was reconstructed with a Marlex mesh and extensive latissimus dorsi myocutaneous flap pedicled on the right thoracodorsal vessels. Histopatology diagnosis was chondrosarcoma G 2−3. The mechanics of ventilation was not altered and respiratory function was normal from the immediate postoperative period. Three years after the operation postoperative results showed no local recurrence and excellent functional and aesthetic results were evident. Respiratory function remained unaltered. Conclusion. According to the results it can be concluded that the use of Marlex mash and myocutaneous flap is good method for stabilization of the chest wall and enough to avoid paradoxical respiratory movements in managing giant chondrosarcoma of the anterior chest wall.

Pathologic tooth migration related to periodontal disease is a common chief complaint of periodontal patients. This paper describes the treatment of a case of severe periodontal disease and disfiguring pathologic migration of maxillary central incisors, which required a multidisciplinary approach. After conventional periodontal treatment was performed, the anterior diastema was closed using a combination of orthodontic therapy and restorative treatment. A 6-month follow-up examination of this case revealed resolution of the anterior pathologic migration, with gains in clinical attachment levels and a successful esthetic and functional final result.

Intimate relationships can both affect and be affected by trauma and its sequelae. This special issue highlights research on trauma, attachment, and intimate relationships. Several themes emerged. One theme is the exploration of the associations between a history of trauma and relational variables, with an emphasis on models using these variables as mediators. Given the significance of secure attachment for healthy relationships, it is not surprising that attachment emerges as another theme of this issue. Moreover, a key component of relationships is trust, and so a further theme of this issue is betrayal trauma (J. J. Freyd, 1996 ). As the work included in this special issue makes clear, intimate relationships of all types are important for the psychological health of those exposed to traumatic events. In order to best help trauma survivors and those close to them, it is imperative that research exploring these issues be presented to research communities, clinical practitioners, and the public in general. This special issue serves as one step toward that objective.

To analyze the possible association between magnetic resonance imaging signal intensity of temporomandibular joint disk and posterior attachment, and the type and extent of disk displacement, disk donfiguration, effusion and clinical signs in patients with internal derangement. Magnetic resonance images of the 132 temporomandibular joints of 66 patients with temporomandibular joint displacement were analyzed. The clinical findings were obtained by retrospective review of the patients' records. The type and extent of disk displacement, disk configuration and effusion were evaluated on the proton density MR images. The signal intensity from the anterior band, posterior band and posterior attachment were measured on MR images. The associations between the type and extent of disk displacement, disk configuration, effusion and clinical signs and the MR signal intensity of disk and posterior attachment were statistically analyzed by student's t-test. Of 132 joints, 87 (65.9%) showed anterior disk displacement with reduction (ADR) and 45 (34.1%) showed anterior disk displacement without reduction (ADnR). This signals from posterior attachments were lower in joints with ADnR than those of ADR (p<0.05). The results showed statistically significant (p<0.05) association between the type and extent of disk displacement and disk configuration, and decreased signal intensity of posterior attachment. There were no statistical associations between pain, noise and limited mouth opening, and signal intensity of disk and posterior attachment. The average signal from posterior attachment was lower in joints with ADnR than that of ADR. The type and extent of disk displacement and disk configuration appeared to be correlated with the signal intensity from posterior attachment.

Attachment is a key subfield in the area of parenting and parent-child relationships research. In this brief overview, we summarise what we consider to be the state-of-the-art of attachment research, focusing primarily on the nature and significance of attachment in infancy and early childhood. We review 4 major topics that are central issues in the scientific literature on attachment: (1) the role of the environment in the development of attachment, (2) the intergenerational transmission of patterns of attachment, (3) the stability of attachment patterns through early adulthood, and (4) the role of attachment in adjustment and maladjustment. We conclude by highlighting several critical unresolved issues and priorities for future research. Copyright © 2017. Published by Elsevier Ltd.

Vertices of an affiliation network are linked to attributes and two vertices are declared adjacent whenever they share a common attribute. For example, two customers of an internet shop (or video-sharing website) are called adjacent if they have purchased (or downloaded) the same or similar items. Assuming that each newly arrived customer is linked preferentially to already popular items we obtain a preferred attachment affiliation network that evolves in time. We show that the fraction of customers having neighbours scales as for large . Here is the ratio between the two intensities: intensity of the flow of customers and that of the newly arriving items.

Full Text Available This article describes a case of gingival asymmetry with compromising aesthetics. A 25-year-old dental student presented to the department of prosthetic dentistry. She was concerned about the greyish transparency of the crown metal margin through the marginal gingiva. The crown was placed to restore her lateral incisor. A comprehensive examination revealed that this unaesthetic aspect was caused by a non-harmonious gingival architecture in the lateral incisor marked by an unaesthetic gingival Zenith. The treatment plan included a surgical crown lengthening followed by prosthetic therapy consisting in a Zirconia based crown replacing the old prosthesis. Thanks to a well-planned multi-disciplinary approach, the result was esthetically acceptable and the patient was satisfied.
Divorce is becoming increasingly widespread in Europe. In this study, I present an analysis of the role played by attachment style (secure, dismissing, preoccupied and fearful, plus the dimensions of anxiety and avoidance) in the adaptation to divorce. Participants comprised divorced parents (N = 40) from a medium-sized city in the Basque Country. The results reveal a lower proportion of people with secure attachment in the sample group of divorcees. Attachment style and dependence (emotional and instrumental) are closely related. I have also found associations between measures that showed a poor adjustment to divorce and the preoccupied and fearful attachment styles. Adjustment is related to a dismissing attachment style and to the avoidance dimension. Multiple regression analysis confirmed that secure attachment and the avoidance dimension predict adjustment to divorce and positive affectivity while preoccupied attachment and the anxiety dimension predicted negative affectivity. Implications for research and interventions with divorcees are discussed.

Despite requiring dental crown preparation and possible root canal treatment, besides the difficulty of clinical and laboratory repairs, and financial burden, the association between fixed (FPD) and removable partial dentures (RPD) by means of attachments is an important alternative for oral rehabilitation, particularly when the use of dental implants and FPDs is limited or not indicated. Among the advantages of attachment-retained RPDs are the improvements in esthetics and biomechanics, as well as correction of the buccal arrangement of anterior teeth in Kennedy Class III partially edentulous arches.

Brain areas critical for stereopsis have been investigated in non-human primates but are largely unknown in the human brain. Microelectrode recordings and functional MRI (fMRI) studies in monkeys have shown that in monkeys the inferior temporal cortex is critically involved in 3D shape categorization. Furthermore, some human fMRI studies similarly suggest an involvement of visual areas in the temporal lobe in depth perception. We aimed to investigate the role of the human anterior temporal neocortex in stereopsis by assessing stereoscopic depth perception before and after anterior temporal lobectomy. Eighteen epilepsy surgery patients were tested, pre- and postoperatively, in 3 different depth discrimination tasks. Sensitivity for local and global disparity was tested in a near-far discrimination task and sensitivity for 3D curvature was assessed in a convex-concave discrimination task, where 3D shapes were presented at different positions in depth. We found no evidence that temporal lobe epilepsy surgery has a significant effect on stereopsis. In contrast with earlier findings, we conclude that local as well as global stereopsis is maintained after unilateral resection of the temporal pole in epilepsy surgery patients. Our findings, together with previous studies, suggest that in humans more posterior visual regions underlie depth perception. Copyright © 2016 Elsevier Ltd. All rights reserved.
Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

Objective The establishment of an accurate understanding of one's social context is a central developmental task during adolescence. A critical component of such development is to learn how to integrate the objective evaluation of one's behavior with the social response to the latter—here referred to as social feedback processing. Case report We measured brain activity by means of fMRI in 33 healthy adolescents (12–19 years old, 14 females). Participants played a difficult perceptual game with integrated verbal and visual feedback. Verbal feedback provided the participants with objective performance evaluation (won vs. lost). Visual feedback consisted of either smiling or angry faces, representing positive or negative social evaluations. Together, the combination of verbal and visual feedback gave rise to congruent versus incongruent social feedback combinations. In addition to assessing sex differences, we further tested for the effects of age and attachment style on social feedback processing. Results revealed that brain activity during social feedback processing was significantly modulated by sex, age, and attachment style in prefrontal cortical areas, ventral anterior cingulate cortex, anterior insula, caudate, and amygdala/hippocampus. We found indication for heightened activity during incongruent social feedback processing in females, older participants, and individuals with an anxious attachment style. Conversely, we observed stronger activity during processing of congruent social feedback in males and participants with an avoidant attachment style. Conclusion Our findings not only extend knowledge on the typical development of socio-emotional brain function during adolescence, but also provide first clues on how attachment insecurities, and particularly attachment avoidance, could interfere with the latter mechanisms.

Different clinical parameters have been advocated as potential predictors of alveolar and basal jawbone morphology. The aim of this study is to describe, by tomographic means, alveolar and basal osseous dimensions of the anterior mandible in healthy individuals and evaluate potential correlations with biotype, along with other clinical parameters. One hundred consecutive healthy patients needing surgery in the posterior mandible were enrolled in this observational study (group 1 = 50 patients with thin biotype; group 2 = 50 patients with thick biotype). Data were collected for: 1) Little irregularity index for anterior crowding; 2) molar and canine class relationship; 3) previous orthodontic treatment; 4) gingival recession; and 5) band of keratinized gingiva for each of the six anterior mandibular teeth (#22 through #27). At the most mid-buccal computerized tomography slice of each tooth, other parameters were measured, including: 1) distance from the cemento-enamel junction to the bone crest; 2) tooth torque (TT); 3) labial cortical bone thickness (BT) for alveolar and basal bone; and 4) BT 5 and 10 mm apical to the tooth apex. Data were statistically analyzed, and significance was set at P ≤0.05. Mean thickness of alveolar bone ranged from 6.66 to 4.51 mm (standard deviation [SD] = 1.46 for tooth #27; SD = 1.01 for tooth #25) whereas mean thickness of basal bone ranged from 8.9 to 8.2 mm (SD = 2.06 for tooth #22; SD = 2.06 for tooth #26). Mean thickness of bone at 5 mm from apex ranged from 11.94 to 10.47 mm (SD = 2.96 for tooth #25; SD = 2.22 for tooth #22), whereas mean thickness of bone at 10 mm from apex ranged from 13.75 to 11.08 mm (SD = 2.79 for tooth #25; SD = 2.53 for tooth #27). No statistically significant differences were detected among biotypes, whereas: 1) TT, 2) age, and 3) smoking habit were often predictors of reduction in BT in a multiple linear regression model. Male sex was often a predictor of positive changes in BT, and previous

The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We report a case of incidentally discovered anterior cruciate ligament calcification. We discuss the likely etiology and clinical implications of this finding.

The Spallation Neutron Source (SNS) diagnostic instruments at Oak Ridge National Laboratory are based on the Network Attached Device (NAD) concept. Each pickup or sensor has its own resources such as timing, data acquisition and processing. NADs are individually connected to the network, thus reducing the brittleness inherent in tightly coupled systems. This architecture allows an individual device to fail or to be serviced or removed without disrupting other devices. This paper describes our implementation of the nearly 400 NADs to be deployed. The hardware consists of rack-mounted PCs with standard motherboards and PCI data-acquisition boards. The software environment is based on LabVIEW and EPICS. LabVIEW supports the agile development demanded by modern diagnostic systems. EPICS is the control system standard for the entire SNS facility. To achieve high performance, LabVIEW and EPICS communicate through shared memory. SNS diagnostics are developed by a multi-laboratory partnership including ORNL, BNL, LAN...
Full Text Available Herniation of the anterior lens capsule is a rare abnormality in which the capsule bulges forward in the pupillary area. This herniation can be mistaken for an anterior lenticonus where both the capsule and the cortex bulge forward. The exact pathology behind this finding is still unclear. We report the clinical, ultrasound biomicroscopy (UBM and histopathological findings of a case of herniation of the anterior lens capsule. UBM helped to differentiate this entity from anterior lenticonus. Light microscopy revealed capsular splitting suggestive of capsular delamination and collection of fluid (aqueous in the area of herniation giving it a characteristic appearance.

For operative reconstruction, precise anatomic information on the dimensions of the ankle ligaments is important and can help to optimize these procedures. The purpose of this study was to investigate the length and width dimensions of the ankle ligaments and to contrast the results with the published literature. Seventeen non-paired adult, formalin-fixed ankle specimen were dissected to expose the capsuloligamentous structures. The following ligaments were investigated: tibiofibular syndesmosis (anterior and posterior tibiofibular ligament/ATiFL and PTiFL), lateral ankle ligaments (anterior and posterior talofibular ligament, calcaneofibular ligament/ATFL, PTFL and CFL), medial ankle ligaments (deltoid ligament, anterior and posterior tibiotalar ligament/ATTL and PTTL). After identification of the ligaments, the dimensions were measured with a ruler and a sliding caliper. Additionally, the attachment area and the center of insertion (COI) were evaluated. The dimensions of the ligaments were recorded. Measurements were calculated and discussed according to the existing literature. The tibial COI of the ATiFL was situated 8.35 ± 2.05 mm from the inferior articular surface of the tibia and 5.04 ± 1.32 mm from the fibular notch. Its fibular COI was situated 25.45 ± 5.84 mm from the tip of the lateral malleolus and 3.12 ± 1.01 mm from the malleolar articular surface. The calcaneal COI of the CFL was situated 20.63 ± 3.56 mm anterior and 5.73 ± 1.89 mm plantar to the superior edge of the calcaneal. Its fibular attachment of the CFL was directly at the tip of the lateral malleolus, dorsal to the fibular attachment of the ATFL. Studies of the therapeutic options in severe ankle ligament injuries have shown better results in anatomical reconstructions compared to other operative treatments. To optimize these procedures, exact anatomical information on the dimensions of the ankle ligaments should be beneficial.

A participant of the annual Hamburg marathon collapses on the finish line. Medics at the scene find a conscious patient and prepare transport to the finish area medical center. During transport the patient becomes unconscious and pulseless. The medics immediately perform basic life support and cardiopulmonary resuscitation (CPR). An automated external defibrillator (AED) is attached and after analysis of the patient}s heart rhythm the patient is defibrillated twice. The ambulance service reach the scene with a delay. The emergency physician}s ECG shows ventricular fibrillation (VF) and two more defibrillations are delivered. Return of spontaneous circulation can be achieved. After stabilisation the patient is taken to hospital by ambulance. The ECG shows an anterior myocardial infarction and right bundle-branch block. The coronary angioplasty (PTCA) shows single-vessel disease with complete stenosis of the proximal part of the anterior interventricular branch. Revasucarisation is successful and a coronary stent is applied. The patient survives neurologically intact. This case report demonstrates the importance of readily available AED and specially trained medics. By immediately using the AED this patient was defibrillated before the ambulance service and emergency physician arrived at the scene. Spontaneous circulation was restored.

Full Text Available Research of attachment is numerous and versatile. They differ according to problems addressed, methodology applied (longitudinal studies, studies with horizontal designs, different instruments used, different methods of data analysis, and characteristics of samples involved (concerning age socio/economic status, family ecology. The research is commonly relied on the core assumptions of the theory itself, and the shared characteristic is orientation to explore complex phenomena of human experience and functioning. From the vast variety of research only those who most directly test the basic assumptions of the attachment theory are focused and addressed in the paper: representation of patterns of attachment in the childhood and adulthood, stability and change of attachment security from infancy to early adulthood, transgenerational transmission of attachment characteristics, the place and the role of attachment behavioral system in the personality development. The aim of the paper is to highlight the basic research and theory issues and directions, and illustrate them with concrete research date.

A special type of repairable meniscal lesion involving the peripheral attachment of the posterior horn of the medial meniscus is commonly associated with anterior cruciate ligament deficiency and is termed a "ramp lesion." However, there are no previously published articles reporting the epidemiologic characteristics of ramp lesions. The ramp lesion is a special type of medial meniscal tear with high prevalence associated with anterior cruciate ligament rupture; the prevalence increases with time from anterior cruciate ligament injury. Age and gender are risk factors affecting the prevalence of the ramp lesion. Cross-sectional study; Level of evidence, 3. From April 2002 to October 2007, 868 consecutive knees were diagnosed as having an anterior cruciate ligament injury and received arthroscopic surgery for anterior cruciate ligament reconstruction. All the patients had verified tears of the ramp area under arthroscopy. The prevalence of the ramp lesion was evaluated retrospectively. Then, all cases were divided into different groups depending on the time interval from anterior cruciate ligament injury to anterior cruciate ligament reconstruction and other relevant risk factors such as age and gender. The effects of age, gender, and time from injury on the prevalence of ramp lesions were analyzed. Among 868 knees that underwent surgery for anterior cruciate ligament reconstruction, 144 knees were diagnosed as having a ramp lesion. The mean age was 24.7 years; there were 113 male and 31 female patients. The mean time from injury to anterior cruciate ligament reconstruction was 27.2 months. The prevalence of ramp lesions was 16.6%, which was analyzed as a logarithmic correlation with time from injury. Patients younger than 30 years of age and male patients had a significantly higher prevalence of ramp lesions. The ramp lesion is a common meniscal injury that can occur at the time of anterior cruciate ligament rupture or as a result of knee laxity associated with

Full Text Available The purpose of this retrospective study was to associate the amount of keratinized gingiva present in adolescents prior to orthodontic treatment to the development of gingival recessions after the end of treatment. The sample consisted of the intra-oral photographs and orthodontic study models from 209 Caucasian patients with a mean age of 11.20 ± 1.83 years on their initial records and 14.7 ± 1.8 years on their final records. Patients were either Angle Class I or II and were submitted to non-extraction orthodontic treatment. Gingival recession was evaluated by visual inspection of the lower incisors and canines as seen in the initial and final study models and intra-oral photographs. The amount of recession was quantified using a digital caliper and the observed post-treatment gingival margin alterations were classified as unaltered, coronal migration of the gingival margin or apical migration of the gingival margin. The width of the keratinized gingiva was measured from the mucogingival line to the gingival margin on the pre-treatment photographs. The teeth that developed gingival recession and those that did not have their gingival margin position changed did not differ in relation to the initial amount of keratinized gingiva (3.00 ± 0.61 and 3.5 ± 0.86 mm, respectively. Paradoxically, teeth that presented a coronal migration of the gingival margin had a smaller initial amount of keratinized gingiva (2.26 ± 0.31 mm. The mean amount of initial keratinized gingiva did not predispose lower incisors and canines to gingival recession.O objetivo deste estudo retrospectivo foi associar a quantidade de gengiva ceratinizada existente em adolescentes pré-tratamento ortodôntico e o desenvolvimento de recessões gengivais pós-tratamento ortodôntico.

This study aims to retain normal knee kinematics after knee replacement surgeries by reconstructing anterior cruciate ligament during total knee arthroplasty. We use computational simulation tools to establish four dynamic knee models, including normal knee model, posterior cruciate ligament retaining knee model, posterior cruciate ligament substituting knee model, and anterior cruciate ligament reconstructing knee model. Our proposed method utilizes magnetic resonance images to reconstruct solid bones and attachments of ligaments, and assemble femoral and tibial components according representative literatures and operational specifications. Dynamic data of axial tibial rotation and femoral translation from full-extension to 135 were measured for analyzing the motion of knee models. The computational simulation results show that comparing with the posterior cruciate ligament retained knee model and the posterior cruciate ligament substituted knee model, reconstructing anterior cruciate ligament improves the posterior movement of the lateral condyle, medial condyle and tibial internal rotation through a full range of flexion. The maximum posterior translations of the lateral condyle, medial condyle and tibial internal rotation of the anterior cruciate ligament reconstructed knee are 15.3 mm, 4.6 mm and 20.6 at 135 of flexion. Reconstructing anterior cruciate ligament in total knee arthroplasty has been approved to be an more efficient way of maintaining normal knee kinematics comparing to posterior cruciate ligament retained and posterior cruciate ligament substituted total knee arthroplasty.

Refugees can suffer many experiences that threaten their trust in others. Although models of refugee mental health have postulated that attachment securities may be damaged by refugee experiences, this has yet to be empirically tested. This study aimed to understand the relationship between the nature of traumatic experiences sustained by refugees and attachment styles. In a cross-sectional study, treatment-seeking refugees (N = 134) were assessed for traumatic exposure using the Harvard Trauma Questionnaire and Posttraumatic Diagnostic Scale. Attachment style was assessed using the Experiences in Close Relationship Scale. Whereas gender and severity of interpersonal traumatic events predicted avoidant attachment style (accounting for 11% of the variance), neither these factors nor non-interpersonal trauma predicted anxious attachment. Exposure to interpersonal traumatic events, including torture, is associated with enduring avoidant attachment tendencies in refugees. This finding accords with attachment theories that prior adverse interpersonal experiences can undermine secure attachment systems, and may promote avoidance of attachment seeking. This finding may point to an important process maintaining poor psychological health in refugees affected by interpersonal trauma. © The Royal Australian and New Zealand College of Psychiatrists 2016.
Full Text Available The article is an attempt to present holistically the key concepts of attachment theory rediscovered for its potentials. The presented concepts include: narrow definition of attachment, behavioral control system of attachment, attachment working model and patterns of attachment. The concepts are presented in the context of child attachment theory and adult attachment theory, in addition to description of the development of attachment. Concepts, as well as developmental processes are presented from the stand point of pioneers in this field (John Bowlby and Mary Ainsworth as well as from the standpoint of their successors (Everett Waters and Malcolm West. Compacted ness of the theory, possibilities for operationalization of its key concepts and its application to empirical studies of complex psychological issues that have never been scientifically explored, makes it a very prospective theory in view of possible integration of existing research findings and initiating new research and new practices in psychotherapy, social work and work in schools. The goal of this integral presentation of attachment theory is to highlight its benefits and possibilities for understanding and research complex field of human's psychosocial functioning.
Full Text Available Implant-supported overdentures provide a good opportunity for dentists to improve oral health and quality-of-life of patients. Atrophic mandible poses a significant challenge to successful oral rehabilitation with dental implants. In this article, the fabrication of lower overdenture by two narrow platform implants is described with dual retentive, resilient, self-locating locator attachment system. The locator attachment system has the lowest profile in comparison with the ball and bar attachments and is versatile up to 40 of divergence between two implants. By using locators as attachments, we can meet functional, economic and social expectation of patients with ease and satisfaction.

Full Text Available Introduction: Sprained ankle is a very common injury in children. Proper treatment of ligament injuries enables full recovery. X-ray and US examinations are commonly available diagnostic methods. Material and methods: Two hundred and six children (113 girls and 93 boys, mean age 10.6 with recent ankle joint sprain (up to 7 days of injury were subject to a retrospective analysis. All patients underwent an X-ray and US examination of the ankle joint within 7 days of injury. In 19 patients, anterior talofi bular ligament reconstruction was conducted. Results: X-ray failed to visualize a pathology in 129 children (63%; in 24 patients (12%, avulsion fracture of the lateral malleolus was found, and in 36 cases (17%, effusion in the talocrural joint was detected. Ultrasonography failed to visualize a pathology in 19 children (9%; in 60 patients (29%, it showed avulsion fracture of the lateral malleolus involving the attachment of the anterior talofi bular ligament (ATFL; in 34 cases (17%, complete ATFL tear was detected, and in 51 patients (25%, partial ATFL injury was found. Other injuries constituted 19%. The surgeries conducted to repair the anterior talofi bular ligament (19 confi rmed the US/X-ray diagnoses in 100% of cases. Avulsion ATFL injury, i.e. the one that involves the ligament attachment site, is usually found in younger children (median: 8 years of age. Complete ATFL tears (not involving the attachment site concern older children (median: 14 years of age. Conclusions: Since X-ray is of limited value in diagnosing ankle joint pathologies in recent sprain injuries in children, soft tissue imaging, i.e. ultrasonography, is the basic examination to assess the ligament complex. Avulsion fractures, which involve the ATFL attachment site and are usually found in younger children, are a consequence of the incomplete ossifi cation and require urgent diagnosis and orthopedic consultation.

Research has shown that social exclusion has devastating psychological, physiological, and behavioral consequences. However, little is known about possible ways to shield individuals from the detrimental effects of social exclusion. The present study, in which participants were excluded during a ball-tossing game, examined whether (reminders of) secure attachment relationships could attenuate neurophysiological pain- and stress-related responses to social exclusion. Social exclusion was associated with activation in brain areas implicated in the regulation and experience of social distress, including areas in the lateral and medial prefrontal cortex, ventral anterior cingulate cortex, and hypothalamus. However, less activation in these areas was found to the extent that participants felt more securely attached to their attachment figure. Moreover, the psychological presence (i.e., salience) of an attachment figure attenuated hypothalamus activation during episodes of social exclusion, thereby providing insight into the neural mechanisms by which attachment relationships may help in coping with social stress.

Full Text Available A new scale measuring patient-therapist attachment avoidance was developed. Attachment Avoidance in Therapy Scale is a new measure based on the Bartholomew model of adult attachment (Bartholomew & Horowitz, 1991 and the Experience in Close Relationships Scale (Brennan, Clark, & Shaver, 1998 to measure patients’ attachment avoidance towards therapists. With 112 patient-therapist dyads participating in the study, validation of a preliminary scale – measuring both attachment anxiety and attachment avoidance in therapy – took place using therapists’ evaluations of patients’ relational behavior and patients’ self-reports about their attitude toward psychotherapy. Analysis of the data revealed six underlying scales. Results showed all six scales to be reliable. Validation of scales measuring attachment anxiety failed. The importance of Attachment Avoidance in Therapy Scale and its subscales is discussed.

Attachment theory and reactive attachment disorder (RAD). To highlight current perspectives on attachment theory, RAD, and treatment implications using a case study of an 8-year-old patient with RAD. Selected multidisciplinary literature related to attachment theory and RAD. The literature provides a body of work that substantiates the importance of early attachment relationships to human development and highlights gaps in our knowledge related to treatment of children with RAD. The quality of early attachment relationships is correlated with future personality and brain development. Attachment disturbances are associated with psychopathology in childhood and adulthood. Although evidence for the effective treatment of children with attachment disorders is minimal and inconclusive, the two major perspectives, developmental psychology and neuropsychoanalysis, offer guidelines for practice.
This article uses the framework of attachment theory to describe a behavior pattern, the anxious resistant/ambivalent attachment pattern. Examples from educational practice illustrate the condition. Possible intervention approaches are suggested. (Contains references.) (Author/DB)

Full Text Available Purpose. To evaluate the use of ocular imaging to enhance management and diagnosis of war-related anterior segment ocular injuries. Methods. This study was a prospective observational case series from an ongoing IRB-approved combat ocular trauma tracking study. Subjects with anterior segment ocular injury were imaged, when possible, using anterior segment optical coherence tomography (AS-OCT, confocal microscopy (CM, and slit lamp biomicroscopy. Results. Images captured from participants with combat ocular trauma on different systems provided comprehensive and alternate views of anterior segment injury to investigators. Conclusion. In combat-related trauma of the anterior segment, adjunct image acquisition enhances slit lamp examination and enables real time In vivo observation of the cornea facilitating injury characterization, progression, and management.
Full Text Available Dislocation of the hip joint in adults is usually caused by high-energy trauma such as road traffic accidents or falls from heights. Posterior dislocation is observed in most cases. However, atraumatic anterior dislocation of the hip joint is extremely rare. We present a case of atraumatic anterior dislocation of the hip joint that was induced by an activity of daily living. The possible causes of this dislocation were anterior capsule insufficiency due to developmental dysplasia of the hip, posterior pelvic tilt following thoracolumbar kyphosis due to vertebral fracture, and acetabular anterior coverage changes by postural factor. Acetabular anterior coverage changes in the sagittal plane were measured using a tomosynthesis imaging system. This system was useful for elucidation of the dislocation mechanism in the present case.

Tooth wear is defined as the progressive loss of a tooth’s surface due to actions other than those which cause tooth decay or dental trauma. It is a pathological condition with an increasing prevalence among young people. The aim of this article is to describe an alternative treatment modality to rehabilitate the anterior guidance by a minimally invasive interdisciplinary ortho-restorative treatment. Two patients came to the dental clinic for restorative treatment in order to rehabilitate the worn anterior dentition. Clinical analysis showed tooth surface loss located at the incisal edges by attrition due to an inadequate anterior guidance. In both cases the occlusal vertical dimension was reduced. First, following Dahl’s principle, resin attachments were placed in the upper canines. These attachments allowed the extrusion of posterior teeth in order to increase the occlusal vertical dimension. Furthermore, anterior teeth were intruded in order to create space for the restorative material. In the second phase, the restorative treatment was completed. Due to the characteristics of the case, feldspathic ceramic veneers were indicated. A diagnostic wax-up was performed to assist the treatment planning and a mock-up was prepared. Then, maxillary incisors were prepared through the mock-up to ensure a minimally invasive technique. Afterwards, silicone impressions were taken. Finally, veneers were cemented with a light-cured cement. In the present case, the functional and aesthetic parameters required by the patients were achieved, thus satisfying their needs. Key words:Tooth wear, anterior guidance, feldspathic veneers, Dahl’s principle, minimally invasive. PMID:29302293
With the ubiquity of smartphones and the rising technology of 3D printing, novel devices can be developed that leverage the "computer in your pocket" and rapid prototyping technologies toward scientific, medical, engineering, and creative purposes. This paper describes such a device: a simple 3D-printed extension for Apple's iPhone that allows the sound from an off-the-shelf acoustic stethoscope to be recorded using the phone's built-in microphone. The attachment's digital 3D files can be easily shared, modified for similar phones and devices capable of recording audio, and in combination with 3D printing technology allow for fabrication of a durable device without need for an entire factory of expensive and specialized machining tools. It is hoped that by releasing this device as an open source set of printable files that can be downloaded and reproduced cheaply, others can make use of these developments where access to cost-prohibitive, specialized medical instruments are not available. Coupled with specialized smartphone software ("apps"), more sophisticated and automated diagnostics may also be possible on-site.

Competition in markets is ubiquitous: cell-phone providers, computer manufacturers, and sport gear brands all vie for customers. Though several coexisting competitors are often observed in empirical data, many current theoretical models of competition on small-world networks predict a single winner taking over the majority of the network. We introduce a new model of product adoption that focuses on word-of-mouth recommendations to provide an explanation for this coexistence of competitors. The key property of our model is that customer choices evolve simultaneously with the network of customers. When a new node joins the network, it chooses neighbors according to preferential attachment, and then chooses its type based on the number of initial neighbors of each type. This can model a new cell-phone user choosing a cell-phone provider, a new student choosing a laptop, or a new athletic team member choosing a gear provider. We provide a detailed analysis of the new model; in particular, we determine the possibl...

Attachment theory provides an interesting background for thinking about externalizing behavior (EB) in early childhood and for understanding how parenting influences the child's outcomes. The study examined how attachment and parenting could be combined to explain preschoolers' EB. Data were collected from 117 preschoolers aged from 4 to 6 clinically referred for EB and their parents from a middle-high income population. Child attachment was measured with the Attachment Q-set; parent's rememb...

In recent years, an increasing number of studies reporting on meniscal root tears have been published. While the meniscus and its ligamentous meniscal attachments have been studied before, little is known about the transitional zone between these two structures. Therefore, the aim of this study was to mechanically and morphologically characterize the transitional zone between meniscus and its meniscal attachments. Dumbbell-shaped specimens were obtained from the transitional zone between meniscus and its meniscal attachments of 6 knee joints. Samples were divided into tibial and central layers of the anterior lateral (AL), anterior medial (AM), posterior lateral (PL) and posterior medial (PM) transitional region. Testing was performed to obtain the dissipated energy during hysteresis as well as the linear modulus (Elin), the maximum strain (εmax), the maximum engineering stress (σmax,eng) and location of rupture during tensile test to failure. Two additional knee joints were used to investigate morphological differences between meniscus, transitional zone and meniscal attachments in 8µm transverse slices. The central layer of the AL, AM and PL dissipated up to 48% less energy than the tibial layer. Elin was highest in the tibial layer of the PM with 107.4±61.1MPa and lowest in the central layer of the PL with 56.0±20.5MPa. The maximum strain was higher in the central layer than in the tibial layer at the AL, AM, and PL locations. The average σmax,eng was 12.7±9.9MPa over all location and layers. 78% of the samples ruptured during tensile test to failure in the transitional zone. The morphological evaluation showed a smooth transitional zone with a transitional curve which was either linear or bell-shaped. The strength found in the transitional zone was lower than in the meniscus and the meniscal attachments, which corresponds well to clinical findings. Copyright © 2015 Elsevier Ltd.

The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed.

In 1987 Hazan and Shaver showed that patterns of romantic love reflected attachment styles. In an extension of that study with 39 men and 33 women in college (ages 18-36 years), this research shows that family relationships may also affect romantic relationships indirectly through their association with attachment styles.

The main purpose of our research was to examine attachment type and competition anxiety in high school student athletes and general high school students. We recruited 465 student athletes and 543 general students to participate in our study. The Revised Korean version of the Experiences in Close Relationships Scale (K-ECRS) and the Competitive State Anxiety Inventory-2 (CSAI-2) were given to all students. In χ2 tests, athletes showed attachment types in the following order of prevalence: fearful, dismissive, and preoccupied, compared to the fearful, preoccupied, and dismissive order observed in general students. In parametric, independent t-tests, athletes reported significantly higher cognitive anxiety scores, relative to general students. Further, athletes with insecure attachment compared to those with secure attachment reported higher cognitive anxiety scores and self-confidence scores. In both the athletes with insecure attachment and general students with insecure attachment groups, the K-ECRS anxiety subscale was significantly correlated with CSAI-2 total score. In post hoc analysis in the athletes with insecure attachment group, the K-ECRS anxiety subscale was also significantly correlated with the CSAI-2 cognitive anxiety subscale. These results suggest that anxious athletes with an insecure attachment style tend to exaggerate threats from both external and internal sources, which negatively affect their performances.

Full Text Available Research in both infants and adults demonstrated that attachment expectations are associated with the attentional processing of attachment-related information. However, this research suffered from methodological issues and has not been validated across ages. Employing a more ecologically valid paradigm to measure attentional processes by virtue of eye tracking, the current study tested the defensive exclusion hypothesis in late childhood. According to this hypothesis, insecurely attached children are assumed to defensively exclude attachment-related information. We hypothesized that securely attached children process attachment- related neutral and emotional information in a more open manner compared to insecurely attached children. Sixty-two children (59.7% girls, 8-12 years completed two different tasks, while eye movements were recorded: task one presented an array of neutral faces including mother and unfamiliar women and task two presented the same with happy and angry faces. Results indicated that more securely attached children looked longer at mother's face regardless of the emotional expression. Also, they tend to have more maintained attention to mother's neutral face. Furthermore, more attachment avoidance was related to a reduced total viewing time of mother's neutral, happy, and angry face. Attachment anxiety was not consistently related to the processing of mother's face. Findings support the theoretical assumption that securely attached children have an open manner of processing all attachment-related information.

We are interested in testing the antimicrobial activity of a porphyrin that is attached to a polymer. The porphyrin (5-(4-carboxyphenyl)-10,15,20-tris-(4-pryridyl)) was synthesized from methyl 4-formyl benzoate, 4-pyridinecarboxaldehyde, and pyrrole and attached to a copolymer of polystyrene/poly(vinyl benzyl chloride), which was synthesized by free radical polymerization. The antimicrobial activity of the polymer-attached porphyrin was then determined for gram-negative E. Coli grown to 0.80 OD. In this procedure, glass slides were coated with polymer-attached porphyrin via dip-coating, and the E. Coli bacteria were plated in Luria Broth media. The plates were subsequently exposed to light overnight before they were incubated as porphyrins act as photo-sensitizers when irradiated with light. The polymer-attached porphyrin did exhibit antimicrobial activity and parameters that affect its efficiency will be discussed.

A significant amount of research in attachment theory has been devoted to factors affecting academic achievement, but less attention has been given to the role of attachment in the relation between academic achievement and achievement motivation. The current preliminary study examined the role of perceived parental attachment in achievement motivation. Self-report data obtained from the Parental Attachment Questionnaire, Achievement Goals Questionnaire, and the Performance Failure Appraisal Inventory were collected from 50 university students with a mean age of 18.8 yr. Correlation and regression analyses indicated that parental facilitation of independence correlated significantly and negatively with fear of failure. Results yielded partial support for the hypothesis that performance-oriented goals are related to a fear of failure, whereas mastery-oriented goals are not. The results also suggest that high parental attachment in the case of high-frequency religious practitioners is related to an increased chance of acquiring a more avoidance-oriented achievement motivation.

Context: Anterior cruciate ligament (ACL) reconstruction rehabilitation has evolved over the past 20 years. This evolution has been driven by a variety of level 1 and level 2 studies. Evidence Acquisition: The MOON Group is a collection of orthopaedic surgeons who have developed a prospective longitudinal cohort of the ACL reconstruction patients. To standardize the management of these patients, we developed, in conjunction with our physical therapy committee, an evidence-based rehabilitation guideline. Study Design: Clinical review. Level of Evidence: Level 2. Results: This review was based on 2 systematic reviews of level 1 and level 2 studies. Recently, the guideline was updated by a new review. Continuous passive motion did not improve ultimate motion. Early weightbearing decreases patellofemoral pain. Postoperative rehabilitative bracing did not improve swelling, pain range of motion, or safety. Open chain quadriceps activity can begin at 6 weeks. Conclusion: High-level evidence exists to determine appropriate ACL rehabilitation guidelines. Utilizing this protocol follows the best available evidence. PMID:26131301

Objectives Infants and toddlers need secure attachments in order to develop the social competence required to successfully navigate later peer and adult relationships. Breastfeeding is a parenting factor that has been associated with child emotional development-specifically the attachment between children and their mothers. Yet, this link may simply be the result of other parenting behaviors that are associated with breastfeeding. Thus, our objective is to examine whether the link between infant attachment behaviors and breastfeeding endures when accounting for a broad array of in-depth measures of parenting. Methods We use the Early Childhood Longitudinal Study of children from 9 months to 2 years of age collected by the National Center for Education Statistics. Using Ordinary Least Squares regression, data analyses examine the association between the Toddler Attachment Sort-45 (TAS-45) measures of toddler-parent attachment (infant attachment security and temperamental dependency) and breastfeeding practices. We also examine individual items of the TAS-45 to isolate specific attachment behaviors that have the strongest associations with breastfeeding. Results We find an enduring link between children who are predominantly breastfed for six or more months and infant attachment security. However, we find no evidence that breastfeeding is linked to a child's temperamental dependency. Of the nine items used to examine infant attachment behaviors, we find that breastfed children are rated as having slightly higher scores on two measures ("warm and cuddly," "cooperative") and lower scores on one measure ("demanding/angry"). Conclusions for Practice Breastfeeding has an important link to the child's use of their caregiver as a secure base for exploration and a place of comfort when distressed (infant attachment security). Yet, breastfeeding does not appear to reduce a child's temperamental dependency or level of clinginess as measured by how demanding, fussy or

Most attachment theorists assume that parenting style is the central mechanism linking the quality of parents' attachment with their parents and adaptation in their children. Outside the attachment tradition, family risk models assume that many family factors affect children's adaptation, chief among them being couple relationship quality. The present study tests an integrated model that considers both theoretical and empirical links between attachment theory and family risk research. Seventy-three fathers and mothers whose first child was about to make the transition to elementary school were administered the Adult Attachment Interview and a new Couple Attachment Interview. The parents were also observed in separate visits during kindergarten year in interaction with each other and with their child. At the end of first grade, we obtained children's academic achievement test results and teachers' checklist observations of internalizing and externalizing behaviors. Structural equations revealed that a family risk model that includes information from working models of attachment and observations of couple interaction predicts substantial variation in children's adaptation to elementary school.

To determine the relationship of prenatal attachment and other selected perinatal contextual variables (method of delivery, maternal self-reported health, depression, infant birthweight, need for neonatal intensive care unit [NICU] admission) to postnatal attachment in mothers of twins. Two hundred fourteen women were initially recruited from a national mothers of twins support group for a study of maternal prenatal attachment. Of the 168 women who agreed to be contacted after delivery, 142 returned completed questionnaires (82.7% response rate), with 139 study-eligible women included in the analysis for this report. Correlational design with longitudinal follow-up at 1 month after expected delivery date. Self-administered, mailed questionnaires completed by women with twin gestations prenatally and postnatally 1 month after their expected delivery dates. Descriptive analysis, correlations, and regression equations were performed. The Maternal Attachment Inventory. A modest correlation was found between prenatal and postnatal attachment ( r = 0.38, P Prenatal attachment and postpartum depression explained 26.1% of the variance in postnatal attachment ( F = 5.06, P prenatal attachment and postnatal attachment. The addition of these interaction terms nominally increased the adjusted R 2 to explain 27.9% to 29.6% of the variance in postnatal attachment. Although the study findings support a modest relationship between prenatal and postnatal attachment in mothers of twins, maternal depression was also significant in explaining postnatal attachment. Postpartum depression, having a cesarean delivery, and the experience of a NICU admission for 1 or both twins further influenced the relationship between prenatal attachment and postnatal attachment. When fostering attachment in mothers of twins, nurses should assess for symptoms of depression and pay particular attention to those women who have an infant requiring a NICU admission.

Anatomic femoral tunnel placement for single-bundle anterior cruciate ligament (ACL) reconstruction is now well accepted. The ideal location for the tibial tunnel has not been studied extensively, although some biomechanical and clinical studies suggest that placement of the tibial tunnel in the anterior part of the ACL tibial attachment site may be desirable. However, the concern for intercondylar roof impingement has tempered enthusiasm for anterior tibial tunnel placement. To compare the potential for intercondylar roof impingement of ACL grafts with anteriorly positioned tibial tunnels after either transtibial (TT) or independent femoral (IF) tunnel drilling. Controlled laboratory study. Twelve fresh-frozen cadaver knees were randomized to either a TT or IF drilling technique. Tibial guide pins were drilled in the anterior third of the native ACL tibial attachment site after debridement. All efforts were made to drill the femoral tunnel anatomically in the center of the attachment site, and the surrogate ACL graft was visualized using 3-dimensional computed tomography. Reformatting was used to evaluate for roof impingement. Tunnel dimensions, knee flexion angles, and intra-articular sagittal graft angles were also measured. The Impingement Review Index (IRI) was used to evaluate for graft impingement. Two grafts (2/6, 33.3%) in the TT group impinged upon the intercondylar roof and demonstrated angular deformity (IRI type 1). No grafts in the IF group impinged, although 2 of 6 (66.7%) IF grafts touched the roof without deformation (IRI type 2). The presence or absence of impingement was not statistically significant. The mean sagittal tibial tunnel guide pin position prior to drilling was 27.6% of the sagittal diameter of the tibia (range, 22%-33.9%). However, computed tomography performed postdrilling detected substantial posterior enlargement in 2 TT specimens. A significant difference in the sagittal graft angle was noted between the 2 groups. TT grafts were

The authors present and validate the Patient Attachment Coding System (PACS), a transcript-based instrument that assesses clients' in-session attachment based on any session of psychotherapy, in multiple treatment modalities. One-hundred and sixty clients in different types of psychotherapy (cognitive-behavioural, cognitive-behavioural-enhanced, psychodynamic, relational, supportive) and from three different countries were administered the Adult Attachment Interview (AAI) prior to treatment, and one session for each client was rated with the PACS by independent coders. Results indicate strong inter-rater reliability, and high convergent validity of the PACS scales and classifications with the AAI. These results present the PACS as a practical alternative to the AAI in psychotherapy research and suggest that clinicians using the PACS can assess clients' attachment status on an ongoing basis by monitoring clients' verbal activity. These results also provide information regarding the ways in which differences in attachment status play out in therapy sessions and further the study of attachment in psychotherapy from a pre-treatment client factor to a process variable. Copyright © 2015 John Wiley & Sons, Ltd. The Patient Attachment Coding System is a valid measure of attachment that can classify clients' attachment based on any single psychotherapy transcript, in many therapeutic modalities Client differences in attachment manifest in part independently of the therapist's contributions Client adult attachment patterns are likely to affect psychotherapeutic processes.

Attachment security towards parents and peers in adolescence, and romantic attachment styles and emotion regulation strategies in young adulthood, were evaluated using an eight-year longitudinal design. Fifty-six young adults completed the Inventory of Parent and Peer Attachment (IPPA) at age 14, and then, at age 22, the Experience in Close Relationships (ECR) and the Coping Inventory for Stressful Situations (CISS), an emotion regulation questionnaire concerning coping strategies, including task-oriented versus emotion-oriented foci. Results indicated that greater insecurity to parents and peers in adolescence predicted a more anxious romantic attachment style and greater use of emotion-oriented strategies in adulthood. Concurrently, anxious adult attachment style was related to more emotion-oriented strategies, whereas an avoidant attachment style was related to less support-seeking. Analyses also identified emotion-oriented coping strategies as a partial mediator of the link between adolescent attachment insecurity to parents and adult anxious attachment, and a complete mediator of the association between adolescent attachment insecurity to peers and adult anxious attachment. These findings support the core assumption of continuity in attachment theory, where relationships to parents influence close romantic relationships in adulthood.

Assessments of anterior cingulate cortex in experimental animals and humans have led to unifying theories of its structural organization and contributions to mammalian behaviour. The anterior cingulate cortex forms a large region around the rostrum of the corpus callosum that is termed the anterior executive region. This region has numerous projections into motor systems, however, since these projections originate from different parts of anterior cingulate cortex and because functional studies have shown that it does not have a uniform contribution to brain functions, the anterior executive region is further subdivided into 'affect' and 'cognition' components. The affect division includes areas 25, 33 and rostral area 24, and has extensive connections with the amygdala and periaqueductal grey, and parts of it project to autonomic brainstem motor nuclei. In addition to regulating autonomic and endocrine functions, it is involved in conditioned emotional learning, vocalizations associated with expressing internal states, assessments of motivational content and assigning emotional valence to internal and external stimuli, and maternal-infant interactions. The cognition division includes caudal areas 24' and 32', the cingulate motor areas in the cingulate sulcus and nociceptive cortex. The cingulate motor areas project to the spinal cord and red nucleus and have premotor functions, while the nociceptive area is engaged in both response selection and cognitively demanding information processing. The cingulate epilepsy syndrome provides important support of experimental animal and human functional imaging studies for the role of anterior cingulate cortex in movement, affect and social behaviours. Excessive cingulate activity in cases with seizures confirmed in anterior cingulate cortex with subdural electrode recordings, can impair consciousness, alter affective state and expression, and influence skeletomotor and autonomic activity. Interictally, patients with anterior

Conclusions This technique is offered as a convenient and reliable method for cases with anterior TM perforation and inadequate anterior remnant. Objectives Chronic otitis media surgery is one of the most common procedures in otology. Anterior tympanic membrane (TM) perforation with inadequate anterior remnant is associated with higher rates of graft failure. It was the goal of this series to evaluate the anatomical and functional outcomes of a modified underlay myringoplasty technique-the anterior pull-through method. Materials and methods In a retrospective clinical study, 13 patients with anterior TM perforations with inadequate anterior remnants underwent tympanoplasty with anterior pull-through technique. The anterior tip of the temporalis fascia was pulled through and secured in a short incision lateral to the anterior part of the annulus. Data on graft take rate, pre-operative, and post-operative hearing status were analyzed. Results A graft success rate of 84.6% (11 out of 13) was achieved, without lateralization, blunting, atelectasia, or epithelial pearls. The air-bone gap was 21.5 ± 6.8 dB before intervention and 11.75 ± 5.7 dB after surgery (p = 0.003).

Context: Reconstruction of the anterior cruciate ligament (ACL) is one of the most common surgical procedures, with more than 200,000 ACL tears occurring annually. Although primary ACL reconstruction is a successful operation, success rates still range from 75% to 97%. Consequently, several thousand revision ACL reconstructions are performed annually and are unfortunately associated with inferior clinical outcomes when compared with primary reconstructions. Evidence Acquisition: Data were obtained from peer-reviewed literature through a search of the PubMed database (1988-2013) as well as from textbook chapters and surgical technique papers. Study Design: Clinical review. Level of Evidence: Level 4. Results: The clinical outcomes after revision ACL reconstruction are largely based on level IV case series. Much of the existing literature is heterogenous with regard to patient populations, primary and revision surgical techniques, concomitant ligamentous injuries, and additional procedures performed at the time of the revision, which limits generalizability. Nevertheless, there is a general consensus that the outcomes for revision ACL reconstruction are inferior to primary reconstruction. Conclusion: Excellent results can be achieved with regard to graft stability, return to play, and functional knee instability but are generally inferior to primary ACL reconstruction. A staged approach with autograft reconstruction is recommended in any circumstance in which a single-stage approach results in suboptimal graft selection, tunnel position, graft fixation, or biological milieu for tendon-bone healing. Strength-of-Recommendation Taxonomy (SORT): Good results may still be achieved with regard to graft stability, return to play, and functional knee instability, but results are generally inferior to primary ACL reconstruction: Level B.

Attachment security is associated with health and possibly autonomic and endocrine reactivity to stress, however the relationship between attachment style and immune function has not yet been investigated. A random sample of 61 female nurses provided a blood sample and completed the Perceived Stress Scale, the Multidimensional Scale of Perceived Social Support, the 20-item Toronto Alexithymia Scale, and the Experiences in Close Relationships questionnaire. Immune measures included immunophenotypic analysis, lymphocyte proliferative response to Phytohemagglutinin, and NK cell cytotoxicity (NKCC). Statistical analysis focused on the relationship between attachment-related anxiety or avoidance and immune measures. Multiple regression was used to control for perceived stress and support, alexithymia, health-related behaviors possibly influencing immunity, and use of anti-inflammatory drugs, tobacco or alcohol. Attachment-related anxiety was not associated with any immune parameter. Attachment-related avoidance was associated with lower NKCC. This association was independent from the number of circulating NK cells, which suggests a change in cell functionality. Perceived stress was also associated with lower NKCC. This study suggests a link between attachment security and immunity. While our findings should be interpreted with great caution and need replication, they are consistent with previous work suggesting that insecure attachment may be a risk factor for health and may relate to biological processes relevant to health.
Full Text Available The research presented in this paper aimed to explore relations between stressful life experiences and attachment in adolescence. The sample included 279 adolescents of both sexes, who were students of first two years at the University of Novi Sad. Attachment styles were assessed by RQ (Relationship Questionnaire, Bartolomew & Horowitz, 1991, and stressful experiences by Risk Scale (Grossman et al., 1990. The average score on the Risk scale indicated that participants had relatively small number of stressful events; but majority had at least two stressful experiences. The most frequent event was loss of family member (61,2% of participants and traffic accident (40,6% of participants. Participants with secure and insecure attachment styles had similar number of stressful experiences in their lives. Difference between these groups was significant only in the case stressors that origin from the characteristics of the family and intrafamilial relations, which was more frequent experience in participants with insecure attachment styles. However, the results showed that stressful experiences may have negative influence on security of attachment, i.e. on positivity of model of self. The highest and statistically significant contribution was made by separation from family and by family characteristics. The results are discussed in context of attachment theory and previous research data on effects of stressful and traumatic events on security of attachment.
Full Text Available Abstract Attachment theory predicts and subsequent empirical research has amply demonstrated that individual variations in patterns of early attachment behaviour are primarily influenced by differences in sensitive responsiveness of caregivers. However, meta-analyses have shown that parenting behaviour accounts for about one third of the variance in attachment security or disorganisation. The exclusively environmental explanation has been challenged by results demonstrating some, albeit inconclusive, evidence of the effect of infant temperament. In this paper, after reviewing briefly the well-demonstrated familial and wider environmental influences, the evidence is reviewed for genetic and gene-environment interaction effects on developing early attachment relationships. Studies investigating the interaction of genes of monoamine neurotransmission with parenting environment in the course of early relationship development suggest that children's differential susceptibility to the rearing environment depends partly on genetic differences. In addition to the overview of environmental and genetic contributions to infant attachment, and especially to disorganised attachment relevant to mental health issues, the few existing studies of gene-attachment interaction effects on development of childhood behavioural problems are also reviewed. A short account of the most important methodological problems to be overcome in molecular genetic studies of psychological and psychiatric phenotypes is also given. Finally, animal research focusing on brain-structural aspects related to early care and the new, conceptually important direction of studying environmental programming of early development through epigenetic modification of gene functioning is examined in brief.

One of teenagers' key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents' social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging. We asked n = 44 adolescents (ages 12.01-18.84 years) to evaluate positive and negative adjectives regarding either themselves or a close other during an adapted version of the well-established self-other trait-evaluation task. As measures of attachment, we obtained scores reflecting participants' positive versus negative attachment-derived self- and other-models by means of the Relationship Questionnaire. We controlled for possible confounding factors by also obtaining scores reflecting internalizing/externalizing problems, schizotypy, and borderline symptomatology. Our results revealed that participants with a more negative attachment-derived self-model showed increased brain activity during positive and negative adjective evaluation regarding the self, but decreased brain activity during negative adjective evaluation regarding a close other, in bilateral amygdala/parahippocampus, bilateral anterior temporal pole/anterior superior temporal gyrus, and left dorsolateral prefrontal cortex. These findings suggest that a low positivity of the self-concept characteristic for the attachment anxiety dimension may influence neural information processing, but in opposite directions when it comes to self- versus (close) other-representations. We discuss our results in the framework of attachment theory and regarding their implications especially for adolescent social-emotional development and social integration.

In China, research on the relation of mother-infant attachment to children's development is scarce. This study sought to investigate the relation of mother-infant attachment to attachment, cognitive and behavioural development in young children. This study used a longitudinal study design. The subjects included healthy infants (n=160) aged 12 to 18 months. Ainsworth's "Strange Situation Procedure" was used to evaluate mother-infant attachment types. The attachment Q-set (AQS) was used to evaluate the attachment between young children and their mothers. The Bayley scale of infant development-second edition (BSID-II) was used to evaluate cognitive developmental level in early childhood. Achenbach's child behaviour checklist (CBCL) for 2- to 3-year-olds was used to investigate behavioural problems. In total, 118 young children (73.8%) completed the follow-up; 89.7% of infants with secure attachment and 85.0% of infants with insecure attachment still demonstrated this type of attachment in early childhood (κ=0.738, pdevelopment index (MDI) in early childhood than did infants with secure attachment, especially the resistant type. In addition, resistant infants were reported to have greater social withdrawal, sleep problems and aggressive behaviour in early childhood. There is a high consistency in attachment development from infancy to early childhood. Secure mother-infant attachment predicts a better cognitive and behavioural outcome; whereas insecure attachment, especially the resistant attachment, may lead to a lower cognitive level and greater behavioural problems in early childhood.

Full Text Available Objective To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction.

The hyperbolic cosine function is shown to be an accurate representation of the form of the mandibular anterior teeth from the canine/first premolar contact on one side around the perimeter to the opposite side (r = 0.951). On the basis of this mathematical function, the changes in canine width, anterior segment depth, arch perimeter, and their related incisor angular alterations are forecastable. This knowledge will allow the clinician to predict the effects on various aspects of the anterior segment arch form as one or more of these variables are altered without resorting to trial and error or performing a wax-up. For example, the clinician can predict the change in the anterior segment arch depth and incisor angulation that would occur with alterations in canine width.

Full Text Available Background: Although anterior shoulder dislocation is the most prevalent type of body dislocation, irreducible anterior shoulder dislocation is seldom reported in the literature, which is usually due to physical obstacles. Objectives: This study presents our findings regarding the causes of irreducibility of anterior shoulder dislocation associated with displaced fracture of the greater tuberosity. Patients and Methods: CT scans, open reduction of the joint, and internal fixation of the tuberosity was performed in seven patients with irreducible anterior shoulder dislocation associated with displaced fracture of the greater tuberosity. Results: As confirmed by intraoperative findings, the CT scans showed the cause of irreducible shoulder dislocation in six cases was the interposition of the long head of biceps (LHB in the anterior of the head that was displaced from the fracture line between the greater and lesser tuberosities. In another case, the greater and lesser tuberosities were attached to each other and were separated from the head. This fractured part was trapped. Conclusions: We suggest that performing CT scans in all cases of anterior shoulder dislocations with displaced fracture of the greater tuberosity can help surgeons to diagnose the accompanying fractures and possible complications, such as irreducibility. If the fracture line passes through the bicipital groove or in the case of a shield fracture, possible irreducibility should be borne in mind.

Using a bull's-eye hierarchical mapping technique (HMT), the present study examined placement of parents in adults' attachment networks over time. We hypothesized that attachment style would predict distance at which network members (mother, father, and romantic partner) would be placed from the core-self over time. Participants completed the HMT on two occasions, 12 months apart. Concurrently and over time, fathers were placed further from the core-self than mothers. Attachment style explained unique variance, beyond that accounted for by individual and relationship characteristics. Specifically, network members with whom participants reported greater attachment insecurity were placed further from the core-self concurrently. Mothers with whom participants reported greater attachment insecurity were placed further from the core-self over time. Unsatisfactory attachment relationships with father and partner and those marked by higher attachment insecurity were more likely to be excluded from attachment networks over time. Findings suggest that attachment style, relationship quality, romantic relationship status, and parents' marital status determine the placement of parents in adults' attachment networks.

[corrected] The Szondi-test is widely applied in clinical diagnostics in Hungary too, and the evidence resulting from the theory is that we can get information about attachment during its interpreting. Its validity is proven by empirical research and clinical experiences. By analyzing the modern attachment theory more thoroughly, it becomes clear in what ways the Szondi-test constellations regarding attachment are different from the classificationbased on questionnaires, allowing the discrete measurement of the attachment style. With the Szondi-test the classification to attachment style is more insecure, but if it is completed with exploration, it is more informative in vector C (vector of relation, attachment information), while short questionnaires make the classification to attachment style possible. In our empirical analysis we represent the integration of the above mentioned clinical and theoretical experiences. In the present analysis we compare the vector C and S constellation of the two-profile Szondi-test of 80 persons with the dimensions of ECR-R questionnaire and with Collins and Read's questionnaire classification regarding attachment style. The statistical results refer to the fact that there is a legitimacy to compare questionnaire processes allowing the discrete classification of attachment and the Szondi-test's information content regarding attachment. With applying the methods together, we get a unique, complementary section of the information relating to attachment. Comparing the two methods (projective and questionnaire) establishes the need of theoretical integration as well. We also make an attempt to explain Fraley's evolutionary non-adaptivity of avoidant attachment, in the case of whose presence adaptivity of early attachment, counterbalancing the exploration and security need, and providing closeness--farness loses its balance.

The pressure gradient between anterior and posterior chamber in acute angle closure (AAC) and primary angle closure suspects is balanced by a sufficient laser peripheral iridotomy (LPI). The anterior chamber changes induced by LPI in patients with unilateral AAC were examined and compared to healthy eyes to define threshold values, which may help to discriminate between healthy and diseased eyes. Using Scheimpflug photography, anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), and central corneal thickness (CCT) were measured before and after LPI in both eyes of unilateral AAC cases. These measurements were compared to a group of healthy control eyes to determine threshold values for ACD, ACV, and ACA. The ACD, ACV, and ACA increased significantly in the 25 AAC eyes after LPI. The ACD, ACV, ACA, and CCT values in the AAC eyes obtained before LPI were compared to a control group of 59 healthy eyes with wide open chamber angles. The cutoff values revealed by receiver operating characteristic analysis were 2.1 mm for ACD, 90.5 mm2 for ACV, and 27.25° for ACA. Our results confirm the significant changes of the anterior segments architecture induced by LPI in AAC eyes. The found threshold values for ACD, ACV, and ACA may help in daily clinical routine to discriminate between healthy eyes and those in need for a prophylactic LPI.

There are least two different but interrelated motivational systems in human beings both of which begin in infancy: the attachment system and the separate, but interacting, psychodynamic system. Each of these systems is the basis of transference. A major focus of the paper is the affect-regulating feature of the attachment system. Infants' emotional states can be well-regulated or dysregulated as they emerge in interactions with their primary caregiver. Aberrant interactions of dysregulation typically lead to the development of insecure or disorganized attachments. Rudimentary transference fantasies initially emerge as the child makes sense or meaning about such maladaptive interactions. Our complex minds comprise multi-determined, personally organized fantasies which include those derived from both the attachment system and the psychodynamic one. I present a clinical description of how these two transference fantasies intersect in the mental life of a patient. A clinical case is offered whose focus is on enactments, transferences, and countertransference.
To describe the ophthoselfie, a method by which everyone can take detailed self-images of the cornea and anterior segment with a smartphone. A 90-diopter non-contact double aspheric lens was attached to posterior camera of the smartphone by clear tape. Images of one eye on the screen of the smartphone could be seen with the other eye in the mirror and images were taken. Accurate and detailed images of the cornea and anterior segment of the eye could be taken. The ophthoselfie allows everyone to take their own detailed anterior segment images by smartphone. To create a clear and detailed self-image of the cornea and anterior segment on the screen of a smartphone may lead to the development of new applications and facilitate patients' early recognition of certain conditions like keratoconus, refractive errors, corneal rejection, and uveitis. This method may also be useful in some urgent situations by allowing patients to take self-images of the eye and share them with a physician.

Emotion regulation and quality of attachment are closely linked. It has been proposed here that one influence on individual differences in emotion regulation may be a child's attachment history. Individuals characterized by the flexible ability to accept and integrate both positive and negative emotions are generally securely attached; on the other hand, individuals characterized by either limited or heightened negative affect are more likely to be insecurely attached. While acknowledging the role of infant temperament, I have focused on the role of social factors in examining the link between emotion regulation and attachment. The approach to emotion regulation taken here--that emotion regulation is adaptive in helping a child attain her goals--is esentially a functionalist approach (Bretherton et al., 1986; Campos et al., 1983), consistent with earlier views of emotions as important regulators of interpersonal relationships (Charlesworth, 1982; Izard, 1977). It has been proposed that patterns of emotion regulation serve an important function for the infant: the function of maintaining the relationship with the attachment figure. Emotion regulation has been described as serving this function in two ways. First, the function of maintaining the relationship is thought to be served when infant emotion regulation contributes to the infant's more generalized regulation of the attachment system in response to experiences with the caregiver. Infants who have experienced rejection (insecure/avoidant infants) are thought to minimize negative affect in order to avoid the risk of further rejection. Infants whose mothers have been relatively unavailable or inconsistently available (insecure/ambivalent infants) are thought to maximize negative affect in order to increase the likelihood of gaining the attention of a frequently unavailable caregiver. Both these patterns of emotion regulation help ensure that the child will remain close to the parent and thereby be protected

Thoughtful observations and research can help society understand violence and enable us to find ways of preventing future instances of horrible events. Healthy, developmentally appropriate, and successful attachments need to be formed in order for children to grow up to be healthy adults.

Agrobacterium tumefaciens binds to the surfaces of inanimate objects, plants, and fungi. These bacteria are excellent colonizers of root surfaces. In addition, they also bind to soil particles and to the surface of artificial or man-made substances, such as polyesters and plastics. The mechanisms of attachment to these different surfaces have not been completely elucidated. At least two types of binding have been described unipolarpolysaccharide-dependent polar attachment and unipolar polysac...

Tobacco has been recognized as the number one cause of preventable death in America and results in almost 5.2 million years of potential life lost each year. The use of tobacco products is highly correlated with pulmonary disease, cardiovascular disease, and other forms of chronic illness in America. New tobacco products are trending in the tobacco market such as the water pipe/hookah and e-cigarettes. With e-cigarettes and other newer forms of tobacco on the rise, it is important to look at the underlying factors for using all kinds of tobacco products as a means of prevention. Certain adult attachment styles (secure, preoccupied, dismissing-avoidant, and fearful-avoidant) in emotionally meaningful relationships could be indicators for physical illness, mental illness, and even addiction. This study investigated whether or not there is a relationship between tobacco use and attachment style. Based on a university-wide survey that was sent out at a university in Appalachia with 522 participants, demographic data revealed 68.5% (n = 358) did not currently use tobacco products. Of those who did currently use tobacco products 54.5% (n = 90) were male, 84.8% (n = 140) were undergraduate students, and 66.7% (n = 110) were between the ages of 18-25. For individuals who used tobacco 23.5% (n = 38) were in the secure attachment group, 27.8% (n = 45) were in the dismissing-avoidant attachment group, 30.2% (n = 49) were in the fearful-avoidant attachment group, and 18.5% (n = 30) were in the preoccupied attachment group. Chi Square analysis demonstrated that attachment style was significantly (p tobacco users and non-users revealing that there is a possibility for prevention of smoking initiation through the development of a secure attachment style.

The purpose of this biomechanical study was to investigate the potential effect of a nonanatomic repair of the meniscal horn attachment on the resultant circumferential tension in a large animal model and to show that the circumferential tension of the meniscus affects the local stress of the cartilage. All investigations were done in the medial compartment of porcine knees. First, the anterior horn attachment of the meniscus was mechanically separated from the surrounding tibial bone and fitted with a force transducer (n = 8). The femorotibial joint was loaded in compression at different flexion angles, and the resultant tension at the horn attachment was recorded. The measurements were done with the horn attachment at its anatomic position and repeated with the horn attachment being displaced medially or laterally by 3 mm. In the second part the local deformation of the cartilage under a femorotibial compressive load was measured at different levels of meniscal hoop tension (n = 5). A nonanatomic position of the horn attachment had a significant effect on the resultant tension (P horn attachment 3 mm medially decreased the tension at the horn attachment by 49% to 73%, depending on flexion angle and femorotibial load. The opposite placement resulted in a relative increase in the tension by 28% to 68%. Lower levels of meniscal hoop tension caused increased deformation of the cartilage (P horn attachment strongly affects conversion of femorotibial loads into circumferential tension. There is a narrow window for a functionally sufficient repair of meniscal root tears. Although clinical inferences are limited because the specimens used were from a different species, there seems to be only a narrow window for a mechanically sufficient repair of root tears.

This article presents attachment theory-based intervention strategies as a means of addressing the core parent-child interaction deficits that characterize homes in which children are exposed to maltreatment. The article outlines the socioemotional and cognitive outcomes of maltreatment and proposes that although many prevention programs target different parental and family characteristics, few address the core relationship issues that are at stake. Recent research on attachment-based intervention strategies, aimed at improving the sensitivity and responsiveness of the parenting behaviors that children are exposed to, are presented as providing a means of addressing this domain. Attachment theory and research are briefly summarized, and the relational and interactional patterns observed in maltreating families, and their link to infant and child developmental outcome, are described. Research on attachment-based intervention is addressed, with a focus on studies conducted in the context of maltreating or high-risk families. This work is synthesized to present the basic components viewed as critical to effective attachment intervention with maltreating families. Finally, the authors end with recommendations aimed at the effective implementation of attachment-based intervention. (c) 2009 APA, all rights reserved

Hikikomori (acute social withdrawal) is a social issue in Japan that affects both the society and the lives of the individual sufferers. This study aims to connect attachment theory and hikikomori by using a culturally sensitive psychosocial developmental model that outlines the various stages of attachment throughout the developmental years. Twenty-four hikikomori sufferers and 60 comparison group participants were given questionnaires assessing parent and peer relationships, temperament and school experiences. We found the hikikomori participants had a higher incidence of ambivalent attachment, reported more parental and peer rejection and bullying, and expressed greater temperamental shyness. Path analysis supported our developmental model. We found that shy temperament and parental rejection predicted ambivalent attachment, which when coupled with peer rejection predicted hikikomori. Our model implies that treatment and prevention may require attention to attachment insecurities in early childhood, peer rejection in middle childhood and/or early adolescence. We believe it is helpful in understanding hikikomori to first understand how the attachment system balances security with exploration and the anxiety associated with novelty and challenge. Finally, we examine implications of the model for intervention, treatment and future research.

This study examined whether an individual's attachment style and/or a couple's combination of attachment styles predicted violence within the marriage and explored whether other variables moderated the risk of violence. Measures of attachment style were administered to 41 discordant couples who presented to four different clinics. The couples' presenting complaints were not violence, and those who did report violence on questioning did not manifest severe violence, i.e., requiring shelters or legal intervention. Self-report measures of violence and marital satisfaction, including problem-solving communication, were also given. Using analysis of covariance and logistic regression, the relative contributions to strength of predicting being a victim of conjugal violence were calculated. An anxious attachment style was a significant predictor of females being victims of violence and of men not being victims. A dismissive style in men was predictive of men being victims when entered into the model with problem solving communication. The combination of anxiously attached females and dismissive males was a potent predictor of violence, and longer duration of marriage and poor problem-solving communication added power to the prediction. Marital interaction, which is influenced by couples' attachment styles and problem-solving communication, is a significant factor in marital partners experiencing physical violence. For couples with milder levels of violence, a more nuanced approach (compared with the legally based approach used for severe violence) seems indicated.

The main aim of this study was to investigate the associations between personality features and attachment patterns in transsexual adults. We explored mental representations of attachment, assessed personality traits, and possible personality disorders. Forty-four individuals diagnosed with gender identity disorder (now gender dysphoria), 28 male-to-female and 16 female-to-male, were evaluated using the Shedler-Westen assessment procedure-200 (SWAP-200) to assess personality traits and disorders; the adult attachment interview was used to evaluate their attachment state-of-mind. With respect to attachment, our sample differed both from normative samples because of the high percentage of disorganized states of mind (50% of the sample), and from clinical samples for the conspicuous percentage of secure states of mind (37%). Furthermore, we found that only 16% of our sample presented a personality disorder, while 50% showed a high level of functioning according to the SWAP-200 scales. In order to find latent subgroups that shared personality characteristics, we performed a Q-factor analysis. Three personality clusters then emerged: Healthy Functioning (54% of the sample); Depressive/Introverted (32%) and Histrionic/Extroverted (14%). These data indicate that in terms of personality and attachment, GD individuals are a heterogeneous sample and show articulate and diverse types with regard to these constructs.

This study examined the hypothesis that solid surfaces may stimulate attached bacteria to produce exopolymers. Addition of sand to shake-flask cultures seemed to induce exopolymer synthesis by a number of subsurface isolates, as revealed by optical microscopy. Several additional lines of evidence indicated that exopolymer production by attached cells (in continuous-flow sand-packed columns) was greater than by their free-living counterparts. Total carbohydrates and extracellular polysaccharides, both normalized to cell protein, were greater (2.5- and 5-fold, respectively) for attached cells than for free-living cells. Also, adsorption of a polyanion-binding dye to the exopolymer fraction was sixfold greater for attached cells than for unattached cells. When surface-grown cells were resuspended in fresh medium, exopolymer production decreased to the level characteristic of unattached cells, which ruled out the possibility that attached cells comprised a subpopulation of sticky mucoid variants. The mechanism by which attachment stimulated exopolymer synthesis did not involve changes of the specific growth rate, growth stage, or limiting nutrient.
Full Text Available The present study aims to determine the attachment of adolescents to their parents according to geographical regions in Turkey and gender. The research group consisted of 6061 adolescents. With an age average of 15.53 years. The Inventory of Attachment to Parents and Friends- Brief Form (EABE was used as data acquisition tool. The results of the study indicated significant difference between the scores of students regarding the inventory of attachment to parents according to regions. Evaluating the findings regarding attachment to father and mother together, the findings were similar, and the attachment levels of adolescents in Middle Anatolia, Eastern Anatolia and Black Sea Region were found to be higher than the ones in other regions. This result may be related with socioeconomic, geographical and cultural structures of the regions. Examining the finding according to gender variable, the scores of male students are significantly lower than the scores of female students. As a result according to the data gained from a wide sample group; the main factors for the attachment of adolescents to their parents in Turkey are the geographical regions in Turkey and the gender.

An anatomic study of the extraforaminal attachments of the lumbar spinal nerves was performed using human lumbar spinal columns. To identify and describe the existence of ligamentous structures at each lumbar level that attach lumbar spinal nerves to structures at the level of the extraforaminal region. During the last 120 years, several mechanisms to protect the spinal nerve against traction have been described. All these structures involved are located in the spinal canal, proximal to the intervertebral foramen. Five embalmed human lumbar spines (T12-S1) were used. Bilaterally, the extraforaminal region was dissected to describe and measure anatomic structures and their relationships. Histology was performed with staining on the sites of attachment and along the ligament. The levels T12-L2 show bilaterally 2 ligaments, a superior extraforaminal ligament and an inferior extraforaminal ligament. The superior extraforaminal ligament emerges from the joint capsule of the facet joints and inserts in both, the intervertebral disc and the ventral crista of the intervertebral foramen, passing the spinal nerve laterally. In one specimen on level L2-L3, the superior extraforaminal ligament is not attached to the spinal nerve. The inferior extraforaminal ligament emerges from the intervertebral disc, passing the nerve medially and attaching the spinal nerve. At the levels L2-L5, the inferior extraforaminal ligaments are only attached to the intervertebral disc, not to the joint capsule. Histologically, the ligaments consisted of mainly collagenous structures. Ligamentous connections exist between lumbar extraforaminal spinal nerves and nearby structures.

Sociologists and feminist scholars have, over many decades, characterised attachment as a social construction that functions to support political and gender conservatism. We accept that attachment theory has seen use to these ends and consider recent deployments of attachment theory as justification for a minimal State within conservative political discourse in the UK since 2009. However, we contest that attachment is reducible to its discursive construction. We consider Judith Butler’s depiction of the infant attached to an abusive caregiver as a foundation and parallel to the position of the adult citizen subjected to punitive cultural norms and political institutions. We develop and qualify Butler’s account, drawing on the insights offered by the work of Lauren Berlant. We also return to Foucault’s Psychiatric Power lectures, in which familial relations are situated as an island of sovereign power within the sea of modern disciplinary institutions. These reflections help advance analysis of three important issues: the social and political implications of attachment research; the relationship between disciplinary and sovereign power in the affective dynamic of subjection; and the political and ethical status of professional activity within the psy disciplines.

A beginning step in the prevention of psychopathology in children is the identification of conditions and events associated with a disproportionately high incidence of behavior problems. Rutter, Cox, Tupling, Berger and Yule (1975a, British Journal of Psychiatry, 126, 493-509) have reported a dramatic increase in the probability of children's adjustment difficulties as a function of multiple family stressors. However, this association has never been tested with infants. Among instruments of infant behavior, attachment classification has been found to be a significant predictor of later adjustment problems, particularly among low-income samples. The present investigation examines the relation between six significant familial stressors and infant attachment security in a sample of 100 low-income parent-infant dyads. Family stressors included parental criminality, maternal depressive symptomatology, maternal personality risk, overcrowding in the home, and the quality of the relationship with a significant other. Cumulative family adversity was found to differentiate secure from insecure infants, but only among families with three or four stressors present. There also was moderate support for one hypothesis derived from attachment theory, namely that stressors more closely associated with maternal functioning are more common among families with insecurely attached infants. Conceptual links between stressors and attachment are discussed, including pathways by which chronic stressors may interfere with the formation and maintenance of secure mother-infant attachment relations.
Full Text Available Emotional and cognitive development of personality have mostly been explored independently in the history of psychology. However, in the last decades, there have been more and more frequent arguments in favour of the idea that the emotional relationship between the mother and the child in early childhood, through forming a secure or insecure attachment style, is to a certain extent linked to the cognitive development. For example, securely attached children, compared to the insecurely attached, have more frequent and longer episodes of symbolic play and are more advanced in the domain of language in early childhood. Securely attached children are also more efficient and persistent in solving problems. Before starting school, securely attached children understand better the feelings and beliefs of others, as well as the fact that these determine people’s behaviour, thus having an opportunity to understand and predict this behaviour better. In this paper, we will attempt to point out some of the mechanisms that are assumed to be mediators between the emotional and cognitive development. Namely, since it enables a more independent exploration of the surroundings, more quality social relations among children, higher self-esteem, better focus and more developed communicative skills, secure attachment might potentially be linked to the cognitive development.

The proximal attachment of hamstring muscles has a very high incidence of injuries due to a wide number of factors and its morphology may be one of the underlying factors as scientific literature points out. The connective tissue component of the attachment of hamstring muscles is not well known. For this reason the aim of this study is to describe the anatomy and histology surrounding the proximal attachment of the hamstring muscles (PAHM) and its direct anatomic relations. Forty-eight cryopreserved lower limbs have sequentially been studied by means of dissection, anatomical sections and histology. All specimens studied presented an annular connective tissue structure that resembles a retinaculum, which covers and adapts to the attachment of hamstring muscles on the ischial tuberosity. The results show how this retinaculum is continuous with the long head of biceps femoris muscle, however there is a layer of loose connective tissue between the retinaculum and the semitendinosus muscle. Furthermore, this structure receives expansions of the anterior epimysium of the gluteus maximus muscle (GIM). Copyright © 2014 Elsevier Ltd. All rights reserved.

Although many studies indicate that people in low quality relationships are less healthy, precisely how relationships influence health remains unclear. We focus on one physiological pathway that may provide clues to understanding the link between relationships and health: the hypothalamic-pituitary-adrenal (HPA) axis. Evidence indicates that attachment processes in adult romantic relationships are associated with HPA responses to stress (assessed via cortisol levels). Specifically, attachment insecurity predicts different cortisol patterns than does attachment security, especially when the stressor potentially threatens the relationship. Thus, attachment may get under the skin through biological responses to attachment-relevant stressors, but further work is needed to pinpoint the complete physiological and behavioral pathways through which attachment may influence health and disease outcomes.

Attachment theory predicts cross-contextual stability of attachment representations, but research findings are rather mixed. Recently, it has been suggested that these mixed findings reflect the existence of both state and trait attachment components. The development of the State Adult Attachment Measure (SAAM) has enabled an investigation of this hypothesis. The current study aimed to evaluate the extent to which the SAAM is a useful instrument for studying such state attachment hypotheses. ...

This study examined the attachment patterns of late-adopted children (aged 4-7) and their adoptive mothers during the first 7- to 8-month period after adoption and aimed to evaluate the effect of adoptive mothers' attachment security on the revision of the attachment patterns of their late-adopted children. We assessed attachment patterns in 20 adoptive dyads and 12 genetically related dyads at two different times: T1 (time 1) within 2 months of adoption and T2 (time 2) 6 months after T1. The children's behavioural attachment patterns were assessed using the Separation-Reunion Procedure and the children's representational (verbal) attachment patterns using the Manchester Child Attachment Story Task. The attachment models of the adoptive mothers were classified using the Adult Attachment Interview. We found that there was a significant enhancement of the late-adopted children's attachment security across the time period considered (P= 0.008). Moreover, all the late-adopted children who showed a change from insecurity to security had adoptive mothers with secure attachment models (P= 0.044). However, the matching between maternal attachment models and late-adopted children's attachment patterns (behaviours and representations) was not significant. Our data suggest that revision of the attachment patterns in the late-adopted children is possible but gradual, and that the adoptive mothers' attachment security makes it more likely to occur. © 2010 Blackwell Publishing Ltd.

Retention of a mandibular denture can be achieved by an implant-retained or natural tooth-retained bar and stud attachment in the anterior segment of the mandible. The same design principles holds true for both implant-retained and tooth-retained methods of anchoring the bar and stud attachment. A simple and cost effective treatment for more complex implant overdenture is the concept of conventional tooth-retained overdentures. When few firm teeth still remain in a compromised dentition, preservation of these teeth for overdentures can improve retention and stability. The authors present a clinical report of a patient treated with a mandibular tooth-borne overdenture with bar and O-ring attachment. A splinted bar supported the prosthesis and an O-ring retained the denture.
This study was conducted to examine intergenerational transmission of attachment styles between late-adolescent children and their mothers. The purpose of the study was to reveal whether the two attachment dimensions, "Anxiety (about relationship)" and "Avoidance (of intimacy)" were related between children and their mothers, and whether these relations were mediated by the both children's and mothers' perceptions of parenting. Participants were 209 pairs of late-adolescent children and their mothers. Results revealed that the attachment dimensions of "Anxiety" and "Avoidance" in children significantly correlated to the same dimensions in their mothers. Based on attachment theory, it was hypothesized that intergenerational transmission of attachment styles was caused by the influence of the following factors: "(a) mothers' attachment styles, (b) mothers' perceptions of parenting, (c) children's perceptions of their mothers' parenting, and (d) children's attachment styles", and possible causal models of the influence processes among those variables were developed and tested in the data analyses. The results showed the validity of these processes for the intergenerational transmission of attachment styles. These results are discussed in terms of the relationships between children and mothers and late-adolescent/adult attachment styles.

The aim of this study was to determine whether or not the Parental Bonding Instrument (PBI) can provide information about parent-child attachment that is comparable to information obtained from the Adult Attachment Interview (AAI), a more complex measure of attachment. One hundred and thirty emotionally and/or behaviourally disturbed adolescents (73 male, 57 female; ages 13-19 years, x = 15.3 +/- 1.47 years) participating in a study of attachment and suicidality completed the PBI and the AAI. Data from these measures were compared within participants. Maternal care and overprotection on the PBI differed significantly by AAI attachment classification (F3,122 = 2.79, p = 0.012), with autonomous participants showing the most optimal and unresolved participants the least optimal PBI results. Maternal love and maternal involvement/role reversal on the AAI were significant predictors of maternal care and maternal overprotection, respectively, on the PBI (R2 = 0.15; R2 = 0.16). These predictions improved when AAI scales measuring idealisation and involving anger towards the mother were included in the regression analyses (R2 = 0.35; R2 = 0.20). Autonomous participants on AAI showed the highest scale correlations across instruments. Attachment information obtained from the PBI and the AAI is comparable in participants with optimal attachment histories, but not in participants showing idealisation or anger towards their mothers. Caution is, therefore, advisable when using the PBI to obtain attachment information in clinical samples where suboptimal attachment histories are likely.

Full Text Available Attachment to pets has an important role in children’s social, emotional, and cognitive development, mental health, well-being, and quality of life. This study examined associations between childhood attachment to pets and caring and friendship behaviour, compassion, and attitudes towards animals. This study also examined socio-demographic differences, particularly pet ownership and pet type. A self-report survey of over one thousand 7 to 12 year-olds in Scotland, UK, revealed that the majority of children are strongly attached to their pets, but attachment scores differ depending on pet type and child gender. Analysis revealed that attachment to pets is facilitated by compassion and caring and pet-directed friendship behaviours and that attachment to pets significantly predicts positive attitudes towards animals. The findings have implications for the promotion of prosocial and humane behaviour. Encouraging children to participate in pet care behaviour may promote attachment between children and their pet, which in turn may have a range of positive outcomes for both children (such as reduced aggression, better well-being, and quality of life and pets (such as humane treatment. This study enhances our understanding of childhood pet attachment and has implications for humane education and promoting secure emotional attachments in childhood.

Given its young, predominately male demographics and intense physical demands, the US military remains an ideal cohort for the study of anterior shoulder instability. A literature search of PubMed, MEDLINE, and the Cochrane Database was performed to identify all peer-reviewed publications from 1950 to 2016 from US military orthopaedic surgeons focusing on the management of anterior shoulder instability. Clinical review. Level 4. The incidence of anterior shoulder instability events in the military occurs at an order of magnitude greater than in civilian populations, with rates as high as 3% per year among high-risk groups. With more than 90% risk of a Bankart lesion and high risk for instability recurrence, the military has advocated for early intervention of first-time shoulder instability while documenting up to 76% relative risk reduction versus nonoperative treatment. Preoperative evaluation with advanced radiographic imaging should be used to evaluate for attritional bone loss or "off-track" engaging defects to guide comprehensive surgical management. With complex recurrent shoulder instability and/or cases of clinically significant osseous lesions, potential options such as remplissage, anterior open capsular procedures, or bone augmentation procedures may be preferentially considered. Careful risk stratification, clinical evaluation, and selective surgical management for at-risk military patients with anterior shoulder instability can optimize the recurrence risk and functional outcome in this population.

We have report two cases of aphasia that had infarcts in the distribution of the left or right anterior cerebral artery, as confirmed by computed tomography. Case 1 is a right-handed, 65-year-old man in whom computerized tomographic scanning revealed an infarction of the territory of the left anterior cerebral artery after the clipping of the anterior communicating artery aneurysm. The standard language test of aphasia (SLTA) revealed non-fluent aphasia with dysarthria, good comprehension, almost normal repetition with good articulation, and a defectiveness in writing. This syndrome was considered an instance of transcortical motor aphasia. Although three years had passed from the onset, his aphasia did not show any improvement. Case 2 is a 37-year-old man who is right-handed but who can use his left hand as well. He was admitted because of subarachnoid hemorrhage from an anterior communicating aneurysm. Because of postoperative spasm, an infarction in the distribution of the right anterior cerebral artery developed. He was totally unable to express himself vocally, but he could use written language quite well to express his ideas and had a good comprehension of spoken language. This clinical picture was considered that of an aphemia. After several weeks, his vocalization returned, but the initial output was still hypophonic.

Attachment theory is highly influential in child and adult mental health research and practice. Research and practice have started now to explore the potential value of an attachment perspective for understanding and alleviating the challenges that persons with intellectual disabilities face in mental health and social participation. Research on attachment and intellectual disabilities is reviewed on its importance for knowledge, assessment and intervention. Progress was found in understanding and distinguishing attachment behaviours, attachment relationships, attachment representations, attachment styles and attachment disorders and their respective implications for assessment and intervention. Of the various attachment-related concepts, insights into attachment behaviours and relationships showed the most promise for practical applications in the field of intellectual disabilities. Findings on representations, styles and disorders were inconclusive or preliminary. Attachment-informed research and practice can be part of emerging developmental understanding of functioning with intellectual disabilities. © 2012 Blackwell Publishing Ltd.

Restoration of anterior guidance is a major challenge to the clinician in planning of all restorative treatments. An accurate anterior guidance is important for proper function, aesthetics, comfort and phonetics. This article describes anterior rehabilitation of a patient who met with a road traffic accident and lost his anterior teeth. Anterior guidance developed in the provisional restorations was accurately recorded in the customised incisal guide table and permanent restorations were fabricated accordingly.

Vibrio cholerae is a gram-negative bacterium that causes the human disease cholera. It is found natively in brackish costal waters in temperate climates, where it attaches to the surfaces of a variety of different aquatic life. V. cholerae has a single polar flagellum making it highly motile, as well as a number of different pili types, enabling it to attach to both biotic and abiotic surfaces. Using in-house built tracking software we track all surface-attaching bacteria from high-speed movies to examine the early-time attachment profile of v. cholerae onto a smooth glass surface. Similar to previous work, we observe right-handed circular swimming trajectories near surfaces; however, in addition we see a host of distinct motility mechanisms that enable rapid exploration of the surface before forming a more permanent attachment. Using isogenic mutants we show that the motility mechanisms observed are due to a complex combination of hydrodynamics and pili-surface interactions. Lauga, E., DiLuzio, W. R., Whitesides, G.

Data from 2 separate samples using the Strange Situation paradigm were combined to assess the quality of attachment relationships in adoptive and nonadoptive mother-infant pairs. Infants were between 13 and 18 months at the time of observation. Results indicated no differences in mother-infant attachment between nonadopted and intraracial adopted subjects or between intraracial and interracial adopted subjects. Interracial adoptive mother-infant pairs did show a higher incidence of insecure attachment in comparison to nonadoptive pairs. Mothers of interracial adopted infants also were less comfortable having others care for their babies and perceived less emotional support from extended family and friends for their decision to adopt a child prior to the actual adoption than did other mothers. No relation was found, however, between quality of mother-infant attachment and either perceived social support, infant developmental quotient, infant temperament, number of foster homes experienced by the infant, or infant's age at the time of adoption placement. It was suggested that the higher incidence of psychological problems found among adoptees in middle childhood and adolescence cannot be explained in terms of insecure attachment relationships during the infancy years.

Anterior sacral meningocele is an extremely rare condition and there has been only one previous report of a prenatal diagnosis. We report the case of a 36-year-old primigravida who was referred following detection of a huge fetal pelvic cyst on routine ultrasound examination at 19 + 4 weeks' gestation. Neither fetal ultrasound nor magnetic resonance imaging (MRI) at 20 + 5 weeks' gestation could detect communication between the cyst and the spinal cord. Because extension of the pear-shaped cyst through the pelvic diaphragm down to the perineum was reminiscent of dilated vagina and uterine cervix, a tentative diagnosis of hydrometrocolpos secondary to imperforate hymen was considered. On follow-up MRI at 33 + 5 weeks' gestation, a narrow stalk connecting the pelvic cyst and the spinal canal through the anterior sacral foramen was clearly delineated, allowing us to reach the prenatal diagnosis of anterior sacral meningocele.

Anterior chamber collapse syndrome has been recognised in various species and is associated with early-life ocular disease or trauma. It is important to differentiate this acquired condition from a congenital malformation. An adult female koala (Phascolarctos cinereus) was referred for assessment of buphthalmos and severe keratitis of the right eye. The degree of keratitis obstructed examination of intraocular structures. Enucleation of the affected eye was performed and the histopathological diagnosis was anterior chamber collapse syndrome and secondary glaucoma. This case contributes to the limited information available in the literature on anterior chamber collapse syndrome, a disease unique in having secondary glaucoma with minimal or no inflammation. The case also expands the literature available on ocular disease in koalas. More specifically, this is the only reported case of glaucoma, of any aetiology, in the koala. © 2014 Australian Veterinary Association.

While attachment research has demonstrated that parents' internal working models of attachment relationships tend to be transmitted to their children, affecting children's developmental trajectories, this study specifically examines associations between adult attachment status and observable parent, child, and dyadic behaviors among children with autism and associated neurodevelopmental disorders of relating and communicating. The Adult Attachment Interview (AAI) was employed to derive parental working models of attachment relationships. The Functional Emotional Assessment Scale (FEAS) was used to determine the quality of relational and functional behaviors in parents and their children. The sample included parents and their 4- to 16-year-old children with autism and associated neurodevelopmental disorders. Hypothesized relationships between AAI classifications and FEAS scores were supported. Significant correlations were found between AAI classification and FEAS scores, indicating that children with autism spectrum disorders whose parents demonstrated secure attachment representations were better able to initiate and respond in two-way pre-symbolic gestural communication; organize two-way social problem-solving communication; and engage in imaginative thinking, symbolic play, and verbal communication. These findings lend support to the relevance of the parent's state of mind pertaining to attachment status to child and parent relational behavior in cases wherein the child has been diagnosed with autism or an associated neurodevelopmental disorder of relating and communicating. A model emerges from these findings of conceptualizing relationships between parental internal models of attachment relationships and parent-child relational and functional levels that may aid in differentiating interventions.

Attention-deficit/hyperactivity disorder (ADHD) is defined on the basis of developmentally inappropriate inattention, motor activity and impulsivity that emerges early in development and causes impairment in social and academic functioning. ADHD is described as a multifactorial disease, with a well studied genetic vulnerability, and early environmental factors also playing an important role in the development and course of the disorder. Current aetiological models emphasize interaction between genes and environment. The concept of attachment, as proposed by John Bowlby, reflects quality of early interactions, and should therefore be considered as an early developmental factor. First, clinical findings emphasize similitude between both disorders; emotional dysregulation is an important feature in reactive attachment disorder as well as in ADHD. Emotion regulation is highly related to attachment security in young children and could play a part in the development of early attention processes. Moreover, difficult temperament is associated with higher risk for ADHD on the one hand, and can disturb the process of attachment on the other. Parental caregiving - including maternal sensitivity, positive parenting practices - is a main factor involved in the development of attachment, and has shown to be associated with better outcomes in ADHD children, especially with less oppositional/conduct disorders. Second, the aim of our review is to present clinical studies that have looked for a link between ADHD and attachment: the type of attachment could play a part in the course of the disorder: insecure and disorganised attachment types tend to be associated with a higher risk of externalised behaviors in children. For ADHD, this effect seems to be weaker than for other externalised disorders, and has been shown only in populations of at-risk children. Clinical studies also raise the question of possible links between reactive attachment disorder and ADHD. In children suffering
This presentation describes the development of attachment between adopted children and their adoptive parents with a focus on the particular issues seen in international adoptions. The questions of settling in, trauma in the country of origin, and the motivations of the adoptive parents will be discussed. Diagnosis and various psychopathological manifestations will be examined, as will outpatient and inpatient modes of therapy. The treatment of children of various ages will be covered along with the necessity for intensive counseling and psychotherapy for the adoptive parents. This will enable the parents to work through early trauma, which will give them and their adopted child the basis for developing healthy attachment patterns. This in turn will enable the child to mature and integrate into society. Possibilities of prevention are discussed. Many of the approaches discussed here regarding attachment and adoption may be applied to foster children and their foster parents.

Recent studies based on J. Bowlby's (1969/1982) attachment theory reveal that both dispositional and experimentally enhanced attachment security facilitate cognitive openness and empathy, strengthen self-transcendent values, and foster tolerance of out-group members. Moreover, dispositional attachment security is associated with volunteering to help others in everyday life and to unselfish motives for volunteering. The present article reports 5 experiments, replicated in 2 countries (Israel and the United States), testing the hypothesis that increases in security (accomplished through both implicit and explicit priming techniques) foster compassion and altruistic behavior. The hypothesized effects were consistently obtained, and various alternative explanations were explored and ruled out. Dispositional attachment-related anxiety and avoidance adversely influenced compassion, personal distress, and altruistic behavior in theoretically predictable ways. As expected, attachment security provides a foundation for care-oriented feelings and caregiving behaviors, whereas various forms of insecurity suppress or interfere with compassionate caregiving.

This study analyzed personality disorders in a group of 33 securely and 51 insecurely attached child molesters. A total of 51 child molesters were selected from a community based educational training program, and the other group was selected from a Belgian prison (n = 33). Research shows that adult attachment styles and personality disorders share a common underlying structure. It is remarkable that very little is known about differences between securely and insecurely attached child molesters. In this study, the authors found that the schizoid personality disorder differed between securely and insecurely attached child molesters. These findings have implications for the aetiology and treatment of child molesters. Future research is necessary to determine patterns of attachment in relationship to personality disorders.

In this article, we report the results of 2 studies that were conducted to investigate whether adult attachment theory explains employee behavior at work. In the first study, we examined the structure of a measure of adult attachment and its relations with measures of trait affectivity and the Big Five. In the second study, we examined the relations between dimensions of attachment and emotion regulation behaviors, turnover intentions, and supervisory reports of counterproductive work behavior and organizational citizenship behavior. Results showed that anxiety and avoidance represent 2 higher order dimensions of attachment that predicted these criteria (except for counterproductive work behavior) after controlling for individual difference variables and organizational commitment. The implications of these results for the study of attachment at work are discussed.

We found that non-attached aggregates from stationary-phase cultures have comparable growth rates to surface attached biofilms. The growth rate estimations indicated that, independently...... the physiological states of the aggregates and particular matrix components. Bacterial surface-attachment and subsequent biofilm formation are considered hallmarks of the capacity of microbes to cause persistent infections. We have observed non-attached aggregates in the lungs of cystic fibrosis patients; otitis...

Dengue fever is caused by a flavivirus. This infection is endemic in the tropics and warm temperate regions of the world. Ocular manifestations of dengue fever include subconjunctival, vitreous, and retinal haemorrhages; posterior uveitis; optic neuritis; and maculopathies, haemorrhage, and oedema. However anterior ischemic optic neuropathy is a rare presentation. Optic nerve ischemia most frequently occurs at the optic nerve head, where structural crowding of nerve fibers and reduction of the vascular supply may combine to impair perfusion to a critical degree and produce optic disc oedema. Here we present a case of anterior ischemic optic neurapathy associated with dengue fever.

Anterior sacral meningocele (ASM) is a rare congenital disorder involving herniation of the dural sac through a defect in the anterior surface of the sacrum. We report the case of a young patient with an enormous ASM that simulated bladder retention in terms of symptoms as well as on physical examination and at ultrasonography. After introducing a catheter that excluded urinary retention, computed tomography (CT) scan and magnetic resonance imaging (MRI) showed the ASM. The patient underwent surgical repair of the ASM through a sacral laminectomy and recovered normal lower urinary tract function. Copyright © 2013 Elsevier Inc. All rights reserved.
Full Text Available Background. Adolescence represents a challenging transitional period where changes in biological, emotional, cognitive and social domains can increase the risk of developing internalised problems including subthreshold depression. Adolescent-parent attachment style, perceived support and family functioning may increase risk for depressive symptoms or may reduce such risk. Adolescent-parent attachment, adolescent-perceived support from parents and family functioning were examined as correlates of depressive symptom presentation within this age group. Methods. Participants included a maternal parent and an adolescent (65.5% female from each family. Adolescents were in Grade 7 (n=175 or Grade 10 (n=31. Data were collected through home interviews. The Self-Report of Family Inventory (SFI, Experiences of Close Relationships Scale (ECR, Network of Relationships Inventory (NRI, Children’s Depression Inventory (CDI and Child Behavior Checklist (CBCL were used to assess depression, parental support and attachment. Results. Two models were examined: one with adolescent report of depressive symptoms as the outcome and a second with parent report of adolescent internalising symptoms as the outcome. The model predicting adolescent-reported depressive symptoms was significant with older age, higher levels of avoidant attachment, and higher levels of youth-reported dysfunctional family interaction associated with more depressive symptomatology. In the model predicting parent report of adolescent internalising symptoms only higher levels of dysfunctional family interaction, as reported by the parent, were associated with higher levels of internalising symptoms. Conclusion. Positive family communication, cohesion and support predictive of a secure parent-adolescent attachment relationship reduced the risk of a depressive symptom outcome. Secure adolescents were able to regulate their emotions, knowing that they could seek out secure base attachment relations

Full Text Available Background: Pregnant women with insecure attachment style are at high risk of psychiatric disorders. Since emotions are the first coordinators of attachment behavior, emotion regulation training can alter maternal attachment style. In this study, we aimed to evaluate the effects of emotion regulation training on the attachment styles of primiparous pregnant women with insecure attachment style. Aim: This study aimed to evaluate the effects of training programs on the headache of patients after spinal anesthesia. Method: This randomized, clinical trial on 40 primiparous pregnant women with age range of 30-34 years, who were referred to healthcare centers of Mashhad, Iran, during 2014. The data collection instrument was Revised Adult Attachment Scale (RAAS. The participants were assigned to intervention and control groups. A training program was implemented on emotion regulation based on dialectical behavior therapy (DBT for the intervention group. After delivery, RAAS was completed by the mothers again. The control group only received the routine care. To analyze the data, Chi-square and independent t-test were run using SPSS, version 15. Results: Mean ages of the mothers in the intervention and control groups were 26.9±4.04 and 27.5±3.5 years, respectively. According to the results of independent t-test, the difference between the groups was non-significant (P=0.77. The groups were analogous in terms of attachment style pre-intervention. After the intervention, independent t-test did not reflect any significant differences between the groups regarding avoidant (P=0.37 and anxious (P=0.11 attachment styles. However, mean score for secure attachment style was significantly enhanced (P=0.01. Implications for Practice: Our findings revealed that implementation of emotion regulation training increased secure attachment scores. Thus, implementing emotion regulation training program is recommended as part of a program for pre-natal care in healthcare
Full Text Available Background Conventional dentures in edentulous patients show some limitations due to the lack of retention, support and stability thus resulting in difficulty to chew. The modern implantology allows to use different implant overdentures and different attachment systems. The selection of the attachment by practitioners is mainly influenced by the clinical experience or technical preferences. Aims The aim of the present review is to provide an adequate background to the clinicians, in order to select the prosthetic attachments according to the current literature. The mechanical attachments have been compared to the magnetic devices, with the aim to guide the decision of the practitioners. Methods Articles topics selection was based on the use of magnetic attachments in dentistry and the comparison between them and mechanical connectors. The databases used were PubMed/MEDLINE, Google Scholar and ISI Web of Science. A critical evaluation of the selected paper has been made to choose the ones that matched the inclusion criteria. Results Nowadays, few studies have compared different attachments in a manner useful for clinical decision-making. The main problem limiting long-term durability of magnetic attachments in the oral fluid is the poor corrosion resistance of permanent magnets and the consequent leaching of cytotoxic ions. Conclusion Magnetic attachments in comparison with other attaching systems can be useful in patients with special needs, in patients with limited interocclusal space, or in patients with neuromuscular limitations, thanks to the automatic reseating properties. However, it’s important to highlight that the mechanical attachments still represent the best choice in common conditions requiring dental prostheses.

The physical mechanism of lightning attachment to grounded structures is one of the most important issues in lightning physics research, and it is the basis for the design of the lightning protection systems. Most of what is known about the attachment process comes from leader propagation models that are mostly based on laboratory observations of long electrical discharges or from observations of lightning attachment to tall structures. In this paper we use high-speed videos to analyze the attachment process of downward lightning flashes to an ordinary residential building. For the first time, we present characteristics of the attachment process to common structures that are present in almost every city (in this case, two buildings under 60 m in São Paulo City, Brazil). Parameters like striking distance and connecting leaders speed, largely used in lightning attachment models and in lightning protection standards, are revealed in this work.Plain Language SummarySince the time of Benjamin Franklin, no one has ever recorded high-speed video images of a lightning connection to a common building. It is very difficult to do it. Cameras need to be very close to the structure chosen to be observed, and long observation time is required to register one lightning strike to that particular structure. Models and theories used to determine the zone of protection of a lightning rod have been developed, but they all suffer from the lack of field data. The submitted manuscript provides results from high-speed video observations of lightning attachment to low buildings that are commonly found in almost every populated area around the world. The proximity of the camera and the high frame rate allowed us to see interesting details that will improve the understanding of the attachment process and, consequently, the models and theories used by lightning protection standards. This paper also presents spectacular images and videos of lightning flashes connecting lightning rods that
Attachment theory promoted an impressive body of research on the psychic developmental processes, resulting in studies on both typical and atypical development. Much of the diffusion of the attachment theory in the clinical field was related to the design of reliable instruments to evaluate the organization of attachment in infancy as well as in adulthood. Until recently, the lack of a suitable instrument to assess attachment in middle childhood as well as in adolescence hindered the expansion of research in these developmental phases during which the parent-child relationship takes on a different, albeit still crucial, role. The Child Attachment Interview (CAI), a measure that was recently designed to assess attachment at a representational level in middle childhood and adolescence, filled the measurement gap. The aim of the current review was to summarize previous empirical investigations concerning CAI in order to (a) provide an overview of the state of current research, (b) identify unanswered questions, and (c) propose future research directions. A narrative review was conducted to map the current research findings by searching for the term "Child Attachment Interview" in the Medline, Scopus, Web of Science, and PsychINFO databases, followed by a search in Mendeley. Limits were set to exclude dissertations, chapters in books, and qualitative or theoretical papers, while empirical studies were included if they used the CAI and were published in English language, peer-reviewed journals by July, 2016. The review, which ultimately included 39 studies meeting the criteria, showed that the CAI is a reliable instrument to assess attachment organization in clinical and non-clinical samples, thus providing a worthwhile contribution to the investigation of the influence of the parent-child relationship beyond infancy and early childhood. Nevertheless, the review pointed out a number of relevant open issues, the most critical of which concerned the CAI coding and

To evaluate and compare retentive properties of O-ring and Locator attachments for implant-retained maxillary overdentures. Four implant analogs were inserted in canine and second premolar areas of an acrylic edentulous maxillary model. A metal-reinforced experimental acrylic overdenture was constructed and connected to the analogs using either O-ring (group I) or Locator (group II) attachments. Locators were divided into 3 subgroups according the degree of retention of the patrix nylon insert: Locator extra-light retention (group IIa), Locator light retention (group IIb), and Locator medium retention (group IIc). Vertical and oblique (lateral, anterior, and posterior) dislodging forces were measured at the beginning of the study (initial retention) and after 540 cycles of denture insertion and removal (final retention). For vertical, lateral, and anterior dislodging, group IIc recorded the highest initial and final retention, and group I recorded the lowest retention. For posterior dislodging, group I recorded the highest retention, and group IIa recorded the lowest retention. For group II, vertical dislodging recorded the highest initial and final retention, and lateral dislodging recorded the lowest retention. For group I, posterior dislodging recorded the highest initial and final retention, and lateral dislodging recorded the lowest retention. For all dislodging forces (except posterior dislodging), the highest retention loss was recorded in group I, and the lowest retention loss was recorded in group IIa. Locator medium attachment was associated with favorable retention during axial (vertical) and nonaxial (anterior and lateral) dislodging compared to other types of Locator inserts and O-ring attachments after a simulated 6-month period of overdenture use. © 2016 by the American College of Prosthodontists.

Previous research on attachment theory has focused on mean differences in level of self-esteem among people with different attachment styles. The present study examines the associations between attachment styles and different bases of self-esteem, or contingencies of self-worth, among a sample of 795 college students. Results showed that attachment security was related to basing self-worth on family support. Both the preoccupied attachment style and fearful attachment style were related to basing self-worth on physical attractiveness. The dismissing attachment style was related to basing self-worth less on others' approval, family support, and God's love.

To describe the surgical technique and report the outcomes of patients treated with microkeratome-assisted superficial anterior lamellar keratoplasty for anterior stromal corneal opacities developing after penetrating keratoplasty (PK). All patients with post-penetrating keratoplasty anterior stromal opacities treated with microkeratome-assisted superficial anterior lamellar keratoplasty between July 2005 and June 2007 were reviewed. A 130-μm superficial keratectomy was performed, followed by the placement of an appropriately sized donor graft, which was secured with overlay sutures. Refraction, corneal topography, and uncorrected and best-corrected visual acuities (UCVA, BCVA, respectively) were noted at each examination. Nine eyes of 8 consecutive patients were identified. Causes of anterior stromal opacities included dystrophy recurrence (n = 3), post-photorefractive keratectomy haze (n = 2), and scarring after stromal melt (n = 4). BCVA improved in all 9 eyes at final follow-up, and 7 of 9 eyes achieved ≥20/40 within the first month. Average follow-up period was 28 ± 3.9 months. Refractive astigmatism also improved by an average of 0.7 diopters. Superficial anterior lamellar keratoplasty is a viable and effective alternative to repeat PK in treating anterior stromal scars. It avoids open-globe surgery and exposure to endothelial rejection associated with repeat PK, and visual rehabilitation is considerably quicker.
Full Text Available A novel postauricular revolving door island flap and cartilage graft combination was employed to correct a large defect on the anterior ear of an 84-year-old man who underwent Mohs micrographic surgery for an antihelical squamous cell carcinoma. The defect measured 4.6 × 2.4 cm and spanned the antihelix, scapha, a small portion of the helix, and a large segment of underlying cartilage, with loss of structural integrity and anterior folding of the ear. The repair involved harvesting 1.5 cm2 of exposed cartilage from the scaphoid fossa and then sculpting and suturing it to the remnant of the antihelical cartilage in order to recreate the antihelical crura. The skin of the posterior auricle was then incised just below the helical rim and folded anteriorly to cover the cartilage graft. The flap remained attached by a central subcutaneous pedicle, and an island designed using the full-thickness defect as a stencil template was pulled through the cartilage window anteriorly to resurface the anterior ear. This case demonstrates the use of the revolving door flap for coverage of large central ear defects with loss of cartilaginous support and illustrates how cartilage grafts may be used in combination with the flap to improve ear contour after resection.
Full Text Available A dual task of attachment priming and memory recognition was proposed to explore the effect of adult attachment styles on the incidental memory for emotional words. Subjects completed an attachment priming task which intends to activate internal working model of attachment by describing attachment-related scenes, and then an incidental memory recognition test of words which differ in emotional meaning and relevance of attachment styles. Signal detection theory was used to compare the discriminability index and decision criterion of emotional words in subjects of different attachment style. Results showed that subjects with secure attachment styles performed better than insecure-attached subjects in the memory recognition test, in terms of higher hit rate, lower false alarm rate, and higher discriminability index. We extended the influence of attachment styles on cognition to lower level of incidental memory, not just on higher cognitive level with emotional arousal as suggested by previous research.

During preschool and early school age attachment quality can be assessed by different means: at the behavioral level by the Strange Situation (SS), at the representational level by semiprojective methods using story stems or pictures. Both methods gain access to different levels of a theoretically assumed inner working model of attachment, in which attachment at the behavioral level is supposed to be person specific, attachment at the representational level generalized. This study aimed at analyzing whether attachment behavior to mother and father is associated, and how it is linked to the generalized attachment representation. It was also examined whether in the case of no association between mother and father attachment behavior towards the major attachment figure is linked to the attachment representation. In the Duesseldorf study 67 children aged 5 years were observed in the SS with mother, 31 of them also in the SS with father. At the age of 6.5 years an attachment story completion task was conducted. When person specific attachment to mother and father was congruent (SS secure n=6, or insecure n=8) the attachment representation was consistent as well, when father and mother attachment were discrepant no association with attachment representation could be found. The findings did not confirm a stronger influence of the major attachment figure on the formation of the attachment representation.

Resent advances have led to the reexamination of the intraosseous pathway of the chorda tympani a few years ago and they stated that the nerve never enters the mandibular fossa and its exit the skull base in the sphenopetrosal fissure. In our report, 58 temporal bones were investigated after maceration and formalin fixation in order to understand the development of the anterior chordal canal. Our study revealed that the chorda tympani leaves the tympanic cavity through the tympanosquamosal fissure before formation of the anterior chordal canal of Huguier. This canal is situated parallel to and in front of the musculotubal canal and formed by the processus inferior tegminis tympani and the sphenoid bone between the second and fifth years of age. Prior to the age of 2, only the exit of the bony canal exists which is gradually followed by the appearance of a groove in the growing processus inferior tegminis tympani. The borders of the groove elevate and develop to upper and lower plates which lengthen with similar plates of the sphenoid bone, completing the anterior chordal canal by the fifth postnatal year. The entrance of the canal develops above the petrotympanic fissure and similar to the canal itself, it is also completely formed in the fifth year. In case of an incomplete development the anterior chordal canal remains partially opened laterally which might allow the head of the mandibula to effect the chorda tympani mechanically causing Costen's syndrome.

In order to prevent anterior cruciate ligament injuries it is necessary to define risk factors and to analyze the most frequent causes of injuries--that being the aim of this study. The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen), 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%), injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%), then in handball players (22%), basketball players (13%), volleyball players (8%), martial arts fighters (4%). However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players). Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%), at landing after the jump or when changing direction of movement (75%) without a contact with other competitors, on dry surfaces (79%), among not so well prepared sportsmen.

To present the experience of the Orthopedics Service PEMEX South Central Hospital in the management of anterior unidirectional shoulder instability with an arthroscopic technique consisting of capsular retensioning either combined with other anatomical repair procedures or alone. Thirty-one patients with anterior unidirectional shoulder instability operated-on between January 1999 and December 2005 were included. Fourteen patients underwent capsular retensioning and radiofrequency, and in 17 patients, capsular retensioning was combined with suture anchors. Patients with a history of relapsing glenohumeral dislocations and subluxations, with anterior instability with or without associated Bankart lesions were selected; all of them were young. The results were assessed considering basically the occurrence of instability during the postoperative follow-up. No cases of recurring instability occurred. Two cases had neuroma and one experienced irritation of the suture site. Six patients had residual limitation of combined lateral rotation and abduction movements, of a mean of 10 degrees compared with the healthy contralateral side. The most frequent incident was the leak of solutions to the soft tissues. Capsular retensioning, whether combined or not with other anatomical repair techniques, has proven to result in a highly satisfactory rate of glenohumeral stabilization in cases of anterior unidirectional instabilities. The arthroscopic approach offers the well-known advantages of causing less damage to the soft tissues, and a shorter time to starting rehabilitation therapy and exercises.

Three male and two female patients with anorgasmia and dissociated sensory loss due to an anterior spinal cord syndrome are described. Clinical, neurophysiological and quantitative sensory evaluation revealed preservation of the large fibre dorsal column functions from the lumbosacral segments with concomitant severe dysfunction or absence of the small fibre neospinothalamic mediated functions. These findings indicate a role for the spinothalamic system in orgasm.

Attachment researchers have proposed that the attachment, caregiving, and sexual behavioral systems are interrelated in adult love relationships (Mikulincer & Shaver, 2007 ). This study examined whether aspects of partners' caregiving (proximity, sensitivity, control, compulsive caregiving) mediated the association between their attachment insecurities (anxiety and avoidance) and each other's sexual satisfaction in two samples of committed couples (Study 1: 126 cohabiting or married couples from the general community; Study 2: 55 clinically distressed couples). Partners completed the Experiences in Close Relationships measure (Brennan, Clark, & Shaver, 1998 ), the Caregiving Questionnaire (Kunce & Shaver, 1994 ), and the Global Measure of Sexual Satisfaction (Lawrance & Byers, 1998 ). Path analyses based on the actor-partner interdependence model (APIM) revealed that caregiving proximity mediated the association between low attachment avoidance and partners' sexual satisfaction in distressed and nondistressed couples. Sensitivity mediated this association in nondistressed couples only. Control mediated the association between men's insecurities (attachment-related avoidance and anxiety) and their partners' low sexual satisfaction in nondistressed couples. Attachment anxiety predicted compulsive caregiving, but this caregiving dimension was not a significant mediator. These results are discussed in light of attachment theory and their implications for treating distressed couples.

John Bowlby defined offspring-parent attachment as a relationship in which an infant or child uses one or a few preferred adults as a secure base from which to explore and as a haven of safety. He defined attachment security in terms of confidence in the adult's availability and responsiveness and the smooth organization of exploration and proximity seeking. Developmental psychologists have found this perspective productive in both observational and laboratory research. At the same time, they emphasize that such a construct cannot be operationalized in terms of one or a few behaviors. Instead, naturalistic observations of human infant attachment typically employ the Q-sort method to develop the Attachment q-set (AQS), 90 behaviorally descriptive items sorted in terms of how characteristic each item is of the infant's typical behavior. Meta-analyses of research using the AQS attest to its reliability and validity. This article reports an adaptation of the AQS to the task of assessing infant attachment security in nonhuman primates and illustrates its use. The availability of comparable measures of attachment security will contribute to an expanded understanding of patterns of attachment behavior in nonhuman primate societies and will facilitate interaction between comparative and developmental psychologists. © 2010 Wiley-Liss, Inc.

Despite evidence that parents’ attachment is associated with children’s memory, less is known about the mechanisms underlying this association or the contexts in which the association is most meaningful. The present study examined whether parents’ attachment predicted children’s memory for stories about attachment-related topics, whether the cohesiveness of children’s stories mediated the association between attachment and memory, and whether the association varied by interview support at retrieval. Five- to 6-year-olds completed attachment-relevant stories while parents provided information about their romantic attachment. Children’s stories were coded for cohesiveness. A week later, children’s memory for their stories was tested by either a supportive or non-supportive interviewer. When the interview was non-supportive, greater parental avoidance was associated with poorer memory, whereas when the interview was supportive, greater parental avoidance was associated with fewer errors. Findings provide insight into the context under which parents’ attachment is most influential in shaping children’s memory. PMID:29308006

Many scholars have proposed that parent-child attachment security should favor child sleep. Research has yet, however, to provide convincing support for this hypothesis. The current study used objective measures of sleep and attachment to assess the longitudinal links between mother-child attachment security and subsequent sleep, controlling for child dependency. Sixty-two middle-class families (30 girls) were met twice, when children were 15 months (Wave 1; W1) and 2 years of age (Wave 2; W2). At W1, mother-child attachment was assessed with the observer version of the Attachment Q-Sort. At W2, children wore an actigraph monitor for 72 hr. Results indicated that children more securely attached to their mothers subsequently slept more at night and had higher sleep efficiency, and these predictions were not confounded by child dependency. These findings suggest a unique role for secure attachment relationships in the development of young children's sleep regulation, while addressing methodological issues that have long precluded consensus in this literature. © 2015 The Society for Research in Child Development, Inc.

Gradient materials play a significant role in the creation of artificial implants due to their potential to reduce stress concentration when two or more structures with different mechanical properties are joined together, e . g . , tendon, a fibrous protein that connects the soft and hard muscle tissues in our body. We employ free radical polymerization to synthesize random copolymers containing 90% of N-isopropyl acrylamide (NIPAAm), 5% photo-active methacrylyloxybenzophenone (MABP) and 5% thermally-active styrenesulfonylazide (SSAz) crosslinkers. The presence of MABP and SSAz facilitates adjusting gel density on a flat support in two orthogonal directions by spatially and independently controlling UV dosage and temperature. The swelling behavior (α) of the gels in water and methanol is examined using a spectroscopic ellipsometry and the degree of swelling depends on the extent of crosslinking that ranges from α = 1-1.2 (highly crosslinked gels) to α = 4-5 (loosely crosslinked gels). We compare the network properties surface-attached gels and un-attached identical counterparts and confirm that the linear swelling ratio of surface-attached networks is higher than that of the corresponding un-attached gels.

Full Text Available The Roseobacter clade is a key group of bacteria in the ocean exhibiting diverse metabolic repertoires and a wide range of symbiotic life-styles. Many Roseobacters possess remarkable capabilities of attachment to both biotic and abiotic surfaces. When attached to each other, these bacteria form multi-cellular structures called rosettes. Phaeobacter inhibens, a well-studied Roseobacter, exhibits various cell sizes and morphologies that are either associated with rosettes or occur as single cells. Here we describe the distribution of P. inhibens morphologies and rosettes within a population. We detect an N-acetylglucosamine-containing polysaccharide on the poles of some cells and at the center of all rosettes. We demonstrate that rosettes are formed by the attachment of individual cells at the polysaccharide-containing pole rather than by cell division. Finally, we show that P. inhibens attachment to abiotic surfaces is hindered by the presence of DNA from itself, but not from other bacteria. Taken together, our findings demonstrate that cell adhesiveness is likely to play a significant role in the life cycle of P. inhibens as well as other Roseobacters.

Full Text Available A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture was performed. On the first postoperative day, slit-lamp examination revealed corneal edema, 3+ cells in the anterior chamber and an irregular pupil. According to these findings, the diagnosis was anterior segment ischemia. Treatment with 0.1/5 mL topical dexamethasone drops (16 times/day, cyclopentolate hydrochloride drops (3 times/day and 20 mg oral fluocortolone (3 times/day was initiated. After 1 week of treatment, corneal edema regressed and the anterior chamber was clean. Topical and systemic steroid treatment was gradually discontinued. At postoperative 1 month, the patient was orthophoric and there were no pathologic symptoms besides the irregular pupil. Anterior segment ischemia is one of the most serious complications of strabismus surgery. Despite the fact that in most cases the only remaining sequel is an irregular pupil, serious circulation deficits could lead to phthisis bulbi. Clinical properties of anterior segment ischemia should be well recognized and in especially risky cases, preventative measures should be taken.

In the last years, basic research and arthroscopic surgery, have improved our understanding of shoulder anatomy and pathology. It is a fact that arthroscopic treatment of shoulder instability has evolved considerably over the past decades. The aim of this paper is to present the variety of pathologies that should be identified and treated during shoulder arthroscopy when dealing with anterior shoulder instability cases. A review of the current literature regarding arthroscopic shoulder anatomy, anatomic variants, and arthroscopic findings in anterior shoulder instability, is presented. In addition, correlation of arthroscopic findings with physical examination and advanced imaging (CT and MRI) in order to improve our understanding in anterior shoulder instability pathology is discussed. Shoulder instability represents a broad spectrum of disease and a thorough understanding of the pathoanatomy is the key for a successful treatment of the unstable shoulder. Patients can have a variety of pathologies concomitant with a traditional Bankart lesion, such as injuries of the glenoid (bony Bankart), injuries of the glenoid labrum, superiorly (SLAP) or anteroinferiorly ( e.g . anterior labroligamentous periosteal sleeve avulsion, and Perthes), capsular lesions (humeral avulsion of the glenohumeral ligament), and accompanying osseous-cartilage lesions (Hill-Sachs, glenolabral articular disruption). Shoulder arthroscopy allows for a detailed visualization and a dynamic examination of all anatomic structures, identification of pathologic findings, and treatment of all concomitant lesions. Surgeons must be well prepared and understanding the normal anatomy of the glenohumeral joint, including its anatomic variants to seek for the possible pathologic lesions in anterior shoulder instability during shoulder arthroscopy. Patient selection criteria, improved surgical techniques, and implants available have contributed to the enhancement of clinical and functional outcomes to the

Periodontal diseases are infectious polymicrobial inflammatory diseases that lead to destruction of the periodontal ligament, gingiva, and alveolar bone. Sequential colonization of a broad range of bacteria, including Fusobacterium nucleatum and Porphyromonas gingivalis, is an important phenomenon in this disease model. F. nucleatum is a facultative anaerobic species thought to be a key mediator of dental plaque maturation due to its extensive coaggregation with other oral bacteria, while P. gingivalis is an obligate anaerobic species that induces gingival inflammation by secreting various virulence factors. The formation of a bacterial complex by these two species is central to the pathogenesis of periodontal disease. Reactive oxygen species (ROS) are produced during bacterial infections and are involved in intracellular signaling. However, the impact of oral bacteria-induced ROS on the ecology of F. nucleatum and P. gingivalis has yet to be clarified. In the present study, we investigated ROS production induced in primary human oral cells by F. nucleatum and P. gingivalis and its effect on the formation of their bacterial complexes and further host cell apoptosis. We found that in primary human gingival fibroblasts (GFs), two NADPH oxidase isoforms, NOX1 and NOX2, were activated in response to F. nucleatum infection but not P. gingivalis infection. Accordingly, increased NADPH oxidase activity and production of superoxide anion were observed in GFs after F. nucleatum infection, but not after P. gingivalis infection. Interestingly, in NOX1, NOX2, or NOX1/NOX2 knockdown cells, the number of P. gingivalis decreased when the cells were coinfected with F. nucleatum. A similar pattern of host cell apoptosis was observed. This implies that F. nucleatum contributes to attachment of P. gingivalis by triggering activation of NADPH oxidase in host cells, which may provide an environment more favorable to strict anaerobic bacteria and have a subsequent effect on apoptosis of

Townsend's attached eddy hypothesis forms the basis of an established model of the logarithmic layer in wall-bounded turbulent flows in which this inertially dominated region is characterised by a hierarchy of geometrically self-similar eddying motions that scale with their distance to the wall. The hypothesis has gained considerable support from high Reynolds number measurements of the second-order moments of the fluctuating velocities. Recently, Meneveau and Marusic ["Generalized logarithmic law for high-order moments in turbulent boundary layers," J. Fluid Mech. 719, R1 (2013)] presented experimental evidence that all even-ordered moments of the streamwise velocity will exhibit a logarithmic dependence on the distance from the wall. They demonstrated that this was consistent with the attached eddy hypothesis, so long as the velocity distribution is assumed to be Gaussian (which allows the use of the central limit theorem). In this paper, we derive this result from the attached eddy model without assuming a Gaussian velocity distribution, and find that such logarithmic behaviours are valid in the large Reynolds number limit. We also revisit the physical and mathematical basis of the attached eddy hypothesis, in order to increase rigour and minimise the assumptions required to apply the hypothesis. To this end, we have extended the proof of Campbell's theorem to apply to the velocity field corresponding to a forest of variously sized eddies that are randomly placed on the wall. This enables us to derive all moments of the velocity in the logarithmic region, including cross-correlations between different components of the velocity. By contrast, previous studies of the attached eddy hypothesis have considered only the mean velocity and its second order moments. From this, we obtain qualitatively correct skewnesses and flatnesses for the spanwise and wall-normal fluctuations. The issue of the Reynolds number dependence of von Kármán's constant is also addressed.

Recently studies examining the colonization of Clostridial pathogens on agar and human tissue culture cells, demonstrated that (C. sporogenes ATCC 3584, C. difficile ATCC 43594 [patient isolate], C. difficile ATCC 9689 [non-clinical], C. clostridioforme [patient isolate]) bacterial spores (endospores) of the genus Clostridia have an outer membrane that becomes responsive at activation and exhibits extensions of the exosporial membrane that facilitate and maintain spore attachment to a nutritive substrate during germination and initial outgrowth of the newly developed bacterial cell. Therefore this attachment phenomenon plays an important role in insuring bacterial colonization of a surface and the initial stages of the infective process. To see if other non-clinical members of this genus also have this ability to attach to a substrate or food-source during spore germination, and how this attachment process in environmental thermophiles compares to the clinical paradigm (in relation to time sequence, exosporial membrane structure, type of attachment structures, composition of the membrane etc...), sediment samples were collected in sterile transport containers at 4 geothermal sites at Yellowstone National Park in Wyoming. Because spore forming bacteria will produce spores when conditions are unfavorable for growth, the samples were sealed and stored at 4 C. After 8 months the samples were screened for the presence of spores by light microscope examination using malachite green/safranin, and traditional endospores were identified in significant quantities from the Terrace Spring site (a 46 C lake with bacterial mats and a rapidly moving run-off channel leading to a traditional hot spring). The highest spore population was found in the top sediment and benthic water of the run-off channel, pH 8.1.
Full Text Available Purpose: The aim of the present study was to compare the periosteal fenestration (PF and free mucosal graft (FMG techniques in mandibular anterior region to increase the vestibular depth. Methodology: A total of 20 systemically healthy cases (10 patients in each group with shallow vestibular depth and reduced width of attached gingiva in lower anterior region were included in the present study. Clinical parameters recorded included Gingival index (GI, Plaque index (PI, Oral hygiene index simplified (OHI S, Vestibular depth (VD, width of attached gingiva and post operative discomfort. Findings: The results at the end of 3 months showed that the mean GI, PI, OHI S decreased significantly and remained low throughout the study period. The mean gain in percentage of vestibular depth at the end of 3 months for group 1(PF was 48.4% with relapse of 7.2% from the baseline. For group 2 (FMG, the mean gain in percentage of vestibular depth at the end of 3 months for was 50% with relapse of 6.2% from the baseline. The mean gain in percentage of attached gingiva at 3 months for group 1 and 2 was 65.9% and 74%, respectively. In comparison of group 1 and 2, group 2 showed better results in terms of increasing the vestibular depth and attached gingiva than group 1 although the intergroup comparison was not statistically significant. Conclusion: When aim of the clinician is to treat a patient with shallow vestibule together with reduced width of attached gingiva, the use of periosteal fenestration yields similar results to that of FMG.

To report the results and effectiveness of anterior stromal puncture for contact lens-intolerant keratoconus patients with subepithelial fibrotic nodules. Nine eyes of nine keratoconus patients who were rigid gas-permeable contact lenses (RGP)-intolerant due to subepithelial nodular scars were included in this study. The nine patients were enrolled in the study between March 2008 and December 2008. After confirming nodular elevation from slit-lamp biomicroscopy, the area where the epithelium of nodular scars had sloughed was punctured by anterior stromal puncture using a 26-gauge needle attached to a 1-ml syringe under slit-lamp biomicroscopy. The RGPs of all patients were refitted around 4 weeks after the puncture. Five of the nine patients were male, and the average patient age was 29.6 years (SD ± 5.22 years). Mean follow-up time was 13.7 months (SD ± 4.8 months), and the epithelial defect healed in 1.4 days on average. After the puncture, four of nine patients presented with a recurrent erosion of the nodule during follow-up and needed a second puncture. All the patients showed good contact lens tolerance and satisfactory contact lens fit. No complications such as corneal perforation or keratitis developed. Anterior stromal puncture using a 26-gauge needle can be a successful and effective method to induce corneal epithelium and Bowman's layer reattachment. It can be used as an outpatient procedure to improve RGP tolerance in patients with keratoconus with elevated subepithelial nodules.
Full Text Available The anterior cervical spine surgery is a common procedure to stabilize vertebrae damaged by various diseases. The plates and screws are usually used in the spine fixation. This kind of instrumentation may detach from the bones which is a rare but well-known complication. A 77-year-old male presented to the otorhinolaryngology department with throat pain, choking, and dysphagia. At first the angioedema was diagnosed and he was treated conservatively. The endoscopy revealed laryngeal edema, being more defined on the right side with right vocal fold paresis. CT scans showed the stabilizing plate with two screws attached tightly and the back-out of the third screw toward soft tissue of the neck. In the meantime, his condition deteriorated and he needed tracheotomy. In few days the surgical removal of the dislocated screw was performed successfully. Although two-month follow-up reported no obstruction of the larynx, the vocal folds paresis with gradual functional improvement was observed. Long-term complication of anterior spine surgery sometimes may suggest laryngeal angioedema at first. If the conservative treatment is ineffective and there is a history of anterior spine surgery, the clinicians should consider the displacement of the plate or screws in differential diagnosis.

The aim of this study was to compare single and double anterior portal techniques in the arthroscopic treatment of traumatic anterior shoulder instability. A total of 91 cases who underwent arthroscopic Bankart repair for anterior shoulder instability were reviewed. The patients were divided into 2 groups as Group 1 (47 male and 2 female; mean age: 25.8 ± 6.8) for arthroscopic single anterior portal approach and Group 2 (41 male and 1 female; mean age: 25.4 ± 6.6) for the classical anterior double portal approach. The groups were compared for clinical scores, range of motion, analgesia requirement, complications, duration of surgery, cost and learning curve according to a short questionnaire completed by the relevant healthcare professionals. No statistically significant difference was found between the 2 groups in terms of pre-operative and post-operative Constant and Rowe Shoulder Scores, range of motion and complications (p > 0.05). In Group 2 patients, the requirement for post-operative analgesics was significantly higher (p portal anterior approach was preferred at a higher ratio (p = 0.035). The cost analysis revealed that the cost was 5.7% less for patients with a single portal. In the arthroscopic treatment of traumatic anterior shoulder instability accompanied by a Bankart lesion, the anterior single portal technique is as successful in terms of clinical results as the conventional double portal approach. The single portal technique has advantages such as less postoperative pain, a shorter surgical learning curve and lower costs. Level III, Therapeutic study.

Implant-supported overdenture is a reliable treatment option for the patients with edentulous mandible when they have difficulty in using complete dentures. Several options have been used for implant-supported overdenture attachments. Among these, bar attachment system has greater retention and better maintainability than others. SFI-Bar® is prefabricated and can be adjustable at chairside. Therefore, laboratory procedures such as soldering and welding are unnecessary, which leads to fewer errors and lower costs. A 67-year-old female patient presented, complaining of mobility of lower anterior teeth with old denture. She had been wearing complete denture in the maxilla and removable partial denture in the mandible with severe bone loss. After extracting the teeth, two implants were placed in front of mental foramen, and SFI-Bar® was connected. A tube bar was seated to two adapters through large ball joints and fixation screws, connecting each implant. The length of the tube bar was adjusted according to inter-implant distance. Then, a female part was attached to the bar beneath the new denture. This clinical report describes two-implant-supported overdenture using the SFI-Bar® system in a mandibular edentulous patient.

Although priming mental representations of attachment security reduces arousal, research has not examined the effect of attachment on the retrieval of emotionally arousing memories. This study investigated the effect of priming attachment security on the retrieval of emotional memories. Seventy-five participants viewed negative and neutral images, and two days later received either an attachment prime or a control prime immediately prior to free recall of the images. Two days later, participants reported how frequently they experienced intrusions of the negative images. The attachment group had less distress, and reported fewer subsequent intrusions than the control group. Attachment style moderated these effects such that individuals with an avoidant attachment style were not impacted by the attachment prime. These findings suggest that priming attachment security decreases distress during memory reactivation, and this may reduce subsequent intrusive memories. Copyright © 2017 Elsevier Inc.

A group of sex offenders (clinical group: n = 19) was compared to a nonclinical sample matched by age, years of education, and gender (control group A: n = 19) to verify a higher incidence of insecure attachment models among sex offenders. In addition, we tested whether sex offenders were characterized by specific childhood experiences, compared to control adults (control group B: n = 19) with the same secure/insecure attachment classification. Results showed significant differences between offenders and control adults on both the AAI continuous score and the distribution of the two-way attachment classifications. Furthermore, sex offenders reported more intense experiences of rejection by the father figure and abuse in the family context during early childhood compared to not offenders subjects with the same attachment classification. © 2014 American Academy of Forensic Sciences.

To re-evaluate the Segond fragment emphasizing those structures that attach to the fragment in patients with reported acute/subacute anterior cruciate ligament (ACL) injuries, and to clarify the nomenclature used to describe these structures. A search of databases of knee MR examinations over 4.5 years with reported ACL tears yielded 19,726 studies. Using strict exclusion criteria, a total of 146 MR studies with acute/subacute ACL tears were re-assessed with respect to the Segond fragment's size, shape, orientation, location, displacement, attaching soft tissue structures, and associated osseous and/or soft tissue injuries. Segond fractures were present in 1.25 % of reported acute/subacute ACL tears. The fragment measured 11.9 x 7.3 x 3.27 mm, being thin, ovoid, vertically oriented, situated anterolaterally along the proximal tibial epiphysis, posterior to Gerdy's tubercle and inferior to the lateral tibial plateau, and displaced up to 6 mm laterally. The attached structures were the meniscotibial component of the mid-third lateral capsular ligament (mt-MTLCL) in 58.9 %, both the mt-MTLCL and the posterior fibers of the ITB (pf-ITB) in 35.6 %, and the pf-ITB in 5.48 % of cases. In no case was there an additional attaching structure that did not meet criteria for the mt-MTLCL or the pf-ITB. The mt-MTLCL most commonly attaches to the Segond fragment, but the pf-ITB can also attach to this fragment. In no case was there an additional attaching structure that did not meet criteria for the mt-MTLCL or the pf-ITB. (orig.)

Although many studies indicate that people in low quality relationships are less healthy, precisely how relationships influence health remains unclear. We focus on one physiological pathway that may provide clues to understanding the link between relationships and health: the hypothalamic-pituitary-adrenal (HPA) axis. Evidence indicates that attachment processes in adult romantic relationships are associated with HPA responses to stress (assessed via cortisol levels). Specifically, attachment...

John Bowlby defined offspring-parent attachment as a relationship in which an infant or child uses one or a few preferred adults as a secure base from which to explore and as a haven of safety. He defined attachment security in terms of confidence in the adult’s availability and responsiveness and the smooth organization of exploration and proximity seeking. Developmental psychologists have found this perspective productive in both observational and laboratory research. At the same time, they...

This study aimed to experimentally track the tissue-scale strains of the tendon-bone attachment with and without a localized defect. We hypothesized that attachments with a localized defect would develop strain concentrations and would be weaker than intact attachments. Uniaxial tensile tests and digital image correlation were performed on rat infraspinatus tendon-to-bone attachments with defects (defect group) and without defects (intact group). Biomechanical properties were calculated, and tissue-scale strain distributions were quantified for superior and inferior fibrous and calcified regions. At the macroscale, the defect group exhibited reduced stiffness (31.3±3.7 N/mm), reduced ultimate load (24.7±3.8 N), and reduced area under the curve at ultimate stress (3.7±1.5 J/m2) compared to intact attachments (42.4±4.3 N/mm, 39.3±3.7 N, and 5.6±1.4 J/m2, respectively). Transverse strain increased with increasing axial load in the fibrous region of the defect group but did not change for the intact group. Shear strain of the superior fibrous region was significantly higher in the defect group compared to intact group near yield load. This work experimentally identified that attachments may resist failure by distributing strain across the interface and that strain concentrations develop near attachment defects. By establishing the tissue-scale deformation patterns of the attachment, we gained insight into the micromechanical behavior of this interfacial tissue and bolstered our understanding of the deformation mechanisms associated with its ability to resist failure.

The contribution of attachment to human development and clinical risk is well established for children and adults, yet there is relatively limited knowledge about attachment in adolescence due to the poor availability of construct valid measures. The Adult Attachment Projective Picture System (AAP) is a reliable and valid instrument to assess adult attachment status. This study examines for the first time the discriminant validity of the AAP in adolescents. In our sample of 79 teenagers between 15 and 18 years, 42 % were classified as secure, 34 % as insecure-dismissing, 13 % as insecure-preoccupied and 11 % as unresolved. The results demonstrated discriminant validity for using the AAP in that age group, with no associations between attachment classifications and verbal intelligence, social desirability, story length or sociodemographic variables. These results poise the AAP to be used in clinical intervention and large-scale research investigating normative and atypical developmental correlates and sequelae of attachment, including psychopathology in adolescence.

The primary aim was to determine the relative contributions of early attachment and abuse history to adult attachment, depression, and conflict resolution behaviors. Differences between abused and nonabused respondents were also assessed. A multi-scale questionnaire was completed by 879 college students. Hierarchical regression analyses were used to answer the primary research question, and analyses also compared the 26.4% of respondents who reported childhood abuse with those who did not. Respondents who indicated they had been abused as children reported less secure childhood and adult relationships than their nonabused counterparts. They were also more depressed and more likely to use destructive behaviors in conflict situations. Although both adult romantic attachment and respondents' depression scores were best accounted for by childhood attachment to mother and father rather than abuse history, the opposite pattern of results emerged for conflict resolution behaviors. In this case, abuse history was the stronger predictor, and parental attachment did not account for any significant additional variance. Results suggest that the long-term impact of childhood abuse may be mediated by early attachment experiences, whereas the long-term impact of abuse on conflict resolution behaviors may be considerably more direct.

Attachment theory has been proven essential for mental health, including psychopathology, development, and interpersonal relationships. Validated psychometric instruments to measure attachment abound but suffer from shortcomings common to traditional psychometrics. Recent developments in multimodal fusion and machine learning pave the way for new automated and objective psychometric instruments for adult attachment that combine psychophysiological, linguistic, and behavioral analyses in the assessment of the construct. The aim of this study was to present a new exposure-based, automatic, and objective adult-attachment assessment, the Biometric Attachment Test (BAT), which exposes participants to a short standardized set of visual and music stimuli, whereas their immediate reactions and verbal responses, captured by several computer sense modalities, are automatically analyzed for scoring and classification. We also aimed to empirically validate two of its assumptions: its capacity to measure attachment security and the viability of using themes as placeholders for rotating stimuli. A total of 59 French participants from the general population were assessed using the Adult Attachment Questionnaire (AAQ), the Adult Attachment Projective Picture System (AAP), and the Attachment Multiple Model Interview (AMMI) as ground truth for attachment security. They were then exposed to three different BAT stimuli sets, whereas their faces, voices, heart rate (HR), and electrodermal activity (EDA) were recorded. Psychophysiological features, such as skin-conductance response (SCR) and Bayevsky stress index; behavioral features, such as gaze and facial expressions; as well as linguistic and paralinguistic features, were automatically extracted. An exploratory analysis was conducted using correlation matrices to uncover the features that are most associated with attachment security. A confirmatory analysis was conducted by creating a single composite effects index and by testing it

Full Text Available This article presents a case of anterior diffuse scleritis that initially was diagnosed as conjunctivitis. Anterior diffuse scleritis (ADS is a potentially vision-threatening inflammation of the sclera whose etiology may include autoimmune and systemic conditions such as rheumatoid arthritis and tuberculosis. The signs and symptoms of ADS include pain, tearing, tenderness, redness, painful sensitivity to light and decreased visual acuity. Ocular and physical examinations including blood tests to rule out underlying causes are important. Medications such as corticosteroids, non-steroidal anti-inflam-matory drugs and possibly immune-suppressants are used in the management of ADS. If care is not taken, ADS can be mis-diagnosed as conjunctivitis because the redness is similar in both conditions. Such mis-diagnosis can be sight-threatening and therefore it is essential that primary eye care practitioners are cautious in all diagnoses of red eye conditions. (S Afr Optom 2012 71(1 51-54

In the acute setting, accurate radiological interpretation of paediatric cervical spine trauma can be difficult due to a combination of normal variants and presence of multiple synchondroses. We present a rare case of a fracture through the anterior atlantal synchondrosis in a paediatric spine. A five-year-old boy, who fell backwards onto the top of his head while swinging across on a monkey bar frame, presented with neck pain, cervical muscle spasm and decreased right lateral rotation and extension of his neck. Computed tomography showed a displaced diastatic fracture through right anterior atlantal synchondrosis. There are only 12 cases of paediatric C1 fractures reported in the world literature. The importance of considering this diagnosis in the appropriate clinical setting, and the normal variants in the paediatric atlas that can cause diagnostic dilemma to the interpreting radiologist, are discussed in this case report.

Full Text Available Total hip arthroplasty through minimum anterior incision is a minimally invasive technique that allows access to the joint capsule without posting the skeletal muscle surrounding areas. Anterior surgical approach is advantageous because the hip joint is located closer to the front than the rear part of the limb. The surgical approach follows a internervous plane between superior and inferior gluteal nerves (in the side and femoral nerve (medially, without involving the muscle removal. This technique provides good access, through the same incision, both to the acetabul and the femur. It also allows better control of the acetabular cup, keeping the limb length, a decrease of dislocations rate and reduced post-operative precautions.

A 39-year-old fisherman is reported who was dragged into the water from a boat after he became entangled in fishing line. His death was attributed to salt water drowning. At autopsy the cause of death was confirmed and the mechanism of the lethal event elucidated. Specifically, a large fish hook attached to line was embedded in his right wrist. The hook had passed beneath flexor tendons and had firmly attached him to fishing line that was being dropped from the vessel. There were no other significant injuries or underlying diseases present. This case demonstrates another rare situation in the commercial fishing industry that may result in a victim being dragged from a boat and drowned.

Today smartphones and tablets do not merely pervade our daily life, but also play a major role in STEM education in general, and in experimental investigations in particular. Enabling teachers and students to make use of these new techniques in physics lessons requires supplying capable and affordable applications. Our article presents the improvement of a low-cost technique turning smartphones into powerful magnifying glasses or microscopes. Adding only a 3D-printed clip attached to the smartphone's camera and inserting a small glass bead in this clip enables smartphones to take pictures with up to 780x magnification (see Fig. 1). In addition, the construction of the smartphone attachments helps to explain and examine the differences between magnifying glasses and microscopes, and shows that the widespread term "smartphone microscope" for this technique is inaccurate from a physics educational perspective.

Full Text Available Aim. To analyze the efficacy of modified pupillary massage technique using cycloplegic agent Appamide Plus in the treatment of anterior uveitis. Patients and methods. 45 patients (25 men and 20 women aged 21‑69 with endogenous uveitis (51 eyes were enrolled in the study. Etiology of uveitis was identified in 57.7 % of cases: herpes simplex virus (22.2 %; systemic disorders — rheumatoid arthritis, Reiter syndrome, Bechterew’s disease, psoriasis (17.7 %; local infection — purulent periodontitis or sinusitis (11 %. Patients were divided into two groups. Group I received basic therapy in combination with traditional pupillary massage. Group II received basic therapy in combination with modified pupillary massage using Appamide Plus (muscarinic receptor antagonist and alpha adrenergic agonist and plasma exchange with cell mass ozonation. Results. Inflammation of the uveal tract was prevented in all patients. In group I (traditional pupil massage, posterior synechiae persisted in 26 % of cases. In group II (pupil massage using Appamide Plus, anterior chamber humor was transparent, posterior synechiae were broken, normal pupillary response was re-established. Additionally, inflammatory exudate in the anterior chamber and endothelial precipitates resolved by 3.3 days earlier than in group I (р < 0.05. Visual outcomes were also better in Appamide Plus group. T cell-mediated immunity study revealed initial CD3+ cell and T cell subpopulation deficiency. Relative and absolute references of T cells and their subpopulations tended to decrease even when uveitis signs reduced. Conclusions. T cell-mediated immunity depression is probably due to pharmacotherapy. Appamide Plus eye drops are highly effective for therapeutic mydriasis and pupillary massage in the course of anterior uveitis treatment to prevent synechiae formation in enlarged or small pupil.

The anterior cruciate ligament (ACL) is an important structure in maintaining the normal biomechanics of the knee and is the most commonly injured knee ligament. However, the oblique course of the ACL within the intercondylar fossa limits the visualization and assessment of the pathology of the ligament. This pictorial essay provides a comprehensive and illustrative review of the anatomy and biomechanics as well as updated information on different modalities of radiological investigation of ACL, particularly magnetic resonance imaging.

Full Text Available ABSTRACT The shoulder is the most unstable joint in the human body. Traumatic anterior instability of the shoulder is a common condition, which, especially in young patients, is associated with high recurrence rates. The effectiveness of non-surgical treatments when compared to surgical ones is still controversial. The purpose of this study was to review the literature for current concepts and updates regarding the treatment of this condition.

The addition of insulation to the exterior of buildings is an effective means of increasing the thermal resistance of both wood framed walls as well as mass masonry wall assemblies. For thick layers of exterior insulation (levels greater than 1.5 inches), the use of wood furring strips attached through the insulation back to the structure has been used by many contractors and designers as a means to provide a convenient cladding attachment location (Straube and Smegal 2009, Pettit 2009, Joyce 2009, Ueno 2010). The research presented in this report is intended to help develop a better understanding of the system mechanics involved and the potential for environmental exposure induced movement between the furring strip and the framing. BSC sought to address the following research questions: 1. What are the relative roles of the mechanisms and the magnitudes of the force that influence the vertical displacement resistance of the system? 2. Can the capacity at a specified deflection be reliably calculated using mechanics based equations? 3. What are the impacts of environmental exposure on the vertical displacement of furring strips attached directly through insulation back to a wood structure?

Subjects for this research were 52 foster children (mean ages 7 years, 11 months) and their natural and foster parents. Case history files provided information concerning reasons for placing the children in foster care. Foster parents completed the Parent/Child Reunion Inventory (Marcus, 1988) measuring the "quality of reunion behavior" following separation. Foster mothers also completed the Child Behavior Checklist (Achenbach & Edelbrock, 1983), and measures of adult empathy were collected from both foster parents. Foster care workers rated the quality and intensity of attachment between the child and all parents. Finally, foster children were interviewed concerning their social supports, perception of affection from adults, and the quality of their relationships with adults and friends. Results showed that behavior and school achievement problems were predictable from measures of the quality of attachment with parents. The mean number of behavior problems of foster children were found to be midway between clinical and nonclinical norm groups. Children's perceptions of friends' behavior and degree of control over friends were related to their adjustment. Case history variables were also related to behavior problems and attachment.
Full Text Available Machiavellianism is a well-studied topic in several branches of psychology. Still, it has received little attention from a developmental perspective. Previous retrospective studies linked Machiavellianism to poor parental care, but actual reports of adolescents who live in their family of origin have been ignored so far. Therefore, we investigated the relationship between Machiavellianism and parental attachment in adolescence and possible sex differences based on life history theory. An adolescent sample (N = 376; 17.27 ± .77 years of age completed the Mach-IV and the maternal and paternal versions of revised Inventory of Parent and Peer Attachment (IPPA-R. According to our results, significant sex differences emerged in the relationship between Machiavellianism and attachment to parents. For girls, maternal alienation proved to be the only significant predictor of Machiavellianism, whereas for boys, low intensity and quality of verbal communication with father predicted higher levels of Machiavellianism. Results are discussed from an evolutionary perspective of socialization and from the perspective of emotion regulation.

To report a case of anterior sacral meningocele with intralesional bleeding secondary to sacrococcygeal trauma. Likewise, there is a discussion about the physiopathology and the surgical approach to these types of lesions. A 43-year-old man diagnosed with Marfan syndrome suffered sacrococcygeal trauma. He was admitted to the emergency room due to symptoms of headache, nausea, and lower limb subjective weakness. CT and MRI showed a large retroperitoneal mass with hemorrhagic content close to the sacrum. Likewise, the MRI showed an image compatible with subarachnoid hemorrhage in the thoracic spinal area, cerebral convexity, and the basal cisterns. The patient went into surgery for an anterior abdominal approach in the midline to reduce the content of the lesion, and subsequently, in the same act, a posterior approach was done with an S1-S2 laminectomy and obliteration of the pedicle. Postoperative MRI 5 months later showed resolution of the ASM. Anterior sacral meningocele is characterized by herniation of the dura mater and the arachnoid mater outside the spinal canal through a defect of the sacrum. We add the risk of bleeding after trauma-never seen in the literature-as one of the possible inherent complications of this lesion. This report highlights a complication never seen in the literature of a relatively rare condition. In our case, the combined approach was effective for both clinical control and lesion regression.

To describe the clinical and oculographic features in patients with anterior semicircular canal benign paroxysmal positional vertigo and to determine the efficacy of a canalith repositioning procedure for its management. Case series with chart review of patients presenting positional vertigo and positional downbeating nystagmus during a 2-year period. Outpatients' tertiary referral center for balance disorders. Eighteen patients suffering from positional vertigo and presenting positional downbeating nystagmus were treated with a maneuver based on a modification of the procedure proposed by Crevits. disappearance of positional downbeating nystagmus. Positional downbeating nystagmus was elicited unilaterally with the Dix-Hallpike maneuver in 6 cases. In 4 patients, it was triggered by both left and right Dix-Hallpike tests. In 8 patients, the positional nystagmus was elicited by a straight head-hanging maneuver. The positional nystagmus was purely downbeating in 12 patients. In the remaining, a torsional component was detected. After the treatment, only 1 patient showed positional nystagmus at 30 days. In anterior canal benign paroxysmal positional vertigo, the presence of a positional downbeating nystagmus in response to positional tests is key for diagnosis. In a significant number of patients, the affected side may not be detected because of the inconstant presence of a torsional component. Treatment with a simplified maneuver based on Crevits's technique can be considered an effective method for the treatment of anterior canal lithiasis, especially when the affected side cannot be detected clearly.
Full Text Available CONTEXT: A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specific, and anterior cruciate ligament ganglia are usually diagnosed through magnetic resonance imaging or arthroscopy. Not all ganglia diagnosed through magnetic resonance imaging need to undergo surgical treatment: only those that cause clinical signs and symptoms do. Surgical results are considered good or excellent in the vast majority of cases. CASE REPORT: A 29-year-old male presented with pain in the left knee during a marathon race. Physical examination revealed limitation in the maximum range of knee extension and pain in the posterior aspect of the left knee. Radiographs of the left knee were normal, but magnetic resonance imaging revealed a multi-lobed cystic structure adjacent to the anterior cruciate ligament, which resembled a ganglion cyst. The mass was removed through arthroscopy, and pathological examination revealed a synovial cyst. Patient recovery was excellent, and he resumed his usual training routine five months later.

To compare the refractive outcomes following penetrating keratoplasty and deep anterior lamellar keratoplasty in fellow eyes in patients with keratoconus. This is an observational retrospective review of consecutive patients with keratoconus first managed with penetrating keratoplasty in one eye and then with lamellar keratoplasty in the fellow eye, between 2002 and 2007. Data collection was based on patients' hospital records. Information related to assessment before surgery and at 1, 3, 6, 12, 24, and 48 months after keratoplasty were retrieved and considered in the analysis. Clinical evaluations included patients' medical histories and diagnosis of keratoconus, uncorrected and best corrected visual acuity, spherical equivalent, refractive cylinder, topographic cylinder, and high-order aberrations, complications, and adverse reactions. Data on contrast sensitivity, central corneal thickness, and central residual bed thickness (only for lamellar keratoplasty) were retrieved from anterior segment optical coherence tomography observation performed at 48 months. Sixteen patients (32 eyes), 7 males and 9 females, were included in the analyses. After 4 years from transplantation, at the end of follow-up, no statistically significant differences were found in visual acuity and refractive measures between the two keratoplasties. Perforating keratoplasty showed significant differences for contrast sensitivity at 6 cpd with maximum glare (p = 0.026) and without glare (p = 0.015). Deep anterior lamellar keratoplasty showed a negative correlation between central residual bed thickness and best corrected visual acuity (R = -0.414, p < 0.001). The manual pre-descemetic deep anterior lamellar keratoplasty used in this study showed refractive and visual results comparable to those obtained with penetrating keratoplasty. Such results indicated that leaving healthy stroma attached to Descemet's membrane does not compromise the clinical outcome in the short and long

Accurate tunnel placement is important for a successful anterior cruciate ligament (ACL) reconstruction. Controversy exists concerning the preferred method of femoral tunnel preparation, with proponents of both medial portal and transtibial drilling techniques. Current ACL literature suggests that placement of the femoral ACL attachment site posterior or "low" in the ACL footprint leads to more anatomically correct ACL mechanics and better rotational control. There is limited literature focusing on ACL graft displacement through knee range of motion based on specific paired placement of femoral and tibial tunnels. Our purpose was to assess ACL isometry between multiple combinations of femoral and tibial tunnels. We hypothesized that placement of the graft at the posterior aspect of the ACL footprint on the femur would be significantly less isometric and lead to more graft displacement as compared with central or anterior placement. The ACL of matched pairs of cadaveric knees was arthroscopically debrided while leaving the soft tissue footprint on the femur and tibia intact. One knee from each pair underwent notchplasty. In all knees, three femoral and three tibial tunnels were created at the anterior, central, and posterior aspects of the ACL footprint. A suture was passed through each tunnel combination (nine potential pairs), and the change in isometry was measured throughout full knee range of motion. Placement of the femoral tunnel along the posterior aspect of the ACL footprint was less isometric compared with a central or anterior position in the femoral footprint. Placement of a posterior tibial tunnel also led to decreased isometry, but tibial tunnel placement affected isometry to a lesser extent than femoral tunnel placement. The combination of a posterior femoral and posterior tibial tunnel resulted in greater than 1 cm of graft excursion from full flexion to extension. Placement of ACL tunnels at anisometric sites may adversely affect the mechanical
