Midpalatal suture of osteopetrotic (op/op) mice exhibits immature fusion. (1/206)

The midpalatal suture was observed histologically in both toothless osteopetrotic (op/op) and normal (control) mice. The normal mice had a mature sutural structure, which consists of a well-developed cartilage cell zone and palatal bone. In contrast, the thickness of the cartilage cell zone was substantially greater in the op/op mice than that in the controls. Moreover, the cartilage cells in the op/op mice were frequently found in the palatal bone as well as in the sutural space, exhibiting an imperfect fusion. It seems that immature fusion at the sutural interface in the op/op mice is related to a decrease in biting or masticatory force accompanied by the failure of tooth eruption in addition to an essential defect in osteoclast differentiation, which is a congenital symptom in op/op mice.  (+info)

Craniofacial sutures: morphology, growth, and in vivo masticatory strains. (2/206)

The growth and morphology of craniofacial sutures are thought to reflect their functional environment. However, little is known about in vivo sutural mechanics. The present study investigates the strains experienced by the internasal, nasofrontal, and anterior interfrontal sutures during masticatory activity in 4-6-month-old miniature swine (Sus scrofa). Measurements of the bony/fibrous arrangements and growth rates of these sutures were then examined in the context of their mechanical environment. Large tensile strains were measured in the interfrontal suture (1,036 microepsilon +/- 400 SD), whereas the posterior internasal suture was under moderate compression (-440 microepsilon +/- 238) and the nasofrontal suture experienced large compression (-1,583 microepsilon +/- 506). Sutural interdigitation was associated with compressive strain. The collagen fibers of the internasal and interfrontal sutures were clearly arranged to resist compression and tension, respectively, whereas those of the nasofrontal suture could not be readily characterized as either compression or tension resisting. The average linear rate of growth over a 1-week period at the nasofrontal suture (133.8 micrometer, +/- 50.9 S.D) was significantly greater than that of both the internasal and interfrontal sutures (39.2 micrometer +/- 11.4 and 65. 5 micrometer +/- 14.0, respectively). Histological observations suggest that the nasofrontal suture contains chondroid tissue, which may explain the unexpected combination of high compressive loading and rapid growth in this suture.  (+info)

Craniofacial skeletal abnormalities in anomalous calves with clefts of the face. (3/206)

Thirteen anomalous calves with clefts of the face were morphologically examined, and craniofacial skeletons were studied in detail. According to the type and site of the cleft, four groups could be distinguished: median cleft lip and jaw (CLJ); median cleft lip, jaw, and palate (CLJP); lateral CLJ; and cleft palate (CP), including unilateral and bilateral type. Craniofacial skeletal abnormalities were observed in several bones at the roof, wall, and floor of the nasal cavity and at the boundary portion between the nasal and cranial cavities. Fissure formation at the cranial sutures, partial absence of the nasal process of the incisive bone, and opening of the bony palate were characteristic changes in median CLJ and CLJP, lateral CLJ, and CP, respectively. Furthermore, various associated changes were recognized in the median and paramedian skeletal elements of the face and other organs. The morphological changes of craniofacial skeletons with various types of clefts of the face depended on the site and degree of the cleft formation and reflected developmental errors of the facial embryonic segments. These changes would suggest disorders of the correlated development of facial processes and of other fetal organs of the face. For these conditions, etiologically hereditary cases were negative.  (+info)

Expression patterns of Twist and Fgfr1, -2 and -3 in the developing mouse coronal suture suggest a key role for twist in suture initiation and biogenesis. (4/206)

Sutural growth depends on maintenance of a balance between proliferation of osteogenic stem cells and their differentiation to form new bone, so that the stem cell population is maintained until growth of the skull is complete. The identification of heterozygous mutations in FGFR1, -2 and -3 and TWIST as well as microdeletions of TWIST in human craniosynostosis syndromes has highlighted these genes as playing important roles in maintaining the suture as a growth centre. In contrast to Drosophila, a molecular relationship between human (or other vertebrate) TWIST and FGFR genes has not yet been established. TWIST mutations exert their effect via haploinsufficiency whereas FGFR mutations have a gain-of-function mechanism of action. To investigate the biological basis of FGFR signalling pathways in the developing calvarium we compared the expression patterns of Twist with those of Fgfr1, -2 and -3 in the fetal mouse coronal suture over the course of embryonic days 14-18, as the suture is initiated and matures. Our results show that: (1) Twist expression precedes that of Fgfr genes at the time of initiation of the coronal suture; (2) in contrast to Fgfr transcripts, which are localised within and around the developing bone domains, Twist is expressed by the midsutural mesenchyme cells. Twist expression domains show some overlap with those of Fgfr2, which is expressed in the most immature (proliferating) osteogenic tissue.  (+info)

Location of the glenoid fossa after a period of unilateral masticatory function in young rabbits. (5/206)

Changes in glenoid fossa position and skull morphology after a period of unilateral masticatory function were studied. The right-side maxillary and mandibular molars in twenty-seven 10-day-old rabbits were ground down under general anaesthesia. The procedure was repeated twice a week, until the rabbits were 50 days old. Fourteen rabbits were then killed and 13 left to grow to age 100 days. Nine 50-day-old and sixteen 100-day-old rabbits with unmodified occlusions served as controls. Three-dimensional measurements were made using a machine-vision technique and a video-imaging camera. The glenoid fossa position become more anterior in both groups of animals subjected to molar grinding as compared with controls (P < 0.01 in the 50-day-old group and P < 0.05 in 100-day-old group). In the 100-day-old group the right-side fossa was also in a more inferior position (P < 0.01). The glenoid fossa was more anteriorly located on the right than on the left side of individual animals in the group in which the right-side molars had been ground down (P < 0.001).  (+info)

Strain in the braincase and its sutures during function. (6/206)

The skull is distinguished from other parts of the skeleton by its composite construction. The sutures between bony elements provide for interstitial growth of the cranium, but at the same time they alter the transmission of stress and strain through the skull. Strain gages were bonded to the frontal and parietal bones of miniature pigs and across the interfrontal, interparietal and coronal sutures. Strains were recorded 1) during natural mastication in conjunction with electromyographic activity from the jaw muscles and 2) during stimulation of various cranial muscles in anesthetized animals. Vault sutures exhibited vastly higher strains than did the adjoining bones. Further, bone strain primarily reflected torsion of the braincase set up by asymmetrical muscle contraction; the tensile axis alternated between +45 degrees and -45 degrees depending on which diagonal masseter/temporalis pair was most active. However, suture strains were not related to overall torsion but instead were responses to local muscle actions. Only the coronal suture showed significant strain (tension) during jaw opening; this was caused by the contraction of neck muscles. All sutures showed strain during jaw closing, but polarity depended on the pattern of muscle usage. For example, masseter contraction tensed the coronal suture and the anterior part of the interfrontal suture, whereas the temporalis caused compression in these locations. Peak tensile strains were larger than peak compressive strains. Histology suggested that the skull is bent at the sutures, with the ectocranial surface tensed and the endocranial surface predominantly compressed. Collectively, these results indicate that skulls with patent sutures should be analyzed as complexes of independent parts rather than solid structures.  (+info)

Trigonocephaly in rabbits with familial interfrontal suture synostosis: the multiple effects of premature single-suture fusion. (7/206)

Previous studies from our laboratory have characterized the craniofacial morphology and growth patterns of an inbred strain of rabbits with autosomal dominant coronal suture synostosis. A number of rabbit perinates from this colony have been collected sporadically over a 5-year period with premature interfrontal suture synostosis. The present study describes the very early onset of craniofacial dysmorphology of these rabbits and compares them to similar-aged normal control rabbits. A total of 40 perinatal New Zealand White rabbits were used in the present study. Twenty-one comprised the sample with interfrontal suture synostosis and ranged in age from 27 to 38 days postconception (term = 31 days) with a mean age of 33.53 days (+/-2.84 days). Nineteen rabbits served as age-matched, normal controls (mean age = 33.05 days +/-2.79 days). Lateral and dorsoventral radiographs were collected from each rabbit. The radiographs were traced, computer digitized, and 12 craniofacial measurements, angles, and indices were obtained. Mean measures were compared using an unpaired Student's t-test. All synostosed rabbits were stillborn or died shortly after birth. Grossly, these rabbits exhibited extreme frontal bossing, trigonocephaly with sagittal keeling, and midfacial shortening. No somatic anomalies were noted. Radiographically, rabbits with interfrontal suture synostosis had significantly (P < 0.05) narrower bifrontal widths, shorter cranial vault lengths, kyphotic cranial base angles, and different cranial vault indices (shapes) compared to controls. Results reveal severe and early pathological and compensatory cranial vault changes associated with premature interfrontal suture synostosis in this rabbit model. The 100% mortality rate noted in this condition may be related to the inheritance of a lethal genetic mutation or to neural compression from reduced intracranial volume. Results are discussed in light of current pathogenic hypotheses for human infants with premature metopic suture synostosis.  (+info)

Compressive force promotes chondrogenic differentiation and hypertrophy in midpalatal suture cartilage in growing rats. (8/206)

Midpalatal suture cartilage (MSC) is secondary cartilage located between the bilateral maxillary bones and has been utilized in the analysis of the biomechanical characteristics of secondary cartilage. The present study was designed to investigate the effects of compressive force on the differentiation of cartilage in midpalatal suture cartilage in rats. Forces of various magnitudes were applied to the midpalatal suture cartilage in 4-week-old male Wistar rats for 1, 2, 4, 7, or 14 days, mediated through the bilateral 1st molars using orthodontic wires. The differentiation pathways in the MSC cells were examined by immunohistochemistry for the differentiation markers type I, type II and type X collagen, and glycosaminoglycans (GAGs), chondroitin-4-sulfate, chondroitin-6-sulfate and keratan sulfate. Histologically and immunohistochemically, the midpalatal suture cartilage in control rats had the characteristic appearance of secondary cartilage. In the experimental groups, the center of the midpalatal suture cartilage that contained osteo-chondro progenitor cells seemed to become mature cartilage and its immuno-reaction to type II and X collagen and GAGs increased as the experiment progressed. This differentiation was dependent upon the magnitude and duration of the force applied to the midpalatal suture cartilage; i.e., cartilaginous differentiation progressed more rapidly as the applied force increased. The present results suggest that the differentiation of osteo-chondro progenitor cells into mature and hypertrophic chondrocytes in the precartilaginous cell layer is promoted by compressive force.  (+info)

Metopism is the condition of having a persistent metopic suture, or persistence of the frontal metopic suture in the adult human skull. The premature fusion of cranial sutures named craniosynostosis, it is "simple" when only one cranial suture is involved and "compound" when two or more cranial sutures are involved. Metopism is the opposite of craniosynostosis. The main factor of the metopic suture is to increase the volume of the anterior cranial fossa. The frontal bone includes the forehead, and the roofs of the orbits (bony sockets) of the eyes. The frontal bone has vertical portion (squama) and horizontal portion (orbital part). Some adults have a metopic or frontal suture in the vertical portion. In uterine period in right and left half of frontal region of the fetus there is a membrane tissue. On each half a primary ossification center appears about the end of the second month of the fetus. Primary ossification center extends to form the corresponding half of the vertical part (squama) and ...
CRANIOSYNOSTOSIS. Craniosynostosis is a birth defect of the Skull (which may affect the Brain) that is characterized by the premature closure of one or more of the fibrous joints between the bones of the Skull (called the cranial sutures) before Brain growth is complete. While the premature fusion of the cranial sutures results in disproportionate growth of the cranial bones, it may also affect the growth of the facial bones. When a suture is fused there is no growth in a plain perpendicular to the line of the suture. The abnormally shaped Skull that results is due to the Brain not being able to grow in its natural shape because of the closure. Instead it compensates with growth in areas of the Skull where the cranial sutures have not yet closed.. The Skull has two different components, the first of which forms the "vault" of the Cranium and is called the "membranous" part. The other portion, the "chondrocranium" forms the Base of the Skull. After a certain age there is little likelihood of ...

During craniofacial development, the Hedgehog (HH) signaling pathway is essential for mesodermal tissue patterning and differentiation. The Hedgehog family consists of three protein ligands: Sonic Hedgehog (SHH), Indian Hedgehog (IHH), and Desert Hedgehog (DHH), of which two are expressed in the craniofacial complex (IHH and SHH). Dysregulations in HH signaling are well documented to result in a wide range of craniofacial abnormalities, including holoprosencephaly, hypotelorism, and cleft lip/palate. Furthermore, mutations in HH effectors, co-receptors, and ciliary proteins result in skeletal and craniofacial deformities. Cranial suture morphogenesis is a delicate developmental process that requires control of cell commitment, proliferation and differentiation. This review focuses on both what is known and what remains unknown regarding HH signaling in cranial suture morphogenesis and intramembranous ossification. As demonstrated from murine studies, expression of both SHH and IHH is critical to the
The joints between the craniofacial bones (sutures) are vital for proper brain and craniofacial development and have recently been identified as a niche for stem cells. The Centers for Disease Control and Prevention, National Birth Defects Study has published data suggesting that "environmental" exposures including maternal thyroid diseases, maternal nicotine use, and use of selective serotonin reuptake inhibitors (SSRIs) in pregnant mothers may exacerbate incidence and or severity of craniofacial anomalies including craniosynostosis. Craniosynostosis is a birth defect defined as the premature fusion of the suture(s) of the skull occurring in 1:1800-2500 births. A proposed mechanism of craniosynostosis is the disruption of the balance of proliferation and differentiation of cells in the perisutural area leading to bone overgrowth. The newly identified stem cell population characterized as Gli1+ may be the target of pharmacological exposures that result in aberrant craniofacial growth. For these ...

Squama (squama frontalis).-Surfaces.-The external surface (Fig. 134) of this portion is convex and usually exhibits, in the lower part of the middle line, the remains of the frontal or metopic suture; in infancy this suture divides the bone into two, a condition which may persist throughout life. On either side of this suture, about 3 cm. above the supraorbital margin, is a rounded elevation, the frontal eminence (tuber frontale). These eminences vary in size in different individuals, are occasionally unsymmetrical, and are especially prominent in young skulls; the surface of the bone above them is smooth, and covered by the galea aponeurotica. Below the frontal eminences, and separated from them by a shallow groove, are two arched elevations, the superciliary arches; these are prominent medially, and are joined to one another by a smooth elevation named the glabella. They are larger in the male than in the female, and their degree of prominence depends to some extent on the size of the frontal ...

Craniosynostosis is a congenital malformation characterized by premature closure of cranial sutures. The premature closure of the cranial sutures hinders the growth of the skull, brains and face. Craniosynostosis is 1 in 2500 newborns and is for approximately 40% of patients a part of a syndrome such as Apert syndrome, Crouzon / Pfeiffer, Saethre-Chotzen and Muenke. The treatment of syndromic or complex craniosynostosis craniofacial comprises a correction within the first year of life. Depending on the syndrome, multiple corrections of the skull, face hands and feet occur. Besides the appearance, the skull abnormality, hand and foot abnormalities, and brain abnormalities may occur. These brain abnormalities can be congenital, such as abnormalities of the corpus callosum or acquired, such as hydrocephalus ...
Osteoclasts demonstrate ontogenetic changes in site specificity. Figure 3 and Table 1 clearly show that TRAP-positive osteoclasts are absent during initial postnatal development. This does not preclude the presence of osteoclasts at this time. In fact, Rice et al. (1997) have shown MMP-9-positive osteoclasts at these ages. The probable reason for this is because the calvarial bone being deposited at these newborn stages is low in mineral content. The matrix metalloproteinase, MMP-9, is thought to be sufficient for the early requirements of bone resorption. Later in postnatal development as bone becomes more densely mineralized, TRAP-positive osteoclasts would be required for resorption. Congruent with this explanation, osteoclasts are observed along concave and straight sagittal suture margins at 10 days postnatal. By 21 days postnatal, one can observe osteoclasts along convex margins as well. The occurrence of osteoclasts along convex and concave regions increases incrementally until 42 days ...
Todays sutures are the result of a 4000-year innovation process with regard to their materials and manufacturing techniques, yet little has been done to enhance the therapeutic value of the suture itself. In this review, we explore the historical development, regulatory database and clinical literature of sutures to gain a fuller picture of suture advances to date. First, we examine historical shifts in suture manufacturing companies and review suture regulatory databases to understand the forces driving suture development. Second, we gather the existing clinical evidence of suture efficacy from reviewing the clinical literature and the Food and Drug Administration database in order to identify to what extent sutures have been clinically evaluated and the key clinical areas that would benefit from improved suture materials. Finally, we apply tissue engineering and regenerative medicine design hypotheses to suture materials to identify routes by which bioactive sutures can be designed and passed through

In the paediatric age group, IIH has specific characteristics that differ from those in adults. It could be further divided into 2 age groups with different clinical manifestations and outcomes: children with open cranial sutures and fontanelles, and older children with closed fontanelles.. In infants with open sutures, the most frequent reason for seeking care is a bulging fontanelle, usually detected by the parents, in isolation or possibly associated with irritability. Males predominate in this age band, and triggering factors are often identified, most frequently steroid therapy for bronchitis or upper respiratory tract infections. The outcome is usually good, with IIH resolving spontaneously and without complications in a few days (based in our experience, approximately 1 week), and papilloedema is a rare finding due to the distensibility of the cranial sutures. Given its benign course and outcomes, it is possible to consider close monitoring without additional testing in infants with ...
Craniosynostosis is caused by premature closure of the cranial sutures and an associated growth arrest perpendicular to the involved suture line, resulting in a skull deformity that progresses over time until growth is completed. It is therefore important that this issue be surgically addressed early in infancy. It may be part of the previously noted syndromic paradigm, which is associated with brachydactyly (foreshortened extremities), syndactyly (fusion of the phalanges and obliteration of the natural web spaces), and polydactyly (extra digits). There is a great deal of overlap of phenotypic expression among these subtypes. Craniosynostosis may be caused by a new mutation or display either an autosomal dominant or recessive genetic pattern of inheritance. There is evidence of defects in fibroblast growth factor regions (FGFR) of the genome, resulting in abnormal bridging ossification of mesenchymal tissue. ...
TY - JOUR. T1 - Extrinsic tension results in FGF-2 release, membrane permeability change, and intracellular Ca++ increase in immature cranial sutures. AU - Yu, Jack C.. AU - Lucas, Jay H.. AU - Fryberg, Karsten. AU - Borke, James L.. PY - 2001/1/1. Y1 - 2001/1/1. N2 - There are numerous studies cataloging the temporal profiles of the various growth factors during the morphogenesis of cranial sutures. There are also many clearly documented mutations of the receptors of some of these growth factors such as fibroblast growth factor (FGF)R-2 and FGFR-3 in clinical craniosynostosis. It is obvious, and often concluded, that growth factors play a role or are involved in craniofacial development. However, precisely what that role is, what causes the changes in the growth factor levels, and why these changes occur in the particular temporal and spatial patterns observed remains elusive. Using simple physics, we applied a plasma membrane disruption model and the principles of complex adaptive systems to ...
General Discussion. The human skull is a complex part of the body. It is key in identification of sex by the size of the Mastoid Process, Supraorbital Torus, tooth size, and the squareness of the mandible amongst others; it can also be used in describing age at death by tooth wear, Cranial Suture closure and general porosity of the bone (Roberts & Manchester 2010, White & Folkens 2005, Jurmain et al 2011). A later post will detail exactly how in further detail.. It has also changed as our species, Homo Sapiens, evolved from earlier hominids. The morphology of the human skull has certainly become more gracile, and as an indicator and outcome of the agricultural revolution, it seems our mandibular size and muscle robusticity has slowly become less pronounced (Larsen 1999: 230, Jurmain et al 2011). As Larsen remarks (1999: 226), it is the influence of environment and mechanical behaviour that helps determine the morphology of the skull, alongside considered genetic factors. It is important we keep ...
A form of craniosynostosis, a primary abnormality of skull growth involving premature fusion of one or more cranial sutures. The growth velocity of the skull often cannot match that of the developing brain resulting in an abnormal head shape and, in some cases, increased intracranial pressure, which must be treated promptly to avoid permanent neurodevelopmental disability ...
UniProtKB/Swiss-Prot : 71 Muenke syndrome: A condition characterized by premature closure of coronal suture of skull during development (coronal craniosynostosis), which affects the shape of the head and face. It may be uni- or bilateral. When bilateral, it is characterized by a skull with a small antero- posterior diameter (brachycephaly), often with a decrease in the depth of the orbits and hypoplasia of the maxillae. Unilateral closure of the coronal sutures leads to flattening of the orbit on the involved side (plagiocephaly). The intellect is normal. In addition to coronal craniosynostosis some affected individuals show skeletal abnormalities of hands and feet, sensorineural hearing loss, mental retardation and respiratory insufficiency ...

The parietal bone articulates with five bones: the frontal, the opposite parietal, the occipital, the temporal, and the sphenoid. Its anterior border, forming the coronal or frontoparietal suture, is denticulate laterally and becomes more serrate medially. The interparietal or sagittal suture formed at the junction of the medial borders of the two parietal bones is deeply denticulate. The sagittal suture becomes more butt-like, sometimes fusing, toward the internal surface while it remains denticulate toward the external surface. This reflects the mechanical design to resist the greater compressional forces near the internal surface and the corresponding tensile forces near the external surface. The posterior border, also deeply denticulate, forms the lambdoidal or parieto-occipital suture. The lateral border forms a small denticulate suture with the mastoid region of the temporal bone. The remaining greater portion of the lateral border forms the squamous suture with the squamous temporal bone ...

A package for double-armed sutures, particularly ophthalmic sutures, comprising a one-piece folded packet having needle mounting means and suture loop retaining means which are readily accessible when the package is opened. The needle mounting means is preferably removable to allow the suture to be withdrawn from the package with the needles secured therein. The suture loop retaining means is optionally incorporated with the needle mounting means and removable therewith. The package contains a single, double-armed suture with both needles secured in the needle mounting means and with a loop substantially equidistant from each needle retained in the suture loop retaining means so that the suture may be cut at the loop to obtain two single-armed sutures of substantially equal length.
... We have now enumerated three sutures that more frequently occur in the naturally shaped head. When a skull is lying on its side, these describe the letter H, or rather h. 65 In the heads that vary from the natural structure, the sutures are as follows. 66 Where the anterior eminence of the head is missing (Chapter 5, figure 2), the coronal suture is absent and the lambdoid remains together with the sagittal, which then runs to the middle of the brows [sutura metopica]. Where the posterior eminence is missing (Chapter 5, figure 3), the lambdoid suture is lost and the coronal remains, while the sagittal is extended through the middle of the occiput to the base of the skull. If you imagine this one resting on its occiput, each of the remaining sutures will resemble the letter T; similarly, the sutures of the first unnatural type will resemble a T 67 when it is rested on its forehead. When the anterior and posterior eminences are both missing (Chapter 5, figure 4), the two ...

mama e 10, 1950 SUTURES Herbert L. Davis, Highlflul N. 1., and Park, Matthew L. Tringali, Brooklyn, N. Y., assignors to Johnson & Johnson, a corporation of New Jersey No Drawing. Application December 15, 1944, Serial No. 568,400 Claims. (Cl. 128-3355) This invention relates to surgical suturm, and particularly to the composition of the liquid in which sutures are usually packed and stored. It results from our discovery that sutum formed of absorbable protein such as animal tissue when stored in solutions of critical proportions of the propyl alcohols have unexpected properties and marked advantages over sutures heretofore known. In order to provide surgeons with sutures which are both sterile and soft and therefore ready to use, it has been the practice to pack the suture in a glass tube containin a preserving or conditioning liquid, called tubing fluid, the tube being sealed hermetically either before or after sterilizing the suture, depending on the nature of the suture and the particular ...

Craniosynostosis (from cranio, cranium; + syn, together; + ostosis relating to bone) is a condition in which one or more of the fibrous sutures in an infant (very young) skull prematurely fuses by turning into bone (ossification), thereby changing the growth pattern of the skull. Because the skull cannot expand perpendicular to the fused suture, it compensates by growing more in the direction parallel to the closed sutures. Sometimes the resulting growth pattern provides the necessary space for the growing brain, but results in an abnormal head shape and abnormal facial features. In cases in which the compensation does not effectively provide enough space for the growing brain, craniosynostosis results in increased intracranial pressure leading possibly to visual impairment, sleeping impairment, eating difficulties, or an impairment of mental development combined with a significant reduction in IQ. Craniosynostosis occurs in one in 2000 births. Craniosynostosis is part of a syndrome in 15 to 40% ...
The skull is made up of many bones, 8 in the skull itself and 14 in the face area. They join together to form a solid, bony cavity that protects and supports the brain. The areas where the bones join together are called the sutures.. The bones are not joined together firmly at birth. This allows the head to change shape to help it pass through the birth canal. The sutures get minerals added to them over time and harden, firmly joining the skull bones together.. In an infant, the space where two sutures join forms a membrane-covered "soft spot" called a fontanelle (fontanel). The fontanelles allow for growth of the brain and skull during an infants first year.. There are normally several fontanelles on a newborns skull. They are located mainly at the top, back, and sides of the head. Like the sutures, fontanelles harden over time and become closed, solid bony areas.. ...
The control of motor function, to which much of the human nervous system is committed, is accomplished through the integrated action of a vast array of segmental and suprasegmental motor neurons. As originally conceived by Hughlings Jackson in 1858, purely on the basis of clinical observations, the motor system is organized hierarchically in three levels, each higher level controlling the one below. It was Jacksons concept that the spinal and brainstem neurons represent the lowest, simplest, and most highly organized motor centers; that the motor neurons of the posterior frontal region represent a more complex and less closely organized second motor center; and that the prefrontal parts of the cerebrum are the third and highest motor center. This scheme is still regarded as being essentially correct, although Jackson failed to recognize the importance of the parietal lobe and basal ganglia in motor control. ...
The common heart diseases resulting in a brain abscess are associated with a right to left shunt and include tetralogy of Fallot and transposition of great vessels. Atrial septal defect (ASD) is almost always associated with the left to right shunt and therefore is not a commonly considered risk factor for brain abscess. We report the case of a 29-year-old male, with no symptoms of cardiac disease, who presented with the left posterior frontal pyogenic abscess which led to the detection of a silent ASD. Our case emphasizes the need for a careful evaluation of the source of infection in patients with a brain abscess ...

Headaches can be one of the most debilitating conditions anyone can have. Headache pain can stem from migraines, which are typically more vascular in nature, to sinus inflammation, to residual pain from trauma associated with concussion, whiplash, or traumatic brain injury. Dr. Jess has first hand experience with post-concussion syndrome due to TBI. After living in extreme pain for over a decade, Dr. Ritegno was just recently able to find one form of treatment that seemed to hold her symptoms at bay. After learning of Nasal Specific, Dr. Ritegno became a trained provider in order to provide relief and comfort to patients with similar pain! This technique involves inflating a small balloon up through each of the nasal sinus cavities in order to manipulate the cranial suture joints. When we breathe, these joints should also expand and contract. After trauma or inflammation to the area, these joints can become jammed, which in turn can cause or worsen headache pain. If you have not found any relief ...

A pump for pumping drugs, medicaments or other liquids is disclosed in one embodiment having suture loops co-extensive with the outside surface of the pump. At least one depression is formed in the outside surface of the pump. A wire co-extensive with the outer dimensions of the pump passes over the depression forming a space between the wire and the outside surface of the pump in the depression. In this position, the wire forms a suture loop. The surgeon, when suturing the pump of the present invention in place within a pocket of tissue or other similar location, places a suture between the wire and the outside surface of the pump in the depression to secure the pump. In another embodiment, depressions are created in a pump and a soft material is placed in and attached to the depressions. A suture may then be placed through the material of the soft material and the tissue of the patient in a pocket in the tissue of the patient to affixed the pump in the pocket.

A babys head, or skull, is made up of many different bones. The connections between these bones are called sutures. When a baby is born, it is normal for these sutures to be open a little. This gives the babys brain room to grow.. Craniosynostosis is a condition that causes one or more of the babys sutures to close too early. This can cause the shape of your babys head to be different than normal.. An x-ray or computed tomography (CT) scan can be used to diagnose craniosynostosis. Surgery is usually needed to correct it.. Surgery frees the sutures that are fused. It also reshapes the brow, eye sockets, and skull as needed. The goals of surgery are:. ...

School of Architecture, Room N107.. In a 1919 essay entitled "Primal Sound," Rainer Maria Rilke fantastically imagines using the phonograph stylus to "play" the coronal suture of the skull, thereby liberating a previously unknown range of sound, music, and emotion. "Primal Sound" describes a posthuman positionality whereby one might use the prosthetic extension of technical media to engage in a radical self-examination-an "auto-autopsy" that bypasses the evaluative apparatus of the rationalist subject and directly accesses the previously buried acoustic life of the human. While Rilke regards his experiment as an occult preoccupation, this talk traces remarkably similar associations between technical media and the skulls coronal suture across a range of modernist authors and artists. In texts by Mina Loy, the Baroness Elsa von Freytag-Loringhoven, and Man Ray, sutures and grooves define new interfaces between the body and technical media, as the skull is reimagined as a site of technological ...
The external surface [Fig. 1] of this portion is convex and usually exhibits, in the lower part of the middle line, the remains of the frontal or metopic suture; in infancy this suture divides the bone into two, a condition which may persist throughout life. On either side of this suture, about 3 cm. above the supraorbital margin, is a rounded elevation, the frontal eminence (tuber frontale). These eminences vary in size in different individuals, are occasionally unsymmetrical, and are especially prominent in young skulls; the surface of the bone above them is smooth, and covered by the galea aponeurotica. Below the frontal eminences, and separated from them by a shallow groove, are two arched elevations, the superciliary arches; these are prominent medially, and are joined to one another by a smooth elevation named the glabella. They are larger in the male than in the female, and their degree of prominence depends to some extent on the size of the frontal air sinuses; 28 prominent ridges are, ...

Dental eruption and oral health are unique areas of research within the swine industry and are likely to provide novel insights into the growth, health, and development of individuals. Although body weight is the preferred measure for growth, one may argue that teeth provide a more stable marker because their development is more resistant to nutritional disruptions as compared to other tissues (ie, fat, muscle, bone).15,16 Dental eruption provides an interesting area of investigation, particularly when examining the potential growth of an individual early in its development. Possible mechanisms underlying the relationship between growth and dental eruption include enhanced feeding efficiency, improved digestion after a more thorough mechanical breakdown of food, and underlying genetic linkages. Our lack of knowledge in all three of these areas suggests more research should be carried out on the fundamental development of teeth in pigs and their synergistic role in food intake, mastication, and ...

The gauze recommended for this kit is the Kling type. This gauze adheres to itself, thereby making it easier to use. A gaping wound should be brought together with a "butterfly" plastic tape. In areas where there is a fair amount of movement, a butterfly may not do the job. A suture may be needed. No one should attempt sutures … even if he knows how if the victim can be taken to a doctor. But if a doctor is days away, there may be no other choice. Making a stitch or suture is not difficult. Since the wound is generally painful already and the nerves lying close to the skin are frequently severed by the cut, the needle causes less pain than one might suspect. No pain killers such as Novocain are used, because syringes and needles require special precautions that just dont fit into the scheme of a first-aid kit such as this ...

Non-dissolvable sutures are made of materials which are not metabolized by the body and are therefore either permanently implanted in the body or removed after the wound is healed.
Patients often ask when they can swim after a wound has been sutured. Despite such an apparently simple query, evidence supporting any answer seems to be lacking. Many patient information sites advise against swimming after the suturing of wounds1 but fail to provide evidence to support this recommendation. Advice is broad ranging and inconsistent.1 Current information ranges from waiting until the sutures are removed and the wound has healed1 to abstaining from swimming for six weeks postoperatively.2 Patients with external frame fixators are advised that it is permissible to swim in a chlorinated pool or clean sea water, although in practice this is difficult to ascertain and is far from an objective measure, once the pin sites have healed.3 Evidence to back up the advice is scarce.. Concerns about the risks of swimming with a sutured wound primarily centre on the potential for infection,4 5 as opposed to impaired wound healing. The risk of infection depends on the type of wound (for example, ...

Alex Shoebridge discovered her unborn son Saul had the rare condition craniosynostosis at a 32-week scan. At nine months old he underwent a lifesaving operation at the Royal Hospital for Sick Children in Glasgow.
Craniosynostosis is a birth defect in which the bones of the skull prematurely fuse. This causes skull to develop an abnormal shape and can cause cognitive issues if severe enough. Interventions include either endoscopic or open surgery. Why would you choose one over the other?
The craniosynostosis program at Stanford Childrens Health provides comprehensive diagnostic evaluation and treatment of children with skull abnormalities.
