Melanotic neuroectodermal tumor of infancy (MNTI) is exceptionally rare and occurs predominantly in the head and neck (92.8 % cases). The patient reported here is only the eighth case of MNTI presenting in an extremity, and the first reported in the fibula.A 2-month-old female presented with a mass arising in the fibula. Exhaustive genomic, transcriptomic, epigenetic and pathological characterization was performed on the excised primary tumor and a derived cell line. Whole-exome analysis of genomic DNA from both the tumor and blood indicated no somatic, non-synonymous coding mutations within the tumor, but a heterozygous, unique germline, loss of function mutation in CDKN2A (p16(INK4A), D74A). SNP-array CGH on DNA samples revealed the tumor to be euploid, with no detectable gene copy number variants. Multiple chromosomal translocations were identified by RNA-Seq, and fusion genes included RPLP1-C19MC, potentially deregulating the C19MC cluster, an imprinted locus containing microRNA genes reactivated by

Context: Care of a child having colostomy has not been institutionalized for a long time for economic and administrative reasons. After stoma formation, stoma care has to be provided to the child by caregivers at home. Hence, caregivers need to be provided with ongoing education and support, commencing from preoperative teaching to discharge from the hospital and home care. Aims: The aims of this study were to develop video-based learning resource material and to evaluate its effectiveness in terms of knowledge and skill attainment by caregivers. Settings and Design: The study design was time series, one group pretest and post test. This was conducted among 30 caregivers attending pediatric surgery outpatients and indoor departments of a tertiary level care center. Materials and Methods: A video teaching program (VTP) related to pediatric colostomy was developed and used to teach the caregivers about colostomy care. Pretested and validated knowledge questionnaire, observational checklist, and ...

The baby was admitted to the NICU postoperatively and intubated for approximately 12 hours. The condition was stable on discharge, and follow-up thus far has been unremarkable.. Definitive histological examination later confirmed excision of the entire tumour, the features of which were unchanged from the initial report.. Discussion. The list of possible causes for nasal obstruction in the neonatal period is a long one, the most common being nasal mucosal oedema, infectious causes such as syphilis (rare nowadays), bony abnormalities such as pyriform aperture stenosis, choanal atresia, cystic lesions such as a dacrocystocele or Rathkes pouch cyst, Thornwaldt cyst, and other developmental midline nasal lesions such as a meningo-encephalocele or glioma. Neoplastic lesions are usually benign, and include dermoids, hamartomas, teratomas and haemangiomas. Malignant lesions such as neuroblastoma, rhabdomyosarcoma or lymphoma may be seen, but are extremely rare, and metastatic disease even more so. ...

The pathologic and immunohistochemistry features of the SGAT, as described by Dehner et al,1 were constant between cases in that report and similar to the case presented here. The histology of the SGAT suggests that of a normally developing salivary gland, with invaginating surface epithelium into mesenchymal tissue, suggesting that SGAT may be a hamartoma, rather than a neoplasm.1. Symptoms of nasal obstruction from SGAT are similar to nasal obstruction from other causes, and may include sleeping difficulty, feeding problems, episodes of respiratory distress and/or cyanosis, and nasal discharge. Neonates with complete nasal obstruction may have severe respiratory distress which is relieved by crying7; however, neonates with even partial nasal obstruction may be symptomatic.8 Retractions, stridor, a weak or breathy cry, or respiratory distress not relieved or worse with crying may indicate laryngotracheal abnormalities.. The cause of neonatal nasal obstruction may sometimes be revealed by ...

Karyotyping analyzes revealed that the chromosome numbers of the three cell systems ranged from 60 to 67 with 3n ploidies, and that there were many structural aberrations, such as del(11)(q13), del(22)(q13), add(2)(p11), add(7)(q22), extra copies for chromosomes 1, 2, 3, 5, 7, 9, 10, 11, 12, 16, 20, and 22, der(9)t(9;13)(p13;q12)add(9)(q34), and der(13;21)(q10;q10), which were shared by the three cell systems, while der(19)t(11;19)(q13;p13) was found in MINT1 and MINT3 ...

Neurocutaneous melanosis is a congenital disorder characterized by the presence of congenital melanocytic nevi on the skin and melanocytic tumors in the leptomeninges of the central nervous system. These lesions may occur in the amygdala, cerebellum, cerebrum, pons, and spinal cord of patients. Although typically asymptomatic, malignancy occurs in the form of leptomeningeal melanoma in over half of patients. Regardless of the presence of malignancy, patients with symptomatic neurocutaneous melanosis generally have a poor prognosis with few treatment options. The pathogenesis of neurocutaneous melanosis is believed to be related to the abnormal postzygotic development of melanoblasts and mutations of the NRAS gene. Neurocutaneous melanosis was first described in 1861 by Rokitansky. It was first named by Van Bongaert in 1948. Premortem detection is difficult without the use of MRI. This, combined with the asymptomatic nature of most cases, led to the early belief that all cases were fatal. ...

In the rat fetuses the anlage of the milk duct was first observed about the seventeenth or eighteenth day. At this time the deep part of each epithelial mammary gland anlage apparently elongates or sends out a single bud-like process which is the primary duct anlage. This stage may be said to correspond to Reins (82) period of bud formation (Kjiospenbildung) in rabbits. It differs, however, from the findings of Langer (51), Huss (71), Kolliker (79), Rein (82), Profe (98), Hamburger (00), Brouha (05), Lustig (16), and many others in that they observed a variable number of buds (primary duct anlages) in man and other animal species including the horse, pig, cat and rabbit. On the other hand it agrees with the observations of De Sinety (77), Gegenbauer (76), Klaatsch (84), and Brouha (05) who reported the existence of a single primary duct in rodents and insectivorous mammals. Between the eighteenth and nineteenth days each primary duct in the rat fetus presents two secondary ...

The occipital bone has an interesting developmental history. Phylogenetically, the base of the bone is the cranial most serial homologue of the vertebral series of bones. The vertebral-like endochondral portion is joined by a large plate-like lamina that develops intramembranously. This bone can be somewhat plastic in its development, but a general plan is recognized as follows. The flat upper squamous portion of the bone superior to the highest nuchal line ossifies intramembranously in two lateral centers that appear during the second embryonic month. These centers will eventually join, but sometimes remain separate from the rest of the occipital elements becoming the so called interparietal bone. It is common for additional centers to appear in the membrane associated with the squama. These centers sometimes remain unfused to the rest of the squama becoming the sutural bones common to the occipitoparietal suture. The rest of the occipital bone, everything below the highest nuchal line, is ...

About 200 cases of MNTI have been reported until now. It is found to characteristically occur in the maxilla, more so from the intraoral side. Bone destruction and displacement of teeth often occur because of the intraosseous location in the maxilla. Other sites are the skull, mandible and the brain. The lesion is usually solitary and the mucosa over the lesion is usually intact. It has got a typical bluish color due to the presence of melanin. Although it is a benign tumor with a 2% chance of malignancy, it is locally aggressive. The majority of MNTI patients (there is no sexual predilection) present in the 1 year of life. The children present with swelling in the oral cavity, which often hinders feeding. The differential diagnosis is ameloblastoma, odontoma, odontogenic myxoma, fibroma, rhabdomyosarcoma, EwingÌs sarcoma, LangerhansÌ cell histiocytosis (LCH), non-HodgkinÌs lymphoma ...

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 ...

Neurocutaneous melanosis or neurocutaneous melanocytosis is a rare sporadic congenital disorder characterized by the presence of giant and/or multiple satellite congenital melanocytic nevi in the skin and benign melanocytic pigmentation of the leptomeninges. These two defining features were recognized more than a century ago. A third characteristic feature is proliferative nodules arising from giant nevi. The etiology is unknown, but neurocutaneous melanosis is considered a developmental disorder of melanocyte precursors from neural crest. The distinctive unique distribution of the congenital giant nevi that gives a garment appearance is also an expression of the neural crest. The neurological manifestations often appear in infancy.The special association of neurocutaneous melanosis with Dandy-Walker malformation complex may be explained by a common pathogenesis.

Neurocutaneous melanosis (NCM) is a rare congenital syndrome consisting of benign or malignant melanotic tumors of the central nervous system with large or numerous cutaneous melanocytic nevi. The Dandy-Walker complex (DWC) is characterized by an enlarged posterior fossa with high insertion of the tentorium, hypoplasia or aplasia of the cerebellar vermis, and cystic dilatation of the fourth ventricle. These each two conditions are rare, but NCM associated with DWC is even more rare. Most patients of NCM with DWC present neurological symptoms early in life such as intracranial hemorrhage, hydrocephalus, and malignant transformation of the melanocytes. We report a 14-year-old male patient who was finally diagnosed as NCM in association with DWC with extensive intracerebral and spinal cord involvement. ...

Large pigmented nevi, usually on the trunk, buttocks, or perineum. CNS function may be normal at birth, but MRI examination is necessary to exclude brain or spinal cord involvement. If the CNS is involved, thickening and pigmentation of the meninges with focal accumulation of melanotic cells or brainstem lesions is observed. Progressive pigmentation and thickening of the meninges lead to cerebral deterioration, increased intracranial pressure, mental retardation, seizures, hydrocephalus, cranial nerve palsies, and spinal cord compression. ...

N2 - Natriuretic peptides (NPs) are cyclic vasoactive peptide hormones with high therapeutic potential. Three distinct NPs (ANP, BNP, and CNP) can selectively activate natriuretic peptide receptors, NPR-A and NPR-B, raising the cyclic GMP (cGMP) levels. Insulin-degrading enzyme (IDE) was found to rapidly cleave ANP, but the functional consequences of such cleavages in the cellular environment and the molecular mechanism of recognition and cleavage remain unknown. Here, we show that reducing expression levels of IDE profoundly alters the response of NPR-A and NPR-B to the stimulation of ANP, BNP, and CNP in cultured cells. IDE rapidly cleaves ANP and CNP, ...

A primitive, or undifferentiated, nerve cell is a cell in the brain or central nervous system that doesnt have a specific function. Primitive cells are often malignant (meaning they are often cancerous), and start to grow out of control. Doctors call the resulting tumors primitive neuroectodermal tumors, or PNETS.. Types of PNETs include medulloblastoma, posterior fossa PNET, supratentorial PNET, and pineoblastoma. All of these tumors are able to metastasize (spread) through the cerebrospinal fluid that surrounds the brain and the spinal cord.. PNET symptoms generally depend on the size and location of the tumor, but common symptoms include:. ...

Insulin-degrading enzyme (IDE) is a protease that cleaves insulin and other bioactive peptides such as amyloid-β. Knockout and genetic studies have linked IDE to Alzheimers disease and type-2 diabetes. As the major insulin-degrading protease, IDE is a candidate drug target in diabetes. Here we have used kinetic target-guided synthesis to design the first catalytic site inhibitor of IDE suitable for in vivo studies (BDM44768). Crystallographic and small angle X-ray scattering analyses show that it locks IDE in a closed conformation. Among a panel of metalloproteases, BDM44768 selectively inhibits IDE. Acute treatment of mice with BDM44768 increases insulin signalling and surprisingly impairs glucose tolerance in an IDE-dependent manner. These results confirm that IDE is involved in pathways that modulate short-term glucose homeostasis, but casts doubt on the general usefulness of the inhibition of IDE catalytic activity to treat diabetes. ...
