A Case Report of Malignant Infantile Osteopetrosis  

PubMed Central

Background Malignant infantile osteopetrosis (MIOP) presents early in life with extreme sclerosis of the skeleton and reduction of bone marrow spaces. Since there is a defect in the bone marrow, the disease can cause anemia, extramedullary hematopoiesis secondary to anemia leading to hepatosplenomegaly, cranial nerves compression and severe growth failure. This disorder is often lethal within the first decade of life because of secondary infections. Stem cell transplantation (SCT) remains the only curative therapy. Case Presentation We report a two-month old male infant, diagnosed as MIOP while investigating the cause of hepatosplenomegaly. The patient was referred for stem cell transplantation. Conclusion Malignant infantile osteopetrosis should be kept in mind as a rare cause of hepatosplenomegaly and the patient should be referred for stem cell transplantation before neurologic or visual impairment develops.

Infantile or Malignant Osteopetrosis: Case Report of Two Siblings  

PubMed Central

Infantile or Malignant osteopetrosis is a rare congenital disorder of bone resorption. It is caused by failure of osteoclasts to reabsorb immature bone. Severe infantile or malignant osteopetrosis present at birth or develops within the first few months of life. We are reporting here a case of two siblings with malignant osteopetrosis. Prominent clinical features included marked pallor, noisy respiration, progressive blindness and developmental delay.

Infantile osteomyelitis secondary to malignant osteopetrosis.  

PubMed

Osteopetrosis (OP) is a rare congenital disorder (present at birth) in which the bones become over dense. This results from an imbalance between the formation of bone and the resorption of the bone. Thickening of the bones which become abnormally dense due to an inherited defect in bone resorption, the process in which old bone is broken down and removed so that new bone can be added to the skeleton. Osteoclasts are the cells responsible for bone resorption. In osteopetrosis the osteoclasts do not perform normally. This flaw in bone resorption results in bones that are abnormally dense, yet are fragile and easily broken. Osteopetrosis is also known as Albers-Schonberg disease, generalized congenital osteosclerosis, ivory bones, marble bones, osteosclerosis fragilis generalisata. In this article, we have described about the diagnosis and medical and surgical management of osteopetrosis reported case to our hospital. PMID:23449725

Lentiviral gene transfer of TCIRG1 into peripheral blood CD34(+) cells restores osteoclast function in infantile malignant osteopetrosis.  

PubMed

Infantile malignant osteopetrosis (IMO) is a rare, lethal, autosomal recessive disorder characterized by non-functional osteoclasts. More than 50% of the patients have mutations in the TCIRG1 gene, encoding for a subunit of the osteoclast proton pump. The aim of this study was to restore the resorptive function of IMO osteoclasts by lentiviral mediated gene transfer of the TCIRG1 cDNA. CD34(+) cells from peripheral blood of five IMO patients and from normal cord blood were transduced with lentiviral vectors expressing TCIRG1 and GFP under a SFFV promoter, expanded in culture and differentiated on bone slices to mature osteoclasts. qPCR analysis and western blot revealed increased mRNA and protein levels of TCIRG1, comparable to controls. Vector corrected IMO osteoclasts generated increased release of Ca(2+) and bone degradation product CTX-I into the media as well as increased formation of resorption pits in the bone slices, while non-corrected IMO osteoclasts failed to resorb bone. Resorption was approximately 70-80% of that of osteoclasts generated from cord blood. Furthermore, transduced CD34(+) cells successfully engrafted in NSG-mice. In conclusion we provide the first evidence of lentiviral-mediated correction of a human genetic disease affecting the osteoclastic lineage. PMID:23907031

Lectin histochemistry of infantile lysosomal storage disease associated with osteopetrosis.  

PubMed

In infantile lysosomal storage disease associated with osteopetrosis the nature of the enzyme deficiency as well as the type of material accumulated are both unknown. We used lectin histochemistry to characterize the storage material of previously reported cases. Using paraffin sections neurons stained positively with Luxol fast blue (LFB), periodic acid-Schiff (PAS), Concanavalia ensiformis agglutinin, Datura stramonium agglutinin, Griffonia simplicifolia-I, Lens culinaris agglutinin, Ricinus communis agglutinin-I, succinylated wheat germ agglutinin and wheat germ agglutinin, indicating an accumulation of fucosylated N-glycosidically linked oligosaccharides containing beta- and alpha-galactosyl residues and compounds containing N-acetyllactosamine. Reticuloendothelial cells in liver and in spleen did not stain with LFB, but did stain with PAS and the above lectins. These results indicate that there is storage of both carbohydrates and lipids in neurons, and stored carbohydrates with similar residues in reticuloendothelial cells in this disease, where the primary defect is still unknown.

Osteopetrosis.  

PubMed

Osteopetrosis is a rare disease that occurs when a child has an unequal balance between new bone growth and elimination of old bone. Children with this entity are able to make new bone tissue, but are not able to break down and eliminate old bones, which is essential for normal bone growth. These thickened and enlarged bones are very weak. These children can exhibit: failure to thrive, macrocephaly, anemia, deafness, and blindness. We will present a case of osteopetrosis, esotropia, and amblyopia of a 7-year-old boy and will discuss the pathophysiology and treatment. PMID:24141761

Infantile osteopetrosis, craniosynostosis, and Chiari malformation type I with novel OSTEM1 mutation  

PubMed Central

We report a case of a 9-month-old Arab infant, with novel OSTEM mutation and unpublished triad of osteopetrosis (OP), craniosynostosis (CS), and Chiari malformation type I (CM1). The index presented with progressive irritability, abnormal movements, following an accidental fall. The history revealed early onset of irritability, progressive visual loss, and global developmental delay, more prominent at the gross motor level and a suspected congenital cytomegalovirus infection. The pregnancy was uneventful with subsequent unremarkable delivery. The parents are Arabs?first cousins with no apparent symptoms or signs of bone disease. Three dimensional brain computed tomography (CT) showed ventriculomegaly, thick calvaria, and CS of the coronal and sagittal sutures. Patient had signs of left lower motor neuron facial palsy, and CT of petrous bones confirms the presence of osteopetrotic petrous with slim mastoid portions of the facial nerve canals both sides. Brain magnetic resonance imaging showed CM1. Skeletal survey showed sclerotic skeleton. He needed ventriculoperitoneal shunt and died at 18 months of age. Molecular testing for OSTEM1 gene revealed novel homozygous mutation that segregated from his parents. This novel OSTEM1 gene novel mutation and the combination of OP, infantile CS, and CM1 is to our knowledge never been reported.

Stem cell transplantation in children with infantile osteopetrosis is associated with a high incidence of VOD, which could be prevented with defibrotide.  

PubMed

Malignant infantile osteopetrosis (MIOP) is a rare hereditary disorder of osteoclast function, which can be reversed by hematopoietic stem cell transplantation (SCT). We observed a high incidence of hepatic veno-occlusive disease (VOD) in transplanted patients and explored the prevention of this complication by using defibrotide (DF) as a prophylaxis. Twenty children with MIOP were consecutively transplanted in our center between 1996 and 2005. Eleven of these patients were transplanted between 1996 and 2001 and experienced an overall incidence of VOD of 63.6% (7/11). VOD was severe in three patients and one patient succumbed to VOD-related multi-organ failure. Owing to this very high incidence of VOD, DF prophylaxis was initiated in nine patients consecutively transplanted between 2001 and 2005. In this group, only one patient (11.1%) was diagnosed with moderate VOD. We report here a very high risk in patients with MIOP to develop VOD after transplantation. Prophylactic DF was implemented in our current transplant protocol and reduced the VOD rate significantly in this high-risk population. PMID:16953210

Importance of neurological assessment before bone marrow transplantation for osteopetrosis  

PubMed Central

Neurological complications of malignant infantile osteopetrosis are well recognised; successful bone marrow transplantation, when performed early in life, can prevent or halt some of them. In a subgroup of infants osteopetrosis is associated with primary retinal degeneration and/or generalised neurodegeneration. Bone marrow transplantation, in spite of being successful in correcting the osseous and haematological abnormalities, does not influence the progressive course of the neurodegenerative disorder. Thus, the recognition of this subgroup of infants with a very poor prognosis is essential before deciding on bone marrow transplantation.??

A phenocopy of CAII deficiency: a novel genetic explanation for inherited infantile osteopetrosis with distal renal tubular acidosis  

PubMed Central

We report the molecular genetic investigation of two consanguineous kindreds where osteopetrosis and distal RTA (dRTA) were both manifest. One kindred harbours a novel homozygous frameshift alteration in CA2. In the other, CAII levels were normal despite a similar clinical picture, and we excluded defects in CA2. In this kindred, two separate recessive disorders are penetrant, each affecting a different, tissue specific subunit of the vacuolar proton pump (H+-ATPase), providing a highly unusual, novel genetic explanation for the coexistence of osteopetrosis and dRTA. The osteopetrosis is the result of a homozygous deletion in TCIRG1, which encodes an osteoclast specific isoform of subunit a of the H+-ATPase, while the dRTA is associated with a homozygous mutation in ATP6V1B1, encoding the kidney specific B1 subunit of H+-ATPase. This kindred is exceptional firstly because the coinheritance of two rare recessive disorders has created a phenocopy of CAII deficiency, and secondly because these disorders affect two different subunits of the H+-ATPase that have opposite effects on bone density, but which have only recently been determined to possess tissue specific isoforms.

Rescue of ATPa3-deficient murine malignant osteopetrosis by hematopoietic stem cell transplantation in utero  

PubMed Central

Autosomal recessive osteopetrosis (ARO) is a paradigm for genetic diseases that cause severe, often irreversible, defects before birth. In ARO, osteoclasts cannot remove mineralized cartilage, bone marrow is severely reduced, and bone cannot be remodeled for growth. More than 50% of the patients show defects in the osteoclastic vacuolar-proton-pump subunit, ATP6a3. We treated ATP6a3-deficient mice by in utero heterologous hematopoietic stem cell (HSC) transplant from outbred GFP transgenic mice. Dramatic phenotype rescue by GFP osteoclasts was obtained with engraftment, which was observed in most cases. Engraftment survived for variable periods. Recipients were not immunosuppressed, and graft-versus-host disease was not observed in all pups born after in utero treatment. Thus, differentiation of unmatched HSC transplanted in utero is sufficient to prevent fatal defects in ARO and may prevent complications of ARO unresponsive to conventional bone marrow transplantation. The presence of defective cells is not a barrier to the rescue of the phenotype by donor HSC.

We describe a rare case of desmoplastic infantile ganglioglioma that appears to have transformed into a glioblastoma multiforme tumor in a 5-year-old girl. The patient was initially treated with total removal of the tumor, without subsequent radiation therapy or chemotherapy. She was in good health for 3 years, but manifested a sudden onset of seizures, followed by severe headache, vomiting, and left-sided weakness. Cranial magnetic resonance imaging revealed a large mass with rim enhancement at the previously operated site. The mass was completely removed, and the pathology report revealed glioblastoma multiforme. Postoperative chemotherapy and radiation treatment were administered. She has been followed for 11 years, and is alive without recurrence. PMID:21763958

Oral aspects of osteopetrosis.  

PubMed

The characteristic feature of osteopetrosis is a lack of osteoclastic activity, leading to a series of somatic problems for afflicted persons. The life span of osteopetrotic patients has increased in recent years, thereby making oral aspects of the disease more evident. Four children with malignant osteopetrosis, born between 1967 and 1975, were examined. In all patients the anterior teeth were of normal shape, and erupted on schedule. Primary molars and all permanent teeth were greatly distorted, and remained totally or partly embedded in basal bone. Vertical growth of alveolar ridge was very limited. Where a fenestration of overlaying mucosa had occurred, a localized progressive osteitis developed, leading to soft tissue inflammation and, in two cases, extraoral mandibular fistulas. Peridontal attachment was very poor, spontaneous exfoliation had occurred in all patients. In two children tooth germs and necrotic bone were surgically removed. No beneficial effect of the treatment was observed. Large doses of antibiotics were needed to control recurring infections. No means of curing progressive osseous destruction of mandibular bone has been found. The general prognosis is poor. PMID:295483

Demonstration of an osteoblast defect in two cases of human malignant osteopetrosis. Correction of the phenotype after bone marrow transplant.  

PubMed Central

Osteopetrosis is an inherited disorder characterized by bone sclerosis due to reduced bone resorption. Here we report that human osteopetrotic osteoblast-like (Ob) cells express a defective phenotype in primary cultures in vitro, and that bone marrow transplant (BMT) corrects osteoblast function. DNA analysis at polymorphic short-tandem repeat loci from donor, recipient, and primary Ob-like cells pre-BMT and 2 yr post-BMT revealed that Ob were still of recipient origin post-BMT. Osteopetrotic Ob-like cells obtained pre-BMT showed normal and abnormal 1,25(OH)2D3-induced alkaline phosphatase (ALPase) and osteocalcin production, respectively, and failed to produce macrophage colony-stimulating factor (M-CSF) in response to IL-1a and TNF-alpha. These parameters were all normalized in primary Ob-like cells prepared 2 yr post-BMT. X-linked clonality analysis at the human androgen receptor (HUMARA) locus revealed that osteoblasts showed a polyclonal and an oligoclonal derivation pre- and post-BMT respectively, indicating that a limited number of progenitor reconstituted this population. Because osteoblasts were still of recipient origin post-BMT, this suggests that functional osteoclasts, due to the replacement of hematopoeitic cells, provided a local microenvironment in vivo triggering the differentiation and/or recruitment of a limited number of functional osteoblasts.

Osteopetrosis is a rare hereditary disease that was first described by a German Albert Schonberg in 1904. At least five types of osteopetrosis have been described. Among them osteopetrosis congenita (autosomal recessive) and osteopetrosis tarda (autosomal dominant) are most common. Here we are reporting a case of osteopetrosis tarda, who is a female of fifty years of age presented with fracture femur. Preoperatively there was no suspicion of osteopetrosis. She was only suspected while introducing an IM Nail during her fracture reduction. Diagnosis of osteopetrosis was confirmed post operatively by histopathology of medullary cavity of her femur.

HEREDITARY OSTEOPETROSIS OF THE RABBIT  

PubMed Central

The results of x-ray, hematologic, and chemical studies on cases of hereditary osteopetrosis of the rabbit are described and the resemblance of the findings to those of the severe juvenile form of human osteopetrosis is pointed out. The outstanding feature of the x-ray examinations was the homogeneous dense appearance of the entire skeleton. This condition was present at birth. In older cases there was evidence of some differentiation of bone structure. The hematologic studies showed that the disease was characterized by the development of a macrocytic anemia, thrombocytopenia, and a moderate myeloid leucocytosis. Other abnormal findings included high reticulocyte and normoblast counts, anisocytosis and poikllocytosis, and degenerative changes of the neutrophiles and lymphocytes. The chemical studies showed very low serum calcium values; serum phosphorus values were low during the first 4 weeks of life but were somewhat higher than normal levels in older cases. The serum phosphatase values were elevated. The blood sugar content was generally low. The blood cholesterol values were generally high. The liver glycogen values were small especially in older cases and those for muscle glycogen were somewhat smaller than normal values.

Desmoplastic infantile astrocytoma: recurrence with malignant transformation into glioblastoma: a case report.  

PubMed

Desmoplastic infantile astrocytoma (DIA) is an uncommon brain tumor of early infancy. The tumor is characterized by a lobar location, glial histology, and excellent prognosis after surgical removal. DIA and a similar tumor, desmoplastic infantile ganglioglioma (DIG) have been considered to be benign neoplasms, but the prognosis of DIA and DIG is currently under question as atypical and aggressive clinical features of the tumors have been reported. We encountered a patient who was diagnosed with DIA at the age of 22 months and exhibited tumor recurrence 8 years later. Surgical removal of the recurred tumor revealed that the tumor had transformed to overt glioblastoma. This case demonstrates that DIA is not an absolutely benign tumor and that careful clinical surveillance is needed during the follow-up period. PMID:21947035

Osteopetrosis with Chiari I malformation: presentation and surgical management.  

PubMed

Osteopetrosis is a heterogeneous group of rare, inherited disorders of the skeleton that results in neurological manifestations due to restriction of growth of cranial foramina and calvarial thickening. A 25-year-old woman with a history of autosomal dominant osteopetrosis presented to the authors' institution with headache worsened by exertion and radiating from the occipital region forward with episodes of choking/coughing when eating and a loss of gag reflex on physical examination. On MR imaging, she was found to have severe posterior fossa calvarial thickening resulting in a small posterior fossa and tonsillar ectopia of 9 mm and compression and deformation of the brainstem. She underwent posterior fossa craniectomy, foramen magnum decompression, and partial C-1 laminectomy with external durotomy. The patient did well postoperatively with resolution of symptoms. This case describes a new neurological manifestation of autosomal dominant osteopetrosis. To the authors' knowledge, this report represents the first described case of extreme posterior fossa calvarial thickening from autosomal dominant osteopetrosis with associated Chiari I malformation (CM-I) requiring posterior fossa decompression and extradural decompression. Given previously published MR imaging data that demonstrate the association of osteopetrosis and CM may be more common than in this case alone, the authors discuss the need for further investigation of the incidence of CM-I in patients with autosomal dominant osteopetrosis. Additionally, they review osteopetrosis and other diagnoses of calvarial hyperostosis presenting as CM-I. PMID:21456907

A case of autosomal dominant osteopetrosis type II with a novel TCIRG1 gene mutation.  

PubMed

Osteopetrosis is a rare genetic disorder characterized by increased bone mineral density (BMD) due to osteoclast failure. T-cell immune regulator 1 (TCIRG1) plays crucial roles on osteoclast function, and its mutation causes autosomal recessive osteopetorosis. However, mutations in TCIRG1 have never been identified in autosomal dominant osteopetrosis (ADO). A 3-year-old boy was first presented to the clinic because of spontaneous radius and femur fractures. He has optic atrophy. The areal BMD at the lumbar spine was 1274 g/cm2 (233% of normal). Laboratory tests revealed no remarkable abnormal findings, including anemia, except for extremely elevated serum tartrate-resistant acid phosphatase-5b (14,600 mU/dL). Radiographically, the skull base, pelvis, and vertebrae showed a focal sclerosis. Genetic analysis revealed a novel de novo heterozygous missense mutation (His242Arg). Taken together with the mutation, his mild clinical features were diagnosed as ADO. This case implies that TCIRG1 could become a genetic candidate for ADO in addition to malignant forms such as ARO.

Oligodontia associated with osteopetrosis: a rare case report.  

PubMed

Osteopetrosis is a descriptive term that refers to a group of rare hereditary disorders of the skeleton characterized by increased density of the bones. It was first described in 1904 by Albers-Schonberg, a German radiologist. This disease varies greatly in its presentation and severity ranging from neonatal onset with life threatening conditions such as bone marrow failure to incidental finding of osteopetrosis on radiographs. Dental abnormality may be attributed to pathological changes in the bone. Dentists should be aware of patients with the disease because of its effect on osteoclast function which results in impaired wound healing. This paper presents the case of a five-year-old girl exhibiting oligodontia associated with osteopetrosis. PMID:22041010

Dental management in autosomal recessive (intermediate) osteopetrosis: a case report.  

PubMed

Osteopetrosis (Albers-Schonberg disease) is the name given to a group of diseases that affect the growth and remodeling of bones. It is characterized by overgrowth and sclerosis of bone, resulting in thickening and narrowing of the marrow cavities throughout the skeleton. The exact cause is unknown, although failure of bone resorption related to defective osteoclasts is considered to be the basis of the problem. These patients present a significant challenge to the dentist for management of jaw and dental problems, as the disease process demands special strategies which are often at variance with conventional dentistry. The purpose of this paper was to report the management and follow-up of a child with intermediate autosomal recessive osteopetrosis who primarily complained of dental problems. PMID:21462770

Infantile botulism.  

PubMed

We present the first two known cases of infantile botulism in Oklahoma. The first case was due to type B toxin; the second was due to type A toxin. Both cases demonstrate most of the classic features of what now appears to be the most common form of botulism. Infantile botulism is an underrecognized but reversible cause of hypotonia. In most cases, the prognosis is excellent with institution of appropriate supportive care. The recognition of cranial nerve palsies or a history of constipation should raise the suspicion of infantile botulism. Aminoglycoside antibiotics and other agents that may precipitate or exacerbate neuromuscular blockade should be used with extreme caution in hypotonic infants until the cause of the hypotonia is clearly identified.

Mérycisme infantile

Infantile rumination can be defined as self-induced regurgitation of previously swallowed food. Because it can lead to potential somatic complications and because it implies dysfunctional mother-child bonding, both a pediatric and psychiatric approach is needed. The treatment must be somatic (nutritional) and psychological (intensive nursing, mother-baby psychotherapy). Two case studies illustrate this rare but impressive picture.

Twenty four patients suffering from osteopetrosis caused by carbonic anhydrase II deficiency are colliged. This pathology seems to be frequent in Tunisia. Mental retardation is present in 52%, 85% of patients have short stature and 25% have optic atrophy. All affected subjects show craniofacial disproportion and dental anomalies. Twenty patients have at least one bone fracture. Metabolic acidosis is constant: it is profound during the first life decade. A severe selective reduction of carbonic anhydrase II in erythrocyte is confirmed in 18 cases. Osteosclerosis and defective skeletal modelling are constant, cerebral calcification can be seen at the scanner approximately at the age of two years and six months. All patients are homozygous for a splice junction mutation in intron 2 of the carbonic anhydrase II gene, this mutation does not seem to protect patients from bone fractures nor induce a severe metabolic acidosis.

Rapid gene identification in a Chinese osteopetrosis family by whole exome sequencing.  

PubMed

Osteopetrosis is a rare genetically heterogeneous disorder of bone metabolism characterized by increased skeleton density. In the past, standard methods for genetic diagnosis of osteopetrosis have primarily been performed by candidate gene screening and positional cloning. However, these methods are time and labor consumptive; and the genetic basis of approximately 30% of the cases is yet to be elucidated. Here, we employed whole exome sequencing of two affected individuals from an osteopetrosis family to identify a candidate mutation in CLCN7 (Y99C). It was identified from a total of 1757 and 1728 genetic variations found in either patient, which were then distilled using filtering strategies and confirmed using Sanger sequencing. We identified this mutation in six family members, while not in population matched controls. This mutation was previously found in osteopetrosis patients by other researchers. Our evolutionary analysis also indicated that it is under extremely high selective pressure, and is likely to be critical for the correct function of ClC-7, and thus is likely to be the responsible cause of disease. Collectively, our data further indicated that mutation (Y99C) may be a cause of osteopetrosis, and highlights the use of whole exome sequencing as a valuable approach to identifying disease mutations in a cost and time efficient manner.

Myofibroblastic malignancies.  

PubMed

Malignant tumors composed of myofibroblasts are increasingly being recognized, but their existence remains controversial. Currently accepted examples within this category represent spindle cell or pleomorphic neoplasms of the soft tissues with a spectrum of histological grades. Low- and intermediate-grade myofibrosarcomas are fascicular spindle cell neoplasms resembling fibrosarcoma or leiomyosarcoma. They infiltrate deep soft tissue with disproportionate involvement of head and neck sites and can recur locally but infrequently metastasize. They variably express myoid immunohistochemical markers, and their differential diagnosis includes benign myofibroblastic proliferations such as fasciitis and fibromatosis as well as other types of spindle cell sarcoma. High-grade (pleomorphic) myofibrosarcomas are an ultrastructurally defined subset of malignant fibrous histiocytoma, which they resemble in morphology and behavior. Inflammatory myofibroblastic tumor and infantile fibrosarcoma are neoplasms that have myofibroblastic features and have been included in this category, but they have distinctive genetic findings. This article reviews the concept of myofibrosarcoma and describes its variants. PMID:15220822

[Recurrent and metastatic infantile fibrosarcoma: a case report].  

PubMed

Infantile fibrosarcoma is a rare malignant tumor that usually occurs during the 1st year of life. It accounts for approximately 5-10% of all sarcomas in infants younger than 1 year of age. It usually has indolent progression and metastatic spread is rare. We report the case of a patient who had infantile fibrosarcoma of the trunk. At birth, the baby presented a soft tissue mass of the scapulothoracic region. Histopathological examination after complete surgical resection at first suggested an angioma. Reanalysis of the histology after a metastatic relapse resulted in the diagnosis of infantile fibrosarcoma, which was confirmed by the presence of the specific translocation seen in infantile fibrosarcoma (ETV6/NTRK3). This patient's progression was uncommon because he developed 3 metastatic relapses. The treatment consisted of surgery, chemotherapy, and radiation therapy. The patient is alive with persistent complete remission. We discuss the diagnostic and therapeutic issues of infantile fibrosarcoma. There is a risk of erroneous diagnosis in newborn infants between benign angiomatous tumor and infantile fibrosarcoma. The fusion transcript ETV6-NTRK3 resulting from the specific chromosomal translocation t(12;15)(p13;q25) is now a useful diagnostic tool for infantile fibrosarcoma. Surgery with wide resection is the mainstay of treatment. However, infantile fibrosarcoma is a chemosensitive tumor. If initial surgery cannot be done without mutilation or is impossible, preoperative chemotherapy should be given. The role of radiation therapy is still debated. PMID:21084177

Successful staged hip replacement in septic hip osteoarthritis in osteopetrosis: a case report  

PubMed Central

Background Osteopetrosis is a rare, inherited, bone disorder, characterized by osteosclerosis, obliteration of the medullary cavity and calcified cartilage. The autosomal dominant form is compatible with a normal life span, although fractures often result from minimal trauma, due to the pathologic nature of bone. Osteomyelitis is common in patients with osteopetrosis because of a reduced resistance to infection, attributed to the lack of marrow vascularity and impairment of white cell function. Only one case of osteomyelitis of the proximal third of the femur has been previously reported, treated with several repeated debridements and finally with femoral head resection. Here we present for the first time a case of a staged implant of a cementless total hip prosthesis for the treatment of a septic hip in femoral neck nonunion in osteopetrosis. Case presentation A 36-years-old woman, affected by autosomal dominant osteopetrosis was referred to our department because of a septic hip arthritis associated with femoral neck septic non-union, with draining fistulas. The infection occurred early after a plate osteosynthesis for a closed perthrocanteric fracture of the femur and persisted in spite of osteosynthesis removal, surgical debridement and external fixation. In our hospital the patient underwent accurate debridement, femoral head and greater trochanter resection, preparation of the diaphyseal intramedullary canal and implant of an antibiotic-loaded cement spacer. The spacer was exchanged after one month, due to infection recurrence and four months later, a cementless total hip arthroplasty was implanted, with no clinical and laboratory signs of infection recurrence at two years follow-up. Conclusions In case of hip septic arthritis and proximal femur septic non-union, femoral head resection may not be the only option available and staged total hip arthroplasty can be considered.

Human Osteoclast-Poor Osteopetrosis with Hypogammaglobulinemia due to TNFRSF11A (RANK) Mutations  

PubMed Central

Autosomal-Recessive Osteopetrosis (ARO) comprises a heterogeneous group of bone diseases for which mutations in five genes are known as causative. Most ARO are classified as osteoclast-rich, but recently a subset of osteoclast-poor ARO has been recognized as due to a defect in TNFSF11 (also called RANKL or TRANCE, coding for the RANKL protein), a master gene driving osteoclast differentiation along the RANKL-RANK axis. RANKL and RANK (coded for by the TNFRSF11A gene) also play a role in the immune system, which raises the possibility that defects in this pathway might cause osteopetrosis with immunodeficiency. From a large series of ARO patients we selected a Turkish consanguineous family with two siblings affected by ARO and hypogammaglobulinemia with no defects in known osteopetrosis genes. Sequencing of genes involved in the RANKL downstream pathway identified a homozygous mutation in the TNFRSF11A gene in both siblings. Their monocytes failed to differentiate in vitro into osteoclasts upon exposure to M-CSF and RANKL, in keeping with an osteoclast-intrinsic defect. Immunological analysis showed that their hypogammaglobulinemia was associated with impairment in immunoglobulin-secreting B cells. Investigation of other patients revealed a defect in both TNFRSF11A alleles in six additional, unrelated families. Our results indicate that TNFRSF11A mutations can cause a clinical condition in which severe ARO is associated with an immunoglobulin-production defect.

Infantile hemangioma is a vascular tumor that occurs in 5-10% of infants of European descent. A defining feature of infantile hemangioma is its dramatic growth and development into a disorganized mass of blood vessels. Subsequently, a slow spontaneous involution begins around one year of age and continues for four to six years. The growth and involution of infantile hemangioma is very different from other vascular tumors and vascular malformations, which do not regress and can occur at any time during childhood or adult life. Much has been learned from careful study of the tissue morphology and gene expression patterns during the life-cycle of hemangioma. Tissue explants and tumor-derived cell populations have provided further insight to unravel the cellular and molecular basis of infantile hemangioma. A multipotent progenitor cell capable of de novo blood vessel formation has been isolated from infantile hemangioma, which suggests that this common tumor of infancy, long considered to be a model for pathologic angiogenesis, may also represent pathologic vasculogenesis. Whether viewed as angiogenesis or vasculogenesis, infantile hemangioma represents a vascular perturbation during a critical period of post-natal growth, and as such provides a unique opportunity to decipher mechanisms of human vascular development.

SNX10 mutations define a subgroup of human autosomal recessive osteopetrosis with variable clinical severity.  

PubMed

Human Autosomal Recessive Osteopetrosis (ARO) is a genetically heterogeneous disorder caused by reduced bone resorption by osteoclasts. In 2000, we found that mutations in the TCIRG1 gene encoding for a subunit of the proton pump (V-ATPase) are responsible for more than one-half of ARO cases. Since then, five additional genes have been demonstrated to be involved in the pathogenesis of the disease, leaving approximately 25% of cases that could not be associated with a genotype. Very recently, a mutation in the sorting nexin 10 (SNX10) gene, whose product is suggested to interact with the proton pump, has been found in 3 consanguineous families of Palestinian origin, thus adding a new candidate gene in patients not previously classified. Here we report the identification of 9 novel mutations in this gene in 14 ARO patients from 12 unrelated families of different geographic origin. Interestingly, we define the molecular defect in three cases of "Västerbottenian osteopetrosis," named for the Swedish Province where a higher incidence of the disease has been reported. In our cohort of more than 310 patients from all over the world, SNX10-dependent ARO constitutes 4% of the cases, with a frequency comparable to the receptor activator of NF-?B ligand (RANKL), receptor activator of NF-?B (RANK) and osteopetrosis-associated transmembrane protein 1 (OSTM1)-dependent subsets. Although the clinical presentation is relatively variable in severity, bone seems to be the only affected tissue and the defect can be almost completely rescued by hematopoietic stem cell transplantation (HSCT). These results confirm the involvement of the SNX10 gene in human ARO and identify a new subset with a relatively favorable prognosis as compared to TCIRG1-dependent cases. Further analyses will help to better understand the role of SNX10 in osteoclast physiology and verify whether this protein might be considered a new target for selective antiresorptive therapies.

[Primary malignant bone tumors].

Among human neoplasms, primary malignant bone tumors are fairly rare. They present an incidence rate of roughly 10 cases per 1 million inhabitants per year. During childhood (<15 years), the percentage of malignant bone tumors amounts to 6% of all infantile malignancies. Only leukemia and lymphoma show a higher incidence in adolescence. Of all primary malignant bone tumors, 60% affect patients younger than 45 years and the peak incidence of all bone tumors occurs between 15 and 19 years. The most common primary malignant bone tumors are osteosarcoma (35%), chondrosarcoma (25%), and Ewing's sarcoma (16%). Less frequently (??5%) occurring tumors are chordoma, malignant fibrous histiocytoma of bone, and fibrosarcoma of bone. Vascular primary malignant tumors of bone and adamantinoma are very rare. Staging of the lesion is essential for systemic therapeutic decision-making and includes complete imaging and histo-pathological confirmation of the suspected entity. In most cases, this is established by open- or image-guided biopsy. Based on this information, an interdisciplinary tumor board will determine the individual therapeutic approach. Endoprosthetic or biological reconstruction following wide tumor resection is the most common surgical therapy for primary malignant bone tumors. There is vital importance in a thorough postoperative follow-up and continous after-care by a competent tumor center which is permanentely in charge of therapy. PMID:22130624

RANK-Dependent Autosomal Recessive Osteopetrosis: Characterization of Five New Cases With Novel Mutations  

PubMed Central

Autosomal recessive osteopetrosis (ARO) is a genetically heterogeneous disorder attributed to reduced bone resorption by osteoclasts. Most human AROs are classified as osteoclast rich, but recently two subsets of osteoclast-poor ARO have been recognized as caused by defects in either TNFSF11 or TNFRSF11A genes, coding the RANKL and RANK proteins, respectively. The RANKL/RANK axis drives osteoclast differentiation and also plays a role in the immune system. In fact, we have recently reported that mutations in the TNFRSF11A gene lead to osteoclast-poor osteopetrosis associated with hypogammaglobulinemia. Here we present the characterization of five additional unpublished patients from four unrelated families in which we found five novel mutations in the TNFRSF11A gene, including two missense and two nonsense mutations and a single-nucleotide insertion. Immunological investigation in three of them showed that the previously described defect in the B cell compartment was present only in some patients and that its severity seemed to increase with age and the progression of the disease. HSCT performed in all five patients almost completely cured the disease even when carried out in late infancy. Hypercalcemia was the most important posttransplant complication. Overall, our results further underline the heterogeneity of human ARO also deriving from the interplay between bone and the immune system, and highlight the prognostic and therapeutic implications of the molecular diagnosis. © 2012 American Society for Bone and Mineral Research

Hereditary osteopetrosis of the rabbit; X-ray, hematologic, and chemical observations.  

PubMed

The results of x-ray, hematologic, and chemical studies on cases of hereditary osteopetrosis of the rabbit are described and the resemblance of the findings to those of the severe juvenile form of human osteopetrosis is pointed out. The outstanding feature of the x-ray examinations was the homogeneous dense appearance of the entire skeleton. This condition was present at birth. In older cases there was evidence of some differentiation of bone structure. The hematologic studies showed that the disease was characterized by the development of a macrocytic anemia, thrombocytopenia, and a moderate myeloid leucocytosis. Other abnormal findings included high reticulocyte and normoblast counts, anisocytosis and poikllocytosis, and degenerative changes of the neutrophiles and lymphocytes. The chemical studies showed very low serum calcium values; serum phosphorus values were low during the first 4 weeks of life but were somewhat higher than normal levels in older cases. The serum phosphatase values were elevated. The blood sugar content was generally low. The blood cholesterol values were generally high. The liver glycogen values were small especially in older cases and those for muscle glycogen were somewhat smaller than normal values. PMID:18103398

Hypohidrotic Ectodermal Dysplasia, Osteopetrosis, Lymphedema, and Immunodeficiency in an Infant with Multiple Opportunistic Infections.  

PubMed

Osteopetrosis, lymphedema, hypohidrotic ectodermal dysplasia, and immunodeficiency (OL-HED-ID) is a rare X-linked disorder with only three reported prior cases in the English-language literature. We describe a case of OL-HED-ID in a male infant who initially presented with congenital lymphedema, leukocytosis, and thrombocytopenia of unknown etiology at 7 days of age. He subsequently developed gram-negative sepsis and multiple opportunistic infections including high-level cytomegalovirus viremia and Pneumocystis jiroveci pneumonia. The infant was noted to have mildly xerotic skin, fine sparse hair, and periorbital wrinkling, all features suggestive of ectodermal dysplasia. Skeletal imaging showed findings consistent with osteopetrosis, and immunologic investigation revealed hypogammaglobulinemia and mixed T- and B-cell dysfunction. Genetic testing revealed a novel mutation in the nuclear factor kappa beta (NF-KB) essential modulator (NEMO) gene, confirming the diagnosis of OL-HED-ID. Mutations in the NEMO gene have been reported in association with hypohidrotic ectodermal dysplasia with immunodeficiency (HED-ID), OL-HED-ID, and incontinentia pigmenti. In this case, we report a novel mutation in the NEMO gene associated with OL-HED-ID. This article highlights the dermatologic manifestations of a rare disorder, OL-HED-ID, and underscores the importance of early recognition and prompt intervention to prevent life-threatening infections.

Infantile hemangiomas: A review  

PubMed Central

Infantile hemangiomas (IH) are the most common eyelid and orbital tumors of childhood. Although they are considered benign lesions that have a generally self-limited course, in the periocular region, they have the potential to cause amblyopia, strabismus, and severe disfigurement. The decision for treatment can be a source of anxiety for patients, parents, and physicians alike. There are numerous treatment modalities, including emerging therapies that may make treatment safer and more effective than ever before. This review discusses our current understanding of this disease, its management, and future therapies.

Aggressive Infantile Embryonal Tumors  

PubMed Central

Embryonal tumors are the most common brain tumors in infants less than 36 months of age. Histologically characterized as undifferentiated small round cell tumors with divergent patterns of differentiation, these include medulloblastoma, the most common form of embryonal tumor, as well as supratentorial primitive neuroectodermal tumor, medulloepithelioma, ependymoblastoma, medullomyoblastoma, melanotic medulloblastoma, and atypical teratoid/rhabdoid tumor. All are similarly aggressive and have a tendency to disseminate throughout the central nervous system. Because of efforts to avoid craniospinal irradiation in an attempt to lessen treatment-related neurotoxicity, management of these tumors in infants is unique. Outcomes remain similarly poor among all the tumor types and, therefore, identification of specific molecular targets that have prognostic and therapeutic implications is crucial. The molecular and clinical aspects of the three most common aggressive infantile embryonal tumors, medulloblastoma, supratentorial primitive neuroectodermal tumor, and atypical teratoid/rhabdoid tumor, are the focus of this review.

Infantile scurvy: a historical perspective.  

PubMed

Scurvy, a disease of dietary deficiency of vitamin C, is uncommon today. Among diseases, scurvy has a rich history and an ancient past. The Renaissance (14th to 16th centuries) witnessed several epidemics of scurvy among sea voyagers. In 1747, James Lind, a British Naval surgeon, performed a carefully designed clinical trial and concluded that oranges and lemons had the most antiscorbutic effect. Eventually, with the provision of lemon juice to the sea voyagers, scurvy became rare at sea. Infantile scurvy appeared almost as a new disease toward the end of the 19th century. The increased incidence of infantile scurvy during that period was attributed to the usage of heated milk and proprietary foods. Thomas Barlow described the classic clinical and pathologic features of infantile scurvy in 1883. Between 1907 and 1912, Holst and Frolich induced and cured scurvy in guinea pigs by dietary modification. In 1914, Alfred Hess established that pasteurization reduced the antiscorbutic value of milk and recommended supplementation of fresh fruit and vegetable juices to prevent scurvy. Such pioneering efforts led to the eradication of infantile scurvy in the United States. A brief history of infantile scurvy is provided. PMID:11581484

Twenty boys meeting the current DSM III criteria for infantile autism at the time of diagnosis were found to be hyperlexic in childhood and have been followed up for 7-17 years. The most striking feature of the group was the compulsion to decode written material without comprehension of its meaning, and this constituted a behavioral phenotype for this population. On word recognition tests such as the WRAT, they scored significantly higher than would be predicted on the basis of intelligence but demonstrated severe reading retardation on tests of reading comprehension such as the Gates-McGinitie. Major differences in intelligence were detected, ranging from severe mental retardation to very superior intelligence. Major differences in verbal and nonverbal abilities were also noted. Many were found to have unusually good memory, both visual and auditory, and the majority possessed an excellent stored vocabulary that could be used with written words despite the poverty of their expressive language. It is suggested that the presence of hyperlexia may identify a subgroup of autistic children. PMID:6480546

Infantile amnesia: a neurogenic hypothesis.  

PubMed

In the late 19th Century, Sigmund Freud described the phenomenon in which people are unable to recall events from early childhood as infantile amnesia. Although universally observed, infantile amnesia is a paradox; adults have surprisingly few memories of early childhood despite the seemingly exuberant learning capacity of young children. How can these findings be reconciled? The mechanisms underlying this form of amnesia are the subject of much debate. Psychological/cognitive theories assert that the ability to maintain detailed, declarative-like memories in the long term correlates with the development of language, theory of mind, and/or sense of "self." However, the finding that experimental animals also show infantile amnesia suggests that this phenomenon cannot be explained fully in purely human terms. Biological explanations of infantile amnesia suggest that protracted postnatal development of key brain regions important for memory interferes with stable long-term memory storage, yet they do not clearly specify which particular aspects of brain maturation are causally related to infantile amnesia. Here, we propose a hypothesis of infantile amnesia that focuses on one specific aspect of postnatal brain development--the continued addition of new neurons to the hippocampus. Infants (humans, nonhuman primates, and rodents) exhibit high levels of hippocampal neurogenesis and an inability to form lasting memories. Interestingly, the decline of postnatal neurogenesis levels corresponds to the emergence of the ability to form stable long-term memory. We propose that high neurogenesis levels negatively regulate the ability to form enduring memories, most likely by replacing synaptic connections in preexisting hippocampal memory circuits.

Modeling new therapies for infantile spasms  

PubMed Central

Summary Infantile spasms are the classical seizure type of West syndrome. Infantile spasms often herald a dismal prognosis, due to the high probability to evolve into intractable forms of epilepsies with significant cognitive deficits, especially if not adequately treated. The current therapies, high doses of adrenocorticotropic hormone, steroids or the GABA transaminase inhibitor vigabatrin, are often toxic and may not always be effective. The need to identify new therapies for spasms has led to the generation of a number of rodent models of infantile spasms. These include acute and chronic models of infantile spasms, with cryptogenic or symptomatic origin, many of which are based on specific etiologies. In this review, we will summarize the clinical experience with treating infantile spasms, the main features of the new animal models of infantile spasms and discuss their utility in the preclinical development of new therapies for infantile spasms.

Progenitor cells in infantile hemangioma  

PubMed Central

Infantile hemangioma is a vascular tumor that occurs in 5–10% of infants of European descent. A hallmark of infantile hemangioma is its lifecycle, which is divided into three stages. The proliferating phase spans the first year of postnatal life, and is characterized by cellular masses without a defined vascular architecture as well as nascent blood vessels with red blood cells evident within the lumenal space. The involuting phase begins around one year of age and continues for 3–5 years. Proliferation slows or stops in this phase, and histology shows that the blood vessel architecture becomes more obvious and vessel size is enlarged. The involuted phase is reached by 5–8 years of age, at which point blood vessels are replaced with a fibrofatty residuum and capillary-sized channels. The growth and involution life-cycle of infantile hemangioma is very different from other vascular tumors and vascular malformations, which do not regress and can occur at any time during childhood or adult life. Many laboratories have reported on the endothelial characteristics of the cellular masses that are prominent in the proliferating phase of infantile hemangioma, as well as their immature appearance. These studies, along with isolation and characterization of hemangioma-derived cell populations with progenitor cell properties have lead to an emerging hypothesis that hemangioma is caused by an abnormal or delayed differentiation of mesodermal progenitor cells into the disorganized mass of blood vessels. Here we discuss the literature that support this emerging hypothesis.

The diagnosis of malignant melanoma does not necessarily imply a grave prognosis. If the tumor is superficial, the chances of surgical cure may be good. Virtually all malignant melanoma arise from junctional nevi. Most nevi of the palms, soles, and genitalia are junctional nevi, therefore prophylactic excision of these nevi is recommended. The surgical treatment of malignant melanoma involves a wide excision and usually skin graft reconstruction. Chemotherapy and immunotherapy are used as adjuncts in the treatment of disseminated disease.

Vigabatrin monotherapy for infantile spasms.  

PubMed

Infantile spasms syndrome (IS) (also known as West syndrome) is an epileptic encephalopathy with a heterogeneous etiology. One of the most common specific causes is tuberous sclerosis, diagnosed in almost 10% of the affected infants. Adrenocorticotropic hormone or steroids have been the preferred treatments for IS for several decades. Clinical studies have shown that vigabatrin is superior to placebo in decreasing the frequency of infantile spasms. In tuberous sclerosis, vigabatrin may be considered the first-line treatment for IS. The mode of action is increasing concentrations of the inhibitory neurotransmitter GABA in the brain. The use of vigabatrin is limited by a serious adverse effect, permanent visual field constriction, which may affect 6-7% of exposed infants. Treatment choices are based on balancing the potential adverse effects against the risk of catastrophic cognitive and behavioral outcomes caused by uncontrolled spasms. PMID:22364326

Infantile colic, facts and fiction.  

PubMed

Infantile colic is one of the major challenges of parenthood. It is one of the common reasons parents seek medical advice during their child's first 3 months of life. It is defined as paroxysms of crying lasting more than 3 hours a day, occurring more than 3 days in any week for 3 weeks in a healthy baby aged 2 weeks to 4 months. Colic is a poorly understood phenomenon affecting up to 30% of babies, underlying organic causes of excessive crying account for less than 5%. Laboratory tests and radiological examinations are unnecessary if the infant is gaining weight normally and has a normal physical examination. Treatment is limited and drug treatment has no role in management. Probiotics are now emerging as promising agents in the treatment of infantile colic. Alternative medicine (Herbal tea, fennel, glucose and massage therapy) have not proved to be consistently helpful and some might even be dangerous. In conclusion infantile colic is a common cause of maternal distress and family disturbance, the cornerstone of management remains reassurance of parents regarding the benign and self-limiting nature of the illness. There is a critical need for more evidence based treatment protocols. PMID:22823993

[Peculiarities of organic psychic infantilism in adolescents].  

PubMed

An aim of the study was to specify peculiarities of the clinical dynamics of organic psychic infantilism and psychopathological presentations of this disorder in adolescence. A significant prevalence of psychic infantilism caused by organic CNS damage in patients seeking psychiatric help in adolescence and a negative effect of this disorder on social adaptation in this period of life were found. Sixty-seven patients, aged 15-18 years, (ICD-10 diagnosis F06) with signs of psychic infantilism were studied. In these cases, psychic infantilism encompassed all aspects of mental activity and manifested itself as a constant personality trait that caused the infantile type of reaction to the most of life situations. The clinical heterogeneity of organic infantilism determined by the different degree of psychic immaturity in some areas of psychic activity and concomitant encephalopathy symptoms was noted. This allowed to single out 3 groups of patients: with domination of psychic infantilism in volition (28 patients), in emotional sphere (21 patients) and immaturity of cognitive functions (20 patients). The clinical heterogeneity of psychic infantilism likely reflects the character of CNS damage (localization and time of the damage) and specifics of related organic dysontogenesis. PMID:20032950

These are metabolically the most active structures in the brain, which makes them vulnerable to many injurious factors. It is my belief that the high metabolic rate in the brainstem nuclei could support a control function for multiplexing of neural pathways, and that if this control is lost it may result in the defects of awareness and responsiveness seen in autistic children.

Skeletal manifestations of infantile scurvy.  

PubMed

Recent investigations of human skeletal material from the historic St. Martin's cemetery, England, found a range of abnormal lesions in six infants that are almost certainly related to scurvy. Porous and proliferative bone lesions affecting the cranial bones and scapulae were found, and this paper presents images obtained using both macroscopic and scanning electron microscope examination of the lesions. Previous work on infantile scurvy (Ortner et al., 1997-2001) relied heavily on changes at the sphenoid, which is often missing in archaeological bone, so the identification of changes attributable to scurvy on other cranial bones and the scapulae is encouraging. The ability to recognize changes related to scurvy on a range of bones will ensure an enhanced potential for recognition of this disease in future research involving archaeological bone. Research on historical documents from Birmingham dating to the eighteenth and nineteenth centuries, combined with the probable cases of scurvy identified, supports the view that the paucity of cases of infantile scurvy from the archaeological record reflects a lack of understanding and recognition of bone manifestations, rather than a lack of occurrence in this period. Changes linked to scurvy were only found in infants from the poorer sections of the community from St. Martin's, and this is almost certainly linked to patterns of food consumption and may be related to shortages of potatoes, due to blight, experienced during this period.

Prognostic potential of precise molecular diagnosis of Autosomal Recessive Osteopetrosis with respect to the outcome of bone marrow transplantation  

PubMed Central

Hematopoietic stem cell transplantation (HSCT) is often the only practical approach to fatal genetic defects. One of the first pathologies which HSCT was applied to was Autosomal Recessive Osteopetrosis (ARO), a rare genetic bone disease in which a deficit in bone resorption by osteoclasts leads to increased bone density and secondary defects. The disease is often lethal early in life unless treated with HSCT. In utero transplantation (IUT) of the oc/oc mouse, reproducing the clinical features of a subset of ARO, has demonstrated that the quality of life and the survival of transplanted animals are greatly improved, suggesting that a similar protocol could be applied to humans. However, recently the dissection of the molecular bases of the disease has shown that ARO is genetically heterogeneous and has revealed the presence of subsets of patients which do not benefit from HSCT. This observation highlights the importance of molecular diagnosing ARO to identify and establish the proper therapies for a better prognosis. In particular, on the basis of experimental results in murine models, efforts should be undertaken to develop approaches such as IUT and new pharmacological strategies.

Malignant mesothelioma  

PubMed Central

Malignant mesothelioma is a fatal asbestos-associated malignancy originating from the lining cells (mesothelium) of the pleural and peritoneal cavities, as well as the pericardium and the tunica vaginalis. The exact prevalence is unknown but it is estimated that mesotheliomas represent less than 1% of all cancers. Its incidence is increasing, with an expected peak in the next 10–20 years. Pleural malignant mesothelioma is the most common form of mesothelioma. Typical presenting features are those of chest pain and dyspnoea. Breathlessness due to a pleural effusion without chest pain is reported in about 30% of patients. A chest wall mass, weight loss, sweating, abdominal pain and ascites (due to peritoneal involvement) are less common presentations. Mesothelioma is directly attributable to occupational asbestos exposure with a history of exposure in over 90% of cases. There is also evidence that mesothelioma may result from both para-occupational exposure and non-occupational "environmental" exposure. Idiopathic or spontaneous mesothelioma can also occur in the absence of any exposure to asbestos, with a spontaneous rate in humans of around one per million. A combination of accurate exposure history, along with examination radiology and pathology are essential to make the diagnosis. Distinguishing malignant from benign pleural disease can be challenging. The most helpful CT findings suggesting malignant pleural disease are 1) a circumferential pleural rind, 2) nodular pleural thickening, 3) pleural thickening of > 1 cm and 4) mediastinal pleural involvement. Involvement of a multidisciplinary team is recommended to ensure prompt and appropriate management, using a framework of radiotherapy, chemotherapy, surgery and symptom palliation with end of life care. Compensation issues must also be considered. Life expectancy in malignant mesothelioma is poor, with a median survival of about one year following diagnosis.

Desmoplastic infantile ganglioglioma -- a case report.  

PubMed

Desmoplastic infantile ganglioglioma is a very rare supratentorial tumor occurring in the first two years of life. A five-month-old female infant presented with recurrent seizures, large head and loss of acquired milestones. Computerized Tomographic Scan of brain showed a large subarachnoid cyst with a solid intensely contrast enhancing tumor in the right temporoparietal region with severe degree of mass effect. Craniotomy and total excision of the tumor followed subsequently by subduro-peritoneal shunt for the extracerebral fluid collection was done. The child made good recovery. Histopathology revealed features of desmoplastic infantile ganglioglioma, viz., marked desmoplastic component with glial and neuronal elements. Immunohistochemistry showed positive staining for glial fibrillary acidic protein (GFAP) with areas of synaptophysin and chromogranin positivity. Desmoplastic infantile ganglioglioma is a rare tumor of infancy, which has excellent prognosis after total excision. No adjuvant therapy is required. This is the first Indian report of desmoplastic infantile ganglioglioma out of less than fifty cases reported worldwide. PMID:15472436

Malignant hyperthermia.  

PubMed Central

Malignant hyperthermia is a rare autosomal dominant trait that predisposes affected individuals to great danger when exposed to certain anaesthetic triggering agents (such as potent volatile anaesthetics and succinylcholine). A sudden hypermetabolic reaction in skeletal muscle leading to hyperthermia and massive rhabdomyolysis can occur. The ultimate treatment is dantrolene sodium a nonspecific muscle relaxant. Certain precautions should be taken before anaesthesia of patients known to be susceptible to malignant hyperthermia. These include the prohibition of the use of triggering agents, monitoring of central body temperature and expired CO2, and immediate availability of dantrolene. In addition, careful cleansing of the anaesthesia machine of vapours of halogenated agents is recommended. If these measures are taken, the chances of an MH episode are greatly reduced. When malignant hyperthermia-does occur in the operating room, prompt recognition and treatment usually prevent a potentially fatal outcome. The most reliable test to establish susceptibility to malignant hyperthermia is currently the in vitro caffeine-halothane contracture test. It is hoped that in the future a genetic test will be available.

Congenital infantile fibrosarcoma in a very low-birth-weight infant.  

PubMed

We describe a prenatally diagnosed case with congenital infantile fibrosarcoma, which is a rare malignant tumor, of which there have been only 14 cases reported in the English literature. A giant mass on the left thigh was detected at 24 weeks' gestation by prenatal ultrasonography. Because of its rapid growth and nonreassuring fetal status in utero, the baby was delivered by cesarean delivery at 27 weeks' gestation. The case was complicated by hemorrhagic anemia, coagulopathy, and cardiac failure, and a tumor resection was performed on day 3. As of age 2.5 years, he was healthy without evidence of recurrence. Because some fetal cases with congenital infantile fibrosarcoma have a poor prognosis, termination of pregnancy at an appropriate time and postnatal early treatment are crucial for successful treatment.

Infantile myofibromatosis is a rare fibrous tumor of infancy. The cutaneous solitary type has typically an excellent prognosis. However, histologically, it is important to rule out leiomyosarcoma, which has a poor prognosis. The low frequency of mitosis was definitive for a diagnosis of infantile myofibromatosis. We present a cutaneous solitary-type case of infantile myofibromatosis. Following incisional biopsy, the tumor remitted spontaneously.

Type II benign osteopetrosis (Albers-Schönberg disease) caused by a novel mutation in CLCN7 presenting with unusual clinical manifestations.  

PubMed

A 16-year-old male patient with type II autosomal dominant benign osteopetrosis (ADO) was genotyped and found to harbor a novel mutation in exon 25 of the gene encoding for the osteoclast-specific chloride channel, CLCN7, inherited from the father, who was asymptomatic. The patient had normal biochemical findings and acid-base balance, except for increased serum levels of creatine kinase, lactic dehydrogenase, and the bone formation markers bone alkaline phosphatase isoenzyme, osteocalcin and N-terminal type I collagen telopeptide/creatinine ratio. Unusual generalized osteosclerosis was observed together with a canonical increase in vertebral and pelvis bone mass. An affected first grade cousin presented with normal biochemical findings and a milder osteosclerotic pattern of the pelvis. At the cellular level, cultured osteoclasts from the patient showed increased motility, with lamellipodia, membrane ruffling and motile pattern of podosome distribution, all of which could have contributed to functional impairment of bone resorption. The present report documents a novel mutation of the CLCN7 gene causing osteopetrosis in a radiologically uncertain form of the diseases, with apparent incomplete penetrance. PMID:14564431

Desmoplastic infantile and non-infantile ganglioglioma. Review of the literature.  

PubMed

Desmoplastic gangliogliomas (DIG) are rare primary neoplasms that comprise 0.5-1.0% of all intracranial tumors. Clinically, there are two forms of DIG, the infantile and the non-infantile. These tumors invariably arise in the supratentorial region and commonly involve more than one lobe, preferentially the temporal and frontal. On neuroimaging are seen as large hypodense cystic masses with a solid isodense or slightly hyperdense superficial portion. The histologic diagnosis is characterized by the presence of three different cell lines: astrocytic, neuronal, and primitive neuroectodermal marker sites, which were demonstrable. The treatment of choice is radical surgical excision, and if this is done, achieved complete healing of the patient does not require additional treatment. A literature review of DIG was compiled through Medline/Ovid using the keywords "desmoplastic infantile ganglioglioma", "desmoplastic non-infantile ganglioglioma" covering the years 1984-2009. We present a review of a total of 113 cases of infantile (94) and non-infantile gangliogliomas (19) published to date, examining the clinical, radiologic, surgical, and pathological aspects, as well as the outcome. Desmoplastic gangliogliomas represent a rare tumor group with two well-defined age groups, the children and non-children. Desmoplastic infantile gangliogliomas are the most common and occur in children below 5 years of age, and the large majority of them present within the first year of life. Surgery is the treatment of choice and no complementary treatment is needed in cases of complete tumor resection. PMID:21246390

Severe phenotype in infantile facioscapulohumeral muscular dystrophy.  

PubMed

While much is known about the clinical course of adult FSHD, the third most common inherited muscular dystrophy, data on the "infantile phenotype" and especially on the progression of the disease in children are limited. We have followed a cohort of 7 patients with infantile FSHD for 9-25 years and here report the clinical and genetic findings in this group. Infantile FSHD is relatively rare, amounting to 4% of all of our FSHD patients. Despite some variability in the progression, infantile FSHD has a more consistent phenotype than adult FSHD. Although they had normal motor milestones, all patients showed facial weakness from early childhood, and subsequently were severely affected with rapid progression of the disease, marked muscular wasting, weakness, and hyperlordosis. None of the patients have shown signs of nocturnal hypoventilation or cardiomyopathy so far. No correlation was found between sex and the severity of phenotype whereas all but one patient had very short fragment sizes of the D4Z4 repeat. Only two patients had a de novo mutation: 3 patients inherited the mutation from a parent with somatic mosaicism, and one was inherited from a parent with classical adult FSHD. One patient was unusual in having one allele inherited from his father who showed somatic mosaicism and one allele with an additional de novo mutation. We conclude that infantile FSHD is a severe and rapidly progressive disease, and this needs to be taken into account in the advice given to patients diagnosed in early childhood. However, our data also suggest that the risk to an individual with classical FSHD of having a child with the infantile form is low. PMID:16934468

Malignant melanomas have one of the highest increases in incidence among malignancies. There are four histological types: superficial spreading melanoma, nodular melanoma, acrolentiginous melanoma and lentigo maligna melanoma. The TNM classification considers depth of infiltration (Clark's level), vertical tumor thickness (Breslow's thickness), ulceration of the primary tumor, satellites and in-transit metastases as well as regional lymph node and distant metastases. An adequate margin of clearance is important in primary resection. Sentinel lymph node biopsy is relevant in all melanomas with a Breslow tumor thickness >1 mm without clinically suspicious lymph nodes. In the case of lymph node metastases therapeutic dissection is recommended, in patients with in-transit metastases of the extremities hyperthermic isolated limb perfusion with cytostatic agents may be indicated. Resection of distant metastases can be useful if only one site is affected or a R0 resection is expected to be achieved. Adjuvant, neoadjuvant and palliative procedures, such as radiotherapy, chemotherapy and immunotherapy are additional treatment options. PMID:19444395

Malignant hyperthermia  

PubMed Central

Malignant hyperthermia (MH) is an uncommon, life-threatening pharmacogenetic disorder of the skeletal muscle. It presents as a hypermetabolic response in susceptible individuals to potent volatile anesthetics with/without depolarizing muscle relaxants; in rare cases, to stress from exertion or heat stress. Susceptibility to malignant hyperthermia (MHS) is inherited as an autosomally dominant trait with variable expression and incomplete penetrance. It is known that the pathophysiology of MH is related to an uncontrolled rise of myoplasmic calcium, which activates biochemical processes resulting in hypermetabolism of the skeletal muscle. In most cases, defects in the ryanodine receptor are responsible for the functional changes of calcium regulation in MH, and more than 300 mutations have been identified in the RYR1 gene, located on chromosome 19q13.1. The classic signs of MH include increase of end-tidal carbon dioxide, tachycardia, skeletal muscle rigidity, tachycardia, hyperthermia and acidosis. Up to now, muscle contracture test is regarded as the gold standard for the diagnosis of MHS though molecular genetic test is used, on a limited basis so far to diagnose MHS. The mortality of MH is dramatically decreased from 70-80% to less than 5%, due to an introduction of dantrolene sodium for treatment of MH, early detection of MH episode using capnography, and the introduction of diagnostic testing for MHS. This review summarizes the clinically essential and important knowledge of MH, and presents new developments in the field.

Pattern reversal evoked potentials in infantile spasms.

Visual evoked potentials in response to sinusoidal gratings of various spatial frequencies, alternating in contrast at 8 Hz were recorded from infants affected by an idiopathic form of infantile spasms (West syndrome). In two infants in whom the spasms began at 3 and 5 months of age, respectively, the VEP's were found to be depressed in amplitude at and around a spatial frequency of 3 and 5 c/deg, respectively. This midfrequency depression, which has never been reported in the literature for normal infants, suggests that infantile spasms in idiopathic patients may interfere at least temporarily with the development of visual function.

"Challenges in the management of fractures in osteopetrosis"! Review of literature and technical tips learned from long-term management of seven patients.  

PubMed

Osteopetrosis is a metabolic disorder with diminished bone resorption due to osteoclastic abnormality. It causes hard and brittle marble bone which fractures easily. Most of these fractures can be treated conservatively. Operative intervention when needed presents with unique technical challenges. While osteopetrotic hard bone may be penetrated with a drill bit; high friction and prolonged drilling can make the drill bit blunt. The heat generated can cause bone necrosis and break the drill bit. Besides this, brittleness of bones can cause intra-operative fractures. Due to the difficulties during the operation, the operative time may be prolonged thereby increasing the risk of post-operative infection. There is also a risk of delay in consolidation and non-union owning to impaired bone remodelling. We present an account of seven patients treated for various fracture related problems occurring throughout their life due to this disease. Difficulties encountered during their treatment prompted us to present some general management principles. PMID:19576583

Malignant hyperthermia  

PubMed Central

Malignant hyperthermia (MH) is a pharmacogenetic disorder of skeletal muscle that presents as a hypermetabolic response to potent volatile anesthetic gases such as halothane, sevoflurane, desflurane and the depolarizing muscle relaxant succinylcholine, and rarely, in humans, to stresses such as vigorous exercise and heat. The incidence of MH reactions ranges from 1:5,000 to 1:50,000–100,000 anesthesias. However, the prevalence of the genetic abnormalities may be as great as one in 3,000 individuals. MH affects humans, certain pig breeds, dogs, horses, and probably other animals. The classic signs of MH include hyperthermia to marked degree, tachycardia, tachypnea, increased carbon dioxide production, increased oxygen consumption, acidosis, muscle rigidity, and rhabdomyolysis, all related to a hypermetabolic response. The syndrome is likely to be fatal if untreated. Early recognition of the signs of MH, specifically elevation of end-expired carbon dioxide, provides the clinical diagnostic clues. In humans the syndrome is inherited in autosomal dominant pattern, while in pigs in autosomal recessive. The pathophysiologic changes of MH are due to uncontrolled rise of myoplasmic calcium, which activates biochemical processes related to muscle activation. Due to ATP depletion, the muscle membrane integrity is compromised leading to hyperkalemia and rhabdomyolysis. In most cases, the syndrome is caused by a defect in the ryanodine receptor. Over 90 mutations have been identified in the RYR-1 gene located on chromosome 19q13.1, and at least 25 are causal for MH. Diagnostic testing relies on assessing the in vitro contracture response of biopsied muscle to halothane, caffeine, and other drugs. Elucidation of the genetic changes has led to the introduction, on a limited basis so far, of genetic testing for susceptibility to MH. As the sensitivity of genetic testing increases, molecular genetics will be used for identifying those at risk with greater frequency. Dantrolene sodium is a specific antagonist of the pathophysiologic changes of MH and should be available wherever general anesthesia is administered. Thanks to the dramatic progress in understanding the clinical manifestation and pathophysiology of the syndrome, the mortality from MH has dropped from over 80% thirty years ago to less than 5%.

Multicentric infantile myofibromatosis: two perinatal cases.

Infantile myofibromatosis, the most common fibrous tumor of infancy, occurs in solitary, multiple, and generalized forms, with similar histology but different clinicopathologic and prognostic implications. This entity is a mesenchymal disorder characterized by the proliferation of fibrous tumors in the skin, muscles, viscera, bones, and subcutaneous tissues. Visceral lesions are associated with significant morbidity and mortality, generally within the first few months of life. They lead to failure to thrive, to infection, hemorrhage, or to the obstruction of vital organs. We describe two cases of multicentric myofibromatosis with significant in utero lesional growth, resulting in one fetal demise and one post-natal demise. To the best of our knowledge, this is the first report of a fetal death secondary to infantile myofibromatosis. PMID:17186271

Infantile and acquired nystagmus in childhood.  

PubMed

Nystagmus is an involuntary, periodic eye movement caused by a slow drift of fixation which is followed by a fast refixation saccade (jerk nystagmus) or a slow movement back to fixation (pendular nystagmus). In childhood most cases are benign forms of nystagmus: idiopathic infantile, ocular or latent nystagmus. They arise at the age of 3 months, without oscillopsia and show the absence of the physiologic opto-kinetic nystagmus. A full ophthalmologic evaluation is all that is needed in most cases: albinism, macular or optic nerve hypoplasia and congenital retinal dystrophies are the most common forms of ocular nystagmus. Idiopathic infantile nystagmus can be hereditary, the most common and best analyzed form being a mutation of the FRMD7 gene on chromosome Xq26.2. The mutation shows a mild genotype-phenotype correlation. In all female carriers the opto-kinetic nystagmus is absent and half had mild nystagmus. Latent nystagmus is part of the infantile esotropia syndrome and shows the unique feature of change of direction when the fixing eye changes: it is always beating to the side of the fixing eye. There is no cure for infantile nystagmus but therapeutic options include magnifying visual aids or eye muscle surgery at the age of 6-8 y in patients with head turn. Less than 20% of childhood nystagmus are acquired and need further neurological and imaging work-up. Alarming signs and symptoms are: onset after the age of 4 months, oscillopsia, dissociated (asymmetric) nystagmus, preserved opto-kinetic nystagmus, afferent pupillary defect, papilloedema and neurological symptoms like vertigo and nausea. The most common cause is due to pathology of the anterior optic pathway (e.g. optic nerve gliomas). It shows the same clinical feature of dissociated nystagmus as spasmus nutans but has a higher frequency as in INO. Other forms of acquired nystagmus are due to brainstem, cerebellar or metabolic diseases. PMID:22459007

Morphologic Overlap between Infantile Myofibromatosis and Infantile Fibrosarcoma: A Pitfall in Diagnosis.  

PubMed

Infantile myofibromatosis (IM) is a distinctive mesenchymal disorder with different clinical forms, including solitary, multicentric, and generalized with visceral involvement. A wide morphologic spectrum is encountered, with the extremes resembling congenital infantile fibrosarcoma (CIFS) and infantile hemangiopericytoma. We report a series of lesions with mixed features of CIFS and IM and compare them in order to further define their clinicopathologic features and the significance of the so-called composite fibromatosis. Seven lesions with unusual overlapping morphologic "composite" features of both IM and CIFS were selected from a series of 106 myofibroblastic lesions. Three cases classified as composite infantile myofibromatoses (COIM) were highly cellular tumors with a diffuse growth of primitive mesenchymal cells and focal features of IM combined with areas resembling infantile fibrosarcoma (IF). Four cases were classified as IF. Three of these exhibited a biphasic pattern with foci resembling IM, including whorls of primitive and spindle cells and perivascular and intravascular projections of myofibroblastic nodules, and the 4th had a close histologic resemblance to a primitive, immature IM. With reverse transcriptase polymerase chain reaction, the ETV6-NTRK3 transcript was absent in 3 COIM and was detected in 3 CIFS; the other CIFS had typical cytogenetic aberrations. On the basis of currently available information, COIM represents a morphologic variant of IM that can mimic IF. Careful histologic evaluation to detect the typical features of IM is essential to avoid classification as IF. Molecular analysis for the ETV6-NTRK3 gene fusion is an important diagnostic tool in this group of lesions. PMID:19006426

Propranolol treatment of infantile hemangioma endothelial cells: A molecular analysis.  

PubMed

Infantile hemangiomas (IHs) are non-malignant, largely cutaneous vascular tumors affecting approximately 5-10% of children to varying degrees. During the first year of life, these tumors are strongly proliferative, reaching an average size ranging from 2 to 20 cm. These lesions subsequently stabilize, undergo a spontaneous slow involution and are fully regressed by 5 to 10 years of age. Systemic treatment of infants with the non-selective ?-adrenergic receptor blocker, propranolol, has demonstrated remarkable efficacy in reducing the size and appearance of IHs. However, the mechanism by which this occurs is largely unknown. In this study, we sought to understand the molecular mechanisms underlying the effectiveness of ? blocker treatment in IHs. Our data reveal that propranolol treatment of IH endothelial cells, as well as a panel of normal primary endothelial cells, blocks endothelial cell proliferation, migration, and formation of the actin cytoskeleton coincident with alterations in vascular endothelial growth factor receptor-2 (VEGFR-2), p38 and cofilin signaling. Moreover, propranolol induces major alterations in the protein levels of key cyclins and cyclin-dependent kinase inhibitors, and modulates global gene expression patterns with a particular affect on genes involved in lipid/sterol metabolism, cell cycle regulation, angiogenesis and ubiquitination. Interestingly, the effects of propranolol were endothelial cell-type independent, affecting the properties of IH endothelial cells at similar levels to that observed in neonatal dermal microvascular and coronary artery endothelial cells. This data suggests that while propranolol markedly inhibits hemangioma and normal endothelial cell function, its lack of endothelial cell specificity hints that the efficacy of this drug in the treatment of IHs may be more complex than simply blockage of endothelial function as previously believed.

COSMC Is Overexpressed in Proliferating Infantile Hemangioma and Enhances Endothelial Cell Growth via VEGFR2  

PubMed Central

Infantile hemangiomas are localized lesions comprised primarily of aberrant endothelial cells. COSMC plays a crucial role in blood vessel formation and is characterized as a molecular chaperone of T-synthase which catalyzes the synthesis of T antigen (Gal?1,3GalNAc). T antigen expression is associated with tumor malignancy in many cancers. However, roles of COSMC in infantile hemangioma are still unclear. In this study, immunohistochemistry showed that COSMC was upregulated in proliferating hemangiomas compared with involuted hemangiomas. Higher levels of T antigen expression were also observed in the proliferating hemangioma. Overexpression of COSMC significantly enhanced cell growth and phosphorylation of AKT and ERK in human umbilical vein endothelial cells (HUVECs). Conversely, knockdown of COSMC with siRNA inhibited endothelial cell growth. Mechanistic investigation showed that O-glycans were present on VEGFR2 and these structures were modulated by COSMC. Furthermore, VEGFR2 degradation was delayed by COSMC overexpression and facilitated by COSMC knockdown. We also showed that COSMC was able to regulate VEGF-triggered phosphorylation of VEGFR2. Our results suggest that COSMC is a novel regulator for VEGFR2 signaling in endothelial cells and dysregulation of COSMC expression may contribute to the pathogenesis of hemangioma.

Gratification disorder ("infantile masturbation"): a review  

PubMed Central

Background: Little has been published on gratification disorder ("infantile masturbation") in early childhood. Aims: To expand on the profile of patients diagnosed with this condition. Methods: Retrospective case note review; Fraser of Allander Neurosciences Unit paediatric neurology outpatient department 1972–2002. Results: Thirty one patients were diagnosed (11 males and 20 females). Twenty one were referred for evaluation of possible epileptic seizures or epilepsy. The median age at first symptoms was 10.5 months (range 3 months to 5 years 5 months). The median age at diagnosis was 24.5 months (range 5 months to 8 years). The median frequency of events was seven times per week, and the median length 2.5 minutes. Events occurred in any situation in 10 children, and in a car seat in 11. Types of behaviour manifested were dystonic posturing in 19, grunting in 10, rocking in 9, eidetic imagery in 7, and sweating in 6. Two children had been previously diagnosed as having definite epilepsy. In nine cases home video was invaluable in allowing confident diagnosis. Conclusion: Gratification disorder, otherwise called infantile masturbation, is an important consideration in the differential diagnosis of epilepsy and other paroxysmal events in early childhood. Home video recording of events often prevents unnecessary investigations and treatments.

Anogenital malignancies and pre-malignancies.  

PubMed

Anogenital pre-malignancies and malignancies are frequently encountered. Aetiopathogenetically, human papillomavirus (HPV) infection plays a critical role. However, there is a variable degree of association of HPV infection with the development of anogenital malignancies. In this context, the high level of clinically unapparent HPV infection should be considered. Therefore, the question arises if the association with HPV is always causative. Besides HPV, pre-existent lichen sclerosus is also an important aetiopathologic factor in the development of anogenital malignancies. Common anogenital pre-malignancies comprise Bowen's disease (BD), Bowenoid papulosis (BP) and erythroplasia of Queyrat (EQ). From a clinical point of view, these are clearly different entities, but from a histopathological point of view, BD, BP and EQ are indistinguishable. They all represent forms of squamous intraepithelial neoplasia (IN). Intraepithelial neoplasia (IN) is not only restricted to squamous variants, but also includes non-squamous IN, Paget's disease (PD) and melanoma in situ. The risk of developing anogenital (pre)malignancies or other tumours is higher in immunocompromised and immunodeficient patients, in particular those suffering from human immunodeficiency virus (HIV) infection. Such risk factors will affect treatment and follow-up modalities. Regarding prophylactic measures, a relatively recent but very important development is the availability of HPV vaccination on a large scale. Momentarily, the effects of such vaccination, on a population-based scale, are not yet clear but will become apparent in the near future. Management of anogenital pre-malignancies and malignancies should be tailor-made and may be organized in a multidisciplinary fashion. PMID:21272092

Infantile botulism caused by Clostridium butyricum type E toxin.  

PubMed

The case of a 9-month-old boy with infantile botulism caused by Clostridium butyricum type E toxin is reported. Because infantile botulism is rare in Japan, it was difficult to diagnose it at an early stage. Electrophysiologic findings were useful for the diagnosis, and were characterized by incremental responses (waxing) to short intervals and rapid repetitive nerve stimulation. A bioassay for botulism in mice indicated that the patient had botulism due to type E or F botulinum toxin. C. butyricum type E was isolated from his feces, confirming the diagnosis. This is the first known case of infantile botulism due to C. butyricum type E toxin in Japan. PMID:18054696

The G215R Mutation in the Cl?/H+-Antiporter ClC-7 Found in ADO II Osteopetrosis Does Not Abolish Function but Causes a Severe Trafficking Defect  

PubMed Central

Background ClC-7 is a ubiquitous transporter which is broadly expressed in mammalian tissues. It is implied in the pathogenesis of lysosomal storage disease and osteopetrosis. Because of its endosomal/lysosomal localization it is still poorly characterized. Methodology/Principal Findings An electrophysiological characterization of rat ClC-7 using solid-supported membrane-based electrophysiology is presented. The measured currents show the characteristics of ClC-7 and confirm its function as a Cl?/H+-antiporter. We have used rat ClC-7 in CHO cells as a model system to investigate the functionality and cellular localization of the wt transporter and its variant G213R ClC-7 which is the analogue of human G215R ClC-7 responsible for autosomal dominant osteopetrosis type II. Our study shows that rat G213R ClC-7 is functional but has a localization defect in CHO cells which prevents it from being correctly targeted to the lysosomal membrane. The electrophysiological assay is tested as a tool for drug discovery. The assay is validated with a number of drug candidates. It is shown that ClC-7 is inhibited by DIDS, NPPB and NS5818 at micromolar concentrations. Conclusions/Significance It is suggested that the scenario found in the CHO model system also applies to the human transporter and that mislocalization rather than impaired functionality of G215R ClC-7 is the primary cause of the related autosomal dominant osteopetrosis type II. Furthermore, the robust solid-supported membrane-based electrophysiological assay is proposed for rapid screening for potential ClC-7 inhibitors which are discussed for treatment of osteoporosis.

Pathogenesis and therapies for infantile neuronal ceroid lipofuscinosis (infantile CLN1 disease).  

PubMed

The neuronal ceroid lipofuscinoses (NCL, Batten disease) are a group of inherited neurodegenerative diseases. Infantile neuronal ceroid lipofuscinosis (INCL, infantile Batten disease, or infantile CLN1 disease) is caused by a deficiency in the soluble lysosomal enzyme palmitoyl protein thioesterase-1 (PPT1) and has the earliest onset and fastest progression of all the NCLs. Several therapeutic strategies including enzyme replacement, gene therapy, stem cell-mediated therapy, and small molecule drugs have resulted in minimal to modest improvements in the murine model of PPT1-deficiency. However, more recent studies using various combinations of these approaches have shown more promising results; in some instances more than doubling the lifespan of PPT1-deficient mice. These combination therapies that target different pathogenic mechanisms may offer the hope of treating this profoundly neurodegenerative disorder. Similar approaches may be useful when treating other forms of NCL caused by deficiencies in soluble lysosomal proteins. Different therapeutic targets will need to be identified and novel strategies developed in order to effectively treat forms of NCL caused by deficiencies in integral membrane proteins such as juvenile neuronal ceroid lipofuscinosis. Finally, the challenge with all of the NCLs will lie in early diagnosis, improving the efficacy of the treatments, and effectively translating them into the clinic. This article is part of a Special Issue entitled: The Neuronal Ceroid Lipofuscinoses or Batten Disease. PMID:23747979

Infantile parkinsonism-dystonia: a dopamine "transportopathy"  

PubMed Central

The dopamine transporter (DAT) retrieves the neurotransmitter dopamine from the synaptic cleft at dopaminergic synapses. Variations in solute carrier family 6A, member 3 (SLC6A3/DAT1), the human gene encoding DAT, have been implicated in attention deficit hyperactivity and bipolar disorders, and DAT is a prominent site of action for drugs such as amphetamines and cocaine. In this issue of the JCI, Kurian et al. report that an autosomal recessive infantile parkinsonism-dystonia is caused by loss-of-function mutations in DAT that impair dopamine reuptake (see the related article beginning on page 1595). Though this might be predicted to result in dopamine excess in the synaptic cleft, it likely also causes depletion of presynaptic dopamine stores and possibly downregulation of postsynaptic dopamine receptor function, resulting in impairments in dopaminergic neurotransmission consistent with the clinical presentation. This is the first report of a genetic alteration in DAT function underlying a parkinsonian disorder.

Medial epiphysiolysis in severe infantile tibia vara.  

PubMed

Recurrent varus deformity and shortening frequently result following valgus osteotomy alone for advanced stage infantile tibia vara (ITV), due to the proximal medial physeal dysfunction which resembles a complete growth arrest in Langenskiöld grade III or greater lesions. Epiphysiolysis is a possible treatment alternative which, if successful, can restore symmetric proximal tibial growth and obviate the need for additional complex treatments to address recurrent angular deformity and limb length inequality. We reviewed 24 patients, ages 5-10 years, with 27 affected tibiae, who underwent epiphysiolysis of the proximal medial tibia combined with valgus osteotomy. The procedure was >80% successful in restoring growth and avoiding varus recurrence in children <7 years old. Patients >age 7, patients with relative undercorrection of their mechanical axis at the time of surgery, and patients with previous failed surgical treatment were more likely not to benefit from epiphysiolysis, and consequently alternative methods may be more appropriate.

Differential diagnosis in progressive infantile spastic tetraparesis.

Progressive infantile spastic tetraparesis spans a wide spectrum of partially rare differential diagnoses. Based on a clinical example the differential diagnostic thoughts are discussed in detail. Though juvenile motor neuron disease is a rare entity, it has to be kept in mind for differential diagnostics in cases of slowly progressive spastic tetraparesis, especially when a pseudobulbar palsy or distal amyotrophies add to the clinical picture. Electromyography can be helpful for early detection of lower motor neuron involvement. The glutamate antagonist riluzole slows the disease progression, but a causal treatment is not available, yet. Therefore symptomatic treatment of disturbing symptoms like muscle cramps, spasticity, pseudobulbar affect, dyspnea or dysphagia are of major interest. PMID:19008170

Infantile Hemangiomas Masquerading as Other Periocular Disorders  

PubMed Central

Periocular tumors are common in infancy. The most common periocular tumors are capillary hemangiomas, which are present in 1-2% of newborns and develop in 10%–12% of children by the age of 1 year old. Deep capillary hemangiomas may be more challenging to diagnose than superficial capillary hemangiomas and can be confused with other orbital lesions. Deep orbital hemangiomas can mimic teratoma, lymphangioma, rhabdomyosarcoma, metastatic neuroblastoma, and granulocytic sarcoma. In this paper, we describe 2 pediatric cases where previously diagnosed dermoid cyst and dacrocystocele were found to be capillary hemangiomas upon biopsy. Approaches to distinguish capillary hemangiomas from other periocular tumors are further discussed. To our knowledge, this is the first case report of periocular hemangiomas imitating a dermoid cyst and a dacrocystocele. These cases emphasize the importance of including infantile hemangiomas in the differential diagnosis of subcutaneous periocular abnormalities.

Intraosseous infantile myofibroma of the mandible  

PubMed Central

The myofibroma, especially the intraosseous variety, is an uncommon benign tumor that occurs primarily in children younger than 3 years of age. Since 1966, less than 40 cases of solitary myofibromas of the mandible have been reported in the literature. Myofibroblasts and spindle cells are predominantly found in this benign lesion. These cells are also commonly found in many lesions due to which great difficulty can be encountered in the diagnosis. A rare case of the intraosseous variety of an infantile myofibroma of the mandible diagnosed in a 10-month-old child has been reported. The tumor was completely excised via an intraoral approach and no recurrence has been noted 15 months postoperatively. A brief review of the differential diagnosis of this lesion in terms of its clinicopathologic, histologic, and immunohistochemical features is also discussed.

Rheumatic Diseases and Malignancies  

PubMed Central

ABSTRACT There are many studies which demonstrate a higher risk for malignancy in patients with rheumatic diseases. There have been a number of possible explanations for the differences in the risk of certain malignancies in patients with rheumatic disease, compared with general population, but a clear mechanism is difficult to identify. Rheumatoid syndromes may be associated with malignancy as paraneoplastic conditions, which can antedate the neoplasm diagnosis. On the other hand, autoimmune rheumatic diseases have a higher risk of malignancy by themselves or because of the immunosuppressant treatments.

Neuroradiological findings (MRS, MRI, SPECT) in infantile neuronal ceroid-lipofuscinosis (infantile CLN1) at different stages of the disease.  

PubMed

Infantile neuronal ceroid-lipofuscinosis (infantile CLN1) is a progressive and uniformly fatal lysosomal storage disease of the nervous system. The purpose of this study was to compare the findings of various radiological examinations of the brain in the course of infantile CLN1 in order to evaluate the relative usefulness of the methods and their potential for monitoring therapeutic interventions. We examined eight infantile CLN1 patients, 51 studies, in various stages of the disease--preclinical to late stage--with proton magnetic resonance spectroscopy (1H-MRS), MRI, and perfusion SPECT, and in addition three benzodiazepine (BZ) receptor ligand SPECT studies. Both 1H-MRS and MRI showed abnormal findings before clinical manifestations of the disease. Cortical hypoperfusion and loss of cortical BZ receptors revealed by SPECT appeared simultaneously with clinical signs. After the age of 4 years MRI and SPECT alterations progressed minimally, whereas 1H-MRS showed progressive deterioration of neurometabolism. Of the four methods used in this study, MRI proved to be the most practicable for diagnosing infantile CLN1; the final diagnosis of infantile CLN1 is confirmed by the characteristic clinical picture and DNA or PPT enzyme analysis. The combination of 1H- MRS and MRI could be most useful for monitoring therapeutic interventions. PMID:15002049

Elevated serum lactate dehydrogenase isoenzymes and aspartate transaminase distinguish Albers-Schönberg disease (Chloride Channel 7 Deficiency Osteopetrosis) among the sclerosing bone disorders.  

PubMed

Osteopetrosis (OPT) refers to the consequences of generalized failure of skeletal resorption during growth. Most cases are explained by loss-of-function mutation within the genes that encode either chloride channel 7 (CLCN7) or a vacuolar proton pump subunit (TCIRG1), each compromising acid secretion by osteoclasts. Patients suffer fractures and sometimes cranial nerve entrapment and insufficient medullary space for hematopoiesis. In 1996, we reported that a high serum level of the brain isoenzyme of creatine kinase (BB-CK), the CK of osteoclasts, characterizes OPT dueamong the sclerosing bone disorders (J Clin Endocrinol Metab. 1996;11:1438). Now, we show that elevation in serum of multiple lactate dehydrogenase (LDH) isoenzymes with aspartate transaminase (AST) distinguishes autosomal dominant OPT due to loss-of-function mutation in CLCN7 [Albers-Schönberg disease (A-SD)] among these conditions. Serum total LDH and AST levels as high as 3× and 2×, respectively, the upper limits of normal for age-appropriate controls, were persistent and essentially concordant in A-SD. Serum LDH was elevated in 7 of 9 children and in the 2 adults studied with A-SD. LDH isoenzyme quantitation showed excesses of LDH-2, -3, and -4. Neither total LDH nor AST increases were found in other forms of OPT, including bisphosphonate-induced OPT, or in 41 children and 6 adults representing 20 additional sclerosing bone disorders. Serum TRACP-5b and BB-CK also were markedly elevated in A-SD. Hence, high serum levels of several enzymes characterize A-SD. Elevated serum LDH isoenzymes and AST indicate a disturbance (of uncertain clinical significance) within multiple extraosseous tissues when there is CLCN7 deficiency. PMID:20499337

Benign familial infantile convulsions: phenotypic variability in a family.  

PubMed

Benign familial infantile convulsion is an autosomal dominant epilepsy syndrome characterized by seizures starting from 3 to 12 months and a favorable outcome. We present a Turkish family with benign familial infantile convulsions and report the clinical variability associated with this syndrome in three generations. All 11 affected members had benign infantile seizures, which were primarily generalized in all but one patient, who had partial seizures with secondary generalization. The seizures started within the first year and were accompanied by normal neurologic development and a good response to treatment with phenobarbital. In this family, the phenotype extended beyond infancy. The index patient had unilateral occipital spike and waves on electroencephalography (EEG), although he had no clinical seizures at 4 years of age. Follow-up EEG of this patient 1 year later showed that the discharges shifted to the occipital lobe of the other hemisphere. The grandmother of this patient had temporal lobe seizures as an adult, years after the remission of infantile convulsions. One of the patients experienced paroxysmal choreoathetosis during adolesence. Our findings highlight the intrafamilial phenotypic variability of benign familial infantile convulsions in a large pedigree with long-term follow-up. PMID:15996407

Role of connexins in infantile hemangiomas  

PubMed Central

The circulatory system is one of the first systems that develops during embryogenesis. Angiogenesis describes the formation of blood vessels as a part of the circulatory system and is essential for organ growth in embryogenesis as well as repair in adulthood. A dysregulation of vessel growth contributes to the pathogenesis of many disorders. Thus, an imbalance between pro- and antiangiogenic factors could be observed in infantile hemangioma (IH). IH is the most common benign tumor during infancy, which appears during the first month of life. These vascular tumors are characterized by rapid proliferation and subsequently slower involution. Most IHs regress spontaneously, but in some cases they cause disfigurement and systemic complications, which requires immediate treatment. Recently, a therapeutic effect of propranolol on IH has been demonstrated. Hence, this non-selective ?-blocker became the first-line therapy for IH. Over the last years, our understanding of the underlying mechanisms of IH has been improved and possible mechanisms of action of propranolol in IH have postulated. Previous studies revealed that gap junction proteins, the connexins (Cx), might also play a role in the pathogenesis of IH. Therefore, affecting gap junctional intercellular communication is suggested as a novel therapeutic target of propranolol in IH. In this review we summarize the current knowledge of the molecular processes, leading to IH and provide new insights of how Cxs might be involved in the development of these vascular tumors.

Surgical success rates in infantile esotropia.  

PubMed

An extensive literature search covering the last 35 years was undertaken to retrieve all English language articles reporting results of surgical management of infantile esotropia. Only 27 of the 48 studies retrieved met the minimum criteria which we established for inclusion in our analysis. The success rate for achieving some level of binocular vision was 22% in 1286 patients, while the overall cosmetic success rate was 63% in 2113 patients. Newer surgical procedures appear to be more effective in achieving cosmetic success. Although controversy still exists about the optimal time for surgery, the most reasonable approach appears to be the concept of performing surgery as soon as an accurate determination can be made of the deviation and associated characteristics, and only after attention has been directed to any accommodative component and treatment of amblyopia. Although approximately 60% of patients referred for surgery can be expected to achieve cosmetic improvement after the first operation, the need for multiple surgery is common. There is a trend toward recurrence of the strabismus, and the need for short interval, long-term optometric follow-up is essential. PMID:2644332

Infantile Spasms: A Critical Review of Emerging Animal Models  

PubMed Central

Infantile spasms is a developmental epilepsy syndrome with unique clinical and EEG features, a specific pattern of pharmacological responsiveness, and poor outcome in terms of cognition and epilepsy. Despite the devastating nature of infantile spasms, little is known about its pathogenesis. Until recently, there has been no animal model available to investigate the pathophysiology of the syndrome or to generate and test novel therapies. Now, several promising animal models have emerged, spanning the etiological spectrum from genetic causes (e.g., Down syndrome or Aristaless-related homeobox [ARX] mutation) to acquired causes (e.g., endogenous and exogenous toxins or stress hormones with convulsant activity or blockade of neural activity). These new models are discussed in this review, with emphasis on the insights each can provide for understanding, treating, and preventing infantile spasms.

Effect of captopril on infantile haemangiomas: a retrospective case series.

The mechanism of action of beta adrenergic blockers in the involution of infantile haemangioma (IH) remains unclear. It has been proposed that the renin-angiotensin pathway may play a role. We present a retrospective case series of 17 patients with IH who were treated with oral corticosteroid therapy and developed hypertension requiring treatment with the angiotensin converting enzyme inhibitor, captopril. All patients, with written documentation, demonstrated an improvement in their lesion at the start of oral corticosteroid therapy (n?=?14). Captopril alone did not sustain the corticosteroid-induced involution with a documented worsening of infantile haemangioma in seven out of 12 patients (58%). PMID:22671578

Rice water in treatment of infantile gastroenteritis.  

PubMed

In Singapore the World Health Organization's (WHO's) oral electrolyte solution for the treatment of infantile gastroenteritis has been used for 6 years and rice water has been used for 8 years. The rice water is the water used in preparing boiled rice or congee and is a slightly starchy solution. As the impression was that rice water was as effective as or even better than the oral electrolyte solution, a trial was conducted of the 2 solutions in babies with gastroenteritis admitted to the Department of Pediatrics of the National University of Singapore. Alternate cases were assigned consecutively to the oral electrolyte solution or to rice water. There were 63 patients on oral electrolyte and 67 on rice water. Milk was totally withdrawn for 24 hours after admission and the babies were put on 1 or the other oral solution. Intravenous 3.75% glucose and 0.23% saline was given at the same time to babies considered to be more dehydrated. On day 2, quarter strength powdered milk was given, followed by half strength on day 3, three-quarters strength on day 4, and full strength on day 5. Electrolyte and urea values were compared, both for "drip" versus "no drip" within oral treatment groups and between electrolyte solution and rice water groups (20 comparisons altogether). There were only 3 significant differences, and these might be explained by the intravenous drip and by the better water absorption from rice water than from the oral electrolyte solution. The most obvious difference in the 2 groups was in the effect on diarrhea (stools/day). Rice water cut down the number of stools more effectively than did oral electrolyte solution. No patient died, and there were no pathological sequelae in any of the 130 patients. Rice water can be tried as a more practical alternative to oral electrolyte solutions since there are problems with providing oral elecrolyte solutions to all babies with diarrhea in the developing countries and ensuring sterility.

Melanoma with rhabdoid features is an uncommon variant of malignant melanoma. Here, we describe a rare case of primary rhabdoid malignant melanoma. A 54-year-old man presented with a black tumor measuring 3×4 cm on the right forearm. Histologic sections showed a tumor mass with rhabdoid features composed entirely of polygonal neoplastic cells with eccentric nuclei, prominent nucleoli, and large hyaline cytoplasmic inclusions. The tumor cells were immunoreactive with HMB-45, S100, Fontana-Masson silver and vimentin, and negative for smooth muscle actin, CD68, CD34, CD99, synaptophysin, desmin, and PAS. The differential diagnosis for this tumor included malignant peripheral nerve sheath tumor, malignant peripheral neuroectodermal tumor and rhabdomyosarcoma. The patient was treated with a wide excision and a local skin graft. The excised tumor was entirely composed of rhabdoid tumor cells. No recurrence or metastasis was evident 4 months after removal. This article is relevant to rare cases of primary malignant melanomas showing rhabdoid tumor cells over the entire excised lesion.

Surveillance for gastrointestinal malignancies  

PubMed Central

Gastrointestinal (GI) malignancies are notorious for frequently progressing to advanced stages even in the absence of serious symptoms, thus leading to delayed diagnoses and dismal prognoses. Secondary prevention of GI malignancies through early detection and treatment of cancer-precursor/premalignant lesions, therefore, is recognized as an effective cancer prevention strategy. In order to efficiently detect these lesions, systemic application of screening tests (surveillance) is needed. However, most of the currently used non-invasive screening tests for GI malignancies (for example, serum markers such as alpha-fetoprotein for hepatocellular carcinoma, and fecal occult blood test, for colon cancer) are only modestly effective necessitating the use of highly invasive endoscopy-based procedures, such as esophagogastroduodenoscopy and colonoscopy for screening purposes. Even for hepatocellular carcinoma where non-invasive imaging (ultrasonography) has become a standard screening tool, the need for repeated liver biopsies of suspicious liver nodules for histopathological confirmation can’t be avoided. The invasive nature and high-cost associated with these screening tools hinders implementation of GI cancer screening programs. Moreover, only a small fraction of general population is truly predisposed to developing GI malignancies, and indeed needs surveillance. To spare the average-risk individuals from superfluous invasive procedures and achieve an economically viable model of cancer prevention, it’s important to identify cohorts in general population that are at substantially high risk of developing GI malignancies (risk-stratification), and select suitable screening tests for surveillance in these cohorts. We herein provide a brief overview of such high-risk cohorts for different GI malignancies, and the screening strategies that have commonly been employed for surveillance purpose in them.

Immunotherapy of Genitourinary Malignancies  

PubMed Central

Most cancer patients are treated with some combination of surgery, radiation, and chemotherapy. Despite recent advances in local therapy with curative intent, chemotherapeutic treatments for metastatic disease often remain unsatisfying due to severe side effects and incomplete long-term remission. Therefore, the evaluation of novel therapeutic options is of great interest. Conventional, along with newer treatment strategies target the immune system that suppresses genitourinary (GU) malignancies. Metastatic renal cell carcinoma and non-muscle-invasive bladder caner represent the most immune-responsive types of all human cancer. This review examines the rationale and emerging evidence supporting the anticancer activity of immunotherapy, against GU malignancies.

Desmoplastic mesothelioma is a rare subtype of diffuse malignant mesothelioma. A 72-year-old woman from East Anatolia presented with chest pain. The images of body positron emission tomography revealed irregular, left pleural thickening involving mediastinal and diaphragmatic surfaces with hypermetabolic characterization. The diagnosis of desmoplastic malignant mesothelioma was confirmed by minithoracotomy and immunohistochemical staining with pan-cytokeratin, cytokeratin 5/6, calretinin, carcinoembryonic antigen, thyroid transcription factor-1, CD15, and HMB-45 on the biopsy specimen. This case is unique in terms of the reporting patient being from a nonendemic area for asbestos-related diseases and in terms of its rare histopathology. PMID:23609252

Treatment of infantile spasms: emerging insights from clinical and basic science perspectives.  

PubMed

Infantile spasms is an epileptic encephalopathy of early infancy with specific clinical and electroencephalographic (EEG) features, limited treatment options, and a poor prognosis. Efforts to develop improved treatment options have been hindered by the lack of experimental models in which to test prospective therapies. The neuropeptide adrenocorticotropic hormone (ACTH) is effective in many cases of infantile spasms, although its mechanism(s) of action is unknown. This review describes the emerging candidate mechanisms that can underlie the therapeutic effects of ACTH in infantile spasms. These mechanisms can ultimately help to improve understanding and treatment of the disease. An overview of current treatments of infantile spasms, novel conceptual and experimental approaches to infantile spasms treatment, and a perspective on remaining clinical challenges and current research questions are presented here. This summary derives from a meeting of specialists in infantile spasms clinical care and research held in New York City on June 14, 2010. PMID:21719797

Lymphoscintigraphy in malignant melanoma  

SciTech Connect

The development and rationale for the use of lymphoscintigraphy in the preoperative evaluation of patients with malignant melanoma being considered for elective lymph node dissection is reviewed. This overview is updated by an analysis of 135 patients with early stage malignant melanoma involving the head, neck, shoulders, and trunk at Moffitt Cancer Center and Research Institute at the University of South Florida (Tampa, FL). High discordancy rates (overall, 41%) were seen between drainage patterns predicted from historical anatomical guidelines and those revealed by the lymphoscintigraphic examination. The high discordancy rate was most pronounced in the head (64%) and the neck (73%). Surgical management was changed in 33% of the patients, overall. A preoperative lymphoscintigram is recommended for all patients with melanoma with head, neck, and truncal lesions evaluated for elective lymph node dissection as the lymphatic drainage patterns are often unpredictable and variable.

Microbiome and Malignancy

Current knowledge is insufficient to explain why only a proportion of individuals exposed to environmental carcinogens or carrying a genetic predisposition to cancer develop disease. Clearly, other factors must be important and one such element that has recently received attention is the human microbiome, the residential microbes including Bacteria, Archaea, Eukaryotes, and viruses that colonize humans. Here, we review principles and paradigms of microbiome-related malignancy, as illustrated by three specific microbial-host interactions. We review the effects of the microbiota on local and adjacent-neoplasia, present the estrobolome model of distant effects, and discuss the complex interactions with a latent virus leading to malignancy. These are separate facets of a complex biology interfacing all the microbial species we harbor from birth onward toward early reproductive success and eventual senescence.

[Malignant odontogenic tumors].  

PubMed

Malignant odontogenic tumors are extremely rare. As with benign odontogenic tumors, malignant epithelial odontogenic tumors or odontogenic carcinomas are distinguished from the even rarer mesenchymal ones, the odontogenic sarcomas. The existence of odontogenic carcinosarcomas is not yet acknowledged by the World Health Organization. Odontogenic carcinomas comprise ameloblastic carcinoma (AmCa), primary intraosseous carcinoma (PIOC), clear cell odontogenic carcinoma, odontogenic ghost cell carcinoma (OGCC), and the special case of metastasizing ameloblastoma. Odontogenic sarcomas consist of ameloblastic fibrosarcoma and ameloblastic fibrodentinosarcoma and fibroodontosarcoma. Whereas metastasizing ameloblastoma can be diagnosed only after having metastasized, all other malignant odontogenic tumors present with atypia, increased cellularity and mitoses, and invasion. Odontogenic sarcomas are regarded as low-grade tumors that rarely metastasize. Odontogenic carcinomas, however, especially AmCa, OGCC, and PIOC, are more aggressive, with a 5-year survival rate of about 70% for AmCa and OGCC and a 3-year survival rate of about 37% for PIOC. Radical surgery, eventually in combination with radiotherapy, is the treatment of choice. PMID:18392827

Asbestos-related malignancy  

SciTech Connect

Asbestos-associated malignancies have received significant attention in the lay and medical literature because of the increasing frequency of two asbestos-associated tumors, lung carcinoma and mesothelioma; the wide distribution of asbestos; its status as a prototype environmental carcinogen; and the many recent legal compensation proceedings, for which medical testimony has been required. The understanding of asbestos-associated carcinogenesis has increased through study of animal models, human epidemiology, and, recently, the application of modern molecular biological techniques. However, the detailed mechanisms of carcinogenesis remain unknown. A wide variety of malignancies have been associated with asbestos, although the strongest evidence for a causal association is confined to lung cancer and mesothelioma. Epidemiological studies have provided evidence that both the type of asbestos fiber and the industry in which the exposure occurs may affect the rates of asbestos-associated cancers. It has been shown that asbestos exerts a carcinogenic effect independent of exposure to cigarette smoking that, for lung cancers, is synergistically enhanced by smoking. Other questions remain controversial, such as whether pulmonary fibrosis necessarily precedes asbestos-associated lung cancer and whether some threshold level of exposure to asbestos (including low-dose exposures that may occur in asbestos-associated public buildings) may be safe. Mesothelioma, the most closely asbestos-associated malignancy, has a dismal natural history and has been highly resistant to therapy. However, investigational multi-modality therapy may offer benefit to some patients. 179 references.

Malignant mesothelioma in women.  

PubMed Central

BACKGROUND: Malignant mesothelioma reportedly shows different epidemiology and pathology in females, and a proportion are believed to arise spontaneously. METHODS: One hundred and seventy seven cases of malignant mesothelioma in females were reviewed, examined by histochemistry and immunohistochemistry, assessed for asbestosis and lung fibre burden by transmission electron microscopy with energy dispersive x ray analysis, and compared with 31 female controls. RESULTS: Two of one hundred and three cases tested for carcinoembryonic antigen were positive and were excluded from further analysis. Tumour cases showed increased amphibole burdens; in those in whom exposure information was known, 74 (80%) of 93 patients had a history of exposure to asbestos. Seventy two (47%) of 152 patients had lung fibrosis. Tumour site and histological type were little different from those reported in adult males. Mixed type histological pattern, lung fibrosis, and peritoneal site were associated with heavier lung asbestos burdens, but not exclusively. Thirty five (30%) of 117 patients had amphibole burdens of less than 2 x 10(6) fibres/g; the sites affected and the histological pattern of tumours in this group were similar to those in cases with amphibole fibre counts of > or = 2 x 10(6)/g lung. A higher lung amphibole burden than the mean burden in control females was found in 115 (98%) of 117 patients tested. CONCLUSIONS: The pathology of malignant mesothelioma appears to be similar in women and in men, and in cases associated and unassociated with asbestos.

Desmoplastic non-infantile ganglioglioma in late adulthood.

Desmoplastic infantile ganglioglioma (DIG) is an uncommon supratentorial neuroepithelial brain tumor that typically occurs in infants younger than 24 months. Desmoplastic non-infantile ganglioglioma (DNIG) is a rare variant of this intracranial neoplasm. There are only 16 DNIG cases reported in the literature, with all patients under the age of 25 at the time of presentation. These DIG and DNIG cases were radiologically and histologically similar, with good outcome after treatment. Despite the size and high mitotic index for patients with DNIG, the prognosis is generally favorable and gross total resection is sufficient. We present a case of a 59-year-old woman with a DNIG. To the best of our knowledge, this is the first case reported of DNIG in late adulthood. Clinical presentation, histological and radiological findings are discussed. PMID:20857318

[Malignant extraconal tumors of the orbit in childhood].  

PubMed

Malignant extraconal orbital tumors are very rare during childhood and must be referred as soon as possible to a highly specialized center to be managed by a multidisciplinary team. They are often referred on an emergency basis. Both diagnosis and treatment must be undertaken as soon as possible. The course of these malignant tumors can be acute and can jeopardize the function of the eye or be life-threatening, especially in the event of metastatic locations. Extra-axial proptosis is by far the most frequent revealing symptom. Local and general examinations are of utmost importance. Sometimes diagnosis should be clear with the association of an orbital tumor and deterioration of the general health status favoring metastatic disease. Most metastatic neuroblastomas present such clinical symptoms in young children. Today both CT and MRI are highly valuable in assessing the diagnosis and starting the management of these tumors. Biopsy is mandatory to confirm the diagnosis. It can be reinforced by molecular biology. Among the primitive tumors, soft tissue sarcomas, especially rhabdomyosarcomas, are the most frequent. The diagnosis is suggested when the onset of the disease is acute and the course is rapid. Most respond to neoadjuvant chemotherapy. In the event of a residual tumor, local treatment is indicated so that surgery and/or radiotherapy are used as second-line treatment. Prognosis is closely related to histology. It can be satisfactory (Langerhans' cell histiocytosis, lymphoma, meningioma, infantile fibrosarcoma) or poor (metastatic tumor, rhabdoid tumor). PMID:20303550

Linkage analysis of late-infantile neuronal ceroid-lipofuscinosis  

SciTech Connect

The neuronal ceroid-lipofuscinoses (NCL) are a group of neurodegenerative disorders with an autosomal-recessive pattern of inheritance. There are 3 main categories of childhood NCL, namely, infantile, late-infantile, and juvenile NCL. These can be distinguished on the basis of age of onset, clinical course, and histopathology. A number of variant forms of NCL have also been mapped to chromosome areas 1p32 and 16p12, respectively. The gene for late-infantile NCL (LINCL), CLN2, has been excluded from both these loci, but its location is as yet unknown. Recently, CLN5, the gene for the Finnish variant form of LINCL, was mapped to 13q21.1-32. Using the 3 microsatellite markers which were most tightly linked to CLN5, we have excluded CLN2 from this region using a subset of 17 families. Thus, CLN2 represents a fourth distinct genetic locus involved in the pathogenesis of NCL. 6 refs., 1 fig., 1 tab.

Solitary infantile myofibromatosis of the cranial vault: case report.  

PubMed

Infantile myofibromatosis is a mesenchymal disorder of early childhood characterized by the formation of tumors in the skin, muscle, viscera, bone, and subcutaneous tissue. Although relatively rare overall, it represents the most common fibrous tumor of infancy. The etiology of this disorder is unknown. Infantile myofibromatosis can present as a solitary or multicentric form. With the multicentric form, bone is often involved, but solitary bone lesions account for only 10% of the cases. Imaging findings are not pathognomonic, and the differential diagnosis usually includes eosinophilic granuloma (Langerhans cell histiocytosis), osteomyelitis, metastasis, osteoblastoma, epidermoid cyst, hemangioma, fibrous dysplasia, fibrosarcoma, and meningioma. A histological pattern is typical, but there are no histopathological differences between the solitary and multicentric forms. Solitary lesions generally have a favorable prognosis if totally removed, with a 10% recurrence rate; incompletely resected lesions recur. We report the case of a 9-year-old boy who came to our attention with a solitary infantile myofibroma of the calvarium, appearing as a tight-elastic, lightly tender mass in the left frontal area, eroding both the inner and the outer tables. Histopathologically, the specimens showed a spindle-cell tumor with dense reticulin fiber network and expression of smooth muscle actin. Fifty-eight months MR follow-up after total removal showed no residual or relapse. PMID:21279363

Recognition of the early signs and symptoms of malignant hyperthermia, and prompt treatment using dantrolene sodium require an increased index of suspicion and familiarity with this symptom complex, which has an increased incidence in children.

Propranolol is more effective than pulsed dye laser and cryosurgery for infantile hemangiomas.  

PubMed

Propranolol hydrochloride is a nonselective ?-blocker that is used for the treatment of hypertension, arrhythmia, and angina pectoris. In Japan, it was recently approved for the treatment of childhood arrhythmia. It has been observed to produce drastic involution of infantile hemangiomas. The aim of this prospective study was to examine propranolol's superiority to classical therapy with pulsed dye laser and/or cryosurgery in treating proliferating infantile hemangiomas. Fifteen patients between the ages of 1 and 4 months with proliferating infantile hemangiomas received grinded propranolol tablets 2 mg/kg per day divided in three doses. Twelve patients with proliferating infantile hemangiomas receiving pulsed dye laser and/or cryosurgery were enrolled as controls. Baseline electrocardiogram, echocardiogram, and chest x-ray were performed. Monitoring of heart rate, blood pressure, and blood glucose was performed every 2 weeks. Efficacy was assessed by performing blinded volume measurements and taking photographs at every visit. Propranolol induced significantly earlier involution and redness reduction of infantile hemangiomas, compared to pulsed dye laser and cryosurgery. Adverse effects such as hypoglycemia, hypotension, or bradycardia did not occur. Conclusion: The dramatic response of infantile hemangiomas to propranolol and few side effects suggest that early treatment of infantile hemangiomas could result in decreased disfigurement. Propranolol should be considered as a first-line treatment of infantile hemangiomas. PMID:23812512

The current evaluation and treatment of infantile spasms among members of the Child Neurology Society.  

PubMed

The optimal evaluation and treatment of children with infantile spasms is unknown. To aid in the development of a standardized approach to infantile spasms, members of the Child Neurology Society were surveyed to determine common practice. The survey had 222 responders with a responder rate of 18.5%. We found that the diagnostic evaluation and the use of first-line treatments varied among responders. For example, although adrenocorticotropic hormone continues to be the most commonly used first-line treatment for infantile spasms not due to tuberous sclerosis, some clinicians use corticosteroids, vigabatrin, and topiramate as first-line treatments for this group. Seventy percent of our responders reported seeing fewer than 10 new-onset cases of infantile spasms per year. Thus, future clinical trials will require multicenter collaboration. An important first step in such collaboration is to standardize the evaluation and treatment of infantile spasms within and between participating centers. PMID:22914371

Recessive mechanisms of malignancy.  

PubMed Central

It is increasingly recognised that recessive mutations play an important role in the pathogenesis of many forms of malignancy. Some of the affected loci may prove to be recessively-activated proto-oncogenes, but others are now known to be tumorigenic solely by virtue of their loss or inactivation and therefore form a distinct and novel family of tumour genes. Preliminary evidence suggests that such genes are likely to be functionally heterogeneous and to encode molecules involved in the inhibition of cellular proliferation and/or the induction of differentiation. Their further study is likely to illuminate fundamental mechanisms of normal cellular growth and differentiation as well as having important implications for the pathogenesis and management of cancer.

Helicobacter and Gastric Malignancies  

PubMed Central

Individuals infected with Helicobacter pylori, a stomach colonizing bacteria, have an increased risk of developing gastric malignancies. The risk for developing cancer relates to the physiologic and histologic changes that H. pylori infection induces in the stomach. In the last year numerous studies have been conducted in order to characterize the association between H. pylori infection and gastric cancer. These studies range from epidemiologic approaches aiming at the identification of environmental, host genetic, and bacterial factors associated with risk of gastric cancer, to molecular and cell biology approaches aiming at understanding the interaction between H. pylori and the transforming epithelial cell. In this review an account of the last year’s research activity on the relationship between H. pylori and gastric cancer will be given.

Temozolomide in malignant glioma  

PubMed Central

Glioblastoma multiforme WHO grade IV (GBM) is the most aggressive malignant glioma and the most frequent primary tumor of the central nervous system. The median survival of newly diagnosed GBM patients was between 9 to 12 months prior to treatment with temozolomide being introduced. Primary resection that is as complete as possible is recommended for malignant glioma. Conventional fractionated irradiation 55 to 60 gy with concomitant temozolomide followed by standard temozolomide 6 cycles (5/28) (EORTC/NCIC-regime published by R Stupp in 2005) is the standard of care for newly diagnosed GBM after surgery, independent of the methylation status of the MGM-T gene promoter. Age is no contraindication for treatment with temozolomide, although comorbidity and performance status have to be considered. For temozolomide naive GBM and astrocytoma grade III patients with disease progression, temozolomide is still the treatment of choice outside of clinical studies. A general consensus regarding the schedule of choice has not yet been achieved; so far the 5 out of 28 days regimen (5/28) is the standard of care in most countries. Patients with disease progression after standard temozolomide (5/28) are candidates for clinical studies. Outside of clinical studies, dose-dense (7/7), prolonged (21/28), or metronomic (28/28) temozolomide, or alternatively a nitrosourea-based regimen can be an option. The excellent toxicity profile of temozolomide allows for various combinations with antitumor agents. None of these combinations, however, have been demonstrated to be statistically significantly superior compared to temozolomide alone. The role of lower dosed, dose-dense, or continuous regimen with or without drug combination and the role of temozolomide for newly diagnosed astrocytoma grade III and low grade glioma still has to be determined.

Management of infantile hemangiomas : current and potential pharmacotherapeutic approaches.  

PubMed

Infantile hemangiomas (IH), benign vascular neoplasms, are the most common tumors of infancy and childhood. Most IH are medically insignificant; however, a proportion will require treatment because of interference with vital structures, threat of significant disfigurement, ulceration, or bleeding. This article reviews current and potential pharmacotherapeutic approaches to the treatment of IH. While corticosteroids have long been considered the mainstay of medical therapy for IH, several new treatments have recently emerged, the most promising of which is oral propranolol. Topical timolol and imiquimod are additional new therapies that may also prove to be effective, particularly for the treatment of superficial IH. PMID:23456550

Infantile hypertrophic pyloric stenosis: where should it be treated?  

PubMed Central

A retrospective analysis in the form of an audit into the management of infantile hypertrophic pyloric stenosis in a district general hospital has revealed that the results are equivalent to that of published data from specialised units. It is stressed in this study that close co-operation has to be maintained between paediatricians and surgeons in the care of these infants. The diagnosis can be made on clinical grounds in the majority of cases. The operation has to be carried out by experienced surgeons and anaesthetists. The morbidity can be minimised under these circumstances and pyloromyotomy can be performed safely in a district general hospital.

The immune complexes in infantile hydrocephalic CSF in Nigerian children using a laser nephelometer were quantified. The values obtained were relatively low when compared with the serum levels. There was no evidence of selective admixture or of a breakdown of blood-brain-barrier (BBB). The low levels of immune complexes, when associated with implantation of shunt device for treatment of the hydrocephalus, may be a predisposing factor that can lead to overwhelming infection among this group of patients in a developing country like Nigeria. Between the hydrocephalic fluid and lumbar CSF, an IgG gradient was found. PMID:3791284

Infantile spasms: a U.S. consensus report.

The diagnosis, evaluation, and management of infantile spasms (IS) continue to pose significant challenges to the treating physician. Although an evidence-based practice guideline with full literature review was published in 2004, diversity in IS evaluation and treatment remains and highlights the need for further consensus to optimize outcomes in IS. For this purpose, a working group committed to the diagnosis, treatment, and establishment of a continuum of care for patients with IS and their families—the Infantile Spasms Working Group (ISWG)—was convened. The ISWG participated in a workshop for which the key objectives were to review the state of our understanding of IS, assess the scientific evidence regarding efficacy of currently available therapeutic options, and arrive at a consensus on protocols for diagnostic workup and management of IS that can serve as a guide to help specialists and general pediatricians optimally manage infants with IS. The overall goal of the workshop was to improve IS outcomes by assisting treating physicians with early recognition and diagnosis of IS, initiation of short duration therapy with a first-line treatment, timely electroencephalography (EEG) evaluation of treatment to evaluate effectiveness, and, if indicated, prompt treatment modification. Differences of opinion among ISWG members occurred in areas where data were lacking; however, this article represents a consensus of the U.S. approach to the diagnostic evaluation and treatment of IS.

Corticosteroids for the treatment of infantile spasms: a systematic review.  

PubMed

Adrenocorticotropic hormone (ACTH) and corticosteroids are the usual first-line treatment options for infantile spasms. Despite significant differences, these agents are often lumped together in this context. There is a need to systematically explore the efficacy of corticosteroids in the treatment of infantile spasms, especially in comparison to ACTH. This review identified and analyzed corticosteroid clinical trials and summarized their short-term efficacy and tolerability. Primary outcome was cessation of spasms and abolition of hypsarrhythmia on prolonged video electroencephalographic monitoring. Eight corticosteroid clinical trials were found with only 2 fulfilling the criteria for adequate design. The weighted-mean efficacy of corticosteroids to achieve primary outcome was 31% for these 2 methodologically adequate studies. Including reanalyzed data from 3 other studies, the corticosteroid efficacy was found to be 42%. On the basis of the available evidence, the efficacy of high-dose corticosteroids is similar to low-dose ACTH and inferior to high-dose ACTH, the current standard treatment. PMID:22859699

The aim of this study was to evaluate the outcome of treating infantile hemangioma with the use of oral propranolol. A total of 27 patients with hemangiomas were treated with oral propranolol therapy. The subjects included 21 females and 6 males whose age ranged between 3 weeks and 7 months. Locations of lesions were as follows: 22 on the face and neck, 3 on the trunk, and 2 on the limbs. The dose of 0.5 mg/kg/d of propranolol was administered; and was gradually doubled to a maximum of 2 mg/kg/d. The treatment lasted for a period of 2.75 to 5.75 months without major complications. Two days later, a change in color was observed in 100% of patients, and 2 weeks later >75% reduction in diameter of the original lesion was found in 25.9% of patients. Treating infantile hemangioma with the use of oral propranolol is effective and reliable. PMID:21629056

Introduction Each year in the UK there are 8100 new cases of malignant melanoma, and 1800 deaths, largely as a result of metastatic disease. The median survival of people with metastatic melanoma is 6-9 months after diagnosis, with 10% of people alive at 5 years. Chemotherapy is given with palliative rather than curative intent for metastatic disease. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of chemotherapy for metastatic melanoma? What are the effects of immunotherapy for metastatic melanoma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 23 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: adding interferon alfa (with or without interleukin-2) to chemotherapy; dacarbazine; single-agent or combination chemotherapy; supportive palliative care alone or with chemotherapy; and temozolomide.

Catumaxomab: in malignant ascites.  

PubMed

Catumaxomab is a rat/murine hybrid, trifunctional, bispecific (anti-human epithelial cell adhesion molecule [EpCAM]?×?anti-CD3) monoclonal antibody. Compared with paracentesis alone, paracentesis followed by catumaxomab therapy was associated with significant prolongation of paracentesis-free survival and time to repeat paracentesis in a randomized, open-label, multicentre, pivotal phase II/III trial in patients with recurrent symptomatic malignant ascites due to EpCAM-positive tumours who were resistant to conventional chemotherapy. The benefits of catumaxomab were seen across a broad range of epithelial ovarian and nonovarian cancers, and irrespective of whether or not catumaxomab recipients developed human anti-mouse antibodies. Combining catumaxomab with paracentesis also resulted in more pronounced and prolonged reductions in ascites signs and symptoms and a delayed deterioration in health-related quality of life compared with paracentesis alone. Despite the study not being designed or powered to evaluate overall survival, significant differences favouring the addition of catumaxomab to paracentesis were seen in analyses of the safety population and the subpopulation of patients with gastric cancer. Catumaxomab was generally well tolerated in the pivotal phase II/III trial. The most frequent adverse events attributed to catumaxomab treatment included cytokine-release-related symptoms, which were mostly of mild to moderate severity and manageable with standard symptomatic treatment.

Pathogenesis of malignant mesothelioma.  

PubMed

Malignant mesothelioma (MM) is a very aggressive tumor that is caused by environmental, biologic, and genetic factors. Among these factors, asbestos plays a major role. The link between asbestos and MM has been firmly established through numerous epidemiologic studies conducted during the past 40 years. However, the causal role of chrysotile asbestos compared with crocidolite asbestos in MM, the method of correctly establishing asbestos exposure, the amount of asbestos necessary to cause MM, and the mechanisms of asbestos tumorigenicity are still being debated. Along with asbestos, Simian virus 40 (SV40), a DNA monkey virus, has recently been implicated in the etiology of MM. Simian virus 40 large T antigen (Tag) and small t antigen (tag) are largely responsible for the carcinogenicity of the virus, and it is possible that SV40 and asbestos are cocarcinogens. Finally, a genetic factor identified in 3 villages in Cappadocia, Turkey, where 50% of individuals die of MM, appears to be the cause of a high incidence of the disease. In these villages, genetic predisposition for MM works together with erionite, a nonasbestos fiber found in the stones used in construction of houses. The diagnosis of MM is made histologically and confirmed through electron microscopy and immunohistochemistry. Currently available therapies for MM prolong survival by a few months at most. An SV40 vaccine is being developed for human use and it is hoped that it may reduce the incidence of MM in asbestos workers. PMID:15117424

[Malignant pleural mesothelioma].  

PubMed

Malignant pleural mesothelioma continues to be a clinical challenge and its incidence will continue to increase worldwide. Once diagnosed with pleural mesothelioma, patients nearly invariably die of the disease. While the benefit of chemotherapy for advanced disease has been established, many other aspects of treatment continue to be controversial, in particular in regard to surgery and radiotherapy. However, the best survival data is reported from groups using multimodality treatment including surgery for patients qualifying from a tumor stage - and functional perspective. Therefore, efforts should focus on improving staging systems. Translational studies should be included with the final aim of finding reliable markers for response to therapy. Despite both, the increase in basic biologic knowledge and the fact that many new agents have reached various stages of development, the number of new treatments that have been approved for patients has not increased. As mesothelioma is a rare disease, the number of patients is limiting and more innovative trial designs (such as multi-arm multi-stage trials [1]) using cooperative platforms to eliminate less effective treatments may be the best way forward.

Ewing's Sarcoma and Second Malignancies  

PubMed Central

Ewing's sarcoma (ES) is a rare tumor that is most common in children and young adults. Late effects of ES therapy include second cancers, a tragic outcome for survivors of such a young age. This paper will explore the frequencies and types of malignancies that occur after ES. Additionally, it will review how second malignancies have changed with the shift in treatment from high-dose radiation to chemotherapy regimens including alkylators and epipodophyllotoxins. The risk of additional cancers in ES survivors will also be compared to survivors of other childhood cancers. Finally, the possible genetic contribution to ES and second malignancies will be discussed.

[Antihypertensive drugs and malignant neoplasia].  

PubMed

Analysis of epidemiological, cohort and randomized studies of antihypertensive drugs containing reports of development of malignant neoplasms shows that long term use of some antihypertensive drugs while preventing cardiovascular complications has been associated with increased risk of malignancies. Most convincing evidence exists for association between the use of diuretics and renal cancer. Association between the use of reserpine and breast cancer in women, between atenolol and some types of cancer in elderly men also can not be ruled out. There is no proof of existence of either negative or positive correlation between malignant neoplasia and long-term use of calcium antagonists, angiotensin converting enzyme inhibitors or angiotensin receptor blockers.

Effects of macrophage colony-stimulating factor on macrophages and their related cell populations in the osteopetrosis mouse defective in production of functional macrophage colony-stimulating factor protein.  

PubMed Central

The development of macrophage populations in osteopetrosis (op) mutant mice defective in production of functional macrophage colony-stimulating factor (M-CSF) and the response of these cell populations to exogenous M-CSF were used to classify macrophages into four groups: 1) monocytes, monocyte-derived macrophages, and osteoclasts, 2) MOMA-1-positive macrophages, 3) ER-TR9-positive macrophages, and 4) immature tissue macrophages. Monocytes, monocyte-derived macrophages, osteoclasts in bone, microglia in brain, synovial A cells, and MOMA-1- or ER-TR9-positive macrophages were deficient in op/op mice. The former three populations expanded to normal levels in op/op mice after daily M-CSF administration, indicating that they are developed and differentiated due to the effect of M-CSF supplied humorally. In contrast, the other cells did not respond or very slightly responded to M-CSF, and their development seems due to either M-CSF produced in situ or expression of receptor for M-CSF. Macrophages present in tissues of the mutant mice were immature and appear to be regulated by either granulocyte/macrophage colony-stimulating factor and/or interleukin-3 produced in situ or receptor expression. Northern blot analysis revealed different expressions of GM-CSF and IL-3 mRNA in various tissues of the op/op mice. However, granulocyte/macrophage colony-stimulating factor and interleukin-3 in serum were not detected by enzyme-linked immunosorbent assay. The immature macrophages differentiated and matured into resident macrophages after M-CSF administration, and some of these cells proliferated in response to M-CSF.

Case of infantile onset spinocerebellar ataxia type 5.  

PubMed

Dominant spinocerebellar ataxias are a rare clinically and genetically heterogeneous group of neurodegenerative disorders. They are characterized by progressive cerebellar ataxia resulting in unsteady gait, clumsiness, dysarthria, and swallowing difficulty. The onset of symptoms is usually in the third or fourth decade of life; however, more subtle clinical manifestations can start in early childhood. Spinocerebellar ataxia type 5, a dominant spinocerebellar ataxia associated with mutations involving ?-III spectrin (SPTBN2), has been described in 3 families. It typically consists of a slowly progressive spinocerebellar ataxia with onset in the third decade. The authors present the first case of infantile-onset spinocerebellar ataxia associated with a novel SPTBN2 mutation (transition C>T at nucleotide position 1438), the proband having a much more severe phenotype with global developmental delay, hypotonia, tremor, nystagmus, and facial myokymia.

Infantile bilateral glaucoma in a child with ectodermal dysplasia.  

PubMed

Ectodermal dysplasia is a rare disease which affects at least two ectodermal-derived structures such as hair, nails, skin, sweat glands and teeth. Approximately 200 different conditions have been classified as an ectodermal dysplasia and X-linked hypohidrotic ectodermal dysplasia (XHED) represents the commonest form. Clinically, XHED is characterized by hypotrichosis, hypohidrosis and hypodontia. A variety of ocular manifestations have been reported in XHED, the most common being dryness of eyes due to tear deficiency and instability of the film secondary to the absence of meibomian gland function. Here we report a child with the distinctive clinical features of XHED confirmed with molecular diagnosis who presented with infantile bilateral glaucoma, in addition to the classical ocular involvement in XHED.

Subdural Fluid Collections in Patients with Infantile Neuronal Ceroid Lipofuscinosis  

PubMed Central

Objective To describe subdural fluid collections on magnetic resonance imaging (MRI) as part of the natural history of infantile neuronal ceroid lipofuscinosis. Design Case series Setting Program on Developmental Endocrinology and Genetics, The Clinical Center, The National Institutes of Health, Bethesda, Maryland. Results During an ongoing bench-to-bedside clinical investigation, MRI examinations led to the incidental discovery of subdural fluid collections in four of nine patients with INCL. No particular event (such as trauma) or change in symptoms was linked to this finding, which was already in the chronic phase when discovered. Of the four patients, one was followed for 7 years, two for 4 years and a fourth patient was followed for 2.5 years. Over time, these collections remained stable or decreased in size. Conclusion Recognition that subdural fluid collections are part of the INCL disease process may obviate the necessity of additional workup as well as therapeutic interventions in these chronically sick children.

Comparison of infantile nystagmus syndrome in achiasmatic zebrafish and humans.  

PubMed

Infantile nystagmus syndrome (INS; formerly called congenital nystagmus) is an ocular motor disorder characterized by several typical nystagmus waveforms. To date, restrictions inherent to human research and the absence of a handy animal model have impeded efforts to identify the underlying mechanism of INS. Displaying INS-like spontaneous eye oscillations, achiasmatic zebrafish belladonna (bel) mutants may provide new insights into the mystery of INS. In this study, we demonstrate that these spontaneous eye oscillations match the diagnostic waveforms of INS. As a result, zebrafish bel mutants can be used as an animal model for the study of INS. In zebrafish bel mutants, visual pathway abnormalities may contribute to the spontaneous nystagmus via an inverted signal to the pretectal area. We hypothesized that human INS may also be linked to visual pathway abnormalities (possibly underdiagnosed in INS patients) in a similar way. PMID:21951006

Acute Infantile Encephalopathy Predominantly Affecting The Frontal Lobes (AIEF).  

PubMed

Acute Infantile Encephalopathy Predominantly Affecting the Frontal Lobes (AIEF) is a relatively recent described entity. This article includes case reports of two patients who had bifrontal involvement during acute febrile encephalopathy. Case 1 describes a 1-y-old boy who presented with hyperpyrexia and dialeptic seizures. Imaging revealed significant bilateral frontal lobe involvement while serology proved presence of Influenza B infection. Over a period of one wk, he recovered with significant cognitive decline and perseveratory behavior. Another 6-y-old boy presented with language and behavioral problems suggestive of frontal dysfunction after recovering from prolonged impairment of consciousness following a convulsive status epilepticus. Bilateral superior frontal lesions with gyral swelling was evident on neuroimaging. These cases are among the very few cases of AIEF described in recent literature and the article also reviews this unique subtype of acute encephalopathy. PMID:22183762

Advances in the adjuvant treatment of infantile fibrosarcoma.  

PubMed

Infantile fibrosarcoma is a rare soft tissue tumor, predominately affecting young infants. It grows rapidly and is locally infiltrative but rarely metastases. Complete surgical removal is usually curative but is impossible in some patients and would result in significant functional or cosmetic consequences in many others. Neoadjuvant chemotherapy will cause many tumors to shrink significantly, allowing less mutilating surgical resections to be performed--this is the current recommendation where immediate surgical removal cannot be accomplished without unacceptable morbidity. In contrast, there is no defined role for adjuvant chemotherapy or radiation following complete surgical resection. Although there is a significant risk of local recurrence, most of these can be successfully treated with further surgery and the overall survival rate exceeds 90%. PMID:12722878

Diagnostic dilemmas of infantile sarcoma of the forearm.  

PubMed

The authors present an interesting case of a suckling baby treated for forearm tumour. All the preoperative examinations including the imaging methods are documented, as are the surgical procedures and the final results. The case report is interesting not only because such surgery is infrequent but also due to the unpredictable progress of the final diagnosis statement. Before surgery the tumour was diagnosed as an organising haematoma; based on clinical and radiological signs the diagnosis subsequently rose to rapidly growing haemangioma or vascular malformation causing arm paresis and vascular supply disorder. The diagnosis was changed to angiolipoma during surgery. The final histopathological statement was: infantile fibrosarcoma. Despite the virtue of imaging methods and meticulous clinical examination, the surgical and histopathological findings are not necessarily absolutely identical. Having presented this particular case the authors would like to share their experience. PMID:21110498

Adult preferences for infantile facial features: an ethological approach.  

PubMed

In 1943 Konrad Lorenz postulated that certain infantile cues served as releasers for caretaking behaviour in human adults. This study is an attempt to confirm this hypothesis and to identify relevant cues. The stimuli studied were variations in facial features, and the responses were ratings of the attractiveness of the resultant infant faces. Parametric variations of eye height, eye width, eye height and width, iris size, and vertical variations in feature position (all presented in full-face drawings) were tested for their effect on the ratings, and highly significant preferences for particular stimuli were found. In general these preferences are consistent across a wide variety of environmental factors such as social class and experience with children. These findings are consistent with an ethological interpretation of the data. PMID:855947

Bone marrow transplantation for infantile ceramidase deficiency (Farber disease).  

PubMed

Infantile ceramidase deficiency (Farber disease) is an uncommon, progressive lysosomal storage disease characterized by multiple ceramide-containing nodules (lipogranulomata) in the subcutaneous tissue and upper aerodigestive tract, painful periarticular swelling, psychomotor retardation, and varying degrees of ocular, pulmonary or hepatic involvement. Management of Farber disease has been limited to symptomatic supportive care, and few affected infants survive beyond 5 years of age. We performed an allogeneic bone marrow transplant (BMT) from an HLA-identical heterozygous sister in a 9.5-month-old female with minimally symptomatic Farber disease who received a pre-transplant regimen of busulfan and cyclophosphamide. Ceramidase activity in peripheral blood leukocytes increased from 6% before transplant to 44% (donor heterozygote level) by 6 weeks after BMT. By 2 months after transplant, the patient's subcutaneous lipogranulomata, pain on joint motion, and hoarseness had resolved. Despite modest gains in cognitive and language development, hypotonia and delayed motor skills persisted. Gradual loss of circulating donor cells with autologous hematopoietic recovery occurred; VNTR analyses showed 50% donor DNA in peripheral blood cells at 8.5 months after BMT and only 1% at 21 months after transplant. Interestingly, leukocyte ceramidase activity consistently remained in the heterozygous range despite attrition of donor cells in peripheral blood. This novel observation indicates ongoing hydrolase production by non-circulating donor cells, possibly in the mononuclear phagocytic system, and uptake by recipient leukocytes. Although lipogranulomata and hoarseness did not recur, the patient's neurological and neurocognitive status progressively declined. She died 28 months after BMT (age 37.5 months) with pulmonary insufficiency caused by recurrent aspiration pneumonias. Allogeneic BMT improves the peripheral manifestations of infantile ceramidase deficiency, but may not prevent the progressive neurological deterioration, even when carried out in minimally symptomatic patients.

[Malignancies in patients on dialysis].  

PubMed

Incidence of malignancies in patients on dialysis is higher than in the comparable population. The topic is discussed from different points of view: A. Malignancy as a cause of renal failure (renal and urinary tract tumors, von Hippel-Lindau disease, Wilms tumor, multiple myeloma, tumors that compress urinary tract). B. Treatment of malignancies may result in renal failure and dialysis (nephrectomy, tumor-lysis syndrome, postradiation fibrosis, direct toxic effect of chemotherapy). C. Dialyzed patients are in higher risk of malignancies, especially those of the kidney and urinary tract but also of pharynx and larynx, thyroid gland etc. The following factors may play some roles: the basic disease, (e.g. analgesic and Balcan nephropathies, China Herba nephropathy etc.), changed metabolic milieu with retention of carcinogens, deficiency of selenium and other substances, acquired renal cysts, compromised immunity, decreased "wash-effect" in oligo-anuria and possible influence of dialysis itself (contact with phtalates, ethylenoxide, nitrosamines etc.). D. Special problems in diagnostics of malignancies. Controversial validity of s.c. "tumor markers" is mentioned. Among the causes of death in dialyzed patients cardiovascular and infectious diseases predominate. The active search for renal and urinary tract tumors should be performed. All other diagnostic procedures depend on the individual patient's risk profile. E. Methods of renal substitution are used in the treatment of malignancies (e.g. dialysis in the tumor-lysis syndrome, plasma filtration to remove paraproteins, intraperitoneal administration of chemotherapy similar to peritoneal dialysis approach). F. Malignant tumors and dialysis--some ethical problems. Withdrawal of dialysis in severely suffering patients should be approved by an informed patient and followed by maximal palliative therapy including palliative ultrafiltration if threat of lung edema occurs.

Effectiveness of Mentha piperita in the Treatment of Infantile Colic: A Crossover Study  

PubMed Central

Background. Infantile colic is a distressing and common condition for which there is no proven standard treatment. Objective. To compare the efficacy of Mentha piperita with simethicone in treatment for infantile colic. Methods. A double-blind crossover study was performed with 30 infants attending IMIP, Recife, Brazil. They were randomized to use Mentha piperita or simethicone in the treatment of infantile colic during 7 days with each drug. Primary outcomes were mother_s opinion about responses to the treatment, number of daily episodes of colic, and time spent crying, measured by a chronometer. Mann-Whitney and chi-square tests were used to compare the results. This study was previously approved by the Ethical Committee in Research at IMIP. Results. At baseline daily episodes of infantile colic was 3.9 (±1.1) and the mean crying time per day was 192 minutes (±51.6). At the end of the study daily episodes of colic fell to 1.6 (±0.6) and the crying duration decreased to 111 (±28) minutes. All mothers reported decrease of frequency and duration of the episodes of infantile colic and there were no differences between responses to Mentha piperita and simethicone. Conclusions. These findings suggest that Mentha piperita may be used to help control infantile colic. However, these results must be repeated by others studies.

Breast calcifications: which are malignant?  

PubMed

Most calcifications depicted on mammograms are benign. However, calcifications are important because they can be the first and earliest sign of malignancy. For detection and analysis of microcalcifications, high-quality images and magnification views are required. The American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) classifies calcifications on mammograms into three categories: typical benign, intermediate concern and higher probability of malignancy, according to types and distribution of calcifications. Benign calcifications are typically larger, coarser, round with smooth margins and have a scattered or diffuse distribution. Malignant calcifications are typically grouped or clustered, pleomorphic, fine and with linear branching. It is important for radiologists to detect, evaluate, classify and provide appropriate recommendations for calcifications perceived on mammograms to provide proper management. PMID:19787181

The use of cyclosporin is well established within the ophthalmology community, especially against sight threatening intraocular inflammation. It is well known however, that immunosuppression in general is a risk factor for the development of malignancy and numerous studies point to the risk imposed by cyclosporin. This article analyses and reviews all relevant studies with regard to the development of malignancy associated with the use of cyclosporin and extrapolates this into the ophthalmic setting. This is to enable clinicians to assess the risks in individual patients and to present a monitoring regime which can be used in patients undergoing cyclosporin treatment. The review is solely concerned with the risk of the development of malignancy following cyclosporin immunosuppression and not with any other adverse effect.

[The spleen in hematologic malignancies].  

PubMed

The spleen represents a major lymphatic and hematologic organ and, as such, is frequently involved in hematologic malignancies. Splenomegaly may constitute the first clinical sign leading to the diagnosis of a hematologic malignancy. Vice versa, the presence, or suspicion of a hematologic malignancy requires investigation of the spleen. In case of splenomegaly of unknown origin, directed history, clinical examination, and laboratory testing including a complete blood count with microscopic investigation of a peripheral blood smear, frequently allow to establish a tentative diagnosis. Whenever possible, further specific testing should be based on a thorough primary evaluation to avoid unnecessary diagnostic procedures. In light of the current diagnostic options, diagnostic splenectomy can usually be avoided to establish definitive diagnosis. Indolent lymphomas (chronic lymphocytic leukaemia, hairy cell leukaemia, splenic marginal zone lymphoma) and myeloproliferative neoplasms (chronic myeloid leukaemia, polycythemia vera, essential thrombocythemia, primary and secondary myelofibrosis) are the most prevalent hematologic malignancies associated with splenomegaly. Therapeutic options are highly differentiated depending on the underlying disease. Apart from very rare exceptions, therapeutic splenectomy can usually be avoided. PMID:23454563

Cutaneous Manifestations of Internal Malignancy  

PubMed Central

Background: Many malignancies affecting the internal organs display cutaneous manifestations which may be either specific (tumor metastases) or nonspecific lesions. Aims: The study is aimed at determining the frequency and significance of cutaneous manifestations among patients with internal malignancy. Materials and Methods: 750 cases of proven internal malignancy, who attended a cancer chemotherapy center in South India, were studied. Specific infiltrates were confirmed by histopathology, fine needle aspiration cytology (FNAC) and marker studies. Results: Out of the 750 patients with internal malignancy, skin changes were seen in a total of 52 (6.93%) patients. Conclusion: Cutaneous metastases (specific lesions) were seen in 20 patients (2.66%): contiguous in 6 (0.8%), and non-contiguous in 14 (1.86%). Nonspecific skin changes were seen in 32 patients (4.26%). None of our patients presented with more than one type of skin lesions. Herpes zoster was the most common nonspecific lesion noticed in our patients, followed by generalized pruritus, multiple eruptive seborrheic keratoses, bullous disorder, erythroderma, flushing, purpura, pyoderma gangrenosum, insect bite allergy and lichenoid dermatitis.

Predictive Characteristics of Malignant Pheochromocytoma  

PubMed Central

Purpose The prognosis of patients with malignant pheochromocytoma is poor, but the predictive factors are not well understood. We aimed to identify the clinical characteristics predictive of malignancy after initial surgical removal in patients with pheochromocytoma. Materials and Methods We retrospectively reviewed the records of 152 patients diagnosed with pheochromocytoma, including 5 (3.3%) with metastasis at the time of the initial surgical excision and 12 (7.9%) who developed metastasis during follow-up. To determine the factors predictive of malignancy, we compared clinical, radiographical, and urinary chemical findings between patients with benign and malignant disease. Mean follow-up was 41.5 months (range, 0.9-298 months) after surgery. Results Malignant tumors were significantly larger than benign tumors (11.1±4.0 cm vs. 6.2±3.4 cm, p<0.001), and postoperative persistence of arterial hypertension was more frequent after removal of malignant than benign tumors (p=0.001). Among the 147 patients without metastatic disease at diagnosis, those who developed metastasis had significantly lower concentrations of urinary catecholamine metabolites per unit of tumor, including vanillylmandelic acid (1.2 vs. 3.7 mg/day/cm, p=0.049), epinephrine (4.5 vs. 168.9 µg/day/cm, p=0.008), and norepinephrine (13.1 vs. 121.8 mg/day/cm, p<0.001). The overall 5-year metastasis-free survival rate was 84.4% and was significantly higher in patients with smaller tumors (?5.5 vs. >5.5 cm; 90.6% vs. 81.2%, p=0.025) and higher 24-hour secretion of vanillylmandelic acid (>2.1 vs. ?2.1 mg/day/cm; 94.9% vs. 70.9%, p=0.019). Conclusions Large tumor size (>5.5 cm) and minimally elevated 24-hour urinary vanillylmandelic acid (?2.1 mg/day/cm) were significantly associated with a higher probability of a malignant pheochromocytoma portending a lower metastasis-free survival and mandating more rigorous follow-up after surgery.

Animal models of malignant mesothelioma.  

PubMed

Animal models of diffuse malignant mesothelioma have historically been used to assess carcinogenicity of various fiber types and to study the pathogenesis of this unusual neoplasm. Pleural and peritoneal mesotheliomas have been induced in rodents following exposure to erionite or asbestos fibers, radionuclides, particulate nickel compounds, and chemicals such as 3-methylcholanthrene. The role of SV40 virus as a cofactor with asbestos fibers in the development of diffuse malignant mesotheliomas in humans has been explored in animal models. SV40 virus alone induces mesotheliomas in hamsters. Generation of new transgenic mouse strains with targeted expression of SV40 large T and small t antigens in the mesothelium would be very useful for mechanistic studies. Human malignant mesotheliomas frequently show hypermethylation or deletions at the Cdkn2a/Arf and Cdkn2b gene loci and deletions or mutations at the NF2 gene locus. Heterozygous Nf2 (+/-) mice exposed to crocidolite asbestos fibers exhibited accelerated development of malignant mesotheliomas compared to wild-type littermates. Loss of the wild-type Nf2 allele, leading to biallelic inactivation, was observed in nine mesothelioma cell lines derived from Nf2 (+/-) mice. Similar to human malignant mesotheliomas, tumors from Nf2 (+/-) mice showed frequent homozygous deletions of the Cdkn2a/Arf locus and adjacent Cdkn2b tumor suppressor gene. As in the human disease, murine mesotheliomas also showed constitutive activation of Akt. This murine model of asbestos carcinogenesis recapitulates the molecular and histopathological features of the human disease and has significant implications for preclinical testing of novel preventive or therapeutic modalities.

YouTube videos as a teaching tool and patient resource for infantile spasms.  

PubMed

The purpose of this study was to assess YouTube videos for their efficacy as a patient resource for infantile spasms. Videos were searched using the terms infantile spasm, spasm, epileptic spasm, and West syndrome. The top 25 videos under each term were selected according to set criteria. Technical quality, diagnosis of infantile spasms, and suitability as a teaching resource were assessed by 2 neurologists using the Medical Video Rating Scale. There were 5858 videos found. Of the 100 top videos, 46% did not meet selection criteria. Mean rating for technical quality was 4.0 of 5 for rater 1 and 3.9 of 5 for rater 2. Raters found 60% and 64% of videos to accurately portray infantile spasms, respectively, with significant agreement (Cohen ? coefficient = 0.75, P < .001). Ten videos were considered excellent examples (grading of 5 of 5) by at least 1 rater. YouTube may be used as an excellent patient resource for infantile spasms if guided search practices are followed. PMID:21551373

Information on Infantile Colic on the World Wide Web.  

PubMed

INTRODUCTION: The purpose of this study was to explore and describe the type and quality of information on infantile colic that a parent might access on the World Wide Web. METHODS: Two checklists were used to evaluate the quality indicators of 24 Web sites and the colic-specific content. RESULTS: Fifteen health information Web sites met more of the quality parameters than the nine commercial sites. Eight Web sites included information about colic and infant abuse, with six being health information sites. DISCUSSION: The colic-specific content on 24 Web sites reflected current issues and controversies; however, the completeness of the information in light of current evidence varied among the Web sites. Strategies to avoid complications of parental stress or infant abuse were not commonly found on the Web sites. Pediatric professionals must guide parents to reliable colic resources that also include emotional support and understanding of infant crying. A best evidence guideline for the United States would eliminate confusion and uncertainty about which colic therapies are safe and effective for parents and professionals. PMID:22664097

Infantile systemic hyalinosis: a case report with a novel mutation.  

PubMed

Infantile Systemic Hyalinosis (ISH) (OMIM 236490) is a rare, progressive and fatal autosomal recessive disorder characterized by multiple subcutaneous skin nodules, gingival hypertrophy, osteopenia, joint contractures, failure to thrive, diarrhea with protein losing enteropathy, and frequent infections. There is diffuse deposition of hyaline material in the skin, gastrointestinal tract, muscle and endocrine glands. It is caused by mutations in the ANTXR2 (also known as CMG2) gene, which encodes a trans-membranous protein involved in endothelial development and basement membrane-extracellular matrix assembly. We describe a child with classical features of ISH presenting in infancy with severe chronic debilitating pain and progressive joint contractures. The diagnosis was confirmed by molecular DNA sequencing of ANTXR2 gene which revealed a novel homozygous mutation not previously reported; 79 bp deletion of the entire exon 11 (c.867_945del, p.E289DfsX22). Although this is the first reported case of ISH in Oman, we believe that the disease is under-diagnosed since children affected with this lethal disease pass away early in infancy prior to establishing a final diagnosis.

Endoscopic goniotomy: a potential surgical procedure for primary infantile glaucoma  

NASA Astrophysics Data System (ADS)

Goniotomy is an effective treatment for primary infantile glaucoma. Unlike trabeculotomy, goniotomy facilitates the visualization of the trabecular meshwork and does not disturb the conjunctiva. Because a cloudy cornea may prevent a clear view of the anterior chamber angle through the operating microscope, we investigated whether an endoscope would improve visualization during goniotomy in pig cadaver eyes. We deepened the anterior chamber of each pig eye with viscoelastic material. A modified 23-gauge needle attached to an Olympus 0.8 mm diameter flexible fiberoptic endoscope entered the anterior chamber through a 3 mm limbal incision. The angle was clearly seen on a videoscreen as the needle approached and incised the trabecular pillars for 120 degree(s); the iris immediately fell back. Following the procedure, the eyes were fixed in formalin and sectioned for light microscopy, or fixed in 2% glutaraldehyde for scanning electron microscopy. Trabecular pillars were present from the iris root to Schwalbe's line in the untreated region of the anterior chamber angle. The treated area demonstrated incision of the trabecular pillars with opening of the underlying trabecular meshwork.

Intravenous pamidronate in the treatment of severe idiopathic infantile hypercalcemia.  

PubMed

Idiopathic infantile hypercalcemia (IIH) is a rare disorder caused by CYP24A1 loss-of-function mutation, resulting in impaired degradation of 1,25-dihydroxyvitamin D3. Pamidronate, an intravenously administered bisphosphonate, which is a potent inhibitor of bone resorption, has been reported only once for treatment IIH. We present a case of a previously healthy 5-month-old boy with IIH, where calcemia peaked to 5 mmol/L. Treatment with methylprednisone and furosemide had only minor effects; therefore, 2 intravenous infusions of pamidronate (0.6 mg/kg per dose) corrected the serum calcium level to 2.95 mmol/L. Furthermore, CYP24A1 homozygous mutation p.R396W (c.1186c>t) was identified in this patient, confirming the clinical diagnosis of IIH. In conclusion, IIH has a favorable outcome once properly detected and appropriately treated. Pamidronate has a beneficial effect in those patients with IIH where glucocorticoids and furosemide fail to meet the expectations.   PMID:23485543

VECP evidence for binocular function in infantile esotropia.  

PubMed

Since commonly used clinical methods of measuring binocular function require subjective responses, this testing has been limited to more cooperative children, usually older than 2 years of age. Recently, we have begun using a clinically practical, visually evoked cortical potential (VECP) method to detect the presence of binocular neurons in infants and young children. We studied 14 children, ages 4 to 44 months, with infantile esotropia. Nine had surgical correction for esotropia by the age of 2 years. Twenty-five normal infants ages 6 weeks to 22 months served as controls. Most normal infants showed the development of the "beat" by 2 months of age. The "sum" VECP was not consistently present until age 6 months. Four of the five esotropic infants less than 1 year of age, demonstrated neither a "sum" nor "beat" response. All nine patients with corrective surgery performed before 2 years of age developed a significant sum response and three developed a beat. Five patients had not had surgery until after 2 years of age. Two developed a sum and one a beat, but none had both beat and sum responses. The results suggest that there is a loss of nonlinear binocular response in esotropic children not corrected before the age of 2 years and that these responses can be restored after early treatment even if not present at the time of surgery.

[Congenital solitary infantile myofibroma: report of two cases].  

PubMed

The infantile myofibromatosis is a rare pathology usually affecting children under 2 years. More than half are congenital, located in head and neck in a 30% of the cases. Myofibroma is a benign mesenchymal tumor that appear an isolated lesion or multiple, with or without visceral involvement. Case 1: A newborn girl that presents lump in scalp suspected of encefalocele. Ultrasound and RM: solid and heterogeneous mass 4 x 2 cm with increased peripheral vascularisation. Case 2: A 7-month-old baby boy with lump in right occipital zone detected at 4 months. Ultrasound and RM: injury 1 x 1.5 cm in head esplenio muscle suggestive of hemangioma. Results: After surgical total resection, the histological study and immunohistochemical identified the lesion as myofibroma. The evaluation of disease dissemination was normal and the recovery of the patients was favorable. The differential diagnosis of myofibroma must be carried out with other mesenchymal tumors and with non neoplastic injuries characteristics of the region affects. The visceral location and multiple forms worsen the prognosis, so is important do an exhaustive study. Treatment is conservative surgery, but if there is no risk to the child, the possibility of spontaneous regression makes the abstention therapeutic a correct alternative. PMID:22295664

A Recurrent PDGFRB Mutation Causes Familial Infantile Myofibromatosis.  

PubMed

Infantile myofibromatosis (IM) is the most common benign fibrous tumor of soft tissues affecting young children. By using whole-exome sequencing, RNA sequencing, and targeted sequencing, we investigated germline and tumor DNA in individuals from four distinct families with the familial form of IM and in five simplex IM cases with no previous family history of this disease. We identified a germline mutation c.1681C>T (p.Arg561Cys) in platelet-derived growth factor receptor ? (PDGFRB) in all 11 affected individuals with familial IM, although none of the five individuals with nonfamilial IM had mutations in this gene. We further identified a second heterozygous mutation in PDGFRB in two myofibromas from one of the affected familial cases, indicative of a potential second hit in this gene in the tumor. PDGFR-? promotes growth of mesenchymal cells, including blood vessels and smooth muscles, which are affected in IM. Our findings indicate p.Arg561Cys substitution in PDGFR-? as a cause of the dominant form of this disease. They provide a rationale for further investigations of this specific mutation and gene to assess the benefits of targeted therapies against PDGFR-? in aggressive life-threatening familial forms of the disease.

Food allergy testing in infantile eczema: a clinical approach and algorithm.  

PubMed

The complex relationship between food allergy and infantile eczema has prompted divergent approaches to investigating potential food triggers in eczematous patients. It is well recognised that a significant proportion of infants with eczema have immunoglobulin E-mediated food allergy, reported to range between 20-80%. Determining whether certain foods trigger an eczematous flare in individual infants with eczema is difficult. For all infants with eczema, good skin care is the mainstay of treatment but identifying and avoiding triggers (both allergic and non-allergic) is important in some infants. Given this, we have a developed an algorithm that can be used by dermatologists in the investigation and management of food allergies in infantile eczema. Issues such as patient selection, investigation and elimination diets are addressed, with reference to relevant evidence in the literature. Our aim is to provide dermatologists with a framework to manage food allergies in infantile eczema, allowing the problem to be addressed with confidence. PMID:22686941

Multimodality imaging of malignant pheochromocytoma.  

PubMed

Pheochromocytomas offer the opportunity to explore multiple pathophysiological mechanisms through functional imaging. MIBG scintigraphy and PET scanning with tracers of the sympathetic nervous system are based on uptake of catecholamines and catecholamine-like compounds by hNET, the human norepinephrine transporter. In-111 pentetreotide scanning involves the imaging of somatostatin receptors on the cellular surface of tissues. FDG PET scanning examines the transport and incorporation of FDG into cells. We present a patient with malignant pheochromocytoma who underwent multitracer imaging to characterize the tumor and probe its pathophysiology to direct a therapeutic approach. This case underscores the inherent difficulties in the diagnosis and localization of malignant pheochromocytomas. Multiple approaches to functional and anatomic imaging may be required to fully delineate the extent of disease and similarly to direct radionuclide-based therapy. PMID:17117086

Height at diagnosis of malignancies.  

PubMed Central

Studies of the presenting height of children with malignancies have produced conflicting results, from an excess of taller patients to an excess of shorter patients. The problems of measurement bias, inadequate comparison populations, small numbers of patients, subgroup analyses, and overreliance on simple significance tests are all possible reasons for the variation in results. To clarify this issue, we studied heights at diagnosis of 3657 children and adolescents aged under 18 years. Their malignancies included acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin's disease, acute non-lymphoblastic leukaemia, osteosarcoma, retinoblastoma, neuroblastoma, Wilms' tumour, rhabdomyosarcoma, and Ewing's sarcoma. Compared with published standards for the heights of children in control populations, no significant deviation from population norms was found for patients in any of the 10 disease categories after proper adjustment for multiple significance testing.

Vulvar Malignancy in Neurofibromatosis Syndrome  

PubMed Central

Type 1 neurofibromatosis (NF1) is a dominantly inherited neurologic disorder that affects primarily the skin, bones, and peripheral nervous system. It may be associated with a variety of clinical manifestations including cafe-au-lait spots, skinfold freckling, Lisch nodules, and visceral neurofibromas. Individuals affected by NF1 harbor an increased risk for both benign and malignant tumors. Malignant transformation is usually observed in the form of neurosarcoma. Rarely, NF1 affects the genital tract, and isolated vulvar localization is extremely rare. Here is reported a rare case of a solitary neurosarcoma of the vulva in a 43-year-old woman affected by NF1 syndrome treated with surgical excision. The purpose of this case is to underline the possibility of association between NF1 and genital tract sarcoma and to suggest an accurate evaluation of rapid growth vulvar mass in this setting.

Venous thromboembolism in malignant gliomas  

PubMed Central

Summary Malignant gliomas are associated with a very high risk of venous thromboembolism (VTE). While many clinical risk factors have previously been described in brain tumor patients, the risk of VTE associated with newer anti-angiogenic therapies such as bevacizumab in these patients remains unclear. When VTE occurs in this patient population, concern regarding the potential for intracranial hemorrhage complicates management decisions regarding anticoagulation, and these patients have a worse prognosis than their VTE-free counterparts. Risk stratification models identifying patients at high risk of developing VTE along with predictive plasma biomarkers may guide the selection of eligible patients for primary prevention with pharmacologic thromboprophylaxis. Recent studies exploring disordered coagulation, such as increased expression of tissue factor (TF), and tumorigenic molecular signaling may help to explain the increased risk of VTE in patients with malignant gliomas.

Melanocyte development and malignant melanoma.  

PubMed

Malignant melanoma is a notoriously aggressive disease that can affect relatively young individuals and whose incidence is rising at an alarming rate. Unlike many cancers, metastatic melanoma is poorly responsive to current therapies and mutations affecting p53, the retinoblastoma gene product or Ras which occur frequently in many other cancer types, appear to be rare or at least relatively late events in the progression of the disease. Recent advances in our understanding of the disease at the molecular level have indicated that in addition to the loss of cell cycle checkpoints which may be common to all cancers, malignant melanoma shares many characteristics in common with developmental precursors to melanocytes, the mature pigment producing cells of the skin and hair follicles which are responsible for skin and hair colour. This review therefore focuses on the signalling pathways that play a crucial role in the development of the melanocyte lineage which are subject to deregulation in malignant melanoma namely signalling by receptor tyrosine kinases, the Wnt signalling pathway, as well as loss of the p16INK4a cyclin-dependent kinase inhibitor. Intriguingly all three pathways impact on the expression or function of the microphthalmia-associated transcription factor which plays an essential role in melanocyte development. PMID:11007928

Immunotherapy of malignant brain tumors  

PubMed Central

Summary Despite aggressive multi-modality therapy including surgery, radiation, and chemotherapy, the prognosis for patients with malignant primary brain tumors remains very poor. Moreover, the non-specific nature of conventional therapy for brain tumors often results in incapacitating damage to surrounding normal brain and systemic tissues. Thus, there is an urgent need for the development of therapeutic strategies that precisely target tumor cells while minimizing collateral damage to neighboring eloquent cerebral cortex. The rationale for using the immune system to target brain tumors is based on the premise that the inherent specificity of immunologic reactivity could meet the clear need for more specific and precise therapy. The success of this modality is dependent on our ability to understand the mechanisms of immune regulation within the central nervous system (CNS), as well as counter the broad defects in host cell-mediated immunity that malignant gliomas are known to elicit. Recent advances in our understanding of tumor-induced and host-mediated immunosuppressive mechanisms, the development of effective strategies to combat these suppressive effects, and a better understanding of how to deliver immunologic effector molecules more efficiently to CNS tumors have all facilitated significant progress toward the realization of true clinical benefit from immunotherapeutic treatment of malignant gliomas.

Systemic amyloidosis and malignant disease  

PubMed Central

Among 8,758 necropsies there are 93 cases of systemic amyloidosis. Of these, 14 are associated with malignancy: seven with myelomatosis or malignant lymphoma, and seven with carcinoma. The incidence of amyloidosis in myelomatosis is at least 10%. Attention is drawn to the presence of amyloid in the tubular casts of `myeloma kidney'. In Hodgkin's disease the incidence is about 4% but it may be higher in patients receiving chemotherapy. In lymphosarcoma it is of the order of a fraction of 1% but in macroglobulinaemia, essential or associated with malignant lymphoma, the incidence is considerably higher. Systemic amyloid is found in one in 375 of patients with carcinoma and in only a single patient among 1,500 `control cases'. Renal carcinoma accounts for one-quarter of all carcinomas associated with systemic amyloid. The other carcinomas originate in a variety of organs. In myelomatosis, amyloid may be found in the tumour deposits. In Hodgkin's disease and in lymphosarcoma there appears to be greater amyloid deposition in neoplastic tissue than hitherto realized. The carcinomas provide a striking example of topographical association of amyloid and tumour, the two being closely related in six of seven cases. Images

Recurrent malignant salivary gland neoplasms.  

PubMed

Recurrent salivary gland malignancies present difficult therapeutic decisions and poor prognosis in many instances, and treatment becomes of a palliative nature only. As many of the salivary gland malignancies we see are of the recurrent type, the following study was done to determine the efficacy of a vigorous attempt at retreatment. During the period January 1, 1960, through December 31, 1984, 352 patients with major and minor salivary gland tumors were evaluated at our institution. There were 149 benign lesions and 203 patients with malignant tumors. Of these, 99 patients had recurrent and metastatic tumors that had been treated initially elsewhere. Thirty-three of these patients were able to be treated with curative intent: surgery, 21; surgery plus radiation, 9; radiation therapy alone, 2; and radiation plus chemotherapy, 1. The 5 year survival with no evidence of disease was achieved in three patients with surgery alone and two patients with surgery plus radiation therapy. The group of five patients was comprised of two patients with adenoid cystic carcinomas of the parotid, one with intermediate grade mucoepidermoid carcinoma of the parotid, one, sebaceous cell carcinoma of the parotid, and one, adenoid cystic carcinoma of an accessory salivary gland. The results of this study serve to re-emphasize the relative poor yield of attempts at retreatment of loco-regional recurrence of salivary gland tumors. PMID:2796352

Targeting hedgehog in hematologic malignancy.  

PubMed

The Hedgehog pathway is a critical mediator of embryonic patterning and organ development, including hematopoiesis. It influences stem cell fate, differentiation, proliferation, and apoptosis in responsive tissues. In adult organisms, hedgehog pathway activity is required for aspects of tissue maintenance and regeneration; however, there is increasing awareness that abnormal hedgehog signaling is associated with malignancy. Hedgehog signaling is critical for early hematopoietic development, but there is controversy over its role in normal hematopoiesis in adult organisms where it may be dispensable. Conversely, hedgehog signaling appears to be an important survival and proliferation signal for a spectrum of hematologic malignancies. Furthermore, hedgehog signaling may be critical for the maintenance and expansion of leukemic stem cells and therefore provides a possible mechanism to selectively target these primitive cell subpopulations, which are resistant to conventional chemotherapy. Indeed, phase 1 clinical trials of hedgehog pathway inhibitors are currently underway to test this hypothesis in myeloid leukemias. This review covers: (1) the hedgehog pathway and its role in normal and malignant hematopoiesis, (2) the recent development of clinical grade small molecule inhibitors of the pathway, and (3) the potential utility of hedgehog pathway inhibition as a therapeutic strategy in hemato-oncology.

The Problem of Atypical Neuroleptic Malignant Syndrome  

PubMed Central

Neuroleptic malignant syndrome is a serious and potentially fatal adverse effect of antipsychotic medications. Although diagnostic criteria for neuroleptic malignant syndrome have been established and are widely accepted and used, it should be recognized that atypical presentations occur, particularly during treatment with atypical antipsychotics. However, it remains unclear whether these atypical presentations represent early or impending neuroleptic malignant syndrome. Furthermore, since neuroleptic malignant syndrome is a diagnosis of exclusion, careful consideration of other neuropsychiatric conditions should occur. Relying on creatine phosphokinase elevation may result in an incorrect diagnosis of atypical neuroleptic malignant syndrome. We wish to present a case of this diagnostic dilemma in a patient with catatonia.

Sequential sup 123 I-IMP-SPECT in acute infantile hemiplegia  

SciTech Connect

Sequential {sup 123}I-N-isopropyl-p-iodoamphetamine (IMP) single-photon emission computed tomography (SPECT) was performed in 2 patients with acute infantile hemiplegia. In both patients, low uptake of IMP was detected in the targeted abnormal hemisphere. The {sup 123}I-IMP-SPECT findings indicative of a pathologic condition persisted even when the clinical findings and electroencephalographic abnormalities improved. Because of its sensitivity, noninvasiveness, and accurate reflection of the cerebral blood flow distribution, {sup 123}I-IMP-SPECT is useful in the examination of acute infantile hemiplegia and in the evaluation of prognosis.

A comparative study of genetic and neurobiological findings in disintegrative psychosis and infantile autism.

Although disintegrative psychosis (DP) was first described in 1908, the validity of the syndrome has not yet been fully documented. To investigate the validity of DP as defined in ICD-9, 13 cases of DP were compared with 39 cases of infantile autism with reference to lifetime parental psychopathology, neuroradiological findings and genetic abnormalities. The groups were matched for gender, age, intellectual level and social class. Apart from a significantly higher rate of electroencephalogram abnormalities in the disintegrative group there was very little in the neurobiological background to support a clear distinction between DP and infantile autism.

Infantile infection and diabetes insipidus in children with optic nerve hypoplasia  

PubMed Central

Background: Bilateral optic nerve hypoplasia (BONH) is often associated with other central nervous system midline abnormalities (septo-optic dysplasia). Hormonal dysfunction, caused by anterior (cortisol) and posterior (ADH) pituitary involvement, can be sudden, severe, and life threatening. Methods: Case series. Three cases of septo-optic dysplasia (SOD) presenting as infantile infection with associated diabetes insipidus are reported. The diagnosis of SOD was suspected only after ophthalmological evaluation; further evaluation led to the diagnosis of panhypopituitarism. Conclusions: A high index of suspicion is required to diagnose SOD in children when the disorder presents with infantile infection and hypernatraemia. Early warning signs of neonatal jaundice and hypoglycaemia should prompt ophthalmological evaluation.

PubMed Central

Congenital infantile fibrosarcoma (CIF) is a rare soft-tissue tumor in the pediatric age group and seldom involves the gastrointestinal tract. A 2-day-old boy was transferred to our hospital with a pneumpoperitoneum. After emergency operation, we could find a solid mass wrapping around a sigmoid colon and performed a segmental resection of sigmoid colon including a mass. Histopathologic examination showed an infantile fibrosarcoma origining from the muscular layer of colon. The baby was discharged on the 17th hospital day and followed for 1 yr without recurrence.

Fatal infantile neuromuscular presentation of glycogen storage disease type IV.  

PubMed

Glycogen storage disease type IV or Andersen disease is an autosomal recessive disorder due to deficiency of glycogen branching enzyme. Typically, glycogen storage disease type IV presents with rapidly progressive liver cirrhosis and death in childhood. Variants include a cardiopathic form of childhood, a relatively benign myopathic form of young adults, and a late-onset neurodegenerative disorder (adult polyglucosan body disease). A severe neuromuscular variant resembling Werdnig-Hoffmann disease has also been described in two patients. The objective was to describe two additional infants with the neuromuscular variant and novel mutations in the GBE1 gene. Branching enzyme assay, Western blot, RT-PCR and sequencing were performed in muscle biopsies from both patients. The cDNA of patient 1 was subcloned and sequenced to define the mutations. Muscle biopsies showed accumulation of periodic acid Schiff-positive, diastase-resistant storage material in both patients and increased lysosomal enzyme activity in patient 1. Branching enzyme activity in muscle was negligible in both patients, and Western blot showed decreased branching enzyme protein. Patient 1 had two single base pair deletions, one in exon 10 (1238delT) and the other in exon 12 (1467delC), and each parent was heterozygous for one of the deletions. Patient 2 had a large homozygous deletion that spanned 627 bp and included exons 8-12. Patient 1, who died at 41 days, had neurophysiological and neuropathological features of Spinal Muscular Atrophy. Patient 2, who died at 5(1/2) weeks, had a predominantly myopathic process. The infantile neuromuscular form of glycogen storage disease type IV is considered extremely rare, but our encountering two patients in close succession suggests that the disease may be underdiagnosed.

Infantile immunoglobulin A nephropathy showing features of membranoproliferative glomerulonephritis.  

PubMed

Immunoglobulin A nephropathy (IgAN) showing predominant IgA and complement 3 (C3) deposition on the mesangium is an immune complex-mediated glomerulonephritis. This renal disease is the most common primary glomerular disease worldwide. However, infantile onset of IgAN is rare. In the present patient, urinary protein and occult blood were detected in a girl aged 1 year and 8 months on urinalysis at a nursery school. Despite being young, a kidney biopsy was performed for diagnosis and the correct choice of therapy. Glomerular mesangial cell proliferation and a double contour of the glomerular basement membrane (GBM) resembling a railroad track were noted on light microscopy. Therefore, the patient was diagnosed morphologically with membranoproliferative glomerulonephritis (MPGN), because mesangial hypercellularity and thickening of the GBM were identified. However, on immunofluorescent staining, the deposition of immune complexes mainly consisting of IgA, IgG, and C3 was noted in the mesangial region and glomerular capillary loops. On electron microscopy, electron-dense deposits were recognized in the subendothelial and paramesangial regions associated with mesangial cell interposition into the subendothelial space. Autoimmune diseases and infection-associated secondary glomerulonephritis were clinically excluded, because there were no relevant signs or symptoms. Steroid treatment was initiated and findings of urinalysis were normalized within 8 months. This patient was finally diagnosed with IgA nephropathy showing the features of MPGN. The present patient was the youngest among reported cases of IgA nephropathy, suggesting that early onset of IgAN is associated with an MPGN-like lesion. The present report provides information for pathogenesis of IgA nephropathy. PMID:23089637

Second Malignancies Among Elderly Survivors of Cancer  

PubMed Central

The U.S. population is aging, life expectancy is increasing, and cancer is a disease associated with aging. Advances in screening and therapeutics have led to a growing number of cancer survivors who are at risk for the development of secondary malignancies. Although the risks for the development of second malignancies following a first diagnosis of cancer are well described for survivors of childhood malignancies, there are fewer data for malignancies common in older adults. With the aging of the U.S. population, and with improving survival statistics in many adult malignancies, there is an increasing need to identify those second malignancies that might develop in the older adult survivor of cancer. In this paper, we describe the types and rates of second malignancies following cancers commonly seen in older adults and review the literature on these malignancies. Comparisons are made between older and younger adults with regard to the risks for developing treatment-related cancers with different modalities. Recommendations for early detection of second malignancies are summarized, though there remains an unmet need for evidence-based guidelines for screening for second malignancies in the older adult in particular.

Although priapism secondary to hematologic malignancies has been well described, review of the literature reveals 75 case reports of priapism due to local corporeal involvement by solid tumors. Our recent experience with 6 cases of local invasion of the corporeal bodies is reviewed. Three transitional cell carcinomas, one prostatic adenocarcinoma, one rectal carcinoma, and one sarcoma comprise the series. Three patients presented with priapism as their chief complaint, and 3 patients presented with priapism as their first sign of recurrence. Therapy included corporeal curettage, surgery, radiotherapy, or chemotherapy. None of the modalities was entirely effective, although chemotherapy seemed to offer the best palliation. PMID:6702039

Almost all variants of malignant primary and secondary tumours of bone have been described as occurring within the jaws. Odontogenic carcinomas and sarcomas are peculiar to the jawbones and are distinctly uncommon. Non-odontogenic tumours in comparison arise with more frequency, yet the maxilla and mandible remain unusual sites for most primary and secondary non-odontogenic tumours of bone. The most commonly occurring primary bone tumours affecting the jaws include osteosarcoma, Burkitt's lymphoma and multiple myeloma, while secondary or metastatic tumours to the jaws are rare in contrast to the remainder of the skeleton.

Massive expansion of SCA2 with autonomic dysfunction, retinitis pigmentosa, and infantile spasms  

PubMed Central

Objective: To provide clinical data on a cohort of 6 patients with massive expansion (>200 CAG repeats) of spinocerebellar ataxia type 2 (SCA2) and investigate possible pathways of pathogenesis using bioinformatics analysis of ATXN2 networks. Methods: We present data on 6 patients with massive expansion of SCA2 who presented in infancy with variable combinations of hypotonia, global developmental delay, infantile spasms, and retinitis pigmentosa. ATXN2 is known to interact with a network of synaptic proteins. To investigate pathways of pathogenesis, we performed bioinformatics analysis on ATXN2 combined with known genes associated with infantile spasms, retinitis pigmentosa, and synaptic function. Results: All patients had a progressive encephalopathy with autonomic dysfunction, 4 had retinitis pigmentosa, and 3 had infantile spasms. The bioinformatics analysis led to several interesting findings. First, an interaction between ATXN2 and SYNJ1 may account for the development of retinitis pigmentosa. Second, dysfunction of postsynaptic vesicle endocytosis may be important in children with this progressive encephalopathy. Infantile spasms may be associated with interactions between ATXN2 and the postsynaptic structural proteins MAGI2 and SPTAN1. Conclusions: Severe phenotype in children with massive expansion of SCA2 may be due to a functional deficit in protein networks in the postsynapse, specifically involving vesicle endocytosis.

Infantile myofibroma is a rare and benign tumour of children presenting in the head and neck region. Rendering a final diagnosis of infantile myofibroma can be challenging in the light of nonspecific clinical, radiological findings and its histopathological similarities with a number of neoplasms especially spindle cell tumours. In this paper we discuss a case of infantile myofibroma in a 2-month-old infant, enumerating the various differential entities that have to be eliminated in reaching its specific diagnosis and highlighting the importance of immunopositivity to vimentin and smooth muscle actin (SMA) in establishing its myofibroblastic differentiation.

Erythrocyte Transketolase Activity, Markers of Cardiac Dysfunction and the Diagnosis of Infantile Beriberi  

PubMed Central

Background Infantile beriberi is a potentially lethal manifestation of thiamin deficiency, associated with traditional post-partum maternal food avoidance, which persists in the Lao PDR (Laos). There are few data on biochemical markers of infantile thiamin deficiency or indices of cardiac dysfunction as potential surrogate markers. Methodology/Principal Findings A case control study of 47 infants with beriberi and age-matched afebrile and febrile controls was conducted in Vientiane, Laos. Basal and activated erythrocyte transketolase activities (ETK) and activation (?) coefficients were assayed along with plasma brain natriuretic peptide, N-terminal pro-brain natriuretic peptide and troponin T. Basal ETK (and to a lesser extent activated ETK) and plasma troponin T were the only infant biochemical markers that predicted infantile beriberi. A basal ETK?0.59 micromoles/min/gHb gave a sensitivity (95%CI) of 75.0 (47.6 to 92.7)% and specificity (95%CI) of 85.2 (66.3 to 95.8)% for predicting infantile beriberi (OR (95%CI) 15.9 (2.03–124.2); p?=?0.008) (area under ROC curve?=?0.80). In contrast, the ? coefficient did not discriminate between cases and controls. Maternal basal ETK was linearly correlated with infant basal ETK (Pearson's r?=?0.66, p<0.001). The odds of beriberi in infants with detectable plasma troponin T was 3.4 times higher in comparison to infants without detectable troponin T (OR 3.4, 95%CI 1.22–9.73, p?=?0.019). Detectable troponin T had a sensitivity (95%CI) of 78.6 (59.0 to 91.7) % and specificity (95%CI) of 56.1 (39.7 to 71.5) % for predicting infantile beriberi. Conclusions/Significance Basal ETK is a more accurate biochemical marker of infantile beriberi than the activation coefficient. Raised plasma troponin T may be a useful indicator of infantile beriberi in infants at risk and in the absence of other evident causes.

Primary cutaneous malignant melanoma of the breast  

PubMed Central

Cutaneous malignant melanoma of the breast can be divided into two categories: primary and metastatic lesions. Cutaneous malignant melanoma of the breast is a rare tumor, accounting for less than 5% of all malignant melanomas. Clinical features and diagnostic methods of primary cutaneous malignant melanoma of the breast are similar to those arising from other cutaneous areas. Treatment of choice is wide local excision with adequate resection margin according to tumor thickness. Sentinel lymph node biopsy should be performed because the presence of lymph node metastasis is the most important prognostic factor. There have been only limited reports involving primary cutaneous malignant melanoma of the breast. Thus, we report a case of primary cutaneous malignant melanoma in a 59-year-old woman with a review of the recent literature.

Myelodysplasia and malignancy-associated vasculitis.  

PubMed

While the link between malignancy and vasculitis has been known for some time, the association of vasculitis and myelodysplastic syndrome (MDS) has only recently been reported. This article reviews the most current and landmark publications regarding MDS, as well as malignancy-associated vasculitis. We include theories of paraneoplastic associations, immune pathogenesis including an associated cytokine transcriptional factor (interferon regulatory factor-1 [IFN-1]), and the relationship to treatment. Key clinical features that suggest underlying malignancy in patients with vasculitis are highlighted. Although the association between vasculitis and malignancy is rare, leukocytoclastic vasculitis is the most common vasculitis associated with MDS, hematologic malignancies as well as solid tumors. We review several articles that demonstrate a paraneoplastic association between vasculitis and various malignancies, but overall, the connection is still unclear and not well defined. Certain features that suggest a true paraneoplastic association are outlined. Further studies are needed to advance our understanding of this complex topic. PMID:22821200

Malignant small round cell tumors  

PubMed Central

Malignant small round cell tumors are characterised by small, round, relatively undifferentiated cells. They generally include Ewing's sarcoma, peripheral neuroectodermal tumor, rhabdomyosarcoma, synovial sarcoma, non-Hodgkin's lymphoma, retinoblastoma, neuroblastoma, hepatoblastoma, and nephroblastoma or Wilms’ tumor. Other differential diagnoses of small round cell tumors include small cell osteogenic sarcoma, undifferentiated hepatoblastoma, granulocytic sarcoma, and intraabdominal desmoplastic small round cell tumor. Differential diagnosis of small round cell tumors is particularly difficult due to their undifferentiated or primitive character. Tumors that show good differentiation are generally easy to diagnose, but when a tumor is poorly differentiated, identification of the diagnostic, morphological features is difficult and therefore, no definitive diagnosis may be possible. As seen in several study reports, fine needle aspiration cytology (FNAC) has become an important modality of diagnosis for these tumors. The technique yields adequate numbers of dissociated, viable cells, making it ideally suitable for ancillary techniques. Typically, a multimodal approach is employed and the principal ancillary techniques that have been found to be useful in classification are immunohistochemistry and immunophenotyping by flow cytometry, reverse transcriptase polymerase chain reaction (RT-PCR), fluorescence in situ hybridization (FISH), and electron microscopy. However, the recent characterization of chromosomal breakpoints and the corresponding genes involved in malignant small round cell tumors means that it is possible to use molecular genetic approaches for detection.

Chemotherapy of advanced malignant teratomas.  

PubMed Central

Between 1977 and November 1979 we have treated 53 patients with malignant teratomas (43 males, 10 females). Thirty (70%) out of the 43 male patients had advanced and bulky disease at the time of presentation. Using different drug combinations in a sequential manner as described below, results are as follows: of the initial 33 male patients, 22 (67%) have discontinued treatment (mean 9.5 months). Nineteen have responded completely and 3 have static computed tomography (CT) nodules. Life-table analysis projects a survival of 66% (analysis at 1 December 1979). Nine out of 10 ovarian teratoma patients are alive. Adverse prognostic factors at the start of treatment were recognized in 9/10 male patients and the 1 female patient who have died. Although the survival of patients with malignant teratomas has improved dramatically, there are still problems with drug resistance in patients with very advanced disease. Patients with these tumours should continue to be treated in centres specializing in managing what has now become a potentially curable disease in most cases.

Oncolytic Virotherapy for Hematological Malignancies  

PubMed Central

Hematological malignancies such as leukemias, lymphomas, multiple myeloma (MM), and the myelodysplastic syndromes (MDSs) primarily affect adults and are difficult to treat. For high-risk disease, hematopoietic stem cell transplant (HCT) can be used. However, in the setting of autologous HCT, relapse due to contamination of the autograft with cancer cells remains a major challenge. Ex vivo manipulations of the autograft to purge cancer cells using chemotherapies and toxins have been attempted. Because these past strategies lack specificity for malignant cells and often impair the normal hematopoietic stem and progenitor cells, prior efforts to ex vivo purge autografts have resulted in prolonged cytopenias and graft failure. The ideal ex vivo purging agent would selectively target the contaminating cancer cells while spare normal stem and progenitor cells and would be applied quickly without toxicities to the recipient. One agent which meets these criteria is oncolytic viruses. This paper details experimental progress with reovirus, myxoma virus, measles virus, vesicular stomatitis virus, coxsackievirus, and vaccinia virus as well as requirements for translation of these results to the clinic.

Genetic heterogeneity in neuronal ceroid lipofuscinosis (NCL): Evidence that the late-infantile subtype (Jansky-Bielschowsky disease; CLN2) is not an allelic form of the juvenile or infantile subtypes  

SciTech Connect

The neuronal ceroid lipofuscinoses (NCLs) are a group of inherited neurodegenerative disorders characterized by the accumulation of autofluorescent lipopigment in neurons and other cell types. Inheritance is autosomal recessive. Three main childhood subtypes are recognized: Infantile (Haltia-Santavuori disease; MIM 256743), late infantile (Jansky-Bielschowsky disease; MIM 204500), and juvenile (Spielmeyer-Sjoegren-Vogt, or Batten disease; MIM 204200). The gene loci for the juvenile (CLN3) and infantile (CLN1) types have been mapped to human chromosomes 16p and 1p, respectively, by linkage analysis. Linkage analysis of 25 families segregating for late-infantile NCL has excluded these regions as the site of this disease locus (CLN2). The three childhood subtypes of NCL therefore arise from mutations at distinct loci. 17 refs., 2 figs., 3 tabs.

Molecular diagnostics of hematologic malignancies.  

PubMed

Hematologic malignancies, particularly lymphoma and leukemia, are a diverse group of diseases with a myriad of different presentations. Although the diagnosis of these diseases can be straightforward, there are many cases in which the diagnosis is difficult to establish with conventional methods. Molecular diagnostic testing to identify oncogenes and clonal lymphocyte populations can aid in resolving ambiguous cases, and several of these tests are routinely available for canine patients. Sensitive polymerase chain reaction-based methods are also useful for answering a variety of research questions. Here, detection of mutations of the c-kit gene in mast cell tumors, the bcr-abl fusion gene in myelogenous leukemias, and clonality of lymphocyte populations for the diagnosis and monitoring of lymphoma and leukemia are discussed.

Trauma--the malignant epidemic.  

PubMed

Trauma is the commonest cause of death in children and young adults in the USA and the UK and the incidence of both accidental and non-accidental injury continues to increase. In the Western world more pre-retirement years of life are lost annually from trauma than malignant disease, heart disease, and AIDS combined, and by the beginning of the last decade injury deaths outnumbered deaths from all other causes combined in those under 35 years of age. In South Africa, although infectious diseases continue to exact their toll, a similar pattern is emerging. Alcohol and speed are responsible for the majority of motor vehicle accidents, while the increasing ownership of firearms directly parallels the homicide rates from these weapons. Stricter application of the legislation governing alcohol, driving and firearm control is required and a regionalised trauma care programme is desperately needed to contain this epidemic.

Diffuse Malignant Mesothelioma: A Review  

PubMed Central

Diffuse malignant mesothelioma is a signal tumor of asbestos exposure. Mesothelioma incidence has been steadily rising during the past two decades, reflecting the increases in asbestos use during and following World War II. The onset of the disease follows exposure by 25 to 40 years. The dose-response relationship appears to be much lower than that for asbestosis or lung cancer—it is not known whether current levels of exposure will entail a risk for disease 30 years hence. There is no synergistic or additive interaction with smoking for this tumor. Current knowledge indicates that pleural plaques, per se, do not increase the risk for this tumor beyond that of the previous asbestos exposure alone. Durable fibers with high aspect ratios, especially amphiboles, are associated with experimental tumor induction. Treatment modalities including surgical procedures and chemotherapy with doxorubicin and 5-azacytidine offer prospects for palliation. ImagesFigure 1.Figure 2.

[PET and malignant cerebral tumors].  

PubMed

Normal biodistribution of FDG includes intense physiologic uptake in the brain, which consumes glucose. The high background therefore makes it difficult to detect the foci taking up glucose, which correspond to malignant lesions. FDG PET is nevertheless clinically useful for detecting high-grade gliomas, cerebral lymphomas and, in some cases, unexpected brain metastases in whole-body PET examinations. As an adjunct to CT and MRI, FDG-PET can make stereotactic radiosurgery more precise in targeting primary or secondary brain cancers and can differentiate necrotic fibrosis from viable cancer tissue during follow-up in cases of abnormal or equivocal MRI results. When available, methionine-(11C) PET delineates low grade gliomas accurately. Several fluorine (18F)-labeled radiopharmaceuticals have been proposed in this setting, with FET and FDOPA apparently the most effective. Four original clinical cases illustrating performances of FET and FDOPA PET in this setting are presented. PMID:16969331

Malignant hyperthermia in endosulfan poisoning.  

PubMed

We are reporting a case of endosulfan poisoning, admitted in a state of altered consciousness, vomiting, and seizure. The diagnosis was based on history, physical examination and positive reports from toxicological screening. After 8 hrs of admission, a sudden rise in EtCO(2), respiratory rate, heart rate, blood pressure, and body temperature was noted. Masseter spasm was there and patient's elbow/knees could not be bent upon manipulation. Caffeine halothane contraction test later confirmed it to be malignant hyperthermia (MH). We suggest that if there is a sudden rise in body temperature, stiffness in limbs or massater spasm in a case of endosulfan poisoning, the diagnosis of MH should be considered as one possibility when etiology is not certain.

[Thyroid nodule: benign or malignant?].  

PubMed

A thyroid nodule is a frequent occurrence. Its prevalence in a general adult population is about 50% and can even reach 67% when a cervical echography is performed. Only 5% of these nodules are cancers, and it is therefore important to avoid an useless and riskful surgery. This presentation is based on the Medical Guidelines for Clinical Practice: American Association of Clinical Endocrinologists (AACE), Associazione Medici Endocrinologi (AME) and European Thyroid Association (ETA) in 2010 for the Diagnosis and Management of Thyroid Nodules. In the absence of prospective randomized studies, these recommendations are established on the best evidence level. The patient history and clinical signs give some informations about potential risks. Thyroid tests not only evaluate thyroid functional status but TSH value and the presence of antithyroglobuline antibody seem to be associated with a higher risk of malignancy. A thyroid scintigraphy detects the presence of hot thyroid nodules. The thyroid echography is a key element before fine needle aspiration cytology. Some echographic criteria in the TIRADS (Thyroid Imaging Reporting and Data System), classification can reach an 88% sensitivity, a 49% specificity, a 49% positive predictive value, an 88% negative predictive value and a 94% diagnostic accuracy. The fine needle aspiration cytology performed with echography will be crucial to decide if the patient is to be eligible for surgery. In 70 to 80% of the cases, nodules can be classified as benign or malignant with a 92% negative predictive value for a benign diagnosis and a 100% positive predictive value for a diagnosis of cancer. The discovery of a follicular proliferation (cancer incidence of 20-30%) is a grey zone. Follicular proliferation and definite cancer lead of course to a surgical option. A decisional tree summarizes the different steps leading to a therapeutic decision. PMID:23091929

A new mouse osteopetrotic mutation, osteosclerosis, has been examined with respect to rickets. These osteopetrotic mice were hypocalcemic and hypophosphatemic, and had greatly thickened epiphyseal plates with abnormalities in matrix vesicles when compared with normal littermates.

Morphological characteristics of malignant solitary pulmonary nodules.  

PubMed

The solitary pulmonary nodule is a common radiologic abnormality, which is often detected incidentally. It is defined as focal, round or oval areas of increased opacity in the lung which are caused by a variety of disorders, including neoplasm, infection, inflammations, and vascular and congenital abnormalities. Most of the solitary pulmonary nodules are benign, but up to 30%-40% of them are malignant. The main goal of the radiologic evaluation of suspected solitary pulmonary nodules is to differentiate benign from malignant lesions as accurately as possible. The aim of the study was the assessment of the morphological characteristics of the malignant solitary pulmonary nodules. Large nodule size, irregular, spiculated margins, inhomogeneous density of nodule thick walls in cavitary nodules suggest the presence of the malignant lesion. Smooth, well-defined margins, homogeneous density or the presence of diffuse, laminated, central or popcorn-like calcifications suggest the benign nodule. Diffuse, irregular amorphous calcifications suggest the malignant process. Unfortunately there is a kind of overlapping, and some benign nodules may show features typical of malignancy, and some malignant lesions may appear benign. Morphologic characteristics in computed tomography is however helpful in differentiation of benign from malignant nodules. PMID:16145947

Intussusception Presenting with Malignant Hypertension and Lethargy  

PubMed Central

The most common cause of malignant hypertension in children is renal or renovascular pathology. The combination with lethargy suggests a diagnosis of hypertensive crisis with hypertensive encephalopathy. Here, we present a case of severe hypertension with lethargy as the sole presenting symptoms of ileocecal intussusception. Both normalized following surgical repositioning. We conclude that malignant hypertension and lethargy can be presenting symptoms of intussusception.

Preoperative predictors of malignant gastric submucosal tumor

Purpose The preoperative prediction of malignant potential in patients with gastric submucosal tumors (SMTs) plays an important role in decisions regarding their surgical management. Methods We evaluated the predictors of malignant gastric SMTs in 314 patients with gastric SMTs who underwent surgery in Chonnam National University Hospital. Results The malignant SMTs were significantly associated with age (odds ratio [OR], 1.067; 95% confidence interval [CI], 1.042 to 1.091; P < 0.0001), presence of central ulceration (OR, 2.690; 95% CI, 1.224 to 5.909; P = 0.014), and tumor size (OR, 1.791; 95% CI, 1.483 to 2.164; P < 0.0001). Receiver operating characteristic curve analysis showed that tumor size was a good predictor of malignant potential. The most relevant predictor of malignant gastric SMT was tumor size with cut-offs of 4.05 and 6.40 cm. Conclusion Our findings indicated that age, central ulceration, and tumor size were significant preoperative predictors of malignant SMTs. We suggest that 4 cm be selected as a threshold value for malignant gastric SMTs. In patients with a gastric SMT larger than 4 cm with ulceration, wide resection of the full thickness of the gastric wall or gastrectomy with adequate margins should be performed because of its malignant potential.

A well-known lesion in an unusual location: infantile myofibroma of the eyelid: a case report and review of literature.  

PubMed

Myofibroma is a neoplasia of myofibroblasts that can be solitary or multiple and it is found most commonly in the head & neck region including scalp, forehead, parotid region and oral cavity. In the eyelid it is rarely reported. It has a benign course in the solitary form and fatal in its multiple form. A 4 month male infant referred to Farabi hospital -the referral center for eye diseases- with a 2 month history of a mass in his eyelid with gradual enlargement with no other complaints. The only abnormal physical finding was a 2.5 cm mass in the eyelid. This mass was excised and sent to the hospital pathology laboratory. When confronting a spindle cell lesion with a nodular or multinodular growth pattern which appears biphasic due to alteration of light and dark staining areas, the surgical pathologist should think to the possibility of myofibroma. Its pattern of growth and architecture rules out the other differential diagnoses like nodular fasciitis, fibrous histiocytoma, infantile fibromatosis, and peripheral primitive neuroectodermal tumor, mesenchymal chondrosarcoma, malignant hemangiopericytoma, juvenile fibrosarcoma and poorly differentiated synovial sarcoma. In difficult cases immunohistochemical staining is helpful that is Vimentin & Actin positivity & Desmin, CK, EMA & S100 negativity. PMID:21287484

Autocrine growth factors and solid tumor malignancy.  

PubMed Central

The ability of malignant cells to escape the constraint that normally regulate cell growth and differentiation has been a primary focus of attention for investigators of cancer cell biology. An outcome of this attention has been the discovery that the protein products of oncogenes play a role in the activation of growth signal pathways. A second outcome, possibly related to abnormal oncogene expression, has been the discovery that malignant cells frequently show an ability to regulate their own growth by the release of autocrine growth modulatory substances. Most important, the growth of certain malignant cell types has been shown to depend on autocrine growth circuits. A malignant tumor whose continued growth depends on the release of an autocrine growth factor may be vulnerable to treatment with specific receptor antagonists or immunoneutralizing antibodies designed to break the autocrine circuit. Information is rapidly emerging concerning autocrine growth factors in selected human solid tissue malignancy. Images

There is a thickening of mesothelia of the tunica vaginalis with left sided hydrocele by ultrasonography and computed tomography scan. The tumor was resected under the diagnosis of testicular malignant tumor. However, the pathologist reported malignant mesothelioma and positive margin. He received external beam radiation therapy at a total dose of 44 Gy. Disease progression was not apparent 2 years after treatment.

Malignant Degeneration of Gastric Ulcer  

PubMed Central

Malignant degeneration is the most serious complication of gastric ulcer. Its recognition is difficult both in the early stage and in advanced cases in which only the evidence of a previous ulcer-cavity, and the radiating folds of the mucous membrane indicate progressive development of carcinoma from an original ulcer. It is impossible to say how often gastric ulcer becomes malignant; one can only state the frequency of ulcer-carcinoma, found in gastric resections. One hundred and forty-one personal cases of ulcer-carcinoma are recorded, and are divided into three groups. Group I: 41 which were diagnosed clinically and at operation as cases of ulcer, but in which histological examination showed incipient cancer. Group II: 55 diagnosed clinically as cases of ulcer, but in which a diagnosis of ulcer-carcinoma was made during operation and afterwards histologically confirmed. Group III: 45 diagnosed both clinically and macroscopically (from the typical folding of the mucous membrane) as cases of ulcer-cancer, in which the cancer had entirely overgrown the ulcer. Therefore in the series of 532 resections for gastric ulcer the frequency of ulcer-carcinoma was 20.9%, or 15.2% if the third group is omitted. In a series of 718 resections for gastric cancer, the frequency of ulcer-carcinoma was 19.6% (or 14.2% if the third group is omitted). The mortality in simple two-third resection of the stomach is low (four deaths in 99 cases = 4%). When the pancreas, liver, colon, or œsophagus, is involved, the resection mortality is high (14 deaths in 42 cases = 33.3%), but even in these cases the operation is justifiable because permanent cures were achieved in a number of cases. The prognosis in cases of ulcer-cancer is very grave. In many cases, judging from the author's own experience, patients suffering from incipient ulcer-cancer—only histologically diagnosed as cancer—die from liver metastases, in spite of radical resection. It will thus be seen that the end-results of resection for ulcer-carcinoma are actually worse than those of resection for primary carcinoma. A. Ulcer-cancer: In Group I, 35 cases were operated on before 1933, and in 18 of these (51.4%) the patients have been free from symptoms for more than five years; in Group II, 27 cases were operated on before 1933, and in four of these (14.8%) the patients are still symptom-free. In Group III, out of 37 cases operated on, only two patients (5.4%) have been symptom-free for the same period. B. Primary cancer: Out of 260 cases of resection for primary cancer before 1933, 77 patients (29.6%) are permanently cured. If the ulcer-cancer is so far advanced that the diagnosis can be made clinically, or during operation, the prognosis is extremely bad (permanent cures having been only 9.3% in the series). In cases of gastric ulcer the best plan is to carry out resection before malignant degeneration begins. The result would then be that not merely 51% but at least 90% of the patients would be alive and well after five years. ImagesFig. 1Fig. 2

Transcriptional response to GAA deficiency (Pompe disease) in infantile-onset patients.  

PubMed

Pompe disease is a genetic disorder resulting from a deficiency of lysosomal acid alpha-glucosidase (GAA) that manifests as a clinical spectrum with regard to symptom severity and rate of progression. In this study, we used microarrays to examine gene expression from the muscle of two cohorts of infantile-onset Pompe patients to identify transcriptional differences that may contribute to the disease phenotype. We found strong similarities among the gene expression profiles generated from biceps and quadriceps, and identified a number of signaling pathways altered in both cohorts. We also found that infantile-onset Pompe patient muscle had a gene expression pattern characteristic of immature or regenerating muscle, and exhibited many transcriptional markers of inflammation, despite having few overt signs of inflammatory infiltrate. Further, we identified genes exhibiting correlation between expression at baseline and response to therapy. This combined dataset can serve as a foundation for biological discovery and biomarker development to improve the treatment of Pompe disease. PMID:22658377

Infantile hepatic hemangioendothelioma is the most common vascular tumor of the liver in infancy. The diagnosis can be enunciated without histological defnition, if the clinical, analytical and images fndings are very suggestive; particularly in children less than six months old, because the biopsy is not exempt of complications. We report a female patient, four days old and 3500 g, who developed a hypovolemic shock as a complication of the biopsy from a multifocal infantile hepatic hemangioendothelioma. She developed clinical manifestations of cardiac failure and thrombocytopenia. Because of the critical clinical status we choose the medical treatment with prednisone which was administered for fve month and complete remission of the tumor was obtained. We highlight the Doppler ultrasonography as a safe and no invasive diagnosis method. Management of this disease is commented as well. PMID:24092041

IgE-mediated cow milk allergy and infantile colic: diagnostic and management challenges.  

PubMed

Cow milk allergy (CMA) is a common problem affecting 2-3% of children and is the most prevalent food allergy in infancy. Infantile colic is also a common problem in the first year of life. A frequent practice among physicians is to recommend a dairy-free diet to breast-feeding mothers and infants in cases of infantile colic. However, recent studies suggest that late introduction of potentially allergenic foods may increase the risk of developing a life-threatening food allergy. We describe two infants managed with dairy-free diet to control symptoms of colic in whom CMA developed. It is possible that unnecessary cow milk restriction may have contributed to the development of food allergy in these infants. PMID:23391944

Interneuron, interrupted: molecular pathogenesis of ARX mutations and X-linked infantile spasms.  

PubMed

X-linked Infantile Spasms Syndrome (ISSX) is a catastrophic epilepsy of early childhood with intractable seizures, intellectual disability, and poor prognosis. A spectrum of mutations in the Aristaless-Related Homeobox gene (ARX) has been linked to ISSX, and downstream targets of this interneuron-expressed transcription factor are being defined. Recent advances combining in vitro and in vivo methods have unveiled complex interactions between Arx and its binding partners and their effects on cell migration and maturation that can help explain the diversity of ARX phenotypes. New mutant mouse models of Arx-induced pathology, including a recent human triplet-repeat expansion mutation with a phenotype of infantile spasms and electrographic seizures, provide valuable tools for exploring the pathophysiology of Arx and substrates for testing novel therapies.

Spontaneous malignant transformation in craniomaxillofacial fibrous dysplasia.  

PubMed

Spontaneous malignant transformation in craniomaxillofacial fibrous dysplasia (FD) is extremely rare and its clinicopathological characteristics remain largely unknown. Here, we aimed to characterize the epidemiology and clinicopathological features of malignancies arising from preexisting FD by presenting data from a Chinese tertiary referral hospital and review of English and Chinese literatures. The craniomaxillofacial disease registry of Shanghai Ninth People's Hospital was searched and reviewed to collect relevant information for patients diagnosed as malignant transformation in craniomaxillofacial FD between January 1993 and December 2010. An English and Chinese literature review was conducted to retrieve pertinent cases published in the past 2 decades with preset inclusion criteria. All included cases were further analyzed with regard to associated clinical and pathological variables. Three cases with osteosarcoma arising from previous craniomaxillofacial FD were found at our institution and 35 other cases were identified by literature review. These uncommon entities usually occurred in adults with a mean age of 39.8 years and equal gender preponderance. Maxilla remained the most common sites for malignancies followed by mandible and zygoma. Most malignancies were diagnosed as osteosarcoma followed by fibrosarcoma, chondrosarcoma, and malignant fibrous histiocytoma. Radical resection alone or with postoperative radiotherapy/chemotherapy remains the main treatment strategy with unfavorable prognosis due to local recurrence and distant metastasis. Taken together, our findings might for the first time provide the comprehensive information regarding the epidemiology, clinicopathological features, treatment, and prognosis of malignancies in craniomaxillofacial FD. Further investigations are warranted to improve early diagnosis and proper treatment for these uncommon entities. PMID:23348272

Congenital heart disease is a feature of severe infantile spinal muscular atrophy  

Microsoft Academic Search

Objective:Homozygous deletions\\/mutations of the SMN1 gene cause infantile spinal muscular atrophy (SMA). The presence of at least one SMN2 gene copy is required for normal embryogenesis. Lack of SMN protein results in degeneration of motor neurons, while extraneuronal manifestations have been regarded as a chance association with SMA. We report on heart defects in the subgroup of congenital SMA type

Suppressed NFAT-dependent VEGFR1 expression and constitutive VEGFR2 signaling in infantile hemangioma  

Microsoft Academic Search

Infantile hemangiomas are localized and rapidly growing regions of disorganized angiogenesis. We show that expression of vascular endothelial growth factor receptor-1 (VEGFR1) in hemangioma endothelial cells (hemECs) and hemangioma tissue is markedly reduced compared to controls. Low VEGFR1 expression in hemECs results in VEGF-dependent activation of VEGFR2 and downstream signaling pathways. In hemECs, transcription of the gene encoding VEGFR1 (FLT1)

Desmoplastic infantile ganglioglioma: Report of a case and review of the literature.  

PubMed

Desmoplastic infantile ganglioglioma (DIG) is a rare supratentorial brain tumor occurring mostly before the age of 2 years. It has a good prognosis and total excision of the tumor is curative, necessitating no further treatment. An accurate pathologic diagnosis is crucial. Until now, <60 cases of this tumor type have been reported. Herein, we report a 3-month-old boy with intractable seizure who was found to have DIG after surgery. PMID:21042508

Substrate reduction therapy in the infantile form of Tay-Sachs disease.  

PubMed

Substrate reduction therapy (SRT) with miglustat has been proposed for treatment of some lysosomal storage disorders. Based on the positive experience in Gaucher disease and experimental data in Tay-Sachs (TSD) and Sandhoff animal models, the authors investigated the clinical efficacy of SRT in two patients with infantile TSD. SRT could not arrest the patients' neurologic deterioration. However, a significant drug concentration in CSF as well as macrocephaly prevention were observed. PMID:16434676

Infantile Fibromatosis of the Neck with Intracranial Involvement: MR and CT Findings  

Microsoft Academic Search

Summary: CT and MR imaging studies were performed in a 3-year-old boy with infantile fibromatosis arising from the infratemporal fossa and extending into the middle cranial fossa. On CT scans, the lesion was hyperattenuating (44-49 Hounsfield units (HU)), enhancing significantly after appli- cation of contrast material (63-66 HU). The MR images showed a multilobulated lesion of heterogeneous signal in- tensity.

Malignant transformation of human fibroblasts in vitro  

SciTech Connect

Although carcinogens cause human tumors, human cells in culture have not been successfully transformed to malignancy by exposure to carcinogens. It is now recognized that malignant transformation involves multiple changes within a cell and, therefore, successive clonal selection of cells containing such changes must occur. One explanation for the failure to induce in vitro malignant transformation of human cells could be inability to recognize cells that have undergone intermediate changes so as to expand the population, expose the cells a second time, cause further changes, etc. therefore, we transfected finite life span diploid human fibroblists with oncogenes known to be active in cells derived from human fibrosarcomas or effective in transforming animal fibroblasts to determine the phenotypes they produced. Transfection of a sis gene, or an H-, or H-ras oncogene caused the cells to acquire many characteristics of malignant cells, but not to acquire an infinite lift span or become malignant. We recently succeeded in developing an infinite life span human fibroblasts cell strain, designated MSU-1.1, which has a stable, near-diploid karyotype, composed of 45 chromosomes including two marker chromosomes. We have shown-that these cells can be transformed to malignancy by transfection of the H-, K-, or N-ras or the v-fes oncogene. All of the malignant H-, K-, or N-ras transfected derivatives examined have exhibited the stable karyotype of the parental MSU-1.1 cells. We have also found rare spontaneous clonal variants of MSU-1.1 that are malignantly transformed and have shown that malignant variants can also be induced by carcinogen treatment.

Esophageal malignancy: A growing concern  

PubMed Central

Esophageal cancer is mainly found in Asia and east Africa and is one of the deadliest cancers in the world. However, it has not garnered much attention in the Western world due to its low incidence rate. An increasing amount of data indicate that esophageal cancer, particularly esophageal adenocarcinoma, has been rising by 6-fold annually and is now becoming the fastest growing cancer in the United States. This rise has been associated with the increase of the obese population, as abdominal fat puts extra pressure on the stomach and causes gastroesophageal reflux disease (GERD). Long standing GERD can induce esophagitis and metaplasia and, ultimately, leads to adenocarcinoma. Acid suppression has been the main strategy to treat GERD; however, it has not been proven to control esophageal malignancy effectively. In fact, its side effects have triggered multiple warnings from regulatory agencies. The high mortality and fast growth of esophageal cancer demand more vigorous efforts to look into its deeper mechanisms and come up with better therapeutic options.

Improved radioimmunotherapy of hematologic malignancies  

SciTech Connect

This research project proposes to develop novel new approaches of improving the radioimmunodetection and radioimmunotherapy of malignancies by augmenting retention of radioimmunoconjugates by tumor cells. The approaches shown to be effective in these laboratory experiments will subsequently be incorporated into out ongoing clinical trials in patients. Specific project objectives include: to study the rates of endocytosis, intracellular routing, and metabolic degradation of radiolabeled monoclonal antibodies targeting tumor-associated antigens on human leukemia and lymphoma cells; To examine the effects of lysosomotropic amines (e.g. chloroquine, amantadine), carboxylic ionophores (monensin, nigericin), and thioamides (propylthiouracil), on the retention of radiolabeled MoAbs by tumor cells; to examine the impact of newer radioiodination techniques (tyramine cellobiose, paraiodobenzoyl) on the metabolic degradation of radioiodinated antibodies; to compare the endocytosis, intracellular routing, and degradation of radioimmunoconjugates prepared with different radionuclides ({sup 131}Iodine, {sup 111}Indium, {sup 90}Yttrium, {sup 99m}Technetium, {sup 186}Rhenium); and to examine the utility of radioimmunoconjugates targeting oncogene products for the radioimmunotherapy and radioimmunoscintigraphy of cancer.

Malignant ascites: pathophysiology and treatment.  

PubMed

Malignant ascites (MA) accompanies a variety of abdominal and extra-abdominal tumors. It is a primary cause of morbidity and raises several treatment challenges. MA has several symptoms, producing a significant reduction in the patient's quality of life: loss of proteins and electrolyte disorders cause diffuse oedema, while the accumulation of abdominal fluid facilitates sepsis. Treatment options include a multitude of different procedures with limited efficacy and some degree of risk. A Pubmed, Medline, Embase, and Cochrane Library review of medical, interventional and surgical treatments of MA has been performed. Medical therapy, primarily paracentesis and diuretics, are first-line treatments in managing MA. Paracentesis is widely adopted but it is associated with significant patient discomfort and several risks. Diuretic therapy is effective at the very beginning of the disease but efficacy declines with tumor progression. Intraperitoneal chemotherapy, targeted therapy, immunotherapy and radioisotopes are promising medical options but their clinical application is not yet completely elucidated, and further investigations and trials are necessary. Peritoneal-venous shunts are rarely used due to high rates of early mortality and complications. Laparoscopy and hyperthermic intraperitoneal chemotherapy (HIPEC) have been proposed as palliative therapy. Literature on the use of laparoscopic HIPEC in MA includes only reports with small numbers of patients, all showing successful control of ascites. To date, none of the different options has been subjected to evidence-based clinical trials and there are no accepted guidelines for the management of MA. PMID:22460778
