    Two cases of infantile fibrosarcoma are described. This rare childhood malignancy of mesodermal origin usually affects the lower limbs, as it did in both of our cases. Previously, the only treatment option available involved some form of radical and often mutilating surgery. More recently, combination chemotherapy has given good results, with the effect that various imaging modalities have become important in assessing both the initial extent of disease and the response to treatment. Computed tomography has the advantage of demonstrating the amount of osseous involvement, but at the expense of a considerable dose of ionizing radiation. On the other hand, magnetic resonance imaging, with its multiplanar capacity, gives superior demonstration of breaching of tissue planes, which has important implications for planning of surgery. However, as in other soft tissue tumours, changes in signal characteristics with treatment have proved less specific than was originally anticipated. (orig.)

    Cellular mesoblastic nephroma has been associated with a more aggressive course than classic mesoblastic nephroma, including local recurrences and metastases. To define the clinicopathologic and imaging features distinguishing cellular from classic mesoblastic nephroma. Retrospective review of clinical charts and imaging studies of ten children with mesoblastic nephroma from 1996 to 2007 at a large children's hospital. In six children the mesoblastic nephroma was pure cellular, in two mixed, and in two classic. The mean ages at diagnosis were 107 days for those with the cellular form, and 32 days for those with the classic form. Hypoechoic or low-attenuation regions representing necrosis or hemorrhage were found in all children with the cellular form and in none of those with the classic form. Hypertension was present in 70% and hypercalcemia in 20% of the children and resolved following nephrectomy. Two cellular tumors encased major abdominal vessels. Local recurrence and metastases occurred within 6 months of tumor resection in two children with the cellular form. Intraspinal extension and intratumoral pseudoaneurysm were seen in one child with the cellular form. The cellular tumors shared histopathologic features with infantile fibrosarcoma (IFS), and RT-PCR testing in two children with the cellular form revealed the t(12;15) ETV6-NTRK3 gene fusion common to IFS. Distinct from the classic form, cellular mesoblastic nephroma is more heterogeneous in appearance on imaging, tends to be larger and present later in infancy, and can exhibit aggressive behavior including vascular encasement and metastasis. Intraspinal extension and intratumoral pseudoaneurysm are previously unreported findings encountered in our cellular mesoblastic nephroma series. The shared histopathology and translocation gene fusion support the concept of cellular mesoblastic nephroma as the renal form of IFS. (orig.)

    Full Text Available Congenital-Infantile Fibrosarcoma (CIF is a malignant mesenchymal tumor representing 10-20% of soft-tissue tumors. Complete surgical resection is generally the treatment of choice. The most recurrent cytogenetic abnormality was identified as the traslocation t(12;15(p13:q25, which bears the fusion of Tel gene EVT6 with TrkC gene. This study describes a case of infantile fibrosarcoma of the ileum in a female newborn examined for intestinal occlusion and its laparoscopic treatment.

  4. Congenital Infantile Fibrosarcoma Causing Intestinal Perforation in a Newborn

    Full Text Available Congenital infantile fibrosarcoma (CIF is a rare malignant mesenchymal tumor and only 14 cases have been reported with gastrointestinal manifestation. We report about a female newborn delivered per emergency cesarean section at 34 weeks of gestation. Postnatally, she rapidly developed an acute abdomen and sonographic evidence of intestinal perforation requiring laparotomy on the first day of life. A perforated 2 × 3 cm sized spherical tumorous structure of the jejunum was identified. Due to unknown histopathology at this point and unclear resectional margins, she received a temporary ileostomy, which was closed two months later. Histopathology revealed a congenital intestinal fibrosarcoma without the characteristic ETV6-NTRK3 fusion transcript. In conclusion, this rare tumor must be considered as differential diagnosis of intestinal perforations in newborns.

    Purpose: To retrospectively review magnetic resonance (MR) imaging features in a series of six infantile fibrosarcomas to find out if MR can suggest this unusual diagnosis and to highlight the value of MR during and following treatment. Materials and methods: The records of six cases of histologically proven infantile fibrosarcoma were retrieved from the files of our cancer center. All imaging data available were consensually reviewed by two radiologists. Results: There were five females and one male (age range at diagnosis, 0-12 months; mean, 6 months). The most common finding was a well-circumscribed single mass in five patients (83%). All tumors had arisen on limbs; at their proximal or distal extremity or at the root of the limb. The masses were 9 cm large in mean diameter. The initial tumor signal was isointense to muscle on T1-weighted and hyperintense on T2-weighted sequences. All masses were well circumscribed and half of them contained internal fibrous septa. The internal signal was homogeneous in three patients and heterogeneous in the three others. An intense enhancement was seen in all three contrast-enhanced exams available; heterogeneous in two cases and homogeneous in one. Osseous erosion was observed in only one patient who was the only one with distant metastasis. After treatment (chemotherapy and very limited surgery), tumors had totally disappeared, leaving muscle fat infiltration in two patients and subcutaneous fat hypertrophy in one patient. Conclusion: Although imaging findings are not specific of infantile fibrosarcoma, this diagnosis could be suggested when MR imaging depicts a large well-circumscribed mass arising in a limb at birth or during the neonatal period. This mass is sometimes heterogeneous and septate and exhibits an isointense T1- and hyperintense T2-weighted signals and strong enhancement. MR is also the technique of choice for follow-up during treatment which consists nowadays almost exclusively in chemotherapy.

    Full Text Available Congenital infantile fibrosarcoma (CIFS is a rare mesenchymal tumor that is primarily developed in the soft tissue of distal extremities and occasionally in unusual locations such as the lung and retroperitoneum. It occurs mainly in children below the age of 5 years. About 200 cases have been reported in the literature so far, very few of them in new-borns. The prognosis of this tumor is relatively good compared to adult forms. We report an unusual case of CIFS occurring in new-born mimicking an hemangioma and causing hemorrhage in the neonatal period. The tumor is located in the left arm and axilla and associated with a hand malformation. A shoulder amputation is performed after chemotherapy failure. The infant is now two-years old with no recurrence.

    Full Text Available Cystinosis is an autosomal recessive, lysosomal storage disease characterised by the accumulation of the amino acid cystine in different organs and tissues. It is a multisystemic disease that can present with renal and extra-renal manifestations. In this report, we present the first case of transplanted nephropathic cystinosis in a Tunisian child. A 4-year-old Tunisian boy born to nonconsanguineous parents, was treated in our medical services in 1990 for cystinosis. Since the age of five months, he developed symptoms of severe weight loss, vomiting, dehydration, and polyuria. He manifested the Toni Debré Fanconi syndrome. Slit lamp examination of the anterior segment of both eyes revealed fine, shiny crystal-like deposits diffusely distributed in the corneal epithelium and the stroma. Our patient had renal failure. At the age of seven, he reached terminal chronic renal failure and was treated with peritoneal dialysis. Hemodialysis was started at the age of nine years. At the age of 13 years, he received a renal transplantation and was started on cysteamine 1999, five months after the renal transplantation. Currently, the patient is 28-year-old. The graft has survived 15 years after the transplantation. Renal functions were stable with a serum creatinine of 123 μmol/L at last follow-up.

    Cystinosis is the most common cause of inherited renal Fanconi syndrome in young children, and typically presents with laboratory findings of a proximal tubulopathy and corneal crystals by one year of age. We describe here renal biopsy findings in a 20-month-old patient with an atypical presentation of distal renal tubular acidosis, diabetes insipidus, and the absence of corneal crystals. Although renal biopsy is usually not necessary to establish the diagnosis of cystinosis, when the patient presents with atypical signs and symptoms, a renal biopsy may be extremely valuable. A 20-month-old boy presented with failure to thrive, polyuria, polydipsia, and rickets. He initially showed evidence of a renal tubular acidosis, mild renal insufficiency, and nephrogenic diabetes insipidus. His initial ophthalmologic examination did not demonstrate corneal crystals. His subsequent workup revealed phosphaturia, suggesting a partial proximal tubulopathy. Concomitantly, a renal biopsy revealed prominent podocytes with an immature glomerular appearance, and electron microscopy analysis showed numerous intracellular crystals within tubular epithelial cells. Subsequent laboratory and genetic testing confirmed a diagnosis of infantile nephropathic cystinosis. This case highlights the variability in the clinical presentation of cystinosis, resulting in an uncommon clinical picture of a rare disease. Given that treatment is available to prolong renal function and minimize the extra-renal manifestations of this disorder, early diagnosis is essential. It is important to raise the index of suspicion of cystinosis by recognizing its subtle morphological changes in young patients, and that nephrogenic diabetes insipidus can be secondary to this disorder.

    A general clinical-radiological description of fibrosarcoma of bone, including tumours with features of malignant fibrous histiocytoma is presented. 104 patients with fibrosarcoma of the long bones are analysed in terms of age and sex distribution, symptoms, duration of symptoms and tumour localization. The radiological findings obtained in patients with fibrosarcoma of the long bones are discussed. The treatment and course of fibrosarcoma of the long bones are discussed. Data on the type of therapy given were available on 103 patients: 67 were treated by ablative surgery either immediately or within three months of preceding local surgery and/or radiotherapy. In the remaining 36 cases treatment consisted of local surgery, radiotherapy or a combination of these, or non-curative (palliative) treatment. In a few cases ablative surgery was performed at a later stage. 13 patients with fibrosarcoma of the axial skeleton and 14 with fibrosarcoma of the jaws are considered. A causistic discussion of patients with a secondary fibrosarcoma is presented. Secondary fibrosarcoma was found in a total of 19 patients (14%); 4 after irradiation. The features of significance for the course of the disease are discussed: general features such as age and sex, tumour localization in the long bones, presence or absence of a pathological fracture, and the radiological and histological characteristics of the tumour. The type of therapy and the occurrence of lung metastases in relation to the course of the disease is also discussed. (Auth.)

    Full Text Available Meningeal fibrosarcomas are rare tumors. Only 41 cases have been reported in the literature to date. Primary central nervous system fibrosarcomas are very aggressive neoplasms and have a poor prognosis. Hence they need to be correctly diagnosed. This is a case of a 13-year old boy with intracranial space occupying lesion. The mass was completely removed and histological examination was characteristic of meningeal fibrosarcoma. The pathological diagnosis is usually made on routine light microscopic examination; however, occasionally these may be difficult to distinguish from other malignant neoplasms such as gliomas, meningiomas and metastases. The diagnosis of fibrosarcoma is based on the identification of a predominant herringbone architectural pattern, the overall uniformity of the spindle cell population, the prominent vimentin positivity, and the presence of pericellular reticulin fibre network. IHC helps to exclude other diagnoses.

    Objective: To study the clinic value of DTPA renal dynamic imaging in the functional evaluation of infantile hydronephrosis and clarify its application value, and lay the foundation for DTPA renal dynamic imaging in diagnosis and treatment of infantile hydronephrosis. Methods: 70 infants with hydronephrosis in our hospital whose mean age was (2.32±2.1) years (rang from 37 d to 6 years) were selected. There were 56 males and 14 females. 18 normal infants with mean age (2.66±2.01) years (rang from 41 d to 6 years, 15 males and 3 females) were selected as control group during the same period. Technetium-99m-labelled DTPA ( 99m Tc-DTPA) was taken as agent, and the dose of 99m Tc was 18.5 MBq per infant. GE Infinia SPECT was used as imaging equipment. The time-activity curve was generated in the imaging system automatically. The glomerular filtration rate (GFR) was detected by DTPA renal dynamic imaging through drawing the region of interest (ROI). Results: 83 kidneys were suffered from hydronephrosis diagnosed by B-ultrasound among 70 infant patients, while 104 abnormal kidneys were diagnosed by renal dynamic imaging. The detection rate of renal dysfunction by renal dynamic imaging was higher than that of B-ultrasound (t=7.751, P=0.005). Among 83 kidneys suffered from hydronephrosis diagnosed by B-ultrasound, the continued rising type was 56 cases (67.47% ); the parabolic type was cases (7.23% ); the high linear extension type was 14 cases (16.87% ); and the low linear extension type was 7 cases (8.43% ). The GFR value of linear extension type was lower than normal control group, the difference was significant (P<0.05), and the another three types had no significant differences compared with control group. Conclusion: For infantile hydronephrosis, DTPA renal dynamic imaging can observe not only the abnormal morphology of kidney, but also the function of split kidney; and it can provide objective basis for diagnosis and treatment of infantile hydronephrosis.

  15. INFANTILE HAEMANGIOMA

    2016-06-01

    Full Text Available Infantile hemangiomas are the most common softtissue tumors of infancy, occurring in approximately 3 to 10 percent of one-year-old children, with predominance in females. Despite the frequency of these tumors, their pathogenesis is not completely understood, and the best approach to their management remains controversial. They have a well-described natural history of rapid growth during early infancy followed by gradual involution, often leading to complete regression. Because of their spontaneous involution, most infantile hemangiomas do not require therapeutic intervention. However, in 10 to 15 % of cases, treatment is necessary because of local complications, life or physiological functioning is threatened or the long-term esthetic risk is too high.

  16. Infantile colic

    Full Text Available Infantile colic is one of the most common functional gastrointestinal disorders in infants, usually occurring between 2 weeks to 4 months of age. According to the definition, infantile colic is characterised by episodes of inconsolable crying, generally observed in the evening. Although these symptoms usually resolve spontaneously in the first six months of life, they often cause parental anxiety, leading to repeated medical appointments in search for help. Despite 40 years of research, the causes of this disorder are still unclear; hypersensitivity to cow’s milk protein, lactose intolerance, impaired gut microbiota, immaturity of the nervous system, the negative impact of tobacco smoke, inappropriate childcare techniques and psychosocial factors are believed to be involved in the pathogenesis. The treatment involves behavioural methods, i.e. reducing infant exposure to external stimuli. Breastfeeding mothers are advised to eliminate caffeine and hot spices from their diet and, in some cases, switch to a dairy-free diet. For formula-fed infants, it is recommended to use hydrolysates with a high degree of hydrolysis. Simethicone is commonly used in the pharmacological treatment as it reduces the surface tension of intestinal gases, enabling their easier elimination. The Rome III Diagnostic Criteria recommend to appropriately continue any method if considered effective by the parents, provided that there are no harmful consequences.

    Congenital infantile fibrosarcoma (CIFS) exceptionally occurs in the meninges, with no cases reported before or at birth. We report herein a meningeal CIFS diagnosed in a fetus at 40 weeks of gestation (WG). A 24-year-old pregnant woman was referred to the obstetrics department for vaginal bleeding. A severe right hydrocephalus due to a large tumor invading the left hemisphere and ventricles was discovered in the fetus, and medical termination of the pregnancy was achieved. Histological examination revealed a highly cellular spindle or ovoid shaped cell proliferation organized in interlacing bundles; it was diffusely positive for vimentin, and scarcely for SMA (smooth muscle actin). NFs (neurofilaments), NeuN, S100 protein, desmin, GFAP (glial fibrillary acidic protein), Olig2, chromogranin, synaptophysin, CD31, CD34, BCL2, and EMA (epithelial membrane antigen) antibodies were negative. Ki67 antibody labeled 20% of the nuclei. A reverse transcription polymerase chain reaction assay was performed to detect the gene fusion ETV6-NTRK3 transcript. Despite negative results, it was concluded to be a CIFS of the meninges. CIFS of the meninges during the fetal period has never been reported. Its diagnosis is based on immunohistochemistry, and, whenever possible, on the detection of the reciprocal translocation t (12;15) resulting in the gene fusion ETV6-NTRK3. Its prognosis depends on rapid growth and local invasiveness leading to cerebral structure damage.

E-mail: georgiamode@hotmail.com Intestinal neoplasms are uncommon in dogs, and among the most frequently diagnosed are smooth muscle, lymphomas and carcinomas. The fibrosarcoma is extremely rare in the intestine of animals of this species therefore, little is known about the macroscopic and behavior of this tumor. Given this unusual intestinal disease in dogs, the present study aimed to report a case of intestinal fibrosarcoma in a poodle breed dog, 15 years old, with no apparent clinical signs. The mass was pedunculated, whitish and firm consistency. The diagnosis was made by histopathology. After four months of surgical excision, there was no recurrence and metastasis. We conclude that the intestinal fibrosarcoma has low aggressiveness, are rare and can present macroscopic pediculated.

    The carcinogenic effect of ionizing radiation is a well known phenomenon. However, the induction of malignancies following irradiation for head and neck cancers is quite rare. Most reported cases are osteogenic sarcomas with soft tissue sarcomas encountered less often. We report a rare case of fibrosarcoma of the larynx, following radiation therapy for glottic carcinoma.

    An increasing number of congenital and infantile sarcomas displaying a primitive, monomorphic spindle cell phenotype have been characterized to harbor recurrent gene fusions, including infantile fibrosarcoma and congenital spindle cell rhabdomyosarcoma. Here, we report an unusual spindle cell sarcoma presenting as a large and infiltrative pelvic soft tissue mass in a 4-month-old girl, which revealed a novel TFG-MET gene fusion by whole transcriptome RNA sequencing. The tumor resembled the morphology of an infantile fibrosarcoma with both fascicular and patternless growth, however, it expressed strong S100 protein immunoreactivity, while lacking SOX10 staining and retaining H3K27me3 expression. Although this immunoprofile suggested partial neural/neuroectodermal differentiation, overall features were unusual and did not fit into any known tumor types (cellular schwannoma, MPNST), raising the possibility of a novel pathologic entity. The TFG-MET gene fusion expands the genetic spectrum implicated in the pathogenesis of congenital spindle cell sarcomas, with yet another example of kinase oncogenic activation through chromosomal translocation. The discovery of this new fusion is significant since the resulting MET activation can potentially be inhibited by targeted therapy, as MET inhibitors are presently available in clinical trials. © 2017 Wiley Periodicals, Inc.

    2000-09-01

    A 12-yr-old captive intact male maned wolf (Chrysocyon brachyurus) was diagnosed with a fibrosarcoma of the incisive bones. The mass was excised by rostral maxillectomy, and the wolf remained normal and on display with good function and cosmetics for 7 mo. Subsequently, it became weak, ataxic, and dyspneic and was euthanatized. At necropsy, there was a small regrowth of the maxillary tumor, a metastatic mediastinal mass, and multiple metastatic lung masses, suggesting that oral fibrosarcoma in maned wolves behaves similarly to oral fibrosarcoma in domestic canines. Aggressive surgical treatment of oral fibrosarcoma in this species can achieve good functional and cosmetic results.

    A female, reticulated python (Python reticularis) of unknown age was presented with a history of lethargy, weakness, and distended coelom. Physical examination revealed severe dystocia and stomatitis. The reticulated python was euthanized due to a poor clinical prognosis. Postmortem examination revealed marked distention of the reproductive tract with 26 eggs (10-12 cm in diameter), pericardial effusion, and a slightly firm, pale tan mass (3-4 cm in diameter) adhered to the endocardium at the base of aorta. Based on histopathologic and transmission electron microscopic findings, the diagnosis of endocardial fibrosarcoma was made.

    Full Text Available Introduction: The anticancer effect of tomato lycopene has been approved in some cancers. This study was aimed to determine the prohibitive and therapeutic effects of tomato extract on the growth of fibrosarcoma in mice. Materials and Methods: In this experimental study 3 groups of 10 male Balb/c mice were injected subcutaneously with 5×105 WEHI-164 tumor cells in the chest area. Prevention group was fed tomato extract (5 mg for a 4 week period (from 2 weeks before tumor cell injection up to 2 weeks after injection and the treatment group was fed simultaneously with tumor cell injection up to two weeks after injection daily by an oral gastric tube. The tumors areas were measured and recorded on days 10, 12, 14, 16, 18, 20 and 22. The data were analyzed using Kruskal-Wallis and Mann-Whitney tests. Results: The results showed that the tumor areas in control group were significantly more after the intervention than two groups of treatment and prevention (p<0.05. The difference was not statistically significant between the two groups of prevention and treatment. Conclusion: With emphasize on antioxidant of tomato, it seems that tomato extract has an important role in prevention and control fibrosarcoma growth.

    Fibrosarcomas are highly aggressive malignant tumors. It is urgently needed to explore targeted drugs and modalities for more effective therapy. Matrix metalloproteinases (MMPs) play important roles in tumor progression and metastasis, while several MMPs are highly expressed in fibrosarcomas. In addition, tissue inhibitor of metalloproteinase 2 (TIMP2) displays specific interaction with MMPs. Therefore, TIMP2 may play an active role in the development of fibrosarcoma-targeting agents. In the current study, a TIMP2-based recombinant protein LT and its enediyne-integrated analog LTE were prepared; furthermore, the fibrosarcoma-binding intensity and antitumor activity were investigated. As shown, intense and selective binding capability of the protein LT to human fibrosarcoma specimens was confirmed by tissue microarray. Moreover, LTE, the enediyne-integrated analog of LT, exerted highly potent cytotoxicity to fibrosarcoma HT1080 cells, induced apoptosis, and caused G2/M arrest. LTE at 0.1 nM markedly suppressed the migration and invasion of HT1080 cells. LTE at tolerated dose of 0.6 mg/kg inhibited the tumor growth of fibrosarcoma xenograft in athymic mice. The study provides evidence that the TIMP2-based reconstituted analog LTE may be useful as a targeted drug for fibrosarcome therapy.

    Congenital fibrosarcoma is a rare, soft tissue malignancy of infancy, most commonly involving the distal extremities. We report a case of congenital fibrosarcoma of the ileum in a 5-day-old boy who presented with an acute abdomen due to ileal perforation. Partial ileal resection was carried out with successful anastomosis. Grossly, the resected small bowel showed focal luminal stenosis with a thickened, indurated wall. Histology showed a transmural primitive spindle cell proliferation with a morphology consistent with congenital fibrosarcoma. The associated hallmark chromosomal translocation t(12;15)(q13;q25) was demonstrated by reverse transcriptase polymerase chain reaction.

    A 24-year-old womanpresented with ameloblastic fibrosarcoma arising from ameloblastic fibroma. The delayed presentation accounted for the extensive destruction of the mandible and complete occlusion of her oral cavity. This resulted in an inability to eat and maintain oral hygiene. A multidisciplinary team management approach involved nutritional optimisation, segmental mandibulectomy, reconstruction with a reconstructive plate and a free anterolateral thigh flap to line the the floor of mouth. Functional and aesthetic outcome was acceptable, and the patient is planned for secondary free fibular flap bony reconstruction. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    We investigated the effect of metformin and caffeine on fibrosarcoma in hamsters. 32 Syrian golden hamsters of both sexes, weighing approximately 100 g, were randomly allocated to 3 experimental and 2 control groups, with a minimum of 6 animals per group. 2 x 106 BHK-21/C13 cells in 1 ml were injected subcutaneously into the animals' back in 4 groups. The first experimental group started peroral treatment with metformin 500 mg/kg daily, the second with caffeine 100 mg/kg daily and the third with a combination of metformin 500 mg/kg and caffeine 100 mg/kg daily, via a gastric probe 3 days before tumor inoculation. After 2 weeks, when the tumors were approximately 2 cm in the control group, all animals were sacrificed. The blood was collected for glucose and other analyses. The tumors were excised and weighed and their diameters were measured. The tumor samples were pathohistologically (HE) and immunohistochemically (Ki-67, CD 31, COX IV, GLUT-1, iNOS) assessed and the main organs toxicologically analyzed, including the control animals that had received metformin and caffeine. Tumor volume was determined using the formula LxS2/2, where L was the longest and S the shortest diameter. Ki-67-positive cells in the tumor samples were quantified. Images were taken and processed by software UTHSCSA Image Tools for Windows Version 3.00. Statistical significances were determined by the Student's t-test. The combination of metformin and caffeine inhibited fibrosarcoma growth in hamsters without toxicity. Administration of metformin with caffeine might be an effective and safe approach in novel nontoxic adjuvant anticancer treatment.

    Blood flow measurements following i.v. infusion of iodi-antipyrine labelled with 14 C ( 14 C-IAP) and blood volume measurements following i.v. injection of 125 I human serum albumin and 51 Cr-labelled red blood cells were made in a transplanted rat fibrosarcoma for comparison with various normal tissues. The tumour-blood partition co-efficient for 14 C-IAP w as found to be 0.79 ± 0.07 which is similar to most of the normal tissues studied. The solubility of 14 C-IAP in plasma was found to be higher than that in whole blood. Blood flow to tumours 3 was found to be 17.9 ± 4.0 ml blood 100 g tissue -1 xmin -1 . These values were considered to be primarily measurements of nutritive flow. Blood in the tumours was found to occupy around 1% of the tissue space which was similar to that found for normal muscle and skin. There was no direct correlation between % blood volume and blood flow for the different tissues studied. Th haematocrit of blood contained in tumour tissue was calculated to be significantly lower than that of blood contained in the normal tissues. It was suspected that permeability of tumour blood vessel walls to 125 I-HSA could have accounted for this difference. (author). 41 refs.; 2 figs.; 3 tabs

    Full Text Available Objective. To characterize and evaluate CT and MRI features of extremity soft tissue adult fibrosarcoma. Methods. CT and MRI images from 10 adult patients with pathologically proven fibrosarcomas were retrospectively analyzed with regard to tumor location, size, number, shape, margins, attenuation, signal intensity, and enhancement patterns on MR images. Additionally, the relationships between lesions, deep fascia, and change in adjacent bones were also assessed. Results. Nineteen tumor lesions in 10 patients were selected for this study. Eighteen lesions were lobulated and one was oval in shape. Most cases were located under the deep fascia, including seven cases that had a nodular lump adjacent to the deep fascia and one case that had broken lesion through the deep fascia. On CT, the adult fibrosarcomas mostly showed iso-attenuated soft tissue masses (n=6. On MRI, all the cases (n=9 displayed low signal on T1-weighted imaging (T1WI and heterogeneous low and high intensity signals on T2-weighted imaging (T2WI, with band-like areas of low signal on both T1WI and T2WI. On contrast-enhanced MRI images, three cases showed heterogeneous peripheral enhancement and one case demonstrated a spoke-wheel-like enhancement. Eight cases showed muscle edema signals in the peritumoral muscle and one case involved adjacent bone. Conclusion. CT and MR imaging have respective advantages in diagnosing adult fibrosarcoma. Combined application of CT and MR is recommended for patients with suspected adult fibrosarcoma.

The content of theoretical construct «infantilism» is analyzed. Methods. The methods of theoretical research involve analysis and synthesis. The age and content criteria are analysed in the context of childhood and adulthood. The traits which can be interpreted as adult infantile traits are described. Results. The characteristics of adult infantilism in modern world taking into account the increasing of information flows and socio-economic changes are defined. The definition of the concept «infantilism» including its main features is given. Infantilism is defined as the personal organization including features and models of the previous age period not adequate for the real age stage with emphasis on immaturity of the emotional and volitional sphere. Scientific novelty. The main psychological characteristics of adulthood are described as the reflection, requirement to work and professional activity, existence of professional self-determination, possession of labor skills, need for selfrealization, maturity of the emotional and volitional sphere. As objective adulthood characteristics are considered the following: transition to economic and territorial independence of a parental family, and also development of new social roles, such as a worker, spouse, and parent. Two options of a possible operationalization of concept are allocated: objective (existence / absence in real human life of objective criteria of adulthood and subjective (the self-report on subjective feeling of existence / lack of psychological characteristics of adulthood. Practical significance consists in a construct operationalization of «infantilism» which at the moment has so many interpretations. That operationalization is necessary for the further analysis and carrying out various researches.

    Because of the high resistance rate of fibrosarcomas against cytotoxic agents clinical chemotherapy of these tumors is not established. A better understanding of the diverse modes of tumor cell death following cytotoxic therapies will provide a molecular basis for new chemotherapeutic strategies. In this study we elucidated the response of a fibrosarcoma cell line to clinically used cytostatic agents on the level of gene expression. HT1080 fibrosarcoma cells were exposed to the chemotherapeutic agents doxorubicin, actinomycin D or vincristine. Total RNA was isolated and the gene expression patterns were analyzed by microarray analysis. Expression levels for 46 selected candidate genes were validated by quantitative real-time PCR. The analysis of the microarray data resulted in 3.309 (actinomycin D), 1.019 (doxorubicin) and 134 (vincristine) probesets that showed significant expression changes. For the RNA synthesis blocker actinomycin D, 99.4% of all differentially expressed probesets were under-represented. In comparison, probesets down-regulated by doxorubicin comprised only 37.4% of all genes effected by this agent. Closer analysis of the differentially regulated genes revealed that doxorubicin induced cell death of HT1080 fibrosarcoma cells mainly by regulating the abundance of factors mediating the mitochondrial (intrinsic) apoptosis pathway. Furthermore doxorubicin influences other pathways and crosstalk to other pathways (including to the death receptor pathway) at multiple levels. We found increased levels of cytochrome c, APAF-1 and members of the STAT-family (STAT1, STAT3), while Bcl-2 expression was decreased. Caspase-1, -3, -6, -8, and -9 were increased indicating that these proteases are key factors in the execution of doxorubicin mediated apoptosis. This study demonstrates that chemotherapy regulates the expression of apoptosis-related factors in fibrosarcoma cells. The number and the specific pattern of the genes depend on the used cytotoxic drug

Métodos: Foram avaliados retrospectivamente, através de questionário, pacientes com idade de até 15 anos, internados no Serviço de Pediatria do HCPA, no período de janeiro de 2002 a setembro de 2007.   Resultados: Dos 52 pacientes incluídos, 63% apresentavam TB pulmonar. Das formas extra-pulmonares, a meningoencefalite foi a mais prevalente (22%. Comorbidades foram dectadas em 31 (60% pacientes, dos quais 15 (29% apresentavam desnutrição grave, 9 (18% HIV positivo e 7 (13% pneumopatia crônica. Das manifestações clínicas, febre e tosse estavam presentes na maioria dos pacientes. O padrão radiológico predominante foi o de consolidação pulmonar (51%. A maioria dos pacientes referia história de contato com paciente bacilífero (64%. Conclusão: A TB pulmonar representa a principal forma de apresentação clínica da TB, sendo o diagnóstico feito de forma presuntiva na maioria dos casos. O diagnóstico baseado na comprovação bacteriológica foi obtido numa minoria de pacientes, demonstrando a importância dos achados clínico-laboratoriais, história epidemiológica e vacinal para o diagnóstico. Nesse sentido, a criação de escores tem se tornado uma ferramenta de fácil acesso e com razoável acurácia para auxiliar o diagnóstico de TB em serviços de baixa complexidade, especialmente o ambulatorial.

    Rickets is a complication of infantile osteopetrosis and pre-treatment recognition of this complication is important. To describe four children with infantile osteopetrosis complicated by rickets (osteopetrorickets) and review the relevant literature. Retrospective chart analysis of four infants with osteopetrorickets and a systematic review of the relevant literature. We saw five children with infantile osteopetrosis, of whom four had superimposed rickets, for a period of 12 years. The review of the literature (including the current four children), yielded 20 children with infantile osteopetrorickets. The children ranged in age from 2 months to 12 months. In all children, hepatosplenomegaly was found. Sixteen (80%) children had visual impairments and eight (40%) children had hearing impairments. Serum calcium-phosphorus product was less than 30 in 18 children (90%). Twelve children (60%) were hypocalcemic and 18 (90%) were hypophosphatemic. In all children, the radiological examination demonstrated diffuse bony sclerosis and metaphyseal splaying and fraying of long bones. Five children (25%) had pathological fracture of extremities and 15 (75%) had rachitic rosary. Rickets as a complication to infantile osteopetrosis is not uncommon. Skeletal roentgenograms are of critical importance in the diagnosis of both osteopetrosis and superimposed rickets.

    Mitochondrial diseases are usually severe and progressive conditions; however, there are rare forms that show remarkable spontaneous recoveries. Two homoplasmic mitochondrial tRNA mutations (m.14674T>C/G in mt-tRNA(Glu)) have been reported to cause severe infantile mitochondrial myopathy in the first months of life. If these patients survive the first year of life by extensive life-sustaining measures they usually recover and develop normally. Another mitochondrial disease due to deficiency of the 5-methylaminomethyl-2-thiouridylate methyltransferase (TRMU) causes severe liver failure in infancy, but similar to the reversible mitochondrial myopathy, within the first year of life these infants may also recover completely. Partial recovery has been noted in some other rare forms of mitochondrial disease due to deficiency of mitochondrial tRNA synthetases and mitochondrial tRNA modifying enzymes. Here we summarize the clinical presentation of these unique reversible mitochondrial diseases and discuss potential molecular mechanisms behind the reversibility. Understanding these mechanisms may provide the key to treatments of potential broader relevance in mitochondrial disease, where for the majority of the patients no effective treatment is currently available.

    Full Text Available En Nuestra Portada se muestra un fragmento de la obra Juegos Infantiles (Kinderspelen, original del pintor flamenco Pieter Bruegel el Viejo. Pieter Bruegel ha sido un artista de valoración tardía. No fue hasta principios del siglo xx que la grandeza de su arte mereció el reconocimiento de los críticos. Sorprendentemente es prácticamente desconocido en su etapa de formación, porque únicamente existe una corta descripción biográfica publicada en 1604 por Van Manden. En esta bibliografía, Bruegel era presentado como un ignorante dedicado a la pintura cómica y campestre. Según Van Manden, había nacido en Bruegel, un pueblo cercano a Breda, del cual tomó el apellido. Esta afirmación es falsa, porque parece probado que lo había heredado de su padre. La realidad es, como señala en 1567 Ludovic Guicciardini, que “Pietro Brueghel de Breda es un gran imitador de la ciencia y de la fantasía de Hieronymus Bosco”. El año de nacimiento es incierto y se sitúa entre 1525 y 1530.

En consecuencia, es necesario poner todo el cuidado y atención posibles para conseguir un ambiente, a la vez agradable y práctico, que favorezca la vida y el aprendizaje de los niños y niñas de cero a seis años. Al principio de cada curso escolar se planificarán los aspectos físicos del aula, se organizarán los materiales y se distribuirá el tiempo. Para ello, deberán ser tenidas en cuenta las necesidades infantiles y los ámbitos madurativos en los que cada niña y cada niño deben progresar.ABSTRACT: The organization of the classroom is an important "tool" in the hands of the educator, especially during the early years. Consequently, it is necessary to take great care and give as much attention as possible to achieving an environment which is both pleasant and practical, as well as favourable to the lives and learning of children under six years of age. At the beginning of the school year the physical aspects of the classroom will be planned, the material organized and time distributed. For this purpose, the needs of the children, and the areas in which each child should advance and mature, must be taken into account.

    Infantile haemangiomas are benign tumours produced by the proliferation of endothelial cells of blood vessels, with a high incidence in children under the age of one year (4-10%). It is estimated that 12% of them require treatment. This treatment must be administered according to clinical practice guidelines, expert experience, patient characteristics and parent preferences. The consensus process was performed by using scientific evidence on the diagnosis and treatment of infantile haemangiomas, culled from a systematic review of the literature, together with specialist expert opinions. The recommendations issued were validated by the specialists, who also provided their level of agreement. This document contains recommendations on the classification, associations, complications, diagnosis, treatment, and follow-up of patients with infantile haemangioma. It also includes action algorithms, and addresses multidisciplinary management and referral criteria between the different specialities involved in the clinical management of this type of patient. The recommendations and the diagnostic and therapeutic algorithms of infantile haemangiomas contained in this document are a useful tool for the proper management of these patients.

    Sclerosing epithelioid fibrosarcoma (SEF) is a rare variant of low-grade fibrosarcoma, with specific histological and immunohistochemical features and a poor prognosis. We report a case of SEF of the paravertebral column in a 49-year old male who presented a paraspinal mass with extension into the L4-L5 neural foramen and invasion of the L5 nerve root. Histology of the tumourectomy specimen and its immunohistochemical study led to the diagnosis of SEF. This case was particularly unusual due to its paravertebral column location and, despite its low grade, illustrates the malignant potential of SEF. Copyright © 2012 Sociedad Española de Neurocirugía.

    A 31-year-old woman presented with general malaise, back pain, and edema of the lower extremities. A chest X-ray film showed an enlarged cardiac shadow and clear lung fields. A pericardial lesion with decreased activity on blood pool imaging and increased uptake on gallium citrate Ga67 imaging displaced the heart upwards and to the left. The pericardial mass showed an inhomogeneous signal intensity on MRI and was large enough to obstruct the venous return by compressing the heart. At operation, the mass was found to originate from the pericardium and was histologically identified as a malignant fibrosarcoma. Twelve years before, the patient had undergone an operation for the removal of a pericardial tumor which was histologically identified as a benign hemangioma. In view of the rarity of pericardial tumors, the present tumor is suspected to have undergone a transformation from benign hemangioma to malignant fibrosarcoma. (orig.)

    Full Text Available Phospholipids were isolated from camel milk and identified by using high performance liquid chromatography and gas chromatography-mass spectrometry (GC/MS. Anticancer drug etoposide (ETP was entrapped in liposomes, prepared from camel milk phospholipids, to determine its activity against fibrosarcoma in a murine model. Fibrosarcoma was induced in mice by injecting benzopyrene (BAP and tumor-bearing mice were treated with various formulations of etoposide, including etoposide entrapped camel milk phospholipids liposomes (ETP-Cam-liposomes and etoposide-loaded DPPC-liposomes (ETP-DPPC-liposomes. The tumor-bearing mice treated with ETP-Cam-liposomes showed slow progression of tumors and increased survival compared to free ETP or ETP-DPPC-liposomes. These results suggest that ETP-Cam-liposomes may prove to be a better drug delivery system for anticancer drugs.

    Naturally occurring fibrosarcoma of the thyroid gland is very rare. Only 5 cases of this tumor have been reported in Japan. Recently, we diagnosed a thyroid fibro sarcoma in a 46-year-old woman. It started as a papillary cystadenoma 26 years ago, followed by the appearance of papillary adenocarcinoma 6 years later. At that time most of the tumor was removed, except for a small portion which had invaded the trachea, and 5,000 rads of /sup 60/Co was given postoperatively to her neck. The tumor was quiescent for 18 years and then fibrosarcoma appeared in the same region. We think that this tumor may be a radiation-induced sarcoma.

    Full Text Available Case summary A 14-year-old, female neutered domestic shorthair presented for dyspnoea. Thoracic ultrasonography and radiography showed that a heterogeneous mass was present within the pericardial sac, and the mass continued caudally with the mesenteric fat. On CT, the outline of the diaphragm was not continuous and there was an obvious defect with diaphragmatic thickening present at the mid-level of the liver. A pleural effusion and a small-volume pericardial effusion were also present. A ventral midline coeliotomy and median sternotomy revealed a 5 × 6 × 7 cm firm, irregular, tan-coloured soft tissue mass within the pericardial sac attached to both the diaphragmatic defect and liver. The mass was carefully dissected away from the heart and the diaphragmatic defect was repaired with primary closure. Postoperatively, the cat had a persistent pneumothorax that required continuous pleural suction for 41 h. The cat died 44 h postoperatively. Histopathology and immunohistochemistry confirmed the mass to be a hepatic fibrosarcoma incarcerated in a peritoneopericardial diaphragmatic hernia (PPDH. Relevance and novel information This is the first reported case of metaplastic transformation of liver into a sarcoma in a cat with PPDH. In addition, hepatic fibrosarcoma is a rarely reported location for fibrosarcoma in this species.

    Tests aimed at a conditioning of tumours by means of x-ray irradiation and high-frequency hyperthermia. Methyl cholanthrene-induced fibrosarcoma (IMCM) and its transplant version (T-IMCM) produced at the neck of NMRI-mice at a critical localization immediately next to vital organs, served as a test system since it is almost resistant to simple oncolysis. Individual therapy components were compared for their mutual enhancement of efficacy in 16 test groups, and the triple combination (Cl + X-ray + HFH) was tested in relapse application as well. A 2000-R-x-ray irradiation was followed by almost simultaneous 4 min HF heating and i.v. spore administration at 12 h intervals. Assessment criteria were tumour growth, survival rates and times, absence of recidivity and healing, analysis of post-mortem findings and dimension or duration of lyses. In addition, the two tumour types of induction and transplant tumour were compared. The typical course of clostridial oncolysis can be confirmed in principle. Results show that it is possible by means of additional physical methods as were applied, to increase the systemically apathogenic and selective therapy principle of rather negligible oncolysis to over 80% (IMCM) or 97% (T-IMCM). Concerning the MCA fibrosarcoma which is very resistant to clostridial oncolysis in this mouse-tumour model, marked prolongations of survival or healing are possible even in extremely critical localization. In principle, this provides the preconditions for including oncolysis in clinical studies in human medicine. (orig./MG) [de

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.

    A recurrent paroxysmal presentation in children leads to different diagnoses and among them are neurologic and cardiac etiologies. Infantile masturbation is not a well known entity and cannot be differentiated easily from other disorders. Aim of this study is to elucidate and differentiate this condition from epileptic seizures. We report 3 cases of 10 to 30 mth old girls of infantile masturbation that their symptoms initiated at 2, 3 and 8 mth of age. These present with contraction and extension of lower extremities, scissoring of legs, perspiration, changing face color. In 2 cases body rocking and legs rubbing initiated then there after. Masturbation is one of the paroxysmal non-epileptic conditions of early infancy and is in differential diagnosis of epileptic seizures.

    In vivo studies were conducted to quantify the effectiveness of low-level direct electric current for different amounts of electrical charge and the survival rate in fibrosarcoma Sa-37 and Ehrlich tumors, also the effect of direct electric in Ehrlich tumor was evaluate through the measurements of tumor volume and the peritumoral and tumoral findings. BALB/c male mice, 7–8 week old and 20–22 g weight were used. Ehrlich and fibrosarcoma Sa-37 cell lines, growing in BALB/c mice. Solid and subcutaneous Ehrlich and fibrosarcoma Sa-37 tumors, located dorsolaterally in animals, were initiated by the inoculation of 5 × 10 6 and 1 × 10 5 viable tumor cells, respectively. For each type of tumor four groups (one control group and three treated groups) consisting of 10 mice randomly divided were formed. When the tumors reached approximately 0.5 cm 3 , four platinum electrodes were inserted into their bases. The electric charge delivered to the tumors was varied in the range of 5.5 to 110 C/cm 3 for a constant time of 45 minutes. An additional experiment was performed in BALB/c male mice bearing Ehrlich tumor to examine from a histolological point of view the effects of direct electric current. A control group and a treated group with 77 C/cm 3 (27.0 C in 0.35 cm 3 ) and 10 mA for 45 min were formed. In this experiment when the tumor volumes reached 0.35 cm 3 , two anodes and two cathodes were inserted into the base perpendicular to the tumor long axis. Significant tumor growth delay and survival rate were achieved after electrotherapy and both were dependent on direct electric current intensity, being more marked in fibrosarcoma Sa-37 tumor. Complete regressions for fibrosarcoma Sa-37 and Ehrlich tumors were observed for electrical charges of 80 and 92 C/cm 3 , respectively. Histopathological and peritumoral findings in Ehrlich tumor revealed in the treated group marked tumor necrosis, vascular congestion, peritumoral neutrophil infiltration, an acute inflammatory

    Full Text Available Hydroxybenzoate (HB compounds have shown to modulate the morphology in human fibrosarcoma HT-1080 cells. The changes in HT-1080 cells showed marker signs of apoptosis, which included the condensation of nucleus, cell round, blebbing and the formation of apoptotic bodies. The different stages of apoptosis were assessed microscopically using different staining and immunohistochemical techniques, as well as scanning electron microscopy. In addition, HB compounds increased the expression of caspase-3, which is closely associated with the development of the modulation in HT-1080 cells that are undergoing the programmed cell death. Both acetyl salicylic acid (ASA and HBZn compounds were dose and treatment duration dependent.

    Full Text Available Background: Few papers address the comprehensive prognosis in infantile spasms and look into the seizure profile and psychomotor outcome. Objective: We aimed to follow up children with infantile spasms to study: a the etiology, demographics, semiology, electroencephalogram (EEG, and radiological pattern; b seizure control, psychomotor development, and EEG resolution with treatment; c the effects of various factors on the control of spasms, resolution of EEG changes, and psychomotor development at 3-year follow-up. Materials and Methods: Fifty newly diagnosed cases with a 1-12 month age of onset and who had hypsarrhythmia in their EEG were recruited and 43 were followed up for 3 years. Results: Of the children followed up, 51% were seizure-free and 37% had a normal EEG at the 3-year follow-up. Autistic features were seen in 74% of the children. Only 22.7% among the seizure-free (11.6% of the total children had normal vision and hearing, speech with narration, writing skills, gross and fine motor development, and no autism or hyperactivity. On multivariate analysis, two factors could predict bad seizure outcome — the occurrence of other seizures in addition to infantile spasms and no response to 28 days of adrenocorticotropic hormone (ACTH. No predictor could be identified for abnormal psychomotor development. Discussion and Conclusion: In our study, we could demonstrate two factors that predict seizure freedom. The cognitive outcome and seizure control in this group of children are comparable to the existing literature. However, the cognitive outcome revealed by our study and the survey of the literature are discouraging.

    A 49-year old male was admitted with a history of radiotherapy for a pituitary adenoma 9 years earlier. Three weeks prior to admission, he noticed visual loss in the left eye. Computed tomography (CT) scan revealed a sellar tumor. The patient underwent craniotomy and the tumor was partially resected. The histological diagnosis was benign pituitary adenoma. Two months after surgery, he began to complain of headache and left hemiparesis. CT scan at that time showed a large parasellar tumor extending into the right temporal lobe. A second craniotomy was performed and a firm tumor was partially removed. Under light microscopy, the tumor was composed of anaplastic spindle cells showing a fascicular pattern. Ultrastructurally, the tumor cells were spindle-shaped with elongated nuclei. The cytoplasm contained numerous distended rough endoplasmic reticula and free ribosomes, Golgi apparatus as well as glycogen granules. Some desmosome-like intercellular adherents were observed. Collagen fibers were scattered in the extracellular space. There was no apparent formation of a basement membrane. These findings suggested a close morphological similarity between tumor cells and fibroblasts, conforming to ultrastructural diagnostic criteria for fibrosarcoma. In spite of intensive treatment, such as a second radiotherapy and subsequent craniotomy, the patient died 9 months after admission. The clinical course and pathological findings of the post-irradiation pituitary fibrosarcoma are discussed. (author).

  6. Enhanced metastatic potential of murine fibrosarcomas treated in vitro with ultraviolet radiation

    Fisher, M.S.; Cifone, M.A.

    1981-01-01

    The purpose of this study was to determine whether repeated treatment of tumor cells in vitro with mutagenic doses of ultraviolet (UV) radiation could influence the metastatic behavior of these cells in vivo. Three cloned lines of UV-2237, a fibrosarcoma induced in a C3H- mouse by chronic irradiation with UV, and SF-19, a spontaneous C3H- fibrosarcoma, were grown in culture. These cell lines varied from low to high metastatic potential as determined by in vivo tests. The cultures were exposed to UV radiation from an FS40 sunlamp at a dose that killed 40% of the cells. These UV radiation exposures were repeated at 3- to 5-day intervals for a total of 5 treatments. The mutation frequency was analyzed by monitoring the appearance of ouabain-resistant colonies following UV irradiation. With all four tumor lines, the frequency of conversion to ouabain resistance was increased more than 10-fold. Tumor cells given 5 UV radiation treatments and control cultures carried in parallel without exposure to UV radiation were tested for metastatic potential in an in vivo lung colony assay. Cell lines treated in vitro with UV radiation produced more experimental metastases than the counterpart unirradiated cultures. We conclude that, in all four tumor lines, exposure of tumorigenic cells to mutagenic doses of UV radiation can alter their biological behavior and that this may contribute to the progression of tumors from low to high metastatic capability

    In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type).

    In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type). The clinical, pathological and radiographical findings are reviewed

    Desmoplastic infantile ganglioglioma is an uncommon variety of ganglioglioma that shows evidence of glial and ganglionic differentiation accompanied by an extreme desmoplastic reaction. A 16-month-old girl was admitted with a six-day history of left hemiparesis. MR imaging demonstrated a large multiseptated cystic mass, with a solid portion, in the white matter of the right frontotemporoparietal lobe. After contrast injections, the solid portion was clearly enhanced. The presence of desmoplastic infantile ganglioglioma was confirmed by surgical resection. We describe the characteristic radiologic and pathologic features of desmoplastic infantile ganglioglioma, and include a review of the literature.

    Full Text Available Abstract Background Ovarian fibrosarcomas are very rare tumors, and therefore, few case studies have evaluated the prognostic factors of this disease. To our knowledge, this study represents the largest study to evaluate the clinical and pathologic factors associated with ovarian fibrosarcoma patients. Methods Thirty-one cases of ovarian fibrosarcoma were retrospectively reviewed, which included medical records for eight patients, and 23 published case reports from 1995 through 2009. Patient treatment regimens included total hysterectomy with bilateral adnexectomy and an omentectomy (BAO (n = 9, oophorectomy (OR (n = 8, chemotherapy (CT (n = 1, BAO followed by chemotherapy (BAO+CT (n = 11, BAO followed by radiotherapy (BAO+RT (n = 1, and oophorectomy followed by radiotherapy (OR + RT (n = 1. Results The patients of this cohort were staged according to the guidelines of the Federation of Gynecology and Obstetrics (FIGO, with 15, 6, 9, and 1 stage I-IV cases identified, respectively. Mitotic count values were also evaluated from 10 high-power fields (HPFs, and 3 cases had an average mitotic count P = 0.007 and treatment (P = 0.008 were predictive of poor prognosis. Furthermore, patients with stage I tumors that received BAO+CT were associated with a better prognosis. Conclusions Mitotic activity, and cells positive for Ki-67 were identified as important factors in the diagnosis of ovarian fibrosarcoma. Furthermore, FIGO stage and treatment modalities have the potential to be prognostic factors of survival, with BAO followed by adjuvant chemotherapy associated with an improved treatment outcome.

    Full Text Available Chronic renal insufficiency is a functional definition which is characterized by irreversible and progressive decreasing in renal functions. This impairment is in collaboration with glomeruler filtration rate and serum creatinine levels. Besides this, different grades of bone metabolism disorders develop in chronic renal insufficiency. Pathologic changes in bone tissue due to loss of renal paranchyme is interrelated with calcium, phosphorus vitamine-D and parathyroid hormone. Clinically we can see high turnover bone disease, low turnover bone disease, osteomalacia, osteosclerosis and osteoporosis in renal osteodystropy. In this article we aimed to review pathology of bone metabolism disorders due to chronic renal insufficiency, clinic aspects and treatment approaches briefly.

    The histological examination was carried out on the following 2 cases: One case was a 46-year-old man with psoriasis vulgaris who received x-ray irradiation continually for about 10 years on the gluteal regions and the extensive sides of both elbows. An ulcer appeared on the irradiated site and about 2 weeks later a tumor appeared. The other case was a 77-year-old man with prurigo in the pudendal region. Although the dose and duration of irradiation are unknown, the tumors appeared in the irradiated site 6-7 years after the start of irradiation. The histological examination of these cases revealed the clinical findings of fibrosarcoma. In the review of literature, 8 cases of irradiation sarcoma in Japan were discussed. (Kanao, N.)

    Chlorpromazine hydrochloride (CPZ) was shown to exhibit a definite cytotoxic effect on mice fibrosarcomas in vivo under both normal and acutely hypoxic conditions. Administration of the drug (20 or 40 mg/kg) before exposure to 20 Gy of x rays caused a greater delay in growth than in tumours irradiated without the drug; an equal amount of growth delay was found at both doses. The effect of the combined treatment was greater than the sum of the effects of the two treatments given individually. However, since an equal delay in tumour growth was caused by CPZ given before or after irradiation, the combined effect, although synergistic, could not be described as radiosensitization. (U.K.)

    A 33-year old female was seen in 1967 with about 3 year-history of diminution of visual acuity and amenorrhea, with abnormal gain of weight. At operation on April 19, 1967, typical pituitary adenoma was found and an intracapsular removal was performed. Histological sections showed a chromophobe adenoma without features of malignancy. Following operation, visual acuity and visual fields improved gradually to almost complete recovery. Radiotherapy was given with a tumor dose of 5,000 r. over a 6-week period. A second operation was done on November 29, 1973, and an intracapsular removal was repeated. The third operation on October 8, 1974 and the fourth operation on June 15, 1978 were done for saving sight, but in vain. Nevertheless, each operation showed extension of the tumor in the same way as in the previous observation. In April 1979, she was admitted by ambulance for dehydration and shock. She then developed swallowing disturbance, frontal headache and mental confusion. For the following 5 months, she had increasing deficits and subsequently developed dyspnea and left hemiparesis. Terminally, there was coma for a week. Postmortem examination disclosed neoplastic tissue, which not only filled a remarkably enlarged pituitary fossa but also extended downward as far as the mucosa of the oral cavity and upward into the frontal lobe. The optic nerves and 3rd nerves were almost obscured by the firm tumor. On slicing the brain coronally, this tumor was seen extending upward as far as the lateral ventricle. Microscopic examination showed a fibrosarcoma composed of elongated spindle cells. At the base of the tumor, islands of adenomatous tissue were present. The most likely causative factor in the development of pituitary fibrosarcoma in this patient is therapeutic radiation together with repeated surgical trauma. We would like to emphasize early awareness of such malignant alteration of clinical picture following radiation therapy. (J.P.N.)

    Post-translational regulation plays a critical role in the control of cell growth and proliferation. The phosphorylation of peroxisome proliferator-activated receptor γ (PPARγ) is the most important post-translational modification. The function of PPARγ phosphorylation has been studied extensively in the past. However, the relationship between phosphorylated PPARγ1 and tumors remains unclear. Here we investigated the role of PPARγ1 phosphorylation in human fibrosarcoma HT1080 cell line. Using the nonphosphorylation (Ser84 to alanine, S84A) and phosphorylation (Ser84 to aspartic acid, S84D) mutant of PPARγ1, the results suggested that phosphorylation attenuated PPARγ1 transcriptional activity. Meanwhile, we demonstrated that phosphorylated PPARγ1 promoted HT1080 cell proliferation and this effect was dependent on the regulation of cell cycle arrest. The mRNA levels of cyclin-dependent kinase inhibitor (CKI) p21{sup Waf1/Cip1} and p27{sup Kip1} descended in PPARγ1{sup S84D} stable HT1080 cell, whereas the expression of p18{sup INK4C} was not changed. Moreover, compared to the PPARγ1{sup S84A}, PPARγ1{sup S84D} up-regulated the expression levels of cyclin D1 and cyclin A. Finally, PPARγ1 phosphorylation reduced sensitivity to agonist rosiglitazone and increased resistance to anticancer drug 5-fluorouracil (5-FU) in HT1080 cell. Our findings establish PPARγ1 phosphorylation as a critical event in human fibrosarcoma growth. These findings raise the possibility that chemical compounds that prevent the phosphorylation of PPARγ1 could act as anticancer drugs. - Highlights: • Phosphorylation attenuates PPARγ1 transcriptional activity. • Phosphorylated PPARγ1 promotes HT1080 cells proliferation. • PPARγ1 phosphorylation regulates cell cycle by mediating expression of cell cycle regulators. • PPARγ1 phosphorylation reduces sensitivity to agonist and anticancer drug. • Our findings establish PPARγ1 phosphorylation as a critical event in HT1080

    Full Text Available Trabajo infantil e inasistencia escolar El capitalismo neoliberal ha generalizado la pobreza que obliga a muchas familias a recurrir al trabajo de los hijos para poder subsistir. Por el trabajo, los menores desertan de la escuela. Cuando adultos, por la pérdida en educación, sólo podrán acceder a las ocupaciones de menor calificación y peor pagadas. Por ello, tienen muchas probabilidades de ser los futuros padres de nuevos niños trabajadores reproduciendo intergeneracionalmente la pobreza. La educación es el primer paso para romper el círculo de la pobreza; hay relación entre los niveles de educación y las remuneraciones que las ersonas pueden alcanzar. El desarrollo descansa en el acelerado cambio tecnológico que no es más que el conocimiento científico aplicado a la producción. Crear conocimiento supone educación superior, y en la base de ésta está la educación básica, que es el cimiento de cualquier modelo de desarrollo que aspire a la equidad. No educar a los menores significa desperdiciar la formación de capital humano, ello traba el desarrollo nacional. Sin educación no habrá capital humano calificado como motor básico de la productividad y la competitividad.

  5. [Infantile autism and mirror neurons].

    2009-02-27

    Infantile autism is a disorder that is characterised by alterations affecting reciprocal social interactions, abnormal verbal and non-verbal communication, poor imaginative activity and a restricted repertoire of activities and interests. The causes of autism remain unknown, but there are a number of different approaches that attempt to explain the neurobiological causes of the syndrome. A recent theory that has been considered is that of a dysfunction in the mirror neuron system (MNS). The MNS is a neuronal complex, originally described in monkeys and also found in humans, that is related with our movements and which offers specific responses to the movements and intended movements of other subjects. This system is believed to underlie processes of imitation and our capacity to learn by imitation. It is also thought to play a role in language acquisition, in expressing the emotions, in understanding what is happening to others and in empathy. Because these functions are altered in children with autism, it has been suggested that there is some dysfunction present in the MNS of those with autism. Dysfunction of the MNS could account for the symptoms that are observed in children with autism.

    Aged garlic extract (AGE) has many biological activities including radical scavenging, antioxidative and immunomodulative effects. In this research work, the antitumor and immunomodulatory effects of AGE against fibrosarcoma implanted tumor were studied. WEHI-164 fibrosarcoma cells were implanted subcutaneously on day 0 into the right flank of 40 BALB/c mice at age of 8 weeks. Mice were randomly categorized in two separate groups: First received AGE (100 mg/kg, IP), second group as the control group received phosphate buffered saline. Treatments were carried out 3 times/week. Tumor growth was measured and morbidity was recorded. Subpopulations of CD4+/CD8+ T cells were determined using flow cytometry. WEHI-164 cell specific cytotoxicity of splenocytes and in vitro production of interferon gamma (IFN-γ) and interleukin-4 cytokines were measured. The mice received AGE had significantly longer survival time compared with the control mice. The inhibitory effect on tumor growth was seen in AGE treated mice. The CD4+/CD8+ ratio and in vitro IFN-γ production of splenocytes were significantly increased in AGE group. WEHI-164 specific cytotoxicity of splenocytes from AGE mice was also significantly increased at 25:1 E: T ratio. Administration of AGE resulted in improved immune responses against experimentally implanted fibrosarcoma tumors in BALB/c mice. AGE showed significant effects on inhibition of tumor growth and longevity of survival times.

    In ten patients with infantile spasms, brainstem evoked potentials and MRI examinations were performed to evaluate the brainstem involvement. The result of short latency somatosensory evoked potentials (SSEP) following the right median nerve stimulation revealed abnormal findings including the absence or low amplitudes of the waves below wave P3 and delayed central conduction time in 7 of the ten patients. The result of auditory brainstem responses (ABR) revealed abnormal findings including low amplitudes of wave V, prolonged interpeak latency of waves I-V and absence of the waves below wave IV in 5 of the ten patients. The result of the MRI examinations revealed various degrees of the brainstem atrophy in 6 of the ten patients, all of whom showed abnormal brainstem evoked potentials. The result of this study demonstrates that patients with infantile spasms are frequently associated with brainstem dysfunction and raises the possibility that brainstem atrophy might be a cause of infantile spasms.

The territorial fragility, that is exposed to the indigenous people in Argentina aremanifested daily in several areas. Mbyá population, has been crossed by the boundaries of national states of Paraguay, Brazil and Argentina. The sedentary and enclosures land processes in different states, have prompted changes in the logic of subsistence, housing and community organization. In Misiones province case, bureaucratic accreditation of land titles is postponed, the state is not committed to the realization of this right.RESUMEN: En este trabajo nos proponemos un acercamiento a las diversas ideas infantiles sobre el territorio habitado, en el contexto particular de la población mbyá guaraní de Misiones.

    Full Text Available Infantile hemangiomas (IHs are the most common benign soft tissue tumor of infancy and childhood. Many patients seek early treatment to halt progression of tumor growth and accelerate regression to achieve quick resolution with good cosmetic outcomes. We reviewed literature through PubMed search on the treatment strategies for IH and share our experience in the field of laser treatment of IH. Treatment strategies for IH include both pharmacological, laser, and surgical interventions depending on the stage and severity of the lesion. Various laser beams have been attempted with varying effects and effectiveness. The 595-nm pulsed dye laser therapy has been most widely utilized owing to its great efficacy but minimal adverse effects. It works by targeting oxyhemoglobin chromophore in blood vessels located within the dermis, causing photothermal damage of these target vessels stimulating quick involution without damaging surrounding healthy skin. It is especially useful in treating ulcerated superficial facial hemangiomas that necessitate rapid healing to avoid unsightly scarring. It has a good safety profile but small risk of epidermal burn, blistering, postinflammatory pigment changes, and scarring remains in those with darker skin types treated with higher fluences and short-pulsed duration. Combination treatment with 1064 nm neodymium-doped yttrium aluminum garnet laser, oral propranolol, and even corticosteroids remains an option, especially in treatment of deep, large, and functionally threatening IH. Careful consideration in consultation with the child's parents given the complexities and potential complications surrounding treatment should always be considered. Laser treatment remains an appropriate treatment for rapidly growing IH in exposed locations at early presentation.

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

    1997-01-01

    Purpose: Correct advance of cells through the S-phase of the mammalian cell cycle depends on the timely controlled activity of the E2F-1 transcription factor by cyclin A-cdk2. We are studying the reproductive integrity and radiosensitation of isogenic mouse fibrosarcoma cells, differing only in their p53 status, after expression of E2F-1 wildtype (wt) and specific E2F-1 mutants (mt) lacking the cyclin-A-binding domain. In this tumor model system only p53 wild-type expressing tumor cells are sensitive to ionizing radiation in vitro and in vivo. Material and Methods: Either wild-type p53 or genetically engineered p53 'null' mouse embryo fibroblasts were transfected with the oncogenes E1A and ras. These otherwise isogenic fibrosarcoma cells, with a malignant phenotype and tumorigenic in nude mice, were transfected with retroviruses containing either E2F-1 wild-type or specific E2F-1 mutants lacking the cyclin-A binding domain. Reproductive integrity after E2F-1 transfection with or without ionizing radiation (RT) was tested using the clonogenic assay. Tumor cell morphology of treated cells is analyzed for cell death mechanism. Results: E2F-1 wild-type expression in fibrosarcoma cells induced a clear p53 dependent cell death. While clonogenic survival of p53 'null' tumor cells was only slightly reduced with the expression of E2F-1 wild type (survival fraction of 0.5), the clonogenic survival of p53 wild-type fibrosarcoma tumor cells was reduced by at least one logarithm (survival fraction of 0.05). However, expression of the specific E2F-1 mutant lacking the cyclin-A binding domain reduced clonogenic survival in both the p53 'null' and the p53 wild-type fibrosarcoma cells by at least 2 logarithms (survival fraction 0.01 for p53 'null' and 0.002 for p53 wild-type). The mean values of the survival fractions after 2 and 5 Gy radiation alone in p53 'null' fibrosarcoma cells (SF 2 and SF 5) were SF 2 0.7, SF 5 = 0.15, respectively. The combination of ionizing RT in the p53

    The significance of time--dose ralationships in the use of local tumor hyperthermia (LTH) when combined with radiation (RAD) was studied in a murine fibrosarcoma. RAD, either alone or combined with LTH, was delivered in four equal fractions (total doses, 1.8 to 4.2 krad) separated by 1 to 4 days. LTH (43.1 C +- .05 C for 15 minutes, water bath) was applied immediately after RAD. In this tumor system, RAD was most effective when delivered every 2nd or 3rd day, by a factor of 1.25 over the response achieved when the four fractions were delivered every 1 or 4 days. At all levels studied, RAD + LTH produced a superior tumor response compared to RAD alone. The ratio of the RAD + LTH/RAD doses to achieve an isobiological response ranged from 1.7 to 2.5. Most significant was the finding that the RAD + LTH treatment response was independent of the fractionation scheme used and more dependent on the total RAD dose delivered

    Murine fibrosarcoma L929 cells have been used to test efficacy of proinflammatory cytokine TNFα. In the present study, we reported on protective effect of type I collagen gel used as L929 cell culture. L929 cell grew and proliferated well on collagen gel. However, the L929 cells exhibited cobblestone-like morphology which was much different from the spread fusiform shape when cultured on conventional cell dishes as well as the cells tended to aggregate. On conventional cell culture dishes, the cells treated with TNFα became round in shape and eventually died in a necroptotic manner. The cells cultured on collagen gel, however, were completely unaffected. TNFα treatment was reported to induce autophagy in L929 cells on the plastic dish, and therefore we investigated the effect of collagen gel on induction of autophagy. The results indicated that autophagy induced by TNFα treatment was much reduced when the cells were cultured on collagen gel. In conclusion, type I collagen gel protected L929 cell from TNFα-induced cell death. - Highlights: • Collagen gel culture changed the morphology of L929 cells. • L929 cell cultured on collagen gel were resistant to TNFα-induced cell death. • Collagen gel culture inhibited TNFα-induced autophagy in L929 cells

    Sarcomas are rare diseases of the head and neck region, representing around 1% of all malignancies. Amongst them, ameloblastic fibrosarcoma (AFS) is of even greater rarity, with less than 100 cases reported in the literature. Consequently, no standard treatment or guidelines have been made available. Surgery is often performed as primary therapy, but may be limited due to anatomical or functional reasons. We present a case of AFS successfully treated by postoperative radiation therapy. A detailed case study is provided, followed by a review of the English-language literature focusing on the role of radiation therapy. (orig.)

    Murine fibrosarcoma L929 cells have been used to test efficacy of proinflammatory cytokine TNFα. In the present study, we reported on protective effect of type I collagen gel used as L929 cell culture. L929 cell grew and proliferated well on collagen gel. However, the L929 cells exhibited cobblestone-like morphology which was much different from the spread fusiform shape when cultured on conventional cell dishes as well as the cells tended to aggregate. On conventional cell culture dishes, the cells treated with TNFα became round in shape and eventually died in a necroptotic manner. The cells cultured on collagen gel, however, were completely unaffected. TNFα treatment was reported to induce autophagy in L929 cells on the plastic dish, and therefore we investigated the effect of collagen gel on induction of autophagy. The results indicated that autophagy induced by TNFα treatment was much reduced when the cells were cultured on collagen gel. In conclusion, type I collagen gel protected L929 cell from TNFα-induced cell death. - Highlights: • Collagen gel culture changed the morphology of L929 cells. • L929 cell cultured on collagen gel were resistant to TNFα-induced cell death. • Collagen gel culture inhibited TNFα-induced autophagy in L929 cells.

    We sought to establish and characterize a mouse liver tumor model as a platform for preclinical assessment of new diagnostics and therapeutics. Radiation-induced fibrosarcoma (RIF-1) was intrahepatically implanted in 27 C3H/Km mice. Serial in vivo magnetic resonance imaging (MRI) with a clinical 1.5-T-magnet was performed using T1- (T1WI), T2- (T2WI), and diffusion-weighted sequences (DWI), dynamic contrast-enhanced MRI (DCE-MRI), and contrast-enhanced T1WI, and validated with postmortem microangiography and histopathology. Implantation procedure succeeded in 25 mice with 2 deaths from overdosed anesthesia or hypothermia. RIF-1 grew in 21 mice with volume doubling time of 2.55{+-}0.88 days and final size of 216.2{+-}150.4 mm{sup 3} at day 14. Three mice were found without tumor growth and one only with abdominal seeding. The intrahepatic RIF-1 was hypervascularized with negligible necrosis as shown on MRI, microangiography and histology. On DCE-MRI, maximal initial slope of contrast-time curve and volume transfer constant per unit volume of tissue, K, differed between the tumor and liver with only the former significantly lower in the tumor than in the liver (P<0.05). Liver implantation of RIF-1 in mice proves a feasible and reproducible model and appears promising for use to screen new diagnostics and therapeutics under noninvasive monitoring even with a clinical MRI system.

    Full Text Available A 60-year-old lady presented to us with a right upper abdominal mass. With a clinical diagnosis of liver tumor, she was evaluated with abdominal CT, MRI, nuclear scan, tumor markers, USG guided FNAC and other baseline investigations. On evaluation she had a massive right lobe tumor crossing the midline. In view of the ambiguous diagnosis she was subjected to laparotomy where the lesion was judged unresectable and a biopsy was taken. Histopathological examination showed the rare pathology of primary fibrosarcoma of the liver with features of homogeneous, spindle-shaped cells with abundant collagen fibers showing a classic herringbone pattern. Tissue samples were then sent to another referral cancer hospital for immunohistochemistry and immunoreactive vimentin was found in the tumor cells. Electron microscopically, the tumor cells were rich in rough endoplasmic reticulum without a basement membrane, and were surrounded by large amounts of collagen fibers. The fibroblastic character of the tumor cells was suggested by light and electron microscopy.

    Balb/c mice bearing a methylcholanthrene-induced fibrosarcoma were used to compare the activation levels of tumor-associated and peritoneal macrophages. Two stages of tumor growth were examined, namely "small" and "large" tumors, with average diameters of 10 and 30 mm, respectively. The activation state, determined by measurement of both phagocytic index and beta-glucuronidase content, was found to be markedly higher in tumor-associated macrophages than in their peritoneal counterparts and it was, in addition, independent of tumor progression. The percentage of tumor-associated macrophages, which were detected on the basis of Fc receptor expression, remained constant in the growing neoplasm, at approximately 23% of total cell population. None of these parameters were affected by inoculation with an immunopotentiating dose of heat-killed Candida albicans which, on the other hand, seemed not to alter the course of the tumor. These data suggest that within the tumor microenvironment macrophages would somehow be maintained at a constant proportion and at a highly activated state, while outside the tumor they would be at a lower activation level. Our results also suggest that TAM would not possess antitumor activity in vivo, although we have found this activity in vitro.

    Full Text Available Saud Alarifi, Daoud Ali, Saad Alkahtani Department of Zoology, College of Science, King Saud University, Riyadh, Saudi Arabia Abstract: Chromium oxide nanoparticles (Cr2O3NPs are widely used in polymers and paints. In the present study, we aimed to determine the toxicity of Cr2O3NPs in murine fibrosarcoma (L929 cells. The cytotoxicity of Cr2O3NPs was measured by MTT and neutral red uptake assays; Cr2O3NPs had significant cytotoxic effects on L929 cells. Enhancement of intracellular reactive oxygen species was observed in L929 cells after exposure to Cr2O3NPs. Cr2O3NPs produced caspase-3, indicating that exposure to Cr2O3NPs induced apoptosis. After exposure to Cr2O3NPs, the cellular glutathione level decreased and lipid peroxidation, superoxide dismutase, and catalase increased in a dose- and time-dependent manner. By using single-cell gel tests, we also observed increased DNA damage in a Cr2O3NP exposure-duration- and dose-dependent fashion. Cell toxicity and DNA damage may be useful biomarkers for determining the safety of Cr2O3NPs in human and animal health. Keywords: Cr2O3NPs, L929 cells, MTT assay, oxidative stress

    Fibrosarcoma (FS) is a malignant mesenchymal neoplasm of the fibroblasts that rarely affects the oral cavity. Two cases of primary FS of the jaws with intraosseous growth (2 men, aged 53 and 71 years) are described. Microscopically, in one case the tumor showed an intense proliferation of spindle-shaped cells, varying little in size and shape and arranged in parallel bands, partly crossing each other, with significant mitotic activity and nuclear pleomorphism; the second case was characterized by low cellularity comprising spindle-shaped cells, deposited in a variably fibrous and myxoid stroma. On immunohistochemistry, cells in both cases were strongly immunoreactive for MIB-1 and vimentin, focally positive for CD68, and negative for S-100 protein, pancytokeratin, HMB45, CD34, desmin, smooth muscle actin (SMA) and epithelial membrane antigen (EMA). Based on clinical, histological and immunohistochemical findings, the final diagnosis was FS in the first case, myxofibrosarcoma in the second. Treatment was radical surgery with mandibular reconstruction. After two years, the first patient displayed multiple metastases and died during the third year after the initial diagnosis; the second patient was still alive and doing well five years after treatment. We discuss the differential diagnosis versus other forms of sarcoma, examining the morphological appearance that is frequently very similar, the immunohistochemical expression of MIB-1, vimentin, S-100, CD-34, CD68, EMA, as well as conventional clinicopathological features that may help to distinguish FS from other sarcomas.

  4. Influencing the radiosensitivity of a transplantable fibrosarcoma by synchronisation with hydroxyurea

    Kummermehr, J.; Trott, K.R.

    1979-01-01

    Due to its specific S-phase-toxicity and the blocking effect in G 1 /S-transition, hydroxy urea seems to be particularly suitable for testing the possible use of a synchronisation therapy in animal experiments. The injection of 0,5 mg/g, repeated four times, in a transplantable fibrosarcoma of a mouse, caused the accumulation of 70% of the surviving proliferating cells in the radio-sensitive G 1 /S-phase. A slight sensitization, corresponding to a dose modification factor of 1,3, could be manifested compared with a single dose of 600 rd. but not with higher doses. This effect could partly be repeated in franctionated treatment with 2 x 600 rd at 2-day internals. With other intervals and with an extension to triple-fractionated-synchronisation treatment, the total outcome was negative. Due to these results and the situation of human solid tumors which is, cell-kinetically, considerably less favourable, a combined clinical treatment on the basis of synchronisation seems hardly promising.

    A C3H fibrosarcoma was synchronized by an injection schedule of hydroxyurea adjusted to its proliferation kinetics. By imposing an 8 h block, 70% of the proliferating non-S-phase cells were accumulated and entered the S-phase synchronously between 2 and 3 h after the last injection. Progression of S-phase cells exposed to hydroxyurea was severely disturbed whereas progression of the synchronized population was nearly normal. Tumours were given a local irradiation with single doses of 300kV X-rays either 2 h after the last hydroxyurea injection, when the synchronized population was still at the G 1 /S-border, or 6 h after the last injection, when cells had proceeded into mid S-phase. Doses ranged from 600 rad to 2400 rad and were given under ambient or hypoxic conditions. The tumour volume was measured at regular intervals. The median regrowth delay of tumours irradiated in air without hydroxyurea displayed a typical biphasic dose/response curve. Tumours irradiated 6 h after hydroxyurea injection showed the same response. For tumours irradiated 2 h after hydroxyurea injection, a significant increase in delay time was found after 600 rad had been given in air, but not after higher doses. A similar sensitizing effect could be detected after 2400 rad had been given under hypoxic conditions. The sensitizing effect of synchronization could be repeated 2 days after a first dose of 600 rad but not after 3 or 4 days. Repeating the synchronization and 600 rad irradiation schedule three times was less effective than irradiating with 3 fractions of 600 rad in 4 days. (author)

    Nanoparticles are prevalent in both commercial and medicinal products; however, the contribution of nanomaterials to carcinogenesis remains unclear. We therefore examined the effects of nano-sized titanium dioxide (TiO(2)) on poorly tumorigenic and nonmetastatic QR-32 fibrosarcoma cells. We found that mice that were cotransplanted subcutaneously with QR-32 cells and nano-sized TiO(2), either uncoated (TiO(2)-1, hydrophilic) or coated with stearic acid (TiO(2)-2, hydrophobic), did not form tumors. However, QR-32 cells became tumorigenic after injection into sites previously implanted with TiO(2)-1, but not TiO(2)-2, and these developing tumors acquired metastatic phenotypes. No differences were observed either histologically or in inflammatory cytokine mRNA expression between TiO(2)-1 and TiO(2)-2 treatments. However, TiO(2)-2, but not TiO(2)-1, generated high levels of reactive oxygen species (ROS) in cell-free conditions. Although both TiO(2)-1 and TiO(2)-2 resulted in intracellular ROS formation, TiO(2)-2 elicited a stronger response, resulting in cytotoxicity to the QR-32 cells. Moreover, TiO(2)-2, but not TiO(2)-1, led to the development of nuclear interstices and multinucleate cells. Cells that survived the TiO(2) toxicity acquired a tumorigenic phenotype. TiO(2)-induced ROS formation and its related cell injury were inhibited by the addition of antioxidant N-acetyl-l-cysteine. These results indicate that nano-sized TiO(2) has the potential to convert benign tumor cells into malignant ones through the generation of ROS in the target cells.

    Full Text Available Introduction: Garlic has been demonstrated to have anticancer activity in some studies; however its effect on fibrosarcoma is not evident. This study intends to examine the preventive and curative effects of fresh garlic extract and its aerial parts on the growth of WEHI-164 fibrosarcoma cells in Balb/c mice. Methods: In this preclinical study, 48 female inbred Balb/c mice(6 to 7 weeks old were divided in to 6 groups of 8 each. A single aliquot of WEHI-164 cells(5 × 106 cells/100 μl was injected subcutaneously in the chest of animal. Two weeks before or three weeks after cell injection, 0.2 cc of normal saline or 20 mg/kg extract of garlic or its aerial parts were injected intraperitoneally(IP to the Balb/c mice. The tumors sizes were compared with each other, using ANOVA test. The antioxidant potential and total phenolic compounds of the extracts were also assessed. Results: The mean sizes of tumor growth in groups which received fresh garlic extract or its aerial parts were smaller than that of control group. However this difference was significant on the 21st day only in garlic extract group(p<0.05. The antioxidant power of fresh garlic involved 35.6%, whereas for its aerial parts it was 15.3%. Moreover, the general amount of phenol in fresh garlic was 12.61 mg/g and in its aerial parts was 2.44 mg/g. Conclusion: Garlic consumption might have a crucial role in prevention and control of fibrosarcoma growth. Furthermore, the phenolic compounds and antioxidant activity of garlic aerial parts are less in comparison to garlic itself, however, higher doses might have anticancer activity

    Full Text Available Ameloblastic fibrosarcoma (AFS is a rare malignant mixed odontogenic tumor which is usually considered as the malignant counterpart of ameloblastic fibroma. Only mesenchymal component represents sarcomatous alterations and ameloblast-like epithelial nest remains bland in AFS. Here, we report a case of AFS in a 26-year-old man in the maxilla, which was regarded as an uncommon location for this tumor. After 2 years follow up, no evidence of recurrence was noted. We also emphasize on comprehensive clinical, radiographic, and histopathologic evaluation of such patients rather than immunohistochemical staining to make an accurate diagnosis.

    Dermato-fibrosarcoma protuberans is a low incidence skin neoplasia of difficult management due to its high recurrence rate. Usual treatment consists of a large resection, some times causing functional and aesthetics impairment, and despite these efforts, published data point to a recurrence rate of 11% to 53%. Recently, radiotherapy has been used modifying the unreal course of this tumor, decreasing drastically the recurrence rate when compared to surgery only. We reviewed these treatment modalities and related three cases of large recurrent tumors treated in our plastic surgery department with surgery and adjuvant radiotherapy, without recurrences after 2 years follow up.

    Full Text Available The study aimed to demonstrate the expression of hypoxia-inducible factor (HIF-1α in soft tissue mesenchymal tumours (fibroma and fibrosarcoma in dogs. An attempt was made to correlate the obtained results with density of blood vessels (expression of von Willebrand Factor, vWF, expression of Ki-67 proliferation antigen, and with intensity of apoptosis in studied tumours. The study was performed on paraffin sections of 15 fibromas and 40 fibrosarcomas sampled from 55 female dogs aged 6 to 16 years. Immunohistochemical staining against HIF-1α, vWF, and Ki-67 was performed. Apoptosis was detected with the use of TUNEL reaction. A significantly higher HIF-1α expression was noted in fibrosarcomas in comparison to fibromas (P < 0.0001. HIF-1α expression in fibromas manifested strong positive correlation with tumour vascularity (r = 0.67, P = 0.007. Moreover, HIF-1α expression in fibrosarcomas manifested a moderate positive correlation with tumour malignancy grade (r = 0.44, P = 0.004, tumour vascularity (r = 0.52, P < 0.001, Ki-67 antigen expression (r = 0.42; P = 0.007, and TUNELpositive cells (r = 0.37, P = 0.017. Expression of HIF-1α was detected in 86.7% of fibroma type tumours and in 100% of fibrosarcomas. In all studied tumours expression of HIF-1α manifested positive correlation with the density of blood vessels, and in fibrosarcomas it correlated also with malignancy grade, intensity of Ki-67 expression, and with intensity of apoptosis in tumour cells.

    Full Text Available Infantile hemangiomas (IH are common vascular tumours. IH have a characteristic natural course. They proliferate rapidly during the early infantile period followed by a period of gradual regression over several years. Most of the uncomplicated IH undergo spontaneous involution, with a small proportion of cases requiring intervention. These are children with IH in life-threatening locations, local complications like haemorrhage, ulceration and necrosis and functional or cosmetic disfigurements. Systemic corticosteroids have been the first line of treatment for many years. Recently, non-selective beta-blockers, such as oral propranalol and topical timolol, have emerged as promising and safer therapies. Other treatment options include interferon α and vincristine which are reserved for life-threatening haemangiomas that are unresponsive to conventional therapy. This review mainly focuses on the current trends and evidence-based approach in the management of IH.

We investigated whether targeting of HIF-1 using chetomin, a disrupter of the interaction of HIF-1 with the transcriptional coactivator p300, influences the radiosensitivity of hypoxic HT 1080 human fibrosarcoma cells. Optimal dose of chetomin was determined by EGFP-HRE gene reporter assay in stably transfected HT 1080 cells. Cells were assayed for expression of the hypoxia-inducible genes carbonic anhydrase 9 (CA9) and vascular endothelial growth factor (VEGF) by RT-PCR and for clonogenic survival after irradiation with 2, 5 or 10 Gy, under normoxic or hypoxic (0.1% O 2 , 12 h) conditions in the presence or absence of chetomin (150 nM, 12 h, pre-treatment of 4 h). Chetomin treatment significantly reduced CA9 and VEGF mRNA expression in hypoxic cells to 44.4 ± 7.2% and 39.6 ± 16.0%, respectively, of untreated hypoxic controls. Chetomin clearly reduced the modified oxygen enhancement ratio (OER') compared to untreated cells, from 2.02 to 1.27, from 1.86 to 1.22 and from 1.49 to 1.06 at the 50%, 37% and 10% clonogenic survival levels, respectively. HIF-1 inhibition by chetomin effectively reduces hypoxia-dependent transcription and radiosensitizes hypoxic HT 1080 human fibrosarcoma cells in vitro

    Full Text Available Proteomic analyses are rapid and powerful tools that are used to increase the understanding of cancer pathogenesis, discover cancer biomarkers and predictive markers, and select and monitor novel targets for cancer therapy. Feline injection-site sarcomas (FISS are aggressive skin tumours with high recurrence rates, despite treatment with surgery, radiotherapy, and chemotherapy. Doxorubicin is a drug of choice for soft tissue sarcomas, including FISS. However, multidrug resistance is one of the major causes of chemotherapy failure. The main aim of the present study was to identify proteins that differentiate doxorubicin-resistant from doxorubicin-sensitive FISS using two-dimensional gel electrophoresis (2DE, followed by matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS analysis. Using the three-dimensional (3D preclinical in ovo model, which resembles features of spontaneous fibrosarcomas, three significantly (p ≤ 0.05 differentially expressed proteins were identified in tumours grown from doxorubicin-resistant fibrosarcoma cell lines (FFS1 and FFS3 in comparison to the doxorubicin-sensitive one (FFS5: Annexin A5 (ANXA5, Annexin A3 (ANXA3, and meiosis-specific nuclear structural protein 1 (MNS1. Moreover, nine other proteins were significantly differentially expressed in tumours grown from the high doxorubicin-resistant cell line (FFS1 in comparison to sensitive one (FFS5. This study may be the first proteomic fingerprinting of FISS reported, identifying potential candidates for specific predictive biomarkers and research targets for doxorubicin-resistant FISS.

    OBJECTIVE: GM2 gangliosidoses are caused by an inherited deficiency of lysosomal β-hexosaminidase and result in ganglioside accumulation in the brain. Onset during infancy leads to rapid neurodegeneration and death before 4 years of age. We set out to quantify the rate of functional decline in infantile GM2 gangliosidosis on the basis of patient surveys and a comprehensive review of existing literature. METHODS: Patients with infantile GM2 gangliosidosis (N = 237) were surveyed via questionnaire by the National Tay Sachs & Allied Diseases Association (NTSAD). These data were supplemented by survival data from the NTSAD database and a literature survey. Detailed retrospective surveys from 97 patients were available. Five patients who had received hematopoietic stem cell transplantation were evaluated separately. The mortality rate of the remaining 92 patients was comparable to that of the 103 patients from the NTSAD database and 121 patients reported in the literature. RESULTS: Common symptoms at onset were developmental arrest (83%), startling (65%), and hypotonia (60%). All 55 patients who had learned to sit without support lost that ability within 1 year. Individual functional measures correlated with each other but not with survival. Gastric tube placement was associated with prolonged survival. Tay Sachs and Sandhoff variants did not differ. Hematopoietic stem cell transplantation was not associated with prolonged survival. CONCLUSIONS: We studied the timing of regression in 97 cases of infantile GM2 gangliosidosis and conclude that clinical disease progression does not correlate with survival, likely because of the impact of improved supportive care over time. However, functional measures are quantifiable and can inform power calculations and study design of future interventions. PMID:22025593

  8. Disruption of chromosome 11 in canine fibrosarcomas highlights an unusual variability of CDKN2B in dogs

    Full Text Available Abstract Background In dogs in the western world neoplasia constitutes the most frequently diagnosed cause of death. Although there appear to be similarities between canine and human cancers, rather little is known about the cytogenetic and molecular alterations in canine tumours. Different dog breeds are susceptible to different types of cancer, but the genetic basis of the great majority of these predispositions has yet to be discovered. In some retriever breeds there is a high incidence of soft tissue sarcomas and we have previously reported alterations of chromosomes 11 and 30 in two poorly differentiated fibrosarcomas. Here we extend our observations and present a case report on detail rearrangements on chromosome 11 as well as genetic variations in a tumour suppressor gene in normal dogs. Results BAC hybridisations on metaphases of two fibrosarcomas showed complex rearrangements on chromosome 11, and loss of parts of this chromosome. Microsatellite markers on a paired tumour and blood DNA pointed to loss of heterozygosity on chromosome 11 in the CDKN2B-CDKN2A tumour suppressor gene cluster region. PCR and sequencing revealed the homozygous loss of coding sequences for these genes, except for exon 1β of CDKN2A, which codes for the N-terminus of p14ARF. For CDKN2B exon 1, two alleles were observed in DNA from blood; one of them identical to the sequence in the dog reference genome and containing 4 copies of a 12 bp repeat found only in the canine gene amongst all species so far sequenced; the other allele was shorter due to a missing copy of the repeat. Sequencing of this exon in 141 dogs from 18 different breeds revealed a polymorphic region involving a GGC triplet repeat and a GGGGACGGCGGC repeat. Seven alleles were recorded and sixteen of the eighteen breeds showed heterozygosity. Conclusion Complex chromosome rearrangements were observed on chromosome 11 in two Labrador retriever fibrosarcomas. The chromosome alterations were reflected

    Full Text Available Sclerosing epithelioid fibrosarcoma (SEF is a rare soft tissue sarcoma mostly occurring in extraosseous sites. SEF represents a clinically challenging entity especially because no standardized treatment regimens are available. Intraosseous localization is an additional challenge with respect to the therapeutical approach. We report on a 16-year-old patient with SEF of the right proximal tibia. The patient underwent standardized neoadjuvant chemotherapy analogous to the EURAMOS-1 protocol for the treatment of osteosarcoma followed by tumor resection and endoprosthetic reconstruction. Histopathological analysis of the resected tumor showed >90% vital tumor cells suggesting no response to chemotherapy. Therefore, therapy was reassigned to the CWS 2002 High-Risk protocol for the treatment of soft tissue sarcoma. To date (22 months after diagnosis, there is no evidence of relapse or metastasis. Our data suggest that SEF may be resistant to a chemotherapy regimen containing Cisplatin, Doxorubicin, and Methotrexate, which should be considered in planning treatment for patients with SEF.

    Little has been published on gratification disorder ("infantile masturbation") in early childhood. To expand on the profile of patients diagnosed with this condition. Retrospective case note review; Fraser of Allander Neurosciences Unit paediatric neurology outpatient department 1972-2002. 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. 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.

    Thiamine deficiency in infants is still encountered in developing countries. It may present with acute neurological manifestations of infantile encephalitic beriberi. To review brain MRI findings in infantile encephalitic beriberi from a single institution. A retrospective review of MRI scans in 22 infants with acute-onset beriberi encephalopathy was carried out. Hyperintense lesions on T2-weighted images were seen symmetrically in the putamen in all patients, in the caudate nuclei in 16/22 (73%), the thalami in 7/22 (32%) and the globi pallidi in 3/22 (14%) of the infants. Altered signal intensity lesions in the cerebral cortex were seen in 7/22 (32%). The mammillary bodies were seen in one infant and the periaqueductal gray matter in two. There was restricted diffusion in 14/22 (64%), and 6/8 children with no evidence of restriction had been imaged ≥10 days after presentation. MR spectroscopy showed increased lactate peak in 6/8 infants (75%). Recognition of symmetrical T2-W hyperintense lesions in the basal ganglia with restricted diffusion and prominent lactate peak may allow early diagnosis of encephalitic beriberi in at-risk infants.

    Out of 109 children with infantile spasms (IS), prospectively tested during the years 1976 to 1979 in Denmark, 52 children were examined by cranial computed tomography (CT). The classification of IS into cryptogenic (CR), symptomatic (SY) and doubtful (DO) was done clinically without considering the CT-finding. Sixty per cent of the scannings were abnormal. Only 6/30 (20%) of the children in ACTH treatment were found to develop cerebral atrophy which means that this finding is not an obligatory side-effect of ACTH treatment of children with IS. Normal CT-findings were found in 50% of the CR and 50% of the SY + DO-groups, and could not be used as a prognostic tool for estimating the mental development. This was also the case for children with cerebral atrophy. Abnormal CT-findings (minus atrophy) were highly correlated to the group with clinical symptoms and indicate an extremely unsatisfying long-term mental prognosis. CT-scanning is a valuable tool for the examination of clearing children with infantile spasms. (authors)

    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.

    Infantile hemangiomas are the most common vascular tumors of infancy. A multidisciplinary approach including dermatologists, otolaryngologists, plastic surgeons, hematologists/oncologists and interventional/diagnostic radiologists is crucial for appropriate management of children with complicated infantile hemangiomas. Since its unforeseen discovery in 2008, propranolol has become the first-line treatment for infantile hemangiomas, eclipsing systemic corticosteroids and radiologic intervention. There are still, however, uncommon indications for more aggressive interventional management. We review the 2014-updated International Society for the Study of Vascular Anomalies (ISSVA) classification for vascular anomalies. Additionally, we suggest management algorithms for complicated lesions, including recommendations for radiologic and surgical intervention. (orig.)

    Full Text Available INTRODUCTION: Renal hemangioma is a relatively rare benign tumor, seldom diagnosed as a cause of hematuria. CASE REPORT: A female 40-year old patient presented with continuous gross hematuria, anemia and episodic right lumbar pain, with onset about 3 months previously. The patient underwent multiple blood transfusions during her hospital stay and extensive imaging propedeutics was performed. Semi-rigid ureterorenoscopy evidenced a bleeding focus in the upper calix of the right kidney, with endoscopic treatment being unfeasible. The patient underwent right upper pole nephrectomy and presented a favorable outcome. Histopathological analysis of the surgical specimen showed that it was a renal hemangioma. COMMENTS: Imaging methods usually employed for diagnostic investigation of hematuria do not have good sensitivity for renal hemangioma. However, they are important to exclude the most frequent differential diagnoses. The ureterorenoscopy is the diagnostic method of choice and endoscopic treatment can be feasible when the lesion is accessible and electrocautery or laser are available. We emphasize the open surgical treatment as a therapeutic option upon failure of less invasive methods.

    Cranial CT scanning was undertaken in 40 patients with infantile viral encephalitis seen from 1977 to 1983. According to the pathogenic viruses, abnormal CT findings were detected most frequently in cases of herpes simplex encephalitis (HSE), followed by non-eruptive viral encephalitis, measles encephalitis, and rubella encephalitis in that order, which coincided well with neurological prognosis. Although CT findings lay within a normal range in cases of measles encephalitis, except a case in which cerebral ventricle was slightly dilated, the degree of consciousness disturbance was unfavorable and it persisted long. This revealed that there is no distinct correlation between the degree of consciousness disturbance and CT findings. Normal CT findings were detected in 13% of patients aged less than 5 years and 76.5% of patients aged 5 years or more. In many patients who had an attack of viral encephalitis at the age of 5 years or more, epileptic seizures occurred frequently, even though CT findings were normal. (Namekawa, K.)

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    1979-01-01

    Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The earliest major planned operations were for the removal of vesical calculus; renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman; but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Professor Pyrah has had a long an...

    A TAT47-57 peptide was modified on the N-terminus by elongation with a 2,3-diaminopropionic acid residue and then by coupling of two histidine residues on its N-atoms. This branched peptide could bind to Ni under physiological conditions as a 1 : 1 complex. We demonstrated that the complex was quantitatively taken up by human fibrosarcoma cells, in contrast to Ni(2+) ions. Ni localization (especially at the nuclei) was confirmed by imaging using both scanning X-ray fluorescence microscopy and Newport Green fluorescence. A competitive assay with Newport Green showed that the latter displaced the peptide ligand from the Ni-complex. Ni(2+) delivered as a complex with the designed peptide induced substantially more DNA damage than when introduced as a free ion. The availability of such a construct opens up the way to investigate the importance of the nucleus as a target for the cytotoxicity, genotoxicity or carcinogenicity of Ni(2+).

    1985-01-01

    Glycosaminoglycan synthesis was studied in cell populations of ultraviolet light-induced murine cutaneous fibrosarcoma cells under conditions of varying growth rates in vitro. After labeling with the precursors, 3 H-glucosamine and 35 SO 4 , sulfated glycosaminoglycans recoverable by direct proteolysis of the culture monolayers increased approximately 5-fold on a per cell basis from sparsely populated, exponential cell cultures (greater than 85% of cells in S, G2, or M phases) to stationary cultures inhibited by high cell density (greater than 50% of cells in G1). Within this cell surface-associated material, the relative ratio of heparan sulfate to the chondroitin sulfates was approximately 60/40% under conditions of exponential growth; in the growth-arrested cultures, the reverse ratio was found. The substratum attached material, obtained from the flask surface after ethyl glycol bis(beta-aminoethyl ether)-N,N'-tetraacetic acid (EGTA)-mediated detachment of the monolayers, contained relatively more hyaluronic acid, heparan sulfate, and chondroitin sulfates in the most actively proliferating cultures compared with the growth-inhibited cell populations. Furthermore, heparan sulfate and the chondroitin sulfates, which were enriched in the substratum material and in the cell pellet of exponential cultures, showed a relative shift to the cell surface-associated compartment (releasable by mild trypsinization after EGTA-mediated cell detachment) and to the compartment loosely associated with the pericellular matrix (i.e., released into the supernatant during detachment of the monolayers in the presence of EGTA)

    To describe imaging features of infratentorial desmoplastic infantile or non-infantile tumors (DIT/DNIT). Four cases with infratentorial DIT/DNIT from our hospital and 5 cases from literature review were analyzed. Clinical data and MR imaging features were evaluated including location, size, shape, margin, composition, dural attachment, perilesional edema, and metastasis or multiplicity. The mean age was 9.2 years (range, 1-18 years). Most of the patients presented with headache or vomiting (4/9, 44.4%) and had no underlying disease (8/9, 88.9%). The major pathologic subtype was astrocytoma (6/9, 66.7%). On MR, majority of the tumors involved cerebellum and/or spinal cord (8/9, 88.9%) and the mean size of the tumors was 4.2 cm (range, 3.2-5 cm). The tumors were mainly solid (4/9, 44.4%) or mixed (4/9, 44.4%) in composition with lobulated shape (7/9, 77.8%) and well-defined margin (7/9, 77.8%). Two cases (2/7, 28.6%) showed dural attachment and all the cases had no or minimal perilesional edema (100%). Metastasis or multiplicity was frequently seen in 44.4% (4/9). Infratentorial DIT/DNIT occurred in relatively older children and the major tumor type was astrocytoma. They also had atypical imaging features showing mainly solid or mixed in composition with frequent metastasis or multiplicity.

    Infantile strabismus is characterized by numerous visual and oculomotor abnormalities. Recently nonhuman primate models of infantile strabismus have been established, with characteristics that closely match those observed in human patients. This has made it possible to study the neural basis for visual and oculomotor symptoms in infantile strabismus. In this review, we consider the available evidence for neural abnormalities in structures related to oculomotor pathways ranging from visual cortex to oculomotor nuclei. These studies provide compelling evidence that a disturbance of binocular vision during a sensitive period early in life, whatever the cause, results in a cascade of abnormalities through numerous brain areas involved in visual functions and eye movements.

    Full Text Available OBJETIVO: Analisar os significados culturais da asma infantil com origem na mãe-cuidadora. PROCEDIMENTOS METODOLÓGICOS: Pesquisa qualitativa realizada em 2004, no município de Fortaleza, CE. Foi utilizada a observação participante com abordagem etnográfica e entrevistas com sete mães acompanhantes de seus filhos em unidade de emergência hospitalar. Os significados das falas das mães foram identificados utilizando-se a técnica de análise temática. ANÁLISE DOS RESULTADOS: Foram identificadas duas categorias de discussão; na primeira, "desinformação sobre a doença", foi possível perceber que as mães não são informadas sobre a doença do filho. Na segunda categoria, "cuidado cultural", as mães referem informações sobre os cuidados e utilizam recursos do saber popular para prevenir a asma dos filhos, como o cuidado ambiental e a utilização de remédios caseiros à base de plantas medicinais. CONCLUSÕES: As características de desinformação e desconhecimento materno em relação à asma do filho mostram a necessidade de haver um trabalho educativo intenso, dialógico e problematizador em estreita colaboração com o tratamento, visando à melhoria do prognóstico da doença.OBJECTIVE: To analyze the cultural meanings of infantile asthma from the perspective of the mother/carer of the child. METHODOLOGICAL PROCEDURES: Qualitative research conducted in 2004, in the city of Fortaleza (Northeastern Brazil. An ethnographic approach was utilized, consisting of participant observation and interviews with seven mothers, accompanying their children in a hospital emergency ward. Thematic analysis was the technique employed when identifying the meanings of mothers' discourse. ANALYSIS OF RESULTS: Two discussion categories were identified: "disinformation on illness" in which it was possible to perceive that the mothers were not informed with respect to their children's illness; and "cultural care" in which they relate information on

    Infantile haemangiomas (previously known as strawberry birthmarks) are soft, raised swellings of the skin that occur in 3% to 10% of infants. These benign vascular tumours are usually uncomplicated and tend to regress spontaneously. However, when haemangiomas occur in high-risk areas, such as near the eyes, throat, or nose, impairing their function, or when complications develop, intervention may be necessary. This is an update of a Cochrane Review first published in 2011. To assess the effects of interventions for the management of infantile haemangiomas in children. We updated our searches of the following databases to February 2017: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, AMED, LILACS, and CINAHL. We also searched five trials registries and checked the reference lists of included studies for further references to relevant trials. Randomised controlled trials (RCTs) of all types of interventions, versus placebo, active monitoring, or other interventions, in any child with single or multiple infantile haemangiomas (IHs) located on the skin. We used standard methodological procedures expected by Cochrane. The primary outcome measures were clearance, a subjective measure of improvement, and adverse events. Secondary outcomes were other measures of resolution; proportion of parents or children who consider there is still a problem; aesthetic appearance; and requirement for surgical correction. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. We included 28 RCTs, with a total of 1728 participants, assessing 12 different interventions, including lasers, beta blockers (e.g. propranolol, timolol maleate), radiation therapy, and steroids. Comparators included placebo, an active monitoring approach, sham radiation, and interventions given alone or in combination.Studies were conducted in a number of countries, including China, Egypt, France, and Australia.

    Full Text Available De 1959 a 1999, con los datos estadísticos disponibles, la mortalidad infantil en Cuba disminuyó en 81,3 %, la mortalidad neonatal precoz se redujo el 73,4 %, la mortalidad neonatal tardía el 83,6 % y la posneonatal en 86,0 %. Las reducciones obtenidas en el período se distribuyeron uniformemente entre todas las provincias, aunque la mayor disminución se produjo en las provincias centrales y occidentales. Los rubros que más disminuyeron sus tasas fueron: enteritis y otras enfermedades diarreicas, infecciones respiratorias agudas, afecciones perinatales en general y las meningitis, aunque todas las causas reducen la mortalidad en el período. La natalidad descendió el 51,3 %, la fecundidad lo hizo en 30 %, el crecimiento demográfico bruto de la población disminuyó el 59,8 %, el parto institucional aumentó en 65,9 %, el bajo peso al nacer descendió el 36,9 %, la mortalidad perinatal se redujo el 67,2 %, los nacidos vivos disminuyeron el 21,1 % y la supervivencia infantil a los 5 años aumentó el 3,8 %. Esto ha sido posible debido principalmente a la decisión política de priorizar el sector de la salud y muy especialmente la salud maternoinfantil adoptada por nuestro Estado a principios de la década de los 60, lo que permitió alcanzar avances en la organización, calidad de la atención y una amplia cobertura de los servicios de salud. También fueron elementos importantes, el mejoramiento del nivel de vida y de la educación alcanzados por la población, las mejoras logradas en la situación sanitaria y epidemiológica, la distribución equitativa de los alimentos que prioriza a la madre y al niño. Un elemento fundamental en la última década ha sido el desarrollo del "médico de la familia" en la atención primaria y el mejoramiento de la atención hospitalaria. Por otra parte han contribuido de manera notable el establecimiento del Programa Nacional de Atención Maternoinfantil, que abarca las inmunizaciones, el control de las

  17. Radioresistant cell strain of human fibrosarcoma cells obtained after long-term exposure to X-rays

    1998-01-01

    A radioresistant cell strain from human fibrosarcoma HT1080 has been obtained after prolonged exposure to x-rays for 7 months (2 Gy per day, 5 days per week). This new strain, HT1080R, differs from HT1080 in a significantly increased ability of clonogenical survival, with coefficient α decreasing from 0.161 to 0.123 Gy -1 and coefficient β decreasing from 0.0950 to 0.0565 Gy -2 . Furthermore, the radioresistance of HT1080R proved to be stable in long-term passaged cultures as well as in frozen samples. Differences between the two cell lines are also observed in the G-banded karyotype; the new cell line shows monosomy of chromosome 17 and loss of 5p + and 11q + present in the parental cells. These data suggest that the radioresistance may have been caused by radiation-induced cell mutation and that the resistant cells may have been selected by repeated irradiations. In order to characterize this new strain, the ability of the cells to rejoin DNA double-strand breaks, the cell cycle distribution and the amount of apoptosis after irradiation have been estimated; however, no differences are observed between these two cell strains. Although the mechanism of the elevated radioresistance remains unknown, this pair of cell strains can provide a new model system for further investigations with regard to the mechanisms of cellular radioresistance. The results also show that any type of irradiation similar to the schedules used in radiotherapy can lead to the formation and selection of more radioresistant cell clones in vitro, a phenomenon with possible implications for radiotherapy.

    Even though bystander effects pertaining to radiation risk assessment has been extensively studied, the molecular players of radiation induced bystander effect (RIBE) in the context of cancer radiotherapy are poorly known. In this regard, the present study is aimed to investigate the effect of irradiated tumor cells on the bystander counterparts in mouse fibrosarcoma (WEHI 164 cells) tumor model. Mice co-implanted with WEHI 164 cells γ-irradiated with a lethal dose of 15 Gy and unirradiated (bystander) WEHI 164 cells showed inhibited tumor growth, which was measured in terms of tumor volume and Luc+WEHI 164 cells based bioluminescence in vivo imaging. Histopathological analysis and other assays revealed decreased mitotic index, increased apoptosis and senescence in these tumor tissues. In addition, poor angiogenesis was observed in these tumor tissues, which was further confirmed by fluorescence imaging of tumor vascularisation and CD31 expression by immuno-histochemistry. Interestingly, the growth inhibitory bystander effect was exerted more prominently by soluble factors obtained from the irradiated tumor cells than the cellular fraction. Cytokine profiling of the supernatants obtained from the irradiated tumor cells showed increased levels of VEGF, Rantes, PDGF, GMCSF and IL-2 and decreased levels of IL-6 and SCF. Comparative proteomic analysis of the supernatants from the irradiated tumor cells showed differential expression of total 24 protein spots (21 up- and 3 down-regulated) when compared with the supernatant from the unirradiated control cells. The proteins which showed substantially higher level in the supernatant from the irradiated cells included diphosphate kinase B, heat shock cognate, annexin A1, angiopoietin-2, actin (cytoplasmic 1/2) and stress induced phosphoprotein 1. However, the levels of proteins like annexin A2, protein S100 A4 and cofilin was found to be lower in this supernatant. In conclusion, our results provided deeper insight about

    Punica granatum L. var. granatum (Pomegranate), an herbaceous plant found in Iran, The aim of this study was to investigate the cytotoxic effects, induction of apoptosis, and the mechanism of cell death of ethanol extract from Punica granatum L. var. spinosa on the mouse fibrosarcoma cell line, WEHI-164. Various parts of the herbs were extracted from fruit using ethanol as the solvent, and the cytotoxicity and cell viability of the ethanolic extract were determined by the MTT assay. To determine whether necrosis or apoptosis is the predominant cause of cell death, cell death detection was performed using the ELISA method. The induction of apoptosis was confirmed using the terminal deoxynucleotidyl transferase- (TdT-) mediated dUTP nick end labeling (TUNEL) assay. Moreover, a sensitive immunoblotting technique was used to examine the production of Caspase-3 and Bcl2 proteins. Our findings suggested that the ethalonic extract of Punica granatum L. var. spinosa altered cell morphology, decreased cell viability, suppressed cell proliferation and induced cell death in a time- and dose-dependent manner in WEHI-164 cells (IC50 = 229.024μg/ml), when compared to a chemotherapeutic anticancer drug, Toxol (Vesper Pharmaceuticals), with increased nucleosome production from apoptotic cells. Induction of apoptosis by the plant extract was proved by the decrease of pro-Caspase-3 and Bcl2 proteins and quantitatively confirmed by Immunoblotting analysis. The results obtained from the present study have demonstrated the growth-inhibitory effect of Ethanol Extracts from Punica granatum L. var. spinosa, and clearly showed that apoptosis was the major mechanism of in-vitro cell death induced by the extract.

    Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between November 1992 and July 1999, 43 patients who had the disease detected in their fetal or infantile period were submitted to this study. Standardized diuretic renograms were obtained with 99m Tc-labeled diethylene-triaminepenta-acetate (Tc-99m-DTPA) or 99m Tc-labeled mercaptoacetyl triglycine (Tc-99m-MAG3) as radiopharmaceuticals. Drainage half-time clearance (T 1/2) of the activity at each region of interest set to encompass the entire kidney and the dilated pelvis was used as an index of quantitative analysis of UPJ obstruction. Initial T 1/2s of 32 kidneys with suspected UPJ obstruction were significantly longer than those of 37 without obstruction. T 1/2s of kidneys which had undergone pyeloplasty decreased promptly after surgery whereas those of units followed up without surgery decreased more sluggishly. These findings demonstrate that a standardized diuretic renographic analysis with T 1/2 can reliably assess infantile hydronephrosis with UPJ obstruction and be helpful in making a decision on surgical intervention.

Se revisó la información científica, relacionando el timerosal y las evidencias que permitan evaluar una posible asociación causal, con estudios epidemiológicos, ecológicos, biomoleculares y toxicológicos, de bioseguridad, toxicológicos fetales y sobre salud reproductiva. Se encontró múltiples asociaciones entre la exposición a timerosal y las enfermedades del neurodesarrollo infantil. Tal neurotoxicidad ocurre en los infantes y fetos de gestantes vacunadas por dosis acumulativa de mercurio. Las diversas evidencias implican al timerosal como el agente causante, agravante o disparador de las enfermedades del neurodesarrollo infantil. La toxicidad del mercurio obligó al retiro progresivo del timerosal de los medicamentos. Lamentablemente, en las vacunas, ha habido una sustancial demora en la demostración de su impacto negativo. Actualmente, existen vacunas sin timerosal, cuyo uso está ocasionando la disminución de la incidencia de las enfermedades del neurodesarrollo infantil.

    99m Tc-dimercaptosuccinic acid renal uptake (DMSA uptake) was measured in patients with hydronephrosis and we obtained the following conclusions. 1. Grades of hydronephrosis on IVP according to Oka's classification were compared with DMSA uptake. In 73 adult patients, the grade of hydronephrosis paralleled DMSA uptake well, but in 20 children it did not. 2. The changes of DMSA uptake pre- and post-nephrostomy were measured in 21 kidneys in 19 cases with congenital hydronephrosis. DMSA uptake of 7 infantile kidneys significantly increased post-nephrostomy, but in the cases over 1 year old significantly decreased after nephrostomy. DMSA uptake of the contralateral kidney significantly increased after nephrostomy in infants, but it did not change in the group over 1 year old. 3. In 15 kidneys of 13 cases with nephrostomy, DMSA uptake during closure and after opening of the nephrostomy catheter and DMSA uptake due to the radioisotope (RI) accumulated in the renal collecting system were measured. In the group over 1 year old, DMSA uptake decreased after opening nephrostomy nearly all and the extent of the decrease almost agreed with DMSA uptake due to RI accumulated in the renal collecting system. But in infants, DMSA uptake increased after opening nephrostomy in most cases and the extent of the change in DMSA uptake did not agree with DMSA uptake due to RI accumulated in the renal collecting system.

    Four cases of traumatic renal artery occlusion were described and illustrated. In two cases, direct blows to the abdomen compressed the renal artery against the vertebral column. Clinically, they were severely injured with macroscopic hematuria. Aortograms showed abrupt truncation of renal arteries. In the other two, rapid deceleration caused sudden displacement of the kidney producing an intimal tear with resultant thrombosis. Although they showed little injury without macrohematuria, aortograms revealed tapered occlusion of renal arteries. One of them developed hypertension. ''Rim sign'' of post-contrast CT and hypertension resulted from traumatic renal artery occlusion were reviewed. (author)

    Vanishing white matter disease (VWM) is one of the most prevalent inherited leukoencephalopathies in childhood. Infantile VWM is more severe but less understood than the classic early childhood type. We performed a follow-up study on 14 infantile and 26 childhood patients to delineate the natural history and neuroimaging features of VWM. Infantile and childhood patients shared similarities in the incidence of epileptic seizure (35.7 vs. 38.5%) and episodic aggravation (92.9 vs. 84.6%). Developmental delay before disease onset was more common in infantile patients. Motor disability was earlier and more severe in infantile VWM. In survivors with disease durations of 1-3 years, the Gross Motor Function Classification System (GMFCS) was classified as IV-V in 66.7% of infantile and only 29.4% of childhood patients. Kaplan-Meier survival curve analysis indicated that the 5-year survival rates were 21.6 and 91.3% in infantile and childhood VWM, respectively. In terms of MRI, infantile patients showed more extensive involvement and earlier rarefaction, with more common involvement of subcortical white matter, internal capsule, brain stem and dentate nuclei of the cerebellum.

    Increasing evidence suggests a possible relationship between mesenchymal stem cells (MSCs) and sarcoma. MSCs are hypothesized to be the cells initiating sarcomagenesis, and cancer stem cells (CSCs) sharing features of MSCs have been identified in sarcomas. Here, we report on the characteristics of a bone marrow-derived rat mesenchymal stem cell line that spontaneously transformed in long-term culture. The rat transformed mesenchymal stem cells (rTMSCs) produced soft-tissue fibrosarcomas in immunocompromised mice and immunocompetent rats. In vitro, the rTMSCs displayed increased proliferation capacity compared to the untransformed cell line. The transformed MSCs maintained the mesenchymal phenotype by expression of the stem cell marker CD 90 and the lack of hematopoietic and endothelial markers. Cytogenetic analysis detected trisomy 6 in the rTMSCs. Side population (SP) isolation and tumorsphere cultivation of the transformed cells confirmed the presence of CSCs among the rTMSCs. Importantly, the rTMSCs retained their differentiation capacity towards osteogenic and adipogenic lineages. This transformed MSC-based cell line may be valuable in examining the balance in a mixed cell population between cancer stem cell properties and the ability to differentiate to specific non-transformed cell populations. Moreover, it may also be a useful tool to evaluate the efficacy of novel targeted immunotherapies in vivo. - Highlights: • Spontaneously transformed rat MSCs (rTMSCs) share characteristics with normal MSCs. • rTMSCs possess a side population, enriched with tumorigenic cells. • rTMSCs model fibrosarcoma in vivo.

    We have used very low-frequency electron paramagnetic resonance (EPR) oximetry to measure the change in oxygen concentration (delta pO2) due to change in breathing atmosphere in FSa and NFSa fibrosarcomas implanted in the legs of C3H mice infused with perfluoro-octylbromine (PFOB). Measurements in each tumor were made before and after the administration of the high-density (47% v/v) perfluorocarbon PFOB, perflubron (Alliance Pharmaceutical Corporation, San Diego, CA). Measurements in each tumor were also made, after the administration of the PFOB, both before (PFOB/air) and after the administration of carbogen (95% O2 + 5% CO2, PFOB/carbogen). Large changes (delta p02) relative to PFOB/air oxygenation were seen with the administration of PFOB/carbogen. No significant difference in oxygen concentration was seen between air-breathing mice with and without PFOB. The mean delta pO2 for FSa tumors was 13 +/- 6 torr, while the mean for NFSa fibrosarcomas was 28 +/- 7 torr. There were such large intertumor differences that the trend toward a smaller change in the more hypoxic FSa tumors was not significant (P = 0.13). This paper describes a novel method of measuring differences in oxygenation in tumor tissues. The results of such measurements indicate large differences in pO2 response to different breathing atmospheres in PFOB-infused tumors of similar histology. The intertumor delta pO2 differences may correlate with differences in radiation response.

    The immunophenotypization, tumorigenicity and immunogenicity of the tumor were characterized. The tumorigenic dose of the fibrosarcoma G5:1:13 for mice C3H/DiSn when administered s.c. is 1x10 5 per mouse. With this dose, tumors with an average volume of 64 mm 3 on day 6 developed; 98-100% mice died on day 120. The phenotype of the fibrosarcoma, which is immunogenic, is MHC-I + , HNC-II - , B7 - , B7.2 - . After administration of irradiated tumor cells (2 doses, s.c., 1x10 6 per mouse), a tumor developed in none of the animals to which the non-irradiated tumor cells had been administered. The effect of the individual factors was examined. Gamma radiation affected survival of the mice as follows: 2x8 Gy (60%), 4x6 Gy (80%), 5x5 Gy (80%), 3x7 Gy (80%), in positive correlation with the tumor size. The growth was affected similarly by MTP-PE (40%), diclofenac (40%), ibuprofen (40%) and flurbiprofen (30%). When diclofenac was combined with MTP-PE, a surprising strengthening of the tumor growth was observed. This finding is very important in view of the clinical use of MTP-PE and inhibitors of arachidonic acid metabolism in the treatment of tumorous diseases

    A gingko biloba extract (GBE) has been known as a hypoxic cell radiosensitizer. Its mechanisms of action are increase of the red blood cell deformability, decrease the blood viscosity, and decrease the hypoxic cell fraction in the tumor. The aims of this study were to estimate the effect of GBE on fractionated radiotherapy and to clarify the mechanism of action of the GBE by estimating the blood flow in tumor and normal muscle. Fibrosarcoma (FSall) growing in a C3H mouse leg muscle was used as the tumor model. When the tumor size reached 7 mm in diameter, the GBE was given intraperitoneally at 1 and 25 hours prior to irradiation. The tumor growth delay was measured according to the various doses of radiation (3, 6, 9, 12, Gy and 15 Gy) and to the fractionation (single and fractionated irradiation) with and without the GBE injection. The radiation dose to the tumor the response relationships and the enhancement ratio of the GBE were measured. In addition, the blood flow of a normal muscle and a tumor was compared by laser Doppler flowmetry according to the GBE treatment. When the GBE was used with single fraction irradiation with doses ranging from 3 to 12 Gy, GBE increased the tumor growth delay significantly (ρ < 0.05) and the enhancement ratio of the GBE was 1.16. In fractionated irradiation with 3 Gy per day, the relationships between the radiation dose (D) and the tumor growth delay (TGD) were TGD (days) = 0.26 x D (Gy)+0.13 in the radiation alone group, and the TGD (days) = 0.30 x D (Gy) + 0.13 in the radiation with GBE group. As a result, the enhancement ratio was 1.19 (95% confidence interval; 1.13 ∼ 1.27). Laser Doppler flowmetry was used to measure the blood flow. The mean blood flow was higher in the muscle (7.78 mL/100 g/min in tumor and the 10.15 mL/100 g/min in muscle, ρ = 0.0001) and the low blood flow fraction (less than 2 mL/100 g/min) was higher in the tumor (0.5% vs. 5.2%, ρ = 0.005). The blood flow was not changed with the GBE in normal

    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

    We describe a recently noted association of congenital (infantile) pseudarthrosis of the lower leg with osteofibrous dysplasia. The patient was a 2-year-old boy who presented with a deformed left ankle joint and three cutaneous cafe-au-lait spots. Radiography demonstrated pseudarthrosis of the left distal fibula and a round lucent lesion adjacent to the proximal part of the pseudarthrosis. Histologically, the surgically removed fibula with pseudarthrosis showed a fibromatosis-like fibrovascular proliferation and nonspecific reparative changes. The focal lucent area demonstrated a fibro-osseous lesion, which was histologically identical to osteofibrous dysplasia. This case provides further evidence that osteofibrous dysplasia may be associated with congenital (infantile) pseudarthrosis of the lower leg. (orig.)

    2011-01-01

    Objective: Infantile colic is a common problem among infants age 3 days to 3 months. It may affect parental feelings negatively and the parents may undertake all kinds of actions to stop excessive crying. The objective of this study was to assess the incidence of infantile colic and its risk factors in infants born in District Mansehra. Methods: In this prospective study, all those newborn babies were included who were born at King Abdullah Teaching Hospital Mansehra between January 1 2008 and March 31, 2008, and those newborn babies who were brought to children OPD for routine check-up and EPI centre for vaccination of this hospital during this time period. For every infant, gender, mode of delivery, gestational age at birth, birth weight, birth order, and mother's reproductive history were collected. These babies were seen at least once in a week up to 12 weeks and history from the mothers about the duration of crying and fussiness behaviour was recorded. At the end of 3 months the infants were again assessed and additional information on infant nutritional source was obtained and any medication used for colic relief was identified. Cases of colic were identified by applying Wessel criteria to recorded data. Chi-square tests were used. Results: From total 512 infants, follow-up was completed for 426 infants. In total, 90 infants (21.77%) satisfied the Wessel criteria for infantile colic. No statistical significance was found between colicky and non-colicky infants according to sex, gestational age at birth, birth weight, type of delivery, and, infant's feeding pattern. However, firstborn infants had higher rate for developing colic (p=0.03). Conclusion: Prevalence of colic was 21.77% in this infant population of District Mansehra. Except for birth order, no other variable was significantly associated with infantile colic. (author)

    Renal artery disease is a potentially correctable cause of hypertension. Previous studies have suggested the utility of duplex sonography in accurately detecting and grading the severity of renal artery stenosis. The purpose of this paper is to evaluate color flow Doppler for this use. Forty-three kidneys were examined by color-flow Doppler and conventional duplex sampling in patients with suspected renovascular hypertension or those undergoing aortography for unrelated reasons. Doppler tracings were obtained from the renal arteries and aorta with calculation of the renal aortic ratio (RAR) and resistive index (RI). Results of Doppler sampling with color flow guidance were compared with aortograms in a blinded fashion

    Full Text Available Primary renal cell carcinomas have rarely been reported in patients with crossed fused renal ectopia. We presented a patient with right to left crossed fused kidney harbouring renal tumor. The most frequent tumor encountered in crossed fused renal ectopia is renal cell carcinoma. In this case, partial nephrectomy was performed which pave way to preservation of the uninvolved both renal units. Due to unpredictable anatomy, careful preoperative planning and meticulous delineation of renal vasculature is essential for preservation of the uninvolved renal units.

    Full Text Available Este artigo é resultado de um estudo realizado em uma creche pública pertencente à rede municipal de educação de Sinop - MT. Objetivamos compreender o movimento corporal das crianças como parte do desenvolvimento integral das crianças. E também entender como os profissionais trabalham a especificidade do corpo infantil, dos movimentos das crianças durante a rotina da instituição de uma turma de crianças de dois a três anos de idade. Optamos em focalizar a pesquisa na área da Educação Infantil por entender que as crianças desta faixa etária apresentam características importantes no desenvolvimento corporal, visto que muitas vezes na educação infantil o movimento é considerado como ‘indisciplina’, fazendo com que a criança, na maioria das vezes permanece quietas e sentadas em suas cadeiras. Diante de tal propósito, buscamos uma metodologia que nos possibilitasse apreender o movimento corporal da criança e encontramos na pesquisa qualitativa, através da ‘observação participante’, trilhas que nos conduziram à construção de conhecimentos. Como pesquisadora, permanecemos na instituição investigada por quase três meses, em horários intercalados, utilizando o caderno de campo, no qual registramos as observações realizadas, bem como as entrevistas com as professoras da referida turma. Os principais referenciais utilizados para o estudo foram: Vygotsky, Piaget, Vitor Fonseca e Henri Wallon. De acordo com o observado em campo e leituras teóricas, ressaltamos com este estudo a importância do movimento para as crianças e sua contribuição no desenvolvimento infantil pleno.Palavras-chave: educação; educação infantil; maternal II; movimento; sociointeracionismo.

  13. Dimerization of endogenous MT1-MMP is a regulatory step in the activation of the 72-kDa gelatinase MMP-2 on fibroblasts and fibrosarcoma cells

    The secreted gelatinase matrix metalloprotease-2 (MMP-2) and the membrane-anchored matrix metalloprotease MT1-MMP (MMP-14), are central players in pericellular proteolysis in extracellular matrix degradation. In addition to possessing a direct collagenolytic and gelatinolytic activity......, these enzymes take part in a cascade pathway in which MT1-MMP activates the MMP-2 proenzyme. This reaction occurs in an interplay with the matrix metalloprotease inhibitor, TIMP-2, and the proposed mechanism involves two molecules of MT1-MMP in complex with one TIMP-2 molecule. We provide positive evidence...... that proMMP-2 activation is governed by dimerization of MT1-MMP on the surface of fibroblasts and fibrosarcoma cells. Even in the absence of transfection and overexpression, dimerization of MT1-MMP markedly stimulated the formation of active MMP-2 products. The effect demonstrated here was brought about...

    Matrix metalloproteinase (MMP)-9 degrades type IV collagen in the basement membrane and plays crucial roles in several pathological implications, including tumorigenesis and inflammation. In this study, we analyzed the effect of flavonols on MMP-9 expression in phorbol-12-myristate-13-acetate (PMA)-induced human fibrosarcoma HT-1080 cells. Galangin and kaempferol efficiently decreased MMP-9 secretion, whereas fisetin only weakly decreased its secretion. Galangin and kaempferol did not affect cell viability at concentrations up to 30 μM. Luciferase reporter assays showed that galangin and kaempferol decrease transcription of MMP-9 mRNA. Moreover, galangin and kaempferol strongly reduce IκBα phosphorylation and significantly decrease JNK phosphorylation. These results indicate that galangin and kaempferol suppress PMA-induced MMP-9 expression by blocking activation of NF-κB and AP-1. Therefore, these flavonols could be used as chemopreventive agents to lower the risk of diseases involving MMP-9.

    Arginine-arginine-leucine (RRL) is considered a tumor endothelial cell-specific binding sequence. RRL-containing peptide targeting tumor vessels is an excellent candidate for tumor imaging. In this study, we developed RRL-containing hexapeptides and evaluated their feasibility as a tumor imaging agent in a HT-1080 fibrosarcoma-bearing murine model. The hexapeptide, glutamic acid-cysteine-glycine (ECG)-RRL was synthesized using Fmoc solid-phase peptide synthesis. Radiolabeling efficiency was evaluated using instant thin-layer chromatography. Uptake of Tc-99m ECG-RRL within HT-1080 cells was evaluated in vitro by confocal microscopy and cellular binding affinity was calculated. Gamma images were acquired In HT-1080 fibrosarcoma tumor-bearing mice, and the tumor-to-muscle uptake ratio was calculated. The inflammatory-to-normal muscle uptake ratio was also calculated in an inflammation mouse model. A biodistribution study was performed to calculate %ID/g. A high yield of Tc-99m ECG-RRL complexes was prepared after Tc-99m radiolabeling. Binding of Tc-99m ECG-RRL to tumor cells had was confirmed by in vitro studies. Gamma camera imaging in the murine model showed that Tc-99m ECG-RRL accumulated substantially in the subcutaneously engrafted tumor and that tumoral uptake was blocked by co-injecting excess RRL. Moreover, Tc-99m ECG-RRL accumulated minimally in inflammatory lesions. We successfully developed Tc-99m ECG-RRL as a new tumor imaging candidate. Specific tumoral uptake of Tc-99m ECG-RRL was evaluated both in vitro and in vivo, and it was determined to be a good tumor imaging candidate. Additionally, Tc-99m ECG-RRL effectively distinguished between cancerous tissue and inflammatory lesions.

    Background: Hypoxia inducible factor-1 has been identified as a potential target to overcome hypoxia-induced radioresistance The aim of the present study was to investigate whether selective HIF-1 inhibition via small interfering RNA (siRNA) targeting hypoxia-inducible factor 1{alpha} (HIF-1{alpha}) affects hypoxia-induced radioresistance in HT 1080 human fibrosarcoma cells. Material and Methods: HIF-1{alpha} expression in HT 1080 human fibrosarcoma cells in vitro was silenced using HIF-1{alpha} siRNA sequence primers. Quantitative real-time polymerase chain reaction assay was performed to quantify the mRNA expression of HIF-1{alpha}. HIF-1{alpha} protein levels were studied by Western blotting at 20% (air) or after 12 hours at 0.1% O{sub 2} (hypoxia). Cells were assayed for clonogenic survival after irradiation with 2, 5, or 10 Gy, under normoxic or hypoxic conditions in the presence of HIF-1{alpha}-targeted or control siRNA sequences. A modified oxygen enhancement ratio (OER') was calculated as the ratio of the doses to achieve the same survival at 0.1% O{sub 2} as at ambient oxygen tensions. OER' was obtained at cell survival levels of 50%, 37%, and 10%. Results: HIF-1{alpha}-targeted siRNA enhanced radiation treatment efficacy under severely hypoxic conditions compared to tumor cells treated with scrambled control siRNA. OER was reduced on all survival levels after treatment with HIF-1{alpha}-targeted siRNA, suggesting that inhibition of HIF-1 activation by using HIF-1{alpha}-targeted siRNA increases radiosensitivity of hypoxic tumor cells in vitro. Conclusion: Inhibition of HIF-1 activation by using HIF-1{alpha}-targeted siRNA clearly acts synergistically with radiotherapy and increase radiosensitivity of hypoxic cells in vitro. (orig.)

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

    Objective: To study the value of diuretic renography (DR) in evaluation of renal function after operation in congenital obstructive hydronephrosis (HN) in neonates and infants. Methods: Thirty-two patients with the disease detected in their neonatal or infantile period were submitted to this study. DR was performed 1 to 4 times on all patients during follow-up. The qualitative evaluation of renal function after operation was combined with renal morphology, renogram curve and several other renal function indexes. The major index of quantitative evaluation of renal function is the change of renal blood perfusion rate (BPR). Results: The results of qualitative evaluation with 67 DR in the affected kidney (AK): 6 totally recovered, 35 significantly improved, 7 improved, 9 unchanged, 10 deteriorated. The changes of BPR of the groups with qualitative evaluation differed from each other significantly (F=7.77, P 0.05 and r=0.166, P>0.05, respectively). Conclusion: The change of BPR is a good index of renal function after operation, but only the quantitative evaluation being combined with qualitative evaluation can be considered a complete evaluation

  8. Renal imaging in paediatrics

    The most frequent renal diseases in paediatrics include urinary tract infections, hydronephrosis, kidney anomalies and reflux. The main reason for performing DMSA scintigraphy in paediatrics is the detection of cortical abnormalities related to urinary tract infection. Because the amount of tracer retained in the tubular cells is associated with the distribution of functioning renal parenchyma in the kidney, it is possible, to evaluate the split renal function. In comparison to ultrasound and intravenous urography the sensitivity in the detection of acute as well as chronic inflammatory changes is very high, however less specific. An indication for a renography in neonates and children is beside an estimation of the total renal function and the calculation of the split renal function, the assessment of renal drainage in patients with unclear dilatation of the collecting system in ultrasound. The analysis of the time activity curve provides, especially for follow-up studies, a reproducible method to assess the urinary outflow. The diuretic scintigraphy allows the detection of urinary obstruction. Subsequently it is possible to image the micturition phase to detect vesico-ureteric reflux (indirect MCU) after drainage of tracer from the renal pelvis. An reflux in the ureters or the pelvicalyceal system is visible on the scintigraphic images and can be confirmed by time activity curves. A more invasive technique is the direct isotope cystography with bladder catheterization. The present paper should give an overview about the role of nuclear medicine in paediatric urology. (orig.)

  9. Perioperative acute renal failure.

    LENUS (Irish Health Repository)

    2012-02-03

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

  10. Cadmium and renal cancer

    International Nuclear Information System (INIS)

    Il'yasova, Dora; Schwartz, Gary G.

    2005-01-01

    Background: Rates of renal cancer have increased steadily during the past two decades, and these increases are not explicable solely by advances in imaging modalities. Cadmium, a widespread environmental pollutant, is a carcinogen that accumulates in the kidney cortex and is a cause of end-stage renal disease. Several observations suggest that cadmium may be a cause of renal cancer. Methods: We performed a systematic review of the literature on cadmium and renal cancer using MEDLINE for the years 1966-2003. We reviewed seven epidemiological and eleven clinical studies. Results: Despite different methodologies, three large epidemiologic studies indicate that occupational exposure to cadmium is associated with increased risk renal cancer, with odds ratios varying from 1.2 to 5.0. Six of seven studies that compared the cadmium content of kidneys from patients with kidney cancer to that of patients without kidney cancer found lower concentrations of cadmium in renal cancer tissues. Conclusions: Exposure to cadmium appears to be associated with renal cancer, although this conclusion is tempered by the inability of studies to assess cumulative cadmium exposure from all sources including smoking and diet. The paradoxical findings of lower cadmium content in kidney tissues from patients with renal cancer may be caused by dilution of cadmium in rapidly dividing cells. This and other methodological problems limit the interpretation of studies of cadmium in clinical samples. Whether cadmium is a cause of renal cancer may be answered more definitively by future studies that employ biomarkers of cadmium exposure, such as cadmium levels in blood and urine

    Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited. We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months). A preplanned interim analysis was conducted to identify the regimen to study for the final efficacy analysis. The primary end point was success (complete or nearly complete resolution of the target hemangioma) or failure of trial treatment at week 24, as assessed by independent, centralized, blinded evaluations of standardized photographs. Of 460 infants who underwent randomization, 456 received treatment. On the basis of an interim analysis of the first 188 patients who completed 24 weeks of trial treatment, the regimen of 3 mg of propranolol per kilogram per day for 6 months was selected for the final efficacy analysis. The frequency of successful treatment was higher with this regimen than with placebo (60% vs. 4%, P<0.001). A total of 88% of patients who received the selected propranolol regimen showed improvement by week 5, versus 5% of patients who received placebo. A total of 10% of patients in whom treatment with propranolol was successful required systemic retreatment during follow-up. Known adverse events associated with propranolol (hypoglycemia, hypotension, bradycardia, and bronchospasm) occurred infrequently, with no significant difference in frequency between the placebo group and the groups receiving propranolol. This trial showed that propranolol was effective at a dose of 3 mg per kilogram per day for 6 months in the treatment of infantile hemangioma. (Funded by

    Renovascular hypertension is a common cause of pediatric hypertension. In the fraction of cases that are unrelated to syndromes such as neurofibromatosis, patients with a solitary stenosis on a branch of the renal artery are common and can be diagnostically challenging. Imaging techniques...... that perform well in the diagnosis of main renal artery stenosis may fall short when it comes to branch artery stenosis. We report 2 cases that illustrate these difficulties and show that a branch artery stenosis may be overlooked even by the gold standard method, renal angiography....

    2015-02-01

    Atherosclerotic renal artery stenosis (RAS) is the single largest cause of secondary hypertension; it is associated with progressive renal insufficiency and causes cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy, including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid-lowering agents, and antiplatelet therapy, is advised in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe RAS are likely to benefit from renal artery revascularization. Screening for RAS can be done with Doppler ultrasonography, CT angiography, and magnetic resonance angiography. Copyright © 2015 Elsevier Inc. All rights reserved.

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    2016-07-01

    We present a case series of a rare tumor, the desmoplastic infantile ganglioglioma (DIG) with MRI diffusion and perfusion imaging quantification as well as histopathologic characterization. Four cases with pathologically-proven DIG had diffusion weighted imaging (DWI) and two of the four had dynamic susceptibility contrast imaging. All four tumors demonstrate DWI findings compatible with low-grade pediatric tumors. For the two cases with perfusion imaging, a higher relative cerebral blood volume was associated with higher proliferation index on histopathology for one of the cases. Our results are discussed in conjunction with a literature review.

    While infantile myofibromatosis is the most common mesenchymal tumour of infancy, only around 300 cases have been reported. The authors report a 33-year-old para 1 with an uncomplicated, dichorionic diamniotic twin pregnancy who was diagnosed with an intrauterine death of one twin at 36+5 weeks gestation. At caesarean section, a macerated male stillborn weighing 2.72 kg was delivered. Postmortem examination revealed a pedunculated lesion attached to the left shoulder and underlying muscle consistent with a congenital myofibroma. The cause of death was postulated to be haemorrhage from the tumour surface causing fetal anaemia. PMID:22674951

    2015-01-01

    Hydrocephalus is a common but complex condition caused by physical or functional obstruction of CSF flow that leads to progressive ventricular dilatation. Though hydrocephalus was recently estimated to affect 1.1 in 1,000 infants, there have been few systematic assessments of the causes of hydrocephalus in this age group, which makes it a challenging condition to approach as a scientist or as a clinician. Here, we review contemporary literature on the epidemiology, classification and pathogenesis of infantile hydrocephalus. We describe the major environmental and genetic causes of hydrocephalus, with the goal of providing a framework to assess infants with hydrocephalus and guide future research. PMID:24932902

La anamnesis remota es de poco valor, más relevantes para el diagnóstico constituyen el examen del paciente en el presente y las escalas de cuantificación del autismo (las cuales son de utilidad en el diagnóstico diferencial entre el trastorno autístico tipo Kanner y los trastornos autísticos atípicos. Las pruebas de inteligencia standard se deben aplicar según el nivel de funcionamiento del paciente y si no clasificara es más bien por el bajo cociente de inteligencia que por su comportamiento autístico. El clínico debería tener presente la posibilidad del diagnóstico de autismo cuando examina niños pequeños con problemas de desarrollo y utilizar escalas de síntomas autísticos adecuados a los primeros años de vida. Se recomienda el uso de la prueba de Bo Olsson en el diagnóstico diferencial de autismo de Kanner, síndrome de Rett y daño cerebral temprano en la etapa preescolar.The limits of the austistic syndrome as well as the evolution of the infantile autism concept since Kanner to the latest psychiatric classifications are reviewed. The results of our research on the positive diagnosis of infantile autism are reported. The patient's medical examination and the autism quantification scales (useful for the diferential diagnosis between the Kanner type autistic disorder and the atypical autistic disorders are more important for the diagnosis than the remote anamnesis, which is of little value. The standard intelligence test should be applied according to the patients functioning level and if he would not classify it would be because of his low intelligence quotient and not because of his autistic behaviour.

    Full Text Available Primary Renal Sarcoma is rare tumor comprising only 1% of all renal tumours. Synovial sarcomas are generally deep-seated tumors arising in the proximity of large joints of adolescents and young adults and account for 5-10% of all soft tissue tumours. Primary synovial sarcoma of kidney is rare and has poor prognosis. It can only be diagnosed by immunohistochemistry. It should be considered as a differential in sarcomatoid and spindle cell tumours. We present a case of 33-year-old female, who underwent left sided radical nephrectomy for renal tumour. Histopathology and genetic analysis diagnosed it to be primary renal synovial sarcoma.

    The frequent application of ultrasound and radiological imaging for non-urological indications in recent years has resulted in an increase in the diagnosis of small renal masses. The treatment options for patients with a small renal mass include active surveillance, surgery (both open and minimally invasive) as well as ablative techniques. As there is a risk for metastatic spread even in small renal masses surgical extirpation remains the treatment of choice in most patients. Ablative procedures, such as cryoablation and radiofrequency ablation are appropriate for old and multi-morbid patients who require active treatment of a small renal mass. Active surveillance is an alternative for high-risk patients. Meticulous patient selection by the urologist and patient preference will determine the choice of treatment option in the future.

    Patterson, J.E.; Andriole, V.T.

    1987-01-01

    Our knowledge of the spectrum of renal abscesses has increased as a result of more sensitive radiologic techniques. The classification of intrarenal abscess now includes acute focal bacterial nephritis and acute multifocal bacterial nephritis, as well as the previously recognized renal cortical abscess, renal corticomedullary abscess, and xanthogranulomatous pyelonephritis. In general, the clinical presentation of these entities does not differentiate them; various radiographic studies can distinguish them, however. The intrarenal abscess is usually treated successfully with antibiotic therapy alone. Antistaphylococcal therapy is indicated for the renal cortical abscess, whereas therapy directed against the common gram-negative uropathogens is indicated for most of the other entities. The perinephric abscess is often an elusive diagnosis, has a more serious prognosis, and is more difficult to treat. Drainage of the abscess and sometimes partial or complete nephrectomy are required for resolution. 73 references

    The initial goal in treatment for infantile cholestasis is to exclude surgical cholestasis, especially biliary atresia (BA). In this study, we retrospectively reviewed the diagnostic course of infantile cholestasis. Between 2000 and 2009, a total of 44 infants with cholestasis were referred to our department. The median age at admission was 54 days (range: 0-143 days). The medical charts of these infants were reviewed. The initial diagnostic approach was ultrasonography followed by the qualitative detection of bilirubin in stool. The 35 infants with acholic stool and/or a small or absent gallbladder on ultrasonography were subsequently examined by hepatobiliary scintigraphy (HBS). Twenty-nine infants with negative scintigraphy findings underwent intraoperative cholangiography (lOC), and BA was finally confirmed in 24 of 44. A choledochal cyst was noted in 2, Alagille syndrome in 2, cytomegalovirus infection in 2, panhypopituitarism in 2, multiple hemangiomas of the liver in 1, and cholecystolithiasis in 1. The remaining 10 infants were diagnosed as having neonatal hepatitis. The sensitivity and specificity of HBS for BA were 100% and 54.5%, respectively. HBS is a useful modality for detection of BA with a sensitivity of 100%. The indication for IOC should depend on these scan results. (author)

En ese sentido, se destaca que durante algún tiempo el quehacer de los infantes en el mercado de trabajo era considerado como un medio para que aprendieran determinado oficio, así como que dicha connotación no ha dejado de existir, pero ahora coexiste con otras tendencias asociadas a la delincuencia organizada, tales como prostitución, pornografía y turismo infantil; es decir, con actividades vinculadas estrechamente con la trata de personas. La pretensión es evidenciar el problema y las principales prácticas de quienes llevan a cabo dicho comportamiento; por lo que hubo necesidad de recurrir a la aplicación de una entrevista focalizada, basada en ocho informantes, con la finalidad de conocer la percepción de personas involucradas en dicha problemática. Al final del trabajo, lo observado es que la problemática en cuestión sigue creciendo en México; situación que es corroborada por los datos que aportan diversas instituciones, que señalan que en la actualidad este país ocupa el primer lugar en dicho comportamiento.

    2014-06-01

    Full Text Available El desarrollo de la marcha infantil es un proceso especialmente complejo en que el intervienen factores motores, perceptivos y cognitivos. Desde el nacimiento, el niño integra la información recibida y realiza un progresivo control cortical sobre los patrones neuromotores innatos para desarrollar diferentes formas de locomoción hasta la marcha independiente. Estas ideas no son novedosas pero se están revisando en la actualidad y han motivado numerosos cambios en el estudio del desarrollo infantil. La consideración de la adquisición de la marcha como un aprendizaje en situaciones de constante cambio permite comprender la marcha como acción, cuya realización implica la adquisición de nuevas capacidades de interacción y conocimientos. En este trabajo se exponen los principales conocimientos acerca de este proceso de aprendizaje y se propone destacar las alteraciones de la marcha como indicadores de dificultades en el desarrollo, que requieren una valoración y un abordaje terapéutico interdisciplinares.

    Full Text Available El estudio identifica y analiza las interacciones vinculares existentes en el sistema de cuidado infantil de niños con y sin desnutrición crónica en un mismo contexto de pobreza. Este es un estudio multimétodo, basado en información de campo recopilada y en una construcción teórica que emergió a partir de los resultados obtenidos, ampliando el marco conceptual de la desnutrición infantil. La constelación y gestión del cuidado son dos categorías emergentes, que contribuyen a comprender que en los diferentes escenarios donde transitan los niños hay diversos cuidadores que varían en calidad, permanencia y coherencia repercutiendo esta situación en su estado nutricional. Si bien las mujeres se constituyen en las gestoras principales del cuidado, no son ellas las únicas responsables del cuidado y por ello se recomienda fortalecer las redes de apoyo familiar y comunitario.

    Full Text Available Cases of benign infantile convulsions with mild gastroenteritis (BICE treated in our hospital from 2008 to 2012 were analyzed retrospectively. Among the 65 cases of convulsions with acute diarrhea, there were 18 cases of BICE, 15 cases of febrile seizures, 13 cases of epilepsy, 6 cases of viral encephalitis, 6 cases of hyponatremia encephalopathy, 3 cases of hypernatremia encephalopathy, 2 cases of toxic encephalopathy, and 2 cases of hypocalcemia convulsion. The convulsion occurred mostly during the first 2 d of the illness and was in a generalized tonic or tonic-clonic form. Positive rotavirus antigens in the BICE patients were detected in 83.33% (15/18. Phenobarbital was administered after the first convulsion (5-10 mg/kg, and diazepam was given intravenously in case of recurrence (0.10-0.30 mg/kg. BICE occurs frequently in infantile and controlling relapse is the main purpose. The prognosis is good. doi: 10.3969/j.issn.1672-6731.2014.03.019

Uma pesquisa de campo foi conduzida junto a seis díades de mães com suas respectivas filhas. Como estratégia de pesquisa, uma narrativa ficcional foi conduzida com as crianças; enquanto entrevistas foram usadas com as mães. Como resultado, observou-se que vários estímulos levam as crianças a consumirem serviços estéticos. Entre estes, a referência materna, as influências de familiares, amigos da escola e da mídia, através da televisão e internet. De forma secundária, foi registrado que os serviços mais desejados e consumidos pelo público infantil foram os de manicure e cabelereiro. Em termos de papeis, as mães adquirem o serviço, e dividem com suas filhas o papel de decisão, ao determinarem, juntas, como o consumo acontecerá.

  12. [An atypical presentation of Infantile Alexander disease lacking macrocephaly].

    Science.gov (United States)

    Esmer, Carmen; Villegas-Aguilera, Miguel; Morales-Ibarra, Juan José; Bravo-Oro, Antonio

    Alexander disease is a rare form of leukodystrophy that involves mainly astrocytes; it is inherited in an autosomal recessive manner and occurs by mutations in the GFAP gene, located on chromosome 17q21. It can occur at any age and its infantile form is characterized by macrocephaly, seizures, severe motor and cognitive delay, and progressive spasticity or ataxia. An 8-month-old female was evaluated with a history of neurodevelopmental delay and unprovoked focal motor seizures. Physical examination showed normal head circumference, increased motor responses to tactile and noise stimuli, pyramidal signs and no visceromegalies. Widespread hypodense white matter was found on magnetic resonance and lumbar puncture showed hyperproteinorrachia. Krabbe disease was ruled out by enzymatic assay and gene sequencing of GALC. In the reassessment of the case, abnormalities in neuroimaging lead to suspicion of Alexander disease, and GFAP gene sequencing reported a pathogenic mutation in exon 4 c.716G>A, which caused a change of arginine to histidine at position 239 of the protein (p.Arg239His). The radiographic signs observed in the resonance were decisive for the diagnosis, later confirmed by molecular study. It is important to consider that certain mutations are not associated with macrocephaly, which may cause delay in diagnosis. Copyright © 2016 Hospital Infantil de México Federico Gómez.

    Aim: This study aims to analyze computed tomography (CT) and magnetic resonance (MR) imaging features of infantile hepatic hemangioendotheliomas before and after treatment. Materials and methods: CT and MR examinations of seven infants with biopsy proven hepatic hemangioendotheliomas were retrospectively analyzed. The distribution, number, size, imaging appearance, enhancement pattern and post-treatment changes of the tumors were evaluated. Results: A total of 153 hepatic hemangioendotheliomas were detected on CT (111) and MR (42) imaging. In six infants, 109/111 (98.2%) tumors were hypodense and 2/111 (1.8%) lesions contained calcification on unenhanced CT. On MR imaging, all 42 lesions in one infant were heterogeneously T1-hypointense and T2-hyperintense compared to the normal liver parenchyma. Contrast-enhanced CT and MRI showed peripheral rim (51.6%), uniform (48.4%), fibrillary (33.3%), and nodular (28.8%) contrast enhancement in the hepatic arterial phase. Homogeneous (100%), rim (98.2%) and mixed enhancement patterns were noted in tumors 2.0 cm and 1.0-2.0 cm in diameter respectively in the hepatic arterial phase. In three patients who underwent steroid therapy, follow-up CT examination demonstrated tumor size reduction and increased intra-tumoral calcification in two patients. Conclusion: Infantile hepatic hemangioendotheliomas show some typical imaging features and size-dependent pattern of contrast enhancement on CT and MR imaging, which allow accurate imaging diagnosis and post-treatment evaluation.

    2014-01-01

    We present a case of infantile holocord ependymoma in a 4-month-old boy who presented with infection of ventriculoperitoneal shunt done elsewhere for a communicating hydrocephalus. On magnetic resonance imaging, a diffuse holocord T2-hyperintense, T1-hypointense intramedullary bulky lesion with syringomyelia in the cervical level was seen. To the best of our knowledge, this is the first case of infantile holocord ependymoma. As the extent of morbidity associated with a spinal cord tumor is high, an increased level of suspicion and the need for a complete spinal cord screening in a case of infantile hydrocephalus without obvious clinical and radiological evidence of intracranial abnormality is emphasized.

    Full text: Renal artery stenosis (RAS) is a common condition that may lead to hypertension, progressive renal dysfunction and cardiovascular morbidity. Catheter-based therapy for symptomatic, haemodynamically significant, RAS has become the preferred method of revascularization. Balloon angioplasty has been the traditional treatment of choice for fibromuscular dysplasia, however stents are increasingly used for the treatment of atheromatous lesions; in many cases-such as in ostial lesions-, direct stenting is strongly indicated. Despite the increased use of endovascular therapy for renal artery stenosis, there is still controversy regarding the optimal management and the net benefit of this treatment. Several randomized trials of balloon angioplasty or stenting for renal artery stenosis compared with medical therapy alone have been conducted, however these could not show definite advantage of endovascular therapy. Problems encountered with those trials include enrollment of small number of patients, frequent crossover from medical to interventional therapy compromising the intention-to-treat results, or selection of patients that are not expected to show clear benefit. The Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) is the most important of these trials; however, it,s study design was faulty and therefore did not provide conclusive evidence to answer the question of whether angioplasty and stenting or medical therapy is the best treatment for haemodynamically significant RAS. All expectations are now focused on the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) trial which was designed to answer the same question, and its methodologies took into consideration the weaknesses of the ASTRAL trial. Regarding stent device itself, it seems that the optimal design is probably a stainless steel, laser cut, open-cells stent mounted on a rapid exchange delivery balloon catheter compatible with 0.014-in and 0.018-in guidewire.

    Full Text Available En fútbol, el patrón de actividad de jugadores adultos, tanto masculinos como femeninos, ha sido ampliamente estudiado, pero son escasos los estudios que han centrado su atención en el análisis de los desplazamientos de los jugadores de categorías infantiles. Un mayor conocimiento de las demandas de este deporte en las etapas iniciales permitiría la confección de programas de entrenamiento más acordes con las características de los chicos de estas edades. El objetivo del presente estudio fue cuantificar de los desplazamientos en jugadores de fútbol de categoría infantil (12,2 ± 0,6 años; 156 ± 0,8 cm y 51 ± 5,2 kg que pertenecían a la selección de la ciudad autónoma de Melilla, mediante la aplicación de dispositivos basados en tecnología GPS. Los resultados obtenidos certifican que el fútbol infantil es una especialidad deportiva intermitente en la que se intercalan actividades de alta intensidad con situaciones del juego que permiten que el jugador recupere estando parado, andando o con una velocidad de carrera muy baja. La tasa trabajo-descanso fue de 1:3,5 y la distancia media recorrida por minuto fue aproximadamente de 100 m. Esta distancia varía disminuyendo de forma lineal conforme transcurre el partido, existiendo diferencias significativas entre el inicio y el final del juego, lo que indicaría la aparición de la fatiga. Los esfuerzos de alta intensidad que se realizan implican el 6,1% del tiempo de juego y el 16,3 % de la distancia recorrida, efectuando un sprint máximo de entre 10 y 15 m de media, cada 141 segundos. La aplicación de tareas que reproduzcan la intensidad del juego durante cortos periodos de tiempo (no superiores a 10 minutos aseguraría una elevada intensidad de trabajo durante los entrenamientos.

Foram utilizadas informações de artigos publicados em revistas científicas, teses e publicações de organizações internacionais. O crescimento infantil se constitui em um dos melhores indicadores de saúde da criança e o retardo estatural representa atualmente, a característica antropométrica mais representativa do quadro epidemiológico da desnutrição no Brasil. Ressaltando a importância do fator genético no crescimento, a revisão abrange com maior ênfase a atuação dos fatores extrínsecos, sabendo-se que o processo de crescimento resulta da interação entre a carga genética e os fatores do meio ambiente, os quais premitirão a maior ou menor expressão do potencial genético. Face a comprovada natureza multicausal do crescimento infantil, vários estudos têm sido desenvolvidos, buscando relacionar variáveis biológicas, socioeconômicas, maternas, ambientais, culturais, demográficas, nutricionais, entre outras, com a sua etiologia, seu desenvolvimento e sua manutenção. A revisão apresentada reforça o interesse em investigações sobre o crescimento na primeira infância que devem ser permanentes, devido, principalmente, às repercussões a longo prazo sobre a saúde infantil.This review focuses on factors interfering with growth during the first years of life. Information was collected from articles published in indexed scientific journals, theses, technical books and publications of international organizations. Infant growth is one of the best health indicators, and linear growth retardation is currently the most representative anthropometric characteristic of child nutrition epidemiology in Brazil. The review indicates the value of genetics in growth, focusing, however on the influence of the extrinsic factors.

    Full Text Available The response of radiation-induced fibrosarcoma1 (RIF-1 tumors treated with the vascular-disrupting agent (VDA ZD6126 was assessed by in vivo and ex vivo1H magnetic resonance spectroscopy (MRS methods. Tumors treated with 200 mg/kg ZD6126 showed a significant reduction in total choline (tCho in vivo 24 hours after treatment, whereas control tumors showed a significant increase in tCho. This response was investigated further within both ex vivo unprocessed tumor tissues and tumor tissue metabolite extracts. Ex vivo high-resolution magic angle spinning (HRMAS and 1H MRS of metabolite extracts revealed a significant reduction in phosphocholine and glycerophosphocholine in biopsies of ZD6126-treated tumors, confirming in vivo tCho response. ZD6126-induced reduction in choline compounds is consistent with a reduction in cell membrane turnover associated with necrosis and cell death following disruption of the tumor vasculature. In vivo tumor tissue water diffusion and lactate measurements showed no significant changes in response to ZD6126. Spin-spin relaxation times (T2 of water and metabolites also remained unchanged. Noninvasive 1H MRS measurement of tCho in vivo provides a potential biomarker of tumor response to VDAs in RIF-1 tumors.

    Full Text Available USP15 is a deubiquitinase that negatively regulates activation of naive CD4+ T cells and generation of IFN-γ-producing T helper 1 (Th1 cells. USP15 deficiency in mice promotes antitumor T cell responses in a transplantable cancer model; however, it has remained unclear how deregulated T cell activation impacts primary tumor development during the prolonged interplay between tumors and the immune system. Here, we find that the USP15-deficient mice are hypersensitive to methylcholantrene (MCA-induced fibrosarcomas. Excessive IFN-γ production in USP15-deficient mice promotes expression of the immunosuppressive molecule PD-L1 and the chemokine CXCL12, causing accumulation of T-bet+ regulatory T cells and CD11b+Gr-1+ myeloid-derived suppressor cells at tumor site. Mixed bone marrow adoptive transfer studies further reveals a T cell-intrinsic role for USP15 in regulating IFN-γ production and tumor development. These findings suggest that T cell intrinsic USP15 deficiency causes excessive production of IFN-γ, which promotes an immunosuppressive tumor microenvironment during MCA-induced primary tumorigenesis.

    Renal colic in pregnant women is a serious condition, mainly when is associated with fever. Our retro-prospective study analyzes 111 cases managed conservatively or with endourological procedures for renal colic--insertion of JJ stents and percutaneous nephrostomy. Clinical evolution determined the insertion of JJ stents in 60 cases and the failure of this procedure imposed percutaneous nephrostomy in 5 cases. In 56 cases urinary tract infection was associated and in 2 cases, despite all efforts, the patients deceased due to sever sepsis. The immediate drainage of the upper urinary tract for renal colic in pregnancy is the recommended treatment, especially when the pain is associated with fever. JJ stens were well tolerated, even when they were replaced after 3 months. Pregnant women with a history of UTI or stone disease should be carefully followed-up.

    A total of 174 patients underwent simple nephrectomy in case of clinically operable kidney cancer without demonstrable metastases. Of these 85 received preoperative irradiation to the kidney and the regional lymph nodes (3000-4000 rad in 3-4 weeks). Prognosis was not influenced by preoperative irradiation. The preoperatively assessable prognostic criteria were sex and sedimentation rate: ESR >= 30 and being male worsened prognosis. The clinical T-categories of the UICC were not related to prognosis. Of the microscopic examination of the nephrectomy specimen, renal vein invasion and to a lesser extent a low degree of differentiation appeared to worsen prognosis. The prognostic influence of the P-categories was caused by a higher incidence of renal vein involvement in case of higher P-category. The most important prognostic factors - ESR, renal vein involvement, and sex - were not interrelated. Elective chemotherapy, radiation therapy, and hormone therapy could be considered in certain high-risk groups. (orig.)

    Scintigraphy is useful for monitoring perfusion and function of renal transplant, as well as for diagnosing miscellaneous surgical. This non-invasive imaging technique, which uses no deleterious products, is an attractive alternative for patients. This is especially true for those patients in early post-transplant course, with immunity depression and often impairment of renal function. Otherwise, multiple indices with a large range of inter-patient values has not favoured a methodological and interpretative consensus. Furthermore, the poor specificity of renogram patterns does not allow for discrimination of all etiologies with only one scintigraphy. Nevertheless, follow-up with iterative scintigraphy may be helpful due to the high intra-patient reproducibility and to the early appreciate change of parameters, according to clinical and histological renal post-transplant outcome.

    Full Text Available Leiomyosarcomas are rare malignant tumors of the kidney. They may arise from the renal capsule, renal vein, renal pelvic musculature or renal parenchyma. Renal pelvis is an uncommon site of occurrence, with around 10 cases reported in the literature so far. Here we present a 60-year-old male who presented with increased urinary frequency, lower limb weakness, anorexia and weight loss. Imaging showed a right renal mass. A renal cell carcinoma was suspected clinically. A right nephrectomy was performed, which showed a large circumscribed mass in the hilar region. Histology revealed a tumor mass arising from the renal pelvis. The tumor was composed of spindle cells arranged in fascicles. Immunohistochemistry showed tumor cells to be positive for smooth muscle actin (SMA and desmin (Des and negative for cytokeratin (CK, HMB 45, CD117 (C-kit, and CD34. That confirmed the diagnosis of leiomyosarcoma.

  20. Renal denervation and hypertension.

    Schlaich, Markus P; Krum, Henry; Sobotka, Paul A; Esler, Murray D

    2011-06-01

    Essential hypertension remains one of the biggest challenges in medicine with an enormous impact on both individual and society levels. With the exception of relatively rare monogenetic forms of hypertension, there is now general agreement that the condition is multifactorial in nature and hence requires therapeutic approaches targeting several aspects of the underlying pathophysiology. Accordingly, all major guidelines promote a combination of lifestyle interventions and combination pharmacotherapy to reach target blood pressure (BP) levels in order to reduce overall cardiovascular risk in affected patients. Although this approach works for many, it fails in a considerable number of patients for various reasons including drug-intolerance, noncompliance, physician inertia, and others, leaving them at unacceptably high cardiovascular risk. The quest for additional therapeutic approaches to safely and effectively manage hypertension continues and expands to the reappraisal of older concepts such as renal denervation. Based on the robust preclinical and clinical data surrounding the role of renal sympathetic nerves in various aspects of BP control very recent efforts have led to the development of a novel catheter-based approach using radiofrequency (RF) energy to selectively target and disrupt the renal nerves. The available evidence from the limited number of uncontrolled hypertensive patients in whom renal denervation has been performed are auspicious and indicate that the procedure has a favorable safety profile and is associated with a substantial and presumably sustained BP reduction. Although promising, a myriad of questions are far from being conclusively answered and require our concerted research efforts to explore the full potential and possible risks of this approach. Here we briefly review the science surrounding renal denervation, summarize the current data on safety and efficacy of renal nerve ablation, and discuss some of the open questions that need

    We report the imaging findings in 11 patients with infantile neuroaxonal dystrophy. Ten patients underwent 15 MRI examinations; one patient had only CT. Of the ten patients who underwent MRI, eight had cerebellar atrophy and mildly increased signal from the cerebellar cortex on T2-weighted images. With T2 weighting there was slightly increased signal from the dentate nuclei in two patients and from the posterior periventricular white matter in three. We saw four patients with a thin optic chiasm. The only two brothers in the series had markedly low signal from the globus pallidus and substantia nigra on 1.5 T T2-weighted images, as seen in Hallervorden-Spatz disease (HSD). Abnormalities of the globus pallidus may be related to a protracted course of the disease. However, an overlap with HSD should be considered. (orig.) With 3 figs., 1 tab., 28 refs.

    Infantile hemangiomas (IH) at risk for complications need to be recognized early. We sought to determine if parents are able to assess, after e-learning, whether their child has an IH, is at risk for complications, and needs to be seen (urgently) by a specialist. This was a prospective study of 158 parents participating in an IH e-learning module. Parents were asked to assess their child's skin abnormality. A dermatologist answered the same questions (by e-consult). The 2 assessments were compared. Parents showed a 96% concordance with the dermatologist for correct diagnosis after e-learning. Concordances were 79%, 75%, and 84% (P e-learning module. E-learning by parents could result in earlier presentation and treatment of high-risk IH.

    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.

    Lobar emphysema is an uncommon cause of respiratory distress in infancy. Congenital heart disease is seen in about 20% of the patients with infantile (congenital) lobar emphysema. We described six infants with lobar emphysema. In three of them a congenital heart disease was demonstrated by cardiac catheterization and cineangiography; two had a tetralogy of Fallot with right aortic arch and the third infant a ventricular septal defect. The pulmonary angiography showed stretching of the arteries with very poor filling of the peripheral arteries and a characteristic smaller pulmonary vein in the affected lobe. In all the six patients the pulmonary artery pressure was normal. All the patients underwent lobectomy with good results. We feel that a preoperative cardiac catheterization and cineangiography is of value in this very sick group of infants.

    We report infantile subdural hematoma caused by abuse. Between January 2006 and December 2009, 10 cases of definite and highly suspicious abusive subdural hematoma in infants were treated at Nara Medical University Hospital. The mean age was 5.4 months. On CT examination, severe cerebral swelling was seen in 8 (80%) and wide spreading cerebral ischemia and atrophy in 9 (90%). Retinal hemorrhage was commonly seen in this series (90%). Subdural drainage and/or subdural-peritoneal shunt surgeries were performed in 6 cases, and intensive combined therapy of mild hypothermia and barbiturate was adapted in 7 cases. Favorable outcome was achieved in only 3 cases. In spite of aggressive treatment, clinical outcome are still bad. In our series, assailants were predominantly not father but mother. There were various and complex factors for child abuse. Cautious insight and suspicion are necessary to detect abusive injuries in infants. It is very important to endeavor to prevent recurrences of abusive injuries. (author)

    Full Text Available The diagnosis of child maltreatment leading to head injury is challenging. Here, we present the case of a 3-month-old female infant who presented with focal seizures that lasted for several minutes. After admission, she began to show intermittent clusters of head nods, irritable crying, arching, writhing, stiffening, and jerking of both arms. These results and electroencephalography findings were attributed as the diagnosis of infantile spasms (IS. Brain computed tomography and magnetic resonance imaging (MRI revealed the presence of chronic subdural hematoma mixed with acute ischemic injuries. Examination of the eye fundus confirmed the presence of retinal hemorrhage. Therefore, all evidence pointed to a diagnosis of shaken baby syndrome (SBS. Based on this case, we suggest that physicians should consider a diagnosis of SBS for children with new-onset IS and that should be evaluated, diagnosed, and treated as promptly as possible.

    The first years of life are typically shrouded by infantile amnesia, but there is enormous variability between adults in how early and how much they can remember from this period. This study examined one possible factor affecting this variability: whether the perceived quality of parent-child relationships is associated with the number of early memories young adults can retrieve, and their age at the time of their first memory. We found such associations but they were qualified by parent gender. Mother-child relationships that were more affectively intense (greater social support but also more negative interchanges) were associated with recalling more early memories, although paternal companionship was most associated with how early an individual's first memory was. Affective tone of retrieved memories was also assessed, and a greater proportion of affectively positive memories (as well as fewer affectively neutral memories for males) was associated with high parental involvement in children's lives.

    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.

    Background: Renal leiomyomas are rare benign tumors of the kidney which can be found at autopsy as small capsular nodules in about 5% of cases. The clinical incidence of such lesions is much smaller, and only case reports or small series have been reported in the imaging literature. Purpose: To describe the imaging characteristics observed in a series of eight patients with pathology-proven asymptomatic leiomyomas of the kidney. Material and Methods: We reviewed the imaging findings observed in eight patients with pathologically proven asymptomatic renal leiomyomas discovered during studies performed for reasons unrelated to the kidney. All patients had undergone computed tomography (CT), two ultrasonography, and one magnetic resonance imaging (MRI). Results: Lesions ranged in size from 1.2 to 13 cm. Six were at the periphery of the kidney, compressed its outer surface, but did not cause disruption of the cortex; two involved the renal cortex. All had regular outer margins. A cleavage plane between the tumor and the kidney was revealed at CT and/or ultrasonography in three of the cases located at the periphery. At ultrasonography, leiomyomas appeared hypoechogenic. At CT, they were slightly hyperdense before contrast medium injection; all were hypodense to the renal cortex after contrast medium. Four were homogeneous, two were slightly heterogeneous, and the remaining two were frankly heterogeneous. The lesion studied by MRI, which was homogeneous at the postcontrast CT study, had a heterogeneous structure on both T1- and T2-weighted images, with internal areas of hypointensity on T1. Conclusion: There are some imaging findings that can help to suggest the diagnosis of renal leiomyomas. First, their density: all tumors examined before contrast were hyperdense to the kidney, with density similar to that of muscles, and all had lower enhancement than the adjacent renal parenchyma. Second, the location and margins of the tumors: most were peripheral, without

    Metodi: presso l’Archivio Storico del Comune di Ferrara sono conservati i registri di morte dal 1813 al 1902 della popolazione ebraica da cui si sono tratte le seguenti variabili: anno di morte, numero progressivo del registro, cognome e nome del deceduto, sesso, giorno e mese di morte, malattia o causa di morte, età alla morte (mesi, giorni, ore. Il sesso è desunto dal nome del deceduto. Come in precedenti lavori, il nostro gruppo di ricerca, per definire la classificazione delle cause di morte nel primo anno di vita ha utilizzato fino all’anno 1854 un lavoro di Silini G. basato sulle metodologie di studio delle cause di morte nel secolo XIX a Lovere (Bergamo adattandola al diverso contesto storico geografico. Per il periodo successivo si è adottato il criterio classificatorio ISTAT (IX revisione.

Los efectos de este problema repercuten notablemente en aquellos que sobreviven, ya que las consecuencias a largo plazo del maltrato infantil son más perjudiciales para lasvíctimas y sus familias, y más costoso para la sociedad, que las lesiones agudas inmediatas que puedan producir. Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally. Within these, child abuse has alarming figures. This is the subject of this review.

    Full Text Available Las películas animadas infantiles pueden contribuir al desarrollo de la capacidad humana de sentir y manifestar emociones, de acuerdo a la postura de Nussbaum (2001a. En este trabajo se analiza la emoción de la compasión en dos películas animadas infantiles de la compañía Disney Pixar: Toy Story de 1995 y Up de 2009. Se enfatiza una postura cognitivaevaluativa sobre las emociones, la cual afirma que la manifestación emocional se basa en creencias o presupuestos que los humanos construyen sobre lo que los rodea. Esta postura admite que las emociones pueden ser aprendidas y por lo tanto es posible pensar que los medios de comunicación participan en este aprendizaje. Para el análisis se identificaron los contenidos donde estuviera presente la compasión y se analizó con la ayuda de un modelo aquí propuesto, que conjunta la secuencia motivadora de Monroe y Enhinger (1969 y los juicios cognitivos de Aristóteles (2002, revisados por Nussbaum (2001a. El análisis de las películas muestra que la compasión se manifiesta en palabras, acciones y expresiones faciales de los personajes. Es posible que el niño espectador aprenda a través de los ejemplos mostrados cuál es la adecuada manifestación de esta emoción y la manera de reaccionar, como por ejemplo brindar palabras de consuelo a quien sufre. Sin embargo es necesario propiciar en los niños una actitud crítica que les permita identificar sesgos o reacciones inadecuadas, de manera que lo observado proporcione elementos valiosos para su relación con los demás y para su propio desarrollo emocional.

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (HRS) is a unique form of renal failure associated with advanced liver dise...

    1982-01-01

    Transplantable 7,12-dimethylbenz[a]anthracene-induced SC chicken fibrosarcoma (CHCT-NYU) lines were studied for their ability to grow in internal organs after iv injection (artificial metastases) into 1- to 3-week-old chickens. Some tumor lines were recently derived, whereas others were studied after many serial subcutaneous transplantations. Artificial metastases were seen in the stomach, pancreas, lungs, heart, and muscle, and occasionally in the kidneys and liver. Agammaglobulinemic recipients showed more extensive organ involvement than normal recipients of the same age. Whole-body ν-irradiation enhanced the incidence of artificial metastases, particularly in lungs. Antibody from the serum of a primary tumor-bearing host reduced the growth of the corresponding tumor in many organs. The metastatic pattern of line CHCT-NYU4 was a relatively stable property. However, intravenous transplantation of tumor cells from line CHCT-NYU4 taken from the liver, lungs, and pancreas of a single recipient established sublines with changes in organ specificity. After a few such serial transplants of liver-derived tumor, a line was derived that grew virtually in the liver alone. A subline with preference for growth in lungs was also obtained, but its ability to grow in the pancreas persisted. A pancreas-derived tumor line also grew in the liver and lungs. Subcutaneous transplants of tissue fragments of the lung-derived tumor line caused the appearance of spontaneous metastases in lungs. The incidence of spontaneous metastases with the lung-derived line was much greater than that with the liver-derived line or with the original CHCT-NYU4 line

    Few birth cohort studies have examined the role of traffic-related air pollution (TRAP) in the development of infantile atopic dermatitis (AD), but none have investigated the role of preventive factors such as green spaces. The aim of this study was to investigate whether exposure to nitrogen dioxide (NO₂) and particulate matter with an aerodynamic diameter of Health study. Subjects were geocoded to their residential addresses and matched with air pollution data modeled using land-use regression. Information on infantile AD was obtained by using a questionnaire administered to the parents or guardians of the children. The association between infantile AD and exposure to NO₂ and PM 10 was determined using logistic regression models. We assessed the effects of residential green spaces using stratified analyses and by entering product terms into the logistic regression models. The risk of infantile AD significantly increased with an increase in air pollution exposure during the first trimester of pregnancy. The adjusted odds ratio (OR) and 95% confidence interval (CI) were 1.219 (1.023-1.452) per 10 μg/m³ increase in PM 10 and 1.353 (1.027-1.782) per 10 ppb increase in NO₂. An increase in the green space within 200 m of residence was associated with a decreased risk of AD (OR = 0.996, 95% CI: 0.993-0.999). The stratified analysis of residential green space revealed stronger associations between infantile AD and PM 10 and NO₂ exposure during the first trimester in the areas in the lower tertiles of green space. This study indicated that exposure to TRAP during the first trimester of pregnancy is associated with infantile AD. Less residential green space may intensify the association between TRAP exposure and infantile AD.

    Infantile and late infantile neuronal ceroid lipofuscinoses (NCLs) are lysosomal storage diseases affecting the central nervous system (CNS). The infantile NCL (INCL) is caused by mutations in the PPT1 gene and late-infantile NCL (LINCL) is due to mutations in the TPP1 gene. Deficiency in PPT1 or TPP1 enzyme function results in lysosomal accumulation of pathological lipofuscin-like material in the patient cells. There is currently no small-molecular drug treatment for NCLs. We have generated induced pluripotent stem cells (iPSC) from three patient dermal fibroblast lines and further differentiated them into neural stem cells (NSCs). Using these new disease models, we evaluated the effect of δ-tocopherol (DT) and hydroxypropyl-β-cyclodextrin (HPBCD) with the enzyme replacement therapy as the control. Treatment with the relevant recombinant enzyme or DT significantly ameliorated the lipid accumulation and lysosomal enlargement in the disease cells. A combination therapy of δ-tocopherol and HPBCD further improved the effect compared to that of either drug used as a single therapy. The results demonstrate that these patient iPSC derived NCL NSCs are valid cell- based disease models with characteristic disease phenotypes that can be used for study of disease pathophysiology and drug development.

O caso ‘sobrepeso e obesidade’ é tratado por muitas pessoas sem a devida importância, por entenderem que o mesmo é apenas uma questão estética que não interfere em nada além da saúde física da criança obesa ou sobrepesada, o que é um engano, pois a obesidade e o sobrepeso tem várias causas e uma extensão de problemas, como a hipertensão e o diabetes entre outros, que estão associados direta ou indiretamente a esse mal. A pesquisa foi realizada com crianças de 4 a 5 anos, de uma escola pública e uma privada do município de Sinop - MT, tendo como respaldo metodológico a observação participante utilizando-se de questionários implícitos em diálogos, onde tivemos a oportunidade de compreender alguns aspectos sobre os hábitos alimentares e físicos das mesmas. Os diálogos foram analisados de forma qualitativa, onde munidos do índice de massa corporal, caderno de impressões, podemos constatar que o maior mal que a obesidade causa é o psicológico, pois as crianças sobrepesadas observadas se excluem do convívio social. Aos responsáveis e sociedade em geral cabe a responsabilidade de dar continuidade aos saberes aplicados em sala, estabelecendo hábitos mais saudáveis no ambiente em que vivem.Palavras-chave: educação; educação física e alimentar; obesidade infantil; alunos de 4 e 5 anos.

    Full Text Available La Organización Mundial de la Salud ( OMS ha catalogado la obesidad infantil como la mayor crisis de la salud pública en el mundo. En su informe de 2014 indica que se registraron cuarenta y dos millones de niños menores de 5 años con sobrepeso; de ellos, treinta y cinco millones viven en países en desarrollo. La obesidad infantil es una enfermedad que tiene como origen una cadena causal compleja, de etiología multifactorial, en la que interactúan factores individuales y contextuales; en ellos el niño se encuentra inmerso, y ejercen influencia sobre su comportamiento, en diversos entornos y en diferentes niveles de jerarquía. Esta revisión presenta una descripción de algunos estudios y esfuerzos realizados para carac - terizar, prevenir y controlar la epidemia de obesidad en esta etapa del ciclo vital. Se propone, así mismo, un abordaje para el estudio de la obesidad, denominado ‘Enfoque de sistemas complejos’, el cual permite analizar cómo los factores individuales y contextuales se relacionan, y cómo esa interacción genera nuevas propiedades que no pueden explicarse a partir de los procedimientos habituales de análisis epidemiológico; para ello será necesario el trabajo en equipo, con enfoque multidisciplinario, que incluya médicos, pediatras, nutricionistas, epidemiólogos, salubristas, estadísticos, ingenieros, entre otros profesionales, que aporten sus conocimientos y habilidades, que permitan entender la obesidad como un fenómeno dinámi - co que requiere ser abordado con un enfoque integral e integrador, que trascienda la mirada reduccionista de los factores de riesgo del proceso salud – enfermedad. Solo entonces se podrá mejorar la capacidad para comprender la salud desde una perspectiva clásica hasta un sistema verdaderamente dinámico.

    The purpose of this study is to determine characteristic CT findings in renal abscess. Twenty cases of renal abscess were retrospectively analyzed for CT findings relating to the shape and extent of the abscess, change of nephrogram, peripheral rim enhancement, wedge-shaped enhancement on delayed scans, enlargement of the kidney involved and associated findings. Seven patients had a renal abscess at the right kidney, nine at the lift kidney and two bilaterally. The abscesses were round in 18 cases and finger-like in two. Rim enhancement around renal abscess was seen in four cases (20%). Changes in the nephrogram around the abscess were seen in 12 cases (60%). In all six patients who had undergone delayed postcontrast scans, wedge-shaped enhancement was shown around the abscess (100%). In the observation of the extent of renal abscesses, 14 cases were within the kidney, six cases extended the beyond renal capsule, and two were loculated in the renal fascia itself. Renal enlargement was seen in nine cases (45%). These results suggest that CT findings such as delayed wedge-shaped enhancement, change of nephrogram, peripheral rim enhancement, renal enlargement, and associated findings are valuable for diagnosis, and that CT also gives information concerning the extent, evolution and complication of a renal abscess

    Background Visceral leishmaniasis (VL) was once a severe parasitic disease in China. Thanks to the great efforts of integrated control, VL was eliminated in most epidemic areas, except for certain western provinces (autonomous region) at the end of 1950s. From then on, VL gained less attention and has seemed to spread, especially in the last 15 years. Infants are the most important population threatened by VL. However, there have been few studies on the endemic characteristics of infantile VL in China. Methods Infantile VL cases were collected from the online National Infectious Diseases Reporting System (NIDRS). Statistical description and inference was used to reveal the endemic characteristics in gender, age group, time and regionalism. Spatial analysis was carried out to explore the high risk area for infantile VL in China. Results A total of 1093 infantile VL cases were reported from 2006 to 2012. There was no statistically significant difference in gender over time. The minimum, maximum and mean age of these cases was 1.1, 35.9 and 13.8 months, respectively. Among them 86.92% were under 2 years of age, and there was a statistically significant difference among age groups over time. An incidence peak appeared in 2008-2009, most cases were distributed in the months September to December, and there was a tail-raising effect in the coming two months of the next year. More than 98% of cases were reported in Xinjiang Uygur Autonomous Region, Gansu Province and Sichuan Province, accounting for 61.02%, 32.75% and 4.57%, respectively. A total of 56 counties reported infantile VL cases, with the cumulative incidence ranging from 0.02 to 24.57%. There were two main zones of high endemicity for infantile VL in China. The monthly incidence clearly coincides with the number of towns where infantile VL cases were reported. Three fatalities were reported during the study period, the case fatality rate was 2.75‰.

Infantile amnesia is the term used to describe this phenomenon of accelerated forgetting during infancy, and it is not unique to humans. Over the years, information garnered from animal studies has provided clues as to the neurobiological basis of infantile amnesia. The purpose of this review is to provide a neurobiological update on what we now know about infantile amnesia since the publication of Campbell and Spear's seminal review on the topic more than 40 years ago. We present evidence that infantile amnesia is unlikely to be explained by a unitary theory, with the protracted development of multiple brain regions and neurotransmitter systems important for learning and memory likely to be involved. The recent discovery that exposure to early life stress can alleviate infantile amnesia offers a potential explanation as to how early adversity can so profoundly affect mental health in adulthood, and understanding the neurobiological basis for this early transition may lead to the development of effective therapeutic interventions.

    Infantile masturbation is considered a variant of normal behaviour. The abrupt and spontaneous onset, altered sensorium and autonomic phenomena during episodes may suggest an epileptic fit. Therefore, children with infantile masturbation are often admitted to hospital and undergo unnecessary tests. The purpose of the present study was to provide a detailed description of hand activities in infantile masturbation. The authors reviewed video recordings of 2 boys and 11 girls with infantile masturbation. Position, movements and activities of hands and fingers during episodes were registered. Five patterns of hand activities were registered: Fisting (four infants), grasping of toys, furniture or clothing (ten infants), chorea-like "piano playing" hand movements (two infants), pressure over the diaper/genital region (one infant) and bimanual manipulation of items (four infants). Fisting was primarily observed in the younger infants, and bimanual manipulation was primarily seen in the older infants. Recognizing one or more of the five distinct patterns of hand activities in infantile masturbation may help establishing the diagnosis.

    Immature teratoma (IMT) is the most frequent histological subtype of infantile intracranial teratoma, the most common congenital brain tumor. IMT contains incompletely differentiated components resembling fetal tissues. Infantile intracranial IMT has a dismal prognosis, because it is often inoperable due to its massive size and high vascularity. Neoadjuvant chemotherapy has been shown to be effective in decreasing tumor volume and vascularity to facilitate surgical resection in other types of infantile brain tumors. However, only one recent case report described the effectiveness of neoadjuvant chemotherapy for infantile intracranial IMT in the literature, even though it is common entity with a poor prognosis in infants. Here, we describe the case of a 2-month-old male infant with a very large intracranial IMT. Maximal surgical resection was first attempted but was unsuccessful because of severe intraoperative hemorrhage. Neoadjuvant carboplatin and etoposide (CARE) chemotherapy was then administered with the aim of shrinking and devascularizing the tumor. After neoadjuvant chemotherapy, tumor size did not decrease, but intraoperative blood loss significantly decreased and near-total resection was achieved by the second and third surgery. The patient underwent adjuvant CARE chemotherapy and has been alive for 3 years after surgery without tumor regrowth. Even when neoadjuvant chemotherapy does not decrease tumor volume of infantile intracranial IMT, surgical resection should be tried because chemotherapy can facilitate surgical resection and improve clinical outcome by reducing tumor vascularity.

    Osteopetrosis is a rare hereditary metabolic bone disorder characterized by generalized skeletal sclerosis caused by a defect in bone resorption and remodelling. Infantile autosomal recessive osteopetrosis is one of three subtypes of osteopetrosis and the most severe form. The correct and early diagnosis of infantile osteopetrosis is important for management of complications and for future genetic counselling. Diagnosis is largely based on clinical and radiographic evaluation, confirmed by gene testing where applicable. Therefore, in this case study the classical clinical and radiological signs of a boy with infantile osteopetrosis will be presented with a comprehensive literature update. The differentiating signs from other causes of hereditary osteosclerosing dysplasias are discussed. This case study and review of available literature show that there tends to be a highly unique clinical and skeletal radiographic pattern of affection in infantile osteopetrosis. Although tremendous advances have been made in the elucidation of the genetic defect of osteopetrosis over the past years, the role of accurate clinical and radiological assessment remains an important contributor to the diagnosis of infantile osteopetrosis.

    Food allergies (FAs) are an increasing problem in Western countries, affecting up to 10% of young children. FAs are frequently associated with gastrointestinal manifestations. The role of FAs as a potential causative factor for infantile colic (IC) is still controversial. We report the most recent evidence on the pathogenesis, clinical and diagnostic aspects of FA-induced infantile colic (IC) and suggest a stepwise diagnostic approach. We selected articles on clinical and immunologic features, pathogenesis and management of FAs and IC from of 1981 to 2015. Original and review articles were identified through selective searches performed on PubMed, using the following terms: colic, infantile colic, food allergy and infantile colic, infantile colic treatment. The possible relationship between FAs and IC derives from the presence of dysmotility with visceral hypersensitivity and dysbiosis, demonstrated in both conditions, and the clinical response to dietary interventions. Unfortunately, the design of the studies, poor characterization of atopy and different dietary approaches limit the understanding of the importance of FAs in subjects with IC. The role of FAs in IC subjects without other symptoms of atopy remains controversial. However, where there is a suspicion of FAs, a short trial with an extensively hydrolyzed cow's proteins formula or, if breast fed, with maternal elimination diet may be considered a reasonable option.

    The goal of this study was to examine the relative contributions of growth deficiency and psychosocial factors to cognitive development in toddlers with infantile anorexia. Eighty-eight toddlers, ranging in age from 12 to 33 months, were enrolled in this study. Toddlers were evaluated by 2 child psychiatrists and placed into 1 of 3 groups: infantile anorexia, picky eater, and healthy eater. All 3 groups were matched for age, race, gender, and socioeconomic status (SES). Toddlers underwent nutritional evaluations and cognitive assessments with the Bayley Scales of Infant Development. Toddlers and their mothers were also videotaped during feeding and play interactions, which later were rated independently by 2 observers. On average, toddlers with infantile anorexia performed within the normal range of cognitive development. However, the Mental Developmental Index (MDI) scores of the healthy eater group (MDI = 110) were significantly higher than those of the infantile anorexia (MDI = 99) and picky eater (MDI = 96) groups. Within the infantile anorexia group, correlations between MDI scores and the toddlers' percentage of ideal body weight approached statistical significance (r =.32). Across all groups, the toddlers' MDI scores were associated with the quality of mother-child interactions, SES level, and maternal education level. Collectively, these variables explained 22% of the variance in MDI scores. This study demonstrated that psychosocial factors, such as mother-toddler interactions, maternal education level, and SES level, are related to the cognitive development of toddlers with feeding problems and explain more unique variance in MDI scores than nutritional status.

  1. Contribution of Embodiment to Solving the Riddle of Infantile Amnesia

    Full Text Available At least since the late nineteenth century, researchers have sought an explanation for infantile amnesia (IA—the lack of autobiographical memories dating from early childhood—and childhood amnesia (CA, faster forgetting of events up until the age of about seven. Evidence suggests that IA occurs across altricial species, and a number of studies using animal models have converged on the hypothesis that maturation of the hippocampus is an important factor. But why does the hippocampus mature at one time and not another, and how does that maturation relate to memory? Our hypothesis is rooted in theories of embodied cognition, and it provides an explanation both for hippocampal development and the end of IA. Specifically, the onset of locomotion prompts the alignment of hippocampal place cells and grid cells to the environment, which in turn facilitates the ontogeny of long-term episodic memory and the end of IA. That is, because the animal can now reliably discriminate locations, location becomes a stable cue for memories. Furthermore, as the mode of human locomotion shifts from crawling to walking, there is an additional shift in the alignment of the hippocampus that marks the beginning of adult-like episodic memory and the end of CA. Finally, given a reduction in self-locomotion and exploration with aging, the hypothesis suggests a partial explanation for cognitive decline with aging.

    Infantile onset diabetes mellitus (IODM) is an uncommon metabolic disorder in children. Infants with onset of diabetes mellitus (DM) at age less than one year are likely to have transient or permanent neonatal DM or rarely type 1 diabetes. Diabetes with onset below 6 mo is a heterogeneous disease caused by single gene mutations. Literature on IODM is scanty in India. Nearly 83% of IODM cases present with diabetic keto acidosis at the onset. Missed diagnosis was common in infants with diabetes (67%). Potassium channel mutation with sulphonylurea responsiveness is the common type in the non-syndromic IODM and Wolcott Rallison syndrome is the common type in syndromic diabetes. Developmental delay and seizures were the associated co-morbid states. Genetic diagnosis has made a phenomenal change in the management of IODM. Switching from subcutaneous insulin to oral hypoglycemic drugs is a major clinical breakthrough in the management of certain types of monogenic diabetes. Mortality in neonatal diabetes is 32.5% during follow-up from Indian studies. This article is a review of neonatal diabetes and available literature on IODM from India. PMID:27022444

    Serum acetylcholinesterase (AChE) and pseudocholinesterase (ChE) activity in infantile and juvenile spinal muscular atrophy (SMA) was determined. The total AChE activity was either normal or decreased in the childhood SMA (Type 1), the other SMA groups and disease controls (ALS, X-linked SMA). In the majority of SMA Type 1 cases (6/7 tested) an absence of the asymmetric A12 form was found. This was accompanied by changes in the other asymmetric and globular forms. The latter was, however, not specific for SMA Type 1 cases. The ChE activity was increased in the majority of SMA cases as well as disease controls. The asymmetric A12 ChE form was increased in all SMA Type 3 cases, the values of this form in SMA Type 1 was variable. A change in the ChE globular forms in SMA Type 1 and SMA Type 2 was a frequent finding. It is suggested that the absence of the asymmetric A12 AChE form in SMA Type 1 arises because of muscle cell immaturity and undeveloped muscle-nerve interactions. The reason of ChE changes is obscure.

    Infantile-onset Pompe disease is a rare and progressive autosomal-recessive disorder caused by a deficiency of the lysosomal enzyme acid alpha-glucosidase (GAA). Current treatment involves enzyme replacement therapy (with recombinant human alglucosidase alfa) and symptomatic therapies (e.g. to control secretions). Children who are cross-reactive immunological material (CRIM)-negative require immunomodulation prior to commencing enzyme replacement therapy.Enzyme replacement therapy was developed as the most promising therapeutic approach for Pompe disease; however, the evidence is lacking, especially regarding the optimal dose and dose frequency. To assess the effectiveness, safety and appropriate dose regimen of enzyme replacement therapy for treating infantile-onset Pompe disease. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Inborn Errors of Metabolism Trials Register, which is compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the Cochrane Central Register of Controlled Trials (CENTRAL), Embase (Ovid), PubMed and LILACS, and CBM, CNKI, VIP, and WANFANG for literature published in Chinese. In addition, we searched three online registers: WHO International Clinical Trials Registry Platform ClinicalTrials.gov, and www.genzymeclinicalresearch.com. We also searched the reference lists of relevant articles and reviews.Date of last search of the Group's Inborn Errors of Metabolism Trials Register: 24 November 2016.

    Full Text Available Infantile nystagmus syndrome (INS is one of the leading causes of significant vision loss in children and affects about 1 in 1000 to 6000 births. In the present study, we are the first to investigate the structural pathways of patients and controls using diffusion tensor imaging (DTI. Specifically, three female INS patients from the same family were scanned, two sisters and a mother. Six regions of interest (ROIs were created manually to analyze the number of tracks. Additionally, three ROI masks were analyzed using TBSS (Tract-Based Spatial Statistics. The number of fiber tracks was reduced in INS subjects, compared to normal subjects, by 15.9%, 13.9%, 9.2%, 18.6%, 5.3%, and 2.5% for the pons, cerebellum (right and left, brainstem, cerebrum, and thalamus. Furthermore, TBSS results indicated that the fractional anisotropy (FA values for the patients were lower in the superior ventral aspects of the pons of the brainstem than in those of the controls. We have identified some brain regions that may be actively involved in INS. These novel findings would be beneficial to the neuroimaging clinical and research community as they will give them new direction in further pursuing neurological studies related to oculomotor function and provide a rational approach to studying INS.

    Full Text Available 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.

    The aetiology of infantile hypertrophic pyloric stenosis (IHPS) has not been fully elucidated. Since the 1990s, a sharp decline in IHPS has been reported in various countries. Recent research from Sweden reported a correlation between falling rates of IHPS and of sudden infant death syndrome (SIDS). This was attributed to a reduction in the number of infants sleeping in the prone position following the "Back to Sleep" campaign. To describe the changing epidemiology of IHPS in Scotland, to examine the relationship between IHPS and SIDS rates and to examine trends in other factors that may explain the observed reduction in IHPS incidence. Incidence rates of IHPS and SIDS were derived from routine data and their relationship analysed. Trends in mean maternal age, maternal smoking, mean birth weight and breastfeeding rates were also examined. The whole of Scotland between 1981 and 2004. IHPS incidence fell from 4.4 to 1.4 per 1000 live births in Scotland between 1981 and 2004. Rates were consistently higher in males, although the overall incidence patterns in males and females were similar. Rates showed a positive relationship with deprivation. The fall in the incidence of IHPS preceded the fall in SIDS by 2 years and the incidence of SIDS displayed less variability than that of IHPS. Significant temporal trends were also observed in other maternal and infant characteristics. There has been a marked reduction in Scotland's IHPS incidence, but this is unlikely to be a consequence of a change in infant sleeping position.

    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. Two checklists were used to evaluate the quality indicators of 24 Web sites and the colic-specific content. 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. 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.

    To evaluate the usefulness and complications of renal biopsy under ultrasonography-guidance in renal dysfunction after renal transplantation. Ultrasonography-guided renal biopsy was done in 47 patients with the transplanted kidney. The subjects consisted of 30 males and 17 females, age ranged from 16 to 66 years (average age=38 years). Biopsies were done once in 27 patients, twice in 17 patients, three times in 3 patients, a total of 70 biopsies. The success rate of renal biopsy for the accurate pathologic diagnosis and the incidence and types of complications following biopsy were evaluated. The success rate of renal biopsy for the accurate pathologic diagnosis was 96%(67/70). Pathologic diagnosis included 27 cases of acute rejection (39%), 8 cases of acute tubular necrosis (11%), 4 cases of acute rejection and acute tubular necrosis (6%), 4 cases of cyclosporin toxicity (6%), 4 cases of primary disease recurrence (6%), 4 cases of infection (6%) and others. Complications after renal biopsy included 15 cases of microscopic hematuria (21%), 1 case of gross hematuria with spontaneous cessation and 1 case of life threatening hemorrhage. Ultrasonography-guided renal biopsy is a safe and effective diagnostic method for the evaluation of renal dysfunction following renal transplantation.

    Renal angiomyoadenomatous tumour is a rare, recently described neoplasm with a distinctive histological appearance. Although reported in the pathology literature, to our knowledge, no prior reports have described its imaging appearance. We describe the computed tomography and magnetic resonance imaging features of an incidentally detected renal angiomyoadenomatous tumour that appeared as a well-marginated, solid T2-hypointense enhancing mass, in a 50-year-old woman. It is indistinguishable from a variety of benign and malignant renal neoplasms. PMID:23093565

    Renal oncocytoma, although rare, is being diagnosed more frequently, and criteria to differentiate it from other tumors have been described. Multiple oncocytomas have been reported, but an association between multiple oncocytomas and renal carcinoma in the same kidney has not been described. The authors report a case with two oncocytomas and a renal carcinoma in the right kidney as well as a right adrenal adenoma

    Purpose: To demonstrate the different patterns of renal infarction to avoid pitfalls. To present 'flip-flop enhancement' pattern in renal infarction. Materials and methods: Retrospective review of a total of 41 renal infarction in 37 patients were done. These patients underwent initial CT and the diagnosis of renal infarction was confirmed with either follow up CT or at surgery. Results: Twenty-three patients had wedge-shaped focal infarcts, nine patients had global and five patients had multifocal infarcts of the kidneys. Cortical rim sign was seen predominantly with global infarcts. In five patients, a 'flip-flop enhancement' pattern was observed. In two patients, planned renal biopsies due to tumefactive renal lesions were cancelled because of 'flip-flop enhancement' pattern on follow up CTs. Conclusion: Although most of our cases were straightforward for the diagnosis of renal infarction, cases with tumefactive lesions and global infarctions without the well-known cortical rim sign were particularly challenging. We describe a new sign, flip-flop enhancement pattern, which we believe solidified the diagnosis of renal infarction in five of our cases. The authors recommend further investigations for association of flip-flop enhancement and renal infarction

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    The changing trend in renal surgery, transplantation and minimal invasive urology implies preprocedure evaluation of renal veins. Development of imaging methods offers new possibilities for venographic visualization. The goal of this study is to present authors experience in visualization of renal veins using 64 MDCT and to evaluate the utility in assessments of their variants. 128 patients (68 females and 60 males, mean age 53,3) with urological complaints underwent 64MDCT examination including CT angiography. Contrast enhancement includes 3-4ml/sec injection flow of 90 ml contrast medium followed by 20 ml saline at the same rate. In 23 out of 128 examined patients some of the common variants of the renal vein is found. 64 MDCT angiography visualize very well renal veins and becomes method of choice in preoperative assessment of renal vein anatomy.

    This is a technique article discussing 3 alternative frames for casting children with infantile scoliosis. To provide surgeons with alternatives to expensive specialized casting tables to allow local treatment of these children utilizing readily available materials present at most institutions. Casting for infantile scoliosis has become more popular as reports have shown promising results with this technique without the morbidity and complications associated with more invasive procedures. However, without a specialized casting table, treating these patients has been limited to a few centers throughout the country often causing patients to travel large distances to receive care. Three different alternatives to commercially available casting frames are presented. Requirements, setup, and techniques are discussed. Each surgeon has had success with each of these frames. These provide adequate support and traction while allowing enough access to the trunk to apply a well-molded cast. Cotrel/Metha casting for infantile scoliosis can be accomplished without a specialized table using commonly available equipment.

    Purpose: To study the CT features of infantile cerebral vitamin B 1 deficiency. Methods: The authors retrospectively reviewed the clinical manifestations and CT findings of 22 cases of infantile vitamin B 1 deficiency. Results: The main clinical signs were seizure malaise dullness and vomiting. CT scans showed bilateral symmetrical hypodense foci in lenticular nucleus (20/22), head of caudate nucleus (15/22), thalamus (3/22), anterior limb of internal capsule (4/22), external capsule (1/22) and para-ventricle white matter (2/22), and in many cases, signs of cerebral atrophy. 22 cases received thiamine treatment and were fully recovered. Conclusion: The authors concluded that bilateral symmetric hypodense foci in lenticular nucleus thalamus, head of caudate nucleus, anterior limb of internal capsule, external capsule and para-ventricle white matter were important CT signs suggestive of infantile cerebral vitamin B 1 deficiency

  10. Infantile sexuality: Its place in the conceptual developments of Anna Freud and Donald W. Winnicott.

    Science.gov (United States)

    Joyce, Angela

    2016-06-01

    This essay explores the place of infantile sexuality in the theories of Anna Freud and Donald W Winnicott. Both Anna Freud and D.W. Winnicott incorporated and at the same time changed the classical psychoanalytic account of infantile sexuality and the instinctual drives. Whilst Anna Freud remained closer to her father's original conceptualization, she developed a multidimensional model of development which gave the drives a foundational status whist also maintaining their significance in giving meaning and texture to children's subjective experience. Winnicott also retained much of S. Freud's original theorizing except that in a fundamental way he turned it on its head when considering earliest development. For him the establishment of the self was paramount, and the drives and infantile sexuality merely served to give substance to that self. Copyright © 2016 Institute of Psychoanalysis.

    2014-01-01

    Full Text Available Pompe disease is a rare severe hereditary disease caused by excessive glycogen storage in organs and target tissues due to the acid α-glucosidase gene mutation. Infantile and adult Pompe disease is characterized by involvement of cardiovascular, respiratory and muscular systems in the pathological process. The only specific method of treating Pompe disease is enzyme replacement therapy (intravenous administration of recombinant human acid glucosidase, the effectiveness whereof depends on the time the therapy started. Since such a therapy was introduced into practice, Pompe disease mortality decreased by 79%. 6 children with infantile Pompe disease were observed and treated at the cardiovascular care unit of the Scientific Center of Children’s Health in 2011‑2014. The article presents a clinical case demonstrating capabilities of diagnosing infantile Pompe disease in Russia and effective application of alglucosidase alfa in 4-month-old child.

    Most patients with infantile-onset Pompe disease die in early infancy before beginning enzyme replacement therapy, which has made it difficult to evaluate the impact of Pompe disease on cognitive development. Patients with infantile-onset Pompe disease can survive with enzyme replacement therapy, and physicians can evaluate cognitive development in these patients. We established an effective newborn screening program with quick clinical diagnostic criteria. Cognitive and motor development were evaluated using the Bayley Scales of Infant and Toddler Development-Third Edition at 6, 12, and 24 months of age. The patients who were treated very early demonstrate normal cognitive development with no significant change in cognition during this period (P = .18 > .05). The cognitive development was positively correlated with motor development (r = 0.533, P = .011). The results indicated that very early enzyme replacement therapy could protect cognitive development in patients with infantile-onset Pompe disease up to 24 months of age. © The Author(s) 2016.

    With the greater frequency of renal transplant surgery, more female pts are becoming pregnant and carrying to term. In the renal allograft blood vessels and ureter may be compressed resulting in impaired renal function and/or, hypertension. Toxemia of pregnancy is seen more frequently than normal. Radionuclide renal scan monitoring may be of significant value in this high risk obstetrical pt. After being maintained during the pregnancy, renal function may also deteriorate in the post partum period. 5 pregnant renal transplant pts who delivered live babies had renal studies with Tc-99m DTPA to assess allograft perfusion and function. No transplanted kidney was lost during or after pregnancy as a result of pregnancy. No congenital anomalies were associated with transplant management. 7 studies were performed on these 5 pts. The 7 scans all showed the uterus/placenta. The bladder was always distorted. The transplanted kidney was rotated to a more vertical position in 3 pts. The radiation dose to the fetus is calculated at 0.024 rad/mCi administered. This study demonstrates the anatomic and physiologic alterations expected in the transplanted kidney during pregnancy when evaluated by renal scan and that the radiation burden may be acceptable in management of these pts

    2003-01-01

    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

    Full Text Available El citrato es un potente inhibidor de la cristalización de sales de calcio. La hipocitraturia es una alteración bioquímica frecuente en la formación de cálculos de calcio en adultos y especialmente en niños. El pH ácido (sistémico, tubular e intracelular es el principal determinante de la excreción de citrato en la orina. Si bien la mayoría de los pacientes con litiasis renal presentan hipocitraturia idiopática, hay un número de causas para esta anormalidad que incluyen acidosis tubular renal distal, hipokalemia, dietas ricas en proteínas de origen animal y/o dietas bajas en álcalis y ciertas drogas, como la acetazolamida, topiramato, IECA y tiazidas. Las modificaciones dietéticas que benefician a estos pacientes incluyen: alta ingesta de líquidos y frutas, especialmente cítricos, restricción de sodio y proteínas, con consumo normal de calcio. El tratamiento con citrato de potasio es efectivo en pacientes con hipocitraturia primaria o secundaria y en aquellos desordenes en la acidificación, que provocan un pH urinario persistentemente ácido. Los efectos adversos son bajos y están referidos al tracto gastrointestinal. Si bien hay diferentes preparaciones de citrato (citrato de potasio, citrato de sodio, citrato de potasio-magnesio en nuestro país solo está disponible el citrato de potasio en polvo que es muy útil para corregir la hipocitraturia y el pH urinario bajo, y reducir marcadamente la recurrencia de la litiasis renal.

    Full Text Available OBJETIVO: Avaliar a exposição da população infantil à FCA em nossa comunidade e sua relação com os sintomas de asma. MÉTODOS: Foi realizado um estudo transversal usando o questionário de estudo ISAAC em crianças e adolescentes da nossa comunidade. Pelo questionário, fez-se a definição por "já ocorreu sibilância", "asma atual", "asma grave" e "asma induzida pelo exercício". O tabagismo parental foi classificado em quatro categorias mutuamente excludentes: 1 nenhum dos pais fuma; 2 somente a mãe fuma; 3 somente o pai fuma; e 4 ambos os pais fumam. Calculou-se a odds ratio da prevalência de sintomas de asma, de acordo com a exposição à FCA, usando regressão logística. RESULTADOS: Foram incluídas, no total, 10.314 crianças e 10.453 adolescentes. Mais de 51% das crianças e adolescentes foram expostos à FCA em casa. A FCA se associa a uma prevalência mais alta de sintomas de asma, particularmente se a mãe ou ambos os pais fumam. CONCLUSÕES: A prevalência da FCA continua a ser alta em nossa comunidade, embora com uma tendência para diminuição nos últimos 15 anos. A FCA se associa a uma prevalência mais alta de asma.

    Cardiac rhabdomyoma is type of benign myocardial tumor that is the most common fetal cardiac tumor. Cardiac rhabdomyomas are usually detected before birth or during the first year of life. They account for over 60% of all primary cardiac tumors. A 6 month old child with coughing and obstruction in breathing, was hospitalized in the Pediatric Clinic in UCCK, Pristine. The difficulty of breathing was heard and the pathological noise of the heart was noticed from the pediatrician. In the echo of the heart at the posterior and apico-lateral part of the left ventricle a tumoral mass was presented with the dimensions of 56 × 54 mm that forwarded the contractions of the left ventricle, the mass involved also the left ventricle wall and was not vascularized. The right ventricle was deformed and with the shifting of the SIV on the right the contractility was preserved. Aorta, the left arch and AP were normal with laminar circulation. The pericard was presented free. Radiography of thoracic organs was made; it resulted on cardiomegaly and significant bronchovascular drawing. It was completed with an MRI and it resulted on: Cardiomegaly due to large tumoral mass lesion (60×34 mm) involving lateral wall of left ventricle. It was isointense to the muscle on T1W images, markedly hyperintense on T2W images. There were a few septa or bant like hypointensities within lesion. On postcontrast study it showed avid enhancement. The left ventricle volume was decreased. Mild pericardial effusion was also noted. Surgical intervention was performed and it resulted on the histopathological aspect as a huge infantile rhadbomyoma. In most cases no treatment is required and these lesions regress spontaneously. Patients with left ventricular outflow tract obstruction or refractory arrhythmias respond well to surgical excision. Rhabdomyomas are frequently diagnosed by means of fetal echocardiography during the prenatal period.

    Previous work has demonstrated best results for casting in infantile scoliosis when the curves are small and the child begins casting under 2 years of age. This study examines if casting can delay the need for growth friendly instrumentation in severe curves (50 to 106 degrees) and how the comorbidities of syrinx or genetic syndromes affected outcomes. All children undergoing casting for scoliosis at a single institution over an 8-year period were examined. Inclusion criteria included initial curve at first casting of ≥50 degrees, age ≤3 years at the start of casting, and a minimum follow-up of 3 years. Of 148 children undergoing casting during this period, 44 met our inclusion criteria. All children underwent magnetic resonance imaging. Ten children with a syrinx were identified. Ten children had known genetic syndromes (2 who also had a syrinx). The 26 children without these comorbidities were considered idiopathic. Curve magnitude ranged from 50 to 106 degrees. Nine of the 26 (35%) children in the children with idiopathic curves demonstrated resolution of their curves, while only 3 of the remaining 18 (17%) did. Of the children that did not have resolution of their curves, 14 were maintained over the entire follow-up period to within 15 degrees of their initial curve and 13 were improved 15 degrees or more. Only 5 children had an increase of 15 degrees or more over the follow-up period and 4 of these have undergone growth friendly instrumentation after a mean delay from initial cast of 71 months (range, 18 to 100 mo). This study demonstrates that even in severe curves, casting was effective in delaying instrumentation in all cases, and led to curve resolution of the curves in 12 of 44 children. Level III-case control study.

    Full Text Available FUNDAMENTO: Las parasitosis intestinales en los niños constituyen un problema de salud pública que debe ser valorado periódicamente en cada región. En este trabajo se aborda, por primera vez en la región natural del Valle del Guadalquivir, un estudio amplio sobre la prevalencia del parasitismo intestinal en la población infantil de la zona. MÉTODOS: Durante el período 1994-1996, mediante análisis coprológico y método de Graham, se ha estudiado a 1.917 niños y niñas asintomáticos, con edades comprendidas entre seis y diez años, residentes en veinte localidades del Valle del Guadalquivir. RESULTADOS: El índice global de parasitación ha sido del 27,12 %. Las especies parásitas detectadas, así como sus prevalencias fueron: Enterobius vermicularis (20,44%, Giardia lamblia (5,05%, Entamoeba coli (2,45%, Endolimax nana (1,61%, Entamoeba histolytica (0,31%, Entamoeba hartmanni (0,05%, Iodamoeba bütschlii (0,05%. CONCLUSIONES: La prevalencia global encontrada es similar a la de otras regiones españolas, aunque quizás pueda considerarse algo más favorable. No se detectan geohelmintos, debido posiblemente a la mejora de la infraestructura higiénico-sanitaria y a los efectos de la prolongada sequía en la zona. La giardiasis, a diferencia de las restantes protozoosis, mantiene una prevalencia relativamente alta.

    ABSTRACT Objective: Whole genome sequencing and the screening of 103 families recently led us to identify PRRT2 (proline-rich-transmembrane protein) as the gene causing infantile convulsions (IC) with paroxysmal kinesigenic dyskinesia (PKD) (PKD/IC syndrome, formerly ICCA). There is interfamilial and intrafamilial variability and the patients may have IC or PKD. Association of IC with hemiplegic migraine (HM) has also been reported. In order to explore the mutational and clinical spectra, we analyzed 34 additional families with either typical PKD/IC or PKD/IC with migraine. Methods: We performed Sanger sequencing of all PRRT2 coding exons and of exon-intron boundaries in the probands and in their relatives whenever appropriate. Results: Two known and 2 novel PRRT2 mutations were detected in 18 families. The p.R217Pfs*8 recurrent mutation was found in ≈50% of typical PKD/IC, and the unreported p.R145Gfs*31 in one more typical family. PRRT2 mutations were also found in PKD/IC with migraine: p.R217Pfs*8 cosegregated with PKD associated with HM in one family, and was also detected in one IC patient having migraine with aura, in related PKD/IC familial patients having migraine without aura, and in one sporadic migraineur with abnormal MRI. Previously reported p.R240X was found in one patient with PKD with migraine without aura. The novel frameshift p.S248Afs*65 was identified in a PKD/IC family member with IC and migraine with aura. Conclusions: We extend the spectrum of PRRT2 mutations and phenotypes to HM and to other types of migraine in the context of PKD/IC, and emphasize the phenotypic pleiotropy seen in patients with PRRT2 mutations.

    Full Text Available Introducción: El control prenatal se define como todas las acciones y procedimientos, sistemáticos y periódicos, destinados a la prevención, diagnostico y tratamiento de los factores que pueden coordinar la morbilidad y mortalidad materna y perinatal. La muerte de una madre es una tragedia evitable que afecta una vida joven llena de grandes esperanzas; es una de las experiencias más traumáticas que puede sufrir una familia y afecta seriamente el bienestar, la supervivencia y el desarrollo de los hijos, especialmente de los más pequeños. Todo lo anterior trae como consecuencia el debilitamiento de la estructura social en general. Materiales y Métodos: Es un estudio descriptivo de corte transversal, en el cual, se identificaron aspectos importantes como las variables sociodemográficas, clínicas, barreras de acceso y adherencia para el ingreso temprano al control prenatal de las gestantes que consultan a una unidad materno infantil. Resultados: El control prenatal representa una estrategia básica que permite identificar factores de riesgo y alteraciones fisiológicas en toda paciente gestante. Los resultados expresados en Le presente trabajo muestran el impacto favorable cuando no inciden las variables de riesgo. Discusión y Conclusiones: Queda demostrado que con un número suficiente de controles prenatales y efectuados en forma precoz, estas pacientes pueden ser contenidas en su situación y se llega a disminuir en forma muy importante la mortalidad perinatal.

    Full Text Available A brincadeira sempre esteve presente na vida da criança, contribuindo para o seu processo de desenvolvimento. Dessa forma, buscou-se o entendimento do significado, as possibilidades e controvérsias do jogo, a partir de diferentes enfoques. Utilizando-se de uma revisão bibliográfica, partiu-se de uma definição de termos como jogo, brincadeira e brinquedo, para melhor compreensão do assunto. Em seguida, analisou-se a evolução da brincadeira em diferentes fases do desenvolvimento da criança, na visão de alguns autores tais como Piaget e Vygotski, bem como o brinquedo enquanto objeto e suas qualidades, na tentativa de compreender a atividade lúdica infantil nos dias atuais, diante da subordinação à industrialização e ao avanço tecnológico. Dentre os pontos destacados, ressaltam-se os benefícios da atividade lúdica e os prejuízos de sua ausência. Deve-se proporcionar à criança momentos desta atividade e uma educação para usufruí-la nas diversas fases de sua vida, de maneira a atender suas necessidades intrínsecas. Deve-se destacar que o contato com a variedade de brinquedos estimula a ação, a representação e a imaginação da criança, ajudando-a até a superar diferentes barreiras e proporcionando o desenvolvimento da criatividade.

Pero también lo imaginario en la «literatura creada» enlaza a menudo con el folclore y, aunque no participe del carácter tradicional, popular y anónimo del mismo, responde a idénticos componentes de psiquismo profundo y a la necesidad de simbolizarlos, y posee similar estructura a los relatos del pasado. Trataremos del valor educativo de este tipo de composiciones poéticas o narrativas, sin olvidarnos del «teatro de animación», ni de su más válida manifestación en el aula: la dramatización o juegos de libre expresión dramática abierta a la imaginación y a la creatividad del niño.SUMMARY: Traces of folklore are abundant in children's literature and they acquire a living presence in what Cervera calls «earned literature» (traditional stories, rhymes and games with a literaty support. But the imaginary aspect in «creative literature » also ties in with folklore and, although it is not a part of its traditional, popular and anonymous character, it does respond to identical components of the deep psyche and the need to symbolize them, and has a structure similar to the stories of the past. Our study also deals with the educational value of folklbric narratives and verse, without overlooking «participatory drama», or its most important expression in the classroom: dramatization or games of free dramatic open to the imagination and creativity of the child.

    There are conflicting reports about the renal involvement in Behcet's disease (BD). In this study we aimed to study the frequency and type of renal involvement in a group of patients with BD in Azerbaijan province that is one of the prevalent areas of BD in Iran. All cases of BD were prospectively followed between June 2004 and January 2007, and evaluated for renal dys-function (serum creatinine > 1.7 mg/dL), glomerular hematuria and proteinuria. Those patients with proteinuria > 500 mg/day and serum creatinine level > 2 mg/dL, underwent renal biopsy. From a total number of 100 patients, six patients (6%) had obvious renal involvements. Four patients had glomerular hematuria and proteinuria. Renal biopsy in two of them revealed measangial proliferative glumerulonephritis with IgA deposit in one of them and membranoproliferative glumerolonephritis in another one. Two remaining patients had serum creatinine > 2 mg/dL without any hematuria or proteinuria. Serologic study for viral agents and collagen vascular disease were negative in all patients with renal involvements. In conclusion, renal involvement in BD is not infrequent, although in most cases it is mild in nature and may be missed. (author)

  13. Ultrasonography in chronic renal failure

    International Nuclear Information System (INIS)

    2003-01-01

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option

    Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.

  16. Fetal programming of renal function.

    2012-04-01

    Results from large epidemiological studies suggest a clear relation between low birth weight and adverse renal outcome evident as early as during childhood. Such adverse outcomes may include glomerular disease, hypertension, and renal failure and contribute to a phenomenon called fetal programming. Other factors potentially leading to an adverse renal outcome following fetal programming are maternal diabetes mellitus, smoking, salt overload, and use of glucocorticoids during pregnancy. However, clinical data on the latter are scarce. Here, we discuss potential underlying mechanisms of fetal programming, including reduced nephron number via diminished nephrogenesis and other renal (e.g., via the intrarenal renin-angiotensin-aldosterone system) and non-renal (e.g., changes in endothelial function) alterations. It appears likely that the outcomes of fetal programming may be influenced or modified postnatally, for example, by the amount of nutrients given at critical times.

    Full Text Available Primary hyperparathyroidism (PHPT is associated with nephrolithiasis and nephrocalcinosis. Hypercalciuria is one of the multiple factors that is implicated in the complex pathophysiology of stone formation. The presence of a renal stone (symptomatic or asymptomatic categorizes PHPT as symptomatic and is an indication for parathyroid adenomectomy. Progression of nephrocalcinosis is largely reversible after successful surgery, but the residual risk persists. PHPT is also associated with declining renal function. In case of asymptomatic mild PHPT, annual renal functional assessment is advised. Guidelines suggest that an estimated glomerular filtration rate (eGFR < 60 ml / minute / 1.73 m 2 is an indication for parathyroid adenomectomy. This article discusses how to monitor and manage renal stones and other related renal parameters in case of PHPT.

    BACKGROUND: This article summarizes the 2012 European Renal Association-European Dialysis and Transplant Association Registry Annual Report (available at www.era-edta-reg.org) with a specific focus on older patients (defined as ≥65 years). METHODS: Data provided by 45 national or regional renal...... disease (ESRD) receiving renal replacement therapy (RRT) and renal transplantation rates for 2012 are presented. RESULTS: In 2012, the overall unadjusted incidence rate of patients with ESRD receiving RRT was 109.6 per million population (pmp) (n = 69 035), ranging from 219.9 pmp in Portugal to 24.2 pmp...... to 32% between countries. The overall renal transplantation rate in 2012 was 28.3 pmp (n = 15 673), with the highest rate seen in the Spanish region of Catalonia. The proportion of patients ≥65 years receiving a transplant ranged from 0 to 35%. Five-year adjusted survival for all RRT patients was 59...

    Magnification selective renal arteriograms were performed on 24 patients, 12 of whom were hypertensive, and compared with non-magnification arteriograms by two observers independently. The magnification angiograms were performed on a Siemens Microfocus Bi 125/3/50 RG tube with a 0.1 mm focal spot. Of the 24 patients examined, information crucial to the diagnosis was found only on the magnification films in three patients (12.5%). Extra information compared with the non-magnification films was found in the magnification films in 12 patients (50%). No additional information was discovered in the remaining nine patients (37.5%). The magnification angiograms enabled the interlobular vessels to be visualised - this was not possible on the non-magnification films. Against the additional information gained must be weighed the disadvantages of magnification arteriography which include increased radiation dose and lengthening of procedure time plus additional injections of contrast. In conclusion, there is a place for magnification renal arteriography and the advantages seem to outweigh the disadvantages. (author)

    Peri-operative acute kidney injury is common, accounting for 30-40% of all in-hospital cases of acute kidney injury. It is associated with clinically significant morbidity and mortality even with what was hitherto regarded as relatively trivial increases in serum creatinine, and carries over a 12-fold relative risk of death following major abdominal surgery. Comorbid conditions such as diabetes, hypertension, liver disease and particularly pre-existing chronic kidney disease, as well as the type and urgency of surgery, are major risk factors for the development of postoperative acute kidney injury. As yet, there are no specific treatment options for the injured kidney, although there are several modifiable risk factors of which the anaesthetist should be aware. As well as the avoidance of potential nephrotoxins and appropriate volume balance, optimal anaesthetic management should aim to reduce the risk of postoperative renal complications. This may include careful ventilatory management and blood pressure control, as well as appropriate analgesic strategies. The choice of anaesthetic agent may also influence renal outcomes. Rather than concentrate on the classical management of acute kidney injury, this review focuses on the potential development of acute kidney injury peri-operatively, and the means by which this may be ameliorated. © 2018 The Association of Anaesthetists of Great Britain and Ireland.
