Full Text Available Epidermal nevus syndrome (ENS is a rare disease, the pathogenesis of which is largely elusive. We, hereby, report an exclusive case of a 20-year-old man with verrucous ENS presented with dark colored papules and plaques along the Blaschko′s lines present over the head and neck area along with fleshy growth in both eyes since birth. Limb length discrepancy and kyphoscoliosis were remarkable. Skin biopsy was compatible with verrucous epidermal nevus while the biopsy of the ocular lesion confirmed complex choristoma. MRI brain revealed calcification in the right temporal lobe. Bilateral arachnoid cyst in the middle cranial fossa, scleral osteoma in the posterior part of the right eyeball, and deformed calvarium were evident on CECT skull and orbit. The present illustration emphasizes the importance of a punctilious work up of the case.

Full Text Available O nevo de Becker se manifesta como uma mácula hipercrômica, localizada predominantemente no tronco anterior ou região escapular, e frequentemente associada à hipertricose. A coexistência do nevo de Becker e anormalidades cutâneas, músculo-esqueléticas ou maxilo-faciais corresponde à síndrome do nevo de Becker. Relata-se o caso de uma paciente de 16 anos, portadora desde os sete anos de mácula hipercrômica, localizada no tronco ântero-lateral direito, estendendo-se até a face medial da coxa direita, acompanhada de hipoplasia mamária ipsilateral. O exame anatomopatológico confirmou a hipótese clínica de nevo de Becker.Becker's nevus is a hyperpigmented macula that is predominantly located on the anterior trunk or on the scapular region, frequently associated with hypertrichosis. The association of Becker's nevus with other cutaneous, musculoskeletal or maxillofacial anomalies has been called Becker's nevus syndrome. We report a case of a 16-year-old girl with a hyperpigmented macula which spread from her right anterolateral trunk to the inner part of her right thigh accompanied by ipsilateral mammary hypoplasia. The skin lesion started when the patient was seven years old when it was also noticed ipsilateral mammary hypoplasia. The histological exam confirmed the clinical hypothesis of Becker's nevus.

Fatal Metastatic Cutaneous Squamous Cell Carcinoma Evolving from a Localized Verrucous Epidermal Nevus

Hassan Riad

2013-10-01

Full Text Available A malignant transformation is known to occur in many nevi such as a sebaceous nevus or a basal cell nevus, but a verrucous epidermal nevus has only rarely been associated with neoplastic changes. Keratoacanthoma, multifocal papillary apocrine adenoma, multiple malignant eccrine poroma, basal cell carcinoma and cutaneous squamous cell carcinoma (CSCC have all been reported to develop from a verrucous epidermal nevus. CSCC has also been reported to arise from other nevoid lesions like a nevus comedonicus, porokeratosis, a sebaceous nevus, an oral sponge nevus and an ichthyosiform nevus with CHILD syndrome. Here we report a case of progressive poorly differentiated CSCC arising from a localized verrucous epidermal nevus, which caused both spinal cord and brain metastasis.

Severe Blue Rubber Bleb Nevus Syndrome in a Neonate

DEFF Research Database (Denmark)

Hansen, L; Wewer, V; Pedersen, S

2008-01-01

We report on a child with blue rubber bleb nevus syndrome (BRBNS) presenting during the first days of life with severe bleeding from the upper gastrointestinal tract. Medical treatment with methylprednisolone, cyklokapron, interferon 1 alpha and numerous blood transfusions were given to control...... problems. The case is unique because 1) it is the first neonatal case with BRBNS and severe gastrointestinal bleeding; 2) the patient was successfully treated by endoscopic electrocoagulation; and 3) the long-term follow-up. The use of electrocoagulation appears to have been effective and ablation...... bleeding during the first 3 years of life. Afterwards repeated endoscopic electrocoagulations were performed over a period of one year resulting in a termination of bleeding episodes. At ten years of age the patient developed spastic diplegia with slight walking disabilities, coordination and fine motor...

Jejunal intussusception in a Chinese 10-year-old boy affected by the blue rubber bleb nevus syndrome is presented and discussed. The syndrome is rare, sporadically found with possible dominant inheritance, and due to a gene mutation mapped on the short arm of chromosome 9. It presents with distinctive cutaneous and gastrointestinal malformations together with possible other organ involvement. Gastrointestinal malformations tend to bleed and lead to anaemia. Infrequent complications of the gastrointestinal malformations are volvulus, intestinal infarction and intussusception. The age of the patient and the jejunal intussusception precipitated by a vascular malformation containing calcifications (which were also found in different gut segments) make this case remarkable.

To our knowledge this is the first report of ENS with lymphoedema occurring together in the same individual. (orig.)

Extensive nevus comedonicus, complicated with recurrent abscesses, successfully treated with surgical resurfacing

Directory of Open Access Journals (Sweden)

Narender Manikavachakan

2018-01-01

Full Text Available Nevus comedonicus is a rare epidermal abnormality of the pilosebaceous unit, which is congenital in most patients but may also appear early in childhood. It may be localized or have an extensive involvement, the latter showing a unilateral predominance with only a few cases presenting bilaterally. Extensive nevus comedonicus can be associated with musculoskeletal defects, eye and neurological involvement, which constitutes nevus comedonicus syndrome. Uncomplicated nevus comedonicus can be treated with topical keratolytics, diode, erbium laser, and ultrapulse CO2 laser. Surgical excision can be performed to ensure complete removal and nonrecurrence. This case report refers to a young male patient with extensive nevus comedonicus present over left chest, left axilla, and left upper back without systemic involvement, treated with staged surgical excision and resurfacing.

Jiang, Shan; Chen, Yan; Hinchliffe, Taylor E; Wu, Tianfu; Stephen, Tyring

2018-03-01

Kissing nevus is a very rare congenital melanocytic nevus. Here, we describe one case of kissing nevus on the penis. A 15-year boy presented with asymptomatic black to dark brown color patches on his penis. Histopathological findings showed that there were nests and cords of nevus cells in upper dermis. No significant cytologic atypia and mitoses were noted. Immunohistochemical stains revealed a partial positive for HMB-45 only in upper dermis and a stronger positivity for S-100 in almost all nevus cells. We diagnosed the lesion as kissing nevus of penis. The patient and his parents refused further treatment, and the patient is being followed in our clinic.

A case of linear nevus sebaceous syndrome showing abnormalities by head CT scan

International Nuclear Information System (INIS)

Matsuda, Yoshio; Kuraya, Kazue; Sumiyoshi, Minoru; Seki, Shuichiro; Murakami, Naoki

1982-01-01

A female baby weighing 2,702 g, who was delivered spontaneously after 37 weeks of gestation, showed linear nevus sebaceous syndrome with abnormalities on EEG and head CT scan. Immediately after birth, the baby showed abnormalities of the skin in the left half of the body, especially from the head to the face. At the same time, EEG showed a low voltage on the affected side, and head CT scan showed expansion of the lateral ventricle. Funduscopic findings showed retinochoroidal toxoplasmosis-like degeneration. This disease has been rarely reported. An early diagnosis is seemed to be important since the skin lesion per se was premalignant, and generalized abnormalities including those of the central nervous system occurred concurrently.

Joubert syndrome presenting as unilateral dysplastic kidney, hypotonia, and respiratory problem

Directory of Open Access Journals (Sweden)

Majid Malaki

2012-01-01

Full Text Available An 8-month-old girl with a history of asphyxia and respiratory distress immediately after birth was hospitalized at her fourth month of age with the diagnosis of kidney infection and it was revealed that she had a unilateral multicystic dysplastic kidney. In recent admission, she presented to emergency room with fever, hyperpnea, and apnea. In appearance, she was a hypotonic girl with broad forehead, hypertelorism, depressed nasal bridge and bitemporal regions, rapid vertical and horizontal nystagmus, and open mouth with salivation. In spite of normal physical growth, she had delayed developmental milestones. Blood gas O 2 saturation dropped after she received phenobarbital. Her urinary and blood tests were normal; however, her cranial magnetic resonance imaging (MRI revealed vermis agenesis and molar tooth sign. These physical and para-clinical findings suggested Joubert syndrome.

Recurrent nevus (RN) is a cutaneous benign tumour with similarities with malignant lesions. Typically, it occurs after a partial resection of commun-acquired nevus. Its incidence varies from 0.3 to 27% according to the studies. We present here a pediatric case of a pagetoid form of a recurrent nevus occurring from a congenital nevus. A congenital nevus was removed from a 9-month-old girl. Pathologists concluded to a commun-acquired nevus of complete exeresis. Two other cutaneous lesions appeared and we decided to realise a total removal. Analysis showed a recurrent nevus with some atypical histological features. No recurrence has occurred during the three post-operative of follow-up. It is an interesting case because of the occurrence of a RN after the removal of a congenital nevus in a child. Furthermore, it displayed some atypical histological features. Practicians, such as surgeons, dermatologists or pathologists, have to be aware of the risk of misdiagnosis with this lesion, which presents some similarities with SSM melanoma. It would be interesting to determinate some markers to statuate about its benign feature. There is no management recommendation about this lesion but it seems to be necessary to remove it to eliminate a malignant tumour. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Wiesner Nevus of the Eyelid.

Science.gov (United States)

Somogyi, Marie; Lyons, Lance J; Durairaj, Vikram

A healthy 31-year-old female presented with an elevated vascular lesion on the right lower eyelid margin. Histology results from excisional biopsy demonstrated a range of intradermally nested atypical melanocytes with negative staining for BRCA1-associated protein 1, confirming the diagnosis of Wiesner nevus. Wiesner nevi may be a cutaneous hallmark of the BRCA1-associated protein 1-associated cancer susceptibility syndrome, and to our knowledge, this is the first report of such a lesion presenting anywhere on the ocular adnexa.

Ashwin Kodliwadmath

2017-08-01

Full Text Available Context: Dysplastic pulmonary valve stenosis is a less common variety of valvular pulmonary stenosis. It is known to be part of Noonan syndrome. Bony hand anomalies in patients of pulmonary stenosis are very rare. Case report: A 50-year-old lady, with no significant past history, presented with slowly progressive breathlessness and fatigue, and had progressed from NYHA class 1 to 2 over 2 years. She had unilateral absent first metacarpal and diagnosed on workup to have dysplastic pulmonary valve stenosis and was treated with balloon valvuloplasty. Conclusion: Dysplastic pulmonary valve stenosis can rarely be associated with bony hand anomalies like absent first metacarpal.

Meningeal Melanomas Associated With Transforming Ota Nevus to Malignant Melanoma: A Case Report

Directory of Open Access Journals (Sweden)

Seyed-Mohammad Fereshtehnejad

2010-11-01

Full Text Available Intracranial invasion of cellular blue nevus (CBN from the skin is extremely rare and such a condition with malignant transformation is even rarer.A case of meningeal melanoma with malignant transformation which was derived from an Ota   nevus is presented in this report.   A21-year-old man with a neurocutaneous syndrome since childhood was referred with headache and mild left hemiparesia. CT scan and MRI demonstrated intracranial lesions and conjunctival biopsy leads to the pathologic diagnosis of blue nevus.Thereafter his parietal lesion was operated by craniotomy with total gross excision.On histopathological examination, diagnosis of malignant melanoma was confirmed.Approximately 2 months after radiotherapy and chemotherapy, he afflicted to diplopia and blurred vision on the leftside due to enlargement of orbital and cavernous sinus lesion. Following one year follow-up,he was survived and thrived with diffuse leptomeningeal nodular enhancement in favor of melanoma dissemination.Primary intracranial melanomas are though rare, but it should be suspected especially in the presence of periorbital blue nevus or nevus of Ota. Moreover, although CBN is considered benign, scalp or periorbital CBN has the potential for intracranial invasion and malignant ransformation.

Significance of adrenergic receptors for the development of nevus flammeus and nevus anemicus

Energy Technology Data Exchange (ETDEWEB)

Raff, M [Vienna Univ. (Austria). 2. Hautklinik

1981-01-01

Examination of patients with nevus flammeus or nevus anemicus showed disturbed sensibility in the area of the nevus in the majority of cases. Histologically and with special technique of histochemistry and fluorescence microscopy there was no evidence for neurogenic lesions. However, signs of vegetative disfunction were present: hyperhidrosis and absent reactivity of vasculature in the nevus area to vasoconstrictive and vasodilatatory stimuli. Based on these findings a disturbed regulation of vascular intramural adrenergic receptors seemed possible and really could be demonstrated by means of autoradiography. In both types of nevi only one of the adrenergic receptors could be marked with specific antagonists. Therefore, the persistent vascular dilatation and constriction can be accounted for by the absence of one of these receptors. This abnormal distribution of receptors could be due to a developmental defect influenced by the ''nerve growth factor''.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by multiple venous malformations. The gastrointestinal bleeding and secondary iron deficiency anemia are the most common complications. There are currently no effective treatments for BRBNS. Here, we report a case of successful treatment with a small dose of sirolimus of a BRBN patient with a de novo gene mutation. A 12-year-old female was admitted to our hospital with multiple hemangiomas for 12 years. The patient often displayed melena; she recently received transfusion of 2 units of red blood cells once every 2 weeks. Multiple fist-sized hemangiomas were piled up on both sides and back of the neck, and were also noted on the arms, legs, chest, back, and on the tip of the tongue. The laboratory findings demonstrated severe anemia. Blood sample sequencing detected a heterozygous de novo mutation c.2545C > Tin the TEK gene. Based on these findings, final diagnosis of Blue rubber bleb nevus syndrome (BRBNS) was made. After the diagnosis, low-dose sirolimus was orally administered. The patient's hemoglobin was increased after treatment with sirolimus for 1 month. Since the initial treatment with sirolimus, she had not received any blood transfusions. The skin and mucosal hemangioma decreased significantly, and new digestive tract hemorrhage, muscle hematoma, or adverse drug reactions were not observed. we report a case of a mutation in exon 15 of the TEK gene leading to BRBN. It was successfully treated with a small dose of sirolimus as an alternative to blood transfusion in order to save the of BRBN patient's life.

An amelanotic, circum-corneal nevus in a 2-year-old child is described. The nevus presented at birth as a red spot in the nasal conjunctiva that subsequently enlarged to completely encircle the cornea. The tumour was partially removed three times, but at the age of 6 years, the nevus still covers...... the entire limbal region. The case illustrates that circum-corneal redness in a child may be caused by a nevus and that a conjunctival limbal nevus in a child tend to recur after incomplete excision....

Cerebriform intradermal nevus presenting as cutis verticis gyrata with multiple cellular blue nevus over the body: A rare occurrence

Directory of Open Access Journals (Sweden)

Somenath Sarkar

2014-01-01

Full Text Available Cutis verticis gyrata is a rare skin condition characterized by swelling of scalp resembling the surface of the brain. Various conditions, like cerebriform intradermal nevus (CIN, may give rise to this clinical entity. Moreover, its association with cellular blue nevus is extremely rare and has not been reported so far. Here, we report a 28-year-old male with a huge cerebriform swelling covering the occipital lobe along with multiple nodules all over the body. Histology of the scalp swelling showed solitary or clusters of nevus cells in the dermis and from the body lesions showed features of cellular blue nevus. The diagnosis of CIN with cellular blue nevus was confirmed

Morcos, Mohib W; Odashiro, Alexandre; Bazin, Richard; Pereira, Patricia Rusa; O'Meara, Aisling; Burnier, Miguel N

2014-12-01

Balloon cell nevus is a rare histopathological lesion characterized by a predominance of large, vesicular and clear cells, called balloon cells. There is only 1 case of balloon cell nevus of the iris reported in the literature. A 55 year-old man presented a pigmented elevated lesion in the right iris since the age of 12 years old. The lesion had been growing for the past 2 years and excision was performed. Histopathological examination showed a balloon cell nevus composed of clear and vacuolated cells without atypia. A typical spindle cell nevus of the iris was also observed. The differential diagnosis included xanthomatous lesions, brown adipocyte or other adipocytic lesions, clear cell hidradenoma, metastatic clear cell carcinoma of the kidney and clear cell sarcoma. The tumor was positive for Melan A, S100 protein and HMB45. Balloon cell nevus of the iris is rare but should be considered in the differential diagnosis of melanocytic lesions of the iris.

Congenital Becker's nevus with a familial association.

Science.gov (United States)

Book, S E; Glass, A T; Laude, T A

1997-01-01

Becker's nevus is a unilateral, hyperpigmented cutaneous hamartoma usually with hypertrichosis. It occurs predominantly in boys, becoming apparent during adolescence, although several cases of congenital Becker's nevus have been reported. Rarely it may be familial and as such is transmitted in an autosomal dominant pattern. We report a 16-month-old black boy with a hyperpigmented patch on his right shoulder and upper pectoral area that extended down his arm. The patient's father has a similar lesion with hair on his left shoulder which has been present since childhood. Histology of the child's lesion was consistent with Becker's nevus. We believe this to be the first reported case of a congenital Becker's nevus with a familial association.

A Rare Case of Multifocal Prostatic Blue Nevus

Directory of Open Access Journals (Sweden)

Elias J. Farran

2018-01-01

Full Text Available Prostatic blue nevus is a rare benign pathologic diagnosis most commonly diagnosed incidentally on many different types of prostate specimens. Blue nevus is the deposition of stromal melanin characterized by spindle cells within the fibromuscular stroma which stains positive for melanin-specific stains Fontana-Masson and S100 and stains negative for CD68, HMB45, and iron stains. We report the case of a multifocal and bilateral blue nevus in a 52-year-old Hispanic male who presented with an elevated prostate-specific antigen of 4.3 and mild obstructive lower urinary tract symptoms, found by transrectal ultrasound-guided prostate needle biopsy. The biopsy also revealed benign prostatic tissue with postatrophic hyperplasia and chronic inflammation. This is the 35th reported case of prostatic blue nevus and the third to show multifocal blue nevus.

Conclusions: Nevus with histopathologically confirmed nevomelanocytic atypia (dysplastic nevus could not be distinguished from nevus without atypia using analyzed in vivo RCM features of melanocytic atypia. More accurate diagnostics by means of in vivo RCM needs further investigation on reflectance of single and nested cutaneous melanocytes in benign and malignant skin lesions.

Intraoral blue (Jadassohn-Tieche) nevus.

Science.gov (United States)

Hasse, C D; Zoutendam, G L; Gombas, O F

1978-05-01

Blue nevus of the oral mucosa is a distinctly uncommon clincial entity. Careful review of the literature yielded thirty-one previously reported cases. The present article reports the occurrence of a blue nevus of the hard palate in a 58-year-old man. It is of interest since it is the smallest (1 by 1 mm.) intraoral blue nevus to be reported. A clinicopathologic study of the previous thirty-one cases and of our case suggests that this lesion has no age or sex predilection. The most common site of occurrence was the hard palate. There appears to be no tendency toward recurrence. A brief review of the historical background, clinical features, theories of possible origin, and differential diagnosis is presented. Excisional biopsy of localized areas of oral pibmentation, together with histopathologic study, is indicated to rule out melanoma.

Autofluorescence of choroidal nevus in 64 cases.

Science.gov (United States)

Shields, Carol L; Pirondini, Cesare; Bianciotto, Carlos; Materin, Miguel A; Harmon, Sarah A; Shields, Jerry A

2008-10-01

To describe the autofluorescence features of choroidal nevi. Noncomparative case series. Sixty-four consecutive patients. Correlation of fundus photography with autofluorescence photography. Autofluorescence features of choroidal nevus and overlying retinal pigment epithelium (RPE). The mean patient age was 62 years. The choroidal nevus was a mean of 5 mm from the optic disk and foveola. The mean tumor basal dimension was 5.0 mm and mean tumor thickness was 1.0 mm. The choroidal nevus showed hypoautofluorescence in 56%, isoautofluorescence in 19%, and hyperautofluorescence in 25%. The autofluorescence features appeared unaffected by tumor thickness, but increasing tumor base and disrupted overlying RPE appeared to produce slightly brighter autofluorescence. Nevi located in the macular region showed darker hypoautofluorescence than those outside the macular region. Overlying RPE hyperplasia, atrophy, and fibrous metaplasia were generally hypoautofluorescent. Drusen, subretinal fluid, and orange pigment were generally hyperautofluorescent. The brightest hyperautofluorescence was found with orange pigment. Choroidal nevus shows little intrinsic autofluorescence. Overlying RPE alterations show dramatic autofluorescence ranging from dark hypoautofluorescence of RPE atrophy to bright hyperautofluorescence of orange pigment.

Four Different Tumors Arising in a Nevus Sebaceous

Directory of Open Access Journals (Sweden)

Takeshi Namiki

2016-04-01

Full Text Available Nevus sebaceous is known by its association with one or more secondary tumors, but more than three multiple tumors arising from a nevus sebaceous is extremely rare. A 67-year-old female presented with a light brown plaque on the back of her head that contained a dome-shaped black node and an erosive lesion. Histopathological examination showed atypical basaloid cells in the black node. At the periphery of that node, structures resembling follicular germs extruded from interlacing cords in the upper portion and tumor nests with sebocytes were in the lower portion. In the erosive lesion, papillated structures with an apocrine epithelium were observed. In the light brown plaque, enlargement of sebaceous lobules was noted. From those histopathological features, a diagnosis of syringocystadenoma papilliferum, sebaceoma, trichoblastoma and basal cell carcinoma arising from a nevus sebaceous was made. We discuss the rarity of multiple tumors arising from a nevus sebaceous.

Antenatal diagnosis of multicystic dysplastic kidney was made in 34 (72.3%) patients. On follow up of 31 children for more than 12 months, 21 (68%) had involution, 4 [13%] had non-regression, and 4 (13%) were nephrectomized. Vesico-ureteric reflux (n=13; 28%) was the commonest renal abnormality. The serum creatinine values were higher (P=0.006) in children with contralateral reflux. Sub-nephrotic proteinuria was noted in 9 (29%) and was significantly associated with complete involution (P=<0.023). None of the patients developed hypertension and 2 (6.4%) had renal failure. Close nephrological follow-up is needed in children with multicystic dysplasia of kidneys.

Full Text Available An 81-year-old Japanese man presented with dark blue papules and nodules on his face. There were multiple soft papules and nodules, dark blue in color, compressive, and ranging in size from 2 to 10 mm. A few similar lesions were seen on the patient's right dorsal second toe and right buccal mucosa. There were no skin lesions on his trunk and upper limbs. The patient's past history did not include gastrointestinal bleeding or anemia. Histopathological examination showed dilated vascular spaces lined by the normal epithelium extending beneath the dermis and into the subcutaneous fat. Endoscopy of the gastrointestinal tract to check for colon involvement was not performed. X-ray images of the limbs revealed no abnormalities in the bones or joints. Laboratory investigations did not show anemia. Although we failed to confirm a diagnosis by endoscopy, the skin lesions, histopathological findings, lack of abnormal X-ray findings, and the presence of oral lesions as a part of gastrointestinal tract guided the diagnosis of blue rubber bleb nevus syndrome (BRBNS. Skin lesions of BRBNS occur predominantly on the trunk and upper limbs. However, the present case showed multiple skin lesions predominantly on the face. Therefore, it is important for clinicians to know about a possible atypical distribution of skin lesions in BRBNS.

Full Text Available Congenital melanocytic nevi (CMN are visible hyperpigmented (melanocytic, benign, tumor like proliferations in the skin resulting from faulty development of pigment cell precursors in the embryo, and are composed of an abnormal mixture of skin elements. Giant congenital melanocytic nevus (GCMN is usually defined as a melanocytic lesion present at birth that will reach a larger size in adulthood. GCMN is a rare variety of CMN which is characterized by its size (diameter ≥20 cm and the potential for malignant transformation. It is infrequently associated with other findings, which makes the clinical picture complex. In this case, we report a rare association of GCMN with intraoral blue nevus in a 24-year-old male patient.

Full Text Available El nevus blanco esponjoso (NBE es una rara condición autosómica dominante, caracterizada por placas blancas bilaterales en la mucosa, de aspecto esponjoso, blandas a la palpación y que pueden escamarse. Los tratamientos son paliativos; y el uso de antibióticos, en especial la tetraciclina, ha demostrando buenos resultados en su control. Este trabajo presenta tres casos clínicos de una familia afectada por NBE, donde se discuten los posibles diagnósticos diferenciales y conductas terapéuticas indicadas. Un paciente masculino de 52 años de edad acudió a la clínica aquejado de lesiones blancas bilaterales. El paciente notó las lesiones 30 años antes, sin lograr un diagnóstico final de las mismas. Después de la anamnesis y del examen clínico fue realizada una biopsia incisional. La reunión de los datos clínicos e histopatológicos llevó al diagnóstico de NBE. Se le solicitó al paciente que indagase entre sus familiares con respecto a lesiones semejantes. Se detectó que el hijo de 19 años y la hija de 25 eran portadores de placas blancas en la mucosa yugal. Como no había afectación estética, se optó por no intervenir en las lesiones. El nevus blanco esponjoso es una lesión genética que debe ser diferenciada de otras patologías localizadas y sistémicas importantes, que tienen repercusiones serias para el individuo. Como no hay un tratamiento curativo para el NBE, el papel del cirujano dentista es diagnosticar esta lesión, aclarar al paciente sobre la naturaleza benigna y autolimitante del NBE y si fuera necesario desde el punto de vista estético, aplicar diferentes modalidades terapéuticas.The aim of present paper is to introduce three clinical cases from a family affected from nevus spongiosus albus (NSA and also to discuss the possible differential diagnoses as well as the therapeutical behaviors to be adopted.

Vitiligo and halo nevus are two common T-cell-mediated skin disorders. Although autoimmunity has been suggested to be involved in both diseases, the relationship between vitiligo and halo nevus is not fully understood. The aim of the current study was to investigate whether vitiligo and halo nevus share the same immunological and oxidative stress response. Infiltrations of T cells, and expressions of chemokine receptors (CXCR3, CCR4, CCR5) and cytotoxic markers (Granzyme B, Perforin) in the lesions of vitiligo and halo nevus were examined by immunohistochemistry. Enzyme-linked immunosorbent assay was performed to analyze the expressions of chemokines in the serum samples and cytotoxic markers secreted by CD8 + T cells which were sorted from the peripheral blood mononuclear cells in healthy donors, vitiligo and halo nevus patients. Tissue levels of chemokine receptors and CXCR3 ligands in healthy controls, vitiligo patients and halo nevus patients were determined by qRT-PCR analysis. The percentages of CXCR3 + CD4 + T and CXCR3 + CD8 + T cells from the peripheral blood samples were examined by flow cytometry. Tissue and serum hydrogen peroxide (H 2 O 2 ) concentrations were measured using H 2 O 2 assay kit. Immunohistochemistry revealed a significant T-cell response, with pronounced dermal infiltrates of CD8 + T cells in vitiligo and halo nevus. The inflammatory cytotoxic markers such as Granzyme B and Perforin were also elevated in vitiligo and halo nevus, suggesting inflammatory responses in situ. By qRT-PCR and ELISA assay, we found significantly increased expressions of the chemokine receptor CXCR3 and its ligands, especially the accumulated CXCL10 in the skin lesions of vitiligo and halo nevus. Moreover, the level of H 2 O 2 , a key player involved in regulation of the immune response was significantly upregulated in the skin lesions of vitiligo and halo nevus. In addition, the increased H 2 O 2 concentration correlated positively with CXCL10 level in skin

Full Text Available Raised palmar or plantar nevus especially in white people is an unusual feature. We present an uncommon palmar compound nevus in a 26-year-old woman with a large diameter (6 mm which had a collaret-shaped margin. In histopathologic evaluation intralymphatic protrusions of nevic nests were noted. This case was surprising to us for these reasons: size, shape, location and histopathology of the lesion. Palmar nevi are usually junctional (flat and below 3 mm diameter and intra lymphatic protrusion or invasion in nevi is an extremely rare phenomenon.

Gaurav Sharma

2011-01-01

Full Text Available Nevus of Ota, a dermal melanocytic nevus, is rare in the Indian subcontinent. It presents as a brown, blue, or gray patch on the face and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The oral cavity is infrequently involved in nevus of Ota. Only 11 cases have been documented in the English literature. We report a rare case of intraoral nevus of Ota in a 22-year-old male patient. This paper focuses on the differential diagnosis of oral manifestations of nevus of Ota to assist in proper followup to avert malignant transformation.

To characterize the ultrasonographic findings of multicystic dysplastic kidney on prenatal ultrasonography (US) with a special emphasis on the distribution of cysts. From January 1998 to March 2003, medical records of sixty two subjects with multicystic dysplastic kidney diagnosed on prenatal US examination were retrospectively reviewed, and forty three patients confirmed either by pathology or postnatal follow-up US were selected for this study. US assessment included the time of diagnosis, laterality, size of the multicystic dysplastic and contralateral normal kidneys, distribution of cysts and associated anomalies. The distribution of cysts was categorized as subcapsular and random distribution, and interobserver agreement was determined using the cross table analysis. The largest multicystic and contralateral normal longitudinal diameters were measured, and the data were plotted on the normal reference chart. Multicystic dysplastic kidney was left sided in 55.8%, right sided in 34.8% and bilateral in 9.3%. Subcapsular distribution of cysts was observed in 68.2% (n=15) for radiologist 1 while 59.1% (n=13) for radiologist 2, showing an excellent interobserver agreement (k=0.697). The longitudinal diameter of the multicystic dysplastic kidney was above 95 percentile in 68%. Meanwhile, the diameter of the contralateral normal kidney was more commonly normal, 70%. Fetal karyotyping was done in 18 cases including 2 cases with associated major anomalies, but karyotyping was all normal. On prenatal US, subcapsular distribution of cysts in multicystic dysplastic kidney is more common than random distribution. This characteristic distribution of cysts may be helpful in the prenatal diagnosis of multicystic dysplastic kidney.

Hastrup, N; Clemmensen, O J; Spaun, E; Søndergaard, K

1994-06-01

Forty melanocytic lesions were examined in a pilot study, which was followed by a final series of 100 consecutive melanocytic lesions, in order to evaluate the inter-observer reproducibility of the histological criteria proposed for the dysplastic naevus. The specimens were examined in a blind fashion by four observers. Analysis by kappa statistics showed poor reproducibility of nuclear features, while reproducibility of architectural features was acceptable, improving in the final series. Consequently, we cannot apply the combined criteria of cytological and architectural features with any confidence in the diagnosis of dysplastic naevus, and, until further studies have documented that architectural criteria alone will suffice in the diagnosis of dysplastic naevus, we, as pathologists, shall avoid this term.

Full Text Available Congenital melanocytic nevus (CMN may rarely regress which may also be associated with a halo or vitiligo. We describe a 10-year-old girl who presented with CMN on the left leg since birth, which recently started to regress spontaneously with associated depigmentation in the lesion and at a distant site. Dermoscopy performed at different sites of the regressing lesion demonstrated loss of epidermal pigments first followed by loss of dermal pigments. Histopathology and Masson-Fontana stain demonstrated lymphocytic infiltration and loss of pigment production in the regressing area. Immunohistochemistry staining (S100 and HMB-45, however, showed that nevus cells were present in the regressing areas.

The first reported case of facial paralysis due to an inflammatory pseudotumor (IPT) of the facial nerve as a complication of epidermal nevus syndrome (ENS) is herein presented. A 10-month-old female patient was diagnosed with ENS at 3 months of age. She was referred to us because of moderate left facial paralysis. Epidermal nevi of her left auricle extended deep into the external ear canal. Otoscopy revealed polypous nevi and cholesteatoma debris filling the left ear. Computed tomography showed a soft mass filling the ear canal, including the middle ear, and an enormously enlarged facial nerve. Surgical exploration revealed numerous polypous nevi, external ear cholesteatoma, and tumorous swelling of the facial nerve. The middle ear ossicles were completely lost. The facial paralysis was improved after decompression surgery, but recurred 5 months later. A second operation was conducted 10 months after the first. During this operation, facial nerve decompression was completed from the geniculate ganglion to near the stylomastoid foramen. Histological diagnosis of the facial nerve tumor was IPT probably caused by chronic external ear inflammation induced by epidermal nevi. The facial paralysis gradually improved to House-Blackmann grade III 5 years after the second operation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Blue nevus is an uncommon pigmented tumor of dermal melanocytes that has traditionally been classified into common and cellular variant. It is usually a skin tumor in adults but can become apparent in early childhood or even be present at birth. Malignant blue nevus is a rare melanocytic tumor of the skin arising from a preexisting cellular blue nevus. We report a multinodular blue nevus of the left ear in an 11-year-old girl who also had 2 intracranial melanocytic lesions. Differential diagnosis between metastases from malignant blue nevus and neurocutaneous melanosis is discussed.

Verrucous Spitz Nevus in a Japanese Female

2013-11-01

Full Text Available A 23-year-old female presented with a reddish-brown dome-shaped hyperkeratotic nodule of 11 × 10 mm on the left lower leg. Dermoscopic examination demonstrated a prominent whitish scaly area with ring-like appearance, pinkish-white structureless areas, a few milia-like cysts, dotted and glomerular vessels, and light brown globules. The lesion was completely excised under the diagnosis of verruca vulgaris or dermatofibroma. Histopathological examination revealed a well-circumscribed symmetric lesion with hyperkeratosis, acanthosis, and pseudohorn cysts. The lesion was composed of spindle-shaped and epithelioid melanocytes with large cytoplasm arranged in confluent nests surrounded by stromal fibrosis. Mitotic figures and Kamino bodies were absent. Moderate proliferation of capillaries was found in the papillary dermis. Immunohistochemical staining with melan-A or S-100 was positive for tumor cells, but the staining with HMB-45 was negative. Melan-A staining was weaker in the deeply situated cells than in the superficial ones, which is known as stratification. Finally, we made a diagnosis of verrucous Spitz nevus based on these findings. We should have been aware of the entity of verrucous Spitz nevus as a variant of Spitz nevus and its dermoscopic features in order to reach a correct diagnosis before excision.

The origin of the bleeding was a giant congenital cellular blue nevus (CBN of the scalp. The report illustrates the crucial role of immediate and aggressive volume resuscitation, suturing of the skin dehiscence, and firm external compression. This therapy was combined with whole-body hypothermia. The neurological outcome of the patient was normal. A shiny blue mass on the scalp should alert neonatologists to the possibility of a blue nevus of the scalp, rather than a simple scalp hematoma. Final diagnosis is made by biopsy and histologic examination. Early surgical intervention is necessary to prevent malignant degeneration and metastasis. A multidisciplinary approach involving a pediatrician/neonatologist, dermatologist, and surgeon is thus needed for diagnosis, treatment, and long-term follow-up.Keywords: neonate, cellular blue nevus, giant blue nevus, giant congenital blue nevus, hemorrhagic shock, whole-body hypothermia

The management of dysplastic naevi is a controversial subject. This study sought to assess the usefulness of the shave biopsy technique in the initial management of dysplastic naevi, and to demonstrate the advantages over the punch biopsy technique. We report a retrospective observational study of histopathology specimens examined in one histopathology practice over a 14-month period. Patients who had a clinical diagnosis of 'dysplastic naevus', which had initially been biopsied using either a shave or punch biopsy, and then followed up with a full-thickness elliptical excision, were included in the study. Histopathological concordance between the shave and punch biopsy specimens and their respective follow-up elliptical excisions was compared. We found that 21 of 22 (95.5%) shave biopsies were concordant with their respective excision specimens, and that 29 of 41 (70.7%) punch biopsies were concordant with their respective elliptical excision specimens. Of the shave biopsy specimens reviewed, 66% showed that the dysplastic naevi were completely excised with the initial biopsy, compared with 21.2% of the punch biopsy specimens. These findings confirm that shave biopsies provide accurate diagnostic information in the assessment of dysplastic naevi. Shave biopsies enable the entire lesion to be submitted for histopathological assessment, improving the chances of an accurate diagnosis.

To explore the genetic etiology of fetuses with multicystic dysplastic kidney (MCDK) by chromosome microarray analysis (CMA). Seventy-two fetuses with MCDK were analyzed with conventional cytogenetic technique, among which 30 fetuses with a normal karyotype were subjected to CMA analysis with Affymetrix CytoScan HD arrays by following the manufacturer's protocol. The data was analyzed with ChAS software. Conventional cytogenetic technique has revealed three fetuses (4.2%) with identifiable chromosomal aberrations. CMA analysis has detected pathogenic CNVs in 5 fetuses (16.7%), which included two well-known microdeletion or microduplication syndromes, i.e., 17q12 microdeletion syndrome and Williams-Beuren syndrome (WBS) and three submicroscopic imbalances at 4q35.2, 22q13.33, and 1p33. PEX26, FKBP6, TUBGCP6, ALG12, and CYP4A11 are likely the causative genes. CMA can identify the submicroscopic imbalances unidentifiable by conventional cytogenetic technique, and therefore has a significant role in prenatal diagnosis and genetic counseling. The detection rate of pathogenic CNVs in fetuses with MCDK was 16.7% by CMA. 17q12 microdeletion syndrome and WBS are associated with MCDK. Mutations of PEX26, FKBP6, TUBGCP6, ALG12, and CYP4A11 genes may be the causes for MCDK.

Connective tissue nevi are benign hamartomatous lesions in which one or several of the components of the dermis (collagen, elastin, glicosaminoglycans) show predominance or depletion. Recently, de Feraudy et al broadened the spectrum of connective tissue nevus, describing fibroblastic connective tissue nevus (FCTN), which is characterized by proliferation of CD34(+) cells of fibroblastic and myofibroblastic lineage. Only solitary papules and nodules have been described. We present the first case of FCTN with multiple agminated lesions on the leg of an infant and the difficulties encountered in the differential diagnosis with dermatofibrosarcoma protuberans. © 2016 Wiley Periodicals, Inc.

There is an increasing demand for a limited number of pigmented lesion clinic (PLC) visits at dermatology centers. To determine the proportion of visits to PLCs that are more frequent ("additional screening") than the recommended ("standard") follow-up schedule and to determine if certain patient characteristics correlate with the demand for these visits. A retrospective medical chart review of all PLC visits at an academic dermatology center from October 2010 to January 2012. A total of 609 patients associated with 1756 visits were identified. Of these, 25 patients associated with 26 visits were excluded owing to lack of melanoma diagnosis or risk factors, leaving 584 patients and 1730 visits. Diagnoses of these patients included in situ and invasive melanoma, dysplastic nevi, Spitz nevi, atypical nevus syndrome, family history of melanoma only, and other risk factors. The mean (SD) age was 48 (16) years, and 235 (40.2%) of the patients were male. The proportion of additional screening visits compared with standard visits. Standard visits were defined as occurring at the following frequencies: annually for mildly dysplastic nevi, Spitz nevi, or solely family history of melanoma; biannually for the first year, then annually thereafter for moderately dysplastic nevi or atypical nevus syndrome; biannually for up to 3 years, then annually thereafter for severely dysplastic nevi or melanomas in situ; every 3 months for 2 years, biannually for the following 2 years, then annually thereafter for invasive melanoma. A total of 1400 visits (80.9%) were standard, 257 (14.9%) were for additional screening, and 73 (4.2%) were "problem focused." Thirty percent of patients had at least 1 additional screening visit. The distribution of diagnoses among standard vs additional screening visits differed significantly, with "family history only" and "other risk factors" taking up a larger percentage of standard visits (15.1%) than the percentage of additional screening visits (8

Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital - including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome) - compressive - including 'nutcracker' syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital - including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome) - compressive - including 'nutcracker' syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

Multiple BAP1 negative melanocytic neoplasms are a hallmark of familial cancer susceptibility syndrome caused by BAP1 germline mutation. The syndrome is characterized by increased incidence of renal cell carcinoma, mesothelioma, cholangiocarcinoma, cutaneous and uveal melanoma and some other neoplasms. We report histomorphologic characteristics of six cutaneous melanocytic neoplasms with loss of BAP1 expression in two members of a family with BAP1-associated cancer susceptibility syndrome. The neoplasms were dermal melanocytic nevi characterized by a proliferation of large epithelioid (spitzoid) melanocytes, and adipocytic metaplasia. Nuclear pseudoinclusions and multinucleated melanocytes were present in most neoplasms. In two of the cases, a nodular melanoma was found associated with a dermal nevus. None of the melanomas recurred or metastasized after 6 and 3 years of follow up. We report two new cases of melanoma arising in a BAP1-deficient melanocytic nevus in the setting of familial tumor predisposition syndrome. Adipocytic metaplasia and nuclear pseudoinclusions may be additional morphologic clues to a BAP1-deficient nevus. It remains to be seen whether these features are more common in familial than sporadic lesions. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Purpose: Benign lesions are frequently develops in nevus sebaceous, while malignancies mayalso be seen rarely. We aimed to review the pathologies developed from nevus sebaceous in ourpatients. Material and method: Seven patients with nevus sebaceous, whose diagnoses andmanagements had been carried out in our department during the last six years, were reviewed.Diagnoses were verified by the examination of a pathologist. Results: In addition to the seven sebaceous nevi that were five in the scalp and two in the cheek,syringocystadenoma papilliferum in a patient, eccrine spiroadenoma in one patient, and bothsyringocystadenoma papilliferum and tubular apocrine adenoma in a patient were seen. Totalsurgical excision was performed for all patients. No recurrence was noticed in any of the tumorsin the follow-up. Conclusion: Prophylactic excision has been suggested because of the probable neoplastictransformations in elderly. In our series, early excision had been performed in almost all patientsand no malignant transformation was detected. Concerning the neoplastic changes are seenusually at the ages of 40-70 and aesthetically disturbing lesions rise in adolescent period, wesuggest that excision can be delayed to adolescent period.

The purpose of this study was to assess the efficacy of laparoscopic nephrectomy for a single-system ectopic ureter draining a dysplastic kidney in children. Between February 1999 and September 2005, 16 girls with a mean age of 6.2 years (range: 2-15 years) presented with urinary incontinence accompanied by regular voiding since birth (15 patients) and vaginitis (one patient). Ultrasonography, intravenous urography and a technetium-99m dimercaptosuccinic acid ( 99m Tc-DMSA) renal scan showed the presence of only a single kidney in all cases. Computed tomography (CT) showed a dysplastic kidney definitely in nine patients, structures suspicious of dysplastic kidney in three cases, and no dysplastic kidney in four cases. Magnetic resonance imaging was carried out in the four cases with non-visualized dysplastic kidneys by CT, and showed a suspicious lesion in only one case, and no lesion in the other three patients. All patients underwent transperitoneal laparoscopic nephrectomy for a dysplastic kidney. Laparoscopy identifies all dysplastic kidneys easily, even in those cases in which dystrophic kidney could not be identified by preoperative imaging. Dysplastic kidneys and ectopic ureters were removed successfully in all 16 patients. Mean operative time was 109 min (range: 40-155 min) with little intraoperative bleeding. Mean postoperative hospital stay was 2.6 days (range: 2-4 days). No intraoperative complication was encountered, except in one single case, in which a small bowel injury occurred during open Hasson's procedure. All patients became dry soon after the operation. Laparoscopic nephrectomy for an ectopic ureter draining into a dysplastic kidney is a safe and effective method, and can be carried out successfully, despite a failure by preoperative imaging studies to localize the dysplastic kidney.

Classical and molecular genetics of malignant melanoma and dysplastic naevi

Traupe, H.; Macher, E.

1988-01-01

The authors conclude that the prevailing concept of monogenic autosomaldominant inheritance of dysplastic naevi and familial melanoma is not compatible with the principles of formal (Mendelian) genetics. The concept of polygenic inheritance offers instead a sound basis to explain familial aggregation of dysplastic naevi and melanoma. The various genes involved have not yet been identified at the molecular level. The recent advances made possible by modern DNA technology have given us a new view of carcinogenesis. In human malignant melanoma, chromosomes 1, 6, 7 are of particular interest and oncogenes located on these chromosomes may be involved with the initiation, promotion and progression of melanoma. Carcinogenesis is viewed as a multistep process and even tumour initiation requires the input of at least two independent oncogenes. Molecular genetics thus adds an important argument for the existence of a polygenic predisposition to melanoma. The concept of polygenic inheritance is not restricted to familial melanoma, but implies that all melanomas basically share the same predisposition and are due to similar genetic mechanisms. In some patients an inherited genetic predisposition is of great importance, whereas in others (the majority) environmental factors (e.g. UV-light-induced mutations) will be the cause of initial steps in the malignant transformation. The concept of polygenic inheritance has consequences for the management of our patients. In contrast to simple Mendelian inheritance, the risk for dysplastic naevi and melanoma is not constantly 50%, but increases with the number of family members already affected. Persons belonging to families with more that 2 affected close relatives should be considered at high risk regardless of the dysplastic naevus status. Strict surveillance of this patient group is warranted for melanoma prevention

Bresler, Scott C; Padwa, Bonnie L; Granter, Scott R

2016-06-01

Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

2011-01-01

Full Text Available Epidermolytic hyperkeratosis presents with perinuclear vacuolization of the keratinocytes in spinous and granular layers, keratinocytes with ill-defined limits, which leads to a reticulate appearance of the epidermis, an increased number of variously shaped and sized basophilic keratohyalin granules and the same sized eosinophilic trichohyalin granules, at any level of epidermis, mainly in the stratum granulosum, and compact hyperkeratosis. This minor reactive pathologic reaction pattern of skin is found in large variety of diseases. This paper is the first case report of such pattern in inflammatory linear verrucous epidermal nevus. Our case is of a 23-year-old man with pruritic verrucous lesions of trunk and extremities initiated since 13 years ago. Physical examination revealed white linear hyperkeratotic lesions, some of them on erythematous background and also classic epidermal nevus. No skeletal, ophthalmic, and nervous system involvement was detected. Microscopic study of pruritic verrucous lesions showed psoriasiform acanthosis, mild papillomatous, hyperkeratosis, and epidermolytic hyperkeratotic changes in hair follicles and acrosyrinx accompanied with moderate perivascular inflammation.

A clinical and neurological study on the Sturge-Weber syndrome

1987-01-01

The author studied the relationship between facial nevus and intracranial changes seen on cranial computed tomography (CCT) scannings in 12 children with typical Sturge-Weber syndrome. The evaluation of epileptic attacks, repeat EEG and cranial CT examinations with or without enhancement during the follow-up period of 8 years in average were analysed. In 7 cases (58.3 %), the dominant side of facial hemangioma was identical with that of calcification on CCT. Three cases of central facial nevus showed calcification in one hemisphere, on either side. One who had facial nevus on one side showed dominant calcification on the other side on CT. The area and side of the facial nevus did not always coincide with those of the intracranial lesion. In 4 of the 9 patients who were followed up by repeat CCT, we recognized increases in degree of brain atrophy with or without increases in the area of calcification. In the enhancement study, 6 patients (89 %) showed positive choroid plexus images with abnormal enhancement on the same side as the calcification. On EEG 5 cases showed epileptiform activity over the hemisphere with calcification, and 3 showed it on the intact side of the brain. (author)

Joubert syndrome is a rare malformation of the posterior fossa, mainly affecting the cerebellar vermis, which generally appears as a dysplastic lesion. Other structures of the cervico medullary junction may be involved, with accompanying brainstem hypoplasia according to neuroimaging studies. The diagnosis is usually reached during, childhood, based on a constellation of changes in the child's neurological development that are supported by the results of imaging studied. Respiratory problems are the most common signs in newborns,leading to the suspicion of the presence of this syndrome. (Author) 11 refs

Simultaneous utilization of different nuclear medical examinations in a patient with Klippel-Trenaunay syndrome - vs. proteus syndrome

Rink, T.; Baum, R.P.; Hoer, G.; Menzel, I.; Niemczyk, M.; Kaufmann, R.; Fuchs, S.; Heller, K.

1997-01-01

A three-year-old male patient presented already at his birth a disproportional macrosomia of the left foot and a large, nodular nevus flammeus, in the left hip region, which led to the tentative diagnosis of a Klippel-Trenaunay syndrome. In the following years, both changes showed a continuous progression, with distinct soft-tissue swelling as well as papillomatous and verruciform vegetations of the nevus. Additionally, large, plain subcutaneous masses developed under the right shoulder, and a macrodactyly of the first and second left toe could be observed. Although several examinations had been performed in the meantime, the tentative diagnosis could not be confirmed up to that time. On the occasion of a severe local infection in the hip region, which led to the consideration of a surgical therapy, a radionuclide lymphography, a blood pool scintigraphy including dynamic phlebography and ventriculography as well as a bone scintigraphy were performed. These examinations were done simultaneously at one day in order to avoid a longer period of immobilization. The findings led to the diagnosis of a large lymphangioma, which could be confirmed histologically after surgery. In consideration of all results, the basic disorder seems to be the rare proteus syndrome rather than a Klippel-Trenaunay syndrome. (orig.) [de

Full Text Available A 23-year-old pregnant woman with an asymptomatic unilateral, bluish, pigmented lesion on her left periocular skin was referred from the obstetrics department for dermatological evaluation. Dermatologic examination revealed unilateral, blue-gray, poorly defined macule on the periorbital skin of the left side of the face mainly over the malar prominence and left temple not crossing the midline, conforming to the maxillary division of trigeminal nerve distribution. The pigmentation was speckled with interspersed dark-brownish elements. Her father, a 47 - year- old man had a similar pigmentation at the same site over the malar prominence of face not extending onto the forehead. Here we report two cases of nevus of Ota occurring in 2 generations of the same family for its rarity.

Full Text Available A case of a 41-year-old woman with a history of nodular melanoma (NM, associated with an indurated dome-shaped blue-black nodule with a diameter of 1.2 cm in the gluteal region, is presented. Clinical diagnosis of the lesion, present from birth, was blue nevus. Recently, the nodule has been showing a mild enlargement and thus complete resection was performed. Histological analysis revealed a pigmented lesion with an expansive pattern of extension into the dermis and the subcutaneous adipose tissue. The lesion displayed an alveolar pattern as well as a pigmented dendritic cell pattern. The histology was consistent with cellular blue nevus (CBN; however, the history of NM which was excised one year earlier, as well as the clinical information about the slow growing lesion, included a differential diagnosis of CBN, borderline melanocytic tumor, and malignant blue nevus. Additional immunohistochemical (HMB-45, p16, and Ki-67 and molecular (BRAF V600E mutation analyses were performed on both lesions: the CBN-like and the previously excised NM. Along with lesion history and histological analyses, p16 staining and BRAF were useful diagnostic tools for confirming the benign nature of CBN in this case.

A subset of facial melanoma in situ has histological features that overlap with those of "dysplastic" nevi. The authors evaluated this important diagnostic pitfall by assessing the frequency of melanoma as the final diagnosis in skin biopsies submitted over a 1-year period with a clinical impression of "atypical" or dysplastic nevus from the head or neck of adults. A total of 1998 biopsies met inclusion criteria. Final diagnoses included both melanocytic and nonmelanocytic processes. Clear trends were noted based on the age of the patient with benign nevi encompassing nearly 70% of specimens in patients aged 21-29 years and jawline; and 3, temple), a location not traditionally associated with atypical nevi. Facial atypical nevi were found in all age groups. Malignant melanoma accounted for 1.8% of all specimens increasing from 0% in the patients aged 21-29 years to 5% in patients aged 70 years and above. Caution is warranted when evaluating skin biopsies from sun-damaged skin of the head or neck of an older adult submitted with a clinical diagnosis of atypical nevus. However, the authors' findings suggest that atypical nevi with histological features of dysplastic nevi occur on the head and neck of adults, including elderly adults. The incidence of such lesions decreases with age as the incidence of melanoma increases, and careful clinicopathologic correlation is vital.

Desde su nacimiento presentó nevus melanocítico gigante localizado en región torácica posterior, región lumbosacra y lesiones satélites en extremidades y abdomen, de 50 por 40cm de diámetro y color café oscuro; la piel en las zonas afectadas es gruesa con grandes surcos de aspecto corrugado (cerebriforme. El nombre dado al niño se basa en la similitud de sus lesiones con la morfología de una tortuga, ya que el caparazón cubre la zona superior, inferior y lateral del cuerpo de este animal, de la misma forma que el nevus gigante lo hacía en el caso de nuestro paciente. Este caparazón está formado por placas óseas revestidas de placas corneas, que se asemejan a los surcos de aspecto corrugado que conforman el nevus melanocítico gigante. Los estudios clínicos practicados revelaron compromiso cardiovascular, hepático y esplénico, así como una desfavorable evolución y pronostico del cuadro clínico, por lo que esta patología, específicamente para este niño y de acuerdo a la junta Médico-Quirúrgica y valoraciones, fue considerada inoperable.We present the case of a 2 years-old patient, known in his town as "turtle boy"(testudines due to his great simility with this reptile because of his giant congenital melanocytic nevus, located in the posterior and lateral aspect of the chest and in smaller proportion in abdomen and extremities, of 50 by 40cm and dark brown colour. The skin in this zone is thick with great furrows and corrugated aspect. He was called "turtle boy" based on the morphology of the turtle, its shell covers the superior, inferior and lateral zone like in our patient's case.

Full Text Available El nevus blanco esponjoso (NBE es una rara condición autosómica dominante, caracterizada por placas blancas bilaterales en la mucosa, de aspecto esponjoso, blandas a la palpación y que pueden escamarse. Los tratamientos son paliativos; y el uso de antibióticos, en especial la tetraciclina, ha demostrando buenos resultados en su control. Este trabajo presenta tres casos clínicos de una familia afectada por NBE, donde se discuten los posibles diagnósticos diferenciales y conductas terapéuticas indicadas. Un paciente masculino de 52 años de edad acudió a la clínica aquejado de lesiones blancas bilaterales. El paciente notó las lesiones 30 años antes, sin lograr un diagnóstico final de las mismas. Después de la anamnesis y del examen clínico fue realizada una biopsia incisional. La reunión de los datos clínicos e histopatológicos llevó al diagnóstico de NBE. Se le solicitó al paciente que indagase entre sus familiares con respecto a lesiones semejantes. Se detectó que el hijo de 19 años y la hija de 25 eran portadores de placas blancas en la mucosa yugal. Como no había afectación estética, se optó por no intervenir en las lesiones. El nevus blanco esponjoso es una lesión genética que debe ser diferenciada de otras patologías localizadas y sistémicas importantes, que tienen repercusiones serias para el individuo. Como no hay un tratamiento curativo para el NBE, el papel del cirujano dentista es diagnosticar esta lesión, aclarar al paciente sobre la naturaleza benigna y autolimitante del NBE y si fuera necesario desde el punto de vista estético, aplicar diferentes modalidades terapéuticas.

Spitz nevus arising in the eyelid of a teenager.

Shields, Patrick W; Jakobiec, Frederick A; Stagner, Anna M; Yoon, Michael K

2016-01-01

A 16-year-old boy developed over a 2-month interval a lightly pigmented left upper eyelid lesion measuring 1.5 mm in greatest diameter that, when excised, microscopically was hypercellular and composed almost exclusively of nonpigmented epithelioid cells that created florid, large intraepidermal junctional nests and sheets and nests of subepidermal cells. The diagnosis was a Spitz nevus. HMB-45, MART-1, and microphthalmia-associated transcription factor were all positive and established the melanocytic nature of the benign tumor. The Ki-67 proliferation index (5%) and 2 mitoses/mm(2) were both low; p16 protein was immunohistochemically identified in the nevoid cells. We review the clinical, histopathologic, and other immunohistochemical features of this entity and provide a brief differential diagnosis (including separation from a Spitzoid melanoma). This is only the third eyelid Spitz nevus reported in the literature and is the most fully characterized immunohistochemically. At their present stage of development, contemporary immunohistochemical biomarkers, while providing supplemental information, nonetheless remain less than definitive in terms of reliably distinguishing benign from malignant Spitz lesions.

Full Text Available Background. The prevalence and severity of stage II and III dysplastic coxarthrosis determine the medical and social importance of its prevention and treatment. For a practicing orthopedic surgeon, there are two established stages of orthopedic treatment: the surgical stage and the restorative stage. The domestic and foreign literature from the previous 25 years comprises few publications regarding the rehabilitation of young children after reconstructive hip joint surgeries. Thus, the issues regarding the rehabilitation of teenagers following extra-articular operations on the hip joint remain unexplored. Aim. To evaluate the effectiveness of the developed program of rehabilitation for children after the surgical treatment of dysplastic coxarthrosis stages I and II. Material and methods. We analyzed the results of the surgical and rehabilitative treatment of 40 children (100% with dysplastic coxarthrosis stage I and II; the study population included 27 girls (67.5% and 13 boys (32.5 per cent aged 13–18 years (total 54 joints. The rehabilitation period was divided into the following 4 stages: I preoperative, II postoperative day 1–2, III postoperative day 3–21, IV outpatient treatment (after hospital discharge to 1 year postoperatively. Results. By the time of discharge, the range of motion in the hip joint was as follows: bending 950° ± 40°, withdrawal 150° ± 50°, and extension 100° ± 30°. According to the results of the electromyography performed 3 months postoperatively, there was an increase in the amplitude of biopotentials for the gluteal muscle. The long-term result was evaluated after 1 year. The average modified Harris Hip Score and a scale developed in the The Turner Scientific and Research Institute for Children’s Orthopedics, significantly (p < 0.05 differed from preoperative ones. Conclusion. Early rehabilitation allows an increase in the strength and tone of muscles and restores the amplitude of movements in

The purpose of this study was to retrospectively analyze the clinical characteristics of treating nevus of Ota by Q-switched Nd:YAG laser in Laser Cosmetology Center of Department of Dermatology, the Second Hospital, Xi'an Jiaotong University. The data of 1168 patients of nevus of Ota were analyzed retrospectively, which included the correlation among lesion color, treatment sessions, sex, age, lesion types, and effect. The Q-switched (QS) Nd:YAG laser system had a higher number of treatment sessions which were positively associated with a better response to treatment. Other variables, including gender, age, the categorization of the lesion according to Tanino's classification, and the color of the lesion, were not associated with the response to treatment. The treatment of nevus of Ota with QS Nd:YAG laser is safe and effective, with rare complications.

The authors hypothesise that the trochlear dysplastic distal femur is not only characterised by morphological changes to the trochlea. The purpose of this study is to describe the morphological characteristics of the trochlear dysplastic femur in and outside the trochlear region with a landmark-based 3D analysis. Arthro-CT scans of 20 trochlear dysplastic and 20 normal knees were used to generate 3D models including the cartilage. To rule out size differences, a set of landmarks were defined on the distal femur to isotropically scale the 3D models to a standard size. A predefined series of landmark-based reference planes were applied on the distal femur. With these landmarks and reference planes, a series of previously described characteristics associated with trochlear dysplasia as well as a series of morphometric characteristics were measured. For the previously described characteristics, the analysis replicated highly significant differences between trochlear dysplastic and normal knees. Furthermore, the analysis showed that, when knee size is taken into account, the cut-off values of the trochlear bump and depth would be 1 mm larger in the largest knees compared to the smallest knees. For the morphometric characteristics, the analysis revealed that the trochlear dysplastic femur is also characterised by a 10% smaller intercondylar notch, 6-8% larger posterior condyles (lateral-medial) in the anteroposterior direction and a 6% larger medial condyle in the proximodistal direction compared to a normal femur. This study shows that knee size is important in the application of absolute metric cut-off values and that the posterior femur also shows a significantly different morphology.

Dysplastic vs. Common Naevus-associated vs. De novo Melanomas: An Observational Retrospective Study of 1,021 Patients

Full Text Available The aim of this case-case study was to determine the differences between dysplastic and common naevus-associated melanomas (NAM and de novo melanomas. A total of 1,021 prospectively collected patients with invasive cutaneous melanoma from an oncology referral centre were included in the study. Of these, 75.51% had de novo melanomas, 12.93% dysplastic NAM, and 11.56% common NAM. Dysplastic NAM, compared with de novo melanomas, were associated with intermittently photo-exposed sites, atypical melanocytic naevi, decreased tumour thickness, and presence of MC1R non-synonymous variants. Common NAM were more frequent on the trunk and of superficial spreading type. Comparison of dysplastic with common NAM showed significant difference only with regard to mitoses. Both subtypes of NAM shared less aggressive traits than de novo melanomas, albeit with no significant differences in survival after multivariate adjustment. In conclusion, NAM present with less aggressive traits, mostly due to a greater awareness among patients of changing moles than due to their intrinsic biological characteristics.

Giant congenital melanocytic nevus (GCMN) is rare in babies of African descent. Unfortunately, it has an increased potential for malignant transformation. A 3-year-old female child presented with a 6-month history of multiple nodules on an existing giant congenital melanocytic nevus and swelling in the right axilla of four weeks duration. Skin biopsy of the nodular skin lesions was in keeping with a metastatic malignant melanoma (Clark stage 4). She completed a full course of chemotherapy but subsequently died four months after presentation. Patients with large GCMN should be counseled and followed up appropriately to improve and prolong life. © 2014 The International Society of Dermatology.

To determine the immediate and intermediate outcome in dysplastic and doming pulmonary valve stenosis in children and to determine various factors associated with unsuccessful outcome. Study Design: An interventional study. Place and Duration of Study: The Children's Hospital, Lahore, Pakistan, from June 2006 to December 2012. Methodology: All patients presenting with severe pulmonary valve stenosis were enrolled in the study. Balloon valvuloplasty was performed on all patients. Successful outcome (residual gradient 75 mmHg was the most significant factor associated with unsuccessful outcome (p 60 mmHg was the only significant factor associated with re-intervention in group A (p=0.001). Conclusion: The results from balloon valvuloplasty in dysplastic pulmonary valve were suboptimal when compared to doming valves. However, it provides a high freedom from re-intervention rate in intermediate follow-up. Intervention at moderate severity can result in better outcome. (author)

[Congenital "kissing" lesions: Nevus or "café au lait" spot?

Science.gov (United States)

"Café au lait" spots (CLS) are pigmented skin lesions principally located at the trunk and the limbs. Histologically, CLSs consist in an excessive pigmentation of the epidermis, with no risk of malignant transformation. The "kissing" nevus is a rare pigmented congenital nevus affecting both lower and upper eyelids in a mirror layout. As other nevi, it presents a theoretical risk of malignant transformation. These two pigmented lesions are responsible for aesthetic discomfort when affecting the face. Three patients presenting with a congenital pigmented lesion affecting the two eyelids in a mirror layout are presented. In two cases, the lesions, initially considered as "kissing" nevi, were classified as CLSs. The diagnosis of CLS was made on a biopsy in one patient and after surgery in the other one. Pigmented mirror layout lesions, called "kissing" lesions, are exclusively described for the nevi. We describe two cases of CLSs affecting the eyelids in a mirror layout. Difficulties in diagnostic are exposed and the possible treatments are discussed. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

2015-03-01

Gorlin-Goltz syndrome or basal cell nevus syndrome is a comparatively rare syndrome characterized by basal cell nevi, odontogenic keratocysts, and skeletal anomalies. Diagnosis is based on the major and minor clinical and radiographic criteria. Dentist plays a major role in the diagnosis of this disease due to the oral and maxillofacial manifestations of the syndrome. In some cases, jaw cysts are diagnosed by routine radiographs advised by the dentists. Odontogenic keratocysts in such syndromic patients will be multiple and extensive and in some cases results in cortical expansion and facial disfigurement. Thorough clinical examination and investigations prompt an early confirmation of the syndrome, which is very essential to avoid morbidity associated with the syndrome. Here, we report a case of multiple odontogenic cysts in a 16-year-old patient which later was diagnosed as a case of Gorlin Goltz syndrome.

Full Text Available We present a  clinical case of ichthyosis hystrix, a rare genetic ichthyosiform dermatosis. Specifics of the disease are related to the complexity of differential diagnosis and verification of the diagnosis, because clinical manifestation of ichthyosis hystrix is similar with that of verrucous epidermal nevus. Clinical particulars of both nosologies are characterized by bizarre and widespread skin lesions of spicular hyperkeratotic growth, located along Blaschko lines. The exclusive feature of the clinical case described is a  long-term (20 years clinical and laboratory monitoring of the patient. The literature review provides brief information on etiology, pathogenesis, clinical features, differential diagnosis, and pathomorphology of ichthyosis hystrix and verrucous epidermal nevus.

Malignant melanoma - a warning

Incidence of malignant melonoma of the skin has risen rapidly during the last decades. Mortality rates are also rising, although not so much as incidence rates. There is strong evidence that exposure to sunlight is a major factor in the etiology of melanomas. There appears to be no direct cumulative dose-response relationship, except in the case of lentigo maligna melanoma. Episodes of sunburn among children and young individuals seem to be more important as an etiologic factor for melanoma than chronic exposure to the sun. Very high risk of melanoma exists in persons with dysplastic nevus syndrome. Persons with giant congenital nevi are also at increased risk. However, many melanomas arise de novo. The intension of the authors is to reduce mortality by screening families at risk, by early detection and treatment of melanomas, and by education. 15 refs., 2 tabs

Full Text Available A giant congenital melanocytic nevus represents a rare condition. The halo phenomenon may be seen in congenital or acquired melanocytic nevi. In the literature, association of halo nevus and giant congenital melanocytic nevus is rare and the association of both with vitiligo even more rare. A 75-yearold woman at first consultation complained of a hyperchromic bluish-brown hairy macula on the lower back, buttocks and thighs present since birth and an achromic halo of onset three years ago. The histological features were consistent with congenital melanocytic nevus and halo nevus, respectively. After two years the patient developed achromic areas in normal skin, histologically consistent with vitiligo. The authors emphasize the rarity of this triple combination, the patient's age and the absence of malignant degeneration to date.Nevo melanocitico congênito gigante constitui uma condição rara. O fenômeno halo pode ser observado em nevos melanocíticos congênitos ou adquiridos. Na literatura a associação nevo halo e nevo melanocítico congênito gigante é rara e a associação de ambos com vitiligo ainda mais rara. Mulher de 75 anos que à primeira consulta apresentava mácula hipercrômica castanho-azulada pilosa na região lombar, nádegas e coxas desde o nascimento e halo acrômico de aparecimento há 3 anos. Os histológicos foram compatíveis com nevo melanocítico congênito e nevo halo respectivamente. Após dois anos evoluiu com áreas de acromia à distância, com histológico de vitiligo. Os autores ressaltam a raridade desta tripla associação; a idade da paciente e a ausência de degeneração maligna até o presente momento.

We present a dermal melanocytosis with superimposed nevus spilus on the arm of a 5-year-old boy. We recently introduced a new type of phacomatosis, which we termed "phacomatosis pigmentopigmentalis," that is analogous to phacomatosis pigmentokeratotica or pigmentovascularis, for describing the association of two pigmented nevi. The present case is an example of this type of phacomatosis, which now we prefer to define phacomatosis pigmento-pigmentaria according to the correct Latin terminology.

Histopathological interpretation of proliferative nodules occurring in association with congenital melanocytic nevi can be very challenging due to their similarities with congenital malignant melanoma and malignant melanoma arising in association with congenital nevi. We hereby report a diagnostically challenging case of congenital melanocytic nevus with proliferative nodules and ulcerations, which was originally misdiagnosed as congenital malignant melanoma. Subsequent histopathological examination in consultation by one of the authors (R.L.) and mass spectrometry imaging analysis rendered a diagnosis of congenital melanocytic nevus with proliferative nodules. In this case, mass spectrometry imaging, a novel method capable of distinguishing benign from malignant melanocytic lesions on a proteomic level, was instrumental in making the diagnosis of a benign nevus. We emphasize the importance of this method as an ancillary tool in the diagnosis of difficult melanocytic lesions.

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome characterized by a facial nevus flammeus associated with seizures, developmental delay, and, often, with hemiparesis and hemianopia. On MRI, the most characteristic finding has been reported to be leptomeningeal enhancement, believed to represent leakage of contrast medium through the anomalous pial vessels that characterize the disease. We present a case of SWS with no evidence of leptomeningeal enhancement. This case illustrates that leptomeningeal enhancement need not be present in SWS, and the absence of this characteristic finding does not preclude the diagnosis. (orig.) With 2 figs.

2011-01-01

In several human volunteers, photoacoustic microscopy (PAM) has been utilized for noninvasive cutaneous imaging of the skin microvasculature and a melanocytic nevus. Microvascular networks in both acral and nonacral skin were imaged, and multiple features within the skin have been identified, including the stratum corneum, epidermal-dermal junction, and subpapillary vascular plexus. Several vascular and structural differences between acral and nonacral skin were also observed in the photoacoustic images. In addition, a nevus was photoacoustically imaged, excised, and histologically analyzed. The photoacoustic images allowed for in vivo measurement of tumor thickness, depth, and microvasculature-values confirmed by histologic examination. The presented images demonstrate the potential of PAM to aid in the study and evaluation of cutaneous microcirculation and analysis of pigmented lesions. Through its ability to three-dimensionally image the structure and function of the microvasculature and pigmented lesions, PAM can have a clinical impact in diagnosis and assessment of systemic diseases that affect the microvasculature such as diabetes and cardiovascular disease, cutaneous malignancies such as melanoma, and potentially other skin disorders.

Full Text Available Nevoid basal cell carcinoma syndrome (BCNS is an autosomal dominant inherited disorder. Multiple organ systems may be affected in this syndrome including abnormalities of the skin, skeletal system, genitourinary system and central nevus system. In this report, we present a case of Nevoid basal cell carcinoma syndrome in a 26-year-old male patient. The patient had multiple odontogenic keratocyst in the posterior of mandible, syndactyly in both hand and bifid rib. After enucleation and curettage, he was followed for two years. A number of both clinical and radiological criteria are used to diagnose this syndrome. Basal cell carcinoma syndrome is diagnosed with two major criteria or one major and two minor criteria. We must suspect this disorder in young patients with multiple odontogenic keratocyst and dental abnormalities whether related or not with other clinical manifestations or familial history.

Segmentation and computer assisted design tools have the potential to test the validity of simulated surgical procedures, e.g., trochleoplasty. A repeatable measurement method for three dimensional femur models that enables quantification of knee parameters of the distal femur is presented. Fifteen healthy knees are analysed using the method to provide a training set for an artificial neural network. The aim is to use this artificial neural network for the prediction of parameter values that describe the shape of a normal trochlear groove geometry. This is achieved by feeding the artificial neural network with the unaffected parameters of a dysplastic knee. Four dysplastic knees (Type A through D) are virtually redesigned by way of morphing the groove geometries based on the suggested shape from the artificial neural network. Each of the four resulting shapes is analysed and compared to its initial dysplastic shape in terms of three anteroposterior dimensions: lateral, central and medial. For the four knees the trochlear depth is increased, the ventral trochlear prominence reduced and the sulcus angle corrected to within published normal ranges. The results show a lateral facet elevation inadequate, with a sulcus deepening or a depression trochleoplasty more beneficial to correct trochlear dysplasia.

Full Text Available Los nevus melanocíticos gigantes congénitos son muy infrecuentes. Su incidencia de malignización varía según las series clínicas entre el 2 y el 45%. Este riesgo de malignización y los problemas de adaptación psicosocial que suelen acarrear hacen recomendable el inicio del tratamiento quirúrgico de este tipo de lesiones antes de la edad escolar. Presentamos el caso de un niño de 7 años de edad con nevus melanocítico congénito gigante que afectaba a la espalda y al flanco derecho, de 30 x 19 cm de diámetro. Desarrollamos un protocolo terapéutico mediante programación de intervenciones quirúrgicas seriadas de mínima morbilidad, con postoperatorio simple y poco doloroso. En un primer tiempo realizamos extirpación de la lesión con bisturí ultrasónico y cobertura temporal del defecto creado con dermis artificial. En un segundo tiempo intentamos cobertura definitiva con piel cultivada autóloga, siendo necesario un tercer tiempo de cobertura con autoinjerto de espesor ultrafino. En este caso, el sistema de terapia de presión negativa VAC® mostró su eficacia para inmovilizar los apósitos de forma segura, indolora y en régimen ambulatorio.Giant congenital melanocytic nevi are very uncommon. Malignization incidence varies according to clinical series between 2 and 45%. This risk of malignization and psychosocial adaptation problems make necessary to begin the surgical treatment before school age. We present a 7-year-old child with a giant melanocytic nevus in the back and right flank, 30 x 19 cm in size. A therapeutic protocol using serial surgical interventions with minimal morbidity and an easy and painless postoperative care were developed. In the first surgery we removed the nevus with ultrasonic scalpel and used artificial dermis as a temporary coverage. In the second time we tried to complete the definitive coverage with autologous cultured skin, but we needed a third time to apply definitive ultrathin skin autograft. In

Studies of morphology of myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) refer to the definitions produced by the French-American-British (FAB) group and by the World Health Organization expert group. To clarify some points regarding the dysgranulopoiesis that are still unclear we analyzed a series of 98 neutrophils from MDS patients with regard to granularity, nuclear segmentation, the appearance of the chromatin, the presence of giant neutrophils, and the presence of nuclear chromatin extensions. We found that cells with at least 2/3 reduction of the content of granules, Pelger-like neutrophils, dysplastic non-Pelger cells, neutrophils with abnormal clumping of the chromatin, and macropolycytes could be recognized as dysplastic and included in the 10% count recommended by these two classifications. In addition, we suggest that neutrophils with more than 4 nuclear projections could be recognized as a relevant dysplastic feature. Copyright © 2013 Elsevier Ltd. All rights reserved.

UVA affects epidermal cell physiology in a complex manner, but the harmful effects have been studied mainly in terms of DNA damage, mutagenesis and carcinogenesis. We investigated UVA effects on membrane integrity and antioxidant defense of dysplastic keratinocytes after one and two hours of irradiation, both immediately after exposure, and 24 h post-irradiation. To determine the UVA oxidative stress on cell membrane, lipid peroxidation was correlated with changes in fatty acid levels. Membrane permeability and integrity were assessed by propidium iodide staining and lactate dehydrogenase release. The effects on keratinocyte antioxidant protection were investigated in terms of catalase activity and expression. Lipid peroxidation increased in an exposure time-dependent manner. UVA exposure decreased the level of polyunsaturated fatty acids, which gradually returned to its initial value. Lactate dehydrogenase release showed a dramatic loss in membrane integrity after 2 h minimum of exposure. The cell ability to restore membrane permeability was noted at 24 h post-irradiation (for one hour exposure). Catalase activity decreased in an exposure time-dependent manner. UVA-irradiated dysplastic keratinocytes developed mechanisms leading to cell protection and survival, following a non-lethal exposure. The surviving cells gained an increased resistance to apoptosis, suggesting that their pre-malignant status harbors an abnormal ability to control their fate. PMID:23222638

Acetabular dysplasia is one of the most common sources of hip arthritis. With the recent innovation in hip arthroscopy, the question has been raised whether arthroscopy can be used to treat dysplastic hip conditions. The purposes of this systematic review are (i) describe the prevalence of intra-articular pathologies and (ii) report the outcomes of dysplastic hip treatment with hip arthroscopy as a sole treatment. Medical databases were searched for articles including arthroscopic findings and treatment of dysplastic hip with predetermined criteria. PubMed, Ovid database and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched up until 7 January 2015. Two reviewers independently assess the eligibility of retrieved studies using titles, abstracts and full-text articles. Thirteen studies were eligible to be included for the systematic review. Overall, labral tear was the most common pathology with a prevalence rate of 77.3%. All of the four studies describing arthroscopic treatment for only borderline dysplasia reported favorable outcome. With regard to more severely dysplastic hips, two out of three studies reported acceptable outcomes while one study reported negative results. This review indicates that intra-articular pathology is commonly observed in symptomatic dysplastic hips with a labral tear being the most common pathology. Arthroscopic treatment of borderline dysplasia could provide benefits whereas treatment of more dysplastic hips is controversial. Nevertheless, there is a lack of evidence for using arthroscopy alone in hips with a center edge angle <20°. Level IV, systematic review of Level IV studies. PMID:27583155

Spondylolysis is a fracture in part of the vertebra with a reported prevalence of about 3-6% in the general population. Genetic etiology of this disorder remains unknown. The present study was aimed at identifying genomic mutations in patients with dysplastic spondylolysis as well as the potential pathogenesis of the abnormalities. Whole-exome sequencing and functional analysis were performed for patients with spondylolysis. We identified a novel heterozygous mutation (c.2286A > T; p.D673V) in the sulfate transporter gene SLC26A2 in five affected subjects of a Chinese family. Two additional mutations (e.g., c.1922A > G; p.H641R and g.18654T > C in the intron 1) in the gene were identified by screening a cohort of 30 unrelated patients with the disease. In situ hybridization analysis showed that SLC26A2 is abundantly expressed in the lumbosacral spine of the mouse embryo at day 14.5. Sulfate uptake activities in CHO cells transfected with mutant SLC26A2 were dramatically reduced compared with the wild type, confirming the pathogenicity of the two missense mutations. Further analysis of the gene-disease network revealed a convergent pathogenic network for the development of lumbosacral spine. To our knowledge, our findings provide the first identification of autosomal dominant SLC26A2 mutations in patients with dysplastic spondylolysis, suggesting a new clinical entity in the pathogenesis of chondrodysplasia involving lumbosacral spine. The analysis of the gene-disease network may shed new light on the study of patients with dysplastic spondylolysis and spondylolisthesis as well as high-risk individuals who are asymptomatic.

The purpose of this study was to evaluate ultrasound, MRI, and CT investigations in children with Sturge-Weber syndrome. From 1996 to 2005, a total of 15 investigations of the brain performed in 6 children with Sturge-Weber syndrome were reviewed. We evaluated four ultrasound, five CT, and six MRI exams. With ultrasound an increase of the echogenicity of the periventricular white matter was depicted in the first days of life. MRI is the best modality to demonstrate the vascular malformation, the impaired cerebral venous drainage, and the atrophy of one hemisphere. One-sided periventricular hyperechogenicity on ultrasound can be an early sign of Sturge-Weber syndrome in children with a nevus flammeus. MRI is the method of choice to diagnose Sturge-Weber syndrome and to follow up these children if the neurological status of the patients changes. (orig.) [de

A severely growth retarded baby was born at 38 weeks gestation. He had multiple craniofacial anomalies, microbrachycephaly, phocomelia in the upper limbs and renal cysts visible on ultrasound. He died of recurrent apneas. The autopsy showed left sided multicystic dysplastic kidney and absence of one testis. Cytogenetic studies did not reveal any abnormality. The phenotypic features match those described in the Roberts-SC phocomelia syndrome. A literature review revealed that 50% of these patients have chromosomal defects and antenatal detection is possible on ultrasound and by chromosome analysis of the amniocytes.

Basal cell carcinoma (BCC) is the most common skin cancer worldwide with increasing incidence, but difficult to assess due to the current under registration practice. Despite the low mortality rate, BCC is a cause of great morbidity and an economic burden to health services. There are several risk factors that increase the risk of BCC and partly explain its incidence. Low-penetrance susceptibility alleles, as well as genetic alterations in signaling pathways, namely SHH pathway, also contribute to the carcinogenesis. BCC associate with several genetic syndromes, of which basal cell nevus syndrome is the most common.

Nevoid basal cell carcinoma syndrome is a syndrome with wide variety of manifestations ranging from oral lesions to skeletal deformities. It calls for due responsibility of maxillofacial surgeon to diagnose the syndrome because very often they are the first health professionals to see the patient for the treatment of keratocystic odontogenic tumor. Keratocystic odontogenic tumor has been the topic of numerous investigators, is known for its potentially aggressive behavior, significant rate of recurrences. KCOT often occurs as a solitary lesion, in some instances multiple keratocysts may occur in association with a syndrome called Gorlin-Goltz syndrome (nevoid BCC, jaw cyst bifid rib basal cell nevus syndrome). Here, we present a case of multiple keratocysts in the mandible in association with skeletal, ocular, cutaneous anomalies in the given clinical scenario, which has profound relevance in the clinical dental practice.

Highlights: • VEGFR-2-expression levels vary between HCC, dysplastic and regenerative liver nodules. • Perfusion parameters vary between these groups in blood flow, blood volume and HPI. • Strong correlations were observed between perfusion parameters and VEGFR-2-expression. • The results might influence diagnosis and therapy of anti-vascular therapeutic regimes. - Abstract: Purpose: To evaluate whether VEGFR-2-expression in hepatocellular carcinoma (HCC), dysplastic (DLN) and regenerative liver nodules (RLN) correlates with pre-histology, in vivo Dynamic Contrast Enhanced-Computed Tomography (DCE-CT) data as VEGFR-2-expression affects prognosis and therapeutic options. Materials and methods: 34 patients (63.6 ± 8.9 years, 7 females) underwent liver biopsy or surgery due to suspected HCC or dysplastic nodules after DCE-CT between 2009 and 2015 with no previous chemo- or interventional therapy. Immunohistochemistry staining for VEGFR-2 was performed using Immunoreactive-Remmele-Stegner-Score (IRS) for quantification. A 128-row CT-scanner was used for DCE-CT with assessment of perfusion parameters blood flow (BF), blood volume (BV), arterial liver perfusion (ALP), portal venous perfusion (PVP), and hepatic perfusion index (HPI). Results: Histology confirmed HCC (n = 10), DLN (n = 7) and RLN (n = 34). Mean IRS for VEGFR-2 in HCCs was 9.1 ± 3.0, 7.3 ± 1.6 for DLN and 5.2 ± 2.8 for RLN (p = 0.0004 for HCC vs. RLN). Perfusion values varied significantly between all three groups for BF and HPI (p < 0.001 and p < 0.0001) and for BV in HCC vs. RLN (p < 0.0001) and DLN vs. RLN (p = 0.0019). Strong correlations between VEGFR-2-IRS and perfusion parameters were observed for BF in HCC (r = 0.88, p < 0.01) and HPI in HCC and DLN (r = 0.85, p < 0.04; r = 0.9, p < 0.01). Conclusion: Immunostaining revealed different VEGFR-2-expression levels in HCC, dysplastic and regenerative liver nodules. Perfusion markers blood flow, blood volume and hepatic perfusion index

The authors make a survey of a series of a hundred Becker's nevi diagnosed in a recruiting center of the French National Service. It is a statistic study bearing on the male population, aged 17 to 26, in a French region which is supposed to be representative of the French male population of the same age. First of all the authors focus on the various clinical descriptions since this nevus was first described by Becker in 1949, then discuss the problems raised by pathogenic interpretation and the results of microscopic studies. About this lesion, usually said to be pigmentary and hairy, and generally appearing before 20 years of age, is still very little known. Then after a short explanation of their method of study the authors give original results. A hundred Becker's nevi were diagnosed among 19,302 young men, that is to say in a proportion of 0.52 p. 100. A study of the racial, genetic and pigmentary background doesn't enable to retain general causes but rather leads to think of local causes. Half of these Becker's nevi appeared before ten years of age, the other half appearing between 10 and 20. In only one quarter of the cases can the role of the sun be pointed out. The location of the nevi is variable; they are mainly situated on the trunk and only 32 p. 100 of them are located above nipples, which was believed to be the usual place of the lesion. Pigmentation in three quarter of the cases is light brown. The average surface is 125 cm2. Hairs can be seen in only a little more than half of the cases of no lesion associated to the nevus could be found. The study points out that Becker's nevi seem to be more various in their clinical expression and more pigment than could be thought through more classical description.

Pigmented epithelioid melanocytoma (PEM) is a tumor encompassing epithelioid blue nevus of Carney complex (EBN of CNC) and was previously termed animal-type melanoma. Histologically PEMs are heavily pigmented spindled and epithelioid dermal melanocytic tumors with infiltrative borders, however, their origin remains unclear. Stem cells for the epidermis and hair follicle are located in the bulge area of the hair follicle with the potential to differentiate into multiple lineages. Multiple cutaneous carcinomas, including follicular cutaneous squamous cell carcinoma (FSCC), are thought to arise from stem cells in the follicular bulge. We present two cases of PEM/ATM in a 63 year-old male on the scalp with follicular origin and a 72 year-old female on the upper back arising in an intradermal nevus. Biopsy of both cases revealed a proliferation of heavily pigmented dermal nests of melanocytes with atypia. The Case 1 tumor was in continuation with the outer root sheath of the hair follicle in the bulge region. Case 2 arose in an intradermal melanocytic nevus. Rare mitotic figures, including atypical mitotic figures, were identified in both cases. We present two cases of PEM, with histologic evidence suggesting two origins: one from the follicular bulb and one from an intradermal nevus.

The case of a 24-year-old man with Hadju-Cheney syndrome is reported. No similar disease occured in his family. Inverted and bulbous tips of fingers were noted at age 9 and protruded occipital bone at age 10. He complained of left facial spasm and facial tics for 1 year. Examination revealed a man of short stature, with a brachycephalic skull and hypertelorism. Radiologically there was an extreme degree of basilar impression with the basal angle of 180 degrees, demineralized spinal vertebrae, and acro-osteolysis. Both bone and CT scans demonstrated the abnormalities of the skull clearly. The basilar artery ran almost horizontally on angiography. He gradually deteriorated neurologically with bulbar, pyramidal and cerebellar signs and symptoms. Review of the literature revealed at least then non-familial and nine familial cases of this disorder. It is considered that this syndrome is a genetically determined generalized dysplastic bone disorder. (orig.)

Mazabraud's syndrome is a rare disorder characterized by the association of single or multiple intramuscular myxomas with fibrous dysplasia. Here, we present the first case of Mazabraud's syndrome visualized on 18F-FDG PET/CT with histopathological confirmation of the myxoma. Our case demonstrates a slightly increased FDG uptake (SUVmax 2.1) within the myxomas and a moderately to highly increased tracer uptake (SUVmax 7.0) within the fibrous dysplastic lesions. The typical histological appearance of the intramuscular myxoma confirmed the radiological diagnosis. Further, we discuss the imaging findings and the histopathological features of this rare case with a review of the related literature

In the recent years, there has been a considerable surge in the application of spectroscopy for disease diagnosis. Raman and fluorescence spectra provide characteristic spectral profile related to biochemical and morphological changes when tissues progress from normal state towards malignancy. Spectroscopic techniques offer the advantage of being minimally invasive compared to traditional histopathology, real time and quantitative. In biomedical optical diagnostics, freshly excised specimens are preferred for making ex-vivo spectroscopic measurements. With regard to fresh tissues, if the lab is located far away from the clinic it could pose a problem as spectral measurements have to be performed immediately after dissection. Tissue samples are usually placed in a fixative agent such as 4% formaldehyde to preserve the samples before processing them for routine histopathological studies. Fixation prevents the tissues from decomposition by arresting autolysis. In the present study, we intend to investigate the possibility of using formalin fixed samples for discrimination of brain tumours from dysplastic tissue using Raman and fluorescence spectroscopy. Formalin fixed samples were washed with phosphate buffered saline for about 5 minutes in order to remove the effects of formalin during spectroscopic measurements. In case of fluorescence spectroscopy, changes in spectral profile have been observed in the region between 550-670 nm between dysplastic and tumor samples. For Raman measurements, we found significant differences in the spectral profiles between dysplasia and tumor. In conclusion, formalin fixed samples can be potentially used for the spectroscopic discrimination of tumor against dysplastic tissue in brain samples.

From the first recognition of dysplastic nevi as a pathology per se, many debates have been raised and many histological and immunohistological studies have been conducted in order to establish the true significance of these lesions. Therefore, the aim of this study was to establish if there is a correlation between HMB-45, Melan A and Bcl-2 expression and the grade of dysplasia, as well as between the marker's staining patterns. Ten dysplastic nevi from six female patients were selected and their histological features (size, dysplasia), as well as the immunohistological staining patterns, were studied (HMB-45, Melan A, Bcl-2). The Pearson correlation coefficient and regression was calculated with Windows Excel Data Analysis. We demonstrated that there was a notable correlation between the dysplasia and the size of the lesions (r(8)= 0.62 with p-value= 0.052), and also between Melan A and Bcl-2 (a r(6)= 0.73, p0.05). We can affirm, at least in our cases, there is a correlation between the grade of dysplasia and the size of the lesion, and also, that there is a correlation between Melan A and Bcl-2 staining, explained by MITF gene. These results were only partial concordant with those in other studies, therefore a larger number of cases is recommended to be further analyzed in order to clearly draw a conclusion.

Background: Acetabular labral tears are highly associated with hip dysplasia. Magnetic resonance arthrography (MR arthrography) is the expensive and time-consuming contemporary gold-standard method in the radiological assessment of acetabular labral tears. Purpose: To assess the diagnostic ability of noninvasive ultrasound (US) examination compared to MR arthrography in diagnosing acetabular labral tears in dysplastic hip joints. Material and Methods: The study compared US examination and MR arthrography diagnosis of labral tears in 20 consecutively referred dysplastic hip joints. Results: The ability to diagnose acetabular labral tears upon US examination was calculated: sensitivity 44%, specificity 75%, positive predictive value 88%, and negative predictive value 25%. Conclusion: The ability of US examination in diagnosing acetabular labral tears is not yet good enough. The technique is still to be developed, and more experience, especially with the interpretation of US examinations, is needed.

Metastatic Basal Cell Carcinoma Accompanying Gorlin Syndrome

Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

The reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is uncertain and its assessment was the major aim of this study. The different peripheral blood and bone marrow variables required for an adequate morphological classification were blindly evaluated by four cytomorphologists in samples from 50 patients with myelodysplastic syndromes. The degree of agreement among observers was calculated using intraclass correlation coefficient and the generalized kappa statistic for multiple raters. The degree of agreement for the percentages of blasts in bone marrow and peripheral blood, ring sideroblasts in bone marrow, and erythroid, granulocytic and megakaryocytic dysplastic cells was strong (P<0.001 in all instances). After stratifying the percentages according to the categories required for the assignment of World Health Organization subtypes, the degree of agreement was not statistically significant for cases with 5-9% blasts in bone marrow (P=0.07), 0.1-1% blasts in peripheral blood (P=0.47), or percentage of erythroid dysplastic cells (P=0.49). Finally, the interobserver concordance for World Health Organization-defined subtypes showed a moderate overall agreement (P<0.001), the reproducibility being lower for cases with refractory anemia with excess of blasts type 1 (P=0.05) and refractory anemia with ring sideroblasts (P=0.09). In conclusion, the reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is acceptable but the defining criteria for blast cells and features of erythroid dysplasia need to be refined.

3-Amino-1,2,4-triazole Limits the Oxidative Damage in UVA-Irradiated Dysplastic Keratinocytes

Full Text Available Reactive oxygen species (ROS generated by UVA irradiation affect the keratinocyte cell membrane, DNA, and proteins and may cause serious injury to the skin. Treating human dysplastic keratinocytes (DOK with 3-amino-1,2,4-triazole (AMT, a common catalase inhibitor, induced a compensatory mechanism for the hydrogen peroxide detoxification, which included a rise in glutathione peroxidase and glutathione reductase activities. Here, we examined a possible role of AMT in protecting a human DOK cell line against UVA-induced damage. In DOK cells exposed to UVA irradiation, we observed a substantial decrease in antioxidant enzymatic activities, such as catalase, glutathione peroxidase, glutathione reductase, and glutathione-S-transferase and an increase in lipid peroxidation and protein oxidation levels. Treating DOK cells with AMT prior to UVA exposure enhanced the activities of glutathione peroxidase, glutathione reductase, and glutathione-S-transferase, relative to nontreated cells. The enhanced antioxidant activities were correlated with decreased protein oxidation levels. Based on these results, we suggest that AMT may protect dysplastic keratinocytes against the harmful effects of UVA radiation.

Michelin tire baby syndrome: a review of the literature and a proposal for diagnostic criteria with adoption of the name circumferential skin folds syndrome.

2014-01-01

The term Michelin tire baby (MTB), named for the cartoon mascot of the Michelin Tire Company, has been used to describe babies with multiple symmetric circumferential rings of folded skin. In those reported with this phenotype who had skin biopsies, pathology has shown nevus lipomatosis, smooth muscle hamartoma, degenerative collagen, and scarring. Others did not undergo biopsy or had normal skin. Many individuals with the MTB phenotype have had a variety of other congenital anomalies. I review the literature on MTB and the history of the designation Michelin tire baby Syndrome (MTBS). Because the term MTBS has been poorly defined or not defined at all, I propose strict criteria for diagnosis. In doing so, it is recommended that the syndrome be renamed to avoid further confusion. © 2014 Wiley Periodicals, Inc.

Variations of Ki-67, p53, and Adnab-9 monoclonal antibody reactions in colonic adenomas may be associated with colonic cancer risk. We studied the predictive value of these markers for adverse behavior in severely dysplastic colorectal adenomas, such as an associated carcinoma, multiplicity of adenomas, and subsequent development of adenomas. For this purpose we compared theclinical, gross, and histologic characteristics of highly dysplastic index polyps in 42 patients with Ki 67, p53, and Adnab-9 immunostaining and other molecular markers. Polyps were removed endoscopically, and severely dysplastic polyps were stained immunohistochemically with Ki-67, Adnab-9, and p53 protein by the avidin biotin conjugate (ABC) technique. Quantitative DNA (QDNA) was analyzed by computer-assisted image analysis. Ki-67 immunohistochemistry showed reversal of normal distribution of nuclear staining from the normal basal position to the upper third of the colonic crypts. This abnormality of immunostaining in dysplastic adenomas was the earliest detected by the panel we used. A statistically significant correlation was seen between invasiveness of carcinoma in the index polyp and polyp size (P = 0.003), sessile morphology (P = 0.037), and villous or tubulovillous histology (P = 0.019). In the index adenoma, p53 positivity was correlated with multiplicity at initial examination (P = 0.053), villous histology (P = 0.053), invasiveness of carcinoma (P < 0.003), and recurrence of colorectal adenomas (P = 0.025). Although p53 positivity and aneuploidy were correlated with invasiveness of carcinoma in the index polyp (P = 0.025), Adnab-9 positivity was not. However, Adnab-9 positivity in the index polyp was associated with multiplicity of adenomas (P = 0.04) as well as recurrence of adenomas (P < 0.024). In conclusion, in addition to the morphologic and histologic markers already known, Ki-67, Adnab-9 antibody, and p53 protein may be prognostic indicators useful in follow-up of patients

Halo congenital melanocytic nevus (CMN) associated with vitiligo is rare, especially with regard to CMN excision. Only two reports of excision of halo CMN following repigmentation of vitiligo are found in the literature. We present a case of a girl with halo CMN and periorbital vitiligo. The halo CMN was excised and followed by spontaneous improvement of vitiligo. The result suggests excision of the inciting lesion may be a promising way to control vitiligo. © 2015 Wiley Periodicals, Inc.

To demonstrate a combination laser therapy to treat Hori's nevus. A prospective study. A Singapore-based clinic. Five female patients, aged 30-46 years, with bilateral malar Hori's nevus. Photographs were taken before treatment and 1 month after laser treatment was completed. These were graded by three independent physicians. The patients were also asked to grade their treatment response subjectively. They were followed up for a total of 3 months after laser treatment to monitor recurrence. The fractional nonablative 2,940-nm Er:YAG laser with a fluence of 0.7 J/cm(2), spot size 12 mm, and frequency 15 Hz was used to perform a full-face single-pass treatment. Subsequently, a second pass and third pass over Hori's nevi were done bilaterally till the clinical endpoint of skin whitening. The 1,064-nm Q-switched (QS) Nd:YAG at a fluence of 2.0 J/cm(2), frequency 2 Hz, and 4-mm spot size was used to deliver multiple passes over Hori's nevus till erythema with mild petechiae appeared. We repeated the treatment once a week for 3 more consecutive weeks. All five patients had above 80% improvement in their pigmentation and two (skin type III) achieved complete 100% clearance. Based on the patients' subjective assessments, all five of them expressed satisfaction and felt that their pigmentation had improved. There were no complications noted. The fractional nonablative 2940 nm Er:YAG laser and Q-switched 1064nm laser Nd:YAG combination is an effective and safe treatment for Hori's nevus.

A case of dysplastic gangliocytoma of the cerebellum, or Lhermitte-Duclos disease, is reported along with its CT findings, and the cases so far reported in the literature are reviewed. This is the 50th case report since the first description in 1920. This 61-year-old female had suffered from right hemifacial spasms for more than 20 years and from bilateral tinnitus with auditory disturbances for two years. Four years before admission, she underwent gastric resection and cancer chemotherapy for gastric cancer. Plain craniograms showed a thinned and ballooned occipital squama on the right side. Vertebral angiograms revealed a large tumor stain, with early venous filling, in the right posterior fossa. A CT scan showed a large, low-density mass, with small calcified areas in it, in the right posterior fossa. A postcontrast CT scan revealed no contrast enhancement, except for dilated vascular enhancement, within the tumor. No hydrocephalus was observed. Metrizamide CT cisternography revealed a huge intraaxial mass compressing the brain stem. (J.P.N.)

RAS GTPases mediate a wide variety of cellular functions, including cell proliferation, survival, and differentiation. Recent studies have revealed that germline mutations and mosaicism for classical RAS mutations, including those in HRAS, KRAS, and NRAS, cause a wide spectrum of genetic disorders. These include Noonan syndrome and related disorders (RAS/mitogen-activated protein kinase [RAS/MAPK] pathway syndromes, or RASopathies), nevus sebaceous, and Schimmelpenning syndrome. In the present study, we identified a total of nine missense, nonsynonymous mutations in RIT1, encoding a member of the RAS subfamily, in 17 of 180 individuals (9%) with Noonan syndrome or a related condition but with no detectable mutations in known Noonan-related genes. Clinical manifestations in the RIT1-mutation-positive individuals are consistent with those of Noonan syndrome, which is characterized by distinctive facial features, short stature, and congenital heart defects. Seventy percent of mutation-positive individuals presented with hypertrophic cardiomyopathy; this frequency is high relative to the overall 20% incidence in individuals with Noonan syndrome. Luciferase assays in NIH 3T3 cells showed that five RIT1 alterations identified in children with Noonan syndrome enhanced ELK1 transactivation. The introduction of mRNAs of mutant RIT1 into 1-cell-stage zebrafish embryos was found to result in a significant increase of embryos with craniofacial abnormalities, incomplete looping, a hypoplastic chamber in the heart, and an elongated yolk sac. These results demonstrate that gain-of-function mutations in RIT1 cause Noonan syndrome and show a similar biological effect to mutations in other RASopathy-related genes.

Caveolin-1(Cav-1), the main part of caveolae structure, is supposed to play a role in pathogenesis of many human tumors. Since oral lichen planus (OLP) is considered as a potential premalignant disease, this study evaluated Cav-1 expression in OLP in comparison with benign hyperkeratosis, dysplastic epithelium and oral squamous cell carcinoma (OSCC), to investigate its possible role in pathogenesis and malignant transformation of OLP. In this cross-sectional retrospective study, immunohistochemical expression of Cav-1 in the epithelial component and stroma was evaluated in 81 samples, including 12 cases of hyperkeratosis, 24 OLP, 22 epithelial dysplasia, and 23 OSCC samples. Correlations between Cav-1 expression and clinicopathological variables were evaluated statistically. Positive Cav-1 staining was found in 58% of OLP, 91% of hyperkeratosis, 100% of epithelial dysplasia, and 95% of OSCC samples. OSCC showed the highest Cav-1 expression and OLP had the lowest (P=0.001). The intensity of staining was significantly increased in stepwise manner from OLP to OSCC (P=0.001). Expression of Cav-1 was related to the grade of samples in OSCC and dysplastic samples (P=0.04). Based on the findings, it was concluded that Cav-1 may play a role in the pathogenesis of OLP and carcinogenesis of SCC, but its role in malignant transformation of OLP is not confirmed. Further studies are needed to evaluate its potential therapeutic function in OLP and SCC. Copyright © 2017 Elsevier GmbH. All rights reserved.

2018-06-01

Full Text Available UVA radiation induces multiple and complex changes in the skin, affecting epidermal cell behavior. This study reports the effects of UVA exposure on normal (HaCaT and dysplastic (DOK keratinocytes. The adherence, spreading and proliferation were investigated by time-lapse measurement of cell layer impedance on different matrix proteins. Prior to UVA exposure, the time required for adherence and spreading did not differ significantly for HaCaT and DOK cells, while spreading areas were larger for HaCaT cells. Under UVA exposure, HaCaT and DOK cells behavior differed in terms of movement and proliferation. The cells’ ability to cover the denuded surface and individual cell trajectories were recorded by time-lapse videomicroscopy, during wound healing experiments. Dysplastic keratinocytes showed more sensitivity to UVA, exhibiting transient deficiencies in directionality of movement and a delay in re-coating the denuded area. The actin cytoskeleton displayed a cortical organization immediately after irradiation, in both cell lines, similar to mock-irradiated cells. Post-irradiation, DOK cells displayed a better organization of stress fibers, persistent filopodia, and new, stronger focal contacts. In conclusion, after UVA exposure HaCaT and DOK cells showed a different behavior in terms of adherence, spreading, motility, proliferation, and actin cytoskeleton dynamics, with the dyplastic keratinocytes being more sensitive.

Full Text Available Background The elliptical excision is the standard method of removing benign skin lesions,such as congenital melanocytic nevi. This technique allows for primary closure, with little to nodog-ear deformity, but may sacrifice normal tissue adjacent to the lesion, resulting in scarswhich are unnecessarily long. This study was designed to compare the predicted results ofelliptical excision with those resulting from our excision technique.Methods Eighty-two patients with congenital melanocytic nevus on the face were prospectivelystudied. Each lesion was examined and an optimal ellipse was designed and marked onthe skin. After an incision on one side of the nevus margin, subcutaneous undermining wasperformed in the appropriate direction. The skin flap was pulled up and approximated alongseveral vectors to minimize the occurrence of dog-ear deformity.Results Overall, the final wound length was 21.1% shorter than that achieved by ellipticalexcision. Only 8.5% of the patients required dog-ear repair. There was no significant distortionof critical facial structures. All of the scars were deemed aesthetically acceptable based ontheir Patient and Observer Scar Assessment Scale scores.Conclusions When compared to elliptical excision, our technique appears to minimize dogeardeformity and decrease the final wound length. This technique should be considered analternative method for excision of facial nevi.

Identification of early presenting signs of the Basal Cell Nevus (BCNS; synonyme Gorlin-Goltz) syndrome, which is associated with a principal triad of multiple basal cell nevi, jaw odontogenic keratocysts, and skeletal anomalies, in stomatological and neurological practices. Proposal of multidisciplinary diagnostic algorithm comprising other medical specialists, including pathology, imaging, laboratory and molecular analyses based on the study outcomes. Case report of a male patient reporting paresthesia of their lower jaw, with right facial asymmetry (maxilla and mandible) and radiological detection of large osteolytic lesions in both jaws, including a retrospective analysis of a representative Czech cohort with BCNS from within the last decade. Clinical, imaging and laboratory analyses were carried out at a national tertiary centre. A multidisciplinary clinical approach followed by surgical management lead to the identification of odontogenic cysts, which were substantiated by histological examination. DNA sequencing of the PTCH1 gene detected a c.2929dupT resulting in p. Tyr977Leufs*16 pathogenic variant. This finding confirmed the clinical and laboraoty diagnosis of BCNS. Parental DNA analysis showed that this causal genetic defect arose de novo. Surgical management and orthodontic therapy were successful. Analysis of the reported case and retrospective data analysis provided evidence that paresthesia of the lower jaw should be considered as one of the early presenting signs of this rare disorder in stomatological and neurological practice. Obtained results allowed us to formulate recommendations for diagnostic practice in stomatology and neurology.

Full Text Available Objective: To demonstrate a combination laser therapy to treat Hori′s nevus. Design: A prospective study. Setting: A Singapore-based clinic. Participants: Five female patients, aged 30-46 years, with bilateral malar Hori′s nevus. Measurements: Photographs were taken before treatment and 1 month after laser treatment was completed. These were graded by three independent physicians. The patients were also asked to grade their treatment response subjectively. They were followed up for a total of 3 months after laser treatment to monitor recurrence. Materials and Methods: The fractional nonablative 2,940-nm Er:YAG laser with a fluence of 0.7 J/cm 2, spot size 12 mm, and frequency 15 Hz was used to perform a full-face single-pass treatment. Subsequently, a second pass and third pass over Hori′s nevi were done bilaterally till the clinical endpoint of skin whitening. The 1,064-nm Q-switched (QS Nd:YAG at a fluence of 2.0 J/cm 2 , frequency 2 Hz, and 4-mm spot size was used to deliver multiple passes over Hori′s nevus till erythema with mild petechiae appeared. We repeated the treatment once a week for 3 more consecutive weeks. Results: All five patients had above 80% improvement in their pigmentation and two (skin type III achieved complete 100% clearance. Based on the patients′ subjective assessments, all five of them expressed satisfaction and felt that their pigmentation had improved. There were no complications noted. Conclusion: The fractional nonablative 2940 nm Er:YAG laser and Q-switched 1064nm laser Nd:YAG combination is an effective and safe treatment for Hori′s nevus.

Oral squamous cell carcinoma is the most common malignant lesion of the oral cavity, and it involves various molecular mechanisms. The development of oral squamous cell carcinoma is influenced by the host immune cells, such as eosinophils. The present study was conducted to compare the presence of eosinophils in normal mucosa, dysplastic mucosa, and oral squamous cell carcinoma by -hematoxylin- eosin staining, Congo red staining, and epidermal growth factor-like (EGF-like) module containing a mucin-like hormone receptor1 (EMR1) immunohistochemical marker. In this cross-sectional study, 60 paraffinized samples were selected, consisting of 20 normal mucosae, 20 dysplastic mucosae, and 20 squamous cell carcinoma samples. After confirmation of the diagnosis, the mean number of eosinophils was evaluated by hematoxylin-eosin, Congo red, and immunohystochemical staining techniques. The data were analyzed by SPSS-10 software using the Kruskal-Wallis and Friedman tests. The results showed that the number of eosinophils in dysplastic mucosa was significantly higher than the number in normal mucosa, and the number of eosinophils in squamous cell carcinoma was significantly higher than the number in dysplastic mucosa in all staining techniques (p<0.001). Moreover, the comparison of staining techniques showed a significantly higher number of eosinophils in EMR1immunohistochemicalmarker than were observed when Congo red and hematoxylin - eosin (H&E) staining techniques were used (p<0.001). It can be argued that eosinophil contributes to the identification of lesions that have a higher potential of malignant transformation. Moreover, eosinophil can be suggested as an indicator in the differentiation of oral lesions in cases with borderline diagnosis and in targeted molecular therapy.

The aim of the study was a retrospective evaluation of our patients with post-dysplastic hips treated by cemented or non-cemented total hip arthroplasty (THA) in order to ascertain which type and position of the acetabular component was most effective. In the years 1999-2002, 111 THA procedures were performed in 93 patients, 76 women and 17 men, with post-dysplastic hip arthritis. The average age of the patients at the time of implantation was 52.6 years. On the basis of pre-operative radiographic findings, the patients' conditions were evaluated using the Hartofilakidis classification into three disease categories: dysplasia, low dislocation and high dislocation, and the patients were placed in two groups. Group 1 included 78 patients, and group 2 comprised 26 patients. None of our patients was classified as having high dislocation. Thirty-nine of these patients had previously undergone surgery for dysplastic hips. A total of 104 THAs were evaluated, because radiographic data was incomplete in seven cases. In addition to X-ray findings, the prosthesis type (cemented, hybrid, non-cemented), post-operative complications and signs of loosening were included in the evaluation. Clinical outcomes were assessed by the Harris score. The follow-up terminating on 31st December 2005 was 67 months on the average. In group 1 patients, the average Harris score increased from 38.6 to 80.3 points and in group 2 patients from 35.5 to 84.9 points, mostly with excellent and good results. In 72.1 % of the hips, a press-fit acetabular component was implanted. In 55.8 % of the cases, the acetabular component was implanted off the anatomical center of rotation, into the high hip center, with the range from 9 to 20 mm and an average of 15 mm. The average limb lengthening was 2.5 cm, ranging from 1.0 to 3.5 cm. Our results show that it is more effective to use non-cemented THA for post-dysplastic hips. The implantation of a noncemented acetabular component into the high center provides

Whole cell extracts from human lymphoid cell lines can perform in vitro DNA repair synthesis in plasmids damaged by agents including UV or cis-diamminedichloroplatinum(II) (cis-DDP). Extracts from xeroderma pigmentosum (XP) cells are defective in repair synthesis. We have now studied in vitro DNA repair synthesis using extracts from lymphoblastoid cell lines representing four human hereditary syndromes with increased sensitivity to DNA-damaging agents. Extracts of cell lines from individuals with the sunlight-sensitive disorders dysplastic nevus syndrome or Cockayne's syndrome (complementation groups A and B) showed normal DNA repair synthesis in plasmids with UV photoproducts. This is consistent with in vivo measurements of the overall DNA repair capacity in such cell lines. A number of extracts were prepared from two cell lines representing the variant form of XP (XP-V). Half of the extracts prepared showed normal levels of in vitro DNA repair synthesis in plasmids containing UV lesions, but the remainder of the extracts from the same cell lines showed deficient repair synthesis, suggesting the possibility of an unusually labile excision repair protein in XP-V. Fanconi's anemia (FA) cells show cellular hypersensitivity to cross-linking agents including cis-DDP. Extracts from cell lines belonging to two different complementation groups of FA showed normal DNA repair synthesis in plasmids containing cis-DDP or UV adducts. Thus, there does not appear to be an overall excision repair defect in FA, but the data do not exclude a defect in the repair of interstrand DNA cross-links

Full Text Available Traditional Chinese medicine (TCM syndrome is an important basis for TCM diagnosis and treatment. As Child-Pugh classification as well as compensation and decompensation phase in liver cirrhosis, it is also an underlying clinical classification. In this paper, we investigated the correlation between single nucleotide polymorphisms (SNPs of Interleukin-10 (IL-10 and TCM syndromes in patients with hepatitis B cirrhosis (HBC. Samples were obtained from 343 HBC patients in China. Three SNPs of IL-10 (−592A/C, −819C/T, and −1082A/G were detected with polymerase chain-reaction-ligase detection reaction (PCR-LDR. The result showed the SNP-819C/T was significantly correlated with Deficiency syndrome (P=0.031, but none of the 3 loci showed correlation either with Child-Pugh classification and phase in HBC patients. The logistic regression analysis showed that the Excess syndrome was associated with dizzy and spider nevus, and the Deficiency syndrome was associated with dry eyes, aversion to cold, IL-10-819C/T loci, and IL-10-1082A/G loci. The odds ratio (OR value at IL-10-819C/T was 4.022. The research results suggested that IL-10-819C/T locus (TC plus CC genotype is probably a risk factor in the occurrence of Deficiency syndrome in HBC patients.

Full Text Available Macrophages have long been recognized as a prominent component of tumors. Activated macrophages overexpress folate receptors and we used this phenomenon to image inflammatory reactions in colon dysplasia using a fluorescent folate probe (FFP. APCΔ468 mice injected with FFP showed fluorescent adenomas (target-to-background ratio, adenoma vs. adjacent normal mucosa, of 2.46 ± 0.41, significantly higher (p < .001 than adenomas in animals injected with a non-folate-containing control probe. Fluorescence-activated cell-sorting analysis revealed a 3-fold higher content of Mac1-positive cells in colonic adenomas compared with normal adjacent mucosa (6.8% vs. 2.2%, and confirmed the source of FFP-positive cells to be primarily an F4/80-positive macrophage subpopulation. Taken together, these results indicate that FFP potentially can be used to image dysplastic intestinal adenomas in vivo.

Lynch syndrome is caused by germline mutations of DNA mismatch repair (MMR) genes. MMR deficiency has long been regarded as a secondary event in the pathogenesis of Lynch syndrome colorectal cancers. Recently, this concept has been challenged by the discovery of MMR-deficient crypt foci in the normal mucosa. We aimed to reconstruct colorectal carcinogenesis in Lynch syndrome by collecting molecular and histology evidence from Lynch syndrome adenomas and carcinomas. We determined the frequency of MMR deficiency in adenomas from Lynch syndrome mutation carriers by immunohistochemistry and by systematic literature analysis. To trace back the pathways of pathogenesis, histological growth patterns and mutational signatures were analyzed in Lynch syndrome colorectal cancers. Literature and immunohistochemistry analysis demonstrated MMR deficiency in 491 (76.7%) out of 640 adenomas (95% CI: 73.3% to 79.8%) from Lynch syndrome mutation carriers. Histologically normal MMR-deficient crypts were found directly adjacent to dysplastic adenoma tissue, proving their role as tumor precursors in Lynch syndrome. Accordingly, mutation signature analysis in Lynch colorectal cancers revealed that KRAS and APC mutations commonly occur after the onset of MMR deficiency. Tumors lacking evidence of polypous growth frequently presented with CTNNB1 and TP53 mutations. Our findings demonstrate that Lynch syndrome colorectal cancers can develop through three pathways, with MMR deficiency commonly representing an early and possibly initiating event. This underlines that targeting MMR-deficient cells by chemoprevention or vaccines against MMR deficiency-induced frameshift peptide neoantigens holds promise for tumor prevention in Lynch syndrome. © 2018 UICC.

Linear psoriasis is a rare form of the disease characterized by the linear distribution of lesions involving dermatome or along Blaschko's lines. Clinically, it may resemble inflammatory linear verrucous epidermal nevus; a combination of history, skin examination, and histopathology are required to ensure correct diagnosis and appropriate therapy. This paper describes a case of a 23-year-old male presenting with unilateral erythematous scaly plaques arranged in a linear path on the left leg. Etanercept was initiated after poor response to adalimumab. Improvement of his psoriasis was noted, with PASI 75 reduction after 24 weeks of treatment. Clinical studies have shown excellent efficacy of etanercept, and our patient well tolerated treatment with etanercept for 52 weeks without any adverse effects.

The mechanical stiffness of individual cells is important in tissue homeostasis, cell growth, division and motility, and the epithelial–mesenchymal transition in the initiation of cancer. In this work, a normal squamous cell line (EPC2) and metaplastic (CP-A) as well as dysplastic (CP-D) Barrett's Esophagus columnar cell lines are studied as a model of pre-neoplastic progression in the human esophagus. We used the combination of an atomic force microscope (AFM) with a scanning confocal fluorescence lifetime imaging microscope to study the mechanical properties of single adherent cells. Sixty four force indentation curves were taken over the nucleus of each cell in an 8 × 8 grid pattern. Analyzing the force indentation curves, indentation depth-dependent Young's moduli were found for all cell lines. Stiffness tomograms demonstrate distinct differences between the mechanical properties of the studied cell lines. Comparing the stiffness for indentation forces of 1 nN, most probable Young's moduli were calculated to 4.7 kPa for EPC2 (n = 18 cells), 3.1 kPa for CP-A (n = 10) and 2.6 kPa for CP-D (n = 19). We also tested the influence of nuclei and nucleoli staining organic dyes on the mechanical properties of the cells. For stained EPC2 cells (n = 5), significant stiffening was found (9.9 kPa), while CP-A cells (n = 5) showed no clear trend (2.9 kPa) and a slight softening was observed (2.1 kPa) in the case of CP-D cells (n = 16). Some force–indentation curves show non-monotonic discontinuities with segments of negative slope, resembling a sawtooth pattern. We found the incidence of these 'breakthrough events' to be highest in the dysplastic CP-D cells, intermediate in the metaplastic CP-A cells and lowest in the normal EPC2 cells. This observation suggests that the microscopic explanation for the increased compliance of cancerous and pre-cancerous cells may lie in their susceptibility to 'crumble and yield' rather than their

Epigenetic inactivation of tumor-related genes is an important characteristic in the pathology of human cancers, including melanomagenesis. We analyzed the epigenetic inactivation of Claudin 11 (CLDN11) in malignant melanoma (MM) of the skin, including six melanoma cell lines, 39 primary melanoma, 41 metastases of MM and 52 nevus cell nevi (NCN). CLDN11 promoter hypermethylation was found in 19 out of 39 (49%) of the primary MM and in 21 out of 41 (51%) of the MM metastases, but only in eight out of 52 (15%) of NCN (p = 0.001 and p = 0.0003, respectively). Moreover, a significant increase in the methylation level of CLDN11 from primary melanomas to MM metastases was revealed (p = 0.003). Methylation of CLDN11 was significantly more frequent in skin metastases (79%) compared to brain metastases (31%; p = 0.007). CLDN11 methylation was also found in five out of six MM cell lines (83%) and its promoter hypermethylation correlated with a reduced expression. Treatment of MM cell lines with a DNA methylation inhibitor reactivated CLDN11 transcription by its promoter demethylation. In summary, CLDN11 proved to be an epigenetically inactivated tumor related gene in melanomagenesis, and analysis of CLDN11 methylation level represents a potential tool for assisting in the discrimination between malignant melanoma and nevus cell nevi.

Full Text Available Congenital giant megaureter presents as abdominal mass and impose diagnostic difficulties. It can be associated with other upper urinary tract anomalies. A female newborn with antenatal diagnosis of polycystic kidneys was admitted at birth due to lower abdominal mass. Ultrasound and CT scans diagnosed a multiloculated cystic lesion in the mid and lower abdomen along with right side multicystic kidney. At laparotomy, an extaperitoneal, lobulated cystic swelling was found due to rightside giant megaureter. Its lower end was of normal caliber and orthotopic. End cutaneous ureterostomy was done. Intravenous urogram and isotope renograms showed nonfunctioning right kidney. She also had grade II vesicoureteral reflux on left side. Child suffered urinary infection twice. At 9m age, right nephroureterectomy was done. Histopathologic examination was consistent with cystic renal dysplasia and dilated ureter. This is the first case report of giant megaureter associated with ipsilateral multicystic dysplastic kidney in newborn.

Full Text Available Abstract Ellis-van Creveld syndrome (EVC is a chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. The exact prevalence is unknown, but the syndrome seems more common among the Amish community. Prenatal abnormalities (that may be detected by ultrasound examination include narrow thorax, shortening of long bones, hexadactyly and cardiac defects. After birth, cardinal features are short stature, short ribs, polydactyly, and dysplastic fingernails and teeth. Heart defects, especially abnormalities of atrial septation, occur in about 60% of cases. Cognitive and motor development is normal. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. EVC belongs to the short rib-polydactyly group (SRP and these SRPs, especially type III (Verma-Naumoff syndrome, are discussed in the prenatal differential diagnosis. Postnatally, the essential differential diagnoses include Jeune dystrophy, McKusick-Kaufman syndrome and Weyers syndrome. The management of EVC is multidisciplinary. Management during the neonatal period is mostly symptomatic, involving treatment of the respiratory distress due to narrow chest and heart failure. Orthopedic follow-up is required to manage the bones deformities. Professional dental care should be considered for management of the oral manifestations. Prognosis is linked to the respiratory difficulties in the first months of life due to thoracic narrowness and possible heart defects. Prognosis of the final body height is difficult to predict.

Thirteen newborns with lethal short rib-polydactyly (SRP) have been reviewed, 11 with SRP type 3 (Verma-Naumoff) and 2 with SRP tye 2 (Majewski). In the former group there were three sets of siblings. The excess of males with SRP type III (Verma-Naumoff) is confirmed in this present study. A high frequency of phenotypic females including sex-reversed constitutional males with SRP type 1 (Saldino-Noonan) is in marked contrast to these findings in SRP type 3. Possible hypotheses include variable expressivity in non-Majewski short rib-polydactyly syndromes with sex-reversed and constitutional female cases tending to show more severe phenotypic expression both in terms of major anomalies and skeletal dysplastic effects.

Full Text Available BACKGROUND Neurocutaneous disorders are genetically determined disorders showing both cutaneous and neurologic involvement. The definition includes both hereditary and non-hereditary phenotypes, but excludes acquired disorders. Either they follow the established Mendelian modes of inheritance or they represent lethal mutations surviving by mosaicism or they belong to the group of chromosomal disorders. MATERIALS AND METHODS This study was conducted at the Department of Dermatology, Government KAPV Medical College, Trichy, for a period of 12 months from January 2016 to December 2016. Patients were selected among those attending the outpatient department with signs and symptoms pertaining to neurocutaneous syndromes. Preliminary information like age, sex, educational qualification, present and past illness, family history elicited. Dermatological examination consisted of thorough screening of patients to detect the cutaneous markers for neurocutaneous disorders. A detailed systemic examination was done, particularly central nervous system. RESULTS In this study, neurofibromatosis (68.8% topped the list followed by tuberous sclerosis complex (18.3% and other rarer disorders like xeroderma pigmentosum (2.7%, giant congenital melanocytic naevus (1.8%, Sturge-Weber syndrome (0.9%, Waardenburg syndrome (1.8%, epidermal naevus syndrome (1.8%, naevus comedonicus (0.9%, Elejalde syndrome (0.9%, oculocutaneous albinism (0.9% and Adams-Oliver syndrome (0.9%. CONCLUSION In this study of 109 cases of neurocutaneous syndromes, neurofibromatosis topped the list followed by tuberous sclerosis complex. Classical features of xeroderma pigmentosum was observed in 1 patient. Sturge-Weber syndrome with unilateral port wine stain with seizures was reported in our study. Two cases of Waardenburg syndrome, epidermal nevus syndrome and giant congenital melanocytic nevus were reported in my study. One case of unilateral nevus comedonicus, Elejalde syndrome, oculocutaneous

Globalisation, scientific and technical progress are the basis of numerous innovative therapies for oncologic and non-oncologic diseases. It is another matter how much and by whom they are desired, and whether they have to be applied. When and how often? Innovative approaches should go towards simplification, universal distribution and application while at the same time analysis between the potential initial investment and the achieved final result should be made. An illustrative example for this is the targeted therapy for melanoma with its low baseline criteria or basic rules for its surgical treatment. Another example could be the confocal microscopy in the context of dysplastic nevus syndrome. Therapies for various autoimmune diseases should also be considered critically. In the current OAMJMS issue, as well as in some of our other ideas and statements reported also in OAMJMS, we are trying to answer at least to a part of these dilemmas, to provoke a critical point of view and to ask some simple questions: "Should any innovation be considered as a face value? Which is potentially beneficial for our patients? How could we regulate the processes to minimise the need for expensive medications for certain diseases? And, of course, we are also turning to our own mistakes by visualising the results of them!

We report a case of bilateral congenital midureteric strictures diagnosed using MR urography. The severity of obstruction differed in the two ureters, resulting in a multicystic dysplastic kidney (MCDK) with an atretic ureter on one side and hydronephrosis that worsened over time due to progressive stenosis on the other. Although midureteric strictures are usually misdiagnosed as ureteropelvic junction (UPJ) or ureterovesical junction (UVJ) obstruction on conventional imaging, MR urography was able to clearly demonstrate both the anatomical and functional abnormalities. Additionally, because of the excellent anatomical resolution, similarities in the underlying pathological lesions could be contrasted with the severity of the pathophysiological impact upon each kidney.

Two dogs with severe dysplastic pulmonary valve stenosis and right-to-left shunting defects (patent foramen ovale, perimembranous ventricular septal defect) underwent palliative stenting of the right ventricular outflow tract and pulmonary valve annulus using balloon expandable stents. One dog received 2 over-lapping bare metal stents placed 7 months apart; the other received a single covered stent. Both procedures were considered technically successful with a reduction in the transpulmonary valve pressure gradient from 202 to 90 mmHg in 1 dog and from 168 to 95 mmHg in the other. Clinical signs of exercise intolerance and syncope were temporarily resolved in both dogs. However, progressive right ventricular concentric hypertrophy, recurrent stenosis, and erythrocytosis were observed over the subsequent 6 months leading to poor long-term outcomes. Stenting of the right ventricular outflow tract is feasible in dogs with severe dysplastic pulmonary valve stenosis, though further study and optimization of the procedure is required.

Chromosome 3 amplification affecting the 3q26 region is a common genomic alteration in cervical cancer, typically marking the transition of precancerous intraepithelial lesions to an invasive phenotype. Though potential 3q encoded target genes of this amplification have been identified, a functional correlation of potential oncogenic function is still missing. In this study, we investigated copy number changes and the expression level of SEC62 encoded at 3q26.2 as a new potential 3q oncogene in dysplastic cervical lesions and analyzed its role in cervical cancer cell biology. Expression levels of Sec62 and vimentin were analyzed in liquid based cytology specimens from 107 women with varying grades of cervical dysplasia ranging from normal cases to cancer by immunofluorescence cytology. Additionally, a subset of 20 representative cases was used for FISH analyses targeting SEC62. To further explore the functional role of Sec62 in cervical cancer, HeLa cells were transfected with a SEC62 plasmid or SEC62 siRNA and analyzed for their proliferation and migration potential using real-time monitoring and trans-well systems as well as changes in the expression of EMT markers. FISH analyses of the swabbed cells showed a rising number of SEC62 gains and amplifications correlating to the grade of dysplasia with the highest incidence in high grade squamous intraepithelial lesions and squamous cell carcinomas. When analyzing the expression level of Sec62 and vimentin, we found a gradually increasing expression level of both proteins according to the severity of the dysplasia. In functional analyses, SEC62 silencing inhibited and SEC62 overexpression stimulated the migration of HeLa cells with only marginal effects on cell proliferation, the expression level of EMT markers and the cytoskeleton structure. Our study suggests SEC62 as a target gene of 3q26 amplification and a stimulator of cellular migration in dysplastic cervical lesions. Hence, SEC62 could serve as a potential

In 1947 the term phakomatosis pigmentovascularis (PPV) was coined to represent the association of widespread, aberrant, and persistent nevus flammeus and pigmentary abnormalities. Four types of PPV have been recognized with type II (nevus flammeus and Mongolian spots) being the most common. Most early cases were of Asian or African descent. Many cases were subsequently associated with Sturge-Weber (S-W) and Klippel-Trenaunay (K-T) syndromes. Almost no literature reports have appeared in the genetic or dysmorphology literature! We present six cases of PPV in which five were either African, Asian or Hispanic, and five of six had an admixture of K-T and S-W. Four had macrocephaly, and one had microcephaly. Four had CNS abnormalities (three with hydrocephalus, one with Arnold-Chiari and one with polymicrogyria), three had mental retardation, and one had seizures. One each had thumb hypoplasia, hydronephrosis, glaucoma, coronal synostosis, and 3-4 finger syndactyly. It is our suspicion and hypothesis that in the presence of persistent, extensive and aberrant Mongolian spots, vascular abnormalities as are seen in K-T and S-W carry a worse prognosis. This may be particularly true either of children of Asian, Hispanic or African heritage or any individuals from darker pigmented skin groups. (c) 2007 Wiley-Liss, Inc.

Kaufman oculo-cerebro-facial syndrome (KOS) is caused by recessive UBE3B mutations and presents with microcephaly, ocular abnormalities, distinctive facial morphology, low cholesterol levels and intellectual disability. We describe a child with microcephaly, brachycephaly, hearing loss, ptosis, blepharophimosis, hypertelorism, cleft palate, multiple renal cysts, absent nails, small or absent terminal phalanges, absent speech and intellectual disability. Syndromes that were initially considered include DOORS syndrome, Coffin-Siris syndrome and Dubowitz syndrome. Clinical investigations coupled with karyotype analysis, array-comparative genomic hybridization, exome and Sanger sequencing were performed to characterize the condition in this child. Sanger sequencing was negative for the DOORS syndrome gene TBC1D24 but exome sequencing identified a homozygous deletion in UBE3B (NM_183415:c.3139_3141del, p.1047_1047del) located within the terminal portion of the HECT domain. This finding coupled with the presence of characteristic features such as brachycephaly, ptosis, blepharophimosis, hypertelorism, short palpebral fissures, cleft palate and developmental delay allowed us to make a diagnosis of KOS. In conclusion, our findings highlight the importance of considering KOS as a differential diagnosis for patients under evaluation for DOORS syndrome and expand the phenotype of KOS to include small or absent terminal phalanges, nails, and the presence of hallux varus and multicystic dysplastic kidneys.

We report the case of a 19-year-old man who presented with a 12-year history of progressive fatigue, feeling hot, excessive sweating, and numbness in the left arm. He had undergone multimodal imaging and was diagnosed as having Klippel-Trénaunay-Weber syndrome (KTWS). This is a rare congenital disease, defined by combinations of nevus flammeus, venous and lymphatic malformation, and hypertrophy of the affected limbs. Lower extremities are affected mostly. Conventional modalities for evaluating KTWS are ultrasonography, CT, MRI, lymphoscintigraphy, and angiography. There are few reports on multimodal imaging of upper extremities of KTWS patients, and this is the first report of an infrared thermography in KTWS.

A case of dysplastic gangliocytoma of the cerebellum, or Lhermitte-Duclos disease, is reported along with its CT findings, and the cases so far reported in the literature are reviewed. This is the 50th case report since the first description in 1920. This 61-year-old female had suffered from right hemifacial spasms for more than 20 years and from bilateral tinnitus with auditory disturbances for two years. Four years before admission, she underwent gastric resection and cancer chemotherapy for gastric cancer. Plain craniograms showed a thinned and ballooned occipital squama on the right side. Vertebral angiograms revealed a large tumor stain, with early venous filling, in the right posterior fossa. A CT scan showed a large, low-density mass, with small calcified areas in it, in the right posterior fossa. A postcontrast CT scan revealed no contrast enhancement, except for dilated vascular enhancement, within the tumor. No hydrocephalus was observed. Metrizamide CT cisternography revealed a huge intraaxial mass compressing the brain stem. (J.P.N.).

Purpose: Retrospective analysis of the dilatation (PTRA) of renal arterial dysplastic stenosis (RADS). Methods: Seventy patients suffering from hypertension (87RADS) were treated at our institution for medial (83%) or non-classified fibrodysplasias (17%). Four patients suffered from renal insufficiency. Two endoprostheses were implanted. We evaluated blood pressure with the USCSRH criteria and renal insufficiency with the Martin criteria. Results: Ninety-five percent technical success and 87.9% clinical success for blood pressure were obtained, with worse results for patients older than 57 years or with a history of hypertension greater than 9 years. Results were better when the RADS was responsible for an ipsilateral renal atrophy or for poorly controlled hypertension. No renal insufficiency worsened during the follow-up. Conclusion: PTRA is a first-line treatment for renovascular hypertension caused by RADS. The results were encouraging despite a high average age of the subjects and frequent associated extrarenal vascular lesions

Differential diagnosis of high-grade dysplastic nodules (HGDN) and well-differentiated hepatocellular carcinoma (WDHCC) represents a challenge to experienced hepatic clinicians, radiologists and hepatopathologists. The expression profiles of aminoacylase-1 (ACY1), sequestosome-1 (SQSTM1) and glypican-3 (GPC3) in low-grade dysplastic nodules (LGDN), HGDN and WDHCC were assessed by immunohistochemistry. The differential diagnostic performances of these three markers alone and in combination for HGDN and WDHCC were investigated by logistic regression models (HGDN = 21; WDHCC = 32) and validated in an independent test set (HGDN, n = 21; WDHCC n = 24). Postoperative overall survival and time to recurrence were evaluated by univariate and multivariate analyses in an independent set of 500 patients. ACY1, SQSTM1 and GPC3 were differentially expressed in each group. For the differential diagnosis of WDHCC from HGDN, the sensitivity and specificity of the combination of ACY1 + SQSTM1 + GPC3 for detecting WDHCC were 93.8% and 95.2% respectively in the training set, which were higher than any of the three two-marker combinations. The validities of the four diagnostic models were further confirmed in an independent test set, and corresponding good sensitivity and specificity were observed. Interestingly, GPC3 expression in HCC tissues combined with serum α-fetoprotein (AFP) was found to be an independent predictor for overall survival and time to recurrence. ACY1 + SQSTM1 + GPC3 combination represents a potentially valuable biomarker for distinguishing between WDHCC and HGDN using immunohistochemistry. Meanwhile, low GPC3 staining combined with positive serum AFP may play a practical role in predicting poor postoperative outcome and high tumor recurrence risk

BIOMECHANICS OF THERAPEUTIC RIDING DURING THE DISEASES OF I-II DEGREE DYSPLASTIC LUMBAR AND STATIC (SHORT LEG) SCOLIOSIS.

The goal of the paper is to substantiate the essence of ridetherapy biomechanics as the pathogenetic therapeutic and prophylactic method at lumbar dysplastic (the I and II degrees) and static (short-legged induced) scoliosis. Uneven lower extremities caused by any reason and asymmetric support induce the change in the arrangement of trochantin to the vertebra and correspondingly the uneven loading of lumbar muscles. The asymmetric strength of lumbar muscles evoked by the change in rotator condition becomes the cause of the formation of scoliosis primary arc which, in its turn, causes a compensatory spinal curvature. In case of dysplastic scoliosis a leading role belongs to the beginning of dystrophic changes in intervertebral discs and its further decentration. At riding position the lower extremities are completely disengaged from the antigravity redistribution, the child is in direct contact with vibrations and jolts coming from the horseback; the antigravity loading is distributed on the muscles of the torso and thus, it creates an opportunity to purposefully affect the correction of the spine. During scoliosis the pathogenic essence of ridetherapy is due to the comprehensiveness of its procedures, expressed in the fact that during one procedure several factors are influenced simultaneously: nucleus pulpous, the torso and iliopsoas muscles, the antigravity system, etc. According to the clinical-functional and radiographic studies carried out in the dynamics on 11-16 years old adolescents it has been established that in those groups where the rehabilitation was conducted in a complex with ridetherapy the authentically higher results were obtained as compared to the groups where the rehabilitation was held using therapeutic exercises and massage.

Deletion 22q13.3 syndrome

Full Text Available Abstract The deletion 22q13.3 syndrome (deletion 22q13 syndrome or Phelan-McDermid syndrome is a chromosome microdeletion syndrome characterized by neonatal hypotonia, global developmental delay, normal to accelerated growth, absent to severely delayed speech, and minor dysmorphic features. The deletion occurs with equal frequency in males and females and has been reported in mosaic and non-mosaic forms. Due to lack of clinical recognition and often insufficient laboratory testing, the syndrome is under-diagnosed and its true incidence remains unknown. Common physical traits include long eye lashes, large or unusual ears, relatively large hands, dysplastic toenails, full brow, dolicocephaly, full cheeks, bulbous nose, and pointed chin. Behavior is autistic-like with decreased perception of pain and habitual chewing or mouthing. The loss of 22q13.3 can result from simple deletion, translocation, ring chromosome formation and less common structural changes affecting the long arm of chromosome 22, specifically the region containing the SHANK3 gene. The diagnosis of deletion 22q13 syndrome should be considered in all cases of hypotonia of unknown etiology and in individuals with absent speech. Although the deletion can sometimes be detected by high resolution chromosome analysis, fluorescence in situ hybridization (FISH or array comparative genomic hybridization (CGH is recommended for confirmation. Differential diagnosis includes syndromes associated with hypotonia, developmental delay, speech delay and/or autistic-like affect (Prader-Willi, Angelman, Williams, Smith-Magenis, Fragile X, Sotos, FG, trichorhinophalangeal and velocardiofacial syndromes, autism spectrum disorders, cerebral palsy. Genetic counseling is recommended and parental laboratory studies should be considered to identify cryptic rearrangements and detect parental mosaicism. Prenatal diagnosis should be offered for future pregnancies in those families with inherited rearrangements

Exome analysis has had a dramatic impact on genetic research. We present the application of such newly generated information to patient care. The patient was a female, born with normal growth parameters to nonconsanguineous parents after an uneventful pregnancy. She had bilateral cleft lip/palate and ankyloblepharon. Sparse hair, dysplastic nails and hypohidrosis were subsequently noted. With exception of speech related issues, her development was normal. A clinical diagnosis of ankyloblepharon-ectodermal defects-cleft lip/palate or Hay-Wells syndrome resulted in TP63 sequence analysis. TP63 sequence and deletion/duplication analysis of all coding exons had a normal result, as did chromosome and SNP array analysis. Diagnostic exome analysis revealed a heterozygous nonsense mutation in KRT83 categorized as deleterious and associated with monilethrix. In addition, a homozygous missense variant of unknown clinical significance was reported in RIPK4. Using research based exome analysis, RIPK4 had just a few months prior been identified as pathogenic for Bartsocas-Papas syndrome. While the clinical diagnostic report implied the KRT83 mutation as a more likely cause for the patient's phenotype, clinical correlation, literature review and use of computerized mutation analysis programs allowed us to identify the homozygous RIPK4 (c.488G > A; p.Gly163Asp) mutation as the underlying pathogenic change. Consequently, we expand the phenotype of Bartsocas-Papas syndrome to an attenuated presentation resembling Hay-Wells syndrome, lacking lethality and pterygia. In contrast to the autosomal dominant Hay-Wells syndrome, Bartsocas-Papas syndrome is autosomal recessive, implying a 25% recurrence risk. Copyright © 2013 Wiley Periodicals, Inc.

The common origin from neural crest cell (NCC of facial structures (cartilagineous, osseous, vascular and of the peripheral nervous system and of peripheral glia and partially of the CNS white matter are underlined and the facial and glial abnormalities are attributed to the abnormal reproduction/migration of NCC. In this view, the CNS spongy alterations in KSS may be not only a dystrophic process (leukodystrophy but also a dysplastic condition (leukodysplasia. The Authors hypothesize that the symptoms may be related to mtDNA mutations associated to NCC nuclear gene abnormality. SOX 10 gene may be a nuclear candidate gene, as reported in some case of Waardenburg IV syndrome.

Fibroblastic connective tissue nevus: a rare cutaneous lesion analyzed in a series of 25 cases.

Fibroblastic connective tissue nevus (FCTN) represents a rare and distinct benign cutaneous mesenchymal lesion of fibroblastic/myofibroblastic lineage, which broadens the spectrum of lesions presently recognized as connective tissue nevus. A series of 25 cases of FCTN has been analyzed to further characterize the clinicopathologic spectrum and immunohistochemical features of this entity. Sixteen patients were female (64%) and 9 were male (36%), with age at presentation ranging from 1.5 months to 58 years (median, 10 y). Most patients presented with a solitary, slowly growing, painless plaque-like or nodular skin lesion. Eleven cases (44%) arose on the trunk, 9 (36%) on the head and neck, and 5 (20%) on the limbs. The lesion was present for a median duration of 11.5 months (mean, 13.2 mo). Grossly, the lesions were tan-brown to tan-white, smooth, and firm. Their size ranged from 0.3 to 2.0 cm in greatest dimension (mean size, 0.67 cm; median, 0.6 cm). All tumors showed poor circumscription and were situated primarily in the reticular deep dermis, extending into the superficial subcutis in 13 cases (52%). The lesion was associated with papillomatous epidermis in 17 cases (70%) and the presence of adipose tissue in the reticular dermis in 14 cases (60.9%). All tumors were composed of a proliferation of bland intradermal fibroblastic/myofibroblastic cells with indistinct palely eosinophilic cytoplasm and tapering nuclei, with no significant cytologic atypia or pleomorphism, arranged in short-intersecting fascicles and entrapping appendages. No mitoses were identified. Immunostains showed positivity for CD34 in 20 of 23 cases (87%) and weak focal positivity for smooth muscle actin in 9 of 19 cases (47%). No case stained positively for desmin or S100 protein. Clinical follow-up was obtained for 14 patients (median duration, 4 y). No tumor recurred locally, even when surgical excision was incomplete. No lesion metastasized. FCTN occurs most commonly as a plaque on the

Full Text Available Development of multiple basal cell carcinomas is commonly associated with immunosuppression or genetic disorders. The latter include congenital diseases such as Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome. It is an autosomal dominant inherited disorder characterized by the development of multiple basal cell carcinomas at an early age and a variable combination of other phenotypic abnormalities that result in multiple organ involvement. The susceptibility gene was mapped to chromosome 9q22.3-3.1. Like other tumor suppressor genes, PTCH1 gene shows frequent deletion and a whole variety of other mutations. A high rate of new mutations and the variable expressivity of the condition make full diagnostic assessment difficult, especially in mildly affected individuals with no family history of the condition. It has been postulated that the presence of two major features or one major feature with two minor features classify a condition as Gorlin-Goltz syndrome.

heterogeneous clinical and laboratorial presentations, which result in progressive bone marrow failure and evolve to acute leukemia. Anemia is a common symptom. In elderly patients, it is not attributed to the normal aging process and the cause is identified in most cases. The presence of cytopenias associated with bone marrow dysplastic disorders may also be due to secondary and reversible non clonal disorders. Cytogenetic abnormalities found in a proportion of patients with myelodysplastic syndromes may be helpful in the differential diagnosis and to evaluate the prognosis. Ancillary laboratory tests to show clonality are not usually available. The diagnosis of myelodysplastic syndromes is, therefore, made by exclusion, sometimes helped by the passage of time. Considering the proposed multistep myelodysplastic syndrome pathogenesis, patients at the lowest grade, presenting minimal dysplastic features may be difficult to diagnose. Vitamin B12 and/or folate deficiency, recent exposure to heavy metals and recent cytotoxic or growth factor therapy should be considered absolute exclusion factors precluding the definite diagnosis. Alcohol use, chronic inflammatory states, auto-immune disorders, chronic liver or kidney diseases, hormonal disorders and viral infections including HIV must be ruled out or interpreted with caution. Some diseases of the pluripotential stem cells must also be distinguished from myelodysplastic syndromes. Exclusion of paroxysmal nocturnal hemoglobinuria and aplastic anemia may be difficult in the less common hypocellular myelodysplastic syndromes. Dysplastic abnormalities of the bone marrow, therefore, do not in themselves establish a diagnosis of myelodysplasia and a protocol of exclusion should be carried out.

Here, time of flight secondary ion mass spectrometry (ToF-SIMS) and multivariate analysis were combined to study the role of ulcerative colitis (UC), a type of inflammatory bowel disease (IBD), in the colon cancer progression. ToF-SIMS was used to obtain mass spectra and chemical maps from the mucosal surface of human normal (NC), inflamed (IC), and dysplastic (DC) colon tissues. Chemical mapping with a lateral resolution of ≈ 1 μm allowed to evaluate zonation of fatty acids and amino acids as well as the morphological condition of the intestinal glands. High mass resolution ToF-SIMS spectra showed chemical differences in lipid and amino acid composition as a function of pathological state. In positive ion mode, mono- (MAG), di- (DAG), and triacylglycerol (TAG) signals were detected in NC tissues, while in IC and DC tissues, the only cholesterol was present as lipid class representative. Signals from fatty acids, collected in negative ion mode, were subjected to principal component analysis (PCA). PCA showed a strict correlation between IC and DC samples, due to an increase of stearic, arachidonic, and linoleic acid. In the same way, differences in the amino acid composition were highlighted through multivariate analysis. PCA revealed that glutamic acid, leucine/isoleucine, and valine fragments are related to IC tissues. On the other hand, tyrosine, methionine, and tryptophan peaks contributed highly to the separation of DC tissues. Finally, a classification of NC, IC, and DC patients was also achieved through hierarchical cluster analysis of amino acid fragments. In this case, human colonic inflammation showed a stronger relationship with normal than dysplastic condition. Graphical Abstract ᅟ.

2016-01-01

Backgrounds: Lichen planus is a chronic systemic disease and oral mucosa is commonly involved. Oral lichen planus (OLP) most commonly affects middle-aged women. The prevalence of the disease ranges between 0.5% and 2.6% in the general population and the range of malignant transformation varies between 0% and 10%. Objectives: To assess the rate of malignant transformation of OLP samples. Materials and Methods: This retrospective study was carried out on 112 medical records of patients with histological diagnosis of OLP who attended the Department of Pathology at the Educational Hospital from 2005 to 2012. H&E-stained slides were reviewed by two pathologists using strict clinical and histopathological diagnostic World Health Organization (WHO) criteria. Dysplastic changes were diagnosed and graded according to the latest WHO classification. Results: Of the 112 cases diagnosed as OLP, there were 39 males and 73 females and the patients’ ages ranged from 15 to 86 years (mean age 44.5 years). The erosive form with fifty cases was the most common clinical type and the papular type with one case was the least common clinical type. Regarding the site, the buccal mucosa was the most common site with 52 cases. Totally, dysplastic changes were found in 12 samples, among them five cases showed mild dysplasia and seven cases showed moderate dysplasia. One case developed oral squamous cell carcinoma after 3 years. Conclusion: OLP is considered as a premalignant condition by the WHO and several authors. Although the malignancy rate is not so high, to reduce morbidity and mortality from cancer arising on OLP lesions, a regular follow-up examination is recommended. PMID:27721603

Barrett's esophagus is a condition in which the normal squamous lining of the esophagus has been replaced by columnar epithelium containing intestinal metaplasia induced by recurrent mucosal injury related to gastroesophageal reflux disease. Barrett's esophagus is a premalignant condition that can progress through a dysplasia-carcinoma sequence to esophageal adenocarcinoma. Multiple endoscopic ablative techniques have been developed with the goal of eradicating Barrett's esophagus and preventing neoplastic progression to esophageal adenocarcinoma. For patients with high-grade dysplasia or intramucosal neoplasia, radiofrequency ablation with or without endoscopic resection for visible lesions is currently the most effective and safe treatment available. Recent data demonstrate that, in patients with Barrett's esophagus and low-grade dysplasia confirmed by a second pathologist, ablative therapy results in a statistically significant reduction in progression to high-grade dysplasia and esophageal adenocarcinoma. Treatment of dysplastic Barrett's esophagus with radiofrequency ablation results in complete eradication of both dysplasia and of intestinal metaplasia in a high proportion of patients with a low incidence of adverse events. A high proportion of treated patients maintain the neosquamous epithelium after successful treatment without recurrence of intestinal metaplasia. Following successful endoscopic treatment, endoscopic surveillance should be continued to detect any recurrent intestinal metaplasia and/or dysplasia. This paper reviews all relevant publications on the endoscopic management of Barrett's esophagus using radiofrequency ablation. PMID:28070182

We present herein a series of 14 lesions showing overlapping features with the newly defined benign cutaneous mesenchymal neoplasm labeled as fibroblastic connective tissue nevus (FCTN). Total of 8 patients were male and 5 were female, ranging in age from 1 to 56 years. Lesions appeared as isolated nodules or plaques on the trunk (7 cases), the limbs (4 cases) and the neck (2 cases). Histologically, all cases were composed of bundles of bland spindle cells of fibroblastic/myofibroblastic lineage irregularly branching within the reticular dermis and along fibrous septa in the subcutis. Adnexal structures and dermal adipocytes were entrapped by the fascicles, the epidermis was often papillomatous and elastic fibers were decreased and fragmented. Expression of CD34 and ASMA was found in 8 and 7 cases, respectively. Follow-up was available for 7 patients (mean follow-up, 5 years; range, 1-10 years). None of the cases metastasized or recurred, even when incompletely excised. The differential diagnosis of FCTN is broad and includes hypertrophic scar, dermatofibroma, dermatomyofibroma, pilar leiomyoma, plaque-stage DFSP, CD34-positive plaque-like dermal fibroma, fibroblastic-predominant plexiform fibrohistiocytic tumor, lipofibromatosis, superficial desmoid fibromatosis and fibrous hamartoma of infancy, of which it represents probably the monophasic variant. © 2017 John Wiley & Sons A/S.

Induzem facilmente ao erro diagnóstico, apesar de nenhuma transformação maligna ter sido descrita. Relatamos o desenvolvimento de um nevo melanocítico adquirido grande no local de bolhas recorrentes em uma criança de 5 anos portadora de Epidermólise bolhosa simples. O padrão dermatoscópico global foi sugestivo de benignidade, e os achados histopatológicos foram compatíveis com um nevo melanocítico composto. Este é o primeiro caso de um Nevo da Epidermólise bolhosa publicado na literatura brasileiraAcquired melanocytic lesions resembling malignant melanoma have been described in all major categories of Epidermolysis bullosa and referred to as "Epidermolysis bullosa nevi''. They easily induce to diagnostic error, although no malignant transformation has been reported. We report the development of a large acquired melanocytic nevus at a site of recurrent blisters in a 5-year-old child with Epidermolysis bullosa simplex. The global dermoscopic pattern was suggestive of benignity, and the histopathological findings were compatible with a compound melanocytic nevus. This is the first published case of Epidermolysis bullosa nevi in Brazilian literature. Despite their benign behavior, we emphasize the importance of regular clinical and dermoscopic monitoring, since a malignant course still cannot be totally excluded

Meckel-Gruber Syndrome: Autopsy Based Approach to Diagnosis

Asaranti Kar

2016-01-01

Full Text Available Meckel-Gruber syndrome (MGS is a rare lethal congenital malformation affecting 1 in 13,250-140,000 live births. The classical diagnostic triad comprises multicystic dysplastic kidneys, occipital encephalocele, and postaxial polydactyly. It can variably be associated with other malformations such as cleft lip and palate, pulmonary hypoplasia, hepatic fibrosis, and anomalies of central nervous system. A 20 weeks fetus was diagnosed as MGS with classical features along with many other congenital abnormalities such as microcephaly, microphthalmia, hypertelorism, cleft lip and palate, neonatal teeth, and the right side club foot which were detected only after doing autopsy. This case is reported because of its rarity emphasizing the importance of neonatal autopsy in every case of fetal death, especially where the antenatal diagnosis has not been made previously. A systematic approach to accurate diagnosis of MGS based on autopsy will be described here which can allow recurrence risk counseling and proper management in future pregnancies.

Full Text Available OBJECTIVE To determine the frequency and types of craniofacial abnormalities observed in patients with trisomy 18 or Edwards syndrome (ES. METHODS This descriptive and retrospective study of a case series included all patients diagnosed with ES in a Clinical Genetics Service of a reference hospital in Southern Brazil from 1975 to 2008. The results of the karyotypic analysis, along with clinical data, were collected from medical records. RESULTS: The sample consisted of 50 patients, of which 66% were female. The median age at first evaluation was 14 days. Regarding the karyotypes, full trisomy of chromosome 18 was the main alteration (90%. Mosaicism was observed in 10%. The main craniofacial abnormalities were: microretrognathia (76%, abnormalities of the ear helix/dysplastic ears (70%, prominent occiput (52%, posteriorly rotated (46% and low set ears (44%, and short palpebral fissures/blepharophimosis (46%. Other uncommon - but relevant - abnormalities included: microtia (18%, orofacial clefts (12%, preauricular tags (10%, facial palsy (4%, encephalocele (4%, absence of external auditory canal (2% and asymmetric face (2%. One patient had an initial suspicion of oculo-auriculo-vertebral spectrum (OAVS or Goldenhar syndrome. CONCLUSIONS: Despite the literature description of a characteristic clinical presentation for ES, craniofacial alterations may be variable among these patients. The OAVS findings in this sample are noteworthy. The association of ES with OAVS has been reported once in the literature.

On the interplay of telomeres, nevi and the risk of melanoma.

Directory of Open Access Journals (Sweden)

Clara Bodelon

Full Text Available The relationship between telomeres, nevi and melanoma is complex. Shorter telomeres have been found to be associated with many cancers and with number of nevi, a known risk factor for melanoma. However, shorter telomeres have also been found to decrease melanoma risk. We performed a systematic analysis of telomere-related genes and tagSNPs within these genes, in relation to the risk of melanoma, dysplastic nevi, and nevus count combining data from four studies conducted in Italy. In addition, we examined whether telomere length measured in peripheral blood leukocytes is related to the risk of melanoma, dysplastic nevi, number of nevi, or telomere-related SNPs. A total of 796 cases and 770 controls were genotyped for 517 SNPs in 39 telomere-related genes genotyped with a custom-made array. Replication of the top SNPs was conducted in two American populations consisting of 488 subjects from 53 melanoma-prone families and 1,086 cases and 1,024 controls from a case-control study. We estimated odds ratios for associations with SNPs and combined SNP P-values to compute gene region-specific, functional group-specific, and overall P-value using an adaptive rank-truncated product algorithm. In the Mediterranean population, we found suggestive evidence that RECQL4, a gene involved in genome stability, RTEL1, a gene regulating telomere elongation, and TERF2, a gene implicated in the protection of telomeres, were associated with melanoma, the presence of dysplastic nevi and number of nevi, respectively. However, these associations were not found in the American samples, suggesting variable melanoma susceptibility for these genes across populations or chance findings in our discovery sample. Larger studies across different populations are necessary to clarify these associations.

Sturge-Weber syndrome (SWS) is a non-hereditary congenital disorder due to somatic mosaic mutations in the GNAQ gene. The classical presentation relates to the brain lesion (cerebral angiomatous lesion of leptomeninges, which is responsible for epileptic seizures, hemiparesis and mental retardation), skin lesion (unilateral facial nevus), ocular and oral involvement. We present a 12-year-old boy who was referred to the Division of Pediatric Neurology, King Saud University Medical City, Riyadh, Saudi Arabia with left-sided hemiparesis. Physical examination showed a port wine stain involving the right side of the face, extending to the upper thorax, and enlargement of both the right eye globe and cornea (megalocornea), indicating the presence of glaucoma. Following urgent referral to ophthalmology service, his eye condition improved dramatically post surgery. Neuroradiological investigations, including cranial computed tomography (CT) and magnetic resonance angiography (MRI) revealed the classical brain lesions of SWS, as well as right leptomeningeal choroidal angioma. Ten months later, he developed focal-onset seizures which responded to treatment. His cognition is normal with good school performance. Continued vigilance is needed to identify and manage the complications of SWS.

The clinical distinction between basal cell carcinoma (BCC) and intradermal melanocytic nevus lesions on the face can be difficult, particularly in young patients or patients with multiple nevi. Dermoscopy is a useful tool for analyzing characteristic dermoscopic features of BCC, such as cartwheel structures, maple leaf-like areas, blue-gray nests and dots, and ulceration. It also reveals arborizing telangiectatic vessels and prominent curved vessels, which are typical of BCC, and comma vessels, which are typical of intradermal melanocytic nevi. It is, however, not always easy to distinguish between these 2 conditions, even when dermoscopy is used. We describe 2 facial lesions that posed a clinical and dermoscopic challenge in two 38-year-old patients; confocal microscopy showed separation between tumor nests and stroma and polarized nuclei, which are confocal microscopy features of basal cell carcinoma.

Cornelia de Lange syndrome is a rare genetic disease characterized by distinctive facial dysmorphia and dwarfism. Multiple organ system involvement is typical. Various central nervous system (CNS) aberrations have been described in the pathology literature; however, the spectrum of neuroimaging manifestations is less well documented. To present neuroimaging findings from a series of eight patients with Cornelia de Lange syndrome. The CT/MR database at a single academic children's hospital was searched for the terms ''Cornelia'', ''Brachmann'' and ''de Lange.'' The search yielded 18 exams from 16 patients. Two non-CNS and six exams without available images were excluded. Ten exams from eight patients were evaluated by a board-certified neuroradiologist. All patients had skull base dysplasia, most with an unusual coronal basioccipital cleft (7/8). All brain MR exams showed microcephaly, volume loss and gyral simplification (5/5). Six patients had an absent massa intermedia. Four patients had small globe anterior segments; three had optic pathway hypoplasia. Basilar artery fenestration was present in two patients; vertebrobasilar hypoplasia was present in one patient. The inner ear vestibules were dysplastic in two patients. One patient had pachymeningeal thickening. Spinal anomalies included scoliosis, segmentation anomalies, endplate irregularities, basilar invagination, foramen magnum stenosis and tethered spinal cord. Typical imaging manifestations of Cornelia de Lange syndrome include skull base dysplasia with coronal clival cleft, cerebral and brainstem volume loss, and gyral simplification. Membranous labyrinth dysplasia, anterior segment and optic pathway hypoplasia, basilar artery fenestration, absent massa intermedia and spinal anomalies may also be present. (orig.)

Treacher Collins syndrome (TCS, OMIM 154500) is a well-defined mandibulofacial dysostosis characterized by symmetric facial anomalies consisting of malar hypoplasia, coloboma of the lower eyelid, dysplastic ears, micrognathia, cleft palate and deafness. Other mandibulofacial dysostoses (MDs) such as Toriello (OMIM 301950), Bauru (OMIM 604830), Hedera-Toriello-Petty (OMIM 608257), and Guion-Almeida (OMIM 610536) syndromes are less well characterized and much rarer. Here we describe three unrelated patients showing clinical features overlapping with TCS, but who in addition have developmental delay, microcephaly and a distinct facial gestalt. Because of the distinct ear anomalies and the hearing loss a HOXA2 mutation was taken into account. CHARGE syndrome was discussed because of ear anomalies, choanal atresia, and developmental delay in our patients. But mutational analyses including sequencing of the TCOF1, the HOXA2, and the CHD7 genes, deletion screening of the TCOF1 gene as well as genomewide array analyses revealed normal results. We suggest that these three patients have a new type of mandibulofacial dysostosis. As all three cases are sporadic and both sexes are affected the pattern of inheritance might be autosomal dominant or autosomal recessive. Identification of additional patients will allow to further delineate the phenotype, to assign the inheritance pattern and to identify the molecular basis.

The cardinal feature of myelodysplastic syndromes (MDS) is dysplasia involving one or more myeloid cell lineages. In the present study, we used 4-color flow cytometric analysis to investigate dysgranulopoiesis in bone marrow specimens from 65 patients with MDS. The antigen expression patterns of total neutrophil granulocytes (TNG) and of the two distinct neutrophil granulocytic subpopulations (NGSs), NGS-1 (dimmer CD45 expression) and NGS-2 (stronger CD45 expression) identified on the side scatter (SS) vs. CD45-intensity plot, were studied. The neutrophil granulocytes from patients with MDS showed characteristic antigen expression aberrancies which were more pronounced in NGS-2 subpopulation. Studying separately the NGS-2 subpopulation with the CD16/MPO/LF combination, the low CD16(+)/MPO(+) and low CD16(+)/LF(+) percentages seemed to discriminate between lower-risk and higher-risk patients with MDS in most occasions. Furthermore, a detailed assessment of the NGS-1 and NGS-2 immunophenotypic patterns revealed early dysplastic changes, not otherwise observed by standard TNG analysis, especially in cases of lower-risk MDS.

2017-01-01

Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Reports on PPBS do not highlight the radiological and imaging characteristics of this syndrome and the current literature on the role of newer imaging modalities, such as Magnetic Resonance Imaging (MRI), remains relatively sparse. We describe a new case of PPBS and emphasize the role of imaging, especially ultrasound and MRI in the process of diagnosis and briefly review the subject. A male infant of four months of age was referred for evaluation of left-sided cryptorchidism. Clinical examination revealed laxity of the left abdominal wall. Ultrasound examination of the abdomen, pelvis and scrotum was performed together with routine laboratory tests. Ultrasound examination was followed by intravenous urography, voiding cysto-urethrography and MRI of the abdomen. On ultrasound, the left testis was located in the inguinal canal, the right kidney was slightly enlarged and the left kidney could not be localized. Ultrasound appearances suggested chronic obstruction in the urinary bladder. Intravenous urography, voiding cysto-urethrography and MRI confirmed the ultrasound diagnosis and also revealed a left dysplastic kidney with a dilated, tortuous ureter. Clinical and imaging features were consistent with pseudo prune belly syndrome (PPBS). We report a new occurrence of PPBS, a rare entity. The imaging approach for a comprehensive evaluation of the renal system in PPBS, especially with MRI, is emphasized.

To assess the inter-observer and intra-observer reliability of two commonly used radiographic classification systems in the evaluation of hip dysplasia in skeletally mature adults. Three observers with different levels of training independently classified 62 dysplastic hips on 51 standard anteriorposterior pelvis radiographs according to the criteria defined by Crowe and by Hartofilakidis. To assess intra-observer reliability, the same radiographs were reviewed 3 months later by the same observers. At the time of the radiographic examination, the mean age of the 51 patients had been 54 years (range 18-82 years). A high correlation concerning the inter- and intra-observer reliability of both systems was demonstrated. Inter-observer reliability displayed a weighted kappa coefficient of 0.82 for the Crowe and 0.75 for the Hartofilakidis classification. Intra-observer reliability showed a kappa coefficient of 0.86 and 0.79, respectively. Both classification systems can be recommended to compare collectives of adult patients with congenital dysplasia of the hip. However, for future clinical practice, it would be advisable to agree on one universally accepted system as a standard in the literature. (orig.)

To assess the inter-observer and intra-observer reliability of two commonly used radiographic classification systems in the evaluation of hip dysplasia in skeletally mature adults. Three observers with different levels of training independently classified 62 dysplastic hips on 51 standard anteriorposterior pelvis radiographs according to the criteria defined by Crowe and by Hartofilakidis. To assess intra-observer reliability, the same radiographs were reviewed 3 months later by the same observers. At the time of the radiographic examination, the mean age of the 51 patients had been 54 years (range 18-82 years). A high correlation concerning the inter- and intra-observer reliability of both systems was demonstrated. Inter-observer reliability displayed a weighted kappa coefficient of 0.82 for the Crowe and 0.75 for the Hartofilakidis classification. Intra-observer reliability showed a kappa coefficient of 0.86 and 0.79, respectively. Both classification systems can be recommended to compare collectives of adult patients with congenital dysplasia of the hip.

Should elderly patients with higher-risk myelodysplastic syndromes undergo allogeneic hematopoietic stem cell transplantation?

Science.gov (United States)

Zeidan, Amer M; Gore, Steven D

2013-10-01

Myelodysplastic syndromes (MDS) include a group of hematopoietic malignancies characterized by dysplastic changes, ineffective hematopoiesis and variable risk of leukemic progression. At diagnosis, 86% of MDS patients are ≥60 years. Azacitidine, the only drug that prolongs life in high-risk (HR)-MDS patients, adds a median of only 9.5 months to life. Allogeneic stem cell transplantation (alloSCT) remains the only potentially curative approach. Despite recent improvements including use of reduced intensity conditioning (RIC) that decrease transplant-related mortality, alloSCT continues to be used rarely in elderly MDS. There is paucity of data regarding outcomes of RIC alloSCT in elderly MDS patients, especially in direct comparison with azanucleosides. In this paper, the authors discuss the recent Markov decision analysis by Koreth et al. in which investigators demonstrated superior survival of patients with HR-MDS aged 60-70 years who underwent RIC alloSCT in comparison with those who were treated with azanucleosides.

Summary Background Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Reports on PPBS do not highlight the radiological and imaging characteristics of this syndrome and the current literature on the role of newer imaging modalities, such as Magnetic Resonance Imaging (MRI), remains relatively sparse. We describe a new case of PPBS and emphasize the role of imaging, especially ultrasound and MRI in the process of diagnosis and briefly review the subject. Case Report A male infant of four months of age was referred for evaluation of left-sided cryptorchidism. Clinical examination revealed laxity of the left abdominal wall. Ultrasound examination of the abdomen, pelvis and scrotum was performed together with routine laboratory tests. Ultrasound examination was followed by intravenous urography, voiding cysto-urethrography and MRI of the abdomen. On ultrasound, the left testis was located in the inguinal canal, the right kidney was slightly enlarged and the left kidney could not be localized. Ultrasound appearances suggested chronic obstruction in the urinary bladder. Intravenous urography, voiding cysto-urethrography and MRI confirmed the ultrasound diagnosis and also revealed a left dysplastic kidney with a dilated, tortuous ureter. Clinical and imaging features were consistent with pseudo prune belly syndrome (PPBS). Conclusions We report a new occurrence of PPBS, a rare entity. The imaging approach for a comprehensive evaluation of the renal system in PPBS, especially with MRI, is emphasized. PMID:28580040

Williams syndrome (WS) is a complex genomic disorder entailing distinctive facial dysmorphism, cardiovascular abnormalities, intellectual disabilities, unusual behavioral features, and a specific cognitive profile with considerable variability. Additional symptoms include endocrine abnormalities, renal anomalies and connective tissue disorders. We report a monozygotic twin patient with WS who presented with multicystic kidneys in the newborn period, and, in addition to the typical WS deletion at 7q11.23, was found to have a de novo 1.7 Mb deletion in the 17q12 region on microarray comparative genomic hybridization. The co-twin was selectively terminated at 23 wk of gestation after being diagnosed with bilateral multicystic dysplastic kidneys and anhydramnios. Review of the literature shows that deletion of chromosome 17q12, encompassing hepatocyte nuclear factor 1beta gene, is associated with cystic renal disease and is the first recurrent genomic deletion associated with maturity onset diabetes of the young. In addition, reports of female reproductive tract malformations and patients with neurocognitive or psychiatric phenotypes have recently been described. This review of the literature summarizes 47 other cases involving 17q12 deletions with wide variability in phenotype, possibly suggesting a contiguous gene syndrome. It is likely that the additional 17q12 deletion has played a role in modifying the phenotype in our patient. This case highlights the importance of using array comparative genomic hybridization in the clinical setting to uncover the etiology of atypical findings in individuals with known microdeletion syndromes.

Continuous wave electron paramagnetic resonance (CW EPR) and X-band (9 GHz) EPR imaging (EPRI) were used to nondestructively investigate the possible differentiation between malignant melanoma (MM) and nevus pigmentosus (NP) melanin radicals in paraffin-embedded specimens. The EPR spectra of both samples were analyzed using linewidth, spectral pattern, and X-band EPRI. The CW-EPR spectra of the MM showed an additional signal overlap. Eumelanin- and pheomelanin-related radicals were observed in the MM specimens. The EPR results revealed that the peak-to-peak linewidths (ΔH pp ) of paraffin-embedded MM and NP samples were 0.65 ± 0.01 and 0.69 ± 0.01 mT, respectively. The g-value was 2.005 for both samples. Moreover, the two-dimensional (2D) EPRI of the MM showed different signal intensities at the different tumor stages, unlike the NP, which displayed fewer variations in signal intensity. Thus, the present results suggest that EPR and 2D EPRI can be useful for characterization of the two melanin radicals in the MM and for determination of their size and concentration.

Recently, pathogenic variants in the MLL2 gene were identified as the most common cause of Kabuki (Niikawa-Kuroki) syndrome (MIM#147920). To further elucidate the genotype-phenotype correlation, we studied a large cohort of 86 clinically defined patients with Kabuki syndrome (KS) for mutations in MLL2. All patients were assessed using a standardized phenotype list and all were scored using a newly developed clinical score list for KS (MLL2-Kabuki score 0-10). Sequencing of the full coding region and intron-exon boundaries of MLL2 identified a total of 45 likely pathogenic mutations (52%): 31 nonsense, 10 missense and four splice-site mutations, 34 of which were novel. In five additional patients, novel, i.e. non-dbSNP132 variants of clinically unknown relevance, were identified. Patients with likely pathogenic nonsense or missense MLL2 mutations were usually more severely affected (median 'MLL2-Kabuki score' of 6) as compared to the patients without MLL2 mutations (median 'MLL2-Kabuki score' of 5), a significant difference (p < 0.0014). Several typical facial features such as large dysplastic ears, arched eyebrows with sparse lateral third, blue sclerae, a flat nasal tip with a broad nasal root, and a thin upper and a full lower lip were observed more often in mutation positive patients. © 2013 John Wiley & Sons A/S.

Myxoid liposarcoma exhibits a peculiar clinical behavior, with a tendency to spread to serosal membranes, distant soft tissues, and bones, even in the absence of lung metastases. Therapy-related hematological neoplasms are well-known side effects of cytotoxic chemotherapy. We describe an exceptional case of metastatic myxoid liposarcoma of the spine associated with therapy-related refractory anemia with excess of blasts in a 37-year-old woman who underwent multi-agent chemotherapy for a myxoid liposarcoma of the left thigh. Microscopic examination of the bone marrow biopsy revealed dysplastic features, with abnormal localization of immature precursors and micromegakaryocytes, and islands of undifferentiated oval small/medium-size cells, suggestive of acute myeloid leukemia arising in the setting of a myelodysplastic syndrome. Immunohistochemistry was not discriminant. Cytogenetic analyses of bone marrow aspirate disclosed the presence of 2 different rearrangements, subsequently confirmed by fluorescent in situ hybridization and was crucial in making the correct diagnosis.

2017-01-01

Full Text Available Background: Thrombocytopenia may be encountered in various hematological and nonhematological conditions and may be associated with dysplastic megakaryocytes which is a feature of myelodysplastic syndrome (MDS, even though they can be observed in non-MDS hematological conditions. Objective: To study the morphological variations of megakaryocytes on bone marrow aspiration smears in non-MDS-related thrombocytopenia in a Medical College in Bengaluru, Karnataka. Materials and Methods: It was a prospective study of 86 cases of non-MDS thrombocytopenia whose bone marrow aspirates were studied morphologically. Results: The most common cause of thrombocytopenia was acute leukemia followed by other systemic malignancies, megaloblastic anemia, and idiopathic thrombocytopenic purpura. Both dysplastic and nondysplastic features were observed in the above-mentioned conditions. The most common dysplastic feature was nuclear segmentation followed by micromegakaryocytes and hypogranular forms. Among nondysplastic features, the most common were immature forms, bare nuclei, and hypolobation. Emperipolesis and cytoplasmic vacuoles were noted in a case of pyrexia of unknown origin. Conclusion: Dysplastic megakaryocytes are common in non-MDS-related thrombocytopenia and their mere presence should not lead to the diagnosis of MDS. Hence, proper diagnosis should be made on megakaryocyte morphology, patient's clinical findings, and other hematological parameters. This understanding can improve the diagnostic accuracy for wide range of hematological disorders.

Giant Congenital Melanocytic Nevus (GCMN - A New Hope for Targeted Therapy?

Directory of Open Access Journals (Sweden)

2017-07-01

Full Text Available We present a 6-month-old male patient, who was consulted with dermatologist by his parents, because of a pigmented lesion, present since birth, covering almost the all skin of the back and buttocks.  A sharply bordered, unequally coloured congenital pigmented nevus, measuring approximately 21 cm in diameter was observed in the whole body skin examination. The lesion was affecting the lower 2/3 of the skin of the back and the top half of the gluteus area, extending to the lateral part of the tors, forward the abdomen and the upper lateral part of the hips, composed by multiple darker-pigmented nests and several lighter areas, with single depigmented zones, hairy surface, irregularly infiltrated on palpation. Congenital melanocytic nevi are presented in approximately 1% of newborns, while giant congenital melanocytic nevi (GCMN are the most uncommon subtype of them; with occurrence rate 1 in 50,000 births. They affect 2% of a total body surface or presenting in a diameter larger than 20 cm in older children. Although not common, the possible malignant transformation remains one of the most important considerations related to them, as the related lifetime risk of melanoma is 4% to 10%. Treatment recommendations include non-surgical methods as dermabrasion only within the first two weeks of life, for prevention the possible melanocytic deeper migration, while serial surgical excisions or tissue expanders could be useful treatment tool even in later stages. Nevertheless, cosmetic result is not always satisfactory, and the risk of malignant changes remains, in cases of previous melanocytic migration in deeper layer. Recent article suggests the potential role in the treatment of GCMN with NRAS inhibitor trametinib, approved for treatment of advanced melanoma, associated with underlying NRAS mutations. Although promising, the drug could be useful in paediatric patients, only with associated NRAS gene mutation. It is still unclear whether it could be

Dysplastic Ichthyosis Uteri-like changes of the entire endometrium associated with a squamous cell carcinoma of the uterine cervix

Full Text Available Abstract Ichthyosis uteri is an exceedingly rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium. Originally described as an endometrial response to iatrogenically-introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium. We describe herein a heretofore undescribed example of a moderately differentiated squamous cell carcinoma of the uterine cervix associated with extensive ichthyosis uteri-like changes of the entire adjacent endometrium. Additionally, the squamous epithelium of the latter also showed multifocal changes diagnostic of a low-grade squamous intraepithelial lesion. The potential genesis of this composite of findings is discussed, as is the neoplastic potential of ichthyosis uteri. It is concluded that a squamous cell carcinoma of the cervix extended proximally into the endometrium, and that there was a colonization of a pre-existing ichthyosis uteri by associated human papillomavirus. The possibility of significant cervical pathology should be considered when plaques of squamous epithelium with low grade dysplastic changes are identified in an endometrial biopsy or curettage.

Neuropilins are receptors for disparate ligands, including proangiogenic factors such as vascular endothelial growth factor and inhibitory class 3 semaphorin (SEMA3) family members. Differentiated cells in skin epithelium and cutaneous squamous cell carcinoma highly express the neuropilin-1 (NRP1) receptor. We examined the expression of NRP1 in human and mouse oral mucosa. NRP1 was significantly up-regulated in oral epithelial dysplasia and oral squamous cell carcinoma (OSCC). NRP1 receptor localized to the outer suprabasal epithelial layers in normal tongue, an expression pattern similar to the normal skin epidermis. However, dysplastic tongue epithelium and OSCC up-regulated NRP1 in basal and proliferating epithelial layers, a profile unseen in cutaneous squamous cell carcinoma. NRP1 up-regulation is observed in a mouse carcinogen-induced OSCC model and in human tongue OSCC biopsies. Human OSCC cell lines express NRP1 protein in vitro and in mouse tongue xenografts. Sites of capillary infiltration into orthotopic OSCC tumors correlate with high NRP1 expression. HSC3 xenografts, which express the highest NRP1 levels of the cell lines examined, showed massive intratumoral lymphangiogenesis. SEMA3A inhibited OSCC cell migration, suggesting that the NRP1 receptor was bioactive in OSCC. In conclusion, NRP1 is regulated in the oral epithelium and is selectively up-regulated during epithelial dysplasia. NRP1 may function as a reservoir to sequester proangiogenic ligands within the neoplastic compartment, thereby recruiting neovessels toward tumor cells.

2013-01-01

Oral squamous cell carcinomas (OSCC) often arise from dysplastic lesions. The role of cancer stem cells in tumour initiation is widely accepted, yet the potential existence of pre-cancerous stem cells in dysplastic tissue has received little attention. Cell lines from oral diseases ranging in severity from dysplasia to malignancy provide opportunity to investigate the involvement of stem cells in malignant progression from dysplasia. Stem cells are functionally defined by their ability to generate hierarchical tissue structures in consortium with spatial regulation. Organotypic cultures readily display tissue hierarchy in vitro; hence, in this study, we compared hierarchical expression of stem cell-associated markers in dermis-based organotypic cultures of oral epithelial cells from normal tissue (OKF6-TERT2), mild dysplasia (DOK), severe dysplasia (POE-9n) and OSCC (PE/CA P J15). Expression of CD44, p75(NTR), CD24 and ALDH was studied in monolayers by flow cytometry and in organotypic cultures by immunohistochemistry. Spatial regulation of CD44 and p75(NTR) was evident for organotypic cultures of normal (OKF6-TERT2) and dysplasia (DOK and POE-9n) but was lacking for OSCC (PE/CA PJ15)-derived cells. Spatial regulation of CD24 was not evident. All monolayer cultures exhibited CD44, p75(NTR), CD24 antigens and ALDH activity (ALDEFLUOR(®) assay), with a trend towards loss of population heterogeneity that mirrored disease severity. In monolayer, increased FOXA1 and decreased FOXA2 expression correlated with disease severity, but OCT3/4, Sox2 and NANOG did not. We conclude that dermis-based organotypic cultures give opportunity to investigate the mechanisms that underlie loss of spatial regulation of stem cell markers seen with OSCC-derived cells. © 2012 John Wiley & Sons A/S.

Hypoparathyroidism, deafness and renal dysplasia (HDR) syndrome is a rare autosomal dominant disorder, secondary to mutations in the GATA-3 gene. Due to its wide range of penetrance and expressivity, the disease may not always be recognized. We herein describe clinical and genetic features of patients with HDR syndrome, highlighting diagnostic clues. Medical records of eight patients from five unrelated families exhibiting GATA-3 mutations were reviewed retrospectively, in conjunction with all previously reported cases. HDR syndrome was diagnosed in eight patients between the ages of 18 and 60 years. Sensorineural deafness was consistently diagnosed, ranging from clinical hearing loss since infancy in seven patients to deafness detected only by audiometry in adulthood in one single patient. Hypoparathyroidism was present in six patients (with hypocalcaemia and inaugural seizures in two out of six). Renal abnormalities observed in six patients were diverse and of dysplastic nature. Three patients displayed nephrotic-range proteinuria and reached end-stage renal disease (ESRD) between the ages of 19 and 61 years, whilst lesions of focal and segmental glomerulosclerosis were histologically demonstrated in one of them. Interestingly, phenotype severity differed significantly between a mother and son within one family. Five new mutations of GATA-3 were identified, including three missense mutations affecting zinc finger motifs [NM_001002295.1: c.856A>G (p.N286D) and c.1017C>G (p.C339W)] or the conserved linker region [c.896G>A (p.R299G)], and two splicing mutations (c.924+4_924+19del and c.1051-2A>G). Review of 115 previously reported cases of GATA-3 mutations showed hypoparathyroidism and deafness in 95% of patients, and renal abnormalities in only 60%. Overall, 10% of patients had reached ESRD. We herein expand the clinical and mutational spectrum of HDR syndrome, illustrating considerable inter- and intrafamilial phenotypic variability. Diagnosis of HDR should be

End-stage renal disease inthe course ofurinary tract defects inWolf–Hirschhorn syndrome – case report

Directory of Open Access Journals (Sweden)

Katarzyna Jungiewicz

2014-09-01

Full Text Available Wolf–Hirschhorn syndrome is a complex development disorder containing facial dysmorphy, development retardation, growth impairment, muscular hypotonia and occurrence of paroxysmal disorders. Characteristic dysmorphic features are hypertelorism, oblique eyelids, prominent high forehead, wide nose, short philtrum, micrognathia, low set dysplastic ears and gothic palate, in some cases cleft palate. Those features are described as “Greek warrior helmet”. Dysmorphia can be accompanied by various congenital defects, such as growth impairment, heart defects, coloboma, urogenital and skeletal abnormalities, deafness, and in 20% of patients kidney defects, which could lead in some cases to end of stage renal disease. Observed disorders are resulting from deletion of short arm of 4th chromosome and their severity, clinical outcome and intensity of  development retardation depend on deletion size. In our article we present a  boy with severe case of Wolf–Hirschhorn syndrome accompanied by renal dysplasia of his only kidney, which lead to end of stage renal disease during his infancy. He has been treated with peritoneal dialysis since then. In our patient’s case variety of congenital defects and severe development retardation cause bad clinical outcome and serious prognosis. Patient like that requires multidisciplinary medical care. Decision about initiation of renal replacement therapy in such a patient is still an important ethical dilemma.

A verrucous epidermal nevus (VEN) is a skin disorder that has been treated using different treatment modalities with varying results. Ablative lasers such as carbon dioxide laser (CO 2 ) and erbium:yttrium-aluminum-garnet (Er:YAG) laser have been considered as the gold standard for the treatment of epidermal nevi. To evaluate and compare the efficacy, postoperative wound healing and side effects of pulsed CO 2 laser and Er:YAG laser for the treatment of verrucous epidermal nevi. Twenty patients with localized VEN were randomly divided into two groups. Group 1 was administered CO 2 laser and group 2 underwent Er:YAG laser treatment. A blinded physician evaluated the photographs and dermoscopic photomicrographs for the efficacy and possible side effects. All patients received one treatment session and were followed up over a 6-month period. Both lasers induced noticeable clinical improvement, but there were no significant differences between two lasers in treatment response, patient satisfaction, duration of erythema and side effects. The average time to re-epithelialization was 13.5 days with CO 2 and 7.9 days with Er:YAG laser (plaser group and no lesional recurrence was detected in CO 2 laser group since treatment. Apart from re-epithelialization, both lasers showed equivalent outcomes with respect to treatment response, patient satisfaction, side effects and complications.

Nonlinear optical microscopy combined with fluorescence lifetime imaging is a non-invasive imaging technique, based on the study of fluorescence decay times of naturally occurring fluorescent molecules, enabling a noninvasive investigation of the biological tissue with subcellular resolution. Cancer exhibits altered cellular metabolism, which affects the autofluorescence of metabolic cofactors NAD(P)H and FAD. In this study features of tumor metabolism in different systems of organization (from cell culture to patient lesion) was showed. The observed differences in the relative contributions of free NAD(P)H and FAD testify to an increased a glycolytic metabolism in cancer cells compare to fibroblasts. In 3D spheroids, the cells of the proliferating zone had greater a1 and lower tm values than the cells of the quiescent zone, which likely is a consequence of their higher glycolytic rate. During the growth of colorectal cancer in the experimental mouse model, the contribution of the free component of NAD(P)H was increased. Dysplastic nevus and melanoma is characterized by raised contribution of free NADH compare to healthy skin. Therefore, melanoma cells had very short value of τ1.

Full Text Available To investigate whether pigmentation genes involved in the melanogenic pathway (melanogenesis contributed to melanoma predisposition, we compared pigmentary genetics with quantitative skin pigmentation measurements, the number of atypical nevi, the total nevus count, and the familial atypical multiple mole and melanoma (FAMMM syndrome. We typed 32 pigmentary SNP markers and sequenced MC1R in 246 healthy individuals and 116 individuals attending periodic control for malignant melanoma development, 50 of which were diagnosed with FAMMM. It was observed that individuals with any two grouped MC1R variants (missense, NM_002386:c. 456C > A (p.TYR152*, or NM_002386:c.83_84insA (p.Asn29Glnfs*14 had significantly (p<0.001 lighter skin pigmentation of the upper-inner arm than those with none or one MC1R variant. We did not observe any significant association of the MC1R variants with constitutive pigmentation measured on the buttock area. We hypothesize that the effect of MC1R variants on arm pigmentation is primarily reflecting the inability to tan when subjected to UVR. A gender specific effect on skin pigmentation was also observed, and it was found that the skin pigmentation of females on average were darker than that of males (p<0.01. We conclude that MC1R variants are associated with quantitative skin colour in a lightly pigmented Danish population. We did not observe any association between any pigmentary marker and the FAMMM syndrome. We suggest that the genetics of FAMMM is not related to the genetics of the pigmentary pathway.

Diagnostic Exome Sequencing (DES) has been shown to be an effective tool for diagnosis individuals with suspected genetic conditions. We report a male infant born with multiple anomalies including bilateral dysplastic kidneys, cleft palate, bilateral talipes, and bilateral absence of thumbs and first toes. Prenatal testing including chromosome analysis and microarray did not identify a cause for the multiple congenital anomalies. Postnatal diagnostic exome studies (DES) were utilized to find a molecular diagnosis for the patient. Exome sequencing of the proband, mother, and father showed a previously unreported maternally inherited RNA binding motif protein 10 (RBM10) c.1352_1353delAG (p.E451Vfs*66) alteration. Mutations in RBM10 are associated with TARP syndrome, an X-linked recessive disorder originally described with cardinal features of talipes equinovarus, atrial septal defect, Robin sequence, and persistent left superior vena cava. DES established a molecular genetic diagnosis of TARP syndrome for a neonatal patient with a poor prognosis in whom traditional testing methods were uninformative and allowed for efficient diagnosis and future reproductive options for the parents. Other reported cases of TARP syndrome demonstrate significant variability in clinical phenotype. The reported features in this infant including multiple hemivertebrae, imperforate anus, aplasia of thumbs and first toes have not been reported in previous patients, thus expanding the clinical phenotype for this rare disorder.

A 5-year-old boy presented with worsening headaches for 3 months. On examination, he was found to have a hairless fatty tissue nevus of the scalp (nevus psiloliparus), subcutaneous soft tissue masses on the right side of his face, neck, mandible and right buttock and epibulbar dermoid of the right eye (choristoma) (Figs. 1A, B). Magnetic resonance imaging revealed a large suprasellar mass, which was debulked and found to be a pilocytic astrocytoma. Testing was not performed for the BRAF/KIAA1549 fusion or BRAFV600E mutation. Seven years later, he was started on adjuvant chemotherapy for gradual tumor progression. Over the ensuing 3 years, he had further disease progression despite treatment with 3 frontline chemotherapy regimens: vinblastine, carboplatin/vincristine, and irinotecan/bevacizumab. Targeted sequencing of tissue from the right gluteal mass, revealed a mosaic activating FGFR1 c.1966A>G (p.Lys656Glu) mutation, absent in normal left gluteal tissue, confirming the diagnosis of encephalocraniocutaneous lipomatosis (ECCL), belonging to the family of RASopathies (including neurofibromatosis type I, Noonan syndrome, Costello syndrome), with constitutive activation of the mitogen-activated protein kinase (MAPK) pathway, and an increased risk of developing neoplasms. He was started on trametinib, a MEK inhibitor, off-label, targeting the MAPK pathway downstream from FGFR1, with stable tumor size at last follow-up, after 6 months on therapy.

Lethal genes surviving by mosaicism: a possible explanation for sporadic birth defects involving the skin.

Science.gov (United States)

Happle, R

1987-04-01

A genetic concept is advanced to explain the origin of several sporadic syndromes characterized by a mosaic distribution of skin defects. It is postulated that these disorders are due to the action of a lethal gene surviving by mosaicism. The presence of the mutation in the zygote will lead to death of the embryo at an early stage of development. Cells bearing the mutation can survive only in a mosaic state, in close proximity with normal cells. The mosaic may arise either from a gametic half chromatid mutation or from an early somatic mutation. This concept of origin is proposed to apply to the Schimmelpenning-Feuerstein-Mims syndrome, the McCune-Albright syndrome, the Klippel-Trenaunay syndrome, the Sturge-Weber syndrome, and neurocutaneous melanosis. Moreover, this etiologic hypothesis may apply to two other birth defects that have recently been delineated, the Proteus syndrome (partial gigantism of hands or feet, hemihypertrophy, macrocephaly, linear papillomatous epidermal nevus, subcutaneous hemangiomas and lipomas, accelerated growth, and visceral anomalies), and the Delleman-Oorthuys syndrome (orbital cyst, porencephaly, periorbital appendages, and focal aplasia of the skin.

Missing cells: pathophysiology, diagnosis and management of (pancytopenia in childhood

Full Text Available Peripheral blood cytopenia in children can be due to a variety of acquired or inherited diseases. Genetic disorders affecting a single hematopoietic lineage are frequently characterized by typical bone marrow findings such as lack of progenitors or maturation arrest in congenital neutropenia or a lack of megakaryocytes in congenital amegakaryocytic thrombocytopenia whereas antibody mediated diseases such as autoimmune neutropenia are associated with a rather unremarkable bone marrow morphology. In contrast, pancytopenia is frequently associated with a hypocellular bone marrow and the differential diagnosis includes acquired aplastic anemia, myelodysplastic syndrome, inherited bone marrow failure syndromes such as Fanconi anemia and dyskeratosis congenita and a variety of immunological disorders including hemophagocytic lymphohistiocytosis. Thorough bone marrow analysis is of special importance for the diagnostic work-up of most patients. Cellularity, cellular composition and dysplastic signs are the cornerstones of the differential diagnosis. Pancytopenia in the presence of a normo- or hypercellular marrow with dysplastic changes may indicate myelodysplastic syndrome. More challenging for the hematologist is the evaluation of the hypocellular bone marrow. Although aplastic anemia and hypocellular refractory cytopenia of childhood (RCC can reliably be differentiated on a morphological level the overlapping pathophysiology remains a significant challenge for the choice of the therapeutic strategy. Furthermore, inherited bone marrow failure syndromes are usually associated with the morphological picture of RCC and the recognition of these entities is essential as they often present a multisystem disease requiring different diagnostic and therapeutic approaches. This paper gives an overview over the different disease entities presenting with (pancytopenia, their pathophysiology, characteristic bone marrow findings and therapeutic approaches.

Ten (dermato)pathologists studied 50 cutaneous melanocytic lesions including common naevocellular naevi, dysplastic naevi (DN), melanomas in situ and invasive primary melanomas, with emphasis on the histological criteria of DN. Using a standardised form, 20 defined histopathological features were scored (semi)quantitatively. Concordance of diagnosis, efficacy and reproducibility of features were investigated. DN were distinguished well from the other entities (mean Po 0.87). Agreement on the degree of atypia of DN was low. The reproducibility of the scoring was best for the following features: irregular nests, lymphohistiocytic infiltrate, marked junctional proliferation and large nuclei. The overall values of these features to discriminate between DN and non-DN were better than for the other features studied. Using the presence of at least three of the four features as a condition for the diagnosis of DN, values for sensitivity, specificity and positive and negative predictive values were 0.86, 0.91, 0.96 and 0.73, respectively. On the basis of the results these features seem best suited as histological criteria for the diagnosis of DN.

Full Text Available Abstract Oral-Facial-Digital Syndrome type VI (OFD VI represents a rare phenotypic subtype of Joubert syndrome and related disorders (JSRD. In the original report polydactyly, oral findings, intellectual disability, and absence of the cerebellar vermis at post-mortem characterized the syndrome. Subsequently, the molar tooth sign (MTS has been found in patients with OFD VI, prompting the inclusion of OFD VI in JSRD. We studied the clinical, neurodevelopmental, neuroimaging, and genetic findings in a cohort of 16 patients with OFD VI. We derived the following inclusion criteria from the literature: 1 MTS and one oral finding and polydactyly, or 2 MTS and more than one typical oral finding. The OFD VI neuroimaging pattern was found to be more severe than in other JSRD subgroups and includes severe hypoplasia of the cerebellar vermis, hypoplastic and dysplastic cerebellar hemispheres, marked enlargement of the posterior fossa, increased retrocerebellar collection of cerebrospinal fluid, abnormal brainstem, and frequently supratentorial abnormalities that occasionally include characteristic hypothalamic hamartomas. Additionally, two new JSRD neuroimaging findings (ascending superior cerebellar peduncles and fused thalami have been identified. Tongue hamartomas, additional frenula, upper lip notch, and mesoaxial polydactyly are specific findings in OFD VI, while cleft lip/palate and other types of polydactyly of hands and feet are not specific. Involvement of other organs may include ocular findings, particularly colobomas. The majority of the patients have absent motor development and profound cognitive impairment. In OFD VI, normal cognitive functions are possible, but exceptional. Sequencing of known JSRD genes in most patients failed to detect pathogenetic mutations, therefore the genetic basis of OFD VI remains unknown. Compared with other JSRD subgroups, the neurological findings and impairment of motor development and cognitive functions in OFD

The presentation herewith as scripted is to describe a case with Nevus sebaceous with oral manifestations. Nevus Sebaceous or Jadassohn's nevus is an epidermal nevus with predominant sebaceous glands seen histologically. Reports of oral involvement have been few ranging from papillomatous growths of the tongue, gingiva, palate to dental abnormalities such as anodontia and dysodontia. The present case describes a nevus sebaceous present on the right half of the face and neck, showing intraoral papillomatous growth on the lateral part of the tongue on the right side. The patient was healthy and did not report involvement of any other organ systems. Intraoral involvement may be seen in patients with Nevus Sebaceous, hence proper screening is important. In patients presenting with large nevi on the head and neck such as ours, involvement of other systems such as ocular, neurologic and oral lesions may be seen, therefore screening of such patients is of importance. Patients with nevus sebaceous may be predisposed to the occurrence of tumours. Therefore, careful screening of such patients is necessary.

The term "phacomatosis" refers to a growing number of sporadic genetic skin disorders characterized by the combination of two or more different nevi and possibly resulting from non-allelic twin spotting. While phacomatosis pigmentovascularis (PPV) and pigmentokeratotica represent the most common patterns, some patients do not fit with either condition and are temporarily classified as unique phenotypes. We report on an 8-year-old boy with striking right hemihypoplasia, resulting in limb asymmetry and fixed dislocation of right hip. Skin on the affected side showed three distinct nevi: (i) A whorled, hairless nevus of the scalp in close proximity with (ii) epidermal hyperpigmentation following lines of Blaschko on the neck and right upper limb, and (iii) multiple telangiectatic nevi of the right lower limb and hemiscrotum. Didymosis atricho-melanotica was proposed for the combination of adjacent patchy congenital alopecia and linear hyperpigmentation, while phacomatosis atricho-pigmento-vascularis appears to define the entire cutaneous phenotype, thus implying the involvement of three neighboring loci influencing the development of distinct constituents of the skin. Given the striking asymmetry of the observed phenotype, the effect of mosaicism (either genomic or functional) for a mutation in a single gene with pleiotropic action and influenced by the lateralization pattern of early development cannot be excluded.

BACKGROUND Current surveillance guidelines for patients with long-standing ulcerative colitis (UC) recommend repeated colonoscopy with random biopsies, which is time-consuming, discomforting and expensive. A less invasive strategy is to identify neoplasia by analyzing biomarkers from the more accessible rectum to predict the need for a full colonoscopy. The goal of this pilot study is to evaluate whether optical markers of rectal mucosa derived from a novel optical technique – partial-wave spectroscopic microscopy (PWS) could identify UC patients with high-grade dysplasia (HGD) or cancer (CA) present anywhere in their colon. METHODS Banked frozen non-dysplastic mucosal rectal biopsies were used from 28 UC patients (15 without dysplasia and 13 with concurrent HGD or CA). The specimen slides were made using a touch prep method and underwent PWS analysis. We divided the patients into two groups: 13 as a training set and an independent 15 as a validation set. RESULTS We identified six optical markers, ranked by measuring the information gain with respect to the outcome of cancer. The most effective markers were selected by maximizing the cross validated training accuracy of a Naive Bayes classifier. The optimal classifier was applied to the validation data yielding 100% sensitivity and 75% specificity. CONCLUSIONS Our results indicate that the PWS-derived optical markers can accurately predict UC patients with HGD/CA through assessment of rectal epithelial cells. By aiming for a high sensitivity, our approach could potentially simplify the surveillance of UC patients and improve overall resource utilization by identifying patients with HGD/CA who should proceed with colonoscopy.

In 21 patients with a variety of skin tumors (squamous cell carcinomas, malignant melanomas, basal cell epitheliomas and mycosis fungoides) or precancerous lesions (Bowen's disease, actinic keratosis, junctional nevus cell nevus) the radioactive phosphorus uptake test demonstrates a sign ficantly increased concentration of P 32 in those tumors. There were no false negative tests. The possibility of differentiation of malignant melanoma from benign nevus cell nevus and the early recognition of cutaneous metastases is described. Furthermore recurrence of previously irradiated or excised basal cell epitheliomas can be detected without a biopsy. No hematological side-effects were observed. (orig.) [de

The objective of this study is to report the prenatal ultrasound scan findings in four fetuses from two families postnatally diagnosed with 17q12 microdeletion syndrome on microarray CGH and review the literature. We report two families presenting with prenatally detected hyperechogenic kidneys. In family 1, the mother had three pregnancies complicated by anhydramnios with bilateral hyperechogenic kidneys, hyperechogenic enlarged cystic kidneys, and bilateral hyperechogenic kidneys with polyhydramnios respectively. In family 2, prenatal ultrasound scans detected hyperechogenic kidneys. A pubmed search for all reported cases of 17q12 deletion between 2005 and 2015 was performed. All publications were reviewed, and findings summarised. Fourteen publications were deemed suitable for literature review; there was a diagnosis of 17q12 deletion with documented prenatal findings in 25 cases. Prenatal renal anomalies were reported in 88% of these cases. Anomalies were documented from 15 weeks, and most common presentation was hyperechogenic, muticystic, or enlarged kidneys. Both oligohydramnios and polyhydramnios were seen. Postnatal renal ultrasound scan findings were of muticystic or multicystic dysplastic kidney. There did not appear to be correlation of prenatal presentation and severity of renal disease. Prenatal testing should be offered to all cases of hyperechogenic kidneys, with unknown cause. © 2015 John Wiley & Sons, Ltd.

Sturge-Weber syndrome (SWS), also known as encephalotrigeminal angiomatosis, is a condition which includes leptomeningeal hemangioma, facial angiomatosis or nevus flammeus, and ocular changes. SWS can lead to severe complications of anterior segment involving conjunctiva and eyelids, whereas posterior segment of the eye may also be affected by diffuse choroidal hemorrhages. This article was written with the objectives to determine the pathophysiology, diagnosis, and treatment of glaucoma associated with this rare and challenging disorder. A detailed literature search was conducted on PubMed, EMBASE, Cochrane Library, and Google Scholar using the key words. Forty-five articles matched our inclusion criteria that were included in this systematic review. Glaucoma is the one of the commonest ocular manifestations of SWS. It is caused by anterior chamber malformations, increased pressure in the episcleral veins, and changes in ocular hemodynamics. Glaucoma associated with SWS is usually congenital but can develop adults as well. The treatment of glaucoma associated with SWS is quite challenging because of early-onset, severe visual field impairment at the time of diagnosis, and unresponsiveness to standard medical treatment. Several surgical procedures have been devised but the long-term control of the intraocular pressure and visual function remain unsatisfactory. Modifications in the filtration surgery techniques and use of newer anti-fibrotic agents have produced good control of intraocular pressure. Management of glaucoma associated with SWS is multi-dimensional and needs both medical and surgical interventions for better control. The treatment should be devised on case to case basis depending upon the intraocular pressure, stage of the disease, and type of glaucoma.

Full Text Available A three-year-old girl presented with primary complaint of severe low back pain with radiation to both lower limbs below the knees since 2 months following history of fall and marked restriction of her daily routine activities. After clinicoradiological evaluation she was diagnosed of having dysplastic L5-S1 spondyloptosis. A staged procedure was planned after thorough discussion with her parents. During initial stage she underwent posterior decompression along L5-S1 segment including exposure of bilateral L5 and S1 nerve roots followed by instrumented reduction (L3-S2 5.5 mm pedicle screws utilizing a rotational-translational technique. No interbody fusion was done at L5-S1 level and inner nuts of bilateral L3, L4, and S2 screws were intentionally kept loose. Subsequently after about symptom-free three-year follow up, she presented with recurrence of symptoms and underwent revision surgery as per initial plan discussed with her parents. Removals of posterior implants were done followed by stabilization with larger diameter pedicle screws (6.5 mm at L5 and S1 level. During the same stage through anterior transperitoneal approach L5-S1 interbody fusion was done. At one-year follow-up after second-stage definitive surgery, patient remains symptom-free and fully active without any radiological evidence of reduction loss or implant failure.

Many childhood diseases often present with skin abnormalities with which radiologists are largely unfamiliar. Knowledge of associated dermatologic manifestations may aid the radiologist in confirming the diagnosis and recommending targeted imaging of affected organs. We review the imaging findings in childhood diseases associated with dermatologic manifestations. Diseases include dermatologic findings which herald underlying malignancy (Neuroblastoma, leukemia/lymphoma, Langerhans cell histiocytosis),are associated with risk of malignancy (Epidermolysis Bullosa, basal cell nevus syndrome, Cowden's syndrome, Tuberous Sclerosis),or indicate a systemic inflammatory/immune disorder (Kawasaki's disease, Henoch Schonlein Purpura, systemic lupus erythematosus, scleroderma, sarcoidosis, dermatomyositis and immune thrombocytopenic purpura). Familiarity with pertinent findings in childhood diseases presenting with dermatologic manifestations in childhood diseases aids the radiologist in confirming the diagnosis and guiding imaging workup.

Indian hedgehog (Ihh) signaling is a major determinant of various processes during embryonic development and has a pivotal role in embryonic skeletal development. A specific spatial and temporal expression of Ihh within the developing limb buds is essential for accurate digit outgrowth and correct digit number. Although missense mutations in IHH cause brachydactyly type A1, small tandem duplications involving the IHH locus have recently been described in patients with mild syndactyly and craniosynostosis. In contrast, a ∼600-kb deletion 5' of IHH in the doublefoot mouse mutant (Dbf) leads to severe polydactyly without craniosynostosis, but with craniofacial dysmorphism. We now present a patient resembling acrocallosal syndrome (ACS) with extensive polysyndactyly of the hands and feet, craniofacial abnormalities including macrocephaly, agenesis of the corpus callosum, dysplastic and low-set ears, severe hypertelorism and profound psychomotor delay. Single-nucleotide polymorphism (SNP) array copy number analysis identified a ∼900-kb duplication of the IHH locus, which was confirmed by an independent quantitative method. A fetus from a second pregnancy of the mother by a different spouse showed similar craniofacial and limb malformations and the same duplication of the IHH-locus. We defined the exact breakpoints and showed that the duplications are identical tandem duplications in both sibs. No copy number changes were observed in the healthy mother. To our knowledge, this is the first report of a human phenotype similar to the Dbf mutant and strikingly overlapping with ACS that is caused by a copy number variation involving the IHH locus on chromosome 2q35.

Noonan syndrome is a heterogenous rasopathy typically presenting with short stature, characteristic facial features, cardiac abnormalities including pulmonic valve stenosis, ASD and hypertrophic cardiomyopathy (HCM), cryptorchidism, ectodermal abnormalities, and learning differences. The phenotype is variable, and limited genotype phenotype correlation exists with SOS1 mutations often associated with normal cognition and stature, RAF1 mutations entailing a high HCM risk, and certain PTPN11 mutations predisposing to juvenile myelomonocytic leukemia. The recently identified SHOC2 mutation (p.Ser2Gly) causes Noonan syndrome with loose anagen hair. We report five patients with this mutation. All had skin hyperpigmentation, sparse light colored hair, increased fine wrinkles, ligamentous laxity, developmental delay, and 4/4 had a structural cardiac anomaly. Hypotonia and macrocephaly occurred in 4/5 (80%); 3/5 (60%) had polyhydramnios, increased birth weight or required use of a feeding tube. Distinctive brain abnormalities included relative megalencephaly and enlarged subarachnoid spaces suggestive of benign external hydrocephalus, and a relatively small posterior fossa as indicated by a vertical tentorium. The combination of a large brain with a small posterior fossa likely resulted in the high rate of cerebellar tonsillar ectopia (3/4; 75%). Periventricular nodular heterotopia was seen in one patient with a thick and dysplastic corpus callosum. We report on the first hematologic neoplasm, myelofibrosis, in a 2-year-old patient with SHOC2 mutation. Myelofibrosis is exceedingly rare in children and young adults. The absence of a somatic JAK2 mutation, seen in the majority of patients with myelofibrosis, is noteworthy as it suggests that germline or somatic SHOC2 mutations are causally involved in myelofibrosis.

Lasers are increasingly used for elective ablation of melanocytic nevi (MN). However, the associated risks of treating MN with lasers are debated and not well studied. Theoretical risks include inadvertently treating a melanoma mistaken for a nevus, the inability to remove all nevus cells and the possibility for residual cells to undergo malignant transformation, and the difficulty in clinically monitoring the remnant nevus for melanoma progression. Additional concerns include the morphological suitability of a lesion for laser removal and managing patients' expectations about the variable cosmetic outcomes. These potential issues have prompted us to outline some practical suggestions for clinicians and patients to consider when determining the suitability of a nevus for laser ablation. The choice to perform laser removal of a nevus is personal, both from the perspective of the treating physician and that of the person being treated. While acknowledging some uncertainty, we believe that these suggestions can help mitigate risk and improve patient outcomes. Lasers Surg.

Fremont, Oliver T; Chan, James C M

2012-02-01

We aim to review the clinical features of two renal tubular disorders characterized by sodium and potassium wasting: Bartter syndrome and Gitelman syndrome. Selected key references concerning these syndromes were analyzed, together with a PubMed search of the literature from 2000 to 2011. The clinical features common to both conditions and those which are distinct to each syndrome were presented. The new findings on the genetics of the five types of Bartter syndrome and the discrete mutations in Gitelman syndrome were reviewed, together with the diagnostic workup and treatment for each condition. Patients with Bartter syndrome types 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. They present with symptoms, often quite severe in the neonatal period. Patients with classic Bartter syndrome type 3 present later in life and may be sporadically asymptomatic or mildly symptomatic. The severe, steady-state hypokalemia in Bartter syndrome and Gitelman syndrome may abruptly become life-threatening under certain aggravating conditions. Clinicians need to be cognizant of such renal tubular disorders, and promptly treat at-risk patients.

Protein kinase C βII promotes melanogenesis and affects proliferation of melanocytic cells but is frequently absent or decreased in melanoma cells in vitro. To investigate PKC-βII expression and spatial distribution within a lesion in various benign and malignant melanocytic proliferations. Expression of PKC-βII was semiquantitatively assessed in the various existing compartments (intraepidermal [not nested], junctional [nested], and dermal) of benign (n = 43) and malignant (n = 28) melanocytic lesions by immunohistochemistry. Melanocytes in the basal layer of normal skin or in lentigo simplex stained strongly for PKC-βII. Common nevi lacked completely PKC-βII. All other lesions expressed variably PKC-βII, with cutaneous melanoma metastases displaying the lowest rate of positivity (14%). In the topographical analysis within a lesion, PKC-βII expression was largely retained in the intraepidermal and junctional part of all other lesions (dysplastic nevus, lentigo maligna, and melanoma). Reduced expression of PKC-βII was found in the dermal component of benign and malignant lesions ( P = .041 vs intraepidermal). PKC-βII expression in the various compartments did not differ significantly between benign and malignant lesions. The current study revealed a significant correlation between PKC-βII expression and spatial localization of melanocytes, with the lowest expression found in the dermal compartment and the highest in the epidermal compartment.

Malignant melanoma (MM) is a type of malignant tumor, which originates from neural crest melanocytes. MM progresses rapidly and results in a high mortality rate. The present study aims to investigate the expression of microphthalmia transcription factor (MITF), the S100 protein, and HMB-45 in MM and pigmented nevi. A total of 32 MM samples (including three skin metastasis, three lymph node metastasis and two spindle cell MM samples), two Spitz nevus samples, four pigmented nevus samples and two blue nevus samples were collected. The expression levels of S100 protein, HMB-45, and MITF were observed via immunostaining. The S100 protein exhibited high positive rates in MM and pigment disorders (96.7 and 100%, respectively), but with low specificity. The S100 protein was also expressed in fibroblasts, myoepithelial cells, histocytes and Langerhans cells in normal skin samples. HMB-45 had high specificity. Its positive expression was only confined to MM cells and junctional nevus cells. Furthermore, HMB-45 was not expressed in melanocytes in the normal tissue samples around the tumor or in the benign intradermal nevus cells. MITF exhibited high specificity and high sensitivity. It was expressed in the nuclei of melanocytes, MM cells and nevus cells. It was observed to be strongly expressed in metastatic MM and spindle cell MMs. Thus, MITF may present as a specific immunomarker for the diagnosis and differential diagnosis of MM.

Narrow duplicated internal auditory canal (IAC) is a rare malformation of the temporal bone that is associated with ipsilateral congenital sensorineural hearing loss. This may be an isolated finding or a part of a syndrome. Radiological examination should demonstrate aplasia or hypoplasia of the neural components of the narrow IAC, to guide the surgical approach. We report a 7-year-old boy with Klippel-Feil syndrome with a narrow double IAC with no sensorineural hearing loss but with conductive hearing loss. In this patient, the IAC consisted of two separate narrow bony canals clearly seen on 3D temporal bone CT and one nerve that was delineated on MRI. The contralateral external auditory canal was stenotic and the ossicles were dysplastic. (orig.)

The paper describes the maxillo-facial and dental anomalies observed in some chromosome and non-chromosome poly-malformative syndromes ("Cri du chat" syndrome; Wilms' tumour; Sotos' syndrome; Goldenhar's syndrome). The Authors emphasise the possibility of diagnosing these multiple deformity syndromes from maxillo-facial alterations in early infancy; anomalous tooth position and structure cal also be successfully treated immediately after the first appearance of teeth. This is a particularly promising field of pediatrics and preventive pediatric medicine.

Full Text Available Retinoids have been used for years as monotherapy and/or in combination for treatment and suppression of cutaneous malignancies in patients with basal cell nevus syndrome, xeroderma pigmentosum, or cutaneous T-cell lymphoma (CTCL basal cell carcinoma (BCC. We report 4 cases with BCC confirmed by histopathology who were treated by short-term systemic acitretin combined with retinoic acid 0.1% cream. The 4 cases with BCC showed good response to the treatment without severe adverse effects during treatment and follow-up. The finding suggests that acitretin may be an appropriate treatment option for elderly patients who require less invasive treatment for BCC.

The aim of this study was to investigate the developmental trajectories of verbal aggression, physical aggression, and temper tantrums in four genetic syndrome groups. Participants were part of the Australian Child to Adult Development Study (ACAD), which collected information from a cohort of individuals with an intellectual disability at five time points over 18 years. Data were examined from a total of 248 people with one of the four following syndromes: Down syndrome, Fragile X syndrome, Prader-Willi syndrome, or Williams syndrome. Changes in behaviors were measured using validated items from the Developmental Behavior Checklist (DBC). The results indicate that, while verbal aggression shows no evidence of diminishing with age, physical aggression, and temper tantrums decline with age before 19 years for people with Down syndrome, Fragile X syndrome, and William syndrome; and after 19 years for people with Prader-Willi syndrome. These findings offer a somewhat more optimistic outlook for people with an intellectual disability than has previously been suggested. Research is needed to investigate the mechanisms predisposing people with PWS to persistence of temper tantrums and physical aggression into adulthood. © 2015 Wiley Periodicals, Inc.

Muhury Manas

2009-10-01

Full Text Available Context: Dysplastic changes are well documented in myelodysplastic syndromes (MDS. However, they are also observed in non-MDS hematological conditions. Aims: To evaluate the megakaryocytic alterations in the bone marrow aspirations in cases of non-MDS related thrombocytopenia. Setting and Design: A prospective study of 144 bone marrow aspirates was conducted in the department of pathology, Kasturba Medical College, Mangalore. The aspirates were studied to assess the number and morphology of the megakaryocytes in non-MDS related thrombocytopenia and evaluate their significance when compared to changes in MDS. Materials and Methods: The bone marrow aspiration smears were stained with Leishman stain and examined under light microscope. Statistical Analysis Used: Fisher′s exact test. A P value less than 0.05 was considered significant. Sensitivity and specificity was calculated for those features which were significant in the relevant hematological disorders. Results: The sensitivity of immature megakaryocytes, dysplastic forms and micromegakaryocytes in cases of immune thrombocytopenic purpura was 100%, 89% and 42% respectively. The specificity of emperipolesis was 74%. In cases of infection-associated thrombocytopenia, immature megakaryocytes had a sensitivity of 100% and cytoplasmic vacuolization were 86% specific. The sensitivity of the dysplastic forms in megaloblastic anemia was 75%. However, no platelet budding was observed. The presence of micromegakaryocyte had a specificity of 83% in MDS, and was statistically significant when compared to cases of non-MDS conditions (P< 0.05. Conclusions: Careful understanding of the morphological changes of megakaryocytes in bone marrow aspirates can improve the diagnostic accuracy for a wide range of hematological disorders thereby enabling proper therapeutic interventions.

Bi-allelic germline mutations of one of the DNA mismatch repair genes, so far predominantly found in PMS2, cause constitutional MMR-deficiency syndrome. This rare disorder is characterised by paediatric intestinal cancer and other malignancies. We report the clinical, immunohistochemical and genetic characterisation of four families with bi-allelic germline PMS2 mutations. We present an overview of the published gastrointestinal manifestations of CMMR-D syndrome and propose recommendations for gastro-intestinal screening. The first proband developed a cerebral angiosarcoma at age 2 and two colorectal adenomas at age 7. Genetic testing identified a complete PMS2 gene deletion and a frameshift c.736_741delinsTGTGTGTGAAG (p.Pro246CysfsX3) mutation. In the second family, both the proband and her brother had multiple intestinal adenomas, initially wrongly diagnosed as familial adenomatous polyposis. A splice site c.2174+1G>A, and a missense c.137G>T (p.Ser46Ile) mutation in PMS2 were identified. The third patient was diagnosed with multiple colorectal adenomas at age 11; he developed a high-grade dysplastic colorectal adenocarcinoma at age 21. Two intragenic PMS2 deletions were found. The fourth proband developed a cerebral anaplastic ganglioma at age 9 and a high-grade colerectal dysplastic adenoma at age 10 and carries a homozygous c.2174+1G>A mutation. Tumours of all patients showed microsatellite instability and/or loss of PMS2 expression. Our findings show the association between bi-allelic germline PMS2 mutations and severe childhood-onset gastrointestinal manifestations, and support the notion that patients with early-onset gastrointestinal adenomas and cancer should be investigated for CMMR-D syndrome. We recommend yearly follow-up with colonoscopy from age 6 and simultaneous video-capsule small bowel enteroscopy from age 8. Copyright © 2011 Elsevier Ltd. All rights reserved.

Superior Mesenteric Artery Syndrome or Wilkie Syndrome

International Nuclear Information System (INIS)

Castano Llano, Rodrigo; Chams Anturi, Abraham; Arango Vargas, Paula

2009-01-01

We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

Nail-Patella syndrome (NPS) (OMIM: 161200) or hereditary onycho-osteodysplasia is an autosomal dominant disorder characterized by skeletal anomalies, nail dysplasia, renal and ocular abnor malities. The diagnosis is based on clinical and radiological findings and confirmed by the identification of a heterozygous pathogenic variant in the LMX1B gene. Management of these patients involves conti nuous follow-up and treatment ofthe orthopedical, ocular and renal problems that mayoccur. To describe a case of NPS with short stature and hypothyroidism, an association that has not been described in the literature. An eleven-year-old boy with a height of 130 cm (-2.01 Stan dard Deviations [SD]) was referred to the Endocrine Unit at the age of 2 years due to altered thyroid tests. At that time, dysplastic nails and disproportionate short stature were detected. Radiological abnormalities initially suggested a skeletal dysplasia. A primary hypothyroidism was confirmed, without anti-thyroid antibodies and with a normal thyroid ultrasound. Levothyroxine treatment was initiated. The diagnosis of NPS was confirmed by a genetic study with a single pathogenic variant in the LMX1B gene. His father presented a similar phenotype with normal stature. His bone age was equivalent to his chronological age. Laboratory screening for short stature and a GH stimulation test were normal. We present a child with proven NPS with short stature and hypothyroi dism. We did not find publications that described this triple association. It can't be ruled out that there could be a relationship between NPS and the thyroid alterations found in this patient.

Sun exposure and high prevalence of melanocytic nevi are major risk factors for melanoma, but the relationship between them is not well understood. This study examines the relationship between sun exposure (detailed by anatomic location and history of site-specific sunburns) and the presence of melanocytic nevi on 743 White children in Denver, Colorado. Parental reports of site-specific sunburns were collected annually for 2 years starting at ages 5 to 6 years. In the third year, nevi were counted and mapped by anatomic location. Nevus density was higher for boys (36.0 nevi/m2) than for girls (31.0 nevi/m2; P = 0.04). Nevus density was highest on the face, neck, and lateral forearms and was significantly higher in chronically versus intermittently sun-exposed areas (P sunburn. The face, shoulders, and back were the most frequently sunburned areas of the body. When adjusted for host factors, total number of sunburns was significantly associated with higher total nevus prevalence (P = 0.01 for one burn). Site-specific sunburns were significantly associated with nevus prevalence on the back (P = 0.03 for three or more sunburns), but not on the face, arms, or legs. In this high-risk population, there is evidence for two pathways to nevus accumulation: by chronic sun exposure and by intermittent exposure related to sunburns. PMID:17932362

Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

The aim of this study was to assess the speech perception and speech intelligibility outcome after cochlear implantation in children with malformed inner ear and to compare them with a group of congenitally deaf children implantees without inner ear malformation. Six deaf children (five boys and one girl) with inner ear malformations who were implanted and followed in our clinic were included. These children were matched with six implanted children with normal cochlea for age at implantation and duration of cochlear implant use. All subjects were tested with the internationally used battery tests of listening progress profile (LiP), capacity of auditory performance (CAP), and speech intelligibility rating (SIR). A closed and open set word perception test adapted to the Modern Greek language was also used. In the dysplastic group, two children suffered from CHARGE syndrome, another two from mental retardation, and two children grew up in bilingual homes. At least two years after switch-on, the dysplastic group scored mean LiP 62%, CAP 3.8, SIR 2.1, closed-set 61%, and open-set 49%. The children without inner ear dysplasia achieved significantly better scores, except for CAP which this difference was marginally statistically significant (p=0.009 for LiP, p=0.080 for CAP, p=0.041 for SIR, p=0.011 for closed-set, and p=0.006 for open-set tests). All of the implanted children with malformed inner ear showed benefit of auditory perception and speech production. However, the children with inner ear malformation performed less well compared with the children without inner ear dysplasia. This was possibly due to the high proportion of disabilities detected in the dysplastic group, such as CHARGE syndrome and mental retardation. Bilingualism could also be considered as a factor which possibly affects the outcome of implanted children. Therefore, children with malformed inner ear should be preoperatively evaluated for cognitive and developmental delay. In this case

Wells syndrome and its relationship to Churg-Strauss syndrome.

Ratzinger, Gudrun; Zankl, Julia; Zelger, Bernhard

2013-08-01

  Wells syndrome has been described as an inflammatory disorder based on typical clinical appearance combined with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Churg-Strauss syndrome, on the other hand, is primarily a diffuse, necrotizing vasculitis but is also typically displaying eosinophils and flame figures. Despite several parallels, the present understanding of these two diseases excludes any pathogenetic relationship.   We describe the clinical course and histopathological appearance of three patients who had initially been diagnosed with Wells syndrome that developed into Churg-Strauss syndrome during the course of their disease.   The clinical presentation of all three patients led to the diagnosis of Wells syndrome by independent specialists. Histopathology showed an eosinophilic infiltrate and flame figures next to features of leukocytoclastic vasculitis. Detailed examination revealed asthma bronchiale and additional symptoms indicating Churg-Strauss syndrome. The initial diagnosis of Wells syndrome had to be revised to Churg-Strauss syndrome.   We conclude that Wells syndrome could be the starting point of a pathogenetic process that might reach its maximum in Churg-Strauss syndrome. As a clinical consequence, patients with Wells syndrome should be evaluated and followed for Churg-Strauss syndrome. © 2013 The International Society of Dermatology.

Full Text Available Goldenhar syndrome (GHS is also known as Oculo-Auriculo-Vertebral (OAV syndrome or Branchial arch syndrome. Duane retraction syndrome (DRS is a congenital disorder of ocular motility characterized by limited abduction, adduction or both. It is unilateral in 80% of cases. The important and interesting part of this eight months old child is presence of GHS with DRS. She has bilateral invol-vement, which is seen in only 5-8% of GHS, as compared to high incidence of unilateral involve-ment. This child also had refractive error of + 6.00/ - 1.5 * 180. At four year of age her vision with glass was 6/9. Children with GHS and DRS should have early eye examination done to treat the problem of refractive error. Keywords: Duane retraction syndrome; goldenhar syndrome, refractive error.

Evaluation of diagnostic value of AgNOR and PAP in early detection of dysplastic changes in leukoplakia and lichen planus - a preliminary case-control study.

Early detection of oral cancer has been the most effective approach to reduce morbidity and mortality of cancer patients. If a lesion is clinically considered suspicious, an easily practicable, non-invasive, painless, safe, and accurate screening method for detection of the dysplastic changes is necessary. In an attempt to procure this, a study was conducted with the aim of determining the diagnostic accuracy of rapid Papanicolaou stain (PAP) and silver-stained nucleolar organizer regions (AgNOR) in brush biopsies of potentially malignant lesions for early detection of oral cancer. Brush biopsies taken from 25 cases of leukoplakia and lichen planus each were stained with rapid PAP and silver nitrate stains. Histopathological correlation was performed and further compared with rapid PAP and AgNOR for its diagnostic validity. Statistically significant increase in the mean AgNOR count was seen from normal epithelium to lichen planus to that of leukoplakia. When compared with rapid PAP, a linear correlation was seen in AgNOR counts and stages of dysplasia in leukoplakia which was also found to be statistically significant. Diagnostic accuracy for AgNOR in leukoplakia was found to be 84%, lichen planus 73%, whereas RAPID PAP showed 72% accuracy. AgNOR analysis may be useful as a quantitative marker of incipient cellular alterations and hence would be helpful in assessing suspicious lesions and thus can be regarded as a valuable adjunct. © 2016 John Wiley & Sons A/S.

Blue nevi may display significant atypia or undergo malignant transformation. Morphologic diagnosis of this spectrum of lesions is notoriously difficult, and molecular tools are increasingly used to improve diagnostic accuracy. We studied copy number aberrations in a cohort of cellular blue nevi, atypical cellular blue nevi, and melanomas ex blue nevi using Affymetrix's OncoScan platform. Cases with sufficient DNA were analyzed for GNAQ, GNA11, and HRAS mutations. Copy number aberrations were detected in 0 of 5 (0%) cellular blue nevi, 3 of 12 (25%) atypical cellular blue nevi, and 6 of 9 (67%) melanomas ex blue nevi. None of the atypical cellular blue nevi displayed more than one aberration, whereas complex aberrations involving four or more regions were seen exclusively in melanomas ex blue nevi. Gains and losses of entire chromosomal arms were identified in four of five melanomas ex blue nevi with copy number aberrations. In particular, gains of 1q, 4p, 6p, and 8q, and losses of 1p and 4q were each found in at least two melanomas. Whole chromosome aberrations were also common, and represented the sole finding in one atypical cellular blue nevus. When seen in melanomas, however, whole chromosome aberrations were invariably accompanied by partial aberrations of other chromosomes. Three melanomas ex blue nevi harbored aberrations, which were absent or negligible in their precursor components, suggesting progression in tumor biology. Gene mutations involving GNAQ and GNA11 were each detected in two of eight melanomas ex blue nevi. In conclusion, copy number aberrations are more common and often complex in melanomas ex blue nevi compared with cellular and atypical cellular blue nevi. Identification of recurrent gains and losses of entire chromosomal arms in melanomas ex blue nevi suggests that development of new probes targeting these regions may improve detection and risk stratification of these lesions.

To evaluate the clinical, CT and MR imaging findings of semicircular canal (SCC) aplasia and to evaluate if a correlation exists between these findings and the associated anomalies or syndromes. This study retrospectively reviewed the CT and MRI findings of five patients with SCC aplasia. The CT and MR findings were analyzed for SCC, direction of facial nerve canal, cochlea, vestibule, oval or round window, middle ear ossicles, and internal auditory canal (IAC). The subjects included three boys and two girls ranging in age from one to 120 months (mean age; 51 months). Four of the subjects had the CHARGE syndrome, and one had the Goldenhar syndrome. Moreover, four subjects had sensorineural hearing loss and one had combined hearing loss. The course of the facial nerve canal was abnormal in all five cases. Moreover, trapped cochlea and dysplastic modiolus were each observed in one case. Four subjects had atresia of the oval window; whereas ankylosis of the ossicles was present in three subjects. IAC stenosis was present in one patient with the CHARGE syndrome. The aberrant course of the facial nerve canal, atresia of the oval window, and abnormal ossicles were frequently associated in patients with SCC aplasia. In addition, the Goldenhar and CHARGE syndromes were also commonly associated syndromes.

LEOPARD syndrome is not linked to the Marfan syndrome and the Watson syndrome loci

The acronym LEOPARD stands for a syndromic association of Lentigines, Eletrocardiographic changes, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth and sensorineural Deafness. Inheritance is autosomal dominant with high penetrance and variable expressivity. In 1990 Torok et al. reported on the association of LEOPARD and Marfan syndrome. In addition a clinical similarity (cardiac and cutaneous involvement) exists with the Watson syndrome (neurofibromatosis and pulmonic stenosis) which is linked to the marker D17S33 on chromosome 17. We studied possible linkage of LEOPARD syndrome to the Marfan syndrome locus on chromosome 15 (D15S1, MF13, and (TAAAA)n repeats) and to the NF-1 locus on chromosome 17 in a family with 9 cases of LEOPARD syndrome. Close linkage between LEOPARD syndrome and both the Marfan locus on chromosome 15 and the NF-1 locus on chromosome 17 was excluded (lod score <-2.0 through {theta} = 0.1).

Three situations qualify as myelodysplastic syndrome, unclassifiable (MDS-U): (1) refractory cytopenia with dysplasia and 1% blasts in peripheral blood (BL), (2) pancytopenia with unilineage dysplasia (Pan), and (3) persistent cytopenia, less than 5% bone marrow blasts, and less than 10% dysplastic cells and presence of MDS-defining cytogenetic abnormalities (CG). We compared the clinicopathologic features and mutational profiles for these three groups. MDS-U cases were reviewed at four major academic institutions. Targeted next-generation sequencing for genes implicated in myeloid neoplasms was performed in a subset of cases. Twenty-seven patients were identified (six MDS-U BL, 13 MDS-U Pan, and eight MDS-U CG). Clonal cytogenetic abnormalities were found in six of six, seven of 13, and eight of eight cases in MDS-U BL, Pan, and CG, respectively (P > .05). Overall, four of six patients with MDS-U BL progressed to acute myeloid leukemia; no MDS-U Pan or CG patients did. The rates of progression-free survival and mortality (overall survival) were significantly higher in MDS-U BL compared with Pan and CG (P MDS-U BL is a distinct subset of MDS-U with a poor prognosis, while MDS-U Pan and CG are relatively indolent. Evaluation of peripheral blood smears in patients with MDS is essential for accurate classification and prognosis. © American Society for Clinical Pathology, 2017. All rights reserved.

Metabolic syndrome and polycystic ovary syndrome: an intriguing overlapping.

Caserta, Donatella; Adducchio, Gloria; Picchia, Simona; Ralli, Eleonora; Matteucci, Eleonora; Moscarini, Massimo

2014-06-01

Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

Coffin-Siris syndrome is a multiple congenital anomaly/mental retardation syndrome with phenotypic variability [OMIM 135900]. The diagnosis is based solely on clinical findings, as there is currently no molecular, biochemical, or cytogenetic analysis available to confirm a diagnosis. Although typically described as an autosomal recessive disorder, autosomal dominant inheritance has also been infrequently reported. We describe a mother and her two daughters who all have features that resemble Coffin-Siris syndrome. However, this is not a completely convincing diagnosis given that hypertelorism is not a feature of Coffin-Siris syndrome and the family is relatively mildly affected. Yet, this family provides further evidence of an autosomal dominant mode of inheritance for a likely variant of Coffin-Siris syndrome (at least in some families). In addition, Sibling 1 had premature thelarche. She is the second reported individual within the spectrum of Coffin-Siris syndrome to have premature thelarche, indicating that it may be a rare clinical feature. Copyright 2006 Wiley-Liss, Inc.

Schinzel-Giedion syndrome is a rare recognizable malformation syndrome defined by characteristic facial features, profound developmental delay, severe growth failure, and multiple congenital anomalies. The causative gene of Schinzel-Giedion syndrome, SETBP1, has been identified, but limited cases have been confirmed by molecular analysis. We present a 9-month-old girl affected by West syndrome with Schinzel-Giedion syndrome. Congenital severe hydronephrosis, typical facial features, and multiple anomalies suggested a clinical diagnosis of Schinzel-Giedion syndrome. Hypsarrhythmia occurred at 7 months of age and was temporarily controlled by adrenocorticotropic hormone (ACTH) therapy during 5 weeks. SETBP1 mutational analysis showed the presence of a recurrent mutation, p.Ile871Thr. The implications in management of Schinzel-Giedion syndrome are discussed. © The Author(s) 2014.

2014-01-01

Iliac vein compression syndrome (also known as May-Thurner syndrome or Cockett's syndrome) is a rare clinical entity in which the left common iliac vein is compressed when it passes between the right common iliac artery and the spine. The sustained compression and trauma caused by the pulsatile force of the artery on the vein damage the intima and lead to the formation of membranes or bands in the vascular lumen that hinder or obstruct the flow of blood in the vein, favoring thrombus formation. The current treatment strategy of choice is endovascular vein patch angioplasty and stenting with the aim of improving the caliber of the lumen and enabling normal venous drainage. We present two cases of May-Thurner syndrome and review the clinical and CT findings. Copyright © 2011 SERAM. Published by Elsevier Espana. All rights reserved.

2014-12-01

The objectives were to (1) determine the frequency of specific diagnoses in a series of white lesions, and (2) describe the nature of keratotic lesions that are neither reactive nor dysplastic. White lesions were analyzed and diagnosed as reactive keratoses, dysplastic/malignant, or keratoses of unknown significance (KUS). Of the 1251 specimens that were evaluated, 703 met criteria for inclusion, and approximately 75% were reactive, 10% dysplastic/malignant, and 14% KUS. Excluding reactive keratoses, 43% were dysplastic/malignant and 57% were KUS. Reactive keratoses were the most common white lesions followed by lichen planus. Dysplastic/malignant lesions constituted almost 50% of all true leukoplakias. KUS constituted the remaining cases and do not show typical reactive histopathology as well as clear dysplasia. They may represent evolving or devolving reactive keratoses but may also represent the very earliest dysplasia phenotype. Clinical findings may be helpful in differentiating the two.

Dravet syndrome is an epileptic syndrome of infancy and early childhood. Most cases of Dravet syndrome seem to be due to a genetic defect causing the sodium channel to malfunction. We describe the main features of the syndrome. This epilepsy is medically intractable, but we call attention...... to the fact that some medications are of benefit and some could exacerbate the condition. Early recognition of the syndrome including by genetic testing could possibly improve outcome and reduce the need for other specialized investigations. Udgivelsesdato: 2010-Feb-22...

To observe clinical manifestations, behavioral characteristics, and effects of rehabilitation on a patient with pusher syndrome and unilateral spatial neglect caused by right thalamic hemorrhage. Assessment of pusher syndrome was made by the Scale for Contraversive pushing (SCP), and unilateral spatial neglect syndrome was diagnosed using line cancellation, letter and star cancellation, line bisection tests and copy and continuation of graphic sequence test. Behavioral therapy, occupational therapy, reading training and traditional Chinese medicine methods were adopted for treatment of pusher syndrome and unilateral spatial neglect. The patient showed typical pusher syndrome and unilateral spatial neglect symptoms. The pusher syndrome and unilateral spatial neglect symptoms were significantly improved following rehabilitation treatments. Pusher syndrome and unilateral spatial neglect syndrome occurred simultaneously after right thalamic hemorrhage. Early rehabilitation therapy can reduce the symptoms of pusher syndrome and unilateral spatial neglect syndrome and improve motor function.

Melanocytic nevi and non-neoplastic hyperpigmentations.

Science.gov (United States)

Clemente, C

2017-06-01

This is the first of three chapters that will be progressively published on Pathologica as updating activity of the Italian Study Group of Dermatopathology (GISD), Italian Society of Pathology and Cytology (SIAPeC IAP). The first chapter concerns non-neoplastic hyperpigmented skin lesions and nevi, the second will address the topics of dysplastic nevus, borderline and low malignant potential melanocytic proliferations and the third melanoma in its variants and differential diagnoses with a supplement on the immunohistochemistry and molecular support to diagnostic and prognostic definition of nevi and melanomas. Although we believe that great advances were made in the application of ancillary genetic, immunohistochemical and molecular techniques, for the diagnosis and biological characterization of melanocytic tumors the morphology still remains the gold standard. These chapters are not intended as substitutes or even claim to be compared to the numerous and valuable texts that are also recently published, but they want to present, concisely and quickly available, all of those traits that we believe essential to the histopathological evaluation of a melanocytic lesion. No morphological parameter is exclusive and individually sufficient to make the correct diagnosis of nevus or melanoma but to reach a final conclusive and appropriate interpretation a set of morphological characters must be evaluated and compared. I was lucky enough to be able to examine several thousand cases and to draw lessons from each of these increasing my diagnostic experience. I had a great lesson by my teacher and good friend Prof. Martin C. Mihm Jr of Boston, dermato-pathologist with undisputed international reputation, who, with great passion, patience and friendship, transferred me much of his experience and knowledge and for which I always thank him. Special thanks I would like to address Dr. Agostino Crupi, dermatologist, skin-oncologist and brilliant dermatoscopist who taught me how the

Polycystic ovary syndrome and metabolic syndrome.

Science.gov (United States)

Ali, Aus Tariq

2015-08-01

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, where the main clinical features include menstrual irregularities, sub-fertility, hyperandrogenism, and hirsutism. The prevalence of PCOS depends on ethnicity, environmental and genetic factors, as well as the criteria used to define it. On the other hand, metabolic syndrome is a constellation of metabolic disorders which include mainly abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. These associated disorders directly increase the risk of Type 2 diabetes mellitus (DMT2), coronary heart disease (CHD), cardiovascular diseases (CVD) and endometrial cancer. Many patients with PCOS have features of metabolic syndrome such as visceral obesity, hyperinsulinaemia and insulin resistance. These place patients with PCOS under high risk of developing cardiovascular disease (CVD), Type 2 diabetes (DMT2) and gynecological cancer, in particular, endometrial cancer. Metabolic syndrome is also increased in infertile women with PCOS. The aim of this review is to provide clear and up to date information about PCOS and its relationship with metabolic syndrome, and the possible interaction between different metabolic disorders.

Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

2015-01-01

Metabolic syndrome is comprised of a combination of the following states: increased insulin resistance, dyslipidemia, cardiovascular disease, and increased abdominal obesity. Women with polycystic ovary syndrome (PCOS) have an increased risk of developing metabolic syndrome over the course of their lives. Metabolic syndrome increases risk of major cardiovascular events, morbidity, quality of life, and overall health care costs. Though metabolic syndrome in women with PCOS is an area of great concern, there is no effective individual medical therapeutic to adequately treat this issue. This article will review key aspects of metabolic syndrome in PCOS. We will discuss classic and novel therapeutics to address metabolic syndrome in women with PCOS. We will conclude with the importance of developing strategic interventions to increase the compliance to lifestyle and dietary modification, in addition to appreciation of the emerging pharmaceutical therapeutics available. Innovation in lifestyle modification, including diet, exercise, with and without dedicated stress reduction techniques is the future in treatment of metabolic syndrome in PCOS. Application of novel interventions, such as group medical care, may improve future adherence to lifestyle modification recommendations, in addition to or in combination with pharmaceutical therapeutics.

Los, Evan; Baines, Hayley; Guttmann-Bauman, Ines

2017-01-01

Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome. We discuss the prevalence of delayed diagnosis of Turner syndrome, the rarity of reports of concurrent autosomal chromosome mutation and sex chromosome deletion, as well as the need to consider the diagnosis of Turner syndrome in all girls with short stature regardless of prior medical history.

Myelodysplastic syndromes and acute myeloid leukemia in cats infected with feline leukemia virus clone33 containing a unique long terminal repeat.

2009-03-01

Feline leukemia virus (FeLV) clone33 was obtained from a domestic cat with acute myeloid leukemia (AML). The long terminal repeat (LTR) of this virus, like the LTRs present in FeLV from other cats with AML, differs from the LTRs of other known FeLV in that it has 3 tandem direct 47-bp repeats in the upstream region of the enhancer (URE). Here, we injected cats with FeLV clone33 and found 41% developed myelodysplastic syndromes (MDS) characterized by peripheral blood cytopenias and dysplastic changes in the bone marrow. Some of the cats with MDS eventually developed AML. The bone marrow of the majority of cats with FeLV clone33 induced MDS produced fewer erythroid and myeloid colonies upon being cultured with erythropoietin or granulocyte-macrophage colony-stimulating factor (GM-SCF) than bone marrow from normal control cats. Furthermore, the bone marrow of some of the cats expressed high-levels of the apoptosis-related genes TNF-alpha and survivin. Analysis of the proviral sequences obtained from 13 cats with naturally occurring MDS reveal they also bear the characteristic URE repeats seen in the LTR of FeLV clone33 and other proviruses from cats with AML. Deletions and mutations within the enhancer elements are frequently observed in naturally occurring MDS as well as AML. These results suggest that FeLV variants that bear URE repeats in their LTR strongly associate with the induction of both MDS and AML in cats.

Chromosomal instability and the abrogated G2/M arrest in x-irradiated myelodysplastic syndrome cells

International Nuclear Information System (INIS)

Ban, S.; Sudo, H.; Saegusa, K.; Sagara, M.; Imai, T.; Kimura, A.

2003-01-01

A preliminary epidemiological study demonstrated that myelodysplastic syndrome (MDS) has an excess relative risk per sievert of 13 in atomic bomb survivors in Hiroshima. MDS is the only other radiogenic blood disease apart from leukemia. Clinically, MDS involves dysplastic hematopoiesis and an increased risk of leukemic transformation. Because it is uncertain whether MDS pathogenesis affects lymphoid progenitor cells as well as myeloid progenitor cells, we investigated the karyotypes of bone marrow cells and the micronucleus (MN) frequency in peripheral T lymphocytes of twenty- three atomic bomb survivors with MDS and five normal individuals. Aneuploidy was observed in 10 of 23 patients. Chromosome aberrations were observed in 3 of 12 patients with mild symptoms, and six of 11 patients of severe symptoms. The spontaneous- and X-ray-induced-MN frequencies were significantly higher in MDS patients than in normal individuals. Interestingly, radiation sensitivity increased along with the severity of MDS clinical subtypes. Because many of the patients in this study had not been exposed to chemo- or radiation- therapy, their unusual radiosensitivity may be related to their chromosomal or genomic instability. Immortalized lymphoid cell lines were established from B-lymphocytes infected with Epstein-Barr virus in vitro. The abrogation of radiation-induced-G2/M arrest was observed in 10 of 12 MDS-B lymphoid cell lines, but not in the normal B lymphoid cell lines. Our data suggest that the control of chromosomal stability is impaired in pluripotent stem cells of MDS patients, and that the abrogated G2/M arrest may be involved in the pathophysiology of disease progression and the high radiation sensitivity of patients

TAFRO syndrome is a newly recognized variant of idiopathic multicentric Castleman disease (iMCD) that involves a constellation of syndromes: thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), and organomegaly (O). Thrombocytopenia and severe anasarca accompanied by relatively low serum immunoglobulin levels are characteristic clinical findings of TAFRO syndrome that are not present in iMCD-not otherwise specified (iMCD-NOS). Lymph node biopsy is recommended to exclude other diseases and to diagnose TAFRO syndrome, which reveals characteristic histopathological findings similar to hyaline vascular-type CD. TAFRO syndrome follows a more aggressive course, compared with iMCD-NOS, and there is no standard treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

Myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN) are hematologically diverse stem cell malignancies sharing phenotypic features of both myelodysplastic syndromes and myeloproliferative neoplasms. There are currently no standard treatment recommendations for most adult patients with MDS/MPN. To optimize efforts to improve the management and disease outcomes, it is essential to identify meaningful clinical and biologic end points and standardized response criteria for clinical trials. The dual dysplastic and proliferative features in these stem cell malignancies define their uniqueness and challenges. We propose response assessment guidelines to harmonize future clinical trials with the principal objective of establishing suitable treatment algorithms. An international panel comprising laboratory and clinical experts in MDS/MPN was established involving 3 independent academic MDS/MPN workshops (March 2013, December 2013, and June 2014). These recommendations are the result of this collaborative project sponsored by the MDS Foundation. © 2015 by The American Society of Hematology.

Development and characteristics of children with Usher syndrome and CHARGE syndrome.

2012-09-01

Individuals with Usher syndrome or CHARGE syndrome are faced with a number of difficulties concerning hearing, vision, balance, and language development. The aim of the study is to describe the developmental characteristics of children with Usher syndrome and CHARGE syndrome, respectively. Data about the developmental characteristics of 26 children with Usher syndrome and 17 children with CHARGE syndrome was obtained. Associations between deafblindness (dual sensory loss), motor development (age of walking), language abilities, and intellectual outcome of these children were explored for each group independently. Both groups of children face a number of difficulties associated with vision, hearing, language, balance and intellectual outcome. Intellectual disability and/or language delay was found among 42% of the children with Usher syndrome and among 82% of the children with CHARGE syndrome. Intellectual disability was associated with language delay and age of walking for both groups. Even though Usher and CHARGE are two different genetic syndromes, both groups are challenged with a number of similar developmental delays. Clinicians need to be aware of several developmental issues in order to offer adequate support to children with Usher or CHARGE syndrome. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

2017-01-01

An increased risk of preterm birth in women with joint hypermobility syndrome or Ehlers-Danlos syndrome is suspected. In this nationwide cohort study from 1997 through 2011, women with either joint hypermobility syndrome or Ehlers-Danlos syndrome or both disorders were identified through the Swedish Patient Register, and linked to the Medical Birth Register. Thereby, 314 singleton births to women with joint hypermobility syndrome/Ehlers-Danlos syndrome before delivery were identified. These births were compared with 1 247 864 singleton births to women without a diagnosis of joint hypermobility syndrome/Ehlers-Danlos syndrome. We used logistic regression, adjusted for maternal age, smoking, parity, and year of birth, to calculate adjusted odds ratios for adverse pregnancy outcomes. Maternal joint hypermobility syndrome/Ehlers-Danlos syndrome was not associated with any of our outcomes: preterm birth (adjusted odds ratio = 0.6, 95% confidence interval 0.3-1.2), preterm premature rupture of membranes (adjusted odds ratio = 0.8; 95% confidence interval 0.3-2.2), cesarean section (adjusted odds ratio = 0.9, 95% confidence interval 0.7-1.2), stillbirth (adjusted odds ratio = 1.1, 95% confidence interval 0.2-7.9), low Apgar score (adjusted odds ratio = 1.6, 95% confidence interval 0.7-3.6), small for gestational age (adjusted odds ratio = 0.9, 95% confidence interval 0.4-1.8) or large for gestational age (adjusted odds ratio = 1.2, 95% confidence interval 0.6-2.1). Examining only women with Ehlers-Danlos syndrome (n = 62), we found a higher risk of induction of labor (adjusted odds ratio = 2.6; 95% confidence interval 1.4-4.6) and amniotomy (adjusted odds ratio = 3.8; 95% confidence interval 2.0-7.1). No excess risks for adverse pregnancy outcome were seen in joint hypermobility syndrome. Women with joint hypermobility syndrome/Ehlers-Danlos syndrome do not seem to be at increased risk of adverse pregnancy outcome. © 2016 Nordic Federation of

Wolf-Hirschhorn syndrome (WHS) is a chromosome disorder (4p-syndrome) which is characterized by craniofacial features and epileptic seizures. Here, we report a case of WHS with West syndrome, in whom the seizures were refractory to several antiepileptic drugs but were responsive to the addition of lamotrigine. The patient had epileptic spasms at age seven months. The interictal electroencephalogram was hypsarrhythmic. After adding lamotrigine, seizures decreased remarkably, and spasms disappeared. We have identified and described the very rare case of a girl with WHS who also developed West syndrome. In this case, adding lamotrigine to her medications effectively treated the spasms.

Poland's syndrome consists of the variable clinical features, but always includes unilateral aplasia of the chest wall muscles and ipsilateral anomalies of upper extremity. The incidence of Poland's syndrome, reported by different authors ranges from 1:10,000 to 1:100,000 and is observed more frequently in males than in females with the right side of the body affected more often than the left. The etiology of this syndrome is still discussed. However most of described cases were sporadic, rare familial incidence of Poland's syndrome were also presented. Therefore different etiologic factors of the Poland's syndrome are taken into account: genetic, vascular compromise during early stages of embriogenesis but also teratogenic effect of environmental xenobiotics (e.g. cigarette smoking by pregnant women). The authors present also the case of 20-years old man with inherited bilateral syndactyly with the right side aplasia of major pectoralis muscle and face asymmetry. The familial history was negative in respect to the features, associated with Poland's syndrome.

The authors present characteristics of Parental Alienation Syndrome (PAS) proposed by Gardner as well as data, which may help to differentiate that syndrome with real psychological, physical and sexual abuse. The consequences of Gardner Syndrome for legal decisions in the court cases of child custody and the critique of this syndrome in forensic and psychiatric literature are also discussed, and several questions posed. Authors propose to treat Gardner Syndrome not as as a child disorder but as a specific, dynamic family situation, which occurs sometimes, during divorce and fight about child custody.

Full Text Available El nevus sebáceo de Jadassohn (NSJ es una lesión congénita benigna pero por decenios se la consideró con alto potencial de malignización hacia el carcinoma basocelular (CBC, por lo que se sugería su resección precoz. Series recientes han establecido que muchas de las neoplasias diagnosticadas como malignas eran benignas. Nuestra revisión de 261 casos constituye un aporte al conocimiento del NSJ. Hasta ahora no ha habido series similares en Colombia, y en América Latina las publicaciones no superan los 60 pacientes. MATERIALES Y MÉTODOS: se analizaron 261 casos del archivo de histopatología de la Facultad de Medicina de la Universidad de Antioquia con diagnóstico de NSJ entre 1976 y 2008, incluyendo biopsias y resecciones. RESULTADOS: de los 261 pacientes, 143 eran hombres (54,8% y 118 mujeres (45,2%; la edad promedio fue de 17,4 años; el NSJ estaba presente al nacimiento en el 90,4%. La localización más frecuente fue en el cuero cabelludo (62,5%. Presentaron tumores asociados 28 pacientes: siringocistadenoma papilífero (SCAP 8 casos (3,1%, tumor del infundíbulo folicular (TIF 5 casos (1,9%. Cuatro casos fueron de CBC (1,5% con edad promedio de 40,7 años. Cuatro de 7 tumores diagnosticados previamente como CBC, fueron reclasificados como TIF. DISCUSIÓN: el SCAP fue el tumor más frecuentemente asociado, tal como aparece reportado por otros autores. En esta serie se encontró el TIF con una mayor frecuencia que en la literatura revisada. El CBC fue el único tumor maligno y se presentó solo en adultos. Los resultados de esta serie evidencian un comportamiento benigno del NSJ, por lo que se debiera replantear la necesidad de resección precoz. La revisión histológica del diagnóstico inicial demuestra que lesiones benignas pueden ser confundidas fácilmente con CBC, sobreestimando el potencial maligno de este hamartoma.

This study evaluates the impact in the stability and management of the marriage of parents of a child with Down or Rett Syndrome. Morbidity of the syndromes and the marital status of the couples before and after the birth of the affected children were considered variables. The divorce rate in families with Down syndrome was 10%, similar to the Brazilian rate population. In Rett Syndrome, the divorce rate was significantly higher, 23.5%. The higher morbidity of Rett Syndrome, and the moment of diagnosis could be relevant factors for the increased divorce rate related to this syndrome.

The sick-building syndrome; Das Sick-Building-Syndrom

Energy Technology Data Exchange (ETDEWEB)

Henne, A.; Neumann, H.F.; Winneke, G.

1992-12-31

The sick-building syndrome is characterized by the presence of general, non-specific symptoms (e.g., headache, tiredness, respiratory problems, eye trouble, vertigo, nausea, unspecific hypersensitivity) in association with a particular indoor ambience. It is clearly distinguishable from `building-related illness`, referring to a well-defined clinical syndrome due to staying in a building and for which a cause can, in general, be established. Disorders in the case of the sick-building syndrome are manifold and confirmed objectifiable results are hardly available so far. Yet there are some organ-related methods for the confirmation of findings concerning, for instance, the eyes, the skin and the area of the nose. The causes of the incidence of sick-building syndrome are more or less unclear. It is a multifactorial phenomenon involving physical, biological, chemical, individual-specific and psychological factors. Buildings where sick-building syndrome occurs typically exhibit certain properties. The European Community has already made proposals for the investigation of incriminated buildings. A systematic survey by questionnaire together with individual interviews plays an import part towards clarifying the syndrome. (orig./UWA) [Deutsch] Das Sick-Building-Syndrom beschreibt das Vorhandensein von allgemeinen, nicht spezifischen Symptomen (z.B. Kopfschmerzen, Muedigkeit, Atembeschwerden, Augenreizungen, Schwindelgefuehl, Uebelkeit, unspezifische Ueberempfindlichkeit), assoziiert mit einer besonderen Innenraumumgebung. Deutlich hiervon abzugrenzen ist die ``Building related illness``, bei der ein klinisch definiertes Krankheitsbild vorliegt, das durch den Aufenthalt im Gebaeude verursacht wird und fuer das im allgemeinen eine Ursache ermittelt werden kann. Das Beschwerdebild beim Sick-Building-Syndrom ist vielfaeltig, und gesicherte, objektivierbare Befunde liegen hierzu bisher kaum vor. Dennoch gibt es einige organbezogenen Methoden zur Befundabsicherung, z.B. fuer das

Syndromes with supernumerary teeth.

Science.gov (United States)

Lubinsky, Mark; Kantaputra, Piranit Nik

2016-10-01

While most supernumerary teeth are idiopathic, they can be associated with a number of Mendelian syndromes. However, this can also be a coincidental finding, since supernumerary teeth occur in 6% or more of the normal population. To better define this relationship, we analyzed the evidence for specific associations. We excluded conditions with a single affected patient reported, supernumerary teeth adjacent to clefts or other forms of alveolar disruption (as secondary rather than primary findings), and natal teeth, which can involve premature eruption of a normal tooth. Since, the cause of supernumerary teeth shows considerable heterogeneity, certain findings are less likely to be coincidental, such as five or more supernumerary teeth in a single patient, or locations outside of the premaxilla. We found only eight genetic syndromes with strong evidence for an association: cleidocranial dysplasia; familial adenomatous polyposis; trichorhinophalangeal syndrome, type I; Rubinstein-Taybi syndrome; Nance-Horan syndrome; Opitz BBB/G syndrome; oculofaciocardiodental syndrome; and autosomal dominant Robinow syndrome. There is also suggestive evidence of an association with two uncommon disorders, Kreiborg-Pakistani syndrome (craniosynostosis and dental anomalies), and insulin-resistant diabetes mellitus with acanthosisnigricans. An association of a Mendelian disorder with a low frequency manifestation of supernumerary teeth is difficult to exclude without large numbers, but several commonly cited syndromes lacked evidence for clear association, including Hallermann-Streiff syndrome, Fabry disease, Ehlers-Danlos syndrome, Apert and Crouzon syndromes, Zimmermann-Laband syndrome, and Ellis-van Creveld syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Yu-Feng Huang

2010-09-01

Full Text Available Nevoid basal cell carcinoma syndrome (also named Gorlin-Goltz syndrome is a rare disease. Commonly seen features include multiple odontogenic keratocysts (OKCs, nevus-like basal cell carcinoma, and bifid ribs. Genetic alterations of the PTCH1 gene are associated with the disease. Herein, we report the case of a 15-year-old girl who presented with multiple OKCs, a bifid rib, ectopic calcification of the falx cer-ebri, and an arachnoid cyst of the cerebrum. No basal cell carcinoma was identified. In addition, a search for genetic alterations was performed on the patient. We identified a genetic mutation of C→T in exon 12 (c.1686 bp and a G→C mutation in intron 13 (g.91665 bp of the PTCH1 gene. Although a similar mutation in exon 12 was reported in a literature search, the mutation in intron 13 has not previously been reported. The patient has continued to be followed-up almost 3 years after the surgery with no recurrence of the OKCs or development of basal cell carcinoma.

Autoimmune/inflammatory syndrome induced by adjuvants (Shoenfeld's syndrome) - An update.

Watad, A; Quaresma, M; Brown, S; Cohen Tervaert, J W; Rodríguez-Pint, I; Cervera, R; Perricone, C; Shoenfeld, Y

2017-06-01

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) has been widely described in many studies conducted thus far. The syndrome incorporates five immune-mediated conditions, all associated with previous exposure to various agents such as vaccines, silicone implants and several others. The emergence of ASIA syndrome is associated with individual genetic predisposition, for instance those carrying HLA-DRB1*01 or HLA-DRB4 and results from exposure to external or endogenous factors triggering autoimmunity. Such factors have been demonstrated as able to induce autoimmunity in both animal models and humans via a variety of proposed mechanisms. In recent years, physicians have become more aware of the existence of ASIA syndrome and the relationship between adjuvants exposure and autoimmunity and more cases are being reported. Accordingly, we have created a registry that includes at present more than 300 ASIA syndrome cases that have been reported by different physicians worldwide, describing various autoimmune conditions induced by diverse adjuvants. In this review, we have summarized the updated literature on ASIA syndrome and the knowledge accumulated since 2013 in order to elucidate the association between the exposure to various adjuvant agents and its possible clinical manifestations. Furthermore, we especially referred to the relationship between ASIA syndrome and systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS).

Eosinophilic leukocytoclastic vasculitis - a spectrum ranging from Wells' syndrome to Churg-Strauss syndrome?

Science.gov (United States)

Ratzinger, Gudrun; Zankl, Julia; Eisendle, Klaus; Zelger, Bernhard

2014-01-01

Wells' syndrome is defined as an inflammatory disorder with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Eosinophilic leukocytoclastic vasculitis shows eosinophilic infiltrates in combination with vasculitic changes. And Churg Strauss Syndrome comprises all three characteristics - eosinophilic infiltrates, vasculitis and flame figures. To determine whether these three diseases are distinct entities or different manifestations of a similar clinicopathologic process. Histopathological samples and clinical courses of 17 patients with eosinophilic infiltrates, flame figures and clinical features of Wells' syndrome were re-evaluated. Histopathologically, we focused on the presence or absence of vasculitic features. Clinically, we included only patients who were diagnosed with Wells' syndrome at least once in the course of their disease. 4 patients were finally diagnosed with Wells' syndrome, 5 with eosinophilic leukocytoclastic vasculitis and 6 with Churg Strauss syndrome. Further, we had one case of an overlap between Wells' syndrome and eosinophilic vasculitis and one case of Wegener granulomatosis. Vasculitic features were found in the samples of all patients. Histologically, we find vasculitic features in typical presentations of Wells' syndrome. Clinically, we find typical features of Wells' syndrome in patients finally diagnosed with eosinophilic leukocytoclastic vasculitis or Churg Strauss syndrome. Furthermore, we have observed and formerly reported 3 patients with progression from Wells' syndrome to Churg Strauss syndrome. Thus, we assume that eosinophilic leukocytoclastic vasculitis might form a bridge between Wells' syndrome and Churg Strauss syndrome.

Management of moyamoya syndrome in patients with Noonan syndrome.

Gupta, Mihir; Choudhri, Omar A; Feroze, Abdullah H; Do, Huy M; Grant, Gerald A; Steinberg, Gary K

2016-06-01

A few isolated reports have described an association between Noonan syndrome and cerebrovascular abnormalities, including moyamoya syndrome. These reports have been limited to pediatric patients presenting with recurrent transient ischemic attacks (TIA) or headaches. Management has primarily been pharmacologic, with only one prior report of surgical revascularization to our knowledge. We report four cases of Noonan syndrome patients presenting with headaches and/or sensorimotor strokes in childhood that caused unilateral sensorimotor impairment. Cerebral angiography and MRI revealed bilateral moyamoya syndrome. All patients underwent successful bilateral extracranial-to-intracranial revascularization. The first patient was a 10-year-old girl who presented following a hemorrhagic stroke and recovered well after indirect bypass. The second patient was an adult with a history of childhood stroke whose symptoms progressed in adulthood. She underwent a direct bypass and improved, but continued to experience TIA at her 4 year follow-up. The third patient was a 7-year-old girl with headaches and a new onset TIA who failed pharmacological therapy and subsequently underwent bilateral indirect bypass. The fourth patient was a 24-year-old woman with worsening headaches and an occluded left middle cerebral artery from unilateral moyamoya syndrome. A left sided direct bypass was completed given delayed MRI perfusion with poor augmentation. To our knowledge these are the first reported surgical cases of combined Noonan and moyamoya syndrome. These cases highlight the need to recognize moyamoya syndrome in patients with Noonan syndrome. Early surgical revascularization should be pursued in order to prevent symptom progression.

Full Text Available Gorlin-Goltz syndrome also known as nevoid basal cell carcinoma syndrome (NBCCS is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by keratocystic odontogenic tumors (KCOT in the jaw, multiple basal cell carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic examination in the first decade of life, as KCOTs are usually one of the first manifestations of the NBCCS syndrome. This article reports the case of a 12-year-old girl with Gorlin-Goltz syndrome, emphasizing its clinical and radiographic manifestation. This study highlights the importance of health professionals in the early diagnosis of this syndrome and a multidisciplinary approach to provide a better diagnosis and prognosis.

Bardet-Biedl syndrome and Usher syndrome.

Science.gov (United States)

Koenig, Rainer

2003-01-01

Bardet-Biedl syndrome (BBS) and Usher syndrome (USH) are the most prevalent syndromic forms of retinitis pigmentosa (RP), together they make up almost a quarter of the patients with RP. BBS is defined by the association of retinopathy, obesity, hypogonadism, renal dysfunction, postaxial polydactyly and mental retardation. This clinically complex syndrome is genetically heterogeneous with linkage to more than 6 loci, and 4 genes have been cloned so far. Recent molecular data present evidence that, in some instances, the clinical manifestation of BBS requires recessive mutations in 1 of the 6 BBS loci plus one or two additional mutations in a second BBS locus (tri- or tetra-allelic inheritance). USH is characterized by the combination of congenital or early-onset sensorineural deafness, RP, and variable degrees of vestibular dysfunction. Each of the three clinical types is genetically heterogeneous: 7 loci have been mapped for type 1, three loci for type 2, and two loci for type 3. Currently, 6 USH genes (MYO7A, USH1C, CDH23, PCDH15, USH2A, USH3) have been identified. Pathogenetically, mutations of the USH1 genes seem to result in defects of auditory and retinal sensory cells, the USH 2 phenotype is caused by defects of extracellular matrix or cell surface receptor proteins, and USH3 may be due to synaptic disturbances. The considerable contribution of syndromic forms of RP requires interdisciplinary approaches to the clinical and diagnostic management of RP patients.

Munchausen syndrome and Munchausen syndrome by proxy in dermatology.

Science.gov (United States)

Boyd, Alan S; Ritchie, Coleman; Likhari, Sunaina

2014-08-01

Patients with Munchausen syndrome purposefully injure themselves, often with the injection of foreign materials, to gain hospital admission and the attention associated with having a difficult-to-identify condition. Munchausen syndrome by proxy occurs when a child's caregiver, typically the mother, injures the child for the same reasons. Cases of Munchausen syndrome and Munchausen syndrome by proxy with primary cutaneous involvement appear to be rarely described in the literature suggesting either that diagnosis is not made readily or that it is, in fact, an uncommon disorder. At the center of both conditions is significant psychological pathology and treatment is difficult as many patients with Munchausen syndrome when confronted with these diagnostic possibilities simply leave the hospital. Little is known about the long-term outcome or prognosis of these patients. Copyright © 2014 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

Redefining syndromic surveillance

Directory of Open Access Journals (Sweden)

Rebecca Katz

2011-12-01

Full Text Available With growing concerns about international spread of disease and expanding use of early disease detection surveillance methods, the field of syndromic surveillance has received increased attention over the last decade. The purpose of this article is to clarify the various meanings that have been assigned to the term syndromic surveillance and to propose a refined categorization of the characteristics of these systems. Existing literature and conference proceedings were examined on syndromic surveillance from 1998 to 2010, focusing on low- and middle-income settings. Based on the 36 unique definitions of syndromic surveillance found in the literature, five commonly accepted principles of syndromic surveillance systems were identified, as well as two fundamental categories: specific and non-specific disease detection. Ultimately, the proposed categorization of syndromic surveillance distinguishes between systems that focus on detecting defined syndromes or outcomes of interest and those that aim to uncover non-specific trends that suggest an outbreak may be occurring. By providing an accurate and comprehensive picture of this field’s capabilities, and differentiating among system types, a unified understanding of the syndromic surveillance field can be developed, encouraging the adoption, investment in, and implementation of these systems in settings that need bolstered surveillance capacity, particularly low- and middle-income countries.

Lhermitte-Duclos disease with neurofibrillary tangles in heterotopic cerebral grey matter

Directory of Open Access Journals (Sweden)

Daniel Rusiecki

2016-06-01

Full Text Available Lhermitte-Duclos disease (LDD, a disorder first described by French physicians Lhermitte and Duclos in 1920 [25], is a benign, slow growing dysplastic gangliocytoma of the cerebellum, characterized by replacement of the granule cell layer by abnormal granule and Purkinje like cells. The most frequent presenting signs and symptoms are megalocephaly, increased intracranial pressure, nausea, hydrocephalus, ataxia, gait abnormalities, and intermittent headaches, all of which are attributed to the mass effect [6,11,25]. Many cases are associated with a mutation in the phosphatase and tensin homolog or PTEN gene which is also involved in numerous otherwise unrelated central nervous system abnormalities, namely Cowden syndrome [1,6,11], autism spectrum disorder [18], cerebral cortical dysplasia [11,30] and Bannayan-Riley-Ruvalcaba syndrome [30]. The presence of cortical heterotopia has been reported in a small number of LDD cases [3,5,17,32]. We describe a unique case of LDD with cerebral cortical heterotopic grey matter containing neurofibrillary tangles.

The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

Synonyms for the `battered child` syndrome (BCS) are terms describing the physical and body aspects of the process, such as `child abuse`, or `non-accidental injury`. These are to be distinguished from the psychic aspects and abuse, emotional and bodily neglect, and sexual abuse. Most cases are one or another combination of these aspects. Radiology is the essential method for giving proof of such abuses, identifying the signs of maltreatment in a medical record, or for disproving suspected abuse. (orig./AJ) [Deutsch] Als Synonym fuer das `Battered-Child`-Syndrom (BCS) stehen die Begriffe der koerperlichen-/physikalischen-Kindesmisshandlung, im angelsaechsischen Sprachraum die Begriffe `Child Abuse` und `Nonaccidental Injury`. Vom Syndrom abzugrenzen sind die seelische Misshandlung, die seelische und koerperliche Vernachlaessigung, und der sexuelle Missbrauch. Kombinationsformen sind nicht selten. Bei der Diagnostik des Syndroms spielt die Radiologie eine entscheidende Rolle. So hilft der Einsatz adaequater Untersuchungsmethoden, den Tatbestand der Misshandlung zu identifizieren und zu dokumentieren, aber auch einen Verdacht zu widerlegen. (orig./AJ)

Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

DEPDC5 is a newly identified epilepsy-related gene implicated in focal epilepsy, brain malformations, and Sudden Unexplained Death in Epilepsy (SUDEP). In vitro, DEPDC5 negatively regulates amino acid sensing by the mTOR complex 1 (mTORC1) pathway, but the role of DEPDC5 in neurodevelopment and epilepsy has not been described. No animal model of DEPDC5-related epilepsy has recapitulated the neurological phenotypes seen in patients, and germline knockout rodent models are embryonic lethal. Here, we establish a neuron-specific Depdc5 conditional knockout mouse by cre-recombination under the Synapsin1 promotor. Depdc5 flox/flox -Syn1 Cre (Depdc5cc+) mice survive to adulthood with a progressive neurologic phenotype that includes motor abnormalities (i.e., hind limb clasping) and reduced survival compared to littermate control mice. Depdc5cc+ mice have larger brains with increased cortical neuron size and dysplastic neurons throughout the cortex, comparable to the abnormal neurons seen in human focal cortical dysplasia specimens. Depdc5 results in constitutive mTORC1 hyperactivation exclusively in neurons as measured by the increased phosphorylation of the downstream ribosomal protein S6. Despite a lack of increased mTORC1 signaling within astrocytes, Depdc5cc+ brains show reactive astrogliosis. We observed two Depdc5cc+ mice to have spontaneous seizures, including a terminal seizure. We demonstrate that as a group Depdc5cc+ mice have lowered seizure thresholds, as evidenced by decreased latency to seizures after chemoconvulsant injection and increased mortality from pentylenetetrazole-induced seizures. In summary, our neuron-specific Depdc5 knockout mouse model recapitulates clinical, pathological, and biochemical features of human DEPDC5-related epilepsy and brain malformations. We thereby present an important model in which to study targeted therapeutic strategies for DEPDC5-related conditions. Copyright © 2017 Elsevier Inc. All rights reserved.

The Capgras syndrome is one of delusional-like misidentification syndrome in which a person holds a delusion that one or several his/her friends or relatives have been replaced by an identical-looking impostor. As any other delusional disorder, the Capgras syndrome is characterized by stability despite the indisputable arguments against fault views. Initially, this syndrome was considered as a presentation of schizophrenia but later it has been described in brain organic disorders, primarily in elderly patients with dementia.

A Case Report: Nager Acrofacial Dysostosis

Directory of Open Access Journals (Sweden)

Shahin Abdollahi Fakhim

2012-01-01

Full Text Available Introduction: Nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. The cause of the abnormal development of the pharyngeal arches in Nager syndrome is unknown. It is also unclear why affected individuals have bone abnormalities in their arms and legs. Nager syndrome is thought to have an autosomal recessive inheritance pattern when unaffected parents have more than one affected child. The purpose of this report is to present a case of Nager syndrome where the patient exhibited upper limb shortening, an unusual feature that has been reported as coexisting in some individuals with Nager syndrome.  Case report: A 3.5-year-old girl was referred to our Department of Pediatric Otorhinolaryngology due to a cleft palate. Her craniofacial anomalies included malar hypoplasia, severe mandibular hypoplasia with retrognathia, downward slanted palpebral fissures, a high narrow hard palate, absent soft palate, small retroplaced tongue, bilateral external auditory canal atresia, and dysplastic ears. There was no evidence of mental retardation. Based on the craniofacial characteristics and the coexisting upper limb preaxial anomalies, a diagnosis of Nager syndrome was confirmed.  Conclusion: Nager syndrome is a rare disorder resulting from developmental abnormalities of the first and second branchial arches. It is linked to five other similar syndromes: Miller syndrome, Treacher-Collins, Pierre-Robin, Genee-Wiedemann, and Franceschetti-Zwahlen-Klein. Multidisciplinary management by a craniofacial team is needed. Early intervention, intensive education, new surgical techniques, and an emphasis on coordinated care have improved the quality of life in this patient with Nager syndrome.

2006-09-01

Full Text Available Abstract Plummer-Vinson or Paterson-Kelly syndrome presents as a classical triad of dysphagia, iron-deficiency anemia and esophageal webs. Exact data about epidemiology of the syndrome are not available; the syndrome is extremely rare. Most of the patients are white middle-aged women, in the fourth to seventh decade of life but the syndrome has also been described in children and adolescents. The dysphagia is usually painless and intermittent or progressive over years, limited to solids and sometimes associated with weight loss. Symptoms resulting from anemia (weakness, pallor, fatigue, tachycardia may dominate the clinical picture. Additional features are glossitis, angular cheilitis and koilonychia. Enlargement of the spleen and thyroid may also be observed. One of the most important clinical aspects of Plummer-Vinson syndrome is the association with upper alimentary tract cancers. Etiopathogenesis of Plummer-Vinson syndrome is unknown. The most important possible etiological factor is iron deficiency. Other possible factors include malnutrition, genetic predisposition or autoimmune processes. Plummer-Vinson syndrome can be treated effectively with iron supplementation and mechanical dilation. In case of significant obstruction of the esophageal lumen by esophageal web and persistent dysphagia despite iron supplementation, rupture and dilation of the web are necessary. Since Plummer-Vinson syndrome is associated with an increased risk of squamous cell carcinoma of the pharynx and the esophagus, the patients should be followed closely.

Wolfram syndrome 1 and Wolfram syndrome 2.

Rigoli, Luciana; Di Bella, Chiara

2012-08-01

Wolfram syndrome 1 (WS1) is an autosomal recessive disorder characterized by diabetes insipidus, diabetes mellitus, optic atrophy, and deafness (DI DM OA D syndrome) associated with other variable clinical manifestations. The causative gene for WS1 (WFS1) encoding wolframin maps to chromosome 4p16.1. Wolframin has an important function in maintaining the homeostasis of the endoplasmic reticulum (ER) in pancreatic β cells. Recently, another causative gene, CISD2, has been identified in patients with a type of Wolfram syndrome (WS2) resulting in early optic atrophy, diabetes mellitus, deafness, decreased lifespan, but not diabetes insipidus. The CISD2-encoded protein ERIS (endoplasmic reticulum intermembrane small protein) also localizes to ER, but does not interact directly with wolframin. ERIS maps to chromosome 4q22. Numerous studies have shown an interesting similarity between WFS1 and CISD2 genes. Experimental studies demonstrated that the Cisd2 knockout (Cisd2) mouse shows premature aging and typical symptoms of Wolfram syndrome. These researches provide interesting insight into the relation of neurodegenerative diseases, mitochondrial disorders, and autophagy and are useful for the pathophysiological understanding of both Wolfram syndrome and mitochondrial-mediated premature aging. The knowledge of WS1 and WS2 pathogenesis, and of the interactions between WFS1 and CISD2 genes, is useful for accurate diagnostic classification and for diagnosis of presymptomatic individuals.

Full Text Available Background: Treacher-Collins syndrome is a congenital craniofacial disorder with multiple anomalies. This syndrome affects the maxilla, mandible, eyes, middle and outer ears, and soft palate. Conductive hearing loss due to the deformities of the middle and external ears is prevalent. The characteristics of this syndrome include multiple and serious threats to normal communication development in children. In this study, speech and language features of a Persian speaking child with this syndrome are presented.Case: The case was an 8-year old girl with Treacher-Collins syndrome and bilateral moderate conductive hearing loss due to atretic canal. In language and speech assessments, moderate hypernasality, numerous compensatory errors and morphosyntactic deficits were observed. There were 13 phonemes that were incorrectly produced at least in one position. Besides, she used 22 types of phonological processes that were abnormal and disappear before the age of three in normal Persian speaking children.Conclusion: Moderate hearing loss, velopharyngeal incompetency, malocclusion and dental anomalies, attention deficit/hyperactivity disorder (ADHD and environmental factors resulted in severe speech and language disorders in this case. These disorders affected her academic performance as well. Moderate hypernasality, numerous compensatory errors, and excessive and abnormal use of phonological processes were not presented as prevalent characteristics of Treacher-Collins syndrome in other resources.

2013-01-01

Some headache syndromes have few cases reported in the literature. Their clinical characteristics, pathogenesis, and treatment may have not been completely defined. They may not actually be uncommon but rather under-recognized and/or underreported. A literature review of unusual headache syndromes, searching PubMed and ISI Web of Knowledge, was performed. After deciding which disorders to study, relevant publications in scientific journals, including original articles, reviews, meeting abstracts, and letters or correspondences to the editors were searched. This paper reviewed the clinical characteristics, the pathogenesis, the diagnosis, and the treatment of five interesting and unusual headache syndromes: exploding head syndrome, red ear syndrome, neck-tongue syndrome, nummular headache, and cardiac cephalgia. Recognizing some unusual headaches, either primary or secondary, may be a challenge for many non-headache specialist physicians. It is important to study them because the correct diagnosis may result in specific treatments that may improve the quality of life of these patients, and this can even be life saving. © 2013 American Headache Society.

In dermatology, photographic imagery is acquired in large volumes in order to monitor the progress of diseases, especially melanocytic skin cancers. For this purpose, overview (macro) images are taken of the region of interest and used as a reference map to re-localize highly magni ed images of individual lesions. The latter are then used for diagnosis. These pictures are acquired at irregular intervals under only partially constrained circumstances, where patient positions as well as camera positions are not reliable. In the presence of a large number of nevi, correct identi cation of the same nevus in a series of such images is thus a time consuming task with ample chances for error. This paper introduces a method for largely automatic and simultaneous identi cation of nevi in di erent images, thus allowing the tracking of a single nevus over time, as well as pattern evaluation. The method uses a rotation-invariant feature descriptor that uses the local neighborhood of a nevus to describe it. The texture, size and shape of the nevus are not used to describe it, as these can change over time, especially in the case of a malignancy. We then use the Random Walks framework to compute the correspondences based on the probabilities derived from comparing the feature vectors. Evaluation is performed on synthetic and patient data at the university clinic.

Does wastewater discharge have relations with increase of Turner syndrome and Down syndrome?

Science.gov (United States)

Choi, Intae

2017-01-01

The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on Korea's metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution. Air pollutants did not have a significant impact on the number of Turner syndrome and Down syndrome cases; however, the increase in number of wastewater discharge companies did have a significant relationship with the number of cases. The more the number of wastewater discharge companies, the more the number Turner syndrome and Down syndrome cases were observed. Therefore, scientific investigation on water and air pollutants in relation with genetic health effects needs to be performed.

Full Text Available Abstract Introduction We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. Case presentation A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized hypertrichosis, and hypoplastic fifth fingernails and toenails. A thorough medical examination and evaluation revealed she had phenotypic features of Coffin-Siris syndrome, with Mayer-Rokitansky-Küster-Hauser syndrome on radiological evaluation. The karyotype of our patient was normal. Conclusion In an unexplained case of mental retardation with facies suggestive of Coffin-Siris syndrome, association with Mayer-Rokitansky-Küster-Hauser syndrome should be considered and the patient should be evaluated for the same. Both of these syndromes may have a common pathogenesis, as yet unknown. This case report has broad implications, as similar cases in future may give insights into the pathogenesis of both these syndromes.

Vários fatores clínicos e laboratoriais foram analisados como prognósticos. O objetivo dessa revisão é analisar os sistemas prognósticos avaliando sobrevida global e abordagem terapêutica. A avaliação do sistema WPSS, que alia grupos de riscos citogenéticos e a presença ou não de dependência transfusional define cinco grupos de riscos com diferença estatística em termos de sobrevida global e risco de transformação leucêmica. A proposta formulada é a avaliação do sistema WPSS como sistema prognóstico capaz de substituir o IPSS a fim de melhor definir os grupos de risco e diferentes abordagens terapêuticas.The myelodysplastic syndromes represent a heterogeneous group of haematopoietic disorders characterized by ineffective haematopoiesis, peripheral cytopenias, hypercellular bone marrow and dysplastic haematopoiesis. Several laboratory and clinical features have been analysed as prognostic factors. The aim of this review is to evaluate the prognostic scoring systems focusing on overall survival and therapeutic approach. The WPSS evaluation includes both cytogenetic risk groups and transfusional necessities. It has five well-defined risk groups with statistical divergences related to overall survival and leukemic transformation risk. Our proposal is to evaluate the WPSS as a prognostic scoring system able to replace the IPSS, in order to establish a better definition of the risk groups and the different therapeutic approaches.

Developmental tumors and adjacent cortical dysplasia: single or dual pathology?

Science.gov (United States)

Palmini, André; Paglioli, Eliseu; Silva, Vinicius Duval

2013-12-01

Developmental tumors often lead to refractory partial seizures and constitute a well-defined, surgically remediable epilepsy syndrome. Dysplastic features are often associated with these tumors, and their significance carries both practical and conceptual relevance. If associated focal cortical dysplasia (FCD) relates to the extent of the epileptogenic tissue, then presurgical evaluation and surgical strategies should target both the tumor and the surrounding dyslaminated cortex. Furthermore, the association has been included in the recently revised classification of FCD and the epileptogenicity of this associated dysplastic tissue is crucial to validate such revision. In addition to the possibility of representing dual pathology, the association of developmental tumors and adjacent dysplasia may instead represent a single developmental lesion with distinct parts distributed along a histopathologic continuum. Moreover, the possibility that this adjacent dyslamination is of minor epileptogenic relevance should also be entertained. Surgical data show that complete resection of the solid tumors and immediately adjacent tissue harboring satellites may disrupt epileptogenic networks and lead to high rates of seizure freedom, challenging the epileptogenic relevance of more extensive adjacent dyslaminated cortex. Whether the latter is a primary or secondary abnormality and whether dyslaminated cortex in the context of a second lesion may produce seizures after complete resection of the main lesion is still to be proven.

Association between melanocytic neoplasms and seborrheic keratosis: more than a coincidental collision?

Science.gov (United States)

DeFazio, Jennifer; Zalaudek, Iris; Busam, Klaus J.; Cota, Carlo; Marghoob, Ashfaq

2012-01-01

Clinical observations and an expanding knowledge of cell-to-cell communication have led us to speculate that the finding of a melanocytic nevus in conjunction with a seborrheic keratosis is more than a coincidental collision of two lesions. Here we present five cases demonstrating dermoscopic features of both melanocytic lesions and seborrheic keratoses with corresponding histology. Four cases demonstrate dermoscopic features of a melanocytic nevus and seborrheic keratosis, and the final case a melanoma arising in association with a seborrheic keratosis. PMID:23785597

Chronic exertional compartment syndrome with medial tibial stress syndrome in twins.

Banerjee, Purnajyoti; McLean, Christopher

Chronic exertional compartment syndrome and medial tibial stress syndrome are uncommon conditions that affect long-distance runners or players involved in team sports that require extensive running. We report 2 cases of bilateral chronic exertional compartment syndrome, with medial tibial stress syndrome in identical twins diagnosed with the use of a Kodiag monitor (B. Braun Medical, Sheffield, United Kingdom) fulfilling the modified diagnostic criteria for chronic exertional compartment syndrome as described by Pedowitz et al, which includes: (1) pre-exercise compartment pressure level >15 mm Hg; (2) 1 minute post-exercise pressure >30 mm Hg; and (3) 5 minutes post-exercise pressure >20 mm Hg in the presence of clinical features. Both patients were treated with bilateral anterior fasciotomies through minimal incision and deep posterior fasciotomies with tibial periosteal stripping performed through longer anteromedial incisions under direct vision followed by intensive physiotherapy resulting in complete symptomatic recovery. The etiology of chronic exertional compartment syndrome is not fully understood, but it is postulated abnormal increases in intramuscular pressure during exercise impair local perfusion, causing ischemic muscle pain. No familial predisposition has been reported to date. However, some authors have found that no significant difference exists in the relative perfusion, in patients, diagnosed with chronic exertional compartment syndrome. Magnetic resonance images of affected compartments have indicated that the pain is not due to ischemia, but rather from a disproportionate oxygen supply versus demand. We believe this is the first report of chronic exertional compartment syndrome with medial tibial stress syndrome in twins, raising the question of whether there is a genetic predisposition to the causation of these conditions.

Noonan-like syndrome with loose anagen hair is one of the RASopathies characterized by Noonan syndrome-like features with unique ectodermal abnormalities. This syndrome is caused by mutations in the SHOC2 gene. We encountered a patient with moyamoya syndrome associated with Noonan-like syndrome with loose anagen hair presenting with transient ischemic attacks. A 6-year-old girl was diagnosed with Noonan-like syndrome with loose anagen hair because of profound short stature and ectodermal anomalies such as sparse and easily pluckable hair. A heterozygous mutation of c.4A>G (p.S2G) in the SHOC2 gene was identified, and recombinant human growth hormone therapy was initiated at 8 years of age. At age 10, she manifested recurrent left hemiplegia. Moreover, cerebrovascular imaging revealed occlusion or narrowing of both internal carotid arteries and both middle cerebral arteries with distal moyamoya-like vessels. She is treated with aspirin and calcium channel blocker. We describe the first case of Noonan-like syndrome with loose anagen hair associated with moyamoya syndrome, although it has been reported to be associated with a few cases of other RASopathies, including Noonan, cardiofaciocutaneous, and Costello syndromes. This report emphasizes the associations between cerebrovascular anomalies and Noonan-like syndrome with loose anagen hair. Copyright © 2015 Elsevier Inc. All rights reserved.

Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

Two pairs of siblings are described with proportionate dwarfism due to skeletal hypoplasia of prenatal onset. The head size was normal for age and disproportionately large for height. The patients had a characteristic face different from that seen in the Silver-Russell syndrome. The family data are in accordance with autosomal recessive inheritance. In spite of some similarities, the bulk of clinical and genetic evidence suggests that the described intrauterine growth retardation syndrome is different from the Silver-Russell syndrome and presents an apparently "new" entity which has been designated 3-M syndrome.

Are ECG abnormalities in Noonan syndrome characteristic for the syndrome?

Raaijmakers, R; Noordam, C; Noonan, J A; Croonen, E A; van der Burgt, C J A M; Draaisma, J M T

2008-12-01

Of all patients with Noonan syndrome, 50-90% have one or more congenital heart defects. The most frequent occurring are pulmonary stenosis (PS) and hypertrophic cardiomyopathy. The electrocardiogram (ECG) of a patient with Noonan syndrome often shows a characteristic pattern, with a left axis deviation, abnormal R/S ratio over the left precordium, and an abnormal Q wave. The objective of this study was to determine if these ECG characteristics are an independent feature of the Noonan syndrome or if they are related to the congenital heart defect. A cohort study was performed with 118 patients from two university hospitals in the United States and in The Netherlands. All patients were diagnosed with definite Noonan syndrome and had had an ECG and echocardiography. Sixty-nine patients (58%) had characteristic abnormalities of the ECG. In the patient group without a cardiac defect (n = 21), ten patients had a characteristic ECG abnormality. There was no statistical relationship between the presence of a characteristic ECG abnormality and the presence of a cardiac defect (p = 0.33). Patients with hypertrophic cardiomyopathy had more ECG abnormalities in total (p = 0.05), without correlation with a specific ECG abnormality. We conclude that the ECG features in patients with Noonan syndrome are characteristic for the syndrome and are not related to a specific cardiac defect. An ECG is very useful in the diagnosis of Noonan syndrome; every child with a Noonan phenotype should have an ECG and echocardiogram for evaluation.

Our objective is to stress the importance of the radiological findings, which in many cases are decisive in establishing the definitive diagnosis. (Author) 10 refs

Does wastewater discharge have relations with increase of Turner syndrome and Down syndrome?

Directory of Open Access Journals (Sweden)

Intae Choi

2017-08-01

Full Text Available The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on Korea’s metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution. Air pollutants did not have a significant impact on the number of Turner syndrome and Down syndrome cases; however, the increase in number of wastewater discharge companies did have a significant relationship with the number of cases. The more the number of wastewater discharge companies, the more the number Turner syndrome and Down syndrome cases were observed. Therefore, scientific investigation on water and air pollutants in relation with genetic health effects needs to be performed.

Full Text Available In this paper the development of a new internet information system for analyzing and classifying melanocytic dat, is briefly described. This system also has some teaching functions, improves the analysis of datasets based on calculating the values of the TDS (Total Dermatoscopy Score (Braun-Falco, Stolz, Bilek, Merkle, & Landthaler, 1990; Hippe, Bajcar, Blajdo, Grzymala-Busse, Grzymala-Busse, & Knap, et al., 2003 parameter. Calculations are based on two methods: the classical ABCD formula (Braun-Falco et al., 1990 and the optimized ABCD formula (Alvarez, Bajcar, Brown, Grzymala-Busse, & Hippe, 2003. A third method of classification is devoted to quasi-optimal decision trees (Quinlan, 1993. The developed internet-based tool enables users to make an early, non-invasive diagnosis of melanocytic lesions. This is possible using a built-in set of instructions that animates the diagnosis of the four basic lesions types: benign nevus, blue nevus, suspicious nevus and melanoma malignant.

2012-01-01

The skin, hair and nail changes in four distinct ectodermal dysplasia syndromes are compared and reviewed. These syndromes comprise Christ-Siemens-Touraine syndrome; ectrodactyly, ectodermal dysplasia and cleft lip/palate syndrome; ankyloblepharon-ectodermal defects-cleft lip/palate syndrome and Rapp-Hodgkin syndrome. A comprehensive overview of the dermatological signs and symptoms in these syndromes was generated from the database of the Ectodermal Dysplasia Network Germany, the clinical findings in the patients seen in our department and an extensive review of the literature. The findings included abnormalities of skin, sweating, hair and nails. These clinical findings are discussed in relation to the underlying molecular defects known to play a role in these four ectodermal dysplasia syndromes.

2018-03-05

To review the association between orthostatic intolerance syndromes and both joint hypermobility and Ehlers-Danlos syndrome, and to propose reasons for identifying hereditary connective tissue disorders in those with orthostatic intolerance in the context of both clinical care and research. We searched the published peer-reviewed medical literature for papers reporting an association between joint hypermobility or Ehlers-Danlos syndrome and orthostatic intolerance. We identified 10 relevant papers. Although methodological variability between studies introduces some limitations, the published literature consistently identifies a significantly higher prevalence of orthostatic intolerance symptoms in patients with joint hypermobility or Ehlers-Danlos syndrome than in healthy controls, and a significantly higher prevalence of cardiovascular and autonomic abnormalities both at rest and during orthostatic challenge. Postural tachycardia syndrome is the most commonly recognized circulatory disorder. The severity of orthostatic symptoms in those with EDS correlates with impairments in quality of life. There is a strong association between several forms of cardiovascular dysfunction, most notably postural tachycardia syndrome, and joint hypermobility or Ehlers-Danlos syndrome. We propose that recognition of joint hypermobility and Ehlers-Danlos syndrome among those with orthostatic intolerance syndromes has the potential to improve clinical care and the validity of research findings.

CHAND syndrome is an autosomal recessive disorder characterized by curly hair, ankyloblepharon, and nail dysplasia. Only few patients were reported to date. A homozygous RIPK4 mutation was recently identified by homozygosity mapping and whole exome sequencing in three patients from an expanded consanguineous kindred with a clinical diagnosis of CHAND syndrome. RIPK4 was previously known to be implicated in Bartsocas-Papas syndrome, the autosomal recessive form of popliteal pterygium syndrome. We report here two cases of RIPK4 homozygous mutations in a fetus with severe Bartsocas-Papas syndrome and a patient with CHAND syndrome. The patient with CHAND syndrome harbored the same mutation as the one identified in the family previously reported. We thus confirm the implication of RIPK4 gene in CHAND syndrome in addition to Bartsocas-Papas syndrome and discuss genotype/phenotype correlations. © 2017 Wiley Periodicals, Inc.

Drug treatment of metabolic syndrome.

Altabas, Velimir

2013-08-01

The metabolic syndrome is a constellation of risk factors for cardiovascular diseases including: abdominal obesity, a decreased ability to metabolize glucose (increased blood glucose levels and/or presence of insulin resistance), dyslipidemia, and hypertension. Patients who have developed this syndrome have been shown to be at an increased risk of developing cardiovascular disease and/or type 2 diabetes. Genetic factors and the environment both are important in the development of the metabolic syndrome, influencing all single components of this syndrome. The goals of therapy are to treat the underlying cause of the syndrome, to reduce morbidity, and to prevent complications, including premature death. Lifestyle modification is the preferred first-step treatment of the metabolic syndrome. There is no single effective drug treatment affecting all components of the syndrome equally known yet. However, each component of metabolic syndrome has independent goals to be achieved, so miscellaneous types of drugs are used in the treatment of this syndrome, including weight losing drugs, antidiabetics, antihypertensives, antilipemic and anticlothing drugs etc. This article provides a brief insight into contemporary drug treatment of components the metabolic syndrome.

A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

Kallmann syndrome and ichthyosis: a case of contiguous gene deletion syndrome

Full Text Available Kallmann syndrome is a genetically heterogeneous form of hypogonadotropic hypogonadism caused by gonadotropin-releasing hormone deficiency and characterized by anosmia or hyposmia due to hypoplasia of the olfactory bulbs; osteoporosis and metabolic syndrome can develop due to longstanding untreated hypogonadism. Kallmann syndrome affects 1 in 10 000 men and 1 in 50 000 women. Defects in 17 genes, including KAL1, have been implicated. Kallmann syndrome can be associated with X-linked ichthyosis, a skin disorder characterized by early onset dark, dry, irregular scales affecting the limb and trunk, caused by a defect of the steroid sulfatase gene (STS. Both KAL1 and STS are located in the Xp22.3 region; therefore, deletions in this region cause a contiguous gene syndrome. We report the case of a 32-year-old man with ichthyosis referred for evaluation of excessive height (2.07 m and weight (BMI: 29.6 kg/m2, microgenitalia and absence of secondary sex characteristics. We diagnosed Kallmann syndrome with ichthyosis due to a deletion in Xp22.3, a rare phenomenon.

2011-01-01

Full Text Available There are multiple genetic disorders with known or unknown etiology grouped under obesity syndromes. Inspite of having multisystem involvement and often having a characteristic presentation, the understanding of the genetic causes in the majority of these syndromes is still lacking. The common obesity syndromes are Bardet-Biedl, Prader-Willi, Alstrom, Albright's hereditary osteodystrophy, Carpenter, Rubinstein-Taybi, Fragile X, and Börjeson-Forssman-Lehman syndrome. The list is ever increasing as new syndromes are being added to it. One of the recent additions is MOMO syndrome, with about five such cases being reported in literature. Expanding the spectrum of clinical features, we report the first case of MOMO syndrome from India with lobar variant of holoprosencephaly and cryptorchidism, which have not been reported previously.

Full Text Available Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD and obstructive sleep apnea (OSA, was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from either condition alone. Given the high prevalence of each solitary disease, overlap syndrome is also likely to be common and clinically relevant. Despite the fact that overlap syndrome has been described in the literature for nearly 30 years, paucity of evaluations and studies limited the discussion on diagnosis, prevalence, pathophysiology, treatment, and outcomes of this disease. This review article addresses these issues by reviewing several recent studies conducted in Iran or other countries. This review suggests that overlap syndrome has worse outcomes than either disease alone. Our findings accentuated the urgent need for further studies on overlap syndrome and all overlaps between OSA and chronic pulmonary disease to provide a deeper insight into diagnosis and non-invasive treatments of this disease.

The refeeding syndrome may occur during reintroduction of carbohydrates in malnourished patients. This syndrome is characterized by reduced plasma electrolyte levels, hypophosphataemia being most prevalent. The symptoms can vary from minor symptoms to severe neurological or cardiac symptoms. The pathophysiological mechanism comprises an increase in insulin levels, resulting in shifts of phosphate, potassium and magnesium into the intracellular environment, as well as fluid retention and relative deficiency of vitamin B1. There is growing interest in the screening and treatment of patients with malnutrition, due to which the incidence of refeeding syndrome is probably increasing. Currently, there is no single definition of this syndrome and therefore there is no solid scientific basis for screening and treatment. In this article we describe the rationale for screening and additional laboratory investigations. A prospective, controlled trial is important to define the clinical relevance of the refeeding syndrome and optimize its treatment.

Metabolic syndrome and the presence of metabolic syndrome components are risk factors for cardiovascular disease (CVD). However, the association between personality traits and metabolic syndrome remains controversial, and few studies have been conducted in East Asian populations. We measured personality traits using the Japanese version of the Eysenck Personality Questionnaire (Revised Short Form) and five metabolic syndrome components-elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose-in 1322 participants aged 51.1±12.7years old from Kakegawa city, Japan. Metabolic syndrome score (MS score) was defined as the number of metabolic syndrome components present, and metabolic syndrome as having the MS score of 3 or higher. We performed multiple logistic regression analyses to examine the relationship between personality traits and metabolic syndrome components and multiple regression analyses to examine the relationship between personality traits and MS scores adjusted for age, sex, education, income, smoking status, alcohol use, and family history of CVD and diabetes mellitus. We also examine the relationship between personality traits and metabolic syndrome presence by multiple logistic regression analyses. "Extraversion" scores were higher in those with metabolic syndrome components (elevated waist circumference: P=0.001; elevated triglycerides: P=0.01; elevated blood pressure: P=0.004; elevated fasting glucose: P=0.002). "Extraversion" was associated with the MS score (coefficient=0.12, P=0.0003). No personality trait was significantly associated with the presence of metabolic syndrome. Higher "extraversion" scores were related to higher MS scores, but no personality trait was significantly associated with the presence of metabolic syndrome. Copyright © 2018 Elsevier Inc.

Full Text Available Sneddon’s syndrome is usually characterized by the association of an ischemic cerebrovascular disease and a widespread livedo reticularis. The incidence of Sneddon syndrome is 4/1000 000. We present 42-year-old woman with livedo reticularis, recurrence ischaemic cerebrovascular accidents, two repetitive miscarriages and positive anti-2GPi antibodies. Skin biopsy specimens reveal inflammatory changes of small- to medium-sized arteries and subendothelial proliferation and fibrosis. The diagnosis Sneddon syndrome is confirmed by skin biopsy, and MR evidence. We suggest that anti-2GPi antibodies may be pathophysiologically related to the clinical manifestation observed in some patients with Sneddon syndrome.

Full Text Available Sjogren′s syndrome, also known as "Mikulicz disease" or "Sicca syndrome" is a systemic autoimmune disease in which immune cells attack and destroy the exocrine glands that produce tears and saliva. It can exist by itself (primary Sjogren syndrome or develop in association with another disorder such as rheumatoid arthritis, systemic sclerosis, primary biliary cirrhosis or Hashimoto thyroiditis (associated Sjogren syndrome. Hallmarks are the dry mouth and dry eyes known as the Sicca syndrome. Sjogren syndrome affects t million to 4 million people in the United States- Most are over 40 years old at the time of diagnosis. As there is no known cure for Sjogren syndrome, treatment focuses on relieving symptoms and preventing complications. The most serious complication associated with primary Sjogren syndrome is the development of a lymphoproliferative disease. primarily non-Hodgkin lymphoma.

Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. Later, the diagnosis was confirmed by genetic analysis. This female is the oldest living patient with Williams syndrome in Hungary. Orv Hetil. 2017; 158(47): 1883-1888.

This study assessed the association of metabolic syndrome and metabolic syndrome score with the predicted forced vital capacity and predicted forced expiratory volume in 1 s (predicted forced expiratory volume in 1 s) values in Korean non-smoking adults. We analysed data obtained from 6684 adults during the 2013-2015 Korean National Health and Nutrition Examination Survey. After adjustment for related variables, metabolic syndrome ( p metabolic syndrome score ( p metabolic syndrome score with metabolic syndrome score 0 as a reference group showed no significance for metabolic syndrome score 1 [1.061 (95% confidence interval, 0.755-1.490)] and metabolic syndrome score 2 [1.247 (95% confidence interval, 0.890-1.747)], but showed significant for metabolic syndrome score 3 [1.433 (95% confidence interval, 1.010-2.033)] and metabolic syndrome score ⩾ 4 [1.760 (95% confidence interval, 1.216-2.550)]. In addition, the odds ratio of restrictive pulmonary disease of the metabolic syndrome [1.360 (95% confidence interval, 1.118-1.655)] was significantly higher than those of non-metabolic syndrome. Metabolic syndrome and metabolic syndrome score were inversely associated with the predicted forced vital capacity and forced expiratory volume in 1 s values in Korean non-smoking adults. In addition, metabolic syndrome and metabolic syndrome score were positively associated with the restrictive pulmonary disease.

Ünal, Dilek; Akdemir, Devrim

2016-01-01

Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by chronic motor and vocal tics. Although it is a common disorder in childhood, the etiology of Tourette Syndrome has not been fully elucidated yet. Studies, -conducted so far- have revealed differences in neurobiological structures of individuals who suffer from Tourette Syndrome. The objective of this review is to assess etiological and pathophysiological studies in the Tourette Syndrome literature. An electronical search was conducted in PubMed database using the keywords tic disorders, Tourette Syndrome, neurobiology, genetics, neuroimaging and animal models. Research and review studies published between 1985 and 2015, with a selection preference towards recent publications, were reviewed. According to the studies, genetic predisposition hypothesis is considered as a priority. However, a precise genetic disorder associated with Tourette Syndrome has not been found. The evidence from postmortem and neuroimaging studies in heterogenous patient groups and animal studies supports the pathological involvement of cortico-striato-thalamo-cortical (CSTC) circuits in Tourette Syndrome. Consequently, the most emphasized hypothesis in the pathophysiology is the dopaminergic dysfunction in these circuits. Furthermore, these findings of the animal, postmortem and neuroimaging studies have confirmed the neurodevelopmental hypothesis of Tourette Syndrome. In conclusion, more studies are needed to understand the etiology of the disorder. The data obtained from neurobiological studies of the disorder will not only shed light on the way of Tourette Syndrome, but also guide studies on its treatment options.

[Menopause and metabolic syndrome].

Science.gov (United States)

Meirelles, Ricardo M R

2014-03-01

The incidence of cardiovascular disease increases considerably after the menopause. One reason for the increased cardiovascular risk seems to be determined by metabolic syndrome, in which all components (visceral obesity, dyslipidemia, hypertension, and glucose metabolism disorder) are associated with higher incidence of coronary artery disease. After menopause, metabolic syndrome is more prevalent than in premenopausal women, and may plays an important role in the occurrence of myocardial infarction and other atherosclerotic and cardiovascular morbidities. Obesity, an essential component of the metabolic syndrome, is also associated with increased incidence of breast, endometrial, bowel, esophagus, and kidney cancer. The treatment of metabolic syndrome is based on the change in lifestyle and, when necessary, the use of medication directed to its components. In the presence of symptoms of the climacteric syndrome, hormonal therapy, when indicated, will also contribute to the improvement of the metabolic syndrome.

Bobot, Mickaël; Coen, Matteo; Simon, Clémentine; Daniel, Laurent; Habib, Gilbert; Serratrice, Jacques

2018-01-01

Abstract Rationale: The life-threatening drug rash with eosinophilia and systemic symptoms (DRESS) syndrome occurs most commonly after exposure to drugs, clinical features mimic those found with other serious systemic disorders. It is rarely associated with thrombotic microangiopathy. Patient concerns: We describe the unique case of a 44-year-old man who simultaneously experienced DRESS syndrome with thrombotic microangiopathy (TMA) after a 5 days treatment with fluindione. Diagnoses: Clinical evaluation leads to the discovery of an underlying lymphangiomatosis, due to a Noonan syndrome. Intervetions: The anticoagulant was withdrawn, and corticosteroids (1 mg/kg/day) and acenocoumarol were started. Outcomes: Clinical improvement ensued. At follow-up the patient is well. Lessons: The association of DRESS with TMA is a rare condition; we believe that the presence of the underlying Noonan syndrome could have been the trigger. Moreover, we speculate about the potential interrelations between these entities. PMID:29642153

2017-12-01

Full Text Available Metabolic syndrome has been defined as a global issue since it affects a lot of people. Numerous factors are involved in metabolic syndrome development. It has been described that metabolic syndrome has negative consequences on health. Consequently, a lot of treatments have been proposed to palliate it such as drugs, surgery or life style changes where nutritional habits have shown to be an important point in its management. The current study reviews the literature existing about the actual epidemiology of metabolic syndrome, the components involucrate in its appearance and progression, the clinical consequences of metabolic syndrome and the nutritional strategies reported in its remission. A bibliographic search in PubMed and Medline was performed to identify eligible studies. Authors obtained that metabolic syndrome is present in population from developed and undeveloped areas in a huge scale. Environmental and genetic elements are involucrate in metabolic syndrome development. Metabolic syndrome exponentially increased risk of cardiovascular disease, some types of cancers, diabetes mellitus type 2, sleep disturbances, etc. Nutritional treatments play a crucial role in metabolic syndrome prevention, treatment and recovery.

The aim of this study is to compare metabolic syndrome with syndrome Z growing epidemic in terms of risk factors, demographic variables, and gender differences in our large cohort at southeastern area in Turkey. Data of patients admitted to sleep clinic in University of Gaziantep from January 2006 to January 2011 were retrospectively evaluated. ATP III and JNC 7 were used for defining metabolic syndrome and hypertension. Data of 761 patients were evaluated. Hypertension, diabetes mellitus, coronary artery disease, pulmonary hypertension, and left ventricular hypertrophy were more common in patients with syndrome Z than in patients without metabolic syndrome. Age, waist/neck circumferences, BMI, triglyceride, glucose, and Epworth sleepiness scale score were detected higher, whereas the minimum oxygen saturation during sleep was lower in patients with syndrome Z. Metabolic syndrome was more common in sleep apneic subjects than in controls (58 versus 30 %). Female sleep apneics showed higher rate of metabolic syndrome than those of males (74 versus 52 %). Hypertension, diabetes mellitus, coronary artery disease, and left ventricular hypertrophy were detected higher in males with syndrome Z than in males without metabolic syndrome. Snoring and excessive daytime sleepiness were detected higher in females with syndrome Z than in females without metabolic syndrome. Systemic/pulmonary hypertension, diabetes mellitus, and left ventricular hypertrophy were more common in females with syndrome Z than in females without metabolic syndrome. Complaints of headache and systemic/pulmonary hypertension were more common among females than males with syndrome Z. Female syndrome Z patients had lower minimum oxygen saturation than male patients with syndrome Z. Metabolic syndrome in sleep apneic patients is more prevalent than in controls. All metabolic syndrome parameters were significantly different among obstructive sleep apneic patients with respect to gender with more severe

Ševela, Stanislav; Novák, František; Kazda, Antonín; Brodská, Helena

Despite being known more than 60 years, refeeding syndrome (RS) still bears many uncertainties. For example, its definition is not clear and definite, and the attitude to it varies from the complete neglect to over-prevention.The term "refeeding syndrome" refers to electrolyte and metabolic changes occurring in malnourished patients after the readministration of nutrition. These changes concern especially to phosphates and ions. Potassium, magnesium, naturism and fluids balance are involved. The changes lead to cell energetic metabolism and electric potential disturbances, with related clinical symptoms.Fully developed refeeding syndrome is quite rare; nevertheless it can be fatal for the patient. However, even its development can lead to many complications increasing the patient's morbidity and the length of stay in the hospital. Yet the refeeding syndrome is more or less predictable and if kept in mind also preventable.The aim of this article is to get the reader to know more about this metabolic phenomenon and possible attitudes towards it.

In spite of a few shortcomings such as over diagnosis and over treatment, syndromic management is a recommended practice in India for sexually transmitted infections (STIs). This study tries to find out the efficacy of syndromic management measured as symptomatic improvement in females with vaginal discharge syndrome. The objective of the study is to find out the effectiveness of syndromic management in terms of symptomatic improvement among females with vaginal discharge syndrome. A longitudinal study was conducted in Gynecology Department of Tertiary Care Hospital including 180 symptomatic females having vaginal discharge syndrome. Demographic profile, presenting complaints, menstrual history, obstetric history, partner history, and contraceptive history were noted. This was followed by clinical examination and specimen collection for laboratory tests and blood tests to find out type of STI including viral STI such as human immunodeficiency virus (HIV), herpes simplex virus (HSV), and hepatitis B surface antigen (HBsAg). Treatment was given according to syndromic management on the same day. All the participants were asked to come for follow-up after 15 days and their improvement in symptoms was noted as complete improvement, some improvement or no improvement on a five point scale. 63.9% cases showed complete improvement, while 36.1% showed some improvement. None of the patients was without any improvement. Vaginal discharge syndrome was most common between 20 and 30 years (43.4%), and 67.8% of symptomatic females with vaginal discharge syndrome belonged to the lower socioeconomic group. HSV infection was the most common (15%) associated viral infection with vaginal discharge syndrome, while hepatitis B infection was the least common (0.5%). HIV was reactive in 2.8% cases only. Syndromic management was found to be effective in relieving symptoms in most of the cases of vaginal discharge syndrome.

2013-08-01

Full Text Available The aim of this study is to report a clinical case of asymptomatic female Caucasian children with torpedo maculopathy. A 5-year-old girl was referred to our clinic for routine evaluation. The ophthalmic examination revealed best-corrected visual acuity of 20/20 in both eyes, without any changes in the biomicroscopy. Fundus examination showed normal findings in one eye, whereas in the contralateral eye it disclosed, in the temporal sector of the macular region, a whitish, atrophic, oval chorioretinal lesion with clearly defined margins. Posterior evaluations documented the stability of the lesion. Torpedo maculopathy diagnosis is based on its characteristic shape and peculiar location. The differential diagnosis has to be estabilished versus choroidal lesions (melanoma and nevus, congenital or iatrogenic hyperplasia of the retinal pigment epithelium (RPE and particularly versus the congenital pigmented lesions associated with Gardner's syndrome.

Prune belly syndrome in an Egyptian infant with Down syndrome: A case report

Full Text Available Abstract Introduction Prune belly syndrome is a rare congenital anomaly of uncertain aetiology almost exclusive to males. The association between prune belly syndrome and Down syndrome is very rare. Case presentation A 4-month-old Egyptian boy was admitted to our institute for management of acute bronchiolitis. He was born at full term by normal vaginal delivery. His mother, a 42-year-Egyptian villager with six other children, had no antenatal or prenatal care. On examination, the boy was found to be hypotonic. In addition to features of Down syndrome, karyotyping confirmed the diagnosis of trisomy 21. Ultrasound examination of the abdomen showed bilateral gross hydronephrosis with megaureter. Micturating cystourethrography showed grade V vesicoureteric reflux bilaterally with no urethral obstruction. Serum creatinine concentration was 90 μmol/litre, serum sodium was 132 mmol/litre and serum potassium was 5.9 mmol/litre. Conclusion We report an Egyptian infant with Down syndrome and prune belly syndrome. The incidence of this association is unknown. Routine antenatal ultrasonography will help in discovering renal anomalies which can be followed postnatally. Postnatal detection of prune belly syndrome necessitates full radiological investigation to detect any renal anomalies. Early diagnosis of this syndrome and determining its optimal treatment are very important in helping to avoid its fatal course.

A stillborn baby boy had findings of severe constitutional dwarfism with short limbs, short ribs, and polydactyly that were consistent with Naumoff (type III) short-rib polydactyly syndrome. He also had additional congenital anomalies, including cleft palate, notching of the upper lip, small tongue with accessory sublingual tissue. These oral and pharyngeal anomalies were consistent with Mohr (type II) oral-facial-digital syndrome. We suggest the stillborn infant represented a compound of Naumoff short-rib polydactyly syndrome (SRPS-III) and Mohr oral-facial-digital syndrome (OFDS-II). (orig.)

The Capgras syndrome in paranoid schizophrenia.

Silva, J A; Leong, G B

1992-01-01

Capgras syndrome is characterized by a delusion of impostors who are thought to be physically similar but psychologically distinct from the misidentified person. This syndrome is generally thought to be relatively rare. Most of our knowledge about Capgras syndrome derives from single case studies and small series of cases usually from diagnostically heterogeneous groups. In this article, a series of 31 patients suffering from both paranoid schizophrenia and Capgras syndrome is described. Issues pertaining to the phenomenology of Capgras syndrome, the possible relation between Capgras syndrome and other delusional misidentification syndromes, and a neurobiological hypothesis aimed at explaining Capgras syndrome are discussed.
