A systematic review: facial, dental and orthodontic findings and orofacial diagnostics in patients with FASD

BackgroundThe fetal alcohol spectrum disorder is a group of developmental disorders caused by maternal alcohol consumption. Patients with fetal alcohol syndrome show abnormal orofacial features. This review presents an overview over the facial, oral, dental or orthodontic findings and diagnostic tools concerning these features.MethodsFor this systematic review Cochrane, Medline and Embase databases were considered and the review was performed according to the PRISMA checklist. Two independent reviewers evaluated all studies and recorded results in a summary of findings table. Risk of bias was analyzed via Quadas-2 checklist.Results61 studies were eligible for inclusion. All included studies were clinical studies. Methods and results of the studies were not comparable, guidelines or methods for the detection of FASD varied across studies. Facial features most often measured or found as distinguishing parameter were: palpebral fissure length, interpupillary or innercanthal distance, philtrum, upper lip, midfacial hypoplasia or head circumference.ConclusionsThis review shows that to date a multitude of heterogeneous guidelines exists for the diagnosis of FASD. Uniform, objective diagnostic criteria and parameters for the orofacial region in FASD diagnosis are needed. A bio database with values and parameters for different ethnicities and age groups should be made available for diagnosis

A rare case of metastatic renal carcinoid

<p>Abstract</p> <p>Background</p> <p>Carcinoid is an endocrine cell tumor with low-grade atypia, which is generally a low-grade malignant cancer with a good prognosis. Metastatic renal carcinoid is even rarer than primary carcinoids.</p> <p>Case presentation</p> <p>We present our experience of a patient with metastatic renal carcinoid from the gastrointestinal tract.</p> <p>Conclusions</p> <p>The carcinoid tumor of the kidney in our patient, who had a history of liver metastasis from rectal carcinoid, was considered metastatic based on the pathological findings.</p

Effects of estrogen deficiency during puberty on maxillary and mandibular growth and associated gene expression – an μCT study on rats

Background Estrogen is a well-known and important hormone involved in skeletal homeostasis, which regulates genes involved in bone biology. Some studies support that estrogen is important for craniofacial growth and development. Therefore this in vivo animal study aimed to investigate, whether and in which way low estrogen levels in the prepubertal period affect craniofacial development in the postpubertal stage and to quantify the gene expression of RANK, RANKL and OPG in cranial growth sites in ovariectomized estrogen-deficient rats during puberty. Methods Control (sham-operated, n = 18) and ovariectomy (OVX, n = 18) surgeries were performed on 21-days-old female Wistar rats. Animals euthanized at an age of 45 days (pubertal stage) were used for gene expression analyses (n = 6 per group) and immunohistochemistry of RANK, RANKL and OPG. Animals euthanized at 63 days of age (post-pubertal stage) were used for craniofacial two-dimensional and three-dimensional craniofacial measurements using μCT imaging (n = 12 per group). Results In the μCT analysis of the mandible and maxilla many statistically significant differences between sham-operated and OVX groups were observed, such as increased maxillary and mandibular bone length in OVX animals (p < 0.05). Condylar volume was also significantly different between groups (p < 0.05). The sham-operated group showed a higher level of RANK expression in the midpalatal suture (p = 0.036) and the RANKL:OPG ratio levels were higher in the OVX group (p = 0.015). Conclusions Our results suggest that estrogen deficiency during the prepubertal period is associated with alterations in the maxillary and mandibular bone length and condylar growth

Acute inflammatory myelopathies

Inflammatory injury to the spinal cord causes a well-recognized clinical syndrome. Patients typically develop bilateral weakness, usually involving the legs, although the arms may also become affected, in association with a pattern of sensory changes that suggests a spinal cord dermatomal level. Bowel and bladder impairment is also common in many patients. Recognition of the clinical pattern of spinal cord injury should lead clinicians to perform imaging studies to evaluate for compressive etiologies. MRI of the spine is particularly useful in helping visualize intraparenchymal lesions and when these lesions enhance following contrast administration a diagnosis of myelitis is made. Cerebrospinal fluid analysis can also confirm a diagnosis of myelitis when a leukocytosis is present. There are many causes of non-compressive spinal cord injury including infectious, parainfectious, toxic, nutritional, vascular, systemic as well as idiopathic inflammatory etiologies. This review focuses on inflammatory spinal cord injury and its relationships with multiple sclerosis, neuromyelitis optica, acute disseminated encephalomyelitis and systemic collagen vascular and paraneoplastic diseases
