Autosomal recessive multiple pterygium syndrome: a new variant?

Multiple pterygium syndromes include at least 15 different entities characterized by multiple pterygia or webs of the skin and multiple congenital anomalies. We describe a female infant who presented with a distinct constellation of multiple anomalies consisting of pterygia of the inguinal, intercrural and popliteal areas, flexion contractures and arthrogryposis of some joints, craniofacial anomalies including ectropion, medial canthal web, blepharophimosis, hypoplasia of nose, oral and nasopharyngeal cavities, vocal cords and tongue, micrognathia, orolabial synechiae secondary to pterygia, low set ears, alopecia, sad and expressionless face, short neck, asymmetric nipples, anal stenosis, rectal polyp, hypoplastic labia majora, complete syndactyly of all fingers and toes, pes equinovarus, bandlike web between feet, and absence of the nails and phalangeal-palmar creases. Radiological examination showed synostosis, absence or hypoplasia of metacarpal, metatarsal and phalangeal bones on feet and hands, and hypoplasia of pelvic bones and scapulae. This pattern of anomalies does not fit entirely any of the known multiple pterygium syndromes. Autosomal recessive inheritance is most likely due to the presence of three similarly affected siblings and normal parents.

Bilaminar dual-purpose stent for placement of dental implants.

Proper placement of implants in the posterior maxillary region with poor bone density is essential to obtain long-term success. In this article, the fabrication of a bilaminar dual-purpose stent that facilitates ease in implant placement with improved verification of implant positioning is described. The outer lamina is designed for use in the computed tomography evaluation, using radiopaque markers. The verification of implant alignment and positioning, according to the determined prosthesis, is also performed with this template after modifying it for surgery. The inner lamina is designed to accept 2 removable surgical acrylic resin stents with different guide channels that avoids the risk of surgical malpractice.

Plasma soluble interleukin-2 receptor levels in patients with idiopathic thrombocytopenic purpura.

Soluble interleukin-2 receptor (slL-2R) was measured in the plasma of 31 patients with idiopathic thrombocytopenic purpura (ITP) and 22 normal controls. When thrombocytopenia persisted longer than 6 months, the diagnosis of chronic ITP was made. Twenty patients had acute ITP, 11 patients had chronic ITP, and all patients received high-dose methylprednisolone (HDMP) (30 mg/kg/d for 3 days, 20 mg/kg/d for 4 days). The sIL-2R levels of the patients were determined before being giving HDMP and 14 days after the end of HDMP therapy. Platelet counts were determined before administration of HDMP, one day after the end of HDMP therapy, and once every 28 days for 7 months thereafter. There was not a significant difference between the mean pre-treatment plasma sIL-2R levels of both acute and chronic ITP groups (P > 0.05), and these were higher than that of the control group (P < 0.001). The mean post-treatment sIL-2R level of the chronic ITP group was significantly higher than those of both the control and post-treatment acute ITP groups (P < 0.001). There were negative correlations between the plasma sIL-2R levels and platelet counts of both group patients in the pre-treatment period and between post-treatment sIL-2R levels and platelet counts in chronic ITP group (P < 0.05). We think that there was a good correlation between prognosis of ITP and sIL-2R levels after HDMP therapy, and platelet counts in patients with ITP are linked to sIL-2R levels.

Multiple vertebral segmentation defects. Brief report of three patients and nosological considerations.

Multiple vertebral segmentation defects i.e. multiple malformations of vertebrae and ribs are characterized by short neck, scoliosis, short trunk and deformity of the ribcage. There are three major subtypes; Jarcho-Levin syndrome, spondylothoracic dysostosis and spondylocostal dysostosis, with different inheritance patterns, survival rates and associated malformations. We describe three cases of multiple vertebral segmentation defects, two with familial spondylothoracic dysostosis and one with sporadic spondylothoracic dysostosis, and anomalies i.e. super-numerary breast, clubfeet deformity, myelomeningocele, intradural lipoma, and Arnold-Chiari malformation.

Relationships between serum free fatty acids and zinc, and attention deficit hyperactivity disorder: a research note.

The purpose of this study is to evaluate the relationships between serum free fatty acids (FFA) and zinc, and attention deficit hyperactivity disorder (ADHD). Forty eight children with ADHD (33 boys, 15 girls) were included in the patient group and 45 healthy volunteer children (30 boys, 15 girls) constituted the control group. The mean serum FFA level in the patient group was 0.176 +/- 0.102 mEq/L and in control group, 0.562 +/- 0.225 mEq/L (p < .001). The mean serum zinc level of patient group was 60.6 +/- 9.9 micrograms/dl and that of the control group, 105.8 +/- 13.2 micrograms/dl (p < .001). A statistically significant correlation was found between zinc and FFA levels in the ADHD group. These findings indicate that zinc deficiency may play a role in aetiopathogenesis of ADHD. Although we observed decreased FFA levels in ADHD cases, it is necessary to determine whether this condition is a principal cause of ADHD or is secondary to zinc deficiency.

The role of high dose methylprednisolone and splenectomy in the accelerated phase of Chédiak-Higashi syndrome.

The Chédiak-Higashi syndrome (CHS) is a rare autosomal recessive immunodeficiency disorder. Some cases with CHS develop the accelerated phase characterized by pancytopenia, high fever and lymphohistiocytic infiltration of liver, spleen and lymph nodes. The treatment of the accelerated phase of CHS is difficult. We describe a case with CHS in the accelerated phase who had multiple polyposis and pulmonary infiltration that was probably due to involvement of CHS. She was successfully treated with high-dose methylprednisolone at her first admission. At her second admission, splenectomy was performed to remove hypersplenism, and her clinical, radiological and hematological findings improved significantly.

Campomelic dysplasia associated with mandibular clefting.

Campomelic dysplasia (CD), is a lethal dwarfism of the newborn, characterised by rhizomelic dwarfism, bowed femora and tibiae, associated with other skeletal and extraskeletal defects. It is suggested that there are long-limbed and short-limbed varieties. Various clinical and radiological anomalies have been described in both types of CD. Here, we describe for the first time a cleft in the mandibula in a patient with campomelic dysplasia.

Serum interleukin-1 and granulocyte-macrophage colony-stimulating factor levels in protein malnourished patients during acute infection.

OBJECTIVE: To investigate the response of serum interleukin-1 (IL-1) and granulocyte-macrophage colony-stimulating factor (GM-CSF) to infection of malnourished patients. DESIGN: Prospective observational study. SETTING: Paediatric clinics of Karadeniz Technical University, Faculty of Medicine, Trabzon, Turkey. SUBJECTS: 13 protein-depleted (kwashiorkor marasmic kwashiorkor), 15 marasmic nutritionally repleted kwashiorkor (NRK), and 12 well-nourished control subjects. INTERVENTIONS: Clinical and laboratory data, and serum IL-1 and GM-CSF levels during acute infections were examined. MAIN OUTCOME MEASURES: White blood cell count, pc of circulating neutrophils (%PNL), serum total protein, albumin (ALB), IL-1 and GM-CSF levels. RESULTS: Fever, pcPNL, serum IL-1 and GM-CSF levels of kwashiorkor patients were lower than those of marasmic and control patients (p < 0.005). Fever, neutrophil pc(PNLpc), serum IL-1 and GM-CSF levels of NRK patients during further acute infection were not significantly different from those of marasmic and control patients, but higher than those of the kwashiorkor patients. Although there were positive correlations between serum IL-1 and ALB levels (r = 0.922, p < 0.001), and between serum GM-CSF and ALB levels (r0.730, p = 0.005) in the kwashiorkor group, there were not significant correlations between the same parameters in the other groups (r < 0.5, p > 0.05). And also, although there was not significant correlations between PNL% and IL-1 levels in the kwashiorkor group (r0.312, p = 0.299), there were significant positive correlations between the same parameters in the other groups (r < 0.5, p > 0.05). However, significant positive correlations were found between fever and IL-1 levels, and between IL-1 and GM-CSF levels in all groups (r > 0.5, p < 0.05). CONCLUSION: The responses of serum IL-1 and GM-CSF to acute infection of kwashiorkor patients are defective, and nutritional-repletion therapies restore the production of these cytokines.

Marginal reservoirs for multiunit castings.

This study measured the distortion of one-piece base metal four-unit fixed partial dentures and recorded the effect of positioning "marginal reservoirs" on the wax patterns. Standard wax patterns were made in a special three-piece stainless steel mold. Twenty anterior prostheses were cast: 10 for the experimental group and 10 for the control group. The prostheses were cast in a nickel-chromium alloy and were measured with a traveling microscope with a micrometer scale. Premarked points were designated on gingivoaxial line angles for buccolingual and mesiodistal distances and diameters to record marginal discrepancies of specimens with or without marginal reservoirs. Castings with marginal reservoirs distorted significantly less than did the control fixed partial dentures.

Aicardi syndrome: a variant example with new clinical findings.

Aicardi syndrome, which shows X-linked dominant inheritance, is characterized by corpus callosum agenesis, infantile spasms, chorioretinitis, chorioretinal lacunae, psychomotor retardation, microphthalmy, cerebral atrophy and vertebral abnormalities. A 3/12 year-old girl with Aicardi syndrome who has dilated right lateral ventricle and leucomalacy in the right frontal lobe on magnetic resonance imaging (MRI) is presented. As far as we know, this combination of symptoms was not described previously in the literature.
