- A novel de novo deletion of chromosome 7 [46,XX,del(7)(p14.2 p15.1)] in a child with feeding problemsPublication . Antunes, H; Gonçalves, JP; Silva, E; Teles, NThe phenotype and severity of symptoms associated with deletions on chromosome 7 are directly proportional to the size of the deleted segment. Distal and interstitial deletions have been described in 40 cases. In this report the authors aim to report a child with a novel de novo interstitial deletion on chromosome 7, with the following karyotype: 46,XX,del(7)(p14.2 p15.1). We described a female, born at 38 weeks with intrauterine growth restriction and feeding problems with episodes of cyanosis after feedings and failure to thrive. Physical examination showed low implantation of ears, hypertelorism, oblique palpebral fissures, retrognathia, and palate ogived, with insertion anomalies of the toes, poor facial expression and mild axial hypotonia. Transfontanelar ultrasound, magnetic resonance imaging, bronchofibroscopy and metabolic studies were normal. She was hospitalized until the 32nd day of life. She started speech therapy and presented improvements in swallowing. The percutaneous endoscopic gastrostomy was removed at 36 months. She had recurrent urinary tract infection with normal dimercaptosuccinic acid but with a vesicoureteral reflux (grade III). Imagiological studies revealed a bilateral osteonecrosis of femoral epiphysis (Legg-Calvé-Perthes disease). Currently (6years-old), she is being normally fed (body mass index=15.8kg/m(2)). Her weight is 16.4kg (3rd centile) and length is 105cm (3rd to 5th centiles). She has a mild delay of psychomotor development impairment and some speech problems. This is the first case report of a patient with this de novo small interstitial deletion on chromosome 7. This rare chromosomal abnormality was associated with severe feeding problems in the first years of life.
- Omental whirl associated with bilateral inguinal hernia: a case reportPublication . Silva, E; Carvalho, AF; Rocha, D; Rodrigues, AM; Pereira, R; Rodrigues, AJ; Leão, PTorsion of the omentum is a rare cause of abdominal pain. It is clinically similar to common causes of acute surgical abdomen and is often diagnosed during surgery. Inguinal hernia is a common condition but not frequently related with torsion of the omentum. CASE PRESENTATION: A 40-year-old Caucasian man came to our emergency department with abdominal pain of the left quadrant and abdominal distension for 2 days. His medical history included an untreated left inguinal hernia in the last year. Computed tomography revealed densification of mesocolon with left omentum "whirl" component and other signs of omental torsion. During an exploratory laparoscopy, a wide twist of his omentum with necrotic alterations that extended to the bilateral inguinal hernial content was observed. Omentectomy and surgical repair of bilateral inguinal hernia were performed. CONCLUSIONS: Torsion of the omentum is a rare entity and usually presents a diagnostic challenge. The use of abdominal computed tomography can help diagnosing torsion of the omentum preoperatively and, thus, prevents a surgical approach. Nonetheless, some cases of torsion of the omentum require surgical repair. Accordingly, a laparoscopic approach is minimally invasive and efficient in performing omentectomy.
- Should tumbling E go out of date in amblyopia screening? Evidence from a population-based sample normative in children aged 3-4 yearsPublication . Guimarães, S; Fernandes, T; Costa, P; Silva, EAIMS: To determine a normative of tumbling E optotype and its feasibility for visual acuity (VA) assessment in children aged 3-4 years. METHODS: A cross-sectional study of 1756 children who were invited to participate in a comprehensive non-invasive eye exam. Uncorrected monocular VA with crowded tumbling E with a comprehensive ophthalmological examination were assessed. Testability rates of the whole population and VA of the healthy children for different age subgroups, gender, school type and the order of testing in which the ophthalmological examination was performed were evaluated. RESULTS: The overall testability rate was 95% (92% and 98% for children aged 3 and 4 years, respectively). The mean VA of the first-day assessment (first-VA) and best-VA over 2 days' assessments was 0.14 logMAR (95% CI 0.14 to 0.15) (decimal=0.72, 95% CI 0.71 to 0.73) and 0.13 logMAR (95% CI 0.13 to 0.14) (decimal=0.74, 95% CI 0.73 to 0.74). Analysis with age showed differences between groups in first-VA (F(3,1146)=10.0; p<0.001; η2=0.026) and best-VA (F(3,1155)=8.8; p<0.001; η2=0.022). Our normative was very highly correlated with previous reported HOTV-Amblyopia-Treatment-Study (HOTV-ATS) (first-VA, r=0.97; best-VA, r=0.99), with 0.8 to 0.7 lines consistent overestimation for HOTV-ATS as described in literature. Overall false-positive referral was 1.3%, being specially low regarding anisometropias of ≥2 logMAR lines (0.17%). Interocular difference ≥1 line VA logMAR was not associated with age (p=0.195). CONCLUSIONS: This is the first normative for European Caucasian children with single crowded tumbling E in healthy eyes and the largest study comparing 3 and 4 years old testability. Testability rates are higher than found in literature with other optotypes, especially in children aged 3 years, where we found 5%-11% better testability rates.
