Spontaneous resolution in congenital nasolacrimal obstruction after 12 months

A retrospective observational study was performed in order to evaluate the possibility of spontaneous resolution of tearing in the congenital nasolacrimal obstruction (CNLO). Twenty-seven CNLO child carriers with spontaneous tearing resolution were evaluated according to sex, age of starting and end of symptoms. The data were evaluated by the Chi-Square Test and non-parametric Mann-Whitney test (p ≤ 0.05). Spontaneous resolution occurred between ages 3 and 48 months (Median = 14 months; Mean = 16.2 ± 10.5 months). The period in which the child presented tearing varied from 2 months to 47.5 months (Median = 12 months) and was similar for both sexes, with or without realization of massage. Our data support the possibility of CNLO spontaneous resolution in children beyond 12 months of age, allowing us to suggest postponed probing beyond this time period. Copyright © Informa Healthcare.

Management of congenital nasolacrimal duct obstruction - Latin American study

PURPOSE

Congenital nasolacrimal duct obstruction:Comparison of two different treatment algorithms

Purpose: To clarify the most appropriate treatment regimen for congenital nasolacrimal duct obstruction (CNLDO). Methods: A retrospective observational analysis was performed of patients undergoing probing with or without intubation to treat CNLDO in a single institution (Royal Victoria Hospital, Belfast) from 2006 to 2011. Results: Based on exclusion criteria, 246 eyes of 177 patients (aged 0 to 9.8 years with a mean age of 2.1 years) were included in this study: 187 (76%) eyes had successful outcome at first intervention with primary probing, whereas 56 (23%) eyes underwent secondary intervention. There were no significant differences by gender, age, or obstruction complexity between the successful and unsuccessful patients with first intervention. For those patients requiring secondary intervention, 16 of 24 (67%) eyes had successful probing, whereas 22 of 24 (92%) had successful intubation. Patients with intubation as a secondary procedure were significantly more likely to have a successful outcome (P = .037). Statistical analysis was performed using the Fisher's exact test and Barnard's exact test. Conclusions: Primary probing for CNLDO has a high success rate that is not adversely affected by increasing age. This study also indicates that if initial probing is unsuccessful, nasolacrimal intubation rather than repeat probing yields a significantly higher success rate.

Obstrução nasolacrimal congênita: fatores relacionados com a possibilidade de cura

OBJETIVO: Avaliar a chance de cura da obstrução nasolacrimal congênita de acordo com a idade em que se deu o início da epífora e o tratamento efetuado. MÉTODOS: Quarenta crianças portadoras de obstrução nasolacrimal congênita, atendidas no período de 1997 a 1999, foram estudadas retrospectivamente, avaliando-se: idade do início da epífora, tratamento efetuado e possibilidade de cura. Os dados foram submetidos à análise estatística e usou-se o teste de proporções binomiais para contrastes entre e dentro de populações. RESULTADOS: A proporção de cura foi menor quando a epífora se iniciou em idade superior a 4 meses de vida, havendo possibilidade de cura com massagem e/ou sondagem em mesmas proporções, sendo possível obter cura também em crianças com idade superior a 3 anos de vida. CONCLUSÃO: Os resultados mostram que a possibilidade de cura sofre a influência da época do início da epífora e que o tratamento com massagem ou sondagem pode ser efetivo, mesmo em crianças com idade superior a 3 anos de idade.

Obstrução nasolacrimal congênita: fatores relacionados com a melhora após sondagem terapêutica

OBJETIVO: Avaliar em crianças portadoras de obstrução nasolacrimal congênita (ONLC) os índices de cura com a sondagem das vias lacrimais e os fatores relacionados com o insucesso do procedimento. MÉTODO: Estudo retrospectivo observacional, incluindo 80 crianças portadoras de obstrução nasolacrimal congênita, submetidas à sondagem terapêutica da via lacrimal. As crianças foram avaliadas quanto ao sexo, faixa etária e resultado da sondagem. Os dados obtidos foram avaliados por estatística descritiva, teste de Goodman e pelo teste não paramétrico de Mann-Whitney, com nível de significância de 5%. RESULTADOS: A cura ocorreu igualmente em ambos os sexos. A média de idade das crianças que se beneficiaram da sondagem foi de 19,95±11,4 meses e a das crianças que não se curaram foi de 23,37±15,2 meses. A possibilidade de cura ocorreu igualmente nas faixas etárias acima dos 6 meses. Observou-se nas crianças que não se curaram com a sondagem a existência de alterações nasais como rinite, hipertrofia de adenóide ou de cornetos, desvio de septo e sinusopatia. CONCLUSÃO: A possibilidade de cura com a sondagem não varia significativamente mesmo nas idades acima dos 12 meses. Entre as causas de insucesso com o procedimento devem ser incluídas as alterações da cavidade nasal.

Obstrução nasolacrimal congênita - Diagnóstico e tratamento

Patients with congenital nasolacrimal obstruction (CNLO) were evaluated at the Lacrimal Apparatus Service of Botucatu Faculty of Medicine - UNESP from 1990 to 1993. 45 children were seen at this period with CNLO. The diagnosis was confirmed by dacryocystography (DCG). Obstruction was unilateral in 77,7% of the patients; 68,1% at Arlt Sinus and 43,6% had lacrimal sac grade 1. Probing was made in children older than 6 months, under general anaesthesia, after DCG was performed. Cure was greater in children age 6 to 12 months with obstruction at Hasner's Valve and without dilation of lacrimal sac.

Cinedacryocystography in the diagnosis of lacrimal obstruction in children

Purpose: To analyze the cinedacryocystography in children with congenital nasolacrimal obstruction suspicion. Methods: The cinedacryocystographic examination was done in 143 children (58% of girls and 42% of boys) younger than 5 years old, suspected of congenital nasolacrimal obstruction. The exams were done under general anesthesia and the children were probed immediately when obstruction was detected. Results: Epiphora, discharge or both were the most common complaints. Nevertheless 11% children had undergone unsuccessfully probing once, no one had any radiologic evaluation previously. The cinedacryocystographic exam showed nasolacrimal duct obstruction in 65,73%. Permeable lacrimal vies were presented in 34,3% of the children with epiphora. The obstruction was mainly at the Arlt's sinus. Using the cinedacryocystography, it was possible to observe the lacrimal sac enlargement and alterations in the contiguous structures such as hypertrophic turbinates (91,1%), sinusitis (44,6%) and septum deviation (24,1%). Conclusion: Cinedacryocystographic evaluation provides important information about lacrimal system obstruction in children, therefore, it is useful in all children with suspected congenital lacrimal obstruction.

Congenital nasolacrimal duct fistula in Brown Swiss cattle

BACKGROUND An increased incidence of nasolacrimal duct fistula in the offspring of dam J and three of her sons (bulls A, B and C) prompted a study to investigate the prevalence and clinical manifestation of this anomaly. The dam J, bull B, 255 direct offspring of bulls A, B, and C and eight other direct and indirect offspring of cow J were examined. The periocular region of each animal was examined for unilateral or bilateral nasolacrimal duct fistula and the location, appearance and size of the lesions. RESULTS Of 265 cattle examined, 54 had unilateral (n = 24) or bilateral fistula (n = 30). The prevalence of affected offspring differed significantly among the three bulls. The fistulae were located medial to the medial canthus of the eye and were 1 to 10 mm (median, 1 mm) in height and 1 to 12 mm (median, 2 mm) in length. The shape of the opening was circular in 58, oval in 23 and slit-like in three. One other animal had a large opening with an atypical shape and another had an abnormal medial canthus with several fistulous openings. Seventy openings were pigmented and 52 were hairless. The fistulae were clinically significant in 12 animals. CONCLUSIONS The findings suggest a hereditary cause of nasolacrimal duct fistula in Brown Swiss cattle.

Computed tomographic dacryocystography in children undergoing balloon dacryoplasty

PURPOSE To ascertain whether the volume and circumference of the lacrimal sac and nasolacrimal duct as measured by contrast-enhanced computed tomographic dacryocystography (CT-DCG) before and after balloon dacryoplasty could be used to predict clinical success in children with congenital nasolacrimal obstruction. METHODS Nasolacrimal ducts of children aged 2 to 6 years with clinical signs of congenital nasolacrimal duct obstruction undergoing balloon dilation were imaged with contrast-enhanced CT-DCG before and 5 minutes after the procedure. The circumference of the most dilated portion of the lacrimal sac was measured on the axial plane. The volume of contrast within the nasolacrimal duct and sac was also measured before and after the procedure. Clinical success was defined as the disappearance of signs of epiphora. RESULTS A total of 18 nasolacrimal ducts of 13 children were included. The average circumference of the most dilated portion of the lacrimal sac was 1.30 +/- 0.45 cm (range, 0.64-2.50 cm) before the procedure. The average contrast volume was 0.12 +/- 0.08 cm(3) (range, 0.01-0.38 cm(3)) before and 0.07 +/- 0.06 cm(3) (range, 0.01-0.20 cm(3)) after (P = 0.01). Data were analyzed using multivariate logistic regression with a backward variable input model; a decrease in contrast volume before and after dilation (P = 0.04) was associated with clinical success, whereas the larger size of the most dilated portion of the lacrimal sac (P = 0.01) was associated with clinical failure. CONCLUSIONS Contrast-enhanced CT-DCG provides useful information about nasolacrimal anatomy in children with congenital nasolacrimal duct obstruction. The decrease in contrast volume before and after balloon dilation was predictive of success; A larger size of the most dilated portion of the lacrimal sac was associated with clinical failure.

Prenatal ultrasonographic detection of gastrointestinal obstruction: results from 18 European congenital anomaly registries.

OBJECTIVES: We evaluated the prenatal detection of gastrointestinal obstruction (GIO, including atresia, stenosis, absence or fistula) by routine ultrasonographic examination in an unselected population all over Europe. METHODS: Data from 18 congenital malformation registries in 11 European countries were analysed. These multisource registries used the same methodology. All fetuses/neonates with GIO confirmed within 1 week after birth who had prenatal sonography and were born during the study period (1 July 1996 to 31 December 1998) were included. RESULTS: There were 670 793 births in the area covered and 349 fetuses/neonates had GIO. The prenatal detection rate of GIO was 34%; of these 40% were detected < or = 24 weeks of gestation (WG). A total of 31% (60/192) of the isolated GIO were detected prenatally, as were 38% (59/157) of the associated GIO (p=0.26). The detection rate was 25% for esophageal obstruction (31/122), 52% for duodenal obstruction (33/64), 40% for small intestine obstruction (27/68) and 29% for large intestine obstruction (28/95) (p=0.002). The detection rate was higher in countries with a policy of routine obstetric ultrasound. Fifteen percent of pregnancies were terminated (51/349). Eleven of these had chromosomal anomalies, 31 multiple malformations, eight non-chromosomal recognized syndromes, and one isolated GIO. The participating registries reflect the various national policies for termination of pregnancy (TOP), but TOPs after 24 WG (11/51) do not appear to be performed more frequently in countries with a liberal TOP policy. CONCLUSION: This European study shows that the detection rate of GIO depends on the screening policy and on the sonographic detectability of GIO subgroups.

Congenital high airway obstruction syndrome and airway reconstruction: an evolving paradigm.

OBJECTIVES: To refine the classic definition of, and provide a working definition for, congenital high airway obstruction syndrome (CHAOS) and to discuss the various aspects of long-term airway reconstruction, including the range of laryngeal anomalies and the various techniques for reconstruction. DESIGN: Retrospective chart review. PATIENTS: Four children (age range, 2-8 years) with CHAOS who presented to a single tertiary care children's hospital for pediatric airway reconstruction between 1995 and 2000. CONCLUSIONS: To date, CHAOS remains poorly described in the otolaryngologic literature. We propose the following working definition for pediatric cases of CHAOS: any neonate who needs a surgical airway within 1 hour of birth owing to high upper airway (ie, glottic, subglottic, or upper tracheal) obstruction and who cannot be tracheally intubated other than through a persistent tracheoesophageal fistula. Therefore, CHAOS has 3 possible presentations: (1) complete laryngeal atresia without an esophageal fistula, (2) complete laryngeal atresia with a tracheoesophageal fistula, and (3) near-complete high upper airway obstruction. Management of the airway, particularly in regard to long-term reconstruction, in children with CHAOS is complex and challenging.

Congenital eruption cyst: a case report

Congenital pathologies are those existing at or dating from birth. Occurrence of congenital cystic lesions in the oral cavity is uncommon in neonates. Eruption cyst (EC) is listed among these unusual lesions. It occurs within the mucosa overlying teeth that are about to erupt and, according to the current World Health Organization (WHO) classification of epithelial cysts of the jaws, EC is a separate entity. This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction. Eruption of the teeth involved, primary central incisors, occurred at the fourth month of age. During this time neither the child nor mother had any complication such as pain on sucking, refusal to feed, airway obstruction, or aspiration of fluids or teeth.
