'Nasal mask' in comparison with 'nasal prongs' or 'rotation of nasal mask with nasal prongs' reduce the incidence of nasal injury in preterm neonates supported on nasal continuous positive airway pressure (nCPAP): A randomized controlled trial.

With increasing use of nCPAP, the safety and comfort associated with nCPAP have come into the forefront. The reported incidence of nasal injuries associated with the use of nCPAP is 20% to 60%. A recent meta-analysis concluded that the use of nasal masks significantly decreases CPAP failure and the incidence of moderate to severe nasal injury and stress the need for a well powered RCT to confirm their findings.

Nasalleukoplakia:update on diagnosis and management.

Nasal leukoplakia, defined as nasal mucosal grayish white lesion accompanied by adjacent mucosa thickening and hyperemia, is a kind of precancerous lesion. Since a case of nasal septum mucosal leukoplakia reported by Edley in 1955 and 62 cases of nasal leukoplakia reported by Liu Chun-Lin in 1964, few cases were reported. In this review, the pathogenesis, diagnosis and treatment of nasal mucosal leukoplakia are systematically summarized. Attention should be paid to this disease to reduce the possibility of ...

First-Trimester Diagnosis of Agnathia-Otocephaly Complex: A Series of 4 Cases and Review of the Literature.

First-trimester ultrasound findings in 4 fetuses with agnathia-otocephaly complex are described. In addition, information from 3 cases reported in the literature was also reviewed, for a total of 7 cases analyzed. All 7 fetuses presented with agnathia and 6 with ventrocaudal displacement of the ears (melotia/synotia). Four fetuses had holoprosencephaly. In 6 cases, the parents opted for termination of pregnancy. The remaining case resulted in premature delivery at 26 weeks due to severe polyhydramnios and e...

The most relevant chromosomal abnormalities in the north of rio Grande do Sul, Brazil: twenty-six years of cytogenetic analysis.

From 1992 to 2018, cytogenetic analyses were successfully performed to explore the chromosomal abnormalities of 729 patients, who utilised a pioneering counselling service in the city of Passo Fundo in the northern part of the Brazilian state of Rio Grande do Sul. This city is characterised by a large conglomerate of private and public hospitals. A classical cytogenetic analysis and G-banding were performed using the patient samples. Although normal karyotypes were observed for 562 of the cases, 167 individ...

An in-utero re-classification of umbilical-portal-systemic venous shunt (UPSVS) has recently been proposed. We retrospectively reviewed the sonograms of a large cohort of fetuses, identified and analyzed UPSVS cases, and presented the prenatal sonographic characteristics, birth outcomes, and follow-up results following the new classification system.Sonograms and clinical data of all participants who visited our departments from April 2016 to July 2018 were retrospectively reviewed. Identified cases of UPSVS...

Double chromosomal translocation in an infertile man: one-step FISH meiotic segregation analysis and reproductive prognosis.

The prevalence of chromosomal translocations is 1/500 in the general population. While in the vast majority of cases, carriers have a normal phenotype; they can present with difficulty conceiving due to the presence of a proportion of unbalanced gametes as a consequence of abnormal chromosomal segregation during meiosis. Since complex translocations involve three or more chromosomes, meiotic segregation leads to a greater number of possible combinations which effectively complicate both their study and ther...

Quantitative Estimation of the Effect of Nasal Mucociliary Function on In Vivo Absorption of Norfloxacin after Intranasal Administration to Rats.

Nasal drug delivery has attracted significant attention as an alternative route to deliver drugs having poor bioavailability. Large-molecule drugs such as peptides, and central nervous system drugs, would benefit from intranasal delivery. Drug absorption after intranasal application depends on the nasal retention of the drug, which is determined by the nasal mucociliary clearance. Mucociliary clearance (MC) is an important determinant of the rate and extent of nasal drug absorption. The aim of the present s...

Septal fractures predict poor outcomes after closed nasal reduction: Retrospective review and survey.

Duplicated distal phalanx of thumb or hallux in trisomy 13: A recurrent feature in a series of 42 fetuses.

Trisomy 13 or Patau syndrome (PS) is a well-known aneuploidy characterized by a polymalformative syndrome. We described a large series of fetuses with PS and compared them with cases described in the literature, most of which were live-born. In all, 42 fetuses, aged from 14 to 41 gestational weeks (GW), were examined. The main defects observed were similar to those described in live-born patients: congenital heart defects (76%), holoprosencephaly spectrum anomalies including arhinencephaly and hypotelorism ...

Therapeutic effect of nasal corticosteroids combined with nasal antihistamine on vasomotor rhinitis.

Epistaxis: Outpatient Management.

Epistaxis is a common emergency encountered by primary care physicians. Up to 60% of the general population experience epistaxis, and 6% seek medical attention for it. More than 90% of cases arise from the anterior nasal circulation, and most treatments can be easily performed in the outpatient setting. Evaluation of a patient presenting with epistaxis should begin with assessment of vital signs, mental status, and airway patency. When examining the nose, a nasal speculum and a good light source, such as a ...

Correlation Between the Existing Classifications of Nasal Bone Fractures and Subjective Patient Satisfaction.

Since the nose is at the center of the face, small changes to it can cause a big overall change. Therefore, a nasal fracture needs to be operated on when deformity is expected. Although many taxonomies have been developed for nasal bone fractures, no study has aimed to predict individual patient satisfaction. Herein, the authors tried to determine any correlation between the existing classifications of nasal bone fractures and subjective patient satisfaction. A retrospective study and telephone survey were ...

Large intraosseous lipoma of the skull:A case report and review of the literature.

Intraosseous lipomas occurring within the skull is rare. Currently, the known locations include frontal bone, parietal bone, temporal bone and ethmoid bone.
