Skull Base Fracture or Abuse Suspicion Based on Intraorbital Lymphangioma Secondary to Periorbital Hematoma.

Intraorbital lymphangiomas are among the orbital tumors that can cause sudden eye protrusion in children. In children with periorbital hematoma (panda eye sign), a skull fracture or abuse is likely first considered as the differential diagnosis. A 7-month-old boy presented to the ophthalmologist with complaints of swelling of the right upper eyelid, subconjunctival hemorrhage on the right ear side, and periorbital subcutaneous hemorrhage, which had appeared since the morning of the day before the visit. The eyeball did not protrude. Based on the interview and clinical findings, right eyeball contusion was suspected. The patient was then followed up for observation. Later, during the physical examination, the abovementioned symptoms were noted. Hence, the patient was admitted for a close examination based on the suspicion of skull base fracture and abuse. Contrast-enhanced magnetic resonance imaging (MRI) after admission revealed a multifocal cystic structure within the right intraorbital muscular cone. Thus, he was diagnosed with right intraorbital lymphangioma. Intraorbital lymphangioma may not show ocular protrusion, and this disease should be considered in cases where abuse is suspected, considering the periorbital subcutaneous hemorrhage.

A Boy Presenting with a Fever and Pancytopenia Diagnosed with Systemic Lupus Erythematosus without a Positive Anti-ds-DNA Antibody Result or Hypocomplementemia: A Case Report.

BACKGROUND: Hematological involvement, including anemia, leukopenia, lymphopenia, and thrombocytopenia, is one of the most common manifestations of childhood-onset systemic lupus erythematosus (cSLE). Specifically, relatively severe forms of hematological involvement, such as macrophage activation syndrome (MAS) and thrombotic microangiopathy, occur in the course of the disease. Positivity for anti-double stranded-DNA (ds-DNA) antibody and hypocomplementemia are important as not only criteria of diagnosing cSLE but also in the determination of the disease activity. CASE REPORT: A 13-year-old boy without pre-existing disease was referred to our hospital chiefly complaining of a fever for > 7 days, long-lasting malaise, nausea, and non-malar face rash. His blood examination showed pancytopenia and hyperferritinemia, but positive results for anti-ds-DNA antibody and hypocomplementemia were not recognized. Bone marrow aspiration revealed no evidence of malignant diseases, hemophagocytic lymphohistiocytosis, or MAS. A renal biopsy for the differential diagnosis of proteinuria and hematuria revealed class IIIa +V lupus nephritis, leading to the diagnosis of cSLE. CONCLUSIONS: It is important for cSLE to be considered in patients with pancytopenia, even those without positive anti-ds-DNA antibody findings or hypocomplementemia, and for aggressive approaches to be adopted for the differential diagnosis, including a renal biopsy.

Effect of Post-nasal Drip on Overnight-cough Frequency and Cough Pattern in Children with Asthma.

OBJECTIVE: In children, post-nasal drip (PND)-induced cough is speculated. However, the relationship between PND and cough is still unclear. METHODS: During acute exacerbation of asthma, the number of overnight coughs and the cough pattern were compared in the children with atopic asthma with PND (n = 8) and the children with atopic asthma without PND (n = 27). All subjects had allergic rhinitis according to our original cough monitor. RESULTS: The total number of overnight coughs was significantly higher in the subjects with PND than in the subjects without PND (P < 0.05). In contrast, the overnight cough pattern of the subjects with PDN was found to be the same as in the subjects without PND, showing an increase in the number of coughs at the sleep onset and in the early morning. CONCLUSION: Our results suggest that PND may increase the number of nighttime coughs in children with atopic asthma and allergic rhinitis. In contrast, the overnight cough pattern was the same in the two groups, suggesting that this specific cough pattern is due to allergic inflammation of the upper and lower airways.

Breath sound analyses of infants with respiratory syncytial virus acute bronchiolitis.

INTRODUCTION: The reliability of a breath sound analysis using an objective method in infants has been reported. OBJECTIVE: Breath sounds of infants with respiratory syncytial virus (RSV) acute bronchiolitis were analyzed via a breath sound spectrogram to evaluate their characteristics and examine their relationship with the severity. SUBJECTS AND METHODS: We evaluated the inspiratory and expiratory breath sound parameters of 33 infants diagnosed with RSV acute bronchiolitis. The sound powers of inspiration and expiration were evaluated at the acute phase and recovery phase of infection. Furthermore, the relationship between the breath sound parameters and the clinical severity of acute bronchiolitis was examined. RESULTS: Analyses of the breath sound spectrogram showed that the power of expiration as well as the expiration-to-inspiration sound ratio in the mid-frequency (E/I MF) was increased in the acute phase and decreased during the recovery phase. The E/I MF was inversely correlated with the SpO2 and positively correlated with the severity score. CONCLUSION: In infants with RSV acute bronchiolitis, the sound power of respiration was large at the acute phase, significantly decreasing in the recovery phase. In 61% of participants, nonuniform, granular bands were shown in the low-pitched region of the expiratory spectrogram.
