    Abstract Varicella is the manifestation of primary infection with the varicella-zoster virus, mainly affecting preschool and school-aged children. The children suffer from a generalised, vesicular rash and fever. Despite the infection's typically non-threatening course, a variety of severe complications have been described.The authors present the case of a female infant suffering from varicella and developing preseptal cellulitis with a frontal abscess while being treated with intravenous antibiotics. Otorhinolaryngology consultation was sought since the clinical image was highly suggestive for sinusitis complications, namely orbital cellulitis and frontal bone osteomyelitis (Pott's puffy tumour). However, the child was below the age of frontal sinus development and there was no other apparent sign of sinonasal involvement. Ultrasonography revealed a mid-frontal collection without signs of abscess formation preseptally or postseptally, leading to the diagnosis of cutaneous superinfection of varicella lesions. The frontal abscess was drained, and the child fully recovered under antibiotic treatment.

    Abstract Background: Intracranial teratoma represents a rare neoplasm, occurring predominantly during childhood. Characteristic symptoms depend on the location but are mainly hydrocephalus, visual disturbances, hypopituitarism, and diabetes insipidus. Initial diagnosis can be challenging due to similar radiological features in both teratomas and other lesions such as craniopharyngiomas. Gross total resection is recommended if feasible and associated with a good prognosis.
    Case description: A 10-year-old girl presented with newly diagnosed growth retardation, fatigue, cephalgia and bilateral hemianopia. Further laboratory analysis confirmed central hypothyroidism and hypercortisolism. Cranial magnetic resonance imaging showed a cystic space-occupying lesion in the sellar and suprasellar compartment with compression of the optic chiasm without hydrocephalus present, suspicious of craniopharyngioma. Subsequently, an endonasal endoscopic transsphenoidal near-total tumor resection with decompression of the optic chiasm was performed. During postoperative recovery the patient developed transient diabetes insipidus, the bilateral hemianopia remained unchanged. The patient could be discharged in a stable condition, while hormone replacement for multiple pituitary hormone deficiency was required. Surprisingly, histopathology revealed conspicuous areas of skin with formation of hairs and squamous epithelia, compatible with a mature teratoma.
    Conclusions: We present an extremely rare case of pediatric sellar teratoma originating from the pituitary gland and a review of literature focusing on the variation in presentation and treatment. Sellar teratomas are often mistaken for craniopharyngioma due to their similar radiographic appearances. However, the primary goal of treatment for both pathologies is to decompress eloquent surrounding structures such as the optic tract, and if applicable, resolution of hydrocephalus while avoiding damage to the pituitary stalk and especially the hypothalamic structures. If feasible, the aim of surgery should be gross total resection.

    Abstract Primary Burkitt lymphoma of the thyroid is an extremely rare entity with only a few reported cases. A female patient in her 70s with Hashimoto's thyroiditis presented with a 2-month history of progressive left-sided neck swelling. Ultrasound examination revealed a multinodular goitre and fine needle aspiration (FNA) showed no signs of malignancy. The rapid growth of the thyroid mass raised the concern of a lymphoproliferative process. After left thyroid lobectomy and histopathological examination, the diagnosis of Burkitt lymphoma was made and the patient was included in a randomised study providing chemotherapy following a dose adjusted EPOCH-R regimen. Clinical remission was reached after 6 cycles of chemotherapy. There were no signs of relapse on follow-up, 1.5 years after the end of the treatment. Fast growing thyroid nodules in HT warrant a high index of suspicion. Despite no signs of malignancy after FNA cytology, these nodules may need further investigations.

    Abstract The efficiency of training visual attention in the central and peripheral visual field was investigated by means of a visual detection task that was performed in a naturalistic visual environment including numerous, time-varying visual distractors. We investigated the minimum number of repetitions of the training required to obtain the top performance and whether intra-day training improved performance as efficiently as inter-day training. Additionally, our research aimed to find out whether exposure to a demanding task such as a microsurgical intervention may cancel out the effects of training. Results showed that performance in visual attention peaked within three (for tasks in the central visual field) to seven (for tasks in the periphery) days subsequent to training. Intra-day training had no significant effect on performance. When attention training was administered after exposure to stress, improvement of attentional performance was more pronounced than when training was completed before the exposure. Our findings support the implementation of training

    Title translation Conservative and surgical rehabilitation of hearing loss.
    Abstract According to WHO 360 million people are hard of hearing. Hearing disorders are not only seen in elderly but also in children. Clinically we differentiate between hearing disorders concerning the transmission of sound from the outer ear to the cochlea (conductive hearing loss) and disorders with reduced sound perception concerning the inner ear an related structures (sensorineural hearing loss). This article summarizes common surgical and technical possibilities for rehabilitation. For each pathology we graphically illustrate the generic working principle of the rehabilitation including the indication range in an exemplary audiogram.
