ABSTRACT
The interdisciplinarily developed German S2k AWMF guideline for the treatment of obstructive sialadenitis represents a new standard in the guideline program of the AWMF, the German Society for Consultants and the clinical disciplines working in the field of diseases of the head and neck region. In the last few years new diagnostic and therapeutic possibilities have been established in obstructive chronic Sialadenitis offering individually optimized therapeutic strategies. Only a few years ago extirpation of the whole affected gland was the only relevant therapy option. Nowadays therapeutic options such as interventional sialendoscopy and extracorporeal shock-wave lithotripsy (ESWL) are available in combination with marsupialization or incision of the duct. If possible the focus is on preserving the main glandular duct. In the following article the relevant aspects for the diagnostic radiologic procedures are presented.

A new and interdisciplinary S2k AWMF guideline for the treatment of obstructive sialadenitis has been published. There have been several technical achievements, for instance in the field of ultrasonography, via sialendoscopy, or by MR-sialography, that have increased the possibilities for diagnosis and treatment of patients with obstructive sialadenitis. In the past, the treatment of choice in case of unsuccessful medical treatment was a complete extirpation of the affected salivary gland. Nowadays, using a variety of modern treatment options (like sialendoscopy, or extracorporeal shock-waves lithotripsy sometimes combined with salivary duct incision), it is possible in most patients, especially in cases of sialolithiasis, to preserve the affected gland. A functional recovery after gland-sparing surgery is described but more data is needed to finally evaluate the long-time results. The new guideline describes all relevant steps to diagnose an obstructive sialadenitis and values all diagnostic tools critically. Finally, all recommendable therapy options are described and valued, too.

PURPOSE: Based on evaluation data from participant feedback, a concept was to be developed for introductory abdominal ultrasound courses lasting several days. This approach was to be developed incrementally with the intent of maximizing the learning effect per time. MATERIALS AND METHODS: This concept has been modified annually over several years based on the findings of educational research and the scores on final examinations in OSCE format. It has been modified with the aid of detailed questionnaires completed by approximately 2000 participating physicians and has thus undergone incremental optimization. RESULTS: Analysis of the most recent 1005 questionnaires has shown that participants recommend a modular course design with only brief lectures on theory (average optimal duration of 20 min., SD 9.6 min.). These should alternate with longer practical "hands-on" ultrasound exercises (60 - 90 min., accounting for at least 50 - 60 % of the course time), consolidating drawing exercises, and breaks. 51 % of the physicians specified 5 participants as the ideal group size for practical exercises, while 43 % specified only 4. The discussion presents 10 specific quality indicators for efficient ultrasound courses. It elucidates the feasibility and logistical prerequisites of this model, and compares it with other basic course concepts. Furthermore, this article presents a model for an evaluation covering the course concept and tutors as well as discussing a training program for tutors including a cost analysis. CONCLUSION: In summary, the participants estimate the course design to represent a mature concept that has demonstrated its feasibility and broad acceptance among physicians in CME.

Orbital pain can be provoked by diseases of the orbital skeleton as well as the maxillary sinus. Infections of the maxillary sinus caused by dental infections (e.g. periodontitis) or root canal treatment represent the majority of these cases followed by injuries of the orbital skeleton. An appropriate medical history usually provides indications for the further diagnostic procedure. In rare cases diseases of the facial skeleton as well as Wegener's granulomatosis can also cause orbital pain. In contrast temporomandibular disorders (TMD) may cause motility disorders and alterations in binocular vision but are not responsible for orbital pain.

The purpose of this study was to investigate how patients with maxillofacial defects evaluate their quality of life after maxillectomy and prosthodontic therapy with obturator prostheses. 43 patients were included in the study (25 female, 18 male). 31 (72%) patients completed a standardized questionnaire of 143 items and then answered additional questions in a standardized interview. Global quality of life after prosthodontic therapy with obturator prostheses was 64% (±22.9) on average. Functioning of the obturator prosthesis, impairment of ingestion, speech and appearance, the extent of therapy, and the existence of pain had significant impact on the quality of life (p<0.005). Orofacial rehabilitation of patients with maxillofacial defects using obturator prostheses is an appropriate treatment modality. To improve the situation of patients prior to and after maxillectomy sufficient information about the treatment, adequate psychological care and speech therapy should be provided.

Since 2008, a new polyomavirus (MCPyV) in Merkel cell carcinomas (MCC) has been described, but little is known about its impact on the clinical course. The purpose of this study was to determine the presence of MCPyV in a large sample and to correlate the results with the clinical course of the disease. 59 samples from 44 patients were analysed for the presence of MCPyV using the primers LT3, VP1 and LT1. The clinical records of these patients were evaluated and correlated with the presence of MCPyV. 58% of specimens were positive for MCPyV. Of these, LT3 was positive in 53%, VP1 in 37% and LT1 in 10%. 57% of primary tumours and 53% of metastases were positive for LT3; the numbers for VP1 and LT1 were lower. There was no correlation between the detection of MCPyV in the primary tumour and the appearance of metastases. The survival time was statistically independent from the presence of MCPyV. There is a striking occurrence of MCPyV in MCC, but whether it affects the clinical course remains unclear.

There is controversy over the frequency of dermoid cysts in the head and neck area. Some authors report that they are common, whereas others say that only 7% of such cysts occur in the head and neck area. In either case, they are extremely rare in the parotid gland. When PubMed is searched for 'dermoid cyst of the parotid gland', only 11 articles are listed. Only four of the articles written in English are case reports of dermoid cysts of the parotid gland. Due to the rarity of descriptions and the considerable diversity of swellings of the parotid gland diagnosis is difficult. Visualizing options like computed tomography, magnetic resonance imaging and ultrasound cannot give a conclusive preoperative diagnosis. This case report shows the challenges in diagnosis and gives a short review of the literature.

Distance estimation in prey catching was as exact in monocular toads (Bufo bufo (L.)) as in binocular ones. Application of Atropine or Miotic had no significant effect on binocular animals, whereas in monocular toads it made accurate distance estimation impossible. The accommodative state of the eye is decisive for depth estimation of monocular, but not of binocular toads.
