[Results of dacryocystorhinostomy according to Toti from 2000 to 2012]. / Ergebnisse der Dacryozystorhinostomie nach Toti im Zeitraum von 2000 bis 2012.

BACKGROUND: The aim of this study was to describe the efficiency, long-term success, patient satisfaction and recurrence rate after dacryocystorhinostomy according to Toti in a retrospective analysis. MATERIAL AND METHODS: At the Eye Clinic of the Paracelsus Medical University Salzburg 188 eyes of 176 patients with stenosis/obstruction of lacrimal duct were surgically treated between January 2000 and December 2012. Of these patients 173 eyes had no surgery before DCR according to Toti and 15 eyes had already been operated with diverse dacryocystorhinostomies. All patients underwent dacryocystorhinostomy according to Toti. Pre- and postoperative clinical finings were analysed retrospectively. Postoperative long-term results regarding patient satisfaction, absence of inflammation, epiphora and annoyance through local scar building had been evaluated with a questionnaire in a cross-sectional analysis. RESULTS: The primary success rate of DCR according to Toti was 91,9 % and the secondary success rate 98,3 % in patients without surgery preoperatively. Classifying by localisation of stenosis, better results could be reached in patients with postsaccal stenosis/obstructions (94,3 %) than in those with presaccal obstructions (77,8 %) or with mixed pre- and postsaccal stenosis/obstructions (86,7 %). Also in the patient group with previous surgery primary and secondary success rates of 93,3 % could be achieved after DCR according to Toti. CONCLUSIONS: This study confirms that DCR according to Toti is a highly successful technique minimising epiphora and discomfort. The best success rate was found in patients with postsaccal stenosis/obstructions. The local scar was not found to be disturbing.

[Transplants from the hard palate: method for mucosal graft reconstruction of the upper eyelid]. / Transplantate vom harten Gaumen: Methode zur Schleimhautrekonstruktion im Oberlid.

BACKGROUND: Mucosal grafts from the hard palate for reconstruction of the posterior lamella of the upper eyelid were compared for three different indications. The plastic reconstruction of the upper eyelid was carried out in patients with symblepharon and upper eyelid entropion following an autoimmune disease, in patients with subtotal or total upper eyelid resection due to a neoplasm and in patients with mucous membrane trauma using autogenous mucosal grafts from the hard palate. PATIENTS: In this retrospective comparative interventional case series 23 eyes from 19 patients were included in whom upper eyelid reconstruction was undertaken at the University Eye Hospital in Salzburg between 2001 and 2012. Reconstruction with hard palate grafts was performed in 5 eyes following extensive tumor resection, in 5 eyes of 3 patients after autoimmune diseases and in 13 eyes of 11 patients following trauma rehabilitation. RESULTS: In the total collective of patients who underwent upper eyelid reconstruction with hard palate grafts, no graft rejection or loss of graft occurred. Hard palate grafts are useful for reconstruction after tumor surgery in addition to other techniques in order to achieve good functional and esthetic results. For patients suffering from autoimmune disease (e.g. ocular pemphigus and Stevens-Johnson syndrome) the use of hard palate grafts was found to be equally useful, although results can possibly deteriorate over time due to the underlying disease. Hard palate grafts were shown to be very useful in reconstruction of the upper eyelid for correction of entropium due to symblepharon and distichiasis following thermal and chemical burns. CONCLUSION: Hard palate grafts are suitable as mucosal grafts replacing conjunctiva in systemic disease and are equally effective in the treatment of traumatic upper eyelid defects - such as defects after tumor surgery.

[Granular cell tumors of the orbit: diagnostics and therapeutic aspects exemplified by a case report]. / Granularzelltumor der Orbita: Diagnostische und therapeutische Aspekte anhand eines Fallberichtes.

BACKGROUND: Granular cell tumors (Abrikossoff's tumor) are very rare, mostly benign tumors of neurogenic origin which preferentially occur in the upper aerodigestive tract. Granular cell tumors rarely originate in the orbit and are therefore a diagnostic and therapeutic challenge. METHOD AND PATIENTS: A 42-year-old male patient presented to the Orthoptic Department of the University Eye Clinic in Salzburg with motility disturbances and diplopia in the right eye. The clinical examination revealed right-sided exophthalmos and shrinking of the choroid and retina due to a retrobulbar mass. The radiological examination showed an infiltrative tumor 1.7 × 1.3 cm in size in the lower temporal quarter of the orbit. Due to the localization a sonographically controlled fine needle puncture was carried out for preoperative diagnostics by a specialist in clinical cytology. The cytological examination confirmed the presence of a granular cell tumor. The tumor was excised via a conjunctival access route. RESULTS: Motility testing in the postoperative course control showed an improvement in the findings and the exophthalmos was clearly regressive. Vision improved from 0.5 preoperatively to 1.0 postoperatively. During the postoperative observational period of 12 months no recurrences occurred. Clinical control examinations are planned every 3 months and imaging controls every 6 months. CONCLUSION: Granular cell tumors of the orbit should be included in the differential diagnostics of orbital tumors despite the low incidence. A sonographically controlled fine needle puncture is an adequate procedure with respect to the diagnostics and further therapy for poorly differentiated tumors of the orbit with a suspicion of infiltrative growth and for which in toto resection is questionably possible. A complete surgical excision should be the aim of treatment of granular cell tumors. Continuous clinical and imaging control is necessary to enable early recognition of recurrences.

[Bartter's syndrome, chondrocalcinosis and hypomagnesemia]. / Syndrome de Bartter, chondrocalcinose et hypomagnésémie.

In two cases of Bartter's syndrome with hypomagnesaemia the authors report radiological findings typical of chondrocalcinosis associated with joint symptoms corresponding to this condition. In Bartter's syndrome there is, in addition to hypokalaemic alkalosis, often concomitant magnesium depletion which has marked repercussions with respect to both physiopathology and symptomatology. In particular, hypomagnesaemia could well be important in the pathogenesis of chondrocalcinosis through two simultaneous mechanisms: by reducing the activity of pyrophosphatases and by facilitating the crystallisation of pyrophosphates. These mechanisms could explain the association of Bartter's syndrome and chondrocalcinosis, which is described here for the first time.
