[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.

[Hughes' operation and combined procedures]. / Operation nach Hughes und damit kombinierte Verfahren.

BACKGROUND: The Hughes procedure is a standard and widely used technique for lower eyelid reconstruction. This paper presents the results of 55 patients who underwent reconstruction of the anterior and posterior lamella with the Hughes procedure at the University eye clinic in Salzburg between 2002 and 2012. PATIENTS AND METHODS: This study included 55 patients who underwent lower eyelid reconstruction performed with the Hughes procedure including a full skin graft. In 95 % of patients (52/55) this method was performed after tumor resection. The defect size of the lower lid was at least 10 mm horizontally and ranged between 10 and 15 mm. Of the patients three were treated with a combined Hughes and Tenzel procedure whereas in five cases the Hughes procedure was combined with an autologous tarsoconjunctival flap of the contralateral upper lid and a local full skin rotational flap. RESULTS: In 42 out of 55 patients both the eyelid function as well as the restoration of good cosmesis could be achieved. In 6 out of the remaining 13 patients suffering from minor complications, the function and cosmesis were restored after secondary minor surgery or additional conservative treatment. For six patients, further reconstructive surgery was necessary and one experienced a major complication in the form of a recurrence of basal cell carcinoma necessitating exenteration. CONCLUSIONS: The Hughes procedure is a well-suited technique for eyelid reconstruction of shallow defects extending beyond 10 mm horizontally and involving up to 100 % of the eyelid. The latter require a combined procedure such as the Hughes procedure and an autologous tarsoconjunctival flap and skin graft.

Fatal aconitine intoxication or thyroid storm? A case report.

The case of a female in the latter half of her teens found dead in her father's apartment is reported. A glass containing liquid and plant remnants was found at the death scene. There were no indications of any intervention or the application of force by a third party. Autopsy showed unremarkable findings. Toxicological investigations revealed lethal doses of aconitine, a highly poisonous alkaloid and the major active compound of Aconitum napellus, in all specimens. Plant remnants were identified as A. napellus leaves by a botanist and toxicological examination of the liquid in the glass on site showed extremely high concentrations of aconitine. Additionally, laboratory results revealed that the young female was suffering from thyrotoxicosis factitia, an uncommon form of hyperthyroidism caused by misuse or overdosing of thyroid hormones in order to loose weight. A rare but serious and often fatal complication of hyperthyroidism is thyroid storm. Eventually the condition of thyroid storm due to thyrotoxicosis factitia could have contributed to the woman's death from aconitine poisoning.

Investigation of promoter variations in dendritic cell-specific ICAM3-grabbing non-integrin (DC-SIGN) (CD209) and their relevance for human cytomegalovirus reactivation and disease after allogeneic stem-cell transplantation.

Promoter variations in Toll-like receptor genes (n = 7) and genes encoding pathogen recognition and virus entry receptors (n = 7) were screened to detect any association with human cytomegalovirus (hCMV) reactivation and disease in patients following allogeneic stem-cell transplantation. Two single nucleotide polymorphisms (rs735240, G>A; rs2287886, C>T) in the promoter region of the dendritic cell-specific ICAM3-grabbing non-integrin (DC-SIGN) showed a significant association with an increased risk of development of hCMV reactivation and disease. Furthermore, these genetic markers influenced the expression levels of DC-SIGN on immature dendritic cells, as well as the infection efficiency of immature dendritic cells by hCMV, as determined by hCMV immediate-early antigen staining. Screening of patients following allogeneic stem-cell transplantation for the presence of these defined genetic polymorphisms might help to predict the individual risk of hCMV reactivation and disease.
