Local allergic rhinitis in children.

Local allergic rhinitis (LAR) is one of the endotypes of rhinitis. Despite much data about epidemiology diagnosis and treatment in adult patients with LAR, there is little information on children. Many studies indicate the need for such an assessment of the phenomenon in children, which results in one meta-analysis based on young patients selected from cohorts of patients of different ages.

House dust mite sublingual immunotherapy: a double-blind, placebo-controlled study in elderly patients with allergic rhinitis.

BACKGROUND: Immunotherapy in elderly patients is controversial, and there is still no evidence supporting this treatment's safety and efficacy in this population. This study was performed to evaluate the safety and efficacy of specific sublingual immunotherapy for house dust mite (HDM) allergens in patients over 60 years of age with allergic rhinitis and a confirmed allergy to HDM. OBJECTIVE: This study sought to assess nasal symptoms during HDM season, reduce medication use and monitor for adverse reactions during immunotherapy. METHODS: One hundred and eleven 60- to 75-year-old patients with allergic rhinitis and a confirmed Dermatophagoides pteronyssinus and Dermatophagoides farinae allergy were included in the study. The patients were individually randomized to active or placebo groups using a double-blind method (NCTO01605760 ClinicalTrials.gov). A total of 51 subjects in the sublingual allergen-specific immunotherapy (SLIT) group (Staloral 300R, Stallergenes, France) and 57 subjects in the placebo group were monitored for 3 years. RESULTS: Forty-seven patients completed 3 years of SLIT, and 48 subjects finished the placebo treatment in the same time period. The total nasal symptom score decreased by 44% in the active group and 6% in the placebo group after 3 years of SLIT. This difference was only significant in the active group (P < 0.05). At the end of therapy, the total medication score of the active group decreased significantly by a maximum of 51% (P < 0.05), whereas the total medication score of the placebo control group showed an insignificant decrease (P = 0.56). There were no systemic adverse reactions during the study. CONCLUSIONS & CLINICAL RELEVANCE: Sublingual allergen-specific immunotherapy in elderly patients with a HDM allergy to D. pteronyssinus and D. farinae generated a significant clinical improvement in the active group compared with the placebo group, particularly during the heating season. This therapy was well tolerated.

Endoscopic transsphenoidal treatment in recurrent and residual pituitary adenomas--first experience.

AIM OF THE STUDY: The aim of the study has been the assessment of the endoscopic method in the surgical management of recurrent and residual pituitary adenomas, as concerns treatment efficiency, substantial complications, and its possible advantages for the operating surgeon and patient. MATERIAL AND METHODS: In Department of Neurosurgery, Silesian University School of Medicine in Katowice, between October 2001 and June 2004, 125 patients underwent endoscopic surgery due to pituitary adenoma. The analysis comprised 20 patients, who were operated on due to recurrent adenomas or residual tumour not completely removed during the first surgical procedure. The group of patients was composed of 9 women and 11 men. The youngest patient was 32 years of age, the oldest 79. The average age was 53.9 years. The analysed group had 14 non-functioning adenomas, 4 GH-secreting adenomas, 1 PRL-secreting adenoma and 1 ACTH-secreting adenoma. 19 of them were macroadenomas while 1 was a microadenoma. 11 of the 20 adenomas infiltrated the cavernous sinuses. The surgical procedures were performed by a stable team, composed of 2 neurosurgeons, a laryngologist and an anaesthesiologist. The surgery method was based upon the technique developed by Jho and Carrau, with own modifications of the operators. A rigid neuroendoscope having the diameter of 4 mm with 0 degrees and 30 degrees optics by Storz was used. The follow-up period after surgery was between 12 and 42 months, 24.2 months on average. RESULTS: Of the 20 cases, complete recovery was achieved in 40% of patients undergoing secondary surgical procedures. In the group of 11 patients with adenomas not infiltrating the cavernous sinuses, recovery was reported for 8 of them, that is 73%. No fatalities occurred. 7 cases of liquorrhoea occurred during operation, requiring reconstruction and sealing of the sella by means of tissue glue and artificial dura or freeze-dried human dura. In 1 case, despite the application of post-operative lumbar drainage, rhinorrhoea occurred one month after the procedure, which required endoscopic reconstructive treatment. In the same patient, a pneumoencephalocele was observed. The average time of the repeat surgical procedure using endoscopic techniques was shorter by 18 minutes than the repeat procedure using microscopic techniques. CONCLUSIONS: The endoscopic method is a safe, hardly invasive and efficient surgical technique in the treatment of recurrent and residual pituitary adenomas. Advantages which add to its attractiveness are also reduction of the procedure duration, very good visualisation of the operative field, absence of serious complications, less pain experienced after the surgery.

Endoscopic transsphenoidal treatment of empty sella turcica syndrome using a silastic coil.

An empty sella turcica is due to the presence of an arachnoid diverticulum with its fluid content in the sella turcica, exerting pressure on the pituitary gland. In most cases this condition has an asymptomatic course, and is discovered by accident. Some patients, however, develop empty sella turcica syndrome with headaches, mild dishormonose, dysopsia and, rarely, spontaneous rhinorrhoea. Surgical treatment of empty sella turcica consists of filling the sella, through the transsphenoid route, with tissues collected from the patient or with artificial material. The aim of this report is to present our own experience of endoscopic extradural sella elevation using a silicone spiral, in 4 patients with primary empty sella turcica syndrome. The main indication for surgery was progressing dysopsia. The microinvasive endoscopic transsphenoidal method has been used, based upon the Jho technique with our own modifications. For the elevation of the sella, we used a coiled section of a Pudenz valve intraventricular silicone drain, adjusting its size to the dimensions of the operated sella. Both the implantation of the helix, and the postoperative course were uncomplicated for all surgically treated patients. The follow-up of several months confirmed improvement of the dysopsia in all surgically treated patients. MR examinations confirmed the correct location of the silicone spiral placed in the sella. It seems that the good results achieved are due to a correct indication for surgical treatment. The follow-up period ranges from 12 to 30 months and, so far, the clinical improvement is stable and satisfying both for the patients who underwent treatment and for the neurosurgeons.

Endoscopic transnasal transsphenoidal treatment of pathology of the sellar region.

From October 2001 to the end of November 2002 in Department of Neurosurgery, Silesian University School of Medicine in Katowice 70 explorations of the sella turcica were executed using the endoscopic method. In 63 cases the operation was done because of pituitary gland adenomas. In one case the diagnosis was craniopharyngioma, in 1 chordoma of the clivus, in one glioma of the optic nerve, in 1 the reason for an operation was an empty sella syndrome and in 3 cases the pathological diagnosis was an amorphous masses. Patients were operated using the 4-mm diameter endoscope with 0- and 30-degree angled lenses, using the method according to Jho and Carrau with our own modifications. In all cases of adenomas the total removal of the tumour was obtained in 71.4 %. Permanent diabetes insipidus occurred in 4.3 % of all operated patients. In our series of patients we did not observe any postoperative CSF leak or rhinological complications. One patient died, corresponding to 1.4 % of all cases. We the recommend transsphenoidal transnasal endoscopic approach for use in the cases of sellar region pathology because of the advantages of the method for surgeon and for comfort of the patient.

The authors report a rare case of the occurrence of the paradoxical CFN rhinerrhea in a three months after epidermal cyst of the cerebellopontine region removal. The good result of the surgical fistula obliteration was reached by using muscle graft and tissue glue.

[Correlation between symptoms and results of rhinomanometric measurements of nasal patency in patients with seasonal allergic rhinitis]. / Zwiazek miedzy samopoczuciem a wynikami rinomanometrycznych pomiarów droznosci nosa u chorych na sezonowy niezyt nosa.

The aim of presented study were to assess the usefulness of rhinomanometry in monitoring course of disease and effectivity of treatment in seasonal allergic rhinitis (SAR) through answering the question whether and eventually which relationship exists between patient's general feeling and results of rhinomanometric measurements of nasal patency (NP). The study involved 114 subjects with SAR divided into 3 groups dependent on phase of disease and severity of complaints and 30 healthy volunteers. For results see table I. Nasal flow and resistance measured at differential pressure 75 Pa in groups I, III and IV did not differ significantly. In group II nasal flow values were lower (alpha < 0.001) and resistance values higher (alpha < 0.001) as compared with remaining groups. Thus, the beginning of symptoms is related to lowering of NP as compared with symptom-free phase of SAR. In the symptom-free period NP do not differ from healthy population. The results of rhinomanometric measurements of NP are useful in monitoring of course of SAR in assessment of effectivity of treatment.

[The transseptal approach in transsphenoidal surgery of pituitary neoplasms]. / Dojscie przez przegrode nosowa w operacjach transsfenoidalnych guzów przysadki mózgowej.

The authors described the direct transseptal approach in transsphenoidal surgery for hypophyseal tumors. This route gives a good insight into the area of the sella. The above mentioned method is also less destructive to nasal structures in the nasal cavity, because preserves the anterior nasal septum. It is uniformity of actually views of rhinological school. 20 patients were operated using this method and none of them noticed the changes of nasal airway and the sense of smell.
