A randomized trial of Rapid Rhino Riemann and Telfa nasal packs following endoscopic sinus surgery.

OBJECTIVES: To compare Telfa with the Rapid Rhino Riemann nasal pack for use following endoscopic sinus surgery. DESIGN: Prospective, randomized, double-blind, paired trial. SETTING: Tertiary otolaryngology hospital. PARTICIPANTS: Forty-five adult patients undergoing bilateral endoscopic sinus surgery for either chronic rhinosinusitis or nasal polyps. MAIN OUTCOME MEASURES: A visual analogue scale was used to assess discomfort caused by the presence of the packs in the nose and by their removal. The amount of bleeding was noted with the packs in place and following their removal. Crusting and adhesions were assessed 2 and 6 weeks following surgery. RESULTS: Both packs performed well giving good haemostasis and causing little bleeding on removal. Both packs caused only mild discomfort while in the nose. On the visual analogue scale of 0-10 cm the mean visual analogue score for Rapid Rhino Riemann pack was 1.7 and for Telfa 2.0 (P = 0.371). The Rapid Rhino Riemann pack caused significantly less pain on removal compared with the Telfa pack with a mean visual analogue score of 2.0 in comparison with 3.7 for Telfa (P = 0.001). There were less adhesions with the Rapid Rhino Riemann than Telfa pack but this was not statistically significant (P = 0.102). CONCLUSIONS: Both Telfa and Rapid Rhino Riemann packs can be recommended as packs that control postoperative haemorrhage, do not cause bleeding on removal and cause little discomfort while in the nose. The Rapid Rhino Riemann pack has the advantage of causing significantly less pain on removal.

A case of rhinoscleroma treated with ciprofloxacin.

Respiratory scleroma (often termed 'rhinoscleroma') is a chronic inflammatory condition in which deforming masses of tissue distend the nasal cavity. Klebsiella rhinoscleromatis is the causative agent of this infection and the Mikulicz cell is specific to the lesion being a large macrophage with clear cytoplasm containing the bacilli. Antibiotic therapy has traditionally consisted of streptomycin and tetracycline long-term but this presents problems with adverse side-effects and poor patient compliance. We report on a young patient with nasal rhinoscleroma who achieved resolution after treatment with oral ciprofloxacin. As mentioned in a review of patients with rhinoscleroma at the Mayo clinic in 1993, the fluoroquinolones deserve further study as potentially highly effective agents for this condition. Ciprofloxacin is convenient for oral administration and has few adverse effects. It achieves good tissue penetration, is concentrated in macrophages and may prove to be useful in the therapy of rhinoscleroma.

Topical corticosteroids in nasal polyposis.

Nasal polyps are the common end-point of a number of conditions characterised by inflammation and are rarely 'curable' in its true sense. After consideration of the underlying aetiology and confirmation of the diagnosis, they are normally managed by a combination of medical and surgical interventions. Of these, topical corticosteroids have proved to be the medical treatment of choice. The objectives of the medical management are to eliminate or reduce the size of polyps, re-establish nasal airway and nasal breathing, improve or restore the sense of smell, and prevent recurrence of nasal polyps. The mechanism of action of corticosteroids may be by a multifactorial effect on various aspects of the inflammatory reaction, the effect being initiated by their binding to a specific cytoplasmic glucocorticoid receptor. At a cellular level, there is a reduction in the number of antigen-presenting cells, in the number and activation of T cells, in the number of mast cells, and in the number and activation of eosinophils. When polyps are large (grade 3) topical medication is difficult to instil in a very blocked nose and surgery or short term systemic corticosteroids may be required. Topical corticosteroids are of use in the primary treatment of nasal polyps when they are of a small or medium size (grades 1 and 2) and in the maintenance of any therapeutic improvement. The efficacy of topical corticosteroids such as betamethasone sodium phosphate nose drops, beclomethasone dipropionate, fluticasone propionate and budesonide nasal sprays in reducing polyp size and rhinitis symptoms has been demonstrated in several randomised, placebo-controlled trials. Beclomethasone dipropionate, flunisolide and budesonide sprays have also been shown to delay the recurrence of polyps after surgery. Placebo-controlled studies of agents that have shown a significant clinical effect in the management of nasal polyposis are reviewed.

The effect of laser assisted uvulopalatoplasty on the sense of smell and taste.

AIM: To assess the effect, if any, of Laser Assisted Uvulo Palatoplasty (LAUP) on the sense of smell and taste. MATERIALS AND METHODS: A prospective study examined 33 patients undergoing LAUP for snoring. Significant sinonasal pathology was excluded in all patients by a complete examination including rigid nasal endoscopy. None of the cases had any systemic illness or drug history that was likely to affect the sense of smell or taste. Twenty-eight patients were male and five female. The mean age was 44 years (range, 25-67). Twelve patients (36%) were regular smokers, and eight patients (24%) were ex-smokers all of whom reported a change in smell and taste after stopping. Preoperative assessment utilised a visual analogue score of smell and taste perception, the University of Pennsylvania Smell Identification Test (UPSIT) for the assessment of olfaction (maximum score of 40), and whole mouth testing for solutions of NaCl, sucrose, quinine, citric acid and acetic acid. LAUP technique was standardised for each case and reassessment was performed 3 months postoperatively. RESULTS: Three patients failed to complete the study and were excluded. The mean values for visual analogue score pre and post surgery were 9.1 and 8.9 respectively, which was not significant using Wilcoxon Rank test (P = 0.257). The mean value of the UPSIT scores before surgery were 32.3 (+4.0), range, 24-39, and after surgery 31.2 (+4.3), range 20-37. There was no significant difference in pre and post UPSIT scores (p = 0.068). Whole mouth taste testing had a preoperative mean value of 4.1 and a postoperative value of 4.2. The difference was not statistically significant, Wilcoxon Rank test (p = 0.317). CONCLUSION: In this study there was no significant change in the patients' perception of smell and taste or in their objective measurement following a standardised Laser Assisted Uvulopalatoplasty.

Primary chordoma of the ethmoid sinus.

Primary chordoma of the paranasal sinuses are extremely rare tumours, with only a small number of cases verified and published in the literature. It appears that only five of these cases involved the ethmoid sinuses either as a primary or by local invasion, and of these documented cases only one other has been found to solely involve the ethmoid sinus. We present a case of primary ethmoid sinus chordoma treated by wide local surgical excision and present a review of the literature with regard to prevalence and treatment rationale.

Heterotopic pleomorphic adenoma of the external nose.

Pleomorphic adenomas arising from sites other than the major or minor salivary glands are uncommon. We describe a case of pleomorphic adenoma in the subcutaneous tissue of the nasomaxillary crease. An identical tumour was previously excised from the right nasal cavity. The possible aetiology of these heterotopic salivary gland tumours is discussed.

Management of middle ear myoclonus.

Tinnitus produced by synchronous repetitive contraction of the middle ear muscles (middle ear myoclonus) is a rare condition. We present six cases of middle ear myoclonus in whom different management regimes were successful. In two patients, the tinnitus was controlled by conservative measures. In one patient, whose tinnitus was associated with blepharospasm, significant improvement occurred following botulinum toxin injection into the ipsilateral orbicularis oculi. Three patients were cured by tympanotomy with stapedial and tensor tympani tendon section. The aetiology of this type of myoclonus remains unclear. The diagnosis is based on the history of involuntary and rhythmic clicking or buzzing tinnitus which is invariably unilateral. The primary differential diagnosis is palatal myoclonus whilst other local aural pathologies must be excluded by careful clinical assessment. Surgical section of these muscles via tympanotomy brings guaranteed relief when conservative measures fail.

Vile bodies: an endoscopic approach to nasal myiasis.

Nasal myiasis is the infestation of the nasal cavities by larvae (maggots) of Diptera flies. Several species of flies deposit their ova in the nose and the larvae feed on the host's tissues. We present a case of nasal myiasis by larvae of Oestrus ovis--Sheep Nasal Bot Fly. The larvae of Oestrus ovis are well known parasites in the nasal cavities and paranasal sinuses of sheep and goat. In Britain very rarely larvae may be deposited in the eye, nostrils or outer ear of man, usually husbandry workers. Reputedly, the larvae never survive beyond the first stage with acute catarrhal symptoms lasting only a few days. This is the first reported case in the UK of an urban-dwelling patient infected by mature, third instar larvae of O. ovis. His nasal infestation resolved after endoscopic removal of the live maggots.

Cytogenetic studies in 112 cases of untreated myelodysplastic syndromes.

Cytogenetic studies were performed in 112 untreated cases of myelodysplastic syndrome (MDS) between 1985 and 1990. Among 112 patients who were examined at the time of diagnosis, 54 had an abnormal karyotype (48%). The highest frequency of chromosome abnormalities was observed in refractory anemia with excess of blasts (RAEB) and RAEB in transformation (RAEB-t) and the lowest in refractory anemia with ring sideroblasts (RARS) and chronic myelomonocytic leukemia (CMMoL). Numerical changes were observed in 19 cases and structural in 17; chromosome 8 was most frequently gained (11 cases), whereas chromosome 7 was most frequently lost (6 cases), 5q- in 14 (4 as a sole anomaly); involvement of 7q22 was seen in 3 cases, 11p in 2 patients, 11q in 3 (one patient as a sole anomaly), 12p in 4 (2 patients as a sole anomaly), i(17q) in 4 (3 patients as a sole anomaly), and complex chromosomal defects in 10 patients. If one takes into account the prognosis value, a complex karyotype and the presence of ring chromosomes were correlated with the worst prognosis, followed by -7/7q-; an intermediate prognosis corresponds to i(17q), 12p as a sole anomaly, +8 (as a sole anomaly or plus other anomalies), and involvement of 12p. Patients with a 5q- as a sole anomaly or with a normal karyotype, had the best prognosis.

Cytogenetic evidence of involvement of an early progenitor myeloid cell in 4;11 translocation-associated acute leukemia.

The t(4;11)(q21;q23)-associated acute leukemia may show both lymphoid and myelomonocytic features, which suggests a pluripotent progenitor stem cell as the hematopoietic cell involved in this neoplastic process. However, there is no cytogenetic evidence to support this contention. We present a case of acute myelomonocytic leukemia (M4, FAB subtype) with t(4;11)(q21;q23), which was also found in several hypertetraploid metaphases probably corresponding to megakaryocytes. This confirms the cellular origin in an early progenitor myeloid cell of this type of acute leukemia.

Chromosome 5 abnormalities in acute lymphoblastic leukemia.

We report two cases of acute lymphoblastic leukemia with involvement of chromosome 5. One of them showed a del(5)(q13q33) in a 5-year-old boy who had previously received antineoplastic chemotherapy for an L1-ALL that had been diagnosed nine months before. The other one showed a t(5;7)(q12-13;q36) together with a t(8;14)(q24;q32) and a der(1) in a 66-year-old man with an L3-ALL. Both chromosome 5 aberrations are interpreted as evolutionary events. In the first case, it was secondary to chemotherapy treatment; in the second, an evolutionary chromosome rearrangement, considering the translocation between chromosomes 8 and 14 as the primary cytogenetic event.

11q23 abnormalities in children with acute nonlymphocytic leukemia (M4-M5). Association with previous chemotherapy.

Cytogenetic studies of 12 patients aged less than 14 years with acute nonlymphoblastic leukemia (ANLL) (M4-M5) showed structural abnormalities on chromosome 11 at band q23-q24 in five cases (41.8%). Four of these 12 patients had ANLL (M4-M5) after treatment with cytostatics for non-Hodgkin lymphoma in one case and for an acute lymphoblastic leukemia (ALL) in the other three. Three of these four cases had 11q23 abnormalities [one [one 46,XY,t(11;17)(q23;25); another 47,XY,+8,-15,del(11)(q23),+der(15)t(15;?)(p11;?); the third 47,XX,+8,t(3;17) (p11;q25),t(4;11)(q21;q23)] and one had a normal karyotype on being diagnosed ANLL (M4-M5). The notable increase of ANLL (M4-M5) in our patients who had received cytostatics as treatment for a previous neoplasia makes evaluation of our results timely in comparison with those of other groups who use these therapeutic protocols.

Cytogenetic study in six Spanish patients with Burkitt's lymphoma.

A cytogenetic study carried out on affected tissues of six children with Burkitt's lymphoma revealed five cases with a typical translocation (8q-; 14q+) and one with a variant t(2p-; 8q+). Additional cytogenetic variations were present in three cases. One had two acrocentric marker chromosomes comprised of material from chromosome #1 (1q21----q44) translocated to the Y gonosome. The other two cases had a cytogenetic alteration of chromosome #12. Cytogenetic studies carried out systematically in Burkitt's lymphoma could be a great help in possibly establishing differences in the biologic and clinical aspects of cases presenting with the t(8;14) versus cases with variant translocations, as this would allow for classification of these patients into groups which, at present, cannot be differentiated using other diagnostic methods.

Chromosome banding patterns in patients with chronic myelocytic leukemia.

One hundred and nine patients with Ph1-positive chronic myelocytic leukemia were cytogenetically studied with banding methods. Seventy-eight patients were studied in the chronic phase and 39 patients in the blastic phase. The standard translocation was present in 107 cases. Two patients showed complex translocations involving chromosomes No. 6, 9, 22, 11 and No. 9, 22, 11, respectively. Ph1-negative cells were detected in 8 cases (7%). Chromosome aberrations in addition to the Ph1 chromosome were observed in 6 cases (8%) during the chronic phase. The karyotypic findings during the blastic phase were similar to those reported in the past [trisomy 8, iso(17q), and a second Ph1]. The significance of Ph1-negative cells, the geographic heterogeneity of the chromosomal aberrations, the effect of chemotherapy on the appearance of new clones, and the importance of the materials and methods used for the comparison of cytogenetic patterns at different laboratories are discussed.
