[Importance of machine blood count in the diagnosis of infectious mononucleosis by EBV]. / Stellenwert des maschinellen Blutbildes bei der Diagnose der infektiösen Mononukleose durch EBV.

INTRODUCTION: EBV serology is recommended for serological diagnosis of mononucleosis. As results of an automated differential blood count is available more quickly, possible differences between an EBV primary infection and a bacterial tonsillitis were investigated. METHODS: A retrospective evaluation of absolute and relative lymphocyte and monocyte counts of n = 140 patients > 16 years from 01/2008 to 01/2019 (mean age 21.4 years, 51 % ♀, 49 % ♂) with suspected EBV infection was performed. The groups of a serologically confirmed or excluded EBV infection were compared. RESULTS: An automated differential blood count was available in n = 42 patients with primary EBV infection. Average lymphocyte count was 5.5 ±â€Š2.6 giga/l. Patients with acute bacterial tonsillitis (n = 36) had significantly lower values with 1.6 ±â€Š1.3 giga/l, p < 0.05. Equal results were found in relative lymphocyte counts (47.4 ±â€Š17.9 vs. 12.8 ±â€Š9.1 %, p < 0.05). For monocyte counts, neither absolute (1.2 ±â€Š0.8 vs. 1.2 ±â€Š0.6 giga/l, p = 0.617) nor relative (8.8 ±â€Š3.6 vs. 9.8 ±â€Š5.2 %, p = 0.746) monocyte counts showed significant differences. CONCLUSION: Increased lymphocyte counts in an automated differential blood count can be a first indication of primary EBV infection. Perhaps up to 30 % morphologically altered lymphocytes are increasingly counted correctly with modern hematology analyzers and no longer counted as monocytes. These results could be used to make decisions about further diagnosis (abdominal ultrasonography, ECG) and antibiotic therapy before results of EBV serology are available.

[The KINDL questionnaire for assessment of general quality of life in adenotonsillar hyperplasia]. / Der KINDL-Fragebogen zur Erfassung der allgemeinen Lebensqualität bei adenotonsillärer Hyperplasie.

BACKGROUND: There are few systematic studies on the general quality of life of children before and after adenoidectomy and adenotonsillotomy, although interventions on adenoids and tonsils are the most frequent operations in childhood in Germany. For this reason, the established KINDL questionnaire was used to assess the quality of life of children for the first time. METHODS: Study participants (n = 111) and a waiting design control group (n = 35) were recruited consecutively from children (3-6 years) receiving adenoidectomy (66 %) or adenotonsillotomy (34 %). The Kiddy-KINDL® questionnaire was answered by parents on the day of surgery and 3.5 months postoperatively. Parents of the control group were interviewed, when the date of operation was scheduled and on the day of operation. RESULTS: Total scale score of the Kiddy-KINDL of max. 100 points improved slightly in the intervention group from preoperatively 75.9 ±â€Š10.8 (95 %-KI [73.8-77.9]) to postoperatively 77.2 ±â€Š9.2 points (95 %-KI [75.1-79.0]; p = 0.365). Also in the comparison group there was no significant change over time (77.9 ±â€Š9.7; 95 % CI [74.1-81.7] vs. 77.3 ±â€Š11.3; 95 % CI [72.8-81.8]; p = 0.949) or compared to the preoperative score of the intervention group (p = 0.894). The subscales scores for "physical well-being" (p < 0.01), "school" (p = 0.034) and "parents" (p < 0.01) showed significant improvements for the intervention group. Children with additional tonsillotomy also showed a significant postoperative increase of the total scale score (p = 0.049). CONCLUSION: The version of the Kiddy-KINDL we used is therefore not fully suitable for recording the general QOL in adenotonsillar hyperplasia, since an improvement in QOL could only be recorded in subscales. However, since tonsillotomy in particular seems to have a relevant influence on QOL, it should be performed in children with significant hyperplasia.

[Analysis of facial asymmetry in patients with crooked noses]. / Analyse von Gesichtsasymmetrien bei Patienten mit Schiefnasen.

BACKGROUND: Surgical management of crooked nose is challenging even for experienced rhino surgeons, although numerous techniques for correction have been described. Not infrequently, there is a facial asymmetry in addition to the crooked nose influencing the aesthetic results of the operation. Therefore, the purpose of this study was to determine how often there is an asymmetry of the face in addition to a crooked nose. MATERIAL AND METHODS: Retrospectively the data of 607 patients with a crooked nose (304 women, 303 men, mean age 30 years) were evaluated. The preoperative photos of the face were anthrometrically assessed based on angle measurements. RESULTS: 382 of the 607 patients had a c-shaped (63 %) and 225 an i-shaped (37 %) crooked nose. More than three-quarters of the patients had facial asymmetry in respect to the connecting line of the pupils and nasal base line. 49 % of patients reported a history of nasal trauma, but this had no relevant influence on the frequency of facial asymmetry. CONCLUSIONS: Pre-existing facial asymmetry is very common in patients with crooked nose and can significantly affect the aesthetic outcome of nasal surgery. This should be addressed as part of the informed consent. In particular, it should be mentioned that the surgical outcome can remain below the patient's aesthetic expectations. Not rarely, a revision surgery may be necessary.

[Adaptation of the "Nasal Obstruction Symptom Evaluation" (NOSE©) questionnaire in the German language]. / Erstellung einer deutschen Version des "Nasal Obstruction Symptom Evaluation" Fragebogens (NOSE©).

OBJECTIVE: The standardized and validated English NOSE© questionnaire is used to assess subjective complaints of nasal obstruction. The aim of our study was to create and validate a German version of the NOSE© questionnaire. MATERIAL AND METHODS: The original questionnaire was translated into German in multiple steps. The English back translation was sufficiently similar to the original questionnaire. Next, the translated questionnaire was completed twice each by a group of patients with symptoms of nasal obstruction (n = 76) and a group of nose healthy test persons (n = 104). Subsequently, the questionnaire was tested for internal consistency, test-retest reliability, construct validity, discriminant validity and sensitivity to change. Additionally, it was examined whether the rhinomanometric results of the patient group correlated with their questionnaire scores. RESULTS: The created German NOSE questionnaire had high internal consistency with an average result of Cronbach's α ≥ 0.8. The test-retest reliability was also satisfactory with Goodman-Kruskal-γ = 0.826. The discriminant validity showed significant differences between the patient and control group. Furthermore, sensitivity to change was high. The patients' rhinomanometric results before operation did not correlate with the corresponding NOSE questionnaire Scores. CONCLUSIONS: The study showed that the created German Version of the NOSE© questionnaire (NOSE GAV) is a valid method for assessment of subjective nasal obstruction. It can be used throughout German-speaking areas without restriction.

[Symptoms and parental expectation in adenoidectomy and adenotonsillotomy in preschool children]. / Hauptsymptome und Elternerwartung bei Adenotomie und Adenotonsillotomie im Vorschulalter.

OBJECTIVE: In this study, symptoms associated with adenoids and hyperplasic palatine tonsils and parental expectation of surgical outcome were recorded, to provide realistic parental information prior to adenoidectomy (AT) ± tonsillotomy (ATT). MATERIAL AND METHODS: In total n = 111 children (3-6 years, ♂ 65 % ♀ 35 %) were recruited, who received AT (66 %) or ATT (34 %) at ENT University Hospital Ulm. By questionnaire-based survey, the most common symptoms and the main reason for the operation were reported from parent's perspective (operation day, follow-up: 3.5 months). Results were visualized in bar charts for total collective and AT and ATT surgical groups (significance level α = 5 %). RESULTS: Most commonly, parents observed signs of respiratory problems (mouth breathing 87 %, nasal obstruction 86 %, snoring 78 %), hearing loss (68 %) and infection of upper airways (66 %). Nasal obstruction (77.5 %) and hearing loss (53.2 %) were the main reasons for operation. In children with pharyngeal tonsil hyperplasia only, hearing problems dominated, while in additional tonsillotomy, nocturnal apneas were the most frequently reported reason for surgery. For all symptoms, a significant postoperatively improvement was achieved. CONCLUSIONS: With a differentiated indication for surgery, it is possible to inform the parents about a very good and realistic and effective reduction of symptom after AT and ATT.
