Factors associated with clinical outcomes in acute otitis media.

Acute otitis media (AOM) is a common disease in childhood. If predictors of outcome in AOM were known, it would be possible to individualize therapy. Our aim was to identify factors that predict the outcome in AOM. We enrolled 368 children with AOM (ages, 10 to 86 months). The severity of symptoms and the severity of tympanic membrane changes were graded with a scoring system. Nasopharyngeal colonization with middle ear pathogens was determined on day 1. Three outcomes were assessed: persistence of symptoms at day 5, persistence of tympanic membrane changes at day 28, and recurrence of acute symptoms prior to day 28. Persistence of symptoms at day 5 was associated with younger age (35 versus 44 months; p < .001), higher symptom score on day 1 (3.5 versus 2.9; p < .05), and colonization with Streptococcus pneumoniae (61% versus 41%; p < .05). Persistence of tympanic membrane changes at day 28 was associated with younger age (39 versus 45 months; p < .01), higher tympanic membrane score on day 1 (4.1 versus 3.6; p < .01), and nasopharyngeal colonization with S. pneumoniae, especially drug-resistant S. pneumoniae (33% versus 13%; p < .05). Recurrence of acute symptoms prior to day 28 occurred in 14% of the children. Streptococcus pneumoniae was the only pathogen associated with an increased recurrence rate (23%) as compared to the group without pathogens (7%; p < .05). Age, severity of disease at presentation, and nasopharyngeal colonization patterns were proven to be important determinants of outcome in AOM.

Subjective scoring of cough in children: parent-completed vs child-completed diary cards vs an objective method.

Cough is often used as an outcome measure, although the reporting of cough is unreliable. Using a 24 h ambulatory cough meter to measure cough frequency, the aim of this study was to compare: 1) the correlation of child-completed diary cards to the objective measurement, with that of parent-completed diary cards; and 2) the visual analogue scale (VAS) to the verbal category descriptive (VCD) score. The cough meter consisted of a previously validated Holter monitor and a cough processor. Eighty four children (39 with recurrent cough and 45 controls, aged 6-17 yrs) used a cough meter at least once. Thirty three subjects used the cough meter twice. Parents and children completed separate diary cards using the VAS and VCD scores. The strength of the relationship between the subjective scores and the objective recordings was analysed by spearman's rank correlation coefficient. For daytime cough, child-completed diary cards and the VCD correlated better to the objective measurement than parent-completed diary cards and the VAS, respectively. In subjects that used the cough meter twice, the difference between the cough frequency correlated to the difference in the subjective scores. The confidence intervals for the correlation coefficients were wide. The agreement between the objective and subjective presence of daytime cough was good but that for night-time cough was poor. We conclude that the severity of cough defined on diary cards may not represent cough frequency. Objective readings are first choice but currently not yet practical. The verbal category descriptive diary card completed by children and assisted by parents has the highest correlation to cough frequency measured objectively.

[Transpedicular reconstruction of vertebral body height with simultaneous interbody spondylodesis].

BACKGROUND AND PURPOSE: Surgical treatment of traumatic spinal injury should include fast and complete decompression of spinal cord and radices wits reduction of broken vertebral body, restoration of physiological spinal curvatures and spondylodesis of injured segments. Restoration of natural spinal curvatures is only possible when the height of broken vertebral body is reconstructed. MATERIAL AND METHODS: Between 1992 and 2001, 75 patients were operated on because of traumatic injuries of thoracolumbar spine in the Ortopaedic and Traumatology Department Skubiszewski Medical University of Lublin. 48 patients had broken vertebral body reduction with simultaneous filling of bone loss with autogenic bone grafts inserted through pediculum. Only in 4 cases posterior spondylodesis was carried out on arches and spinous processes. Transpedicular plasty of 44 broken vertebral bodies was connected with posterior interbody fusion with PLIF technique using graft application to interbody space. RESULTS: The operative protocol presented above allowed for the height of the anterior vertebral wall to be restored on average to 81.5% of the original height. We did not observe either fatigue breakage of the screws or screws loosening with kyphosis recurrence. We did not note serious postoperative complications, including neurological compromise. The operative procedure did not significantly change the neurological status of the patients. In 9 cases we noted neurological improvement: usually by 1 or 2 grades in Frankel's score. CONCLUSIONS: Restoration of the fractured vertebral body with bone grafts combined with posterior interbody spondylodesis effectively prevents the recurrence of the kyphotic deformation.

Interobserver variability in the radiological assessment of response to chemotherapy in glioma.

OBJECTIVE: To assess the interobserver variability in the radiologic assessment of response to chemotherapy in patients with recurrent glioma. METHODS: Five clinicians with experience in the treatment and follow-up of patients with glioma measured tumor size in 20 pairs of CT and 20 pairs of MRI scans of 35 patients who had been treated with chemotherapy for recurrent glioma. Tumor size was defined as the product of the two largest perpendicular enhancing tumor diameters on the postcontrast images. To assess the interobserver variability in the measurements of tumor size, and in the classification according to the widely used Macdonald response criteria, intraclass correlation coefficients (ICC) and weighted kappa values were calculated. RESULTS: Substantial interobserver agreement was noted in the manual, two-dimensional measurements of tumor size on CT and MRI in patients treated with chemotherapy for recurrent glioma (overall ICC 0.64). Classification of response to chemotherapy according to the Macdonald criteria resulted in moderate interobserver agreement (overall weighted kappa 0.51). In 65% of evaluated CT and in 55% of evaluated MRI studies, no complete consensus was found for the categorical tumor response measurement. CONCLUSION: The radiologic assessment of response to chemotherapy in patients with recurrent glioma is susceptible to considerable interobserver variability. This underlines the difficulties that arise in scoring response to chemotherapy by conventional radiologic techniques.

Phase II study of weekly docetaxel and cisplatin in patients with advanced recurrent and metastatic head and neck cancer.

OBJECTIVE: Response rates of presently used palliative chemotherapy for end-stage recurrent head and neck cancer are poor, but the regimes cause important toxicity. METHODS: A prospective phase II study was conducted to evaluate the activity and toxicity of a weekly combination of cisplatin and docetaxel in patients with recurrent head and neck cancer. From July 2003 to November 2004, 21 patients with metastatic neck disease were enrolled. Treatment consistent of 25 mg/m cisplatin and 35 mg/m docetaxel once a week for 3 weeks followed by 1 week without treatment for each cycle. The primary end point was median survival. Secondary end points were response rate (RECIST), time to progression, toxicity (NCI-CTC), and quality-of-life (EORTC QLQ-C30, QLQ-H&N35). RESULTS: Eight patients (42%) showed a partial response. Eight patients (42%) had stable disease. Progressive disease was seen in three patients (16%). The median follow-up time was 7.2 months (95% confidence interval [CI], 5.9-9.3 months). The median time to progression was 3.5 months (95% CI, 2.0-5.0 months). The median overall survival was 10.7 months (95% CI, 6.4-15.0 months). Grade 3 toxicities occurred in two patients (10%). A grade 4 adverse event was not recorded. Most global quality-of-life scores but not head and neck-specific scores are deteriorated after last chemotherapy. CONCLUSION: Weekly docetaxel and cisplatin is active in recurrent head and neck cancer and shows an excellent toxicity profile. Its influence on the stabilization of quality of life is less significant.

[The immunohistochemical growth fraction (Ki-67) of breast cancers: relations to tumor spread, tumor morphology and receptor testing].

245 breast cancer tissues were analysed immunohistochemically, using monoclonal antibody Ki-67, which spezifically reacts with a nuclear antigen of proliferating cells and represents the so-called growth fraction. According to the number of positive cells, three Ki-score categories (I-III) were established. The results were compared with prognostic variables (Histological grading, DNA-cytophotometry), staging parameters, immunocytochemical (ER-ICA, mPRI), and biochemical (DCC) hormone receptor assay. We found a good correlation between Ki-67 and grading (Bloom and Richardson): G 1-tumors had small growth fractions, in contrast to G-III carcinoma, which showed a high percentage of Ki-Score III. Receptor negative cases had a large growth fraction and receptorpositive ones showed an uniform distribution. The comparison between Ki-67 and tumor spread or DNA-Cytophotometry showed no correlation. The majority of 31 recurrent tumors not only had a large number of positive cells, but also a definite dependence was found between Ki-Score and length of the disease-free period. Ki-67 seems to be an important immunohistochemical marker of breast cancer, which contributes to the individual assessment of the disease and can possibly give predictions on tumor development and response to radiation and systemic therapy.

Endoscopic totally extraperitoneal inguinal hernioplasty for recurrence after open repair.

BACKGROUND: Whether endoscopic totally extraperitoneal inguinal hernioplasty (TEP) for recurrent inguinal hernia is as safe and efficacious as that for primary inguinal hernia has rarely been examined. The objective of the present study was to compare the early and late outcomes of TEP for primary and recurrent inguinal hernia. The clinical pattern of recurrence after previous open repair of inguinal hernia was also examined. METHODS: Between August 1999 and November 2003, 100 consecutive patients who underwent TEP for recurrent inguinal hernia were recruited. The outcomes of these patients were compared to a randomly selected control group (n = 100) who had TEP for primary inguinal hernia during the same period. All data had been prospectively collected and analysed. RESULTS: Demographic features were comparable between the two groups. The recurrent group had a significantly higher incidence of direct inguinal hernia than the control group (P < 0.001). Comparison of operative duration, postoperative morbidity, pain score, length of hospital stay and time taken to resume normal activities showed no significant differences between the two groups. However, the incidence of peritoneal tear in the recurrent group (46%) was significantly higher than that of the control group (28%) (P < 0.05). With a mean follow-up of 1 year, the incidences of recurrence and chronic groin pain were similar for both groups. CONCLUSION: Early and late outcomes of TEP for recurrent inguinal hernia were equivalent to those for primary inguinal hernia but a higher incidence of peritoneal tear was encountered during TEP for recurrent inguinal hernia. A predominance of direct hernia was observed in the recurrent group.

Are dysfunctional attitudes in depressive disorder trait or state dependent?

The aim of this study was to investigate whether euthymic patients in remission on lithium prophylaxis score higher on the Dysfunctional Attitude Scale (DAS) than healthy subjects, thus indicating a trait quality of dysfunctional attitudes in unipolar depression. A total of 79 patients with recurrent unipolar depressive episodes and 79 individually matched healthy controls were compared using a Swedish version of the DAS. The results indicate that DAS score is a state-dependent variable in depressive disorder.

Laparoscopic cardiomyotomy for achalasia after failed balloon dilatation.

BACKGROUND: This study was designed to determine the feasibility and outcome of laparoscopic cardiomyotomy in patients with achalasia who have persistent or recurrent dysphagia following balloon dilatation. METHODS: Ten patients who had undergone a minimum of two (range, two to seven) previous balloon dilatations underwent a single anterior cardiomyotomy extending from the gastroesophageal junction onto the esophagus proximally for 6 cm. Four patients had a Toupet fundoplication. Patients were analyzed using pre- and postoperative DeMeester symptom scores for dysphagia, regurgitation, and heartburn (0 = none-3 = maximal) and esophageal manometry. RESULTS: Mean operating time was 90 min. Periesophagitis was noted in some patients but was rarely troublesome. Submucosal fibrosis was present in all patients and made dissection more difficult particularly around the cardioesophageal junction. As a result, three patients had mucosal perforations that required repair by laparoscopic suturing. There were no subsequent postoperative complications. Median (IQR) postoperative stay was 3 (2-4) days. At 3-month reassessment, there was a reduction in the median dysphagia score from 3 to 0, and also in the regurgitation score from 3 to 0. At last follow-up (median, 22 months), one patient had developed recurrent dysphagia (grade 2), which improved with dilatation. Overall success of the laparoscopic procedure was therefore 90%. Only one patient developed new symptoms of reflux (mild, grade 1) after surgery. CONCLUSIONS: Laparoscopic cardiomyotomy provides good control of the symptoms of dysphagia and regurgitation without the morbidity of a laparotomy or thoracotomy incision. Although technically more difficult, the technique can be extended to those who have had previous balloon dilatation with complication and success rates similar to published results in patients who have not undergone previous dilatation.

Surgical treatment of adolescent hallux valgus.

Surgical for adolescent hallux valgus (HV) was performed on 32 feet. Five feet (16%) required revision surgery, and technical errors accounted for recurrence in all five. Satisfaction was obtained in 70% of patients. According to a new bunion rating score, 59% of patients had good to excellent results. In a subgroup of patients treated with metatarsal osteotomy for metatarsus primus varus, the Mitchell osteotomy provided an excellent rating in 95% of patients. Surgery for adolescent HV provides satisfying results in most patients. The one factor most highly correlated with both decreased risk of recurrence of angular deformity and patient satisfaction was a reduction of the intermetatarsal (IM) angle.

Further evidence of a duplication in 17p11.2 in families with recurrence of HMSN Ia (Charcot-Marie-Tooth neuropathy type Ia).

Five Italian families with recurrence of cases of Charcot-Marie-Tooth disease (type Ia) were analysed using three closely linked DNA probes that detect polymorphisms in the region 17p11.2. The probe pVAW409R3 detected the presence of a duplication in all the affected subjects, but not in the subjects with normal electromyographic (EMG) findings. This observation confirms previous data indicating the association of the duplication with the disease, suggesting that, at least in populations of European origin, the duplication might be the molecular feature diagnostic of the pathological trait.

Rheumatic fever recurrence: a possible cause of restenosis after percutaneous mitral valvuloplasty.

BACKGROUND: We evaluated the occurrence of a rapid process of restenosis after percutaneous mitral valvuloplasty (PMV), initiated by the recurrence of acute rheumatic fever. Restenosis after PMV has been mainly related to a high echocardiographic score (> or = 8) indicating a severely compromised mitral valve apparatus. METHODS: From 1986 to 1996, 120 patients underwent PMV by the transseptal approach at our Institution. The mean follow-up time was 58 +/- 32 months (range 3 months to 9 years). RESULTS: Restenosis occurred in 10 patients (8.3%): in 4 restenosis was found within a relatively short period of time (1 to 3 months) following a documented recurrence of acute rheumatic fever; in the other 6 patients there was a gradual loss of the initial gain in the mitral valve area. CONCLUSIONS: These data suggest two potential mechanisms of restenosis: 1) a more common slow process, due to turbulent flow-trauma on the mitral valve; 2) a rapid process that relates to valvulitis consequent to a recurrence of acute rheumatic fever. In consideration of the second possibility, after PMV prophylactic treatment may be warranted at least in those patients who are at high risk of streptococcal infection.

Comparison of efficacy of arthroscopic lavage plus administration of corticosteroids, arthroscopic lavage plus administration of placebo, and joint aspiration plus administration of corticosteroids in arthritis of the knee: A randomized controlled trial.

OBJECTIVE: To compare the efficacy of arthroscopic lavage plus administration of corticosteroids (ALC), arthroscopic lavage plus administration of placebo (ALP), and joint aspiration plus administration of corticosteroids (JAC) in knee arthritis, and to evaluate whether clinical or histologic characteristics determine outcome. METHODS: Patients with knee arthritis (not due to gout, osteoarthritis, or septic arthritis) were randomized over 3 treatment arms: ALC, ALP, and JAC. The primary end point was event-free survival, with events defined as 1) recurrence or persistence of symptomatic knee swelling necessitating local re-treatment, or 2) nonimprovement of the knee joint score. Synovial tissue specimens were collected and analyzed histologically to identify predictive factors of responsiveness. RESULTS: A total of 78 patients were enrolled; 3 patients did not receive their allocated therapy and 3 were lost to followup. The median time until recurrence was 9.6 months after ALC, 3.0 months after JAC, and 1.0 month after ALP, corresponding to a relative risk (RR) of arthritis recurrence of 2.2 for JAC (95% confidence interval [95% CI] 1.2-4.2, P = 0.02) and 4.7 for ALP (95% CI 2.3-9.4, P < 0.0001) compared with ALC. A high versus low synovial extent of fibrosis conferred an RR for recurrence of 5.7 (95% CI 1.6-20.5, P < 0.01) after ALC. CONCLUSION: Arthroscopic lavage plus administration of corticosteroids was more effective than arthroscopic lavage plus administration of placebo or joint aspiration plus injection of corticosteroids. The absence of fibrosis was a histologic predictor of a beneficial response.

Quality of life of patients with recurrent nasopharyngeal carcinoma treated with nasopharyngectomy using the maxillary swing approach.

OBJECTIVE: To investigate factors affecting the quality of life (QOL) of patients with recurrent nasopharyngeal carcinoma who underwent a nasopharyngectomy using the maxillary swing approach. DESIGN: Cross-sectional study using self-administered questionnaire data and medical chart review. SETTING: Tertiary cancer referral center. PATIENTS: Patients with recurrent nasopharyngeal carcinoma who underwent a nasopharyngectomy using the maxillary swing approach between January 1998 and December 2003, had a minimal follow-up of 3 months, and completed the questionnaire. INTERVENTIONS: We measured QOL using the validated traditional Chinese version of the European Organization for Research and Treatment of Cancer core questionnaire and head and neck module. MAIN OUTCOME MEASURES: Descriptive analysis of the results and comparison of scores for each QOL domain, stratified by presence of postoperative trismus, presence of postoperative palatal fistula, sex, age (< or = 45 years and > 45 years), duration of treatment (< or = 1 year and > 1 year), and disease status at follow-up, were performed using nonparametric tests. RESULTS: Of the 50 eligible patients, 41 (32 men and 9 women; mean [SD] age, 51.5 [10.4] years) participated in the study. The mean +/- SD global QOL scale score of the participants was 68.7 +/- 24.2. Social functioning score was the lowest (64.6 +/- 25.9) of the 5 functioning scales. Fatigue and financial difficulties were the most common general concerns. Dryness of mouth, sticky saliva, and limited mouth opening were the most common head and neck problems. Women were found to have significantly lower QOL scores in the fatigue (P = .03), diarrhea (P = .03), and emotional functioning (P = .05) domains than men. The presence of severe trismus after the maxillary swing approach was significantly associated with a low QOL score in the mouth opening (P = .001), sticky saliva (P = .006), mouth dryness (P = .02), and social eating (P = .05) domains. However, the presence of palatal fistula, age, duration of treatment, and disease status at follow-up did not result in any significant differences on the QOL scores. CONCLUSIONS: The QOL of patients treated with nasopharyngectomy using the maxillary swing approach to treat recurrent nasopharyngeal carcinoma was good. Female sex and the presence of postoperative trismus were factors significantly related to some of the QOL domain differences after surgery.

Correlation of total VEGF mRNA and protein expression with histologic type, tumor angiogenesis, patient survival and timing of relapse in non-small-cell lung cancer.

We have quantified the expression of all 4 isoforms of vascular endothelial growth factor (VEGF) mRNA in non-small-cell lung cancer (NSCLC) using a new kinetic quantitative PCR method, real-time quantitative (RTQ) RT-PCR, and investigated the association between VEGF expression at the mRNA and protein levels and the clinicopathologic variables, tumor angiogenesis, patient survival and timing of relapse. Surgical tumor specimens from 72 NCSLC patients (37 squamous-cell carcinomas, 35 adenocarcinomas) were examined. Twenty-eight patients had stage I, 10 stage II and 34 stage IIIA or IIIB disease. Total VEGF mRNA (all 4 isoforms) was quantified by RTQ RT-PCR, while VEGF protein expression and microvessel number in tumors were assessed immunohistochemically. VEGF mRNA was detected in all 72 tumor samples at significantly higher levels than in adjacent normal tissue. Tumoral VEGF mRNA levels correlated strongly with the VEGF protein staining score and microvessel count. Adenocarcinomas showed significantly higher VEGF mRNA expression and a higher protein staining score than squamous-cell carcinomas. High tumoral VEGF mRNA expression was associated with advanced (IIIA or IIIB) tumor stage, lymph node metastasis, high tumoral microvessel counts, short patient survival (<24 months) and early relapse (<12 months), while a high VEGF protein staining score was associated with high tumoral microvessel counts, short patient survival and early relapse. Patients with high tumoral levels of both VEGF mRNA and protein had significantly shorter survival and earlier relapse. In multivariate analysis, the VEGF protein staining score and nodal status were the most important independent predictors of survival and recurrence. We conclude that RTQ RT-PCR is a sensitive method for detecting and quantifying VEGF mRNA expression in NSCLC and that the expression levels of total VEGF mRNA and protein in NSCLC are strongly associated with histologic type, tumor angiogenesis, survival and timing of relapse. High VEGF expression in adenocarcinomas may contribute to their greater metastatic potential.

Investigation of the role of ANKH in ankylosing spondylitis.

OBJECTIVE: The ank/ank mouse develops a phenotype similar to ankylosing spondylitis (AS) in humans. ANKH, the human homolog of the mutated gene in the ank/ank mouse, has been implicated in familial autosomal-dominant chondrocalcinosis and autosomal-dominant craniometaphyseal dysplasia. This study was undertaken to investigate the role of ANKH in susceptibility to and clinical manifestations of AS. METHODS: Sequence variants were identified by genomic sequencing of the 12 ANKH exons and their flanking splice sites in 48 AS patients; variants were then screened in 233 patients and 478 controls. Linkage to the ANKH locus was assessed in 185 affected-sibling-pair families. RESULTS: Five single-nucleotide polymorphisms were identified within the coding region and flanking splice sites. No association between either susceptibility to AS or its clinical manifestations and these novel polymorphisms, or between disease susceptibility and 3 known promoter variants, was seen. No linkage between the ANKH locus and AS was observed. Multipoint exclusion mapping rejected the hypothesis of a locus of a magnitude lambda>/=1.4 (logarithm of odds score <-2) (equivalent to a genetic contribution of >10% to the AS sibling recurrence risk ratio) within this area contributing to AS. CONCLUSION: These findings indicate that ANKH is not significantly involved in susceptibility to or clinical manifestations of AS.

Structural allograft and primary press-fit cup for severe acetabular deficiency. A minimum 6-year follow-up study.

Between October 1992 and December 1996, 23 patients with pelvic bone stock deficiency involving major columns underwent revision surgery with a cementless press-fit cup and a structural bone graft. Twenty cases were followed up for a minimum of 6 (average 7.6, range 6-11) years. Three cups were revised: one for aseptic loosening, one for septic loosening, and one for recurrent dislocation. At latest follow-up, the average Merle d'Aubigne hip score improved from 10.9 to 16.2; four hips were rated excellent, seven very good, three good, two fair, and one poor. All cups were stable; the grafts were integrated and anatomy was restored. The Kaplan-Meier cumulative probability of not having revision for loosening at 11 years, predicted a survival rate of 84.4%. We are confident that these results are satisfactory for a very demanding procedure.
