Is POSSUM predictive of morbidity and mortality in laryngectomy patients?

Objectives

To test the validity of the comparative audit tool of POSSUM (Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity) against a cohort of 92 consecutive laryngectomies at a major tertiary referral centre for head and neck cancer. The major outcome measurements were 30-day mortality rates, formation of a pharyngo-cutaneous fistula, and length of hospital stay.

Methods

By means of a prospective and retrospective case note analysis.

Results

No significant difference between the mean POSSUM morbidity scores of those patients who did, or did not develop a fistula, was found (p = 0.535, 95% C.I. −4.36 to 8.33). No significant correlation was observed between POSSUM predicted morbidity and bed occupancy [r = 0.137 (95% C.I. −0.070 to 0.334)]. The Portsmouth POSSUM equation for mortality however did accurately predict the mortality rate (observed to expected ratio of 1.05).

Conclusion

The authors propose that whilst there are many similar factors linked to mortality between cohorts of general surgical and head and neck patients, there are several highly specific risk factors in open surgery of the upper aero-digestive tract in the head and neck which are linked with wound breakdown and morbidity which are omitted from the POSSUM scoring system. The authors warn against the use of this comparative audit tool in its current state for such surgical procedures and recommend the creation of a specific POSSUM for head and neck cancer surgery.     

Evaluation of smell and taste in patients with Wegener’s granulomatosis

Although a reduced olfactory/gustatory function affects patients in all parts of life, this problem has not received much attention in Wegener’s granulomatosis (WG). The aim of this study was to assess the smell/taste function of WG patients. Demographic data of 16 WG patients (9 males, 7 females) were obtained. They all subjectively assessed their taste/smell function on visual analogue scale. Olfactory/gustatory functions of the patients were tested with ‘Sniffin’ Sticks and ‘Taste’ strips, respectively. The results were then compared with those from sex and age-matched control group (n = 16) and normative data. WG patients subjectively assessed their olfactory (p = 0.03) and gustatory (p = 0.02) function to be lower than control group. All the olfactory scores (odour identification, odour discrimination and threshold) in both genders were significantly below the scores in the control group. WG patients were hyposmic. For taste (total taste score, as well as scores for the qualities sweet, sour, salty and bitter), WG patients did not significantly differ from controls and were normogeusic. However, the gustatory scores showed the tendency of reduction as compared to the control group. In conclusion, WG patients truly suffer from olfactory/taste dysfunction, but this is worse with olfaction. It is, therefore, imperative that physicians should make their patients to be aware of these sensory dysfunctions and educate them on methods to cope with it for better quality of life.     

Reliability assessment and correlation analysis of evaluating orthodontic treatment outcome in Chinese patients

This study aimed to assess the reliability of experienced Chinese orthodontists in evaluating treatment outcome and to determine the correlations between three diagnostic information sources. Sixty-nine experienced Chinese orthodontic specialists each evaluated the outcome of orthodontic treatment of 108 Chinese patients. Three different information sources： study casts （SC）, lateral cephalometric X-ray images （LX） and facial photographs （PH） were generated at the end of treatment for 108 patients selected randomly from six orthodontic treatment centers throughout China. Six different assessments of treatment outcome were made by each orthodontist using data from the three information sources separately and in combination. Each assessment included both ranking and grading for each patient. The rankings of each of the 69 judges for the 108 patients were correlated with the rankings of each of the other judges yielding 13 873 Spearman rs values, ranging from -0.08 to ＋0.85. Of these, 90% were greater than 0.4, showing moderate-to-high consistency among the 69 orthodontists. In the combined evaluations, study casts were the most significant predictive component （R2=0.86, P〈0.000 1）, while the inclusion of lateral cephalometric films and facial photographs also contributed to a more comprehensive assessment （R2=0.96, P〈0.000 1）. Grading scores for SC＋LX and SC＋PH were highly significantly correlated with those for SC＋LX＋PH （r（SC＋LX）vs.（SC＋LX＋PH）=0.96, r（SC＋PH）vs.（SC＋LX＋PH）=0.97）, showing that either SC＋LX or SC＋PH is an excellent substitute for all three combined assessment,     

Cost and morbidity of MRSA in head and neck cancer patients: what are the consequences?

Methicillin resistant Staphylococcus aureus (MRSA) has become a prevalent nosocomial pathogen worldwide. The objectives of this study were to assess the morbidity and cost associated with the treatment of head and neck cancer patients who become colonized or infected with MRSA following major surgical procedures. We present a retrospective review of patients who underwent major surgery for head and neck cancer over a one year period and who then became MRSA positive in the post-operative period. MRSA affected 25/55 (45 per cent) patients who underwent major head and neck procedures during the period studied. The mean time of diagnosis was 13 days post-surgery. Morbidity included cellulitis, osteomyelitis and MRSA pneumonia. Thirteen of the patients who became MRSA positive (52 per cent of the MRSA group) required further surgery including plate removal, new flap formation and wound debridement as a result of the infection. Average in-hospital stay was almost three times more prolonged for patients who became MRSA positive compared to those who did not have MRSA. The costs of the first hospital stay were over three times more in the MRSA-positive group of patients. Antibiotic costs were increased by pound 2470 per patient because of MRSA. The extra stay in hospital, together with extra days in intensive care, extra medical and nursing care and additional costly antibiotic treatment, led to major cost implications and loss of health service resources in the unit. MRSA infection is a serious cause of morbidity in any surgical group of patients and this study focuses on the consequences for treatment of head and neck cancer patients in particular.     

Activities of γ-glutamyl transpeptidase and erythrocyte glutathione dependent enzymes in nasopharyngeal carcinoma patients and normal controls

Summary Plasma -glutamyltranspeptidase (-GT), glutathione peroxidase (GPx) and glutathione reductase (GR) activities were determined in normal and nasopharyngeal carcinoma (NPC) patients. No difference in enzyme activities was observed in the three major races of the Malaysian population, i.e. Malay, Chinese and Indian patients. However, plasma -GT, erythrocyte glutathione S-transferase (GST) and GPx activities were significantly increased in all NPC patients, while GR activity remained unchanged. Patients with elevated plasma -GT activities also had increased GST and GPx activities. Plasma -GT and GPx activities were then found to be affected by treatment. Patients with plasma -GT activity greater than 70 IU/1 had very poor prognoses but patients with decreased -GT activities were found to be in remission.     

Cogan’s syndrome: clinical evolution of deafness and vertigo in three patients

The aim of this study was to evaluate the clinical symptoms, the otoneurological examinations, the treatment and the clinical course of three patients suffering from Cogans syndrome, a rare disease based on the clinical association of a non-syphilitic interstitial keratitis with a cochleo-vestibular deficit. This case series involved three patients with follow up. The clinical course of the three patients (aged 30, 48 and 49 years) with Cogans syndrome during a follow-up period of 2 to 6 years is reported. All patients underwent complete otoneurological, ophthalmologic and rheumatologic examinations and were treated with immunosuppressive therapy such as glucocorticoids and cyclophosphamide in two and glucocorticoids and methotrexate in one patient. Using immunosuppressive therapy, ophthalmologic symptoms disappeared rapidly in two patients. Hearing improved only in one and stabilized in a second patient. One patient died after 6 years of treatment because of complications of generalized vasculitis. Early diagnosis and rapid initiation of a combined immunosuppressive therapy such as corticosteroids and cyclophosphamide seem to be important in controlling the disease and avoiding persistent deafness. Whether systemic complications and a fatal outcome also can be prevented is still questionable.This paper was presented at the 35th Congress of the International Society of Otoneurology, Paris, France, 25 May 2001.     

Erythropoietin in patients with head and neck carcinomas?

BACKGROUND: Various studies have demonstrated the prognostic significance of the pretherapeutic blood hemoglobin concentration for patients with head and neck cancer following surgery or primary definitive or adjuvant radio- or radiochemotherapy. It was the aim of this study to evaluate whether the prognosis of these patients might be improved when correcting decreased pretherapeutic hemoglobin values by administering erythropoietin. METHOD: In a prospective placebo-controlled double-blind study (Cochrane "evidence-based medicine" level Ib) the effect of erythropoietin was analyzed in patients with locally advanced head or neck tumours with low blood hemoglobin values (women: < 12 g/dL; men: < 13 dL) and a Karnofski value of > 60 following primary definite or adjuvant radiotherapy (up to 70 Gy). The time to local tumour progression and survival was evaluated. Kaplan-Maier estimates were applied and, the relative risk of well-known prognostic factors tested for with a Cox Proportional Hazards model. RESULTS: 157 patients of the Freiburg University ENT-clinic were recruited from 1997 to 2001. Study conduct was performed according to the GCP guidelines. A rapid increase of the blood hemoglobin value happened during the first five weeks of treatment under epoetin beta. Placebo patients experienced only minor changes of the hemoglobin value. Following adjuvant radiotherapy local tumour control probability at two years was 68 % +/- 7 % and 72 +/- 7 % for placebo and epoetin beta patients, respectively (p = 0.64). Patients who had undergone primary definite radiation experienced a local control probability of 36 % +/- 11 % in the placebo arm after two years, compared to epoetin beta with 23 % +/- 11 % (p = 0.05). CONCLUSION: Epoetin beta resulted in prompt and stable correction of blood hemoglobin values in anemic patients with advanced head or neck tumours, but tumour control and survival was impaired particularly in patients with a high tumour burden.

Is type 1 tympanoplasty effective in elderly patients? Comparison of fascia and perichondrium grafts

Abstract

Background: Tympanoplasty is regularly performed in various ages but data about the procedure in elderly is insufficient.

Objectives: To compare the success rates and hearing outcomes of fascia and perichondrium grafts used for tympanoplasty in patients >65 years and to evaluate the prognostic factors affecting the success of tympanoplasty.

Methods: Reviewing records of 49 elderly patients underwent tympanoplasty, two groups were constituted: perichondrium (25 patients) and fascia (24 patients) groups. Ages, genders, perforation sides, type and location of perforation, graft success rates, functional success rates and air–bone gap (ABG) gains were compared.

Results: Overall graft success rate was 85.7%. After a mean follow-up of 23.3?±?8.32 months, overall mean ABG gain was 11.33?±?8.42?dB. Overall median postoperative ABG value (9?dB) was significantly lower compared to the median preoperative value (24?dB) (p?<?.001). Graft success rate was higher in perichondrium group (96%) compared to fascia group (75%) (p?=?.04). Functional success rate did not significantly differ between perichondrium (68%) and fascia groups (62.5%) (p?=?.68).

Conclusion and significance: Tympanoplasty is an effective procedure with a graft success rate of 85.7% in elderly. Both fascia and perichondrium are suitable materials; however, perichondrium had higher success rate.

Evaluation of the predictive role of neutrophil/lymphocyte ratio in the diagnosis of lymphoma in patients with asymptomatic and ısolated cervical lymphadenopathy

IntroductionThe diagnostic approach to patients with isolated asymptomatic cervical lymphadenopathy varies between excisional biopsy and follow-up. When the anamnesis, physical examination, laboratory and imaging findings are not sufficient to identify the etiology, an excisional biopsy is performed for the differential diagnosis between early-stage lymphoma and infectious or reactive causes. If the excisional biopsy, which may have some complications, is not performed, it may delay the diagnosis of lymphoma. This diagnostic challenge could be avoided by predictive markers.ObjectivesThis study was planned to determine the predictive value of neutrophil/lymphocyte ratio in the diagnosis of Hodgkin and non-Hodgkin limphoma in patients with asymptomatic, isolated cervical limphadenopathy and underwent excisional biopsy.MethodsA total of 90 patients between the years 2016 ? 2019 admitted to our clinics due to asymptomatic isolated cervical lymphadenopathy, present in at least 4 weeks with lympho nodes in pathological dimensions persisting in the cervical region, were included to our study. An excisional lympho node biopsy was performed in all 90 patients.ResultsOf the 90 patients who underwent excisional biopsy; 34 were diagnosed as reactive lymphadenopathy 30 were non-Hodgkin linphoma, and 26 were Hodgkin linphoma. A total of 56 (62.2%) patients were diagnosed as lymphoma, either Hodgkin or non-Hodgkin, while 34 patients (38.8%) were diagnosed as reactive lymphadenopathy. The median age, total whiteblood count, neutrophil count of the lymphoma groups were significantly higher than reactive lymphadenopathy group, whereas the lymphocyte count was significantly lower in the lymphoma patients. The median neutrophil/ lymphocyte ratio was 1.7 in the reactive lymphadenopathy group, 3.5 in the non-Hodgkin limphoma group, and 3.0 in the Hodgkin limphoma group (p <  0.001).ConclusionAccording to the results of our study, neutrophil/lymphocyte ratio was significantly higher in patients who were admitted with isolated asymptomatic lymphadenopathy and were diagnosed with lymphoma, and who were diagnosed with early-stage Hodgkin and non- Hodgkin lymphoma compared to those who were found to have reactive lymphadenopathy. Neutrophil/lymphocyte ratio, which is a low-cost, fast and easy-to-access test, has a predictive value in the diagnosis of lymphoma in patients with asymptomatic lymphadenopathy.     

Does quality of life predict long-term survival in patients with head and neck cancer?

OBJECTIVE: To assess whether pretreatment and posttreatment quality of life (QOL) is associated with long-term survival in patients with head and neck cancer. DESIGN: Ten-year follow-up of an inception cohort. SETTING: Regional tertiary referral center. PATIENTS: The study included 200 consecutive patients with primary epithelial head and neck cancer. INTERVENTIONS: Quality of life and several recognized risk factors for death were assessed prospectively using the Auckland QOL questionnaire before treatment and 12 months after treatment; survival was determined at 10 years. MAIN OUTCOME MEASURES: Survival and odds of death (hazards ratio) were measured. RESULTS: At 10 years, 136 patients (68%) were deceased, 48 patients (24%) were alive, and the status of 16 patients (8%) was unknown. Median survival was 6 years (interquartile range, 4.4-7.7). Before treatment, patients with low QOL had no significantly increased odds of death (hazard ratio, 1.4; 95% confidence interval, 0.8-2.4). In contrast, after treatment, patients with low QOL at 1 year had significantly increased odds of death (2.5; 95% confidence interval, 1.4-4.3; P = .001) even after adjustment for covariates. CONCLUSIONS: Findings suggest potential survival benefits from improvements in QOL. However, the observed associations between survival benefit and QOL at 1 year may be confounded by comorbidity, which was not measured and deserves further investigation.     

Quality of life and patients’ satisfaction after otoplasty

The objective of the study was to present the long-term results of satisfaction and quality of life of patients after otoplasty due to protuberant ears. A retrospective study at an academic tertiary referral centre is presented. A total of 164 patients were followed up after otoplasty due to ear dysplasia grade I. The validated questionnaires SF-36 and Patient Outcomes of Surgery-head/neck (POS) were applied to evaluate the quality of life and the patients’ satisfaction after therapy. The comparison of preoperative and postoperative quality of life measured by POS showed significantly higher scores after surgery than before, independent of gender, age or experience of the surgeon. The patients’ satisfaction with the surgical outcome showed high values in all subgroups. Except for “vitality”, the SF-36 showed for all other items higher values of postoperative quality of life for patients after otoplasty than the German control population. With this study, we were able to demonstrate that health-related quality of life of patients is significantly increased by otoplasty. This finding is most pronounced in early childhood (children younger than 10?years of age), but independent of gender, experience of the surgeon or whether a revision or a primary case was treated. The method of performing otoplasty as described in this paper has been used in our institution for many years. It is adapted to the specific pathology and combines resection with suture techniques. To confirm and complement our results and increase the knowledge in this field of surgery, a prospective study is not only needed but currently performed.     

prevalence of the gjb2 mutations in deafness patients of different ethnic origins in xinjiang

Objective To investigate GJB2 mutation prevalences in the Uigur and Han ethnic groups in Xinjiang, China, and determine the relationship between ethnicity and GJB2 gene mutations. Methods Information regarding ethnicity of patients' families was obtained through medical records review and/or patient interview. Blood samples were collected from 61 Uigurs and 66 Hans for direct sequencing of the coding region and intron/exon boundaries of the GBJ2 gene. Results Carrier frequency of GJB2 mutations was similar between the Uigur and Han subjects. The GJB2 35delG mutation was seen only in Uigur patients with hearing loss, whereas the 235delC mutation was identified in both Uigur and Han patients. The allelic Frequency of 35delG mutation was 7.4% (9/122) in Uigur deaf students, but none in Han deaf students (0/128) and Uigur controls (0/196). The allelic frequency of GJB2 235delC mutation in Uigur and Han deaf students was 5.7% and 9.8%, and that of 299-300delAT mutation was 0.8% and 5.5%, respectively. V27I and E114G were the most frequent types of polymorphism. Conclusion We found an Asian-specific GJB2 diversity among Uigurs, and comparable GJB2 contribution to deafness in Uigur and Han patients. The high carrier frequency of 35delG in Uigurs (11.5%) is probably defined by gene drift/founder effect in a particular group. Even though GJB2 mutations have been widely reported in the literature, this discussion represents the first report of GJB2 mutations in Chinese multi-ethnic populations.     

The causes of the development of cicatrical stenosis of the larynx and trachea in the patients presenting with Guillain-Barré syndrome

The problem of rehabilitation of the patients presenting with post-intubation stenosis of the larynx and trachea remains unresolved despite the development of new methods for the diagnostics and treatment of this condition. One of the indications for long-term artificial lung ventilation is the severe form of Guillaine-Barret syndrome associated with paralysis of breathing muscles, development of bulbar symptoms, and disturbances of trophic process in the skin and mucous membranes. However, prolonged (mean 26 days) artificial lung ventilation may result in the formation of many-layer stenosis of the larynx and trachea whereas disturbed trophic processes in the skin and mucous membranes coupled to inadequate innervation complicate the postoperative conditions of the patients and promote restenosis of the tracheal lumen.     

Epidemiologic analysis of patients with laryngeal and hypopharyngeal cancer treated in the Department of Otolaryngology in Białystok from 1986-1999

Epidemiological analysis of patients with the larynx cancer, who were treated in the Department of Otolaryngology in Bia?ystok from 1996 to 1999 was performed. The following aspects were assessed: a) number of patients, b) gender, c) age, d) place of living, e) primary site of the tumour. The results in years 1996-1999 were compared with the earlier published results in years 1986-1994. Altogether 1431 patients (1340-93.6% males and 91-6.4% females) in that period and there were similar numbers of hospitalizations every year. Among patients there were 28-33% farmers, 41-46% labourers, 5-9% white collar workers, the others were old age pensioners. 55-59% patients came from the rural areas and 41-45% patients from urban areas. The most common site of the primary tumour was the supraglottic region (831-58.1%), then glottis (421-29.4%) and rarely in the subglottic region (5-0.3%). Hypopharynx was the tumor primary site in 174 (12.2%) patients. The analysis showed that the numbers of patients with cancer of the larynx or hypopharynx are similar in each year. A constant increase in number of female patients; coming from the rural area, farmers or labourers was found. Increasing incidence rate of supraglottic tumours and little decrease in the number of glottic tumours were also found.     

relative contributions of spectral and temporal cues for speech recognition in patients with sensorineural hearing loss

The present study was designed to examine speech recognition in patients with sensorineural hearing loss when the temporal and spectral information in the speech signals were co-varied. Four subjects with mild to moderate sensorineural hearing loss were recruited to participate in consonant and vowel recognition tests that used speech stimuli processed through a noise-excited voeoder. The number of channels was varied between 2 and 32, which defined spectral information. The lowpass cutoff frequency of the temporal envelope extractor was varied from 1 to 512 Hz, which defined temporal information. Results indicate that performance of subjects with sensorineural heating loss varied tremendously among the subjects. For consonant recognition, patterns of relative contributions of spectral and temporal information were similar to those in normal-hearing subjects. The utility of temporal envelope information appeared to be normal in the hearing-impaired listeners. For vowel recognition, which depended predominately on spectral information, the performance plateau was achieved with numbers of channels as high as 16-24, much higher than expected, given that the frequency selectivity in patients with sensorineural hearing loss might be compromised. In order to understand the mechanisms on how hearing-impaired listeners utilize spectral and temporal cues for speech recognition, future studies that involve a large sample of patients with sensorineural hearing loss will be necessary to elucidate the relationship between frequency selectivity as well as central processing capability and speech recognition performance using vocoded signals.     

Does septoplasty enhance the quality of life in patients?

Evaluation of the severity of disease and the effectiveness of operative treatment is commonly done by registering pre- and postoperative symptoms. During the preceding decade, greater awareness has focused not only on the symptoms but also on patients’ quality of life (QoL). The aim of the study was to determine the effect of septoplasty, as measured by generic and disease-specific QoL questionnaires. The generic 15D and disease-specific SNOT-22 questionnaires were given to patients before the operation and 6?months after the operation. Data analysis consisted originally of 188 septoplasty patients. One-hundred and twenty-six patients (67%) answered the SNOT-22 questions, and in the 15D, the response rate was 76%. In the post-operative SNOT-22, the need to blow the nose, sneezing, runny nose, nasal obstruction, loss of smell or taste, post-nasal discharge, facial pain/pressure, difficulty in falling asleep and waking up at night improved significantly. However in the 15D the mean QoL, i.e., general well-being, became significantly poorer. The QoL became increasingly poor especially in the older age groups and among the patients in which the improvement achieved in nasal symptoms postoperatively was minor. The more nasal symptoms the patients had pre- or postoperatively, the poorer the QoL was in general. Based on our results, critical evaluation of the symptoms and findings in the patients is essential in deciding whether surgery or other treatment should be given to individual patients having nasal blockage symptoms. Especially in patients with mild symptoms or among older patients, adequate medical treatment has to be tried before even considering surgery. The results also encourage the use of a systematic questionnaire to estimate the severity of symptoms in daily clinical practice.
