Opioid switching and variability in response in pain cancer patients.

INTRODUCTION: Opioid switching is a possible strategy for inadequate analgesia or unmanageable side effects. Its effectiveness ranges from 50 to 90% and is still debated. PURPOSE: We analyzed the impact of opioid switching in a cancer pain population treated with strong opioids for pain. METHODS: This is a post hoc analysis from a multicenter, randomized, four-arm, controlled, phase IV clinical trial. Outcome variables included the percentages of switches, the reasons for the switch, the dose changes before and after the switch, depending on the starting opioid, the response in case of inadequate analgesia, and unmanageable toxicity, and the variability of response among and within patients. RESULTS: We analyzed 498 patients. The opioid was switched in 79 patients (15.9%) 87 times, mainly for uncontrolled pain (52.3%), adverse opioid reactions (22.1%), both of these (4.8%), and dysphagia (20.8%). The reasons for switching varied depending on the starting opioid. Pain reduction was good after 51.45% of switches and control of opioid side effects was good after 43.5%. The relief of opioid-induced toxicity varied among adverse events and within each patient. The daily doses were higher after switching oral opioids and lower after transdermal drugs. CONCLUSIONS: Half of the patients who underwent switching experienced improved relief of pain or amelioration of opioid toxicity. The switch can help in the management of some cases but with many limits and uncertainties.

Electroporation Enhances Bleomycin Efficacy in Cats with Periocular Carcinoma and Advanced Squamous Cell Carcinoma of the Head.

BACKGROUND: Advanced carcinoma of the head represents a substantial health problem in cats for local control and overall survival. OBJECTIVES: Evaluate the capability of electrochemotherapy (ECT) to improve bleomycin efficacy in cats with periocular carcinoma and advanced carcinoma of the head. ANIMALS: Twenty-one cats with periocular carcinoma (17 squamous cell carcinoma [SCC] and 4 anaplastic carcinoma) and 26 cats with advanced SCC of the head. METHODS: Nonrandomized prospective controlled study. Periocular carcinoma cohorts: 12 cats were treated with bleomycin (15 mg/m(2) i.v.) coupled with ECT under anesthesia; 9 cats were treated with bleomycin alone. Advanced head SCC cohorts: 14 cats were treated with bleomycin (15 mg/m(2) i.v.) coupled with ECT administered under sedation; 12 control cats were treated with bleomycin alone. ECT treatments (2-8) were performed every other week until complete remission (CR) or tumor progression occurred. RESULTS: Toxicities were minimal and mostly treated symptomatically. Overall response rate in the ECT treated animals was 89% (21 Complete Response [CR] and 2 Partial Response [PR]) whereas controls had response rate of 33% (4 CR and 3 PR). Median time to progression in ECT group was 30.5 months, whereas in controls it was 3.9 months (P < .0001). Median time to progression for ECT cohorts was 24.2 months for periocular cohort and 20.6 in advanced head SCC cohort, respectively. CONCLUSIONS: Electrochemotherapy is well tolerated for advanced SCC of the head in cats; its use may be considered among loco-regional strategies for cancer therapy in sensitive body regions such as periocular region.

Illness awareness in terminal cancer patients: an Italian study.

The amount and quality of information and awareness in cancer patients' is a topic frequently debated, but few studies have focussed on terminal patients. This is the objective of the present study that involved two different palliative home-care units in Italy, which recruited 550 terminal cancer patients. Data from patients and their caregivers was prospectively collected with special attention to information patients were provided with when their cancer was diagnosed and patients' awareness of their current health condition. In the case of the information, 67.0% of patients reported they were previously informed about their diagnosis, but only 58.0% seemed to be aware of their terminal condition. The comparison between the caregivers opinions about the level of information provided to the patients and their present awareness and what the patients really know about their own disease shows a high degree of correspondence. Some variables such as age and education level of patients were associated with patient's awareness.

Correlation of findings at direct laryngoscopy and bronchoscopy with gastroesophageal reflux disease in children: a prospective study.

OBJECTIVE: To correlate direct laryngoscopic and bronchoscopic findings with the presence of positive test results for gastroesophageal reflux disease (GERD) in children. DESIGN: Prospective collection of structured data. SETTING: An academic pediatric otolaryngology department. PATIENTS: Seventy-seven consecutive patients who underwent direct laryngoscopy and bronchoscopy between June and October 1999. INTERVENTIONS: During direct laryngoscopy and bronchoscopy, descriptions of 7 laryngeal and 6 cricotracheal findings were recorded on a 3-point scale (i.e., absent, mild, or severe). Medical records were later reviewed to obtain results of the following tests, if they were part of the record: gastric scintiscan, 24-hour pH probe monitoring, upper gastrointestinal tract series, and esophageal biopsy. MAIN OUTCOME MEASURES: Correlation of mucosal abnormalities with the presence or absence of a positive test result for GERD. RESULTS: Fifty (65%) of 77 patients had GERD diagnosed with at least 1 positive test result, 21 (27%) had no clinical symptoms and no positive GERD test results, and 5 (7%) had clinical symptoms but no positive test results. There were significant differences for total laryngeal and cricotracheal scores (P<.001) between the groups with positive and negative results. Significant differences were as follows: in the larynx-large lingual tonsil (P<.001), postglottic edema (P<.001), arytenoid edema (P<.001), ventricle obliteration (P =.03), and true vocal fold edema (P = .001), and in the cricotracheal region-general edema and erythema (P =.003) and blunting of the carina (P<.001). Severe arytenoid edema, postglottic edema, or enlargement of lingual tonsil were pathognomonic of GERD. CONCLUSION: Many direct laryngoscopic and bronchoscopic findings correlate well with the diagnosis of GERD as determined by using other tests.

Effectiveness of adenoidectomy and laser tympanic membrane fenestration.

OBJECTIVE: Adenoidectomy alone or with tonsillectomy (A+/-T) is an effective surgical intervention in the management of otitis media in children, especially when it is performed in conjunction with insertion of pressure equalization tubes (PETs). Otorrhea and persistent tympanic membrane (TM) perforation are frequent complications. This study evaluates the effectiveness of intermediate duration middle ear ventilation using laser tympanic membrane fenestration (LTMF) without tube insertion and as an adjunct to adenoidectomy in resolving middle ear disease within the first 90 days after surgery. STUDY DESIGN: This pilot study was a multicenter, prospective clinical cohort trial. Institutional review board approval and informed consent were obtained. The study involved four tertiary care pediatric otolaryngology departments. Fifty children (96 ears) were treated with LTMF in conjunction with A+/-T from June 1, 1998, through March 30, 1999. Ages ranged from 9 months to 12 years. Patients undergoing A+/-T who would have been recommended for PET insertion instead underwent middle ear ventilation with LTMF using the Oto-LAM device (ESC/Sharplan, Yokneam, Israel). Patients were seen at 30, 60, and 90 days postoperatively. Resolution of otitis media with effusion was determined by clinical examination, which included pneumatic otoscopy, audiometry, and tympanometry. RESULTS: Of the treated ears, 88%, 86%, and 83% had clinical resolution of middle ear disease at 30, 60, and 90 days, respectively. Preoperatively, 45% (n = 85) of ears had normal hearing; 92% (n = 49) had normal hearing at 90 days. Eighty-nine percent (n = 92) had type C2 or B tympanograms preoperatively, and 12% (n = 60) had type C2 or B at 90 days. CONCLUSION: Laser tympanic membrane fenestration in conjunction with adenoidectomy was effective in restoring normal middle ear function at 90 days post-treatment in greater than 80% of children who otherwise may have had placement of PETs.

Success rates in paediatric tympanoplasty.

OBJECTIVE: To determine if the success of paediatric tympanoplasty is dependent on certain criteria, which are determinable prior to surgery. DESIGN: Retrospective chart review. SETTING: An academic paediatric otolaryngology department. PATIENTS: Seventy-seven patients who had undergone tympanoplasty with or without ossicular reconstruction, but without mastoidectomy, between April 1997 and May 1999. MAIN OUTCOME MEASURES: Status of the repaired tympanic membrane at last follow-up visit measured by otoscopic examination and with tympanometry. RESULTS: Eighty-nine tympanoplasties were performed during this period. The age range was 2.9 to 22 years. The success rate was 75% overall. For patients younger than 11 years (n = 43), the success rate was 82%, and for those 11 to 18 years (n = 44), it was 74%, which was not significantly different. In 18 patients 7.5 years or younger, the success rate was 79%. Perforation location, size, presence of myringosclerosis, status of the other ear or nose, history of the perforation, surgical approach, middle ear findings, canal packing, and gender were not shown to be significantly different between successful and unsuccessful tympanoplasty groups. CONCLUSION: These young patients had a good success rate post-tympanoplasty, which we believe reflects less severe disease. These results mitigate against delaying tympanoplasty in young children.

Correlation of findings on direct laryngoscopy and bronchoscopy with presence of extraesophageal reflux disease.

OBJECTIVE: To determine the correlation between findings at direct laryngoscopy and bronchoscopy and presence of extraesophageal reflux disease (EERD). STUDY DESIGN: Retrospective chart review METHODS: Operative notes of 155 children undergoing direct laryngoscopy and bronchoscopy between 1996 and 1999 for airway symptoms for whom there was a suspicion of EERD were examined. Gastroesophageal reflux disease (GERD) was considered present if at least one test was positive (including upper GI series, pH probe, gastric scintiscan, or esophageal biopsy). RESULTS: A total of 130 (84%) patients had GERD diagnosed. Ninety percent had at least one laryngotracheal abnormality: 83% had an abnormal larynx and 66% had an abnormal trachea. Laryngeal abnormalities in GERD included postglottic edema, 69%; arytenoid edema, 30%; large lingual tonsil, 16%; vocal fold edema, 12%; vocal fold nodule, 12%; ventricular obliteration, 5%; and hypopharyngeal cobblestoning, 3%. Tracheobronchial abnormalities in GERD included tracheal cobblestoning, 33%; blunting of carina, 12.5%; subglottic stenosis, 11%; increased secretions, 11%; and generalized edema or erythema, 5%. The best sensitivity or specificity was obtained by combining postglottic edema, arytenoid edema, and vocal fold edema, resulting in a sensitivity of 75% and a specificity of 67%. Positive predictive value was 100% for the combination of postglottic edema and any vocal fold or ventricular abnormality. CONCLUSION: Laryngoscopy and bronchoscopy can reveal findings with a high positive predictive value for the presence of GERD. Endoscopy of the upper airway in children with clinical signs and symptoms of EERD is a promising tool for diagnosis.

Clinical presentation as a guide to the identification of GERD in children.

OBJECTIVE: to determine if there is a correlation between common otolaryngologic symptoms and presence of gastroesophageal reflux disease (GERD) in children. METHODS: charts of 295 children presenting with suspicion of GERD were reviewed for presenting symptoms including: (1) airway symptoms: stertor, stridor, frequent cough, recurrent croup, wheezing, nasal congestion, obstructive apnea, blue spells, hoarseness, throat clearing; (2) feeding symptoms: wet burps, globus sensation, frequent emesis, dysphagia, choking/gagging, sore throat, halitosis, food refusal, stomach aches, arching, drooling, chest pain, irritability, and failure to thrive. At least one positive test of barium esophagram, gastric scintiscan, pH probe or esophageal biopsy resulted in inclusion in the GERD positive group. RESULTS: 214 children had GERD diagnosed while 81 had no positive tests for GERD. Between the GERD positive and GERD negative groups, the significantly different symptoms were stertor (P=0.040), cyanotic spells (P=0.043), frequent emesis (P=0.007), failure to thrive (P=0.006), and choking/gagging (P=0.044). Three pooled variables were created: airway flow (stertor, stridor, cyanotic spells), airway irritation (frequent cough, recurrent croup, throat clearing), and feeding (dysphagia, failure to thrive, frequent emesis). GERD patients who were 2 years or less were compared to those older than 2 years and all three of these pooled variables were significantly different between these groups (P<0. 001). CONCLUSION: children who present with a certain constellation of airway or feeding symptoms are more likely to have a positive GERD test. Children 2 years old or less are more likely to present with airway symptoms or feeding difficulties while children older than 2 years are more likely to present with airway irritation.

Lymphangiosarcoma of the pubic region: a rare complication arising in congenital non-hereditary lymphedema.

Lymphangiosarcoma is a rare, aggressive, vascular neoplasm arising in chronic congenital or acquired lymphedema. Although it is most frequently associated with post-mastectomy lymphedema (Stewart-Treves's syndrome), lymphangiosarcoma can exceptionally arise in congenital hereditary lymphedema (Milroy's syndrome and Meige's syndrome) and non-hereditary lymphedema (congenital, praecox or forme tarde lymphedemas). We report a case of lymphangiosarcoma of the pubic region, supported by immunohistochemical studies, in a 42-year-old woman affected by congenital, non-hereditary lymphedema of the left genital region and homolateral lower limb. In addition, molecular analysis demonstrated the absence of Kaposi's sarcoma-associated Herpes virus (KSHV) DNA sequences in tumour lesions. To our knowledge, this is the first case of lymphangiosarcoma associated with congenital non-hereditary lymphedema confined to the pubic region. The literature concerning the cases of lymphangiosarcoma arising in congenital hereditary and non-hereditary lymphedema is reviewed. Moreover, we emphasized the importance of regular clinical controls in all patients affected by chronic lymphedema. In fact, although the prognosis of this neoplasm is very poor, a prompt diagnosis and a rapid, ablative surgery associated with radiation therapy can increase the possibility of survival of these patients.

Common topics in pediatric otolaryngology.

This article outlines the perioperative and long-term management of children undergoing tonsillectomy, adenoidectomy, tympanostomy with tube insertion, and sinus surgery. Indications for complications of each of the procedures is reviewed in this article. The authors also cover the management of children with tracheostomies. Several questions frequently asked by parents of children with a tracheostomy are addressed.

Supernumerary nostril: a rare congenital deformity.

Duplication anomalies of the nose include polyhinia (double nose) and supernumerary nostril (assessory nostril). These are rare congenital nasal deformities resulting from aberrant embryological development. Differential diagnoses include glioma, encephalocele, nasal dermoid, nasolacrimal duct duplication, mid facial cleft and proboscis lateralis (K. Nakamura, T. Onizuka. Plast. Reconstr. Surg. 80 (3) (1987) 436-441). Our review of the English language literature revealed eight reported cases of duplication anomalies of the nose. Four of these were cases of polyrhinia (double nose). Of the cases remaining, one patient had a supernumerary nostril in association with a cleft lip, leaving only three reported cases of an isolated supernumerary nostril. We present a newborn infant with an isolated right supernumerary nostril. MRI, CT and photographic documentation are provided. Pertinent embryology, anatomy and a thorough review of the literature are included.

Aplasia of the epiglottis: a rare congenital anomaly.

Aplasia of the epiglottis is a rare laryngeal anomaly. We present a case of absence of the epiglottis in a child whose clinical course has been followed for nine years. She required a tracheostomy at two years of age for obstructive sleep apnea which resulted in heart failure; she was eventually decannulated at age seven. This case report highlights the clinical challenges faced in the identification and treatment of the sequelae of this defect. Both endoscopic and computed tomography (CT) documentation are provided. Embryological development and a review of the literature are also discussed.

Deep neck infections in children: a new approach to diagnosis and treatment.

Forty-seven children presented with the diagnosis of a deep neck infection--either cellulitis or abscess--between January 1991 and July 1996. Forty-four (94%) had contrast-enhanced computed tomography (CT) imaging consistent with this diagnosis. Three patients with no CT scan had confirmation of an abscess at surgical drainage. Parenteral antibiotics alone were effective in the treatment of 24 of 47 infections (51%): seven parapharyngeal, one retropharyngeal, and 16 combined. By CT scan these infections represented cellulitis in 17 of 24 (71%), an abscess in three of 24 (13%), and incomplete abscess in four of 24 (17%). The average duration of hospitalization for this group was 4.8 days, with symptomatic improvement usually seen within 24 hours. Surgical drainage was performed on 23 of 47 infections (49%): three parapharyngeal, 17 combined, and three of unknown specific location. In 22 of these 23 children (96%), transoral drainage of the abscess was used as the primary surgical approach. In 21 of these 22 (95%) there was complete resolution without complications or recurrence; one abscess required a subsequent external approach. CT scanning with contrast revealed that all deep neck infections were located medial (usually anteromedial) to the great vessels. Abscesses with volumes estimated to be greater than 2000 mm3 were more likely to undergo surgery, but these differences were not statistically significant. The use of contrast-enhanced CT scanning provides information regarding abscess size, location, and relative position of the great vessels for safe and successful transoral drainage. Thus we recommend CT-assisted transoral drainage for combined retropharyngeal/parapharyngeal abscesses and selected isolated parapharyngeal abscesses that do not respond to parenteral antibiotics.

Risk of Kaposi's sarcoma-associated herpes virus transmission from donor allografts among Italian posttransplant Kaposi's sarcoma patients.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a newly discovered herpes virus found in all forms of Kaposi's sarcoma (KS) including KS among immunosuppressed transplant patients. It is unknown whether this virus is transmitted by organ transplantation or is reactivated during immunosuppression among those patients infected before transplantation. To investigate the risk of KSHV transmission during organ transplantation, we conducted a case-control study of transplant recipients with and without KS matched to their respective donors. Sera were collected at time of transplantation and tested in a randomized and blinded fashion using four KSHV serologic assays testing for antibodies to both latent and lytic phase antigens. Ten (91%) of 11 organ recipients who developed KS were seropositive prior to transplantation by one or more of the assays compared with two (12%) of 17 control organ recipients (OR = 75, 95% CI = 4.7, 3500). KS cases were more likely to have been born in southern Italy where KS is endemic than the recipient controls or either donor group. Only four (36%) of 11 donors to case patients and three (18%) of 17 donors to control patients were seropositive (P = .38, two-tailed Fisher's exact test). KSHV transmission could not be ruled out for the single KS patient seronegative at transplantation and clear evidence for organ-related transmission was found for another KS patient outside of the case-control study. Antibodies to KSHV are detectable in the sera from most transplant recipients before initiation of immunosuppressive treatment suggesting that KS among immunosuppressed transplant patients is primarily due to virus reactivation. KSHV transmission, however, from an infected allograft can occur, and our study reports the first documented case of person-to-person transmission of KSHV.

Open trial of intravenous immune serum globulin for chronic sinusitis in children.

BACKGROUND: Chronic sinusitis in children is a complex clinical problem. Some patients do not improve with medical therapy and some fail surgery as well. OBJECTIVE: A therapeutic trial of intravenous immune serum globulin (IVIG) was given to children whose sinus disease was recalcitrant to the usual therapeutic modalities. The objective of IVIG administration was to modulate the inflammatory process contributing to the chronicity of the sinusitis. METHODS: Six patients were given a 12-month trial of monthly (400 mg/kg) IVIG infusions. Entry criteria included persistence of sinusitis after 3 months of full course antibiotics, or two episodes of sinusitis within a 3-month period while on prophylactic antibiotics. All patients had abnormal sinus CT (computerized tomography) scans at entry. Three of the six patients remained symptomatic despite prior sinus surgery. Patients with primary immune deficiencies were excluded. Each patient served as his own control based on their previous 12-month history and clinical course. Four of the 6 patients were atopic as demonstrated by prick skin testing; however, all patients had nasal eosinophilia. RESULTS: Full course antibiotic use decreased in five of the six patients (183 to 84 days); correspondingly, the episodes of sinusitis decreased (average 9 to 4 per year). In addition, sinus CT scans showed significant improvement. CONCLUSION: This preliminary open-trial of IVIG suggests its usefulness as adjunct therapy to medical management in selected patients with chronic sinus disease. The mechanism(s) by which IVIG may be helpful is probably not based on the concept of replacement therapy, but more likely as an immune or inflammatory modulating agent.

Simultaneous onset of primary cutaneous B-cell lymphoma and human herpesvirus 8-associated Kaposi's sarcoma.

We report the simultaneous occurrence of Kaposi's sarcoma (KS) and primary cutaneous B-cell lymphoma (CBCL) of the leg in a 79-year-old woman, seronegative for HIV-1, HTLV-1 and HTLV-2. The CBCL underwent complete clinical remission after local radiotherapy, whilst the KS became disseminated within a year following diagnosis. However, 2 years after the diagnosis of KS, the patient died with neurological symptoms. These were presumed to be due to involvement of the central nervous system by lymphoma, although in the absence of an autopsy, this could not be proven. Skin biopsies from the original KS and CBCL lesions, as well as short-term culture of spindle cells from the KS lesion and peripheral blood mononuclear cells (PBMC), were studied by semiquantitative polymerase chain reaction (PCR) using primers specific for DNA sequences of a novel gamma-herpesvirus-8 (HHV-8). PCR studies were strongly positive for the virus on KS cells and PBMC; conversely, a low viral load was found on CBCL cells. A high titre of serum IgG antibodies reacting with the nuclei of the HHV-8 positive cell line BCP-1 was found. These data suggest that reactivation of latent infection with HHV-8 had occurred in this patient, and that HHV-8 is directly involved in KS, but not in CBCL of the leg, an aggressive variant of CBCL.

Clinical classification as a guide to treatment of sinusitis in children.

Evaluation of all 153 children undergoing CT scan of the paranasal sinuses for recalcitrant sinusitis symptoms between January 1988 and July 1992 was performed. Clinical categorization into groups of patients presenting with chronic sinusitis (CS) and recurrent acute sinusitis (RAS) was based upon pattern of disease and presentation. Clinical symptoms and signs, radiological examination, treatment, and outcome were compared between these distinct clinical groups. Eighty-two (55%) children were categorized as RAS and 68 (45%) as CS. Children with CS presented more frequently with a persistent cough, purulent nasal discharge, immune deficiency, and more severe mucosal disease on CT than children with RAS. Medical therapy successfully controlled the symptoms of sinusitis in 79 (96%) with RAS versus 27 (40%) with CS. Surgery was performed in 44 children: 3 (3.6%) with RAS versus 41 (60%) with CS, p < 0.01. At a mean follow-up of 2.0 years, >80% of all the children were either asymptomatic or improved regardless of treatment modality. These data support the use of clinical classification as a guide to medical versus surgical therapy in children with sinusitis.

Neonatal septoplasty: case report and review of the literature.

Treatment of nasal septal deformity in childhood has received growing acceptance in recent years. Traditionally, concern about the role of the septum in the overall growth of the midface has led otolaryngologists to take a very cautious approach to correction of septal deformities in children. However, a great deal of evidence now suggests that severe traumatic septal deviation can and should be corrected early in childhood to prevent future nasal and systemic complications. Closed manipulation of the septum in the first 1-2 days of an infant's life has been performed by many otolaryngologists with good results. The use of this technique, however, is usually limited to those subluxations of anterior cartilage which are diagnosed immediately or very shortly after birth. We present a case of severe traumatic nasal deformity presenting with obstructive asleep and awake apnea and cyanosis at the age of 8 days. The child underwent limited septoplasty using endoscopic techniques at age 14 days with resolution of both the apneic and cyanotic episodes immediately post-operatively. This unusual presentation and the literature surrounding infant nasal/septal surgery are discussed.
