Percutaneous tracheotomy in bone marrow transplant patients with severe thrombocytopenia.

OBJECTIVE: Evaluation of percutaneous tracheotomy in bone marrow transplant patients with severe thrombocytopenia. DESIGN: A retrospective outcome study. PATIENTS: A retrospective study of 26 percutaneous tracheotomies was performed at the Bone Marrow Transplant Unit, Rambam Medical Center, Haifa, Israel. Age, sex, underlying disease, reason for intubation, complete blood count, coagulation profile, and the incidence of renal failure were collected. All patients received 6 units of platelets one hour prior to the procedure. RESULTS: The mean platelets count was 14,300 +/- 5500. Twenty-five of the 26 percutaneous tracheotomies were completed successfully, without any intraoperative complications. One patient suffered from moderate bleeding during the procedure, which was immediately stopped and converted to open tracheotomy. In the postoperative period 4 patients suffered from mild bleeding around the stoma, which was managed conservatively. No other late complications were encountered. CONCLUSIONS: Percutaneous tracheotomy can be safely performed in patients with severe thrombocytopenia when the surgeon and anesthesiologist are experienced in the procedure, and platelets are given perioperatively.

Magnesium: a new therapy for idiopathic sudden sensorineural hearing loss.

OBJECTIVE: To determine whether treatment with Mg(2+) improves the outcome of idiopathic sudden hearing loss and to investigate which variables influence its prognosis. STUDY DESIGN: Prospective randomized study. SETTING: Department of Otolaryngology-Head and Neck Surgery, Rambam Medical Center, Haifa, Israel. PATIENTS: The study group included 133 patients. Sixty patients were treated with carbogen inhalation, and 73 were treated with a combination of carbogen inhalation and intravenous MgSO(4). RESULTS: The mean improvement rate was 66.4% in the Mg(2+) group and 49.9% in the carbogen group (p < 0.01). Recovery was achieved in 35 patients (48%) in the Mg(2+) group and only in 19 patients (31.6%) in the carbogen group (p < 0.01). Significant improvement was seen in 20 patients (27.4%) in the Mg(2+) group and in 14 patients (23.3%) in the carbogen group. Partial improvement was seen in eight patients (10.9%) in the Mg(2+) group and in 12 patients (20%) in the carbogen group. No improvement was achieved in 10 patients (13.6%) in the Mg(2+) group and in 15 patients (25%) in the carbogen group. Patients with vestibular symptoms had a poorer hearing outcome compared to those without vertigo (p < 0.04). Patients who commenced the treatment 8 days or more after onset had poorer recovery as compared with those who started treatment earlier (p < 0.03), regardless of the treatment regimen. Age, sex, and tinnitus had no significant impact on hearing recovery. CONCLUSION: We found that Mg(2+) improved hearing recovery in cases of idiopathic sudden hearing loss. Vertigo and treatment delay beyond 8 days were poor prognostic factors for recovery.

Percutaneous dilation tracheotomy versus surgical tracheotomy: our experience.

BACKGROUND: Percutaneous dilation tracheotomy (PDT) is becoming a popular alternative to surgical tracheotomy. In our department, we recently adopted the use of the PDT in intensive care unit patients. Here, we compare the results of the use of these 2 techniques on 150 patients, all performed by the same surgeon. We discuss the pros and cons of PDT and present our experience with the technique compared with surgical tracheotomy (ST). MATERIALS AND METHODS: A prospective study of 75 PDTs and a retrospective study of 75 surgical tracheotomies (ST) were performed at the Department of Otolaryngology-Head and Neck Surgery, Rambam Medical Center, Haifa, Israel. Age, sex, duration of intubation before surgery, time interval between the decision to perform and the performance of tracheotomy, and cost were compared. RESULTS: One hundred fifty tracheotomies were reviewed. The indication for tracheotomy in both groups was prolonged mechanical ventilation. Seven patients were found unsuitable for PDT and underwent ST. Complications included 3 cases of mild postoperative hemorrhage in the ST group, and 1 case of subcutaneous emphysema, 1 case of stomal cellulitis and 2 cases of mild postoperative hemorrhage in the PDT group. The average waiting interval was between 2 to 5 days for ST and 1 to 24 hours for PDT. The intraoperative time for ST was 20 minutes; for PDT, 5 minutes. The cost was 565 dollars for ST and 274 dollars for PDT. CONCLUSIONS: PTD provides an easy, less expensive, and convenient alternative to ST and should be added to the otolaryngologists' armamentarium of surgical airway procedures. The procedure is advantageous for the patient. Complication rates of both techniques are similar and low; however, PDT is a blind technique of obtaining a surgical airway and therefore holds more potential for serious complications. It is our conclusion that this technique is suitable for many, but not all, critical care patients and that the procedure should be performed only by surgeons who are capable of urgently obtaining a surgical airway or exploring the neck should the PDT fail.

Delayed diagnosis of tracheoesophageal prosthesis aspiration.

In 1980, Singer and Blom published the results of their study on use of the tracheoesophageal puncture prosthesis for restoration of voice after total laryngectomy. Since then, the placement of tracheoesophageal puncture prostheses has been an integral part of rehabilitation after laryngectomy. Complications of this procedure have been recognized and are usually minimal. Inadvertent aspiration of the prosthesis is rare. Usually, patients seek help immediately after the incident. We report a case of unnoticed aspiration of a Blom-Singer prosthesis in a patient with a laryngectomy.

The use of otic powder in the treatment of acute external otitis.

BACKGROUND: Acute external otitis (AEO) is a painful condition that results as a secondary infection of macerated skin and subcutaneous tissues of the external auditory canal. The most commonly causative microorganisms are Pseudomonas aeruginosa and Staphylococcus aureus. Classic management strategies include moisture prevention, cleansing of the canal and administration of topical antimicrobial agents in drop form, such as aminoglycosides and quinolones, at times in combination with steroid solutions. The objective of this study was to evaluate and compare the efficacy of topical otic powder, tobramycin drops and ciprofloxacin drops in patients suffering from AEO. MATERIALS AND MEASURES: A randomized prospective trial was performed to determine the efficacy of Auricularum powder (dexamethasone 10 mg, oxytetracycline HCl 90,000 U, polymyxin B Sulfate 100,000 U, nystatin 1,000,000 U; Trima, Serolam Laboratories, Germany) compared with ciprofloxacin (Ciloxan, Alcon Laboratories, Fort Worth, TX) and tobramycin (Tobrex, Alcon Laboratories) drops for the treatment of AEO. One hundred twenty patients who presented with signs and symptoms of AEO were enrolled. Inclusion criteria were: AEO diagnosed by an otolaryngologist, patient age 18 years, no prior treatment with other drops or systemic antibiotics, no sensitivity to any of the drugs used or their contents, and no perforation of the tympanic membrane. All patients were instructed to avoid moisture and wetness of the ear during the course of their treatment. After we received informed consent, a swab culture was taken, and the patient was randomly assigned topical treatment for 14 days. RESULTS: Eighty-six percent of those treated with Auricularum powder were cured at day 3-4 after initial treatment. Seventy-seven percent of those treated with ciprofloxacin drops, and fifty-six percent of those treated with tobramycin were cured at that time. All 120 patients were cured by day 14. CONCLUSION: The results show that topical treatment with Auricularum powder is an effective and rapid method for the treatment of AEO. Ciloxan also was effective in the treatment of AEO and relieved symptoms quickly and efficiently in a short period of time. Tobrex was effective in treating AEO, but our results show that relief of symptoms was slower than with the other drugs.

Tracheotomy: changing indications and a review of 1,130 cases.

BACKGROUND: Tracheotomy is one of the oldest known operations, dating back to ancient Egypt and India some 3000 years ago. The indications for tracheotomy have changed and expanded during the twentieth century. Today, owing to advancements in intensive care and the widespread use of mechanical ventilation, tracheotomy is one of the most commonly performed surgical procedures and is encountered on a regular basis by hospital physicians in all fields. We present one of the largest series of consecutive tracheotomies spanning one decade. We review and discuss the modern indications for tracheotomy and emphasize the changes in these indications over the past century. METHODS: A retrospective study of 1,130 consecutive tracheotomies performed over one decade is presented. We studied the indications for surgery, the complications and mortality rate, and the various hospital departments requiring tracheotomies. RESULTS: A total of 1,130 tracheotomies were performed: 859 to assist in mechanical ventilation, 124 as an adjunct to head and neck or chest surgery, and 68 to relieve upper airway obstruction. Major complications occurred in 49 of the cases, and there were 8 deaths directly attributed to the tracheotomies. The most common complication was tracheal stenosis, occurring in 21 cases. Hemorrhage was the second most common complication, occurring in 9 cases. CONCLUSION: Tracheotomy, once used almost exclusively to bypass upper airway obstruction, is now a very common elective therapeutic procedure used mostly to facilitate prolonged intubation and ventilation of the critically ill. Today tracheotomy is not and should not be an emergency procedure owing to the huge complication and mortality rate of emergency tracheotomy and the existence of alternative routes to obtain immediate airway control in the acutely obstructed upper airway.

The beverage maté: a risk factor for cancer of the head and neck.

BACKGROUND: Maté is a tealike beverage consumed habitually in South America and among South Americans throughout the world. It is brewed from the dried leaves and stemlets of the perennial tree Ilex paraguariensis (yerba maté), a species that belongs to the Aquifoliaceae family. Maté consumption has been associated with an increased rate of oral, oropharyngeal, esophageal, and laryngeal cancers. The purpose of this study is to review the literature and discuss the role of Maté consumption as a risk factor for head and neck cancers. MATERIALS AND METHODS: We performed a thorough review of the relevant literature linking maté consumption with head and neck cancer and the proposed carcinogenicity of maté. Case control studies on maté-drinking populations and in vivo and in vitro studies on the carcinogenicity of maté were reviewed. The populations included in many of these studies also used alcohol and tobacco products, confounding the influence of maté as an independent risk factor. RESULTS: Evidence in the literature suggests that maté consumption is carcinogenic and plays a role in the development of cancers of the oral cavity, pharynx, larynx, and esophagus. CONCLUSIONS: The exact mechanism of carcinogenesis of maté is unknown. Both chemical and thermal carcinogenesis mechanisms have been suggested. Available information suggests that maté drinking is a risk factor for upper aerodigestive tract cancer.
