Abstract
In unstructured interviews, 24 Mexicans described survivors' responses to disasters in Guadalajara, Jalisco (n = 9), Homestead, Florida (n = 6), and Puerto Angel, Oaxaca (n = 9). This analysis assessed the extent to which symptom descriptions corresponded to the 17 criterion symptoms of PTSD. Nineteen participants (79%) mentioned from 1 to 9 criterion symptoms. Event-related distress, hypervigilance, recurrent recollections, and avoiding reminders were described most often. Only 3 criterion symptoms were never described. Twenty participants (83%) provided 109 separate expressions that could not be classified specifically as criterion symptoms. These phrases were sorted by 9 independent Mexican volunteers and cluster analyzed. Clusters composed of ataques de nervios, depression, lasting trauma, and somatic complaints provided the best description of the data.

Abstract
BACKGROUND Some patients fail to acquire tracheoesophageal (TE) speech after laryngectomy because of pharyngeal constrictor hypertonicity. Botox injection relieves hypertonicity, but there are little objective data regarding outcomes, duration of effect, and reinjection rates. METHODS Hypertonicity was identified by means of insufflation testing and confirmed videofluoroscopically in 23 unsuccessful TE speakers. Each patient received an EMG-guided Botox injection. Additional injections were offered if the first injection failed to produce fluent speech. RESULTS Overall, 20 of 23 patients (87%) achieved fluent TE speech production after Botox injections; 5 after additional injections. Two patients declined further intervention, and 1 failed to achieve fluent TE speech production even after 3 Botox injections. The longest sustained effect was 37 months, the shortest was 5 months for 1 patient who required reinjection of Botox to maintain her TE speech production. CONCLUSIONS Botox injection relieves constrictor hypertonicity in selected cases of TE speech failure with little need for reinjection to maintain long-term speech success.

Abstract
The purpose of this study was to review the incidence, risks, management, and outcomes of nontumoral laryngeal stenosis after supracricoid partial laryngectomy (SCPL) in a case series of 376 consecutive SCPLs performed at 1 institution from 1975 to 1995 with a minimum of 3 years of follow-up. Post-SCPL nontumoral symptomatic laryngeal stenosis was defined as an inability to decannulate patients before the 60th postoperative day (group 1) or the development of dyspnea (in patients without local recurrence) after an initial period of prolonged, successful decannulation (group 2). Of 376 SCPLs performed, nontumoral symptomatic laryngeal stenosis developed in 14 (3.7%). There were 7 patients (1.85%) in group 1 and 7 patients (1.85%) in group 2. In univariate analysis, none of the following variables appeared to be statistically related to the risk of immediate stenosis (group 1): age, gender, comorbidity, diabetes mellitus, symptomatic gastroesophageal reflux, arteritis, preoperative radiotherapy, arytenoid cartilage disarticulation, type of reconstruction performed, and postoperative radiotherapy. A delayed laryngeal stenosis (group 2) was statistically more likely to occur if the reconstruction performed at the time of SCPL was a cricohyoidopexy (p = .01). Successful management of the laryngeal stenosis without permanent tracheostomy was achieved in 5 group 1 patients and 3 group 2 patients. We believe that stenosis in group I patients arose through technical error, whereas group 2 patients seemed to suffer from problems of healing, mainly cicatricial narrowing of the airway at the site of the cricohyoidal impaction, or pexis. As a result, whereas laryngeal stenosis in group 1 patients was usually more easily correctable through dilation, laser incision, or resection of redundant tissue or revision of the impaction, laryngeal stenosis in group 2 patients presented a more difficult and frustrating complication. The management and outcomes of these patients are presented.

Abstract
Skull base osteomyelitis (SBO) is typically bacterial in origin and caused by Pseudomonas, although the fungus Aspergillus has also rarely been implicated. SBO generally arises from ear infections and infrequently complicates sinonasal infection. Rhinocerebral Mucor infection is characteristically an acute, fulminant, and deadly infection also affecting the orbits and deep face and is associated with intracranial complications. Bony involvement is uncommon because of the angioinvasive nature of the fungus. More recently, chronic invasive Mucor sinusitis has been described. We report the unusual clinical and imaging features of a patient with biopsy-proven invasive mucormycosis arising from chronic isolated sphenoid sinus disease, who presented with extensive SBO and a paucity of deep facial, orbital, or intracranial involvement.

Abstract
BACKGROUND The current conservative standard of care for T2 squamous cell carcinoma of the glottis is either partial laryngectomy or radiation therapy. METHODS Based on an inception cohort of 100 patients with T2 squamous cell carcinoma of the glottis and a minimum of 3 years of follow-up, the present study documented the results achieved with a multimodal strategy using platinum-based induction chemotherapy and partial laryngeal surgery. Statistical analysis of survival and local control was based on the Kaplan-Meier actuarial life table method. Univariate analysis was performed to determine whether there was a correlation among various factors and toxicity, clinical response, histologic regression, local control, and survival. RESULTS A complete clinical response and a partial response after induction chemotherapy was achieved in 24% and 58% of patients, respectively. Complete histologic regression was noted in 31%. A significant statistical relation (P < 0.0001) was noted between a complete clinical response after induction chemotherapy and a complete histologic regression. The 5-year actuarial survival estimate was 85.8%. The 5-year actuarial local control estimate was 95.7% (97.7% if the vocal cord was mobile and 93.8% if the motion of the vocal cord was impaired). Salvage treatment resulted in an overall 99% rate of local control and a 95% rate of laryngeal preservation. CONCLUSIONS Because this represents a nonrandomized retrospective study, no definitive conclusions can be derived. However, when compared with the data reported in a large series using radiation therapy or partial laryngectomy alone, this 10-year experience suggests that, in patients with "early" invasive squamous cell carcinoma of the glottis, the use of platinum-based induction chemotherapy prior to a conventional conservative treatment modality should be investigated further.

Abstract
OBJECTIVE To evaluate the effectiveness of the posterolateral neck dissection in providing regional control of metastatic disease to the posterior triangle from head and neck primary tumors as part of a multidisciplinary treatment approach. DESIGN A case series review of 55 patients treated over a 10-year period form 1982 through 1991 with a minimum of 3 years of follow-up. Factors evaluated included site and histologic type of primary tumors, extent of surgery performed, other therapies provided, pathologic findings, and clinical outcome. SETTING The University of Texas M.D. Anderson Cancer Center, Houston. PATIENTS Forty-six male and nine female patients were studied. Three of them had bilateral dissections, for a total of 58 operations. Thirty-five were diagnosed as having melanoma; 10, squamous cell carcinoma, and 10, various other histologic types. INTERVENTION All patients underwent a posterolateral neck dissection, either alone or as part of a multidisciplinary treatment plan. OUTCOME MEASURES Factors reviewed were recurrence, either at the primary site or at a regional site, development of distant metastases, and surgical morbidity. RESULTS Our review showed that, overall, disease was controlled at the site of the primary tumor in 89% of patients (94% of patients with melanoma) and that regional disease was controlled in 93% of patients (89% of patients with melanoma). Surgical morbidity was minimal. CONCLUSION The "functional" posterolateral neck dissection as practiced at the University of Texas M.D. Anderson Cancer Center is effective surgical therapy that provides control of regional metastatic disease to the posterior neck from head and neck primary tumors.

Abstract
The developmental potential of embryonic stem (ES) cells versus 3.5 day inner cell mass (ICM) was compared after aggregation with normal diploid embryos and with developmentally compromised tetraploid embryos. ES cells were capable of colonizing somatic tissues in diploid aggregation chimeras but less efficiently than ICMs of the same genotype. When ICM in equilibrium with tetraploid and ES in equilibrium with tetraploid chimeras were made, the newborns were almost all completely ICM- or ES-derived, as judged by GPI isozyme analysis, but tetraploid cells were found in the yolk sac endoderm and trophectoderm lineage. Investigation of ES contribution in 13.5 day ES in equilibrium with tetraploid chimeras by DNA in situ hybridization confirmed the complete tetraploid origin of the placenta (except the fetal blood and blood vessels) and the yolk sac endoderm. However, the yolk sac mesoderm, amnion and fetus contained only ES-derived cells. ES-derived newborns failed to survive after birth, although they had normal birthweight and anatomically they appeared normal. This phenomenon remains unexplained at the moment. The present results prove that ES cells are able to support complete fetal development, resulting in ES-derived newborns, and suggest a useful route for studying the development of genetically manipulated ES cells in all fetal lineages.

Abstract
Tracheal agenesis (TA) is a rare congenital anomaly that is incompatible with prolonged life. It occurs in isolation or in association with other anomalies. The affected neonate presents with respiratory distress and is unable to produce an audible cry despite obvious physical effort. A difficult intubation ensues, and often only during a postmortem examination is the diagnosis of TA made. It is hoped that in addition to adding the 47th case of TA to the literature, this article will provide some insight into the pathogenesis, presentation, and management of this anomaly. It must be emphasized that as TA carries a fatal prognosis, great care must be taken in establishing the diagnosis. If the diagnosis is confirmed, complex reconstructive surgery is not recommended as it has not been shown to change the prognosis or clinical course of affected neonates.
