Tracheostomy during SARS-CoV-2 pandemic: Recommendations from the New York Head and Neck Society

The rapid spread of SARS‐CoV‐2 in 2019 and 2020 has resulted in a worldwide pandemic characterized by severe pulmonary inflammation, effusions, and rapid respiratory compromise. The result of this pandemic is a large and increasing number of patients requiring endotracheal intubation and prolonged ventilator support. The rapid rise in endotracheal intubations coupled with prolonged ventilation requirements will certainly lead to an increase in tracheostomy procedures in the coming weeks and months. Performing tracheostomy in the setting of active SARS‐CoV‐2, when necessary, poses a unique situation, with unique risks and benefits for both the patient and the health care providers. The New York Head and Neck Society has collaborated on this document to provide guidance on the performance of tracheostomies during the SARS‐CoV‐2 pandemic.

Metastatic medullary carcinoma of thyroid presenting as a dural-based mass: case report and review of literature

Dural metastasis from medullary thyroid carcinoma (MTC) is not well established in English literature. We present the case report of MTC with unusual clinical presentation as a dural-based mass in a 39-year-old male with no family history of multiple endocrine neoplasia syndrome. Magnetic resonance imaging showed an extra-axial dural-based mass in right frontal lobe with calvarium and soft tissue extension to the right superior orbit. Histopathology showed MTC with variegated morphology and various patterns. Thyroid mass and widespread metastases from medullary thyroid carcinoma were subsequently identified.

Randomized trial of influenza vaccine with granulocyte-macrophage colony-stimulating factor or placebo in cancer patients

PURPOSE

To determine whether granulocyte-macrophage colony-stimulating factor (GM-CSF) would improve response to influenza vaccination in cancer patients.

PATIENTS AND METHODS

In a randomized, patient-blinded, placebo-controlled trial carried out in 1997 to 2000, 133 patients were stratified into five groups of treatment and disease. Single doses of standard split trivalent influenza vaccine and either placebo or 250 micro g of GM-CSF were administered at the same time. Hemagglutination inhibition assay titers were measured before and 4 weeks after vaccination.

RESULTS

Standard analyses, which define response as at least a four-fold increase in titers, detect no effect of GM-CSF for any of the three influenza subtypes in the trivalent vaccines (P >or=.12). Analysis that includes the magnitude of the change in titers and combines responses of the subtypes suggests that the placebo group had the greater response (P =.051), thus indicating that GM-CSF does not improve response. Ancillary analyses show that response declines both with increasing age and with higher initial titers. The fraction of patients with at least a four-fold increase in titers was 0.36 (95% confidence interval, 0.29 to 0.42)

CONCLUSION

A single 250- micro g dose of GM-CSF administered with the influenza vaccine does not improve response to vaccination. Response in cancer patients is low and declines as age and initial titer increase.

A phase I study of recombinant human interleukin-2 and alpha-interferon-2a in patients with renal cell cancer, colorectal cancer, and malignant melanoma

Preclinical data suggest synergy of interleukin-2 (IL-2) combined with alpha-interferon (IFN). In addition, toxicities of IL-2 may be decreased by intermittent continuous infusion. The purpose of this trial was to determine the maximum tolerated dose (MTD) of recombinant IL-2 combined with alpha-IFN in patients with renal cancer, colon cancer, melanoma, and malignant B-cell disease. IL-2 was given by continuous i.v. infusion at an initial dose of 5 X 10(5) units (U)/m2/d for 4 days plus IFN at 6 X 10(6) U/m2/d intramuscularly days 1 and 4 weekly for 4 weeks. Patients who achieved a response or stable disease received an additional 4 weeks of therapy. IL-2 doses were increased to 1, 2, 3, 5, and 7 X 10(6) U/m2/d with three to eight patients at each dose level, at each of the two participating institutions. The dose of IFN was 6 X 10(6) U/m2 days 1 and 4 for all but five patients whose IFN dose was doubled to 12 X 10(6) U/m2/d. Forty-three patients were entered on this study with 34 completing at least 4 weeks of therapy. Six patients were taken off study because of Grades III or IV pulmonary, neurologic, or cardiac toxicity; one for progressive disease; one for CNS metastases, and one for personal reasons. All of the toxicities were reversible. Chills and fever were universal, especially on days 1 and 4. Mild and moderate nausea, vomiting, diarrhea, anorexia, malaise, and cutaneous erythema were present in most patients. Fluid retention and occasional pleural effusions were observed at the higher IL-2 doses but were not dose-limiting. Significant hypotension associated with oliguria was seen, and these patients were treated with vasopressors and colloids. None of the patients required ICU admission. Thirty-four patients were evaluable for response. There were 4/18 (22%) renal cell patients who experienced a partial response. No responses were seen in patients with melanoma, lymphoma, or colorectal cancer. The combined debilitating symptoms of fatigue, diarrhea, hypotension, fluid retention, and anorexia defined the MTD as 5 X 10(6) U/m2/d of IL-2 and 6 X 10(6) U/m2 of alpha-IFN.

Phase II trial of fludarabine phosphate (F-Ara-AMP) in patients with advanced head and neck cancer

Thirteen patients with advanced head and neck cancer were entered into a phase II study of fludarabine phosphate. Fludarabine phosphate was given by continuous infusion for 5 days, at a starting dose of 20 mg/m2 per day for patients previously treated with one regimen and 25 mg/m2 per day for previously untreated patients; therapy was repeated every 3-4 weeks. Of the 13 patients, 3 had undergone one prior regimen and 10 patients were previously untreated by chemotherapy. No responses were observed. Myelosuppression was the most common toxicity observed. Four patients developed mild nausea, vomiting and seven developed bleeding stomatitis that resolved in one week. In addition, four patients developed headaches which resolved spontaneously. No renal, hepatic, or neurotoxicity was observed. Our study demonstrates that in previously treated and untreated patients, fludarabine phosphate given on this schedule has little activity in patients with advanced head and neck cancer.

Lack of protection against bacterial infections in patients with advanced cancer treated by biologic response modifiers

A survey of patients with advanced cancer treated by biologic response modifiers (BRMs), including (i) recombinant interleukin-2 and lymphokine-activated killer cells, (ii) recombinant interleukin-2 and alpha interferon, and (iii) tumor necrosis factor, was done. A total of 52 patients were reviewed. A total of 73 courses of BRMs were administered. Prior to the initiation of therapy, all patients were infection free and not receiving antibiotics. Twelve patients developed bacteremia during treatment with these BRMs. Five of these 12 patients had catheter-related bacteremia. Six patients had bacteremic infections without an obvious source, and one patient had a urinary tract infection with bacteremia. Staphylococcus epidermidis accounted for six of the isolates. Other organisms were Staphylococcus aureus, group B streptococci, viridans group streptococci, and gram-negative bacilli. This was an unexpectedly high incidence of bacterial infections in patients treated with BRMs. These BRMs have been previously shown to be efficacious against infections (by bacteria and other intracellular organisms) in experimental animals. In this study BRMs did not influence host defense mechanisms or offer protection against bacterial infections.

Treatment of patients with advanced cancer using multiple long-term cultured lymphokine-activated killer (LAK) cell infusions and recombinant human interleukin-2

Escalating doses of recombinant human interleukin-2 (rIL-2) were combined with long-term cultured rIL-2 activated killer cells to treat patients with disseminated melanoma, renal cell cancer, and colon cancer. Twenty-four patients were entered, 12 with renal cell cancer, 8 with colon cancer, and 4 with melanoma; 23 were evaluable for efficacy and toxicity. The (dose-related) toxicities were moderate to severe and consisted of fever, chills, rigors, weight gain, hypotension, mild confusion, elevation of liver enzymes and serum creatinine, thrombocytopenia, and eosinophilia. No cardiac events (arrhythmias or myocardial infarction) were recorded. None of the patients were admitted to the intensive care unit, and no deaths occurred. Two partial responses were observed, one at relatively low doses of rIL-2 in a patient with renal cell carcinoma and one at the highest dose level in a patient with malignant melanoma. The maximally tolerated dose level of rIL-2 for this study was 6 X 10(6) U/m2 i.v./day. The recommended dose for further studies is 3 X 10(6) U/m2 i.v./day in three divided doses.

Amsacrine with high-dose cytarabine is highly effective therapy for refractory and relapsed acute lymphoblastic leukemia in adults

Thirty-six patients with relapsed acute lymphoblastic leukemia (ALL) and four with primary refractory ALL were treated with a regimen that included amsacrine, 200 mg/m2, intravenously daily for three days with cytarabine, 3 gm/m2, by infusion over three hours daily for five days. There were 27 remissions in the 36 relapsed patients and two in the four patients with primary refractory disease. Seventeen of the 23 patients with common ALL, four of the six with T-cell ALL, one of the three with B-cell ALL, and seven of eight whose cells were not characterized responded. Toxicity of this regimen was comparable to other reinduction regimens for ALL, but the side effects characteristic of high-dose cytarabine therapy were absent. Since these results compare favorably with conventional induction regimens, its use in the primary treatment of adults and children with high-risk ALL is proposed.

Phase II trial of fludarabine phosphate (F-Ara-AMP) in patients with advanced breast cancer

Eighteen patients with advanced breast cancer were entered into a phase II study of fludarabine phosphate. Fludarabine phosphate was given by continuous infusion for 5 days, at a starting dose of 20 mg/m2 per day for patients previously treated with two or more regimens and 25 mg/m2 per day for minimally treated patients with less than two prior regimens; therapy was repeated every 3-4 weeks. Of the 18 patients, 11 had undergone more than two prior regimens and 7 patients had undergone one prior regimen. One patient achieved a partial response (PR) for 22 months. Myelosuppression was the most common toxicity observed. Four patients developed mild nausea and vomiting and two developed a nonspecific dermatitis that resolved spontaneously. No renal, hepato-, or neurotoxicity was observed. Our study demonstrates that in heavily pretreated patients, fludarabine phosphate given on this schedule has minimal efficacy in treating advanced breast cancer. This drug might possibly have shown more activity in a previously nontreated patient population. However, patients with advanced breast cancer, who have not undergone previous treatment are not often encountered.

Thrombocytopenic purpura in narcotics addicts

Since November 1982 we have seen an association of thrombocytopenic purpura with chronic narcotic addiction in 70 patients with a mean platelet count of 53000 +/- 4000 (SE); 33 had stopped taking intravenous drugs for an average of 21.2 +/- 4.7 months; 13 of 15 had elevated antibody titers for a virus related to the acquired immunodeficiency syndrome. Platelet-bound IgG, IgM, and complement levels were 16.7-, 5.6-, and 3.1-fold greater than control values, respectively, and 2.6-, 1.9-, and 2.4-fold greater than values in 25 patients with classic autoimmune thrombocytopenic purpura studied at the same time. Thirty-three of thirty-six addicts had elevated circulating immune complexes, whereas 8 patients with autoimmune thrombocytopenia had no elevation. Eleven of eighteen addicts had positive serum platelet-reactive IgG titers, compared to 5 of 19 patients with classic autoimmune thrombocytopenia. The platelet-reactive IgG in sera of addicts was composed of 7S IgG antibody as well as high molecular weight (immune complex) IgG. Thus, chronic addicts appear to have a new immunologic platelet disorder associated with the presence of 7S IgG antiplatelet antibody, like patients with classic autoimmune thrombocytopenic purpura, and immune complex associated nonspecific platelet IgG, like male homosexual patients with thrombocytopenia.
