RESUMO

Objective: To investigate the therapeutic effect and prognostic value of oligoclonal bands (OB) in multiple myeloma (MM) patients after autologous stem cell transplant (ASCT). Methods: The data of 156 patients with MM who underwent ASCT after inductive treatment in the Department of Hematology, Jiangsu Provincial People's Hospital from December 2013 to February 2022 were retrospectively analyzed, including 91 males and 65 females. The median age was 56 (26, 71) years. Patients were divided into two groups according to OB formation after ASCT treatment, including OB group (n=60) and non-OB group (n=96). The last follow-up date was August 31, 2023, and the follow-up period was 42 (18, 117) months. The clinical baseline characteristics and efficacy of the two groups were compared. Progression-free survival (PFS) and overall survival (OS) were compared between the two groups by Kaplan-Meier method. Cox risk regression modal was used to analyze the risk factors associated with prognosis. Results: There were no significant differences in age, type, stage, risk stratification, extramedullary disease (EMD), proportion of circulating plasma cells and induction therapy regimen between OB and non-OB groups (all P>0.05). The proportion of patients in OB group who achieved complete response (CR) or above after ASCT treatment was 93.3% (56/60), which was higher than that in non-OB group (80.2%, 77/96) (P=0.024). The negative rate of minimal residual disease (MRD) in OB group was 66.7% (40/60), which was higher than that in non-OB group (34.4%, 33/96) (P=0.001). The median PFS and OS in the OB group were not reached, and the median PFS and OS in the non-OB group were 28 (2, 80) months and 86 (2, 100) months, respectively. The PFS (P<0.001) and OS (P=0.017) of patients with OB were considerably longer. In the Cox multivariate analysis, OB was an independent prognostic factor for PFS in MM patients (HR=0.314, 95%CI: 0.153-0.644, P=0.002). Subgroup analysis showed that among high-risk patients with mSMART, the OS of patients in OB group was not reached, which was significantly better than that of non-OB group [71 (2, 90) months, P=0.046]. However, no significant difference was observed in the OS of patients with OB and those with non-OB in standard risk group (not reached vs not reached, P=0.103). In those with EMD at diagnosis, patients with OB had significantly better OS than those with non-OB [not reached vs 47 (6, 74) months, P=0.037]. However, no significant difference was observed in the OS of patients with OB and those with non-OB in those without EMD at diagnosis [not reached vs 86 (2, 100) months, P=0.130]. Conclusions: OB formation after ASCT treatment in MM patients is related to the efficacy and prognosis. OB formation can increase the negative MRD rate, prolong the OS and improve the prognosis, especially for newly diagnosed patients with extramedullary disease or patients with high-risk genetic characteristics.

RESUMO

Objective: To investigate the clinical effect of focused ultrasound ablation surgery (FUAS) combined with suction curettage for mass-type cesarean scar pregnancy (CSP) and to analyze the influencing factors of vaginal bleeding and readmission. Methods: From January 2014 to December 2020, 88 patients with mass-type CSP were treated by FUAS combined with suction curettage in the Third Xiangya Hospital of Central South University. The clinical results and the influencing factors of bleeding and readmission for mass-type CSP were analyzed. Results: All the patients underwent one time FUAS treatment successfully. Immediately after FUAS treatment, color Doppler ultrasound showed obvious necrosis and no perfusion area in all lesions, and the blood flow in the mass-type CSP tissue significantly decreased. The median volume of blood loss in the procedure was 20 ml (range: 5-950 ml). Thirteen patients (15%, 13/88) had vaginal bleeding≥200 ml, and 15 patients (17%, 15/88) were hospitalized again. The average time for menstruation recovery was (28±8) days (range: 18-66 days). The average time needed for serum human chorionic gonadotropin-beta subunit to return to normal levels was (22±6) days (range: 7-59 days). The risk of large vaginal bleeding of patients were related to the blood supply of the mass (OR=5.280, 95%CI: 1.335-20.858, P=0.018) and the largest diameter of the mass (OR=1.060, 95%CI: 1.010-1.120, P=0.030). The risk of readmission were related to the largest diameter of the mass (OR=1.055, 95%CI: 1.005-1.108, P=0.030) and the depth of the uterus cavity (OR=1.583, 95%CI: 1.015-2.471, P=0.043). No serious complications such as intestinal and nerve injury occurred during and after FUAS treatment. Conclusions: FUAS combined with suction curettage is safe and effective in treating patients with mass-type CSP through this preliminary study. The volume of vaginal bleeding are associated with the blood supply of the mass and the largest diameter of the mass, the risk of readmission are related to the largest diameter of the mass and the depth of the uterus cavity.

RESUMO

Objective: To retrospectively analyze the pregnancy outcomes of patients with adenomyosis requiring fertility in a single center under real world condition. Methods: From June 2015 to May 2020, 231 cases of pregnancy complicated with adenomyosis diagnosed by ultrasound with fertility requirements were treated in the Women's and Children's Hospital Affiliated to Qingdao University with complete clinical data. And they were divided into three groups according to the treatment of adenomyosis before pregnancy: expectation group, drug group and operation group. The relevant data before pregnancy of the three groups were analyzed, and the pregnancy outcomes of the patients were summarized. According to whether the early pregnancy was treated with medication, the patients who were naturally conceived without symptoms of threatened abortion were divided into observation group and fetus protection group, and the pregnancy outcomes of the two groups were compared. Results: (1) Compared with the expectation group, the ages of patients in the drug group and the operation group were larger [(31.5±1.8) vs (34.1±3.7) vs (36.9±3.6) years old], and the difference was statistically significant (P<0.05). Only 9 patients (11.5%, 9/78) had clinical symptoms in the expectation group, while the patients in the drug group and the operation group had a higher proportion of dysmenorrhea and increased menstrual volume. The uterine volume of the drug group and the operation group were larger than that of the expectation group [(151±46) vs (166±27) vs (97±18) cm3], the difference was statistically significant (P<0.05). 78.6% (33/42) of the operation group were focal adenomyosis. The proportion of natural pregnancy in the expectation group was 97.4% (76/78), and in vitro fertilization and embryo transfer was mainly used in the drug group and the operation group. (2) The abortion rates of the three groups were 48.7% (26/111), 4/17, 67.5% (27/78) respectively. Compared with the drug group and the operation group, the preterm birth rate was lower [55.9% (33/111) vs 11/17 vs 12.5% (5/78)] and the natural delivery rate was higher [44.1% (26/111) vs 4/17 vs 67.5% (27/78)] in the expectation group. (3) There were 89 cases of spontaneous pregnancy without threatened abortion symptoms, including 31 cases in the observation group and 58 cases in the fetus protection group. Compared with the observation group, the abortion rate of patients in the fetus protection group was lower [41.9% (13/31) vs 34.5% (20/58)], and the difference was statistically significant (P<0.05). Conclusions: Patients with adenomyosis who have fertility requirements should be comprehensively evaluated and individualized treatment plans should be given. Pregnancy patients with adenomyosis have a high rate of miscarriage, and they should be included in the management of high-risk pregnant women. Active fetal protection treatment during early pregnancy might improve pregnancy outcomes.

RESUMO

Objective: To investigate the clinicopathological features and treatment strategies of pituicytoma. Methods: Twenty-one cases of pituicytoma were collected at the First Affiliated Hospital of Nanjing Medical University and Jinling Hospital, Nanjing, China from 2009 to 2020. The clinical data of 21 pituicytoma patients was retrospectively analyzed, and the relevant literature was reviewed. Results: Twenty-one patients aged 4 to 68 years, including 8 males and 13 females. All patients underwent surgical treatment. Histologically, the tumor was consisted almost entirely of elongate, bipolar spindle cells arranged in a fascicular or storiform pattern. Mitotic figures were rare. Immunohistochemically, tumor cells were diffusely positive for S-100 protein (21/21), vimentin (15/15) and TTF1 (14/14), while they were weakly or focally positive for GFAP (13/16) and EMA (6/12). CKpan was negative in all cases and Ki-67 proliferation index was low (<5%). Among the 18 patients with follow-up, all survived and 2 relapsed after surgery. Conclusions: Pituicytoma is a rare low-grade glioma of the sellar area. It is easily confused with other sellar tumors. Preoperative diagnosis is difficult. It needs to be confirmed by histopathology and immunohistochemistry. Microsurgery is the main treatment method at present.

RESUMO

Objective: To investigate the diagnostic role of NR4A3/NOR-1 immunohistochemistry in acinic cell carcinoma (AciCC) of the salivary gland. Methods: A total of 142 tumors were collected from 2004 to 2020 at Nanjing Jinling Hospital, including 24 cases of AciCCs, 12 salivary gland secretory carcinomas,14 salivary duct carcinomas,16 adenoid cystic carcinomas,3 basal cell carcinomas,13 mucoepidermoid carcinomas,7 myoepithelial carcinomas,15 pleomorphic adenomas,15 warthin tumor, 8 myoepithelioma,8 basal cell adenomas, and 7 oncocytomas; 28 normal salivary gland tissues and 2 pancreatic AciCC were also included. Results: NR4A3/NOR-1,a nuclear marker,was positive in 91.7% (22/24) of AciCC of the salivary gland,while DOG1,a membranous and cytoplasmic marker, demonstrated a sensitivity of 95.8% (23/24);there was no significant difference in the overall positive rates(P=0.551), but the stain pattern was different. NR4A3/NOR-1 was negative in normal salivary gland tissues and any other types of tumors in the salivary gland; however,DOG1 showed apical staining in the acinar cells in the salivary gland,as well as salivary gland secretory carcinomas,adenoid cystic carcinomas,basal cell carcinomas,mucoepidermoid carcinomas,myoepithelial carcinomas and basal cell adenomas(P<0.001). NR4A3/NOR-1 showed a high sensitivity(91.7%) and specificity(100%) to identify AciCC of the salivary gland,and in combination with DOG1, the sensitivity increased to 100%. Furthermore, NR4A3/NOR-1 were only positive for AciCC arising from salivary glands but not pancreas(0/2)(P=0.018). Conclusion: NR4A3/NOR-1 is a special and sensitive biomarker for AciCC of salivary glands; combined NR4A3/NOR-1 and DOG1 can be an ideal diagnostic immunohistochemical panel for AciCC.

RESUMO

Objective: To investigate the clinical manifestations, imaging features, clinicopathologic features, and differential diagnosis of solitary fibrous tumors/anginoblastomas (SFT/HPCs) originating in the central nervous system. Methods: Sixty cases of SFT/HPCs originating in the central nervous system were collected at Nanjing Jinling Hospital, from January 1, 2008 to December 31, 2016. The clinical data, imaging data, histomorphologic changes and immunohistochemical finding were analyzed in the sixty cases. Results: The 60 cases included 26 males and 34 females, aged 14 to 85 (median 49) years. The main clinical manifestations were headache, dizziness with nausea and vomiting. Radiologically, the tumors were large, enhancing, solid and cystic masses attached to the dura. Histopathologically, the neoplasms were composed of spindle cells with oval nuclei, inconspicuous nucleoli and moderate amount of eosinophilic cytoplasm arranged in fascicles with areas of hyalinized stroma, myxoid changes and a staghorn vascular pattern. Immunohistochemically, tumor cells of all cases were positive for vimentin (100.0%, 60/60), STAT6 (98.3%, 59/60), CD34 (61.7%, 37/60), and the tumor cells were typically positive for CD99, bcl-2, EMA and SSTR2 as well.Negative for S-100 protein, SOX10, E-cadherin, GFAP. Ki-67 index ranged from 1% to 50%. Forty cases were followed up for 6 to 82 months with average of 40 months, 30 patients were alive and 10 patients died. Conclusions: Central nervous system SFT/HPCs can be aggressive and relapses may occur several years after diagnosis. STAT6 is highly sensitive and specific for the diagnosis. Complete tumor resection is optional treatment followed by radiotherapy and chemotherapy. There is a correlation between the prognosis and the location of the disease, the histological grade, Ki-67 index, and fusion gene variants.

RESUMO

Objective: To study the clinicopathologic characteristics and diagnostic criteria of primary mediastinal B-cell lymphoma (PMBL), and to distinguish PMBL from classic Hodgkin lymphoma(CHL) and systemic diffuse large B-cell lymphoma(DLBCL). Methods: The clinical features, histologic findings, results of immunohistochemical study and prgnosis in 27 PMBL cases were analyzed, with review of literature. Results: The age of patients ranged from 19 to 82 years (median age 34 years). All cases were located in the mediastinum and frequently accompanied by superior vein cava syndrome. Histologically, the tumor cells were pleomorphic and diffusely distributed. Clear cytoplasm and spindle tumor cells were seen in some cases. Varying amount of sclerosing stroma with collagen deposition was seen.Immunohistochemical study showed that the tumor cells were positive for CD20(100%, 27/27), CD30 (64.0%, 16/25), CD23 (77.3%, 17/22) and p63 (16/19). Clonal B cell gene rearrangement was seen. Conclusions: PMBL is a subtype of diffuse large B-cell lymphoma with various histomorphology. Immunohistochemistry can help to confirm the diagnosis, and the prognosis is better than diffuse large B cell lymphoma, not otherwise specified.

RESUMO

OBJECTIVE: To determine whether color doppler ultrasonography (CDU), thyroid function or thyroid autoimmune antibodies could identify Graves' disease in pregnancy(GDP) in pregnant patients with newly diagnosed thyrotoxicosis. METHODS: It is an observational study. Sixty-eight pregnant patients with newly diagnosed thyrotoxicosis including gestational hyperthyroidism(GHT) subjects (GHT group, n=33) and GDP subjects (GDP group, n=35), and 62 age-and sex-matched healthy subjects (C1 group: pregnant, n=32, C2 group: non-pregnant, n=30) were recruited. Thyroid function, human chorionic gonadotropin(HCG), thyroid autoimmune antibodies were detected. Peak systolic velocity of the superior thyroid artery (STA-PSV) and diastole inner diameter(STA-D) of the superior thyroid artery were measured by CDU. A ROC curve was used to evaluate STA-PSV, STA-D, thyroid function and thyroid autoimmune antibodies for identification of GDP. RESULTS: The area under the ROC curve of STA-PSV, STA-D and thyroid stimulating hormone (TSH), free T4 (FT4) for GDP were 0.905, 0.887, 0.803 and 0.786, respectively. The optimal cut-off points of STA-PSV, STA-D, TSH and FT4 for GDP were 40 cm/s, 2.0mm, 0.03 mIU/L and 30 pmol/L with the sensitivity of 82.9%, 72.1%, 81.8%, 76.2% and specificity of 81.8%, 87.9%, 75.2%, 80.3%, respectively. CONCLUSIONS: Detection of STA-PSV and STA-D by CDU, as well as thyroid function, is useful in screening GDP in pregnant patients with thyrotoxicosis.

RESUMO

OBJECTIVE: To analyze the correlation between glycolipids metabolism and clinicopathologic features in patients with gastric cancer. METHODS: Glycolipids metabolism and clinicopathologic features of 443 gastric cancer patients were collected, and their correlation was analyzed. RESULTS: Compared to gastric cancer patients with normal levels of glycolipids metabolism, there were less male patients who were with low level of total cholesterol (TCH)(χ(2)=7.676, P<0.05), and the number of male patients with low level of high-density lipoprotein (HDL) (χ(2)=7.520) and apoA1 (χ(2)=6.253) was higher (both P<0.05). Serum TCH level showed a negative correlation with age of patients (r=-0.116), tumor size (r=-0.117) and TNM stage (r=-0.111) (P<0.05); serum HDL level was negatively correlated with tumor diameter (r=-0.094), the number of metastatic lymph nodes (r=-0.106), primary tumor invasion depth (r=-0.112), metastatic lymph nodes stage (r=-0.102) and TNM stage (r=-0.107) (P<0.05); serum LDL was negatively correlated with age of patients (r=-0.116) (P<0.05); serum LPa was positively correlated with tumor size (r=0.170), the number of metastatic lymph nodes (r=0.151), primary tumor invasion depth (r=0.160), metastatic lymph nodes stage (r=0.153) and TNM stage (r=0.115) (P<0.05); apoA1 was negatively correlated with distant metastasis (r=-0.168) and TNM stage (r=-0.120) (P<0.05); and apoB was negatively correlated with distant metastases (r=-0.132, P<0.05). Levels of blood glucose and TG had no significant association with clinicopathological features of gastric cancer patients (P>0.05). CONCLUSIONS: Low lipid metabolism but high level of LPa may be the metabolic characteristics of gastric cancer progression. Monitoring the changes of serum lipids levels could be valuable for the prognosis of patients with gastric cancer.

RESUMO

Objective: To study the correlation between MGMT expression, clinicopathologic features and post-chemotherapy prognosis in patients with primary central nervous system lymphoma diffuse large B-cell lymphoma (PCNS-DLBCL). Methods: MGMT expression was detected in 76 cases of PCNS-DLBCL by EnVision method with immunohistochemical staining.Follow-up data including treatment response and overall survival time, were analyzed. Results: The rate of MGMT expression in PCNS-DLBCL was 67.1%(51/76). The MGMT expression rate in male patients was higher than that in female(P<0.05). Univariate analysis showed that these clinical pathological characteristics affected the overall survival of PCNS-DLBCL patients, including age and Hans algorithm, although no statistical significance was detected(P value was 0.065 and 0.069 respectively). The overall survival of the patients with positive MGMT and aged over 60 years was shorter after chemotherapy than those without chemotherapy (P=0.022). In the patients aged over 60 years, the prognosis of MGMT-positive patients was significantly better than MGMT-negative patients (P=0.044). Conclusions: The expression of MGMT is more commonly found in male patients. In the patients aged over 60 years with the same therapy, the prognosis is better in the MGMT-negative ones. Detection of MGMT protein expression can provide some guidance in choice of treatment modalities in PCNS-DLBCL patients.

RESUMO

OBJECTIVE: To investigate the clinicopathologic characteristics, differential diagnosis and prognosis of pulmonary epithelioid hemangioendotheliomas (PEHs). METHODS: The clinical symptoms and imaging findings of 6 cases of PEHs were investigated and pathologic analyses including histomorphologic and immunohistochemical studies were performed. RESULTS: Clinical symptoms of the patients were nonspecific and insidious. The typical radiological manifestation was characterized by multiple small pulmonary nodules. The pathological findings were well-demarcated hypocellular hyalinized nodules with more cellularity at the periphery of the nodule. The neoplastic cells showed mild nuclear atypia and prominent eosinophilic cytoplasm with vacuoles, attempting to form primitive vasculature. Immunohistochemically, tumor cells were positive to CD31, CD34 and ERG. Follow-up data from 8 months to 5 years showed no tumor progression, except for the development of bone metastases in one case at 6 months. CONCLUSIONS: PEHs are uncommon vascular tumors with low-intermediate malignancy. Using H&E and immunohistochemistry, the final pathological diagnosis can be made and misdiagnosed as a benign fibrotic nodule or other malignant tumors can be avoided. The most effective treatment is surgical resection, if necessary, combined with chemotherapy or radiotherapy.

RESUMO

Maize with high grain protein and oil contents offers great advantages for human food and animal feed. In this study, grain protein contents of 282 and 263 F7:8 recombinant inbred lines (RILs) of 2 crosses were evaluated in 4 environments within and between populations. The RILs were developed from crosses between an inbred high-oil maize line and 2 normal dent inbred maize lines. A total of 16 single-population QTLs and 19 joint-population QTLs were identified for protein content, and 21 QTLs were detected for protein-oil in each of the 4 environments tested and in combination. Most of the QTLs for protein content were greatly influenced by variation among populations and environments. Seven QTLs showed generational consistency compared with QTLs detected in the 2 F2:3 populations. However, 7 and 6 QTLs were detected in only the RIL and F2:3 populations, respectively. Protein and protein-oil QTLs with the same parental effects were detected at bins 3.03-3.05, 5.04-5.06, 6.03-6.05, 8.03-8.04, and 8.04-8.06, demonstrating that tightly linked and/or pleiotropic QTLs are controlling both traits at these bins. Four single-population QTLs and 11 joint-population QTLs identified at bins 3.02-3.03, 3.05, 7.01, 8.02, 8.03, 8.04-8.05, 8.05, 9.03, and 9.05 with intervals <5 cM could be used in marker-assisted selection. Along with the previously detected QTLs qPRO1-8-1 and qPRO1-5-1 at bins 8.03-8.04 and 5.02-5.04, the QTLs detected herein could be used to develop near isogenic lines and chromosome segment substitution lines in future studies.

RESUMO

A 62-year-old immunocompetent rural woman who represents an isolated cryptococcal skull infection without systematic involvement is described. Diagnosis was based on positive India ink staining, positive histopathologic examination, and positive culture. Species identification was performed by growth on Sabouraud dextrose agar and CHROMagar medium and by sequencing of the intergenic and internal transcribed spacer regions of the rRNA genes. This case describes a rare presentation of Cryptococcus neoformans infection in a human immunodeficiency virus-negative patient. The lesions were significantly improved with treatment of daily oral itraconazole 400 mg. A maintenance therapy with a low-dose itraconazole was prescribed to warrant a clinical and mycological eradication. A two-year follow-up did not show any recurrence of infection.

RESUMO

Objective: To compare the clinical characteristics and outcomes of patients newly diagnosed with multiple myeloma(NDMM)with bone-related extramedullary(EM-B)disease and those with extraosseous extramedullary(EM-E)disease and to address their prognostic factors. Methods: The clinical features, outcomes, and prognostic factors were retrospectively analyzed in 80 patients with NDMM with extramedullary disease. Results: Among 80 patients with extramedullary disease, 51 had EM-B and 29 EM-E. The level of ß(2)-microglobulin(5.82 mg/L vs 3.99 mg/L, P=0.030), lactate dehydrogenase(256 U/L vs 184 U/L, P=0.003), 1q21 amplification rate(78.6% vs 53.1%, P=0.035), and Ki-67 proliferation index(50% vs 25%, P=0.002)in the EME group were significantly higher than those in the EM-B group. The posieive rate of CD56(14.3% vs 66.7%)and overall response rate(60% vs 82.3%)in EM-E group were significantly lower than those in EM-B group. The median overall survival (OS)of patients with EM-E and EM-B was 14.5 and 49.5 months, and the median progression-free survival(PFS)of the two groups was 9.0 and 18.0 months. Patients with EM-E had a significantly shorter OS(P=0.035)and PFS(P < 0.001)than those of patients with EM-B, whereas the PFS did not significantly differ(P=0.263)when patients accepted proteasome inhibitor(PI)-based regimens for induction therapy. Multivariate analysis with Cox model showed the best response that did not achieve partial response(PR)was an independent poor prognostic factor for both OS and PFS in NDMM patients with EM-E(P=0.031, P=0.005), ISS-III, and the best response that did not achieve PR were independent prognostic factors for the shorter OS in patients with NDMM with EM-B(P=0.009, P=0.044). Conclusions: The clinical characteristics and outcomes of patients with NDMM with EM-E are different from patients with EM-B. Outcomes of patients with EM-E is significantly poor. PI induction therapy improved the PFS of patients with EM-E.

RESUMO

OBJECTIVES: The oldest old population has become the fastest growing segment with excess need of care and social support, it is crucial to improve the health-related quality of life (HRQoL) of these populations. This study seeks to evaluate the health status and to investigate modifiable factors associated with health-related quality of life for oldest old adults in China. DESIGN: A cross-sectional population-based study. SETTING: Hainan Province in the south of China. PARTICIPANTS: 1,278 adults aged 80 years or older. METHODS: HRQoL was assessed by three-level EuroQol-5D scale (EQ-5D-3L) and a visual analogue scale (VAS). Demographic and health-related variables were analysed by estimating mean values and standard deviations for continuous variables, percentages and standard deviations for categorical variables. Tobit regressions, ordinary least Squared (OLS) regressions and ordered probit regressions were adopted to determine the associated factors for overall HRQoL and for each health dimension. RESULTS: Anxiety/depression was the least reported problem while mobility was the most frequently reported with problem. Female respondents had lower EQ-5D score (0.76 vs. 0.86) and VAS score (66.55 vs. 69.84) than male respondents. Better health-related quality of life was significantly associated with higher BMI, no drinking habit, more leisure activities, living with family members, good sleeping quality, closer social and family connections, fewer numbers of drugs consumed per day, without having hearing or visual impairment, and fewer chronic conditions, after controlling for potential confounders. CONCLUSION: Findings from this study suggested that quality of life was not only associated with age-related diseases, but also correlated with a range of health-related lifestyles, and factors indicating social and family support.

RESUMO

Summary A 9 year-old boy suffering from cough for half a month, fever for 4 days was hospitalized. CT three-dimensional reconstruction showed that a metallic needle-like foreign body within the right main bronchial with pneumonia and atelectasis. In the next day, the boy took examination using an open-tube rigid bronchoscope under general anesthesia. For the first time, the foreign body was jammed in glottis with SpO2 and HR declining. For the second time, the operator found the foreign was not a needle but a thumbtack. Finally, the thumbtack was removed from the airway after short-term paralysis using succinylcholine.
