RESUMO
Diabetic ketoacidosis (DKA), a serious acute complication of diabetes mellitus, mainly manifests as hyperglycemia, ketosis, and acidosis. It is a metabolic syndrome resulting from insulin deficiency and increased insulin-antagonistic hormone levels. While type 2 diabetes mellitus complicated by DKA is relatively uncommon, secondary pneumomediastinum in DKA is extremely rare. Following alveolar rupture, air can travel through various routes to reach the hilum, causing anterior, middle, or posterior pneumomediastinum or even leading to intracranial epidural pneumatosis. The diagnosis of pneumomediastinum is mainly dependent on chest computed tomography findings. After the successful treatment of DKA, pneumomediastinum usually resolves spontaneously within 5-10 days with a good prognosis. One DKA patient admitted to Dege County People's Hospital developed Kussmaul respirations, followed by an increase in intra-alveolar pressure, an elevation in intra and extra-alveolar pressure difference, and protein decomposition in the alveolus wall, which promoted alveolar rupture and induced mediastinal emphysema. After rapid fluid replacement, blood glucose control with insulin, and maintenance of acid-base balance (correction DKA), the mediastinal emphysema was spontaneously absorbed. Through the analysis of the clinical data of this case, the purpose is to improve the clinicians' internal understanding of the relationship between mediastinal emphysema and DKA, avoid over-examination and over-treatment, and provide strategies for correct diagnosis and treatment.
RESUMO
@# As acute enterovirus⁃induced infections, herpangina(HA) and hand⁃foot⁃mouth disease(HFMD) are simi⁃lar in many aspects. Although these diseases vary with time and region, many studies have shown that the viruses caus⁃ing HA and HFMD are consistent, and there is no notable difference in partial VP1 gene sequences between different vi⁃ruses. HA and HFMD also resemble each other in epidemiological features. Both infections show significant summer⁃time seasonality, have a strong connection with certain environmental conditions and are most prevalent in young chil⁃dren and infants. Herpangina is thought to be a mild disease, defined as vesicular enanthem and then ulcers of the fau⁃ces and soft palate with presentation of feve r, sore throat, and decreased appetite. HFMD, which could lead to severe symptoms, is also characterized by oral ulcers, although they are chiefly on the buccal mucosa and tongue, and typical vesicular rashes, which are most commonly found on the hands, feet, knees and buttocks. While HA is generally be⁃ lieved to be self⁃limited and has a favorable prognosis, HA with certain clinical characteristics, such as diarrhea, vomit⁃ing, limb jitter and sleepiness, can evolve into HFMD, according to some literature in recent years. However, HA is an independent risk factor for HFMD, and severe cases only present with herpes appearing at the isthmus of the fauces at an early stage, which indicates a strong correlation between them. Clinical manifestations of HA should be considered by medical staff to identify potential children with HFMD as early as possible to prevent its further development or transformation.
RESUMO
Objective The aim of this study was to evaluate the prognosis of resection followed by chemotherapy compared with chemoradiotherapy for limited-stage small cell lung cancer .Methods The clinical data of 230 limited-stage small cell lung cancer patients with curative treatment between January 2006 and December 2011 were retrospectively analyzed .All patients divided to two group: the resection plus chemotherapy ( S +C ) and chemoradiotherapy ( R +C ) .And the prognostic factors were further analyzed with limited stage small cell lung cancer .The Kaplan-Meier method was used for the survival analysis.Results The overall survival rates of 1-year, 3-year and 5-year were 87.0%, 38.9%, 25.4%, respectively and the media survival time ( MST) 26.0 months.When patients were stratified by clinical stageⅠ+Ⅱ, the 1-year , 3-year and 5-year overall survival rates of S +C group and R +C group were 92.6%, 63.2%, 47.3%and 76.2%, 42.9%, 30.6%, respectively (χ2 =7.851, P0.05).In univariate analysis, tumor location, tumor stage, lymph node metastasis, TNM stage, the cycle of chemotherapy , treatment modalities were significantly associated with survival ( RR=1.735, P<0.05).The multivariate analysis only showed TNM stage were independent factors of prognosis .Conclusions The results suggested that resection plus chemotherapy could improve the prognosis of early-stage(stageⅠ+Ⅱ) small cell lung cancer, but patients in ⅢA stage should received the definitive chemoradiotherapy .The TNM stage was still the independent factor of prognosis .
RESUMO
[Objective]To investigate the prognostic value of 18F-FDG PET/CT with different metabolic parameters in newly diagnosed limited-disease(LD)small cell lung cancer(SCLC).[Methods]Retrospective analysis was carried out in the patients between June 2005 to December 2016 in our hospital confirmed of LD SCLC by pathology or cytology and comprehensive imaging. Fifty-four patients were recruited. Record the general characteristics of patients,pre-treatment KPS score,smoking status,weight loss,serum LDH,NSE,OS,PFS. All lesions(primary lesions + metastases)were sketched out within one VOI,and the SUVmax, SUVmean and SUVpeak in the VOI were automatically measured and recorded. The automatic measurement was performed by the fixed threshold method. The thresholds of tumor of MTV and TLG were 40% and 50% of SUVmax. The TLG and MTV were identified as TLG40%,TLG50%,MTV40% and MTV50% respectively. Kaplan-Meier method was used for survival analysis. All the prognostic factors were analyzed by Cox model.[Result]The median SUVmax was 13.92(2.61~43.28),the median of SUVmean was 8.31(1.71~26.85) and the median of SUVpeak was 10.51(1.49 ~ 27.48). The median of TLG40% was 340.22(16.58 ~ 2827.26),the median of TLG50%was 215.645(1.70 ~ 2270.36),the median of MTV40% was 36.71(1.15 ~ 259.47 cm3),the median of MTV50% was 19.65(0.93 ~1900.00)cm3. Univariate and multivariate analysis of metabolic index and prognosis showed that TLG50% was the prognostic factor of OS(P = 0.013),but not of PFS(P > 0.05). The SUVmax,SUVmean and SUVpeak were not the prognostic factors of OS and PFS(P >0.05).[Conclusion]The volume metabolic parameters TLG50%was the independent prognostic factor of the overall survival time of the LD SCLC. The volume metabolic parameters (TLG and MTV) of 18F-FDG PET/CT were related to the prognosis of SCLC ,which could provide the basis for individual chemotherapy.
RESUMO
About 30％ ～ 40％ of small cell lung cancer (SCLC) patients belong to limited disease (LD).In the setting of limited-disease small cell lung cancer (LD-SCLC),the combination of thoracic radiotherapy (TRT) with chemotherapy is the standard treatment for LD-SCLC with improved survival and local control.It is proven that prophylactic cranial irradiation can improve the prognosis of patients with SCLC.Radiotherapy should join in the early chemotherapy and individualized formulate appropriate target volume.Radiation schemes of conventional fractionation or hyperfractionation way are recommended.
RESUMO
BACKGROUND: Irinotecan hydrochloride, a topoisomerase I inhibitor, is effective against small-cell lung cancer. Irinotecan also can act as a potential radiation sensitizer along with cisplatin. To evaluate efficacy and toxicity of irinotecan plus cisplatin (IP) with concurrent thoracic radiotherapy, we conducted a phase II study of IP followed by concurrent IP plus hyperfractionated thoracic radiotherapy in patients with previously untreated limited-stage small-cell lung cancer. METHODS: Twenty-four patients with previously untreated small-cell lung cancer were enrolled onto the study since November 2004. Irinotecan 60 mg/m2 was administered intravenously on days 1 and 8 in combination with cisplatin 60 mg/m2 on day1 every 21 days. From the first day of third cycle, twice-daily thoracic irradiation (total 45 Gy) was given. Prophylactic cranial irradiation was given to the patients who showed complete remission after concurrent chemoradiotherapy. Restaging was done after second and sixth cycle with chest CT and/or bronchosocpy. RESULTS: Up to November 2004, 19 patients were assessable. The median follow-up time was 12.5 months. A total of 99 cycles (median 5.2 cycles per patient) were administered. The actual dose intensity values were cisplatin 19.6 mg/m2/week and irinotecan 38.2 mg/m2/week. Among the 19 patients, the objective response rate was 95% (19 patients), with 9 patients (47%) having a complete response (CR). The major grade 3/4 hematological toxicities were neutropenia (35% of cycles), anemia (7% of cycles), thrombocytopenia (7% of cycles). Febrile neutropenia was 4% of cycles. The predominant grade 3/4 non-hematological toxicities was diarrhea (5% of cycles). Toxicities was not significantly different with concurrent administration of irinotecan and cisplatin with radiotherapy, except grade 3/4 radiation esophagitis (10% of patients). No treatment-related deaths were observed. The 1-year and 2-year survival rate of eligible patients was 89% (16/18) and 47% (9/18), respectively. CONCLUSION: Three-week schedule of irinotecan plus cisplatin followed by concurrent IP plus hyperfractionated thoracic radiotherapy is an effective treatment for limited disease small-cell lung cancer, with acceptable toxicity.

The development of drug resistance is the major limiting factor influencing the survival of patients with small cell lung cancer (SCLC). We have thus examined the activity of cyclophosphamide, doxorubicin and vincristine (CAV) alternating with etoposide and cisplatin (EP) in 35 patients with SCLC. The treatment courses were alternated every 3 or 4 weeks. After induction chemotherapy, patients with limited disease (LD) received thoracic radiotherapy (5000 cGy), prophylactic cranial irradiation (3000 cGy) and maintenance chemotherapy and patients with extensive disease (ED) received maintenance chemotherapy only. In this group of 35 patients, 13 had limited disease (LD) and 22 had extensive disease (ED). After completion of the therapy, 100% of the patients with LD achieved complete plus partial remission (CR + PR) and 68% of the patients with ED achieved CR + PR. The median survival time was 66 weeks (15.3 months) in patients with LD and 44 weeks (10.2 months) in patients with ED. The over all survival for patients with LD was superior to that for patients with ED (p less than 0.05). Also, median response duration for patients with LD (35 wks) was longer than that for patients with ED (17 weeks) (p less than 0.05). The primary site was the most vulnerable site to relapse (18 patients). Toxicity was mild to moderate and acceptable, and there were no treatment-related deaths. These results suggest that the alternation of CAV and EP is effective treatment strategy in the management of SCLC. A randomized controlled study will be required to discriminate the actual effect of this alternating regimen.
