Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(24):1996-1997
We report a case of a 47-year-old man who firstly complained of throat pain for half a month accompanied with fever. Specialized examination showed tonsils' hypertrophy and the laryngoscope found his right vocal cord was swelling and hyperemia. The routine blood test counted white blood cell as 31 x 10(9)/L, lymphocyte as 30. 84 x 10(9)/L while prolymphocyte could be seen with microscope. After that B-ultrasound scan gave spleen hypertrophy and multi-lymphatic-node enlargement. Peripheral blood flowcytometry and bone marrow biopsy finally diagnosed the man as actue myelocytic leukemia.

Abstract
On April 25, 2021, a case with hookworm infections was identified during the surveillance of soil-borne nematodiasis by Tiantai Center for Disease Control and Prevention, Taizhou City, Zhejiang Province. The patients was admitted to a county people's hospital due to dizziness and limb weakness on July 24, 2020. Laboratory tests showed 2.5×1012/L red blood cell counts, 45 g/L hemoglobin, 3.4% eosinophil percentage, 4.7 μmol/L serum iron and <1 μg/L ferritin, and severe iron-deficiency anemia was initially diagnosed. Following treatment with blood transfusion and ion supplement, subsequent three routine blood tests indicated elevated eosinophil percentages. On April 25, 2021, hookworm eggs were detected in stool samples using Kate-Katz technique, and Necator americanus was identified with the test-tube filter-paper culture method. Severe iron-deficiency anemia caused by hookworm infections was diagnosed based on field epidemiological surveys and laboratory tests. The health education pertaining to parasitic disease control knowledge among residents and the diagnosis and treatment of parasitic diseases in medical institutions are recommended to be improved in rural areas to avoid misdiagnosis and missing diagnosis.

Objective To evaluate the high?risk factors for brain metastases after prophylactic cranial irradiation ( PCI), and to provide a basis for personalized treatment. Methods A retrospective analysis was performed in 188 patients with limited?stage small?cell lung cancer who received PCI in our hospital from 2005 to 2010. The Kaplan?Meier method was used to calculate the cumulative rate of brain metastases. The log?rank test and the Cox model were used for the univariate and multivariate analyses of the potential factors for the cumulative incidence of brain metastases, respectively. Results In the 188 patients, 31 ( 16?5%) had brain metastases. The 1?, 2?, and 3?year cumulative incidence rates of brain metastases were 4%, 15%, and 20%, respectively. The univariate analysis showed that staged Ⅲ disease before treatment, elevated levels of tumor markers, incomplete remission after chemoradiotherapy, and local?regional relapse were risk factors for high incidence of brain metastases ( P= 0?044, 0?037, 0?005, 0?007) . The multivariate analysis revealed that incomplete remission after chemoradiotherapy and local?regional relapse after chemoradiotherapy were risk factors for high incidence of brain metastases after PCI ( P= 0?003, 0?040 ) . Conclusions Patients with incomplete remission or local?regional relapse after chemoradiotherapy have high incidence of brain metastases after PCI. For those patients, a frequent follow?up of the central nervous system plus salvage cranial irradiation might provide an alternative to PCI.

Objective To understand the prevalence of group sex in men who have sex with men (MSM) and related factors in Taizhou,Zhejiang province.Methods From March 2013 to September 2015,a cross-sectional survey was conducted among MSM recruited from gay bars or bath houses in Taizhou by using questionnaire to collect the information about their sexual behavior and HIV test.Results A total of 1 435 MSM were recruited,179 of them (12.5%) were HIV infected,231 (16.1%) reported group sex during the past year.Compared with MSM without group sex,more MSM with group sex had more than ten male sexual partners (53.7% vs.19.0%,x2=125.527,P< 0.01),had both male and female sexual partners (86.6% vs.68.2%,x2=31.935,P<0.01),used no condom at sex with female partners during the past year (28.1% vs.19.8%,x2=6.540,P<0.05).After adjusted for educational level and occupation,group sex was associated with age [≥ 50 years old vs.≤ 24 years old,adjusted odds ratio (aOR)=2.25,P=0.027],marriage with female (divorced or widowed vs.unmarried,aOR=0.29,P=0.001),census registering (local resident vs.non-local resident,aOR=1.56,P=0.023),number of male seuxal partners (≥21 vs.2-5,aOR=8.06,P<0.001;11-20 vs.2-5,aOR=3.25,P<0.001) and number of female seuxal partners (≥6 vs.0,aOR=2.63,P=0.005;2-5 vs.0,aOR=2.58,P=0.001;1 vs.0,aOR=2.01,P=0.010).Conclusion The prcvalcncc of group sex in MSM was high in Taizhou,and their poor condom use and complex sex behaviors would result in higher HIV infection rate and risk of transmission.

Objective:
To determine the first dengue fever case in Taizhou and trace probable transmission sources.
Methods:
Collected serum of three patients for antigen, antibody and nucleic acid detection. Dengue viruses were isolated and cultured in C6/36 cell. The whole length of E gene was amplified by reverse transcriptase-polymerase chain reaction(RT-PCR) and then sequenced. The phylogenetic tree was drawn.
Results:
Three cases were positive in nucleic acid detection. Two cases were IgM positive. One case was NSI antigen postive. Three strains of type I dengue virus were isolated from samples. The phylogenetic trees shown that the three strains were on the same branch. The identities of nucleotide were 99.87%. The identities of amino acid were 99.6%-99.8%.
Conclusions
The dengue virus strains isolated in Taizhou was imported from Guangdong or Southeast Asia and caused location infection.

UNLABELLEDObstract: To characterize and analyze risky sexual networks and genetic scales to potential HIV transmission for HIV seroconcordant couples in Taizhou municipality of Zhejiang Province.
METHODSHIV seroconcordant positive couples were invited as index cases to participate in an egocentric survey on HIV related risky behavior and behavioral network prior to HIV diagnosis during 2008-2011. Within-couple HIV transmission pairs were determined by the combination of both behavioral and phylogenetic analysis.
RESULTSTotally 27 HIV seroconcordant couples were enrolled in this study. Male spouses were more likely to report having two or more sexual partners in the past years prior to HIV diagnosis than female spouses (88.9% vs. 37.0%). Among 27 couples, 20 couples including 17 couples by male but not female spouses, 3 couples by female but not male spouses reported having two or more sexual partners (i.e., multiple sexual partners) prior to HIV diagnosis; and 7 couples by both spouses reported having multiple sexual partners. Twenty four of 27 sexual networks were determined to be HIV transmission pairs (20) or potential transmission pairs (4), 3 couples were subtyped with discordant HIV subtypes or large genetic distance and thus had different sources of HIV transmissions. In addition, among 27 concordant couples, HIV drug resistance (HIVDR) or primary HIVDR existed in 6 ART-naïve participants in 4 networks; among them, 2 networks were determined to be potential HIVDR transmission couple pairs.
CONCLUSIONSThe HIV strains isolated in HIV infected spouses characterized with diversity and CRF01_AE was the main strain subtype. One of the spouses with risky behavior infected HIV was the main route of transmission to other spouses through unprotected sexual contacts. HIVDR was isolated from some HIV infected individuals, suggesting the risk for HIVDR transmission in married couples. The results provide enhanced evidence for urgent development of tailored prevention strategies, such as couple-based HIV counseling and testing services to reduce HIV secondary transmission.
