Primary Intraosseous Hemangiomas of the Maxillary Bone: A Case Report and Literature Review.

Primary intraosseous hemangiomas of the maxillofacial region are rare lesions that comprise less than 1% of all osseous tumors. A review of the literature on primary intraosseous hemangiomas of the facial bones revealed a limited number of publications, much of which was largely limited to case reports. This case report summarizes the workup and surgical treatment of a 37-year-old female with a primary intraosseous hemangiomas of the left maxillary bone.

Extent of Lung Involvement and Serum Cryptococcal Antigen Test in Non-Human Immunodeficiency Virus Adult Patients with Pulmonary Cryptococcosis.

Background: Serum cryptococcal antigen (CrAg) test is the most used noninvasive method to detect cryptococcal infection. However, false-negative CrAg test is not uncommon in clinical practice. Then, the aim of this study was to investigate the factors associated with false-negative CrAg test among non-human immunodeficiency virus (HIV) adult patients with pulmonary cryptococcosis and its clinical features.

[Recurrence and surgical salvage of sinonasal squamous cell carcinoma].

Objective: To analyze the significant clinicopathologic factors related to tumor recurrence in patients with sinonasal squamous cell carcinomas (SCC) and to evaluate the effectiveness and plausibility of surgical salvage in the recurrent cases.

Methods: The clinicopatholgic data of 107 patients with primary sinonasal SCC treated from 1996 to 2007 were analyzed retrospectively. Univariate and multivariate logistic regression analyses were used to define the risk factors related to tumor recurrence.

[Application of amplitutude integrated electroencephalography for early diagnosis of brain injury in premature infants].

Objective: To study the characteristics of amplitude integrated electroencephalography (aEEG) in preterm infants with brain injury.

Methods: This study included 62 cerebral damage infants with 28-36 weeks gestational age (GA), and another 51 normal infants in control group, aEEG recording was performed to each infant during the first 48 h of life, the duration of each recording was at least 2 h. The features of aEEG, such as continuity(Co), sleep-wake cycling (Cy) and amplitude of the lower border (LB), were evaluated by semiquantitative analysis and compared between the two groups.

[Multi-modalities for reconstruction of circumferential defects in the pharyngoesophageal region].

Objective: To investigate the feasibility of multi-modalities in the reconstruction of circumferential defects after resection of cancers in pharyngoesophageal regions, and to compare the pros and cons between different surgical procedures.

Methods: According to the nature and extend of defects, five different methods including pectoralis major myocutaneous flap, laryngeal tube replacement, free jejunum, free forearm flap and gastric pull-up were used to reconstruct the circumferential pharyngoesophageal defects in 72 patients. Function of deglutition and restoration of swallowing was regularly followed up and objectively evaluated.

[Analysis of under 5 years old children mortality and the leading death cause in China from 1996 to 2000].

Objective: To study the trend of under 5 years old children mortality and the leading cause of the deaths in China from 1996 to 2000.

Methods: The data presented in this report were obtained from the national child mortality surveillance network, including 116 counties (cities) throughout China. The target population was all children under 5 years old in the monitored areas whose mothers or fathers had resided in the area for at least one year.

[Secular trends of hypospadias in Chinese perinatals].

Objective: To investigate the secular trends in the prevalence rate of hypospadias in Chinese perinatals and explore its possible influencing factors.

Methods: Data were taken from Chinese Birth Defects Monitoring Network, a hospital-based congenital anomalies registry system. All live or still births at or beyond 28 weeks of gestation were assessed within 7 days after delivery in the period from 1987 to 2001.

[Impacts of birth defects on perinatal deaths in Chinese population].

Objective: To examine the time trends of perinatal mortality and the frequency of birth defects occurring in perinatal deaths, and to provide a national perspective on the impacts of congenital anomalies on perinatal mortality from 1990 through 2001.

Methods: Data were from Chinese Birth Defects Monitoring network-a hospital-based congenital anomalies registry system. During 1990 - 2001, all live or still births with 28 weeks of gestation or more, born in monitoring units, were studied within 7 days after delivery.

[Effects of a comprehensive health education program on reproductive tract infections/sexually transmitted diseases intervention among reproductive age population in the rural areas of China].

Objective: To evaluate the effectiveness on comprehensive health education intervention program regarding reproductive tract infections/sexually transmitted diseases (RTIs/STDs) among reproductive age population in the rural areas of China.

Methods: Data were generated from the Reproductive Health/Family Planning Project implemented by the State Family Planning Committee and the Ministry of Health from 1998 to 2002, which covered 32 counties in 22 provinces. A quasi-experimental design was used.

[Clinical features of 3798 perinatals suffering from syndromic neural tube defects].

Objective: To investigate the patterns and associated malformations in neural tube defects (NTDs) cases.

Methods: From 1987 to 1995, hospital-based cluster sampling method was adopted for collecting data. During that period all live or still births with 28 weeks of gestation or more were assessed within 7 days after delivery.
