OBJECTIVESTo summarize the clinical results in the treatment of spinal tuberculosis with debridement, bone grafting and anterior fixation and to evaluate the safety and the value of this procedure.

METHODSFrom June 1997 to May 2001, 18 patients with spinal tuberculosis were treated using anterior debridement, autograft of bone and primary internal instrumentation. They were 8 men and 10 women, aged from 25 to 59 years (mean 41 years). The degree of kyphosis before surgery was 27.0 degrees to 75.5 degrees (mean 47.5 degrees +/- 11.4 degrees ). The involved spines included cervical spine (1 patient), thoracic spine (10), thoracic-lumbar spine (2), and lumbar spine (5). Average 2.8 intervertebral bodies in each patient were afflicted with tuberculosis disease. Spinal fusions were done with iliac bone grafts.

RESULTSAll patients were followed up for an average of 25 months. No deep wound infection and sinus were observed after surgery. The grafted bones were fused in all patients with an average time of 3.6 months. The degree of spine kyphosis correction was 32.7 degrees +/- 8.3 degrees, and 3.2 degrees +/- 2.8 degrees was lost on average in the late stage.

CONCLUSIONAnterior instrumentation for spinal tuberculosis could stabilize the spine, correct kyphosis and fuse the grafted bone.

Objective:To explore the value of jellyfish sign, an abnormal ultrasonographic sign, in predicting adverse perinatal outcomes of women with complete placenta previa combined with placenta accreta spectrum disorders (PAS).Methods:This retrospective study analyzed the ultrasound images of 72 singleton gravidas, diagnosed with complete placenta previa combined with PAS, who underwent cesarean section at the First Affiliated Hospital of Nanjing Medical University between January 2020 and February 2023. Based on the presence and absence of the jellyfish sign in ultrasound images, these gravidas were divided into the jellyfish-sign group (15 cases, 20.8%) and the non-jellyfish-sign group (57 cases, 79.2%). The clinical data and perinatal outcomes of the two groups were analyzed. The adverse perinatal outcomes encompassed conditions such as abdominal aorta balloon block, uterine artery embolism, hysterectomy, postpartum hemorrhage, and neonatal intensive care unit (NICU) admission of their neonates. Statistical analysis was performed using two independent samples t-test, the Mann-Whitney U test and the Chi-square (or Fisher's exact) test. Results:(1) The jellyfish-sign group exhibited a higher parity [(1.6±0.7) times vs (1.2±0.6) times, t=2.01] and higher prenatal scores of placenta accreta [(12.3±1.5) scores vs (8.6±2.9) scores, t=6.59] than those in the non-jellyfish-sign group (both P<0.05). Among the 57 cases in the non-jellyfish-sign group, there were 14 cases of placenta creta (24.6%), 40 cases of placenta increta (70.2%), and three cases of placenta percreta (5.3%). Among the 15 cases in the jellyfish-sign group, nine cases were diagnosed with placenta increta, six with placenta percreta, and none with placenta creta. The difference in distribution between the two groups was statistically significant (Fisher's exact test, P<0.001). (2) Intraoperative blood loss [(for those who accepted abdominal aorta balloon block, 1 973±1 057) ml vs (1 211±576) ml, t=2.55], red blood cells transfused [4.0 U (2.0-23.0 U) vs 2.5 U (0.0-11.0 U), Z=－2.53], postoperative hospitalization time [(9.7±2.4) vs (7.5±2.2) d, t=3.36], the incidence of abdominal aorta balloon block [15/15 vs 38.6% (22/57), χ2=17.92], uterine artery embolism [for those who accepted abdominal aorta balloon block, 3/15 vs 1.8% (1/57), Fisher's exact test], and requiring blood transfusion [15/15 vs 63.2% (36/57), Fisher's exact test] were higher in the jellyfish-sign group than those in the non-jellyfish-sign group. However, the non-jellyfish-sign group had lower gestational age at delivery [(33.6±1.5) weeks vs (35.2±1.8) weeks, t=－3.24], and lower neonatal Apgar score at 1 min and 5 min [1 min: 8 scores (3-10 scores) vs 9 scores (4-10 scores), Z=－2.46; 5 min: 9 scores (7-10 scores) vs 10 scores (6-10 scores), Z=－2.02] (all P<0.05). There were no significant differences in emergency surgery rate, 24 h postoperative blood loss, neonatal birth weight, and proportion of NICU admission between the two groups. Additionally, no cases of hysterectomy or death were observed in the two groups. Conclusions:Ultrasound examination revealing jellyfish signs in patients with complete placenta previa and PAS is associated with an increased likelihood of adverse perinatal outcomes. Consequently, the management of these patients should be given greater attention.
