目的：探讨体部伽玛刀联合长春瑞滨、顺铂治疗局部晚期非小细胞肺癌的临床疗效及不良反应。方法：自2008年1月-2010年7月,对101例非小细胞肺癌患者按治疗方法分为伽玛刀联合长春瑞滨、顺铂（联合组）52例和单纯应用长春瑞滨、顺铂（对照组）49例,比较两组治疗后的近期疗效、生存期及不良反应。结果：联合组、对照组有效率分别为82．69％和53．06％,两组1年生存率分别为69．23％,42．86％。联合组的急性放射性肺损伤发生率11．54％,急性放射性食管损伤发生率9．62％,均为1—2度。两组的血液毒性主要表现为白细胞下降,另外还合并有恶心、呕吐等,联合组发生几率明显高于对照组,但经过对症治疗均能顺利完成治疗。结论：伽玛刀联合长春瑞滨、顺铂治疗能显著提高局部晚期肺癌患者的近期疗效、生存时间;白细胞下降、恶心、呕吐等不良反应较单纯化疗组也明显增加,有部分患者还会出现急性放射性肺损伤,急性放射性食管损伤,但经过对症处理基本恢复正常不影响治疗。     

Laparoscopic findings in female genital tuberculosis

OBJECTIVES: To evaluate the laparoscopic findings in genital tuberculosis (TB). METHODS: A total of 85 women of genital TB, who underwent diagnostic laparoscopy for infertility or chronic pelvic pain were enrolled in this retrospective study conducted in our unit at All India Institute of Medical Sciences, New Delhi, India from September 2004 to 2007. RESULTS: The mean age was 28.2 years and the mean parity was 0.24. Most women were from poor socioeconomic status (68.1%). Past history of TB was seen in 29 (34.1%) women with pulmonary TB in 19 (22.35%) women and extrpulmonary in 10 (11.7%) women. Most women presented with infertility (90.6% primary 72.9%; secondary 17.6%) while the rest had chronic pelvic pain (9.4%). The mean duration of infertility was 6.2 years. A total of 49 (57.6%) women had normal menses, while hypomenorrhea, oligomenorrhea, secondary amenorrhea and menorrhagia were seen in 25 (30.1%), 3 (3.5%), 5 (5.9%), and 2 (2.4%) women respectively. Diagnosis of genital TB was made by histopathological evidence of TB granuloma in 16 (18.8%) (Endometrial biopsy in 12.9%, laparoscopy biopsy in 5.9%) women, demonstration of acid fast bacilli (AFB) on microscopy in 2(2.3%), positive AFB culture in 2 (2.3%), positive polymerase chain reaction (PCR) in 55 (64.7%) and laparoscopic findings of genital TB in 40 (47.1%). The various findings on laparoscopy were tubercles on peritoneum (12.9%) or ovary (1.2%), tubovarian masses (7.1%), caseous nodules (5.8%), encysted ascitis in 7.1% women. Various grades of pelvic adhesions were seen in 56(65.8%) women. The various findings on fallopian tubes were normal looking tubes in (7.1%), inability to visualize in 12(14.1%), presence of tubercles on tubes in 3 (3.52%), caseous granuloma in 3 (3.52%), hydrosalpinx in 15 (17.6%) (Right tube 11.7%, left tube 5.9%), pyosalphinx in 3 (3.5%) on right tube and 2 (2.35%) in left tube, beaded tube in 3 (3.5%) on right tube, 4 (4.7%) in left tube with tobacco pouch appearance in 2 (2.35%) women. The right tube was patent in 9 (10.6%) while left tube was patent in 10(11.7%) cases only, while they were either not seen (absent in one case due to previous salphingectomy, inability to see due to adhesion in 14.12%) or blocked at various sites with cornual end being most common in 3 (3.5%) showing multiple block in right tube and 4.7% in left tube. CONCLUSION: There is a significant pelvic morbidity and tubal damage in genital tuberculosis.

Effects of an Amino Acid-Based Formula Supplemented with Two Human Milk Oligosaccharides on Growth,Tolerability, Safety,and Gut Microbiome in Infants with Cow’s Milk Protein Allergy

This open-label, non-randomized, multicenter trial (Registration: {"type":"clinical-trial","attrs":{"text":"NCT 03661736","term_id":"NCT03661736"}}NCT 03661736) aimed to assess if an amino acid-based formula (AAF) supplemented with two human milk oligosaccharides (HMO) supports normal growth and is well tolerated in infants with a cow’s milk protein allergy (CMPA). Term infants aged 1–8 months with moderate-to-severe CMPA were enrolled. The study formula was an AAF supplemented with 2′-fucosyllactose (2′-FL) and lacto-N-neotetraose (LNnT). Infants were fed the study formula for 4 months and were offered to remain on the formula until 12 months of age. Tolerance and safety were assessed throughout the trial. Out of 32 infants (mean age 18.6 weeks; 20 (62.5%) male), 29 completed the trial. During the 4-month principal study period, the mean weight-for-age Z score (WAZ) increased from –0.31 at the baseline to +0.28 at the 4-months’ follow-up. Linear and head growth also progressed along the WHO child growth reference, with a similar small upward trend. The formula was well tolerated and had an excellent safety profile. When comparing the microbiome at the baseline to the subsequent visits, there was a significant on-treatment enrichment in HMO-utilizing bifidobacteria, which was associated with a significant increase in fecal short-chain fatty acids. In addition, we observed a significant reduction in the abundance of fecal Proteobacteria, suggesting that the HMO-supplemented study formula partially corrected the gut microbial dysbiosis in infants with CMPA.
