Toxic epidermal necrolysis; 15 years'' experience in a Dutch burns centre

BACKGROUND: Toxic epidermal necrolysis (TEN) is a severe and potentially fatal drug reaction characterized by an extensive skin rash with blisters and exfoliation, frequently accompanied by mucositis. The wounds caused by TEN are similar to second-degree burns and severe cases may involve large areas of skin loss. OBJECTIVES: Analysis of our results in patients with TEN and evaluation of the variety of therapeutic interventions that has been studied and suggested in TEN. PATIENTS/METHODS: Retrospective analysis of 19 consecutive patients with TEN treated in our burns centre between 1989 and 2004. RESULTS: Immediate withdrawal of any potentially fatal drug, maximum supportive care, and a restricted and tailored antibiotic, medical and surgical treatment regimen confined mortality to 21%, whereas prognosis scores like APACHE II and SCORTEN predicted mortality of 22 and 30%, respectively. A positive contribution of selective digestive decontamination is suggested but has yet to be established. CONCLUSIONS: Because of a potentially fatal outcome, fast referral of a patient suspected of TEN to a specialized centre (mostly a burns unit or specialized dermatology centre) for expert wound management and tailored comprehensive care is strongly advised and contributes to survival.     

女性慢性下腹痛的干预性治疗

1背景 育龄妇女常见慢性下腹痛，可造成身体损害、情绪忧伤及导致巨大的健康服务费用。美国在这方面的花费超过8亿8千万美元（Mathias 1996）。英国全国数据库的一般性诊治资料显示，慢性下腹痛发病率及流行率与偏头痛、背部痛、哮喘发病率相似（Zondervan 1999）。     

Chromogalactography preceding ductal-lobular unit excision for nipple discharge--with special reference to diagnostic galactography and histology

Between 1981-88, 223 surgical interventions were performed in cases of pathologic breast secretion after exclusion of extra-mammary aetiology. The milk duct was identified by pre-operative chromogalactography, followed by a selective excision of the ductal-lobular unit. In 36 cases (16.1%), however, neither spontaneous nor provocable secretion remained after diagnostic galactography, so that a segment resection was required. In all tissue specimens, the cause of the pathologic secretion was found histologically; most often, it was fibrocystic disease or solitary intraductal papilloma (21.5% each). In 32.3% of the specimens, findings with a prospective significance (papillomatosis, carcinoma in situ or invasive carcinoma) were discovered and further operative treatment was initiated. The colour of the discharge allowed no prediction of the histological findings. In 28.6% (8/28) of the carcinomas, secretion was bilateral. In 46.4% of the specimens containing carcinoma, papillomatosis was also detected; vice versa, papillomatosis was associated with carcinoma in 22.8%. The recurrence rate of 1.6% indicates the efficiency of this method in removing the pathology. The diagnostic value of galactography for the prediction of findings with a prospective significance was considerably reduced by a rate of 37.5% false-negatives; therefore, we have decided to omit diagnostic galactography in our patients. Now, provided extra-mammary causes of the nipple discharge have been excluded and mammography has been inconspicuous, a selective excision of the ductal-lobular unit is performed after preoperative chromogalactography.     

Laryngotracheal resection and reconstruction for subglottic stenosis.

Eighty patients with inflammatory stenoses of the subglottic larynx and upper trachea were treated by single-stage laryngotracheal resection and reconstruction. Fifty stenoses originated from postintubation lesions (endotracheal tubes, tracheostomy, cricothyroidostomy), 7 originated from trauma, 19 were idiopathic, and 4 were miscellaneous. Repair consisted of resection of the anterolateral cricoid arch in all patients, plus resection of posterior laryngeal stenosis where present, with salvage of the posterior cricoid plate, appropriate resection and tailoring of the trachea, and primary anastomosis using a posterior membranous tracheal wall flap to resurface the bared cricoid cartilage in 31 patients. One postoperative death resulted from acute myocardial infarction. Long-term results were excellent in 18 patients, good in 48, satisfactory in 8, and failure in 2. Three additional patients had good results at discharge but were followed up for less than 6 months.     

Therapy of primary fallopian tube cancer--a retrospective study of 30 cases]

Between the years 1968-1988 30 patients with primary carcinoma of the fallopian tube were treated in the Department of Obstetrics and Gynecology of the University of Kiel. In 27 cases the initial treatment consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy. In 3 cases where the patients had undergone surgical treatment in another hospital a second operation for completion was performed. 2 patients received no further treatment after surgery. Postoperative radiotherapy was given to 20 patients and a combined treatment with radiation and polychemotherapy was implemented in 5 cases. Postoperative treatment in 3 patients was poly-chemotherapy alone. The 5-year-survival rate taking all tumor stages and modes of therapy employed into consideration was 36.7%. In analysing the survival rate for small numbers as directly related to postoperative treatment a 5-year-survival rate for radiotherapy of 35% (7/20) and for radiation therapy plus poly-chemotherapy of 40% (2/5) was found. After operative treatment followed by poly-chemotherapy alone one of three patients survived after 5 years.     

Molecular cloning and sequencing of a cDNA for olfactory marker protein.

cDNA clones corresponding to mRNA for rat olfactory marker protein (OMP) were isolated from a cDNA library. The library was constructed from olfactory mucosa poly(A)+ RNA enriched for OMP mRNA and cloned into a pBR322-derived plasmid, pMG5. OMP cDNA clones were detected by using a 17-base oligonucleotide probe that contained all 16 possible sequences coding for a known partial amino acid sequence of rat OMP. The identity of these clones was confirmed by hybrid-selected translation and nucleotide sequencing. The sequence of one clone was determined and contained the complete OMP coding region of 486 nucleotides followed by 1630 nucleotides of the 3' untranslated region. The 3' untranslated region included the polyadenylylation signal 16 nucleotides upstream of the poly(A) tail. No other ATG-initiated open reading frame larger than 20 codons was present in register. RNA blot analysis of olfactory mucosa poly(A)+ RNA using this clone as a probe indicated that the level of OMP mRNA, but not its size, declined significantly within a few days following olfactory bulbectomy. OMP mRNA was not detected in 14 nonolfactory rat tissues. Surprisingly, a small amount of OMP mRNA was observed in olfactory bulb. The presence of OMP mRNA in olfactory bulb was confirmed by in vitro translation and immunoprecipitation. These results suggest either that a previously undescribed population of neurons in the olfactory bulb synthesize OMP or that OMP mRNA is transported to the bulb by axonal transport.
