Post-traumatic spontaneous recurrent hypothermia: a variant of Shapiro's syndrome

A 49-year-old man presented with episodic hypothermia many years after sustaining a contusional brain injury. Brain magnetic resonance imaging demonstrated the destruction of the anterior parts of the corpus callosum without hypothalamic lesions. Nevertheless, delayed hypothalamic dysfunction at the neurotransmitter level is the probable pathophysiological key factor. Clomipramine treatment was beneficial. This case expands the spectrum of Shapiro's syndrome.

目的 提高对食管穿孔和破裂的诊断及处理水平。方法 回顾性分析经外科处理的45例食管穿孔或破裂患的临床资料。结果 本组患经胸部平片、胸腔穿刺、上消化道造影及胃镜确诊。15例为自发性食管破裂，6例为医源性穿孔，5例为创伤性穿孔，10例为食管癌并食管支气管瘘，9例为食管憩室并食管支气管瘘。治疗予以食管修补9例；胸腔引流、空肠造瘘9例(其中1例为食管修补失败后改行此手术)；食管切除胃食管吻合术12例(其中3例为食管修补失败)；胃造瘘术4例；置入食管支架4例；食管支气管瘘切除修补3例；食管瘘口修补并肺叶切除2例；食管胃弓上短路1例，颈部引流2例；放弃治疗3例。治愈25例，好转11例，死亡6例。结论 详细了解病史和进行胸腔穿刺、上消化道造影等检查可帮助诊断。尽早手术闭合瘘口和治疗食管原发病变是治疗的关键。     

Spontaneous reporting of adverse drug reactions in an Italian region: Six years of analysis and observations

Pharmacovigilance started in Italy in 1965, and from 1987 reporting of ADRs has been mandatory. Doctors have to send the filled forms on suspected ADRs to the Local Health Districts which transmit biannually all the reports to the Health Department. In a Northern Italian Region (Veneto) spontaneous reporting of adverse drug reactions (ADRs) has been studied during the period 1988–1993. This Region contributes a substantial percentage of the total Italian reports. The total number of reports was 3700, most of these (54 per cent) coming from GPs. A great variability in the reporting rate among the 36 districts of Veneto Region (range: 0–8.8 per 10,000 inhabitants per year) and an important under-reporting have been evident. Underreporting is also emphasized by the fact that in 1993 the Veneto doctors who sent at least one report were only 2.7 per cent. On the whole about 35 per cent of reports concerned minor reactions caused by drugs which have a well known toxicological profile. Comparison between reports coming from Veneto and the UK in some cases show a similar safety profile (omeprazole and simvastatin), whereas in other cases (e.g. terfenadine, glafenine, fluoxetine) no correspondence can be found. This article reveals the limits of the actual spontaneous reporting in Italy and suggests some possible measures for improving it.     

解脲脲原体与自然流产关系的探讨

采用聚合酶链反应技术对３２例自然流产患者的宫颈粘液及其中２２例清宫组织进行解脲脲原体（ＵＵ）检测，并与３０例人工流产妇女比较。结果表明：自然流产与ＵＵ寄生于宫颈无关（Ｐ＞０．０５），与宫内感染ＵＵ明显相关（Ｐ＜０．０５）。     

615系小鼠自发乳腺癌的发病率及病理形态学观察

100对615系种鼠,常规饲养繁殖,观察33个月(终生),其乳腺癌发病率为5.5%(11例全部发生于经产雌鼠),低于肺腺癌(11%,22例,雌雄各半)而居第二位,故615系小鼠仍属低乳癌品系。对615系小鼠的46例自发乳腺癌进行了病理形态学检查分析:瘤细胞可分为小、中、大三类。组织分型属A型者18例,多由小细胞及少量中细胞构成;属B型者28例,除小细胞外往往可见较多的中细胞甚或主要由大细胞与中细胞构成。B型乳腺癌的分化程度似较A型者为低。转移主要发生于肺部。7例经镜检证实属乳腺癌的肺转移瘤,其原代瘤属A型者1例,属B型者6例。肺转移瘤的组织像与原发瘤基本相同者4例;而细胞变大,呈实心排列,显示分化程度低于原发瘤者3例。     

Paternal and Maternal Smoking Habits before Conception and During the First Trimester: Relation to Spontaneous Abortion

PURPOSE: This study examined the association between maternal smoking before and during the first trimester of pregnancy and spontaneous abortion.

METHODS: We have been conducting a hospital-based case-control study on risk factors for spontaneous abortion in the greater Milan area. We collected information from 782 cases of spontaneous abortions and 1543 controls (women who delivered at term healthy infants).

RESULTS: With respect to never smokers, the odds ratio (OR) were 0.7 (95%, confidence interval (CI), 0.5–1.0) for women who quit smoking and 1.3 (95% CI, 1.0–1.6) for those who continued during pregnancy. Women who smoked more than 10 cigarettes/day in the first trimester were at increased risk of miscarriage, with an OR of 1.4 (95% CI, 1.0–2.1). No relationship was evident between the number of cigarettes smoked before conception and the risk of abortion. Likewise, no association emerged between paternal smoking and miscarriage. Moreover, no significant interaction or modification effect was obtained when strata of age and other major characteristics were investigated.

CONCLUSIONS: The risk of abortion associated with cigarette smoking during the first trimester of pregnancy was measurable and noticeable in this population, and accounted for 9% (95% CI, 6–13%) of all cases. The increased risk of spontaneous abortion in women smoking during pregnancy is a further reason to encourage pregnant women to quit.     

Spontaneous ovarian hyperstimulation mimicking an ovarian tumour

Ovarian hyperstimulation syndrome in a spontaneous singletonpregnancy is exceedingly rare. We report a case of ovarian hyperstimulationpresenting as bilateral ovarian masses in association with spontaneouspregnancy, occurring in a woman with disturbed liver function.A possible mechanism is discussed.     

Pharmacological properties of a lyophilizate from Galeopsis ladanum on the central nervous system of rodents

The influence of a fraction obtained from Galeopsis ladanum L. on the central nervous system of rodents was examined. The results of these investigations show that the fraction impeded CNS activity. It is practically nontoxic and at a dose of 2000 mg/kg i.p. it does not have a soporific influence on mice. It reduces considerably the spontaneous locomotor activity of mice as well as the locomotor activity of mice stimulated by caffeine, but did not influence the locomotor activity induced by amphetamine. The extract did not exhibit a synergetic effect with barbiturates. The results suggest that the pharmacological activity of the extract resembled the activity of drugs which generally depress the CNS, being on the border between ataractic and sedative drugs.     

Molecular interactions during pregnancy: Association between mannan binding protein deficiency and recurrent miscarriage

The distribution of mannan binding protein (MBP) in blood donorsera was determined by enzyme-linked immunosorbent assay toestablish normal concentrations. Abnormally low MBP concentrationswere found in 16% (21 out of 135) of female partners and 14%(15 out of 108) of male partners of couples experiencing recurrentmiscarriage, compared with <5% of obstetrically normal controls(P < 0.005). This relationship was even stronger (9.5 versus1.0%) and more significant (P < 0.002) when only subjectspresumed to be homozygous for the mutant allele responsiblefor MBP deficiency were considered. By immunohistochemistry,MBP could be demonstrated in first trimester placenta. We suggestthat low concentrations of MBP within the feto-placental unitincrease susceptibility to fetal loss, possibly via an infection-inducedplacental cytokine imbalance.     

以心跳骤停为首发症状的蛛网膜下腔出血共同特征研究

<正>心跳骤停（cardiac arrest,CA）和蛛网膜下腔出血（subarachnoid hemorrhage,SAH）均是急诊科常见的急危重症,CA可见于多种疾病的各个阶段,复苏成功率不高,甚至造成CA的病因不甚明确。SAH典型表现为剧烈头痛、呕吐、脑膜刺激征,诊断并不困难。而以CA为首发症状的SAH,由于心肺复苏无法常规进行头颅CT检查,给诊断增加了困难。本文通过对16例以CA为首发症状的SAH患者进行回顾性研究,来提高SAH-CA的快速病因诊断,避免漏诊误诊。
