Bowel visualization during indium-111-labelled diethylene triamine penta-acetic acid cisternography due to massive cerebrospinal fluid leak

We report a case of massive cerebrospinal fluid (CSF) leakage where the tracer injected intra-thecally for radionuclide cisternography was later visualized in the bowel as well as the nasopharynx. We discuss the potential implications of this finding in patients with CSF leaks. A brief review of the diagnosis of CSF leaks is included.     

Endometriosis: Endometriosis and infertility: raised iron concentration in the peritoneal fluid and its effect on the acrosome reaction

Endometriosis and infertility are commonly associated. Thisstudy investigated the role of accelerated lipid peroxidationof spermatozoa by the peritoneal fluid of patients with endometriosisas a cause for this association. It proposes that the increasediron concentration present in the fluid of these patients actsas a catalyst for the process. Peritoneal fluid from 25 patientswith endometriosis and 25 matched controls was obtained at laparoscopy.Spermatozoa were incubated in the fluid from both groups andthe subsequent acrosome reaction rates analysed. The relationshipbetween these results and iron concentration in the fluid wasexamined. A significant decrease in the acrosome reaction ratewas seen in the endometriotic group(P = 0.034). Overall, a decreasein the acrosome reaction rate was associated with an increasediron concentration in the fluid(18 of the 25 pairs). In milddisease, (six of 11 pairs), the relationship was not as markedas that in severe disease (12 of 14 pairs). These results suggestthat the peritoneal fluid in patients with endometriosis hasa detrimental action on the acrosome reaction of spermatozoain vitro.     

Acute volaemic changes modify the gastroduodenal resistance to the flow of saline in anaesthetized dogs

The effect of acute and sequential volaemic changes on the gastroduodenal flow of saline was assessed in 23 anaesthetized dogs following two different experimental protocols. Hypervolaemia, by i. v. infusion of saline, induced a gradual decrease on gastroduodenal flow which amounted to 76% below control values (P < 0.001) when volaemic expansion attained 5% of body weight. This effect was volume dependent (17% increase on gastroduodenal flow per volume of infused saline equivalent to 0.5% of body weight, P < 0.001), lasted for at least 90 minutes after infusion was completed and was also obtained by expanding previously bled animals. Hypovolaemia due to bleeding was followed by an increase on gastroduodenal flow of about 88% above control values (P < 0.05) when haemorrhage was equal to 3% of body weight. This effect was also volume dependent (23 % increase on gastroduodenal flow per volume of blood shed equivalent to a 0.5% of body weight, P < 0.01) and was reversed after blood volume was restored. These modifications in the resistance of the gastroduodenal segment to the flow of liquid due to acute volaemic changes suggest that the extracellular fluid volume modulates the contractile activity of the gastroduodenal portion of the gut possibly to set a gastroduodenal handling of liquid adequate to cope with volaemic imbalances.     

龈沟液ALP活性与牙周病的关系

对牙周健康者和龈炎、牙周炎患者２５人共１３０个牙位的龈沟液（ＧＣＦ）中硷性磷酸酶（ＡＬＰ）活性进行了检测。ＧＣＰ－ＡＬＰ活性（ｕ／ｕＬ或ｕ／牙）在炎症牙位和健康牙位间有显著差别，与牙龈指数（ＧＩ）和附着丧失（ＡＬ）呈正相关性。炎症牙位经牙周综合治疗６周后，其ＧＣＦ－ＡＬＰ活性显著降低。说明ＧＣＰ－ＡＬＰ水平能反映出牙周组织炎症的进展情况。     

Subhepatic collections complicating laparoscopic cholecystectomy: Percutaneous management

Ten patients with subhepatic fluid collections complicating laparoscopic Cholecystectomy were successfully treated by interventional radiological procedures. The series included five abscesses, three hematomas, one biloma, and one serous collection. Abdominal pain or fever developed from 3 to 21 days after the laparoscopic intervention. All patients were asymptomatic 72 h after percutaneous drainage and there were no complications related to the procedure. Subhepatic fluid accumulations are common findings after laparoscopic cholecystectomies and have been considered an unreliable indicator of infection or other postoperative complications. However, the significance of these collections should not be underestimated in symptomatic patients. In such cases we propose diagnostic aspiration and drainage, when necessary, to safely and promptly establish the precise diagnosis and treatment. More serious complications can be avoided by early percutaneous intervention.     

鼻内窥镜诊治脑脊液漏的临床研究

目的 探讨鼻内窥镜手术治疗脑脊液鼻漏临床相关因素。方法 对17例（19漏）内窥镜下修补脑脊液鼻漏患者的临床资料作回顾性分析。结果 脑脊液鼻漏17例中，外伤性15例，自发性2例，内窥镜下瘘口修补术一次性治愈15例，成功率88.2%，失败2例，再次修补成功，其中1例颅内高压术后腰穿持续引流减压。结论 内窥镜手术修补脑脊液鼻漏准确、微创；冠位CT薄层扫描对术前瘘口解剖定位有重要意义；影响手术效果的因素与修补材料的固定有关，与修补材料本身无明显关系；术后适当腰穿引流对于临床提示颅内压高、修补区薄弱病例仍需采用。

Diffusion‐Weighted MRI in Creutzfeldt‐Jakob Disease: A Better Diagnostic Marker Than CSF Protein 14‐3‐3?

Two middle-aged patients presented with rapidly progressive dementia and ataxia, nonspecific electroencephalography findings, and negative cerebrospinal fluid (CSF) protein 14-3-3. Both patients underwent brain magnetic resonance imaging (MRI) scans that demonstrated abnormalities on diffusion-weighted imaging (DWI) sequences, and both were later confirmed to have Creutzfeldt-Jakob disease. (CJD) by tissue examination. Because a recent position paper from the American Academy of Neurology characterized CSF protein 14-3-3 as a gold standard for clinically diagnosing CJD, the authors reviewed studies of CJD in which DWI-MRI imaging and CSF protein 14-3-3 studies were both performed. Among 19 reported cases of CJD with DWI-MRI lesions, CSF protein 14-3-3 was negative in 6 cases and positive in 2 others. The authors' findings suggest that multifocal cortical and subcortical hyperintensities confined to gray matter regions in DWI-MRI may be a more useful noninvasive diagnostic marker for CJD than CSF protein 14-3-3. These observations provide a compelling rationale for a prospective comparative study.     

Serum and Cerebrospinal Fluid Vitamin B12 Levels in Demented Patients with CH3—B12 Treatment—Preliminary Study—

Abstract: The vitamin B12 (VB12) parameter was studied in the serum and cerebrospinal fluid (CSF) of 14 demented patients. Eleven of these patients were in a state of dementia of the degenerative type such as Alzheimer's disease, senile dementia and Pick's disease. The serum VB12 concentration in all the patients was within normal limits, I.e. 500–1,300 pg/ml. There was no significant difference between the CSF-VBl2 levels and the severity of dementia. The serum and CSF-VB12 levels of the demented patients did not show any significant elevation after the oral administration of CH3–Bl2, 2 mg per day. On the other hand, there was a marked elevation of both the serum and CSF-VB12 after an oral medication (2 mg per day) plus intramuscular administrations (500 μg per day). These results confirm that the intramuscular administration of CH3–B12 is an effective way to get a higher value of the serum and CSF-VB12 levels.
