Background: Anaesthesia for caesarean section (CS) in women with eclampsia is a major clinical challenge, and there are limited data concerning the rationale for the choice of technique, and short-term outcomes. A retrospective audit was performed on practice at a tertiary referral centre in Cape Town. Methods: The primary outcome of the audit was the proportion of patients with eclampsia receiving either spinal anaesthesia (SA) or general anaesthesia (GA) for CS, and an assessment of the rationale for the choice of method. In addition, short-term maternal and neonatal outcomes were recorded. Results: There were 11 exclusions in 100 patient records screened, therefore 89 were analysed. Seven/89 (7.9%) patients received SA and 82/89 (92.1%) GA. Overall, 63/89 (70.8%) patients had a preoperative GCS < 14, and 26/89 (29.2%) ≥ 14. Seven/26 patients with GCS ≥ 14 had SA; the remaining 19/26 received GA. GA was performed because there was no platelet count available in three, pulmonary oedema in two, difficult airway due to a bitten tongue in two, fetal bradycardia in two, HELLP syndrome in one, renal failure in one, and patient refusal in one patient. In seven women, there was no clear reason for GA. Median (IQR) Apgar scores at 1 minute in SA patients (8 [8–9]) were higher than those in GA patients with GCS ≥ 14 (5 [3–6]) and < 14 (4 [2–6]), p = .008 and .001 respectively. At five minutes, neonates of SA patients had median scores of 10 [9–10], compared with 8 [7–8] in those of GA patients with GCS ≥ 14, and 8 [7–9] in those with GCS < 14, p = .007 and .019 respectively. There were two stillbirths and two neonatal deaths in the GA group. Patients with GCS ≥ 14 receiving GA required mechanical ventilation for 0 [0–1] days, and those with GCS < 14 were ventilated for 1 [1–2] days. No patients receiving SA required postoperative ventilation, compared with 5/19 (26.3%) patients with GCS ≥ 14 who received GA. Seven/63 patients with GCS < 14 had cerebral oedema, and two had a cerebral infarct. There were two maternal deaths. Conclusions: The small percentage of women with eclampsia who received SA for CS, experienced good maternal and fetal outcomes, and more patients could have safely received SA. Larger prospective audits in high- and low-resource environments are required to establish factors influencing the context-sensitive choice of method of anaesthesia, and risk versus benefit of GA versus SA for CS in women with eclampsia.

Implicit And Explicit

This study is an examination of the effect of the different degrees of explicitness of written corrective feedback (WCF) on implicit and explicit knowledge of the target structure (past simple tense) in the short term and long term. There were four experimental groups including a control group, in this quasi-experimental study which received different degrees of explicit WCF. This study sought to investigate whether or not written corrective feedback could also be effective in targeting the problematic error category in the texts of FL writers. Past simple test was known as the problematic structure based on the result of the pre-test, though their level of proficiency was intermediate. It was found that both metalinguistic and direct WCF could affect the participants’ explicit knowledge of the past simple tense in the short term and long term; the indirect WCF on the other hand, could only affect the explicit knowledge in the short term and the reformulation was the only kind of WCF that did not have any effect on the explicit knowledge of the past simple tense. Moreover, all the experimental groups’ implicit knowledge improved in the short term; however, this improvement was sustained in the long term for the metalinguistic and indirect groups only. Journal of NELTA, Vol. 21, No. 1-2, 2016, Page:74-85

Use Of Knowledge

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Pulsatile Perfusion

Short term experimental and clinical preservation of kidneys is presently best accomplished by hypothermic continuous pulsatile perfusion with cryoprecipitated and millipore filtered plasma. This study was undertaken to observe ultrastructural changes occurring during 24-hour preservation using the above mentioned method.A kidney was removed through a midline incision from healthy mongrel dogs under pentobarbital anesthesia. The kidneys were flushed immediately after removal with chilled electrolyte solution and placed on a LI-400 preservation system and perfused at 8-10°C. Serial kidney biopsies were obtained at 0-½-1-2-4-8-16 and 24 hours of preservation. All biopsies were prepared for electron microscopy. At the end of the preservation period the kidneys were autografted.

Polychlorinated biphenyls (PCBs) are a ubiquitous class of environmental pollutants with toxic and hepatocellular effects, including accumulation of fat, proliferated smooth endoplasmic recticulum (SER), and concentric membrane arrays (CMAs) (1-3). The CMAs appear to be a membrane storage and degeneration organelle composed of a large number of concentric membrane layers usually surrounding one or more lipid droplets often with internalized membrane fragments (3). The present study documents liver alteration after a short term single dose exposure to PCBs with high chlorine content, and correlates them with reported animal weights and central nervous system (CNS) measures. In the brain PCB congeners were concentrated in particular regions (4) while catecholamine concentrations were decreased (4-6). Urinary levels of homovanillic acid a dopamine metabolite were evaluated (7).Wistar rats were gavaged with corn oil (6 controls), or with a 1:1 mixture of Aroclor 1254 and 1260 in corn oil at 500 or 1000 mg total PCB/kg (6 at each level).

Toxic Responses

Introduction. Experimental induction of altered histology by chemical toxins is of particular importance if its outcome resembles histopathological phenomena. Hepatotoxic drugs and chemicals are agents that can be converted by the liver into various metabolites which consequently evoke toxic responses. Very often, these drugs are intentionally administered to resolve an illness unrelated to liver function. Because of hepatic detoxification, the resulting metabolites are suggested to be integrated into the macromolecular processes of liver function and cause an array of cellular and tissue alterations, such as increased cytoplasmic lysis, centrilobular and localized necroses, chronic inflammation and “foam cell” proliferation of the hepatic sinusoids (1-4).Most experimentally drug-induced toxicity studies have concentrated primarily on the hepatic response, frequently overlooking other physiological phenomena which are directly related to liver function. Categorically, many studies have been short-term effect investigations which seldom have followed up the complications to other tissues and organs when the liver has failed to function normally.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.
