Abstract
A woman aged 67 years attended the emergency department with acute abdominal and back pain of 1-day duration with associated vomiting. The patient had multiorgan failure. Resuscitation was started with intravenous fluids and vasopressors. An abdominal CT scan was completed which confirmed the diagnosis of acute gastric volvulus. The patient was successfully resuscitated from a cardiorespiratory arrest during transfer to the operating theatre. The patient subsequently underwent a total gastrectomy with stapling of the oesophageal and duodenal stumps. The abdomen was packed and left open as a laparostomy with a planned relook 48 hours later was to be performed. Unfortunately, the patient continued to deteriorate postoperatively in the intensive care unit despite maximum organ support for multiorgan failure. A decision was made to withdraw treatment and the patient died 10 hours postoperative. This case illustrates the presentation of acute gastric volvulus at a late stage and the high mortality rate associated with it.

Abstract
BACKGROUND The purpose of this study was to investigate whether there is a risk of epidural catheter damage during the advancement of the spinal needle through an epidural needle in clinical use. METHODS A total of 100 catheters (50 from CSE kits with a pencil-point type spinal needle and 50 from CSE kits with a Quincke type spinal needle) which had been used for routine CSE blocks were microscopically examined for any defects within the first 150 mm of the catheter. Additionally 10 unused new catheters were investigated. RESULTS Among 10 unused catheters 5 slight scratches were found, 92 out of 100 used catheters did not show any signs of use or scratches, 7 showed some signs of use and longitudinal scratches whereas another 1 showed a moderate scratch of less than 25% of the wall thickness. There was no difference in the prevalence of scratches between the CSE kits with pencil-point type spinal needles compared to those with Quincke-type spinal needles. CONCLUSION The CSE technique with either pencil-point type or Quincke-type spinal needles for subarachnoidal punctures was safe and showed no relevant epidural catheter damage.

Abstract
BACKGROUND AND AIMS Pancreatic cancer is characterized by a constant deterioration in quality of life, excruciating pain and progressive cachexia. The aim of this study was to compare the effectiveness of two invasive methods of pain treatment in these patients: neurolytic coeliac plexus block (NCPB) and videothoracoscopic splanchnicectomy (VSPL) to a conservatively treated control group concerning pain, quality of life and opiates' consumption. PATIENTS AND METHODS Fifty nine patients suffering from pain due to inoperable pancreatic cancer were treated invasively with NCPB (N=35) or VSPL (N=24) in two non-randomised, prospective, case-controlled protocols. Intensity of pain (VAS-pain), quality of life (FACIT and QLQ C30) and opioid intake were compared between the groups and to a control group of patients treated conservatively before the procedure and after 2 and 8 weeks of follow-up. The analysis was performed retrospectively using meta-analysis statistics. RESULTS Both methods of invasive pain treatment resulted in significant reduction of pain (VSPL effect size=11.27, NCPB effect size=7.29) and fatigue (effect sizes, respectively, 1.23 and 3.37). NCPB improved also significantly physical, emotional and social well-being (effect sizes, respectively, 2.37, 4.13 and 7.51) which was not observed after VSPL. No influence on ailments characteristic for the disease was demonstrated. Mean daily opioid consumption was significantly decreased after both procedures. There was no perioperative mortality and no major morbidity. CONCLUSION Both NCPB and VSPL provide significant reduction of pain and improvement of quality of life in inoperable pancreatic cancer patients. They present rather similar efficacy, but lower invasiveness of NCPB, in combination with its more positive effect on quality of life, pre-disposes it as being the preferred method.

Abstract
Ten candidate countries are expected to join EU in 2004. In the field of plant protection product (PPP) regulation, at EU level, acceding states will have roles in evaluation for listing of active substances in Annex I of Directive 91/414/EEC and ensuring that at national level, regulatory procedures comply with the acquis communautaire. This paper briefly outlines the impact of the acquis on the roles of Member States at both EU and national levels. It then briefly explains the current Czech Republic regulatory system as operated by the State Phytosanitary Administration and the National Institute of Public Health and the steps that the Czech Republic will have to take to implement the acquis requirements. Finally it makes an assessment as to how successful implementation of the acquis will prove beneficial to the acceding states and the parties which rely on the service that the regulatory authorities provide (i.e. the public, farmers and growers and the agrochemical industry).

Abstract
BACKGROUND Cholecystectomy is a surgical gold-standard procedure for gallbladder diseases, among which gallstones are the most frequent. Despite the introduction of minimally invasive surgery and broad access to ultrasound examination there is a group of patients in whom the surgery ailments persist. Those vague ailments can be perceived from a psychological point of view as somatization or even somatoform disorders. METHODS The aim of the study, designed as a case-control study, was to evaluate psychological characteristics that may accompany the incidence of so-called post-cholecystectomy pain syndrome (PCPS). The study focused on 367 patients treated for gallstones in the Dept. of General, Gastroenterological and Endocrinological Surgery, Medical University of Gdańsk, Poland. At about a year after the operation, the patients received a questionnaire that included a structured interview and psychological assessment of social support and rumination. Those who revealed symptoms of PCPS were invited to the department for further medical and psychological evaluations. Psychosocial scores of PCPS and non-PCPS patients were compared. RESULTS The PCPS patients did not present any dysfunction at the physical examination or in gastroduodenoscopy or sonography. However, they differed from the remaining. asymptomatic group in terms of lacking social support, as well as increased rumination. CONCLUSION It is concluded that psychological variables may play an important role in the onset of subjective symptoms in at least a subgroup of the PCPS patients as a form of somatization. Psychological supportive and explanatory activities (cognitive and behavioural approach) may provide sufficient help.

Abstract
The preoperative detection of accessory spleens (AS) is essential in ITP patients. The aim of this study was to evaluate the reasons of failure and long-term results of laparoscopic splenectomy (LS) in patients with idiopathic thrombocytopenic purpura (ITP). Thirty-four ITP patients (27 females and 7 males) underwent LS between June 1998 and January 2001. Computed Tomography (CT) and sonography (US) were performed preoperatively to evaluate the size of the spleen and to detect the presence of possible accessory spleens which were found in two cases. AS were seen during laparoscopy in three cases. During follow-up (median time = 23 months), in three patients a low platelet count was seen after 5 months, 1.5 and 1.8 years pop. In all these cases scintigraphy was performed, which revealed in one case the residual accessory spleen. In the two other patients, inspite of thrombocytopenia no residual spleens were found. The authors conclude that laparoscopic splenectomy is a safe and effective procedure in patients with ITP. The problem of accessory spleens can be managed by careful videoscopic examination of the abdominal cavity during splenectomy. The use of the preoperative imaging techniques for detection of accessory spleens is limited by the insufficient sensitivity of the examination.

Abstract
AIM The authors evaluate the effectiveness of videoscopic adrenalectomy (VA) for a variety of endocrine disorders. METHODS One hundred and ten consecutive videoscopic adrenalectomies performed from October 1995 till December 2000 were reviewed and followed up for adequacy of surgical treatment in 2 surgical departments. There were 79 females and 31 males included in the study. The mean age was 48.0 years (range 23-71 years). Indications for the operations were: phaeochromocytomas (n=5), aldosterone-producing adenomas (n=19), cortisol-producing adenomas (n=10), Cushing's disease (n=3) and non-secreting tumours (n=72). RESULTS There was no mortality and no morbidity both intraoperatively and in the postoperative course. In 8 cases conversion to open surgery was instituted - in 4 cases due to an unintended lesion of pertioneum without damage to the intraperitoneal organs. Mean operative time was 156 min (range 52-280 min), and estimated blood loss was 73 ml (range 20-300 ml). The average length of hospital stay was 2.9 days (range 2-7 days). None of the patients revealed either recurrence of hormonal hypersecretion or tumour mass in imaging studies during the follow-up period (range 1-34 months). CONCLUSION 1. VA is recommended in patients with hormonally active tumours and in patients with benign adrenal masses of a diameter up to 6 cm. 2. VA is a safe and feasible procedure if performed by a team experienced in endocrine and endoscopic surgery. 3. VA is a procedure better than open adrenalectomy in management of small, non-malignant tumours because of the reduction of operative trauma.

Abstract
Chronic administration of estradiol leads to generation of estrogen-dependent renal cancer in male Syrian hamsters within 9-12 months. The pathogenesis of this tumour is associated with oxygen free radicals, however, it is still not clear which metabolic pathway of estrogens is responsible for the generation of the radicals, and which part of the cell is mostly affected by it. The paper presents an experiment in which the protein oxidation measured by carbonyl groups level in 9-month estrogenization scheme. The level of carbonyl groups was significantly elevated starting from the 1st month of estrogenization until the 9th. The weight of the kidneys reflecting possible tumuorigenesis was also significantly increased in estrogenized group starting at the 2nd month of the experiment. The weight of the testes, a sign of adequate estrogenicity, was decreased dramatically in the estrogenized group from the first to the last month of experiment. The results suggest that the kidney of estrogenized male Syrian hamster suffers from oxidative stress affecting proteins.

Abstract
Clinically silent adrenal masses (incidentaloma) are incidentally discovered lesions, when noninvasive imaging methods (USG, CT, MRI) are performed for reasons other than known or suspected adrenal disease. Most studies report on a prevalence of adrenal incidentaloma range between 1% and 10% in radiological series. Between 1994 and 1999 we observed in our Department 57 patients with incidentalomas of adrenal glands. After endocrinological evaluation silent Cushing's syndrome was found in 2 cases (3.5%). Fifty two patients were qualified for surgery. Adrenocortical adenoma was diagnosed in 73.1%; adrenocortical carcinoma in 7.7%; pheochromocytoma in 7.7% and less frequent adrenal lesions in 11.5%. All adrenal carcinomas and malignant pheochromocytomas (11.5%) were found in tumors with diameter over 4 cm.

Abstract
UNLABELLED The aim of the study is presentation of operative technique and early results of laparoscopic splenectomy in 15 cases of idiopathic thrombocytopenic purpura (ITP) patients resistant to typical steroid therapy. There were 7 women and 8 men in age 16-58 years (mean 32.6 years). Preoperative investigations revealed accessory spleens in two patients. Platelets count at the time of qualifying patients to splenectomy varied from 7-35 g/L and after preoperative treatment (prednisone 1 mg/kg--6 patients, methylprednisone 25 mg/kg--5 patients, immunoglobulins 2.0/kg--2 patients, immunoglobulins and methylprednisone--2 patients) varied from 36-205 g/L. Splenic length was from 8-17 cm. The lateral approach and 4-5 ports were utilized in all cases. Pneumoperitoneum with value of 12-14 mmHg of carbon dioxide was created using an open technique. First step of the procedure was to free spleno-colic ligament, then spleno-reno attachment. In all cases the hilus artery, vein and short gastric vessels were clipped and divided by Endo GIA stapler 30 or 60 mm and clips. Spleens were removed from the abdomen cavity in the plastic bag after manual/forceps crushing inside the bag. Intraoperative bleeding occurred in 2 patients (20%). Blood loss was about 800 and 1000 ml respectively. The mean operative time was 170 min (140-300 min). Spleen weight was 210 g average. In 3 cases conversion to open approach was needed because of injury of splenic vessels (2 pts.) and difficulty in removing spleen--in 1 patient. Post operative course was uneventful in every 10 patients. Mean hospital stay was 5.8 days. Increase in platelet count was observed in 14 patients on the second postoperative day to 60-291 g/L. One patient did not response as expected. No early postoperative complications were observed. CONCLUSION Laparoscopic splenectomy may be considered as a safe and feasible procedure in selected patients with ITP without long-term improvement after typical conservative treatment.

Abstract
The aim of this study was to evaluate the influence of different types of anesthesia upon the intra- and postoperative body temperature in osteogenesis imperfecta patients. The development of an intraoperative hyperpyrexia of unknown origin is a typical phenomenon in patients with osteogenesis imperfecta. Body temperatures of up to 40 degrees C are known to complicate the operation. Therefore, in a retrospective study, the pre-, intra- and postoperative body temperature curves of 45 operations under different anaesthesias were measured. Group A underwent a common balanced anaesthesia with the volatile anaesthetic Enfluran in combination with Fentanyl, while group B was operated on under total intravenous anaesthesia (TIVA) with Propofol and Alfentanil. The preoperative temperatures were not different in the two groups. The intraoperative curves showed a constant body core temperature or even an increase under Enfluran, while the temperature always decreased under TIVA. This could be confirmed by intraindividual studies in 5 patients.

Abstract
The purpose of this study was to verify whether injection of tert-butyl hydroperoxide (Bu(t)OOH, a well-known prooxidant agent) into the bile-pancreatic duct can induce acute pancreatitis. A rapid blockade of the secretion was observed in the majority of the animals after 3 hours of observation. After 6 hours, the secretion reached a very low level, significantly different compared with controls. In groups of rats injected with Bu(t)OOH, pancreatic weight gain was observed compared with the rats injected with physiologic saline. Histology of pancreata removed 3 hours after injection of Bu(t)OOH showed acinar cell vacuolization, interstitial edema, focal necrosis of pancreatic acini, fat-tissue necrosis, and leukocyte infiltration of the organ. These changes were considerably greater after the 6-hour observation period. Electron-microscopic inspection revealed profound morphologic changes 3 hours after Bu(t)OOH injection. The control rats receiving physiologic saline alone had well-preserved pancreatic tissue structure. In conclusion, injection of the prooxidant agent, tert-butyl hydroperoxide, into common bile-pancreatic duct induces acute necrotizing pancreatitis, which indicates the crucial role of free radical reactions in pathogenesis of this disease.

Abstract
We are reporting the case of a parapubic hernia that occurred after radical prostatectomy. This kind of the hernia is caused by the weakening of the attachments of rectus muscles to the pubic bone. Because of its location, it may be misdiagnosed as a far more common direct inguinal hernia. A laparoscopic approach made it possible to precisely diagnose and repair the defect in the abdominal wall.

Abstract
From April to November 1998 eleven patients (8 female and 3 male, mean age 48.5; range 23-69) with adrenal gland tumor underwent laparoscopic adrenalectomy from the lateral retroperitoneal approach. Authors report their primary experience; introduce their own material and describe the operative technique of laparoscopic adrenalectomy from lateral retroperitoneal approach. Besides one case of Conn syndrome, all tumors were hormonally non-active. In 10 patients the adrenal masses were incidentally discovered during such imaging examination as abdominal ultrasonography and computed tomography. All tumors were benign in postoperative histopathological examination. The localization was unilateral and suprarenal in all cases (7 right, 4 left). Both operation and postoperative course in all patients were uncomplicated. One conversion to "open" procedure had been performed due to laparoscopic equipment damage.

Abstract
In this paper we described a case of 56 old patient with history of joint disease. We diagnosed chondrocalcinosis with hypomagnesemia. The patient was treated for gout during last 13 years. The frequency of chondrocalcinosis is estimated about 10% in patients after 50 years of age, but it is very rare diagnosed. A correct diagnosis is possible on the basis of simple tests and it allows to avoid the drugs which are not effective in this disease.

Abstract
We present laparoscopic method of treatment of parapubic hernia that may occur after radical prostatectomy performed due to prostatic cancer. This kind of hernia is closely related to the weakening of the rectus muscle of abdomen insertions to the pubic bone that takes place during the operations using lower midline incision in order to reach organs in the small pelvis. Because of its localization it may be misdiagnosed as a commoner direct inquinal hernia. In this case the traditional anterior approach would not be curative. Using laparoscopy as it is suggested by authors will make the proper diagnosis much more easy and thus will enable effective treatment of the patient.

Abstract
Squamous cell carcinomas of the head and neck have been found to show a high expression of the receptor for epidermal growth factor (EGF). This overexpression of the receptor has been associated with malignant transformation of cells, although there is still debate as to what extent this receptor takes part in the proliferation of malignant cells and which function it fulfills. The factors which determine receptor-ligand interaction are also not clearly defined. That the extracellular domain of the EGF receptor carries carbohydrate or sialoglycan structures might be important for function of the receptor. Since tumor specific enzymes can possibly alter such structures, it was the aim of our study to investigate the role of these structures on the EGF receptor during the proliferation of head and neck carcinomas. We used the human laryngeal squamous carcinoma cell line HLaC 79 and altered, for the first time, specific glycan structures with sialidase alpha-2,3 and alpha-2,6, causing desialylation. Changes were also produced by endo-beta-galactosidase and sialyltransferase. Findings were monitored by labeling with bromo-deoxyuridine. To determine receptor affinity, 125I-labeled EGF was employed. Results showed that both cell proliferation and receptor affinity depended on the level of sialylation of the receptor carbohydrate side chains. Desialylation led to a statistically significant reduction of tumor cell proliferation to 65 +/- 33% (P < 0.01), while receptor affinity decreased to 70 +/- 26% (P < 0.01). The importance of EGF receptor for the proliferation of malignant cells seems to depend on the level of sialylation of glycan structures on receptor protein. A release of enzymes by tumor cells may then produce auto-control of tumor proliferation on its own.

Abstract
Respiratory infection is a major cause of morbidity after general anaesthesia. Impairment of respiratory ciliary beat frequency (CBF) by different stress factors causes a decrease in mucus transport rate (MTR). We have tested the effect of different concentrations of oxygen on CBF of human respiratory epithelium in a prospective, randomized, in vitro study. Samples of superficial mucosa of the inferior nasal turbinates of 20 non-smoking healthy volunteers were harvested and exposed to three different oxygen environments (group I = 21% oxygen, group II = 60% oxygen and group III = 95% oxygen) for 2 h. In 50% of the samples, exposure time was prolonged. At 30, 60, 90, 120 and 240 min, light microscopic images of cilia activity were videotaped and CBF was later assessed in slow motion. Compared with baseline, group I showed no difference in CBF throughout the study. CBF was increased in group II from mean 9.7 (SD 0.4) to 11.2 (0.4) Hz (16%, P < 0.001) and in group III from 9.5 (0.6) to 12.1 (0.5) Hz (28%, P < 0.001) at 120 min. After 240 min of exposure to 95% oxygen, the CBF trend in group III was reduced to 11.8 (0.6) Hz but still remained above baseline. We conclude that oxygen appeared to have a dose- and time-dependent accelerating effect on CBF. Prolonged exposure to high oxygen concentrations reversed this trend. Direct oxygen toxicity ("oxygen stress") is a possible explanation for this effect. These changes may result in impaired MTR.

Abstract
UNLABELLED A potential risk of the laryngeal mask airway (LMA) is an incomplete mask seal causing gastric insufflation or oropharyngeal air leakage. The objective of the present study was to assess the incidence of LMA malpositions by fiberoptic laryngoscopy, and to determine their influence on gastric insufflation and oropharyngeal air leakage. One hundred eight patients were studied after the induction of anesthesia, before any surgical manipulations. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 40 cm H2O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relation to the laryngeal entrance was verified using a flexible bronchoscope. The overall incidence of LMA malpositions was 40% (43 of 108). Gastric air insufflation occurred in 19% (21 of 108), and in 90% (19 of 21) of these patients, the LMA was malpositioned. Oropharyngeal air leakage occurred in 42%, and was independent of LMA position. We conclude that clinically unrecognized LMA malposition is a significant risk factor for gastric air insufflation. IMPLICATIONS Routine placement of laryngeal mask airways does not require laryngoscopy. In our study, fiberoptic verification of mask position revealed suboptimal placement in 40% of cases. Such malpositioning considerably increased the risk of gastric air insufflation.

Abstract
Epidural anaesthesia is extremely useful in providing postoperative analgesia for children after surgery of the lower body. Although results on early pharmacokinetics in children have previously been reported, no data are available on the long-term effects of epidural anaesthesia. The aim of this investigation was the assessment of plasma bupivacaine levels in children with continuous epidural anaesthesia in the postoperative period. A catheter with an outer diameter of 0.63 mm was inserted through a 19G Tuohy cannula into the epidural space. A maximum dose of 0.4 mg/kg/h bupivacaine was administered for continuous epidural infusion. Careful monitoring was performed to detect early signs of local anaesthetic intoxication. Two milliliters of blood were obtained in each patient per day and nepholometric serum measurement were performed to determine alpha 1-acid glycoprotein and albumin levels. Bupivacaine plasma concentrations were assessed according to the method described by Sattler et al. [25]. Ten children were included in the investigation. The measured albumin and alpha 1-acid glycoprotein concentrations were within the range described by other investigators. At the onset of pain therapy maximum levels of 0.5 microgram/ml were recorded after a loading dose of bupivacaine and levels of up to 2.2 micrograms/ml were achieved following continuous infusion. There were no neurologic complications or signs of local anesthetic intoxication. In conclusion our results show that a dose of up to 0.4 mg/kg/h bupivacaine during continuous epidural infusion is not associated with toxic complications. Careful monitoring of the children by experienced staff is mandatory.

Abstract
This study aimed to investigate the protein peroxidation process in cerulein induced acute pancreatitis. Eighteen rats were divided into three equal groups: group 1 acted as control rats had intraperitoneal injection of 0.9% NaCl, in group 2 and 3 rats had injection of cerulein 40 micrograms kg-1 for 3 or 6h of induction period respectively. Protein carbonyls which reflect peroxidative damage were found to be increased after 3h up to 2.53 +/- 0.49 comparing to 1.05 +/- 0.17 in control group and returned to control level 0.95 +/- 0.04 after 6h. These data suggest that during acute pancreatitis free radicals may play an essential role in protein damage. Decrease in protein carbonyls content after 6h suggests an elevated proteolysis of oxidatively damaged proteins.

Abstract
STUDY DESIGN A case report of spinal extradural angiolipoma, a rare tumor that can cause spinal cord compression, is presented with a complete review of the literature related to this disorder. OBJECTIVES To discuss venous thrombosis involving the angiolipoma in the development of subacute paraparesis. SUMMARY OF BACKGROUND DATA This case shows that venous thrombosis of a spinal angiolipoma can precipitate the subacute onset of paraparesis. METHODS Medical history, physical findings, and the results of imaging and histopathologic studies were analyzed to elucidate the pathogenesis of the patient's subacute onset of paraparesis. A bilateral T3-T7 laminectomy was performed, and although the tumor was extremely hemorrhagic, it was mobilized easily off the compressed dura to achieve resection. RESULTS The postoperative course was uneventful. One month after her surgery, the patient's myelopathic symptoms had resolved, and the she was able to return to work. CONCLUSION Because the prognosis after surgical management of these lesions is favorable, the diagnosis of thrombosis involving a spinal angiolipoma should be considered in the differential diagnosis of subacute spinal cord compression.

Abstract
UNLABELLED Recent studies have shown different results concerning the effects of smoking on neuromuscular blocking agents. Some reports indicate that smokers need higher doses of vecuronium, but are more sensitive to atracurium. The aim of this study was to evaluate the effects of smoking on onset and recovery time after a single 0.6 mg/kg intubating dose of rocuronium an analog of vecuronium. METHODS Following institutional approval and informed consent, 20 smokers (> 10 cigarettes/day) and 20 nonsmokers were included in the study. Following oxazepam premedication and induction with fentanyl and thiopental, single-twitch stimulation of the ulnar nerve was performed every 10 s. Following stabilisation of control responses, patients received rocuronium 0.6 mg/kg for intubation. Anaesthesia was maintained with enflurane < or = 0.8 vol.% (end-tidal) and 65% nitrous oxide in oxygen. Onset time and recovery to 25% and 75% of the twitch control values were recorded. RESULTS Onset and recovery times were not different between smokers and nonsmokers. CONCLUSIONS The results of the present study suggest that chronic nicotine exposure does not change onset time or duration of rocuronium neuromuscular blockade. A previous study found a greater need for vecuronium in smokers and discussed stimulation of the neuromuscular junction and enhanced biotransformation due to the enzyme-inducing properties of nicotine. The differences in our results could be partly due to a longer period of refraining from smoking in our patients, leading to very low nicotine blood concentrations without the proposed receptor-stimulating effect. Another cause for different behaviour of the two analogs could be different elimination pathways. Recent investigations suggest that rocuronium may not be eliminated principally by the liver. Therefore, enhanced nicotine-induced biotransformation, as suggested for vecuronium, would not occur with rocuronium.

Abstract
OBJECTIVE Rocuronium is a new non-depolarising steroidal muscle relaxant with a short onset time. The present study was undertaken to compare intubating conditions as well as onset and clinical duration of a single dose of 0.6 mg/kg (2 x ED95) with a single dose of 1 mg/kg suxamethonium (3 x ED95). METHODS After obtaining informed consent and approval of the Ethics Committee, 40 adult patients (ASA I-III) participated in this study. After premedication with oxazepam, anaesthesia was induced with fentanyl and propofol and maintained with propofol, N2O and supplements of fentanyl as needed. Muscular relaxation was assessed by EMG recording of adductor pollicis muscle after supramaximal single twitch stimulation of the ulnar nerve every 10 s. Patients were allocated randomly to receive either rocuronium 0.6 mg/kg or suxamethonium 1 mg/kg. The following parameters were measured: intubating conditions 60 s after injection, onset time and clinical duration of neuromuscular block, % block at intubation, heart rate, blood pressure and arterial oxygen saturation. RESULTS (mean +/- SD). Intubating conditions after rocuronium and suxamethonium were found to be clinically acceptable (excellent or good) in 90% of patients, though there was only a partial blockade of the adductor pollicis muscle with rocuronium (71 +/- 23%) compared to suxamethonium (95 +/- 14%) (p < 0.05). The onset time and clinical duration of relaxation was shorter after suxamethonium (p < 0.05) and occurred at 0.8 +/- 0.2, 7 +/- 2.1 and 3.2 +/- 1.3, 29 +/- 11 min after suxamethonium and rocuronium respectively. CONCLUSION At a dosage of 0.6 mg/kg, rocuronium has an onset time of about 3 min and a clinical duration of relaxation of nearly half an hour. These data are supported by various studies, while others show shorter times, probably due to different monitoring techniques. In spite of the pharmacodynamic differences between suxamethonium and rocuronium, the intubating conditions after administration of both compounds are comparable and develop at the same rate.

Abstract
UNLABELLED Cimetidine is a commonly used H2-receptor antagonist that has been recommended for the prevention of acid aspiration syndrome and has been shown to potentiate vecuronium-induced neuromuscular block. The present study was designed to investigate the influence of a single IV dose of cimetidine on the neuromuscular effects of rocuronium, an analogue of vecuronium with a short onset time. METHODS Twenty adults aged 18-65 years were included in the study with their informed consent and approval of the Ethics Committee. Following oxazepam premedication, 10 patients were randomly allocated to receive cimetidine 400 mg IV 30 min before anaesthesia. After fentanyl and thiopentone induction, single-twitch stimulation of the ulnar nerve was performed every 10 s. Following stabilisation of control responses, patients received rocuronium 0.6 mg/kg for intubation. Anaesthesia was maintained with enflurane < or = 0.8 vol.% (end-tidal) and 65% nitrous oxide. Onset time and recovery times to 25% and 75% of the twitch control values were recorded. RESULTS Onset and recovery times did not differ between groups. CONCLUSIONS The results of the present study demonstrate that cimetidine does not increase the duration of rocuronium neuromuscular blockade. Inhibition of the cytochrome P450 system or a direct effect at the neuromuscular junction have been suggested as the mechanisms of drug interaction associated with cimetidine. Impairment of hepatic microsomal drug metabolism results in a prolonged duration of action of vecuronium, which appears to be eliminated primarily via the liver. Data on the elimination pathway of rocuronium in humans are not available. The fact that cimetidine does not alter the recovery from rocuronium-induced neuromuscular block confirms a previous suggestion that rocuronium may not be eliminated principally by the liver. A direct effect of cimetidine on the neuromuscular junction could not be confirmed by this study. Therefore, cimetidine can be given as premedication without a risk of prolonged rocuronium block.

Abstract
Acute pancreatitis was induced in 13 anesthetized dogs by retrograde injection of bile mixed with trypsin into the pancreatic duct. Six animals were treated with intravenous infusion of new synthetic antiprotease. Nafamostat Mesilate, at a dose of 1 mg/kg/h. Four out of seven untreated animals died during the experiment. All the treated dogs survived. Hemodynamic data were regularly monitored during a ten-hour observation period. Cardiac output, mean arterial pressure and left ventricular stroke volume decreased rapidly in the untreated animals. An increase in systemic vascular resistance and pulmonary vascular resistance was observed in dogs without treatment. Nafamostat Mesilate given as therapy significantly improved the hemodynamic parameters, and prevented the animals from developing shock. The study demonstrates an advantageous influence of synthetic antiprotease Nafamostat Mesilate on the course of acute experimental pancreatitis.

Abstract
In a group of 20 immunosuppressed women with lower genital neoplasia, evidence of associated human papillomaviral infection was found in all patients on the basis of the histologic identification of koilocytes in the upper strata of areas of mild or moderate dysplasia. Immunohistochemical study of similar areas disclosed human papilloma structural antigens in the lesions in 60%, while 50% had lesions in which human papilloma virions were detected by the electron microscope. An abnormal immunologic status, indicated by an altered T-helper/T-suppressor ratio, a deficient response to mitogenic stimulation, or both, was confirmed in 80% of the patients studied. Twelve of the 20 patients had unusually persistent and recurrent intraepithelial neoplasia, and in one the disorder progressed to invasive epidermoid carcinoma. The progressive behavior of human papillomavirus-associated neoplasia in these immunosuppressed patients might represent an accelerated version of the long-term course of such lesions in immunocompetent hosts.

Abstract
Human papillomavirus infections of the cervix were assessed in patients attending a colposcopy clinic. Of 348 patients with cervical biopsies, 134 (38.5%) had human papillomavirus infections, and of 251 patients with cervical intraepithelial neoplasia (CIN) 112 (44.6%) had human papillomavirus. The majority of patients with human papillomavirus had concurrent CIN (83.6%; 112/134). Patients with human papillomavirus were significantly younger than patients without human papillomavirus (24.4 versus 29.9 years mean age; P less than .001), had significantly milder degrees of CIN (84% versus 43% mild/moderate dysplasia; P less than .001), and had a significantly lower mean number of pregnancies (2.16 versus 3.05; P less than .001). A matched pairs analysis of 69 pairs showed the same distribution of CIN in both human papillomavirus and nonhuman papillomavirus patients. Electron microscopy of human papillomavirus--specific koilocytes confirmed the presence of human papillomavirus particles in the nuclei.

Abstract
Two patients are described with subcutaneous infections due to Phialophora richardsiae. Both were diabetics and originally came from subtropical areas. One of the patients had a cystic lesion which was well encapsulated while the other had a large ulcerating lesion with draining sinus tracts. The organisms were found to be susceptible to cycloheximide but resistant to 5-fluorocytosine, miconazole and amphotericin B. There was some variability in the degree of resistance depending upon whether the primary or secondary phialoconidia were tested. While simple excision appears curative for the solitary cystic type of lesion, therapy of the ulcerating form of the disease remains problematic.

Abstract
✓ Cerebral blood flow (CBF), intracranial pressure (ICP), brain metabolism (CMRO2), systemic arterial pressure (SAP), and arterial blood gases were measured in comatose patients, most of whom had suffered a head injury. The patients were divided into two groups according to whether a mass lesion was or was not demonstrated by bilateral carotid angiography. In the majority of patients a control run measuring regional cerebral blood flow (rCBF) was followed by a test of cerebral autoregulation; hypertonic mannitol was then administered. During the control period there was marked and unpredictable variability in all of the parameters recorded. There was no correlation between ICP or CBF and neurological status or CMRO2 except at very high levels of ICP. Autoregulation was intact in some patients and defective in others, and there was no correlation between the status of autoregulation on the one hand and CBF or survival on the other. Mannitol increased CBF in nearly all patients, to twice the control value in a few, and CMRO2 increased with CBF in several patients. The change in CBF was independent of the initial ICP or the response of ICP to mannitol. Thus, the relationship of these parameters was unpredictable in acutely brain-damaged patients; the status of autoregulation was also unpredictable.
