Complications of unintentional dural puncture during labour epidural analgesia: a 10-year retrospective observational study.

INTRODUCTION: Unintentional dural puncture (UDP) occurs in 0.5-1.5% of labour epidural analgesia cases. To date, little is known about evidence of UDP-related complications. This work aimed to assess the incidence of intrapartum and postpartum complications in parturients who experienced UDP. METHODS: This is a 10-year retrospective observational study on parturients admitted to our centre who presented UDP. Data collection gathered UDP-related complications during labour and postpartum. All women who displayed UDP received medical therapy and bed rest. An epidural blood patch (EBP) was not used in this population. Once asymptomatic, patients were discharged from the hospital. RESULTS: Out of 7718 neuraxial analgesia cases, 97 cases of UDP occurred (1.25%). During labour, complications appeared in a small percentage of analgesia procedures performed, including total spinal anaesthesia (1.0%), extended motor block (3%), hypotension (4.1%), abnormal foetal heart rate (2%), inadequate analgesia (14.4%), and general anaesthesia following neuraxial anaesthesia failure (33.3% of emergency caesarean sections). During the postpartum period, 53.6% of parturients exhibited a postdural puncture headache, 13.4% showed neurological symptoms, and 14.4% required neurological consultation and neuroimaging. No patient developed subdural hematoma or cerebral venous sinus thrombosis; one woman presented posterior reversible encephalopathy syndrome associated with eclampsia. Overall, 82.5% of women experienced an extension of hospital stay. CONCLUSION: Major complications occurred in a small percentage of patients during labour. However, since they represent high-risk maternal and neonatal health events, a dedicated anaesthesiologist and a trained obstetric team are essential. No major neurological complications were registered postpartum, and EBP was not performed. Nevertheless, all patients with UDP were carefully monitored and treated until complete recovery before discharge, leading to an extension of their hospitalization.

Prevalence and impact of symptoms suggestive of gastroesophageal reflux disease.

Few studies have focused on the impact of gastroesophageal reflux disease on general health and on work absenteeism. Our aim was to evaluate the prevalence and severity of symptoms suggestive of gastroesophageal reflux disease in two samples of Italian employees. We interviewed 424 subjects of S. Matteo Hospital staff and 344 subjects of the Military Factory of Pavia regarding the frequency and severity of heartburn and acid regurgitation during the last 12 months. Subjects were specifically asked whether symptoms interfered with the quality of work activities or determined work absenteeism. In all, 91% of eligible subjects responded. The prevalence rate per 100 of any heartburn or regurgitation experienced at least monthly was 21. This value increased to 45% taking into consideration symptoms experienced occasionally. Mild or moderate symptoms were more frequent than severe symptoms (P < 0.001). Only 2.6% of subjects answered that symptoms have a negative influence on the quality of their work. No work absenteeism was recorded. The study confirms that typical gastroesophageal reflux symptoms are common conditions, but mainly of mild or moderate degree.

Analysis of gastroduodenitis and oesophagitis in relation to dyspeptic/reflux symptoms.

BACKGROUND/AIMS: The pathogenesis of dyspeptic/reflux symptoms and the clinico-pathologic profile of affected patients are still poorly understood. To improve our knowledge in this field we carried out a systematic, comparative analysis of symptom profiles and histopathologic patterns of oesophagogastroduodenal mucosa in a series of 221 subjects, 140 with and 81 without endoscopic evidence of hiatal hernia. Of these, 190 showed reflux and/or dyspeptic symptoms. METHODS: Before endoscopy, all the subjects were questioned about the presence and severity of 12 individual symptoms. Biopsies were taken from the distal oesophagus, cardia, corpus, angulus, antrum and duodenal bulb, and were scored in accordance with the Sydney system. RESULTS: Patient groups with a distinct clinico-pathologic profile were better identified when symptoms of adequate severity were compared with histopathologic parameters. A correlation between gastroesophageal reflux disease (GORD) symptoms and histologic signs of oesophagitis was mostly restricted to patients endoscopically positive for oesophagitis. Retroxiphoid pyrosis correlated with cardial gastritis but not with oesophagitis, either endoscopic or histologic, while ulcer-like epigastric pain correlated with active duodenitis and distal gastritis. No definite histopathologic background was detected in patients with putative dysmotility-like symptoms, endoscopy-negative GORD and low score or mixed symptoms. CONCLUSION: A contribution of Helicobacter pylori gastroduodenitis to the pathogenesis of some dyspeptic symptoms seems likely. However, the identification of specific histologic changes causing individual symptoms remains rather elusive, with the exception of active antroduodenitis in patients with ulcer-like pain and of active proximal gastritis in patients with severe retroxiphoid pyrosis.

Distinct profiles of gastritis in dyspepsia subgroups. Their different clinical responses to gastritis healing after Helicobacter pylori eradication.

BACKGROUND: A contribution of Helicobacter pylori gastritis to the pathogenesis of non-ulcer dyspepsia (NUD) remains uncertain. METHODS: Administration of an appropriate clinical questionnaire followed by endoscopy allowed us to select, among 139 outpatients with dyspepsia, 87 non-ulcer dyspepsia patients with more severe and group-distinctive symptoms, 35 of whom were classified as having ulcer-like (ULD). 38 as dysmotility-like (DLD), and 14 as reflux-like dyspepsia (RLD). Biopsy specimens were evaluated for H. pylori gastritis in accordance with the Sydney system. The 70 H. pylori-positive cases were treated with omeprazole, 20 mg twice daily, and amoxycillin, 1 g three times daily for 2 weeks. RESULTS: Higher rates of H. pylori colonization were found histologically in the gastric mucosa of ULD (91%) and RLD (86%) than in that of DLD (68%) or asymptomatic (42%) patients. ULD differed from RLD patients in their higher score of antritis activity. Three and 6 months after H. pylori eradication ULD (but not DLD) showed significant regression of dypspetic symptoms scores. CONCLUSIONS: It seems likely that H. pylori gastritis, with special reference to active antritis, is among causative factors of ULD. Its role in the pathogenesis of RLD and DLD needs further investigation.
