Arthroscopy or arthrotomy for native knee septic arthritis: A systematic review.

Purpose: Septic arthritis of any joint is an orthopaedic emergency which requires prompt diagnosis and treatment. The knee is the commonest joint afflicted, and the primary objective of any treatment is complete source control. This commonly takes the form of antibiotic therapy and a washout of the infected joint by means of arthroscopy or arthrotomy. The primary aim of this review is to investigate if arthroscopic washout for native knee septic arthritis confers a lower risk of repeat procedure than arthrotomy. Methods: A systematic review and meta-analysis was conducted of the MEDLINE, SCOPUS and the Cochrane Library data bases. The primary outcome of interest was requirement for repeat washout with all-cause complications, length of inpatient stay and mortality secondary outcomes. Results: A total of 17,140 subjects were included for analysis of the primary outcome, and the overall rate of repeat procedure was 14.6%. No statistical difference was found between arthroscopy and arthrotomy for repeat washout (risk ratio 0.86 [95% confidence interval, CI: 0.72-1.02], I 2 = 36%). Eligible studies found in favour of arthroscopy for all-cause complication rate (risk ratio 0.75 [95% CI: 0.6-0.93], I 2 = 84%) and length of stay in hospital (mean difference -1.98 days [95% CI: -3.43 to -0.53], I 2 = 84%). No statistical difference was found for the mortality rate (risk ratio 1.17 [95% CI: 0.52-2.63], I 2 = 57%). Conclusion: Our analysis found arthroscopy and open arthrotomy to be equivocal for repeat surgical washout in native knee septic arthritis. All-cause complication rate and length of inpatient stay were favourable for arthroscopy with no difference noted between mortality rates. Level of Evidence: Level III.

Isolated Extensor Hallucis Longus Compartment Syndrome: A Case Report.

We present the case of an isolated extensor hallucis longus compartment syndrome following a diaphyseal fibular fracture. Our subject underwent syndesmotic fixation and experienced ongoing pain post-procedure. This was associated with an isolated loss of power in extension of the hallux. A diagnosis of an isolated extensor hallucis longus compartment syndrome followed. Our case highlights the vulnerability of this muscle belly to ischemia and reiterates the value of complete clinical examination in the postoperative patient.

Acetabular cup size trends in total hip arthroplasty.

BACKGROUND: Total hip arthroplasty (THA) is a common procedure for end stage osteoarthritis. The learning curve for THA is complex and challenging. One of the most difficult skills to master is acetabular reaming. We wish to identify if experience in arthroplasty leads to preservation of more bone stock. AIM: To investigate if increasing surgeon experience will predict an ever decreasing acetabular cup size. METHODS: A retrospective case series of four attending orthopaedic surgeons was completed. All uncemented elective total hip arthroplasties since appointment were selected for inclusion. The size of acetabular cup used was noted and logistic regression was used to identify if a trend to smaller cups existed. RESULTS: A total of 1614 subjects were included with a mean age of 64 years. Overall cups were on average 0.18mm smaller per year (95% confidence interval -0.25 to -0.11, P < 0.001). Individual surgeon trends showed cup sizes to decrease 0.27 mm/year for surgeon A, 0.02 mm/year for surgeon B, 0.15 mm/year for surgeon C and 0.29 mm/year for surgeon D. Three of the four surgeons had a more pronounced trend to smaller cups for male subjects than their female counterparts. CONCLUSION: We found increasing surgeon experience to be associated with an ever-decreasing acetabular cup size. Smaller acetabular cup size may act as a surrogate marker of surgical proficiency by virtue of decreased acetabular reaming.

Plain film of the abdomen remains a low sensitivity test in A&E.

BACKGROUND: Plain film abdomens (PFA) are frequently used in the emergency department to help guide the management of patients presenting with abdominal symptoms. A plain film abdomen contributes minimally to clinical scenarios due to low sensitivity and specificity. Is a PFA useful in the emergency setting or does it serve to further complicate decision making? AIM: We hypothesise that PFAs in the emergency department are over utilised to falsely reassure clinicians and patients alike. METHODS: A search of the National Integrated Medical Imaging System (NIMIS) database in an Irish tertiary referral hospital was conducted. All plain film abdominal radiographs requested by the emergency department between 01/01/2022 and 31/08/2022 were identified. Requests where there was suspicion of foreign body were excluded. A retrospective search of the NIMIS database identified subjects who underwent subsequent imaging. RESULTS: A total of 619 abdominal films were deemed suitable for inclusion. These comprised of 338 male and 282 female subjects. Subjects had an average age of 64 years. Fifty-seven per cent of PFAs detected no abnormality. Forty-two per cent of subjects had subsequent imaging. The plain film findings correlated with further imaging in only 15% of cases. One case of ruptured aortic aneurysm and 11 perforations were detected on computerised tomography, none of these cases were evident on abdominal X-ray. CONCLUSION: Plain film abdomen requests are over utilised in the emergency department. PFAs are not sensitive for detecting acute pathology and should not be used to decide if a patient requires further imaging or a full clinical assessment.

Does previous fragility fracture impact upon mortality in a hip fracture cohort? a retrospective study.

BACKGROUND: Fragility fractures are described as fractures resulting from low-energy trauma and are considered diagnostic of reduced bone mineral density or osteoporosis. They often present as hip fractures with hip fractures remaining a common but devastating injury among older patients. Many factors influence a patient's risk of hip fracture and their subsequent risk of death. AIM: In this study, we examined if previous fragility fracture impacts upon mortality after hip fracture. METHODS: This was a retrospective single-center cohort study of patients included in the Irish Hip Fracture registry over a 5-year time period. Epidemiological data including gender, age, type of fracture, type of surgery, bone protection medication, American Society of Anesthetics (ASA) grade, and post-fracture outcomes including death at 30 days and death at 1 year were recorded. The presence or absence of a previous fragility fracture was examined to explore if a previous fragility fracture was an independent predictor of mortality. RESULTS: There were 964 patients included, and 290 of whom had sustained a previous fragility fracture; 289 patients were males and 675 females, 33 patients had died in the 30 days following their surgery, and 180 patients had died within 1 year. We found statistically significant results for gender and age but not for previous fragility fracture influencing mortality (p value 0.230). CONCLUSION: We found that previous fragility fracture does not impact upon mortality in a hip fracture cohort. However, gender and age did impact upon mortality in this study.

Laparoscopic sleeve gastrectomy is safe and effective in elderly patients: a comparative analysis.

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) is gaining widespread popularity as a definitive bariatric operation that provides satisfactory and durable weight loss as well as comorbidity resolution. Although SG is being increasingly offered to patients of all ages, there is a paucity of reported outcomes in patients ≥62 years of age. The purpose of this study was to perform a comparative analysis of the outcomes of SG in patients >62 years versus a younger age group, with an emphasis on safety and efficacy. METHODS: A retrospective analysis was performed from a prospectively collected database on patients who underwent SG from 2007 to 2012. All patients who were ≥62 years old were compared to those <62 years. RESULTS: There were 182 patients who underwent SG, 17 of whom were ≥62 years old. There were no significant differences in demographics or comorbidity characteristics between the groups. The mean follow-up was 1 year. There was no 30-day mortality in either group. The percent excess weight loss for the younger age group was 44 ± 21 % and the older group was 44 ± 25 %. The percent total body weight loss was 22 ± 10 and 21 ± 10 %, respectively. Weight loss outcomes were maintained for up to 3 years. Comorbidity resolution and improvement rates were equivalent in both groups. CONCLUSIONS: SG is safe and effective in patients ≥62 years. Weight loss and the beneficial effects on comorbidities are equivalent among elderly and younger patients. SG should be offered to elderly patients who are deemed to be appropriate candidates.

What is wrong with the training of general surgery?

The practice of surgery has undergone tumultuous changes over the last 30 years. Disease management, trauma volume, operative techniques, supervision requirements, and allocation of work hours have all changed, resulting in a substantial impact on general surgical training. Changes need to occur in the structure, assessment, and mentorship of future residents to prepare them to enter the marketplace and practice safe medicine with confidence and authority.

Laparoscopic transgastric gastroplasty: a novel technique for a large esophagogastric fistula.

Esophagogastric fistula is a rare complication related to severe inflammation at the gastroesophageal junction. Most causes are related to severe gastroesophageal reflux disease, previous surgery, or malignancy. This is the case of a 72-year-old man who had a laparoscopic Nissen fundoplication. He developed an esophageal obstruction from an intraesophageal pledget. It was removed laparoscopically, and the esophagotomy was buttressed with a Nissen fundoplication. Two months later he developed severe dysphagia, and an esophagogastric fistula was diagnosed. This was a large fistula measuring 20 mm in diameter. A novel hybrid technique was used to divide the fundoplication. Under endoscopic guidance, a 12-mm balloon-tipped trocar was inserted transgastrically. A linear-cutting surgical stapler was used to divide the fundoplication and reopen the gastroesophageal junction. The patient had no further dysphagia or gastroesophageal reflux.

Revisional bariatric surgery is more effective for improving obesity-related co-morbidities than it is for reinducing major weight loss.

BACKGROUND: Patients having previous bariatric surgery are at risk for weight regain and return of co-morbidities. If an anatomic basis for the failure is identified, many surgeons advocate revision or conversion to a Roux-en-Y gastric bypass. The aim of this study was to determine whether revisional bariatric surgery leads to sufficient weight loss and co-morbidity remission. PATIENTS AND METHODS: From 2005-2012, patients undergoing revision were entered into a prospectively maintained database. Perioperative outcomes, including complications, weight loss, and co-morbidity remission, were examined for all patients with a history of a previous vertical banded gastroplasty (VBG) or Roux-en-Y gastric bypass (RYGB). RESULTS: Twenty-two patients with a history of RYGB and 56 with a history of VBG were identified. Following the revisional procedure, the RYGB group experienced 35.8% excess weight loss (%EWL) and a 31.8% morbidity rate. For the VBG group, patients experienced a 46.2% %EWL from their weight before the revisional operation with a 51.8% morbidity rate. Co-morbidity remission rate was excellent. Diabetes (VBG:100%, RYGB: 85.7%), gastroesophageal reflux disease (VBG: 94.4%, RYGB: 80%), and hypertension (VBG: 74.2%, RYGB:60%) demonstrated significant improvement. CONCLUSION: Revision of a failed RYGB or conversion of a VBG to a RYGB provides less weight loss and a higher complication rate than primary RYGB but provides an excellent opportunity for co-morbidity remission.

Incidence of gastrojejunostomy stricture in laparoscopic Roux-en-Y gastric bypass using an autologous fibrin sealant.

BACKGROUND: Anastomotic leak at the gastrojejunostomy is a life-threatening complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Fibrin sealants have been used as topical adjuncts to reduce leaks at the gastrojejunostomy. Our clinical observations suggest that an unintended consequence may be the promotion of anastomotic stricture. We hypothesized that the use of fibrin sealant at the gastrojejunostomy in patients undergoing LRYGB decreases the incidence of anastomotic leak but increases the incidence of clinically significant stricture. METHODS: Following institutional review board approval, medical records of patients undergoing LRYGB by two surgeons at a single institution over a 5-year period were retrospectively reviewed. Preoperative demographics and postoperative complication rates including incidence of gastrojejunostomy leak and endoscopically diagnosed stricture requiring dilation within 1 year of surgery were recorded. RESULTS: Four hundred twenty-five patients had fibrin sealant routinely applied to their gastrojejunostomy site and 104 did not. Four leaks occurred in the sealant group and two leaks occurred in the control group (p = 0.2). Of patients who received sealant, 1.6 % needed postoperative blood transfusion compared to 4.8%of those who did not receive sealant (p=0.05) [corrected]. There was a significantly increased rate of strictures requiring dilation in the sealant group (11.3% compared to 4.8% stricture rate in patients who did not receive sealant, p = 0.04). CONCLUSIONS: In our experience, the use of fibrin sealant at linear stapled gastrojejunostomy site during LRYGB increases the incidence of clinically significant postoperative stricture and does not reduce the incidence of anastomotic leak.

The effect of subgingival ozone and/or hydrogen peroxide on the development of peri-implant mucositis: a double-blind randomized controlled trial.

PURPOSE: This double-blind randomized controlled trial assessed the effect of subgingival ozone (O3, gaseous ozone, HealOzone MK II, KaVo) and/or hydrogen peroxide (H2O2) on the development of peri-implant mucositis. MATERIALS AND METHODS: Twenty subjects (mean age, 60 ± 7.7 years) with 80 implants (4 implants each) were recruited. First, a 2-week pretrial phase took place to achieve healthy gingiva. Subsequently, partial gum shields were constructed for the experimental area (around the 4 implants); subjects were asked to refrain from brushing in that area by wearing the gum shield. The following treatments were randomly applied (for 60 seconds) to implant sites on days 0, 7, and 14: (1) air (O2) and saline (0.9% NaCl) (control group), (2) O2 and H2O2 (3%), (3) O3 and saline, and (4) O3 and H2O2. Plaque, gingival, and bleeding indices were recorded on days 0, 7, 14, and 21. RESULTS: Significant differences were seen among the treatments (P < .01) in plaque (F = 16.68), modified gingival (F = 7.86), and bleeding (F = 18.42) indices. O3 + saline and O3 + H2O2 produced optimum gingival health scores and were equally effective and the most effective in controlling bleeding (mean score = 0.05), while O2 + saline was the least effective (mean score = 0.56). CONCLUSION: Ozone showed great potential for management of peri-implant mucositis.

Iatrogenic intestinal and mesenteric injuries with small bowel volvulus following use of barbed suture during laparoscopic myomectomy.

This is a case report of a patient who developed major intestinal complications after the utilization of barbed sutures for an off-label indication. The report serves as a warning for patients and surgeons of the potential injuries that may be caused by the use of new products in unapproved indications.

Deep sedation in natural orifice transluminal endoscopic surgery (NOTES): a comparative study with dogs.

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) has been mostly performed with the animal under general and inhalational anesthesia (IA-NOTES). To date, NOTES using propofol sedation (PS-NOTES) has not been investigated. This study aimed to assess the feasibility and safety of PS-NOTES for transgastric oophorectomy with carbon dioxide insufflation and to compare its success rates with those of conventional IA-NOTES. METHODS: In this prospective randomized study, NOTES oophorectomy was performed for 19 female dogs randomized to two conditions: PS (study group) and IA (control group). Sedation success rates (ability to visualize and resect ovaries without converting to IA), operative success rates (ability to resect and retrieve both ovaries in full using only NOTES), and vital parameters including hemodynamic and respiratory changes were documented. RESULTS: In the PS-NOTES group (n = 9), the sedation success rate was 100 %. The operative success rate was 67 % (6 of 9 animals) compared with 80 % (8 of 10 animals) in the IA-NOTES group. No purposeful movement occurred during surgical manipulation and no respiratory or cardiovascular complications in occurred the PS group. Heart rate (HR) and end-tidal carbon dioxide (ETCO(2)) were significantly higher in the PS group than in the IA group. Blood pressure (BP) was significantly higher in the PS group only during the middle part of the procedure. Only mild respiratory depression was noted in the PS group, as indicated by elevated but acceptable ETCO(2). Elevations in BP and HR are thought to be related to elevated CO(2) but did not appear to have an adverse impact on the course of the procedure. Recovery was uneventful for all the animals. CONCLUSION: The use of PS-NOTES appears to be feasible, resulting in outcomes comparable with those for IA in dogs. Further studies are needed to determine the applicability of this concept in human NOTES.

Management of children undergoing cardiac transplantation with high Panel Reactive Antibodies.

Highly sensitised children in need of cardiac transplantation have overall poor outcomes because of increased risk for dysfunction of the cardiac allograft, acute cellular and antibody-mediated rejection, and vasculopathy of the cardiac allograft. Cardiopulmonary bypass and the frequent use of blood products in the operating room and cardiac intensive care unit, as well as the frequent use of homografts, have predisposed potential recipients of transplants to allosensitisation. The expansion in the use of ventricular assist devices and extracorporeal membrane oxygenation has also contributed to increasing rates of allosensitisation in candidates for cardiac transplantation. Antibodies to Human Leukocyte Antigen can be detected before transplantation using several different techniques, the most common being the "complement-dependent lymphocytotoxicity assays". "Solid-phase assays", particularly the "Luminex® single antigen bead method", offer improved specificity and more detailed information regarding specificities of antibodies, leading to improved matching of donors with recipients. Allosensitisation prolongs the time on the waiting list for potential recipients of transplantation and increases the risk of complications and death after transplantation. Aggressive reduction of antibodies to Human Leukocyte Antigen in these high-risk patients is therefore of vital importance for long-term survival of the patient and cardiac allograft. Strategies to decrease Panel Reactive Antibody or percent reactive antibody before transplantation include plasmapheresis, intravenous administration of immunoglobulin, and specific treatment to reduce B-cells, particularly Rituximab. These strategies have resulted in varying degrees of success. Antibody-mediated rejection and cardiac allograft vasculopathy are two of the most important complications of transplantation in patients with high Panel Reactive Antibody. The treatment of antibody-mediated rejection in recipients of cardiac transplants is largely empirical and includes the use of high-dose corticosteroids, plasmapheresis, intravenous administration of immunoglobulins, anti-thymocyte globulin, and Rituximab. Cardiac allograft vasculopathy is believed to be secondary to chronic complement-mediated endothelial injury and chronic vascular rejection. The use of proliferation signal inhibitors, such as sirolimus and everolimus, has been shown to delay the progression of cardiac allograft vasculopathy. In some non-sensitised recipients of cardiac transplants, the de novo formation of antibodies to Human Leukocyte Antigen after transplantation may increase the likelihood of adverse clinical outcomes. The use of serial testing for donor-specific antibodies after cardiac transplantation may be advisable in patients with frequent episodes of rejection and patients with history of sensitisation. Allosensitisation before transplantation can negatively influence outcomes after transplantation. A high incidence of antibody-mediated rejection and graft vasculopathy can result in graft failure and decreased survival. Current strategies to decrease allosensitisation have helped to expand the pool of donors, improve times on the waiting list, and decrease mortality. Centres of transplantation offering desensitisation are currently using plasmapheresis to remove circulating antibodies; intravenous immunoglobulin to inactivate antibodies; cyclophosphamide to suppress B-cell proliferation; and Rituximab to deplete B-lymphocytes. Similar approaches are also used to treat antibody-mediated rejection after transplantation with promising results.

Lessons learned from 119 consecutive cardiac transplants for pediatric and congenital heart disease.

BACKGROUND: This manuscript reviews all patients who underwent orthotopic heart transplantations (OHT) at our program (116 patients underwent 119 OHT) to describe their diagnostic characteristics and to assess risk factors for mortality. METHODS: Median age at OHT was 179 days (mean, 1,446.6 ± 188.9 days [4.0 ± 0.5 years]; range, 5 days to 7,125 days [19.5 years]; 15 neonates, 68 infants). Median weight at OHT was 5.5 kg (mean, 17.2 ± 2.1 kg; range, 2.2 to 113 kg). Diagnoses were cardiomyopathy (n = 37), primary transplantation for hypoplastic left heart syndrome (HLHS) or HLHS-related malformation (n = 29), transplantation after prior cardiac surgery for HLHS or HLHS-related malformation (n = 9), non-HLHS congenital heart disease (n = 39), and retransplant (n = 5). RESULTS: Overall Kaplan-Meier 5-year survival was 72.7%. Operative mortality was 12.6% (15 patients). Late mortality was 13.4% (16 patients). Eighty-five patients survived, with a mean follow-up of 5.76 ± 0.48 years (median, 5.1 years; range, 0.12 to 14.0 years). Total follow-up was 507.0 years. No survival difference was seen among the five diagnostic subgroups (p = 0.20). Univariate association between risk factors and survival was assessed for the following variables: age (p = 0.91), weight (p = 0.86), sex (p = 0.47), race (p = 0.40), insurance classification (p = 0.42), high PRA (p = 0.20), pretransplant mechanical circulatory support (p < 0.001), posttransplant mechanical circulatory support (p < 0.001), redo sternotomy (p = 0.07), heterotaxy (p = 0.02), cardiopulmonary bypass time (p = 0.01), and donor heart cross-clamp time (p = 0.02). CONCLUSIONS: Excellent results are expected for children undergoing OHT regardless of diagnostic classification. Pretransplant mechanical circulatory support, posttransplant mechanical circulatory support, cardiopulmonary bypass time, donor heart cross-clamp time, and heterotaxy are risk factors for decreased survival.

Gastrointestinal symptoms and patient satisfaction more than 1 year after laparoscopic Nissen fundoplication.

BACKGROUND: Symptoms from poorly controlled gastroesophageal reflux disease (GERD) such as heartburn and regurgitation often resolve after laparoscopic Nissen fundoplication. Unfortunately, new gastrointestinal symptoms such as bloating may occur for some patients. Accurate data regarding the gastrointestinal symptoms experienced by patients who have had a laparoscopic fundoplication may help patients to make more informed decisions about pursuing surgery for their reflux disease. METHODS: Patients more than 12 months after a laparoscopic Nissen fundoplication were mailed symptom surveys. Before surgery, all the patients had medically refractory esophageal symptoms (heartburn, regurgitation, or both). Surveys included the Gastrointestinal Quality of Life Index (GIQLI) and questions regarding satisfaction, reintervention, and medication use. Responses for individual GIQLI items were evaluated to determine the gastrointestinal symptoms experienced by fundoplication patients and the relationship of these symptoms to patient satisfaction. RESULTS: Of the 76 patients eligible for inclusion in the survey, 48 returned complete surveys (63%). The mean time since surgery was 28±9 months. No patient experienced frequent regurgitation, and few (10%) reported frequent heartburn at follow-up assessment. No patient required redo fundoplication during the follow-up period. Acid reduction medications were resumed by 25% of the patients, but not all of these patients resumed medications for recurrent GERD symptoms (15% total). After surgery, frequent bloating (21%) and excessive flatus (46%) were often noted. Satisfaction with the results of surgery was high, including 83% of the patients. CONCLUSIONS: Few patients report frequent regurgitation or heartburn after laparoscopic Nissen fundoplication. Although some patients resume acid reduction medications, many do so for reasons other than recurrent GERD symptoms. Most fundoplication patients are quite satisfied with the symptomatic results of surgery, although frequent functional gastrointestinal symptoms are common.

Gastric electrical stimulation is an effective and safe treatment for medically refractory gastroparesis.

BACKGROUND: Gastroparesis is characterized by delayed gastric emptying in the absence of obstruction. Common symptoms include nausea, vomiting, and abdominal pain. Severe gastroparesis can result in recurrent hospitalizations, malnutrition, and even death. Gastric electrical stimulation (GES) is a low morbidity treatment that may be effective in patients who are refractory to medical therapy. METHODS: For a period of more than 35 months, 19 GES systems were implanted laparoscopically for refractory gastroparesis of diabetic (DG, n = 10), idiopathic (IG, n = 6), or postsurgical (PSG, n = 3) etiology. Total gastroparesis symptom scores (TSS) and weekly vomiting frequency were assessed. Gastric emptying studies were attained preoperatively and after 6 months. RESULTS: Mean follow-up was 38 weeks. There were no major complications. Within 6 weeks, frequency of vomiting decreased in 75% of DG (6/8) and 100% of IG (4/4) patients. No PSG patient complained of vomiting preoperatively. Mean TSS scores improved significantly at all intervals out to 1 year. Gastric emptying studies normalized in 80% of DG patients but in only 1 of the 6 patients with gastroparesis due to other causes. CONCLUSION: GES therapy can lead to improvement in symptoms of gastroparesis and frequency of vomiting within 6 weeks. This therapy is a low morbidity treatment option that may help patients whose symptoms fail to improve with medical therapy.

Ultrasonic evidence of placental calcification at 36 weeks' gestation: maternal and fetal outcomes.

BACKGROUND: To determine the significance of an inappropriately mature placenta on ultrasound examination (Grannum classification), in a low-risk obstetric population. Scans were performed at 36 weeks' gestation. The study group comprised patients demonstrating a grade III placenta, and the control group comprised patients not demonstrating a grade III placenta. METHODS: A total of 1802 low-risk patients were scanned using serial directed real-time ultrasound at 36 weeks' gestation to determine placental maturity. RESULTS: The incidence of a grade III placenta at 36 weeks' gestation was 3.8% (68/1802). A grade III placenta was associated with young maternal age and cigarette smoking, p < 0.01. The incidence of proteinuric pregnancy-induced hypertension in the study and control groups was 7.4% (5/68) and 1.56% (27/1734), respectively, p < 0.01. The proportion of infants with a weight less than the 10th centile at birth in the study and control groups was 17.6% (12/68) and 5.6% (97/1734), respectively, p < 0.01. CONCLUSIONS: Ultrasound detection of a grade III placenta at 36 weeks' gestation in a low-risk population helps to identify the "at-risk" pregnancy. It helps to predict subsequent development of proteinuric pregnancy-induced hypertension and may help in identifying the growth-restricted baby.

Helicobacter pylori infection and dyspepsia in pregnancy.

OBJECTIVE: To investigate the relationship of Helicobacter pylori infection with dyspeptic symptoms in early and late pregnancy. Infection with H pylori and pregnancy outcome were also assessed. METHODS: H pylori seropositivity was determined in 416 antenatal patients at 10 to 14 weeks' gestation. Dyspeptic symptoms were recorded at 10 to 14 weeks' gestation and at 30 to 32 weeks' gestation by means of a well-validated questionnaire. Details of pregnancy outcome were recorded from patients' case notes. RESULTS: The incidence of H pylori infection in our population was 41.8% (164 of 404). Patients infected with H pylori were no more likely than controls to experience dyspepsia at 10 to 14 weeks' or at 30 to 32 weeks' gestation (P =.75 and.43, respectively). CONCLUSION: H pylori infection was not associated with preterm delivery, non reassuring fetal status in labor, or birth weight less than the 10th centile (P =.17,.57, and.19, respectively).H pylori infection is not associated with an increase in dyspepsia or with maternal or neonatal morbidity.
