Clinical characteristics and outcome of patients with autoimmune encephalitis: clues for paraneoplastic aetiology.

BACKGROUND AND PURPOSE: Autoimmune encephalitis (AE) represents a complex syndrome with diverse clinical manifestations and therapeutic outcomes. The aim of this study was to report the clinical characteristics and the long-term outcome of patients with paraneoplastic and idiopathic AE. METHODS: All patients with subacute encephalopathy admitted to the Neurology Department of our Institution from January 2012 to May 2019 were consecutively enrolled. Patients' serum and cerebrospinal fluid were tested for neural-specific autoantibodies by indirect immunofluorescence assays on mouse brain, rat neurons, cell-based assays and immunoblots. Outcome was assessed by the modified Rankin Scale score. RESULTS: From 107 adult patients with subacute encephalopathy, 50 patients were finally diagnosed with AE. Neural antibodies (Abs) were detected in 45/50 patients (90%). Leucine-rich glioma-inactivated protein 1 immunoglobulin G was the most frequent (6/50, 12%) Ab specific to neural surface antigens detected in adults with AE. Paraneoplastic encephalitis was diagnosed in 16/50 patients (32%). The presence of bilateral temporal lobe lesions on magnetic resonance imaging and cerebrospinal fluid restricted oligoclonal bands was associated with a higher probability to detect cancer at the time of AE diagnosis. All patients with Abs to neural surface antigens had a good outcome at last follow-up. Severe disability at AE onset and the lack of long-term immunosuppression predicted a poor outcome. CONCLUSIONS: Leucine-rich glioma-inactivated protein 1 immunoglobulin G was the most frequent Ab detected. Patients with bilateral temporal lobe lesions and oligoclonal bands have a higher probability to harbour an occult tumour. In these patients, a strict surveillance and monitoring for cancer detection is recommended.

Assessment of neurological manifestations in hospitalized patients with COVID-19.

BACKGROUND AND PURPOSE: The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2. METHODS: Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group. RESULTS: In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection. CONCLUSIONS: Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

Subgroup comparison according to clinical phenotype and serostatus in autoimmune encephalitis: a multicenter retrospective study.

BACKGROUND AND PURPOSE: Autoimmune encephalitides (AE) include a spectrum of neurological disorders whose diagnosis revolves around the detection of neuronal antibodies (Abs). Consensus-based diagnostic criteria (AE-DC) allow clinic-serological subgrouping of AE, with unclear prognostic implications. The impact of AE-DC on patients' management was studied, focusing on the subgroup of Ab-negative-AE. METHODS: This was a retrospective multicenter study on patients fulfilling AE-DC. All patients underwent Ab testing with commercial cell-based assays (CBAs) and, when available, in-house assays (immunohistochemistry, live/fixed CBAs, neuronal cultures) that contributed to defining final categories. Patients were classified as Ab-positive-AE [N-methyl-d-aspartate-receptor encephalitis (NMDAR-E), Ab-positive limbic encephalitis (LE), definite-AE] or Ab-negative-AE (Ab-negative-LE, probable-AE, possible-AE). RESULTS: Commercial CBAs detected neuronal Abs in 70/118 (59.3%) patients. Testing 37/48 Ab-negative cases, in-house assays identified Abs in 11 patients (29.7%). A hundred and eighteen patients fulfilled the AE-DC, 81 (68.6%) with Ab-positive-AE (Ab-positive-LE, 40; NMDAR-E, 32; definite-AE, nine) and 37 (31.4%) with Ab-negative-AE (Ab-negative-LE, 17; probable/possible-AE, 20). Clinical phenotypes were similar in Ab-positive-LE versus Ab-negative-LE. Twenty-four/118 (20.3%) patients had tumors, and 19/118 (16.1%) relapsed, regardless of being Ab-positive or Ab-negative. Ab-positive-AE patients were treated earlier than Ab-negative-AE patients (P = 0.045), responded more frequently to treatments (92.3% vs. 65.6%, P < 0.001) and received second-line therapies more often (33.3% vs. 10.8%, P = 0.01). Delays in first-line therapy initiation were associated with poor response (P = 0.022; odds ratio 1.02; confidence interval 1.00-1.04). CONCLUSIONS: In-house diagnostics improved Ab detection allowing better patient management but was available in a patient subgroup only, implying possible Ab-positive-AE underestimation. Notwithstanding this limitation, our findings suggest that Ab-negative-AE and Ab-positive-AE patients share similar oncological profiles, warranting appropriate tumor screening. Ab-negative-AE patients risk worse responses due to delayed and less aggressive treatments.

Lateral meniscal cysts: long-term clinical and radiological results of a partial meniscectomy and percutaneous decompressive needling.

INTRODUCTION: The aim of this study was to describe clinical and radiological long-term results of an arthroscopic partial meniscectomy associated with an outside-in decompressive needling of the cyst for lateral parameniscal cyst. METHODS: Eighteen patients with symptomatic parameniscal cysts treated between April 2002 and September 2009 were retrospectively included in the study. All patients underwent arthroscopic partial meniscectomy (preserving peripheral rim) and needling of the cyst using a 20-gauge needle. Pre- and post-operative IKDC, Tegner, and Lysholm scores were used to evaluate clinical results. Radiological results were obtained from pre- and post-operative radiographies and post-operative MRI scans. Both supine and weight bearing MRI examinations were performed. Kellgren-Lawrence and WORMS scales were used to evaluate osteoarthritis development of the knee. RESULTS: The mean follow-up period was 11.6 ± 2.6 years (range 7-15). Horizontal lesions were found in 56% of patients. All patients fully recovered. Mean Lysholm scores passed from mean pre-operative value 52 ± 16.9 to post-operative 85 ± 11.9 (P < 0.01) and mean IKDC scale score changed from 49.5 ± 14.7 to 67 ± 23.5 (P < 0.01). Mean Tegner scores did not change significantly. Post-operative radiographies showed a Kellgren-Lawrence scale grade 0 in six patients (33%), a grade I in eight (44%), a grade II in three (17%), and a grade III in one patient (6%). No patients were found with a Kellgren-Lawrence scale grade IV. No significant differences with pre-operative radiographies were found (chi-square = 1.867; df = 3; P = 0.60) in osteoarthritis development of the knee. Reported WORMS scores had an average of 12.4 ± 5.1. No recurrence of any cysts was observed. DISCUSSION: Different treatments for lateral meniscal cysts have been proposed, but proper management of the cyst is still controversial. The results of this study suggest that the outside-in needling of the cyst associated with partial meniscectomy is a highly effective, simple, and repeatable technique. Excellent clinical outcomes were reported at a mean follow-up of 11.6 ± 2.6 years (range 7-15). Imaging evaluation showed no significant evolution to osteoarthritis of the knee. CONCLUSIONS: Partial arthroscopic meniscectomy associated with percutaneous decompressive needling of the cyst wall under arthroscopic visualization showed positive clinical and radiological long-term results. Neither traditional radiographies nor innovative standing MRIs showed findings of osteoarthritis.

The association of pre-operative body pain diagram scores with pain outcomes following total knee arthroplasty.

OBJECTIVE: Approximately 20% of total knee arthroplasty (TKA) recipients have suboptimal pain relief. We evaluated the association between pre-surgical widespread body pain and incomplete pain relief following TKA. METHOD: This prospective analysis included 241 patients with knee osteoarthritis (OA) undergoing unilateral TKA who completed questionnaires preoperatively and up to 12 months post-operatively. Questionnaires included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scale and a body pain diagram. We derived the number of non-index painful body regions from the diagram. We used Poisson regression to determine the association between painful body regions identified preoperatively and both WOMAC pain at follow-up and improvement in pain as defined by the minimal clinically important difference (MCID). RESULTS: Mean subject age was 66 years (SD 9), and 61% were females. Adjusting for age, sex, co-morbid conditions, baseline pain, pain catastrophizing, and mental health, we found that more widespread body pain was associated with a higher likelihood of reporting 12-month WOMAC pain score >15 (relative risk [RR] per painful body region 1.39, 95% CI 1.18-1.63) and a greater likelihood of failing to achieve the MCID (RR 1.47, 95% CI 1.16-1.86).). Pain catastrophizing was an independent predictor of persistent pain and failure to improve by the MCID (RR 3.57, 95% CI 1.73-7.31). CONCLUSIONS: Pre-operative widespread pain was associated with greater pain at 12-months and failure to reach the MCID. Widespread pain as captured by the pain diagram, along with the pain catastrophizing score, may help identify persons with suboptimal TKA outcome.

Dark-induced senescence of barley leaves involves activation of plastid transglutaminases.

Transglutaminases (E.C. 2.3.2.13) catalyze the post-translational modification of proteins by establishing ε-(γ-glutamyl) lysine isopeptide bonds and by the covalent conjugation of polyamines to endo-glutamyl residues of proteins. In light of the confirmed role of transglutaminases in animal cell apoptosis and only limited information on the role of these enzymes in plant senescence, we decided to investigate the activity of chloroplast transglutaminases (ChlTGases) and the fate of chloroplast-associated polyamines in Hordeum vulgare L. 'Nagrad' leaves, where the senescence process was induced by darkness (day 0) and continued until chloroplast degradation (day 12). Using an anti-TGase antibody, we detected on a subcellular level, the ChlTGases that were associated with destacked/degraded thylakoid membranes, and beginning on day 5, were also found in the stroma. Colorimetric and radiometric assays revealed during senescence an increase in ChlTGases enzymatic activity. The MS/MS identification of plastid proteins conjugated with exogenous polyamines had shown that the ChlTGases are engaged in the post-translational modification of proteins involved in photosystem organization, stress response, and oxidation processes. We also computationally identified the cDNA of Hv-Png1-like, a barley homologue of the Arabidopsis AtPng1 gene. Its mRNA level was raised from days 3 to 10, indicating that transcriptional regulation controls the activity of barley ChlTGases. Together, the presented results deepen our knowledge of the mechanisms of the events happened in dark-induced senescence of barley leaves that might be activation of plastid transglutaminases.

The detection of neural autoantibodies in patients with antiepileptic-drug-resistant epilepsy predicts response to immunotherapy.

BACKGROUND AND PURPOSE: The detection of antibodies binding neural antigens in patients with epilepsy has led to the definition of 'autoimmune epilepsy'. Patients with neural antibodies not responding to antiepileptic drugs (AEDs) may benefit from immunotherapy. Aim of this study was to evaluate the frequency of autoantibodies specific to neural antigens in patients with epilepsy and their response to immunotherapy. METHODS: Eighty-one patients and 75 age- and sex-matched healthy subjects (HS) were enrolled in the study. Two groups of patients were included: 39 patients with epilepsy and other neurological symptoms and/or autoimmune diseases responsive to AEDs (group 1) and 42 patients with AED-resistant epilepsy (group 2). Patients' serum and cerebrospinal fluid were evaluated for the presence of autoantibodies directed to neural antigens by indirect immunofluorescence on frozen sections of mouse brain, cell-based assays and a radioimmunoassay. Patients with AED-resistant epilepsy and neural autoantibodies were treated with immunotherapy and the main outcome measure was the reduction in seizure frequency. RESULTS: Neural autoantibodies were detected in 22% of patients (18/81), mostly from the AED-resistant epilepsy group (P = 0.003), but not in HS. Indirect immunofluorescence on mouse brain revealed antibodies binding to unclassified antigens in 10 patients. Twelve patients received immunotherapy and nine (75%) achieved >50% reduction in seizure frequency. CONCLUSIONS: A significant proportion of patients with AED-resistant epilepsy harbor neural-specific autoantibodies. The detection of these antibodies, especially of those binding to synaptic antigens, may predict a favorable response to immunotherapy, thus overcoming AED resistance.

Neurotrophic keratitis.

Neurotrophic keratitis (NK) is a rare degenerative corneal disease that occurs as a result of partial or total impairment of trigeminal innervations, leading to a reduction (hypoesthesia) in or loss (anaesthesia) of corneal sensitivity. The impairment of sensory innervation causes a reduction in the lacrimation reflex and the vitality, metabolism and mitosis of epithelial cells, with subsequent deficiency in epithelial repair, stromal and intracellular oedema, loss of microvilli, and abnormal development of the basal lamina. Several recent studies have proposed different therapies based on different aetiopathogenetic theories. The aim of the therapy is to treat aetiopathogenesis and, at the same time, promote corneal healing. In this paper, we report the aetiology, diagnosis, management, and medical and surgical treatment of NK, also indicating future treatments based on the most recent studies.

Efficacy of combined antiviral therapy with lamivudine and tenofovir in a liver transplanted girl with de novo hepatitis B virus infection.

The management of de novo hepatitis B (HBV) infection in children after liver transplantation is not well defined. Because this infection may induce severe liver disease in the graft liver, an efficient antiviral therapy is desirable. Here, we describe the favorable viral outcome observed in a liver transplanted girl with de novo HBV infection following combination therapy with lamivudine and tenofovir.

ACL reconstruction with hamstrings: how different technique and fixation devices influence bone tunnel enlargement.

BACKGROUND: Bone tunnel enlargement after anterior cruciate ligament (ACL) reconstruction is well documented in the literature. The cause of this tunnel enlargement is unclear, but is thought to be multifactorial, with mechanical and biological factors playing a role. AIM: The aim of this prospective study was to evaluate how the different techniques may affect the bone tunnel enlargement and clinical outcome. PATIENTS AND METHODS: Forty-five consecutive patients undergoing ACL reconstruction with autologous doubled semitendinosus and gracilis tendons entered this study. They were randomly assigned to enter group A (In-Out technique, with cortical fixation and Interference screw) and group B (Out-In technique, metal cortical fixation on the femour and tibia). At a mean follow-up of 10 months, all the patients underwent CT scan exam to evaluate the post-operative diameters of both femoral and they underwent tibial tunnels clinical examination after 24 months. RESULTS: The mean femoral tunnel diameter increased significantly from 9.05±0.3 mm to 10.01±2.3 mm in group A and from 9.04±0.8 mm to 9.3±1.12 mm in group B. The mean increase in femoral tunnel diameters observed in group A was significantly higher than that observed in group B (p < 0.05) The mean tibial tunnel diameter increased significantly from 9.03±0.04 mm to 10.68±2.5 mm in group A and from 9.04±0.03 mm to 10.±0.78 mm in group B. The mean increase in tibial tunnel diameters observed in group A was significantly higher than that observed in group B (p < 0.05). No clinical differences were found between two groups and no correlations between clinical and radiological results were found in any patients of both groups. CONCLUSIONS: Results of the study suggest that different mechanical fixation devices could influence tunnel widening. The lower stiffness of the fixation devices is probably responsible of the tunnel widening through the fixation devices's micromotions in the femoral and tibial tunnels.

Ultrasound scanning in infants with biliary atresia: the different implications of biliary tract features and liver echostructure.

OBJECTIVE: To evaluate ultrasonographic features of the liver and biliary tree, including the presence of the triangular cord, in infants with biliary atresia and to analyze the correspondence between hepatic echostructure and histological aspects of the liver. MATERIALS AND METHODS: 35 consecutive infants (19 males) with documented diagnosis of biliary atresia were included. Ultrasonography evaluation, performed at a mean age of 63.1 ± 34.9 days, was focused on the extrahepatic bile ducts, characteristics of the gallbladder and liver, and the presence of the triangular cord. Liver biopsies were examined with particular regard to the presence and severity of fibrosis. RESULTS: On ultrasound, the gallbladder was not seen in 11 (31 %) cases, while in the remaining 24 patients the gallbladder was regular in 6 patients and irregular in 18 cases. The triangular cord was identified in 9 (26 %) of 35 patients. In 21 patients the liver echostructure appeared normal, while in 14 infants the liver parenchyma was more echogenic and coarse than normal. Liver biopsy showed signs of cirrhosis or fibrosis in all cases, including patients with a normal hepatic echostructure. CONCLUSION: Although the triangular cord was visualized in one-fourth of the infants with biliary atresia, abnormalities of the gallbladder on ultrasound (absence or abnormalities of length/shape) were detected in 83 % of the patients. Therefore, ultrasound evaluation of the liver and biliary tree plays an important role in suspecting biliary atresia. On the other hand, a low correspondence between liver echostructure aspects and the presence and severity of fibrosis at liver biopsy was identified. Therefore, severe liver disease in infants with biliary atresia cannot be excluded only on the basis of ultrasound findings.

Accuracy of manual instrumentation of tibial cutting guide in total knee arthroplasty.

PURPOSE: The aim of this study was to evaluate the accuracy of conventional instrumentation for tibial resection in total knee arthroplasty (TKA) as assessed by a computer-based navigation system during each phase of the surgical procedure. The hypothesis is that conventional instrumentation fails to achieve optimal accuracy in final implant positioning, thus leading to surgical errors. METHODS: Forty primary TKAs were performed. The resection guide was placed using an extramedullary guide. Accurate guide positioning was assessed by the navigation system prior to the osteotomy. The alignment measurement was repeated after resection and after component implantation in order to quantify the deviation caused by the manual positioning of the prosthetic components. A deviation ≥2° was considered unsatisfactory. RESULTS: In the frontal plane, unsatisfactory results observed were as follows: 15 % with reference to manual positioning of the resection guide and 10 % with reference to definition of the resection plane with a tendency towards varus malalignment. In the sagittal plane, unsatisfactory results were as follows: 45 % with reference to manual positioning of the resection guide and 40 % with reference to definition of the resection plane with a trend of decreased tibial slope angle. The deviation between bone resection and subsequent implant placement was ≥2° in none of the cases. CONCLUSIONS: The study confirms the hypothesis that conventional instrumentation fails to achieve optimal accuracy in the positioning of the tibial component. During each phase of the surgical procedure, a tendency towards varus malalignment and a decreased tibial slope angle were observed. LEVELS OF EVIDENCE: II.

Open-wedge high tibial osteotomy: comparison between manual and computer-assisted techniques.

PURPOSE: The purpose of our study was to compare clinical and radiological results of two groups of patients treated for medial compartment osteoarthritis of the knee with either conventional or computer-assisted open-wedge high tibial osteotomy (HTO). Goals of surgical treatment were a correction of the mechanical axis between 2° and 6° of valgus and a modification of posterior tibial slope between -2° and +2°. METHODS: Twenty-four patients (27 knees) affected by varus knee deformity and operated with HTO were prospectively followed-up. They were randomly divided in two groups, A (11 patients, conventional treatment) and B (13 patients, navigated treatment). The American Knee Society Score and the Modified Cincinnati Rating System Questionnaire were used for clinical assessment. All patients were radiologically evaluated with a comparative lower limb weight-bearing digital radiograph, a standard digital anteroposterior, a latero-lateral radiograph of the knee, and a Rosenberg view. RESULTS: Patients were followed-up at a mean of 39 months. Clinical evaluation showed no statistical difference (n.s.) between the two groups. Radiological results showed an 86% reproducibility in achieving a mechanical axis of 182°-186° in group B compared to a 23% in group A (p = 0.0392); furthermore, in group B, we achieved a modification of posterior tibial slope between -2° and +2° in 100% of patients, while in group A, this goal was achieved only in 24% of cases (p = 0.0021). CONCLUSION: High tibial osteotomy with navigator is more accurate and reproducible in the correction of the deformity compared to standard technique. LEVEL OF EVIDENCE: Therapeutic study, Level II.

The pathogenesis of endometrial polyps: a systematic semi-quantitative review.

UNLABELLED: The pathogenesis and natural history of endometrial polyps are not very clear. The objective of this study was to assess the opinions of international medical literature regarding the factors involved in the pathogenesis of endometrial polyps and to organize the results consistently with what is known about endometrial physiology. MATERIALS AND METHODS: A systematic review was carried out with the following search engines: PubMed, OVID, Scopus, SCIELO, and AJOL. Two hundreds forty-six abstracts were selected from the literature; of these abstracts, 58 factors were extracted and set as causative, non-causative, unclear or protective link with endometrial polyps. This relation is described through a correspondence analysis and tested with a main effect hierarchical log-linear model. RESULTS: The log-linear model resulted significant for the correspondence found with the following factors: (i) causative link (ageing, bcl-2 protein, excess weight/obesity, tamoxifen regardless of timing, relationship between estrogen receptors and prog-estinics, unbalanced estrogen therapy, estrogen-like effect, and unbalance between estrogens and progestinics), (ii) protective link (progestinics, antiestrogenic action), (iii) unclear link (menopause, ki-67 protein, angiogenesis, tamoxifen for a short time, tamoxifen for a long time, hormone replacement therapy (HRT), endometritis/inflammation), and (iv) non-causative link (none of the factors specifically). DISCUSSION: Subsequently to a review of the physiology of the endometrium, the onsetting of endometrial polyps was suggested through estrogen-related and non-estrogen related ways; the two ways can overlap. The most implied factors in the development of endometrial polyps are linked with one of these or both ways.

Behaviour of lab parameters and neonatal weight loss in relation to neonatal breathing movements and cord clamping time.

BACKGROUND: To date, delaying cord clamping two to three minutes after birth is considered effective for newborn well-being. This time does not consider the newborn's breathing movements, which may also condition neonate well-being. AIM: To investigate the behaviour of neonatal weight loss and of some umbilical vein lab parameters, in relation to timing of newborn breathing and cord clamping. MATERIALS AND METHODS: Time from birth to cord clamping and time from birth to first cry of the newborn were collected in 87 full-term healthy women. First cry is a sign of effective breathing. Birth weight loss at the first, second, and third day from birth and lab parameters were assessed in relation to: time from birth to cord clamping, time from birth to first cry, and cord clamping before or after the first cry. RESULTS: Partial pressure of carbon dioxide (pCO2) decreased if cord clamping was performed after first cry and increased if first cry occurred after cord clamping, independently from the time elapsed from birth to first cry (p = 0.012). Calcium (Ca(2+)) concentration decreased if cord clamping was performed after the first cry and increased if first cry of the baby after birth was delayed (p = 0.021). Each second of delay from birth to cord clamping resulted in an increase in Cl- concentration (p <0.001). Each second of delay in cord clamping resulted in a reduction in the percentage of weight loss at the first day (p = 0.024), at the second day (p = 0.007), and at the third day (p = 0.028) after birth. CONCLUSIONS: Neonate breathing after birth should induce umbilical vein flow from placenta to lungs, conditioning the reduction of birth weight loss after birth and umbilical lab parameters modifications.

Oral health status in liver transplant Italian children.

AIM: The aim of this study was to assess the oral health status in children submitted to liver transplantation in order to evaluate the need to promote suitable dental caries prevention programmes. MATERIALS AND METHODS: Thirty-eight children submitted to liver transplantation (4-5 years) were selected and their data were compared to those of an age-matched control healthy group of 78 children. Clinical examinations were carried out and X-ray bitewings were taken, in order to record caries prevalence, caries experience, periodontal health and dental enamel defects. A questionnaire investigating demographic and oral health behaviour data was completed by parents. RESULTS: Caries prevalence was 78.9% in the liver transplantation group and 39.7% in the healthy control group. The dmft mean value was 2.26±2.25 in the liver transplantation group and 0.69±1.51 in the healthy group. The difference in the mean dmft between the two groups was statistically significant (p<0.0001). From the elaboration of the data on periodontal health it resulted that 23.7% of the liver transplantation subjects and 48.7% of controls had a healthy periodontal status, respectively; 39.5% of the liver transplantation children and 23.6% of the controls had plaque and calculus. In addition, 44.7% of the liver transplantation patients and 28.2%% of the control subjects showed bleeding on probing. In the liver transplantation subjects there was a higher prevalence (65.8%) of dental enamel defects with respect to the healthy group (21.8%). CONCLUSION: The high prevalence of caries and gingival diseases showed the need to promote specific dental caries prevention programmes in liver transplant children.

Could endometrial cytology be helpful in detecting endometrial malignancies?

This short communication assesses the concordance indexes between hysteroscopic biopsies and endometrial cytology for each endometrial pattern found in a sample of 37 women. Patients underwent endometrial cytology under sonographic guidance. The specimens were obtained with an endocervical brush and were fixed on slides (no liquid-based methods). After endometrial cytology, hysteroscopy with biopsy was performed. The best concordance index was found for endometrial malignancies, suggesting that endometrial cytology is able to detect cancers but not other endometrial diseases, as compared with endometrial hysteroscopic biopsies. Therefore, the overall concordance index suggests a fair concordance between histological and cytological findings. This leads us to conclude that usual endometrial cytology should not be recommended to screen endometrial diseases, but it may be used as an alternative diagnostic tool when hysteroscopic biopsies or other blinded procedures for endometrial sampling are unwanted, because it allows malignancies to be detected as well as hysteroscopic-guided biopsies.

Clinical, functional and radiological results of Achilles tenorraphy surgically treated with mini-open technique.

AIM: The aim of this paper was to report clinical, functional and radiological results of 80 patients surgically treated with a combined mini-open and percutaneous surgical repair as proposed by Kakiuchi. METHODS: All patients were evaluated with a physical examination, evaluation scales, a functional test (Ergo-jump Bosco System), and an ultrasonographic exam along with Power Doppler Ultrasonography (PDU) (S/S). RESULTS: At a mean follow-up of 58 months no cases of rerupture were detected. VISA-A evaluation scale showed an excellent score in 63 patients (78.75%), a good score in 14 patients (17.5%), a fair score in two patients (2.5%), and a poor score in one patient (1.25%). Hannover scale showed an excellent score in 63 patients (78.75%), and a good score in 17 patients (21.25%). Ergo-Jump evaluation showed a 2.07% mean deficit of the affected limb at the Squatting Jump test, a 3.26% mean deficit at the Counter Movement Jump test, and a 0.0062% mean improvement at the Repetitive Jump test. Ultrasonographic exam showed in all cases a satisfactory recovery of the integrity of the operated tendon. The mean AP and LL widths showed a significant increase of 7.13±2.97 mm (+56.1%) and of 4.01±2.36 mm (+43.81%) respectively. According to the modified Öhberg score scale, PDU exam showed a grade +1 in 16 patients (20%) and a grade +2 in seven cases (8.7%). CONCLUSION: The absence of rerupture cases, the satisfactory functional and ultrasonographic results of the patients included in this study cause us to consider this technique as reliable and effective even in young high-demand patients.

Effect of epidural analgesia on labor times and mode of delivery: a prospective study.

PURPOSE: To assess changes in labor times and delivery outcome in low-risk women requesting pain relief and undergoing epidural analgesia, according to the epidural analgesia schemes. MATERIALS AND METHODS: Prospective observational study of 499 low-risk women with epidural analgesia. Speed of dilatation (SD) (centimeters of dilatation / hours), speed of lowering of the fetal head through maternal pelvis (SL) (centimeters in lowering / hours), time of active phase of labor (TA), cesarean section (CS), vacuum application (VA) were dependent variables in multivariable linear and logistic regressions. RESULTS: Dilution of ropivacain, fentanyl amount, and volume of the first dose of epidural analgesia did not seem to affect labor times. Epidural analgesia with schemes used in this study favored both the dilatation and the fetal head lowering through maternal pelvis. Every five minutes from the first dose of epidural to the last top-up, SD decreased by about 13% (p=0.002), SL decreased by about 14% (p<0.001), and TA increased by about 40% (p<0.001). Additionally, every five minutes from the first dose of epidural to the last top-up, the odds of an operative vaginal birth (vacuum) increased by 0.7% (p<0.001). Increasing of number of top-ups independently caused a reduction in odds of undergoing CS (odds ratio 0.434; C.I. 95% 0.219-0.859, p=0.017), without influencing labor times. CONCLUSION: Epidural analgesia in patients requesting pain relief favors normal course of labor if it is not discontinued or delayed.

Pain and breastfeeding: a prospective observational study.

OBJECTIVE: To demonstrate that pain affects the goodness of breastfeeding. MATERIALS AND METHODS: Seventy-nine patients were interviewed regarding satisfaction in breastfeeding, tiredness, uterine pain, nipple and other pain, and analgesic use at day three and at first, second, third, and fourth week after birth. Data regarding the mode of delivery were recorded from medical charts. Milk formula supplements, bottle use, pacifier use, and nipple shields use were considered as variables suggesting unsuccessful breastfeeding. RESULTS: At third day after delivery, it appeared that analgesic use was significantly associated with milk formula supplementing, bottle use, less satisfaction in breastfeeding, and more tiredness. At first week after delivery, the presence of pain differing from nipple and uterine pain, was more likely associated with milk formula supplementing, bottle use, pacifier use, less satisfaction in breastfeeding, and more tiredness. At third week after delivery, nipple pain was directly related to tiredness, while it increased the odds of adding milk formula and using a bottle. CONCLUSION: Pain affects the goodness of breastfeeding.
