Primary breast lymphoma: a case series and review of the literature.

BACKGROUND: Primary breast lymphoma (PBL) is a very rare form of non-Hodgkin's lymphoma (NHL), defined as a malignant primary lymphoma occurring in the breast in the absence of previously detected lymphoma localizations. Our study aims to retrospectively evaluate the epidemiological, clinical, and imaging findings and therapeutic features of breast lymphomas in patients with primary lymphoma of the breast. MATERIALS AND METHODS: This is a retrospective study including 13 patients with primary non-Hodgkin's lymphoma of the breast treated at the Salah Azaiez Institute of Oncology from 2000 to 2019. This sample includes 1 case of follicular lymphoma, 2 cases of large T-cell lymphoma, and 10 cases of large B-cell lymphoma. RESULTS: Patients included in the study were aged between 17 and 89 years (average age of 52.6 years). All patients were referred because of a lump in the breast, and only one patient consulted with inflammatory signs in the breast. The average clinical size of the tumor was 7.2 cm, with a maximum of 15 cm. Mammography showed an oval mass with circumscribed margins in the majority of cases. Ultrasound showed in most cases a hypoechoic irregular mass or multilobulated mass with irregular margins and hypervascular on color Doppler. Magnetic resonance imaging (MRI) was performed on only three patients and showed a spiculated lesion with polycyclic limits. Eight patients underwent surgery. In our study breast lymphomas involved 10 cases of large B-cell lymphoma, one case of follicular lymphoma, and two cases of large T-cell lymphoma. In this series, 11 patients had localized stages (I + II) at diagnosis, and 2 patients had disseminated stages (stage III) of primary breast lymphoma. Seven patients underwent chemotherapy treatment alone, and five had chemotherapy with radiotherapy. The median follow-up of our patients was 53 months, ranging from 1 to 177 months. Overall survival was 71% at 3 years and 51% at 5 years. CONCLUSION: Primary breast lymphoma is an uncommon type of breast malignancy. The optimal treatment modality is still in question because of the rarity of this disease. However, the use of combination therapy produces the most favorable results. Surgery is not yet recommended.

Mir-21 and Mir-125b as theranostic biomarkers for epithelial ovarian cancer in Tunisian women.

Background: Ovarian cancer (OC) is the third most common cancer in women and the leading cause of death associated with gynecologic tumors. Because this disease is asymptomatic in the early stages, most patients are not diagnosed until the late stages. This highlights the need for the development of diagnostic biomarkers. MicroRNAs (miRNAs), small non-coding RNAs, are currently being explored as potential biomarkers for the early detection of various malignancies in humans. However, their expression and diagnostic value in OC have not been well studied. Materials and Methods: the plasma levels of miR-21, miR-200a, miR-200b, miR-200c, miR-205 and miR-125b were determined in epithelial ovarian cancer (EOC) patients and healthy controls by Reverse Transcription Quantitative Realtime Polymerase Chain Reaction (RT-qPCR). The expression levels of the deregulated microRNAs were analysed according to clinical characteristics. Results: It was found that miR-21 and miR-125b were upregulated in EOC compared with healthy controls. Moreover, decreased miR-125b was associated with resistance to platinum-based chemotherapy. Conclusions: Our data suggest that miR-21 and miR-125b in plasma may serve as potential circulating biomarkers for the early detection of EOC. MiR-125b may also be useful for predicting chemosensitivity in EOC patients.

A renal angiomyolipoma with a challenging presentation: a case report.

INTRODUCTION: Renal angiomyolipoma is considered a benign mesenchymal tumor composed of fat, smooth muscle, and blood vessels. It represents 1-3% of solid renal tumors. Despite this tumor's benignity, it can be aggressive with a locoregional extension. CASE REPORT: A 41-year-old north African caucasian woman consulted with chief complaints of right lower back pain with no hematuria and no urinal sign. Thoracic-abdominopelvic contrast-enhanced computed tomography showed a right inferior polar heterogeneous renal mass complicated with venous thrombus ascending to the right atrium level. The patient underwent radical nephrectomy under extracorporeal circulation and direct supervision of the fatty thrombus at the right atrium level. The postoperative period was uneventful. The final histologic examination was concordant with renal angiomyolipoma. CONCLUSION: Renal angiomyolipoma is the most common benign kidney tumor. Despite its benignity, it can be associated with lethal complications such as hemorrhage, and it can also show signs of local extension mimicking malignant tumors. The cornerstone of the treatment remains surgery.

Breast tuberculosis: a case series.

BACKGROUND AND AIM: Breast tuberculosis is a rare disease, even in endemic areas. The diagnosis can be challenging, as it can mimic breast cancer. We aim to report our experience and discuss diagnoses and management modalities. RESULTS: We encountered twelve cases of breast tuberculosis in our institution from 2004 to 2019. The average age of our Caucasian North African patients was 42 years old (22-63). The classic presentation was a breast lump found in half of the cases. On physical examination, we suspected breast carcinoma in seven patients. The average size of the tumors was 39 mm (15-80 mm). Nine patients had a mammogram. In five cases, there was a suspicious breast mass mimicking a malignant tumor with an average size of 33 mm (25-60 mm). A ultrasonography was performed in 6 cases and revealed a suspicious ill-circumscribed nodule in four patients with an average size of 37.5 mm (10-60 mm). Five patients had a lumpectomy, and seven women underwent drainage of the abscess and the biopsy of its hull. The association of epithelioid cell granulomas and caseous necrosis was mandatory for the histological diagnosis of tuberculosis. All of them had an antitubercular therapy. The median period of follow-up was of 43 months (3-156 months). One patient presented with a recurrent abscess of the breast. CONCLUSION: Our study found that clinical examination and radiological imaging were not specific. Positive cultures for Koch bacillus or histological confirmation are mandatory for the diagnosis. A meta-analysis of the existing cases is needed.

Bleeding complications following peripheral regional anaesthesia in patients treated with anticoagulants or antiplatelet agents: A systematic review.

BACKGROUND: Patients on either antiplatelet or anticoagulant therapy may need procedures performed under peripheral nerve blocks in preference to general anaesthesia techniques. The risk of bleeding associated with peripheral nerve blocks under these circumstances remains unknown. This systematic review evaluates the incidence of bleeding complications following peripheral nerve blocks in patients receiving antiplatelet and/or anticoagulant medication. METHOD: All English, French and Spanish publications on peripheral nerve blocks in patients receiving antiplatelet and/or anticoagulant medication, from 1978 to 2018 from various sources including Pubmed, were reviewed. Publications on neuraxial anaesthesia (spinal or epidural) and eye blocks were excluded. RESULTS: Twenty-four articles were selected, including six observational studies and 18 case reports. Patients received antiplatelet agents only, in 4 studies, anticoagulants only in 14 studies, and both in 6 studies. In the observational studies, 80 bleeding complications (haematoma or minor bleeding at the puncture site) were identified following 9738 peripheral nerve blocks. Amongst case reports, 15 bleeding complications were noted following 50 peripheral nerve blocks. Bleeding complications were reported mostly with lumbar plexus blocks (1 requirement for blood transfusion, 1 catheter embolization, 1 surgical exploration and 1 death). The overall estimate of the incidence of bleeding complications was 0.82% (0.64%-1.0%). CONCLUSION: This systematic review found that bleeding complications following peripheral nerve blocks were rare in patients receiving antiplatelet and/or anticoagulant medication.

Ultrasound assessment of gastric content in the immediate postpartum period: a prospective observational descriptive study.

INTRODUCTION: Pulmonary aspiration of gastric contents in pregnant women undergoing general anesthesia or sedation/analgesia in the peripartum period is a feared complication in obstetric anesthesia. We assessed the changes in antral cross-sectional area (CSA) with ultrasonography in laboring women and in the immediate postpartum period. PATIENTS AND METHODS: In an observational study in a university-affiliated maternity, gastric ultrasonography examinations were performed in non-consecutive laboring women, after epidural analgesia insertion and after childbirth. Assessment of antral CSA, difficulty of performance on a numerical scale, and factors that could influence gastric content were noted. A cut-off value of 381 mm2 was taken for the diagnosis of empty stomach. RESULTS: One hundred women were enrolled in the study. Median antral CSA was 469 mm2 [25th-75th] [324-591] after epidural insertion and 427 mm2 [316-574] after delivery. Antral CSA was ≥ 381 mm2 in 59 of 90 women (65%) after epidural insertion vs. 48 of 100 women (48%) after delivery (P = 0.59). Median variation of antral CSA between two measurements was 36 mm2 [-42 to 114]. Gastric ultrasonography was significantly more difficult to perform during labor than immediately post-delivery (median difficulty score 5 [2-7] vs. 2 [1-4], P < 0.0001). No risk factors (pain, anxiety, diabetes, smoking) were significantly associated with the occurrence of full stomach post-delivery. CONCLUSION: This study demonstrated that 48% of parturients in the immediate postpartum period presented an antral CSA ≥ 381 mm2 , cut-off being accepted for diagnosis of empty stomach and emphasizes the need for re-assessing before any general anesthetic procedure.

The effect of nefopam on lactation after caesarean section: a single-blind randomised trial.

BACKGROUND: Nefopam is a centrally acting analgesic which has a theoretical risk of stopping lactation due to its anticholinergic and dopaminergic effects. The aim of this study was to evaluate the effect of nefopam on lactation and to investigate potential adverse effects on newborns. METHODS: Seventy-two women, scheduled to undergo a caesarean delivery under spinal anaesthesia and wanting to breastfeed, were randomised to one of two groups: nefopam (20mg, six hourly) or paracetamol (1g, six hourly). In both groups, postoperative analgesia was supplemented with ketoprofen (50mg, six hourly) in conjunction with intrathecal morphine 0.1mg. The primary outcome was onset of lactation, estimated by weighing the newborns before and after feeding; by maternal perception of breast fullness and based on serum prolactin concentration 48hours postpartum. Secondary outcomes were neonatal adverse effects evaluated by neurobehavioural score at 12, 24, 48, and 72hours after birth. Statistical analyses were performed using Chi-squared, Fisher exact and Student t tests as appropriate. P<0.05 was considered statistically significant. RESULTS: The difference in the weight of the newborn before and after each feed, maternal perception of breast fullness and serum prolactin did not significantly differ between groups. The volume of artificial milk given to newborns of mothers in the nefopam group on days two and three was significantly greater than for the paracetamol group. Neurobehavioural scores were comparable at each time point. CONCLUSION: Nefopam does not appear to delay the onset of lactation or present any clear risk to the newborn.

[Risks acceptability related to obstetrical epidural analgesia]. / Acceptabilité des risques associés à la mise en place d'une analgésie péridurale obstétricale.

OBJECTIVES: Evaluation of the acceptability of complications related to obstetrical epidural analgesia in two populations, parturients and anesthesiologists. STUDY DESIGN: Prospective, transversal, single center study. MATERIALS AND METHODS: Evaluation of the acceptability of complications associated with obstetric epidural analgesia performed using a questionnaire of six clinical scenarii in two populations: parturients cared at the University maternity of Nancy and anesthesiologists of Lorraine. Patients were interviewed by an anesthesiologist, physicians via Internet. Acceptability was assessed using two tools, the absolute acceptability with a visual analog scale and the relative acceptability obtained by classifying clinical scenario against each other, in ascending order of acceptability. RESULTS: One hundred and forty-six parturients and 87 anesthetists assessed the acceptability of the different scenarios. The three less serious scenarios (hypotension, failure, dural tap) were acceptable for both populations. One case (spinal hematoma) was unacceptable for parturients. Three cases of varying severity (failure, dural tap, plexus injury with sequelae) were judged significantly less acceptable by patients than physicians (5.9 vs. 7.9 [P<0.001], 5.75 vs. 8.1 [P<0.01], 4.1 vs. 5.1 [P=0.035]). Multivariate analysis did not show any predictive factor of acceptability in both populations. CONCLUSION: In this study, the overall acceptability of the inherent complications of epidural analgesia was good in the two populations. It was essentially based on the notion of severity and preventability. A large interindividual variability was observed and a better acceptance by the anesthesiologists.

Neuraxial anesthesia in patients with intracranial hypertension or cerebrospinal fluid shunting systems: what should the anesthetist know?

The management of patients with central nervous system disorders such as brain tumours, hydrocephalus, intracranial hypertension, or subarachnoid hemorrhage has improved in recent years resulting in increased life expectancy. Consequently, the prevalence of patients with increased intracranial pressure or cerebrospinal fluid shunting devices presenting for non-neurological procedures has increased. These patients commonly receive a general anesthetic, as the safety profile of neuraxial anesthesia in this clinical setting remains uncertain. This article reviews literature on neuraxial anesthesia in patients with intracranial hypertension or cerebrospinal fluid shunting systems. It describes current knowledge, exposes and weighs the real benefits and risks of this technique in this setting. It provides several scenarios and anesthetic options to help the practitioner with choosing a tailored approach in this specific population.

[Preoperative cardiac-risk assessment for non-cardiac surgery: The French RICARDO survey]. / Évaluation du Risque CARDiaque de l'Opéré (RICARDO) : enquête nationale auprès des anesthésistes-réanimateurs concernant la prise en charge périopératoire du patient à risque cardiaque.

OBJECTIVES: Professional practice evaluation of anaesthesiologist for high cardiac-risk patient cares in non-cardiac surgery, and assess disparities between results and recommendations. MATERIALS AND METHODS: Since June to September 2011, a self-questionnaire was sent to 5000 anesthesiologist. They were considered to be representative of national anesthesiology practitioner. Different items investigated concerned: demography, preoperative cardiac-risk assessment, modalities of specialized cardiologic advice, per- and postoperative care, and finally knowledge of current recommendations. RESULTS: We collected 1255 questionnaire, that is to say 25% of answers. Men were 73%, 38% were employed by public hospital; 70% worked in a shared operating theatre with a general activity. With regards to preoperative assessment, 85% of anaesthetists referred high cardiac-risk patient to a cardiologist. In only 16% of answer, Lee's score appeared in anaesthesia file to assess perioperative cardiac-risk. Only 61% considered the six necessary items to optimal estimate of cardiac-risk. On the other hand, 91% measured routinely the exercise capacities by interrogation. The most frequently doing exam (49% of anaesthetist) was an electrocardiogram in elderly patient. In 96% of case, beta-blockers were given in premedication if they were usually thought. Clopidogrel was stopped by 62% of anesthetist before surgery. In this case, 38% used another medication to take over from this one. Only 7% considered revascularization in coronary patient who were effectively treated. POISE study was know by 40% of practitioner, and 18% estimated that they have changed their practice. Preoperatively, 21% organized multidisciplinary approach for high-risk patient. During surgery, 63% monitored the ST-segment. In postoperative period for cardiac-risk patient, only 11% prescribed systematically an ECG, a troponin dosage, a postoperative monitoring of ST-segment, a cardiologic advice. In case of moderate troponin elevation, they were 70% to realize at least an ECG and/or an echocardiography. CONCLUSION: This study highlights some difference between current recommendation concerning assessment of cardiac-risk patient in non-cardiac surgery and daily practice of anesthetist, justifying regular update of this one.

Unilateral permanent loss of vision after nefopam administration.

Acute glaucoma angle closure is a rare complication of anaesthesia and multimodal analgesia. However it is a medical emergency, hence any delay in its treatment may have catastrophic consequences. We present a case of postoperative glaucoma, which had evolved to permanent blindness. We also reviewed the French pharmacovigilance database between 1996 and 2006 and found four other cases of acute glaucoma angle closure in postoperative period possibly related to the administration of nefopam.

I.V. APD421 (amisulpride) prevents postoperative nausea and vomiting: a randomized, double-blind, placebo-controlled, multicentre trial.

BACKGROUND: Postoperative nausea and vomiting (PONV) remain significant clinical problems for patients, especially nausea. The D2-antagonist droperidol was popular for prophylaxis until safety concerns limited its use. In early testing, APD421 (amisulpride for i.v. injection), a D2/D3-antagonist, has shown promising antiemetic efficacy at very low doses. We conducted a randomized, double-blind, dose-finding study to investigate APD421 in PONV prophylaxis. METHODS: Adult surgical patients with ≥2 Apfel risk factors for PONV undergoing surgery expected to last ≥1 h and receiving standard inhalation anaesthesia were randomized to receive placebo or one of three doses of APD421 (1, 5, or 20 mg) as a single i.v. administration at anaesthesia induction. The primary endpoint was PONV (vomiting/retching or antiemetic rescue) in the 24 h period after surgery. RESULTS: Two hundred and fifteen patients received study drug, 92% female and 60% with ≥3 risk factors. Groups were well balanced for baseline characteristics and risk factors. The PONV incidence was 37/54 [69%; 90% confidence interval (CI), 57-79%] in the placebo group; 28/58 (48%; 90% CI, 37-60%) with 1 mg APD421 (P=0.048); 20/50 (40%; 90% CI, 28-53%) with 5 mg (P=0.006); and 30/53 (57%; 90% CI, 44-68%) with 20 mg (P>0.1). APD421 at 5 mg also significantly improved vomiting, rescue medication use, and nausea rates. The safety profile of APD421 was similar to that of placebo at all doses, with no significant central nervous system (CNS) or cardiac side-effects. CONCLUSIONS: APD421 given i.v. before surgery is safe and effective at reducing PONV in moderate/high-risk adult surgical patients. The optimal dose tested was 5 mg.
