Epidural Anesthesia for Neuromyelitis Optica in Obstetrics: A Case Report and Literature Review.

Neuromyelitis optica (NMO), also known as Devic disease, poses unique challenges in obstetrical anesthesia, with limited research available. This case report presents the anesthetic management of a 43-year-old gravida 2 para 1 (G2P1) woman with NMO undergoing labor induction at 39 weeks of gestation. Having received uneventful epidural labor analgesia in her first pregnancy, she faced the delicate decision of neuraxial anesthesia in light of her NMO diagnosis, which was made following her initial pregnancy. Collaborative discussions resulted in the choice of labor epidural analgesia, and an indwelling epidural catheter was placed successfully. An unplanned cesarean section with effective epidural supplementation followed. The case highlights the intricacies of balancing pain relief and neurological risks in NMO patients. Existing literature reflects varying perspectives on neuraxial anesthesia in NMO, with reports both supporting and cautioning against its use. The case aligns with the current view that epidural labor analgesia appears safe in NMO, but conclusive recommendations await larger studies. The decision for neuraxial anesthesia in NMO should be individualized, guided by comprehensive pre-anesthetic counseling and ongoing research developments.

Leiomyoma of the uterine round ligament: A case report.

Leiomyomas are common benign tumours that can arise in any anatomical structure containing smooth muscle. Their localization in the uterine round ligament is rare, although leiomyomas are the most frequent tumour of this structure. Leiomyomas present as inguinal, labial or intra-abdominal masses, and are often misdiagnosed as hernias or enlarged lymph nodes. The aim of the present study was to describe a rare case of a large intra-abdominal mesenchymal neoplasm arising from the right round ligament of the uterus. A 51-year-old asymptomatic female patient (gravida 3, para 3) presented herself for a routine gynaecological examination. A transvaginal ultrasound examination revealed a solid heterogeneous mass with a maximum diameter of 9 cm localized at the right parametrial space. Further preoperative evaluation using magnetic resonance imaging revealed that the mass contained solid and cystic components, which was suggestive of a mesenchymal neoplasm with possible involvement of the right ovary. Complete excision of the tumour and total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed via laparotomy under general anaesthesia. The intraoperative findings, frozen section biopsies and final histological examination of the tumour established the diagnosis of an intra-abdominal myoma of the right uterine round ligament. The majority of abdominal round ligament myomas are initially asymptomatic. The role of synchronous imaging examinations, such as ultrasonography and magnetic resonance imaging, in the diagnosis of these lesions is crucial.

Postoperative abdominal free air: How much and when is enough? Report of two cases.

Postoperative intraperitoneal or ectopic free air may occur after abdominal surgery, gynecologic surgery, laparoscopic surgery, or endoscopic procedures and, in rare cases, represent gastrointestinal perforation, requiring emergency laparotomy. Evaluating patients with postoperative signs of bowel perforation may be difficult, especially when day-case laparoscopic or endoscopic surgery is performed, with the patient readily discharged from hospital. Delayed diagnosis of gastrointestinal perforation due to underestimation of postoperative free air is associated with a high morbidity and mortality rate. We report two cases of patients presenting with postoperative free air along with the clinical presentation and management.

Free air after laparoscopic hysterectomy; from sigmoid perforation to upper airway compromise: a case report.

BACKGROUND: Free air after laparoscopic hysterectomy is a common finding; in rare cases, free air represents gastrointestinal perforation, requiring emergency laparotomy. Ectopic air localizations after pneumoperitoneum have been reported in various laparoscopic surgical techniques. Delayed diagnosis of visceral perforation is associated with high mortality rates. CASE PRESENTATION: We present a white Caucasian female in which dysphonia due to air entrapment in the cervical area, pneumomediastinum and pneumothorax, occured afterlaparoscopic hysterectomy. CONCLUSIONS: Upon mobilization of the patient, air from sigmoid perforation moved cephalad. Through the same path, pneumoperitoneum, causes subcutaneous emphysema in the neck and face, pneumomediastinum and pneumothorax.

Severe anaphylactic shock after anesthesia induction: An unusual initial manifestation of Churg-Strauss syndrome.

Churg-Strauss syndrome or eosinophilic granulomatosis with polyangiitits (EGPA) is a rare multisystem disorder. A case of anaphylactic shock after induction of anesthesia, as the initial clinical presentation of Churg-Strauss syndrome in a 15-year-old girl is reported. It is extremely rare to see pediatric patients with previous perioperative anaphylaxis receiving future anesthesia; a multidisciplinary approach including allergist, rheumatologist, anesthesiologist, and surgeon is necessary in order to provide a better future anesthetic plan.

Ischemic postconditioning decreases iNOS gene expression but ischemic preconditioning ameliorates histological injury in a swine model of extended liver resection.

BACKGROUND: Both pre- and postconditioning have been shown to protect the liver parenchyma from ischemia/reperfusion (I/R) injury during hepatectomy by altering the production of NO. However, to date there is no study to compare their effect on the inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS) gene expression, who are the main modulators in the pathway of NO during the acute phase of I/R injury. METHODS: We designed a prospective experimental cohort comprising of three groups (sham group-SG, preconditioning-PrG and postconditioning group-PoG) and consisting of 10 animals per group. All animals underwent extended hepatectomy (70%) under prolonged warm ischemia either after preconditioning or followed by postconditioning or without any protective maneuver (SG). Following reperfusion blood samples and liver biopsies were obtained at the start of reperfusion (0 hours), at 6 and 12 hours post reperfusion. iNOS and eNOS gene expression was assessed on liver tissue by polymerase chain reaction (PCR); in addition, the extent of hepatocellular injury was histologically assessed. RESULTS: At the beginning of reperfusion iNOS expression was significantly reduced in the PoG in comparison to the SG (Kruskal-Wallis test, P=0.012; Mann-Whitney U test, P<0.0005 Bonferroni correction) and continued to remain at low levels until 6 hours post reperfusion (Kruskal-Wallis test, P=0.01; Mann-Whitney U test, P<0.0005-Bonferroni correction) This difference was eliminated by 12 hours. No significant differences were found in the expression of eNOS between groups and within time measurements. Aspartate aminotransferase (AST) and Alkaline phosphatase (ALP) were found increased at the start of reperfusion; their levels continued to increase by 6 hours in all groups, however only in the PoG the increase attended statistical significance at 12 hours after reperfusion. ALT levels presented only minor alterations during the course of reperfusion. The PrG was found to have more intense hepatocellular injury at the start of reperfusion than the PoG however, that appeared to gradually settle by 12 hours in contrast to PoG where the hepatocellular injury continued to deteriorate. CONCLUSIONS: PoG appeared to decrease iNOS overexpression more effectively than PrG in comparison to animals who have undergone no protective maneuver (SG). However, PrG was more effective than PoG in ameliorating the hepatocellular injury observed at 12 hours after the ischemic insult.

Pseudomyxoma Peritonei: Presentation of Two Cases and Challenging Issues in the Literature.

Pseudomyxoma peritonei (PMP) is a rather uncommon syndrome in oncology with a unique biological behavior and an estimated incidence of one to two cases per million per year. Clinically, it usually presents with a variety of unspecific signs and symptoms including abdominal pain and distention, ascites, or even bowel obstruction. Despite its intimidating clinical manifestation, PMP is characterized by satisfactory survival rates when treated with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC). We present two interesting cases of PMP deriving from the appendix with a rather atypical presentation, which was successfully treated with cytoreduction and HIPEC. In addition, we intend to raise clinical suspicion on the diagnosis of PMP and comment on several challenging issues concerning the origin and classification of PMP.

Ropivacaine, Interleukin-6 and Tumor Necrosis Factor Alpha Plasma Levels during Intermittent Epidural and Continuous Wound Infusion of Ropivacaine for Analgesia after Hysterectomy or Myomectomy: An Observational Study.

BACKGROUND/AIMS: The concentration-time profile of the long-acting local anesthetic ropivacaine after epidural (EP) administration at fixed time intervals or continuous subcutaneous (SC) infusion has not been fully evaluated. The objective of this work was to determine total plasma concentrations of ropivacaine and changes in cytokine interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) levels during EP and SC. METHODS: In this prospective randomized controlled trial, 18 patients undergoing abdominal hysterectomy or myomectomy were randomly selected to receive ropivacaine either every 6 h via an EP catheter or by continuous wound infusion along the skin incision, after a bolus dose, for 48 h. Total plasma ropivacaine concentrations were measured before the bolus and 2, 4, 8, 24, 48, and 50 h after the bolus using high-performance liquid chromatography-UV and IL-6 and TNF-α levels were measured at 0, 8 and 24 h with ELISA and analyzed statistically. RESULTS: During EP, mean ± SD ropivacaine concentrations were relatively stable up to 50 h postoperatively, that is, 239 ± 89 ng/ml, while during SC, initial concentrations between 2 and 8 h were comparatively lower (101.5 ± 42.9 ng/ml) than 24-50 h concentrations (437.1 ± 206 ng/ml). An increase in IL-6 levels was noted between 0 and 24 h during EP and SC, but TNF-α levels increased slightly, between 0 and 24 h, only during EP. CONCLUSION: Ropivacaine plasma concentrations with both EP and SC were found to be safe throughout the administration time interval. IL-6 levels increased during the same time interval, while TNF levels varied only slightly.

Clinical presentation and management of gastro-intestinal and pancreatic secondary metastatic tumors.

PURPOSE: As progress regarding the treatment has occurred over recent years in oncology, more patients with metastatic disease are presented for diagnosis and further management. The purpose of this study was to reveal the incidence, location and to describe the clinical characteristics and outcome in a series of patients diagnosed with pancreatic, small and large bowel metastatic tumors that underwent metastasectomy. METHODS: A total of 12 patients (7 male and 5 female) diagnosed with extrahepatic gastrointestinal (GI) and pancreatic metastases from 2001 to 2013 were operated for resection of secondary metastatic tumors to the small and large bowel and the pancreas. Four out of 12 patients were asymptomatic and a secondary tumor was detected during follow up. RESULTS: The median interval revealing the metastatic tumor since the management of the primary tumor was 6.5 years (range 1-27). Primary tumors were malignant melanoma (4 patients), renal cell carcinoma (RCC; 2 patients), leiomyosarcoma of the uterus (2 patients), lobular breast cancer, mesenchymal chondrosarcoma of the skull, endometrial adenocarcinoma and a non-Hodgkin lymphoma (one case each). The median follow-up was 15 months (range 4-120). CONCLUSIONS: Metastatic secondary tumors have to be considered especially when the patient's medical history includes a previous malignancy. They may also occasionally present as the initial manifestation of an occult primary lesion leading to diagnostic difficulty. Although radical surgery is the most effective approach, treatment and survival grossly depend on histological type and the stage of the primary disease. Hence, management of these patients should be individualized by a multidisciplinary team.

Intermittent epidural vs continuous wound infusion of ropivacaine for acute and chronic pain control after hysterectomy or myomectomy: a randomized controlled trial.

OBJECTIVE: Adequate postoperative analgesia may enhance recovery. The efficacy of continuous wound infusion vs intermittent epidural ropivacaine for postoperative analgesia was investigated. DESIGN: Prospective randomized, observer blind trial. SETTING: Aretaieio University Hospital. SUBJECTS: Patients scheduled for open abdominal hysterectomy or myomectomy. METHODS: Patients received 10 mL of 0.75% ropivacaine along the skin incision before skin closure, followed by wound infusion 2 mL/hour of 0.375% ropivacaine or epidurally 10 mL of 0.75% ropivacaine in the beginning of surgery followed by 10 mL of 0.2% ropivacaine 6 hourly. The epidural injections or the wound infusion of ropivacaine lasted 48 hours. Rescue analgesia consisted of patient-controlled analgesia morphine up to 48 hours and acetaminophen/codeine tablets the next 24 hours. Analgesic consumption and visual analog scale pain at rest and during cough were assessed 2, 4, 8, 24, 48, and 72 hours postoperatively. One and three months later, patients were interviewed by phone for analgesic consumption at home and presence of pain. RESULTS: The subcutaneous group consumed more morphine during the first 2, 4, and 8 hours postoperatively (P < 0.001, P < 0.001, and P < 0.001, respectively). Subsequent morphine and acetaminophen/codeine requirements did not differ between the two groups. Pain intensity during cough was higher only 2 hours after surgery in the subcutaneous group (P = 0.002). Three months postoperatively, the two groups did not differ in the analgesic requirements and presence of persisting and/or burning pain. CONCLUSION: Based on our results, there is no clinical significant difference between the epidural ropivacaine and the subcutaneous ropivacaine group or a clear superiority to one management strategy.

Non-functioning pancreatic endocrine tumors: eleven-year experience in a single institute.

PURPOSE: Non-functioning pancreatic endocrine tumors (NF-PETs) comprise the majority of pancreatic endocrine tumors. We present our experience from the management of 18 patients with NF-PET. METHODS: From May 2002 to June 2013, 18 patients were admitted in our hospital for the management of NF-PETs. We analyzed their clinical presentation, preoperative evaluation, surgical and postoperative management and the outcome. RESULTS: The tumor was located in the pancreatic head in 13 (72%) patients and in the body and tail of the pancreas in the remaining 5 (28%). Four patients (22%) had stage IIIa, 7 (39%) stage IIIb and 7 (39%) stage IV. Twelve (67%) patients with pancreatic head tumor underwent pancreatoduodenectomy (PD). In one case (5%), the tumor was deemed unresectable and the remaining 5 (28%) patients underwent distal pancreatectomy and splenectomy (DPSP). Four (22%) patients with unilobar metastatic liver disease underwent hemihepatectomy or segmentectomy. Perioperative mortality was 0%. Postoperatively, all stage IV patients received peptide receptor radionuclide treatment (PRRT). The 5-year overall survival rate was 61%, with a median survival of 71 months, whereas the 5-year overall survival rate after diagnosis of hepatic metastases was 45%. CONCLUSION: Surgical resection is the gold standard for the treatment of NF-PETs. A formal resection appears to be the standard procedure when malignancy is verified or suspected. Aggressive surgery should be undertaken in patients with locally advanced or metastatic NF-PETs, as it may prolong survival. In stage IV patients, intra-arterial PRRT, after super-selective catheterization of the hepatic artery, is a promising therapeutic modality.

Pregabalin vs. opioids for the treatment of neuropathic cancer pain: a prospective, head-to-head, randomized, open-label study.

OBJECTIVES: Neuropathic cancer pain (NCP) is a common manifestation of cancer and/or its treatment. Treatment following the WHO analgesic ladder provides relief for the majority of cancer pain patients; however, concern remains that opioids may be less efficacious for neuropathic pain (NP) compared with nociceptive pain, often necessitating the use of higher doses. Adjuvants, such as pregabalin, have shown to be efficacious for the treatment of NP, although data come mostly from noncancer studies. The comparative efficacy and safety of opioids versus adjuvants has not been studied for NCP. The aim of this study was to directly compare pregabalin versus a strong opioid for the treatment of NCP. METHODS: A total of 120 patients, diagnosed with "definite" NCP, were randomized into two groups and received increasing doses of either oral pregabalin or transdermal fentanyl for 28 days. VAS score, patient satisfaction, need for opioid rescue, and adverse events (AEs) were recorded. RESULTS: In the pregabalin group, a significantly higher proportion of patients achieved at least 30% reduction in VAS compared with the fentanyl group (73.3%, 95% CI: 60.3%-83.93 vs. 36.7%, 95% CI: 24.5%-50.1%, P < 0.0001, respectively), while the percentage mean change from baseline was also significantly different [46% (95% CI: 39.5%-52.8%) for pregabalin and 22% (95% CI: 14.9%-29.5%) for fentanyl (P < 0.0001)]. Patient-reported satisfaction was more frequent with pregabalin, while AEs and treatment discontinuations were more frequent in the fentanyl group. DISCUSSION: Prompt use of a neuropathic pain-specific adjuvant, such as pregabalin, in NCP may lead to better control of the neuropathic component, with opioid-sparing effects.

Neuroendocrine differentiation in embryonal type hepatoblastoma.

Hepatoblastoma, a malignant tumor which arises occasionally in older children but very rarely in adults, exhibits divergent differentiation with embryonal cells, fetal hepatocytes and immature elements. This report describes an embryonal type hepatoblastoma with neuroendocrine differentiation in a 16-year-old patient, which was diagnosed postoperatively. Clinical and radiologic work-up failed to reveal a primary gastrointestinal malignancy and no primary lesions were detected in any other organ. This feature of hepatoblastoma is considered to be a multidirectional differentiation of the small epithelial or stem cells of the liver. At 2-year follow up, the patient remains symptom-free, with normal laboratory and diagnostic imaging studies, and no recurrent or metastatic disease identified.

A multimodal approach to acute biliary pancreatitis during pregnancy: a case series.

The treatment of acute biliary pancreatitis during pregnancy remains controversial. We present our experience of treating 7 pregnant women with acute biliary pancreatitis and verified or suspected choledocholithiasis, by using magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and sphincterotomy followed by laparoscopic cholecystectomy. MRCP was performed in all patients to confirm the presence of common bile duct stones, their size and number. ERCP and sphincterotomy were performed without the use of radiation. The procedure was terminated only when all stones (the number clarified at MRCP), were retrieved into the duodenum. All patients underwent laparoscopic cholecystectomy the following day. Neither post-ERCP nor postoperative major complications were noted. All but one patient reached a healthy natural-term labor. One patient had a planned cesarean section on 35th week. The combination of MRCP, nonradiation ERCP, and immediate laparoscopic cholecystectomy provides definite treatment and seems to put both mother and fetus at lower risk than presumed.

Perioperative pregabalin for acute and chronic pain after abdominal hysterectomy or myomectomy: a randomised controlled trial.

CONTEXT: The antiepileptics gabapentin and pregabalin are used as adjuvants to control postoperative pain. OBJECTIVE: The aim of the present study was to investigate the effect of perioperative administration of pregabalin on postoperative acute and chronic pain and analgesic requirements. SETTING: Department of Anaesthesiology, Aretaieio University Hospital, Athens, Greece. PATIENTS: Eighty patients scheduled for abdominal hysterectomy or myomectomy were randomly assigned to the pregabalin or to the control group. INTERVENTION: The pregabalin group received 150 mg of pregabalin 8-hourly, starting on the afternoon before surgery and continued until the fifth postoperative day. The control group was similarly treated, but received placebo capsules instead. MEASUREMENTS: Postoperative intravenous morphine and Lonalgal (30 mg codeine with 500 mg paracetamol) tablet consumption, visual analogue pain scores at rest and on coughing, sedation, anxiety, dizziness, ataxia, blurred vision and diplopia were recorded. One and 3 months postoperatively patients were interviewed for the presence of pain and analgesic needs due to surgery. RESULTS: The pregabalin-treated patients consumed less morphine during the first 48 h postoperatively (P = 0.0001). However, consumption of Lonalgal tablets and visual analogue scores for pain at rest and on coughing did not differ between the groups. No difference was found in sedation and anxiety scores between the patients who received placebo or pregabalin. Patients in the control group had lower incidences of dizziness (29 versus 58%, P = 0.015), ataxia (0 versus 18%, P = 0.011), blurred vision (6 versus 26%, P = 0.028) and diplopia (0 versus 16%, P = 0.023). Presence of pain, analgesic intake due to surgery and decreased or absent sensation around the wound did not differ between the groups 1 and 3 months postoperatively. CONCLUSION: Pregabalin in the doses given decreased morphine requirements for the first 48 h postoperatively, but neither altered the analgesic requirements beyond 48 h nor had any effect on acute, late or chronic pain.

Two cases of primary splenic hydatid cyst in Greece.

Cystic disease of the spleen is an uncommon entity in general population. Most cases result from parasitic infection by Echinococcus granulosus, a form called splenic hydatid disease (SHD), with a reported frequency of 0.5-6.0% within abdominal hydatidosis. On the contrary, an isolated splenic involvement of hydatid disease is very uncommon even in endemic regions. Two cases of primary SHD managed with open and laparoscopic radical surgery in our department are reported herein. Primary SHD is a rare entity with non-specific symptoms underlying clinical suspicion by the physician for prompt diagnosis. Surgical treatment is the mainstay therapy, while laparoscopic approach when feasible is safe, offering the advantages of laparoscopic surgery.

Seronegative cat-scratch disease diagnosed by PCR detection of Bartonella henselae DNA in lymph node samples.

Cat scratch disease (CSD), the typical clinical manifestation of Bartonella infections usually follows a typical benign self-limited course. Nevertheless, a variety of unusual clinical manifestations and confusing imaging features can lead to misinterpretations and render the disease a diagnostic dispute. Routine laboratory tests exhibit varying reported sensitivity and are usually unhelpful in diagnosis, as serology fails in terms of specificity and/or sensitivity. Herein we report a case of seronegative Bartonella infection presenting as symptomatic suppurative lymphadenitis with abscess formation, which was surgically drained. Diagnosis was established by PCR analysis from lymph nodes samples obtained during the procedure. PCR detection of specific DNA fragments from lymph node biopsy provides a sensitive detection of disease. The technique should be considered for patients with suspected CSD and negative serology, since serological assays exhibit low sensitivity. In ambiguous cases, surgical exploration may provide tissue for diagnosis; it is well tolerated and affords improved recovery.

A common anesthesiology procedure for a patient with an uncommon combination of diseases: a case report.

Administering neuraxial anesthesia to a patient with an underlying neurological disease and a combination of four other pathological disorders can be challenging. We report in this paper the case of a 45-year-old woman with neurological deficit due to ischemic brain infarct, multiple sclerosis, antiphospholipid syndrome, and ß-heterozygous thalassemia that was subjected to abdominal hysterectomy and bilateral salpingoophorectomy under epidural anesthesia for ovarian cancer.
