Surgical procedures near to language related brain regions may cause severe morbidity in relation to speech. Operations performed under local anesthesia and intraoperative cortical mapping may minimize these risks. Six patients with tumors near the Wernicke's area were treated (2 low-grade astrocytomas, 1 ganglioglioma, 1 xanthoastrocytoma, 1 metastasis, 1 glioblastoma). Their clinical presentation consisted of epilepsy (n=4) and dysphasia (n=2). The skin and periosteum were infiltrated with local anesthetic and an ample craniotomy was performed. Cortical stimulation with an unipolar electrode was then carried out with concomitant speech testing (mainly comprehension and sequential speech). After mapping, the best surgical approach aiming to avoid the mapped area was elected. In 5 cases the resection was total and in 1, partial (glioblastoma). There was a transitory (10 days) worsening of the pre-operative deficit in 1 case (glioblastoma). In 3 patients, the speech areas were displaced: posteriorly (n=2) or anteriorly (n=l). Surgical procedures under local anesthesia are safe and may avoid post-operative language disturbances in patients with tumors near to Wernicke's area.

Three-dimensional image reconstruction for preoperative surgical planning and intraoperative navigation for the resection of low-grade gliomas was performed in 20 patients. Thirteen of these surgeries were performed while the patient received a local anesthetic to allow for cortical mapping. Ninety percent of the patients were functionally intact postoperatively. The authors propose that the combination of the three-dimensional image reconstruction and surgical navigation, in conjunction with intraoperative cortical mapping, provides an additional means for surgeons to improve the safety and precision of the procedures.

AbstractFocal chondral or osteochondral lesions of the knee are common lesions involving either the cartilage layers or the cartilage layers and the subchondral bone. Despite their heterogeneous clinical presentation, they are important risk factors for the premature development of osteoarthritis. Therefore, early detection of osteochondral lesions and focal cartilage defects is crucial. In symptomatic (osteo-)chondral lesions, numerous therapeutic strategies, ranging from conservative treatment to surgical procedures such as marrow stimulation, osteochondral autograft transplantation, or autologous chondrocyte implantation are available. Musculoskeletal radiologists should be familiar with these surgical procedures, the evaluation of the postoperative findings as well as the possible complications when interpreting postoperative imaging studies. This review article describes the different surgical approaches to focal osteochondral lesions of the knee with emphasis on postoperative imaging findings and the pitfalls possibly encountered by the radiologist.

Local anesthetics are substances which, by local action groups on the runners, cause loss of reversible a painful sensation, delimited corresponding to the application. They allow small surgery, short in duration and the endoscopic maneuvers. May be useful in soothe teething pain of short duration and in the locking of the nervous disorders in medical care. Local anesthesia is a process useful for the carrying out of surgery and of endoscopic maneuvers, to soothe teething pain in certain conditions, for depriving the temporary structures peripheral nervous control. Reversible locking of the transmission nociceptive, the set of the vegetative and with a local anesthetic at the level of the innervations peripheral nerve, roots and runners, a trunk nervous, around the components of a ganglion or coolant is cefalorahidian practice anesthesia loco-regional. Local anesthetics summary and semi-summary have multiple applications in dentistry, consulting, surgery and obstetrics, constituting "weapons" very useful in the fight against the pain.

Abstract BACKGROUND AND IMPORTANCE Granular cell tumors (GCTs) of the sellar and suprasellar regions are rare tumors that may be managed surgically by multiple strategies. The technical approaches for these tumors have rarely been described in the literature. CLINICAL PRESENTATION We introduce the case of a patient presenting with dizziness and headaches who was found to have a suprasellar and retrochiasmatic mass and eventually underwent surgical resection. We discuss the characteristics of this tumor, and the current state of the literature. Also included are details regarding the surgical approach utilized in this case, and a discussion of the various surgical approaches for this type of tumor. CONCLUSION There are several approaches for the surgical resection of suprasellar GCTs, and the approach utilized may depend on patient and/or surgeon considerations. Patient-specific considerations must be made to ensure maximal safe resection of these lesions.

Abstract Pediatric low-grade gliomas (pLGG) are primarily driven by genetic alterations in the RAS/MAPK pathway, most commonly involving BRAF of NF1. Despite their molecular convergence, pLGG often show unexplained variability in their clinical outcome. To address this, we molecularly characterized a cohort of >1,000 clinically annotated pLGG. 84% of cases harbored a detectable driver mutation. The remaining 16% of patients nonetheless showed RAS/MAPK pathway up-regulation at the RNA level. The clinical presentation and outcome of pLGG appeared highly variable and linked to the alteration type: re-arrangement or SNV. Re-arrangement-driven tumors were diagnosed at a younger age (6.6 versus 10.9 years, p<0.0001), enriched for WHO grade I histology (88% versus 66%, p<0.0001), infrequently progressed (27% versus 46%, p<0.0001), and rarely resulted in death (3 versus 13%, p<0.0001) as compared to SNV-driven tumors. These included the rarest molecular drivers of pLGG, for which we now have the clinicopathologic features of including MYB, MYBL1, FGFR2 fusions, FGFR1-TACC1, FGFR1 SNVs, IDH1 p.R132H, and H3.3 p.K27M. Utilizing this information, we suggest novel risk categories of pLGG that effectively predicted patient outcome. Low-risk tumors progressed infrequently and rarely succumbed to their disease (10-year PFS of 71% and OS of 98%). Intermediate-risk pLGG had a 10-year PFS and OS of 35% and 90%, respectively. High risk pLGG almost invariably progressed (10-year PFS of 0%) and these patients often succumbed to their disease (10-year OS of 41%). These data highlight the biological and clinical differences between pLGG subtypes and offers molecular based risk stratification to these cancers.

Abstract Background Cesarean section delivery is becoming more frequent. Childbirth is an emotion-filled event and the mother needs to bond with her newborn baby as early as possible. Any intervention that leads to improvement in pain relief is worthy of investigation Aim of the Work to assess the efficacy and safety adding ef Epinephrine to lidocaine 2% in dose-related manner 1:200.000 in prolongation of anesthetic effect of lidocaine as a local anesthetic to reduce post; caesarean section pain after general anesthesia. Patients and Methods A total number of 200 women planned for elective caesarean section at Shams University Maternity Hospital Was recruited, 2 groups were randomized with a study group included 100 women received lidocaine 2% and epinephrine in dose-related manner and a control group included 100 women received lidocaine 2% only. Results women who received lidocaine and epinephrine were more satisfied and hadsignificant more time after caesarean section free of pain in comparison to women who received lidocaine only by 120 minutes. Also. adding Of epinephrine helped in decrease in amount of analgesic consumption after caesarean section. Women who received lidocaine and epinephrine started breast feeding and mobilization earlier than women who received lidocaine only. Epinephrine prolonged the action of lidocaine as a local anesthetic, this prolongation of action of local anesthetic had a significant effect in early mobilization and breast feeding and decrease in cost of analgesics. Nobody in our candidate had a post-operative infection, past operative pyrexia, Allergic reactions tar general anesthesia or complications with local anesthesia. Conclusion Adding of epinephrine to local anesthetics (such as lidocaine 2% in dose-related manner 1:200.0000) prolonged anesthetic effect by more than double of its original anesthetic time, This prolongation on anesthetic effect of local anesthesia by epinephrine helps in eariy mobilization; early breast feeding and less hospital duration stays. No complications (local nor systemic) developed with local infiltration of post-caesarean section incision with lidocaine 2% even aficr adding epinephrine in dose-related manner 1:200.000

Background: Tuberculosis is common in our country. It commonly affects the lungs but in up to one third of the cases involve other organs. Abdominal tuberculosis is one of the important extrapulmonary tuberculosis.It has varied presentation, frequently mimicking other common and rare diseases. Materials and Methods:It is a prospective observational study done to see the clinical presentation and treatment outcome of abdominal tuberculosis in medicine, surgery and gastroenterology department Sylhet M A G Osmani Medical College Hospital during Jan 2008-Dec2008. Sample was collected purposively. All patients were undergone detailed history, clinical examination, relevant investigation and follow up till the end of six months anti tubercular chemotherapy.Data recorded in predesigned record form. Statistical analysis was done with SPSS software. All data presented as percentage or mean. Result: From the 50 cases of abdominal TB, 26 (52%) were male and 24 (48%) were female. Male and female ratio was 1.04:1. Here most of the patients were in the age of 21-30 years and mean age was 29.3 years,majority of them were from poor socioeconomic status(18%) had associated pulmonary tuberculosis.The common presentation exhibited by the patients were weight loss (100%), low grade fever (88%), abdominal pain (86%), bowel disturbance (84%), anorexia (80%), nausea and vomiting (70%), abdominal distension (46%), , ascites (42%).Most of the patients were anaemic with raised ESR.Ultrasonography revealed ascites,abdominal lymphadenopathy and thick walled bowel. Colonoscopy found nodularity and ulceration with narrowing. Ascitic fluid was exudative with predominant lymphocyte count. Laparoscopy and laparotomy revealed tubercle on the intestine and the mesentery with thickening and bowel stricture. All the biopsy reports were consistent with tuberculosis. Site of involvement in decreasing frequency were ileocaecal (44%), peritoneal (16%), abdominal lymph node (8%), ascending colon (8%), small bowel (6%),transverse colon (4%), sigmoid colon (2%), rectum (2%), gastric (2%) and duodenal (2%) but multiple site in 6%.The treatment was given as per the WHO guidelines with category I drugs and found- 86% cured with anti TB alone, 4% needed surgery for intestinal obstruction along with anti TB, and 10% drop out from follow up.Conclusion:The clinical presentations of abdominal TB appear not specific for the condition. Thus, careful approach and supportive results are required in order to issue the final diagnosis. If diagnosed early, it can be treated successfully with the conventional anti-TB drugs.
