Abstract
INTRODUCTION Abdominal cocoon syndrome (ACS), or sclerosing encapsulating peritonitis (SEP) is a rare cause of intestinal obstruction in which the bowel and internal abdominal organs are wrapped with a fibrocollagenous cocoon-like encapsulating membrane. While cocooning of the abdomen primarily manifests in individuals undergoing peritoneal dialysis (PD), it has also been reported to occur spontaneously. Remarkably rare, SEP may present with complete mechanical bowel obstruction in select cases. CASE PRESENTATION We hereby report a case of an 87-year-old female patient with a prior history of abdominal surgery, who presented to our emergency department with a clinical picture of complete small bowel obstruction. Clinical and radiological data were suggestive of a strangulated midline hernia, prompting a therapeutic laparotomy. The surgical exploration revealed the encasement of the small bowel loops within a thick fibrocollagenous membrane. Efficient resolution was achieved through skillful adhesiolysis and the meticulous excision of the fibrocollagenous membrane. DISCUSSION SEP is more prevalent in men, with a higher incidence observed in tropical and subtropical countries. While the precise pathophysiology remains elusive, it is hypothesized that subclinical intraabdominal inflammation gives rise to the formation of a dense fibrocollagenous membrane. This membrane encapsulates intraperitoneal organs, ultimately leading to intestinal obstruction. Patients typically present with a recurrent history of small bowel obstruction, notably in the absence of prior abdominal surgery. Abdominal CT scan with experienced radiologist interpretation can aid in preoperative diagnosis. In cases where non-operative management fails and recurrent obstructions persist, surgical adhesiolysis stands as the well-established gold standard. CONCLUSION SEP is a rare abdominal disease, posing challenges for preoperative diagnosis. Laparotomy plays an important role in its diagnosis and treatment. The primary objective of the surgical intervention is to release the encapsulation of the bowel and safeguard the optimal functioning of the small intestines as much as possible.

Abstract
Background: Single incision laparoscopic surgery (SILS) is expanding, enhancing the advantages of multi-port laparoscopic surgery (MLS). Limited literature exists regarding SILS total/subtotal colectomies for inflammatory bowel disease (IBD). Aim of the study was to present the initial experience with this type of approach in a district general hospital and extrapolate its feasibility and safety in this specific context based on gold standard outcomes reported in literature. Materials and Methods: Preoperative parameters, operative details and surgical outcomes of consecutive patients who underwent colonic SILS for IBD in a 5-year period were reviewed retrospectively. Median length of follow-up was 26 months. Results: Fourteen patients underwent SILS subtotal/total colectomy. Median body mass index was 25 (18.1-35). Two patients had previous abdominal surgeries. Median operating time was 202.5 minutes. Two cases were converted to open. Median length of stay was 5 days. Three patients presented complications. Three patients developed parastomal hernias (21.4%). Five out of 12 patients with ulcerative colitis declined further surgery, 3 are awaiting laparoscopic/SILS pouch formation, 1 underwent SILS pouch formation, 1 SILS ileo-rectal anastomosis and 1 patient had SILS completion proctectomy. One patient was not followed up. Conclusions: Despite literature data heterogeneity, these results provide support to the feasibility and applicability of SILS in the subgroup of patients who undergo subtotal/total colectomies for IBD, offering the option for subsequent SILS completion or restorative procedures. Further studies are required to explore the benefit of SILS over MLS (including cosmesis and quality of life) and non-inferiority of SILS regarding the parastomal hernia issue and the operative duration.

Abstract
OBJECTIVE To assess the relation between the ureteral length and the patients' size. PATIENTS AND METHOD Prospective study made between September 2012 and May 2014, on 87 patients with 42 men and 45 women, in whom the ureteral measure was performed during the various procedures that require the use of a pigtail stent. The average age of the population was 53 years old (±15.9) with an average height of 168.3cm (±8.4). This has been achieved through ureteral catheter combining fluoroscopy and endoscopy. RESULTS The ureteral average length was 23.5cm (±2.33). The ureteral average length was 23.8cm (±2.18) for man and 23.2cm (±2.44) for women. In this population, there were a positive correlation between the size of the patients and the length of the ureters (r=0.75; P=0.01). However, this correlation was not found in all subgroups, particularly among women (r=0.16; P=0.30) and on the right side of men (r=0.34; P=0.12). This correlation was still true for the left side in the men's group (r=0.50; P=0.02). CONCLUSION In this study, there is a positive correlation between the patients' size and the ureteral length. But this correlation is not found in some subgroups. It is better to perform in vivo the ureteral measurement to have the precise length in order to set up a pigtail stent adapted to the patient.

Abstract
SummaryFibrinogen plays an integral part in ADP-induced platelet aggregation. Controversy exists in regard to the role of the carboxy termini of fibrinogen Aa chains in this reaction. We have attempted to clarify this problem in view of the availability of a highly purified FII fibrinogen fraction. Kabi fibrinogen or its purified fractions FI, FII and FIII-IV-V were added to washed platelets in the presence of Tyrode-HEPES buffer pH 7.4. Aggregation was initiated by the addition of calcium and ADP. These fibrinogen fractions equally promoted ADP-induced platelet aggregation. The major difference among these fractions is in their Aα chains. The FI fraction contains intact Aα chains while FII and FIH-IV-V fractions have one and two partially degraded Aα chains at the carboxy terminal portion respectively. We conclude that the carboxy terminal portion of the Aα chain does not play an important role in promoting ADP-induced platelet aggregation.

Abstract
In the study of the expression of CatSper genes, consideration of the effects of environmental metal toxicity is very important. Therefore, in this study, the effects of lead acetate and mercury chloride exposure on expression of CatSper genes, sperm parameters, histology of testis and prooxidant antioxidant balance (PAB) values of serum were investigated. A total of 28 mice was divided into four groups. The control group did not receive injections. The sham group received normal saline intraperitoneally. Lead and mercury groups were injected 60 and 1.25 mg/kg/daily lead acetate and mercury chloride respectively intraperitoneally for 2 weeks. After 35 days, the sperm analysis and histology of left testis were performed. In addition, serum was obtained to measure the PAB values. The right testis was used for molecular analysis of real-time PCR. Administration with either lead acetate or mercury caused significant damage to the seminiferous tubules as well as a reduction in sperm parameters compared to the control group. The relative expression of CatSper 1 and CatSper 2 in the lead group was lower than that of the control group (-0.01 ± 0.24, -0.007 ± 0.52 vs. 1 ± 0.50, P = 0.34). The relative expression of CatSper 1 and CatSper 2 was significantly lower in the mercury group compared to the control ones (-0.24 ± 2.28, -4.49 ± 4.86 vs. 1 ± 0.50, P = 0.21). PAB values significantly increased in lead or mercury exposed- mice compared to the control ones (0.93 ± 0.17, 1.54 ± 0.17 vs. 0.51 ± 0.11; P ≤ 0.000). The results of this study showed that administration with either lead acetate or mercury chloride caused degenerative damage in seminiferous tubules and reduction in sperm quality and expression of CatSper 1, 2 genes in mice. Therefore, it is possible in infertile men who have had exposure to lead acetate or mercury chloride. Owing to structural similarities, these metals are substitutes for calcium ions and have effects on calcium channels. These cause immobility in sperm by blocking CatSper-specific calcium channels. However, more studies are required to elucidate the mechanism underlying the impact of different doses of heavy metals on CatSper genes expression.

Abstract
Background: Uterine fibroma was a general gynecologic condition. When pharmacological therapies fail, surgical interferences such as myomectomy, hysterectomy, or embolization of uterine artery (UAE) are used as that state. This study aimed to compare hormone of anti-Mullerian measure among two methods of UAE, myomectomy into the treatment of uterine fibroma. Material and Method: In this clinical trial held in Imam Reza Hospital of Kermanshah, 40 cases by uterine fibroma were entered into the group of UAE (20 cases) and myomectomy (20 cases). Anti-Mullerian hormone levels were measured twice (ago and later therapeutic interventions) using the Monobinal kit. The information are examined by the SPSS (ver. 20.0) software by applying the Leven's test, paired and independent t-test, Wilcoxon, and Mann-Whitney tests. Results: There is n't matter variation in terms of age between two groups (P> 0.05). Not important variation is recognized regarding anti-Mullerian hormone level before and after six months the medical intervention in either group (P> 0.05). Also, no important variation was detected among the 2 groups in terms of the anti-Mullerian hormone level (P= 0.58). Conclusion: The results obtained demonstrated that where is not statistically important variation among UAE and myomectomy by in terms of anti-Mullerian hormone, which reflects ovarian capacity. Therefore, UAE, which is a less invasive method, can be a suitable substitute for surgical methods in the therapy of significant uterine fibroids between women of the sexual period.

Abstract
The central nervous system (CNS) constantly monitors nutrient availability in the body and, in particular, in the gastrointestinal (GI) tract to regulate nutrient and energy homeostasis. Extrinsic parasympathetic and sympathetic nerves are crucial for CNS nutrient sensing in the GI tract. These extrinsic afferent nerves detect the nature and amount of nutrients present in the GI tract and relay the information to the brain, which controls energy intake and expenditure accordingly. Dietary fat and fatty acids are sensed through various direct and indirect mechanisms. These sensing processes involve the binding of fatty acids to specific G protein-coupled receptors expressed either on the afferent nerve fibres or on the surface of enteroendocrine cells that release gut peptides, which themselves can modulate afferent nerve activity through their cognate receptors or have endocrine effects directly on the brain. Further dietary fat sensing mechanisms that are related to enterocyte fat handling and metabolism involve the release of several possible chemical mediators such as fatty acid ethanolamides or apolipoprotein A-IV. We here present evidence for yet another mechanism that may be based on ketone bodies resulting from enterocyte oxidation of dietary fat-derived fatty acids. The presently available evidence suggests that sympathetic rather than vagal afferents are involved, but further experiments are necessary to critically examine this concept.

Abstract
Chronic exposure to a diet rich in fats changes the gastrointestinal milieu and alters responses to several signals involved in the control of food intake. Oleoylethanolamide (OEA) is a gut-derived satiety signal released from enterocytes upon the ingestion of dietary fats. The anorexigenic effect of OEA, which requires intestinal PPAR-alpha receptors and is supposedly mediated by vagal afferents, is associated with the induction of c-fos in several brain areas involved in the control of food intake, such as the nucleus of the solitary tract (NST) and the hypothalamic paraventricular (PVN) and supraoptic nuclei (SON). In the present study we investigated whether the exposure to a high fat diet (HFD) alters the hindbrain and hypothalamic responses to OEA. To this purpose we evaluated the effects of OEA at a dose that reliably inhibits eating (10mg/kg i.p.) on the induction of c-fos in the NST, area postrema (AP), PVN and SON in rats maintained either on standard chow or a HFD. We performed a detailed analysis of the different NST subnuclei activated by i.p. OEA and found that peripheral OEA strongly activates c-fos expression in the AP, NST and in the hypothalamus of both chow and HFD fed rats. The extent of c-fos expression was, however, markedly different between the two groups of rats, with a weaker activation of selected NST subnuclei and stronger activation of the PVN in HFD-fed than in chow-fed rats. HFD-fed rats were also more sensitive to the immediate hypophagic action of OEA than chow-fed rats. These effects may be due to a decreased sensitivity of vagal afferent fibers that might mediate OEA's actions on the brain and/or an altered sensitivity of brain structures to OEA.

Abstract
BACKGROUND Based on WHO reports, smoking is an epidemic in developing countries. One of important issues about this behavior is its distribution pattern in family members. The main purpose of this study was to evaluate if cigarette smoking had a tendency to cluster or aggregate in the families and what the determinants were. METHODS Using a multi-stage random cluster sampling approach, a household survey was conducted in Kish Island in 2009. We used the Alternating Logistic Regressions algorithm to model to show the familial aggregation. RESULTS The odds ratio for the aggregation of cigarette smoking between family members was 1.63 (1.29-2.06) which increased to 1.96 (1.50-2.55) after adjustment for demographic factors. There was no significant correlation between siblings' cigarette smoking nor was between spouses but the pairwise odds ratio for parents offspring was significant. In other words, cigarette smoking in at least one of the parents increased the odds of being a smoker in offspring significantly. CONCLUSION The study showed that the smoking behavior aggregated in families significantly. The inter-parent offspring aggregation was the main component of the familial aggregation. Higher education and age-gender interaction were determinants of smoking in the families. The programs for prevention and cessation of this behavior in the community might be more successful if they were designed in a family-based rather than an individual-based approach.

Abstract
The aim of this study was to examine the effectiveness of group reminiscence therapy on depression symptoms among elderly people attending a day centre in Shiraz, Islamic Republic of Iran. A sample of 49 people aged 60+ years participated in 6 group reminiscence sessions that were held twice weekly for a 3-week period and completed a Farsi version of the 15-item geriatric depression scale. Mean depression scores decreased significantly from 8.18 (SD 1.20) before the intervention to 6.73 (SD 1.20) immediately after it and 7.55 (SD 1.19) 1 month after the intervention. When analysed by demographic characteristics only marital status showed a statistically significant difference in depression scores comparing before and after the intervention.

Abstract
BACKGROUND/AIMS To evaluate the treatment course of patients with primary rhegmatogenous retinal detachment (RRD) that re-detach after initial retinal detachment surgery. METHODS Patients were divided into three groups based on initial surgical treatment: scleral buckle procedure (SBP) (63 eyes), pars plana vitrectomy (PPV) (88 eyes) and combined SBP/PPV (135 eyes). Charts were reviewed for a mean follow-up of 12 months. RESULTS Average number of secondary procedures to achieve anatomical success was lowest in the SBP group (1.1), compared with the PPV group (1.47) and the SBP/PPV group (1.5) (p<0.05). Patients that re-detached after initial PPV/SBP, PPV or SBP required silicone oil injection in 83%, 60% and 22% of the cases and had final best-corrected visual acuity better than or equal to 20/50 in 21%, 33% and 45% of the cases, respectively. Phakic patients that re-detached after initial treatment with PPV/SBP, PPV and SBP required pars plana lensectomy (PPL) in 42%, 25% and 12.5% of the cases, respectively. CONCLUSION Patients with primary RRD that re-detach after initial treatment with SBP require fewer number of secondary operations and silicone oil injections, show a trend for better visual outcomes and are less likely to develop dense cataract or to require PPL compared to patients that re-detach after initial PPV or PPV/SBP.

Abstract
Skeletal muscle fibers form in overlapping, but distinct phases that depend on the generation of temporally different lineages of myogenic cells. During primary myogenesis (E10.5-E12.5 in the mouse), embryonic myoblasts fuse homotypically to generate primary fibers, whereas during later development (E14.5-E17.5), fetal myoblasts differentiate into secondary fibers. How these myogenic waves are regulated remains largely unknown. Studies have been hampered by the lack of markers which would distinguish embryonic from fetal myoblast populations. We show here that the homeobox gene Arx is strongly expressed in differentiating embryonic muscle, downstream of myogenic basic helix-loop-helix (bHLH) genes. Its expression progressively decreases during development. When overexpressed in the C2C12 myogenic cell line, Arx enhances differentiation. Accordingly, it stimulates the transcriptional activity from the Myogenin promoter and from multimerized E-boxes when co-expressed with MyoD and Mef2C in CH310T1/2. Furthermore, Arx co-immunoprecipitates with Mef2C, suggesting that it participates in the transcriptional regulatory network acting in embryonic muscle. Finally, embryonic myoblasts isolated from Arx-deficient embryos show a delayed differentiation in vivo together with an enhanced clonogenic capacity in vitro. We propose here that Arx acts as a novel positive regulator of embryonic myogenesis by synergizing with Mef2C and MyoD and by establishing an activating loop with Myogenin.

Abstract
Oxidative modification of cellular components may contribute to tissue dysfunction during aging. In skeletal muscle, contractile activity increases the generation of reactive oxygen and nitrogen species (ROS). The question of whether contraction-induced ROS generation is further increased in skeletal muscle of the elderly is important since this influences recommendations on their exercise participation. Three different approaches were used to examine whether aging influences contraction-induced ROS generation. Hind limb muscles of adult and old mice underwent a 15-min period of isometric contractions and we examined ROS generation by isolated skeletal muscle mitochondria, ROS release into the muscle extracellular fluid using microdialysis techniques, and the muscle glutathione and protein thiol contents. Resting skeletal muscle of old mice compared with adult mice showed increased ROS release from isolated mitochondria, but no changes in the extracellular levels of superoxide, nitric oxide, hydrogen peroxide, hydroxyl radical activity or muscle glutathione and protein thiol contents. Skeletal muscle mitochondria isolated from both adult and old mice after contractile activity showed significant increases in hydrogen peroxide release compared with pre-contraction values. Contractions increased extracellular hydroxyl radical activity in adult and old mice, but had no significant effect on extracellular hydrogen peroxide or nitric oxide in either group. In adult mice only, contractile activity increased the skeletal muscle release of superoxide. A similar decrease in muscle glutathione and protein thiol contents was seen in adult and old mice following contractions. Thus, contractile activity increased skeletal muscle ROS generation in both adult and old mice with no evidence for an age-related exacerbation of ROS generation.

Abstract
A number of transcription factors have been implicated in the development of the hypothalamo-neurohypophysial system (HNS). Null mutations for these factors caused severe defects in proliferation, migration and survival during early embryogenesis. While they have informed about early events of HNS developments no insights in mechanisms of late development and maturation of this major peptidergic system have been obtained as yet. In a screen for adult-expressed homeobox genes we identified Uncx4.1 as a gene expressed in adult and embryonic magnocellular neurons of the (HNS). Null mutation of Uncx4.1 left these neurons viable and able to express neuropeptides. However, the connectivity of magnocellular neurons with posterior pituitary elements was compromised. As a consequence neuronal fibres traversed to the adenohypophysis. The penetrance of this phenotype was about 50%. The data show a selective role of Uncx4.1 in controlling the development of connections of hypothalamic neurons to pituitary elements, allowing central neurons to reach the peripheral blood circulation and to deliver hormones for control of peripheral functions.

Abstract
Rich diet and lack of exercise are causing a surge in obesity, insulin resistance and steatosis, which can evolve into steatohepatitis. Steatosis and nonalcoholic steatohepatitis (NASH) can also be induced by drugs such as amiodarone, tamoxifen and some antiretroviral drugs. There is growing evidence that mitochondrial dysfunction, and more specifically respiratory chain deficiency, plays a role in the pathophysiology of NASH whatever its initial cause. In contrast, the B-oxidation of fatty acids can be either increased (as in insulin resistance-associated NASH) or decreased (as in drug-induced NASH). However, in both circumstances, the generation of reactive oxygen species (ROS) by the damaged respiratory chain is augmented, as components of this chain are over-reduced by electrons, which then abnormally react with oxygen to form increased amounts of ROS. Concomitantly, ROS oxidize fat deposits to release lipid peroxidation products that have detrimental effects on hepatocytes and other hepatic cells. In hepatocytes, ROS and lipid peroxidation products further impair the respiratory chain, either directly or indirectly through oxidative damage to the mitochondrial genome. This, in turn, leads to the generation of more ROS and a vicious cycle ensues. Mitochondrial dysfunction can also lead to apoptosis or necrosis depending on the energy status of the cell. ROS and lipid peroxidation products also activate stellate cells, thus resulting in fibrosis. Finally, ROS and lipid peroxidation increase the generation of several cytokines (TNF-alpha, TGF-B, Fas ligand) that play sundry roles in the pathogenesis of NASH. Recent investigations have shown that some genetic polymorphisms can significantly increase the risk of steatohepatitis and that several drugs can prevent or even reverse NASH. For the next decade, reducing the incidence of NASH will be a major challenge for hepatologists.

Abstract
OBJECTIVES Phyllodes tumors of the breast (PTB) are rare fibro epithelial tumors. Their terminology, histological classification and their treatment are exposed to controversy. The aim of our work is to underline the epidemiological, clinical, histological, therapeutical, prognostic and evolutive features of these tumours through a retrospective study and a review of the literature. PATIENTS AND METHODS We reviewed at the National Institute of Oncology of Rabat, Morocco, between 1985 and 1998, all the files of patients with histological certainty of PTB, doubtful PTB were excluded. We collected epidemiological, clinical, histological, therapeutical, prognostic and evolutive features of these tumours. STATISTICS quantitative parameters were represented by mean +/- S.D. and qualitative parameters by percentage or effective. RESULTS We studied nine cases of PTB, which represented 0.09% of all primitive tumors of the breast treated at our institution during the study period. All our patients were female. Mean age was 37.3 +/- 10.07 years. Two of our patients (22.2%) had a history of fibroadenoma and 44.4% were nulliparous. Mean delay before consulting was 60.7 +/- 17.56 months and the median tumour size was 13 +/- 7.47 cm. Pathological findings were six benign or borderline phyllodes tumours (66.7%) and three cystosarcomas phyllodes (33.3%). The treatment consisted in simple mastectomy in seven cases (77.8%) and tumorectomy in two cases (22.2%). All the surgical margins were clear. Two of the three cystosarcomas phyllodes received adjuvant external bean radiation therapy 50 Gy on the thoracic chest wall. After a median outcome of 3 +/- 2 years ranging from 3 to 74 months, we did not note any relapse or metastasis. DISCUSSION AND CONCLUSION In our series, PTB happened exclusively in females. History of fibroadenoma within 22.2% of the patients suggests the hypothesis of a filiation between these two entities. Their distinctive features were young age in diagnosis, long delay before consulting, important tumor size, predominant benign and borderline histological types, treatment mainly surgical and good local and distant control.

Abstract
Brain metastases from cervical cancer are extremely rare. We report on two patients who developed cerebellous metastases following uterine cervical cancer. The interval between diagnosis of the primary cancer and diagnosis of brain metastasis was 8 months. The main complaint was symptoms of increased intracranial pressure and cerebellous syndrome. Surgical excision of the brain lesion followed by radiation therapy was performed in the first case. The second patient received palliative radiation therapy. The first patient died 8 months after diagnosis. The second patient is alive 2 months after diagnosis.

Abstract
Angiocentric lymphoma of the face is a rare malignancy. During 11 years, only two patients were treated for a lymphoma of the face. The first patient, 31-year-old, had an angiocentric lymphoma of the nasal cavity, the second patient, 40-year-old, had an angiocentric lymphoma of the nasopharynx and the maxillary sinuses, with an extension the hard palate. According to the Ann Arbor classification, the disease was stage IEab and stage IIEbb, respectively. The first patient was treated by chemotherapy alone (COP regimen) and the second patient underwent combined chemotherapy (CHOP) and radiotherapy. The follow-up was marked by progression of the disease 7 and 9 months after the end of the treatment in the two cases. For the angiocentric lymphoma, treatment based on radiotherapy or chemotherapy alone or combined does not often provide local control and the overall survival rate does not exceed 40% at 5 years.

Abstract
We report the case of a 50-year-old woman presenting a primitive adenoid cystic carcinoma of the middle part of skull base diagnosed by transphenoidal biopsy. She was treated by exclusive radiation therapy with cobalt 60 1.25 MeV and the dose received was 66 Gy in 33 fractions. Our patient remains alive 50 months after the completion of treatment. Adenoid cystic carcinoma is a slow growing malignant tumor with perineural invasion which arises more frequently from salivary glands. The occurrence of primary intracranial adenoid cystic carcinoma is exceptional. The best treatment is radical surgery followed by radiotherapy. Chemotherapy is rarely used. Prognosis is worse than for salivary glands.

Abstract
Based on the series expansion formalism, a relatively simple approach is proposed to solve the eigenvalues problems with partially screened and screened exponential-cosine Coulomb potentials. This approach is used to derive solutions to the Schrödinger equation with the two forms of potentials. The eigenenergies are explicitly deduced from solving the obtained corresponding polynomial equations. For illustration, high accuracy results have been obtained in the entire range of parameter values of these potential forms, with no constraints or adjustable constants. The present approach compares well, with existing methods, the results of which are precisely recovered as particular cases and does allow solutions to eigenvalues problems with any combination of potential parameters.

Abstract
Primary squamous cell carcinoma of the breast is a rare neoplasma included in metaplastic breast cancer. The histogenesis remains unknown. Clinical and radiological appearances are not specific. Nodal involvement is rare and hormones receptors are negative. The treatment is based on surgery associated to radiation therapy and chemotherapy. Prognosis seems to be similar to others breast carcinoma. We report three cases of primary squamous cell carcinoma of the breast recruited at National Institute of Oncology with review of the literature.

Abstract
Primary adenocarcinoma of the male urethra is very uncommon, accounts for 5% of primary urethral cancers. All types of urethral carcinomas account for less than 1% of urinary malignancies in man. The prognosis remains poor despite the wide surgical treatment. The place of chemotherapy combined with radiotherapy must be defined by other studies. We report a case of primary locally advanced adenocarcinoma arising in the bulbo-membranous urethra. The patient was 29 years old, without any previous history of venerian disease. He was treated by combined external beam radiotherapy (total dose 67Gy) and chemotherapy (Cisplatinum). A marked reduction of tumor volume has been noted but the patient died because of the appearance of bone metastasis which failed to the systemic therapy.

Abstract
Non-dysraphic spinal cord lipomas are rare benign lesions, accounting for approximately 1% of all spinal cord tumors. Patients usually present with long histories of disability followed by rapid progression of their symptoms. Presenting symptoms include spinal pain, dysesthesic sensory changes, gait difficulties, weakness, and incontinence. Magnetic resonance imaging is the examination of choice. The T1- and T2-weighted images show increased and decreased signal intensity, respectively. The goal of intervention is decompression and generous debulking following by duraplasty. Early diagnosis of spinal cord lipomas and early surgery is advanced prior to irreversible disease progression. One new case of true non-dysraphic cervicodorsal spinal cord lipoma is reported.
