A rare condition: Ectopic liver tissue with its unique blood supply encountered during laparoscopic cholecystectomy. Int J Surg Case Rep 2015; 9:47-50. [PMID: 25723748 PMCID: PMC4392331 DOI: 10.1016/j.ijscr.2015.02.027] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Revised: 02/11/2015] [Accepted: 02/17/2015] [Indexed: 12/13/2022] Open
Abstract
Developmental abnormalities of liver including ectopic liver are rare conditions. Although it does not usually produce any symptom clinically, it can rarely result in serious complications such as bleeding, pyloric and portal vein obstruction. Ectopic liver has the capacity of malignant transformation to hepatocellular carcinoma that makes it essential to be removed. The vascular anatomy of ectopic liver should be identified before the dissection of gallbladder in order to prevent hemorrhage from the liver parenchyma.
Introduction Developmental abnormalities of liver including ectopic liver tissue (ELT) are rare conditions. Few cases presenting ELT have been reported in literature till now. Even though the most common area seen is gallbladder, it is detected both abdominal and thoracic sites. There is a relationship between HCC and ectopic liver that necessitates the removal. Presentation of case A 51-year-old female was hospitalized because of abdominal pain. Gallstone and bile duct dilatation were determined during ultrasonographic (USG) evaluation. The patient was operated for cholecystectomy following a successful endoscopic retrograde cholangiopancreatography (ERCP). During operation, a mass located on gallbladder with its unique vascular support was identified and resected together with gallbladder. The mass had a separate vascular stalk arising from liver parenchyma substance and it was clipped with laparoscopic staples. The histopathological examination revealed that the mass adherent to gallbladder was ectopic liver confirming the intraoperative observation. The postoperative course of patient was uneventfull and she was discharged at the second day after the operation. Discussion Ectopic liver tissue is incidentally found both in abdominal and thoracic cavity. ELT can rarely be diagnosed before surgical procedures or autopsies. It can be overlooked easily by radiological techniques. Although it does not usually produce any symptom clinically, it can rarely result in serious complications such as bleeding, pyloric and portal vein obstruction. ELT also has the capacity of malignant transformation to hepatocellular carcinoma that makes it essential to be removed. Conclusion Although ELT is rarely seen, it should be removed when recognized in order to prevent the complications and malignant transformation.

Abstract
High level disinfection (HLD) of the gastrointestinal (GI) endoscope is not simply a slogan, but rather is a form of experimental monitoring-based medicine. By definition, GI endoscopy is a semicritical medical device. Hence, such medical devices require major quality assurance for disinfection. And because many of these items are temperature sensitive, low-temperature chemical methods, such as liquid chemical germicide, must be used rather than steam sterilization. In summarizing guidelines for infection prevention and control for GI endoscopy, there are three important steps that must be highlighted: manual washing, HLD with automated endoscope reprocessor, and drying. Strict adherence to current guidelines is required because compared to any other medical device, the GI endoscope is associated with more outbreaks linked to inadequate cleaning or disinfecting during HLD. Both experimental evaluation on the surveillance bacterial cultures and in-use clinical results have shown that, the monitoring of the stringent processes to prevent and control infection is an essential component of the broader strategy to ensure the delivery of safe endoscopy services, because endoscope reprocessing is a multistep procedure involving numerous factors that can interfere with its efficacy. Based on our years of experience in the surveillance of culture monitoring of endoscopic reprocessing, we aim in this study to carefully describe what details require attention in the GI endoscopy disinfection and to share our experience so that patients can be provided with high quality and safe medical practices. Quality management encompasses all aspects of pre- and post-procedural care including the efficiency of the endoscopy unit and reprocessing area, as well as the endoscopic procedure itself.

Abstract
INTRODUCTION Duodenal perforations after endoscopic retrograde cholangiopancreatography (ERCP) are an uncommon complication. The management of this kind of perforation is controversial. The aim of this study was to analyze the results of the management of a series of 15 patients who were diagnosed with this complication. METHODS Retrospective study of duodenal perforations after ERCP diagnosed at a tertiary level hospital, between 2001 and 2011. The variables age, sex, ERCP indication, type of perforation, time of diagnosis, clinical presentation, radiographic findings, management, surgical technique, length of stay and intrahospital mortality were recorded and analyzed. RESULTS Out of a total of 1923 ERCP performed, 15 duodenal perforations were detected (0,78%). Perforation site was the duodenal wall (3 cases) and periampullary (12 cases). Eleven perforations were suspected during the procedure. Patients with duodenal wall perforations underwent immediate surgery. Seven of 12 periampullary perforations were managed conservatively with a favorable outcome in 5 of them. Subsequent scheduled surgery was performed in 4 cases. The mean length of hospital stay was 21,2 days (range: 3-49) and intra-hospital mortality was 20%. CONCLUSIONS Perforations after ERCP have high mortality rates, and require a complicated therapeutic approach that needs to be individualized. Selective conservative management is a valid and safe option in selected patients.

Abstract
In commenting on a case report of a 55-year-old man who suffered Takotsubo syndrome (TTS), in the setting of receiving chemotherapy with cytarabine and daunorubicin for acute myeloid leukemia, the author expresses his views that TTS in the setting of chemotherapy for malignancies may not be chemotherapeutic drug-specific (like in the chemotherapeutic drug induced-cardiomyopathy), but may be due to the emotional and physical stresses resulting from the realization of having diagnosed with a malignancy, and the diagnostic testing, and therapeutic management which follows.

Abstract
OBJECTIVES To understand knowledge of HPV, its association with head and neck cancer (HNC), and source of knowledge in a high-risk population. MATERIALS AND METHODS A cross-sectional survey was conducted among attendees at a Drag Racing event in East St. Louis in 2013. RESULTS Only 29.9% knew that HPV definitely increases the risk of developing HNC, 42.4% thought HPV was same as HIV, and only 25.1% received HPV information from a healthcare practitioner. Participants that thought number of sexual partners did not increase risk of developing HPV were more likely to have low knowledge scores (r=.74, p<.001). There were significant associations between HNC knowledge, number of sexual partners, age at initial coitus, and risk perception; and those who did not think having more sexual partner increases the chance of developing HPV infection were 33times more likely to have lower knowledge of the association between HPV and HNC (OR=33.27; 95% CI: 16.34, 67.74). CONCLUSIONS Knowledge of HPV and its association with head and neck cancer has significant gaps in this population, with a large number of the population accessing HPV information from sources other than a healthcare provider.

Abstract
Background Surgical techniques used in the treatment of patients with high grade lumbar spondylolisthesis (> 50% slippage) are usually associated with a great deal of controversies. We aim to evaluate the surgical outcomes of high grade spondylolisthesis treated with an intraoperative temporary distraction rod. Methods We retrospectively studied 21 patients (14 females and 7 males), aged 50.4 ± 9.2 years, who had high grade lumbar spondylolisthesis that was treated with intraoperative temporary distraction rods, neural decompression, pedicular screw fixation, and posterolateral fusion involving one more intact upper vertebra. The mean follow-up period was 39.2 months. Radiologic and clinical outcomes were measured by slip angle, slip percentage, correction rate, Oswestry Disability Index (ODI), visual analogue scale (VAS), patient's satisfaction rate in the pre- and postoperative period. Data were analyzed by SPSS ver. 11.5. Results Analysis of the preoperative visits and final follow-up visits indicated that surgery could improve ODI, lumbar VAS, and leg VAS from 60.5% to 8.2%, from 6.7 to 2.2, and from 6.9 to 1.3, respectively. Slip angle and slip percentage were also changed from -8° to -15° and from 59.2% to 21.4%, respectively. Mean correction rate at the final follow-up visit was 64.1%. Loss of correction was insignificant and a neurologic complication occurred in one patient due to misplacement of one screw. Excellent and good levels of satisfaction were observed in 90.5% of the patients. Conclusions In the surgical treatment of refractory high grade spondylolisthesis, the use of a temporary distraction rod to reduce the slipped vertebra in combination with neural decompression, posterolateral fusion, and longer instrumentation is associated with satisfactory clinical and radiologic outcomes.

Abstract
Adenoid cystic carcinoma (ACC) of the breast is very rare in males. There have been only eight previous articles published on breast ACC in males. Here, we will report on the first case of this type of tumor in the Chinese province of Hainan. The patient was a 19-year-old male, and he underwent a radical mastectomy (RM) with axillary lymph node dissection. The histopathological examination specimen revealed that surgical margins were negative; none of the 41 axillary lymph nodes excised were positive for malignancy. The patient is alive and well 67 months after radical mastectomy. In the present study, we discuss the diagnosis and treatment options for male breast ACC based on previous English publications.

Abstract
BACKGROUND Tandem occlusive disease in the setting of acute ischemic stroke involving cervical and cerebral arteries has been associated with poor neurological outcome and poses significant challenges to neurointerventionists. Previously described endovascular methods typically involve carotid revascularization with stent placement prior to or following intracranial thrombectomy. Stent-based approaches, however, require the use of antiplatelet therapy which may increase the risk of hemorrhagic transformation. We describe a novel modified Dotter technique which may be used for carotid revascularization in lieu of stenting. This technique can eliminate the need for antiplatelet therapy, reduce procedure times, and possibly reduce hemorrhagic conversion rates. METHODS Seven patients presenting between April 2013 and January 2014 were treated with this technique. All patients had carotid stenosis of 65-100% and tandem middle cerebral artery occlusions. National Institutes of Health (NIH) Stroke Scale scores as well as clinical and procedural times were recorded. Pre- and post-Dotter stenosis was measured using the NASCET criteria. Follow-up imaging and clinical data were reviewed. RESULTS The mean age was 64 years and mean initial NIH Stroke Scale score was 11.7. Mean groin to recanalization time was 26 min. Thrombolysis In Cerebral Infarction grade 2b-3 was achieved in all patients. The mean stenosis was 88% preoperatively and 61% postoperatively. There were no intracranial hemorrhages. The modified Rankin Scale score was 0 in six patients (86%) and 6 in one patient (14%). CONCLUSIONS The Dotter stroke technique is a feasible and safe alternative to carotid stenting in the setting of acute ischemic stroke and may reduce the risk of hemorrhagic conversion. No re-occlusion occurred during follow-up in patients with post-Dotter stenosis ≤65%.

Abstract
Introduction Splenic hamartoma is a primary benign tumor of the spleen, which is often found incidentally. Splenic hamartomas are very rare, with approximately 150 cases documented in the literature to date. They represent benign vascular proliferation. Histological findings consist of disorganized stroma and vascular channels of varying width, with or without lymphoid follicles. Case presentation We present the case of a 39-year-old Greek woman, with no significant medical history, who was diagnosed incidentally with an enormous splenic hamartoma on computed tomography, finally confirmed by surgery and histopathology. Hamartomas are benign lesions, and it is important to differentiate them from malignancy. Conclusion Hamartoma represents a rare vascular entity characterized by a cluster of differentiation 8-positive immunophenotype. It is usually asymptomatic but large hamartomas may present with symptoms such as hemopoetic disorders, which resolve after splenectomy. It is important for radiologists to be able to differentiate splenic hamartoma from malignant entities.

Abstract
Abstract Excessive lordosis is a common finding and may produce mechanical pressure that causes repetitive strains of the interspinous ligament with subsequent degeneration and collapse. Baastrup’s disease (kissing spine syndrome) is a term referring to close approximation of adjacent spinous processes due to degenerative changes of the spine. Baastrup’s disease usually affects the lumbar spine, with L4-L5 being the most commonly affected level. There is higher occurrence at ages over 70 and no gender predilection. Symptoms include back pain with midline distribution that worsens during extension, is relieved during flexion and is exaggerated upon finger pressure at the level of interest. Diagnosis rests on clinical examination and imaging studies. The hallmark of imaging findings is the close approximation and contact of adjacent spinous processes, with all the subsequent findings including oedema, cystic lesions, sclerosis, flattening and enlargement of the articulating surfaces, bursitis and occasionally epidural cysts or midline epidural fibrotic masses. Proposed therapies include conservative treatment, percutaneous infiltrations or surgical therapies such as excision of the bursa or osteotomy. The purpose of this study is to illustrate the spectrum of imaging findings in Baastrup’s disease and to emphasise upon including the syndrome in the list of potential causes of low-back pain. Teaching Points • Baastrup’s disease refers to close approximation of adjacent spinous processes. • Diagnosis of Baastrup’s disease is verified with clinical examination and imaging studies. • Contact of adjacent spinous processes results in oedema, sclerosis, flattening and enlargement. • Proposed therapies include conservative treatment, percutaneous infiltrations or surgical therapies.

Moderate to severe acne requires treatment with a combination of topical and oral drugs such as antibiotics, hormones and retinoids. Retinoids have many contraindications and adverse effects requiring close monitoring. The study's objectives were to describe prescribing trends in acne medication over time in a military setting, and assess physician adherence to guidelines for acne treatment, including drug precautions, clinical monitoring, and treatment progression. METHODS We conducted a descriptive, serial cross-sectional study of acne drugs prescribed in the Israel Defense Forces (IDF) in the years 2002-2007, analyzing the classes of drugs prescribed and patient characteristics. In addition, the clinical quality of the medical encounter was assessed by examining physician adherence to IDF guidelines. RESULTS Between 2002 and 2007, 64,281 patients were treated for acne. Treatment courses generally persisted for 1-2 months. Over 70 % of female patients receiving oral retinoids were not concomitantly receiving oral contraceptives. CONCLUSION This study provides a unique perspective of acne treatment in a military setting, overall displaying good adherence to general guidelines. The common prescription of oral retinoids to young females without concomitant contraception is alarming.

Abstract
Isolated fallopian tube torsion (IFTT) is a rare occurrence characterized by the rotation of the fallopian tube on its own axis, without twisting the ipsilateral ovary. Pre-operative diagnosis is difficult due to the lack of specific clinical symptoms and radiological signs. The etiology is to date unknown and only some pre-disposing factors have been reported. The history, clinical presentation, laboratory findings and surgical treatment of five patients aged 12-16 with IFTT were evaluated. All patients came to be examined for worsening abdominal pain, nausea or vomiting. 75% of them practiced sports involving sudden changes in body position. They all underwent blood tests, ultrasound and Magnetic Resonance and then laparoscopy for the persistence of acute symptoms. Laparoscopic salpingectomy was performed in three patients. Another two needed a conversion to open salpingectomy due to the presence of pelvic adhesions. During the follow-up period, every girl was fine. The cause of IFTT is undetermined. In this series, a close association between IFTT and sports causing rapid body movements was found. The possibility of IFTT should be considered in the differential diagnosis of acute abdominal pain in children or adolescent females, especially if they practice sports.

Abstract
An 83-year-old woman who complained of dizziness and nausea visited our hospital. An electrocardiogram showed ST-segment elevation in multiple leads and an echocardiogram showed severe hypokinesis of the anteroseptal wall of the left ventricle. However, emergency coronary angiography showed no stenotic lesions in any coronary arteries. A laboratory examination showed thrombocytopenia, renal dysfunction, and hemolysis. We therefore diagnosed the patient with thrombotic thrombocytopenic purpura (TTP). While we were preparing to initiate plasma exchange therapy, she suddenly developed cardiopulmonary arrest. A postmortem examination revealed microthrombi in the small vessels of the myocardium. We herein report a case of ischemic cardiomyopathy with a rapid progression from TTP.

Abstract
Syringomyelia secondary to cervical spondylosis is a rare entity to encounter in clinical practice. We discuss the case of a 53-year-old lady who presented with a syringomyelic syndrome and was found to have cervical spondylosis on imaging. Cine-MRI revealed an obstruction of cerebrospinal fluid (CSF) flow in the cervical spinal subarachnoid space. Decompression of the same led to clinical and radiological improvement. There is a potential causal association between cervical spondylosis and syringomyelia. MRI CSF flow studies may help in deciding the course of treatment in such cases. A subset of patients with cervical spondylosis and concurrent spinal cord signal intensity changes may show reversal of the same following intervention.

Abstract
Chlamydia pneumoniae, a pathogenic bacteria responsible for respiratory tract infections, is known as the most implicated infectious agent in atherosclerotic cardiovascular diseases (CVDs). Accumulating evidence suggests that C. pneumoniae-induced oxidative stress may play a critical role in the pathogenesis of CVDs. Indeed, the overproduction of reactive oxygen species (ROS) within macrophages, endothelial cells, platelets and vascular smooth muscle cells (VSMCs) after C. pneumoniae exposure, has been shown to cause low density lipoprotein oxidation, foam cell formation, endothelial dysfunction, platelet adhesion and aggregation, and VSMC proliferation and migration, all responsible for the typical pathological changes of atherosclerotic plaque. The aim of this review is to improve our insight into C. pneumoniae-induced oxidative stress in order to suggest potential strategies for CVD prevention. Several antioxidants, acting on multi-enzymatic targets related to ROS production induced by C. pneumoniae, have been discussed. A future strategy for the prevention of C. pneumoniae-associated CVDs will be to target chlamydial HSP60, involved in oxidative stress.

Abstract
INTRODUCTION Maffucci syndrome is a rare, congenital, non-hereditary mesodermal dysplasia, manifested by multiple enchondromas and hemangiomas. Malignant transformation of these lesions is seen in up to 40% of the cases. CASE REPORT We present a case of a patient with Maffucci syndrome and an associated chondrosarcoma of the nose. Treatment consisted of surgical resection. Because of the low grade of the tumor, additional treatment, such as radiotherapy, was not necessary. CONCLUSION Maffucci syndrome is an exceedingly rare mesodermal dysplasia. Its manifestation in the head and neck region is even less common. Malignant transformation of the associated enchondromas is common, and should be considered whenever a change of the clinical course occurs. Random, periodically performed X-ray examinations give little additional information on malignant transformation and are considered useless.

Abstract
We present a unique presentation of Crohn's disease in a 25-year-old male with a 3-month history of progressive gastric outlet obstruction symptoms including reflux, vomiting, postprandial pain and weight loss, with no other symptoms. Multiple imaging investigations as well as gastroscopic biopsies revealed a non-specific prepyloric lesion, without evidence of malignancy. A distal gastrectomy was performed. Subsequent histological evaluation revealed gastroduodenal Crohn's disease. Follow-up revealed no evidence of disease elsewhere in the gastrointestinal system or systemically. While it is not uncommon for Crohn's disease to involve the stomach and duodenum, it is rare for gastroduodenal disease to be the initial presentation. Isolated gastroduodenal Crohn's disease typically presents with non-specific gastritis-like symptoms over a number of years. This patient had a unique course of Crohn's disease with rapid onset of symptoms, predominantly relating to gastric outlet obstruction and no prior or subsequent history of gastrointestinal symptoms.

Abstract
BACKGROUND Non-melanoma skin cancer (NMSC) is the most common malignancy in the United States. Recommended treatment for NMSC remains surgical excision following a positive biopsy. Evidence of complete spontaneous regression of residual NMSC exists in the case of small lesions macroscopically removed by shave biopsy, but with a positive microscopic margin. The present study investigates the rate at which residual tumor is present at subsequent excisional biopsy, with the aim to assess if recommendation to forgo surgical excision can be made. METHODS A total of 233 shave biopsies of basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) were performed during a 5-year period. All specimens included in the study were less than 2 cm in diameter, were macroscopically removed by shave biopsy, and had a positive initial microscopic margin. RESULTS On subsequent surgical excisional biopsy, 42% of BCC specimens were negative for residual tumor, 38% had residual tumor, but the tumor was completely contained in the excised specimen, and 20% of the specimens had positive margin residual tumor. For SCC specimens, 73% were negative for residual tumor, 21% had residual tumor, but the tumor was completely contained in the excised specimen, and 6% of the specimens had positive margin residual tumor. CONCLUSIONS Although reduction of residual tumor at reexcision is noted with both BCC and even more so with SCC, the rate at which this occurs is not sufficient that a general recommendation to forgo surgical excision can be made.

Abstract
Background Morquio A syndrome is an autosomal recessive lysosomal storage disease often resulting in life-threatening complications. Early recognition and proficient diagnosis is imperative to facilitate prompt treatment and prevention of clinical complications. Methods Experts in Asia Pacific reviewed medical records focusing on presenting signs and symptoms leading to a diagnosis of Morquio A syndrome. Results Eighteen patients (77% female) had a mean (median; min, max) age of 77.1 (42.0; 0.0, 540.0) months at symptom onset, 78.9 (42.0; 4.5, 540.0) months at presentation and 113.8 (60.0; 7.0, 540.0) months at diagnosis. Orthopedic surgeons and pediatricians were most frequently consulted pre-diagnosis while clinical geneticists/metabolic specialists most frequently made the diagnosis. Delayed diagnoses were due to atypical symptoms for 5 patients (28%), while 4 patients (22%) experienced each of subtle symptoms, symptoms commonly associated with other diseases, or false-negative urine glycosaminoglycan analysis. Two patients (11%) each experienced overgrowth within the first year of life. Two patients with Morquio A syndrome (11%) were diagnosed with craniosynostosis and 1 (6%) for each of Legg-Calvé-Perthes disease, Leri-Weill syndrome, and pseudoachondroplasia. Early radiographic features of Morquio A syndrome led to more efficient diagnosis. Conclusions Increased awareness of clinical symptomology overlapping with Morquio A syndrome is essential. Clinicians encountering patients with certain skeletal dysplasia should consider Morquio A syndrome in their differential diagnosis. Atypical or subtle symptoms should not eliminate Morquio A syndrome from the differential diagnosis, especially for patients who may have non-classical phenotype of Morquio A syndrome.

Abstract
Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin’s lymphoma (NHL) with increasing incidence in older males, females and blacks. However, it has not yet been reported, to present with acute liver failure in patients with preexisting chronic liver disease due to human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. We describe a case of ACLF as the presenting manifestation of DLBCL in an elderly black man with HIV/HCV co-infection and prior Hodgkin’s disease in remission for three years. The rapidly fatal outcome of this disease is highlighted as is the distinction of ACLF from decompensated cirrhosis. Due to the increased prevalence of HIV/HCV co-infection in the African American 1945 to 1965 birth cohort and the fact that both are risk factors for chronic liver disease and NHL we postulate that the incidence of NHL presenting as ACLF may increase.

Abstract
Le Carcinome papillaire intra-kystique du sein est une entité très rare et représente 0,5 à 1% de l'ensemble des carcinomes mammaires. Il se caractérise généralement par une croissance lente avec un bon pronostic. Nous rapportons 03 nouveaux cas prouvés histologiquement, chez des patientes traitées par chirurgie radicale ou conservatrice, suivie d'une radiothérapie sur le sein en place et une hormonothérapie à base de tamoxifen chez les deux patientes avec des récepteurs hormonaux positifs. Les trois patientes sont en bon contrôle locorégionale avec des suivis post-thérapeutiques de 12 à 18 mois.

Abstract
INTRODUCTION Flat-back syndrome is one of the main causes of surgical failure after lumbar fusion and can lead to a revision surgery to correct it. Three-column pedicle subtraction osteotomy is an efficient technique to restore lumbar lordosis (LL) for fixed sagittal malalignment. The fusion mass stemming from the past surgeries makes the procedure demanding as most anatomical landmarks are missing. MATERIAL AND METHODS This review article will focus on the correction of this lack of LL through the fusion mass. We will successively review the preoperative management, the surgical specificities, and various types of clinical cases that can be encountered in flat-back syndromes. CONCLUSION PSO in the fixed fusion mass is technically demanding. Preoperative CT-scan and preoperative navigation allow us to push the limits when anatomical landmarks disappear. Bleeding and neurologic are the two major complications feared by the surgeon. The best way to avoid these revision surgeries is to restore a proper lumbar lordosis at the time of initial surgery by considering lumbo-pelvic indexes.

Abstract
Ovarian cancer is still the deadliest of all gynecologic malignancies in women worldwide. This is attributed to two main features of these tumors, namely, (i) a diagnosis at an advanced tumor stage, and, (ii) the rapid onset of resistance to standard chemotherapy after an initial successful therapy with platin- and taxol-derivatives. Therefore, novel targets for an early diagnosis and better treatment options for these tumors are urgently needed. Epidemiological data show that induction and biology of ovarian cancer is related to life-time estrogen exposure. Also experimental data reveal that ovarian cancer cells share a number of estrogen regulated pathways with other hormone-dependent cancers, e.g., breast and endometrial cancer. However, ovarian cancer is a heterogeneous disease and the subtypes are quite different with respect to mutations, origins, behaviors, markers, and prognosis and respond differently to standard chemotherapy. Therefore, a characterization of ovarian cancer subtypes may lead to better treatment options for the various subtypes and in particular for the most frequently observed high-grade serous ovarian carcinoma. For this intention, further studies on estrogen-related pathways and estrogen formation in ovarian cancer cells are warranted. The review gives an overview on ovarian cancer subtypes and explains the role of estrogen in ovarian cancer. Furthermore, enzymes active to synthesize and metabolize estrogens are described and strategies to target these pathways are discussed.

Primary hyperparathyroidism during pregnancy. Arch Gynecol Obstet 2014; 291:259-63.

Abstract
PURPOSE Primary hyperparathyroidism (pHPT) during pregnancy is rare and associated with increased morbidity and mortality for both mother and fetus. This review aims to draw together recent thinking on pregnancy and pHPT. METHODS We have performed a Pubmed (Medline(®)) search with no time limit using "primary hyperparathyroidism", "pregnancy" or "management" as keywords. We reviewed 37 articles in English and French languages on pHPT characteristics, clinical presentations, pregnancy complications, birth outcomes and management of pHPT during pregnancy. RESULTS The diagnosis of pHPT is characterized by an elevated serum calcium level associated with an inappropriate increase in the parathyroid hormone level. The clinical manifestations are directly related to the calcium level. Usual techniques to detect parathyroid adenoma or hyperplasia, as computerized tomography and 99mTc-sestamibi scintigraphy, are not recommended in pregnancy. Thus, ultrasonography of the neck is the current first-line investigation during pregnancy for localization of parathyroid diseases. pHPT during pregnancy with mildly elevated calcium levels may be managed with medical treatment: intravenous or oral rehydratation, with or without forced diuresis. Few drugs are available for pHTP during pregnancy; calcitonin and cinacalcet require further study; bisphosphonate should be restricted to life-threatening hypercalcemia. Surgery is the only curative treatment and is recommended when calcium levels are above 2.75 mmol/L. It should be performed in the second trimester and considered in the third trimester if there is inadequate response to medical therapy. CONCLUSION Early diagnosis of pHPT in a pregnant woman, followed by appropriate management and treatment, has been shown to significantly reduce maternal and fetal complications.

HPV16-E7 expression in squamous epithelium creates a local immune suppressive environment via CCL2- and CCL5- mediated recruitment of mast cells. PLoS Pathog 2014; 10:e1004466.

Abstract
Human Papillomavirus (HPV) 16 E7 protein promotes the transformation of HPV infected epithelium to malignancy. Here, we use a murine model in which the E7 protein of HPV16 is expressed as a transgene in epithelium to show that mast cells are recruited to the basal layer of E7-expressing epithelium, and that this recruitment is dependent on the epithelial hyperproliferation induced by E7 by inactivating Rb dependent cell cycle regulation. E7 induced epithelial hyperplasia is associated with increased epidermal secretion of CCL2 and CCL5 chemokines, which attract mast cells to the skin. Mast cells in E7 transgenic skin, in contrast to those in non-transgenic skin, exhibit degranulation. Notably, we found that resident mast cells in E7 transgenic skin cause local immune suppression as evidenced by tolerance of E7 transgenic skin grafts when mast cells are present compared to the rejection of mast cell-deficient E7 grafts in otherwise competent hosts. Thus, our findings suggest that mast cells, recruited towards CCL2 and CCL5 expressed by epithelium induced to proliferate by E7, may contribute to an immunosuppressive environment that enables the persistence of HPV E7 protein induced pre-cancerous lesions.

Abstract
Left ventricular wall rupture (LVWR) comprises a complication of acute myocardial infarction (AMI). Acute LVWR is a fatal condition, unless the formation of a pseudoaneurysm occurs. Several risk factors have been described, predisposing to LVWR. High index of suspicion and imaging techniques, namely echocardiography and computed tomography, are the cornerstones of timely diagnosis of the condition. As LVWR usually leads to death, emergency surgery is the treatment of choice, resulting in significant reduction in mortality and providing favorable short-term outcomes and adequate prognosis during late follow-up. Herein, we present two patients who were diagnosed with LVWR following AMI, and subsequent pseudoaneurysm formation. In parallel, we review the aforementioned condition.

Abstract
The disease concept of clear cell (tubulo) papillary renal cell carcinoma (CCP-RCC) as a distinct subtype of renal cell carcinoma has been recently established. First described in the setting of end stage renal disease, this tumor type is more frequently recognized and encountered in a sporadic setting. In this article, we provide an overview of the recent understanding of this tumor. Macroscopically, tumors are well circumscribed with well-developed tumor capsule. Histologically, the tumor cells are cuboidal to low columnar cell with clear cytoplasm and papillary and tubulo-papillary configuration. Immunohistochemically, tumor cells generally show diffuse expression for cytokeratin 7, CA9 (cup-shaped pattern), HIF-1, GLUT-1 and high molecular weight cytokeratin, but negative for AMACR, RCC Ma and TFE3. CD10 is negative or focally positive in most tumors. Genetically, this tumor has no characteristics of clear cell RCC or papillary RCC. Prognostically, patients with CCP-RCC behave in an indolent fashion in all previously reported cases. In conclusion, although this tumor has been integrated into recent International Society of Urologic Pathology Classification of renal neoplasia, both aspects of disease concept and clinical behavior are yet to be fully elucidated. Further publications of large cohorts of patients will truly help understand the biologic potential and the molecular underpinnings of this tumor type.

Abstract
Background We investigated whether the anti-atherosclerosis of adiponectin (APN) relates to the reduction of oxidative stress. We observed the overexpression of adiponectin gene with different titers on atherosclerosis (AS) models of high-fat apolipoprotein E-deficient (ApoE−/−) mice. Material/Methods We divided 48 male ApoE−/− mice into 4 groups: control group, high-fat diet group, low adiponectin group, and high adiponectin group. The low and high adiponectin group mice were treated with recombinant adenovirus expressing mice adiponectin (Ad-APN) with low-dose adiponectin 1.0×108 p.f.u. and high-dose adiponectin 5.0×108 p.f.u. via the tail every 2 weeks and given a high-fat diet for the last 8 weeks. On the 14th day after injection, blood samples were obtained from the vena cava. Results Along with increased serum adiponectin, serum superoxide dismutase (SOD) activity increased (P<0.05) and concentration of malondialdehyde (MDA) was decreased (P<0.05). Levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) were decreased, especially TC and LDL-C (P<0.05). A real-time fluorescent quantitative polymerase chain reaction test was used to analyze levels of mRNA expression for endothelial nitric oxide synthase (eNOS) and adiponectin in the aorta. Along with increased adiponectin, the mRNA expression of eNOS in the aorta was increased significantly (P<0.05). The lesion formation in the aortic sinus was inhibited by 25% and 31% in the low-APN group and high-APN group, respectively (P<0.05). Along with the increase of adiponectin doses, the damage of atherosclerosis gradually eased. However, the differences between the low-APN group and high-APN group had no statistical significance. Conclusions Adiponectin may protect the aorta from atherosclerosis injury by reducing oxidative stress, reducing lesion formation size in the aortic root and reducing TC, TG, and LDL-C in serum. The molecular mechanism may involve preservation of SOD, reducing MDA in serum, and increasing eNOS and adiponectin mRNA expression in the aorta.

Abstract
Russell body esophago-gastro-duodenitis is an unusual form of chronic inflammation, with only 22 cases being reported in PubMed. However, the prevalence and clinical significance remain unknown. This report describes the clinico-pathological characteristics of nine cases of Russell body gastritis (RBG) and one case of Russell body duodentitis (RBD), with nonspecific endoscopic appearance. The Mott cells (plasma cells with Russell bodies) showed κ light chain restriction in eight gastritis cases and λ light chain restriction in the duodentitis case, and there were no histological features that suggested lymphoma. Thus, a diagnosis of monoclonal RBG/RBD was made. Helicobacter pylori infection was found in 55.6% of RBG cases and in the RBD case. And, the clinical follow-up evaluations were uneventful. This report is the first study to describe this benign disease entity with monoclonality on a large-scale basis. In addition, the monoclonality of Mott cells cannot be used as evidence of an existing neoplastic lesion, and taken together, these findings may indicate a reactive process.

Abstract
Schwannomas are rare tumors originating from the Schwann cells, which form the neural sheath. These tumors occur most frequently in the head, neck, arms and limbs. Primary schwannomas of the colon and rectum are extremely rare; they are usually benign, but in extremely rare cases (2%), they can present with malignant degeneration if not surgically removed. The current study presents the case of a 65-year-old male with blood in the feces who underwent a colonoscopy that revealed an oval-shaped mass covered by ulcerated mucosa. A standard biopsy examination indicated a gelatinous carcinoma, and the patient consequently underwent a laparoscopic resection of the left colon. Histological examination revealed a schwannoma. Immunohistochemistry showed the tumor to be positive for S100 and vimentin, but negative for cluster of differentiation (CD)117, cytokeratin (CK)7, CK20, chromogranin, actin and synaptophysin, with a Ki-67 proliferative index of 3%. Lymph nodes were not involved. Overall, pre-operative biopsy examinations may be difficult for schwannomas, and immunohistochemistry is necessary for the correct diagnosis of this condition. In contrast to gastrointestinal stromal tumors, schwannomas are negative for CD117 and positive for S100 protein and vimentin. A Ki-67 index of ≥5% is strictly correlated with greater tumor aggressiveness. Therefore, the gold standard treatment for schwannomas is oncological radical surgical resection.

Abstract
Inflammatory bowel disease (IBD) is increasing in incidence in both the developed and the developing world. Genetic, immunological and environmental factors are known to be involved. Genome-wide studies have examined the contribution played by host genetics in the development of IBD and have estimated that genetic factors are responsible for about 25 % of the disease risk. Having an IBD-associated genotype does not always lead to development of the disease phenotype, and hence it seems likely that environmental factors are key to triggering development of the disease in genetically susceptible individuals. The gut microbiota contains more cells than its human host, and mounting evidence attests to the importance of the microbiota in the development of several diseases, including IBD, metabolic syndrome and CVD. The present paper reviews the interplay between the microbiota and the mucosal immune system in health and in IBD; and discusses the evidence base for the use of therapeutic modulation of the microbiota to prevent and treat IBD.

Abstract
PURPOSE Chin-on-chest deformity is a rare and severe condition mostly related with ankylosing spondylitis, traumas and/or cervical spine surgery. We present a case of 69 years old woman with a rare form of chin-on-chest secondary to dropped head syndrome (DHS), developed after radiotherapy for Hodgkin disease. In addition, we reviewed the few publications about this specific condition; management and surgical treatment of DHS are discussed. METHODS We performed a pedicle subtraction osteotomy (PSO) and stabilization through a posterior approach. Intraoperative monitoring using motor and somatosensory evoked potentials and wake-up test were carried out. RESULTS At 19th month follow-up, the patient reported a significant improvement of cervical pain, dysphagia and respiratory difficulty and a complete restoration of the neurological impairment. The achieved correction was successful and the patient was very satisfied by the restoration of forward gaze. CONCLUSIONS DHS is a very rare post-radiotherapy complication; there is lack of evidences in literature about its management. The only definitive treatment seems to be surgical intervention. PSO is a valid therapeutic option when fixed chin-on-chest deformity occurs; although it is a demanding technique and it presents high rate of complications, the actual neurological monitoring methods provide more intraoperative safety.

Behavioral testing-related changes in the expression of Synapsin I and glucocorticoid receptors in standard and enriched aged Wistar rats. Exp Gerontol 2014; 58:292-302. [PMID: 25218493 DOI: 10.1016/j.exger.2014.09.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2014] [Revised: 07/28/2014] [Accepted: 09/08/2014] [Indexed: 11/22/2022]
Abstract
Our aim was to assess the changes in the Synapsin I and glucocorticoid receptor (GR) expression induced by behavioral testing in the dorsal and ventral hippocampi of standard and enriched aged Wistar rats. The environmental enrichment (EE) was carried out 3h/day over a period of two months and then, the rats were tested in the elevated zero-maze (EZM) and radial-arm water maze (RAWM). Behavioral results showed that, even at an advanced age, EE was able to reduce anxiety-related behaviors and improve the performance in the RAWM. Regarding the neurobiological data, Synapsin I expression in the dorsal CA3, but not in the ventral, was enhanced both in enriched and standard rats when they performed the behavioral testing. Interestingly, the EE exposure was enough to increase Synapsin I in the ventral CA3. The analysis of GR in the dorsal hippocampus showed an increase of this receptor in the dDG both in enriched and standard rats when they performed the behavioral testing, whereas in the dCA1 and dCA3, the effect of the testing depended on the previous housing condition. In the ventral region, we found that the effects of EE were higher because on the one hand, the GR expression induced by the behavioral testing was enhanced in the dSUB, vCA1 and vCA3 when the rats were previously enriched and on the other hand, EE, regardless of the behavioral testing, increased the GR expression in the vDG and vSUB. Therefore, our results suggest that the effect of the behavioral testing on the neurobiological mechanisms studied is different depending on the previous housing condition of aged rats.

Masimango MI, Sumaili EK, Jadoul M, Wallemacq P, Mubagwa DK, Makulo RJR, Lepira FB, Nseka NM. Prevalence of microalbuminuria and diagnostic value of dipstick proteinuria in outpatients from HIV clinics in Bukavu, the Democratic Republic of Congo. BMC Nephrol 2014; 15:146. [PMID: 25189092 PMCID: PMC4164710 DOI: 10.1186/1471-2369-15-146] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2014] [Accepted: 08/28/2014] [Indexed: 11/10/2022] Open
Abstract
Background Microalbuminuria is a marker of early kidney disease and high cardiovascular risk in various populations, including HIV positive patients. However, the diagnostic value of qualitative (dipstick) proteinuria and the burden of microalbuminuria in HIV positive patients living in sub-Saharan Africa are relatively unclear. Methods In a cross-sectional study, 235 HIV- positive outpatients were screened for proteinuria in 3 HIV-clinics in Bukavu. A spot urine sample from each subject was tested both by a dipstick and albumin-creatinine-ratio (ACR) assay. The performance of dipstick proteinuria exceeding 1+ was compared with that of microalbuminuria (≥30 mg/g creatinine). Results The prevalence of microalbuminuria and dipstick proteinuria ≥ (1+), ≥ (2+) and ≥ (3+) was 11%, 41%, 3.5% and 0.7%, respectively. Compared to microalbuminuria, the dipstick (proteinuria of 1+ or greater) had an overall sensitivity of 60% and a specificity of 61%. The positive predictive value was 15.4% and the negative predictive value 92.8%. Conclusion Proteinuria is highly prevalent in HIV positive patients. The limited sensitivity and specificity of the dipstick to detect significant microalbuminuria make it unattractive as a screening tool in HIV positive patients.

Abstract
Ischemic stroke may occur in patients in whom vascular imaging shows the ipsilateral internal carotid artery (ICA) to be occluded. In younger patients this is often due to carotid artery dissection, while in older people this most likely results from cardiac embolism or thrombosis secondary to high-grade stenosis at the carotid bifurcation. Interventional techniques aim at recanalization of the carotid artery for early restoration of cerebral blood flow and secondary prevention of future strokes. In chronic ICA occlusion the ischemic infarct may be related to hemodynamic compromise. In this situation, extracranial-intracranial bypass surgery was introduced, but its role remains still unclear. Ischemic stroke may also occur in patients with a chronic occlusion of the contralateral ICA. This situation demands the usual stroke treatment, but surgical and neuroradiological interventions face a higher risk than unilateral vascular pathology. Medical treatment supports stroke prevention in carotid artery occlusion.

Abstract
PURPOSE OF REVIEW Pouchitis, representing a spectrum of disease phenotypes, is the most common long-term complication in patients who have undergone restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Its management and prevention are challenging. RECENT FINDINGS Treatment modalities vary according to phenotypes of pouchitis. The medical therapy of pouchitis remains largely empiric and antibiotic-based. However, patients may develop de-novo chronic antibiotic-refractory pouchitis (CARP) or progress from acute antibiotic-responsive phenotype. Patients with CARP often require alternative medical approaches to routine antibiotics, including the use of oral or topical mesalazine, corticosteroids, and sometimes immunomodulators or biological agents against tumour necrosis factor. There are two strategies to prevent pouchitis, the primary (i.e., the prevention of the initial episode) and secondary (i.e., the prevention of recurrent episodes) prophylaxis. There are scant data in the literature on nutritional aspects. SUMMARY We evaluated the efficacy of current strategies of prevention and treatments of pouchitis and propose algorithms, including attention to nutrition wherein data exist.

Abstract
Background Recent studies suggested that aquaporins 5 (AQP5) was associated with many kinds of cancers and regulated many processes of various kinds of cancer cells. Our previous studies also demonstrated that AQP5 was highly expressed in epithelial ovarian cancer and contributed to the progress of ovarian cancer. Methods Lentivirus for knocking-down the expression of AQP5 was prepared and verified by qPCR and Western blotting. Cell counting kit-8 (CCK8) assay and transwell assay were performed to investigate the role of AQP5 on proliferation and migration of 3AO cells. The effects of down-regulating AQP5 on tumorigenesis were tested by tumor xenografts experiments. Results An effective lentivirus silencing AQP5 expression was obtained and used in this study. Down-regulating AQP5 inhibited proliferation and migration of cultured human epithelial ovarian cancer 3AO Cell. Furthermore, interfering of AQP5 during tumorigenesis could efficiently decrease the tumor growth in athymic mice. Conclusions These findings altogether suggest that AQP5 regulated multi processes in ovarian carcinogenesis and may be an attractive therapeutic target.
