Primary uterine cervical cancer: correlation of preoperative magnetic resonance imaging and clinical staging (FIGO) with histopathology findings.

The most commonly used staging system for cervical cancer is based on the International Federation of Gynaecology and Obstetrics (FIGO) staging system. Magnetic resonance imaging (MRI) has been accepted as the optimal tool for evaluation of the main prognostic factors and selection of therapeutic strategy. The purpose of this study was to compare the preoperative clinical examination FIGO staging findings with MRI and postoperative pathology report in females with primary cancer of the cervix. The study prospectively included 46 females consecutively hospitalized at the Department of Gynaecology and Obstetrics at the "Sestre milosrdnice" University Hospital Center in Zagreb. Interviews, clinical examination, transvaginal ultrasound and MRI were performed in all patients. In selected patients the surgical procedure was done and the correlation of clinical findings according to FIGO classifications, MRI and histopathological findings was completed. According to FIGO classification, positive clinical findings for stage IIA were found in 26/46 (55.5%) and stage IIB in 20/46 (44.5%)patients. FIGO MR modified classification confirmed stage IIA in 30/46 (66.6%) and stage IIB in 16/46 (33.4%) patients. Surgery (Wertheim radical hysterectomy with bilateral pelvic and selective para-aortic lymphadenectomy) was performed in 33/46 (71%) patients with clinically, MR, cytologically and pathohistologically confirmed findings of cervical cancer: 26 patients with IIA clinically FIGO stage and 7 with IIB stage. MRI examination proved better than clinical examination in staging of cervical carcinoma with 90.9% versus 79.0% accuracy rate. We suggest the application of the following MR protocol in all clinically staged FIGO IIA and IIB patients: T1W, T2WI and postcontrast dynamic T1WI after 3 and 60 seconds and after 5 minutes, performed on 1.5T MR machine.

Comparison of single incision laparoscopic totally extraperitoneal and laparoscopic totally extraperitoneal inguinal hernia repair: initial experience.

BACKGROUND AND PURPOSE: Laparoendoscopic single-site (LESS) surgery has been implemented recently in many laparoscopic (LAP) surgical procedures. We report our initial experience with LESS totally extraperitoneal (LESS-TEP) inguinal hernia repair in relation to conventional LAP-TEP. PATIENTS AND METHODS: Between November 2008 and May 2009, 25 LESS-TEP repairs of inguinal hernia and 29 LAP-TEP repairs of inguinal hernia were performed in 44 patients. Data regarding patient demographics, type of hernia, operative time, complications, postoperative hospital stay, and recurrence were prospectively collected and analyzed. RESULTS: All 44 patients were men, aged 17 to 84 years. Of 44 men, 3 had bilateral inguinal hernias in the LESS-TEP group and 7 in the LAP-TEP group. The operative time for bilateral LESS-TEP was 60 ± 15.3 min (range 40-70 min) and 40 ± 21.6 min (range 20-100 min) for unilateral LESS-TEP, while for bilateral hernia LAP-TEP it was 60 ± 24.8 min (range 40-100 min) and for unilateral LAP-TEP it was 50 ± 14.2 min (range 40-80 min). Comparison of operative times in the LESS-TEP and LAP-TEP groups between the first and second half cohort resulted in significant reduction of operative time in the second half of the LESS-TEP group (P<0.001). There were no intraoperative complications. Discharge was within 72 hours for most patients in both groups. There was one early recurrence (mesh displacement) during a median follow-up period of 11.5 ± 2.5 months in the LESS-TEP group and no recurrences during the 11 ± 1.6 months in the LAP-TEP group. CONCLUSION: In our experience, LESS-TEP is a safe and feasible procedure with a short learning curve. In all analyzed parameters, it is comparable to conventional LAP-TEP. Further studies that compare LESS-TEP and conventional multiport LAP-TEP repairs with long-term follow-up evaluation are needed to confirm the initial experience.

Primary acantholytic squamous cell carcinoma of the cecum: a case report.

BACKGROUND: Acantholytic squamous cell carcinoma (ASCC) is an uncommon histopathologic variant of SCC, characterized by marked acantholysis, wherein the tumor cells demonstrate defective cohesion to one another in the cancer nest leading to a pseudoglandular or pseudovascular appearance. The most common site of ASCC is the sun-exposed areas of the skin. Sporadic cases of ASCC have also been reported in various mucosal membranes and organs but to our knowledge this is the first case of primary ASCC of the large bowel. CASE PRESENTATION: A 59-year-old woman underwent right hemicolectomy due to large tumor in cecum and initial part of the ascending colon. Microscopically, the tumor consisted of nests of focally keratinizing large, atypical, squamous epithelial cells. Approximately 70% of the tumor showed acantholytic changes and acantholysis was equally distributed through the entire tumor. Immunohistochemically tumor cells were diffusely positive for cytokeratin (CK) AE1/AE3 and focally positive for epithelial membrane antigen and syndecan 1. All other tested antibodies (CK7, CK 20, CK MNF116, E-cadherin, beta-catenin, p63, p16, CD31, CD34, CEA, estrogen, progesterone) showed negative reaction. Periodic acid Schiff and alcian blue staining showed no intracellular or extracellular mucinous material in the tumor. The diagnosis of acantholytic squamous cell carcinoma of the cecum was suspected and additional examination was recommended to exclude possibility of metastatic carcinoma. Extensive clinical examination which also included whole-body PET/CT scan showed no additional tumors. After the exclusion of possible metastatic disease the diagnosis of primary acantholytic squamous cell carcinoma of the cecum was confirmed. Six months after surgery the metastasis in small intestine and recurrence in the abdominal cavity at the site of surgery appeared and had the same morphological characteristic as the primary tumor in the cecum. CONCLUSION: We report a unique case of ASCC arising in cecum and on this way expands the range of tumors originating in colon. Reports of more cases of colonic ASCC would possibly help to elucidate origin, clinical behavior and therapy of these tumors.

Nontraumatic bilateral subdural hematoma caused by antiaggregation therapy: case report and review of the literature.

A 64-year-old female receiving clopidogrel and aspirin antiaggregation therapy after percutaneous coronary intervention for non-STEMI myocardial infarction developed nontraumatic bilateral subdural hematoma with dizziness, vertigo and headache. Craniotomy had to be postponed because of reduced ADP platelet aggregability. Four days after clopidogrel withdrawal and transfusion of 12 platelet concentrate units, ADP aggregation transiently normalized and bilateral trepanation with hematoma evacuation was performed. The procedure was followed by excellent neurologic and clinical recovery; however, decreased platelet aggregability was recorded by postoperative day 12 despite strict clopidogrel and other platelet inhibitor withdrawal. Suspicion of Glanzmann thrombastenia was excluded by flow cytometry. Two weeks after neurosurgery, the right femoral vein thrombosis was detected by color doppler ultrasonography and therapy with fractionated heparin was initiated, followed by warfarin. The risk and incidence of hemorrhagic complications of antiaggregation and anticoagulation therapy are discussed. Caution is warranted on prescribing this potentially harmful therapy to older patients, generally burdened with other chronic comorbidities.

Effects of low-level laser treatment on mouth dryness.

UNLABELLED: Mouth dryness (MD) is usually followed by inadequate mechanical cleaning of the mouth and decrease in the levels of salivary antimicrobial proteins (including secretory immunoglobulin A (sIgA)). It is accompanied by difficulties during speaking and food swallowing, with an unpleasant taste, burning sensations in the mouth and higher susceptibility to oral diseases. Low-level laser treatment (LLLT) can intensify cell metabolism and its application on salivary glands could improve salivation. The purpose of this study was to evaluate the effects of LLLT on salivation of patients suffering from MD. The study included 17 patients with MD. Their major salivary glands were treated with low intensity laser BTL2000 on 10 occasions. The whole unstimulated and stimulated saliva quantities were measured just before the 1st, after the 10th and thirty days following the last (10th) treatment. In the samples of unstimulated saliva concentrations of sIgA were estimated by using ELISA method and its quantity in the time unit was calculated. The visual analogue scale (VAS) score was used to assess burning and/or pain intensity at these three time points. Statistical tests revealed significant salivation improvement quantitatively and qualitatively, i.e. increase in the quantity of saliva and sIgA. VAS score was also significantly improved and no side effects were observed. CONCLUSIONS: According to the results of this study, application of LLLT to xerostomic patients' major salivary glands stimulates them to produce more saliva with better antimicrobial characteristics and improves the difficulties that are associated with MD. This simple non-invasive method could be used in everyday clinical practice for the treatment of MD.

Recurrent venous thrombosis despite 'optimal anticoagulation therapy' for antiphospholipid syndrome--could new oral anticoagulants solve the problem?

The aim was to determine the validity of the international normalized ratio (INR) and prothrombin time (PT) as a monitor for warfarin therapy in patients with lupus anticoagulants and recurrent thrombosis, and to investigate alternative approaches to monitoring warfarin therapy and new treatment options in these patients. A case is described of a 63-year-old female with antiphospholipid syndrome and recurrent venous thrombosis despite optimal adjusted warfarin therapy. In patients with lupus anticoagulants, the INRs obtained while receiving warfarin vary and often overestimate the extent of anticoagulation, while PT without receiving warfarin is often prolonged. In conclusion, lupus anticoagulants can influence PT and lead to INR that does not accurately reflect the true level of anticoagulation. Optimizing of (warfarin) oral anticoagulation therapy could be achieved by individual monitoring of anticoagulation effect with a test thatis insensitive to lupus anticoagulants (chromogenic factor X assay). Emerging oral anticoagulants, direct thrombin inhibitors and direct factor Xa inhibitors, such as dabigatran and rivaroxaban, with a predictable anticoagulant response and little potential for food or drug interactions, have been designed to be administered in fixed doses without coagulation monitoring and could be the treatment choice for these patients.

After 40 years gossypiboma caused spleen abscess.

We report a case of spleen abscess cased by foreign body (gossypiboma) after 40 years. After physical examination, laboratory, ultrasonography and CT findings with diagnosis of acute abdomen, 73 years old woman had undergone laparatomy. Operation revealed intraabdominal spleen abscess. Capsulotomy and drainage of the collection was performed before splenectomy. Histological examination showed foreign body material surrounded by chronic inflammation, foreign body-type multinucleated giant cells, extravasated red blood cells and fibroblastic proliferation. From anamnesis we found that woman was operated only once during a life with diagnosis of extrauterine pregnancy, 40 years ago. Spleen abscess caused by gossypiboma after 40 years was never described before. However, diagnosis like this is very well known but rarely published because medical-legal implication. Education, professionalism and cooperation of all persons involved in surgical procedure are very important to prevent accidentally mistakes.

Primary ovarian leiomyoma associated with endometriotic cyst presenting with symptoms of acute appendicitis: a case report.

BACKGROUND: Ovarian leiomyoma is a rare benign tumor that accounts for 0.5 to 1% of all benign ovarian tumors. It probably arises from smooth muscle cells in the ovarian hilar blood vessels but there are other possible origins including cells in the ovarian ligament, smooth muscle cells or multipotential cells in the ovarian stroma, undifferentiated germ cells, or cortical smooth muscle metaplasia. Additionally, smooth muscle metaplasia of endometriotic stroma, smooth muscle present in mature cystic teratomas, and smooth muscle in the walls of mucinous cystic tumor may explain their occurrence in the ovary in some cases. CASE PRESENTATION: A 31-year-old woman was admitted to our surgical emergency service with a one-day history of appendicitis-like symptoms. Upon laparotomy, there was a solid, oval left-sided ovarian tumor located behind the uterus. The tumor was sent to the pathology department. A diagnosis of primary ovarian leiomyoma associated with an endometriotic cyst was established. CONCLUSION: The origin of ovarian leiomyoma is still unresolved. In our case, the tumor probably arose from smooth muscle cells derived from myofibroblasts that originate from metaplastic ovarian stromal cells present in the rim of the endometriotic cyst. Despite its rarity, ovarian leiomyoma should be considered in the differential diagnosis of ovarian spindle cell tumors. Appropriate diagnosis may require additional immunohistochemical analysis in some cases.

Symptoms of annular pancreas exacerbated by pregnancy.

Annular pancreas is a rare embryonal abnormality. Its manifestation in adulthood is often pinpointed with a substantial delay, which is most often attributed to pancreatitis, biliary pathology or dyspepsia. We present a case of a 28-year-old woman who had exacerbating symptoms of high bowel obstruction from 20th week of pregnancy, progressing after premature delivery. Diagnostic work-up revealed partial annular pancreas compressing the duodenum. Despite attempts of conservative treatment, her state deteriorated to such an extent that surgery was indicated and gastrojejunal bypass created. Her postoperative recovery was uneventful. In cases in which symptoms of high bowel obstruction in pregnancy persist and prostration occurs, we suggest close monitoring and a more thorough diagnostic approach. The question remains whether annular pancreas presents a cause of pathologic findings, a cofactor, or a mere accidental diagnosis in the development of superposed pathologies.

A giant hemorrhagic adrenal pseudocyst: case report.

OBJECTIVE: To report a rare case of a giant hemorrhagic adrenal pseudocyst and highlight the importance of this entity to clinicians. CASE PRESENTATION: A 57-year-old woman presented with a 1-year history of abdominal pain and distension. Ultrasonography and multislice computed tomography revealed a giant cystic (partially solid) mass over the left suprarenal region measuring 20 x 17 x 15 cm. A complete endocrine workup failed to detect any hormonal hypersecretion. INTERVENTION: The patient was treated with tumor excision through transabdominal pararectal approach. Histopathological examination revealed a hemorrhagic adrenal pseudocyst. CONCLUSION: To our knowledge the case presented here appears to be one of the largest hemorrhagic adrenal pseudocysts reported so far. Radiological and clinical features of the tumor are nonspecific and histopathological examination is essential to establish definitive diagnosis. An open, laparotomic adrenalectomy is the preferred surgical technique for better control of such a large mass with active bleeding inside.

Biological value of melanoma inhibitory activity serum concentration in patients with primary skin melanoma.

Melanoma inhibitory activity (MIA) protein was identified in significant quantities in primary and metastatic malignant melanomas, where it has an important role in promoting tumor development and progression. Our hypothesis was that MIA serum level will be elevated in patients with metastases or local spreading of the disease before any symptom of such progression is clinically apparent. We compared MIA serum levels in two groups of patients with primary melanoma; those with positive as opposed to those with negative sentinel lymph nodes. In addition, MIA serum levels were studied in two control groups; patients with dysplastic nevi and patients with basal cell carcinoma. A blood sample was obtained from each patient included in the study and MIA levels were assessed using standard enzyme-linked immunosorbent assay method. Patients with histologically positive sentinel lymph nodes, meaning that tumor cells were found in the lymph nodes, had much higher mean MIA values than any other patient group considered in this study. With mean value of 14.53 ng/ml, it was almost twice as high as mean MIA value in patients with histologically negative sentinel lymph nodes (7.32 ng/ml) and more than twice as high than any of the two control groups (P<0.001). However, neither the classification by Clarke nor the classification by Breslow could be used to distinguish patients with positive sentinel lymph nodes from those with negative sentinel lymph nodes. In our opinion, MIA serum level is the ideal test for screening the tumor spread to sentinel lymph nodes.

Multifragment fracture of the patellar apex: basket plate osteosynthesis compared with partial patellectomy.

INTRODUCTION: The purpose of the present study was to evaluate and compare the long-term results of operative treatment of a multifragment fracture of the inferior patellar pole by basket plate osteosynthesis and partial patellectomy. MATERIALS AND METHODS: We retrospectively studied two groups of patients who had operative treatment of a multifragment fracture of the inferior patellar pole between 1988 and 2004. Seventy-one patients who had osteosynthesis by basket plate (Group 1) and 49 patients who had partial patellectomy (Group 2) were followed for an average of 5.3 years. The final evaluation was based on the modified Cincinnati Knee rating system test. RESULTS: The results were excellent or good in 90.1% patients of Group 1, and 73.5% patients of Group 2. Significant differences between the groups were noted with regard to knee pain, swallowing, level activity, compression pain, range of motion, muscular atrophy, muscular strength, and final patellofemoral score which confirms statistical analysis. CONCLUSION: The stability of the osteosynthesis by basket plate allows osseous consolidation of the fracture and permits immediate mobilization and early weight bearing. Osteosynthesis by basket plate can provide better clinical results.

Combined megaloblastic and immunohemolytic anemia associated--a case report.

A 55-year-old female with a history of psychosis and rheumatoid arthritis was admitted to the hospital for fatigue and dizziness. At admission, macrocytic anemia, high serum lactic acid dehydrogenase (LDH) and gastrin concentrations, decreased serum vitamin B12 concentration, with macroovalocytes and poikilocytes in peripheral blood smear suggested the diagnosis of pernicious anemia. Indirect antiglobulin test (IAT) was negative. Surprisingly, treatment by vitamin B12 and folic acid administered for two weeks was ineffective and followed by transitory worsening of hemoglobin concentration on day 8. Repeat direct antiglobulin test (DAT) and IAT were positive. This immunotransfusion conversion, suggesting the presence of autoimmune hemolytic anemia, could be explained by change in the macroblastic erythrocyte population, i.e. emerging red cells with completely exposed membrane antigens due to vitamin B12 treatment and/or higher degree of dysregulation of the lymphocyte clone secreting erythrocyte autoantibodies. We proposed the coexistence of pernicious and autoimmune hemolytic anemia; therefore, methylprednisolone was added to vitamin B12 treatment. This therapy successfully improved hemoglobin and erythrocyte concentration. Although megaloblastic-pernicious anemia is a common disease, association of pernicious and autoimmune hemolytic anemia with two mechanisms of hemolysis (ineffective erythropoiesis and immune mechanism) is a rare condition, with only several dozens of cases described so far.

Pancreatic endocrine tumor of uncertain behavior: a case report.

Pancreatic endocrine tumors are rare, and among them large non-functioning tumors of uncertain behavior are extremely infrequent. Non-functioning pancreatic endocrine tumors originate from the endocrine part of the pancreas but are not associated with a distinct hormonal syndrome. A rare case is presented of a 49-year-old woman with a well-differentiated endocrine tumor of uncertain behavior that presented with intermittent pain in the epigastrium radiating to the right subcostal region. Computed tomography showed a well-defined and circumscribed solid mass in the pancreas head. The pancreatic mass was surgically removed and submitted for histopathologic analysis. Microscopically, the tumor had relatively uniform cells with oval nuclei that coated trabecular and pseudoglandular structures, which also showed 1 mitosis per 10 VVP and proliferation activity measured with Ki67 of less than 2%. A focus of intravascular invasion was seen on one slide. Immunohistochemical analyses for NSE, chromogranin and synapthophysin were positive, which along with its size (over 2 cm in diameter) and reported angioinvasion indicated the diagnosis of pancreatic endocrine tumor of uncertain behavior. Although mostly considered as malignant, large non-functioning pancreatic endocrine tumors can sometimes express benign or uncertain behavior; therefore, a large number of factors should always be considered when determining the biological nature of these tumors.

Laparoscopic totally extraperitoneal hernia repair versus open Lichtenstein hernia repair: results and complications.

Whereas open Lichtenstein inguinal herniorrhaphy is generally accepted as a safe, well-understood method with a high success rate, the laparoscopic repair of a inguinal hernia is a fairly recent technique. Although the laparoscopic approach to a hernia repair procedure is associated with less pain and faster recovery than open repair, many surgeons are not familiar with this technique owing to technical demands and a long learning curve. This study compares the results and complications between open tension-free mesh (Lichtenstein) repair and laparoscopic total extraperitoneal (TEP) repair. The study cohort was comprised of 345 consecutive patients who underwent an inguinal herniorraphy procedure. An open hernia repair was performed on one group of patients (n = 233), whereas TEP repair was performed on the other (n = 112), and then the comparison of intra- and postoperative complications and results obtained from both techniques was done. The mean hospital stay was similar in both groups. The average operative time in the TEP group was 58.6 +/- 18.1 minutes, and the average operative time in the open group was 58.2 +/- 17.8 minutes. There was no difference in postoperative complication rates between the two groups, except for urinary retention, which patients who underwent TEP repair were more likely to get. The following major complications were recorded: 2 cases of urinary bladder perforation-1 during TEP repair and the other during Lichtenstein repair, but both with good postoperative outcome-and 1 case of pneumothorax, which occurred during the TEP procedure. Despite the fact that TEP is a demanding procedure, it may be performed efficiently with an acceptable operating time and a low complication rate.

Multiple metastases to the small bowel from large cell bronchial carcinomas.

AIM: Metastases from lung cancer to gastrointestinal tract are not rare at postmortem studies but the development of clinically significant symptoms from the gastrointestinal metastases is very unusual. METHODS: Formalin-fixed, paraffin-embedded tissues were cut into 5 microm thick sections and routinely stained with hematoxylin and eosin. Some slides were also stained with Alcian-PAS. Antibodies used were primary antibodies to pancytokeratin, cytokeratin 7, cytokeratin 20, epithelial membrane antigen, vimentin, smooth muscle actin and CD-117. RESULTS: We observed three patients who presented with multiple metastases from large cell bronchial carcinoma to small intestine. Two of them had abdominal symptoms (sudden onset of abdominal pain, constipation and vomiting) and in one case the tumor was incidentally found during autopsy. Microscopically, all tumors showed a same histological pattern and consisted almost exclusively of strands and sheets of poorly cohesive, polymorphic giant cells with scanty, delicate stromas. Few smaller polygonal anaplastic cells dispersed between polymorphic giant cells, were also observed. Immunohistochemistry showed positive staining of the tumor cells with cytokeratin and vimentin. Microscopically and immunohistochemically all metastases had a similar pattern to primary anaplastic carcinoma of the small intestine. CONCLUSION: In patients with small intestine tumors showing anaplastic features, especially with multiple tumors, metastases from large cell bronchial carcinoma should be first excluded, because it seems that they are more common than expected.
