Type I Neurofibromatosis (NF1) is an autosomal-dominant inheritable disorder, with an incidence of 1:3,000, and a prevalence of 1:4,000 to 5,000. Pathogenesis is based on mutations of the NF1 gene, a tumor suppressor gene encoding a cytoplasmic protein named neurofibromin that controls cellular proliferation. Patients affected by NF1 typically present with cutaneous neurofibromas, cafè au lait spots and eye involvement, but they can also be affected by various visceral tumors, such as neurofibromas (nodular or plexiform type), gastrointestinal stromal tumors or endocrine tumors, such as pheochromocytomas. Visceral neurofibromas are often asymptomatic but when growing in size they may present with pain, palpable abdominal mass, symptoms secondary to bowel obstruction or main vessels compression, and even gastrointestinal bleeding when mucosa or submucosa are involved. In these cases surgery becomes mandatory in order to remove all neoplastic tissue. The Authors describe a case of a young man affected by NF1 with associated retrocaval abdominal mass with compression and displacement of the inferior vena cava, thus requiring a complex surgical procedure.

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Aim. The most efficacious surgical treatment for renal hyperparathyroidism is still subject of research. Considering its low incidence rate of long-term relapse, “presumed” total parathyroidectomy without autotrasplantation (TP) may be indicated for secondary hyperparathyroidism (2HPT) in patients with chronic kidney disease (CKD), not eligible for kidney transplantation. The aim of this study was to analyse the TP long-term results in 2HPT haemodialysis (HD) patients. Method. Between January 2004 and October 2009, 25 2HPT HD patients, not eligible for kidney transplantation, underwent TP of at least four parathyroid glands. Clinical status and intact parathyroid hormone (iPTH) serum levels were assessed intraoperatively and during a 36-month follow-up. Results. TP improved the typical clinical symptoms and a significant reduction of iPTH serum levels was achieved in each patient. Aparathyroidism was never observed; in case of severe postoperative hypocalcemia, hypocalcemic seizures were never reported and the long-term recurrence rate was 8%. Only one patient received a kidney transplantation. Postoperative cardiovascular events (hypertension, peripheral artery disease, arrhythmia, coronary or cerebrovascular disease) were observed in 32% of cases and mortality rate was 16%. Conclusions. Considering its low long-term relapse rate and the absence of postoperative aparathyroidism, TP may still be considered the treatment of choice in patients with aggressive forms of 2HPT or of advanced dialytic vintage, with no access to renal transplantation. In case of postoperative hypoparathyroidism, hypocalcaemia can be effectively managed by medical treatment.

Increased incidence of incidental cancer in patients operated for benign thyroid disease has been reported. We report our experience about incidental thyroid cancer (ITC) in order to better characterize this nosologic entity. Between 2001 and 2009 a total of 568 patients underwent surgery for benign thyroid disease. Patients with preoperative cytology undetermined or positive for malignancy were excluded. The most frequent indication for surgery was multinodular or diffuse nontoxic goiter. We performed total thyroidectomy in 499 cases and emithyroidectomy in 69 cases. Final histology revealed ITC in 53 patients (9.3%): 44 had papillary carcinoma (20 classic variant and 24 follicular variant), 4 follicular carcinoma, 4 medullary carcinoma and 1 primitive thyroid paraganglioma. The preoperative diagnosis was multinodular or diffuse goiter in 45 cases of ITC and uninodular goiter in 8 cases. We performed total thyroidectomy in 46 case, emithyroidectomy in 4 patients with past history of lobectomy, emithyroidectomy in 3 patients with following radicalization and central neck dissection. In 14 patients the tumor was multifocal and in 12 of these patients the tumor foci were bilateral. The lesion was a microcarcinoma in 34 cases. Mean diameter of the ITC was 1.14 cm. We retrospectively reconsidered the results of preoperative ultrasound examinations in relation to the exact position of the tumor in the specimens and we found a statistically significant association between echogenicity and papillary histotype. Twenty-six patients were followed up at our Hospital. The mean follow-up period was 38.2 months. A relapse was observed in 3/26 patients. Incidental thyroid cancer in patients operated for benign disease has its own surgical and oncological relevance. A correct preoperative assessment, with a careful selection of nodules for fine-needle aspiration cytology on the basis of ultrasound pattern, could better address the choice of surgical procedure. The non irrelevant incidence of incidental thyroid cancer, the eventuality of multifocality and bilaterality and the possible occurrence of relapse, support that total thyroidectomy without residuum is a valuable option for treating benign thyroid conditions such as multinodular goitre. When an incidental cancer is diagnosed after emithyroidectomy, a radicalization with central neck dissection could be considered. We suggest that natural history of papillary microtumors and the correct surgical approach for these lesions could be better defined with a more extensive use of “Porto proposal” criteria.

The Whipple’ Disease (W.D.) is a very rare disease with an incidence of 1 per 1.000.000 inhabitants; it is a systemic infection that may mimic a wide spectrum of clinical disorders, which may have a fatal outcome and affects mainly male 40-50 years old. The infective agent is an actinomycete, Tropheryma Whipplei (T.W.) that was isolated 100 years after first description by Wipple, and identified in macrophages of mucosa of the small intestine by biopsy which is characterized by periodic acid-Schiff-positive, products of the inner membrane of his polysaccharide bacterial cell wall. The multisystemic clinical manifestations evolve rapidly towards an organic decay characterized by weight loss, malabsorption, diarrhea, polyathralgia, opthalmoplegia, neuro-psychiatric disorders and sometimes associated to endocarditis. Early antibiotic treatment with trimethoprim and sulfometathaxazole reduces the fatal evolution of the disease. The authors present a rare experience about a female subject in which the clinical gastrointestinal signs were preceded by neuro-psychiatric disorders, and evolved into obstruction and intestinal perforation which required an emergency surgery with temporary ileostomy, recanalized only after adequate medical treatment with a full dose of antibiotic and resolution of clinical disease for the high risks of fistulae for the edema and lymphadenopathy of mucosa. The diagnosis was histologically examined by intestinal biopsy performed during surgery, which showed PAS-positive histiocytes, while PRC polymerase RNA was negative, which confirms the high sensibility of PAS positive and low specificity of RNA polymerase for T.W.

PURPOSE: To evaluate quality of life in Portuguese patients with Systemic Lupus Erithematosus (SLE) and its correlation with disease activity and cumulative damage. METHODS: We included consecutive SLE patients, fulfilling the 1997 ACR Classification Criteria for SLE and followed at the Rheumatology Department of the University Hospital of Coimbra, Portugal at time of visit to the outpatient clinic. Quality of life was evaluated using the patient self-assessment questionnaire Medical Outcomes Survey Short Form-36 (SF-36) (validated Portuguese version). The consulting rheumatologist fulfilled the SLE associated indexes for cumulative damage (Systemic Lupus International Collaborating Clinics- Damage Index: SLICC/ACR-DI) and disease activity (Systemic Lupus Erythematosus Disease Activity Index: SLEDAI 2000). Correlation between SLEDAI and SLICC and SF-36 was tested with the Spearman Coefficient. Significant level considered was 0.05. RESULTS: The study included 133 SLE patients (90.2% female, mean age - 40.7 years, mean disease duration - 8.7 years). Most patients presented low disease activity (mean SLEDAI = 4.23) and limited cumulative damage (mean SLICC = 0.76). Despite that, SF-36 mean scores were below 70% in all eight domains of the index. Physical function domains showed lower scores than mental function domains. The QoL in this group of patients is significantly impaired when compared with the reference Portuguese population (p<0.05 in all domains). There was no correlation between clinical activity or cumulative damage and quality of life. CONCLUSION: QoL is significantly compromised in this group of SLE patients, but not related with disease activity or damage. These findings suggest that disease activity, cumulative damage and QoL are independent outcome measures and should all be used to assess the full impact of disease in SLE patients.

Background: It is believed that the glycemic index (GI) may be used as a strategy to prevent and control noncommunicable diseases (NCD). Obesity is a multifactorial condition, a risk factor for development of other NCDs. Among the different types, abdominal obesity is highlighted, which is essential for the diagnosis of metabolic syndrome, and it is related to insulin resistance, dyslipi-demia, hypertension and changes in levels of inflammatory markers. Such indicators are closely related to the development of Type 2 Diabetes and cardiovascular disease. Objectives: Discuss the role of GI as a strategy for the prevention and/or treatment of visceral obesity, subclinical inflammation and chronic diseases. Results and discussion: The intake of low GI diets is associated with glycemic decreases, and lower and more consistent postprandial insulin release, avoiding the occurrence of hypoglycemia. Moreover, consumption of a low GI diet has been indicated as beneficial for reducing body weight, total body fat and visceral fat, levels of proinflammatory markers and the occurrence of dyslipidemia and hypertension. The intake of low GI foods should be encouraged in order to prevent and control non-communicable diseases.

A patient with Graves’ disease was admitted with a thyroid storm. She had severe hypercalcaemia caused by thyrotoxicosis. Treatment was complicated by vomiting and diarrhoea. With intravenous ondansetron, hydration and bisphosphonates, GI symptoms improved and oral thyreostatics could be started. This, combined with bisphosphonate administration, resulted in a mild hungry bone syndrome.

Crohn’s disease is a granulomatous inflammatory bowel disease. Its pathologic findings include non-contiguous chronic inflammation and non-caseating granulomas, sometimes with extra-intestinal localizations. Sinonasal manifestations of Crohn’s disease are quite rare and only a few cases have been reported up to date in the worldwide literature. They are characterized by chronic mucosal inflammation, obstruction, bleeding and occasionally septal perforation. We report a case of sinonasal granulomatosis revealing Crohn’s disease in a 22-year-old woman and go over the available literature on sinonasal involvement in Crohn’s disease.

Creutzfeldt–Jakob disease (CJD) is a rare and fatal neurodegenerative disorder with a broad spectrum of early clinical manifestations, comprising neurological and psychiatric symptoms. The authors report the case of a patient admitted with a diagnosis of depressive disorder with psychotic symptoms, with post-mortem confirmation of CJD and discuss how CJD’s clinical heterogeneity can lead to misdiagnosis of the disease. Despite CJD’s unique pathogenesis, its kaleidoscopic presentation justifies the integrated investigation of patients with psychiatric symptoms, avoiding restrictive diagnosis.

Objectives: We report an atypical presentation of eosinophilic fasciitis and provide a concise overview of the literature. Materials and Methods: Clinical and laboratory findings in a patient presenting with fever and skin induration were recorded. A deep muscle biopsy was performed in order to confirm the diagnosis. Results: A spontaneous favourable clinical and radiological evolution was observed. Conclusion: The diagnosis of eosinophilic fasciitis is challenging due to the lack of pathognomonic signs and symptoms. As spontaneous resolution has been described, watchful waiting is defendable depending on the clinical presentation. Although magnetic resonance imaging (MRI) can be useful in establishing the diagnosis, a deep muscle biopsy remains the gold standard diagnostic tool.

Objectives: To report a case of Brucella peritonitis. Patient and methods: We describe the case of a patient and present a brief review of the few published reports. Results: The patient had alcoholic cirrhosis of the liver and was diagnosed with Brucella non-neutrocytic bacterascites. Conclusion: Brucellosis is a common zoonosis with worldwide distribution. It is a systemic disease with the potential to predominantly affect one organ or a specific system (focal brucellosis). However, peritoneal focalization of this disease is a very rare presentation.

Objectives: We present an atypical case of chronic mesenteric ischemia with weight loss as only clinical manifestation and endoscopic findings imitating Crohn´s disease. Materials and Methods: A CT Angiography of abdomen confirmed the diagnosis of mesenteric ischemia after total occlusion of celiac trunk and superior mesenteric artery. Results: The patient died due to severe sepsis, as a result of extended bowel infarction. Conclusions: The diagnosis of chronic mesenteric ischemia requires a high degree of clinical suspicion and can be life-saving if early conducted.

We present the case of a 33-year-old lady who was diagnosed with disseminated Kaposi’s sarcoma and HIV infection. The patient improved on highly active antiretroviral therapy (HAART), however, nine days into treatment, she became febrile and dyspnoeic and developed tender cervical and axillary lymphadenopathy. Despite treatment for suspected sepsis and immune reconstitution, she died in intensive care. Lymph node biopsies revealed coexistent Castleman’s disease and Kaposi’s sarcoma. Initiation of HAART can be rarely associated with unmasking and rapid progression of Castleman’s disease, a phenomenon called immune reconstitution. Urgent investigation and treatment with agents such as steroids and cytotoxic drugs can be life-saving.
