[Limitations of the Xpert-MTB/RIF® assay in the initial diagnosis of tuberculosis in the context of a rural hospital in Ethiopia]. / Limitaciones del ensayo Xpert-MTB/RIF® en el diagnóstico inicial de tuberculosis en el contexto de un hospital rural en Etiopia.

OBJECTIVE: To evaluate the implementation of Xpert-MTB/RIF®, as an early diagnosis technique, in a rural area of Ethiopia. METHODS: Data were retrospectively collected from those patients over 13 years of age who were requested to take the Xpert MTB/RIF® test in a rural hospital located 45 km from the reference laboratory, during the first 3 years of its implementation (2015, April -2018, April). RESULTS: A total of 306 patients older than 13 years were evaluated, in 85 (27.8%) there was an error in the processing of the test and the result was not obtained. Of the 221 samples with results, the median time between obtaining the sample and receiving the result was 21 days and 42 of them were positive (19%, 95% CI: 14.2-24.9%). The sample with the highest diagnostic yield was adenopathy (88.8%; [8/9]; p<0.001). CONCLUSIONS: There are more bacteriological diagnoses with Xpert-MTB/RIF®, but with a delay in obtaining the result and its main objective, which is early diagnosis, is not achieved.

[Intrabiliary rupture of hepatic echinococcosis cysts: presentation of a clinical case and review of the literature]. / Rottura intrabiliare di cisti da echinococcosi epatica: presentazione di un caso clinico e revisione della letteratura.

Intrabiliary rupture of hydatid cyst of liver is a complication of hydatid disease. The authors report the case of a patient surgically treated by total pericistectomy and suture communication with biliary system, the best treatment for this condition.

[Unusual localizations of hydatid cyst. Epidemiological aspects and diagnostic problems. Description of a clinical case]. / Localizzazioni inusuali delle cisti di echinococco. Aspetti epidemiologici e problematiche diagnostiche. Presentazione di un caso clinico.

A rare case of primary hydatid cyst of the mesentery is described. Though cystic echinococcosis infestation can occur in any part of the body primary peritoneal involvement is rare. The mechanism of primitive peritoneal infection by the parasite is still unclear. The hypotheses which can explain this rare primary localization, the sensitivity and the specificity of the serological and instrumental tests and the therapeutic management of this atypical lesion are discussed.

[Non-Hodgkin's lymphoma of the testis. Report of a clinical case and review of the literature]. / Il linfoma non Hodgkin del testicolo. Presentazione di un caso clinico e revisione della letteratura.

The Authors report a case of primary non-Hodgkin's lymphoma of the testis. Although lymphoma is a rare neoplasm, it is commonest tumor in the elderly age. Surgical therapy is essential but some times it can be associated to radio-chemotherapy.

[Rectorrhagia caused by lipoma of the hepatic flexure of the colon. A case report and review of the literature]. / Rettorragia da lipoma della flessura epatica del colon. Descrizione di un caso clinico e revisione della letteratura.

The Authors report a case of intestinal bleeding due to lipoma of the epatic flexure. Lipomas are the commonest mesenchymal benign tumors that can be found in the colon and are second as frequence only to the adenomatous polyps. They are most frequent in the right colon and shown an opposite distribution in comparison with adenocarcinomas and adenomatous polyps. When tumor size is greater than 3 cm, lipomas become symptomatic. Radiological and endoscopic investigations provide orientative elements for diagnosis. In lipomas less than 2 cm in diameter an endoscopic treatment is feasible.

[Considerations and results of the use of paramomycin in the prevention of infectious complications in colorectal surgery]. / Considerazioni e risultati sull'uso della paramomicina nella prevenzione delle complicanze infettive in chirurgia colorettale.

The efficacy of short term prophylaxis in the prevention of infection has been tested in 72 patients who underwent surgical treatment for colorectal pathology. General tolerance to the antibiotics was good. The Authors took this remark as a starting point for reviewing the literature and making comments.

[Retroperitoneal leiomyosarcoma: clinical case]. / Il leiomiosarcoma del retroperitoneo: caso clinico.

The Authors have reported a case of retroperitoneal leiomyosarcoma. The retroperitoneal localization is quite unusual and early diagnosis is difficult. Only surgery operation and radio-chemotherapy can improve the prognosis. Tumor size is the major prognostic factor.

[Apudoma of Vater's ampulla: case report and review of the literature]. / Apudoma dell'ampolla di Vater: caso clinico e revisione della letteratura.

The Authors report a case of Vater's ampulla apudoma and after having examined the characteristics of these neoplasms they discuss clinical presentation, diagnostic and treatment problems of islet cell adenomas. They review the literature and make some remarks.

[Is blood transfusion a risk factor in colorectal surgery for cancer?]. / L'emotrasfusione è un fattore di rischio nella chirurgia colorettale per cancro?

Personal experience in the treatment of 93 cases of cancer of the large bowel and rectal localization is reported 32 patients (A group) received blood transfusions, 61 patients (B group) hadn't any transfusions or autotransfusions. Postoperative morbidity was 34.37% in A group and 14.75% in B group. The Authors stress the basic importance of autotransfusions as well in patients surgically treated for colorectal cancer.

[Lipoma of the small intestine: a rare cause of intestinal invagination]. / Il lipoma del tenue: una rara causa d'invaginazione intestinale.

Lipomas are an uncommon cause of small-bowel obstruction. The symptoms are intermittent and nonspecific. The Authors report a case in which intussusception was diagnosed with echography and the obstruction was treated with resection. They conclude that lipomas must always be considered in the differential diagnosis of intrabdominal neoplasms and in intestinal obstructions.
