The OLGA-OLGIM staging and the interobserver agreement for gastritis and preneoplastic lesion screening: a cross-sectional study.

Stomach cancer (SC) incidence and mortality are relevant public health issues worldwide. In Colombia, screening for preneoplastic lesions (PNL) and the presence of H. pylori is not routinely performed. Therefore, the aim of this study was to evaluate OLGA-OLGIM staging and the interobserver agreement in gastritis and preneoplastic lesions in patients with gastroduodenal symptoms from Colombia. A cross-sectional study was conducted in 272 patients with gastroduodenal symptoms. Gastric biopsies were taken following the Updated Sydney System with the OLGA-OLGIM classification, and the results were evaluated by two pathologists. Chronic gastritis and PNL were reported in 76% and 24% of the patients, respectively. Furthermore, 25% of the patients with PNL displayed gastric atrophy (GA) and 75% intestinal metaplasia (IM). Agreement in the histopathological reading for IM was good, whereas for OLGA was variable, and for the H. pylori quantity was poor. OLGA-OLGIM stages 0-II were the most frequent (96%), while stage III (4%) and SC (4%) were the least frequent. Age and coffee consumption were associated with a higher prevalence of PNL. This work determined that 4% of the population is at high risk of developing SC and would benefit from follow-up studies. Reinforcement of training programs to improve the agreement in histopathology readings is required.

Nodular Pulmonary Amyloidosis: A Manifestation of Sjögren's Syndrome.

CASE DESCRIPTION: A 72-year-old woman with primary Sjögren Syndrome (SS) was diagnosed during an inpatient hospital stay with dry symptoms. The patient had respiratory and constitutional symptoms, requiring a pulmonary imaging evaluation by high-resolution computed tomography (HRCT) of the thorax. CLINICAL FINDINGS: Multiple cavitary pulmonary nodules, halo sign, and focal areas of ground-glass opacity with predominance in both bases were found in the images. Complementary studies were done where a neoplastic focus was ruled out. The diagnosis of nodular pulmonary amyloidosis was confirmed with a pulmonary biopsy performed by videothoracoscopy for histopathological study, which reported the formation of nodules in the parenchyma with amyloid deposits and positive immunohistochemical markers for CD3, CD20, and CD38 lymphocytic infiltration. TREATMENT AND OUTCOME: Initial inpatient management with intravenous cyclophosphamide and methylprednisolone was given. Subsequent outpatient management was given with high dose glucocorticoids. CLINICAL RELEVANCE: We presented a case of nodular pulmonary amyloidosis in a female patient with primary SS, which is a rare pulmonary manifestation of this syndrome.

Panhipopituitarismo secundario a metástasis del sistema nervioso central por un adenocarcinoma broncogénico / Panhypopituitarism secondary to metastasis of the central nervous system due to a bronchogenic adenocarcinoma

Resumen Mujer de 45 años de edad con antecedente de extabaquismo pesado, cursó con cuadro crónico de cefalea en región occipital irradiado a región temporal asociado a disminución de la agudeza visual de ojo izquierdo. El cuadro empeoró en los últimos seis meses y se asoció a polidipsia y poliuria. Presentó cuadro sincopal con amnesia retrógrada, para lo cual se realizó una tomografía axial computarizada (TAC) contrastada de cráneo que mostró múltiples lesiones parenquimatosas cerebrales y del cerebelo compatibles con metástasis. Se hizo estudio hormonal para evaluar la función hipofisiaria evidenciando un panhipopituitarismo secundario. Se detectó foco primario neoplásico mediante TAC contrastada de tórax, evidenciando una lesión espiculada en el lóbulo superior derecho sugestiva de carcinoma broncogénico, posteriormente se tomó biopsia por fibrobroncoscopia el cual confirmó por histopatología e inmunohistoquímica el diagnóstico de un adenocarcinoma broncogénico.

Abstract A 45-year-old woman with a history of heavy extabaquism presented with chronic headache in the occipital region irradiated to the temporal region associated with decreased visual acuity of the left eye. The picture worsened in the last six months and was associated with polydipsia and polyuria. She presented a syncopal picture with retrograde amnesia, for which a contrast computed tomography (CT) of the skull was performed, which showed multiple parenchymal brain and cerebellar lesions compatible with metastasis. Hormonal study was done to evaluate the hypophyseal function evidencing a secondary panhypopituitarism. A primary neoplastic focus was detected by a contrast chest CT scan, showing a spiculated lesion in the right upper lobe suggestive of bronchogenic carcinoma. A biopsy was subsequently taken by fibrobronchoscopy, which confirmed the diagnosis of a bronchogenic adenocarcinoma by histopathology and immunohistochemistry. (Acta Med Colomb 2018; 43: 115-118).
