A case of pulmonary actinomycosis presented with endobronchial involvement.

Pulmonary actinomycosis is a rare infectious disease, which is characterized by a wide range of symptoms and no specific imaging findings and may be confused with neoplasia, tuberculosis or pneumonia. Endobronchial involvement of actinomycosis may be caused by aspiration of foreign bodies or broncholithiasis and may bronchoscopically masquerade as malignancy. A case of 68-year-old man is reported, who presented with productive cough and fever and had no response to antibiotic therapy with moxifloxacin. Patchy air-space consolidation on left lower lobe was demonstrated on CT and flexible bronchoscopy revealed an endobronchial white necrotized mass, causing partial occlusion of bronchus and masquerading as lung cancer. Endobronchial actinomycosis was confirmed by biopsies of lesion, which revealed radiating filamentous colonies of Actinomyces and no evidence of malignancy. The patient was successfully treated with intravenous penicillin G for two weeks, followed by doxycycline per oral for six months, achieving full resolution of lesion on follow-up CT and bronchoscopy and no recurrence of symptoms.

Double Pylorus: Report of a Case With Endoscopic Follow-Up and Review of the Literature.

Double pylorus is a rare endoscopic finding that has been reported in 0.001% to 0.4% of upper gastrointestinal endoscopies and can be either congenital or acquired. Acquired double pylorus is usually an uncommon complication of peptic ulcer that erodes and creates a fistula between the duodenal bulb and the prepyloric antrum. We describe a case of a 67-year-old man who experienced mild epigastric pain and dyspepsia over the last 6 months. The patient periodically took nonsteroidal anti-inflammatory drugs (NSAIDs) due to joint pain. Esophagogastroduodenoscopy revealed gastritis and a double pylorus. An accessory channel connected the lesser curvature of the prepyloric antrum to the duodenal bulb and the endoscope was able to be passed through both of the ducts. The Helicobacter pylori quick test proved positive. Two years later, a follow-up endoscopy showed that fistula fused with normal pylorus and there was a single large opening.

Coagulation and inflammation biomarkers may help predict the severity of community-acquired pneumonia.

BACKGROUND AND OBJECTIVE: There are limited data on the relationship between the severity of community-acquired pneumonia (CAP) and biomarkers of inflammation and coagulation. The aim of this study was to evaluate the association between the severity of CAP and serum levels of antithrombin III (AT-III), protein C (P-C), D-dimers (D-D) and CRP, at hospital admission. METHODS: This was a prospective observational study in 77 adults (62.3% men), who were hospitalized for CAP. The severity of CAP was assessed using the confusion, uraemia, respiratory rate >or=30 breaths/min, low blood pressure, age >or=65 years (CURB-65) score. RESULTS: Forty patients (52%) had severe CAP (CURB-65 score 3-5). Serum levels of AT-III were lower and levels of D-D and CRP were higher in patients with severe CAP than in patients with mild CAP (CURB-65 score 0-2) (P < 0.001 for all comparisons). Levels of P-C were lower in patients with severe CAP compared with those with mild CAP, but the difference was not significant (P = 0.459). At a cut-off point of 85%, AT-III showed a sensitivity of 80% and a specificity of 75%, as a determinant of the need for hospitalization. At a cut-off point of 600 ng/mL, D-D showed a sensitivity of 90% and a specificity of 75% and at a cut-off point of 110 mg/L, CRP showed a sensitivity of 83% and a specificity of 79%, as determinants of the need for hospitalization. CONCLUSIONS: Serum levels of AT-III, D-D and CRP at admission appear to be useful biomarkers for assessing the severity of CAP.

Trend in incidence of cardiovascular risk factors in elderly and over-aged stroke patients between 2003 and 2007 in Greece.

The aim of this study is to identify the main cardiovascular risk factors (CRFs) in patients over 65 years with ischemic stroke. This is a retrospective study in 175 patients that were hospitalized in our department due to ischemic stroke in the period 2006-2007. The patients were divided in two groups: Group I--elderly (65-80 years) and Group II--over-aged (>or=81 years). The results were compared with a similar study performed in our department in the period 2002-2003 in 160 ischemic stroke patients. Statistical analysis was made by the chi2-test. Hypertension, either alone or in combination with other CRFs, constitutes the main CRF. Diabetes mellitus (DM) is not frequently the sole CRF but its coexistence with other CRFs ranks DM as the second most important CRF, with the largest percentage in the elderly. Dyslipipidemia is 4th CRF in order following the coronary heart disease (CHD). Taking into account that the provision of acute therapeutic intervention in elderly and over-aged ischemic stroke patients is in most cases difficult, because of their age and the high risk of thrombolysis in these patients, there is increased need to focus on primary prevention of ischemic stroke by treating associated CRF.

Hypokalemia induced myopathy as first manifestation of primary hyperaldosteronism - an elderly patient with unilateral adrenal hyperplasia: a case report.

INTRODUCTION: Primary hyperaldosteronism is only rarely caused by unilateral adrenal hyperplasia. CASE PRESENTATION: A 73-year-old hypertensive Greek man (on 10 mg amlodipine for the last ten years) presented in the emergency department with severe muscle weakness of all limbs. The initial physical and laboratory examination revealed normal blood pressure, muscle weakness, severe hypokalemia, sinus rhythm and U wave, rhabdomyolysis and metabolic alkalosis. The patient was immediately treated with intravenous administration of potassium-rich solutions, 25 mg spironolactone with progressive dose titration up to 100 mg. Because of high arterial blood pressure, irbesartan was added. On day 6, muscle weakness was completely restored with decrease of arterial blood pressure and further improvement of laboratory tests. The combination of hypokalemia with arterial hypertension raised the suspicion of primary hyperaldosteronism; therefore, we performed abdomen computed tomography scan, which revealed a nodular mass (15 mm in diameter) in the left adrenal gland. Plasma renin activity was in the lower normal range with a three-fold increase of plasma aldosterone concentration. We performed total resection of the left adrenal gland and the histopathological examination revealed hyperplasia of the left adrenal gland. CONCLUSION: This report presents a rare case of an elderly patient under antihypertensive treatment the last ten years for essential hypertension, who admitted to our emergency department with hypokalemia - induced myopathy as first manifestation of primary hyperaldosteronism due to unilateral adrenal hyperplasia.

Solitary large hepatic metastasis in an elderly patient with anaplastic thyroid carcinoma: a case report.

BACKGROUND: We present the case of a patient who presented with anaplastic thyroid carcinoma with a solitary large liver metastasis. Hepatic metastases are extremely rare in anaplastic thyroid carcinoma. CASE PRESENTATION: We report the case of a 78-year old Greek man who presented with voice hoarseness, dyspnoea and a large mass on the anterior surface of the cervical region (neck), as well as constitutional symptoms such as anorexia, weight loss and malaise. On physical examination, the thyroid was hard and tender on palpation and a liver mass was palpable. Routine biochemistry yielded normal results except increased C-reactive protein, alkaline phosphatase and gamma-glutaryl transferase. Other biochemical tests including tumor markers, thyroid hormones, antithyroid antibodies, hepatitis B and hepatitis C antibodies were negative. Imaging methods revealed enlargement of the left thyroid lobe extending to the anterior mediastinum and compressing the trachea, metastatic bilateral pulmonary lesions and a large, nodular, contrast-enhanced mass-occupying lesion in the right hepatic lobe. The findings of fine-needle aspiration biopsy of the thyroid were consistent with anaplastic carcinoma. Liver biopsy showed infiltrations by poorly differentiated anaplastic cells, few of which were slightly positive for thyroglobulin. These findings were suggestive of a hepatic metastasis originating from anaplastic thyroid carcinoma. During his hospitalization, the patient suffered progressive obstruction of the trachea due to rapid increase of the thyroid gland mass. The tumor was considered unresectable due to its advanced stage, as well as the presence of extrathyroid metastatic lesions. The patient was irradiated on cervical region (neck) and upper mediastinum with a daily dose of 300 cGy for 10 days which resulted in mild improvement of obstructive phenomena. However, his clinical condition deteriorated rapidly and he died within a few days. CONCLUSION: Solitary, large hepatic metastasis may constitute a rare complication in anaplastic thyroid carcinoma.

Haemarthrosis after superwarfarin poisoning.

INTRODUCTION: Superwarfarins are widely used as rodenticides. They are similar to warfarin, but they are more potent and act longer. In case of poisoning, they cause severe bleeding, usually from multiple sites. CASE REPORT: A 67-yr-old man was admitted with melaena, epistaxis and haemarthrosis in his left knee. PT, INR and aPTT were markedly increased. Initially, the patient was treated with blood and fresh frozen plasma (FFP) transfusions. However at the second day, PT, INR and aPTT were even worse. The combination of persistent coagulopathy, normal mixing studies, normal liver function tests and absence of hepatic failure or malabsorption syndromes lead to the suspicion of vitK dependent clotting factors deficiency due to superwarfarin poisoning. Indeed, the patient admitted a suicide attempt with rodenticide, although he had previously denied it. Psychiatric evaluation revealed a disturbed personality. Melaena stopped after 7 d. Then, the patient was administered 30 mg of vitK daily for a total period of 4 months. CONCLUSIONS: Superwarfarin poisoning leads to severe bleeding, usually from multiple sites. Prolonged treatment with high doses of vitK is necessary. Haemarthrosis, as a complication of superwarfarin poisoning, is presented here for the first time in literature.

Incidence and etiology of acute non-malignant upper gastrointestinal bleeding in northern Greece.

AIM: To evaluate the incidence and etiology of acute non-malignant upper gastrointestinal bleeding (ANMUGIB) in northern Greece due to increased use of non-steroidal anti-inflammatory drugs (NSAIDs), including low-dose aspirin (L-A), exposure and geographical variability of Helicobacter pylori (Hp) seroprevalence. METHODS: A retrospective study of 110 patients admitted for hematemesis or melena during a 6-month period. All patients had undergone a gastrointestinal (GI) endoscopy during hospitalization. The presence of Hp was identified by biopsies and a (13)C-urea breath test in the case of Hp(-) biopsy bleeding peptic ulcer (BPU). The activity of ANMUGIB was assessed according to Forrest's classification. Statistical analysis was made by the chi(2)-test and Yates' correction. RESULTS: Most patients were in the two medium age groups with no significant difference between them (P < 0.001). NSAID or L-A (100 mg/day) use was reported in 42.73% of patients in a ratio 1:1 (P > 0.1) and Hp infection was found in 29.09% of patients. BPU, with approximately two-thirds in the bulb, erosions and varices were the most frequent sources. Hp infection was found in 60.65% of BPU, 65.57% were related to NSAIDs or L-A and 8.19% were non-Hp non-NSAID/L-A BPU. Flat spots were most commonly found with a significant difference (P < 0.001) to other stigmata of recent bleeding, except for clean base. CONCLUSIONS: In northern Greece, persons aged over 40 years are prone to ANMUGIB with a non-significant relationship to males. Hp infection and medication use, such as NSAIDS and L-A, are deeply involved in its etiology. Non-Hp non-NSAID/L-A BPU are a small proportion. ANMUGIB seems to have a generally good prognosis.
