A rare form of abruptio placenta and clinical presentation in a preterm labor case: Breus' mole.

A normotensive pregnant woman who had no historical risk factors for abruption placenta and found to have Breus' mole that indicates the pattern of single or multiple hematoma protrude above the chorionic plate was encountered. The case resembled a large fetal abdominal wall defect coexisting with a singleton live-born fetus at 27 weeks of gestational age is presented. The obstetric ultrasound showed that multiple coiled masses in the amniotic cavity, both the fetus and the placenta were normal. After two courses of tocolysis therapy, a healthy and, 1,400 g live-born infant was delivered through cesarean section due to fetal distress. Apgar scores at 1 and 5 min were 5 and 8, respectively. The infant died on postnatal day 6 due to severe respiratory distress and prematurity. This rare condition probably occurs frequently in missed abortion and the etiology is unknown, but is probably related to circulatory disturbance on maternal site. We report a rare clinical presentation and review the literature of Breus' mole.

The protective effect of nitroglycerin on gastrointestinal and renal side effects of lornoxicam in rats.

UNLABELLED: The aim of this study is firstly, to determine the preventive effect of chronic usage of combination of nitroglycerin and lornoxicam on gastrointestinal and renal side effects and secondly, to investigate the oxidative and antioxidative effects of this combination in rats. METHODS: Thirty-seven Wistar male rats were divided into five groups for 15 days; isotonic group (n = 8, sodium chloride 0.09, Group ISO), lornoxicam group (n = 8, lornoxicam 1.3 mg/kg, Group L), nitroglycerin group (n = 6, nitroglycerin 1 mg/kg, Group NTG), lornoxicam-nitroglycerin combination group (n = 8, 1.3 mg/kg lornoxicam + 1 mg/kg nitroglycerin, Group L-NTG), and control group (n = 7, no drug was administered, Group C). Nitric oxide, malondialdehyde, reduced glutathione (GSH), catalase, interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha concentrations were measured before drug injection and on fifteenth day in all blood samples. Gastrointestinal and renal biopsies were performed on fifteenth day. RESULTS: Two rats died on tenth and twelfth days in Group L. There were significant differences in Group L compared to the other groups for the lesions of stomach and kidney (p = 0.01, p = 0.028 respectively). Gastric ulceration was occurred in a rat in Group L. Malondialdehyde, TNF-alpha, and IL-6 levels decreased in NTG and L-NTG groups, whereas catalase and glutathion levels increased in NTG, L and L-NTG groups compared to control group (p < 0.05). CONCLUSION: Lornoxicam may cause gastrointestinal and renal side effects without oxidative stress. Adding nitroglycerin to lornoxicam for chronic treatment may prevent these side effects and enhance antioxidative effect compared to the use of lornoxicam alone in rats.

[Bronchiolitis obliterans organizing pneumonia presenting with solitary pulmonary nodule and spontan pneumothorax].

Chronic obstructive pulmonary disease (COPD) is characterized with progressive airflow limitation as a result of abnormal inflammation due to inhalation of various noxious gases and particulate dusts. COPD is an increasing important health problem that is parallel to the increasing habit of tobacco smoke. Tracheobronchial infections seem to be the most important cause of exacerbation in COPD, however pneumothorax and pulmonary thromboembolism are also important determinant factors in the attack's severity. Since the tobacco smoking is the common risk factor in both COPD and lung cancer, solitary pulmonary nodules especially in smokers should be carefully examined. Bronchiolitis obliterans organizing pneumonia (BOOP) is an uncommon pulmonary disorder, the clinical spectrum of which is variable. In this case report, a COPD patient manifesting spontaneous pneumothorax and solitary pulmonary nodule has been discussed who was diagnosed as BOOP after surgical procedure.

Pulmonary lymphomatoid granulomatosis evolving to large cell lymphoma in the skin.

Lymphomatoid granulomatosis is an angiodestructive, angioinvasive lymphoproliferative disorder. It involves most frequently lungs, central nervous system and skin. Recent studies indicate that lymphomatoid granulomatosis is an Epstein-Barr virus associated B cell disorder with a background of reactive T lymphocytes. In a 49 year old woman presenting with fever, malaise and pulmonary masses the diagnosis of lymphomatoid granulomatosis was established histologically by open lung biopsy. Following the initial diagnosis the patient was found to have gastric and skin involvement. The skin lesion was diagnosed as diffuse large B-cell lymphoma.

Primary neuroendocrine carcinoma of the mediastinum.

A mediastinal mass was found in a 37 year old male who presented with fever, weight loss and fatigue. The chest CT revealed a 9x6x4 cm well circumscribed mass located paratrachaelly in the upper mid-mediastinum. The mass was removed by right thoracotomy. Macroscopically the tumor weighed 195 g and measured 9x6x4 cm. Microscopically the tumor consisted of small blue cells in solid and trabecular pattern. Immunohistochemical studies performed for differential diagnosis of small blue cell tumors. The tumor was diagnosed as primary neuroendocrine carcinoma of the mediastinum. This case is presented for its rare recurrence in that particular location.

Cavitary necrobiotic nodule imitating malignant lung disease in a patient without articular manifestations of rheumatoid arthritis.

Pulmonary involvement is a serious complication of rheumatoid arthritis (RA) and may be seen as airway disease, rheumatoid nodules, interstitial lung disease, and pleurisy. However, cavitary rheumatoid nodules without articular manifestations are rare. We describe a male patient presenting with pleurisy and multiple rheumatoid necrobiotic nodules in the absence of arthritis or subcutaneous nodules. One of the nodules was quite large (5 x 8 cm in diameter) and cavitary, imitating bronchial carcinoma radiologically and bronchoscopically. Definite histopathologic diagnosis was obtained by open lung biopsy. The patient was given methylprednisolone and methotrexate, and significant regression was observed in clinical and radiologic findings. He has been followed for 14 months with no articular manifestations yet, receiving 4 mg/d methylprednisolone and 20 mg/wk methotrexate. The diagnosis of rheumatoid pulmonary involvement without articular manifestations can be difficult. Rheumatoid nodules may imitate bronchial carcinoma, or bronchial carcinoma may coexist in RA patients. Open lung biopsy may be necessary for differential diagnosis of pulmonary lesions in RA.

Transthoracic echocardiographic documentation of disappearance of massive pulmonary artery thromboemboli after fibrinolytic therapy.

In this paper, we report two cases of acute massive pulmonary thromboemboli with pulmonary artery thrombus, in which disappearance of thrombus followed fibrinolytic therapy were documented at transthoracic echocardiographic follow-up. Data from these limited experiences suggest that, transthoracic echocardiography might be useful as a first diagnostic screening in cases of suspect pulmonary thromboembolism and thrombolytic therapy might be considered in patients with pulmonary artery thrombus with pulmonary embolism.
