Synchronous primary malignant neoplasms of colon and bladder.

Extracolonic and synchronous malignancies are rare in colorectal carcinomas. We report a 68-year-old man with complaints of rectal bleeding and hematuria. Endoscopic biopsies revealed synchronous adenocarcinoma of the colon and transitional cell carcinoma of the bladder.

The relation between plasma endothelin-1 levels and metabolic control, risk factors, treatment modalities, and diabetic microangiopathy in patients with Type 2 diabetes mellitus.

We evaluated the possible relation between plasma endothelin-1 (ET-1) levels and metabolic control, risk factors, treatment modalities, and diabetic microangiopathy, including nephropathy, neuropathy, and retinopathy in patients with Type 2 diabetes and healthy control group. Sixty-eight (39 females and 29 males) patients with Type 2 diabetes and 14 (6 females and 8 males) healthy subjects were included in the study. Plasma ET-1 levels were found to be 10.

Dacarbazine-induced carotid artery and deep venous thrombosis in a patient with leiomyosarcoma: case report.

Thromboembolic events are a common and important cause of morbidity and mortality in cancer patients that require early diagnosis and treatment. Reports have suggested that chemotherapeutic agents may contribute to this risk. In this case report, a 60-year-old male patient on chemotherapy (dacarbazine and doxorubicin) for leiomyosarcoma with no previous history of thromboembolism developed left carotid artery thrombosis 3 days after the first cycle of chemotherapy.

Severe epistaxis in brucellosis-induced isolated thrombocytopenia: a report of two cases.

Brucellosis can present initially with its haematological findings including anaemia, leukopenia, and thrombocytopenia and may mimic primary haematological diseases. We present two patients with complaints of severe epistaxis and isolated thrombocytopenia which was initially diagnosed as idiopathic thrombocytopenic purpura but which was finally attributed to brucellosis. Their platelet count reverted to normal within 2-3 weeks of initiating antibrucellosis treatment with recovery from the disease.

Occult parathyroid carcinoma in a patient with papillary thyroid carcinoma and Hashimoto's thyroiditis.

A 47-year-old female patient with a previous history of right thyroid lobectomy was admitted to the hospital because of a 3 cm nodule in the thyroid gland. Hormonal evaluation showed subclinical hypothyroidism with serum levels of thyroid stimulating hormone slightly elevated to 4.4 microg/dl (normal: 0.

The pathological examinations of gastric mucosa in patients with Helicobacter pylori-positive and -negative pernicious anemia.

Background: The basic histopathological finding in gastric mucosa is chronic atrophic gastritis in patients with pernicious anemia.

Materials And Methods: We evaluated the frequency of Helicobacter pylori and pathological examinations of gastric mucosa in pernicious anemia (n = 30) by endoscopical findings and biopsy. The results were compared with gastric mucosa specimens of patients with H.

Bilateral transient hearing loss associated with vincristine therapy: case report.

Vincristine, adriamycin, and dexamethasone (VAD) chemotherapy protocol is first-choice treatment in newly diagnosed multiple myeloma patients in many centers. Sudden hearing loss associated with vincristine therapy is a rarely observed event in the VAD protocol. We describe a 69-year old male patient diagnosed with multiple myeloma 7 months ago who developed sudden bilateral hearing loss related to vincristine therapy.

Paroxysmal Nocturnal Haemoglobinuria in the Differential Diagnosis of Unresponsive Iron Deficiency Anemia: A Case Report.

A 16-year-old male patient who was on oral iron treatment for iron deficiency anemia for the last one year was seen at the Haematology clinic with complaints of weakness, pallor, and jaundice. A complete blood count revealed Hb of 4.2 mmol/L, Hct of 0.

Gluten-free diet improves iron-deficiency anaemia in patients with coeliac disease.

Two cases of newly-diagnosed asymptomatic coeliac disease with 3 years of unexplained severe iron-deficiency anaemia are presented. Oral iron supplementation had no effect on their serum iron levels and, therefore, had no influence on their anaemia. Upper gastrointestinal endoscopy confirmed normal macroscopic findings.

Ticlopidine-induced severe agranulocytosis after the placement of coronary artery stent--a case report.

Ticlopidine is an oral antiplatelet agent frequently utilized in the treatment of cerebrovascular disease. It is rarely associated with severe bone marrow suppression. A case of an elderly woman is reported who developed febrile agranulocytosis two months after commencing ticlopidine but who had a favorable outcome after cessation of that drug and treatment with granulocyte colony-stimulating factor (G-CSF).

Elevated serum CA-125 levels in patients with nephrotic syndrome-induced ascites.

CA-125 is a sensitive, but not a specific, tumour marker especially used in the diagnosis and follow-up of ovarian cancer. Because of the elevated levels of CA-125 encountered during the etiological investigation of nephrotic syndrome (NS) a clinical study was designed to investigate the probable relationship between elevated CA-125 levels in patients with NS, with and without ascites. Twenty-four patients with NS due to non-tumoural pathologies, aged 24 to 56 (15 females and 9 males), were investigated.

Elevated serum CA-125 levels in hemodialysis patients with peritoneal, pleural, or pericardial fluids.

Objective: Serum CA-125, an ovarian tumor marker, is used especially in the follow-up of ovarian cancer for monitoring the efficacy of therapy and for early detection of recurrence. A number of benign gynecologic as well as benign and malignant nongynecologic conditions are associated with elevated serum CA-125 levels. Malignant and nonmalignant serosal fluids were also found to be associated with high serum levels of CA-125, suggesting that the presence of fluid in the serosal cavities may stimulate its release.

Follicular thyroid cancer presenting initially with soft tissue metastasis.

Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. We report a case of an otherwise asymptomatic 58-year-old woman with follicular thyroid cancer who initially presented with a soft tissue mass on the right scapular region. An incisional biopsy specimen of soft tissue metastasis showed thyroid follicular neoplasm.

The effects of abdominal and bimanual pelvic examination and transvaginal ultrasonography on serum CA-125 levels.

The need for the early detection of ovarian cancer continues to be one of the most important issues in women's health care. The three most extensively evaluated screening methods for ovarian cancer are pelvic examination, transvaginal ultrasonography, and serum CA-125 levels. The answers to questions such as should the levels of CA-125 be measured before bimanual pelvic examination or transvaginal ultrasonography or do abdominal examinations effect the levels of CA-125 are obscure.

Idiopathic hypoparathyroidism and celiac disease in two patients with previous history of cataract.

We report two patients with idiopathic hypoparathyroidism and celiac disease. Both had undergone surgery for cataract previously. The patients presented with tetany in the absence of gastrointestinal complaints.

Delayed gastric emptying in conscious male rats following chronic estrogen and progesterone treatment.

Several clinical observations and animal experiments have led to speculation concerning the possible effects of pregnancy and pregnancy-associated sex steroids on gastrointestinal function. It was reported that estrogen increases intestinal contractile activity, while progesterone or the combination of estrogen and progesterone decreases it. In order to measure gastric emptying, a methylcellulose test meal was given orally into the stomach of conscious rats.
