Spontaneous intracranial hypotension (SICH) is an entity, which is secondary to iatrogenic manipulation and breaching of dura. Postural headache in patients should be suspected, cranial magnetic resonance imaging (MRI) is essential for precise diagnosis. Hallmark of MRI is regular shape of pachymeningeal gadolinium enhancement and subdural effusion.

Purpose: The aim of the present study was to evaluate the radioprotective efficacy of L-carnitine (LC) in growing bones in comparison to amifostine.

Materials And Methods: Sixty two-week-old Wistar albino rats were randomly assigned to six equal groups: Group 1, control (CONT); Group 2, irradiation alone (RT); Group 3, amifostine plus irradiation (AMI+ RT); Group 4, L-carnitine plus irradiation (LC+ RT); Group 5, amifostine alone (AMI); Group 6, L-carnitine alone (LC). The rats in the AMI+ RT, LC+ RT and RT groups were irradiated individually with a single dose of 20 Gy to the left femur.

Solitary fibrous tumor (SFT) of the pleura is an uncommon neoplasm with non-specific symptoms and non-pathognomonical radiological findings. Surgery allows establishment of a definitive diagnosis as well as a cure of the disease. The role of radiotherapy or chemotherapy in the management of the disease is unclear because of the rarity of the disease and the successful results of the surgical treatment.

Background: To identify the candidates for prophylactic cranial radiotherapy (PCI) among the patients with early and advanced-stage breast cancer.

Methods: The demographic, pathologic and clinical features and survival results of 182 brain metastatic breast cancer patients treated with cranial radiotherapy were examined.

Results: Early stage patients who progressed with isolated brain metastasis had longer survival (13 months vs.

Purpose: To assess the degree of protective effects of amifostine on kidney functions via semiquantitative static renal scintigraphy and histopathologic analysis.

Material And Methods: 30 female albino rats were divided into three equal groups as control (CL), radiotherapy alone (RT), and radiotherapy + amifostine (RT+AMI). The animals in the CL and RT groups were given phosphate-buffered saline, whereas the animals in the RT+AMI group received amifostine (200 mg/kg) by intraperitoneal injection 30 min before irradiation.

Tumours that metastasise to groin nodes most frequently originate in genital and reproductive organs, skin, rectum or anus, or urinary bladder. However, rare cases of inguinal metastases from tumours above the diaphragm have been reported and only three of them had an inguinal metastasis which was recognised antemortem and reported in detail in the English medical literature. The primary tumours of these cases were malignant mesothelioma, salivary duct and breast carcinoma.

Adenoid cystic carcinoma is the second most common malignancy of the major and minor salivary glands after mucoepidemoid carcinoma. The risk of distant metastases is approximately 20-50%. Although bone, the central nervous system and the other organs may become involved, the lungs are favored sites for metastases.

The term 'radiation recall' describes an acute inflammatory reaction in previously irradiated areas after the administration of certain inciting systemic agents. It was first described in 1959 by D'Angio that dermatitis is related to the application of actinomycin D on the skin. Though this reaction occurs frequently on the skin, it may also be seen in the oral mucosa, the larynx, esophagus, small intestine, lungs, muscle tissue, and brain.

Various remote effects of cancer or paraneoplastic syndromes (PNS) are common in lung cancer, and may be the manifestation of the disease or its recurrence. The symptoms may be endocrine, neuromuscular or musculoskeletal, cardiovascular, cutaneous, hematologic, gastrointestinal, renal, or miscellaneous in nature. Since the symptoms of paraneoplastic syndromes may occur before the local symptoms of the primary tumor, it might be helpful in the early diagnosis of malignancy.

Familial osteosarcoma is a rare hereditary disease. We present a 37-year-old father and a 17-year-old son who developed osteosarcoma in the left and right distal femurs, respectively, at a three-year interval. They were treated with chemotherapy followed by surgery.
