[en] Taxonomy of the causal fungus of mango malformation (MM) disease has passed through different phases. The fungus at first named as F. moniliforme was elevated to species level as F. subglutinans. Two new species viz. Fusarium mangiferae and F. sterilihyphosum Britz. found responsible for causing MM have been characterized in South Africa in the year 2002. Presence of F. mangiferae in Asian clade emphasized the need to confirm the specific species in the mango orchards of Pakistan. The assay of malformed parts of mango varieties obtained from five districts of the Punjab province of Pakistan revealed the association of four fungi viz., F. mangiferae, F. pallidoroseum, F. equiseti and Alternaria alternata while F. mangiferae proved to be the major infecting fungus. The colonies of F. mangiferae were tinged with purple and rosy buff color on Potato dextrose agar (PDA) medium. Macroconidia were four celled with dorsal and ventral surfaces almost parallel. Maximum within tissue infection (40.53%) in five districts was caused by F. mangiferae. The present studies reveal the infectivity and dominant association of F. mangiferae with malformed tissues of diverse origins. (author)
[en] Migration of an implantable port catheter tip is one of the well-known complications of this procedure, but the etiology of this problem is not clear. We describe here a case of migration of the tip of a port catheter from the right atrium to the right axillary vein in a patient with severe cough. Coughing was suggested for this case as the cause of the catheter tip migration. We corrected the position of the catheter tip via transfemoral snaring
[en] Melorheostosis is a rare bone dysplasia of unknown etiology that usually affects a single limb and is characterized by cortical thickening, with a flowing candle wax appearance, extending vertically along the surface of the long bone. We report a case of polyostotic melorheostosis symmetrically involving multiple flat bones, ribs, and the scapulas. This is the first case of melorheostosis symmetrically involving multiple flat bones
[en] Hepatocellular carcinoma in childhood and adolescents is rare and hi gly aggressive type of tumor. It differs from adult hepatocellular carcinoma in epidemiology, etiology, clinical symptoms and biology features. Cornerstone of therapy is radical surgical resection of the tumor. If it is not possible to perform, patient is indicated for early primary liver transplantation. The role of chemotherapy is very limited, biology therapy is still investigational for children and adolescents. (author)
[en] Transcatheter embolization was done in 15 patients with various diseases at department of radiology, Seoul National University Hospital from September 1978 ti July 1983 using absolute ethanol, autologous blood clots and gelfoam particles as embolic agents. The results were as follows 1. Successful embolization were done in 14 of 15 cases. (Success rate: 93%). 2. Most of complication was post-embolization syndrome such as fever, nausea, pain but minimal. Serious complication was very little. 3. Transcatheter embolization appears to be highly valuable adjuvant therapy in debulking of preoperative and inoperable hypervascular mass or treatment of bleeding from various etiology
[en] The ophthalmic artery usually arises from the anteromedial or superomedial aspect of the internal carotid artery. Rarely does it arise from the medial or posteromedial aspect of the internal carotid artery. In this paper, the authors report two cases of aneurysm and infundibular dilatation found at unusual sites of origin in the ophthalmic artery and review the literature about possible etiologies contributing to the anatomic variations.
[en] Bifid mandibular condyle (BMC) is an uncommon morphological variant of the mandibular condyle. Although authors have proposed various etiologies for BMC, no consensus has emerged. In addition, varying findings have been reported regarding the epidemiological parameters of BMC (e.g., prevalence, gender ratio, and age), possibly due to its low incidence. BMC is occasionally associated with symptoms of the temporomandibular joint, such as ankylosis, pain, and trismus; however, it is difficult to detect this condition on conventional radiographs. This study reports a case of BMC with radiographic findings, and reviews the literature on the epidemiology of BMC
[en] Chylothorax is a rare clinical entity characterized by a milky white aspirate with increased triglyceride levels. The commonest aetiology is malignancy and trauma. Pulmonary tuberculosis is an extremely rare cause of chylothorax. Two children with chylothorax and pulmonary tuberculosis are described. One child had bilateral and the other unilateral chylous effusions. Extensive mediastinal and hilar lymphadenopathy was demonstrated. Diseased lymph nodes may infiltrate other intrathoracic structures such as the thoracic duct, and they can also obstruct the cisterna chyli and thoracic duct. A possible explanation for the development of a chylothorax in our patients is obstruction of the thoracic duct by tuberculous lymphadenopathy with subsequent increase in pressure in the surrounding lymphatic system and leaking of chyle into the pleural space.

[en] The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or cusp tip on the panoramic radiograph. Overbite and overjet were measured from the pre- and post-treatment lateral cephalometric radiographs. The root resorption of each tooth and the factors of malocclusion were analyzed with an analysis of variance. A paired t test was performed to compare the mean amount of root resorption between male and female, between extraction and non-extraction cases, and between surgery and non-surgery groups. Correlation coefficients were measured to assess the relationship between the amount of root resorption and the age in which the orthodontic treatment started, the degree of changes in overbite and overjet, and the duration of treatment. Maxillary central incisor was the most resorbed tooth, followed by the maxillary lateral incisor, the mandibular central incisor, and the mandibular lateral incisor. The history of tooth extraction was significantly associated with the root resorption. The duration of orthodontic treatment was positively correlated with the amount of root resorption. These findings show that orthodontic treatment should be carefully performed in patients who need the treatment for a long period and with a pre-treatment extraction of teeth.
[en] Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is a relatively common benign tumor of the skeleton, occurring most often in the metaphyseal region of long bone. However, it is rare in the facial bones. Reported foci in the mandible were the condyle, coronoid process, and symphysis region. Synovial chondromatosis is an uncommon benign condition of unknown etiology which affects the articular joints. Foci of cartilage develop through metaplasia in the underlying connective tissue of the synovial membrane. These cartilagenous foci and fragments may undergo calcification and ossification. We experienced 4 patients with abnormal appearance of mandibular condyle. This report describes 3 cases of osteocondroma and 1 case of synovial chondromatosis of the mandibular condyle with review of the literature
