Our series demonstrates an incidence of 10%; for bilateral pheochromocytoma, which is similar to that in the published reports. However, 25%; of the pheochromocytomas were ectopic. Zuckerkandl pheochromocytomas were the most common among the ectopic lesions. Rarely, these tumors present outside the abdominal cavity.
Breast cancer is the most common cause of metastatic deposits in the skeleton, and bone is the most common site of recurrence of breast cancer. Breast cancer metastasis most commonly affects the spine, ribs, pelvis, and proximal long bones; however, only 3.5% of breast cancer patients develop long-bone metastases. The humerus is the most common upper-extremity site for bony metastasis, and pathologic fractures can result. The patient in the current study presented with breast cancer and discovered to have humeral head metastasis during initial workup. The dilemma was in investigation the modality to confirm humeral head metastasis as there are many differential diagnoses with similar findings. After staging workup, the patient was treated with neoadjuvant chemotherapy followed by modified radical mastectomy and radiotherapy of the chest wall and the shoulder. The lesion in humerus was well healed.
The dubas bug (Ommatissus lybicus) (Hemiptera: Tropiduchidae) is a serious pest in date palms in several date-producing countries, including Oman. Infestation results in a severe reduction in yield and a weakening of date palm growth. In addition, egg laying, which causes injuries to date palm leaves, results in the development of necrotic lesions on the leaves. This study aimed at investigating the role of fungi in the development of necrotic leaf spots following dubas bug infestation. Leaf samples developing leaf spot symptoms were collected from dubas-bug-infested leaves, as the leaf spot symptoms were not observed on the non-infested leaves. Isolation from date palm leaves collected from 52 different farms yielded 74 fungal isolates. Molecular identification of the isolates revealed that they belonged to 31 fungal species, 16 genera, and 10 families. Among the isolated fungi, there were five Alternaria species, four species each of Penicillium and Fusarium, three species each of Cladosporium and Phaeoacremonium, and two species each of Quambalaria and Trichoderma. Out of the thirty-one fungal species, nine were pathogenic on date palm leaves and induced varying levels of leaf spot symptoms. The pathogenic species were Alternaria destruens, Fusarium fujikuroi species complex, F. humuli, F. microconidium, Cladosporium pseudochalastosporoides, C. endophyticum, Quambalaria cyanescens, Phaeoacremonium krajdenii, and P. venezuelense, which were reported for the first time as leaf spot causal agents in date palms. The study provided novel information on the effect of dubas bug infestation in date palms on the development of fungal infection and associated leaf spot symptoms.
Ventriculo-peritoneal shunt is the procedure of choice for hydrocephalus. Various complications of ventriculoperitoneal shunts were reported. Abdominal complications involving the distal tip of the catheter make the majority of the complications. In this case report we present a case of incisional hernia occurring in a patient who underwent fixation of ventriculoperitoneal shunt followed by revision of the shunt after a while
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
