Background. Presence of myoglobinuria, particularly in the early phases of renal failure, and elevation of creatinine kinase are seen to correlate with the development of acute renal failure. Aim. To evaluate the efficiency of serum creatine kinase (CK) and urine myoglobin in assessing development of renal failure. Materials and Method. We prospectively studied trauma patients over a period of 3 months. Samples of 107 patients were routinely analyzed on the 1st, 3rd, and 5th days post trauma, for myoglobinuria and serum CK concentration. Results. 107 patients with median age 28 (4–83) yrs were studied, of which 83.2% were males. 56% had head injury, and 17.1% had high injury severity (ISS > 24). Incidence of renal failure was 9.3%. Myoglobinuria was present in 57 patients on admission, 33 on 3rd day and 22 on the 5th day. The association of myoglobinuria with renal failure was statistically insignificant. The cutoff values of serum CK on the 1st, 3rd, and 5th days were ≥1320 IU/L, ≥1146 IU/L, and ≥1754 IU/L, respectively. Mortality rate was 24 (22.4%), of which 6 had renal failure. Conclusion. Myoglobin is clinically insignificant in the detection of renal failure; serum CK is a sensitive predicting marker for the progression of renal failure following traumatic injury.
Dysembryoplastic neuroepithelial tumor (DNET) is a recently described, morphologically unique, and surgically curable low-grade brain tumor which is included in the latest WHO classification as neuronal and mixed neuronal-glial tumor. It is usually seen in children and young adults. The importance of this particular entity is that it is a surgically curable neuroepithelial neoplasm. When recognized, the need for adjuvant radiotherapy and chemotherapy is obviated. We hereby present a case report of an 8-year-old male child who presented with intractable seizures and parieto-occipital space occupying lesion. Histologically, the tumor exhibited features of WHO grade I dysembryoplastic neuroepithelial tumor which was further confirmed by immunohistochemistry.
Intentional subcutaneous injection of mercury by mentally healthy children is rare. Usually, it is seen as a part of suicidal attempt in severely depressed patients or by athletes to enhance their performance. We report a case of a 15-year-old child, inspired by a movie, who deliberately self-injected mercury subcutaneously into his forearm that led to the formation of a non-healing ulcer. Histopathology of the biopsy confirmed the diagnosis. A surgical procedure was thereby performed to treat the ulcer and reduce the blood and urinary levels of mercury. However, the patient did not develop clinical signs of chronic poisoning, proving that subcutaneous mercury injection has a low risk of systemic toxicity, and that histopathology plays an important role in diagnosis.
Background: Cervical thymic cysts are uncommon lesions, rarely considered in the differential diagnosis of neck cysts in children. Case presentation: We report a rare case of multiloculated thymic cyst in an 8-year-old boy on the right side of the neck. Perioperative diagnosis was a cystic hygroma. Macroscopic examination showed a cystic mass measuring 6.5 cm in total length. Histopathology of the excised specimen revealed thymic tissue with prominent Hassall's corpuscles associated with multiloculated cyst. The cyst wall is bordered by a flattened or multilayered epithelium, often abraded. Conclusion: This case is presented here for its rarity and should be included in the differential diagnosis of neck masses in children. So, it's a lesion to be well aware of, particularly by pathologists.
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.
