RESUMO

A full-term male neonate presented with a left sided cervical lump at the level of the thyroid gland. Magnetic resonance imaging (MRI) showed a benign heterogeneous solid mass with lobulated margins. The tumor underwent complete excision. Histology revealed the diagnosis of chondromesenchymal hamartoma in ectopic thyroid tissue.

RESUMO

The combination of obstructive sleep apnea syndrome and vascular malformation within the head and neck region is a rare condition, and interestingly, only a few cases have recently been published. Propagation of the vascular mass to the larynx and pharynx can cause breathing and swallowing difficulties. Due to these sypmtoms, examination and initiation of appropriate therapy for such patients are indeed challenging. We reviewed the literature available and present our case of a 64 year old woman emphasizing the complaints of sleep apnea syndrome and vascular malformation of the face and neck region. Polygraphic examination detected severe obstructive sleep apnea syndrome. The MR examination of the neck revealed extensive vascular mass narrowing the pharyngo-laryngeal region, thereby causing temporal bone destruction on the right side with intracranial propagation. ENT examination demonstrated significant narrowing of the pharyngeal lumen and the laryngeal aditus caused by multiple hemangiomas. CPAP titration showed the minimalization of the apnea-hypopnea index on the effective pressure level. Regular CPAP usage resulted in diminishing a majority of the patient's complaints. Our examination clearly demonstrates, obstructive sleep apnea syndrome coupled with significantly obstructing vascular malformation in the head and neck region can be effectively treated safely with a CPAP device, if surgical therapy is not possible. We summarized our findings and the data available in the literature to set up recommendations for the appropriate examination and therapy (including mask fit, etc.) of vascular malformations and hemangiomas causing pharyngo-laryngeal obstruction.

RESUMO

PURPOSE: To elucidate the impact of renal parenchymal loss and the ischemic reperfusion injury (RI) on the renal function after laparoscopic partial nephrectomy (LPN) under warm ischemia (WI). METHODS: Thirty-five patients with a single polar renal mass ≤4 cm and normal contralateral kidney underwent LPN. Transperitoneal LPN with WI using en bloc hilar occlusion was performed. The total differential renal function (T-DRF) using 99mTc-dimercaptosuccinic acid was evaluated preoperatively and postoperatively over a period of 1 year. A special region of interest (ROI) was selected on the non-tumorous pole of the involved kidney, and was compared with the same ROI in the contralateral kidney. The latter comparison was defined as partial differential renal function (P-DRF). Any postoperative decline in the P-DRF of the operated kidney was attributed to the RI. Subtraction of the P-DRF decline from the T-DRF decline was attributed to the parenchymal loss caused by the resection of the tumor and suturing of the normal parenchyma. RESULTS: The mean WI time was 22 min, and the mean weight of resected specimen was 18 g. The mean postoperative eGFR declined to 87 ml/min/1.73 m2 from its baseline mean value of 97 ml/min/1.73 m2 (p value = 0.075). Mean postoperative T-DRF and P-DRF of the operated kidney declined by 7 and 3 %, respectively. CONCLUSIONS: After LPN of small renal mass, decline in renal function is primarily attributed to parenchymal loss caused by tumor resection and suturing of the normal parenchyma rather than the RI.
