Endoscopic Treatment of Sphenoid Sinus Mucocele: Case Report and Surgical Considerations.

Introduction: The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium.

Objective: To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach.

Case Report: 59-year-old male patient with history of increasing frontoorbital, bilateral, fluctuating headache and exophthalmos.

Ictal-interictal continuum: A proposed treatment algorithm.

The ictal-interictal continuum (IIC) is characterized by periodic and/or rhythmic EEG patterns that occur with relative high frequency in critically ill patients. Several studies have reported that some patterns seen within the continuum are independently associated with poor outcome. However there is no consensus regarding when to treat them or how aggressive treatment should be.

[Staghorn calculi. Combined treatment with percutaneous nephrolithotripsy and extracorporeal lithotripsy].

We present our experience in 61 patients with partial or complete staghorn stone who underwent combined treatment with PCN and ESWL. We excluded the cases with an additional factor complicating staghorn stone, such as horseshoe kidney, severe ectopic, mal-rotated or high, with pyeloureteral junction stricture, etc. The patients were submitted to 72 PCN and 113 ESWL sessions, 5 percutaneous nephrostomies prior to PCN and 5 ureteroscopy procedures to remove post-ESWL obstruction.

Chronic urticaria: humoral and clinical diagnosis of its morphological variables.

Thirty adult patients with a diagnosis of chronic urticaria were attended as outpatients at the Allergology Service, Clinical Surgical Hospital "Hnos. Ameijeiras". An accurate clinical history was made, humoral parameters such as erythrosedimentation, total eosinophil count, serum levels of immunoglobulins and complement fractions were measured, and a skin biopsy was done.

Some aspects of the allergy to cow's milk. Morphological alterations of the jejunal mucosa.

Forty-four patients were studied at the Allergology and Pediatric Outpatient Services of the "Centro Habana" Pediatric Hospital. Allergy to cow's milk was demonstrated in these children by means of a detailed medical history, suppression diet and reexposition, lactose tolerance test, intradermal skin tests with casein extracts and the remaining proteins of cow's milk; finally, a careful study of the jejunal mucosas by means of biopsy was carried out, according to Townley and Barnes' method with a Crosby capsule. The skin reactivity was evident in children with allergy to cow's milk with tested extracts, mainly casein; in the control group this result was scarce or nil.

Immunology of atopic dermatitis.
