Role of transvaginal sonography in the detection of endometriomata.

Endometriosis is a common cause of pelvic pain and infertility in young women. Transvaginal sonography is major means for diagnosing ovarian In our study, we scanned 60 patients with endometriomata who underwent laparotomy or laparoscopy. We compared preoperative ultrasonographic diagnosis with histological reports. The sonographic criteria for the diagnosis of endometriomata were (1) cystic structure with low, homogeneous echogenicity and (2) thick cystic wall with regular margins. In 50 patients, sonography suggested an endometrioma. In 47 cases, the diagnosis was correct. The false-positive cases were all caused by cystic teratomas with a homogeneous sonographic pattern. Ten false-negative cases were diagnosed by ultra-sonography as functional ovarian cysts (5), teratomas (3), and benign ovarian cystoma (1). Only 1 case of a 5-mm endometrioma was demonstrated by laparoscopy but not by TVS. The sensitivity of TVS for diagnosing endometriomata was 82.4% and specificity 97.7%; the positive and negative predictive values were 94% and 92.8%, respectively. The diagnostic accuracy of TVS was 93%. In our experience, TVS is a very specific means for diagnosing endometriomata when the typical pattern is detected; however, the sensitivity of the technique needs to be improved.

Massive osteolysis of skull bones secondary to lymphangioma of paranasal sinuses and mastoid sinus: report of two cases in children.

Massive osteolysis (MO) is a rare condition in which progressive localized bone tissue resorption is associated with proliferating thin-walled vessels in the absence of inflammation. Rare cases have been reported to occur in the skull. This paper describes two patients with MO who presented with massive assymetric swelling of the skull. This was associated with extensive enlargement of the paranasal sinuses (frontal, ethmoidal, and sphenoidal in one and the mastoid air cells in the other). The second patient developed subcutaneous emphysema on several occasions and the Valsalva maneuver increased the swelling, indicating transmission of the air from the nasopharynx to the mastoid cells and from there to the subcutaneous tissue. In the first patient, the sinus mucosa was shown to be involved by an extensive lymphangioma, and a similar change was seen in the mastoid air cells (patient 2). We are proposing that MO of these two patients resulted from bone resorption due to progressive extension of sinus mucous lymphangiomata.

Pancreatic enzyme therapy and nutritional status of outpatients with chronic pancreatitis.

Patients with chronic pancreatitis are at risk for poor nutritional status. The two major clinical features of chronic pancreatitis are abdominal pain and maldigestion, both resulting in malnutrition. Abdominal pain often results in decreased oral intake, and decreased enzyme production results in maldigestion. Enzyme therapy often is included in treating chronic pancreatitis. There is limited data on the nutritional assessment of outpatients with chronic pancreatitis, and the efficacy of the use of enzyme therapy remains controversial. Serum albumin level and measurement of ideal body weight are two simple measures of nutritional status that can be obtained by gastroenterology nurses. A retrospective chart review was done of patients seen in our outpatient clinic for management of chronic pancreatitis. Serum albumin levels, an indicator of protein calorie malnutrition, were reviewed for 34 patients. Thirty-three percent of these patients were found to have mild-to-moderate protein calorie malnutrition as evidenced by low serum albumin levels. Enzyme therapy information was reviewed for 33 patients. Patients receiving enzyme therapy had better nutritional status based on both serum albumin levels and percent of ideal body weight. Gastroenterology nurses can be instrumental in the recognition and treatment of nutritional deficiencies in chronic pancreatitis.
