An unusual case of multiple endocrine neoplasia type 1 and the role of 111In-pentetreotide scintigraphy

A 50-year-old woman is described with a very unusual combination of MEN-1 syndrome with a negative family history. At first she had been treated because of a clinically non-functioning pituitary adenoma in the maxillary sinus. Six years later a carcinoid tumour was discovered by means of 111In-pentreotide scintigraphy.

Foreign material in postoperative adhesions

OBJECTIVE

The authors determined the prevalence of foreign body granulomas in intra-abdominal adhesions in patients with a history of abdominal surgery.

PATIENTS AND METHODS

In a cross-sectional, multicenter, multinational study, adult patients with a history of one or more previous abdominal operations and scheduled for laparotomy between 1991 and 1993 were examined during surgery. Patients in whom adhesions were present were selected for study. Quantity, distribution, and quality of adhesions were scored, and adhesion samples were taken for histologic examination.

RESULTS

In 448 studied patients, the adhesions were most frequently attached to the omentum (68%) and the small bowel (67%). The amount of adhesions was significantly smaller in patients with a history of only one minor operation or one major operation, compared with those with multiple laparotomies (p < 0.001). Significantly more adhesions were found in patients with a history of adhesions at previous laparotomy (p < 0.001), with presence of abdominal abscess, hematoma, and intestinal leakage as complications after former surgery (p = 0.01, p = 0.002, and p < 0.001, respectively), and with a history of an unoperated inflammatory process (p = 0.04). Granulomas were found in 26% of all patients. Suture granulomas were found in 25% of the patients. Starch granulomas were present in 5% of the operated patients whose surgeons wore starch-containing gloves. When suture granulomas were present, the median interval between the present and the most recent previous laparotomy was 13 months. When suture granulomas were absent, this interval was significantly longer--i.e., 30 months (p = 0.002). The percentage of patients with suture granulomas decreased gradually from 37% if the previous laparotomy had occurred up to 6 months before the present operation, to 18% if the previous laparotomy had occurred more than 2 years ago (p < 0.001).

CONCLUSIONS

The number of adhesions found at laparotomy was significantly larger in patients with a history of multiple laparotomies, unoperated intra-abdominal inflammatory disease, and previous postoperative intra-abdominal complications, and when adhesions were already present at previous laparotomy. In recent adhesions, suture granulomas occurred in a large percentage. This suggests that the intra-abdominal presence of foreign material is an important cause of adhesion formation. Therefore intra-abdominal contamination with foreign material should be minimized.

Unexpected borderline malignant and malignant smooth muscle cell tumors of the uterine corpus in women treated with LH-RH analogues

In this report, two cases of uterine smooth muscle cell tumors, one of uncertain malignant potential and one clearly malignant, are described in women treated for prolonged periods with luteinizing hormone-releasing hormone (LH-RH) analogues. Due to lengthy monitoring of LH-RH therapy, surgical intervention and histologic classification of these tumors was late in the course of disease, resulting in a delay in definite treatment. The risk to these women is discussed. The effects of LH-RH analogue therapy on fibroids is reviewed. Suggestions are put forward for monitoring LH-RH analogue therapy.

Keratins 7 and 20 as diagnostic markers of carcinomas metastatic to the ovary

The most common carcinomas metastatic to the ovary that mimic ovarian primaries are colonic adenocarcinomas and endometrial carcinomas. Conventional histochemical staining procedures, even in combination with additional immunohistochemical assays, are of limited value in distinguishing between these metastases and primary ovarian carcinomas. In this study we investigated whether the application of monoclonal antibodies against keratins 7, 8, and 20 could help in differentiating between these categories. The reactivity patterns of 40 carcinomas metastatic to the ovary were compared with those of their primary carcinomas on the one hand and with various primary ovarian carcinomas and mesotheliomas on the other. Colon cancer metastatic to the ovary was keratin 7 negative and keratin 20 positive in 94% of the cases; in contrast, all primary ovarian carcinomas were keratin 7 positive and keratin 20 negative, with the exception of two cases of mucinous cystadenocarcinoma. Ovarian metastases of gastric cancer usually contained keratins 7 and 20. Metastases of endometrial cancer to the ovary and primary ovarian carcinomas usually showed similar keratin expression. We propose that keratin 7 and 20 antibodies may be of help to distinguish between primary ovarian carcinomas and carcinoma metastases in the ovary.

[Intra-abdominal adhesions and foreign-body granulomas following earlier laparotomy]

OBJECTIVE

To determine the prevalence of foreign body granulomas in intra-abdominal adhesions in patients subjected to relaparotomy.

DESIGN

Cross-sectional.

SETTING

University Hospital Rotterdam-Dijkzigt, the Netherlands.

METHOD

From July 1991 to September 1992, 119 patients were subjected to relaparotomy. Presence, distribution and quality of adhesions were scored during the relaparotomy and adhesion samples were taken for histological examination.

RESULTS

Adhesions were present in 94% of the patients; they were most frequently attached to small bowel (83%) and omentum (78%). The number of adhesions was significantly smaller in patients with a history of only one minor operation than in those with one major or multiple laparotomies. Foreign body granulomas were found in 22% of the patients with adhesions. These were caused by suture material (19%) or starch glove powder (6%); a combination of both occurred in 3% of the patients. When granulomas were present, the median interval between present and most recent laparotomy was significantly shorter than when no granulomas were found. In patients with adhesions who had had the previous operation less than 6 months previously, granulomas were present in 71%. In contrast, 13% of the patients operated upon longer than 6 months previously had granulomas.

CONCLUSIONS

In young adhesions foreign body granulomas occur in large percentages of the cases. This suggests that the intra-abdominal presence of foreign material is an important cause of adhesion formation. Therefore, intra-abdominal contamination with suture material and glove powder should be avoided.
