[Hyperplasia and adenoma of the ectopic parathyroid gland].

The frequency of the ectopic parathyroid glands has been reported to be 7-46% by anatomists or surgeons, while the proper frequency is still unknown. Recently the diagnostic methods of hyperparathyroidism have been developed, and many surgeons select total parathyroidectomy for renal hyperparathyroidism. Therefore the frequency of the ectopic glands has been supposed to be higher than that recognized previously. We investigated 97 patients with renal hyperparathyroidism, and detected 60 ectopic glands in 34 patients (35.1%). The ectopic glands existed in the mediastinum, intrathyroid, carotid sheath, post-pharynx, para-esophagus, and other regions. We describe the features of procedures for detecting ectopic glands. Using non-invasive examination, including ultrasonography, scintigraphy (T1 201-Tc 99 m), and MRI, will be a great assistance in the diagnostic procedures.

Adenoma↗

Ultrasonographic features of abdominal ectopic splenic tissue.

Ectopic splenic tissue may be congenital (an accessory spleen) or a result of traumatic autotransplantation (splenosis). The purpose of this study was to identify the features of ectopic splenic tissue in ultrasonography (US) scans. Selective spleen scintigraphy (with heat-denatured erythrocytes labelled with technetium 99m) was performed on 33 patients who had undergone splenectomy after trauma; the 25 (76%) for whom the results were positive subsequently underwent US. Of the 25 patients, 23 (92%) had one to five foci of ectopic splenic tissue; 62 of the 68 foci (91%) were in the left upper quadrant. US identified splenic tissue in 17 of the 25 patients (68%). All 44 foci visible with US were hypoechoic, and 33 of them (75%) exhibited acoustic enhancement or an incomplete hyperechoic rim or both. Nineteen of the foci revealed by US (43%) were smaller than 1 cm2. No criteria were found to permit differentiation of accessory spleens from splenosis. In three of every four patients who undergo splenectomy after trauma, ectopic splenic tissue eventually develops. Radiologists should be aware of this condition to avoid incorrectly diagnosing this ectopic tissue as metastasis, adenopathy or another solid tumour. US, in combination with selective spleen scintigraphy, permits a specific diagnosis without invasive procedures.

[Ectopic varices, a rare cause of digestive hemorrhage].

From January 1986 to September 1995, 4 patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The patients were all female, aged 30 to 65 years. The etiology of portal hypertension in these patients was alcoholic cirrhosis, cirrhosis in Wilson's disease and previous alveolar echinococcosis treated by right hepatectomy, complicated by post-operative portal thrombosis. Clinical presentation in all 4 cases was lower gastrointestinal bleeding. Diagnosis was by emergency arteriography in 3 cases; no source was found in one case with recurrent hemorrhage. The 4 patients had a history of abdominal surgery. The location of the ectopic varices was small bowel and cecum. 3 patients were treated surgically: right colectomy, partial small bowel resection and porto-caval shunt with complete lysis of adhesions. One patient was treated conservatively with emergency placement of a TIPS (transjugular intrahepatic porto-systemic shunt), with simultaneous embolization of cecal varices. Upon laparotomy, all 3 surgical cases presented ectopic varices in post-operative adhesions. In conclusion, in a patient with portal hypertension presenting with lower gastrointestinal bleeding, hemorrhage from ectopic varices should be kept in mind and investigated by arteriography. A history of abdominal surgery seems to be a predisposing factor in development of ectopic varices by adhesion formation.

Periarticular ectopic calcinosis probably due to 1 alpha-OH-vitamin D3 therapy, and successful treatment with bisphosphonate compound in a patient with systemic lupus erythematosus.

We describe the case of a 25-year-old woman who developed soft tissue ectopic nephritis. Ectopic calcinosis rarely occurs in systemic lupus erythematosus (SLE) patients. This is the first detailed case report of metastatic ectopic calcinosis, one of two categories of ectopic calcinosis, probably due to 1 alpha-OH-vitamin D3 therapy. We administered disodium 3-amino-1-hydroxypropylidene-1, 1-bisphosphonate pentahydrate, a second-generation bisphosphonate, to decrease the patient's serum calcium level, and subsequently observed a dramatic decrease in severity of the ectopic calcinosis along with decreases in both the serum calcium level and the (serum calcium level)x(serum phosphate level) index. We suggest that 1 alpha-OH vitamin D3 should be used in cases of lupus nephritis with great caution.

The value of adnexal sonographic findings in the diagnosis of ectopic pregnancy.

A prospective study of 383 patients with suspected ectopic pregnancy was carried out at Yale-New Haven Hospital to determine the value of adnexal sonographic findings in the diagnosis of ectopic pregnancy. In patients with adnexal sonographic results and human chorionic gonadotropin titers less than 6000 mIU/ml (n = 220), the presence of a noncystic mass had a positive predictive value of 83%, and the presence of a cystic mass had a positive predictive value of 35%. The combination of a noncystic mass and fluid in the cul-de-sac (found in 22% of all patients with ectopic gestations) was the best predictor of an ectopic pregnancy with a 94% positive predictive value. It is suggested that the demonstration of a non-cystic mass, alone or in the presence of fluid in the cul-de-sac, be used as an indication for diagnostic laparoscopy.

Ectopic pregnancy and prior induced abortion.

As part of the Women's Health Study, a case-control study conducted in nine cities in the United States, women hospitalized with an ectopic pregnancy and women hospitalized with non-gynecologic, medical or surgical diagnoses were interviewed concerning past reproductive history. There were 462 women meeting eligibility criteria in the ectopic pregnancy case group and 2326 women meeting the criteria for the control group. After adjustment for a number of possible confounders, the relative risk of ectopic pregnancy for women with a history of one induced abortion was 1.0 (95% confidence limits: 0.5 to 1.8) and was 0.9 (95% confidence limits: 0.8 to 1.1) for women with a history of two or more prior induced abortions. These results suggest that prior induced abortion does not significantly increase the risk of subsequent ectopic pregnancy.

Background factors of ectopic pregnancy. I. Frequency distribution in a case-control study.

Two hundred and five patients with ectopic pregnancy in a well-defined Swedish population were interviewed with respect to prior disease and pregnancy histories as well as various constitutional and socioeconomic factors. The results were compared with those of two control groups, i.e. 110 early pregnant women intending to continue the gestation to term as well as 101 women seeking voluntary interruption of pregnancy. The results provide evidence that several may be involved in the etiology of ectopic pregnancy, including abdominal (or pelvic) surgery, previous ectopic pregnancy and pelvic inflammatory disease. Furthermore, a history of infertility is strongly correlated to ectopic pregnancy. On the other hand, there is no evidence that uncomplicated spontaneous or induced abortion, parity or marital status are important factors.

Ectopic pregnancy.

The diagnosis of ectopic pregnancy has become precise and reliable. Consequently, the management of ectopic pregnancy has progressed to the point where the physician is often able to preserve fertility. Therefore, conservative surgery is indicated if the patient desires future fertility and conditions are appropriate. The combination of ultrasound, beta-hCG pregnancy testing, and laparoscopy has led to a rising incidence of diagnosed ectopic pregnancy prior to rupture. This has greatly facilitated the use of the conservative approach to the management of tubal pregnancy. Although ectopic pregnancy can be diagnosed early and managed conservatively, it is, and will remain a potentially life-threatening disease and must be approached as such. Table 3 summarizes our proposed surgical management of tubal pregnancy. Table 4 summarizes the results of conservative surgery for tubal pregnancy.

Chorionic Gonadotropin↗

Ectopic secretion of peptides of the proopiomelanocortin family.

A wide spectrum of clinical and biochemical presentations characterize ectopic POMC syndrome. It is presently postulated that ectopic POMC production results from increased expression of the activity of a POMC gene normally occurring in a variety of tissues outside the pituitary gland. The syndrome is rapidly progressive and is characterized by severe clinical manifestations in patients with a more aggressively developing oat cell carcinoma of the lung. However, in patients with slower growing nonpituitary tumors, the presentation may overlap that seen in patients with pituitary ACTH-dependent Cushing's syndrome. In cases in which the biochemical testing results overlap with those seen in pituitary ACTH-dependent disease, a combination of lack of suppression with high-dose dexamethasone and absent response to CRH stimulation greatly increases the diagnostic accuracy. Abnormal alternative processing of POMC in nonpituitary neoplasms may render unusual POMC-derived peptides that could be used as markers in the diagnosis and follow-up of patients with this syndrome. The prognosis of patients afflicted with ectopic POMC syndrome is largely determined by the nature of the underlying tumor. However, the clinical course can be greatly modified by control of the metabolic manifestations of hypercortisolemia. A variety of surgical and pharmacologic options are available, including adrenalectomy and the use of adrenal inhibitors. Cushing's syndrome of long duration, the finding of ectopic pituitary adenomas, and the combined secretion of CRH and POMC by nonpituitary tumors constitute interesting variants of the classic picture.

ACTH Syndrome, Ectopic↗

Tubal conservation with ectopic gestations. A reappraisal.

Ectopic pregnancies have shown an increasing trend during the past decade. Factors that appear to be responsible are the intrauterine device (IUD), fallopian tube surgery (ligation reversals, reconstructive tuboplasty), and more effective antibiotics against pelvic inflammatory disease (precluding radical pelvic surgery). Our ability to diagnose an ectopic pregnancy at an earlier gestation (prior to rupture) through the use of highly sensitive pregnancy tests (Beta-HCG), ultrasonography, and diagnostic laparoscopy, has significantly altered our approach in treatment. Because these ectopic gestations are seen in a younger population, older nulliparous patients, and patients who desire future fertility, earlier diagnosis precludes an emergency approach to a now-elective procedure. In this paper, we will explore the pros and cons of conservative management for ectopic pregnancies, emphasizing present day evaluation and microsurgical approaches for repair.

Ectopic adrenocorticotrophic (ACTH) syndrome and small cell carcinoma of the lung-assessment of clinical implications in patients on combination chemotherapy.

Small cell carcinoma of the lung is the tumor most commonly associated with ectopic ACTH production and hypercortisolism. The relationship between this paraneoplastic endocrine syndrome and the clinical course of the tumor is examined in this review of patients with the ectopic ACTH syndrome and small cell carcinoma seen at The Johns Hopkins Oncology Center between 1973 and 1979. Five of 157 (3.2%) patients with small cell carcinoma were clinically diagnosed as having the ectopic ACTH syndrome. The onset of this endocrine syndrome appeared to coincide with a more aggressive phase of the course of small cell carcinoma. Further analysis of these cases suggests that the development of the ectopic ACTH syndrome may reflect changes in cell populations within the tumor and/or alterations in tumor behavior with time and perhaps with the effects of drug therapy.

Management of patients with small cell carcinoma and the syndrome of ectopic corticotropin secretion.

BACKGROUND: Small cell carcinoma (SCC) associated with clinical evidence of tumor corticotropin (ACTH) production is common, and management of this syndrome is difficult. The purpose of this retrospective analysis is to describe clinical features, prognosis, and treatment results in patients with SCC and the syndrome of ectopic ACTH secretion to permit formulation of management guidelines for these patients. METHODS: Using tumor registry data and chart review, the authors identified patients with SCC and ectopic ACTH secretion treated over 11 years at two large teaching hospitals. They recorded clinical and laboratory data regarding the patients' tumors and their endocrine syndrome along with results of treatment for the malignancy and the hypercortisolism. RESULTS: Ten patients with SCC and ectopic ACTH secretion were identified. These patients were initially seen with adverse prognostic features, including elevations of serum lactate dehydrogenase and extensive stage disease. Cytotoxic chemotherapy and standard doses of anti-adrenal medications rarely controlled the paraneoplastic syndrome. Bacterial or opportunistic infections, although not neutropenic, developed in most patients. Median survival of patients diagnosed with the paraneoplastic syndrome at the same time as the initial diagnosis of cancer was 4 months. However, three patients whose cortisol secretion was controlled survived longer than 6 months. CONCLUSIONS: Patients with SCC and ectopic ACTH syndrome have a poor prognosis. However, in the minority of patients whose hypercortisolism can be controlled with cytotoxic chemotherapy combined with treatment to inhibit cortisol biosynthesis, effective palliation can be achieved.

Criteria for transvaginal sonographic diagnosis of ectopic pregnancy.

Transvaginal ultrasonography was performed in 1150 patients suspected of having an ectopic gestation. The criteria for transvaginal sonographic diagnosis of ectopic pregnancy were established by targeted scanning of the pelvic organs and spaces. Sonographic assessment of tubal pregnancy and its differential diagnosis were based on six criteria: (1) the presence or absence of gestational structures within the fallopian tube, (2) the presence or absence of amorphous material in a dilated fallopian tube, (3) the presence or absence of indirect signs of ectopic pregnancy within the pelvis, (4) the echogenicity of a suspected finding relative to the ovary, (5) the presence or absence of flow (of lacunar origin) within the suspected sonographic finding, and (6) the relationship of a suspected sonographic sign to an intentionally displaced ovary. The latter 3 criteria help differentiate between tubal gestation and a corpus luteum. We believe these diagnostic criteria should be applied when performing transvaginal sonographic scanning of patients suspected of having an ectopic gestation.

Accuracy of transvaginal ultrasonography for detection of hematosalpinx in ectopic pregnancy.

The transvaginal approach has significantly improved the accuracy of ultrasonography for the detection of ectopic pregnancy. However, there has been limited emphasis given to determining the sensitivity of ultrasonography when a hematosalpinx was used as a specific finding to identify an ectopic pregnancy. The sensitivity of transvaginal ultrasonography was evaluated for the detection of a hematosalpinx defined as an "echogenic homogeneous or inhomogeneous, rounded or elongated structure" in a group of patients with surgically proven ectopic pregnancy. Retrospectively, transvaginal ultrasonography showed a hematosalpinx in 16 out of 18 (88.8%) tubal pregnancies. In 6/6 (100%) patients with a ruptured tube and 10/12 (83.3%) patients with an unruptured tube, a hematosalpinx was detected sonographically. A gestational sac with a live embryo was seen in 26.3% of these patients. The significance of identifying a hematosalpinx, predictability of rupture and implication in the treatment of ectopic pregnancy are discussed.

Small cell carcinoma of the vagina causing Cushing's syndrome by ectopic production and secretion of ACTH: a case report.

BACKGROUND: Small cell carcinomas of pulmonary or extrapulmonary origin are neuroendocrine tumors classically associated with ectopic hormone production, particularly ACTH secretion resulting in Cushing's syndrome. However, ectopic Cushing's syndrome has not previously been reported in the setting of small cell carcinoma of the vagina. METHODS: A primary vaginal tumor with hepatic metastases was evaluated with light microscopy. Serum cortisol and plasma ACTH levels were evaluated by radioimmunoassay and immunoradiometric assay, respectively, during a standard high-dose (8 mg) overnight dexamethasone suppression test. RESULTS: Vaginal small cell carcinoma with hepatic metastases was demonstrated. Electrolyte abnormalities, elevated cortisol and ACTH levels, and failure to suppress ACTH secretion during high-dose dexamethasone administration confirmed the diagnosis of ectopic ACTH syndrome. CONCLUSIONS: This case report establishes a clinical association between vaginal small cell carcinoma and ectopic Cushing's syndrome, confirming the neuroendocrine potential of this malignancy and features common to small cell neoplasms originating in other sites.

Catheter ablation of junctional ectopic tachycardia in children, with preservation of atrioventricular conduction.

BACKGROUND: Idiopathic junctional ectopic tachycardia is a rare arrhythmia in children. Several studies have demonstrated that drug therapy is often ineffective and sometimes the only achieved effect is rate control. Early presentation and frequent recurrence are associated with adverse outcome. PATIENTS AND METHODS: Three consecutive children, aged 9, 7 and 12 years respectively, underwent radiofrequency catheter ablation for junctional ectopic tachycardia, after having failed antiarrhythmic drug therapy. The entire His bundle was plotted out and marked, using the Localisa navigation system. The arrhythmia was readily and repeatedly inducible using intravenous isoprenaline infusion and the site of earliest retrograde conduction during tachycardia could be assessed. Ablations were performed in sinus rhythm, empirically targeting the site of earliest retrograde conduction during tachycardia. RESULTS: This approach was successful in abolishing tachyarrhythmia in the first two patients, in whom the successful ablation site was located superoparaseptally. In the third patient, junctional ectopic tachycardia was inducible, despite abolishing retrograde atrial activation, in a septal location on the tricuspid valve annulus. Further ablations in the superoparaseptal region, closer to the His bundle, were successful in rendering tachyarrhythmia noninducible. Over a median follow-up of 10 months, none of the patients has had recurrence of arrhythmia, despite discontinuing all antiarrhythmic medications. CONCLUSIONS: Radio frequency catheter ablation of junctional ectopic tachycardia is feasible with preservation of atrioventricular conduction.

Treatment of ectopic pregnancy with a single intramuscular dose of methotrexate.

This study evaluates the outcome of unruptured ectopic pregnancies treated with single-dose intramuscular methotrexate injection. There were 77 women with unruptured non-laparoscopically diagnosed ectopic pregnancies who were prospectively followed after receiving a single dose of 50 mg/m2 intramuscular methotrexate. Diagnosis required transvaginal ultrasound and serial quantification of beta subunit of human chorionic gonadotropin (betahCG). A repeat dose was given if the weekly drop of betahCG was less than 30%. Therapy was considered successful if complete resolution of betahCG to a level below 25 IU/L was achieved without surgical intervention. Treatment in 73 (95%) cases was successful. The mean pre-treatment level of betahCG was 2592 +/- 3771 IU/L (177-15000 IU/L), the mean diameter of ectopic mass was 2.4 +/- 1.0 cm (1.7-3.5 cm). The average resolution period was 3.2 +/- 1.0 weeks (1-6 weeks) and this significantly correlated with the pre-treatment betahCG level. With strict criteria of inclusion and follow-up, single-dose intramuscular methotrexate is a successful method for the treatment of selected cases of ectopic pregnancy.

Single-dose methotrexate for the treatment of unruptured ectopic pregnancy.

OBJECTIVE: The objective of this study was to review our experience with single dose intramuscular methotrexate (MTX) for the treatment of ectopic pregnancy and to evaluate major confounding factors that relate to the success of therapy. PATIENTS AND METHODS: The selection criteria were patients who had a stable hemodynamic status and an ectopic gestational mass of <4 cm. on ultrasound. Patients were not excluded from MTX therapy either by a baseline serum beta-hCG titer or by the presence of fetal cardiac activity demonstrated on ultrasonography. Thirty- four of 86 patients diagnosed with ectopic pregnancy and treated with single-dose MTX between July 1999 and November 2001 were reviewed retrospectively. RESULTS: The mean pre-treatment beta-hCG level was 2,490+/-2,912 mIU/ml. Twenty-two patients (73.3%) were successfully treated with a single-dose of MTX. Eight patients (26.6%) required a second dose 1 week after the first injection and 2 patients received three doses. Thirty of the 34 patients (88%) were successfully treated with MTX. The mean pre-treatment beta-hCG level was significantly lower in patients who were successfully treated with MTX than in patients who failed MTX therapy (1,932+/-2,361 mIU/ml vs. 6,955+/-2,690 mIU/ml respectively, p<0.05). The mean pre-treatment serum beta-hCG level was higher in patients who had a second MTX injection as compared to patients who were successfully treated with a single injection of MTX (3,272+/-3,551 mIU/ml vs. 1,280+/-2,273 mIU/ml respectively, p>0.05). The mean time to resolution of beta-hCG was 26.5 days (10 to 37 days) with MTX. All 3 patients who failed medical therapy had beta-hCG level >4,000 mIU/ml and 2 of them had positive fetal cardiac activity. CONCLUSION: In conclusion, this study showed that medical treatment of ectopic pregnancy with systemic single-dose methotrexate seems to be an option for some patients with unruptured tubal pregnancy.
