Diagnostics in assisted human reproduction.

The World Health Organization (WHO) estimates that 50-80 x 10(6) couples in the world are infertile, i.e. 7-15% of all couples of reproductive age (15-45 years old). The term infertility refers to couples who have been unable to conceive children for at least 1 year of regular unprotected intercourse. Although the frequency and origin of infertility varies, approximately 40-60% of the aetiology of infertility in the population studied is due to female causes. The introduction of assisted reproduction techniques, which offer couples the best opportunities for pregnancy, has opened a vast field of knowledge in reproductive biology. The medical history must be taken meticulously, with enough time to obtain the largest possible amount of relevant information. It is recommended that both partners be included in the initial work-up. In recent decades, technological progress has been favoured with the development of a great variety of diagnostic tests. Moreover, a very valuable tool helping to solve this problem has gained strength and is available to everybody - so-called 'evidence-based medicine'. There are three categories in infertility diagnostic tests. The first category includes tests showing a well-established correlation with pregnancy, e.g. semen analysis, tubal patency with hysterosalpingography or laparoscopy, and ovulation detection. The second category includes patients whose results are not consistently related to pregnancy. Here, these tests include sperm penetration assay in the zona-free hamster oocyte, post-coital tests, sperm penetration into cervical mucus, and tests to detect anti-sperm antibodies. The third group includes patients whose tests are not correlated with pregnancy. The relevant tests include endometrial biopsy, the presence of varicocele, and Chlamydia detection tests. Tests for infertility are often expensive. Since these patients are usually anxious and eager and will do almost anything to have a child, care must be taken to avoid exploitation of their hopes with unnecessary procedures. This text now reviews and updates the procedures used to investigate infertility.

The treatment and outcome of cancer patients with thromboses on central venous catheters.

Thromboses are a common complication of central venous catheters in cancer patients. This study was performed to analyze retrospectively the treatment and outcome of all patients with venous thromboses related to central venous catheters at a major cancer center. From 1992 through 1995, 319 oncology patients with central venous catheters underwent radionuclide venography (RNV) at the Dana-Farber Cancer Institute for suspected catheter or venous thrombosis. The treatment and outcome of patients found to have venous thromboses were evaluated. Of the 319 patients, 112 were found to have evidence of venous thrombosis. The median age and platelet counts were not significantly different between the patients with and without thromboses. The most common indication for obtaining RNV was difficulty in aspirating or infusing material through the catheter. Patients who had pain or edema, or both, of the neck or upper extremity were more likely to have a venous thrombosis. Regardless of therapeutic intervention, including anticoagulation with heparin or coumadin, or both; line removal or replacement; or a combination thereof, no patients had a major adverse outcome such as pulmonary embolism, compromise of limb, or death. Only 4 patients did not have resolution of their presenting symptoms, all of whom were treated with line replacement. The overall survival of patients with and without thromboses was not significantly different. Either anticoagulation or removal of the central venous catheter (or both) appears to be adequate treatment for catheter-related thrombosis. A prospective trial to evaluate these approaches may be worthwhile so that the use of unnecessary procedures may be avoided in this patient population.

[Quality assessment using AGIR: results and experience].

PURPOSE: To evaluate whether a new software from the working group for interventional radiology (AGIR) is an appropriate tool for quality assurance in interventional radiology, and presentation of results acquired within the quality improvement process in 1999. PATIENTS AND METHODS: AGIR-defined parameters such as patient data, risk profile, given interventions as well as complications were registered by a recently developed software. Based on monthly data analyses, possible complications were identified and discussed in morbidity and mortality conferences. RESULTS: 1014 interventions were performed in our institution in 1999. According to criteria established by AGIR, the complication rate was 2.7%. In addition and according to SCVIR criteria, complications were distinguished quantitatively in five classes and semiquantitatively in minor and major groups. The result was a minor complication rate of 1.8%, and a major rate of 0.9%. There were no cases of death associated with the intervention. Further strategies were developed in order to reduce the complication rate. CONCLUSION: Extensive quality assurance methods can be integrated in daily routine work. These methods lead to an intensive transparency of treatment results, and allow the implementation of continuous quality improvements. The development of the software is a first step in establishing a nation-wide quality assurance system. Nevertheless, modification and additional definition of the AGIR predefined parameters are required, for example, to avoid unnecessary procedures.

[Chronic intestinal pseudo-obstruction: pathogenesis, diagnosis and therapy].

Chronic intestinal pseudo-obstruction (CIPO) is a rare disease in which a severe intestinal motility disorder impairs transit of chyme so that patients suffer from symptoms of a mechanical ileus without mechanical obstruction. CIPO may be a primary or secondary disorder due to muscular, neurologic, metabolic or endocrine disorders, but may also occur postinfectiously, postoperatively, following abdominal radiation or be caused by drugs or noxae. In severe cases, the typical history of (repeated) symptoms of mechanical obstruction leading to unsuccessful laparotomies will give key clues for diagnosis. If CIPO is suspected, mechanical obstruction must be searched for carefully by radiologic and endoscopic examinations. Histologic diagnosis usually demands full thickness biopsies of the intestinal wall. Small intestinal manometry allows diagnosis of CIPO even during oligosymptomatic intervals as well as differentiation between neuropathic and myopathic forms of the disease. The main therapeutic goals consist in: 1. Maintenance of an adequate nutritional state by oral and/or enteral nutrition; in severe cases home-parenteral nutrition may be required and particularly in children intestinal transplantation may be the ultima ratio. 2. Reconstitution of intestinal propulsion by prokinetic drugs. 3. Therapy of complications such as bacterial overgrowth and severe pain by antibiotics and specific surgical procedures. Unnecessary laparotomies should be strictly avoided because they may lead to adhesions and markedly complicate the clinical course.

Noninvasive imaging of insulinomas and gastrinomas with endoscopic ultrasonography and somatostatin receptor scintigraphy.

BACKGROUND: Classic morphological techniques are of limited value for imaging endocrine duodenopancreatic tumors, and invasive procedures such as intraarterial stimulation are often used. Two noninvasive procedures, endoscopic ultrasonography (EUS) and somatostatin receptor scintigraphy (SRS), were recently described with promising results. METHODS: In this study we correlated the results of preoperative EUS (n = 34) and SRS (n = 30) with operative findings in patients with histologically proven insulinoma (n = 20) or gastrinoma (n = 21). RESULTS: The sensitivity and positive predictive value (PPV) of EUS were respectively 77% and 94% for pancreatic tumors (insulinomas and gastrinomas), 40% and 100% for duodenal gastrinomas, and 58% and 78% for metastatic lymph nodes. The sensitivity and PPV of SRS for insulinoma were 60% and 100%, respectively. In patients with gastrinoma, the sensitivity and PPV of SRS were respectively 25% and 100% for pancreatic gastrinomas, 72% and 100% for duodenal gastrinomas or periduodenal metastatic lymph nodes, and 67% and 80% for liver metastasis. In patients with multiple endocrine neoplasia, neither one of the two techniques detected all tumors. Overall sensitivity of combined EUS and SRS was 89% for insulinoma (n = 9) and 93% for gastrinoma (n = 14). CONCLUSIONS: EUS and SRS for gastrinomas and insulinomas should be considered as the initial preoperative imaging procedures and may render invasive procedures unnecessary for most patients.

The relationship between pre-hospital and emergency department Glasgow coma scale scores.

INTRODUCTION: Pre-hospital GCS scores are used to make critical patient care decisions and to fill in gaps in hospital-based TBI surveillance, but they may not be accurate. OBJECTIVE: To determine the relationship between pre-hospital (EMS-GCS) and emergency physician GCS scores (ED-GCS). METHODS: Prospective observational study of 60 TBI patients with a field GCS of 8-13 and age > 18. ED-GCS, EMS-GCS, time of GCS and vitals signs were recorded. ANALYSIS: Simple and multiple linear regression. RESULTS: The median EMS-GCS was 13 and that for ED-GCS was 15. There was a significant linear relationship between ED-GCS and EMS-GCS (r = 0.45, p = 0.003). There was improvement in the prediction of ED-GCS when alcohol/drug use and age (but not time) were added to EMS-GCS. CONCLUSION: EMS-GCS is usually two points lower than ED-GCS, but the correlation between them is strong and independent of the time between score determinations. These results could prevent unnecessary procedures based on the EMS-GCS and improve the accuracy of TBI surveillance.

Effects of the early diagnosis of amyotrophic lateral sclerosis on the patient: advantages.

Advantages of early diagnoses in amyotrophic lateral sclerosis include validation of symptoms, avoidance of unnecessary procedures, enhanced preparation for disability and medical education. Most importantly, earlier in the course of the disease--while there is a greater motor neuron pool survival--diagnosis would enable earlier treatment intervention.

Congenital malaria in the United States: report of a case and review.

Congenital malaria, an uncommon disease in the United States, may result in serious morbidity when not promptly diagnosed. All cases of congenital malaria known to have been seen in the United States since 1950 are reviewed and the most recent case is presented to illustrate the salient features of this disease. Congenital malaria may remain undiagnosed for a prolonged period unless considered in the differential diagnosis of fever, anemia, and splenomegaly in an infant less than 4 months of age whose mother's travel history is unknown. This circumstance often results in the performance of unnecessary procedures, ineffective treatments, and potentially significant morbidity and expense.

Absence of heat treatment of serum for culture medium supplementation does not adversely affect the outcome of in-vitro fertilization.

This study was carried out to determine if not heat-treating serum prior to use for medium supplementation adversely affected in-vitro fertilization (IVF) of human oocytes. Morphologically mature human oocytes derived from 135 patients undergoing IVF treatment were studied. A total of 504 oocytes were incubated, inseminated and the resulting pronuclear oocytes cultured further in Earle's balanced salt solution (EBSS) supplemented with 10% non-heat-treated serum. Comparisons of fertilization rate and embryonic development were made between these and 687 control oocytes derived from the same patients but incubated, inseminated and resulting pronuclear oocytes cultured further in EBSS supplemented with 10% heat-treated serum. The fertilization rate of 74.4% (375/504) of oocytes handled in serum-supplemented medium that had not been heat-treated was significantly better than the rate of 67.7% (465/687) for controls (P < 0.0125). The proportion of pronucleate oocytes that cleaved was also significantly better in the non-heat-treated serum group: 270/300 (90%) versus 307/375 (81.8%) (P < 0.0025). There was no significant difference in the proportion of embryos with four or more cells at the time of embryo transfer. The results show that the absence of heat treatment of serum used to supplement culture medium has no adverse effect on the fertilization rate and short-term embryo development in vitro; hence we suggest that serum heat treatment is an unnecessary procedure and could be abandoned.

Magnetic resonance imaging of sports injuries of the spine.

Spinal injuries are relatively frequent events in professional athletes. Greater popularity of recreational athletic activities has increased the occurrence of sports-related spinal injuries in the general population. The demand of high-intensity sports places a constant load on the vertebral column. Several studies have demonstrated higher prevalence of spinal abnormalities in athletes than nonathletes. Direct correlation of the number and extent of injuries with the length in years of sports activity has been established. Diagnostic imaging, particularly magnetic resonance imaging (MRI), plays a crucial role in evaluating and detecting sports-related spinal injuries. Subtle bone marrow, soft-tissue, and spinal cord abnormalities, which may not be apparent on other imaging modalities, can be readily detected on MRI. Early detection often leads to prompt accurate diagnosis and expeditious management, in many cases avoiding unnecessary procedures. This article reviews the technical aspects of MRI for evaluation of the spine and the role of MRI in the assessment of sports-related spinal injuries.

Gallbladder and pancreatic involvement in hepatitis A.

Gallbladder (GB) abnormalities are rarely reported in children, but involvement of the GB has been demonstrated in various inflammatory disorders. Thirty-nine children hospitalized with hepatitis A virus infection were evaluated by ultrasound. Pseudosurgical gallbladder wall of 10 mm or more with striation was found in 10. Pathological echographic findings were found in the pancreas of three patients, one with frank pancreatitis. Ascitic fluid was noted in eight. Pediatricians and pediatric surgeons alike should be familiar with this gallbladder and pancreatic involvement, which might avoid unnecessary procedures or surgery.

The length of hospital stay after an unnecessary laparotomy for trauma: a prospective study.

OBJECTIVE: To record length of hospital stay (LOS) for patients for whom unnecessary laparotomies for trauma (no repair, no drain) were performed. The influence of complications and associated injuries on the LOS would be studied. DESIGN: Prospective case series. MATERIALS AND METHODS: Data were recorded concurrently for consecutive patients on whom unnecessary laparotomies for trauma were performed at a trauma center. MEASUREMENTS AND MAIN RESULTS: The main and secondary outcome measures were LOS and the influence of complications or associated injuries on the LOS, respectively. From 1988 until 1991, unnecessary laparotomies for trauma were performed on 254 patients. The overall mean LOS was 8.1 days (median, 6 days; range, 1-80 days), whereas the overall mean LOS for 81 patients who had no associated injuries and on whom completely negative laparotomies were performed was 4.7 days (median, 5 days; range, 2-8 days). Complications occurred in 41.3% of the patients and increased the mean LOS from 5 days (no complication) to 9 days (complication) (p = 0.0002). Associated injuries occurred in 43.7% of the patients and increased the mean LOS from 5.3 days (no associated injury) to 11.7 days (associated injury) (p = 0.0001). CONCLUSIONS: Unnecessary laparotomies for trauma resulted in a significant LOS. The presence of a complication or an associated injury significantly prolonged the LOS. Current efforts to reduce the incidence of these unnecessary procedures and minimize the occurrence of complications are worthwhile.

An economic study of cost savings on a care-by-parent ward.

Alternatives to inpatient care that improve quality of care and save money are desirable during periods of restraint on hospital budgets. One such alternative is the care-by-parent unit (CBPU) in which a parent's stay on the ward can reduce costs by resuming nursing tasks, limiting unnecessary procedures, and encouraging early discharge. This study measured costs per case treated in the CBPU compared with the costs for similar patients treated in the inpatient nursing unit (NU). Average costs per episode were lower in the CBPU--33 per cent for general pediatrics, 13.5 per cent for tonsils and adenoids and 29 per cent for other surgery. These savings are capable of considerable expansion because more than half of the admissions to NU meet the criteria for admission to CBPU. If CBPU facilities were expanded, however, the savings estimated above would not follow automatically. New CBPU facilities must substitute for NU, not add to total utilization.

Clinical predictors of computed tomographic abnormalities following pediatric traumatic brain injury.

Children commonly seek attention in emergency departments following head injury. Head computed tomography (CT) is often used to decide subsequent disposition. Clinical criteria predicting CT abnormalities would allow effective and timely treatment and minimize unnecessary procedures depleting overburdened medical resources. We prospectively compared presenting clinical features with subsequent emergent head CT in 300 children less than 19 years old over a nine-month period. The disposition of patients following imaging was also recorded. Only suspected abuse was more than 50% positively predictive in children below age two and those above age two. Two signs were more than 67% positively predictive in both age groups: focal motor deficit and pupillary asymmetry. Patients with abnormal CTs were the only children to undergo emergent neurosurgery (30%) and were nearly five times as likely to be intensively monitored. Children with normal CTs were nearly five times as likely to be observed in a routine department or at home. We conclude that no single clinical feature can predict with certainty an abnormality on immediate head CT. However, children suspected of being abused, and those with focal motor deficits or pupillary asymmetry, should be imaged. Finally, emergent CT when judiciously ordered likely reduces unforeseen morbidity and minimizes costly intensive care observation.

Azygos continuation of the inferior vena cava masquerading as neoplasm.

The two cases we have reported demonstrate that dramatic enlargement of the azygos vein may occur in patients with azygos continuation of the inferior vena cava. Awareness of this phenomenon can prevent unnecessary procedures. The diagnosis should be established by dynamic CT scan.
