Emphysematous gastritis associated with ulcerative esophagitis.

Emphysematous gastritis is a rare form of gastritis characterized by gaseous dissection of the stomach wall usually secondary to invasion by gas forming organisms, corrosive ingestion, trauma, or gastric infarction. We report a unique case of emphysematous gastritis secondary to ulcerative esophagitis without an underlying history of trauma, ischemia, or ingestion of corrosive agents. The patient responded well to conservative management. Emphysematous gastritis is a deadly infectious disease. Early recognition and management are crucial as there is no specific approach to treatment despite advances in medical science.

Reversible posterior leucoencephalopathy syndrome associated with anticancer drugs.

BACKGROUND: Reversible posterior leucoencephalopathy syndrome (RPLS) is an underappreciated clinical-radiologic syndrome characterized by reversible cortical dysfunction preferentially involving the occipital lobes in conjunction with imaging findings of reversible subcortical oedema. As RPLS is being increasingly identified within the oncology population in association with cytotoxic chemotherapy and targeted agents, a review of the published work in English was carried out. METHODS: A MEDLINE search of the published work in English was conducted to identify cases of RPLS in patients more than 16 years of age who were treated with anticancer drugs for documented malignancy. Only cases with adequate documentation regarding demographic and treatment data, cerebral magnetic resonance imaging and outcome were selected. RESULTS: We identified 24 patients with RPLS associated with a variety of anticancer drugs, most commonly complicating polychemotherapy and/or bevacizumab-containing regimens. There was a female predominance: 18 females and 6 males (P= 0.023). Women were of premenopausal age and were younger than males: 49.3 +/- 16.4 years versus 60.7 +/- 6.4 years (P= 0.09). Most patients presented with acute headache (67%), seizures (63%), confusion (54%) or cortical blindness (46%) with mean systolic and diastolic blood pressure of 168 +/- 15 and 98 +/- 15 mm Hg, respectively. Findings on magnetic resonance imaging showed hyperintense lesions on T(2)-weighted images in all patients, which involved the occipital lobes in 75% of patients; all patients experienced clinical and radiologic resolution within days to weeks. No deaths were directly attributed to RPLS. CONCLUSIONS: Combination and single-agent chemotherapy as well as novel anticancer drugs are associated with RPLS. We found RPLS to be overrepresented in premenopausal woman; the prevalence in this subgroup may be related to an anticancer drug-oestrogen interaction inducing altered cerebral vasoreactivity and endothelial dysfunction.

Development and transferability of a cost-effective laparoscopic camera navigation simulator.

BACKGROUND: Laparoscopic camera navigation (LCN) is vital for the successful performance of laparoscopic operations, yet little time is spent on training. This study aimed to develop an inexpensive LCN simulator, to design a structured curriculum, and to determine the transferability of skills acquired. METHODS: In this study, 0 degrees and 30 degrees LCN simulators were developed for use on a videotrainer platform. Transferability was tested by enrolling 20 medical students in an institutional review board-approved, randomized, controlled, blinded protocol. Subjects viewed a video tutorial and were pretested in LCN on a porcine Nissen model. Procedures were videotaped and the LCN performance was scored by a blinded rater according to the number of standardized verbal cues required and the percentage of time an optimal surgical view (%OSV) was obtained. Procedure time also was recorded. Subjects were stratified and randomized. The trained group practiced on the LCN simulator until competency was demonstrated. The control group received no training. Both groups were posttested on the porcine Nissen model. RESULTS: The constructed simulators required 35 man hours for development, cost $25 per board for materials, and proved to be durable. The trained group demonstrated significant improvement in verbal cues (p = 0.001), %OSV (p < 0.001), and procedure time (p = 0.001), whereas the control group showed improvement only in verbal cues (p < 0.02). At posttesting, the training group demonstrated significantly better scores for verbal cues (2.1 vs 8.0; p = 0.02) and %OSV (64% vs 45% p = 0.01) than the control group. CONCLUSION: These data suggest that the LCN simulator is cost effective and provides trainees with skills that translate to the operating room.

Length of esophageal cancer and degree of luminal stenosis during upper endoscopy predict T stage by endoscopic ultrasound.

BACKGROUND AND STUDY AIMS: Endoscopic ultrasonography (EUS) is considered to be the most accurate modality for T staging of esophageal cancer. This study attempted to determine whether endoscopic features such as the length and degree of luminal stenosis in esophageal cancer can predict the T stage on EUS. PATIENTS AND METHODS: Thirty-five patients with newly diagnosed esophageal adenocarcinoma or squamous-cell carcinoma undergoing EUS prior to initiation of any treatment were included in the study. The length of the tumor was assessed prospectively during esophagogastroduodenoscopy (EGD) before EUS in 22 patients. Radial EUS was then performed in these patients. The other 13 patients had sufficient luminal stenosis to prevent complete advancement of the echo endoscope through the tumor. In these 13 patients, the length of the esophageal cancer was not examined, but the T and N stage up to the level of maximum advancement of the echo endoscope through the tumor were noted. RESULTS: All 13 patients with luminal stenosis had at least a T3 (n = 12) or T4 (n = 1) lesion up to the level of maximum advancement of the echo endoscope. Among the 22 patients in whom the length of the esophageal cancer was measured, the mean length in the 13 patients with a T1 or T2 lesion on EUS was 2.6 cm. The mean length in the nine patients with T3 esophageal cancer was 7.1 cm. The difference in the mean length of T1 or T2 lesions (2.6 cm) was significantly different ( P < 0.001) from the mean length of T3 lesions (7.1 cm). Using a clinical diagnostic testing approach, when > or = 5 cm length was used as a criteria for diagnosing T3 lesions, the sensitivity was 89 %, specificity 92 %, positive predictive value 89 %, and negative predictive value 92 %. There was also a suggestion of increased chances of lymph-node metastases with increasing length of esophageal cancer. CONCLUSIONS: In esophageal carcinoma, endoscopic features such as the length of the cancer and the degree of luminal stenosis correlate with T staging on EUS. Esophageal cancers that are > or = 5 cm in length, or are sufficiently stenotic to prevent passage of an endoscope, are much more likely to be T3 or higher-stage lesions, while those that are < 5 cm in length have a greater chance (92 %) of being T1 or T2.

Social implications of blepharoptosis and dermatochalasis.

PURPOSE: To investigate the social implications of blepharoptosis and dermatochalasis. METHODS: Two hundred ten individuals rated whole-face photographs of a series of patients based on 11 different personal characteristics: intelligence, threat, friendliness, health, trustworthiness, hard work, mental illness, financial success, attractiveness, alcoholism, and happiness. Preoperative and postoperative photographs of both male and female patients with bilateral blepharoptosis and/or dematochalasis were used. The paired t test was used to compare preoperative versus postoperative ratings on the 11 characteristics. RESULTS: The preoperative photographs were rated more negatively than were the postoperative photographs (p < 0.01) on all 11 characteristics for both male and female patients by the 210 study subjects. CONCLUSIONS: Members of our society view individuals with blepharoptosis and dermatochalasis negatively. These social attitudes may lead to unjust bias toward affected patients, and surgical correction probably provides benefits beyond improved visual function.

Acute care of patients aged 95 to 99 years: experience in a community teaching hospital.

BACKGROUND: People older than 90 years represent an increasing segment of the US population, but little information exists on their hospitalization for acute illness. METHODS: We retrospectively analyzed the clinical characteristics of patients aged 95 through 99 years admitted during 1 year to a large teaching hospital. RESULTS: Of 43 patients admitted at least once, 14 were admitted twice, 6 were admitted three times, and 1 was admitted four times; 35 (81%) were women, and 8 (19%) were men. Patients admitted more than once took a mean of 6.8 +/- 3.3 drugs compared with 4.4 +/- 2.6 drugs for patients admitted only once. Routine laboratory values were typically normal or mildly abnormal. Mean hospitalization was 5.6 +/- 3.5 days. Only 2 patients (5%) died. All 11 patients with a recent fall were discharged to a long-term nursing facility, compared with only 18 of 30 patients without a recent fall. CONCLUSIONS: Patients aged 95 through 99 years generally have a favorable prognosis when hospitalized for an acute medical condition. However, patients with a recent fall are more likely to require placement in a long-term nursing facility, and patients taking six or more drugs on admission are more likely to be rehospitalized within 12 months.

Spectrum of upper-extremity deep venous thrombosis in a community teaching hospital.

OBJECTIVE: The goal of this study was to characterize the spectrum of upper-extremity deep venous thrombosis in a community teaching hospital. DESIGN AND SETTING: A retrospective analysis was used at a large urban teaching hospital. MATERIAL AND METHODS: We reviewed the records of 90 patients with ultrasound-documented thrombosis of the internal jugular, subclavian, axillary, or brachial veins to determine clinical characteristics, risk factors, and outcome. RESULTS: The most common underlying conditions associated with upper-extremity deep venous thrombosis were the presence of a central venous catheter in 65 patients (72%), infection in 25 (28%), extrathoracic malignancy in 20 (22%), thoracic malignancy in 19 (21%), renal failure in 19 (21%), and a prior lower-extremity deep venous thrombosis in 16 (18%). Pain was noted in 31 (34%) patients, and 76 patients (84%) had edema of the involved extremity. The left subclavian vein was involved in 44 patients (49%), and 35 patients (39%) had a central venous catheter in the left subclavian vein. When a central venous catheter was present, the deep venous thrombosis was usually ipsilateral (P <.001). Heparin and warfarin were administered to 65 (72%) and 53 (59%) of the patients, respectively. Eleven patients (12%) died. Of these patients, 8 (73%) had an underlying infection, whereas only 22% of survivors had an infection (P =.0012). CONCLUSION: Upper-extremity deep venous thrombosis typically occurs in patients with a systemic illness in the presence of a central venous catheter. The left subclavian vein is frequently involved because this is a common site for placement of a central venous catheter. Pain is uncommon, but edema of the involved extremity is noted in the majority of patients. The mortality rate of patients in this study with an upper-extremity deep venous thrombosis was 12%; most patients who died had a central venous catheter and an underlying infection.

Stromal eosinophilia in colonic epithelial neoplasms.

OBJECTIVE: The purpose of this retrospective study was to determine the frequency and intensity of eosinophilic infiltration (or tissue eosinophilia) in the stroma of colonic adenomas, hyperplastic polyps, and colorectal adenocarcinomas. Eosinophilic infiltration in various malignancies has been reported but has not been evaluated in benign colorectal adenomas and hyperplastic polyps. METHODS: We analyzed 488 colonic neoplasms: 176 tubular adenomas, 55 tubulovillous adenomas, 82 villous adenomas, 15 early carcinomas in polyps, 95 invasive adenocarcinomas, and 65 hyperplastic polyps for the presence of eosinophilic infiltration. The eosinophilic infiltration was graded as negative (< or =5%), mild to moderate (>5-40%), or marked (>40%), depending on the percentage of eosinophils relative to total inflammatory cells in the stroma. RESULTS: Mild to moderate eosinophilia was noted in 75% of all adenomas. The transitional zone in all cases of invasive adenocarcinoma (zone between normal tissue and adenocarcinoma) revealed a high percentage of tissue eosinophilia. There was a striking absence of TE in the stroma of invasive adenocarcinomas. Only 5% of hyperplastic polyps had any eosinophilic infiltration. CONCLUSIONS: These data suggest that, in the spectrum of colonic neoplasms, stromal eosinophilia is most prominent in adenomas and seems to decrease with progression through the adenoma-carcinoma sequence. The ramifications of this study may alter management plans and provide some prognostic information for clinical evaluation.

Stenotrophomonas maltophilia infection and colonization in the intensive care units of two community hospitals: A study of 143 patients.

STUDY OBJECTIVE: To study the epidemiology of Stenotrophomonas maltophilia infections in the intensive care units (ICUs) of community general hospitals. DESIGN: Retrospective chart review of 143 patients with cultures positive for S. maltophilia over a 2-year period. SETTING: Intensive care units of 2 community general hospitals. RESULTS: Patients with S. maltophilia infection or colonization were elderly (mean age 62.4 years), intubated for a mean of 11.8 days, and had a mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score of 16.6. A tracheostomy was present in 22.4%, and underlying chronic respiratory disease and malignancy were found in 25.9% and 15.4%, respectively. Only 2 patients (1.4%) were neutropenic. Most isolates (89.5%) were from the respiratory tract and were part of a polymicrobial culture in 52. 5% of patients. Only a slightly higher APACHE II score (mean = 18.0, SD 7.8 vs mean = 15.6, SD 6.2, P = 0.052) differentiated patients with infection from those with colonization. All but 2 patients were exposed to antibiotics before their positive culture. Crude mortality rate was 41.3% overall and was significantly higher in those with an APACHE II score of 15 or more (48.8% vs 30.5%, P = 0. 028). CONCLUSION: S. maltophilia is emerging as an important cause of nosocomial infection, especially pneumonia, in ICUs of community general hospitals. Patients tend to be elderly, intubated for a mean of about 12 days, have high APACHE II scores, and frequently have a tracheostomy or underlying chronic respiratory disease. In contrast to earlier reports, neutropenia and underlying malignancy are uncommon in our ICU population. We found prior antibiotic exposure was almost universal and similar to previous reports, but use of imipenem was much less common in our community hospital patients. Patients with a high APACHE II score should be considered infected rather than colonized, but differentiation of infection from colonization remains problematic. Isolation of S. maltophilia from a patient carries a crude mortality rate of 41.3%, and patients with an APACHE II score of 15 or more have a significantly higher mortality rate than those with lesser scores, approaching 50%. Trimethoprim-sulfamethoxazole (TMP-SMX) remains the drug of choice for infections caused by S. maltophilia.

Observation of thoracic duct morphology in portal hypertension by endoscopic ultrasound.

BACKGROUND: Thoracic duct dilation has been demonstrated in portal hypertension and hepatic cirrhosis by lymphangiography and laparotomy and at autopsy. It is thought to be secondary to increased hepatic lymph flow and has been described in the absence of ascites or esophageal varices. The aim of the present study was to observe thoracic duct morphology by endoscopic ultrasound in various subsets of patients with portal hypertension and hepatic cirrhosis and also to validate existing radiologic/surgical data. METHODS: The thoracic duct of 33 patients with cirrhosis and portal hypertension was studied by endoscopic ultrasound. Patients were divided into four groups: 1, patients with ascites and esophageal varices; 2, esophageal varices without ascites; 3, without esophageal varices or ascites; 4, extrahepatic portal hypertension due to pancreatic malignancy. The thoracic duct diameter was also measured in 14 control subjects (group 5). RESULTS: When the thoracic duct diameter for the five groups was compared with analysis of variance, significance was p < 0.0001; by pairwise comparison, group 1 differed from the other four groups (p < 0.05). Thoracic duct dilation (5.61 mm) was seen in group 1 patients, whereas no dilation was present in groups 2 through 4. Additionally, thoracic duct diameter in 33 portal hypertensive and/or cirrhotic patients was significantly different from that in the 14 control subjects (p = 0. 003). CONCLUSION: The thoracic duct can be reliably identified by EUS in patients with hepatic cirrhosis and portal hypertension. Dilation of the duct is seen only in patients with hepatic cirrhosis, ascites, and esophageal varices. No thoracic duct dilation is present in extrahepatic portal hypertension. Contrary to existing radiologic/surgical data, thoracic duct dilation is not seen in all patients with hepatic cirrhosis and portal hypertension signifying advanced disease. A dilated thoracic duct by endoscopic ultrasound should be considered yet another sign of portal hypertension.

Constitution and solution conformation of the antibiotic mersacidin determined by NMR and molecular dynamics.

The solution structure of the tetracyclic lantibiotic mersacidin in methanol (CD3OH) has been determined by NMR followed by distance bound driven dynamics and subsequent restrained molecular dynamics simulations combined with an iterative relaxation matrix approach and alternatively by a simulated annealing protocol. The molecular dynamics simulations were performed with the AMBER program system and with the INSIGHT program package. The distance bound driven dynamics calculation was conducted using a modified version of the DISGEO II program. The interproton distance restraints were derived from jump symmetrized rotating-frame Overhauser enhancement and exchange (JS-ROESY) spectra, which yield optimum sensitivity for medium-sized molecules like mersacidin. The connectivities via the sulfide bridges were unambiguously confirmed by heteronuclear NMR techniques (heteronuclear single quantum coherence and heteronuclear multiple bond correlation methods). Due to the tetracyclic structure, mersacidin exhibits a rather rigid globular shape, which neither belongs to the duramycin nor to the nisin structure type lantibiotics. The resulting structures for the simulated annealing protocol of restrained and subsequent free molecular dynamics were compared and found to be very similar.

Is in vivo measurement of size of polyps during colonoscopy accurate?

BACKGROUND: Accurate measurement of polyp size during colonoscopy is important because of the direct correlation of size with colon cancer. Major studies of colorectal neoplasms have measured polyp size differently. It is also well documented that endoscopists underestimate polyp size frequently. The goal of this prospective study was to determine which one of the five methods of estimating polyp size during colonoscopy is most accurate. METHODS: One hundred colon polyps were measured by means of visual estimation, open biopsy forceps methods, linear probe, a ruler immediately after excision, and after fixation in formalin. The size of the polyps measured outside the body immediately after excision was considered the "gold standard" against which all measurements were compared. RESULTS: Forty-seven polyps were 5 mm or less in diameter, 33 polyps were 5.01 mm to 10 mm, and 20 polyps were more than 10 mm in size. For all polyps the mean difference versus the actual size of the polyps was 3.4% for linear probe, 6.4% for visual estimation, and 12.3% for the forceps. CONCLUSION: Measurement of polyp size by linear probe agreed best with the actual polyp size, followed closely by visual estimation. The open biopsy forceps method was the least accurate.

A prospective controlled evaluation of endoscopic detection of angiodysplasia and its association with aortic valve disease.

BACKGROUND: In view of controversy about the association of aortic stenosis and angiodysplasia of the gut, we performed a prospective, controlled study to evaluate the relationship between aortic valve disease and gastrointestinal angiodysplasia. METHODS: Forty patients who had endoscopy for clinical indications such as gastrointestinal bleeding, anemia, polyps, colon cancer, and dyspepsia, and who were found to have angiodysplasia of the gastrointestinal tract, underwent two-dimensional and Doppler echocardiography. Thirty-seven controls matched for age, sex, indication, and nature of endoscopic examination, but without angiodysplasia, underwent similar echocardiographic examination. RESULTS: None of the patients in either group had aortic stenosis. The prevalence of aortic sclerosis, aortic insufficiency, and low left ventricular ejection fraction was similar in patients with and without angiodysplasia. CONCLUSIONS: This study does not support the role of aortic valve disease as the cause of angiodysplasia of the gastrointestinal tract. A subgroup of patients with angiodysplasia with aortic sclerosis, with or without other valvular disease (but none with aortic stenosis), had increased prevalence of gastrointestinal bleeding when compared with controls. When aortic valve disease or decreased left ventricular ejection fraction were analyzed as independent predictors, none of them in and of itself appeared to be a factor in bleeding from these gastrointestinal lesions.

A comparative study of eight fecal occult blood tests and HemoQuant in patients in whom colonoscopy is indicated.

BACKGROUND AND OBJECTIVE: Some studies suggest that immunochemical fecal occult blood tests (FOBTs) and HemoQuant are more efficient at detecting fecal occult blood than the commonly employed Hemoccult II (guaiac) test. We undertook this study to determine whether an immunochemical test either alone or in combination with a guaiac test gives efficiency superior to the Hemoccult II test in predicting significant gastrointestinal tract disease. DESIGN: Criterion standard, prospective, blinded. SETTING: Referral population of ambulatory patients at an institutional and a private hospital. PATIENTS: Eight-one patients referred to a gastroenterologist and in whom colonoscopy was indicated. INTERVENTIONS: While on a restricted diet, patients made preparations for FOBTs from three consecutive bowel movements. Patients then underwent colonoscopy. Polyps larger than 1 cm in size, carcinoma of the colon, peptic ulcers, gastric erosions, and angiodysplasia were considered to be likely causes of occult gastrointestinal tract bleeding. MAIN OUTCOME MEASURES: Using colonoscopy results as the reference standard, sensitivity, specificity, and positive and negative predictive values for each of eight tests or pair of tests were compared with those of Hemoccult II. RESULTS: Of 81 patients, 10 had significant lower gastrointestinal tract lesions and six had significant upper gastrointestinal tract lesions. Hemoccult SENSA, Heme-Select, and FECA-EIA were shown to be more sensitive than Hemoccult II but slightly less specific. Paired tests showed less efficiency than Hemoccult II alone. CONCLUSIONS: We did not find an ideal test or pair of tests; however, Hemoccult SENSA exhibited higher sensitivity than Hemoccult II and many other tests. The sensitivity, specificity, and positive predictive values of many of the FOBTs were believed to be low. We recommend that physicians consider FOBTs only as adjuncts to history and physical examination findings in deciding how to proceed in diagnosing gastrointestinal tract disease.

Survival factors in rhino-orbital-cerebral mucormycosis.

Mucormycosis is a highly aggressive fungal infection affecting diabetic, immunocompromised, and, occasionally, healthy patients. This infection is associated with significant mortality. We have reviewed 208 cases in the literature since 1970, 139 of which were presented in sufficient detail to assess prognostic factors, and added data from six of our patients. The histories of these 145 patients were analyzed for the following variables: 1) underlying conditions associated with mucormycotic infections; 2) incidence of ocular and orbital signs and symptoms; 3) incidence of nonocular signs and symptoms; 4) interval from symptom onset to treatment; and 5) the pattern of sinus involvement seen on imaging studies and noted at the time of surgery. Factors related to a lower survival rate include: 1) delayed diagnosis and treatment; 2) hemiparesis or hemiplegia; 3) bilateral sinus involvement; 4) leukemia; 5) renal disease; and 6) treatment with deferoxamine. The association of facial necrosis with a poor prognosis fell just short of statistical significance, but appears clinically important. This is the first review that documents the heretofore intuitive claim that early diagnosis is necessary to cure this disease. Standard treatment with amphotericin B and aggressive surgery are reviewed and adjunctive therapeutic modalities are discussed, including local amphotericin B irrigation, hyperbaric oxygen, and optimizing the immunosuppressive regimen in transplant patients. Hyperbaric oxygen was found to have a favorable effect on prognosis. In addition, possible treatment options for patients with declining renal function are reviewed.

Comparing clerkship sites in a community-based medical school by evaluating students' undergraduate and postgraduate performances.

BACKGROUND: Studies have generally found clinical training sites within the same clerkship to be comparable regarding students' performances--by using undergraduate measures in individual clerkships at medical schools with university hospitals. The present study examined performance comparability among sites within two clerkships in a community-based medical school and used both undergraduate and postgraduate measures. METHOD: The participants were the 349 graduates from the classes of 1988-1991 at Wright State University School of Medicine who took an internal medicine clerkship (332 of the graduates, in five principal combinations of sites) and a general surgery clerkship (349 at six sites). The undergraduate measures were final percent scores for the clerkships and subtest and total scores on the National Board of Medical Examiners (NBME) Part II examination. The postgraduate measures were supervisors' ratings from the first year of residency (210 graduates) and total score on the NBME Part III (212). Univariate analysis of variance and Tukey's multiple-range test were used for the comparisons. RESULTS: The only statistically significant difference among sites was for the medicine clerkship and involved only one undergraduate measure, the clerkship score (and the differences were slight, less than four percentage points). CONCLUSION: Virtually no differences in the students' performances on the undergraduate and postgraduate measures were found among sites for the two clerkships.

Potential influences of residencies' health risk policies on their rankings by Ohio applicants.

Residents' health risks constitute an area of increasing concern for hospitals and residencies. This study examined the importance of health risk policies in the context of students' selection of residencies. In 1991, all 836 fourth-year students in six Ohio medical schools were surveyed about their attitudes regarding residencies' policies on drug screening, HIV (human immunodeficiency virus) testing, and smoke-free workplaces. Of 763 surveys able to be delivered, 341 (45%) were returned. Substantial subsets of the students indicated that they would rank lower or not at all a program that required pre-residency drug screening (22%) or HIV testing (31%). Conversely, almost half the students (48%) responded that they would rank a program higher whose institution has a smoke-free policy. A discussion of potential factors affecting these findings is presented, with recommendations for hospitals, residencies, and residency applicants.

Cervical cancer: women aged 35 and younger compared to women aged 36 and older.

One hundred fifty-three patients with invasive cervical cancer were evaluated and treated at one of the two teaching hospitals of the Intergrated Ob-Gyn Residency Program of Wright State University, Dayton, Ohio, from 1 July 1983 to 30 June 1989. Sixteen patients with recurrent cervical cancer who initially had received their treatment elsewhere were excluded. Forty-one of the 137 newly diagnosed patients with cervical cancer were aged 35 years or less. This review was undertaken because of frequent reports of the increasing incidence of cervical cancer in women aged 35 and under. Some reports also reveal a worse prognosis for the younger age group. This investigation provided the opportunity to evaluate cervical cancer patients aged 35 and under and compare the results to the evaluations of women aged 36 and over. Evaluation of age, stage, presenting symptoms, number of positive lymph nodes, pap smear history, pregnancy within 1 year of diagnosis, treatment, and survival was carried out in patients aged 35 years and less and compared to their older counterparts aged 36 and over with cervical cancer.

Enterobacter bacteremia in the community hospital.

BACKGROUND: The purpose of this study was to examine the epidemiological and clinical characteristics of Enterobacter bacteremia in the community hospital, where nosocomial infections are not commonly studied. METHODS: The blood culture records of five community hospitals in the Dayton, Ohio, area were reviewed to find cases of Enterobacter bacteremia. The respective hospital charts were then reviewed. RESULTS: Seventy-five episodes of Enterobacter bacteremia were reviewed. Eighty percent (60) of the organisms were nosocomially acquired, and 20% (15) were community acquired. The median age of the patients was 64 years. In 39% (29) of the episodes, fever was not the primary manifestation. The mortality rate was 29% (22). In 30% of the cases, the portal of entry for the bacteremia was unknown. The most common known portals of entry were genitourinary, gastrointestinal or biliary, and peritoneal. The most common underlying disorders were malignancy, postoperative states, and diabetes mellitus. In 9% of the cases, no underlying disorder was detected. The organisms showed high sensitivity to chloramphenicol, aminoglycosides, piperacillin sodium, and cefotaxime sodium. High degrees of resistance were shown to ampicillin, first-generation cephalosporins, and cefoxitin. Eighty-four percent (46) of the patients treated appropriately survived, and 55% (11) of the patients treated inappropriately died. CONCLUSIONS: Enterobacter bacteremia is most commonly nosocomially acquired and appears to be a problem in the community hospital. Appropriate therapy improves rates of patient survival.
