Retrocecal Appendix Location and Perforation at Presentation

Retrocecal appendicitis has been theorized to follow a more insidious course than other anatomic variants. To determine the influence of retrocecal anatomy on clinical course of appendicitis, 200 adult patients treated at a major university medical center with the diagnosis of appendicitis from 2001 to 2004 were retrospectively studied. Computed tomography (CT) scans of adult patients with an ultimate diagnosis of appendicitis were analyzed to determine an association between retrocecal appendix and perforation of the appendix at presentation. A higher perforation rate in the retrocecal group would imply patient delay in presentation from more tolerable symptoms. CT scans were examined for retrocecal location and perforation. No significant association was found between retrocecal anatomy and perforation rates at presentation (chi-square = 2.1, P = 0.15, odds ratio = 1.6, 95% confidence interval [0.8–3.0]). However, the risk of perforation was 60 per cent higher in the retrocecal group. By regression analysis, age and the presence of a fecalith on CT scan were predictors of appendix perforation. Appendix location was not. In this study, we found no significant association between retrocecal appendix anatomy and perforation at presentation.

Number Of Patients

Background A cohort of patients having symptoms of sternal nonunion late after sternotomy was studied to find out whether the complaints were related to true sternal nonunion or decreased bone density. Methods A survey was mailed to 2,053 cardiac surgical patients operated in our institution between July 2007 and June 2010. The patients were requested about symptoms referring to sternal instability. A group of symptomatic individuals as well as 1:1 age- and time-matched asymptomatic controls were examined with sternal palpation, ultrasound during standardized sternal pressure provocation, and computed tomography (CT). Results The number of patients replied in the survey was 1,918 (93.4%); 2.3% (44 patients) reported sensation of movement or clicking in sternum during body movements and during coughing. Symptomatic patients living within 200 km to the hospital (21) and their asymptomatic controls (21) were selected for further clinical and imaging studies. Mean period between the initial operation and the examinations was 36 (22–56) months. Sternal palpation pain was significantly associated with reported symptoms suggestive of sternal nonunion (odds ratio [OR] 22.0; 95% confidence interval [CI] 2.5–195); however, none of the patients had clinically unstable sternum or nonunion in the sternal imaging. The symptoms of sternal instability were more frequent in patients whose bone mineralization rate (as measured with T-scores) was higher. Conclusion Symptoms suggestive of sternal nonunion were experienced by 2.3%. However, their symptoms did not correlate with CT scans or provocation ultrasound although palpation pain was evident. Thus the pain is derived from nonmechanical etiologies. Higher bone mineralization rate correlated with abnormal symptoms of sternal wound.

Abstract Background: The leading cause of sudden cardiac death in adults over 40 is ischemic heart disease due to vascular atherosclerosis. In contrast, sudden cardiac death in adults younger than 40 (young adults) may be caused by aortic hypoplasia (AH). To date, few detailed studies of AH exist. This study evaluated AH patients in our hospital for sudden cardiopulmonary arrest in young adults. Methods: We selected young adult patients who transferred to our center with cardiopulmonary arrest status between April 2010 and March 2020. Their cause of death was supposed to be cardiac or unknown. In the chart review, sex, age, rate of computed tomography (CT) being performed, and outcome were described. For patients with CT being performed, we assessed the diameters of the aortic root, ascending, descending and abdominal aorta, and right femoral artery.Results: There were 1268 cardiopulmonary arrest cases during the study period. Thirteen young adults died of intrinsic diseases, such as sudden cardiac death or unknown cause of death. Twelve patients underwent CT scans, and eight (61.5%) had AH.Conclusions: For a decade, 61.5% of young adults who died of intrinsic diseases had AH. Further studies should be conducted to reveal AH’s clinical significance in young adults.

Abstract Objective An intraarticular sacroiliac joint (SIJ) injection cannot always be performed successfully. Based on the patterns of the sacroiliac arthrogram, we explored possible indicators of technically difficult and technically easy injections into the SIJ including demographic features and anatomical features evident on preprocedural imaging. Design Observational study. Methods We evaluated 76 patients with painful SIJ (total 108 joints) diagnosed by SIJ injections. The sacroiliac arthrogram was graded as follows: Grade (G) 0 = the margin of the joint was partially outlined; G1 = the margin was completely outlined; G2 = intraarticular space was substantially outlined; and G3 = intraarticular space was fully outlined. Two multivariable ordered logistic regression analyses were performed to test the relationships between gender, age, and Grade, as well as between computed tomography (CT) findings and grade. Results In men, the totals by Grade were G0 = 8 (joints); G1 = 33; G2 = 3; and G3 = 0. In women, these were G0 = 4; G1 = 28; G2 = 22; and G3 = 10. The Grade was significantly higher in women and was also higher with age (P < 0.05). Regarding morphological features in CT, minor osteophytes increased the odds in favor of better Grades of arthrogram (odds ratio = 3.50). Substantial vacuum phenomena strongly increased the odds of better arthrograms (20.52). Conclusions Outlining the SIJ cavity fully is significantly more difficult in male patients of any age than in aged female patients. The presence of minor osteophytes and substantial vacuum phenomena on preprocedure CT scans can be reasonably reassuring to the practitioner that they are unlikely to encounter difficulties during injection.

High Grade Gliomas

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Background: Stroke is a great public health problem in Ethiopia. According to reports, in-hospital stroke mortality was estimated to be 14.7% in Ethiopia. Despite this, in this country researches done on factors associated with stroke sub-types were inadequate. Objective: To assess the Characteristics and risk factors associated with stroke sub-types among patients admitted to JUMC. Methods and materials: A retrospective cross sectional study was conducted from May 2017 to May 2018 in stroke unit of Jimma University Medical Center. A total of 106 medical charts of patients diagnosed with stroke were reviewed. Checklist comprising of relevant variables was used to collect data. SPSS version 21 was employed for data entry and analysis. Chi-square test was used to point-out association and difference among stroke sub-types. The data was presented using text, tables and figures. Result: From a total of 106 patients, 67(63.2%) were men. The mean ± SD of age was 52.67±12.46 years, and no significant association was found. Of all the patients, 59(55.6%) had ischemic strokes and 47(44.4%) had hemorrhagic strokes. The most common risk factor in the patients was alcohol use with a prevalence of 69.9%. Of all the risk factors, only sex, cigarettes smoking and dyslipidemia were significantly associated to sub-types of stroke. Conclusion: Ischemic stroke was the most common subtype of stroke. Sex of patient, cigarette smoking and dyslipidemia are significantly associated with the two stroke subtypes.

There is scarce evidence regarding the risk of weight loss and the effect of having registered dietitians (RDs) on staff in rehabilitation wards on weight loss. We aimed to examine the effects of RDs in Kaifukuki (convalescent) rehabilitation wards (KRWs) on the prevention of weight loss in adult patients. Data from 2-year nationwide annual surveys on KRWs in Japan were retrospectively analysed. Weight loss was defined as loss of ≥5% weight during the KRW stay. Risk of weight loss in class 1 KRWs (obligated to provide nutrition care) was compared with that in class 2–6 KRWs (not obligated). Risk of weight loss in class 2–6 KRWs with RDs was compared to those without. Overall, 17.7% of 39,417 patients lost weight. Class 1 KRWs showed a lower risk of weight loss than class 2–6 KRWs (17.3% vs. 18.5%, p = 0.003). KRWs with RDs showed a significantly lower incidence of weight loss than those without RDs (16.1% vs. 18.8%, p = 0.015). Class 1 KRWs and exclusively staffed RDs were independently associated with lower odds of weight loss (odds ratio = 0.915 and 0.810, respectively). Approximately 18% of KRW patients lost weight, and having RDs on staff can lower the risk of weight loss.

Abstract Introduction The purpose of this study is to determine the radiographic dimensions of the finger metacarpals and to compare these measurements with headless compression screws commonly used for fracture fixation. Materials and Methods We analyzed computed tomography (CT) scans of the index, long, ring, and small metacarpal bones and measured the metacarpal length, distance from the isthmus to the metacarpal head, and intramedullary diameter of the isthmus. Metacarpals with previous fractures or hardware were excluded. We compared these dimensions with the size of several commercially available headless screws used for intramedullary fixation. Results A total of 223 metacarpals from 57 patients were analyzed. The index metacarpal was the longest, averaging 67.6 mm in length. The mean distance from the most distal aspect of the metacarpal head to the isthmus was 40.3, 39.5, 34.4, and 31 mm for the index, long, ring, and small metacarpals, respectively. The narrowest diameter of the isthmus was a mean of 2.6, 2.7, 2.3, and 3 mm for the index, long, ring, and small metacarpals, respectively. Of 33 commercially available screws, only 27% percent reached the isthmus of the index metacarpal followed by 42, 48, and 58% in the long, ring, and small metacarpals, respectively. Conclusion The index and long metacarpals are at a particular risk of screw mismatch given their relatively long lengths and narrow isthmus diameters.

Negative Appendectomy Rate

(1) Background: Diagnosis of acute appendicitis (AA) remains challenging; either computed tomography (CT) is universally used or negative appendectomy rates of up to 30% are reported. Transabdominal ultrasound (TUS) as the first-choice imaging modality might be useful in adult patients to reduce the need for CT scans while maintaining low negative appendectomy (NA) rates. The aim of this study was to report the results of the conditional CT strategy for the diagnosis of acute appendicitis. (2) Methods: All patients suspected of acute appendicitis were prospectively registered from 1 January 2016 to 31 December 2018. Data on their clinical, radiological and surgical outcomes are presented. (3) Results: A total of 1855 patients were enrolled in our study: 1206 (65.0%) were women, 649 (35.0%) were men, and the median age was 34 years (IQR, 24.5–51). TUS was performed in 1851 (99.8%) patients, and CT in 463 (25.0%) patients. Appendices were not visualized on TUS in 1320 patients (71.3%). Furthermore, 172 (37.1%) of 463 CTs were diagnosed with AA, 42 (9.1%) CTs revealed alternative emergency diagnosis and 249 (53.8%) CTs were normal. Overall, 519 (28.0%) patients were diagnosed with AA: 464 appendectomies and 27 diagnostic laparoscopies were performed. The NA rate was 4.2%. The sensitivity and specificity for TUS and CT are as follows: 71.4% and 96.2%; 93.8% and 93.6%. (4) Conclusion: A conditional CT strategy is effective in reducing NA rates and avoids unnecessary CT in a large proportion of patients. Observation and repeated TUS might be useful in unclear cases.
