The role of ultrasonography in diagnosis of neuralgic amyotrophy.

To investigate the value of high frequency ultrasound in diagnosis of neuralgic amyotrophy. From January 2010 to December 2020, the ultrasonographic images of 117 patients with neuralgic amyotrophy diagnosed by the Department of Neurology and hand & foot surgery of Shandong Provincial Hospital Affiliated to Shandong First Medical University were retrospectively analyzed. The ultrasonographic features were summarized. High frequency ultrasound could clearly show the degree of the affected nerves: No ultrasonic findings were found in 12 cases (10%). The affected nerves were thickening and hypoechogenicity with loss of normal fascicular definition in 28 cases (24%). The affected nerves showed hourglass-like changes, including constriction and torsion in 77 cases (66%). In addition, ultrasound can determine the extent of the lesion, and microvascular imaging can display small blood flow signal within the nerve. There was a significant statistical difference between the diameter of the thickened nerve fascicle and the diameter of the nerve fascicle at the corresponding site of the contralateral normal limb. High frequency ultrasound is a valuable imaging method for diagnosis of neuralgic amyotrophy.

Role of Ultrasonography in Diagnosis of Appendicitis and Its Correlation with Age

Background: Inflammation of appendix is most collective medical condition. Appendicitis can develops serious when it rupture. Perforation is additional common problem in many aged patients. Aim: The goal of study was to classify diagnosis of appendicitis on sonography and its correlation with age. Methodology: Cross-sectional study was directed on a group of patients who had appendicectomy at the same time. All data was summarised, including the patients age, sex, clinical findings, and ultrasound findings. Across-sectional assessment of 98 patients under age of 35 who required a physical exam and ultrasound findings was conducted. Individuals of various ages were divided into groups. Demography, clinical presentation, and diagnosis were compared between the groups. The diagnosis was made through clinical examination followed by ultrasonography. Different age groups are compared to ultrasonography findings. Results: During study, total number of patients were 98 under the age of 35 years with suspected appendicitis, 42males and 56 females. Appendix found in 74indiviuals, 47females and 27 males. Of all indiviualss, 74 were diagnosed by medical valuation and ultrasound findings. By performing ultrasound it has been evaluated that all patients had appendicitis. From total, 47 were females and 27 were male patients. Appendix was found in total 74 cases with associated other signs of tenderness. According to gender females were found more positive results of disease than males. Out of 98 patients 47 females with ultrasound positive results and 27males were with ultrasound positive results. To find out the relationship between age groups, gender and appendicitis results we applied chi square test. Output pf chi square test for age show that there is same relationship exist between different age groups and appendicitis result. The relationship was significant and we observed p value (0.045) which is less than (0.05) there is same relationship exist between different ......

Application of ultrasonography to Neuro-COVID-19

Aim: The aim of this study is to evaluate the role of ultrasonography in diagnosis and treatment of COVID-19, the disease caused by severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), with particular reference to the symptoms that are frequently observed in Neuro-COVID-19, a term that indicates the plethora of short- and long-term neurologic and psychiatric manifestations caused by, or associated with the disease. In a significant percentage of cases, neuro-psychiatric symptoms persist after recovery and long-term sequelae have been reported. SARS-CoV-2 can infect the brain through different routes and the damage can be direct, that is due to the virus itself, or indirect, that is associated with abnormal immune responses, inflammation, and hypoxia. Methods: In this study, the brain was studied by transcranial ultrasonography. Analysis of brain specimens obtained from autopsy demonstrated the presence of the virus in a minority of cases and this leads to hypothesize that SARS-CoV-2 may hide in sanctuary sites in the central nervous system in analogy with what observed for HIV. The existence of sanctuary sites for SARS-CoV-2 has the potential to decrease the efficacy of antiviral therapies or vaccination and may even prevent complete eradication of SARS-CoV-2 from the infected organism. Results: Transcranial ultrasonography demonstrated significant movements of the brain associated with the respiratory cycle. In 2017, a diagnostic and therapeutic procedure was proposed with the goal of identifying and treating pathogens hiding in sanctuaries that elude diagnosis and therapy. This procedure is based on clinical evaluation, diagnostic ultrasonography, therapeutic ultrasounds, and laboratory analyses. Conclusions: Here, it is demonstrated that application of transcranial ultrasonography to Neuro-COVID-19 requires a specific adaptation that takes into account brain movements synchronous with breathing as well as the sensitivity of SARS-CoV-2 to ultrasounds.

Role of ultrasonography in diagnosis of adnexal masses

Background Adnexal masses are considered one of the most common disorders in gynecology. Ultrasound remains the most widely used imaging modality to differentiate benign from malignant adnexal masses. Patients and methods This prospective study was conducted upon 50 female patients with 56 adnexal lesions. All patients were evaluated by either transabdominal ultrasonography, transvaginal ultrasonography, or both. All patients were evaluated by gray-scale ultrasound. Color Doppler examination was performed in certain cases with solid components. This study was approved by the Ethics Committee, and all patients gave their informed written consent before inclusion in the study. The radiological and histopathological results were collected then statistically analyzed. Results Our study showed that ultrasound had a sensitivity of 85.7% and a specificity of 90.5% with an overall accuracy of 89.3% in differentiation between benign and malignant lesions. The most significant ultrasound parameters suggesting malignant criteria of adnexal masses in our study were thick wall more than 3 mm, thick papillary projection, and thick septae more than 3 mm on gray-scale ultrasound, resistive index less than 0.5, and central distribution of vessels at color Doppler. Conclusion Ultrasound is recommended to be a very useful highly diagnostic and a reliable modality with good sensitivity and specificity for the diagnosis of adnexal masses.

To study the role of ultrasonography in diagnosis, management and prevention of incomplete surgical release in patient’s of de Quervain’s disease

Background: Fritz de Quervain, in 1895, described the tenosynovitis of first extensor compartment tendons of abductor pollicis longus and extensor pollicis brevis. Clinically characterized by pain and swelling over the radial styloid process, a positive finkelstein test and accompanied by a palpable thickening of the tendon sheaths and painful wrist and thumb movements. The diagnosis is usually clinical and the treatment varies from conservative to surgical decompression of the first extensor compartment. Materials and Methods: This is a prospective study of 28 patients of de Quervain’s tenosynovitis involving 30 wrists treated in Father Muller Medical College and Hospital, Mangalore between 1 September 2015 and 30 November 2016. Results: A total of 28 patients and 30 wrists were examined in this study. The disease was found to be more common in fourth and fifth decade of life. In our study there were 23 females out of total 28 patients. Right wrist was more commonly affected than the left. Out of 28 patients 18 underwent surgery. Total 20 wrists out of 30 were surgically decompressed. Ultra sound showed the presence of single tendon of APL in 16 wrists (53.3%) and more than 1 tendon in 14 cases (46.7%). Out of 20 wrists which were operated 12 had 2 slips of APL and 8 had one slip of APL. Ultrasonography correctly identified the number of tendons in all except one case, in which it under diagnosed the number of tendons. Conclusion: Though ultrasound could not pick up a sub compartment it can still prevent the complication of incomplete surgical release as it correctly identifies the number of tendons. We strongly recommend looking for a sub compartment when the number of tendons seen on ultrasound is more than that found intraoperatively.

Role of ultrasonography in diagnosis of solid space occupying lesion in the liver correlation with FNAC.

This cross sectional study was carried enrolling 47 subjects with suspected solid liver mass, in the Department of Radiology and Imaging, Dhaka Medical College Hospital, Dhaka, over a period of twelve months. The aim of this study was to evaluate the diagnostic usefulness of transabdominal ultrasonography in the diagnosis of solid SOL in the liver. Majority of the respondents (42.55%) were found between 41-60 years of age. Five (10.63%) subjects were found below 20 years of age. There were 31 men (65.95%) and 16 women (34.05%). Majority of the metastasis were multiple (85%), hypoechoic (35%) and only 15% had internal calcifications. HCC was single lesion (61.53%) with hyperechoic (38.35%) echogenicity, with a central halo (76.92%) and 15.38% had internal calcifications. Majority of the cholangiocarcinoma were solitary (80%), hypoechoic (60%) and 60% had internal calcifications. Hepatoblastoma were solitary and had calcifications (60%) with mixed echogenicity (60%). Majority of the adenomas were solitary (80%), hypoechoic (60%) and only 20 % had internal calcifications. The validity of transabdominal sonography for the diagnosis of metastasis was confirmed by calculating sensitivity (100%), specificity (96.42%), accuracy (97.87%), positive (95%) and negative predictive (100%) values by using the standard formula given. The sensitivity, specificity, accuracy, positive and negative predictive values for HCC were 92.3%, 97.05%, 95.74%, 92.3% and 97.05% respectively. The sensitivity, specificity, accuracy, positive and negative predictive values for cholangiocarcinoma and hepatoblastoma were 80%, 97.61%, 95.74%, 80% and 97.61% respectively. Sensitivity, specificity, accuracy, positive and negative predictive values were 80%, 100%, 97.87%, 100% and 97.67% respectively for adenoma. From the study result it was concluded that transabdominal ultrasonography could be reliable, non- ionizing and relatively cheap procedure for diagnosis solid hepatic mass lesion.

Comparative evaluation of the role of Sonography in diagnosis of Acute Appendicitis versus Surgeon`s clinical impression

A randomly selected group of patients presented in Accidents & Emergency department of Jinnah hospital Lahore with complaint of acute lower abdominal pain were subjected to abdominal sonography and those positive for acute appendicitis on ultrasound examination were operated. Another group of randomly selected patients with acute lower abdominal pain in Emergency department were clinically evaluated for acute appendicitis and surgery was done based on clinical impression (history and classical signs for acute appendicitis). Ultrasound examination showed the following parameters. Sensitivity 71.8%, specificity 62.5%, PPV 88.4%, NPV 35.7%. Clinical evaluation showed the sensitivity of 95.2%, specificity 77.7%, PPV 90.9%, NPV 87.5%. It was concluded on the basis of the results that clinical evaluation of the patient is more sensitive in correctly categorizing those who need appendicectomy than the ultrasound examination. Although the latter can be used in suspected cases and to rule out other pathological conditions resulting in acute abdomen. Limitations: Clinical judgment to a large extent rest on the experience and expertise of the surgeon and so is the quality of sonographic results, which depend on experience of sonographer & quality of ultrasound machine.

Role of abdominal Ultrasonography in diagnosis of acute abdomen

Introduction: Ultrasonography has established itself as an invaluable tool in surgery. In surgical practice, abdominal pain is perhaps the most common symptom encountered and almost in every case of abdominal pain surgeon prefers to use the ultrasound to confirm the diagnosis. Although physical examination of the patient is the most important part in proper diagnosis many a time some positive help is required in the form of investigations especially ultrasonography. Methods: This was a study of hundred patients carried out at a tertiary care hospital admitted with complaints of severe abdominal pain except those with a history of trauma or with a history of chronic abdominal pain. Clinical history, physical examination, ultrasonography, per operative findings and histo-pathological examination were used to come to a final conclusion. Result: In this study ultrasonography was diagnostic in 78% of patients. Two patients were misdiagnosed and in 20 patients other investigations were required for the confirmation of diagnosis. The sensitivity and specificity of ultrasound in diagnosing acute appendicitis, renal calculus, liver abscess, mesenteric lymphadenitis, acute pancreatitis and ovarian cyst was 100% and in calculus cholecystitis it was 93.75% and 100% respectively. Conclusion: Ultrasonography is superior in organ system imaging. It helps in showing organ specific lesions and its accurate measurement which is helpful in follow up and response to treatment. Ultrasonography is also helpful in diagnosing alternative disease and to reduce negative laparotomy rate.

INTRODUCTION: Acute appendicitis is the commonest emergency met in surgical practice. The clinical features sometimes being non-specific and list of differential diagnosis is too long. Diagnosis being particularly difficult in females due to associated gynaecological and obstetric conditions. The aim is to reduce unnecessary laparotomies and incidence of appendiceal perforation which is associated with significant post-operative morbidity. Reported approaches to achieve this objective include emergency laparotomy, Ultrasonography (USG), scoring system, CT scan etc. In peripheral areas USG remains most widely available and preliminary investigative for establishing definitive diagnosis in addition to clinical suspicion. AIM: Clinical evaluation and role of ultrasonography in patients of acute appendicitis in a rural hospital. OBJECTIVES: To study clinical profile of acute appendicitis. Role of USG in diagnosis of acute appendicitis. METHODS: 50 patients of acute abdomen suspected to have acute appendicitis, of all age groups and both sexes, admitted with cardinal features of acute appendicitis like pain in abdomen (Right iliac fossa), vomiting, and fever were included in this study. Patients were studied according to the Proforma. Surgeons made a final clinical diagnosis on the basis of clinical impression and USG information. All the patients diagnosed as acute appendicitis (without any lump formation in RIF) were treated surgically and diagnosis was confirmed histopathologically. Acute appendicitis was studied with special reference to clinical findings and ultrasonographic findings. Use of ultrasonography in the diagnosis of acute appendicitis was evaluated. CONCLUSION: USG remains most cost effective, efficient and valuable investigation for acute appendicitis in rural settings. The use of USG in suspected acute appendicitis should be complement to but not replacing clinical assessment.
