Epidemiological, clinical, and radiological comparison of adult and pediatric features in COVID-19: A scoping review.

OBJECTIVE: To assess epidemiological, clinical, and radiological characteristics of the coronavirus disease in children and adults. METHODS: The scoping review comprised search on PubMed and Scopus Cochrane databases from January 2020 to April 2021 for English-language articles dealing with clinical and radiological manifestations amongst children and adults affected by coronavirus disease. Two reviewers independently screened the titles and abstracts. RESULTS: Of the 389 studies initially identified, 39(10%) were reviewed in detail. Data suggested that children were less frequently affected by the coronavirus disease. The affected children showed milder disease with low case fatalities compared to the adults. CONCLUSIONS: There exists significant gaps in knowledge of clinical and radiological aspects of coronavirus disease, but the available scientific data showed that the disease seems to be unusual in children.

Intraoperative flexible nephroscopy during percutaneous nephrolithotomy: An 8 years' experience.

OBJECTIVES: To see the effect of intra operative antegrade flexible nephroscopy during Percutaneous nephrolithotomy on stone free rate. METHODS: We retrospectively reviewed electronic medical records of patients who underwent percutaneous nephrolithotomy from 2010 to 2017 for renal stones >2cm. Patients found eligible were divided in, Group-I who did not have intraoperative Flexible nephroscopy and Group-II who had flexible nephroscopy during percutaneous nephrolithotomy. All procedures were done by senior consultants. Variables like Mean age, side, stone size, skin to stone distance and Hounsfield unit were compared. Outcomes like Stone free rate, hospital stay and operative time were compared between the groups. RESULTS: The study included 248 patients, consisting 85 (34.3%) females and 163 (65.7%) males. Mean age ± SD was 45.8±13.8 years. Both group were similar in characteristics like mean age, stone size, skin to stone distance and Hounsfield units. The overall stone free rate was 71%. It was not significantly different between the groups, 76% in Group-II vs. 67% in Group-I. However stone free rate markedly improved with flexible nephroscopy in patients with staghorn calculi. Mean operative time and hospital stay were similar between the groups. CONCLUSIONS: Intraoperative flexible nephroscopy during percutaneous nephrolithotomy significantly increases stone free rate in patients with staghorn stones.

Knowledge, Attitude, and Barriers Toward ADRs Reporting Among Health-Care Professionals at Tertiary Care Health Settings in Peshawar, Pakistan: A Web Based Study.

Background: Underreporting of adverse drug reactions (ADRs) is considered a major determinant of poor ADR signal detection in Pakistan. Considering this, the study was proposed to evaluate healthcare professionals' (HCPs) knowledge attitude toward and the barriers that discourse ADRs reporting. Methods: A cross-sectional survey was distributed among HCPs in 3 major tertiary care facilities of Peshawar. A self-administered, 31 items questionnaire was circulated online to collect the required information. Relative index ranking was used to identify the top barriers to the ADR reporting process. Results: HCPs (n = 322) were requested, and over one-third (n = 122) responded. Of the total, 97 (79.5%) were males, and by designation, 59(48.4%) were resident medical officers. About 45% of the HCPs did not identify the appropriate pharmacovigilance (PV) definition. More than half of the HCPs (52.2%) distinguished the appropriate PV purpose. Nearly 80% HCPs did not know the acceptable reporting time frame, while 22.1% HCPs knew that regulatory body for ADRs does not exist in Pakistan. The majority (95.08%) of the HCPs either strongly agreed or agreed that reporting an ADRs is a professional obligation and all the HCPs were of the opinion that PV should be taught in detail to HCPs. Exploring the barriers, it was identified that the key barriers to ADRs reporting were "unavailability of professional environment to discuss ADRs," Relative Importance Index (RII) = 0.813, "lack of incentives for reporting" (RII = 0.774), "lack of knowledge regarding reporting" (RII = 0.693), and "insufficient knowledge of pharmacotherapy in detecting ADRs" (RII = 0.662). In addition to these, "complicated reporting forms" (RII = 0.616), "lack of motivation for reporting ADRs" (RII = 0.610), and "absence of professional confidence" were seen as major hindrances in effective reporting of ADRs (RII = 0.598). Conclusion: Concerning PV and ADR reporting poor knowledge was noted. However, the majority of the HCPs showed an explicit attitude regarding ADRs reporting. The majority of the HCPs disclosed unavailability of professional environment to discuss about ADRs, lack of incentives, and how to report the main factors hindering the ADRs reporting. It is emphasized that health authorities carve out a niche for a well purposeful PV center and pledge educational activities and trainings for increasing understanding and approaches regarding reporting of ADR.

The migraine epidemic among medical students: a call for action.

Migraine is characterized by recurrent headaches of moderate-to-severe intensity and poses a significant challenge for medical students. This is a narrative literature review using PubMed and Scopus databases. This study examines how common migraine is in this group and suggests working together to address how it affects students' well-being and chances of succeeding as a medical professional in the future. Early diagnosis by licensed medical specialists is essential for effective management of migraine. To address this, the authors propose a multifaceted strategy. By including direct education on migraines in medical school curricula, future doctors will be better prepared to treat patients with comparable problems and manage their own migraines. Students with migraines can also benefit greatly from creating a supportive learning environment through staff training, accommodating academic policies, and providing easily available healthcare resources. In addition, this technology may be helpful. Apps for relaxation and migraine tracking can help students better manage their condition. Long-term success requires cooperation among all parties. By promoting cooperation among medical schools, student associations, healthcare practitioners, and governmental organizations, the authors can raise public awareness of migraine, make pertinent resources easier to access, and create evidence-based solutions specially designed to meet the needs of medical students who experience migraine. In the end, putting student well-being first and working together to put these solutions into practice can enable aspiring doctors to succeed at both personal and professional levels.

Cholecystocolonic fistula secondary to ascending colon diverticular disease: A case report.

Cholecystocolonic fistula occurring as a complication of colonic diverticular disease is a rarely encountered clinical entity in which the patient may remain asymptomatic or present with vague abdominal or systemic symptoms. Imaging studies are usually not very reliable or effective in detecting direct communication between gallbladder and colon. However, indirect signs such as pneumobilia, gallstones, gallbladder adherent to colon and colonic diverticulosis may help reach the diagnosis. Treatment of cholecystocolonic fistula in symptomatic patients is usually surgical. However, in asymptomatic patients or patients with risk factors and comorbidities, non-surgical options such as conservative management or biliary stenting can be considered.

IgG4-related inflammatory pancreatic head pseudotumor mirrors pancreatic head tumor: A novel case series with a review of the literature.

Key Clinical Message: In this noteworthy case series regarding pancreatic pseudo tumors, we intend to spread knowledge among physicians for the diagnostic and therapeutic approach and eventual disease prognosis. Abstract: Inflammatory pseudotumor of pancreatic head greatly mimics pancreatic head tumor. One of them is IgG4-related pancreatic disease, which is commonly mistaken as neoplastic disease on imaging. In our novel case series, we report three cases of IgG4-related pancreatic head pseudotumor with patients ranging from 35 to 72 years of age. Patients presented with jaundice and abdominal pain. Alongside initial laboratory workup, abdominal CTs and serum IgG4 levels were also obtained. Imaging features in conjunction with IgG4 levels confirmed the diagnosis of IgG4-related autoimmune pancreatitis. Pancreatic pseudotumors are notorious for being often reported as real tumors. Through our noteworthy case series, we intend to highlight the imaging features and laboratory markers that are crucial in such cases to avoid invasive procedures.

Duodenal stricture secondary to IgG4-related chronic sclerosing duodenitis-A case report with review of the literature.

Key Clinical Message: This case highlights the importance of a definite diagnosis of an IgG4-related chronic sclerosing duodenitis based on histological and radiological findings to rule out any malignancy in the mass. While dealing with patients having concentric duodenal thickening resulting in stricture formation, one should think of inflammatory etiology as well. IgG4-related disease is one of these inflammatory disorders where we see soft tissue thickening without a large mass or any associated lymphadenopathy as in our case. Abstract: Immunoglobulin G4-related disease (IgG4-RD) is distinguished as an infiltration of IgG-4-positive plasmacytes involving inflammatory lesions across multiple organs which is accompanied by raised IgG4 levels in the serum. Several inflammatory disorders are recognized as part of the IgG4-RD family based on shared histopathological features, which include Mikulicz's disease, chronic sclerosing sialadenitis, or Riedel's thyroiditis. Our case highlights a distinctive presentation of IgG4-related diseases; a 58-year-old man presenting with duodenal stricture highly suspicious of a duodenal mass/ampullary mass later found to be due to IgG4-related sclerosing duodenitis with negative malignancy on biopsy. We present the diagnostic challenges faced and relevant findings noted.

Kawasaki disease with profound systemic vascular involvements: An insightful pediatric case.

Key Clinical Message: Kawasaki disease (KD), a self-limiting vasculitis, can present with a broader spectrum of vascular involvements, necessitating early recognition and prompt management. This case exemplifies the importance of involving multiple teams on board in managing complex presentations of KD. It also highlights the importance of close monitoring for the progression of the disease spectrum as well as family education to ensure favorable outcomes. The case also emphasizes the importance of long-term follow-up and further research to understand the prognosis, early screening tools, and possible complications due to multi-organ involvement in KD along with their management strategies. Abstract: Kawasaki disease (KD) is a multisystem vascular inflammatory syndrome, which predominantly affects the small and medium vessels in children within the age group of less than 5 years. The most threatened complication is the development of coronary artery aneurysms (CAAs). We present an extremely rare case of KD in a 2-month, 21-day-old male infant with extensive vascular involvement, expanding the disease spectrum beyond the involvement of coronary arteries. These included aneurysmal dilatations of both internal carotid arteries, the descending aorta, bilateral multilevel intercostal arteries, coeliac artery, superior mesenteric artery, and both renal arteries. Implementing a multidisciplinary approach with early treatment via intravenous immunoglobulin (IVIG) and dexamethasone proved to be most effective in the patient's management. Despite unique challenges such as severe coronary dilation and pseudomonas sepsis during the special care, the patient was stabilized and discharged after 11 days of hospital stay, highlighting the importance of early prompt management and a centered approach to evaluate in a broader spectrum. This case emphasizes the importance of long-term follow-up and further research to understand the prognosis, early screening tools, and possible complications due to multi-organ involvement in KD along with their management strategies.

Pseudoaneurysm of cystic artery stump after laparoscopic cholecystectomy managed successfully with branch hepatic artery embolization using jail technique.

An unusual manifestation caused by cholecystitis, infection, or iatrogenic damage after cholecystectomy is a pseudoaneurysm of the cystic artery. We report this rare illness in a 64-year-old man who visited the emergency room with hematemesis and anemia. The patient initially experienced acute cholecystitis and then underwent a laparoscopic cholecystectomy following which he developed a cystic artery pseudoaneurysm, secondary to infected fluid collection. Based on the patient's history and contrast-enhanced computer tomography abdomen, a diagnosis of pseudoaneurysm of the cystic artery was made. Angioembolization of the hepatic artery branch was performed to occlude the pseudoaneurysm.

Does sevoflurane sedation in pediatric patients lead to "pseudo" leptomeningeal enhancement in the brain on 3 Tesla magnetic resonance imaging?

BACKGROUND: Prominent leptomeningeal contrast enhancement (LMCE) in the brain is observed in some pediatric patients during sedation for imaging. However, based on clinical history and cerebrospinal fluid analysis, the patients are not acutely ill and do not exhibit meningeal signs. Our study determined whether sevoflurane inhalation in pediatric patients led to this pattern of 'pseudo' LMCE (pLMCE) on 3 Tesla magnetic resonance imaging (MRI). AIM: To highlight the significance of pLMCE in pediatric patients undergoing enhanced brain MRI under sedation to avoid misinterpretation in reports. METHODS: A retrospective cross-sectional evaluation of pediatric patients between 0-8 years of age was conducted. The patients underwent enhanced brain MRI under inhaled sevoflurane. The LMCE grade was determined by two radiologists, and interobserver variability of the grade was calculated using Cohen's kappa. The LMCE grade was correlated with duration of sedation, age and weight using the Spearman rho rank correlation. RESULTS: A total of 63 patients were included. Fourteen (22.2%) cases showed mild LMCE, 48 (76.1%) cases showed moderate LMCE, and 1 case (1.6%) showed severe LMCE. We found substantial agreement between the two radiologists in detection of pLMCE on post-contrast T1 imaging (kappa value = 0.61; P < 0.001). Additionally, we found statistically significant inverse and moderate correlations between patient weight and age. There was no correlation between duration of sedation and pLMCE. CONCLUSION: pLMCE is relatively common on post-contrast spin echo T1-weighted MRI of pediatric patients sedated by sevoflurane due to their fragile and immature vasculature. It should not be misinterpreted for meningeal pathology. Knowing pertinent clinical history of the child is an essential prerequisite to avoid radiological overcalling and the subsequent burden of additional investigations.

Wandering spleen with acute torsion mimicking an adnexal mass.

Wandering spleen manifests when the splenic ligaments are underdeveloped, or become lax, thereby allowing the spleen to relocate from its anatomical site to more distant areas. During such movements, torsion of the long splenic peduncle is common, which can lead to symptoms of acute abdomen and further complications such as infarction. It is typically seen in children and young females. Our report presents a case of a 22-year-old female presenting to the ER with complaints of severe pain in the abdominal region. On ultrasound, there was suspicion of an adnexal mass, which was later confirmed to be a misplaced spleen in the lower abdomen, with torsion, fat stranding, and splenic vein thrombosis, as revealed by enhanced CT abdomen and pelvic MRI. It was followed by an emergency splenectomy. As wandering spleen presents nonspecifically and is a rare condition, it is important to consider wandering spleen when patients present similarly to this case, to prevent misdiagnosis and to deliver surgical treatment quickly to preserve the spleen.

The tendency of segmental distribution of hepatic metastasis according to couinaud classification: a comparison of portal versus systemic route of metastatis due to primary colorectal and breast tumors.

Objective: The liver is the commonest site of metastatic disease for patients with colorectal cancer (CRC), with at least 25% of patients developing liver metastasis (LM) during their illness. About 50% of patients diagnosed with metastatic breast cancer develop LM, and 5-12% of these patients develop LM as the main site of breast cancer recurrence. This study aims to determine the frequency of segmental distribution of LM seeding from portal versus systemic routes of dissemination due to primary CRC and breast carcinoma, respectively. Material and methods: This retrospective study was conducted in a tertiary care teaching hospital in Pakistan. Ethical approval was taken from the institutional review board. A total of 587 patients were included in the study with 297 CRC patients with LM and 300 breast carcinoma patients with LM. Segment I involvement was excluded from the calculation because of the dual blood supply. Patients' detailed demographics and other information were collected on a predesigned proforma. The authors evaluated axial and multiplanar reformatted computed tomography images for LM and CRC metastasis. Data analysis was done using SPSS version 25. P value less than or equal to 0.05 was considered statistically significant. Results: A study population of 587 patients was employed that comprised 287 CRC and 300 breast carcinoma patients. There were 179 (30.5%) male and 408 (69.5%) female patients. The mean age of patients was 54.9±13.3. The study revealed that 204 (34.8%) CRC patients showed right lobe (V, VI, VII, VIII) and 83 (14.1%) CRC patients showed left lobe involvement of metastasis while 192 (32.7%) breast carcinoma patients showed right lobe involvement and 108 (18.4%) breast carcinoma patients showed left lobe involvement in metastasis (P=0.02). We also found 40 (6.8%) colorectal and 55 (9.4%) breast carcinoma patients showed left lateral segment (II, III) involvement. Medial segment involvement (IV) was seen in 43 (7.3%) CRC patients and 53 (9%) breast carcinoma patients (P=0.03). Conclusion: The right hepatic lobe is the predominant site of metastasis independent of the portal or systemic route of dissemination in primary carcinoma. Moreover, in left lobe metastasis medial segment (IV) is more affected in CRC while the lateral segment (II, III) is more affected in breast carcinoma.

Testicular choriocarcinoma with small bowel metastasis and active gastrointestinal bleeding.

Testicular choriocarcinomas make up less than 1% of all germ-cell tumors and are highly malignant, attributable to hematogenous spread. While the most common sites of metastasis are the lungs and liver, metastatic spread to the gastrointestinal tract is rare wherein patients may present with GI distress or even an upper GI bleed. In this report, we present a case of known testicular choriocarcinoma in a 40-year-old male who presented to the emergency room with severe anemia and a suspected upper GI bleed.

High-altitude cerebral edema manifesting as T2/FLAIR hyperintensity and microbleeds in the white matter on MRI brain.

High-altitude cerebral edema is a rare type of acute mountain illness characterized by consciousness disruption and truncal ataxia. Here we discuss a 40-year-old nondiabetic, nonsmoker male who went on a tour to Nanga Parbat. On returning home, the patient developed symptoms of headache, nausea, and vomiting. His symptoms worsened with time and he developed lower limb weakness and shortness of breath. Later, he underwent a computerized tomography chest scan. On the basis of CT scan findings, the doctors decided that the patient was suffering from COVID-19 Pneumonia despite having negative COVID-19 PCR tests multiple times. Later, the patient presented to our hospital with similar complaints. MRI of the brain revealed T2/fluid-attenuated inversion recovery hyperintense and T1 hypointense signals in the bilateral semioval centrum, posterior periventricular white matter, and corpus callosum genu, body, and splenium. These abnormal signals were discovered to be more evident in the corpus callosum's splenium. Moreover, susceptibility-weighted imaging revealed micro hemorrhages in the corpus callosum. This verified the diagnosis that the patient is suffering from high-altitude cerebral edema. Within 5 days, his symptoms resolved and he was discharged with full recovery.

Clinical Utility of S.T.O.N.E, Guy's Scoring System, and Renal Stone Complexity Scoring in Predicting Outcome of Single-Tract Percutaneous Nephrolithotomy.

BACKGROUND: Several imaging-based scores have been developed to predict postoperative stone-free state (SFS) and complications. This study aimed to assess the accuracy of the S.T.O.N.E., Guy Scoring System (GSS), and Seoul National University Renal Stone Complexity (S-ReSCS) scores in predicting the outcomes of single-tract percutaneous nephrolithotomy (ST-PCNL). This scoring system holds paramount importance for low-income and low-middle-income countries (LMICs), as it is inexpensive and cost-effective for the healthcare system. METHODOLOGY: This retrospective study was carried out with 147 participants. Based on the preoperative computerized tomographic (CT) scan, each patient's S.T.O.N.E. score, GSS, and S-ReSCS were recorded. The modified Clavien grading system was used to document intra- and postoperative complications. RESULTS: The mean age of the sample population was 45 years. SFS was achieved in 110 (74.8%) patients. The number of calyces involved (p = 0.008), S.T.O.N.E. scoring (p = 0.001), GSS (p = 0.008), and S-ReSCS (0.001) correlated well with the SFS. Forty-nine (33.33%) patients developed complications. The most common complications fell within Clavien grade II. No statistical significance was noted between the S.T.O.N.E. score, GSS, and S-ReSCS with the modified Clavien grading system. CONCLUSION: The S.T.O.N.E. scoring, GSS, and S-ReSCS have a high predictive value for achieving SFS in ST-PCNL. In addition, findings from LMICs are comparable with those from the rest of the world.

Use of National Institute for Health and Care Excellence head injury guidelines among patients with delayed presentation after head trauma can lead to missed traumatic brain injury: a 5-year institutional review.

Introduction: In 2014, traumatic brain injury (TBI) caused 3 million ER visits, hospitalizations, and deaths in the US. The National Institute for Health and Care Excellence (NICE) guidelines, initially generated using data from patients presenting within 24 h of head trauma, are used to determine the need for head computed tomography (CT) scan in patients after 24 h. The authors wanted to determine the proportion of CT scans for head trauma performed at our center in late presenters (>24 h after head trauma), the incidence of intracranial pathology in early (24 h) versus late (>24 h) presenters, and the sensitivity of the NICE guidelines for TBI in these two subpopulations. Methods: A retrospective chart review was conducted at a tertiary care center in Karachi. All people (>16) who had a head CT for head trauma from 2010 to 2015 were included. Age, sex, primary diagnosis, comorbid disorders, mechanism-of-injury, duration (in hours) from head trauma to presentation, site, and extent of injury (injury severity scale), hospital stay, number and details of surgical procedures, CT scan findings, other injuries, and mortality were recorded. Means were compared using the Independent Sample t-test, while categorical variables were compared using χ2. Multivariate logistic regression analyses were used to identify TBI predictors. Results: The authors found 2009 eligible patients; seven were excluded due to incomplete medical records. The final statistical analysis comprised 2002 head trauma patients. Overall, 52% of early and late presenters had severe injuries, and 2.3% died. 32.2% of patients with head trauma had CT after 24 h. Early presenters were 46.7% traumatized, while late presenters were 63%. The NICE guidelines were 93% sensitive for early presenters and 83% for late presenters with traumatic intracranial injury. Conclusion: Patients coming to the emergency department after 24 h of head trauma are a large proportion of the overall head trauma population. The NICE guidelines for late-presenting head injuries are less sensitive and may overlook intracranial injuries if imaging is not performed.

Prevalence and antimicrobial susceptibility of Acinetobacter spp. in a tertiary care hospital in Peshawar: a cross-sectional study.

Acinetobacter spp. have been a primary cause of nosocomial infections worldwide, causing significant morbidity and mortality, especially in Pakistan. The purpose of this study was to investigate the trend of antimicrobial resistance over a 5-year period in a tertiary care hospital in Pakistan. Methods: A retrospective cross-sectional study regarding the occurrence and antimicrobial resistance of Acinetobacter spp. recovered from clinical specimens that were referred to the Pathology Laboratory of Northwest General Hospital, Peshawar. The data from 2014 to 2019 was recorded and analyzed by the laboratory. Sociodemographic characteristics and laboratory record data was analyzed using SPSS, version 25. A chi-square test was applied to see the significance. Results: Of 59 483 clinical samples, Acinetobacter baumannii strains were detected in 114 of them. The majority of the clinical samples were from blood (89.5%) followed by sputum (7.9%), wound swab (1.8%), and bone marrow (0.9%). A. baumannii has been found in 52 men (67.53%) and 28 women (75.67%), with an overall risk of 0.669 times. In 76 men (98.70%), sensitivity for ertapenem (99.1), colistin (96.49), and tigecycline (78.9%) were also observed which indicated the potential viability of these drugs to treat multidrug-resistant (MDR) Acinetobacter infections. The male-to-female risk ratio was 0.98 for colistin and 0.71 for amikacin. Conclusion: Increased frequency of MDR supports the need for continuous surveillance to determine the prevalence and evolution of MDR Acinetobacter spp. in Pakistan. Colistin, tigecyclines, and ertapenem remain the possible line of drugs to treat MDR Acinetobacter.
