Pott’s Puffy tumor (PPT) is a rare complication of frontal sinusitis, involving a subperiosteal abscesses with associated osteomyelitis of the frontal sinus anterior table. It mainly affects children and adolescents but can also occur in adults. It presents with localized forehead swelling, pain, fever, headache, and sometimes intracranial complications like epidural or subdural abscesses [1,2]. The standard treatment for PPT typically involves surgical drainage under general anesthesia and broad-spectrum intravenous antibiotics. During the coronavirus disease 2019 (COVID-19) pandemic (March–June 2020), delayed surgeries and resource limitations led to the use of minimally invasive techniques [3] such as needle aspiration without general anesthesia. In this study, we present three adult PPT cases from Nottingham University Hospitals, United Kingdom, treated with early abscess aspiration during this period.

We conducted retrospective study of PPT cases presented during the early COVID-19 pandemic. Following patients’ consent, case notes were reviewed for baseline demographics, previous treatments, presenting symptoms, and examination findings.

Background: Prior to the coronavirus disease 2019 (COVID-19) pandemic, bronchiolitis caused by respiratory syncytial virus (RSV) was primarily observed during the winter months. Recently, however, an increase in incidence during the warmer months has been noted. This trend suggests an interaction between RSV and coronavirus, as well as the impact of public health measures, such as hand hygiene, mask-wearing, and social distancing.

Objectives: To characterize bronchiolitis cases in children under 2 years old caused by RSV during the COVID-19 pandemic in Israel from 2018 to 2022.

Methods: We conducted retrospective study by analyzing medical records of children hospitalized with bronchiolitis from January 2018 to December 2022. A comparison was made between cases before and after the first COVID-19 lockdown.

Results: A total of 922 children with bronchiolitis were studied: 276 cases occurred before the lockdown and 646 cases afterward. We found an increase in bronchiolitis frequency during the summer following the lockdown and a decrease during the winter (P < 0.0001). In addition, there was a shift in the pathogenic profile, with a notable rise in mixed infections after the lockdown (P < 0.0001). No significant differences in clinical presentation were observed between pre- and post-lockdown periods.

Conclusions: There was a change in bronchiolitis seasonality after the lockdown, with a significant increase in cases during the summer and a rise in mixed infections. Further studies are needed to assess whether this shift is a lasting consequence of the pandemic or a temporary change.

Background: Coronavirus disease-2019 (COVID-19) chest computed tomography (CT) involves ground-glass opacity (GGO) and denser consolidations, which are crucial for diagnosis.

Objectives: To determine optimal window settings for characterization and detection of GGO and dense consolidation on CT imaging in COVID-19 patients using a Simplex-based approach.

Methods: The study included 54 conventional CTs of COVID patients in two phases. First, CT images of 14 patients with GGO and 4 with dense consolidation were included. Seven radiologists evaluated representative images in different windows of varied width and center. They were graded for adequacy of characterization and detection. A Simplex algorithm was used to iteratively determine the optimal window settings. Surface response maps expressing the relationship between window settings and overall reader grades were constructed. Next, the reviewers compared manufacturer recommendations to the new optimal windows found on CT images of 40 patients.

Results: Overall, 12 different window settings were evaluated over a total of 1176 reads. Optimal characterization and detection of pure GGO was seen with a center of 630 HU and width 1460 HU, producing higher grades for both detection and characterization than the manufacturer window settings (P = 0.005). Optimal windowing for dense consolidation was like manufacturer measures (-585 HU and 1800 HU). In phase 2, an overwhelming preference of 78% favoring the optimal window compared to conventional settings was found.

Conclusions: GGO lung opacities characteristic for COVID-19 can be best seen using a lower CT windowing width than the manufacturer's recommendations, unlike denser consolidations, possibly due to differences in underlying pathophysiology.

Background: High prevalence of hepatitis C (HCV) among people with severe mental illness (SMI) is attributed mostly to current or past intravenous (IV) drug use. However, such history may disappear from patient files over time, especially in chronic SMI with prolonged psychiatric admissions.

Objectives: To explore HCV and SMI cross-morbidity (HCV/SMI) in a hospitalized population.

Methods: In this observational, retrospective, historical computerized study we examined prevalence, characteristics, and outcomes of patients with HCV/SMI compared to HCV alone in patients admitted to an Israeli hospital 1 January 2005 to 31 December 2020.

Results: Of 1638 eligible HCV patients, 219 (13.4%) were HCV/SMI. Significantly more native Israelis showed HCV/SMI than HCV alone (36.1% vs. 18.1%, P = 0.013) and history of IV drug use (60.3% vs. 32.4%, P < 0.001). Among Israeli natives, more Jews were SMI/HCV compared to HCV only (67.1% vs. 45%, P < 0.01). Among non-native Israelis, immigration age was lower in SMI/HCV compared to HCV only (27.97 vs. 37.23 years, P < 0.001). No differences were found in mortality or cirrhosis, although HCV/SMI patients experienced earlier mortality compared to HCV alone (61.42 ± 14.3 vs. 72.8 ± 14.6 years, P < 0.001). Cirrhosis among HCV/SMI patients was a risk factor for early mortality (hazard ratio 5.528, 95% confidence interval 3.721–8.213).

Conclusions: HCV/SMI is related to early mortality, particularly with cirrhosis. There is significantly high SMI prevalence in hospitalized HCV patients, representing a unique at-risk population. Identification during hospitalization and medical recommendations at discharge may fill the gaps.

Background: Colorectal cancer (CRC) is the third most commonly occurring cancer worldwide. There are conflicting reports on whether colonoscopies performed during the morning shift have higher adenoma detection rates.

Objectives: To investigate the differences in polyp detection rate (PDR) in colonoscopies between morning and afternoon shifts.

Methods: In a retrospective, multicenter study involving a large cohort, we analyzed all colonoscopies conducted between 2016 and 2023 across seven endoscopy departments. The PDR was compared between morning and afternoon shifts.

Results: We included 368,997 colonoscopies: 213,795 (57.9%) performed during the morning shift and 155,202 (42.1%) during the afternoon shift. Patients undergoing colonoscopies during the morning shift were more frequently female (53.8% vs. 51%, P < 0.001) and tended to be older compared to those in the afternoon shift (average age of 56.97 ± 12.6 vs. 55.6 ± 12.9, P < 0.001). Colonoscopies conducted during the morning shift exhibited a higher cecum intubation rate (CIR) (96.7% vs. 95.6%, P < 0.001). During the morning shift, higher rates of PDR (32.9% vs. 29.9%, P < 0.001) were observed. In the multivariate analysis, after adjusting for other variables, age, male sex, polyp follow-up, fecal occult blood test, morning shift, familial history of CRC, and rectal bleeding demonstrated statistically significant associations (P < 0.001) for PDR.

Conclusions: Colonoscopies during the morning shift yielded a higher PDR and CIR than those in the afternoon. To improve this rate, endoscopists working the afternoon shift must be provided with the right conditions.

Background: Uninterrupted antithrombotic treatment (ATT) during cardiac implantable electronic device (CIED) implantation increases bleeding and device-related infections (DRI) risk. The wide-awake-local-anesthesia-no-tourniquet (WALANT) technique, using large-volume local anesthesia and adrenaline, is successful in hand surgeries but its potential to mitigate bleeding risk in CIED implantations remains unknown.

Objectives: To investigate whether WALANT protocol for CIED implantations reduces clinically significant pocket hematoma in patients with a high bleeding risk or is a contraindication for interrupting ATT.

Methods: We conducted a prospective, double-blind, randomized controlled trial with CIED surgery patients on uninterrupted ATT. They received WALANT protocol (lidocaine 1% with adrenaline 1:100,000) or standard protocol (lidocaine 1%). Following implantation, patients were blindly monitored in the ward and pacemaker clinic. Patients were monitored for bleeding outcomes post-implantation.

Results: Forty-six consecutive patients (73.6 ± 9 years, 72% male) were enrolled. In the WALANT group (n=24) no intra-pocket pro-hemostatic agents were needed, compared to 45% in the control group (P = 0.0002). Postoperative pressure dressings were used in 12.5% vs. 68% (P = 0.0002). WALANT patients had smaller hematoma areas (median 3.7 cm² IQR [1–39] vs. 46 cm² [IQR 24–76], P = 0.0004) 1-day postoperative. ATT interruption occurred in 12.5% vs. 18% (P = 0.7). Superficial skin infection rates were 4% vs. 9% (P = 0.6). No DRI occurred. No WALANT-related side effects were observed.

Conclusions: WALANT protocol in CIED implantation with uninterrupted ATT reduced pro-hemostatic agents, pressure-dressing need, and hematoma size. Larger studies are needed to assess its impact on infection rates.

Acute otitis externa (AOE) is typically a bacterial infection of the external auditory canal, which is most commonly caused by Pseudomonas aeruginosa. Although AOE occurs in all age groups, it is rarely observed in children under 2 years of age [1]. Ear drainage in a neonate is a relatively uncommon finding in the neonatal intensive care unit (NICU) population. This diagnosis requires confirmation by otoscopy [2,3].

Osteomyelitis of the temporal bone, also referred to as necrotizing otitis externa, is a severe form of infection that may develop typically in diabetic or immunocompromised patients, including premature infants. Similar to simple AOE, Pseudomonas aeruginosa is the most common pathogen [4,5]. In the NICU setting it mostly causes infection in immunocompromised hosts such as premature infants [3].

Pheochromocytoma, a rare neuroendocrine tumor, classically manifests symptoms such as hypertension, palpitations, and sweating. In this report, we present an unusual case in which muscle complaints were the primary symptoms, accompanied by elevated interleukin-6 (IL-6) levels. Our findings underscore the importance of considering pheochromocytoma in the differential diagnosis of patients presenting with unexplained muscle weakness and aches, and suggests a potential link between pheochromocytoma, myositis-like symptoms, and IL-6 elevation.

Standup paddleboard surfing (SUP) is a sports activity in which a person stands upright on a surfboard and propels the board using a single paddle. It is an emerging recreational activity that is attracting public attention and gaining popularity because it promotes fitness, strength, and improved balance. In this review, we discuss the outcomes after severe cardiac events in SUP surfers. We report on six fit individuals (five males and one female, age range 41–69 years) who experienced sudden cardiac arrest (n=3) or acute myocardial infarction occurring during SUP. Cardiopulmonary resuscitation was initiated in three patients on presentation due to ventricular fibrillation. In four patients the culprit coronary artery was the left anterior descending artery treated by percutaneous coronary intervention. All patients were discharged alive. A review of the literature showed a paucity of scientific evidence to substantiate the proposed health benefits of SUP surfing. Our cluster of acute cardiac events occurring during this activity calls for heightened public awareness to better understand the physical demand required to practice SUP. There is a need for more data regarding the cardiovascular clinical aspects of this water activity, and the risks it entails.

A 71-year-old man with a history of hypertension, type 2 diabetes mellitus, and dyslipidemia was admitted for unstable angina. He subsequently underwent coronary angiography. Approximately 2 hours after successful percutaneous coronary intervention (PCI), he reported a burning and itching sensation on his buttocks. The patient had no history of atopy or drug hypersensitivity. Physical examination revealed a bilateral erythematous, warm, tender, blistering rash localized to his buttocks [Figure 1A].

Background: Ascites is a product of fluid accumulation within the peritoneal cavity. Underlying etiologies include cirrhosis, congestive heart failure (CHF), nephrotic syndrome, and malignancies. Patients with cirrhotic ascites are at increased risk for infections, especially spontaneous bacterial peritonitis (SBP), which is associated with high rates of morbidity and mortality. Ascites is diagnosed both clinically and sonographically. SBP is diagnosed via abdominal paracentesis, a relatively safe and effective procedure. However, abdominal paracentesis carries risks such as bleeding, bowel perforation, and infection.

Objectives: To identify new inflammatory markers as alternative or replacement methods for accurately evaluating patients before and after abdominal paracentesis and how these new inflammatory markers can be evaluated from a simple, inexpensive, and routinely performed blood sample.

Methods: A total of 106 patients admitted with ascites were classified into three groups based on the underlying etiology of their condition: malignant ascites (30 patients), ascites secondary to CHF (30 patients), and ascites secondary to cirrhosis (46 patients). Levels of neutrophil-lymphocyte ratio (NLR), mean platelet volume, and C-reactive protein among the study groups were examined through blood samples and subsequently compared

Results: NLR values within malignant ascites and CHF ascites were significantly higher than cirrhotic ascites (P = 0.002). In addition, among risk factors for developing ascites, significant correlations were found among the three groups in hypertension (P < 0.001), diabetes mellitus (P = 0.003), hyperlipidemia (P = 0.002), CHF (P < 0.001), and ischemic heart disease (P < 0.001) variables.

Conclusions: NLR may be a prognostic tool in patient evaluation of ascites.

Background: Solid organ transplant (SOT) recipients represent a particularly vulnerable group due to their reliance on immunosuppressive therapies. Previous studies indicated a mortality rate of 20%-30% among SOT recipients with coronavirus disease 2019 (COVID-19). With the advent of the Omicron variant in November 2021, characterized by milder symptoms and lower mortality rates in the general population, safety measures relaxed, potentially impacting vulnerable populations like SOT recipients.

Objectives: To investigate mortality and morbidity among hospitalized SOT recipients with COVID-19 infection during the Omicron wave.

Methods: A retrospective, propensity-matched cohort study conducted at the Rabin Medical Center, Israel, spanned from November 2021 to June 2023. Adult SOT recipients hospitalized with COVID-19 were compared to matched controls.

Results: Among 139 hospitalized SOT recipients and 209 controls, SOT recipients hospitalized with COVID-19 displayed higher in-hospital mortality (19% vs. 11%) and 90-day all-cause mortality (30% vs. 17%). In addition, the 90-day readmission rate was significantly higher among SOT recipients (43% vs. 31%). Multivariable analysis confirmed these trends, with SOT recipients exhibiting increased risk for mortality, readmission, invasive ventilation, and intensive care unit admission.

Conclusions: The heightened vulnerability of hospitalized SOT recipients during the Omicron wave was characterized by higher mortality and readmission rates compared to matched controls. Despite the perceived milder nature of the Omicron variant, SOT recipients remain disproportionately affected. Continued vigilance and targeted interventions are necessary for this population including vaccinations and adherence to preventive measures. Investigating this population’s outcomes through the changing COVID-19 variants is still warranted.

Crohn's disease patients undergoing anti-tumor necrosis factor (anti-TNF) therapy such as infliximab face potential risks from opportunistic infections. We introduce the unique case of a 66-year-old male Crohn's patient, previously in remission, presenting with gastrointestinal symptoms following a trip to the Czechia. Despite concerns of reactivated tuberculosis due to infliximab, his biopsies showed the presence of Mycobacterium simiae (M. simiae). Despite this, anti-TNF therapy was continued and resulted in clinical improvement. This is a case report of M. simiae in intestinal biopsies of an immunocompromised Crohn's patient is a clinical challenge. The findings suggest the benign colonization of M. simiae potentially influences future treatment considerations in similar clinical scenarios.

Background: Enterovirus meningitis (EM) is a common central nervous system (CNS) infection with a seasonal peak in summer and fall.

Objective: To describe the epidemiologic and clinical patterns of EM in children before (2017–2019 years) and during the coronavirus disease 2019 (COVID-19) pandemic (2020–2022).

Methods: This retrospective study included children (age 0–16 years) hospitalized in a pediatric department in Israel diagnosed with EM: January 2017–December 2019 and January 2020–December 2022. The seasonal peak for each period was defined as the maximal incidence in particular months. EM was diagnosed by reverse transcription polymerase chain reaction of cerebrospinal fluid (CSF) for enteroviruses.

Results: During the study period, EM was diagnosed in 134 cases (median age 5 months [1–51], 76 [57%] males); 72 during 2017–2019 and 62 during 2020–2022. The most common presentation was fever. C-reactive protein (CRP) was elevated in 57 cases (43%). CSF profile showed pleocytosis in 130 cases (97%) and elevated protein in 80 (60%). In the 2020–2022 group, fewer patients were febrile, CRP was higher, and CSF profile showed a higher glucose level compared to the 2017–2019 group. Seasonal peaks in 2017–2019 occurred June–August, and in 2020–2022 February–April.

Conclusions: The COVID-19 pandemic altered the clinical characteristics of EM and its seasonal peak. Clinicians should be aware of changes in epidemiological patterns of EM to make appropriate diagnoses in viral infection in order to avoid unnecessary antibiotic treatment.

Infant botulism is a rare and potentially fatal condition caused by intestinal colonization with Clostridium botulinum. Enteric toxin causes intestinal immobility and progressive descending paralysis due to the effect on acetylcholine release at the neuromuscular junction and other cholinergic nerve terminals, particularly in the gut [1].

We present a case of infant botulism, describe the characteristics of the disease, and focus on early diagnosis.
