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: BRCA1/BRCA2 female pathogenic sequence variant (PSV) carriers in Israel are offered semiannual cancer antigen 125 (CA125) serum level determination and transvaginal ultrasound until performing risk reducing salpingo-oophorectomy (RRSO), even with the lack of proven efficacy of these procedures in providing adequate early detection of ovarian cancer.

Objectives: To report the results of longitudinal CA125 measurements in BRCA1/BRCA2 carriers as a tool for ovarian cancer detection in a single medical center in Israel.

Methods: Asymptomatic BRCA1/BRCA2 PSV carriers attending the Meirav High Risk Clinic at Sheba Medical Center for more than 3 years were eligible. Data on specific PSV, risk reducing surgeries, and cancer diagnoses were obtained from participant records. We used chi-square and Wilcoxon-Rank tests for statistical analyses.

Results: Overall, 739 (399 BRCA1, 336 BRCA2, 4 BRCA1 + BRCA2) PSV carriers were included. Mean age at the start of follow-up was 38.96 ± 11.13 years, mean follow-up time was 7.93 ± 2.34 years, (5860.80 women/years). Most participants (490/739 [66.3%]) had stable CA125 levels (± 5 U/µl). Of participants, 61 had CA125 levels > 35 U/µl at least twice (n=42) or at least doubling of marker levels to a minimum of 20 U/µl (n=19), results that have led to further cancer defining investigations. Of these, 14 and 4 were diagnosed with breast and ovarian cancer, respectively.

Conclusions: Longitudinally stable CA125 levels were noted in most BRCA1/BRCA2 PSV carriers and elevated levels were a poor marker for ovarian cancer development.

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.

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.

We presented the emergent development of pulmonary hypertension and right ventricular impairment in a 64-year-old woman with metastatic breast cancer undergoing carboplatin–gemcitabine combination therapy. The patient's acute decompensation, characterized by dyspnea and desaturation, occurred 2 days after chemotherapy initiation. Clinical assessments revealed right ventricular dilation and systolic dysfunction, a rare manifestation not previously associated with the administered drugs, but which may be associated with cardiopulmonary toxicity of gemcitabine therapy. Prompt discontinuation of chemotherapy and initiation of diuretic therapy resulted in clinical improvement and resolution of the right ventricular dysfunction within several weeks. While a definitive causal link to gemcitabine remains inconclusive, this report highlights a potential and under-reported side effect, emphasizing the need for increased awareness and further investigation into the cardiopulmonary effects of gemcitabine.

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].

Adoration of the Shepherds is one of the favorite subjects of sacred scripture by many artists. For almost 5 centuries they have published their vision of unique moments. The largest number of paintings were completed during the 16th and 17th centuries, with approximately 160 paintings created in the 16th century and approximately 420 in the 17th century. I was able to find two publications about pathological conditions of shephards that were diagnosed by artwork analysis. They include nodular goiter in Simone Veneziano Peterzano's works (1578–1582) [1] and Down syndrome in Jacob Jordaens' artwork (1618) [2]. In one of paintings, my attention was drawn to the change in the neck of one of the members of the Holy Family, St. Joseph.

The Nazi regime occupying Europe during World War II built a series of concentration camps for those opposing the regime, political and criminal adversaries, and eventually victims of the racial, Aryan policy. It was the suggestion of Germany's elite physician to the Schutzstaffel (SS), Reichfuehrer H.H. (Heinrich Luitpold Himmler), to use the available workforce in the camps, before their eventual liquidation [2,3]. What was the outcome?

The SS medical services in the Auschwitz concentration camp functioned based on two mutually exclusive principles. On the one hand, medical care was provided for the SS staff, and on the other hand, prisoners with contagious diseases or in the terminal stages of exhaustion were eliminated.

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.
