Noncirrhotic portal hypertension (NCPH) is a rare cause of portal hypertension with varied etiologies. We present two cases of painful splenomegaly secondary to NCPH successfully treated with partial splenic artery embolization (PSE). Despite limited literature on PSE's efficacy for NCPH-related painful splenomegaly, our cases demonstrate significant pain relief and reduction in opiate dependence postprocedure. Imaging revealed substantial decreases in spleen size without major complications. PSE emerges as a promising therapeutic option for NCPH-related painful splenomegaly, offering improved quality of life and reduced reliance on analgesics.

To compare clinician documentation of sepsis for infective presentations in the ED against a formal sepsis pathway in the ED and to assess appropriateness of the initial parenteral antibiotic prescription for adult patients in ED. A retrospective, clinical audit of adult patients who received at least one parenteral antibiotic in ED over a 10-week period in 2018. Documented initial clinical impression was compared with an approved sepsis pathway. Antibiotic appropriateness was assessed using National Antimicrobial Prescribing Survey definitions. Assessment was carried out by an infectious diseases pharmacist, with input from an infectious diseases physician. Two hundred and nineteen infective presentations were included in the analysis. There was a discordance between the initial documented clinical impression compared with the classification when a sepsis pathway was applied. An initial documented clinical impression of sepsis and septic shock was present in 38 (60.3%) of the presentations compared to 63 presentations when a formal sepsis pathway was applied as a screening tool. There was a significant difference in the proportion of patients in each diagnostic group (infection, sepsis and septic shock) according to documented clinical impression versus sepsis pathway classification (P = 0.0002). There were 386 prescriptions for antibiotics as part of the initial management. Antibiotic appropriateness for the initial prescription was assessed as 63.7% appropriate, 27.2% inappropriate and 9.1% not assessable. Our observations demonstrate that use of a formal sepsis pathway may improve the screening and early diagnosis of sepsis and septic shock and that there is a need for antibiotic prescribing guidance in the ED.

The current framework for testing and regulating vaccines was established before the realization that vaccines, in addition to their effect against the vaccine-specific disease, may also have “non-specific effects” affecting the risk of unrelated diseases. Accumulating evidence from epidemiological studies shows that vaccines in some situations can affect all-cause mortality and morbidity in ways that are not explained by the prevention of the vaccine-targeted disease. Live attenuated vaccines have sometimes been associated with decreases in mortality and morbidity that are greater than anticipated. In contrast, some non-live vaccines have in certain contexts been associated with increases in all-cause mortality and morbidity. The non-specific effects are often greater for female than male individuals. Immunological studies have provided several mechanisms that explain how vaccines might modulate the immune response to unrelated pathogens, such as through trained innate immunity, emergency granulopoiesis, and heterologous T-cell immunity. These insights suggest that the framework for the testing, approving, and regulating vaccines needs to be updated to accommodate non-specific effects. Currently, non-specific effects are not routinely captured in phase I–III clinical trials or in the post-licensure safety surveillance. For instance, an infection with Streptococcus pneumoniae occurring months after a diphtheria-tetanus-pertussis vaccination would not be considered an effect of the vaccination, although evidence indicates it might well be for female individuals. Here, as a starting point for discussion, we propose a new framework that considers the non-specific effects of vaccines in both phase III trials and post-licensure.

To investigate the prevalence and format of medical morning handover report (MMHR) in Australian hospitals. Questionnaire survey faxed to 76 Australian hospitals accredited for basic physician training by the Royal Australasian College of Physicians (RACP). The survey was conducted in 2005. Use of MMHR; structure and format of meetings. 53 of 76 (70%) hospitals responded. However, some data (1.7% of possible responses) were missing or illegible. Prevalence of the use of MMHR in respondent hospitals was 58% (31/53). Analysing the data by RACP accreditation level, 18/24 Level 3 hospitals (75%) conducted MMHR compared with 5/9 Level 2 hospitals (56%) and 7/18 Level 1 hospitals (39%) (odds ratio [OR] for trend, 2.17; 95% CI, 1.12-4.23; P = 0.023). 44 of 53 respondents reported their Rural, Remote and Metropolitan Areas (RRMA) classification. MMHR is less likely to be held in hospitals in regions classified as RRMA 2-4 (8/21 [38%]) than those in capital cities (RRMA 1) (16/23 [70%]) (OR, 0.27; 95% CI, 0.08-0.95; P = 0.042). In 62% of hospitals, MMHR was chaired by a consultant, and at most hospitals (23/31 [74%]), meetings were 15-30 minutes long. In spite of RACP accreditation requirements, the use of MMHR in Australian hospitals accredited for basic physician training is low.

A detailed analyses of gastric cancer incidence and mortality rates in Tasmania was done using fifteen years (1978-1992) of population based Tasmanian Cancer Registry data. The age standardised incidence rates for the period were 12.5 per 100,000 men (95% CI 11.4-13.6) and 5.2 per 100,000 women (95% CI 4.6-5.8). The age standardised mortality rates were 10.6 per 100,000 men (95% CI 9.6-11.6) and 4.1 per 100,000 women (95% CI 3.5-4.6). Male:Female ratio of mortality rates was 2.6. Gastric cancer mortality rates have now significantly declined among males (p = .03) and females (p = .02). No significant decline was observed for incidence rates among males (p = .1) and females (p = .3). For cases overall, there was a preponderance of intestinal type of gastric cancer (76.5%). No significant trend over time was observed in the mean rate of occurrence of intestinal or diffuse type of gastric cancer. The ratio of intestinal: diffuse was 6.5 for all ages. Among males, a significant (p = .03) upward trend in the incidence was observed for proximal tumours, while no such trend (p = .07) was observed among women. A significant decline in incidence of distal tumours was observed for males (p = .000) and females (p.007). Male:Female ratio for proximal tumour was 4.7:1. The results suggests that Tasmanians may have been a population at high risk of gastric cancer.
