Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

Management and Follow-Up of Pediatric Asymptomatic Testicular Microlithiasis: Are We Doing It Well?

PURPOSE: To define timing and methods for a balanced follow-up of testicular microlithiasis (TM) in pediatric age.MATERIALS AND METHODS: We retrospectively reviewed medical records of 21 pediatric asymptomatic patients (42 testicular units) diagnosed with TM and without associated risk factors. Microliths were found bilaterally on ultrasonography in all the patients. Distribution of microliths (focal or diffuse) inside the parenchyma was evaluated as well as its eventual variation over time. Every six months, each patient underwent clinical and ultrasonography evaluation, as well as serum chemistry markers (α-fetoprotein and β-human chorionic gonadotropin) measurement to detect potential malignancy. In the interval between the follow-ups, parents and/or patients themselves were asked to control eventual enlargement of the gonads or scrotal swelling. Testicular biopsy was not performed in any of our subjects.RESULTS: Of 21 patients, 6 had unilateral undescended testis, 4 varicocele, and 1 patent processusvaginalis with scrotal swelling while 10 patients did not show associated anomalies. The distribution pattern of microliths on ultrasonography remained unchanged in all follow-ups in every patient, showing a predominance of diffuse pattern in the undescended testis series. Tumor markers remained within normal limits. In no subject, we observed a shift toward a malignant condition.CONCLUSION: In the pediatric population with an incidentally diagnosed TM and without any associated risk factor, a slight follow-up is suggested, consisting of clinical evaluation every 6 months, without any justifiable recommendation to perform a testis biopsy and a measurement of serum tumor markers

… And if this was a Zinner's syndrome?

A two year-old male was seen to our Emergency Department for acute abdominal pain, urinary retention and worsening constipation. A first level diagnostic imaging showed a pelvic cystic mass between bladder and rectum. Left kidney was absent. Further workup with MRI and endoscopy demonstrated the cyst to be of urogenital origin. Rapid increase in size and clinical symptoms prompted surgery. Pathology and surgical specimen showed the mass to be a left seminal vesicle cyst secondary to a malformation of the eiaculatory duct and embriologically related to ipsilateral renal agenesis. Such findings were consistent with the diagnosis of Zinner's syndrome (a clinical triad consisting of seminal vesicle cyst, ejaculatory duct obstruction and ipsilateral renal agenesis). Since the symptoms related to the seminal vesicle cyst coincide with the onset of a sexually active life, the majority of cases are generally observed and treated in the second and third decade. To our knowledge, this is the first case description in pediatric age

Prenatal hydrocolpos in a male

Authors report on a case of prenatal diagnosis of hydrocolpos in a genetically male subject. Postnatal sonography and endoscopy confirmed the presence of a urogenital sinus and a vaginal cavity. Despite these findings, karyotype unexpectedly revealed a 46 XY, SRY positive, male subject. Even in the presence of an established diagnosis of fetal hydrocolpos, caution should be taken before conveying information to the parents about the fetal sex. Fetal karyotyping needs to be obtained whenever possible

Antiretroviral neuropenetration scores better correlate with cognitive performance of HIV-infected patients after accounting for drug susceptibility

The aim of the study was to explore how viral resistance and antiretroviral central nervous system (CNS) penetration could impact on cognitive performance of HIV-infected patients

Saccharomyces cerevisiae-associated diarrhea in an immunocompetent patient with ulcerative colitis

Infectious diarrhea is common in cases of ulcerative colitis (UC), caused by resistance to treatment. In particular, it has been associated with cytomegalovirus or infection has rarely been observed in human beings, but has never been seen in immunocompetent patients. We report a case of intestinal infection presenting as acute diarrhea in a patient with a 10-year history of UC who was never treated with immunosuppressants

Real time endoscopic imaging of oxyradical generation in pig stomach during ischemia-reperfusion.

BACKGROUND: Oxygen-free radicals generation is considered to be a major cause of gastric injury during reperfusion. Chemiluminescence has been used to assess real-time free radical release on the surface of isolated organs. AIMS: To evaluate the combined use of chemiluminescence and gastroendoscopy techniques and to assess the real-time production of free radicals during ischemic damage of the gastric wall in an animal model. PATIENTS AND METHODS: For the experiment, an optical junction was set up between a fibroendoscope and a luminograph apparatus. Three pigs were submitted to gastrofibroendoscopy before, during and after 30 min of clamping of the coeliac artery. Under basal conditions, at the end of the ischemic phase and at the beginning of reperfusion, 1 mM of lucigenin, a specific superoxide enhancer, was injected in the left gastric artery of the animal. The endoscopic live images and chemiluminescence emission were recorded and successively superimposed to measure rate and spatial distribution of photon emission (photons/s). RESULTS: Free radical production was not observed under basal conditions or during the ischemic phase, but significantly increased during reperfusion reaching a maximum peak after 15 min (0.6+/-0.2 photons x 10(5)/s) and decreased progressively thereafter. The superimposition of live and chemiluminescence images allowed the determination of the regional production rate and distribution of photons. CONCLUSIONS: Preliminary observations, in an animal model, on an innovative imaging system which allows the visualization of rate and spatial distribution of reactive oxygen species formation are presented. This new endoscopic technique could be useful for the assessment of oxidative gastric mucosal injury in several gastric diseases; however, further studies remain necessary to determine the applicability of this technique in humans

An apparent idiopathic case of relapsing acute pancreatitis

We describe a case of relapsing acute pancreatitis apparently idiopathic in a 55-year-old man. The patient did not smoke and was a modest and irregular drinker of wine. Endoscopic retrograde cholangiopancreatography showed an initial dilatation of secondary ducts like a chronic pancreatitis of class I of Cremer. Ultrasound and computed tomography resulted negative for pancreatic lesions. In the follow-up however, magnetic resonance cholangiopancreatography detected the presence of an intraductal mucin-hypersecreting neoplasm, a duct-ectatic mucinous cystic tumor of the pancreas, in the uncinate process. This is a benign lesion clearly recognized nowadays by magnetic resonance cholangiopancreatography, because this radiological technique shows the grape-like clusters of cystic lesions in secondary ducts communicating with the main duct on the same plane. The radiological picture above excludes a malignant lesion and a biopsy specimen is not required. Furthermore, an intraductal mucin-hypersecreting neoplasm of the pancreas does not require an immediate surgical resection because of its slow evolution and can be followed-up. Conversely cystoadenocarcinoma spreads in peripheral ducts and does not communicate with the Wirsung duct. It requires both surgical resection and a biopsy specimen for histological diagnosis. In the last episode of acute pancreatitis, a sphincterotomy was performed at endoscopic retrograde cholangiopancreatography and our patient had no more pain for one year

Verbal list learning and memory profiles in HIV-infected adults, Alzheimer’s disease, and Parkinson’s disease: An evaluation of the “cortical hypothesis” of NeuroAIDS

<p>HIV+ population is getting older because of progress in treatments. Yet, there are concerns that Older HIV+ individuals (OHIV+) may be more vulnerable for developing a “cortical” dementia such as Alzheimer Disease (AD). Our aim was to explore the hypothesis that the cognitive deficit extends to ‘‘cortical’’ functions in OHIV+ by comparing serial position effects (SPE) in different groups of participants affected by “cortical” or “subcortical” damage. We enrolled a total of 122 subjects: 22 OHIV+ (≥60 years of age), 31 Younger HIV+ (YHIV+) (<60 years of age), 18 participants with AD, 23 subjects with Parkinson Disease (PD), and 28 healthy subjects. All subjects performed verbal learning tasks (VLT) to explore SPE. Factorial analysis of covariance showed a significant effect of “group” (<i>p</i> < 0.001) and “task” (Primacy vs Recency) (<i>p</i> < 0.001), but no significant group*task (<i>p</i> = 0.257) interaction. Compared with healthy subjects (<i>p</i> = 0.003), AD had the most severe reduction of Primacy, confirming a primary “encoding deficit,” while PD confirmed a “frontal pattern.” OHIV+ showed a memory profile similar to that of PD with a worsening of the cognitive performance in comparison with YHIV+. In conclusion, we did not confirm the “cortical” hypothesis in OHIV+, at least in terms of learning and memory functions.</p
