Spilled Gallstones: the Source of an Enigma

Spillage of gallstones may occur in the course of laparoscopic cholecystectomy. The incidence of this mishap and its consequences are variable. Ignored by many surgeons, stone spillage may be the source of significant morbidity many years after surgery. In this report, we describe the clinical course of a patient who presented with upper abdominal pain and swelling. The past history was positive for laparoscopic cholecystectomy 15 years earlier. After excision, the swelling was found to be a pseudocyst formed around spilled gallstones during a previous cholecystectomy. Apart from postoperative wound infection, the patient recovered well and remains so. Here, we discuss the problem and provide suggestions for spillage prevention and stone retrieval once spillage occurs.

Psychiatric comorbidities in patients with inflammatory bowel disease

Background

Psychiatric comorbidities are associated with inflammatory bowel disease (IBD). We conducted an observational study to evaluate the prevalence of depression and anxiety in patients with IBD.

Methods

Seventy consecutive consenting patients with IBD (62 ulcerative colitis [UC], 8 Crohn’s disease [CD]; 40 males, mean age [SD] 36.2 [11.3] years) and 100 healthy volunteers (44 males, age 31.22 [SD] [10.5] years) as controls were enrolled. All participants were directed to take self-assessment tests, Patient Health Questionnaire -9 (PHQ-9) and Symptom Checklist Anxiety Scale (SCL-A20). Participants having a score ≥ 10 on PHQ-9, or ≥ 29 on SCL-A20 were administered the Hamilton Depression Rating Scale (HAM-D) or Hamilton Anxiety (HAM-A) scales, respectively. The severity of depression and anxiety was graded with HAM-D and HAM-A scales, respectively. The protocol was approved by the Institutional Ethics Committee.

Results

The prevalence of depression (34.3% vs. 5%, p?<?0.0001, OR 9.7) and anxiety (18.6% vs. 2%, p?=?0.0002, OR 11.17) was higher in patients with IBD as compared to controls. The severity of depression was higher in patients compared to controls (mean rank 17 vs. 7, p?=?0.04). The prevalence of depression was not different between UC and CD; all IBD patients with anxiety had UC. The mean duration of disease and history of corticosteroid treatment or surgery for IBD were not associated with the presence of depression or anxiety. Patients with severe CD (Crohn’s disease activity index, CDAI?>?450) had more severe depression. The severity of UC did not correlate with severity of anxiety or depression in UC.

Conclusions

Anxiety and depression are more prevalent in IBD patients as compared to healthy individuals.

     

Efficacy,Safety and Characteristics of the Amplatzer Vascular Plug II and IV Utilization for Various Percutaneous Occlusions in Children under 10 Years

Objectives: We aim to describe the efficacy, safety, and characteristics of the Amplatzer Vascular Plug (AVP) II and IV “off-label” use for multiple cardiovascular occlusions in children under 10 years. Methods: Observational retrospective multicenter (2007–2020, 6 centers) review of paediatric procedures using AVP II or IV. Results: A total of 125 children (49.6% aged ≤ 1 year, 147 lesions) underwent 136 successive procedures (success rate: 98.5%) using 169 devices (109 AVP IV, 60 AVP II). The mean device diameter was 7.7 ± 3.2 mm (4–20 mm). The median AVP size to vessel diameter ratio was 1.3 (0–2). The median age and weight at implantation were 1.0 year (0.01–9.98) and 8.4 kg (1–69). Procedures were heterogeneous (55 patent ductus arteriosus (PDA), 28 collaterals, 18 sequestrations, 22 arteriovenous/veinovenous/coronary fistulas, 6 vertical veins, 6 conduits, 5 ventricular septal defects, 7 miscellaneous). Day 1 and 6-month occlusion rates were respectively 94.8% and 98.5%. Major adverse events (MAE) occurred in 5.2% of cases (no procedure-related deaths), and more frequently in weight ≤ 5 kg (p = 0.01), younger patients (p = 0.03) during PDA closure (p = 0.02) of tubular types (p = 0.02) using larger devices (p = 0.03) and AVP II (p = 0.003). Independent predictor of MAE risk was a higher AVP diameter to patient weight ratio (Odds-ratio: 2.33, 95% confidence interval 1.31–4.13, p = 0.004, optimal cut off: 1.45). Conclusions: Both AVPs are safe and effective for percutaneous occlusions in children under 10. Such devices represent an alternative “off label” use for well selected paediatric patients.

In vitro and in vivo activities of C-terminally truncated PTH peptides reveal a disconnect between cAMP signaling and functional activity

There is considerable evidence implicating the cAMP-signaling pathway in the anabolic action of PTH; and to date, all PTH and PTHrp peptides that stimulate cyclic AMP are active in animal models of osteogenesis. We have tested two C-terminally truncated peptides, PTH(1–29) and a modified PTH(1–21) (MPTH(1–21)), in in vitro and in vivo assays of PTH action. Each of the C-terminally truncated peptides was of low nanomolar potency in assays of receptor binding and cAMP stimulation. However, when we tested these peptides for functional response in Saos-2 cells stably transfected with a cyclic AMP response element (CRE) reporter, the C-terminally truncated peptides were two to four times less potent than would be expected from their binding and cAMP-stimulating properties. Furthermore, PTH(1–29), although active, was approximately 20-fold less potent than PTH(1–34) in a rat model of osteogenesis while MPTH(1–21) was inactive. The relative lack of activity of these peptides in vivo suggests that while activation of the cAMP pathway may be important for the anabolic effect of PTH fragments, it is not, of itself, predictive of their in vivo activity.
