Parenchymal mucinous cystadenoma of the kidney: a case report and literature review

Abstract Background Mucinous cystadenoma (MC) of the kidney is exceedingly rare. We found 22 similar cases in the literature. These masses are underdiagnosed due to radiologic similarities with simple renal cysts. Case presentation A 66-year-old man with a previous history of hypertension and anxiety was referred to our tertiary clinic with left flank pain. Ultrasound revealed a 60 mm-sized, complex cystic mass with irregular septa in the lower pole of the left kidney (different from last year's sonographic findings of a simple benign cyst with delicate septa). CT scan showed the same results plus calcification. Due to suspected renal cell carcinoma, a radical nephrectomy was performed. Postoperative histopathologic examination revealed a cyst lined by a single layer of columnar mucin-producing cells with small foci of pseudo-stratification, consistent with the MC’s diagnosis. The first follow-up visit showed normal blood pressure without medication and no flank pain and anxiety after a month. Conclusion It is quite challenging to distinguish the primary MC of the kidney from a simple renal cyst based on clinical and imaging findings. The radiologic features of these entities overlap significantly. Thus, complex renal cyst and renal cysts with mural nodules should be followed closely to detect malignancy earlier.

Retroperitoneal Laparoscopy

Abstract Background: Under the constraints of the increasingly tight medical environment and cost, day surgery mode has become a favorable trend and attracts attention from clinicians. Currently, there are no standards or procedures on the retroperitoneal laparoscopy for unilateral simple renal cyst decortication in day surgery mode. We attempted to investigate the feasibility and safety criteria of unilateral simple renal cyst decortication by retroperitoneal laparoscopy in the day surgery ward and to compare the advantages and the disadvantages with conventional inpatient ward mode.Methods: A total of 41 patients with unilateral simple renal cysts meeting surgical indications were enrolled in this study. To see whether patients in the day group could successfully complete the procedure and be admitted and discharged within 24 hours and to summarize the advantages and the advantages. The indexes of the operation time, time of hospitalization, postoperative complication rate, total costs of hospitalization and other indicators were compared between the two groups.Results: 41 cases of unilateral simple renal cyst decortication were completed successfully. Patients were followed up 10-12 months after surgery. The results of time of hospitalization, total costs of hospitalization and time of postoperative removal of drainage tube were statistically significant between the two groups of the day ward group and the inpatient ward group (P <0.05). Conclusions: We concluded the retroperitoneal laparoscopy for unilateral simple renal cyst decortication in patients with unilateral renal cysts was safe and feasible in day surgery mode under certain indicative criteria. The criteria included patients’ age between 40 and 80 years, no previous history of abdominal surgery, CT showing a unilateral renal cyst (Bosniak I or II), preoperative ASA assessment was I or II, no contraindications to surgery or anesthesia, postoperative team management and discharge assessment. Advantage of reducing time of hospitalization and total medical cost may relieve the situation of the shortage of medical resources.

Pancreatic heterotopia (PH) is a common, but typically small (<1 cm), incidental and asymptomatic finding; however, PH should be considered even for large and symptomatic upper gastrointestinal masses. A 27-year-old white woman presented with a 3-week history of burning epigastric pain, nausea, early satiety, and constipation. Physical examination revealed epigastric and right upper quadrant tenderness with normal laboratory workup, but imaging revealed a 5-cm, partly cystic mass arising from the gastric antrum with resulting pyloric stenosis and partial gastric outlet obstruction. Endoscopic ultrasound-guided fine needle aspiration revealed PH – an anomalous pancreatic tissue lying in a nonphysiological site. The patient ultimately underwent a resection and recovered uneventfully, with a complete pathologic examination revealing normal exocrine pancreatic tissue (PH type 2) without malignant transformation. We report a case of heterotopic pancreas manifesting as severe gastric outlet obstruction, in addition to a thorough diagnostic workup and surgical follow-up, in a young adult. Differential diagnoses and features that speak to benignity of a large, symptomatic mass lesion (PH in particular) are discussed.

Post-traumatic stress disorder (PTSD) is a prevalent mental disorder marked by psychological and behavioral changes. Currently, there is no consensus of preferred antipsychotics to be used for the treatment of PTSD. We aim to discover whether certain antipsychotics have decreased suicide risk in the PTSD population, as these patients may be at higher risk. A total of 38,807 patients were identified with a diagnosis of PTSD through the ICD9 or ICD10 codes from January 2004 to October 2019. An emulation of randomized clinical trials was conducted to compare the outcomes of suicide-related events (SREs) among PTSD patients who ever used one of eight individual antipsychotics after the diagnosis of PTSD. Exclusion criteria included patients with a history of SREs and a previous history of antipsychotic use within one year before enrollment. Eligible individuals were assigned to a treatment group according to the antipsychotic initiated and followed until stopping current treatment, switching to another same class of drugs, death, or loss to follow up. The primary outcome was to identify the frequency of SREs associated with each antipsychotic. SREs were defined as ideation, attempts, and death by suicide. Pooled logistic regression methods with the Firth option were conducted to compare two drugs for their outcomes using SAS version 9.4 (SAS Institute, Cary, NC, USA). The results were adjusted for baseline characteristics and post-baseline, time-varying confounders. A total of 5294 patients were eligible for enrollment with an average follow up of 7.86 months. A total of 157 SREs were recorded throughout this study. Lurasidone showed a statistically significant decrease in SREs when compared head to head to almost all the other antipsychotics: aripiprazole, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (p < 0.0001 and false discovery rate-adjusted p value < 0.0004). In addition, olanzapine was associated with higher SREs than quetiapine and risperidone, and ziprasidone was associated with higher SREs than risperidone. The results of this study suggest that certain antipsychotics may put individuals within the PTSD population at an increased risk of SREs, and that careful consideration may need to be taken when prescribed.

Solitary renal cysts are relatively common. The occurrence of transitional cell carcinoma (TCC) in a renal cyst is rare. We present the case of a 59-year-old man with a medical history of viral hepatitis B. During a workup for his hepatitis, a computed tomography scan revealed a large cystic tumour in the upper region of the left kidney. A radical left nephrectomy was performed. Microscopic examination of the cystic tumour revealed a grade 2 TCC. The cyst was lined by transitional epithelium. This is a case of a TCC growing within a renal calyceal cyst.

We report the case of a 38-year-old male with a previous history of severe cranial trauma and subsequent large subdural and subarachnoid hemorrhage on whom an emergent hematoma evacuation was performed with a good outcome and follow-up. Despite a good clinical evolution, the patient experienced a further intracranial hematoma 18 years after the trauma, with severe aphasia and mild right hemiparesis. After complete etiological study, two cranial pseudoaneurysms were observed in the cerebral angiography. Endovascular treatment was successfully completed, achieving full embolization without complications. No rebleeding was detected during follow-up. The patient had a good clinical outcome at 3 months and achieved complete recovery. Cranial pseudoaneurysm rupture is a rare cause of intracerebral hemorrhage, especially if the trauma occurs years before the bleeding.

Purpose: To report a case of paradoxical emboli to multiple visceral vessels treated with both mechanical (AngioJet device) and pharmacological (urokinase) thrombolysis. Methods and Results: A 72-year-old man presented with a 48-hour history of symptomatic right renal ischemia, which was treated with heparinization. Five days later, an abrupt creatinine elevation prompted arteriography, which demonstrated thromboembolism of the superior mesenteric artery (SMA) and both renal arteries. The AngioJet aspiration device was employed to successfully remove the clot from the SMA; urokinase infusion restored flow to the left kidney. At the 16-month follow-up evaluation, the patient was normotensive without medication and had a stable creatinine (1.4 mg/dL). Conclusions: Because of its speed and minimal morbidity, the AngioJet device may be an attractive alternative to surgical embolectomy or pharmacological thrombolysis in highly selected cases of acute visceral artery thromboembolism.

SummaryThe difficulties in measuring suicidal intent in cases of self-injury are discussed, and a scale is described to measure this intent. This scale has been used in 500 cases of self-injury. It is practical and reliable. Results show that the scores derived from it are closely related to the similar Beck Scale; they are also related to age, sex, social isolation, method of self-injury, previous history of self-injury or of psychiatric treatment, physical health at the time of self-injury and alcohol abuse. These results are discussed with particular reference to suicide prediction and the future validation of the scale by long-term follow-up.

Abstract Essential thrombocythemia (ET) is a chronic myeloproliferative disorder characterized by peripheral thrombocytosis and abnormal proliferation of megakariocytes in the bone marrow. Even thought thrombosis is frequently associated to ET, the risk factors of this clinical complication are still controversial. The aim of this retrospective, single institution study was to investigate clinical and laboratory characteristics associated with the occurrence of thrombotic events, with the purpose of identifying subgroups of patients who could benefit from antiaggregant and/or cytostatic treatment. 306 consecutive ET patients (109 men and 197 females, median age 58 yr) diagnosed between January 1979 and December 2002 were included in the study. At the time of analysis, 196 patients were still alive with a median follow up of 96 months. The following variables were investigated for the association with thrombotic complications: age, platelet count, previous history of thrombotic events, time from diagnosis, treatment with antiaggregant/cytostatic drugs, and cardiovascular risk factors such as arterial hypertension, obesity, hypercolesterolemia, diabetes, cigarette smoking. At the time of last follow up, 46 patients (15%) experienced at least one thrombotic event. The occurrence of thrombotic events was observed in 26/64 (40.6%) patients with previous history of thrombosis and in 20/242 (8.3%) patients with no previous history of thrombosis (p<0.0001 Fisher’s exact test, odd ratio 7.6). A significant difference between the two groups of patients was also confirmed when Kaplan Meier estimates of thrombosis-free survival were compared by log-rank test (p<0.0001). By logistic regression, platelet number at diagnosis did not associate with occurrence of thrombosis in the whole patient population. When patients without previous history of thrombosis were stratified according to the number of cardiovascular risk factors (none vs one vs more than one), a significant correlation with occurrence of thrombotic events was observed (Mantel-Haenszel Chi-square 5.47, p<0.05). This study confirms that history of thrombosis is strongly related with risk of further thrombotic events in patients with ET, whereas platelet number at diagnosis does not seem to represent a prognostic factor. In patients with no previous history of thrombosis, the presence of other cardiovascular risk factors has to be taken into account when establishing the therapeutic approach.

Abstract Pleural effusions (PE) are a relatively common side effect of dasatinib (an oral multi-targeted kinase inhibitor) and have been reported in 20–30% of CML patients. The underlying mechanism is unclear but may be related to inhibition of the PDGFR gene. We report a series of 43 patients, who received dasatinib while in first chronic phase, after imatinib resistance (n=31) or intolerance (n=12). Twenty two patients had previously received interferon. Patients were treated with dasatinib 70 mg twice daily. The median follow-up was 149 days (range 21–730). Of the 43 patients, 14 developed PE at a median of 150 days (range 21–698) after starting dasatinib. The dasatinib was interrupted in all cases and not resumed until the PE had resolved completely, which occurred in all cases. Diuretics were administered in some cases. The median duration of discontinuation was 14 days (range 7–65). In 8 of the 14 patients the drug was re-started at reduced dose following the first episode of PE. PE recurred in 4 patients (3 patients had two and 1 patient 5 episodes). The dose was further reduced in these cases and eventually abandoned in 2 patients. We performed univariate and multivariate analysis to identify prognostic factors for the development of PE. Significant variables were: prior skin rash on imatinib therapy, [21% non PE vs 57% PE (p=0.035)], skin rash on dasatinib [(before the development of PE vs any time during the follow up) 4% non PE vs 47% PE (p=0.002)], and previous history of autoimmune disease, [non PE 7% vs 50% PE (p=0.006)]. The documented autoimmune diseases were: hyperthyroidism (n=1), hypothyroidism (n=3), systemic lupus erythematosus (n=1), Sweets syndrome (n=1) and auto-immune hepatitis (n=1). We did not find correlation between the previous history of autoimmune disorders and having been treated with interferon. The dose of dasatinib prior to the onset of PE was compared with the dose in patients who did not develop PE at 6 months; patients still receiving 70 mg twice a day were more likely to develop PE than those for whom the dose had been reduced, with a relative risk (RR) for the development of PE of 4.7 (95CI 1.2–18.4, p=0.02). The only variables that were predictive in the multivariate analysis were a history of autoimmune disease and the dose of dasatinib [RR 13 (95CI 1.6–103) and RR 7.4 (95CI 1.2–44.3) respectively]. Interestingly the presence of generalised fluid retention was not found to be significant (p=0.54) nor the previous therapy with interferon (p=1.0). Our results are in agreement with recent reports which suggest that dasatinib-induced PE does not correlate with generalised fluid retention and may be mediated by an immune mechanism. Moreover dasatinib-induced PE are usually exudates and are believed to respond to steroids. In summary in this series PE occurred more frequently in patients with a previous history of autoimmunity and imatinib-related dermatological side effects; both observations support the notion that PE secondary to dasatinib therapy may have an auto-immune pathogenesis.

5055 Background: The use of infertility drugs (ID) in infertile patients treated conservatively for ovarian malignancies remains theoretically contraindicated. Few recent case reports seem to suggest that ID could be used in patients treated for a borderline ovarian tumors (BOT). The aim of this multicenter retrospective study was to report the outcomes of the largest series of patients with a previous history of a BOT who underwent the use of ID. Methods: A multicenter retrospective study was conducted among centers which participate in the French National Register on In Vitro Fertilization registry to evaluate the outcomes of patients with a previous history of a BOT treated with ID. Four criteria were defined to select cases: 1. Histologic confirmation of BOT, 2. The use of a conservative surgery, 3. The use of ID and 4. A follow-up ≥ 12 months after the end of infertility treatment. Results: Thirty cases fulfilled inclusion criteria. Infertility therapy began in November 1989. Disease stages were: I (n = 20), II /III with noninvasive implants (n = 8) and unknown in 2 cases. The mean number of cycles of ovarian induction per patient was 2.6 (range,1–10). After a median follow-up of 42 months after infertility treatment, 4 recurrences were observed (all of them were borderline tumors on a remaining ovary treated by surgery alone). All patients are currently disease-free. Thirteen patients have since become pregnant. The median interval between treatment of the BOT and the use of ID is shorter in patients who relapsed compared to patients who did not (5 versus 29 months; p=.07). Conclusions: These results suggest that infertility drugs could be safely used in patients who experience infertility after conservative management of an early-stage BOT. A minimal interval should be respected between treatment of the ovarian tumor and the use of infertility drugs in order to decrease the risk of recurrence. No significant financial relationships to disclose.
