Isolated Ruptured Inter‐Atrial Septal Cystic Echinococcosis during Pregnancy

Herein, we present a case of asymptomatic isolated cardiac cystic echinococcosis localized entirely to the inter‐atrial septum in a pregnant woman. The patient underwent successful surgery. Cardiac cystic echinococcosis is rarely seen in pregnancy. A high index of suspicion is necessary for the diagnosis of a cardiac cyst hydatid. The treatment of cardiac cyst hydatid is surgical and should not be delayed during pregnancy. Early surgery might prevent septic embolization and cardiac life‐threatening complications and save the lives of both mother and baby as in the present case.     

Successful treatment of massive thrombosis in different locations with prolonged thrombolytic therapy: A life-saving intervention

Venous thrombosis is recognized as one of the most important complications of nephrotic syndrome (NS). In patients with NS, venous thrombosis may develop in the renal veins, the deep veins of the lower limb, and the inferior vena cava. Here, we describe a case report of an NS patient with multiple venous thrombosis in the right renal vein, the left iliac vein, the vena cava inferior, the right atrium, and the pulmonary arteries. Moreover, we describe the successful treatment of multiple venous thrombosis with prolonged thrombolytic treatment in spite of an increased risk of bleeding due to renal biopsy.     

Comparison of Ho:YAG laser and pneumatic lithotripsy in the treatment of impacted ureteral stones: An analysis of risk factors

The aim was to compare pneumatic and holmium:yttrium-aluminum-garnet laser in the treatment of impacted ureteral stones with different locations and to identify the risk factors for complications. Between March 2005 and November 2012, a total of 230 patients underwent ureteroscopic lithotripsy for impacted stones. Of the patients, 117 had pneumatic and 113 had laser lithotripsy for the fragmentation of the stones. Treatment outcomes based on evidence of being stone free were evaluated. Preoperative, operative, and postoperative follow-up findings were analyzed and compared. There was a difference between the two groups according to overall stone clearance rate (93.8% vs. 80.3%, p = 0.002). There was no statistically significant difference for distal location between the laser and pneumatic groups (96.8% vs. 91.7%, p = 0.288). For 10 patients with intrarenally migrated stones who were managed with flexible ureterorenoscopy in the same session, laser lithotripsy was more successful than pneumatic for proximal ureteral stone (94.4% vs. 67.9%, p = 0.007). The overall complication rate was 26.1%. There was no statistically significant difference between the two groups (29% vs. 23%, p = 0.296). Multivariate logistic regression analysis revealed that the proximal location was a statistically significant parameter for the occurrence of complications in both groups (p = 0.001 for PL, p = 0.004 for laser). The pneumatic and holmium:yttrium-aluminum-garnet laser lithotripsy are effective in the treatment of distal impacted stones. Both treatments with semirigid ureteroscopy are acceptable for proximal impacted ureteral stones, but holmium laser lithotripsy has an advantage of use with flexible ureteroscope for intrarenally migrated stone.     

Comparison of the morphokinetic parameters of embryos according to ovarian reserve in IVF cycles

The aim of this study is to evaluate the impact of ovarian reserve and age of women on early morphokinetic parameters of embryos with a time-lapse monitoring system. In total, 197 infertile couples with poor ovarian reserve (Group 1, n?=?41), normal ovarian reserve (Group 2, n?=?59), or polycystic ovaries (Group 3, n?=?97) were included. The time from insemination to the following events were analyzed: pronuclear fading (Pnf) and cleavage to 2, 3, 4 and 5 cells. The optimal ranges for morphokinetic parameters of t5, s2 and cc2 in each group were also evaluated. In total, 1144 embryos were evaluated. Morphokinetic parameters did not differ statistically between the groups. Data were analyzed according to different age groups (20–30, 30–40,?>40). The morphokinetic parameters did not differ statistically in Group 1 and 3. In Group 2, the times from insemination to tPnf, t2, t3, t4 were significantly shorter in the younger age group than the older age group (p?相似文献   

Rare causes of gastrointestinal hemorrhage in infancy

Gastrointestinal hemorrhage in children is a critical condition that demands quick and effective management. The differential diagnosis of gastrointestinal hemorrhage is wide. Heterotopic pancreas is a rare congenital anomaly and usually discovered incidentally. It is generally asymptomatic, but symptoms may occur when complicated by inflammation, bleeding, obstruction or malign transformation. Heterotopic pancreas may present throughout the gastrointestinal tract, but it is most commonly found in the stomach, duodenum and proximal jejunum. Juvenile polyps are common during childhood and present most often with painless rectal hemorrhage. They remain the most common colonic polyps in children. Colonoscopic polypectomy is the most effective procedure in the treatment of juvenile polyps. In this study, we describe rare causes of gastrointestinal system hemorrhage in infancy and discuss some diagnostic and therapeutic approaches.

A novel PSEN2 p.Ser175Phe variant in a family with Alzheimer’s disease

Neurological Sciences - Alzheimer’s disease (AD) can be either sporadic or familial, and familial forms of AD accounts for only 5% of the cases. So far, autosomal dominantly inherited...
