Severe hypernatremia in hyperglycemic conditions; managing it effectively: A case report.

BACKGROUND: Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are common acute complications of diabetes mellitus with a high risk of mortality. When combined with hypernatremia, the complications can be even worse. Hypernatremia is a rarely associated with DKA and HHS as both are usually accompanied by normal sodium or hyponatremia. As a result, a structured and systematic treatment approach is critical. We discuss the therapeutic approach and implications of this uncommon presentation. CASE SUMMARY: A 62-year-old man with no known past medical history presented to emergency department with altered mental status. Initial work up in emergency room showed severe hyperglycemia with a glucose level of 1093 mg/dL and severe hypernatremia with a serum sodium level of 169 mEq/L. He was admitted to the intensive care unit (ICU) and was started on insulin drip as per DKA protocol. Within 12 h of ICU admission, blood sugar was 300 mg/dL. But his mental status didn't show much improvement. He was dehydrated and had a corrected serum sodium level of > 190 mEq/L. As a result, dextrose 5% in water and ringer's lactate were started. He was also given free water via an nasogastric (NG) tube and IV Desmopressin to improve his free water deficit, which improved his serum sodium to 140 mEq/L. CONCLUSION: The combination of DKA, HHS and hypernatremia is rare and extremely challenging to manage, but the most challenging part of this condition is selecting the correct type of fluids to treat these conditions. Our case illustrates that desmopressin and free water administration via the NG route can be helpful in this situation.

Socket shield technique and delayed implant placement in maxilla: a series of five case reports.

BACKGROUND: Tooth extraction is often followed by remodeling of hard and soft tissues, while socket shield technique has been proposed to prevent or minimize this remodeling. Socket shield accompanied with delayed implant placement is a novel technique that could be used when delayed implantation is selected; however, more scientific based evidence is required to recommend this technique as everyday clinical practice. Thus, the aim of this case series was to assess the clinical, radiographic, and esthetic outcomes of the delayed placed implants associated with previously prepared socket shield at 3-15 months follow-up after loading. The stability of the shield and the depth of soft tissue penetration palatal to the shield at reentry of 3-6 months were also assessed. CASES PRESENTATION: Five case reports of socket shield with delayed implant placement were described in the study. The facial shields were prepared and simultaneously the sockets were grafted with mineralized allograft particles, then the implants were placed 3-6 months later. Periodontal probe was used to measure the depth of soft tissue penetration palatal to the shield at reentry. Clinical indices of bleeding index, plaque index, and probing depths were recorded. Radiographic evaluation to record the amount of marginal bone loss post-loading, esthetic assessment using modified pink esthetic score, and patient assessed outcomes were also evaluated at 3-15 months follow-up after loading. At 3-6 months reentry, all shields were stable with maintenance of the facial bone and with extreme hard tissue formation in the sockets. All five implants were successful and functional without any pain or inflammation, with optimal soft tissue health and esthetics, and with minimal radiographic marginal bone loss at the last follow-up visit (3-15 months after loading). CONCLUSIONS: Within the limits of this study, socket shield technique with delayed implant placement could be a predictable minimally invasive option for cases requiring delayed implant placement; however, a long-term well-designed clinical proof is warranted.

Giant Hepatic Hemangioma Regressed Significantly Without Surgical Management: A Case Report and Literature Review.

Hepatic hemangioma (HH) is a congenital vascular anomaly comprising networks of abnormal blood and/or lymphatic vessels with endothelial cell proliferation. Their pathophysiology is not fully understood, and no specific drug is available to treat them. Conservative management, which limits observation, is preferred for most patients. A HH larger than 4 cm is considered a giant HH that may be treated using surgery ranging from embolization to hepatic resection or liver transplantation. Here, we describe a case with multiple and giant HHs that regressed significantly after treatment with azithromycin (AZM). A systematic literature review of HH and the effects of AZM on angiogenesis was then conducted.

Standardized fractal bench test evaluation of coronary stents: Performances in bifurcation lesions treated by the re-proximal optimization technique.

BACKGROUND: Bifurcation lesions in coronary arteries are complex to treat with coronary stents, which are not designed for that purpose and can be unproperly deployed. Moreover, devices are constantly evolving, and so are angioplasty techniques. OBJECTIVES: The aim of this study was to determine the performances of different stents in the treatment of bifurcation lesions using the re-proximal optimization technique (rePOT). METHODS: Eleven stent platforms were evaluated: Xience Sierra (Abbott), Xience Alpine (Abbott), Synergy (Boston), Coroflex Isar (Bbraun), Cobra PzF (Celonova), Ultimaster (Terumo), Resolute Integrity (Medtronic), Resolute Onyx (Medtronic), Optimax (Hexacath), Orsiro (Biotronik), and Absorb (Abbott). Stents were deployed in a silicone fractal bifurcation model using the rePOT. Micro-computed tomography was performed to assess side branch ostium coverage and strut malapposition, as well as the effect of rePOT on stent cell area. RESULTS: Our study showed significant differences between stent platforms regarding side branch ostium coverage (p = .002). The Synergy and Cobra PzF stents were the most performant devices to avoid ostium coverage. Strut malapposition varied significantly between devices (p = .008) but the percentage of malapposed struts was relatively low. Significant differences were observed between stents regarding the cell area before (p = .002) and also after rePOT (p = .003), and the increase in cell area caused by rePOT varied considerably between devices (p = .08). CONCLUSION: This study highlighted significant differences in the performances of stent platforms deployed in a fractal bifurcation model using rePOT, with a variable impact of the procedure on stent cell area.

POT-sideDCB-POT: A novel technique for treating coronary bifurcation lesions.

The rePOT technique is a novel and easily applied approach for coronary bifurcations. Drug-Coated Balloon (DCB) angioplasty is increasingly being utilized in management of small vessels and coronary bifurcation lesions. Herein, we propose a new approach for treating coronary bifurcation lesions with the application of DCB to treat the side-branch in addition to the rePOT technique: the POT-sideDCB-POT technique.

Restoration of antegrade ejaculation after transurethral bladder neck injection of Deflux for retrograde ejaculation: a case report of natural conception.

Retrograde ejaculation contributes to male infertility. Pharmacotherapy has a limited role in retrograde ejaculation. Deflux, a viscous substance, consists of two components: dextranomer microspheres and stabilized hyaluronic acid for the treatment of children with vesicoureteral reflux. According to the published articles, the authors described the first case achieved not only restoration of antegrade ejaculation but also followed conception of the spouse after transurethral bladder neck injection of Deflux. A 30-year-old male kept infertile after 3 years of marriage. The patient reported that he could not ejaculate in an antegrade direction after puberty when he reached sexual climax. There was no semen expulsed from the urethral meatus. Medicine prescribed by a local hospital didn't restore normal ejaculation. Four embryos fertilized by intracytoplasmic sperm injection developed well until transplantation, but none survived. The local reproductive center confirmed that his spouse preserved full capacity of fertility. He was diagnosed as retrograde ejaculation by real-time monitoring of transrectal ultrasound. He received transurethral bladder neck injection of Deflux. One month later, the patient restored antegrade ejaculation and the spouse of the patient conceived. During 18 months of follow-up, no related complications of the surgery have been observed. Transurethral bladder neck injection of Deflux can be considered as an alternative treatment method for retrograde ejaculation, and natural conception is possible thereafter.

Sequential coronary bifurcation revascularization with the Xposition S™ self-apposing stent: a comparative fractal bench study.

Coronary bifurcation revascularization needs to take account of the diameter differential between vessels and to limit side-branch obstruction (SBO). The self-apposing properties of the Xposition S™ stent (STENTYS, France) seem interesting in this regard. The present experimental fractal bench study determined the best provisional stenting technique using Xposition S™. Three sequential strategies were compared (n = 5/group): implantation alone, side-branch inflation (SBI), and re-POT (initial proximal optimization technique (POT) + SBI + final POT). 2D- and 3D-OCT analyses and micro-CT scan were performed to quantify the main mechanical results at each step. Of the three groups, SBI and re-POT provided better final results than implantation alone in terms of residual SBO (respectively, 24.6 ± 5.6% and 24.8 ± 5.0% vs. 46.5 ± 10.3%, p < 0.05) and malapposition (respectively, 0.9 ± 0.6% and 0.8 ± 0.4% vs. 3.8 ± 1.9%, p < 0.05). Unlike SBI, the two POTs of the re-POT sequence did not improve the final result. SBI, alone or as part of re-POT, systematically led to one connector breakage, whereas implantation alone maintained complete stent integrity (p < 0.05). In Xposition S™ implantation, SBI should be systematic, but not post-dilatation specifically dedicated to bifurcation stenting (i.e., POTs). However, global post-dilatation is still mandatory to prevent stent underexpansion due to untreated stenosis.

Congenital absence of vas deferens and ectopic kidney.

INTRODUCTION: Congenital absence of the vas deferens (CUAVD) is a rare clinical entity, usually discovered accidently during surgical procedures of the urogenital zone, CUAVD has the prevalence of 0.5-1.0% in male population and it is associated with various forms of congenital genitourinary malformations like renal agenesis. we present a case of a 21 years old, male, managed in our private hospital for varicoceles and discovered to have CUAVD and ectopic kidney. PRESENTATION OF CASE: A 21 years old male, with no significant medical or surgical history presented to our out-patient clinic complaining of scrotal heaviness and pain. upon physical examination he was discovered to have a bilateral varicocele and was scheduled for a bilateral varicocelectomy, during the procedure he was discovered with left side CUAVD. DISCUSSION: Congenital unilateral absence of the vas deference is a very rare clinical entity in the male population it has an incidence of 0.5-1.0%. it is usually discovered during evaluation for infertility or surgical procedures of the urogenital zone. Unilateral congenital absence of the vas deference is more associated with renal agenesis (73.3%), compared to the bilateral form (11.8%). CAVD is responsible of 1-2% of male infertility. CONCLUSION: Congenital absence of the vas deference is a unique clinical entity due to its great association with a large variety of urogenital abnormalities, we present this case to stress the importance of including scrotal examination in the routine physical exam to reduce the late diagnosis of such abnormality and it associated comorbidities.
