Frequency and timing of renal biopsy complications.

Background: Percutaneous renal biopsy is the primary diagnostic tool for renal diseases. In this study, we evaluated renal biopsy complications and the timing of complications. Methods: A cross-sectional study was performed on adult patients who underwent renal biopsy. The data gathering sheet collected patient characteristics. Complications were categorized as minor and major which needed an intervention. Data were analyzed using SPSS, and a p-value <0.05 was considered significant. Results: This cross-sectional study was conducted on 215 patients (mean age: 33.1±16.4 and 54.4%: women) who underwent percutaneous renal biopsy in Shiraz Nemazi Hospital for one year. Of the 298 complications that occurred, 90.2% were minors (56.1%of them microscopic hematuria). Moreover, 2 (0.7%) patients developed major complications and received a transfusion. In addition, most of the complications (98.9%, 295 ones) developed within 8 hours post-procedure. Only hemoglobin drop was significantly higher in women (41.0% vs. 21.4%, P=0.003). Conclusion: This study indicates that renal biopsy is a safe procedure; the results revealed that the significant post-biopsy complications were rare and occurred in the first 8 hours.

Impulse control disorders in hyperprolactinemic patients on dopamine agonist therapy.

Dopamine agonists (DAs) represent a mainstay of therapy for hyperprolactinemia and prolactinomas. The widespread use of DAs, including bromocriptine, cabergoline and (in some countries) quinagolide, has led to the emergence and recognition of impulse control disorders (ICDs) that may occur in association with DA therapy.Such ICDs include pathological gambling, compulsive shopping, hypersexuality and punding (the performance of repetitive tasks), among others. These manifestations can lead to substantial harms to patients and their families, if left undiagnosed and untreated. Several risk factors that may increase the risk of ICDs have been proposed, including younger age, male gender, smoking and alcohol use and history of depression.The diagnosis of ICDs in hyperprolactinemic patients treated with DAs requires a high index of suspicion and a systematic approach, using available screening questionnaires. However, it should be noted that available test instruments, including questionnaires and computerized tasks, have not been validated specifically in hyperprolactinemic patients. Hyperprolactinemic patients who develop ICDs should be withdrawn from DA therapy or, at a minimum, undergo a DA dose reduction, and considered for psychiatric consultation and cognitive behavioral therapy. However, the role of psychopharmacotherapy in hyperprolactinemic patients with ICDs remains incompletely characterized.Patient counseling regarding the risk of ICDs occurring in association with DA therapy, early detection and prompt intervention may mitigate potential harms associated with ICDs. Additional studies are needed to fully characterize risk factors, underlying mechanisms and identify effective therapies for ICDs in patients with hyperprolactinemia receiving DAs.

Non-medial infectious orbital cellulitis: etiology, causative organisms, radiologic findings, management and complications.

BACKGROUND: Orbital cellulitis is an ophthalmic emergency, which is associated with vision-threatening adverse effects. The purpose of this study is investigating etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis. METHOD: A retrospective medical record and radiologic file review of patients with infectious orbital cellulitis was performed to detect all patients with non-medial orbital cellulitis who referred to Khalili hospital from 2016 to 2019. Age, sex, origin of infection, size of collection or abscess, medical or surgical management, microbiology, first and final best-corrected visual acuity, duration of admission, and complications was recorded. Patients divided into two groups; medical management and surgical management groups and all of data compared between in this groups. RESULTS: Of ninety-six patients with infectious orbital cellulitis, 23 cases (14 male, 9 female) were included. Five patients (21.7%) were managed medically and 18 patients (78.3%) were managed surgically. Patients' age range was 5-70 years old. Most common location for non-medial cellulitis was superior space (66.7% in surgical and 40% in medical group; p = 0.511). In 13 cases of surgical group (72.3%) were detected microorganisms. The mean ± SD of collection volume in medical group were 476.5 ± 290.93 mm3 and 2572.94 ± 1075.75 mm3 in surgical group (p < 0.001). Ten patients in surgical group had compressive optic neuropathy. The mean ± SD of collection volume was 3204.97 ± 879.88 mm3 in patient with compressive optic neuropathy and 1280.43 ± 880.68 mm3 in patient without compressive optic neuropathy (P < 0.001). One case complicated by subdural empyema and another case progressed to necrotizing fasciitis. CONCLUSION: Non-medial orbital cellulitis is an uncommon but sight-threatening and life-threatening condition. Timely diagnosis and accurate management reduce morbidity and mortality. Combined surgery for patients with superior or supra-temporal and large non-medial abscess is recommended.
