Neurological and neuropsychiatric manifestations of porphyria.

Porphyrias are inherited disorders of the heme biosynthetic pathway, usually characterized by dermatological changes due to the accumulation of byproducts in the pathway. Select porphyrias also affect the nervous system, namely hereditary coproporphyria, acute intermittent porphyria and variegate porphyria. Complications include paralysis, hyponatremia which can risk central pontine myelinolysis, seizures and coma. Neurological complications usually result from severe episodes of acute attacks. Acute attacks may also elicit neuropsychiatric symptoms such as confusion, hallucinations, anxiety and psychosis. However, these manifestations are generally self-limiting. Due to the generally low incidence of porphyria and full knowledge the associated neurological and psychiatric manifestations, we review the relevant porphyrias along with their clinical manifestations, evaluation, and management to raise its awareness in the clinical picture and to prevent misdiagnosis. Porphyria should be considered within the differential diagnosis for unexplained neurological symptoms.

Genitourinary syndrome of menopause: an overview of clinical manifestations, pathophysiology, etiology, evaluation, and management.

Genitourinary syndrome of menopause, a new term for a condition more renowned as atrophic vaginitis, is a hypoestrogenic condition with external genital, urological, and sexual implications that affects >50% of postmenopausal women. Due to sexual embarrassment and the sensitive nature of discussing symptoms, genitourinary syndrome of menopause is greatly underdiagnosed. The most up-to-date literature pertaining to clinical manifestations, pathophysiology, etiology, evaluation, and management of genitourinary syndrome of menopause is comprehensively reviewed. Early detection and individually tailored pharmacologic (eg, estrogen therapy, selective estrogen receptor modulator, synthetic steroid, oxytocin, and dehydroepiandrosterone) and/or nonpharmacologic (eg, laser therapies, moisturizers and lubricants, homeopathic remedies, and lifestyle modifications) treatment is paramount for not only improving quality of life but also for preventing exacerbation of symptoms in women with this condition.

Renal Innervation in Resistant Hypertension: A Review of Pathophysiology and Renal Denervation as Potential Treatment.

BACKGROUND: Advances in treatment and increased awareness have improved the prognosis for many patients with hypertension (HTN). Resistant hypertension (RH) refers to a subset of hypertensive individuals who fail to achieve a desired blood pressure (BP) despite concurrent use of 3 different classes antihypertensive agents, one being a diuretic, and proper lifestyle changes. The prevalence and prognosis of RH are unclear owing to its heterogeneous etiologies, risk factors, and secondary comorbidities. Previous research has provided evidence that increased renal sympathetic nerve activity (RSNA) within the renal artery contributes to RH development. Renal denervation (RDN) is a procedure that attempts to ameliorate the effects of heightened RSNA via ablation renal sympathetic fibers. BP reductions associated with RDN may be attributed to decreased norepinephrine spillover, restoration of natriuresis, increasing renal blood flow, and lowering plasma renin activity. Early clinical trials perpetuated positive results, and enthusiasm grew exponentially. However, recent clinical trials have called into question RDN's efficacy. Numerous limitations must be addressed to discern the true effectiveness of RDN as a therapeutic option for RH. OBJECTIVE: We aimed to review the current understanding of RH, the anatomy of renal arteries, physiology of RH on renal arteries, anatomical pathways of the sympathetic involved in RH, RDN as a treatment option, and all relevant clinical trials treating RH with RDN. METHODS: We piloted a MEDLINE® database search of literature extending from 1980 to 2017, with emphasis on the previous five years, combining keywords such as "resistant hypertension" and "renal denervation." CONCLUSION: A plethora of information is available regarding heightened RSNA leading to RH. RDN as a possible treatment option has shown a range of results. Reconciling RDN's true efficacy requires future trials to increased sites of nerve ablation, standardized protocol, increased anatomical understanding per individual basis, stricter guidelines regarding study design, increased operator experience, and integrating the use of a multielectrode catheter.

Clinical utility of hyperbaric oxygen therapy in dentistry.

This fuller impact of the use of hyperbaric oxygen therapy within dentistry is taking greater notice with newer research findings. There are new advancements in research regarding postradiotherapy cases, osteonecrosis of the jaw, osteomyelitis, periodontal disease, and dental implants. Hyperbaric oxygen therapy can even be used in conjunction with other procedures such as bone grafting. Although the research and clinical utility has come a long way, there are several complications to be mindful of during the application of hyperbaric oxygen therapy.

Clinical utility of ozone therapy in dental and oral medicine.

Ozone is a highly reactive compound composed of three oxygen atoms that acts as an oxidant and oxidizer. It exists at the ground level as an air pollutant and a constituent of urban smog, as well as in the Earth's upper atmosphere as a protective layer from ultraviolet rays. Healthy cells contain antioxidants such as vitamins C and E to protect against ozone oxidization. However, pathogens such as bacteria contain very trace amounts of antioxidants in their membranes, which make them susceptible to ozone and destroy the cell membrane. This review explores the history, composition, and use of ozone worldwide in dentistry. Ozone therapy has thus far been utilized with wound healing, dental caries, oral lichen planus, gingivitis and periodontitis, halitosis, osteonecrosis of the jaw, post-surgical pain, plaque and biofilms, root canals, dentin hypersensitivity, temporomandibular joint disorders, and teeth whitening. The utility of ozone will undoubtedly grow if studies continue to show positive outcomes in an increasing number of dental conditions.

Classifying Hydroceles of the Pelvis and Groin: An Overview of Etiology, Secondary Complications, Evaluation, and Management.

INTRODUCTION: A hydrocele is defined as the pathological buildup of serous fluid in the pelvis and groin due to various etiologies such as diseases or trauma. It has distinct clinical manifestations, particularly discomfort and psychosocial distress. Understanding the anatomy, embryology, and physiology associated with hydrocele formation is crucial to understand its onset and progression. MATERIALS AND METHODS: A MEDLINE® search was conducted using keywords for the relevant classification of hydrocele and its etiology, complications, sexual barriers, evaluation, and management. RESULTS: Appropriately classifying the hydrocele as primary, secondary communicating, secondary noncommunicating, microbe-induced, inflammatory, iatrogenic, trauma-induced, tumor-induced, canal of Nuck, congenital, and giant is important for identifying the underlying etiology. Often this process is overlooked when the classification or etiology is too rare. A focused evaluation is important for this, so that timely management can be provided. We comprehensively review the classifications, etiology, and secondary complications of hydrocele. Pitfalls of current diagnostic techniques are explored along with recommended methods for accurate diagnosis and current treatment options. CONCLUSION: Due to the range of classifications and etiologies of hydrocele in the pelvis and groin, a deliberate differential diagnosis is essential to avoiding imminent life-threatening complications as well as providing the appropriate treatment.

Etiologic classification, evaluation, and management of hematospermia.

Hematospermia is defined by the presence of blood in the semen typically occurring in men younger than 40 years of age. Symptoms can occur due to a multitude of reasons, but are usually benign and self-limiting, requiring no additional treatment or evaluation. Despite this, the condition often impairs quality of life due to associated anxiety and must be taken seriously by the patient and the physician, particularly if recurrent, refractory, and painful. The etiology of hematospermia can be classified into inflammatory, infectious, lithiasis, cystic, obstructive, tumoral, vascular, traumatic, iatrogenic, and systemic origin. Alternatively, it can also be divided into subcategories based on anatomical origins such as prostate, bladder, spermatic cord, seminal vesicles, or epididymis. A complete history and physician examination, laboratory testing, and a variety of invasive and non-invasive imaging and instrumentation modalities can help to identify and treat the underlying pathology promptly.

Detecting diseases of neglected seminal vesicles using imaging modalities: A review of current literature.

Seminal vesicles (SVs) are sex accessory organs and part of male genitourinary system. They play a critical role in male fertility. Diseases of the SVs, usually results in infertility. Diseases of the SVs are extremely rare and are infrequently reported in the literature. We address the current literature of SV pathologies, symptoms, diagnosis, and treatment options. We review the clinical importance of SVs from PubMed. The current imaging modalities and instrumentation that help diagnose SV diseases are reviewed. Common pathologies including, infection, cysts, tumors, and congenital diseases of the SVs are addressed. Many times symptoms of hematospermia, pain, irritative and obstructive lower urinary tract symptoms, and infertility are presented in patients with SV diseases.

Urological complications of uterine leiomyoma: a review of literature.

INTRODUCTION: Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. OBJECTIVE: The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. METHODS: Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. RESULTS: Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. CONCLUSION: Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

Unusual Glomus Tumor of the Penis.

INTRODUCTION: Glomus tumors are benign neoplasms commonly found in subungual regions of the extremities and rarely located in the penis. Misdiagnosis of glomus tumors is common; therefore, symptoms and clinical presentations should be reviewed. OBJECTIVE: The primary objective of this review article is to emphasize the pathogenesis, pathology, clinical presentation, symptoms, diagnosis, and treatment methods of glomus tumors in order to better identify and manage the condition. MATERIALS AND METHODS: Research was conducted using PubMed/Medline. The inclusion criteria required glomus tumor to be present on the penis. RESULTS: Glomus tumors, which appear as symptomatic or asymptomatic lesions, are attributed to dispersion grouping of neoplastic or non-neoplastic lesions in a particular area. CONCLUSION: Differential diagnosis of glomus tumors includes hemangiomas, neurofibromatosis, epithelial lesions, and spindle-cell lesions. Physical examination and histological findings should be used for diagnosis. Treatment options can be either conservative or invasive, in which the patient undergoes surgical excision.
