Superpulsed CO 2
Background. Periorbital basal cell carcinoma (BCC) is considered a high risk case because it is associated with high rate of recurrence and complication. Superpulsed CO2 laser with intraoperative pathologic assessment could be an alternative and appropriate treatment for periocular lesions where Mohs micrographic surgery is not available. Objective. To evaluate the efficacy of superpulsed CO2 laser therapy with intraoperative pathologic assessment on periocular BCC involving eyelash line. Method. This follow-up study was performed on 20 patients with a total of 21 BCC lesions that were pathologically documented. Firstly, debulkation of tumoral mass was done by curettage. Then, irradiation and intraoperative pathologic evaluation were done by concurrent CO2 laser. The patients were followed up for a period of 36 months. Results. Out of 21 lesions, the nodular type accounted for 15 (71.4%) lesions, and 12 (57.1%) lesions were seen in the lower lid as the most common clinical type and site involvement. Twenty BCC lesions (95.2%) were treated after one session. Damage to eyelash was seen in 2 (10%) patients, but ectropion and other complications were not seen in any patient. Conclusion. Treatment with superpulsed CO2 laser and intraoperative pathologic evaluation for periorbital BCC lesions much close to conjunctiva could be an effective method with minimal complications without major danger of recurrence. This modality can be used with care in the inner canthus and high risk pathologic lesions
Clinical Features and Drug Characteristics of Patients with Generalized Fixed Drug Eruption in the West of Iran (2005–2014)
Background. Generalized fixed drug eruption is a specific variant of fixed drug eruption with multifocal lesions. Diagnosis of this drug reaction is straightforward, but occasionally recognition of the causative drug is not possible. This study was aimed at evaluating the clinical features and culprit drugs in generalized fixed drug eruptions in the west of Iran. Method. This cross-sectional study was carried out on 30 patients with criteria of generalized fixed drug eruption over 9 years. Demographic, clinical, and drug intake information were collected. Results. Out of 30 patients (17 females and 13 males) with the mean age of 26.67±10.21 years, 28 (93.3%) and 2 (6.7%) cases had plaque and bullous clinical presentation, respectively. Upper limbs were the most common (90%) site of involvement. The antibiotic group, especially cotrimoxazole (26.1%), was reported to be the most common offending drug, but the causative drug was not determined in 7 (23.3%) patients. Conclusion. Many cases of generalized fixed drug eruption firstly presented as limited lesions and led to generalized lesion due to repeated intake of the causative drug. No causative drug was found in some patients, which might be associated with concurrent intake of several drugs, multiple FDE, and peculiarity of the patch test
Gross hematuria as the presentation of an inguinoscrotal hernia: a case report
<p>Abstract</p> <p>Introduction</p> <p>Several complications have been reported with inguinal hernias. Although hematuria and flank pain, either as the presentation or as a complication of inguinal hernia, are infrequent, this condition may lead to the development of obstructive uropathy, which can have diverse manifestations.</p> <p>Case presentation</p> <p>A 71-year-old Iranian man with Persian ethnicity presented with new onset episodes of gross hematuria and left-sided flank pain. A physical examination revealed a large and non-tender inguinal hernia on his left side. An initial workup included an abdominal ultrasound, an intravenous pyelogram and cystoscopy, which showed left hydronephrosis and a bulging on the left-side of his bladder wall. On further evaluation, computed tomography confirmed that his sigmoid colon was the source of the pressure effect on his bladder, resulting in hydroureteronephrosis and hematuria. No tumoral lesion was evident. Herniorrhaphy led to the resolution of his signs and symptoms.</p> <p>Conclusion</p> <p>Our case illustrates a rare presentation of inguinal hernia responsible for gross hematuria and unilateral hydronephrosis. Urologic signs and symptoms can be caused by the content of inguinal hernias. They can also present as complications of inguinal hernias.</p
Male Oxidative Stress Infertility (MOSI): Proposed Terminology and Clinical Practice Guidelines for Management of Idiopathic Male Infertility
Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen
characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose
and manage. Increasing evidence suggests that oxidative stress (OS) plays an independent role in the etiology of male
infertility, with 30% to 80% of infertile men having elevated seminal reactive oxygen species levels. OS can negatively affect
fertility via a number of pathways, including interference with capacitation and possible damage to sperm membrane and
DNA, which may impair the sperm’s potential to fertilize an egg and develop into a healthy embryo. Adequate evaluation of
male reproductive potential should therefore include an assessment of sperm OS. We propose the term Male Oxidative Stress
Infertility, or MOSI, as a novel descriptor for infertile men with abnormal semen characteristics and OS, including many
patients who were previously classified as having idiopathic male infertility. Oxidation-reduction potential (ORP) can be a
useful clinical biomarker for the classification of MOSI, as it takes into account the levels of both oxidants and reductants
(antioxidants). Current treatment protocols for OS, including the use of antioxidants, are not evidence-based and have the
potential for complications and increased healthcare-related expenditures. Utilizing an easy, reproducible, and cost-effective
test to measure ORP may provide a more targeted, reliable approach for administering antioxidant therapy while minimizing
the risk of antioxidant overdose. With the increasing awareness and understanding of MOSI as a distinct male infertility diagnosis,
future research endeavors can facilitate the development of evidence-based treatments that target its underlying cause
Reactive oxygen species and male reproductive hormones
Reports of the increasing incidence of male infertility paired with decreasing semen quality have triggered studies
on the effects of lifestyle and environmental factors on the male reproductive potential. There are numerous exogenous
and endogenous factors that are able to induce excessive production of reactive oxygen species (ROS) beyond that of
cellular antioxidant capacity, thus causing oxidative stress. In turn, oxidative stress negatively affects male reproductive
functions and may induce infertility either directly or indirectly by affecting the hypothalamus-pituitary-gonadal (HPG)
axis and/or disrupting its crosstalk with other hormonal axes. This review discusses the important exogenous and
endogenous factors leading to the generation of ROS in different parts of the male reproductive tract. It also highlights
the negative impact of oxidative stress on the regulation and cross-talk between the reproductive hormones. It further
describes the mechanism of ROS-induced derangement of male reproductive hormonal profiles that could ultimately
lead to male infertility. An understanding of the disruptive effects of ROS on male reproductive hormones would
encourage further investigations directed towards the prevention of ROS-mediated hormonal imbalances, which in turn
could help in the management of male infertility
