Frequency and Effect of Cutaneous Manifestations on Quality of Life in Patients with End-Stage Renal Disease Undergoing Hemodialysis.

OBJECTIVE: To determine the frequency of skin manifestations found in end-stage renal disease (ESRD) patients undergoing dialysis, while assessing their effect on the quality of lives of the same patients. STUDY DESIGN: Descriptive cross-sectional study. Place and Duration of the Study: Benazir Bhutto Hospital, Holy Family Hospital, and Hussain Lakhani Hospital, from 12th December 2021 to 13th October 2022. METHODOLOGY: Seventy-three Patients undergoing hemodialysis were enrolled in the study. Skin manifestations were defined as "cutaneous signs and symptoms related to ESRD unrelated to the symptoms resulting from any primary dermatological disorder or other systemic diseases". Data on the skin manifestations of their disease and their effect on patients' quality of life were collected by using a 2-part questionnaire. The first part consisted of demographic details along with the type of skin disorders faced by the patient and the second part of the questionnaire comprised of the dermatology life quality index (DLQI). The data were entered and analysed using the statistical package for social sciences (SPSS) version 23.0. RESULTS: Xerosis and pruritus were most commonly reported (83.7%), followed by nail changes (18.6%) and skin discolouration (16.3%). The median duration of dialysis was 36 (1-180) months and there was no significant increase in skin symptoms with the increase in the duration of dialysis (p=0.082). The median DLQI score was 3 (range:0-10) A significantly higher number of females (n=14) reported associated mental discomfort with their skin symptoms of pruritis as compared to males (n=5, p=0.008). CONCLUSION: Cutaneous manifestations have variable effects on the quality of life of ESRD patients. Adopting a multidisciplinary approach early in the management may help to minimise the mental discomfort of these patients and bring an improvement in their quality of life. KEY WORDS: End-stage renal disease (ESRD), Hemodialysis, Skin manifestations, Pruritus, Quality of life.

Philosophy of dermatology and the uneven road to realizing it: Perspective from a third-world country.

The philosophy of dermatology involves helping patients who present to dermatologists to realize their full potential by treating them holistically and educating them about the different aspects of their disease(s), while helping the doctors involved to grow professionally and as human beings. In the setting of a burdened health sector of a third-world country like Pakistan, the road to realizing this philosophy is rife with hurdles in the form of low resources, poor health infrastructure, lack of a research culture, a low literacy rate, and sociocultural taboos. The resolution of these issues needs concerted efforts by all the stakeholders, and it can be possible only through selfless leadership, dedicated teamwork, and incessant efforts by the doctors, health authorities, and national as well as international health institutions.

Mite is right: A case of infected scabies masquerading as a blistering disorder.

Scabies classically presents with itching and skin lesions in the interdigital spaces of hands, trunk, and genitals. Rarely, non-classical skin lesions can result in misdiagnosis and inappropriate management of patients.

General Anaesthesia Versus Regional Anaesthesia For Lumbar Laminectomy: A Review Of The Modern Literature.

BACKGROUND: Lumbar spine surgery can be performed using different anaesthetic techniques such as general endotracheal anaesthesia (GA) or spinal-based regional anaesthesia (RA). Few of the studies have been done to compare the outcomes of spinal anaesthesia versus general anaesthesia for lumbar laminectomies as both having some advantages as well as disadvantages but still it is controversial. The objective of current study is to make a comprehensive review of literature for comparing the outcomes of lumbar laminectomy performed under general anaesthesia versus spinal anaesthesia. METHODS: Literature search was performed by using PubMed, Google scholar and bibliography of related articles. To compare groups of general anaesthesia versus spinal anaesthesia, the variables focused were mean heart rate (HR), mean arterial pressure (MAP), blood loss during surgery, duration of surgery, post-operative anaesthesia care unit (PACU) time, postoperative narcotic use/pain scale, post-operative urinary retention, and post-operative nausea/vomiting. RESULTS: Data of eleven studies were presented in current article, of these five were randomized controlled trials, three case-controls and four were retrospective cohort studies. 5/8 studies reported that SA group having more hemodynamic stability with postoperative outcomes as compared to GA. Likewise, majority of reviewed studies (7/8) reported better pain control or decreased requirement of analgesics in SA group. Additionally, more than half of the reviewed studies (5/8) reported lower incidence of postoperative nausea and vomiting among patients of SA group.. CONCLUSIONS: The current study concluded that SA has better outcomes than GA in terms of hemodynamic stability and decrease postoperative adverse effects. So special attention should be paid for SA as an alternative to GA for lumbar laminectomy.

Dupilumab for Atopic Dermatitis: The Silver Bullet We Have Been Searching for?

Atopic dermatitis is a chronic inflammatory condition of the skin affecting a large number of people worldwide. Historically, this condition has been managed by topical corticosteroids and general skincare measures. The inadequacy of these management strategies has always driven efforts to find better drugs. Dupilumab has been recently approved for the management of atopic dermatitis. It is a human monoclonal antibody that inhibits the binding of key interleukins involved in the pathogenesis of atopic dermatitis, thus blocking the signaling mechanisms and disrupting the disease progression. Dupilumab reduces the severity and associated symptoms of atopic dermatitis. It improves the life quality of patients and reduces the anxiety associated with the disease. Combination therapy of dupilumab and topical corticosteroids is more effective than dupilumab monotherapy. The treatment-related adverse events include headache, injection site reaction, conjunctivitis, nasopharyngitis, and herpes viral infections. Moreover, the simultaneous use of live vaccines with dupilumab is contraindicated. It is also beneficial in the management of asthma, chronic rhinosinusitis, and eosinophilic esophagitis. In this review, we have discussed the clinical efficacy and safety profile of dupilumab in the management of atopic dermatitis.

Leptin and reproductive dysfunction in obese men.

Infertility is somewhat more prevalent in men who are obese. They are also reported to have low sperm concentration, higher fraction of spermatozoa that look morphologically abnormal, higher DNA fragmentation index and evidence of oxidative stress. The precise cause for this remains uncertain. Leptin levels in serum and percentage body fat correlate positively, and obese men therefore usually have elevated serum leptin levels. Although leptin is important for normal reproductive function, but when present in excess, leptin could seriously affect reproductive function in men. Reports on the findings of sperm parameters in obese men, particularly those who are subfertile or infertile, seem to be similar to those reported from studies on normal-weight rats treated with leptin. Collectively, the observations reported in human and experimental animal studies point to leptin as a possible link between infertility and obesity. Herein, we review some findings on sperm function in obese subfertile or infertile men and those from animal studies following leptin treatment, and discuss the possible link between leptin and reproductive dysfunction in obese men. The large amounts of leptin secreted by the adipose tissue and its higher circulating levels could indeed be responsible for the higher prevalence of infertility in obese men.

Assessment of Knowledge, Attitude, and Practices Regarding Self-medication for Acne Among Medical Students.

Introduction Acne is one of the most common skin conditions worldwide. Self-medication for acne is a fairly common practice among medical students. The objective of our study was to identify the prevalence of self-medication and to assess its knowledge, attitude, and practices among medical students. Materials and methods This descriptive cross-sectional study was conducted at Rawalpindi Medical University, Rawalpindi, Pakistan, from January 2019 to June 2019. Data were collected by using the convenient sampling technique. Students were asked to fill a semi-structured questionnaire. Students of all the medical years studying in our university were included in the study. Data were entered and analyzed using the Statistical Package for Social Sciences (SPSS) version 23.0 (IBM Corp., Armonk, US). Results Out of 349 students, 244 (69.9%) suffered from acne and self-medication was practiced by 123 (50.4%) acne sufferers. The practice of self-medication was significantly higher in students having acne lesions on the face (52.2%). The most common source of information was reported to be acquaintances (55.8%). Most of the students had knowledge of the dosage of drugs (46.3%) and precautions for their use (41.5%). Sixty-three percent of the students were of the opinion that self-medication is part of self-care. Most of the students read the expiration date on the drug label (88.6%). Conclusion Acne is a highly prevalent condition among medical students and the practice of self-medication among acne sufferers is high. The practice of self-medication and visits to dermatologists were both significantly more common in the students with lesions on the face. The knowledge of students regarding self-medication of acne was not adequate.

LY294002, a PI3K pathway inhibitor, prevents leptin-induced adverse effects on spermatozoa in Sprague-Dawley rats.

This study examined the effects of PI3K and AMPK signalling pathway inhibitors on leptin-induced adverse effects on rat spermatozoa. Sprague-Dawley rats, aged 14-16 weeks, were randomised into control, leptin-, leptin + dorsomorphin (AMPK inhibitor)-, and leptin+LY294002 (PI3K inhibitor)-treated groups with six rats per group. Leptin was given once daily for 14 days via the intraperitoneal (i.p.) route at a dose of 60 ug kg-1 body weight. Rats in the leptin and inhibitor-treated groups received concurrently either dorsomorphin (5 mg kg-1  day-1 ) or LY294002 (1.2 mg kg-1  day-1 ) i.p. for 14 days. Controls received 0.1 ml of normal saline. Upon completion, sperm count, sperm morphology, seminiferous tubular epithelial height (STEH), seminiferous tubular diameter (STD), 8-hydroxy-2-deoxyguanosine (8-OHdG) and phospho-Akt/total Akt ratio were estimated. Data were analysed using ANOVA. Sperm count, STEH and STD were significantly lower, while the percentage of spermatozoa with abnormal morphology and the level of 8-OHdG were significantly higher in rats treated with leptin and leptin + dorsomorphin when compared to those in controls and LY294002-treated rats. Testicular phospho-Akt/total Akt ratio was significantly higher in leptin and leptin + LY294002-treated rats. In conclusion, LY294002 prevents leptin-induced changes in rat sperm parameters, suggesting the potential role of the PI3K signalling pathway in the adverse effects of leptin on sperm parameters.

Leptin and its actions on reproduction in males.

Leptin, an adipocyte-derived hormone, serves numerous physiological functions in the body, particularly during puberty and reproduction. The exact mechanism by which leptin activates the gonadotropin-releasing hormone (GnRH) neurons to trigger puberty and reproduction remains unclear. Given the widespread distribution of leptin receptors in the body, both central and peripheral mechanisms involving the hypothalamic-pituitary-gonadal axis have been hypothesized. Leptin is necessary for normal reproductive function, but when present in excess, it can have detrimental effects on the male reproductive system. Human and animal studies point to leptin as a link between infertility and obesity, a suggestion that is corroborated by findings of low sperm count, increased sperm abnormalities, oxidative stress, and increased leptin levels in obese men. In addition, daily leptin administration to normal-weight rats has been shown to result in similar abnormalities in sperm parameters. The major pathways causing these abnormalities remain unidentified; however, these adverse effects have been attributed to leptin-induced increased oxidative stress because they are prevented by concurrently administering melatonin. Studies on leptin and its impact on sperm function are highly relevant in understanding and managing male infertility, particularly in overweight and obese men.
