Background: Hereditary hypotrichosis simplex is a rare genetic hair disease that affects the scalp. Failure to grow normal hair in terms of length and density is the main complaint of patients. Diagnosis usually established by exclusion of other congenital hair and other ectodermal disorders. Till now, no satisfactory treatment was used for the condition. Report: A 14 year old patient with hypotrichosis simplex was treated with combined platelet rich plasma injection and topical minoxidil 2% with marked improvement. Conclusion: While no satisfactory treatment presents for this condition, the use of platelet rich plasma injection can add new hope for hypotrichosis simplex patients.

The rate of infectious diseases started to be one of the major mortality agents in the healthcare sector. Exposed to increased bacterial infection by antibiotic-resistant bacteria became one of the complications that occurred for bone marrow transplant patients. Nanotechnology may provide clinicians and patients with the key to overcoming multidrug-resistant bacteria. Therefore, this study was conducted to clarify the prevalence of MDR bacteria in bone marrow transplant recipients and the use of Ag 2 O/ZnO nanocomposites to treat participants of diarrhea brought on by MDR bacteria following bone marrow transplantation (BMT). Present results show that pathogenic bacteria were present in 100 of 195 stool samples from individuals who had diarrhea. Phenotypic, biochemical, and molecular analysis clarify that Proteus mirabilis and Salmonella typhi were detected in 21 and 25 samples, respectively. Successful synthesis of Ag 2 O/ZnO nanocomposites with a particle enables to inhibition of both pathogens. The maximum inhibitory impact was seen on Salmonella typhi. At low doses (10 -5 g/l), it prevented the growth by 53.4%, while at higher concentrations (10 -1 g/l), Salmonella typhi was inhibited by 95.5%. Regarding Proteus mirabilis, at (10 -5 g/l) Ag 2 O/ZnO, it was inhabited by 78.7%, but at higher concentrations (10 -1 g/l), it was inhibited the growth by 94.6%. Ag 2 O/ZnO nanocomposite was therefore found to be the most effective therapy for MDR-isolated bacteria and offered promise for the treatment of MDR bacterial infections that cause diarrhea., (© 2023.

Although oral isotretinoin has been considered as a potential therapeutic option for the treatment of different types of warts, the optimum dosage regimen is not yet well-established. To evaluate the efficacy and adverse effects of high versus low doses of oral isotretinoin in the treatment of cutaneous and genital warts. The study included 100 patients who were randomly assigned to two groups, 50 patients in each. Group 1 received 0.6 mg/kg/day (high dose isotretinoin) and Group 2 received 0.3 mg/kg/day (low dose isotretinoin). In both groups, therapy was given daily until resolution was achieved or for a maximum of 3 months. Complete clearance of warts was observed in 76% of the high dose isotretinoin group and in 46% of the low dose isotretinoin group. There was a statistically significant difference in the therapeutic response between the two groups. Recurrence was higher in the low dose group (26%) than the high dose group (7.8%). Adverse effects were mild and tolerable. High dose of systemic isotretinoin is more effective than low dose and seems to be a promising well-tolerated and effective therapeutic option for the treatment of cutaneous and genital warts., (© 2022 Wiley Periodicals LLC.)

Primary immune thrombocytopenic purpura (ITP) is an autoimmune disorder with platelet destruction due to B- and T-cell dysregulation and antiplatelet autoantibodies production. Flow cytometry can be used to further characterize the B- and T-cell compartments involved in platelet destruction. This case-control study was to enumerate plasmablast cells in pediatric ITP patients and to correlate their levels with disease course. This study included 30 ITP patients and 10 controls. Identification and enumeration of Plasmablast were done by multicolor flow cytometry using specific antibody panels (CD19, CD27 & CD38) and sequential gating using FACSCanto flow cytometer and FlowJo software. We found that lymphocytes subpopulation in ITP patients and controls revealed increase in frequency of CD19 (B lymphocytes) in acute, persistent, and chronic ITP patients in comparison with controls ( p  < 0.001, 0.023, 0.001) respectively. Plasmablast cells could play a role in the pathogenesis of ITP and might guide therapy in ITP patients in the future.

Background: Phototherapy (PT) is the most often utilized technique for treating and preventing severe hyperbilirubinemia in the term and preterm newborns. PT's proven benefit is that it decreases the requirement for exchange transfusions. To investigate the effect of PT on allergic response mediators in neonates with hyperbilirubinemia treated by PT, eosinophil counts and tumor necrosis factor alfa levels have been assessed., Methods: This cross-sectional study included 100 full-term infants with indirect hyperbilirubinemia in the first two weeks of life who were indicated for PT. They were investigated by tumor necrosis factor α and eosinophil counts before and 72 h after starting PT. The used tests were paired with Student's t-test and Pearson coefficient., Results: Relative and absolute eosinophil counts and tumor necrosis factor alfa were significantly higher after PT than before (p < 0.001). There was a significant positive correlation between total serum bilirubin and both tumor necrosis factor alfa and eosinophil % (r = 0.442 and r = 0.362, respectively, P < 0.001) before PT. There was a significant positive correlation between total serum bilirubin and both eosinophil count and eosinophil % (r = 0.281and r = 0.339), respectively (P < 0.001) after PT. There was a significant positive correlation between both tumor necrosis factor alfa and eosinophil % after PT (r = 0.545, P < 0.001)., Conclusions: Serum tumor necrosis factor-alpha and eosinophilic count increased after treatment of neonatal hyperbilirubinemia by PT, which indicates an allergic response to PT in neonates., (© 2022.

Background and Objectives: To compare the efficacy of autologous platelet-rich plasma (PRP), ablative fractional carbon dioxide (FCO 2 ) laser, and their combination in the treatment of atrophic acne scars, both clinically and immuno-histopathologically., Study Design/materials and Methods: Sixty patients were randomly divided into three equal groups. Group 1 received intradermal PRP injection sessions. Group 2 received FCO 2 laser sessions. Group 3 received FCO 2 laser followed by intradermal PRP injection sessions. Each group received three sessions at monthly intervals. The final assessment took place 3 months after the last session. Skin biopsies were obtained before and 1 month after treatment sessions with pathological evaluation., Results: Combined PRP and FCO 2 laser-treated patients had a better clinical response, fewer side effects, and shorter downtime than FCO 2 laser alone. PRP-treated patients had some improvement but significantly lower than the other two groups., Conclusion: The current study concluded that a combination of PRP and FCO 2 laser is an effective and safe modality in the treatment of atrophic acne scars with better results than PRP or FCO 2 laser alone.

Onychomycosis is a common chronic fungal infection of the nails caused by dermatophytes, yeasts, and non-dermatophyte filamentous fungi. A relatively high incidence of resistance and treatment failure of onychomycosis to traditional systemic antifungal agents such as terbinafine and itraconazole has been reported. Voriconazole is a novel broad spectrum systemic antifungal that has shown high efficacy against various types of dermatophytes including Trichophyton and Microsporum species in many in vitro and, recently, in two in vivo studies of resistant dermatophytosis. Herein, we report the successful treatment of a resistant case of finger nail onychomycosis by oral voriconazole in a liver transplant patient who failed to respond to traditional systemic antifungals., (© 2020 Wiley Periodicals LLC.)

Bromoderma is a rare hypersensitivity reaction caused by bromide intake. It was relatively frequent in the early years of the previous century because of the common use of bromide-containing solutions in pediatrics due to their antispasmodic, expectorant, sedative, and anticonvulsant effects. Although recently prohibited in many countries, bromides are still used as an adjuvant anticonvulsant drug and still present in some over the counter antispasmodics and analgesics. Bromoderma usually present with pustular and vegetating lesions that may represent a diagnostic challenge for dermatologists. We describe a severe case of vegetating bromoderma that showed an excellent response to the withdrawal of the bromide-containing medication associated with systemic steroid administration., (© 2020 Wiley Periodicals LLC.)

Background: The achievement of optimal number of CD34 + umbilical cord stem cells is essential for successful umbilical cord stem cell transplantation. So the aim of this study was to assess the potential effect of both maternal and neonatal factors on the umbilical cord blood CD34 + cell count., Methods: The study was done on umbilical cord blood samples obtained from 20 mothers during labor. Their ages ranged from 22 to 34 years and were subjected to history taking, physical examination of the baby and assessment of the CD34 + cells count in umbilical cord blood., Results: Number of previous live births and weight of the baby had a significant effect on CD34 + cells count while the sex of the baby, delivery route, maternal age and gestation period had no significant effect on CD34 + cells count., Conclusions: Umbilical cord blood-derived CD34 + cell count is better with good weight and first babies and decreased with subsequent babies., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2020 Stem Cell Investigation.

Background: Topical treatment of onychomycoses is time consuming, cost-intensive and subject to relatively high failure rates. Light-based devices may be effective treatment modalities. Aim of this work: To compare the clinical and mycological efficacy of Nd-YAG laser versus topical terbinafine in the treatment of onychomycosis., Patients and Methods: This study included 40 patients with onychomycosis randomized to receive four sessions of Nd-YAG laser (group A) or topical terbinafine twice daily for six months (group B). Follow-up was performed monthly. Mycological examination was done at third and sixth months following the start of treatment., Results: After six months, all patients in group A showed marked improvement, while in group B only 50% of patients showed mild to moderate improvement. In addition, by the end of six months, 80% of the patients in group A showed mycological clearance, while all patients in group B still had positive cultures., Conclusion: Long pulse Nd-YAG laser therapy of onychomycosis is a safe and efficient method for treating onychomycosis. It is especially beneficial in elderly, compromised and hepatopathic patients for whom other alternative treatments could present some risks.

Background: Adriamycin (ADR) is a potent chemotherapeutic agent widely used in the treatment of childhood acute lymphoblastic leukemia (ALL); its clinical use is limited owing to its marked cardiotoxicity. The present study investigated the possible protective role of carvedilol on ADR-induced left ventricular dysfunction in children with ALL., Methods and Results: Fifty children with newly diagnosed ALL were included in this study. They were divided into 2 equal groups: 1) ADR; and 2) ADR + carvedilol. Patients were evaluated with conventional 2-dimensional echocardiographic examination (2D), pulsed tissue Doppler (PTD), and 2-dimensional longitudinal strain echocardiography (2DS) before and after therapy. Plasma lactic dehydrogenase (LDH), creatine phosphokinase (CPK), and troponin I levels were also determined before and after therapy. ADR treatment reduced left ventricular systolic dysfunction as assessed by a significant decrease in fractional shortening (FS) (2D) and global peak-systolic strain (GPSS; 2DS). In addition, ADR treatment significantly increased plasma troponin I and LDH. Pretreatment of ADR-treated patients with carvedilol resulted in a significant increase in FS (2D) and GPSS (2DS). Furthermore, carvedilol pretreatment inhibited ADR-induced increase in plasma troponin I and LDH., Conclusions: These results suggested a protective role of carvedilol against ADR-induced cardiotoxicity., (Copyright © 2012 Elsevier Inc.
