Aim:The aim of the study was to evaluate the efficacy of platelet-rich plasma (PRP) in the treatment of chronic alopecia areata (AA).Material and Methods:This is a prospective study that was conducted at Kamal Hospital, Kaushambi in which 20 patients who attended the outpatient department were enrolled for the study. All the patients had h/o patches and taken various line of treatments for a duration of 2 years. All the patients were biopsy-proven positive for AA disease. There was no randomisation done since all of them were healthy young adults. The patients’age ranged from 25 to 35 years, and none of them had any co-morbidities.Results:Of 20 patients, only one patient had a relapse. None of the patients had any side effects, and all of them tolerated the procedure well.Conclusion:We wish to conclude that PRP has a definite role in treating AA infections. However, still more long-term follow-up, studies are required for further validation of results and labelling it as a 100% cure for people suffering from AA with recurrences which are so common.

The present manuscript represents an updated review on different aspects of immunology involved during hepatitis C virus infection in human beings. This includes a brief mention of HCV structure, presentation of viral components to host immune system, and ensuing immune response and immunopathogenesis occurring during HCV infection. The present article also highlights immunodiagnosis of HCV infection and the current status of immunotherapy available for HCV eradication. Its envelope protein, E2, is the primary mediator of virus attachment and cell entry. CD81 molecule on cell surface acts as a major receptor for viral entry into the host cells. Mature dendritic cells play an important role in presenting viral antigen, activate T-cells, and initiate anti-viral immune response. Relative T-cell populations and release of different cytokines from activated T-cells ultimately determine the clearance or persistence of HCV viremia through cellular and humoral immune responses. Natural killer (NK) cells constitute the first line of host defense against invading viruses by recruiting virus-specific T-cells and inducing antiviral immunity in liver. Diagnosis of acute or chronic hepatitis C virus (HCV) infection is established by serological assays for presence of antibodies against different sets of viral proteins during varied periods post infection. An effective immunotherapy and vaccine against HCV is still awaited.

Both dexmedetomidine and lidocaine were effective to blunt rise in HR, MAP and ICP in response to CP and TS in patients with sTBI. However, intravenous dexmedetomidine caused significant decrease in MAP and CPP as compared to the baseline and lidocaine.

Objective: Static monitors for assessing the fluid status during major surgeries and in critically ill patients have been gradually replaced by more accurate dynamic monitors in modern-day anaesthesia practice. Pulse pressure variation (PPV) and systolic pressure variation (SPV) are the two commonly used dynamic indices for assessing fluid responsiveness. Methods: In this prospective observational study, 50 patients undergoing major surgeries were monitored for PPV and SPV: after the induction of anaesthesia and after the administration of 500 mL of isotonic crystalloid bolus. Following the fluid bolus, patients with a cardiac output increase of more than 15% were classified as responders and those with an increase of less than 15% were classified as non-responders. Results: There were no significant differences in the heart rate (HR), mean arterial pressure (MAP), PPV, SVV, central venous pressure (CVP) and cardiac index (CI) between responders and non-responders. Before fluid bolus, the stroke volume was significantly lower in responders (p=0.030). After fluid bolus, MAP was significantly higher in responders but there were no significant changes in HR, CVP, CI, PPV and SVV. In both responders and non-responders, PPV strongly correlated with SVV before and after fluid bolus. Conclusion: Both PPV and SVV are useful to predict cardiac response to fluid loading. In both responders and non-responders, PPV has a greater association with fluid responsiveness than SVV. Keywords: Fluid management, pulse pressure variation, systolic pressure variation, fluid responsiveness Amaç: Günümüzde anestezi pratiğinde, büyük ameliyatlarda ve ağır hastalarda sıvı durumunun değerlendirilmesi için kullanılan statik izlem yöntemlerinin yerini, daha doğru sonuçlar veren dinamik izlemler almıştır. Nabız basıncı değişimi (PPV) ve sistolik basınç deği-şimi (SPV) sıvı yanıtını değerlendirmek amacıyla yaygın bir şekilde kullanılan dinamik indekslerdir. Yöntemler: Bu prospektif gözlemsel çalışmada, major cerrahi geçire-cek 50 hastada anestezi indüksiyonundan ve 500 mL izotonik verildikten sonra PPV ve SPV monitörize edildi. Bolus sıvı uygulamasını takiben, %15'ten fazla kardiyak debisi artışı olan hastalar yanıt verenler olarak, %15'ten daha az artışı olanlar ise yanıt vermeyenler olarak sınıflandırıldılar. Bulgular: Yanıt verenler ve vermeyenler arasında kalp atım hızı (HR), ortalama arter basıncı (MAP), PPV, SVV, santral venöz basınç (CVP) ve kardiyak indeks (CI) açısından anlamlı bir fark bulunmadı. Bolus sıvı uygulaması öncesinde, atım hacmi yanıt verenlerde anlamlı derecede daha düşüktü (p=0,030). Bolus sıvı uygulaması sonrasında, MAP yanıt verenlerde anlamlı ölçüde daha yüksek bulundu, ancak HR, CVP, CI, PPV ve SVV açısın-dan anlamlı fark gözlenmedi. Bolus sıvı uygulaması öncesinde ve sonrasında, hem yanıt veren hem de yanıt vermeyen hastalarda, PPV değeri ile SVV değeri arasında güçlü bir ilişki saptandı. Sonuç: PPV ve SVV sıvı yüklenmesine verilen kardiyak yanıtı tahmin etmede yararlıdır. Hem yanıt veren hem de vermeyen hastalarda ...

Facial fillers are minimally invasive aesthetic procedures performed for facial rejuvenation and contouring all over the world. Fillers even in the most experienced hands can lead to fatal complications such as vascular complications that need to be managed immediately with the help of hyaluronidase protocols mentioned in literature. In this case report, a patient was asymptomatic with no signs of vascular occlusion such as blanching or poor capillary refill for 48 h. He came after more than 48 h of the filler injection with complaints of pulsating pain in the right infraorbital and nasolabial area. We noticed necrosed microvesicles in the infraorbital artery territory with signs of impending skin necrosis extending from right infraorbital region up to the nasolabial fold (slightly medial to it). He was treated immediately with three pulsed doses of 500 units higher dilation of 10 ml each every hour (reconstitution carried out using 3mL normal saline). The skin color improved with decreased pain, and the next day (after 14 hours) we injected 500 units of hyaluronidase in higher dilution of 10mL as slight redness was still present. Skin redness, swelling, and pain disappeared the following day. Skin was completely healed and by 15 days we noticed slight post-inflammatory hyperpigmentation, which was easily managed with Q-switched laser and creams. We hereby report a case of delayed skin necrosis (>48 h) following filler injections in the cheek area, in the infraorbital artery vascular territory, which was successfully managed with pulsed dose of hyaluronidase.
