Cryptococcosis and Cryptococcal Meningitis: A Narrative Review and the Up-to-Date Management Approach

Cryptococcosis is a fungal infectious disease that enormously impacts human health worldwide. Cryptococcal meningitis is the most severe disease caused by the fungus Cryptococcus, and can lead to death, if left untreated. Many patients develop resistance and progress to death even after treatment. It requires a prolonged treatment course in people with AIDS. This narrative review provides an evidence-based summary of the current treatment modalities and future trial options, including newer ones, namely, 18B7, T-2307, VT-1598, AR12, manogepix, and miltefosine. This review also evaluated the management and empiric treatment of cryptococcus meningitis. The disease can easily evade diagnosis with subacute presentation. Despite the severity of the disease, treatment options for cryptococcosis remain limited, and more research is needed.

Role of Fecal Microbiota Transplantation in Managing Clostridium Difficile Infection and Inflammatory Bowel Disease: A Narrative Review

Fecal microbiota transplantation (FMT) has been emerging as an alternate treatment modality in the management of patients with dysbiosis by restoring abnormal gut microbiota composition through the transplantation of normal fecal microbiota from healthy donors. This technique has lately gained a lot of attention in the treatment of recurrent or refractory Clostridium difficile infection (CDI) owing to its high success rates combined with its favorable safety profile. FMT has also been attracting the interest of clinicians as a new treatment option for inflammatory bowel diseases (IBD). Here, we reviewed most of the recent advancements in the use of FMT for CDI as well as its use in the treatment of IBD.

Ceftriaxone-Induced Thrombotic Thrombocytopenic Purpura Treated Successfully With Plasmapheresis and Eculizumab: A Rare Case Report

Thrombotic Thrombocytopenic Purpura (TTP) is a subtype of thrombotic microangiopathy (TMA) resulting in thrombocytopenia, anemia, fever, renal and neurological deficits. Although many drugs have been associated with drug-induced TTP, ceftriaxone has never been reported. Our case reports a patient who was started on ceftriaxone and developed TTP. Peripheral smear showed schistocytes and thrombocytopenia. Surprisingly, antibody formation against the metalloproteinase (ADAMTS13) levels were low-normal. The patient was treated with plasmapheresis and eczulimab, leading to platelet recovery and symptom resolution. TTP is a rare disorder and can be acquired or idiopathic. TTP can be diagnosed with normal ADAMTS13 as well. Further research is required to assess the mechanism by which ceftriaxone causes TTP. Physicians should consider the possibility of TTP in patients with similar presentations following ceftriaxone therapy and use it for timely diagnosis and treatment. Early diagnosis and treatment of ceftriaxone-induced TTP can prevent devastating consequences.

A Textbook Case of Human T-lymphotropic Virus-1 (HTLV-1)-Induced Adult T-cell Leukemia Treated With Cyclophosphamide, Hydroxydaunorubicin, Oncovin, and Prednisone/Prednisolone (CHOP)

Human T-lymphotropic virus-1 (HTLV-I) is an enveloped, single-stranded RNA virus of the Retroviridae family. The virus causes two well-recognized disease associations: adult T-cell leukemia/lymphoma (ATL) and HTLV-I-associated myelopathy (HAM), also known as tropical spastic paraparesis (TSP). We report a case of HTLV-1-induced adult T-cell lymphoma/leukemia in a 45-year-old female who presented with complaints of swelling on the right side of her neck and rash on her upper and lower extremities and abdomen. The patient also had a history of strongyloidiasis infection and Crohn's disease. She was found to have hypercalcemia and multiple lytic lesions of the bone found on the imaging. She also tested positive for HTLV-1 and T cell-positive for cluster of differentiation (CD) 2, CD3, partial CD5, and minimal CD56, later confirmed by the bone marrow (BM) and skin punch biopsies. ATL is characterized by the clonal proliferation of CD4+ T cells containing randomly integrated HTLV-I provirus, often associated with T-cell receptor gene rearrangements. ATL, in its aggressive forms, has one of the poorest prognoses of non-Hodgkin lymphoma. It is essential to raise awareness of ATL, although further research and trials are needed to solidify the treatment options to prevent mortality.

Necrotizing Autoimmune Myopathy: A Case Report on Statin-Induced Rhabdomyolysis

Statin-induced necrotizing myopathy (SINM) is an uncommon but severe complication associated with statin medication. SINM can develop at any point after a person starts taking steroids. It is now being acknowledged as a component of the broader category of "statin-induced myopathy." Like other immune-mediated necrotizing muscle diseases, statin-induced myositis is identified by weakness in proximal muscles, increased serum creatine kinase (CK) levels, and, in some cases, dysphagia and respiratory distress. In addition, there is evidence of muscle cell damage when examined under a microscope, occurring with minimal or no infiltration of inflammatory cells. Diagnosing SINM promptly is frequently challenging due to its unpredictable development over time, with symptoms sometimes emerging many years after the initial exposure to statins. One distinctive characteristic of SINM is the continued presence of muscle inflammation and elevated CK levels even after discontinuing statin treatment. Currently, no clinical trials are available to guide how to manage statin-induced immune-mediated necrotizing myopathy (IMNM). Here, we present a case of a 42-year-old woman diagnosed with SINM and was found to have persistently elevated CPK despite discontinuation of statins. Our case also suggests that intravenous (IV) immunoglobins and steroids are an effective and well-tolerated alternative to immunosuppressants.

Clinical Conundrum of Acute Hepatitis B With Concurrent Hepatitis E Infection Leading to Severe Acute Liver Injury

Acute liver injury in the setting of acute fulminant hepatitis caused by the hepatitis B virus (HBV) can occur both during primary infection and after chronic HBV reactivation. Guidelines recommend considering antiviral therapy in both cases. Antiviral therapy with a nucleoside analog may be beneficial in patients with acute liver failure from acute HBV infection, though not all studies have shown a benefit. This is a case of a 53-year-old woman with a past medical history of untreated hepatitis C with undetectable viral load and right breast cancer status post lumpectomy, who presented to the emergency department with complaints of yellowish skin and sclera discoloration with right upper quadrant pain for one week. She was a known intravenous drug abuser and binge alcohol user. Her labs were positive for hepatitis B, hepatitis E, and hepatitis C viruses. She also had elevated liver enzymes with hyperbilirubinemia showing severe acute liver injury. Computed tomography of the abdomen and pelvis with contrast was normal, and the abdominal ultrasound showed homogenous echotexture of the liver without a focal lesion. The patient was diagnosed with acute fulminant hepatitis B. After initial hemodynamic stabilization, N-acetylcysteine (NAC) and tenofovir were started, and transaminases were followed. Liver function tests showed a downtrend, and, in a few weeks, they came to baseline. Hepatitis B viral load became undetectable as well. Acute hepatitis B infection is seldom treated. The presented case depicts the use of tenofovir in the setting of severe acute liver injury due to hepatitis B. Starting antiviral therapy (especially tenofovir disoproxil fumarate) early in the disease course was shown to have very assuring results with complete resolution of symptoms and normalization of liver function tests. The treatment protocol for acute HBV deserves further investigation.

Hashimoto's Thyroiditis Encephalopathy Induced by COVID-19 Infection

Various factors can lead to thyroiditis, including any acute inflammatory process, especially viral illness. While coronavirus disease 2019 (COVID-19) has been linked to disorders of various systems, there is a lack of literature showing an association of coronavirus with the cause of Hashimoto's thyroiditis. Several possible mechanisms for this outcome have been proposed; chief among them is molecular mimicry. Here, we are reporting a case of Hashimoto's thyroiditis incited by COVID-19 in a 34-year-old obese female who presented with anxiety, behavioral changes, and repeated head movements. The patient had an elevated thyroid stimulating hormone (TSH) level, a low thyroxine (T4) level, and a positive anti-microsomal antibody screen. The patient also tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. Ultrasound of the patient's neck showed an enlarged heterogeneous thyroid gland. Thyroid replacement therapy with intravenous levothyroxine was started with the subsequent oral transition. Concurrently, she received antibiotics, steroids, and low-molecular-weight heparin for COVID-19. The patient exhibited significant improvement in her mental status, with an eventual return to baseline. The results of the thyroid panel obtained at the outpatient follow-up were normal. Although there is a paucity of data to show COVID-19 as a cause of this painless thyroiditis, this case demonstrates such causality between these two.

A Case Report of Wernicke’s Encephalopathy Disguised As Limbic Encephalitis: A Clinical Puzzle

Wernicke's encephalopathy (WE) is the presence of neurological symptoms in the central nervous system caused by thiamine (Vitamin B1) deficiency. It is an acute clinical condition characterized by confusion, ataxia, and ophthalmoplegia triad. WE is most commonly observed in chronic alcohol users, while it can also present in non-alcoholics. We present a 33-year-old man with alcohol-induced WE who presented with altered mental status and fever. His initial diagnosis was skewed towards bacterial meningitis and limbic encephalitis, but MRI findings were consistent with WE. The patient responded promptly to intravenous (IV) thiamine infusion, and his mental status changed significantly. Repeat EEG in 15 days shows complete recovery with normal brain wave activity. Untreated WE is a significant cause of permanent neurological morbidity and mortality, easily preventable. High suspicion of WE should always be entertained, especially when patients have a known history of alcohol use. Early initiation of IV thiamine could prevent the consequences. Hence, it is essential to raise awareness of WE to take measures without delay and reduce mortality and morbidity with an improved prognosis.

Ophthalmoparesis and Bilateral Ptosis as a Rare Manifestation of Todd's Phenomenon: Case Report and Review

Todd's paresis or phenomenon (TP) is a focal weakness in a part of the body after a seizure. Seizure is an abrupt change in behavior caused by the cerebral cortex's electrical hyper-synchronization of neuronal networks. After the seizure, there is usually a transition period from the ictal state to the pre-seizure baseline level of awareness and function, referred to as the postictal period. Postictal symptoms include many systems, including sensory, motor, and psychosis. This phenomenon is named after Robert Bentley Todd, who first described it. Todd's paresis can be confused with other conditions, most commonly a stroke. Postictal ocular manifestation may be accompanied by aphasia or hemiplegia, but isolated gaze palsy is rarely reported. We are reporting a rare and first known isolated ophthalmoparesis and ptosis as postictal findings with no structural abnormalities present in imaging studies and complete resolution over three weeks on its own as an atypical postictal phenomenon. Patients with an underlying structural abnormality of the brain are more susceptible to Todd's phenomenon. Unusual manifestations of Todd's phenomenon are rare but clinically relevant and are decisive in therapeutic decision-making. Our patient presents a rare manifestation of Todd's phenomenon as ptosis and ophthalmoparesis in an elderly male with no underlying structural brain abnormalities that resolved within three weeks. Further research into the causes is needed to distinguish it from a stroke

Furosemide-Induced Thrombotic Thrombocytopenic Purpura: A Report of a Rare Case

Drug-induced immune thrombocytopenia (DITP) refers to drug-dependent, antibody-mediated platelet destruction. Although several drugs have been implicated as the cause of DITP, the most commonly encountered are heparin, sulfonamides, quinine, vancomycin, and beta-lactam antibiotics. However, furosemide has been rarely reported as the cause of thrombocytopenia. We present a unique case of furosemide-induced thrombotic thrombocytopenia in a 64-year-old female referred by her primary care provider for low platelets, rash, and bleeding. She was recently started on oral furosemide for diastolic heart failure two weeks before this presentation. She was admitted to the intensive care unit and was worked up for new-onset thrombocytopenia. Labs revealed anemia, thrombocytopenia, elevated lactate dehydrogenase, and low haptoglobin with normal serum creatinine. Peripheral smear showed schistocytes, low platelets, and ADAMTS13 level was 0.03. The patient was diagnosed with thrombotic thrombocytopenic purpura and treated with steroids, rituximab, and plasmapheresis, which led to rapid recovery of the platelet count to normal. Based on this case report, clinicians should consider furosemide as one of the drugs potentially causing thrombotic thrombocytopenia. Early detection and prompt management can be lifesaving.

Mitomycin-Induced Thrombotic Thrombocytopenic Purpura Treated Successfully With Plasmapheresis and Steroid: A Case Report

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy (TMA) caused by severely reduced ADAMTS13 or the von Willebrand factor-cleaving protease (VWFCP) enzyme resulting in low platelet and red blood cell counts along with severe renal, cardiac, and neurological dysfunction. Plasmapheresis is the treatment of choice. Mitomycin, a widely used chemotherapeutic agent for gastrointestinal (GI) cancers anal and breast cancers, has been reported to occasionally cause severe TTP and hemolytic uremic syndrome (HUS) cases. Here, we present a case of a 57-year-old African American transgender patient who presented with worsening kidney function, thrombocytopenia, and anemia following mitomycin therapy for her anal squamous cell carcinoma. Peripheral smear showed numerous schistocytes, and the patient was diagnosed with TTP because of low ADAMTS13 levels. The patient was started on plasmapheresis and steroid with ultimate improvement in condition. TTP is a rare condition that can be idiopathic or acquired. Further research is required to assess the complexity of the underlying mechanism. Early diagnosis and aggressive management often lead to a favorable outcome.

Percutaneous Tracheostomy: A Bedside Procedure

Percutaneous tracheostomy is a bedside surgical procedure that creates an opening in the anterior tracheal wall. Tracheostomy is performed in patients expected to require mechanical ventilation for longer than seven to 10 days. This bedside percutaneous tracheostomy has been used since the late 1990s. Tracheotomy tubes are of various kinds like cuffed vs. uncuffed, fenestrated vs. unfenestrated, single lumen vs. double lumen, and metal vs. plastic. Its indications are categorized into emergency vs. elective. The most common emergency indication is acute airway obstruction, and the elective indication is prolonged intubation. There is no absolute contraindication, but a physician should consider severe hypoxia requiring high oxygen and coagulopathy. Percutaneous tracheostomy is a new technique requiring different skills. Advantages of percutaneous tracheostomy are as follows - it is performed at the bedside, procedural time is less, the cost is less, does not need operating schedule time. Percutaneous tracheostomy is generally performed by otolaryngologists, general surgeons, interventional pulmonologists, thoracic surgeons, or intensivists.

Clinical characteristics of bacteraemia caused by extended-spectrum β-lactamase-producing Enterobacteriaceae in the era of CTX-M-type and KPC-type β-lactamases

Clin Microbiol Infect 2012; 18: 887-893 ABSTRACT: A multicentre, case-control study was conducted to assess risk factors and patient outcomes of bacteraemia caused by Enterobacteriaceae producing extended-spectrum β-lactamases (ESBLs) and Klebsiella pneumoniae carbapenemases (KPCs). One hundred and five and 20 patients with bacteraemia caused by ESBL-producing and KPC-producing organisms were matched to controls who had bacteraemia caused by non-ESBL/KPC-producing organisms, respectively. Independent risk factors for ESBL production included admission from a nursing home (OR 4.64; 95% CI 2.64-8.16), chronic renal failure (OR 2.09; 95% CI 1.11-3.92), the presence of a gastrostomy tube (OR 3.36; 95% CI 1.38-8.18), length of hospital stay before infection (OR 1.02; 95% CI 1.01-1.03), transplant receipt (OR 2.48; 95% CI 1.24-4.95), and receipt of antibiotics with Gram-negative activity in the preceding 30 days (OR 1.76; 95% CI 1.00-3.08). Twenty-eight-day crude mortality rates for patients infected with ESBL-producing or KPC-producing organisms and controls were 29.1% (34/117) and 19.5% (53/272), respectively (OR 1.70; 95% CI 1.04-2.80). On multivariate analysis, inadequate empirical therapy (OR 2.26; 95% CI 1.18-4.34), onset of bacteraemia while in the intensive-care unit (OR 2.74; 95% CI 1.47-5.11), Apache II score (OR 1.17; 95% CI 1.12-1.23) and malignancy (OR 2.66; 95% CI 1.31-5.41) were independent risk factors for mortality. CTX-M was the most common ESBL type in Escherichia coli, whereas SHV predominated in Klebsiella spp. and Enterobacter spp.

Extended-spectrum and CMY-type beta-lactamase-producing Escherichia coli in clinical samples and retail meat from Pittsburgh, USA and Seville, Spain

Infections due to Escherichia coli producing extended-spectrum beta-lactamase (ESBL) or CMY-type beta-lactamase (CMY) are increasingly observed in non-hospitalized patients. The origin of these organisms is uncertain, but retail meat contaminated with E. coli may be a source. In the present study, clinical information and strains collected from patients infected or colonized with ESBL-producing and CMY-producing E. coli at hospitals in Pittsburgh, USA and Seville, Spain were investigated. Retail meat purchased in these cities was also studied for the presence of these organisms. Twenty-five and 79 clinical cases with ESBL-producing E. coli and 22 cases and one case with CMY-producing E. coli were identified in Pittsburgh and Seville, respectively. Among them all, community-acquired and healthcare-associated cases together constituted 60% of the cases in Pittsburgh and 73% in Seville. Community-acquired cases were more common in Seville than in Pittsburgh (49% vs. 13%; p <0.001). ESBL-producing and CMY-producing E. coli isolates were commonly recovered from the local retail meat. In particular, 67% (8/12) of retail chickens in Seville and 85% (17/20) of those in Pittsburgh contained ESBL-producing and CMY-producing E. coli isolates, respectively. Among the ESBL-producing isolates, CTX-M and SHV were the most common ESBL types in both clinical and meat isolates. Approximately half of the ESBL-producing and CMY-producing E. coli isolates from meat belonged to phylogenetic groups associated with virulent extra-intestinal infections in humans. Community and healthcare environments are now significant reservoirs of ESBL-producing and CMY-producing E. coli. Retail meat is a potential source of these organisms.

Pseudomonas aeruginosa bacteremia over a 10-year period: multidrug resistance and outcomes in transplant recipients

AIM

Transplant recipients are at risk for hospital-acquired infections (HAIs), including those caused by Pseudomonas aeruginosa. Of all HAIs, bloodstream infection (BSI) remains one of the most life-threatening.

METHODS

Over a 10-year period, we studied 503 patients, including 149 transplant recipients, with pseudomonal BSI from the University of Pittsburgh Medical Center. Trends in antimicrobial susceptibility, risk factors for multidrug resistance (MDR), and outcomes were compared between transplant and non-transplant patients.

RESULTS

Resistance to all antibiotic classes was significantly greater in pseudomonal blood culture isolates from transplant compared with non-transplant patients (P<0.001). Of isolates from transplant recipients (n=207), 43% were MDR, compared with 18% of isolates from non-transplant patients (n=391) (odds ratio [OR] 3.47; 95% confidence interval [CI] 2.34-5.14, P<0.001). Among all patients, independent risk factors for MDR P. aeruginosa BSI included previous transplantation (OR 2.38; 95% CI 1.51-3.76, P<0.001), hospital-acquired BSI (OR 2.41; 95% CI 1.39-4.18, P=0.002), and prior intensive care unit (ICU) admission (OR 2.04; 95% CI 1.15-3.63, P=0.015). Mortality among transplant recipients was 42%, compared with 32% in non-transplant patients (OR 1.55; 95% CI 0.87-2.76, P=0.108). For transplant recipients, onset of BSI in the ICU was the only independent predictor of mortality (OR 8.00; 95% CI 1.71-37.42, P=0.008).

CONCLUSIONS

Transplant recipients are at greater risk of MDR P. aeruginosa BSI, with an appreciable mortality. Future management must concentrate on the implementation of effective preventative strategies.

Management of psoriasis vulgaris with methotrexate 0.25% in a hydrophilic gel: a placebo-controlled, double-blind study

BACKGROUND

Methotrexate has been used as one of the first and systemic therapies for psoriasis. In general, 70% of patients with psoriasis prefer topical therapy as the treatment of choice.

OBJECTIVE

The purpose of this placebo-controlled double-blind study was to evaluate the clinical efficacy and tolerability of methotrexate 0.25% incorporated in a hydrophilic gel (hydroxyethylcellulose 1%) to treat patients afflicted with psoriasis vulgaris.

METHODS

Sixty patients (37M/23F) ranging between 18 and 70 years of age, with slight to moderate chronic plaque-type psoriasis and PASI (Psoriasis Area and Severity Index) scores between 5.3 and 17.5 joined the study. The mean duration of the disease at entry was 9.6 years (range 1-24 years). The diagnosis of psoriasis was established by clinical and histopathologic methods. Patients were sequentially randomized into two parallel groups. Each patient was allocated a precoded 100-g tube (active or placebo) with instructions on how to self-administer the trial medication topically (without occlusion) to their lesions two times daily for 5 consecutive days per week. The study lasted for 12 weeks with 4 weeks of active treatment. Patients were examined on a weekly basis and those showing total clearing or remission of lesions were considered effectively treated.

RESULTS

By the end of the treatment, breaking the code disclosed that methotrexate 0.25% gel had significantly treated more patients than placebo (83.3% vs. 6.7%; p < 0.0001), reduced the PASI score to a mean of 2.2, and cleared more plaques (82.2% vs. 4.3%; p < 0.0001). Laboratory evaluations, including CBC with differential and platelet count, renal function, liver chemistry [SGOT (aspartate transaminase) and SGPT (alanine transaminase)], and serum creatinine, were within the normal limits. The treatment was well-tolerated by all the patients, with no adverse drug-related symptoms and no dropouts. The study was followed up for 12 months from the first day of the treatment; two cured patients had relapsed after 8 months.

CONCLUSION

The findings of this study demonstrate that methotrexate 0.25% in a hydrophilic gel is well tolerated and significantly more effective than placebo as a patient-applied topical medication to treat psoriasis vulgaris.

Treatment of external genital warts in men with imiquimod 2% in cream. A placebo-controlled, double-blind study

OBJECTIVE

The purpose of this double-blind, placebo-controlled study was to evaluate the safety, clinical efficacy and tolerability of imiquimod (2%) in cream to cure external genital warts in males.

METHODS

Preselected male patients (n=60) ranging between 18 and 50 years of age (mean 24.2) harbouring 558 lesions (mean 9.3) with clinical, histopathological and polymerase chain reaction (PCR) confirmed diagnosis of human papilloma virus (HPV) infection were randomized to two parallel groups. Each patient was allocated a precoded 25g tube, and instructions on how to apply the trial medication to their lesions at home once daily for three consecutive days per week (max. 12 application in 4 weeks). To evaluate the safety, clinical efficacy and tolerance, patients were exa-mined on a weekly basis. Cure was defined as the total elimination of treated warts with PCR, and Southern blot hybridization confirmed negative HPV DNA.

RESULTS

By the end of the treatment, 40% (24/60) patients and 49.8% (278/558) warts were cured. Breaking the code revealed that imiquimod cream had cured 70% (21/30) patients and 86.8% of warts, while placebo healed three subjects and 28 warts (P=0.0001). Eleven patients (18.3%), predominantly in the imiquimod cream group, experienced mild to moderate, non-objective, drug-related side effects with no dropouts. The study was followed up for 18 months from the first day of the treatment, and among the 26 cured patients, one in the imiquimod cream group and two in the placebo had a relapse after 14 months.

CONCLUSION

The study demonstrated that 2% imiquimod in cream with mild non-objective side effects is safe, tolerable and significantly more effective than placebo in curing external genital warts in males.

Management of intravaginal warts in women with 5-fluorouracil (1%) in vaginal hydrophilic gel: a placebo-controlled double-blind study

The purpose of this placebo-controlled, double-blind study was to determine the safety, tolerability and clinical efficacy of 5-fluorouracil (1%) in a vaginal hydrophilic gel (hydroxyethylcellulose, 1%) to cure intravaginal papillomas in women. Pre-selected, 60 women ranging between 18 and 50 years of age (mean 24.6), having 312 vaginal condylomas (mean 5.2) joined the study. The diagnosis of human papillomavirus (HPV) was established with clinical, histopathological and polymerase chain reaction (PCR) techniques. Subjects were randomized into 2 parallel groups. Each patient was allocated a pre-coded tube 15 g (active or placebo) with graduated vaginal applicators (disposable), and instructions how to insert 4 g of the trial medication deep into the vagina once at bedtime on every other day (1, 3 and 5) per week, to visit the clinic on day 7 for clinical evaluations and to receive the same pre-coded replacement to continue the regimen for another week. A maximum 12 applications were to be used in 4 weeks. Cure was defined as absence of clinical signs of infection, re-confirmed by PCR and Southern blot hybridization negative HPV DNA. By the end of the treatment 48.4% patients and 51.9% lesions were cured. Breaking the code revealed that 5-fluorouracil (1%) gel had cured 83.3% patients and 87% intravaginal warts. Placebo resolved 13.3% patients and 14% condylomas; (active gel versus placebo; P < 0.001). Twelve patients (20%) mostly in the active gel experienced mild erythema, erosion and oedema, with no drop-outs. Among cured patients 3 had a relapse after 16 months. In conclusion, the clinical results of the study demonstrate that 5-fluorouracil (1%) in a vaginal hydrophilic gel is safe, tolerable and significantly more effective than placebo to cure intravaginal warts in women.

Treatment of toenail onychomycosis with 2% butenafine and 5% Melaleuca alternifolia (tea tree) oil in cream

The prevalence of onychomycosis, a superficial fungal infection that destroys the entire nail unit, is rising, with no satisfactory cure. The objective of this randomized, double-blind, placebo-controlled study was to examine the clinical efficacy and tolerability of 2% butenafine hydrochloride and 5% Melaleuca alternifolia oil incorporated in a cream to manage toenail onychomycosis in a cohort. Sixty outpatients (39 M, 21 F) aged 18-80 years (mean 29.6) with 6-36 months duration of disease were randomized to two groups (40 and 20), active and placebo. After 16 weeks, 80% of patients using medicated cream were cured, as opposed to none in the placebo group. Four patients in the active treatment group experienced subjective mild inflammation without discontinuing treatment. During follow-up, no relapse occurred in cured patients and no improvement was seen in medication-resistant and placebo participants.
