Outcomes with allogeneic hematopoietic stem cell transplantation in TP53-mutated myelodysplastic syndrome: A systematic review and meta-analysis.

We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in TP53-mutated myelodysplastic syndromes (MDS). A literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.gov. After screening 626 articles, eight studies were included. Data were extracted following the PRISMA guidelines and analyzed using the meta-package by Schwarzer et al. We analyzed 540 patients. The pooled median 3 (1-5) year overall survival was 21% (95% CI 0.08-0.37, I2=91%, n=540). The pooled relapse rate was 58.9% (95% CI 0.38-0.77, I2=93%, n=487) at a median of 1.75 (1-3) years. The pooled 4-year progression- free survival was 34.8% (95% CI 0.15-0.57, I2=72%, n=105). Outcomes of Allo-HSCT for TP53-mutated MDS patients remain poor, with 21% OS at three years; however, Allo-HSCT confers a survival advantage as compared to non-transplant palliative therapies. Our findings suggest the need to explore novel therapeutic agents in prospective clinical trials.

Outcomes with chimeric antigen receptor t-cell therapy in relapsed or refractory acute myeloid leukemia: a systematic review and meta-analysis.

Background: We conducted a systematic review and meta-analysis to evaluate outcomes following chimeric antigen receptor T cell (CAR-T) therapy in relapsed/refractory acute myeloid leukemia (RR-AML). Methods: We performed a literature search on PubMed, Cochrane Library, and Clinicaltrials.gov. After screening 677 manuscripts, 13 studies were included. Data was extracted following PRISMA guidelines. Pooled analysis was done using the meta-package by Schwarzer et al. Proportions with 95% confidence intervals (CI) were computed. Results: We analyzed 57 patients from 10 clinical trials and 3 case reports. The pooled complete and overall response rates were 49.5% (95% CI 0.18-0.81, I2 =65%) and 65.2% (95% CI 0.36-0.91, I2 =57%). The pooled incidence of cytokine release syndrome, immune-effector cell associated neurotoxicity syndrome, and graft-versus-host disease was estimated as 54.4% (95% CI 0.17-0.90, I2 =77%), 3.9% (95% CI 0.00-0.19, I2 =22%), and 1.6% (95%CI 0.00-0.21, I2 =33%), respectively. Conclusion: CAR-T therapy has demonstrated modest efficacy in RR-AML. Major challenges include heterogeneous disease biology, lack of a unique targetable antigen, and immune exhaustion.

Hearing loss: an unusual presentation of neurobrucellosis: a case report.

INTRODUCTION: Brucellosis is a zoonotic disease, caused by a Gram-negative coccobacillus of Brucella genus, transmitted to humans by animals, especially cattle. It rarely involves the nervous system (neurobrucellosis); only a few cases present with hearing loss. We report a case of neurobrucellosis, that presented with bilateral sensorineural hearing loss and mild to moderate persistent headache. To the best of our knowledge, this is the first well-documented case from Nepal. CASE PRESENTATION: The patient was a 40-year-old Asian male shepherd from the western mountainous region of Nepal who came to the emergency department of Manipal Teaching Hospital, Pokhara in May, 2018 and did a follow-up for 6 months. He presented with high-grade fever, profuse sweating, headache, myalgia, and bilateral sensorineural hearing loss. His history of consuming raw milk of cattle, symptoms including persistent mild to moderate headache, bilateral hearing loss, and serological findings were suggestive of neurobrucellosis. Following treatment, the symptoms improved, including the complete recovery of hearing loss. CONCLUSION: Hearing loss may be the manifestation of neurobrucellosis. Physicians should know about such presentations in brucella endemic areas.

Outcomes of Tyrosine Kinase Inhibitors Maintenance Therapy with or without Allogeneic Hematopoietic Stem Cell Transplantation in Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia in First Complete Remission: A Systematic Review and Meta-Analysis.

We conducted a systematic review and meta-analysis to compare outcomes of tyrosine kinase inhibitor (TKI) maintenance therapy with or without allogeneic hematopoietic stem cell transplantation (HSCT) in Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) in first remission (CR1). A literature search was performed on PubMed, Cochrane, and Clinical trials.gov. After screening 1720 articles, 12 studies were included. Proportions and odds ratios (OR) with 95% confidence intervals (CI) were computed. I2 provides an estimate of the percentage of variability in results across studies that is due to real differences and not due to chance. Of 1039 patients, 635 (61%) had TKI alone and 404 (39%) patients had HSCT followed by TKI. At 3 years, a trend towards poor overall survival (OS; OR 0.67, 95% CI 0.39-1.15, I2 = 68%), (disease-free survival; OR 0.58, 95% CI 0.26-1.29, I2 = 76%), and higher relapse rate (RR; OR = 2.52, 95% CI = 1.66-3.83, I2 = 26%) was seen with TKI alone compared to HSCT-TKI. Although HSCT followed by TKI maintenance in Ph+ ALL has long been considered standard of care, the introduction of potent third-generation TKIs and bispecific T-cell engagers such as Blinatumomab has significantly improved outcomes while sparing the need for HSCT in newly diagnosed patients.

Use of endpoints in phase III randomized controlled trials for acute myeloid leukemia over the last 15 years: a systematic review.

We systematically evaluated the primary and secondary endpoints used in acute myeloid leukemia (AML) phase III randomized controlled trials (RCTs). We included 238 phase III AML RCTs in the past 15 years that reported 279 primary endpoints and 657 secondary endpoints. Overall survival (OS), progression-free survival (PFS), event-free survival (EFS), and complete remission (CR) were primary endpoints in 120 (43%), 34 (12%), 30 (11%), and 41 (15%) studies, respectively. OS (12.5%), PFS (13.2%), CR (14%), safety (11%), and EFS (9%) were commonly reported secondary endpoints. Among primary endpoints, a higher use of OS (OR 2.03, 95%CI 1.10-3.75, p = 0.023) and lower use of PFS (OR 0.25, 95%CI 0.12-0.52, p < 0.001) was observed from 2014 to 2021 compared to 2006-2013; CR was frequently used in relapsed/refractory compared to frontline RCTs (OR 2.20, 95%CI 1.11-4.38, p = 0.025); EFS was frequently used in frontline compared to relapsed/refractory AML RCTs (OR 10.11, 95%CI 1.34-76.34, p = 0.025). A higher trend in the use of clinically meaningful and objective endpoint of OS over the last 15 years.

Sustained Inflammation of Breast Tumors after Needle Biopsy.

INTRODUCTION: Needle biopsy is essential for definitive diagnosis of breast malignancy. Significant histologic changes due to tissue damage have been reported in solid tumors. This study investigated the association between time from needle biopsy and inflammation in breast tumors. METHODS: A total of 73 stage I-II invasive breast cancer cases diagnosed by image-guided needle biopsy who had surgery as their first definitive treatment were retrospectively analyzed. Time from biopsy to surgical excision ranged from 8 to 252 days. Histological sections of surgically resected tumors with a visible needle tract were reviewed by histologic evaluation. Data were analyzed by McNemar's test for proportional differences, and the Benjamini-Hochberg procedure was used to assess the association between immune cell prevalence and clinical variables. RESULTS: Characteristic histology changes, including foreign body giant-cell reaction, synovial-cell metaplasia, desmoplastic repair changes, granulation tissue, fat necrosis, and inflammation, were frequently detected adjacent to the needle tract. Spatial comparison indicated that a higher proportion of cases had neutrophils, eosinophils, and macrophages adjacent to the needle tract than tumors distant from it. The presence of inflammatory cells adjacent to the needle tract was not associated with time from biopsy or subtype. Still, plasma cells were associated with residual carrier material from biopsy markers. CONCLUSION: Macrophages and eosinophils are highly abundant and retained adjacent to the needle tract regardless of time from the biopsy.

Outcomes with mismatched unrelated donor allogeneic hematopoietic stem cell transplantation in adults: A systematic review and meta-analysis.

Background: Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for various hematologic disorders. Alternative donor strategies such as mismatched unrelated donors (MMUD) offer the option of HSCT to patients lacking a human leukocyte antigen (HLA)-matched donor. We conducted a systematic review and meta-analysis to evaluate outcomes after MMUD-HSCT. Methods: A literature search was performed on PubMed, Cochrane Library, and ClinicalTrials.gov from the inception date through April 6, 2022. After screening 2477 manuscripts, 19 studies were included. Data was extracted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Pooled analysis was done using the meta-package by Schwarzer et al. Proportions with 95% confidence intervals (CI) were computed. Results: A total of 3336 patients from 19 studies were included. The median age was 52.1 years, and 53% of recipients were males. The graft source was bone marrow in 19% and peripheral blood stem cells in 81% of recipients. The median time to transplant from hematologic diagnosis was 10 (1-247) months. Hematologic diagnoses included myeloid (82.9%), lymphoid (41.1%), and other disorders (3%). The reduced intensity and myeloablative conditioning were used in 65.6% and 32% of recipients, respectively. In-vivo T-cell depletion was performed in 56.7% of the patients. Most patients had one (87.9%) or two (11.4%) antigen HLA-mismatch. The pooled 1-year overall survival (OS) was 63.9% (95% CI 0.57-0.71, n=1426/2706), and the pooled 3-year OS was 42.1% (95% CI 0.34.2-0.50, n=907/2355). The pooled progression-free survival was 46.6% (95% CI 0.39-0.55, n=1295/3253) after a median follow-up of 1.8 (range 1-6) years. The pooled relapse rate was 26.8% (95% CI 0.22-0.32, n=972/3253) after a median follow-up of 2.25 (1-3) years. The pooled incidence of acute (grade II-IV) graft-versus-host disease (GVHD) and chronic GVHD was 36.4% (95% CI 0.31-0.42, n=1131/3030) and 41.2% (95% CI 0.35-0.48, n=1337/3228), respectively. The pooled non-relapse mortality was 22.6% (95% CI 0.17-0.29, n=888/3196) after a median follow-up of 2.6 (1-5) years. Conclusion: MMUD-HSCT has demonstrated favorable outcomes with an acceptable toxicity profile. It represents a promising option in patients lacking an HLA-matched or haploidentical donor and may expand HSCT access to underrepresented racial and ethnic populations.

Outcomes with allogeneic hematopoietic stem cell transplantation in TP53-mutated acute myeloid leukemia: a systematic review and meta-analysis.

We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (HSCT) in TP53-mutated acute myeloid leukemia (AML). We performed a literature search on PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. After screening 592 manuscripts, eight studies were included. Data were extracted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Pooled analysis was done using the meta-package by Schwarzer et al. Proportions with 95% confidence intervals (CIs) were computed. We analyzed 297 patients. The median follow-up was 45 (0.9-407.3) months. The pooled 2-year overall survival was 29.7% (95% CI 0.17-0.43, n = 82/248). The pooled relapse rate was 61.4% (95% CI 0.41-0.79, n = 139/247) at a median follow-up time of 2 (0.26-3) years. Three-year progression-free survival and non-relapse mortality were reported by one study as 7.5% and 32.5%, respectively. Outcomes of HSCT for TP53-mutated AML are poor; however, HSCT confers a survival advantage as compared to non-transplant palliative therapies.

Acute Non-Traumatic Sub-Arachnoid Hemorrhage in a Young Female With Diabetic Ketoacidosis.

Diabetic ketoacidosis (DKA) is one of the most common causes of morbidity and mortality in patients with type 1 DM. Due to severe acidosis, ketonemia and electrolyte disturbances it can lead to various complications in the body, which can be fatal in some cases. Neurological complications related to DKA include cerebral edema, cerebral infarction, brain herniation, cortical venous thrombosis. It is very rare for DKA to cause subarachnoid hemorrhage (SAH). We present a case 19-year-old female with severe DKA, who developed SAH without any pre-existing aneurysm or other common risk factors. The patient did not have any neurologic deficits and was managed conservatively with the resolution of her symptoms. We have also summarized the existing literature regarding the association of DKA with subarachnoid hemorrhage.

The plight of COVID-19 pandemic on medical students and residency applicants.

In this pandemic situation, medical students find them in a state of apprehension. With medical institutions closed and switch to online teaching and telehealth, many aspects of medical learning are still compromised, including core clinical rotations, clinical skills evaluation, and exams cancelation. The medical students are distressed about their continuity of education and developing the necessary skill to feel confident enough to practice in the future. The involvement of medical students as frontline workers with inadequate clinical training, the uncertainty of future, lack of knowledge, and access to personal protective equipment have aroused a sense of fear in them. They not only nurture their clinical skills from the clinical rotations but it also helps adapt to their residency program later. With the lack of clinical experience, challenges of online learning, cancelation of conferences, and on-site research, medical students are struggling to make their residency application competitive. Recruiting residents amid the pandemic is a difficult task. The uncertainty in the unprecedented situation has an immense psychological impact on medical students and residency applicants. Despite the hurdles being faced, there are many ways where medical students and residency applicants can use their knowledge to help in fighting the pandemic. They can volunteer in the field of research on COVID-19, as a contact tracer, and provide peer support to the patients through telecommunications. Many avenues are being sought to ensure the continuation of medical education. However, how efficient these methods will prove in the future is yet to be revealed.

Renal Infiltration as a Primary Presentation of Burkitt Lymphoma Secondary to Systemic Lupus Erythematosus: A Rarity Unto a Rarity.

Burkitt lymphoma (BL) is a highly aggressive non-Hodgkin B-cell lymphoma characterized by the translocation and deregulation of the MYC (MyeloCytomatosis) gene on chromosome 8. Three distinct clinical forms of BL are recognized: endemic (African), sporadic (non-endemic), and immunodeficiency-associated. Bilateral renal infiltration leading to acute kidney injury (AKI) is a rare initial presentation of BL. Diagnosis is usually made after evaluating the histology and immunophenotyping of the affected tissue. We report a case of a 46-year-old male who presented with symptoms of AKI resulting from infiltrative disease, a primary presentation of lymphoma. The patient was a known case of systemic lupus erythematosus (SLE) for the last five years and was referred to the nephrology department due to acute elevation in creatinine, from 0.8 mg/dL to 3.57 mg/dL. On physical examination, there was no lymphadenopathy. Nephrology and SLE workup revealed low complement protein levels and absolute neutrophils, lymphocytes, and metamyelocytes. Renal ultrasound (USG) showed both kidneys with symmetric and edematous appearance. Biopsy affirmed high-grade B-cell lymphoma, positive for BCL-6 (B-cell leukemia/lymphoma) and CD-10 (cell surface marker) and negative for BCL-2 (B-cell leukemia/lymphoma). PET (positron emission tomography) scan showed extensive hypermetabolic lymphadenopathy in multiple areas. The patient was started on chemotherapy and on continuous renal replacement therapy. He improved clinically, and his creatinine lowered down to 0.8 mg/dL. Repeat USG showed decreased edematous appearance of both kidneys. Primary renal infiltration by BL is a rare presentation in adults. Prompt renal biopsy will change the course of treatment and can affect the prognosis. It is thoroughly advised to keep this malignancy in mind when making a diagnosis for AKI.

All-Cause Mortality Outcomes of Usage of Cardiac Contractility Modulation in Patients With Dilated Cardiomyopathy Ineligible for Cardiac Re-Synchronization Therapy: An Updated Meta-Analysis of Randomized Controlled Trials.

Introduction Dilated cardiomyopathy has been associated with remarkably high mortality despite guideline-directed therapy. This study compares the all-cause mortality rate between a cardiac contractility modulation group and a standard therapy group in patients with dilated cardiomyopathy who were monitored via follow-up for 12 weeks or more. Materials and methods We conducted a systematic search of Medline (PubMed) and Cochrane Central Register of Controlled Trials for abstracts and fully published studies (from inception to October 2018). We searched for articles comparing cardiac contractility modulation device therapy with standard therapy for patients with dilated cardiomyopathy between September 1, 2018, and October 30, 2018. Only fully published randomized clinical trials comparing all-cause mortality outcomes of device therapy and standard therapy for patients with dilated cardiomyopathy were included in our meta-analysis. A total of 673 studies were identified. Studies that were systematic reviews or meta-analyses, study designs or protocols, trials on other regimens, wherein medical therapy was not compared, or wherein the primary outcome of mortality was not assessed, were excluded. Data were abstracted by two independent reviewers. A random-effect model using the Mantel-Haenszel method calculated the weighted risk ratio (RR). Statistical analyses were performed using Review Manager 5.3 (The Nordic Cochrane Centre, The Cochrane Collaboration; Copenhagen). The primary outcome of interest was a comparison of all-cause mortality between the two groups when patients were monitored via follow-up for 12 weeks or more. Results Four fully published randomized clinical trials met the inclusion criteria of our analysis. A random-effect model using the Mantel-Haenszel method calculated the weighted RR. Our analysis included a total of 930 patients. The cardiac contractility modulation therapy group showed no significant reduction in all-cause mortality compared to the standard therapy group (RR, 0.63; 95% CI, 0.29-1.35; P = .23). However, the trend was toward device therapy. Tests for statistical heterogeneity did not show any significant heterogeneity (P = .82, I2 = 0%). Conclusions Cardiac contractility modulation device therapy is not associated with significant all-cause mortality reduction in patients with dilated cardiomyopathy. Our meta-analysis underscores the need for a large randomized controlled trial on the efficacy of cardiac contractility modulation in a population with dilated cardiomyopathy who are ineligible for cardiac resynchronization therapy.

Aortic Involvement in Antineutrophil Cytoplasmic Antibodies Vasculitis, a Coincidence or a Real Association?

Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is a type of small-vessel vasculitis. It is unusual for ANCA to involve aorta. However, multiple cases have been found where ANCA involved large vessels, particularly the aorta. Among vasculitides, aortic vasculitis is a part of Takayasu arteritis (TAK). In this review article, we tried to find the mechanism behind the aortic involvement in AAV. PubMed was used as a primary search engine, and all the available cases of aortic, as well as large-vessel involvement in ANCA-associated vasculitis, were thoroughly reviewed. Very limited data was available that could provide the mechanism behind this involvement. It is observed that ANCA-associated aortitis is more common in immunocompromised people; however, cases in previously healthy individuals have also been found. Pathogenesis of ANCA-related aortitis is different from Takayasu arteritis and is more close to ANCA-associated small vasculitis. ANCA-related aortitis involves the aorta through the same mechanism as it uses to involve small vessels. This rare manifestation of ANCA-associated vasculitis could be life-threatening but has a good prognosis if timely diagnosed and treated. ANCA-associated vasculitis must be considered as a differential diagnosis while treating a case of aortitis. We believe that there is a need to revise the classification of different types of vasculitides, and physicians should be aware of the possible overlap between different forms of vasculitides.

Role of Smoking in the Pathogenesis of Multiple Sclerosis: A Review Article.

Multiple sclerosis (MS) is a complex and unpredictable neurological condition. It is the most commonly seen autoimmune disorder. The incidence of disease and its prevalence are growing worldwide. Early identification of the disease and accurate diagnosis is important to prevent further complications and disability. The etiology remains unclear, and it is believed that complex gene-environment interactions play an essential role. Genetic predisposition only describes a portion of the disease risk, whereas lifestyle and environmental factors are significant contributors. Smoking was identified as an important risk factor for MS. The main objectives of this review were to examine the underlying mechanisms of immune dysregulation in the development of MS, explore the association between smoking and MS, and identify other genetic and environmental factors that alter the risk of developing the disease. We searched PubMed for articles relevant to the study topic published between 2000 and 2020 using the search terms "multiple sclerosis," "cigarette smoking," "risk factors," and, "epigenetics." Studies reveal a marked association between smoking and the risk of MS. Unlike genetic risk factors, many lifestyles and environmental factors can be adjusted, with potential for prevention, particularly for people at the highest risk, such as families of individuals with MS.

Urinary Tract Infection Caused by the Novel Pathogen, Lactococcus Garvieae: A Case Report.

Lactococcus garvieae is a part of the genus Lactococcus which was previously a part of the genus Streptococcus. It has been associated with serious diseases in aquaculture. However, human infections are rare. The most common presentation in humans is infective endocarditis. Urinary tract infection (UTI) is a unique presentation of this pathogen. We report the case of a 70-year-old male with a past history of benign prostatic hyperplasia who presented with confusion. Urinalysis confirmed the growth of L. garvieae. A seven-day treatment course of amoxicillin-clavulanate successfully treated the patient. The risk factors for acquiring the L. garvieae infections include contact with seafood or aquaculture. Other risk factors include immunosuppression, gastric acid suppression, and anatomical or physiological defect in the gastrointestinal tract. Special tests, such as VITEK® 2, API® 32 strep system, 16S rRNA, or polymerase chain reaction (PCR) testing, are needed for its diagnosis. Hence, we suggest underreporting of the infection may be possible. It is a novel cause of UTI, we suggest a high index of suspicion should be kept, especially in people with associated risk factors or exposure to seafood.

Long-Term Cardiovascular Diseases of Heatstroke: A Delayed Pathophysiology Outcome.

Heatstroke, defined as an elevated core body temperature above 40°C accompanied by altered mental status (e.g., confusion, disorientation, seizure and coma), is the most severe and life-threatening condition in the spectrum of heat-related illnesses. Heatstroke patients may present with multi-organ dysfunction, but with rapid cooling and organ failure management, a full recovery often occurs within weeks. Long-term impairment is rare, with neurological impairment occurring most frequently. Despite an abundance of research on the persistent neurological and hepatic impairments, our knowledge of the long-term cardiovascular events in patients with heatstroke history is poor. We wondered whether heatstroke leads to cardiovascular diseases long after full recovery. Using Pubmed, Web of Science and Scopus, we gathered cohort studies looking at cardiovascular disease incidence or mortality as an outcome, including heatstroke animal studies. Based on the available literature, we found that a history of heatstroke is associated with an increased risk of cardiovascular diseases, including ischemic heart disease, heart failure and atrial fibrillation. Delayed metabolic disturbances occurring in exertional heatstroke mice are linked to the formation of atherosclerosis and the development of heart failure. These processes provide potential pathophysiological pathways leading to ischemic heart disease and heart failure in heatstroke patients. Our findings may massively impact our understanding of heatstroke recovery and the follow up of heatstroke patients. Therefore larger, more adequately powered cohort studies with cardiovascular disease as an outcome, in tandem with animal studies examining the underlying pathophysiology, are required to confirm or reject these findings and answer the proposed questions.

Rheumatoid Vasculitis: Is It Always a Late Manifestation of Rheumatoid Arthritis?

Rheumatoid vasculitis (RV) is an infrequent complication of longstanding severe rheumatoid arthritis (RA). The active vasculitis associated with rheumatoid disease occurs in about 1%-5% of the patient population. RV is a manifestation of "extra-articular" rheumatoid arthritis and involves the small- and medium-sized arteries in the body. Newer RA treatments, including biologic therapies, offer a broader array of potential therapeutic options, although no controlled trials exist to guide treatment. In general, following tissue confirmation of the diagnosis, the severity of organ involvement and disease manifestations can guide treatment decisions. We want to alert clinicians of this unique yet severe complication of RA which has high morbidity and mortality. We describe a thought-provoking case of a 44-year-old male with past medical history (PMH) of hypertension who presented with over three-month history of lower extremity (LE) swelling, discoloration, and ulceration. Arthralgias with constitutional symptoms (fatigue, weight loss), large pericardial effusion, was found to have leukocytoclastic vasculitis along with rheumatoid factor (RF) >650, and anti-cyclic citrullinated peptide (anti-CCP) antibodies >300, low C4 and normal C3. Pericardial fluid appeared serous, exudative, showed histiocytes, multinucleated giant cells and necrotic debris consistent with rheumatoid effusion. Skin, right shin, punch biopsy showed epidermal necrosis from underlying occlusive vasculopathy. Skin, left lower back, punch biopsy showed focal leukocytoclastic vasculitis. The patient was started on high dose steroids with marked improvement in the symptoms, Rituximab was planned awaiting QuantiFERON to be negative. Pan-CT angiography of the whole body was negative for any vascular changes ruling out polyarteritis nodosa (PAN).

Primary Cutaneous Nocardiosis: A Rare Presentation of Nocardiosis.

Nocardia is an uncommon gram-positive, weakly acid-fast bacterium that causes systemic or localized suppurative disease in humans and animals. Nocardiosis is typically regarded as an opportunistic infection, but approximately one-third of the patients are immunocompetent. The most common presentation is pulmonary disease (39%) followed by systemic involvement, defined as involvement of more than two sites; cutaneous presentation constitutes only 8% of the cases. Nocardia is widely distributed geographically; however, in the US, it is mostly found in warm and dry areas of South West and South East. We present a perfect case of cutaneous nocardiosis of a 70-year-old male, who presented with a traumatic splinter injury, leading to pustules formation on the right index finger, along with erythema and induration of the right arm. The patient was empirically diagnosed and treated for cellulitis, with amoxicillin and clavulanic acid, resulting in deterioration of the wound. The patient underwent incision and drainage and wound culture grew nocardia. The index of suspicion should be kept in mind while treating infectious blisters which have failed outpatient cellulitis treatment, immunocompromised hosts, and in nocardia prevalent regions.

A not so happy ending: coital cephalgia resulting from an acute non-traumatic intraparenchymal haemorrhage in a female with no comorbidities.

A sexual headache or coital cephalgia is a headache associated with sexual activity and is a well-recognised condition. It is usually benign, primary and self-limiting. However, occasionally sexual headaches can result from more sinister causes. Intraparenchymal and subdural haemorrhages have been reported as secondary causes of sexual headaches. We present the case of a 61-year-old woman with no comorbidities who presented acutely with a sexual headache and vision loss, and was found to have an occipital and parietal intraparenchymal haemorrhage. She was normotensive and after extensive workup was found to have no predisposing condition for her haemorrhage. The patient had an uneventful recovery with physical rehabilitation and had regular follow-ups, with no residual weakness. She was in a completely normal state of health 1 year after her event, and continued to be off any medications.
