Raynaud's phenomenon associated with psoriatic arthritis.

We report a case of Raynaud's phenomenon in a patient with psoriatic arthritis (PsA). A middle-aged right-handed housewife presented with complaints of severely painful hand discolouration for 1 week, which usually worsened with cold exposure. She was diagnosed with PsA 6 months earlier. Her PsA was well controlled with weekly methotrexate. Physical examination showed no features of scleroderma or skin necrosis of her right hand. Both radial pulses were strong and symmetrical. Her nailfolds were visibly normal. The extractable nuclear antigen panel and other blood investigations were negative for scleroderma and other possible causes of secondary Raynaud's phenomenon. Occupational or environmental factors were also excluded. Dermatoscope examination of the nailfolds revealed some areas of dilated capillary loops, areas of vascular sparing and proximal nail fold telangiectasia. The diagnosis of secondary Raynaud's phenomenon was made, and an oral calcium channel blocker was started. The patient had significant improvement in symptoms shortly afterwards.

Severe cutaneous adverse reaction to drug excipient following brand-to-generic switch of levetiracetam.

PURPOSE: Levetiracetam is an antiepileptic drug known for its high tolerability, and severe adverse drug reactions are rare. We report the case of a severe cutaneous adverse drug reaction in a patient who was switched from brand-name to generic levetiracetam. SUMMARY: A 29-year-old woman undergoing contrast-enhanced computed tomography developed lesions over her trunk starting 6 hours after imaging. Although initially diagnosed as an allergy to the radiocontrast agent, the condition progressively worsened into toxic epidermal necrolysis-drug reaction with eosinophilia and systemic symptoms overlap syndrome, despite adequate hydration and treatment. Investigation of the patient's medications revealed that she had been switched from brand-name to generic levetiracetam a week before the onset of symptoms. Levetiracetam was immediately discontinued, with the patient recovering after 2 weeks of intensive care. Adverse drug reaction analysis identified excipients in generic levetiracetam as the likely cause of the severe reaction. CONCLUSION: This is the first reported case of severe cutaneous drug allergy after a brand-to-generic switch for levetiracetam. Brand-to-generic switches of medications can potentially cause severe allergic reactions due to differences in excipients.

Clinical profiles and predictors of survival in severe dengue cases.

Introduction: Dengue is endemic in tropical countries. Severe dengue has a high risk of morbidity and mortality. We aimed to identify factors associated with dengue survival among our intensive care unit (ICU) patients. Methods: A retrospective study was conducted among dengue cases admitted to the ICU of Hospital Sultan Abdul Halim, Kedah, Malaysia from 2016 to 2019. Results: Out of 1,852 dengue cases admitted to the hospital, 7.2% of patients required ICU admission. Survival rate was 88.6% among severe dengue cases. The majority of severe dengue patients were obese, while other notable comorbidities included hypertension and diabetes mellitus. Also, 73% of patients presented in the critical phase, at a median of Day 4 of illness. All patients admitted to the ICU had a history of fever. The predominant warning signs were lethargy, fluid accumulation and haemoconcentration with rapid platelet reduction. Among nonsurvivors, 69.2% had fulminant hepatitis, 53.8% had massive bleeding or disseminated intravascular coagulation, 38.5% had haemophagocytic lymphohistiocytosis and 30.8% had myocarditis. The predominant serotypes were DENV-3 and DENV-1. The least number of cases was seen in 2017, when all serotypes were equally presented. Multiple logistic regression showed that Sequential Organ Failure Assessment (SOFA) score, peak international normalised ratio, peak partial thromboplastin time and aspartate aminotransferase on admission were independent risk factors for survival. This model had an area under the curve of 0.98, giving an overall 98.2% accuracy. Conclusions: Specific warning signs and blood investigations in dengue patients may aid in early decision for ICU admission. Monitoring of SOFA scores plus coagulation and liver enzyme profiles could improve dengue survival rates.

Reuse of dialysis reverse osmosis reject water for aquaponics and horticulture.

BACKGROUND: Water crisis is becoming a threat to the well-being of the human population worldwide and use of water for healthcare contributes substantially to this resource depletion. Hemodialysis consumes large quantities of water. A huge volume of high purity dialysis water is required to safely perform dialysis treatment. In this process, up to 60-70% of source water is discarded. Many strategies have been suggested to promote green dialysis, and these include reuse of water, however, very few dialysis facilities have taken the preliminary steps to employ it. METHODS: We share our experience in a developing country on an innovative reject-water reuse program combining aquaculture, hydroponic and horticulture activities. This is by far the first report on a "green dialysis" project involving aquaponics that reuse dialysis reverse osmosis (RO) reject water. RESULTS: Our expereince suggests that reject water can be reused to promote water conservation with encouraging results. It provides a good and biosecure environment for fish breeding and vegetable farming . This project promotes a reduction in carbon footprint, a reduction in water waste, a sustainable organic food source, may lead to income generation, and provides a shared purpose and sense of pride among staff and dialysis patients. CONCLUSIONS: Encompassing "environmental protection" practices into a hemodialysis unit can be done with relatively simple and practical steps.

A Malaysian ex-smoker with cough, breathlessness and nonresolving bronchospasm.

Repeated noisy breathing may be a tricky feature of lung infection. Recognising classical features in radiographs and CT scans may help in the diagnosis of severe lung infection and the start of life-saving treatment. http://bit.ly/2lQwe5y.

Recombinant activated factor VII (rFVIIa) in refractory haemorrhage for non-haemophiliacs: an eleven-year single-centre experience.

BACKGROUND: Massive bleeding is one of the commonest salvageable causes of death. The search for an ideal haemostatic agent during massive bleeding is still ongoing. One of the novel haemostatic medications is recombinant activated factor VII (rFVIIa). To date, the usage of rFVIIa during massive haemorrhage among non-haemophiliac patients remains off-label. The aim of this study is to report our experience in using rFVIIa to treat refractory bleeding. METHODS: Medical records of all patients treated with rFVIIa for massive bleeding over an eleven-year period in a single institution were recorded. Treatment indications, 24-h and 30-day mortality, changes in transfusion needs and coagulation profiles after rFVIIa administration were analysed. RESULTS: rFVIIa were administered in 76 patients. Of these, 41 (53.9%) were non-surgical bleeding, followed by 22 patients (28.9%) with trauma, other surgery bleedings in 9 patients (11.8%) and 4 patients (5.4%) with peripartum haemorrhage. Total survival rate was 78.9% within 24 h and 44.7% over 30 days. Among all these patients who had received rFVIIa due to life-threatening haemorrhage, blood and blood product requirements were significantly reduced (P < 0.001), and the coagulation profiles improved significantly (P < 0.05). Two patients with preexisting thromboembolism were given rFVIIa due to intractable bleeding, both survived. No thromboembolic events were reported after the administration of rFVIIa. CONCLUSIONS: rFVIIa significantly improved coagulation parameters and reduced blood product requirements during refractory haemorrhage. Additionally, usage of rFVIIa in trauma and peripartum haemorrhage patients yield better outcomes than other groups of patients. However, the overall mortality rate remained high.

Masking and misleading: concomitant actinomycosis and B-cell lymphoma - a case report and review of literature.

We report a 72-year-old patient who presented with an ulcerated palatal mass, weight loss and adrenal insufficiency. Repeated biopsies from the mass revealed actinomycosis with no features of malignancy, while computed tomography scanning revealed a left maxillary sinus mass with invasive features and bilateral large adrenal masses. Blood and urine investigations showed adrenal insufficiency. The patient was treated as actinomycosis with adrenal involvement and was given intravenous penicillin and intravenous hydrocortisone. However, his condition did not improve and new signs appeared, that of left facial swelling and lymphadenopathy. A repeat biopsy of the palatal and adrenal masses revealed B-cell lymphoma. This case highlights the possibility that actinomycosis and lymphoma may share similar clinical presentations and may coexist. Either may mask and/or mimic the other, thus causing a delay in diagnosis. We describe the clinical progress and review the related literature. Interestingly, 9 out of the 12 reported cases of concomitant actinomycosis and malignancy (including this case) involve haematological malignancy. A high index of suspicion and treatment response reassessment is important in the management of either rare clinical entity.

The dangers of accepting a single diagnosis: case report of concurrent Plasmodium knowlesi malaria and dengue infection.

BACKGROUND: Dengue and malaria are two common, mosquito-borne infections, which may lead to mortality if not managed properly. Concurrent infections of dengue and malaria are rare due to the different habitats of its vectors and activities of different carrier mosquitoes. The first case reported was in 2005. Since then, several concurrent infections have been reported between the dengue virus (DENV) and the malaria protozoans, Plasmodium falciparum and Plasmodium vivax. Symptoms of each infection may be masked by a simultaneous second infection, resulting in late treatment and severe complications. Plasmodium knowlesi is also a common cause of malaria in Malaysia with one of the highest rates of mortality. This report is one of the earliest in literature of concomitant infection between DENV and P. knowlesi in which a delay in diagnosis had placed a patient in a life-threatening situation. CASE PRESENTATION: A 59-year old man staying near the Belum-Temengor rainforest at the Malaysia-Thailand border was admitted with fever for 6 days, with respiratory distress. His non-structural protein 1 antigen and Anti-DENV Immunoglobulin M tests were positive. He was treated for severe dengue with compensated shock. Treating the dengue had so distracted the clinicians that a blood film for the malaria parasite was not done. Despite aggressive supportive treatment in the intensive care unit (ICU), the patient had unresolved acidosis as well as multi-organ failure involving respiratory, renal, liver, and haematological systems. It was due to the presentation of shivering in the ICU, that a blood film was done on the second day that revealed the presence of P. knowlesi with a parasite count of 520,000/µL. The patient was subsequently treated with artesunate-doxycycline and made a good recovery after nine days in ICU. CONCLUSIONS: This case contributes to the body of literature on co-infection between DENV and P. knowlesi and highlights the clinical consequences, which can be severe. Awareness should be raised among health-care workers on the possibility of dengue-malaria co-infection in this region. Further research is required to determine the real incidence and risk of co-infection in order to improve the management of acute febrile illness.

Early Onset of Squamous Cell Carcinoma Arising From Tuberculosis Verrucosa Cutis.

A 72-year-old man presented with a chronic scaly verrucous plaque over his right knee for nine months. The lesion was preceded by a well healed scar sustained five years back from a road traffic accident. He was given multiple courses of systemic antibiotic and antifungal medications but to no avail. A skin biopsy confirmed cutaneous tuberculosis. The area of plaque subsided significantly with antituberculosis treatment. However, during the second month of treatment, a new onset of a red fleshy granulating growth developed on the pre-existing site. A repeat skin biopsy revealed squamous cell carcinoma (SCC). He was subsequently referred for surgical excision. This is presumably the first reported case of SCC arising from tuberculosis verrucosa cutis. While most malignant transformations from tuberculosis has been thought to develop after a long period of time (usually more than twenty-five years), this case report showed that it may also occur within a short period of time. Awareness on this condition is important because any delay in diagnosis and treatment may have detrimental consequences.

Difficult mask ventilation: simple step to make the impossible, possible!

Mask ventilation is one of the most important skills in airway management. Difficulty in mask ventilation can become life threatening if it is associated with difficulty in intubation during general anesthesia. We report a potential impossible ventilation condition which was safely and easily overcome with appropriate innovative modification of an Opsite adhesive film.
