A 17-year-old girl presented with secondary amenorrhoea. She developed normal age-appropriate secondary sexual characteristics and attained menarche at the age of 13 years. One year following her menarche, she was diagnosed with acute myeloid leukaemia and was treated with chemotherapy, total body radiation and bone marrow transplant with complete remission. The matched donor was her elder male sibling. Her evaluation for secondary amenorrhoea included full hormonal analysis and pelvic ultrasound scan. These suggested hypergonadotrophic hypogonadism with a normal uterus and ovaries. Peripheral leucocyte karyotype as part of routine hypogonadism workup was found to be 46 XY. The differential diagnosis of Swyer syndrome, which entails surgical removal of gonads due to the high risk of gonadoblastoma, was raised initially before reviewing the laboratory results of previous chromosomal analysis. Considering her medical history, the amenorrhoea was finally attributed to ovarian insufficiency due to chemotherapy and radiotherapy. The 46 XY karyotyping could be explained by the bone marrow transplant received from her donor brother. Hypogonadism causing amenorrhoea is commonly encountered after chemoradiotherapy. Pretreatment and post-treatment chromosomal analysis is essential in such cases. Karyotyping could be misleading especially if the patient suffered from graft-versus-host reaction post gender mismatched bone marrow transplant.The patient is a 64-year-old Caucasian woman with idiopathic chronic urticaria who presented to her primary care physician's office with mucoid otitis media. Medical history was significant for hypertension, hyperlipidaemia, allergic rhinitis, pre-diabetes, gastro-oesophageal reflux, paroxysmal atrial fibrillation, chronic kidney disease, diverticulosis with prior diverticulitis and history of recurrent infections. check details Her chronic urticaria was initially treated with antibiotics, antihistamines and oral steroids, but later she developed refractory urticaria requiring dapsone with modest improvement. When she presented with mucoid otitis media, immunoglobulin levels were found to be decreased. The pneumococcal vaccine antibody challenge confirmed the diagnosis of common variable immunodeficiency (CVID). Her HIV test was negative. She was started on intravenous immunoglobulin infusions and her chronic urticaria stabilised.In patients with chronic urticaria refractory to treatment, especially with a history of recurrent infections, a diagnosis of CVID should be considered, regardless of HIV status.Patients with symptomatic complex malignant pleural effusion (MPE) are frequently unfit for decortication and have a poorer prognosis. Septations can develop in MPE, which may lead to failure of complete drainage and pleural infection. Intrapleural fibrinolytic therapy (IPFT) is an alternative treatment. The use of IPFT in patients with anaemia and high risk for intrapleural bleeding is not well established. We report a successful drainage of complex haemoserous MPE with a single modified low-dose of intrapleural 5 mg of alteplase and 5 mg of dornase alfa in a patient with pre-existing anaemia with no significant risk of intrapleural bleeding.Doxycycline is a commonly prescribed antibiotic with growing evidence suggesting a possible linkage with drug-induced acute pancreatitis. We present an elderly female presenting with severe acute pancreatitis likely secondary to doxycycline therapy after thorough investigation. We reviewed the evidence linking doxycycline-inducing acute pancreatitis and signs and symptoms for severe disease. Early recognition and intervention are critical for positive patient outcomes.Iatrogenic iron overload, which is not uncommon in patients undergoing long-term haemodialysis, arises from a combination of multiple red cell transfusions and parenteral iron infusions that are administered to maintain a haemoglobin concentration of approximately 10 g/dL. Although iron overload due to genetic haemochromatosis is conventionally managed by phlebotomy, patients with haemoglobinopathies and chronic transfusion-induced iron overload are treated with iron-chelation therapy. However, the management of iron overload in our patient who presented with hepatic dysfunction and immunosuppressive drug-induced mild anaemia in the post-renal transplant setting posed unique challenges. We report on the decision-making process used in such a case that led to a successful clinical resolution of hepatic iron overload through the combined use of phlebotomy and erythropoiesis stimulating agents, while avoiding use of iron-chelating agents that could potentially compromise both hepatic and renal function.A 34-year-old woman presented with an unrelenting headache which had been ongoing since discharge from hospital 4 days before. She initially presented 2 weeks earlier with a 7 days history of severe headache, for which she had a CT scan, lumbar puncture and treatment for possible viral meningitis. The headache got worse 4 days after the lumbar puncture. Despite analgesics and bed rest, the headache persisted. A subsequent magnetic imaging scan demonstrated bilateral subdural effusions. She was given supportive treatment, which included advice concerning strict bed rest and analgesia. The headache took several months to abate. A third of patients suffer from post lumbar puncture headaches and this should be explained during informed consenting and post procedure. Not all post lumbar puncture headaches are simple headaches. A post lumbar puncture headache continuing for more than 7-14 days after the procedure requires further investigation to exclude life-threatening intracranial complications.
Accurate and reliable diagnosis is essential for lung cancer treatment. The study aim was to investigate interpathologist diagnostic concordance for pulmonary tumours according to WHO diagnostic criteria.

Fifty-two unselected lung and bronchial biopsies were diagnosed by a thoracic pathologist based on a broad spectrum of immunohistochemical (IHC) stainings, molecular data and clinical/radiological information. Slides stained with H&E, thyroid transcription factor-1 (TTF-1) clone SPT24 and p40 were scanned and provided digitally to 20 pathologists unaware of reference diagnoses. The pathologists independently diagnosed the cases and stated if further diagnostic markers were deemed necessary.

In 31 (60%) of the cases, ≥80% of the pathologists agreed with each other and with the reference diagnosis. Lower agreement was seen in non-small cell neuroendocrine tumours and in squamous cell carcinoma with diffuse TTF-1 positivity. Agreement with the reference diagnosis ranged from 26 to 45 (50%-87%) for the individual pathologists.
