Successful recovery of MERS CoV pneumonia in a patient with acquired immunodeficiency syndrome: A case report

Middle East Respiratory Syndrome Coronavirus (MERS CoV) may cause severe pneumonia with significant morbidity and mortality, particularly in patients with multiple comorbid condition. MERS CoV pneumonia has not been previously reported in patients with Human Immunodeficiency Virus (HIV). Herein, we report a case of MERS CoV pneumonia with a successful outcome in a patient recently diagnosed with HIV.     

Common acute lymphoblastic leukaemia-lymphoma expressing cytokeratin: a case report

This report presents a case of common acute lymphoblastic leukaemia-lymphoma expressing low molecular weight cytokeratin but no leukocyte common antigen (CD45) in a 57-year-old man. The unusual morphology and clinical course together with the aberrant immunohistochemical results suggested a diagnosis of undifferentiated carcinoma. A detailed immunohistochemistry study on frozen and paraffin sections and molecular analysis prevented a diagnostic mistake.     

Multiple organ involvement in eosinophilic polymyositis: an autopsy report

This report describes autopsy findings of eosinophilic polymyositis in a 29-year-old woman. She complained of muscle pain and tenderness. A serum examination disclosed elevated creatine kinase, and echocardiography showed lowered cardiac function. Electromyography demonstrated myopathic potentials, and the skeletal muscle biopsy revealed degeneration of muscle fibers accompanying marked eosinophilic infiltration. Peripheral eosinophilia was not prominent. A systemic examination excluded possible etiologic factors, such as hypereosinophilic syndrome, collagen vascular diseases, or parasites. The patient died of heart failure after a 4-month clinical course. The autopsy disclosed a set of histological changes indicating tissue injuries, that is, loss of muscle fibers, interstitial fibrosis, and/or infiltrates of lymphocytes not only in the skeletal muscles and heart but also in various visceral organs. Eosinophils were sparsely scattered. These results indicate that the overrun of eosinophils underlying eosinophilic polymyositis, regardless of the presence of hypereosinophilic syndrome or other systemic disorders, could involve wide-ranging visceral organs.     

Community-acquired pneumonia in patients with bacterial meningitis: a prospective nationwide cohort study

ObjectivePneumonia is considered a focus of infection in patients presenting with community-acquired bacterial meningitis but the impact on disease course is unclear. The aim was to study presenting characteristics, clinical course and outcome of meningitis patients with co-existing pneumonia on admission.MethodsWe evaluated adult patients with community-acquired bacterial meningitis with pneumonia on admission in a nationwide, prospective cohort performed from March 2006 to June 2017. We performed logistic regression analysis to identify clinical characteristics predictive of pneumonia on admission, and to quantify the effect of pneumonia on outcome.ResultsPneumonia was diagnosed on admission in 315 of 1852 (17%) bacterial meningitis episodes and confirmed by chest X-ray in 256 of 308 (83%) episodes. Streptococcus pneumoniae was the causative organism in 256 of 315 episodes (81%). Pneumonia on admission was associated with advanced age (OR 1.03 per year increase, 95% CI 1.02–1.04, p < 0.001), alcoholism (OR 1.96, 95% CI 1.23–3.14, p 0.004), cancer (OR 1.54, 95% CI 1.12–2.13, p 0.008), absence of otitis or sinusitis (OR 0.44, 95% CI 0.32–0.59, p < 0.001) and S. pneumoniae (OR 2.14, 95% CI 1.55–2.95, p < 0.001) in the multivariate analysis. An unfavourable outcome defined as a score of 1–4 on the Glasgow Outcome Scale was observed in 172 (55%) episodes and 87 patients (28%) died. Pneumonia on admission was independently associated with unfavourable outcome and mortality in the multivariate analysis (OR 1.48, 95% CI 1.12–1.96; p 0.005).ConclusionPneumonia on admission in bacterial meningitis is a frequent coexisting infection and is independently associated with unfavourable outcome and mortality.

Clinical and pathological features of eosinophilic oesophagitis: a review

Eosinophilic oesophagitis (EOE) is a newly described clinicopathological entity that is being diagnosed with increasing frequency both in children and in adults. It is presumed to be an atopic disease involving both immediate and delayed-type hypersensitivity to inhaled and ingested allergens. Because of the reflux-type symptomatology, it is commonly misdiagnosed and treated as severe gastro-oesophageal reflux disease (GORD) before an appropriate diagnosis is made. Pathologically, EOE is an inflammatory disorder with a predominantly eosinophilic infiltrate that is unresponsive to acid suppression therapy. The diagnosis of this disease requires histological confirmation with oesophageal biopsy specimens showing an intense eosinophilic infiltration. Although precise criteria or a specific cutoff point for the diagnosis of eosinophilic oesophagitis have not been established, many authors suggest that one high-power field with >20 eosinophils or multiple high-power fields with >15 eosinophils, together with clinical and endoscopic findings, should be sufficient for diagnosis. Recognition of EOE and differentiation from GORD are important, since allergen elimination or anti-inflammatory therapy appears to be more effective than acid suppression in these patients. This review focuses on clinicopathological features and diagnosis of EOE in adults and children.     

Acute interstitial pneumonia in siblings: a case report

Acute interstitial pneumonia (AIP) is a rapidly progressive condition of unknown cause that occurs in a previously healthy individual and produces the histologic findings of diffuse alveolar damage. Since the term AIP was first introduced in 1986, there have been very few case reports of AIP in children. Here we present a case of AIP in a 3-yr-old girl whose other two siblings showed similar radiologic findings. The patient was confirmed to have AIP from autopsy showing histological findings of diffuse alveolar damage and proliferation of fibroblasts. Her 3-yr-old brother was also clinically and radiologically highly suspected as having AIP, and the other asymptomatic 8-yr-old sister was radiologically suspected as having AIP.     

Legionella pneumonia and HIV infection: a case report

Legionella pneumonia is commonly diagnosed in patients who are chronically immunosuppressed, but it is rarely diagnosed in patients who have HIV/AIDS. We report the successful diagnosis and treatment of Legionella pneumonia in a patient with HIV infection that was diagnosed at the same admission.     

Rhodococcus equi pneumonia in AIDS: a case report

We describe the first case, in Campania, of Rhodococcus equi pneumonia in an HIV positive subject. The clinical symptoms resolved after antibiotic therapy. The pulmonary lesion at 10 months of radiological follow up results just partially reduced in its diameters.     

Acute eosinophilic pneumonia associated with intramuscular administration of progesterone as luteal phase support after IVF: case report

We report two cases of acute eosinophilic pneumonia induced by i.m. administration of progesterone used as luteal phase support after IVF. For both patients, the symptoms began 3 weeks after the first injection of progesterone. Both patients were in respiratory distress, and one of them required ventilatory assistance for a week, with 5 days in the intensive care unit. Symptoms improved as the i.m. form was shifted to a vaginal form of progesterone together with the administration of corticosteroids. Sesame oil (used as excipient) and benzyl alcohol (used as preservative) could both be incriminated in the development of the hypersensitivity reaction. The need for luteal phase support is clearly established in IVF cycles with GnRH agonist protocols, and progesterone is the generally recommended compound. However, there is no definitive consensus regarding the optimal route of administration of progesterone. These two cases of acute drug-induced disease show that the use of i.m. progesterone can be associated with a severe morbidity in otherwise healthy young patients. This is an additional argument to advocate the use of vaginal progesterone as luteal support in IVF.     

Meningeal relapse in a patient with acute promyelocytic leukemia: a case report and review of the literature

The involvement of central nervous system is rare in acute promyelocytic leukemia (APL). We report a APL patient of a 41 yr-old Korean male who presented with fever and petechia. Complete molecular remission was achieved with all-trans retinoic acid (ATRA), idarubicin, and cytarabine. Ten months later, he complained of a mild headache. The results of the physical examination and the complete blood counts were normal. The examination of cerebrospinal fluid showed the presence of promyelocyte. Bone marrow studies showed cytogenetic remission but with molecular relapse. He was treated with intrathecal and systemic chemotherapy.     

Prevalence and associated factors of pneumonia among under-fives with acute respiratory symptoms: a cross sectional study at a Teaching Hospital in Bushenyi District,Western Uganda

ObjectivesThis study assessed the prevalence and associated factors of pneumonia among children under-five years presenting with acute respiratory symptoms.MethodologyThis was a cross sectional study at the Pediatric Department of Kampala International University – Teaching Hospital, from the month of April to August 2019. The study included 336 children aged 2 to 59 months presenting with acute respiratory symptoms to the pediatric clinic. Pneumonia diagnosis was made according to the World Health Organization definition, modified by a chest radiograph. Structured questionnaires were used to collect data on socio-demographic, environmental and nutrition factors and multivariate logistic regression analysis using STATA version 13.0 was done to assess for the factors independently associated with pneumonia.ResultsOf the 336 children with acute respiratory symptoms, eighty-six, 86 (25.6%) had pneumonia. Factors significantly associated with pneumonia included: age below 6 months (OR=3.2, 95%CI=1.17–8.51, p=0.023), rural residence (OR=5.7, 95%CI=2.97–11.05, p <0.001), not up-to-date for age immunization status (OR=2.9, 95%CI=1.05–7.98, p=0.039), severe acute malnutrition (OR=10.8, 95%CI=2.01–58.41, p=0.006), lack of exclusive breastfeeding during the first six months (OR=2.9, 95%CI=1.53–5.53, p=0.001) and exposure to cigarette smoke (OR=3.0, 95%CI=1.35–6.80, p=0.007).ConclusionThe prevalence of pneumonia in children under-five years was high. Most of the factors associated with pneumonia are modifiable; addressing these factors could reduce this prevalence.     

Successful treatment of recurrent hepatic Candida infection with fluconazole after chemotherapy for acute leukemia: a case report

Summary Hepatic candidiasis represents an increasingly difficult problem in immunocompromised patients. It has been recognized as a variant of disseminated candidiasis after a period of neutropenia. Establishment of diagnosis is difficult since liver biopsy as well as culture may be negative, in spite of the presence of fungus. Hepatic lesions are generally not detectable by ultrasound examination or computed tomography until the neutrophil count has returned to normal. The aim of this case report is to describe the problems related to the diagnosis and treatment of hepatic candidiasis following chemotherapy for acute leukemia. The report also provides further evidence that fluconazole, a new broad-spectrum antifungal drug, can be safely and effectively used for the long-term treatment of deep-seated hepatic candidiasis.

Chromophobe renal cell carcinoma,eosinophilic variant with papillary growth: a case report

We report the case of an 80-year-old man who presented with pathologically diagnosed chromophobe renal cell carcinoma composed of eosinophilic cells with partial papillary growth. The patient had a 2.5 cm diameter renal mass incidentally detected by abdominal ultrasound examination. Laparoscopic left partial nephrectomy was performed under a diagnosis of left renal tumor. Histopathology demonstrated uniform eosinophilic cuboidal cells growing with a partially papillary pattern: differential diagnosis of oncocytoma, papillary renal cell carcinoma, or oncocytic papillary renal cell carcinoma was necessary. Immunohistochemical staining with anti-monoclonal antibody 31 and -CD82 antibody, and choroid iron staining, were positive. Cytogenetic analysis by comparative genomic hybridization showed gains of chromosomes 1p, 9q, 19q, 20, and 21q, and losses of chromosomes 1p and q, 2q, 6q and 7q, leading to diagnosis of chromophobe RCC. We describe differential diagnosis for chromophobe renal cell carcinoma, eosinophilic variant, growing in a papillary fashion in the kidney.     

Cigarette smoking and age of menopause: a large prospective study

Objectives

One of the possible consequences of tobacco consumption is that it contributes to an earlier age of menopause, though the causal relationship is yet to be confirmed. This study aimed to examine the prospective association between smoking and earlier age of menopause in a cohort of middle age Australian women after adjustment for a number of potential confounders.

Study design

21-Year follow-up of a cohort prospective study, Brisbane, Australia.

Main outcome measures

Age of menopause measured at the 21-year follow-up. Smoking and menopausal status were assessed by self-report. Other covariates were measured prospectively in the previous follow-ups.

Results

This study is based on 3545 women who provided data on their menopausal status at the 21-year follow-up of the study, and prospective as well as concurrent data on smoking. In univariate analysis tobacco smoking during the reproductive life course, socio-economic status and gravidity were significantly associated with earlier age of menopause. In multivariate analyses women who smoked cigarettes were more likely to experience earlier menopause than non-smokers. Compared to current smokers, risk of early menopause was significantly lower in those women who quit smoking in the past.

Conclusions

The data suggest that the impact of smoking is independent of other covariates associated with both smoking and age of menopause. The findings raise the possibility that effective quit smoking interventions may lead to a later age of menopause, and reduce the risk of adverse health consequences of early menopause.     

Endogenous lipoid pneumonia presenting as solitary pulmonary nodule: a case report

A 63-year-old woman complained of hemoptysis was admitted to our hospital. Chest computed tomography (CT) showed a solitary pulmonary nodule (SPN) arising from the lower lobe of the right lung which was considered as lung malignancy. The patient underwent video-assisted thoracoscopic surgery (VATS) of pulmonary wedge resection to remove the nodule. Diagnosis of lipoid pneumonia was established by multiple lipid-laden macrophages found in surgical specimen. As there was no history of inhalation or aspiration of lipid containing substances, she was diagnosed as endogenous lipoid pneumonia. The patient discharged from our hospital after surgery and with no recurrence in 9 months period.
