Small-cell lung cancer (SCLC) is a lung cancer histological subtype unusual in its favorable response to cytotoxic chemotherapy. Life-threatening manifestations at presentation are rarely reported and should be an important clinical concern. We report a case of a 63-year-old man presenting with rapid-onset refractory severe thrombocytopenia, development of massive hemoptysis, and death from respiratory failure. This case provides clinicians a reference for this unusual presentation and carries clinical implications for managing SCLC patients.

INTRODUCTION: Despite increasing efforts to address the reproductive health needs of persons living with Human Immuno-Deficiency Virus (HIV), a high unmet need for contraception exists among HIV+ women in sub-Saharan Africa. Currently, Ethiopia promotes integration of family planning (FP) services in to HIV chronic care. Yet the contraceptive prevalence rate among clients remains low. The objective of the study was to assess the role of socio-cultural factors on modern family planning use among HIV+ clients attending Anti-Retroviral Therapy clinics in Addis Ababa sub-cities. METHODS: the study involved a facility based cross sectional survey. The ten sub cities were initially categorized/stratified into 5 based on direction (East, West, South, North and Central) and from each category one sub city was randomly selected. The total sample size was proportionally allocated to the selected health facilities according to previous monthly average client load per health center. Participants were selected using simple random sampling technique during their routine visit at the health centers. Data were collected through a semi-structured interviewer administered questionnaire. Both descriptive and inferential statistics were generated and results considered significant at 95% confidence level using STATA version 14.0. RESULTS: six hundred and thirty-six clients participated in the study. Majority of them were age between 30-39 years. Though majority, 607 (95.4%) participants approved the use of modern FP method, current use rate stood at 39%. Condom was the most (14.5%) commonly used single method. The odds of FP use by participants who disclosed their HIV status were almost twice that of their counterparts (AOR= 1.84; 95% CI: 1.14, 2.95). Participants who held discussion with their spouse/partners concerning FP, irrespective of the frequency had an odd of more than four when using FP than their counterparts (AO= 4.35; 95% CI: 2.69, 7.04). CONCLUSION: this study revealed that 6 out of every 10 HIV+ clients are not currently using FP methods. Disclosure of HIV status as well as open discussion with spouse/partner were positively associated with family planning use. These study findings call for comprehensive and client focus FP education and counseling in line with disclosure of HIV status and dialogue with spouse/partner in order to increase uptake and utilization of FP among clients. Partners have a great influence on the use and choice of FP methods, so their views are paramount.

INTRODUCTION: Hepatitis B infection is caused by the Hepatitis B virus (HBV). HBV is transmitted through sexual intercourse, by exchange of saliva during kissing and also to newborns of infected mothers. In the Global Burden of Diseases 2010, 786,000 deaths were attributed to HBV. Studies in Cameroon, reported the prevalence of HBV as high as 10.1% and 12% among blood donors in hospital blood banks. This study therefore, aims at determining the prevalence of HBsAg, knowledge and practices of pregnant women on HBV prevention and transmission in the Limbe health district (LHD) and Muyuka health district (MHD). METHODS: ANC registers were exploited from the Health Centers for a period of three years (2014-2016) inorder to determine the prevalence of HBV infection. 270 women attending ANC were selected by exhaustive sampling. Knowledge and practices of participants on HBV prevention and transmission was assessed using a structured questionnaire. RESULTS: the prevalence of HBV in the LHD and MHD were 5.7% and 7.5% respectively. Pregnant women in the LHD demonstrated good knowledge but adopted poor practices whereas in the MHD, pregnant women demonstrated poor knowledge and adopted poor practices regarding the mode of transmission and prevention of HBV infection. There was a significant association between the prevalence of HBsAg and marital status (p = 0.000) in the LHD and age (p = 0.022) in the MHD. CONCLUSION: this study indicated a high prevalence of HBV among pregnant women in the LHD and MHD, knowledge and practices were identified as potential risk factors.

INTRODUCTION: Cervical cancer is ranked the 7th most common cancer in the world. Cancer of the cervix is the second most commonly diagnosed cancer after breast cancer and the third leading cause of cancer deaths among females in less developed countries. Incidence rates are highest in countries with low income. Nearly 90% of cervical cancer deaths occur in developing parts of the world. The study researchers therefore, carried out a retrospective study to determine the proportion of cervical cancer among other types of cancer in the cancer registry of the Bamenda Regional Hospital. METHODS: the objective of this study was to determine the proportion of cervical cancer among other types of cancers in the cancer registry of the Bamenda Regional Hospital, North West Region of Cameroon from past records. We reviewed all records from the registry of patients who attended the Bamenda Regional Hospital to screen and/or be operated upon for cervical cancer and other types of cancer. Socio-demographic and clinical characteristics of cases were captured using a data collection sheet: age, type of cancer, stage of cancer, type of surgery carried out and date of surgery. Data were entered and analysed in Statistical Package for Social Sciences (SPSS) version 25 software. RESULTS: 59 cancer cases were received in the center between 2012 and 2017. Of these, 31 (52%) had cervical cancer. Most patients who screened positive for cancer of the cervix were of the 50-54 age groups. Most of these patients (47.5%), were received at late stages (stages 3 and 4). CONCLUSION: over half (52%) of the patients receiving cancer care in this center have cervical cancer and generally turn up late for management.

Caveolin-1 and caveolae are differentially polarized in migrating cells in various models, and caveolin-1 expression has been shown to quantitatively modulate cell migration. PTRF/cavin-1 is a cytoplasmic protein now established to be also necessary for caveola formation. Here we tested the effect of PTRF expression on cell migration. Using fluorescence imaging, quantitative proteomics, and cell migration assays we show that PTRF/cavin-1 modulates cellular polarization, and the subcellular localization of Rac1 and caveolin-1 in migrating cells as well as PKCα caveola recruitment. PTRF/cavin-1 quantitatively reduced cell migration, and induced mesenchymal epithelial reversion. Similar to caveolin-1, the polarization of PTRF/cavin-1 was dependent on the migration mode. By selectively manipulating PTRF/cavin-1 and caveolin-1 expression (and therefore caveola formation) in multiple cell systems, we unveil caveola-independent functions for both proteins in cell migration.

Abstract Introduction Pulmonary ossification has been rarely observed in pulmonary fibrosis and in some chronic respiratory diseases such as chronic obstructive pulmonary disease. We report here a metaplastic ossification in the bronchial cartilage of a patient with multi-drug resistant tuberculosis. Case presentation We report the case of a 41-year-old Asian man from Korea with chronic multi-drug resistant tuberculosis with a rare focus of bone formation from the cartilage of a bronchus subtending an active cavity. The patient had a large multi-lobed, thick-walled cavitary tuberculosis lesion in his left upper lobe. Severe infiltration of his lymphocytes and epithelioid cells, along with some giant cells and neutrophils, was observed in the patient's bronchial wall. Desquamated bronchial epithelium and acid-fast bacilli were found inside his bronchus. A small focus of bony metaplasia was found in the cartilage of his bronchial wall. Histopathological examination confirmed calcification and showed hematopoietic cells forming in his marrow cavity. Conclusions Chronic inflammation in the lungs of our patient, caused by underlying tuberculosis, probably played a role in the development of osseous metaplasia from the associated cartilage of the bronchial wall.
