Subcutaneous Sarcoidosis in a Nigerian female

Sarcoidosis is relatively uncommon in indigenous black Africans, especially along the West African coast. There has not been any report of isolated cutaneous sarcoidosis from our center. We present a patient who was reviewed with an isolated ganglion-like subcutaneous swelling on the ankle region. Excision biopsy revealed a non caseating granulomatous lesion. Systemic evaluation was not remarkable and the lesion was negative for tuberculosis and fungi. The operative wound healed with the use of of a combination therapy with oral chloroquine, prednisolone, and methotrexate. We conclude that cutenous sarcoidosis can occur in the absence of systemic disease and definitive diagnosis is by histological finding of a non caseating granuloma, when other potential causes such as tuberculosis are excluded

Cystographic evaluation post colocystoplasty in two Nigerian indigenous dogs

A study was conducted to evaluate “graft-take” in an experimentally reconstructed urinary bladder by colocystoplasty in two adult dogs. Predetermined 2x3 cm dimension of urinary bladder defect was created on the dorsum and the ventrum of the urinary bladder and was patched with harvested 3x6 cm colonic pedicle flap. All operations were humanely conducted. Urographic evaluation for graft-take was done on days 21 and 49 post colocystoplasty by infusing Urografin(R)-76% (sodium amidotrizoate + meglumine amidotrizoate + Iodine) transurethrally. The urinary bladder architecture was preserved and maintained without obvious evidence of the grafted portion. The cystogram revealed an apparent dome-shaped with slight irregular mural thickness at day 21 which was not displayed cystographically on day 49 postoperative. This was evident of the textural difference of the colonic flap compared with the thicker urinary bladder. The healing pattern and the return to physiologic function of the reconstructed urinary bladder conclusively revealed that the colonic pedicle flaps are useful in repair of major urinary bladder defect. These flaps are suitable graft tissues.Keywords: Urinary bladder, Colocystoplasty, Cystography, Nigerian Indigenous dog

Thyroid Cancers in Nodular Goiters in Kano, Nigeria

Cancer is an occasional incidental finding in nodular goiter, but there has been no formal study on this disease in our locality. To determine the occurrence of histologically diagnosed malignancy in patients who presentwith nodular goiters. This is a 7- year (2000-2006) retrospective study of all histologically diagnosed malignancies within nodular goiters atAminuKanoTeachingHospital,Kano There were 160 multinodular goiters during the study period, out of which 24 (15.0%) had histologically diagnosed cancer, and 1 out of the thirteen patients with solitary thyroid nodule (7.6%) had carcinoma. The ages of the patients with carcinoma ranged from 16 to 65 years, with amean age of 38.8 years. Eighteen (72%) were females, and 7(28%) were males. Six out of the 25 cases of carcinoma were detected preoperatively by fine needle aspiration cytology. Well differentiated follicular carcinoma was the predominant histological type in 13(52%) cases, followed by papillary in 10(40%), medullary carcinoma in 1(4%) and anaplastic carcinoma in 1(4%) patient. One-seventh of nodular goiters in our center harbouredmalignancy, and follicular carcinomawas the prevalent histological type. This is consistent with the findings elsewhere in endemic goitrous regions. Ultrasound guided fine needle aspirationwould improve preoperative diagnosis and guide appropriate surgical management.Keywords: thyroid, nodular goiters,malignancy, fine needle aspiration cytology

Production Micro and Nano magnesium powder by Pulsed Laser Ablation

In this work, magnesium oxide micro/nano particles were prepared using laser ablation in deionized water. This is technique very simple, cheap and a single step method. In the present work, at which ablation of pure Mg metal target in deionized water was accomplished using 9nsec Q-switched Nd:YAG laser at 1064 nm laser wavelength, the effect of laser energy on particle size material and the effect of number of laser pulses on optical properties and surface morphology have been studied. UV-visible measurement showed that a red shift in the absorption spectra of MgO NPs is obtained with increasing number of laser pulses. X-ray Florence's (XRF) investigation showed the Mg metal powder percentage purities. Particle size analysis (PZA) investigation showed the particle size distribution of magnesium in deionized water after laser ablation. Atomic force microscope (AFM) investigation showed that magnesium oxide nanoparticles have root mean square of surface roughness 0.954 nm and particle size distribution of magnesium was (15-155)nm after laser ablation

Design Study of Leak Detection System and the Protection of Crude Oil Pipelines

In this paper, the Oil leakage sensor utilized photonics crystal fiber interferometer (PCFI) is proposed and experimentally investigated. The principle of operation of this sensor is detected the gas emission from pipe. This sensor is operate in transmission mode which designed by splicing the LAM-10 PCF with single mode fiber (SM) with two side. To increase the sensitivity of this sensor the splice region is coated by special polymer doping by nano sliver silver particles to increase the sensitivity. The experimental result s shows the sensitivity of fabricated sensor is high, and the response time is very short reach to 2min the max sensitivity is equal to (62 Co./sec ). Due to the low fiber loss, the sensing range can be as high as 1 km

Dermatological Malignancies in Kano, Northern Nigeria: A Histopathological Review

Background: Globally, dermatological malignancies are among the most common form of cancer but there has been no formal study in our locality. Method: This is a five year (1998-2002) retrospective review of 125 histologically diagnosed skin malignancies to document the pattern of skin cancer in Kano, the largest city in Northern Nigeria. Results: Malignant skin tumours comprised 12.7% of all histologically diagnosed cancers. As in other Negroid populations, squamous cell carcinoma was the most common constituting 40%, followed by melanomas comprising 34%. Cutaneous malignancies were most prevalent in the 6th and 7th decades of life and males were slightly preponderant (M: F = 1.2:1). The lower limbs were the most frequent site accounting for 70% of all malignant cutaneous neoplasms. Conclusion: Our findings were similar to most studies from other parts of Africa but significantly at variance with Caucasian populations in the developed world. Proper wound care, protective footwear and human immunodeficiency virus (HIV) control can substantially reduce the incidence, morbidity and mortality of skin cancer in Kano

Future and potential spending on health 2015-40: Development assistance for health, and government, prepaid private, and out-of-pocket health spending in 184 countries

Background: The amount of resources, particularly prepaid resources, available for health can affect access to health care and health outcomes. Although health spending tends to increase with economic development, tremendous variation exists among health financing systems. Estimates of future spending can be beneficial for policy makers and planners, and can identify financing gaps. In this study, we estimate future gross domestic product (GDP), all-sector government spending, and health spending disaggregated by source, and we compare expected future spending to potential future spending. Methods: We extracted GDP, government spending in 184 countries from 1980-2015, and health spend data from 1995-2014. We used a series of ensemble models to estimate future GDP, all-sector government spending, development assistance for health, and government, out-of-pocket, and prepaid private health spending through 2040. We used frontier analyses to identify patterns exhibited by the countries that dedicate the most funding to health, and used these frontiers to estimate potential health spending for each low-income or middle-income country. All estimates are inflation and purchasing power adjusted. Findings: We estimated that global spending on health will increase from US$9.21 trillion in 2014 to$24.24 trillion (uncertainty interval [UI] 20.47-29.72) in 2040. We expect per capita health spending to increase fastest in upper-middle-income countries, at 5.3% (UI 4.1-6.8) per year. This growth is driven by continued growth in GDP, government spending, and government health spending. Lower-middle income countries are expected to grow at 4.2% (3.8-4.9). High-income countries are expected to grow at 2.1% (UI 1.8-2.4) and low-income countries are expected to grow at 1.8% (1.0-2.8). Despite this growth, health spending per capita in low-income countries is expected to remain low, at $154 (UI 133-181) per capita in 2030 and$195 (157-258) per capita in 2040. Increases in national health spending to reach the level of the countries who spend the most on health, relative to their level of economic development, would mean $321 (157-258) per capita was available for health in 2040 in low-income countries. Interpretation: Health spending is associated with economic development but past trends and relationships suggest that spending will remain variable, and low in some low-resource settings. Policy change could lead to increased health spending, although for the poorest countries external support might remain essential
