Waleed M. Hussen, Abdulsalam Y. Taha, Diar S. Hama-Kareem
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.63019
Background: Carotid body tumour (CBT) is a rare neoplasm, yet it is the commonest head and neck paraganglioma. In Iraq, relevant literature is sparse. Herein, we present our second case series. Methodology: Patients with CBTs that were operated upon in the Department of Thoracic and Vascular Surgery, Baghdad Medical City from 2010 to 2014 were enrolled. History and examination were followed by a workup of duplex ultrasonography, CT scan, magnetic resonance imaging, CT or conventional carotid angiography. Surgical exploration via a standard anterolateral cervical incision and subadventitial dissection was used to resect the tumours with preservation of carotid arteries. Intra-luminal carotid shunts and vein grafts were prepared to be used if necessary. Results: There were 5 males and 2 females aging 17 - 46 with a mean of 32.9 ± 9.8 year. All patients had slowly growing painless pulsatile swelling below mandiblular angle for long durations (1 - 25 years) and a positive Fontaine’s sign. All tumours were benign, unilateral (right n = 4, left n = 3) and ranging in size from 3 × 3 cm to 6.4 × 3.2 cm. Beside US neck exam, carotid angiography was done in 5 patients. According to Shamblin classification, 4 were class II, 2 class I and 1 class III. All tumours were successfully resected with preservation of ICA. However, the ECA was safely ligated twice due to severe involvement. Tongue deviation occurred once (14.3%) but no patient died and none had stroke or recurrence. Conclusions: Our results of surgery for CBT compare very well with the international standards.

Abstract: Background: Urinary incontinence (UI) is generally defined as the involuntary loss of urine from the bladder through the urethral meatus. Filling cystometry is the method by which the pressure/ volume relationship of the bladder is measured during bladder filling. Purpose: To determine the value of diagnostic cystoscopy in addition to Urodynamic study (UDS) in patients with primary urinary incontinence. Material and Methods: 200 patients with primary incontinence studied prospectively from January 2013 to June 2014. Their age ranges from (14 - 93 years), 86.5% were female, and 13.5% of them were male. In addition to physical, neurological examination and bio-chemical investigations, urine analysis and urine culture with Ultra-sound and Post void residual volume (PVRV), all patients underwent diagnosticflexible cystoscopy under local anesthesia, and urodynamic study. Result: 43.5% of patients age were between (34 - 53 years), (39%) between (54 - 73 years), (9%) between (14 - 33 years) and (8.5%) were between (74 - 93 years). Atonic bladder on UDS were (40.5%), Detrusor over activity (29%), patients with normal UDS were (22%) and patients that had DSD (Detrusor Sphincter Dyssynergia) were (8.5%). Eighty-four cases (42%) were found to have normal cystoscopy, those with grade-I-II bladder wall trabeculations were (49%) and patients with grade-III were (8.5%). Sixty-one patients (30.5%) with normal diagnostic cystoscopy have abnormal UDS (Atonic bladder, over-active bladder and DSD) while twenty-one (10.5%) patients with normal UDS had bladder wall trabeculations (grade-I-III) on diagnostic cystoscopy. Conclusion: Diagnostic cystoscopy in addition to urodynamic study will put in further knowledge in the assessment of patients with urinary incontinence. To some extent, it can predict the diagnosis.

From dependency to Interdependencies: The emergence of a socially rooted but commercial waste sector in Kampala City, Uganda
B Kareem, S Lwasa
African Journal of Environmental Science and Technology , 2011,
Abstract: Urban waste has traditionally remained for municipal councils to manage in several sub-Saharan cities such as Kampala. However, due to noticeable inefficiencies at municipal level, there is a manifest of low-income groups that take the initiative to extract and add value to materials from the waste stream, although higher-income groups are engaged in similar activities. This signifies the gradual shift from dependency on municipal councils to neighborhood interdependencies in the management of urban waste. To gain an in-depth understanding of this shift, we conducted purposive observations and twelve (12) focused-group interviews amongst selected respondents, in the neighborhood of Kasubi-Kawaala, Makerere II and Bwaise III parishes, located in the north western part of Kampala. The key finding was that waste-user roles, preferences, and the preceding generation and extraction processes are socially rooted in neighborhood cultural-orientations, and the underlying social mobility and commercial drivers. From the study, three (3) types of low-income commercial waste vendors were identified including, regular waste vendors, wholesale waste dealers, and home to home waste dealers. Unfortunately, these low-income waste vendors still have the least opportunity to negotiate with municipal authorities on scaling-up their commercial activities for a greater social impact.

Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.614124
Abstract: Corrosion control is an important aspect of safe drinking water supplies. The effects of corrosion which may not be evident without monitoring are an important issue concerning both public health and economical aspects. Chemical stability parameters of water quality in water treatment plants in Baghdad city can improve drinking water quality. The treated water quality from water treatment plants in Baghdad city was investigated along the water flow path in this study. The water quality parameters related to chemical stability included temperature, alkalinity as mg/L CaCO3, calcium mg/L as Ca, pH and total dissolved solids (TDS) mg/L for different samples from WTPs within Baghdad city were investigated. The two water quality indices, Langelier saturation index (LSI) and the Ryznar stability index (RSI), were calculated in order to evaluate the chemical stability of the drinking water samples. The results of LSI and RSI of the effluents from Baghdad’s WTPs during 2000-2013 classified that corrosive water is produced and this indicates that the water is not safe for domestic use and will need the further treatment. The present study demonstrated the application of water stability indices in estimating/understanding the treated water chemical stability and appeared to be promising in the field of treated water quality management.

Sarwar Noori Mahmood, Diar Hameed Bajalan
Open Journal of Urology (OJU) , 2016, DOI: 10.4236/oju.2016.63008
Abstract: Background: Among various intracorporeal lithotripters, pneumatic lithotripter has become the widely used tool for the treatment of urinary stones. Recently the holmium: YAG laser has been used with a wide range of potential urological applications, including intracorporeal lithotripsy of urinary calculi. Purpose: Compare the effectiveness and complications of treatment for ureteric stones between holmium laser lithotripsy and pneumatic lithotripsy. Material and Methods: Comparison of 100 patients presented with ureteric stones, group one (50) of whom were treated with pneumatic lithotripsy and group two (50) with holmium laser was done and the effectiveness and complications of both were analyzed. Results: There was no difference in patient age, sex, stone size and location of stones between the two groups. The immediate stone free rates were 88% in the holmium: YAG group and 66% in the pneumatic lithotripsy group (p < 0.05). The four weeks stone free rates were 98% and 94% respectively (p = 0.07). The mean ± SD operative time in the holmium: YAG group (40 ± 26 min) was shorter than those with pneumatic lithotripsy group (60 ± 40 min). Postoperative stay in hospital was less than 24 hours in holmium: YAG group (70.4%) and shorter than those for pneumatic group (29.6%) (p < 0.002). Post treatment complications such as ureteral perforation were encountered in only two patients who underwent pneumatic lithotripsy. Other complications, such as mucosal injury, ureteral perforation and postoperative fever; there was no statistically significant difference between the two groups. While light hematuria was found more frequently in the pneumatic group (14%) in comparison to laser group (12%) (p = 0.02). On the other hand, the overall complication rates between the two groups was statistically significant (8%) laser group vs. (32%) pneumatic group (p = 0.003). Conclusions: Holmium: YAG laser lithotripsy was associated with shorter operation time and postoperative hospitalization period. These data suggest that holmium: YAG lithotripsy was safe and more effective than Pneumatic lithotripsy in the aspect of immediate stone free rate. We believe that holmium: YAG is an excellent treatment modality for managing ureteral calculi.

Physics , 1996, DOI: 10.1103/PhysRevA.56.2233
Abstract: The two-photon correlation of the light pulse emitted from a sonoluminescence bubble is discussed. It is shown that several important information about the mechanism of light emission, such as the time-scale and the shape of the emission region could be obtained from the HBT interferometry. We also argue that such a measurement may serve to reject one of the two currently suggested emission mechanisms, i.e., thermal process versus dynamical Casimir effect.

Abiodun S. Bankole,Kareem Olayinka Idowu
Journal of Economics Theory , 2012, DOI: 10.3923/jeth.2010.79.83
Abstract: Africa s growth sustainability depends in part on the extent to which it can exploit opportunities that are bound in trade. Many of Africa s major exports are confronted with trade barriers in the markets of their trade partners. These barriers make it difficult for the continent to take advantage of the opportunity that abounds in trade. It is to this end that this study evaluates the effects of trade barriers in the European Union (EU) on African exports. The researchers found that tariffs are the major trade barriers to Africa s exports in the EU market, however the non-tariff barriers significantly affect Africa s exports to this market.
UV-Absorbing Pigments from Some Saudi-Arabian Algal Species
Mohamed S.M. Abdel-Kareem
International Journal of Botany , 2008,
Abstract: A total of 17 Saudi-Arabian algal species related to 4 classes (Cyanophyceae, Rhodophyceae, Phaeophyceae and Chlorophyceae) were screened for the presence of UV-absorbing pigments. Irradiation experiment was conducted on Cladophora glauescens to assess the response of this species to extradoses of UV-B radiation. All the investigated species contain UV-B absorbing pigments. Although it has been suggested that green algae commonly contain low levels of UV-absorbing pigments some investigated green species showed promising quantities of these pigments. The amount of UV-absorbing pigments of Cladophora glauescens varied greatly according to the time as well as the distance of irradiation. Chlorophyll a, Chlorophyll b and carotenoids contents of the investigated species were also assessed.
