PURPOSE: This study was performed to determine the prevalence of maxillary canine impaction on a basis of a single panoramic radiograph in Bangladeshi population. MATERIALS AND METHODS: A random sample of seven hundred panoramic radiographs was collected from the patient record of a dental clinic. All the selected panoramic radiographs were taken from January 2009 to August 2010 by a single panoramic radiograph machine with the same exposure time (19 seconds) for all radiographs. One hundred and twenty panoramic radiographs were excluded to minimize the selection bias. In a dim lit room, an observer assessed the radiographs on a standard radiographic light box. The position of the impacted maxillary canine was recorded in line with the longitudinal axis of a tooth using the edge of a metal ruler. Data were subsequently put on SPSS 11.5 software and chi-square (chi2) tests were applied to find out the association. RESULTS: Among 580 panoramic radiographs it was found that impacted maxillary canines were present in only 7 (1.2%) radiographs. A statistical significant difference was found between the age of the patients and the vertical position of the impacted canines (p=0.000) and between the age of the patients and the horizontal position of the impacted canines (p=0.003). CONCLUSION: The prevalence was found to be low compared with the present study from the limitation of panoramic image. Further study needs to include three-dimensional imaging modality.

Poultry farming not only provides high nutritious food but also creates employment
opportunity for rural masses. Documented evidences elaborates that helminth parasitism is
most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a
nematode of small intestine, has been considered as the most common and important parasite
of chicken. The present study was carried out to investigate prevalence and severity of A.
galli in White Leghorn layers (housing type: battery cage and deep litter, 50 each) and
Fayoumi-Rhode Island Red crossbred (male and female: 50 each) flock rearing at Government
Poultry Farm, Dina, Punjab, Pakistan. Two hundred faecal samples were examined by using
standard parasitological and McMaster egg counting technique. The overall prevalence was
24.5% at farm, 13% in White leghorn layer (battery cage=2%, deep litter=24%) and 36% in
Fayoumi-Rhode Island Red (male=34%, female=38%). It was also observed that White leghorn
layer rearing in deep litter had more severe infection (EPG=1920) of A. galli compare with
battery cages birds (EPG=500). Parasite prevalence was significantly related with sex (P<0.05)
in Fayoumi-Rhode Island Red and male birds had less number of average parasites (0.34±0.47)
as compared to females (0.38±0.490). Additionally, female birds were under serious threat of
infection (EPG=2270) compared with its counterpart (EPG=1250). Given the high infection
rates, particular attention should be paid to management and provision of feed supplement to
White leghorn layer housing in deep litter and female bird of Fayoumi-Rhode Island Red
crossbred.

Sulconazole has been reported to degrade into sulconazole sulfoxide via sulfur oxidation; however, structural characterization data was lacking and the potential formation of an N-oxide or sulfone could not be excluded. To clarify the degradation pathways and incorporate the impurity profile of sulconazole into the United States Pharmacopeia–National Formulary (USP–NF) monographs, a multifaceted approach was utilized to confirm the identity of the degradant. The approach combines stress testing of sulco-nazole nitrate, chemical synthesis of the degradant via a hydrogen peroxide-mediated oxidation reaction, semi-preparative HPLC purification, and structural elucidation by LC―MS/MS and NMR spectroscopy. Structural determination was primarily based on the comparison of spectroscopic data of sulconazole and the oxidative degradant. The mass spectrometric data have revealed a McLafferty-type rearrange-ment as the characteristic fragmentation pathway for alkyl sulfoxides with aβ-hydrogen atom, and was used to distinguish the sulfoxide from N-oxide or sulfone derivatives. Moreover, the generated sulco-nazole sulfoxide was utilized as reference material for compendial procedure development and valida-tion, which provides support for USP monograph modernization.

STUDY DESIGN: Cross sectional and observational. PURPOSE: To evaluate the different aspects of lumbar disc degenerative disc disease and relate them with magnetic resonance image (MRI) findings and symptoms. OVERVIEW OF LITERATURE: Lumbar disc degenerative disease has now been proven as the most common cause of low back pain throughout the world. It may present as disc herniation, lumbar spinal stenosis, facet joint arthropathy or any combination. Presenting symptoms of lumbar disc degeneration are lower back pain and sciatica which may be aggravated by standing, walking, bending, straining and coughing. METHODS: This study was conducted from January 2012 to June 2012. Study was conducted on the diagnosed patients of lumbar disc degeneration. Diagnostic criteria were based upon abnormal findings in MRI. Patients with prior back surgery, spine fractures, sacroiliac arthritis, metabolic bone disease, spinal infection, rheumatoid arthritis, active malignancy, and pregnancy were excluded. RESULTS: During the targeted months, 163 patients of lumbar disc degeneration with mean age of 43.92+/-11.76 years, came into Neurosurgery department. Disc degeneration was most commonly present at the level of L4/L5 105 (64.4%).Commonest types of disc degeneration were disc herniation 109 (66.9%) and lumbar spinal stenosis 37 (22.7%). Spondylolisthesis was commonly present at L5/S1 10 (6.1%) and associated mostly with lumbar spinal stenosis 7 (18.9%). CONCLUSIONS: Results reported the frequent occurrence of lumbar disc degenerative disease in advance age. Research efforts should endeavor to reduce risk factors and improve the quality of life.

Canine babesiosis is an important tick-borne protozoal disease of dogs that poses major health problem worldwide. Farm dogs in rural areas are the companion animals, that not only watch the livestock herds but also guard the house of the owners. Each farmer keeps his companion dog to get all the services. In our study, a total of 450 blood samples of farm dogs from three different ecological zones (Southern, Central and Northern regions of the province; Punjab) of Pakistan, were collected to examine through microscopy and PCR. Examination of thin blood smears revealed an overall prevalence of 12.8% (58/450) of canine babesisal parasites. However, PCR analysis revealed 46.8% (211/450) and 7.3% (33/450) samples positive for B. gibsoni and B. vogeli, respectively. The amplicons of 671 bp and 590 bp were amplified for the detection of B. gibsoni and B. vogeli, respectively through PCR. The results of multivariate analysis showed that the occurrence of canine babesiosis is higher in the Central Punjab and younger age of the dogs, while breed and sex of the host were not significantly associated with the occurrence of the disease. Mixed infection of B. gibsoni and B. vogeli was observed only in 3 dogs each in district Kasur and Rawalpindi. Our study is the first report to observe the occurrence of canine babesiosis in rural dogs in Pakistan through PCR.

Anaplasma marginale is the most prevalent tick-borne haemoparasite of cattle and causes huge
economic losses to the dairy industry worldwide. This study aimed to determine the occurrence of A.
marginale infection in blood and tick samples collected from livestock animals in the districts located
in Khyber Pakhtunkhwa (KPK), Pakistan. A total of 184 blood and 370 tick samples were included in this
study. It has never been reported that sheep, goats, and cattle in Tank, Ghulam Khan, Birmil and Miran
Shah areas were infected with A. marginale. All samples of blood and ticks were collected through
random sampling from March 2021 to January 2022 from cattle, sheep and goats and screened through
PCR for anaplasmosis by using primer pairs of Anaplasma spp. Three hundred and seventy ticks were
collected from infested hosts (120/184, 64.21%). Among the four morphologically identified tick species,
the highest occurrence was recorded for Rhipicephalus sanguineus (n=138, 37.29%), followed by
Rhipicephalus microplus (n=131, 35.4%), Rhipicephalus annulatus (n=40, 10.81%), Hyalomma anatolicum
(n=31, 8.37%), and Hyalomma marginatum (n=30, 8.1%). The occurrence of female tick was highest
(n=160, 43.24%), followed by nymphs (n=140, 37.38%) and males ticks (n=70, 18.9%). Among these ticks,
A. marginale was detected in female ticks of R. microplus, and R. sanguineus. Molecular identification
of A. marginale was confirmed in 120 out of 184 blood samples and 6 out of 74 tick samples. Overall,
occurrence of A. marginale in blood and tick samples was found to be 65.21% and 8.1% respectively.
Species-wise occurrence in blood samples of goats were 71.11% followed by sheep 68.31% and cattle
50%. Specie-wise occurrence of A. marginale in tick samples of cattle were 12.5% followed by goats
6.89%. The obtained sequence showed similarity with A. marginale reported from Kenya and USA. We
report the first PCR based detection of A. marginale infection in blood samples and in R. sanguineus
ticks of goats simultaneously.
