PURPOSE
To determine the likelihood of and risk factors for tear progression among patients with a symptomatic partial or full-thickness rotator cuff tears (RCTs) who return with continued shoulder pain and obtain subsequent magnetic resonance imaging (MRI) and to identify various patient factors and MRI findings associated with rotator cuff tear progression.
METHODS
We performed a retrospective review of MRI studies from Veteran's Affair patients with conservatively treated partial- or full-thickness rotator cuff tears. Patient characteristics and demographics were obtained via chart review. Tear characteristics were measured on MRI obtained a minimum of 1 year apart. We defined progression as either (1) an increase from a partial to a full-thickness tear or (2) an increase in tear width or retraction of at least 5 mm. Statistical analysis using χ, Fisher exact, Student , and Mann-Whitney test was then performed as appropriate, looking for factors involved in RCT progression.
RESULTS
We evaluated 412 MRI studies from 206 Veteran's Affair patients with conservatively treated partial- or full-thickness rotator cuff tears from October 1999 to March 2020. Overall, 61% of RCTs had progressed at a mean of 3.2 ± 2.3 years follow-up. Among all patients, 74% of full-thickness tears progressed in size, 42% of partial-thickness tears progressed in size, and 29% of partial-thickness tears progressed to full-thickness tears. On univariate analysis, full-thickness tears ( < .001), disruption of the anterior rotator cuff cable ( = .001), subscapularis involvement ( = .004), tear retraction ( < .001), and tear width ( < .001) all increased the likelihood of progression. On multivariate analysis, full-thickness tears ( < .001) and subscapularis involvement ( = .045) were correlated with progression.
CONCLUSIONS
RCTs progress over time in terms of size of tear and from partial- to full-thickness tears. There is an increased risk of tear progression in patients with full-thickness tears when compared with partial-thickness tears along with subscapularis tear involvement. Rates of progression are larger than previously reported rates for both partial- and full-thickness tears, noting that our study population were those patients who continued to be symptomatic from their tears.

Twelve cases with circling seizures are presented with their clinical, electroencephalographic and radiological findings. Four patients had symptomatic partial epilepsy, five had cryptogenic partial epilepsy, and the remaining three had idiopathic generalized epilepsy. Three of the patients with symptomatic partial epilepsy had frontal lesion, and one had parito-occipital lesion. Turning direction had no lateralizing value in patients with partial epilepsy. Based on our study we conclude that circling seizures may occur in different epileptic syndromes and epilepsies. In cases with symptomatic partial epilepsy, lesions are mostly located in frontal lobes but also in parietooccipital areas.

Review
AIM
To describe the association between partial thrombosis of the corpus cavernosum, partial priapism, and hard flaccid syndrome.
METHODS
A scoping review was performed according to the recommendations of the Joanna Briggs Institute. Moreover, we performed a search strategy using the MEDLINE, EMBASE, and CENTRAL databases. We included the available information, evaluating the conditions of partial thrombosis of the corpus cavernosum, partial priapism, and hard flaccid syndrome, and their molecular and physiological mechanisms and clinical presentation.
RESULTS
We identified 207 articles and chose eight studies published between 2001 and 2021. The total number of patients was 34, and their mean age was 28.2 years. Moreover, in 84% of the studies, the pathophysiology of the events was related to microtrauma or prolonged perineal compression. Additionally, 94.2% of the patients had some degree of erectile dysfunction. In addition, out of all patients, 94% underwent magnetic resonance imaging (MRI). However, patients with hard flaccid syndrome did not show relevant findings in these studies. Conversely, MRI showed asymmetry in the proximal corpora cavernosa, thrombosed corpus cavernosum segments, and mainly cavernous fibrous septum in patients with partial cavernous thrombosis and partial priapism.
CONCLUSION
Partial thrombosis of the corpus cavernosum, partial priapism, and hard flaccid syndrome occurred more frequently in young patients, possibly related to microtraumas that generate cavernous fibrosis and trigger alterations in the erection of the distal portion of the penis. Additionally, they cause proximal hardening of the pelvis, perineal pain, painful ejaculations, and cavernous asymmetry. Moreover, the imaging characteristics are similar in patients with partial priapism and partial cavernous thrombosis.

The evolution of cooperation in microbes is a challenge to explain because microbes producing costly goods for the benefit of any strain types (cooperators) often withstand the threat of elimination by interacting with individuals that exploit these benefits without contributing (defectors). Here we developed an individual-based model to investigate whether partial privatization via the partial secretion of goods can favor cooperation in structured, surface-attaching microbial populations, biofilms. Whether partial secretion can favor cooperation in biofilms is unclear for two reasons. First, while partial privatization has been shown to foster cooperation in unstructured populations, little is known about the role of partial privatization in biofilms. Second, while limited diffusion of goods favors cooperation in biofilms because molecules are more likely to be shared with genetically-related individuals, partial secretion reduces goods that could have been directed towards genetically related individuals. Our results show that although partial secretion weakens the role that limited diffusion has on fostering cooperation, partial secretion favors cooperation in biofilms. Overall, our results provide predictions that future experiments could test to reveal contributions of relatedness and partial secretion to the social evolution of biofilms.

Review
Partial edentulism, one or more teeth missing is an indication of healthy behaviour of dental practices in the society and attitude towards dental and oral care. The pattern of partial edentulism has been evaluated in many selected populations in different countries by different methods. Most of the studies have evaluated partial edentulism by surveying of Removable Partial Dentures (RPDs), patients visiting clinics, clinical records and population in particular locality. The objective of the study is to review the prevalence of partial edentulousness and its correlation to age,gender, arch predominance, socio economic factors and incidence of various Kennedy's Classes. Key observations drawn from the review are as below. There is no gender correlation for partial edentulism.Prevalence of partial edentulism is more common in mandibular arch than maxillary arch.Younger adults have more Class III and IV RPDs. Elders have more distal extension RPDs Class I and II.

The -value calculation methods for the partial and semi-partial correaltion coefficients were proposed by Cohen (2003) and Kim (2015). The method of Cohen (2003) depends on a single and identical statistic for both partial and semi-partial correlations, while Kim (2015)'s method uses two separate statistics for each of partial and semi-partial correlations. In particular, the mathematical expression of the -value calculation for the semi-partial correlation coefficient differs between Kim (2015) and Cohen (2003). Thus, these two expressions were compared through theoretical aspects and simulations. The results show that the semi-partial correlation coefficients by Kim (2015) is monotonic to the corresponding p-values, while Cohen (2003)'s method does not maintain monotonicity.

Edentulism and dental disease have a major effect on the standard of lifetime of patients. Fixed partial dentures have become the treatment of choice for many people for the replacement of edentulous space in the oral cavity. Therefore, it is of interest to correlate and compare the esthetics between monolithic zirconia and hand layered zirconia among fixed partial dentures in Saveetha Dental College. 100 patients who monolithic zirconia and hand layered zirconia had fixed partial dentures were included within the study. Pink and white esthetic scores were evaluated. Data collected were entered in SPSS and analyzed through Chi square test. It was observed that hand layered zirconia have better white esthetic score (p<0.000) and pink esthetic score (p<0.003) when compared to monolithic zirconia fixed partial dentures, which were statistically significant. It was concluded that hand layered zirconia fixed partial dentures have better esthetics than monolithic zirconia fixed partial dentures.

Review
The standard of care treatment for solitary renal cell carcinoma (RCC) tumors 4 cm or less is partial nephrectomy (PNx). However, multifocal kidney cancer presents unique challenges for treating physicians. Historically, total nephrectomy and hemodialysis with possible renal transplant later was the primary therapeutic strategy for these patients. Later, as nephron sparing surgical approaches improved, PNx became the standard of care for patients presenting with multifocal and hereditary RCC. Surgeries to remove multiple renal tumors simultaneously produce different perioperative outcomes and increased risk of complications. Due to these differences in technique and outcomes, the term multiplex partial nephrectomy (MxPNx) has been coined to designate these differences. Here, we discuss the role that MxPNx continues to play in multifocal RCC.
