Mugil Incilis

The mullet Mugil incilis is one of the most important fish resources in the Ciénaga Grande de Santa Marta. Based on monitoring of fishery statistics collected in the periods 1994-1996 and 2000-2007 and biological aspects of the species between 2006 and 2007, we evaluated fishing effects on the reproductive biology of M. incilis. Fishery statistics revealed that catch and fish size declined with time. Peak spawning was observed to occur between November - December, when the gonadosomatic index and condition factor showed their maximum values, contrasting with water salinity that plunged in the rainy period. Male: female ratio was estimated as 1:3 after a sample of 1954 individuals, and mean maturity size (MMS) calculated as 23.8 cm total length (TL), lower than that previously reported. Mullet represented 30 % of the whole fish catch in the period 1994-2007, and 65 % of the individuals were found below their MMS, mainly caught with cast-nets at spawning time. Lower occurrence of larger fish in the catch seems to be a reasonable explanation for the reduction of MMS. No evidence was found to attribute this decrease to a species strategy. Management measures for this fishery are discussed and suggested.

Reproduction and growth of the spiny lebbeid shrimp, Lebbeus groenlandicus (Fabricius, 1775), were investigated based on samples in the East Sea of Korea [= Sea of Japan], from January 2012 to April 2013. We collected 2964 shrimp samples during the study period, which included significantly more females than males (male : female ratio, 1.0 : 1.17). The females were generally larger than the males, and significant differences in the linear-regression slopes of carapace length (CL) versus body weight between the sexes indicate sex-specific differences in allometric growth. The gonadosomatic index (GSI) varied monthly, reaching a maximum in November 2012 (10.28) and a minimum in March 2013 (2.15). The proportion of ovigerous females varied from month to month. The highest values of the GSI coincided with the breeding period, and there was a significant difference between the mean GSI of females with non-eyed and those with eyed eggs, indicating that L. groenlandicus is a consecutive breeder. There was a significant correlation between CL and the number of eggs (EN) in the early egg stages. There was also a significant difference in the slopes of the regressions of CL versus EN between females carrying non-eyed and eyed egg stages. Based on the dry weights in the early egg stages, reproductive output was determined to be 0.18 ± 0.006. The Von Bertalanffy growth function parameters were CL∞ = 38.80 mm, year−1, , and WP = 0.4 for males, and CL∞ = 43.64 mm, year−1, , and WP = 0.6 for females. The growth performance index () was 2.86 for males and 2.89 for females.

Dynamic Population

In terms of fish dynamic population, reproduction is a process related with corporal size of each population member, which is tied with the spawning time and number of eggs produced. In order to relate the size of female little tuny (Euthynnus alletteratus), located in the southwest Gulf of Mexico, and its contribution in reproductive process, cycle and reproductive characteristics were analyzed by different size groups. Biological data were obtained by the artisanal fishing fleet of Antón Lizardo Veracruz community (Mexico). A total of 480 fish were caught from December 2009 to November 2012. Size structure, gonadosomatic index and duration and intensity spawning index were determined. The gonadosomatic index showed a decrease in the population after April and July. Nevertheless, this months and the fraction of spawning female may vary depending on size groups. According with the IDI, the individuals with the highest contribution in reproductive process belong to sizes from 44 to 56 cm. Therefore, in order to guarantee the conservation of this species, it is imperative to mainly direct the management measures towards the females from these sizes.

The author examined completed suicides occurring over a period of 25 years in a county of Hungary with a traditionally low (relatively speaking) suicide rate of 25.8. The rates are clearly higher in villages than in the towns. The male/female ratio was close to 4:1, among elderly though only 1.5:1. The high risk groups are the elderly, divorced, and widowed. Violent methods are chosen in 66.4% of the cases. The rates are particularly high in the period April-July. Prior communication of suicidal intention was revealed in 16.3% of all cases. Previous attempts had been undertaken by 17%, which in turn means that 83% of suicides were first attempts. In our material 10% the victims left suicide notes. Psychiatric disorders were present in 60.1% of the cases, and severe, multiple somatic illnesses (including malignomas) were present in 8.8%. The majority of the data resemble those found in the literature.

Abstract Background Road traffic accident (RTA) is the eighth leading cause of death worldwide. Motorcycle-associated head injury is the leading cause of road traffic associated morbidity and mortality in developing countries. Even though the incidence and mortality of head injury from motor cycle crash is on the increase in developing countries, especially in the African continent, most of the studies published in the literature on this subject matter took place in the developed Western countries. Methods This is a retrospective cross-sectional study of data from patients managed in our institution between December 2014 and November 2016. Results One hundred and eighty-four patients were analyzed. None of the patients used safety helmet for protection. The mean age was 27.6 ± 17.2 years with male female ratio of 6.7:1. Lone crash by cyclists and collisions accounted for 66.8% and 33.1% of the cases, respectively. Passengers and riders comprised 75% of the patients, while 25% were vulnerable pedestrians. The most frequently abused substance by the patients was tramadol (65.52%). Severe head injury and pupillary abnormality were found in 23.9% and 45.5% of the patients, respectively. Cranial CT scan showed abnormalities in 40.2% of the patients. Surgery was done in 28.3% of the patients with mortality rate of 20.7%. Conclusions The use of motorcycle as a mean of transportation has caused significant negative impact on the society. Young people, who constitute the workforce, are majorly affected, and this invariably leads to a serious economic burden on the concerned families and communities.

Background:During the last decade, the treatment of chronic inflammatory rheumatism (CIR) has been greatly improved with the advent of biotherapy.However, the use of biological treatment can lead to a number of side effects including abnormalities in the blood count.Objectives:The aim of this study was to assess the different hematological side effects of biological treatment in patients with rheumatoid arthritis (RA) and spondyloarthitis (SA).Methods:This study included patients with RA (ACR/EULAR 2010) and SA (ASAS 2009) registred with the Tunisian Biologic National Registry (BINAR).Patients were followed and treated with biologics for 2 years of less. Clinical data relative to biological treatment, including haematological side effects, have been collected.Results:Two hundred and ninety-eight patients (178 women and 111 men) were included in the study.The mean age was 49.2 ± 14.1 years. The male/female ratio was 0.6. The mean diseases durations for RA and SA were respectively 6.7 ± 3.5 years and 6.5 ±3.6 years.Anti-TNFα agents were prescribed in 87.9% of patients (n = 263) with respectively: Infliximab (20.4%) Etanercept (23.1%), Adalimumab (24.6%) and Certolizumab (26.5%).Tocilizumab and Rituximab were prescribed in 10.4% and 5% of the patients, respectively.Blood count abnormalities were noted in 15.4 % of patients (n=46).Neutropenia was the most frequently anomaly met on the hemogram (9.1%) followed by anemia (3.4%) and thrombocytopenia (3%). Pancytopenia was found in 11.4% of patients (n=34).The median time between biological therapy initiation and the onset of hematologic manifestations was 4.8 months [1-12]. Biological treatment was interrupted in two patients.In the other cases, the biological treatment was maintained with close monitoring of blood cell count. No case of death related to these hematological disturbances has been reported.Conclusion:In our registry, hematological side effects of biological treatment were found in 15.4% of cases and were noted with a median delay of 4.8 [1-12] months after the treatment initiation. Further studies are needed to confirm our preliminary results.Disclosure of Interests:None declared

Background: Pilomatricoma is a slow-growing, asymptomatic tumour originating from outer sheath cells of hair follicle. In this study, we describe the clinical presentation and histopathological features of pilomatricoma. Materials and Methods: This was a hospital based retrospective study carried out in all patients who were diagnosed as pilomatricoma over a period of January 2001 to December 2013. The study was done in department of pathology, Manipal Teaching Hospital, Nepal. Results: A total of 21 cases of pilomatricoma were reported with age range of 9-53 years (mean age 23.7) and male female ratio of 1:1.1. The most common site of occurrence was neck and preauricular region. The size of the tumour ranged from 0.3 to 4.7cm with a mean of 1.2cm. Multiple occurrences were seen in 3 patients and ossifying pilomarticoma was seen in 4 cases. Conclusion: Pilomatricoma is a benign skin neoplasm of hair follicle matrix cells. Calcification is a common finding while dystrophic ossification also can occur in the tumour. Histopathology gives the definite diagnosis as fine needle aspiration cytology and clinical impression may be misleading.

It is generally accepted that ongoing medication overuse nullifies the effect of prophylactic treatment, although few data support this contention. We set out to describe the treatment outcome in patients withdrawn from medication overuse and relate any improvement to a renewed effect of prophylaxis. For patients with probable medication-overuse headache (pMOH), treated and dismissed from the Danish Headache Centre in 2002 and 2003, we assed, from prospective headache diaries, the headache frequency before and after withdrawal of offending drugs and compared these frequencies with the headache frequency at dismissal. Among 1326 patients, 337 had pMOH. Eligible were 175, mean age 49 years, male/female ratio 1: 2.7. Overall, there was a 46% decrease in headache frequency from the first visit to dismissal ( P < 0.0001). Patients with no improvement 2 months after complete drug withdrawal ( N = 88) subsequently responded to pharmacological and/or non-pharmacological prophylaxis with a 26% decrease in headache frequency as measured from the end of withdrawal to dismissal ( P < 0.0001). At dismissal, 47% were on prophylaxis. Former non-responders to medical prophylaxis had a 49% decrease in headache frequency from first visit to dismissal ( P < 0.0001), whereas those who had never received prophylaxis had a 56% reduction ( P < 0.0001). This difference was not statistically significant ( P = 0.22). Almost all MOH patients benefit from drug withdrawal, either just from the withdrawal or by transformation from therapeutic non-responsiveness to responsiveness. According to the International Classification of Headache Disorders, 2nd edn, the MOH diagnosis requires improvement after drug withdrawal. Our data suggest that these diagnostic criteria are too strict.

A stone is not only an obstacle, sometimes painful, on the urinary tract justifying an emergency urological gesture to restore their permeability. It is primarily a symptom of crystallogenic pathologies or urinary imbalances of nu-tritional origin whose recurrence is the rule if the cause has not been correctly identified. It is therefore recommended in the patient's interest; analyze the calcul or its fragments to determine its composition and structure, one and / or the other orienting towards the pathology in question. A series of 166 urinary stones were collected nearby the hospitals of western Algeria after urological intervention or spontaneous expulsion and sequential analysis of the nucleus at the surface by Fourier transform infrared spectrophotometry. The male / female ratio was 1.78. The study of the anatomical localization of the stones showed a predominance of the high urinary tract with a rate of 76.9%. 27.3% of the stones were located in the left kidney compared to 25.7% in the right kidney. Analysis of the crystalline composition showed that calcium oxalate was predominant in 65.8% of the calculs and in 58.5% of the nuclei. In all, whewellite was present in 46.9% of cases and weddellite in 18.9%. uric acid anhydrous was the major component of 12.2% of the calculations analyzed. It was present in 23.3% of cases with predominance in subjects over 60 years. Our results show that the lithiasis of the urinary tree in western Algeria tends to evolve in the same direction as that of the industri-alized countries.
