RESUMO
Brachymetatarsia is a condition in which a metatarsal bone does not grow out to full length. This is caused by premature physeal closure. The proximal phalanx associated with the shortened metatarsal helps achieve the natural parabola of the foot. A hypoplastic proximal phalanx is a common finding in patients with brachymetatarsia. The goal of this study was to determine the length of the proximal phalanx in the setting of brachymetatarsia, and how much the shortening is attributed to the clinically smaller toe. We performed a retrospective study to evaluate the length of the proximal phalanx in the shortened ray. After the metatarsal was brought out to the desired length of correction, the proximal phalanx was measured on radiographs. Ninety-seven feet with congenital brachymetatarsia were reviewed in a cohort of 66 patients who underwent surgical correction between January 2005 and February 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27.5 years. The average length of the proximal phalanx associated with the affected metatarsal was noted to be 18.9 ± 3.83 mm for males and 15.6 ± 4.02 mm for females. Our results indicate the shortened proximal phalanx is 5 mm shorter when compared to normal population and is a contributing factor to the shortened clinical appearance of the digit in brachymetatarsia. Treating surgeons should be aware of this to better educate patients on the influence of the digit on the overall shortening seen in cases of brachymetatarsia.

Brachymetatarsia is caused by premature closure of the physis and is characterized by a short metatarsal. Additional foot conditions may exist in patients presenting with brachymetatarsia, such as hallux valgus (HV). A retrospective study was performed to evaluate the prevalence of HV and brachymetatarsia in the ipsilateral foot. Ninety-seven feet with congenital brachymetatarsia were reviewed in a multi-study cohort of 66 patients who underwent surgical correction between January 2005 and August 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27 years. HV deformities were verified with standardized anteroposterior radiographs. HV was present in 29 of 97 feet for a prevalence of 30% in the feet with brachymetatarsia. Our results demonstrate a 30% prevalence of HV associated with brachymetatarsia. This information is helpful for foot and ankle surgeons managing brachymetatarsia to determine appropriate conservative or surgical management of this condition.

The human immunodeficiency virus (HIV) is currently a global threat with an estimated 38.6 million people affected with HIV worldwide. According to the Joint United Nations Program on HIV/AIDS (UNAIDS), since 2004 the total number of cases of HIV in Pakistan has risen from 2700 to 130,000. In light of the rising burden of HIV/AIDS across the country, it is essential that medical students possess appropriate knowledge regarding the subject. Therefore, we aimed to assess the knowledge, attitude and practice of medical students towards HIV patients in their pre-clinical and post-clinical years in Karachi, Pakistan. A cross-sectional study was conducted among 518 pre-clinical (year 1 and 2) and post-clinical (year 3, 4, and 5) medical students from two medical schools in Karachi during the months of October - December 2019. Similar numbers of participants were taken from each year. Data were analyzed using SPSS. Descriptive statistics were used to report frequencies and proportions for categorical responses. Chi-square and Kruskal-Wallis tests were used as the primary statistical tests. About 55% of participants were female, and most belonged to the Islamic faith. More than half of the participants learned about HIV from books (315/518), followed by medical personnel (287/518). A quarter (134/518) of the participants believed HIV could be transmitted by sharing saliva, more than half of whom consisted of pre-clinical year students. Over half the participants (60.4%) knew that there was a difference between HIV and AIDs, most of whom belonged to the 5th year group. When detecting HIV, only about 30% of participants knew about indirect fluorescent antibody. Regarding attitudes, one-third would not be friends with a person diagnosed with HIV/AIDS. As a medical officer, a large majority (76.6%; n=397/518) of the participants would be anxious or somewhat anxious. Two-thirds believed that treating an HIV patient can make them contract HIV, and a majority of participants (333/518) did not feel adequately prepared to deal with the psycho-social problems of an HIV/AIDS patient. Finally, regarding practice, only one-third of the participants were willing to treat an HIV/AIDS patient, most of whom belonged to the pre-clinical 2nd year group and fewer to the post-clinical 3rd year group. Knowledge amongst medical students regarding HIV/AIDS was generally high, although there are some knowledge inadequacies which require more emphasis in the medical school curriculum. However, contrasting with the level of knowledge, in terms of attitude the majority were anxious or somewhat anxious when treating an HIV patient, and only one-third were willing to treat a patient with HIV.
