Diaphragmatic hernias may be acquired or congenital. Among congenital hernias, the most common is Bochdalek hernia and eight out of ten Bochdalek hernias occur on the left side. They are usually diagnosed in the paediatric age group, and it is exceedingly rare for the diagnosis to be established in adulthood. Renal ectopy associated with a Bochdalek hernia is extremely rare, and very few cases are reported worldwide. We are reporting a case of a 73-year-old male patient with a right-sided Bochdalek hernia and renal ectopy. In this case, promp diagnosis and treatment could help to reduce the high risk of death in this kind of patients.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 461 Mexicans from the state of Chihuahua living in Chihuahua city (N = 119), Ciudad Juárez (N = 106) and rural communities (N = 236), to obtain information regarding allelic and haplotypic frequencies and their linkage disequilibrium. We find that the most frequent haplotypes found in the state of Chihuahua include seven Native American and three European haplotypes. Admixture estimates revealed that the main genetic components in Chihuahua are European (52.12 ± 0.88% by ML; 41.53% of European haplotypes) and Native American (39.51 ± 2.17% by ML; 37.45% of Native American haplotypes), while African genetic component was less apparent (8.36 ± 1.47% by ML; 11.70% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 95 Mexicans from the state of Aguascalientes to obtain information regarding allelic and haplotypic frequencies and their linkage disequilibrium. We find that the most frequent haplotypes in the state of Aguascalientes include four Native American, three European and one Asian haplotypes. Admixture estimates revealed that the main genetic components in the state of Aguascalientes are Native American (54.53 ± 3.22% by ML; 44.21% of Native American haplotypes) and European (44.34 ± 0.45% by ML; 40.53% of European haplotypes), and a relatively low African genetic component (1.13 ± 2.33% by ML; 5.26% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 117 Mexicans from the state of San Luis Potosí living in the city of San Luis Potosí (N = 30) and rural communities (N = 87), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes in the state include 13 Native American, six European, two African and two Asian haplotypes. Admixture estimates revealed that the main genetic components are Native American (52.72 ± 0.66% by ML; 48.29% of Native American haplotypes) and European (34.62 ± 4.28% by ML; 32.48% of European haplotypes), and a relatively high African genetic component (12.66 ± 4.61% by ML; 10.26% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 684 Mexicans from the state of Coahuila living in Saltillo (N = 72), Torreón (N = 396) and rural communities (N = 216), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes found in the state of Coahuila include eight Native American and two European haplotypes. Admixture estimates revealed that the main genetic components in the state of Coahuila are European (49.72 ± 4.18% by ML; 37.49% of European haplotypes) and Native American (45.01 ± 2.69% by ML; 42.98% of Native American haplotypes), while African genetic component is less apparent (5.27 ± 1.88% by ML; 9.92% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 148 Mexicans from the state of Tamaulipas living in Ciudad Victoria (N = 23) and rural communities (N = 125), to obtain information regarding allelic and haplotypic frequencies. We found that the most frequent haplotypes in the state of Tamaulipas include ten Native American, three European and one African haplotypes. Admixture estimates revealed that the main genetic components in the state of Tamaulipas are Native American (54.69 ± 0.93% by ML; 47.65% of Native American haplotypes) and European (34.66 ± 5.62% by ML; 33.56% of European haplotypes), and a relatively high African genetic component (10.65 ± 5.05% by ML; 12.42% of African haplotypes).

Achilles tendon rupture is one of the most frequent tendon ruptures. Surgical intervention is the best option, but it has a high rate of complications leading to skin infections and necrosis. Extensive and aggressive debridement is necessary, producing tendon exposure and large skin defects. There are many alternatives for the skin coverage of the Achilles tendon, like sequential closures, vacuum assisted closure, local flaps, regional flaps, and more recently and efficiently microsurgery flaps. Skin defects in the Achilles tendon region have many peculiarities in comparison with other parts of the body: it is a zone that is always under mechanical stress due to footwear, this is why it must be highly resistant but thin. Its coverage must have sensitive properties, endure tendon gliding and allow early rehabilitation. Sometimes tendon reinforcement or creation or a neo tendon will be needed. For fulfilling these requirements free flaps by microsurgery are the only option in 90% of the cases. In this review article, we analyze three of the most frequently used free flaps in reconstructive medicine for complex Achilles tendon defects; free radial forearm flap, free radial forearm flap with vascularized flexor carpi radialis tendon and free anterolateral thigh (ALT) flap with vascularized fascia lata. This choice will be determined by the number of tissues involved, size of the defect, etiology of the defect, overall condition of the affected extremity and quality of neighboring tissues.

The Sister Mary Joseph Nodule is an eponymous term which describes a palpable umbilical nodule occurring as a result of metastasis of an intra-abdominal or pelvic malignancy. In approximately 50% of cases, this sign is associated with gastrointestinal malignancies. These include gastric, colonic and pancreatic (mainly body and tail) carcinoma. Gastrointestinal malignancy is found in 52% of the metastatic cases and gynecologic and genitourinary origin in 28%, with gastric and ovarian cancers being the most common. The next report is about a 62 year-old woman whose was referred to the surgery department due a painful mass on the abdominal wall that has appeared 3 months before as a fast-growing, with suspicious diagnosis of strangulated umbilical hernia.
