Graduation and military service

In 1902, La Cava graduated with honors and was offered a free job working with Professor Antonio Cardarelli, who had observed his medical abilities; financial constraints prevented him from accepting it.^[3] So, he began his military career as a medical officer in the Bersaglieri Corps in Florence and when he returned to Calabria in 1904, he took over the tiny rural management of Bovalino where he met Concettina Morisciano, a noble, intelligent young Bovalinese woman with whom he had ten children. They married on 30 June 1907; their house became a gathering place for guests who enjoyed discussing about science and medicine as well as art and literature.^[4]

Studies about tropical diseases

The Bovalino Clinic's management did not force him to forsake his scientific research; on the contrary, his continued efforts were rewarded with the discovery of cases of tropical diseases never seen in Europe before. He treated these ailments and also studied them theoretically, publishing his findings in journals and speaking at conferences.^[5]

The first case was published in Gazzetta Medica No. 21, "A Case of Dengue Fever", followed by many publications co-authored with Professor Gabbi, professor of exotic diseases at the University of Rome.^[5]

In 1911, La Cava released a paper titled "On the Presence of Leishmanie in the Cerebrospinal Fluid of a Child with Kala-azar",^[6] that highlighted key factors to determine the disease's diagnosis: they observed that the "eastern button" was frequent and recognized the focus of the inquiry; a female dog in which they discovered Leishmania parasites. Furthermore, La Cava learnt that Dr. Rogers, an English tropical disease expert, had found emetine hydrochloride as a therapy for amebiasis; he was able to treat the cases of dysentery he had diagnosed in Bovalino.^[6]

The consequences of the Great War

The tremendous international events of 1914 generated issues in the La Cava household: La Cava served at Gerace before being called to the front as "director of various field hospitals" in May 1915. He was relocated to Rome as a director of the Aurelio Saffi Hospital at the end of 1917 and in the 1920s, after completing his service at the military hospital, worked at the War Pensions Commission.^[7]

Concettina, La Cava's wife, was devastated by his departure, as she was left alone in Bovalino with their two children. As a short diary entitled "Diario della vita che passai quando il mio caro Ciccio si trovava in guerra di liberazione dei nostri fratelli" reveals, Concetta proved to be not only a woman, but also an outstanding wife during these difficult years.^[7]

Moving to Rome

Around the end of 1917, La Cava, who had been promoted to army major, was posted to the Aurelio Saffi Reserve Hospital in Rome. After coming in the city, his first thought was to bring his family with him, thus they all moved to Via Po at Coppedè neighborhood.^[7]

He also began to acquire a large clientele and, during the Spanish flu, worked often for free, to care for the sick. The essence of La Cava's existence and work, centered on his love for people and his profession, was exposed by his attitude toward individuals who could not afford treatment.^[7]

Unexpected death

On the last Sunday of May 1958, at the age of eighty-two, he died suddenly. He had gone to vote in his neighborhood in Rome, accompanied by his son Virgilio, when he collapsed from a heart attack under the watchful eyes of his son and the rescuers. Many newspapers covered his demise, paying tribute to his being and works. His body lays in Careri's cemetery.^[8]

Artistic writings

The deep humanistic culture, the knowledge of Latin and Greek, combined with the love of art, led La Cava to visit museums and galleries to analyze in depth many problems with the meticulousness and patience typical of a doctor. He also analyzed Michelangelo's life and works, and published conclusions in 1925 in "The Face of Michelangelo Discovered at the Final Judgment." During the 1930s La Cava expanded his Christian faith by focusing on theological and philological topics, such as "The Passion and Death of Jesus Christ as depicted by medical science" and "Communion Eucharistic through the stomach fistula".^[3] He was extremely passionate about medical history, he wrote a text on Lombardy's health history, "Hygiene and Health in the Statutes of Milan in the XV century", and an article on the epidemic of 1575-1578, "The Plague of St. Charles seen by a doctor".^[3]

Religious writings

Around 1930 he experienced a rapprochement to religion, from which he had distanced because of the liberal ideas he had embraced since his college days; this renewed faith led him to scientific-religious studies on the mechanism of death by crucifixion.

Thus, in 1930, the text ''Did Jesus Christ suffer from pleurisy? Mechanism of death by crucifixion''^[13] analyzes the blow of the spear of Longinus on the side of the dead Jesus, which caused the outflow of blood and water. According to La Cava, the azygos vein filled with blood due to the prolonged inhalation, the pressure of which caused the exudation of serum and hydrothorax due to congestion in the pleural cavity. In 1944 he published in Latin a scientific-religious work entitled "On Eucharistic Communion through Gastric Fistula. Physiological-Exegetical Reflections of a Catholic Physician".^[14] This work deals with the possibility of introducing the consecrated host directly into the stomach, this problem was already a subject of reflection among moral theologians, divided into those who considered the direct introduction of the host into the stomach sufficient to produce the sacramental effects of the Eucharist and those who considered the reception by mouth, "manducation" essential for the efficacy of the sacrament.^[14]

The spirit and intentions with which the doctor wrote these works can be felt in the introduction of the 1953 publication, which recalls the bad reputation gained by those doctors among the faithful who dealt with the naturalistic point of view of the mysteries of faith.^[15]

Philological writings

In his house, always full of friends, circulated the figure of the Jesuit priest Gaetani, who edited the preface of the 1953 work and with whom Francesco liked to discuss philological issues.^[15] In 1934 he published: "Ut videntes non Videant" a work in which he deals with the problem of the function of parables, beginning with a philological analysis of the Gospel text .La Cava prosecute his studies with the meticulous sense of research that distinguished him, and in 1935, in another work entitled "Ne quando convertantur", he continued the analysis of the passage of the Evangelist Mark .
